                                 senior notes will be deemed to accrue from May
                                 15, 2000. 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.

                                 series of Omnipoint notes by the deadline, in
                                 which case we will not make any consent
                                 payments and you may withdraw tendered

                                 Omnipoint notes and revoke consents with
                                 respect thereto at any time before the
                                 expiration of the pertinent 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 offers. The consents that we
                                 are soliciting must be given for all notes that
                                 are tendered for exchange.

Conditions to the Exchange
Offers........................   Our exchange offers are subject to the
                                 condition that they do not violate applicable
                                 law or any applicable interpretation of the
                                 staff of the commission. Our exchange offers
                                 are also subject to the condition that we
                                 receive the consents of a majority of each
                                 series thereof to eliminate the covenants,
                                 restrictive provisions and events of default in
                                 the indentures for the Notes. There is no
                                 guarantee that these conditions will be
                                 satisfied.

Federal Income Tax
Considerations................   The exchange of our new senior notes for
                                 outstanding Omnipoint notes pursuant to our
                                 exchange offers will be a taxable exchange for
                                 federal income tax purposes. In addition, if
                                 the indenture relating to either series of
                                 Omnipoint notes is amended, non-tendering
                                 noteholders of such series will be deemed for
                                 federal income tax purposes to have exchanged
                                 their notes for modified Omnipoint notes, which
                                 may result in the recognition of gain. See
                                 "Certain United States Federal Income Tax
                                 Considerations."


Consent Solicitation..........   We are soliciting consents from the holders of
                                 the outstanding Omnipoint notes to amend the
                                 indentures under which they were issued to
                                 eliminate substantially all the covenants,
                                 restrictive provisions and events of default of
                                 Omnipoint Corporation. We are offering a
                                 consent payment of $20 per $1000 in principal
                                 amount of Omnipoint notes that are tendered for
                                 exchange and not withdrawn and for which
                                 consents are received and not revoked on or
                                 before 5:00 p.m., New York City time, on July
                                 7, 2000 (or such later time as we elect),
                                 provided that we receive consents for at least
                                 a majority of each series of Omnipoint notes.
                                 If we fail to receive consents for a majority
                                 of either series, we will not make consent
                                 payments for any series. Omnipoint noteholders
                                 who hold notes representing approximately 84%
                                 of the Omnipoint Senior Notes and approximately
                                 58% of the Omnipoint Series A Notes have agreed
                                 with VoiceStream to exchange their Omnipoint
                                 notes in the exchange offers. Holders that
                                 tender notes and give consents after the
                                 deadline will not receive the consent payment.
                                 All notes for which consents are given must be
                                 tendered.



Exchange Agent and
Depository....................   The Bank of New York is serving as the exchange
                                 agent in connection with the exchange offers.

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

Consequences If You Do Not
  Tender Your Outstanding
  Omnipoint Corporation
  Notes.......................   Any outstanding Omnipoint notes that are not
                                 tendered to us or are not accepted for exchange
                                 will remain outstanding and will continue to
                                 accrue interest in accordance with and
                                 otherwise be entitled to all the rights and
                                 privilege under their respective indentures. We
                                 are soliciting consents, however, to amend
                                 those indentures to delete substantially all
                                 the covenants, restrictive provisions and
                                 events of default of Omnipoint. If we obtain
                                 the requisite number of consents the indentures
                                 will be so amended and the holders of any
                                 Omnipoint notes that remain outstanding after
                                 the offers have been completed will be without
                                 the protection that the deleted covenants,
                                 restrictive provisions and events of default
                                 gave them. Omnipoint noteholders who hold notes
                                 representing approximately 84% of the Omnipoint
                                 Senior Notes and approximately 58% of the
                                 Omnipoint Series A Notes have agreed with
                                 VoiceStream to exchange their Omnipoint notes
                                 in the exchange offers. For U.S. federal income
                                 tax purposes, a U.S. holder who did not tender
                                 his Omnipoint notes would be treated as having
                                 exchanged such notes for new Omnipoint notes.
                                 See "Certain United States Federal Income Tax
                                 Considerations" beginning on p. 56.

  Ranking.....................   The senior 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 secured,
                                   and will rank equal to such obligations to
                                   the extent that the secured assets do not
                                   satisfy the secured obligations; and

                                 - will rank junior to all existing and future
                                   indebtedness and other liabilities of our
                                   subsidiaries. On May 15, 2000, the aggregate
                                   indebtedness and liabilities of our
                                   subsidiaries was approximately $4.1 billion.

Optional Redemption...........   We have the option to redeem the notes, in
                                 whole or in part, at any time on or after
                                 November 15, 2004 and prior to maturity, at the
                                 redemption prices set forth in this prospectus
                                 under "Description of Our New 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
                                   principal amount of the senior notes on the
                                   redemption date provided that after any such
                                   redemption at least 65% of the aggregate
                                   principal amount of the senior notes remains
                                   outstanding.

                                 - If a change of control and a ratings decline
                                   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
                                   principal amount of the Senior Notes, plus
                                   accrued and unpaid interest and (2) the
                                   present values of the remaining scheduled
                                   payments of principal and interest on the
                                   notes, 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.

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

Change of Control.............   Upon a change of control and a ratings decline,
                                 we will be required to offer to purchase the
                                 notes for a purchase price in cash equal to
                                 101% of the principal amount of the senior
                                 notes, 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.

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

                                 - incur additional indebtedness;

                                 - make investments

                                 - make payments in respect of securities that

                                  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

     As a holding company, we will not hold substantial assets other than our
direct or indirect investments in and advances to our operating subsidiaries.
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 indebtedness and liabilities of our subsidiaries. Our lenders under our
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 May
15, 2000, the total outstanding indebtedness and liabilities of our subsidiaries
was approximately $4.1 billion.

HOLDERS OF OMNIPOINT NOTES THAT EXCHANGE THEM FOR OUR NOTES WILL BECOME
STRUCTURALLY SUBORDINATED TO THE INDEBTEDNESS AND LIABILITIES OF OMNIPOINT, TO
WHICH THEY ARE NOT PRESENTLY SUBORDINATED.

     We are a holding company which owns the capital stock of Omnipoint. Our
ability to make payments in respect of our notes depends upon our receipt of
distributions from Omnipoint and our other subsidiaries. As shareholders of
subsidiaries, our claims are structurally subordinate to the claims of all the
creditors of our subsidiaries.

     Because the Omnipoint notes are obligations of Omnipoint, which are pari
passu with the other obligations of Omnipoint (except for obligations that by
their terms are senior to the Omnipoint notes or obligations that are secured,
to the extent of the assets pledged as security) an Omnipoint noteholder that
exchanges them for our notes will receive notes that are structurally
subordinate to the obligations of Omnipoint, whereas the Omnipoint notes are
pari passu with those obligations. Holders of Omnipoint notes that do not tender
them to us may be left with notes that enjoy the benefit of any restrictive
provision, covenants or events of default.

     Concurrently with making the offers, we are soliciting the consents of the
holders of the Omnipoint notes to amend the related indentures to eliminate all
covenants, restrictive provisions or events of default. If effected, these
amendments will be effective for all Omnipoint notes including those for which
consents were not given. The proposed amendments of each series of the Omnipoint
notes requires only the consent of the majority of that series. A non-tendering
Omnipoint note holder may therefore hold, after the effective date of the
proposed amendments, notes that do not enjoy the benefits of any restrictive
provision, covenants or events of default.

                                        8
<PAGE>   12

AN OMNIPOINT NOTEHOLDER MAY BE SUBJECT TO U.S. FEDERAL INCOME TAX WHETHER OR NOT
IT TENDERS ITS NOTES PURSUANT TO THE OFFERS

     If the proposed amendments to eliminate the covenants, restrictive
provisions and events of default in the outstanding Omnipoint notes indentures
are made, but a holder of outstanding Omnipoint notes does not tender his notes
pursuant to the offers, the non-tendering holder will be treated for U.S.
federal income tax purposes as having exchanged his outstanding Omnipoint notes
for modified Omnipoint notes. As a result, an amount attributable to accrued but
unpaid interest on the non-tendering holder's outstanding Omnipoint notes that
has not previously been recognized would be recognized by the holder as ordinary
interest income. The non-tendering holder may also recognize taxable gain in
such circumstances in an amount equal to the difference between his tax basis in
the outstanding Omnipoint notes and the issue price of the modified Omnipoint
notes. The issue price of the modified Omnipoint notes should equal their fair
market value on the date of the deemed exchange, assuming that the notes are
"publicly traded" as defined in applicable Treasury Regulations.

     The exchange of our new senior notes for outstanding Omnipoint notes will
be a taxable exchange.

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 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 and
our acquisition of Aerial Communications, Inc. on May 4, 2000, we sustained
operating losses of approximately $1.6 billion in 1999, and as of, December 31,
1999, we had an accumulated deficit of $1.1 billion and equity, net of
accumulated deficit, of $10.9 billion. 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.

                                        9
<PAGE>   13

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 May 15, 2000, was approximately $5.6
billion. 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.

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 do 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

                                       10
<PAGE>   14

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
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.

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

                                       11
<PAGE>   15

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 ONE OF OUR SUBSIDIARIES 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 its existing 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, that 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 global
system for mobil communications technology,

                                       12
<PAGE>   16

which we employ. 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 offer to repurchase all or a portion of
our notes at 101% of the principal amount 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 or any other indebtedness that would become payable upon the
occurrence of such change of control. The covenant requiring us to offer to
repurchase the notes will, unless consents of lenders under our credit agreement
are obtained, also 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 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 OFFERS AND CONSENT SOLICITATION


     Subject to the terms and conditions in this prospectus and in the
accompanying Consent and Letter of Transmittal, we will exchange Omnipoint's
outstanding notes that are properly tendered on or before the expiration of the
offers, and not withdrawn, for our registered new notes. The expiration of the
offers is 5:00 p.m., New York City time, on July 21, 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.
During any such extension, all outstanding notes previously tendered will remain
subject to the exchange offer and we may accept them for exchange. 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 Consent and 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 offers described
herein. Our obligation to accept outstanding notes for exchange is subject to
certain conditions as set forth below under "-- Certain Conditions to the
Exchange Offers."

Terms of Exchange Offers for Omnipoint Notes

     We expressly reserve the right to amend or terminate the exchange offers.
We also reserve the right to refuse for exchange any outstanding notes not
theretofore accepted for exchange, if any of the events specified below under
"-- Certain Conditions to the Exchange Offers" occurs. We will give oral or
written notice of any extension, amendment, non-acceptance or termination to you
as promptly as practicable. Any notice with respect to any extension will be
issued by means of press release or other public announcement no later than 9:00
a.m., New York City time, on the next business day after the previously
scheduled expiration date.

                                       14
<PAGE>   18

     Exchange Offers

     For each $1,000 principal amount at maturity of Omnipoint's outstanding
notes accepted for exchange, we will issue to the holder our new senior note
having a principal amount, rounded to the nearest cent, equal to:

     (i) the present value of the earliest redemption price for the applicable
         series of Omnipoint notes displayed in the table on the cover page of
         this prospectus discounted to the date on which the Omnipoint notes are
         accepted for exchange under the exchange offers from the earliest
         redemption date for such series of Omnipoint notes displayed in the
         table on the cover page of this prospectus

         minus

     (ii) $20.00, which is the amount of the consent payment.


     The discount rate which will be used in the above present value calculation
will equal the sum of (x) the yield on the 5 1/2% U.S. Treasury Note due August
2001 plus (y) 100 basis points.



     The exchange agent will calculate the yield on the reference security in
accordance with standard market practice, based on the bid price for such
reference security as of 2:00 p.m., New York City time, on July 19, 2000, the
second business day immediately before the initially scheduled expiration date.
If the offers are extended by more than three business days, then the exchange
agent will calculate the yield based on a bid price for the reference security
on such other day which is the second business day immediately before the
expiration date as extended. The bid price upon which the exchange agent will
calculate the yield on the reference security will be the price as displayed on
the relevant Bloomberg page for the applicable series of Omnipoint notes
contained in the table on the cover page of this prospectus or any recognized
quotation source selected by the exchange agent in its sole discretion if the
Bloomberg government pricing monitor is not available or is clearly in error.


     Consents to certain amendments to the terms of Omnipoint notes are being
solicited as described below under "-- Consent Solicitation." Holders of
Omnipoint notes that tender them in exchange for our new senior notes are
eligible to receive, and will be paid, the consent payment provided that the
notes are validly tendered and not withdrawn before the deadline for receiving
that payment and provided that we receive consents for a majority in principal
amount of both series. See "-- Consent Solicitation" for more information about
the amount and requirements for receiving this payment. Holders are required to
give consents for Omnipoint notes that are tendered for exchange, and notes for
which consents are given must be tendered.

     Interest on our new senior notes will be deemed to accrue from May 15,
2000. 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.

Consent Solicitation

     Concurrently with making the exchange offers, we are soliciting consents
from the holders of the outstanding Omnipoint notes to amend the indentures
under which they were issued to remove substantially all of the covenants,
restrictive provisions and events of default of Omnipoint as more fully
described under the heading "Proposed Amendments to Indentures." The consents of
the holders of at least a majority in principal amount of each series of the
outstanding Omnipoint notes will be required in order to approve the amendments
to the indenture for that series. In the event that

                                       15
<PAGE>   19

the amendments are approved and adopted, they will be binding on all holders of
Omnipoint notes including those who did not give consents. If for any reason the
exchange offers are not completed, the proposed amendments to the Omnipoint note
indentures will not become effective.


     We are offering to pay holders of Omnipoint notes that validly tender them
in exchange for our senior notes and deliver consents with respect thereto at or
before 5:00 p.m., New York time, on July 7, 2000 (or such later time as we
elect) a consent payment equal to $20 per $1000 in principal amount of the
Omnipoint notes so tendered provided that they have not been withdrawn or the
consents with respect thereto revoked, and further provided that consents of the
holders of a majority in principal amount of each series of Omnipoint notes are
received. No consent payment for either series of notes will be paid unless
consent for a majority of both series are received. Holders that tender after
that deadline will not receive the consent payment even if they give consents.
Tendered Omnipoint notes may be withdrawn and consents revoked before the
deadline for receiving the consent payment, but Omnipoint notes may not be
withdrawn and consents may not be revoked at or after that deadline unless we
fail to receive consents for a majority in principal amount of both series of
Omnipoint notes, in which case tendered Omnipoint notes may be withdrawn, and
consents with respect thereto revoked, at any time before the expiration of the
applicable offer. According to the terms of the Consent and Letter of
Transmittal by validly tendering Omnipoint notes in exchange for our senior
notes, a holder is also giving consent with respect thereto. Omnipoint notes
cannot be tendered without giving consent with respect thereto, and they may not
be withdrawn without also revoking the consents. Consents with respect to any
Omnipoint notes cannot be revoked without withdrawing the Omnipoint notes. Notes
for which consents are given must be tendered.


     If we elect to extend the deadline for receiving the consent payment, we
will do so by issuing a press release or other public announcement no later than
9:00 a.m., New York City time, on the next business day thereafter.

Procedures for Tendering Outstanding Notes

     In all cases, issuance of our new notes for outstanding 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 Consent and 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. 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 Consent and Letter of Transmittal against that
participant. THE METHOD OF DELIVERY OF THE OUTSTANDING NOTES, THE CONSENT AND
LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED DOCUMENTS IS AT THE ELECTION AND
RISK OF THE HOLDERS. IF DELIVERY IS MADE 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 ITS PROCEDURES DOES NOT CONSTITUTE
DELIVERY TO THE EXCHANGE AGENT. NO DOCUMENTS SHOULD BE SENT TO US.

     Signatures on a Consent and 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 Consent and 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 Consent
and 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 adequacy of the form of the writing will be
determined by us in our sole discretion.

     If the Consent and 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 Consent and 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 and consents. 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 for which consents have not been
given 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 either before or after
the expiration date.

     Our interpretation of the terms and conditions of the exchange offers
(including the instructions in the Consent and Letter of Transmittal) will be
final and binding on all parties. Unless waived, any defects or irregularities
in connection with tenders of or consents for 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 or consents for 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 or any consent given until
such defects or irregularities have been cured or waived. Any outstanding notes
received by the exchange agent that have not been properly tendered or for which
consents have not been given and as to which the defects or irregularities have
not been cured or waived will be returned without cost by the exchange agent to
the tendering holder unless otherwise provided in the Consent and Letter of
Transmittal, as soon as practicable following the expiration date.

                                       17
<PAGE>   21

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

          (i) terminate the exchange offers;

          (ii) purchase or make offers for any outstanding notes that remain
     outstanding subsequent to the expiration date, and

          (iii) 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
will accept, promptly, all outstanding notes properly tendered and will issue
the new notes in exchange therefor. Also at such time, 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. See "-- Certain Conditions to the Exchange
Offer."

     We are 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 or sell, the unaccepted, non-exchanged or unsold portion of 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 unaccepted, non-exchanged or unsold 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 offers.

Book-Entry Transfer

     The exchange agent 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 offers 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
Consent and 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

     A holder who wishes to tender outstanding notes; but

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

          (ii) the outstanding notes, the Consent and Letter of Transmittal, or
     any other required documents cannot be delivered to the exchange agent on a
     timely basis; or

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

     may effect a tender if:

          (a) the tender is made through an institution eligible to guarantee
     signature on the Consent and Letter of Transmittal; and

          (b) before the expiration date, the exchange agent receives from the
     eligible institution:

        - a properly completed and duly executed Notice of Guaranteed Delivery
          (by facsimile transmission, mail or hand delivery) setting forth the
          name and address of the holder of the outstanding notes;

        - the certificate number or numbers of such outstanding notes and the
          principal amount of outstanding notes tendered, stating that the
          tender is being made thereby, and guaranteeing that 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 Consent and 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 Consent and 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 Consent
          and 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 Consent and Letter of Transmittal,
          are 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 the deadline for receiving the consent payment. See "-- Consent
Solicitation" for how to determine this deadline. If we do not receive consents
for a majority in principal amount of both series of Omnipoint notes, then we
will not pay any consent payments and holders of Omnipoint notes will be
entitled to withdraw them at any time before the expiration of the offers.

                                       19
<PAGE>   23

     To withdraw a tendered note, a written notice of withdrawal must be timely
received by the exchange agent at its address set forth herein. 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 the outstanding note exchanged, and identify the
     outstanding note to be withdrawn (including the certificate number or
     numbers and principal amount of the outstanding note);

          (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; and

          (iv) if a consent to amend the indenture under which the note was
     issued has been given, state that the consent is revoked.

     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.

     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 of 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 offers and no new notes will be
issued or consent payment paid with respect thereto unless the outstanding notes
so withdrawn are validly retendered.

Certain Conditions to the Exchange Offers

     The exchange offers are subject to the condition that they do not violate
applicable law or any applicable interpretation of the staff of the commission.
We cannot assure you that this condition will be satisfied.

     Our exchange offer for Omnipoint Notes is also subject to the condition
that we receive sufficient consents to amend the indentures for the Notes to
eliminate the covenants, restrictive provisions and events of default. Neither
Omnipoint note indenture can be amended without the consent of a majority of the
notes issued and outstanding thereunder.

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

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

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

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

                                       20
<PAGE>   24

     If the waiver would constitute a material change in the exchange offers, 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 offers 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 offers would
otherwise expire during such period.

Fees and Expenses

     We will not make any payments to brokers, dealers or other persons

offers will be paid by us and are estimated to be $500,000.

returned to, a person other than the registered tendering holder will be
responsible for the payment of any applicable transfer tax thereon.

                          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 Bank of New York, 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.

BRIEF DESCRIPTION OF THE NOTES

     The Senior Notes:

     - will be, upon issuance, general obligations of ours;

     - rank equal in right of payment with all of our other senior unsecured
       Indebtedness;

     - 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, which amounted to approximately $4.1 billion at May
       15, 2000.

     - accrue interest from May 15, 2000 at a rate of 10 3/8%, which is payable
       semi-annually commencing 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 redeem all notes at our option upon a Change of Control Triggering
Event.

     The indentures 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;

     - restrictions on Liens;

                                       23
<PAGE>   27

     - 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. 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

SENIOR NOTES

     We will issue Senior Notes with an aggregate principal amount of up to
$500,000,000. The indenture governing the Senior Notes will allow us to issue
additional Senior Notes. These additional Senior Notes will be limited to an
aggregate principal amount of up to $450,000,000. The issuance of any of those
additional Senior Notes will be 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 Senior Notes will be treated as part of the
same class and series as the Senior Notes issued in the offering for purposes of
voting under the indenture governing the Senior Notes. The Senior Notes will
mature on November 15, 2009. We will issue the Senior Notes in denominations of
$1,000 and integral multiples of $1,000.

     Interest on the Senior 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, commencing on November 15, 2000. The Issuers will make each
interest payment to holders of record on the immediately preceding May 1 and
November 1.

     Cash interest will accrue on the Senior Notes from the most recent date to
which interest has been paid. Interest will be computed on the basis of a
360-day year comprised 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

                                       24
<PAGE>   28

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.

PAYING AGENT AND REGISTRAR FOR THE NOTES

     The trustee under the indentures 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 indentures.

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 Senior Notes originally issued 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 Senior Notes
     originally issued remains outstanding immediately after such redemption
     (excluding Senior 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 Senior Notes described under "-- Optional
Redemption -- Change of Control" below, the Senior 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 Senior 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 Senior 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 Senior Notes are to be redeemed at any time, the
trustee under the 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.

                                       25
<PAGE>   29

     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 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
redeem at our option in whole the notes at a redemption price equal to the
greater of:

          (1) 101% of the aggregate principal amount of the Senior 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 Senior Notes is under publicly announced consideration for possible
downgrade by a Rating Agency), the rating of the Senior Notes is decreased by
either Rating Agency by one or more Gradations and the rating by both Rating
Agencies on the Senior 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 indenture 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 indenture 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 indenture 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 pursuant to an Offer to
Purchase. The offer price in any Offer to Purchase will be payable in cash and
will be 101% of the aggregate principal amount of the Senior 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), to
the date of purchase. 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 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 pursuant to the Offer to Purchase;

          (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 indenture 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 to any Offer to Purchase.

     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. 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.

                                       27
<PAGE>   31

     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, 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 indenture 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 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. 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.

                                       28
<PAGE>   32

     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
principal amount 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 Senior
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 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

     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

<PAGE>   33

     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;

     credit in respect of workers' compensation claims or self-insurance,
     provided, however, that upon the drawing of any such letter of credit or

     indemnification, purchase price adjustments or similar obligations, or from
     guarantees of letters of credit, surety bonds or performance bonds securing

     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;

          (11) Indebtedness incurred by us or any of our Restricted Subsidiaries
     under Interest Rate Agreements or Currency Protection Agreements to hedge
     permitted Indebtedness;

     which, together with any other outstanding Indebtedness incurred pursuant
     to this clause (15), does not exceed $50 million at any time outstanding or
     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.

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

     We and our Restricted Subsidiaries will not make any Restricted Payment
unless after giving effect to that Restricted Payment:

          (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
     the indenture is less than or equal to the sum of:

             (a) Cumulative EBITDA less 1.6 times Cumulative Interest Expense;

             (b) 100% of the aggregate Net Cash Proceeds received by us since
        the date of the indentures from the issue or sale of our Equity
        Interests or of our debt securities that have been converted into such
        Capital Stock (other than to a Restricted Subsidiary);

                                       31
<PAGE>   35

             (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:

                (A) payments of interest on debt, dividends, repayment of loans
           or advances, or other transfers or distributions of property, in each
           case to an Issuer or any Restricted Subsidiary from any Person;

                (B) to the extent that any Investment is sold for cash or
           otherwise liquidated or repaid for cash, the after-tax cash return of
           capital with respect to such Investment (less the cost of
           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

             (d) $50 million.

     So long as no Event of Default or event which with notice or lapse of time
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:

          (1) the payment of any dividend within 60 days after declaration
     thereof if at the declaration date such payment would have complied with
     the foregoing provision;

     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

     property and assets of an Issuer.

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
     measured by, its profits, to us or any of our Restricted Subsidiaries or
     pay any Indebtedness or other obligation owed to us or any Restricted
     Subsidiary;

          (2) make any loans or advances to us or any of our Restricted
     Subsidiaries; or

          (3) transfer any of its property or assets to us or any of our
     Restricted Subsidiaries.

     However, the preceding restrictions will not apply to encumbrances or
restrictions existing under or by reason of:

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

          (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;

          (6) applicable law;

          (7) customary provisions restricting subletting or assignment of
     property subject to any lease governing any leasehold interest of any of
     our Restricted Subsidiaries;

          (8) purchase money obligations for property acquired in the ordinary
     course of business that impose restrictions of the type referred to in
     clause (3) of the preceding paragraph;

                                       33
<PAGE>   37

          (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
     "-- 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 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 us or such Restricted
     Subsidiary; and

          (2) such transaction is on terms that are no less favorable to us 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.

                                       34
<PAGE>   38

     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
     Related Person of ours, other than a Wholly Owned Restricted Subsidiary,
     owns any Capital Stock or any option, warrant or other right to purchase
     Capital Stock);

          (2) customary payment of compensation to employees, officers or
     consultants in the ordinary course of business and payment of reasonable
     directors' fees and customary indemnification and insurance arrangements in
     favor of directors, regardless of affiliation with us;

          (3) Restricted Payments that are permitted by the provision of the
     indenture described above under the caption "-- Limitation on Restricted
     Payments";

          (4) payments and other transactions required under or contemplated by
     any agreement in effect on the date of the indenture and disclosed in our
     Form 10/A filed with the SEC on April 13, 1999, our Form 10-Q for the
     quarter ended June 30, 1999, our current reports on Form 8-K filed prior to
     October 15, 1999 (or not required to be disclosed therein pursuant to the
     rules and regulations of the Commission) and Aerial's Form 10-K for the
     fiscal year ended December 31, 1998 and Forms 10-Q and 8-K filed during
     calendar year 1999 prior to November 4, 1999 (or not required to be
     disclosed therein pursuant 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 Subsidiaries 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 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:

          (1) Liens existing in respect of any Indebtedness that exists on the
     date of the indenture or is outstanding or permitted under our Credit
     Facility;

     ours on the assets or Capital Stock of another Wholly Owned Restricted

             (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

             (c) the incurrence of such Indebtedness is otherwise permitted by
        the indenture;

          (4) Liens on property existing immediately prior to the time of
     acquisition thereof (and not incurred in anticipation of the financing of
     such acquisition);

          (5) Liens to secure Indebtedness to extend, renew, refinance or refund
     (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
     indenture described under clause (2) or (7) of "-- Limitation on
     Consolidated Indebtedness";

          (6) Liens securing any Indebtedness of any of the Restricted

     incurred;

          (7) Liens on any Capital Stock of any Unrestricted Subsidiary of ours
     securing Indebtedness of such Subsidiary that is Non-Recourse Indebtedness;

          (8) Liens to secure the performance of statutory obligations, surety
     or appeal bonds, performance bonds or other obligations of a like nature
     incurred in the ordinary course of business (other than obligations for the
     payment of money);

          (9) Liens for taxes, assessments or governmental charges or claims
     that are not yet delinquent or that are being contested in good faith by
     appropriate proceedings promptly instituted and diligently conducted;
     provided that any reserve or other appropriate provision as shall be
     required in conformity with generally accepted accounting principles shall
     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
     with respect thereto are maintained on our books or our Restricted
     Subsidiary, as the case may be, in conformity with generally accepted
     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

     We and our Restricted Subsidiaries will not enter into any Sale and
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).

                                       36
<PAGE>   40

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

          (1) we and our respective Restricted Subsidiaries would be entitled to
     create or incur a Lien to secure Indebtedness pursuant to the provision in
     the indenture described under "-- Limitation on Liens" equal in amount to
     the Attributable Value of the Sale and Leaseback Transaction without
     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 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 indenture,

          (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;
     and

          (4) an Officers' Certificate and an Opinion of Counsel covering such
     conditions shall be delivered to the trustee.

                                       37
<PAGE>   41

EVENTS OF DEFAULT AND REMEDIES

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

          (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 indenture 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 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 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 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 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 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 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
coupons, in denominations of $1,000 and any integral multiple thereof. No
service charge will be made for any transfer or exchange

                                       38
<PAGE>   42

of notes, but we may require payment of a sum sufficient to cover any tax or
other governmental charge payable in connection therewith.

CERTAIN DEFINITIONS

     "Acquired Indebtedness" means, with respect to any specified Person:

          (1) Indebtedness of any other Person existing at the time such other
     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:

          (1) the arithmetic mean of the yields under the heading "Week Ending"
     published in the Statistical Release most recently published prior to the
     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

          (2) 0.50%;

provided, however, that if no maturity set forth under such heading exactly
corresponds to the maturity of such principal, yields for the two published
maturities most closely corresponding to the maturity of such principal will be
calculated as provided immediately above, and the Adjusted Treasury Rate will be
interpolated or extrapolated from such yields on a straight-line basis, rounding
in each of the relevant periods to the nearest month.

     "Affiliate" of any Person means any other Person directly or indirectly
controlling or controlled by or under direct or indirect common control with
such Person. For the purposes of this definition, "control" when used with
respect to any Person means the power to direct the management and policies of
such Person, directly or indirectly; whether through the ownership of voting
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
Subsidiary with, into or to another Person in a transaction in which such
Restricted Subsidiary ceases to be a Restricted Subsidiary, but excluding a
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
Restricted Subsidiary of such Person) of:

          (1) shares of Capital Stock (other than directors' qualifying shares)
     or other ownership interests of a Subsidiary of such Person;

          (2) substantially all of the assets of such Person or any of its
     Subsidiaries representing a division or line of business; or

          (3) other assets or rights of such Person or any of its Subsidiaries.

                                       39
<PAGE>   43

     Notwithstanding the preceding, the following items shall not be deemed to
be Asset Dispositions:

          (1) any single transaction or series of related transactions that (a)
     involves assets having a Fair Market Value of less than $15 million; or (b)
     results in net proceeds to us or any of our respective Restricted
     Subsidiaries of less than $15 million;

          (2) a Restricted Payment that is permitted by the covenant described
     above under the caption "-- Certain Covenants -- Limitation on Restricted
     Payments";

          (3) sales or other dispositions of inventory in the ordinary course of
     business and of receivables;

          (4) substantially simultaneous exchanges by us or any of our
     Restricted Subsidiaries of Telecommunications Assets for other
     Telecommunications Assets, provided that the Telecommunications Assets
     received by us or our Restricted Subsidiary have at least substantially
     equal or greater value to us or our Restricted Subsidiary (as determined by
     the Board of Directors whose good faith determination shall be conclusive
     and evidenced by a Board Resolution);

          (5) any sale or other disposition of any or all the Capital Stock of
     an Unrestricted Subsidiary; or

          (6) any sale or other disposition of Temporary Cash Investments.

Additionally, the contribution of Telecommunications Assets to an Unrestricted
Subsidiary whereby we or our Restricted Subsidiary receives Capital Stock of an
Unrestricted Subsidiary shall be deemed a Restricted Payment only and shall not
be deemed an Asset Disposition.

     "Attributable Value" means, as to any particular lease under which any
Person is at the time liable other than a Capital Lease Obligation, and at any
date as of which the amount thereof is to be determined, the total net amount of
rent required to be paid by such Person under such lease during the initial term

MODIFICATION AND WAIVER

     Modifications and amendments of the indenture may be made by us and the
trustee with the consent of the holders of a majority in aggregate principal
amount of the outstanding notes; provided, however, that no such modification or
amendment may, without the consent of the holder of each note affected thereby:

          (1) change the Stated Maturity of the principal of, or any installment
     of interest on, any note;

          (2) reduce the principal amount of or premium, if any, or interest on
     any note;

          (3) change the place or currency of payment of principal of, or
     premium or interest on any note;

          (4) impair the right to institute suit for the enforcement of any
     payment on or with respect to any note;

          (5) reduce the percentage of aggregate principal amount of notes
     outstanding necessary to amend the indenture;

          (6) reduce the percentage of aggregate principal amount of notes
     outstanding necessary for waiver of compliance with certain provisions of

notes may waive compliance by us with certain restrictive provisions of the
indenture. The holders of a majority in aggregate principal amount of the
outstanding notes may waive any past default under the indenture, except a
default in the payment of principal, premium or interest and certain covenants
and provisions of the indenture which cannot be amended without the consent of
the holder of each outstanding note affected.

DEFEASANCE

     At our option, (1) if applicable, we will be discharged from any and all
obligations in respect of the outstanding notes or (2) if applicable, we may
omit to comply with certain restrictive covenants, and such omission will not be
deemed to be an Event of Default under the indenture 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 the Stated
Maturity. In addition, if we elect to have certain restrictive covenants
discharged under (2) above, the obligations under the indenture other than with
respect to such covenants and the Events of Default other than the Events of
Default relating to such covenants above shall remain in full force and effect.

                                       52
<PAGE>   56

     The trust referred to above may only be established if, among other things:

          (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 and defeasance; 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 indentures and the notes will be governed by and construed in
accordance with the laws of the State of New York.

THE TRUSTEE

     The indentures provide 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 indentures
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 of either
series 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.

     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.

                  PROPOSED AMENDMENTS TO OMNIPOINT INDENTURES

     This section sets forth a brief description of the proposed amendments to
the indentures governing Omnipoint notes for which consents are being sought.
The summaries of provisions of the Indentures set forth below are qualified in
their entirety by reference to the full and complete terms contained in the
respective indentures. Copies of the Indentures are available from us upon
request. See "Where You Can Find More Information" and "Incorporation of
Documents by Reference."

     Holders who tender Omnipoint notes in exchange for our Senior Notes are
obligated to consent to the applicable proposed amendments. Holders of Omnipoint
notes should consider the effect the proposed amendments will have on their
position if they do not tender their Omnipoint notes pursuant to the exchange
offers.

     The proposed amendments to the Omnipoint indentures would, effective as of
the opening of business on the date of our acceptance of all notes validly
tendered pursuant to the exchange offers, eliminate from the indentures
substantially all of the covenants, restrictive provisions and events of default
contained in the indentures, which covenants and events of default are
summarized below.

     The proposed amendments relating to each series of Omnipoint notes will be
effected by the execution of a supplemental indenture relating to that series.
The supplemental indentures for the Omnipoint notes are expected to be executed
promptly after the deadline for the consent payment (see "The Exchange Offers
and Consent Solicitation -- Consent Solicitation") if the requisite consents
have been obtained with respect to both series. If the exchange offer for a
series of Omnipoint notes is terminated or withdrawn, or a series of notes is
not accepted for payment, the supplemental indentures will not become operative.

     The indentures for the Omnipoint notes contain substantially similar
restrictive provisions and covenants and events of default, as noted below. In
addition to the amendments noted below, the proposed amendments would amend or
delete definitions from the indentures when references to such definitions
should be amended or deleted as a result of the deletion of the sections
described below. The proposed amendments would delete in their entirety the
following restrictive provisions, covenants and events of default, and
references thereto, from the Omnipoint indentures:

     Pursuant to the terms of each indenture, the proposed amendments to that
indenture require the written consent of the holders of not less than a majority
in aggregate outstanding principal amount at maturity of the notes issued
pursuant to that indenture.

                         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 Global Note directly through DTC if they are
participants in such system, or indirectly through organizations 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 Indentures 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 applicable 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 participants' 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

                                       55
<PAGE>   59

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 new 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
participants 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 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 is 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 new registered notes for
Omnipoint's outstanding notes. It is provided for general informational purposes
only. It is based on the Internal Revenue Code of 1986, 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
a 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, banks and other financial institutions, broker-dealers and
foreign corporations) that are members of a class of holders subject to special

                                       56
<PAGE>   60

rules. The discussion assumes that the outstanding 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 OF TENDERING OR FAILING TO TENDER 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 notes is a U.S. holder. A U.S. holder is 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 OFFERS TO U.S. HOLDERS

     Exchange of Outstanding Omnipoint Notes for Our New Registered Notes. The
exchange by a U.S. holder of an outstanding Omnipoint note for our new
registered 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 total of the issue price of our new registered note and the consent
payment received by the U.S. holder (less any amount treated as a separate fee
for consenting to the Indenture amendments, as discussed in the next paragraph).
The issue price of our new registered 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.

     We intend to treat the consent payments as additional consideration paid
for the Omnipoint notes. As such, the amount of the consent payment received by
a U.S. holder would be treated in the manner described above for purposes of
computing the U.S. holder's gain or loss on the exchange of its Omnipoint notes.
It is possible, however, that a portion of the amount received by a U.S. holder
pursuant to the offers could be treated by the IRS as a separate fee for
consenting to the amendments to the outstanding Omnipoint notes indentures. The
amount of such separate fee might be more or less than the amount of the consent
payment received by the U.S. holder. The amount, if any, treated as a separate
fee likely would be taxable as ordinary income to the U.S. holder.

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

                                       57
<PAGE>   61

     Persons Who Do Not Tender their Outstanding Omnipoint Notes. If the
amendments to the outstanding Omnipoint notes indentures are made, they would
constitute a significant modification of the outstanding Omnipoint notes for
U.S. federal income tax purposes. In such circumstances, a U.S. holder who did
not tender his Omnipoint notes would be treated as having exchanged such notes
for new Omnipoint notes. It is unclear whether such deemed exchange would result
in a tax-free recapitalization. If it does, an amount attributable to the
non-tendering U.S. holder's accrued but unpaid interest on its outstanding
Omnipoint notes that has not previously been recognized would be recognized by
the holder as ordinary interest income, and no other gain or loss would be
recognized by the holder. If the deemed exchange does not result in a tax-free
recapitalization, an amount attributable to accrued but unpaid interest on the
non-tendering U.S. holder's outstanding Omnipoint notes that has not previously
been recognized would be recognized by the holder as ordinary interest income;
and, in addition, the non-tendering U.S. holder would recognize gain in an
amount equal to the difference between (i) the holder's tax basis in its
outstanding Omnipoint notes (less any basis attributable to accrued but unpaid
interest) and (ii) the issue price of the modified Omnipoint notes (less an
amount attributable to accrued but unpaid interest on the outstanding Notes).
The issue price of the modified Omnipoint notes should equal their fair market
value on the date of the deemed exchange (assuming the modified Omnipoint notes
are "publicly traded" as defined in the applicable Treasury Regulations). Any
gain recognized generally would be capital gain and would be long-term if the
U.S. holder has held the outstanding Omnipoint notes for more than one year at
the time of the deemed exchange. However, a U.S. holder who purchased its
outstanding Omnipoint notes for less than their principal amount may recognized
ordinary income rather than capital gain under the "market discount" rules
discussed under the heading "Market Discount" below, NON-TENDERING U.S. HOLDERS
ARE URGED TO CONSULT THEIR OWN TAX ADVISORS CONCERNING THE POSSIBILITY THAT THEY
WOULD RECOGNIZE GAIN AS A RESULT OF A DEEMED EXCHANGE OF THEIR OUTSTANDING
OMNIPOINT NOTES FOR MODIFIED OMNIPOINT NOTES IN SUCH CIRCUMSTANCES.

     Market Discount. An Omnipoint noteholder that is subject to gain
recognition under any of the rules discussed above and that purchased its
outstanding 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 it has owned its Omnipoint notes. 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. Gain recognized by a U.S. holder in excess of accrued market discount
will generally be capital gain.

     TAX CONSEQUENCES FOR A U.S. HOLDER OF HOLDING OUR NEW REGISTERED NOTES AND
MODIFIED OMNIPOINT NOTES

     Payment of Interest on Our New Registered Notes. Interest paid or payable
on our new registered notes will be taxed to a U.S. holder as ordinary interest
income, generally at the time it is received or accrued, in accordance with such
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.

                                       58
<PAGE>   62

     Possible Original Issue Discount on Our New Registered Notes Received by
Omnipoint Noteholders and on Modified Omnipoint Notes Deemed Received by
Non-Tendering Omnipoint Noteholders. Our new registered notes received by the
Omnipoint noteholders and the modified Omnipoint notes deemed received by the
non-tendering Omnipoint noteholders each will be treated, as issued with
original issue discount ("OID") if, respectively, their stated redemption price
at maturity is greater than their issue price. The amount of OID would be equal
to any such difference between redemption price and issue price. The issue price
of the our new registered notes and the modified Omnipoint notes should be their
fair market value on the date of the exchange or deemed exchange, respectively
(assuming our new notes and the modified Omnipoint notes are "publicly traded"
as defined in the applicable Treasury Regulations). OID 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 New Registered Notes. Upon the sale,
exchange, redemption, retirement at maturity or other disposition of our new
registered notes, 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 that has not previously been recognized, which will
be treated as ordinary interest income) and such U.S. holder's tax basis in the
note. A U.S. holder's tax basis in a new registered VoiceStream note received
pursuant to the offers 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 existing 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."

U.S. FEDERAL INCOME TAXATION OF FOREIGN HOLDERS

     The discussion under this heading, "U.S. Federal Income Taxation of Foreign
Holders," assumes that each holder of notes is a foreign holder. A foreign
holder is 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 OR GAIN IS EFFECTIVELY
CONNECTED WITH THE CONDUCT OF A U.S. TRADE OR BUSINESS IN THE UNITED STATES.

     Sale or Exchange of Outstanding Omnipoint Notes Pursuant to the Offers, and
Sale, Exchange or Retirement of Our New Registered 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 exchange of the
outstanding Omnipoint notes pursuant to the offers, or on the sale, exchange,
redemption, retirement at maturity or other disposition of our new registered
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 fixed place of business" in the United States as defined for
U.S. federal income tax purposes, 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

                                       59
<PAGE>   63

amount received by a foreign holder pursuant to the offers 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 New Registered Notes," substituting Omnipoint for VoiceStream.

     Similar treatment to that set forth in the prior paragraph should apply to
a non-tendering foreign holder of Omnipoint notes that is deemed to exchange
such notes for modified Omnipoint notes. See the discussion above under the
heading "U.S. Federal Income Taxation of U.S. Holders -- Tax Consequences of the
Offers to U.S. Holders -- Persons Who Do Not Tender Their Outstanding Omnipoint
Notes" for a discussion of the deemed exchange that will result in the receipt
of modified Omnipoint notes.

     Payment of Interest on Our New Registered Notes. Under present United
States federal income and estate tax law, and subject to the discussion of
backup withholding below, if you are a foreign holder of our new registered
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

     - 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 note 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, our new registered notes 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 new registered
notes pursuant to the offers,

                                       60
<PAGE>   64

reporting the payment of the offer consideration (except with respect to U.S.
holders that are exempt from the information reporting rules, such as
corporations and tax-exempt organizations).

     Backup Withholding.  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 (which, for an individual,
is his or her social security number) to VoiceStream or its 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 U.S. 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
does not apply to payments made to certain exempt recipients, such as
corporations and tax-exempt organizations. 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 -- Payment of Interest
on Our New Registered 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-United States 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

     We will not receive any proceeds from any sale of notes by broker-dealers
or any other holder of notes. Notes received by broker-dealers for their own
account pursuant to the exchange offers 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 broker-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-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.

     The Company has agreed to pay all expenses incident to the exchange offers
other than sales commissions, discounts or concessions.

                                 LEGAL MATTERS

     Certain legal matters in connection with the exchange offers are being
passed upon for the Company by Friedman Kaplan & Seiler LLP, New York, New York.

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.
