Re:  i3 Mobile, Inc.

Dear Kris:

This letter sets forth the understanding between i3 Mobile, Inc. (the "Company")
and AT&T Wireless Services, Inc. ("AT&T") pursuant to which the Company will
provide incentives for AT&T should they choose (a) to develop and implement with
the Company a program for tagging messages with advertising and (b) to increase
penetration for the Company's services with AT&T's new and existing customer
base. The terms of our understanding are as follows. If AT&T decides to develop
a program it will have the following characteristics:

1.   The program will be designed to tag messages with advertisements. The
     program will be implemented on a test basis in markets defined by AT&T and
     expanded to all markets as may be determined in good faith by AT&T based on
     its analysis of the success and viability of the test program.

2.   The program will be designed to send "welcome" messages for Personal News
     Complimentary Service to all subscribers that are new to AT&T Wireless and
     to all existing subscribers that have not previously had SMS provisioned on
     his or her phone (collectively, "new subscribers").

3.   The program will be designed to send a "reminder" message for Personal News
     Complimentary Service to at least fifty percent (50%) of the existing
     customer base that is provisioned with SMS capabilities but has not
     subscribed to any Personal News service (collectively, "existing
     subscribers"). Under the program, AT&T and Company will work to identify
     qualifying target customers. The Company will prepare a reminder broadcast
     message acceptable to AT&T informing the subscribers that their
     complimentary services are activated and may be accessed through the AT&T
     Wireless Netcare site.

4.   In consideration of AT&T's services set forth in paragraphs 1, 2 and 3
     hereof, the Company agrees to issue to AT&T warrants (the "Warrant") to
     purchase up to 200,000 shares of the Company's Common Stock at an exercise
     price equal to fifteen ($15.00) dollars per share. The Warrant shall vest
     as follows:

         (a) 10,000 shares upon the performance of AT&T's obligations under
paragraph 1 hereof;

         (b) 20,000 shares for every 200,000 new subscribers that are sent
"welcome" messages for Personal News Complimentary Service and become registered
subscribers to the Personal News Complimentary Service provided by the Company,
up to a maximum of 140,000 shares; and

         (c) 10,000 shares for every 200,000 existing text-messaging subscribers
that are pre-provisioned to subscribe to the Personal News Complimentary Service
and become registered subscribers to the Personal News Complimentary Service
provided by the Company, up to a maximum of 50,000 shares.

5. Full terms and conditions of the warrants will be included in a separate
Warrant Agreement to be negotiated by the parties.

Should the foregoing accurately reflect our understanding, then kindly
countersign and return the enclosed copy of this letter to my attention.

Very truly yours,
i3 MOBILE, INC.

Re:  i3 Mobile, Inc. - Letter of Intent

Dear Mark:

This letter sets forth a proposal to pursue further negotiations and discussions
leading to a definitive agreement between SPORTSLINE.COM, INC.
("SPORTSLINE.COM") and i3 Mobile, Inc. ("i3"). The proposed arrangement will
require further documentation and approvals, including the preparation and
approval of a definitive agreement setting forth the terms and conditions of the
business relationship (the "Agreement"). Nevertheless, i3 and SPORTSLINE.COM, by
signing below, execute this letter to evidence their intentions to proceed in
mutual good faith to complete the work required to negotiate the Agreement on
terms that are consistent with this letter.

In our view, i3 is uniquely positioned to work with SPORTSLINE.COM to develop
the value of SPORTSLINE.COM wireless information and product offerings. The
proposed terms and conditions include, but are not limited to, the following:

1.   LICENSE GRANT: During the term of the Agreement, i3 shall serve as the
     exclusive integrator of SPORTSLINE.COM's wireless information services from
     the CBS SportsLine site. The Agreement will define the exclusivity
     contemplated. The exclusivity language will not require SPORTSLINE.COM to
     utilize the services of i3 should a carrier or OEM require that
     SPORTSLINE.COM utilize a select ASP that is not i3 to deliver content to
     that carrier or OEM. SPORTSLINE.COM will first request that any such
     carrier or OEM company utilize i3. Furthermore, nothing contained in the
     Agreement will restrict SPORTSLINE.COM's right to license content to other
     entities for distribution in any medium, including other wireless
     platforms.

2.   TERM: The term of the Agreement shall be three (3) years beginning on the
     Effective Date. The Effective Date of the Agreement shall be either (a) the
     date the Agreement is fully signed by the parties; or (b) the date of the
     first wireless service launch contemplated hereunder, whichever is later
     provided that any delay is not caused by i3. SPORTSLINE.COM shall have the
     right, in its sole discretion, to terminate the Agreement on the 18 month
     anniversary of the Effective Date by paying i3 $375,000. The parties agree
     to translate the terms of this letter into the Agreement within 30 days of
     the signing of this letter.

3.   GEOGRAPHIC SCOPE: The Agreement shall cover the CBS SportsLine Web Site for
     distribution within the US and Canada only. In any other geographic areas
     covered by companies with whom SPORTSLINE.COM has an affiliated company,
     SPORTSLINE.COM will exercise all reasonable
<PAGE>   2

     efforts to introduce i3 to that affiliated company so that i3 can negotiate
     an agreement on terms agreeable by all parties.

4.   DEVELOPMENT FEE: Immediately upon execution of the Agreement, i3 shall work
     with SPORTSLINE.COM to design the Wireless Portals for the SPORTSLINE.COM
     service. Wireless Portal(s) will be defined as the presentation of content
     and advertising displayed on a wireless devise and does not include any
     pages on the SPORTSLINE.COM Web Site, including, but not limited to, pages
     dedicated to promotion and personalization/activation of the wireless
     devices. SPORTSLINE.COM shall pay i3 the sum of $100,000 for the
     development of this web site. For the $100,000 payment, the following
     services will be included:

     -    Technical design, development, testing and implementation of the
          wireless portal (including all provisioning pages which will include
          the ability to access audio content) pursuant to the proposed product
          plan attached as Exhibit I. In addition, i3 will develop additional
          products requested by SPORTSLINE.COM and approved by i3 (which
          approval shall not be unreasonably withheld) at a mutually agreed upon
          cost. To the extent i3 will not agree to develop such product,
          SPORTSLINE.COM will be relieved of its exclusivity obligations to i3
          with respect to such product.

     -    I3 will provide best efforts to ensure that the Wireless Portal is
          maintained in accordance with the highest industry standards on a
          24/7/365 basis - i3 Mobile Wireless Customer Care Set-Up

     -    In-house training of SPORTSLINE.COM's staff relating to customer
          service procedures and policies

     -    FAQ (Frequently Asked Questions) online document

     -    Second level customer support including access to i3 staff on a 24/7
          basis, at SPORTSLINE.COM's election, i3 will handle first level
          customer support and/or assist SPORTSLINE.COM in such first level
          customer support.

5.   PAYMENTS BY i3: In consideration of the rights granted by SPORTSLINE.COM to
     i3 in Paragraph 1, i3 agrees to pay SPORTSLINE.COM as follows: $300,000
     upon execution of the Agreement and an additional $200,000 on the
     anniversary of the second year of this Agreement.

6.   WARRANTS: In consideration of the rights granted by SPORTSLINE.COM to i3 in
     Paragraph 1, i3 shall issue to SPORTSLINE.COM warrants (the "Warrant") to
     purchase 20,000 shares of i3's Common Stock at an exercise price equal to
     fifteen ($15.00) dollars per share. The Warrant shall vest 50% upon
     execution and 50% on the 18 month anniversary of the deal (provided SPLN
     does not exercise it's termination right) and shall expire three (3) years
     following its issuance and shall not terminate upon an initial public
     offering or change of control of the Company. Subject to any relevant
     securities laws, rules and regulations, the Warrant, as well as the Common
     Stock acquired through exercise thereof, will be freely transferable by
     SPORTSLINE.COM and may be exercised in whole or in part. When exercising
     the Warrant, SPORTSLINE.COM shall have the right to either (a) purchase the
     total number of shares of Common Stock which such Warrant entitles
     SPORTSLINE.COM to purchase at the exercise price described above or (b)
     receive the net number of shares of Common Stock arising from the
     difference between the market price of such Common Stock at the date of
     exercise and the exercise price of the Warrant. Prior to the grant of the
     Warrant hereunder, i3 will provide SPORTSLINE.COM with an opportunity to
     review i3's standard Warrant form prior to execution. I3 and SPORTSLINE.COM
     will mutually agree upon the registration rights of the Warrant among other
     things currently contemplated to be piggyback rights.

7.   MARKETING FUNDS: In consideration of the rights granted by SPORTSLINE.COM
     to i3 in Paragraph 1, i3 shall pay SPORTSLINE.COM $200,000 upon the launch
     of the Wireless Portal during Year 1 of the Agreement, $225,000 on the
     anniversary date for Year 2 of the Agreement and $275,000 on the
     anniversary date for Year 3 of the Agreement. A marketing plan will be
     developed to use these funds to promote the wireless products on
     SPORTSLINE.COM and the funds will be released in accordance with this plan.
     In order to match i3's contribution to the marketing of said products,
     SPORTSLINE.COM will charge i3 a rate of $15 CPM that is half the normal
     rate for said advertising.

     SPORTSLINE.COM's products and based upon the product plan set forth in
     Exhibit I. The net revenue from such subscription-based products will be
     divided equally between the two parties. SPORTSLINE.COM will use
     commercially reasonable efforts to promote and advertise the wireless
     portals and products and to encourage subscription growth through the
     various media sources it has access to.

9.   CONTENT LICENSING: During the term of the Agreement, i3 shall have the
     right to distribute the SPORTSLINE.COM content to create additional
     wireless products that will be branded with a SportsLine.com brand and will

     revenue equally through the licensing of SPORTSLINE.COM content after
     deducting the cost of any third party content license fees incurred by
