(i.e. the new digital intermediary), and future models of electronic commerce by
providing an object-oriented, extensible framework on which this application and
future applications can be built and deployed. Not only does the Beehive
architecture support new and evolving models of eCommerce, but it also supports
existing models such as the Mall and Single Supplier/Store. A standardized
framework provides consistent practices regarding customization, which enable
quicker implementation and customization for Intershop's customers and
Intershop's professional services group. Beehive and products that run on the
Beehive platform and applications that incorporate the PowerTier runtime are
expected to be Intershop's a primary revenue stream in 1999 and Intershop's

NOTE 2: Attached to this Agreement as Exhibit C is a document describing the

Once these enhancements have been delivered, Intershop will be invoiced for Item
7 above.

NOTE 3: Royalties at the rate specified in Item 8 above shall be charged on all
Intershop net revenues (net of any sales tax) generated by products containing

of any sales tax) generated by products containing the PowerTier Object Builder
subject to the limitations defined in Note 5 of this Cover Sheet. For purposes
of this Note 3, "net revenue" means gross revenues, less any applicable sales,
use, or withholding taxes, or any applicable ad valorem taxes.

Developer Pack to work related to the End-User's use of Beehive.

NOTE 6: Intershop agrees that any use of GUT will be entirely at their own risk
and will be unsupported. Intershop will be responsible for the maintenance of
any code generated by GUT, and support for any PowerTier generated code that
contains GUT-generated code will only be provided if the problem can be
reproduced with the GUT-generated code removed. Intershop also agrees that GUT
and any documentation relating to GUT is entirely confidential and therefore
specifically and especially covered by clauses 2.1.3, 3 and 10. Under no
circumstances may GUT be used by anyone other than Intershop employees, and
under no circumstances may GUT be used other than at Intershop premises. PSI
will give good faith consideration to allowing Intershop to sublicense GUT to
Intershop's customers.

the beginning of the next year of this Agreement, then PSI may elect to withhold
from Intershop such Support Services. The withholding of Support Services by PSI
does not release Intershop from any obligations arising from this Agreement nor

PowerTier/EJB Product Commitments for Intershop
-----------------------------------------------

Persistence undertakes to enhance its PowerTier/EJB product for Intershop as
detailed below.

Where it is stated that an enhancement will be "in the Orca release" this means
that the enhancement will be delivered as part of the PowerTier/EJB version
which is code-named "Orca", and which is scheduled to be available as a beta
version on December 4/th /1998.

Where it is stated that an enhancement will be "in the Stingray release" this
means that the enhancement will be delivered as part of the PowerTier/EJB
version which is code-named "Stingray", and which is scheduled to be available
as a beta version at the end of January 1999, with additional beta releases at
the end of February and the end of March 1999.

The enhancements are classified under 2 headings:-

 .  Acceptance Criteria": these are the features that must be in the Stingray
   release in order for PowerTier/EJB to be accepted by Intershop, which in turn
   will enable Persistence to invoice Intershop for the second agreed pre-
   payment.
 .  "Required"' these are enhancements that Persistence must provide to
   Intershop, although it is acceptable for them to be made available after the
   Stingray release.

ACCEPTANCE CRITERIA
1. Unicode Support

     A mechanism will be put into PowerTier/EJB that automatically translates
     Unicode in the Java application layer into UTF8-encoded data for storing in
     the database. This mechanism will be completely transparent to the
     developer.

     When: by end of February 1999.

2. Cache Clearing

     The problem whereby EJB Beans are not cleared from the PowerTier/EJB Server
     will be fixed by the end Of February 1999.

     When: by end of February 1999.

3. Optimistic Failure Handling

     A mechanism will be provided whereby PowerTier/EJB can enable an
     application to automatically recover optimistic lock failures so that the
     object(s),that caused an optimistic lock failure can be automatically
     refreshed from the database.

Persistence Software License, Services, and Support Agreement       CONFIDENTIAL
--------------------------------------------------------------------------------

     When: By the end of February 1999.

4. Solving Java Server Toolkit Integration Problem

     This has already been achieved.

     When: closed.

5. Controlling the Visibility of Beans over the Network

     Currently all EJB Beans register with RMI, which means they are all
     'visible' to any user on the network. This is an unacceptable security
     exposure. Persistence will enhance PowerTier/EJB to: a) replace RMI
     registration with JNDI registration; and b) allow you to specify in the EJB
     Deployment Descriptor whether or not an EJB Bean is to register with JNI.
     Consequently, you will be able to completely control which beans are
     'visible' over the network and which are 'hidden'.

     When: In the Stingray release.

6. Reflection-Based Generation for Session Beans

     Reflection-based-generation will enable Java Classes that you have already
     written to be automatically transformed into EJB Session Beans.

     When: In the Orca release.

7. Reflection-Based Generation for Entity Beans

     Reflection-based-generation will enable custom methods that you have
     written to be automatically incorporated into EJB Entity Beans along with
     the methods generated by the PowerTier/EJB toolset.

     When: In the Orca release.

8. EJB Lifecycle Hook Methods

     These will be provided in the Orca release.

     When: In the Orca release.

9. Support for Java Packages

     Packages will be supported in the PowerTier Server as part of the Orca
     release.

     When: In the Orca release

                                      13
<PAGE>

Persistence Software License, Services, and Support Agreement       CONFIDENTIAL
--------------------------------------------------------------------------------

10. "Lazy-Fetch"

      PowerTier/EJB will be enhanced to provide a "Lazy Fetch" mechanism, which
      provides is a cursor-like access for the results of find XXX()-methods.

      When: In the Stingray release

11. Additional 'Find' Mechanism

      A "multi-class fetch" mechanism will be provided that enables queries to
      include 'joins'.

      When: In the 'Stingray' release.

12. Oracle 8 Client Library Support

      This will be provided in the Orca release.

      When: In the Orca release.

REQUIRED
13. Cache Synchronisation

      PowerTier will be enhanced to provide a mechanism that, in conjunction
      with a communications protocol, enables the same EJB Entity Beans
      contained in separate PowerTier Servers to be kept synchronised.

      When: In the Stingray release.

14. 2-phase commit across multiple databases from a single application server

      PowerTier/EJB will be enhanced to enable the co-ordination of 2-phase
      commits across multiple database from a single PowerTier/EJB application
      server.

      When: In the Stingray release.

15. Native Unicode Support

      In PowerTier native Unicode will be included as UCS2 in the
      Java/application Layer. This is a long term requirement.

      When: In a later release after Stingray.

                              Support Obligations

                     Persistence Technical Support Policies
                                    (Europe)

Overview

Persistence Technical Support enables you to make the most out of your software
investment by providing timely, courteous and knowledgeable support. We have
designed a Technical Support Centre to co-ordinate much of your day-to-day
interaction with Persistence Software.

These policies and procedures are the basis of our customer support commitment.
They describe in detail our support services and the procedures for you to
follow when using Technical Support. By defining clear guidelines, we aim to
simplify communications, with the goal of resolving your product questions and
problems as quickly as possible. This document also describes our policies for
the duration of support for old releases and for building patches to supported
releases.

Persistence Technical Support Centre

European customer technical support calls are handled by a local support centre
based in London. This support centre liases directly with European customers and
the Central Customer Support Centre based at our headquarters in North America.

Contacting Technical Support

You must have a valid maintenance contract in effect to use the Technical
Support Centre. Please include your maintenance contract number when you contact
the Technical Support Centre and indicate that you are based in Europe. You may
contact our Technical Support Centre by phone, email or completing the form in
the Tech Support area of the web site, using the following contact information:

Telephone: +44 171 588 4344

Email:     support@persistence.com
           ------------------------

Web Site:  www.persistence.com
           -------------------

Tracking System

All Cases and errors are tracked through an automated problem resolution system.
This is the central repository for all information about your technical contacts
with us.

Our on-line system allows us to:

[_]  Track all of our interactions with you

[_]  Track all of our efforts on your behalf as we resolve your issues

[_]  Keep detailed information on the problems you report and the questions you
     ask

[_]  Search for problem resolutions that have been documented in our Frequently
     Asked Questions (FAQ) database.

<PAGE>

Persistence Software License, Services, and Support Agreement       Confidential
--------------------------------------------------------------------------------

[_]  Maintain a customer profile on your primary and alternate technical
     contacts

[_]  Communicate case status and escalate the most important cases to senior
     Persistence engineers.

Other Sources of Information

The Technical Support Centre is also a valuable source of information. The
Support Centre will provide information on Persistence products including:

[_]  Frequently asked questions

[_]  Knowledge Base

[_]  Online User/Reference Manual

[_]  Known bugs

[_]  Release notes

Support Centre Procedures

Persistence Technical Support handles your requests using a prioritisation
process for resolving the most critical problems quickly. A Technical Support
Engineer opens your case, verifies your support contract, and records the
preliminary information. The Engineer will then give you a Case ID that you can
use for your future reference. All information related to the case is tracked
using this Case ID. Through experience or reference material the Engineer may
resolve your case during the initial contact. If this is not possible, the
Engineer may ask you to send further information, and may involve other
engineers to consult on the case.

3.1 Customer Contacts

To maintain consistent communications with you, we allow one primary and two
alternate technical contacts per development project. You assign these
individuals and are the only ones authorised to contact the Persistence Support
Centre. To change your contacts, please ask technical support for Contact Change
Request Form (CCRF). If an individual who is not on the contact list calls, we
will ask that they first call one of the assigned contacts, who will in turn
contact us.

In the case of an evaluation, we allow one client contact per evaluation. This
is the person named in the Evaluation Request Form (ERF).

3.2 Required Information

To speed handling of technical support issues, it is more efficient if you
prepare some information beforehand. The checklist below presents information
that is required before any problem resolution can begin.

[_]  Company name and contact information

[_]  Persistence Product

[_]  Persistence Product version number

[_]  Hardware platform and operating system

[_]  Database vendor and version number

[_]  Compiler vendor and version number

[_]  ORB vendor and version number (if appropriate)

[_]  Statement of the problem or question. This may also include code-fragments

Persistence Software License, Services, and Support Agreement       CONFIDENTIAL
--------------------------------------------------------------------------------

3.3  Opening a Call

All customer queries are initially recorded in our tracking system as a Call. A
Call does not have a priority associated with it. Technical Support Centre's
objective is to close all open calls as soon as possible. A call will be closed
after answering the customer's questions/queries or by escalating Calls to
Problems or Enhancement requests (see section 3.4 Opening a Problem).

3.4  Opening a Problem

A Call will be escalated to Problem status after the Technical Support Centre
has verified the problem with a supported Persistence product. The Technical
Support Centre must have your minimal test case (see section 3.5 Minimal Test
Case Information) to do this. Once a Problem is opened, the Technical Support
Centre will assign a priority based on the prioritisation criteria documented in
section 3.6 Case Priority Levels.

3.5  Minimal Test Case Information

In order for work to begin on your problem, Persistence must be able to
reproduce the condition in our own environment. In some situations, it may be
possible to reproduce your problem based on your description alone. In other
cases, we will require a minimal test case from you before we can begin work.

The minimal test case represents the minimum application required to reproduce
the problem:

---------------
Object Model     Your persist file with a maximum of 5 classes
---------------

---------------
Test case code   main.cpp program with no more than 50 lines which reproduces
---------------  your problem

---------------
Makefile         A simple Makefile to build your test case
---------------

---------------
Modified         If your problem involves methods added to Persistence
Generated Code   generated code, include the relevant modified generated files
---------------

---------------
Client           If your problem involves a three-tier architecture, be sure
---------------  to include simplified client files


                          Figure 1 - Minimal test case

Until we receive the necessary information to duplicate the reported problem in
our Technical Support Centre, work cannot begin on problem resolution. In
addition, cases which contain more than five classes or which involve
significant amounts of code not related to the problem may be placed at a lower
priority for resolution.

--------------------------------------------------------------------------------


Once a minimal test case has been received by the Technical Support Centre and
reproduced by the Technical Support Engineer, the Case ID will be assigned a
priority (i.e. P1, P2, P3, and P4), which will determine when resources are
assigned to fix the problem.

3.6    Case Priority Levels

Persistence prioritises your case based on its severity. Cases with severity
levels of P1, P2, or P3 are automatically escalated to more senior engineering
resources if they are not resolved within the specified time period (See Table 1
- Problem resolution goals). In order for cases to be prioritised, they must be
submitted along with a minimal test case.

The following diagram illustrates the decision tree for determining case
priorities:

                                              --Yes-- P1 Priority


                                          Stop Work
                              --No--    on production        --Yes-- P2 Priority
                                           system?
-----------------
     Customer                                             Stops work
   problem with  --  Work-around              --No--    on development
minimal test case     available?                            system?
-----------------

                              --Yes--   P4 Priority           --No-- P3 Priority


                           Figure 2 - Priority levels

3.6.1  Case Priority P1
-----  ----------------

When you have an emergency in a production system that stops work, the Technical
Support Centre prioritises your case as P1. 'Stops work' means that production
work has halted and cannot continue. This priority allows us to immediately
direct your case to the Engineer with the correct expertise. When the
appropriate Engineer is not immediately available, our goal is to have contacted
you to begin problem resolution within one hour after we have received a minimal
test case.

P1 cases without resolution or work-around within one day of receiving a test
case are immediately escalated to a Senior Engineer and management.

3.6.2  Case Priority P2
-----  ----------------

When you have a condition in a development system that stops work, the Technical
Support Centre prioritises your case as P2. 'Stops work' means that further
development work has halted and cannot continue. This priority allows us to
immediately direct your case to the Engineer with the correct expertise. When
the appropriate Engineer is not immediately available, our goal is to have
contacted you to begin problem resolution within two hours after we have
received a minimal test case.

<PAGE>

Persistence Software License, Services, and Support Agreement       CONFIDENTIAL
--------------------------------------------------------------------------------


P2 cases without resolution or work-around within two days of receiving a test
case are escalated to a Senior Engineer and management.

Note: During P1 and P2 problem resolution there will be ongoing communication
providing status and information exchange to facilitate resolution of the
problem.

3.6.3 Case Priority P3
----------------------

When you have a condition in a development or production system that does not
prohibit progress, for which there is no work-around, the Technical Support
Centre, prioritises your case as P3. A 'work-around' is a known solution to
resolve the condition. This priority--allows us to devote resources to
identifying a work-around. Our goal is to have contacted you to begin problem
resolution within four hours after we have received a minimal test case.

P3 cases without resolution or work-around within 1 week of receiving a test
case are escalated to a Senior Engineer and management.

3.6.4 Case Priority P4
----------------------

When you encounter a known condition in a development or production system for
which there is a robust work-around, the Technical Support Centre prioritises
your case as P4. Our goal is to have contacted you regarding this issue within
one day. This condition will be addressed in a scheduled release of Persistence.

The following table summarises the response goals of the Technical Support
Centre. Note that in all cases, a minimal test case is required.

-------------------------------------------------------------------------------
Case priority                    Initial           Respond with Work-around or
                                 contact within    commitment within
-------------------------------------------------------------------------------
P1 - stops production            1 hour            2 working days

P2 - stops development           2 hours           3 working days

P3 - no work-around              4 hours           1 week

P4 - work-around exists          1 day             N/A

                       Table 1 - Problem resolution goals

3.7 Patches to Resolve Problems

Once the Technical Support Centre has verified a problem your Case ID will be
given a priority. When requested, Persistence will endeavour to provide patches
to P1, P2, and P3 priority problems on supported versions of Persistence
products (see section 0, 'Duration of Support for Releases'). In some cases,
patches may not be possible and you will be required to upgrade to a more recent
version of the product.

For P1 and P2 problems Persistence will create, build, and test a patch as
quickly as possible, usually within 3 days of problem verification. P3 problems
will be resolved in a subsequent product release. P4 problems may be resolved in
conjunction with other product enhancements.

The table below summarises the goals for the delivering patches. The time
periods begin when the Technical Support Centre has verified the problem:

--------------------------------------------------------------------
Case priority                          Goal for delivering patch

<PAGE>

Persistence Software License, Services, and Support Agreement       CONFIDENTIAL
--------------------------------------------------------------------------------

P1 - stops production    within 3 working days

P2 - stops development   within 4 working days

P3 - no work-around      in subsequent release

P4 - work-around exists  as part of other enhancement

Table 2 - Patch delivery goals

3.8 Escalation to a Manager

Whenever the Persistence Technical Support Centre is not meeting your needs or
expectations, you may escalate the case or any other issue to the Technical
Support Centre Manager. You may also contact the Technical Support Centre
Manager if the case becomes too complex or you become concerned that our
Engineers are not able to resolve the case in a suitable manner.

3.9 Requesting an Enhancement

Each enhancement request will be assigned a Case ID. This will allow us to track
your request and to inform you when the enhancement is available.

Duration of Support for Releases

The Persistence Technical Support Centre will provide responses (as described
above) for supported releases. The duration of support will vary depending on
the type of release. Persistence defines three types of releases:

General Availability (GA)

A GA release will be sent to all customers who have current support contracts.

A GA release will be supported for the longer of:

[_]  18 months

[_]  One year after the next GA release.
Beta

Beta releases will be sent to customers who have been selected to participate in
the beta program.

Beta releases will not be supported beyond the shipment of the next GA, or Beta
release. Therefore, Persistence recommends that Beta releases be not used for
shipment of production systems.

Alpha

Alpha releases are sent in rare situations to satisfy urgent customer needs.

Alpha releases will not be supported beyond the shipment of the next GA, Beta,
or Alpha release. Therefore, Persistence recommends that Alpha releases be not
used for shipment of production systems.

Support for New Versions of Operating Systems, Databases, Compilers, ORBs, and
Class Libraries

Persistence intends to provide one or two GA releases per year. Persistence
attempts to support any configuration that is commercially available (i.e. not
in Beta) 60 days prior to the scheduled GA

                                      10
<PAGE>

Persistence Software License, Services, and Support Agreement       CONFIDENTIAL
--------------------------------------------------------------------------------

release of Persistence Products. Persistence will support the important new
features of the new operating system, database, compiler, ORB, and/or class
library as they may apply to various Persistence products.

Support for Old Versions of Operating Systems, Databases, Compilers, ORBs, and
Class Libraries

Persistence products interact with and depend on operating systems, databases,
compilers, ORBs, and/or class libraries. As new versions of the products are
available, Persistence will discontinue support for old version of these
products. This section describes the policy for terminating our support of a
particular release of an operating system, database, compiler, ORB and/or class
library.


Operating Systems

New releases of Persistence products will continue to support an old version of
an operating system for one year after a GA release of Persistence product is
available that supports the new version of the operating system.

Databases

New releases of Persistence products will continue to support an old version of
a database for one year after a GA release of Persistence product is available
that supports the new version of the database.

Compilers

New releases of Persistence products will continue to support an old version of
a compiler for six months after a GA release of Persistence product is available
that supports the new version of the compiler.

ORBs

New releases of Persistence products will continue to support an old version of
a ORB for six months after a GA release of Persistence product is available that
supports the new version of the ORB.

Class Libraries

New releases of Persistence products will continue to support an old version of
a class library for six months after a GA release of Persistence product is
available that supports the new version of the class library.
