Licensee and their respective Controlled Related Parties (each a "Restricted
Party"), shall cause their respective officers and directors (in their capacity
as such) to, and shall take all reasonable measures to cause their respective
employees, attorneys, accountants, consultants and other agents and advisors
(collectively, and together with their respective officers and directors,
"Agents") to, keep secret and maintain in confidence the terms of this agreement
and all confidential and proprietary information and data of the other party or
its Related Parties disclosed to it (in each case, a "Receiving Party") in
connection with the performance of its obligations under this agreement (the
"Confidential Information") and shall not, and shall cause their respective
officers and directors not to, and shall take all reasonable measures to cause
their respective other Agents not to, disclose Confidential Information to any
Person other than the parties, their Controlled Related Parties and their
respective Agents that need to know such Confidential Information. Each party

purpose other than determining and performing its obligations and exercising its
rights under this agreement. Each party shall take all reasonable measures
necessary to prevent any unauthorized disclosure of the Confidential Information
by any of their respective Controlled Related Parties or any of their respective
Agents.  The measures taken by a Restricted Party to protect Confidential
Information shall be not deemed unreasonable if the measures taken are at least
as strong as the measures taken by the disclosing party to protect such

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

           party;

     (ii)  prior to receipt hereunder was property within the legitimate
           possession of the Receiving Party or, subsequent to receipt hereunder
           is lawfully received from a third party having rights therein without
           restriction of the third party's right to disseminate the
           Confidential Information and without notice of any restriction
           against its further disclosure;

     (iii) is independently developed by the Receiving Party through Persons who
           have not had, either directly or indirectly, access to or knowledge
           of such Confidential Information;

     (iv)  is disclosed to a third party with the written approval of the party
           originally disclosing such information, provided that such

           Confidential Information shall cease to be confidential and
           proprietary information covered by this agreement only to the extent
           of the disclosure so consented to;

           is required to be produced under order of a court of competent
           jurisdiction or other similar requirements of a governmental agency,
           provided that such Confidential Information to the extent covered by
           --------
           a protective order or its equivalent shall otherwise continue to be
           Confidential Information required to be held confidential for purpose

           its Related Party) are listed.

     Section 3.3.   Financial Institutions.  Notwithstanding this Article 3, any
                    ----------------------
party may provide Confidential Information to any financial institution in
connection with borrowings from such financial institution by such party or any
of its Controlled Related Parties, so long as prior to any such disclosure such
financial institution executes a confidentiality agreement that provides
protection substantially equivalent to the protection provided the parties in
this Article 3.

     Section 3.4.   Procedures.  In the event that any Receiving Party (i) must
                    ----------
disclose Confidential Information in order to comply with applicable Law or the
requirements of a stock exchange or association on which such Receiving Party's
securities or those of its Related Parties are listed or (ii) becomes legally
compelled (by oral questions, interrogatories, requests for information or
documents, subpoenas, civil investigative demand or otherwise) to disclose any
Confidential Information, the Receiving Party shall provide the disclosing party
with prompt written notice so that in the case of clause (i), the disclosing
party can work with the Receiving Party to limit the disclosure to the greatest
extent possible consistent with legal obligations or in the case of clause (ii),
the disclosing party may seek a protective order or other appropriate remedy or
waive compliance with the provisions of this agreement.  In the case of a clause
(ii), (A) if the disclosing party is unable to obtain a protective order or
other appropriate remedy, or if the disclosing party so directs, the Receiving
Party shall, and shall cause its employees to, exercise all commercially
reasonable efforts to obtain a protective order or other appropriate remedy at
the disclosing party's reasonable expense, and (B) failing the entry of a
protective order or other appropriate remedy or receipt of a waiver hereunder,
the Receiving Party shall furnish only that portion of the Confidential
Information which it is advised by opinion of its counsel is legally required to
be furnished and shall exercise all commercially reasonable efforts to obtain
reliable assurance that confidential treatment shall be accorded such
Confidential

cost and expense of the disclosing party whose Confidential Information has been
sought.

          with, violate or result in a breach of any of the terms, conditions or
          provisions of any law, regulation, order, writ, injunction, decree,
          determination or award of any court, any governmental department,
          board, agency or instrumentality, domestic or foreign, or any

          violation, breach or default that has been validly and unconditionally
          waived), (iii) will conflict with, violate, result in a breach of,
          constitute a default under (whether with notice or lapse of time or

          material properties or assets of such party or any of its Controlled
          Related Parties, which in any such case could reasonably be expected
          to materially impair such party's ability to perform its obligations
          under this agreement or to have a material adverse effect on the
          consolidated financial condition of each party or its Parent.

          expected to materially impair such party's ability to perform its
          obligations under this agreement or to have a material adverse effect
          on the consolidated financial condition of such party or its parent;

          positioning. Pre-production advertising/communications will be
          reviewed by Sprint for consistency with the Sprint Brand Positioning

                          SPONSORSHIP AND ENDORSEMENT
                      SELECTION GUIDELINES AND STANDARDS

I.   SPONSORSHIPS

The following guidelines are used when determining whether or not Sprint will
invest in a particular sponsorship property.

 .    The sponsorship must be consistent with the overall positioning of the
     Sprint brand, and must be consistent with Sprint's sponsorship
     marketing objectives of brand building, business building, and positive
     employee impact.

 .    The sponsorship must reflect or enhance Sprint's position or image in
     the marketplace. There must be a natural telecommunication link with
     the property, preferably as the/a provider.

 .    The sponsorship should be a legitimate forum for Sprint's participation.

 .    The sponsorship should offer a dominant position among sponsors of the
     property/event and/or should provide category exclusivity. This brand
     visibility for Sprint should occur through on-site signage, the event
     name and media visibility, as examples.

 .    The sponsorship should provide an opportunity for a consistent, long-term
     relationship with the property.

 .    If the sponsorship is a barter deal, the media/merchandising value of
     the sponsorship should reflect a 2.5x or greater return for Sprint
     vis-a-vis the barter amount.

 .    The sponsorship must provide opportunities for measurement such that
     both brand impact and business impact can be quantified.

II.  ENDORSEMENTS

 .    Endorsements of the Sprint brand should be used in a manner consistent
     with Sprint's brand positioning and personality. New endorsements
     should in no way compete with existing programs.

 .    Sprint will review any new endorsements that are being recommended and
     will make judgments on consistency and conflict within fourteen (14)
     days of receipt.

Use of Celebrity and/or Public Figures
--------------------------------------

 .    The use of a celebrity/public figure must be consistent with Sprint's
     brand positioning and enhance Sprint's brand personality.

 .    Use of new celebrities/public figure should not be in conflict with
     current celebrity programs, and should not be considered if such use
     would serve to confuse customers. Sprint currently has a primary
     celebrity spokesperson, Candice Bergen. Any additional celebrities must
     complement - not serve as a substitute for - Candice Bergen as
     spokesperson.

 .    The celebrity should offer telecommunications category (worldwide) and
     cable MSO exclusive rights to Sprint.

 .    Celebrities/public figures who have now, or in the past, a
     controversial role (as determined by Sprint) should not be considered.

 .    Measurement data should be provided to confirm the celebrities broad-based
     appeal.

                          SPRINT GUIDELINES/STANDARDS

Standards and Monitor Process
-----------------------------

The Sprint brand is critical to the short-term and long-term success of Sprint.
As such, it is extremely important that we protect the brand by displaying it in
a manner that is appropriate for family viewing. As a marketer and advertiser
our objective is to communicate the value of the products and services we offer
                    -----------
to consumers. Unless negotiated as part of a sponsorship contract, we do not
consider Sprint a "sponsor" of any program in which we advertise or product on
which the Sprint Marks appear. The program, Internet site or product is simply a
vehicle for communication to our targeted consumers.

General Guidelines
------------------

1.   Use the Marks only in a manner that will continue to build positive
     consumer perceptions toward the Sprint brand.

2.   Although we can not dictate positioning on television or Internet
     advertising during specific editorial, news related advertising should not
     be positioned near "Special Reports" due to tragic events or disasters
     (i.e. Oklahoma City bombings, O.J. Simpson trial, etc.)

3.   Do not advertise on television or Internet sites that are overly
     controversial, significantly biased, or presented in a manner that would be
     considered offensive to the general public.

4.   Use of the Sprint Marks with third parties or on retail packaging is
     prohibited unless authorized by the License Agreement. If the Sprint Marks
     are used with a third party's marks or on retail packaging pursuant to the
     License, the Use of the Sprint Marks must not be offensive, must not make
     any false or unethical claims and must not imply a relationship between
     Sprint and a telecommunications company not affiliated with Sprint.

Content to Avoid on Television or Internet or in Third Party Use
----------------------------------------------------------------

1.   Excessive vulgar language, violence, or sexual conduct that is explicit and
     would not be considered appropriate for family viewing.

2.   Discriminating or inflammatory representation or editorial content which is
     specific to a particular individual, group, religious or political
     affiliation, ethic background, or gender.
<PAGE>

3.   News programming that represents or expresses a bias relative to
     controversial political or social issues.

4.   Content, editorial, or investigative reporting that creates a negative
     perception of the telecommunications industry.

General Definitions
-------------------

The issue of determining appropriate content is very subjective and will vary
from individual to individual. The following definitions will provide direction
for key content issues.

Violence - Gratuitous, on-screen, violent acts that have significant
re-occurrence during an episode or movie are not appropriate for Sprint
advertising.

Nudity - Programming or Internet sites that contain strong sexual content and/or
nudity is not acceptable for Sprint programming. However, if the scene is
important to the plot and is not the primary theme of the episode or movie, it
is acceptable only with advertising positioning away from the scene in question.

Language - The excessive use of vulgar language is not appropriate.

News Programming - News specific programs or Internet sites are acceptable when
the journalism is handled in a professional and unbiased manner. (i.e. early or
late local news, network news, CNN Headline news, CNN.com, etc.)

News magazines are considered an appropriate advertising vehicle. However,
individual episodes in which Sprint advertises must be prescreened to determine
sensitivity to the particular topics being addressed. Any segment which contains
a highly controversial topic that may negatively impact consumer perceptions of
Sprint must be avoided.

Television Program Monitoring Process
-------------------------------------

All prime-time television programming that is scheduled to include Sprint
advertising is pre-screened to determine if the content is appropriate for
Sprint. The following is the procedure for content monitoring to ensure that the
guidelines are met and the Sprint brand is protected:

 .    Provide the content screening company with Sprint's schedule of prime-time
     programming including up to the minute changes.

 .    All Sprint programming is screened to determine if the content is
     appropriate for Sprint (per our guidelines).

 .    Agency network buying group is notified immediately of any content
     concerns.
<PAGE>

 .    Agency contacts Sprint Brand Investment Group Media staff regarding the
     content in question. Sprint will make final decision regarding the
     acceptability of the programming.
