 Agreement").

 B.   The Parties jointly wish to make additions to the Original Agreement.

 C.   The additions to the Original Agreement are set forth in this Addendum.

                                  AGREEMENT:

                                                                   EXHIBIT 10.17

                              AGREEMENT AND RELEASE

     This is an Agreement and Release, dated the 2nd day of November, 2001 (the
"Agreement"), made by and between Pegasystems Inc., a Massachusetts corporation
("Pega"), and Carreker Corporation, formerly Carreker-Antinori, Inc., a Delaware
corporation ("Carreker") (Pega and Carreker may be individually referred to as a
"Party" and collectively referred to as the "Parties").

     WHEREAS, Pega filed suit against Carreker, which action is currently
pending in the Court of Chancery of the State of Delaware in and for New Castle
County under Civil Action Number 19043 (the "Litigation"), alleging various
causes of action relating to and arising from disputes concerning a Product
Development, Distribution and Sublicensing Agreement dated May 5, 1999 and
modified on June 27, 2000 and October 31, 2000 (the "Product Development
Agreement"); and

     WHEREAS, Pega and Carreker seek to terminate the Product Development
Agreement; and

     WHEREAS, Carreker initiated an arbitration before the American Arbitration
Association in Dallas, Texas of disputes arising under the Product Development
Agreement (the "Arbitration") (the Litigation and the Arbitration are
collectively referred to as the "Legal Proceedings"); and

     WHEREAS, the claims and defenses, both legal and factual, advanced by
Carreker and Pega in the Legal Proceedings are disputed. Nevertheless, the
Parties wish to compromise and settle all matters raised by the Legal
Proceedings between Carreker and Pega, for the sole purpose of avoiding the
uncertainty and expense of the Legal Proceedings and,

     WHEREAS, both Parties desire to bring the Legal Proceedings to an end and
to resolve all issues and monetary disputes;

     NOW THEREFORE, in consideration of the premises, the mutual covenants and
obligations set forth in this Agreement and other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
Parties hereto agree as follows:

                            I. SUPERSEDED AGREEMENT

     The Product Development Agreement is terminated on the Effective Date of
this Agreement by both Parties.

     This Agreement shall supersede all prior agreements between the Parties
relating to the subject matter hereof.

                                II. DEFINITIONS

When used in this Agreement the capitalized terms listed in this section have
the following meanings:

"Carreker" means Carreker Corporation and any majority-owned affiliates or
subsidiaries of Carreker Corporation including but not limited to Carreker Check
Solutions LLC.

"Effective Date" means the execution date of this Agreement.

"Pega" means Pegasystems Inc. and any majority-owned affiliates or subsidiaries

"CheckFlow Product" is some or all combinations of the following: automated
check research (Check All Items), photo retrieval (Check Retrieval) and
adjustments solution (Adjust), together with a flexible workflow engine.

"Adjustments/Express" is a check adjustment product for banks. As errors are
found during the check capture and posting processes, offsetting adjustments are
created to both internal departments and downstream banks. Advice notices are
also received from sending banks that have found errors in their capture and
posting process. Adjustments/Express serves as a warehouse of these pending
adjustment items and presents operators with the necessary information to
resolve the adjustments and settle with the downstream or upstream banks,
including the retrieval of check images requested by the operators who are
assigned to resolve the adjustment item. The system makes the appropriate
internal accounting entries and creates the appropriate correspondence to the
banks and internal departments.

"All Transaction File (ATF)" is a database product that provides the banks'
installed applications with information needed to assist in the resolution of
adjustments, answer customer inquiries, and reconstruct lost or missing cash
letters/bundles. In addition, ATF can provide information to other applications
such as fraud, kiting or inbound returns. This database is created by interfaces
from the check capture and the DDA (Demand Deposit Accounting) posting systems.

"Inbound Returns/Express" is an inbound return items product for banks. As
inbound return items are received from other banks, the bank of first deposit
(receiving bank) has the job of deciding the final disposition of that item and
the proper manner of either charging back the item to the customer's account or
re-presenting the item. The system keeps track of the inbound cash letters,
gives the operator the customer specific information on how to handle the item,
and creates files for downstream processing of the physical items. Inbound
Returns/Express can retrieve check images to aid in the inbound return item
processing function.

"Exceptions/Express" is an outbound return items product for banks. Charged with
the task of deciding if an item should be paid or returned to the bank of first
deposit, operators in the returns department are presented with the necessary
data (including the retrieval of check images) on their workstation to process
these returns in a timely and informed manner. The system also creates files for
downstream processing to allow the return of the physical document when
necessary.

                      III. ASSIGNMENT OF CHECKFLOW PRODUCT

1. Except as necessary for Carreker to fulfill its obligations to KeyBank and US
Bank, Carreker hereby assigns to Pega all rights, title and interest it may have
in the CheckFlow Product jointly developed under the Product Development
Agreement. Pega is free to market any and all Pega products or the CheckFlow
Product without obligation to Carreker. Both Parties shall exercise reasonable
best efforts to return all confidential information provided by the other Party
including any intellectual property and any books, papers or records with
respect to such CheckFlow Product, except for information needed solely for
fulfilling such Party's obligations under this Agreement or as necessary for
Carreker to fulfill its obligations to KeyBank and US Bank.

                                  IV. PAYMENT

2. In consideration of the following payments outlined herein in Paragraph 2 and
Paragraph 3, Pega grants to Carreker a fully paid, non-exclusive, perpetual
development license to the CheckFlow Product with no rights to sublicense such
CheckFlow Product. This license is provided AS IS with no warranty, maintenance
or service obligations from Pega. Carreker shall cause to be paid to Pega the
total sum of THREE MILLION EIGHT HUNDRED AND FIFTY THOUSAND DOLLARS
($3,850,000.00) by wire transfer to the account number of Pegasystems Inc.,
which shall be provided to Carreker. Such payments shall be made in four
quarterly installments consisting of $900,000.00 due within three business days
of the Effective Date of this Agreement; $900,000.00 due on or before February
28, 2002; $900,000.00 due on or before May 31, 2002 and $1,150,000.00 due on or
before August 31, 2002.

3. In addition to the foregoing, Carreker shall cause to be paid to Pega the sum
of THREE HUNDRED SIXTY FIVE THOUSAND NINE HUNDRED AND TWENTY SIX DOLLARS
($365,926.00) in consideration of all outstanding Pega invoices. Such payment
shall be delivered to Pega by wire transfer within three business days of the
Effective Date of this Agreement to the account number of Pegasystems Inc.,
which shall be provided to Carreker.

The above payments shall be in full satisfaction of all the monies Carreker owes
or shall be obligated to pay Pega related to claims against Carreker in
connection with the Legal Proceedings or the Product Development Agreement,
other than the royalty payments specifically set forth below.

                          V. RIGHT TO MARKET PRODUCTS

4. Except for the royalty obligations set forth below for Adjustments/Express,
All Transaction File, Inbound Returns/Express and Exceptions/Express, Carreker
is free to market all of its products without obligation to Pega.

                                  VI. ROYALTY

5. Carreker shall pay Pega a royalty based upon the percentage of the license
and maintenance fees, net of existing third party royalty obligations as of the
Effective Date of this Agreement as listed in Schedule A attached hereto, that
Carreker collects from customers who license Adjustments/Express, All
Transaction File, Exceptions/Express and Inbound Returns/Express, or any new
releases or versions of such products or successor products, with royalty
percentages as set forth in the following table. Successor products are any
products introduced by Carreker subsequent to the date of this Agreement that
are designed or otherwise intended to replace material functionality imbedded in
the products subject to royalty obligations such that the successor product
effectively eliminates or significantly reduces the market demand for those
products subject to royalty obligations. Carreker agrees that any licenses of
the above listed products are to be licensed at fair prices that will not
transfer value between elements of a multi-element agreement with a customer and
will not transfer value between the various products described herein so as to
avoid paying royalties to Pega. For purposes of the above sentence, any pricing
concessions Carreker is required to provide a customer in satisfaction of
product or performance issues directly related to any product license that is
not subject

                                       Page 3 of 14

<PAGE>

to Pega royalty obligations and for any concessions made to customers for claims
related to the Legal Proceedings shall be considered a separate "element" of the
contract in which such pricing concessions are made (i.e. - the value of the
concession shall be added back to the contract value when computing royalty
obligations due to Pega).

business hours, all of Carreker's books and records which may reasonably pertain
to Carreker's royalty obligations under this Agreement at Carreker's place of
business as set forth in the notice paragraph to this Agreement or as otherwise
designated by Carreker. In years 2-5 the audit frequency will be reduced to once

Pega's request. Any such audit shall be limited to no more than the immediately
preceding 24 month period and shall not include any periods previously audited.
