PCS Authorizations held directly or indirectly by WWC, and all interests of the
WWC Non-Company Group (as defined in the Shareholders Agreement) in any PCS
Authorization (including the limited partnership interest of the WWC Non-Company
Group in Cook), whether or not listed on EXHIBIT 4.01(i) annexed hereto, and
(ii) all rights of the WWC Non-Company Group to acquire any PCS Authorization or
any interest in any PCS Authorization, including pursuant to the Agreements
dated April 24, 1997 among WWC and Triad Cellular Corporation, Triad Cellular
L.P. and/or certain of their Affiliates. Accordingly, at the Closing the Company
and its Subsidiaries will own all of the PCS Authorizations, and all interests
of WWC or its Subsidiaries in any PCS Authorization, owned by the WWC Group (as
defined in the Shareholders Agreement) immediately prior to the Closing.

            (l) Capitalization of the Company at the Closing. Prior to or
simultaneously with the Closing, WWC shall take, or cause to be taken, all
actions necessary or required for (i) all liabilities or obligations of the
Company Group to the WWC Non-Company Group to be converted into Common Stock (or
additional paid-in capital in respect of Common Stock), so that immediately
after the Closing, no member of the Company Group shall have any liabilities or
obligations to any member of the WWC Non-Company Group, other than pursuant to
the Intercompany Agreements, and (ii) all liabilities or obligations of the WWC
Non-Company Group to the Company Group to be satisfied, so that immediately
after the Closing no member of the WWC Non-Company Group shall have any
liabilities or obligations to any member of the Company Group. If, at the
Closing, the total equity contributed by WWC, its shareholders and its
Subsidiaries (other than the Company or its Subsidiaries) to the Company and its
Subsidiaries in cash (including (i) any payments of interest or other amounts
paid by WWC on behalf of, or in connection with loans, the proceeds of which
were used for the benefit of the Company or its Subsidiaries, and (ii) the
amount of liabilities and obligations converted to Common Stock (or additional
paid-in capital in respect of Common Stock) as provided in this SECTION 3.01(l))
is less than Seven Hundred Fifty Million ($750,000,000) Dollars then, on the
Closing Date, WWC shall contribute in cash to the Company an amount equal to
such shortfall. If, at the Closing, the total equity so contributed by WWC, its
shareholders and its Subsidiaries (other than the Company or its Subsidiaries)
to the Company and its Subsidiaries (including the amount of liabilities and
obligations converted to Common Stock (or additional paid-in capital in respect
of Common Stock) as provided in this SECTION 3.01(1)) is greater than Seven
Hundred Fifty Million ($750,000,000) Dollars then, on the Closing Date, the
Company shall pay to WWC in cash an amount equal to such excess. The
contributions and repayments, if any, pursuant to this SECTION 3.01(l) shall not
have any dilutive effect on (A) the 19.9% interest in the Company's outstanding
Common Stock to be held by the Investor as a result of the Closing or (B) the
80.1% interest in the Company's outstanding Common Stock to be held by WWC as a
result of the Closing.

has full power and authority to execute, deliver and perform its obligations
under this Agreement and the Intercompany Agreements and the Shareholders
Agreement and to consummate the transactions contemplated hereby or thereby,

incorporation and by-laws to be in the form of Exhibit 3.01(f) annexed hereto

parties thereto each of the Intercompany Agreements and the Shareholders
Agreement shall constitute, a legal, valid and binding obligation of WWC and the
Company enforceable 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. Except as
described on EXHIBIT 4.01(b) annexed hereto, neither the execution, delivery or
performance of this Agreement or, upon their execution, the Intercompany
Agreements or the Shareholders Agreement, nor the consummation of the
transactions contemplated hereby or thereby by WWC and the Company will, with or
without the giving of notice or the passage of time, or both, (i) conflict with,
result in a default or loss of rights (or give rise to any right of termination,
cancellation or acceleration) under, or result in the creation of any Lien,
pursuant to (A) any provision of the certificates of incorporation, by-laws,
stockholders agreements or other constituent documents of WWC or the Company (it

WWC and the Company threatened, against or relating to the right of WWC or the
Company to perform its obligations under this Agreement, any Intercompany
Agreement or the Shareholders Agreement, nor do WWC and the Company know or have
reason to be aware of any basis for the same. There is outstanding no order,
writ, injunction, judgment or decree of any court, governmental agency or
arbitration tribunal which would individually or in the aggregate impair in any
material respect the performance of the obligations of WWC and the Company
hereunder or under the Intercompany Agreements or the Shareholders Agreement or
the consummation of the transactions contemplated hereby or thereby other than
orders or decrees involving the wireless telephone industry in general.

            (d) Truth and Correctness. No representation or warranty by WWC or
the Company in this Agreement, any Intercompany Agreement or the Shareholders
Agreement contains or will contain any untrue statement of a material fact or
omits or will omit to state a material fact necessary to make the statements
contained herein or therein, in light of the circumstances under which such
statements are made, not misleading.

            (e) Purchased Shares. The Purchased Shares shall, at the Closing, be
duly authorized by all necessary corporate action on the part of the Company,
shall be (when issued in accordance with the terms of this Agreement) validly
issued and outstanding, fully paid and nonassessable, and shall not be subject
to any preemptive rights of the holders of any other class or series of the
capital stock of the Company. Upon the issuance of the Purchased Shares to the
Investor at the Closing, the Purchased Shares shall be free and clear of all
Liens of any nature whatsoever, with the exception of any restrictions on

                                       12
<PAGE>   15
Agreement or under the Securities Act or any securities laws of any
jurisdiction.

            (f) No Brokers. Except for Goldman, Sachs & Co., no agent, broker,

finder's fee or any other commission or similar fee directly or indirectly in
connection with the transactions contemplated by this Agreement based in any way
on any arrangements, agreements or understandings made by or on behalf of WWC or
the Company or an Affiliate of either thereof, and WWC and the Company hereby
jointly and severally agree to indemnify the Investor and agree to hold harmless
the Investor against and in respect of any claims (including those of Goldman,
Sachs & Co.) for brokerage and other commissions relating to such transactions
based in any way on any arrangements, agreements or understandings made by or on
behalf of WWC or the Company or an Affiliate of either thereof.

            (g) Financial Statements. EXHIBIT 4.01(g) annexed hereto contains a
list of financial statements of the Company and its Subsidiaries for the periods
indicated on such EXHIBIT 4.01(g) (the "Operating Financial Statements"). True
and complete copies of each item listed thereon have previously been delivered
to the Investor. The Operating Financial Statements are, and the Quarterly
Operating Statements will be, prepared on a consistent basis in accordance with
generally accepted accounting principles and true and correct in all material
respects.

            (h) Compliance with Laws. Except as set forth on EXHIBIT 4.01(c)
annexed hereto, each of WWC, the Company, each of their respective Subsidiaries
and Cook is in compliance with all applicable laws, regulations, administrative
orders and Authorizations of the United States and the states in which the
Company or its Subsidiaries or Cook transact business (including all applicable
rules, regulations and Authorizations of the FCC, any state public utilities or
public service commission, or any other Federal or state governmental agency or
instrumentality exercising jurisdiction over the Company), and of each
municipality, county or subdivision of any thereof, to which any of its
businesses or any of its properties may be subject, the non-compliance with
which would have a Material Adverse Effect upon the Company.

            (i) Authorizations.

                (i) Each of the Company, each of its Subsidiaries and Cook has
(A) all requisite Authorizations of the FCC (including all PCS Authorizations)
and of all state public utility or public service commissions and (B) all other
material Authorizations of governmental agencies exercising jurisdiction over
the Company or any Subsidiary or Cook required to carry on its or their business
as now conducted or as contemplated to be conducted, except for any
Authorizations, the failure of which to obtain would not have a Material Adverse
Effect on the Company or a material adverse effect on any PCS Authorization. All
PCS Authorizations (including those not now owned by the Company or its
Subsidiaries but which are to be transferred to the Company or its Subsidiaries
prior to the Closing Date in accordance with SECTION 3.01(k) hereof) which are
contemplated by this Agreement to be held, directly or 




                                       13
<PAGE>   16
indirectly, by the Company are listed on EXHIBIT 4.01(i) annexed hereto.

                (ii) The Company's Authorizations are in full force and effect
and have not been suspended, modified in any material adverse respect, canceled
or revoked, and each of WWC, the Company, each of their respective Subsidiaries
and Cook has operated in compliance with all terms thereof or any renewals
thereof applicable to it except where failure to so comply would not have a
Material Adverse Effect on the Company or a material adverse effect on any PCS
Authorization. No event has occurred with respect to any of the Authorizations
which permits, or after notice or lapse of time or both would permit, revocation
or termination thereof or would result in any other material impairment of the
rights of the holder of any such Authorizations, except to the extent such
revocation, termination or impairment would not have a Material Adverse Effect
on the Company or a material adverse effect on any PCS Authorization. Except as
set forth on EXHIBIT 4.01(i) annexed hereto, there is not pending as of the date
hereof any application, petition, objection or other pleading with the FCC or
any public service commission or similar body having jurisdiction or authority
over the communications operations of the Company and its Subsidiaries which
questions the validity of, or which presents a substantial risk that, if
accepted or granted, would result in the revocation, cancellation, suspension or
any materially adverse modification of, any such Authorizations, except to the
extent such invalidity, revocation, cancellation, suspension or modification
would not have a Material Adverse Effect on the Company or a material adverse
effect on any PCS Authorization.

            (j) Taxes. WWC, the Company and their respective Subsidiaries have
timely filed all Federal, state, county, local and foreign Tax Returns required
to be filed by them, and have paid all Taxes which have become due pursuant
thereto or otherwise, other than Taxes the liability for which is being
contested in good faith and appropriate reserves for which have been made in the
Company's financial statements. Except as set forth on EXHIBIT 4.01(j) annexed
hereto, there are no additional assessments or adjustments of Taxes pending or
threatened against WWC, the Company or their respective Subsidiaries for any
period.

            (k) No Material Adverse Change. Since June 30, 1997, there has not
been any event or condition which has caused, or is reasonably likely to cause,
a Material Adverse Effect on the Company, other than as a result of conditions
affecting PCS systems generally.

            (l) Employee Benefit Plans. All employee benefit or employee welfare
plans maintained by WWC, the Company or any of their respective Subsidiaries
which are subject to the Employee Retirement Income Security Act of 1974, as
amended ("ERISA"), comply in all material respects with the requirements of
ERISA, and no such plan which is subject to Part 3 of Subtitle B of Title 1 of
ERISA has incurred any "Accumulated Funding Deficiency" within the meaning of
SECTION 302 of ERISA or SECTION 412 of the Code, and neither WWC nor the Company
has incurred any liability on account of such an "Accumulated Funding
Deficiency" with respect to any such employee benefit plan subject to ERISA. No
liability to the Pension Benefit Guaranty Corporation established under ERISA
has been incurred with respect to any such plan subject to ERISA and neither WWC
nor the Company has incurred any liability for 




                                       14
<PAGE>   17
any tax implied by SECTION 4975 of the Code. As of the most recent valuation
date of any such plan, there are no "unfunded benefit liabilities" within the
meaning of SECTION 4001(a)(18) of ERISA. If WWC, the Company or any of their
respective Subsidiaries were to withdraw completely from any such plan that is a
multiemployer plan, within the meaning of SECTION 3(37) of ERISA, there would be
no "withdrawal liability" within the meaning of SECTION 4201 of ERISA.

            (m) Compliance with other Instruments. Neither WWC, the Company nor
any of their respective Subsidiaries nor Cook is in violation of any term of (i)
any agreement or instrument related to indebtedness for borrowed money or any
other material agreement to which it is a party or by which it is bound, or (ii)
any applicable order, judgment or decree of any court, arbitrator or
governmental authority, the consequences of which violation, whether
individually or in the aggregate, would result in a Material Adverse Effect on
the Company.

            (n) Organization of Subsidiaries. Each Subsidiary of the Company is
listed on Exhibit 4.01(n) annexed hereto and is a corporation or other legal
entity duly organized, validly existing and in good standing under the laws of
the jurisdiction of its organization and is duly qualified and has the full
power and authority in each applicable jurisdiction to own its properties and
conduct its business and operations as currently conducted, except to the extent
that any failure to qualify would not have a Material Adverse Effect on the
Company. Cook is a limited partnership duly organized, validly existing and in
good standing under the laws of Delaware and is duly qualified and has the full
power and authority in each applicable jurisdiction to own its properties and
conduct its business and operations as currently conducted, except to the extent
that any failure to qualify would not have a Material Adverse Effect on the
Company.

            (o) Capital Stock. After giving effect to the Closing hereunder,
12,484 shares of Common Stock will be outstanding, of which 10,000 shares shall
have been issued to WWC, and 2,484 shares shall have been issued to the
Investor. All outstanding shares of the capital stock of the Company at the date
hereof are (and will after giving effect to the Closing be) duly authorized,
validly issued, fully paid and nonassessable, and no class of capital stock of
the Company will at the Closing be entitled to preemptive rights, other than as
set forth in the Shareholders Agreement. There are outstanding no options,
warrants or other rights to acquire capital stock from the Company.

            (p) Investment Company Act. Neither WWC nor the Company is, or will
become after giving effect to the Closing, an "investment company" within the
meaning of the Investment Company Act of 1940, as amended.

        4.2 Representations and Warranties of HTL and the Investor. Each of HTL
and the Investor represents and warrants to the Company and WWC, which
representations and warranties shall survive the execution and delivery of this
Agreement and the consummation of the transactions herein contemplated, as

4.02(b) annexed hereto, neither the execution, delivery or performance of this
Agreement or the Shareholders Agreement nor the consummation of the transactions
contemplated hereby or thereby by HTL or the Investor will, with or without the
giving of notice or the passage of time, or both, (i) conflict with, result in a
default or loss of rights (or give rise to any right of termination,

certificates of incorporation, by-laws, stockholders agreements or other

respective property is bound or affected; or (ii) give rise to any right of
first refusal or similar right with respect to any interest, or any properties
or assets, of either HTL or the Investor. Except as described on EXHIBIT 4.02(b)
annexed hereto, no permit, consent, approval, authorization, qualification or
registration of, or declaration to or filing with any governmental or regulatory
authority or agency or third party is required to be obtained or made by either
HTL or the Investor in connection with the execution and delivery of this
Agreement or the Shareholders Agreement or the consummation of the transactions

                                    ARTICLE 6

                               SURVIVAL; INDEMNITY

        6.1 Survival of Representations and Warranties. Notwithstanding any
investigation or review made at any time by or on behalf of any party hereto,
all representations and warranties contained in this Agreement or in the
EXHIBITS annexed hereto or in any of the agreements, certificates or instruments
delivered in connection herewith shall survive until the termination of the
applicable Indemnification Period and shall thereupon expire together with any
right to indemnification (except with respect to any claim for breach of any
such representation or 




                                       22
<PAGE>   25
warranty for which written notice shall have been given prior to the termination
of the Indemnification Period to the party which made such representation or
warranty).

        6.2 Indemnity by WWC.

            (a) (i) During the Indemnification Period (or thereafter solely with
respect to any claim for which indemnification has been made prior to the
expiration of the Indemnification Period), in addition to any other
indemnification provided for under this Agreement or any Additional Agreement,
the Company (and solely to the extent the Company is unable to do so, WWC) shall
indemnify and hold harmless HTL, the Investor and their respective officers,
directors, employees, stockholders, agents and representatives from and against
any and all demands, claims, losses, liabilities, actions or causes of action,
assessments, actual damages (but excluding consequential damages), fines, Taxes
(including excise and penalty taxes), penalties, costs and expenses, including
interest, expenses of investigation, reasonable fees and disbursements of
counsel, accountants and other experts (collectively "Losses") incurred or
suffered by any such indemnified Person arising out of, resulting from, or
relating to any breach of any of the representations or warranties made by WWC
or the Company in this Agreement or in any agreement, certificate, EXHIBIT or
other instrument delivered by WWC or the Company pursuant to this Agreement.

                (ii) In addition to any other indemnification provided for under
this Agreement or any Additional Agreement, the Company (and solely to the
extent the Company is unable to do so, WWC) shall indemnify and hold harmless
HTL, the Investor and their respective officers, directors, employees,
stockholders, agents and representatives from and against any and all Losses
incurred or suffered by any such indemnified Person arising out of, resulting
from, or relating to any failure by WWC or the Company to perform any of their
covenants or agreements contained in this Agreement or in any agreement,
certificate or other instrument delivered by WWC or the Company pursuant to this
Agreement.

                (iii) HTL and the Investor confirm and agree that if WWC
provides any indemnification under this SECTION 6.02, Losses shall be determined
by considering, among other things, that (A) no portion of the Purchase Price
was paid to WWC, but was paid in full to the Company; (B) the Company has not
made any payment (or has made only a partial payment) to the indemnified person
on account of the indemnification obligation under this SECTION 6.02; and (C)
accordingly, except to the extent that the Company has made any such payment,
there has been no diminution in value of the Company solely as a result of such
indemnification obligation nor has there been any diminution of the Investor's
interest in the Company.

            (b) Notwithstanding anything to the contrary contained in this
SECTION 6.02, neither the Company nor WWC shall be required to pay or reimburse
either HTL or the Investor for Losses pursuant to any of the indemnification
obligations pursuant to this SECTION 6.02; unless the aggregate amount of HTL's
and the Investor's Losses claimed in respect of all such matters, exceeds
$5,000,000, in which event the Investor shall be entitled to seek
indemnification




                                       23
<PAGE>   26
under this SECTION 6.02 for the amount of all such Losses.

        6.3 Indemnity by HTL and the Investor.

            (a) (i) During the Indemnification Period (or thereafter solely with
respect to any claim for which indemnification has been made prior to the
expiration of the Indemnification Period), in addition to any other
indemnification provided for under this Agreement or any Additional Agreement,
each of HTL and the Investor shall, jointly and severally, indemnify and hold
harmless WWC and the Company and their respective officers, directors,
employees, stockholders, agents and representatives from and against any and all
Losses incurred or suffered by any such indemnified person arising out of,
resulting from, or relating to any breach of any of the representations or
warranties made by HTL or the Investor in this Agreement or in any agreement,
certificate, EXHIBIT or other instrument delivered by HTL or the Investor
pursuant to this Agreement.

                (ii) In addition to any other indemnification provided for under
this Agreement or any Additional Agreement, HTL and the Investor shall, jointly
and severally, indemnify and hold harmless WWC and the Company and their
respective officers, directors, employees, stockholders, agents and
representatives from and against any and all Losses incurred or suffered by any
such indemnified Person arising out of, resulting from, or relating to any
failure by HTL or the Investor to perform any of their covenants or agreements
contained in this Agreement or in any agreement, certificate or other instrument
delivered by HTL or the Investor pursuant to this Agreement.

               (b) Notwithstanding anything to the contrary contained in this
SECTION 6.03, HTL and the Investors shall not be required to pay or reimburse
either WWC or the Company for Losses pursuant to any of HTL's or the Investor's
indemnification obligations pursuant to this SECTION 6.03; unless the aggregate
amount of WWC's and the Company's Losses claimed in respect of all such matters,
exceeds $5,000,000 in which event WWC and the Company shall be entitled to seek
indemnification under this SECTION 6.03 for the amount of all such Losses.

        6.4 Procedure.

            (a) Notice of Claim; Assumption of Defense by Indemnitor. In the
event that any Person hereto shall sustain or incur any Losses in respect of
which indemnification may be sought by such Person (the "Indemnitee") pursuant
to this Article 6, the Indemnitee shall assert a claim for indemnification by
giving prompt notice to the indemnifying party (the "Indemnitor") and shall
thereafter keep the Indemnitor reasonably informed with respect thereto;
provided that failure of the Indemnitee to give the Indemnitor notice as
provided herein shall not relieve the Indemnitor of any of its obligations
hereunder, except to the extent that the Indemnitor is materially prejudiced by
such failure. In case a claim is brought against any Indemnitee, the Indemnitor
shall have the right to assume, conduct and control the defense, compromise or
settlement thereof, by written notice to the Indemnitee of its intention to do
so within thirty (30) 




                                       24
<PAGE>   27
days after receipt of the notice, with counsel reasonably satisfactory to the
Indemnitee, at the Indemnitor's own expense, and thereupon to prosecute in the
name and on behalf of the Indemnitee any available cross-claims, counter-claims
or third-party claims arising with respect to the claim. If the Indemnitor shall
assume the defense of such claim, it shall not settle such claim unless such
settlement includes as an unconditional term thereof the giving by the claimant
or the plaintiff of a release of the Indemnitee, reasonably satisfactory to the
Indemnitee, from all liability with respect to such claim. As long as the
Indemnitor is contesting any such claim in good faith and on a timely basis, the
Indemnitee shall not pay or settle any such claim. Notwithstanding the
assumption by the Indemnitor of the defense of any claim as provided in this
SECTION 6.04 and without limiting the Indemnitor's right to assume, conduct and
control the defense, compromise or settlement thereof, the Indemnitee shall be
permitted to join in the defense of such claim and to employ counsel at its own
expense. Assumption by the Indemnitor of the defense of any claim shall not be
deemed a concession by the Indemnitor that it is required to indemnify the
Indemnitee for the subject matter of such claim.

            (b) Assumption of Defense by Indemnitee. If the Indemnitor shall
fail to notify the Indemnitee of its desire to assume the defense of any such
claim within the prescribed 30-day period set forth in SECTION 6.04(a), or shall
notify the Indemnitee that it will not assume the defense of any such claim,
then the Indemnitee may assume the defense of any such claim, in which event it
may do so in such manner as it may deem appropriate, and the Indemnitor shall be
bound by any determinations made in any litigation with respect to such claim or
any settlement thereof effected by the Indemnitee, provided that any such
determinations or settlement shall not affect the right of the Indemnitor to
dispute the Indemnitee's claim for indemnification.

            (c) Payments. Amounts payable by the Indemnitor to the Indemnitee in
respect of any Losses for which any Person is entitled to indemnification
hereunder shall be payable by the Indemnitor as incurred by the Indemnitee. Any
payments by any Indemnitor in indemnification hereunder shall be treated as
adjustments to the Purchase Price.

        6.5 Indemnity Sole Remedy. In the absence of fraud or of a suit seeking
specific performance as contemplated by this Agreement, the remedies provided to
WWC, the Company, HTL and the Investor by the foregoing provisions of this
Article 6 shall after the Closing Date be in lieu of any other remedies to which
the respective party is entitled at law or in equity for any breach or
noncompliance by a party with the provisions of this Agreement.

                                    ARTICLE 7

                                  MISCELLANEOUS

        7.1 Expenses. Each party shall bear its own expenses incident to the
negotiation, preparation, authorization and consummation of this Agreement and
the transactions contemplated hereby, including all fees and expenses of its
counsel and accountants, whether or not such transactions are consummated.




                                       25
<PAGE>   28
        7.2 Equitable Remedies. The parties hereto agree that irreparable damage
would occur in the event that any of the provisions of this Agreement were not
performed in accordance with the specific terms of the provisions or were
otherwise breached. It is accordingly agreed that the parties shall be entitled
to an injunction or injunctions to prevent breaches of this Agreement and to
enforce specifically the terms and provisions hereof in any court of the United
States or any state having jurisdiction, this being in addition to any other
remedy to which they are entitled at law or in equity. Each party agrees that it
will not assert, as a defense against a claim for specific performance, that the
party seeking specific performance has an adequate remedy at law.

        7.3 Notices. All notices, claims and other communications hereunder
shall be in writing and shall be made by hand delivery, registered or certified

the subject matter hereof and this Agreement may not be changed, modified,
altered or terminated except by an agreement in writing executed by the parties
hereto. Any waiver by any party of any of its rights under this Agreement or of
any breach of this Agreement shall not constitute a waiver of any other rights
or of any other or future breach.

        7.5 Remedies Cumulative. Except as otherwise provided herein, each and
all of the rights and remedies in this Agreement provided, and each and all of
the rights and remedies allowed at law and in equity in like case, shall be
cumulative, and the exercise of one right or remedy shall not be exclusive of
the right to exercise or resort to any and all other rights or remedies provided
in this Agreement or at law or in equity.

        7.6 Governing Law. This Agreement shall be construed in accordance with
and subject to the laws and decisions of the State of New York applicable to
contracts made and to be performed entirely therein.

        7.7 Counterparts. This Agreement may be executed in several counterparts
hereof, and by the different parties hereto on separate counterparts hereof,
each of which shall be an original; but such counterparts shall together
constitute one and the same instrument.

        7.8 Waivers. No provision in this Agreement shall be deemed waived
except by an instrument in writing signed by the party waiving such provision.

        7.9 Successors and Assigns. This Agreement shall be binding upon and
inure to the benefit of the parties hereto and to their respective successors
and assigns; provided, however, that except as set forth in the following
sentence or as otherwise expressly set forth in this 




                                       28
<PAGE>   31
Agreement neither the rights nor the obligations of either party may be assigned
or delegated without the prior written consent of the other parties. Upon thirty
(30) days prior written notice to WWC and the Company and subject to receipt of
all necessary regulatory approvals (but only if such regulatory approvals will
not delay in any way the Closing), the Investor may assign all or any portion of
their rights and obligations under this Agreement to HTL or any Subsidiary of
HTL so long as such assignee agrees in writing to be bound by the provisions of
this Agreement and the Shareholders Agreement. For purposes of this Section
7.09, the "Subsidiaries" of HTL shall be deemed to include Orange plc and any
Subsidiaries of Orange plc, provided, that at the time of any such assignment,
HTL owns not less than 45% of the outstanding voting securities of Orange plc.
In the event of any such assignment, HTL shall not be relieved of any of its
obligations under this Agreement.

        7.10 Further Assurances. Each of HTL and the Investor shall, at the
request of WWC or the Company, and WWC and the Company shall, at the request of
either of HTL or the Investor, from time to time, execute and deliver such other
assignments, transfers, conveyances and other instruments and documents and do
and perform such other acts and things as may be reasonably necessary or
desirable for effecting complete consummation of this Agreement and the
transactions herein contemplated.

        7.11 Disclosures.

            (a) Confidentiality. Each of HTL and the Investor and each of WWC
and the Company acknowledges and confirms in connection with the negotiation of
this Agreement and the execution hereof, during the period from the date hereof
through the Closing Date, the parties hereto will have furnished to one another
certain materials, information, data and other documentation ("Disclosures")
concerning their business, financial condition and operations which are
proprietary and confidential. Each party acknowledges the party disclosing such
Disclosures considers them secret and confidential and asserts a proprietary
interest therein. Accordingly, each of HTL and the Investor, on the one hand,
and each of WWC and the Company, on the other hand, covenants and agrees that it
shall maintain all Disclosures made by another party in strict confidence and
shall not use such Disclosures for its own benefit or disclose them to third
parties, except to its agents, representatives, bankers, investment bankers,
counsel and employees involved in evaluating the transactions contemplated by
this Agreement, its partners (and the partners or other security holders
thereof) or as otherwise required by law (including the requirement of WWC to
disclose such terms under the Securities Act, the Exchange Act or under the
rules of any securities exchange on which the securities of WWC are registered;
and including the requirement of HTL or any of its Affiliates to disclose such
terms under the securities laws of Hong Kong, or under the rules of the Hong
Kong Stock Exchange).

            (b) Public Announcements. No public announcement by any party hereto
with regard to the transactions contemplated hereby or the material terms hereof
shall be issued by any party without the mutual prior consent of the other
parties, except in the event the parties are unable to agree on a press release
and legal counsel for one party is of the opinion that such 




                                       29
<PAGE>   32
press release is required by law and such party furnishes the other parties a
written opinion of outside legal counsel, or other counsel reasonably acceptable
to the party being furnished such opinion, to that effect, then such party may
issue the legally required press release.

            (c) Non-Confidential Information. This Agreement shall not restrict
any party hereto from using information already known to it, to which it is
entitled under existing agreements, or information generally in the public
domain or any information coming into its possession after it becomes public
knowledge unless it became public knowledge through a breach of this Agreement.

        7.12 Termination.

            (a) Events Triggering Termination. This Agreement may be terminated
and the transactions contemplated hereby may be abandoned, without further
obligation of WWC, the Company, HTL or the Investor, at any time prior to the
Closing Date as follows:

                (i) by mutual written consent duly authorized by the boards of
directors of WWC, the Company, HTL and the Investor; or

                (ii) by WWC, the Company, HTL or the Investor if the Closing
Date shall not have occurred on or before March 31, 1998 or such later date, if
any, as WWC, the Company, HTL and the Investor shall agree in writing; provided,
that the party exercising such right is not in default of its obligations under
this Agreement in a manner which results in the failure to satisfy the
conditions to the transactions contemplated hereby of the other parties; or

                (iii) by WWC, the Company, HTL or the Investor if the
consummation of the transactions contemplated hereby shall be prohibited by a
final, non-appealable order, decree or injunction of a court of competent
jurisdiction, or if the FCC shall have by Final Order denied the application for
a Favorable Declaratory Ruling.

            (b) No Further Obligation. 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 that nothing herein will relieve any party
from liability for any breach of this Agreement.

        7.13 Jurisdiction; Consent to Service of Process. Each of HTL and the
Investor hereby irrevocably appoints United Corporate Services, Inc., at its
office at 10 Bank Street, White Plains, New York 10606, United States of
America, and the Company hereby irrevocably appoints United Corporate Services,
Inc., at its office at 10 Bank Street, White Plains, New York 10606 United
States of America, its lawful agent and attorney to accept and acknowledge
service of any and all process against it in any action, suit or proceeding
arising in connection with this Agreement or the Shareholders Agreement, and
upon whom such process may be served, with the same effect as if such party were
a resident of the State of New York and had been lawfully served with such
process in such jurisdiction, and waives all claim of error by reason of such




                                       30
<PAGE>   33
service, provided that in the case of any service upon such agent and attorney,
the party effecting such service shall also deliver a copy thereof to the other
party at the address and in the manner specified in SECTION 7.03. In the event
that such agent and attorney resigns or otherwise becomes incapable of acting as
such, such party will appoint a successor agent and attorney in New York,
reasonably satisfactory to the other party, with like powers. Each party hereby
irrevocable submits to the exclusive jurisdiction of the United States District
Court for the Southern District of New York and any court of the State of New
York located in the City of New York in any such action, suit or proceeding, and
agrees that any such action, suit or proceeding shall be brought only in such
court (and waives any objection based on forum non conveniens or any other
objection to venue therein), provided, however, that such consent to
jurisdiction is solely for the purpose referred to in this SECTION 7.13 and
shall not be deemed to be a general submission to the jurisdiction of said
courts or the State of New York other than for such purpose.

               IN WITNESS WHEREOF, the parties hereto have duly executed this
Agreement as of the date first above written.
