        Re: Projects covered by the Broadcast Entertainment.com agreement.

Gentlemen:

        Reference is made to the Master Content Provider Agreement (the
"Agreement") dated 9 February, 2000 between i3 Mobile, Inc ("i3") and Broadcast
Entertainment.com, Inc. ("BE"). Mobile Media Group, Inc. ("MMG") is the
successor in interest to all of BE's rights and obligations under the Agreement.
MMG and i3 have been working together in connection with a number of MMG
initiatives, some of which may not clearly fall within the definition of
"entertainment related areas" described in Appendix "A" of the Agreement. It is
the desire of i3 and MMG to regularize their relationship with regard to such
initiatives, and, accordingly, i3 and MMG agree that the Agreement is hereby
amended as follows:

1.  Those projects which may be separately designated in writing by MMG which
    include the parties described in Exhibit "A", attached hereto and by this
    reference made a part hereof, are acknowledged to be MMG initiatives and
    are, together with those future mobile projects designated in writing by MMG
    which include either the same or related third parties, referred to herein
    as the "Projects". It is expressly understood and agreed that MMG shall only
    have the right to designate hereunder as "Projects" those initiative and
    projects which have at least reached the stage of a preliminary letter of
    understanding on or before December 31, 2001.

2.  Notwithstanding anything to the contrary contained in the Agreement the
    Projects are deemed, for all purposes, included as so called "entertainment
    related areas", and, accordingly are and will continue to be fully subject
    to the mutual exclusivity clauses of the Agreement and, where applicable,
    all other provisions of the Agreement relating to content, data or
    transactional services where MMG (or BE) is the sole aggregator thereof.
    Both the economic terms and i3's participation for each Project shall be
    subject to good faith negotiation between the parties on a case by case
    basis; provided, however, that, in the event i3 agrees to participate in a
    Project but the parties can not agree on economic terms, then the parties
    can either (a) mutually agree to proceed on the economic terms (i.e.
    60%-40%) described in the Agreement or, (b) rescind the designation of the
    applicable initiative or project as a Project hereunder and , subject to the
    timeframe set forth in paragraph 1, MMG shall be entitled to pursue each
    such opportunity with other third parties, and i3 shall have no right to
    pursue such opportunity with the same or any other third party, and the
    parties shall be deemed to have executed a standard Non-Disclosure/ Non-Use
    Agreement with regard to information disclosed, including exclusions
    customarily included in such agreements.

3.  It is the intent of this amendment that MMG and i3 will continue to work
    together, on an exclusive basis on all present and future mobile development
    for all third party companies participating in the Projects and all future
    efforts derived, out of the Projects, and all corporate relationships
    developed as a part of such Project.

4.  Except as expressly set forth herein, the Agreement shall remain in full
    force and effect, and both parties hereto acknowledge and agree that MMG
    shall have all of the rights and obligations of BE thereunder.

        If the forgoing is in accordance with your understanding, please so
indicate by signing hereinbelow.

AGREED TO AND ACCEPTED:

Interactive acquires the right to distribute Content provided or made
available as part of the Service.

        (c)    "Designated Resellers" means SBC Communications and any other

Interactive, and (iii) any other articles of interest provided by MSNBC
Interactive.

        (e)    "Service" means i3's delivery of personalized information to

        (f)    "Users" means all third parties to whom i3 Mobile may license,
sell, transfer, make available or otherwise distribute the Service.

2.      GRANT OF LICENSE. Subject to the terms and conditions of this Agreement,
MSNBC Interactive grants i3 Mobile a non-exclusive, non-transferable license to
distribute the Headlines only through the Designated Resellers that have been
approved by MSNBC Interactive (per section 1(c) above) in North America solely
for the purpose of being viewed on Users' wireless devices such as mobile
telephones and personal digital assistants. Each Designated Reseller shall have
the right to market and distribute the Headlines solely to such Designated
Reseller's subscribers.

3.      OBLIGATIONS OF I3 MOBILE.

(a)     Fees. In consideration for the services to be rendered by MSNBC
Interactive herein, i3 Mobile shall pay MSNBC Interactive Fifty Thousand Dollars
(US$50,000.00) upon the execution of this Agreement.

(b)     Attribution to MSNBC Interactive. i3 Mobile shall include attribution to
MSNBC Interactive with respect to each Headline made available to Users

<PAGE>   2

text that is of a point size equal to that of the related Headline. i3 Mobile
shall require that all Designated Resellers pass through such attribution to
Users without alteration.

(c)     Preferred Placement. i3 Mobile guarantees that the Headlines provided by
MSNBC Interactive hereunder shall be the exclusive news and entertainment
content appearing on the free tier of Designated Resellers wireless data
services. To the extent technically feasible within i3 Mobile's wireless
platform, the Headlines shall be accorded Preferred Placement (as defined below)
in the news and entertainment categories on all other platforms on which the
Headlines are placed; provided, that such Preferred Placement shall not be
subject to any exclusivity or Preferred Placement for such type of content which
has been contracted for prior to the Effective Date by a third party not
affiliated with i3 Mobile. Preferred Placement shall mean (i) where a link to or
display of a Content appears on a list, such link or Content is in the default,
top-most and left-most position; or (b) when a link to or display of Content
appears in a format other than a list, the link or Content is more visually
prominent, or at a higher rate of exposure, than other Content Providers.

(d)     Technology and Back-end Processing. i3 Mobile shall be responsible for
all hosting and delivery of the Headlines, technical support, contractual
arrangements with Designated Resellers and other necessary parties, customer
service and all other issues involved in managing the relationship with

delivered to Designated Resellers on a timely basis, but in any event within ten
(10) minutes of their scheduled delivery to Users.

(e)     Marketing. i3 Mobile will ensure that MSNBC Interactive receives (i)
marketing support equal to that of any other content provider appearing within a

equal to that made available to any other similarly situated provider on each
additional platform on which the Headlines appear. At any time during the Term
(as defined below), MSNBC Interactive may request, and i3 Mobile shall promptly
provide, an officer's certificate certifying that i3 Mobile has been and remains
in compliance with this Section.

(f)     Promotion. Subject to the provisions of the letter agreement, dated
December 29, 1999, between i3 Mobile (formerly Intelligent Information
Incorporated) and NBC Interactive Media, Inc. (the "Letter Agreement"), and
where otherwise applicable, i3 Mobile will make an aggregate of five percent
(5%) of its unused inventory of wireless advertising taglines available to MSNBC
Interactive (a copy of the letter is attached hereto as Appendix A and made a
part hereof). The value of this inventory for purpose of this Agreement shall be
calculated at the i3 Mobile's rate card for run of service taglines in effect at
the time such taglines are ordered. The taglines shall promote the products and
services of MSNBC Interactive and its affiliates, and may not advertise, promote
or mention any other product, service, web site or third party whatsoever
without the prior written consent of i3 Mobile. In addition, with respect to the
placement or delivery of such taglines on any particular wireless network, i3
Mobile may reject such taglines if they would compete with or violate the rights
of any other advertiser, sponsor or i3 Mobile distribution partner, as
determined by i3 Mobile in its sole discretion and in good faith.

(g)     Review by MSNBC Interactive. i3 Mobile shall provide MSNBC Interactive
with reasonable access to i3 Mobile's technology and systems for distribution of

<PAGE>   3

permitted and as technically feasible the number of Users that elect to receive
Headlines, the percentage of all eligible Users that elect to receive Headlines,
the number of Users that receive Headlines for free versus on a subscription
basis, the names and e-mail addresses of Users who elect to receive Headlines,
and any other usable data or information that is reasonably requested by MSNBC
Interactive (the "User Data"). All User Data shall be provided on both an
aggregate basis and broken down by Designated Reseller. Such User Data shall be
delivered to MSNBC Interactive via e-mail or FTP in a machine-readable format as
reasonably specified by MSNBC Interactive. MSNBC Interactive may use the User
Data for its own internal purposes, and may sell, distribute or share such User
Data with its affiliates and partners; provided, that MSNBC Interactive shall be
required to comply with the privacy policy of each applicable Designated
Reseller. Neither i3 Mobile nor any Designated Reseller may license, sell,
distribute or share such User Data with third parties unless such User Data is
(i) aggregated with data collected with respect to other Content Providers, it
being understood that the User Data collected hereunder shall never constitute a
majority of any aggregated pool of data licensed, sold, distributed or shared by
i3 Mobile or any Designated Reseller, and (ii) in no way traceable to or
identifiable as information of, or directly related to, MSNBC Interactive or its
affiliates.

4.      OBLIGATIONS OF MSNBC INTERACTIVE. Subject to the terms and conditions
of this Agreement, MSNBC Interactive shall provide at least four (4) Headlines
per day to i3 Mobile, with two (2) Headlines being made available by 9:30 a.m.
Eastern time and two (2) headlines being made available at 4:00 Eastern time.
The Headlines shall be made available to i3 Mobile via e-mail or other mutually
agreed upon electronic means. MSNBC Interactive shall use commercially
reasonable efforts to maintain the timeliness of the Content; provided, that i3
Mobile acknowledges that, in part, MSNBC Interactive relies on the performance
of Content Providers and technology providers outside the control of MSNBC
Interactive in order to provide the Headlines.

5.      MARKETING

        (a) Expenses. i3 Mobile shall be responsible for all expenses incurred
by i3 Mobile in promoting and marketing the Headlines, unless such expenses have
been agreed to be paid by MSNBC Interactive or a third party advertiser in
writing in advance.

        (b) Use of Trademarks. i3 Mobile acknowledges that MSNBC Interactive's
trademarks are the sole and exclusive property of MSNBC Interactive. i3 Mobile
shall use its best efforts to name MSNBC Interactive as one of its premier
information services in its formal promotional and marketing materials relating
to the Designated Resellers services. MSNBC Interactive agrees that i3 Mobile
has the right to use the MSNBC Interactive Trademarks set forth on Appendix B to
this Agreement in its own marketing and advertising materials, subject to the
terms of this Agreement and with the prior written approval of MSNBC
Interactive, such approval not to be unreasonably withheld.

        (c) Prior Approval. i3 Mobile agrees to submit to MSNBC Interactive for
prior written approval all press releases, advertising or other promotional
materials that reference the Headline services or use MSNBC Interactive's
company name or trademarks not less than fifteen (15) days before the proposed
use. MSNBC Interactive shall not unreasonably withhold its approval. Unless
notice of approval or disapproval is received within (10) days of receipt of
promotional materials, approval shall be deemed granted. i3 Mobile shall be
solely responsible for insuring that Designated Resellers and Users use the
trademark solely in such form as has been previously approved by MSNBC
Interactive.

6.      EDITORIAL CONTROL. MSNBC Interactive shall retain sole editorial
control  over the content and presentation of the Headlines; provided, that i3
Mobile may make changes to the formatting of the Headlines, subject to
consultation with MSNBC Interactive, in order to meet wireless display
equipment formats. i3 Mobile shall not edit, abridge, rewrite or in any way
alter the Headlines, or create any work derived from the Headlines, without the
prior written consent of MSNBC Interactive.

7.      PROPERTY AND PROPRIETARY RIGHTS. All rights in and to any and all
Content furnished by MSNBC Interactive or any of its Affiliates in connection
with this Agreement, including without limitation the Headlines, shall remain in
MSNBC Interactive or such Affiliate, as the case may be, and no right, title or
interest in or to any of the same is granted, transferred or assigned to i3
Mobile by this Agreement.

8.      PAYMENT.  Neither party shall be required to pay in fees to the other
party in connection with the services contemplated by this Agreement.

        (a)     Term. This term of this Agreement shall commence on the
Effective Date and shall remain in effect for an Initial Term of two (2) years.

disclosed generally to third parties by the disclosing party without
restrictions similar to those contained in this Agreement, or (vii) is disclosed
pursuant to the order or requirement of a court, administrative agency, or other
governmental body; provided, that the receiving party shall provide prompt

party may disclose the terms and conditions of this Agreement (A) as required by
any court or other governmental body, (B) as otherwise required by law, (C) to
legal counsel of the parties, (D) in confidence, to accountants, banks and
financing sources and their respective advisors, (E) if necessary in connection
with the enforcement of this Agreement or rights under this Agreement, or (F) in
confidence, in connection with an actual or proposed merger, acquisition or
similar transaction.

16.     MISCELLANEOUS.

(a)     Binding Nature and Assignment. This Agreement shall be binding on the
parties hereto and their respective successors and assigns, but neither party
may assign this Agreement without the prior written consent of the other, such
consent not to be unreasonably withheld; provided, however, that this Agreement
may be assigned by MSNBC Interactive to a direct or indirect parent, subsidiary
or affiliate without consent of i3 Mobile.

(b)     Compliance with Law. Each party shall comply with all applicable laws,
codes, ordinances, rules and regulations of the federal, state and local
governments, and of any and all political subdivisions and regulatory
authorities thereof. Each party shall obtain all necessary permits and licenses
required in connection with the performance of it obligations hereunder.

(c)     Notices. Any notice required or permitted by this Agreement shall be in
writing and shall be deemed sufficient upon receipt, when delivered personally
or by courier or overnight delivery service, or forty-eight (48) hours after
being deposited in the regular mail as certified or registered mail with postage
prepaid, if such notice is addressed to the party to be notified at such party's
address as set forth in the preamble of this Agreement. Either party hereto may
from time to time change its address for notification purposes by giving the
other prior written notice of the new address and the date upon which it will
become effective.

(d)     Headings.  The article and section headings used herein are for
reference and convenience only and shall not enter into the interpretation
hereof.

(e)     Relationship of Parties. i3 Mobile, in furnishing services to MSNBC
Interactive hereunder, is acting only as an independent contractor and assumes
full responsibilities for each of its employees and shall be solely responsible
for the payment of compensation to its personnel. This Agreement does not
constitute either party as the agent or legal representative of the other party
and does not create a partnership or joint venture between them.

(f)     Severability. If any provision of this Agreement is declared or found
to be illegal, unenforceable or void, then both parties shall be relieved of
all obligations arising under such provision, but only to the extent that such
provision is illegal, unenforceable or void, it being the intent and agreement
of the parties that this Agreement shall be deemed amended by modifying such
provision to the extent necessary to make it legal and enforceable while
preserving its intent or, if that is not possible, by substituting therefor
another provision that is legal and enforceable and achieves the same
objective. If the remainder of this Agreement shall not be affected by such
declaration or finding and is capable of substantial performance, then, each
provision not so affected shall be enforced to the extent permitted by law.

(g)     Press Releases. Except to the extent required by applicable law or as
otherwise specified herein, any use by one party of the other party's name,
trademarks or service marks in any press releases, customer lists, marketing
materials or other announcements concerning the matters covered by this
Agreement, or for promotional, advertising or other purposes, shall require the
other party's prior written approval; provided, that MSNBC Interactive shall
have the right to

<PAGE>   8

approve any description of MSNBC Interactive and the transactions contemplated
by this Agreement which are included in any documents filed by i3 Mobile with
the Securities and Exchange Commission, such approval not to be unreasonably
withheld.

(h)     Waivers. No delay or omission by either party hereto to exercise any
right or power hereunder shall impair such right or power or be construed to be
a waiver thereof. A waiver by either of the parties hereto of any of the
covenants to be performed by the other or any breach thereof shall not be
construed to be a waiver of any succeeding breach thereof or of any other
covenant herein contained. All remedies provided for in this Agreement shall be
cumulative and in addition to and not in lieu of any other remedies available to
either party at law, in equity or otherwise.

(i)     Force Majeure. If the performance of this Agreement or any obligation
hereunder is prevented, restricted or interfered with by reason of fire or other
casualty or accident, acts of God, severe weather conditions, war or other
violence, any law, order, proclamation, regulation, ordinance, demand or
requirement of any governmental agency, or any other act or condition beyond the
reasonable control of the parties hereto, the party whose performance is so
affected shall be excused from such performance; provided, that if either party
invokes this Section for any consecutive period of thirty (30) days or longer,
then the other party may immediately terminate this Agreement without penalty,
upon written notice to such invoking party.

(j)     Survival of Terms. Termination or expiration of this Agreement for any
reason shall not terminate any rights, liabilities or obligations that have
either accrued prior to the effective date of termination of this Agreement or
which the parties have expressly agreed shall survive any such termination or
expiration.

(k)     Entire Agreement. This Agreement constitutes the entire agreement
between the parties hereto with respect to the subject matter hereof, and there
are no written or oral representations, understandings or agreements relative
hereto which are not fully expressed herein. This Agreement is intended to be
the sole and exclusive statement of the agreement between the parties hereto
with respect to the subject matter hereof and any other terms or conditions
included in any forms utilized or exchanged by the parties hereto shall be of no
force or effect and shall not be incorporated herein or be binding unless
expressly agreed to in writing by both parties hereto. No change, amendment,
waiver or discharge hereof shall be valid unless in writing and signed by an
authorized representative of the party against which such change, amendment,
waiver or discharge is sought to be enforced.

(l)     Governing Law; Jurisdiction. This Agreement and all acts and
transactions pursuant hereto and the rights and obligations of the parties
hereto shall be governed, construed and interpreted in accordance with the laws
of the State of New York, without giving effect to principles of conflicts of
law. Each of the parties to this Agreement consents to the exclusive
jurisdiction and venue of the state and federal courts of New York County, New
York. In any action or suit to enforce any right or remedy under this Agreement
or to interpret any provision of this Agreement, the prevailing party shall be
entitled to recover its costs, including reasonable attorneys' fees.

(m)     Counterparts.  This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original and all of which
together shall constitute one instrument.

Mr. Steve Maloney
President & CEO
Intelligent Information Incorporated
181 Harbor Drive, 3rd Fl.
Stamford, CT  06902

Dear Steve:

As you know, we at NBC Interactive Media ("NBC") are excited about working with
Intelligent Information Incorporated ("III") regarding a wireless distribution
deal for certain of our interactive properties. Pending the execution of one or
more definitive distribution agreements (each, a "Distribution Agreement") and
certain other documentation as more fully described below, this letter agreement
will confirm our discussions regarding our relationship as follows:

1.      Distribution. (a) III shall make wireless distribution services
available to NBC and its affiliates (including, for example, NBC Internet, Inc.,
MSNBC Interactive News LLC and CNBC.com LLC) (each, an "NBC Entity") for use in
connection with their interactive content offerings. III shall provide each NBC
Entity with a Distribution Agreement with terms and conditions, including
marketing fee allocations and distribution and performance metrics, no less
favorable to such NBC Entity than those provided to any other customer of III
contracting for a similar volume of services.

        (b)     Following execution of any Distribution Agreement, to the
extent III offers a lower price or a more favorable marketing fee allocation
to any customer contracting for a similar volume of services, such lower price
shall automatically be applied on a going forward basis to each of the
Distribution Agreements. At any time during the term of the Distribution
Agreements, an NBC Entity may request, and III shall promptly provide, an
officer's certificate certifying that III has been and remains in compliance
with this Section.

2.      Preferred Placement: Each Distribution Agreement shall provide, to the
extent technically feasible within the III wireless services, Preferred
Placement (as defined below) for NBC's interactive properties and affiliates
with respect to the type of content distributed pursuant to such Distribution
Agreement (for example, a Distribution Agreement for MSNBC.com would provide
Preferred Placement for MSNBC in the news category); provided that III shall not
be

<PAGE>   11

required to provide such Preferred Placement if exclusivity or Preferred
Placement for such type of content has been provided, prior to the execution of
the Distribution Agreement, to a third party not affiliated with III. Preferred
Placement shall mean (a) where a link to or display of content appears on a
list, such link or content is in the default, top-most and left-most position;
or (b) when a link to or display or content appears in a format other than a
list, the link or content is more visually prominent, or at a higher rate of
exposure, than other content partners.

3.      Promotion: (a) III will make five percent (5%) of its unused inventory
of wireless advertising taglines available to the interactive properties of the
NBC Entities following execution of any Distribution Agreement; provided that if
more than one NBC Entity enters into a Distribution Agreement, the first two NBC
Entities that enter into Distribution Agreements with III shall allocate such
unused inventory equally between them. The value of this inventory for purpose
of this Agreement shall be calculated at the III rate card for run of service
taglines in effect at the time such taglines are ordered.

        (b)     The taglines shall promote the products and services of NBC and
its affiliates, and may not advertise, promote or mention any other product,
service, web site or third party whatsoever without the prior written consent of
III. In addition, with respect to the placement or delivery of such taglines on
any particular wireless network, III may reject such taglines if they would
compete with or violate the rights of any other advertiser, sponsor or III
distribution partner, as determined by III in its sole discretion and in good
faith.

        (c)     III will provide marketing funds at a mutually agreed upon
level to NBC and the NBC Entities in support of the joint wireless initiatives
of III and the NBC Entities, but in no event shall the amount of marketing
funds provided to NBC and the NBC Entities be less than the value of the
advertising taglines provided to NBC and the NBC Entities. These funds will be
used in support of marketing activities at the discretion of the parties.

4.      Warrants. (a) Upon execution of each Distribution Agreement by III and
NBC Entity, III will grant to NBC for distribution to itself or, pursuant to
NBC's instructions, in whole or in part, to such NBC Entity, a fully-vested
warrant (each, a "Warrant") to purchase up to 20,000 shares of III's Common
Stock at an exercise price equal to $10.00 per share. In the event the first
Distribution Agreement is executed on or before March 31, 2000, the Warrant
granted in consideration therefore shall be for 30,000 shares (the "Bonus
Shares"). The aggregate number of shares available hereunder, including the
Bonus Shares, shall not exceed 110,000 shares. NBC shall use its commercially
reasonable efforts to cause the NBC Entities to enter into Distribution
Agreements with III.

        (b)  Each Warrant shall expire three (3) years following its issuance
and shall not terminate upon an initial public offering or change of control of
III. Subject to any relevant securities laws, rules and regulations, each
Warrant, as well as the equity acquired through exercise thereof, will be freely
transferable by NBC or such NBC Entity and may be exercised in whole or in part.
When exercising any Warrant, NBC or such NBC Entity shall have the right to
either (i) purchase the total number of shares of equity which such Warrant
entitles NBC or such NBC Entity to purchase at the exercise price described
above or (ii) receive the net number of shares of equity arising from the
difference between the market price of such equity at the date of exercise and
the exercise price for the Warrant.

5.      Public Relations. Each party will issue a press release announcing the
relationship between the parties, with each such press release subject to the
approval of the other party. NBC will provide a reasonable level of public
relations resources to promote the strategic alliance between of III and NBC.

6.      Term. The term of this Letter Agreement shall be two (2) years and,
during such period, each NBC Entity shall have the right to enter into a
Distribution Agreement with a term of up to three (3) years, with each such term
commencing upon the execution of each such Distribution Agreement.

                                            Sincerely,

                                            NBC Interactive Media, Inc.

                                            Margaret T. Murphy
                                            Vice President

Acknowledged and agreed:

Intelligent Information Incorporated
