SHOULD BE READ IN CONJUNCTION WITH, THE MORE DETAILED INFORMATION AND THE
CONSOLIDATED FINANCIAL STATEMENTS AND NOTES THERETO APPEARING ELSEWHERE IN THIS
PROSPECTUS. THIS PROSPECTUS CONTAINS CERTAIN FORWARD-LOOKING STATEMENTS THAT
INVOLVE RISKS AND UNCERTAINTIES. THE COMPANY'S ACTUAL RESULTS COULD DIFFER
MATERIALLY FROM THOSE DISCUSSED IN THE FORWARD-LOOKING STATEMENTS AS A RESULT OF

(II) NO EXERCISE OF THE OVER-ALLOTMENT OPTION GRANTED TO THE UNDERWRITERS.
 
                                  THE COMPANY
 
    Carreker-Antinori is a leading provider of integrated consulting and
software solutions that enable banks to increase their revenues, reduce their
costs and enhance their delivery of customer services. The Company's offerings
include yield management, payment systems, payment electronification and
enabling technologies solutions. Carreker-Antinori's solutions assist banks in
re-engineering their operational systems and implementing new software
applications to increase earning assets, develop new revenue sources, improve
operating efficiencies and reduce check fraud losses. The Company believes that
its 20 years of experience in the banking industry, combined with its advanced
technological expertise, positions it to effectively address and anticipate the
challenges and opportunities faced by banks in today's increasingly competitive
environment. The Company's customers include approximately two-thirds of the
largest 100 bank holding companies in the United States, including Fleet
Financial Group, Inc., NationsBank Corporation, Norwest Corporation and SunTrust
Banks, Inc.
 
    The banking industry is one of the nation's largest industries, with
aggregate annual revenues of nearly $250 billion. In recent years, the industry
has undergone significant change, and today's banking environment is
characterized by intense competition, continuing consolidation, changing
regulations and rapid technological innovation. In addition to increased
competition within the banking industry, banks are encountering significant
competition from insurance companies, brokerage houses and other financial
institutions, all of which are expanding to provide services that were once
within the exclusive domain of banks. While banks historically have focused on
reducing their operating expenses to remain competitive, they are today
increasingly focusing on developing new sources of revenue growth, automating
operations to increase efficiencies and outsourcing commodity-like banking
functions to sustain market value growth. To this end, banks are expending
significant resources, both internally and through outsourcing arrangements.
Information technology expenditures by the industry in 1997 on paper-based
payment systems and financial and risk management systems alone are estimated to
have been approximately $1.0 billion and $2.3 billion, respectively, of which
approximately 59% and 51% were paid to third parties.
 
    The Company's offerings include yield management, payment systems, payment
electronification and enabling technologies solutions. The Company's yield
management solutions are designed to quickly increase a bank's revenues through
improved operational workflows, pricing structures and liquidity and cash
management. The Company's payment systems and payment electronification
solutions are designed to reduce check-processing costs through procedural and
technological improvements and reduced check fraud and other risks of loss.
Carreker-Antinori's enabling technologies convert leading-edge technologies and
ideas into practical banking solutions. The Company's solutions are
differentiated by virtue of Carreker-Antinori's industry-specific consulting
expertise, advanced technology and broad array of integrated, value-added
solutions. The Company's objective is to be the leading provider of yield
management, payment systems, payment electronification and enabling technologies
solutions that enhance the competitiveness of banks. Carreker-Antinori plans to
accomplish this objective by: (i) advancing its position as a leading industry
innovator; (ii) pursuing strategic alliances and acquisitions; (iii) leveraging
its market position to expand its customer base; and (iv) building long-term
customer relationships.
 
    The Company believes that it derives a significant competitive advantage by
providing leadership to the banking industry through its association with two
high-profile interbank organizations: the Electronic Check Clearing House
Organization ("ECCHO"), which is focused on developing the rules and standards
for transitioning the check payment system from paper to electronic formats, and
Payment Solutions Network, Inc. ("PSN"), which provides database and
information-based products and services critical to the realization of the
benefits associated with the electronification of the check payment system. The
Company's role in these interbank organizations enables it to be an
infrastructure development partner to the banking industry, enhancing the
Company's ability to provide value-added benefits to banks today and uniquely
positioning it to take advantage of the electronification of payment systems in
the future. In addition, the Company has recently partnered with Fiserv, Inc.,

    offering upon the exercise by a Selling Stockholder of options under the
    Company's Long Term Incentive Plan (the "Long Term Incentive Plan") to
    purchase shares of Common Stock, as well as the issuance of 1,159,882 shares
    upon the exercise of options outstanding under the Long Term Incentive Plan
    that terminate if unexercised contemporaneously with the offering. The
    Company has established a stock option loan program to facilitate the
    exercise of such options. See "Certain Transactions--Stock Option Loan
    Program" and "Principal and Selling Stockholders." Excludes: (i) 3,793,418
    shares of Common Stock reserved for issuance under the Long Term Incentive
    Plan of which options to purchase 2,408,783 shares are outstanding at a
    weighted average exercise price of $5.77 per share; (ii) 100,000 shares of
    Common Stock reserved for issuance under the Company's Director Stock Option
    Plan (the "Director Plan"), none of which are outstanding; and (iii) 276,315

(2) Prior to the Company's acquisition of Antinori Software, Inc., a Georgia
    corporation ("ASI"), on January 31, 1997, ASI had elected to be treated as
    an S corporation for federal and state income tax purposes. The provision
    for income tax included as a component of net income for the fiscal years
    prior to fiscal 1997 reflects a pro forma tax provision which includes
    estimated federal and state income taxes (by applying statutory income tax
    rates) that would have been incurred if ASI had been subject to taxation as
    a C corporation.

CONSIDERED CAREFULLY IN EVALUATING AN INVESTMENT IN THE SHARES OF COMMON STOCK
OFFERED HEREBY. FURTHER, THIS PROSPECTUS CONTAINS CERTAIN FORWARD-LOOKING
STATEMENTS THAT INVOLVE RISKS AND UNCERTAINTIES, SUCH AS STATEMENTS OF THE

STATEMENTS MADE IN THIS PROSPECTUS APPLY TO ALL RELATED FORWARD-LOOKING
STATEMENTS WHEREVER THEY APPEAR IN THIS PROSPECTUS. PROSPECTIVE INVESTORS IN THE
SHARES OF COMMON STOCK OFFERED HEREBY ARE CAUTIONED THAT, WHILE THE
FORWARD-LOOKING STATEMENTS REFLECT THE COMPANY'S GOOD FAITH BELIEFS, THEY ARE
NOT GUARANTEES OF FUTURE PERFORMANCE, AND INVOLVE KNOWN AND UNKNOWN RISKS AND
UNCERTAINTIES. IN ADDITION, THE COMPANY'S ACTUAL RESULTS COULD DIFFER MATERIALLY
FROM THOSE DISCUSSED HEREIN. SOME OF THE FACTORS THAT COULD CAUSE OR CONTRIBUTE
TO SUCH DIFFERENCES INCLUDE THOSE DISCUSSED BELOW, AS WELL AS THOSE DISCUSSED
ELSEWHERE IN THIS PROSPECTUS.
 
DEPENDENCE ON BANKING INDUSTRY
 
    The Company derives substantially all of its revenues from solutions
provided to banks and other participants in the banking industry. Accordingly,
the Company's future success significantly depends upon the continued demand for
its solutions within this industry. The Company believes that an important
factor in its growth has been the substantial change in the banking industry, as
manifested by continuing consolidation, regulatory change, technological
innovation and other trends. If this environment of change were to slow, the
Company could experience reduced demand for its solutions. In addition, the
banking industry is sensitive to changes in economic conditions and is highly
susceptible to unforeseen events, such as political instability, recession,
inflation or other adverse occurrences that may result in a significant decline
in the utilization of bank services. Any event that results in decreased
consumer or corporate use of bank services, or increased pressures on banks
towards the in-house development and implementation of revenue enhancement or
cost reduction measures, could have a material adverse effect on the Company's
business, financial condition and results of operations. See "Business--Industry
Background."
 
FLUCTUATIONS IN QUARTERLY OPERATING RESULTS
 
    The Company has experienced in the past, and expects to experience in the
future, significant fluctuations in quarterly operating results. Such
fluctuations may be caused by many factors, including but not limited to the
extent and timing of revenues recognized, and costs incurred, under
value-pricing contracts, the degree of customer acceptance of new solutions, the
introduction of new or enhanced solutions by the Company or its competitors,
budget concerns of customers, competitive conditions in the industry, seasonal
factors, bank purchasing cycles, timing of consolidation decisions by banks, the
extent of
their international expansion and general economic conditions. See "--Customer
Project Risks." In addition, the volume and timing of contract signings during a
quarter are difficult to forecast, particularly in light of the Company's
historical tendency to have a disproportionately large portion of contract
signings in the final weeks of a quarter. Due to the foregoing factors, many of
which are beyond the Company's control, quarterly revenues and operating results
are difficult to forecast. It is possible that the Company's future quarterly
results of operations from time to time will not meet the expectations of
securities analysts or investors, which could have a material adverse effect on
the market price of the Company's Common Stock. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations-- Selected Quarterly
Results of Operations."
 
LIMITED OPERATING HISTORY AS A COMBINED COMPANY
 
    In January 1997, the Company acquired ASI. Accordingly, the Company has only
a limited operating history as a combined company upon which an evaluation of
the Company and its prospects can be based, and is subject to the risks
generally inherent in the establishment and growth of a new business enterprise.
The Company is still in the process of integrating ASI's business, management
information systems,
 
                                       6
<PAGE>
software products and other operations with the Company's operations. There can
be no assurance that the Company will be able to integrate successfully ASI's
operations or institute integrated Company-wide systems and procedures to manage
successfully the combined enterprise on a profitable basis. The inability of the
Company to integrate successfully ASI's operations could have a material adverse
effect on the Company's business, financial condition and results of operations.
In addition, because the Company's consolidated financial results of operations
reflect only one fiscal year of actual integration of the operations of the
Company and ASI, these results of operations should not be relied upon as any
indication of future performance. See "Certain Transactions--Merger with
Antinori Software, Inc."
 
CUSTOMER CONCENTRATION
 
    The Company's five largest customers accounted for approximately 49%, 38%
and 46% of total revenues during fiscal 1995, 1996 and 1997, respectively. While
the Company's significant customers have changed from period to period, Norwest
Corporation has consistently ranked as one of the Company's top customers, and
accounted for approximately 16%, 16% and 14% of total revenues in fiscal 1995,
1996 and 1997, respectively. The Company's largest customer in fiscal 1997 was
Fleet Financial Group, Inc., which accounted for approximately 15% of total
revenues in that period. There can be no assurance that the Company will be
successful in maintaining its existing customer relationships or in securing
additional major customers, and there can be no assurance that the Company can
retain or increase the volume of business that it does with such customers. Any
failure by the Company to retain one or more of its large customers, maintain or
increase the volume of business done for such customers or establish profitable
relationships with additional customers would have a material adverse effect on
the Company's business, financial condition and results of operations.
 
CUSTOMER PROJECT RISKS
 
    The Company prices its solutions on a time-and-materials, fixed-price and
value-pricing basis. In connection with fixed-price projects, the Company
occasionally incurs expenses in excess of its projected costs, and, as a result,
achieves lower margins than expected or may incur losses with respect to
projects. In connection with value-priced projects, the Company is paid based on
an agreed percentage of either projected or actual increased revenues or
decreased costs derived by the bank over a period of up to twelve months
following the implementation of the Company's solution. The Company typically
must first incur significant expenses to develop such projections before a bank
will commit to purchase the Company's solutions, and therefore assumes the risk
of incurring expenses with no assurance that the bank will purchase the
solutions. In addition, from time to time, a customer will not achieve projected
revenues or savings because it belatedly decides not to implement the Company's
solutions or the solutions do not produce the projected results, in which case
the Company may not be able to collect any or all of the fees provided for in
the customer's contract. The nature of the Company's fixed-price and
value-pricing arrangements can result in decreased operating margins or losses
and could materially and adversely affect the Company's business, financial
condition and results of operations. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations--Overview," "Business--The
Carreker-Antinori Solution--Reduced Customer Risk" and "--Strategy--Increase Use
of High-Margin Pricing Arrangements."
 
ABILITY TO MANAGE GROWTH
 
    The Company has experienced significant growth in recent years, and
anticipates that additional expansion may be required in order to address
potential market opportunities. Any expansion of the Company's business would
place further demands on the Company's management, operational capacity and
financial resources. The Company anticipates that it will need to recruit large
numbers of qualified personnel in all areas of its operations, including
management, sales, marketing, delivery and software development. There can be no
assurance that the Company will be effective in attracting and retaining
 
                                       7
<PAGE>
additional qualified personnel, expanding its operational capacity or otherwise
managing growth. In addition, there can be no assurance that the Company's
systems, procedures or controls will be adequate to support any expansion of the
Company's operations. The Company is currently in the process of updating its
management information system (the "MIS system"), which could require the
Company to provide additional training to existing personnel or hire additional
personnel. If the Company cannot implement the new MIS system in a timely
manner, the Company's ability to manage growth effectively or generate timely
quarterly reports could be materially and adversely affected. The failure to
manage growth effectively could have a material adverse effect on the Company's
business, financial condition and results of operations. See
"Business--Strategy--Pursue Strategic Alliances and Acquisitions."
 
MARKET ACCEPTANCE OF THE COMPANY'S SOLUTIONS
 
    The Company's success depends upon continued demand for its solutions.
Market acceptance of the Company's existing and future solutions depends on
several factors including: (i) the ease with which such solutions can be
implemented and used; (ii) the performance and reliability of such solutions;
(iii) the degree to which customers achieve expected revenue gains, cost savings
and performance enhancements; and (iv) the extent to which the Company's
customers and prospective customers are able to implement alternative approaches
to meet their business development and cost-saving needs. Some of the foregoing
factors are beyond the Company's control. There can be no assurance that the
Company's customers will realize the intended benefits of the Company's
solutions or that the Company's solutions will achieve continued or increased
market acceptance. Any significant or ongoing failure to achieve such benefits
or to maintain or increase market acceptance would restrict substantially the
future growth of the Company and could have a material adverse effect on the
Company's business, financial condition and results of operations. See
"Business--Products and Services."
 
ABSENCE OF LONG-TERM AGREEMENTS
 
    The Company typically provides services to customers on a project-by-project
basis without long-term agreements. When a customer defers, modifies or cancels
a project, the Company must be able to rapidly redeploy its personnel to other
projects in order to minimize the underutilization of its personnel and the
resulting adverse impact on operating results. In addition, the Company's
operating expenses are relatively fixed and cannot be reduced on short notice to
compensate for unanticipated variations in the number or size of projects in
progress. As a result, any termination, significant reduction or modification of
its business relationships with any of its significant customers or with a
number of smaller customers could have a material adverse effect on the
Company's business, financial condition and results of operations. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Overview" and "Business--Sales and Marketing."
 
POTENTIAL FOR SOFTWARE AND/OR SOLUTIONS DEFECTS
 
    The Company's solutions at times in the past have been, and in the future
may be, incompatible with the operating environments of its customers or
inappropriate to address their needs, resulting in additional costs being
incurred by the Company in rendering services to its customers. Further, like
other software products, the Company's software occasionally has contained
undetected errors, or "bugs," which become apparent through use of the software.
Because the Company's new or enhanced software initially is installed at a
limited number of sites and operated by a limited number of users, such errors
and/or incompatibilities may not be detected for a number of months after
delivery of the software. The foregoing errors in the past have resulted in the
deployment of Company personnel and funds to cure errors, resulting in cost
overruns and delays in solutions development and enhancement. Moreover,
solutions with substantial errors could be rejected by or result in damages to
customers, which could have a material adverse effect on the Company's business,
financial condition and results of operations. There can be no assurance that
errors or defects will not be discovered in the future, potentially causing
delays in solution
 
                                       8
<PAGE>
implementation or requiring design modifications that could adversely affect the
Company's business, financial condition and results of operations. It is also
possible that errors or defects in the Company's solutions could give rise to
liability claims against the Company. See "Business--Technology."
 
COMPETITION
 
    The Company competes with third-party providers of services and software
products to the banking industry, including firms providing consulting services,
such as Andersen Consulting, Electronic Data Systems Corporation and KMPG Peat
Marwick LLP, and software companies, such as Earnings Performance Group, Inc.,
Pegasystems Inc., Sterling Software, Inc. and Transoft International, Inc. Many
of these competitors have significantly greater financial, technical, marketing
and other resources than the Company. The Company's competitors may be able to
respond more quickly to new or emerging technologies and changes in customer
requirements or to devote greater resources to the development, promotion and
sale of their products than can the Company. Also, several of the Company's
current and potential competitors have greater name recognition and larger
customer bases that such competitors could leverage to increase market share at
the Company's expense. The Company expects to face increased competition as
other established and emerging companies enter the banking services market.
Increased competition could result in price reductions, fewer customer orders
and loss of market share, any of which could materially and adversely affect the
Company's business, financial condition and results of operations. There can be
no assurance that the Company will be able to compete successfully against
current or future competitors, and the failure to do so would have a material
adverse effect upon the Company's business, financial condition and results of
operations. See "Business--Competition."
 
    In addition to competing with a variety of third parties, the Company
experiences competition from its customers and potential customers. From time to
time, these potential customers develop, implement and maintain their own
services and applications for revenue enhancements, cost reductions and/or
enhanced customer services, rather than purchasing services and related products
from third parties. As a result, the Company must continuously educate existing
and prospective customers about the advantages of purchasing its solutions.
There can be no assurance that these customers or other potential customers will
perceive sufficient value in the Company's solutions to justify investing in
them. In addition, customers or potential customers could enter into strategic
relationships with one or more of the Company's competitors to develop, market
and sell competing services or products.
 
USE OF INDEPENDENT CONTRACTORS
 
    The Company often provides solutions through independent contractors and,
therefore, does not pay federal or state employment taxes or withhold income
taxes for such persons. Further, the Company does not include these independent
contractors in its employee benefit plans. From time to time persons engaged as
independent contractors are determined to be employees as a result of challenges
by the Internal Revenue Service (the "IRS") and state authorities asserted in
administrative proceedings or court actions. In certain instances, persons
engaged to be independent contractors also could initiate court proceedings
asserting that they are employees under state law and, therefore, are entitled
to participate in employee benefit plans. Such determinations of employee status
are made on a case-by-case basis and are based upon the particular facts of each
case. In the event persons engaged by the Company as independent contractors are
determined to be employees by the IRS or any state taxation department, the
Company would be required to pay applicable federal and state employment taxes
and withhold income taxes with respect to such persons and could become liable
for amounts required to be paid or withheld in prior periods. In addition, the
Company could be required to include such persons in its employee benefit plans
on a retroactive, as well as a current, basis. At January 31, 1998, 60
consultants were engaged by the Company as independent contractors, and any
challenge by the IRS, state authorities or private litigants resulting in a
determination that such persons are employees would have a material adverse
effect on the Company's business, financial condition and results of operations.
In October 1997, a bill was introduced in the United States House of
Representatives that would amend the Internal Revenue Code to establish
 
                                       9
<PAGE>
more stringent requirements for the engagement of independent contractors. The
Company is unable to assess the likelihood that this bill or similar legislation
will be enacted. Further, the Company's ability to retain independent
contractors could in the future deteriorate, due in part to the lower commitment
level that such contractors have to the Company. See "Business--Independent
Contractors."
 
DEPENDENCE ON KEY PERSONNEL
 
    The Company's future success depends, in significant part, upon the
continued services of John D. Carreker, Jr., its Chairman of the Board and Chief
Executive Officer, as well as other executive officers and key personnel. The
loss of services of Mr. Carreker or one or more of the Company's other executive
officers or key employees could have a material adverse effect on the Company's
business, financial condition and results of operations, and there can be no
assurance that the Company will be able to retain its executive officers or key
personnel. See "Management."
 
ABILITY TO ATTRACT AND RETAIN QUALIFIED PERSONNEL
 
    The Company's future success depends upon its continuing ability to attract
and retain highly qualified banking, technical and managerial personnel.
Competition for such personnel is intense, and the Company at times has
experienced difficulties in attracting the desired number of such individuals.
Further, the Company's employees frequently have left the Company to work
in-house with the Company's customers. There can be no assurance that the
Company will be able to attract or retain a sufficient number of highly
qualified employees or independent contractors in the future. If the Company is
unable to attract personnel in key positions, the Company's business, financial
condition and results of operations could be materially and adversely affected.
 
IMPACT OF TECHNOLOGICAL ADVANCES
 
    The Company's future success will depend, in part, upon its ability to
enhance its existing solutions, develop and introduce new solutions that address
the increasingly sophisticated and varied needs of its current and prospective
customers, develop leading technology and respond to technological advances and
emerging industry standards on a timely and cost-effective basis. There can be
no assurance that future advances in technology will be beneficial to, or
compatible with, the Company's business or that the Company will be able to
incorporate such advances into its business. In addition, keeping abreast of
technological advances in the Company's business may require substantial
expenditures and lead time. There can be no assurance that the Company will be
successful in using new technologies, adapting its solutions to emerging
industry standards or developing, introducing and marketing solution
enhancements or new solutions, or that the Company will not experience
difficulties that could delay or prevent the successful development,
introduction or marketing of these solutions. If the Company incurs increased
costs or is unable, for technical or other reasons, to develop and introduce new
solutions or enhancements of existing solutions in a timely manner in response
to changing market conditions or customer requirements, the Company's business,
financial condition and results of operations could be materially and adversely
affected. See "Business--Solutions Development."
 
DEPENDENCE ON PROPRIETARY TECHNOLOGY; RISK OF INFRINGEMENT
 
    The Company's success significantly depends upon its proprietary technology
and information. The Company relies upon a combination of patent, copyright,
trademark and trade secret laws and confidentiality procedures to protect its
proprietary technology and information. The Company generally has relied on
common law rights to protect the use of its name, technology and brands. The
Company has a number of issued patents and one registered trademark. There can
be no assurance that the steps taken by the Company to protect its services and
products are adequate to prevent misappropriation of its technology or that the
Company's competitors independently will not develop technologies that are
substantially equivalent or superior to the Company's technology. Further, it is
very difficult to police unauthorized use of the Company's software due to the
nature of software. Any such misappropriation of the Company's
 
                                       10
<PAGE>
proprietary technology or information or the development of competitive
technologies could have a material adverse effect on the Company's business,
financial condition and results of operations. In addition, the laws of certain
countries in which the Company's software is distributed do not protect the
Company's intellectual property rights to the same extent as the laws of the
United States. For example, the laws of a number of foreign jurisdictions in
which the Company licenses its software protect trademarks solely on the basis
of the first to register. The Company currently does not possess any trademark
registrations in foreign jurisdictions, although it does have copyright
protection of its software under the provisions of various international
conventions. Accordingly, intellectual property protection of its services and
products may be ineffective in many foreign countries. In summary, there can be
no assurance that the protection provided by the laws of the United States or
such foreign jurisdictions will be sufficient to protect the Company's
proprietary technology or information.
 
    The Company could incur substantial costs in protecting and enforcing its
intellectual property rights. Although presently there are no pending or
threatened intellectual property claims against the Company, third parties may,
in the future, assert patent, trademark, copyright and other intellectual
property right claims to technologies which are incorporated into the Company's
solutions. In such event, the Company may be required to incur significant costs
in reaching a resolution to the asserted claims. There can be no assurance that
such a resolution would not require that the Company pay damages or obtain a
license to the third party's intellectual property rights in order to continue
licensing the Company's software as currently offered or, if such a third-party
license is required, that it would be available on terms acceptable to the
Company.
 
    Certain technology used in the Company's current software and software in
development includes technology licensed from third parties. These licenses
generally require the Company to pay royalties and to fulfill confidentiality
obligations. The termination of any such licenses, or the failure of the
third-party licensors to adequately maintain or update their products, could
result in delays in the Company's ability to implement solutions or in delays in
the introduction of the Company's new or enhanced solutions while it searches
for similar technology from alternative sources, if any, which would prove
costly. Any need to implement alternative technology could prove to be very
expensive for the Company and any delay in solution implementation could result
in a material adverse effect on the business, financial condition and results of
operations of the Company. It may also be necessary or desirable in the future
to obtain additional licenses for use of third-party products in the Company's
solutions and there can be no assurance that the Company will be able to do so
on commercially reasonable terms, if at all. See "Business--Proprietary Rights."
 
YEAR 2000 COMPLIANCE
 
    Many currently installed computer systems and software products are coded to
accept only two-digit entries in the date code field. Beginning in the year
2000, these date code fields will need to accept four-digit entries to
distinguish 21st century dates from 20th century dates. As a result, computer
systems and/or software used by many companies, including those used by
Carreker-Antinori, may need to be upgraded to comply with such "Year 2000"
requirements. In addition, if banks dedicate a significant portion of their
information budgets to the resolution of Year 2000 issues, their ability to
purchase the Company's solutions may be adversely affected, which could have a
material adverse effect on the Company's business, financial condition and
results of operations. Although most of the software currently offered by the
Company is either designed to be Year 2000 compliant or has been upgraded to be
Year 2000 compliant, the Company still offers some software which is not Year
2000 compliant. The Company is in the process of correcting this situation for a
number of its customers. There can be no assurance that the Company's Year 2000
compliant software contains all necessary date code changes or that such
software will interface with its customers' other software programs. Further,
liability claims could arise out of the Company's delivery of solutions that
address Year 2000 issues to the extent that such solutions do not effectively
address such issues, and the failure of such solutions to effectively address
Year 2000 issues could have a material adverse effect on the Company's business,
financial condition and results of operations. In addition,
 
                                       11
<PAGE>
although the Company believes that each of the software programs used in the MIS
system and other internal programs is Year 2000 compliant, there can be no
assurance that such software will be Year 2000 compliant, and any failure to be
so compliant may require additional expenditures by the Company to rectify the
noncompliance.
 
POTENTIAL LIABILITY CLAIMS
 
    As a result of the Company's provision of solutions that address critical
functions of bank operations, the Company is exposed to possible liability
claims from banks and their customers. Although the Company has not experienced
any material liability claims to date, there can be no assurance that the
Company will not become subject to such claims in the future. A liability claim
against the Company could have a material adverse effect on its business,
financial condition and results of operations.
 
RISKS ASSOCIATED WITH POTENTIAL STRATEGIC ALLIANCES OR ACQUISITIONS
 
    Except as described immediately below, the Company has no current agreements
or negotiations underway with respect to any potential strategic alliances or
acquisitions. The Company does, however, regularly evaluate such opportunities
and may enter into strategic alliances or make acquisitions of other companies
or technologies in the future. Risks inherent in alliances include, among
others: (i) substantial investment of the Company's resources in the alliance;
(ii) inability to realize the intended benefits of an alliance; (iii) increased
reliance on third parties; (iv) increased payment of third-party licensing fees
or royalties for the incorporation of third-party technology into the Company's
solutions; and (v) inadvertent transfer of the Company's proprietary technology
to strategic "partners." Acquisitions involve numerous risks, including
difficulties in assimilating acquired operations and products, diversion of
management's attention from other business concerns, amortization of acquired
intangible assets and potential loss of key employees of acquired companies.
There can be no assurance that the Company will be successful in identifying and
entering into strategic alliances, if at all, and any inability to do so could
have a material adverse effect on the Company's business, financial condition
and results of operations. In addition, there can be no assurance that the
Company will be able to integrate successfully any operations, personnel or
services that might be acquired in the future, and a failure by the Company to
do so could have a material adverse effect on the Company's business, financial
condition and results of operations. See "Business-- Strategy."
 
    The Company is currently providing management services to ECCHO and PSN,
which enables it to be an infrastructure development partner to the banking
industry. These relationships, and the Company's participation in INFITEQ, are
forms of strategic alliances. The Company has made investments in, and has
extended credit to, these entities to support their growth. The Company has
experienced, and may continue to experience, delays in collections of management
fees from these respective strategic alliances. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Liquidity and Capital
Resources" and "Business--Strategic Banking Initiatives."
 
GOVERNMENT REGULATION
 
    The Company's primary customers are banks. Although the solutions currently
offered by the Company have not been subject to any material, specific
government regulation, the banking industry is regulated heavily, and the
Company expects that such regulation will affect the relative demand for the
Company's solutions. There can be no assurance that federal, state or foreign
governmental authorities will not adopt new regulations, and any adoption of new
regulations could require the Company to modify its current or future solutions.
The adoption of laws or regulations affecting the Company's or its customers'
business could reduce the Company's growth rate or could otherwise have a
material adverse effect on the Company's business, financial condition and
results of operations. See "Business--Government Regulation."
 
                                       12
<PAGE>
RISKS ASSOCIATED WITH INTERNATIONAL OPERATIONS
 
    The Company recently has begun to provide solutions to banks outside the
United States, and a key component of the Company's growth strategy is to
broaden its international operations. The Company's international operations are
subject to risks inherent in the conduct of international business, including
unexpected changes in regulatory requirements, exchange rates, export license
requirements, tariffs and other economic barriers to free trade, political and
economic instability, limited intellectual property protection, difficulties in
collecting payments and potentially adverse tax and labor consequences. Certain
of the Company's international sales are denominated in local currencies, and
the impact of future exchange rate fluctuations on the Company's financial
condition and results of operations cannot be accurately predicted. There can be
no assurance that fluctuations in currency exchange rates in the future will not
have a material adverse effect on revenue from international sales and thus the
Company's business, financial condition and results of operations. See
"Business--Strategy."
 
MANAGEMENT'S DISCRETION AS TO USE OF UNALLOCATED NET PROCEEDS
 
    The Company has designated only limited specific use for the net proceeds to
the Company from the sale of Common Stock in the offering. The Company expects
to use the net proceeds for working capital and other general corporate
purposes, as well as possible strategic alliances and acquisitions.
Consequently, the Board of Directors and management of the Company will have
broad discretion in allocating a significant portion of the net proceeds to the
Company from the offering. The failure of management to apply such funds
effectively could have a material adverse effect on the Company's business,
financial condition and results of operations. See "Use of Proceeds."
 
CONTROL BY OFFICERS AND DIRECTORS
 
    Upon completion of the offering, the Company's executive officers and
directors will beneficially own, in the aggregate, 63.0% of the Company's
outstanding Common Stock (58.8% if the Underwriters' over-allotment option is
exercised). Accordingly, these persons, if acting together, will have
substantial control over matters requiring approval by the stockholders of the
Company, including the election of directors. See "--Anti-Takeover Matters,"
"Management" and "Principal and Selling Stockholders."
 
SHARES ELIGIBLE FOR FUTURE SALE
 
    Upon completion of the offering, the Company will have an aggregate of
16,742,664 shares of Common Stock outstanding. Of these shares, all of the
shares sold in the offering will be freely transferable without restriction or
limitation under the Securities Act of 1933, as amended (the "Securities Act"),
except for any shares purchased by "affiliates" of the Company, as such term is
defined in Rule 144 under the Securities Act. The remaining 11,642,664 shares
constitute "restricted securities" within the meaning of Rule 144, and the
resale of such shares is restricted for one year from the date they were
acquired. Of these "restricted securities," 10,697,792 shares have been held for
the required one-year period and will be freely tradeable upon completion of the
offering, subject to the 180-day lock-up period described below. The remaining
944,872 "restricted securities" have not been held for the requisite one-year
period and, upon completion of the offering, will be tradeable after the
expiration of the lock-up period and subject to the volume and price limitations
of Rule 144. The holders of 8,443,448 shares have certain rights to have shares
registered in the future under the Securities Act pursuant to the terms of
agreements between such holders and the Company. The Company, its executive
officers, directors and principal and other stockholders who will hold,
collectively, 5,749,764 shares of Common Stock after the offering, have agreed
not to offer or sell any shares of Common Stock for a period of 180 days
following the date of this Prospectus without the prior written consent of
BancAmerica Robertson Stephens, except that the Company may issue shares of
Common Stock in connection with acquisitions and pursuant to the exercise of
stock options described in this Prospectus. On the date of this Prospectus, the
Company had outstanding options to purchase 2,408,783 shares of Common Stock
granted pursuant to the Long Term Incentive Plan,
 
                                       13
<PAGE>
of which 1,825,061 shares are not subject to lock-up agreements and may be
eligible for sale beginning 90 days following the date of this Prospectus. The
Company intends to register all of the shares of Common Stock reserved for
issuance pursuant to the Long Term Incentive Plan and the Director Plan under
the Securities Act for public resale. Sales of substantial amounts of shares of
Common Stock in the public market after the offering, or the perception that
such sales could occur, may adversely affect the market price of the Common
Stock. See "Shares Eligible for Future Sale."
 
IMMEDIATE AND SUBSTANTIAL DILUTION
 
    Purchasers of Common Stock in the offering will incur immediate and
substantial dilution in the amount of $8.13 per share, at an assumed initial
public offering price of $11.00 per share. To the extent that outstanding
options to purchase the Common Stock are exercised, there will be further
dilution. See "Dilution."
 
ANTI-TAKEOVER MATTERS
 
    The Company's Certificate of Incorporation (the "Certificate") and Bylaws
("Bylaws") contain provisions that may have the effect of delaying, deterring or
preventing a potential takeover of the Company that stockholders purchasing
shares in the offering may consider to be in their best interests. The
Certificate and Bylaws provide for a classified Board of Directors serving
staggered terms of three years, prevent stockholders from calling a special
meeting of stockholders and prohibit stockholder action by written consent. The
Certificate also authorizes only the Board of Directors to fill vacancies,
including newly-created directorships, and states that directors of the Company
may be removed only for cause and only by the affirmative vote of holders of at
least two-thirds of the outstanding shares of the voting stock, voting together
as a single class. Section 203 of the Delaware General Corporation Law, which is
applicable to the Company, contains provisions that restrict certain business
combinations with interested stockholders, which may have the effect of
inhibiting a non-negotiated merger or other business combination involving the
Company. See "Description of Capital Stock--Delaware Anti-Takeover Law and
Certain Charter Provisions."
 
ABSENCE OF A PRIOR PUBLIC MARKET
 
    Prior to the offering, there has been no public market for the Common Stock,
and there can be no assurance that an active trading market will develop or be
sustained. The initial public offering price of the Common Stock will be
determined through negotiations among the Company, the Selling Stockholders and
the Underwriters and may not be indicative of the market price for the Common
Stock after the offering. See "Underwriting" for a discussion of the factors to
be considered in determining the initial public offering price.
 
POTENTIAL VOLATILITY OF STOCK PRICE
 
    The market price for the Common Stock following the offering will be
affected by a number of factors, including the announcement of new products,
product enhancements or services by the Company or its competitors, quarterly
variations in the Company's results of operations or results of operations of
the Company's competitors, changes in earnings estimates or recommendations by
securities analysts, developments in the Company's industry and in the banking
industry, general market and economic conditions and other factors, including
factors unrelated to the operating performance of the Company or its
competitors. In addition, stock prices for many companies in the technology and
emerging growth sectors have experienced wide fluctuations which have often been
unrelated to the operating performance of such companies. Such factors and
fluctuations may adversely affect the market price of the Company's Common
Stock.

<PAGE>
                                USE OF PROCEEDS
 
    The net proceeds to the Company from its sale of 3,650,000 shares of Common
Stock offered hereby at an assumed initial public offering price of $11.00 per
share are estimated to be $36.5 million ($37.2 million if the Underwriters'
over-allotment option is exercised in full), after deducting the estimated
underwriting discount and estimated offering expenses payable by the Company.
The Company will not receive any of the proceeds from the sale of shares of
Common Stock by the Selling Stockholders.
 
    The principal purposes of the offering are to increase the Company's equity
capital, to create a public market for the Common Stock, to facilitate the
future access by the Company to public equity markets, to provide liquidity for
certain of the Company's existing stockholders and to provide increased
visibility of the Company in a marketplace where many of its competitors are
publicly-held companies.
 
    The Company intends to use the proceeds of the offering for working capital
and other general corporate purposes, including expenses related to the
recruitment and retention of additional personnel associated with the Company's
anticipated growth. The Company may also use a portion of the net proceeds for
possible strategic alliances and acquisitions of businesses, products and
technologies that are complementary to those of the Company. Pending such uses,
the Company plans to invest the net proceeds in short-term, interest-bearing,
investment-grade securities.
 
    The Company continues to evaluate potential strategic alliances and
acquisitions, and to identify and have preliminary discussions with potential
strategic alliance and/or acquisition candidates, although there are, as of the
date of this Prospectus, no agreements, arrangements or understandings between
the Company and any party relating thereto.
 
                                DIVIDEND POLICY
 
    The Company has not paid a cash dividend on shares of its Common Stock since
its incorporation (although prior to its acquisition by the Company, ASI did
make cash dividend payments principally to enable its shareholders to pay income
taxes arising out of ASI's status as an S corporation). The Company currently
intends to retain its earnings in the future to support operations and finance
its growth and, therefore, does not intend to pay cash dividends on the Common
Stock in the foreseeable future. Any payment of cash dividends in the future
will be at the discretion of the Board of Directors and subject to certain
limitations under the Delaware General Corporation Law and will depend upon
factors such as the Company's earnings levels, capital requirements, financial
condition and other factors deemed relevant by the Board of Directors. The
Company is prohibited from paying cash dividends under the terms of its current
line of credit agreement. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Liquidity and Capital Resources."

                                    DILUTION
 
    The net tangible book value of the Company as of January 31, 1998 was $6.4
million, or $0.53 per share of Common Stock. Net tangible book value per share
is equal to the Company's total tangible assets less total liabilities, divided
by the total number of shares of Common Stock outstanding. After giving effect
to the sale of 3,650,000 shares of Common Stock offered by the Company hereby
(at an assumed initial public offering price of $11.00 per share) and after
deduction of the estimated underwriting discounts and estimated offering
expenses payable by the Company and the application of the estimated net
proceeds therefrom, the adjusted net tangible book value of the Company as of
January 31, 1998 would have been approximately $44.9 million or $2.87 per share.
This represents an immediate increase in net tangible book value of $2.34 per
share to existing stockholders and an immediate dilution of $8.13 per share to
new investors purchasing shares of Common Stock in the offering. The following
table illustrates this dilution:

(1) Sales by the Selling Stockholders in the offering will reduce the number of
    shares held by existing stockholders to 11,642,664 shares, or 69.5% of the
    total shares of Common Stock outstanding after this offering, and will
    increase the number of shares held by new investors to 5,100,000 shares, or
    30.5% of the total shares of Common Stock outstanding after the offering. If
    the Underwriters' over-allotment option is exercised in full, the number of
    shares held by new investors will increase to 5,865,000 shares, or 34.9% of
    the total shares of Common Stock outstanding after the offering. See
    "Principal and Selling Stockholders."
 
    The foregoing computations assume no exercise of outstanding stock options,
other than the assumed exercise of 462,000 options by a Selling Stockholder
contemporaneously with the offering and the assumed exercise of 1,159,882
options that will otherwise terminate if unexercised contemporaneously with the
completion of the offering. See "Certain Transactions--Stock Option Loan
Program" and "Principal and Selling Stockholders." Options to purchase 2,408,783
shares of Common Stock are outstanding under the Company's Long Term Incentive
Plan at a weighted average exercise price of $5.77 per share and options to
purchase 276,315 shares of Common Stock are outstanding at a weighted average
exercise price of $0.58 per share and are held by the Company's non-employee
directors. To the extent these options are exercised, there will be further
dilution to new investors in the offering. See "Management--Long Term Incentive
Plan" and "--Director Stock Option Plan."

- ------------------------
(1) Prior to the Company's acquisition of ASI on January 31, 1997, ASI had
    elected to be treated as an S corporation for federal and state income tax
    purposes. The provision for income tax included as a component of net income
    for the fiscal years prior to fiscal 1997 reflects a pro forma tax provision

    THE FOLLOWING DISCUSSION CONTAINS FORWARD-LOOKING STATEMENTS THAT INVOLVE
RISKS AND UNCERTAINTIES. THE COMPANY'S ACTUAL RESULTS COULD DIFFER MATERIALLY
FROM THOSE DISCUSSED IN THE FORWARD-LOOKING STATEMENTS AS A RESULT OF CERTAIN
FACTORS INCLUDING THOSE SET FORTH UNDER "RISK FACTORS" AND ELSEWHERE IN THIS

WITH "SELECTED CONSOLIDATED FINANCIAL DATA" AND THE CONSOLIDATED FINANCIAL
STATEMENTS AND NOTES THERETO APPEARING ELSEWHERE IN THIS PROSPECTUS.
 
OVERVIEW
 
    Carreker-Antinori is a leading provider of integrated consulting and
software solutions that enable banks to increase their revenues, reduce their
costs and enhance their delivery of customer services. The Company was founded
in 1978 to provide consulting services to banks, and subsequently integrated
software products into its banking solutions. With its acquisition of Antinori
Software, Inc., a Georgia corporation ("ASI"), the Company was able to
significantly enhance its portfolio of software products. The acquisition of ASI
was accounted for as a pooling of interests and, accordingly, the Company's
Consolidated Financial Statements and Notes thereto, as well as all other
financial and statistical data presented in this Prospectus, have been restated
to include ASI's financial position and results of operations for all periods
prior to and including the period ended January 31, 1997.
 
    The Company derives its revenues from consulting and management service
fees, software license fees, software maintenance and implementation fees and
hardware sales. While many customer contracts provide for both the performance
of consulting services and the license of related software, some customer
contracts require only the performance of consulting services or only a software
license (and, at the election of the customer, related implementation services
and/or annual software maintenance services). The Company enters into these
contracts with its customers on a project-by-project basis. The Company also
derives management service fees from the performance of comprehensive management
services for ECCHO, PSN and INFITEQ.
 
    A substantial majority of the Company's revenues are generated from
contracts with bank holding companies with assets over $50 billion ("Tier I
Banks") and bank holding companies and independent banks with assets of between
$5 billion and $50 billion ("Tier II Banks"). The Company seeks to establish
long-term relationships with its customers that will lead to on-going projects
utilizing the Company's solutions. The Company is typically retained to perform
one or more discrete projects for a customer, and uses these opportunities to
extend its solutions into additional areas of the customer's operations. To this
end, approximately 74% and 85% of the Company's total revenues in fiscal 1997
were derived from companies who were customers of the Company in fiscal 1995 and
fiscal 1996, respectively. See "Business--Customers and Markets."
 
    CONSULTING AND MANAGEMENT SERVICE FEES.  The Company employs three primary
pricing methods in connection with its delivery of consulting and management
services. First, the Company may price its delivery of consulting and management
services on the basis of time and materials, in which case the customer is
charged agreed daily rates for services performed and out-of-pocket expenses. In
such a case, fees and related amounts are generally payable on a monthly basis,
and revenue is recognized as the services are performed. Second, consulting and
management services may be delivered on a fixed-price basis. In this case,
payments are made to the Company on a monthly basis or pursuant to an agreed
upon payment schedule, and revenue is recognized on a percentage-of-completion
basis. Any anticipated losses on a fixed-price contract are recognized when
estimable. Third, the Company may deliver consulting and management services
pursuant to a value-pricing contract with the customer. In this case, the
Company is paid, on an agreed upon basis with the customer, either a specified
percentage of (i) the projected increased revenues or decreased costs that are
expected to be derived by the customer over a period of up to twelve months
following implementation of the Company's solution or (ii) the actual increased
revenues and/or decreased costs experienced by the customer over a period of up
to twelve months following implementation of the Company's solution, subject in
either case to a ceiling, if any is agreed to, on the total amount of payments
to
 
                                       19
<PAGE>
be made to the Company. Such contracts typically provide for the Company to
receive from 10% to 30% of the projected or actual increased revenues or
decreased costs, with payments to be made to the Company pursuant to an agreed
upon schedule ranging from one to twelve months in length. Revenues generated
from rendering consulting and management services in connection with
value-priced contracts based upon projected results are recognized only upon
completion of all services and agreement upon the actual fee to be paid. When
fees are to be paid based on a percentage of actual revenues or savings, the
Company recognizes revenue as the amounts of actual revenues or savings are
confirmed by the customer. The Company typically must first incur significant
expenses to develop projections associated with value-pricing contracts before a
bank will commit to purchase the Company's solutions, and therefore assumes the
risk of incurring expenses with no assurance that the bank will purchase the
solutions. The Company expects that value-pricing contracts will account for an
increasing percentage of its revenues in the future. In addition, as a
consequence of the shift toward the use of more value-pricing contracts and due
to the revenue recognition policy associated with those contracts, the Company's
results of operations will likely fluctuate significantly from period to period.
See "--Selected Quarterly Results of Operations." Regardless of the pricing
method employed by the Company in a given contract, the Company is reimbursed on
a monthly basis for out-of-pocket expenses incurred on behalf of its customers,
which expenses are netted against reimbursements for financial statement
reporting purposes.
 
    SOFTWARE LICENSE FEES.  In the event that a software license is granted
together with consulting and management services or on a stand-alone basis,
software license fees are payable to the Company in one or more installments, as
provided in the customer's contract. Software license fees are recognized upon
delivery, provided that: (i) the Company has no significant remaining
obligations under the contract; (ii) the fees are collectible; and (iii) the
fees for other components of the solution can be separately identified. Software
licenses continue for an indefinite period and there is no provision for any
renewal fees. The Company also enters into value-pricing contracts in connection
with its grant of software licenses, in which case payments are made and revenue
is recognized in a fashion similar to that for such contracts in the consulting
and management services context. Although substantially all of the Company's
current software licenses provide for a set license fee, whether pursuant to a
fixed-price or value-pricing contract, some of the Company's payment
electronification licenses instead provide for per-transaction license fees (in
which case fees are recognized and due on a monthly basis). The Company expects
to increase its practice of charging license fees on a per-transaction basis in
the future as part of its strategy to increase recurring revenues and smooth its
period-to-period revenues. See "Business--Strategy--Increase Use of High-Margin
Pricing Arrangements."
 
    SOFTWARE MAINTENANCE AND IMPLEMENTATION FEES.  In connection with the
Company's sale of a software license, a customer may elect to purchase software
implementation services or software maintenance services, including software
enhancements, patches and other software support services. Most of the customers
that purchase software licenses from the Company also purchase both software
implementation services and software maintenance services (the latter of which
typically are renewed annually). The Company prices its implementation services
on a time-and-materials or on a fixed-price basis, and the related revenues are
recognized on a basis consistent with that applied to consulting and management
services. The Company charges an annual maintenance fee typically ranging from
15% to 20% of the initial software license fee, which generally is payable to
the Company at the beginning of the maintenance period and is recognized ratably
over the term of the related contract.
 
    HARDWARE SALES.  The Company's computer hardware sales are made in tandem
with the delivery of related services or software, and are sold on the basis of
the Company's cost plus a specified percentage. Revenues are recognized upon
shipment of the hardware to the customer. The Company sells hardware at the
request of its customers, but does not consider hardware sales to be a
meaningful part of its business.
 
    In accordance with generally accepted accounting principles, the Company
capitalizes software development costs incurred in developing a product once
technological feasibility of the product has been determined. These capitalized
software development costs also include amounts paid for software that is
 
                                       20
<PAGE>
purchased and that has reached technological feasibility. Capitalized software
development costs are amortized on the basis of each product's projected revenue
or on a straight-line basis over the remaining economic life of the product
(generally three to five years). At January 31, 1998, the Company's capitalized
software development costs, net of accumulated amortization, were $2.3 million,
which will be amortized over the next 12 to 20 quarterly periods. See Note 2 of
Notes to Consolidated Financial Statements.

</TABLE>
 
YEAR ENDED JANUARY 31, 1997 (FISCAL 1996) COMPARED TO YEAR ENDED JANUARY 31,
  1998 (FISCAL 1997)
 
    REVENUES.  The Company's total revenues increased by 39.2% from $29.1
million in fiscal 1996 to $40.5 million in fiscal 1997. The increase was
primarily attributable to growth in revenues from consulting and management
services and software licenses. Revenues from consulting and management services
increased by 47.9% from $14.4 million in fiscal 1996 to $21.3 million in fiscal
1997. This increase reflected both continued demand for the Company's services,
as well as greater use of value-pricing arrangements. Software license revenues
increased 59.4% from $6.4 million in fiscal 1996 to $10.2 million in fiscal
1997. Software license revenue growth stemmed from growth in the number of
products offered and the use of value pricing for appropriate engagements during
fiscal 1997. Software maintenance and implementation revenues increased by 27.6%
from $5.8 million in fiscal 1996 to $7.4 million in fiscal 1997. High renewals
by existing maintenance customers, coupled with maintenance agreements generated
from new license sales, contributed to growth in this area. Hardware sales
decreased 36.0% from $2.5 million in fiscal 1996 to
 
                                       21
<PAGE>
$1.6 million in fiscal 1997. This decrease was primarily due to reduced requests
by customers for bundled hardware and license deliveries.
 
    COST OF REVENUES.  Cost of revenues consists generally of personnel costs,
amortization of capitalized software development costs, third-party royalties
and cost of hardware delivered. Total cost of revenues increased by 36.7% from
$15.0 million in fiscal 1996 to $20.5 million in fiscal 1997. This increase
resulted primarily from an increase in the cost of revenues in consulting and
management services and software maintenance and implementation. Cost of
revenues for consulting and management services increased by 40.9% from $8.8
million in fiscal 1996 to $12.4 million in fiscal 1997, which was a result
primarily of increases in personnel. Cost of revenues of software licenses
increased by 7.7% from $1.3 million in fiscal 1996 to $1.4 million in fiscal
1997. Cost of revenues of software maintenance and implementation increased by
74.2% from $3.1 million in fiscal 1996 to $5.4 million in fiscal 1997, which was
primarily due to increases in personnel costs associated with the Company's
growth and, to a lesser extent, services related to INFITEQ. Cost of revenues
for hardware sales decreased 23.5% from $1.7 million in fiscal 1996 to $1.3
million in fiscal 1997 due to reduced hardware sales levels, but increased as a
percentage of hardware sales from 70.7% in fiscal 1996 to 86.0% in fiscal 1997
due to pricing pressures. Total cost of revenues as a percentage of total
revenues decreased from 51.4% in fiscal 1996 to 50.7% in fiscal 1997. While cost
of revenues decreased as a percentage of total revenues, certain elements of
cost increased. These costs increased due, in part, to delays in the development
of certain software applications. In addition, sales and implementations of
products under value-pricing engagements caused the recognition of costs during
the period for efforts where revenue may be recognized in a later period.
 
    SELLING, GENERAL AND ADMINISTRATIVE.  Selling, general and administrative
expenses generally consist of personnel costs associated with selling,
marketing, general management and software management, as well as fees for
professional services and other related costs. Selling, general and
administrative expenses increased by 33.7% from $8.6 million in fiscal 1996 to
$11.5 million in fiscal 1997. The increase in these expenses reflected the
addition of management and marketing staff during late fiscal 1996 and fiscal
1997 associated with the Company's growth. As a percentage of revenues, selling,
general and administrative expenses decreased from 29.8% in fiscal 1996 to 28.5%
in fiscal 1997.
 
    RESEARCH AND DEVELOPMENT.  Research and development expenses generally
consist of personnel and related costs of developing solutions. Research and
development expenses increased by 183.3% from $1.2 million in fiscal 1996 to
$3.4 million in fiscal 1997. Research and development expenses as a percentage
of revenues increased from 4.0% in fiscal 1996 to 8.5% in fiscal 1997. Growth in
research and development expenses resulted largely from an increase in the
number of development efforts during fiscal 1997. See "--Overview." Furthermore,
in addition to planned research and development efforts during fiscal 1997, the
Company undertook to redevelop certain components of one of its software
applications. As a consequence of this undertaking, as well as other software
development projects, research and development expenses in the third and fourth
quarters of fiscal 1997 were higher than historical levels.
 
    MERGER RELATED COSTS.  Merger related costs consisted of one-time
compensation expense of $589,000 attributable to the accelerated vesting during
fiscal 1996 of an option granted to an executive of ASI during fiscal 1995, as
well as one-time transaction costs of $834,000 related to the acquisition of ASI
by the Company.
 
    OTHER INCOME (EXPENSE), NET.  Other income (expense) increased from
($386,000) in fiscal 1996 to $99,000 in fiscal 1997. Other income (expense)
consists of interest income (net) and non-recurring income (expense) relating to
PSN. During fiscal 1996, the Company recorded a reserve of $500,000 to reflect
the potential uncollectibility of a loan made to PSN.
 
    PROVISION FOR INCOME TAXES.  Income tax provision increased from $1.1
million in fiscal 1996 to $2.1 million in fiscal 1997, reflecting an effective
tax rate of 44.9% for fiscal 1996 compared with 40.2% for fiscal 1997. Fiscal
1996 included a pro forma tax on earnings of ASI, as ASI was not subject to tax
as an S corporation (see Note 5 of Notes to Consolidated Financial Statements).
The effective tax rate in fiscal 1996 was larger compared to fiscal 1997
primarily due to the merger with ASI. The Company incurred
 
                                       22
<PAGE>
$500,000 of nondeductible merger costs which increased the fiscal 1996 effective
tax rate. Without the impact of merger related costs, the fiscal 1996 effective
tax rate would have been 37%.
 
YEAR ENDED JANUARY 31, 1996 (FISCAL 1995) COMPARED TO YEAR ENDED JANUARY 31,
  1997 (FISCAL 1996)
 
    REVENUES.  The Company's total revenues increased by 57.3% from $18.5
million in fiscal 1995 to $29.1 million in fiscal 1996. The increase was the
result of growth in each of the Company's business lines. Revenues from
consulting and management services increased by 50.0% from $9.6 million in
fiscal 1995 to $14.4 million in fiscal 1996 as a result of an increase in
engagements coupled with an increase in the number of value-priced arrangements.
Software license revenues increased 73.0% from $3.7 million in fiscal 1995 to
$6.4 million in fiscal 1996. Growth in software license revenues primarily
resulted from the successful rollout of the RESERVELINK product, which accounted
for approximately $2.2 million of the growth. Software maintenance and
implementation revenues increased by 38.1% from $4.2 million in fiscal 1995 to
$5.8 million in fiscal 1996. Software maintenance and implementation revenues
increased by over $1.6 million as a result of RESERVELINK sales. Hardware sales
increased 127.3% from $1.1 million in fiscal 1995 to $2.5 million in fiscal
1996. Increased requests by customers for bundled hardware and license
deliveries generated the increase.
 
    COST OF REVENUES.  Total cost of revenues increased by 63.0% from $9.2
million in fiscal 1995 to $15.0 million in fiscal 1996. This increase resulted
primarily from an increase in the cost of revenues related to consulting and
management services and software licenses. Cost of revenues in consulting and
management services increased by 66.0% from $5.3 million in fiscal 1995 to $8.8
million in fiscal 1996, which primarily resulted from increases in personnel.
Cost of revenues of software licenses increased by 85.7% from $700,000 in fiscal
1995 to $1.3 million in fiscal 1996, which was caused primarily by increases in
royalty costs driven by growth in software license sales. Cost of revenues of
software maintenance and implementation increased by 29.2% from $2.4 million in
fiscal 1995 to $3.1 million in fiscal 1996. This increase was attributable
predominantly to increased personnel. Cost of revenues for hardware sales
increased 125.8% from $753,000 in fiscal 1995 to $1.7 million in fiscal 1996.
This increase resulted from increased hardware sales during fiscal 1996.
 
    SELLING, GENERAL AND ADMINISTRATIVE.  Selling, general and administrative
expenses increased 50.9% from $5.7 million in fiscal 1995 to $8.6 million in
fiscal 1996. This increase resulted from increases in management, marketing and
sales staff, combined with larger bonus payments and fees for professional
services. Selling, general and administrative expenses as a percentage of
revenues decreased from 30.7% in fiscal 1995 to 29.8% in fiscal 1996.
 
    RESEARCH AND DEVELOPMENT.  Research and development expenses increased 32.5%
from $906,000 in fiscal 1995 to $1.2 million in fiscal 1996. This increase
reflected the Company's continued efforts to develop additional software
applications and enhancements to certain of its existing applications.
 
    OTHER INCOME (EXPENSE), NET.  Other income (expense) decreased 227.0% from
$304,000 in fiscal 1995 to ($386,000) in fiscal 1996. Interest income (net)
increased 111.1% from $54,000 during fiscal 1995 to $114,000 during fiscal 1996.
The Company recognized investment income of $250,000 in fiscal 1995 and
investment expense of $500,000 in fiscal 1996. Investment income during fiscal
1995 represented cash collected from PSN resulting from the sale of the
Company's interest in PSN during fiscal 1995. The investment expense during
fiscal 1996 represents the establishment of an allowance for the potential that
amounts loaned to PSN during fiscal 1996 may not be collectible.
 
    PROVISION FOR INCOME TAXES.  Income tax provision decreased from $1.2
million in fiscal 1995 to $1.1 million in fiscal 1996, reflecting an effective
tax rate of 38.5% for fiscal 1995 compared with 44.9% for fiscal 1996. Both
fiscal years included a pro forma tax on the earnings of ASI, as ASI was not
subject to tax as an S corporation (see Note 5 of Notes to Consolidated
Financial Statements). The increase in the effective tax rate from fiscal 1995
to fiscal 1996 primarily resulted from the impact that nondeductible merger
costs had on the fiscal 1996 provision.

SELECTED QUARTERLY RESULTS OF OPERATIONS
 
    The following table sets forth certain unaudited quarterly data for each of
the Company's last eight quarters ended January 31, 1998. Such data are
expressed as a percentage of the Company's total revenues for the periods
indicated. The data have been derived from the Company's unaudited consolidated
financial statements that, in management's opinion, include all adjustments
(consisting only of normal recurring adjustments) necessary for a fair
presentation of such information when read in conjunction with the Consolidated

    In the quarter ended October 31, 1996, total revenues increased $3.4 million
over the prior quarter due to a substantial delivery of software during the
period combined with corresponding implementation services. As a result, net
income for the quarter increased by nearly $1.0 million. During the following
quarter, revenues returned to more normal levels, while net income declined to a
loss of $575,000 due primarily to one-time merger related costs.
 
    In the quarter ended July 31, 1997, consulting and management service fees
increased $2.6 million over the prior quarter due to the completion and closing
of two value-priced projects. From time to time, the Company has experienced,
and will likely experience in the future, fluctuations in revenues due to the
timing of revenue recognition. See "--Overview" and "Risk Factors--Fluctuations
in Quarterly Operating Results."
 
    In the quarters ended October 31, 1997 and January 31, 1998, research and
development costs increased due to growth in personnel in order to accelerate
the delivery of solutions to meet contract commitments. Research and development
staffing levels continued to increase through the quarter ended January 31, 1998
to meet internal schedules for the completion of multiple development efforts.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    During fiscal 1996 and 1997, the Company funded its activities through cash
provided by operations. Cash provided by operating activities during fiscal 1996
and 1997 was $2.4 million and $1.6 million, respectively. At January 31, 1997
and 1998, the Company had working capital of $5.7 million and $7.4 million,
respectively.
 
    Cash used in investing activities during fiscal 1996 was $1.9 million, and
was primarily related to working capital loans made to PSN, purchases of
property and equipment and development of capitalized software. Cash used in
investing activities during fiscal 1997 was $3.3 million, and was primarily
related to purchases of property and equipment, purchases of software and
development of software. The Company established a reserve of $500,000 in fiscal
1996 to address the potential uncollectibility of working capital loans made to
PSN. In addition, the Company has experienced in the past, and may experience in
the future, delays in collecting trade receivables due to it from PSN.
 
    Cash generated through financing activities for fiscal 1996 resulted
primarily from the sale of treasury stock to the Crow Family Partnership, L.P.
for $834,050. Additionally, during fiscal 1996 ASI made distributions to its
shareholders totaling $1.0 million for the payment of their personal income
taxes resulting from ASI's status as an S corporation. Cash generated through
financing activities for fiscal 1997 resulted primarily from the exercise of
stock options for $159,000 and the net sale of treasury stock for $68,000.
 
    The Company has a $3.0 million revolving credit facility (the "Facility").
As of January 31, 1998, the Company had no amounts outstanding under the
Facility. Principal amounts outstanding under the Facility bear interest at
national prime (8.5% at January 31, 1998). Availability under the Facility is
calculated based on 70% of qualified accounts receivable. All indebtedness under
the Facility matures on July 1, 1998. Under the Facility, the Company is subject
to certain covenants regarding its operations and corporate actions, such as
restrictions relating to creation of liens, borrowing of funds, changes in
control, liquidation and dividends.
 
    The Company believes that the net proceeds from the offering, existing cash
resources and cash flows from operations will be sufficient to fund the
Company's operations for at least the next twelve months. See "Use of Proceeds"
for more information regarding possible future capital requirements.
 
    The Company has taken actions to address the nature and extent of the work
required to make its products and systems Year 2000 compliant. The majority of
the Company's products are currently Year 2000 compliant and the remainder of
the Company's products are targeted to be Year 2000 compliant by April 1998. The
Year 2000 compliance activities will be performed as part of the Company's
normal
 
                                       25
<PAGE>
development activity. The Company does not believe it will incur any significant
Year 2000 costs associated with its internal systems. As a consequence, Year
2000 compliance costs are not expected to result in any material incremental
costs to the Company. See "Risk Factors--Year 2000 Compliance."
 
RECENTLY ISSUED ACCOUNTING STANDARDS
 
    The Accounting Standards Executive Committee of the American Institute of
Certified Public Accountants has issued Statement of Position No. 97-2 "Software
Revenue Recognition" ("SOP 97-2"), which supersedes Statement of Position No.
91-1. The new SOP 97-2 will be effective for all transactions entered into by
the Company in fiscal 1998. SOP 97-2 requires, among other things, that revenue
should be recognized when there is persuasive evidence of an existing
arrangement, delivery has occurred, the fees charged are fixed or determinable
and collectibility is probable. Additionally, SOP 97-2 provides that for those
arrangements which consist of multiple elements such as services, software,
software upgrades, enhancements and post-contract support, the fees charged must
be allocated to each element of the arrangement based upon vendor-specific
objective evidence of fair value, which is to be determined based upon the price
charged when the element is sold separately or the price for the element
established by management with relevant authority. The Company currently is
continuing to evaluate the impact that SOP 97-2 will have on license revenue
transactions entered into subsequent to January 31, 1998. Based on the Company's
reading and interpretation of SOP 97-2, the Company believes that SOP 97-2 will
not have a material impact on future operating results. However, detailed
implementation guidelines for this standard have not been issued. Once issued,
such detailed implementation guidelines could result in changes in the Company's
current revenue recognition practices, and such changes could be material to the
Company's revenues and earnings.
 
    In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 131, "Disclosures about Segments of an
Enterprise and Related Information" ("FASB 131"), which supersedes existing
accounting standards related to disclosure of operating segment information
beginning in fiscal 1998. Although the Company currently operates in only one
industry segment, the Company is in the process of evaluating the impact this
new standard will have on the Company's financial statement disclosures in
fiscal 1998. The adoption of FASB 131 will have no impact on the Company's
consolidated results of operations, financial position or cash flows and any
effect will be limited to the presentation of its Consolidated Financial
Statements.

INDUSTRY BACKGROUND
 
    The banking industry is one of the nation's largest industries, with
aggregate annual revenues of nearly $250 billion. In recent years, the industry
has undergone significant change, and today's banking environment is
characterized by intense competition, continuing consolidation, changing
regulations and rapid technological innovation. In addition to increased
competition within the banking industry, banks are encountering significant
competition from insurance companies, brokerage houses and other financial
institutions, all of which are expanding to provide services that were once
within the exclusive domain of banks. While banks historically have focused on
reducing their operating expenses to remain competitive, they are today
increasingly focusing on developing new sources of revenue growth, automating
operations to increase efficiencies and outsourcing commodity-like banking
functions to sustain market value growth. To this end, banks are expending
significant resources, both internally and through outsourcing arrangements.
Information technology expenditures by the industry in 1997 on paper-based
payment systems and financial and risk management systems alone are estimated to
have been approximately $1.0 billion and $2.3 billion, respectively, of which
approximately 59% and 51% were paid to third parties.
 
    CONSOLIDATION
 
    Over the past several years, the banking industry has experienced
substantial consolidation as banks have sought to gain a competitive advantage
by acquiring other banks. This consolidation is driven by a continuing effort to
increase revenues through a larger customer base, achieve efficiencies of scale
associated with increased operating size and enhance customer service through a
nationwide presence and consequent broader geographic reach. This trend has
resulted in a decrease in the number of banks, but an increase in the number of
banks with assets of $5 billion or more. As they grow by acquisition, these
banks require improved operational processes and technological applications that
increase efficiencies in order to recapture acquisition premiums paid. In the
face of this consolidation trend, banks are under considerable pressure to
maximize their public market valuations to enhance the attractiveness of their
acquisition currency, provide a credible defense to unsolicited offers and
increase returns to shareholders.
 
                                       27
<PAGE>
    REGULATORY CHANGE
 
    Currently, the banking industry is characterized by continuing regulatory
changes. Regulations in certain areas, such as interstate banking operations,
have been relaxed while regulations in other areas, such as payment systems,
have become more restrictive. These changes have presented banks with both
challenges and opportunities to improve their operations and achieve competitive
advantages. For instance, over the past several years changes in regulations
have required banks to provide their depositors with accelerated credit on
deposited checks, which has increased the risk of bank loss if the deposited
checks are returned unpaid after the depositor has withdrawn the funds. A 1995
study estimated that banks absorbed $850 million of losses due to check fraud.
Banks have responded by implementing expedited check processing, presentment and
return item processing systems not only to reduce such losses, but also to gain
added revenue and generate further efficiencies. Revisions to regulations also
have permitted interstate banking, which allows bank holding companies to own
banks in multiple states under a single charter and, consequently, to capture
the operating and structural efficiencies that such expanded operations make
possible. In addition, deregulation in certain sectors of the banking industry
has led to increased competition for banks from insurance companies, brokerage
houses and other financial institutions in areas of business which were
previously the exclusive domain of banks.
 
    TECHNOLOGICAL INNOVATION
 
    Rapid technological innovation is creating new means for participants in the
banking industry to gain competitive advantages, and this development has
increased customers' expectations. Increasingly, customers are requiring that
their banks provide a broader scope of banking services quickly and easily
through automated teller machines ("ATMs"), by telephone or over the Internet.
The banking industry has witnessed an exponential growth in distributed banking,
including Internet banking, with more than 2,000 banks having launched Web sites
and more than 16% of United States households estimated to be banking via the
Internet by the year 2000. Additionally, technological development has provided
banks with the potential for numerous operational enhancements. For instance,
technology currently allows for the electronic storage of images of documents
and instruments, including checks, and the ability to recall the data quickly
and to utilize the data at multiple locations simultaneously. Technology also
currently enables banks to optimize their earning assets by reducing their
reserve requirements. Furthermore, technological developments are fueling
industry-wide advancements, such as the electronification of the check payment
process. According to industry sources, in 1996, over 60 billion paper checks
were used, of which electronic check payment presentment ("ECP") accounted for
approximately 3%. However, electronification of the check payment system has
been gaining increasing acceptance as an efficient and viable solution for
eliminating the time-consuming and expensive paper shuffle.
 
    INDUSTRY CHALLENGES
 
    In order to compete effectively in this dynamic environment, banks often
must identify effective and innovative solutions to address their unique
requirements and re-design, and in some cases completely replace, their
operational systems. Effective development and implementation of these solutions
is technically challenging, time-consuming and expensive, and banks often are
faced with a choice between building internal, custom solutions or purchasing
third-party offerings. The development of internal solutions necessarily
involves either re-deploying already stretched resources or acquiring new
resources that increase fixed costs, while typically resulting in isolated,
departmental solutions. Traditional third-party solutions often have their own
shortcomings. Some third-party providers only offer analysis and consultation
regarding a bank's operations, while others only provide specific software
applications resulting in a piecemeal approach to solutions development. By
using multiple providers, banks face increased costs, more complex
implementation and delayed realization of benefits. In addition, traditional
third-party solutions typically are not designed to the banking industry's
unique requirements and are often inflexible, requiring banks to conform their
work processes to available systems. The situation is exacerbated by the fact
that effective solutions cannot be developed in isolation, given the
increasingly interdependent nature of bank-to-bank operations. Consequently,
banks are in need of a third party, familiar with the banking industry, to
provide integrated consulting services and technological applications.

THE CARREKER-ANTINORI SOLUTION
 
    Designed to address the unique requirements of the banking industry,
Carreker-Antinori's solutions enable banks to increase revenues, reduce costs
and enhance delivery of customer services. These solutions combine consulting
services and technological applications in such areas as liquidity management,
payment processing, deposit taking, fraud prevention, customer service and cash
management services. In delivering its solutions, Carreker-Antinori: (i) gathers
and analyzes information about a customer's operations, markets and external
environments; (ii) identifies opportunities for revenue enhancement, cost
minimization and other efficiency generating solutions; (iii) develops and
proposes tailored solutions, which typically include one or more of the
Company's software applications; (iv) designs a business case to justify
investment in the solutions; (v) builds project consensus among senior
management; and (vi) provides implementation and maintenance services.
Carreker-Antinori's solutions are differentiated by the following
characteristics:
 
    INDUSTRY-SPECIFIC CONSULTING EXPERTISE.  The Company's consultants, managers
and employees, many of whom are former bankers, include experts in complex bank
operations. Carreker-Antinori provides services to approximately two-thirds of
the largest 100 bank holding companies. The Company believes that its expertise
and its in-depth experience have allowed it to develop the most advanced
consulting services and technological applications for the banking industry.
 
    ADVANCED TECHNOLOGY.  Carreker-Antinori incorporates the latest
technological developments in client/server systems and protocols to produce
software applications that are scaleable, functional and able to interface with
a bank's legacy systems. In addition, the Company's participation in various
interbank organizations enables the Company to stay at the forefront of
technological innovations in the industry.
 
    INTEGRATED APPROACH.  Carreker-Antinori combines its consulting expertise
and proprietary technology to serve as a single-source provider of
fully-integrated, end-to-end solutions that address the critical needs of banks.
This approach sets the Company apart from providers of partial solutions that
require banks to seek costly additional expertise or implementation services to
attain a complete solution. By offering integrated solutions, the Company
achieves more rapid identification and implementation of solutions than would a
piecemeal approach.
 
    REDUCED CUSTOMER RISK.  The Company's solutions reduce investment risk by
increasing revenues or reducing costs in a relatively short period of time. In
addition, in appropriate circumstances, the Company value-prices certain of its
solutions, whereby it receives a percentage of the amount of additional revenues
or reduced costs achieved by the customer. These arrangements allow banks to
fund their investments in the Company's solutions with the benefits derived from
their implementation.
 
    BROAD ARRAY OF SERVICES AND TECHNOLOGY.  The Company believes that its
offerings of yield management, payment systems and related bank operations
solutions are the broadest in the banking industry. By offering a broad set of
complementary solutions, the Company is able to provide a bank with an expert
solution targeted to a narrow area of a bank's operations or to address a broad
range of a bank's operational requirements. The Company believes that by
offering a wide variety of solutions, it enhances the value that is offered to
its customers.
 
                                       29
<PAGE>
STRATEGY
 
    The Company's objective is to be the leading provider of yield management,
payment systems, payment electronification and enabling technologies solutions
to the banking industry, and to continue to serve in a leadership role in
transitioning the check payment system from paper to electronic formats. Key
elements of the Company's strategy include the following:
 
    ADVANCE POSITION AS INDUSTRY INNOVATOR.  Carreker-Antinori intends to
maintain its consulting and technology leadership position in the banking
industry by anticipating and responding to evolving industry needs and creating
consulting services and technological applications that address these needs.
Through its industry contacts and customer interaction, the Company plans to
identify new methods for converting leading-edge technologies and ideas into
practical banking solutions. The Company's leadership position is enhanced by
the role it plays in ECCHO and PSN, which enables it to be an infrastructure
development partner to the banking industry as it transitions the check payment
system from paper to electronic formats.
 
    PURSUE STRATEGIC ALLIANCES AND ACQUISITIONS.  The Company seeks to form
alliances with large service providers or acquire smaller companies whose
solutions, when combined with those of the Company, provide incremental
value-added benefits to banks. The Company has implemented this strategy through
its acquisition of ASI, its strategic alliance with Visa and IBM Global Services
in forming PSN and its recent alliance with Fiserv, Inc., UPS Worldwide
Logistics and National Processing Company in forming INFITEQ. The Company
believes that strategic alliances and acquisitions will further enable the
Company to combine its own solutions with those of complementary businesses,
provide it with strong opportunities to expand its line of banking solutions,
increase its customer base or pursue new growth platforms.
 
    LEVERAGE MARKET POSITION TO EXPAND CUSTOMER BASE.  The Company seeks to
increase its customer base by leveraging its strong relationships with Tier I
and Tier II Banks to market its solutions to other Tier II Banks and selected
smaller banks and other financial institutions. The Company also intends to
leverage its existing technological applications by marketing them to smaller
banks that do not require significant customization or implementation services.
Additionally, the Company plans to leverage its leadership position in the
United States market to pursue international customers, particularly banks
elsewhere in North America and in Europe. To this end, the Company recently has
provided solutions internationally to Barclays Bank and National Westminster
Bank, as well as to four of the largest Canadian banks through several service
companies owned by these banks. Furthermore, as non-bank financial institutions
aggressively continue to expand their markets to include related financial
services, the Company is identifying new opportunities to market its solutions
to these institutions.
 
    BUILD LONG-TERM RELATIONSHIPS.  By focusing on long-term customer
relationships where the Company can identify and offer a continual stream of
value-added solutions, the Company intends to increase its repeat business with
existing customers. Through its long-term customer relationships, the Company
plans to continue focusing on the generation of significant year-to-year
revenues, which typically produce higher gross profit margins as the Company is
able to deliver value-added solutions to existing customers without incurring
many of the start-up costs associated with the development of new relationships.
 
    INCREASE USE OF HIGH-MARGIN PRICING ARRANGEMENTS.  Carreker-Antinori will
continue to share in the value that its solutions create for customers by
expanding the use of pricing methods and negotiated arrangements to generate
recurring and high-margin revenues. The Company will seek to increase the use of
value pricing for solutions in appropriate circumstances where increased
revenues or reduced costs resulting from such solutions can be readily projected
or measured. In addition, the Company intends to expand its practice of
structuring license fees for software-based solutions according to the number of
transactions processed with the solutions, which will increase its recurring
revenues and smooth period-to-period revenues.

                                 ANALYSIS SYSTEM, that simplify the processing of certain customer deposits,
                                 facilitate float processing and enable a bank to increase its competitiveness by
                                 extending teller window hours.
  RISK MANAGEMENT                Reduces risk of loss from the check payment process as a result of operational
                                 failures, check fraud and litigation. The solutions incorporate software
                                 applications, including ON-US FRAUD and TRANSIT FRAUD, that identify potentially
                                 fraudulent checks.
 
PAYMENT ELECTRONIFICATION        Facilitates the capture of the benefits from the electronification of the check
                                 payment process. The solutions incorporate software applications, including
                                 SMARTNOTES, TNOTES and CNOTES, that reduce the risk of loss at a number of points
                                 in the check payment process.

YIELD MANAGEMENT
 
    The Company's Yield Management solutions utilize Carreker-Antinori's
in-depth banking expertise and history of innovation to produce increased
revenues for banks in a compressed time frame through improved operational
workflows, pricing structures and liquidity and cash management. The Yield
Management solutions generally consist of three practices: revenue enhancement,
liquidity management and cash management.
 
    REVENUE ENHANCEMENT
 
    The revenue enhancement practice identifies opportunities to increase a
bank's revenues quickly and recommends operational practices to capitalize on
these opportunities. In this practice, the Company analyzes a bank's records and
interviews bank representatives to obtain information regarding a bank's retail
and commercial business, markets, products, pricing policies, workflow practices
and operating procedures. This analysis typically focuses on several functional
areas, including check, loan, deposit and trust operations, deposit and loan
product management, finance and accounting. With this information, the Company
is able to recommend changes in fee structures, operational processes and other
procedures to increase a bank's revenues.
 
    LIQUIDITY MANAGEMENT
 
    The liquidity management practice enables a bank to increase its revenues by
minimizing the amount of non-earning assets that, under applicable regulations,
the bank is obligated to maintain as a reserve against deposit balances. Banks
typically satisfy their reserve requirement by maintaining interest-free
balances at the Federal Reserve Bank and as cash in vaults, branches and ATMs.
By minimizing the level of reserves the bank is required to maintain, the
liquidity management practice enables the bank to re-deploy funds maintained in
interest free balances at the Federal Reserve Bank to more productive uses.
Additionally, this practice assists banks in identifying cash-on-hand that is
surplus to normal operating requirements and reserve requirements so that such
surplus may be re-deployed in earning assets. The Company's RESERVELINK and
RESERVELINK PLUS applications minimize a bank's required reserves by
automatically sweeping daily balances in consumer and commercial accounts from
transaction accounts, which are subject to a 10% reserve requirement, to
non-transaction accounts, which have no reserve requirement. THE ANALYSIS
ADVANTAGE application allows a bank, if it so desires, to share the benefits
from reduced reserves with its commercial customers. In addition, the Company's
CASHFORECASTER, ATM CASHFORECASTER and CASHTRACKER software applications are
designed to identify surplus cash in a bank's branches and ATMs, which
information can then be used to reduce a bank's cash inventory.
 
    CASH MANAGEMENT
 
    The cash management practice enhances the revenues that certain large banks
derive from providing their institutional customers with cash management
services, such as check clearing, lockbox and money transfer services. In this
practice, the Company reviews the profitability, quality of delivery and overall
business strategy of a bank's cash management lines of business and benchmarks
the bank's performance against other industry participants. Following such a
review, the Company proposes and implements specific adjustments relating to
business strategies, market segmentation, product offerings and pricing policies
to improve the financial performance of the bank's cash management business
line.
 
PAYMENT SYSTEMS
 
    The Payment Systems solutions assist banks in reducing check-processing
costs through procedural and technological improvements that support internal
growth and acquisitions, standardize transactional processing and reduce risk of
loss. The Company's Payment Systems solutions enable banks to manage their check
processing operations to function more efficiently and effectively at reduced
costs without compromising customer service. The Payment Systems solutions
generally consist of three practices: consolidation and best practices, float
management and risk management.
 
                                       32
<PAGE>
    CONSOLIDATION AND BEST PRACTICES
 
    The consolidation and best practices practice reduces bank operating costs
in the area of check processing by consolidating check-processing centers,
streamlining check-process flows and reducing personnel to achieve economies of
scale, better management control, more standardized operations and improved
customer service. This practice also uses industry benchmarks to assure that a
bank's check-processing operations are utilizing the industry's most advanced
procedures. The consolidation and best practices practice has been used in a
variety of contexts that require streamlined check-processing operations,
including reconfiguring multi-state operations into a single operation,
collapsing multi-state banking charters into a single state charter, and
re-engineering "back-office" operations through the application of technology.
The consolidation and best practices practice offers technology applications
that focus on different areas of check processing, including customer service
and research and adjustments. The Company's technology applications that focus
on customer service, INNOVASION and SYNAPSE, enable a bank to obtain
electronically information needed internally by the bank or for customer
requests that require a copy of a check or other documentation, such as a
statement of account. Technology applications focused on adjustments and
research allow banks to respond to inquiries about checks that are stored in the
bank's archives.
 
    FLOAT MANAGEMENT
 
    The Company's float management practice focuses on a bank's check-processing
procedures and increases a bank's investable funds by optimizing bank float
profitability through improved check collection, efficient check-processing
workflow and float allocation and pricing. As a result of the implementation of
float management practices, a bank can reduce the float and related costs that
the bank incurs, increase the float allocated to the bank's customers, decrease
the bank's non-earning assets, improve the bank's check-processing workflow,
increase the bank's profitability and improve the bank's management reporting.
The float management practice consists generally of conducting float audits and
performing reviews and analyses of check-processing workflow, float management
organization, structure and reporting, check clearing and market segmentation.
The float management practice offers software applications that focus on
different approaches to optimizing a bank's float. The Company's technology
applications, such as FLOAT PRICING SYSTEM and FLOAT ANALYSIS SYSTEM, assist
banks in taking maximum advantage of float by selectively pricing availability
of funds of deposited checks to customers, measuring float profitability by
customer, and generating detailed check clearing end-point data. The Company
also offers technology applications, such as BRANCH ITEM TRUNCATION and DEPOSIT
MANAGER, that simplify the processing of customer deposits containing five items
or less and enable banks to become more competitive by extending teller window
hours while still meeting "back-office" processing deadlines.
 
    RISK MANAGEMENT
 
    The risk management practice assists banks in identifying and reducing the
risk of loss from the check payment process as a result of operational failures,
check fraud and litigation. The Company provides risk management reviews and
training and offers implementation and support of its risk management technology
applications. The Company also offers "expert opinion" services for litigation
support. The Company's risk management technology applications consist of an
application for deposited checks drawn by the bank's customer and an application
for deposited checks drawn on other banks. The application for checks drawn by
the bank's customer, ON-US FRAUD, detects potential fraud both at the teller
station and in the bank's "back-office" using a set of bank-defined detection
rules, such as duplicate check numbers, out-of-range check numbers, out-of-range
amount and inconsistent account activity. The technology application for checks
drawn on other banks and deposited with the customer bank, TRANSIT FRAUD,
detects deposit fraud by evaluating each deposited item and account against a
series of bank-defined detection rules to identify those items that have a high
probability of being fraudulent. This technology application also lists
"suspects" in a report so that bank personnel can exercise their judgment on
whether to allow a depositor to withdraw funds against the deposited item or
account.
 
                                       33
<PAGE>
PAYMENT ELECTRONIFICATION
 
    The Company's Payment Electronification solutions enable banks to capture
the benefits from the conversion of paper checks to electronic items. These
benefits, estimated by ECCHO to be between $2 billion and $3 billion for the
banking industry as a whole, arise in the near term from the earlier electronic
presentment and collection of checks deposited at one bank and drawn on another,
the reduced risk of loss from earlier electronic identification of checks that
have been or are likely to be returned unpaid, new sources of fee revenue from a
bank's institutional customers who stand to benefit from additional services
made possible by the electronification of checks, and in the longer term, from
the reduced costs associated with the truncation of paper checks at the bank of
first deposit. The Company's Payment Electronification solutions incorporate a
number of technology applications, such as CHECKLINK, that allow banks to
electronically present checks drawn on other banks and receiving banks to post
these checks to their books from the electronic transmission in advance of
receipt of the paper item, which increases the receiving bank's investable funds
as customers replenish the balances in their accounts earlier than they
otherwise would. Additionally, the Company offers a suite of technology
applications, such as SMARTNOTES, TNOTES and CNOTES, that reduce the risk of
loss from returned checks and fraudulent checks by enabling early electronic
communication with respect to these items between banks, between banks and their
customers, and between banks and third parties that furnish such information to
the retailing industry.
 
ENABLING TECHNOLOGIES
 
    The Enabling Technologies solutions provide services and products that
assist in the deployment of advanced technologies, while enabling the rapid
realization of benefits from these technologies, such as higher revenues,
reduced costs and heightened customer service. The current Enabling Technologies
solutions consist generally of four practices: electronic commerce, Year 2000,
image systems and integration services.
 
    ELECTRONIC COMMERCE
 
    The electronic commerce practice provides electronic commerce solutions to
banks that lack current on-line transactional capabilities. The Company's
electronic commerce solutions are designed to enable banks to attract and retain
larger numbers of customers, expand their geographic reach and create a lower
cost transaction processing platform. In the electronic commerce practice, the
Company assists in the development and execution of the bank's electronic
commerce strategy, the design of the electronic commerce transaction processing
platform and the procurement of appropriate technologies.
 
    YEAR 2000
 
    The Company's Year 2000 practice assists banks in determining whether their
systems will be able to manage and manipulate data in the context of the
transition of the dates from 1999 to 2000 without functional or data abnormality
and without inaccurate results related to such dates. In this practice, the
Company tests a bank's computer-dependent systems and infrastructure to assure
that they are able to make the transfer to the year 2000 both independently and
in concert with other interrelated systems. The Company also partners with third
parties that provide additional resources to address the Year 2000 problem. By
combining the Company's expertise with the resources of these partners,
Carreker-Antinori is able to provide banks with a comprehensive solution to
their Year 2000 problems.
 
    IMAGE SYSTEMS
 
    The image system deployment practice assists banks in increasing
"back-office" productivity through the use of image technologies. In many of a
bank's areas of operation, the use of an electronically stored image that can be
recalled quickly from a database and used in several places simultaneously
greatly streamlines a bank's operational processes. In its image system
deployment practice, the Company capitalizes on its industry leadership and
technological expertise to identify potential changes that image system
deployment can make to a bank's current workflow.
 
                                       34
<PAGE>
    INTEGRATION SERVICES
 
    The integration services practice assists banks in aligning their technology
and systems with their work processes, information needs, business
infrastructure and long-term strategic goals. In the integration services
practice, the Company provides banks with business process modeling, as well as
process simulation that incorporates the solutions proposed by the Company. The
Company also combines prototype client/server systems with mainframe legacy
systems and assists with architecture design and systems development.
Additionally, the Company implements operational processes and assists in
training bank personnel to realize the benefits of the Company's proposals.
 
MANAGEMENT SERVICES
 
    The Company provides management services to three banking organizations:
ECCHO, PSN and INFITEQ. The Company provides all of ECCHO's and PSN's non-legal
management services, which include administration, research and development,
industry representation and public relations. For INFITEQ, the Company is
responsible for customer service, quality assurance, recruiting additional
service providers, billing, marketing, sales, integrating products and
technology and acting as the organization's general manager (subject to the
supervision, direction and approval of the board of managers of INFITEQ). See
"--Strategic Banking Initiatives."
 
CUSTOMERS AND MARKETS
 
    A substantial majority of the Company's revenues are generated from
contracts with Tier I Banks (bank holding companies with assets over $50
billion) and Tier II Banks (bank holding companies and independent banks with
assets of between $5 billion and $50 billion). The Company's customers include
95% of Tier I Banks, including Fleet Financial Group, Inc., NationsBank
Corporation, Norwest Corporation and SunTrust Banks, Inc. In fiscal 1997, Fleet
Financial Group, Inc. and Norwest Corporation accounted for approximately 15%
and 14% of the Company's revenues, respectively. See "Risk Factors-- Customer
Concentration." The Company's customers include approximately 60% of Tier II
Banks, including Comerica Incorporated, Firstar Corporation, Huntington
Bancshares and Summit Service Corporation. The Company also targets smaller bank
holding companies and independent banks with assets of between $550 million and
$5 billion. Smaller bank customers include California Federal Savings Bank,
Mechanics Bank and U.S. Trust Company. The Company believes that the smaller
bank market affords it an opportunity for growth. See "--Strategy--Leverage
Market Position to Expand Customer Base" and "Risk Factors--Dependence on
Banking Industry."
 
    The Company enters into numerous types of engagements with customers. The
needs of each customer are unique, and Carreker-Antinori seeks to provide those
specific solutions that most effectively address a customer's needs. A model
engagement is set forth below.
 
MODEL ENGAGEMENT
 
    In a model engagement, the Company would conduct its due diligence review of
a bank's operations within a short time span of six-to-eight weeks to identify
opportunities that would enhance the bank's revenues and reduce the bank's
expenses. Upon identification of these opportunities and agreement by the bank,
Carreker-Antinori would implement certain of its yield management solutions
(revenue enhancement and liquidity management), and certain of its payment
systems solutions (float management and risk management), to rapidly generate
enhanced revenues and cost reductions for the bank. These solutions often
incorporate technology applications, such as RESERVELINK, FLOAT PRICING SYSTEM,
FLOAT ANALYSIS SYSTEM, ON-US FRAUD and TRANSIT FRAUD, and are designed to enable
the bank to recover its investment in a shorter time frame than would be the
case with competing alternatives.
 
    Upon the bank realizing the near-term benefits of the solutions that
previously were implemented, the Company would work with the bank to install
additional solutions that may require a longer period of time
 
                                       35
<PAGE>
to implement. These solutions include services from the liquidity management
practice and consolidation and best practices practice, as well as
implementation of software applications, such as RESERVELINK PLUS, CASHTRACKER,
CASHFORECASTER, INNOVASION and SYNAPSE, to improve the bank's "back-office"
operations.
 
    As the bank realizes further revenue enhancements, cost reductions and
customer service improvements from these solutions, the Company would work with
the bank to provide additional services and technology applications that further
improve the operational efficiency of the bank and generate new sources of
revenue. These solutions would include consulting services and technology
applications from the payment electronification practice and from certain of its
enabling technologies practices (electronic commerce, Year 2000, image systems
and integration services).
 
SALES AND MARKETING
 
    The Company has developed strong relationships with many senior bank
executives as a result of its delivery of effective solutions to Tier I and Tier
II Banks for 20 years. In addition, Carreker-Antinori's leadership position
within the industry enables it to develop relationships with senior banking
executives of its prospective customers. The Company has found that an important
element of its success has been its ability to maintain relationships with
banking executives as they are elevated to senior positions in a consolidating
banking industry. The Company believes that the strength of its customer
relationships contributes significantly to sales and marketing efforts. The
Company has seven Account Relationship Managers ("ARMs") who are responsible for
managing the Company's day-to-day relationships with its customers. Their
responsibilities include identifying customers' needs and assisting the
Company's practice managers in presenting their solutions and concluding sales.
The Company's ARMs work closely with the Company's executive officers who serve
as Executive Relationship Managers ("ERMs") to the Company's customers. The
Company also employs Software Account Managers ("SAMs") who are familiar with
the Company's technology and who participate in opportunities to sell
technology-based solutions.
 
    The Company derives a significant portion of its business through customer
referrals and repeat business. In addition, the Company markets its services
through a variety of media, including: the Company's Web site, direct mail,
"user" conferences conducted by Carreker-Antinori exclusively for its customers,
speaking engagements, participation in industry conferences and trade shows,
publication of "white papers" related to specific aspects of the Company's
services, customer newsletters, and informational listings in trade journals.
The Company employs a marketing staff of seven persons, including graphics
designers, writers, administrative coordinators and a Web master.
 
STRATEGIC BANKING INITIATIVES
 
    The Company provides management services to ECCHO and PSN, each of which is
playing an instrumental role in the electronification of the check payment
process. In addition, the Company is a co-founder of INFITEQ, which provides
outsourcing services to the banking industry.
 
ECCHO
 
    ECCHO, Electronic Check Clearing House Organization, is a not-for-profit
rules and standards organization whose bank members hold approximately 80% of
the deposits held by the top 100 banks in the United States. This organization
is committed to promoting the transition of payment systems from paper to
electronic formats. ECCHO intends to accomplish these goals by aligning the
relationships among various participants in the banking industry to promote the
rapid acceptance and implementation of electronic check applications.
 
PSN
 
    PSN, Payment Systems Network, Inc., is a corporation owned by 19 bank
holding companies representing more than 180 banks in all 50 states, which
collectively hold over 40% of bank deposits in the
 
                                       36
<PAGE>
United States. PSN strives to support the initiatives of ECCHO by creating
products that will generate new revenue streams and reduce fraud losses and
processing expenses for banks and provide incentive to banks to take incremental
steps towards the utilization of electronic check processing. PSN's products
incorporate a number of applications developed by the Company, such as
SMARTNOTES, TNOTES and CNOTES. See "--Products and Services--Payment
Electronification."
 
INFITEQ
 
    INFITEQ, a joint venture among the Company, UPS Worldwide Logistics,
National Processing Company and Fiserv, Inc., is a single-source provider of
specialized outsourcing services to the banking industry for transaction
processing, information management, electronic commerce and image technology.
INFITEQ integrates leading providers of specific services into a broad cafeteria
of service offerings, which allows banks to economically expand the number of
services offered to customers by outsourcing these additional services. INFITEQ
offers to banks the expertise of UPS Worldwide Logistics in package delivery and
ground/air logistics, National Processing Company in the retail lockbox business
and image-enabled remote capture, Fiserv, Inc. in its compute/capture centers
and its deposit processing system, and the Company in payment systems, cash
management, system integration, data warehousing, Year 2000 solutions and
electronic commerce. INFITEQ markets its broad array of services as a complement
to the services that the bank performs itself.
 
SOLUTIONS DEVELOPMENT
 
    The Company seeks to maintain its position as a leading innovator in the
banking industry by converting leading-edge technologies and ideas into
practical banking solutions. The Company's relationships with its customers
provide it with opportunities to identify additional bank needs. The Company's
solutions development activities focus on prototyping promising applications,
test marketing new products, developing sales strategies and coordinating
distribution and on-going maintenance for each of the Company's solutions.
 
    The Company frequently receives customer requests for new services and/or
software, develops solutions in response to these requests and historically has
been able to recoup some or all of its development costs from these customers.
In addition to customer-funded solutions development, the Company has invested
significant amounts in solutions development, including expenditures of
$906,000, $1.2 million and $3.4 million for software development in fiscal 1995,
1996 and 1997, respectively. Further, some of the Company's key product
introductions have resulted from the adaptation for a wider market of customized
solutions that were originally developed by customers for their internal use. In
exchange for either a one-time payment and/or on-going royalties, the Company is
often able to obtain the right to develop, enhance and market such products.
 
    The Company believes that its leadership role in and interaction with the
banking industry through ECCHO, PSN and INFITEQ uniquely position it to identify
and develop interbank solutions that have bilateral or multilateral banking
industry applications. The Company believes that its management of these
organizations provides further opportunities to recognize and respond to the
changing needs of the banking industry.
 
TECHNOLOGY
 
    The Company designs its software products to incorporate the latest
developments in open systems architecture and protocols to provide maximum
scaleability and functionality and to interface with a bank's legacy systems.
The Company's core proprietary technologies, for both its client/server software
products and mainframe software products, are primarily directed at using a
standard set of components, drivers and application interfaces so that the
Company's software products are constructed from reusable components which are
linked together in a tool-set fashion.
 
                                       37
<PAGE>
    Most of the Company's client/server software products are based upon the
Company's proprietary SYNAPSE architecture. The SYNAPSE architecture is a
component framework that provides reusable building blocks or object-oriented
components for developing multi-tiered highly distributed software applications.
The SYNAPSE architecture is intended to provide a straightforward framework for
defining and implementing the core, or low level, components used in
constructing software products. The current core components of the SYNAPSE
architecture include DAS persistent object, trace/audit component and viewer,
messaging infrastructure, network management functionality, work flow engine,
folder manager, distribution manager, DAS client and data archive server.
 
    The Company has adopted the IBM System Application Architecture for
developing its interactive screen designs for its mainframe products and for
interactions with other systems, such as client/server products. The Company's
mainframe software products have been evolving toward a standard set of core
processing components, drivers and exit points and are more fully leveraging
published standard application programming interfaces. As a result, the Company
can employ reusable components to create new utility modules and link them
together in a tool-set fashion, much like objects in object-oriented
programming.
 
    The Company has a number of software products that either fall within the
client/server or the batch-oriented file sharing categories. Many of the newer
software products are developed to operate with an OS/2 and/or Windows NT
operating system. Most of the Company's mainframe software products are written
in COBOL. The Company has several software products that operate on two or more
of these operating systems. For example, the Company's INNOVASION software
application operates with the OS/2 operating system, while the Company's DAS
software application, a substantially similar product programmed in C++,
operates with the Windows NT operating system.
 
    The Company develops its technology both internally and, in certain
strategically beneficial situations, with third-party preferred developers that
can offer an expertise within a core competency. For example, currently
Carreker-Antinori is working on features of its CASHFORECASTER software
application with a third party that has a core competency in developing advanced
forecasting engines based on synthetic algorithms, including neural net
technology and annealing techniques.
 
COMPETITION
 
    The Company competes with third-party providers of services and software
products to the banking industry, including firms providing consulting services,
such as Andersen Consulting, Electronic Data Systems Corporation and KPMG Peat
Marwick LLP, and software companies, such as Earnings Performance Group, Inc.,
Pegasystems Inc., Sterling Software, Inc. and Transoft International, Inc. The
Company believes that it competes based on a number of factors, including: (i)
scope of solutions provided; (ii) industry expertise; (iii) access to decision
makers within banks; (iv) ease and speed of solutions implementation; (v)
quality of solutions; and (vi) price. While many of the Company's competitors
are better equipped to compete with the Company in certain of these areas, the
Company believes that it is uniquely qualified to compete effectively in all of
these areas.
 
    In addition to competing with a variety of third parties, the Company
experiences competition from its customers and potential customers. From time to
time, such customers develop, implement and maintain their own services and
applications for revenue enhancement, cost reductions or enhanced customer
service, rather than purchasing services and related software products from
third parties. As a result, the Company must continually educate existing and
prospective customers about the advantages of purchasing its services and
products. In addition, customers or potential customers could enter into
strategic relationships with one or more of the Company's competitors to
develop, market and sell competing services or products. See "Risk
Factors--Competition."
 
                                       38
<PAGE>
GOVERNMENT REGULATION
 
    The Company's primary customers are banks. Although the services currently
offered by the Company have not been subject to any material industry-specific
government regulation, the banking industry is heavily regulated. The Company's
services and products must allow banking customers to comply with all applicable
regulations, and, as a result, the Company must understand the intricacies and
application of many government regulations. The regulations most applicable to
the Company's provision of solutions to banks include requirements establishing
minimum reserve requirements, governing funds availability and the collection
and return of checks, and establishing rights, liabilities and responsibilities
of parties in electronic funds transfers. For example, the Company's RESERVELINK
and RESERVELINK PLUS software and related consulting services assist banks with
minimizing their reserves while complying with federal reserve requirements. In
addition, the expedited availability and check return requirements imposed by
funds availability regulations have increased fraud opportunities dramatically,
and the Company's risk management and float management services address this
concern while complying with such regulations. See "Risk Factors--Governmental
Regulation."
 
PROPRIETARY RIGHTS
 
    The Company relies upon a combination of patent, copyright, trademark and
trade secret laws, including the use of confidentiality agreements with
employees, independent contractors and third parties and physical security
devices to protect its proprietary technology and information. The Company
primarily has relied on common law rights to protect the use of its name,
technology and brands. The Company has a number of issued patents and one
registered trademark and has filed applications for additional patents and
trademarks in the United States. The Company vigorously defends its proprietary
rights.
 
    The Company presently enters into invention assignment and confidentiality
agreements with its employees and independent contractors and confidentiality
agreements with certain customers. The Company also limits access to the source
codes for its software and other proprietary information. Further, the Company's
software will not operate with computers which have not been synchronized with
the Company's equipment. The Company believes that due to the rapid pace of
innovation within the software industry, factors such as the technological and
creative expertise of its personnel, the quality of its solutions, the quality
of its technical support and training services, and the frequency of release of
technology enhancements are more important to establishing and maintaining a
technology leadership position than the various legal protections available for
the Company's technology.
 
    The Company is not aware that it is infringing any proprietary rights of
third parties. The Company relies upon certain software that it licenses from
third parties, including software that is integrated with the Company's
internally developed software and used in its solutions to perform key
functions. See "Risk Factors--Dependence on Proprietary Technology; Risk of
Infringement."
 
EMPLOYEES
 
    The Company had 208 employees as of January 31, 1998, with 66 persons
providing consulting services, 79 persons in the technical group, 23 persons
performing sales and marketing, customer relations and business development
functions and 40 persons performing corporate, finance and administrative
functions. The Company has no unionized employees. The Company believes that its
employee relations are good.
 
INDEPENDENT CONTRACTORS
 
    The Company provides consulting services and develops software in part
through the use of independent contractors who are not employees of the Company.
As of January 31, 1998, the Company used 28 independent contractors to provide
consulting services, 26 of whom work from their homes using self-
 
                                       39
<PAGE>
owned equipment. Many of these contractors are former bank executives, and the
Company believes that their experience in the banking industry uniquely enables
them to provide consulting services to the Company's customers. In addition, as
of January 31, 1998, the Company had 32 independent contractors who assisted in
the development of technology. These technology contractors spend a majority of
their time performing software development in the Company's offices; however,
from time to time these contractors travel with Company personnel and work
directly with the Company's customers. See "Risk Factors--Use of Independent
Contractors."
 
FACILITIES
 
    The Company's principal executive office is a leased facility with
approximately 32,000 square feet of space in Dallas, Texas. The lease agreement
for this space expires in May 1999. The Company also leases approximately 21,000
square feet in Atlanta, Georgia pursuant to a lease agreement which expires in
August 2002. The Company believes that its existing facilities are well
maintained and in good operating condition and are adequate for its present and
anticipated levels of operations.

    end (January 31, 1998) of $8.90 per share, as determined by the Company's
    Board of Directors, less the exercise price payable for such shares.

LONG TERM INCENTIVE PLAN
 
    SCOPE.  The Company has a 1994 Long Term Incentive Plan which was originally
adopted in 1994, and will be amended and restated prior to the completion of the
offering (as amended and restated, the "Long Term Incentive Plan"). The Long
Term Incentive Plan is designed to attract and retain qualified and competent
employees, non-employee directors and consultants, and to provide additional
equity-based incentives to employees, non-employee directors and consultants of
the Company. Awards under the Long Term Incentive Plan may be granted in the
form of incentive stock options, non-qualified options and restricted shares, as
determined by the Board of Directors at the time of grant and subject to the
applicable provisions of the Internal Revenue Code of 1986, as amended (the
"Code"). The Board of Directors may delegate any or all of its discretion under
the Long Term Incentive Plan to the Compensation Committee. Although the Long
Term Incentive Plan itself is of indefinite duration, no awards of incentive
stock options may be made under the Long Term Incentive Plan after October 6,
2004.
 
    SHARES RESERVED UNDER THE LONG TERM INCENTIVE PLAN.  The Company has
reserved for issuance under the Long Term Incentive Plan 5,500,000 shares of
Common Stock, of which 1,621,882 shares previously have been issued pursuant to
options that have been exercised, 2,408,783 shares are subject to currently
outstanding options, 84,700 shares of restricted stock have been issued and
1,384,635 shares of Common Stock are reserved for future awards. If an award
made under the Long Term Incentive Plan expires, terminates or is forfeited,
cancelled or settled in cash, without issuance of shares of Common Stock covered
by the award, those shares will be available for future awards under the Long
Term Incentive Plan. Commencing on February 1, 1999, and for each year
thereafter, the number of shares of Common Stock available for awards under the
Long Term Incentive Plan will be increased by a number of shares equal to 2% of
the number of shares of Common Stock outstanding as of the effective date of the
amended and restated Long Term Incentive Plan.
 
    ELIGIBILITY.  Persons eligible to participate in the Long Term Incentive
Plan include all employees of the Company or any subsidiary of the Company, all
non-employee directors and all consultants for the Company. Awards of incentive
stock options under the Long Term Incentive Plan may be made only to employees
of the Company or any subsidiary.
 
                                       46
<PAGE>
    ADMINISTRATION.  The Long Term Incentive Plan is administered by the Board
of Directors, unless the Board of Directors delegates its authority to the
Compensation Committee. The Board of Directors has the authority to grant
options and restricted shares under the Long Term Incentive Plan and to
determine the vesting schedule and the exercise price of the options, and the
restrictions and terms thereof. The Board of Directors also has full power and
authority to construe, interpret and administer the Long Term Incentive Plan.
 
    OPTION EXERCISE PRICE.  The exercise price per share for the Common Stock
issued pursuant to incentive stock options under the Long Term Incentive Plan
shall be no less than 100% of the fair market value on the date the option is
granted. The exercise price per share for non-qualified stock options under the
Long Term Incentive Plan may be determined by the Board or Committee, but may
not be less than the par value of the shares.
 
    ADJUSTMENTS, TERMINATIONS AND AMENDMENT.  In the event of any change in the
Company's capitalization, including any stock split, reverse stock split, stock
dividend, spinoff, combination or reclassification of the Common Stock, or any
other increase or decrease in the number of issued shares of Common Stock
effected without receipt of consideration by the Company, appropriate
adjustments will be made to the number of shares available under the Long Term
Incentive Plan as well as the price per share and/or number of shares covered by
any outstanding option or restricted stock award.
 
    The Long Term Incentive Plan may be suspended, terminated, altered or
amended in any way by the Board of Directors, provided that stockholder approval
of any plan amendment will be required to the extent necessary and desirable to
comply with applicable provisions of the Securities Exchange Act of 1934 (the
"Exchange Act"), the Code or other legal requirements. No suspension,
termination, alteration or amendment of the Long Term Incentive Plan may alter
or impair any option or restricted stock award previously made under the Long
Term Incentive Plan.
 
    BUSINESS COMBINATIONS.  Unless provision is otherwise made in an award, or
by the terms of the agreement with respect to a business combination, in the
event of a change in control of the Company (as defined), then, with respect to
each option or restricted share outstanding immediately prior to the
consummation of such transaction and without the necessity of any action by the
Compensation Committee, all outstanding stock options and restricted stock shall
terminate or be forfeited, provided that the holders of any options may exercise
such awards to the extent then vested immediately prior to any such event.
 
DIRECTOR STOCK OPTION PLAN
 
    The Company's Board of Directors will approve the Carreker-Antinori, Inc.
Director Stock Option Plan prior to the completion of the offering (the
"Director Plan"). The purpose of the Director Plan is to encourage ownership in
the Company by outside directors whose continued services are considered
essential to the Company's further progress, thereby providing them with an
additional incentive to continue as directors of the Company. The Director Plan
will terminate on January 31, 2013.
 
    PRINCIPAL FEATURES OF THE DIRECTOR PLAN.  The Director Plan provides that
eligible directors of the Company may elect to receive options to purchase
Common Stock in lieu of all or a portion of their annual director's retainer and
various attendance fees. Only directors of the Company who are not employees of
the Company are eligible to participate in the Director Plan.
 
    Options will be granted automatically on the first trading day in any fiscal
quarter (the "Grant Date") to any eligible director who, prior to the Grant
Date, files with the committee administering the Director Plan an election to
receive a stock option in lieu of 25%, 50%, 75% or all of his retainer and
attendance fees to be earned in the period from the Grant Date to the end of the
fiscal year. The per share option price (the "Option Price") under the Director
Plan is equal to 50% of the fair market value of the Common Stock (the "Market
Value") on the Grant Date. "Market Value" is the fair market value of the
 
                                       47
<PAGE>
Common Stock at the close of business on the relevant Grant Date, as reported on
the Nasdaq National Market. Elections will be deemed made for each succeeding
fiscal year, and options will be automatically granted on the first trading day
in each succeeding fiscal year, unless the director notifies the Company of the
cancellation of the election prior to the first day of the fiscal year.
 
    The number of option shares granted to an eligible director will be
determined by a formula which provides that each director will receive an option
equal to the nearest number of whole shares equivalent to the Deferred Retainer
and Fees divided by the Option Price. "Deferred Retainer and Fees" are the
amounts the director would have been entitled to receive for serving as a
director and attending all regularly scheduled meetings of the Board of
Directors and its Committees during the remainder of the fiscal year following
the Grant Date but for the election described above.
 
    As an example, assuming a Market Value of the Common Stock equal to the
assumed initial public offering price of $11.00 per share, if a director elected
to participate in the Director Plan at a 100% level for fiscal year 1999, he
would have received an option for 1,818 shares. This amount is calculated by
dividing (i) the director's deferred retainer ($5,000) plus anticipated
attendance fees of $5,000 (assuming no committee meeting attendance fees) by
(ii) 50% of $11.00, the applicable Market Value for the Common Stock.
 
    Generally, no option may be exercised prior to the first anniversary of the
date the option was granted. However, an option will become fully exercisable
upon the retirement of the director because of age, disability or death. In
addition, upon a merger or other business combination involving the Company, an
option will become fully exercisable unless the Company is the surviving
corporation in such merger or business combination or provision is made for the
continuance and assumption of the option. No option may be exercised after the
expiration of 15 years from the date the option was granted. If the optionee
ceases to be a director before an option granted under the Director Plan becomes
exercisable or is absent from a regularly scheduled meeting, the option shall
terminate as to a pro rata portion of the shares subject to the option, based
upon the number of Board and committee meetings attended during the relevant
period.
 
    Unless limited by the option agreement pursuant to which an option is
granted, the option price may be paid upon exercise of an option by delivery of
shares of Common Stock, cash or a combination of cash and Common Stock. The
shares so delivered will be valued as of the exercise date.
 
    Options granted under the Director Plan are transferable by the director by
will or the laws of descent and distribution and to members of the director's
immediate family. After a director's death, the option is exercisable by the
director's designee or, in the absence of a designation, the director's legal
representative.
 
    SHARES RESERVED UNDER THE DIRECTOR PLAN.  A total of 100,000 shares of
Common Stock may be issued pursuant to the Director Plan. The Company plans to
register the shares under the Securities Act. Upon the exercise of an option,
the Company may issue authorized but unissued shares or reissue shares
previously repurchased by or on behalf of the Company.
 
    ADMINISTRATION.  The Director Plan is administered by the Company's
Compensation Committee.
 
    ADJUSTMENTS, TERMINATIONS AND AMENDMENT.  The Compensation Committee has the
power to modify, extend or renew outstanding options and authorize the grant of
new options in substitution therefor, provided that any such action may not have
the effect of altering or impairing any rights or obligations of any option
previously granted without the consent of the optionee.
 
    STOCK OPTIONS PREVIOUSLY AWARDED TO NON-EMPLOYEE DIRECTORS.  Prior to its
adoption of the Director Plan, the Company granted options to certain of its
current and former non-employee directors. Messrs. James D. Carreker, Fischer
and Lee, as well as two former directors, each hold 55,263 options, all of which
are fully vested.
 
                                       48
<PAGE>
PROFIT SHARING PLAN
 
    The Company maintains a Profit Sharing Incentive Plan (the "Profit Sharing
Plan") administered by the Compensation Committee in which substantially all
employees of the Company are eligible to participate. Under the terms of the
Profit Sharing Plan, each year the Compensation Committee reviews the Company's
actual financial performance in the preceding year compared to certain financial
performance objectives established at the outset of such year. If the Company
exceeded these financial objectives, then a bonus pool is established, and is
allocated among the various operating and corporate divisions of the Company
based upon the Compensation Committee's assessment of the gross contribution
made by each division to the Company's overall performance. Awards are allocated
among specific employees within each division on the basis of the employee's
individual performance and contribution to the overall goals of his or her
division and of the Company. The Compensation Committee seeks input from Company
management in making awards. Awards under the Profit Sharing Plan are made in
the form of cash bonuses and stock-based compensation pursuant the Company's
Long Term Incentive Plan, with at least 50% of awards granted to senior
management consisting of stock-based compensation. An employee may at his or her
election substitute any cash award for an equivalent stock-based compensation
award. Messrs. John D. Carreker, Jr. and Antinori removed themselves from
consideration for awards under the Profit Sharing Plan in fiscal 1997, but all
other executive officers received awards in that year.
 
EMPLOYMENT AGREEMENTS
 
    JOHN D. CARREKER, JR.  The Company is a party to an employment agreement
with Mr. Carreker with a term extending through January 31, 1999. The agreement
may be renewed by Mr. Carreker for an additional one-year term upon six months'
prior written notice to the Company. The agreement provides that Mr. Carreker
will receive a base annual salary of not less than $450,000 and will be eligible
to receive bonuses as determined by the Board of Directors in its sole
discretion. The agreement may be terminated at any time by the Board of
Directors, with or without cause, and may be terminated during the first two
years of the agreement by Mr. Carreker if the Company is in material breach of
the agreement. Upon termination of the agreement by Mr. Carreker due to a breach
on the part of the Company or by the Company without cause, Mr. Carreker will be
entitled to receive, on the Company's regular payroll dates and less required
withholdings, his salary at the current rate for the remaining term of the
agreement.
 
    RONALD R. ANTINORI.  The Company is a party to an employment agreement with
Mr. Antinori with a term extending through January 31, 1999. The agreement
provides that Mr. Antinori will receive a base annual salary during the first
year of not less than $350,000. Mr. Antinori will be entitled to a salary
increase in the second year of the agreement: (i) if the Board of Directors, in
its sole discretion, so determines or (ii) if Mr. Carreker receives a salary
increase in the second year of his contract, Mr. Antinori will be entitled to
receive the same salary increase on a dollar-for-dollar basis. Mr. Antinori will
not receive a bonus for the fiscal year ending January 31, 1998 unless Mr.
Carreker receives a bonus for such fiscal year, in which event their bonuses for
such fiscal year shall be in the same proportion as are their salaries for such
year. If and to the extent the Board of Directors establishes a bonus pool for
the fiscal year ending January 31, 1999, then Mr. Antinori will be entitled to
participate in the same, with the amount of his bonus to be determined based
upon the bonus paid to Mr. Carreker in respect of such fiscal year. In such
event, Messrs. Antinori and Carreker's bonuses shall be in the same proportion
as are their salaries. In determining any bonus for Mr. Antinori, credit will be
given to the Company contributions to his profit-sharing account, if any. The
agreement may be terminated at any time by the Board of Directors, with or
without cause, and may be terminated by Mr. Antinori if the Company is in
material breach of the agreement. Upon termination by Mr. Antinori due to a
breach on the part of the Company or by the Company without cause, Mr. Antinori
will be entitled to receive, on the Company's regular payroll dates and less
required withholdings, his salary at the current rate for the remaining term of
the agreement.
 
    OTHER EXECUTIVES.  The Company is a party to employment agreements with
Messrs. Linting, Brown and Lewis. The agreement with Mr. Linting has a term
extending through December 1999 and the
 
                                       49
<PAGE>
agreements with Messrs. Brown and Lewis have a term extending through March
2001. Under the agreements, Messrs. Linting, Brown and Lewis will receive an
annual base salary of not less than $350,000, $240,000 and $300,000,
respectively, and each is entitled to a bonus of seventy percent of his annual
base salary on terms no less favorable than those applicable to other high-level
officers of the Company in each year of the applicable agreement if the Board of
Directors, in its sole discretion, so determines. The agreement with Mr. Linting
also provides for the Company to reimburse him in the aggregate amount of up to
$48,000 per year for rent and other living expenses. The agreements may be
terminated at any time by the Company, with or without cause, and may be
terminated by the executive if the Company is in material breach of the
applicable agreement. Upon termination by the executive due to a breach on the
part of the Company or by the Company without cause, the executive will be
entitled to receive, on the Company's regular payroll dates and less required
withholdings, his salary at the current rate for the remaining term of the
agreement.
 
    The Company also intends to enter into an employment agreement with Mr. Gage
prior to the completion of the offering.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS
 
    As permitted by the Delaware General Corporation Law, the Company's
Certificate of Incorporation provides that no director of the Company will be
personally liable to the Company or its stockholders for monetary damages for
breach of his or her fiduciary duty as a director, except for: (i) any breach of
the director's duty of loyalty to the corporation or its stockholders; (ii) acts
or omissions not in good faith or that involve intentional misconduct or a
knowing violation of the law; (iii) unlawful payments of dividends or unlawful
stock repurchases or redemptions; or (iv) any transaction from which the
director derived an improper personal benefit. The Company's Certificate of
Incorporation and Bylaws provide for the Company's indemnification of its
officers and directors to the fullest extent permitted by the Delaware General
Corporation Law. The Company is also a party to an indemnification agreement
with each of its directors. In addition, the Company intends to maintain
directors' and officers' liability insurance. There is no pending litigation or
proceeding involving a director, officer or employee of the Company for which
indemnification is sought, nor is the Company aware of any threatened litigation
that may result in claims for indemnification.

                              CERTAIN TRANSACTIONS
 
THE REINCORPORATION
 
    Concurrently with the offering, the Company will change its state of
incorporation from Texas to Delaware (the "Reincorporation"). The
Reincorporation will be effected by merging Carreker-Antinori, Inc., a Texas
corporation ("C-A Texas"), into a newly organized, wholly-owned, Delaware
subsidiary that will be the surviving corporation (the "Company"). The Plan and
Agreement of Merger relating to the Reincorporation provides for: (i) the
conversion of each outstanding share of common stock of C-A Texas into 7.70
shares of Common Stock of the Company; (ii) the conversion of all options and
rights to acquire shares of common stock of C-A Texas under its various benefit
plans into options and rights to acquire shares of Common Stock of the Company
on a basis consistent with the Common Stock conversion ratio; and (iii) the
substitution of the charter and bylaws of the Company for those of C-A Texas.
The Reincorporation will not result in any material change in the business,
assets or financial position of C-A Texas, or in the persons who constitute its
Board of Directors or management.
 
MERGER WITH ANTINORI SOFTWARE, INC.
 
    On January 31, 1997, a wholly-owned subsidiary of the Company merged with
and into ASI, with the result that ASI became a wholly-owned subsidiary of the
Company (the "Merger"). Pursuant to the Merger, the shareholders of ASI received
3,962,528 shares of Common Stock. Of this amount, Ronald R. Antinori, Vice
Chairman of the Board nominee and Chief Technology Officer of the Company,
received 3,526,654 shares of Common Stock and Susan Antinori, his wife, received
396,250 shares of Common Stock of the Company. Following resolution of certain
issues relating to the Merger, Mr. Antinori returned 176,122 shares of Common
Stock to the Company for cancellation and is obligated to return an additional
140,910 shares on or before March 31, 1998. In addition, Ms. Antinori returned
19,789 shares and another former shareholder of ASI returned 1,979 shares. The
return of these shares was intended to effectuate a post-merger adjustment to
reflect the relative values of the Company and ASI at the time of the Merger. In
connection with the Merger, Messrs. Carreker and Antinori and the Company
entered into a Shareholders Agreement which granted certain registration rights
to Messrs. Carreker and Antinori and certain former ASI shareholders. See
"Description of Capital Stock--Registration Rights." Also, Messrs. Carreker and
Antinori entered into certain Employment Agreements with the Company. See
"Management--Employment Agreements."
 
CONSULTING SERVICES
 
    David K. Sias, a director nominee of the Company, provided special
consulting services to the Company in connection with the Merger. In addition to
a monthly consulting fee of $4,167, the Board of Directors of the Company
authorized the payment of a special fee of $200,000 to Mr. Sias to compensate
him for his time and efforts spent on behalf of the Company in connection with
the Merger. The Company paid consulting fees to Mr. Sias in the aggregate
amounts of $71,682, $64,310 and $36,178 in fiscal 1997, 1996 and 1995,
respectively. The Company and Mr. Sias expect to enter into a new arrangement
that will provide for compensation to be paid to Mr. Sias following the offering
that reflects both his services as a director of and consultant to the Company.
 
SALE OF SHARES TO SAIC
 
    On October 10, 1996, Science Applications International Corporation ("SAIC")
acquired 774,967 shares of the Company's Common Stock for $2.0 million and
entered into a Shareholder Agreement with the Company and John D. Carreker, Jr.
Pursuant to the Shareholder Agreement, SAIC was entitled to one representative
on the Board of Directors of the Company. Larry J. Peck, Sector Vice President
and Manager, Technology Solutions Sector, of SAIC was elected to the Board of
Directors. In addition, SAIC was granted an option to require the Company to
repurchase its shares of Common Stock pursuant to the
 
                                       51
<PAGE>
Shareholder Agreement. The Shareholder Agreement terminates upon completion of
the offering. The Company and SAIC also entered into a three-year, non-exclusive
Strategic Alliance Agreement providing for joint efforts to offer services,
products and technology to customers.
 
SALE OF SHARES TO CROW FAMILY PARTNERSHIP, L.P.
 
    On January 10, 1997, the Crow Family Partnership, L.P. ("Crow") acquired
269,500 shares of the Company's Common Stock for $834,050. In connection with
such purchase, Crow was granted certain registration rights with respect to
shares of Common Stock held by it. See "Description of Capital Stock--
Registration Rights." James D. Carreker, a director nominee of the Company,
serves as a director of Crow Family, Inc., the general partner of Crow.
 
PROVISION OF MANAGEMENT SERVICES TO ECCHO, PSN AND INFITEQ
 
    The Company provides management services to three organizations, ECCHO, PSN
and INFITEQ (See "Business--Strategic Banking Initiatives"). David Walker,
Senior Vice President of the Company, serves as Executive Director of ECCHO. For
the fiscal years ended January 31, 1998, 1997 and 1996, the Company recognized
revenues from ECCHO for its management services in the amount of approximately
$994,000, $866,000 and $696,000, respectively. John D. Carreker, Jr., Chairman
of the Board and Chief Executive Officer of the Company, serves as a director of
PSN. In the fiscal years ended January 31, 1998, 1997 and 1996, the Company
recognized revenues from PSN for its management services in the amounts of $1.4
million, $1.3 million and $1.3 million, respectively. John D. Carreker, Jr.
serves as Chairman of the Board of INFITEQ, and John D. Carreker, III, Senior
Vice President of the Company and the son of John D. Carreker, Jr., serves as
Executive Director of INFITEQ. Under a ten-year agreement entered into on
January 1998 with three other service providers in INFITEQ, the Company will
receive a monthly fee of $45,000 plus expenses for an initial period, and
thereafter, a fee calculated on a percentage of the charges from the service
providers to the banks, as well as certain other amounts. See "Management's
Discussion of Financial Condition and Results of Operations--Liquidity and
Capital Resources."
 
STOCK OPTION LOAN PROGRAM
 
    A substantial number of the Company's employees hold options to purchase
shares of Common Stock that will terminate if unexercised contemporaneously with
the offering. The Company intends to offer a stock option loan program (the
"Loan Program") to these employees to loan to them, on a full recourse basis,
the purchase price required to exercise their options immediately prior to
consummation of the offering. The interest rate on such loans will be
approximately 5.3% per annum, with interest payments due annually and the
principal due upon maturity (two years from the date of the loans). The shares
of Common Stock received by an option holder upon exercise of his or her options
will be pledged as collateral to secure the loan and each option holder will
agree not to transfer such shares until the original vesting date of the options
to which such shares relate (subject to certain exceptions permitting earlier
sales of the related shares). In the event that all eligible option holders
elect to fully participate in the Loan Program, the Company will permit
employees to exercise their options by executing promissory notes in the
aggregate approximate amount of $3,022,373, of which $18,599, $85,702, $48,860,
$427,760 and $120,463 will represent loans to Messrs. Brown, Davis, Eubanks,
Gage and Lewis, respectively. For purposes of determining the number of shares
of Common Stock currently outstanding, this Prospectus assumes that all options
that terminate if unexercised contemporaneously with the offering will be
exercised and the related shares of Common Stock will be issued (1,159,882
shares of Common Stock in the aggregate).

                       PRINCIPAL AND SELLING STOCKHOLDERS
 
    The following table sets forth certain information regarding the beneficial
ownership of the Company's Common Stock and as adjusted to reflect the sale of
shares of Common Stock in the offering, by: (i) each person known by the Company
to own beneficially more than 5% of the outstanding Common Stock; (ii) each of
the Company's directors; (iii) each of the Named Executive Officers; (iv) all

<PAGE>
                          DESCRIPTION OF CAPITAL STOCK
 
    The Company's authorized capital stock consists of 100,000,000 shares of
Common Stock, $.01 par value per share ("Common Stock"), and 2,000,000 shares of
Preferred Stock, $.01 par value per share ("Preferred Stock"), issuable in
series. There will be 13,092,664 shares of Common Stock outstanding immediately
prior to consummation of the offering, held of record by 55 stockholders. No
shares of Preferred Stock are outstanding.
 
COMMON STOCK
 
    The holders of Common Stock are entitled to one vote for each share held of
record on all matters submitted to a vote of the stockholders. The holders of
Common Stock are not entitled to cumulative voting rights with respect to the
election of directors, and as a consequence, minority stockholders will not be
able to elect directors on the basis of their votes alone. Subject to
preferences that may be applicable to any then outstanding shares of Preferred
Stock, holders of Common Stock are entitled to receive ratably such dividends as
may be declared by the Board of Directors out of funds legally available
therefor. See "Dividend Policy." In the event of a liquidation, dissolution or
winding up of the Company, holders of the Common Stock are entitled to share
ratably in all assets remaining after payment of liabilities and the liquidation
preference of any then outstanding Preferred Stock. Holders of Common Stock have
no preemptive, conversion or other rights to subscribe for additional securities
of the Company. There are no redemption or sinking fund provisions applicable to
the Common Stock. All outstanding shares of Common Stock are, and all shares of
Common Stock to be outstanding upon completion of the offering will be, validly
issued, fully paid and nonassessable.
 
PREFERRED STOCK
 
    The Board of Directors has the authority, without further action by the
stockholders, to issue up to 2,000,000 shares of Preferred Stock in one or more
series and to fix the rights, preferences, privileges and restrictions thereof,
including dividend rights, conversion rights, voting rights, terms of
redemption, liquidation preferences, sinking fund terms and the number of shares
constituting any series or the designation of such series, without any further
vote or action by stockholders. The issuance of Preferred Stock could adversely
affect the voting power of holders of Common Stock and the likelihood that such
holders will receive dividend payments and payments upon liquidation and could
have the effect of delaying, deferring or preventing a change in control of the
Company. The Company has no present plan to issue any shares of Preferred Stock.
 
DELAWARE ANTI-TAKEOVER LAW AND CERTAIN CHARTER PROVISIONS
 
    DELAWARE ANTI-TAKEOVER STATUTE.  The Company is subject to the provisions of
Section 203 of the Delaware General Corporation Law, an anti-takeover law.
Subject to certain exceptions, the statute prohibits a publicly held Delaware
corporation from engaging in a "business combination" with an "interested
stockholder" for a period of three years after the date of the transaction in
which the person became an interested stockholder, unless the interested
stockholder attained such status with the approval of the Board of Directors,
the business combination is approved in a prescribed manner or certain other
conditions are satisfied. For purposes of Section 203, a "business combination"
includes a merger, asset sale or other transaction resulting in a financial
benefit to the interested stockholder, and an "interested stockholder" is a
person who, together with affiliates and associates, owns (or within three years
prior, did own) 15% or more of the corporation's voting stock.
 
    CERTIFICATE OF INCORPORATION.  The Company's Certificate of Incorporation
(the "Certificate") provides: (i) for the authorization of the Board of
Directors to issue, without further action by the stockholders, up to 2,000,000
shares of Preferred Stock in one or more series and to fix the rights,
preferences, privileges and restrictions thereof; (ii) that any action required
or permitted to be taken by stockholders of the Company must be effected at a
duly called annual or special meeting of the stockholders and may not be
effected by a consent in writing; (iii) that special meetings of stockholders of
the Company may be called only by the Chairman of the Board, the Chief Executive
Officer or a majority
 
                                       55
<PAGE>
of the members of the Board of Directors; (iv) for a classified Board of
Directors; (v) that vacancies on the Board of Directors, including newly created
directorships, can be filled only by a majority of the directors then in office,
and (vi) that directors of the Company may be removed only for cause and only by
the affirmative vote of holders of at least two-thirds of the outstanding shares
of voting stock, voting together as a single class.
 
    These provisions are intended to enhance the likelihood of continuity and
stability in the composition of the Board of Directors and in the policies
formulated by the Board of Directors and to discourage certain types of
transactions that may involve an actual or threatened change of control of the
Company. These provisions are designed to reduce the vulnerability of the
Company to an unsolicited proposal for a takeover of the Company that does not
contemplate the acquisition of all of its outstanding shares, or an unsolicited
proposal for the restructuring or sale of all or part of the Company. Such
provisions, however, could discourage potential acquisition proposals and could
delay or prevent a change in control of the Company. Such provisions may also
have the effect of preventing changes in the management of the Company. See
"Risk Factors--Anti-Takeover Matters."
 
LIMITATIONS ON DIRECTOR LIABILITY
 
    The Certificate provides that, to the fullest extent permitted by the
Delaware General Corporation Law, as the same exists or as may hereafter be
amended, directors of the Company will not be liable to the Company or its
stockholders for monetary damages for breach of fiduciary duty as a director.
 
REGISTRATION RIGHTS
 
    Pursuant to an agreement among the Company, Ronald R. Antinori, Susan
Antinori (Mr. Antinori's wife), Michael Israel and Lawrence D. Duckworth (the
"ASI Shareholders"), and John D. Carreker, Jr. (together with the ASI
Shareholders, the "Shareholders"), the Shareholders are entitled to certain
rights with respect to the registration of shares of Common Stock under the
Securities Act. If the Company proposes to register any shares of Common Stock
under the Securities Act for its own account for cash, the Shareholders are
entitled to notice of such registration and entitled, subject to certain
limitations, to include shares of their Common Stock therein. The registration
rights of each of the Shareholders continue until such time as the Shareholder
can sell shares of Common Stock pursuant to Rule 144(k) under the Securities
Act. Additionally, at any time from and after one year after the completion of
the offering, the Shareholders holding not less than 50%, on a fully-diluted
basis, of the capital stock of the Company are entitled to certain demand
registration rights pursuant to which they may require the Company to file a
registration statement under the Securities Act; provided, however, that the
amount of shares to be offered for sale in the demand registration must have a
fair market value of $10 million or more. The Company is not obligated to effect
more than four demand registrations. The Company is required to use its best
efforts to effect such registrations. Generally, the Company is required to bear
all registration and selling expenses incurred in connection with any such
registrations. The rights are subject to certain conditions and limitations,
among them the right of the underwriters of an offering to limit the number of
shares included in such registrations.
 
    Pursuant to an agreement between the Company and Crow, Crow also has certain
registration rights. If any other stockholder of the Company exercises
contractual registration rights, Crow is entitled to notice of such registration
and is entitled, subject to certain limitations, to include shares of its Common
Stock therein. Generally, the Company is required to bear all registration and
selling expenses incurred in connection with such registrations. The rights are
subject to certain conditions and limitations, among them the right of the
underwriters of an offering to limit the number of shares included in such
registrations. The Crow registration rights terminate at such time as its shares
may be sold under Rule 144 of the Securities Act.
 
TRADING MARKET, TRANSFER AGENT AND REGISTRAR
 
    The Company has applied for quotation of the Common Stock on the Nasdaq
National Market under the symbol CANI. The Transfer Agent and Registrar for the
Common Stock is ChaseMellon Shareholder Services, L.L.C.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
    Upon completion of the offering, the Company will have an aggregate of
16,742,664 shares of Common Stock outstanding. Of these shares, all of the
shares sold in the offering will be freely transferable without restriction or
limitation under the Securities Act, except for any shares purchased by
"affiliates" or persons deemed to be acting as "underwriters" (as such terms are
defined under the Securities Act) of the Company. The remaining 11,642,664
shares constitute "restricted shares" within the meaning of Rule 144, and the
resale of such shares is restricted for one year from the date they were
acquired. Of these "restricted securities," 10,697,792 shares have been held for
the required one-year period and will be freely tradeable upon completion of the
offering, subject to the 180-day lock-up period described below. The remaining
944,872 "restricted securities" have not been held for the requisite one-year
period and, upon completion of the offering, will be tradeable after the
expiration of the lock-up period and subject to the volume and price limitations
of Rule 144. The holders of 8,443,448 shares have certain rights to have shares
registered in the future under the Securities Act pursuant to the terms of
agreements between such holders and the Company. See "Description of Capital
Stock--Registration Rights."
 
    In general, under Rule 144, as currently in effect, a person (or persons
whose shares are required to be aggregated) who has beneficially owned, for at
least one year, shares of Common Stock that have not been registered under the
Securities Act or that were acquired from an "affiliate" of the Company is
entitled to sell within any three-month period the number of shares of Common
Stock which does not exceed the greater of one percent of the number of then
outstanding shares or the average weekly reported trading volume during the four
calendar weeks preceding the sale. Sales under Rule 144 are also subject to
certain notice and manner of sale requirements and to the availability of
current public information about the Company and must be made in unsolicited
brokers' transactions or to a market maker. A person (or persons whose shares
are aggregated) who is not an "affiliate" of the Company under the Securities
Act during the three months preceding a sale and who has beneficially owned such
shares for at least two years is entitled to sell such shares under Rule 144
without regard to the volume, notice, information and manner of sale provisions
of such rule. Rule 144 does not require the same person to have held the
securities for the applicable periods.
 
    Any employee, officer or director of or consultant to the Company who
purchased or was awarded shares or options to purchase shares pursuant to a
written compensatory plan or contract is entitled to rely on the resale
provisions of Rule 701 under the Securities Act, which permits affiliates and
non-affiliates to sell such shares without having to comply with the holding
period restrictions of Rule 144, in each case commencing 90 days after the date
of this Prospectus. In addition, non-affiliates may sell such shares without
complying with the public information, volume and notice provisions of Rule 144.
Rule 701 is available for option holders of the Company as to all shares issued
pursuant to the exercise of options granted prior to the offering.
 
    The Company, its executive officers, directors and principal and other
stockholders, who will hold, collectively, 5,749,764 shares of Common Stock
after the offering, have agreed not to offer or sell any shares of Common Stock
for a period of 180 days following the date of this Prospectus without the prior
written consent of BancAmerica Robertson Stephens, except that the Company may
issue shares of Common Stock in connection with acquisitions and pursuant to the
exercise of stock options described in this Prospectus. On the date of this
Prospectus, the Company had outstanding options to purchase 2,408,783 shares of
Common Stock, of which 1,825,061 shares are not subject to lock-up agreements
and may be eligible for sale until at least 90 days following the date of this
Prospectus.
 
    After the offering, the Company intends to file a registration statement on
Form S-8 to register all of the shares of Common Stock reserved for issuance
pursuant to the Long Term Incentive Plan and the Director Plan. Accordingly,
shares issued upon exercise of such options will be freely tradeable by holders
who are not affiliates of the Company and, subject to the volume and other
limitations of Rule 144, by holders who are affiliates of the Company.
 
    Prior to the offering, there has been no market for the Common Stock. No
predictions can be made of the effect, if any, that market sales of shares of
Common Stock or the availability of such shares for sale
 
                                       57
<PAGE>
will have on the market price prevailing from time to time. Nevertheless, sales
of significant amounts of Common Stock could adversely affect the prevailing
market price of the Common Stock, as well as impair the ability of the Company
to raise capital through the issuance of additional equity securities. See "Risk
Factors--Shares Eligible for Future Sale."

    The Representatives have advised the Company and the Selling Stockholders
that the Underwriters propose to offer the shares of Common Stock to the public
at the initial public offering price set forth on the cover page of this
Prospectus and to certain dealers at such price less a concession of not in
excess of $    per share, of which $    may be reallowed to other dealers. After
the initial public offering, the public offering price, concession and
reallowance to dealers may be reduced by the Representatives. No such reduction
shall change the amount of proceeds to be received by the Company as set forth
on the cover page of this Prospectus.
 
    The Company and a Selling Stockholder have granted to the Underwriters an
option, exercisable during the 30-day period after the date of this Prospectus,
to purchase up to 62,033 and 702,967 additional shares of Common Stock,
respectively (an aggregate of 765,000 shares of Common Stock), at the initial
public offering price per share set forth on the cover page of this Prospectus.
In the event the Underwriters exercise their right to purchase less than all of
the shares of Common Stock covered by the option, then the Underwriters will
first purchase the shares held by the Selling Stockholder and will thereafter
purchase shares issued by the Company. To the extent that the Underwriters
exercise the option, each of the Underwriters will have a firm commitment to
purchase approximately the same percentage of such additional shares that the
number of shares of Common Stock to be purchased by it shown in the above table
represents as a percentage of the total number of shares offered hereby. If
purchased, such additional shares will be sold by the Underwriters on the same
terms as those on which the shares offered hereby are being sold.
 
    The Underwriting Agreement contains covenants of indemnity among the
Underwriters, the Company and the Selling Stockholders against certain civil
liabilities, including liabilities under the Securities Act and liabilities
arising from breaches of representations and warranties contained in the
Underwriting Agreement.
 
    Pursuant to the terms of lock-up agreements, the holders of 5,749,764 shares
of the Company's Common Stock have agreed, for a period of up to 180 days after
the date of this Prospectus, that, subject to certain exceptions, they will not
contract to sell or otherwise dispose of any shares of Common Stock, any options
or warrants to purchase shares of Common Stock or any securities convertible
into, or exchangeable for, shares of Common Stock, owned directly or hereafter
acquired by such holders or with respect to which they have the power of

Stephens. BancAmerica Robertson Stephens may, in its sole discretion, and at any

the lock-up agreements, subject to Rule 144.
 
    In addition, the Company has agreed that until 180 days after the date of
this Prospectus, the Company will not, without the prior written consent of
BancAmerica Robertson Stephens, subject to certain exceptions, offer, sell,
contract to sell or otherwise dispose of any shares of Common Stock, any options
or warrants to purchase any shares of Common Stock or any securities convertible
into, or exercisable or exchangeable for shares of Common Stock, other than the
Company's sale of shares in the offering, the issuance of shares of Common Stock
upon the exercise of outstanding options and the grant of options to purchase
shares of Common Stock under existing employee stock option or stock purchase
plans. Furthermore, the Company has agreed not to file any registration
statements on Form S-8 to register the shares of Common Stock reserved for
issuance under the Long Term Incentive Plan and the Director Plan until at least
180 days after the date of this Prospectus. See "Shares Eligible For Future
Sale."
 
    The Underwriters do not intend to confirm sales to any accounts over which
they exercise discretionary authority.
 
    Prior to the offering, there has been no public market for the Common Stock
of the Company. Consequently, the initial public offering price for the Common
Stock offered hereby will be determined through negotiations among the Company,
the Selling Stockholders and the Representatives. Among the factors to be
considered in such negotiations are prevailing market conditions, certain
financial information of the Company, market valuations of other companies that
the Company and the Representatives believe to be comparable to the Company,
estimates of the business potential of the Company, the present state of the
Company's development and other factors deemed relevant.
 
    The Representatives have advised the Company that, pursuant to Regulation M
under the Securities Act, certain persons participating in the offering may
engage in transactions, including stabilizing bids, syndicate covering
transactions or the imposition of penalty bids, which may have the effect of
stabilizing or maintaining the market price of the Common Stock at a level above
that which might otherwise prevail in the open market. A "stabilizing bid" is a
bid for or the purchase of the Common Stock on behalf of the Underwriters for
the purpose of fixing or maintaining the price of the Common Stock. A "syndicate
covering transaction" is the bid for or the purchase of the Common Stock on
behalf of the Underwriters to reduce a short position incurred by the
Underwriters in connection with the offering. A "penalty bid" is an arrangement
permitting the Representatives to reclaim the selling concession otherwise
accruing to an Underwriter or syndicate member in connection with the offering
if the Common Stock originally sold by such Underwriter or syndicate member is
purchased by the Representatives in a syndicate covering transaction and has
therefore not been effectively placed by such Underwriter or syndicate member.
The Representatives have advised the Company that such transactions may be
effected on the Nasdaq National Market or otherwise and, if commenced, may be
discontinued at any time.
 
                                 LEGAL MATTERS
 
    The validity of the issuance of the shares of Common Stock offered by this
Prospectus will be passed upon for the Company by Locke Purnell Rain Harrell (A
Professional Corporation), Dallas, Texas. Maurice E. Purnell, Jr., a shareholder
of Locke Purnell Rain Harrell (A Professional Corporation), is the Secretary of
the Company. Certain legal matters in connection with the offering will be
passed upon for the Underwriters by Brobeck, Phleger & Harrison LLP, Austin,
Texas.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
The Board of Directors and Stockholders
Carreker-Antinori, Inc.
 
    We have audited the accompanying consolidated balance sheets of
Carreker-Antinori, Inc. (the Company), as of January 31, 1997 and 1998, and the
related consolidated statements of operations, stockholders' equity, and cash
flows for each of the three years in the period ended January 31, 1998. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of
Carreker-Antinori, Inc., at January 31, 1997 and 1998, and the results of its
operations and its cash flows for each of the three years in the period ended
January 31, 1998, in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENT
 
1. DESCRIPTION OF BUSINESS
 
    The accompanying consolidated financial statements of Carreker-Antinori,
Inc. (the Company), include the accounts of The Carreker Group, Inc. (TCG), a
Texas corporation, and Antinori Software, Inc. (ASI), a Georgia corporation. On
January 31, 1997, ASI was merged with TCG in a transaction accounted for as a
pooling of interests (Note 3). The Company is a leading provider of yield
management, payment systems, payment electronification and enabling technologies
solutions to the banking industry. The Company's solutions include comprehensive
service offerings coupled with a broad array of state-of-the-art, proprietary
software products which have been designed to address the unique requirements of
the banking industry. These solutions improve the competitiveness of a bank's
financial performance and operations, including payment processing, deposit
processing, customer service and cash management services among others. As
described in Note 8, the Company also provides consulting and administrative
services to certain organizations.
 
    Net revenues of $3,021,000 and $4,669,000 to a major customer accounted for
16% of net revenues in each of the years ended January 31, 1996 and 1997. Net
revenues of $11,956,000 to two major customers accounted for 30% of net revenues
in the year ended January 31, 1998.
 
    In connection with the Company's initial public offering, the Company will
change its state of incorporation from Texas to Delaware (the Reincorporation).
The Reincorporation will be effected by merging Carreker-Antinori, Inc., a Texas
corporation (C-A Texas), into a newly organized, wholly-owned, Delaware
subsidiary that will be the surviving corporation and is referred to herein as
the Company. The Plan and Agreement of Merger relating to the Reincorporation
provides for: (i) the conversion of each outstanding share of Class A voting
Common Stock and Class B non-voting Common Stock of C-A Texas into 7.7 shares of
Common Stock of the Company; (ii) the conversion of all options and rights to
acquire shares of Class A and Class B Common Stock of C-A Texas under its
various benefit plans into options and rights to acquire shares of Common Stock
of the Company on a basis consistent with the Common Stock conversion ratio; and
(iii) the substitution of the charter and bylaws of the Company for those of C-A
Texas. The financial statements included herein reflect the merger and resulting
change in capitalization as all share and per share amounts have been
retroactively restated to reflect the merger.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    PRINCIPLES OF CONSOLIDATION
 
    The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiaries. All significant intercompany balances and
transactions have been eliminated in consolidation.
 
    CASH AND CASH EQUIVALENTS
 
    The Company considers all highly liquid investments with maturities of three
months or less when purchased to be cash equivalents. Cash and cash equivalents
consist primarily of demand deposit accounts and shares in a demand money market
account comprised of domestic and foreign commercial paper, certificates of
deposit and U.S. government obligations.
 
    ACCOUNTS RECEIVABLE
 
    A significant portion of the Company's business consists of providing
consulting services and licensing software to major domestic banks, which gives
rise to a concentration of credit risk in receivables. The Company performs
on-going credit evaluations of its customers' financial condition and generally
requires

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
no collateral. The Company maintains an allowance for losses based upon the
expected collectibility of all accounts receivable. Writeoffs of receivables
during the three years ended January 31, 1996, 1997 and 1998 were $97,000,
$546,000 and $368,000, respectively.
 
    Accounts receivable include unbilled amounts that represent receivables for
work performed for which billings have not been presented to the customers or
which are not contractually billable. Unbilled receivables are generally billed
and collected within one year. Accounts receivable include $2,053,000 and
$4,202,000 of unbilled receivables at January 31, 1997 and 1998, respectively.
 
    INVENTORY
 
    Inventory is stated at the lower of cost (first-in, first-out) or market and
is primarily comprised of computer hardware.
 
    PROPERTY AND EQUIPMENT
 
    Property and equipment are stated at cost. Depreciation is calculated using
the straight-line method over the estimated useful lives of the respective
assets, generally from three to five years. Leasehold improvements are amortized
using the straight-line method over the shorter of the terms of the related
leases or the respective useful lives of the assets.
 
    SOFTWARE COSTS CAPITALIZED
 
    The Company capitalizes software development costs incurred in developing a
product once technological feasibility of the product has been determined.
Software development costs capitalized also include amounts paid for purchased
software on products that have reached technological feasibility. All software
development costs capitalized are amortized using an amount determined as the
greater of: (i) the ratio that current gross revenues for a capitalized software
project bears to the total of current and future gross revenues for that project
or (ii) the straight-line method over the remaining economic life of the product
(generally three to five years). The Company recorded amortization relating to
software development costs capitalized of $595,000, $606,000 and $745,000 in the
years ended January 31, 1996, 1997 and 1998, respectively.
 
    REVENUE RECOGNITION
 
    Revenue for consulting services performed under fixed-price contracts is
recognized on a percentage-of-completion method. Revenue from these contracts is
recognized in the proportion that costs incurred bear to total estimated costs
at completion. Anticipated losses on fixed-price contracts are recognized when
estimable.
 
    Revenue generated from consulting services and under management services
contracts is recognized as services are performed. Revenue generated from
value-priced consulting services is recognized at the completion of the
contractual terms when the performance fee is agreed to by the customer and the
fee contingency has been removed.
 
    Revenue from sales of software licenses are recognized when software
products are delivered to the customer and no significant vendor obligations
remain.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    Maintenance contract revenue is recognized ratably over the term of the
related contract. Revenue from computer hardware sales is recognized upon
shipment.
 
    In connection with software license agreements entered into with certain
banks and purchase agreements with vendors under which the Company acquired
software technology used in products sold to its customers, the Company is
required to pay royalties on future sales of the software. Approximately
$123,000, $724,000 and $816,000 of royalty expense was recorded under these
agreements in the years ended January 31, 1996, 1997 and 1998, respectively.
 
    In October 1997, the Accounting Standards Executive Committee of the
American Institute of Certified Public Accountants issued Statement of Position
No. 97-2, "Software Revenue Recognition" (SOP 97-2), which supersedes Statement
of Position No. 91-1. SOP 97-2 will be effective for all transactions entered
into by the Company subsequent to January 31, 1998. The Company is continuing to
evaluate the impact that SOP 97-2 will have on license revenue transactions
entered into subsequent to January 31, 1998. Based upon the Company's reading
and interpretation of SOP 97-2, the Company believes that SOP 97-2 will not have
a material impact on future operating results. However, detailed implementation
guidelines for this standard have not been issued. Once issued, such detailed
implementation guidelines could result in changes in the Company's current
revenue recognition practices, and such changes could be material to the
Company's revenues and earnings.
 
    DEFERRED REVENUE
 
    Deferred revenue represents amounts billed to customers under terms
specified in consulting, software licensing, and maintenance contracts for which
completion of contractual terms or delivery of the software has not occurred.
 
    RESEARCH AND PRODUCT DEVELOPMENT COSTS
 
    Research and product development costs, which are not subject to Statement
of Financial Accounting Standards (SFAS) 86, "Accounting for the Cost of
Computer Software to be Sold, Leased, or Otherwise Marketed," are expensed as
incurred and relate mainly to the development of new products and the ongoing
maintenance of existing products. Research and development expenses incurred by
the Company are reported net of funding obtained under research and development
arrangements.
 
    EARNINGS PER SHARE
 
    Basic earnings per share is computed using the weighted average number of
shares of common stock outstanding during each period. Diluted earnings per
share is computed using the weighted average number of shares of common stock
outstanding during each period and common equivalent shares consisting of stock
options (using the treasury stock method).
 
    INCOME TAXES
 
    The Company accounts for income taxes under the liability method whereby
deferred income tax assets and liabilities result from temporary differences.
Temporary differences are differences between tax bases of assets and
liabilities and their reported amounts in the financial statements that will
result in taxable or deductible amounts in future years.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    STOCK-BASED COMPENSATION
 
    Compensation expense on stock options issued to employees is measured in
accordance with Accounting Principles Board Opinion 25, "Accounting for Stock
Issued to Employees" (APB 25).
 
    USE OF ESTIMATES
 
    The preparation of financial statements in accordance with generally
accepted accounting principles requires management to make certain estimates and
assumptions that affect the amounts reported in the financial statements. Actual
results could differ from these estimates.
 
    NEW ACCOUNTING STANDARD
 
    In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 131, "Disclosures about Segments of an
Enterprise and Related Information" (FASB 131), which supersedes existing
accounting standards related to disclosure of operating segment information. The
provisions of FASB 131 are effective for the Company beginning the year ended
January 31, 1999. Although the Company currently operates in one industry
segment, the Company is evaluating the potential impact of FASB 131 on its
reporting requirements.
 
3. BUSINESS COMBINATION
 
    On January 31, 1997, TCG acquired all the outstanding common shares of ASI
from the shareholders of ASI in exchange for 3,962,528 shares of TCG common
stock. Effective with the merger, the combined entity changed its legal name to
Carreker-Antinori, Inc. The transaction was accounted for as a pooling of
interests, and accordingly, the accompanying consolidated financial statements
have been restated to include among other things the financial position and
results of operations of ASI for all periods presented. On January 29, 1998, the
Company and shareholders of ASI entered into a settlement agreement under which
the ASI shareholders agreed to return 338,800 shares of Common Stock to the
Company. The settlement in shares was determined based upon the fair value of
the Company's Common Stock on the consummation date of the merger. At January
31, 1998, 197,890 shares of Common Stock had been returned to the Company and
canceled.
 
    During the year ended January 31, 1997, the Company recorded charges of
$834,220 in connection with the merger. These charges consisted of investment
banking, legal, accounting and other fees. Included in these charges are fees of
$200,000 payable to a director of the Company for consulting services performed
in connection with the merger.
 
4. CREDIT ARRANGEMENTS
 
    The Company has a revolving credit agreement (the Revolving Credit
Agreement) with a bank which extends through July 1, 1998. The maximum amount of
borrowings allowed under the Revolving Credit Agreement is $3.0 million subject
to a borrowing base calculated based on 70% of qualified accounts receivable (as
defined in the Revolving Credit Agreement). At January 31, 1998, the maximum
borrowings allowed under the Revolving Credit Agreement was $3.0 million. The
Company had no borrowings outstanding under the Revolving Credit Agreement at
January 31, 1998. Borrowings under the Revolving Credit Agreement bear interest
at the prime lending rate (8.5% at January 31, 1998) and are collateralized
against certain assets of the Company, including accounts and notes receivable,
inventory, and intangibles.

4. CREDIT ARRANGEMENTS (CONTINUED)
The Revolving Credit Agreement contains certain financial covenants and
restrictions including limitations on capital expenditures, the maintenance of
specified levels of tangible net worth and certain financial ratios. The Company
may not declare or pay any dividends (unless such dividends are payable in the
Company's stock) without obtaining prior written consent from the lender.
 
5. PROVISION FOR INCOME TAXES
 
    Prior to the merger of ASI and TCG, ASI had elected to be treated as an S
corporation for federal and state income tax purposes. As such, the taxable
income of ASI was reported to and subject to tax to its shareholders. The
provision for income taxes reported on the consolidated statement of operations
for the years ended January 31, 1996 and 1997, provides approximate federal and
state income taxes (by applying statutory income tax rates) that would have been
incurred if ASI had been subject to tax as a C corporation. The pro forma
adjustment to the tax provision amounted to $149,000 and $103,000 in the years
ended January 31, 1996 and 1997, respectively.
 
    The Company's provision for income taxes, including pro forma amounts for
the years ended January 31, 1996 and 1997, consists of the following (in
thousands):

6. COMMON STOCK
 
    In June 1996, the Company repurchased 1,427,249 shares of Common Stock,
representing all the shares held by Pacific USA Holdings Corp., for a total cash
price of $2,000,000.
 
    In October 1996, Science Applications International Corporation (SAIC)
purchased 774,967 shares of common stock for a cash purchase price of
$2,000,000. In connection with the stock purchase, the Company and SAIC entered
into a Shareholders Agreement (the Shareholders Agreement) under which SAIC was
granted: (i) the right to participate in any future offerings of common stock by
the Company so as to avoid dilution of SAIC's equity interest in the Company and
(ii) a put option which requires, if exercised, the Company to purchase any or
all shares of common stock owned by SAIC under certain conditions, as defined in
the Shareholder Agreement. The Shareholders Agreement terminates upon the
closing of a firm underwritten public offering of the Company's common stock
which has an aggregate offering price of at least $15,000,000 or a merger
between the Company and another corporation or entity that is not affiliated
with or controlled by the Company in which the Company is not the surviving
corporation in the merger. The Company has classified the common stock subject
to the put outside of stockholders' equity on the consolidated balance sheet.
The put option will terminate if the Company's initial public offering is
consummated (Note 11).
 
7. BENEFIT PLANS
 
    STOCK OPTION PLANS
 
    Effective October 7, 1994, the Company adopted the 1994 Long Term Incentive
Plan (the Long Term Incentive Plan) under which officers and employees may be
granted awards in the form of incentive stock

options, non-qualified stock options and restricted shares. The exercise price
per share for the Common Stock issued pursuant to incentive stock options under
the Long Term Incentive Plan shall be no less than 100% of the fair market value
on the date the option is granted. The exercise price per share for non-
qualified stock options under the Long Term Incentive Plan may be determined by
the Compensation Committee of the Company's Board of Directors (the Committee),
but may not be less than the par value of the shares. Options granted under the
Long Term Incentive Plan become exercisable and vest as determined by the
Committee. To date, options granted under the Long Term Incentive Plan fully
vest within two to three years from the date of grant. The term of each option
granted under the Long Term Incentive Plan shall be as the Committee determines,
but in no event shall any option have a term of longer than ten years from the
date of grant. Options may be granted pursuant to the Long Term Incentive Plan
up to October 7, 2004, unless the Board of Directors terminates the Long Term
Incentive Plan prior to such date.
 
    At January 31, 1998, the Company's employees hold options to purchase
1,159,882 shares of Common Stock which immediately vest upon consummation of the
Company's initial public offering and are required to be exercised
contemporaneously with consummation of such offering (Note 11). The Company
intends to offer a stock option loan program to provide loans to the employees,
on a full recourse basis, for the purchase price required to exercise their
options immediately prior to consummation of the offering.
 
    On January 31, 1998, the Committee issued 84,700 shares of restricted stock
to certain key employees under the Company's Long Term Incentive Plan. Holders
of restricted stock retain all rights of a stockholder, except the shares cannot
be sold until they vest. Upon employee termination, all unvested shares are
forfeited to the Company. The restricted shares vest in full on January 31,
2001. At January 31, 1998, there was deferred compensation related to the
restricted shares totaling $754,000. The deferred compensation will be charged
to expense over the vesting period.
 
    The Company has a Director Stock Option Plan (the Director Plan) under which
non-employee members of the Company's Board of Directors may be granted options
to purchase shares of the Company's Common Stock at prices determined by the
Committee. Options granted under the Director Plan expire after ten years from
the date of grant or at such earlier date as determined by the Committee and
specified in the applicable stock option agreement. Each option granted shall
become exercisable immediately or in one or more installments as determined by
the Committee and as provided in the applicable stock option agreement. All
shares issued and options granted pursuant to the Director Plan are subject to
restriction agreements.
 
    As part of an employment contract, the President of ASI granted an option to
an officer of ASI in December 1995 to purchase 396,257 equivalent shares of the
Company's Common Stock at an exercise price of $.54 per share from the President
of ASI. The exercise price was set at 25% of the fair market value on the grant
date. As a result, the Company recorded deferred compensation of $642,633 to be
expensed ratably over the vesting period. The option initially vested over a two
year period from the date of grant but fully vested in the event of a change in
control as defined in the option agreement. The option fully vested as a result
of the TCG and ASI merger effective January 31, 1997. Therefore, all remaining
deferred compensation recorded relating to this stock option grant was expensed
in the fourth quarter of 1997. The fair value of these options as determined by
the provisions of Statement of Financial Accounting Standards No. 123,
Accounting for Stock-Based Compensation (SFAS 123), was $.89 per option on the
date of grant.

    As of January 31, 1998, the Company has reserved for issuance under the Long
Term Incentive Plan 5,120,500 shares of Common Stock, of which 84,700 shares of
restricted stock have been issued, 3,953,665 shares are subject to currently
outstanding options and 1,082,135 shares of Common Stock are reserved for future
awards. In addition to shares issued under the Long Term Incentive Plan, 276,315
shares of Common Stock are subject to currently outstanding options issued to
directors. A total of 100,000 shares of Common Stock are reserved for future
issuance under the Director Plan.
 
    The Company has elected to follow APB 25 and related interpretations in
accounting for its employee stock options because, as discussed below, the
alternative fair value accounting provided for under SFAS 123 requires the use
of option valuation models that were not developed for use in valuing employee
stock options. Under APB 25, no compensation expense is recorded when the
exercise price of the Company's employee stock options equals the fair value of
the underlying stock on the date of grant. Compensation equal to the intrinsic
value of employee stock options is recorded when the exercise price of the stock
options is less than the fair value of the underlying stock on the date of
grant. Any resulting compensation is amortized to expense over the option's
vesting period. During the years ended January 31, 1996 and 1997, total
compensation expense recorded relating to employee stock options was $53,552 and

$589,081, respectively. No compensation expense relating to employee stock
options was recorded during the year ended January 31, 1998.
 
    Information regarding pro forma net income is required by SFAS 123, and has
been determined as if the Company had accounted for its employee stock options
under the fair value method of SFAS 123. The fair value of these options was
estimated at the date of grant using a Black-Scholes option pricing model with
no volatility and the following assumptions for 1996, 1997 and 1998,
respectively: weighted-average risk free interest rate of 5.92%, 6.22% and
5.95%, no dividends, and weighted average expected life of 5, 3.49 and 4.45
years.
 
    The Black Scholes option valuation model was developed for use in estimating
the fair value of traded options which have no vesting restrictions and are
fully transferable. In addition, option valuation models require the input of
highly subjective assumptions including the expected stock price volatility.
Because the Company's employee stock options have characteristics significantly
different from those of traded options, and because changes in the subjective
input assumptions can materially affect the fair value estimate, in management's
opinion, the existing models do not necessarily provide a reliable single
measure of the fair value of its employee stock options.
 
    For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting period. The Company's
pro forma information (in thousands, except per share amounts) is as follows:

    The pro forma disclosures only include the effect of options granted
subsequent to January 31, 1995. Accordingly, the pro forma information does not
reflect the pro forma effect of all previous stock option grants of the Company,
and thus is not indicative of future amounts until SFAS 123 is applied to all
outstanding stock options.

    Effective October 22, 1984, the Company established an Employee Stock
Ownership Plan (the ESOP) for the benefit of eligible employees. In February
1992, the Company contributed $650,000 to the ESOP. The ESOP used the proceeds
from the contribution to purchase 278,054 shares of the Company's Common Stock
from an officer and principal stockholder of the Company. Shares of Common Stock
acquired by the ESOP have been allocated to each employee in amounts based on
the employee's compensation (all shares have been allocated as of January 31,
1996). Compensation expense related to the ESOP is based upon the shares of
Common Stock allocated to participants and amounted to $162,500 in 1996.
Unearned ESOP compensation is reported as a reduction to Common Stock in
stockholders' equity.

7. BENEFIT PLANS (CONTINUED)
    PROFIT SHARING PLAN
 
    TCG has adopted a profit sharing plan pursuant to Section 401(k) of the
Internal Revenue Code (the Code) whereby participants may contribute a
percentage of compensation not in excess of the maximum allowed under the Code.
The plan provides for a matching contribution by TCG. Effective January 1, 1998,
employees of ASI became eligible to participate in the TCG plan. Employer
matching contributions amounted to $210,000, $304,000 and $421,000 in 1996, 1997
and 1998, respectively. TCG may make additional contributions at the discretion
of the Board of Directors. No discretionary contribution was made during 1996,
1997, or 1998. Prior to January 1, 1998, employees of ASI had a separate profit
sharing plan pursuant to Section 401(k) of the Code, whereby participants could
contribute a percentage of compensation not in excess of the maximum allowed
under the Code. Employer matching contributions are discretionary and amounted
to $135,000, $187,000 and $260,000 under the ASI plan for the years ended
January 31, 1996, 1997 and 1998, respectively.
 
    BONUS PLAN
 
    The Company pays bonuses to key employees based on Company profitability,
the extent to which individuals meet agreed-upon objectives for the year, and
executive management's discretion. The Company recorded bonus expense of
approximately $1,486,000, $2,179,000 and $1,051,000 in 1996, 1997 and 1998,
respectively.
 
8. MANAGEMENT SERVICES
 
    The Company serves as Executive Director of the Electronic Check Clearing
House Organization (ECCHO) and provides consulting and administrative services
to ECCHO, for which the Company recorded net revenues of $696,000, $866,000 and
$994,000 in 1996, 1997 and 1998, respectively. Receivables from ECCHO were
$317,000, $477,000 and $566,000 at January 31, 1996, 1997 and 1998,
respectively.
 
    The Company owns an equity interest in Payment Solutions Network, Inc. (PSN)
for which the Company has no book basis. PSN's articles of incorporation require
PSN to repurchase the Company's equity interest for $1,250,000 at a rate of
$250,000 per year over a five-year period, with the final year's payment
contingent upon the amount of operating revenue of PSN in the fifth year. The
annual repurchase of these units is subject to PSN maintaining certain cash and
net worth levels. The proceeds from the first scheduled repurchase of $250,000
was received by the Company from PSN in January 1996 and included in other
income. The scheduled 1997 and 1998 repurchase of $250,000 was not received due
to cash and net worth levels of PSN falling below the amounts stipulated in its
articles of incorporation. Additional payments, if any, to be received by the
Company from PSN in subsequent years will be recognized as other income when the
realization of such amounts is probable.
 
    To assist PSN in maintaining its liquidity, the Company and another
stockholder of PSN each advanced PSN a total of $500,000 in two increments in
August and December of the fiscal year ended January 31, 1997. The Company
believes ultimate collection of these advances is doubtful based upon PSN's
historical and forecasted operating results. Therefore, the Company fully
reserved the $500,000 receivable and charged $500,000 to other expense in 1997.
 
    The Company has a management services contract (the PSN Agreement) with PSN
to provide consulting, sales, and administrative support to PSN for a five-year
term beginning January 31, 1995.

8. MANAGEMENT SERVICES (CONTINUED)
During the years ended January 31, 1996, 1997 and 1998, the Company recorded
management service fees related to the PSN Agreement of $1,285,000, $1,344,000
and $1,378,000, respectively. Receivables from PSN for management services were
$342,000, $257,000 and $797,000 at January 31, 1996, 1997 and 1998,
respectively. Subsequent to January 31, 1998, the Company received payments from
PSN for management services in the amount of $362,000.
 
    The Company serves as Managing Director of INFITEQ, LLC (INFITEQ), a
single-source provider of specialized outsourcing services to the banking
industry for transaction processing, information management, electronic commerce
and image technology. The Company has a Management Services Agreement (the
INFITEQ Agreement) with INFITEQ to provide INFITEQ consulting, sales and
administrative support for a ten-year term beginning January 15, 1998. No
management service fees were recognized by the Company under this agreement
during the year ended January 31, 1998. The Company intends to recognize
management service fees under the INFITEQ Agreement on a cash basis in the near
term as INFITEQ has no operating history and is expected to generate operating
losses in its start-up phase.
 
    The Company has not provided guarantees of debt or other obligations, has
not agreed to fund any losses, or is not otherwise contingently liable with
respect to ECCHO, PSN or INFITEQ.
 
9. LEASE COMMITMENTS
 
    The Company leases office facilities and certain equipment under operating
leases for various periods. Leases that expire are generally expected to be
renewed or replaced by other leases. Rental expense under these leases for 1996,
1997 and 1998 was approximately $421,000, $527,000 and $580,000, respectively.
Future minimum base rents under terms of noncancelable operating leases (in
thousands) are as follows at January 31, 1998:

11. SUBSEQUENT EVENT
 
    Subsequent to January 31, 1998, the Company's Board of Directors authorized
management of the Company to file a Registration Statement with the Securities
and Exchange Commission to sell up to 3,650,000 shares of the Company's Common
Stock through an initial public offering (the Offering). The Company intends to
use the proceeds from the Offering for working capital and other general
corporate purposes. The Company may also use a portion of the proceeds for
possible strategic alliances and acquisitions of businesses, products and
technologies that are complementary to those of the Company. Pending such uses,
the Company plans to invest the net proceeds in short-term, interest-bearing,
investment grade securities. If the Offering is consummated, the Shareholder
Agreement with SAIC will terminate (Note 6).
 
    Subsequent to January 31, 1998, the Company's Board of Directors authorized
the merger of C-A Texas. The merger will be effected through the conversion of
each outstanding share of Class A voting Common Stock and Class B non-voting
Common Stock of C-A Texas into 7.7 shares of Common Stock of the Company.
Additionally, all options and rights to acquire shares of Class A and Class B
Common Stock of C-A Texas will be converted into rights to acquire shares of the
newly formed Delaware subsidiary on a basis consistent with the Common Stock
conversion ratio (Note 1).

*   To be supplied by amendment
 
ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    Section 145 of the Delaware General Corporation Law (the "DGCL") provides,
in effect, that any person made a party to any action by reason of the fact that
he is or was a director, officer, employee or agent of the Company may and, in
certain cases, must be indemnified by the Company against, in the case of a
non-derivative action, judgments, fines, amounts paid in settlement and
reasonable expenses (including attorney's fees) incurred by him as a result of
such action, and in the case of a derivative action, against expenses (including
attorney's fees), if in either type of action he acted in good faith and in a
manner he reasonably believed to be in or not opposed to the best interests of
the Company. This indemnification does not apply, in a derivative action, to
matters as to which it is adjudged that the director, officer, employee or agent
is liable to the Company, unless upon court order it is determined that, despite
such adjudication of liability, but in view of all the circumstances of the
case, he is fairly and reasonably entitled to indemnity for expenses, and, in a
non-derivative action, to any criminal proceeding in which such person had
reasonable cause to believe his conduct was unlawful.
 
    Article Eight of the Company's Certificate of Incorporation provides that no
director of the Company shall be liable to the Company or its stockholders for
monetary damages for breach of fiduciary duty as a director to the fullest
extent permitted by the DGCL.
 
    Article Eight of the Company's Certificate of Incorporation also provides
that the Company may indemnify to the fullest extent permitted by Delaware law
any and all of its directors and officers, or former directors and officers, or
any person who may have served at the Company's request as a director or officer
of another corporation, partnership, joint venture, trust or other enterprise.
In addition, Section 7.07 of the Company's Bylaws provides for similar
indemnification of officers and directors within the limits of Delaware law.
 
    Reference is made to the Underwriting Agreement which will be filed as part
of Exhibit 1.1 hereto, pursuant to which the underwriters have agreed to
indemnify officers and directors of the Company against certain liabilities
under the Securities Act.
 
    The Company will enter into Indemnification Agreements with each director of
the Company, a form of which will be filed as an Exhibit to this Registration
Statement. Pursuant to such agreements, the
 
                                      II-1
<PAGE>
Company will, to the extent permitted by applicable law, indemnify such
directors against all expenses, judgments, fines and penalties incurred in
connection with the defense or settlement of any actions brought against them by
reason of the fact that they were directors of the Company or assumed certain
responsibilities at the direction of the Company. The Company will also purchase
directors and officers liability insurance in order to limit its exposure to
liability for indemnification of directors and officers.
 
ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES.
 
    The following information relates to all securities issued or sold by the
Company within the past three years and not registered under the Securities Act.

will be exempt from registration under the Securities Act pursuant to Section
3(a)(9) thereof.
 
    On January 31, 1997 a wholly-owned subsidiary of the Company merged with and
into ASI, with the result that ASI became a wholly-owned subsidiary of the
Company (the "ASI Merger"). Pursuant to the ASI Merger, the Company issued

Securities Act, no public offering being involved.
 
    On January 10, 1997 the Company issued 269,500 shares of Common Stock to the
Crow Family Partnership, L.P. for $834,050. Such sale was completed without

public offering being involved.

ITEM 17.  UNDERTAKINGS.
 
    The undersigned Company hereby undertakes to provide the representatives of
the Underwriters at the closing specified in the Underwriting Agreement
certificates in such denominations and registered in such names as required by
the Underwriters to permit prompt delivery to each purchaser.
 
    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Company, the Company has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the Company
of expenses incurred or paid by a director, officer or controlling person of the
Company in the successful defense of any action, suit or proceeding) is asserted
by any director, officer or controlling person in connection with the securities
being registered, the Company will, unless in the opinion of 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 Act and will be governed by the final
adjudication of such issue.
 
    The Company hereby undertakes that:
 
    (1) For purposes of determining any liability under the Act, the information
       omitted from the form of Prospectus filed as part of this Registration
       Statement in reliance upon Rule 430A and contained in a form of
       prospectus filed by the Company pursuant to Rule 424(b)(1) or (4) or
       497(h) under the Act shall be deemed to be part of this Registration
       Statement as of the time it was declared effective.
 
    (2) For the purpose of determining any liability under the Act, each
       post-effective amendment that contains a form of Prospectus 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.

                             EMPLOYMENT AGREEMENT

     This EMPLOYMENT AGREEMENT (this "AGREEMENT") shall become effective as of
the Effective Date indicated below between The Carreker Group, Inc., a Texas
corporation (the "COMPANY"), and J.D. Carreker ("MR. CARREKER").

                                    RECITAL

     Mr. Carreker is the Chief Executive Officer and Chairman of the board of
directors of the Company.  In consideration for the Company's entering into and
performing under this Agreement, Mr. Carreker has also agreed to enter into
this Agreement.

     NOW, THEREFORE, in consideration of the foregoing and the mutual
agreements of the parties contained herein, the Company and Mr. Carreker hereby
agree as follows:

     1.   EMPLOYMENT.   The Company will employ Mr. Carreker and Mr. Carreker
accepts employment with the Company for a period of two years from the
Effective Date; provided, however, that by irrevocable written notice given to
the Company not less than six months prior to the expiration of such two year
period, Mr. Carreker may extend the period by an additional year (such two or
three year period, as applicable, being the "INITIAL PERIOD").  Mr. Carreker's
employment may continue after the Initial Period but will then be terminable by
either party at will, with or without cause (provided that any termination by
the Company shall occur only pursuant to a determination of its board of
directors (and not a committee thereof)), which determination may be made in
its sole discretion.  The obligations of the Company and Mr. Carreker set forth
in the "Intellectual Property Rights Agreement" and the "Confidentiality
Agreement" (each as defined in Section 7) (referring to intellectual property
and confidentiality, respectively) and in Section 8 (referring to termination)
will survive termination of Mr. Carreker's employment, regardless of cause.

          Mr. Carreker's primary location of employment shall be in Dallas,
Texas or its environs, and he shall undertake such business travel as is
reasonably required in the discharge of his duties set forth below.

     2.   DUTIES.  Mr. Carreker will be employed as a full-time employee of the
Company and initially will serve as its Chief Executive Officer and as a
director.  Mr. Carreker agrees that, to the best of his ability and experience,
he will at all times conscientiously perform all of the duties and obligations
assigned to him under this Agreement.

     3.   FULL-TIME EMPLOYMENT.  Mr. Carreker's employment will be on a full-
time basis, in accordance with standard employee policies for the Company.  Mr.
Carreker will not engage in any other business or render any commercial or
professional services, directly or indirectly, to any other person or
organization, whether for compensation or otherwise, provided that Mr. Carreker
may (i) provide incidental assistance to family members on matters of family
business; and (ii) sit on the board of directors of corporations and other
organizations (including, without limitation, charitable and other nonprofit
organizations) that do not compete with the Company; provided in each case that
such activities do not conflict with or interfere with Mr. Carreker's 

<PAGE>

normal full-time and first priority obligations to the Company.  Mr. Carreker 
may make personal investments in nonpublicly traded corporations, 
partnerships or other entities that, to the knowledge of the Company, are not 
at the time of such investment engaged in any business activities competitive 
with the Company. Notwithstanding anything to the contrary contained in this 
Agreement, Mr. Carreker may make personal investments in publicly traded 
corporations regardless of the business they are engaged in, provided that 
Mr. Carreker does not at any time own in excess of 1% of the issued and 
outstanding stock of any such corporation.

     4.   SALARY; POTENTIAL BONUS.  Mr. Carreker's salary for the first year of
the Initial Period will be not less than $450,000.  If the Company does not
consummate an initial public offering of its equity securities during such
first year and if the Company's financial performance meets or exceeds the
standards for financial performance established in respect of such first year
by the Company's board of directors (i.e., the Company's "board plan"), then
Mr. Carreker's salary for the second year of the Initial Period will be not
less than $500,000.  If Mr. Carreker validly exercises his option to extend the
term hereof such that the Initial Period is three years, if the Company does
not consummate an initial public offering of its equity securities during the
second year of the Initial Period and if the Company's financial performance
meets or exceeds the standards for financial performance established in respect
of such second year by the Company's board of directors, then Mr. Carreker's
salary for the third year of the Initial Period will be not less than $550,000.
All salary is payable on the Company's regular payroll dates, less required
withholdings.

     Mr. Carreker acknowledges that the Company's board of directors has
complete and sole discretion to establish and revise the Company's "board
plan."

     The board of directors of the Company has the sole discretion whether or
not to establish a bonus pool.  If and to the extent the board of directors of
the Company establishes a bonus pool for 1997 or any subsequent year, then Mr.
Carreker will be entitled to participate in the same.

     5.   BENEFITS.  Mr. Carreker will also be entitled to insurance, vacation
and other benefits commensurate with his position in accordance with the
Company's standard employee policies in effect from time to time.  Mr. Carreker
acknowledges receipt of a summary of the Company's standard employee benefits
policies in effect as of the date hereof.

     6.   REIMBURSEMENT OF BUSINESS EXPENSES.  The Company will, in accordance
with the Company's policies in effect from time to time, reimburse Mr. Carreker
for all out-of-pocket reasonable business expenses incurred by Mr. Carreker in
connection with the performance of his duties under this Agreement upon
submission of the required documentation required pursuant to the Company's
standard policies and record-keeping procedures.

     7.   INTELLECTUAL PROPERTY.  Simultaneously with the execution of this
Agreement, Mr. Carreker is executing and delivering and hereby adopts and
agrees to be bound by the Intellectual Property Rights Agreement, a copy of
which is attached to this Agreement as ATTACHMENT A, and by the Confidentiality
Agreement, a copy of which is attached to this Agreement as ATTACHMENT B.

     8.   TERMINATION.

          (a)  THE COMPANY.  Notwithstanding Section 1, the Company, acting by a
determination of its board of directors (and not a committee thereof), may
terminate Mr. Carreker's employment at any time during the Initial Period
(whether two or three years) with or without cause upon written notice to Mr.
Carreker.

          (b)  BY MR. CARREKER.  During the first two years of the Initial 
Period (i.e., determined without regard to an extension of the Initial Period 
to three years), Mr. Carreker may terminate Mr. Carreker's employment upon 
written notice to the Company only if the Company is in material breach of 
this Agreement, provided that such termination will become effective only 
upon the expiration of 30 days following such notice and then only if the 
breach remains uncured.  Such termination shall be deemed a termination by 
the Company of Mr. Carreker's employment under Section 8(a) for which Mr. 
Carreker shall have the remedy set forth in Section 8(c).

          (c)  REMEDY.  Upon termination of Mr. Carreker's employment pursuant 
to Section 8(a) without cause or Section 8(b) only (at which time he shall cease
to be an employee of the Company for all purposes, including for all benefit
plan, insurance and other purposes), the Company will pay to Mr. Carreker, on
the Company's regular payroll dates and less required withholdings (if any),
salary at the rate paid to Mr. Carreker immediately prior to such termination,
for the remaining balance (if any) of the first two years of the Initial Period
(i.e., determined without regard to an extension of the Initial Period to three
years) (the "TERMINATION PAYMENTS").  The Company's obligation to make the
Termination Payments pursuant to this Section 8(c) is in lieu of any damages or
any other payment or benefits, including without limitation stock benefits,
that the Company might otherwise be obligated to pay Mr. Carreker as a result
of Mr. Carreker's termination of employment; PROVIDED, HOWEVER, that if at any
time the Company terminates Mr. Carreker's employment without cause under
circumstances in which Mr. Carreker is not entitled to Termination Payments, or
is entitled to Termination Payments that in the aggregate are less than a lump-
sum severance payment consistent with the Company's standard severance payment
policy, if any, as may be in effect at the time of termination, then Mr.
Carreker shall be entitled to such lump-sum severance payment.  (For purposes
of reference and example only, the Company's standard severance payment policy
as of the date of this Agreement provides for the payment of one week's salary
at the time of termination for each year of service as an employee.)  The
Company and Mr. Carreker agree that, in view of the nature of the issues likely
to arise in the event of such a termination, it would be impracticable or
extremely difficult to fix the actual damages resulting from such termination
and proving actual damages, causation and foreseeability in the case of such
termination would be costly, inconvenient and difficult.  In requiring the
Company to make the Termination Payments as set forth herein, it is the intent
of the parties to provide, as of the date of this Agreement, for a liquidated
amount of damages to be paid by the Company to Mr. Carreker.  Such liquidated
amount shall be deemed full and adequate damages for such termination and is
not intended by either party to be a penalty.


EMPLOYMENT AGREEMENT - Page 3

<PAGE>

          (d)  UPON DEATH.  If Mr. Carreker dies during the term of this 
Agreement, then the Company will pay his estate an amount equal to all salary 
accrued, bonuses (if any) accrued and payable and benefits accrued as of the 
date of his death.

          (e)  SURVIVAL.  Mr. Carreker's and the Company's obligations under
Sections 7, 8 and 9(i) of this Agreement will survive the termination of
Carreker's employment of Mr. Carreker.

          (f)  CAUSE.  As used in this Agreement the term "with cause" shall 
mean and be limited to: (i) a material breach of this Agreement by Mr. 
Carreker that is not corrected within thirty (30) days after written notice 
of same from the board of directors of the Company to Mr. Carreker; (ii) 
gross and willful neglect by Mr. Carreker of his duties and responsibilities 
hereunder; (iii) fraud, criminal misconduct, breach of fiduciary duty, 
dishonesty, or gross and willful misconduct by Mr. Carreker in connection 
with the performance of his duties and responsibilities hereunder; (iv) Mr. 
Carreker being under the influence of alcohol or drugs during business hours, 
or being habitually drunk or addicted to drugs; (v) the commission by Mr. 
Carreker of any crime of moral turpitude; (vi) material breach by Mr. 
Carreker of his obligations under any assignment of copyright and other 
intellectual property rights, noncompetition agreement, trade secret 
agreement or confidentiality agreement, which breach is not cured within 
thirty (30) days after written notice of same from the board of directors of 
the Company to Mr. Carreker; or (vii) habitual breach by Mr. Carreker of any 
of the material provisions of this Agreement or such other assignment or 
agreements (regardless of any prior cure thereof).

     9.   MISCELLANEOUS.

          (a)  NOTICES.  Any and all notice permitted or required to be given

the Company under this Agreement may be assigned to a corporation which
succeeds the Company as the result of a merger or other corporate
reorganization and which continues the business of the Company, or a subsidiary
of the Company, provided that the Company guarantees the performance by such
assignee of the Company's obligations hereunder.

          (d)  GOVERNING LAW.  The laws of the State of Texas (without regard 
to its choice of law principles that might apply the law of another 
jurisdiction) will govern the validity of this Agreement, the construction of 
its terms, and the interpretation and enforcement of the rights and duties of 
the parties.

          (e)  NO WAIVER.  The failure of any party to enforce any of the 
provisions hereof will not be construed to be a waiver of the right of such 
party thereafter to enforce such provisions.  The waiver by any party of the 
right to enforce any of the provisions hereof on any occasion will not be 
construed to be a waiver of the right of such party to enforce such 
provisions on any other occasion.

          (f)  SEVERABILITY.  Mr. Carreker and the Company recognize that the 
limitations contained in this Agreement are reasonably and properly required 
for the adequate protection of the interests of the Company.  If for any 
reason a court of competent jurisdiction or an arbitrator in a binding 
arbitration proceeding finds any provision of this Agreement, or the 
application thereof, to be unenforceable, then the remaining provisions of 
this Agreement will be interpreted so as best to reasonably effect the intent 
of the parties.  The parties further agree that the court or arbitrator shall 
replace any such invalid or unenforceable provisions with valid and 
enforceable provisions designed to achieve, to the extent possible, the 
business purposes and intent of such unenforceable provisions.

          (g)  COUNTERPARTS.  This Agreement may be executed in counterparts, 
each of which will be an original as regards any party whose signature 
appears thereon and all of which 


EMPLOYMENT AGREEMENT - Page 5

<PAGE>

together will constitute one and the same instrument. This Agreement will 
become binding when one or more counterparts hereof, individually or taken 
together, bear the signatures of both parties reflected hereon as signatories.

          (h)  EFFECT OF AGREEMENT.  This Agreement will be void and have no 
effect if the Effective Date does not occur on or before February 1, 1997.

          (i)  DISPUTE RESOLUTION.

               (i)    ARBITRATION OF DISPUTES.  Any dispute under this 
Agreement shall be resolved by arbitration in Dallas, Texas and, except as 
herein specifically stated, in accordance with the commercial arbitration 
rules of the American Arbitration Association ("AAA RULES") then in effect.  
However, in all events, these arbitration provisions shall govern over any 
conflicting rules that may now or hereafter be contained in the AAA Rules.  
Any judgment upon the award rendered by the arbitrator may be entered in any 
court having jurisdiction over the subject matter thereof.  The arbitrator 
shall have the authority to grant any equitable and legal remedies that would 
be available in any judicial proceeding instituted to resolve such dispute.

               (ii)   COMPENSATION OF ARBITRATOR.  Any such arbitration will 
be conducted before a single arbitrator who will be compensated for his or 
her services at a rate to be determined by the parties or by the American 
Arbitration Association, but based upon reasonable hourly or daily consulting 
rates for the arbitrator if the parties are not able to agree upon his or her 
rate of compensation.

               (iii)  SELECTION OF ARBITRATOR.  The American Arbitration 
Association will have the authority to select an arbitrator from a list of 
arbitrators who are lawyers familiar with Texas contract law; PROVIDED, 
HOWEVER, that such lawyers cannot work for a firm then performing services 
for either party, that each party will have the opportunity to make such 
reasonable objection to any of the arbitrators listed as such party may wish 
and that the American Arbitration Association will select the arbitrator from 
the list of arbitrators as to whom neither party makes any such objection.  
If the foregoing procedure is not followed, then each party will choose one 
person from the list of arbitrators provided by the American Arbitration 
Association (provided that such person does not have a conflict of interest), 
and the two persons so selected will select from the list provided by the 
American Arbitration Association the person who will act as the arbitrator.

               (iv)   PAYMENT OF COSTS.  The Company and Mr. Carreker will 
each pay 50% of the initial compensation to be paid to the arbitrator in any 
such arbitration and 50% of the costs of transcripts and other normal and 
regular expenses of the arbitration proceedings; PROVIDED, HOWEVER, that the 
prevailing party in any arbitration will be entitled to an award of 
attorneys' fees and costs, and all costs of arbitration, including those 
provided for above, will be paid by the non-prevailing party, and the 
arbitrator will be authorized to make such determinations.

               (v)    BURDEN OF PROOF.  For any dispute submitted to 
arbitration, the burden of proof will be as it would be if the claim were 
litigated in a Texas judicial proceeding.


EMPLOYMENT AGREEMENT - Page 6

<PAGE>

               (vi)   AWARD.  Upon the conclusion of any arbitration 
proceedings hereunder, the arbitrator will render findings of fact and 
conclusions of law and a written opinion setting forth the basis and reasons 
for any decision reached and will deliver such documents to each party to 
this Agreement along with a signed copy of the award.

               (vii)  TERMS OF ARBITRATION.  The arbitrator chosen in 
accordance with these provisions will not have the power to alter, amend or 
otherwise affect the terms of these arbitration provisions or the provisions 
of this Agreement.

               (viii) NATURE OF REMEDY.  Except as specifically otherwise 
provided below, arbitration will be the sole and exclusive remedy of the 
parties for any dispute arising out of this Agreement.

               (ix)   EQUITABLE REMEDY.  Notwithstanding the provisions of 
this Section 9(i) and the arbitration provided for herein, actions initiated 
or maintained by the parties for injunctive or similar equitable relief are 
not subject to arbitration, and may be brought by the parties in any court 
that has jurisdiction, and, should the party bringing any such action 
prevail, all costs and expenses (including legal fees) shall be borne by the 
party against whom such action was brought.

                                                                   EXHIBIT 10.2

                             EMPLOYMENT AGREEMENT

     This EMPLOYMENT AGREEMENT (this "AGREEMENT") shall become effective as of
the Effective Date indicated below between The Carreker Group, Inc., a Texas
corporation ("CARREKER"), and Ronald R. Antinori ("MR. ANTINORI").

                                   RECITALS

     A.  This Agreement is entered into connection with and is ancillary to an
Agreement and Plan of Merger (the "AGREEMENT") dated as of January 29, 1997
between Carreker and Antinori Software Inc., a Georgia corporation, pursuant to
which a wholly-owned subsidiary of Carreker is to merge with and into Antinori
Software, Inc. (the "MERGER"), such that Antinori Software, Inc. will become a
wholly-owned subsidiary of Carreker.  The date on which the Merger becomes
effective will be the effective date of this Agreement (the "EFFECTIVE DATE").
As provided in Section 9(h) below, this Agreement will be void and have no
effect if the Merger does not become effective, i.e., the Effective Date does
not occur, by February 1, 1997.

     B.  Mr. Antinori is the principal shareholder and the Chairman of the
board of directors of Antinori Software, Inc. and has been and remains actively
involved in the development and marketing of Antinori Software, Inc.'s
products.  Carreker intends to continue the business of Antinori Software, Inc.
after the Merger and integrate such business into Carreker's ongoing business.
To preserve and protect the assets of Antinori Software, Inc., including
Antinori Software, Inc.'s goodwill, customers and trade secrets of which Mr.
Antinori has and will have knowledge and to preserve and protect Carreker's
goodwill and business interests going forward, and in consideration for
Carreker's entering into and performing under the Agreement, Mr. Antinori has
agreed to enter into this Agreement.

     C.  In addition, as contemplated by Section 7 below, Mr. Antinori is
concurrently herewith entering into an Intellectual Property Rights Agreement
and a Confidentiality Agreement in favor of Carreker for the purpose of
protecting Carreker's proprietary rights.

     NOW, THEREFORE, in consideration of the foregoing and the mutual
agreements of the parties contained herein, Carreker and Mr. Antinori hereby
agree as follows:

     1.  EMPLOYMENT.  Carreker will employ Mr. Antinori and Mr. Antinori
accepts employment with Carreker for a period of two years from the Effective
Date; provided, however, that by irrevocable written notice given to the
Company not less than six months prior to the expiration of such two year
period, Mr. Antinori may extend the period by an additional year (such two or
three year period, as applicable, being the "INITIAL PERIOD").  Mr. Antinori's
employment may continue after the Initial Period but will then be terminable by
either party at will, with or without cause (provided that any termination by
Carreker shall occur only pursuant to a determination of its board of directors
(and not a committee thereof)), which determination may be made in its sole
discretion.  The obligations of Carreker and Mr. Antinori set forth in the
"Intellectual Property Rights Agreement" and the "Confidentiality Agreement"
(each as defined in Section 7) (referring to intellectual property and
confidentiality, respectively) and in Section 

<PAGE>

8 (referring to termination) will survive termination of Mr. Antinori's 
employment, regardless of cause.

     Mr. Antinori's primary location of employment shall be in Atlanta, Georgia
or its environs, and he shall undertake such business travel as is reasonably
required in the discharge of his duties set forth below.

     2.   DUTIES.  Mr. Antinori will be employed as a full-time employee of
Carreker and will serve as Vice Chairman, Product and Business Development,
reporting directly to the Chairman of the Board.  Mr. Antinori agrees that, to
the best of his ability and experience, he will at all times conscientiously
perform all of the duties and obligations assigned to him under this Agreement.

     3.   FULL-TIME EMPLOYMENT.  Mr. Antinori's employment will be on a full-
time basis, in accordance with standard employee policies for Carreker.  Mr.
Antinori will not engage in any other business or render any commercial or
professional services, directly or indirectly, to any other person or
organization, whether for compensation or otherwise, provided that Mr. Antinori
may (i) provide incidental assistance to family members on matters of family
business; and (ii) sit on the boards of corporations and other organizations
(including, without limitation, charitable and other nonprofit organizations)
that do not compete with Carreker; provided in each case that such activities
do not conflict with or interfere with Mr. Antinori's normal full-time and
first priority obligations to Carreker.  Mr. Antinori may make personal
investments in nonpublicly traded corporations, partnerships or other entities
that, to the knowledge of Carreker, are not at the time of such investment
engaged in any business activities competitive with Carreker.  Notwithstanding
anything to the contrary contained in this Agreement, Mr. Antinori may make
personal investments in publicly traded corporations regardless of the business
they are engaged in, provided that Mr. Antinori does not at any time own in
excess of 1% of the issued and outstanding stock of any such corporation.

     4.   SALARY; POTENTIAL BONUS.  Mr. Antinori's salary for the first year of
the Initial Period will be not less than $350,000.  If the Company does not
consummate an initial public offering of its equity securities during such
first year and if the Company's financial performance meets or exceeds the
standards for financial performance established in respect of such first year
by the Company's board of directors (i.e., the Company's "board plan"), then
Mr. Antinori's salary for the second year of the Initial Period will be not
less than $400,000.  If Mr. Antinori validly exercises his option to extend the
term hereof such that the Initial Period is three years, if the Company does
not consummate an initial public offering of its equity securities during the
second year of the Initial Period and if the Company's financial performance
meets or exceeds the standards for financial performance established in respect
of such second year by the Company's board of directors, then Mr. Antinori's
salary for the third year of the Initial Period will be not less than $450,000.
All salary is payable on Carreker's regular payroll dates, less required
withholdings.

     Mr. Antinori acknowledges that the Company's board of directors has
complete and sole discretion to establish and revise the Company's "board
plan."


EMPLOYMENT AGREEMENT - Page 2

<PAGE>

     The board of directors of Carreker has the sole discretion whether or not
to establish a bonus pool.  If and to the extent the board of directors of
Carreker establishes a bonus pool for 1997 or any subsequent year, then Mr.
Antinori will be entitled to participate in the same at a level consistent with
the participation of that of the Chairman of Carreker.

     In further consideration of his execution and delivery of this Agreement,
Mr. Antinori shall receive a cash bonus of $175,000, less required
withholdings, on the Effective Date.

     5.   BENEFITS.  Mr. Antinori will also be entitled to insurance, vacation
and other benefits commensurate with his position (and consistent with the
level of such benefits as are afforded the Chairman of Carreker) in accordance
with Carreker's standard employee policies in effect from time to time.  Mr.
Antinori acknowledges receipt of a summary of Carreker's standard employee
benefits policies in effect as of the date hereof.

     6.   REIMBURSEMENT OF BUSINESS EXPENSES.  Carreker will, in accordance
with Carreker's policies in effect from time to time, reimburse Mr. Antinori
for all out-of-pocket reasonable business expenses incurred by Mr. Antinori in
connection with the performance of his duties under this Agreement upon
submission of the required documentation required pursuant to Carreker's
standard policies and record-keeping procedures (and consistent with the
application of such policies to the Chairman of Carreker).

     7.   INTELLECTUAL PROPERTY AND CONFIDENTIALITY.  Simultaneously with the
execution of this Agreement, Mr. Antinori is executing and delivering and
hereby adopts and agrees to be bound by the Intellectual Property Rights
Agreement and the Confidentiality Agreement, a copy of each of which is
attached to this Agreement as ATTACHMENT A and ATTACHMENT B, respectively.

     8.   TERMINATION.

          (a)  CARREKER.  Notwithstanding Section 1, Carreker, acting by a
determination of its board of directors (and not a committee thereof), may
terminate Mr. Antinori's employment at any time during the Initial Period
(whether two or three years) with or without cause upon written notice to Mr.
Antinori.

          (b)  BY MR. ANTINORI.  During the first two years of the Initial 
Period (i.e., determined without regard to an extension of the Initial Period 
to three years), Mr. Antinori may terminate Mr. Antinori's employment upon 
written notice to Carreker only if Carreker is in material breach of this 
Agreement, provided that such termination will become effective only upon the 
expiration of 30 days following such notice and then only if the breach 
remains uncured. Such termination shall be deemed a termination by Carreker 
of Mr. Antinori's employment under Section 8(a) for which Mr. Antinori shall 
have the remedy set forth in Section 8(c).

          (c)  REMEDY.  Upon termination of Mr. Antinori's employment pursuant 
to Section 8(a) without cause or Section 8(b) only (at which time he shall 
cease to be an employee of Carreker for all purposes, including for all 
benefit plan, insurance and other purposes), Carreker will pay to Mr. 
Antinori, on Carreker's regular payroll dates and less required 


EMPLOYMENT AGREEMENT - Page 3

<PAGE>

withholdings, salary at the rate paid to Mr. Antinori immediately prior to 
such termination, for the remaining balance (if any) of the first two years 
of the Initial Period (i.e., determined without regard to an extension of the 
Initial Period to three years) (the "TERMINATION PAYMENTS").  Carreker's 
obligation to make the Termination Payments pursuant to this Section 8(c) is 
in lieu of any damages or any other payment or benefits, including without 
limitation stock benefits, that Carreker might otherwise be obligated to pay 
Mr. Antinori as a result of Mr. Antinori's termination of employment; 
PROVIDED, HOWEVER, that if at any time Carreker terminates Mr. Antinori's 
employment without cause, under circumstances in which Mr. Antinori is not 
entitled to Termination Payments, or is entitled to Termination Payments that 
in the aggregate are less than a lump-sum severance payment consistent with 
Carreker's standard severance payment policy, if any, as may be in effect at 
the time of termination, determined with applicable credit for Mr. Antinori's 
time of service with Antinori Software, Inc., then Mr. Antinori shall be 
entitled to such lump-sum severance payment.  (For purposes of reference and 
example only, Carreker's standard severance payment policy as of the date of 
this Agreement provides for the payment of one week's salary at the time of 
termination for each year of service as an employee.) Carreker and Mr. 
Antinori agree that, in view of the nature of the issues likely to arise in 
the event of such a termination, it would be impracticable or extremely 
difficult to fix the actual damages resulting from such termination and 
proving actual damages, causation and foreseeability in the case of such 
termination would be costly, inconvenient and difficult.  In requiring 
Carreker to make the Termination Payments as set forth herein, it is the 
intent of the parties to provide, as of the date of this Agreement, for a 
liquidated amount of damages to be paid by Carreker to Mr. Antinori.  Such 
liquidated amount shall be deemed full and adequate damages for such 
termination and is not intended by either party to be a penalty.

          (d)  UPON DEATH.  If Mr. Antinori dies during the term of this 
Agreement, then Carreker will pay his estate an amount equal to all salary 
accrued, bonuses (if any) accrued and payable and benefits accrued as of the 
date of his death.

          (e)  SURVIVAL.  Mr. Antinori's and Carreker's obligations under 
Sections 7, 8 and 9(i) of this Agreement will survive the termination of 
Carreker's employment of Mr. Antinori.

          (f)  CAUSE.  As used in this Agreement the term "with cause" shall 
mean and be limited to:  (i) a material breach of this Agreement by Mr. 
Antinori that is not corrected within thirty (30) days after written notice 
of same from the board of directors of Carreker to Mr. Antinori; (ii) gross 
and willful neglect by Mr. Antinori of his duties and responsibilities 
hereunder; (iii) fraud, criminal misconduct, breach of fiduciary duty, 
dishonesty, or gross and willful misconduct by Mr. Antinori in connection 
with the performance of his duties and responsibilities hereunder; (iv) Mr. 
Antinori being under the influence of alcohol or drugs during business hours, 
or being habitually drunk or addicted to drugs; (v) the commission by Mr. 
Antinori of any crime of moral turpitude; (vi) material breach by Mr. 
Antinori of his obligations under any assignment of copyright and other 
intellectual property rights, noncompetition agreement, trade secret 
agreement or confidentiality agreement, which breach is not cured within 
thirty (30) days after written notice of same from the board of directors of 
Carreker to Mr. Antinori; or (vii) habitual breach by Mr. Antinori of any of 
the material provisions of this Agreement or such other assignment or 
agreements (regardless of any prior cure thereof).

          (b)  AMENDMENTS.  This Agreement, including the Attachments hereto,

EMPLOYMENT AGREEMENT - Page 5

<PAGE>

employment and employment benefits.  This Agreement may not be changed or 
modified in whole or in part except by a writing signed by the party against 
whom enforcement of the change or modifications is sought.

          (c)  SUCCESSORS AND ASSIGNS.  This Agreement will not be assignable by
either Mr. Antinori or Carreker, except that the rights and obligations of
Carreker under this Agreement may be assigned to a corporation which succeeds
Carreker as the result of a merger or other corporate reorganization and which
continues the business of Carreker, or a subsidiary of Carreker, provided that
Carreker guarantees the performance by such assignee of Carreker's obligations
hereunder.

          (d)  GOVERNING LAW.  The laws of the State of Texas (without regard 
to its choice of law principles that might apply the law of another 
jurisdiction) will govern the validity of this Agreement, the construction of 
its terms, and the interpretation and enforcement of the rights and duties of 
the parties.

          (e)  NO WAIVER.  The failure of any party to enforce any of the 
provisions hereof will not be construed to be a waiver of the right of such 
party thereafter to enforce such provisions.  The waiver by any party of the 
right to enforce any of the provisions hereof on any occasion will not be 
construed to be a waiver of the right of such party to enforce such 
provisions on any other occasion.

          (f)  SEVERABILITY.  Mr. Antinori and Carreker recognize that the
limitations contained in this Agreement are reasonably and properly required
for the adequate protection of the interests of Carreker.  If for any reason a
court of competent jurisdiction or an arbitrator in a binding arbitration
proceeding finds any provision of this Agreement, or the application thereof,
to be unenforceable, then the remaining provisions of this Agreement will be
interpreted so as best to reasonably effect the intent of the parties.  The
parties further agree that the court or arbitrator shall replace any such
invalid or unenforceable provisions with valid and enforceable provisions
designed to achieve, to the extent possible, the business purposes and intent
of such unenforceable provisions.

          (g)  COUNTERPARTS.  This Agreement may be executed in counterparts, 
each of which will be an original as regards any party whose signature 
appears thereon and all of which together will constitute one and the same 
instrument. This Agreement will become binding when one or more counterparts 
hereof, individually or taken together, bear the signatures of both parties 
reflected hereon as signatories.

          (h)  EFFECT OF AGREEMENT.  This Agreement will be void and have no 
effect if the Effective Date does not occur on or before February 1, 1997.

          (i)  DISPUTE RESOLUTION.

               (i)  ARBITRATION OF DISPUTES.  Any dispute under this 
Agreement shall be resolved by arbitration in Dallas, Texas and, except as 
herein specifically stated, in accordance with the commercial arbitration 
rules of the American Arbitration Association ("AAA RULES") 


EMPLOYMENT AGREEMENT - Page 6

<PAGE>

then in effect.  However, in all events, these arbitration provisions shall 
govern over any conflicting rules that may now or hereafter be contained in 
the AAA Rules.  Any judgment upon the award rendered by the arbitrator may be 
entered in any court having jurisdiction over the subject matter thereof.  
The arbitrator shall have the authority to grant any equitable and legal 
remedies that would be available in any judicial proceeding instituted to 
resolve such dispute.

               (ii)   COMPENSATION OF ARBITRATOR.  Any such arbitration will 
be conducted before a single arbitrator who will be compensated for his or 
her services at a rate to be determined by the parties or by the American 
Arbitration Association, but based upon reasonable hourly or daily consulting 
rates for the arbitrator if the parties are not able to agree upon his or her 
rate of compensation.

               (iii)  SELECTION OF ARBITRATOR.  The American Arbitration 
Association will have the authority to select an arbitrator from a list of 
arbitrators who are lawyers familiar with Texas contract law; provided, 
however, that such lawyers cannot work for a firm then performing services 
for either party, that each party will have the opportunity to make such 
reasonable objection to any of the arbitrators listed as such party may wish 
and that the American Arbitration Association will select the arbitrator from 
the list of arbitrators as to whom neither party makes any such objection.  
If the foregoing procedure is not followed, then each party will choose one 
person from the list of arbitrators provided by the American Arbitration 
Association (provided that such person does not have a conflict of interest), 
and the two persons so selected will select from the list provided by the 
American Arbitration Association the person who will act as the arbitrator.

               (iv)   PAYMENT OF COSTS.  Carreker and Mr. Antinori will each 
pay 50% of the initial compensation to be paid to the arbitrator in any such 
arbitration and 50% of the costs of transcripts and other normal and regular 
expenses of the arbitration proceedings; provided, however, that the 
prevailing party in any arbitration will be entitled to an award of 
attorneys' fees and costs, and all costs of arbitration, including those 
provided for above, will be paid by the non-prevailing party, and the 
arbitrator will be authorized to make such determinations.

               (v)    BURDEN OF PROOF.  For any dispute submitted to 
arbitration, the burden of proof will be as it would be if the claim were 
litigated in a Texas judicial proceeding.

               (vi)   AWARD.  Upon the conclusion of any arbitration 
proceedings hereunder, the arbitrator will render findings of fact and 
conclusions of law and a written opinion setting forth the basis and reasons 
for any decision reached and will deliver such documents to each party to 
this Agreement along with a signed copy of the award.

               (vii)  TERMS OF ARBITRATION.  The arbitrator chosen in 
accordance with these provisions will not have the power to alter, amend or 
otherwise affect the terms of these arbitration provisions or the provisions 
of this Agreement.

               (viii) NATURE OF REMEDY.  Except as specifically otherwise 
provided in this Agreement, arbitration will be the sole and exclusive remedy 
of the parties for any dispute arising out of this Agreement.

               (ix)   EQUITABLE REMEDY.  Notwithstanding the provisions of 
this Section 9(i) and the arbitration provided for herein, actions initiated 
or maintained by the parties for injunctive or similar equitable relief are 
not subject to arbitration and may be brought by the parties in any court 
that has jurisdiction, and should the party bringing any such action prevail, 
all costs and expenses (including legal fees) shall be borne by the party 
against whom such action was brought.

          (j)  TAX AUDIT AGREEMENT.  If, following the Closing, Ronald R. 
Antinori receives notice of any audit or examination by any taxing authority 
of any tax return for Antinori for any period prior to, or prior to and 
including, the Closing, then Ronald R. Antinori shall promptly notify 
Carreker of such notice and Carreker at its own expense may participate in 
such audit or examination and shall be kept apprised by Ronald R. Antinori of 
the progress of such audit or examination.  Ronald R. Antinori agrees that he 
will not agree to any audit adjustment or revision that would adversely 
affect Carreker without Carreker's approval or agreement, which approval or 
agreement shall not be unreasonably withheld.

                             EMPLOYMENT AGREEMENT

     This EMPLOYMENT AGREEMENT (this "AGREEMENT") is entered into on this 12th
day of March 1998 between Carreker-Antinori, Inc., a Texas corporation (the
"COMPANY"), and Wyn P. Lewis ("MR. LEWIS").

                                   RECITALS

     This Agreement sets forth in definitive form the terms of Mr. Lewis's
employment by the Company.

     NOW, THEREFORE, in consideration of the foregoing and the mutual
agreements of the parties contained herein, the Company and Mr. Lewis hereby
agree as follows:

     1.   EMPLOYMENT.  The Company will employ Mr. Lewis and Mr. Lewis accepts
employment with the Company for a period of three years beginning on the date
of this Agreement (the "INITIAL PERIOD").  Mr. Lewis's employment may continue
after the Initial Period but will then be terminable by either party at will,
with or without cause.  The obligations of the Company and Mr. Lewis set forth
in that certain "Noncompetition, Property Rights and Trade Secrets Agreement"
and in that certain "Confidentiality Agreement" (each as defined in Section 8)
(referring to noncompetition, intellectual property rights and confidentiality,
respectively) and in Section 9 (referring to termination) will survive
termination of Mr. Lewis's employment, regardless of reason.

     2.   RESIDENCE AND BUSINESS TRAVEL.  Each of the parties agrees that the
primary location at which Mr. Lewis will be expected to render services
hereunder will be in Dallas, Texas or its environs, but that Mr. Lewis will,
from time to time, be expected to travel to other locations where the Company
transacts (or proposes to transact) business and undertake such other business
travel as is reasonably required in the discharge of his duties set forth below
and for the successful operation of the Company.

     3.   DUTIES.  As of the date of this Agreement, Mr. Lewis is employed as
Executive Vice President and Managing Director - Yield Management Group of the
Company, reporting to the President and Chief Operating Officer of the Company.
In such capacity, Mr. Lewis shall be responsible for the performance,
management, supervision and function of the Yield Management Group of the
Company.

     Mr. Lewis agrees that, to the best of his ability and experience, he will
at all times conscientiously (a) perform the foregoing duties and
responsibilities, or such other or additional duties and responsibilities,
and/or (b) hold such other or additional offices, as in either case may be
assigned to him from time to time by the Company's Chief Executive Officer, the
Company's President and Chief Operating Officer or the Company's Board of
Directors.

     In discharging his duties, Mr. Lewis shall have such authority as is
reasonably necessary to perform such duties.

<PAGE>

     4.   FULL-TIME EMPLOYMENT.  Mr. Lewis's employment will be on a full-time
basis, in accordance with policies of the Company applicable to executive
officers.  In addition to such restrictions as are set forth in the
Noncompetition, Property Rights and Trade Secrets Agreement referenced herein,
Mr. Lewis will not engage in any other business or render any commercial or
professional services, directly or indirectly, to any other person or
organization, whether for compensation or otherwise, provided that Mr. Lewis
may (a) provide incidental assistance to family members on matters of family
business or with respect to their personal investments; (b) engage in
charitable activities on behalf of civic, educational or other nonprofit
organizations; and (c) subject to the approval of the Company's Chief Executive
Officer (which approval may be given or withheld in his or her sole
discretion), sit on the board of directors of corporations and other business
organizations; provided in each case that such activities do not conflict with
or interfere with Mr. Lewis's obligations to the Company.  Mr. Lewis may make
personal investments in non-publicly traded corporations, partnerships or other
entities that are not engaged in any business activities competitive with the
Company.  Notwithstanding anything to the contrary contained in this Agreement,
Mr. Lewis may make personal investments in publicly traded corporations
regardless of the business they are engaged in, provided that Mr. Lewis does
not at any time own in excess of two percent (2%) of any class of the issued
and outstanding equity securities of any such corporation.

     5.   SALARY; POTENTIAL INCENTIVE COMPENSATION; ANNUAL REVIEW.  Mr. Lewis's
annual base salary for the Initial Period will be not less than $300,000.  All
base salary will be payable on the Company's regular payroll dates, less
required withholdings.

     If the Company's financial performance meets or exceeds the standards for
financial performance established for a fiscal year by the Company's Board of
Directors (i.e., the Company's "board plan"), then Mr. Lewis will be eligible
to receive, subject to such reasonably achievable incentive compensation
criteria as the Company's Board of Directors establishes from time to time,
incentive compensation (which may be in cash or other forms of consideration,
or both) of up to seventy percent (70%) of Mr. Lewis's annual base salary on
terms no less favorable than those applicable to other executive officers of
the Company (e.g., its Chairman, Vice-Chairman, Chief Executive Officer and
Chief Financial Officer).  Mr. Lewis acknowledges that the Company's Board of
Directors has complete and sole discretion to establish and revise the
Company's "board plan" and such reasonably achievable criteria; PROVIDED,
HOWEVER, that no such action may retroactively alter or limit the amount of any
incentive compensation actually and previously earned by Mr. Lewis.

     The Company, acting through its Chief Executive Officer or its Chief
Operating Officer and President or his or her respective designee, shall
provide to Mr. Lewis, and provide Mr. Lewis the opportunity to participate in,
an employment performance review not less frequently than annually.

     6.   BENEFITS.  Mr. Lewis will also be entitled to insurance, vacation and
other employee benefits commensurate with his position (and reasonably
consistent with the level of such benefits as are afforded other executive
officers of the Company) in accordance with the Company's policies in effect
from time to time with respect to executive officers.  Mr. Lewis

EMPLOYMENT AGREEMENT - Page 2
<PAGE>

acknowledges receipt of a summary of the Company's employee benefits policies
in effect as of the date of this Agreement.

     7.   REIMBURSEMENT OF NORMAL BUSINESS EXPENSES.  The Company will, in
accordance with the Company's policies in effect from time to time, reimburse
Mr. Lewis for all out-of-pocket reasonable business expenses incurred by Mr.
Lewis in connection with the performance of his duties under this Agreement,
upon submission of the required documentation required pursuant to the
Company's standard policies and record-keeping procedures.

     8.   INTELLECTUAL PROPERTY.  Simultaneously with the execution of this
Agreement, Mr. Lewis agrees to execute and deliver (if he has not done so
already) that certain Noncompetition, Property Rights and Trade Secrets
Agreement between him and the Company, a copy of which is attached to this
Agreement as ATTACHMENT A, and that certain Confidentiality Agreement between
him and the Company, a copy of which is attached to this Agreement as
ATTACHMENT B.

     9.   TERMINATION.

          (a)   BY THE COMPANY.  Notwithstanding Section 1, the Company may
terminate Mr. Lewis's employment at any time during the Initial Period, with
or without cause, upon written notice to Mr. Lewis.

          (b)   BY MR. LEWIS.  During the Initial Period, Mr. Lewis may
terminate his employment upon written notice to the Company only if the
Company is in material breach of this Agreement; PROVIDED, HOWEVER, that such
termination will become effective only upon the expiration of 30 days
following such notice and then only if the breach remains uncured as of the
effective time of such termination.  Such termination shall be deemed a
termination by the Company of Mr. Lewis's employment under Section 9(a),
without cause, for which Mr. Lewis shall have the remedy set forth in Section
9(c).

          (c)   REMEDY.  Upon termination of Mr. Lewis's employment during the
Initial Period without cause pursuant to Section 9(a), or pursuant to Section
9(b), only, (at which time he shall cease to be an employee of the Company for
all purposes), the Company will (i) thereafter pay to Mr. Lewis on the
Company's regular payroll dates and less required withholdings, base salary
(but not bonuses or other incentive compensation, for periods before or after
such termination) at the rate paid to Mr. Lewis immediately prior to such
termination for the remaining balance of the Initial Period; and (ii) provide
Mr. Lewis, for a period coterminous with such payments, with major medical
health and dental insurance reasonably comparable to employee insurance
benefits then provided to the Company's executive officers in accordance with
the Company's employee insurance benefits policies.

     If the Company terminates Mr. Lewis's employment with cause, or if Mr.
Lewis terminates his employment in circumstances constituting a breach by him
of this Agreement, then none of the foregoing post-termination payments or
insurance benefits, or any other post-termination or severance payments or
benefits, shall be made or provided to Mr. Lewis.

EMPLOYMENT AGREEMENT - Page 3
<PAGE>

     For purposes of this Agreement, the term "cause" shall mean conduct
involving one or more of the following as determined by the Company in its
reasonable discretion:  (i) the substantial, material and continuing failure of
Mr. Lewis, after reasonable notice thereof, to render services to the Company
or any subsidiary in accordance with the terms or requirements of this
Agreement; (ii) disloyalty, gross negligence, willful misconduct, dishonesty or
breach of fiduciary duty to the Company or any subsidiary that results in
direct or indirect material loss, damage or injury to the Company or any
subsidiary; (iii) the commission of an act of embezzlement or fraud; (iv)
deliberate disregard of the rules or policies of the Company that results in
direct or indirect material loss, damage or injury to the Company or any
subsidiary; (v) the unauthorized and intentional disclosure of any trade secret
or confidential information of the Company or any subsidiary; (vi) the
commission of an act that constitutes unfair competition with the Company or
any subsidiary or which induces any customer or supplier to terminate a
contract with the Company or any subsidiary, that results in direct or indirect
material loss, damage or injury to the Company or any subsidiary; (vii)
habitual drunkenness or an addiction to drugs; or (viii) commission of a crime
of moral turpitude.

     The Company's obligation to make payments (and provide insurance
benefits), if any, pursuant to this Section 9(c) is subject to the condition
that Mr. Lewis execute and deliver to the Company a comprehensive, general
release of the Company (and its directors, officers, shareholders, employees,
agents and other representatives), in form satisfactory to the Company and its
counsel, releasing the Company from and against any claims, damages and the
like that the Company might or allegedly could otherwise be obligated to pay
Mr. Lewis as a result of the termination of Mr. Lewis's employment with the
Company (including for claims of employment discrimination, wrongful
termination or breach of this Agreement).

          (d)   UPON DEATH.  Except as otherwise provided for in this
Agreement, if Mr. Lewis dies during the term of this Agreement, then the
Company will pay his estate an amount equal to all earned and unpaid salary,
bonuses (if any) accrued and payable and accrued benefits, all as of the date
of his death.

          (e)   SURVIVAL.  Mr. Lewis's and the Company's obligations under
Sections 8, 9 and 10(h) of this Agreement and, to the extent that any
allowable expenses have not been reimbursed as of the time of such
termination, under Section 7 of this Agreement, will survive the termination
of Mr. Lewis's employment with the Company.

     10.  MISCELLANEOUS.

          (a)   NOTICES.  Any and all notice permitted or required to be given
under this Agreement must be in writing.  Notices will be deemed given (i)

          (b)   AMENDMENTS.  This Agreement, including the Attachments hereto,
contains the entire agreement and supersedes and replaces all prior agreements
between the Company and Mr. Lewis concerning Mr. Lewis's employment and
employment benefits.  (PROVIDED, HOWEVER, that this Agreement does not so
supersede or replace any (i) agreements with respect to stock options
previously granted to Mr. Lewis or (ii) agreements between Mr. Lewis and the
Company, or among Mr. Lewis, the Company and others, establishing rights of
first refusal and/or similar rights with respect to such stock.)  This
Agreement may not be changed or modified in whole or in part except by a
writing signed by the party against whom enforcement of the change or
modifications is sought.

          (c)   SUCCESSORS AND ASSIGNS.  This Agreement will not be assignable
by either Mr. Lewis or the Company, except that the rights and obligations of
the Company under this Agreement may be assigned to a corporation which
succeeds the Company as the result of a

EMPLOYMENT AGREEMENT - Page 5
<PAGE>

merger or other corporate reorganization and which continues the business of
the Company, or a subsidiary of the Company, provided that the Company
guarantees the performance by such assignee of the Company's obligations
hereunder.

          (d)   GOVERNING LAW.  The laws of the State of Texas (without regard
to its choice of law principles that might apply the law of another
jurisdiction) will govern the validity of this Agreement, the construction of
its terms, and the interpretation and enforcement of the rights and duties of
the parties.

          (e)   NO WAIVER.  The failure of any party to enforce any of the
provisions of this Agreement will not be construed to be a waiver of the right
of such party thereafter to enforce such provisions.  The waiver by any party
of the right to enforce any of the provisions of this Agreement on any
occasion will not be construed to be a waiver of the right of such party to
enforce such provisions on any other occasion.

          (f)   SEVERABILITY.  Mr. Lewis and the Company recognize that the
limitations contained in this Agreement are reasonably and properly required
for the adequate protection of the interests of the Company.  If for any reason
a court of competent jurisdiction or an arbitrator in a binding arbitration
proceeding finds any provision of this Agreement, or the application thereof,
to be unenforceable, then the remaining provisions of this Agreement will be
interpreted so as best to reasonably effect the intent of the parties.  The
parties further agree that the court or arbitrator shall replace any such
invalid or unenforceable provisions with valid and enforceable provisions
designed to achieve, to the extent possible, the business purposes and intent
of such unenforceable provisions.

          (g)   COUNTERPARTS.  This Agreement may be executed in counterparts,
each of which will be an original as regards any party whose signature appears
thereon and all of which together will constitute one and the same instrument.
This Agreement will become binding when one or more counterparts hereof,
individually or taken together, bear the signatures of both parties reflected
hereon as signatories.

          (h)   DISPUTE RESOLUTION.

               (i)   ARBITRATION OF DISPUTES.  Any dispute under this
Agreement shall be resolved by arbitration in Dallas, Texas and, except as
herein specifically stated, in accordance with the commercial arbitration
rules of the American Arbitration Association ("AAA RULES") then in effect,
except that depositions and documentary discovery shall be freely permitted.
However, in all events, these arbitration provisions shall govern over any
conflicting rules that may now or hereafter be contained in the AAA Rules.
Any judgment upon the award rendered by the arbitrator may be entered in any
court having jurisdiction over the subject matter thereof.  The arbitrator
shall have the authority to grant any equitable and legal remedies that would
be available in any judicial proceeding instituted to resolve such dispute,
and may, in his or her discretion, award attorneys' fees, expenses and costs.

               (ii)  COMPENSATION OF ARBITRATOR.  Any such arbitration will be
conducted before a single arbitrator who will be compensated for his or her
services at a rate to be

EMPLOYMENT AGREEMENT - Page 6
<PAGE>

determined by the parties or by the American Arbitration Association, but
based upon reasonable hourly or daily consulting rates for the arbitrator if
the parties are not able to agree upon his or her rate of compensation.

               (iii)  SELECTION OF ARBITRATOR.  The American Arbitration
Association will have the authority to select an arbitrator from a list of
arbitrators who are lawyers familiar with Texas contract law; PROVIDED,
HOWEVER, that such lawyers cannot work for a firm then performing services for
either party, that each party will have the opportunity to make such
reasonable objection to any of the arbitrators listed as such party may wish
and that the American Arbitration Association will select the arbitrator from
the list of arbitrators as to whom neither party makes any such objection.  If
the foregoing procedure is not followed, then each party will choose one
person from the list of arbitrators provided by the American Arbitration
Association (provided that such person does not have a conflict of interest),
and the two persons so selected will select from the list provided by the
American Arbitration Association the person who will act as the arbitrator.

               (iv)   PAYMENT OF COSTS.  Subject to the last sentence of
Section 10(h)(i) above, the Company and Mr. Lewis will each pay 50% of the
initial compensation to be paid to the arbitrator in any such arbitration and
50% of the costs of transcripts and other normal and regular expenses of the
arbitration proceedings.

               (v)    BURDEN OF PROOF.  For any dispute submitted to
arbitration, the burden of proof will be as it would be if the claim were
litigated in a Texas judicial proceeding.

               (vi)   AWARD.  Upon the conclusion of any arbitration
proceedings hereunder, the arbitrator will render findings of fact and
conclusions of law and a written opinion setting forth the basis and reasons
for any decision reached and will deliver such documents to each party to this
Agreement along with a signed copy of the award.

               (vii)  TERMS OF ARBITRATION.  The arbitrator chosen in
accordance with these provisions will not have the power to alter, amend or
otherwise affect the terms of these arbitration provisions or the provisions
of this Agreement.

               (viii) NATURE OF REMEDY.  Except as specifically otherwise
provided below, arbitration will be the sole and exclusive remedy of the
parties for any dispute arising out of this Agreement.

               (ix)   EQUITABLE REMEDY.  Notwithstanding the provisions of
this Section 10(h) and the arbitration provided for herein, actions initiated
or maintained by the parties for injunctive or similar equitable relief are
not subject to arbitration, and may be brought by the parties in any court
that has jurisdiction, and, should the party bringing any such action prevail,
all costs and expenses (including legal fees) shall be borne by the party
against whom such action was brought.

                                 EMPLOYMENT AGREEMENT

     This EMPLOYMENT AGREEMENT (this "AGREEMENT") is entered into on this 10th
day of March 1998, to be effective for all purposes as of December 15, 1996,
between Carreker-Antinori, Inc., a Texas corporation formerly named The Carreker
Group, Inc. (the "COMPANY"), and Richard L. Linting ("MR. LINTING").

                                       RECITALS

     Mr. Linting commenced employment by the Company effective December 15,
1996, pursuant to a letter agreement between Mr. Linting and the Company dated
December 18, 1996.

     This Agreement sets forth in definitive form the terms of Mr. Linting's
employment by the Company.  As such, this Agreement supersedes the letter
agreement in its entirety.

     NOW, THEREFORE, in consideration of the foregoing and the mutual agreements
of the parties contained herein, the Company and Mr. Linting hereby agree as
follows:

     1.   EMPLOYMENT.  The Company will employ Mr. Linting and Mr. Linting
accepts employment with the Company for a period of three years beginning
December 15, 1996 (the "INITIAL PERIOD").  Mr. Linting's employment may continue
after the Initial Period but will then be terminable by either party at will,
with or without cause; PROVIDED, HOWEVER, that during such "at will" period, the
Company may terminate Mr. Linting's employment only after providing Mr. Linting
not less than two weeks prior notice of such termination; PROVIDED FURTHER,
HOWEVER, that during such "at will" period the Company need not provide such two
weeks prior notice if such termination is for cause.  The obligations of the
Company and Mr. Linting set forth in that certain "Noncompetition, Property
Rights and Trade Secrets Agreement" and in that certain "Confidentiality
Agreement" (each as defined in Section 8) (referring to noncompetition,
intellectual property rights and confidentiality, respectively) and in Section 9
(referring to termination) will survive termination of Mr. Linting's employment,
regardless of reason.

     During the period of the Company's employment of Mr. Linting, the Company
shall use its reasonable best efforts to nominate and secure the election of Mr.
Linting to the Company's Board of Directors and any executive or similar
committee of the Company's Board of Directors.  Mr. Linting acknowledges that
the Company does not have the right, by itself, to secure such election, and
also that a director's fiduciary duty, and possibly in certain cases a
shareholder's fiduciary duty, in either case exercised in good faith, may in
remote circumstances preclude such election, in which event the Company's
obligations set forth in the foregoing sentence shall not be deemed breached.  

     2.   RESIDENCE AND BUSINESS TRAVEL.  The Company acknowledges that Mr.
Linting intends to maintain his principal residence in Bozeman, Montana during
the Initial Period.  Mr. Linting acknowledges and agrees that the primary
location of his employment will be in Dallas, Texas or its environs, that he
will spend substantial time in Dallas, Texas and other locations where the
Company transacts (or proposes to transact) business and undertake such business
travel 

<PAGE>

as is reasonably required in the discharge of his duties set forth below and 
for the successful operation of the Company.

     3.   DUTIES.  Mr. Linting was employed initially as the President and Chief
Operating Officer of the Company's consulting and management services group. 
The parties acknowledge that, subsequent to the effective date of this
Agreement, Mr. Linting was elected to serve as the President and Chief Operating
Officer of the Company.  With the exception of certain administrative
responsibilities currently handled by Mr. Terry Gage, Mr. Linting shall be
responsible for the operation of the Company's consulting and management
services group and software group, and shall have such authority as is
reasonably necessary to perform his duties.  

     Mr. Linting agrees that, to the best of his ability and experience, he will
at all times conscientiously perform such duties and obligations as may be
assigned to him, consistent with his position, by the Company's Chief Executive
Officer or the Company's Board of Directors.

     4.   FULL-TIME EMPLOYMENT.  Mr. Linting's employment will be on a full-time
basis, in accordance with standard employee policies of the Company.  In
addition to such restrictions as are set forth in the Noncompetition, Property
Rights and Trade Secrets Agreement referenced herein, Mr. Linting will not
engage in any other business or render any commercial or professional services,
directly or indirectly, to any other person or organization, whether for
compensation or otherwise, provided that Mr. Linting may (a) provide incidental
assistance to family members on matters of family business; (b) engage in
charitable activities on behalf of civic, educational or other nonprofit
organizations; and (c) subject to the approval of the Company's Chief Executive
Officer, sit on the board of directors of corporations and other business
organizations that, in any and all cases, do not compete with the Company;
provided in each case that such activities do not conflict with or interfere
with Mr. Linting's normal full-time and first priority obligations to the
Company.  Mr. Linting may make personal investments in non-publicly traded
corporations, partnerships or other entities that, to the knowledge of the
Company, are not at the time of such investment engaged in any business
activities competitive with the Company.  Notwithstanding anything to the
contrary contained in this Agreement, Mr. Linting may make personal investments
in publicly traded corporations regardless of the business they are engaged in,
provided that Mr. Linting does not at any time own in excess of two percent (2%)
of the issued and outstanding stock of any such corporation.

     5.   SALARY; POTENTIAL INCENTIVE COMPENSATION; STOCK OPTIONS.

          (a)  SALARY AND POTENTIAL INCENTIVE COMPENSATION.  Mr. Linting's
annual base salary for the Initial Period will be not less than $350,000.  All
base salary will be payable on the Company's regular payroll dates, less
required withholdings.

     If the Company's financial performance meets or exceeds the standards for
financial performance established for a fiscal year by the Company's Board of
Directors (i.e., the Company's "board plan"), then Mr. Linting will be eligible
to receive, subject to such reasonably achievable incentive compensation
criteria as the Company's Board of Directors establishes from time to time
(which criteria shall take into consideration that Mr. Linting's
responsibilities 


EMPLOYMENT AGREEMENT - Page 2

<PAGE>

increased during the fiscal year ending January 31, 1998), incentive 
compensation equal to seventy percent (70%) of Mr. Linting's annual base 
salary on terms no less favorable than those applicable to other high level 
officers of the Company (e.g., its Chairman, Vice-Chairman, Chief Executive 
Officer and Chief Financial Officer).  Mr. Linting acknowledges that the 
Company's Board of Directors has complete and sole discretion (exercisable in 
good faith) to establish and revise the Company's "board plan" and such 
reasonably achievable criteria; PROVIDED, HOWEVER, that no such action may 
retroactively alter or limit the amount of any incentive compensation 
actually and previously earned by Mr. Linting.  

          (b)  STOCK OPTIONS.  The Company has heretofore granted, effective as
of December 15, 1996, Mr. Linting options to purchase up to 40,000 shares of the
Company's Class B Non-Voting Common Stock at an exercise price of $19.87 per
share.  Such options, which are incentive stock options with respect to 15,000
shares and non-qualified options with respect to 25,000 shares, shall each vest
one-third as of the effective day of the grant, one-third on December 15, 1997
and the remaining one-third on December 15, 1998.  The Company has also
heretofore granted, effective as of August 1, 1997, Mr. Linting options to
purchase up to 20,000 shares of the Company's Class B Non-Voting Common Stock at
an exercise price of $28.26 per share.  Such options, which are non-qualified
options, shall each vest one-third as of the effective day of the grant,
one-third on August 1, 1998, and the remaining one-third on August 1, 1999.  All
unvested options shall vest immediately, however, upon the occurrence of any of
the following:  a Change of Control (as defined below), the termination by the
Company of Mr. Linting's employment without cause, Mr. Linting's resignation
pursuant to Section 9(b) of this Agreement, Mr. Linting's permanent disability,
or Mr. Linting's death.  Each such option shall be issued under and pursuant to
the Company's 1994 Amended and Restated Long Term Incentive Plan, with terms and
conditions as provided therein except as expressly provided herein.  In addition
to the above stock options, Mr. Linting may also be eligible to receive such
other options that the Company's Board of Directors shall, in its sole
discretion, hereafter determine to grant to him.

     For purposes of this Agreement, a Change of Control shall have occurred if,
as the result of a completed tender offer, merger, consolidation, sale of
assets, acquisition of shares or contested election, or any combination of the
foregoing transactions, (a) any person (other than J.D. Carreker, his heirs,
Crow Family Partnership, L.P., Science Applications International Corporation or
affiliates of any of them) shall become the owner, beneficially or of record, of
more than fifty percent (50%) of the aggregate voting power of the Company, or
(b) during any period of two consecutive years, individuals who at the beginning
of such period constituted the Board of Directors of the Company (together with
any new directors whose election to such board or whose nomination for election
by the shareholders of the Company was approved by the directors then still in
office who were either directors at the beginning of such period or whose
election or nomination for election was previously so approved) cease to
constitute a majority of the Board of Directors of the Company.

     6.   BENEFITS.  Mr. Linting will also be entitled to insurance, vacation
and other employee benefits commensurate with his position (and reasonably
consistent with the level of such benefits as are afforded the Chairman of the
Company) in accordance with the Company's standard employee policies in effect
from time to time.  Mr. Linting acknowledges receipt of a 


EMPLOYMENT AGREEMENT - Page 3

<PAGE>

summary of the Company's standard employee benefits policies in effect as of 
the date of this Agreement.

     7.   REIMBURSEMENT OF SPECIAL EXPENSES AND NORMAL BUSINESS EXPENSES.  The
Company agrees to reimburse Mr. Linting in an aggregate amount of up to $48,000
per year (with each such year commencing on December 15th) for his out-of-pocket
expenses incurred in connection with an apartment in Dallas, Texas with health
club facilities, an automobile and furnishings. 

     Mr. Linting's expenses incurred in travelling to and from Bozeman, Montana,
Laguna Beach, California or any other primary or secondary residences of Mr.
Linting (each, a "residence") shall be reimbursed to Mr. Linting only to the
extent that, in connection with travel on Company business, airfare expenses
incurred by Mr. Linting in (a) such travel that includes making an intermediate
stop (i.e., a "layover") in such residence do not exceed the comparable airfare
expenses that would have been incurred BUT FOR the intermediate stop and (b)
round-trip travel from a residence to a location other than Dallas, Texas do not
exceed comparable airfare expenses of round-trip travel to such location from
Dallas, Texas.

     The Company will, but in accordance with the Company's policies in effect
from time to time, reimburse Mr. Linting for all other out-of-pocket reasonable
business expenses incurred by Mr. Linting in connection with the performance of
his duties under this Agreement upon submission of the required documentation
required pursuant to the Company's standard policies and record-keeping
procedures.

     8.   INTELLECTUAL PROPERTY.  Simultaneously with the execution of this
Agreement, Mr. Linting agrees to execute and deliver that certain
Noncompetition, Property Rights and Trade Secrets Agreement between him and the
Company, a copy of which is attached to this Agreement as ATTACHMENT A, and that
certain Confidentiality Agreement between him and the Company, a copy of which
is attached to this Agreement as ATTACHMENT B.

     9.   TERMINATION.

          (a)  THE COMPANY.  Notwithstanding Section 1, the Company may
terminate Mr. Linting's employment at any time during the Initial Period with or
without cause upon written notice to Mr. Linting.

          (b)  BY MR. LINTING.  During the Initial Period, Mr. Linting may
terminate his employment upon written notice to the Company if the Company is
then in material breach of this Agreement; provided, however, that such material
breach shall permit such termination only if the Company shall have been
provided at least 30 days' prior notice and opportunity to cure such material
breach.  Any such termination shall be deemed a termination by the Company of
Mr. Linting's employment under Section 9(a) for which Mr. Linting shall have the
remedy set forth in Section 9(c).

          (c)  REMEDY.  Upon termination of Mr. Linting's employment during the
Initial Period without cause pursuant to Section 9(a) or pursuant to Section
9(b) only (at which time he 


EMPLOYMENT AGREEMENT - Page 4

<PAGE>

shall cease to be an employee of the Company for all purposes), the Company 
will (i) pay to Mr. Linting, for two years, on the Company's regular payroll 
dates and less required withholdings, base salary at the rate paid to Mr. 
Linting immediately prior to such termination; (ii) provide Mr. Linting, for 
a period coterminous with such payments, with major medical health and dental 
insurance reasonably comparable to employee benefits then provided to the 
Company's senior officers in accordance with the Company's standard employee 
benefits policies; and (iii) pay to Mr. Linting, as and when the same would 
be otherwise payable, any incentive compensation for the balance of the 
Initial Period based on incentive compensation criteria that, prior to or on 
the date of termination, have been established by the Company's Board of 
Directors, determined as to amount as if Mr. Linting had remained an employee 
of the Company hereunder.  Without limiting the foregoing sentence, the 
$48,000 per year reimbursement allowance provided for above shall not survive 
termination. In addition to the benefits described above, all stock options 
granted to Mr. Linting in accordance with Section 5(b) shall become fully 
vested and, subject to their stated term, exercisable on and after such date 
of termination of employment (whether or not previously vested or 
exercisable).

     If the Company terminates Mr. Linting's employment with cause, then none of
the foregoing post-termination payments or benefits, or any other 
post-termination or severance payments or benefits, shall be made or provided 
to Mr. Linting.

     For purposes of this Agreement, the term "cause" shall mean conduct
involving one or more of the following as determined by the Company in its
reasonable discretion:  (i) the substantial, material and continuing failure of
Mr. Linting, after reasonable notice thereof, to render services to the Company
or any subsidiary in accordance with the terms or requirements of this
Agreement; (ii) disloyalty, gross negligence, willful misconduct, dishonesty or
breach of fiduciary duty to the Company or any subsidiary that results in direct
or indirect material loss, damage or injury to the Company or any subsidiary;
(iii) the commission of an act of embezzlement or fraud; (iv) deliberate
disregard of the rules or policies of the Company that results in direct or
indirect material loss, damage or injury to the Company or any subsidiary; (v)
the unauthorized and intentional disclosure of any trade secret or confidential
information of the Company or any subsidiary; (vi) the commission of an act that
constitutes unfair competition with the Company or any subsidiary or which
induces any customer or supplier to terminate a contract with the Company or any
subsidiary, that results in direct or indirect material loss, damage or injury
to the Company or any subsidiary; (vii) habitual drunkenness or an addiction to
drugs; or (viii) commission of a crime of moral turpitude.

     The Company's obligation to make payments (and provide benefits), if any,
pursuant to this Section 9(c) is in lieu of any damages and any other payment or
other benefits that the Company might otherwise be obligated to pay Mr. Linting
as a result of the termination of Mr. Linting's employment with the Company
(including for claims of employment discrimination, wrongful termination or
breach of this Section 9).  The Company and Mr. Linting agree that, in view of
the nature of the issues likely to arise in the event of such a termination, it
would be impracticable or extremely difficult to fix the actual damages
resulting from such termination and proving actual damages, causation and
foreseeability in the case of such termination would be costly, inconvenient and
difficult.  In requiring the Company to make the payments (and provide the
benefits) as set forth herein, it is the intent of the parties to provide, as of
the date of this 


EMPLOYMENT AGREEMENT - Page 5

<PAGE>

Agreement, for a liquidated amount of damages to be paid by the Company to 
Mr. Linting.  Such liquidated amount shall be deemed full and adequate 
damages for such termination and is not intended by either party to be a 
penalty.

          (d)  UPON DEATH.  Except as otherwise provided for in this Agreement,
if Mr. Linting dies during the term of this Agreement, then the Company will pay
his estate an amount equal to all earned and unpaid salary, bonuses (if any)
accrued and payable and accrued benefits, all as of the date of his death.

          (e)  RESIGNATION AS DIRECTOR.  If Mr. Linting ceases to be a full-time
employee of the Company when he is serving as a director of the Company, then
Mr. Linting agrees to promptly resign as a director of the Company.

          (f)  SURVIVAL.  Mr. Linting's and the Company's obligations under
Sections 8, 9 and 12(h) of this Agreement and, to the extent that any
reimbursable expenses have not been reimbursed as of the time of such
termination, under Section 7 of this Agreement, will survive the termination of
Mr. Linting's employment with the Company.

     10.  OTHER PAYMENTS.  The Company will reimburse Mr. Linting for reasonable
out-of-pocket expenses incurred in moving his furnishings from his residence in
Montana or California to the Dallas, Texas area.  In addition, the Company will
reimburse Mr. Linting for up to $5,000 in legal fees in connection with (a) the
review of the letter agreement referenced in the recitals to this Agreement, the
Company's benefits and compensation plans and the documentation relating to the
merger between the Company and Antinori Software, Inc. and (b) the review and
negotiation of this Agreement.

     11.  FUTURE SHARE SALES.  The Company agrees to take into consideration in
any sale of the Company's capital stock the valuations and projections reviewed
prior to December 18, 1996 by Mr. Linting and Mr. J.D. Carreker; PROVIDED,
HOWEVER, that Mr. Linting acknowledges that (a) such valuations and projections,
although prepared in good faith, were based on reasonable assumptions in light
of conditions in effect on the date prepared and (b) that such valuations and
projections and this Section 11 do not constitute a representation, warranty or
create any obligation of the Company with respect to the value or future value
of shares of the Company's capital stock.

     12.  MISCELLANEOUS.

          (a)  NOTICES.  Any and all notice permitted or required to be given
under this Agreement must be in writing.  Notices will be deemed given (i) when
personally received or when sent by facsimile transmission (to the receiving
party's facsimile number), (ii) on the first business day after having been sent
by commercial overnight courier with written verification of receipt, or (iii)
on the third business day after having been sent by registered or certified mail
from a location on the United States mainland, return receipt requested, postage
prepaid, whichever occurs first, at the address set forth below or at any new

EMPLOYMENT AGREEMENT - Page 7

<PAGE>

          (d)  GOVERNING LAW.  The laws of the State of Texas (without regard to
its choice of law principles that might apply the law of another jurisdiction)
will govern the validity of this Agreement, the construction of its terms, and
the interpretation and enforcement of the rights and duties of the parties.

          (e)  NO WAIVER.  The failure of any party to enforce any of the
provisions of this Agreement will not be construed to be a waiver of the right
of such party thereafter to enforce such provisions.  The waiver by any party of
the right to enforce any of the provisions of this Agreement on any occasion
will not be construed to be a waiver of the right of such party to enforce such
provisions on any other occasion.

          (f)  SEVERABILITY.  Mr. Linting and the Company recognize that the
limitations contained in this Agreement are reasonably and properly required for
the adequate protection of the interests of the Company.  If for any reason a
court of competent jurisdiction or an arbitrator in a binding arbitration
proceeding finds any provision of this Agreement, or the application thereof, to
be unenforceable, then the remaining provisions of this Agreement will be
interpreted so as best to reasonably effect the intent of the parties.  The
parties further agree that the court or arbitrator shall replace any such
invalid or unenforceable provisions with valid and enforceable provisions
designed to achieve, to the extent possible, the business purposes and intent of
such unenforceable provisions.

          (g)  COUNTERPARTS.  This Agreement may be executed in counterparts,
each of which will be an original as regards any party whose signature appears
thereon and all of which together will constitute one and the same instrument. 
This Agreement will become binding when one or more counterparts hereof,
individually or taken together, bear the signatures of both parties reflected
hereon as signatories.

          (h)  DISPUTE RESOLUTION.

               (i)    ARBITRATION OF DISPUTES.  Any dispute under this
Agreement shall be resolved by arbitration in Dallas, Texas and, except as
herein specifically stated, in accordance with the commercial arbitration rules
of the American Arbitration Association ("AAA RULES") then in effect.  However,
in all events, these arbitration provisions shall govern over any conflicting
rules that may now or hereafter be contained in the AAA Rules.  Any judgment
upon the award rendered by the arbitrator may be entered in any court having
jurisdiction over the subject matter thereof.  The arbitrator shall have the
authority to grant any equitable and legal remedies that would be available in
any judicial proceeding instituted to resolve such dispute, and may, in his or
her discretion, award attorneys' fees, expenses and costs.

               (ii)   COMPENSATION OF ARBITRATOR.  Any such arbitration will be
conducted before a single arbitrator who will be compensated for his or her
services at a rate to be determined by the parties or by the American
Arbitration Association, but based upon reasonable hourly or daily consulting
rates for the arbitrator if the parties are not able to agree upon his or her
rate of compensation.


EMPLOYMENT AGREEMENT - Page 8

<PAGE>

               (iii)  SELECTION OF ARBITRATOR.  The American Arbitration
Association will have the authority to select an arbitrator from a list of
arbitrators who are lawyers familiar with Texas contract law; PROVIDED, HOWEVER,
that such lawyers cannot work for a firm then performing services for either
party, that each party will have the opportunity to make such reasonable
objection to any of the arbitrators listed as such party may wish and that the
American Arbitration Association will select the arbitrator from the list of
arbitrators as to whom neither party makes any such objection.  If the foregoing
procedure is not followed, then each party will choose one person from the list
of arbitrators provided by the American Arbitration Association (provided that
such person does not have a conflict of interest), and the two persons so
selected will select from the list provided by the American Arbitration
Association the person who will act as the arbitrator.

               (iv)   PAYMENT OF COSTS.  The Company and Mr. Linting will each
pay 50% of the initial compensation to be paid to the arbitrator in any such
arbitration and 50% of the costs of transcripts and other normal and regular
expenses of the arbitration proceedings.

               (v)    BURDEN OF PROOF.  For any dispute submitted to
arbitration, the burden of proof will be as it would be if the claim were
litigated in a Texas judicial proceeding.

               (vi)   AWARD.  Upon the conclusion of any arbitration
proceedings hereunder, the arbitrator will render findings of fact and
conclusions of law and a written opinion setting forth the basis and reasons for
any decision reached and will deliver such documents to each party to this
Agreement along with a signed copy of the award.

               (vii)  TERMS OF ARBITRATION.  The arbitrator chosen in
accordance with these provisions will not have the power to alter, amend or
otherwise affect the terms of these arbitration provisions or the provisions of
this Agreement.

               (viii) NATURE OF REMEDY.  Except as specifically otherwise
provided below, arbitration will be the sole and exclusive remedy of the parties
for any dispute arising out of this Agreement.

               (ix)   EQUITABLE REMEDY.  Notwithstanding the provisions of this
Section 12(h) and the arbitration provided for herein, actions initiated or
maintained by the parties for injunctive or similar equitable relief are not
subject to arbitration, and may be brought by the parties in any court that has
jurisdiction, and, should the party bringing any such action prevail, all costs
and expenses (including legal fees) shall be borne by the party against whom
such action was brought.

                              EMPLOYMENT AGREEMENT

     This EMPLOYMENT AGREEMENT (this "AGREEMENT") is entered into on this 13th 
day of March 1998 between Carreker-Antinori, Inc., a Texas corporation (the 
"COMPANY"), and Royce Brown ("MR. BROWN").

                                   RECITALS

     This Agreement sets forth in definitive form the terms of Mr. Brown's 
employment by the Company.

     NOW, THEREFORE, in consideration of the foregoing and the mutual 
agreements of the parties contained herein, the Company and Mr. Brown hereby 
agree as follows:

     1.   EMPLOYMENT.  The Company will employ Mr. Brown and Mr. Brown 
accepts employment with the Company for a period of three years beginning on 
the date of this Agreement (the "INITIAL PERIOD").  Mr. Brown's employment 
may continue after the Initial Period but will then be terminable by either 
party at will, with or without cause.  The obligations of the Company and Mr. 
Brown set forth in that certain "Noncompetition, Property Rights and Trade 
Secrets Agreement" and in that certain "Confidentiality Agreement" (each as 
defined in Section 8) (referring to noncompetition, intellectual property 
rights and confidentiality, respectively) and in Section 9 (referring to 
termination) will survive termination of Mr. Brown's employment, regardless 
of reason.

     2.   RESIDENCE AND BUSINESS TRAVEL.  Each of the parties agrees that the 
primary location at which Mr. Brown will be expected to render services 
hereunder will be in Dallas, Texas or its environs, but that Mr. Brown will, 
from time to time, be expected to travel to other locations where the Company 
transacts (or proposes to transact) business and undertake such other 
business travel as is reasonably required in the discharge of his duties set 
forth below and for the successful operation of the Company.

     3.   DUTIES.  As of the date of this Agreement, Mr. Brown is employed as

Group of the Company.    

     Mr. Brown agrees that, to the best of his ability and experience, he 
will at all times conscientiously (a) perform the foregoing duties and 
responsibilities, or such other or additional duties and responsibilities, 
and/or (b) hold such other or additional offices, as in either case may be 
assigned to him from time to time by the Company's Chief Executive Officer, 
the Company's President and Chief Operating Officer or the Company's Board of 
Directors.  

     In discharging his duties, Mr. Brown shall have such authority as is 
reasonably necessary to perform such duties.

     4.   FULL-TIME EMPLOYMENT.  Mr. Brown's employment will be on a 
full-time basis, in accordance with policies of the Company applicable to 
executive officers.  In addition to such restrictions as are set forth in the 
Noncompetition, Property Rights and Trade Secrets Agreement referenced 
herein, Mr. Brown will not engage in any other business or render any 
commercial or professional services, directly or indirectly, to any other 
person or organization, whether for compensation or otherwise, provided that 
Mr. Brown may (a) provide incidental assistance to family members on matters 
of family business or with respect to their personal investments; (b) engage 
in charitable activities on behalf of civic, educational or other nonprofit 
organizations; and (c) subject to the approval of the Company's Chief 
Executive Officer (which approval may be given or withheld in his or her sole 
discretion), sit on the board of directors of corporations and other business 
organizations; provided in each case that such activities do not conflict 
with or interfere with Mr. Brown's obligations to the Company.  Mr. Brown may 
make personal investments in non-publicly traded corporations, partnerships 
or other entities that are not engaged in any business activities competitive 
with the Company. Notwithstanding anything to the contrary contained in this 
Agreement, Mr. Brown may make personal investments in publicly traded 
corporations regardless of the business they are engaged in, provided that 
Mr. Brown does not at any time own in excess of two percent (2%) of any class 
of the issued and outstanding equity securities of any such corporation.

     5.   SALARY; POTENTIAL INCENTIVE COMPENSATION; ANNUAL REVIEW.  Mr. 
Brown's annual base salary for the Initial Period will be not less than 
$240,000.  All base salary will be payable on the Company's regular payroll 
dates, less required withholdings.

     If the Company's financial performance meets or exceeds the standards 
for financial performance established for a fiscal year by the Company's 
Board of Directors (i.e., the Company's "board plan"), then Mr. Brown will be 
eligible to receive, subject to such reasonably achievable incentive 
compensation criteria as the Company's Board of Directors establishes from 
time to time, incentive compensation (which may be in cash or other forms of 
consideration, or both) of up to seventy percent (70%) of Mr. Brown's annual 
base salary on terms no less favorable than those applicable to other 
executive officers of the Company (e.g., its Chairman, Vice-Chairman, Chief 
Executive Officer and Chief Financial Officer).  Mr. Brown acknowledges that 
the Company's Board of Directors has complete and sole discretion to 
establish and revise the Company's "board plan" and such reasonably 
achievable criteria; PROVIDED, HOWEVER, that no such action may retroactively 
alter or limit the amount of any incentive compensation actually and 
previously earned by Mr. Brown.  

     The Company, acting through its Chief Executive Officer or its Chief 
Operating Officer and President or his or her respective designee, shall 
provide to Mr. Brown, and provide Mr. Brown the opportunity to participate 
in, an employment performance review not less frequently than annually. 

     6.   BENEFITS.  Mr. Brown will also be entitled to insurance, vacation 
and other employee benefits commensurate with his position (and reasonably 
consistent with the level of such benefits as are afforded other executive 
officers of the Company) in accordance with the Company's policies in effect 
from time to time with respect to executive officers.  Mr. Brown 

EMPLOYMENT AGREEMENT - Page 2
<PAGE>

acknowledges receipt of a summary of the Company's employee benefits policies 
in effect as of the date of this Agreement.

     7.   REIMBURSEMENT OF NORMAL BUSINESS EXPENSES.  The Company will, in 
accordance with the Company's policies in effect from time to time, reimburse 
Mr. Brown for all out-of-pocket reasonable business expenses incurred by Mr. 
Brown in connection with the performance of his duties under this Agreement, 
upon submission of the required documentation required pursuant to the 
Company's standard policies and record-keeping procedures.

     8.   INTELLECTUAL PROPERTY.  Simultaneously with the execution of this 
Agreement, Mr. Brown agrees to execute and deliver (if he has not done so 
already) that certain Noncompetition, Property Rights and Trade Secrets 
Agreement between him and the Company, a copy of which is attached to this 
Agreement as ATTACHMENT A, and that certain Confidentiality Agreement between 
him and the Company, a copy of which is attached to this Agreement as 
ATTACHMENT B.

     9.   TERMINATION.

          (a)  BY THE COMPANY.  Notwithstanding Section 1, the Company may 
terminate Mr. Brown's employment at any time during the Initial Period, with 
or without cause, upon written notice to Mr. Brown.

          (b)  BY MR. BROWN.  During the Initial Period, Mr. Brown may 
terminate his employment upon written notice to the Company only if the 
Company is in material breach of this Agreement; PROVIDED, HOWEVER, that such 
termination will become effective only upon the expiration of 30 days 
following such notice and then only if the breach remains uncured as of the 
effective time of such termination.  Such termination shall be deemed a 
termination by the Company of Mr. Brown's employment under Section 9(a), 
without cause, for which Mr. Brown shall have the remedy set forth in Section 
9(c).

          (c)  REMEDY.  Upon termination of Mr. Brown's employment during the 
Initial Period without cause pursuant to Section 9(a), or pursuant to Section 
9(b), only, (at which time he shall cease to be an employee of the Company 
for all purposes), the Company will (i) thereafter pay to Mr. Brown on the 
Company's regular payroll dates and less required withholdings, base salary 
(but not bonuses or other incentive compensation, for periods before or after 
such termination) at the rate paid to Mr. Brown immediately prior to such 
termination for the remaining balance of the Initial Period; and (ii) provide 
Mr. Brown, for a period coterminous with such payments, with major medical 
health and dental insurance reasonably comparable to employee insurance 
benefits then provided to the Company's executive officers in accordance with 
the Company's employee insurance benefits policies.

     If the Company terminates Mr. Brown's employment with cause, or if Mr. 
Brown terminates his employment in circumstances constituting a breach by him 
of this Agreement, then none of the foregoing post-termination payments or 
insurance benefits, or any other post-termination or severance payments or 
benefits, shall be made or provided to Mr. Brown.

     For purposes of this Agreement, the term "cause" shall mean conduct 
involving one or more of the following as determined by the Company in its 
reasonable discretion:  (i) the substantial, material and continuing failure 
of Mr. Brown, after reasonable notice thereof, to render services to the 
Company or any subsidiary in accordance with the terms or requirements of 
this Agreement; (ii) disloyalty, gross negligence, willful misconduct, 
dishonesty or breach of fiduciary duty to the Company or any subsidiary that 
results in direct or indirect material loss, damage or injury to the Company 
or any subsidiary; (iii) the commission of an act of embezzlement or fraud; 
(iv) deliberate disregard of the rules or policies of the Company that 
results in direct or indirect material loss, damage or injury to the Company 
or any subsidiary; (v) the unauthorized and intentional disclosure of any 
trade secret or confidential information of the Company or any subsidiary; 
(vi) the commission of an act that constitutes unfair competition with the 
Company or any subsidiary or which induces any customer or supplier to 
terminate a contract with the Company or any subsidiary, that results in 
direct or indirect material loss, damage or injury to the Company or any 
subsidiary; (vii) habitual drunkenness or an addiction to drugs; or (viii) 
commission of a crime of moral turpitude.

     The Company's obligation to make payments (and provide insurance 
benefits), if any, pursuant to this Section 9(c) is subject to the condition 
that Mr. Brown execute and deliver to the Company a comprehensive, general 
release of the Company (and its directors, officers, shareholders, employees, 
agents and other representatives), in form satisfactory to the Company and 
its counsel, releasing the Company from and against any claims, damages and 
the like that the Company might or allegedly could otherwise be obligated to 
pay Mr. Brown as a result of the termination of Mr. Brown's employment with 
the Company (including for claims of employment discrimination, wrongful 
termination or breach of this Agreement).

          (d)  UPON DEATH.  Except as otherwise provided for in this 
Agreement, if Mr. Brown dies during the term of this Agreement, then the 
Company will pay his estate an amount equal to all earned and unpaid salary, 
bonuses (if any) accrued and payable and accrued benefits, all as of the date 
of his death.

          (e)  SURVIVAL.  Mr. Brown's and the Company's obligations under 
Sections 8, 9 and 10(h) of this Agreement and, to the extent that any 
allowable expenses have not been reimbursed as of the time of such 
termination, under Section 7 of this Agreement, will survive the termination 
of Mr. Brown's employment with the Company.

          (b)  AMENDMENTS.  This Agreement, including the Attachments hereto, 
contains the entire agreement and supersedes and replaces all prior 
agreements between the Company and Mr. Brown concerning Mr. Brown's 
employment and employment benefits.  (PROVIDED, HOWEVER, that this Agreement 
does not so supersede or replace any (i) agreements with respect to stock 
options previously granted to Mr. Brown or (ii) agreements between Mr. Brown 
and the Company, or among Mr. Brown, the Company and others, establishing 
rights of first refusal and/or similar rights with respect to such stock.)  
This Agreement may not be changed or modified in whole or in part except by a 
writing signed by the party against whom enforcement of the change or 
modifications is sought.

          (c)  SUCCESSORS AND ASSIGNS.  This Agreement will not be assignable 
by either Mr. Brown or the Company, except that the rights and obligations of 
the Company under this Agreement may be assigned to a corporation which 
succeeds the Company as the result of a 

EMPLOYMENT AGREEMENT - Page 5
<PAGE>

merger or other corporate reorganization and which continues the business of 
the Company, or a subsidiary of the Company, provided that the Company 
guarantees the performance by such assignee of the Company's obligations 
hereunder.

          (d)  GOVERNING LAW.  The laws of the State of Texas (without regard 
to its choice of law principles that might apply the law of another 
jurisdiction) will govern the validity of this Agreement, the construction of 
its terms, and the interpretation and enforcement of the rights and duties of 
the parties.

          (e)  NO WAIVER.  The failure of any party to enforce any of the 
provisions of this Agreement will not be construed to be a waiver of the 
right of such party thereafter to enforce such provisions.  The waiver by any 
party of the right to enforce any of the provisions of this Agreement on any 
occasion will not be construed to be a waiver of the right of such party to 
enforce such provisions on any other occasion.

          (f)  SEVERABILITY.  Mr. Brown and the Company recognize that the 
limitations contained in this Agreement are reasonably and properly required 
for the adequate protection of the interests of the Company.  If for any 
reason a court of competent jurisdiction or an arbitrator in a binding 
arbitration proceeding finds any provision of this Agreement, or the 
application thereof, to be unenforceable, then the remaining provisions of 
this Agreement will be interpreted so as best to reasonably effect the intent 
of the parties.  The parties further agree that the court or arbitrator shall 
replace any such invalid or unenforceable provisions with valid and 
enforceable provisions designed to achieve, to the extent possible, the 
business purposes and intent of such unenforceable provisions.

          (g)  COUNTERPARTS.  This Agreement may be executed in counterparts, 
each of which will be an original as regards any party whose signature 
appears thereon and all of which together will constitute one and the same 
instrument. This Agreement will become binding when one or more counterparts 
hereof, individually or taken together, bear the signatures of both parties 
reflected hereon as signatories.

          (h)  DISPUTE RESOLUTION.

               (i)    ARBITRATION OF DISPUTES.  Any dispute under this 
Agreement shall be resolved by arbitration in Dallas, Texas and, except as 
herein specifically stated, in accordance with the commercial arbitration 
rules of the American Arbitration Association ("AAA RULES") then in effect, 
except that depositions and documentary discovery shall be freely permitted.  
However, in all events, these arbitration provisions shall govern over any 
conflicting rules that may now or hereafter be contained in the AAA Rules.  
Any judgment upon the award rendered by the arbitrator may be entered in any 
court having jurisdiction over the subject matter thereof.  The arbitrator 
shall have the authority to grant any equitable and legal remedies that would 
be available in any judicial proceeding instituted to resolve such dispute, 
and may, in his or her discretion, award attorneys' fees, expenses and costs.

               (ii)   COMPENSATION OF ARBITRATOR.  Any such arbitration will 
be conducted before a single arbitrator who will be compensated for his or 
her services at a rate to be 

EMPLOYMENT AGREEMENT - Page 6
<PAGE>

determined by the parties or by the American Arbitration Association, but 
based upon reasonable hourly or daily consulting rates for the arbitrator if 
the parties are not able to agree upon his or her rate of compensation.

               (iii)  SELECTION OF ARBITRATOR.  The American Arbitration 
Association will have the authority to select an arbitrator from a list of 
arbitrators who are lawyers familiar with Texas contract law; PROVIDED, 
HOWEVER, that such lawyers cannot work for a firm then performing services 
for either party, that each party will have the opportunity to make such 
reasonable objection to any of the arbitrators listed as such party may wish 
and that the American Arbitration Association will select the arbitrator from 
the list of arbitrators as to whom neither party makes any such objection.  
If the foregoing procedure is not followed, then each party will choose one 
person from the list of arbitrators provided by the American Arbitration 
Association (provided that such person does not have a conflict of interest), 
and the two persons so selected will select from the list provided by the 
American Arbitration Association the person who will act as the arbitrator.

               (iv)   PAYMENT OF COSTS.  Subject to the last sentence of 
Section 10(h)(i) above, the Company and Mr. Brown will each pay 50% of the 
initial compensation to be paid to the arbitrator in any such arbitration and 
50% of the costs of transcripts and other normal and regular expenses of the 
arbitration proceedings.

               (v)    BURDEN OF PROOF.  For any dispute submitted to 
arbitration, the burden of proof will be as it would be if the claim were 
litigated in a Texas judicial proceeding.

               (vi)   AWARD.  Upon the conclusion of any arbitration 
proceedings hereunder, the arbitrator will render findings of fact and 
conclusions of law and a written opinion setting forth the basis and reasons 
for any decision reached and will deliver such documents to each party to 
this Agreement along with a signed copy of the award.

               (vii)  TERMS OF ARBITRATION.  The arbitrator chosen in 
accordance with these provisions will not have the power to alter, amend or 
otherwise affect the terms of these arbitration provisions or the provisions 
of this Agreement.

               (viii) NATURE OF REMEDY.  Except as specifically otherwise 
provided below, arbitration will be the sole and exclusive remedy of the 
parties for any dispute arising out of this Agreement.

               (ix)   EQUITABLE REMEDY.  Notwithstanding the provisions of 
this Section 10(h) and the arbitration provided for herein, actions initiated 
or maintained by the parties for injunctive or similar equitable relief are 
not subject to arbitration, and may be brought by the parties in any court 
that has jurisdiction, and, should the party bringing any such action 
prevail, all costs and expenses (including legal fees) shall be borne by the 
party against whom such action was brought.

reporting requests made by the Board of Directors or the Management Committee 
of PSN.

               (c)  JDCA may submit proposals for its services to be remarketed
through PSN to PSN's Board of Directors or Management Committee and shall
abstain from voting with respect to such proposals.

               (d)  JDCA shall hire one or more full-time employee(s) fully
dedicated to PSN when, in JDCA's sole reasonable judgment, such employee(s)
become appropriate or necessary in order to conduct the operations of PSN.

               (e)  JDCA shall place appropriate emphasis on cash management
within PSN to minimize the need for additional working capital.

               (f)  Each year JDCA shall prepare an annual business plan and
operating budget ("Business Plan") to be approved by the Board of Directors of
PSN.  JDCA shall prepare quarterly operating budgets for PSN for the first year
of the term of this Agreement, which shall be consistent with the Business Plan,
to be approved by the Board of Directors of PSN.  After the first year of the
term of this Agreement, the timing and frequency of budget reporting by JDCA
will be determined jointly by JDCA and PSN's Management Committee.  Modification
of the Business Plan and/or operating budgets may be made quarterly if approved
by the Board of Directors or Management Committee of PSN, as appropriate.

               (g)  JDCA shall use its reasonable best efforts to conform with
the budgeted expense levels approved by the Board of Directors of PSN.  If a
significant negative variance between actual and budgeted net profits occurs,
JDCA will develop a revenue enhancement and/or expense reduction and
implementation plan and submit such plan to Management Committee of PSN for its
review and approval.

          COMPENSATION.  For the services to be rendered and the facilities to
be furnished by JDCA, as provided for in this agreement, JHDCA shall be
compensated by PSN in accordance with the following terms:
          
               (a)  PSN shall pay to JDCA each month a Management Fee equal to
JDCA's Fully Loaded Transfer Cost plus 20% of PSN's total direct operating
expenses ("PSN Operating Expenses") for that month.  PSN shall also pay to JDCA
an Incentive Fee for 


                                       4

<PAGE>

each fiscal year in which 25% of PSN's pre-tax, pre-Management Fee net profits
for that year exceeds 20% of PSN Operating Expenses for such year.  The
Incentive Fee shall be payable as soon as reasonably possible following the end
of each fiscal year and shall be equal to the amount by which 25% of PSN's 
pre-tax net profits for the year exceeds 20% of PSN Operating Expenses for 
such year, provided that the Incentive Fee shall not exceed up to 40% of 
total PSN Operating Expenses.  "Fully Loaded Transfer Cost" shall include the 
actual hourly compensation cost of any employee who performs services for 
PSN, grossed up by a calculated percentage to reimburse JDCA for the various 
direct and overhead expenses attributable to the general day-to-day business 
operations of JDCA ("JDCA Expenses").  The Fully Loaded Transfer Cost shall 
be calculated as illustrated in Exhibit B to this Agreement and JDCA's 
calculation of the Fully Loaded Transfer Cost shall be subject to the 
performance of certain agreed-upon audit procedures performed annually by an 
independent public accountant.  JDCA's Fully Loaded Transfer Cost shall 
include:  administrative department salaries; all employee-related benefits 
and taxes; office rent; general office supplies; telephone; secretarial; 
human resource department-related; general insurance; general computer; 
furniture and equipment depreciation in the conduct of PSN's business.  JDCA 
Expenses and Transfer Cost methodology shall be calculated in accordance with 
industry standards and Generally Accepted Accounting Principles. If a 
significant event or change in circumstances causes such expenses to 
materially exceed industry standards, JDCA and PSN may agree to readjust the 
calculation of the Fully Loaded Transfer Cost or any JDCA Expense.  The 
percentage of JDCA Expense includable in calculating the Fully Loaded 
Transfer Cost shall be determined on a fiscal year quarterly basis one 
quarter in arrears.  PSN Operating Expenses shall be accounted for separately 
and shall consist of the operating expenses set forth on Exhibit C to this 
Agreement, including, but not limited to, expenses of PSN relating to:  sales 
travel; commissions; contract negotiation and legal fees; JDCA's services 
pursuant to this Agreement; salaries; PSN's overhead expenses and staff 
bonuses; interest on borrowed money; taxes and fees payable to Federal state 
and other governmental agencies; outside auditing expenses; and other 
expenses not specified which are properly payable by PSN.

               (b)  PSN shall reimburse JDCA on a monthly basis for any PSN
Operating Expenses paid by JDCA and/or its employees.  A policy shall be
developed jointly by PSN and JDCA to establish guidelines for the reimbursement
of PSN Operating Expenses paid by JDCA and/or its employees.  Such policy shall
generally provide for reimbursement of:  reasonable air and ground
transportation, including tolls, parking, taxi, bus or auto rental; expenses for
lodging and meals (provided, however, that personal expenses charged against a
hotel room or separately will not be reimbursed); reasonable valet and laundry
charges for 


                                       5

<PAGE>

trips of more than three (3) days duration; necessary business calls; and
reasonable tipping.

               (c)  JDCA shall submit to PSN a monthly invoice during the first
week of each month which shall be in the format generally set forth in Exhibit D
to this Agreement.  PSN shall pay the invoiced amount within thirty (30) days of
the invoice date.  All past due amounts shall accrue interest at the prime rate
plus one percent (1%) divided by twelve per each thirty (30) days past due.

               (d)  JDCA will from time to time employ or associate with itself
such person or persons as JDCA may believe to be particularly suited to assist
it in performing services under this Agreement.  Such person or persons may be
officers and employees who are employed by both JDCA and PSN.

     6.   LIMITATION OF LIABILITIES; INDEMNIFICATION.

          (a)  JDCA shall not be liable for any error of judgment or mistake of
law or for any loss suffered by PSN in connection with the performance of JDCA's
obligations and duties under this Agreement, except a loss resulting from JDCA's
willful misconduct, bad faith or gross negligence in the performance of such
obligations and duties, or by reason of its reckless disregard thereof.  Any
person, even though also an officer, director, partner, employee or agent of
JDCA, shall be deemed, when rendering services to PSN or acting on any business
of PSN (other than services or business in connection with JDCA's duties
hereunder), to be acting solely for PSN and not as an officer, director,
partner, employee or agent or one under the control or discretion of JDCA even
though paid by JDCA.  JDCA shall not be liable for any action taken or omitted
in good faith at the request or direction of the Board of Directors of PSN or
any committee thereof in connection with the performance of JDCA's duties under
this Agreement.  JDCA also shall not be liable for actions taken or omitted in
good faith in reliance on advice received from its or PSN's legal counsel,
independent public accountants or other professional advisors.  JDCA shall not
be liable for any special or consequential damages arising in connection with
the performance of JDCA's obligations and duties under this Agreement.

          (b)  Notwithstanding any other provision of this Agreement, JDCA shall
not be liable for any loss suffered by PSN in connection with the performance of
JDCA's obligations and duties under this Agreement unless PSN has initiated a
legal or arbitration proceeding with respect to such loss within three (3) years
of the occurrence of the event, action or failure to act giving rise to such
loss.

          (c)  Any dispute or controversy arising between JDCA and PSN in
connection with the interpretation of this Agreement shall be settled
exclusively by binding arbitration in Dallas, Texas in


                                       6

<PAGE>

accordance with the rules of the American Arbitration Association then in effect
and judgment upon the award rendered may be entered in any court having
jurisdiction thereof.

          (d)  PSN will indemnify JDCA against and hold it harmless from any and
all losses, claims, damages, liabilities or expenses (including counsel fees and
expenses) resulting from any claim, demand, action or suit relating to the
operation of PSN, unless (i) such loss, claim, damage, liability or expense
results from the willful misconduct, bad faith or gross negligence of JDCA in
the performance of such obligations and duties or by reason of its reckless
disregard thereof and (ii) a legal or arbitration proceeding has been initiated
within three (3) years of the occurrence of the event, action or failure to act
giving rise to such loss, claim, damage, liability or expense.  JDCA shall
promptly notify PSN in writing of: the assertion against JDCA of any claim or
potential liability with respect to which indemnity may be sought hereunder; the
discovery of any such potential liability; or the commencement of any action or
proceeding with respect to which indemnity may be sought hereunder; PROVIDED,
that the failure promptly to give such notice shall not affect JDCA's rights
hereunder except to the extent that such failure shall actually materially and
adversely affect PSN or its rights hereunder.  JDCA shall not confess,
compromise or settle any claim indemnifiable hereunder without the prior written
consent of PSN.  PSN shall have the right to control the defense against any
claim or liability indemnifiable hereunder if (i) PSN notifies JDCA, within
thirty (30) days after receiving written notice from JDCA of an indemnifiable
claim or liability, that PSN intends to defend against such claim or liability,
or, if required in a shorter time than thirty (30) calendar days, PSN makes the
requisite response to such claim or liability asserted and (ii) PSN diligently
pursues the defense against such claim or liability.

     7.   TERM; RENEWAL/TERMINATION.

          (a)  This Agreement shall become effective on November 18, 1993 and
shall remain in full force and effect for a term of five (5) years from the
effective date unless terminated early pursuant to the provisions of subsection
(c) of this Section 7.

          (b)  Prior to the end of the four (4) years from the effective date of
this Agreement, JDCA and PSN will convene negotiations in good faith to extend
or modify this Agreement unless this Agreement has been terminated early
pursuant to the provisions of subsection (c) of this Section 7.  If such
negotiations do not conclude within six (6) months of the expiration of the term
of this Agreement, JDCA and PSN may agree to extend this Agreement on a 
month-to-month basis until negotiations reach a conclusion.


                                       7

<PAGE>

          (c)  This Agreement is subject to early termination (i) upon the
mutual agreement of the parties; (ii) by PSN with thirty (30 days' prior written
notice upon the commission of willful misconduct, gross negligence or fraud by
JDCA; (iii) by PSN with thirty (30) days' prior written notice upon JDCA's
failure to begin to implement within 60 calendar days agreed-upon expense
reduction initiatives as provided at subsection (e) of Section 4 of this
Agreement; or (iv) pursuant to Section 8 hereof.  The terms and provisions of
Sections 6, 10 and 11 shall survive any such early termination of this
Agreement.

          (d)  In the event of any termination pursuant to this Section 7, JDCA
shall be entitled to a pro rata portion of (i) the Management Fee otherwise
payable at the end of the month during which such termination occurs and (ii)
the Incentive Fee, if any, otherwise payable at the end of the fiscal year
during which such termination occurs; provided, however, that the determination
of whether any Incentive Fee is payable, and the calculation of the amount of
the Incentive Fee, shall be based upon the amount of PSN's pre-tax net profits
and PSN Operating Expenses for the portion of the fiscal year before termination
occurred.  Upon any termination, each party shall deliver to the other party all
property, documents, books and records, including related software, of the other
party then in its custody or possession.  JDCA shall cooperate with PSN and any
successor provider of management services selected by PSN in the orderly
transfer and assumption of the management responsibilities of PSN.

          (e)  Upon any termination pursuant to Section 7(c) or in the event
this Agreement terminates upon the expiration of its initial five (5) year term
as provided in Section 7(a), JDCA shall have the right to require PSN to
purchase from JDCA up to seventy-five percent (75%) of the securities of PSN
help by JDCA, except as provided in the third sentence of this subsection.  JDCA
shall notify PSN of JDCA's decision to seek such a purchase by PSN within sixty
(60) days of the effective date of such termination.  To the extent that any
securities sought to be sold by JDCA to PSN hereunder would require one or more
holders of securities of PSN ("Stockholders") to obtain the prior approval of
the Federal Reserve Board under Section 4 of the Bank Holding Company Act and
such Stockholder(s) is unable after using its best efforts to obtain, or is in
good faith unwilling to seek, such Federal Reserve Board approval, JDCA will not
have the right to require PSN to purchase such securities and JDCA and the Board
of Directors of PSN will in good faith negotiate to provide JDCA with an
economic result substantially comparable to the purchase by PSN of such
securities.  To the extent that PSN is required hereunder to purchase securities
held by JDCA, PSN shall be required to consummate such purchase within 120 days
of such notice.  Unless otherwise agreed to by JDCA and PSN within ten (10) days
of the provision of notice by JDCA, the purchase price to be paid by PSN for
such securities shall be the value of the securities as determined by a mutually
acceptable nationally 


                                       8

<PAGE>

recognized investment banking or accounting firm.  If the parties shall fail to
agree on the selection of an investment banking or accounting firm, then each
shall select one such firm (and each shall pay any fees charged by the firm it
selects) and such firms shall agree to, as promptly as practicable thereafter, a
nationally recognized investment banking or accounting firm to determine the
value of the securities.  PSN and JDCA shall each pay one-half of the expenses
of the investment banking or accounting firm making the determination as to such
value.  PSN may pay the purchase price in a lump sum or in equal annual
installments over five (5) years.  All determinations made pursuant to this
subsection shall be final, conclusive and binding on the parties.

          (f)  JDCA and PSN agree that Section 7(e) of this Agreement supersedes
the rights and obligations of JDCA and PSN as between each other pursuant to
Section 5.4 of the Payment Systems Network Inc. Stockholders' Agreement dated
November 18, 1993 (Stockholders' Agreement) and that the understanding of the
parties with respect to the subject matter of Section 7(e) of this Agreement
shall be interpreted without regard to any inconsistent provision contained in
Section 5.4 of the Stockholders' Agreement.

     8.   DEFAULT, BANKRUPTCY, ETC. OF EITHER PARTY.  For the purposes of
Section 7 hereof, either party to this Agreement defaults if such party:

          (a)  materially breaches any material provision of this Agreement and,
after notice of such breach, shall have failed to cure such breach within thirty
(30) days after notice of such breach is given to the breaching party; or

          (b)  has a petition filed against it for an involuntary proceeding
under any applicable bankruptcy, insolvency or other similar law now or
hereafter in effect, and such petition shall not have been dismissed within
sixty (60) days of filing; or a court having jurisdiction shall have appointed a
receiver, liquidator, assignee, custodian, trustee, sequestrator or similar
official of such party for any substantial portion of its property, or ordered
the winding up or liquidation of its affairs; or

               (c)  commences a voluntary proceeding under any applicable
bankruptcy, insolvency or other similar law now or hereafter in effect, or shall
have made any general assignment for the benefit of creditors, or shall have
failed generally to pay its debts as they became due.


                                       9

<PAGE>

The defaulting party agrees that, if any of the events specified in subsections
(b) or (c) of this Section 8 shall occur, it shall give written notice thereof
to the other party within seven (7) days following occurrence of such event. 
Upon receipt of such notice, or upon becoming aware of a default the other party
may, in its sole discretion, terminate this Agreement immediately upon delivery
of a written notice of such termination to the defaulting party.

     9.   AMENDMENTS.  No provision of this Agreement may be changed, discharged
or terminated orally, but only by an instrument in writing signed by the party
against which enforcement of the change, discharge or termination is sought.

     10.  CONFIDENTIALITY.  All books, records, information and data pertaining
to the business of PSN and PSN's prior, present or potential shareholders and
customers that are exchanged or received pursuant to the performance of JDCA's
duties under this Agreement shall remain confidential and shall not be disclosed
to any other person, except as specifically authorized by PSN or as may be
required by law.

     11.  PROPERTY RIGHTS.  JDCA and PSN agree that all systems; designs;
programming materials; flowcharts; computer programs; techniques, inventions or
discoveries developed in the context of JDCA's services for PSN pursuant to this
Agreement; and other materials developed or originated by JDCA for PSN pursuant
to this Agreement ("Work Product"), shall be the property of, and are hereby
assigned to, PSN.  JDCA and PSN further agree that nothing in this Agreement
shall be deemed to preclude JDCA or PSN from using any ideas, know how or other
information or knowledge ("Ideas") utilized by JDCA in developing the Work
Product, subject to the restrictions of Section 12 of this Agreement.  Any Ideas
generated by JDCA other than in the course of performing services for PSN under
this Agreement shall be the exclusive property of JDCA and any Ideas generated
by PSN employees not employed by JDCA shall be the exclusive property of PSN.

     12.  OTHER BUSINESS AND ACTIVITIES OF JDCA.  Except to the extent necessary
to perform JDCA's obligations under this Agreement, nothing herein shall be
deemed to limit or restrict the right of JDCA or any employee of JDCA to engage
in any other business or to devote time and attention to the management or other
aspects of any other business, whether of a similar or dissimilar nature, or to
render services of any kind to any other corporation, firm, individual or
association; provided, however, that during the term of this Agreement, JDCA
agrees not to engage in any activities which are functionally competitive with
the electronic check presentment and related services to be provided by PSN. 
PSN acknowledges that, except as provided in subsection (d) of Section 4 of this
Agreement, the persons employed by JDCA to assist in the performance of JDCA's
duties under this Agreement are not required to devote their full time to such 


                                      10

service and nothing contained in this Agreement shall be construed to the
contrary.

     13.  NEGATION OF PARTNERSHIP OR JOINT VENTURE.  Nothing contained in this
Agreement shall constitute, or be construed to be or to create, a partnership,
joint venture or lease between JDCA and PSN.

     14.  MISCELLANEOUS.

Agreement to be given in writing to PSN or JDCA shall be sufficiently given if

               to renew this Agreement, in which event this

<PAGE>

               Agreement will terminate at the end of its then current term, 
               (ii) at the time of renewal JDCA is not competitive in either 
               price or quality with respect to the provision of the services, 
               in which event (if JDCA, after being given a reasonable 
               opportunity to demonstrate that it is competitive in price and 
               quality, fails to do so), PSN may, terminate this Agreement on 
               one hundred eighty (180) days prior notice to JDCA or (iii) the 
               PSN Board of Directors determines that it is in the best interest
               of PSN to hire employees for PSN to perform such services.  For 
               the purposes of the preceding sentence, differences in price 
               shall be considered only with respect to services of 
               substantially similar nature and quality.

          (c)  Paragraphs (e) and (f) shall be deleted in their entirety.

     IN WITNESS WHEREOF, the parties hereto have duly executed this First
Amendment as of the day and year first above written.

                    Expenses to be reimbursed and current month Management
                    Fees will coincide.

                    approved by the Board of Managers shall remain in

                    available.

               investment requirements to the Functional Members for
               both individual and collective development
               opportunities.  If, upon formal presentation of the
               proposed investment required, the INFITEQ Functional
               Member(s) decline(s) to invest or, within 30 days, have
               not stated an intention to participate, then Carreker
               can seek outside capital investment, subject to
               approval by the Board of Managers.  Such investors will
               have full claim on any incremental profits generated
               from the integrated capabilities in accordance with the
               INFITEQ Revenue Flow Model set forth in EXHIBIT D(ii)

                    hereto, (iii) any negligent acts or omissions or
                    willful misconduct by or on behalf of INFITEQ in the
                    course of fulfilling the obligations of INFITEQ
                    hereunder, (iv) subject to the terms of this Agreement,
                    any and all payments made by Carreker to third parties
                    on behalf of INFITEQ, and (v) all reasonable fees and
                    expenses incurred in the enforcement of this indemnity
                    by Carreker; provided that INFITEQ shall not be
                    required to indemnify Carreker for any losses to the
                    extent that they are caused by the willful misconduct,
                    bad faith, or gross negligence of Carreker in
                    connection with the performance of its services under
                    this Agreement.  Carreker shall not be liable for any
                    action taken or omitted in good faith at the request or
                    direction of the Board of Managers of INFITEQ or any
                    committee thereof in connection with the performance of
                    Carreker's duties under this Agreement.  Carreker shall
                    also not be liable for actions taken or omitted in good
                    faith in reliance on advice received from its or
                    INFITEQ's legal counsel, independent public accountants
                    or other professional advisors.
     
               (b)  Carreker shall indemnify, defend and hold INFITEQ
                    harmless from and against any losses arising out of or
                    relating to (1) any default, breach, violation or non-
                    performance by Carreker of any covenant, obligation,
                    condition or agreement of Carreker contained in this
                    Agreement, (ii) any breach of the representations and
                    warranties of Carreker contained in this Agreement, or
                    in any document, undertaking or certificate required by
                    Carreker pursuant hereto, (iii) any negligent acts or
                    omissions or willful misconduct by or on behalf of
                    Carreker in the course of fulfilling the obligations of
                    Carreker hereunder, and (iv) all reasonable fees and
                    expenses incurred in the enforcement of this indemnity
                    by INFITEQ, provided that Carreker shall not be
                    required to indemnify INFITEQ for any losses to the
                    extent that they are caused by the willful misconduct,
                    bad faith or gross negligence of INFITEQ.
     
               (c)  Each party's indemnification rights shall be their sole
                    remedy with respect to a party's losses resulting from
                    third party liabilities.  Each party's right to damages
                    shall be limited to compensatory damages, and no party
                    to this Agreement shall be liable for any indirect,
                    special, punitive or consequential damages.
     
               (d)  Notwithstanding any other provisions of this Agreement,
                    Carreker shall not be liable for any loss suffered by
                    INFITEQ in connection with the performance of
                    Carreker's obligations and duties under this Agreement
                    unless INFITEQ has initiated a legal or arbitration
                    proceeding with respect to such loss within three (3)
                    years of the occurrence of the event, action or failure
                    to act giving rise to such loss.

               (e)  Any dispute or controversy arising between Carreker and
                    INFITEQ in connection with the interpretation or
                    enforcement of this Agreement shall be settled
                    exclusively by binding arbitration in Dallas, Texas in
                    accordance with the rules of the American Arbitration
                    Association then in effect and judgment upon the award
                    rendered may be entered in any court having
                    jurisdiction thereof.

          9.   TERM, RENEWAL.  Subject to earlier termination as provided in
               this Agreement, this Agreement shall become effective on the 
               date herein and shall remain in force and effect for a term of
               ten (10) years, and shall automatically renew thereafter for 
               successive two (2) year periods, subject to termination by 
               either party at the end of the original term or any extension 
               thereof by the giving of written notice of nonrenewal at least
               120 days prior to the end of the original term or the extension
               thereof, as applicable.
     
          10.  TERMINATION FOR CONVENIENCE.

               (a)  During the Ramp-up Phase, INFITEQ shall not be able to
                    terminate this Agreement except for cause as provided
                    in Section 11.
     
               (b)  After the Ramp-up Phase, either party may terminate
                    this Agreement, with or without cause, upon not less
                    than 180 days prior written notice to the other party. 
                    In no event shall INFITEQ terminate this Agreement for
                    convenience prior to one year after the effective date
                    of formation, as defined in the Limited Liability
                    Company Operating Agreement.
     
               (c)  In the event of any termination of INFITEQ pursuant to
                    this Section 10, in addition to all other amounts owing
                    to Carreker through the date of termination as provided
                    herein, Carreker shall be entitled to reimbursement for
                    any reasonable and documented expenses actually incurred
                    in connection with a mutually agreed upon unwind period.
                    Carreker shall use its commercially reasonable efforts to
                    mitigate all reasonable and documented expenses.  Carreker
                    shall additionally be entitled to continue to receive any
                    management services revenue in accordance with the Revenue
                    Flow Model as described in Exhibit D(ii), for any Customer 
                    Contracts as long as those Customer Contracts are in effect.
                    The provisions set forth in this paragraph apply to all 
                    parts of Section 10 and a termination pursuant to 
                    Section 11(e).

               (d)  In the event of termination by Carreker pursuant to this 
                    Section 10, INFITEQ shall be entitled to reimbursement for
                    any reasonable and documented expenses actually incurred in
                    connection with a mutually agreed upon unwind period.  
                    INFITEQ shall use its commercially reasonable efforts to 
                    mitigate, and permits Carreker as INFITEQ's agent to 
                    mitigate, all reasonable and documented expenses.

               (e)  Upon any termination hereunder, each party shall deliver to
                    the other party all property, documents, books and records,
                    including related software, of the other party then in its 
                    custody or possession.  Carreker shall cooperate with 
                    INFITEQ and any successor provider of management services 
                    selected by INFITEQ in the orderly transfer and assumption
                    of the management responsibilities of INFITEQ.

               (f)  Except as provided in the Limited Liability Company 
                    Operating Agreement of INFITEQ, the rights and obligations
                    of Carreker as a Functional Member of INFITEQ shall not be
                    affected by the termination of this Agreement.

               (g)  Carreker agrees that subsequent to the expiration of this 
                    Agreement, Carreker shall provide, for a reasonable period
                    of time, but not to exceed six (6) months without being 
                    subjected to additional premium, such management services
                    as are reasonably requested by INFITEQ, at a fee to be 
                    mutually agreed upon by INFITEQ and Carreker.

               (h)  In the event of the acquisition of substantially all
                    other assets or voting securities of INFITEQ by another
                    entity, this Agreement shall remain in full force and
                    effect.

          11.  TERMINATION FOR CAUSE.  Either party may terminate this Agreement
               for cause if the other party:

               (a)  materially breaches any material provision of this
                    Agreement and, after notice of such breach, shall have
                    failed to cure such breach within thirty (30) days after 
                    notice of such breach is given to the breaching party; or

               (b)  commits an act of willful misconduct, gross negligence or 
                    fraud.  Such termination may be effected by giving the other
                    party written notice of termination, which notice shall 
                    specifically identify the act upon which termination is 
                    based; or

               (c)  has a petition filed against it for an involuntary
                    proceeding under any applicable bankruptcy, insolvency or 
                    other similar law now or hereafter in effect, and such 
                    petition shall not have been dismissed within sixty (670)
                    days of filing; or a court having jurisdiction shall have
                    appointed a receiver, liquidator, assignee, custodian, 
                    trustee, sequestrator or similar official of such party for
                    any substantial portion of its property, or ordered the 
                    winding up or liquidation of its affairs; or

               (d)  commences a voluntary proceeding under any applicable
                    bankruptcy, insolvency or other similar law now or
                    hereafter in effect, or shall have made any general
                    assignment for the benefit of creditors, or shall have

<PAGE>

                    failed generally to pay its debts as they became due. 
                    The defaulting party agrees that, if any of the events
                    specified in subsections (b) or (c) of this Section 11
                    shall occur, it shall give written notice thereof to the 
                    other party within seven (7) days following occurrence of
                    such event.  Upon receipt of such notice, or upon becoming
                    aware of a default the other party may, in its sole 
                    discretion, terminate this Agreement immediately upon 
                    deliver of a written notice of such termination to the 
                    defaulting party; or

               (e)  in the case of Carreker, in the event of a merger or
                    acquisition by a entity resulting in a change of control 
                    in Carreker (a change of control shall occur if the merger
                    or acquisition results in a significant change of the 
                    current management structure and in the acquiring entity 
                    owning 51% or more of the total stock of Carreker); Carreker
                    shall use its best efforts to notify the Board prior to any
                    such change of control; the Board shall then have not more 
                    than 15 days from the date of notification to decide whether
                    to terminate this Agreement pursuant this clause (e); 
                    provided, however, that a termination pursuant to this 
                    clause shall require the affirmative vote of at lest 
                    two-thirds of the Board of Managers; and provided, further,
                    Carreker becoming a publicly held company will not be
                    considered a change of control; or

               (f)  in the event this Agreement is terminated by INFITEQ
                    pursuant to this Section 11, Carreker shall be entitled
                    to costs for services expended through the effective
                    date of such termination.  Termination of Carreker
                    Management Services shall be separate and apart from
                    the Customer Contracts and associated revenues Carreker
                    has as a Functional Member.
     
          12.  AMENDMENTS.  No provision of this Agreement may be changed,
               discharged or terminated orally, but only by an instrument in 
               writing signed by the party against which enforcement of the 
               change discharge or termination is sought.

          13.  CONFIDENTIALITY.  All books, records, information and data
               pertaining to the business of INFITEQ and INFITEQ's prior, 
               present or potential shareholders and customers that are 
               exchanged or received pursuant to the performance of Carreker's
               duties under this Agreement shall remain confidential and shall
               not be disclosed to any other person, except as specifically 
               authorized by INFITEQ or as may be required by law.

          14.  OTHER BUSINESS AND ACTIVITIES OF CARREKER.  Except to the extent
               necessary to perform Carreker's obligations under this Agreement,
               nothing herein shall be deemed to limit or restrict the right of
               Carreker or any employee of Carreker to engage in any other 
               business or to devote time and attention to the management or 
               other aspects of any other business, whether of a similar or
               dissimilar nature, or to render services of any kind to any 
               other corporation, firm, individual or association; provided, 
               however, that during the term of this Agreement, Carreker agrees
               not to engage in any activities which are functionally 
               competitive with the


                                      10

<PAGE>

               services to be provided by INFITEQ.  INFITEQ acknowledges that 
               the persons employed by Carreker to assist in the performance 
               of Carreker's duties under this Agreement are not required to 
               devote their full time to such service and nothing contained in 
               this Agreement shall be construed to the contrary.

          15.  NEGATION OF MEMBERSHIP OR JOINT VENTURE.  Nothing contained in
               this Agreement shall constitute, or be construed to be or to 
               create, a partnership, joint venture or lease between Carreker 
               and INFITEQ.

          16.  MISCELLANEOUS.

               (a)  Any notice or other instrument authorized or required
                    by this Agreement to be given in writing to INFITEQ or
                    Carreker shall be sufficiently given if addressed to be
                    that party and received by it at its office set forth
                    below or at such other place as it may from time to
                    time designate in writing.

               (b)  This Agreement shall extend to and shall be binding
                    upon the parties hereto and their respective successors
                    and permitted assigns; PROVIDED, HOWEVER, that this
                    Agreement shall not be assignable without the written

                    have the absolute right to assign this Agreement to a
                    subsidiary or affiliate.  In the event that Carreker
                    assigns this Agreement to an affiliate or subsidiary,
                    there shall be no unaffiliated third-party owner in
                    such entity without the written consent of the Board of

                    constitute only one instrument.

               (e)  The captions of this Agreement are included for

               (f)  Sections 8, 10(c), 10(e), 10(g), 11(f), 13, and 16 shall

NOTES:

- -    DISCOUNTED PROVIDER PRICING is defined as less than acceptable minimum 
     Provider margins (e.g. 10%) for services in a given Customer Contract.

- -    "OFF-THE-SHELF" Customer Contracts, as illustrated in Exhibit B(ii), are 
     defined as single Provider Customer Contracts where mark-up opportunities 
     are considered minimal.

- -    INTEGRATED Customer Contracts, as illustrated in Exhibit B(ii), are defined
     as multi-Provider Customer Contracts where Carreker has bundled services 
     from two or more Providers of INFITEQ including additional tangible 
     services and/or software, consulting, or training services to be provided 
     to a Customer or Client Bank.  Integrated Customer Contracts will require 
     more Carreker management Services, and thus entail higher management
     compensation rates.

Exhibit B(i)

- -    Providers will contribute the percent of revenue stated above only to the 
     extent that INFITEQ mark-up over cost of service from the Provider does not
     meet the agreed upon rate of compensation.

     will support INFITEQ service offerings.  The Service Warehouse will be 
     funded out of additional capital raised from Sponsor Members and new 
     Functional Members that elect to participate in its funding.

                           STRATEGIC ALLIANCE AGREEMENT

     THIS STRATEGIC ALLIANCE AGREEMENT ("AGREEMENT"), is made effective as of 
October 1996, by and between SCIENCE APPLICATIONS INTERNATIONAL CORPORATION, 
a Delaware corporation ("SAIC"), and THE CARREKER GROUP, INC., a Texas 
corporation ("CARREKER"), who agree as follows:
     1.   RECITALS.  This Agreement is entered into in contemplation of the
following facts and circumstances:

          1.1    OBJECTIVES.  Carreker and SAIC desire to establish an
     arrangement whereby they can in the future jointly offer such services,
     products and technology as they may possess to prospective users of the
     services, products and/or technology the parties may offer with particular
     emphasis on commercial financial institutions and federal government
     agencies ("CUSTOMERS") pursuant to terms, conditions and prices mutually
     agreed upon by the parties in advance of entering any contract with a
     Customer.  The parties also anticipate that each may identify opportunities
     which they do not pursue jointly, but with respect to which the services,
     products and/or technology of the other party may be marketed and sold to a
     Customer.  This Agreement pertains only to the SAIC Financial Services
     Practice within SAIC's Technology Solutions Sector (the "SAIC FINANCIAL
     SERVICES PRACTICE").

          1.2    PURPOSE.  This Agreement (a) sets forth (i) the provisions and
     conditions pursuant to which either party may identify and advise the other
     party of a mutually beneficial business opportunity and (ii) the
     circumstances under which parties may pursue the opportunity jointly, and
     (b) establishes the basis of payments to a party that introduces an
     opportunity which is not pursued jointly but with respect to which the
     other party successfully markets and sells its services, products and/or
     technology.

     2.   SCOPE OF AGREEMENT.  The parties specifically acknowledge and agree
that this Agreement shall not apply to any work or contracts that commenced
prior to the date of this Agreement, unless the parties otherwise agree in
writing.  This Agreement is not an exclusive dealings agreement and each party
is free to do business with others with respect to Customers or otherwise;
PROVIDED, HOWEVER, during the first three (3) years of this Agreement, Carreker
shall provide SAIC with a preferential opportunity to provide services, products
and/or technology to each prospective Customer that Carreker solicits in those
instances where it appears to Carreker that a teaming relationship is necessary
and that SAIC could provide the services, products and/or technology that is the
subject matter of the solicitation.

     3.   MUTUAL BUSINESS OPPORTUNITIES.

          3.1    REPRESENTATIVES.  Each party shall designate one or more
     authorized representatives to interact with the other for purposes hereof
     ("REPRESENTATIVE") until such time as either party notifies the other of
     its decision to designate a new Representative.

<PAGE>

          3.2    REVIEW OF OPPORTUNITIES.  The parties' Representatives may
     select and submit to the other for its consideration such business
     opportunities identified by a party that the party believes may be of
     mutual interest and the Representatives shall jointly determine whether to
     pursue such business opportunity together.  If the parties determine to
     pursue an opportunity jointly, they also shall determine the terms,
     conditions and prices that will be offered to the prospective Customer and
     the strategy by which the parties will attempt to acquire the business
     (including, without limitation, designation of the party which shall serve
     as the prime contractor, the party which will perform the necessary
     services and provide the appropriate products and/or technology, and the
     party which will assume responsibility for presentation of the parties'
     proposal).  The Representatives shall meet and confer, either in person or
     by teleconference, at least once monthly, to discuss prospective business
     opportunities and performance with respect to existing accounts.

          3.3    COOPERATION.  If the parties pursue a business opportunity
     jointly, each party shall utilize commercially reasonable efforts to market
     and obtain the targeted business; PROVIDED, HOWEVER, that the parties shall
     coordinate their activities so as to provide a unified presentation to the
     prospective Customer.

     4.   TRANSACTIONS.

          4.1    JOINT TRANSACTIONS.  Whenever a mutually satisfactory contract
     to perform or provide services, products and/or technology to a Customer
     has been obtained due to the active and substantial marketing and sales
     efforts of both parties, Carreker will have the right to provide services,
     products and/or technology having a value up to fifty percent (50%) of the
     estimated value of the contract and Carreker shall be entitled to its
     proportion of the revenue derived from the services, products and/or
     technology provided by Carreker.  SAIC shall provide or obtain all
     services, products and/or technology not provided by Carreker and shall
     receive the revenue represented by the proportion of the revenue derived
     from the services, products and/or technology provided by SAIC.

          4.2    SOLE EFFORTS TRANSACTIONS.  Whenever a mutually satisfactory
     contract to provide services, products and/or technology to a Customer has
     been obtained by the sole marketing and sales efforts of such party, the
     contracting party shall make a commercially reasonable good faith effort to
     enter into a subcontract or other arrangement to have the other party
     provide up to five percent (5%) of the services, products and/or technology
     required under the contract and the non-contracting party shall receive its
     share of revenues accordingly.

          4.3    FACILITATING TRANSACTIONS.  Whenever a mutually satisfactory
     contract to provide services, products and/or technology to a Customer has
     been obtained by a party and the other party has provided limited
     solicitation assistance, such as by way of introduction, endorsement,
     referral or similar facilitating activity ("FACILITATING EFFORT"), the
     contracting party shall make a commercially reasonable good faith effort to
     enter into 


                                       2

<PAGE>

     a subcontract or other arrangement to have the party providing the 
     Facilitating Effort to provide up to five percent (5%) of the services,
     products and/or technology required under the contract and the party
     providing the Facilitating Effort shall receive its share of the revenues
     accordingly; PROVIDED, HOWEVER, that any contract under this Section 4.3
     entered into must have been entered into within one (1) year of the
     performance of the initial Facilitating Effort.

          4.4    LIMITATION.  Notwithstanding the foregoing, should it be
     discovered that any SAIC organization or affiliate other than the SAIC
     Financial Services Practice is marketing, performing or providing services,
     products and/or technology independently of the relationship described in
     this Agreement, no subcontracting shall be required by the other SAIC
     organization or affiliate with Carreker.

     5.   BUSINESS DEVELOPMENT COMMITMENT.

          5.1    During the first two (2) years of this Agreement, Carreker and
     SAIC agree to confer, develop, fund (either through the utilization of
     internal personnel, resources, facilities, equipment, products and/or other
     assets or by contributing cash) and implement mutually acceptable business
     development plans approved in advance in writing by Carreker's President
     and SAIC's Technology Solutions Sector Manager and which will consist of
     (a) a public relations promotional program (the "PR PROGRAM") and (b) the
     development of a joint marketing and sales plan such as, but not limited to
     an electronic commerce strategic plan.

          5.2    Each party shall equally contribute up to Twenty Thousand
     Dollars ($20,000) in value per year to fund the PR Program, subject to a
     maximum total contribution by each party of Forty Thousand Dollars
     ($40,000).

          5.3    Each party shall equally contribute up to One Hundred Thousand
     Dollars ($100,000) in value per year to fund the marketing and sales plan
     agreed mutually upon and referred to in Section 5.1 above, subject to a
     maximum total contribution by each party of Two Hundred Thousand Dollars
     ($200,000).

     6.   CONTRACTING.

          6.1    With respect to any undertaking proposed under this Agreement,
     the parties shall confer and determine which of them should be the party
     contracting with the Customer (the "PROJECT LEADER").

          6.2    Each party shall (i) provide appropriate information and
     personnel and use commercially reasonable good faith efforts to timely
     prepare and submit to the Project Leader such data as are required for use
     in preparation of that part of the proposal to be submitted to the Customer
     and the services, products and/or technology to be provided 


                                       3

<PAGE>

     to the Customer and (ii) provide all other reasonable assistance to the 
     Project Leader in preparation of a proposal.

          6.3    The Project Leader shall prepare the proposal, integrate the
     information and data provided by the parties, submit the proposal to the
     other party for advance review and written approval and submit the
     resulting proposal to the Customer.

          6.4    The Project Leader shall propose and promote the other party
     as the subcontractor for the services, products and/or technology to be
     provided under the contract with the Customer by such party.

          6.5    The parties shall perform such additional effort subsequent to
     submittal of the proposal to the Customer as appears reasonable to obtain
     the contract with the Customer.

          6.6    Each party shall perform its respective obligations described
     in the contract with the Customer in a proper and workmanlike manner and in
     accordance with the specifications, terms and conditions of the contract
     with the Customer.

          6.7    Any and all costs, expense or liability of either party caused
     by or arising out of this Agreement, its implementation, amendment, or
     expansion, shall be borne by each party separately and individually and
     neither party shall be liable or obligated to the other for any such cost,
     expense or liability except to the extent that such costs, expense, or
     liabilities are reimbursed, paid or provided for, under a written agreement
     entered into between the parties.

     7.   COMPLIANCE WITH LAW.  Each Party agrees that in carrying out its
duties and responsibilities under this Agreement, it will neither undertake, nor
cause nor permit to be undertaken any activity which either (a) is illegal under
any laws, decrees, rules or regulations in effect in the United States, any
state or territory or in any other applicable jurisdiction, or (b) would have
the effect of causing the other party to be in violation of any laws, decrees,
rules or regulations in effect in the United States, any state or territory or
in any other applicable jurisdiction.  Each party further acknowledges and
agrees that if either party breaches this Paragraph 7: (i) the non-breaching
party shall have the immediate right to terminate this Agreement; and (ii) the
breaching party shall indemnify the non-breaching party for any penalty, loss or
expenses incurred by the non-breaching party as a result of any such breach.

     8.   OWNERSHIP OF PRODUCTS AND WORK PRODUCT.  Any patent, trademark,
copyright or intellectual property right in any software, software enhancements,
products, services, technology, inventions, proprietary information or work
product ("PRODUCTS") produced or created solely by one party as a result of the
activities contemplated by this Agreement shall be the sole and exclusive
property of such party.  With respect to Products that are created directly as a
result of the combined work efforts of both parties (and not merely because the


                                       4

<PAGE>

contract with the Customer was jointly solicited), unless otherwise agreed in 
advance in a document signed by Carreker's President and SAIC's Technology 
Solutions Sector Manager, each party shall have a one-half (1/2) undivided 
interest in the Products without a duty to account to the other, provided 
that the Products are created or developed solely by the combined work 
efforts of the parties and not merely because the contract was jointly 
solicited.

     9.   CONFIDENTIAL AND/OR PROPRIETARY INFORMATION.

          9.1    The parties anticipate that under this Agreement it may be
     necessary for either to transfer to the other information of a confidential
     and/or proprietary nature ("CONFIDENTIAL INFORMATION").  Confidential
     Information shall be clearly identified by the disclosing party at the time
     of disclosure either by being marked with a legend clearly indicating that
     it is confidential or proprietary and all oral information that is reduced
     to writing and is identified as being confidential or proprietary and such
     writing is given to the recipient within fifteen (15) days of the date of
     the oral disclosure.  Any information otherwise provided shall be deemed to
     not be confidential or proprietary.

          9.2    Each of the parties agree that it will use the same efforts to
     protect such Confidential Information as are used to protect its own
     Confidential Information.  Disclosures of such Confidential Information
     shall be restricted to those individuals who are directly participating in
     the proposal and contracting efforts hereunder.

          9.3    Neither party shall make any reproductions, disclosure or use
     of such Confidential Information except in performing its obligations under
     this Agreement and as are set forth in the proposal to the Customer, with
     appropriate restrictive legends to the extent that either party
     specifically requests, and such legends as are permitted by the Customer's
     regulations.

          9.4    The limitations on reproduction, disclosure or use of
     Confidential Information shall not apply to, and neither party shall be
     liable for reproduction, disclosure or use of Confidential Information with
     respect to which any of the following conditions exist:

                 (a)     If, prior to the receipt thereof under this Agreement,
          it has been developed independently by the party receiving it, or was
          lawfully known to the party receiving it, or has been lawfully
          received from other sources, including the Customer, provided such
          other source did not receive it due to a breach of this Agreement;

                 (b)     If, subsequent to the receipt thereof under this
          Agreement, (i) it is published by the party furnishing it or is
          disclosed by the party furnishing it to others, including the
          Customer, without restriction, or (ii) it has been lawfully obtained
          by the party receiving it from other sources, including the Customer,


                                       5

<PAGE>

          provided such other source did not receive it due to a breach of this
          Agreement, or (iii) if such information otherwise comes within the
          public knowledge or becomes generally known to the public; or

                 (c)     If any part of the Confidential Information has been or
          hereafter shall be disclosed in a United States patent issued to the
          party furnishing the Confidential Information hereunder, then, after
          the issuance of said patent, the limitations on such Confidential
          Information as disclosed in the patent shall be only that afforded by
          the United States Patent Laws.

          9.5    Neither the execution and delivery of this Agreement, nor the
     furnishing of any Confidential Information by either party shall be
     construed as granting to the other party either expressly, by implication,
     estoppel, or otherwise, any license under any invention, patent, trademark,
     or copyright now or hereafter owned or controlled by the party furnishing
     same.

          9.6    Notwithstanding the expiration of the other portions of this
     Agreement, the obligations and provisions of this Article 9 shall continue
     until terminated by either party upon five (5) days written notice to the
     other; PROVIDED, HOWEVER, that the terms and conditions of this Article
     shall continue to apply to all Confidential Information disclosed prior to
     the effective date of such termination.

          9.7    Each of the parties shall identify a person responsible for
     receipt of Confidential Information subject to this Article.

neither party shall be entitled to receive or obligated to pay any damages in
connection with such termination.

     13.  ARBITRATION OF DISPUTES.  The parties agree that any controversy or

contract, tort or otherwise) arising out of or relating to this Agreement, any
performance or dealings between the parties, or any dispute arising out of the
interpretation or application of this Agreement, which the parties are not able
to resolve, shall be settled exclusively by arbitration in Dallas, Texas by a
single arbitrator pursuant to the American Arbitration Association's Commercial
Arbitration Rules then obtaining and judgment upon the award rendered by the

necessary disbursements incurred in addition to any other relief to which such
party may be entitled.

shall be governed by and interpreted as to substantive matters in accordance
with the applicable laws of the State of Texas (excluding its choice of law
rules).

                                                                  EXHIBIT 10.15

                             SETTLEMENT AGREEMENT

     This Settlement Agreement (this "Agreement"), dated as of January 29,
1998, is between Ronald R. Antinori, an individual ("Mr. Antinori"), and
Carreker-Antinori, Inc., a Texas corporation (the "Company").

                                   RECITALS

     Mr. Antinori was the majority shareholder of Antinori Software, Inc., a
Georgia corporation ("ASI").  On January 31, 1997, a wholly-owned subsidiary of
the Company merged with and into ASI, with the result that ASI then became a
wholly-owned subsidiary of the Company (the "Merger").

     The Merger occurred pursuant to that certain Agreement and Plan of Merger
dated as of January 29, 1997 between the Company (then named The Carreker
Group, Inc.), such wholly-owned subsidiary and ASI (the "Merger Agreement").

     In the Merger, Mr. Antinori received 458,007 shares of the Company's Class
A Voting Common Stock.

     Pursuant to that certain Escrow Agreement entered into as of January 31,
1997 among the Company, Mr. Antinori, Susan Antinori (Mr. Antinori's spouse),
Michael Israel and U.S. Trust Company of Texas, N.A., as escrow agent (the
"Antinori Escrow Agreement"), Mr. Antinori placed 22,873 shares of the
Company's Class A Voting Common Stock into an escrow account to secure
indemnification obligations to the Company and other Indemnified Persons (as
defined in Section 10.2 of the Merger Agreement).

     Subsequent to the Merger the parties have decided that an adjustment to
the relative valuation of ASI and the Company is appropriate for reasons
including, but not limited to, the developmental status of the "ASI 17" and
"Odyssey" products as of the closing date of the Merger.  Mr. Antinori and the
Company also desire to fully and finally settle certain claims, to avoid
continued or future disputes and controversies regarding those claims, to
provide peace of mind for both parties, and to eliminate and forego the
nuisance of possible litigation and the financial costs of such litigation.

     In consideration of the foregoing recitals and other good and valuable
consideration, the receipt and sufficiency of which the parties acknowledge,
the parties agree as follows:

     1.  CANCELLATION; RELEASE FROM ESCROW.  The 22,873 shares of the Company's
Class A Voting Common Stock that Mr. Antinori placed into the escrow
established by the Antinori Escrow Agreement shall be released to the Company,
for cancellation pursuant to the terms thereof.  An original or photocopy of
this Agreement, delivered to U.S. Trust Company of Texas, N.A., shall
constitute joint notice by the Company and Mr. Antinori, and direction to U.S.
Trust Company of Texas, N.A. per Section 4(b) of the Antinori Escrow Agreement,
that such 22,873 

<PAGE>

shares are to be released to the Company, for cancellation.

     In addition to the foregoing shares to be released from escrow, Mr.
Antinori, as the principal shareholder of ASI prior to the Merger, agrees to
return to the Company, on the earlier to occur of (a) Lawrence D. Duckworth's
exercise of his options on Company stock held by Mr. Antinori, as described in
Section 8, and (b) March 31, 1998, in either case for cancellation, an
additional 18,300 shares of the Company's Class A Voting Common Stock.  Such
shares, when combined with the shares to be released from escrow (as referred
to in the foregoing paragraph) by Mr. Antinori and two other former ASI
shareholders, in all cases valued at the per share value determined as of the
time of the Merger, are intended to effectuate an adjustment to reflect the
relative values of ASI and the Company at the time of the Merger.

     2.  RELEASE FROM ESCROW TO J.D. CARREKER.  In connection with Merger
Agreement, J.D. Carreker deposited 25,700 shares of the Company's Class A
Voting Common Stock into an escrow pursuant to that certain Escrow Agreement
entered into as of January 31, 1997 among the Company, Mr. Carreker and U.S.
Trust Company of Texas, N.A., as escrow agent (the "Carreker Escrow
Agreement").  An original or photocopy of this Agreement, delivered to U.S.
Trust Company of Texas, N.A., shall constitute joint notice by the Company and
Mr. Carreker, and direction to U.S. Trust Company of Texas, N.A. per Section
4(b) of the Antinori Escrow Agreement, that such 25,700 shares are to be
released to Mr. Carreker.

     3.  RECIPROCAL RELEASES.  In consideration of Mr. Antinori's agreements
made in this Agreement, the Company knowingly, voluntarily, and intentionally
agrees to, and does, settle, release, waive, and discharge Mr. Antinori and his
past, present and future affiliates, assigns, accountants, attorneys,
consultants and other representatives (collectively, the "Antinori Released
Parties"), from any and all claims and causes of action, whether legal,
equitable, or administrative, whether presently known or not known to the
Company, and whether fixed or contingent, that the Company and/or its
successors, assigns and/or any person on its behalf now holds, may ever hold or
has held, known or unknown and may have or claim to have now or in the future
against any one or more of the Antinori Released Parties, concerning any and
all matters arising in connection with or under the Merger Agreement and/or the
Antinori Escrow Agreement or by reason of the Merger; PROVIDED, HOWEVER, that
the foregoing shall not constitute a settlement, release, waiver, or discharge
of the Company's rights or obligations under (1) this Agreement, (2) that
certain Employment Agreement dated January 31, 1997 between Mr. Antinori and
the Company (as such Employment Agreement is amended as provided below) ("Mr.
Antinori's Employment Agreement"), (3) that certain Non-Competition Agreement
dated January 31, 1997 between Mr. Antinori and the Company, (4) that certain
Employee Confidentiality Agreement dated January 31, 1997 between Mr. Antinori
and the Company and (5) that certain Shareholders Agreement dated as of January
31, 1997 among the Company, Mr. Antinori and others (the "Shareholders
Agreement"), each of which shall survive this Agreement in accordance with its
terms.

     In consideration of the Company's agreements made in this Agreement, Mr.
Antinori 


SETTLEMENT AGREEMENT - Page 2

knowingly, voluntarily, and intentionally agrees to, and does, settle, 
release, waive, and discharge the Company, its predecessors, successors and 
past, present and future affiliates, employees, officers, directors, 
shareholders, partners, assigns, accountants, attorneys, consultants, other 
representatives, employee retirement, health and welfare benefit plans and 
the fiduciaries thereof and agents (collectively, the "Company Released 
Parties"), from any and all claims and causes of action, whether legal, 
equitable, or administrative, whether presently known or not known to Mr. 
Antinori, and whether fixed or contingent, that Mr. Antinori and/or his 
spouse, dependents, heirs, successors, and assigns and/or any person on his 
behalf now holds, may ever hold or has held, known or unknown and may have or 
claim to have now or in the future against any one or more of the Company 
Released Parties, concerning any and all matters arising in connection with 
or under the Merger Agreement and/or the Carreker Escrow Agreement or by 
reason of the Merger; PROVIDED, HOWEVER, that the foregoing shall not 
constitute a settlement, release, waiver, or discharge of Mr. Antinori's 
rights or obligations under (1) this Agreement, (2) Mr. Antinori's Employment 
Agreement (as amended as provided below), (3) that certain Non-Competition 
Agreement dated January 31, 1997 between Mr. Antinori and the Company, (4) 
that certain Employee Confidentiality Agreement dated January 31, 1997 
between Mr. Antinori and the Company and (5) that certain Shareholders 
Agreement dated as of January 31, 1997 among the Company, Mr. Antinori and 
others (the "Shareholders Agreement"), each of which shall survive this 
Agreement in accordance with its terms.

     4.  AMENDMENT OF SECTION 1 OF MR. ANTINORI'S EMPLOYMENT AGREEMENT.  The
first sentence of Section 1 of Mr. Antinori's Employment Agreement is hereby
amended and restated to provide in its entirety as follows:

     "Carreker will employ Mr. Antinori and Mr. Antinori accepts
     employment with Carreker for a period of two years from January 31,
     1997 (such two year period being the "INITIAL PERIOD")."

In addition, references in Section 8 to an Initial Period of two or three years
are hereby amended to be references to an Initial Period of two years,
consistent with the foregoing amendment above.

     5.  AMENDMENT OF SECTION 4 OF MR. ANTINORI'S EMPLOYMENT AGREEMENT.
Section 4 of Mr. Antinori's Employment Agreement is hereby amended and restated
to provide in its entirety as follows:

          "Mr. Antinori's salary for the first year of the Initial Period
     will be not less than $350,000.  Mr. Antinori shall be entitled to a
     salary increase in the second year of the Initial Period if
     Carreker's board of directors so determines or if Mr. J.D. Carreker
     receives a salary increase in respect of such second year (in which
     event the salary increases shall be matched on a dollar-for-dollar
     basis), but not otherwise.  All salary is payable on Carreker's
     regular payroll dates, less required withholdings.  Mr. Antinori
     acknowledges that determinations of salary increases, if any, are
     within the sole and complete discretion of Carreker's board of
     directors.


SETTLEMENT AGREEMENT - Page 3

<PAGE>

          Mr. Antinori shall not receive a bonus for the fiscal year
     ending January 31, 1998 unless Mr. J.D. Carreker receives a bonus for
     such fiscal year, in which event their bonuses for such fiscal year
     shall be in the same proportion as are their salaries for such fiscal
     year.  If and to the extent the board of directors of Carreker
     establishes a bonus pool for the fiscal year ending January 31, 1999,
     then Mr. Antinori will be entitled to participate in the same, with
     the amount, if any, of his bonus to be determined based upon the
     bonus paid to Mr. J.D. Carreker in respect of such fiscal year, in
     which case their bonuses shall be in the same proportion as are their
     salaries.  In determining Mr. Antinori's bonuses, if any, credit will
     be given to Company contributions to his profit-sharing account, if
     any.  Mr. Antinori acknowledges that the establishment of a bonus
     pool is within the sole and complete discretion of Carreker's board
     of directors.

          To the extent that the state tax liability of Mr. Antinori is
     reduced as a result of the agreement by the parties to file ASI state
     tax returns on a multistate apportionment basis as provided in
     Section 7 of that certain Settlement Agreement of even date herewith
     between the parties, then the Company shall be entitled to reduce
     bonus payments otherwise payable to Mr. Antinori by the amount of any
     such reduction.  Such reduction shall be determined on an annual
     basis during each fiscal year of this Agreement.  If Mr. Antinori
     receives a reduction of his state tax liability after all bonuses
     have been paid pursuant to this Agreement, or if such reduction
     exceeds the bonuses owing pursuant to this Agreement, then Mr.
     Antinori shall pay the amount of such reduction (or the amount of
     such excess) to the Company promptly.  The provisions of this Section
     4 shall survive the termination of this Agreement."

     6.  LAPSE OF RESTRICTIONS ON STOCK HELD BY ISRAEL.  Pursuant to a letter
agreement between ASI and Michael Israel dated December 20, 1994, ASI issued to
Mr. Israel, on a restricted basis, one percent (1%) of ASI's outstanding
shares.  The Company agrees to not take a tax reporting position on its income
tax returns that conflicts with Mr. Antinori's taking a tax deduction based on
the lapse of restrictions on such shares.  However, if on June 1, 1999, Mr.
Antinori (either directly, or indirectly through ASI) has not taken such tax
deduction, or has taken a tax reporting position that conflicts with his taking
such tax deduction, then, as between Mr. Antinori and the Company, the Company
may take such tax deduction, and Mr. Antinori agrees to not take, on and after
June 1, 1999, a tax reporting position on his income tax returns that conflicts
with the Company's taking of such deduction.  The party taking the foregoing
tax deduction in accordance with this Section 6 shall bear any tax preparation
costs, or any other costs, associated with this benefit to him or it,
respectively.

     7.  STATE TAX MATTERS.  The parties agree that (a) beginning with the tax
year ending December 31, 1996 and ending with the tax period ending on or
before the effective date of the Merger, all state tax returns of ASI shall be
filed on a multistate apportionment basis, (b) amended state tax returns of ASI
for Georgia for tax years ending December 31, 1994 and 


SETTLEMENT AGREEMENT - Page 4

<PAGE>

December 31, 1995 shall be filed allocating income to Georgia on a multistate 
apportionment basis, and (c) state tax returns for North Carolina (and any 
other state as determined in the sole discretion of the Company) shall be 
filed on a multistate apportionment basis for the tax year ending December 
31, 1996 (and any other year or other period as determined in the sole 
discretion of the Company).  The Company agrees to assume the defense of and 
shall have complete control of any audit of any state tax return or any other 
proceeding instituted by any state taxing authority with respect to income 
tax liability of ASI (or Antinori, if the same relates to the business 
operations of ASI).  The Company agrees to indemnify and hold Antinori 
harmless from any tax liability and expenses relating to any audit or other 
proceeding instituted by any state taxing authority to the extent that such 
liability (i) exceeds Antinori's tax liability as reported on any tax return 
for such state, or (ii) relates to any state tax liability if no state tax 
return in respect of such liability was filed by ASI prior to January 31, 
1997; PROVIDED, HOWEVER, that the Company shall have no liability to 
indemnify or hold Antinori harmless unless the tax liability relates to the 
business operations of ASI.  Antinori will fully cooperate with the Company 
(i) in filing state tax returns and amendments thereto in a manner consistent 
with this Section 7 and (ii) in connection with any audit or other proceeding 
instituted by a state taxing authority.

     The foregoing indemnity shall not apply to the extent that ASI (and/or Mr.
Antinori, in respect of the business operations of ASI) has liability to
Georgia for taxes in excess of taxes reported and paid to Georgia for tax years
through and including December 31, 1995 and, for the tax year ended December
31, 1996, to the extent that such liability to Georgia for taxes is in excess
of the amount of taxes that would have been reported and paid to Georgia if the
applicable tax returns had not been prepared on a multistate apportionment
basis.

     Mr. Antinori represents that as of the date of this Agreement he has fully
and completely disclosed, and in the future will fully and completely disclose,
the status of all pertinent tax matters, including (a) responses and other
negotiations and communications to and from taxing authorities and (b) the
nature and status of all tax liabilities and tax refunds, and will cause his
professional tax advisors to make themselves reasonably available, at no
expense to the Company, to provide such information with respect to the
foregoing when and as requested by the Company.

     8.  DUCKWORTH OPTION ON ANTINORI SHARES.  Mr. Antinori and the Company
agree to cooperate, through the use of reasonable commercial efforts, to cause
Lawrence D. Duckworth's exercise of his options on shares of Company stock held
by Mr. Antinori to occur prior to the expiration thereof on March 30, 1998, as
to 24,445 such shares.  Mr. Antinori hereby acknowledges that such options are
exercisable by Mr. Duckworth, and that the total number of such options
exercisable after the adjustments triggered by reason of the first paragraph of
Section 1 hereof is 48,889.  Nothing herein shall modify the terms and
conditions of such options, specifically including the purchase price thereof
of $4.3816 per share and the expiration date thereof of March 30, 1998.

     9.  NO ADMISSION OF WRONG-DOING.  Entry into this Agreement does not, in
any way, constitute an admission of improprieties or other wrong-doing by any
party hereto.

     10.  FULL DISCLOSURE OF AGREEMENTS WITH LAWRENCE D. DUCKWORTH.  Mr.
Antinori represents to the Company that there are no agreements, arrangements
or understandings between Mr. Antinori and Lawrence D. Duckworth, or between
Mr. Duckworth and/or his affiliates, considered as one party in interest, and
Mr. Antinori and/or his affiliates, considered as another party in interest, in
both cases whether formal or informal, oral or in writing, except as disclosed
to the Company previously, in writing, by Mr. Antinori and attached to this
Agreement as ATTACHMENT A.

     11.  SURVIVAL.  This Agreement, together with the agreements referenced in
the provisos of Section 3 above as not being settled, waived, released or
discharged, contains all of the terms, provisions, and understandings between
Mr. Antinori and the Company.  No modification of this Agreement can be made
except in writing and signed by both parties.

     12.  ARBITRATION.  Any Dispute (as defined in the Merger Agreement)
arising in connection with this Agreement will be subject to arbitration in the
same manner as a Dispute arising in connection with the Merger Agreement, i.e.,
as provided in Section 11.1 of the Merger Agreement.

     13.  MISCELLANEOUS.  This Agreement is binding on the parties and their
representatives, heirs, and successors and assigns.  This Agreement shall be
governed by and interpreted under the laws of the State of Texas, without
regard to conflict of laws.  Mr. Antinori acknowledges that the Company makes
no representation whatsoever concerning the tax consequences, if any, of this
Agreement to him.  Each party agrees that, except as expressly provided to the
contrary in Section 7, such party is solely responsible for payment of all of
such party's federal, state, and local taxes, interest and penalties, if any,
which are or may become due on account of this Agreement and agrees to
indemnify, defend and hold harmless the other party from any liability for such
amounts.  Each party represents and warrants to the other party that no claims
settled, released, waived or discharged herein have been previously conveyed,
assigned, or transferred in any manner, whether in whole or in part, to any
person, entity, or other third party.  Each party represents to the other that
such party is relying on its or his, as applicable, own judgment in entering
into this Agreement, and is not relying (and has not relied) on any statement
or representation, not expressly set forth herein, of such other party (or any
agent or affiliate of such other party).  Mr. Antinori expressly represents
that he is competent and authorized to release and/or waive any claims he may
have against the Company that are released and/or waived hereby.  If any
portion of this Agreement (other than Section 1 hereof) is deemed
unenforceable, void, voidable, or of no force and effect, then no other portion
will be thereby affected, and the remainder of this Agreement will continue in
full force and effect.  This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument; but in pleading or
proving this Agreement, or any provision hereof, it shall not be necessary to
produce or introduce any more than one of

such counterparts.  MR. ANTINORI ACKNOWLEDGES AND AGREES THAT HE HAS THE 
RIGHT TO DISCUSS ALL ASPECTS OF THIS AGREEMENT WITH A PRIVATE ATTORNEY, HAS 
BEEN ENCOURAGED TO DO SO BY THE COMPANY, AND HAS DONE SO TO THE EXTENT HE 
DESIRES.  MR. ANTINORI REPRESENTS AND AGREES THAT HE HAS THOROUGHLY AND

                             SETTLEMENT AGREEMENT

     This Settlement Agreement (this "Agreement"), dated as of January 29,
1998, is between Susan Antinori, an individual ("Mrs. Antinori"), and Carreker-
Antinori, Inc., a Texas corporation (the "Company").

                                   RECITALS

     Mrs. Antinori was a shareholder of Antinori Software, Inc., a Georgia
corporation ("ASI").  On January 31, 1997, a wholly-owned subsidiary of the
Company merged with and into ASI, with the result that ASI then became a wholly-
owned subsidiary of the Company (the "Merger").

     The Merger occurred pursuant to that certain Agreement and Plan of Merger
dated as of January 29, 1997 between the Company (then named The Carreker
Group, Inc.), such wholly-owned subsidiary and ASI (the "Merger Agreement").

     In the Merger, Mrs. Antinori received 51,461 shares of the Company's Class
A Voting Common Stock.

     Pursuant to that certain Escrow Agreement entered into as of January 31,
1997 among the Company, Mrs. Antinori, Ronald R. Antinori (Mrs. Antinori's
spouse), Michael Israel and U.S. Trust Company of Texas, N.A., as escrow agent
(the "Antinori Escrow Agreement"), Mrs. Antinori placed 2,570 shares of the
Company's Class A Voting Common Stock into an escrow account to secure
indemnification obligations to the Company and other Indemnified Persons (as
defined in Section 10.2 of the Merger Agreement).

     Subsequent to the Merger the parties have decided that an adjustment to
the relative valuation of ASI and the Company is appropriate for reasons
including, but not limited to, the developmental status of the "ASI 17" and
"Odyssey" products as of the closing date of the Merger.  Mrs. Antinori and the
Company also desire to fully and finally settle certain claims, to avoid
continued or future disputes and controversies regarding those claims, to
provide peace of mind for both parties, and to eliminate and forego the
nuisance of possible litigation and the financial costs of such litigation.

     In consideration of the foregoing recitals and other good and valuable
consideration, the receipt and sufficiency of which the parties acknowledge,
the parties agree as follows:

     1.  CANCELLATION; RELEASE FROM ESCROW.  The 2,570 shares of the Company's
Class A Voting Common Stock that Mrs. Antinori placed into the escrow
established by the Antinori Escrow Agreement shall be released to the Company,
for cancellation pursuant to the terms thereof.  An original or photocopy of
this Agreement, delivered to U.S. Trust Company of Texas, N.A., shall
constitute joint notice by the Company and Mrs. Antinori, and direction to U.S.
Trust Company of Texas, N.A. per Section 4(b) of the Antinori Escrow Agreement,
that such 2,570 shares are to be released to the Company, for cancellation.

     2.  RELEASE FROM ESCROW TO J.D. CARREKER.  In connection with Merger
Agreement, J.D. Carreker deposited 25,700 shares of the Company's Class A

                             SETTLEMENT AGREEMENT

     This Settlement Agreement (this "Agreement"), dated as of January 29,
1998, is between Michael Israel, an individual ("Mr. Israel"), and Carreker-
Antinori, Inc., a Texas corporation (the "Company").

                                   RECITALS

     Mr. Israel was a shareholder of Antinori Software, Inc., a Georgia
corporation ("ASI").  On January 31, 1997, a wholly-owned subsidiary of the
Company merged with and into ASI, with the result that ASI then became a wholly-
owned subsidiary of the Company (the "Merger").

     The Merger occurred pursuant to that certain Agreement and Plan of Merger
dated as of January 29, 1997 between the Company (then named The Carreker
Group, Inc.), such wholly-owned subsidiary and ASI (the "Merger Agreement").

     In the Merger, Mr. Israel received 5,146 shares of the Company's Class A
Voting Common Stock.

     Pursuant to that certain Escrow Agreement entered into as of January 31,
1997 among the Company, Mr. Israel, Ronald R. Antinori, Susan Antinori and U.S.
Trust Company of Texas, N.A., as escrow agent (the "Antinori Escrow
Agreement"), Mr. Israel placed 257 shares of the Company's Class A Voting
Common Stock into an escrow account to secure indemnification obligations to
the Company and other Indemnified Persons (as defined in Section 10.2 of the
Merger Agreement).

     Subsequent to the Merger the parties have decided that an adjustment to
the relative valuation of ASI and the Company is appropriate for reasons
including, but not limited to, the developmental status of the "ASI 17" and
"Odyssey" products as of the closing date of the Merger.  Mr. Israel and the
Company also desire to fully and finally settle certain claims, to avoid
continued or future disputes and controversies regarding those claims, to
provide peace of mind for both parties, and to eliminate and forego the
nuisance of possible litigation and the financial costs of such litigation.

     In consideration of the foregoing recitals and other good and valuable
consideration, the receipt and sufficiency of which the parties acknowledge,
the parties agree as follows:

     1.  CANCELLATION; RELEASE FROM ESCROW.  The 257 shares of the Company's
Class A Voting Common Stock that Mr. Israel placed into the escrow established
by the Antinori Escrow Agreement shall be released to the Company, for
cancellation pursuant to the terms thereof.  An original or photocopy of this
Agreement, delivered to U.S. Trust Company of Texas, N.A., shall constitute
joint notice by the Company and Mr. Israel, and direction to U.S. Trust Company
of Texas, N.A. per Section 4(b) of the Antinori Escrow Agreement, that such
2,570 shares are to be released to the Company, for cancellation.

<PAGE>

     2.  RELEASE FROM ESCROW TO J.D. CARREKER.  In connection with Merger
Agreement, J.D. Carreker deposited 25,700 shares of the Company's Class A
Voting Common Stock into an escrow pursuant to that certain Escrow Agreement
entered into as of January 31, 1997 among the Company, Mr. Carreker and U.S.
Trust Company of Texas, N.A., as escrow agent (the "Carreker Escrow
Agreement").  An original or photocopy of this Agreement, delivered to U.S.
Trust Company of Texas, N.A., shall constitute joint notice by the Company and
Mr. Carreker, and direction to U.S. Trust Company of Texas, N.A. per Section
4(b) of the Antinori Escrow Agreement, that such 25,700 shares are to be
released to Mr. Carreker.

in this Agreement, the Company knowingly, voluntarily, and intentionally agrees
to, and does, settle, release, waive, and discharge Mr. Israel and his past,

     2.6    Set forth on EXHIBIT A is a list of each location at which tangible
Collateral is kept, whether for storage, like purposes, or otherwise.  Also set
forth on EXHIBIT A is a list of each office of Borrower at which records of
Borrower pertaining to Accounts are kept and of Borrower's chief executive
office.

     2.7    Subject to any limitations stated therein or in connection
therewith, (a) all balance sheets, earnings statements, and other financial data
which have been or may hereafter be furnished to Bank to induce it to enter into
this Agreement, or otherwise furnished in connection herewith, do or shall
fairly represent the financial condition and results of operations of Borrower
(or other entity, as applicable), as of the dates and for the periods for which
the same are furnished, in accordance with generally accepted accounting
principles consistently applied, and (b) Bank all other information, reports,
and other papers and data furnished to Bank shall be accurate, as of the
relevant date, and correct in all material respects and complete insofar as
completeness may be necessary to give Bank a true and accurate knowledge of the
subject matter.  Neither this Agreement, nor any document, certificate, or
statement furnished to Bank by or on behalf of Borrower pursuant to or in
connection with this Agreement contains any untrue statement of a material fact
or omits to state a material fact necessary to make the statements contained
herein and therein not misleading.  There is no fact known to Borrower that
materially and adversely affects, or will materially and adversely affect, the
assets, business, operations, or condition of Borrower that has not been
specifically set forth in this Agreement or otherwise disclosed by Borrower to
Bank in writing.

     2.8    Except as specifically disclosed by Borrower to Bank, in EXHIBIT B,
there are no actions, suits, or proceedings pending or, to the knowledge of
Borrower, threatened against Borrower at law, or in equity, or by or before any
governmental department, commission, board, bureau, agency, or instrumentality,
or any arbitrator, that are not at least eighty percent (80%) covered by
insurance or which involve in the aggregate more than Twenty-Five Thousand
Dollars ($25,000.00).


                                       6

     2.9    Borrower is not engaged in the business of extending credit for the
purpose of purchasing or carrying "margin" stock within the meaning of
Regulation U of the Board of Governors of the Federal Reserve System (12 C.F.R.
Part 221), as amended from time to time ("Regulation U").  No funds borrowed
pursuant to this Agreement shall be used for the purpose, whether immediate,
incidental, or ultimate, of purchasing or carrying within the meaning of
Regulation U, any "margin stock" as defined therein, unless exempt under
Regulation U.

     2.10   Prior to the execution of this Agreement, Borrower is solvent,
having assets of a value that exceeds the amount of its liabilities.  Taking
into consideration the considerable value of the Collateral securing the
Liabilities directly incurred by Borrower, and the satisfactory value of the
rights of subrogation and contribution that Borrower would enjoy in the event it
is required to satisfy the obligations hereunder, Borrower reasonably
anticipates that it will be able to meet its debts as they mature.  Borrower has
adequate capital to conduct the business in which it is engaged.  The acceptance
by Borrower of advances hereunder shall be deemed to be a representation and
warranty to Bank that Borrower is solvent at the time of such advance, and
otherwise that the representations and warranties of Borrower in this Agreement
are true and correct as if made again on the date of such advance.

     SECTION 3.   BANK'S AGREEMENT TO MAKE LOAN.

     3.1    Subject to the terms and conditions of this Agreement, and so long
as no Event of Default or event which with notice or the passage of time would
constitute an Event of Default, as defined below or under any other document or
instrument executed in connection herewith shall have occurred or be continuing,
from the date hereof until July 1, 1998, or such future date to which the
expiration date of the Note may be extended (the "Termination Date"), Bank
agrees to extend to Borrower an open-end line of credit on the basis of seventy
percent (70%) of the value of Borrower's Eligible Accounts (such advance formula
being hereinafter referred to as the "Borrowing Base"); provided, however, that
in no event shall the aggregate sum of all advances made by Bank to Borrower
under its Revolving Line exceed Borrower's Line Limit (as defined below). 
Within such Line Limit, Borrower may borrow, repay, and reborrow hereunder, from
the date of this Agreement until the Termination Date.  The Line Limit for
Borrower shall be $3,000,000.00.

     3.2    All borrowings under the Revolving Line shall be evidenced by the
Note and by entering such advances as debits to Borrower's Loan Account.  Bank
also shall record in Borrower's Loan Account other charges, expenses, and items
properly chargeable to Borrower hereunder, all payments made by Borrower on
account of its indebtedness thereunder, and other appropriate debits and
credits.  The debit balance of Borrower's Loan Account shall reflect the amount
of Borrower's indebtedness under its Revolving Line from time to time hereunder.
Notwithstanding the foregoing, no failure by Bank to properly reflect any
advance actually made or any such charge, expense, or item actually incurred in
any Borrower's Loan Account shall relieve Borrower from its obligations with
respect thereto.  At least once each month, Bank shall render a statement of
account for Borrower's Loan Account.  Each such statement shall be considered
correct and accepted by Borrower and conclusively binding upon Borrower except
to the extent that Bank receives a written notice of Borrower's exceptions
within thirty (30) days after such statement has been mailed by ordinary mail to
Borrower.


                                       7

<PAGE>

     3.3    If at any time the sum of the outstanding balance of any Borrower's
Loan Account exceeds the lesser of its (i) Borrowing Base or (ii) Line Limit,
then Borrower immediately shall remit to Bank good funds sufficient to eliminate
such excess.  If a Borrower fails immediately to remit to Bank good funds
sufficient to eliminate such excess, Bank may, without notice to or demand on
Borrower, at Bank's option (in addition to and without waiving any and all other
rights and remedies of Bank) apply against such excess (x) any collections on
and Proceeds from Accounts Receivable forwarded to Bank and/or in Bank's
possession; (y) any other property of Borrower and the Proceeds thereof now or
hereafter held by Bank (whether for safekeeping, custody, pledge, transmission,
collection or otherwise); and (z) Borrower's' deposit balances (general or
special) and credits with Bank.  Borrower shall repay to Bank on the Termination
Date the aggregate amount in Borrower's Loan Account at the close of business on
the Termination Date.

     3.4    In the event that the availability of advances expires by the terms
of this Agreement, or by the terms of any agreement extending the expiration
date of this Agreement, Bank may, in its sole discretion, make requested
advances; however, it is expressly acknowledged and agreed that, in such event,
Bank shall have the right, in its sole discretion, to decline to make any
requested advance and may require payment in full of Borrower's Loan Account
without prior notice to Borrower and the making of any such advances shall not
be construed as a waiver of such right by Bank.

     3.5    Borrower shall pay interest on the principal amount of the
Revolving Line from time to time at a per annum interest rate equal to the Index
Rate, but in no event shall the interest rate exceed the Highest Lawful Rate. 
All payments of principal and interest that are past due shall, at the option of
Bank, bear interest at the lesser of a rate equal to the Index Rate or the
Highest Lawful Rate.

     3.6    All funds borrowed under the Revolving Line shall be used for
working capital and general corporate purposes.

     Nothing in this Section shall be deemed to extend the duration of the Loans
beyond the times noted in Section 14 hereof.

     SECTION 4.   INSPECTION OF RECORDS; FURTHER ASSURANCE.

     4.1    Borrower shall at reasonable times and from time to time allow
Bank, by or through any of its officers, agents, employees, attorneys, or
accountants (i) to examine, inspect, or make extracts from Borrower's' books and
records; (ii) to analyze financial statements; (iii) to arrange for verification
of Accounts under reasonable procedures, directly with Account Debtors or by
other methods; and (iv) to inspect tangible property constituting Collateral
(all the foregoing collectively referred to as "Audits").  Audits by Bank, may
be at any time during normal business hours, without prior notice to Borrower. 
The reasonable expense of such Audits shall be paid by Borrower.

     4.2    Borrower shall do, make, execute and deliver all such additional
and further acts, things, deeds, assurances and instruments which Bank may
require more completely to vest in and assure to Bank its rights hereunder or in
any Collateral.


                                       8

<PAGE>

     4.3    Borrower shall pay an annual monitoring fee of $2,500.00 to Bank.

     SECTION 5.   SECURITY INTEREST OF BANK IN COLLATERAL.

     5.1    As security for the payment and performance of all Liabilities,
Bank shall have and is hereby granted a continuing lien on, a security interest
in and a right of set-off against the following Collateral:

     (a)    all Accounts of Borrower, whether now or hereafter existing,
            created, arising or acquired;

     (b)    all Inventory of Borrower, whether now or hereafter existing,
            created, arising or acquired;

     (c)    all general intangibles of Borrower, whether now or hereafter
            existing, created, arising, or acquired;

     (d)    all books and records now owned and hereafter acquired relating to
            Collateral and all files, correspondence, computer programs, tapes,
            disks and related data processing software owned Borrower or in
            which Borrower has an interest that contains information concerning
            or relating to Collateral or any item thereof; and

     (e)    all Proceeds and products of all of the foregoing, including,
            without limitation, insurance proceeds.

No submission by Borrower to Bank of any schedule or other particular
identification of Collateral shall be necessary to vest in Bank a security
interest in each and every item of Collateral now existing or hereafter
acquired, but rather, such security interest shall vest in Bank immediately upon
the creation or acquisition of any item of Collateral, without the necessity for
any other or further action by Borrower or Bank.

     5.2    To the extent applicable, the Texas Business and Commerce Code
governs the security interests provided for herein.  In connection therewith,
Borrower shall take such steps and execute and deliver such financing statements
and other papers as Bank may from time to time request.

     5.3    If, by reason of location of Collateral or otherwise, the creation,
validity, or perfection of security interests provided for herein are governed
by the law of a jurisdiction other than Texas, Borrower shall take such steps
and execute and deliver such papers as Bank may from time to time request to
comply with the Uniform Commercial Code, the Uniform Trust Receipts Act, the
Factors Lien Act, the Federal Food Security Act, or other laws of other states
or jurisdictions.  Borrower hereby appoints and empowers Bank, or any employee
of Bank which Bank may designate for the purpose, as attorney-in-fact, to
execute on its behalf any financing statements which, in Bank's sole judgment,
are necessary to be filed in order to perfect or preserve the perfection of
Bank's security interests granted hereby.


                                       9

<PAGE>

     5.4    As additional security for the payment and performance of all
Liabilities, Borrower shall obtain and maintain or cause to be maintained, with
a financially sound and reputable insurer acceptable to Bank, such acceptance
not to be unreasonably withheld, life insurance with respect to the life of J.
Denny Carreker having a death benefit of at least $1,000,000.00 while any of the
Liabilities are outstanding and unpaid.  Such life insurance policy shall
provide that such policy may not be cancelled, amended, or terminated unless at
least thirty (30) days prior written notice thereof has been given to Bank.  In
addition, such insurance policy shall be assigned by Borrower to Bank to secure
the prompt payment, performance and observance in full of the Liabilities.  All
insurance proceeds received by Bank under such policy shall be retained by Bank
for application to the payment of such portion of the Liabilities and in such
order as Bank may determine in its sole discretion with the balance, if any, to
be disbursed to Borrower.  Borrower shall furnish Bank with an original or, at
Bank's option, a certificate of such insurance policy prior to and as a
condition to the receipt of any advance hereunder.  Borrower shall deliver to
Bank each renewal policy or a certificate pertaining thereto at least fifteen
(15) days before the expiration date of such policy.

     SECTION 6.   COLLECTION OF ACCOUNTS.

     6.1    (a)   Until Borrower is notified by Bank to the contrary, Borrower
            shall have the right to collect Accounts and deposit proceeds
            received from Account Debtors into operating accounts of Borrower
            maintained at Bank.

     (b)    If Bank at any time determines in good faith that the financial
            condition of Borrower or its ability to repay the Liabilities has
            materially changed to the detriment of Bank, then Bank may, at its
            option, notify Borrower that it must immediately establish a
            remittances account maintained by and in the name of Bank (the
            "Remittances Account") for the deposit of each and every remittance
            with respect to the Accounts, and in such event, Borrower shall
            provide contemporaneously with each and every remittance with
            respect to the Accounts and upon each deposit of funds to the
            Remittances Account to Bank, a report reflecting the amount of all
            such remittances, the Accounts and amounts thereof with respect to
            which such remittances were made.  Thereafter, Borrower shall
            notify Bank of such collections as are received pursuant to the
            provisions of Section 7.1 below and shall hold the proceeds
            received from collections in trust for Bank without commingling the
            same with other funds of Borrower and shall turn the same over to
            Bank immediately upon receipt in the identical form received. 
            Proceeds so transmitted to Bank may be handled and administered in
            and through remittance or special accounts; the maintenance of any
            such accounts shall be solely for the convenience of Bank, and
            Borrower shall not have any right, title, or interest in or to any
            such accounts or in the amounts at any time appearing to the credit
            thereof.

     (c)    Following an Event of Default or event which following notice or
            the passage of time would constitute an Event of Default, Bank may
            (without notice to or demand on Borrower, at Bank's option) apply
            against the outstanding balance of Borrower's Loan Account from
            time to time any collections on and Proceeds from Accounts
            Receivable forwarded to Bank and/or in Bank's possession
            (including, 


                                      10

<PAGE>

            without limitation, any such collections and Proceeds in any 
            lock-box, Remittances Account or any operating or other account 
            maintained by or for Borrower at Bank).  Nothing herein shall be 
            deemed to diminish or limit any of Bank's rights or remedies under
            applicable law or Section 3.3, Section 10, Section 11, or any other
            Section of this Agreement or otherwise.  If no Event of Default has
            occurred or is continuing hereunder and if there is no excess 
            outstanding balance in Borrower's Loan Account required to be paid 
            by Borrower under Section 3.3 hereof, Bank may, at its option, 
            deposit any or all collections on and Proceeds from Accounts 
            Receivable in Bank's possession into Borrower's operating accounts 
            maintained and to be maintained at Bank.  Bank shall not be required
            to credit Borrower's Loan Account with the amount of any check or 
            other instrument constituting provisional payment until Bank has 
            received final payment thereof at its office in cash or solvent 
            credits accepted by Bank.

     (d)    Borrower shall, at the request of Bank, notify the Account Debtors
            of the security interest of Bank in any Account and shall instruct
            Account Debtors to remit payments directly to Bank, and Bank may
            itself, at any time, so notify Account Debtors.

     6.2    Borrower agrees that no court action or other legal proceeding or
garnishment, attachment, repossession of property, or any other attempt to
repossess any merchandise covered by an Account shall be attempted by Borrower
except by or under the direction of competent legal counsel.  Borrower hereby
agrees to indemnify and hold Bank harmless from any loss or liability of any
kind or character which may be asserted against Bank by virtue of any suit
filed, process issued, or any repossession or attempted repossession done or
attempted by Borrower or by virtue of any other endeavors which Borrower may
make to collect any Accounts or repossess any such merchandise.

     SECTION 7.   AFFIRMATIVE COVENANTS.

     Until all indebtedness of Borrower to Bank has been paid and all
Liabilities have been satisfied, Borrower shall furnish or cause to be furnished
to Bank:

     7.1    (a)   together with each request for an advance, or if not
            previously furnished, within twenty (20) days following the end of
            each calendar month, detailed reports in form acceptable to Bank of
            all Accounts as of the last day of the immediately preceding
            calendar month, and the period of time which has elapsed with
            respect to such Accounts since the invoice date with respect
            thereto;

     (b)    together with each request for an advance, or if not previously
            furnished, within twenty (20) days following the end of each

            Certificate in the forms attach hereto as EXHIBIT C, as of the last
            day of the immediately preceding calendar month signed by an
            authorized officer of the applicable Borrower;

     (c)    if requested by Bank, monthly, within twenty (20) days following
            the end of each calendar month, a report reflecting the amount of
            all deposits to operating

            respect to which deposits were made;

     (d)    monthly financial statements of Borrower, which may be internally

            the close of such period, an income statement, and reconciliation
            of surplus for such period, prepared and analyzed in accordance
            with generally accepted accounting principles consistently applied
            and attested to by an authorized officer of Borrower;

            statement, and reconciliation of surplus for such period, prepared
            by an outside certified public accountant reasonably satisfactory
            to Bank in accordance with generally accepted accounting principles
            consistently applied;

     (f)    a copy of Borrower's federal income tax returns within thirty (30)
            days following the filing thereof with the Internal Revenue
            Service;

     (g)    such other documents, instruments, data, or information of any type
            requested by Bank with respect to the Accounts, or other Collateral
            or Borrower's operations or financial condition.

     7.2    Borrower shall (a) maintain insurance in form, amount, and
substance acceptable to Bank including, without limitation, extended multi-peril
hazard, worker's compensation, and general liability insurance written by
companies reasonably acceptable to Bank upon all facets of its business,
including without limitation, the Collateral pledged to Bank, its property, and
its equipment, of such character and amounts as are usually maintained by
companies engaged in like business; (b) furnish to Bank, upon request, a
statement of the insurance coverage; (c) obtain other or additional insurance
promptly, upon request of Bank, to the extent that such insurance may be
available; and (d) cause Bank to be named as loss payee as to all property
constituting Collateral hereunder, pursuant to a loss payable endorsement in
form acceptable to Bank.

     7.3    Borrower shall maintain with Bank its primary operating and
depository accounts ("Depository Accounts"), and Bank, at Bank's option, may
make all advances hereunder into Borrower's Depository Accounts, and Borrower
expressly agrees that Bank may, at Bank's option, debit against any such
Depository Accounts any and all sums, amounts, charges, and payments due under
or in connection with this Agreement and/or the Note.

     7.4    Borrower does and shall at all times comply with all present and
future laws, ordinances, rules, and regulations (of any governmental authority
or entity) applicable to, governing or affecting Borrower, its operations, its
property, the Collateral, or any part of any of the foregoing, and shall
immediately notify Bank of any and all alleged or asserted violations of any
such law, ordinance, or regulation.


                                      12

<PAGE>

     7.5    Borrower shall at the time of its first knowledge or notice
immediately notify Bank in writing of (i) the occurrence of any event or the
existence of any event, circumstance, or condition which constitutes or upon
notice or lapse of time would constitute an Event of Default under the terms of
this Agreement and (ii) any other information that may adversely affect in any
material manner the assets of Borrower including, but not limited to, the filing
of any lawsuit against or involving Borrower.

     7.6    Borrower agrees to indemnify Bank, its officers, directors,
employees, agents and attorneys ("Indemnified Parties") and hold them harmless
against any and all claims, demands, causes of action, loss, damage,
liabilities, costs and expenses (including, without limitation, attorneys' fees
and court costs) asserted against or incurred by Indemnified Parties by reason
of, arising out of, or in connection with, any fact or circumstance relating to
the transactions made the subject of this Agreement or the Security Documents or
any of them.  The above notwithstanding Borrower shall have no obligation to
indemnify or hold harmless Bank from claims resulting from the gross negligence
or intentional misconduct of Bank.

     7.7    Borrower agrees to take all actions that Bank may request to
establish and maintain a valid security interest in the Accounts and each and
every other item of Collateral, free and clear of all other liens, claims,
charges, security interests, and encumbrances whatsoever.  Borrower shall
promptly pay all taxes or charges levied on or with respect to the Collateral,
and will at all times keep the Accounts and each and every other item of
Collateral free and clear of all liens, claims, charges, security interests, and
encumbrances whatsoever, other than the security interest granted hereby or by
any other document executed in favor of Bank.  If such taxes or other
assessments remain unpaid after the date fixed for the payment of same, or if
any lien, charge, claim, security interest, or encumbrance shall arise, or be
claimed or asserted with respect to the Accounts or any other item of
Collateral, Bank may, without notice to Borrower, pay such taxes, assessments,
charges, or claims, and take any and all other actions (including the payment of
money) deemed desirable by Bank to remove any such lien, charge, claim, security
interest, or encumbrance, and Borrower agrees that the amounts thereof shall be
charged to Borrower's Loan Account created hereby and shall bear interest at the
rate of interest then borne by Borrower's obligations under the Note.  Not
withstanding the other provisions of this Section 7.7, nothing herein shall
require the payment or discharge of any such taxes or assessments so long as
Borrower (a) shall, in good faith, and at its own expense, contest the same or
the validity thereof by appropriate legal proceedings diligently pursued; and
(b) shall, at Bank's option, post a bond or provide other security deemed
equivalent by Bank to cover or secure payment of such taxes or assessments.

     Nothing in this Section shall be deemed to extend the duration of the Loans
beyond the times noted in Section 14 hereof.

     SECTION 8.   NEGATIVE COVENANTS.

     8.1    Borrower shall not create or permit the creation or continuance of
any lien, charge, encumbrance, or other interest upon any of its property,
except for liens (collectively, "Permitted Liens") (a) for taxes, assessments or
governmental charges not yet payable; (b) of landlords and vendors arising in
the ordinary course of business for sums not yet due; and (c) approved in
advance in writing by Bank or listed on EXHIBIT D attached hereto.  Borrower
will not sell, 


                                      13

<PAGE>

transfer, lease or otherwise dispose of, or suffer to exist any lien, charge, 
claim, security interest, or encumbrance (except for those in favor of Bank) 
with respect to any of the Collateral or any interest therein (or any of the 
Proceeds thereof, whether money, checks, money orders, drafts, notes, 
instruments, documents, chattel paper, Accounts, returns, or repossessions), 
without Bank's prior written consent.

     8.2    Without Bank's prior written consent, Borrower shall not borrow any
money, or otherwise become directly or indirectly obligated, other than for
trade credit in the ordinary course of business and the existing indebtedness
listed on EXHIBIT D attached hereto, and Borrower shall not guarantee, endorse,
or assume, either directly or indirectly, any indebtedness of any other
corporation, person, or entity.

     8.3    Without Bank's prior written consent, Borrower shall not purchase
or acquire, directly or indirectly, any shares of stock, evidences of
indebtedness, or other securities of any person, corporation, or other entity. 
Without Bank's prior written consent, Borrower shall not lend, make advances or
otherwise extend credit to any person or entity.

     8.4    Borrower shall not liquidate, or discontinue or materially reduce
its normal operations with intention to liquidate, and shall not merge or
consolidate with or into any corporation, partnership, or other entity, or sell,
lease, transfer, or otherwise dispose of all or any substantial part of its
assets, or any of its Accounts.  Borrower shall not cause, allow, or suffer to
occur a change in the ownership or management of Borrower or its business
without Bank's prior written consent.  Borrower will not change its name or
identity without notifying Bank of such change in writing at least thirty (30)
days prior to the effective date of such change, and Borrower will take all
steps necessary prior to any such change to maintain at all times the priority
and validity of all liens and security interests contemplated by this Agreement,
and will execute and deliver to Bank all financing statement amendments
requested by Bank prior to such name change becoming effective.

     8.5    Without Bank's prior written consent, Borrower shall not declare or
pay any dividends or bonuses (unless payable in shares of a Borrower) upon

Borrower agrees to execute any additional financing statements or other

to perform any act or obligation imposed under this Agreement or the Note or
under any other agreement to which Bank and Borrower are parties.

     SECTION 10.  POWER TO SELL OR COLLECT COLLATERAL; REMEDIES CUMULATIVE.

     10.1   Upon the occurrence of any one or more of the above Events of
Default and at any time thereafter (such defaults not having been previously
cured), Bank shall have, in addition to all other rights and remedies, the
remedies of a secured party under the Texas Business and Commerce Code
(regardless of whether the Uniform Commercial Code has been enacted in the
jurisdiction where rights or remedies are asserted), including, without
limitation, the right to take possession of the Collateral, and for that purpose
Bank may, so far as Borrower can give authority therefor, enter upon any
premises on which the Collateral may be situated and remove the same therefrom
or take possession of same and store same on such premises pending disposition
under the terms of this Agreement or applicable law.  Bank may require Borrower
to assemble the Collateral and make it available to Bank at a place designated
by Bank.  Unless the Collateral is perishable or threatens to decline speedily
in value or is to a type customarily sold on a recognized market, Bank shall
give to Borrower at least five (5) days' written notice of the time and place of
any public sale of Collateral or of the time after which any private sale or any
other intended disposition is to be made, which time period shall be deemed for
all purposes to be commercially reasonable.  Bank may, at any time in its
discretion. transfer any securities or other property constituting Collateral
into its own name or that of its nominee, and receive the income thereon and
hold the same as security for the Liabilities or apply it on principal or
interest due on Liabilities.  Insofar as Collateral shall consist of Accounts,
insurance policies, instruments, chattel paper, choices in action, or the like,
Bank may demand, collect, receipt for, settle, compromise, adjust, sue for,
release, extend the time of payment, make allowances and adjustments, foreclose,
or realize upon Collateral as Bank may determine, whether or not Liabilities or
Collateral are then due, and for the purpose of realizing Bank's rights therein,
Bank is granted power of attorney to receive, open, and dispose of mail
addressed to Borrower and endorse notes, checks, drafts, money orders, documents
of title, or other evidences of payment, shipment, or storage or any form of
Collateral on behalf of and in the name of Borrower.

     10.2   No right, power, or remedy conferred in this Agreement, the Note,
or any other agreement executed in connection herewith or any other document or
agreement to which Borrower and Bank are parties, or now or hereafter existing
at law, in equity, or admiralty, by statute or otherwise, shall be exclusive,
and each such right, power, or remedy, shall, to the full extent permitted by
law, be cumulative and in addition to every other such night, power, or remedy.


                                      17

<PAGE>

     10.3   The sale by Bank of less than the whole of the Collateral shall not
exhaust the rights of Bank hereunder, and Bank is specifically empowered to make
successive sales hereunder until the whole of the Collateral shall be sold.  If
the proceeds of any sale of less than the whole of the Collateral shall be less
than the aggregate of the Liabilities, this Agreement and the security interests
created hereby shall remain in full force and effect as to the unsold portion of
the Collateral just as though no sale had been made, provided, however, that
Borrower shall never have any right to require sale of less than the whole of
the Collateral but Bank shall have the right, at its sole election, to sell less
than the whole of the Collateral.

     10.4   Bank may resort to any security given by this Agreement or to any
other security now existing or hereafter given to secure the payment of
Borrower's Liabilities, in whole or in part, and in such portions and in such
order as may seem best to Bank in its sole discretion, and any such action shall
not in any way be considered as a waiver of any of the rights, benefits, or
security interests evidenced by this Agreement.

     10.5   Bank may, at all times, proceed directly against Borrower to
enforce payment of Borrower's Liabilities and shall not be required first to
enforce its rights in the Collateral or any other security granted to it.  Bank
shall not be required to take any action of any kind to preserve, collect, or
protect it or Borrower's rights in the Collateral or any other security granted
to it.

     SECTION 11.  DEPOSITS.

     Bank, any participant, and any other holder of all or any part of the
Liabilities are hereby given a continuing lien as additional security for all
Liabilities hereunder upon any and all moneys, securities, and other property of
Borrower, and the Proceeds thereof, now or hereafter held or received by or in
transit to Bank, such participant, or such holder from or for Borrower, whether
for safekeeping, custody, pledge, transmission, collection, or otherwise, and
also upon any and all deposit balances (general or special) and credits of
Borrower with. and any and all claims of Borrower against Bank, such
participant, or such holder at any time existing, and upon an event of default
hereunder, Bank, such participant, or such holder may apply or set off the same
against the Liabilities and indebtedness hereby secured, without notice and
without liability.  Borrower agrees that any other person or entity purchasing a
participation from Bank may exercise all its rights of payment (including the
right of set-off) with respect to such participation as fully as if such person
or entity was the direct creditor of Borrower in the amount of such
participation.

     SECTION 12.  WAIVERS.

     Borrower and each accommodation party, surety, endorser, or other person or
entity liable for the payment or collection of the Liabilities expressly waive
demand, presentment for payment, notice of protest, notice of intent to
accelerate, notice of acceleration, notice of acceptance of this Agreement, and
notice of loans made, credit extended, Collateral received or delivered, or
other action taken in reliance hereon and all other demands and notices of any
description.  With respect both to the Liabilities and Collateral, Borrower
consents to any extension or postponement of the time of payment or any other
indulgence, to any substitution, exchange, or release of any or all of the
Collateral, to the addition or release of any party or person primarily or
secondarily 


                                      18

<PAGE>

liable, to the acceptance of partial payments thereon and the settlement, 
compromising, or adjusting of any thereof, all in such manner and at such 
time or times as Bank may deem advisable.  Bank shall have no duty as to the 
collection or protection of any or all of the Collateral or any income 
thereon, nor as to the preservation of any rights pertaining thereto beyond 
the safe custody of Collateral without resorting or regard to other 
collateral or sources of reimbursement for the Liabilities.  Bank shall not 
be deemed to have waived any of its rights upon or under any of the 
Liabilities or Collateral unless such waiver be in writing and signed by 
Bank.  No course of dealing and no delay or omission on the part of Bank in 
exercising any right shall operate as a waiver of such right or any other 
right.  A waiver on any one occasion shall not be construed as a bar to or 
waiver of any right on any further occasion.  All rights and remedies of Bank 
with respect to Liabilities or Collateral, whether evidenced hereby or by any 
other instrument or paper, shall be cumulative and may be exercised singly or 
concurrently.

     SECTION 13.  EXPENSES, PROCEEDS OF COLLATERAL.

     Irrespective of whether the proceeds of the Note are disbursed, Borrower
shall pay all expenses, including, without limitation, reasonable legal
expenses, incurred by Bank from time to time in connection with the preparation,
administration, amendment, or modification of this Agreement, the Note, and
other documents executed in connection with the creation of the Loans and those
associated with the perfection and creation of the security interests granted
pursuant hereto.  Borrower shall pay to Bank on demand any and all expenses and
costs of collection, including, without limitation, reasonable counsel fees,
incurred or paid by Bank in protecting or enforcing its rights upon or with
respect to any of the Liabilities or the Collateral.  After deducting all of
said expenses, the residue of any proceeds of collection or sale of Liabilities
or Collateral shall be applied to the payment of principal or interest on
Liabilities in such order or preference as Bank may determine, proper allowance
for interest on Liabilities not then due being made, and any excess shall be
returned to Borrower, and Borrower shall remain liable for any deficiency.

     SECTION 14.  DURATION; EXTENSION.

     The Revolving Line shall terminate on the Termination Date; however, the
parties recognize that they may wish to extend the expiration date by mutual
agreement.  The termination or expiration of the Revolving Line shall in no way
affect any transactions entered into or rights created or obligations incurred
prior to such termination or expiration; rather, such rights and obligations
shall be fully operative until the same are fully disposed of, concluded, and/or
liquidated.  Without limiting the generality of the foregoing, such termination
or expiration shall not release nor diminish any of Borrower's' obligations and
agreements hereunder until payment in full of all of the Liabilities under this
Agreement and all other sums and amounts payable under or pursuant to this
Agreement.  This Agreement shall be a continuing agreement in every respect.  No
modification or amendment of this Agreement or extension of the Termination Date
shall be effective unless placed in writing and duly executed by Bank and
Borrower.

     SECTION 15.  GENERAL.

     15.1   All notices or other communications required or permitted to be
given pursuant to this Agreement shall be in writing and shall be considered as
properly given if mailed by first

class United States mail, postage prepaid, registered or certified with 
return receipt requested, or by delivering same to the designated address of

Notice given in any other manner shall be effective only if and when received

     Attention: Mr. Jerry Hopkins

     IF TO BORROWER:

     Carreker-Antinori, Inc.
     1400 North Dallas Parkway, Suite 1100
     Dallas, Texas 75240
     Attn: Mr. J. Denny Carreker

     15.2   If at any time or times by assignment or otherwise Bank transfers
any of the Liabilities (either separately or together with the Collateral
therefor), such transfer shall carry with it Bank's powers and rights under this
Agreement with respect to the Liabilities and Collateral transferred, and the
transferee shall become vested with said powers and rights whether or not they
are specifically referred to in the transfer.  If and to the extent Bank retains
any other of the Liabilities or Collateral, Bank will continue to have the
rights and powers herein set forth with respect thereto.

     15.3   This Agreement and all rights and obligations hereunder, including,
matters of constriction, validity, and performance, shall be governed by the
laws of the State of Texas, except that Tex. Rev. Civ. Stat. Ann. art.
5069-1.04, as amended, Ch. 15, which regulates certain revolving credit loan
accounts and revolving tri-party accounts, shall not apply to this Agreement,
the Note, the Revolving Line, or any transaction contemplated hereby.  Unless
changed in accordance with law, the applicable rate under Texas law shall be the
indicated (weekly) rate ceiling from time to time in effect as provided in Tex.
Rev. Civ. Stat. Ann. art. 5069-1.04, as amended.

     15.4   This Agreement is performable in Dallas County, Texas, and any
action brought for the enforcement or construction of any term of this Agreement
or any of the Note or other instruments executed in connection herewith shall be
brought in a court of appropriate jurisdiction in Dallas County, Texas.

     15.5   It is the intention of Bank and Borrower to conform strictly to any
applicable usury laws.  Accordingly, if the transactions contemplated hereby
would be usurious under any applicable law, then, in that event, notwithstanding
anything to the contrary in this Agreement, 


                                      20

<PAGE>

the Note, or any other agreement or instrument entered into in connection 
with or as security for or guaranteeing this Agreement or the Note, it is 
agreed as follows: (i) the aggregate of all consideration that constitutes 
interest under applicable law that is contracted for, taken, reserved, 
charged, or received by Bank under this Agreement, the Note, or under any 
other agreement entered into in connection with or as security for or 
guaranteeing this Agreement or the Note shall under no circumstances exceed 
the Highest Lawful Rate (as defined below), and any excess shall be cancelled 
automatically and, if theretofore paid, shall, at the option of Bank, be 
credited by Bank on the principal amount of any indebtedness owed to Bank by 
Borrower or refunded by Bank to Borrower, and (ii) in the event that the 
maturity of the Note or any other of the Liabilities are accelerated or in 
the event of any required or permitted prepayment, then such consideration 
that constitutes interest under law applicable to Bank may never include more 
than the Highest Lawful Rate and excess interest, if any, provided for in 
this Agreement or the Note or otherwise shall be cancelled automatically as 
of the date of such acceleration or prepayment and, if theretofore paid, 
shall, at the option of Bank, be credited by Bank on the principal amount of 
any indebtedness owed to Bank by Borrower or refunded by Bank to Borrower.

     15.6   Notwithstanding anything herein to the contrary, in no event will
interest payable to Bank exceed the maximum amount permitted by the law
applicable to Bank (after taking into account all charges payable to Bank that
constitute interest under such applicable law), but if any amount referred to in
any of this Agreement, the Note, or any other agreement or instrument to which
Bank and Borrower are parties that would be payable to Bank but for the
applicability of usury or other laws limiting the consideration payable to Bank
is not paid to Bank as a result of the applicability of such laws, then interest
on the outstanding principal balance of the Liabilities payable to Bank shall,
to the extent permitted by law, accrue at the Highest Lawful Rate (after taking
into account all charges payable to Bank that constitute interest under
applicable law) until the total amount received by Bank equals the amount it
would have received had no such laws been applicable.

     15.7   "HIGHEST LAWFUL RATE" means the maximum non-usurious interest rate
(computed on the basis of a year of 365 or 366 days, as applicable) that at any
time or from time to time may be contracted for, taken, reserved, charged or
received on amounts due to Bank, under laws applicable to Bank that are
presently in effect or, to the extent allowed by law, under such applicable laws
which allow a higher maximum non-usurious rate than applicable laws now allow.

     15.8   This Agreement and the documents delivered hereunder or in
connection herewith contain the entire agreement between the parties with
respect to the subject matter hereof and thereof and supersede all prior
agreements relating to the subject matter hereof and thereof In the event of
actual conflict in the terms and provisions of this Agreement and any of such
documents or any other instrument or agreement executed in connection with this
Agreement or described or referred to in this Agreement, the terms and
provisions of this Agreement shall control.  No modification, consent, amendment
or waiver or any provision of this Agreement, nor consent to any departure by
Borrower therefrom, shall be effective unless the same shall be in writing and
signed by Bank, and then shall be effectively only in the specific instance and
for the purpose for which given.  This Agreement is binding upon Borrower, its
heirs, successors and assigns, and inures to the benefit of Bank, its successors
and assigns.  All representations and warranties of Borrower herein, and all
covenants and agreements herein or in any document delivered 


                                      21

<PAGE>

hereunder or in connection herewith that are not fully performed before the 
effective date of this Agreement, shall survive such date.

     15.9   Prior to the date of this Agreement, Bank and Borrower have entered
into one or more loan agreements ("Prior Loan Agreements") relating to one or
more extensions of credit including extensions of credit renewed and extended by
this Agreement and the Note and other extensions of credit which are not
evidenced by the Note.  To the extent any term or provision of the Prior Loan
Agreements is in conflict with the terms and provisions of this Agreement, the
terms and provisions of this Agreement shall control and supersede all such
Prior Loan Agreements.

     15.10  If at any time after the date hereof, and from time to time, Bank
determines that the adoption or modification of any applicable law, rule or
regulation regarding taxation, Bank's required levels of reserves, deposits,
insurance or capital (including any allocation of capital requirements or
conditions), or similar requirements, or any interpretation or administration
thereof by any governmental authority, central bank or comparable agency charged
with the interpretation, administration or compliance of Bank with any of such
requirements, has or would have the effect of (i) increasing Bank's costs
relating to the Loans, or (ii) reducing the yield or rate of return of Bank on
the Loans, to a level below that which Bank could have achieved but for the
adoption or modification of any such requirements, Borrower shall, within
fifteen (15) days of any request by Bank, pay to Bank such additional amounts as
(in Bank's sole judgment, after good faith and reasonable computation) will
compensate Bank for such increase in costs or reduction in yield or rate of
return of Bank; provided, however, that nothing herein contained shall be
construed or so operate as to require Borrower to pay any interest, fees, costs
or charges greater than is permitted by applicable law.  No failure by Bank to
immediately demand payment of any additional amounts payable hereunder shall
constitute a waiver of Bank's right to demand payment of such amounts at any
subsequent time.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of
the date first above written.

to, and are being administered and operated (and have at all times been 
administered and operated) in material compliance with, the requirements of 
ERISA, the Internal Revenue Code ("CODE") and all other applicable ERISA and 
Code Regulations (including code provisions governing entitlement to 
deductions claimed by Company or any exemption or non-taxable benefit claimed 
or provided to any Plan participant).  All returns, reports and disclosure 
statements required to be made under the Code or ERISA with respect to all

ERISA.

           (b)      Except as is set forth in Section 3.19 of the Disclosure 
Schedule, each such qualified Benefit Plan has been determined by the 
Internal Revenue Service to be so qualified, and such determination remains 
in effect and has not been revoked.  Nothing has occurred since the date of 
any such determination that is reasonably likely to affect adversely such 
qualification or exemption, or result in the imposition of excise taxes or 
income taxes on unrelated business income under ERISA with respect to any 
Benefit Plan.

           (c)      The Company does not have a defined benefit plan subject 
to Title IV of ERISA.  The Company does not have a current or contingent 
obligation to contribute to any 

                                      -9-

threatened claims by or on behalf of any Benefit Plans, or by or on behalf of 
any individual participants or beneficiaries of any Benefit Plans, alleging 
any breach of fiduciary duty on the part of the Company or any of its 
officers, directors or employees under ERISA or any other applicable 
regulations, or claiming benefit payments other than those made in the 
ordinary operation of such plans, nor is there, to the knowledge of the 
Company, any basis for such claim.  The Benefit Plans are not the subject of 
any pending or, to the knowledge of the Company, threatened investigation, 
audit or action by the Internal Revenue Service, the Department of Labor or

prospects of the Company or on the Company's ability to conduct its business 
in any area.  There is no matter as to which the Company has received any 
notice, claim or assertion, or which otherwise has been threatened or which 
reasonably is expected to be threatened or initiated against or involving any 
director, officer, employee, agent or representative of the Company, nor is 
there any reasonable basis therefor, in connection with which any such person

against in the Balance Sheet;

           (b)      Liabilities incurred subsequent to the date of the

of general application) of any court or administrative agency, that would 
interfere with the use of his or her best efforts to promote the interests of 
the Company or that would conflict with the Company's business as proposed to 
be conducted. Neither the execution nor delivery of this Agreement nor the 
carrying on of the Company's business by the employees of the Company, nor 
the conduct of the Company's business as proposed, will, to the Company's or 
Carreker's knowledge, conflict with or result in a breach of the terms, 
conditions or provisions of, or constitute a default under, any contract, 
covenant or instrument under which any of such employees is now obligated, 
which conflict or default would be materially adverse to the Company, its 
properties or its business.

expenses not unusual in amount or significance.  The consummation of the 
transactions contemplated by this Agreement will not (either alone, or upon 
the occurrence of any act or event or with the lapse or time, or both) result 
in any benefit or payment (severance or other) arising or becoming due from 
the Company to any Shareholder, director, officer, employee or consultant of 
the Company (other than any benefit which may result from the Company's 
payment of attorneys' fees, accountants' fees and other customary and

("TAX RETURNS").  Such Tax Returns, including amendments to date, reflect 
completely and accurately in all material respects all liability for taxes of 
the Company for the periods covered thereby, whether or not due and payable 
and whether or not disputed.  To the Company's knowledge, all Taxes payable 
by, or due from, the Company have been fully paid or adequately disclosed and 
fully provided for in the books and financial statements of the Company.  To 
the Company's knowledge, no state of facts exists which would constitute 
grounds for the assertion of a deficiency by any federal, state or local tax 
authority for any Tax with respect to any post-Closing tax period which, if 
adversely determined, would have a material adverse effect on the Company.  
To the Company's knowledge, no examination of any Tax Return of the Company 
currently is in progress.  There are no outstanding agreements or waivers 
extending the statutory period of limitation applicable to any Tax Return of 
the Company.  The Company's Federal tax identification number is 75-1622836.

                             STRATEGIC ALLIANCE AGREEMENT

       THIS STRATEGIC ALLIANCE AGREEMENT ("AGREEMENT"), is made effective as of
October __, 1996, by and between SCIENCE APPLICATIONS INTERNATIONAL CORPORATION,
a Delaware corporation ("SAIC"), and THE CARREKER GROUP, INC., a Texas 
corporation ("CARREKER"), who agree as follows:

       1.    RECITALS.  This Agreement is entered into in contemplation of the
following facts and circumstances:

             1.1    OBJECTIVES.  Carreker and SAIC desire to establish an
       arrangement whereby they can in the future jointly offer such services,
       products and technology as they may possess to prospective users of the
       services, products and/or technology the parties may offer with
       particular emphasis on commercial financial institutions and federal
       government agencies ("CUSTOMERS") pursuant to terms, conditions and
       prices mutually agreed upon by the parties in advance of entering any
       contract with a Customer.  The parties also anticipate that each may
       identify opportunities which they do not pursue jointly, but with
       respect to which the services, products and/or technology of the other
       party may be marketed and sold to a Customer.  This Agreement pertains
       only to the SAIC Financial Services Practice within SAIC's Technology
       Solutions Sector (the "SAIC FINANCIAL SERVICES PRACTICE").

             1.2    PURPOSE.  This Agreement (a) sets forth (i) the provisions
       and conditions pursuant to which either party may identify and advise
       the other party of a mutually beneficial business opportunity and
       (ii) the circumstances under which parties may pursue the opportunity
       jointly, and (b) establishes the basis of payments to a party that
       introduces an opportunity which is not pursued jointly but with respect
       to which the other party successfully markets and sells its services,
       products and/or technology.

       2.    SCOPE OF AGREEMENT.  The parties specifically acknowledge and
agree that this Agreement shall not apply to any work or contracts that
commenced prior to the date of this Agreement, unless the parties otherwise
agree in writing.  This Agreement is not an exclusive dealings agreement and
each party is free to do business with others with respect to Customers or
otherwise; PROVIDED, HOWEVER, during the first three (3) years of this
Agreement, Carreker shall provide SAIC with a preferential opportunity to
provide services, products and/or technology to each prospective Customer that
Carreker solicits in those instances where it appears to Carreker that a teaming
relationship is necessary and that SAIC could provide the services, products
and/or technology that is the subject matter of the solicitation.

       3.    MUTUAL BUSINESS OPPORTUNITIES.

             3.1    REPRESENTATIVES.  Each party shall designate one or more
       authorized representatives to interact with the other for purposes
       hereof ("REPRESENTATIVE") until such time as either party notifies the
       other of its decision to designate a new Representative.

             3.2    REVIEW OF OPPORTUNITIES.  The parties' Representatives may
       select and submit to the other for its consideration such business
       opportunities identified by a party that the party believes may be of
       mutual interest and the Representatives shall jointly determine whether
       to pursue such business opportunity together.  If the parties determine
       to pursue an opportunity jointly, they also shall determine the terms,
       conditions and prices that will be offered to the prospective Customer
       and the strategy by which the parties will attempt to acquire the
       business (including, without limitation, designation of the party which
       shall serve as the prime contractor, the party which will perform the
       necessary services and provide the appropriate products and/or
       technology, and the party which will assume responsibility for
       presentation of the parties' proposal).  The Representatives shall meet
       and confer, either in person or by teleconference, at least once
       monthly, to discuss prospective business opportunities and performance
       with respect to existing accounts.

             3.3    COOPERATION.  If the parties pursue a business opportunity
       jointly, each party shall utilize commercially reasonable efforts to
       market and obtain the targeted business; PROVIDED, HOWEVER, that the
       parties shall coordinate their activities so as to provide a unified
       presentation to the prospective Customer.

       4.    TRANSACTIONS.

             4.1    JOINT TRANSACTIONS.  Whenever a mutually satisfactory
       contract to perform or provide services, products and/or technology to a
       Customer has been obtained due to the active and substantial marketing
       and sales efforts of both parties, Carreker will have the right to
       provide services, products and/or technology having a value up to fifty
       percent (50%) of the estimated value of the contract and Carreker shall
       be entitled to its proportion of the revenue derived from the services,
       products and/or technology provided by Carreker.  SAIC shall provide or
       obtain all services, products and/or technology not provided by Carreker
       and shall receive the revenue represented by the proportion of the
       revenue derived from the services, products and/or technology provided
       by SAIC.

             4.2    SOLE EFFORTS TRANSACTIONS.  Whenever a mutually satisfactory
       contract to provide services, products and/or technology to a Customer
       has been obtained by the sole marketing and sales efforts of such party,
       the contracting party shall make a commercially reasonable good faith
       effort to enter into a subcontract or other arrangement to have the
       other party provide up to five percent (5%) of the services, products
       and/or technology required under the contract and the non-contracting
       party shall receive its share of revenues accordingly.

             4.3    FACILITATING TRANSACTIONS.  Whenever a mutually satisfactory
       contract to provide services, products and/or technology to a Customer
       has been obtained by a party and the other party has provided limited
       solicitation assistance, such as by way of introduction, endorsement,
       referral or similar facilitating activity ("FACILITATING EFFORT"), the
       contracting party shall make a commercially reasonable good faith effort
       to enter into a subcontract or other arrangement to have the party
       providing the Facilitating Effort to provide up to five percent (5%) of
       the services, products and/or technology required under the contract and
       the party providing the Facilitating Effort shall receive its share of
       the revenues accordingly; PROVIDED, HOWEVER, that any contract under
       this Section 4.3 entered into must have been entered into within one (1)
       year of the performance of the initial Facilitating Effort.

             4.4    LIMITATION.  Notwithstanding the foregoing, should it be
       discovered that any SAIC organization or affiliate other than the SAIC
       Financial Services Practice is marketing, performing or providing
       services, products and/or technology independently of the relationship
       described in this Agreement, no subcontracting shall be required by the
       other SAIC organization or affiliate with Carreker.

       5.    BUSINESS DEVELOPMENT COMMITMENT.

             5.1    During the first two (2) years of this Agreement, Carreker
       and SAIC agree to confer, develop, fund (either through the utilization
       of internal personnel, resources, facilities, equipment, products and/or
       other assets or by contributing cash) and implement mutually acceptable
       business development plans approved in advance in writing by Carreker's
       President and SAIC's Technology Solutions Sector Manager and which will
       consist of (a) a public relations promotional program (the "PR PROGRAM")

       7.    COMPLIANCE WITH LAW.  Each Party agrees that in carrying out its

cause nor permit to be undertaken any activity which either (a) is illegal under
any laws, decrees, rules or regulations in effect in the United States, any

services, technology, inventions, proprietary information or work product 
("PRODUCTS") produced or created solely by one party as a result of the 
activities contemplated by this Agreement shall be the sole and exclusive 
property of such party.  With respect to Products that are created directly 
as a result of the combined work efforts of both parties (and not merely 
because the contract with the Customer was jointly solicited), unless 
otherwise agreed in advance in a document signed by Carreker's President and 
SAIC's Technology Solutions Sector Manager, each party shall have a one-half 
(1/2) undivided interest in the Products without a duty to account to the 
other, provided that the Products are created or developed solely by the

       9.    CONFIDENTIAL AND/OR PROPRIETARY INFORMATION.

             9.1    The parties anticipate that under this Agreement it may be
       necessary for either to transfer to the other information of a
       confidential and/or proprietary nature ("CONFIDENTIAL INFORMATION"). 
       Confidential Information shall be clearly identified by the disclosing
       party at the time of disclosure either by being marked with a legend
       clearly indicating that it is confidential or proprietary and all oral
       information that is reduced to writing and is identified as being
       confidential or proprietary and such writing is given to the recipient
       within fifteen (15) days of the date of the oral disclosure.  Any
       information otherwise provided shall be deemed to not be confidential or
       proprietary.

             9.2    Each of the parties agree that it will use the same efforts
       to protect such Confidential Information as are used to protect its own
       Confidential Information.  Disclosures of such Confidential Information
       shall be restricted to those individuals who are directly participating
       in the proposal and contracting efforts hereunder.

             9.3    Neither party shall make any reproductions, disclosure or
       use of such Confidential Information except in performing its
       obligations under this Agreement and as are set forth in the proposal to
       the Customer, with appropriate restrictive legends to the extent that
       either party specifically requests, and such legends as are permitted by
       the Customer's regulations.

             9.4    The limitations on reproduction, disclosure or use of
       Confidential Information shall not apply to, and neither party shall be
       liable for reproduction, disclosure or use of Confidential Information
       with respect to which any of the following conditions exist:

                    (a)    If, prior to the receipt thereof under this
             Agreement, it has been developed independently by the party
             receiving it, or was lawfully known to the party receiving it, or
             has been lawfully received from other sources, including the
             Customer, provided such other source did not receive it due to a
             breach of this Agreement;


                               Exhibit 5.06 - 5

<PAGE>

                               EXHIBIT 5.06

                    (b)    If, subsequent to the receipt thereof under this
             Agreement, (i) it is published by the party furnishing it or is
             disclosed by the party furnishing it to others, including the
             Customer, without restriction, or (ii) it has been lawfully
             obtained by the party receiving it from other sources, including
             the Customer, provided such other source did not receive it due to
             a breach of this Agreement, or (iii) if such information otherwise
             comes within the public knowledge or becomes generally known to
             the public; or

                    (c)    If any part of the Confidential Information has been
             or hereafter shall be disclosed in a United States patent issued
             to the party furnishing the Confidential Information hereunder,
             then, after the issuance of said patent, the limitations on such
             Confidential Information as disclosed in the patent shall be only
             that afforded by the United States Patent Laws.

             9.5    Neither the execution and delivery of this Agreement, nor
       the furnishing of any Confidential Information by either party shall be
       construed as granting to the other party either expressly, by
       implication, estoppel, or otherwise, any license under any invention,
       patent, trademark, or copyright now or hereafter owned or controlled by
       the party furnishing same.

             9.6    Notwithstanding the expiration of the other portions of this
       Agreement, the obligations and provisions of this Article 9 shall
       continue until terminated by either party upon five (5) days written
       notice to the other; PROVIDED, HOWEVER, that the terms and conditions of
       this Article shall continue to apply to all Confidential Information
       disclosed prior to the effective date of such termination.

             9.7    Each of the parties shall identify a person responsible for
       receipt of Confidential Information subject to this Article.

       10.   RELATIONSHIP OF PARTIES.

             10.1   INDEPENDENT CONTRACTORS.  The parties hereto intend that the
       relationship between them created by this Agreement shall be that of
       independent contractors and that the relationship shall continue as such
       as long as this Agreement remains in effect.  Nothing contained in this
       Agreement shall be construed to constitute either party as a partner,
       employee or agent of the other, and no employee or agent of either party
       shall be or be deemed to be the employee or agent of the other.

             10.2   SCOPE OF AGREEMENT.  Neither party shall have the authority
       to make any agreement or commitment, or incur any liability on behalf of
       the other party, nor shall either party be liable for any acts,
       omissions to act, contracts, commitments, promises or representations
       made by the other, except as specifically authorized in this Agreement
       or as the parties hereafter may agree in writing.

                                SHAREHOLDER AGREEMENT

       THIS SHAREHOLDER AGREEMENT (this "AGREEMENT") is made and entered into
as of October __, 1996 by and among THE CARREKER GROUP, INC., a Texas
corporation (the "COMPANY"), J.D. CARREKER ("CARREKER") and SCIENCE APPLICATIONS
INTERNATIONAL CORPORATION, a Delaware corporation ("SAIC").

                                       RECITALS

       WHEREAS, the Company and SAIC desire to form a strategic alliance
between them, because of their diverse and complementary capabilities;

       WHEREAS, the Company is authorized to issue shares ("SHARES") of the
Company's no par value Class A (voting) and Class B (non-voting) common stock
(individually "CLASS A COMMON STOCK") and "CLASS B COMMON STOCK") and
collectively "COMMON STOCK");

       WHEREAS, in connection with the formation of the strategic alliance SAIC
desires to make an investment in the Company by purchasing 100,645 Shares of the
Company's Class A Common Stock ("SAIC SHARES") pursuant to a Stock Purchase
Agreement to be executed by the Company and SAIC contemporaneously with this
Agreement;

       WHEREAS, Carreker presently owns 655,514 Shares (approximately 79.41%)
of the issued and outstanding Shares of Class A Common Stock (the "CARREKER
SHARES");

       WHEREAS, upon the consummation of the purchase and sale of the Shares
pursuant to the Stock Purchase Agreement, SAIC will own not less than eight
percent (8%) of the issued and outstanding Shares of Common Stock (including
treasury Shares and Shares reserved for issuance under existing stock options)
in the amount of 1,258,074 Shares;

       WHEREAS, the parties agree that SAIC should have the right to
participate in any future offerings of Common Stock by the Company so as to
avoid the dilution of SAIC's equity interest in the Company and that SAIC should
have the option to require the Company to purchase SAIC's Shares under certain
circumstances;

       WHEREAS, the parties agree that the Company should have the right to
purchase SAIC's Shares under certain circumstances;

       WHEREAS, the Company, SAIC and Carreker agree that SAIC should have at
least one representative as a member of the Board of Directors of the Company at
all times during the term of this Agreement;


                               Exhibit 5.07 - 1

<PAGE>

                               EXHIBIT 5.07

       WHEREAS, the parties believe that it is of mutual benefit to the
Company, to SAIC and to Carreker to provide for the nomination and election of
the representative of SAIC as a member of the Company's Board of Directors and
to provide for future dispositions of certain Shares;

       NOW, THEREFORE, in consideration of the foregoing and for other good and
valuable consideration, receipt of which is hereby acknowledged, the parties
hereto hereby agree as follows:


                                      ARTICLE 1
                                ELECTION OF DIRECTORS

       1.1   BOARD OF DIRECTORS.  The Company and Carreker hereby agree that
for so long as SAIC shall be entitled to have a representative on the Company's
Board of Directors pursuant to Section 1.2 below, neither the Company nor
Carreker shall take or permit to be taken any action which would increase the
size of the Board of Directors to more than twelve (12) members, except as set
forth in this Article 1.  In the event that the Board of Directors is increased
in size to more than twelve (12) members, the Company and Carreker hereby agree
to take all such action as shall be necessary to ensure that SAIC shall be
entitled to designate a number of directors to the Board equal to the product of
one-twelfth (1/12th) times (ii) the total number of directors on the Board after
the increase, rounded down to the nearest whole number.

       1.2   BOARD OF DIRECTORS REPRESENTATION.  The Company and Carreker agree
that SAIC shall have the right to have one (1) representative on the Company's
Board of Directors during the term of this Agreement.  Carreker hereby agrees to
vote for such SAIC nominated representative.  Accordingly, contemporaneous with
the Closing of the Stock Purchase Agreement (as defined therein), the Company
agrees to nominate, and Carreker agrees to elect, one representative to the
Company's Board of Directors designated by SAIC.  Following such election, the
members of the Board of Directors shall be those persons set forth on
EXHIBIT 1.2 hereto.  SAIC shall have the right to remove and replace its
representative at any time, in SAIC's sole discretion.

       1.3   AGREEMENT COUPLED WITH INTEREST.  The voting agreements set forth
in this Article 1 are coupled with an interest and may not be revoked without
the written consent of SAIC.

                               EXHIBIT 5.07


                                      ARTICLE 2
                       RIGHTS OF FIRST REFUSAL, PUTS AND CALLS

       2.1   SAIC RIGHT OF FIRST REFUSAL ON FUTURE SECURITIES.  Subject to the
terms and conditions specified in this Section 2.1, the Company hereby grants to
SAIC a right of first refusal with respect to future sales by the Company of its
Future Securities (as hereinafter defined).

             Each time the Company proposes to offer any Shares or options of,
       or securities convertible into or exercisable or exchangeable for, any
       class of its capital stock, including any Shares authorized by the
       Company in the future which will result in the Company having in excess
       of 1,258,074 Shares (including treasury Shares) issued and outstanding
       and reserved for issuance upon exercise of existing stock options
       ("FUTURE SECURITIES"), the Company shall first make an offering of such
       Future Securities to SAIC in accordance with the following provisions:

             (a)    The Company shall deliver a notice ("FUTURE SECURITIES
       NOTICE") to SAIC stating (i) its bona fide intention to offer or issue
       such Future Securities, (ii) the type and number of such Shares of
       Future Securities to be offered, (iii) the price for which it proposes
       to offer such Future Securities, and (iv) all other material terms and
       conditions relating to such Future Securities.

             (b)    Within 30 calendar days after SAIC's receipt of the Future
       Securities Notice, SAIC may elect to purchase, at the price and on the
       terms and conditions specified in the Future Securities Notice, up to
       that portion of such Shares of Future Securities which equals the
       proportion that the number of Shares of Common Stock then issued and
       held by SAIC bears to the total number of Shares of Common Stock of the
       Company issued and outstanding and reserved for issuance upon exercise
       of outstanding stock options.

             (c)    If all such Shares of Future Securities referred to in the
       Future Securities Notice are not elected to be purchased by SAIC as
       provided in subsection 2.1(b) hereof, the Company may, during the sixty
       (60) day period following the expiration of the period provided in
       subsection 2.1(b) hereof, offer the remaining unsubscribed Shares to any
       person or persons at a price not less than that, and upon terms and
       conditions no more favorable to the offeree than those, specified in the
       Future Securities Notice.  If the Company does not enter into an
       agreement for the sale of the Shares within such period, or if such
       agreement is not consummated within seventy-five (75) days of the
       execution thereof, the right provided hereunder shall be deemed to be
       revived and such Shares shall not be offered unless first reoffered to
       SAIC in accordance herewith.  Even though SAIC may decline to
       participate in an offering of Future Securities, the provisions of this
       Section 2.1 shall continue to apply to any subsequent offering of Future
       Securities and SAIC shall be eligible to purchase subsequently offered
       Future Securities on the same 


                               Exhibit 5.07 - 3

<PAGE>

                               EXHIBIT 5.07

       basis provided herein, except that the anti-dilution percentage will be
       reduced from eight percent (8%) to the SAIC percentage of ownership of
       Shares that results from the transaction in which SAIC did not 
       participate.

             (d)    With respect to any Shares that may be issued, from time to
       time, under stock options granted by the Company to its employees
       pursuant to stock option plans approved by the Company's Board of
       Directors, which result in the Company having in excess of 1,258,074
       Shares (including treasury Shares) issued and outstanding, SAIC shall
       have the right, at its option, to purchase such additional number of
       Shares of the same class of Common Stock from the Company at the price
       of the option(s) at the time the option is granted by the Company so as
       to enable SAIC to maintain the same percentage of ownership stake in the
       Company as it owned immediately preceding the date of grant of such
       options.

       2.2   SAIC'S STRATEGIC ALLIANCE PUT OPTION.  Subject to the terms and
conditions specified in this Section 2.2, the Company hereby grants to SAIC a
right to require that the Company purchase, and the Company hereby agrees to
purchase from SAIC, all of the Shares then issued and held by SAIC, including
any Shares acquired by SAIC pursuant to this Article 2 (the "STRATEGIC ALLIANCE
PUT OPTION").

             (a)    The Strategic Alliance Put Option is only exercisable if the
       cumulative revenues recognized by SAIC as a direct result of business
       done jointly by SAIC and the Company pursuant to the Strategic Alliance
       Agreement between SAIC and the Company of even date herewith do not
       exceed TWENTY-FIVE MILLION DOLLARS ($25,000,000) on or before the third
       (3rd) anniversary of this Agreement.  In the event this Agreement is
       terminated pursuant to Article 3 prior to the third (3rd) anniversary of
       this Agreement, the Strategic Alliance Put Option shall terminate.

             (b)    The price of the Shares under the Strategic Alliance Put
       Option shall equal the aggregate price paid by SAIC to acquire the
       Shares.

             (c)    To exercise the Strategic Alliance Put Option, on or before
       the last day of the fortieth (40th) month after the first date written
       above, SAIC shall provide Company with a written notice (the "STRATEGIC
       ALLIANCE PUT NOTICE") of SAIC's desire to have the Company purchase the
       Shares and, unless the provisions of subsection 2.2(d) apply, the
       Company shall pay SAIC in cash and SAIC shall transfer, assign and
       deliver the Shares, duly executed, to the Company on or before the
       thirtieth (30th) business day after Company receives the Strategic
       Alliance Put Notice.

             (d)    In the event Company's payment to SAIC pursuant to the
       Strategic Alliance Put Option would cause the Company to violate any of
       the covenants in Sections 5k, l, m, n or o (the "COMPASS BANK REVOLVER
       COVENANTS") of the $1 million revolving Line of Credit Loan from Compass
       Bank - Dallas to the Company dated October 26, 1995 (the 


                               Exhibit 5.07 - 4

<PAGE>

                               EXHIBIT 5.07

       "COMPASS BANK REVOLVER"), or which would violate the covenants of any
       future bank loan agreement (which such future covenants shall not be
       more restrictive, individually or collectively, than those contained
       in the Compass Bank Revolver in order to have the provisions of this 
       Section 2.2(d) to apply to any future bank loan agreement) so as to 
       prohibit borrowing by the Company under said agreement, Company may 
       elect to make and deliver a promissory note to SAIC substantially in 
       the form attached hereto as EXHIBIT 2.2(d) (the "PROMISSORY NOTE") 
       bearing an interest rate of the Prime Rate as defined hereafter plus 
       two percent (2%) with principal and interest payable semiannually over
       a period of three (3) years but with no prepayment penalty; FURTHER, 
       PROVIDED, HOWEVER, that if the making of any payment under the 
       Promissory Note at any time would cause Company to be in default of 
       the Compass Bank Revolver Covenants (or in default under any future 
       bank loan agreement as provided above), then Company may postpone 
       payments under the Promissory Note, until the aforementioned default 
       ceases but in no event shall the postponement of payment of principal
       and interest under the Promissory Note exceed five (5) years from the
       date of the Strategic Alliance Put Notice.  Interest will continue to
       accrue during any such postponement at the Prime Rate plus two percent
       (2%) per annum.  The "PRIME RATE" shall mean the fluctuating per annum
       interest rate established by NationsBank, N.A. in Dallas, Texas, as its
       prime rate of interest offered from time to time.  SAIC shall retain all
       Shares until payment in full of the Promissory Note is made by Company.
       In addition to the foregoing, during the period of any postponement of 
       payment of principal and interest by the Company to SAIC pursuant to the
       Strategic Alliance Put Option, during such postponement, no base salary,
       bonuses, awards or other payment for services rendered by Carreker to 
       the Company shall be made if such payment to Carreker would render the 
       Company insolvent or otherwise unable to pay its debts as they become 
       due.

       2.3   SAIC'S CARREKER SHARES PUT OPTION.  Subject to the terms and
conditions specified in this Section 2.3, the Company hereby grants to SAIC a
right to require that the Company purchase any or all of the Shares owned by
SAIC, including any Shares acquired by SAIC pursuant to this Article 2 (the
"CARREKER SHARES PUT OPTION").

             (a)    Carreker may sell, assign, transfer, alienate, convey,
       donate or otherwise in any manner dispose of (such dispositions are
       hereafter collectively referred to as a "TRANSFER") his Carreker Shares
       by a bona fide sale to a third party, provided that Carreker has first
       complied with the procedures set forth in this Section 2.3.  In the
       event Carreker, at any time, intends to Transfer to a third party an
       amount of Carreker Shares that would, at any time, result in such third
       party owning more Shares than SAIC, Carreker agrees to and shall deliver
       to SAIC (with a copy to the Company) notice of such intention by
       delivering a signed written statement setting forth Carreker's desire to
       Transfer all or a portion of the Carreker Shares, the number of Carreker
       Shares to be Transferred, the identity of the proposed Transferee, the
       proposed Transfer price and all other material terms and conditions
       relating to the proposed Transfer ("CARREKER'S NOTICE OF INTENTION TO
       TRANSFER").  The following shall not be considered a "third party" and
       this Section 2.3 


                               Exhibit 5.07 - 5

<PAGE>

                               EXHIBIT 5.07

       shall not apply to Transfers to (i) the Company; (ii) to Carreker's 
       immediate family (spouse, children, parents or siblings of Carreker) 
       or to a trust for the benefit of Carreker or his immediate family; or
       (iii) to a corporation, all of whose capital stock is owned by Carreker.

             (b)    Within thirty (30) days after SAIC's receipt of Carreker's
       Notice of Intention to Transfer, SAIC may, at its option, elect to
       exercise the Carreker Shares Put Option by providing the Company (with a
       copy to Carreker) with a written notice (the "SAIC CARREKER SHARE PUT
       OPTION NOTICE") of SAIC's desire to have the Company purchase or all of
       any SAIC's Shares.

             (c)    The price for Shares under the Carreker Shares Put Option
       shall be the highest of (i) the then fair market value of the Shares or
       (ii) the price paid by SAIC to acquire SAIC's Shares or (iii) the price
       at which Carreker Proposes to Transfer the Carreker Shares.

             (d)    The Company shall pay SAIC in cash and SAIC shall transfer,
       assign and deliver the Shares, duly executed, to the Company on or
       before the thirtieth (30th) business day after the Company receives the
       Carreker Share Put Option Notice.

             (e)    This Carreker Shares Put Option shall apply to each and
       every Transfer of Carreker Shares during the term of this Agreement.

       2.4   COMPANY'S RIGHT OF FIRST REFUSAL ON SAIC'S SHARES.  Subject to the
terms and conditions of this Section 2.4 and during the term of this Agreement,
SAIC hereby grants to the Company a right of first refusal with respect to any
Shares that SAIC proposes to sell to a third party (excluding thereby, from the

       that in the event the Company sells any Shares of its Common Stock
       (other than Shares issued upon exercise of outstanding employee stock
       options) to any other person or entity within twelve (12) months
       following the date of the Company's payment to SAIC under the Call
       Option at a per Share price in excess of the price paid per Share to

       sold under the Call Option up to the number of Shares sold to the other
       person or entity.

             (c)    To exercise the Call Option, on or before the last day of
       the fortieth (40th) month after the first date written above, the

SUBSTANTIATION:

       In order for Maker to be entitled to or exercise any postponement
       under this Promissory Note, Maker must first provide Payee with

the Maker or any subsequent holder shall be adverse parties, the Maker waives 
the right to interpose any defense, set-off, or counterclaim other than 
payment in accordance with the terms hereof.

The holder's acceptance of any installment or payment after it of the full 
amount thereof may have become due and payable hereunder shall not be deemed 
to alter the holder's rights or Maker's obligations with respect to any 
subsequent payments or defaults hereunder.

The Maker shall have the right to prepay the principal amount outstanding, in 
whole or in part, together with any accrued interest thereon, without 
penalty. Any partial prepayment shall be first applied against any interest

judicial proceeding, then Maker shall pay Payee reasonable attorneys fees and 
court costs, in addition to other amounts due.  Reasonable attorney's fees

under the laws of the State of Texas, and is duly qualified to do business 
and is in good standing as a foreign corporation in all other jurisdictions 
where Seller owns or leases property or where the nature of Seller's business

properties, to carry on its business and to hold under lease the properties 
it holds under lease.  Seller has full power and authority to enter into this 
Agreement and to perform the transactions contemplated hereby.  Accurate and

necessary for the authorization, execution, delivery and performance by 
Seller of this Agreement and the consummation of the transactions 
contemplated hereby will have been taken.  This Agreement is a legal, valid 
and binding obligation of Seller and enforceable against Seller in accordance

remedies.

          (d)  VALID ISSUANCE OF CAPITAL STOCK.

               (i)    The Shares, when issued, sold and delivered in 
accordance with the provisions of this Agreement, for the consideration 
expressed herein, will be duly and validly issued, fully paid and 
non-assessable and, assuming the accuracy of the representation and warranty 
of Buyer set forth in Section 4(d), will be issued in compliance with all 
applicable federal and state securities laws.  The Shares, when sold and 
delivered to Buyer in accordance with the provisions of this Agreement, will 
not have been issued in violation of any contractual or statutory preemptive 
rights.

               (ii)   The outstanding shares of Common Stock of Seller have 
been duly and validly authorized, issued and delivered, and are validly

Antinori Software, Inc., as disclosed on Schedule 3(b), the ownership of the 
capital stock of the Company shall be as listed on Schedule 3(d).

          (e)  TITLE TO AND CONDITION OF ASSETS.  Seller has good and 
marketable title to all property reflected on the Balance Sheet (as 
hereinafter defined) (except property sold or otherwise disposed of in the 
ordinary course of business after November 30, 1996), free and clear of all 
mortgages, liens, security interests, pledges, charges, claims, encumbrances 
and restrictions of any nature whatsoever, except as described on Schedule 
3(e).  All tangible assets (whether owned or leased) utilized by Seller in 
its business are in good operating condition and repair, subject to normal 
wear and tear.  Seller has good and marketable title to all of the assets 
necessary to conduct its business as presently conducted or as proposed to be 
conducted.

          (f)  NO INVESTMENTS.  Except as set forth in Schedule 3(f), the 
Company does not own or control, directly or indirectly, any capital stock or 
other equity, debt, ownership or proprietary interest in any corporation, 
partnership, association, trust, joint venture or other entity.

          (g)  FINANCIAL STATEMENTS.  Copies of the balance sheet of Seller 
as of November 30, 1996 (the "Balance Sheet"), the related statement of 
income for the 10 months then ended, and Seller's audited financial 
statements as of and for the years ending January 31, 1996 and January 31, 
1995 (collectively, the "Financial Statements"), have been delivered to 
Buyer.  The Financial Statements have been prepared in conformity with 
generally accepted accounting principles ("GAAP") applied on a basis 
consistent with prior periods, except as may be otherwise expressly 
indicated, and present fairly the financial condition of Seller as of the 
dates and the results of operations of Seller for the periods indicated.

          (h)  LIABILITIES.  Seller has no material liabilities or 
obligations of any nature, whether absolute, accrued, contingent or otherwise 
and whether due or to become due, that are not reflected on the Balance Sheet 
or in the notes thereto, except for liabilities incurred since such date in 
the ordinary course of business.

          (i)  PROPRIETARY RIGHTS.  Seller owns or has the unrestricted right 
to use all proprietary rights (including patents, trademarks, service marks, 
tradenames, software and applications therefor or licenses thereto) used in 
its business.  To the best of Seller's knowledge, all such proprietary rights 
are in good standing and uncontested and do not violate or infringe on the 
proprietary rights of any third party.  To the best of Seller's knowledge, 
there is no claim, action, proceeding or investigation pending or threatened 
against Seller with respect to any of such proprietary rights.  Seller has no 
knowledge that any third party is infringing any of such proprietary rights.

                                       -3-

<PAGE>

          (j)  TAXES.  Seller has filed all tax reports and returns 
(including, without limitation, all federal, state and local income tax, 
franchise tax, gross receipts, sales tax, and real and personal property tax 
returns) required to be filed and has either paid all taxes and other charges 
indicated due on the basis of such returns and reports, or has made adequate 
provision for the payment thereof, and the assessment of any material amount 
of additional taxes in excess of those paid and reported is not reasonably 
expected.  Seller has withheld all taxes required to be withheld by it or by 
any federal, state, local or foreign taxing authority.  There are no claims 
asserted for, or, to the best of Seller's knowledge, pending questions of a 
material nature relating to, taxes or assessments against Seller.  The 
reserves for taxes reflected on the Balance Sheet are adequate in amount for 
the payment of all liabilities for all taxes (whether or not disputed) of 
Seller accrued through the date of such Balance Sheet.

          (k)  CONTRACTS.  Except as set forth on Schedule 3(k), to the best 
of Seller's knowledge, all material contracts and leases and other agreements 
to which Seller is a party or by which it or its assets are bound are valid 
and in full force and effect.  Except as set forth on Schedule 3(k), Seller 
is not in default, and has not been notified by any other party that it is in 
default, under any material contract, lease or agreement, and no party with 
whom Seller has an agreement which is of material importance to Seller is in 
default thereunder.

          (l)  LITIGATION.  There are no actions, suits, proceedings and 
investigations pending or, to the best of Seller's knowledge, threatened 
against or affecting Seller, or any property or right of Seller.  Seller is 
not aware of any fact which would provide a valid basis for any 
investigation, action, suit, proceeding or claim which could, either alone or 
in the aggregate, materially and adversely affect the condition (financial or 
otherwise) of Seller.

          (m)  COMPLIANCE WITH LAWS.  Seller is not in default in any respect 
under any law, ordinance, requirement, regulation, rule or order applicable 
to its business the violation of which might materially and adversely affect 
Seller.  Seller is not subject to any continuing court or administrative 
order, writ, injunction or decree applicable specifically to it or to its 
business, property or employees, and is not in default with respect to any 
order, writ, injunction or decree of any court or federal, state, municipal 
or other governmental department, commission, board, agency or 
instrumentality, domestic or foreign, to such an extent that any default 
would or could have a materially adverse effect on the condition (financial 
or otherwise) of Seller.

          (n)  ABSENCE OF CONFLICTS.  Neither the execution and delivery of 
this Agreement nor the consummation of the transactions provided for herein 
or the fulfillment by Seller of the terms hereof will (a) conflict with or 
result in a breach of any provision of Seller's Articles of Incorporation or 
By-laws, 

                                       -4-

(b) result in a conflict or default or give rise to any right of termination, 
cancellation or acceleration under any of the terms, conditions or provisions 
of any note, bond, mortgage, indenture, license, agreement or other 
instrument or obligation to which Seller is a party or by which Seller is 
bound, (c) violate any order, writ, injunction, decree, statute, rule or 
regulation applicable to Seller or any of the material properties or assets 
of Seller or (d) terminate or adversely affect any material permit, license 
or authorization of any governmental authorities used or required by Seller.

          (o)  GOVERNMENTAL CONSENTS AND REGULATIONS.  No consent, approval 
or other action by any local, state, federal or foreign governmental 
authority is required in connection with the execution and delivery by Seller 
of this Agreement and the consummation of the transactions contemplated 
hereby.

          (p)  LICENSES AND PERMITS.  Seller has all licenses, permits and 
other authorizations of governmental authorities, domestic and foreign, 
necessary in the conduct of its business.  Seller has not received any notice 
(nor, to the best of Seller's knowledge, does Seller have any reason to 
believe) that revocation is being considered with respect to any of such 
licenses, permits or authorizations.

          (q)  OFFERING.  Assuming the accuracy of the representations of 
Buyer set forth in Section 4(d), the offer and sale of the Shares are exempt 
from the registration requirements of the Securities Act of 1933, as amended 
(the "Securities Act"), and the Texas securities laws.

          (r)  NO MATERIAL ADVERSE CHANGE.  Since November 30, 1996, there 
has not been any material adverse change in the condition (financial or 
otherwise) of Seller.

other agreements delivered hereunder are valid and binding agreements of 
Buyer enforceable against Buyer in accordance with their terms, except as

transactions contemplated by this Agreement.

          (d)  INVESTMENT.  Buyer is acquiring the Shares solely for its own

          (a)  If Buyer proposes to sell, pledge, exchange or otherwise 
dispose of any of its Shares, whether for cash or other consideration, Buyer 
shall promptly deliver to the Secretary of Seller a written notice 
(hereinafter referred to as the "Notice").  Such Notice shall include a true 
and complete copy of a written bona fide offer for the purchase or transfer 
of Buyer's Shares, the name and address of the proposed purchaser or 
transferee and the proposed purchase price, terms, and conditions of the 
transfer, which must include a sufficient period prior to consummation of 
such purchase or transfer for the option period contemplated by subsection 
(b) below to expire (the "Bona Fide Offer").

          (b)  Seller shall have an option to purchase all, and not less than 
all, of the Shares of Buyer subject to the Bona Fide Offer at the same price 
and upon substantially the same terms and conditions as set forth in the Bona

days after receipt of the Notice.

          (c)  Upon the refusal or failure of Seller to exercise its option 
to purchase the Shares in accordance with subsection (b) above, such Shares 
may be sold upon the terms and conditions set forth in the Bona Fide Offer, 
provided that the notice of the closing thereunder shall be given to Seller

                                       -7-

<PAGE>

condition precedent to such purchase, agree to be bound by all terms and 
provisions of this Section 8.

          (d)  The right of first refusal granted to Seller hereunder shall 
not apply to any transfer of Shares by Buyer to any Affiliate of Buyer.  For 
purposes of this Section 8, an "Affiliate of Buyer" shall mean any person, 
corporation, partnership or other entity which controls Buyer or is 
controlled by Buyer or is under common control of or with Buyer; provided, 
however, any Affiliate of Buyer shall continue to be subject to the right of 
first refusal granted Seller under this Section 8.

          (e)  The right of first refusal granted to Seller under this 
Section 8 shall automatically terminate upon the occurrence of any of the 
following events:

               (i)    The bankruptcy or insolvency of Seller;

               (ii)   The closing of a public offering of securities of 
Seller pursuant to a registration statement declared effective under the 
Securities Act of 1933, as amended; or

               (iii)  The closing of the sale of all or substantially all of 
the assets of Seller, the consolidation or merger of Seller in which Seller 
is not the surviving corporation, or the complete liquidation of Seller in 
compliance with the Texas Business Corporation Act.

     9.   RIGHT OF INCLUSION.  Seller represents to Buyer that as of the date 
of this Agreement Seller has not granted to any party rights to require 
Seller to register under the Securities Act of 1933, as amended (the "Act"), 
securities issued by Seller ("registration rights").  Buyer acknowledges that 
the contemplated transaction with Antinori Software, Inc., as disclosed on 
Schedule 3(b), likely will involve the grant of registration rights to one or 
more of the former shareholders of Antinori Software, Inc.

     Seller hereby grants Buyer the right to have included, in each 
registration under the Act of common stock (of any class) of Seller resulting 
from the exercise of contractual registration rights granted to such former 
shareholders, or to any other party, Buyer's proportionate share of such 
common stock; provided, however, that in order to exercise the foregoing 
right Buyer must first agree in writing to abide by all terms and conditions 
of such contractual registration rights regarding the inclusion of shares in 
such registration, so that to the greatest extent practical Buyer's foregoing 
right of inclusion is PARI PASSU with, but not superior or subordinate to, 
provisions regarding the inclusion of shares in the exercise of such 
contractual registration rights.  Without limiting the foregoing, such terms 
and conditions may include provisions regarding Buyer's agreement to enter 
into an underwriting agreement in respect of any underwritten offering of 
Buyer's shares, indemnify the underwriters thereof, accept the 

                                       -8-

<PAGE>

exclusion of shares previously proposed to be included in any such 
registration based on an underwriter's or underwriters' opinion that the 
initially proposed number of shares to be included will adversely affect the 
success of the offering thereof (i.e., "underwriters' cutbacks"), and any and 
all other terms and conditions, whether or not customary, obligating 
participants in any such registration (e.g., "lock-up" provisions, provisions 
regarding payment of the expenses of registration, and market "standoff" and 
"blackout" provisions, etc.).  Notwithstanding anything to the contrary in 
this Agreement, (a) in no event shall this Section 9 be construed to grant 
Buyer the right to unilaterally exercise "demand," "piggyback" or other 
registration rights and (b) the foregoing right of inclusion shall expire as 
to any shares of common stock issued by Seller when such shares are eligible 
for sale under Rule 144 promulgated under the Act.

     For purposes of this Section 9, Buyer's "proportionate share" shall be 
the number of shares of Seller's common stock (of any class) then held by 
Buyer multiplied by a fraction, the numerator of which is the total number 
shares of such common stock proposed to then be registered under the Act and 
the denominator is the number of shares of such common stock then issued and 
outstanding or otherwise contractually subject to issuance (i.e., calculated 
on a fully-diluted basis).

     10.  MISCELLANEOUS.

          (a)  ENTIRE AGREEMENT; CONSTRUCTION.  This Agreement constitutes 
the entire agreement between Buyer and Seller and supersedes any prior 
understandings or agreements, written or oral, that relate to the subject 
matter hereof.  All representations, warranties and covenants of Buyer and 
Seller contained herein or in any document delivered hereunder shall survive 
the Closing and remain in full force and effect thereafter; provided, 
however, that Seller's representations and warranties set forth in 
subsections (e) through (r) , inclusive, of Section 3 shall survive the 
Closing and thereafter remain in full force and effect only until the second 
anniversary of the Closing.

     This Agreement may not be amended except in writing signed by both Buyer 
and Seller.

          (b)  EXPENSES.  The parties agree that all fees and expenses

     TRAVEL

The date of the trip, destination and client or purpose of the trip must be 
clearly stated.  Meals charged to the client should NOT EXCEED $35.00 per day 
for each person assigned to a project.  Meal expenses are reported as actual 
amounts, to a per diem allowance.

Drinks or wine as part of the meal allowance may be charged to the client, 
however, personal entertainment "clubbing" is not to be charged.

Business entertainment must be specifically authorized by the appropriate 
Project Manager.  All entertainment must be documented to include name, 
description of activity, and the nature of the business discussion.

Personal entertainment (including in-room movies) should not be charged to 
the client,

Laundry and valet services are not billable to the client unless the 
assignment involves more than five (5) consecutive days.

Telephone calls must be identified and billed appropriately.  Telephone 
charges are determined by the subject or project being discussed, not the 
location from which the call is made.  Individual telephone bills are 
distributed for identification of charges and are expected to be returned to 
the accounting department promptly.  Calls ARE NOT TO BE MADE FROM AIRPHONES.

Efforts should be made to control expenses in your choice of hotels and 
restaurants.  Use hotels that allow the client a corporate rate whenever 
possible.  Charges on hotel bills must be itemized.

The most reasonable type of transportation must be chosen. Generally taxi 
rides are cheaper than rental cars.  Try to plan plane routes and schedules 
that avoid excess charges.

<PAGE>

Rental cars should be charged on Diner's Club to take advantage of the 
insurance they provide.  If this is not possible, be sure to take out the 
rental car insurance.

An employee working out-of-town may elect to remain on site or travel to a 
destination other than the home office over the weekend.  However, additional 
charges incurred for transportation, laundry, or meals are to be paid by the 
individual.

Upgrades or first class tickets are not to be used.

Mileage may be charged at $.29 per mile.  Please use the following CARREKER 
ANTINORI standards:

     Office to Hartsfield Airport    --      15 Miles


     A contractor traveling from his/her home (instead of the office) to one of
     these destinations should use these standards.

Expenses OVER $25.00 MUST be supported with receipts.  For billing, purposes 
it is important to try to document all expenses, regardless of the amount.

ALL travel arrangements will be made through the company authorized travel 
agent.

     OTHER BILLABLE EXPENSES

All non-travel expenses are reviewed by the Project Manager.  The Project 
Manager must give prior approval to all purchases that will be billed to the 
client.

Production expenses are billed as follows:

NON-BILLABLE EXPENSES

     TRAVEL/MARKETING

Expenses relating to marketing must be approved by the Practice Director or 
Sales Manager and must conform to a planned budget.  The basic guidelines for 
billable travel will apply for sales travel as well.

All marketing related entertainment must be documented to include client 
name, date, description of activity, and the nature of the business 
discussion.

CARREKER-ANTINORI expects employees to call the office twice a day when they 
are traveling and allows a daily telephone call home. Marketing calls are 
charged to the individual's practice.  Calls are not to be made from 
airphones.

OTHER EXPENSES

Purchase requisitions are required for all non-travel purchases. The 
requisitions must be signed by your Practice Director and must accompany all 
purchases listed on an expense report or submitted to the Accounting 
Department for payment.  Purchases over $1,000 also require the approval of 
the Chief Financial Officer.

Responsibility for planning has been assigned for the following areas:

                              INVOICE PROCEDURES

Listed below are the guidelines you should follow when submitting an invoice 
to CARREKER ANTINORI.

TIME SHEETS

Time sheets are to be submitted twice monthly, on the 15th and the end of the 
month.  Billing periods are from the 1st through the 15th, and the 16th 
through the end of the month.  Time sheets can be faxed to Accounting; 
however, the original must be sent to Accounting as soon as possible.  The 
correct time period, including month, day and year, should be indicated and 
the time sheet must be signed by the contractor and initialed by the 
appropriate supervisor. Use the correct project number and record the hours 
worked each day on the project.  Non-billable time is recorded with a project 
number which indicates the department for which work is being done.  Record 
only the time that you have been authorized by your supervisor to bill.  
Invoices for labor must be concurrent with the time period and be for the 
same number of hours on the time sheet.  They should be in a format which 
provides the name and address of the contractor, the number of hours worked, 
the project number(s), the rate being charged, and the total due.  Invoices 
must be approved by the project supervisor before payment can be made.

EXPENSE REPORTS

Expense reports should be submitted using QuickXpense software.  Expenses are 
to be submitted once a month, on the 25th.  Do not submit more than one 
expense report per month.  Project numbers to be billed should be clearly 
indicated; nonbillable expenses must be designated as Admin or Marketing, and 
the appropriate department indicated.  Airline tickets purchased by the, 
company must be included on the report in the column headed "Paid By 
Company."  The face of the report can be faxed to Accounting; however, the 
original and all necessary receipts must be in Accounting before 
reimbursement can be made. Submit a separate invoice that corresponds to the 
expense report and have it approved by your supervisor.  Expense checks are 
issued on the 15th of the month following the 25th submission date.

The Accounting fax number is 404-873-5554.

Please see CARREKER ANTINORI's Controller if you have any questions or would
like additional information.

                 NOW, THEREFORE, in consideration of the foregoing and the 
mutual agreements of Carreker, Antinori and Newco contained herein, the 
parties agree as follows:

          1.     PLAN OF MERGER

                 1.1     THE MERGER.  The Plan of Merger will be filed with 
the Secretaries of State of the States of Texas and Georgia as soon as 
practicable after the Closing (as defined in Section 6.1; hereinafter the 
"CLOSING").  The effective time of the Merger as specified in the Plan of 
Merger (the "EFFECTIVE TIME") will occur on or before January 31, 1997 or on 
such other date as the parties may mutually agree upon.  Subject to the terms 
and conditions of this Agreement and the Plan of Merger, Newco will be merged 
with and into Antinori pursuant to the Plan of Merger and in accordance with 
applicable provisions of the laws of the States of Texas and Georgia as 
follows:

                         1.1.1     CONVERSION OF SHARES.  The shares of 
Antinori Common Stock, $.01 par value per share (the "ANTINORI COMMON 
STOCK"), that are issued and outstanding immediately prior to the Effective 
Time will by virtue of the Merger and at the Effective Time, and without 
further action on the part of any holder thereof, be converted into the 
Applicable Number of fully paid and nonassessable shares of Carreker Class A 
Voting Common Stock, no par value per share (the "CARREKER CLASS A COMMON 
STOCK").  Unless there is an adjustment to the shares to be issued in the 
Merger pursuant to Section 1.1.2 below, the "APPLICABLE NUMBER" will equal 
(a) 0.50946871 multiplied by (b) the total number of shares of Antinori 
Common Stock issued and outstanding at the Effective Time. The shares to be 
issued and the recipients thereof are identified on EXHIBIT 1.1.1.

                         1.1.2     ADJUSTMENTS FOR CAPITAL CHANGES.  If prior 
to the Merger, Carreker recapitalizes either through a split-up of its 
outstanding shares into a greater number, or through a combination of its 
outstanding shares into a lesser number, or reorganizes, reclassifies or 
otherwise changes its outstanding shares into the same or a different number 
of shares of other classes (other than through a split-up or combination of 
shares provided for in the previous clause), or declares a dividend on its 
outstanding shares payable in shares or securities convertible into shares, 
the number of shares of Carreker Class A Common Stock into which the shares 
of Antinori Common Stock are to be converted will be adjusted appropriately.

AGREEMENT AND PLAN OF MERGER - Page 2
<PAGE>

                         1.1.3     ANTINORI TREASURY STOCK.  All shares of 
Antinori Common Stock that are held by Antinori as treasury stock shall be 
cancelled and retired and no shares of Carreker Common Stock, of Class A 
Voting or Class B Non-Voting (collectively, "CARREKER COMMON STOCK"), shall 
be delivered or paid in exchange therefor.

                 1.2     FRACTIONAL SHARES.  No fractional shares of Carreker 
Class A Common Stock will be issued in connection with the Merger, but in 
lieu thereof, the holder of any shares of Antinori Common Stock who would 
otherwise be entitled to receive a fraction of a share of Carreker Class A 
Common Stock would receive from Carreker, promptly after the Effective Time, 
an amount of cash equal to $23.83 multiplied by the fraction of a share of 
Carreker Class A Common Stock to which such holder would otherwise be 
entitled.

                 1.3     ESCROW AGREEMENTS.  Pursuant to the Escrow Agreement 
in the form of EXHIBIT D-1 (the "ANTINORI ESCROW AGREEMENT"), Carreker will 
withhold from the shares of Carreker Class A Common Stock that would 
otherwise be delivered to the Antinori Shareholders, 25,700 shares of 
Carreker Class A Common Stock, being approximately (and less than) 5% of the 
total number of shares of Carreker Class A Common Stock issuable to such 
shareholders in the Merger.  On the Closing Date, Carreker will deposit or 
cause to be deposited in escrow pursuant to the Antinori Escrow Agreement 
certificates representing the shares thus withheld (the "ANTINORI ESCROW 
SHARES") as collateral for the indemnification obligations of the Antinori 
Shareholders under Section 10.2, pending their release from escrow pursuant 
to the Antinori Escrow Agreement.

          Also on the Closing Date, Carreker will deposit or cause to be 
deposited in escrow pursuant to the Carreker Escrow Agreement certificates 
representing 25,700 shares of Carreker Class A Common Stock (the "CARREKER 
ESCROW SHARES").  The Carreker Escrow Shares will be held as collateral for 
the indemnification obligations of the Carreker Principal Shareholders under 
Section 11.2, and pursuant to the Escrow Agreement in the form of EXHIBIT D-2 
(the "CARREKER ESCROW AGREEMENT"), pending their release from escrow pursuant 
to the Carreker Escrow Agreement.

                 1.4     EFFECTS OF THE MERGER.  At the Effective Time: (a) 
the separate existence of Newco will cease and Newco will be merged with and 
into Antinori and Antinori will be the surviving corporation pursuant to the 
terms of the Plan of Merger, (b) the Articles of Incorporation and Bylaws of 
Antinori will continue unchanged as the Articles of Incorporation and Bylaws 
of the surviving corporation, (c) each share of Newco Common Stock 
outstanding immediately prior to the Effective Time will continue to be an 
identical outstanding share of the surviving corporation, (d) the composition 
of the Board of Directors of Antinori shall be as set forth in ANNEX 1 to 
EXHIBIT A, (e) the officers of Antinori shall be the persons set forth in 
ANNEX 1 to EXHIBIT A and (f) the Merger will, at and after the Effective 
Time, have all of the effects provided by applicable law.

                 1.5     FURTHER ASSURANCES.  Antinori agrees that if, at any 
time after the Effective Time, Carreker considers or is advised that any 
further deeds, assignments or assurances are reasonably necessary or 
desirable to vest, perfect or confirm in the surviving corporation title to 
any property or rights of Antinori, Carreker and any of its officers are 
hereby authorized by 

AGREEMENT AND PLAN OF MERGER - Page 3
<PAGE>

Antinori to execute and deliver all such proper deeds, assignments and 
assurances and do all other things necessary or desirable to vest, perfect or 
confirm title to such property or rights in the surviving corporation and 
otherwise to carry out the purposes of this Agreement, in the name of 
Antinori or otherwise.

                 1.6     TAX-FREE REORGANIZATION.  The parties intend to 
adopt this Agreement as a tax-free plan of reorganization and to consummate 
the Merger in accordance with the provisions of Section 368(a)(1)(A) and 
368(a)(2)(E) of the Code.  The shares of Carreker Class A Common Stock issued 
in the Merger will be issued solely in exchange for the issued and 
outstanding shares of Antinori Common Stock pursuant to this Agreement, and 
no other transaction other than the Merger represents, provides for or is 
intended to be an adjustment to the consideration paid for the Antinori 
Common Stock.  Except for cash paid in lieu of fractional shares, no 
consideration that could constitute "other property" within the meaning of 
Section 356 of the Code will be paid by Carreker for shares of Antinori 
Common Stock in the Merger.  In addition, Carreker represents that it 
presently intends, and that at the Effective Time it will intend, to continue 
Antinori's historic business or use a significant portion of Antinori's 
business assets in a business.  At the Closing, officers of Carreker and 
officers of Antinori will execute and deliver officers' certificates in the 
forms of EXHIBITS E-1 AND E-2.

                 1.7     POOLING OF INTERESTS.  The parties intend that the 
Merger be treated as a "pooling of interests" for accounting purposes.

          2.     REPRESENTATIONS AND WARRANTIES OF ANTINORI

                 Antinori hereby represents and warrants that, except as set

material adverse effect on Antinori, its assets or properties or its 
financial condition.

                 2.2     POWER, AUTHORIZATION AND VALIDITY.

                         2.2.1     Antinori has the corporate right, power,

binding obligations of Antinori, enforceable against Antinori in accordance 
with their respective terms, except as to the effect, if any of (a) 
applicable bankruptcy and other similar laws affecting the rights of 
creditors generally, and (b) rules of law governing specific performance, 
injunctive relief and other equitable remedies; provided, however, that the

stock, and there is no liability for dividends accrued but unpaid; and there 
are no voting agreements, rights of first refusal or other restrictions

AGREEMENT AND PLAN OF MERGER - Page 5
<PAGE>

                 2.5     NO VIOLATION OF EXISTING AGREEMENTS.  Neither the 
execution and delivery of this Agreement or any Antinori Ancillary Agreement, 
nor the consummation of the transactions provided for herein or therein, will 
conflict with, or (with or without notice or lapse of time, or both) result 
in a termination, breach, impairment or violation of, (a) any provision of 
the Articles of Incorporation or Bylaws of Antinori, as currently in effect, 
(b) to the knowledge of Antinori, any material instrument or contract to 
which Antinori is a party or by which Antinori is bound, or (c) any federal, 
state, local or foreign judgment, writ, decree, order, statute, rule or 
regulation applicable to and that would have a material adverse effect on 
Antinori or its assets or properties.  The consummation of the Merger by 
Antinori and succession by Carreker to all rights, licenses, franchises, 
leases and agreements of Antinori will not require the consent of any third 
party and will not have a material adverse effect upon any such rights, 
licenses, franchises, leases or agreements pursuant to the terms of those 
agreements, other than as set forth in SCHEDULE 2.5.

                 2.6     LITIGATION.  Except as set forth in SCHEDULE 2.6, 
there is no action, proceeding or investigation pending or, to Antinori's 
knowledge, threatened against Antinori before any court or administrative 
agency that, if determined adversely to Antinori, may reasonably be expected 
to have a material adverse effect on the present or future operations or 
financial condition of Antinori or in which the adverse party or parties seek 
to recover in excess of $25,000 against Antinori.  Except as set forth on 
SCHEDULE 2.6, there is no substantial basis for any person, firm, corporation 
or entity to assert a claim against Antinori or Carreker as successor in 
interest to Antinori based upon: (a) ownership or rights to ownership of any 
shares of Antinori Common Stock, (b) any rights as a Antinori securities 
holder, including, without limitation, any option or other right to acquire 
any Antinori securities, any preemptive rights or any rights to notice or to 
vote, or (c) any rights under any agreement between Antinori and any Antinori 
securities holder or former Antinori securities holder in such holder's 
capacity as such. 

                 2.7     ANTINORI FINANCIAL STATEMENTS.  Antinori has 
delivered to Carreker the financial statements as set forth in SCHEDULE 2.7 
(the "ANTINORI FINANCIAL STATEMENTS").  The Antinori Financial Statements 
have been prepared on an accrual basis and, in all material respects, (a) are 
in accordance with the books and records of Antinori, (b) fairly and 
accurately represent the financial condition of Antinori at the respective 
dates specified therein and the results of operations for the respective 
periods specified therein in both cases in conformity with generally accepted 
accounting principles, and (c) have been prepared in accordance with 
generally accepted accounting principles applied on a consistent basis.  
Except as set forth in SCHEDULE 2.7, to the knowledge of Antinori, Antinori 
has no material debt, liability or obligation of any nature, whether accrued, 
absolute, contingent or otherwise, and whether due or to become due, that is 
not reflected, reserved against or disclosed in the Antinori Financial 
Statements, except for (i) those that are not required to be reported in 
accordance with such accounting principles and (ii) those that may have been 
incurred after the issuance of the unaudited balance sheet of Antinori on 
December 31, 1996 (the "BALANCE SHEET DATE") in the ordinary course of its 
business.

          Financial statements of Antinori as of December 31, 1995, December 
31, 1994 and December 31, 1993 and for the years then ended, in each case 
meeting the requirements of Regulation S-X promulgated by the Securities and 
Exchange Commission, can be readily prepared 

AGREEMENT AND PLAN OF MERGER - Page 6
<PAGE>

from Antinori's financial statements as of such dates and for such years and 
from other readily available information.

                 2.8     TAXES.  Except as set forth in SCHEDULE 2.8, to the 
knowledge of Antinori, Antinori has filed all federal, state, local and 
foreign tax and information returns required to be filed, has paid all taxes 
required to be paid in respect of all periods for which returns have been 
filed, has made all necessary estimated tax payments, and has no material 
liability for taxes in excess of the amount so paid.  True, correct and 
complete copies of all such tax and information returns have been provided or 
made available by Antinori to Carreker.  Except as set forth on SCHEDULE 2.8, 
to the knowledge of Antinori, Antinori is not delinquent in the payment of 
any tax or in the filing of any tax returns, and no deficiencies for any tax 
have been threatened, claimed, proposed or assessed which have not been 
settled or paid.  Except as set forth in SCHEDULE 2.8, no tax return of 
Antinori has ever been audited by the Internal Revenue Service or any state 
taxing agency or authority.  For the purposes of this Section 2.8, the terms 
"TAX" and "TAXES" include all federal, state, local and foreign income, 
gains, franchise, excise, property, sales, use, employment, license, payroll, 
occupation, recording, value added or transfer taxes, governmental charges, 
fees, levies or assessments (whether payable directly or by withholding), 
and, with respect to such taxes, any estimated tax, interest and penalties or 
additions to tax and interest on such penalties and additions to tax.

          Without limiting the foregoing, Antinori's election for treatment 
as a sub-chapter "S" corporation was valid and proper at the time of such 
election, has not been revoked and will continue to be valid and proper 
through the Effective Time.

                 2.9     TITLE TO PROPERTIES.  Antinori has good and 
marketable title to all of its assets as shown on the balance sheet as of the 
Balance Sheet Date included in the Antinori Financial Statements, free and 
clear of all liens, charges or encumbrances (other than for taxes not yet due 
and payable and Permitted Liens (as defined below)), other than such material 
assets set forth on SCHEDULE 2.9 as were sold by Antinori in the ordinary 
course of business since the Balance Sheet Date or which are subject to 
capitalized leases. "PERMITTED LIENS" means any lien, mortgage, encumbrance 
or restriction that is reflected in the Antinori Financial Statements and is 
not in excess of $100,000 and which does not materially detract from the 
value or materially interfere with the use, as currently used, of the 
properties subject thereto or affected thereby or otherwise materially impair 
the business operations  being conducted thereon.  There are no UCC financing 
statements of record naming Antinori as debtor.  Trust Company Bank is not a 
creditor of Antinori.  The machinery and equipment included in such assets 
are in all material respects in good condition and repair, normal wear and 
tear excepted, and all leases of real or personal property to which Antinori 
is a party are fully effective and afford Antinori peaceful and undisturbed 
possession of the subject matter of the lease.  To its knowledge, Antinori is 
not in violation of any material zoning, building, safety or environmental 
ordinance, regulation or requirement or other law or regulation applicable to 
the operation of owned or leased properties, and Antinori has not received 
any notice of such violation with which it has not complied or had waived.

                 2.10    ABSENCE OF CERTAIN CHANGES. Since the Balance Sheet 
Date, except as set forth in SCHEDULE 2.10, there has not been with respect 
to Antinori:

                         (a)    to the knowledge of Antinori, any change in 
the financial condition, properties, assets, liabilities business, results of 
operations or prospects of Antinori, which change by itself or in conjunction 
with all other such changes, whether or not arising in the ordinary course of 
business, has had or can reasonably be expected to have a material adverse 
effect on Antinori;

                         (b)    to the knowledge of Antinori, any contingent 
liability incurred by Antinori as guarantor or surety with respect to the 
obligations of others;

obligation or liability incurred by Antinori other than in the ordinary 
course of business;

                         (e)    any purchase or sale or other disposition, or 
any agreement or other arrangement for the purchase, sale or other 
disposition, of any of the properties or assets of Antinori other than in the 
ordinary course of business or in nonmaterial amounts;

                         (f)    to the knowledge of Antinori, any damage, 
destruction or loss, whether or not covered by insurance, materially and

          6.     CLOSING MATTERS

                 6.1     THE CLOSING.  Subject to termination of this Agreement
as provided in Section 9, the closing of the transactions provided for herein

Professional Corporation), 2200 Ross Avenue, Suite 2200, Dallas, Texas 75201 at
9:00 a.m., Dallas, Texas time on or before January 31, 1997, or, if all
conditions to Closing have not been satisfied or waived by such date, such other
place, time and date as Antinori and Carreker may mutually select (the "CLOSING
DATE").  Prior to or concurrently with the Closing, the Plan of Merger and such
officers' certificates or other documents as may be required to effectuate the
Merger will be filed in the offices of the Georgia Secretary of State and the
Texas Secretary of State.  Accordingly, the Merger will become effective at the
Effective Time.

                 6.2     EXCHANGE OF CERTIFICATES.

                         6.2.1     As of the Effective Time, all shares of
Antinori Common Stock that are outstanding immediately prior thereto will, by
virtue of the Merger and without further action, cease to exist, and all such
shares will be converted into the right to receive from Carreker the number of
shares of Carreker Class A Common Stock determined as set forth in Section 1.1,
subject to Sections 1.2 and 1.3, as identified on EXHIBIT 1.1.1.

                         6.2.2     At and after the Effective Time, each
certificate representing outstanding shares of Antinori Common Stock will
represent the number of shares of Carreker Class A Common Stock into which such
shares of Antinori Common Stock have been converted, and such shares of Carreker
Class A Common Stock will be deemed registered in the name of the holder of such
certificate.  As soon as practicable after the Effective Time, the holder of
shares of Antinori Common Stock will surrender (a) the certificates of such
shares (the "ANTINORI CERTIFICATES") to Carreker for cancellation or (b) an
affidavit of lost (or non-issued) certificate and agreement to indemnify in form
satisfactory to Carreker (an "AFFIDAVIT").  Promptly following the Effective
Time and receipt of the Antinori Certificates and of any Affidavits, Carreker
will issue to such surrendering holder certificate(s) for the number of shares
of Carreker Class A Common Stock to which such holder is entitled pursuant to
Section 1.1, subject to Section 1.2, less the shares of Carreker Class A Common
Stock deposited into escrow pursuant to Section 1.3, and Carreker will
distribute any cash payable under Section 1.2.

                         6.2.3     All shares of Carreker Class A Common Stock
(and, if applicable, cash in lieu of fractional shares) delivered upon the
surrender of Antinori Certificates in accordance with the terms hereof will be
delivered to the registered holder or placed in escrow with Escrow Agent, as
applicable.  After the Effective Time, there will be no further registration of
transfers of the shares of Antinori Common Stock on the stock transfer books of
Antinori.  If, after the Effective Time, Antinori Certificates are presented for
transfer or for any other 


AGREEMENT AND PLAN OF MERGER - Page 34

<PAGE>

reason, there will be canceled and exchanged and certificates therefor will 
be delivered or placed in escrow as provided in this Section 6.2.

                         6.2.4     Until Antinori Certificates representing
Antinori Common Stock outstanding prior to the Merger are surrendered pursuant
to Section 6.2.2 above, such certificates will be deemed, for all purposes, to
evidence ownership of (a) the number of shares of Carreker Class A Common Stock
into which the shares of Antinori Common Stock will have been converted, subject
to the obligation to place a portion thereof in escrow as required hereby, and
(b) if applicable, cash in lieu of fractional shares.

Antinori receives notice of any audit or examination by any taxing authority 
of any tax return for Antinori for any period prior to, or prior to and

Antinori, individually, of such notice and Ronald R. Antinori at his own 
expense may, if Antinori (rather than Ronald R. Antinori) defends such audit 
or examination, participate in such audit or examination and shall be kept 
apprised by Carreker of the progress of such audit or examination.  Carreker 
agrees that it will not agree to, and that it will not permit Antinori to

          11.    MISCELLANEOUS

                 11.1    GOVERNING LAW; DISPUTE RESOLUTION.  The laws of the 
State of Texas (without regard to its choice of law principles that might 
apply the law of another jurisdiction) will govern the validity of this 
Agreement, the construction of its terms, and the interpretation and 
enforcement of the rights and duties of the parties.  Any dispute hereunder 
("DISPUTE") shall be settled by arbitration in Dallas, Texas and, except as 
herein specifically stated, in accordance with the commercial arbitration 
rules of the American Arbitration Association ("AAA RULES") then in effect.  
However, in all events, these arbitration provisions shall govern over any 
conflicting rules that may now or hereafter be contained in the AAA Rules.  
Any judgment upon the award rendered by the arbitrator may be entered in any 
court having jurisdiction over the subject matter thereof.  The arbitrator 
shall have the authority to grant any equitable and legal remedies that would 
be available in any judicial proceeding instituted to resolve a Dispute.

                         11.1.1    COMPENSATION OF ARBITRATOR.  Any such 
arbitration will be conducted before a single arbitrator who will be 
compensated for his or her services at a rate to be determined by the parties 
or by the American Arbitration Association, but based upon a reasonable 
hourly or daily consulting rate for the arbitrator if the parties are not 
able to agree upon his or her rate of compensation.

                         11.1.2    SELECTION OF ARBITRATOR.  The American 
Arbitration Association will have the authority to select an arbitrator from 
a list of arbitrators who are lawyers familiar with Texas contract law and 
experienced in mergers and acquisitions; provided, however, that such lawyers 
cannot work for a firm then performing services for either party, that each 
party will have the opportunity to make such reasonable objection to any of 
the arbitrators listed as such party may wish and that the American 
Arbitration Association will select the arbitrator from the list of 
arbitrators as to whom neither party makes any such objection.  If the 
foregoing procedure is not followed, each party will choose one person from 
the list of arbitrators provided by the American Arbitration Association 
(provided that such person does not have a conflict of interest), and the two 
persons so selected will select from the list provided by the American 
Arbitration Association the person who will act as the arbitrator.

                         11.1.3    PAYMENT OF COSTS.  Carreker and Antinori 
will each pay 50% of the initial compensation to be paid to the arbitrator in 
any such arbitration and 50% of the costs of transcripts and other normal and 
regular expenses of the arbitration proceedings; provided, 

AGREEMENT AND PLAN OF MERGER - Page 40
<PAGE>

however, that the prevailing party in any arbitration will be entitled to an 
award of attorneys' fees and costs, and all costs of arbitration, including 
those provided for above, will be paid by the non-prevailing party, and the 
arbitrator will be authorized to make such determinations.

                         11.1.4    BURDEN OF PROOF.  For any Dispute 
submitted to arbitration, the burden of proof will be as it would be if the 
claim were litigated in a Texas judicial proceeding.

                         11.1.5    AWARD.  Upon the conclusion of any 
arbitration proceedings hereunder, the arbitrator will render findings of 
fact and conclusions of law and a written opinion setting forth the basis and 
reasons for any decision reached and will deliver such documents to each 
party to this Agreement along with a signed copy of the award.

                         11.1.6    TERMS OF ARBITRATION.  The arbitrator 
chosen in accordance with these provisions will not have the power to alter, 
amend or otherwise affect the terms of these arbitration provisions or the 
provisions of this Agreement.

                         11.1.7    EXCLUSIVE REMEDY.  Except as specifically 
otherwise provided in this Agreement, arbitration will be the sole and 
exclusive remedy of the parties for any Dispute arising out of this Agreement.

                 11.2    ASSIGNMENT; BINDING UPON SUCCESSORS AND ASSIGNS. 
Neither party may assign any of its rights or obligations hereunder without 
the prior written consent of the other party.  This Agreement will be binding 
upon and inure to the benefit of the parties and their respective successors 
and permitted assigns.

                 11.3    SEVERABILITY.  If any provision of this Agreement, 
or the application thereof, is for any reason held to any extent to be 
invalid or unenforceable, then the remainder of this Agreement and 
application of such provision to other persons or circumstances will be 
interpreted so as reasonably to effect the intent of the parties.  The 
parties further agree to replace such unenforceable provision of this 
Agreement with a valid and enforceable provisions that will achieve, to the 
extent possible, the economic, business and other purposes of the invalid or 
unenforceable provisions.

                 11.4    COUNTERPARTS.  This Agreement may be executed in

                 11.5    OTHER REMEDIES.  Except as otherwise provided 
herein, any and all remedies herein expressly conferred upon a party will be

or in a particular instance and either retroactively or prospectively), only 
by a writing signed by the party to be bound thereby. The waiver by a party 
of any breach hereof or default in the performance hereof will not be deemed 
to constitute a waiver of any other default of any succeeding breach or 
default.  This Agreement may be amended by the parties at any time.

                 11.7    NO WAIVER.  The failure of any party to enforce any 
of the provisions hereof will not be construed to be a waiver of the right of 
such party thereafter to enforce such provisions.  The waiver by any party of 
the right to enforce any of the provisions hereof on any occasion will not be 
construed to be a waiver of the right of such party to enforce such 
provisions on any other occasion.

expenses and fees of its own accountants, attorneys, investment bankers and

incurred by Antinori in excess of the applicable amount set forth for above 
are paid by the Antinori Shareholders on or before the Closing (and if such

such payment and, if not so reimbursed, Antinori will be entitled to treat 
the amount of payment as Carreker Damages recoverable under Section 10.2

                                    PLAN OF MERGER
                                          OF
                                   CAG NEWCO, INC.
                                    WITH AND INTO 
                               ANTINORI SOFTWARE, INC.


     This Plan of Merger (this "PLAN") is entered into as of January 29, 1997
among The Carreker Group, Inc., a Texas corporation ("CARREKER"), CAG Newco,
Inc., a Texas corporation and a wholly-owned subsidiary of Carreker ("NEWCO"),
and Antinori Software, Inc., a Georgia corporation ("ANTINORI").


















                                  Page 1

     1.    EFFECTIVE TIME OF MERGER.  Pursuant to the Texas Business
Corporation Act and the Georgia Business Corporation Code, Newco will be merged
with and into Antinori (the "MERGER") and Antinori will be the surviving
corporation of the Merger.  The Merger will be effective (the "EFFECTIVE TIME")
at 11:59 p.m., Dallas, Texas time, January 31, 1997, the date on which a copy of
this Plan is filed with the Secretary of State of Texas and the Secretary of
State of Georgia.

     2.    CONVERSION OF SECURITIES.

           (a)   CONVERSION OF SHARES.  At the Effective Time, each share of
Antinori Common Stock, $.01 par value ("ANTINORI COMMON STOCK"), issued and
outstanding immediately prior to the Effective Time, will, by virtue of the
Merger, be converted into 0.50946871 fully paid and nonassessable shares of
Carreker Class A Voting Common Stock, no par value ("CARREKER COMMON STOCK"). 
No fractional shares of Carreker Common Stock will be issued in connection with
the Merger, but in lieu thereof, Carreker will pay an amount of cash equal to
$23.83 multiplied by the fraction of a share of Carreker Common Stock to which
such holder would otherwise be entitled.  No Carreker Common Stock will be
issued or paid in exchange for any shares of Antinori Common Stock held by
Antinori as treasury stock. 

           (b)   ESCROW SHARES.  At the closing of the Merger, Carreker will
deduct from the shares of Carreker Common Stock to be delivered to former
holders of Antinori Common Stock (the "SHAREHOLDERS") a number of shares
equaling approximately (and less than) 5% of the shares of Carreker Common Stock
to be delivered to the Shareholders in the Merger pursuant to that certain
Escrow Agreement (the "ESCROW AGREEMENT"), dated of even date herewith among the
Shareholders, Carreker and U.S. Trust Company of Texas, N.A., as escrow agent
(the "ESCROW AGENT"), and will deliver such shares on behalf of the Shareholders
to the Escrow Agent, to be held in escrow pursuant to the Escrow Agreement to
secure the indemnification obligation of the Shareholders under the Agreement
(as hereinafter defined).

           (c)   NO CHANGE TO OUTSTANDING CARREKER STOCK.  Each share of
Carreker Common Stock outstanding immediately prior to the Effective Time will
continue to be an identical outstanding share of Carreker Common Stock following
the Merger.

           (d)   NEWCO COMMON STOCK.  At the Effective Time, each share of
Newco Common Stock that is issued and outstanding immediately prior to the
Effective Time shall be converted into one share of Antinori Common Stock.

           (e)   ANTINORI COMMON STOCK.  At the Effective Time, 


                                  Page 2

<PAGE>

Carreker shall own all of the issued and outstanding shares of Antinori 
Common Stock and Antinori shall become a wholly-owned subsidiary of Carreker.

     3.    DIRECTORS AND OFFICERS.  The directors and officers of Carreker and
Antinori after the Effective Time shall be the persons set forth in ANNEX 1
hereto.  Such directors and officers will hold their positions as directors and
officers until the election and qualifications of their respective successors or
until their tenure is otherwise terminated in accordance with the bylaws of
Carreker or Antinori respectively.

     4.    AGREEMENT.  Antinori, Newco and Carreker are also parties to that
certain Agreement and Plan of Merger dated as of January 29, 1997 (the
"AGREEMENT").  The Agreement and this Plan are intended to be construed together
in order to effectuate their purposes.

     5.    FURTHER ASSURANCES.  After the Effective Time, Carreker and any of
its officers and directors may execute and deliver such deeds, assignments and
assurances and do all other things necessary or desirable to carry out the
purposes of this Plan, in the name of Antinori, Newco or otherwise.

     6.    ARTICLES OF INCORPORATION; BYLAWS.  The articles of incorporation
and bylaws of Antinori will not be amended by virtue of the Merger.

     7.    TERMINATION.  This Plan may be terminated and the proposed Merger
abandoned at any time prior to the Effective Time, whether before or after
approval of this  Plan or by the mutual consent of the Boards of Directors of
Carreker and Antinori.

     8.    ASSIGNMENT.  None of the parties may assign any of its rights or
obligations hereunder without the prior written consent of the other parties. 
This Plan will be binding upon and inure to the benefit of the parties and their
respective successors and permitted assigns.

     9.    GOVERNING LAW.  The laws of the State of Texas (without regard to
its choice of law principles that might apply the law of another jurisdiction)
will govern the validity of this Plan, the construction of its terms and the
interpretation and enforcement of the rights and duties of the parties.

     10.   COUNTERPARTS.  This Plan may be executed in counterparts, each of
which will be an original as regards any party whose signature appears thereon
and all of which together will constitute one and the same instrument.  This
Plan will become binding when one or more counterparts hereof, individually 


                                  Page 3

<PAGE>

or taken together, bear the signatures of both parties reflected hereon as 
signatories.

     IN WITNESS WHEREOF, the parties have executed this Plan as of the date
first above written.

                              EMPLOYMENT AGREEMENT

     This EMPLOYMENT AGREEMENT (this "AGREEMENT") shall become effective as 
of the Effective Date indicated below between The Carreker Group, Inc., a 
Texas corporation ("CARREKER"), and Lawrence D. Duckworth ("MR. DUCKWORTH").

                                    RECITALS

     A.  This Agreement is entered into connection with and is ancillary to 
an Agreement and Plan of Merger (the "AGREEMENT") dated as of January 29, 
1997 between Carreker and Antinori Software Inc., a Georgia corporation, 
pursuant to which a wholly-owned subsidiary of Carreker is to merge with and 
into Antinori Software, Inc. (the "MERGER"), such that Antinori Software, 
Inc. will become a wholly-owned subsidiary of Carreker.  The date on which 
the Merger becomes effective will be the effective date of this Agreement 
(the "EFFECTIVE DATE"). As provided in Section 9(h) below, this Agreement 
will be void and have no effect if the Merger does not become effective, 
i.e., the Effective Date does not occur, by February 1, 1997.

     B.  Mr. Duckworth is the President, Chief Executive Officer and a 
director of Antinori Software, Inc., reporting to the Chairman of its board 
of directors, and has been and remains actively involved in the development 
and marketing of Antinori Software, Inc.'s products.  Carreker intends to 
continue the business of Antinori Software, Inc. after the Merger and 
integrate such business into Carreker's ongoing business.  To preserve and 
protect the assets of Antinori Software, Inc., including Antinori Software, 
Inc.'s goodwill, customers and trade secrets of which Mr. Duckworth has and 
will have knowledge and to preserve and protect Carreker's goodwill and 
business interests going forward, and in consideration for Carreker's 
entering into and performing under the Agreement, Mr. Duckworth has agreed to 
enter into this Agreement.

     C.  In addition, as contemplated by Section 7 below, Mr. Duckworth is 
concurrently herewith entering into an Intellectual Property Rights Agreement 
and a Confidentiality Agreement in favor of Carreker for the purpose of 
protecting Carreker's proprietary rights.

     NOW, THEREFORE, in consideration of the foregoing and the mutual 
agreements of the parties contained herein, Carreker and Mr. Duckworth hereby 
agree as follows:
                                       
                                     Page 1
<PAGE>

     1.    EMPLOYMENT.   Carreker will employ Mr. Duckworth and Mr. Duckworth 
accepts employment with Carreker for a period of two years from the Effective 
Date (the "INITIAL PERIOD"), unless Mr. Duckworth's employment is sooner 
terminated in accordance with this Agreement.  Mr. Duckworth's employment may 
continue after the Initial Period but will then be terminable by either party 
at will, with or without cause, which determination may be made in its sole 
discretion.  The obligations of Carreker and Mr. Duckworth set forth in the 
"Intellectual Property Rights Agreement" and the "Confidentiality Agreement" 
(each as defined in Section 7) (referring to intellectual property and 
confidentiality, respectively) and in Section 8 (referring to termination) 
will survive termination of Mr. Duckworth's employment, regardless of cause.

           Mr. Duckworth's primary location of employment shall be in 
Atlanta, Georgia or its environs, and he shall undertake such business travel 
as is reasonably required in the discharge of his duties set forth below.

     2.    DUTIES.  Mr. Duckworth will be employed as a full-time employee of 
Carreker and initially will serve as the President of its Software Group and 
as a director.  Unless and until the board of directors of Carreker changes 
reporting responsibilities, which change the board may make in its sole 
discretion, Mr. Duckworth shall report to the Chairman and Chief Executive 
Officer of Carreker.  Mr. Duckworth agrees that, to the best of his ability 
and experience, he will at all times conscientiously perform all of the 
duties and obligations assigned to him under this Agreement.

     3.    FULL-TIME EMPLOYMENT.  Mr. Duckworth's employment will be on a 
full-time basis, in accordance with standard employee policies for Carreker.  
Mr. Duckworth will not engage in any other business or render any commercial 
or professional services, directly or indirectly, to any other person or 
organization, whether for compensation or otherwise, provided that Mr. 
Duckworth may (i) provide incidental assistance to family members on matters 
of family business; and (ii) sit on the board of directors of corporations 
and other organizations (including, without limitation, charitable and other 
nonprofit organizations) that do not compete with Carreker; provided in each 
case that such activities do not conflict with or interfere with Mr. 
Duckworth's normal full-time and first priority obligations to Carreker.  Mr. 
Duckworth may make personal investments in nonpublicly traded corporations, 
partnerships or other entities that, to the knowledge of Carreker, are not at 
the time of such investment engaged in any business activities competitive 
with Carreker. Notwithstanding anything to the contrary contained in this 
Agreement, Mr. Duckworth may make personal investments in publicly traded 
corporations regardless of the business they are engaged in, provided that 
Mr. Duckworth does not at any time own in excess 

                                     Page 2
<PAGE>

of 1% of the issued and outstanding stock of any such corporation.

     4.    SALARY; POTENTIAL BONUS; OPTIONS.  Mr. Duckworth's salary for the 
term of the Initial Period will be not less than $250,000 per year, payable 
on Carreker's regular payroll dates, less required withholdings.  Carreker 
agrees to review Mr. Duckworth's salary on or about six months after the 
Effective Date; PROVIDED, HOWEVER, that such review shall not result in a 
salary reduction, and a salary increase, if any, shall be totally within 
Carreker's discretion.

     The board of directors of Carreker has the sole discretion whether or 
not to establish a bonus pool.  If and to the extent the board of directors 
of Carreker establishes a bonus pool for 1997 or any subsequent year, then 
Mr. Duckworth will be entitled to participate in the same at a percentage 
level reasonably consistent with the participation of other high level 
executive officers (e.g., the chief executive officer and chief financial 
officer, etc.) of Carreker.

     On the Effective Date, Carreker shall grant to Mr. Duckworth options to 
purchase up to 33,300 shares of Carreker's Class B Common Stock at an 
exercise price of $19.07 per share.  One such option shall be an incentive 
stock option to the extent allowable by law and shall vest one-third on the 
Effective Date, one-third on the first anniversary thereof and one-third on 
the second anniversary thereof.  The other such option shall be a 
non-qualified option with identical vesting terms.  Such options shall be 
issued under and pursuant to Carreker's existing long term incentive plan, 
with terms and conditions as provided therein except as expressly provided 
above.

     5.    BENEFITS.  Mr. Duckworth will also be entitled to insurance, 
vacation and other benefits commensurate with his position in accordance with 
Carreker's standard employee policies in effect from time to time.  Mr. 
Duckworth acknowledges receipt of a summary of Carreker's standard employee 
benefits policies in effect as of the date hereof.

     6.    REIMBURSEMENT OF BUSINESS EXPENSES.  Carreker will, in accordance 
with Carreker's policies in effect from time to time, reimburse Mr. Duckworth 
for all out-of-pocket reasonable business expenses incurred by Mr. Duckworth 
in connection with the performance of his duties under this Agreement upon 
submission of the required documentation required pursuant to Carreker's 
standard policies and record-keeping procedures.

     7.    INTELLECTUAL PROPERTY.  Simultaneously with the execution of this 
Agreement, Mr. Duckworth is executing and delivering and hereby adopts and 
agrees to be bound by Carreker's Intellectual Property Rights Agreement, a 
copy of which is attached to this Agreement as ATTACHMENT A, and the 

                                     Page 3
<PAGE>

Confidentiality Agreement, a copy of which is attached to this Agreement as 
ATTACHMENT B.

     8.    TERMINATION.

           (a)   CARREKER.  Carreker may terminate Mr. Duckworth's employment 
at any time during the Initial Period with or without cause upon written 
notice to Mr. Duckworth.

           (b)   BY MR. DUCKWORTH.  During the Initial Period, Mr. Duckworth 
may terminate Mr. Duckworth's employment upon written notice to Carreker only 
if Carreker is in material breach of this Agreement, provided that such 
termination will become effective only upon the expiration of 30 days 
following such notice and then only if the breach remains uncured.  Such 
termination shall be deemed a termination by Carreker of Mr. Duckworth's 
employment under Section 8(a) for which Mr. Duckworth shall have the remedy 
set forth in Section 8(c).

           (c)   REMEDY.  Upon termination of Mr. Duckworth's employment 
pursuant to Section 8(a) without cause or Section 8(b) only (at which time he 
shall cease to be an employee of Carreker for all purposes, including for all 
benefit plan, insurance and other purposes), Carreker will pay to Mr. 
Duckworth, on Carreker's regular payroll dates and less required withholdings 
(if any), salary at the rate paid to Mr. Duckworth immediately prior to such 
termination, for the lesser of (i) the balance of the Initial Period or (ii) 
one year (the "TERMINATION PAYMENTS").  Carreker's obligation to make the 
Termination Payments pursuant to this Section 8(c) is in lieu of any damages 
or any other payment or benefits, including without limitation stock 
benefits, that Carreker might otherwise be obligated to pay Mr. Duckworth as 
a result of Mr. Duckworth's termination of employment; PROVIDED, HOWEVER, 
that if at any time Carreker terminates Mr. Duckworth's employment without 
cause under circumstances in which Mr. Duckworth is not entitled to 
Termination Payments, or is entitled to Termination Payments that in the 
aggregate are less than a lump-sum severance payment consistent with 
Carreker's standard severance payment policy, if any, as may be in effect at 
the time of termination, determined with applicable credit for Mr. 
Duckworth's time of service with Antinori Software, Inc., then Mr. Duckworth 
shall be entitled to such lump-sum severance payment.  (For purposes of 
reference and example only, Carreker's standard severance payment policy as 
of the date of this Agreement provides for the payment of one week's salary 
at the time of termination for each year of service as an employee.)  
Carreker and Mr. Duckworth agree that, in view of the nature of the issues 
likely to arise in the event of such a termination, it would be impracticable 
or extremely difficult to fix the actual damages resulting from such 
termination and proving actual damages, causation and foreseeability in the 
case of such termination would be costly, inconvenient and difficult.  In 
requiring Carreker to 

                                     Page 4
<PAGE>

make the Termination Payments as set forth herein, it is the intent of the 
parties to provide, as of the date of this Agreement, for a liquidated amount 
of damages to be paid by Carreker to Mr. Duckworth.  Such liquidated amount 
shall be deemed full and adequate damages for such termination and is not 
intended by either party to be a penalty.

           (d)   UPON DEATH.  If Mr. Duckworth dies during the term of this 
Agreement, then Carreker will pay his estate an amount equal to all salary 
accrued, bonuses (if any) accrued and payable and benefits accrued as of the 
date of his death.

           (e)   SURVIVAL.  Mr. Duckworth's and Carreker's obligations under 
Sections 7, 8 and 9(i) of this Agreement will survive the termination of 
Carreker's employment of Mr. Duckworth.

           (f)   OPTIONS.  Termination of Mr. Duckworth's employment with 
Carreker shall not of itself make unexercisable any unexercised options to 
purchase stock of Carreker except and to the extent expressly provided for 
(or referenced) in the agreements evidencing such options.

           (g)   CAUSE.  As used in this Agreement the term "with cause" 
shall mean and be limited to:  (i) a material breach of this Agreement by Mr. 
Duckworth that is not corrected within thirty (30) days after written notice 
of same from the board of directors of Carreker to Mr. Duckworth; (ii) gross 
and willful neglect by Mr. Duckworth of his duties and responsibilities 
hereunder; (iii) fraud, criminal misconduct, breach of fiduciary duty, 
dishonesty, or gross and willful misconduct by Mr. Duckworth in connection 
with the performance of his duties and responsibilities hereunder; (iv) Mr. 
Duckworth being under the influence of alcohol or drugs during business 
hours, or being habitually drunk or addicted to drugs; (v) the commission by 
Mr. Duckworth of any crime of moral turpitude; (vi) material breach by Mr. 
Duckworth of his obligations under any assignment of copyright and other 
intellectual property rights, noncompetition agreement, trade secret 
agreement or confidentiality agreement, which breach is not cured within 
thirty (30) days after written notice of same from the board of directors of 
Carreker to Mr. Duckworth; or (vii) habitual breach by Mr. Duckworth of any 
of the material provisions of this Agreement or such other assignment or 
agreements (regardless of any prior cure thereof).

     9.    MISCELLANEOUS.

           (a)   NOTICES.  Any and all notice permitted or required to be

HOWEVER, that this sentence does not supersede and is without prejudice to 
Mr. Duckworth's vested option to purchase shares of Carreker from Ronald R. 
Antinori 

                                     Page 6
<PAGE>

(individually) as set forth in paragraph 3 of such Letter of Agreement (and 
the vesting and acceleration provisions of paragraph 4 of such Letter of 
Agreement, to the extent they relate to such paragraph 3).  This Agreement 
may not be changed or modified in whole or in part except by a writing signed 
by the party against whom enforcement of the change or modifications is 
sought.

          (c)    SUCCESSORS AND ASSIGNS.  This Agreement will not be 
assignable by either Mr. Duckworth or Carreker, except that the rights and 
obligations of Carreker under this Agreement may be assigned to a corporation 
which succeeds Carreker as the result of a merger or other corporate 
reorganization and which continues the business of Carreker, or subsidiary of 
Carreker, provided that Carreker guarantees the performance by such assignee 
of Carreker's obligations hereunder.

          (d)    GOVERNING LAW.  The laws of the State of Texas (without 
regard to its choice of law principles that might apply the law of another 
jurisdiction) will govern the validity of this Agreement, the construction of 
its terms, and the interpretation and enforcement of the rights and duties of 
the parties.

          (e)    NO WAIVER.  The failure of any party to enforce any of the 
provisions hereof will not be construed to be a waiver of the right of such 
party thereafter to enforce such provisions.  The waiver by any party of the 
right to enforce any of the provisions hereof on any occasion will not be 
construed to be a waiver of the right of such party to enforce such 
provisions on any other occasion.

          (f)    SEVERABILITY.  Mr. Duckworth and Carreker recognize that the 
limitations contained in this Agreement are reasonably and properly required 
for the adequate protection of the interests of Carreker.  If for any reason 
a court of competent jurisdiction or an arbitrator in a binding arbitration 
proceeding finds any provision of this Agreement, or the application thereof, 
to be unenforceable, then the remaining provisions of this Agreement will be 
interpreted so as best to reasonably effect the intent of the parties.  The 
parties further agree that the court or arbitrator shall replace any such 
invalid or unenforceable provisions with valid and enforceable provisions 
designed to achieve, to the extent possible, the business purposes and intent 
of such unenforceable provisions.

          (g)    COUNTERPARTS.  This Agreement may be executed in 
counterparts, each of which will be an original as regards any party whose 
signature appears thereon and all of which together will constitute one and 
the same instrument. This Agreement will become binding when one or more 
counterparts hereof, individually or taken together, bear the signatures of 
both parties reflected hereon as signatories.

          (h)    EFFECT OF AGREEMENT.  This Agreement will be void and have 
no effect if the Effective Date does not occur on or before February 1, 1997.

          (i)    DISPUTE RESOLUTION.

                 (i)     ARBITRATION OF DISPUTES.  Any dispute under this 
Agreement shall be resolved by arbitration in Dallas, Texas and, except as 
herein specifically stated, in accordance with the commercial arbitration 
rules of the American Arbitration Association ("AAA RULES") then in effect.  
However, in all events, these arbitration provisions shall govern over any 
conflicting rules that may now or hereafter be contained in the AAA Rules.  
Any judgment upon the award rendered by the arbitrator may be entered in any 
court having jurisdiction over the subject matter thereof.  The arbitrator 
shall have the authority to grant any equitable and legal remedies that would 
be available in any judicial proceeding instituted to resolve such dispute.

                 (ii)    COMPENSATION OF ARBITRATOR.  Any such arbitration 
will be conducted before a single arbitrator who will be compensated for his 
or her services at a rate to be determined by the parties or by the American 
Arbitration Association, but based upon reasonable hourly or daily consulting 
rates for the arbitrator if the parties are not able to agree upon his or her 
rate of compensation.

                 (iii)   SELECTION OF ARBITRATOR.  The American Arbitration 
Association will have the authority to select an arbitrator from a list of 
arbitrators who are lawyers familiar with Texas contract law; PROVIDED, 
HOWEVER, that such lawyers cannot work for a firm then performing services 
for either party, that each party will have the opportunity to make such 
reasonable objection to any of the arbitrators listed as such party may wish 
and that the American Arbitration Association will select the arbitrator from 
the list of arbitrators as to whom neither party makes any such objection.  
If the foregoing procedure is not followed, then each party will choose one 
person from the list of arbitrators provided by the American Arbitration 
Association (provided that such person does not have a conflict of interest), 
and the two persons so selected will select from the list provided by the 
American Arbitration Association the person who will act as the arbitrator.

                 (iv)    PAYMENT OF COSTS.  Carreker and Mr. Duckworth will 
each pay 50% of the initial compensation to be paid to the arbitrator in any 
such arbitration and 50% of the costs of transcripts and other normal and 
regular expenses of the arbitration proceedings; PROVIDED, HOWEVER, that the 
prevailing party in any arbitration will be entitled to an award of 
attorneys' fees and costs, and all costs of arbitration, including 

                                     Page 8
<PAGE>

those provided for above, will be paid by the non-prevailing party, and the 
arbitrator will be authorized to make such determinations.

                 (v)     BURDEN OF PROOF.  For any dispute submitted to 
arbitration, the burden of proof will be as it would be if the claim were 
litigated in a Texas judicial proceeding.

                 (vi)    AWARD.  Upon the conclusion of any arbitration 
proceedings hereunder, the arbitrator will render findings of fact and 
conclusions of law and a written opinion setting forth the basis and reasons 
for any decision reached and will deliver such documents to each party to 
this Agreement along with a signed copy of the award.

                 (vii)   TERMS OF ARBITRATION.  The arbitrator chosen in 
accordance with these provisions will not have the power to alter, amend or 
otherwise affect the terms of these arbitration provisions or the provisions 
of this Agreement.

                 (viii)  EXCLUSIVE REMEDY.  Except as specifically otherwise 
provided in this Agreement, arbitration will be the sole and exclusive remedy 
of the parties for any dispute arising out of this Agreement.

                 (ix)    EQUITABLE REMEDY.  Notwithstanding the provisions of 
this Section 9(i) and the arbitration provided for herein, actions initiated 
or maintained by the parties for injunctive or similar equitable relief may 
not be subject to arbitration and may be brought by the parties in any court 
that has jurisdiction, and should the party bringing any such action prevail, 
all costs and expenses (including legal fees) shall be borne by the party 
against whom such action was brought.

                              EMPLOYMENT AGREEMENT

      This EMPLOYMENT AGREEMENT (this "AGREEMENT") shall become effective as 
of the Effective Date indicated below between The Carreker Group, Inc., a 
Texas corporation ("CARREKER"), and Mr. Michael Israel ("MR. ISRAEL").

                                    RECITALS

      A.  This Agreement is entered into connection with and is ancillary to 
an Agreement and Plan of Merger (the "AGREEMENT") dated as of January 29, 
1997 between Carreker and Antinori Software Inc., a Georgia corporation, 
pursuant to which a wholly-owned subsidiary of Carreker is to merge with and 
into Antinori Software, Inc. (the "MERGER"), such that Antinori Software, 
Inc. will become a wholly-owned subsidiary of Carreker.  The date on which 
the Merger becomes effective will be the effective date of this Agreement 
(the "EFFECTIVE DATE"). As provided in Section 9(h) below, this Agreement 
will be void and have no effect if the Merger does not become effective, 
i.e., the Effective Date does not occur, by February 1, 1997.

      B.  Mr. Israel is a Vice President and a shareholder of Antinori 
Software, Inc. and has been and remains actively involved in the development 
and marketing of Antinori Software, Inc.'s products.  Carreker intends to 
continue the business of Antinori Software, Inc. after the Merger and 
integrate such business into Carreker's ongoing business.  To preserve and 
protect the assets of Antinori Software, Inc., including Antinori Software, 
Inc.'s goodwill, customers and trade secrets of which Mr. Israel has and will 
have knowledge and to preserve and protect Carreker's goodwill and business 
interests going forward, and in consideration for Carreker's entering into 
and performing under the Agreement, Mr. Israel has agreed to enter into this 
Agreement.

      C.  In addition, as contemplated by Section 7 below, Mr. Israel is 
concurrently herewith entering into an Intellectual Property Rights Agreement 
and a Confidentiality Agreement in favor of Carreker for the purpose of 
protecting Carreker's proprietary rights.

      NOW, THEREFORE, in consideration of the foregoing and the mutual 
agreements of the parties contained herein, Carreker and Mr. Israel hereby 
agree as follows:

                                     Page 1
<PAGE>

      1.   EMPLOYMENT.   Carreker will employ Mr. Israel and Mr. Israel 
accepts employment with Carreker.  Mr. Israel's employment is terminable by 
either party at will, with or without cause, at any time.  The obligations of 
Carreker and Mr. Israel set forth in the "Intellectual Property Rights 
Agreement" and the "Confidentiality Agreement") (each as defined in Section 
7) (referring to intellectual property and confidentiality, respectively) and 
in Section 8 (referring to termination) will survive termination of Mr. 
Israel's employment, regardless of cause.

           Mr. Israel's primary location of employment shall be in Atlanta, 
Georgia or its environs, and he shall undertake such business travel as is 
reasonably required in the discharge of his duties set forth below.

      2.   DUTIES.  Mr. Israel will be employed as a full-time employee of 
Carreker.  Mr. Israel agrees that, to the best of his ability and experience, 
he will at all times conscientiously perform all of the duties and 
obligations assigned to him under this Agreement, which shall be reasonably 
comparable to his duties and obligations at Antinori Software, Inc.

      3.   FULL-TIME EMPLOYMENT.  Mr. Israel's employment will be on a 
full-time basis, in accordance with standard employee policies for Carreker.  
Mr. Israel will not engage in any other business or render any commercial or 
professional services, directly or indirectly, to any other person or 
organization, whether for compensation or otherwise, provided that Mr. Israel 
may (i) provide incidental assistance to family members on matters of family 
business; and (ii) sit on the board of directors of corporations and other 
organizations (including, without limitation, charitable and other nonprofit 
organizations) that do not compete with Carreker; provided in each case that 
such activities do not conflict with or interfere with Mr. Israel's normal 
full-time and first priority obligations to Carreker.  Mr. Israel may make 
personal investments in nonpublicly traded corporations, partnerships or 
other entities that, to the knowledge of Carreker, are not at the time of 
such investment engaged in any business activities competitive with Carreker. 
Notwithstanding anything to the contrary contained in this Agreement, Mr. 
Israel may make personal investments in publicly traded corporations 
regardless of the business they are engaged in, provided that Mr. Israel does 
not at any time own in excess of 1% of the issued and outstanding stock of 
any such corporation.

      4.   SALARY; OPTIONS.  Mr. Israel's initial salary will be not less 
than the rate of $130,000 per year, payable on Carreker's regular payroll 
dates, less required withholdings.  Changes in Mr. Israel's salary shall 
occur only by mutual agreement.

      On the Effective Date, Carreker shall grant to Mr. Israel 

                                     Page 2
<PAGE>

options to purchase up to 23,100 shares of Carreker's Class B Common Stock at 
an exercise price of $19.07 per share.  One such option shall be an incentive 
stock option to the extent allowable by law and shall vest one-third on the 
Effective Date, one-third on the first anniversary thereof and one-third on 
the second anniversary thereof.  The other such option shall be a 
non-qualified option with identical vesting terms.  Such options shall be 
issued under and pursuant to Carreker's existing long term incentive plan, 
with terms and conditions as provided therein except as expressly provided 
above.

      5.   BENEFITS.  Mr. Israel will be entitled to insurance, vacation and 
other benefits commensurate with his position in accordance with Carreker's 
standard employee policies in effect from time to time.  Mr. Israel 
acknowledges receipt of a summary of Carreker's standard employee benefits 
policies in effect as of the date hereof.

      6.   REIMBURSEMENT OF BUSINESS EXPENSES.  Carreker will, in accordance 
with Carreker's policies in effect from time to time, reimburse Mr. Israel 
for all out-of-pocket reasonable business expenses incurred by Mr. Israel in 
connection with the performance of his duties under this Agreement upon 
submission of the required documentation required pursuant to Carreker's 
standard policies and record-keeping procedures.

      7.   INTELLECTUAL PROPERTY.  Simultaneously with the execution of this 
Agreement, Mr. Israel is executing and delivering and hereby adopts and 
agrees to be bound by Carreker's Intellectual Property Agreement, a copy of 
which is attached to this Agreement as ATTACHMENT A, and the Confidentiality 
Agreement, a copy of which is attached to this Agreement as ATTACHMENT B.

      8.   SURVIVAL.  Mr. Israel's and Carreker's obligations under Sections 
7, 8 and 9(i) of this Agreement will survive the termination of Carreker's 
employment of Mr. Israel.

      9.   MISCELLANEOUS.

           (a)   NOTICES.  Any and all notice permitted or required to be 
given under this Agreement must be in writing.  Notices will be deemed given

           (b)   AMENDMENTS.  This Agreement, including the Attachments 
hereto, contains the entire agreement and supersedes and replaces all prior 
agreements between Carreker and Mr. Israel, or between Antinori Software, 
Inc. and Mr. Israel, concerning Mr. Israel's employment and employment 
benefits (including, without limitation, those certain Letters of Agreement 
dated December 20, 1994 and September 13, 1996, each between Mr. Israel and 
Antinori Software, Inc., but not his accrued rights to commissions as set 
forth in those agreements).  This Agreement may not be changed or modified in 
whole or in part except by a writing signed by the party against whom 
enforcement of the change or modifications is sought.

           (c)   SUCCESSORS AND ASSIGNS.  This Agreement will not be 
assignable by either Mr. Israel or Carreker, except that the rights and 
obligations of Carreker under this Agreement may be assigned to a corporation 
which succeeds Carreker as the result of a merger or other corporate 
reorganization and which continues the business of Carreker, or a subsidiary 
of Carreker, provided that 

                                     Page 4
<PAGE>

Carreker guarantees the performance by such assignee of Carreker's 
obligations hereunder.

           (d)   GOVERNING LAW.  The laws of the State of Texas (without 
regard to its choice of law principles that might apply the law of another 
jurisdiction) will govern the validity of this Agreement, the construction of 
its terms, and the interpretation and enforcement of the rights and duties of 
the parties.

           (e)   NO WAIVER.  The failure of any party to enforce any of the 
provisions hereof will not be construed to be a waiver of the right of such 
party thereafter to enforce such provisions.  The waiver by any party of the 
right to enforce any of the provisions hereof on any occasion will not be 
construed to be a waiver of the right of such party to enforce such 
provisions on any other occasion.

           (f)   SEVERABILITY.  Mr. Israel and Carreker recognize that the 
limitations contained in this Agreement are reasonably and properly required 
for the adequate protection of the interests of Carreker.  If for any reason 
a court of competent jurisdiction or an arbitrator in a binding arbitration 
proceeding finds any provision of this Agreement, or the application thereof, 
to be unenforceable, then the remaining provisions of this Agreement will be 
interpreted so as best to reasonably effect the intent of the parties.  The 
parties further agree that the court or arbitrator shall replace any such 
invalid or unenforceable provisions with valid and enforceable provisions 
designed to achieve, to the extent possible, the business purposes and intent 
of such unenforceable provisions.

           (g)   COUNTERPARTS.  This Agreement may be executed in 
counterparts, each of which will be an original as regards any party whose 
signature appears thereon and all of which together will constitute one and 
the same instrument. This Agreement will become binding when one or more 
counterparts hereof, individually or taken together, bear the signatures of 
both parties reflected hereon as signatories.

           (h)   EFFECT OF AGREEMENT.  This Agreement will be void and have 
no effect if the Effective Date does not occur on or before February 1, 1997.

           (i)   DISPUTE RESOLUTION.

                 (i)     ARBITRATION OF DISPUTES.  Any dispute under this 
Agreement shall be resolved by arbitration in Dallas, Texas and, except as 
herein specifically stated, in accordance with the commercial arbitration 
rules of the American Arbitration Association ("AAA RULES") then in effect.  
However, in all events, these arbitration provisions shall govern over any 
conflicting rules that may now or hereafter be contained in the AAA Rules.  

                                     Page 5
<PAGE>

Any judgment upon the award rendered by the arbitrator may be entered in any 
court having jurisdiction over the subject matter thereof.  The arbitrator 
shall have the authority to grant any equitable and legal remedies that would 
be available in any judicial proceeding instituted to resolve such dispute.

                 (ii)    COMPENSATION OF ARBITRATOR.  Any such arbitration 
will be conducted before a single arbitrator who will be compensated for his 
or her services at a rate to be determined by the parties or by the American 
Arbitration Association, but based upon reasonable hourly or daily consulting 
rates for the arbitrator if the parties are not able to agree upon his or her 
rate of compensation.

                 (iii)   SELECTION OF ARBITRATOR.  The American Arbitration 
Association will have the authority to select an arbitrator from a list of 
arbitrators who are lawyers familiar with Texas contract law; PROVIDED, 
HOWEVER, that such lawyers cannot work for a firm then performing services 
for either party, that each party will have the opportunity to make such 
reasonable objection to any of the arbitrators listed as such party may wish 
and that the American Arbitration Association will select the arbitrator from 
the list of arbitrators as to whom neither party makes any such objection.  
If the foregoing procedure is not followed, then each party will choose one 
person from the list of arbitrators provided by the American Arbitration 
Association (provided that such person does not have a conflict of interest), 
and the two persons so selected will select from the list provided by the 
American Arbitration Association the person who will act as the arbitrator.

                 (iv)    PAYMENT OF COSTS.  Carreker and Mr. Israel will each 
pay 50% of the initial compensation to be paid to the arbitrator in any such 
arbitration and 50% of the costs of transcripts and other normal and regular 
expenses of the arbitration proceedings; PROVIDED, HOWEVER, that the 
prevailing party in any arbitration will be entitled to an award of 
attorneys' fees and costs, and all costs of arbitration, including those 
provided for above, will be paid by the non-prevailing party, and the 
arbitrator will be authorized to make such determinations.

                 (v)     BURDEN OF PROOF.  For any dispute submitted to 
arbitration, the burden of proof will be as it would be if the claim were 
litigated in a Texas judicial proceeding.

                 (vi)    AWARD.  Upon the conclusion of any arbitration 
proceedings hereunder, the arbitrator will render findings of fact and 
conclusions of law and a written opinion setting forth the basis and reasons 
for any decision reached and will deliver such documents to each party to 
this Agreement along with a signed copy of the award.

                 (vii)   TERMS OF ARBITRATION.  The arbitrator chosen in 
accordance with these provisions will not have the power to alter, amend or 
otherwise affect the terms of these arbitration provisions or the provisions 
of this Agreement.

                 (viii)  EXCLUSIVE REMEDY.  Except as specifically otherwise 
provided in this Agreement, arbitration will be the sole and exclusive remedy 
of the parties for any dispute arising out of this Agreement. 

                 (ix)    EQUITABLE REMEDY.  Notwithstanding the provisions of 
this Section 9(i) and the arbitration provided for herein, actions initiated 
or maintained by the parties for injunctive or similar equitable relief may 
not be subject to arbitration and may be brought by the parties in any court 
that has jurisdiction, and should the party bringing any such action prevail, 
all costs and expenses (including legal fees) shall be borne by the party 
against whom such action was brought.

[Exhibit C includes a Noncompetition Agreement for each of Ronald R. Antinori,
Lawrence Duckwork, Michael Israel and Susan Antinori. A form of the 
Noncompetition Agreement is filed herewith.]


<PAGE>
                               NONCOMPETITION AGREEMENT

      This NONCOMPETITION AGREEMENT (this "AGREEMENT") is made as of the
Effective Date indicated below by and between The Carreker Group, Inc., a Texas
corporation ("CARREKER"), and __________________ ("SHAREHOLDER").

                                       RECITALS

      A.  This Agreement is entered into in connection with and is ancillary to
that certain Agreement and Plan of Merger (the "Plan") dated as of January 29,
1997 among Carreker, Antinori Software, Inc., a Georgia corporation
("ANTINORI"), and CAG Newco, Inc., a Texas corporation and a wholly-owned
subsidiary of Carreker, pursuant to which CAG Newco, Inc. will merge with and
into Antinori (the "MERGER").  The date on which the Merger becomes effective
will be the effective date of this Agreement (the "EFFECTIVE DATE").

      B.  Shareholder is a principal shareholder of Antinori and has been 
actively involved in the development and marketing of Antinori's products.  
Carreker intends to continue the business of Antinori after the Merger and 
integrate such business into Carreker's ongoing business. To preserve and 
protect the assets of Antinori, including Antinori's goodwill, customers and 
trade secrets of which Shareholder has and will have knowledge in his role as 
an employee of Carreker and to preserve and protect Carreker's goodwill and 
business interests going forward, and in consideration for Carreker's 
entering into and performing under the Plan, Shareholder has agreed to enter 
into this Agreement.

      C.  Shareholder and Carreker believe the limitation as to time,
geographical area and scope of activity contained in this Agreement are
reasonably necessary to, and no greater than that required to, protect the
goodwill and business interests of Carreker.

      NOW, THEREFORE, in consideration of the foregoing and the mutual
agreements of the parties contained herein, Carreker and Shareholder hereby
agree as follows:

      1.   TIME; SCOPE OF ACTIVITY.  For the later of three years following the
Effective Date and two years after the termination of Shareholder's employment
by Carreker, Shareholder will not (except to the extent permitted in Section 3
of Shareholder's Employment Agreement with Carreker dated the date of this
Agreement) individually or as an employee, partner, officer, director or
shareholder or in any other capacity whatsoever of or 


                               Page 1

Carreker, Antinori or other subsidiaries of Carreker:

           (a)   Own, manage, operate, sell, control or participate in the
ownership, management, operation, sales or control of any business engaged, in
the geographical area referred to in Section 2 below, in a business that is
substantially similar to or competitive with the development, marketing,
maintenance, administration, and consultation with respect to, computer software
for financial institutions or other computer software or other products created,
distributed or known by him to be under development by Carreker or any of its
subsidiaries prior to the termination of Shareholder's employment with Carreker;
or

           (b)   Directly or indirectly create, develop, sell, license or
otherwise market computer software, or related products or services, that are
substantially similar to or competitive with any computer software, or related
products or services, the creation, development, sale, licensing or other
marketing of which he participated in during Shareholder's employment with
Carreker; or

           (c)  Divulge, transmit or otherwise disclose or cause to be
divulged, transmitted or otherwise disclosed, any business contacts, client or
customer lists, technology, know-how, trade secrets, marketing techniques,
contracts or other confidential or proprietary information of Carreker and its
subsidiaries of whatever nature, whether existing on or prior to the date of
this Agreement or arising from and after the date of this Agreement (provided,
however, that for purposes of this Agreement, information (other than client or
customer lists) shall not be considered to be confidential or proprietary if (i)
it is a matter of public record, (ii) it is generally known in the industry, or
(iii) the Shareholder can demonstrate that such information was already known to
the recipient thereof other than by reason of any breach of any obligation under
this Agreement or any other confidentiality or non-disclosure agreement); or

           (d)   Recruit, attempt to hire, solicit, assist others in recruiting
or hiring, or refer to others concerning employment, in or with respect to the
geographical areas referred to in Section 2 below, any person who is an employee
of Carreker or any of their subsidiaries or induce or attempt to induce any such
employee to terminate his employment with Carreker or any of its subsidiaries.

      2.   GEOGRAPHICAL AREAS.  The geographical areas in which the
restrictions provided for in this Agreement apply include all cities, counties
and states of the United States, and all other countries, in which Carreker or
Antinori has engaged in licensing or sales or otherwise conducted business or
selling or licensing efforts at any time during the two years prior to the
Effective Date of this Agreement or during the term of this Agreement. 
Shareholder acknowledges that the scope and period of restrictions provided for
in Section 1 and the geographical area to which the 


NONCOMPETITION AGREEMENT - Page 2

<PAGE>

restrictions apply as described in this Section 2 are fair and reasonable and 
are reasonably required for the protection of Carreker and that this 
Agreement accurately describes the business to which the restrictions are 
intended to apply.

      3.   CONSENT TO INJUNCTION.  Shareholder acknowledges that any breach of
the covenants of this Agreement will result in immediate and irreparable injury
to Carreker and, accordingly, consents to the application of injunctive relief
and such other equitable remedies for the benefit of Carreker as may be
appropriate if such a breach occurs or is threatened.  The foregoing remedies
will be in addition to all other legal remedies to which Carreker may be
entitled hereunder, including, without limitation, monetary damages.

supersedes and replaces all prior agreements between Carreker and Shareholder or
Antinori and Shareholder concerning 


NONCOMPETITION AGREEMENT - Page 4

<PAGE>

the subject matter hereof.  This Agreement may not be changed or modified in 
whole or in part except by a writing signed by the party against whom 
enforcement of the change or modification is sought.

           (c)   SUCCESSORS AND ASSIGNS.  This Agreement will not be assignable
by either Shareholder or Carreker, except that the rights and obligations of
Carreker under this Agreement may be assigned to a corporation which becomes the
successor to Carreker as the result of a merger or other corporate
reorganization and which continues the business of Carreker, or any other
subsidiary of Carreker, provided that Carreker guarantees the performance by
such assignee of Carreker's obligations hereunder.

           (d)   GOVERNING LAW.  The laws of the State of Texas (without regard
to its choice of law principles that might apply the law of another
jurisdiction) will govern the validity of this Agreement, the construction of
its terms, and the interpretation and enforcement of the rights and duties of
the parties.

           (e)   NO WAIVER.  The failure of any party to enforce any of the
provisions of this Agreement will not be construed to be a waiver of the right
of such party thereafter to enforce such provisions.  The waiver by any party of
the right to enforce any of the provisions of this Agreement on any occasion
will not be construed to be a waiver of the right of such party to enforce such
provisions on any other occasion.

           (f)   SEVERABILITY.  Shareholder and Carreker recognize that the
limitations contained herein are reasonably and properly required for the
adequate protection of the interests of Carreker.  The intent of the parties is
that the provisions of this Agreement be enforced to the fullest extent
permissible under applicable law.  If for any reason a court of competent
jurisdiction or a binding arbitration proceeding finds any provision or position
of this Agreement or the application thereof, to be invalid or unenforceable,
then this Agreement will be deemed amended to revise that provision or position
to the minimum extent necessary to render it valid and enforceable and the
remaining provisions of this Agreement will be interpreted so as best to
reasonably effect the intent of the parties.

           (g)   COUNTERPARTS.  This Agreement may be executed in counterparts,
each of which will be an original as regards any party whose name appears
thereon and all of which together will constitute one and the same instrument. 
This Agreement will become binding when one or more counterparts hereof,
individually or taken together, bear the signatures of both parties reflected
hereon as signatories.

           (h)   EFFECT OF AGREEMENT.  This Agreement will be void and have no
effect if the Effective Date does not occur on or before February 1, 1997.

           (i)   DISPUTE RESOLUTION.


NONCOMPETITION AGREEMENT - Page 5

<PAGE>

                 (i)     ARBITRATION OF DISPUTES.  Any dispute under this
Agreement shall be resolved by arbitration in Dallas, Texas and, except as
herein specifically stated, in accordance with the commercial arbitration rules
of the American Arbitration Association ("AAA RULES") then in effect.  However,
in all events, these arbitration provisions shall govern over any conflicting
rules that may now or hereafter be contained in the AAA Rules.  Any judgment
upon the award rendered by the arbitrator may be entered in any court having
jurisdiction over the subject matter thereof.  The arbitrator shall have the
authority to grant any equitable and legal remedies that would be available in
any judicial proceeding instituted to resolve such dispute.

                 (ii)    COMPENSATION OF ARBITRATOR.  Any such arbitration will
be conducted before a single arbitrator who will be compensated for his or her
services at a rate to be determined by the parties or by the American
Arbitration Association, but based upon a reasonable hourly or daily consulting
rate for the arbitrator if the parties are not able to agree upon his or her
compensation.

                 (iii)   SELECTION OF ARBITRATOR.  The American Arbitration
Association will have the authority to select an arbitrator from a list of
arbitrators who are lawyers familiar with Texas contract law and experienced in
mergers and acquisitions; provided, however, that such lawyers cannot work for a
firm then performing services for either party, that each party will have the
opportunity to make such reasonable objection to any of the arbitrators listed
as such party may wish and that the American Arbitration Association will select
the arbitrator from the list of arbitrators as to whom neither party makes any
such objection.  If the foregoing procedure is not followed, then each party
will choose one person from the list of arbitrators provided by the American
Arbitration Association (provided that such person does not have a conflict of
interest), and the two persons so selected will select from the list provided by
the American Arbitration Association the person who will act as the arbitrator.

                 (iv)    PAYMENT OF COSTS.  Carreker and Shareholder will each
pay 50% of the initial compensation to be paid to the arbitrator in any such
arbitration and 50% of the costs of transcripts and other normal and regular
expenses of the arbitration proceedings; provided, however, that the prevailing
party in any arbitration will be entitled to an award of attorneys' fees and
costs, and all costs of arbitration, including those provided for above, will be
paid by the non-prevailing party, and the arbitrator will be authorized to make
such determinations.

                 (v)     BURDEN OF PROOF.  For any dispute submitted to
arbitration, the burden of proof will be as it would be if the claim were
litigated in a Texas judicial proceeding.

                 (vi)    AWARD.  Upon the conclusion of any 


NONCOMPETITION AGREEMENT - Page 6

<PAGE>

arbitration proceedings hereunder, the arbitrator will render findings of 
fact and conclusions of law and a written opinion setting forth the basis and 
reasons for any decision reached and will deliver such documents to each 
party to this Agreement along with a signed copy of the award.

                 (vii)   TERMS OF ARBITRATION.  The arbitrator chosen in
accordance with these provisions will not have the power to alter, amend or
otherwise affect the terms of these arbitration provisions or the provisions of
this Agreement.

                 (viii)  EXCLUSIVE REMEDY.  Except as specifically otherwise
provided in this Agreement (including as provided in Section 3), arbitration
will be the sole and exclusive remedy of the parties for any dispute arising out
of this Agreement.

                                                                    EXHIBIT D-1

                                ESCROW AGREEMENT

      This Escrow Agreement (this "AGREEMENT") is entered into as of January 
31, 1997, among The Carreker Group, Inc., a Texas corporation ("CARREKER"), 
Ronald R. Antinori, Susan Antinori and Michael Israel, who are the 
shareholders (collectively, the "HOLDERS") of Antinori Software, Inc., a 
Georgia corporation ("ANTINORI"), and U.S. Trust Company of Texas, N.A. 
("ESCROW AGENT").

                                    RECITALS

      A.   Antinori, Carreker and a wholly-owned subsidiary of Carreker have 
entered into an Agreement and Plan of Merger dated as of January 29, 1997 
(the "AGREEMENT") pursuant to which Antinori will merge with and into such 
wholly-owned subsidiary of Carreker, with Antinori surviving the merger, such 
that Antinori will become a wholly-owned subsidiary of Carreker.  Capitalized 
terms used in this Agreement and not otherwise defined herein have the 
meanings given them in the Agreement.  A copy of the Agreement has been 
delivered to Escrow Agent.

      B.   Pursuant to the Agreement, an aggregate of 514,614 shares of 
Carreker Class A Voting Common Stock, no par value ("CARREKER COMMON STOCK"), 
are to be issued in the Merger to the Holders.

      C.   The Agreement provides for shares equaling approximately (and less 
than) 5% of the shares of Carreker Common Stock that are issued in the Merger 
(the "ESCROW SHARES") to be deducted from the shares of Carreker Common Stock 
issued to the Holders and placed in an escrow account (the "ESCROW ACCOUNT") 
to secure certain indemnification obligations of the Holders to Carreker and 
the other Indemnified Persons (as defined in Section 10.2 of the Agreement) 
under the Agreement on the terms and conditions set forth herein.  The Escrow 
Shares required to be deposited in the Escrow Account pursuant to this 
Agreement are described on ATTACHMENT A.

      D.   The parties desire to establish the terms and conditions pursuant 
to which the Escrow Shares will be deposited, held in, and disbursed from the 
Escrow Account.

      NOW, THEREFORE, the parties agree as follows:

      1.   ESCROW AND INDEMNIFICATION.
                                       
                                     Page 1
<PAGE>

           (a)   ESCROW OF SHARES.  Promptly after the Effective Time of the 
Merger, Carreker will deposit the Escrow Shares with Escrow Agent, who will 
hold them in escrow as collateral for the indemnification obligations of the 
Holders under Section 10.2 of the Agreement until such time as such Escrow 
Shares are released pursuant to this Agreement.  The Escrow Shares include 
any "ADDITIONAL ESCROW SHARES" as that term is defined in Section 2(b) of 
this Agreement. Escrow Agent agrees to accept delivery of the Escrow Shares 
and to hold the Escrow Shares in escrow subject to the terms and conditions 
of this Agreement.

           (b)   INDEMNIFICATION.  Carreker and the other Indemnified Persons 
are indemnified pursuant to the terms of Section 10.2 of the Agreement (which 
terms are incorporated herein by reference) from and against any Carreker 
Damages, subject to the limitations set forth in Section 10.2 of the 
Agreement and in this Agreement.  (For purposes of this Agreement, references 
to Carreker will include all other Indemnified Persons, as applicable.)   A 
number of Shares equalling approximately (and less than) 5% of the shares of 
Carreker Common Stock that are issued in the Merger to the Holders (the 
"ESCROW SHARES") will be security for this indemnity obligation, subject to 
the limitations, and in the manner provided, in Sections 10.2 of the 
Agreement and this Agreement.  Ronald R. Antinori shall act as Representative 
of the Holders for purposes of this Agreement, is duly authorized to be such 
Representative and may bind the Holders.  Promptly after the receipt by 
Carreker of notice or discovery of any claim, damage or legal action or 
proceeding giving rise to indemnification rights under Section 10.2 of the 
Agreement, Carreker will give the Representative and Escrow Agent written 
notice of such claim, damage, legal action or proceeding (a "CLAIM") in 
accordance with Section 3 of this Agreement. Within seven days of delivery of 
such written notice, the Representative may, with Carreker's written consent, 
which shall not be unreasonably withheld, at the expense of the Holders, 
elect to take all necessary steps properly to contest any Claim involving 
third parties or to prosecute or defend such Claim to conclusion or 
settlement.  If the Representative makes the foregoing election, then the 
Representative will take all necessary steps to contest any such Claim or to 
prosecute or defend such Claim to conclusion or settlement, and will notify 
Carreker of the progress of any such Claim, will permit Carreker, at its 
expense, to participate in such prosecution or defense (PROVIDED, HOWEVER, 
that if a conflict of interest exists which would make it inappropriate, in 
the reasonable opinion of Carreker, for the same counsel to represent both 
Carreker and the Holders in the resolution of such Claim, then Carreker may 
retain separate counsel, the fees and expenses of which shall not be borne by 
Carreker but shall instead be borne by the Holders) and will provide Carreker 
with reasonable access to all relevant information and documents relating to 
the Claim and the Representative's prosecution or defense thereof.  If the 
Representative does not make such election, then Carreker shall be 

                                     Page 2
<PAGE>

free to handle the prosecution or defense of any such Claim, will take all 
necessary steps to contest any such Claim involving third parties or to 
prosecute or defend such Claim to conclusion or settlement, will notify the 
Representative of the progress of any such Claim, and will permit the 
Representative, at the expense of the Holders, to participate in such 
prosecution or defense and will provide the Representative with reasonable 
access to all relevant information and documents relating to the Claim and 
Carreker's prosecution or defense thereof.  In either case, the party not in 
control of a Claim will cooperate with the other party in the conduct of the 
prosecution or defense of such Claim. Neither party will compromise or settle 
any such Claim without the written consent of either Carreker (if the 
Representative defends the Claim) or the Representative (if Carreker defends 
the Claim), such consent not to be unreasonably withheld.

           (c)   LIMITATION ON LIABILITY.  The maximum liability of a Holder 
under Section 10.2 of the Agreement and under this Agreement, and Carreker's 
sole and exclusive remedy under Section 10.2 of the Agreement and under this 
Agreement, will be the number of Escrow Shares set forth next to each such 
Holder's name on ATTACHMENT A; provided, however, that the foregoing 
limitation on liability shall not apply in respect of Ronald R. Antinori's 
indemnity obligations resulting from fraud or intentional and willful 
misrepresentation or intentional and willful concealment.

      2.   DEPOSIT OF ESCROW SHARES; RELEASE FROM ESCROW.

           (a)   DELIVERY OF ESCROW SHARES.  On the Closing Date, the Escrow 
Shares allocable to a Holder (the "INITIAL ESCROW SHARES") will be delivered 
by Carreker to Escrow Agent in the form of duly authorized stock certificates 
issued in the respective names of the Holder thereof together with endorsed 
stock powers.  On the Closing Date, each of the Holders will deliver to 
Carreker a duly endorsed stock power in the form of ATTACHMENT B.  If 
Carreker issues any Additional Escrow Shares (as defined below), then such 
shares will be issued and delivered to Escrow Agent in the same manner as the 
Escrow Shares delivered on the Closing Date.

           (b)   DIVIDENDS, VOTING AND RIGHTS OF OWNERSHIP.  Except for 
tax-free dividends paid in stock declared with respect to the Escrow Shares 
pursuant to Section 305(a) of the Code ("ADDITIONAL ESCROW SHARES") and 
returns of capital, any cash dividends, dividends payable in securities or 
other distributions made in respect of the Escrow Shares will be distributed 
by Carreker to each Holder.  The Holder will have the right to vote the 
Escrow Shares deposited in the Escrow Account for the account of such Holder 
so long as such Escrow Shares are held in escrow, and Carreker will take all 
reasonable steps necessary to allow the exercise of such rights.  While the 
Escrow Shares remain in Escrow Agent's possession pursuant to this Agreement, 
the Holder will retain and will be able to exercise all other incidents of 

                                     Page 3
<PAGE>

ownership of said Escrow Shares that are not inconsistent with the terms and 
conditions of this Agreement.

           (c)   DISTRIBUTIONS TO HOLDERS.  On or before January 31, 1998 
(the "FINAL RELEASE DATE"), Escrow Agent will release from escrow to each 
Holder such Holder's Escrow Shares, plus that portion of all Additional 
Escrow Shares related to the Escrow Shares, less (A) any Escrow Shares 
delivered to Carreker in accordance with Section 4 in satisfaction of Claims 
by Carreker pursuant to Section 1(b) and (B) any Escrow Shares subject to 
delivery to Carreker in accordance with Section 4 with respect to any then 
pending but unresolved Claims of Carreker pursuant to Section 1(b).  Any 
Escrow Shares held as a result of clause (B) will be released to the Holder 
or released to Carreker for cancellation (as appropriate) promptly upon 
resolution of each specific Claim involved.

           (d)   RELEASE OF SHARES.  The Escrow Shares will be held by Escrow 
Agent until required to be released pursuant to Section 2(c) above.  Within 
five business days after the applicable release condition is met, Escrow 
Agent will deliver to the Holders the requisite number of Escrow Shares to be 
released on such date as identified by Carreker and the Representative to 
Escrow Agent in writing.  Such delivery will be in the form of stock 
certificate(s) issued in the names of such Holders.  Carreker and the 
Representative undertake to deliver a timely notice to Escrow Agent 
identifying the number of Escrow Shares to be released within such five-day 
period.  Carreker will take such action as may be necessary to cause stock 
certificates to be issued in the names of the Holders. Escrow Agent will have 
such stock certificates in its possession no later than three business days 
prior to the day on which Escrow Agent is to deliver such certificates to the 
Holders.  Certificates representing Escrow Shares will bear a legend 
indicating that they are subject to resale restrictions.  Cash will be paid 
in lieu of fractions of Escrow Shares in an amount equal to the product 
determined by multiplying such fraction by the per share value of Carreker 
Common Stock as stated in Section 1.2 of the Agreement.  Within five business 
days after written request from the Representative, Carreker will submit a 
certified schedule of the cash amounts payable for fractional shares and will 
deposit with Escrow Agent sufficient funds to pay such cash amounts for 
fractional shares.

           (e)   NO ENCUMBRANCE.  No Escrow Shares or any beneficial interest 
therein may be pledged, sold, assigned or transferred, including by operation 
of law, by a Holder or be taken or reached by any legal or equitable process 
in satisfaction of any debt or other liability of the Holder (other than such 
Holder's obligations under Section 10.2 of the Agreement), prior to the 
delivery to such Holder of the Escrow Shares by Escrow Agent.

           (f)   POWER TO TRANSFER ESCROW SHARES.  Escrow Agent is 

                                     Page 4
<PAGE>

hereby granted the power to effect any transfer of Escrow Shares contemplated 
by this Agreement.  Carreker will cooperate with Escrow Agent in promptly 
issuing stock certificates to effect such transfers.

      3.   NOTICE OF CLAIM.

           (a)   Each notice of a Claim by Carreker pursuant to Section 1(b) 
(the "NOTICE OF CLAIM") will be in writing and will contain the following 
information to the extent reasonably available to Carreker:

                 (i)     Carreker's good faith estimate of the reasonably 
foreseeable maximum amount of the alleged Carreker Damages (which amount may 
be the amount of damages claimed by a third party plaintiff in an action 
brought against Carreker or Antinori based on alleged facts, which if true, 
would constitute a breach of Antinori's representations and warranties); and

                 (ii)    A brief description in reasonable detail of the 
facts, circumstances or events giving rise to the alleged Carreker Damages 
based on Carreker's good faith belief thereof, including, without limitation, 
the identity and address of any third-party claimant (to the extent 
reasonably available to Carreker) and copies of any formal demand or 
complaint.

           (b)   Escrow Agent will not transfer any of the Escrow Shares held 
in the Escrow Account to Carreker pursuant to a Notice of Claim until such 
Notice of Claim has been resolved in accordance with Section 4.

      4.   RESOLUTION OF NOTICE OF CLAIM AND TRANSFER OF ESCROW SHARES.  Any 
Notice of Claim received by the Representative and Escrow Agent pursuant to 
Section 3, or any notice of a claim received by the Representative and Escrow 
Agent pursuant to Section 1(c) (a "LIQUIDATED DAMAGES CLAIM"), will be 
resolved as follows:

           (a)   UNCONTESTED CLAIMS.  If the Representative does not contest 
a Notice of Claim or a Liquidated Damages Claim in writing to Escrow Agent 
and Carreker and the Representative does not pay the amount demanded within 
15 calendar days after the Notice of Claim or the Liquidated Damages Claim is 
delivered pursuant to Section 4(b) below, then Escrow Agent will immediately 
transfer to Carreker for cancellation that number of the Escrow Shares having 
a value (determined pursuant to Section 4(c)) equal to the amount of Carreker 
Damages specified in the Notice of Claim, or the amount of the Liquidated 
Damages (in the case of a Liquidated Damages Claim), which number will be 
allocated among the Holders in proportion to their percentage interests in 
the Escrow Shares set forth on ATTACHMENT A, and will notify the 
Representative of such transfer.

                                     Page 5
<PAGE>

           (b)   CONTESTED CLAIMS.  To recover Claims under this Escrow it 
will not be necessary to institute an arbitration proceeding pursuant to 
Section 11.1 of the Agreement; the arbitrator hereunder being authorized to 
determine the existence of Claims, as well as the amount of Carreker Damages 
(in the case of a Claim under Section 1(b) above) associated therewith.  If 
the Representative gives written notice contesting all, or a portion of, a 
Notice of Claim or Liquidated Damages Claim to Carreker and Escrow Agent (a 
"CONTESTED CLAIM") within the 15-day period provided above, then matters that 
are subject to a third party claim brought against Carreker or Antinori in 
litigation or an arbitration proceeding will await the final decision, award 
or settlement of such litigation or arbitration proceeding, while matters 
that arise between Carreker on the one hand and Antinori on the other hand 
("ARBITRABLE CLAIMS"), will be settled by binding arbitration.  Any portion 
of the Notice of Claim that is not contested will be resolved as set forth 
above in Section 4(a).  The final decision of the arbitrator will be 
furnished to Escrow Agent, the Representative and Carreker in writing and 
will constitute a conclusive determination of the issue in question, binding 
upon the Holders and Carreker.  After notice that the Notice of Claim is 
contested by the Representative, Escrow Agent will continue to hold in the 
Escrow Account Escrow Shares having a value (determined pursuant to Section 
4(c)) sufficient to cover such Claim (notwithstanding the expiration of the 
Final Release Date) until (i) execution of a settlement agreement by Carreker 
and the Representative setting forth a resolution of the Notice of Claim, or 
(ii) receipt of a copy of the final award of the arbitrator.

                 (i)     ARBITRATION.  Any contested Claim shall be settled 
by arbitration in Dallas, Texas, and, except as herein specifically stated, 
in accordance with the commercial arbitration rules of the American 
Arbitration Association ("AAA RULES") then in effect.  However, in all 
events, these arbitration provisions shall govern over any conflicting rules 
that may now or hereafter be contained in the AAA Rules.  Any judgment upon 
the award rendered by the arbitrator may be entered in any court having 
jurisdiction over the subject matter thereof.

                 (ii)    COMPENSATION OF ARBITRATOR.  Any such arbitration 
will be conducted before a single arbitrator who will be compensated for his 
or her services at a rate to be determined by the parties or by the American 
Arbitration Association, but based upon a reasonable hourly or daily 
consulting rate for the arbitrator if the parties are not able to agree upon 
his or her rate of compensation.

                 (iii)   SELECTION OF ARBITRATOR.  The American Arbitration 
Association will have the authority to select an arbitrator from a list of 
lawyers who are familiar with Texas contract law and experienced in mergers 
and acquisitions; provided, however, that such lawyers cannot work for a firm 
then

                                     Page 6
<PAGE>

performing services for either party, that each party will have the 
opportunity to make such reasonable objection to any of the arbitrators 
listed as such party may wish and that the American Arbitration Association 
will select the arbitrator from the list of arbitrators as to whom neither 
party makes any such objection. If the foregoing procedure is not followed, 
then each party will choose one person from the list of arbitrators provided 
by the American Arbitration Association (provided that such person does not 
have a conflict of interest), and the two persons so selected will select 
from the list provided by the American Arbitration Association the person who 
will act as the arbitrator.

                 (iv)    PAYMENT OF COSTS.  Carreker and the Holders will 
each pay 50% of the initial compensation to be paid to the arbitrator in any 
such arbitration and 50% of the costs of transcripts and other normal and 
regular expenses of the arbitration proceedings; provided, however, that the 
prevailing party in any arbitration will be entitled to an award of 
attorneys' fees and costs, and all costs of arbitration, including those 
provided for above, will be paid by the non-prevailing party, and the 
arbitrator will be authorized to make such determinations.  At Carreker's 
option, the Holders' liability for such fees and costs and costs of 
arbitration may be paid by Carreker and recovered by Carreker as a Claim 
hereunder out of the Escrow Shares.

                 (v)     BURDEN OF PROOF.  For any Arbitrable Claim submitted 
to arbitration, the burden of proof will be as it would be if the claim were 
litigated in a Texas judicial proceeding.

                 (vi)    AWARD.  Upon the conclusion of any arbitration 
proceedings hereunder, the arbitrator will render findings of fact and 
conclusions of law and a written opinion setting forth the basis and reasons 
for any decision reached and will deliver such documents to each party to 
this Agreement along with a signed copy of the award.  In the case of an 
award pursuant to a Liquidated Damages Claim, the amount of the award will be 
equal to the Liquidated Damages plus costs of arbitration as provided above.

                 (vii)   TERMS OF ARBITRATION.  The arbitrator chosen in 
accordance with these provisions will not have the power to alter, amend or 
otherwise affect the terms of these arbitration provisions or the provisions 
of this Agreement or the Agreement.  

                 (viii)  EXCLUSIVE REMEDY.  Except as specifically otherwise 
provided in this Agreement or the Agreement, arbitration will be the sole and 
exclusive remedy of the parties for any Arbitrable Claim arising out of this 
Agreement.

           (c)   DETERMINATION OF AMOUNT OF CLAIMS.  Any amount owed to 
Carreker hereunder, determined pursuant to Section 4(a) or 

                                     Page 7
<PAGE>

(b) above, will be immediately payable to Carreker out of the Escrow Shares 
then held by Escrow Agent on a pro rata basis among the Holders at a per 
share value for all Escrow Shares equal to $23.83.

           (d)   NO EXHAUSTION OF REMEDIES. Carreker need not exhaust any 
other remedies that may be available to it but may proceed directly in 
accordance with the provisions of this Agreement.  Carreker may institute 
Claims against the Escrow Shares and in satisfaction thereof may recover 
Escrow Shares, in accordance with the terms of this Agreement, without making 
any other Claims directly against the Holders and without rescinding or 
attempting to rescind the transactions consummated pursuant to the Agreement. 
The assertion of any single Claim for indemnification hereunder will not bar 
Carreker from asserting other Claims hereunder.

      5.   LIMITATION OF ESCROW AGENT'S LIABILITY.

           (a)   Escrow Agent will incur no liability with respect to any 
action taken or suffered by it in reliance upon any notice, direction, 
instruction, consent, statement or other document believed by it to be 
genuine and duly authorized, nor for any other action or inaction, except its 
own willful misconduct or gross negligence.  Escrow Agent shall have no duty 
to inquire into or investigate the validity, accuracy or content or any 
document delivered to it.  Escrow Agent will not be responsible for the 
validity or sufficiency of this Agreement.  In all questions arising under 
this Agreement, Escrow Agent may rely on the advice or opinion of counsel, 
and for anything done, omitted or suffered in good faith by Escrow Agent 
based on such advice, Escrow Agent will not be liable to anyone.  Escrow 
Agent will not be required to take any action hereunder involving its expense 
unless the payment of such expense is made or provided for in a manner 
satisfactory to it.

           (b)   If conflicting demands are made or conflicting notices are 
served upon Escrow Agent with respect to the Escrow Account, then Escrow 
Agent will have the absolute right, at Escrow Agent's election, to do either 
or both of the following:  (i) resign so a successor can be appointed 
pursuant to Section 9 or (ii) file a suit in interpleader and obtain an order 
from a court of competent jurisdiction requiring the parties to interplead 
and litigate in such court their several claims and rights among themselves.  
If such interpleader suit is brought, then Escrow Agent will thereby be fully 
released and discharged from all further obligations imposed upon it under 
this Agreement, and Carreker and the Holders will each pay Escrow Agent 50% 
percent of all costs, expenses and reasonable attorney's fees expended or 
incurred by Escrow Agent pursuant to the exercise of Escrow Agent's rights 
under this Section 5 (such costs, fees and expenses being treated as 
extraordinary fees and expenses for the purposes of Section 8); provided, 
however, that Carreker and the Holders 

                                     Page 8
<PAGE>

shall be entitled to reimbursement from the Holders and Carreker, 
respectively, of any extraordinary fees and expenses of Escrow Agent paid by 
Carreker and the Holders, respectively, if Carreker or the Holders, 
respectively, prevails in the resolution of such claims and rights, in 
accordance with Section 8.

           (c)   Each party hereto other than Escrow Agent, jointly and 
severally (each an "INDEMNIFYING PARTY" and together the "INDEMNIFYING 
PARTIES"), hereby covenants and agrees to reimburse, indemnify and hold 
harmless Escrow Agent, Escrow Agent's officers, directors, employees, counsel 
and agents (severally and collectively, "ESCROW AGENT"), from and against any 
loss, damage, liability or loss suffered, incurred by, or asserted against 
Escrow Agent (including amounts paid in settlement of any action, suit, 
proceeding, or claim brought or threatened to be brought and including 
reasonable expenses of legal counsel) arising out of, in connection with or 
based upon any act or omission by Escrow Agent (and/or any of its officers, 
directors, employees, counsel or agents) relating in any way to this 
Agreement or Escrow Agent's services hereunder.  This indemnity shall exclude 
gross negligence and willful misconduct on Escrow Agent's part.  Anything in 
this Agreement to the contrary notwithstanding, Escrow Agent shall not be 
liable for special, indirect or consequential loss or damage of any kind 
(including but not limited to lost profits), even if Escrow Agent has been 
advised of the likelihood of such loss or damage and regardless of the form 
of action.

           (d)   Each Indemnifying Party may participate at its own expense 
in the defense of any claim or action that may be asserted against Escrow 
Agent, and if the Indemnifying Parties so elect, the Indemnifying Parties may 
assume the defense of such claim or action; PROVIDED, HOWEVER, that if a 
conflict of interest exists that would make it inappropriate, in the sole 
discretion of Escrow Agent, for the same counsel to represent both Escrow 
Agent and the Indemnifying Parties, then Escrow Agent's retention of separate 
counsel shall be reimbursable as herein above provided.  Escrow Agent's right 
to indemnification hereunder shall survive Escrow Agent's resignation or 
removal as Escrow Agent and shall survive the termination of this Agreement 
by lapse of time or otherwise.

           (e)   Escrow Agent hereby warrants that Escrow Agent will notify 
each Indemnifying Party by letter, or by telephone or telecopy confirmed by 
letter, of any receipt by Escrow Agent of a written assertion of a claim 
against Escrow Agent, or any action commenced against Escrow Agent, within 
three business days after Escrow Agent's receipt of written notice of such 
claim. However, Escrow Agent's failure to notify each Indemnifying Party 
shall not operate to relieve an Indemnifying Party from any liability that it 
may have on account of this Section 5 unless such failure prejudices such 
Indemnifying Party's rights.

           (f)   Escrow Agent may execute any of its powers or 
responsibilities hereunder and exercise any rights hereunder 

                                     Page 9
<PAGE>

either directly or by or through its agents or attorneys.  Nothing in this 
Agreement shall be deemed to impose upon Escrow Agent any duty to qualify to 
do business or to act as a fiduciary or otherwise in any jurisdiction other 
than the State of Texas.

      6.   NOTICES.  All notices, instructions and other communications 
required or permitted to be given hereunder or necessary or convenient in 
connection herewith shall be in writing and will be deemed delivered (i) when

      7.   GENERAL.

           (a)   GOVERNING LAW, ASSIGNS.  The laws of the State of Texas 
(without regard to its choice of law principles that might apply the law of 
another jurisdiction) will govern the validity of this Agreement, the 
construction of its terms, and the interpretation and enforcement of the 
rights and duties of the parties.  This Agreement will be binding upon and 
inure to the benefit of the parties and their respective successors and 
permitted assigns.

           (b)   COUNTERPARTS.  This Agreement may be executed in 
counterparts, each of which will be an original as regards any party whose 
name appears thereon and all of which together will constitute one and the 
same instrument. This Agreement will become binding when one or more 
counterparts hereof, individually or taken together, bear the signatures of 
all parties reflected hereon as signatories.

           (c)   ENTIRE AGREEMENT.  Except as otherwise set forth in the 
Agreement, this Agreement constitute the entire understanding and agreement 
of the parties with respect to the subject matter of this Agreement and 
supersedes all prior agreements or understandings, written or oral, between 
the parties with respect to the subject matter hereof.

           (d)   WAIVERS.  No waiver by any party of any condition or of any 
breach of any provision of this Agreement will be effective unless in 
writing. No waiver by any party of any such condition or breach, in any one 
instance, will be deemed to be a further or continuing waiver of any such 
condition or breach or a waiver of any other condition or breach of any other 
provision contained herein.

           (e)   TAX IDENTIFICATION NUMBERS.  Each party, other than Escrow 
Agent, shall provide Escrow Agent with its Tax Identification Number (TIN) as 
assigned by the Internal Revenue Service.

      8.   EXPENSES OF ESCROW AGENT.  All fees and expenses of Escrow Agent 
incurred in the ordinary course of performing its responsibilities hereunder 
will be paid 50% by Carreker and 50% by 

                                     Page 11
<PAGE>

the Holders, upon receipt of a written invoice from Escrow Agent.  Any 
extraordinary fees and expenses, including without limitation any fees or 
expenses (including the fees or expenses of counsel to Escrow Agent) incurred 
by Escrow Agent in connection with a dispute over the distribution of Escrow 
Shares or the validity of a Notice of Claim, will be paid 50% by Carreker and 
50% by the Holders upon receipt of a written invoice by Escrow Agent; 
provided, however, that Carreker and the Holders shall be entitled to 
reimbursement from the Holders and Carreker, respectively, of any 
extraordinary fees and expenses of Escrow Agent paid by Carreker and the 
Holders, respectively, if Carreker or the Holders, respectively, prevails in 
such dispute.

      9.   SUCCESSOR ESCROW AGENT.  If Escrow Agent becomes unavailable or 
unwilling to continue in its capacity herewith, then Escrow Agent may resign 
and be discharged from its duties or obligations hereunder by giving notice 
of its resignation to the parties to this Agreement, specifying a date not 
less than ten days following such notice date of when such resignation will 
take effect. Carreker will designate a successor Escrow Agent prior to the 
expiration of such ten-day period by giving written notice to Escrow Agent 
and the Representative. Carreker may appoint an successor Escrow Agent 
without the consent of the Representative so long as such successor is a bank 
or trust company that, together with any parent, has assets of at least $100 
million, and may appoint any other successor Escrow Agent with the consent of 
the Representative, which will not be unreasonably withheld.  Escrow Agent 
will promptly transfer the Escrow Shares to such designated successor.

      10.  LIMITATION OF RESPONSIBILITY.  Escrow Agent's duties are limited 
to those set forth in this Agreement, and Escrow Agent, acting as such under 
this Agreement, is not charged with knowledge of any duties or 
responsibilities under any other document or agreement, including, without 
limitation, the Agreement. Escrow Agent shall not be responsible for the 
validity, binding effect, execution or sufficiency of this Escrow Agreement 
or of any agreement amendatory or supplemental hereto.

      11.  AMENDMENT.  This Agreement may be amended by the written agreement 
of Carreker, Escrow Agent and the Representative, provided that, if Escrow 
Agent does not agree to an amendment agreed upon by Carreker and the 
Representative, then Escrow Agent will resign and Carreker will appoint a 
successor Escrow Agent in accordance with Section 9.  No amendment of the 
Agreement shall increase Escrow Agent's responsibilities or liability 
hereunder without Escrow Agent's written agreement.

      12.  HOLDER'S REPRESENTATIVE.  For purposes of this Agreement, the 
Holders hereby consent to the appointment of the Representative, as 
representative of the Holders, and as the attorney-in-fact for and on behalf 
of each Holder, and, subject to the express limitation set forth below, the 
taking by the 

                                     Page 12
<PAGE>

Representative of any and all actions and the making of any decisions 
required or permitted to be taken by the Representative under this Agreement, 
including, without limitation, the exercise of the power to (i) authorize 
delivery to Carreker of the Escrow Shares, or any portion thereof, in 
satisfaction of any Claims, (ii) agree to, negotiate, enter into settlements 
and compromises of, and demand arbitration and comply with orders of courts 
and awards of arbitrators with respect to any Claims, (iii) resolve any 
Claims, and (iv) take all actions necessary in the judgment of the 
Representative for the accomplishment of the foregoing and all of the other 
terms, conditions and limitations of this Agreement.  The Representative will 
have unlimited authority and power to act on behalf of each Holder with 
respect to this Agreement and the disposition, settlement or other handling 
of all Claims, rights or obligations arising under this Agreement so long as 
all Holders are treated in the same manner.  The Holders will be bound by all 
actions taken by the Representative in connection with this Agreement, and 
Carreker will be entitled to rely on any action or decision of the 
Representative.  In performing the functions specified in this Agreement, the 
Representative will not be liable to the Holders in the absence of gross 
negligence or willful misconduct.  The Representative may resign from such 
position, effective upon a new representative being appointed in writing by 
Holders who beneficially own a majority of the Escrow Shares.  The 
Representative will not be entitled to receive any compensation from Carreker 
or the Holders in connection with this Agreement.  Any out-of-pocket costs 
and expenses reasonably incurred by the Representative in connection with 
actions taken pursuant to the terms of this Agreement will be paid by the 
Holders to the Representative in proportion to their percentage interests in 
the Escrow Shares as set forth on ATTACHMENT A.

      IN WITNESS WHEREOF, the parties have duly executed this Agreement as of 
the day and year first above written.

                                                                    EXHIBIT D-2

                                ESCROW AGREEMENT

     This Escrow Agreement (this "AGREEMENT") is entered into as of January 
31, 1997, among The Carreker Group, Inc., a Texas corporation (the 
"COMPANY"), J.D. Carreker ("HOLDER"), the principal shareholder of the 
Company, and U.S. Trust Company of Texas, N.A. ("ESCROW AGENT").

                                    RECITALS

     A.    Antinori Software, Inc., a Georgia corporation ("ANTINORI"), the 
Company and a wholly-owned subsidiary of the Company have entered into an 
Agreement and Plan of Merger dated as of January 29, 1997 (the "AGREEMENT"), 
pursuant to which Antinori will merge with and into such wholly-owned 
subsidiary, with Antinori surviving the merger, such that Antinori will 
become a wholly-owned subsidiary of the Company.  Capitalized terms used in 
this Agreement and not otherwise defined herein have the meanings given them 
in the Agreement.  A copy of the Agreement has been delivered to Escrow Agent.

     B.    Pursuant to the Agreement, an aggregate of 514,614 shares of the 
Company's Class A Voting Common Stock, no par value ("THE COMPANY COMMON 
STOCK"), are to be issued in the Merger to the shareholders of Antinori.

     C.    The Agreement provides for Holder to place 25,700 shares of 
Company Common Stock, being a number of shares equaling approximately (and 
less than) 5% of the shares of the Company Common Stock that are issued in 
the Merger (the "ESCROW SHARES"), in an escrow account (the "ESCROW ACCOUNT") 
to secure certain indemnification obligations of Holder to the Company and 
the other Indemnified Persons (as defined in Section 10.3 of the Agreement) 
under the Agreement on the terms and conditions set forth herein.

     D.    The parties desire to establish the terms and conditions pursuant 
to which the Escrow Shares will be deposited, held in, and disbursed from the 
Escrow Account.

     NOW, THEREFORE, the parties agree as follows:

     1.    ESCROW AND INDEMNIFICATION.

           (a)   ESCROW OF SHARES.  Promptly after the Effective Time of the 
Merger, Holder will deposit the Escrow Shares with Escrow Agent, who will 
hold them in escrow as collateral for the indemnification obligations of 
Holder under Section 10.3 of the Agreement until such time as such Escrow 
Shares are released 

ESCROW AGREEMENT - Page 1
<PAGE>

pursuant to this Agreement.  The Escrow Shares include any "ADDITIONAL ESCROW 
SHARES" as that term is defined in Section 2(b) of this Agreement.  Escrow 
Agent agrees to accept delivery of the Escrow Shares and to hold the Escrow 
Shares in escrow subject to the terms and conditions of this Agreement.

           (b)   INDEMNIFICATION.  The Company and the other Indemnified 
Persons are indemnified pursuant to the terms of Section 10.3 of the 
Agreement (which terms are incorporated herein by reference) from and against 
any Antinori Damages, subject to the limitations set forth in Section 10.3 of 
the Agreement and in this Agreement.  (For purposes of this Agreement, 
references to the Company will include all other Indemnified Persons, as 
applicable.)  25,700 shares of the Company Common Stock held by Holder (the 
"ESCROW SHARES") will be security for this indemnity obligation, subject to 
the limitations, and in the manner provided, in Sections 10.3 of the 
Agreement and this Agreement.  Promptly after the receipt by the Company of 
notice or discovery of any claim, damage or legal action or proceeding giving 
rise to indemnification rights under Section 10.3 of the Agreement, the 
Company will give Holder and Escrow Agent written notice of such claim, 
damage, legal action or proceeding (a "CLAIM") in accordance with Section 3 
of this Agreement.  Within seven days of delivery of such written notice, 
Holder may, with the Company's written consent, which shall not be 
unreasonably withheld, at the expense of Holder, elect to take all necessary 
steps properly to contest any Claim involving third parties or to prosecute 
or defend such Claim to conclusion or settlement.  If Holder makes the 
foregoing election, then the Holder will take all necessary steps to contest 
any such Claim or to prosecute or defend such Claim to conclusion or 
settlement, and will notify the Company of the progress of any such Claim, 
will permit the Company, at its expense, to participate in such prosecution 
or defense (PROVIDED, HOWEVER, that if a conflict of interest exists which 
would make it inappropriate, in the reasonable opinion of the Company, for 
the same counsel to represent both the Company and Holder in the resolution 
of such Claim, then the Company may retain separate counsel, the fees and 
expenses of which shall not be borne by the Company but shall instead be 
borne by Holder) and will provide the Company with reasonable access to all 
relevant information and documents relating to the Claim and Holder's 
prosecution or defense thereof.  If Holder does not make such election, then 
the Company shall be free to handle the prosecution or defense of any such 
Claim, will take all necessary steps to contest any such Claim involving 
third parties or to prosecute or defend such Claim to conclusion or 
settlement, will notify Holder of the progress of any such Claim, and will 
permit Holder, at his expense, to participate in such prosecution or defense 
and will provide Holder with reasonable access to all relevant information 
and documents relating to the Claim and the Company's prosecution or defense 
thereof.  In either case, the party not in control of a Claim will cooperate 
with the other party in the conduct of the prosecution or defense of such 
Claim.  Neither party will compromise or settle any such Claim without the 
written consent of either the Company (if Holder defends the Claim) or Holder 
(if the Company defends 

ESCROW AGREEMENT - Page 2
<PAGE>

the Claim), such consent not to be unreasonably withheld.

           (c)   LIMITATION ON LIABILITY.  The maximum liability of a Holder 
under Section 10.3 of the Agreement and under this Agreement, and the 
Company's sole and exclusive remedy under Section 10.3 of the Agreement and 
under this Agreement, will be the 25,700 Escrow Shares; provided, however, 
that the foregoing limitation on liability shall not apply in respect of 
Holder's indemnity obligations resulting from fraud or intentional and 
willful misrepresentation or intentional and willful concealment.

     2.    DEPOSIT OF ESCROW SHARES; RELEASE FROM ESCROW.

           (a)   DELIVERY OF ESCROW SHARES.  On the Closing Date, the Escrow 
Shares (the "INITIAL ESCROW SHARES") will be delivered by the Company to 
Escrow Agent in the form of duly authorized stock certificate(s) issued in 
the respective names of Holder together with endorsed stock power(s).  On the 
Closing Date, Holder will deliver to the Company a duly endorsed stock power 
in the form of ATTACHMENT A.  If the Company issues any Additional Escrow 
Shares (as defined below), then such shares will be issued and delivered to 
Escrow Agent in the same manner as the Escrow Shares delivered on the Closing 
Date.

           (b)   DIVIDENDS, VOTING AND RIGHTS OF OWNERSHIP.  Except for 
tax-free dividends paid in stock declared with respect to the Escrow Shares 
pursuant to Section 305(a) of the Code ("ADDITIONAL ESCROW SHARES") and 
returns of capital, any cash dividends, dividends payable in securities or 
other distributions made in respect of the Escrow Shares will be distributed 
by the Company to Holder.  Holder will have the right to vote the Escrow 
Shares deposited in the Escrow Account for the account of Holder so long as 
such Escrow Shares are held in escrow, and the Company will take all 
reasonable steps necessary to allow the exercise of such rights.  While the 
Escrow Shares remain in Escrow Agent's possession pursuant to this Agreement, 
Holder will retain and will be able to exercise all other incidents of 
ownership of said Escrow Shares that are not inconsistent with the terms and 
conditions of this Agreement.

           (c)   DISTRIBUTIONS TO HOLDER.  On or before January 31, 1998 (the 
"FINAL RELEASE DATE"), Escrow Agent will release from escrow to Holder the 
Escrow Shares, plus that portion of all Additional Escrow Shares related to 
the Escrow Shares, less (A) any Escrow Shares delivered to the Company in 
accordance with Section 4 in satisfaction of Claims by the Company pursuant 
to Section 1(b) and (B) any Escrow Shares subject to delivery to the Company 
in accordance with Section 4 with respect to any then pending but unresolved 
Claims of the Company pursuant to Section 1(b).  Any Escrow Shares held as a 
result of clause (B) will be released to Holder or released to the Company 
for cancellation (as appropriate) promptly upon resolution of each specific 
Claim involved.

           (d)   RELEASE OF SHARES.  The Escrow Shares will be held 

ESCROW AGREEMENT - Page 3
<PAGE>

by Escrow Agent until required to be released pursuant to Section 2(c) above. 
Within five business days after the applicable release condition is met, 
Escrow Agent will deliver to Holder the requisite number of Escrow Shares to 
be released on such date as identified by the Company and Holder to Escrow 
Agent in writing.  Such delivery will be in the form of stock certificate(s) 
issued in the names of Holder.  The Company and Holder undertake to deliver a 
timely notice to Escrow Agent identifying the number of Escrow Shares to be 
released within such five-day period.  The Company will take such action as 
may be necessary to cause stock certificates to be issued in the names of 
Holder.  Escrow Agent will have such stock certificates in its possession no 
later than three business days prior to the day on which Escrow Agent is to 
deliver such certificates to Holder.  Certificates representing Escrow Shares 
will bear a legend indicating that they are subject to resale restrictions.  
Cash will be paid in lieu of fractions of Escrow Shares in an amount equal to 
the product determined by multiplying such fraction by the per share value of 
the Company Common Stock as stated in Section 1.2 of the Agreement.  Within 
five business days after written request from Holder, the Company will submit 
a certified schedule of the cash amounts payable for fractional shares and 
will deposit with Escrow Agent sufficient funds to pay such cash amounts for 
fractional shares.

           (e)   NO ENCUMBRANCE.  No Escrow Shares or any beneficial interest 
therein may be pledged, sold, assigned or transferred, including by operation 
of law, by Holder or be taken or reached by any legal or equitable process in 
satisfaction of any debt or other liability of Holder (other than Holder's 
obligations under Section 10.3 of the Agreement), prior to the delivery to 
Holder of the Escrow Shares by Escrow Agent.

           (f)   POWER TO TRANSFER ESCROW SHARES.  Escrow Agent is hereby 
granted the power to effect any transfer of Escrow Shares contemplated by 
this Agreement.  The Company will cooperate with Escrow Agent in promptly 
issuing stock certificates to effect such transfers.

     3.    NOTICE OF CLAIM.

           (a)   Each notice of a Claim by the Company pursuant to Section 
1(b) (the "NOTICE OF CLAIM") will be in writing and will contain the 
following information to the extent reasonably available to the Company:

                 (i)     The Company's good faith estimate of the reasonably 
foreseeable maximum amount of the alleged Antinori Damages (which amount may 
be the amount of damages claimed by a third party plaintiff in an action 
brought against the Company based on alleged facts, which if true, would 
constitute a breach of the Company's representations and warranties); and

                 (ii)    A brief description in reasonable detail of the 
facts, circumstances or events giving rise to the alleged Antinori Damages 
based on the Company's good faith belief thereof, 

ESCROW AGREEMENT - Page 4
<PAGE>

including, without limitation, the identity and address of any third-party 
claimant (to the extent reasonably available to the Company) and copies of 
any formal demand or complaint.

           (b)   Escrow Agent will not transfer any of the Escrow Shares held 
in the Escrow Account to the Company pursuant to a Notice of Claim until such 
Notice of Claim has been resolved in accordance with Section 4.

     4.    RESOLUTION OF NOTICE OF CLAIM AND TRANSFER OF ESCROW SHARES.  Any 
Notice of Claim received by Holder and Escrow Agent pursuant to Section 3, or 
any notice of a claim received by Holder and Escrow Agent pursuant to Section 
1(c) (a "LIQUIDATED DAMAGES CLAIM"), will be resolved as follows:

           (a)   UNCONTESTED CLAIMS.  If Holder does not contest a Notice of 
Claim or a Liquidated Damages Claim in writing to Escrow Agent and the 
Company and Holder does not pay the amount demanded within 15 calendar days 
after the Notice of Claim or the Liquidated Damages Claim is delivered 
pursuant to Section 4(b) below, then Escrow Agent will immediately transfer 
to the Company for cancellation that number of the Escrow Shares having a 
value (determined pursuant to Section 4(c)) equal to the amount of the 
Company Damages specified in the Notice of Claim, or the amount of the 
Liquidated Damages (in the case of a Liquidated Damages Claim), and will 
notify Holder of such transfer.

           (b)   CONTESTED CLAIMS.  To recover Claims under this Escrow it 
will not be necessary to institute an arbitration proceeding pursuant to 
Section 11.1 of the Agreement; the arbitrator hereunder being authorized to 
determine the existence of Claims, as well as the amount of the Company 
Damages (in the case of a Claim under Section 1(b) above) associated 
therewith.  If Holder gives written notice contesting all, or a portion of, a 
Notice of Claim or Liquidated Damages Claim to the Company and Escrow Agent 
(a "CONTESTED CLAIM") within the 15-day period provided above, then matters 
that are subject to a third party claim brought against the Company in 
litigation or an arbitration proceeding will await the final decision, award 
or settlement of such litigation or arbitration proceeding, while matters 
that arise between the Company on the one hand and Antinori on the other hand 
("ARBITRABLE CLAIMS"), will be settled by binding arbitration.  Any portion 
of the Notice of Claim that is not contested will be resolved as set forth 
above in Section 4(a).  The final decision of the arbitrator will be 
furnished to Escrow Agent, Holder and the Company in writing and will 
constitute a conclusive determination of the issue in question, binding upon 
Holder and the Company.  After notice that the Notice of Claim is contested 
by Holder, Escrow Agent will continue to hold in the Escrow Account Escrow 
Shares having a value (determined pursuant to Section 4(c)) sufficient to 
cover such Claim (notwithstanding the expiration of the Final Release Date) 
until (i) execution of a settlement agreement by the Company and Holder 
setting forth a resolution of the Notice of Claim, or (ii) receipt of a copy 
of the final award of the arbitrator.

ESCROW AGREEMENT - Page 5
<PAGE>

                 (i)     ARBITRATION.  Any contested Claim shall be settled 
by arbitration in Dallas, Texas, and, except as herein specifically stated, 
in accordance with the commercial arbitration rules of the American 
Arbitration Association ("AAA RULES") then in effect.  However, in all 
events, these arbitration provisions shall govern over any conflicting rules 
that may now or hereafter be contained in the AAA Rules.  Any judgment upon 
the award rendered by the arbitrator may be entered in any court having 
jurisdiction over the subject matter thereof.

                 (ii)    COMPENSATION OF ARBITRATOR.  Any such arbitration 
will be conducted before a single arbitrator who will be compensated for his 
or her services at a rate to be determined by the parties or by the American 
Arbitration Association, but based upon a reasonable hourly or daily 
consulting rate for the arbitrator if the parties are not able to agree upon 
his or her rate of compensation.

                 (iii)   SELECTION OF ARBITRATOR.  The American Arbitration 
Association will have the authority to select an arbitrator from a list of 
lawyers who are familiar with Texas contract law and experienced in mergers 
and acquisitions; provided, however, that such lawyers cannot work for a firm 
then performing services for either party, that each party will have the 
opportunity to make such reasonable objection to any of the arbitrators 
listed as such party may wish and that the American Arbitration Association 
will select the arbitrator from the list of arbitrators as to whom neither 
party makes any such objection. If the foregoing procedure is not followed, 
then each party will choose one person from the list of arbitrators provided 
by the American Arbitration Association (provided that such person does not 
have a conflict of interest), and the two persons so selected will select 
from the list provided by the American Arbitration Association the person who 
will act as the arbitrator.

                 (iv)    PAYMENT OF COSTS.  The Company and Holder will each 
pay 50% of the initial compensation to be paid to the arbitrator in any such 
arbitration and 50% of the costs of transcripts and other normal and regular 
expenses of the arbitration proceedings; provided, however, that the 
prevailing party in any arbitration will be entitled to an award of 
attorneys' fees and costs, and all costs of arbitration, including those 
provided for above, will be paid by the non-prevailing party, and the 
arbitrator will be authorized to make such determinations.  At the Company's 
option, Holder's liability for such fees and costs and costs of arbitration 
may be paid by the Company and recovered by the Company as a Claim hereunder 
out of the Escrow Shares.

                 (v)     BURDEN OF PROOF.  For any Arbitrable Claim submitted 
to arbitration, the burden of proof will be as it would be if the claim were 
litigated in a Texas judicial proceeding.

                 (vi)    AWARD.  Upon the conclusion of any 

ESCROW AGREEMENT - Page 6
<PAGE>

arbitration proceedings hereunder, the arbitrator will render findings of 
fact and conclusions of law and a written opinion setting forth the basis and 
reasons for any decision reached and will deliver such documents to each 
party to this Agreement along with a signed copy of the award.  In the case 
of an award pursuant to a Liquidated Damages Claim, the amount of the award 
will be equal to the Liquidated Damages plus costs of arbitration as provided 
above.

                 (vii)   TERMS OF ARBITRATION.  The arbitrator chosen in 
accordance with these provisions will not have the power to alter, amend or 
otherwise affect the terms of these arbitration provisions or the provisions 
of this Agreement or the Agreement.

                 (viii)  EXCLUSIVE REMEDY.  Except as specifically otherwise 
provided in this Agreement or the Agreement, arbitration will be the sole and 
exclusive remedy of the parties for any Arbitrable Claim arising out of this 
Agreement.

           (c)   DETERMINATION OF AMOUNT OF CLAIMS.  Any amount owed to the 
Company hereunder, determined pursuant to Section 4(a) or (b) above, will be 
immediately payable to the Company out of the Escrow Shares then held by 
Escrow Agent at a per share value for all Escrow Shares equal to $23.83.

           (d)   NO EXHAUSTION OF REMEDIES.  The Company need not exhaust any 
other remedies that may be available to it but may proceed directly in 
accordance with the provisions of this Agreement.  The Company may institute 
Claims against the Escrow Shares and in satisfaction thereof may recover 
Escrow Shares, in accordance with the terms of this Agreement, without making 
any other Claims directly against Holder and without rescinding or attempting 
to rescind the transactions consummated pursuant to the Agreement.  The 
assertion of any single Claim for indemnification hereunder will not bar the 
Company from asserting other Claims hereunder.









ESCROW AGREEMENT - Page 7
<PAGE>

     5.    LIMITATION OF ESCROW AGENT'S LIABILITY.

           (a)   Escrow Agent will incur no liability with respect to any 
action taken or suffered by it in reliance upon any notice, direction, 
instruction, consent, statement or other document believed by it to be 
genuine and duly authorized, nor for any other action or inaction, except its 
own willful misconduct or gross negligence.  Escrow Agent shall have no duty 
to inquire into or investigate the validity, accuracy or content or any 
document delivered to it.  Escrow Agent will not be responsible for the 
validity or sufficiency of this Agreement.  In all questions arising under 
this Agreement, Escrow Agent may rely on the advice or opinion of counsel, 
and for anything done, omitted or suffered in good faith by Escrow Agent 
based on such advice, Escrow Agent will not be liable to anyone.  Escrow 
Agent will not be required to take any action hereunder involving its expense 
unless the payment of such expense is made or provided for in a manner 
satisfactory to it.

           (b)   If conflicting demands are made or conflicting notices are 
served upon Escrow Agent with respect to the Escrow Account, then Escrow 
Agent will have the absolute right, at Escrow Agent's election, to do either 
or both of the following:  (i) resign so a successor can be appointed 
pursuant to Section 9 or (ii) file a suit in interpleader and obtain an order 
from a court of competent jurisdiction requiring the parties to interplead 
and litigate in such court their several claims and rights among themselves.  
If such interpleader suit is brought, then Escrow Agent will thereby be fully 
released and discharged from all further obligations imposed upon it under 
this Agreement, and the Company and Holder will each pay Escrow Agent 50% 
percent of all costs, expenses and reasonable attorney's fees expended or 
incurred by Escrow Agent pursuant to the exercise of Escrow Agent's rights 
under this Section 5 (such costs, fees and expenses being treated as 
extraordinary fees and expenses for the purposes of Section 8); provided, 
however, that the Company and Holder shall be entitled to reimbursement from 
Holder and the Company, respectively, of any extraordinary fees and expenses 
of Escrow Agent paid by the Company and Holder, respectively, if the Company 
or Holder, respectively, prevails in the resolution of such claims and 
rights, in accordance with Section 8.

           (c)   Each party hereto other than Escrow Agent, jointly and 
severally (each an "INDEMNIFYING PARTY" and together the "INDEMNIFYING 
PARTIES"), hereby covenants and agrees to reimburse, indemnify and hold 
harmless Escrow Agent, Escrow Agent's officers, directors, employees, counsel 
and agents (severally and collectively, "ESCROW AGENT"), from and against any 
loss, damage, liability or loss suffered, incurred by, or asserted against 
Escrow Agent (including amounts paid in settlement of any action, suit, 
proceeding, or claim brought or threatened to be brought and including 
reasonable expenses of legal counsel) arising out of, in connection with or 
based upon any act or omission by Escrow Agent (and/or any of its officers, 
directors, employees, counsel or agents) relating in any way to this 
Agreement or Escrow Agent's 

ESCROW AGREEMENT - Page 8
<PAGE>

services hereunder.  This indemnity shall exclude gross negligence and 
willful misconduct on Escrow Agent's part.  Anything in this Agreement to the 
contrary notwithstanding, Escrow Agent shall not be liable for special, 
indirect or consequential loss or damage of any kind (including but not 
limited to lost profits), even if Escrow Agent has been advised of the 
likelihood of such loss or damage and regardless of the form of action.

           (d)   Each Indemnifying Party may participate at its own expense 
in the defense of any claim or action that may be asserted against Escrow 
Agent, and if the Indemnifying Parties so elect, the Indemnifying Parties may 
assume the defense of such claim or action; PROVIDED, HOWEVER, that if a 
conflict of interest exists that would make it inappropriate, in the sole 
discretion of Escrow Agent, for the same counsel to represent both Escrow 
Agent and the Indemnifying Parties, then Escrow Agent's retention of separate 
counsel shall be reimbursable as herein above provided.  Escrow Agent's right 
to indemnification hereunder shall survive Escrow Agent's resignation or 
removal as Escrow Agent and shall survive the termination of this Agreement 
by lapse of time or otherwise.

           (e)   Escrow Agent hereby warrants that Escrow Agent will notify 
each Indemnifying Party by letter, or by telephone or telecopy confirmed by 
letter, of any receipt by Escrow Agent of a written assertion of a claim 
against Escrow Agent, or any action commenced against Escrow Agent, within 
three business days after Escrow Agent's receipt of written notice of such 
claim. However, Escrow Agent's failure to notify each Indemnifying Party 
shall not operate to relieve an Indemnifying Party from any liability that it 
may have on account of this Section 5 unless such failure prejudices such 
Indemnifying Party's rights.

           (f)   Escrow Agent may execute any of its powers or 
responsibilities hereunder and exercise any rights hereunder either directly 
or by or through its agents or attorneys.  Nothing in this Agreement shall be 
deemed to impose upon Escrow Agent any duty to qualify to do business or to 
act as a fiduciary or otherwise in any jurisdiction other than the State of 
Texas.

     6.    NOTICES.  All notices, instructions and other communications 
required or permitted to be given hereunder or necessary or convenient in 
connection herewith shall be in writing and will be deemed delivered (i) when 
personally served or when delivered by facsimile (to the facsimile number of 
the person to whom notice is given), (ii) the first business day following 
the date of deposit with an overnight courier service or (iii) on the earlier 
of actual receipt or the third business day following the date on which the 
notice is deposited in the United States Mail, first class certified, postage 
prepaid, addressed as follows:

supersedes all prior agreements or understandings, written or oral, between 
the parties with respect to the subject matter hereof.

breach of any provision of this Agreement will be effective unless in

dispute over the distribution of Escrow Shares or the validity of a Notice of 
Claim, will be paid 50% by the Company and 50% by Holder upon receipt of a

will not be unreasonably withheld.  Escrow Agent will promptly transfer the 
Escrow Shares to such designated successor.

Agent will resign and the Company will appoint a successor Escrow Agent in 
accordance with Section 9.  No amendment of the Agreement shall increase 
Escrow Agent's responsibilities or liability hereunder without Escrow Agent's 
written agreement.

                    CERTIFICATE OF ANTINORI SOFTWARE, INC.
                        (RE TAX-FREE REORGANIZATION)

     Antinori Software, Inc., a Georgia corporation ("ANTINORI"), hereby 
represents, in connection with the proposed merger (the "MERGER") of CAG 
Newco, Inc., a Texas corporation and a wholly-owned subsidiary of The 
Carreker Group, Inc., also a Texas corporation ("CARREKER"), into Antinori 
and related transactions set forth under that certain Agreement and Plan of 
Merger dated January 29, 1997 among Carreker, Antinori and CAG Newco, Inc. 
(the "AGREEMENT"), with Antinori surviving the Merger and becoming a 
wholly-owned subsidiary of Carreker, that the following statements are true 
as of the date of this certificate is executed and that the statements will 
be true as of the effective date of the Merger unless the undersigned 
provides a written statement to the contrary prior to the effective date of 
the Merger:

     A.    Antinori's principal reasons for participating in the Merger are 
bona fide business reasons.

     B.    The total fair market value of all consideration other than 
Carreker Class A Voting Common Stock, no par value (the "CARREKER COMMON 
STOCK"), received by Antinori's shareholders in exchange for their Antinori 
Common Stock in the Merger (including, without limitation, cash paid in lieu 
of a fractional shares) will be less than ten percent (10%) of the aggregate 
fair market value of Antinori Common Stock outstanding immediately prior to 
the Merger.

     C.    The payment of cash by Carreker in lieu of issuing fractional 
shares of Carreker Common Stock does not represent separately bargained for 
consideration.

     D.    Except with respect to payments of cash in lieu of fractional 
shares of Carreker Common Stock, one hundred percent (100%) of the Antinori 
Common Stock outstanding immediately prior to the Merger will be exchanged 
solely for Carreker Common Stock.  Thus, except as set forth in the preceding 
sentence, Antinori intends that no consideration be paid or received 
(directly or indirectly, actually or constructively) for Antinori Common 
Stock other than Carreker Common Stock.

     E.    To the best knowledge of Antinori there is no plan or intention on 
the part of the Antinori shareholders (a "PLAN") to sell, exchange, transfer, 
distribute, pledge, or otherwise dispose of (a "SALE") (a) shares of the 
Carreker Common Stock to be issued to Antinori shareholders in the Merger, 
which shares would have an aggregate fair market value, as of the Effective 
Time (as defined in the Agreement) of the Merger, in excess of fifty percent 
(50%) of the aggregate fair market value, immediately prior to the Merger, of 
all outstanding shares of Antinori Common Stock, or (b) more than fifty 
percent (50%) of the shares of Carreker Common Stock to be received in 
exchange for Antinori Common Stock in the Merger.  For purposes of this 
representation, shares of Antinori Common Stock (or the portion thereof) (i) 
with respect to which Antinori shareholders received consideration in the 
Merger other than Carreker Common Stock (including, without limitation, cash 
received in lieu of fractional shares of Carreker Common Stock) and/or (ii) 
with respect to which a Sale occurs during the period ending at the Effective 
Time of the Merger and beginning with the commencement of negotiations 
(whether formal or informal) between Antinori and Carreker regarding the 
Merger (the "Pre-Merger Period"), shall be considered shares of outstanding 
Antinori Common Stock exchanged for Carreker Common Stock in the Merger and 
then disposed of pursuant to a Plan.

     F.    Antinori has not disposed of any assets (other than in the 
ordinary course of business) or, except for a dividend consistent with past 
practice, all or a portion of the proceeds of which will be used to discharge 
tax liabilities resulting from share ownership, declared a dividend as part 
of or in contemplation of the Merger except in accordance with and as 
required by Antinori's Article of Incorporation.

     G.    The liabilities, if any, of Antinori assumed by operation of law 
by CAG Newco, 
                                       
                                     Page 1
<PAGE>

Inc., and the liabilities, if any, to which the transferred assets of 
Antinori are subject, were incurred by Antinori in the ordinary course of 
business or to provide working capital.

     H.    No intercorporate indebtedness exists between Carreker and 
Antinori that was issued or acquired at a discount or which will be settled 
at a discount.

     I.    During the Pre-Merger Period, no indebtedness or other obligation 
of Antinori has been or will be guaranteed by any shareholder of Antinori (or 
any person or entity related to a shareholder of Antinori).

     J.    Antinori will pay its own expenses, if any, incurred in connection 
with the Merger; provided, however that to the extent any expenses relating 
to the Merger (or the "plan of reorganization" within the meaning of Treas.  
Reg. Section 1.368-1(c) with respect to the Merger) are funded directly or 
indirectly by a party other than the incurring party, then such expenses will 
be within the guidelines established in Rev. Rul. 73-54. 1973-1 C.B. 187.

     K.    To the best knowledge of the management of Antinori, neither 
Carreker nor CAG Newco, Inc. will assume any liabilities of any Antinori 
shareholder in connection with the Merger.

     L.    Antinori is not an investment company as defined in Section 
368(a)(2)(F) of the Internal Revenue Code of 1986, as amended.

     M.    The fair market value of the assets of Antinori transferred to CAG 
Newco, Inc. will equal or exceed the sum of the liabilities assumed by CAG 
Newco, Inc., plus the amount of liability, if any, to which the transferred 
assets are subject.

     N.    The terms of the Agreement and all other agreements entered into 
pursuant thereto are the product of arm's-length negotiations.

     O.    None of the compensation payments received by any shareholder of 
Antinori will be separate consideration for, or allocable to, any of their 
shares of Antinori Common Stock.  None of the shares of Carreker Common Stock 
received by any shareholder of Antinori will be separate consideration for, 
or allocable to, any employment agreement, consulting agreement, any 
covenants not to compete or otherwise for the performance of services; and 
the compensation paid to any shareholder of Antinori will be for services 
actually rendered and will be commensurate with amounts paid to third parties 
bargaining at arm's-length for similar services.

                      CERTIFICATE OF THE CARREKER GROUP, INC.
                           (RE TAX-FREE REORGANIZATION)

     The Carreker Group, Inc., a Texas corporation ("CARREKER"), hereby 
represents, in connection with the proposed merger (the "MERGER") of CAG 
Newco, Inc., a Texas corporation and a wholly-owned subsidiary of Carreker, 
into Antinori Software, Inc., a Georgia corporation ("ANTINORI"), and related 
transactions as set forth under that certain Agreement and Plan of Merger 
dated January 29, 1997 among Carreker, Antinori and CAG Newco, Inc. (the 
"AGREEMENT"), with Antinori surviving the Merger and becoming a wholly-owned 
subsidiary of Carreker, that the following statements are true as of the date 
of this certificate is executed and that the statements will be true as of 
the effective date of the Merger unless the undersigned provides a written 
statement to the contrary prior to the effective date of the Merger:

     A.    CAG Newco, Inc. will be merged with and into Antinori in 
accordance with the relevant merger provisions of Georgia and Texas 
corporation law, and the shareholders of Antinori will receive solely 
Carreker Class A Voting Common Stock, no par value (the "CARREKER COMMON 
STOCK") (except for cash received in lieu of fractional shares), in 
consideration therefor.


                                     Page 1
<PAGE>

     B.    Carreker's and CAG Newco, Inc.'s principal reasons for 
participating in the Merger are bona fide business reasons.

     C.    Carreker does not own, directly or indirectly, nor has it owned 
during the past five years, directly or indirectly, any capital stock of 
Antinori.

     D.    Carreker has not disposed of any assets or declared a special 
dividend as part of the Merger.

     E.    Following the Merger, Carreker will cause Antinori to continue 
Antinori's historic business or Carreker will use a significant portion of 
Antinori's business assets in a business.

     F.    Carreker has no present plan or intention to sell or otherwise 
dispose of, or to cause Antinori to sell or otherwise dispose of, any of the 
assets acquired in the Merger (except for dispositions made in the ordinary 
course of business) or transfers described in Section 368(a)(2)(C) of the 
Internal Revenue Code of 1986, as amended (the "CODE").

     G.    Except for the possible reacquisition of shares pursuant to the 
provisions of an escrow agreement, Carreker has no present plan or intention 
to redeem or otherwise reacquire any of its stock to be issued in the Merger.

     H.    Carreker presently intends to continue to be a duly organized 
corporation, validly existing, licensed and in good standing under the laws 
of the State of Texas prior to and following the effective date of the Merger.

     I.    Carreker will pay its own expenses, if any, incurred in connection 
with the Merger.
      
     J.    Carreker is not an investment company as defined in Section 
368(a)(2)(F) of the Code.

     K.    No shareholder of Antinori is acting as an agent for Carreker in 
connection with the Merger or approval thereof.
      
     L.    The payment of cash by Carreker in lieu of issuing fractional 
shares of Carreker Common Stock is solely for the purpose of avoiding the 
expense and inconvenience to Carreker of issuing fractional shares and does 
not represent separately bargained for consideration.  The Carreker 
fractional share interests to which each Antinori shareholder may be entitled 
in the Merger will be aggregated so that no Antinori shareholder will receive 
cash in an amount which would equal or exceed, in the aggregate, the value of 
one whole share of Carreker Common Stock.

     M.    Except with respect to payments in cash in lieu of fractional 
shares of Carreker voting Common Stock, one hundred percent (100%) of the 
Antinori Common Stock outstanding 

                                     Page 2
<PAGE>

immediately prior to the Merger will be exchanged solely for Carreker Common 
Stock.  Thus, except as set forth in the preceding sentence, Carreker 
intends that no consideration be paid or received (directly or indirectly, 
actually or constructively) for Antinori Common Stock other than Carreker 
Common Stock.
      
     N.    The total fair market value of all consideration other than 
Carreker Common Stock received by Antinori shareholders in exchange for their 
Antinori Common Stock in the Merger (including, without limitation, cash paid 
in lieu of fractional shares) will be less than ten percent (10%) of the 
aggregate fair market value of Antinori Common Stock outstanding immediately 
prior to the Merger.  In addition, the total cash consideration that will be 
paid in the Merger to Antinori shareholders in lieu of fractional shares of 
Carreker Common Stock will not exceed one percent (1%) of the total 
consideration that will be issued in the Merger to the Antinori shareholders 
in exchange for their shares of Antinori Common Stock.
      
     O.    Carreker will pay separately its own expenses in connection with 
the Merger as contemplated by the Agreement; provided, however, that to the 
extent any expenses relating to the Merger (or the "plan of reorganization" 
within the meaning of Treas. Reg. Section 1.368-1(c) with respect to the 
Merger) are funded directly or indirectly by a party other than the incurring 
party, such expenses will be within the guidelines established in Rev. Rul. 
73-54. 1973-1 C.B. 187.

     P.    No intercorporate indebtedness exists between Carreker and 
Antinori that was issued, acquired, or will be settled at a discount, and 
neither Carreker nor CAG Newco, Inc. will assume any liabilities of any 
Antinori shareholder in connection with the Merger.

     Q.    The terms of the Agreement and all other agreements entered into 
pursuant thereto are the product of arm's-length negotiations.

     R.    None of the compensation payments that might be received by any 
shareholder of Antinori will be separate consideration for, or allocable to, 
any of their shares of Antinori Common Stock; none of the shares of Carreker 
Common Stock to be received by any shareholder of Antinori will be separate 
consideration for, or allocable to, any employment agreement, consulting 
agreement or any covenants not to compete; and the compensation which might 
be paid to any shareholder of Antinori will be for the services actually 
rendered and will be commensurate with amounts paid to third parties 
bargaining at arm's-length for similar services.

                             ANTINORI AFFILIATE AGREEMENT

     This Antinori Affiliate Agreement (this "AGREEMENT") is being delivered
concurrently with the execution and delivery of that certain Agreement and Plan
of Merger dated as of January 29, 1997 (the "MERGER AGREEMENT") among The
Carreker Group, Inc., a Texas corporation ("CARREKER"), Antinori Software, Inc.,
a Georgia corporation ("ANTINORI"), and CAG Newco, Inc., a Texas corporation and
a wholly-owned subsidiary of Carreker.  The Merger Agreement provides for the
merger ("MERGER") of CAG Newco, Inc. with and into Antinori in a transaction in
which each share of Antinori Common Stock, par value $.01 per share ("ANTINORI
COMMON STOCK"), will be converted into Carreker Class A Voting Common Stock, no
par value ("CARREKER COMMON STOCK"), as described in the Merger Agreement. 
Unless otherwise defined herein, capitalized terms used in this Agreement have
the meanings given to them in the Merger Agreement.

     The undersigned understands that, because the Merger will be accounted for
as a "pooling-of-interests," shares of Carreker Common Stock which the
undersigned may acquire hereafter may only be disposed of in conformity with the
limitations described herein.

     The undersigned has been informed that the treatment of the Merger as a
pooling-of-interests for financial accounting purposes may depend upon the
accuracy of certain of the representations and warranties and the compliance
with certain of the agreements set forth in this Agreement.  The undersigned
further understands that the representations, warranties and agreements set
forth herein will be relied upon by Carreker, Carreker's shareholders, Antinori,
Antinori's shareholders and Carreker's and Antinori's respective counsel and
accounting firms, for accounting purposes, for federal income tax purposes, for
securities law compliance purposes and for other purposes material to the Merger
Agreement and the consummation of the Merger.

     G.    The undersigned represents, warrants and agrees as follows:

           1.    The undersigned has full power to execute this Agreement and
to make the representations, warranties and agreements herein and to perform the
undersigned's obligations hereunder.

           2.    The undersigned is the beneficial owner of no shares of
Antinori Common Stock.  Except as may be indicated on the last page of this
Agreement, the undersigned does not 


                               Page 1

<PAGE>

beneficially own any shares of Antinori Common Stock, or any options, 
warrants or other rights to acquire shares of Antinori Common Stock or other 
equity securities of Antinori (the "ANTINORI SECURITIES").  At the date of 
this Agreement, the Antinori Securities are, and at all times until the 
"EXPIRATION DATE" (as defined below), the Antinori Securities will be, free 
and clear of any liens, claims, options, charges or other encumbrances, 
except for the rights and obligations created under the Escrow Agreement and 
except as may be indicated on the last page of this Agreement.  As used 
herein, the term "Termination Date" means the earliest to occur of (i) the 
distribution to shareholders of record of Carreker of the first financial 
statements of Carreker that include at least 30 days combined operating 
results of Carreker and Antinori, or (ii) such time as the Merger Agreement 
may be terminated in accordance with its terms.

           3.    The undersigned has no present intention or plan to sell,
exchange or otherwise dispose of Carreker Common Stock to be received by the
undersigned.

           4.    The undersigned is an officer of Antinori and has been
actively involved in the development and marketing of Antinori's products.  The
undersigned is a knowledgeable and sophisticated investor, capable by virtue of
his educational, business and financial background to assess the risks and
merits of investments in Carreker Common Stock.  The undersigned has had the
opportunity to ask questions of and receive full answers from Carreker as to all
matters deemed pertinent by the undersigned to his decision to enter into this
Agreement and to consent to the Merger and the Merger Agreement, and he has
obtained all documents from Carreker that he has requested with respect to such
matters.  The undersigned has not obtained from Carreker or relied upon any
information or documents that are inconsistent with the representations and
covenants made by Carreker in the Merger Agreement.  The undersigned will hold
options to purchase shares of Carreker Common Stock (such options and shares
being the "RESTRICTED SECURITIES") for the undersigned's own account, for
investment and not with a view to resale or other disposition.

     H.    The undersigned agrees as follows:

           1.    At any time prior to the Expiration Date, without the prior
written consent of Carreker, the undersigned will not sell, transfer, encumber
or dispose of, or offer to sell, transfer, encumber or dispose of, (i) any of
the Antinori Securities or (ii) any shares of Antinori Common Stock that the
undersigned purchases or otherwise acquires after the execution of this
Agreement and prior to the Expiration Date (the "NEW ANTINORI SECURITIES").  All
New Antinori Securities will be subject to the terms of this Agreement to the
same extent and in the same manner as they were Antinori Securities.

           2.    Until the Expiration Date, the undersigned will vote any New
Antinori Securities in any vote of the share of Antinori Common Stock, with
respect to the matters referred to in (i) or (ii) immediately below and in every
written consent as a Antinori shareholder solicited with respect to any of the
matters referred to in (i) or (ii) immediately below, as follows: (i) in favor
of approval of the Merger Agreement and the Merger and (ii) against approval of
any proposal that might be in opposition to or in competition with consummation
of the Merger.  The undersigned will not, directly or indirectly, solicit,
facilitate or encourage any offer from any person or entity 


                               Page 2

<PAGE>

concerning the possible disposition of all or any portion of Antinori's 
business, assets or capital stock by merger, sale or other means in 
contravention of the Merger Agreement.

           3.    The undersigned will not, and will not permit any entity under
the undersigned's control to, (i) solicit support in opposition to or in
competition with the consummation of the Merger or otherwise encourage or assist
any person or entity in taking or planning any action that would compete with,
restrain or otherwise serve to interfere with or inhibit the timely consummation
of the Merger in accordance with the terms of the Merger Agreement; or (ii)
initiate a Antinori shareholder vote or action by consent of any Antinori
shareholder in opposition to or in competition with the consummation of the
Merger.

           4.    The undersigned hereby (i) grants any consent or waivers that
are reasonably required, under the terms of any agreement to which the
undersigned and Antinori (or the undersigned, Antinori and another or others)
are parties, for the consummation of the Merger; and (ii) subject to his Letter
Agreement dated October 24, 1996 and Amendment to Letter Agreement dated
January 31, 1997, waives, effective as of the Effective Time, any liquidation,
redemption, anti-dilution, registration rights, information rights, rights of
first refusal, co-sale or other similar rights under terms of the Articles of
Incorporation of Antinori or any agreement with Antinori or its security holders
in effect immediately prior to the Effective Time with respect to the Antinori
Securities.

           5.    The undersigned will execute and deliver any additional
documents reasonably necessary or desirable, in the opinion of Antinori or
Carreker, to carry out the intent of this Agreement.

     I.    The undersigned understands that (a) in addition to the restrictions
imposed under this Agreement, the Restricted Securities have not been registered
under the Securities Act of 1933, as amended (the "SECURITIES ACT"), or
registered or qualified under applicable state securities laws, in reliance upon
the exemptions from the registration or qualification requirements of the
Securities Act of 1933 and such state securities laws, and (b) as a result, the
Restricted Securities may not be offered, resold or otherwise transferred
without registration under the Securities Act and registration and qualification
under applicable state securities laws unless the offer, resale or other
transfer is exempt from the registration or qualification requirements of the
Securities Act and such state securities laws.  The undersigned acknowledges
that, unless registered under the Securities Act, the Restricted Securities may
not be publicly resold except in compliance with Rule 144 or another exemption
from such registration, and that Rule 144 is not presently and for the
foreseeable future will not be available to permit the Restricted Securities to
be resold.

     J.    The undersigned understands that there will be placed on the
certificates evidencing the Restricted Securities that are shares, among other
legends, legends stating in substance:

     "THE SECURITIES REPRESENTED HEREBY MAY BE OFFERED, SOLD OR HYPOTHECATED
ONLY IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT BETWEEN THE REGISTERED HOLDER
THEREOF AND 


                               Page 3

STATE SECURITIES LAWS OR (B) EXEMPTIONS FROM THE REGISTRATION REQUIREMENTS OF
SUCH ACT AND LAWS.  THE COMPANY MAY REQUIRE AN OPINION OF LEGAL COUNSEL, IN FORM
AND SUBSTANCE SATISFACTORY TO THE COMPANY, TO THE EFFECT THAT SUCH EXEMPTIONS
ARE AVAILABLE."

     After release of the distribution described in Section 2(i), certificates
evidencing the Restricted Securities that are shares delivered at or after the
Effective Time may, at the undersigned's election, be surrendered for
cancellation and reissuance without the first of the above legends.  Carreker
agrees that the second legend above will be removed promptly if the provisions
of this Agreement, the Securities Act and applicable state law are otherwise
complied with.

     K.    The undersigned hereby agrees to, and agrees to be bound by, the
indemnification obligations provided for in Section 10.2 of the Merger Agreement
as if the undersigned were a party to the Merger Agreement.

     L.    If any provision of this Agreement (or of the Merger Agreement or
the Escrow Agreement), or the application thereof, is for any reason held to any
extent to be invalid or unenforceable, then the remainder of this Agreement (or
of such of the Merger Agreement or the Escrow Agreement) and application of such
provision to other persons or circumstances will be interpreted so as reasonably
to effect the intent of the parties.  The parties further agree to replace such
unenforceable provision of this Agreement with a valid and enforceable

other purposes of the invalid or unenforceable provisions.

     M.    This Agreement will be binding upon and inure to the benefit of the
parties and their respective successors and permitted assigns, but, except as
otherwise specifically provided herein, neither this Agreement nor any of the
rights, interests or obligations of the parties hereto may be assigned by any of
the parties without prior written consent of the others.

     N.    This Agreement may not be modified, amended, altered or supplemented
except upon the execution and delivery of a written agreement executed by the
parties hereto.

     O.    The undersigned acknowledges that Carreker and Antinori will each be
irreparably harmed and that there will be no adequate remedy at law for a
violation of any of the covenants or agreements of the undersigned set forth
herein.  Therefore, it is agreed that, in addition to any other remedies which
may be available to Carreker and Antinori upon any such violation, Carreker and
Antinori will have the right to enforce such covenants and agreements by
specific performance,

injunctive relief or by any other means available at law or in equity.

     P.    The laws of the State of Texas (without regard to its choice of law
principles that might apply the law of another jurisdiction) will govern the
validity of this Agreement, the construction of its terms, and the
interpretation and enforcement of the rights and duties of the parties.

     Q.    This Agreement contains the entire understanding of the parties with
respect to the subject matter hereof, and supersedes all prior negotiations and
understandings between the parties with respect to such subject matter.

     R.    The failure of any party to enforce any of the provisions of this
Agreement will not be construed to be a waiver of the right of such party
thereafter to enforce such provisions.  The waiver by any party of the right to
enforce any of the provisions of this Agreement on any occasion will not be

     This Antinori Affiliate Agreement (this "AGREEMENT") is being delivered

     The undersigned understands that, because the Merger will be accounted 
for as a "pooling-of-interests" and because the shares of Carreker Common 
Stock to be received by the undersigned in the Merger will not be registered 
under the Securities Act of 1933, as amended (the "SECURITIES ACT"), such 
shares and any shares of Carreker Common Stock which the undersigned may 
acquire hereafter may only be disposed of in conformity with the limitations

     The undersigned has been informed that the treatment of the Merger as a 
pooling-of-interests for financial accounting purposes may depend upon the 
accuracy of certain of the representations and warranties and the compliance 
with certain of the agreements set forth in this Agreement.  The undersigned 
further understands that the representations, warranties and agreements set 
forth herein will be relied upon by Carreker, Carreker's shareholders,

be indicated on the last page of this Agreement, the undersigned does not 
beneficially own any shares of Antinori Common Stock, or any options,

consideration in the Merger other than Carreker Common Stock (including, 
without limitation, cash received pursuant to any exercise of dissenters' 
rights) and/or (ii) with respect to which a sale occurs during the pre-Merger 
period shall be considered shares of outstanding Antinori Common Stock

           5.    The undersigned will execute and deliver any additional 
documents reasonably necessary or desirable, in the opinion of Antinori or 
Carreker, to carry out the intent of this Agreement.

     V.    The undersigned understands that (a) in addition to the 
restrictions imposed under this Agreement, the Restricted Securities have not 
been registered under the Securities Act or registered or qualified under 
applicable state securities laws, in reliance upon the exemptions from the 
registration or qualification requirements of the Securities Act of 1933 and 
such state securities laws, and (b) as a result, the Restricted Securities 
may not be offered, resold or otherwise transferred without registration 
under the Securities Act and registration and qualification under applicable 
state securities laws unless the offer, resale or other transfer is exempt 
from the registration or 

ANTINORI AFFILIATE AGREEMENT - Page 6
<PAGE>

qualification requirements of the Securities Act and such state securities 
laws.  The undersigned acknowledges that, unless registered under the 
Securities Act, the Restricted Securities may not be publicly resold except 
in compliance with Rule 144 or another exemption from such registration, and 
that Rule 144 is not presently and for the foreseeable future will not be 
available to permit the Restricted Securities to be resold.

     W.    The undersigned understands that there will be placed on the 
certificates evidencing the Restricted Securities, among other legends, 
legends stating in substance:

     "THE SECURITIES REPRESENTED HEREBY MAY BE OFFERED, SOLD OR HYPOTHECATED 
ONLY IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT BETWEEN THE REGISTERED 
HOLDER THEREOF AND CARREKER-ANTINORI GROUP, INC. (THE "COMPANY").  A COPY OF 
SUCH AGREEMENT IS ON FILE AT THE PRINCIPAL OFFICE OF THE COMPANY.

     THE SECURITIES REPRESENTED HEREBY MAY BE OFFERED, SOLD OR OTHERWISE 
TRANSFERRED, PLEDGED OR HYPOTHECATED ONLY IN ACCORDANCE WITH (A) AN EFFECTIVE 
REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND UNDER 
APPLICABLE STATE SECURITIES LAWS OR (B) EXEMPTIONS FROM THE REGISTRATION 
REQUIREMENTS OF SUCH ACT AND LAWS.  THE COMPANY MAY REQUIRE AN OPINION OF 
LEGAL COUNSEL, IN FORM AND SUBSTANCE SATISFACTORY TO THE COMPANY, TO THE 
EFFECT THAT SUCH EXEMPTIONS ARE AVAILABLE."

     After release of the distribution described in Section 2(i), 
certificates evidencing the Restricted Securities delivered at or after the 
Effective Time may, at the undersigned's election, be surrendered for 
cancellation and reissuance without the first of the above legends.  Carreker 
agrees that the second legend above will be removed promptly if the 
provisions of this Agreement, the Securities Act and applicable state law are 
otherwise complied with.

     X.    The undersigned hereby agrees to, and agrees to be bound by, the 
indemnification obligations provided for in Section 10.2 of the Merger 
Agreement as if the undersigned were a party to the Merger Agreement.

     Y.    If any provision of this Agreement (or of the Merger Agreement or 
the Escrow Agreement), or the application thereof, is for any reason held to 
any extent to be invalid or unenforceable, 

ANTINORI AFFILIATE AGREEMENT - Page 7
<PAGE>

then the remainder of this Agreement (or of such of the Merger Agreement or 
the Escrow Agreement) and application of such provision to other persons or 
circumstances will be interpreted so as reasonably to effect the intent of 
the parties.  The parties further agree to replace such unenforceable 
provision of this Agreement with a valid and enforceable provisions that will 
achieve, to the extent possible, the economic, business and other purposes of 
the invalid or unenforceable provisions.

     Z.    This Agreement will be binding upon and inure to the benefit of 
the parties and their respective successors and permitted assigns, but, 
except as otherwise specifically provided herein, neither this Agreement nor 
any of the rights, interests or obligations of the parties hereto may be 
assigned by any of the parties without prior written consent of the others.

     AA.   This Agreement may not be modified, amended, altered or 
supplemented except upon the execution and delivery of a written agreement 
executed by the parties hereto.

     BB.   The undersigned acknowledges that Carreker and Antinori will each 
be irreparably harmed and that there will be no adequate remedy at law for a 
violation of any of the covenants or agreements of the undersigned set forth 
herein.  Therefore, it is agreed that, in addition to any other remedies 
which may be available to Carreker and Antinori upon any such violation, 
Carreker and Antinori will have the right to enforce such covenants and 
agreements by specific performance, injunctive relief or by any other means 
available at law or in equity.

     CC.   The laws of the State of Texas (without regard to its choice of 
law principles that might apply the law of another jurisdiction) will govern 
the validity of this Agreement, the construction of its terms, and the 
interpretation and enforcement of the rights and duties of the parties.

     DD.   This Agreement contains the entire understanding of the parties 
with respect to the subject matter hereof, and supersedes all prior 
negotiations and understandings between the parties with respect to such 
subject matter.

     L.   The failure of any party to enforce any of the provisions of this 
Agreement will not be construed to be a waiver of the right of such party 
thereafter to enforce such provisions.  The waiver by any party of the right 
to enforce any of the provisions of this Agreement on any occasion will not 
be construed to be a waiver of the right of such party to enforce such 
provisions on any other occasion.

                          CARREKER AFFILIATE AGREEMENT

     This Carreker Affiliate Agreement (this "AGREEMENT") is being delivered 
in connection with the execution and delivery of that certain Agreement and 
Plan of Merger dated as of January 29, 1997 (the "MERGER AGREEMENT"), among 
The Carreker Group, Inc., a Texas corporation ("CARREKER"), Antinori 
Software, Inc., a Georgia corporation ("ANTINORI"), and CAG Newco, Inc., a 
Texas corporation and a wholly-owned subsidiary of Carreker. The Merger 
Agreement provides for the merger (the "MERGER") of CAG Newco, Inc. with and 
into Antinori in a transaction in which each share of Antinori Common Stock, 
par value $.01 per share, will be converted into shares of Carreker Class A 
Voting Common Stock, no par value ("CARREKER CLASS A STOCK").

     The undersigned understands that, since the Merger will be accounted for 
as a "pooling-of-interests," the shares of Carreker Class A Stock which the 
undersigned holds or may hereafter acquire may be disposed of only in 
conformity with the limitations described herein. The undersigned has been 
informed that the treatment of the Merger as a pooling-of-interests for 
financial accounting purposes is dependent upon the accuracy of certain of 
the representations and warranties and the compliance with certain of the 
agreements set forth herein. The undersigned further understands that the 
representations, warranties and agreements set forth herein will be relied 
upon by Carreker and its counsel and accounting firm.

     1.    The undersigned represents, warrants and agrees as follows:

           (a)   The undersigned has full power to execute this Agreement and 
to make the representations, warranties and agreements herein and to perform 
the undersigned's obligations hereunder.

                                     Page 1
<PAGE>

           (b)   The undersigned is the beneficial owner of (and has sole or 
shared voting or investment power with respect to) all the shares of Carreker 
Class A Stock and options to purchase shares of Carreker Class B Non-Voting 
Common Stock as indicated on the last page hereof (collectively, and together 
with any such shares acquired after the date hereof, the "CARREKER 
SECURITIES"). Except for the Carreker Securities, the undersigned does not 
beneficially own any shares of Carreker Class A Stock or any other equity 
securities of Carreker or any options, warrants or other rights to acquire 
shares of Carreker Class A Stock or other equity securities of Carreker.

           (c)   The undersigned will not sell, transfer, encumber, or 
otherwise dispose of any of the Carreker Securities or offer or agree to 
sell, transfer, encumber, or otherwise dispose of, or in any other way reduce 
the undersigned's risk of ownership or investments in, any of such Carreker 
Securities from and after the date hereof until Carreker shall have 
distributed to its shareholders of record its first financial statements that 
include at least 30 days of combined operating results of Carreker and 
Antinori; provided, however, that nothing in this paragraph will be deemed to 
prohibit charitable contributions of such securities without consideration to 
transferees who agree to all of the restrictions in this Agreement and 
provided further that, if the Merger Agreement should be terminated in 
accordance with its terms prior to the effectiveness of the Merger, the 
undersigned will have no obligations under this Agreement from and after the 
date of such termination.

     2.    This Agreement will be binding upon and enforceable against 
administrators, executors, representatives, heirs, legatees and devisees of 
the undersigned and any pledgee holding Carreker Securities as collateral. If 
the Merger Agreement is terminated in accordance with its terms prior to the 
effectiveness of the Merger, then this Agreement will automatically terminate.

Attention:  Ronald R. Antinori, Chairman of the Board

     Re:   Agreement and Plan of Merger dated as of January 29, 1997 among The
           Carreker Group, Inc., CAG Newco, Inc. and Antinori Software, Inc.

Ladies and Gentlemen:

     We have acted as counsel to The Carreker Group, Inc., a Texas 
corporation (the "Company"), and J.D. Carreker ("Carreker") in connection 
with the preparation of that certain Agreement and Plan of Merger (the 
"Agreement") between the Company, CAG Newco, Inc., a Texas corporation 
("Newco"), and Antinori Software, Inc. ("ASI").  As such, we have 
participated in the closing of the merger of Newco with and into the Company 
and the receipt of shares of the Company by the shareholders of ASI (the 
"Transaction").  This opinion is rendered pursuant to Section 7.4 of the 
Agreement.

     The various documents and agreements executed and delivered pursuant to 
the Agreement and in connection with the consummation of the Transaction are 
sometimes referred to herein as the Transaction Documents.  To the extent not 
otherwise defined herein, defined terms have the meaning ascribed to them in 
the Agreement.

     This opinion is governed by, and is to be interpreted in accordance 
with, the Legal Opinion Accord (the "Accord") of the ABA Section of Business 
Law (1991).  As a consequence, it is subject to the assumptions, 
qualifications (including the General Qualifications), exceptions, 
definitions, limitations on coverage and other limitations, all as more 
particularly described in the Accord.  This opinion should be read in 
conjunction therewith.

     In the capacity described above, we have considered such matters of law 
and of fact, including the examination of originals or copies, certified or 
otherwise identified to our satisfaction, of such records and documents of 
the Company, certificates of officers and representatives of the Company, 
certificates of public officials and such other documents as we have deemed 
appropriate as a basis for the opinions hereinafter set forth.

                                     Page 1
<PAGE>

     The opinions set forth herein are limited to the laws of The State of 
Texas and applicable federal laws as applied therein.

     Based upon the foregoing, it is our opinion that:

     (1)   The Company was duly organized as a corporation, and is existing 
and in good standing under the laws of the State of Texas.

     (2)   The Company has the corporate power to execute and deliver the 
Agreement and the other Transaction Documents, to perform its obligations 
thereunder, to own and use its assets and to conduct its business.

     (3)   The Company has duly authorized the execution and delivery of the 
Agreement and all performance by the Company thereunder.  The Company and 
Carreker have duly executed and delivered the Agreement and the other 
Transaction Documents to which each is a party.

     (4)   The execution and delivery by the Company and Carreker of the 
Transaction Documents to which each is a party do not, and performance by the 
Company and Carreker of their respective obligations under the Agreement and 
the other Transaction Documents will not, result in any:

     (i)   violation of the Company's articles of incorporation or bylaws;

     (ii)  violation of any existing federal or state constitution, law,
           statute, regulation or rule to which the Company or its assets or
           Carreker is subject;

     (iii) breach of or default under any material written agreements;
     
     (iv)  creation or imposition of a contractual lien or security interest
           in, on or against the assets of the Company under any material
           written agreements; or 

     (v)   violation of any judicial or administrative decree, writ, judgment
           or order to which, to our knowledge, the Company or its assets or
           Carreker is subject.

With your permission we have assumed that the term "material written 
agreements" used in clauses (iii) and (iv) above includes only those 
agreements identified in ATTACHMENT 1 to this letter.

     (5)   Other than the filing of the Articles of Merger with the Secretary
of State of The 

                                     Page 3
<PAGE>

State of Texas, no consent, approval, authorization or other action by, or 
filing with, any governmental authority of the United States of America or 
The State of Texas is required for the Company's execution and delivery of 
the Agreement and consummation of the Transaction.

     (6)   The Transaction Documents are enforceable against the Company and 
Carreker, respectively, as applicable.

     (7)   The Company's authorized shares consist of 12,000,000 shares of 
Class A Voting Common Stock, 500,000 shares of Class B Non-Voting Common 
Stock, and 5,000,000 shares of Preferred Stock, each no par value, of which 
961,071 shares of Class A Voting Common Stock and 3,167 shares of Class B 
Non-Voting Common Stock are issued and outstanding as of the Closing Date and 
are held of record as set forth in SCHEDULE 3.3 to the Agreement.  Except as 
disclosed on the Schedules to the Agreement, as of the Closing Date, to our 
knowledge there are no other options, warrants, or other agreements pursuant 
to which any other person could acquire shares or other any interest in the 
shares of the Company.

     (8)   The shares of Class A Voting Common Stock of the Company to be 
issued in the Merger have been duly authorized and upon their issuance will 
be validly issued, fully paid and nonassessable.

     Based upon the limitations and qualifications set forth above, we also 
confirm to you that:

     (1)   To our knowledge, no litigation or other proceeding against the 
Company or any of its property is pending or overtly threatened by a written 
communication to the Company.

     (2)   The Company is incorporated under the laws of The State of Texas, 
but is not qualified to conduct business in any state other than The State of 
Texas.

     In addition to other limitations noted in the Accord, the enforceability 
of the Transaction Documents may be limited by:

     (i)    the possible unenforceability of waivers or advance consents that
            have the effect of waiving statutes of limitation, marshalling of
            assets or similar requirements, or, as to the jurisdiction of
            courts, the venue of actions, the right to jury trial, or in
            certain cases, notices;

                                     Page 4
<PAGE>

     (ii)   the possible unenforceability of provisions that waivers or
            consents by a party may not be given effect unless in writing or in
            compliance with particular requirements or that a person's course
            of dealing, course of performance, or the like or failure or delay
            in taking actions may not constitute a waiver of related rights or
            provisions or that one or more waivers may not, under certain
            circumstances, constitute a waiver of other matters of the same
            kind;

     (iii)  the effect of course of dealing, course of performance, or the like
            that would modify the terms of an agreement or the respective
            rights or obligations of the parties under an agreement;

     (iv)   the possible unenforceability of provisions that enumerated
            remedies are non-exclusive or that a party has the right to pursue
            multiple remedies without regard to other remedies elected or that
            all remedies are cumulative;

     (v)    the possible unenforceability of provisions that determination by a
            party or a party's designee are conclusive;

     (vi)   the possible unenforceability of provisions that the provisions of
            an agreement are severable in all circumstances;

     (vii)  the effect of laws requiring mitigation of damages;

     (viii) the possible unenforceability of provisions permitting the
            exercise, under certain circumstances, of rights without notice or
            without providing opportunity to cure failures to perform;

     (ix)   the effect of agreements as to rights of setoff otherwise than in
            accordance with applicable law; and

     (x)    the possible unenforceability of any covenant not to compete set
            forth in the Transaction Documents if its limitations as to time,
            geographical area and scope of activity to be restrained are not
            reasonable or impose a greater restraint than is necessary to
            protect the goodwill or other business interest of the Company.

           Newco, Inc. and Antinori Software, Inc. dated as of January 30, 1997

Ladies and Gentlemen:

     We have acted as counsel to Antinori Software, Inc., a Georgia 
corporation, and Ronald R. Antinori, its controlling shareholder, in 
connection with the preparation of the Agreement and Plan of Merger (the 
"Agreement") between The Carreker Group, Inc. ("Carreker"), CAG Newco, Inc. 
("Newco") and Antinori Software, Inc. ("ASI") and have participated in the 
closing of the merger of Newco with and into ASI and the receipt of shares of 
Carreker by the existing shareholders (the "Shareholders") of ASI ("the 
Transaction").  This opinion letter is rendered pursuant to Section 8.4 of 
the Agreement.

     The various documents and agreements executed and delivered pursuant to 
the Agreement and in connection with the consummation of the Transaction are 
sometimes referred to herein as the Transaction Documents.  To the extent not 
otherwise defined herein, defined terms have the meaning ascribed to them in

qualifications (including the General Qualifications), exceptions, 
definitions, limitations on coverage and other limitations, all as more 
particularly described in the Accord.  This Opinion Letter should be read in

     In the capacity described above, we have considered such matters of law and
of fact, including the examination of originals or copies, certified or
otherwise identified to our satisfaction, of such records and documents of ASI,
certificates of officers and representatives of ASI, certificates of public
officials and such other documents as we have deemed appropriate as a basis for
the opinions hereinafter set forth.

     The opinions set forth herein are limited to the laws of the State of
Georgia and applicable federal laws as applied therein.  To the extent that any
document or agreement is governed by the laws of the State of Texas, we have
assumed at your request and with your permission, that the laws of the State of
Georgia are identical to, the laws of the State of Texas.

     Based upon the foregoing, it is our opinion that:

                                     Page 1
<PAGE>

     (1)   ASI was duly organized as a corporation, and is existing and in 
good standing, under the laws of the State of Georgia.

     (2)   ASI has the corporate power to execute and deliver the Agreement 
and other Transaction Documents, to perform its obligations thereunder, to 
own and use its assets and to conduct its business.

     (3)   ASI has duly authorized the execution and delivery of the 
Agreement and all performance by ASI thereunder and ASI and the Shareholders 
have duly executed and delivered the Agreement and the other Transaction 
Documents to which each is a party.

     (4)   The execution and delivery by ASI and the Shareholders of the 
Transaction Documents do not, and performance by ASI and the Shareholders of 
their respective obligations under the Agreement and the Transaction 
Documents will not result in any:

           (i)   violation of ASI's articles of incorporation or bylaws;

           (ii)  violation of any existing federal or state constitution, 
statute, regulation, rule, order, or law to which ASI or its assets or the 
Shareholders are subject;

           (iii) breach of or default under any material written agreements;

           (iv)  creation or imposition of a contractual lien or security 
interest in, on or against the assets of ASI under any material written 
agreement; or

           (v)   violation of any judicial or administrative decree, writ 
judgment or order to which, to our knowledge, ASI or its assets or the 
Shareholders are subject.

With your permission we have assumed that the term "material written 
agreements" used in clauses (iii) and (iv) above includes only those 
agreements identified in the Schedules delivered pursuant to the Agreement.

     (5)   Other than the filing of the Certificate of Merger with the 
Secretary of State of Georgia, no consent, approval, authorization or other 
action by, or filing with, any governmental authority of the United States or 
the State of Georgia is required for ASI's execution and delivery of the 
Agreement and consummation of the Transaction.

     (6)   The Transaction Documents are enforceable against ASI and the 
Shareholders respectively as applicable.

                                     Page 2

     (7)   ASI's authorized shares consist of 10,000,000 shares of Common 
Stock one cent ($.01) par value per share of which 1,010,101 shares were 
issued and outstanding and are owned of record by the persons identified in 
Schedule 2.3 to the Agreement.  The outstanding shares have been duly 
authorized and validly issued and are fully paid and nonassessable.  Except 
for a certain agreement between Lawrence D. Duckworth and Ronald R. Antinori 
dated October 24, 1995 with respect to options on certain shares of ASI held 
by Ronald R. Antinori, as amended to apply to certain of the shares of 
Carreker issued to Ronald R. Antinori in the merger, as of the closing, to 
our knowledge there are no other options, warrants, or other agreements 
pursuant to which any other person could acquire shares or other any interest 
in the shares of ASI.

     (8)   Immediately prior to the consummation of the Transaction, the 
Shareholders were the sole registered owners of the shares of ASI.  Following 
the consummation of the Transaction, Carreker is the sole registered owner of 
all shares of ASI.

     Based upon the limitations and qualifications set forth above, we also   
   confirm to you that:

     (1)     To our knowledge, no litigation or other proceeding against ASI 
or any of its property is pending or overtly threatened by a written 
communication to ASI.

     (2)    ASI is incorporated under the laws of the State of Georgia, but 
is not qualified to conduct business in any state other than the State of 
Georgia.

     In addition to other limitations noted in the Accord, the enforceability 
of the Transaction Documents may be limited by:

     (i)    the possible unenforceability of waivers or advance consents that 
have the effect of waiving statutes of limitation, marshalling of assets or 
similar requirements, or, as to the jurisdiction of courts, the venue of 
actions, the right to jury trial, or in certain cases, notices;

     (ii)   the possible unenforceability of provisions that waivers or 
consents by a party may not be given effect unless in writing or in 
compliance with particular requirements or that a person's course of dealing, 
course of performance, or the like or failure or delay in taking actions may 
not constitute a waiver of related rights or provisions or that one or more 
waivers may not, under certain circumstances, constitute a waiver of other 
matters of the same kind;

     (iii)  the effect of course of dealing, course of performance, or the 
like that would modify the terms of an agreement or the respective rights or 
obligations of the parties under an agreement;

     (iv)   the possible unenforceability of provisions that enumerated 
remedies are non-exclusive or that a party has the right to pursue multiple 
remedies without regard to other 

                                     Page 3
<PAGE>

remedies elected or that all remedies are cumulative;

     (v)    the effect of O.C.G.A. Section  13-1-11 on provisions relating to 
attorneys' fees;

     (vi)   the possible unenforceability of provisions that determination by 
a party or a party's designee are conclusive;

     (vii)  the possible unenforceability of provisions permitting 
modifications of an agreement only in writing;

     (viii) the possible unenforceability of provisions that the provisions 
of an agreement are severable in all circumstances;

     (ix)   the effect of laws requiring mitigation of damages;

     (x)    the possible unenforceability of provisions permitting the 
exercise, under certain circumstances, of rights without notice or without 
providing opportunity to cure failures to perform;

     (xi)   the effect of agreements as to rights of setoff otherwise than in 
accordance with applicable law; and

     (xii)  the possible unenforceability of any covenant not to compete set 
forth in the Transaction Documents if its limitations as to time, 
geographical area and scope of activity to be restrained are not reasonable 
or impose a greater restraint than is necessary to protect the goodwill or 
other business interest of Carreker.

     This opinion letter is provided to you for your exclusive use solely in 
connection with the Transaction, and may not be relied upon by any other 
person or for any other purpose without our prior written consent.

                                           Very truly yours,

                       II.  RESTRICTIONS ON TRANSFER OF SHARES

or any right or interest therein, except as provided in this Article II.

            (b)   Anything in this Agreement to the contrary notwithstanding,
no Transfer of any Shares otherwise permitted or required by this Agreement
shall be made unless such Transfer is in compliance with federal and state
securities laws, including, without limitation, the Securities Act.  In

the proposed Transfer of the Shares may be effected without registration under
the Securities Act and applicable state securities laws, or (ii) a "no-action"
letter from the staff of the Commission to the effect that the proposed Transfer
of such Shares without registration under the Securities Act would not result in
a recommendation by the staff that action be taken in respect thereof.

            (c)   Anything in this Agreement to the contrary notwithstanding,
unless otherwise agreed to in writing by the Company and the Shareholders, no
Transfer of Shares otherwise permitted or required by this Agreement shall be
effective unless and until the transferee shall execute and deliver to the
Company an agreement in a form satisfactory to the Company in which such
transferee agrees in writing to be bound by this Agreement and to observe and
comply with this Agreement and with all obligations and restrictions imposed on
the Shareholders hereby.


                                    Page 3

<PAGE>

Each person to whom a Transfer of Shares is permitted by this Agreement who 
receives a Transfer of Shares during the period when this Agreement is in 
effect, and who so agrees in writing to be bound by the provisions hereof, 
shall thereafter become a "Shareholder" for all purposes of this Agreement.

            (d)   Transfers of the Shares may only be made in strict compliance
with all applicable terms of this Agreement.  Any purported Transfer of the
Shares that does not comply with all applicable provisions of this Agreement
shall be null and void and of no force or effect, and the Company shall not
recognize nor will be bound by any such purported Transfer and shall not effect
any such purported Transfer on its stock transfer books.

            (e)   Any offer to Transfer Shares by a Shareholder shall be deemed
to include an offer to sell all Shares or interest therein (including community
property interest) owned by or for the benefit of the spouse of the Shareholder,
whether or not stated in the offer.  By executing this Agreement, a
Shareholder's spouse hereby agrees to be bound by all terms and provisions of
this Agreement.

            (f)   Any Transfer of Shares by a Shareholder to his or her
immediate family (i.e., the spouse, children, parents or siblings of the
Shareholder), or to a trust for the benefit of the Shareholder or his or her
immediate family, shall not be prohibited under this Agreement, provided each
such transferee receives the Shares subject to the terms and provisions of this
Agreement as a Shareholder as provided in Section 2.1(c) above.

     2.2    RIGHT OF FIRST REFUSAL.

            (a)   If any Shareholder proposes to Transfer any Shares owned by
him to a third party (a "Proposed Transfer"), then such Shareholder (the
"Offering Shareholder") shall first offer such Shares to the Company by sending
a written offer (the "Offer") to the Company, and by sending a copy of the Offer
to each other Shareholder, in each case as provided in Section 6.1.  The Offer
shall set forth (i) the number of Shares subject to the Proposed Transfer (the
"Offered Shares"), (ii) a description of the Proposed Transfer, (iii) the
identity of each prospective purchaser (the "Transferee"), and (iv) any and all
other material terms (the "Terms") of the Proposed Transfer, including without
limitation, the purchase price per Offered Share offered by the Transferee, the
manner in which such purchase price shall be paid and the description of any
non-cash consideration.

            (b)   Within fifteen (15) business days after receipt of the Offer
(the "Offer Date") the Company may elect to purchase all, but not less than all,
of the Offered Shares.  The Company shall exercise its election to purchase the
Offered Shares by giving written notice to the Offering Shareholder specifying a
date for the closing of the purchase, which date shall not be more than forty
(40) days after the Offer Date.


                                    Page 4

<PAGE>

            (c)   The Company, if it elects to accept the Offer, shall purchase
the Offered Shares at the price and upon the Terms set forth in the Offer.  At
the closing of such purchase, the Company shall deliver the consideration for
the Offered Shares and the Offering Shareholder shall deliver to the Company
stock certificates representing the Offered Shares duly endorsed in blank or
accompanied by appropriate stock powers duly executed in blank.

            (d)   If the Offered Shares are not purchased by the Company
pursuant to this Section 2.2, then the Offering Shareholder shall comply with
the provisions of Section 2.3.  If the Offering Shareholder does not consummate
the sale of the Offered Shares to the Transferee within ninety (90) days after
the Offer Date, then the Offered Shares shall again become subject to all of the
restrictions of this Agreement.

            (e)   The right of first refusal established pursuant to this
Section 2.2 shall not apply to a Transfer of Shares by Antinori to Lawrence D.
Duckworth pursuant to Section 2 of that Amendment to Letter Agreement dated as
of even date herewith between them.

     2.3    RIGHT OF PARTICIPATION IN SALES.

            (a)   If the Offered Shares are not purchased by the Company
pursuant to Section 2.2 above, then all Shareholders other than the Offering
Shareholder (each, a "Non-offering Shareholder," and together, the "Non-offering
Shareholders") shall be entitled to participate in the Proposed Transfer in the
manner and to the extent set forth in this Section 2.3.  Each Non-offering
Shareholder who desires to participate in the Proposed Transfer shall give
written notice of such desire to the Offering Shareholder within twenty (20)
business days following the Offer Date.  Each Non-offering Shareholder who gives
such notice shall be entitled to sell in the Proposed Transfer, in accordance
with the Terms, a portion of the Shares then held by the Non-offering
Shareholder as described in subsection (b) below.  The Offering Shareholder
shall assign so much of his or her interest in any instrument or agreement
governing the Proposed Transfer as each electing Non-offering Shareholder shall
be entitled to and shall request hereunder, and each Non-offering Shareholder
shall assume such part of the obligations of the Offering Shareholder under such
instrument or agreement as it shall relate to the sale of securities by the
Offering Shareholder.

            (b)   Each Non-offering Shareholder may sell up to a Pro Rata
portion of the Offered Shares in the Proposed Transfer if the same are not sold
pursuant to Section 2.2.  As to a Non-offering Shareholder, "Pro Rata" means in
the proportion of the number of Shares owned by such Non-offering Shareholder
bears to the aggregate number of Shares owned by all Shareholders as of the
Offer Date; provided, however, that if Carreker is the Offering Shareholder,
then as to a Non-offering Shareholder "Pro Rata" means in the proportion of the
number of Shares owned by such Non-offering Shareholder bears to the aggregate
number of Shares owned as of the Offer Date 


                                    Page 5

<PAGE>

by all Shareholders and David Sias (if David Sias elects to exercise his 
right to sell Shares in the Proposed Transfer pursuant to the provisions of 
that certain Stock Purchase Agreement dated as of November 5, 1993 among the 
Company, David Sias and Carreker).

            (c)   To the extent that a Non-offering Shareholder who is
otherwise entitled to does not elect to sell all of his or her Pro Rata portion
of the Offered Shares in the Proposed Transfer pursuant to this Section 2.3,
then the Offering Shareholder may sell the Offered Shares (less that number of
Shares sold in the Proposed Transfer by Non-offering Shareholders, if any) to
the Transferee in accordance with the Terms for a period of ninety (90) days
following the Offer Date.  If the Offering Shareholder fails to make any such
sale within ninety (90) days after the Offer Date, then such Offered Shares
shall again become subject to all of the restrictions of this Agreement.

            (d)   The right of participation established by this Section 2.3
shall not apply in respect of the redemption by the Company of Shares held by a
Shareholder out of either of the two escrows established pursuant to the Merger
Agreement.

                              III.  REGISTRATION RIGHTS

     III.1.  DEMAND REGISTRATION.

             (a)    At any time from and after one year after the closing of a
Qualified Public Offering, Shareholders holding not less than fifty percent
(50%), on a fully-diluted basis, of the capital stock of the Company entitled to
vote in the election of directors (the "Selling Shareholders") may by written
notice (a "Demand Notice") to the Company require the registration under the
Securities Act of all or part of the Shares held by the Selling Shareholders (a
"Demand Registration"); provided, however, that the amount of Shares to be
offered for sale under a Demand Registration (the "Registrable Shares") shall
have either a fair market value of $10 million or more.  The Company shall not
be obligated to effect more than two (2) Demand Registrations under this Section
3.1, plus two (2) Demand Registrations as to which the Demand Notice is given by
Selling Shareholders that include Antinori (on behalf of the ASI Shareholders,
as provided in Section 3.1(h)).  No Demand Notice may be given prior to six
months after the effective date of the immediately preceding Demand
Registration.

             (b)    Demand Registrations shall be on such appropriate
registration form of the Commission (i) as shall be selected by the Company and
as shall be reasonably acceptable to the Selling Shareholders and (ii) as shall
permit the Transfer of the Registrable Shares in accordance with the intended
method of Transfer specified by the Selling Shareholders in their Demand Notice.

             (c)    The Company will file a Registration Statement relating to
any Demand 


                                    Page 6

<PAGE>

Registration within sixty (60) days of the date of the applicable Demand 
Notice and will use all reasonable efforts to cause the same to be declared 
effective by the Commission within one hundred twenty (120) days of the date 
of such Demand Notice.  If any Demand Registration is requested to be 
effected as a "shelf" registration, then the Company will keep the 
Registration Statement filed in respect thereof effective for a period of up 
to four (4) months from the date on which the Commission declares such 
Registration Statement effective, or such shorter period that will terminate 
when all Registrable Shares covered by such Registration Statement have been 
sold pursuant to such Registration Statement.

             (d)    A registration requested pursuant to this Section 3.1 will
not count as a Demand Registration (i) unless a Registration Statement with
respect thereto has become effective, (ii) if after such Registration Statement
has become effective, such registration is interfered with by any stop order,
injunction or other order or requirement of the Commission or other governmental
agency or court not due to any fault of the Selling Shareholders, (iii) if,
solely due to the fault of the Company, the conditions to closing specified in
the purchase agreement or underwriting agreement entered into in connection with
such registration are not satisfied, or (iv) if the Registration Statement is
withdrawn because the Selling Shareholders determine, with the Company's prior
written consent, that the price to be received in connection with the offering
of the Registrable Shares is inadequate.  Subject to the provision relating to
the payment of costs and expenses set forth in Section 3.5, the Company agrees
to withdraw any Registration Statement filed pursuant to this Section 3.1 upon
the request of the Selling Shareholders who gave a Demand Notice in respect of
same.

             (e)    If the offering of Registrable Shares pursuant to a Demand
Registration is to be an underwritten offering, then the Selling Shareholders
shall select the managing underwriters in connection with such offering and any
additional investment bankers to be used in connection with the offering,
subject to the approval of the Company, which shall not be unreasonably
withheld.

             (f)    If the managing underwriter or underwriters of an
underwritten offering to which such Demand Registration relates advises the
Selling Shareholders that the total amount of Registrable Shares intended to be
included in such Demand Registration is in the aggregate such as to materially
and adversely affect the success of such offering, then the number of
Registrable Shares to be included in such Demand Registration will, if
necessary, be reduced and there will be included in such underwritten offering
the number of Registrable Shares that, in the opinion of such managing
underwriter or underwriters, can be sold without materially and adversely
affecting the success of such offering, allocated PRO RATA among the Selling
Shareholders on the basis of the amount of Registrable Shares requested to be
included therein by each such Selling Shareholder.

             (g)    The Company will be entitled to postpone the filing of any
Demand Registration for a reasonable period of time not in excess of 120
calendar days, if the Company 


                                    Page 7

<PAGE>

determines, in the good faith exercise of the business judgment of its board 
of directors, that such registration and offering could materially interfere 
with BONA FIDE financing plans of the Company or would require disclosure of 
information the premature disclosure of which could adversely affect the 
Company.  If the Company postpones the filing of a Registration Statement, 
then it will promptly notify the Selling Shareholders in writing when the 
events or circumstances permitting such postponement have ended.

             (h)    For purposes of this Section 3.1, the ASI Shareholders
hereby irrevocably consent to the appointment of Antinori, as representative of
the ASI Shareholders, and as attorney-in-fact for and on behalf of each ASI
Shareholder, for purposes of giving a Demand Notice.

     III.2.  INCIDENTAL REGISTRATION.

             (a)    If the Company proposes to file a Registration Statement
under the Securities Act on Form S-1, S-2 or S-3 (or any successor form)
relating to any offering of Shares to be offered for its own account for cash
(other than a Demand Registration or a Registration Statement filed in
connection with an exchange offer or offering of securities solely to the
Company's existing shareholders), then the Company shall (i) provide prompt
written notice of the proposed offering to the Shareholders, include in such
written notice a description of the intended method of distribution, and
(ii) use all reasonable efforts to register pursuant to such Registration
Statement (an "Incidental Registration") such number of Shares ("Registrable
Shares") as shall be specified in a written request by a Shareholder (each, a
"Selling Shareholder") made within ten (10) days after such written notice from
the Company, subject to subsection (b) below.

             (b)    Notwithstanding any other provision of this Section 4.2, if
a registration pursuant to this Section 4.2 involves a firm commitment,
underwritten offering of the securities so being registered, and if the managing
underwriter of such offering informs the Company and the Selling Shareholders by
letter of its belief that marketing factors require a limitation of the number
of shares to be underwritten, then the Company may limit the number of
Registrable Shares to be included in the registration and underwriting, with
first priority being given to Shares proposed to be issued by the Company, and
second priority being given to Shares proposed to be sold by a Selling
Shareholder, and, if more than one Selling Shareholder exists, then by the
Selling Shareholders on a pro rata basis (determined by the inclusion of any
Shares held by David Sias, in the manner provided in Section 2.3(b), if J.D.
Carreker is a Selling Shareholder and if David Sias elects to exercise his right
to sell Shares in the Proposed Transfer pursuant to the provisions of that
certain Stock Purchase Agreement dated as of November 5, 1993 among the Company,
David Sias and Carreker).

             (c)    Notwithstanding the foregoing, if, at any time after giving
written notice to the Selling Shareholders of its proposal to file a
Registration Statement pursuant to subsection (a)

above and prior to the effective date of such Registration Statement, the 
Company shall determine for any reason not to register the Shares proposed to 
be covered thereby, then the Company may, at its election, give written 
notice of such determination to the Selling Shareholders and thereupon shall 
be relieved of its obligation to register any Registrable Shares in 
connection with such registration (but not from its obligation to pay certain 
expenses in connection therewith as provided in Section 3.5), without 
prejudice, however, to the rights the Shareholders otherwise may have to 
request that such registration be effected under Section 3.1.  No 
registration effected under this Section shall relieve the Company of its 
obligation to effect any Demand Registration under Section 3.1

     III.3.  COOPERATION.  Each Selling Shareholder hereby agrees to cooperate
and provide all information necessary to assure that any Registration Statement
required hereunder shall be filed promptly and be declared effective by the
Commission as soon as reasonably practicable after the filing thereof.

     III.4.  RESTRICTIONS ON PUBLIC SALE BY SHAREHOLDERS.  Each Shareholder
agrees not to effect any public sale or distribution of the Registrable Shares,
including a sale pursuant to Rule 144 under the Securities Act, during the
twenty (20) days prior to, and during the one hundred eighty (180) day period
beginning on, the effective date of a Registration Statement (except as part of
such registration) if and to the extent requested by the Company in the case of
a non-underwritten offering or if and to the extent requested by the managing
underwriter in the case of an underwritten offering.

     III.5.  REGISTRATION EXPENSES.  In connection with each Demand
Registration and each Incidental Registration, the Company shall, except as
otherwise specifically provided, pay all expenses incurred in connection with
such registration, including without limitation (a) filing fees with the
Commission; (b) fees and expenses of compliance with the securities or "blue
sky" laws in connection with "blue sky" registrations or qualifications of the
Registrable Shares, (c) preparation and printing expenses, (d) fees and expenses
of counsel and independent certified public accountants for the Company;
(e) fees and expenses of one counsel for the Selling Shareholders, which counsel
shall be designated by the Selling Shareholders in the written notice sent to
the Company requesting the Demand Registration or Incidental Registration and
shall be subject to the approval by the Company, and (g) fees and expenses of
any additional experts retained by the Company in connection with such
registration.  The Selling Shareholders shall pay any underwriting discounts or
commissions or brokers' fees or commissions attributable to the sale of the
Registrable Shares.  Notwithstanding the foregoing, if the Selling Shareholders
request the Company to withdraw a Registration Statement for a Demand
Registration that has become effective, then the Selling Shareholders agree to
reimburse the Company an amount equal to fifty percent (50%) of the total fees
and expenses incurred by the Company up to the time of the withdrawal.

     III.6.  INDEMNIFICATION BY THE COMPANY.  The Company agrees to, and hereby
does, indemnify and hold harmless each Selling Shareholder from and against any
and all losses, claims, damages and liabilities caused by any untrue statement
or alleged untrue statement of a material fact contained in any Registration
Statement or prospectus relating to the Registrable Shares or any amendment or
supplement thereto, or caused by any omission or alleged omission to state
therein a material fact required to be stated therein or when necessary to make
the statements therein not misleading, and will reimburse each Selling
Shareholder for any legal or other out-of-pocket expenses reasonably incurred in
connection with investigating or defending any such losses, claims, damages or
liabilities (or any proceeding in respect thereof), except insofar as such
losses, claims, damages or liabilities are caused by such untrue statement or
omission or alleged untrue statement or omission based upon and in conformity
with information furnished to the Company by or on behalf of the Selling
Shareholder expressly for use therein.

     III.7.  INDEMNIFICATION BY THE SELLING SHAREHOLDERS.  Each Selling
Shareholder severally, but not jointly, agrees to and hereby does, indemnify and
hold harmless the Company, its officers and directors, and each person, if any,
who controls the Company within the meaning of either Section 15 of the
Securities Act or Section 20 of the Securities Exchange Act of 1934, as amended,
to the same extent as the foregoing indemnity from the Company to the Selling
Shareholders, but only with reference to information furnished by or on behalf
of such Selling Shareholders, expressly for use in any Registration Statement or
prospectus relating to the Registrable Shares, or any amendment or supplement
thereto.

     III.8.  ASSIGNMENT.  Subject to the provisions of this Agreement, the
right to cause the Company to register Registrable Shares under this Article may
be assigned to any assignee of Registrable Shares or transferred to any
successor of the Shareholders.

     III.9.  CROW FAMILY HOLDINGS, L.P.  Notwithstanding anything herein to the
contrary, Article III of this Agreement shall be subject to and construed so as
to give effect to and not create any conflict with, Section 9 (captioned "Right
of Inclusion") of that certain Stock Purchase Agreement dated as of January 10,
1997 by and between Crow Family Partnership, L.P. and The Carreker Group, Inc.

     III.10. CESSATION OF STATUS AS REGISTRABLE SHARES.  Notwithstanding any 
provision herein to the contrary, Shares shall cease to be Registrable Shares 
(a) if they are effectively registered under the Securities Act and disposed 
of in accordance with the Registration Statement wherein they are registered, 
(b) if they are saleable by the Shareholder thereof pursuant to Rule 144(k), 
or (c) they are distributed to the public by the Shareholder thereof pursuant 
to Rule 144.

                                    IV. GOVERNANCE

     IV.1.   BOARD REPRESENTATION.  The board of directors of the Company will
be comprised of such number of directors as is determined by the board of
directors or otherwise as provided in the constituent documents of the Company. 
At each annual shareholders meeting of the Company, and at each special
shareholders meeting of the Company called for the purpose of electing directors
of the Company, and at any time at which shareholders of the Company shall have
the right to, or shall, vote for directors of the Company, then, and in each
event, the Shareholders hereby agree to vote all Shares owned by them for the
nomination and election of a board of directors that will include the following:

     (i)     Antinori and one other individual designated by him;

     (ii)    Carreker and three other individuals designated by him; and

     (iii)   one individual designated by Science Applications International
Corporation ("SAIC") (or such greater number of individuals as SAIC shall be
entitled to designate pursuant to that certain Shareholders Agreement dated as
of October 10, 1996 among the Company, Carreker and SAIC).

Notwithstanding any other provision of this Agreement, however, no Shareholder
will be required to cause the election of any designee, or to support the
continued service of any director, if the board of directors of the Company
determines in good faith, based as to legal matters on the advice of counsel,
that the election or continued service of such designee would be inconsistent
with the fiduciary duty owed by the board of directors of the Company to the
shareholders of the Company, provided, however, that the foregoing shall not
detract from the right of an individual who designated such designee to nominate
another designee for such position.

     In addition, if a person entitled to designate another person for election
as a director of the Company desires to cause his designee to be removed from
the board of directors of the Company, then the Shareholders hereby agree to, if
necessary, but subject to all applicable requirements of law, use their best
efforts to take or cause to be taken all such action as may be required to
remove such designee from the board of directors of the Company.

     IV.2.   CASH SALES OF STOCK TO AFFILIATES.  The Shareholders hereby agree
to use their best efforts to cause the Company to amend its Bylaws to require an
affirmative vote of at least the Requisite Number of directors to approve an
issuance for cash of new shares of capital stock of the Company to an Affiliate;
provided, however, that such amendment shall not require such affirmative vote
to approve the issuance of capital stock upon the exercise of a stock option or
options or to approve the grant of a stock option or options.  The Requisite
Number as used herein shall mean the total number of directors of the Company
then constituting its board of directors, 


                                   Page 11

less two.  This Section 4.2 shall not apply in respect of sale of capital 
stock to Science Applications International Corporation resulting from its 
exercise of its contractual preemptive right as set forth in Section 2.1 
(captioned "SAIC Right of First Refusal on Future Securities") of that 
certain Shareholder Agreement among the Company, Carreker and Science 
Applications International Corporation, as the same may be amended from time 
to time.

                            V.  TERMINATION OF PROVISIONS

     V.1.    TERMINATION.  Except for the provisions of Article II and Article
IV, which shall terminate immediately prior to the first consummation of a
Qualified Public Offering (and to which Article II shall not apply in respect of
a Qualified Public Offering), this Agreement shall remain in effect until
terminated by the agreement of the Company, Antinori (acting as representative
and attorney-in-fact for the ASI Shareholders) and Carreker.  This Agreement
shall also terminate upon the closing of the sale of all or substantially all of
the assets of the Company, the consolidation or merger of the Company in which
the Company is not the surviving corporation or the liquidation of the Company
in accordance with the Texas Business Corporation Act.

                                  VI.  MISCELLANEOUS

      VI.2.  AMENDMENTS.  This Agreement, including any attachments, contains
the entire agreement and supersedes and replaces all prior agreement by and
among the Company and the Shareholders regarding its subject matter.  This
Agreement may not be changed or modified in whole or in part except by a writing
signed by the party against whom enforcement of the change or modification is
sought.  Notwithstanding the prior sentence, Sections 3.1 and Section 4.1 may be


                                   Page 13

<PAGE>

amended by Antinori and Carreker only, without the consent or agreement of any
other Shareholder.

      VI.3.  SUCCESSORS AND ASSIGNS.  Except as provided in Section 3.8, this
Agreement will not be assignable by any party without the prior written consent
of all other parties.

      VI.4.  GOVERNING LAW.  The laws of the State of Texas (without regard to
its choice of law principles that might apply the law of another jurisdiction)
will govern the validity of this Agreement, the construction of its terms, and
the interpretation and enforcement of the rights and duties of the parties.

      VI.5.  NO WAIVER.  The failure of any party to enforce any of the
provisions hereof will not be construed to be a waiver of the right of such
party thereafter to enforce such provisions.  The waiver by any party of the
right to enforce any of the provisions hereof on any occasion will not be
construed to be a waiver of the right of such party to enforce such provisions
on any other occasion.

      VI.6.  SEVERABILITY.  The parties hereto recognize that the limitations
contained in this Agreement are reasonably and properly required for the
adequate protection of their interests.  If for any reason a court of competent
jurisdiction or an arbitrator in a binding arbitration proceeding finds any
provision of this Agreement, or the application thereof, to be unenforceable,
then the remaining provisions of this Agreement will be interpreted so as best
to reasonably effect the intent of the parties.  The parties further agree that
the court or arbitrator shall replace any such invalid or unenforceable
provisions with valid and enforceable provisions designed to achieve, to the
extent possible, the business purposes and intent of such unenforceable
provisions.

      VI.7.  COUNTERPARTS.  This Agreement may be executed in counterparts,
each of which will be an original as regards any party whose signature appears
thereon and all of which together will constitute one and the same instrument. 
This Agreement will become binding when one or more counterparts hereof,
individually or taken together, bear the signatures of both parties reflected
hereon as signatories.

      VI.8.  DISPUTE RESOLUTION.

             (a)    ARBITRATION OF DISPUTES.  Any dispute under this Agreement
shall be resolved by arbitration in Dallas, Texas and, except as herein
specifically stated, in accordance with the commercial arbitration rules of the
American Arbitration Association ("AAA RULES") then in effect.  However, in all
events, these arbitration provisions shall govern over any conflicting rules
that may now or hereafter be contained in the AAA Rules.  Any judgment upon the
award rendered by the arbitrator may be entered in any court having jurisdiction
over the subject matter thereof.  The arbitrator shall have the authority to
grant any equitable and legal remedies that would be available in any judicial
proceeding instituted to resolve such dispute.

             (b)    COMPENSATION OF ARBITRATOR.  Any such arbitration will be
conducted before a single arbitrator who will be compensated for his or her
services at a rate to be determined by the parties or by the American
Arbitration Association, but based upon reasonable hourly or daily consulting
rates for the arbitrator if the parties are not able to agree upon his or her
rate of compensation.

             (c)    SELECTION OF ARBITRATOR.  The American Arbitration
Association will have the authority to select an arbitrator from a list of
arbitrators who are lawyers familiar with Texas corporation law and Texas
contract law; provided, however, that such lawyers cannot work for a firm then
performing services for either party, that each party will have the opportunity
to make such reasonable objection to any of the arbitrators listed as such party
may wish and that the American Arbitration Association will select the
arbitrator from the list of arbitrators as to whom neither party makes any such
objection.  If the foregoing procedure is not followed, then each party will
choose one person from the list of arbitrators provided by the American
Arbitration Association (provided that such person does not have a conflict of
interest), and the two persons so selected will select from the list provided by
the American Arbitration Association the person who will act as the arbitrator.

             (d)    PAYMENT OF COSTS.  The parties to the arbitration will each
pay an equal share of the initial compensation to be paid to the arbitrator in
any such arbitration and of the costs of transcripts and other normal and
regular expenses of the arbitration proceedings; provided, however, that the
prevailing party in any arbitration will be entitled to an award of attorneys'
fees and costs, and all costs of arbitration, including those provided for
above, will be paid by the non-prevailing party or parties, and the arbitrator
will be authorized to make such determinations.

             (e)    BURDEN OF PROOF.  For any dispute submitted to arbitration,
the burden of proof will be as it would be if the claim were litigated in a
Texas judicial proceeding.


                                   Page 15

<PAGE>

             (f)    AWARD.  Upon the conclusion of any arbitration proceedings
hereunder, the arbitrator will render findings of fact and conclusions of law
and a written opinion setting forth the basis and reasons for any decision
reached and will deliver such documents to each party to this Agreement along
with a signed copy of the award.

             (g)    TERMS OF ARBITRATION.  The arbitrator chosen in accordance
with these provisions will not have the power to alter, amend or otherwise
affect the terms of these arbitration provisions or the provisions of this
Agreement.

             (h)    NATURE OF REMEDY.  Except as specifically otherwise provided
in this Agreement, arbitration will be the sole and exclusive remedy of the
parties for any dispute arising out of this Agreement.

             (i)    EQUITABLE REMEDY.  Notwithstanding the provisions of this
Section 6.8 and the arbitration provided for herein, actions initiated or
maintained by the parties for injunctive or similar equitable relief may not be
subject to arbitration and may be brought by the parties in any court that has
jurisdiction, and should the party bringing any such action prevail, all costs
and expenses (including legal fees) shall be borne by the party against whom
such action was brought.

      VI.9.  LEGEND.  A legend referring to the restrictions imposed by this
Agreement and otherwise complying with Article 2.30 of the Texas Business
Corporation Act may be placed upon any certificate issued to evidence Shares.

      NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, the parties hereto hereby agree as
follows:

           1.    GRANT OF OPTION.  Subject to the terms and conditions
hereinafter set forth, the Company, with the approval and at the direction of
the Committee, hereby grants to the Employee, as of the date hereof, an option
(the "Option") to purchase 15,720 shares of Stock (the "Option Shares") at a
price of $19.07 per share (the "Exercise Price"), representing the Fair Market
Value per Share (or, if Employee is the owner of stock possessing more than 10
percent of the total combined voting power of all classes of stock of the
Company, or its parent or subsidiary corporation, if any, 110% of the Fair
Market Value per 


                                    Page 1

<PAGE>

Share) as of the Date of Grant as determined by the Committee in accordance 
with the Plan.  The Option is intended by the parties hereto to be, and shall 
be treated as, an incentive stock option (as such term is defined under 
Section 422 of the Internal Revenue Code of 1986, as amended (the "Code")).

      2.   VESTING.  The Option shall vest and become exercisable during the
two-year period following the date hereof (herein the "Vesting Period") as
follows:

           (a)   The Option shall be immediately vested and exercisable with
respect to one-third (1/3) of the Option Shares on the date hereof;

           (b)   The Option shall vest and shall be exercisable with respect to
an additional one-third (1/3) of the Option Shares on the first anniversary date
of this Agreement, provided Employee is employed by the Company or one of its
subsidiaries as of such date and has been continuously employed during the term
of this Agreement, and further provided that the Option has not otherwise
terminated in accordance with the terms of Section 4 hereof; and
      
           (c)   The Option shall vest and shall be exercisable with respect to
the remaining one-third (1/3) of the Option Shares on the second anniversary
date of this Agreement, provided Employee is employed by the Company or one of
its subsidiaries as of such date and has been continuously employed by the
Company or one of its subsidiaries during the term of this Agreement, and
further provided that the Option has not otherwise terminated in accordance with
the terms of Section 4 hereof.

      3.   EXERCISE OF OPTION. The Option, to the extent vested, may be
exercised as follows:

           (a)   The Employee may exercise the Option with respect to all or
any part of the Option Shares then vested by giving the Secretary of the Company
written notice (the "Notice") of intent to exercise.  The Notice shall specify
the number of Option Shares to be exercised (which shall be an amount no less
than 50 shares or the number of shares as to which the Option is then
exercisable, if less than 50) and the date of the proposed exercise thereof (the
"Exercise Date"), which date shall be at least ten (10) but no more than thirty
(30) calendar days after the giving of such notice unless an earlier time shall
have been mutually agreed upon.

           (b)   Full payment (in U.S. dollars) by the Employee of 


                                    Page 2

<PAGE>

the Exercise Price shall be made on or before the Exercise Date in cash or 
certified check.

           (c)   On or before the Exercise Date, Employee and his spouse, if
any, shall execute and deliver to the Company an agreement restricting the
transferability of the Option Shares substantially in the form of Exhibit A
attached hereto (the "Right of First Refusal Agreement");

           (d)   On the Exercise Date or as soon thereafter as practicable
thereafter, the Company shall cause to be delivered to the Employee a
certificate or certificates for the Option Shares then being purchased upon full
payment for such Option Shares.  Such certificate or certificates shall bear a
restrictive legend in the form set forth in the Transfer Restriction Agreement. 
The obligation of the Company to deliver the Option Shares shall, however, be
subject to the condition that if at any time the Committee shall determine in
its discretion that the listing, registration or qualification of the Option or
the Option Shares upon any securities exchange or under any state or federal
law, or the consent or approval of any governmental regulatory body, is
necessary or desirable as a condition of, or in connection with, the Option or
the issuance or purchase of Stock thereunder, the Option may not be exercised in
whole or in part unless such listing, registration, qualification, consent or
approval shall have been effected or obtained free of any conditions not
acceptable to the Committee.

           (e)   If Employee fails to pay the Exercise Price by the Exercise
Date for any of the Option Shares specified in the Notice or fails to deliver
the Transfer Restriction Agreement, the Employee's right to purchase such Option
Shares may be terminated by the Company upon written notice to Employee.  

      4.   TERMINATION OF OPTION.  The Option, and all rights hereunder with
respect thereto, to the extent such rights shall not have been exercised, shall
terminate and become null and void on the earliest to occur of the following
dates as follows:

           (a)   the tenth (10th) anniversary date of the date hereof, or, if
Employee is the owner of stock possessing more than 10 percent of the total
combined voting power of all classes of stock of the Company, or its parent or
subsidiary corporation, if any, the fifth (5th) anniversary date of the date
hereof (the "Expiration Date");

           (b)   in the event Employee's employment with the Company or any
subsidiary is terminated, other than by reason of death or Disability (as
defined below) or termination for Cause (as defined below), then (i) this Option
shall continue to vest 


                                    Page 3

<PAGE>

and shall be exercisable as though Employee's employment with the Company 
continued for a period of two (2) years following the date of termination of 
employment, and (ii) this Option shall terminate and shall no longer be 
exercisable after the passage of two (2) years from the date of termination 
of employment, but in no event later than the Expiration Date (and further 
provided that in the event this Option is exercised following the expiration 
of three (3) months from the date of termination of employment, the portion 
of this Option so exercised will be treated as a non-qualified option as 
required by the Code).  In such a case, the Employee's only rights hereunder 
shall be those which have been properly exercised prior to the termination or 
earlier expiration of this Option;

           (c)   in the event Employee's employment with the Company or any
subsidiary is terminated for Cause (as defined below), then no further
installments of this Option shall vest or otherwise become exercisable, if such
termination occurs during the Vesting Period, and this Option shall terminate
and shall no longer be exercisable effective on the date of such termination. 
For purposes hereof, the term "Cause" shall mean conduct involving one or more
of the following as determined by the Committee in its reasonable discretion:
(i) the substantial and continuing failure of the Employee, after notice
thereof, to render services to the Company or any subsidiary in accordance with
the terms or requirements of the Employee's employment with the Company or any
subsidiary; (ii) disloyalty, gross negligence, willful misconduct, dishonesty or
breach of fiduciary duty to the Company or any subsidiary; (iii) the commission
of an act of embezzlement or fraud; (iv) deliberate disregard of the rules or
policies of the Company which results in direct or indirect loss, damage or
injury to the Company or any subsidiary; (v) the unauthorized disclosure of any
trade secret or confidential information of the Company or any subsidiary; or
(vi) the commission of an act which constitutes unfair competition with the
Company or any subsidiary or which induces any customer or supplier to break a
contract with the Company or any subsidiary;

           (d)   in the event Employee dies while employed with the Company or
any subsidiary, this Option may be exercised, to the extent vested on the date
of his death, by the Employee's executor, estate, personal representative or
beneficiary, as the case may be, and to whom this Option is transferred by
operation of law, at any time within one (1) year after the date of death, but
not later than the Expiration Date.  Following the expiration of such one-year
period, this Option shall terminate;

           (e)   in the event Employee's employment with the Company or any
subsidiary is terminated by reason of his Disability (which shall mean
"permanent and total disability" as 


                                    Page 4

<PAGE>

defined in Section 22(e)(3) of the Code, or any successor statute), this 
Option may be exercised, to the extent vested on the date of such Disability, 
at any time within one (1) year after the date of such Disability, but not 
later than Expiration Date.  Following the expiration of such one-year 
period, this Option shall terminate;

           (f)   the closing date of any Capital Transaction (as defined in
Section 6 hereof); or

           (g)   the date the Company gives written notice to Employee of
Employee's failure to pay the Exercise Price as provided in Section 3(e) hereof.

      5.   ADJUSTMENT OF AND CHANGES IN STOCK OF THE COMPANY.    In the event of
a reorganization, recapitalization, change of shares, stock split, spin-off,
stock dividend, reclassification, subdivision or combination of shares, merger,
consolidation, rights offering, or any other change in the corporate structure
or shares of capital stock of the Company, the Committee shall make such
adjustment as it deems appropriate in the number and kind of shares of Stock
subject to the Option or in the Exercise Price; PROVIDED HOWEVER, that no such
adjustment shall give the Employee any additional benefits under the Option.

      6.   CAPITAL TRANSACTIONS.  In the event that following the date of this
Agreement during the term hereof and prior to the termination of the Option in
accordance with Section 4 hereof, there shall occur (a) a merger or
consolidation of the Company with or into another corporation in which the
Company shall not be the surviving corporation (for purposes of this Section 6,
the Company shall not be deemed the surviving corporation in any such
transaction if, as the result thereof, it becomes a wholly-owned subsidiary of
another corporation), (b) a dissolution of the Company, (c) a transfer of all or
substantially all of the assets or shares of stock of the Company in one
transaction or a series of related transactions to one or more other persons or
entities, or (d) a distribution of the Company's equity securities to the public
pursuant to a registration statement filed under the Securities Act of 1933, as
amended, or any successor statute (any such transaction being referred to herein
as a "Capital Transaction"), then the Company shall provide Employee with thirty
(30) days advance written notice of such transaction and Employee, without the
necessity of any further action by the Committee, shall be entitled to purchase,
prior to the effective date of such Capital Transaction and in addition to the
number of Option Shares which Employee shall be entitled to purchase as
determined under Section 2 hereof, the number of remaining Option Shares which
have not then become vested.  The unexercised portion of the Option shall be
deemed cancelled and terminated as of the effective date 


                                    Page 5

<PAGE>

of such transaction.

      7.   RIGHTS OF SHAREHOLDER.  Neither the Employee nor any heir, personal
representative or other person shall be, or shall have any of the rights and
privileges of, a shareholder of the Company with respect to any shares of Stock
purchasable or issuable upon the exercise of the Option, in whole or in part,
prior to the date of exercise of the Option.

      8.   TRANSFERABILITY OF OPTION.  During Employee's lifetime, the Option
hereunder shall be exercisable only by the Employee or any guardian or legal
representative of the Employee, and the Option shall not be transferable except,
in case of the death of the Employee, by will or the laws of descent and
distribution, nor shall the Option be subject to attachment, execution or other
similar process.  In the event of (a) any attempt by Employee to alienate,
assign, pledge, hypothecate or otherwise dispose of the Option, except as
provided for herein, or (b) the levy of any attachment, execution or similar
process upon the rights or interest hereby conferred, the Company may terminate
the Option by notice to the Employee and it shall thereupon become null and
void.

      9.   EMPLOYMENT NOT AFFECTED.  Neither the granting of the Option nor its
exercise shall be construed as granting to the Employee any right with respect
to continuance of employment.  Except as may otherwise be limited by a written
agreement between the Company or one of its subsidiaries, as the case may be,
and the Employee, the right of the Company (or one of its subsidiaries) to
terminate the Employee's employment at any time is specifically reserved.

      10.  AMENDMENT OF OPTION.  The Option and this Agreement may be amended
by the Board or the Committee at any time without the consent of Employee (i) if
the Board or the Committee determines, in its sole discretion, that the
amendment is necessary or advisable in the light of any addition to or change in
the Code or in the regulations issued thereunder, or any federal or state
securities law or other law or regulation, which change occurs after the date
hereof and by its terms applies to the Option; or (ii) in order to make the
adjustments set forth in Section 5 hereof.  Other than the matters set forth in
the preceding sentence, the consent of Employee shall be required in order to
amend any other provision of this Agreement.  Notwithstanding the foregoing, the
Committee may, in its sole discretion, accelerate the exercisability of the
Option at any time.

      11.  NOTICES. Any notice to the Company provided for in this Agreement
shall be addressed to it in care of its Secretary at the Company's executive
offices. Any notice to the Employee 


                                    Page 6

<PAGE>

shall be addressed to Employee at the current address shown on the payroll 
records of the Company.  Any notice shall be deemed to be duly given if and 
when properly addressed and posted by registered or certified mail, postage 
prepaid.

      12.  INCORPORATION OF PLAN BY REFERENCE. The Option is granted pursuant
to the terms of the Plan, the terms of which are incorporated herein by
reference, and the Option shall in all respects be interpreted in accordance
with the Plan.  The Committee shall interpret and construe the Plan and this
Agreement, and its interpretations and determinations shall be conclusive and
binding on the parties hereto and any other person claiming an interest
hereunder, with respect to any issue arising hereunder or thereunder.  In the
event any of the terms and conditions set forth in this Agreement are in

accordance with the law of the State of Texas.

      14.  CAPITALIZED TERMS.  Unless otherwise defined herein, each
capitalized term appearing in this Agreement shall have the same meaning as the
corresponding term in the Plan.    

      15.  BINDING EFFECT.  This Agreement shall be binding upon the parties
hereto, together with their respective executors, administrators, successors,
personal representatives, heirs and assigns.

      16.  ENTIRE AGREEMENT.  This Agreement embodies the entire agreement and
understanding between the parties hereto with respect to the subject matter

terminated effective as of the date hereof).

      17.  COUNTERPARTS.  This Agreement may be executed in counterparts,
each of which shall be deemed an original, but all of which together shall
constitute one instrument.

IN RELIANCE ON PARAGRAPH (13) OF CODE SECTION 10-5-9 OF THE GEORGIA SECURITIES
ACT OF 1973 AND MAY NOT BE SOLD OR TRANSFERRED EXCEPT IN A TRANSACTION WHICH IS

                           INCENTIVE STOCK OPTION AGREEMENT
                          (CLASS B NON-VOTING COMMON STOCK)

      This Agreement ("Agreement") is dated this ________ day of January, 1997
by and among The Carreker Group, Inc., a Texas corporation (the "Company") and
Michael Israel ("Employee").

      WHEREAS, the Board of Directors of the Company (the "Board") has adopted,
and the shareholders of the Company have approved, The Carreker Group, Inc.
Amended and Restated 1994 Long Term Incentive Plan (the "Plan");

      WHEREAS, the Plan provides for the granting of incentive stock options by
the Compensation Committee of the Board or any successor committee thereto (the
"Committee") to officers and key employees of the Company or any subsidiary of
the Company and its subsidiaries to purchase shares of the Company's Class B
Non-Voting Common Stock, no par value (the "Stock"), in accordance with the
terms and provisions thereof; and

      WHEREAS, the Committee considers Employee to be a person who is eligible
for a grant of incentive stock options under the Plan, and has determined that
it would be in the best interest of the Company to grant the incentive stock
option described herein.

      NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, the parties hereto hereby agree as
follows:

           1.    GRANT OF OPTION.  Subject to the terms and conditions
hereinafter set forth, the Company, with the approval and at the direction of
the Committee, hereby grants to the Employee, as of the date hereof, an option
(the "Option") to purchase 15,720 shares of Stock (the "Option Shares") at a
price of $19.07 per share (the "Exercise Price"), representing the Fair Market
Value per Share (or, if Employee is the owner of stock possessing more than 10
percent of the total combined voting power of all classes of stock of the
Company, or its parent or subsidiary corporation, if any, 110% of the Fair
Market Value per Share) as of the Date of Grant as determined by the Committee
in accordance with the Plan.  The Option is intended by the parties hereto to
be, and shall be treated as, an incentive stock option (as such term is defined
under Section 422 of the Internal Revenue Code of 1986, as amended (the

      2.   VESTING.  The Option shall vest and become exercisable during the
two-year period following the date hereof (herein the "Vesting Period") as
follows:

           (a)   The Option shall be immediately vested and exercisable with
respect to one-third (1/3) of the Option Shares on the date hereof;

           (b)   The Option shall vest and shall be exercisable with respect to
an additional one-third (1/3) of the Option Shares on the first anniversary date
of this Agreement, provided Employee is employed by the Company or one of its
subsidiaries as of such date and has been continuously employed during the term
of this Agreement, and further provided that the Option has not otherwise
terminated in accordance with the terms of Section 4 hereof; and

           (c)   The Option shall vest and shall be exercisable with respect to
the remaining one-third (1/3) of the Option Shares on the second anniversary
date of this Agreement, provided Employee is employed by the Company or one of
its subsidiaries as of such date and has been continuously employed by the
Company or one of its subsidiaries during the term of this Agreement, and
further provided that the Option has not otherwise terminated in accordance with
the terms of Section 4 hereof.

      3.   EXERCISE OF OPTION. The Option, to the extent vested, may be
exercised as follows:

           (a)   The Employee may exercise the Option with respect to all or
any part of the Option Shares then vested by giving the Secretary of the Company
written notice (the "Notice") of intent to exercise.  The Notice shall specify
the number of Option Shares to be exercised (which shall be an amount no less
than 50 shares or the number of shares as to which the Option is then
exercisable, if less than 50) and the date of the proposed exercise thereof (the
"Exercise Date"), which date shall be at least ten (10) but no more than thirty
(30) calendar days after the giving of such notice unless an earlier time shall
have been mutually agreed upon.

           (b)   Full payment (in U.S. dollars) by the Employee of the Exercise
Price shall be made on or before the Exercise Date in cash or certified check.

           (c)   On or before the Exercise Date, Employee and his spouse, if

                                       2

<PAGE>

agreement restricting the transferability of the Option Shares substantially 
in the form of Exhibit A attached hereto (the "Right of First Refusal 
Agreement");

           (d)   On the Exercise Date or as soon thereafter as practicable
thereafter, the Company shall cause to be delivered to the Employee a
certificate or certificates for the Option Shares then being purchased upon full
payment for such Option Shares.  Such certificate or certificates shall bear a
restrictive legend in the form set forth in the Right of First Refusal
Agreement.  The obligation of the Company to deliver the Option Shares shall,
however, be subject to the condition that if at any time the Committee shall
determine in its discretion that the listing, registration or qualification of
the Option or the Option Shares upon any securities exchange or under any state
or federal law, or the consent or approval of any governmental regulatory body,
is necessary or desirable as a condition of, or in connection with, the Option
or the issuance or purchase of Stock thereunder, the Option may not be exercised
in whole or in part unless such listing, registration, qualification, consent or
approval shall have been effected or obtained free of any conditions not
acceptable to the Committee.

           (e)   If Employee fails to pay the Exercise Price by the Exercise
Date for any of the Option Shares specified in the Notice or fails to deliver
the Right of First Refusal Agreement, the Employee's right to purchase such
Option Shares may be terminated by the Company upon written notice to Employee.

      4.   TERMINATION OF OPTION.  The Option, and all rights hereunder with
respect thereto, to the extent such rights shall not have been exercised, shall
terminate and become null and void on the earliest to occur of the following
dates as follows:

           (a)   the tenth (10th) anniversary date of the date hereof, or, if
Employee is the owner of stock possessing more than 10 percent of the total
combined voting power of all classes of stock of the Company, or its parent or
subsidiary corporation, if any, the fifth (5th) anniversary date of the date
hereof (the "Expiration Date");

           (b)   in the event Employee's employment with the Company or any
subsidiary is terminated, other than by reason of death or Disability (as
defined below) or termination for Cause (as defined below), then (i) this Option
shall continue to vest and shall be exercisable as though Employee's employment
with the Company continued for a period of two (2) years following the date 


                                       3

<PAGE>

of termination of employment, and (ii) this Option shall terminate and shall 
no longer be exercisable after the passage of two (2) years from the date of 
termination of employment, but in no event later than the Expiration Date 
(and further provided that in the event this Option is exercised following 
the expiration of three (3) months from the date of termination of 
employment, the portion of this Option so exercised will be treated as a 
non-qualified option as required by the Code).  In such a case, the 
Employee's only rights hereunder shall be those which have been properly 
exercised prior to the termination or earlier expiration of this Option;

           (c)   in the event Employee's employment with the Company or any
subsidiary is terminated for Cause (as defined below), then no further
installments of this Option shall vest or otherwise become exercisable, if such
termination occurs during the Vesting Period, and this Option shall terminate
and shall no longer be exercisable effective on the date of such termination. 
For purposes hereof, the term "Cause" shall mean conduct involving one or more
of the following as determined by the Committee in its reasonable discretion:
(i) the substantial and continuing failure of the Employee, after notice
thereof, to render services to the Company or any subsidiary in accordance with
the terms or requirements of the Employee's employment with the Company or any
subsidiary; (ii) disloyalty, gross negligence, willful misconduct, dishonesty or
breach of fiduciary duty to the Company or any subsidiary; (iii) the commission
of an act of embezzlement or fraud; (iv) deliberate disregard of the rules or
policies of the Company which results in direct or indirect loss, damage or
injury to the Company or any subsidiary; (v) the unauthorized disclosure of any
trade secret or confidential information of the Company or any subsidiary; or
(vi) the commission of an act which constitutes unfair competition with the
Company or any subsidiary or which induces any customer or supplier to break a
contract with the Company or any subsidiary;

           (d)   in the event Employee dies while employed with the Company or
any subsidiary, this Option may be exercised, to the extent vested on the date
of his death, by the Employee's executor, estate, personal representative or
beneficiary, as the case may be, and to whom this Option is transferred by
operation of law, at any time within one (1) year after the date of death, but
not later than the Expiration Date.  Following the expiration of such one-year
period, this Option shall terminate;

           (e)   in the event Employee's employment with the Company or any
subsidiary is terminated by reason of his 


                                       4

<PAGE>

Disability (which shall mean "permanent and total disability" as defined in 
Section 22(e)(3) of the Code, or any successor statute), this Option may be 
exercised, to the extent vested on the date of such Disability, at any time 
within one (1) year after the date of such Disability, but not later than 
Expiration Date.  Following the expiration of such one-year period, this 
Option shall terminate;

           (f)   the closing date of any Capital Transaction (as defined in
Section 6 hereof); or

           (g)   the date the Company gives written notice to Employee of
Employee's failure to pay the Exercise Price as provided in Section 3(e) hereof.

      5.   ADJUSTMENT OF AND CHANGES IN STOCK OF THE COMPANY.  In the event of
a reorganization, recapitalization, change of shares, stock split, spin-off,
stock dividend, reclassification, subdivision or combination of shares, merger,
consolidation, rights offering, or any other change in the corporate structure
or shares of capital stock of the Company, the Committee shall make such
adjustment as it deems appropriate in the number and kind of shares of Stock
subject to the Option or in the Exercise Price; PROVIDED HOWEVER, that no such
adjustment shall give the Employee any additional benefits under the Option.

      6.   CAPITAL TRANSACTIONS.  In the event that following the date of this
Agreement during the term hereof and prior to the termination of the Option in
accordance with Section 4 hereof, there shall occur (a) a merger or
consolidation of the Company with or into another corporation in which the
Company shall not be the surviving corporation (for purposes of this Section 6,
the Company shall not be deemed the surviving corporation in any such
transaction if, as the result thereof, it becomes a wholly-owned subsidiary of
another corporation), (b) a dissolution of the Company, (c) a transfer of all or
substantially all of the assets or shares of stock of the Company in one
transaction or a series of related transactions to one or more other persons or
entities, or (d) a distribution of the Company's equity securities to the public
pursuant to a registration statement filed under the Securities Act of 1933, as
amended, or any successor statute (any such transaction being referred to herein
as a "Capital Transaction"), then the Company shall provide Employee with thirty
(30) days advance written notice of such transaction and Employee, without the
necessity of any further action by the Committee, shall be entitled to purchase,
prior to the effective date of such Capital Transaction and in addition to the
number of Option Shares 


                                       5

<PAGE>

which Employee shall be entitled to purchase as determined under Section 2 
hereof, the number of remaining Option Shares which have not then become 
vested.  The unexercised portion of the Option shall be deemed cancelled and 
terminated as of the effective date of such transaction.

      7.   RIGHTS OF SHAREHOLDER.  Neither the Employee nor any heir, personal
representative or other person shall be, or shall have any of the rights and
privileges of, a shareholder of the Company with respect to any shares of Stock
purchasable or issuable upon the exercise of the Option, in whole or in part,
prior to the date of exercise of the Option.

      8.   TRANSFERABILITY OF OPTION.  During Employee's lifetime, the Option
hereunder shall be exercisable only by the Employee or any guardian or legal
representative of the Employee, and the Option shall not be transferable except,
in case of the death of the Employee, by will or the laws of descent and
distribution, nor shall the Option be subject to attachment, execution or other
similar process.  In the event of (a) any attempt by Employee to alienate,
assign, pledge, hypothecate or otherwise dispose of the Option, except as
provided for herein, or (b) the levy of any attachment, execution or similar
process upon the rights or interest hereby conferred, the Company may terminate
the Option by notice to the Employee and it shall thereupon become null and
void.

      9.   EMPLOYMENT NOT AFFECTED.  Neither the granting of the Option nor its
exercise shall be construed as granting to the Employee any right with respect
to continuance of employment.  Except as may otherwise be limited by a written
agreement between the Company or one of its subsidiaries, as the case may be,
and the Employee, the right of the Company (or one of its subsidiaries) to
terminate the Employee's employment at any time is specifically reserved.

      10.  AMENDMENT OF OPTION.  The Option and this Agreement may be amended
by the Board or the Committee at any time without the consent of Employee (i) if
the Board or the Committee determines, in its sole discretion, that the
amendment is necessary or advisable in the light of any addition to or change in
the Code or in the regulations issued thereunder, or any federal or state
securities law or other law or regulation, which change occurs after the date
hereof and by its terms applies to the Option; or (ii) in order to make the
adjustments set forth in Section 5 hereof.  Other than the matters set forth in
the preceding sentence, the consent of Employee shall be required in order to


                                       6

amend any other provision of this Agreement.  Notwithstanding the foregoing, the
Committee may, in its sole discretion, accelerate the exercisability of the
Option at any time.

shall be addressed to it in care of its Secretary at the Company's executive
offices. Any notice to the Employee shall be addressed to Employee at the
current address shown on the payroll records of the Company.  Any notice shall
be deemed to be duly given if and when properly addressed and posted by
registered or certified mail, postage prepaid.

      12.  INCORPORATION OF PLAN BY REFERENCE. The Option is granted pursuant
to the terms of the Plan, the terms of which are incorporated herein by
reference, and the Option shall in all respects be interpreted in accordance
with the Plan.  The Committee shall interpret and construe the Plan and this
Agreement, and its interpretations and determinations shall be conclusive and
binding on the parties hereto and any other person claiming an interest
hereunder, with respect to any issue arising hereunder or thereunder.  In the
event any of the terms and conditions set forth in this Agreement are in
conflict or are inconsistent with the terms of the Plan, the terms of the Plan

effect of this instrument shall exclusively be governed by and determined in
accordance with the law of the State of Texas.

understanding between the parties hereto with respect to the subject matter
hereof and supersedes all prior agreements and understandings relating to the

                        INCENTIVE STOCK OPTION AGREEMENT
                       (CLASS B NON-VOTING COMMON STOCK)

      This Agreement ("Agreement") is dated this __________ day of January, 
1997 by and among The Carreker Group, Inc., a Texas corporation (the 
"Company") and Ruth McCullough ("Employee").

      WHEREAS, the Board of Directors of the Company (the "Board") has 
adopted, and the shareholders of the Company have approved, The Carreker 
Group, Inc. Amended and Restated 1994 Long Term Incentive Plan (the "Plan");

      WHEREAS, the Plan provides for the granting of incentive stock options 
by the Compensation Committee of the Board or any successor committee thereto 
(the "Committee") to officers and key employees of the Company or any 
subsidiary of the Company and its subsidiaries to purchase shares of the 
Company's Class B Non-Voting Common Stock, no par value (the "Stock"), in 
accordance with the terms and provisions thereof; and

      WHEREAS, the Committee considers Employee to be a person who is 
eligible for a grant of incentive stock options under the Plan, and has 
determined that it would be in the best interest of the Company to grant the 
incentive stock option described herein.

      NOW, THEREFORE, for good and valuable consideration, the receipt and 
sufficiency of which is hereby acknowledged, the parties hereto hereby agree 
as follows:

           1.    GRANT OF OPTION.  Subject to the terms and conditions 
hereinafter set forth, the Company, with the approval and at the direction of 
the Committee, hereby grants to the Employee, as of the date hereof, an 
option (the "Option") to purchase 1,300 shares of Stock (the "Option Shares") 
at a price of $19.07 per share (the "Exercise Price"), representing the Fair 
Market Value per Share (or, if Employee is the owner of stock possessing more 
than 10 percent of the total combined voting power of all classes of stock of 
the Company, or its parent or subsidiary corporation, if any, 110% of the 
Fair Market Value per Share) as of the Date of Grant as determined by the 
Committee in accordance with the Plan.  The Option is intended by the parties 
hereto to be, and shall be treated as, an incentive stock option (as such 
term is defined under Section 422 of the Internal Revenue Code of 1986, as 
amended (the "Code")).

                                       1
<PAGE>

      2.   VESTING.  The Option shall be immediately vested and exercisable 
with respect to all of the Option Shares on the date hereof.

      3.   EXERCISE OF OPTION. The Option, to the extent vested, may be 
exercised as follows:

           (a)   The Employee may exercise the Option with respect to all or 
any part of the Option Shares then vested by giving the Secretary of the 
Company written notice (the "Notice") of intent to exercise.  The Notice 
shall specify the number of Option Shares to be exercised (which shall be an 
amount no less than 50 shares or the number of shares as to which the Option 
is then exercisable, if less than 50) and the date of the proposed exercise 
thereof (the "Exercise Date"), which date shall be at least ten (10) but no 
more than thirty (30) calendar days after the giving of such notice unless an 
earlier time shall have been mutually agreed upon.

           (b)   Full payment (in U.S. dollars) by the Employee of the 
Exercise Price shall be made on or before the Exercise Date in cash or 
certified check.

           (c)   On or before the Exercise Date, Employee and his spouse, if 
any, shall execute and deliver to the Company an agreement restricting the 
transferability of the Option Shares substantially in the form of Exhibit A 
attached hereto (the "Right of First Refusal Agreement");

           (d)   On the Exercise Date or as soon thereafter as practicable 
thereafter, the Company shall cause to be delivered to the Employee a 
certificate or certificates for the Option Shares then being purchased upon 
full payment for such Option Shares.  Such certificate or certificates shall 
bear a restrictive legend in the form set forth in the Right of First Refusal 
Agreement.  The obligation of the Company to deliver the Option Shares shall, 
however, be subject to the condition that if at any time the Committee shall 
determine in its discretion that the listing, registration or qualification 
of the Option or the Option Shares upon any securities exchange or under any 
state or federal law, or the consent or approval of any governmental 
regulatory body, is necessary or desirable as a condition of, or in 
connection with, the Option or the issuance or purchase of Stock thereunder, 
the Option may not be exercised in whole or in part unless such listing, 
registration, qualification, consent or approval shall have been effected or 
obtained free of any conditions not 

                                       2
<PAGE>

acceptable to the Committee.

           (e)   If Employee fails to pay the Exercise Price by the Exercise 
Date for any of the Option Shares specified in the Notice or fails to deliver 
the Right of First Refusal Agreement, the Employee's right to purchase such 
Option Shares may be terminated by the Company upon written notice to 
Employee.  

      4.   TERMINATION OF OPTION.  The Option, and all rights hereunder with 
respect thereto, to the extent such rights shall not have been exercised, 
shall terminate and become null and void on the earliest to occur of the 
following dates as follows:

           (a)   the tenth (10th) anniversary date of the date hereof, or, if 
Employee is the owner of stock possessing more than 10 percent of the total 
combined voting power of all classes of stock of the Company, or its parent 
or subsidiary corporation, if any, the fifth (5th) anniversary date of the 
date hereof (the "Expiration Date");

           (b)   in the event Employee's employment with the Company or any 
subsidiary is terminated, other than by reason of death or Disability (as 
defined below) or termination for Cause (as defined below), then (i) this 
Option shall continue to vest and shall be exercisable as though Employee's 
employment with the Company continued for a period of two (2) years following 
the date of termination of employment, and (ii) this Option shall terminate 
and shall no longer be exercisable after the passage of two (2) years from 
the date of termination of employment, but in no event later than the 
Expiration Date (and further provided that in the event this Option is 
exercised following the expiration of three (3) months from the date of 
termination of employment, the portion of this Option so exercised will be 
treated as a non-qualified option as required by the Code).  In such a case, 
the Employee's only rights hereunder shall be those which have been properly 
exercised prior to the termination or earlier expiration of this Option;

           (c)   in the event Employee's employment with the Company or any 
subsidiary is terminated for Cause (as defined below), then no further 
installments of this Option shall vest or otherwise become exercisable, if 
such termination occurs during the Vesting Period, and this Option shall 
terminate and shall no longer be exercisable effective on the date of such 
termination. For purposes hereof, the term "Cause" shall mean conduct 
involving one or more of the following as determined by the Committee in its 
reasonable discretion: (i) the substantial and continuing failure 

                                       3
<PAGE>

of the Employee, after notice thereof, to render services to the Company or 
any subsidiary in accordance with the terms or requirements of the Employee's 
employment with the Company or any subsidiary; (ii) disloyalty, gross 
negligence, willful misconduct, dishonesty or breach of fiduciary duty to the 
Company or any subsidiary; (iii) the commission of an act of embezzlement or 
fraud; (iv) deliberate disregard of the rules or policies of the Company 
which results in direct or indirect loss, damage or injury to the Company or 
any subsidiary; (v) the unauthorized disclosure of any trade secret or 
confidential information of the Company or any subsidiary; or (vi) the 
commission of an act which constitutes unfair competition with the Company or 
any subsidiary or which induces any customer or supplier to break a contract 
with the Company or any subsidiary;

           (d)   in the event Employee dies while employed with the Company 
or any subsidiary, this Option may be exercised, to the extent vested on the 
date of his death, by the Employee's executor, estate, personal 
representative or beneficiary, as the case may be, and to whom this Option is 
transferred by operation of law, at any time within one (1) year after the 
date of death, but not later than the Expiration Date.  Following the 
expiration of such one-year period, this Option shall terminate;

           (e)   in the event Employee's employment with the Company or any 
subsidiary is terminated by reason of his Disability (which shall mean 
"permanent and total disability" as defined in Section 22(e)(3) of the Code, 
or any successor statute), this Option may be exercised, to the extent vested 
on the date of such Disability, at any time within one (1) year after the 
date of such Disability, but not later than Expiration Date.  Following the 
expiration of such one-year period, this Option shall terminate;

           (f)   the closing date of any Capital Transaction (as defined in 
Section 6 hereof); or

           (g)   the date the Company gives written notice to Employee of 
Employee's failure to pay the Exercise Price as provided in Section 3(e) 
hereof.

      5.   ADJUSTMENT OF AND CHANGES IN STOCK OF THE COMPANY.    In the event 
of a reorganization, recapitalization, change of shares, stock split, 
spin-off, stock dividend, reclassification, subdivision or combination of 
shares, merger, consolidation, rights offering, or any other change in the 
corporate structure or shares of capital stock of the Company, the Committee 
shall make 

                                       4
<PAGE>

such adjustment as it deems appropriate in the number and kind of shares of 
Stock subject to the Option or in the Exercise Price; PROVIDED HOWEVER, that 
no such adjustment shall give the Employee any additional benefits under the 
Option.

      6.   CAPITAL TRANSACTIONS.  In the event that following the date of 
this Agreement during the term hereof and prior to the termination of the 
Option in accordance with Section 4 hereof, there shall occur (a) a merger or 
consolidation of the Company with or into another corporation in which the 
Company shall not be the surviving corporation (for purposes of this Section 
6, the Company shall not be deemed the surviving corporation in any such 
transaction if, as the result thereof, it becomes a wholly-owned subsidiary 
of another corporation), (b) a dissolution of the Company, (c) a transfer of 
all or substantially all of the assets or shares of stock of the Company in 
one transaction or a series of related transactions to one or more other 
persons or entities, or (d) a distribution of the Company's equity securities 
to the public pursuant to a registration statement filed under the Securities 
Act of 1933, as amended, or any successor statute (any such transaction being 
referred to herein as a "Capital Transaction"), then the Company shall 
provide Employee with thirty (30) days advance written notice of such 
transaction and Employee, without the necessity of any further action by the 
Committee, shall be entitled to purchase, prior to the effective date of such 
Capital Transaction and in addition to the number of Option Shares which 
Employee shall be entitled to purchase as determined under Section 2 hereof, 
the number of remaining Option Shares which have not then become vested.  The 
unexercised portion of the Option shall be deemed cancelled and terminated as 
of the effective date of such transaction.

      7.   RIGHTS OF SHAREHOLDER.  Neither the Employee nor any heir, 
personal representative or other person shall be, or shall have any of the 
rights and privileges of, a shareholder of the Company with respect to any 
shares of Stock purchasable or issuable upon the exercise of the Option, in 
whole or in part, prior to the date of exercise of the Option.

      8.   TRANSFERABILITY OF OPTION.  During Employee's lifetime, the Option 
hereunder shall be exercisable only by the Employee or any guardian or legal 
representative of the Employee, and the Option shall not be transferable 
except, in case of the death of the Employee, by will or the laws of descent 
and distribution, nor shall the Option be subject to attachment, execution or 
other similar process.  In the event of (a) any attempt by Employee to 
alienate, assign, pledge, hypothecate or otherwise dispose of the 

                                       5
<PAGE>

Option, except as provided for herein, or (b) the levy of any attachment, 
execution or similar process upon the rights or interest hereby conferred, 
the Company may terminate the Option by notice to the Employee and it shall 
thereupon become null and void.

      9.   EMPLOYMENT NOT AFFECTED.  Neither the granting of the Option nor 
its exercise shall be construed as granting to the Employee any right with 
respect to continuance of employment.  Except as may otherwise be limited by 
a written agreement between the Company or one of its subsidiaries, as the 
case may be, and the Employee, the right of the Company (or one of its 
subsidiaries) to terminate the Employee's employment at any time is 
specifically reserved.

      10.  AMENDMENT OF OPTION.  The Option and this Agreement may be amended 
by the Board or the Committee at any time without the consent of Employee (i) 
if the Board or the Committee determines, in its sole discretion, that the 
amendment is necessary or advisable in the light of any addition to or change 
in the Code or in the regulations issued thereunder, or any federal or state 
securities law or other law or regulation, which change occurs after the date 
hereof and by its terms applies to the Option; or (ii) in order to make the 
adjustments set forth in Section 5 hereof.  Other than the matters set forth 
in the preceding sentence, the consent of Employee shall be required in order 
to amend any other provision of this Agreement.  Notwithstanding the 
foregoing, the Committee may, in its sole discretion, accelerate the 
exercisability of the Option at any time.

      11.   NOTICES. Any notice to the Company provided for in this Agreement 
shall be addressed to it in care of its Secretary at the Company's executive 
offices. Any notice to the Employee shall be addressed to Employee at the 
current address shown on the payroll records of the Company.  Any notice 
shall be deemed to be duly given if and when properly addressed and posted by 
registered or certified mail, postage prepaid.

      12.  INCORPORATION OF PLAN BY REFERENCE. The Option is granted pursuant 
to the terms of the Plan, the terms of which are incorporated herein by 
reference, and the Option shall in all respects be interpreted in accordance 
with the Plan.  The Committee shall interpret and construe the Plan and this 
Agreement, and its interpretations and determinations shall be conclusive and 
binding on the parties hereto and any other person claiming an interest 
hereunder, with respect to any issue arising hereunder or thereunder.  In the 
event any of the terms and 

                                       6
<PAGE>

conditions set forth in this Agreement are in conflict or are inconsistent 
with the terms of the Plan, the terms of the Plan shall control. 

      13.  GOVERNING LAW.  The validity, construction, interpretation and 
effect of this instrument shall exclusively be governed by and determined in 
accordance with the law of the State of Texas.

      14.  CAPITALIZED TERMS.  Unless otherwise defined herein, each 
capitalized term appearing in this Agreement shall have the same meaning as 
the corresponding term in the Plan.    

      15.  BINDING EFFECT.  This Agreement shall be binding upon the parties 
hereto, together with their respective executors, administrators, successors, 
personal representatives, heirs and assigns.

      16.  ENTIRE AGREEMENT.  This Agreement embodies the entire agreement 
and understanding between the parties hereto with respect to the subject 
matter hereof and supersedes all prior agreements and understandings relating 
to the subject matter hereof (including but not limited to those certain 
letter agreements dated December 20, 1994 and September 13, 1996 between 
Antinori Software, Inc. and Employee, which are hereby terminated effective 
as of the date hereof).

      17.  COUNTERPARTS.  This Agreement may be executed in counterparts, 
each of which shall be deemed an original, but all of which together shall 
constitute one instrument.

      IN WITNESS WHEREOF, the undersigned have executed this Agreement as of 
the date first above written.

           1.    GRANT OF OPTION.  Subject to the terms and conditions 
hereinafter set forth, the Company, with the approval and at the direction of 
the Committee, hereby grants to the Employee, as of the date hereof, an 
option (the "Option") to purchase 5,146 shares of Stock (the "Option Shares") 
at a price of $17.53 per share (the "Exercise Price").  The Option is not 
intended by the parties hereto to be, and shall not be treated as, an 
incentive stock option (as such term is defined under Section 422 of the 
Internal Revenue Code of 1986, as amended (the "Code")).

      2.   VESTING.  The Option shall vest and become exercisable during the 
period commencing on the date hereof and ending on April 1, 1999 (herein the 
"Vesting Period") as follows:

           (a)   The Option shall vest and shall become exercisable with 
respect to one-third (1/3) of the Option Shares on April 1, 1997, provided 
Employee is employed by the Company or one of its subsidiaries as of such 
date and has been continuously employed during the term of this Agreement, 
and further provided that the Option has not otherwise terminated in 
accordance with the terms of Section 4 hereof;

                                       1
<PAGE>

           (b)   The Option shall vest and shall be exercisable with respect 
to an additional one-third (1/3) of the Option Shares on April 1, 1998, 
provided Employee is employed by the Company or one of its subsidiaries as of 
such date and has been continuously employed during the term of this 
Agreement, and further provided that the Option has not otherwise terminated 
in accordance with the terms of Section 4 hereof; and
      
           (c)   The Option shall vest and shall be exercisable with respect 
to the remaining one-third (1/3) of the Option Shares on April 1, 1999, 
provided Employee is employed by the Company or one of its subsidiaries as of 
such date and has been continuously employed by the Company or one of its 
subsidiaries during the term of this Agreement, and further provided that the 
Option has not otherwise terminated in accordance with the terms of Section 4 
hereof.

      3.   EXERCISE OF OPTION. The Option, to the extent vested, may be
exercised as follows:

           (a)   The Employee may exercise the Option with respect to all or 
any part of the Option Shares then vested by giving the Secretary of the 
Company written notice (the "Notice") of intent to exercise.  The Notice 
shall specify the number of Option Shares to be exercised (which shall be an 
amount no less than 50 shares or the number of shares as to which the Option 
is then exercisable, if less than 50) and the date of the proposed exercise 
thereof (the "Exercise Date"), which date shall be at least ten (10) but no 
more than thirty (30) calendar days after the giving of such notice unless an 
earlier time shall have been mutually agreed upon.

           (b)   Full payment (in U.S. dollars) by the Employee of the 
Exercise Price shall be made on or before the Exercise Date in cash or 
certified check.

           (c)   On or before the Exercise Date, Employee and his spouse, if 
any, shall execute and deliver to the Company an agreement restricting the 
transferability of the Option Shares substantially in the form of Exhibit A 
attached hereto (the "Right of First Refusal Agreement");

           (d)   On the Exercise Date or as soon thereafter as practicable 
thereafter, the Company shall cause to be delivered to the Employee a 
certificate or certificates for the Option Shares then being purchased upon 
full payment for such Option Shares.  

                                       2
<PAGE>

Such certificate or certificates shall bear a restrictive legend in the form 
set forth in the Right of First Refusal Agreement.  The obligation of the 
Company to deliver the Option Shares shall, however, be subject to the 
condition that if at any time the Committee shall determine in its discretion 
that the listing, registration or qualification of the Option or the Option 
Shares upon any securities exchange or under any state or federal law, or the 
consent or approval of any governmental regulatory body, is necessary or 
desirable as a condition of, or in connection with, the Option or the 
issuance or purchase of Stock thereunder, the Option may not be exercised in 
whole or in part unless such listing, registration, qualification, consent or 
approval shall have been effected or obtained free of any conditions not 
acceptable to the Committee.

           (e)   If Employee fails to pay the Exercise Price by the Exercise 
Date for any of the Option Shares specified in the Notice or fails to deliver 
the Right of First Refusal Agreement, the Employee's right to purchase such 
Option Shares may be terminated by the Company upon written notice to 
Employee.  

      4.   TERMINATION OF OPTION.  The Option, and all rights hereunder with 
respect thereto, to the extent such rights shall not have been exercised, 
shall terminate and become null and void on the earliest to occur of the 
following dates as follows:

           (a)   the tenth (10th) anniversary date of the date hereof (the 
"Expiration Date");

           (b)   the date Employee ceases for any reason to be employed by 
the Company or one of its subsidiaries, other than by reason of death or 
Disability (as defined below). For purposes hereof, a transfer of Employee's 
employment between the Company and any subsidiary of the Company, or between 
any subsidiaries of the Company, shall not be deemed to be a termination of 
the Employee's employment.  

           (c)   in the event Employee dies while employed with the Company 
or any subsidiary, this Option may be exercised, to the extent vested on the 
date of his death, by the Employee's executor, estate, personal 
representative or beneficiary, as the case may be, and to whom this Option is 
transferred by operation of law, at any time within one (1) year after the 
date of death, but not later than the Expiration Date.  Following the 
expiration of such one-year period, this Option shall terminate;

           (d)   in the event Employee's employment with the 

                                       3
<PAGE>

Company or any subsidiary is terminated by reason of his Disability (which 
shall mean "permanent and total disability" as defined in Section 22(e)(3) of 
the Code, or any successor statute), this Option may be exercised, to the 
extent vested on the date of such Disability, at any time within one (1) year 
after the date of such Disability, but not later than Expiration Date.  
Following the expiration of such one-year period, this Option shall terminate;

           (e)   the closing date of any Capital Transaction (as defined in 
Section 6 hereof); or

           (f)   the date the Company gives written notice to Employee of 
Employee's failure to pay the Exercise Price as provided in Section 3(e) 
hereof.

      5.   ADJUSTMENT OF AND CHANGES IN STOCK OF THE COMPANY.  In the event 
of a reorganization, recapitalization, change of shares, stock split, 
spin-off, stock dividend, reclassification, subdivision or combination of 
shares, merger, consolidation, rights offering, or any other change in the 
corporate structure or shares of capital stock of the Company, the Committee 
shall make such adjustment as it deems appropriate in the number and kind of 
shares of Stock subject to the Option or in the Exercise Price; PROVIDED 
HOWEVER, that no such adjustment shall give the Employee any additional 
benefits under the Option.

      6.   CAPITAL TRANSACTIONS.  In the event that following the date of 
this Agreement during the term hereof and prior to the termination of the 
Option in accordance with Section 4 hereof, there shall occur (a) a merger or 
consolidation of the Company with or into another corporation in which the 
Company shall not be the surviving corporation (for purposes of this Section 
6, the Company shall not be deemed the surviving corporation in any such 
transaction if, as the result thereof, it becomes a wholly-owned subsidiary 
of another corporation), (b) a dissolution of the Company, (c) a transfer of 
all or substantially all of the assets or shares of stock of the Company in 
one transaction or a series of related transactions to one or more other 
persons or entities, or (d) a distribution of the Company's equity securities 
to the public pursuant to a registration statement filed under the Securities 
Act of 1933, as amended, or any successor statute (any such transaction being 
referred to herein as a "Capital Transaction"), then the Company shall 
provide Employee with thirty (30) days advance written notice of such 
transaction and Employee, without the necessity of any further action by the 
Committee, shall be entitled to purchase, prior to the effective date of such 

                                       4
<PAGE>

Capital Transaction and in addition to the number of Option Shares which 
Employee shall be entitled to purchase as determined under Section 2 hereof, 
the number of remaining Option Shares which have not then become vested.  The 
unexercised portion of the Option shall be deemed cancelled and terminated as 
of the effective date of such transaction.

      7.   RIGHTS OF SHAREHOLDER.  Neither the Employee nor any heir, 
personal representative or other person shall be, or shall have any of the 
rights and privileges of, a shareholder of the Company with respect to any 
shares of Stock purchasable or issuable upon the exercise of the Option, in 
whole or in part, prior to the date of exercise of the Option.

      8.   TRANSFERABILITY OF OPTION.  During Employee's lifetime, the Option 
hereunder shall be exercisable only by the Employee or any guardian or legal 
representative of the Employee, and the Option shall not be transferable 
except, in case of the death of the Employee, by will or the laws of descent 
and distribution, nor shall the Option be subject to attachment, execution or 
other similar process.  In the event of (a) any attempt by Employee to 
alienate, assign, pledge, hypothecate or otherwise dispose of the Option, 
except as provided for herein, or (b) the levy of any attachment, execution 
or similar process upon the rights or interest hereby conferred, the Company 
may terminate the Option by notice to the Employee and it shall thereupon 
become null and void.

      9.   EMPLOYMENT NOT AFFECTED.  Neither the granting of the Option nor 
its exercise shall be construed as granting to the Employee any right with 
respect to continuance of employment.  Except as may otherwise be limited by 
a written agreement between the Company or one of its subsidiaries, as the 
case may be, and the Employee, the right of the Company (or one of its 
subsidiaries) to terminate the Employee's employment at any time is 
specifically reserved.

      10.  AMENDMENT OF OPTION.  The Option and this Agreement may be amended 
by the Board or the Committee at any time without the consent of Employee (i) 
if the Board or the Committee determines, in its sole discretion, that the 
amendment is necessary or advisable in the light of any addition to or change 
in the Code or in the regulations issued thereunder, or any federal or state 
securities law or other law or regulation, which change occurs after the date 
hereof and by its terms applies to the Option; or (ii) in order to make the 
adjustments set forth in Section 5 hereof.  Other than the matters set forth 
in the preceding 

                                       5
<PAGE>

sentence, the consent of Employee shall be required in order to amend any 
other provision of this Agreement.  Notwithstanding the foregoing, the 
Committee may, in its sole discretion, accelerate the exercisability of the 
Option at any time.

      11.   NOTICES. Any notice to the Company provided for in this Agreement 
shall be addressed to it in care of its Secretary at the Company's executive 
offices. Any notice to the Employee shall be addressed to Employee at the 
current address shown on the payroll records of the Company.  Any notice 
shall be deemed to be duly given if and when properly addressed and posted by 
registered or certified mail, postage prepaid.

      12.  INCORPORATION OF PLAN BY REFERENCE. The Option is granted pursuant 
to the terms of the Plan, the terms of which are incorporated herein by 
reference, and the Option shall in all respects be interpreted in accordance 
with the Plan.  The Committee shall interpret and construe the Plan and this 
Agreement, and its interpretations and determinations shall be conclusive and 
binding on the parties hereto and any other person claiming an interest 
hereunder, with respect to any issue arising hereunder or thereunder.  In the 
event any of the terms and conditions set forth in this Agreement are in 
conflict or are inconsistent with the terms of the Plan, the terms of the 
Plan shall control. 

      13.  GOVERNING LAW.  The validity, construction, interpretation and 
effect of this instrument shall exclusively be governed by and determined in 
accordance with the law of the State of Texas.

      14.  CAPITALIZED TERMS.  Unless otherwise defined herein, each 
capitalized term appearing in this Agreement shall have the same meaning as 
the corresponding term in the Plan.    

      15.  BINDING EFFECT.  This Agreement shall be binding upon the parties 
hereto, together with their respective executors, administrators, successors, 
personal representatives, heirs and assigns.

      16.  ENTIRE AGREEMENT.  This Agreement embodies the entire agreement 
and understanding between the parties hereto with respect to the subject 
matter hereof and supersedes all prior agreements and understandings relating 
to the subject matter hereof (including but not limited to that certain 
agreement dated March 8, 1996 between Antinori Software, Inc. and Employee, 
which is hereby terminated effective as of the date hereof).

                            THE CARREKER GROUP, INC.
                         1994 LONG TERM INCENTIVE PLAN

                      NON-QUALIFIED STOCK OPTION AGREEMENT
                       (CLASS B NON-VOTING COMMON STOCK)

      This Agreement ("Agreement") is dated this __________ day of January, 
1997 by and among The Carreker Group, Inc., a Texas corporation (the 
"Company") and Lawrence D. Duckworth ("Employee").

      WHEREAS, the Board of Directors of the Company (the "Board") has 
adopted, and the shareholders of the Company have approved, The Carreker 
Group, Inc. Amended and Restated 1994 Long Term Incentive Plan (the "Plan");

      WHEREAS, the Plan provides for the granting of non-qualified stock 
options by the Compensation Committee of the Board or any successor committee 
thereto (the "Committee") to officers and key employees of the Company or any 
subsidiary of the Company and its subsidiaries to purchase shares of the 
Company's Class B Non-Voting Common Stock, no par value (the "Stock"), in 
accordance with the terms and provisions thereof; and

      WHEREAS, the Committee considers Employee to be a person who is 
eligible for a grant of non-qualified stock options under the Plan, and has 
determined that it would be in the best interest of the Company to grant the 
non-qualified stock option described herein.

      NOW, THEREFORE, for good and valuable consideration, the receipt and 
sufficiency of which is hereby acknowledged, the parties hereto hereby agree 
as follows:

           1.    GRANT OF OPTION.  Subject to the terms and conditions 
hereinafter set forth, the Company, with the approval and at the direction of 
the Committee, hereby grants to the Employee, as of the date hereof, an 
option (the "Option") to purchase 17,580 shares of Stock (the "Option 
Shares") at a price of $19.07 per share (the "Exercise Price").  The Option 
is not intended by the parties hereto to be, and shall not be treated as, an 
incentive stock option (as such term is defined under Section 422 of the 
Internal Revenue Code of 1986, as amended (the "Code")).

      2.   VESTING.  The Option shall vest and become exercisable during the 
two-year period following the date hereof (herein the "Vesting Period") as 
follows:

           (a)   The Option shall be immediately vested and exercisable with 
respect to one-third (1/3) of the Option Shares on the date hereof;

                                       1
<PAGE>

           (b)   The Option shall vest and shall be exercisable with respect 
to an additional one-third (1/3) of the Option Shares on the first 
anniversary date of this Agreement, provided Employee is employed by the 
Company or one of its subsidiaries as of such date and has been continuously 
employed during the term of this Agreement, and further provided that the 
Option has not otherwise terminated in accordance with the terms of Section 4 
hereof; and
      
           (c)   The Option shall vest and shall be exercisable with respect 
to the remaining one-third (1/3) of the Option Shares on the second 
anniversary date of this Agreement, provided Employee is employed by the 
Company or one of its subsidiaries as of such date and has been continuously 
employed by the Company or one of its subsidiaries during the term of this 
Agreement, and further provided that the Option has not otherwise terminated 
in accordance with the terms of Section 4 hereof.

      3.   EXERCISE OF OPTION. The Option, to the extent vested, may be 
exercised as follows:

           (a)   The Employee may exercise the Option with respect to all or 
any part of the Option Shares then vested by giving the Secretary of the 
Company written notice (the "Notice") of intent to exercise.  The Notice 
shall specify the number of Option Shares to be exercised (which shall be an 
amount no less than 50 shares or the number of shares as to which the Option 
is then exercisable, if less than 50) and the date of the proposed exercise 
thereof (the "Exercise Date"), which date shall be at least ten (10) but no 
more than thirty (30) calendar days after the giving of such notice unless an 
earlier time shall have been mutually agreed upon.

           (b)   Full payment (in U.S. dollars) by the Employee of the 
Exercise Price shall be made on or before the Exercise Date in cash or 
certified check.

           (c)   On or before the Exercise Date, Employee and his spouse, if 
any, shall execute and deliver to the Company an agreement restricting the 
transferability of the Option Shares substantially in the form of Exhibit A 
attached hereto (the "Right of First Refusal Agreement");

           (d)   On the Exercise Date or as soon thereafter as practicable 
thereafter, the Company shall cause to be delivered to the Employee a 
certificate or certificates for the Option Shares then being purchased upon 
full payment for such Option Shares.  Such certificate or certificates shall 
bear a restrictive legend 

                                       2
<PAGE>

in the form set forth in the Right of First Refusal Agreement.  The 
obligation of the Company to deliver the Option Shares shall, however, be 
subject to the condition that if at any time the Committee shall determine in 
its discretion that the listing, registration or qualification of the Option 
or the Option Shares upon any securities exchange or under any state or 
federal law, or the consent or approval of any governmental regulatory body, 
is necessary or desirable as a condition of, or in connection with, the 
Option or the issuance or purchase of Stock thereunder, the Option may not be 
exercised in whole or in part unless such listing, registration, 
qualification, consent or approval shall have been effected or obtained free 
of any conditions not acceptable to the Committee.

           (e)   If Employee fails to pay the Exercise Price by the Exercise 
Date for any of the Option Shares specified in the Notice or fails to deliver 
the Right of First Refusal Agreement, the Employee's right to purchase such 
Option Shares may be terminated by the Company upon written notice to 
Employee.  

      4.   TERMINATION OF OPTION.  The Option, and all rights hereunder with 
respect thereto, to the extent such rights shall not have been exercised, 
shall terminate and become null and void on the earliest to occur of the 
following dates as follows:

           (a)   the tenth (10th) anniversary date of the date hereof (the 
"Expiration Date");

           (b)   in the event Employee's employment with the Company or any 
subsidiary is terminated, other than by reason of death or Disability (as 
defined below) or termination for Cause (as defined below), then (i) this 
Option shall continue to vest and shall be exercisable as though Employee's 
employment with the Company continued for a period of two (2) years following 
the date of termination of employment, and (ii) this Option shall terminate 
and shall no longer be exercisable after the passage of two (2) years from 
the date of termination of employment, but in no event later than the 
Expiration Date.  In such a case, the Employee's only rights hereunder shall 
be those which have been properly exercised prior to the termination or 
earlier expiration of this Option;

           (c)   in the event Employee's employment with the Company or any 
subsidiary is terminated for Cause (as defined below), then no further 
installments of this Option shall vest or otherwise become exercisable, if 
such termination occurs during the Vesting Period, and this Option shall 
terminate and shall no 

                                       3
<PAGE>

longer be exercisable effective on the date of such termination. For purposes 
hereof, the term "Cause" shall mean conduct involving one or more of the 
following as determined by the Committee in its reasonable discretion: (i) 
the substantial and continuing failure of the Employee, after notice thereof, 
to render services to the Company or any subsidiary in accordance with the 
terms or requirements of the Employee's employment with the Company or any 
subsidiary; (ii) disloyalty, gross negligence, willful misconduct, dishonesty 
or breach of fiduciary duty to the Company or any subsidiary; (iii) the 
commission of an act of embezzlement or fraud; (iv) deliberate disregard of 
the rules or policies of the Company which results in direct or indirect 
loss, damage or injury to the Company or any subsidiary; (v) the unauthorized 
disclosure of any trade secret or confidential information of the Company or 
any subsidiary; or (vi) the commission of an act which constitutes unfair 
competition with the Company or any subsidiary or which induces any customer 
or supplier to break a contract with the Company or any subsidiary;

           (d)   in the event Employee dies while employed with the Company 
or any subsidiary, this Option may be exercised by the Employee's executor, 
estate, personal representative or beneficiary, as the case may be, and to 
whom this Option is transferred by operation of law, at any time within two 
(2) years after the date of death, but not later than the Expiration Date.  
This Option shall continue to vest following the date of death of Employee as 
though Employee were employed by the Company for a period of two (2) years 
following the date of death.  Following the expiration of such two-year 
period, this Option shall terminate;

           (e)   in the event Employee's employment with the Company or any 
subsidiary is terminated by reason of his Disability (which shall mean 
"permanent and total disability" as defined in Section 22(e)(3) of the Code, 
or any successor statute), this Option may be exercised at any time within 
two (2) years after the date of such Disability, but not later than 
Expiration Date. This Option shall continue to vest following the date of 
Disability of Employee as though Employee were employed by the Company for a 
period of two (2) years following the date of Disability.  Following the 
expiration of such two-year period, this Option shall terminate;

           (f)   the closing date of any Capital Transaction (as defined in 
Section 6 hereof); or

           (g)   the date the Company gives written notice to 

                                       4
<PAGE>

Employee of Employee's failure to pay the Exercise Price as provided in 
Section 3(e) hereof.

      5.   ADJUSTMENT OF AND CHANGES IN STOCK OF THE COMPANY.  In the event 
of a reorganization, recapitalization, change of shares, stock split, 
spin-off, stock dividend, reclassification, subdivision or combination of 
shares, merger, consolidation, rights offering, or any other change in the 
corporate structure or shares of capital stock of the Company, the Committee 
shall make such adjustment as it deems appropriate in the number and kind of 
shares of Stock subject to the Option or in the Exercise Price; PROVIDED 
HOWEVER, that no such adjustment shall give the Employee any additional 
benefits under the Option.

      6.   CAPITAL TRANSACTIONS.  In the event that following the date of 
this Agreement during the term hereof and prior to the termination of the 
Option in accordance with Section 4 hereof, there shall occur (a) a merger or 
consolidation of the Company with or into another corporation in which the 
Company shall not be the surviving corporation (for purposes of this Section 
6, the Company shall not be deemed the surviving corporation in any such 
transaction if, as the result thereof, it becomes a wholly-owned subsidiary 
of another corporation), (b) a dissolution of the Company, (c) a transfer of 
all or substantially all of the assets or shares of stock of the Company in 
one transaction or a series of related transactions to one or more other 
persons or entities, or (d) a distribution of the Company's equity securities 
to the public pursuant to a registration statement filed under the Securities 
Act of 1933, as amended, or any successor statute (any such transaction being 
referred to herein as a "Capital Transaction"), then the Company shall 
provide Employee with thirty (30) days advance written notice of such 
transaction and Employee, without the necessity of any further action by the 
Committee, shall be entitled to purchase, prior to the effective date of such 
Capital Transaction and in addition to the number of Option Shares which 
Employee shall be entitled to purchase as determined under Section 2 hereof, 
the number of remaining Option Shares which have not then become vested.  The 
unexercised portion of the Option shall be deemed cancelled and terminated as 
of the effective date of such transaction.

      7.   RIGHTS OF SHAREHOLDER.  Neither the Employee nor any heir, 
personal representative or other person shall be, or shall have any of the 
rights and privileges of, a shareholder of the Company with respect to any 
shares of Stock purchasable or issuable upon the exercise of the Option, in 
whole or in part, prior to the date of exercise of the Option.

      8.   TRANSFERABILITY OF OPTION.  During Employee's lifetime, the Option 
hereunder shall be exercisable only by the Employee or any guardian or legal 
representative of the Employee, and the Option shall not be transferable 
except, in case of the death of the Employee, by will or the laws of descent 
and distribution, nor shall the Option be subject to attachment, execution or 
other similar process.  In the event of (a) any attempt by Employee to 
alienate, assign, pledge, hypothecate or otherwise dispose of the Option, 
except as provided for herein, or (b) the levy of any attachment, execution 
or similar process upon the rights or interest hereby conferred, the Company 
may terminate the Option by notice to the Employee and it shall thereupon 
become null and void.

      9.   EMPLOYMENT NOT AFFECTED.  Neither the granting of the Option nor 
its exercise shall be construed as granting to the Employee any right with 
respect to continuance of employment.  Except as may otherwise be limited by 
a written agreement between the Company or one of its subsidiaries, as the 
case may be, and the Employee, the right of the Company (or one of its 
subsidiaries) to terminate the Employee's employment at any time is 
specifically reserved.

      10.  AMENDMENT OF OPTION.  The Option and this Agreement may be amended 
by the Board or the Committee at any time without the consent of Employee (i) 
if the Board or the Committee determines, in its sole discretion, that the 
amendment is necessary or advisable in the light of any addition to or change 
in the Code or in the regulations issued thereunder, or any federal or state 
securities law or other law or regulation, which change occurs after the date 
hereof and by its terms applies to the Option; or (ii) in order to make the 
adjustments set forth in Section 5 hereof.  Other than the matters set forth 
in the preceding sentence, the consent of Employee shall be required in order 
to amend any other provision of this Agreement.  Notwithstanding the 
foregoing, the Committee may, in its sole discretion, accelerate the 
exercisability of the Option at any time.

      11.   NOTICES. Any notice to the Company provided for in this Agreement 
shall be addressed to it in care of its Secretary at the Company's executive 
offices. Any notice to the Employee shall be addressed to Employee at the 
current address shown on the payroll records of the Company.  Any notice 
shall be deemed to be duly given if and when properly addressed and posted by

agreement dated October 24, 1995 between Antinori Software, Inc. and 
Employee, which is hereby terminated effective as of the date hereof).

      17.  COUNTERPARTS.  This Agreement may be executed in counterparts, 
each of which shall be deemed an original, but all of which together shall 
constitute one instrument.

                            THE CARREKER GROUP, INC.
                         1994 LONG TERM INCENTIVE PLAN

                      NON-QUALIFIED STOCK OPTION AGREEMENT
                       (CLASS B NON-VOTING COMMON STOCK)

      This Agreement ("Agreement") is dated this ___________ day of January, 
1997 by and among The Carreker Group, Inc., a Texas corporation (the 
"Company") and Michael Israel ("Employee").

      WHEREAS, the Board of Directors of the Company (the "Board") has 
adopted, and the shareholders of the Company have approved, The Carreker 
Group, Inc. Amended and Restated 1994 Long Term Incentive Plan (the "Plan");

      WHEREAS, the Plan provides for the granting of non-qualified stock 
options by the Compensation Committee of the Board or any successor committee 
thereto (the "Committee") to officers and key employees of the Company or any 
subsidiary of the Company and its subsidiaries to purchase shares of the 
Company's Class B Non-Voting Common Stock, no par value (the "Stock"), in 
accordance with the terms and provisions thereof; and

      WHEREAS, the Committee considers Employee to be a person who is 
eligible for a grant of non-qualified stock options under the Plan, and has 
determined that it would be in the best interest of the Company to grant the 
non-qualified stock option described herein.

      NOW, THEREFORE, for good and valuable consideration, the receipt and 
sufficiency of which is hereby acknowledged, the parties hereto hereby agree 
as follows:

           1.    GRANT OF OPTION.  Subject to the terms and conditions 
hereinafter set forth, the Company, with the approval and at the direction of 
the Committee, hereby grants to the Employee, as of the date hereof, an 
option (the "Option") to purchase 7,380 shares of Stock (the "Option Shares") 
at a price of $19.07 per share (the "Exercise Price").  The Option is not 
intended by the parties hereto to be, and shall not be treated as, an 
incentive stock option (as such term is defined under Section 422 of the 
Internal Revenue Code of 1986, as amended (the "Code")).

                                       1
<PAGE>

      2.   VESTING.  The Option shall vest and become exercisable during the 
two-year period following the date hereof (herein the "Vesting Period") as 
follows:

           (a)   The Option shall be immediately vested and exercisable with 
respect to one-third (1/3) of the Option Shares on the date hereof;

           (b)   The Option shall vest and shall be exercisable with respect 
to an additional one-third (1/3) of the Option Shares on the first 
anniversary date of this Agreement, provided Employee is employed by the 
Company or one of its subsidiaries as of such date and has been continuously 
employed during the term of this Agreement, and further provided that the 
Option has not otherwise terminated in accordance with the terms of Section 4 
hereof; and
      
           (c)   The Option shall vest and shall be exercisable with respect 
to the remaining one-third (1/3) of the Option Shares on the second 
anniversary date of this Agreement, provided Employee is employed by the 
Company or one of its subsidiaries as of such date and has been continuously 
employed by the Company or one of its subsidiaries during the term of this 
Agreement, and further provided that the Option has not otherwise terminated 
in accordance with the terms of Section 4 hereof.

      3.   EXERCISE OF OPTION. The Option, to the extent vested, may be 
exercised as follows:

           (a)   The Employee may exercise the Option with respect to all or 
any part of the Option Shares then vested by giving the Secretary of the 
Company written notice (the "Notice") of intent to exercise.  The Notice 
shall specify the number of Option Shares to be exercised (which shall be an 
amount no less than 50 shares or the number of shares as to which the Option 
is then exercisable, if less than 50) and the date of the proposed exercise 
thereof (the "Exercise Date"), which date shall be at least ten (10) but no 
more than thirty (30) calendar days after the giving of such notice unless an 
earlier time shall have been mutually agreed upon.

           (b)   Full payment (in U.S. dollars) by the Employee of the 
Exercise Price shall be made on or before the Exercise Date in cash or 
certified check.

           (c)   On or before the Exercise Date, Employee and his spouse, if 
any, shall execute and deliver to the Company an agreement restricting the 
transferability of the Option Shares substantially in the form of Exhibit A 
attached hereto (the "Right of First Refusal Agreement");

           (d)   On the Exercise Date or as soon thereafter as practicable 
thereafter, the Company shall cause to be delivered to the Employee a 
certificate or certificates for the Option Shares then being purchased upon 
full payment for such Option Shares.  Such certificate or certificates shall 
bear a restrictive legend in the form set forth in the Right of First Refusal 
Agreement.  

                                       2
<PAGE>

The obligation of the Company to deliver the Option Shares shall, however, be 
subject to the condition that if at any time the Committee shall determine in 
its discretion that the listing, registration or qualification of the Option 
or the Option Shares upon any securities exchange or under any state or 
federal law, or the consent or approval of any governmental regulatory body, 
is necessary or desirable as a condition of, or in connection with, the 
Option or the issuance or purchase of Stock thereunder, the Option may not be 
exercised in whole or in part unless such listing, registration, 
qualification, consent or approval shall have been effected or obtained free 
of any conditions not acceptable to the Committee.

           (e)   If Employee fails to pay the Exercise Price by the Exercise 
Date for any of the Option Shares specified in the Notice or fails to deliver 
the Right of First Refusal Agreement, the Employee's right to purchase such 
Option Shares may be terminated by the Company upon written notice to 
Employee.  

      4.   TERMINATION OF OPTION.  The Option, and all rights hereunder with 
respect thereto, to the extent such rights shall not have been exercised, 
shall terminate and become null and void on the earliest to occur of the 
following dates as follows:

           (a)   the tenth (10th) anniversary date of the date hereof (the 
"Expiration Date");

           (b)   in the event Employee's employment with the Company or any 
subsidiary is terminated, other than by reason of death or Disability (as 
defined below) or termination for Cause (as defined below), then (i) this 
Option shall continue to vest and shall be exercisable as though Employee's 
employment with the Company continued for a period of two (2) years following 
the date of termination of employment, and (ii) this Option shall terminate 
and shall no longer be exercisable after the passage of two (2) years from 
the date of termination of employment, but in no event later than the 
Expiration Date.  In such a case, the Employee's only rights hereunder shall 
be those which have been properly exercised prior to the termination or 
earlier expiration of this Option;

           (c)   in the event Employee's employment with the Company or any 
subsidiary is terminated for Cause (as defined below), then no further 
installments of this Option shall vest or otherwise become exercisable, if 
such termination occurs during the Vesting Period, and this Option shall 
terminate and shall no longer be exercisable effective on the date of such 
termination. For purposes hereof, the term "Cause" shall mean conduct 
involving 

                                       3
<PAGE>

one or more of the following as determined by the Committee in its reasonable 
discretion: (i) the substantial and continuing failure of the Employee, after 
notice thereof, to render services to the Company or any subsidiary in 
accordance with the terms or requirements of the Employee's employment with 
the Company or any subsidiary; (ii) disloyalty, gross negligence, willful 
misconduct, dishonesty or breach of fiduciary duty to the Company or any 
subsidiary; (iii) the commission of an act of embezzlement or fraud; (iv) 
deliberate disregard of the rules or policies of the Company which results in 
direct or indirect loss, damage or injury to the Company or any subsidiary; 
(v) the unauthorized disclosure of any trade secret or confidential 
information of the Company or any subsidiary; or (vi) the commission of an 
act which constitutes unfair competition with the Company or any subsidiary 
or which induces any customer or supplier to break a contract with the 
Company or any subsidiary;

           (d)   in the event Employee dies while employed with the Company 
or any subsidiary, this Option may be exercised, by the Employee's executor, 
estate, personal representative or beneficiary, as the case may be, and to 
whom this Option is transferred by operation of law, at any time within two 
(2) years after the date of death, but not later than the Expiration Date.  
This Option shall continue to vest following the date of death of Employee as 
though Employee were employed by the Company for a period of two (2) years 
following the date of death.  Following the expiration of such two-year 
period, this Option shall terminate;

           (e)   in the event Employee's employment with the Company or any 
subsidiary is terminated by reason of his Disability (which shall mean 
"permanent and total disability" as defined in Section 22(e)(3) of the Code, 
or any successor statute), this Option may be exercised at any time within 
two (2) years after the date of such Disability, but not later than 
Expiration Date. This Option shall continue to vest following the date of 
Disability of Employee as though Employee were employed by the Company for a 
period of two (2) years following the date of Disability.  Following the 
expiration of such two-year period, this Option shall terminate;

           (f)   the closing date of any Capital Transaction (as defined in 
Section 6 hereof); or

           (g)   the date the Company gives written notice to Employee of 
Employee's failure to pay the Exercise Price as provided in Section 3(e) 
hereof.

                                       4
<PAGE>

      5.   ADJUSTMENT OF AND CHANGES IN STOCK OF THE COMPANY.    In the event 
of a reorganization, recapitalization, change of shares, stock split, 
spin-off, stock dividend, reclassification, subdivision or combination of 
shares, merger, consolidation, rights offering, or any other change in the 
corporate structure or shares of capital stock of the Company, the Committee 
shall make such adjustment as it deems appropriate in the number and kind of 
shares of Stock subject to the Option or in the Exercise Price; PROVIDED 
HOWEVER, that no such adjustment shall give the Employee any additional 
benefits under the Option.

      6.   CAPITAL TRANSACTIONS.  In the event that following the date of 
this Agreement during the term hereof and prior to the termination of the 
Option in accordance with Section 4 hereof, there shall occur (a) a merger or 
consolidation of the Company with or into another corporation in which the 
Company shall not be the surviving corporation (for purposes of this Section 
6, the Company shall not be deemed the surviving corporation in any such 
transaction if, as the result thereof, it becomes a wholly-owned subsidiary 
of another corporation), (b) a dissolution of the Company, (c) a transfer of 
all or substantially all of the assets or shares of stock of the Company in 
one transaction or a series of related transactions to one or more other 
persons or entities, or (d) a distribution of the Company's equity securities 
to the public pursuant to a registration statement filed under the Securities 
Act of 1933, as amended, or any successor statute (any such transaction being 
referred to herein as a "Capital Transaction"), then the Company shall 
provide Employee with thirty (30) days advance written notice of such 
transaction and Employee, without the necessity of any further action by the 
Committee, shall be entitled to purchase, prior to the effective date of such 
Capital Transaction and in addition to the number of Option Shares which 
Employee shall be entitled to purchase as determined under Section 2 hereof, 
the number of remaining Option Shares which have not then become vested.  The 
unexercised portion of the Option shall be deemed cancelled and terminated as 
of the effective date of such transaction.

      7.   RIGHTS OF SHAREHOLDER.  Neither the Employee nor any heir, 
personal representative or other person shall be, or shall have any of the 
rights and privileges of, a shareholder of the Company with respect to any 
shares of Stock purchasable or issuable upon the exercise of the Option, in 
whole or in part, prior to the date of exercise of the Option.

      8.   TRANSFERABILITY OF OPTION.  During Employee's lifetime, the Option 
hereunder shall be exercisable only by the Employee or any guardian or legal 
representative of the Employee, and the 

                                       5
<PAGE>

Option shall not be transferable except, in case of the death of the 
Employee, by will or the laws of descent and distribution, nor shall the 
Option be subject to attachment, execution or other similar process.  In the 
event of (a) any attempt by Employee to alienate, assign, pledge, hypothecate 
or otherwise dispose of the Option, except as provided for herein, or (b) the 
levy of any attachment, execution or similar process upon the rights or 
interest hereby conferred, the Company may terminate the Option by notice to 
the Employee and it shall thereupon become null and void.

      9.   EMPLOYMENT NOT AFFECTED.  Neither the granting of the Option nor 
its exercise shall be construed as granting to the Employee any right with 
respect to continuance of employment.  Except as may otherwise be limited by 
a written agreement between the Company or one of its subsidiaries, as the 
case may be, and the Employee, the right of the Company (or one of its 
subsidiaries) to terminate the Employee's employment at any time is 
specifically reserved.

      10.  AMENDMENT OF OPTION.  The Option and this Agreement may be amended 
by the Board or the Committee at any time without the consent of Employee (i) 
if the Board or the Committee determines, in its sole discretion, that the 
amendment is necessary or advisable in the light of any addition to or change 
in the Code or in the regulations issued thereunder, or any federal or state 
securities law or other law or regulation, which change occurs after the date 
hereof and by its terms applies to the Option; or (ii) in order to make the 
adjustments set forth in Section 5 hereof.  Other than the matters set forth 
in the preceding sentence, the consent of Employee shall be required in order 
to amend any other provision of this Agreement.  Notwithstanding the 
foregoing, the Committee may, in its sole discretion, accelerate the 
exercisability of the Option at any time.

      11.   NOTICES. Any notice to the Company provided for in this Agreement 
shall be addressed to it in care of its Secretary at the Company's executive 
offices. Any notice to the Employee shall be addressed to Employee at the 
current address shown on the payroll records of the Company.  Any notice 
shall be deemed to be duly given if and when properly addressed and posted by 
registered or certified mail, postage prepaid.

      12.  INCORPORATION OF PLAN BY REFERENCE. The Option is granted pursuant 
to the terms of the Plan, the terms of which are incorporated herein by 
reference, and the Option shall in all respects be interpreted in accordance 
with the Plan.  The Committee shall interpret and construe the Plan and this 

                                       6

Agreement, and its interpretations and determinations shall be conclusive and

hereunder, with respect to any issue arising hereunder or thereunder.  In the 
event any of the terms and conditions set forth in this Agreement are in 
conflict or are inconsistent with the terms of the Plan, the terms of the 
Plan shall control. 

      13.  GOVERNING LAW.  The validity, construction, interpretation and 
effect of this instrument shall exclusively be governed by and determined in 
accordance with the law of the State of Texas.

      14.  CAPITALIZED TERMS.  Unless otherwise defined herein, each 
capitalized term appearing in this Agreement shall have the same meaning as 
the corresponding term in the Plan.    

      15.  BINDING EFFECT.  This Agreement shall be binding upon the parties 
hereto, together with their respective executors, administrators, successors, 
personal representatives, heirs and assigns.

      16.  ENTIRE AGREEMENT.  This Agreement embodies the entire agreement 
and understanding between the parties hereto with respect to the subject 
matter hereof and supersedes all prior agreements and understandings relating 
to the subject matter hereof (including but not limited to those certain 
letter agreements dated December 20, 1994 and September 13, 1996 between 
Antinori Software, Inc. and Employee, which are hereby terminated effective 
as of the date hereof).

      17.  COUNTERPARTS.  This Agreement may be executed in counterparts, 
each of which shall be deemed an original, but all of which together shall 
constitute one instrument.

J.D. CARREKER                                EMPLOYEE CONFIDENTIALITY AGREEMENT

The undersigned employee (the "Employee") of J. D. Carreker and Associates, 
Inc. (the "Company") as a condition of employment or continued employment, 
enters into this Agreement with the Company for the acknowledged purpose of 
protecting the Company against acts by the undersigned or others that would 
adversely affect the best interests of the Company or its customers or the 
ability of the Employee to carry on a satisfying professional relationship 
with J. D. Carreker and Associates, Inc.  To that end, this Agreement 
identifies basic obligations which are binding during the Employee's term of 
employment with the Company and, where applicable, beyond the termination of 
such employment.

BASIC OBLIGATION

The Employee accepts the following obligations:

a.    Employee will perform assigned duties and abide by the published and
      unpublished policies of the Company.
b.    Employee understands and acknowledges that J. D. Carreker and Associates,
      Inc., in its business activities, has developed and uses commercially
      valuable technical and nontechnical information, and to guard the
      legitimate interest of the company, it is necessary for the Company to
      protect certain of the information as confidential.
c.    In consideration of employment or continued employment by Company and as
      a material inducement to the Company to pay Employee compensation for
      services, Employee agrees that confidential information of a special and
      unique nature and value relating to such matters as J. D. Carreker and
      Associates, Inc.'s trade secrets, computer programs, system documentation
      manuals, confidential reports and other proprietary materials is regarded
      by the Company as exceptionally valuable and that its use and disclosure
      must be carefully and continuously controlled.  The Employee agrees to
      deliver all such items in Employee's possession to the Company at any
      time during employment and will do so upon termination of employment.
d.    Employee will never, without Company's prior written consent, disclose to
      or use for the benefit of any person, corporation or other entity, any
      files, trade secrets or other confidential information concerning the
      business, clients, methods, operations, financing, services or any trade
      secret or confidential information of J. D. Carreker and Associates, Inc.

CONFIDENTIAL INFORMATION

Trade secrets and confidential information shall mean all information 
pertaining to the prior, 

<PAGE>

current, or contracted business of the Company or any other information not 
known to the general public.
