result of this License and Xchange shall not acquire any rights, express or
implied, to such derivative work. Carreker may, pursuant to the License,

Section 4.3 below.

      4.3   Carreker shall indemnify, defend and hold harmless Xchange
(including Xchange's partners, officers, directors, employees, agents and
affiliates) from and against any and all expenses (including but not limited

judgments and settlements arising out of or related to any third party claim
or action which arises out of or relates in any way to, in whole or in part:
(i) any addition to or modification of EnAct by Carreker; (ii) the use by
Carreker or its customers and/or licensees of a superseded or altered release

current or unaltered release of EnAct; (iii) the combination, operation or use
by Carreker or its customers and/or licensees of any component of EnAct
furnished under this Agreement with software, hardware or other materials not

      4.4   The rights of either Party (the "Indemnified Party") to the
indemnification from the other Party (the "Indemnifying Party") set forth in
Sections 4.1, 4.2 or 4.3 above are subject to the Indemnifying Party receiving
from the Indemnified Party (a) prompt written notice of any such claim (but
failure to give such prompt notice shall only be a disqualification to
indemnification to the extent that such failure results in material and
permanent prejudice to the defense of the claim), and (b) all reasonable
requested assistance, in the defense or settlement of such claim or suit. The
Indemnifying Party shall provide reimbursement for out of pocket expenses
incurred by the Indemnified Party in providing requested assistance hereunder.
The Indemnifying Party shall be given the full and complete authority and

Party must completely release the Indemnified Party from all liability related
to the claim. In no event shall the Indemnifying Party be responsible for the
settlement of any claim entered into by the Indemnified Party unless such
Indemnifying Party (x) was given full notice of the terms and conditions of the
settlement and (y) has expressed its approval to such settlement in writing.

      4.5   The Parties' respective rights and remedies for the matters
described in this Section 4 shall be limited to the indemnification set forth
in this Section 4. If any action or claim

<Page>

                                     -6-

of the type described in Section 4.2 or 4.3 is commenced or threatened or, in
the opinion either Party, is likely to be commenced or threatened, the Party
that bears, or would bear, the obligation to provide indemnification pursuant
to section 4.2 and 4.3 with respect to such action or claim shall take
commercially reasonable efforts to provide and/or procure (but, except for the
indemnification provided in Section 4.2 and 4.3, shall not have any liability
to the other Party for any failure to so provide and/or procure) a license,
right, modification, replacement or other solution to allow the continued use
or other exploitation of the intellectual property in question or to otherwise
settle, avoid or resolve the claim or action in question. Notwithstanding the
foregoing, in the event that an injunction is issued which prevents the use of
the intellectual property in question and neither Party is able, after
commercially reasonable efforts, to produce a modification or replacement for
the infringing intellectual property, the indemnifying Party agrees to use
commercially reasonable efforts to obtain, or assist the other Party to
obtain, a license on commercially reasonable terms for the infringing
intellectual property.

WARRANTY OF ANY KIND. XCHANGE HEREBY DISCLAIMS ALL WARRANTIES, WHETHER EXPRESS

ACKNOWLEDGES THAT EXCEPT AS EXPRESSLY PROVIDED HEREIN NO OTHER WARRANTIES WITH
RESPECT TO THE SUBJECT MATTER OF THIS AGREEMENT HAVE BEEN MADE TO CARREKER BY
OR ON BEHALF OF XCHANGE OR OTHERWISE FORM THE BASIS FOR THE BARGAIN BETWEEN
THE PARTIES.

      5.4   IN NO EVENT SHALL EITHER PARTY BE LIABLE TO THE OTHER PARTY FOR
SPECIAL, PUNITIVE, EXEMPLARY, INDIRECT, INCIDENTAL, CONSEQUENTIAL, TORT OR OTHER
DAMAGES (EXCEPT DIRECT DAMAGES), INCLUDING WITHOUT LIMITATION ANY DAMAGES
RESULTING FROM LOSS OF USE, LOSS OF DATA, LOSS OF PROFITS, CLAIMS BY THIRD
PARTIES OR LOSS OF BUSINESS ARISING OUT OF, IN CONNECTION WITH OR IN ANY WAY

relationship of employer and employee, independent contractor or principal and
agent between Xchange and Carreker and under no circumstances shall Carreker
be considered an employee or agent of Xchange. Neither Party shall have the
authority to vary, alter or enlarge any of the other Party's obligations
hereunder or to make representations, warranties or guarantees on behalf of
such other Party.

      6.5   No waiver of any default hereunder shall operate as a waiver of any
other default or of a similar default on a future occasion. No waiver of any
term or condition hereof shall be effective unless the same shall be in writing
and signed by an authorized representative of the Party waiving such term or
condition. No remedy referred to in this Agreement is intended to be exclusive,
but each shall be cumulative and in addition to any other remedy referred to
herein or otherwise available at law or in equity.

      6.6   Neither Xchange nor Carreker shall be liable for any delays in their
performance of any obligations hereunder due to causes beyond its reasonable
control, including, but not limited to, fire, strike, war, riots, acts of any
civil or military authority, acts of God, unavailability or shortages of
materials or equipment, failures or delays in delivery of vendors and suppliers
or delays in transportation.

      6.7   Each Party hereto agrees that it will not make any public disclosure
of the specific financial terms of this Agreement without the prior written
consent of the other Party hereto and neither Party shall use the other Party's
name in any marketing, promotional or other materials without the express prior
written consent of such other Party, which consent shall not be unreasonably
withheld. Notwithstanding the foregoing provisions of this Section 6.7, consent
shall not be required in any event if such disclosure is required by applicable
law, rule or regulation; provided, however, that with respect to any press
release required by any rules or regulations of the Securities and Exchange
Commission, the disclosing Party shall provide the other Party with a copy of
such release within a reasonable time prior to such disclosure.

with, the substantive law of the State of Delaware, without giving effect to
choice of law principles. The United Nations Convention on Contracts for the
International Sale of Goods shall not apply to any of the transactions
contemplated by this agreement.

      6.9   The Parties agree that this Agreement is entered into in connection
with the compromise, resolution and settlement of the legal proceeding
referenced in Section 1.3 above and that such compromise, resolution and
settlement shall not be taken as an admission of liability by any Party, but
rather, such liability is expressly denied; nor shall this Agreement be
admissible in any proceeding or cause of action as an admission of liability
against the Parties.
