3. REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

         Except as set forth on a Schedule of Exceptions delivered by the
Company at each Closing, the Company hereby represents and warrants to Purchaser
as of the date of this Agreement, First Closing Date and each Option Closing
Date as follows:

         3.1 ORGANIZATION, GOOD STANDING AND QUALIFICATION. Each of the Company
and its Subsidiaries (as defined below) is a corporation or other entity duly
organized, validly existing and in good standing under the laws of the
jurisdiction of incorporation or formation as set forth on Schedule 3.1 and has
all requisite power and authority to own and operate its respective properties
and assets and to carry on its respective business as currently conducted and as
currently proposed to be conducted. The Company has all requisite corporate
power and authority to execute and deliver this Agreement and the Amended and
Restated Purchasers Rights Agreement in the form of Exhibit B attached hereto
(the "Purchasers Rights Agreement," and together with any other agreement
entered into in connection with this transaction, the "Related Agreements"), to
issue and sell the Shares and to carry out the provisions of this Agreement and
the Related Agreements. Each of the Company and its Subsidiaries is duly
qualified and is authorized to do business and is in good standing as a foreign
corporation or other entity in all jurisdictions in which the nature of its
activities and of its properties (both owned and leased) makes such
qualification necessary, except for those jurisdictions in which failure to do
so would not have a material adverse effect on the assets, liabilities,
business, results of operations, financial condition or prospects of the Company
and its Subsidiaries, taken as a whole (a "Material Adverse Effect"). Schedule
3.1 lists all the jurisdictions in which the Company is qualified as a foreign
corporation and the dates of such qualifications.

         3.2 SUBSIDIARIES. The Company does not own voting securities or other
similar interests of any corporation or other entity that is sufficient to
enable the company to elect a majority of the members of such corporation's or
other entity's Board of Directors or other governing body, except for those
corporations or other entities set forth on Schedule 3.1 (each a "Subsidiary"
and collectively, the "Subsidiaries"). All the outstanding shares of stock of
the Subsidiaries have been validly issued and are fully paid and non-assessable
and all such outstanding shares are owned directly by the Company free of any
lien or claim. Except as set forth of Schedule 3.1, neither the Company nor any
of its Subsidiaries is a participant in any joint venture, partnership or
similar arrangement.

         3.3 CAPITALIZATION; VOTING RIGHTS. The authorized capital stock of the
Company, immediately prior to the First Closing, will consist of 135,000,000
shares, of which 80,000,000 are shares of Common Stock, par value $.001 per
share, 5,043,706 shares of which are issued and outstanding and 791,748 shares
of which are reserved for future issuance to employees pursuant to the Stock
Option Plan (as hereinafter defined) and 55,000,000 are shares of Preferred
Stock, par value $.001 per share; 8,750,000 of which are designated Series B
Preferred Stock, 8,572,039 of which are issued and outstanding; 8,500,000 shares
of which are designated Series C Preferred Stock, 8,492,749 of which are issued
and outstanding; 2,225,000 of which are designated Series D Preferred Stock, not
more than 2,222,222 of which are issued and outstanding; 1,904,898 of which



                                       3

are designated Series E Preferred Stock, none of which are issued and
outstanding; and 30,000,000 of which are designated Series F Preferred Stock,
none of which are issued and outstanding. All issued and outstanding shares of
the Company's capital stock (a) have been duly authorized and validly issued,
(b) are fully paid and nonassessable, (c) were issued in compliance with all
applicable state and federal laws concerning the issuance of securities. The
rights, preferences, privileges and restrictions of the Preferred Stock are as

copy of the Company's Stock Option Plan (the "Stock Option Plan"). Schedule 3.3
sets forth a true and complete summary of all options issued under the Stock
Option Plan, including the holder, issue date, exercise price, vesting status
and expiration date of such option. Other than the 791,748 shares reserved for
issuance under the Stock Option Plan, the Options issued pursuant to the Stock
Option Plan as set forth on Schedule 3.3 and 115,000 outstanding warrants to
purchase 1,409,734 shares of Common Stock (the "Existing Warrants"), and except
as may be granted pursuant to this Agreement and the Related Agreements, there
are no outstanding options, warrants, rights (including conversion or preemptive
rights and rights of first refusal), proxy or shareholder agreements, or
agreements of any kind for the purchase or acquisition from the Company or any
Subsidiary of any of their securities. Except as described in this Agreement or
set forth in Schedule 3.3, (x) there are no outstanding obligations of the
Company or any of its Subsidiaries to repurchase, redeem or otherwise acquire
any securities of the Company or any voting or equity securities or interests of
any subsidiary of the Company, (y) there is no voting trust or other agreement
or understanding to which the Company or any of its Subsidiaries is a party or
is bound with respect to the voting of the capital stock or other voting
securities of the Company or any of its Subsidiaries and (z) there are no other
options, calls, warrants or other rights, agreements, arrangements or
commitments of any character relating to the issued or unissued capital stock of
the Company or any of its Subsidiaries to which the Company or any of its

Agreement and the Restated Certificate, the Shares will be validly issued, fully
paid and nonassessable; provided, however, that such shares may be subject to
restrictions on transfer under the Purchasers Right Agreement or under state
and/or federal securities laws or as otherwise required by such laws at the time
a transfer is proposed. Schedule 3.3 sets forth as of the date hereof the name
of each person or entity owning any of the Company's outstanding equity
securities and the number and class of equity security owned by each such person
or entity.

all obligations of the Company hereunder and thereunder as of each Closing and
the authorization, sale, issuance and delivery of the Shares (including the
Option Shares) has been taken or will be taken prior to the First Closing. The
Agreement and the Related Agreements, when executed and delivered, will be valid
and binding obligations of the Company enforceable in accordance with their
terms, except (a) as limited by applicable bankruptcy, insolvency,
reorganization, moratorium or other laws of general application affecting
enforcement of creditors' rights; (b) general principles of equity that restrict
the availability of equitable remedies; and (c) to the extent that the
enforceability of the indemnification provisions in Section 2.5 of the

             (B) The Company has delivered to Purchaser an unaudited balance
sheet (the "Statement Date Balance Sheet") of the Company and its Subsidiaries
as at March 31, 1999 (the "Statement Date") and unaudited statement of income
and cash flows of the Company and its subsidiaries for the three months ending
on the Statement Date (the "Statement Date Income Statement" and "Statement Date
Cash Flow Statement" respectively, and collectively with the Statement Date
Balance Sheet and all audited and unaudited financial statements included in the
SEC Reports, the "Financial Statements"). The Financial Statements, together
with the notes thereto, have been prepared in accordance with generally accepted

periods indicated, except as disclosed therein, and present fairly the
consolidated financial position of the Company and its Subsidiaries as of the
respective dates presented therein and the consolidated results of operations
and cash flows of the Company and its Subsidiaries for the respective periods
presented therein; provided, however, that the unaudited financial statements

             (C) Except as set forth in Schedule 3.7(c), neither the Company nor
any of its Subsidiaries is, nor to the Company's knowledge is any other party to
any Contract, in material default under, or in material breach or material
violation of, any Contract and, to the knowledge of the Company, no event has
occurred which, with the giving of notice or passage of time or both would
constitute a material default by the Company under any Contract. Other than
Contracts which have terminated or expired in accordance with their terms, each
of the Contracts is valid and binding obligation of the Company enforceable
against the Company in accordance with its terms (subject to the effects of
bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and
other similar laws relating to or affecting creditors' rights generally, general
equitable principles (whether considered on a proceeding in equity or at law)
and an implied covenant of good faith and fair dealing) and is in full force and
effect. No event has occurred which either entitles, or would, on notice or
lapse of time or both, entitle the holder of any indebtedness of the Company or
any of its Subsidiaries to accelerate or which does accelerate the maturity of
any indebtedness for borrowed money of the Company or any of the Subsidiaries.

             (D) Except as set forth on Schedule 3.7(d), neither the Company nor
any Subsidiary has (i) declared or paid any dividends, or authorized or made any

liabilities, agreements, understandings, instruments, contracts and proposed
transactions involving the same person or entity (including persons or entities
the Company or any Subsidiary has reason to believe are affiliated therewith)
shall be aggregated for the purpose of meeting the individual minimum dollar
amounts of such subsections.

Subsidiary is a guarantor or indemnitor of any indebtedness of any other person,
firm or corporation.

             (A) any change in the assets, liabilities, financial condition or
operations of the Company and its Subsidiaries from that reflected in the

owns or possesses sufficient legal rights to all patents, trademarks, service
marks, trade names, copyrights, trade secrets, licenses, information and other
proprietary rights and processes necessary for its respective business as now

patents, trademarks, service marks, trade names, copyrights or trade secrets or
other proprietary rights of any other person or entity. Neither the Company nor
any of its Subsidiaries is aware that any of its employees is obligated under

administrative agency, that would interfere with their duties to the Company or
any of its Subsidiaries or that would conflict with the Company's or any of its
Subsidiaries' business as presently proposed to be conducted. Neither the
execution nor delivery of this Agreement, nor the carrying on of the Company's
or any of its Subsidiaries' business by the employees of the Company or its
Subsidiaries, nor the conduct of the Company's or any of its Subsidiaries'
business as currently proposed, will conflict with or result in a breach of the
terms, conditions or provisions of, or constitute a default under, any contract,
covenant or instrument under which any employee is now obligated. Neither the
Company nor any of its Subsidiaries believes it is or will be necessary to
utilize any inventions, trade secrets or proprietary information of any of its
employees made prior to their employment by the Company or any of its
Subsidiaries, except for inventions, trade secrets or proprietary information
that have been assigned to the Company or any of its Subsidiaries.

         3.12 COMPLIANCE WITH OTHER INSTRUMENTS. Neither the Company nor any of
its Subsidiaries is in violation or default of (i) the Restated Certificate or
Bylaws, (ii) any Contract or (iii) of any judgment, decree, order, writ, or any
statute, rule or regulation, including, without limitation, requirements of the
FCC or any state regulatory agency applicable to the Company or any Subsidiary,
except for such violations or defaults in respect of clauses (ii) or (iii) which
would not, individually or in the aggregate, be reasonably expected to have a
Material Adverse Effect. The execution, delivery, and performance of this
Agreement, and the Related Agreements, and the issuance and sale of the Shares
pursuant hereto, will not, with or without the passage of time or giving of
notice, result in any violation, or be in conflict with or constitute a default
under (i) the Restated Certificate or Bylaws, (iii) any Contract or (iii) any
judgment, decree, order, writ or any statute, rule or regulation including,
without limitation, requirements of the FCC or any state regulatory agency
applicable to the Company or any Subsidiary. The execution, delivery and
performance of this Agreement, and the Related Agreements, and the issuance and
sale of the Shares pursuant hereto, will not result in the creation of any
mortgage, pledge, lien, encumbrance or charge upon any of the properties or
assets of the Company and its Subsidiaries or the suspension, revocation,
impairment, forfeiture or nonrenewal of any permit license, authorization or
approval applicable to the Company, its business or operations or any of its
assets or properties.

         3.13 LITIGATION. Except as set forth on Schedule 3.13, there is no
action, suit, proceeding or investigation pending or to the Company's knowledge
currently threatened against the Company or any Subsidiary. The foregoing

therefor known to the Company) involving the prior employment of any of the
Company's or any Subsidiary's employees, their use in connection with the
Company's or any Subsidiary's business of any information or techniques

         3.20 EMPLOYEE BENEFIT PLANS.

              (A) Schedule 3.20 contains a true and complete list of each

rules and regulations and neither the Company nor any of its Subsidiaries has
incurred any material tax, fine, lien, penalty or other liability imposed by
ERISA, the Code or other applicable law, rule and regulations; and (ii) each
Company Plan which is intended to be qualified within the meaning of Code
section 401(a) has received a favorable determination or if such plan is a
prototype plan, the prototype plan has received a favorable determination
letter, in all material respects, to its qualifications, or is in a form in
which the Internal Revenue Service consider the terms of such Company Plan to be
qualified without the need to receive such a letter, and subsequent to that term
nothing has occurred, whether by action or failure to act, that could reasonably
be expected to cause the loss of such qualification.

              (D) No Company Plan is (i) subject to Title IV or ERISA or (ii)
a "multiemployer plan" (as such term is defined in section 3(37) of ERISA) and
neither the Company nor any of its Subsidiaries has incurred any withdrawal
liability or termination liability with respect to any such plan that remains
unsatisfied. The Company has not engaged in, and is not a successor or parent
corporation to any entity that has engaged in, a transaction described in

              (E) Except as disclosed on Schedule 3.21(e), with respect to any
Company Plan, no actions, suits or claims (other than routine claims for
benefits in the ordinary course) are pending or, to the knowledge of the Company
or any of its Subsidiaries, threatened or reasonably expected to arise.

              (F) Except as disclosed on Schedule 3.21(f), no Company Plan
exists that could result in the payment to any present or former employee of the
Company or its Subsidiaries of any money or other property or accelerate or
provide any other rights or benefits to any present or former employee of the
Company or its Subsidiaries as a direct result of the transaction contemplated
by this Agreement, whether or not such payment would constitute a parachute

         3.21 INSURANCE. Schedule 3.21 sets forth a true and complete summary of
each insurance policy pertaining to the assets or operations of the Company and

to any claim or potential claim filed under any such policies.

         3.22 BOOKS AND RECORDS. The books of account, stock records, minute

on a consolidated basis, including annual income, net profits and cash flows for
each year of the five-year period ending 2003 (the "Projections"). The

performance of the Company and its Subsidiaries. All material assumptions used
in the preparation of the Projections are set forth in the notes thereto.
Notwithstanding the foregoing, no representation is made that the projections
will be attained.

         3.25 LICENSES. Schedule 3.25 sets forth a list of each license used by
the Company or any of its Subsidiaries and which is material to the conduct and
operation of the Company business (the "Licenses"). True and correct copies of
the Licenses and all amendments thereto to the date hereof, have been delivered

Company and its Subsidiaries have complied in all material respects with the

revocations of the Licenses which, individually or in the aggregate, would
reasonably be expected to have a Material Adverse Effect. All fees due and
payable from the Company or any of its Subsidiaries to governmental authorities
pursuant to the Licenses have been paid. All reports required of the Company or

timely filed and are accurate and complete. The Company believes it can obtain,
without undue burden or expense, any similar authority for the conduct of its
business as planned to be conducted. Except as specified in Schedule 3.25, no
registrations, filings, applications, notices, transfers, consents, approvals,
audits, qualifications, waivers or other action of any kind is required by
virtue of the execution and delivery of this Agreement or any Related Agreement,
or of the consummation of the transactions contemplated hereby or thereby (a) to
avoid the loss of any license or any asset, property or right pursuant to the
terms thereof or the violation or breach of any law applicable thereto, or (b)
to enable the Company and its Subsidiaries to hold and enjoy the same after the
Closing Date in the conduct of its business as conducted immediately prior to
the Closing Date. The Company has filed with the FCC an application for
authorization to provide international telecommunications service and no party
has opposed the granting of such application.

         3.27 CUSTOMERS. No single customer of the Company accounted for more
than five percent (5%) of the Company's consolidated net sales for 1998, and the
Company does not anticipate any single customer accounting for more than five
percent (5%) of the Company's consolidated net sales in 1999. Schedule 3.27 sets
forth as of March 31, 1999, the total number of lines in service.

         3.28 YEAR 2000 COMPLIANCE. The Company has implemented a Year 2000
readiness program to evaluate date-sensitive material hardware and software
systems used by the Company to determine if such systems are Year 2000 Compliant
or will be Year 2000 Compliant by December 31, 1999, and, based on that, has
formulated a plan to make such systems Year 2000 Compliant, as more particularly
described on Schedule 3.28 (the "Year 2000 Compliance Plan"). The term "Year
2000 Compliant" as used herein means that under the conditions of the Company's
internal testing the computer systems at issue will neither cause any abnormal
termination of performance nor generate inconsistent results when processing
date data from, into, and between the twentieth and twenty-first centuries,
including the years 1999 and 2000, and leap year calculations. The Company
represents that it is using commercially reasonable efforts to achieve the goals
set forth in its Year 2000 Compliance Plan, and that if such goals are achieved,
the material hardware and software systems used by the Company will be Year 2000
Compliant by December 31, 1999. The Company does not control third party
hardware or software systems that may interfere or exchange data with the
Company's material hardware and software systems and the foregoing
representation specifically excludes any representation that such third party
hardware and software systems are Year 2000 Compliant.

         3.29 NO BROKER. Except as set forth in Schedule 3.29, neither the
Company nor any of its Subsidiaries has employed any broker or finder, or
incurred any liability for any brokerage or finders' fees or any similar fees or
commissions in connection with the transactions contemplated by this Agreement.

         3.30 DISCLOSURE. No representation or warranty contained in this
Agreement or any statement or information contained in any schedule, exhibit,
certificate, written statement, document or instrument, or other information
attached to, delivered or required to be delivered pursuant to this Agreement
contains any untrue statement of material fact or omits to state a material fact
necessary in order to make the statements contained herein not misleading or
necessary in order to fully and fairly provide the information required to be
provided in any such document.
