knowledge of the Company, is there any basis for any valid claim of default or
violation under any Contract. To the knowledge of the Company, no other party to
any of such Contracts is in default in any material respect thereunder nor does
there exist any event or condition, which upon the giving of notice or the lapse

efforts to ensure that its capital stock will not, constitute a United States
real property interest as that term is defined in Section 897(c)(1)(A)(ii) of

representation is based on a determination by the Company that the Company is
not and has not been a United States real property holding corporation (as that
term is defined in Section 897(c)(2) of the Code) ("USRPHC") during the five (5)
year period preceding the date of this Agreement. From time to time, upon the
request of any Purchaser, the Company shall make a determination as to its

512(b)(2) and 512(b)(3), respectively, in calculating unrelated business taxable
income and only such dividends, interest, capital gains and losses, and rents
and royalties that are not included under Section 512(b)(4) of the Code in
calculating unrelated business taxable income.

         3.11 Not a Qualified Small Business. The Company does not qualify as a
"Qualified Small Business" as defined in Section 1202(d) of the Code.

         3.12 Subsidiaries. Schedule 3.12 sets forth the ownership structure of

or equity interests of any of the Companies to which the Company or any of its
Subsidiaries is a party.

the appropriate governmental entity or an instrumentality thereof to such of the
Companies identified in Schedule 3.18 as holding such License and recorded with
the appropriate government entity in accordance with all applicable Legal

Each of the Companies is in compliance in all material respects with such

is no pending claim under any insurance policy to which any of the Companies is
an insured or beneficiary or any fact or circumstance reasonably likely to give
rise to such a claim.

         3.21 Taxes.

               (a) The Companies have filed all federal, state, departmental,
municipal and foreign Tax returns required by law to be filed by them other than
such filings, the failure of which to have been made, would not reasonably be
likely to result in the imposition of significant penalties on any of the
Companies. Except as set forth on the Financial Statements, and except for taxes
the failure of which to pay would not reasonably be likely to result in the
imposition of significant penalties on any of the Companies, each of the
Companies has paid all such taxes that have already become due and payable. The
provisions shown on the Financial Statements are adequate to reflect any
material amount of unpaid Taxes of the Companies due or to become due with
respect to fiscal periods ended on or before the date of the Financial
Statements. As of the date hereof, there is no claim or assessment pending
against the Company or any of the other Companies, based on a failure to pay
Taxes and no basis exists for any such claim.

               (b) The Company is not aware of and, to the Company's knowledge,
there are no circumstances which, either by passage of time or issuance of an
assessment binding on any of the Companies to pay any Tax or contribution, may
give rise to any type of dispute with any Tax authority in relation to any Tax
obligation or liability.

Employee Relations.

               (a) Except as set forth on Schedule 3.22(a), none of the

agreement which is not terminable at will in accordance with the laws of the
jurisdictions in which it operates. Except as set forth on Schedule 3.22(a),
there are no disputes currently subject to any grievance procedure, arbitration
or litigation under such collective bargaining agreements or employment
agreements nor is there any default under any such agreements, by any of the
Companies or to the knowledge of the Company, any other party thereto.

               (b) Schedule 3.22(b) sets forth all employees and directors of
the Company and their remuneration rates, applicable benefits and the applicable
term of their employment.

         3.23 Employee Benefits.

its employees or any director, (ii) been made the subject of representation or
similar communication by any of the Companies to their employees or directors or

               (c) Each of the Companies has made all requisite pension and

from vendors that on and following January 1, 2000, (i) its computer systems and
(ii) equipment containing embedded microchips (including systems and equipment
supplied by others or with which the systems of such Company interface) will
function properly. The cost to each of the Companies of the reasonably
foreseeable consequences of the Year 2000 to the respective company resulting
from the failure of its systems cannot be reasonably expected to have a Material
Adverse Effect. Each of the Companies has complied with the Year 2000
requirements, if any, established by the corresponding authorities.

         3.27 Broker's Fees. Except for any fees owed to Lehman Brothers,
Donaldson Lufkin & Jenrette and TD Securities, for which the Purchasers have no
liability, the Company has not employed any broker, finder, consultant or
intermediary in connection

                                       10
<PAGE>   15

with the transactions contemplated by the Transaction Documents that would be
entitled to a broker's, finder's or similar fee or commission in connection
therewith.

         3.28 Foreign Corrupt Practices Act. The Company represents that (i) it
has not taken any action which is or could be deemed to be a violation of the
Foreign Corrupt Practices Act in respect of any of the Companies; (ii) it is not
aware of any action or conduct which could be deemed to be a violation of the
Foreign Corrupt Practices Act in respect of any of the Companies and (iii) none
of its managers, officers, directors, employees, stockholders, members, agents
or representatives has offered, given, paid, authorized the payment of, or
promised, directly or indirectly, any money, gift, promise or other thing of
value to any Foreign Official (or to any other Person while knowing it will be
offered, given or promised to a Foreign Official) for any purpose including, by
way of example but not limitation, influencing any act or decision of such
Person acting in their official capacity, inducing such Person to do or omit to
do any action in violation of their lawful duty, inducing such Person to use
their influence with the government of the Republic of Argentina, the Republic
of Peru, the Republic of Colombia, the Republic of Venezuela, the Republic of
Uruguay, the Republic of Chile, the Federative Republic of Brazil or any other
government or any instrumentality thereof to affect or influence any act or

Companies or their stockholders or members to obtain or retain business for or
with, or in directing business to, any Person.

         3.29 Offering. Subject to the accuracy of the Purchasers'
representations in Section 4 hereof, the offer, sale and issuance of the Shares,
the Warrants, the Warrant Shares and the Conversion Shares constitute
transactions exempt from the registration requirements of Section 5 of the
Securities Act of 1933, as amended (the "Securities Act") and state Blue Sky
laws.

         3.30 Spectrum Allocation. The spectrum allocation held by or available
for use by each of the Companies is reasonably sufficient to enable such of the
Companies to satisfy its current business plan as presented to the Purchasers
except where the failure to have such allocation will not have a Material
Adverse Effect on such of the Companies; provided that in respect of the
Brazilian Companies, in the event any such Brazilian Company needs additional
spectrum to satisfy its current business plan objectives, the Company reasonably
believes that such spectrum should be available from ANATEL so long as such
Brazilian Company has complied with its existing license obligations.

SECTION 4.1 AUTHORIZED CAPITAL.

          (a) The Corporation shall be authorized to issue two classes of stock
to be designated respectively "Common Stock" and "Preferred Stock." The
aggregate number of shares which the Corporation shall have the authority to
issue is one hundred eighty seven million two hundred sixty eight thousand eight
hundred forty two (187,268,842); the total number of shares of Common Stock
shall be one hundred eight

<PAGE>   27

million six hundred thirty four thousand four hundred twenty one (108,634,421),
with a par value of $.0001 per share, and the total number of shares of
Preferred Stock shall be seventy eight million six hundred thirty four thousand
four hundred twenty one (78,634,421), with a par value of $.0001 per share. Such
Preferred Stock may be issued in series.

          (b) Subject to the voting requirements set forth in Section
4.2(b)(iii), the Corporation's board of directors shall have the authority,
without stockholder action, to determine the preferences, limitations and
relative rights of any Preferred Stock (whether in a series or as a class),
including without limitation the following: (i) the designation of any series of
Preferred Stock; (ii) unlimited, special, conditional, or limited voting rights,
or no right to vote; except that no condition, limitation, or prohibition on
voting shall eliminate any right to vote provided by the Delaware General
Corporation Law; (iii) redemption rights; (iv) conversion rights, (v)
distribution or dividend rights, including the determination of whether such
rights are cumulative, non-cumulative or partially cumulative, and (vi)
preference rights over any other class or series of shares with respect to
distributions, including dividends and distributions upon the dissolution of the
Corporation.

          (c) Common Stock shall be divided into one hundred six million six
hundred sixty six thousand six hundred sixty seven (106,666,667) shares of
voting common stock (the "Voting Common Stock") and one million nine hundred
sixty seven thousand seven hundred fifty four (1,967,754) shares of non-voting
Common Stock (the "Non-Voting Common Stock, and together, the "Common Stock").
Except as otherwise required by law, the Non-Voting Common Stock shall not be
entitled to vote on any matter on which the Stockholders of the Corporation
shall be entitled to vote; and shares of Non-Voting Common Stock shall not be
included in determining the number of shares voting or entitled to vote on any
such matters. Except for the difference in voting rights, both the Voting Common
Stock and the Non-Voting Common stock shall be identical in their rights.

SECTION 4.2 DESIGNATION OF PREFERRED STOCK.

     Thirty one million (31,000,000) of the authorized shares of Preferred Stock
are hereby designated as "Series A Preferred Stock" (the "Series A Preferred"),
forty one million six hundred sixty six thousand six hundred sixty seven
(41,666,667) of the authorized shares of Preferred Stock are hereby designated
as "Series B Preferred Stock" (the "Series B Preferred") and one million nine
hundred sixty seven thousand seven hundred fifty four (1,967,754) of the
authorized shares of Preferred Stock are hereby designated as "Series B-1
Preferred Stock" (the "Series B-1 Preferred," and together with the Series B
Preferred, the "Series B/B-1 Preferred"). Except for the differences in voting
and conversion rights set forth herein, both the Series B Preferred and the
Series B-1 Preferred shall be identical in their rights. The Series A Preferred
and the Series B/B-1 Preferred are hereinafter collectively referred to as the
"Series Preferred." The rights, preferences, privileges, restrictions and other
matters relating to the Series Preferred are as follows:

                                       2
<PAGE>   28

          (a) DIVIDEND RIGHTS.

               (i) Declared Dividends. Holders of the Series Preferred, in
preference to the holders of Common Stock and any other stock of the Corporation
that is not by its terms expressly senior in right of payment to the Series
Preferred (collectively, "Junior Stock"), shall be entitled to receive
dividends, when and as declared by the board of directors, but only out of funds
that are legally available therefor. In addition, in the event that the
Corporation declares or pays any dividends upon the Common Stock (whether
payable in cash, securities or other property) other than dividends payable
solely in shares of Common Stock, the Corporation shall also declare and pay to
the holders of the Series Preferred at the same time that it declares and pays
such dividends to the holders of the Common Stock, the dividends which would
have been declared and paid with respect to the Common Stock issuable upon
conversion of the Series Preferred had all of the outstanding Series Preferred
been converted immediately prior to the record date for such dividend, or if no
record date is fixed, the date as of which the record holders of Common Stock
entitled to such dividends are to be determined. The Corporation shall not
declare dividends on one Series of Preferred Stock and not on each other Series
of Preferred Stock.

               (ii) Preference. So long as any of the Series Preferred remains
outstanding, without the prior written consent of the holders of sixty-six and
two-thirds percent (66 2/3%) of the outstanding shares of the Series Preferred
(the "Required Holders"), the Corporation shall not, nor shall it permit any
Subsidiary to, redeem, purchase or otherwise acquire directly or indirectly any
Junior Stock, nor shall the Corporation directly or indirectly pay or declare
any dividend or make any distribution upon any Junior Stock. The provisions of
this Section 4.2(a)(ii) shall not, however, apply to (i) the acquisition of
shares of any Junior Stock in exchange for shares of any other Junior Stock,
(ii) the payment of cash dividends on the Common Stock to the extent that
equivalent dividends are paid on the Series Preferred as provided above, or
(iii) any repurchase of any Reserved Employee Stock from former employees,
directors or consultants in connection with termination of employment or service
as a director or consultant that is approved by the Corporation's board of
directors.

          (b) VOTING RIGHTS.

               (i) Generally. Except as otherwise provided herein or as required
by law, the Series Preferred shall vote with the shares of the Common Stock of
the Corporation (and not as a separate class) at any annual or special meeting
of stockholders of the Corporation, and may act by written consent in the same
manner as the Common Stock, in either case upon the following basis: each holder
of shares of the Series Preferred shall be entitled to such number of votes as
shall be equal to the whole number of shares of Common Stock into which such
holder's aggregate number of shares of the Series Preferred are convertible
(pursuant to Section 4.2(e) below) immediately after the close of business on
the record date fixed for such meeting or the effective date of such written
consent.

                                       3
<PAGE>   29

               (ii) Except as specifically set forth in this Article Four, or as
otherwise required by law, each outstanding share of Series B-1 Preferred shall
not be entitled to vote on any matter on which the stockholders of the
Corporation shall be entitled to vote; and shares of Series B-1 Preferred shall
not be included in determining the number of shares voting or entitled to vote
on any such matters.

               (iii) Class Vote Requirement. Without the affirmative vote of the
Required Holders, the Corporation shall not (i) create, issue or authorize the
issuance of any additional Common Stock or Preferred Stock or create or
authorize any new class or series of the Corporation's capital stock (except for
issuances of Reserved Employee Stock, issuances upon conversion of Preferred
Stock, and issuances in connection with strategic transactions involving the
Corporation and the non-affiliates of the Corporation approved by the
Corporation's board of directors, the primary purpose of which is other than to
raise funds for the Corporation (including (1) joint ventures, manufacturing,
marketing or distribution arrangements or (2) technology transfer or development
arrangements)); (ii) amend this Certificate of Incorporation or the
Corporation's Bylaws; (iii) engage in (1) any merger, consolidation, business
combination, recapitalization, or reorganization in which (A) the stockholders
of the Corporation immediately prior to such transaction own capital stock
representing less than seventy percent (70%) of the surviving company's voting
power in the election of directors immediately after such transaction or (B) the
stockholders of the Corporation immediately prior to such transaction do not own
substantially the same proportion of capital stock of the surviving company
after the transaction as they owned of the Corporation immediately prior to the
transaction (a "Disproportionate Change"); provided, however, that any change in
a stockholder's ownership percentage of less than ten percentage points shall
not be deemed to be a Disproportionate Change, (2) a liquidation or sale of
substantially all of the assets by the Corporation or any of its subsidiaries
outside the ordinary course of business, or (3) a purchase of substantial assets
by the Corporation or any of its subsidiaries outside the ordinary course of
business; (iv) engage in any business other than telecommunications and
multimedia communications services, including but not limited to data, voice or
video transmission, cable, IP telephony, MMDS, Internet access or any other
telecommunications service using wireless, wireline, fiber, LMDS or broadband
access or any other technology, and also including any Internet content
business; (v) increase the amount of Reserved Employee Stock above twelve
percent (12%) of the Corporation's Common Stock Deemed Outstanding; or (vi)
engage in any transaction with an affiliate of the Corporation, except for
transactions involving wholly-owned subsidiaries, that is not approved by a
majority of the Corporation's disinterested directors.

          (c) LIQUIDATION RIGHTS.

               (i) Liquidation Value. Upon any liquidation, dissolution or
winding up of the Corporation, whether voluntary or involuntary, before any
distribution or payment shall be made to the holders of any Junior Stock or
Common Stock, (i) first, the holders of the Series B/B-1 Preferred shall be
entitled to be paid out of the assets of the Corporation an amount with respect
to each share of the Series B/B-1 Preferred

                                       4
<PAGE>   30

equal to the sum of (A) the Original Series B/B-1 Issue Price (as defined below)
plus (B) all declared but unpaid dividends thereon (the "Series B/B-1
Liquidation Value") and (ii) second, after the payment of the full liquidation
preference of the Series B/B-1 Preferred, the holders of the Series A Preferred
shall be entitled to be paid out of the assets of the Corporation an amount with
respect to each share of the Series A Preferred equal to the sum of (A) the
Original Series A Issue Price (as defined below), plus (B) all declared but
unpaid dividends thereon (the "Series A Liquidation Value"). The "Original
Series A Issue Price" shall be Three Dollars ($3.00) per share, as appropriately
adjusted for any future stock splits, stock combinations, stock dividends or
similar transactions affecting the Series A Preferred. The "Original Series
B/B-1 Issue Price" shall be Six Dollars ($6.00) per share, as appropriately
adjusted for any future stock splits, stock combinations, stock dividends or
similar transactions affecting the Series B/B-1 Preferred.

               (ii) Participation. After the payment of the full liquidation
preference of the Series Preferred as set forth in Section 4.2(c)(i) above, the
remaining assets of the Corporation legally available for distribution, if any,
shall be distributed to the holders of Junior Stock entitled to a preference
over the Common Stock and, thereafter, to the holders of Common Stock. The
holders of the Series Preferred shall be entitled to participate in
distributions to holders of the Common Stock such that, giving effect to all
distributions pursuant to Section 4.2(c)(i), the holders of the Series Preferred
receive aggregate distributions equal to the greater of (A) the Series A
Liquidation Value (in the case of the Series A Preferred) or the Series B/B-1
Liquidation Value (in the case of the Series B/B-1 Preferred), or (B) the
amounts that such holders would have received if the Series Preferred had been
converted into Common Stock immediately prior to such liquidation, dissolution
or winding up of the Corporation.

               (iii) Liquidation Events. At the option of the Required Holders,
the following events shall be considered a liquidation for purposes of Section
4.2(c).

                    (A) any (1) merger, consolidation, business combination,
reorganization or recapitalization of the Corporation that involves a
Disproportionate Change; provided, however, that any change in a stockholder's
ownership percentage of less than ten percentage points shall not be deemed to
be a Disproportionate Change; or (2) transaction or series of related
transactions in which capital stock representing in excess of thirty percent
(30%) of the Corporation's voting power in electing the board of directors is
transferred (an "Acquisition"); or

                    (B) a sale, lease or other disposition of all or
substantially all of the assets of the Corporation (an "Asset Transfer").

               (iv) Proportionate Payments. If, upon any liquidation,
dissolution or winding up, the assets of the Corporation shall be insufficient
to make payment in full to all holders of the Series Preferred, then such assets
shall be distributed first, among the holders of the Series B/B-1 Preferred at
the time outstanding, ratably in proportion to the full amounts to which they
would otherwise be

                                       5
<PAGE>   31

entitled and second, any remaining assets shall be distributed among the holders
of the Series A Preferred at the time outstanding, ratably in proportion to the
full amounts to which they would otherwise be entitled.

          (d) REDEMPTION RIGHTS.

               (i) Scheduled Redemptions. Unless a holder of Series Preferred
elects otherwise in accordance with Section 4.2(d)(iii) below, on January 26,
2005, the Corporation shall redeem thirty three and one-third percent (33"%) of
the then-outstanding shares of each of the Series A Preferred and the Series
B/B-1 Preferred held by such holder; on January 26, 2006, the Corporation shall
redeem fifty percent (50%) of the then-outstanding shares of each of the Series
A Preferred and the Series B/B-1 Preferred held by such holder; and shall redeem
all remaining shares of the Series A Preferred and the Series B/B-1 Preferred
held by such holder on January 26, 2007 (the "Scheduled Redemption Dates"), at a
price per share equal to the Series A Liquidation Value or the Series B/B-1
Liquidation Value, respectively.

               (ii) Redemption Payments. For each share of the Series Preferred
which is to be redeemed hereunder, the Corporation shall be obligated on the
Scheduled Redemption Date to pay to the holder thereof (upon surrender by such
holder at the Corporation's principal office of the certificate representing
such share) an amount in cash equal to the Series A Liquidation Value or the
Series B/B-1 Liquidation Value, as applicable. If the funds of the Corporation
legally available for redemption of the Series Preferred on any Scheduled
Redemption Date are insufficient to redeem the total number of shares to be
redeemed on such date, those funds which are legally available shall be used to
redeem the maximum possible number of shares pro rata among the holders of the
Series Preferred to be redeemed based upon the aggregate Liquidation Value of
such shares of the Series Preferred held by each such holder. At any time
thereafter when additional funds of the Corporation are legally available for
the redemption of the Series Preferred, such funds shall immediately be used to
redeem the balance of the shares which the Corporation has become obligated to
redeem on any Scheduled Redemption Date but which it has not redeemed.

               (iii) Notice of Redemption. Except as otherwise provided herein,
the Corporation shall mail written notice of each redemption of the Series
Preferred to each record holder thereof not more than 60 nor less than 30 days
prior to the Scheduled Redemption Date (the "Corporation's Notice"). Any holder
of the Series Preferred may elect not to participate in the redemption on any
Scheduled Redemption Date by providing written notice to the Corporation of its
election not to have its shares of Preferred Stock redeemed within 10 days after
receipt of the Corporation's Notice. The holders of the Series Preferred to be
redeemed shall in any event have the right to convert any or all of their shares
into Common Stock at any time prior to the close of business on any Scheduled
Redemption Date. In case fewer than the total number of shares represented by
any certificate are redeemed, a new certificate representing the number of
unredeemed shares shall be issued to the holder thereof without cost to such

                                       6
<PAGE>   32

holder within five business days after surrender of the certificate representing
the redeemed shares.

               (iv) Other Redemptions or Acquisitions. The Corporation shall
not, nor shall it permit any Subsidiary to, redeem or otherwise acquire any
shares of the Series Preferred, except as expressly authorized herein or
pursuant to a purchase offer made pro rata to all holders of the Series
Preferred on the basis of the aggregate Liquidation Value of the shares of the
Series Preferred owned by each such holder. If the assets of the Corporation
shall be insufficient to make payment in full to all holders whose shares of
Series Preferred are being redeemed or otherwise acquired, such assets shall be
used first to redeem shares of Series B/B-1 Preferred, ratably in proportion to
the redemption price for the shares that such holders otherwise would have been
entitled to redeem, and second, any remaining assets shall be used to redeem
shares of Series A Preferred, ratably in proportion to the redemption price for
the shares that such holders otherwise would have been entitled to redeem.

          (e) CONVERSION RIGHTS - CONVERSION OF SERIES PREFERRED INTO COMMON
STOCK.

     The holders of the Series Preferred shall have the following rights with
respect to the conversion of the Series Preferred into shares of Common Stock:

               (i) Optional Conversion into Common Stock. Subject to and in
compliance with the provisions of this Section 4.2(e), any shares of the Series
Preferred may, at the option of the holder, be converted at any time into
fully-paid and nonassessable shares of Common Stock (either Voting Common Stock,
in the case of Series A Preferred or Series B Preferred, or Non-Voting Common
Stock, in the case of Series B-1 Preferred). The number of shares of Common
Stock to which a holder of the Series A Preferred shall be entitled upon
conversion shall be the product obtained by multiplying the "Series A Conversion
Rate" then in effect (determined as provided in Section 4.2(e)(ii)) by the
number of shares of the Series A Preferred being converted. The number of shares
of Common Stock to which a holder of the Series B/B-1 Preferred shall be
entitled upon conversion shall be the product obtained by multiplying the
"Series B/B-1 Conversion Rate" then in effect (determined as provided in Section
4.2(e)(ii)) by the number of shares of the Series B/B-1 Preferred being
converted.

               (ii) Series Conversion Rate. The conversion rate in effect at any
time for conversion of the Series A Preferred (the "Series A Conversion Rate")
shall be the quotient obtained by dividing the Series A Liquidation Value by the
"Series A Conversion Price" calculated as provided in Section 4.2(e)(iii). The
conversion rate in effect at any time for conversion of the Series B/B-1
Preferred (the "Series B/B-1 Conversion Rate") shall be the quotient obtained by
dividing the Series B/B-1 Liquidation Value by the "Series B/B-1 Conversion
Price" calculated as provided in Section 4.2(e)(iii).

                                       7
<PAGE>   33

               (iii) Conversion Price. The conversion price for the Series A
Preferred (the "Series A Conversion Price") shall initially be the Original
Series A Issue Price (i.e., $3.00). Such initial Series A Conversion Price shall
be adjusted from time to time in accordance with this Section 4.2(e). If and
whenever on or after the first date of issuance of any shares of Series A
Preferred (the "Original Series A Issue Date") the Corporation issues or sells,
or in accordance with this Section 4.2(e)(iii) is deemed to have issued or sold,
any shares of its Common Stock (other than pursuant to a Permitted Issuance) for
a consideration per share less than the Series A Conversion Price in effect
immediately prior to the time of such issue or sale, then immediately upon such
issue or sale or deemed issue or sale the Series A Conversion Price shall be
reduced to the amount determined by dividing (a) the sum of (1) the product
derived by multiplying the Series A Conversion Price in effect immediately prior
to such issue or sale by the number of shares of Common Stock Deemed Outstanding
immediately prior to such issue or sale, plus (2) the consideration, if any,
received or deemed to have been received by the Corporation upon such issue or
sale, by (b) the number of shares of Common Stock Deemed Outstanding immediately
after such issue or sale. All references to the Series A Conversion Price herein
shall mean the Series A Conversion Price as so adjusted.

     The conversion price for the Series B/B-1 Preferred (the "Series B/B-1
Conversion Price") shall initially be the Original Series B/B-1 Issue Price
(i.e., $6.00). Such initial Series B/B-1 Conversion Price shall be adjusted from
time to time in accordance with this Section 4.2(e). Except with respect to
Defaulting Purchasers (as defined in Section 4.2 (e)(ix) below) for whom the
Series B/B-1 Conversion Price shall be as set forth in Section 4.2(e)(ix) below,
if and whenever on or after the first date of issuance of any shares of Series
B/B-1 Preferred (the "Original Series B/B-1 Issue Date") the Corporation issues
or sells, or in accordance with this Section 4.2(e)(iii) is deemed to have
issued or sold, any shares of its Common Stock (other than pursuant to a
Permitted Issuance) for a consideration per share less than the Series B/B-1
Conversion Price in effect immediately prior to the time of such issue or sale,
then immediately upon such issue or sale or deemed issue or sale the Series
B/B-1 Conversion Price shall be reduced to the amount determined by dividing (a)
the sum of (1) the product derived by multiplying the Series B/B-1 Conversion
Price in effect immediately prior to such issue or sale by the number of shares
of Common Stock Deemed Outstanding immediately prior to such issue or sale, plus
(2) the consideration, if any, received or deemed to have been received by the
Corporation upon such issue or sale, by (b) the number of shares of Common Stock
Deemed Outstanding immediately after such issue or sale. All references to the
Series B/B-1 Conversion Price herein shall mean the Series B/B-1 Conversion
Price as adjusted pursuant to this Section 4.2(e)(iii) and Section 4.2 (e)(ix)
below.

     For purposes of determining the adjusted Series A Conversion Price for any
holder of Series Preferred and/or the adjusted Series B/B-1 Conversion Price for
any holder of Series Preferred except for a Defaulting Purchaser, the following
shall be applicable:

                                       8
<PAGE>   34

                    (A) Issuance of Rights or Options. Except for Permitted
Issuances, if the Corporation in any manner grants or sells any Options and the
price per share for which Common Stock is issuable upon the exercise of such
Options, or upon conversion or exchange of any Convertible Securities issuable
upon exercise of such Options, is less than the Series A Conversion Price and/or
the Series B/B-1 Conversion Price, as the case may be, in effect immediately
prior to the time of the granting or sale of such Options, then the total
maximum number of shares of Common Stock issuable upon the exercise of such
Options or upon conversion or exchange of the total maximum amount of such
Convertible Securities issuable upon the exercise of such Options shall be
deemed to have been issued and sold by the Corporation at the time of the
granting or sale of such Options for such price per share. For purposes of this
paragraph, the "price per share for which Common Stock is issuable" shall be
determined by dividing (1) the total amount, if any, received or receivable by
the Corporation as consideration for the granting or sale of such Options, plus
the minimum aggregate amount of additional consideration payable to the
Corporation upon exercise of all such Options, plus in the case of such Options
which relate to Convertible Securities, the minimum aggregate amount of
additional consideration, if any, payable to the Corporation upon the issuance
or sale of such Convertible Securities and the conversion or exchange thereof,
by (2) the total maximum number of shares of Common Stock issuable upon the
exercise of such Options or upon the conversion or exchange of all such
Convertible Securities issuable upon the exercise of such Options. No further
adjustment of the Series A Conversion Price and/or the Series B/B-1 Conversion
Price shall be made when Convertible Securities are actually issued upon the
exercise of such Options or when Common Stock is actually issued upon the
exercise of such Options or the conversion or exchange of such Convertible
Securities.

                    (B) Issuance of Convertible Securities. If the Corporation
in any manner issues or sells any Convertible Securities and the price per share
for which Common Stock is issuable upon conversion or exchange thereof is less
than the Series A Conversion Price and/or the Series B/B-1 Conversion Price, as
the case may be, in effect immediately prior to the time of such issue or sale,
then the maximum number of shares of Common Stock issuable upon conversion or
exchange of such Convertible Securities shall be deemed to have been issued and
sold by the Corporation at the time of the issuance or sale of such Convertible
Securities for such price per share. For the purposes of this paragraph, the
"price per share for which Common Stock is issuable" shall be determined by
dividing (1) the total amount received or receivable by the Corporation as
consideration for the issue or sale of such Convertible Securities, plus the
minimum aggregate amount of additional consideration, if any, payable to the
Corporation upon the conversion or exchange thereof, by (2) the total maximum
number of shares of Common Stock issuable upon the conversion or exchange of all
such Convertible Securities. No further adjustment of the Series A Conversion
Price and/or the Series B/B-1 Conversion Price, as the case may be, shall be
made when Common Stock is actually issued upon the conversion or exchange of
such Convertible Securities, and if any such issue or sale of such Convertible
Securities is made upon exercise of any Options for which adjustments of the
Series A Conversion Price and/or

                                       9
<PAGE>   35

the Series B/B-1 Conversion Price had been or are to be made pursuant to other
provisions of this Section 4.2(e), no further adjustment of the Series A
Conversion Price and/or the Series B/B-1 Conversion Price shall be made by
reason of such issue or sale.

                    (C) Change in Option Price or Conversion Rate. If the
purchase price provided for in any Options, the additional consideration, if
any, payable upon the conversion or exchange of any Convertible Securities or
the rate at which any Convertible Securities are convertible into or
exchangeable for Common Stock changes at any time, the Series A Conversion Price
and/or the Series B/B-1 Conversion Price, as the case may be, in effect at the
time of such change shall be immediately adjusted to the Series A Conversion
Price and/or the Series B/B-1 Conversion Price which would have been in effect
at such time had such Options or Convertible Securities still outstanding
provided for such changed purchase price, additional consideration or conversion
rate, as the case may be, at the time initially granted, issued or sold.

                    (D) Treatment of Expired Options and Unexercised Convertible
Securities. Upon the expiration of any Option or the termination of any right to
convert or exchange any Convertible Security without the exercise of any such
Option or right, the Series A Conversion Price and/or the Series B/B-1
Conversion Price then in effect hereunder shall be adjusted immediately to the
Series A Conversion Price and/or the Series B/B-1 Conversion Price which would
have been in effect at the time of such expiration or termination had such
Option or Convertible Security, to the extent outstanding immediately prior to
such expiration or termination, never been issued.

                    (E) Calculation of Consideration Received. If any Common
Stock, Option or Convertible Security is issued or sold or deemed to have been
issued or sold for cash, the consideration received therefor shall be deemed to
be the amount received by the Corporation therefor (net of discounts,
commissions and related expenses). If any Common Stock, Option or Convertible
Security is issued or sold for a consideration other than cash, the amount of
the consideration other than cash received by the Corporation shall be the fair
value of such consideration. If any Common Stock, Option or Convertible Security
is issued to the owners of the non-surviving entity in connection with any
merger in which the Corporation is the surviving corporation, the amount of
consideration therefor shall be deemed to be the fair value of such portion of
the net assets and business of the non-surviving entity as is attributable to
such Common Stock, Option or Convertible Security, as the case may be. The fair
value of any consideration other than cash and securities shall be determined
jointly by the Corporation and the Required Holders. If such parties are unable
to reach agreement within a reasonable period of time, the fair value of such
consideration shall be determined by an independent appraiser experienced in
valuing such type of consideration jointly selected by the Corporation and the
Required Holders. The determination of such appraiser shall be final and binding
upon the parties, and the fees and expenses of such appraiser shall be borne by
the Corporation.

                    (F) Integrated Transactions. In case any Option is issued in
connection with the issue or sale of other securities of the Corporation,
together

                                       10
<PAGE>   36

comprising one integrated transaction in which no specific consideration is
allocated to such Option by the parties thereto, the Option shall be deemed to
have been issued for a consideration of $.01.

                    (G) Treasury Shares. The number of shares of Common Stock
outstanding at any given time shall not include shares owned or held by or for
the account of the Corporation or any Subsidiary, and the disposition of any
shares so owned or held shall be considered an issue or sale of Common Stock.

               (iv) Adjustment for Stock Splits and Combinations. If the
Corporation shall at any time or from time to time effect a subdivision of the
outstanding Common Stock, the Series A Conversion Price and the Series B/B-1
Conversion Price in effect immediately before that subdivision shall be
proportionately decreased. Conversely, if the Corporation shall at any time or
from time to time combine the outstanding shares of Common Stock into a smaller
number of shares, the Series A Conversion Price and the Series B/B-1 Conversion
Price in effect immediately before the combination shall be proportionately
increased. Any adjustment under this Section 4.2(e)(iv) shall become effective
at the close of business on the date the subdivision or combination becomes
effective.

               (v) Adjustment for Common Stock Dividends and Distributions. If
the Corporation at any time or from time to time makes, or fixes a record date
for the determination of holders of Common Stock entitled to receive, a divided
or other distribution payable in additional shares of Common Stock, in each such
event the Series A Conversion Price and the Series B/B-1 Conversion Price that
is then in effect shall be decreased as of the time of such issuance or, in the
event such record date is fixed, as of the close of business on such record
date, by multiplying each of the Series A Conversion Price and the Series B/B-1
Conversion Price then in effect by a fraction (1) the numerator of which is the
total number of shares of Common Stock issued and outstanding immediately prior
to the time of such issuance or the close of business on such record date, and
(2) the denominator of which is the total number of shares of Common Stock
issued and outstanding immediately prior to the time of such issuance or the
close of business on such record date plus the number of shares of Common Stock
issuable in payment of such dividend or distribution; provided, however, that if
such record date is fixed and such dividend is not fully paid or if such
distribution is not fully made on the date fixed therefor, the Series A
Conversion Price and the Series B/B-1 Conversion Price shall be recomputed
accordingly as of the close of business on such record date and thereafter the
Series A Conversion Price and the Series B/B-1 Conversion Price shall be
adjusted pursuant to this Section 4.2(e)(v) to reflect the actual payment of
such dividend or distribution.

               (vi) Adjustments for Other Dividends and Distributions. If the
Corporation at any time or from time to time makes, or fixes a record date for
the determination of holders of Common Stock entitled to receive, a dividend or
other distribution payable in securities of the Corporation other than shares of
Common Stock, in each such event provision shall be made so that the holders of
the Series Preferred

                                       11
<PAGE>   37

shall receive upon conversion thereof, in addition to the number of shares of
Common Stock receivable thereupon, the amount of other securities of the
Corporation which they would have received had their Series Preferred been
converted into Common Stock on the date of such event and had they thereafter,
during the period from the date of such event to and including the conversion
date, retained such securities receivable by them as aforesaid during such
period, subject to all other adjustments called for during such period under
this Section 4.2(e) with respect to the rights of the holders of the Series
Preferred or with respect to such other securities by their terms.

               (vii) Adjustment for Reclassification, Exchange and Substitution.
If at any time or from time to time the Common Stock issuable upon the
conversion of the Series Preferred is changed into the same or a different
number of shares of any class or classes of stock, whether by recapitalization,
reclassification or otherwise (other than a subdivision or combination of shares
or stock dividend or a reorganization, merger, consolidation or sale of assets
provided for elsewhere in this Section 4.2), in any such event each holder of
the Series Preferred shall have the right thereafter to convert such stock into
the kind and amount of stock and other securities and property receivable in
connection with such recapitalization, reclassification or other change by
holders of the maximum number of shares of Common Stock into which such shares
of the Series Preferred could have been converted immediately prior to such
recapitalization, reclassification or change, all subject to further adjustments
as provided herein or with respect to such other securities or property by the
terms thereof.

               (viii) Reorganizations, Mergers, Consolidations or Sales of
Assets. If at any time or from time to time there is a capital reorganization of
the Common Stock (other than a recapitalization, subdivision, combination,
reclassification, exchange or substitution of shares provided for elsewhere in
this Section 4.2), as a part of such capital reorganization, provision shall be
made so that the holders of the Series Preferred shall thereafter be entitled to
receive upon conversion of the Series Preferred the number of shares of stock or
other securities or property of the Corporation to which a holder of the maximum
number of shares of Common Stock deliverable upon conversion would have been
entitled in connection with such capital reorganization, subject to adjustment
in respect of such stock or securities by the terms thereof. In any such case,
appropriate adjustment shall be made in the application of the provisions of
this Section 4.2(e) with respect to the rights of the holders of the Series
Preferred after the capital reorganization to the end that the provisions of
this Section 4.2 (including adjustment of the Series A Conversion Price and the
Series B/B-1 Conversion Price then in effect and the number of shares of Common
Stock issuable upon conversion of the Series Preferred) shall be applicable
after that event and be as nearly equivalent as practicable.

               (ix) Adjustment upon Default under Stock Purchase Agreements.
With respect to the shares of Series B/B-1 Preferred owned by a Defaulting
Purchaser who has not Cured such Default within a 10-day cure period, (as such
terms are defined in Amendment No. 1 to Series B Preferred Stock Purchase
Agreement dated as of December 31, 1999, and in Article 3 of the Follow-On
Series B/B-1 Preferred

                                       12
<PAGE>   38

Stock Purchase Agreement dated December 20, 1999, in each case among the
Corporation and certain purchasers of the Corporation's Series B/B-1 Preferred
(collectively, the "Stock Purchase Agreements")), immediately upon the
expiration of such 10-day cure period, the Series B/B-1 Conversion Price for
such shares in effect immediately prior to such Default shall be increased to an
amount equal to two (2) times the Original Series B/B-1 Issue Price. Once the
Series B/B-1 Conversion Price for such shares of Series B/B-1 Preferred held by
the Defaulting Purchaser is adjusted in accordance with this Section 4.2(e)(ix),
it shall no longer be subject to any other adjustment provided in Section
4.2(e)(iii) of this Certificate of Incorporation. This Section 4.2(e)(ix) shall
not affect the Series B/B-1 Conversion Price for any holder of Series B/B-1
Preferred other than the Defaulting Purchaser, shall not affect the Series A
Conversion Price for shares of Series A Preferred held by the Defaulting
Purchaser, and shall not affect the Series B/B-1 Liquidation Value for any
holder of Series B/B-1 Preferred.

               (x) Certificate of Adjustment. In each case of an adjustment or
readjustment of the Series A Conversion Price and/or the Series B/B-1 Conversion
Price for the number of shares of Common Stock or other securities issuable upon
conversion of the Series Preferred, the Corporation, at its expense, shall
compute such adjustment or readjustment in accordance with the provisions hereof
and prepare a certificate showing such adjustment or readjustment, and shall
mail such certificate, by first class mail, postage prepaid, to each registered
holder of the Series Preferred at the holder's address as shown in the
Corporation's books. The certificate shall set forth such adjustment or
readjustment, showing in detail the facts upon which such adjustment or
readjustment is based, including a statement of (1) the consideration received
or deemed to be received by the Corporation for any additional shares of Common
Stock issued or sold or deemed to have been issued or sold, (2) the Series A
Conversion Price and/or the Series B/B-1 Conversion Price at the time in effect,
(3) the number of additional shares of Common Stock issued or sold or deemed to
have been issued or sold, and (4) the type and amount, if any, of other property
which at the time would be received upon conversion of the Series Preferred.

               (xi) Notices of Record Date. Upon (i) any taking by the
Corporation of a record of the holders of any class of securities for the
purpose of determining the holders thereof who are entitled to receive any
dividend or other distribution, or (ii) any Acquisition (as defined in Section
4.2(c)(iii)(A)) or other capital reorganization of the Corporation, any
reclassification or recapitalization of the capital stock of the Corporation,
any merger or consolidation of the Corporation with or into any other
corporation, any Asset Transfer (as defined in Section 4.2(c)(iii)(B)), or any
voluntary or involuntary dissolution, liquidation or winding up of the
Corporation, the Corporation shall mail to each holder of the Series Preferred
at least twenty (20) days prior to the record date specified therein a notice
specifying (1) the date on which any such record is to be taken for the purpose
of such dividend or distribution and a description of such dividend or
distribution, (2) the date on which any such Acquisition, reorganization,
reclassification, transfer, consolidation, merger, Asset Transfer, dissolution,
liquidation or winding up is expected to become effective, and (3) the date,

                                       13
<PAGE>   39

if any, that is to be fixed for determining the holders of record of Common
Stock (or other securities) that shall be entitled to exchange their shares of
Common Stock (or other securities) for securities or other property deliverable
upon such Acquisition, reorganization, reclassification, transfer,
consolidation, merger, Asset Transfer, dissolution, liquidation or winding up.

               (xii) Automatic Conversion into Common Stock. Each share of the
Series Preferred shall automatically be converted into shares of Common Stock
(Voting Common Stock in the case of Series A Preferred and Series B Preferred,
and Non-Voting Common Stock in the case of Series B-1 Preferred), based on the
then-effective Series A Conversion Price and/or the Series B/B-1 Conversion
Price, as the case may be, immediately upon the closing of a firmly underwritten
public offering pursuant to an effective registration statement under the
Securities Act of 1933, as amended, covering the offer and sale of Common Stock
for the account of the Corporation in which (i) the per share price to the
public is at least $15.00 per share (as adjusted for stock splits,
recapitalizations and the like), and (ii) the gross cash proceeds to the
Corporation (prior to expenses and underwriting commissions) are at least
$50,000,000. Upon such automatic conversion, all declared but unpaid dividends,
if any, shall be paid in accordance with Section 4.2(a).

               (xiii) Mechanics of Conversion.

                    (A) Optional Conversion. Each holder of the Series Preferred
who desires to convert the same into shares of Common Stock pursuant to this
Section 4.2(e) shall surrender the certificate or certificates therefor, duly
endorsed, at the office of the Corporation or any transfer agent for the Series
Preferred, and shall give written notice to the Corporation at such office that
such holder elects to convert the same. Such notice shall state the number of
shares of the Series Preferred being converted. Thereupon, the Corporation shall
promptly issue and deliver at such office to such holder a certificate or
certificates for the number of shares of Common Stock to which such holder is
entitled and shall promptly pay in cash or, to the extent sufficient funds are
not then legally available therefor, in Common Stock (at the Common Stock's fair
market value determined by the Corporation's board of directors as of the date
of such conversion), any declared but unpaid dividends on the shares of the
Series Preferred being converted. Such conversion shall be deemed to have been
made at the close of business on the date of such surrender of the certificate
representing the shares of the Series Preferred to be converted, and the person
entitled to receive the shares of Common Stock issuable upon such conversion
shall be treated for all purposes as the record holder of such shares of Common
Stock on such date.

                    (B) Automatic Conversion. Upon the occurrence of the event
specified in Section 4.2(e)(xii) above, the outstanding shares of the Series
Preferred shall be converted into Common Stock (Voting Common Stock in the case
of Series A Preferred and Series B Preferred, and Non-Voting Common Stock in the
case of Series B-1 Preferred) automatically without any further action by the
holders of such shares and whether or not the certificates representing such
shares are surrendered to the

                                       14
<PAGE>   40

Corporation or its transfer agent; provided, however, that the Corporation shall
not be obligated to issue certificates evidencing the shares of Common Stock
issuable upon such conversion unless the certificates evidencing such shares of
the Series Preferred are either delivered to the Corporation or its transfer
agent as provided below, or the holder notifies the Corporation or its transfer
agent that such certificates have been lost, stolen or destroyed and executes an
agreement satisfactory to the Corporation to indemnify the Corporation from any
loss incurred by it in connection with such certificates. Upon surrender by any
holder of the certificates formerly representing shares of the Series Preferred
at the office of the Corporation or any transfer agent for the Series Preferred,
there shall be issued and delivered to such holder promptly at such office and
in its name as shown on such surrendered certificate or certificates, a
certificate or certificates for the number of shares of Common Stock into which
the shares of the Series Preferred surrendered were convertible on the date on
which such automatic conversion occurred, and the Corporation shall promptly pay
in cash or, at the option of the Corporation, Common Stock (at the Common
Stock's fair market value determined by the Corporation's board of directors as
of the date of such conversion) or, at the option of the Corporation, a
combination of both, all declared but unpaid dividends on the shares of the
Series Preferred being converted. Until surrendered as provided above, each
certificate formerly representing shares of the Series Preferred shall be deemed
for all corporate purposes to represent the number of shares of Common Stock
resulting from such automatic conversion.

               (xiv) Fractional Shares. No fractional shares of Common Stock
shall be issued upon conversion of the Series Preferred. All shares of Common
Stock (including fractions thereof) issuable upon conversion of more than one
share of the Series Preferred by a holder thereof shall be aggregated for
purposes of determination whether the conversion would result in the issuance of
any fractional share. If, after the aforementioned aggregation, the conversion
would result in the issuance of any fractional share, the Corporation shall, in
lieu of issuing any fractional share, pay cash equal to the product of such
fraction multiplied by the Common Stock's fair market value (as determined by
the Corporation's board of directors) on the date of conversion.

          (f) CONVERSION RIGHTS - CONVERSION OF SERIES B PREFERRED INTO SERIES
B-1 PREFERRED OR VICE-VERSA.

     The holders of Series B/B-1 Preferred shall have the following rights with
respect to the conversion of Series B Preferred into Series B-1 Preferred or
vice-versa:

               (i) Conversion of Series B Preferred into Series B-1 Preferred.
At any Regulated Holder's request at any time (whether in connection with any
action by the Corporation referred to in Section 4.2(f)(ii)(B) or otherwise),
such Regulated Holder shall have the right, upon the occurrence or possible
occurrence of a Regulatory Problem, to convert any number of shares of Series B
Preferred then held by such Regulated Holder into an equal number of shares of
Series B-1 Preferred.

               (ii) Conversion of Series B-1 Preferred into Series B Preferred.

                                       15
<PAGE>   41

                    (A) In connection with the occurrence (or the expected
occurrence as described in Section 4.2(f)(ii)(C) below) of any Conversion Event,
each holder of Series B-1 Preferred shall be entitled to convert into an equal
number of Series B Preferred all of such holder's Series B-1 Preferred being (or
expected to be) distributed, disposed of or sold in connection with such
Conversion Event.

                    (B) A "Conversion Event" shall mean (i) any public offering
or public sale of securities of the Corporation (including a public offering
registered under the Securities Act and a public sale pursuant to Rule 144 of
the Securities Exchange Commission or any similar rule then in force), (ii) any
sale of securities of the Corporation to a person or group of persons (within
the meaning of the U.S. Securities Exchange Act of 1934, as amended (the "1934
Act")) if, after such sale, such person or group of persons in the aggregate
would own or control securities which possess in the aggregate the ordinary
power to elect a majority of the Corporation's board of directors (provided that
such sale has been approved by the Corporation's board of directors or a
committee thereof), (iii) any sale of securities of the Corporation to a person
or group of persons (within the meaning of the 1934 Act) if, after such sale,
such person or group of persons in the aggregate would own or control securities
of the Corporation (excluding any Series B-1 Preferred being converted and
disposed of in connection with such Conversion Event) which possesses in the
aggregate the ordinary power to elect a majority of the Corporation's board of
directors, (iv) any sale of securities of the Corporation to a person or group
of persons (within the meaning of the 1934 Act) if, after such sale, such person
or group of persons would not, in the aggregate, own, control or have the right
to acquire more than two percent (2%) of the outstanding securities of any class
of voting securities of the Corporation, and (v) a merger, consolidation or
similar transaction involving the Corporation if, after such transaction, a
person or group of persons (within the meaning of the 1934 Act) in the aggregate
would own or control securities which possess in the aggregate the ordinary
voting power to elect a majority of the surviving company's directors (provided
that the transaction has been approved by the Corporation's board of directors
or a committee thereof).

                    (C) Each Regulated Holder holding Series B-1 Preferred shall
be entitled to convert Series B-1 Preferred in connection with any Conversion
Event if such Regulated Holder reasonably believes that such Conversion Event
shall be consummated, and a written request for conversion from any Regulated
Holder holding Series B-1 Preferred to the Corporation shall obligate the
Corporation to effect such conversion in a timely manner so as to enable each
such Regulated Holder to participate in such Conversion Event. The Corporation
shall not cancel the Series B-1 Preferred so converted before the tenth day
following such Conversion Event and shall reserve such Series B-1 Preferred
until such tenth day for reissuance in compliance with the next sentence. If any
Series B-1 Preferred are converted into Series B Preferred in connection with a
Conversion Event and such Series B Preferred are not actually distributed,
disposed of or sold pursuant to such Conversion Event, such Series B Preferred
shall be promptly converted back into the same number of Series B-1 Preferred.

                                       16
<PAGE>   42

                    (D) If at any time the Bank Holding Company Act and the
rules and regulations thereunder (the "BHCA Rules") are amended to allow a
holder of Series B-1 Preferred to convert to Series B Preferred, then upon any
Regulated Holder's request, such Regulated Holder shall have the right to
convert shares of Series B-1 Preferred into an equal number of shares of Series
B Preferred to the extent permissible at such time under the BHCA Rules (as
determined by such holder in its sole discretion).

               (iii) Conversion Procedure.

                    (A) Unless otherwise provided in connection with any
conversion, each conversion of Series B-1 Preferred or Series B Preferred, into
Series B Preferred or Series B-1 Preferred, as the case may be, shall be
effected by the surrender of the certificate or certificates representing the
shares to be converted at the principal office of the Corporation at any time
during normal business hours, together with a written notice by the holder of
such shares stating that such holder desires to convert the shares, or a stated
number of the shares, represented by such certificate or certificates into
shares of the other class (and such statement shall obligate the Corporation to
issue such shares). Unless otherwise provided in connection with any conversion,
each conversion shall be deemed to have been effected as of the close of
business on the date on which such certificate or certificates have been
surrendered and such notice has been received, and at such time the rights of
the holder of the converted Series B-1 Preferred and Series B Preferred, as the
case may be, as such holder shall cease and the person or persons in whose name
or names the certificate or certificates for shares of Series B Preferred or
Series B-1 Preferred are to be issued upon such conversion shall be deemed to
have become the holder or holders of record of the Series B Preferred and the
Series B-1 Preferred represented thereby.

                    (B) Promptly after the surrender of certificates and the
receipt of written notice, the Corporation shall issue and deliver in accordance
with the surrendering holder's instructions (i) the certificate or certificates
for the Series B Preferred and the Series B-1 Preferred issuable upon such
conversion and (ii) a certificate representing any Series B-1 Preferred and
Series B Preferred which were represented by the certificate or certificates
delivered to the Corporation in connection with such conversion but which were
not converted.

                    (C) The issuance of certificates for Series B-1 Preferred or
Series B Preferred upon conversion of Series B Preferred or Series B-1
Preferred, respectively, shall be made without charge to the holders of such
shares for any issuance tax in respect thereof or other cost incurred by the
Corporation in connection with such conversion and the related issuance of
Series B Preferred and Series B-1 Preferred, as the case may be.

                    (D) The Corporation has duly authorized, solely for the
purpose of issuance upon the conversion of the Series B-1 Preferred and Series B
Preferred, respectively, such number of Series B Preferred and Series B-1
Preferred, as

                                       17
<PAGE>   43

the case may be issuable upon the conversion of all outstanding Series B-1
Preferred and Series B Preferred, as the case may be. All shares which are so
issuable shall, when issued, be duly and validly issued, fully paid and
nonassessable and free from all taxes, liens and charges. The Corporation shall
take all such actions as may be necessary to ensure that all such shares may be
so issued without violation of any applicable law or governmental regulation or
any requirements of any domestic securities exchange upon which shares may be
listed (except for official notice of issuance which shall be immediately
transmitted by the Corporation upon issuance).

                    (E) The Corporation shall not close its books against the
transfer of Series B-1 Preferred and Series B Preferred in any manner which
would interfere with the timely conversion of any Series B-1 Preferred or Series
B Preferred. The Corporation shall assist and cooperate with any holder of
Series B-1 Preferred and Series B Preferred required to make any governmental
filings or obtain any governmental approval prior to or in connection with any
conversion of Series B-1 Preferred and Series B Preferred hereunder (including,
without limitation, making any filings required to be made by the Corporation).

                    (F) If the Corporation in any manner subdivides or combines
the outstanding Series B-1 Preferred or Series B Preferred, the outstanding
shares of the other class shall be proportionately subdivided or combined in a
similar manner.

          (g) CONVERSION RIGHTS - CONVERSION OF NON-VOTING COMMON STOCK INTO
VOTING COMMON STOCK AND VICE-VERSA.

     The holders of Common Stock shall have the following rights with respect to
the conversion of Voting Common Stock into Non-Voting Common Stock or
vice-versa:

               (i) Conversion of Voting Common Stock into Non-Voting Common
Stock. At any Regulated Holder's request at any time (whether in connection with
any action by the Corporation referred to in Section 4.2(f)(ii)(B) above or
otherwise), such Regulated Holder shall have the right, upon the occurrence or
possible occurrence of a Regulatory Problem, to convert any number of shares of
Voting Common Stock then held by such Regulated Holder into an equal number of
shares of Non-Voting Common Stock.

               (ii) Conversion of Non-Voting Common Stock into Voting Common
Stock.

                    (A) In connection with the occurrence (or the expected
occurrence as described in Section 4.2(g)(ii)(B) below) of any Conversion Event,
each holder of Non-Voting Common Stock shall be entitled to convert into an
equal number of Voting Common Stock all of such holder's Non-Voting Common Stock
being (or expected to be) distributed, disposed of or sold in connection with
such Conversion Event.

                                       18
<PAGE>   44

                    (B) Each Regulated Holder holding Non-Voting Common Stock
shall be entitled to convert Non-Voting Common Stock in connection with any
Conversion Event if such Regulated Holder reasonably believes that such
Conversion Event shall be consummated, and a written request for conversion from
any Regulated Holder holding Non-Voting Common Stock to the Corporation shall
obligate the Corporation to effect such conversion in a timely manner so as to
enable each such Regulated Holder to participate in such Conversion Event. The
Corporation shall not cancel the Non-Voting Common Stock so converted before the
tenth day following such Conversion Event and shall reserve such Non-Voting
Common Stock until such tenth day for reissuance in compliance with the next
sentence. If any Non-Voting Common Stock are converted into Voting Common Stock
in connection with a Conversion Event and such Voting Common Stock are not
actually distributed, disposed of or sold pursuant to such Conversion Event,
such Voting Common Stock shall be promptly converted back into the same number
of Non-Voting Common Stock.

                    (C) If at any time the BHCA Rules are amended to allow a
holder of Non-Voting Common Stock to convert to Voting Common Stock, then upon
any Regulated Holder's request, such Regulated Holder shall have the right to
convert shares of Non-Voting Common Stock into an equal number of shares of
Voting Common Stock to the extent permissible at such time under the BHCA Rules
(as determined by such holder in its sole discretion).

               (iii) Conversion Procedure.

                    (A) Unless otherwise provided in connection with any
conversion, each conversion of Non-Voting Common Stock or Voting Common Stock,
into Voting Common Stock or Non-Voting Common Stock, as the case may be, shall
be effected by the surrender of the certificate or certificates representing the
shares to be converted at the principal office of the Corporation at any time
during normal business hours, together with a written notice by the holder of
such shares stating that such holder desires to convert the shares, or a stated
number of the shares, represented by such certificate or certificates into
shares of the other class (and such statement shall obligate the Corporation to
issue such shares). Unless otherwise provided in connection with any conversion,
each conversion shall be deemed to have been effected as of the close of
business on the date on which such certificate or certificates have been
surrendered and such notice has been received, and at such time the rights of
the holder of the converted Non-Voting Common Stock and Voting Common Stock, as
the case may be, as such holder shall cease and the person or persons in whose
name or names the certificate or certificates for shares of Voting Common Stock
or Non-Voting Common Stock are to be issued upon such conversion shall be deemed
to have become the holder or holders of record of the Voting Common Stock and
the Non-Voting Common Stock represented thereby.

                    (B) Promptly after the surrender of certificates and the
receipt of written notice, the Corporation shall issue and deliver in accordance
with the surrendering holder's instructions (i) the certificate or certificates
for the Voting

                                       19
<PAGE>   45

Common Stock and the Non-Voting Common Stock issuable upon such conversion and
(ii) a certificate representing any Non-Voting Common Stock and Voting Common
Stock which were represented by the certificate or certificates delivered to the
Corporation in connection with such conversion but which were not converted.

                    (C) The issuance of certificates for Non-Voting Common Stock
or Voting Common Stock upon conversion of Voting Common Stock or Non-Voting
Common Stock, respectively, shall be made without charge to the holders of such
shares for any issuance tax in respect thereof or other cost incurred by the
Corporation in connection with such conversion and the related issuance of
Voting Common Stock and Non-Voting Common Stock, as the case may be.

                    (D) The Corporation has duly authorized, solely for the
purpose of issuance upon the conversion of the Non-Voting Common Stock and
Voting Common Stock, respectively, such number of Voting Common Stock and
Non-Voting Common Stock, as the case may be issuable upon the conversion of all
outstanding Non-Voting Common Stock and Voting Common Stock, as the case may be.
All shares which are so issuable shall, when issued, be duly and validly issued,
fully paid and nonassessable and free from all taxes, liens and charges. The
Corporation shall take all such actions as may be necessary to ensure that all
such shares may be so issued without violation of any applicable law or
governmental regulation or any requirements of any domestic securities exchange
upon which shares may be listed (except for official notice of issuance which
shall be immediately transmitted by the Corporation upon issuance).

                    (E) The Corporation shall not close its books against the
transfer of Non-Voting Common Stock and Voting Common Stock in any manner which
would interfere with the timely conversion of any Non-Voting Common Stock or
Voting Common Stock. The Corporation shall assist and cooperate with any holder
of Non-Voting Common Stock and Voting Common Stock required to make any
governmental filings or obtain any governmental approval prior to or in
connection with any conversion of Non-Voting Common Stock and Voting Common
Stock hereunder (including, without limitation, making any filings required to
be made by the Corporation).

                    (F) If the Corporation in any manner subdivides or combines
the outstanding Non-Voting Common Stock or Voting Common Stock, the outstanding
shares of the other class shall be proportionately subdivided or combined in a
similar manner.

any certificate evidencing shares of the Series Preferred, and in the case of
any such loss, theft or destruction, upon receipt of indemnity reasonably
satisfactory to the Corporation (provided, however, that if the holder is a
financial institution or other institutional investor its own agreement shall be
satisfactory), or in the case of any such mutilation upon surrender of such
certificate, the Corporation shall (at its expense) execute and deliver in lieu
of such certificate a new certificate of like kind representing the number of
shares of such class represented by such lost, stolen, destroyed or mutilated
certificate and dated the date of such lost, stolen, destroyed or mutilated
certificate.

but unissued shares of Common Stock, solely for the purpose of effecting the
conversion of the shares of the Series Preferred, such number of its shares of
Common Stock as shall from time to time be sufficient to effect the conversion
of all outstanding shares of the Series Preferred. If at any time the number of
authorized but unissued shares of Common Stock shall not be sufficient to effect
the conversion of all then-outstanding shares of the Series Preferred, the
Corporation shall take such corporate action as may, in the opinion of its
counsel, be necessary to increase its authorized but unissued shares of Common
Stock to such number of shares as shall be sufficient for such purpose.

2. EXERCISE OF WARRANT

         2.1. Payment. Subject to compliance with the terms and conditions of
this Warrant and applicable securities laws and subject to the vesting
conditions referenced in Section 2.8, this Warrant may be exercised, in whole or
in part at any time or from time to time, on or before the Expiration Date by
the delivery (including, without limitation, delivery by facsimile) of the form
of Notice of Exercise attached hereto as Exhibit 1 (the "Notice of Exercise"),
duly executed by the Holder, at the principal office of the Company, and as soon
as practicable after such date, surrendering

              (a) this Warrant at the principal office of the Company, and

              (b) payment, in cash (by check) or by wire transfer, of an amount
equal to the product obtained by multiplying the number of shares of Common
Stock being purchased upon such exercise by the then effective Purchase Price
(the "Exercise Amount"), except that if Holder is subject to HSR Act
Restrictions (as defined in Section 2.6 below), the Exercise Amount shall be
paid to the Company within five (5) business days of the termination of all HSR
Act Restrictions.

         2.2. Net Issue Exercise. In lieu of the payment methods set forth in
Section 2.1(b) above, the Holder may elect to pay the Exercise Amount by
surrendering shares of Common Stock having an aggregate fair market value on the
date of exchange equal to the Exercise Amount. If Holder elects to exercise this
Warrant as provided in this Section 2.2, Holder shall tender to the Company the
Warrant for the amount being exercised, along with written notice of Holder's
election to exercise some or all of the Warrant, and the Company shall issue to
Holder the number of shares of Common Stock computed using the following
formula:

                  X = Y (A-B)
                     ---------
                         A

                  Where X = the number of shares of Common Stock to be issued to
                  Holder.

                                      -2-
<PAGE>   54

                                                      INTEL/VELOCOM CONFIDENTIAL

                  Y = the number of shares of Common Stock purchasable under the
                  Warrant or, if only a portion of the Warrant is being
                  exercised, the portion of the Warrant being canceled (as
                  adjusted to the date of such calculation).

                  A = the Fair Market Value of one share of the Company's Common
                  Stock.

                  B = Purchase Price (as adjusted to the date of such
                  calculation).

         2.3. Initial Public Offering. Upon receipt of a written notice of the
Company's intention to raise capital by selling shares of Common Stock in an IPO
(the "IPO Notice"), which notice shall be delivered to Holder at least thirty
(30) but not more than ninety (90) days before the anticipated date of the
filing with the Securities and Exchange Commission of the registration statement
associated with the IPO, the Holder shall notify the Company within 15 days
after receiving the IPO Notice whether or not the Holder will exercise this
Warrant pursuant to Section 2.2 prior to consummation of the IPO. If the Holder
notifies the Company that it does not intend to exercise this Warrant before
consummation of the IPO or if the Holder does not give timely notice in response
to the IPO Notice, then the Holder will not be allowed to exercise this Warrant
until after consummation of the IPO and completion of the distribution of the
IPO shares or, if sooner, abandonment of the IPO by the Company. Notwithstanding
whether or not an IPO Notice has been delivered to Holder or any other provision
of this Warrant to the contrary, if Holder decides to exercise this Warrant
while a registration statement is on file with the Securities and Exchange
Commission (the "SEC") in connection with the IPO, this Warrant shall be deemed
exercised immediately prior to the consummation of the IPO and the Fair Market
Value of a share of Common Stock will be the "Price to Public" stated in the
final prospectus used for the IPO. If Holder has elected to exercise this
Warrant pursuant to Section 2.2 while a registration statement is on file with
the Securities and Exchange Commission in connection with an IPO and the IPO is
not consummated, then Holder's exercise of this Warrant shall not be effective
unless Holder confirms in writing Holder's intention to go forward with the
exercise of this Warrant.

         2.4. "Easy Sale" Exercise. In lieu of the payment methods set forth in
Section 2.1(b) above, when permitted by law and applicable regulations
(including Nasdaq and NASD rules), the Holder may pay the Purchase Price through
a "same day sale" commitment from the Holder (and if applicable a broker-dealer
that is a member of the National Association of Securities Dealers (a "NASD
Dealer")), whereby the Holder irrevocably elects to exercise this Warrant and to
sell a portion of the Common Stock so purchased to pay for the Purchase Price
and the Holder (or, if applicable, the NASD Dealer) commits upon sale (or, in
the case of the NASD Dealer, upon receipt) of such Common Stock to forward the
Purchase Price directly to the Company.

         2.5. Stock Certificates; Fractional Shares. As soon as practicable on
or after such date, the Company shall issue and deliver to the person or persons
entitled to receive the same a certificate or certificates for the number of
whole shares of Common Stock issuable upon such exercise, together with cash in
lieu of any fraction of a share equal to such fraction of the current Fair
Market Value of one whole share of Common Stock as of the date of exercise of
this Warrant. No fractional shares or scrip representing fractional shares shall
be issued upon an exercise of this Warrant.

         2.6. HSR Act. The Company hereby acknowledges that exercise of this
Warrant by Holder may subject the Company and/or the Holder to the filing
requirements of the HSR Act and that Holder may be prevented from exercising
this Warrant until the expiration or early termination of all waiting periods
imposed by the HSR Act ("HSR Act Restrictions"). If on or before the Expiration
Date Holder has sent the Notice of Exercise to Company and Holder has not been
able to complete the exercise of this Warrant prior to the Expiration Date
because of HSR Act Restrictions, the Holder shall be entitled to complete the
process of exercising this Warrant in accordance with the procedures contained
herein notwithstanding the fact that completion of the exercise of this Warrant
would take place after the Expiration Date or the completion of the IPO.

         2.7. Partial Exercise; Effective Date of Exercise. Any partial exercise
of this Warrant must be for a minimum of 50,000 shares of Common Stock. In case
of any partial exercise of this Warrant, the Company shall cancel this Warrant
upon surrender hereof and shall execute and deliver a new Warrant of like tenor
and date for the balance of the shares of Common Stock purchasable hereunder.
This Warrant shall be deemed to have been exercised immediately prior to the
close of business on the date of its surrender for exercise as provided above.
However, if Holder is subject to HSR Act Restrictions this Warrant shall be
deemed to have been exercised on the date immediately following the date of the
expiration of all HSR Act Restrictions. The person entitled to receive the
shares of Common Stock issuable upon exercise of this Warrant shall be treated
for all purposes as the holder of record of such shares as of the close of
business on the date the Holder is deemed to have exercised this Warrant.

         2.8. Vesting. This Warrant may be exercised only to the extent it has
vested in accordance with attached Attachment A and Attachment B.

         2.9 Expiration Date. This Warrant shall expire on the earliest to occur
of the following: (i) February __, 2003 or (ii) the closing of an acquisition of
the Company by another entity by means of a merger, reorganization,
consolidation or otherwise.

3. VALID ISSUANCE: TAXES. All shares of Common Stock issued upon the exercise of
this Warrant (and shares of Common Stock for issuance on conversion of such
Common Stock) shall be validly issued, fully paid and non-assessable, and the
Company shall pay all taxes and other governmental charges that may be imposed
in respect of the issue or delivery thereof. The Company shall not be required
to pay any tax or other charge imposed in connection with any transfer involved
in the issuance of any certificate for shares of Common Stock in any name other
than that of the Registered Holder of this Warrant, which will only be done in
accordance with and will be subject to the provisions of the Investors Agreement
(defined below), and in such case the Company shall not be required to issue or
deliver any stock certificate or security until such tax or other charge has
been paid, or it has been established to the Company's reasonable satisfaction
that no tax or other charge is due.

4. ADJUSTMENT OF PURCHASE PRICE AND NUMBER OF SHARES. In addition to any
adjustment to the Common Stock required by the terms of such Common Stock in the
Company's Certificate of Incorporation, the number of shares of Common Stock
issuable upon exercise of this Warrant (or any shares of stock or other
securities or property receivable or

                                      -4-
<PAGE>   56

                                                      INTEL/VELOCOM CONFIDENTIAL

issuable upon exercise of this Warrant) and the Purchase Price are subject to
adjustment upon occurrence of the following events:

         4.1. Adjustment for Stock Splits, Stock Subdivisions or Combinations of
Shares. The Purchase Price of this Warrant shall be proportionally decreased and
the number of shares of Common Stock issuable upon exercise of this Warrant (or
any shares of stock or other securities at the time issuable upon exercise of
this Warrant) shall be proportionally increased to reflect any stock split or
subdivision of the Company's Common Stock. The Purchase Price of this Warrant
shall be proportionally increased and the number of shares of Common Stock
issuable upon exercise of this Warrant (or any shares of stock or other
securities at the time issuable upon exercise of this Warrant) shall be
proportionally decreased to reflect any combination or reduction of the
Company's Common Stock.

         4.2. Adjustment for Dividends or Distributions of Stock or Other
Securities or Property. In case the Company shall make or issue, or shall fix a
record date for the determination of eligible holders entitled to receive, a
dividend or other distribution with respect to the Common Stock (or any shares
of stock or other securities at the time issuable upon exercise of this Warrant)
payable in (a) securities of the Company or (b) assets (excluding cash dividends
paid or payable solely out of retained earnings), then, in each such case, the
Holder of this Warrant on exercise hereof at any time after the consummation,
effective date or record date of such dividend or other distribution, shall
receive, in addition to the shares of Common Stock (or such other stock or
securities) issuable on such exercise prior to such date, and without the
payment of additional consideration therefor, the securities or such other
assets of the Company to which such Holder would have been entitled upon such
date if such Holder had exercised this Warrant on the date hereof and had
thereafter, during the period from the date hereof to and including the date of
such exercise, retained such shares and/or all other additional stock available
by it as aforesaid during such period giving effect to all adjustments called
for by this Section 4.

         4.3. Reclassification. If the Company, by reclassification of
securities or otherwise, shall change any of the securities as to which purchase
rights under this Warrant exist into the same or a different number of
securities of any other class or classes, this Warrant shall thereafter
represent the right to acquire such number and kind of securities as would have
been issuable as the result of such change with respect to the securities that
were subject to the purchase rights under this Warrant immediately prior to such
reclassification or other change and the Purchase Price therefore shall be
appropriately adjusted, all subject to further adjustment as provided in this
Section 4. No adjustment shall be made pursuant to this Section 4.3 upon any
conversion or redemption of the Common Stock which is the subject of Section
4.5.

         4.4. Adjustment for Capital Reorganization. In case of any capital
reorganization of the capital stock of the Company (other than a combination,
reclassification, exchange or subdivision of shares otherwise provided for
herein), then, as a part of such reorganization, lawful provision shall be made
so that the Holder of this Warrant shall thereafter be entitled to receive upon
exercise of this Warrant, during the period specified herein and upon payment of
the Purchase Price then in effect, the number of shares of stock or other
securities or property of the successor corporation resulting from such
reorganization that a holder of the shares

                                      -5-
<PAGE>   57
                                                      INTEL/VELOCOM CONFIDENTIAL

deliverable upon exercise of this Warrant would have been entitled to receive in
such reorganization if this Warrant had been exercised immediately before such
reorganization, all subject to further adjustment as provided in this Section 4.
The foregoing provisions of this Section 4.4 shall similarly apply to successive
reorganizations and to the stock or securities of any other corporation that are
at the time receivable upon the exercise of this Warrant. If the per-share
consideration payable to the Holder hereof for shares in connection with any
such transaction is in a form other than cash or marketable securities, then the
value of such consideration shall be determined in good faith by the Company's
Board of Directors. In all events, appropriate adjustment (as determined in good
faith by the Company's Board of Directors) shall be made in the application of
the provisions of this Warrant with respect to the rights and interests of the
Holder after the transaction, to the end that the provisions of this Warrant
shall be applicable after that event, as near as reasonably may be, in relation
to any shares or other property deliverable after that event upon exercise of
this Warrant.

         4.5. Conversion of Common Stock. In case all or any portion of the
authorized and outstanding shares of Common Stock of the Company are redeemed or
converted or reclassified into other securities or property pursuant to the
Company's Certificate of Incorporation or otherwise, or the Common Stock
otherwise ceases to exist, then, in such case, the Holder of this Warrant, upon
exercise hereof at any time after the date on which the Common Stock is so
redeemed or converted, reclassified or ceases to exist (the "Termination Date"),
shall receive, in lieu of the number of shares of Common Stock that would have
been issuable upon such exercise immediately prior to the Termination Date, the
securities or property that would have been received if this Warrant had been
exercised in full and the Common Stock received thereupon had been
simultaneously converted immediately prior to the Termination Date, all subject
to further adjustment as provided in this Warrant.

5. CERTIFICATE AS TO ADJUSTMENTS. In each case of any adjustment in the Purchase
Price, or number or type of shares issuable upon exercise of this Warrant, the
Chief Financial Officer or Controller of the Company shall compute such
adjustment in accordance with the terms of this Warrant and prepare a
certificate setting forth such adjustment and showing in detail the facts upon
which such adjustment is based, including a statement of the adjusted Purchase
Price. The Company shall promptly send (by facsimile and by either first class
mail, postage prepaid or overnight delivery) a copy of each such certificate to
the Holder.

6. LOSS OR MUTILATION. Upon receipt of evidence reasonably satisfactory to the
Company of the ownership of and the loss, theft, destruction or mutilation of
this Warrant, and of indemnity reasonably satisfactory to it, and (in the case
of mutilation) upon surrender and cancellation of this Warrant, the Company will
execute and deliver in lieu thereof a new Warrant of like tenor as the lost,
stolen, destroyed or mutilated Warrant.

7. RESERVATION OF COMMON STOCK. The Company hereby covenants that at all times
there shall be reserved for issuance and delivery upon exercise of this Warrant
such number of shares of Common Stock or other shares of capital stock of the
Company as are from time to time issuable upon exercise of this Warrant and,
from time to time, will take all steps necessary to amend its Certificate of
Incorporation to provide sufficient reserves of shares of Common Stock issuable
upon exercise of this Warrant (and shares of its Common Stock for

                                      -6-

issuance on conversion of such Common Stock). All such shares shall be duly
authorized, and when issued upon such exercise, shall be validly issued, fully
paid and non-assessable, free and clear of all liens, security interests,
charges and other encumbrances or restrictions on sale and free and clear of all
preemptive rights, except encumbrances or restrictions arising under federal or
state securities laws and the Investors Agreement. Issuance of this Warrant
shall constitute full authority to the Company's officers who are charged with
the duty of executing stock certificates to execute and issue the necessary
certificates for shares of Common Stock (and shares of Common Stock for issuance
on conversion of such Common Stock) upon the exercise of this Warrant.

8. TRANSFER AND EXCHANGE. Upon the closing of the Company's IPO and after Intel
Corporation has fully vested all shares of Common Stock pursuant to the
conditions described in Attachment A hereto, subject to the terms and conditions
of this Warrant and compliance with all applicable securities laws, this Warrant
and all rights hereunder may be transferred to any Registered Holder parent,
subsidiary or affiliate, in whole or in part, on the books of the Company
maintained for such purpose at the principal office of the Company referred to
above, by the Registered Holder hereof in person, or by duly authorized
attorney, upon surrender of this Warrant properly endorsed and upon payment of
any necessary transfer tax or other governmental charge imposed upon such
transfer. Upon any permitted partial transfer, the Company will issue and
deliver to the Registered Holder a new Warrant or Warrants with respect to the
shares of Common Stock not so transferred. Each taker and holder of this
Warrant, by taking or holding the same, consents and agrees that when this
Warrant shall have been so endorsed, the person in possession of this Warrant
may be treated by the Company, and all other persons dealing with this Warrant,
as the absolute owner hereof for any purpose and as the person entitled to
exercise the rights represented hereby, any notice to the contrary
notwithstanding; provided, however that until a transfer of this Warrant is duly
registered on the books of the Company, the Company may treat the Registered
Holder hereof as the owner for all purposes.

         In addition, the Holder agrees that upon exercise (in full or in part)
of this Warrant, the Holder shall become a party to the Company's Third Amended
and Restated Investors Agreement dated as of January 7, 2000 by and among the
Company and certain of the holders of the Company's securities (the "Investors
Agreement"), that the Holder shall be deemed to be an "Investor" under the
Investors Agreement, that the Common Stock will be deemed to be "Investor Stock"
under the Investors Agreement, and that the Common Stock will be subject to all
restrictions contained in the Investors Agreement to the extent such
restrictions have not terminated.

9. RESTRICTIONS ON TRANSFER. The Holder, by acceptance hereof, agrees that,
absent an effective registration statement filed with the SEC under the
Securities Act of 1933, as amended (the "1933 Act"), covering the disposition or
sale of this Warrant or the Common Stock issued or issuable upon exercise
hereof, as the case may be, and registration or qualification under applicable
state securities laws, such Holder will not sell, transfer, pledge, or
hypothecate any or all such Warrants or Common Stock, as the case may be, unless
(A) the conditions and restriction of Section 8 above have been met, and (B)
either (i) the Company has received an opinion of counsel, in form and substance
reasonably satisfactory to the Company, to the effect

                                      -7-

                                                      INTEL/VELOCOM CONFIDENTIAL

that such registration is not required in connection with such disposition or
(ii) the Company is reasonably satisfied that the sale of such securities is
made pursuant to SEC Rule 144.

10. COMPLIANCE WITH SECURITIES LAWS. By acceptance of this Warrant, the Holder
hereby represents, warrants and covenants that any shares of Common Stock
purchased upon exercise of this Warrant shall be acquired for investment only
and not with a view to, or for sale in connection with, any distribution
thereof; that the Holder has had such opportunity as such Holder has deemed
adequate to obtain from representatives of the Company such information as is
necessary to permit the Holder to evaluate the merits and risks of its
investment in the Company; that the Holder is able to bear the economic risk of
holding such shares as may be acquired pursuant to the exercise of this Warrant
for an indefinite period; that the Holder understands that the shares of Common
Stock acquired pursuant to the exercise of this Warrant will not be registered
under the 1933 Act (unless otherwise required pursuant to exercise by the Holder
of the registration rights, if any, previously granted to the Holder) and will
be "restricted securities" within the meaning of Rule 144 under the 1933 Act and
that the exemption from registration under Rule 144 will not be available for at
least one year from the date of exercise of this Warrant, subject to any special
treatment by the SEC for exercise of this Warrant pursuant to Section 2.2, and
even then will not be available unless a public market then exists for the
stock, adequate information concerning the Company is then available to the
public, and other terms and conditions of Rule 144 are complied with; and that
all stock certificates representing shares of Common Stock issued to the Holder
upon exercise of this Warrant may have affixed thereto a legend substantially in
the following form:

     THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
     UNDER THE SECURITIES ACT OF 1933 OR ANY STATE SECURITIES LAWS. THE
     SECURITIES REPRESENTED BY THIS CERTIFICATE MAY NOT BE TRANSFERRED, SOLD,
     OFFERED FOR SALE OR OTHERWISE DISPOSED OF UNLESS THERE IS AN EFFECTIVE
     REGISTRATION STATEMENT OR OTHER QUALIFICATION RELATING TO SUCH SECURITIES
     UNDER THE SECURITIES ACT OF 1933 AND ANY APPLICABLE STATE SECURITIES LAWS
     OR UNLESS THE CORPORATION RECEIVED AN OPINION OF COUNSEL SATISFACTORY TO
     THE CORPORATION THAT SUCH REGISTRATION OR OTHER QUALIFICATION UNDER THE
     SECURITIES ACT OF 1933 AND ANY APPLICABLE STATE SECURITIES LAWS IS NOT
     REQUIRED IN CONNECTION WITH SUCH TRANSFER, SALE, OFFER OR DISPOSITION.

     THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A THIRD
     AMENDED AND RESTATED INVESTORS AGREEMENT, DATED AS OF JANUARY 7, 2000, AS
     AMENDED (THE "INVESTORS AGREEMENT") AMONG VELOCOM INC. (THE "CORPORATION")
     AND CERTAIN OF THE CORPORATION'S STOCKHOLDERS. A COPY OF SUCH INVESTORS
     AGREEMENT WILL BE FURNISHED WITHOUT CHARGE BY THE CORPORATION TO THE HOLDER
     HEREOF UPON WRITTEN REQUEST.

Holder to any voting rights or other rights as a stockholder of the Company. In

of this Warrant, but will at all times in good faith assist in the carrying out
of all such terms and in the taking of all such action as may be necessary or
appropriate in order to protect the rights of the Registered Holder of this
Warrant against impairment. Without limiting the generality of the foregoing,
the Company (a) will not increase the par value of any shares of stock issuable

exercise, and (b) will take all such action as may be necessary or appropriate
in order that the Company may validly and legally issue fully paid and
non-assessable shares of Common Stock upon exercise of this Warrant and Common
Stock issued in conversion thereof.

this Warrant enter into any agreement with respect to its securities which is
inconsistent with the rights granted to the Holders of this Warrant or otherwise
conflicts with the provisions hereof. The rights granted to the Holders
hereunder do not in any way conflict with and are not inconsistent with the
rights granted to holders of the Company's securities under any other
agreements, except rights that have been waived. Nothing herein will restrict
the ability of the Company to issue securities senior in right to the Common
Stock.

                         SALES AND MARKETING MILESTONES

All terms not defined herein shall have the definition assigned to them in that
Intel - Velocom Marketing Activities Agreement dated as of February __, 2000.
Performance milestones, to be performed sequentially, which trigger the vesting
of one hundred and twenty five thousand (125,000) shares of Warrant Stock (the
"Warrant Shares") issuable upon exercise of the Warrant are as follows:

MILESTONE 1. The right to exercise 40% of the shares shall vest upon Intel
extending VeloCom Affiliates a bona fide offer to participate in Intel channel
training events occurring on or before December 31, 2000. The offer will be for
a total of three (3) South American initial cities. VeloCom Affiliates may
participate in the training within a particular country, assuming VeloCom
Affiliates has announced commercial service for Internet or data services
within the country, or the announcement is within a month after the training.
Upon VeloCom Affiliates confirming it plans to participate in the training, then
Intel shall notify the Resellers in advance of the training regarding VeloCom
Affiliates' participation by: 1) sending an email-blast to the Resellers prior
to the training, highlighting VeloCom Affiliates inclusion; and 2) highlighting
VeloCom Affiliates service at the training. Should VeloCom Affiliates for any
reason not be able to support the marketing program trial and participate in the
Reseller training in Brazil or Argentina by December 31, 2000, the conditions
for Milestone 1 will be deemed satisfied and the Warrant Shares associated with
Milestone 1 shall vest.

MILESTONE 2. The right to exercise 40% of the Warrant Shares shall vest upon
Intel's delivering to VeloCom Affiliates the Reseller contact names and phone
numbers and mailing introductory electronic mail, letters, or similar
communications from the Intel country manager to the pre-selected Reseller
segment a) explaining the strategic relationship between the Parties, b)
positioning VeloCom Affiliate services as an important link in the internet
economy, c) explaining the benefits to the Reseller of entering into an
agreement with VeloCom Affiliates, d) providing the contact name at VeloCom
Affiliates. As defined in Section 2 of the Agreement, Intel shall select
Resellers from its channel with the technical orientation and/or proven
capabilities to sell services. As Intel is not a party to the sales agreement
between VeloCom Affiliates and the independent Resellers, does not have any
control over what sells in a given market, and does not have responsibility or
control over the quality and competitiveness of VeloCom Affiliates service or
offer to the Resellers, the satisfaction of Milestone 2 will not be based on any
pre-defined number of Resellers that choose to participate, nor on predefined
sales target numbers. The consideration flowing from Intel to VeloCom is Intel's
introductory communications to the Resellers and the Reseller list derived from
the pre-selection process, which will be based on data collected by Intel from
the Resellers, developed by Intel and protected as Intel confidential
information. Intel will select from its Reseller channels, those that have
purchased from Intel server motherboards, high end microprocessors, small/medium
networking equipment, and related products. The conditions for Milestone 2 will
be deemed to have been satisfied and the Warrant Shares associated with
Milestone 2 shall vest upon Intel's providing the above deliverables,
independent of whether VeloCom Affiliates, for any reason, undertakes or elects
not to undertake, the channel expansion effort with these Resellers.

MILESTONE 3. The remaining 20% of the Warrant Shares shall vest upon VeloCom
Affiliates and Intel launching the Marketing and Sales Program described in
Sections 1 and 2 of the Agreement, in an

                                      -14-
<PAGE>   66

additional city, either in Brazil, Argentina or an additional country, to be
named by VeloCom. This city must be selected no later than March 31, 2001 with
the intent of ramping the program and services within nine (9) months of the
selection. The conditions for Milestone 3 will be deemed to have been satisfied
upon Intel making a bona fide offer to VeloCom Affiliates to participate in
training events in an additional city covered by VeloCom Affiliates' rollout
plan, and delivering to VeloCom Affiliates the target lists for sales
development. If no additional city is selected by VeloCom Affiliates by March
31, 2001, then the conditions for Milestone 3 will be deemed to have been
satisfied and the Warrant Shares associated with Milestone 3 shall vest.

Notwithstanding anything to the contrary in the Agreement, upon the occurrence
of a Corporate Event (defined below), the Warrant will become fully vested and
immediately exercisable as to all of the Warrant Shares. For purposes of
determining the number of shares covered under this paragraph the conditions
precedent to coverage shall be deemed fulfilled for each group of shares
described above, except to the extent that Intel has failed to fulfill a
condition precedent for a group of shares where the cut-off date for such
fulfillment precedes the date of the subject Corporate Event. The term
"Corporate Event" shall mean: (1) a consolidation or merger of VeloCom with or
into any other corporation or corporations; (2) a sale, conveyance or
disposition of all or substantially all of the assets of VeloCom ; (3) the
effectuation by VeloCom of a transaction or series of related transactions in
which more than 50% of the voting power of VeloCom is disposed of except in
connection with capital raisings; or (4) any affirmative action by VeloCom or a
Velocom Affiliate that would prevent Intel from fulfilling any of its proposed
obligations under the Agreement. Notwithstanding the foregoing, 'Corporate
Event' shall not include mergers, reorganizations or other transactions that are
internal to VeloCom and its subsidiaries and do not (1) materially affect
VeloCom' ultimate indirect ownership of the assets owned by the entities engaged
in such transaction or (2) affect Intel's ability to fulfill its proposed
obligations under the Agreement. The occurrence of a corporate event shall not
relieve Intel of its obligations hereunder.

                    INTERNET AND DATA PERFORMANCE MILESTONES

Performance milestones which, if not met by VeloCom, trigger the vesting of up
to one hundred and twenty five thousand (125,000) shares of Warrant Stock (the
"Warrant Shares") issuable upon exercise of the Warrant are as follows:

Fifty percent (50%) of the total unvested Warrant Shares as of December 31, 2000
shall vest and become exercisable should VeloCom not achieve revenues earned by
VeloCom Affiliates other than Telelatina for offering Internet and data services
in the calendar year 2000 of at least equal to the size of Intel's total equity
investment of $5,000,000 in VeloCom. An additional fifty percent (50%) of the
total unvested Warrant Shares as of December 31, 2000 shall vest and become
exercisable should the total Internet and data customers achieved by VeloCom
Affiliates other than Telelatina not total at least 50,000 on December 31, 2000.
The term "Internet or data customer" shall mean a unique household or business
customer location (street address) which was being provided Internet access or
other data transmission services on December 31, 2000. Velocom will provide
Intel on or before February 28, 2001 a written summary of: i) total Internet and
data services revenues (in equivalent U.S. dollar terms) earned by each entity
making up the Velocom Affiliates in calendar year 2000; and ii) total Internet
and data customers on December 31, 2000 for each entity making up the Velocom
Affiliates.

                              FORM OF LEGAL OPINION

         We are of the opinion that:

         1. The Company is a corporation duly incorporated, validly existing and
in good standing under the laws of the State of Delaware, with full corporate
power and authority to own, lease and operate its properties and to conduct its
business. The Company is qualified to do business and in good standing in each
jurisdiction in the United States where the failure to be so qualified would
result in a material adverse effect on the business, operations, assets,
prospects or condition (financial or otherwise) of the Company (a "Material
Adverse Effect").

         2. The authorized capital stock of the Company, immediately prior to
the Closing Date, shall consist of (a) one hundred nine million seven hundred
fifty nine thousand four hundred twenty one (109,759,421) shares of Common
Stock, of which (i) one hundred seven million seven hundred ninety one thousand
six hundred sixty seven (107,791,667) will be designated as Voting Common Stock,
eleven million two hundred eighty three thousand eight hundred twenty six
(11,283,826) of which will be issued and outstanding immediately prior to the
Closing Date, and (ii) one million nine hundred sixty seven thousand seven
hundred fifty four (1,967,754) will be designated as Non-Voting Common Stock,
none of which will be issued and outstanding immediately prior to the Closing
Date, and (b) seventy nine million six hundred thirty four thousand four hundred
twenty one (79,634,421) shares of Preferred Stock, of which (i) thirty one
million (31,000,000) will be designated as Series A Preferred Stock, thirty
million seven hundred six thousand three hundred thirty three (30,706,333) of
which will be issued and outstanding immediately prior to the Closing Date, (ii)
forty two million six hundred sixty six thousand six hundred sixty seven
(42,666,667) will be designated as Series B Preferred Stock, of which nineteen
million three hundred three thousand and seventy eight (19,303,078) will be
issued and outstanding immediately prior to the Closing Date, and (iii) one
million nine hundred sixty seven thousand seven hundred fifty four (1,967,754)
will be designated as Series B-1 Preferred Stock, all of which shares will be
issued and outstanding immediately prior to the Closing Date. To our knowledge,
except for the six million two hundred ninety thirty three thousand three
hundred thirty three (6,233,333) options outstanding immediately prior to the
Closing Date, except for the conversion privileges of the Series A Preferred
Stock, Series B Preferred Stock and Series B-1 Preferred Stock, except for the
shares of Series B Preferred Stock to be purchased pursuant to the Series B
Preferred Stock Purchase Agreement dated as of December 6, 1999 among the
Company and the Purchasers listed on the Schedule of Purchasers attached
thereto, as amended by Amendment No. 1 thereto, dated as of December 31, 1999,
except for the shares of Series B Preferred Stock and Series B-1 Preferred Stock
to be purchased pursuant to the Follow-On Series B/B-1 Preferred

                                       1
<PAGE>   75

Stock Purchase Agreement dated as of December 20, 1999 among the Company and the
Purchasers listed on the Schedule of Purchasers attached thereto, and except as
disclosed in the Agreements or the exhibits or schedules attached thereto, there
are no options, warrants, conversion privileges, preemptive rights, rights of
first refusal or other rights to purchase from the Company any of its equity
securities that are outstanding immediately prior to the Closing Date.

         3. All the shares of capital stock of the Company outstanding prior to
the Closing Date have been duly authorized, validly issued and are fully paid
and nonassessable. The rights, preferences and privileges of the Series B
Preferred Stock are as stated in the Certificate of Incorporation.

         4. To our knowledge, Schedule 3.12 to the Purchase Agreement sets forth
the ownership structure of the Company and its Subsidiaries.

         5. Each of the Agreements has been duly authorized, validly executed
and delivered by the Company and is a valid and binding agreement of the
Company, enforceable against the Company in accordance with its terms, except as
rights to indemnity under Section 2.5 of the Investors Agreement may be limited
by applicable laws and public policy and except as enforcement may be limited by
applicable bankruptcy, insolvency, reorganization, arrangement, moratorium or
other similar laws affecting creditors' rights, and subject to general equity
principles and to limitations on availability of equitable relief, including
specific performance.

         6. The issuance, sale and delivery of the Series B Preferred Stock
pursuant to the Purchase Agreement has been duly authorized by the Company and,
upon delivery to the Purchasers against payment therefor in accordance with the
Purchase Agreement and the terms of the Series B Preferred Stock, the shares of
Series B Preferred Stock will be validly issued, fully paid and nonassessable.

         7. The shares of Common Stock to be issued upon conversion of the
Series B Preferred Stock have been duly authorized and reserved for issuance by
the Company and, when issued and delivered upon conversion of the Series B
Preferred Stock in accordance with the Certificate of Incorporation, such shares
of Common Stock will have been validly issued and will be fully paid and
nonassessable.

         8. The execution of the Agreements by the Company, the compliance by
the Company with the terms thereof, and the offer and sale of the Series B
Preferred Stock pursuant to the Purchase Agreement (a) do not and will not
violate any provision of the Company's Certificate of Incorporation or Bylaws,
and (b) do not violate or contravene (i) the laws of the State of Colorado, the
General Corporation Law of the State of Delaware or any Federal law of the
United States of America applicable to the Company or (ii) any order, writ,
judgment, injunction, decree, determination or award which has been entered
against the Company and of which we have knowledge, the default, violation or
contravention of which would materially and adversely affect the Company, its
assets, financial condition or operations.

                                       2
<PAGE>   76

         9. All consents, approvals, authorizations or orders of, and filings,
registrations, and qualifications with, any regulatory authority or governmental
body in the United States required for the consummation by the Company of the
transactions contemplated by the Purchase Agreement have been made or obtained,
except for any filings required under federal or state securities laws, and
except for any filings required under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended.

         10. To our knowledge, there is no suit, action, claim, arbitration or
similar proceeding or investigation pending or threatened against the Company or
against the Company's business or assets which, if adversely resolved, would be
reasonably likely to have a Material Adverse Effect.

         11. Subject to the accuracy of the Purchasers' representations in
Section 4 of the Purchase Agreement and assuming all required filings are made
under federal and state securities laws, the offer, sale and issuance of the
Series B Preferred Stock pursuant to the Purchase Agreement constitutes a
transaction exempt from the registration requirements of Section 5 of the
Securities Act of 1933, as amended (the "Securities Act") and from the
securities registration requirements of the Colorado securities laws. In
addition, subject to the accuracy of the Purchasers' representations in Section
4 of the Purchase Agreement, assuming such securities are not being exchanged in
a case under title 11 of the United States Code, and assuming no commission or
other remuneration is paid or given directly or indirectly for soliciting such
exchange, the issuance of the Common Stock issuable upon conversion of the
Series B Preferred Stock would also constitute a transaction exempt from the
registration requirements of Section 5 of the Securities Act and from the
securities registration requirements of the Colorado securities laws.

with the terms and requirements of all Permits, except for any such

will be, timely filed prior to the Closing, except as would not have a Material
Adverse Effect, (iv) no proceeding or other legal action to modify, suspend,
revoke, withdraw, terminate or otherwise limit any such Permit is pending or, to
the knowledge of the Company, threatened, except for such proceedings or actions
which would not have a Material Adverse Effect, and (v) each of the Companies
has made all payments required to be made under all Permits, including, without
limitation, in respect of any Licenses, except for payments the failure of which
to make would not have a Material Adverse Effect.

trademarks, trade names, service marks, service names, copyrights and other

Person challenging the right of any of them to use any such Patent and Trademark
Rights owned or used by or licensed to each of the Companies. The Company has no
knowledge that any Patent and Trademark Right is being infringed upon or
appropriated by others, and none is subject to any outstanding Judgment
affecting the scope of the free and unrestricted use by any of the Companies or
is used contrary to the provisions of any licensing or other agreement. There
are no geographic restrictions on the use by any of the Companies of the Patent
and Trademark Rights, except as would not have a Material Adverse Effect.

arrangement for the provision or acquisition of any Patent and Trademark Rights.

         3.7 Actions Pending. There is no suit, action, claim, arbitration or
similar proceeding or investigation pending or, to the Company's knowledge,
threatened against any of the Companies (i) which, if adversely resolved, would
be reasonably likely to have a Material Adverse Effect, (ii) with respect to
which there is a reasonable likelihood of a determination which would prevent
the Company from consummating the transactions contemplated by the Transaction
Documents, or (iii) which seeks to enjoin or obtain damages in respect of the
consummation of the transactions contemplated by the Transaction Documents. None
of the Companies is a party to or is bound by any Judgment of any governmental
authority, arbitrator or any other Person. None of the Companies has
compromised, settled or lost any arbitration or judicial or administrative
proceeding.

         3.8 Contracts.

               (a) Schedule 3.8 contains an accurate and complete list of all
Contracts to which any of the Companies is a party or by which any of such
Companies' assets or properties are bound or affected and which (i) involve the
obligation (including contingent obligations) to pay by or to any of such

aggregate in respect of the Brazilian Companies, (ii) are Contracts with any
stockholder or member or any Affiliate of any stockholder or member, (iii) are

the respective Companies in accordance with their respective terms and none of
such Companies is in default under any of such Contracts nor is there any basis
for any valid claim of default or violation under any Contract, except, in each
case, as would not have a Material Adverse Effect. To the knowledge of the
Company, no other party to any of such Contracts is in default in any material
respect thereunder nor does there exist any event or condition, which upon the
giving of notice or the lapse of time or both, would (i) constitute a default in
any material respect or event of default thereunder or (ii) entitle any other
party thereto to terminate such Contract.

               (c) None of the Companies is a party to any Contract containing
an undertaking on its part not to compete in any business, industry or
geographical area except as set forth in the Licenses.

         3.9 Investments in United States Real Property Interests. The Company's
capital stock does not, and the Company shall use its reasonable commercial
efforts to ensure that its capital stock will not, constitute a United States
real property interest as that term is defined in Section 897(c)(1)(A)(ii) of
the Internal Revenue Code of 1986, as amended (the "Code"). The preceding
representation is based on a determination by the Company that the Company is
not and has not been a United States real property holding corporation (as that
term is defined in Section 897(c)(2) of the Code) ("USRPHC") during the five (5)
year period preceding the date of this Agreement. From time to time, upon the
request of any Purchaser, the Company shall make a determination as to its
status as a USRPHC. If at any time in the future the Company should become a
United States real property holding corporation, the Company shall, as promptly
as possible, notify each Purchaser of such change in status.

         3.10 Unrelated Business Taxable Income. The Company shall use its
reasonable commercial efforts to ensure that any gross income derived by a
Purchaser from the Company shall be in the form of dividends, interest, capital
gains and losses from the disposition of property, and rents and royalties, but
only such rents and royalties as are excluded pursuant to Code Sections
512(b)(2) and 512(b)(3), respectively, in calculating unrelated business taxable
income and only such dividends,

                                       6
<PAGE>   11

interest, capital gains and losses, and rents and royalties that are not
included under Section 512(b)(4) of the Code in calculating unrelated business
taxable income.

         3.11 Not a Qualified Small Business. The Company does not qualify as a
"Qualified Small Business" as defined in Section 1202(d) of the Code.

         3.12 Ownership of Companies. Schedule 3.12 sets forth the ownership
structure of the Companies.

         3.13 Capitalization of the Company's Subsidiaries Schedule 3.13 sets
forth the outstanding capital of each of the Companies (other than the Company),
the number of their authorized and issued shares or equity interests and their
nominal value. All of the shares or equity interests of the Companies (other
than the Company) have been duly authorized, validly issued and are fully paid
and non-assessable. The Companies (other than the Company) have no other shares
or equity interests of any kind authorized or outstanding, no outstanding
securities convertible into or exchangeable for or carrying the right to acquire
any equity security of any of the Companies (other than the Company) and no
outstanding options, warrants or other agreements or commitments under which any
of the Companies (other than the Company) are obligated to issue any additional
shares or equity interests. None of the shares of any of the Companies is
subject to any Encumbrances except as set forth on Schedule 3.13, except that
the shares of Vesper S.A. and Vesper Sao Paulo S.A. are pledged pursuant to the
terms of the Vendor Financings, and except as contemplated or granted in the
Transaction Documents.

         3.14 Share Ownership.

               (a) Schedule 3.14(a) sets forth the true and correct
capitalization of the Company immediately prior to and immediately after the
Closing Date.

               (b) Schedule 3.14(b) sets forth a true and complete list of (i)
all stockholders agreements, investors agreements, limited liability company
agreements or other agreements in respect of or relating to the equity interests
in the Companies to which the Company or any of the Companies is a party, and
(ii) all Contracts relating to the purchase, sale, transfer or other disposition
of any securities or equity interests of any of the Companies to which the
Company or any of the Companies is a party.

         3.15 Financial Statements. The Company has delivered to each Purchaser
(x) the audited balance sheet and the related audited income statement and
retained earnings statement for the year ended December 31, 1998 of the Company,
and (y) unaudited balance sheet and the related unaudited income statement and

               (a) The Companies have filed all federal, state, departmental,

imposition of significant penalties on any of the Companies, each of the
Companies has paid all such taxes that have already become due and payable. The

there are no circumstances which, either by passage of time or issuance of an
assessment binding on any of the Companies to pay any Tax or contribution, may
give rise to any type of dispute with any Tax authority in relation to any Tax
obligation or liability.

                                       11
<PAGE>   16

Memorandum dated as of July 1999, as supplemented by the October 1999
Supplemental Disclosure Statement, provided to the Purchasers, except where the
failure to have such allocation will not have a Material Adverse Effect on any
of the Companies; provided that in respect of the Brazilian Companies, in the
event any such Brazilian Company needs additional spectrum to satisfy its
current business plan objectives, the Company reasonably believes that such
spectrum should be available from ANATEL so long as such Brazilian Company has
complied with its existing license obligations. Vesper Sao Paulo S.A. and Vesper
S.A. have the exclusive right to use the frequencies 1940-1950 Mhz (10 Mhz of
which are in reserve) and 3425-3450, 3525-3550 Mhz (30 Mhz of which are in
reserve) in the bands granted to them under their respective concessions in
their respective service areas until December 31, 2001, subject to the terms of
the concessions and for so long as such companies remain in compliance with the
terms of their respective concessions. Vesper Sao Paulo S.A. and Vesper S.A.
share the following frequencies with the incumbent service providers in their
regions: 1910-1930 Mhz, 406-413 Mhz and 423-430 Mhz. The incumbent operators
currently have the right to use the 1.9 Ghz frequencies that they share with
Vesper S.A. and Vesper Sao Paulo S.A. for cities having populations of 50,000 or
less. Commencing in February 2001, with respect to Vesper S.A., and May 2001,
with respect to Vesper Sao Paulo S.A., these incumbent operators may continue to
use the shared 1.9 Ghz frequencies provided that they reach a mutually agreeable
use agreement with Vesper S.A. and Vesper Sao Paulo S.A. and ANATEL approves of
such use agreement.

         3.30 Disclosure.

               (a) No representation or warranty by the Company in this
Agreement or any other Transaction Document contains any untrue statement of a
material fact or omits to state any material fact necessary, in light of the
circumstances under which it was made, in order to make the statements herein or
therein not misleading. Documents delivered or to be delivered to the Purchasers
or their counsel pursuant to this Agreement and the other Transaction Documents
are or will be true and complete copies in all material respects of what they
purport to be.

               (b) The business and strategy of the Company described in the
Confidential Offering Memorandum dated July 1999, as supplemented by the October
1999 Supplemental Disclosure Statement, is the business and strategy that the
Company is pursuing as of the date hereof except for (i) the sale of the
Company's assets in Peru and Colombia, (ii) the purchase of internet assets in
Brazil, (iii) the creation of a data transport and data warehouse business in
Brazil, (iv) a greater focus on the Mercosur countries and Mexico, and (v) the
possible pursuit of the acquisition of cable assets in the Mercosur region. The
financial projections in respect of Vesper Sao Paulo

                                       12
<PAGE>   17

S.A. and Vesper S.A. contained in the October 1999 Supplemental Disclosure
Statement prepared by the Company and provided to El Paso Energy Communications
Company ("El Paso") were prepared in good faith and were based upon reasonable
assumptions. Each Purchaser acknowledges that Vesper Sao Paulo S.A. and Vesper
S.A. are in the process of reexamining the operating and capital expenditures
and capital requirements for their respective businesses and that the Advisory
Committees of each of Vesper Sao Paulo S.A. and Vesper S.A. is considering the
adoption of revisions to their respective business plans primarily to accelerate
the development of its network and to implement a data transport business, but
no Advisory Committee has yet approved such revisions to the business plans. Any
such revision to the business plans would likely change the financial
projections of Vesper Sao Paulo S.A. and/or Vesper S.A. The approval of the
Board of Directors of the Company will be obtained before Vesper Sao Paulo S.A.
or Vesper S.A. approves any material changes to their business plans.

has any direct or indirect ownership interest in any firm or corporation with
which the Company is affiliated or with which the Company has a business

1% of the stock in publicly traded companies that may compete with the Company).

Company contain since the time of incorporation complete and accurate records in
all of all meetings and other corporate actions of the stockholders and Board of
Directors (and any committees thereof) of the Company.

Agreement, the Company is not under any contractual obligation to register under
the Securities Act any of its currently outstanding securities or any of its

Agreement nor any term hereof may be amended, waived, discharged or terminated
except by a written instrument signed by the Company and the holders of a
majority of the Shares held by the Purchasers, and any such amendment, waiver,
discharge or termination shall be binding on all Purchasers, except that if such
amendment, waiver, discharge or termination creates an obligation by any
Purchaser, or if it adversely affects a particular Purchaser in a manner
different from the other Purchasers, the consent of the affected Purchaser shall
be required.

         7.5 Specific Enforcement. Any Purchaser shall be entitled to specific
enforcement of its rights under this Agreement. Each party acknowledges that
money damages would be an inadequate remedy for its breach of this Agreement and
consents to an action for specific performance or other injunctive relief in the
event of any such breach.

         7.6 Termination. If any of the closing conditions contained in Section
5 hereof have not been satisfied or waived by June 30, 2000, then either party
may terminate this Agreement by providing written notice to the other party of
its intent to terminate under this paragraph.

         7.7 Severability. Unless otherwise expressly provided herein, a
Purchaser's rights hereunder are several rights, not rights jointly held with
any of the other Purchasers. In case any provision of this Agreement shall be
invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

         7.8 Notices. All notices required or permitted hereunder shall be in
writing and shall be deemed effectively given: (i) upon personal delivery to the
party to be notified; (ii) when sent by confirmed telex or facsimile if sent

day; (iii) five (5) days after having been sent by registered or certified mail,

         7.9 Counterparts; Facsimile. This Agreement may be executed in any
number of counterparts, each of which shall be an original, but all of which
together shall constitute one instrument. This Agreement may be executed and
delivered by facsimile.

         7.10 Future Financings; Purchaser Obligations. Nothing contained in
this Agreement or any Purchaser's prior dealings with the Company shall be
deemed to constitute a commitment on the part of any Purchaser to participate in
any future financings by the Company. In connection with any merger involving
the Company, the

                                       18

indemnification obligations of each Purchaser (if any) shall be several and not
joint, and shall in no event exceed the amount of consideration to be received
by such Purchaser in the merger.

         7.11 Expenses. Each party hereto shall pay all fees and expenses
incurred by such party in connection with the negotiation and preparation of the
Transaction Documents and the consummation of the transactions contemplated
therein.

         7.12 Indemnification.

               (a) Indemnification by the Company. The Company shall indemnify
and hold each Purchaser harmless from and against any and all damages, losses,
liabilities, actions, suits, proceedings (including any inquiry or investigation
with respect thereto), claims, costs or expenses, including reasonable
attorneys' fees (collectively, the "Damages"), resulting from, arising out of or
in any way related to, any breach of a representation, warranty or covenant made
by the Company pursuant to this Agreement.

               (b) Indemnification by the Purchasers. Each Purchaser shall,
severally and not jointly, indemnify and hold the Company harmless from and
against any and all Damages resulting from, arising out of or in any way related
to, any breach of a representation, warranty or covenant made by such Purchaser
pursuant to this Agreement.

               (c) Claims. Any party claiming a right to indemnification under
this Section 7.12, respectively (an "Indemnified Party"), shall give prompt
written notice to the other party (the "Indemnifying Party") of (i) the
incurrence of Damages or (ii) the institution of any actions, suits, proceedings
(including any inquiry or investigation with respect thereto), each in
connection with which the Indemnified Party would be entitled to claim
indemnification from the Indemnifying Party under this Section 7.12
(respectively, "Indemnifiable Claims"), which written notice shall set forth the
nature of the Indemnifiable Claim, the factual basis therefor and shall
reference this Section 7.12.

               (d) Third Party Claims. The respective obligations and
liabilities of each of the Purchasers and the Company regarding any
Indemnifiable Claims resulting from claims made by third parties ("Third Party
Claims") shall be subject to the following terms and conditions: The Indemnified
Party shall give the Indemnifying Party prompt written notice of any Third Party
Claims. If the Indemnified Party fails to give such prompt notice to the
Indemnifying Party, the Indemnified Party shall not forfeit its Third Party
Claims except to the extent that the Indemnifying Party has been prejudiced
thereby. Upon notice from the Indemnified Party, the Indemnifying Party may, but
shall not be required to, assume the defense of any such Third Party Claim,
including its compromise or settlement, and the Indemnifying Party shall pay all
reasonable costs and expenses thereof and shall be fully responsible for the
outcome thereof. The Indemnifying Party shall give notice to the Indemnified
Party of its intention to assume the defense of any such Third Party Claims
within ten (10) business

                                       19
<PAGE>   24

days after the date of receipt of the Indemnified Party's notice in respect of
such Third Party Claims. No compromise or settlement in respect of any Third
Party Claims may be effected by the Indemnifying Party without the Indemnified
Party's prior consent (which consent shall not be unreasonably withheld). The
Indemnifying Party shall have no liability with respect to any compromise or
settlement thereof effected without its prior consent (which consent shall not
be unreasonably withheld). The Indemnifying Party shall not consent to, and the
Indemnified Party shall not be required to consent to, any settlement or entry
of any judgment that does not include as an unconditional term thereof the
giving by claimant or plaintiff to the Indemnified Party of a release, in form
and substance satisfactory to the Indemnified Party or Parties, from all
liabilities in respect of such claim, litigation or proceeding. If an
Indemnifying Party does not, within ten (10) business days after the Indemnified
Party's notice is given, give notice to the Indemnified Party of its assumption
of the defense of the Third Party Claims, the Indemnifying Party shall be deemed
to have waived its rights to control the defense thereof; provided, that the
Indemnifying Party shall be entitled to participate, at its own cost and
expense, in the defense of such Third Party Claims and the Indemnified Party
shall fully cooperate with the Indemnifying Party in respect of the defense of
such Third Party Claims. In the event that the Indemnifying Party assumes the
defense of any Third Party Claims, it shall not be responsible or liable for any
further costs or expenses of legal counsel incurred by the Indemnified Party in
connection with the defense thereof unless agreed to in advance by such
Indemnifying Party. If the Indemnified Party assumes the defense of any Third
Party Claim in accordance with this Section 7.12, the Indemnifying Party shall
pay all reasonable costs and expenses of such defense.

         7.13 Survival. All representations and warranties contained in this
Agreement or certificate delivered in connection herewith shall survive for the
time period commensurate with the applicable statute of limitations.

                              FORM OF LEGAL OPINION

         We are of the opinion that:

         1. The Company is a corporation duly incorporated, validly existing and
in good standing under the laws of the State of Delaware, with full corporate
power and authority to own, lease and operate its properties and to conduct its
business. The Company is qualified to do business and in good standing in each
jurisdiction in the United States where the failure to be so qualified would
result in a material adverse effect on the business, operations, assets,
prospects or condition (financial or otherwise) of the Company (a "Material

and nonassessable. The rights, preferences and privileges of the Series C
Preferred Stock are as stated in the Certificate of Incorporation.

         4. To our knowledge, Schedule 3.12 to the Purchase Agreement sets forth
the ownership structure of the Company, its Subsidiaries and the Brazilian
Companies.

         5. The Company has the corporate power and authority to enter into the
Agreements and to issue, sell and deliver to the Purchasers shares of the Series
C Preferred Stock in accordance with the Purchase Agreement.

         6. Each of the Agreements has been duly authorized, validly executed
and delivered by the Company and is a valid and binding agreement of the
Company, enforceable against the Company in accordance with its terms, except as
rights to indemnity under Section 2.5 of the Investors Agreement may be limited
by applicable laws and public policy and except as enforcement may be limited by
applicable bankruptcy, insolvency, reorganization, arrangement, moratorium or
other similar laws affecting creditors' rights, and subject to general equity
principles and to limitations on availability of equitable relief, including
specific performance.

         7. The issuance, sale and delivery of the Series C Preferred Stock
pursuant to the Purchase Agreement has been duly authorized by the Company and,
upon delivery to the Purchasers against payment therefor in accordance with the
Purchase Agreement and the terms of the Series C Preferred Stock, the shares of
Series C Preferred Stock will be validly issued, fully paid and nonassessable.

         8. The shares of Common Stock to be issued upon conversion of the
Series C Preferred Stock have been duly authorized and reserved for issuance by
the Company and, when issued and delivered upon conversion of the Series C
Preferred Stock in accordance with the Certificate of Incorporation, such shares

violate any provision of the Company's Certificate of Incorporation or Bylaws,
and (b) do not

                                       2
<PAGE>   36

violate or contravene (i) the laws of the State of Colorado, the General
Corporation Law of the State of Delaware or any Federal law of the United States
of America applicable to the Company, (ii) any order, writ, judgment,
injunction, decree, determination or award which has been entered against the
Company and of which we have knowledge, the default, violation or contravention
of which would materially and adversely affect the Company, its assets,
financial condition or operations or (iii) any provision of the Series A
Preferred Stock Purchase Agreement dated as of January 26, 1999 among the
Company and the Purchasers on the Schedule of Purchasers attached thereto; the
Second Series A Preferred Stock Purchase Agreement dated as of May 7, 1999 among
the Company and the Purchasers on the Schedule of Purchasers attached thereto;
the Series B Preferred Stock Purchase Agreement dated as of December 6, 1999

dated as of December 20, 1999 among the Company and the Purchasers listed on the

         10. All consents, approvals, authorizations or orders of, and filings,
registrations, and qualifications with, any regulatory authority or governmental
body in the United States required for the consummation by the Company of the
transactions contemplated by the Purchase Agreement have been made or obtained,
except for any filings required under federal or state securities laws not
required to have been made as of the date hereof.

         11. To our knowledge, there is no suit, action, claim, arbitration or
similar proceeding or investigation pending or threatened against the Company or
against the Company's business or assets which, if adversely resolved, would,
individually or in the aggregate, be reasonably likely to have a Material
Adverse Effect.

         12. Subject to the accuracy of the Purchasers' representations in
Section 4 of the Purchase Agreement and assuming all required filings are made
under federal and state securities laws, the offer, sale and issuance of the
Series C Preferred Stock pursuant to the Purchase Agreement constitutes a
transaction exempt from the registration requirements of Section 5 of the
Securities Act of 1933, as amended (the "Securities Act") and from the
securities registration requirements of the Colorado securities laws. In
addition, subject to the accuracy of the Purchasers' representations in Section
4 of the Purchase Agreement, assuming such securities are not being exchanged in
a case under title 11 of the United States Code, and assuming no commission or
other remuneration is paid or given directly or indirectly for soliciting such
exchange, the issuance of the Common Stock issuable upon conversion of the
Series C Preferred Stock would also constitute a transaction exempt from the
registration requirements of Section 5 of the Securities Act and from the
securities registration requirements of the Colorado securities laws.
