                           LICENSING SUPPORT AGREEMENT

This Licensing Support Agreement (the "Agreement") is effective April 21, 2003
("Effective Date") between BellSouth Intellectual Property Marketing Corporation
("BIPMARK"), a Georgia corporation having an office at 1155 Peachtree Street,
Suite 500, Atlanta, GA 30309 and Cingular Wireless, LLC ("CINGULAR"), a Delaware
Limited Liability Corporation having an office at Glenridge Highlands Two, 5565
Glenridge Connector, Atlanta, GA 30342.

                                    PREAMBLE

BellSouth Intellectual Property Corporation ("BIPCO") owns certain rights in and
to intellectual property, including United States and foreign patents,
copyrights and know-how and technology embodying such intellectual property
(collectively, "Intellectual Property" or "BIPMARK Intellectual Property") and
BIPMARK has the exclusive right to license the same to third parties;

CINGULAR owns certain rights in and to intellectual property, including patent
applications, copyrights, and know-how and technology embodying such
intellectual property (collectively Intellectual Property or Cingular
Intellectual Property) and CINGULAR has the exclusive right to license the same
to third parties;

Each Party has technical and business expertise that may be useful to the other
Party in licensing its intellectual property to third parties.

THEREFORE, in consideration of the foregoing premises and of the terms and of
the terms and conditions of this Agreement, and other good and valuable
consideration, the receipt and sufficiency of which the Parties hereby
acknowledge, the Parties agree as follows:

1.       DEFINITIONS

"Affiliates" means any company owned by, owning, or under common ownership with,
in whole or in part, now or in the future, directly or indirectly through a
subsidiary or by virtue of a common parent corporation, a Party hereto.
Affiliates shall include BellSouth International, Inc., ("BellSouth
International") but shall not include any properties owned by BellSouth
International unless such properties are 100% owned by BellSouth International.

1.2      "Intellectual Property" means the patents, patent applications,
technology, copyrights, trade secrets, and trademarks owned by the respective
Parties.

1.3      "Third Party License" means a license of a Party's Intellectual
Property to a party other than CINGULAR, BIPMARK, or their Affiliates.

2.       DUTIES OF PARTIES

2.1      Either Party (as "Requesting Party"), from time to time, may request
the assistance of the other Party (as "Assisting Party") in supporting its
respective Intellectual Property licensing efforts. Such assistance may include,
but is not limited to, identifying patents and technology with licensing
potential, identifying target licensees and their relevant products and
services, investigating target licensees' products and services for infringement
of the patents (including reverse engineering, if necessary), and providing
support during negotiations and litigation with target licensees. Such
assistance may be provided by a Party, an Affiliate, or agents or subcontractors
thereto, as appropriate.

Each request by the Requesting Party shall be in writing and shall include
information identifying the relevant Intellectual Property, the type and extent
of work to be done by the Assisting Party, the target date of completion,

                                                                   EXHIBIT 10.53

the anticipated level and scope of technical support, and the proposed revenue
share (in percentage or dollars) for the Assisting Party (the "Request").

         (a) The Assisting Party shall have the sole right to accept or reject
         the Request. Acceptance of a Request shall occur when the Requesting
         Party receives a signed copy of the Request from the Assisting Party
         via facsimile, U.S. mail, or via email with the signature block
         completed in an appropriate manner. Digital signatures shall not be
         required for email communications, provided such emails originate from
         a person of apparent authority to bind the Party.

         (b) Such Acceptance shall include, as applicable, the percentage of
         revenue shared, levels of the personnel who will perform the work, an
         estimate of the number of man-hours required by Assisting Party to
         complete the work identified in the Request, and/or the hourly rate the
         Assisting Party will charge the Requesting Party for the work, if
         different than the default hourly rate set forth in section 3.2. Any
         Request that has not been accepted by the Assisting Party within two
         (2) weeks of receipt shall be deemed to be rejected. If the Assisting
         Party determines that more information is required by the Assisting
         Party in order to respond to said Request, the Assisting Party shall
         notify the Requesting Party as to the additional information necessary
         to determine whether to accept or reject the Request. The Assisting
         Party will have two (2) weeks from receipt of additional information to
         submit an Acceptance, if so desired.

         (c) The Requesting Party shall have the sole right to confirm or reject
         the Acceptance, based on the information provided by the Assisting
         Party in the Acceptance. Confirmation of an Acceptance shall occur when
         the Assisting Party receives a signed copy of the Acceptance from the
         Requesting Party via facsimile, U.S. mail, or via email (subject to the
         conditions set forth above) with the signature block completed in an
         appropriate manner. Any Acceptance that has not been confirmed by the
         Requesting Party within one (1) week shall be deemed to be rejected.

2.4      Each Request, Acceptance, and Confirmation shall be in a form
substantially the same as that shown in Exhibit A and shall reference this
Agreement. To the extent that the terms of a Request and the terms of the
Acceptance conflict (and the Acceptance has been rejected by the Requesting
Party), the Parties shall negotiate in good faith to attempt to arrive at
mutually acceptable terms. If the Parties agree to mutually acceptable terms,
the Requesting Party shall resubmit the Request and the Assisting Party shall
resubmit the Acceptance, as appropriate, including the mutually acceptable
terms. To the extent that the terms of the Request and Acceptance conflict with
any terms in this Agreement, the terms of the Request and Acceptance shall
control.

2.5      Either Party may provide licensing intelligence or other leads by
contacting the other Party with specific information that identifies a
particular incentive/ "carrot" or compulsory/ "stick" licensing opportunity
related to the other Party's Intellectual Property ("Licensing Lead"). The Party
that receives the Licensing Lead has the sole discretion to determine whether to
pursue such lead, and if so, the Party that receives the Licensing Lead may
issue a Request to the Party that identified the lead. If the Party receiving
the Licensing Lead decides not to pursue such lead and decides not to issue a
Request, or if the Party receiving the lead was already aware of the
intelligence or information that was the subject of the Licensing Lead
("Licensing Lead Awareness) and decides not to issue a Request, then the Party
providing the Licensing Lead shall not be entitled to compensation for providing
the Licensing Lead, except for a reasonable hourly fee as set forth in section
3.2, not to exceed 5 man-hours per lead. However, if the Party receiving the
Licensing Lead did not have Licensing Lead Awareness and uses the lead to enter
into a Third Party License without issuing a Request for assistance from the
Party providing the Licensing Lead, then the Party providing the Licensing Lead
shall be entitled to compensation in accordance with section 3.1. The Party
receiving the Licensing Lead may attempt to inform the Party providing the lead
if it decides not to pursue such lead or if it is already aware of the
intelligence or information included in the lead. The Parties acknowledge that
there that there is no standard definition for Licensing Lead and Licensing Lead
Awareness that adequately describes the range of circumstances surrounding that
lead. Accordingly, in determining Licensing Leads and Licensing Lead Awareness,
it is not sufficient to generally know the potential for licensing intellectual
property or technology to a third party, but rather more specific knowledge is
required, and the following factors should be considered: (1) knowledge of the
target licensee; (2) knowledge of contact personnel within target licensee; (3)
whether contact with Licensee has been established; (4) knowledge of specific
project or product which is subject to license; (5) knowledge of rollout of
future product or service which is subject to license; (6) knowledge of reverse

                                                                   EXHIBIT 10.53

engineering results; (7) knowledge of specific need or RFP for acquisition of
technology (as opposed to a pure patent license); (8) knowledge of licensing
parameters acceptable to Licensee.

2.6      The Assisting Party shall provide the appropriate personnel and
allocate the appropriate resources to provide the assistance requested by the
Requesting Party in a timely manner. The Requesting Party shall be given access
to the appropriate personnel and facilities of the Assisting Party in a
sufficient manner to allow the Requesting Party to obtain pertinent information
from personnel of the Assisting Party as specified in the Request.

2.7      All costs and expenses associated with the efforts of each Party under
this Agreement shall be borne by the Party that incurred the respective costs
and expenses, unless otherwise agreed to by the Parties in advance. Each Party
acknowledges that the Party that owns the Intellectual Property to be licensed
has the sole right to determine whether or not to enter into any Third Party
License of their own intellectual property. For licensing negotiations in which
both Parties have Intellectual Property to be licensed, the Party that owns the
majority of the intellectual property shall have the right to control and lead
the negotiations, unless otherwise agreed to by the Parties, yet both Parties
must agree to enter into such Third Party License. For licensing scenarios in
which both Parties have Intellectual Property to be licensed, and where
reasonable efforts have been made to jointly license the intellectual property
of both Parties prove unsuccessful, each individual Party retains the right to
enter into a separate agreement to license its own intellectual property.

2.9      Neither Party shall have the right to license or market the other
Party's Intellectual Property or contact any potential licensee relating to
licensing the other Party's Intellectual Property without the prior written
consent of the Party that owns the Intellectual Property. However, the Parties
acknowledge that through the ordinary course of business, each Party may be in
contact with third parties for reasons unrelated to the licensing of
Intellectual Property and that opportunities for licensing the other Party's
Intellectual Property to such third parties may ultimately arise from such
contact. This circumstance will not violate the prohibition on licensing and
marketing the other Party's Intellectual Property set forth in this section so
long as the Party promptly informs the other Party of the licensing opportunity
and allows the other Party to control and lead the negotiations in accordance
with this Agreement.

2.10     Each Party shall have the right, but not the obligation, to enforce
rights in its own intellectual property relating to this Agreement. If a Party
("Enforcing Party") decides to enforce its intellectual property rights
hereunder ("Enforcement Action"), the other Party ("Cooperating Party") shall
use good faith commercial efforts to cooperate with the Enforcing Party at the
request and reasonable expense of the Enforcing Party. Good faith commercial
efforts in this context shall mean that the Cooperating Party shall reasonably
cooperate with the Enforcing Party unless, in the sole discretion of the
Cooperating Party, that such reasonable cooperation is not in its best
commercial interest. Either Party may request that the Parties cooperate more
fully than that contemplated above by having the Cooperating Party actively
participate in, or become a party to, an Enforcement Action. If the Parties
agree in such a case to more actively cooperate, the Enforcing Party and the
Cooperating Party shall negotiate in good faith an agreement ("Enforcement
Agreement") allocating risks, rights, responsibilities, cost, recovery and any
other material matters relating to the Enforcement Action. Such an Enforcement
Agreement shall also determine whether, as a reward for sharing the risk of
participation in the Enforcement Action, the Cooperating Party shall be entitled
to a greater share of future licensing revenue than it would be entitled to
absent an Enforcement Action. In the event that an Enforcement Action involves
both Parties' intellectual property rights, then prior to initiating such an
Enforcement Action, the Parties shall enter into an Enforcement Agreement.

3.       PAYMENT

3.1      For each Acceptance that has been confirmed by the Requesting Party,
the Requesting Party shall pay to the Assisting Party the greater of: (a)
twenty-five percent (25%) of all license fees and royalties that the Requesting
Party (as the "Licensing Party") collects pursuant to all Third Party Licenses
for which the Assisting Party provided assistance pursuant to the Acceptance of
the Request ("Shared Revenue Payment"); or (b) an hourly fee based on the amount
of man-hours estimated and worked by the Assisting Party pursuant to the
Acceptance of the Request.

3.2      The Assisting Party, at the time of or prior to the Acceptance, can
request in writing to be paid the hourly fee as specified in section 3.1(b). The
hourly fee for such man-hours may be agreed to by the Parties and specified in

the Acceptance, but the default hourly fee in the absence of an agreement by the
Parties is one hundred fifty dollars ($150.00) per hour. Upon requesting to be
paid an hourly fee pursuant to this section, or upon a determination that the
hourly fee of section 3.1(b) is greater than the Shared Revenue Payment of
section 3.1(a), the Assisting Party shall provide an invoice to the Requesting
Party with a reasonably detailed description of the number of hours worked by
each person and the tasks performed by each person pursuant to the Request.
Payment of such hourly fees shall be made only upon completion of the work
pursuant to an accepted Request, and shall be made within sixty (60) days of the
invoice date. If the Assisting Party is paid an hourly fee, unless otherwise
agreed, it shall not be entitled to receive any Shared Revenue Payment in the
event a Third Party License is subsequently entered into.

If agreed to, either in a Request, Acceptance, or in another writing signed by
both Parties, the Shared Revenue Payment referenced in section 3.1(a) may be
increased up to one hundred percent (100%) or decreased to zero percent (0%) of
the license fees and royalties collected by the Licensing Party pursuant to a
Third Party License. Such increase or decrease may be based on factors such as
the amount, quality, timeliness, and importance of the lead or the work
performed by the Assisting Party pursuant to an Acceptance of a Request.

3.4      If either Party collects any license fees or royalties pursuant to a
final judgment or settlement of any cause of action related to a Third Party
License, and if the other Party provided assistance to such Party relating to
such effort, all expenses directly related to the cause of action, including but
not limited to reasonable attorneys' fees, court costs, expert witness fees,
expenses, and damages incurred by the Licensing Party that collects such license
fees or royalties shall be deducted from such judgment or settlement prior to
the determination of the amount of the Shared Revenue Payment pursuant to
sections 3.1(a) and 3.2 above.

All Shared Revenue Payments made pursuant to this Agreement shall be in United
States Dollars and shall be made no later than the end of the calendar month
immediately following receipt of such fees. If a Licensing Party for any reason
is required to refund a license fee or royalty, in whole or in part, to any
third party, the other Party shall refund the amount of the payment attributable
to the amount of such refund based on its percentage of Shared Revenue Payment.

For any Third Party License, the Licensing Party shall be responsible for
ensuring that all tax issues are fully evaluated and properly addressed in any
such Third Party License agreement. All payments made hereunder are exclusive of
any federal, local or other governmental taxes, duties, licenses, fees,
interest, penalties, excises or tariffs ("Charges"), including those imposed on
the Third Party Licenses granted pursuant to this Agreement. Any taxes payable
on or with respect to a license fee, royalty, Shared Revenue Payment, payment of
hourly fees, or any other payment made hereunder are the responsibility of the
recipient.

Upon at least thirty (30) days prior written notice to the other Party, and at
the auditing Party's sole cost and expense, such Party's auditors or a
nationally-recognized certified public accounting firm on such Party's behalf,
shall have the right to inspect such of the other Party's business books and
records as may be reasonably necessary for the auditing Party to verify the
accuracy of the Payments and to verify the other Party's compliance with all
other terms hereunder. Any inspection of the other Party's books and records
pursuant to this section shall take place at a mutually agreeable time and with
reasonable notice and shall be conducted at the other Party's premises, only
during the other Party's normal business hours, and in a manner which does not
unreasonably interfere with the other Party's business operations.

All payments due hereunder shall be made by wire transfer to the following
account:

Payment instructions may be changed by a Party at any time upon prior written
notice to the other Party.

3.9      Each Party acknowledges that the other Party may enter into Third Party
Licenses without requesting the other Party's assistance under this Agreement,
and if a Party enters into such Third Party Licenses, such Party shall not be
required to make any payments to the other Party with respect to such Third
Party Licenses. If a Party can demonstrate that it had Licensing Lead Awareness
that is substantially the same as the information provided to such Party in a
Licensing Lead provided by the other Party prior to the date on which the lead
was provided, and such Party does not request any assistance from the other
Party regarding the lead, no payments shall be owed with respect to any
particular Third Party Licenses that such Party enters into regarding such
opportunity.

3.10     Except regarding payment of an hourly fee pursuant to this Agreement,
neither Party shall have a claim or remedy against the other Party if a
particular Third Party License is not entered into, regardless of the amount of
assistance provided pursuant to this Agreement. Each Party acknowledges that the
sole manner in which it shall be compensated pursuant to this Agreement is in
accordance with sections 3.1 and 3.2.

4.       CONFIDENTIAL INFORMATION

4.1      Scope of Confidential Information. Each Party acknowledges that it may
receive information and material that is the other Party's confidential,
proprietary or trade secret information. As used herein, "Confidential

disclosed by or on behalf of a Party, whether written or oral, in the course of
this Agreement or in contemplation hereof including, without limitation, all
specifications, drawings, sketches, schematics, models, samples, tools,
algorithms, technical or business information, research and development,
production and engineering processes, costs, profit and margin information,
customer lists, customer information, marketing, production and future business
plans and any information or materials of a Party's agents, subcontractors or
other suppliers.

4.2      Use of Confidential Information. Each Party agrees to take all steps
reasonably necessary to hold in trust and confidence the other Party's
Confidential Information. Each Party hereby agrees to hold the other Party's
Confidential Information in strict confidence, not to disclose it to third
parties or to use it, in any way, commercially or otherwise, other than as
permitted under this Agreement. Each Party will limit the disclosure of the
other Party's Confidential Information to employees, agents and subcontractors
with a need to know and who have been advised of the proprietary nature thereof.
Each Party's obligations set forth herein shall remain in effect for three (3)
years from the receipt of the other Party's Confidential Information, but such
obligation of confidentiality will not expire for information considered or
deemed to be a trade secret under applicable law.

4.3      Exceptions. Notwithstanding the other provisions of this Agreement,
nothing received by one Party, as the receiving Party, from the other Party, as
disclosing Party, will be considered to be the disclosing Party's Confidential
Information if: (a) it has been published or is otherwise available or becomes
available to the public other than by a breach of this Agreement; (b) it has
been rightfully and lawfully received by the receiving Party from a third Party
without limitations or restrictions on its use or disclosure; (c) it has been
independently developed by the receiving Party by personnel having no access to
disclosing Party's Confidential Information; (d) it was known by the receiving
Party prior to its first receipt from disclosing Party and such knowledge can be
substantiated by reasonable documentation; (e) it is hereafter disclosed by
disclosing Party without restriction on further disclosure; or (f) it is
required to be disclosed to any governmental agency or court of competent
jurisdiction pursuant to a

7.       INDEMNIFICATION

7.1      Each Party shall indemnify (as the "Indemnifying Party"), defend and
hold harmless the other Party (the "Indemnified Party"), at the Indemnifying
Party's expense, against any claim, suit or proceeding brought against the
Indemnified Party to the extent resulting from, relating to or arising out of

obligation to indemnify shall include, without limitation, an obligation to pay
any costs including, but not limited to, reasonable attorneys' fees, court
costs, expert witness fees, expenses, and damages awarded to third parties or
incurred by the Indemnified Party. The Indemnifying Party may settle, at the
Indemnifying Party's sole discretion and expense, any claim, suit or other
action against the Indemnified Party for which the Indemnifying Party is
responsible under this section provided that such settlement shall not limit,
unduly interfere with or otherwise adversely affect the rights granted to the
Indemnified Party or the Indemnifying Party's obligations under this Agreement
or impose any liability on the Indemnified Party. The Indemnified Party reserves
the right to employ counsel at its own expense and to assist and participate in
the defense and/or settlement of any claim.

8.       TERMINATION

8.1      Term. The term of this Agreement shall be one (1) year beginning on the

(1) year terms unless either Party gives ninety (90) days prior written notice
of its intent to terminate the Agreement at the end of the then-current term.

8.2      Termination for Cause. Either Party may terminate this Agreement by
written notice: (a) if the other Party files a petition in bankruptcy, or has
filed against it an involuntary petition in bankruptcy not dismissed within
ninety (90) days after filing, or applies for or consents to the appointment of
a receiver, custodian, trustee or liquidation, or makes a general assignment for
the benefit of creditors, or (b) upon a material breach of this Agreement by the
other Party which has not been cured within sixty (60) days after written notice
describing such breach.

8.3      Either Party may immediately terminate this Agreement if over fifty
percent (50%) of the shares of common stock of the other Party is acquired by a
third party.

         (a) To the extent that the Licensing Party owes Shared Revenue Payments
         to the Assisting Party for Third Party Licenses, such Shared Revenue
         Payments shall be owed only if such Third Party Licenses are entered
         into within two (2) years after the termination date and if the
         Assisting Party provided assistance to the Licensing Party prior to the
         termination date.

         (b) No hourly fees shall be payable for hours worked after the date of
         termination, unless otherwise agreed to in writing by the Parties.

         (c) For license fees or royalties collected by a Licensing Party after
         the termination date for a Third Party License entered into prior to
         the termination date, the Licensing Party shall continue to make Shared
         Revenue Payments to the other Party to the extent it is obligated to do
         so pursuant to this Agreement for the duration of that License
         Agreement.

earthquakes or other natural disasters. A Party claiming the benefit of this
Force Majeure section must provide the other Party with timely notice of the
facts and circumstances regarding such claim, and performance is excused only
for so long as the force majeure condition subsists.

9.2      Compliance with Laws. Both Parties shall act in strict compliance with
all applicable laws, ordinances, regulations and other requirements of any and
all national, federal, state, county, municipal or other governmental
authorities, and obtain all permits, licenses or other consents necessary for
the performance of its duties under this Agreement. Further, each Party shall
indemnify, defend and hold the other Party harmless from any claim or damages
(inclusive of reasonable attorneys' fees and expenses incurred) made against the
other as a result of the indemnifying Party's failure to act in compliance with
the foregoing.

9.3      Notice. Any notice or reports required or permitted to be given under
this Agreement shall be given in writing and shall be deemed to have been duly

9.4      Attorneys' Fees. In the event that suit is brought under this Agreement

9.5      Waiver. The failure of either Party to exercise any right or option

                                                                   EXHIBIT 10.53

9.6      Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of Georgia without giving effect to
principles of conflict of law. The jurisdictional venue for any legal
proceedings related to this Agreement shall be held in any applicable local,
state or federal court located within Atlanta, Georgia.

9.7      Assignment. No assignment, delegation or other use of any right or duty
under this Agreement may be made by either Party without the prior written
consent of the other Party, which shall not be unreasonably withheld or delayed.
Any such assignment, delegation, or other use attempted to be made without such
written consent shall be void for all purposes. Notwithstanding the foregoing,
BIPMARK shall have the absolute right to assign this Agreement or any of its
rights or obligations hereunder to BellSouth Corporation or any direct or
indirect subsidiary of BellSouth Corporation now existing or hereafter acquired
or created, or to any entity acquiring all or substantially all of the assets of
BellSouth Corporation. This Agreement will be binding upon the Parties'
respective successors and permitted assigns.

9.8      Injunctive Relief. Unauthorized use of a Party's Confidential
Information or Intellectual Property may diminish the value of such to such
Party. Therefore, if a Party breaches any of its obligations hereunder, the
non-breaching Party shall be entitled to equitable relief to protect its
interests therein, including but not limited to injunctive relief as well as
monetary damages.

9.9      Publicity. Neither Party shall disclose the terms and conditions of
this Agreement to any outside party, except as may be required by law or an
order of a court of competent jurisdiction without the mutual consent of both
Parties. Each Party shall have the right to issue a press release relating to a
Third Party Licenses of its own intellectual property under this Agreement, but
neither Party may use the other Party's name or reference the other Party in any
way in any press release or other publicity without the prior written approval
of the other Party.

9.10     Independent Contractors. The relationship of BIPMARK and CINGULAR is
not altered in any way by this Agreement. For purposes of this Agreement,
BIPMARK and CINGULAR are independent contractors, and nothing contained in this
Agreement shall be construed to create an agency relationship between the
Parties or to allow a Party to create or assume any obligation on behalf of the
other Party for any purpose whatsoever. Neither Party will make any contract,
agreement, warranty, or representation on behalf of the other Party, or incur
any debt or other obligation in the other Party's name, or act in any manner
which has the effect of making that Party the apparent agent of the other.
Neither Party will assume liability for, or be deemed liable as a result of, any
such action by the other Party. Neither Party will be liable by reason of any
act or omission of the other Party in the conduct of its business or for any
resulting claim or judgment.

9.11     Severability. Each term of this Agreement is severable. If a provision
is determined to be invalid or unenforceable under applicable law, such
determination will not affect the other terms of this Agreement, which other
terms will continue to be enforced as if the invalid or unenforceable provisions
were omitted. In addition, if any provision of this Agreement, for any reason,
is declared to be invalid or unenforceable, the Parties will substitute a valid
or enforceable provision that, to the maximum extent possible in accordance with
applicable law, preserves the original intentions and economic positions of the
Parties.

9.12     Overdependence. Neither Party knows the other Party's dependence on
assistance required in order to have an effective licensing program, and apart
from the obligations set forth herein, neither Party shall be liable to the
other Party for not providing any or all of the requested assistance, even if
the lack of such assistance causes the potential licensing Party to forego a
licensing opportunity or the lack of such assistance detrimentally affects their
overall licensing program.

9.13     Right to Competition. Nothing in this Agreement will prevent either
Party from independently developing products or services which may compete with
or be similar to products or services of the other Party, or in the case of
overlapping or jointly owned Intellectual Property, from competing with each
other with respect to potential licensing opportunities.

9.14     Entire Agreement. This Agreement contains the entire understanding of
the Parties with respect to the subject matter contained herein and supersede
all terms and conditions in any other communications or documents

                  WHEREAS, each of the Sellers has commenced a case
(collectively, the "Chapter 11 Cases") under Chapter 11 of the Bankruptcy Code
in the United States Bankruptcy Court for the Southern District of New York (the

case number 98-B 21529(ASH));

                  WHEREAS, Sellers have been granted authorizations by the FCC
to construct and operate broadband PCS systems on the frequencies and in the
BTAs as described on the attached Exhibit A (collectively, the "Licenses"); and

                  WHEREAS, Sellers wish to sell the Licenses to Buyer, and Buyer
wishes to purchase the Licenses from Sellers, in the manner and subject to the
terms and conditions set forth in this Agreement and pursuant to Section 363 of
the Bankruptcy Code.

                  NOW, THEREFORE, in consideration of the mutual covenants
herein and other good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, the parties hereto, each intending to be legally
bound, do hereby agree as follows:

                                   ARTICLE I.
                                PURCHASE AND SALE

                  1.1      Purchase and Sale. On the Closing Date, and upon the
terms and conditions set forth herein and subject to the approval of the
Bankruptcy Court pursuant to Section 363 of the Bankruptcy Code, Sellers shall
sell, transfer, convey, assign, and deliver to Buyer, and Buyer shall purchase
and accept from Sellers, all of Sellers' right and interest in and to the

                  1.2      Purchase Price Payable at Closing.

($1,400,000,000.00). At the Closing, in exchange for the Licenses, Buyer shall
(i) pay or deliver to Sellers, by wire transfer in immediately available funds

prior to Closing by Sellers), the Purchase Price, reduced by (a) the Indemnity
Escrow Amount and (b) the FCC Direct Payment, (ii) deliver the Indemnity Escrow
Amount to the Escrow Agent to be held in escrow and administered in accordance
with the terms of the Escrow Agreement and (iii) deliver, on behalf of the
Sellers, the FCC Direct Payment to the United States Treasury. The payments made
by Buyer pursuant to, and in the manner required by, this Section 1.2(a) shall
constitute payment in full by Buyer to all of the Sellers.

                  (b)      At or before the Closing, the parties shall make a
good faith allocation of the Purchase Price. After the Closing, the parties
shall make consistent use of such allocation, fair market value and useful lives
for all tax purposes and in all filings, declarations and reports with the IRS
in respect thereof, including the reports required to be filed under Section
1060 of the Internal Revenue Code, if any.

                  1.3      Excluded Liabilities. Buyer shall not assume, or
otherwise be responsible for any liabilities, obligations, taxes or indebtedness
of Sellers or any of their Affiliates (including, without limitation, any such
liabilities, obligations, taxes or indebtedness related to the Licenses),
whether direct or indirect, liquidated or unliquidated, known or unknown,
whether accrued, absolute, contingent, matured, unmatured or otherwise, and
whether arising out of occurrences prior to, at or after the Closing
(collectively, the "Excluded Liabilities"). Without limiting the generality of
the foregoing, all of Sellers' cost sharing obligations to other PCS licensees
(or to microwave incumbents) relating to its operations prior to the Closing and
all of Sellers' relocation obligations triggered by its operations prior to the
Closing (each such liability a "Microwave Relocation Liability" and,
collectively, the "Microwave Relocation Liabilities") shall remain Sellers'
obligation and responsibility and shall not be assumed by or otherwise become
the responsibility of Buyer, even if such costs and obligations are not brought
to the attention of either Sellers or Buyer until after the Closing. Allowed
claims for payment of Microwave Relocation Liabilities arising prior to the
Closing shall be treated as administrative expenses in the Sellers' Chapter 11
Cases, entitled to priority of payment with other administrative expenses
pursuant to Section 503(b) of the Bankruptcy Code and shall be paid, to the
extent and in the amount of the liability, as determined by agreement of the
Sellers or by Final Order of the Bankruptcy Court, pursuant to (x) the plan of
reorganization of the Sellers as confirmed by Final Order of the Bankruptcy
Court or (y) at the Sellers' option, otherwise pursuant to Final Order of the
Bankruptcy Court. From and after the Closing, the Sellers shall maintain an
adequate reserve for payment of administrative expenses, including, but not
limited to, Microwave Relocation Liabilities. Notwithstanding any provision of
this Agreement to the contrary, the Sellers, and each of them, and all parties
in interest in the Sellers' Chapter 11 Cases shall have the right to object to
any and all claims for payment of Microwave Relocation Liabilities, and the
Bankruptcy Court shall retain jurisdiction to consider and determine the
allowance of such claims.

permits, licenses, franchises, variances, exemptions, orders, operating rights
and other state, local and federal governmental authorizations, consents and
approvals, if any, necessary to conduct their business as presently conducted,

ability to consummate the transactions contemplated by this Agreement.

                  (b)      Sellers have performed as of the date of this

breach or default under the Licenses which permits or, after notice or lapse of
time or both, would permit revocation, cancellation, suspension or adverse
modification of the Licenses, or which might adversely affect the rights of
Sellers under the Licenses, except for the occurrence of which would not impair
or otherwise affect Buyer's interest in and right to control and operate the
Licenses free and clear of Encumbrances or would not be reasonably likely to
delay or impair Sellers' ability to consummate the transactions contemplated by
this Agreement. Except as set forth in Schedule 3.4(c), the Licenses are valid

Order and the FCC Consent becoming Final Orders and HSR Approval, the Licenses
may be assigned and transferred to Buyer in accordance with this Agreement and
will continue in full force and effect thereafter without the consent, approval,
or act of, or the making of any filing with, any Governmental Body. The Licenses
(i) were granted on the grant dates specified on Exhibit A and (ii) expire on
the expiration dates specified on Exhibit A.

                  (c)      Except for the Chapter 11 Cases and except as set
forth on Schedule 3.4(c), (i) there are no judicial or administrative claims,

knowledge of the Sellers, threatened against any of the Sellers or any Affiliate
thereof relating to any of the Licenses in, before or by any court or
Governmental Body, (ii) there is no judgment, decree or injunction outstanding
against any of the Sellers or any Affiliate thereof relating to or involving the
Licenses, (iii) there is no rule or order outstanding against any of the Sellers

Sellers is qualified under the FCC's rules and the Communications Act to hold
and convey the Licenses held by it, and has been so qualified continuously since
the filing of the applicable FCC Form 175 application to participate in bidding
on the right to use the frequencies encompassed by each of the Licenses. Except
as set forth in Schedule 3.4(c), to the knowledge of Sellers, there are no facts
or circumstances relating to the FCC qualifications of Sellers or any of their
Affiliates that would prevent or materially delay the FCC's grant of any FCC
Form 603 (or other appropriate form) application under FCC rules and the
Communications Act.

                  (e)      Each of the Sellers has submitted to the FCC, on Form

applicable benchmark notification is specified on Exhibit A.

Schedule 3.5, each of the Sellers validly holds and has the right to control and
operate its Licenses, free and clear of all Encumbrances. Notwithstanding
anything to the contrary in this Agreement, upon delivery to Buyer on the
Closing Date, subject to the Sale Order and the FCC Consent having become Final
Orders, Buyer will validly hold and have the right to control and operate the
Licenses, free and clear of all Encumbrances. There are no obligations under 47
C.F.R. ss. 1.2111(d), 47 C.F.R. ss. 24.714 or otherwise, to repay to the U.S.
Government or any other party bidding credits utilized by Sellers in connection
with the auctions in which the right to use the frequencies encompassed by the
Licenses was awarded that are not satisfied by the FCC Direct Payment.

aware of any reasonable basis for any such investigation, claim, action, suit or
proceeding.

                  3.7      No Finder. Except for UBS Investment Bank (formerly
UBS Warburg LLC), to which any and all obligations relating to the transfer of
the Licenses hereunder will be satisfied solely by the Sellers, no broker or
finder has acted on behalf of the Sellers in connection with the transactions

Licenses which seeks to enjoin or rescind the transactions contemplated by this
Agreement or otherwise prevent Sellers from complying with the terms and

Bankruptcy Court in effect that would prevent Sellers from complying with the
terms of this Agreement.

under the Investment Company Act of 1940, as amended, or subject to regulation
under such Act, or controlled by an investment company, unit investment trust or

fulfilling its obligations under this Agreement) or (ii) any actions nor file
any pleadings, other than those specifically contemplated by this Agreement,
before any court or Governmental Body with respect to Sellers, the Licenses, or
any of Sellers' other assets or operations without the prior written consent of
Sellers (although nothing herein shall prevent Buyer from asserting its rights

conditions imposed on Buyer or any of its Affiliates, (b) the FCC Consent shall

any appeal or challenge to the Sale Order. Without limiting the generality of
the foregoing, the parties specifically agree that if the FCC Consent does not

C.F.R. ss. 1.2111 and ss. 24.714, subject to delivery of the FCC Direct Payment

full payment, and satisfies all conditions, required under 47 C.F.R. ss. 1.2111
and ss. 24.714 and (ii) grant any other waivers requested necessary to implement
the transfers contemplated by this Agreement, or otherwise grant such relief
requested, as part of any application seeking such FCC Consent, then the FCC

HSR Act shall have been obtained without any adverse conditions imposed on Buyer
or any of its Affiliates. The applicable waiting period under the HSR Act, if
applicable, shall have expired or been terminated.

Order, Buyer shall have received affirmative releases of all Encumbrances

contemplated hereby, or which is reasonably likely to prevent Buyer from
complying with the terms of this Agreement.

                  For purposes of this Section 9.1, (i) to the extent any facts
or circumstances can be deemed a breach of a representation or warranty by any

and conditions of this Article IX, Buyer agrees to indemnify, defend, and hold
harmless the Seller Indemnified Parties from, against, for, and in respect of
any and all Losses asserted against, imposed upon, or incurred by the Seller
Indemnified Party (whether before or after the Closing) arising out of:

                  (a)      the breach of any representation or warranty of Buyer
contained in or made pursuant to this Agreement or in any certificate, Schedule,
or Exhibit furnished by Buyer in connection herewith; or

                  (b)      the breach of any covenant or agreement of Buyer

                  9.3      Procedures for Indemnification.

                  (a)      An Indemnification Claim shall be made by the
Indemnified Party by delivery of a written declaration to the Indemnitor
requesting indemnification and specifying the basis on which indemnification is
sought and the amount of asserted Losses and, in the case of a Third Party
Claim, containing (by attachment or otherwise) such other information as the
Indemnified Party shall have concerning such Third Party Claim.

                  (b)      If the Indemnification Claim involves a Third Party
Claim, the procedures set forth in Section 9.4 hereof shall be observed by the
Indemnified Party and the Indemnitor.

                  (c)      If the Indemnification Claim involves a matter other
than a Third Party Claim, the Indemnitor shall have twenty (20) calendar days to
object to such Indemnification Claim by delivery of a written notice of such
objection to the Indemnified Party specifying in reasonable detail the basis for
such objection. Failure to timely so object shall constitute a final and binding
acceptance of the Indemnification Claim by the Indemnitor and the

Claim shall be paid in accordance with Section 9.3(d) hereof. If an objection is
timely interposed by the Indemnitor, then the Indemnified Party and the
Indemnitor shall negotiate in good faith for a period of thirty (30) calendar
days from the date (such period is hereinafter referred to as the "Negotiation
Period") the Indemnified Party receives such objection. Subject to the
provisions of Section 11.13, nothing herein shall prevent the parties from
seeking equitable or injunctive relief in a court of equity with respect to such
dispute.

                  (d)      Upon determination of the amount of an
Indemnification Claim that is binding on both the Indemnitor and the Indemnified
Party, the Indemnitor shall pay the amount of such Indemnification Claim from
the Indemnity Escrow Amount if such payment is due from the Sellers, or by wire
transfer of immediately available funds if such payment is due from the Buyer,
within ten (10) days of the date such amount is determined. During the pendency
of the Chapter 11 Cases, any obligation of Sellers under this Article IX shall
be treated as an administrative expense claim in the Chapter 11 Cases pursuant

                  (a)      In the event a claim, suit or proceeding by a third
party is made or filed against any Indemnified Party (a "Third-Party Claim"),
such Indemnified Party shall promptly after the receipt of written notice of
such claim, suit or proceeding notify the Indemnitor in writing of such claim,
suit or proceeding and thereafter the Indemnified Party shall promptly deliver
to the Indemnitor copies of all notices and documents (including court papers)
received by the Indemnified Party relating to the Third-Party Claim; provided,
however, that the failure of the Indemnified Party to give timely notice of any
such claim, suit or proceeding or to make timely delivery of any such notices or
documents shall not relieve the Indemnitor of its indemnification obligations
with respect to such claim, suit or proceeding except to the extent that such
Indemnitor has been materially prejudiced thereby.

                  (b)      The Indemnitor shall have thirty (30) days (or such
lesser time as may be necessary to comply with statutory response requirements
for litigation claims) from receipt of the indemnification claim (the "Notice
Period") to notify the Indemnified Party, (i) whether or not the Indemnitor
disputes its Liability to the Indemnified Party with respect to such claim and
(ii) notwithstanding any such dispute, whether or not the Indemnitor desires, at
its sole cost and expense, to defend the Indemnified Party against such claim.

                           (i)      In the event that the Indemnitor notifies
the Indemnified Party within the Notice Period that it desires to defend the
Indemnified Party against such claim then, except as hereinafter provided, the
Indemnitor shall have the sole and absolute right after the receipt of notice,
at its option and at its own expense, to be represented by counsel of its choice
and to control, defend against, negotiate, settle or otherwise deal with such
proceeding, claim or demand; provided, however, that the Indemnified Party may,
at its election, participate in, but not control, the defense of any such
proceeding, claim or demand through counsel of its own choice, but the fees and
expenses of such counsel shall be at the expense of the Indemnified Party,

the Indemnified Party shall have been advised by such counsel that there may be
one or more legal defenses available to it that are different from or in
addition to those available to the Indemnitor (in which case, if the Indemnified
Party notifies the Indemnitor in writing that it elects separate counsel at the
expense of the Indemnitor, the Indemnitor shall not have the right to assume the
defense of such action on behalf of the Indemnified Party with respect to such
defenses).

                           (ii)     Except where the Indemnitor (A) timely
elects to defend the Indemnified Party against such claim or demand (in which
case Sections 9.4(b)(i) and (ii) shall govern), or (B) Indemnitor disputes its
Liability in a timely manner under this Section 9.4, the Indemnitor shall be
conclusively liable for the amount of any Loss resulting from such claim or
defense which is unsuccessful.

                  (c)      The Indemnified Party and the Indemnitor shall
cooperate with each other in all reasonable respects in connection with the
defense of any Third-Party Claim, including making available records relating to
such claim and furnishing, without expense to the Indemnitor, management
employees of the Indemnified Party as may be reasonably necessary for the
preparation of the defense of any such claim or for testimony as witness in any
proceeding relating to such claim.

                  (d)      Neither the Indemnitor nor the Indemnified Party may
settle any such proceeding, claim or demand if such settlement obligates the
other Party to pay money, to perform obligations or to admit liability without
the consent of the other Party, such consent not to be unreasonably withheld.
Consent shall be presumed where the Party given written notice of the proposed
settlement has not responded within twenty (20) calendar days of such written
notice.

                  (e)      Within thirty (30) days after (i) any final judgment
or award shall have been rendered by a court or governmental body of competent
jurisdiction and the time in which to appeal therefrom has expired, (ii) a
settlement shall have been consummated or (iii) the Indemnified Party and the
Indemnitor shall arrive at a mutually binding agreement with respect to each
separate matter alleged by the Indemnified Party to be indemnified, the
Indemnified Party shall forward to the Indemnitor notice of any sums due and
owing by the Indemnitor with respect to such matter, and the Indemnitor shall
promptly pay all undisputed sums so owing to the Indemnified Party.

                  9.5      Certain Limits on Indemnification.

                  (a)      Sellers shall not have any obligations to provide
indemnification for Losses pursuant to Sections 9.1 except to the extent that
the aggregate amount of all such Losses exceeds Two Hundred Fifty Thousand
Dollars ($250,000) (the "Basket Amount"), in which case Sellers shall be liable
to Buyer only for such Losses in excess of the Basket Amount. The maximum
obligation of Sellers to provide indemnification for Losses pursuant to Section
9.1 shall be limited to an aggregate amount equal to the Indemnity Escrow
Amount.

indemnification for Losses pursuant to Section 9.2 except to the extent that the
aggregate amount of all such Losses exceeds the Basket Amount, in which case
Buyer shall be liable to Sellers only for such Losses in excess of the Basket
Amount. The maximum obligation of Buyer to provide indemnification for Losses
pursuant to Section 9.2 shall be limited to an aggregate amount equal to the
Indemnity Escrow Amount.

                  (c)      In the event any of the Sellers shall have filed, or
consented to the filing of, a plan of reorganization with the Bankruptcy Court
prior to the Closing, no Indemnified Party shall be entitled to indemnification
under this Article IX unless such Indemnified Party has delivered written notice
of the indemnification claim or demand to the Indemnitor prior to the later of
(a) the effective date of a confirmed plan of reorganization of the Sellers and
(b) three months after the Closing Date. In the event no Seller shall have
filed, or consented to the filing of, a plan of reorganization with the
Bankruptcy Court prior to the Closing, no Indemnified Party shall be entitled to
indemnification under this Article IX unless such Indemnified Party has
delivered written notice of the indemnification claim or demand to the
Indemnitor prior to the effective date of a confirmed plan of reorganization of
the Sellers. Notwithstanding the preceding provisions of this Section 9.5(c),
the indemnification obligations for claims or demands for which written notice
is given prior to such later date shall continue until the final resolution of
each such claim or demand. Sellers' obligations under this Article IX shall be
included in any plan of reorganization filed by, or permitted to be filed by,
Sellers.

                  (d)      The Losses incurred by an Indemnified Party shall,
for purposes of determining the threshold and maximum levels thereof in
accordance with Sections 9.5(a) and 9.5(b) hereunder, be offset by any insurance
proceeds actually received by the Indemnified Party with respect thereto.

___________ banking corporation (the "Escrow Agent").

         WHEREAS, each of the Sellers and Buyer have entered into an Purchase
Agreement dated August 4, 2003 (the "Asset Purchase Agreement") pursuant to
which Buyer will purchase all rights and interests in the Licenses from Sellers.
Any capitalized term used but not defined herein shall have the meaning set
forth in the Asset Purchase Agreement; and

         WHEREAS, the Asset Purchase Agreement contemplates the establishment of
an escrow account to provide, as the exclusive remedy, a fund for satisfaction
of certain post-closing indemnification claims made by Buyer against Sellers
pursuant to Article IX of the Asset Purchase Agreement; and

         WHEREAS, Escrow Agent is willing to accept the escrow fund and to hold
and distribute the escrow fund in accordance with the terms and conditions set
forth herein.

         NOW, THEREFORE, in consideration of the mutual promises contained
herein, and other good and valuable consideration, the receipt and sufficiency
of which are hereby acknowledged, the parties agree as follows:

         1.       Appointment of Escrow Agent. Buyer and Sellers hereby

invested in U.S. treasury securities, money market funds or direct obligations
of the United States of America or obligations the principal of and interest on
which are unconditionally guaranteed by the United States of America. The
Indemnification Escrow Amount is to be held, administered and paid by Escrow
Agent as provided herein. Escrow Agent acknowledges receipt of the
Indemnification Escrow Amount and agrees to hold, administer and pay the same in
accordance with the terms of this Agreement and not permit any withdrawal
thereof except pursuant to the terms hereof.

         3.       Disposition of Indemnification Escrow Amount. At any time
prior to the expiration of the Sellers' indemnification obligations pursuant to
Section 9.5 of the Asset Purchase Agreement (the "Termination Date"), Buyer may
deliver to the Escrow Agent a notice of an Indemnification Claim (a "Notice of
Claim"), with a copy contemporaneously delivered to Sellers. If the Escrow Agent
has not received from Sellers a written Notice of Dispute (as hereinafter
defined) within twenty (20) calendar days after Escrow Agent receives the Notice
of Claim (with a copy of such Notice of Dispute having been sent
contemporaneously by Sellers to Buyer) stating that Sellers dispute the claim
contained in the Notice of Claim, the portion of the Indemnification Escrow
Amount specified in the Notice of Claim shall be disbursed by the Escrow Agent
to Buyer as soon as practicable in accordance with the directions contained
therein. Subject to Section 4 of this Agreement, if the Escrow Agent receives a
Notice of Dispute from Sellers within the ten-day period, the Escrow Agent shall
not release the portion of the Indemnification Escrow Amount relating to the
Notice of Dispute until the receipt of (i) written instructions executed jointly
by Sellers and Buyer directing the Escrow Agent to cause the delivery of all or
a specified portion of the Indemnification Escrow Amount to the appropriate
party or parties (a "Joint Notice of Release") or (ii) a final, binding and
non-appealable court order with respect thereto. The Escrow Agent shall
thereupon distribute within twenty (20) calendar days a portion of the
Indemnification Escrow Amount in accordance with the directions contained in the
Joint Notice of Release or the final, binding and non-appealable court order.

         4.       Termination of Agreement and Release of Escrow Fund.

                  (a)      Subject to the provisions of Section 3 hereof, the
portion of the Indemnification Escrow Amount not subject to a Notice of Claim
and not previously disbursed shall be disbursed to Sellers, and this Agreement,
except for the provisions in Sections 7 and 8 hereof, shall terminate on the
Termination Date, unless prior to the close of business on the Termination Date
(or the close of business on the business day prior to the Termination Date, if
the Termination Date is not a business day) the Escrow Agent shall have
received: (i) any Notice of Claim for which the twenty (20) day period for
filing the appropriate Notice of Dispute shall not have expired ("Outstanding
Notice of Claim"); or (ii) any Notice of Claim for which the appropriate Notice
of Dispute shall have been filed and for which the Escrow Agent shall not have
received the appropriate Joint Notice of Release or a final, binding
non-appealable court order with respect thereto ("Outstanding Notice of
Dispute"). The Escrow Agent shall be entitled to rely upon a joint notice
executed by Sellers and Buyer as to the satisfaction of the conditions resulting
in a termination of the escrow fund.

                  (b)      If the Escrow Agent is in possession of any
Outstanding Notice of Claim, or Outstanding Notice of Dispute on the Termination
Date, the Escrow Agent shall disburse to Sellers within ten (10) days after the
Termination Date the portion of the Indemnification Escrow Amount in excess of

of Claim for which the appropriate Notice of Dispute shall not have been
received by the Escrow Agent within the applicable ten day period shall be

hereunder, or if conflicting demands or notices are made upon Escrow Agent, or
in the event Escrow Agent in good faith is in doubt as to what action it should
take hereunder, the parties expressly agree and consent that Escrow Agent shall
have the absolute right: (i) to stop all further proceedings in, and performance
of, this Agreement and of all instructions received hereunder; (ii) to file a
suit in interpleader and obtain an order from a court of competent jurisdiction
requiring all persons involved to interplead their several claims and rights
among themselves and with Escrow Agent, or (iii) to deposit all funds held
hereunder into the registry or custody of a court of competent jurisdiction and
thereupon be discharged of all further duties hereunder.

                  (b)      While any interpleader proceeding arising out of or
relating to this Agreement is pending, whether the same be initiated by Escrow
Agent or by others, Escrow Agent shall have the right, at its option, to stop
all further proceedings in, and performance of, this Agreement and instructions
received hereunder until all differences shall have been resolved by agreement
or until the rights of all parties shall have been fully and finally determined
by the interpleader proceedings. The rights of Escrow Agent under this Section 6
are in addition to all other rights which it may have by law or otherwise.

                                                                   EXHIBIT 10.54

         7.       Escrow Agent's Fees and Expenses. The reasonable compensation
of Escrow Agent as set forth in Schedule A hereto and all expenses,
disbursements and advances (including reasonable attorneys' fees) incurred by
the Escrow Agent directly in connection with carrying out Escrow Agent's duties
hereunder shall be paid jointly by Sellers and Buyer.

         8.       Indemnification. Each of the Sellers and Buyer, jointly and
severally, agree to indemnify, protect and save and hold Escrow Agent and its
successors and assigns, and each of its directors, officers, agents and
employees, harmless from and against all liabilities, obligations, losses,
damages, penalties, claims, actions, suits, costs and expenses (including
reasonable attorneys' fees) of whatsoever kind or nature imposed on, incurred by
or asserted against Escrow Agent or such other persons that in any way relate to
or arise directly or indirectly out of the execution and delivery of this
Agreement or any action taken hereunder; provided, however, that Sellers and
Buyer shall have no such obligation to indemnify and save and hold Escrow Agent
harmless from any liability incurred by, imposed upon or asserted against Escrow
Agent resulting from the gross negligence or willful misconduct of Escrow Agent.

         9.       Resignation by or Termination of Escrow Agent. Escrow Agent
may resign as such by delivering written notice to Sellers and Buyer at least
thirty (30) days prior to the effective date of such resignation. Sellers and
Buyer acting jointly, may terminate Escrow Agent from its position as such by
delivering written notice to Escrow Agent to such effect executed by Sellers and
Buyer at least thirty (30) days prior to the effective date of such termination
(unless such termination is as a result of Escrow Agent's breach of its
obligations hereunder, in which case the effective date of such termination
shall be any date specified in such notice by Sellers and Buyer). In the event
of such resignation by or termination of Escrow Agent, a successor Escrow Agent
shall be appointed by mutual agreement between Sellers and Buyer and written
notice of the appointment shall be delivered to Escrow Agent. Escrow Agent that
has been so terminated or has so resigned shall promptly deliver to the
successor Escrow Agent the entire remaining Indemnification Escrow Amount
(together with copies of all records pertaining thereto). From and after the
appointment of a successor Escrow Agent pursuant to this Section 9, all
references herein to Escrow Agent shall be deemed to be to such successor Escrow
Agent. If Sellers and Buyer fail to appoint a successor Escrow Agent within
thirty (30) days of the effective date of any resignation or termination
pursuant to this Section 9, then Escrow Agent shall have the right to institute
suit in a court of competent jurisdiction to have a successor Escrow Agent
appointed and to tender into the registry or custody of such court any portion
of or all of the Indemnification Escrow Amount, whereupon Escrow Agent shall be
discharged from its obligations hereunder, provided that the provisions of
Sections 7 and 8 shall survive such resignation or termination and Escrow Agent
shall be entitled to its compensation earned prior thereto and any
indemnification to which it may be entitled.

         10.      Notices.

         11.      General Provisions.

                  (a)      Assignment. The rights of any party under this
Agreement shall not be assignable by such party without the written consent of
the other parties; provided, however, that Buyer may, without the prior consent
of the other parties, assign any or all of its rights hereunder to (a) any
Affiliate of Buyer, (b) any successor of all or substantially all of Buyer's

lender of Buyer as collateral, but no such assignment shall relieve Buyer of any
of its obligations hereunder. This Agreement shall be binding upon and inure to
the benefit of the parties hereto and their successors and permitted assigns.

                  (b)      Amendment. This Agreement may not be amended or
modified except in a writing signed by all parties hereto.

                  (c)      Waiver. Failure to insist upon strict compliance with
any of the terms or conditions of this Agreement at any one time shall not be
deemed a waiver of such term or condition at any other time; nor shall any
waiver or relinquishment of any right or power granted herein at any time be
deemed a waiver or relinquishment of the same or any other right or power at any
other time.

                  (d)      Governing Law. This Agreement shall be governed by,
enforced and construed in accordance with the laws of the State of New York,
without regard to conflicts of law principles.

                  (e)      Invalid Provision. If any provision of this Agreement

                  (i)      Entire Agreement. This Agreement constitutes the
entire agreement of the parties with respect to matters set forth in this
Agreement, and supersedes any prior understanding or agreement, oral or written,
with respect to such matters.

                  (j)      Interpretations. No party shall be deemed to be the
draftsman hereof. Accordingly, neither this Agreement nor any uncertainty or
ambiguity herein shall be conclusively construed or resolved against any party
hereto, whether under any rule of construction or otherwise. This Agreement has
been reviewed, negotiated and accepted by all parties.

                  (k)      Execution in Counterparts. This Agreement may be
executed in any number of counterparts, each of which shall be an original, and
all such counterparts shall constitute one and the same Agreement, binding on
all the parties notwithstanding that all the parties are not signatories to the
same counterpart.

                  (l)      Jurisdiction. During the pendency of the Chapter 11
Cases, the parties agree that the Bankruptcy Court shall have the exclusive
jurisdiction over all disputes and other matters relating to the interpretation
and enforcement of this Agreement or any ancillary document executed pursuant
hereto. After the Chapter 11 Cases have been closed, the parties agree that the
federal court in the Southern District of New York (or in the absence of such
jurisdiction by such court, the courts of the State of New York located in the
City and County of New York) shall have the exclusive jurisdiction over all
disputes and other matters relating to the interpretation and enforcement of
this Agreement or any ancillary document executed pursuant hereto. Each of the
parties expressly consents to and agrees not to contest such exclusive
jurisdiction and, in addition, waives any rights to a jury trial.

                                    EXHIBIT D

                 SUBJECT MATTER OF OPINION OF COUNSEL TO SELLERS

         The Opinion of counsel(s) to the Sellers shall state the following:

         1.       Subject to entry of the Bidding Procedures Order, the Sale
Order becoming a Final Order and receipt of HSR Approval, the execution and
delivery of the Agreement by each of the Sellers, and the performance by each of
the Sellers of its obligations thereunder will not violate any federal, New York
or Delaware statute, rule or regulation applicable to any of the Sellers.
Counsel's opinion in this paragraph may express no opinion as to federal and
state laws and regulations applicable solely to telecommunications providers and
license holders.

         2.       To our knowledge, no consent, approval, authorization,
registration or declaration by, or filing with, any New York, Delaware or
federal governmental authority is required in connection with the execution and
delivery by each of the Sellers of the Agreement, the consummation by each of
the Sellers of the transactions contemplated thereby or the performance by each
of the Sellers of its obligations thereunder, except for the entry of the
Bidding Procedures Order, the Sale Order becoming a Final Order and receipt of
the HSR Approval.

         3.       None of the Sellers is an investment company, unit investment
trust or face-amount certificate company under the Investment Company Act of
1940, as amended, or subject to regulation under such Act, or controlled by an
investment company, unit investment trust or face-amount certificate company
under such Act (provided that control, for the purposes of this Opinion, is
defined as the ownership of twenty five percent (25%) or more of the voting
stock of any Seller).

         4.       Each of the Sellers holds and has the right to use its
Licenses. The Licenses are in full force and effect, and except for FCC actions
that have since been overturned by reviewing courts, have not been revoked,
suspended, cancelled or modified. The Licenses include all FCC licenses, permits
and authorizations necessary for Sellers to operate a broadband PCS system in
the markets corresponding to each License, as the systems are currently being
operated. Subject to the Sale Order and FCC Consent each becoming a Final Order
and receipt of HSR Approval, the execution and delivery of the Agreement by each
of the Sellers, and the performance by each of the Sellers of its obligations
thereunder will not violate any federal and state laws and regulations
applicable solely to telecommunications providers and license holders.

         5.       There are no actions, suits or proceedings before the FCC
pending or, to the best of our knowledge, threatened, against any of the Sellers
or the Licenses. There is no unsatisfied adverse FCC order, decree, or ruling
outstanding against any of the Sellers or the Licenses.

         6.       Sellers have filed a timely notification with the FCC stating
that they have

FINDS AND DETERMINES THAT

         A.       Debtors have articulated good and sufficient reasons for

         B.       The Bidding Procedures are reasonable and appropriate to
maximize the value to the estates of the Licenses;

         C.       The Agreement, the Bidding Procedures, and each of the
Break-Up Fee and the Expense Reimbursement were negotiated in good faith and
from an arms'-length bargaining position; and

         D.       The allowance of each of the Break-Up Fee and the Expense
Reimbursement are necessary to create competitive bidding and constitute the
sound exercise of Debtors' business judgment.

         E.       In order for all parties to be willing to proceed with the
Auction and the Sale, it is necessary and in the best interest of the NextWave
estates to require the Sale to be contingent upon and not proceed without the

         ORDERED, that capitalized terms used herein and not otherwise defined
herein shall have the meanings ascribed to them in the Bidding Procedures; and

         8.       Auction and Selection of Winning Bid

         If at least one Qualified Bid has been received (the "Topping Bid"),
the Debtors may conduct an Auction in accordance with the terms below. Only
Qualified Bidders (including the Proposed Purchaser) will be eligible to
participate at the Auction. At least two (2) business days prior to the Auction,
each Qualified Bidder (including the Proposed Purchaser or its Affiliates (as
defined in the Agreement), any of which is deemed a Qualified Bidder) who has
submitted a Qualified Bid must inform the Debtors whether it intends to
participate.

         At the Auction, only the Proposed Purchaser and such Qualified Bidders
who have submitted Qualified Bids in attendance at the start of the Auction
shall be entitled to make any additional bids. The additional bids will be made
and received in one room, on an open basis, and all other bidders shall be
entitled to be present for all bidding with the understanding that the true
identity of each bidder (including such bidder's ultimate parent) shall be fully
disclosed to all other bidders and that all material terms of each bid will be
fully disclosed to all other bidders throughout the entire Auction. Except as
expressly provided in this paragraph, all increases in bids following receipt of
the Topping Bid or any additional bids that meet such requirement shall be made
in increments of not less than $10 million. Bidding at the Auction shall
continue until such time as the highest and best offer is determined. The
Break-Up Fee shall be maintained for the benefit of the Proposed Purchaser or
any of its Affiliates with respect to any Topping Bid. For the avoidance of
doubt, during the Auction, for the Proposed Purchaser or any of its Affiliates
to top the Topping Bid or any other additional bid (other than its own), such
additional bid shall be not less than $10 million greater than the Topping Bid
or any other additional bid less the Break-Up Fee.

         The Auction will be conducted at 9:00 a.m. (New York time) to be held
at the offices of UBS Investment Bank, 299 Park Avenue, New York, New York 10171
on September 23, 2003, or such later date as Debtors, after consultation with
the Proposed Purchaser, the Committee, the FCC and the DIP Lender, may agree
(the "Auction"). The Auction will be conducted according to the specific process
set forth on Exhibit C attached hereto. For its Bid to be considered, a
Qualified Bidder must appear in person at the Auction or through a duly
authorized representative.

         At the conclusion of the Auction, Debtors, after consultation with the
Committee, the FCC, and the Lenders, will select the bid that they determine to
be the highest and best offer for the Licenses (the "Winning Bid"). Debtors
shall file a notice with the Court of such election and present the Winning Bid
to the Court for approval. The party that submits the Winning Bid shall be
referred to as the "Winning Bidder." Unless and to the

                  entitled to make any additional Bids. Bidding shall proceed in

         11.    The Debtors have demonstrated both: (a) good, sufficient and
sound business purpose and justification; and (b) compelling circumstances for
the Sale other than in the ordinary course of business, pursuant to section
363(b) of the Bankruptcy Code, in that, among other things: (i) the immediate
consummation of the Sale to the Purchaser is necessary and appropriate to
maximize the value of the Debtors' estates; and (ii) the Sale will provide the
means for the Debtors to maximize distributions to creditors and facilitate the
successful confirmation of a plan of reorganization.

         12.    Approval at this time of the Purchase Agreement and the FCC Term
Sheet and the consummation of the transactions contemplated thereby is in the
best interests of Debtors, their

creditors, and their estates. The Sale pursuant to the Purchase Agreement and
subject to FCC Regulatory Review and Approval is in the best interests of
Debtors, their creditors, and their estates and does not amount to a sale of
substantially all of the assets of any of the Debtors. Good and sufficient
business justification for consummating the Sale pursuant to section 363(b) of
the Bankruptcy Code has been established.

         13.    The terms and the conditions of the Purchase Agreement and the
FCC Term Sheet are fair and reasonable. The Purchase Agreement represents the
highest and best offer for the Sale, and the Purchase Price (as defined in the
Purchase Agreement) is fair and reasonable and provides Debtors reasonably
equivalent value for the Designated Licenses. Debtors determined to accept the
Purchaser's offer to purchase the Designated Licenses following a marketing
effort and the Auction.

         14.    The Sale has been pursued by Debtors in contemplation of their
expected reorganization, and will facilitate Debtors' attempts to reorganize
pursuant to chapter 11 of the Bankruptcy Code.

         15.    Each of the Purchase Agreement and the FCC Term Sheet and the
mutual limited releases contained in the FCC Term Sheet was negotiated, proposed
and entered into by the parties without collusion, in good faith, and from
arms'-length bargaining positions.

         16.    The Purchaser is a buyer in good faith under section 363(m) of
the Bankruptcy Code and, upon consummation of the Sale, is entitled to the
protections afforded thereby. Neither Debtors nor the Purchaser has engaged in
any conduct that would cause or permit the Purchase Agreement and the
transactions contemplated thereby to be avoided under sections 363(m) or 363(n)
of the Bankruptcy Code.

         17.    Upon FCC Regulatory Review and Approval being granted and
payment by the Purchaser of the FCC Direct Payment, the transfers of the
Designated Licenses pursuant to the Purchase Agreement (a) will be legal, valid
and effective transfers of the Rights and Interests in the Designated Licenses
to the Purchaser, and (b) will vest the Purchaser with the Rights and Interests
in the Designated Licenses, free and clear of any and all Encumbrances under
section 363(f) of the Bankruptcy Code.

         18.    Pursuant to the Purchase Agreement, Purchaser shall not be
required to close the transactions contemplated by the Purchase Agreement,
including the payment of the FCC Direct Payment, unless the closing conditions
of Article VII of the Purchase Agreement, including without limitation Section
7.3, have been fully and completely satisfied in Purchaser's sole discretion.

         19.    As indicated above, the Debtors and the FCC have reached
resolution of the FCC's claims with respect to the Designated Licenses, the
terms and conditions of which have been detailed in the FCC Term Sheet. As
further set forth in the FCC Term Sheet, the resolution also requires that the
FCC and the Debtors grant limited releases to each other from claims to the
extent (and only to the extent) that such claims relate to the Designated
Licenses. All other claims including claims in respect of the remaining,
non-Designated Licenses held by the Debtors are outside the scope of the limited
releases contained in the Agreement and are preserved and not released, subject
to a pro-rata reduction to reflect the limited releases with respect to the
proportionate value of the Designated Licenses. The proposed releases
contemplate that the FCC will receive the FCC Direct Payment free and clear of
all liens, claims and encumbrances of the Debtors or any of its creditors,
equity or other interest holders and that

the Debtors are similarly receiving the NextWave Proceeds (as defined in the FCC
Term Sheet) free and clear of any claims, liens, rights or interests of the FCC,
provided however that the FCC is not waiving its right to be heard on any matter
in the Debtors' chapter 11 cases, including but not limited to the right to
raise, appear and be heard on any proposed expenditure by the Debtors (including
from the NextWave Proceeds) outside of the ordinary course of business, and any
proceedings related to a proposed plan of reorganization. The forms of releases
to be exchanged by the Debtors and the FCC are to be binding through this Sale
Order on all of the Debtors' creditors, equity and other interest holders as set
forth in the FCC Term Sheet. Approval of the FCC Term Sheet, without
modification, by this Court in this Sale Order is a precondition to the Sale.
Further, even following entry of this Sale Order, the closing of the Sale is
conditioned upon FCC Regulatory Review and Approval and payment by the Purchaser
of the FCC Direct Payment, and in accordance with Section 3(b) of the FCC Term
Sheet, the FCC has preserved its rights and powers to take any action pursuant
to its regulatory authority over the Debtors as an FCC licensee, including
without limitation the FCC's authority under the Communications Act of 1934, as
amended, and the rules and regulations promulgated thereunder (the
"Communications Act") and the FCC rules, regulations, policies and decisions, or
with respect to any action or claim related to the Debtors' obligations
regarding the provision of notice set forth in Section 3(a) of the FCC Term
Sheet.

Grant Co., 699 F.2d 599, 608 (2d Cir. 1983), citing Newman v. Stein, 464 F.2d
689 (2d Cir. 1972); In re Ashford, 226 B.R. at 802.

         21.    The resolution articulated in the FCC Term Sheet satisfies these
standards, and represents a fair and equitable settlement which enables the
Debtors and the FCC to resolve a portion of the disputes between them without
resorting to additional litigation. The Debtors have negotiated the proposed
resolution in good faith and believe it falls within the "lowest range of
reasonableness" of the results they could have obtained in litigation, which
would have been time-consuming and expensive.

         22.    The Court has apprised itself of all facts necessary to form an
informed and objective opinion regarding the probable outcomes should the
various matters resolved by the FCC Term Sheet and the releases contained
therein be litigated. In that regard, the Court has made an educated estimate of
the complexity, expense, and likely duration of such litigation, the possible
difficulties of collecting on any judgment which might be obtained, the possible
effects such litigation may have on the ability of the Debtors to reorganize and
the viability and value of their businesses, and all other factors that are
relevant to a determination of whether the FCC Term Sheet and the releases
contained therein constitutes a full and fair compromise. See Protective
Committee for Independent Stockholders of TMT Trailer Ferry, Inc. v. Anderson,
390 U.S. 414, 424-25 (1968).

         23.    In assessing the compromise and settlement reflected by the FCC
Term Sheet and the releases contained therein, the Court has reviewed the issues
(in lieu of a trial or a mini-trial on the merits). In so doing, the Court has
given weight to the informed judgment of the Debtors, the FCC, the DIP Lenders,
and the Committee (and their respective advisors) that the compromise

and settlement reflected by the FCC Term Sheet and the releases contained
therein is fair and equitable, and considered the competency and experience of
the counsel and financial advisors who support the FCC Term Sheet.

         24.    The consummation and implementation of the FCC Term Sheet, the
terms and conditions of the FCC Term Sheet, and the mutual limited releases
contained therein are an important and necessary component of, and in
furtherance of, the Debtors' reorganization and ultimate plan of reorganization
or other distribution to the Debtors' creditors, and the parties would not have
been able to reach a settlement without agreement on the granting of the
releases. The settlement embodied in the FCC Term Sheet and the releases
provided therein are a material benefit to the Debtors', their estates, and
their creditors, equity and other interest holders. Accordingly, the FCC Term
Sheet and the releases contained therein are in the best interest of the
Debtors', their estates, and their creditors, equity and other interest holders.

         25.    Accordingly, the proposed resolution of the claims between the
FCC and the Debtors with respect to the Designated Licenses as detailed in the
FCC Term Sheet, is fair and equitable and is in the best interest of their
estates and is hereby approved.

         26.    All of the provisions of this Sale Order, the Purchase Agreement
and the FCC Term Sheet are nonseverable.

         27.    The relief requested in the Motion, including approval of the
Purchase Agreement and the FCC Term Sheet, is in the best interests of the

   IS NATIONAL IN SCOPE AND INCLUDES MOST OF THE TOP 30 METROPOLITAN MARKETS.

   ARTICLE XVII. UPON ISSUANCE OF THEIR LICENSES IN EARLY 1997, NPCI AND NPPI
EXECUTED INDIVIDUAL PROMISSORY NOTES AND SECURITY AGREEMENTS IN FAVOR OF THE FCC
                WITH RESPECT TO EACH C AND F-BLOCK PCS LICENSE.

 ARTICLE XVIII. THROUGHOUT THE BANKRUPTCY CASES, NEXTWAVE HAS WORKED TOWARD THE
GOAL OF PROVIDING WHOLESALE WIRELESS TELECOMMUNICATION SERVICES ON A NATIONWIDE
 BASIS, AND ON SEVERAL OCCASIONS HAS SOUGHT TO CONFIRM A PLAN OF REORGANIZATION
   PROVIDING SIGNIFICANT PRESENT AND FUTURE VALUE TO ITS CREDITORS AND EQUITY
 INTEREST HOLDERS - MANY OF WHOM INVESTED MONEY OR SERVICES IN NEXTWAVE IN 1996
 AND 1997. LITIGATION BETWEEN NEXTWAVE AND THE FCC ENSUED AFTER COMMENCEMENT OF
    THE BANKRUPTCY PROCEEDINGS AND THE REORGANIZATION PLANS DID NOT PROCEED.

ARTICLE XIX. FOLLOWING THE ISSUANCE OF THE UNITED STATES SUPREME COURT'S OPINION
     IN THE CASE OF FEDERAL COMMUNICATIONS COMMISSION V. NEXTWAVE PERSONAL
  COMMUNICATIONS INC., 537 U.S. 293, 123 S. CT. 832 (2003) (THE "SUPREME COURT
    OPINION") NEXTWAVE BEGAN ACTIVELY EVALUATING ALL REASONABLE OPTIONS AND
 OPPORTUNITIES FOR REORGANIZATION THAT MAXIMIZE VALUE FOR CREDITORS AND EQUITY
HOLDERS. THE DEBTORS HAVE EXPLORED MULTIPLE ALTERNATIVES IN PARALLEL, INCLUDING
  RESTRUCTURING AS A GOING CONCERN UTILIZING ALL OR SOME OF THEIR LICENSES, AS
 WELL AS OPPORTUNITIES DESIGNED TO OPTIMIZE THE USAGE AND DISPOSITION OF THEIR
    SPECTRUM ASSETS. THE DEBTORS AND THEIR INVESTMENT BANKERS AND FINANCIAL
      ADVISORS, UBS WARBURG ("UBS"), HAVE ALSO ENGAGED IN DISCUSSIONS WITH
 TELECOMMUNICATIONS CARRIERS WHO WERE BIDDERS IN AUCTION 35 THAT HAVE EXPRESSED
   AN INTEREST IN EITHER ACQUIRING CERTAIN OF THE LICENSES OR ENTERING INTO A
                 VENTURE OR OTHER TRANSACTION WITH THE DEBTORS.

   ARTICLE XX. THE DEBTORS HAVE AN OUTSTANDING DEBTOR-IN-POSSESSION LOAN (THE
 "EXISTING DIP LOAN") IN THE PRINCIPAL AMOUNT OF $200 MILLION. THE EXISTING DIP
  LOAN WAS SET TO MATURE ON JULY 30, 2003. THE DEBTORS ARE NEGOTIATING A SHORT
   EXTENSION THEREOF WITH THE DIP LENDER, AND ARE ALSO EXPLORING A POTENTIAL
REFINANCING (THE EXISTING DIP LOAN OR ANY REPLACEMENT DEBTOR-IN-POSSESSION LOAN
APPROVED BY THE BANKRUPTCY COURT ARE HEREINAFTER REFERRED TO AS THE "DIP LOAN").
   THE EXISTING DIP LOAN IS SECURED BY LIENS ON THE LICENSES OR THE PROCEEDS
 THEREOF. THE FCC HAS ALSO ASSERTED LIENS ON THE LICENSES. THE ACTUAL AMOUNT OF
                THE FCC'S CLAIM(S) AGAINST THE ESTATES OVERALL,

    AND AGAINST THE DESIGNATED LICENSES (AS DEFINED BELOW) HAS NOT YET BEEN
  DETERMINED. THE DEBTORS AND THE FCC ARE SEEKING TO CONSENSUALLY RESOLVE THE
  TOTAL AMOUNT OF THE FCC'S CLAIMS AGAINST THE ESTATES, AS WELL AS CLAIMS THE
                   DEBTORS BELIEVE THEY HAVE AGAINST THE FCC.

ARTICLE XXI. AFTER CONSULTATION WITH THE COMMITTEE, THE DEBTORS' DIP LENDER, AND
THE FCC, THE DEBTORS DETERMINED THAT A SALE OF ALL OF THEIR RIGHTS AND INTERESTS
    IN CERTAIN OF THEIR LICENSES (THE "DESIGNATED LICENSES"(1) ON THE TERMS
  DISCUSSED HEREIN OR ON SUCH HIGHER AND BETTER TERMS AS MAY BE OFFERED AT AN
 AUCTION TO BE CONDUCTED IN ACCORDANCE WITH THE BIDDING PROCEDURES (AS DEFINED
 BELOW) (THE "PROPOSED SALE"), IS IN THE BEST INTEREST OF THE DEBTORS' ESTATES
 AND WILL MAXIMIZE VALUE FOR CREDITORS AND EQUITY HOLDERS. IN CONJUNCTION WITH
  NEGOTIATING THE PROPOSED SALE, THE DEBTORS WORKED WITH THE FCC TO DEVELOP AN
 APPROACH THAT WOULD ALLOW THE PROPOSED SALE TO PROCEED, SUBJECT TO REGULATORY
APPROVAL, WHILE THE DEBTORS AND THE FCC CONTINUE TO WORK TOWARD A COMPREHENSIVE
 RESOLUTION OF THE ISSUES BETWEEN THEM. THE DEBTORS BELIEVE THAT THE RESOLUTION
    REACHED WITH THE FCC, APPROVAL OF WHICH IS SOUGHT HEREBY, IS IN THE BEST
                          INTERESTS OF THEIR ESTATES.

ARTICLE XXII. THE PROPOSED SALE DOES NOT FORECLOSE ALTERNATIVES WITH RESPECT TO
    SALE OR USE OF THE DEBTORS' REMAINING LICENSES, NOR DOES IT PRECLUDE THE
DEBTORS' REORGANIZATION. THE TRANSACTION PROPOSED HEREIN PRESERVES THE DEBTORS'
 ABILITY TO REORGANIZE THEIR BUSINESS USING THEIR REMAINING LICENSES AND/OR TO
MOVE TO SELL ADDITIONAL LICENSES AT A LATER DATE AND BY SEPARATE MOTION, AND TO
    TAKE WHATEVER OTHER ACTIONS ARE ULTIMATELY DETERMINED TO BE IN THE BEST
INTERESTS OF THE DEBTORS' ESTATES AND THAT WILL MAXIMIZE VALUE FOR ALL OF THEIR
                         CREDITORS AND EQUITY HOLDERS.

 ARTICLE XXIII. THE DEBTORS HEREBY REQUEST AUTHORITY PURSUANT TO SECTIONS 105,
 363 AND 1146 OF THE BANKRUPTCY CODE, TO SELL ALL OF THEIR RIGHTS AND INTERESTS
IN THE DESIGNATED LICENSES, FREE AND CLEAR OF ALL LIENS, CLAIMS AND ENCUMBRANCES

    ACCORDANCE WITH THE SALE PROCEDURES PROPOSED HEREIN.(2) TO FACILITATE THE
   TRANSFER OF THE DESIGNATED LICENSES, THE DEBTORS ARE CONCURRENTLY SEEKING
APPROVAL, PURSUANT TO FRBP 9019, TO RESOLVE THE AMOUNT OF THE FCC'S CLAIMS WITH
 RESPECT TO THE DESIGNATED LICENSES (THE "FCC DESIGNATED LICENSE CLAIMS"), AND
 ANY CLAIMS THE DEBTORS MAY HAVE AGAINST THE FCC WITH RESPECT TO THE DESIGNATED
 LICENSES, AS PROVIDED FOR IN THE TERM SHEET BETWEEN THE DEBTORS AND THE FCC, A
   COPY OF WHICH IS ATTACHED HERETO AS EXHIBIT B (THE "FCC TERM SHEET"). THE
   AGREEMENT AND THE FCC TERM SHEET CONTEMPLATE PAYMENT OF THE FCC DESIGNATED
    LICENSE CLAIMS THROUGH THE FCC DIRECT PAYMENT, AND THE DIP LOAN FROM THE
REMAINING PROCEEDS OF THE SALE. THE RESOLUTION OF THE CLAIMS OF THE FCC AND THE
  DEBTORS AGAINST EACH OTHER WITH RESPECT TO CLAIMS RELATED TO THE DESIGNATED
  LICENSES FURTHER CONTEMPLATES THAT THE FCC AND THE DEBTORS WILL EACH RECEIVE
LIMITED RELEASES OF SUCH DESIGNATED LICENSE CLAIMS FROM EACH OTHER AND FROM ALL
CREDITORS AND SHAREHOLDERS OF THE DEBTORS. PROCEEDING WITH THE PROPOSED SALE IS
CONTINGENT UPON APPROVAL OF THE FCC TERM SHEET. IN ADDITION, THE FCC TERM SHEET
 IS SUBJECT TO APPROVAL OF THE UNITED STATES DEPARTMENT OF JUSTICE (THE "DOJ").
 IF THE DOJ HAS NOT APPROVED THE FCC TERM SHEET BY THE INITIAL HEARING DATE SET
FOR THIS MOTION, THE HEARING ON THE MOTION WILL BE CONTINUED IF THERE IS BEEN NO
   DECISION BY THE DOJ BY SUCH DATE, OR IF SUCH APPROVAL WAS NOT OBTAINED THE
                  MOTION WILL BE WITHDRAWN WITHOUT PREJUDICE.

         "best." In re Brakalis, 220 B.R. 525, 533 (Bankr. S.D. N.Y. 1998). "[A
         debtor's] duty to maximize the return to a bankruptcy estate often does
         not require recommendation of the highest monetary bid." Id. (citing In
         re Gil-Bern Indus., Inc., 526 F.2d 627, 629 (1st Cir. 1975)) As such,
         nothing herein, including any reference to "highest and best" offer,
         shall be construed to limit the Debtors' business judgment as it
         pertains to selecting the bid, of which the Debtors will seek Court
         approval.

                           "Break-up Fee") to the Proposed Purchaser out of the
                           proceeds of a Winning Bid or Competing Proposal if a

     THE LIONEL CASE, HAS ESSENTIALLY BECOME THE GUIDEPOST FOR ASSET SALES:

         The history surrounding the enactment in 1978 of current
         Chapter 11 and the logic underlying it buttress our
         conclusion that there must be some articulated business
         justification, other than appeasement of major creditors, for
         using, selling or leasing property out of the ordinary course
         of business before the bankruptcy judge may order such
         disposition under section 363(b).

                                       ***

         The rule we adopt requires that a judge determining a
         ss.363(b) application expressly find from the evidence
         presented before him at the hearing a good business reason to
         grant such an application.

 ARTICLE XXIX. IT HAS GENERALLY BEEN DETERMINED AND ACCEPTED THAT A SALE OUT OF
THE ORDINARY COURSE OF BUSINESS PURSUANT TO SECTION 363(B)(1) OF THE BANKRUPTCY
  CODE WILL BE APPROVED IF (I) THE SALE IS SUPPORTED BY THE DEBTOR'S BUSINESS
    JUDGMENT, (II) THE SALE PRICE IS FAIR AND REASONABLE, (III) ADEQUATE AND
   REASONABLE NOTICE HAS BEEN PROVIDED, AND (IV) THE TRANSFER IS MADE IN GOOD
   FAITH. IN RE APEX OIL CO., 92 B.R. 847, 866 (BANKR. E.D. MO. 1988) (CITING
 CASES); IN RE PHOENIX STEEL CORP., 82 B.R. 334, 335-36 (BANKR. D. DEL. 1987).

ARTICLE XXX. A COURT SHOULD NOT SECOND-GUESS A DEBTOR'S BUSINESS JUDGMENT UNLESS
THE JUDGMENT IS CLEARLY ERRONEOUS, TOO SPECULATIVE OR CONTRARY TO THE PROVISIONS
OF THE BANKRUPTCY CODE. "MORE EXACTING SCRUTINY WOULD SLOW THE ADMINISTRATION OF
THE DEBTOR'S ESTATE AND INCREASE ITS COST, INTERFERE WITH THE BANKRUPTCY CODE'S
PROVISION FOR PRIVATE CONTROL OF ADMINISTRATION OF THE ESTATE, AND THREATEN THE
COURT'S ABILITY TO CONTROL A CASE IMPARTIALLY." RICHMOND LEASING CO. V. CAPITAL
                BANK, N.A., 762 F.2D 1303, 1311 (5TH CIR. 1985).

  ARTICLE XXXI. SUBJECT TO COMPLIANCE WITH THE BIDDING PROCEDURES, THE DEBTORS
 RESPECTFULLY SUBMIT THAT THESE ELEMENTS HAVE ALL BEEN SATISFIED IN THE INSTANT
                                     CASE.

                  31.1     Business Judgment, Sale Price and Good Faith.

  ARTICLE XXXII. THE DECISION TO SELL THE DEBTORS' RIGHTS AND INTERESTS IN THE
DESIGNATED LICENSES IN ACCORDANCE WITH THE TERMS AND CONDITIONS OF THE AGREEMENT
   WAS MADE THROUGH AN EXERCISE OF THE DEBTORS' SOUND BUSINESS JUDGMENT. THE
 DEBTORS HAVE DETERMINED, AS A RESULT OF THEIR ASSET VALUE MAXIMIZATION EFFORTS
 AND THEIR REORGANIZATION RESTRUCTURING GOALS, THAT THE CONTINUED OPERATION AND
HOLDING OF THE DESIGNATED LICENSES IS NOT NECESSARY FOR THE DEBTORS TO COMPLETE
THEIR REORGANIZATION. BY SELLING THEIR INTEREST IN THE DESIGNATED LICENSES, THE
  DEBTORS WILL GENERATE CASH SUFFICIENT TO SATISFY THE FCC DESIGNATED LICENSE
 CLAIMS AND THE DIP LOAN, WHILE LEAVING MORE THAN $460 MILLION IN THE DEBTORS'
    ESTATES WHICH CAN BE DEVOTED TO THEIR REORGANIZATION. THE PURCHASE PRICE
 PROVIDED IN THE AGREEMENT REPRESENTS THE BEST OFFER RECEIVED BY THE DEBTORS TO
 DATE. THE DEBTORS BELIEVE THAT THE PURCHASE PRICE REPRESENTS FAIR MARKET VALUE
 FOR THE DESIGNATED LICENSES AND THAT THE AGREEMENT IS THE CULMINATION OF GOOD
FAITH, ARMS' LENGTH NEGOTIATIONS BETWEEN THE DEBTORS AND PROPOSED PURCHASER AND
  IS NOT IN VIOLATION OF SECTION 363(N) OF THE BANKRUPTCY CODE. THEREFORE, THE
                                 PROPOSED SALE

                  (4)      such interest is in bona fide dispute; or

                  (5)      such entity could be compelled, in a legal or
                           equitable proceeding, to accept a money satisfaction
                           of such interests.

                  11 U.S.C. ss. 363(f). The Debtors submit that the requirements
set forth in Section 363(f) of the Bankruptcy Code are satisfied and, therefore,
the Court is authorized to grant the relief requested.

                  35.1     Transfer Taxes.

         Section 1146(c) of the Bankruptcy Code provides that:

                  [t]he issuance, transfer, or exchange of a security,
                  or the making or delivery of an instrument of
                  transfer under a plan confirmed under section 1129
                  of this title, may not be taxed under any law
                  imposing a stamp or similar tax.

                  11 U.S.C. ss. 1146(c). Section 105(a) of the Bankruptcy Code
provides that:

                  [t]he court may issue any order, process or judgment
                  that is necessary or appropriate to carry out the
                  provisions of this title. No provisions of this
                  title providing for the raising of an issue by a
                  party in interest shall be construed to preclude the
                  court from sua sponte, taking any action or making
                  any determination necessary or appropriate to
                  enforce or implement court orders or rules, or to
                  prevent an abuse of process.

                  11 U.S.C. ss. 105(a).

   ARTICLE XXXVI. CONSISTENT WITH SECTION 105(A) OF THE BANKRUPTCY CODE, THE
 EXEMPTION FROM "STAMP OR SIMILAR TAXES" PROVIDED UNDER SECTION 1146(C) OF THE
  BANKRUPTCY CODE, HAS BEEN BROADLY CONSTRUED BY BANKRUPTCY COURTS TO INCLUDE
ASSET SALES AND TRANSFERS THAT OCCUR PRIOR TO CONFIRMATION OF A CHAPTER 11 PLAN.
 THE TERM "STAMP OR SIMILAR TAXES" INCLUDES TRANSFER TAXES. SEE IN RE 995 FIFTH
    AVENUE ASSOCS., 963 F.2D 503, 501-11 (2D CIR. 1992). CONSISTENT WITH THE
FOREGOING, THE DEBTORS REQUEST THE SALE CONTEMPLATED BY THE AGREEMENT BE EXEMPT
       FROM TRANSFER TAXES UNDER SECTION 1146(C) OF THE BANKRUPTCY CODE.

  ARTICLE XXXVII. SECTION 105(A) OF THE BANKRUPTCY CODE EMPOWERS THE COURT TO
  "[I]SSUE ANY ORDER, PROCESS OR JUDGMENT THAT IS NECESSARY OR APPROPRIATE TO
 CARRY OUT THE PROVISIONS OF [TITLE 11]." 11 U.S.C. SS. 105. UNDER SECTION 105,
  THE COURT CAN PERMIT PRE-PLAN PAYMENT OF A PREPETITION OBLIGATION. ALTHOUGH
  CERTAIN COURTS HAVE FOUND THAT SECTION 105 "MAY NOT BE USED AS A VEHICLE TO
  DISCRIMINATE AMONG PRIORITY CLAIMS WHEN THERE IS NO COMPELLING BUSINESS NEED
  FOR SUCH DISCRIMINATION," IN RE NVR L.P., 147 B.R. 126, 127 (BANKR. E.D. VA.
      1992), SUCH ARGUMENT IS NOT APPLICABLE TO THE INSTANT CASE IN WHICH
    SECTION 507 DOES NOT TRULY ADDRESS PRIORITIES OF PAYMENT WITH REGARD TO
     SECURED CLAIMS. AS THE COURT STATED IN IN RE CHATEAUGAY CORP., 80 B.R.
                           279, 287 (S.D. N.Y. 1987):

         A rigid application of the priorities of ss. 507 would be
         inconsistent with the fundamental purpose of reorganization
         and of the Act's grant of equity powers to bankruptcy courts,
         which is to create a flexible mechanism that will permit the
         greatest likelihood of survival of the debtor and payment of
         creditors in full or at least proportionately. The Supreme
         Court has emphasized the special nature of reorganization
         proceedings.

                  It is a special proceeding which seeks
                  only to bring about a reorganization, if a
                  satisfactory plan to that end can be
                  devised and to prevent the attainment of
                  that object is to defeat the very end the
                  accomplishment of which was the sole aim
                  of the section, and thereby to render its
                  provisions futile.

                  (citing Continental Illinois Nat'l Bank & Trust Co. v.
Chicago, Rock Island & Pacific Hwy., 294 U.S. 648, 676 (1935)).

  ARTICLE XXXVIII. THE DEBTORS SEEK HEREIN TO HAVE THE FCC DESIGNATED LICENSE
   CLAIMS PAID THROUGH THE FCC DIRECT PAYMENT AND THE DIP LOAN PAID FROM THE
REMAINING PROCEEDS OF THE PROPOSED SALE. THE DEBTORS SUBMIT THAT THE PAYMENT OF
SUCH INDEBTEDNESS IS APPROPRIATE IN THIS CASE AS THE DIP LENDER AND THE FCC EACH
  CLAIM LIENS ON ALL THE DESIGNATED LICENSES AND SUCH LIENS, IF ALLOWED, WOULD
            FOLLOW THE PROCEEDS FROM THE PROPOSED SALE IN ANY EVENT.

                  38.1     Bidding Procedures.

 ARTICLE XXXIX. THE PURPOSE OF ESTABLISHING BIDDING PROCEDURES IS TO FACILITATE
 AN OPEN AND FAIR SALE IN AN EFFORT TO MAXIMIZE THE VALUE FOR THE ESTATE. IN RE
 EDWARDS, 228 B.R. 552, 561 (BANKR. E.D. PA. 1998). FURTHER, BIDDING PROCEDURES
                     PROPOSED BY A DEBTOR-IN-POSSESSION ARE

                           in writing, its Bid to the Debtors' through their
                           undersigned counsel and financial advisor at their
                           respective specified addresses such that the Bid is
                           actually received by each of the foregoing persons
                           not later than 12:00 p.m. (Eastern time) on September
                           15, 2003 (the "Bid Deadline").

                  -        To be considered, a "Bid" must consist of the
                           following:

                  -        The Qualified Bidder offers to purchase the Debtors'

                           Licenses or 30 days after the entry of the Sale Order

                           Bid will be valued based upon factors such as net
                           value provided by such bid and the likelihood and
                           timing of consummation.

                           professionals. Debtors may request additional
                           information from a bidder other than Proposed
                           Purchaser (whether previously qualified or not) in
                           order to evaluate the bidder's ability to consummate
                           a transaction and to fulfill its obligations in
                           connection therewith, and such bidder shall be
                           obligated to provide such information as a
                           precondition to participating further in the Auction.

                  -        Only Qualified Bids shall be considered at the
                           Auction. The Auction shall be conducted by the
                           Debtors or their representatives and shall commence
                           on September 23, 2003, at 9 o'clock a.m. at the
                           offices of UBS located at 299 Park Avenue, New York,
                           New York 10171.

                  -        If at least one Qualified Bid has been received (the
                           "Topping Bid"), the Debtors may conduct an Auction in
                           accordance with the terms below. Only Qualified
                           Bidders (including the Proposed Purchaser) will be
                           eligible to participate at the Auction. At least two
                           (2) business days prior to the Auction, each
                           Qualified Bidder (including the Proposed Purchaser or
                           its Affiliates, any of which is deemed a Qualified
                           Bidder) who has submitted a Qualified Bid must inform
                           the Debtors whether it intends to participate.

                  -        At the Auction, only the Proposed Purchaser and such
                           Qualified Bidders who have submitted Qualified Bids
                           in attendance at the start of the Auction shall be
                           entitled to make any additional bids. The additional
                           bids will be made and received in one room, on an
                           open basis, and all other bidders shall be entitled
                           to be present for all bidding with the understanding
                           that the true identity of each bidder (including such
                           bidder's ultimate parent) shall be fully disclosed to
                           all other bidders and that all material terms of each
                           bid will be fully disclosed to all other bidders
                           throughout the entire Auction.

                  -        At the Auction, all increases in bids following
                           receipt of a bid in the amount of the Overbid
                           Threshold shall be made in increments of no less than
                           $10 million with the Proposed Purchaser receiving
                           credit for the Break-Up Fee. Bidding at the Auction
                           shall continue until such time as the highest and
                           best offer is determined. For the avoidance of doubt,
                           during the Auction, in order for an additional bid by
                           the Proposed Purchaser or any of its Affiliates to
                           top the Topping Bid or any other additional bid
                           (other than its own), the Proposed Purchaser's
                           additional bid (or the additional bid of any
                           Affiliate of the Proposed Purchaser) shall be not
                           less than $10 million greater than the Topping Bid or
                           any other subsequent bid less $21 million.

                           determine to be the highest and best offer for the
                           Licenses (the "Winning Bid"). Debtors shall file a
                           notice with the Court of such election and present
                           the Winning Bid to the Court for approval. The party
                           that submits the Winning Bid shall be referred to as
                           the "Winning Bidder"). Unless and to the extent
                           otherwise agreed to by the Debtors, the Winning
                           Bidder will enter into a definitive agreement before
                           the Auction is adjourned. No offer shall be deemed
                           accepted unless and until it is approved by the
                           Bankruptcy Court.

                  -        Within 30 business days after a Winning Bid has been
                           selected and the Proposed Sale of the Designated
                           Licenses has been approved by the Court, the Earnest
                           Money Deposits of the Qualified Bidders who are not
                           the Winning Bidder shall be returned, provided such
                           Qualified Bidder has not appealed from the order
                           approving the Proposed Sale of the Designated
                           Licenses.

                  -        The Debtors shall apply the deposit of the Winning
                           Bidder to the Purchase Price at the Closing.

                  -        In the event a bidder submitting a Qualified Bid or
                           Competing Proposal is accepted following the
                           conclusion of the Auction (as determined by the
                           Debtors and the Court), and such high bidder fails to
                           consummate the proposed transaction by the Closing
                           Date due to a breach by such high bidder, the deposit
                           shall be forfeited to the Debtors (but not as
                           liquidated damages, the Debtors herein reserving the
                           right to pursue all remedies that may be available to
                           them), and the Debtors may consummate the proposed
                           transaction with the next highest bidder at the final
                           price bid by such bidder at the Auction (or, if such
                           bidder is unable to consummate the transaction at
                           such price, the Debtors may consummate the
                           transaction with the next highest bidder, and so
                           forth), all at the Debtors' option (i.e., the Debtors
                           are not obligated to take the next highest bid). The
                           agreement with the highest bidder shall be deemed in
                           full force and effect through the Closing Date.

                  -        The Bidding Procedures Order shall provide that the
                           Sale is contingent upon the approval of the FCC Term
                           Sheet without modification and that the Sale will not
                           proceed without such approval.

 THE ESTATE. IN RE BIDERMANN INDUS., 203 B.R. 547, 553 (BANKR. S.D. N.Y. 1997).
  THE DEBTORS SUBMIT THAT THE FOREGOING BIDDING PROCEDURES PROVIDE A FAIR AND
 REASONABLE MEANS OF ENSURING THE DEBTORS' INTEREST IN THE DESIGNATED LICENSES
   ARE SOLD FOR THE HIGHEST AND BEST OFFER OBTAINABLE. SUCH PROCEDURES AFFORD
  POTENTIAL PURCHASERS A REASONABLE OPPORTUNITY TO INVESTIGATE THE DESIGNATED
  LICENSES AND AFFORD THE DEBTORS REQUISITE TIME TO CONSIDER AND EVALUATE ANY
   QUALIFIED BIDS SUBMITTED. BASED UPON THE FOREGOING, THE DEBTORS SUBMIT THE
BIDDING PROCEDURES ARE IN THE BEST INTERESTS OF THE DEBTORS' ESTATES AND SHOULD
                                  BE APPROVED.

                  42.1     The Proposed Break-Up Fee and Expense Reimbursement.

 ARTICLE XLIII. THE DEBTORS ALSO REQUEST APPROVAL, PURSUANT TO SECTIONS 105(A)
AND 363(B) OF THE BANKRUPTCY CODE, OF THE PROPOSED BREAK-UP FEE OF $21 MILLION,
REPRESENTING ONE AND ONE-HALF PERCENT (1.5%) OF THE PURCHASE PRICE, WHICH WOULD
   BE PAYABLE BY THE DEBTORS TO THE PROPOSED PURCHASER FROM THE PROCEEDS OF A
    WINNING BID OR COMPETING PROPOSAL FOR AN ALTERNATIVE TRANSACTION THAT IS
 APPROVED BY THE BANKRUPTCY COURT AND CONSUMMATED. AS A STALKING HORSE BIDDER,
  THE PROPOSED PURCHASER HAS ESTABLISHED A GUARANTEED RETURN FOR THE DEBTORS'
  ESTATES AND CREDITORS. EVEN IF THE PROPOSED PURCHASER ULTIMATELY IS NOT THE
 SUCCESSFUL BIDDER, THE DEBTORS AND THEIR ESTATES WILL HAVE BENEFITED FROM THE
  HIGHER PURCHASE PRICE ESTABLISHED BY THE IMPROVED BID. THE PROPOSED BIDDING
PROCEDURES REQUIRE THAT IN ORDER TO QUALIFY, QUALIFIED BIDS EXCEED THE PURCHASE
     PRICE BY A MINIMUM OF $61 MILLION. THUS, IF AN ALTERNATIVE TRANSACTION
 ULTIMATELY IS APPROVED AND CONSUMMATED, THE BREAK-UP FEE WILL ONLY BE PAYABLE
  AFTER THE SALE PROCEEDS HAVE BEEN RECEIVED BY THE DEBTORS' ESTATES AND FROM
AMOUNTS THAT ARE IN EXCESS OF THE PURCHASE PRICE. CONSEQUENTLY, THERE WILL BE NO
 DIMINUTION IN VALUE TO THE DEBTORS' ESTATES IF THE BREAK-UP FEE IS ULTIMATELY
                                     PAID.

 ARTICLE XLIV. IN ADDITION TO THE BREAK-UP FEE, DEBTORS HAVE AGREED TO PAY THE
PROPOSED PURCHASER AN EXPENSE REIMBURSEMENT NOT TO EXCEED $400,000 IN THE EVENT
  THE AGREEMENT IS TERMINATED (I) AS A RESULT OF BREACH BY DEBTORS; (II) AS A
   RESULT OF AN ORDER HAVING BEEN ENTERED PROHIBITING THE TRANSACTION; (III)
BECAUSE DEBTORS' BANKRUPTCY CASES ARE DISMISSED OR CONVERTED AND AS A RESULT OF
SUCH DISMISSAL OR CONVERSION THE PROPOSED SALE IS NOT CONSUMMATED; (IV) BECAUSE
     THE SALE ORDER IS NOT ENTERED BY OCTOBER 17, 2003; OR (V) BECAUSE THE

    CLOSING DOES NOT OCCUR BY JANUARY 31, 2003 (UNLESS SUCH DATE IS EXTENDED
                          PURSUANT TO THE AGREEMENT).

     ARTICLE XLV. IN THE NON-BANKRUPTCY CONTEXT, BREAK-UP FEES AND EXPENSE
  REIMBURSEMENTS ARE COMMON IN CORPORATE TRANSACTIONS. SEE, E.G., IN RE WINTZ
COMPANIES, 230 B.R. 840, 846 (B.A.P. 8TH CIR. 1999); IN RE INTEGRATED RESOURCES,
   INC., 135 B.R. 736, 750 (BANKR. S.D. N.Y.), AFF'D, 147 B.R. 650 (S.D. N.Y.
   1992). COURTS IN THIS DISTRICT RECOGNIZE THAT MANY OF THE SAME REASONS FOR
 GRANTING BREAK-UP FEES AND EXPENSE REIMBURSEMENTS IN NON-BANKRUPTCY CORPORATE
  TRANSACTIONS APPLY IN THE BANKRUPTCY CONTEXT AS WELL. FOR EXAMPLE, IN IN RE
 INTEGRATED RESOURCES, THE COURT NOTED THAT "[I]N ORDER TO ENCOURAGE THE MAKING
 OF BIDS, DEBTORS ENTICE POTENTIAL PURCHASERS BY UTILIZING VARIOUS INCENTIVES,
   SUCH AS BREAK-UP FEES, TOPPING FEES AND EXPENSE REIMBURSEMENT AGREEMENTS."
                     INTEGRATED RESOURCES, 135 B.R. AT 750.

 ARTICLE XLVI. OTHER COURTS IN THIS DISTRICT HAVE NOTED THAT BREAK-UP FEES ARE
OFTEN "LEGITIMATELY NECESSARY" IN TRANSACTIONS TO CONVINCE A "STALKING HORSE" TO
  ENTER THE BIDDING BY PROVIDING SOME FORM OF COMPENSATION FOR THE RISK IT IS
  UNDERTAKING. IN RE 995 FIFTH AVE. ASSOCS., L.P., 96 B.R. 24, 28 (BANKR. S.D.
                                  N.Y. 1989).

   ARTICLE XLVII. BREAK-UP FEES AND EXPENSE REIMBURSEMENTS ARE PRESUMPTIVELY
APPROPRIATE UNDER THE BUSINESS JUDGMENT RULE, AND WILL GENERALLY BE SUSTAINED SO
 LONG AS THE FEE IS NOT SO LARGE THAT IT CHILLS THE BIDDING PROCESS. INTEGRATED
 RESOURCES, 135 B.R. AT 750. STATED SLIGHTLY DIFFERENTLY, "[W]HEN REASONABLE IN
   RELATION TO THE BIDDER'S EFFORTS AND TO THE MAGNITUDE OF THE TRANSACTION,
BREAK-UP FEES ARE GENERALLY PERMISSIBLE." 995 FIFTH AVE., 96 B.R. AT 28 (CITING
 COTTLE V. STORER COMMUNICATION, INC., 849 F.2D 570, 578 (11TH CIR. 1988)).(4)

 ARTICLE XLVIII. THE PROPOSED BIDDING PROTECTIONS MEET THE "BUSINESS JUDGMENT"
  RULE STANDARD. THE BREAK-UP FEE AND THE EXPENSE REIMBURSEMENT ARE REASONABLE
 BECAUSE THEY ARE NOT EXCESSIVE COMPARED TO FEES AND REIMBURSEMENTS APPROVED IN
OTHER CASES IN THIS CIRCUIT. IN ADDITION, THE BREAK-UP FEE WILL NOT DIMINISH THE
                                    DEBTORS'

---------------
(4)      In approving a $500,000 to $9 million graduated break-up fee plus
         expense reimbursement, the Integrated Resources court noted that
         break-up fees have been approved by bankruptcy courts in this district
         in numerous cases (discussing: 995 Fifth Ave., 96 B.R. at 28 ($500,000
         break-up fees approved after sale of $76 million hotel); In re
         Crowthers McCall Pattern, Inc., 115 B.R. 877, 879 (Bankr. S.D. N.Y.)
         (1990) ($500,000 break-up fee on a $45 million sale); In re T.V.S.I.
         Holdings, Inc., et al., Nos. 90B 13581-13586, 90B 13586-13864 (CB)
         (Bankr. S.D. N.Y. 1991) ($3.5 million break-up fee in transaction

         assumption of pre- and post-petition obligations of Debtor)).

THE DEBTOR BELIEVES IS FAIR AND REASONABLE, WHILE PROVIDING THE DEBTOR WITH THE
  OPPORTUNITY OF OBTAINING EVEN GREATER BENEFITS FOR THE ESTATE THROUGH A SALE
                                    PROCESS.

 ARTICLE XLIX. ACCORDINGLY, THE DEBTORS REQUEST THAT THE COURT APPROVE (I) THE
BREAK-UP FEE, (II) THE EXPENSE REIMBURSEMENT, AND (III) THE PROPOSED FORM OF THE
 BIDDING PROCEDURES ORDER, INCLUDING THE PROVISION THAT ENTRY OF THE SALE ORDER
   IS CONDITIONED UPON APPROVAL OF THE FCC TERM SHEET, WITHOUT MODIFICATION.

         49.1     FCC Claim Resolution and Exchange of Limited Mutual Releases.

 ARTICLE L. AS INDICATED ABOVE, THE DEBTORS AND THE FCC HAVE REACHED RESOLUTION
  OF THE FCC'S CLAIMS WITH RESPECT TO THE DESIGNATED LICENSES. THE RESOLUTION
 PROVIDES THAT THE FCC WILL RECEIVE A MINIMUM OF $714 MILLION DIRECTLY FROM THE
PROPOSED PURCHASER (OR OTHER WINNING BIDDER) IN FULL SATISFACTION OF ANY CLAIMS
   THE FCC MAY HAVE AGAINST THE DEBTORS OR THEIR ESTATES WITH RESPECT TO THE
 DESIGNATED LICENSES. THE RESOLUTION FURTHER PROVIDES THAT AFTER FUNDING OF THE
   INDEMNITY ESCROW OF $20 MILLION, THE REMAINING PROCEEDS (A MINIMUM OF $666
  MILLION WITHOUT ACCOUNTING FOR THE POTENTIAL OF ANY HIGHER OR BETTER OFFERS)
  (THE "NEXTWAVE PROCEEDS") SHALL BE PROPERTY OF THE DEBTORS' ESTATES FREE AND
CLEAR OF ANY LIENS, CLAIMS, ENCUMBRANCES, RIGHTS OR INTERESTS OF THE FCC. TO THE
    EXTENT THE INDEMNITY PROCEEDS ARE RELEASED PURSUANT TO THE TERMS OF THE
AGREEMENT, THEY WILL SIMILARLY BECOME NEXTWAVE PROCEEDS. FURTHER, TO THE EXTENT
    THAT THE AUCTION RESULTS IN APPROVAL OF A WINNING BID FOR THE DESIGNATED
LICENSES OF MORE THAN $1.5 BILLION (THE INCREMENTAL $100 MILLION BECOME NEXTWAVE
PROCEEDS), THE FCC DIRECT PAYMENT WILL BE INCREASED BY 34% OF AMOUNTS OVER $1.5
 BILLION UP TO A MAXIMUM FCC DIRECT PAYMENT OF $734 MILLION FOR THE DESIGNATED
LICENSES. AS SET FORTH IN THE FCC TERM SHEET, THE RESOLUTION ALSO REQUIRES THAT
  THE FCC AND NEXTWAVE GRANT LIMITED RELEASES TO EACH OTHER FROM CLAIMS TO THE
   EXTENT (AND ONLY TO THE EXTENT) THAT SUCH CLAIMS RELATE TO THE DESIGNATED
 LICENSES. ALL CLAIMS IN RESPECT OF THE REMAINING, NON-DESIGNATED LICENSES HELD
   BY NEXTWAVE ARE OUTSIDE THE SCOPE OF THE LIMITED RELEASES CONTAINED IN THE
AGREEMENT AND ARE PRESERVED AND NOT RELEASED, SUBJECT TO A PRO-RATA REDUCTION IN

   ALL LIENS, CLAIMS AND ENCUMBRANCES OF NEXTWAVE OR ANY OF ITS CREDITORS OR
INTEREST HOLDERS AND THAT NEXTWAVE IS SIMILARLY RECEIVING THE NEXTWAVE PROCEEDS
 FREE AND CLEAR OF ANY CLAIMS, LIENS, RIGHTS OR INTERESTS OF THE FCC. THE FORMS
 OF RELEASES TO BE EXCHANGED BY NEXTWAVE AND THE FCC AND TO BE BINDING THROUGH
  THE SALE ORDER ON ALL NEXTWAVE CREDITORS AND EQUITY INTEREST HOLDERS ARE SET
  FORTH IN THE FCC TERM SHEET AND IN THE PROPOSED FORM OF SALE ORDER ATTACHED
HERETO AS EXHIBIT "E." APPROVAL OF THE FCC TERM SHEET, WITHOUT MODIFICATION, IS
A PRECONDITION TO THE SALE PROCEEDING. FURTHER, EVEN FOLLOWING ENTRY OF THE SALE
     ORDER, THE CLOSING IS CONDITIONED UPON FCC REGULATORY APPROVAL OF THE
APPLICATIONS FOR ASSIGNMENT OF THE DESIGNATED LICENSES. IN ADDITION, THE FCC AND
    THE DOJ HAVE PRESERVED THEIR RIGHTS WITH RESPECT TO FEDERAL TAXES OR THE
   ENFORCEMENT OF THE CRIMINAL, ENVIRONMENTAL OR ANTITRUST LAWS OF THE UNITED
  STATES, OR WITH RESPECT TO ANY ACTION BY THE FCC PURSUANT TO ITS REGULATORY
AUTHORITY OVER THE DEBTORS AS AN FCC LICENSEE, INCLUDING WITHOUT LIMITATION ITS
AUTHORITY UNDER THE COMMUNICATIONS ACT AND THE FCC RULES, REGULATIONS, POLICIES
 AND DECISIONS, OR WITH RESPECT TO ANY ACTION OR CLAIM RELATED TO THE DEBTORS'
COVENANT REGARDING THE PROVISION OF NOTICE SET FORTH IN SECTION 3(A) OF THE FCC
                                  TERM SHEET.

 ARTICLE LI. FEDERAL RULE OF BANKRUPTCY PROCEDURE 9019(A) AUTHORIZES A COURT TO
   APPROVE A COMPROMISE OR SETTLEMENT WHEN IT IS IN THE BEST INTERESTS OF THE
 ESTATE. IN RE ASHFORD MOTELS, LTD., 226 B.R. 797, 802 (BANKR. S.D.N.Y. 1998).
 THE COURT SHOULD APPROVE THE SETTLEMENT WHEN IT MEETS THE LOWEST POINT IN THE
 RANGE OF REASONABLENESS. ID. IN MAKING SUCH A DETERMINATION, THE COURT SHOULD
                        CONSIDER THE FOLLOWING FACTORS:

         (1) The balance between the likelihood of the plaintiff or
         the defendant's success should the case go to trial as
         compared with the benefits of the settlement without the
         expense and delay of a trial;

         (2) The prospect of a complex and protracted litigation if
         the settlement is not approved;

         (3) The proportion of the creditors who do not object to, or
         who affirmatively support, the proposed settlement;

         (4) The proposed benefits to be received;

         (5) The nature and breadth of releases to be issued as a
         result of the settlement; and

         (6) The extent to which the settlement is truly the product
         of arms' length bargaining and not the product of fraud or
         collusion.

N.Y. 1994); In re Fugazy, 150 B.R. 103, 106 (Bankr. S.D. N.Y. 1993)).

   ARTICLE LII. THE RESOLUTION BETWEEN THE FCC AND THE DEBTORS SATISFIES THIS
STANDARD. THE RESOLUTION ENABLES THE DEBTORS AND THE FCC TO RESOLVE A PORTION OF
   THE DISPUTES BETWEEN THEM WITHOUT RESORTING TO ADDITIONAL LITIGATION. THE
  DEBTORS HAVE NEGOTIATED THE PROPOSED RESOLUTION IN GOOD FAITH AND BELIEVE IT
FALLS WITHIN THE "LOWEST RANGE OF REASONABLENESS" OF THE RESULTS THEY COULD HAVE
  OBTAINED IN LITIGATION, WHICH WOULD HAVE BEEN TIME-CONSUMING AND EXPENSIVE.
ACCORDINGLY, THE DEBTORS RESPECTFULLY SUBMIT THAT THE PROPOSED RESOLUTION OF THE
 CLAIMS BETWEEN THE FCC AND THE DEBTORS WITH RESPECT TO THE DESIGNATED LICENSES
        IS IN THE BEST INTEREST OF THEIR ESTATES AND SHOULD BE APPROVED.

 ARTICLE LIII. AS DISCUSSED ABOVE, THE TERMS OF THE RESOLUTION BETWEEN THE FCC
  AND NEXTWAVE ADDITIONALLY CONTEMPLATE THAT THE FCC WILL RECEIVE THIRD PARTY
RELEASES FROM ALL OTHER CREDITORS AND EQUITY OR OTHER INTEREST HOLDERS IN THESE
 CHAPTER 11 CASES WITH RESPECT TO CLAIMS, CAUSES OF ACTION, ETC. IN RESPECT OF
THE DESIGNATED LICENSES. ESSENTIALLY, THE LIMITED RELEASE OF THE FCC BY NEXTWAVE
DESCRIBED ABOVE WILL ALSO BE APPLICABLE TO ALL NEXTWAVE CREDITORS AND EQUITY OR
OTHER INTEREST HOLDERS WHO MIGHT HAVE, OR BELIEVE THEY MIGHT HAVE CLAIMS AGAINST
                  THE FCC RELATED TO THE DESIGNATED LICENSES.

  ARTICLE LIV. THERE IS A FAIRLY WELL-DEFINED BODY OF CASE LAW REGARDING THIRD
PARTY RELEASES UNDER A CHAPTER 11 PLAN OF REORGANIZATION. HOWEVER, THE NUMBER OF
PUBLISHED OPINIONS RELATING TO THIRD PARTY RELEASES IN THE SETTLEMENT CONTEXT IS
    MORE LIMITED. TWO OF THE LEADING CASES ON THIS POINT, MUNFORD OUT OF THE
 ELEVENTH CIRCUIT AND MONARCH LIFE INSURANCE OUT OF THE FIRST CIRCUIT, SUPPORT
   THE BANKRUPTCY COURT'S ABILITY TO ISSUE THIRD PARTY RELEASES AS PART OF A
      SETTLEMENT.(5) UNDER THE CIRCUMSTANCES OF THESE CHAPTER 11 CASES, AS

---------------
(5)      The Zale case out of the Fifth Circuit came to a different conclusion,
         but is distinguishable, see paragraphs 55-57 supra.

 WELL AS UNDER DREXEL AND ITS PROGENY IN THIS CIRCUIT, THE DEBTORS RESPECTFULLY
SUBMIT THAT THE THIRD PARTY RELEASES CALLED FOR BY THE AGREEMENT AND RESOLUTION
   WITH THE FCC ARE JUSTIFIED AND APPROPRIATE, CONSISTENT WITH SECOND CIRCUIT
       PRECEDENT AND PUBLIC POLICY, AND SHOULD BE APPROVED BY THE COURT.

   ARTICLE LV. IN MUNFORD V. MUNFORD, INC., 97 F.3D 449 (11TH CIR. 1996), THE
   ELEVENTH CIRCUIT WAS FACED WITH AN APPEAL FROM A LOWER COURT'S ORDER WHICH
BARRED NON-SETTLING DEFENDANTS FROM ASSERTING CONTRIBUTION AND INDEMNITY CLAIMS
 AGAINST VRC, ONE OF THE OTHER DEFENDANTS IN THE LITIGATION. UNDER THE TERMS OF
THE PROPOSED SETTLEMENT, VRC WAS TO PAY $350,000 TO THE ESTATE, BUT SUCH PAYMENT
WAS CONDITIONED UPON BARRING THE OTHER DEFENDANTS FROM SUING VRC UNDER STATE LAW
CONTRIBUTION AND INDEMNITY THEORIES OF RECOVERY. IN AFFIRMING THE LOWER COURT'S
 RULING AND HOLDING THE THIRD PARTY RELEASES TO BE VALID, THE ELEVENTH CIRCUIT
  FOUND THAT THE RELEASES NOT ONLY SERVED THE PUBLIC POLICY OF SETTLEMENT OVER
 LITIGATION, BUT ALSO HAD A DIRECT IMPACT ON AND NEXUS TO THE ESTATE - I.E., IF
  NO THIRD PARTY RELEASES THEN NO MONEY FOR THE ESTATE, AND POSSIBLY YEARS OF
 CONTINUED LITIGATION. THUS, ACCORDING TO THE ELEVENTH CIRCUIT, SECTION 105(A)
     AND RULE 16 OF THE FEDERAL RULES OF CIVIL PROCEDURE MAY BE USED BY THE
  BANKRUPTCY COURT TO FASHION ORDERS INTEGRAL TO SETTLEMENTS. SEE ALSO MONARCH
LIFE INS. CO. V. ROPES & GRAY, 65 F.3D 973, 984-85 (1ST CIR. 1995) (RECOGNIZING
 BANKRUPTCY COURT'S ABILITY TO ISSUE THIRD PARTY INJUNCTIONS). ALTHOUGH MUNFORD
 WAS DECIDED IN THE CONTEXT OF AN ADVERSARY PROCEEDING, THE ELEVENTH CIRCUIT'S
REASONING IN MUNFORD IS DIRECTLY APPLICABLE TO THESE CHAPTER 11 CASES AND, GIVEN
   THE HISTORY OF THE DEBTORS AND THE FCC, COULD NOT BE ANY MORE COMPELLING.

   ARTICLE LVI. AS THE COURT IS KEENLY AWARE, THIS BANKRUPTCY HAS A LONG AND
COMPLICATED HISTORY. LITIGATION BETWEEN THE DEBTORS AND THE FCC EVENTUALLY FOUND
 ITS WAY TO THE SUPREME COURT AFTER WINDING THROUGH NUMEROUS COURTS AND THE FCC
     REGULATORY PROCESS. THE LICENSES IN WHICH THE FCC CLAIMS LIENS ARE THE
CENTERPIECE OF THE DEBTORS' ESTATES AND NOT ONLY HAVE BEEN, BUT REMAIN, SUBJECT
TO ON-GOING DISPUTE AND POTENTIALLY ADDITIONAL LITIGATION. BY ISSUING THE THIRD
   PARTY RELEASES, DISPUTES AND DISAGREEMENTS WITH RESPECT TO THE DESIGNATED
 LICENSES WILL BE FOREVER LAID TO REST, AND THE ESTATES WILL RECEIVE A MINIMUM
   (DEPENDING ON OVERBIDS) OF $666 MILLION WITH WHICH TO SATISFY THE DEBTORS'
OBLIGATIONS UNDER THE DIP LOAN (ESTIMATED TO BE APPROXIMATELY $230 MILLION) WITH
                               THE BALANCE - MORE

 THAN $400 MILLION - TO BE USED BY THE DEBTORS TO FOSTER THEIR REORGANIZATION.
  THUS, THERE IS SIGNIFICANT AND VALUABLE CONSIDERATION BEING PROVIDED FOR THE
  RELEASE OF THE FCC PROVIDED FOR IN THE AGREEMENT, WHICH IS ITSELF LIMITED TO
   JUST THE DESIGNATED LICENSES - ALL CLAIMS IN RESPECT OF THE NON-DESIGNATED
 LICENSES AND ANY OR ALL NON-LICENSE SPECIFIC CLAIMS WILL REMAIN INTACT AND NOT
RELEASED, SUBJECT TO A PRO-RATA DAMAGE REDUCTION FOR THE PROPORTIONATE VALUE OF
THE DESIGNATED LICENSES. ALTHOUGH THERE IS NOT AN ADVERSARY PROCEEDING CURRENTLY
  PENDING WITH RESPECT TO THE DESIGNATED LICENSES, THE FCC'S REVOCATION OF THE
  DEBTORS' LICENSES IN JANUARY 2000 HAS RAISED QUESTIONS REGARDING HOW, AND TO
  WHAT EXTENT, THE DEBTORS HAVE BEEN DAMAGED BY THE FCC'S ACTIONS. THE DEBTORS
 HAVE ALSO EVALUATED CLAIMS ARISING FROM THE FCC'S ACTIONS WITH RESPECT TO THE
DEBTORS' PRIOR PLANS AND BANKRUPTCY PROCEEDINGS IN GENERAL. THESE QUESTIONS, AND
ANY CLAIMS THAT MAY ARISE FROM THEM, ARE NOT RELEASED IN THEIR ENTIRETY AND MAY
 BE SUBJECT TO DISPUTE, AT LEAST TO THE EXTENT THAT THEY IMPACT THE DESIGNATED
 LICENSES, THEY WILL BE RESOLVED BY THE LIMITED RELEASES, EFFECTING A REDUCTION
IN THE POTENTIAL SCOPE OF THE DISPUTES BETWEEN THE DEBTORS AND THE FCC. THE FCC
 BELIEVES THAT THERE ARE VALID DEFENSES TO ANY AND ALL CLAIMS THE DEBTORS MIGHT
                             BRING AGAINST THE FCC.

  ARTICLE LVII. IN ADDITION, BY APPROVING THE TRANSACTION SET FORTH HEREIN AND
     APPROVING THE RELEASES, THE COURT WILL UNQUESTIONABLY FOSTER THE PLAN
FORMULATION AND REORGANIZATION PROCESS. IN SECURITIES AND EXCHANGE COMMISSION V.
THE DREXEL BURNHAM LAMBERT GROUP, INC. (IN RE THE DREXEL BURNHAM LAMBERT GROUP,
    INC.), 960 F.2D 285 (2D CIR. 1992), THE SECOND CIRCUIT STATED THAT "[I]N
   BANKRUPTCY CASES, A COURT MAY ENJOIN A CREDITOR FROM SUING A THIRD PARTY,
 PROVIDED THE INJUNCTION PLAYS AN IMPORTANT PART IN THE DEBTOR'S REORGANIZATION
   PLAN") (CITING IN RE A.H. ROBINS CO., 880 F.2D 694, 701 (4TH CIR.), CERT.
  DENIED, 493 U.S. 959 (1989)). MANY OTHER COURTS, BOTH WITHIN AND WITHOUT THE
    SECOND CIRCUIT, HAVE APPROVED OF THIRD PARTY RELEASES WHEN THEY PLAY AN
    IMPORTANT ROLE IN THE REORGANIZATION PROCESS, OR WHERE THE FAILURE OF AN
    INJUNCTION/RELEASE TO ISSUE WILL ADVERSELY IMPACT THE ESTATE OR CREDITOR
RECOVERIES. SEE, E.G., IN RE CONTINENTAL AIRLINES, 203 F.3D 203 (3D CIR. 2000);

  ARTICLE LVIII. ABSENT APPROVAL OF THE REQUESTED RELEASES IN THIS CASE, THERE
 WILL UNQUESTIONABLY BE HARM TO THE ESTATES, IN THAT THE AGREEMENT AND THE FCC
TERM SHEET, WHICH IS SPECIFICALLY CONDITIONED UPON THE FCC RECEIVING THE LIMITED
 RELEASES, RESULT IN THE DEBTORS' RECEIPT OF AT LEAST $666 MILLION OF EARMARKED
PROCEEDS. ONCE THE LIENS SECURING THE INDEBTEDNESS UNDER THE DIP LOAN (ESTIMATED
AT APPROXIMATELY $230 MILLION) ARE SATISFIED, THIS MONEY WILL BE UNENCUMBERED BY
  ANY FCC CLAIMS OR LIENS AND MAY BE USED BY THE DEBTORS TO FUND, AMONG OTHER
 THINGS, OPERATING EXPENSES, ON-GOING ADMINISTRATIVE EXPENSES AND, UNDER A PLAN
 OF REORGANIZATION, DISTRIBUTION TO THE DEBTORS' CREDITORS. ABSENT APPROVAL OF
THIS MOTION AND THE ACCOMPANYING RELEASES FOR THE FCC, THE ESTATES WILL LOSE THE
  OPPORTUNITY TO RECEIVE THE BENEFIT OF THESE FUNDS, WITH OBVIOUS AND ADVERSE
 EFFECTS ON THE DEBTORS' ESTATES AND THEIR REORGANIZATION EFFORTS. IN ADDITION,
 THE DEBTORS RE-EMPHASIZE THAT THE RELEASES ARE LIMITED ONLY TO THE DESIGNATED
  LICENSES - ALL OTHER CLAIMS AND CAUSES OF ACTION ARE PRESERVED. THE SALE IS,
 HOWEVER, CONTINGENT UPON APPROVAL OF THE FCC TERM SHEET, WITHOUT MODIFICATION,
  AND IT IS THEREFORE CRITICAL TO THE ESTATES THAT SUCH APPROVAL BE OBTAINED.

ARTICLE LIX. FINALLY, NOTWITHSTANDING THE FACT THAT THE FIFTH CIRCUIT'S OPINION
  IN FELD V. ZALE CORP. (IN RE ZALE CORP.), 62 F.3D 746 (5TH CIR. 1995) WOULD
APPEAR TO HOLD TO THE CONTRARY, THE DEBTORS RESPECTFULLY SUBMIT THAT, EVEN UNDER
ZALE, THE PROPOSED RELEASES ARE APPROPRIATE, AS ZALE CAN BE LIMITED TO ITS FACTS
                 AND OTHERWISE DISTINGUISHED FROM THESE CASES.

 ARTICLE LXI. THE MOST IMPORTANT AND CRITICAL DISTINGUISHING FEATURE OF ZALE IS
THAT ZALE INVOLVED DIRECTOR AND OFFICER LITIGATION AND THE INJUNCTION WOULD HAVE
  ULTIMATELY DEPRIVED AT LEAST TWO PARTIES FROM RECOVERING ON AFFIRMATIVE AND
   DIRECT CONTRACT RIGHTS. NO SUCH SITUATION EXISTS HERE, AS, TO THE DEBTORS'
KNOWLEDGE, IT IS ONLY THEY WHO HAVE DIRECT PRIVITY WITH THE FCC WITH RESPECT TO
                            THE DESIGNATED LICENSES.

ARTICLE LXII. AS A RESULT, AND BASED UPON THE FACTS AND HISTORY OF THESE CHAPTER
 11 CASES AND THE DEBTORS' RELATIONSHIP WITH THE FCC, THE DEBTORS RESPECTFULLY
  SUBMIT THAT THE COURT IS AUTHORIZED TO ISSUE THE REQUESTED RELEASES AND, IN
                  FACT, THAT IT WOULD BE APPROPRIATE TO DO SO.

two-step process. First, the Debtors are requesting a hearing on August 21, 2003
(the "Bidding Procedures Hearing") on the preliminary matters which are
necessary for the bidding process and ultimately the Sale Hearing to proceed.
Specifically, at the Bidding Procedures Hearing, the Debtors intend to seek
approval of the matters set forth in Sections F (Bidding Procedures), G
(Break-Up Fee and Expense Reimbursement) and J (Notice) hereof (collectively
referred to as the "Initial Approvals") and will request that the Bidding
Procedures Order specifically provide that approval of the FCC Term Sheet
without modification in the Sale Order is a condition precedent to the Sale
proceeding. Should the Bidding Procedures Order be entered following the Bidding
Procedures Hearing, the Debtors will provide subsequent notice as set forth in
Section J below and in accordance with the Notice of Auction and Sale Hearing
attached hereto as Exhibit "D," of the Sale Hearing and deadlines attendant
thereto. Approval of the Sale and the FCC Term Sheet, as a condition precedent

                                 SCHEDULE 3.4(C)
                ARTICLE LXVI. JUDICIAL OR ADMINISTRATIVE CLAIMS

1.       NextWave's Qualifications to Hold Licenses. In the NextWave Licensing
         Order, the Bureau granted the 63 NextWave C Block licenses there at
         issue. In doing so, the Bureau stated the grants were made despite lack
         of full compliance with all applicable foreign ownership rules.
         Nevertheless, it granted the licenses in order to serve the public
         interest, conditioned on NextWave restructuring to conform to all
         applicable foreign ownership rules. On April 10, 1998, NextWave filed a
         demonstration of compliance and a petition seeking a declaration ruling
         that, in light of the FCC's implementation of the World Trade
         Organization's Basic Telecommunications Agreement, NextWave's
         pre-existing ownership structure complied with all applicable foreign
         ownership rules. On May 13, 2003, at the FCC's request, NextWave
         Telecom, Inc. filed with the FCC supplemental ownership information. On
         July 14, 2003, the FCC's Wireless Telecommunications Bureau and
         International Bureau issued an Order granting NextWave's petition for
         declaratory ruling and found that NextWave "has complied fully with the
         conditions to restructure its indirect foreign ownership within the 25%
         percent benchmark of Section 310(b)(4) or demonstrate that it is in the
         public interest to permit it to exceed the benchmark. We therefore
         remove this and related conditions imposed upon the grant of the
         C-Block licenses to NextWave." This Order will become a Final Order on
         August 13, 2003, absent some intervening action by the Commission or a
         third party.

2.       N.Y. Telecom, LLC's Application for Review. On April 2, 2003, N.Y.
         Telecom, LLC ("N.Y. Telecom") filed an Application for Review of the
         Bureau's Order, DA 03-617 (rel. March 3, 2003), in which the Bureau
         ruled that NextWave's five-year construction period had been tolled for
         a period of 703 days, thereby extending the application construction
         deadlines by that period. (N.Y. Telecom had previously challenged the
         sufficiency of NextWave's construction showings, and argues in this
         Application for Review that the Bureau erred in finding that the
         construction period was tolled.) NextWave filed an opposition to the
         Application for Review on April 17, 2003, explaining that the N.Y.
         Telecom Application for Review is meritless. N.Y. Telecom filed a reply
         to that opposition on April 28, 2003. This matter remains pending with
         the FCC.

3.       Pursuant to FCC rules, Section 24.237, et seq, Sellers may owe monies
         to other Broadband PCS carriers as a result of those carriers
         relocating or otherwise acting to clear incumbent 2 GHz microwave
         carriers. To date, Sellers have received invoices from other carriers
         totaling $6,906,160, and have been advised by the PCIA clearinghouse
         charged with overseeing the microwave clearance program that total
         invoices (including those referenced above) could amount to
         $10,304,082. Sellers do not believe that any such arguable obligations
         constitute an encumbrance or lien on the Licenses, but are agreeing
         that any alleged encumbrance as a result of these obligations will
         attach to the proceeds of the Sale and, when allowed by the Bankruptcy
         Court, be paid in full in cash by the Sellers as administrative claims
         of their bankruptcy estates.

                                  ENCUMBRANCES

Sellers incurred obligations to the FCC in connection with the acquisition of
        the Licenses through competitive bidding processes conducted by the
        FCC. The transaction contemplated in this Agreement gives rise to
        payment obligations by Sellers' under Section 1.2111 of the FCC's
        rules. Due to circumstances arising out of the FCC's cancellation of
        the Licenses, the precise amount of these obligations due to the FCC
        has not yet been determined. Both the FCC and BFD Communications
        Partners, L.P. (the latter as administrative agent and lender under
        Sellers' debtor-in-possession financing) claim to hold liens on the
        Licenses. These Encumbrances will be fully released upon Closing of the
        transaction contemplated in this Agreement.

Pursuant to FCC rules, Section 24.237, et seq, Sellers may owe monies to other
        Broadband PCS carriers as a result of those carriers relocating or
        otherwise acting to clear incumbent 2 GHz microwave carriers. To date,
        Sellers have received invoices from other carriers totaling $6,906,160,
        and have been advised by the PCIA clearinghouse charged with overseeing
        the microwave clearance program that total invoices (including those
        referenced above) could amount to $10,304,082. Sellers do not believe
        that any such arguable obligations constitute an encumbrance or lien on
        the Licenses, but are agreeing that any alleged encumbrance as a result
        of these obligations will attach to the proceeds of the Sale and, when
        allowed by the Bankruptcy Court, be paid in full in cash by the Sellers
        as administrative claims of their bankruptcy estates.
