<PAGE>

                  and to carry on its business as now being conducted and
                  proposed to be conducted.

            (2)   It has the requisite power and authority to execute, deliver
                  and perform this Agreement and each other instrument,
                  document, certificate and agreement required or contemplated
                  to be executed, delivered and performed by it hereunder and
                  thereunder to which it is or will be a party.

            (3)   It is duly qualified to do business in each jurisdiction where
                  the character of its properties owned or held under lease or
                  the nature of its activities makes such qualification
                  necessary other than any such jurisdiction in which the
                  failure to be so qualified would not have a Material Adverse
                  Effect on it or materially adversely affect the Transaction or
                  its ability to perform its obligations under this Agreement.

            (4)   The execution and delivery of this Agreement by it and the
                  consummation of the Transaction by it have been duly and
                  validly authorized by its Board of Directors (or equivalent
                  body) and no other proceedings on its part which have not been
                  taken (including, without limitation, approval of its members,
                  managers or other constituent bodies, as the case may be) are
                  necessary to authorize this Agreement or to consummate the
                  Transaction.

            (5)   This Agreement has been duly executed and delivered by it and
                  constitutes the valid and binding obligation of it,
                  enforceable against it in accordance with its terms, except as
                  such enforceability may be limited by bankruptcy, insolvency,
                  moratorium or other similar laws affecting or relating to
                  enforcement of creditors' rights generally and may be subject
                  to general principles of equity.

            (6)   As of the Closing, after giving effect to the Transaction, it
                  is not in breach of any obligation under this Agreement.

      4.2 Consents; No Conflicts. Neither the execution, delivery and
performance by it of this Agreement nor the consummation of the Transaction will
(a) conflict with, or result in a breach or violation of, any provision of its
organizational documents; (b) constitute, with or without the giving of notice
or passage of time or both, a breach, violation or default, create a Lien, or
give rise to any right of termination, modification, cancellation, prepayment or
acceleration, under (i) any Law or License or (ii) any note, bond, mortgage,
indenture, lease, agreement or other instrument, in each case which is
applicable to or binding upon it or any of its assets; or (c) other than the
consents of the FCC and its lenders, require any Consent or the approval of its
members, officers, Board of Directors or similar constituent bodies, as the case
may be (which approvals have not been obtained). There is no fact relating to it
or its Affiliates that would be reasonably expected to prevent it from
consummating the Transaction or disqualify the Company from


                                      -5-
<PAGE>

obtaining the Consents (including without limitation, FCC Consent) required in
order to consummate the License Transfer as provided for in this Agreement.

      4.3 Litigation. There is no action, proceeding or investigation pending
or, to its knowledge threatened against it or any of its properties or assets
that would be reasonably expected to have an adverse effect on its ability to
consummate the Transaction or to fulfill its obligations under this Agreement,
or which seeks to prevent or challenge the Transaction.

      4.4 Brokers. It has not employed any broker, finder or investment banker
or incurred any liability for any brokerage fees, commissions or finder's fees
in connection with the Transaction.

      4.5 ABC Licenses. It is the authorized legal holder of each ABC License, a
true and correct copy of which is attached hereto as Schedule I, which, as of
Closing, will be free and clear of any Liens. Each ABC License is valid and in
full force and effect. There is not pending nor to its knowledge threatened
against ABC or against any ABC License, any application, action, petition,
objection or other pleading, or any proceeding with the FCC which questions or
contests the validity of, or seeks the revocation, nonrenewal or suspension of,
any ABC License, which seeks the imposition of any modification or amendment
with respect thereto, or which would have a Material Adverse Effect on the
ability of the Company to employ any ABC License in its business. None of the
ABC Licenses is subject to any conditions other than those appearing on the face
of such ABC License itself and those imposed by FCC Law. It complies in all
material respects with all aspects of FCC Law, including: (i) the rules,
regulations and policies pertaining to eligibility to hold Broadband PCS
licenses in general, and the ABC Licenses, in particular, including without
limitation Section 24.709 of the FCC's rules; and (ii) the rules, regulations
and policies governing the CMRS spectrum cap and restricting foreign ownership
of radio licenses.

                  to be executed,

                  delivered and performed by it hereunder and thereunder to
                  which it is or will be a party.

            (3)   It is duly qualified to do business in each jurisdiction where
                  the character of its properties owned or held under lease or
                  the nature of its activities makes such qualification
                  necessary other than any such jurisdiction in which the
                  failure to be so qualified would not have a Material Adverse
                  Effect on it or materially adversely affect the Transaction or

            (4)   The execution and delivery of this Agreement by it and the
                  consummation of the Transaction by it have been duly and
                  validly authorized by its Board of Directors (or equivalent

                  moratorium or other similar laws affecting or relating to
                  enforcement of creditors' rights generally and may be subject
                  to general principles of equity.

            (6)   As of the Closing, after giving effect to the Transaction, it
                  is not in breach of any obligation under this Agreement.

its obligations under this Agreement. To its knowledge, there is no fact
relating to it or its Affiliates that would be reasonably expected to prevent it

reasonable efforts to take, or cause to be taken, all actions, and to do, or

            (1)   The parties shall use all commercially reasonable efforts to
                  cause the Closing to occur and the Transaction to be
                  consummated in accordance with the terms hereof, and, without
                  limiting the generality of the foregoing, to obtain all
                  necessary Consents including, without limitation, the approval
                  of this Agreement and the Transaction by all Governmental
                  Authorities and agencies, including the FCC, and make all
                  filings with and to give all notices to third parties which
                  may be necessary or reasonably required in order for the
                  parties to consummate the Transaction. ABC and the Company (or

            (2)   Each party shall furnish to the other party all information
                  concerning such party and its Affiliates reasonably required

            (3)   Upon the request of any other party, each party shall
                  forthwith execute and deliver, or cause to be executed and
                  delivered, such further instruments of assignment, transfer,
                  conveyance, endorsement, direction or authorization and other

                  order to effectuate the purposes of this Agreement.

            Nothing in this Agreement shall be construed to require the parties
to consummate the Closing if any regulatory approval would require that it (i)
divest or hold separate any of its assets existing as of the date hereof other
than as contemplated by this Agreement or (ii) otherwise take or commit to take
any action that limits its freedom of action in any material respect with
respect to any of its businesses, product lines or assets.

      6.2 Confidentiality.

            (1)   Each party shall, and shall cause each of its Affiliates, and
                  its and their respective shareholders, members, managers,
                  directors, officers, employees and agents (collectively,
                  "Representatives") to, keep secret and retain in strictest
                  confidence any and all Confidential Information relating to
                  any other party that it receives in connection with the
                  negotiation or performance of this Agreement, and shall not
                  disclose such Confidential Information, and shall cause its
                  Representatives not to disclose such Confidential Information,
                  to anyone except the receiving party's Affiliates and
                  Representatives and any other Person that agrees in writing to
                  keep in confidence all Confidential Information in accordance
                  with the terms of this Section 6.2. Until the Closing, each
                  party agrees to use Confidential Information received from
                  another party only (i) to evaluate its interest in pursuing
                  the Transaction and (ii) to pursue such Transaction, but not
                  for any other purpose. All Confidential Information furnished
                  pursuant to this Agreement shall be returned promptly to the
                  party to whom it belongs upon request by such party.

            (2)   The obligations set forth in Section 6.2(1) shall be
                  inoperative with respect to Confidential Information that (i)
                  is or becomes generally available to the public other than as
                  a result of disclosure by the receiving party or its
                  Representatives, (ii) was available to the receiving party on
                  a non-confidential basis prior to its disclosure to the
                  receiving party, or (iii) becomes available to the receiving
                  party on a non-confidential basis from a source other than the
                  providing party or its agents, provided that such source is
                  not known by the receiving party to be bound by a
                  confidentiality agreement with the providing party or the
                  Representatives.

            (3)   To the fullest extent permitted by law, if a party or any of
                  its Affiliates or Representatives breaches, or threatens to
                  commit a


                                      -9-
<PAGE>

                  breach of, this Section 6.2, the party whose Confidential
                  Information shall be disclosed, or threatened to be disclosed,
                  shall have the right and remedy to have this Section 6.2
                  specifically enforced by any court having jurisdiction, it
                  being acknowledged and agreed that money damages will not
                  provide an adequate remedy to such party. Nothing in this
                  Section 6.2 shall be construed to limit the right of any party
                  to collect money damages in the event of breach of this
                  Section 6.2.

            (4)   Anything else in this Agreement notwithstanding, each party
                  shall have the right to disclose any information, including
                  Confidential Information of the other party or such other
                  party's Affiliates, in any filing with any regulatory agency,
                  court or other authority or any disclosure to a trustee of
                  public debt of a party to the extent that the disclosing party
                  determines in good faith that it is required by Law,
                  regulation or the terms of such debt to do so, provided that
                  any such disclosure shall be as limited in scope as possible
                  and shall be made only after giving the other party as much
                  notice as practicable of such required disclosure and an
                  opportunity to contest such disclosure if possible.

      6.3 Certain Covenants. From and after the execution and delivery of this
Agreement to and including the Closing Date, ABC shall:

                  liability, absolute or contingent, relating to or affecting
                  any ABC License or its use.

                  commencement of, or upon obtaining knowledge of any facts that
                  would give rise to a threat of, any claim, action or
                  proceeding commenced against or relating to (i) it, its
                  properties or assets, including any ABC License or its use,
                  and which could have a Material Adverse Effect on it or

                  the impending or threatened occurrence of, any event which
                  could cause or constitute a material breach of any of its
                  warranties, representations, covenants or agreements contained
                  in this Agreement, give notice in writing of such event, or

                  remedy such breach; and

            (6)   cause the Company to be advised promptly in writing of (i) any

                  or (ii) any claim, action or proceeding which seeks to enjoin
                  the consummation of the Transaction.

                  approve any counsel selected by the Indemnifying Party and to
                  approve the terms of any proposed settlement, such approval
                  not to be unreasonably delayed or withheld (unless such
                  settlement provides only, as to the Indemnified Party, the
                  payment of money damages actually paid by the Indemnifying
                  Party and a complete release of the Indemnified Party in
                  respect of the claim in question). Notwithstanding any of the
                  foregoing to the contrary, the provisions of this Article VIII
                  shall not be construed so as to provide for the
                  indemnification of any Indemnified Party for any liability to
                  the extent (but only to the extent) that such indemnification
                  would be in violation of applicable law or that such liability
                  may not be waived, modified or limited under applicable law,
                  but shall be construed so as to effectuate the provisions of
                  this Article VIII to the fullest extent permitted by law.

            (2)   In the event that the Indemnifying Party undertakes the
                  defense of any Claim, the Indemnifying Party will keep the
                  Indemnified Party advised as to all material developments in
                  connection with such Claim, including, but not limited to,
                  promptly furnishing the Indemnified Party with copies of all
                  material documents filed or served in connection therewith.

            (3)   In the event that the Indemnifying Party fails to assume the
                  defense of any Claim within ten business days after receiving
                  written notice thereof, the Indemnified Party shall have the
                  right, subject to the Indemnifying Party's right to assume the
                  defense pursuant to the provisions of this Article VIII, to
                  undertake the defense, compromise or settlement of such Claim
                  for the account of the Indemnifying Party. Unless and until
                  the Indemnified Party assumes the defense of any Claim, the
                  Indemnifying Party shall advance to the Indemnified Party any
                  of its reasonable attorneys' fees and other costs and expenses
                  incurred in connection with the defense of any such action or
                  proceeding. Each Indemnified Party shall agree in writing
                  prior to any such advancement that, in the event he or it
                  receives any such advance, such Indemnified Party shall
                  reimburse the Indemnifying Party for such fees, costs and
                  expenses to the extent that it shall be determined that he or
                  it was not entitled to indemnification under this Article
                  VIII.

            (4)   In no event shall an Indemnifying Party be required to pay in
                  connection with any Claim for more than one firm of counsel
                  (and local counsel) for each of the following groups of
                  Indemnified Parties: (i) ABC, its Affiliates, and the
                  shareholders, members, managers, directors, officers,
                  employees, agents and/or the legal representatives of any of
                  them; and (ii) the Company and its Affiliates, and the
                  shareholders, members, managers, directors,


                                      -15-

                  officers, employees, agents and/or the legal representatives
                  of any of them.

                  is not otherwise in breach of its obligations under this
                  Agreement;

            (3)   by any party by written notice to the other party, if the
                  consummation of the Transaction shall be prohibited by a
                  final, non-appealable order, decree or injunction of a court
                  of competent jurisdiction.

      9.2 Effect of Termination. In the event of a termination of this
Agreement, no party hereto shall have any liability or further obligation to any
other party to this Agreement, except as set forth in paragraph (2) below, and
except that nothing herein will relieve any party from liability for any breach
by such party of this Agreement.

            (1)   In the event of a termination of this Agreement pursuant to
                  Section 9.1, all provisions of this Agreement shall terminate,
                  except Section 6.2 and Articles VIII and X..

            (2)   Whether or not the Closing occurs, all costs and expenses
                  incurred in connection with this Agreement and the Transaction
                  shall be paid by the party incurring such expenses.

                                   ARTICLE X

failure to insist upon strict compliance with such obligation, covenant,
agreement or condition shall not operate as a waiver of, or

estoppel with respect to, any subsequent or other failure. Whenever this
