                         infringement of any third party's patent, copyright,
                         trademark, trade name, other proprietary right, or
                         unauthorized trade secret use. ClearCommerce agrees to
                         pay all damages and costs awarded with respect to such
                         claim or agreed to in any settlement of that claim.

                8.5.2.   In case any Program or Documentation or any part
                         thereof in such suit is held to constitute an
                         infringement and its use is enjoined, ClearCommerce
                         will, at its own expense and at its option (i) procure
                         for HP and its customers the right to continue use, or
                         (ii) if applicable, replace the same with, a
                         noninfringing program and documentation of equivalent
                         function and performance, or (iii) modify them so they
                         become noninfringing without detracting from function
                         or performance.

                8.5.3.   HP will give ClearCommerce prompt notice of any such
                         claim or action, and will give ClearCommerce the
                         authority, information, and reasonable assistance (at
                         ClearCommerce's expense) necessary to defend. If
                         ClearCommerce does not diligently pursue resolution of
                         the claim nor provide HP with reasonable assurances
                         that it will diligently pursue resolution, then HP may,
                         without in any way limiting its other rights and
                         remedies, defend the claim.

                8.5.4.   Notwithstanding the foregoing, ClearCommerce will have
                         no responsibility for claims arising solely and
                         directly from (i) unauthorized modifications of the
                         Program made by HP if such claim would not have arisen
                         but for such modifications, or (ii) unauthorized
                         combination or use of the Program with products not
                         contemplated herein if such claim would not have arisen
                         but for such combination or use.

* "Initial Response Time" is the time for a return call from ClearCommerce to HP
to acknowledge the error and to estimate the time for delivery of the
resolution.

5. Escalation of Customer Problems
a) Initiating Escalation. The escalation procedure ("Escalation") will be
followed if either party believes a Customer situation requires additional
attention by the other party to resolve the problem. Either party will initiate
Escalation if the normal avenues for problem resolution have been exhausted.
Conditions which will trigger Escalation include high levels of Customer
anxiety, disagreement between the parties as to responsibility for pre-screened
problems, Clearcommerce's failure to meet the response time under Section 4(l)
above, HP's failure to adequately co-operate with ClearCommerce, or recurring
intermittent critical Problems which remain unresolved after two (2) attempts.

                                       25
<PAGE>

b) Escalation Process. Either party's Strategic Contact will call the other
party's Strategic Contact to request Escalation. Once a party requests
Escalation, appropriate contacts are designated within each party's
organization. The individual designated as the escalating party's Problem Site
Manager will then contact the other party's Problem Site Manager to develop and
write an Action Plan, as defined below. This Action Plan will outline the
specific steps the parties, both individually and mutually, will take. The
Action Plan is then followed and updated as necessary. When the problem has been
resolved, or it is determined that a resolution is not possible, the monitor
phase is initiated. When monitoring indicates that the problem is resolved, the
Escalation is closed.

If Escalation is consistently requested by either party for a number of
Customers over a period of time, then either party may request in writing that
the Support Operations be reviewed by and discussed between the appropriate HP
and ClearCommerce Vice Presidents. The Vice Presidents shall develop an
appropriate Action Plan to resolve the situation. The effectiveness of the
Action Plan will be reviewed after three (3) months. Agreed upon changes shall
then be made to the Support Operations.

c) Designated Contacts. Once Escalation has been requested, each party will
designate individuals with the responsibilities listed below and will promptly
report these designates and their telephone numbers to the other party's
Operational Contact. An individual may fulfil multiple roles, provided he/she
can carry out the described responsibilities. Once designated, the individuals
will establish and maintain direct contact with their counterparts until the
escalation is closed as described below.

         i.    Problem Site Manager. The Problem Site Manager ensures the Action
               Plan is developed, written, and communicated properly, provides
               the highest level of technical knowledge short of factory/lab;
               provides on-site assistance as appropriate; and ensures problem
               replication and generation of technical "work-around," if
               possible.

         ii.   Factory Problem Manager (designated whenever needed; does not
               have to be designated initially). The Factory Problem Manager
               manages Escalation communications within factories/labs involved;
               utilizes factory/lab resources for escalated problem support;
               analyses problem data sent from field; reviews action plan; and
               ensures prompt factory/lab response to escalated field requests

         iii.  Strategic Contacts. If at any time during Escalation, one party
               feels the problem is not being dealt with or the other party is
               not responding adequately to requests for assistance, the
               respective Strategic Contact will be notified. The Strategic
               Contacts will then work together to resolve the issue.

d) Action Plan. The designated contacts will work together to develop a mutual
Action Plan as quickly as possible which establishes, at minimum:

               *  Actions to be taken, which may include (i) reprioritizing
                  commitments, (ii) increasing resources, (iii) establishing
                  remote dial into Customer system for direct observation, or
                  (iv) sending engineers on-site.
               *  Responsibility for each action
               *  Purpose or desired result of each action
               *  Expected completion of each action
               *  Contingency/next step if desired results are not achieved

                                       26
<PAGE>

               This Action Plan will be modified by mutual agreement among the
               designated contacts whenever the situation requires.

e) On-Site Visits. During Escalation, either party may request that the other
party send engineers on-site to resolve escalated problems. Typical situations
for which a party may request on-site Visits may include: (i) when the Customer
perceives that its business relationship is deteriorating due to persistent
problems with the ClearCommerce Programs, or (ii) when it is not possible or is
extremely inconvenient to reproduce the problem remotely, at the ClearCommerce
site, or at HP in a timely fashion.

f) Status Updates. Each designated contact will establish a schedule of follow-
up, status update communications with his/her counterpart that will ensure
timely exchange of information.

g) Monitor Phase. The purpose of the monitor phase is to evaluate the Customers
environment over some period of time to verify that the problem has been
resolved. Both parties will co-ordinate monitoring activities and mutually agree
to close the monitor phase when it is clear the problem is resolved.

h) Closing Escalation. When both parties agree that the problem has been
resolved or the situation no longer requires Escalation, the Escalation is
closed. Each designated contact will exchange final reports with his/her
counterpart summarizing the Customer problem(s), actions taken, results of those
actions, likelihood of problem recurrence, and recommended future actions.

6. Relationship Management
a) Strategic Contacts. ClearCommerce and HP will each designate an employee who
shall serve as the sole liaisons between HP and ClearCommerce as each party's
strategic contact for support related matters ("Strategic Contact"). Each party
shall notify the other whenever the designated Strategic Contacts'
responsibilities are transferred to another employee. The Strategic Contacts
will be the focal points for general relationship and process issues and will be
responsible for managing the overall support relationship of the parties. The
initial Contacts are set forth below.

b) Cooperation. HP and ClearCommerce acknowledge that the timely provision of
and access to assistance, co-operation, complete and accurate information and
data from their officers, agents, and employees are essential to performance of
any technical support services, and that each party's ability to provide such
services is dependent upon same
