1.   First Year Annuncio Live License Fee- Up to [*] marketing transactions /
     year: [*]

2.   First Year Annual Maintenance Fee: [*]

3.   Dealer Fees:


  .  Licensee shall pay Annuncio an additional fee for new Customers who license
     Licensee Services ("Dealer Fees"), based on the number of automobile
     dealership franchises the Customer owns according to the following
     schedule:


               Number of Franchises                Fees
               -----------------------------------------

               10 +                                [*]


  .  [*]

  .  Dealer fees Payable net 60 days from the day the dealership contract is
     signed.

4.   Payment

 .  [*] of licensing and maintenance fees will be paid at time of signing, net 30
   days

 .  Once the Software is [*], Bridge will pay an additional [*] of the licensing
   and maintenance fees, net 30 days. The remaining [*] of licensing and
   maintenance fees are due 30 days from the day of acceptance, net 30 days;
   annual maintenance fees are due according to the standard Annuncio licensing
   contract.

 .  [*]

5.   Deployment Criteria:

A.  Within scope of license:
The parties agree that the following scenarios identify the situations which are
within the scope of the license as set forth in Section 2.1 of this Agreement:

 .  Customer Requirements - Customers may demand to be put on separate physical
   boxes due to security concerns. This could be particularly true with large
   dealership groups.

 .  Performance Constraints -Wide geographic deployment (i.e., regional,
   international, global) may require regional operating sites in order to
   maximize performance. For example, UK dealers may not be satisfied with
   response times associated with a US-based server.

 .  Reliability Considerations - Backup, maintenance, rollover and disaster
   recovery capabilities are integral to a robust system and should not
   interfere with EMA performance. Multiple production sites would insure this
   requirement.

                                       9

[*] = CERTAIN INFORMATION IN THIS EXHIBIT HAS BEEN OMITTED AND FILED SEPARATELY
WITH THE COMMISSION. CONFIDENTIAL TREATMENT HAS BEEN REQUESTED WITH RESPECT TO
THE OMITTED PORTIONS.
<PAGE>

 .  Development/Test/Mirror Site - One or more independent
   development/integration environments will be required. Non-production testing
   environments may also be required. In addition, one or more mirror sites may
   be required for backup/recovery and/or operational considerations (e.g.,
   customer FTPs)

 .  A Single Instance of the Application Cannot Scale Adequately - The EMA
   application as a whole or particular sub-applications may not be able to
   scale in a single instance and we would have to deploy multiple instances of
   the application on multiple hardware platforms. An example is to exceed the
   application's internal limitations on number of transactions, array size,
   number of threads spawned, etc. The limitations are specific to the software,
   not the hardware.

 .  A Single Box and/or Supporting Infrastructure Cannot Handle Required Scale -
   The hardware supporting the EMA application as a whole, or particular sub-
   applications, may not be able to scale sufficiently and we would have to
   deploy multiple instances of the application on multiple hardware platforms.
   Examples include: exceeding processing power, bus architecture limitations,
   memory limitations. These limitations are specific to the hardware, not the
   software.

B. Outside Scope of license:
The parties agree that following scenarios represent situations which are
outside of the scope of the current license as set forth in Section 2.1 of this
Agreement:

 .  Diversified Customer Base - The license will not apply to non-dealer
   customers (e.g., auto manufacturers, web portals, non-automotive industry).
   These markets will require a separately negotiated application license.

 .  Sublicensing of Software without hosting: The parties agree that Licensee may
   sublicense the Software solely to Customers, subject to the restrictions set
   forth in the Base Agreement.

6. Future License Options:  The following future pricing shall be in effect for
three years from the Effective Date of this Agreement:

                                 Specifications

The following criteria are issues that Bridge Telecom feels are essential for
providing Annuncio as a fully hosted solution to the automotive dealer
marketplace.

Integration Issues

As part of a larger solution, the Annuncio software must be flexible and fully
able to integrate with other standard software solutions. In particular, it is
vital that the Annuncio Live software platform:

 .  Provide access to Annuncio Live data needed to integrate with standard CRM
   vendors (e.g. Onyx, Pivotal, Silknet, Vantive, Siebel) or other systems

 .  Provide the flexibility to import/export customer data (e.g., demographics)
   that is compliant with the product's business rules

Hosting architecture

Bridge Telecom plans to provide its services at a price point that is acceptable
to the small business community. Central to this goal is that the Annuncio
architecture be able to [*]. That is, for a single installation of the Annuncio
Live software:

 .  The Product must be logically partitionable by dealer -- It must be possible
   to [*]. If this is not a native feature of the system, then it must be
   possible to invest a reasonable amount of effort (e.g. by Bridge Telecom) in
   supporting this model by building customized interfaces to the system or
   otherwise.

 .  The product must also be fully secure -- All reasonable security measures are
   expected from the product. In addition, it must be possible to build the
   logically partitioned system described above in a manner that prohibits a
   dealer's data or campaigns to be viewable by any unauthorized party (e.g.
   another dealer or other user of the system)

Scalability

Bridge Telecom expects Annuncio Live to be a highly scalable product. This
includes scalability in terms of large numbers of named users, named subscribers
as well as volume of transactions on the system. In particular, there should be

 .  No unreasonable limits on logical scalability -- A logical limit is defined
   as a hard limit unnaturally imposed by the software. For example, a fixed
   array size that only accommodate 20 dealers.

 .  No unreasonable limits on physical scalability -- No system is infinitely
   scalable. There will always be limits in terms of bandwidth, storage or
   processing power. However, it is expected that the Annuncio Live product
   shows all the characteristics of a highly scalable system.

The following list contains many of the dealer campaigns that Bridge Telecom
plans to roll out initially. Our offer is based on the ability to aid
dealerships in moving forward into the arena of electronic communications, email
management, and greater responsiveness to their customer base.

 .  Acquire -- The first stage for dealers who do not have email addresses or for
   dealers who want to expand the number of available customer email addresses.

 .  Categorize and Manage -- Learn more about your existing e-customers. Segment
   them appropriately by their interests. Set up targeted, personalized
   campaigns.

 .  Implement -- Launch direct campaigns based on known customer information and
   preferences. Automate this process as much as possible.

 .  Measure Results -- Analyze the impact of your campaigns. Evaluate your
   response rate and ROI. Aid in planning for new campaigns.

Dealer Campaigns

Basic Campaign (Newsletters)

This replaces/augments the traditional periodic newsletter. It has the following
components/advantages:

 .  Automated, electronic delivery -- Customers can choose to receive only an
   email newsletter and not a snail mail hard copy.

 .  Electronic advertising banners and coupons -- Customers can be presented with
   specials, coupons and incentives of general interest. [*]

 .  Complete a survey, refer a friend -- Newsletters can direct customers to the
   dealer website to fill out a more complete survey, to take advantage of
   specials or to provide referrals.

 .  Customer info database/ reports -- Newsletters will have [*]

Direct Mail Integrated Campaigns

Many customers will immediately wish to move to an electronic, interactive means
of staying in contact with the dealer. Others will be hesitant and will want to
stay on direct mail. There must be campaigns to support both of these. An
electronic campaign that supports direct mail will:

 .  Produce unique URL's for customers to come and sign up for features on the
   website

 .  Provide incentives in direct mail to have customers enter their email
   addresses into the system

 .  Provide an interface for staff at the dealership to enter collected email
   addresses

Targeted Service Reminders and Promotions

[*] = CERTAIN INFORMATION IN THIS EXHIBIT HAS BEEN OMITTED AND FILED SEPARATELY

<PAGE>

An important feature of this system is to be able to deliver to customers the
information that they are interested in. Likewise, the dealer can act as a
personal reminder service for tune-ups, oil changes and other incentives.

 .  Electronic scheduled service reminders (tailored to customer)

 .  Targeted coupons/promotions w/ specials

 .  Mileage forecast (culled from survey) to trigger service messages

Alert for Sign-ups (parts, car availability), Events

Customers often wish to be alerted when a specific event occurs. This can be
dealer events, alerts about the availability of new cars (e.g. send me an email
to let me know when you get your s2000's in) or a notice about when a part is
available.


 .  [*]

 .  Email to list subscribers at regular intervals

Recall Notices

Recall notices have always proven to be a popular item for customers. One
effective way of getting the email of dealer customers is to have them sign up
for targeted email that affects their particular vehicle and prompts them then
with special service offers for their recall.


 .  Targeted notices

 .  [*]

 .  Question: Is it possible to integrate the above with voicemail?

Surveys and Suggestion Boxes

Targeted surveys are an effective way of getting information about new and
existing customers. Surveys can be automatically tailored to the
needs/requirements of the customer. This is also the most effective way to begin
and know your customers.


 .  [*]

 .  [*]

 .  Targeted marketing campaigns based on above (e.g. all '93 civics -- want to
   upgrade?)

<PAGE>

Maintaining a relationship that begins with a car sale can be very lucrative for
a dealer in gaining not just a new customer but a new loyal customer.

 .  Follow-up campaigns based on preferences, purchase specifics

 .  Alerts (e.g. notify me of S2000 availability if any) even as special requests

Personal Events Based Offers

Based on birthdays and other special events, the dealership can automatically
offer special birthday and other offers.

 .  Birthdays

 .  Anniversaries

Simple Help-Desk Support

Providing customers with at least a little help when they ask for it is always
invaluable. Customers on the web asking for help can be easily integrated with
their email identity.

 .  Targeted (by request) technical service bulletins
 .
   Web-based Ask the Mechanic (queued questions)

Service/Warranty Contract Expirations

As customers near the end of a warranty or contract, the system can notify them
immediately and make them a special offer to extend their warranty with the
dealer.

 .  [*]
   Integrated Manufacturer Campaigns

As news become available from the manufacturer, this information can be routed
directly to those customers that are interested in it.


 .  Integrate with Manufacturer specific campaigns

 .  Recall notification

 .  Update interested customers (get their VIN, address email)


Purchase Offers

                                       15

[*] = CERTAIN INFORMATION IN THIS EXHIBIT HAS BEEN OMITTED AND FILED SEPARATELY

THE OMITTED PORTIONS.

<PAGE>

Based upon customer information, dealers can also submit purchase offers
directly to their customers. For example, "Did you know your 91 CRX was
worth...?"

Stale Customers

Customers who have not had interaction with the dealership for a while can be
targeted with special incentives to return. This is the focus of Internet
loyalty programs.

 .  Special offers

 .  What did you buy?

 .  We can service any car.

 .  Targeted comments/questionnaires
