                       SUMMARY OF TERMS OF THE EXCHANGE OFFER

     We will accept for exchange up to $142,800,000 aggregate principal amount
of Omnipoint's outstanding 14% Senior Notes due 2003 for up to $149,654,400
aggregate principal amount of our new registered 10 3/8% Senior Notes due 2009.

Background....................   Omnipoint has outstanding $142,800,000 in
                                 aggregate principal amount of its 14% Senior
                                 Notes due 2003, which it issued privately. On
                                 February 25, 2000, Omnipoint became our wholly
                                 owned subsidiary and we wish to replace its
                                 senior notes with senior notes that we have
                                 issued. Accordingly, we are offering to
                                 exchange $1,048 in aggregate principal amount
                                 of our 10 3/8 Senior Notes for each $1,000 in
                                 principal amount of Omnipoint's 14% Senior
                                 Notes.

Securities Offered............   We are offering up to $149,654,400 aggregate
                                 principal amount of our 10 3/8% Senior Notes
                                 due 2009, all of which will have been
                                 registered under the Securities Act of 1933.

The Exchange Offers...........   We are offering to accept Omnipoint's
                                 unregistered, outstanding notes in exchange for
                                 our new notes that will have been registered
                                 under the Securities Act of 1933. Upon
                                 accepting tenders of Omnipoint notes we will
                                 issue our new notes to the tendering holders.
                                 For procedures for tendering, see "The Exchange
                                 Offer." Our notes that are issued in exchange
                                 for the Omnipoint notes will be deemed to have
                                 accrued interest since November 9, 1999 unless
                                 they are issued after May 15, 2000, in which
                                 case they will be deemed to have accrued
                                 interest from that date. Tendering Omnipoint
                                 note holders will be required to pay us the
                                 amount of unpaid interest that is deemed to
                                 have accrued on our notes at the time of their
                                 issuance, and we will pay the tendering note
                                 holders the amount of accrued and unpaid
                                 interest on their Omnipoint notes to the same
                                 date.


Expiration of the Exchange
Offers........................   5:00 p.m., New York City time, on June 9, 2000,
                                 unless we extend it.


Tenders; Withdrawal...........   Omnipoint notes may be accepted for exchange at
                                 any time after they are tendered. See "The
                                 Exchange Offer." If for any reason any tendered
                                 notes are not accepted for exchange, they will
                                 be returned as soon as practicable after the
                                 expiration or termination of our exchange
                                 offer.

Conditions to the Exchange
Offer.........................   Our exchange offer is subject to the condition
                                 that it does not violate applicable law or any
                                 applicable interpretation of the staff of the
                                 commission. There is no guarantee that this
                                 condition will be satisfied.


Federal Income Tax
Considerations................   The exchange of our new notes for Omnipoint's
                                 outstanding notes pursuant to the exchange
                                 offer will constitute a taxable exchange

                                 exchange offer.

Use of Proceeds...............   We will not receive any cash proceeds from the
                                 issuance of the new notes in connection with
                                 the exchange offer.

Consequences If You Do Not
  Exchange Outstanding
  Notes.......................   Omnipoint's outstanding notes that are not
                                 tendered to us or are not accepted for exchange
                                 will continue to accrue interest and will
                                 continue to bear legends restricting their
                                 transfer. They may not be offered for sale or
                                 sold except:

                                 - Pursuant to an exemption from the
                                   registration requirements of the Securities
                                   Act of 1933; or

                                 - Pursuant to an effective registration
                                   statement under the Securities Act of 1933.

                                 Omnipoint does not anticipate that it will
                                 register any of its outstanding notes under the
                                 Securities Act of 1933.

                        SUMMARY DESCRIPTION OF OUR NEW NOTES

Notes Offered.................   $149,654,400 in principal amount of our 10 3/8%
                                 Senior Notes Due November 15, 2009. Upon
                                 maturity, we will pay the principal of,
                                 premium, if any, and interest on the senior
                                 notes in immediately available funds.

Maturity Date.................   November 15, 2009.

Yield and Interest............   Our notes will bear interest payable
                                 semiannually in arrears, at a rate of 10 3/8%
                                 per annum, on May 15 and November 15 of each
                                 year. Interest on our notes will be deemed to
                                 have begun accruing on November 9, 1999 (or May
                                 15, 2000 if they are issued after that date).

Ranking.......................   Our notes will be senior unsecured obligations
                                 of ours. As such, they:

                                 - will rank equal in right of payment with all
                                   of our other senior unsecured indebtedness,

                                 - will rank senior in right of payment to all
                                   of our subordinated unsecured indebtedness;

                                 - will rank junior to our secured obligations,
                                   with respect to the assets which are pledged,
                                   and will rank equal to such obligations to
                                   the extent that the pledged assets do not
                                   satisfy the secured obligations; and

                                        4
<PAGE>   8

                                 - will rank junior to all existing and future
                                   indebtedness and other liabilities of our
                                   subsidiaries. On February 29, 2000, the
                                   aggregate indebtedness and liabilities of our
                                   subsidiaries was approximately $3.3 billion.
                                   The aggregate indebtedness and liabilities of
                                   Aerial Communications, Inc., which we expect
                                   to become a subsidiary of ours, was $411.8
                                   million on December 31, 1999.

Optional Redemption...........   We have the option to redeem our notes, in
                                 whole or in part, at any time on or after
                                 November 15, 2004, at the redemption prices set
                                 forth in this prospectus under "Description of
                                 the Notes -- Optional Redemption" plus accrued
                                 and unpaid interest, if any, to the date of
                                 redemption.

                                 In addition, on or before November 15, 2002, we
                                 have the option to apply proceeds from
                                 qualifying equity sales to redeem up to 35% of
                                 the originally issued principal amount of the
                                 senior notes at a price of 110.375% of the
                                 principal amount thereof plus accrued and
                                 unpaid interest to the date of redemption
                                 provided that after the redemption at least 65%
                                 of the originally issued aggregate principal
                                 amount of the senior notes remains outstanding.

Sinking Fund..................   The notes will not be entitled to any sinking
                                 fund.

Change of Control.............   Upon a change of control and a ratings decline
                                 or upon asset dispositions described in the
                                 indenture, we will be required to offer to
                                 purchase the notes for a purchase price in cash
                                 equal to 101% of the accreted value or
                                 principal amount at maturity of the notes, as
                                 applicable, plus accrued and unpaid interest.
                                 However, we will not be able to repurchase
                                 notes without obtaining written consents from
                                 or repaying the lenders under our credit
                                 facility.

Restrictive Covenants.........   The indenture under which we will issue the
                                 notes restrict our (and our subsidiaries')
                                 ability to do the following:

                                 - incur additional indebtedness;

                                 - make payments in respect of securities that
                                   are junior to our notes;

                                 - allow restrictions on our subsidiaries'
                                   ability to make payments to us;

                                 - cause our subsidiaries to guarantee our debt;

                                 - enter into transactions with affiliates;

                                 - issue capital stock of our subsidiaries;

                                        5
<PAGE>   9

                                 - grant liens on our property;

                                 - enter into sale and leaseback transactions;

                                 - dispose of significant assets; and

                                 - engage in consolidations, mergers and asset
                                   transfers.

Settlement and Book-Entry
Form..........................   Our notes will be evidenced by a note in global
                                 form which will be deposited with a custodian
                                 for, and registered in the name of the nominee
                                 of, The Depository Trust Company ("DTC") in New
                                 York, New York.

                                  RISK FACTORS

     Before agreeing to accept our new notes, you should carefully consider the
risks described below, in addition to the other information presented in this
prospectus or incorporated by reference into this prospectus. If any of the
following risks actually occur, they could seriously harm our business,
financial condition or results of operations. In such case, you may lose all or
part of your investment.

THE NOTES ARE THE OBLIGATIONS OF A HOLDING COMPANY WHICH HAS NO OPERATIONS AND
DEPENDS ON SUBSIDIARIES FOR CASH, AND ITS SUBSIDIARIES MAY BE LIMITED IN THEIR
ABILITY TO MAKE FUNDS AVAILABLE

     Tendering Omnipoint note holders will be exchanging a note that is not
structurally subordinate to the general obligations of Omnipoint for one that
is. As a holding company, we will not hold substantial assets other than our
direct or indirect investments in and advances to our operating subsidiaries.
Consequently, our subsidiaries conduct all of our consolidated operations and
own substantially all of our consolidated assets. Our cash flow and our ability
to meet our debt service obligations on the notes will depend upon the cash flow
of our subsidiaries and the payment of funds by the subsidiaries to us in the
form of loans, equity distributions or otherwise. Our subsidiaries are not
obligated to make funds available to us for payment on the notes or otherwise.
In addition, our subsidiaries' ability to make any loans or distributions to us
will depend on their earnings, the terms of their indebtedness, business and tax
considerations and legal restrictions.

     Because of the structure described above, the notes will be subordinate to
all borrowings and liabilities of our subsidiaries. Our lenders under credit
facility and all creditors of any of our subsidiaries will have the right to be
paid before you from any cash received or held by our subsidiaries. In the event
of bankruptcy, liquidation or dissolution of a subsidiary, following payment by
the subsidiary of its liabilities, it may not have sufficient assets remaining
to make any payments to us as a shareholder or otherwise. As of February 29,
2000, the total outstanding indebtedness and liabilities of our subsidiaries was
approximately $3.3 billion. The aggregate liabilities and indebtedness of Aeriel
Communications, Inc., which we expect to become our subsidiary, was $411.8
million on December 31, 1999.

A TENDERING OMNIPOINT NOTEHOLDER WILL RECOGNIZE GAIN OR LOSS U.S. FEDERAL INCOME
TAX PURPOSES


     A tendering Omnipoint note holder will recognize gain or loss for U.S.
federal income for tax purposes generally equal to the difference between the
holder's basis in the outstanding Omnipoint notes and the issue price of our
notes. The issue price of our notes should be their fair market value on the
date of the exchange, assuming that the notes are "publicly traded" as defined
in applicable Treasury Regulations.


WE FACE INTENSE COMPETITION FROM OTHER WIRELESS SERVICE PROVIDERS, WHICH COULD
ADVERSELY AFFECT OUR ABILITY TO GROW OUR SUBSCRIBER BASE AND REVENUES

     We compete with providers of PCS, cellular and other wireless
communications services. Under the current rules of the FCC, up to seven PCS
licensees and two cellular licensees may operate in each geographic area.
Proposed or future rules may increase the number of licenses available. With so
many companies targeting many of the same customers, competition is intense. We
compete against AT&T Wireless Services, Inc., Bell Atlantic Mobile Systems,
Nextel Communications, Inc., SBC Communications, Sprint Corp. (PCS Group), US
West Wireless LLC and Vodafone AirTouch Cellular Communications, Inc., among
others. Many of these competitors have substantially greater financial resources
than we do, and several operate in multiple segments of the industry. AT&T
Wireless, Nextel and Sprint PCS operate substantially nationwide networks and
Bell Atlantic Mobile

                                        7
<PAGE>   11

'Systems and Vodafone AirTouch, among others, through joint ventures and
affiliation arrangements, operate or plan to operate substantially nationwide
wireless systems throughout the continental United States. As a result of such
competition, we cannot assure you that we will be able to successfully attract
and retain customers and increase our subscriber base and revenues.

WE HAVE A LIMITED OPERATING HISTORY WITH SUBSTANTIAL OPERATING LOSSES AND
NEGATIVE CASH FLOW, AND WE MAY NOT BECOME PROFITABLE

     We were incorporated in June 1999 and have not conducted any activities
other than in connection with our organization and the transactions through
which we became the parent company of VS Washington, Inc. (formerly VoiceStream
Wireless Corporation, a Washington corporation) and Omnipoint on February 25,
2000. On a pro forma basis giving retroactive effect to the Omnipoint merger, we
sustained operating losses of approximately $1.0 billion in 1999, and also on a
pro forma basis as of December 31, 1999, we had an accumulated deficit of $1.1
billion and equity, net of accumulated deficit, of $3.2 billion. We expect
Aerial Communications, Inc. to become our subsidiary. Aerial sustained operating
losses of approximately $210.0 million in 1999. As of December 31, 1999, Aerial
had an accumulated deficit of $800.2 million and equity, net of accumulated
deficit, of $410.6 million. We expect to incur significant operating losses and
to generate negative cash flow from operating activities during the next several
years while we continue to develop and construct our systems and grow our
subscriber base. We cannot assure you that we will achieve or sustain
profitability or positive cash flow from operating activities in the future or
that we will generate sufficient cash flow to service current or future debt
requirements.

OUR SUBSTANTIAL DEBT LIMITS OUR ABILITY TO BORROW ADDITIONAL FUNDS TO FINANCE
OUR GROWTH, CREATES FINANCIAL AND OPERATING RISKS, AND MAKES US VULNERABLE TO
INCREASES IN INTEREST RATES

     We are highly leveraged and subject to strict financial limitations because
we have incurred a significant amount of debt in building our systems and
subscriber bases. Our total debt on February 29, 2000 was approximately $4.8
billion. In addition, as of December 31, 1999, Aerial's total debt was
approximately $411.8 million. Our level of debt, and the incurrence of
additional debt in the future, could have important consequences to you. For
example, it could:

     - make it more difficult for us to satisfy our obligations with respect to
       our existing indebtedness;

     - require us to dedicate a substantial portion of our cash flow from
       operations to paying principal and interest on our debt, thereby reducing
       the availability of our cash flow to fund working capital, capital
       expenditures, acquisitions of additional systems and other general
       corporate requirements;

     - limit our flexibility in reacting to changes in our business and the
       wireless industry generally;

     - limit our ability to borrow additional funds due to applicable financial
       and restrictive covenants in such indebtedness; and

     - make us more vulnerable to increases in prevailing interest rates because
       certain of our borrowings are and will continue to be at variable rates
       of interest.

                                        8
<PAGE>   12

IF WE CANNOT RAISE SUFFICIENT FUNDS TO MEET OUR SIGNIFICANT FUTURE CAPITAL
REQUIREMENTS, WE WILL NOT BE ABLE TO COMPETE EFFECTIVELY IN THE WIRELESS
COMMUNICATIONS INDUSTRY

     Our systems and the systems of joint ventures in which we are an investor
are not completely built out and do not have nationwide coverage. The build-out
of these systems and the development of new systems will require significant
capital expenditures. We plan to meet our additional capital needs for the
build-out of our systems with the proceeds from credit facilities and other
borrowings, the proceeds from sales of additional debt securities, the sale or
issuance of equity securities, financing arrangements with vendors and through
joint ventures. We cannot guarantee that we will be able to raise sufficient
additional capital on commercially reasonable terms or at all. If we do not
raise sufficient funds, we may delay or abandon some or all of our planned
build-out or expenditures, which could materially limit our ability to compete
in the wireless communications industry.

THERE IS A RISK THAT OUR EXPANSION WILL BE CONSTRAINED BECAUSE OUR ABILITY TO
EXPAND AND PROVIDE SERVICE NATIONALLY IS LIMITED BY OUR ABILITY TO OBTAIN FCC
LICENSES

     Even combined with Aerial, we will not have licenses covering the entire
United States. Our ability to expand is limited to those markets where we have
obtained or can obtain licenses with sufficient spectrum to provide PCS service,
or where we can economically become resellers of service. Because there are a
limited number of licenses available, and because resale agreements require
mutual consent of the incumbent PCS license holders, there is a risk that we may
not be able to obtain the licenses we need for expansion.

WE ARE AT RISK OF LOSING COVERAGE IN CERTAIN MARKETS BECAUSE WE HAVE ENTERED
INTO JOINT VENTURES THAT WE DO NOT CONTROL IN AN ATTEMPT TO EXPAND INTO THOSE
MARKETS

     When implementing the PCS licensing scheme in the United States, the FCC
adopted rules that granted a narrow category of entities the right to bid for
and own C and F Block licenses. We do not qualify to obtain C and F Block
licenses. In order to continue to expand our system, we obtained 49.9% minority
ownership interests in four joint ventures controlled by Cook Inlet Region,
Inc., each of which qualified to hold licenses that we could not directly hold.
In all markets where the joint ventures operate, including the Philadelphia,
Chicago and Dallas markets, we are at risk because Cook Inlet is in control and
can choose to operate independently of us. If the joint venture entities
determine to operate independently our ability to compete on a national scale
may be adversely affected.

OUR CURRENT AND FUTURE INVESTMENT IN EACH CURRENT JOINT VENTURE IS AT RISK
BECAUSE WE HAVE LIMITED INVESTOR PROTECTIONS, AND WE MAY BE REQUIRED TO RELY ON
ADDITIONAL JOINT VENTURES FOR FURTHER EXPANSION

     We do not control, and maintain only limited investor protection rights, in
the four joint venture entities controlled by Cook Inlet Region, Inc. We have
substantial financial commitments to these joint ventures, which must rely on
corresponding financial commitments from Cook Inlet. Also, many of the systems
owned by these joint venture entities have not been built out and the joint
ventures will have substantial capital needs in connection with such build-outs.
We cannot guarantee that these joint venture entities will be able to raise
sufficient capital, whether through bank borrowings or otherwise, to complete
the build-out of their systems. Similarly, due to the licensing restrictions
discussed above, and because of the scarcity of available PCS licenses covering
United States urban markets, we may be required to rely on similar joint
ventures that we do not control for expansion into new markets. We cannot assure
you that we will be able to find acceptable joint venture partners. In the event
that we do find acceptable joint venture partners, due to our lack of control

                                        9
<PAGE>   13

over these joint ventures, we cannot assure you that they will operate in a
manner that increases the value of our business.

WE WILL BE SUBJECT TO EXTENSIVE GOVERNMENT REGULATION, ANY CHANGE IN WHICH COULD
AFFECT OUR BUILD-OUT PLAN OR FINANCIAL PERFORMANCE

     The licensing, construction, operation, sale and interconnection
arrangements of wireless telecommunications systems are regulated to varying
degrees by the FCC and, depending on the jurisdiction, also may be regulated by
state and local governmental bodies. There can be no assurance that either the
FCC or such state and local agencies will not adopt regulations or take other
actions that would adversely affect our business. We cannot assure you that we
will be able to obtain and retain all necessary governmental authorizations and
permits. Failure to do so could negatively affect our existing operations and
delay or prevent proposed operations.

THE FCC AND OTHER REGULATORY AGENCIES MUST APPROVE THE REORGANIZATION WITH
AERIAL AND COULD DELAY OR REFUSE TO APPROVE THE REORGANIZATION OR IMPOSE
CONDITIONS THAT COULD ADVERSELY AFFECT OUR BUSINESS OR FINANCIAL CONDITION

     The Communications Act and FCC rules require the FCC's prior approval of
the transfer of control of Aerial's PCS licenses to us. Completion of the
transactions through which we will become the parent company of Aerial are
conditioned, among other factors, upon grants of the requisite FCC consents
becoming final. A "final" FCC order is one that has not been stayed and is no
longer subject to review by the FCC or the courts because the statutory period
for seeking such review has expired without any request for review or stay
pending. Following the FCC's grant of consent, we cannot assure you that there
will not be any post-grant challenges by private parties or actions by the FCC
or the courts that would delay or prevent finality. Though our board of
directors and Aerial's board of directors, in the exercise of their business
judgment, without seeking stockholder approval, may waive finality as a
condition of closing, we cannot assure you that they will do so. We cannot
assure you that the FCC will grant the applications, that the FCC will grant the
applications without conditions, or that there will be no delay caused by the
filing of a challenge to the transfer and assignment applications. Conditions
imposed on any licenses granted or delays in granting of the licenses could
impair the value of the licenses and reduce the value of our stock, and could
lead to our inability to obtain financing necessary for our growth. If we are
denied a license in a market we will not be able to operate in that market
unless we maintain another license or acquire a new license for that market.

THERE IS A RISK THAT THE JOINT VENTURE ENTITIES IN WHICH WE HOLD INTERESTS COULD
LOSE LICENSES AS A RESULT OF COURT PROCEEDINGS

     All C Block licenses held by Cook Inlet entities could be affected by U.S.
Airwaves, Inc. v FCC, which is pending in the U.S. Court of Appeals for the D.C.
Circuit. U.S. Airwaves is seeking judicial review of two orders in the FCC's
rulemaking proceeding on payment financing for PCS licenses. Since these orders
enabled initial C Block licensees to return licenses or modify the conditions of
payment, there is a remote threat that if the orders are reversed, affected
licenses could be returned to the Commission for reauction. Additionally, 25
licenses held by Cook Inlet joint ventures were issued subject to the outcome of
the bankruptcy proceeding of the original licensee, a subsidiary of Pocket
Communications Inc., which was conditionally granted 43 C Block licenses in
1996. Pursuant to an FCC order, the bankruptcy debtors elected to relinquish
certain licenses, which subsequently were reauctioned, and the bankruptcy court
issued an order making the election effective. A secured creditor of the debtors
appealed and, as a result, the bankruptcy court stayed its order. Because the
appeal is still pending there is uncertainty as to the referenced C Block
licenses of the Cook Inlet

                                       10
<PAGE>   14

entities. The district court could order the return of these licenses to the
jurisdiction of the bankruptcy court. In the event that these licenses are so
returned, it is unlikely that the Cook Inlet entities will be able to recoup any
or all of the costs incurred by them in connection with the construction and
development of systems related to such licenses. Loss of any license by any Cook
Inlet entity will reduce or eliminate our ability to own interests in markets
where the licenses are lost, thereby reducing our ability to compete with other
national competitors.

THERE IS A RISK THAT WE WILL LOSE LICENSES IF THEY ARE NOT RENEWED BY THE FCC

     FCC licenses to provide PCS services are subject to renewal requirements
and to revocation at any time for cause. Our licenses begin to expire in 2004.
We cannot assure you that the FCC will renew our licenses. If we lose a license
for a market we will not be able to operate in that market unless we maintain
another license or acquire a new license for that market.

THERE IS A RISK THAT OUR SUBSIDIARY MAY HAVE TO MAKE SUBSTANTIAL TAX INDEMNITY
PAYMENTS TO WESTERN WIRELESS CORPORATION


     In a spin-off transaction effected on May 3, 1999, Western Wireless
distributed its entire 80.1% interest in VS Washington's common stock to its
stockholders. Western Wireless will recognize gain as a result of the spin-off
if the spin-off is considered to be part of a "prohibited plan," which is a plan
or series of related transactions pursuant to which one or more persons acquire,
directly or indirectly, 50% or more of VS Washington's common stock. This is a
risk because VS Washington agreed to indemnify Western Wireless on an after-tax
basis for any taxes, penalties, and interest and various other expenses incurred
by Western Wireless if it is required to recognize such gain. Under the Internal
Revenue Code, the reorganization and the related transactions through which we
became the parent of VS Washington and Omnipoint, combined with Hutchison
Telecommunications (PCS) USA's acquisition of VS Washington stock within two
years prior to the spin-off, will give rise to a rebuttable presumption that the
spin-off was effected pursuant to a prohibited plan and, thus, that Western
Wireless recognized gain as a result of the spin-off.


     The precise standard that must be met by VS Washington to rebut the
presumption is not presently clear. Thus, counsel is unable to opine on the
issue and there is a risk that VS Washington will be unable to rebut the
presumption. In addition, no matter what the standard is for rebutting the
presumption, there is a risk that the IRS would not agree that any facts that
would be presented by VS Washington would establish that the spin-off was not
effected pursuant to a prohibited plan, and there is a risk that a court would
concur with such an IRS position. As a result, Western Wireless would be
required to recognize gain upon the spin-off and VS Washington would be required
to indemnify Western Wireless on an after-tax basis for its resulting taxes,
penalties, if any, and interest, and various other expenses. We estimate that
the range of VS Washington's indemnity exposure, not including penalties and
interest, is from zero to $400 million. Thus, if it is required to make an
indemnity payment to Western Wireless, it could have a material adverse effect
on us.

CONCERNS OVER RADIO FREQUENCY EMISSIONS OR OTHER HEALTH AND SAFETY RISKS MAY
DISCOURAGE USE OF WIRELESS SERVICES AND ADVERSELY EFFECT OUR BUSINESS

     Media reports have suggested that some radio frequency emissions from
wireless handsets may raise various health concerns, including cancer, and may
interfere with various electronic medical devices, including hearing aids and
pacemakers. Concerns over radio frequency emissions may discourage the use of
wireless handsets, which would adversely affect our business. Negative findings
of studies concerning health and safety risks of wireless handsets could have an
adverse effect on the wireless industry, our business, or the use of GSM
technology. Such findings could lead to

governmental regulations that may have an adverse effect on our business.
Several states have proposed or enacted legislation which would limit or
prohibit the use and/or possession of a mobile telephone while driving an
automobile. If states adopt and strictly enforce such legislation, it may have
an adverse effect on our business.

WE MAY BE UNABLE TO PURCHASE OUR NOTES UPON A CHANGE OF CONTROL

     Upon the occurrence of a change of control, you, along with all other
holders of our notes, may require us to repurchase all or a portion of our notes
at 101% of the principal amount (or accreted value in the case of senior
discount notes) of the notes, together with accrued and unpaid interest to the
date of repurchase. If a change of control were to occur, we may not have the
financial resources to repay the notes, our credit facilities and any other
indebtedness that would become payable upon the occurrence of such change of
control. The covenant requiring us to repurchase the notes will, unless consents
of lenders under our credit agreement are obtained, require us to repay all
indebtedness then outstanding under our credit agreement in the event of a
change of control. There can be no assurance that we will have sufficient funds
available at the time of any change of control to make any debt payment
(including repurchase of our notes) required by this covenant. See "Description
of our new Notes -- Repurchase of Notes upon a Change of Control:

                               THE EXCHANGE OFFER


     Subject to the terms and conditions in this prospectus and in the
accompanying Letter of Transmittal, we will issue $1048 in principal amount of
our 10 3/8% senior notes due 2009 in exchange for each $1000 in principal amount
of Omnipoint's outstanding 14% Senior Notes due 2003 that are properly tendered
on or before the expiration of the offer. The expiration of the offer is 5:00
p.m., New York City time, on June 9, 2000 unless we extend it.


     We may, at any time or from time to time, extend the expiration date, by
giving oral or written notice of such extension in the manner described below.
Omnipoint notes may be accepted for exchange at any time after they are
tendered. Any outstanding notes that we do not accept for exchange for any
reason will be returned to you without cost as promptly as practicable after the
expiration or termination of the exchange offer.

     This prospectus, together with the Letter of Transmittal, is first being
sent on or about the date of this prospectus to all holders known to us of
Omnipoint outstanding notes that are the subject of the offer described herein.
Our obligation to accept outstanding notes for exchange or purchase is subject
to certain conditions as set forth below under "-- Certain Conditions to the
Exchange Offer."

     Outstanding notes tendered in the exchange offer must be in denominations
of principal amounts of $1,000 and any integral multiples thereof.

     Our notes that are issued in exchange for the Omnipoint notes will be
deemed to have accrued interest since November 9, 1999 unless they are issued
after May 15, 2000, in which case they will be deemed to have accrued interest
from that date. Tendering Omnipoint note holders will be required to pay us the
amount of unpaid interest that is deemed to have accrued on our notes at the
time of their issuance, and we will pay the tendering note holders the amount of
accrued and unpaid interest on their Omnipoint notes to the same date.

Procedures for Tendering Outstanding Notes

     In all cases, issuance of our new notes for outstanding Omnipoint notes
that are accepted for exchange or payment will be made only after timely receipt
by the exchange agent of:

          (i) certificates for such outstanding notes or a timely book-entry
     confirmation of such outstanding notes into the exchange agent's account at
     the book-entry transfer facility;

          (ii) a properly completed and duly executed Letter of Transmittal or
     an agent's message in lieu thereof; and

          (iii) all other required documents.

     The term "agent's message" means a message, transmitted by the book-entry
transfer facility to and received by the exchange agent and depository. It forms
a part of a book-entry confirmation, which states that the book-entry transfer
facility has received an express acknowledgment from the tendering participant
stating that the participant has received and agrees to be bound by the Letter
of Transmittal and that we may enforce the Letter of Transmittal against that
participant. THE METHOD OF DELIVERY OF THE OUTSTANDING NOTES, THE LETTER OF
TRANSMITTAL AND ALL OTHER REQUIRED DOCUMENTS IS AT THE ELECTION AND RISK OF THE
HOLDERS. IF DELIVERY MADE IS BY MAIL, IT IS RECOMMENDED THAT REGISTERED MAIL,
PROPERLY INSURED, WITH RETURN RECEIPT REQUESTED, BE USED. IN ALL CASES,
SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY DELIVERY. DELIVERY OF
DOCUMENTS TO DTC IN ACCORDANCE WITH

                                       13

ITS PROCEDURES DOES NOT CONSTITUTE DELIVERY TO THE EXCHANGE AGENT. NO DOCUMENTS
SHOULD BE SENT TO US.

     Signatures on a Letter of Transmittal or a notice of withdrawal, as the
case may be, must be guaranteed by one of the following eligible institutions:

     - a member firm of a registered national securities exchange or of the
       National Association of Securities Dealers, Inc.;

     - a commercial bank; or

     - a trust company having an office or correspondent in the United States;

unless the notes tendered are tendered:

          (i) by a registered holder of the notes who has not completed the box
     entitled "Special Issuance Instructions" or "Special Delivery Instructions"
     on the Letter of Transmittal; or

          (ii) for the account of an eligible institution.

     If tendered notes are registered to a person who did not sign the Letter of
Transmittal, they must be endorsed by, or be accompanied by a written transfer
or exchange, duly executed by the registered holder with the signature
guaranteed by an eligible institution and appropriate powers of attorney, signed
exactly as the name of the registered holder appears on the outstanding notes.
All questions of satisfaction of the form of the writing will be determined by
us in our sole discretion.

     If the Letter of Transmittal or any outstanding notes or powers of attorney
are signed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in a fiduciary or representative
capacity, such persons should so indicate when signing, and unless waived by us,
submit evidence satisfactory to us of their authority to so act with the letter
of transmittal.

     We will determine all questions as to the validity, form, eligibility
(including time of receipt), acceptance and withdrawal of the tendered
outstanding notes. Our determination will be final and binding. We reserve the
absolute right to reject any and all tenders of any particular outstanding notes
not properly tendered or not to accept any particular outstanding notes if our
acceptance would, in our opinion or in the opinion of our counsel, be unlawful.
We also reserve the absolute right to waive any defects or irregularities or
conditions of the exchange offers as to any particular outstanding notes.

     Our interpretation of the terms and conditions of the exchange offers
(including the instructions in the Letter of Transmittal) will be final and
binding on all parties. Unless waived, any defects or irregularities in
connection with tenders of outstanding notes must be cured within a time period
we determine. Neither we, the exchange agent nor any other person is under any
duty to give notification of defects or irregularities with respect to tenders
of outstanding notes nor shall any of them incur any liability for failure to
give such notification. Any outstanding notes will not be considered to have
been properly tendered until such defects or irregularities have been cured or
waived. Any outstanding notes received by the exchange agent that have not been
properly tendered and as to which the defects or irregularities have not been
cured or waived will be returned without cost by the exchange agent and
depository to the tendering holder unless otherwise provided in the Letter of
Transmittal, as soon as practicable following the expiration date.

                                       14
<PAGE>   18

     In addition, we reserve the right in our sole discretion to:

          (i) purchase or make offers for any outstanding notes that remain
     outstanding subsequent to the expiration date, or, to terminate the
     exchange offers; and

          (ii) to the extent permitted by applicable law, purchase outstanding
     notes in the open market, in privately negotiated transactions or otherwise
     on terms different from the terms of the exchange offers.

Acceptance of Outstanding Notes for Exchange; Delivery of New Notes

     Upon satisfaction or waiver of the conditions to the exchange offers, we
may accept all outstanding notes properly tendered at any time after their
tender and will issue the new notes in exchange. See "-- Certain Conditions to
the Exchange Offer."

     We will be deemed to have accepted properly tendered outstanding notes for
exchange if or when we give oral or written notice of acceptance to the exchange
agent, with written confirmation of any oral notice to follow promptly.

     If any tendered notes are not accepted for any reason or if outstanding
notes are submitted for a greater principal amount than the holder desired to
exchange, the unaccepted or non-exchanged outstanding notes will be returned
without expense to the tendering holder (or, in the case of outstanding notes
tendered by book-entry transfer into the exchange agent's account at the
book-entry transfer facility pursuant to the book-entry procedures described
below, the non-exchanged outstanding notes will be credited to an account
maintained with such book-entry transfer facility) as promptly as practicable
after the expiration or termination of the exchange offer.

Book-Entry Transfer

     The exchange agent and depository will make a request to establish an
account with respect to the outstanding notes at the book-entry transfer
facility for purposes of the exchange offer within two business days after the
date of this prospectus. Any financial institution that is a participant in the
book-entry transfer facility's systems may make book-entry delivery of
outstanding notes by causing the book-entry transfer facility to transfer the
outstanding notes into the Exchange Agent's account at the book-entry transfer
facility in accordance with the facility's procedures. However, while delivery
of outstanding notes may be effected through book-entry transfer at the
book-entry transfer facility, the Letter of Transmittal (or a facsimile thereof
or an agent's message in lieu thereof), with any required signature guarantees
and any other required documents, must still be transmitted to and received by
the exchange agent at one of the addresses set forth below, under "-- Exchange
Agent" on or before the expiration date or the guaranteed delivery procedures
described below must be complied with.

Guaranteed Delivery Procedures

          (i) the outstanding notes are not immediately available; or

     required documents cannot be delivered to the exchange agent and depository
     on a timely basis; or

          (iii) book-entry transfer of the outstanding note cannot be completed
     on a timely basis;

          transfer, or a book-entry confirmation, as the case may be, together
          with a properly completed and duly executed Letter of Transmittal (or
          a facsimile thereof or an agent's message in lieu thereof) with any
          required signature guarantees, and all other documents required by the
          Letter of Transmittal are received by the exchange agent within three
          New York Stock Exchange trading days after the date of execution of
          the Notice of Guaranteed Delivery; and

        - the certificates for all physically tendered outstanding notes, in
          proper form for transfer, or a book-entry confirmation, as the case
          may be, together with a properly completed and duly executed Letter of
          transmittal (or a facsimile thereof or an agent's message in lieu
          thereof), with any required signature guarantees and any other
          documents required by the Letter of Transmittal, that will be
          deposited by the eligible institution with the exchange agent within
          three New York Stock Exchange trading days after the date of execution
          of the Notice of Guaranteed Delivery.

Withdrawal Rights

     Except as otherwise provided herein, tendered notes may be withdrawn at any
time prior to their acceptance for exchange.

     To withdraw a tendered note, a written notice of withdrawal must be
received by the exchange agent at its address set forth herein before the note
has been accepted for exchange. Any such notice of withdrawal must:

          (i) specify the name of the depositor having tendered the outstanding
     note to be withdrawn;

          (ii) include a statement that the depositor is withdrawing its
     election to have outstanding note exchanged or purchased, and identify the
     outstanding note to be withdrawn (including the certificate number or
     numbers and principal amount of the outstanding note); and

          (iii) where a certificate for the outstanding note has been
     transmitted, specify the name in which such outstanding note is registered,
     if different from that of the withdrawing holder.

     If a certificate for the tendered note has been delivered or otherwise
identified to the exchange agent, then, prior to the release of such
certificates the withdrawing holder must also submit:

          (i) the serial number of the particular certificate to be withdrawn;
     and

          (ii) signed notice of withdrawal with signatures guaranteed by an
     eligible institution unless the holder is an eligible institution.

                                       16
<PAGE>   20

     If outstanding notes have been tendered pursuant to the procedure for
book-entry transfer described above, any notice of withdrawal must specify the
name and number of the account at the book-entry transfer facility to be
credited with the withdrawn outstanding notes and otherwise comply with the
procedures of the facility.

     We will determine all questions as to the validity, form and eligibility
(including time or receipt) for such withdrawal notices. Our determination shall
be final and binding on all parties.

     Any outstanding notes so withdrawn will be considered not to have been
validly tendered for purposes of the exchange offer and no new notes will be
issued with respect thereto unless the outstanding notes so withdrawn are
validly retendered.

Certain Conditions to the Exchange Offers

     The exchange offer is subject only to the condition that it does not
violate applicable law or any applicable interpretation of the staff of the
commission. We cannot assure you that this condition will be satisfied.

     If we determine that we must terminate the exchange offer, as set forth
above, we may:

     - refuse to accept any outstanding notes and return any outstanding notes
       that have been tendered;

     - extend the exchange and cash tender offers and retain all outstanding
       notes tendered prior to the expiration date; or

     - waive a termination event with respect to the exchange and cash tender
       offer and accept all properly tendered outstanding notes that have not
       been withdrawn.

     If the waiver would constitute a material change in the exchange offer, we
will disclose that change through a supplement to this prospectus that will be
distributed to each registered holder of outstanding notes. In addition, we will
extend the exchange offer for a period of five to ten business days, depending
upon the significance of the waiver and the manner of disclosure to the
registered holders of the outstanding notes, if the exchange offer would
otherwise expire during such period.

                                  THE COMPANY

     We are a leading provider of personal communications services through
technology based on the wireless communications standard known as Global System
for Mobile Communications, commonly known as GSM. Our licenses, together with
licenses held by joint ventures in which we are an investor, cover 17 of the 25
largest markets in the continental United States and over 193 million persons.
Our company was incorporated in June 1999 as a Delaware corporation to act as
the parent company for the business combination of VoiceStream Wireless
Corporation, a Washington corporation ("VoiceStream Washington," now known as VS
Washington, Inc.), Omnipoint and Aerial Communications, Inc., a Delaware
corporation. On February 25, we became the parent company of both VS Washington
and Omnipoint. We are now the successor registrant of VoiceStream Washington.
Our business currently consists of the combined businesses of VS Washington and
Omnipoint and their subsidiaries. The shareholders of Aerial have approved
transactions through which we will also become the parent of Aerial. There can
be no assurance that

                                       18
<PAGE>   22

the Aerial transactions will be completed. Upon completion of those
transactions, we will add the current business of Aerial to our business. The
combined businesses will have licenses that cover 23 of the 25 largest markets
in the continental United States and over 222 million persons.

     We are organized as a Delaware corporation with our principal executive
offices located at 3650 131st Avenue S.E., Bellevue, WA 98006. Our telephone

                          DESCRIPTION OF OUR NEW NOTES

GENERAL

     You can find the definitions of certain capitalized terms used in the
following summary under the subheading "-- Certain Definitions".

     We will issue the 10 3/8% Senior Notes due 2009 under an indenture, between
us and Harris Trust Company of California, as trustee. The terms of the notes
include those stated in the indenture and those made part of the indenture by
reference to the Trust Indenture Act of 1939, as amended.

     The following is a summary of the material provisions of the indenture. It
does not restate the indenture in its entirety. We urge you to read the
indenture, because it, and not this description, defines your rights as holders
of notes. Copies of the indenture are available upon request from the trustee.

     Notwithstanding anything herein to the contrary, no provisions of the
indenture shall be violated as a result of the consummation of any of the
transactions contemplated by the Aerial reorganization, nor will the provisions
of the indenture with respect to change of control events or requiring certain
actions with respect to proceeds for Asset Dispositions be applicable to any
such transaction.

BRIEF DESCRIPTION OF THE NOTES

     The notes will:

     - be general obligations of ours;

     - rank equal in right of payment with all of our other senior unsecured
       Indebtedness, including the Senior Discount Notes;

     - rank senior in right of payment to all of our subordinated unsecured
       Indebtedness;

     - rank junior to secured obligations of ours, with respect to the assets
       which are secured, and will rank equal to such obligations to the extent
       that the secured assets do not satisfy the secured obligations;

     - rank junior to all existing and future Indebtedness and other liabilities
       of our subsidiaries;

     - be deemed to have accrued interest from November 9, 1999 (or May 15,
       2000, if they are issued after that date);

     - accrue interest at a rate of 10 3/8%, which is payable semi-annually on
       May 15 and November 15 commencing May 15, 2000 (unless the notes are
       issued after that date in which case the first interest payment date will
       be November 15, 2000); and

     - mature on November 15, 2009.

     We will offer to repurchase notes under circumstances described in the
indenture upon:

     - a Change of Control Triggering Event; or

     - an Asset Disposition by us or any of our Restricted Subsidiaries.

     We may repurchase all notes upon a Change of Control Triggering Event.

     The indenture governing the notes also contain the following covenants:

     - restrictions on incurrence of consolidated indebtedness;

     - restrictions on Restricted Payments;

     - restrictions on dividend and other payment restrictions affecting
       Subsidiaries;

     - limitation on issuances and sales of Capital Stock of Restricted
       Subsidiaries;

     - restrictions on transactions with Affiliates;

                                       20
<PAGE>   24

     - restrictions on Liens;

     - restrictions on sale and leaseback transactions;

     - undertaking to deliver reports; and

     - restrictions on merger, consolidation or sales of assets.

     Our operations are conducted through Subsidiaries and, therefore, depend on
the cash flow of Subsidiaries to meet our obligations, including obligations
under the notes. Our Subsidiaries, including Omnipoint and its Subsidiaries will
not be guarantors of the notes and the notes will be structurally subordinated
to all indebtedness, including all borrowings, of those Subsidiaries. Our right
to receive assets of any Subsidiaries upon the liquidation or reorganization of
those Subsidiaries (and the consequent right of the holders of the notes to
participate in those assets) will be legally subordinated to the claims of that
Subsidiary's creditors, except to the extent that we are recognized as a
creditor of that Subsidiary. If we are recognized as a creditor of a Subsidiary,
our claims would still be subordinate in right of payment to any security in the
assets of that Subsidiary and any indebtedness of that Subsidiary senior to that
held by us. See "Risk Factors -- The notes are the obligations of a holding
company which has no operations and depends on subsidiaries for cash, and its
subsidiaries may be limited in their ability to make funds available".

     As of the date of the indenture, all of our Subsidiaries will be Restricted
Subsidiaries and assuming completion of the Aerial reorganization, Aerial and
all of its Subsidiaries will be Restricted Subsidiaries. However, under certain
circumstances, we will each be able to designate current or future Subsidiaries
as Unrestricted Subsidiaries. Unrestricted Subsidiaries will not be subject to
many of the restrictive covenants set forth in the indenture.

PRINCIPAL, MATURITY AND INTEREST

     On November 9, 1999, we issued notes with an aggregate principal amount of
up to $1.1 billion. The indenture governing those notes allows us to issue
additional notes in principal amount of up to $1.1 billion. The notes being
offered in exchange for the Omnipoint notes will be an additional issuance under
that indenture. The issuance of any of additional notes is subject to our
ability to incur Indebtedness under the covenant described under
"-- Covenants -- Limitation on Consolidated Indebtedness" and similar
restrictions in the instruments governing our other Indebtedness. Any such
additional notes will be treated as part of the same class and series as the
notes originally issued for purposes of voting under the indenture.

     Interest on the notes will accrue at the rate of 10 3/8% per annum and will
be payable in U.S. dollars semiannually in arrears on May 15 and November 15. We
will make each interest payment to holders of record on the immediately
preceding May 1 and November 1.

     Cash interest will accrue on the notes from the most recent date to which
interest has been paid or, if no interest has been paid, from November 9, 1999.
Interest will be computed on the basis of a 360-day year consisting of twelve
30-day months.

METHOD OF RECEIVING PAYMENTS ON THE NOTES

     If a holder has given wire transfer instructions to us, we will make all
payments of principal, premium and interest, if any, on that holder's notes in
accordance with those instructions. All other payments on the notes will be made
at the office or agency of the paying agent and registrar for the notes within
the City and State of New York unless we elect to make interest payments by
check mailed to the holders at their principal address set forth in the register
of holders.

                                       21
<PAGE>   25

PAYING AGENT AND REGISTRAR FOR THE NOTES

     The trustee under the indenture will initially act as the paying agent and
registrar for the notes. We may change the paying agent or registrar under the
indentures without prior notice to the holders of the notes, and we or any of
our Subsidiaries may act as paying agent or registrar under the indenture.

OPTIONAL REDEMPTION

     Until November 15, 2002, we may on any one or more occasions redeem up to
35% of the aggregate principal amount of the notes at a redemption price of
110.375% of the principal amount thereof with the net cash proceeds of one or
more Public Equity Offerings and/or Strategic Equity Infusions; provided that:

          (1) at least 65% of the aggregate principal amount of notes remains
     outstanding immediately after such redemption (excluding notes held by us
     or our Subsidiaries); and

          (2) the redemption occurs within 60 days of the date of the Public
     Equity Offering or Strategic Equity Investment.

     Except pursuant to the preceding paragraph and the provisions of the
indenture governing the notes described under "-- Optional Redemption -- Change
of Control" below, the notes will not be redeemable at our option prior to
November 15, 2004. After November 15, 2004, we may redeem all or a part of the
notes upon not less than 30 nor more than 60 days' notice, at the redemption
prices (expressed as percentages of principal amount) set forth below plus
accrued interest, if any, on the notes redeemed to the applicable redemption
date (subject to the right of holders of record on the relevant record date to
receive interest due on the relevant interest payment date), if redeemed during
the 12-month period beginning on November 15 of the years indicated below:

</TABLE>

SELECTION AND NOTICE

     If less than all the notes are to be redeemed at any time, the trustee
under the applicable indenture will select notes for redemption as follows:

          (1) if the notes are listed on any national securities exchange, in
     compliance with the requirements of the principal national securities
     exchange, if any, on which the notes are listed; or

          (2) if the notes are not listed on any national securities exchange,
     on a pro rata basis, by lot or by such method as the trustee shall deem
     fair and appropriate.

     No notes of $1,000 principal amount at maturity or less will be redeemed in
part. Notices of redemption will be mailed by first class mail at least 30 but
not more than 60 days before the redemption date to each holder of notes to be
redeemed at its registered address. Notices of redemption may not be
conditional.

     If any note is to be redeemed in part only, the notice of redemption that
relates to such note shall state the portion of the principal amount of that
note to be redeemed. A new note in principal

                                       22
<PAGE>   26

amount equal to the unredeemed portion of the original note presented for
redemption will be issued in the name of the holder of such note upon
cancellation of the original note. Notes called for redemption become due on the
date fixed for redemption. On and after the redemption date, interest ceases to
accrue or accrete on notes or portions of them called for redemption.

MANDATORY REDEMPTION

     We are not required to make mandatory redemption or sinking fund payments
with respect to the notes.

OPTIONAL REDEMPTION -- CHANGE OF CONTROL

     If a Change of Control Triggering Event occurs, we will have the right to
repurchase in whole the notes at a redemption price equal to the greater of:

          (1) 101% of the aggregate principal amount of the notes plus accrued
     and unpaid interest (subject to the right of holders of record on the
     relevant record date to receive interest due on the relevant interest
     payment date), and

          (2) the sum of the present values of the remaining scheduled payments
     of principal and interest thereon (not including the portion of any such
     payments of interest accrued as of the redemption date) discounted to the
     redemption date on a semiannual basis at the Adjusted Treasury Rate, plus
     accrued and unpaid interest.

A "Change of Control Triggering Event" will be deemed to have occurred if a
Change of Control and a Rating Decline occur. A"Rating Decline" will be deemed
to have occurred if at any time within the earlier of (1) 90 days after the date
of public notice of a Change of Control, or of our intention or the intention of
any Person to effect a Change of Control and (2) the occurrence of the Change of
Control (which period shall in either event be extended so long as the rating of
the notes is under publicly announced consideration for possible downgrade by a
Rating Agency), the rating of the notes is decreased by either Rating Agency by
one or more Gradations and the rating by both Rating Agencies on the notes
following such downgrade is below Investment Grade.

     Within 30 days following any Change of Control Triggering Event, we will
mail a notice to each holder and each holder of our senior Indebtedness
containing similar provisions to those set forth in the indentures describing
the transaction or transactions that constitute the Change of Control Triggering
Event and indicating our intention to repurchase the notes and such other senior
Indebtedness (in which case the provisions of the indentures described under
"-- Repurchase at the Option of Holders -- Change of Control" will not be
applicable) on the Change of Control Payment Date specified in the notice. The
Change of Control Payment Date will be no earlier than 30 days and no later than
60 days from the date the notice is mailed, pursuant to the procedures required
by the indentures and described in such notice.

REPURCHASE AT THE OPTION OF HOLDERS

CHANGE OF CONTROL

     If a Change of Control Triggering Event occurs, each holder of notes will
have the right to require us to repurchase all or any part (equal to $1,000 or
an integral multiple of $1,000) of such holder's notes. The offer price will be
payable in cash and will be 101% of the aggregate principal amount of the notes
plus accrued and unpaid interest on the notes (subject to the right of holders
of record on the relevant record date to receive interest due on the relevant
interest payment date), to the date of purchase. Within 30 days following any
Change of Control Triggering Event, we will mail

                                       23
<PAGE>   27

a notice to each holder, and each holder of our senior indebtedness containing
provisions similar to those set forth in the indenture, describing the
transaction or transactions that constitute the Change of Control Triggering
Event and offering to repurchase notes and such other senior Indebtedness on the
Change of Control Payment Date specified in the notice. The Change of Control
Payment Date will be no earlier than 30 days and no later than 60 days from the
date the notice is mailed, pursuant to the procedures required by the indenture
and described in such notice.

     On the Change of Control Payment Date, we will, to the extent lawful:

          (1) accept for payment all notes or portions of notes properly
     tendered;

          (2) deposit with the paying agent an amount equal to the Change of
     Control Payment in respect of all notes or portions of notes properly
     tendered; and

          (3) deliver or cause to be delivered to the trustee the notes so
     accepted together with an Officers' Certificate stating the aggregate
     principal amount of notes or portions of the notes being purchased by us.

     The paying agent will promptly mail to each holder of notes properly
tendered the Change of Control Payment for such notes, and the trustee will
promptly authenticate and mail (or cause to be transferred by book entry) to
each holder a new note equal in principal amount to unpurchased portion of the
notes surrendered, if any; provided that the new note will be in a principal
amount of $1,000 or an integral multiple of $1,000.

     The Change of Control Triggering Event provisions described above will be
applicable whether or not any other provisions of the indentures are applicable.
We will comply with the requirements of Section 14(e) of the Exchange Act and
any other securities laws or regulations to the extent those laws and
regulations are applicable.

     Subject to the limitations discussed below, we could, in the future, enter
into certain transactions, including acquisitions, refinancings or other
recapitalizations, that would not constitute a Change of Control under the
indenture, but that could increase the amount of Indebtedness outstanding at
such time or otherwise affect our capital structure. The Aerial merger will not
be a Change of Control. Certain restrictions on our ability to incur additional
Indebtedness are contained in the covenants described under
"-- Covenants -- Limitation on Consolidated Indebtedness,"
"-- Covenants -- Limitation on Liens" and "-- Certain Covenants -- Limitation on
Sale and Leaseback Transactions". Such restrictions can only be waived with the
consent of the holders of a majority in principal amount of the notes then
outstanding. Except for the limitations contained in the covenants, however, the
indenture will not contain any covenants or provisions that may afford holders
of the notes protection in the event of certain highly leveraged transactions.

     Our credit facility limits our access to the cash flow of our Subsidiaries
and will, therefore, restrict our ability to purchase any notes. Our Credit
Facility also provides that the occurrence of certain change of control events
constitutes a default under the Credit Facility. In the event that a Change of
Control Triggering Event occurs at a time when our Subsidiaries are prohibited
from making distributions to us to purchase notes, and assuming the Aerial
reorganization is completed, Aerial Subsidiaries will be prohibited from making
distributions to Aerial, thus restricting our ability to purchase notes, we
could cause those Subsidiaries to seek the consent of the lenders under the
credit facility to allow the distributions or could attempt to refinance the
Credit Facility. If we do not obtain a consent or repay such borrowings, we will
remain prohibited from purchasing notes. In that case, our failure to purchase
tendered notes would constitute an Event of Default under the indentures which
would, in turn, constitute a default under the Credit Facility. Future
Indebtedness may also contain prohibitions on the occurrence of certain events
that would constitute a Change of

                                       24
<PAGE>   28

Control or require such future Indebtedness to be repurchased if a Change of
Control occurs. Moreover, the exercise by the holders of their right to require
us to repurchase the notes could cause a default under such Indebtedness, even
if the Change of Control itself does not, due to the financial effect of such
repurchase on us. Finally, our ability to pay cash to the holders of notes
following the occurrence of a Change of Control Triggering Event may be limited
by our then-existing financial resources, including our ability to access the
cash flow of our Subsidiaries, including any Subsidiaries of Aerial that become
Subsidiaries upon completion of the Aerial reorganization. See "Risk
Factors -- The notes are the obligations of a holding company which has no
operations and depends on subsidiaries for cash and its subsidiaries may be
limited in their ability to make funds available". There can be no assurance
that sufficient funds will be available when necessary to make any required
repurchases.

     The provision under the indenture relating to our obligation to make an
offer to repurchase the notes as a result of a Change of Control Triggering
Event may be waived or modified with the written consent of the holders of a
majority in principal amount of our senior notes.

     The definition of Change of Control includes a phrase relating to the sale,
transfer or other conveyance of "all or substantially all" of our assets on a
consolidated basis. Although there is a developing body of case law interpreting
the phrase "substantially all," there is no precise established definition of
the phrase under applicable law. Accordingly, the ability of a holder of notes
to require us to repurchase the notes as a result of a sale, transfer or other
conveyance of less than all of our assets to another Person or group may be
uncertain.

ASSET DISPOSITION

     We and our respective Restricted Subsidiaries will not consummate an Asset
Disposition unless:

          (1) we (or the Restricted Subsidiary, as the case may be) receive
     consideration at the time of such Asset Disposition at least equal to the
     Fair Market Value of the assets issued or sold or otherwise disposed of;
     and

          (2) at least 75% of the consideration received in such Asset
     Disposition by us or such Restricted Subsidiary is in the form of cash or
     readily marketable cash equivalents, the assumption of Indebtedness of ours
     or any Restricted Subsidiary or assets of a Telecommunications Business.

     Within the applicable time period specified below, we or the Restricted
Subsidiary may apply Net Available Proceeds from an Asset Disposition to:

          (1) invest in assets of a Telecommunications Business or in a Person
     engaged in a Telecommunications Business; or

          (2) permanently repay any of our Indebtedness or any Indebtedness of a
     Restricted Subsidiary.

     Any Net Available Proceeds from Asset Dispositions that are not applied or
invested in accordance with the preceding paragraph within 365 days from the
date of such Asset Disposition, or within 18 months of such Asset Disposition if
we or a Restricted Subsidiary has entered into a binding agreement to invest in
such assets or Person, will be deemed to constitute Excess Proceeds. When the
aggregate amount of Excess Proceeds exceeds $10 million (taking into account
income earned on such Excess Proceeds), we will be required to make an Offer to
Purchase to all holders of notes and all holders of our other senior
Indebtedness containing provisions similar to those set forth in the indenture,
on a pro rata basis according to principal amount, to purchase the maximum

                                       25
<PAGE>   29

principal amount (or accreted value, as applicable) of notes and our other
senior Indebtedness that may be purchased out of the Excess Proceeds. The offer
price in any Offer to Purchase will be payable in cash and will be 100% of the
principal amount of the notes, plus accrued and unpaid interest to the date of
purchase. In the case of any other senior Indebtedness, the offer price will be
100% of the principal amount (or accreted value, as applicable) of the
Indebtedness plus accrued and unpaid interest thereon, if any, to the date of
purchase. If the aggregate principal amount of notes and our other senior
Indebtedness surrendered for purchase by holders exceeds the amount of Excess
Proceeds, then the notes and our other senior Indebtedness will be purchased pro
rata according to the outstanding principal amount of such notes and our other
senior Indebtedness with such adjustments as may be deemed appropriate by us so
that only notes in denominations of $1,000 or integral multiples thereof shall
be purchased. To the extent that any portion of the amount of Net Available
Proceeds remains after compliance with the preceding sentence and provided that
all holders of notes and other senior Indebtedness have been given the
opportunity to tender their notes or other senior Indebtedness for purchase
pursuant to the Offer to Purchase, we or the Restricted Subsidiary may use the
remaining amount at their own discretion.

COVENANTS

LIMITATION ON CONSOLIDATED INDEBTEDNESS

     We and our respective Restricted Subsidiaries will not, incur any
Indebtedness unless our Indebtedness to EBITDA Ratio, after giving pro forma
effect thereto, is less than

</TABLE>

     Furthermore, the first paragraph of this covenant will not prohibit the
incurrence of any of the following items of Indebtedness:

          (1) Indebtedness of ours or any of our Restricted Subsidiaries, as the
     case may be, that is outstanding or committed at the time of the issuance
     of the notes;

          (2) Indebtedness of ours or any of our Restricted Subsidiaries, as the
     case may be, that is incurred under our Credit Facility;

          (3) Telecommunications Indebtedness;

          (4) the incurrence by us or any of our Restricted Subsidiaries of
     Acquired Indebtedness in connection with the acquisition of assets or a new
     Subsidiary and the incurrence by our Restricted Subsidiaries of
     Indebtedness as a result of the designation of an Unrestricted Subsidiary
     as a Restricted Subsidiary; provided that, in the case of any such
     incurrence of Acquired Indebtedness, such Acquired Indebtedness was
     incurred by the prior owner of such assets or such Restricted Subsidiary
     prior to such acquisition by us or one of our Restricted Subsidiaries and
     was not incurred in connection with, or in contemplation of, the
     acquisition by us or one of our Restricted Subsidiaries; and provided
     further that, in the case of any incurrence pursuant to this clause (4), as
     a result of such acquisition by us or one of our Restricted Subsidiaries,
     we and our respective Restricted Subsidiaries would be permitted to incur
     an additional $1.00 of Indebtedness pursuant to the first paragraph of this
     covenant, as applicable;

          (5) the incurrence by us or any of our Restricted Subsidiaries of
     Indebtedness represented by Capital Lease Obligations, mortgage financings
     or purchase money obligations, in each case incurred for the purpose of
     financing all or any part of the purchase price or cost of construction or
     improvement of property, plant or equipment used in our business or the
     business of such

     Restricted Subsidiary, in an aggregate principal amount, including all
     Indebtedness incurred to refund, refinance or replace any other
     Indebtedness incurred pursuant to this clause (5), not to exceed $25
     million at any one time outstanding;

          (6) Indebtedness of ours or any of our Restricted Subsidiaries owing
     to us or any of our Restricted Subsidiaries;

          (7) Indebtedness of ours or any of our Restricted Subsidiaries to
     renew, extend, refinance or refund any Indebtedness of ours or any of our
     Restricted Subsidiaries outstanding or committed on the date of renewal,
     extension, refinancing or refunding other than Indebtedness incurred
     pursuant to clause (2) or (6); provided, however, that such Indebtedness
     does not exceed the principal amount of outstanding or committed
     Indebtedness so renewed, extended, refinanced or refunded plus financing
     fees and other expenses (including make-whole or other repurchase payments
     or premiums) associated therewith; provided, further, that

             (a) such renewing, extending, refinancing or refunding Indebtedness
        has a final maturity date the same as or later than the final maturity
        date of the Indebtedness being renewed, extended, refinanced or
        refunded;

             (b) in the case of any refinancing or refunding of Indebtedness
        pari passu to the notes, the refinancing or refunding Indebtedness is
        made pari passu or subordinated to the notes and, in the case of any
        refinancing or refunding of Indebtedness subordinated to the notes, the
        refinancing or refunding Indebtedness is made subordinate to the notes
        to substantially the same extent as the Indebtedness refinanced or
        refunded; and

             (c) such renewing, extending, refinancing or refunding Indebtedness
        shall have an average life equal to or longer than the life of the
        Indebtedness being renewed, extended, refinanced or refunded;

          (8) any Guarantee by any Restricted Subsidiary of any Indebtedness
     incurred under the Credit Facility in compliance with this paragraph;

          (9) Indebtedness of ours or any of our Restricted Subsidiaries under
     (or constituting reimbursement obligations with respect to) letters of
     credit, performance or surety bonds or similar instruments issued in the
     ordinary course of a Telecommunications Business, including letters of
     credit in respect of workers' compensation claims or self-insurance,
     provided, however, that upon the drawing of any such letter of credit or
     other instrument, such obligations are reimbursed within 90 days following
     such drawing;

          (10) Indebtedness arising from agreements providing for
     indemnification, purchase price adjustments or similar obligations, or from
     guarantees of letters of credit, surety bonds or performance bonds securing
     any obligation of ours or any of our Restricted Subsidiaries pursuant to
     such agreements, in any case incurred in connection with the disposition of
     any business, assets or Restricted Subsidiary of ours (other than
     guarantees of Indebtedness incurred by any Person acquiring all or any
     portion of such business, assets or Restricted Subsidiary of ours for the
     purpose of financing such acquisition), in an amount not to exceed the
     gross proceeds actually received by us or any Restricted Subsidiary in
     connection with such disposition;

     under Interest Rate Agreements or Currency Protection Agreements to hedge
     permitted Indebtedness;

          (14) Indebtedness due and owing to governmental entities in connection

     committed.

     Notwithstanding the foregoing, the maximum amount of Indebtedness that we
or any of our Restricted Subsidiaries may incur shall not be deemed to be
exceeded due solely to the result of fluctuations in the exchange rates of
currencies.

     For purposes of determining any particular amount of Indebtedness under the
foregoing clauses, (1) Guarantees, Liens or obligations with respect to letters
of credit supporting Indebtedness otherwise included in the determination of
such particular amount shall not be included and (2) any Liens granted pursuant
to the equal and ratable provisions described below shall not be treated as
Indebtedness. For purposes of determining compliance with the Indebtedness
incurrence restriction, in the event that an item of Indebtedness meets the
criteria of more than one of the types of Indebtedness described in the above
clauses, we may be, in its respective sole discretion shall classify such item
of Indebtedness and only be required to include the amount and type of such
Indebtedness in one of such clauses.

LIMITATION ON RESTRICTED PAYMENTS

          (1) no Event of Default or event which with notice or lapse of time or
     both would become an Event of Default has occurred or is continuing;

          (2) we would be permitted to incur an additional $1.00 of Indebtedness
     pursuant to the first paragraph of the covenant described under
     "-- Limitation on Consolidated Indebtedness"; and

          (3) the total of all Restricted Payments made on or after the date of

        Interests or of our debt securities that have been converted into such
        Capital Stock (other than to a Restricted Subsidiary);

             (c) an amount equal to the net reduction in Investments made by us
        or our Restricted Subsidiary subsequent to the date of the indenture in
        any Person resulting from:

           or advances, or other transfers or distributions of property, in each

           disposition, if any); and

                (C) the redesignation of any Unrestricted Subsidiary as a
           Restricted Subsidiary, in which case such aggregate amount of the net
           reduction in Investments will not exceed the amount of such
           Investments previously made by us and our respective Restricted
           Subsidiaries in such Person or Unrestricted Subsidiary, as the case
           may be, which were treated as Restricted Payments; and

or both would become an Event of Default has occurred and is continuing (other
than in the case of clause (2) below), the preceding provisions will not
prohibit:

     for all such repurchased, redeemed or otherwise acquired Equity Interests
     shall not exceed $2.0 million in any fiscal year;

          (5) the repurchase, redemption or other acquisition or retirement for
     value of our Equity Interests to the extent necessary in the good faith
     judgment of the Board of Directors evidenced by a Board Resolution

     reinstatement of any material license or franchise held by us or any
     Restricted Subsidiary from any government agency;

          (6) the repurchase of Indebtedness subordinated to the notes at a
     purchase price not greater than 101% of the principal amount thereof (plus
     accrued and unpaid interest) pursuant to a mandatory offer to repurchase

LIMITATIONS CONCERNING DISTRIBUTIONS AND TRANSFERS BY RESTRICTED SUBSIDIARIES

     We and our Restricted Subsidiaries will not create or otherwise cause or
suffer to exist or become effective any consensual restriction or prohibition on
the ability of any Restricted Subsidiary to:

          (1) pay dividends on, or make other distributions in respect of, its
     Capital Stock, or any other ownership interest or participation in, or

restrictions existing under or by reason of:

          (1) any agreement in effect on the date of the indentures;

          (2) an agreement relating to any Indebtedness of such Restricted
     Subsidiary which was outstanding or committed prior to the date on which
     such Restricted Subsidiary was acquired by us other than in anticipation of
     becoming a Restricted Subsidiary;

          (3) an agreement described in (1), (2) or (4) of this paragraph
     effecting a renewal, extension, refinancing or refunding of any existing
     agreement, provided, however, that the provisions contained in such
     renewal, extension, refinancing or refunding agreement relating to such
     encumbrance or restriction are no more restrictive in any material respect
     than the provisions contained in the agreement the subject thereof;

          (4) an agreement entered into after the date of the indenture relating
     to any Indebtedness the incurrence of which is permitted under the
     indenture, provided, however, that the provisions contained in such
     agreement relating to such encumbrance or restriction are either no more
     restrictive in any material respect than those contained in the indenture
     or no more restrictive in any material respect than those contained in the
     credit facility;

          (5) an agreement by which we or any of our Restricted Subsidiaries
     obtain financing, provided that (A) such restriction is not materially more
     restrictive than customary provisions in comparable financing agreements
     and (B) our management determines that at the time such agreement is
     entered into such restriction will not materially impair our ability to
     make payments on the notes, such determination to be confirmed by an
     Officers' Certificate delivered to the trustee;

          (9) restrictions of the type referred to in clause (3) of the
     preceding paragraph contained in security agreements securing Indebtedness
     of ours or a Restricted Subsidiary of ours to the extent that such Liens
     were otherwise incurred in accordance with the covenant described under

                                       30
<PAGE>   34

     "-- Limitation on Liens" and restrict the transfer of the collateral
     subject to such agreements without restricting the transfer of other
     property; or

          (10) an agreement that has been entered into for the sale or
     disposition of all or substantially all of the Capital Stock of, or
     property and assets of, a Restricted Subsidiary of ours.

     Nothing contained in the foregoing clauses shall prevent us or any of our
Restricted Subsidiaries from (1) creating, incurring, assuming or suffering to
exist any Liens otherwise permitted under the indenture or (2) restricting the
sale or other disposition of property or assets of ours or any of our Restricted
Subsidiaries that secure Indebtedness of ours or any of our Restricted
Subsidiaries.

LIMITATION ON ISSUANCES AND SALES OF CAPITAL STOCK OF RESTRICTED SUBSIDIARIES

     We and our Restricted Subsidiaries will not, transfer, convey, sell, lease
or otherwise dispose of any Capital Stock of such Restricted Subsidiary or any
other Restricted Subsidiary to any Person other than us or a Restricted
Subsidiary; and will not permit any Restricted Subsidiary to issue shares of its
Capital Stock or securities convertible into, or warrants, rights or options, to
subscribe for or purchase shares of, its Capital Stock to any Person other than
us or a Restricted Subsidiary, unless, in each such case:

          (1) immediately after giving effect to such issuance or sale, such
     Restricted Subsidiary would no longer constitute a Restricted Subsidiary
     and any Investment in such Person remaining after giving effect to such
     issuance or sale would have been permitted to be made under the provision
     of the indenture described under "-- Limitation on Restricted Payments"; or

          (2) if such sale or disposition is effected in accordance with the
     terms of the provision of the indenture described under "-- Repurchase at
     the Option of Holders -- Asset Dispositions".

     The foregoing shall not prohibit the issuance of Capital Stock of our
Restricted Subsidiary pursuant to an employee stock option plan approved by the
Boards of Directors of the Restricted Subsidiary and us.

LIMITATIONS ON TRANSACTIONS WITH AFFILIATES AND RELATED PERSONS

     We and our respective Restricted Subsidiaries will not enter into any
transaction involving aggregate consideration in excess of $5 million,
including, without limitation, any purchase, sale, lease or exchange of property
or the rendering of any service, with or to any Affiliate or Related Person
(other than a Restricted Subsidiary) (each of the foregoing, an "Affiliate
Transaction"), unless our management determines (which determination will be
evidenced by an Officers' Certificate) that:

          (1) such transaction is in the best interests of ours or such
     Restricted Subsidiary; and

          (2) such transaction is on terms that are no less favorable to ours or
     a Restricted Subsidiary than those which might be obtained in arm's length
     transactions with a third party at the time.

     In the event that any transaction contemplated by the preceding paragraph
involves aggregate consideration in excess of $10 million, a determination by a
majority of the disinterested members of our Board of Directors (which
determination shall be evidenced by a Board Resolution) will be required with
respect to clause (1) and (2) above.

                                       31
<PAGE>   35

     Notwithstanding the foregoing, the following items will not be deemed to be
Affiliate Transactions:

          (1) transactions between or among us and/or our Restricted
     Subsidiaries (other than a Restricted Subsidiary in which an Affiliate or

     Capital Stock);

          (2) customary payment of compensation to employees, officers or

     to the rules and regulations of the Commission), or any agreement in effect
     at the time that an entity becomes a Restricted Subsidiary or is merged
     into us (and was not entered into in anticipation of such acquisition), or
     any amendment thereto or replacement of such agreement so long as any such
     amendment or replacement is not disadvantageous to the holders in any
     material respect; and

          (5) loans or advances to officers or employees of ours or our
     Restricted Subsidiary to pay business related travel expenses or reasonable
     relocation costs of such officers or employees in connection with their
     employment by us or any of our Restricted Subsidiaries.

LIMITATION ON LIENS

     We and our Restricted Subsidiaries will not incur or suffer to exist any
Lien on or with respect to any property or assets now owned or hereafter
acquired to secure any Indebtedness without making, or causing such Restricted
Subsidiary to make, effective provision for securing the notes:

          (1) equally and ratably with such Indebtedness as to such property for
     so long as such Indebtedness will be so secured; or

          (2) in the event such Indebtedness is Indebtedness of over which is
     subordinate in right of payment to the notes, prior to such Indebtedness as
     to such property for so long as such Indebtedness will be so secured.

     The foregoing restrictions will not apply to the following Permitted Liens:

     date of the indentures or is outstanding or permitted under our Credit

             (a) the principal amount of any Indebtedness secured by such a Lien
        does not exceed 100% of such purchase price or cost;

             (b) such Lien does not extend to or cover any other property other
        than such item of property or any improvements on such item; and

        the indenture;

     acquisition thereof (and not incurred in anticipation of the financing of
     such acquisition);

     (or successive extensions, renewals, refinancings or refundings), in whole
     or in part, Indebtedness secured by any Lien referred to in the foregoing
     clauses (1), (3) and (4) so long as such Lien does not extend to any other
     property and the principal amount of Indebtedness so secured is not
     increased except as otherwise permitted under the provision of the
     indentures described under clause (2) or (7) of "-- Limitation on
     Consolidated Indebtedness";

          (9) Liens for taxes, assessments or governmental charges or claims
     that are not yet delinquent or that are being contested in good faith by

     have been made therefor;

          (10) Carriers', warehousemen's, mechanics', landlords', materialmen's,
     repairmen's or other like Liens arising in the ordinary course of business
     in respect of obligations that are not yet due, are bonded or are being
     contested in good faith by appropriate proceedings if adequate reserves

     accounting principles; and

          (11) Liens securing Interest Rate Agreements entered into in the
     ordinary course of business on any property also securing the permitted
     Indebtedness to which such Interest Rate Agreements relate.

LIMITATION ON SALE AND LEASEBACK TRANSACTIONS

Leaseback Transaction with respect to any property of ours or any of our
Restricted Subsidiaries (other than a Sale and Leaseback Transaction between us
or a Restricted Subsidiary or any of them).

                                       33
<PAGE>   37

     The preceding covenant will not prohibit us or any of our Restricted
Subsidiaries from entering into a Sale and Leaseback Transaction if:

     equally and ratably securing the notes; and

          (2) the Sale and Leaseback Transaction is treated as an Asset
     Disposition and the provision in the indenture described under
     "-- Repurchase at the Option of Holders -- Asset Disposition" is satisfied
     with respect to such Sale and Leaseback Transaction.

PROVISION OF FINANCIAL INFORMATION

     Whether or not required by the SEC, so long as any notes are outstanding,
we will file with the Commission the annual reports, quarterly reports and other
documents which we would have been required to file with the Commission pursuant
to such Section 13(a) or 15(d) or any successor provision thereto if we were so
required, such documents to be filed with the Commission on or prior to the
respective dates (the "Required Filing Dates") by which we would have been
required so to file such documents if we were so required.

     In addition, whether or not required by the SEC, so long as any notes are
outstanding, we will furnish to the holders of notes and the trustee within 15
days of each Required Filing Date copies of the annual reports, quarterly
reports and other documents which we file with the Commission pursuant to such
Section 13(a) or 15(d) or any successor provision thereto or would have been
required to file with the Commission pursuant to such Section 13(a) or 15(d) or
any successor provisions thereto if we were required to be subject to such
Sections. If filing such documents by us, with the Commission is not permitted
under the Securities Exchange Act of 1934, we will promptly upon written request
supply copies of such documents to any prospective holder.

CONSOLIDATION, MERGER, CONVEYANCE, TRANSFER OR LEASE

     We will not consolidate with or merge into any Person or permit any other
Person to consolidate with or merge into us, or transfer, sell, convey or lease
or otherwise dispose of all or substantially all of our assets to, any Person
unless:

          (1) (a) we are the surviving entity or (b) if such we are not the
     surviving entity then the successor or transferee is a corporation
     organized under the laws of the United States, any state thereof or the
     District of Columbia and assumes all our obligations under the notes and
     the indentures,

          (2) after giving effect to such transaction, no Event of Default or
     event which with notice or lapse of time would become an Event of Default
     has occurred,

          (3) (a) immediately after giving effect to such transaction, we would
     be permitted to incur at least $1.00 of additional Indebtedness pursuant to
     the provision of the indenture described in the first paragraph under
     "-- Limitation on Consolidated Indebtedness" or (b) after giving effect to
     such transaction the Indebtedness to EBITDA Ratio is not higher than the
     Indebtedness to EBITDA Ratio prior to giving effect to such transaction;

                                       34
<PAGE>   38

EVENTS OF DEFAULT AND REMEDIES

     Each of the following constitutes an Event of Default under the indentures:

          (1) failure to pay the principal of the notes when due and payable;

          (2) failure for 30 days to pay the interest, if any, on the notes when
     due and payable;

          (3) failure to perform or comply with the provisions of the indenture
     described under "-- Consolidation, Merger, Conveyance, Transfer or Lease";

          (4) failure to perform any other covenant or agreement of ours under
     the indenture continued for 30 days after written notice to us by the
     trustee or holders of at least 25% in aggregate principal amount of
     outstanding notes;

          (5) default by us or any of our respective Restricted Subsidiaries
     under the terms of any instrument evidencing or securing Indebtedness
     having an outstanding principal amount in excess of $25 million in the
     aggregate, which default results in the acceleration of the payment of such
     Indebtedness or constitutes the failure to pay the principal of such
     Indebtedness at maturity;

          (6) the rendering of a final judgment or judgments against us or any
     of our Restricted Subsidiaries in an amount in excess of $25 million which
     remains undischarged or unstayed for a period of 60 days after the date on
     which the right of appeal has expired; and

          (7) certain events of bankruptcy, insolvency or reorganization
     described in the indentures affecting either us or a Restricted Subsidiary.

     If an Event of Default, other than an event described under (7) above,
occurs and is continuing, either the trustee or the holders of at least 25% in
aggregate principal amount of the notes of either series by notice as provided
in the applicable indenture may declare the principal amount of the notes of
such series to be due and payable immediately; provided, however, that after
such acceleration, but before a judgment or decree based on acceleration, the
holders of a majority in aggregate principal amount of outstanding Notes of such
series may, under certain circumstances, rescind and annul such acceleration if
all Events of Default, other than the nonpayment of accelerated principal of the
Notes, have been cured or waived as provided in the applicable indenture. If an
Event of Default described under (7) above shall occur, the Notes will become
immediately due and payable without any declaration or other act on the part of
the trustee or any holder.

     No holder of any Note will have any right to institute any proceeding with
respect to the applicable indenture or for any remedy thereunder, unless such
holder has previously given to the trustee written notice of an Event of Default
and unless the holders of at least 25% in aggregate principal amount of the
outstanding Notes of the applicable series have made written request to the
trustee and the trustee has not received from the holders of a majority in
aggregate principal amount of the outstanding Notes of such series a direction
inconsistent with such request and has failed to institute such proceeding
within 60 days. However, such limitations do not apply to a suit instituted by a
holder of a Note for enforcement of payment of the principal of and premium, if
any, or interest on such Note on or after the respective due dates expressed in
such note. The holders of a majority in aggregate principal amount of the notes
of the applicable series outstanding may waive any existing Default except a
Default in the payment of interest or principal (including premium) on the
notes.

FORM, DENOMINATION, TRANSFER, EXCHANGE AND BOOK-ENTRY PROCEDURES

     The notes will be issued in fully registered form, without interest

     Person is merged with or into or became a Subsidiary of such specified
     Person, including, without limitation, Indebtedness incurred in connection
     with, or in contemplation of, such other Person merging with or into or
     becoming a Subsidiary of such specified Person; and

          (2) Indebtedness secured by a Lien encumbering any asset acquired by
     such specified Person.

     "Adjusted Treasury Rate" will be determined on the third business day
preceding any applicable redemption date and is the sum of:

     date of determination under the caption "Treasury Constant Maturities" for
     the maturity (rounded to the nearest month) corresponding to the remaining
     life to maturity, as of the redemption date, of the principal being
     redeemed; and

in each of the relevant periods to the nearest month.

securities, by contract or otherwise; and the terms "controlling" and
"controlled" have meanings correlative to the foregoing.

     "Asset Disposition" by any Person means any transfer, conveyance, sale,
lease or other disposition by such Person or any of its Restricted Subsidiaries
(including a consolidation or merger or other sale of any such Restricted

disposition by a Subsidiary of such Person to such Person or a Wholly Owned
Restricted Subsidiary of such Person or by such Person to a Wholly Owned

obligations in respect of the outstanding notes or (2) if applicable, we may
omit to comply with certain restrictive covenants, and that such omission will
not be deemed to be an Event of Default under the indentures and the notes. In
order to exercise either option, we must first irrevocably deposit with the
trustee, in trust, money and/or U.S. government obligations which will provide
money in an amount sufficient in the opinion of a nationally recognized firm of
independent certified public accountants to pay the principal and premium, if
any, and each installment of interest, if any, on the outstanding notes on

                                       49

and effect.

          (1) (a) in the event of a discharge under (1) of the immediately
     preceding paragraph, we have received from, or there has been published by,
     the Internal Revenue Service a ruling or there has been a change in law
     after the Issue Date, which in the Opinion of Counsel provides that holders
     of the notes will not recognize gain or loss for Federal income tax
     purposes as a result of such deposit, defeasance and discharge has not
     occurred; or (b) in the event of a discharge under (2) of the immediately
     preceding paragraph, we have delivered to the trustee an Opinion of Counsel
     to the effect that the holders of the notes will not recognize gain or loss
     for Federal income tax purposes as a result of such deposit and defeasance
     and will be subject to Federal income tax on the same amounts, in the same
     manner and at the same times as would have been the case if such deposit
     and defeasance had not occurred;

          (2) no Default or Event of Default has occurred or is continuing;

          (3) we have delivered to the trustee an Opinion of Counsel to the
     effect that such deposit shall not cause the trustee or the trust so
     created to be subject to the Investment Company Act of 1940, as amended;
     and

          (4) certain other customary conditions precedent are satisfied.

NOTICES

     Notices to holders of notes will be given by mail to the addresses of such
holders as they may appear in the Security Register.

TITLE

     We, the trustee and any agent of the trustee may treat the Person in whose
name a note is registered as the absolute owner thereof (whether or not such
note may be overdue) for the purpose of making payment and for all other
purposes.

GOVERNING LAW

     The indenture and the notes will be governed by and construed in accordance
with the laws of the State of New York.

THE TRUSTEE

     The indenture provides that, subject to the duty of the trustee during an
Event of Default to act with the required standard of care, the trustee will be
under no obligation to exercise any of its rights or powers under the indenture
at the request or direction of any of the note holders, unless such holders
shall have offered to the trustee reasonable security or indemnity. Subject to
certain provisions, including those requiring security or indemnification of the
trustee, the holders of a majority in principal amount of the notes will have
the right to direct the time, method and place of conducting any proceeding for
any remedy available to the trustee, or exercising any trust or power conferred
on the trustee, in each case with respect to such series.

                                       50
<PAGE>   54

     We will be required to furnish to the trustee annually a statement as to
the performance by us of our obligations under the indenture and as to any
default in such performance.

                         BOOK-ENTRY; DELIVERY AND FORM

     Our new notes will be represented by one or more permanent global notes in
definitive, fully registered form without interest coupons (each a "Global
Note") and will be deposited with the Trustee as custodian for, and registered
in the name of a nominee of, DTC. Ownership of beneficial interests in a Global
Exchange Note will be limited to participants that have accounts with DTC or
persons who hold interests through participants. Ownership of beneficial
interests in a Global Note will be shown on, and the transfer of that ownership
will be effected only through, records maintained by DTC or its nominee (with
respect to interests of participants) and the records of participants (with
respect to interests of persons other than participants). Beneficial owners may
hold their interests in a Restricted Global Note directly through DTC if they
are participants in such system, or indirectly through organization which are
participants in such system.

     So long as DTC, or its nominee, is the registered owner or holder of a
Global Note, DTC or such nominee, as the case may be, will be considered the
sole owner or holder of our new notes represented by such Global Note for all
purposes under our new notes and the Indenture related thereto. No beneficial
owner of an interest in a Global Note will be able to transfer that interest
except in accordance with DTC's applicable procedures, in addition to those
provided for under the indenture.

     Payments of the principal of, and interest on, a Global Note will be made
to DTC or its nominee, as the case may be, as the registered owner thereof.
Neither we, the trustee nor any paying agent will have any responsibility or
liability for any aspect of the records relating to or payments made on account
of beneficial ownership interests in a Global Note or for maintaining,
supervising or reviewing any records relating to such beneficial ownership
interests.

     We expect that DTC or its nominee, upon receipt of any payment of principal
or interest in respect of a Global Note, will credit participant's accounts with
payments in amounts proportionate to their respective beneficial interests in
the principal amount of such Global Note as shown on the records of DTC or its
nominee. We also expect that payments by participants to owners of beneficial
interests in such Global Note held through such participants will be governed by
standing instructions and customary practices, as is now the case with
securities held for the accounts of customers registered in the names of
nominees for such customers. Such payments will be the responsibility of such
participants.

     Transfers between participants in DTC will be effected in the ordinary way
in accordance with DTC rules and will be settled in same-day funds.

     We expect that DTC will take any action permitted to be taken by a holder
of our notes (including the presentation of notes for exchange as described
below) only at the direction of one or more participants to whose account the
DTC interests in a Global Note is credited and only in respect of such portion
of the aggregate principal amount of notes as to which such participant or
participant's has or have given such direction. However, if there is an Event of
Default under the notes, DTC will exchange the applicable Global Note for
Certificated Notes, which it will distribute to its participants.

     We understand that: DTC is a limited purpose trust company organized under
the laws of the State of New York, a "banking organization" within the meaning
of New York Banking Law, a member of the Federal Reserve System, a "clearing
corporation" within the meaning of the Uniform

                                       51
<PAGE>   55

Commercial Code and a "Clearing Agency" registered pursuant to the provisions of
Section 17A of the Exchange Act. DTC was created to hold securities for its
participants and facilitate the clearance and settlement of securities
transactions between participants through electronic book-entry changes in
accounts of its participants, thereby eliminating the need for physical movement
of certificates and certain other organizations. Indirect access to the DTC
system is available to others such as banks, brokers, dealers and trust
companies that clear through or maintain a custodial relationship with a
participant, either directly or indirectly ("indirect participants").

     Although DTC is expected to follow the foregoing procedures in order to
facilitate transfers of interests in a Global Note among participants of DTC, it
is under no obligation to perform or continue to perform such procedures, and
such procedures may be discontinued at any time. Neither the Company nor the
Trustee will have any responsibility for the performance by DTC or its
respective participants or indirect participants of its obligations under the
rules and procedures governing its operations.

     If DTC at any time unwilling or unable to continue as a depositary for the
Global Notes and successor depositary is not appointed by the Company within 90
days, the Company will issue Certificated Notes.

            CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS


     The following discussion summarizes certain United States federal income
tax consequences resulting from the exchange of our notes for Omnipoint's
outstanding notes. It is provided for general informational purposes only. It is
based on the Internal Revenue Code of 1986 (the "Code"), as amended, Treasury
Regulations promulgated thereunder, Internal Revenue Service rulings, and
judicial decisions, all as in effect on the date hereof, and all of which are
subject to change, possibly with retroactive effect. The discussion does not
address all of the U.S. federal income tax consequences that may be relevant to
an Omnipoint noteholder in light of the holder's particular tax situation, nor
does it address any aspect of state, local or foreign taxation. The tax
treatment of a holder may vary depending upon its particular circumstances, and
the discussion does not apply to certain holders (including insurance companies,
tax-exempt organizations, financial institutions, and broker-dealers) that are
members of a class of holders subject to special rules under the Code. The
discussion assumes that the outstanding Omnipoint notes are held as "capital
assets" within the meaning of section 1221 of the Code.


     EACH HOLDER IS URGED TO CONSULT ITS OWN TAX ADVISOR REGARDING THE TAX
CONSEQUENCES TO IT OF TENDERING OR FAILING TO TENDER OMNIPOINT'S NOTES,
INCLUDING THE APPLICATION AND EFFECT OF ANY STATE, LOCAL, FOREIGN OR OTHER TAX
LAW.

U.S. FEDERAL INCOME TAXATION OF U.S. HOLDERS

     The discussion under this heading, "U.S. Federal Income Taxation of U.S.
Holders," assumes that each holder of Omnipoint notes is a U.S. holder, meaning
a holder of notes that is, for U.S. federal income tax purposes, (i) a citizen
or resident of the United States, (ii) a corporation created or organized in or
under the laws of the United States or any political subdivision thereof, (iii)
an estate the income of which is subject to U.S. federal income taxation
regardless of its source, or (iv) a trust if a court within the United States is
able to exercise primary supervision over the administration of the trust and
one or more U.S. persons have the authority to control all substantial decisions
of the trust.

     TAX CONSEQUENCES OF THE OFFER TO U.S. HOLDERS


     Exchange of Outstanding Omnipoint Notes for our Notes. The exchange of an
outstanding Omnipoint note for our new note plus cash equal to the accrued and
unpaid interest on the Omnipoint note will constitute a taxable exchange. As a
result, the U.S. holder will recognize ordinary interest income in an amount
equal to the accrued but unpaid interest on the holder's outstanding Omnipoint
note that has not previously been recognized. In addition, the U.S. holder will
recognize gain or loss equal to the difference between (i) its tax basis in its
outstanding Omnipoint note (less any basis attributable to accrued but unpaid
interest), and (ii) the issue price of our note. The issue price of our notes
should equal their fair market value on the date of the exchange (assuming that
they are "publicly traded" as defined in the applicable Treasury Regulations).
Any gain or loss recognized generally would be capital gain or loss, and would
be long-term if the U.S. holder has held the outstanding Omnipoint note for more
than one year at the time of the exchange. However, a U.S. holder who purchased
its outstanding Omnipoint note for less than its principal amount may recognize
ordinary income rather than capital gain under the "market discount" rules
discussed under the heading "Market Discount" below.



     The U.S. holder's tax basis in our note should equal the issue price of the
note, as set forth in the preceding paragraph, and the U.S. holder will have a
new holding period for such note beginning on the day after the exchange.



     Market Discount. An Omnipoint noteholder that is subject to gain
recognition under any of the rules discussed above and that purchased the
Omnipoint notes for less than their principal amount may recognize ordinary
income rather than capital gain under the market discount rules. Under these
rules, unless the U.S. holder has made an election to include market discount in
income as it accrues, any gain recognized by the U.S. holder will be treated as
ordinary income to the extent of any market discount that has accrued for the
period the Omnipoint notes have been owned. Market discount generally equals the
excess, if any, of (i) the unpaid principal balance of the note at the time it
is acquired by the U.S. holder, over (ii) the U.S. holder's tax basis in the
note immediately after its acquisition (subject to a de minimis exception
pursuant to which market discount is considered to be zero if it is less than
0.25 percent of the unpaid principal balance of the note multiplied by the
number of complete years to maturity from the date of acquisition). In general,
market discount is treated as accruing over the term of the note on a
straight-line basis unless the U.S. holder elects to accrue on a constant-yield
basis. If the gain recognized by a U.S. holder is in excess of the accrued
market discount, such excess will generally be treated as capital gain.


     TAX CONSEQUENCES FOR A U.S. HOLDER OF HOLDING OUR NOTES


     Payment of Interest on Our Notes. Interest paid or payable on our notes
generally will be taxable to a U.S. holder as ordinary interest income, at the
time it is received or accrued, in accordance with the holder's regular method
of accounting for U.S. federal income tax purposes. A portion of the first
interest payment on the notes equal to the amount that the Omnipoint noteholder
pays us in respect of accrued but unpaid interest on our notes at the time of
their issuance should be excludable from the U.S. holder's income.


     Possible Original Issue Discount on Our Notes. Our notes generally will be
treated as having been issued with original issue discount ("OID") if their
principal amount is greater than their issue price. Under a de minimis rule, if
OID as so calculated is less than .25% of the stated redemption price at
maturity multiplied by the number of complete years to maturity of the note, the
note will not be treated as issued with OID.

                                       53
<PAGE>   57


     We intend to treat our notes issued in exchange for Omnipoint's notes as
part of the same issue as our identical notes that were issued on November 9,
1999 (the "Earlier Notes") if the trading price of the Earlier Notes on the day
of the exchange is equal to or in excess of their principal amount. See
Treatment of Our Notes as Part of the Same Issue with the Earlier Notes, below.
If our notes are treated as part of the same issue with the Earlier Notes, they
should not be treated as issued with OID. If our notes are not part of the same
issue with our Earlier Notes, the issue price of our Notes should be their fair
market value on the date of the exchange (assuming they are "publicly traded" as
defined in the applicable Treasury Regulations) and, as a result they may be
issued with OID. Any amount of OID on the notes must be accrued over the term of
the notes using a constant-yield method. As a result, a U.S. holder may have to
include OID in income before the cash attributable to such income is received.


     Sale, Exchange or Retirement of Our Notes. Upon the sale, exchange,
redemption, retirement at maturity or other disposition of our note, a U.S.
holder generally will recognize taxable gain or loss equal to the difference
between the sum of the cash plus the fair market value of all other property
received (other than any amount that is attributable to accrued but unpaid
interest, which will be treated as ordinary interest income) and the U.S.
holder's tax basis in the note (less any basis attributable to accrued but
unpaid interest). A U.S. holder's tax basis in a note received pursuant for the
offer generally will be as described above, adjusted to include previous
inclusions of OID with respect to the note, if any.


     Gain or loss recognized on the disposition of our new registered note
generally will be capital gain or loss and will be long-term capital gain or
loss if, at the time of such disposition, the U.S. holder has held the note for
more than one year. However, a U.S. holder who purchased our note for less than
its principal amount may recognize ordinary income rather than capital gain
under the "market discount" rules discussed above under the heading "Market
Discount."


     Treatment of Our Notes as Part of the Same Issue with the Earlier
Notes. Our new notes have credit and payment terms that are identical to the
credit and payment terms of the Earlier Notes. As discussed further below, if
the trading price of the Earlier Notes on the day of the exchange is equal to or
in excess of their principal amount, we intend to treat our notes as part of the
same issue with the Earlier Notes.

     Under current Treasury Regulations, two or more debt instruments are part
of the same issue if they have the same credit and payment terms and are sold
reasonably close in time and pursuant to a common plan. At the time the Earlier
Notes were issued, we stated that we intended to offer holders of Omnipoint's
notes the right to exchange their notes for additional Earlier Notes or other
debt securities. Thus, although the issue is not free from doubt, we believe
that our new notes should be viewed as sold pursuant to a common plan with the
Earlier Notes and sold reasonably close in time to the Earlier Notes.


     The Treasury Department has proposed regulations that generally would
require that two or more debt instruments be issued within a 13-day period in
order to be considered part of the same issue. This will not be the case for our
new notes and the Earlier Notes. The proposed regulations are proposed to become
effective prospectively, following their issuance in final form.


     The Treasury Department also has proposed regulations that would allow debt
instruments issued in a "qualified reopening" to be treated as part of the same
issue with earlier-issued debt instruments. Under these proposed regulations, in
order to be part of a qualified reopening, the later-issued debt instruments
must be publicly traded (as defined in relevant Treasury Regulations) and must
(1) have terms that are identical to the earlier-issued debt instruments, (2) be
issued not more than six months after the issue date of the earlier-issued debt
instruments, and (3) not be issued with more

                                       54
<PAGE>   58

than de minimis OID, or meet certain other yield tests. These proposed
regulations are also proposed to become effective prospectively, following their
issuance in final form.


     Although the issue is not free from doubt, we intend to take the position
that our notes and the Earlier Notes are part of the same issue for federal
income tax purposes if the trading price of the Earlier Notes on the day of the
exchange is equal to or in excess of their principal amount. If the trading
price of the Earlier Notes on the day of the exchange is less than their
principal amount, our new notes may be treated as issued with OID, and we will
not treat our new notes as part of the same issue with the Earlier Notes. See
Possible Original Issue Discount on Our Notes, above. EACH HOLDER IS URGED TO
CONSULT ITS OWN TAX ADVISOR REGARDING WHETHER OUR NOTES AND THE EARLIER NOTES
WILL BE PART OF THE SAME ISSUE FOR FEDERAL INCOME TAX PURPOSES IN THE
CIRCUMSTANCES DESCRIBED ABOVE AND THE CONSEQUENCES OF THIS TREATMENT FOR OID AND
OTHER TAX PURPOSES.


U.S. FEDERAL INCOME TAXATION OF FOREIGN HOLDERS

     The discussion under this heading, "U.S. Federal Income Taxation of Foreign
Holders," assumes that a holder of Omnipoint notes is a foreign holder, meaning
a holder of a note that is, for U.S. federal income tax purposes, (a) a
nonresident alien individual, (b) a corporation organized or created under
non-U.S. law, (c) an estate that is not taxable in the United States on its
worldwide income, or (d) a trust that either is not subject to primary
supervision over its administration by a U.S. court or not subject to the
control of a U.S. person with respect to all substantial decisions of the trust.

     THIS DISCUSSION DOES NOT ADDRESS TAX CONSEQUENCES TO FOREIGN HOLDERS THAT
ARE SUBJECT TO U.S. FEDERAL INCOME TAXATION ON A NET BASIS ON INCOME OR GAIN
REALIZED WITH RESPECT TO A NOTE BECAUSE SUCH INCOME IS EFFECTIVELY CONNECTED
WITH THE CONDUCT OF A U.S. TRADE OR BUSINESS.

     Sale or Exchange of Outstanding Omnipoint Notes Pursuant to the Exchange
Offer and Sale, Exchange or Retirement of our Notes. A foreign holder generally
will not be subject to U.S. federal income tax (and generally no tax will be
withheld) with respect to gain realized on the sale or exchange of the
outstanding Omnipoint notes pursuant to the offer, or on the sale, exchange,
redemption, retirement at maturity or other disposition of our note, unless (a)
the foreign holder is an individual who is present in the United States for a
period or periods aggregating 183 or more days in the taxable year of the
disposition and, generally, either has a "tax home" or an "office or other place
of business" in the United States, or (b) the foreign holder is subject to tax
pursuant to the provisions of U.S. federal income tax law applicable to certain
expatriates. In addition, generally no tax will be withheld from any amount
received by a foreign holder pursuant to the exchange offer that is attributable
to accrued but unpaid interest on the holder's outstanding Omnipoint notes if
the holder meets the conditions set forth below under the heading, "Payment of
Interest on Our Notes."


     Payment of Interest on Our Notes. Subject to the discussion of backup
withholding below, if you are a foreign holder of our note, we and our paying
agents will not be required to deduct United States withholding tax from
payments of principal, premium, if any, and interest, including OID, on the
notes to you if, in the case of interest:


     - you do not actually or constructively own 10% or more of the total
       combined voting power of all classes of our stock entitled to vote,

     - you are not a controlled foreign corporation that is related to us
       through stock ownership, and

                                       55
<PAGE>   59

     - you certify to us or a U.S. payor of interest on the notes, under
       penalties of perjury, that you are not a beneficial owner of the notes
       that is a U.S. holder and provide your name and address, or


     - a non-U.S. securities clearing organization, bank or other financial
       institution that holds customers' securities in the ordinary course of
       its trade or business and holds the notes certifies to us or a U.S. payor
       of interest on the notes under penalties of perjury that a similar
       statement has been received from you by it or by a similar financial
       institution between it and you and furnishes the payor with a copy
       thereof.


     Further, a note of ours held by an individual, who at death is not a
citizen or resident of the United States will not be includible in the
individual's gross estate for United States federal estate tax purposes if:

     - the decedent did not actually or constructively own 10% or more of the
       total combined voting power of all classes of our stock entitled to vote
       at the time of death, and

     - the income on the note would not have been effectively connected with a
       United States trade or business of the decedent at the same time.

     If you receive a payment after December 31, 2000, recently finalized
Treasury Regulations will apply. Under these regulations, after December 31,
2000, you may use an alternative method to satisfy the certification requirement
described above. Additionally, if you are a partner in a foreign partnership,
after December 31, 2000, you (in addition to the foreign partnership) must
provide the certification described above. The IRS will apply a look-through
rule in the case of tiered partnerships.

INFORMATION REPORTING AND BACKUP WITHHOLDING

     U.S. HOLDERS


     Information Reporting.  Information statements will be provided to the IRS
and the U.S. holders whose Omnipoint notes are exchanged for our notes,
reporting the payment of the offer consideration (except with respect to holders
that are exempt from the information reporting rules, such as corporations and
tax-exempt organizations).


     Backup Withholding and Substitute Form W-9.  Under U.S. federal income tax
law, a backup withholding tax equal to 31% of the offer consideration will apply
if a U.S. holder who tenders notes is not exempt from backup withholding and (i)
fails to furnish such holder's taxpayer identification number ("TIN") (which,
for an individual, is his or her Social Security Number) to the Exchange Agent
in the manner required, (ii) furnishes an incorrect TIN and the payor is so
notified by the IRS, (iii) is notified by the IRS that such holder has failed to
report repayments of interest and dividends or (iv) in certain circumstances,
fails to certify, under penalties of perjury,that such holder has not been
notified by the IRS that such holder is subject to backup withholding. Backup
withholding is not an additional tax. Rather, any amounts withheld from a
payment to a holder under the backup withholding rules are allowed as a refund
or credit against such holder's U.S. federal income tax liability, provided that
the required information is furnished to the IRS.

     FOREIGN HOLDERS

     You are generally exempt from backup withholding and information reporting
with respect to any payments of principal, premium or interest, made by us and
our payors provided that you provide the certification described under the
heading, "U.S. Federal Income Taxation of Foreign Holders --

                                       56
<PAGE>   60

Payment of Interest on our Notes," and provided further that the payor does not
have actual knowledge that you are a U.S. holder. In this regard, you should
note the discussion above under the same heading with respect to the rules under
the final withholding regulations.


     In general, payment of the proceeds from the sale or taxable exchange of
notes to or through a United States office of a broker is subject to both United
States backup withholding and information reporting, unless you are a foreign
holder and certify as to your non-U.S. status under penalties of perjury or
otherwise establish an exemption. Payments of the proceeds from the sale or
taxable exchange by a foreign holder of a note made to or through a foreign
office of a broker will not be subject to information reporting or backup
withholding. However, information reporting, but not backup withholding, may
apply to a payment made outside the United States of the proceeds of a sale or
taxable exchange of a note through an office outside the United States if the
broker is:


     - a United States person,

     - a controlled foreign corporation for United States tax purposes,

     - a foreign person 50% or more of whose gross income is effectively
       connected with a United States trade or business for a specified
       three-year period, or

     - with respect to payments made after December 31, 2000, a foreign
       partnership, if at any time during its tax year:

      - one or more of its partners are "U.S. persons" (as defined in U.S.
        Treasury regulations) who in the aggregate own more than 50% of the
        income or capital interest in the partnership, or

      - such foreign partnership is engaged in a United States trade or
        business,

unless the broker has documentary evidence in its records that you are a
non-U.S. person and does not have actual knowledge that you are a U.S. person,
or you otherwise establish an exemption.

                              PLAN OF DISTRIBUTION

     Notes received by broker-dealers for their own account pursuant to the
exchange offer may be sold from time to time in one or more transactions in the
over-the-counter market, in negotiated transactions, through the writing of
options on the notes or a combination of such methods of resale, at market
prices prevailing at the time of resale, at prices related to such prevailing
market prices or negotiated prices. Any such resale may be made directly to
purchasers or to or through brokers or dealers who may receive compensation in
the form of commissions or concessions from any such broker-dealer and/or the
purchasers of any such notes. Any broker-dealer that resells notes that were
received by it for its own account pursuant to the exchange offer and any broker
or dealer that participates in a distribution of such notes may be deemed to be
an "underwriter" within the meaning of the Securities Act and any profit on any
such resale of notes and any commissions or concessions received by any such
persons may be deemed to be underwriting compensation under the Securities Act.

     We have agreed to pay all expenses incident to the exchange offer other
than commissions or concessions of any brokers or dealers and will indemnify the
holders of the notes (including any broker-dealers) against certain liabilities,
including liabilities under the Securities Act.

ITEM 22.  UNDERTAKINGS.

     (a) The undersigned registrant hereby undertakes to deliver or cause to be
delivered with the prospectus, to each person to whom the prospectus is sent or
given, the latest annual report to security holders that is incorporated by
reference in the prospectus and furnished pursuant to and meeting the
requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of
1934; and, where interim financial information required to be presented by
Article 2 of Regulation S-X are not set forth in the prospectus, to deliver, or
cause to be delivered to each person to whom the prospectus is sent or given,
the latest quarterly report that is specifically incorporated by reference in
the prospectus to provide such interim financial information.

     (b) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Commission such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the registrant of expenses incurred or
paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

     (c) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11 or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated document by first class mail or other
equally prompt means. This includes information contained in documents filed
subsequent to the effective date of the registration statement through the date
of responding to the request.

     (d) The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

     (e) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in the registration statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
