DELIVERY PARAMETERS
1.       Real time services, such as Company News Report, which is breaking news
         on a company, and Sports Results, which are final scores, are delivered
         as they are available.

2.       All other Services have a daily default window of delivery time, to be
         selected by the Subscriber.

3.       All services, whether real time or otherwise, are subject to the
         Subscriber-specific global parameter, which will override all others.
         For example, "Deliver between 8 a.m. and 10 p.m. Monday - Friday and
         between 10 a.m. and 11 p.m. Saturday - Sunday" overrides real time
         delivery. In this case, no real time services will be delivered outside
         the subscriber's global parameters, 8 a.m. - 10 p.m. M-F and 10 a.m.
         -11 p.m. Sat-Sun.

4.       Some services are available daily and some only on business days, as
         outlined below.

5.       The customer may suspend all services using the web interface without a
         financial impact. That is, a customer may suspend their information
         services themselves for a period of time, but they will continue to be
         charged for the feature. When Customer Service suspends the service,
         due to non-pay for example, there is a revenue impact. III will no
         longer charge SBMS for that subscriber.

AVAILABLE SERVICES AND DELIVERY SCHEDULE

III will make available to SBMS the services listed below. The delivery schedule

    services are only subject to the subscriber's global delivery parameters.

-   Scheduled Delivery means the information is delivered at the subscriber's
    pre-established time periods.

-   Frequency is the numbers of time/day that the information is delivered.

-   Daily Delivery means the information is delivered 7 days a week, Sunday
    through Saturday.

    only, usually Monday through Friday, with no delivery on Saturday, Sunday or
    holidays.

"POWERED BY iii" GUIDELINES FOR USE


         The Value of "Powered by iii"

-    The "Powered by iii" Logo (the "Logo") is an effective way to identify
     information services offering as incorporating the benefits and features of
     the leading source of personalized content for wireless devices,
     Intelligent Information Incorporated (III).

-    Use of the Logo also qualifies resellers to participate in III's advanced
     business partner support programs.

         The Logo's Meaning for Business Partner Use

-    The Logo conveys the value and excitement of personalized information
     services provided by the III platform. Business partners may use this Logo
     in advertising, point-of-purchase displays, and marketing materials to
     promote information services. The Logo may only be used according to these
     Guidelines. These Guidelines help ensure that the Logo continues to provide
     consumers with a clear identification of information service quality.

-    To protect this valuable trademark, the business partner may not use the
     Logo in any way other than as described in these guidelines or as may be
     provided in writing by III from time to time. Any unauthorized use of the
     Logo is an infringement of III's trademark rights.

         Business Partner Logo Artwork

-    Do not use artwork provided by any source other than III. III will provide
     approved Business Partners that agree to follow these guidelines with
     electronic versions of the Logo. You may not alter this artwork in any way,
     separate the words from the graphic, or replace the words with any others.
     The trademark symbol ((TM)) must appear at the lower right corner of the
     graphic portion of the Logo. Documents including the Powered by iii logo
     must also include the footnote, in no less than 6 point text, "Powered by
     iii is a registered trademark of Intelligent Information Incorporated."

         Sizing and Placement Requirement

-    The Logo may be used only on materials that make accurate references to the
     information services as provided by III. The Logo must be placed in close
     proximity to headline copy or logo treatments dealing with information
     services. The Logo cannot be larger or more prominent than your company
     name, company logo, product name (if applicable), or service name.

-    The Logo may stand-alone, or be incorporated into your information services
     logo if appropriate. If the Logo is used as a stand alone element, a
     minimum amount of empty space must be left between the Logo and any other
     object such as type, photography, borders, edges, etc. The required border
     of empty space around the Logo must be 1/4x wide, where x equals the height
     of the graphic, as measured from the highest point on the graphic portion
     of the Logo to the lowest point on the graphic portion of the Logo.

-    Minimum size for the Logo is 3/8 of an inch high.

-    Business partners may not use the Logo in any manner that suggests that
     advertising, point-of-purchase displays, or other marketing materials are
     from III.

<PAGE>   24

-    The footnote "Powered by iii is a registered trademark of Intelligent
     Information Incorporated", in not less than 6 point type, must accompany
     each use of the Logo.

-    Intelligent Information Incorporated reserves the right to object to unfair
     uses or misuses of its trademarks or other violations of applicable law.

         Color Treatment

-    You may not alter the colors of the Logo in any way from the treatments
     provided by III, without the written approval of III.

         Quality Control

-    III reserves the right to review business partner use of the Logo. Business
     partner must correct any deficiencies in the use of the Logo upon
     reasonable notice from III.

     Manager or III's Director of Marketing.

     the guidelines as amended from time to time.

     change in its Logo or guidelines, provided III requires SBMS not to utilize
     existing materials.
