out-of-pocket expenses incurred, including travel to and from Customer's sites,
lodging, meals and shipping, as may be necessary in connection with duties
performed under this Section 4 by VeriSign.

     4.3  MAINTENANCE PROVIDED BY VERISIGN. For periods for which Customer has
          --------------------------------                                    
paid an annual maintenance fee, VeriSign will provide Customer with the
following services:

          4.3.1  TELEPHONE SUPPORT. VeriSign will provide telephone support to
                 -----------------

the Licensed Software which causes the Licensed Software not to operate in
material conformance to VeriSign's published specifications therefor, Customer
shall submit to VeriSign a written report describing such error in sufficient
detail to permit VeriSign to reproduce such error. Upon receipt of any such
written report, VeriSign will use its reasonable business judgment to classify a
reported error as either: (i) a "Level 1 Severity" error, meaning an error that
causes the Licensed Software to fail to operate in a material manner or to
produce materially incorrect results and for which there is no workaround or
only a difficult workaround; or (ii) a "Level 2 Severity" error, meaning an
error that produces a situation in which the Licensed Software is usable but
does not function in the most convenient or expeditious manner, and the use or
value of the Licensed Software suffers no material impact. VeriSign will
acknowledge receipt of a conforming error report within two (2) business days
and (A) will use its continuing best efforts to provide a correction for any
Level 1 Severity error to Customer as early as practicable; and (B) will use its
reasonable efforts to include a correction for any Level 2 Severity error in the
next release of the VeriSign Software. In the event that VeriSign fails to
comply with the Service Level Agreement attached as Exhibit B to this Exhibit J,
and VeriSign is unable to cure the problem within a reasonable period specified
in Exhibit B, Customer shall have the right to obtain release of the source code
for the Licensed Software from escrow. Customer's rights to the source code
released from escrow shall be limited to use for the purpose of Customer's
operation of the Private Label Certificate System, and Customer may not resell,
sublicense or otherwise permit the use of such source code by any third party
unless VeriSign gives prior written authorization on mutually agreeable terms
and conditions.

additional charge. New Versions will be provided at VeriSign's standard upgrade
charges in effect at the time. Any New Releases or New Versions acquired by
Customer shall be governed by all of the terms and provisions of this Agreement.

     4.4  LAPSED MAINTENANCE. In the event Customer has not purchased optional

of a New Release of such Licensed Software or any service which is provided as a
part of maintenance by paying the maintenance fees which would otherwise have
been due from the expiration of maintenance provided pursuant to Section 4.1 to
the date such New Release is licensed or such service is provided.

     4.5  DEVELOPMENT. If Customer requests that VeriSign make modifications or
          -----------

                                    OVERVIEW
                                        
This Service Level Agreement (SLA) between Visa International (Visa) and
VeriSign, Inc. (VeriSign) details the terms for the supply of services by
VeriSign to Visa for the operation of the Visa Chip Card Certification Service
(CCCA). It specifically addresses the service levels that will be in effect for
the pilot phases of the CCPS and SVC Diamond projects. Additional service levels
may be implemented after the commencement of either of these two pilots.

This SLA is comprised of two components. The first addresses service levels for
CCCA. The second addresses service levels for VeriSign CCCA customer support.

CCCA SYSTEM DESCRIPTION

A logical depiction of the CCCA system is presented below:

             [DRAWING OF TWO RECTANGLES LABLED "ISSUER" AND "VISA"
                       WITH CONNECTING HORIZONTAL BARS]      
<PAGE>

     
SCOPE

VeriSign will be developing and operating a Certificate Authority on behalf of
Visa

WITHIN SCOPE
The following components of CCCA are addressed within the scope of this service
level agreement:

     Brand Certificate Authority (Brand CA)
               Acceptance of Issuer Public Key from Visa
               Generation of Issuer Public Key Certificates
               Reconveyance of Issuer Public Key Certificate to Visa

OUTSIDE OF SCOPE
The following components of CCCA are not addressed within the scope of this
service level agreement:

     Visa system infrastructure
     Deployment of Visa Scheme Public Keys
     Issuer to Visa key management processes
     Establishment of trust between Issuers and Visa
     Conveying of Issuer Public Key Certificate to Issuer

DEFINITION

     Brand Certificate Authority

     The Brand CA issues EMV compliant Issuer Public Key Certificates to Brand
     members (i.e., Issuers) that wish to use the Visa Chip Card Payment Systems
     (CCPS) and/or Stored Value Card (SVC) products.

     For CCPS the Brand CA generates Issuer Public Key Certificates to enable
     Issuers to utilize Static Data Authentication for their customer needs.

     For SVC the Brand CA generates Issuer Public Key Certificates to enable
     Issuers to utilize Dynamic Data Authentication for their customer needs.

CCCA SERVICE LEVELS

For the purpose of this SLA, CCCA is considered to have one major operational
component:

1.   Certification Processing Service

     This is the ability to process the certificate transaction (i.e.,
     certificate request, certificate generation, certificate response) and
     return an appropriate signed response to the requester.      
<PAGE>

     
SERVICE AVAILABILITY

Definition

     Initially, for the pilot phases of the projects covered by this SLA, the
     Brand Certificate Authority (Brand CA) operations require manual
     procedures. These are performed off-line and need the presence of
     authorized Visa and VeriSign personnel. To maintain multiple controls over
     the use of the Visa Brand Private Keys, three (3) of five (5) key
     custodians must be present to enable the generation of any Issuer Public
     Key Certificate. At least one designated key custodian must be present from
     Visa and at least one designated key custodian must be present from
     VeriSign to perform this service, i.e., the three key custodians must not
     all be representatives from one organization. The designation of the key
     custodians from each organization is not a part of this SLA, but all key
     custodians must be approved by Visa.

     The Brand certificate authority must be available during the normal hours
     of operation, as well as after hours by prior arrangement.

     Normal hours of operation for the Brand CA are 0800 - 1700 PT, 5 days a
     week, 52 weeks a year. Visa will normally provide VeriSign with one working
     day advance notice of any required Brand CA operation.

     In the event of extreme conditions, such as disaster recovery or key
     compromise, Visa may require Brand CA operations outside of the normal
     operating periods. Under such circumstances, Visa shall provide VeriSign
     with a two (2) day advance notice of the required Brand CA operations.

Measurement

     The measurement for service availability is the amount of time that the CA
     is capable of receiving, processing and responding to incoming certificate
     transactions from the requesting entity (i.e., the Issuer through Visa).
     Nonavailability is the amount of time that the CA is not capable of
     receiving, processing and responding to incoming certificate transactions
     from the requesting entity.

Minimum Service Level Requirement

     The Brand CA must be available to process 99% of the certificate requests
     and perform necessary administrative functions.

RESPONSE TIME

Definition
There are two components of response time for the Brand CA.      

                                      -2-
<PAGE>

     
     1.   The amount of time that it takes VeriSign to respond to a Visa request
          for Brand CA operations.

          VeriSign must respond to a Visa request for Brand CA operations within
          one working day during normal operating hours. Under extreme
          conditions, VeriSign must respond to a Visa request for Brand CA
          operations within one (1) hour during normal operating hours.

     2.   The amount of time that the actual Brand CA operation requires.  All
          Brand CA operations must be processed and validated within 8 hours of
          the start of the operation. If the validation process is extended by
          factors out of VeriSign's control, VeriSign will not be penalized.

Measurement

     The measurement for response to requests for Brand CA operations is based
     upon the time elapsed from when Visa contacts VeriSign to inform them of
     the intent to perform a Brand CA operation until VeriSign confirms their
     availability to perform a Brand CA operation.

     The measurement for performing Brand CA operations is based upon the time
     elapsed from when Visa staff arrives at VeriSign to begin the operation
     until the operation is completed and verified.

Minimum Service Level Requirement

     For the Brand CA, 99% of the requests for Brand CA operations must be
     responded to within the required time and 99% of the Brand CA operations
     must be performed within the required time.

DATA MANAGEMENT

Definition


     CCCA data, which includes system logs, transaction history, certificate
     registration data and certificates, must be available to support various
     legal, billing and customer service requirements. The archive retention and
     retrieval requirements for the CCCA data will vary by data type as
     described below:

          Registration data and certificates

          This data will be kept available for immediate review for 90 days
          prior to being archived. Archived data will be maintained for the
          length of the one year pilot and must be retrievable within 24 hours
          of request. At the end of the pilot project, all archived data will be
          returned to VISA.      

                                      -3-
<PAGE>
     
          System logs and transaction history

          This data will be kept available for immediate review for 90 days
          prior to being archived. Archived data will be maintained for the
          length of the one year pilot and must be retrievable within 24 hours
          of request. At the end of the pilot project, all archived data will be
          returned to VISA.

Measurement

     The measurement for data management is based upon the data being available,
     within the periods specified above.

Minimum Service Level Requirement

     The data management requirements must be met 99% of the time.

SYSTEM MONITORING AND OUTAGE REPORTING

Definition

     Monitoring

     The key storage units for all of the CAs must be checked for tampering on a
     daily basis. The applications and/or systems for the Certification
     Processing Service must be monitored continually and a status check taken
     every 24 hours.

     Outage Reporting


     All CCCA hardware and/or software faults shall be logged, tracked and
     reported using a suitable computer-based system and provided to Visa within
     two (2) hours of occurrence.

     All CCCA system hardware, network, and software failures, their impact on
     CCCA operations and any actions taken to correct the problem, including an
     event log shall be reported to Visa on a monthly basis. In addition, Visa
     shall be notified within one hour of any major failure that affects the
     normal operation of CCCA.

Measurement

     The status checks must be recorded on a status log and signed by the
     VeriSign system operator. This status log must be available for review by
     Visa at any time.

     Problem / event logs and system logs will record outages and causes (if
     known). These also must be made available to Visa for review at any time.
     
                                      -4-
<PAGE>
     
Minimum Service Level Requirement

     Compliance with the monitoring, logging and reporting requirements must be
     99%.

SCHEDULED DOWN TIME

Definition

     There will be a scheduled down time period weekly to perform maintenance,
     backup and upgrade functions for the CAs. This period will not exceed 12
     hours and will be at the same time each week as agreed to by Visa and
     VeriSign. If a longer down time window is needed, it must be agreed to in
     advance by Visa and VeriSign.

Measurement

     The measurement for scheduled down time for any CA is based on the time
     elapsed from when the CA is not capable of performing operations until it
     becomes available for performing operations. Daily system logs will
     indicate scheduled system down time and can be used to track outages.

Minimum Service Level Requirement

     99% of the down times must be within the required period.

BACKUP

Definition

     At a minimum, all data related to the Brand CAs, including application
     files and databases, system tables, log files, etc., will be backed up on a
     scheduled, daily basis. In addition, the Brand CA application and all
     system components will be backed up on a monthly basis. All backups must be
     done non disruptively without adversely impacting normal CCCA operations.
     The backup files must be stored in a secure off-site facility as agreed
     upon by VeriSign and Visa.

Measurement

     Daily system logs will indicate time and location of backup files, backup
     media identification and any other relevant information needed for recovery
     of backup files.

Minimum Service level Requirement

     The backup requirements must be met 99% of the time.
     
                                      -5-
<PAGE>
     
KEY COMPROMISE

     The management of key compromise, CRL processing, replacement of Visa
     Scheme keys and the re-generation of Issuer Public Key Certificates will
     not be a provided service for the pilot phases of CCCA.

CONTINGENCY OPERATIONS/RECOVERY

Definition

     If any single component of the Brand CA fails, the component shall be
     recovered to the point of failure within five (5) calendar days.

     In the event of a total Brand CA failure, a complete recovery must occur
     within five (5) calendar days and normal operations should begin with
     recovery to the point of failure for all systems and files. In the interim
     period before normal operations have begun, Access to Service must be
     available to receive certificate transactions, queue the transactions for
     future processing and provide an appropriate signed response to the
     requesting entity.

Measurement

     The measurement for recovery of an CCCA system component or a total system
     outage will the length of time between the point that the outage occurs and
     the point that a full recovery to normal operations has been completed.

     The ability to satisfy the recovery and/or contingency operations
     requirements will be demonstrated through periodic scheduled tests.

Minimum Service Level Requirement

     The recovery and contingency operations requirements must be met 99% of the
     time.

REPORTING

     VeriSign shall provide Visa with reporting on a scheduled basis. This will
     include both service level and activity reporting and may be either on hard
     copy or electronic (i.e., report or data files) form as agreed to by Visa
     and VeriSign.

PENALTIES

     All service levels are calculated, and penalties assessed, on a monthly
     basis.
     
                                      -6-
<PAGE>
     
VERISIGN CCCA CUSTOMER SUPPORT SERVICE LEVELS

     VeriSign will provide support to Visa as described in the customer support
     requirements section of the contract. The VeriSign interface for customer
     support will be limited to designated individuals within Visa.

AVAILABLITY

     VeriSign Customer Service must be available to accept and respond to
     problem calls from Visa 0800 - 1700 PT, 5 days a week, 52 weeks a year,
     (i.e., a standard financial Industry schedule).

RESPONSE TIME

     Normal Hours of Operation

     Between 0800 and 1700 PT, a human VeriSign Customer Support representative
     should respond immediately (i.e., answer the telephone within a queue time
     of 120 seconds).

CUSTOMER SUPPORT CALLBACK TIMEFRAMES AND DEFINITIONS

     VeriSign Customer Support will, at a minimum, initiate a return telephone
     call to Visa to establish if the problem has been corrected based on the
     following call reporting criteria:



     Problem Severity                      Definition                     Callback Frequency
     -------------------------------------------------------------------------------------------
                                                                    
     1                                     Entire population of a CA      60 minutes
                                           impacted
     -------------------------------------------------------------------------------------------
     -------------------------------------------------------------------------------------------


     In every case, if the problem has not been corrected within the callback
     frequency, VeriSign Customer Support will monitor the problem to determine
     if any corrective work has begun. If it has, then VeriSign Customer Support
     will continue to monitor the situation and provide status to Visa until the
     problem is resolved to the satisfaction of Visa. If not corrective work has
     begun, VeriSign Customer Support will escalate the problem to the next
     support level.

     SUPPORT LEVELS

     1.   SECOND-LEVEL SUPPORT FOR MEMBERS

     VeriSign will provide second level telephone support for any problem
concerning a Certificate issued to a Member during the times set forth in
Section 2 below. In the event that a Member problem is not resolved by the first
level good-faith efforts of VISA Member Support, VeriSign will provide second
level telephone support for a reasonable volume of calls from VISA Member
Support. Upon VISA Member Support's providing VeriSign with a clear description
of the unresolved problem, VeriSign will verify the problem's existence and
determine the conditions under which the problem may recur. After such
verification and determination, VeriSign will, at its option,

          1.1   use its best efforts to provide an immediate fix for the
problem;

          1.2   use its best efforts to provide a temporary solution of or
workaround to the problem;

          1.3   provide a statement that the problem will be corrected in a
future release;

          1.4   provide a statement that more information about the problem is
required (however, after sufficient information, in VeriSign's opinion, is
provided to VeriSign, VeriSign will provide to Customer one of the other four
support alternatives contained in this Section 1); or

          1.5   provide a statement that the Private Label Certificate System
operates as described in VeriSign's then current user documentation or that the
problem arises when such Private Label Certificate System is used other than in
a manner for which it was designed.

     In the case of such second-level support, VeriSign will not contact a
Member directly for more information about the problem unless VISA Member
Support so requests.
