Item 5.     Other Events.
            ------------

     On June 23, 1999, Omnipoint Corporation (the "Company"), VoiceStream
Wireless Corporation, a Washington corporation ("VoiceStream") and VoiceStream
Wireless Holding Corporation, a Delaware corporation ("VHC"), entered into an
Agreement and Plan of Reorganization (the "Reorganization Agreement"), pursuant
to the which the Company will be merged with a newly formed, wholly-owned
subsidiary of VHC (the "Merger").  At the effective time of the Merger, each
share of Omnipoint common stock will be exchanged for the right to receive 0.825
shares of VHS common stock plus $8.00 in cash.  There will be a cash or share
election option available to the Company's shareholders subject to proration.
The Merger is subject to shareholder approval as well as federal, state and
other regulatory approvals.

       In connection with the execution of the Reorganization Agreement, the
Company entered into an agreement (the "Purchase Agreement") with VoiceStream
and Hutchison Telecommunications PCS (USA) Limited, a British Virgin Islands
company ("Hutchison") on June 23, 1999.  Pursuant to the Purchase Agreement, the
Company sold 4,271 shares of its Series A Non-Voting Convertible Preferred Stock
(the "Non-Voting Preferred Stock") to each of VoiceStream and Hutchison for an
aggregate purchase price of approximately $205,000,000.  The Purchase Agreement
also provides for the sale by the Company to these investors of additional
shares of Non-Voting Preferred Stock having an aggregate face value of
approximately $95,000,000 later this year.  Terms of the Non-Voting Preferred
Stock are set forth in the Certificate of Designation, a copy of which has been
filed as an exhibit hereto.

       The summaries of the transactions described above are, in each case,
qualified in their entirety by reference to the Reorganization Agreement and the
Purchase Agreement.  A copy of each of the agreements have been filed as
exhibits hereto.

     SECTION 3.2  Cancellation of Holding Company Capital Stock.  At the
                  ---------------------------------------------

     SECTION 3.3  Conversion of Common Stock.
                  --------------------------

          (a)  (i)  Subject to the provisions of Sections 3.3 and 3.5, at the
Effective Time, each share of VoiceStream Common Stock that is issued and
outstanding immediately prior to the Effective Time shall be converted into one
share of Holding Company Common Stock.  Upon such conversion, all such shares of
VoiceStream Common Stock shall be canceled and cease to exist, and each
certificate theretofore representing any such shares shall, without any action
on the part of the holder thereof, be deemed to represent an equivalent number
of shares of Holding Company Common Stock.

               (ii) Subject to the provisions of Sections 3.3 and 3.5, at the
Effective Time, each share of Omnipoint Common Stock that is issued and
outstanding immediately prior to the Effective Time shall be converted into the
right to receive the Merger Consideration and cash for fractional shares of
Holding Company Common Stock.  Upon such conversion, all such shares of
Omnipoint Common Stock shall be canceled and cease to exist, and each
certificate theretofore representing any such shares shall, without any action
on the part of the holder thereof, be deemed to represent the right to receive
the Merger Consideration.

          (b)  At the Effective Time, each share of VoiceStream Common Stock,
Omnipoint Common Stock or Holding Company Common Stock which is held in the
treasury of VoiceStream, Omnipoint or their respective Subsidiaries (provided,
however, any Omnipoint Common Stock held by VoiceStream or Holding Company shall
not be canceled pursuant to this Section 3.3(b)) immediately prior to the
Effective Time shall, by virtue of the Mergers, cease to be outstanding and
shall be canceled and retired without payment of any consideration therefor.

          (c)  Subject to the provisions of Sections 3.3(g) and (h) and of
Sections 3.5 and 3.7, each share of Omnipoint Common Stock that is issued and
outstanding immediately prior to the Effective Time (excluding any Dissenting
Shares or any share of Omnipoint Common Stock canceled pursuant to Section
3.3(b) or held by Holding Company or VoiceStream) shall be converted, at the
election of the holder thereof in accordance with the procedures set forth
herein, into one of the following:

               (i)  for each such share of Omnipoint Common Stock with respect
     to which an election to receive only Holding Company Common Stock has been
     effectively made and not revoked or lost pursuant to Section 3.3(e) (a
     "Stock Election"), the right to receive the All Stock Number of shares (the
     "Stock Election Exchange Rate") of Holding Company Common Stock (the "Stock
     Election Consideration");

                                       16
<PAGE>

               (ii)  for each such share of Omnipoint Common Stock with respect
     to which an election to receive only cash has been effectively made and not
     revoked or lost pursuant to Section 3.3(e) (a "Cash Election"), the right
     to receive the All Cash Amount in cash, without interest (the "Cash
     Election Consideration"); and

               (iii) for each such share of Omnipoint Common Stock other than
     shares as to which a Stock Election or a Cash Election has been made, the
     right to receive (A) .825 shares (the "Standard Election Exchange Rate") of
     Holding Company Common Stock and (B) $8.00 in cash, ((A) and (B) being
     collectively referred to as the "Standard Election Consideration" and,
     together with the Stock Election Consideration and the Cash Election
     Consideration, the "Merger Consideration").

          (d)  If between the date of this Agreement and the Effective Time the
outstanding shares of VoiceStream Common Stock shall have been changed into a
different number of shares, by reason of any stock dividend, subdivision, split
or combination of shares, the Cash Election Consideration, the Stock Election
Consideration and the Standard Election Consideration, will be correspondingly
adjusted to reflect such stock dividend, subdivision, split or combination of
shares.

          (e)  Each person who, at the Effective Time, is a record holder of
shares of Omnipoint Common Stock (other than holders of shares of Omnipoint
Common Stock to be canceled as set forth in Section 3.3(b)), shall have the
right to submit an Election Form specifying the number of shares of Omnipoint
Common Stock that such person desires to have converted into the right to
receive Holding Company Common Stock pursuant to the Stock Election, the number
of shares of Omnipoint Common Stock that such person desires to have converted
into the right to receive cash pursuant to the Cash Election, or the number of
shares of Omnipoint Common Stock that such person desires to have converted into
the right to receive the Standard Election Consideration, pursuant to the
Standard Election. Any such record holder (including without limitation any such
record holder of Dissenting Shares) who fails properly to submit an Election
Form on or prior to the Election Deadline in accordance with the procedures set
forth in Section 3.4(a) shall be deemed to have made a Standard Election. Each
person who, at the Effective Time, is a record holder of Omnipoint Preferred
Stock, shall be deemed to have made a Standard Election.

          (f)  The aggregate number of shares of Holding Company Common Stock to
be issued to holders of Omnipoint Common Stock in connection with the Omnipoint
Merger or to become subject to issuance upon the conversion of the Omnipoint
Preferred Stock shall equal the product of (x) .825 and (y) the sum of (i) the
total number of shares of Omnipoint Common Stock issued and outstanding
immediately prior to the Effective Time, other than shares to be canceled
pursuant to Section 3.3(b) and shares held by Holding Company or VoiceStream and
(ii) the total number of shares of Omnipoint Common Stock issuable upon
conversion of Omnipoint Preferred Stock outstanding immediately prior to the
Effective Time (the product of (x) and (y) being referred to as the "Holding
Company Share Issuance Number"). If between the date of this

                                       17
<PAGE>

Agreement and the Effective Time the outstanding shares of VoiceStream Common
Stock shall have been changed into a different number of shares, by reason of
any stock dividend, subdivision, split or combination of shares, the Holding
Company Share Issuance Number will be correspondingly adjusted to reflect such
stock dividend, subdivision, split or combination of shares.

          (g)  In the event that the number of shares of Holding Company Common
Stock to be issued to holders of Omnipoint Common Stock in connection with
Omnipoint Merger or to become subject to issuance upon conversion of Omnipoint
Preferred Stock would exceed the Holding Company Share Issuance Number based on
the elections of the holders of Omnipoint Common Stock (together with the
conversion adjustments applicable to the Omnipoint Preferred Stock), (i) all
shares of Omnipoint Common Stock subject to a Cash Election or a Standard
Election will, as elected, be converted into the right to receive the Cash
Election Consideration or the Standard Election Consideration, as the case may
be, and (ii) each share of Omnipoint Common Stock subject to a Stock Election
will be converted into the right to receive (A) a number of shares of Holding
Company Common Stock equal to the Stock Election Exchange Rate times the Stock
Election Proration Factor and (B) an amount of cash equal to (1) the All Cash
Amount multiplied by (2) one minus the Stock Election Proration Factor. The
"Stock Election Proration Factor" means a fraction (x) the numerator of which is
the Holding Company Share Issuance Number minus the aggregate number of shares
of Holding Company Common Stock to be issued in the Omnipoint Merger pursuant to
the Standard Elections or to become subject to issuance upon conversion of
Omnipoint Preferred Stock pursuant to elections corresponding to the Standard
Elections deemed to have been made by holders of Omnipoint Preferred Stock, and
(y) the denominator of which is the number of shares of Holding Company Common
Stock that, but for this paragraph (g), would have been issued to holders of
Omnipoint Common Stock in Transactions pursuant to the Stock Elections.

          (h)  In the event that the number of shares of Holding Company Common
Stock to be issued to holders of Omnipoint Common Stock in connection with the
Omnipoint Merger or to become subject to issuance upon conversion of Omnipoint
Preferred Stock would be less than the Holding Company Share Issuance Number
based on the elections of the holders of Omnipoint Common Stock (together with
the conversion adjustments applicable to the Omnipoint Preferred Stock), (i) all
shares of Omnipoint Common Stock subject to a Stock Election or a Standard
Election will, as elected, be converted into the right to receive the Stock
Election Consideration or the Standard Election Consideration, as the case may
be, and (ii) each share of Omnipoint Common Stock subject to a Cash Election
will be converted into the right to receive (A) a number of shares of Holding
Company Common Stock equal to the Cash Election Proration Factor and (B) an
amount of cash equal to (1) the All Cash Amount multiplied by (2) (x) one minus
(y) the Cash Election Proration Factor divided by the Stock Election Exchange
Rate. The "Cash Election Proration Factor" means a fraction (x) the numerator of
which is the Holding Company Share Issuance Number minus the aggregate number of
shares of Holding Company Common Stock to be issued in the Merger pursuant to
the Stock Elections and the Standard Elections or to become subject to issuance
upon conversion of Omnipoint Preferred

                                       18
<PAGE>

Stock pursuant to elections corresponding to the Standard Elections deemed to
have been made by holders of Omnipoint Preferred Stock, and (y) the denominator
of which is the number of shares of Omnipoint Common Stock subject to the Cash
Elections.

     SECTION 3.4  Surrender and Payment.
                  ---------------------

          (a)  Prior to the Effective Time, Holding Company shall appoint an
agent to be designated by VoiceStream (the "Exchange Agent") for the purpose of
exchanging certificates representing shares of Omnipoint Common Stock (the
"Certificates") for the Merger Consideration. At the Effective Time, Holding
Company will deposit (or cause to be deposited) with the Exchange Agent the
Merger Consideration to be paid in respect of the shares (the "Exchange Fund").
Upon receipt, the Exchange Agent will invest the cash portion of the Exchange
Fund in United States government securities maturing at the Election Deadline or
such other investments as VoiceStream and Omnipoint may mutually agree. Promptly
after the Effective Time, VoiceStream will send, or will cause the Exchange
Agent to send, (A) to each holder of shares of Omnipoint Common Stock, at the
Effective Time, a letter of transmittal and instructions (which shall specify
that the delivery shall be effected, and risk of loss and title shall pass, only
upon proper delivery of the Certificates to the Exchange Agent) for use in such
exchange, and (B) to each holder of shares of Omnipoint Common Stock, an
election form (the "Election Form") providing for such holders to make the
Standard Election, the Cash Election or the Stock Election. Any Standard
Election (other than a deemed Standard Election), Cash Election or Stock
Election shall be validly made only if the Exchange Agent shall have received by
5:00 p.m., New York City time, on a date (the "Election Deadline") to be
mutually agreed upon by VoiceStream and Omnipoint (which date shall not be later
than the twentieth Business Day after the Effective Time), an Election Form
properly completed and executed (with the signature or signatures thereon
guaranteed to the extent required by the Election Form) by such holder
accompanied by such holder's Certificates, or by an appropriate guarantee of
delivery of such Certificates from a member of any registered national
securities exchange or of the National Association of Securities Dealers, Inc.
or a commercial bank or trust company in the United States as set forth in such
Election Form. Any holder of Omnipoint Common Stock who has made an election by
submitting an Election Form to the Exchange Agent may at any time prior to the
Election Deadline change such holder's election by submitting a revised Election
Form, properly completed and signed that is received by the Exchange Agent prior
to the Election Deadline. Any holder of Omnipoint Common Stock may at any time
prior to the Election Deadline revoke his election and withdraw his Certificates
deposited with the Exchange Agent by written notice to the Exchange Agent
received by the close of business on the day prior to the Election Deadline.
VoiceStream shall have the right to make rules (which will be described in the
Election Form), not inconsistent with the terms of this Agreement, governing the
validity of Election Forms and the manner and extent to which Standard
Elections, Cash Election or Stock Elections are to be taken into account in
making the determinations prescribed by Sections 3.3(g) and 3.3(h).

                                       19

          (b)  Upon surrender to the Exchange Agent of its Certificate, together
with a properly completed letter of transmittal, each holder of shares of
Omnipoint Common Stock (the "Omnipoint Holders") will be entitled to receive
promptly after the Election Deadline the Merger Consideration (elected or deemed
elected by it, subject to Sections 3.3(g) and (h)) in respect of the shares of
Omnipoint Common Stock represented by its Certificate. Until so surrendered,
each such Certificate shall represent after the Effective Time, for all
purposes, only the right to receive the Merger Consideration.

          (c)  If any portion of the Merger Consideration is to be paid to a
Person other than the Person in whose name the Certificate so surrendered is
registered, it shall be a condition to such payment that such Certificate shall
be properly endorsed or otherwise be in proper form for transfer and that the
Person requesting such payment shall pay to the Exchange Agent any transfer or
other taxes required as a result of such payment to a Person other than the
registered holder of such Certificate, or establish to the satisfaction of the
Exchange Agent that such tax has been paid or is not payable.

          (d)  After the Effective Time, there shall be no further registration
of transfers of shares of Omnipoint Common Stock. If, after the Effective Time,
Certificates are presented to the Surviving Corporation, they shall be canceled
and exchanged for the Stock Election Consideration provided for, and in
accordance with the procedures set forth, in this Article 3.

          (e)  Any portion of the Exchange Fund made available to the Exchange
Agent pursuant to Section 3.4(a) that remains unclaimed by the Omnipoint
Holders, one year after the Effective Time shall be returned to Holding Company,
upon demand, and any such holder who has not exchanged its shares for the Merger
Consideration in accordance with this Section 3.4 prior to that time shall
thereafter look only to Holding Company for payment of such consideration, any
dividends and distributions in respect of such shares, in each case without any
interest thereon. Notwithstanding the foregoing, Holding Company shall not be
liable to any Omnipoint Holder for any amounts paid to a public official
pursuant to applicable abandoned property, escheat or similar laws. Any amounts
remaining unclaimed by the Omnipoint Holders five years after the Effective Time
(or such earlier date, immediately prior to such time when the amounts would
otherwise escheat to or become property of any Governmental Body) shall become,
to the extent permitted by applicable law, the property of Holding Company free
and clear of any claims or interest of any Person previously entitled thereto.

          (f)  No dividends or other distributions with respect to any Holding
Company Common Stock and no cash payment in lieu of fractional shares as
provided in Section 3.7, shall be paid to the holder of any unsurrendered
Certificates until such Certificates are surrendered as provided in Section
3.4(b). Following such surrender, there shall be paid, without interest, to the
Person in whose name such Holding Company Common Stock has been registered, (i)
at the time of such surrender, (A) in the case of Certificates, the amount of
any cash payable in lieu of fractional shares to which such Person is entitled
pursuant to Section 3.7, and (B) the amount of all dividends or other
distributions with a record date after the Effective Time previously paid or

                                       20
<PAGE>

payable on the date of such surrender, with respect to such Holding Company
Common Stock, and (ii) at the appropriate payment date, the amount of dividends
or other distributions with a record date after the Effective Time but prior to
surrender, and with a payment date subsequent to surrender, payable with respect
to such Holding Company Common Stock.

          (g)  Any portion of the Merger Consideration made available to the
Exchange Agent pursuant to Section 3.4(a) to pay for shares for which appraisal
rights have been perfected shall be returned to Holding Company upon demand.

     SECTION 3.5  Dissenting Shares.  Notwithstanding Section 3.3, Omnipoint
                  -----------------
Common Stock or VoiceStream Common Stock outstanding immediately prior to the
Effective Time and held by a holder who has not voted in favor of the
Transactions and has demanded appraisal for such shares in accordance with
Delaware Law (in the case of Omnipoint) or Washington Law (in the case of
VoiceStream) ("Dissenting Shares") shall not be converted into a right to
receive shares of Holding Company Common Stock (in the case of VoiceStream
Common Stock) or the Merger Consideration (in the case of Omnipoint Common
Stock) unless such holder fails to perfect, withdraws or otherwise loses its
right to appraisal. If, after the Effective Time, such holder fails to perfect,
withdraws or loses its right to appraisal, such shares shall be treated as if
they had been converted as of the Effective Time into a right to receive (i) in
the case of Omnipoint, the Standard Election Consideration and (ii) in the case
of VoiceStream, Holding Company Common Stock.  Omnipoint shall give VoiceStream
prompt notice of any demands received by Omnipoint for appraisal of shares, and
VoiceStream shall have the right to participate in all negotiations and
proceedings with respect to such demands. Except with the prior written consent
of VoiceStream, Omnipoint shall not make any payment with respect to, or settle
or offer to settle, any such demands.

     SECTION 3.6  Options, Warrants and Preferred Stock.  At the Effective Time,
                  -------------------------------------
each option or warrant granted by Omnipoint to purchase shares of Omnipoint
Common Stock which is outstanding and unexercised immediately prior to the
Effective Time shall be assumed by Holding Company and converted into an option
("New Omnipoint Options") or warrant ("New Omnipoint Warrants" and, together
with New Omnipoint Options, "New Omnipoint Convertible Securities") to purchase
shares of Holding Company Common Stock in such amount and at such exercise price
as provided below and otherwise having the same terms and conditions as are in
effect immediately prior to the Effective Time (except to the extent that such
terms, conditions and restrictions may be altered in accordance with their terms
as a result of the Transactions):

               (i)  the number of shares of Holding Company Common Stock to be
     subject to each New Omnipoint Convertible Security shall be equal to the
     product of (x) the number of shares of Omnipoint Common Stock subject to
     the original option or

                                       21
<PAGE>

     warrant and (y) the sum of (1) $8.00 divided by the Closing Price on the
     last day in which shares are traded on NASDAQ immediately preceding the
     Closing Date and (2) .825;

               (ii)  the exercise price per share of Holding Company Common
     Stock under each New Omnipoint Convertible Security shall be equal to (x)
     the exercise price per share of Omnipoint Common Stock under the original
     option or warrant divided by (y) the sum of (1) $8.00 divided by the
     Closing Price on the last day in which shares are traded on NASDAQ
     immediately preceding the Closing Date and (2) .825; and

               (iii) upon each exercise of New Omnipoint Convertible Securities
     by a holder thereof, the aggregate number of shares of Holding Company
     Common Stock subject to a New Option shall be rounded down, if necessary,
     to the nearest whole share and the aggregate exercise price shall be
     rounded up, if necessary, to the nearest cent.

The adjustments provided herein with respect to any options which are "incentive
stock options" (as defined in Section 422 of the Code) shall be effected in a
manner consistent with Section 424(a) of the Code.

          (b)  At the Effective Time, each option or warrant granted by
VoiceStream to purchase shares of VoiceStream Common Stock which is outstanding
and unexercised immediately prior to the Effective Time shall be assumed by
Holding Company and converted into an option ("New VoiceStream Options") or
warrant ("New VoiceStream Warrants" and, together with New VoiceStream Options,
"New VoiceStream Convertible Securities") as follows: (i) the number of shares
of Holding Company Common Stock to be subject to the New VoiceStream Convertible
Securities shall be equal to the the number of shares of VoiceStream Common
Stock subject to the original option or warrant and (ii) the exercise price per
share of VoiceStream Common Stock under the New VoiceStream Convertible
Securities shall be equal to the exercise price per share of VoiceStream Common
Stock under the original option or warrant. The adjustments provided herein with
respect to any options which are "incentive stock options" (as defined in
Section 422 of the Code) shall be effected in a manner consistent with Section
424(a) of the Code.

          (c)  The parties shall take such actions as are necessary for the
assumption of the Omnipoint and VoiceStream options and warrants pursuant to
this Section 3.6 and any obligations to issue Omnipoint Common Stock or
VoiceStream Common Stock under the existing terms of any other plans, agreements
or arrangements of Omnipoint or VoiceStream covering any current or former
employee or director of any member of the Omnipoint Group or any member of the
VoiceStream Group including the reservation, issuance and listing of Holding
Company Common Stock as is necessary to effectuate the transactions contemplated
by this Section 3.6.  Similarly, the parties shall take all actions required to
be taken by it to effectuate such assumption.  The parties shall cause Holding
Company to prepare and file with the SEC a registration statement on Form S-8
(or any other appropriate form) or a post-effective amendment to a registration
statement previously filed under the 1933 Act, with respect to the

                                       22
<PAGE>

shares of Holding Company Common Stock subject to New Omnipoint Options and New
VoiceStream Options and, where applicable, shall use its reasonable best efforts
to have such registration statement declared effective as soon as practicable
following the Effective Time and to maintain the effectiveness of such
registration statement covering such New Omnipoint Options and New VoiceStream
Options (and to maintain the current status of the prospectus contained therein)
for so long as such New Omnipoint Options and New VoiceStream Options remain
outstanding. With respect to those individuals, if any, who, subsequent to the
Effective Time, will be subject to the reporting requirements under Section
16(a) of the 1934 Act, where applicable, the parties shall cause Holding Company
to use all reasonable efforts to administer any New Omnipoint Options and New
VoiceStream Options issued pursuant to this Section 3.6 in a manner that
complies with Rule 16b-3 promulgated under the 1934 Act to the extent that the
Omnipoint or VoiceStream stock options and warrants in respect of which such New
Omnipoint Options and New VoiceStream Options have been issued and complied with
such rule prior to the Transactions.

          (d)  Omnipoint Preferred Stock.
               -------------------------

          From and after the Effective Time, each share of Omnipoint Preferred
Stock, which shall be outstanding as of the Effective Time, shall remain
outstanding and, subject to the terms of the Certificate of Designation of the
Omnipoint Preferred Stock, dated May 1, 1998, shall have the same privileges,
rights and preferences as the Omnipoint Preferred Stock immediately prior to the
Effective Time and, for purposes of Section 4.5(b) of the Certificate of
Designation thereof, all holders of Omnipoint Common Stock will be deemed to
have received pursuant to the Omnipoint Merger the Standard Election
Consideration.

          (e)  Omnipoint Non-Voting Convertible Preferred Stock.
               ------------------------------------------------

          From and after the Effective Time, each share of the Omnipoint Non-
Voting Convertible Preferred Stock (or shares of Common Stock into which they
were converted) which shall be outstanding as of the Effective Time, shall
remain outstanding and, subject to the terms of the Certificate of Designation
of the Omnipoint Non-Voting Convertible Preferred Stock, dated June 23, 1999,
shall have the same privileges, rights and preferences as the Omnipoint Non-
Voting Convertible Preferred Stock.

     SECTION 3.7  Fractional Shares.  No fractional shares of Holding Company
                  -----------------
Common Stock shall be issued in the Mergers. All fractional shares of Holding
Company Common Stock that a holder of shares of Omnipoint Common Stock would
otherwise be entitled to receive as a result of the Mergers shall be aggregated
and if a fractional share results from such aggregation, such holder shall be
entitled to receive, in lieu thereof, an amount in cash without interest
determined by multiplying the Closing Date Market Price by the fraction of a
share of Holding Company Common Stock to which such holder would otherwise have
been entitled.

     SECTION 3.8  Withholding Rights.  Holding Company shall be entitled to
                  ------------------
deduct and withhold from the consideration otherwise payable to any Person
pursuant to this Article 3 such amounts as it is required to deduct and withhold
with respect to the making of such payment under any provision of federal,
state, local or foreign tax law. If Holding Company so withholds amounts, such
amounts shall be treated for all purposes of this Agreement as having been paid
to the Omnipoint Holder, as the case may be, in respect of which Holding Company
made such deduction and withholding.

     SECTION 3.9  Lost Certificates.  If any Certificate is lost, stolen or
                  -----------------
destroyed, upon the making of an affidavit of that fact by the Person claiming
such Certificate to be lost, stolen or destroyed and executing an indemnity
reasonably satisfactory to VoiceStream (and, if required by VoiceStream in the
case of a Certificate representing more than 1,000 shares, the posting by such
Person of a bond, in such reasonable amount as VoiceStream may direct, as
indemnity) indemnifying VoiceStream against any claim that may be made against
VoiceStream with respect to the Certificate, the Exchange Agent will issue, in
exchange for such lost, stolen or destroyed Certificate, (i) the Merger
Consideration to be paid in respect of the shares represented by such
Certificate.  In addition, such Person will be entitled to receive any amounts
payable pursuant to Section 3.4(f).

                  -----------------------------
duly incorporated, validly existing and in good standing under the laws of its
jurisdiction of incorporation and has all corporate powers and authority
required to carry on its business as now conducted and to own, operate and lease
its property.  Omnipoint is duly qualified to do business as a foreign
corporation and is in good standing in each jurisdiction where such
qualification is necessary, except for those jurisdictions where failure to be
so qualified, individually or in the aggregate, has not had and would not be
reasonably expected to have a Omnipoint Material Adverse Effect. Omnipoint has
heretofore delivered or made available to VoiceStream true and complete copies
of the certificate of incorporation and bylaws of Omnipoint as currently in
effect.

     SECTION 4.2  Corporate Authorization.
                  -----------------------

          (a)  The execution, delivery and performance by Omnipoint of this
Agreement and the consummation by Omnipoint of the Transactions are within
Omnipoint's corporate powers and, except for the required approval of
Omnipoint's stockholders of this Agreement and

                                       24
<PAGE>

the Transactions, have been duly authorized by all necessary corporate action on
the part of Omnipoint. This Agreement has been duly and validly executed and
delivered by Omnipoint and, assuming the due and valid authorization, execution
and delivery of this Agreement by VoiceStream and receipt of all required
approvals by Omnipoint's stockholders in connection with the consummation of the
Transactions, constitutes a valid and binding agreement of Omnipoint,
enforceable against it in accordance with its terms except as may be limited by
bankruptcy, insolvency, reorganization, moratorium and other similar laws
affecting creditors' rights generally and by equitable principles of general
applicability.

          (b) At a meeting duly called and held, Omnipoint's Board of Directors
has: (i) determined that this Agreement and the Transactions are advisable and
fair to and in the best interests of Omnipoint's stockholders; (ii) approved and
adopted this Agreement and the Transactions; and (iii) resolved (subject to
Section 8.8(b)) to recommend approval and adoption of this Agreement by its
stockholders. No other corporate proceedings on the part of Omnipoint are
necessary to authorize or approve this Agreement or to consummate the
Transactions (other than, with respect to the Transactions, the approval and
adoption of the Transactions and this Agreement by holders of the shares of
Omnipoint Common Stock to the extent required by Omnipoint's certificate of
incorporation and by applicable Delaware Law).

     SECTION 4.3  Governmental Authorization.
                  --------------------------

          (a)  The execution, delivery and performance by Omnipoint of this
Agreement and the consummation by Omnipoint of the Transactions require no
action by or in respect of, or filing with, any Governmental Body, other than:
(i) the filing of a certificate of merger in accordance with Delaware Law; (ii)
compliance with any applicable requirements of the HSR Act; (iii) compliance
with any applicable requirements of the 1934 Act; (iv) compliance with any
applicable requirements of the Communications Act; (v) compliance with FAA
regulations; (vi) compliance with any applicable requirements of state and local
public utility commissions or similar entities; and (vii) any actions or filing,
the absence of which would not in the aggregate prevent or delay consummation of
the Transactions in any material respect, or otherwise prevent Omnipoint from
performing its obligations under this Agreement in any material respect or would
not in the aggregate have a Omnipoint Material Adverse Effect.

          (b)  Omnipoint and the Omnipoint Subsidiaries have not made any
material misstatements of fact, or omitted to disclose any fact, to any
Government Body or in any report, document or certificate filed therewith, which
misstatements or omissions, individually or in the aggregate, could subject any
material licenses or authorizations to revocation or failure to renew.

     SECTION 4.4  FCC Matters.
                  -----------

          (a) Each member of the Omnipoint Group and each Omnipoint Investment

petition, objection, pleading or proceeding with the FCC or any public service
commission or similar body having jurisdiction or authority over the
communications operations of any member of the Omnipoint Group or any Omnipoint
Investment which questions the validity of or contests any Omnipoint FCC License
or which presents a substantial risk that, if accepted or granted, or concluded
adversely, could result in (as applicable) the revocation, cancellation,
suspension, dismissal, denial or any materially adverse modification of any
Omnipoint FCC License or imposition of any substantial fine or forfeiture
against any member of the Omnipoint Group or any Omnipoint Investment except as
set forth on the Omnipoint Disclosure Statement.

          (f)  No facts are known to any member of the Omnipoint Group which if
known by a Governmental Body of competent jurisdiction would present a
substantial risk that any Omnipoint FCC License could be revoked, canceled,
suspended or materially adversely modified or that any substantial fine or
forfeiture could be imposed against any member of the Omnipoint Group or any
Omnipoint Investment.

     SECTION  4.5 Non-contravention.  The execution, delivery and performance by
                  -----------------
Omnipoint of this Agreement and the consummation by Omnipoint of the
Transactions do not and will not (i) contravene, conflict with, or result in any

Investment; or (iv) result in the creation or imposition of any Lien on any
asset of any member of the Omnipoint Group or any Omnipoint Investment, other
than such exceptions in the case of clauses (ii), (iii) and (iv) as would not
be, individually or in the aggregate, reasonably expected (A) to have a
Omnipoint Material Adverse Effect, (B) materially impair or delay the ability of
Omnipoint to consummate the Transactions or (C) to have a VoiceStream Material

                   -----
Schedules and except as would not have a Omnipoint Material Adverse Effect, (i)
all Omnipoint Tax Returns required to be filed with any taxing authority by, or
with respect to, Omnipoint and the Omnipoint Subsidiaries have been filed in
accordance with all applicable laws or an appropriate extension of time to file
such Omnipoint Tax Returns has been obtained; (ii) Omnipoint and the Omnipoint
Subsidiaries have timely paid all Taxes shown as due and payable on the
Omnipoint Tax Returns that have been so filed, and, as of the time of filing,
the Omnipoint Tax Returns correctly reflected the facts regarding the income,
business, assets, operations, activities and the status of Omnipoint and the
Omnipoint Subsidiaries (other than Taxes which are being contested in good faith
by appropriate proceeding and for which adequate reserves are reflected on the
Omnipoint Balance Sheet); (iii) Omnipoint and the Omnipoint Subsidiaries have
made provision for all Taxes payable by Omnipoint and the Omnipoint Subsidiaries
for which no Omnipoint Tax Return has yet been filed; (iv) the charges, accruals
and reserves for Taxes with respect to Omnipoint and the Omnipoint Subsidiaries
reflected on the Omnipoint Balance Sheet are adequate under GAAP to cover the
Tax liabilities accruing through the date thereof; (v) there is no action, suit,
proceeding, audit or claim now pending or, to the knowledge of Omnipoint,
proposed against or with respect to Omnipoint or any Omnipoint Subsidiary in
respect of any Tax where an adverse determination is reasonably likely; (vi)

examination; and (vii) there are no Liens or encumbrances for Taxes on any of

"Tax Returns" shall mean any return, report, form or similar statement required
to be filed with respect to any Tax (including any attached schedules),

          (b)  To the knowledge of Omnipoint, there is no plan or intention on
the part of any Omnipoint shareholder to sell, exchange, transfer or otherwise
dispose of any stock of Holding Company received in the Transactions, except
that such Omnipoint shareholders as are partnerships for U.S. federal income tax
purposes may distribute such Holding Company stock to one or more of their
partners (other than to a partner which would, immediately after such
distribution, own 5 percent or more of Holding Company's stock, taking into
account such partner's pro rata share of any Holding Company stock held by the
partnership).

     SECTION 4.17  Tax Opinions. There are no facts or circumstances relating to
                   ------------

     SECTION 4.18  Employee Benefit Plans and Labor Matters.
                   ----------------------------------------

          (a)  The Omnipoint Disclosure Schedule contains a true and complete
list, as of the date hereof, of all Omnipoint Employee Plans and all Omnipoint
Benefit Arrangements. Copies of each Omnipoint Employee Plan and each Omnipoint
Benefit Arrangement (and, if applicable, related trust agreements) and all
amendments thereto and written interpretations thereof have been made available
to VoiceStream as of the date hereof or will have been made available to
VoiceStream within thirty days after the date hereof, together with the three
most recent annual reports (Form 5500 including, if applicable, Schedule B

with any Omnipoint Employee Plan.

          (b)  No "accumulated funding deficiency," as defined in Section 412 of
the Code, has been incurred with respect to any Omnipoint Employee Plan subject
to such Section 412, whether or not waived. No "reportable event" within the
meaning of Section 4043 of ERISA for which the reporting requirements have not
been waived, and no event described in Section 4062 or 4063 of ERISA has
occurred in connection with any Omnipoint Employee Plan. Neither Omnipoint nor
to Omnipoint's knowledge any ERISA Affiliate of Omnipoint has (i) engaged in, or
is a successor or parent corporation to an entity that has engaged in, a
transaction described in Sections 4069 or 4212(c) of ERISA or (ii) incurred, or
reasonably expects to incur prior to the Effective Time (A) any liability under
Title IV of ERISA arising in connection with the termination of, or a complete
or partial withdrawal from, any plan covered or previously covered by Title IV
of ERISA or (B) any liability under Section 4971 of the Code that in either case
could become a liability of Omnipoint, any Omnipoint Subsidiary, VoiceStream or

                                       32
<PAGE>

any of their ERISA Affiliates after the Effective Time. If a "complete
withdrawal" by Omnipoint and all of its ERISA Affiliates were to occur as of the
Effective Time with respect to all Multiemployer Plans, neither Omnipoint nor
any Omnipoint Subsidiary would incur any withdrawal liability under Title IV of
ERISA.

          (c)  As of December 31, 1998, the fair market value of the assets of
each Omnipoint Pension Plan (excluding for these purposes any accrued but unpaid
contributions) exceeded the present value of all benefits accrued under such
Omnipoint Pension Plan calculated pursuant to FAS No. 87, "Employers' Accounting
for Pensions."

          (d)  Each Omnipoint Employee Plan that is intended to be qualified
under Section 401(a) of the Code is the subject of a favorable qualification
determination letter issued by the IRS and to Omnipoint's knowledge each such
Omnipoint Employee Plan is so qualified.

          (e)  There is no contract, plan or arrangement (written or otherwise)
covering any employee or former employee of Omnipoint or any Omnipoint
Subsidiary that, individually or collectively, could give rise to the payment of
any amount that would not be deductible pursuant to the terms of Sections 162(m)
or 280G of the Code.

          (f)  As of December 31, 1998, there were no amounts accumulated for
post-retirement benefit obligations under Omnipoint Employee Plans and Omnipoint
Benefit Arrangements as determined in accordance with Statement of Financial
Accounting Standards No. 106.

          (g)  Each Omnipoint Employee Plan and each Omnipoint Benefit
Arrangement has been maintained in material compliance with its terms and with
the requirements prescribed by any and all applicable statutes, orders, rules
and regulations (including any special provisions relating to registration or
qualification where such Plan was intended so to be so registered or qualified)
and has been maintained in good standing with applicable regulatory authorities.

          (h)  No employee or former employee of Omnipoint or any Omnipoint
Subsidiary will become entitled to any bonus, retirement, severance, job
security or similar benefit or enhancement of such benefit (including
acceleration of vesting or exercise of an incentive award) as a result of the
Transactions (either alone or together with any other event).

          (i)  Neither Omnipoint nor any of the Omnipoint Subsidiaries is, or
has been, a party to any collective bargaining agreement or union contract.
Neither Omnipoint nor any of the Omnipoint Subsidiaries is involved in or
threatened with any labor dispute, work stoppage, labor strike, slowdown or
grievance. To the knowledge of Omnipoint, there is no organizing effort or
representation question at issue with respect to any employee of Omnipoint or
any of the Omnipoint Subsidiaries.

     Investment is and has been in compliance with all Environmental Laws and
     all Environmental Permits; and

     Omnipoint Group or any Omnipoint Investment of any kind whatsoever, whether
     accrued, contingent, absolute, determined, determinable or otherwise
     arising under or relating to any Environmental Law and there are no facts,
     conditions, situations or set of circumstances that could reasonably be
     expected to result in or be the basis for any such liability.

          (b)  There have been no environmental assessments, investigations,
studies, audits, tests, reviews or other analyses conducted (collectively,
"Environmental Reports") of which Omnipoint has knowledge in relation to the
current or prior business of any member of the Omnipoint Group or any Omnipoint
Investment or any property or facility now or previously owned or leased by any
member of the Omnipoint Group or any Omnipoint Investment that reveal matters
that, individually or in the aggregate, have had or would reasonably be expected
to have a Omnipoint Material Adverse Effect.

          (c)  For purposes of this Section 4.19, the terms Omnipoint and

Omnipoint Investment own or have a valid license to use each trademark, service
mark, trade name, invention, patent, trade secret, copyright, know-how
(including any registrations or applications for registration of any of the
foregoing) or any other similar type of proprietary intellectual property right
(collectively, the "Omnipoint Intellectual Property") necessary to carry on its
business substantially as currently conducted. No member of the Omnipoint Group
or any Omnipoint Investment has received any notice of infringement of or
conflict with, and to Omnipoint's knowledge, there are no

                                       34
<PAGE>

infringements of or conflicts with, the rights of any Person with respect to the
use of any Omnipoint Intellectual Property that, in either such case,
individually or in the aggregate, have had or would be reasonably expected to
have, a Omnipoint Material Adverse Effect.

     SECTION 4.21  Contracts.  No member of the Omnipoint Group or any Omnipoint
                   ---------
Investment is a party to or bound by (i) any "material contract" (as such term
is defined in Item 601(b)(10) of Regulation S-K of the SEC) or any agreement,
contract or commitment that would be such a "material contract" but for the
exception for contracts entered into in the ordinary course of business, (ii)

commitments of the Omnipoint Group and the Omnipoint Investments is valid and in
full force and effect and (y) neither any member of the Omnipoint Group nor any
Omnipoint Investment has violated any provision of, or committed or failed to
perform any act which, with or without notice, lapse of time, or both, would
constitute a default under the provisions of any such contract, agreement or
commitment.  To the knowledge of Omnipoint, no counterparty to any such
contract, agreement or commitment has violated any provision of, or committed or

Company's respective corporate powers and, except for the required approval of
VoiceStream's stockholders of this Agreement and the Transactions, have been
duly authorized by all necessary corporate action on the part of VoiceStream and
Holding Company. This Agreement has been duly and validly executed and delivered
by VoiceStream and Holding Company and, assuming the due and valid
authorization, execution and delivery of this Agreement by Omnipoint and receipt

consummation of the Transactions, constitutes a valid and binding agreement of
VoiceStream and Holding Company, enforceable against it in accordance with its
terms except as may be limited by bankruptcy, insolvency, reorganization,
moratorium and other similar laws affecting creditors' rights generally and by
equitable principles of general applicability.

          (b)  VoiceStream and the VoiceStream Subsidiaries have not made any
material  misstatements of fact, or omitted to disclose any fact, to any
Governmental Body, which misstatements or omissions, individually or in the

commission or similar body having jurisdiction or authority over the
communications operations of any member of the VoiceStream Group or any

that in either case could become a liability of VoiceStream, any VoiceStream
Subsidiary, Omnipoint or any of their ERISA Affiliates after the Effective Time.
If a "complete withdrawal" by VoiceStream and all of its ERISA Affiliates were

Accounting for Pensions."

          (d)  Each VoiceStream Employee Plan that is intended to be qualified
under Section 401(a) of the Code is the subject of a favorable qualification
determination letter issued by the IRS and to VoiceStream's knowledge each such
VoiceStream Employee Plan is so qualified.

          (e)  There is no contract, plan or arrangement (written or otherwise)
covering any employee or former employee of VoiceStream or any VoiceStream
Subsidiary that, individually or collectively, could give rise to the payment of
any amount that would not be deductible pursuant to the terms of Sections 162(m)
or 280G of the Code.

and regulations (including any special provisions relating to registration or
qualification where such Plan was intended so to be so registered or qualified)
and has been maintained in good standing with applicable regulatory authorities.

          (h)  No employee or former employee of VoiceStream or any VoiceStream
Subsidiary will become entitled to any bonus, retirement, severance, job
security or similar benefit or enhancement of such benefit (including
acceleration of vesting or exercise of an incentive award) as a result of the
Transactions (either alone or together with any other event).

          (i)  Neither VoiceStream nor any of the VoiceStream Subsidiaries is,
or has been, a party to any collective bargaining agreement or union contract.
Neither VoiceStream nor any of the VoiceStream Subsidiaries is involved in or
threatened with any labor dispute, work stoppage, labor strike, slowdown or
grievance. To the knowledge of VoiceStream, there is no organizing effort or
representation question at issue with respect to any employee of VoiceStream or

any limitation imposed from time to time under applicable law. Without limiting
the generality of the foregoing, the Indemnified Losses shall include reasonable
costs of prosecuting a claim under this Section 7.2(a). Holding Company shall
periodically advance or reimburse each Indemnified Person for all reasonable
fees and expenses of counsel constituting Indemnified Losses as such fees and

promptly repay to Holding Company the amount of any such reimbursement if it

provide officers' and directors' liability insurance in respect of acts or
omissions occurring prior to the Effective Time (including, without limitation,
for acts or omissions occurring in connection with this Agreement and the

policies have been made available by Omnipoint to VoiceStream and by VoiceStream
to Omnipoint); provided that if the aggregate annual premiums for such insurance
during such period shall exceed 200% of the per annum rate of premium paid by
Omnipoint (with respect to the liability insurance policies of the officers and
directors of Omnipoint) or VoiceStream (with respect to the liability insurance
policies of the officers and directors of VoiceStream) as of the date hereof for
such insurance, then Holding Company shall provide a policy with the best
coverage as shall then be available at 200% of such rate.

consummation of

                                       58

the Transactions and are intended to benefit, and shall be enforceable by, each
Indemnified Person.

Common Stock underlying the securities to be issued pursuant to Section 3.6) to
be approved for listing on NASDAQ, subject to official notice of issuance, and
(ii) the securities of Omnipoint to be de-listed from NASDAQ following the

     SECTION 7.4    Holding Company Board of Directors.  Immediately prior to

               (i)  honor the terms of all Omnipoint Employee Plans and
     Omnipoint Benefit Arrangements as in effect on the date hereof (or as
     amended with the prior consent of VoiceStream) and to pay the benefits
     required under such terms of such plans and arrangements, in each case
     subject to Section 7.5(c); and

               (ii) until December 31, 2001 (the "Benefits Maintenance Period"),
     with respect to employees of Omnipoint or any of Omnipoint Subsidiaries at
     the Effective Time ("Transferred Employees"), provide a level of employee
     benefits and aggregate compensation which is substantially comparable in
     the aggregate to the level of employee benefits and aggregate compensation
     provided by Omnipoint and Omnipoint Subsidiaries as of the Effective Time
     (other than the benefits provided under any severance or termination
     benefit plans and arrangements of Omnipoint or any Omnipoint Subsidiary).

          (b) If Transferred Employees are included in any VoiceStream Benefit
Arrangement or VoiceStream Employee Plan, including without limitation, any plan
or arrangement providing vacation benefits, the Transferred Employees shall
receive credit for service prior to the Effective Time with Omnipoint and the
Omnipoint Subsidiaries and their

                                       59
<PAGE>

predecessors to the same extent such service was counted under similar Omnipoint
Employee Plans and Omnipoint Benefit Arrangements for purposes of determining
eligibility to participate, vesting [and the level of benefits provided]. If
Transferred Employees or their dependents are included in any medical, dental or
health plan other than the plan or plans they participated in at the Effective
Time (a "Successor Plan"), any such Successor Plan shall (i) waive all
limitations as to pre-existing conditions, exclusions and waiting periods,
except to the extent such limitations, exclusions or waiting periods were
applicable to such employees or dependents under any corresponding Omnipoint
Employee Plan at the Effective Time, and (ii) provide each such employee or
dependent with credit for any copayments and deductibles paid prior to the date
of inclusion in the Successor Plan in satisfying any applicable deductible or
out-of-pocket requirements under such Successor Plan.

          (c) Notwithstanding any of the above, nothing contained herein shall
be construed as requiring VoiceStream or any VoiceStream Subsidiary to continue
any specific Employee Plan or Benefit Arrangement or to continue the employment
of any specific person, provided, however, that any changes that VoiceStream or
any VoiceStream Subsidiary may make to any such Employee Plan or Benefit
Arrangement are permitted by the terms of the applicable Employee Plan or
Benefit Arrangement under any applicable Law.

representatives to cooperate with Omnipoint's investigation. Any investigation
pursuant to this Section 7.6 shall be conducted in such manner as not to

                    -----------------------------------------

          (a) Holding Company will not issue any stock as compensation for
services in connection with the Transactions or take any other action which may

Code.

          (b) Holding Company will retain the VoiceStream and Omnipoint shares
following the Transactions and Holding Company will not liquidate Omnipoint or
VoiceStream or otherwise dispose of such shares unless it obtains an opinion of
counsel to the effect that such liquidation or disposition will not cause the
Transactions to fail to qualify as an exchange under Section 351 of the Code.

                                       60

                    -------------------

statements therein not misleading.  Holding Company shall use its best efforts
to have the Affiliate Registration Statement declared effective as soon as
practicable after the Closing Date and shall keep the Affiliate Registration
Statement effective subject to appropriate "blackout" periods and other
exceptions and limitations as the Board of Directors of Holding Company

thereunder, or (iii) all Affiliate Shares may be sold without registration under
the 1933 Act.

parties will use its reasonable best efforts to promptly (i) take, or cause to
be taken, all actions and to do, or cause to be done, all things necessary,
proper or advisable under applicable laws and regulations to consummate the

and other documents, and (ii) obtain and maintain all approvals, consents,
registrations, permits, authorizations and other confirmations required to be

Governmental Bodies) that are necessary, proper or advisable to consummate the
Transactions.  In connection with the foregoing, Omnipoint will cooperate with
and assist VoiceStream, and, with respect to matters that are within Omnipoint's
power or control, will use its best efforts to promptly (i) take, or cause to be
taken, all actions and to do, or cause to be

                                       61

preparing and filing as promptly as practicable all documentation to effect all
necessary filings, notices, petitions, statements, registrations, submissions of
information, applications and other documents, (ii) obtain and maintain all
approvals, consents, registrations, permits, authorizations and other
confirmations required to be obtained from any third party that are necessary,
proper or advisable to consummate the Transactions; provided, however, no member
of the VoiceStream Group or any VoiceStream Subsidiary shall be required to
divest or hold separate or otherwise take or commit to take any action that
limits its freedom of action with respect to (or Holding Company's ability to

VoiceStream Group's business, product lines, or assets of the Omnipoint Group,

pursuant to Section 10.1, VoiceStream and Omnipoint shall jointly request one or
more extensions of the consummation period of such grant.  No party hereto shall

antitrust laws for the consummation of the Transactions and any other
transactions contemplated hereby.

Communications Act, the Parties shall (i) as promptly as possible and in any
event within 15 days after the date hereof file with any other applicable

fact or omit to state a material fact required to be stated therein or necessary

to the extent that any such untrue statement of a material fact or omission to
state a material fact was made by VoiceStream in reliance upon and in conformity
with written information concerning Omnipoint furnished to VoiceStream by
Omnipoint specifically for use in the Proxy Statement/Prospectus. Omnipoint
agrees that the written information concerning Omnipoint provided by it for
inclusion in the Proxy Statement/Prospectus and each amendment or supplement
thereto, at the time of mailing thereof and at the time of the respective

written information concerning Omnipoint provided by Omnipoint for inclusion in
the Form S-4 or any amendment or supplement thereto, at the time it is filed or

                Designations, Powers, Preferences, Limitations,
                      Restrictions, and Relative Rights of

                SERIES A NON-VOTING CONVERTIBLE PREFERRED STOCK

                  ___________________________________________

                         Pursuant to Section 151 of the
                General Corporation Law of the State of Delaware
                  ____________________________________________

          OMNIPOINT CORPORATION, a Delaware corporation (the "Issuer"), does
hereby certify that pursuant to authority conferred upon the Board of Directors
of the Issuer by its Amended and Restated Certificate of Incorporation and
pursuant to the provisions of Section 151 of the General Corporation Law of the
State of Delaware, the following resolution establishing the Issuer's Series A
Non-Voting Convertible Preferred Stock was duly adopted by the Board of
Directors, on June 21, 1999, and such resolution remains in full force and
effect.  Certain capitalized terms used herein are defined in Article 8.

          RESOLVED, that pursuant to the authority expressly granted to and
          vested in the Board of Directors of the Corporation by the provisions
          of Section Fourth (B) of the Amended and Restated Certificate of
          Incorporation, as amended from time to time (the "Certificate of
          Incorporation"), and pursuant to Section 151(g) of the General
          Corporation Laws of the State of Delaware, there be established from
          the 10,000,000 shares of Preferred Stock, $0.01 par value, of the
          Corporation, authorized to be issued pursuant to the Certificate of
          Incorporation, a series of Preferred Stock, consisting of 12,500
          shares of Series A Non-Voting Convertible Preferred Stock, having the
          designations, powers, preferences and relative and other special
          rights and the qualifications, limitations and restrictions as
          follows:

     1.  Designation and Number of Shares.  The series will be known as the
"Series A Non-Voting Convertible Preferred Stock" (the "Preferred Stock"), and
will be a series consisting of 12,500 shares of the authorized but unissued
preferred stock of the Issuer.

     2.  Dividends.  Each share of the Preferred Stock will be deemed to be, and
treated for all purposes relating to the declaration and payment of dividends
as, the number of shares of Common Stock into which each share of the Preferred
Stock is then convertible at the then current Conversion Price.
<PAGE>

     3.  Ranking.  (a)  Outstanding shares of the Preferred Stock will, with
respect to distributions upon the liquidation, winding up or dissolution of the
Issuer, rank on parity with the outstanding shares of the Issuer's 7% Cumulative
Convertible Preferred Stock, $0.01 par value per share.

          (b)  Except as otherwise expressly provided herein, the Issuer may
amend the Certificate of Incorporation to authorize or establish one or more
additional classes or series of preferred stock or other Capital Stock,
authorize, approve and file certificates of designation relating thereto, and
issue without restriction from time to time, any classes or series thereof.

     4.  Conversion.

          4.1   (a)  All or any portion of the outstanding shares of the
Preferred Stock may be convertible at any time into Common Stock at the option
of the holder thereof into a number of shares of Common Stock equal to the
aggregate Liquidation Preference of the shares of Preferred Stock being
converted divided by the Conversion Price (subject to paragraph 4.1(b) hereof),
provided that at the time of such conversion any applicable waiting period under
the HSR Act applicable thereto shall have expired or been terminated.

          (b)  In the event of an Issuer Breach, the aggregate Liquidation
Preference of the Preferred Stock that may, in accordance with the regulations
and rulings, if any, of the Federal Communications Commission, be converted into
Common Stock at a price per share equal to the then current Reduced Conversion
Price will be so converted.  The aggregate Liquidation Preference of the shares
of Preferred Stock that remain outstanding after such conversion at the Reduced
Conversion Price will be exchanged for one or more notes (with an aggregate
initial principal amount equal to the amount of such remaining balance)
representing unsecured debt of the Issuer (the "Conversion Notes").  The terms
and provisions of the Conversion Notes shall be set forth in the Securities
Purchase Agreement.

          (c)  The following provisions and procedures will apply to and govern
the conversion process set forth in Section 4.1(a) or Section 4.1(b):

                  (i)   Immediately prior to the close of business on the
Conversion Date, each Holder of Preferred Stock will be deemed to be the Holder
of record of Common Stock issuable upon conversion of such Holder's Preferred
Stock notwithstanding that the share register of the Issuer may then be closed
or that certificates representing such Common Stock will not then be actually
delivered to or as directed by such Person;

                  (ii)  As a pre-condition to delivery by the Transfer Agent of
certificates representing the shares of Common Stock and/or Conversion Notes, as
appropriate, properly issuable to each such Holder in connection therewith, each
Holder of Preferred Stock must promptly surrender to the Issuer or the Transfer
Agent certificates representing the shares of Preferred Stock so converted (if
not previously delivered), duly endorsed in blank or accompanied by proper
instruments of transfer;

                                      -2-
<PAGE>

                  (iii) Issuance or delivery of certificates for Common Stock
and/or Conversion Notes, as appropriate, upon the conversion of shares of the
Preferred Stock will be made without charge to the Holders of shares of the
Preferred Stock for such certificates and/or Conversion Notes, or for any tax in
respect of the issuance or delivery of such certificates and/or Conversion Notes
or the securities represented thereby, and such certificates will be issued or
delivered in the respective names of, or in such names as may be directed in
writing by, the Holders of the shares of Preferred Stock. Notwithstanding
anything in the preceding sentence to the contrary, the Issuer will not be
required to pay any tax that may be payable in respect of any transfer involved
in the issuance and delivery of any such certificate or note in a name other
than that of the registered Holder of the shares of Preferred Stock, and the
Issuer will not be required to issue or deliver any such certificate and/or
Conversion Note unless or until the Person or Persons requesting the issuance or
delivery thereof have paid to the Issuer the amount of such tax or have
established to the reasonable satisfaction of the Issuer that such tax has been
paid; and

                  (iv)  If the Conversion Date is not a Business Day, then such
conversion right will be deemed exercised on the next Business Day.

                  (v)   On the Conversion Date, all rights with respect to the
outstanding shares of Preferred Stock, including the rights, if any, to receive
notices, will terminate, except the rights of Holders thereof (or their
respective designees or assignees) to:

                          (1)  receive certificates for the number of shares of
Common Stock and/or Conversion Notes, as appropriate, into which such shares of
Preferred Stock have been converted following compliance by each Holder with the
provisions of Section 4.1(c)(ii); and

                          (2)  exercise the rights to which they are entitled as
Holders of Common Stock and/or Conversion Notes, as appropriate.

          4.2  The Conversion Price and the Reduced Conversion Price will be
subject to adjustment as follows:

                  (a)  If the Issuer at any time subdivides or combines the
outstanding shares of Common Stock, or makes a dividend or other distribution on
the Common Stock in shares of Common Stock, the Conversion Price and the Reduced
Conversion Price will be proportionately decreased in the event of a share
subdivision, dividend or other distribution, or proportionately increased in the
event of a share combination.

                  (b)  Whenever the Conversion Price and the Reduced Conversion
Price are adjusted as herein provided, the Issuer will cause a copy of a notice
to be sent by first-class mail, postage prepaid, to each registered Holder of
the Preferred Stock showing in reasonable detail the facts requiring such
adjustment and identifying the then current Conversion Price and Reduced
Conversion Price after giving effect to such adjustment.

                  (c)  Irrespective of any adjustments to the Conversion Price
and the Reduced Conversion Price or the number or kind of shares purchasable
upon conversion of shares of the Preferred Stock, certificates representing
shares of the Preferred Stock theretofore

                                      -3-
<PAGE>

or thereafter issued may continue to express the same Conversion Price or
Reduced Conversion Price and number and kind of shares previously stated in the
certificates for shares of the Preferred Stock.

                  (d)  The Issuer may, at its election, retain a firm of
independent public accountants of recognized standing, which may be the firm
regularly retained by the Issuer, selected by the Board of Directors of the
Issuer or its officers, to make any computation required under this Section 4.2.
A certification by such firm will be conclusive evidence of the accuracy and
correctness of any computation made under this Section 4.2.


          4.3  Notwithstanding anything to the contrary contained in this
Certificate of Designation, no Conversion Price or Reduced Conversion Price
adjustment will be made as a result of the issuance of Common Stock on
conversion of the Preferred Stock.

          4.4  (a)  Any event described in (i) or (ii), below, will be
hereinafter referred to as a "Transaction."

                          (i)  any capital reorganization or reclassification or
other change of outstanding shares of Common Stock (other than a change in par
value, or from par value to no par value, or from no par value to par value), or

                          (ii) any sale, transfer or other conveyance to another
Person of all or substantially all of the assets of the Issuer computed on a
consolidated basis (other than the sale, transfer, assignment or distribution of
shares of Capital Stock or assets to a Subsidiary and other than pursuant to the
transactions contemplated by the Agreement), then the adjustment described in
Section 4.4 (b) will be made.

               (b) Each share of Preferred Stock outstanding at the time of any
Transaction will automatically and without further action by an Person become
convertible only into the kind and amount of shares of stock or other securities
(of the Issuer or another issuer) or property or cash receivable upon such
Transaction by a Holder of the number of shares of Common Stock into which such
share of Preferred Stock could have been converted immediately prior to such
Transaction, after giving effect to any adjustment event.

               (c) The provisions of this Section 4.4 contain the sole rights of
Holders of Preferred Stock in connection with any Transaction and such Holders
will have no separate vote thereon.

          4.5   The Issuer will at all times reserve and keep available for
issuance upon the conversion of the Preferred Stock, such number of its
authorized but unissued shares of Common Stock as will from time to time be
sufficient to permit the conversion of all outstanding shares of Preferred
Stock, and will take all action required to increase the authorized number of
shares of Common Stock if at any time there are insufficient authorized,
unissued shares of Common Stock to permit such reservation or to permit the
conversion of all outstanding shares of Preferred Stock.

                                      -4-

     5.  Liquidation Preference.

          5.1  Upon any voluntary or involuntary liquidation, dissolution or
winding up of the Issuer (each, a "Liquidation Event"), Holders of the Preferred
Stock will be entitled to be paid, out of assets of the Issuer available for
distribution the Liquidation Preference per share of the Preferred Stock plus an
amount in cash equal to all unpaid dividends thereon, if any, to the date fixed
for liquidation, dissolution or winding up, before any distribution is made on
the Common Stock or any other Capital Stock ranking below the Preferred Stock in
connection with any Liquidation Event.

          5.2    If, upon any voluntary or involuntary liquidation, dissolution
or winding-up of the Issuer, the amounts payable with respect to the Preferred
Stock and all other Parity Securities are not paid in full, the Holders of the
Preferred Stock and the Parity Securities will share equally and ratably in any
distribution of assets of the Issuer in proportion to the full Liquidation
Preference and unpaid dividends, if any, to which each is entitled.

          5.3  After payment of the full amount of the Liquidation Preference
and any unpaid dividends to which they are entitled, the Holders of shares of
the Preferred Stock will have no right or claim to any of the remaining assets
of the Issuer.

          5.4  Neither the sale, conveyance, exchange or transfer (for cash,
shares of stock, securities or other consideration) of all or substantially all
of the property or business of the Issuer (other than in connection with the
winding up of its business), nor the merger or consolidation of the Issuer with
or into any other corporation, nor a Transaction will be deemed to be a
dissolution, liquidation, or winding up, voluntary or involuntary, of the
Issuer.

     6.  Voting Rights.

          6.1  Holders of the Preferred Stock have no voting rights, except as
provided by law or as expressly set forth in Section 6.2.

          6.2  The affirmative vote or consent of the Holders of at least 51% of
the outstanding Preferred Stock will be required for amendments to the
Certificate of Incorporation that would adversely affect the rights of Holders
of the Preferred Stock.  In such cases, each share of Preferred Stock will be
entitled to one vote.

          6.3  Except as set forth in this Certificate of Designation, the
creation, authorization or issuance of any shares of Parity Securities or any
other Capital Stock ranking below the Preferred Stock in connection with any
Liquidation Event, or an increase or decrease in the amount of authorized
Capital Stock of any class, including any preferred stock, does not and will not
require the consent of the Holders of the Preferred Stock and does not and will
not be deemed to affect adversely the rights, preferences, privileges or voting
rights of Holders of shares of the Preferred Stock.

     7.  Amendment, Supplement and Waiver.  Without the consent of any Holder or
Holders of the Preferred Stock, the Issuer may amend or supplement this
Certificate of Designation to

                                      -5-

 II  PURCHASE AND SALE OF PREFERRED STOCK

     SECTION 2.1    Initial Closing.  Subject to the terms and conditions of
                    ---------------
this Agreement, at the Initial Closing, Issuer will issue, sell and deliver
4,271 shares of Preferred Stock to VoiceStream and 4,271 shares of Preferred
Stock to HPCS (collectively, the "Initial Shares") for a purchase price of
$24,000 per share payable to Issuer on the Initial Closing Date.

     SECTION 2.2    Subsequent Closing.  Subject to the terms and conditions of
                    ------------------
this Agreement, at the Subsequent Closing, Issuer will issue, sell and deliver
1,979 shares of Preferred Stock to VoiceStream and 1,979 shares of Preferred
Stock to HPCS (collectively, the "Subsequent Shares"), for a purchase price of
$24,000 per share payable to Issuer on the Subsequent Closing Date.

     SECTION 2.3    Use of Proceeds.  Issuer shall use the proceeds from the
                    ---------------
sale of the (a) Initial Closing Shares, for the purposes set forth on Schedule
2.3(a) and (b) the Subsequent Closing Shares, for the purposes set forth on
Schedule 2.3(b).

     SECTION 2.4    Terms of Preferred Stock.  The Preferred Stock is
                    ------------------------
convertible at any time or from time to time into Common Stock at the conversion
price of $24 per share of Common Stock; provided, however, that the conversion
price shall be reduced to $18.50 per share of Common Stock (the "Reduced
Conversion Price") if the mergers contemplated by the Reorganization Agreement
are not consummated and are terminated by reason of (i) a breach by Issuer of
its covenants, agreements or obligations under the Reorganization Agreement or
(ii) any representation or warranty of Issuer under the Reorganization Agreement
being untrue in any material respect; provided, however, that conversion may not
                                      --------  -------
occur until any applicable waiting period under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended, relating to the transactions contemplated
hereby shall have expired or been terminated.  In the event that the conversion
of the Preferred Stock into Common Stock occurs at the Reduced Conversion Price,
the number of shares of Preferred Stock so converted shall not exceed that
number of shares which may be converted into Common Stock in accordance with the
regulations and rulings of the Federal Communications Commission and applicable
law.  In the event that, after giving effect to such conversion at the Reduced
Conversion Price, there are shares of Preferred Stock remaining which could not
be so converted (such remaining amount, the "Remaining Preferred Shares"), the
Remaining Preferred Shares shall be redeemed by Issuer through the issuance of
indebtedness to the Purchasers.  Such indebtedness shall be senior unsecured
debt of Issuer, shall bear interest at an annual rate of 7%, and shall mature on
September 30, 2006 (the "Maturity").  There shall be no payments of interest or
principal on such debt until the Maturity.  Such debt shall not contain any
covenants (other than the obligation to repay in accordance with the terms
thereof) and shall only be accelerated upon a bankruptcy or insolvency event of
Issuer or upon acceleration of Issuer's high yield indebtedness.

     SECTION 3.1    Time and Place of Initial Closing.  Subject to the
                    ---------------------------------
conditions set forth in Section 9.1, the closing of the transactions
contemplated by Section 2.1 (the "Initial Closing") shall take place at the
offices of Friedman Kaplan & Seiler LLP, 875 Third Avenue, New York, New York,
at 10:00 a.m. local time on the date hereof (the "Initial Closing Date").  At
the Initial Closing, Issuer shall deliver to Purchasers duly executed and issued
stock certificates evidencing the Initial Shares purchased thereby against
payment of the purchase price therefor by wire transfer of immediately available

price shall be paid on the Initial Closing Date and one-half of which shall be
paid on the first Business Day following the Initial Closing Date.

     SECTION 3.2    Time and Place of Subsequent Closing.  The closing of the
                    ------------------------------------
transactions contemplated by Section 2.2 (the "Subsequent Closing") shall take
place at the offices of Friedman Kaplan & Seiler LLP, 875 Third Avenue, New
York, New York, at 10:00 a.m. local time on October 1, 1999, provided that the
conditions set forth in Section 9.3 are satisfied, or such later date on which
the conditions set forth in Section 9.3 are satisfied (such earlier date, the
"Subsequent Closing Date") or waived by Purchasers or at such other place and/or
time and/or on such other date as the parties may agree; provided, however, that
                                                         --------  -------
if the Subsequent Closing Date has not occurred on or before December 31, 1999,
Purchasers' obligations hereunder may be terminated by Purchasers.  In the event
the Reorganization Agreement has been terminated as a result of a breach of such
Reorganization Agreement by Issuer, Purchasers shall have the right but not the
obligation to acquire the Subsequent Shares.  At the Subsequent Closing, Issuer
shall deliver to Purchasers duly executed and issued stock certificates
evidencing the Subsequent Shares purchased thereby against payment of the
purchase price therefor by wire transfer of immediately available funds to the
account specified therefor by Issuer.


 IV  REPRESENTATIONS AND WARRANTIES OF ISSUER

     SECTION 4.1    Representations and Warranties of Issuer.
                    ----------------------------------------

          (a) Incorporation of Representations and Warranties in Reorganization
              -----------------------------------------------------------------
Agreement.  The representations and warranties of Issuer set forth in Section 4
- ---------
of the Reorganization Agreement (together with the Disclosure Schedule) are
hereby incorporated herein by reference, and are hereby made by Issuer to
Purchasers as of the date hereof and the Initial Closing Date, in their entirety
with the same force and effect.

          (b) Additional Representations and Warranties.  Issuer hereby
              -----------------------------------------
represents and warrants to Purchasers as of the date hereof, the Initial Closing
Date and the Subsequent Closing Date that the shares of Preferred Stock being
issued to Purchasers hereunder, when issued and paid for pursuant to the terms
of this Agreement, will be duly authorized, validly issued, fully paid and

                                       4
<PAGE>

nonassessable, and will be free and clear of any Liens, and shall not be subject
to any preemptive rights of the holders of any other class or series of the
capital stock of Issuer.  The shares of Common Stock issued upon conversion of
the Preferred Stock, when issued pursuant to the terms thereof, will be validly
issued, fully paid and nonassessable, and will be free and clear of any Liens.

          (c) Power and Authority; No Violation.  The Issuer has full power and
              ---------------------------------
authority to execute, deliver and perform its obligations under this Agreement
and to consummate the transactions contemplated hereby.  This Agreement and all
transactions contemplated hereby have been duly and validly authorized by all
necessary action on the part of Issuer and this Agreement constitutes a legal,
valid and binding obligation of Issuer enforceable in accordance with its terms
except as such enforceability may be limited by bankruptcy, insolvency,
moratorium or other similar laws affecting or relating to enforcement of
creditors' rights generally.  Neither the execution, delivery or performance of
this Agreement nor the consummation of the transactions contemplated hereby by
Issuer will, with or without the giving of notice or the passage of time, or
both, (i) conflict with, result in a default or loss of rights (or give rise to
any right of termination, cancellation or acceleration) under, or result in the
creation of any Lien, pursuant to (A) any provision of the certificate of
incorporation, by-laws, stockholders agreements or other constituent documents
of Issuer; (B) any material note, bond, indenture, mortgage, deed of trust,
contract, agreement, lease or other instrument or obligation to which Issuer is
a party or by which Issuer or its property may be bound or affected; or (C) any
law, order, judgment, ordinance, rule, regulation or decree to which Issuer is a
party or by which it or its property is bound or affected; or (ii) give rise to
any right of first refusal or similar right with respect to any interest, or any
properties or assets, of Issuer.   No permit, consent, approval, authorization,
qualification or registration of, or declaration to or filing with any
governmental or regulatory authority or agency or third party is required to be
obtained or made by Issuer in connection with the execution and delivery of this
Agreement or the consummation of the transactions contemplated hereby or thereby
in order to (A) render this Agreement or the transactions contemplated hereby or
thereby valid and effective and (B) enable Issuer to sell the Purchased Shares
(including shares of Common Stock into which such shares may be converted).

          (d) Legal Matters.  There is no claim, legal action, counterclaim,
              -------------
suit, arbitration, governmental investigation or other legal, administrative or
tax proceeding, nor any order, decree or judgment, in progress or pending, or to
the knowledge of Issuer threatened, against or relating to the right of Issuer
to perform its obligations under this Agreement, nor does Issuer know or have
reason to be aware of any basis for the same. There is outstanding no order,
writ, injunction, judgment or decree of any court, governmental agency or
arbitration tribunal applicable to Issuer or binding upon it or its property
which would individually or in the aggregate impair in any material respect the
performance of the obligations of Issuer hereunder or the consummation of the
transactions contemplated by this Agreement other than orders or decrees
involving the wireless telephone industry in general.

          (e) Truth and Correctness.  No representation or warranty by Issuer in
              ---------------------
this Agreement contains or will contain any untrue statement of a material fact
or omits or will omit to

                                       5
<PAGE>

state a material fact necessary to make the statements contained herein or
therein, in light of the circumstances under which such statements are made, not
misleading.

          (f) Investment Company Act.  Issuer is not an "investment company"
              ----------------------
within the meaning of the Investment Company Act of 1940, as amended.

          (g) No Brokers.  Except as set forth on Schedule 4.1(g) hereto, no
              ----------
agent, broker, investment banker, person or firm is or will be entitled to any
broker's or finder's fee or any other commission or similar fee directly or
indirectly in connection with the transactions contemplated by this Agreement
based in any way on any arrangements, agreements or understandings made by or on
behalf of Issuer or an Affiliate thereof, and Issuer hereby agrees to indemnify
the Investor and agrees to hold harmless the Investor against and in respect of
any claims for brokerage and other commissions relating to such transactions
based in any way on any arrangements, agreements or understandings made by or on
behalf of Issuer or an Affiliate thereof.

          (h) Reports and Financial Statements.  The Issuer has filed all
              --------------------------------
reports required to be filed with the SEC since January 1, 1998 (collectively,
including all exhibits thereto, the "SEC Reports").  None of such SEC Reports,
as of their respective dates (as amended through the date hereof), contained any
untrue statement of a material fact or omitted to state a material fact required
to be stated therein or necessary to make the statements therein, in light of
the circumstances under which they were made, not misleading.  Each of the
financial statements (including the related notes) included in the SEC Reports
presents fairly, in all material respects, the consolidated financial position
and consolidated results of operations and cash flows of Issuer and its
subsidiaries as of the respective dates or for the respective periods set forth
therein, all in conformity with generally accepted accounting principles
consistently applied during the periods involved, subject, in the case of the
unaudited interim financial statements, to normal year-end adjustments and any
other adjustments described therein.  All such SEC Reports, as of their
respective dates (as amended through the date hereof), complied in all material
respects with the requirements of the Exchange Act.

 V   REPRESENTATIONS AND WARRANTIES OF PURCHASERS

          Each Purchaser, as to itself only, hereby represents and warrants to
Issuer (as of the date hereof, the Initial Closing Date and the Subsequent
Closing Date):

     SECTION 5.1    Authorization.  It has the full power and authority to enter
                    -------------
into this Agreement and to perform all of its obligations hereunder.  The
execution, delivery and performance of this Agreement by it have been duly
authorized by all necessary corporate action, and this Agreement constitutes a
valid and binding obligation of it enforceable against it in accordance with its
terms except as may be limited by bankruptcy, insolvency, reorganization,
moratorium and other similar laws affecting creditors' rights generally and by
equitable principles of general applicability. The execution, delivery and
performance of this Agreement by it do not (a) violate any provision

                                       6
<PAGE>

of its certificate of incorporation, by-laws or other constituent documents, (b)
conflict with or constitute a default under any material agreement, indenture or
instrument to which it is a party or by which it or its property is bound or (c)
violate any statute or order of any court or Governmental Body applicable to it,
except in each case set forth in clauses (b) or (c) which would not reasonably
be expected to have a material adverse effect on its business taken as a whole
or the transactions contemplated hereby.

 VII REGISTRATIONS RIGHTS

     SECTION 7.1    Demand Registrations.
                    --------------------

          (a) Right to Demand Registration.  At any time on and after the
              ----------------------------
earliest to occur of (i) the termination of the Reorganization Agreement, (ii)
any breach by Issuer of its obligations under this Agreement or the
Reorganization Agreement and (iii) June 30, 2000, the holders of not less than
twenty (20%) percent of the Registrable Securities, as the case may be
(collectively, the "Offerors"), may request registration under the Securities
Act of all or part of their Registrable Securities.  Within seven days after
receipt of any such request, Issuer will give written notice of such request to
all other holders of securities of the Issuer entitled to notice of or the right
to participate in such registrations ("Other Registrable Securities") and will
include in such registration all Other Registrable Securities with respect to
which Issuer has received written requests for inclusion therein within 20 days
after the receipt of Issuer's notice.  A registration requested pursuant to this
Section 7.1(a) is referred to herein as a "Demand Registration".  A Demanding
Stockholder may make a written request for a Demand Registration in accordance
with the foregoing in respect of equity securities of Issuer that it intends to
convert into shares of Common Stock upon the effectiveness of the Registration
Statement prepared in connection with such demand, and Issuer shall fulfill its
obligations under this Section 7.1(a) in a manner that permits such Demanding
Stockholder to exercise its conversion rights in respect of such equity
securities and substantially contemporaneously sell the shares of Common Stock
issuable upon such conversion under such Registration Statement.

          A request pursuant to this Section shall state the number of
Registrable Securities requested to be registered, the intended method of
disposition thereof and the jurisdictions in which registration is desired.  In
connection with any registration subject to this Section 7.1(a), the holders of
Registrable Securities included in such registration shall enter into such
underwriting, lock-up and other agreements, and shall execute and complete such
questionnaires and other documents, as are customary in a primary offering.

          (b) Number of Demand Registrations.  The holders of Registrable
              ------------------------------
Securities will be entitled to request four (4) Demand Registrations, and Issuer
will pay all Registration Expenses in connection therewith.  A registration will
not constitute a Demand Registration (i) until it has become effective, (ii if
the Offerors for such registration are not able to sell at least 80% of the
Registrable Securities requested to be included in such registration, or (ii if
after it has become effective, the offering of Registrable Securities pursuant
to such registration is interfered with by any stop order, injunction or other
order or requirement of the SEC or other governmental agency or court.

                                       8
<PAGE>

          (c) Priority on Demand Registrations.  Issuer will not include in any
              --------------------------------
Demand Registration any securities which are not Registrable Securities or Other
Registrable Securities without the written consent of the Offerors not to be
unreasonably withheld (and the Offerors may not withhold their written consent
if the Demand Registration is an underwritten offering and the managing
underwriters advise Issuer and the Offerors in writing that in their opinion the
number of Registrable Securities and other securities requested to be included
therein does not exceed the number of securities which can be sold in such
offering without materially adversely affecting such sale).  If Other
Registrable Securities are permitted to be included in a Demand Registration
which is an underwritten offering and the managing underwriters advise Issuer in
writing that in their opinion the number of Registrable Securities and Other
Registrable Securities requested to be included exceeds the number of securities
which can be sold in such offering without materially adversely affecting such
sale, Issuer will include in such registration prior to the inclusion of any
securities which are not Registrable Securities the number of Registrable
Securities requested to be included which in the opinion of such managing
underwriters can be sold, pro rata among the respective holders of such
Registrable Securities on the basis of the amount of such securities owned.

          (d) Restrictions on Demand Registrations.  Issuer may postpone for up
              ------------------------------------
to three months in the aggregate during any twelve month period any filing or
the effectiveness of any registration statement for a Demand Registration if the
Board of Directors of Issuer determines (and Issuer so certifies by written
notice to the Offerors) that such Demand Registration might reasonably be
expected to have an adverse effect on any proposal or plan by Issuer or any of
its Subsidiaries to engage in any material corporate transaction; provided that
                                                                  --------
in such event, the Offerors initiating the request for such Demand Registration
will be entitled to withdraw such request.

          (e) Selection of Underwriters.  In the case of a Demand Registration,
              -------------------------
the Offerors will have the right to select the investment banker(s) and
manager(s) to administer the offering, subject to Issuer's approval which will
not be unreasonably withheld.

     SECTION 7.2    Piggyback Registrations.
                    -----------------------

          (a) Right to Piggyback Registrations.  Whenever Issuer proposes to
              --------------------------------
register any of its Capital Stock under the Securities Act, Issuer will give
prompt written notice (in any event within ten business days after its receipt
of notice of any exercise of other demand registration rights) to the holders of
Registrable Securities of its intention to effect such a registration and will
use its best efforts to include in such registration all Registrable Securities
with respect to which Issuer has received written requests for inclusion therein
within 20 days after the receipt of Issuer's notice by such holders (or at such
later time if Issuer and the process of such registration will not be materially
prejudiced thereby).  A request pursuant to this Section 7.2(a) shall state the
number of Registrable Securities requested to be registered.  In connection with
any registration subject to this Section 7.2(a), the holders of Registrable
Securities included in such registration shall enter into such underwriting,
lock-up and other agreements, and shall execute and complete such questionnaires

                                       9
<PAGE>

and other documents, as are customary in a secondary offering.  Issuer shall
have the right to terminate or withdraw any registration initiated by it under
this Section 7.2(a) prior to the effectiveness of such registration whether or
not any holders of Registrable Securities have elected to include any securities
in such registration.  All registrations requested pursuant to this Section
7.2(a) are referred to herein as "Piggyback Registrations".  No registration
effected under this Section 7.2 shall relieve Issuer of its obligation to effect
a Demand Registration pursuant to Section 7.1.

          (b) Priority on Primary Registrations.  If a Piggyback Registration is
              ---------------------------------
an underwritten primary registration on behalf of Issuer, and the managing
underwriters advise Issuer in writing that in their opinion the number of
securities requested to be included in such registration exceeds the number
which can be sold without materially adversely affecting such offering, Issuer
will include in such registration (regardless of whether any holder initially
requested such registration) (i) first, the securities Issuer proposes to sell
and (ii second, Registrable Securities and all Other Registrable Securities
requested to be included in such registration, pro rata among the holders
thereof on the basis of the number of shares owned by such holders.

          (c) Priority on Secondary Registrations.  If a Piggyback Registration
              -----------------------------------
is an underwritten secondary registration on behalf of holders of Issuer's
securities (and in which Issuer is not issuing any securities under such
registration), and the managing underwriters advise Issuer in writing that in
their opinion the number of securities requested to be included in such
registration exceeds the number which can be sold without materially adversely
affecting such offering, Issuer will include in such registration (i) first, the
securities requested to be included in such registration by the holder or
holders who requested such registration (such holders being entitled to
participate in accordance with the relative priorities, if any, as may exist
among them) and (ii second, Registrable Securities and all Other Registrable
Securities requested to be included in such registration, pro rata among the
holders thereof on the basis of the number of shares owned by such holders.

          (d) Selection of Underwriters.  In the case of a Piggyback
              -------------------------
Registration which is a primary registration on behalf of Issuer, Issuer will
have the right to select any investment banker(s) and manager(s) of nationally
recognized standing to administer the offering.

     SECTION 7.3    No Inconsistent Agreement.  Any right given by Issuer to any
                    -------------------------
holder or prospective holder of Issuer's securities in connection with the
registration of securities shall be conditioned such that it shall be consistent
with the rights of the holders of Registrable Securities provided in this
Agreement and shall not materially adversely affect the right of the holders of
Registrable Securities to participate in Piggyback Registrations in the manner
set forth in this Agreement.  Notwithstanding anything to the contrary set forth
in this Article VII, the parties hereto agree to promptly incorporate the
provisions of this Article VII into the existing Amended and Restated
Registration Rights Agreement, dated June 29, 1995, to which Issuer is a party,
it being understood that such incorporation shall not in any material way impair
the registration rights set forth in this Article VII.

<PAGE>

     SECTION 7.4    Lockup Agreement.
                    ----------------

          (a) Each Purchaser agrees, and prior to transferring Registrable
Securities will cause its proposed transferee to agree, if requested by Issuer
and the managing underwriters of Registrable Securities, not to sell or
otherwise transfer or dispose of (other than by private placement) any other
Registrable Securities (or other securities) of Issuer ten days prior to or
during the 90-day period following the effective date of a registration
statement of Issuer filed under the Securities Act, provided that all officers,
                                                    --------
directors and stockholders owning four percent (4%) or more (on a fully diluted
basis, treating all outstanding options, rights and warrants to acquire equity
securities of Issuer as fully exercised, and treating all securities convertible
into or exchangeable for equity securities of Issuer as fully converted or
exchanged) of Issuer's equity securities shall enter into similar agreements.
Such agreement shall be in writing in a form satisfactory to Issuer and such
underwriter.  Issuer may impose stop transfer instructions with respect to the
shares (or securities) subject to the foregoing restriction until the end of
said 90-day period.

          (b) Issuer agrees (i) not to effect any public sale or distribution of
its equity securities, or any securities convertible into or exchangeable or
exercisable for such securities, during the ten days prior to and during the 90-
day period beginning on the effective date of any underwritten Demand
Registration or any underwritten Piggyback Registration (except as part of such
underwritten registration or pursuant to registrations on Form S-4 or Form S-8
or any successor form or forms not available for registering capital stock for
sale to the public at large), unless all of the Registrable Securities included
in such Registration have been sold and (ii to cause each holder of at least 25%
of its equity securities acquired from Issuer (other than a holder that acquired
such securities in a registered public offering or in open market transactions,
unless such holder owned beneficially five percent or more of Issuer's equity
securities prior to such public offering) to agree not to effect any public sale
or distribution of any such securities during such period (except as part of
such underwritten registration, if otherwise permitted), unless all of the
Registrable Securities included in such Registration have been sold.

     SECTION 7.5    Termination of Certain Rights and Obligations .
                    ---------------------------------------------
Notwithstanding the foregoing provisions of this Agreement, the rights to
registration pursuant to Sections 7.1 and 7.2, the obligations of Purchasers
pursuant to Section 7.4(a), and the obligations of Issuer and the holders of 25%
or more of its equity securities pursuant to Section 7.4(b) shall terminate as
to any particular Registrable Securities that shall have been (a) sold in a
registered public offering, (b) sold through a broker, dealer or underwriter in
a public distribution or a public securities transaction in which the transferee
receives a certificate without a securities legend or (c) sold or distributed
pursuant to Rule 144.

     SECTION 7.6    Registration Procedures.  Whenever the Offerors have
                    -----------------------
requested that any Registrable Securities be registered pursuant to this
Agreement, Issuer will use its best efforts to

                                      11
<PAGE>

accordance with the intended method of disposition thereof, and pursuant thereto
Issuer will expeditiously:

          (a) prepare and file with the SEC a registration statement with
respect to such Registrable Securities and use its best efforts to cause such
registration statement to become and remain effective for a period of not less
than three months; provided that before filing a registration statement or
                   --------
prospectus or any amendments or supplements thereto, Issuer will furnish to the
counsel selected by the Offerors requesting such registration statement copies
of all such documents proposed to be filed, which documents will be subject to
the review of such counsel before such filing is made, and Issuer will comply
with any reasonable request made by such counsel to make changes to the extent
such documents do not comply in all material respects with the Securities Act;

          (b) prepare and file with the SEC such amendments (including post-
effective amendments) and supplements to such registration statement and the
prospectus used in connection therewith as may be necessary to keep such
registration statement effective for a period of not less than three months and
to comply with the provisions of the Securities Act with respect to the
disposition of all securities covered by such registration statement during such
period in accordance with the intended methods of disposition by the sellers
thereof set forth in such registration statement;

          (c) furnish to each seller of Registrable Securities such number of
conformed copies of such registration statement, each amendment and supplement
thereto (in each case including all exhibits), the prospectus included in such
registration statement (including each preliminary prospectus) and such other
customary documents as such seller may reasonably request in order to facilitate
the disposition of the Registrable Securities owned by such seller;

          (d) use its best efforts to register or qualify such Registrable
Securities under such other securities or blue sky laws of such jurisdictions as
any seller reasonably requests and do any and all other acts and things which
may be reasonably necessary or advisable to enable such seller to consummate the
disposition in such jurisdictions of the Registrable Securities owned by such
seller (provided that Issuer will not be required to (i) qualify generally to do
business in any jurisdiction where it would not otherwise be required to qualify
but for this subparagraph, (ii subject itself to taxation in any such
jurisdiction, or (ii consent to service of process except as required by the
securities or blue sky laws in any such jurisdiction);

a prospectus relating thereto is required to be delivered under the Securities
Act of Issuer's becoming aware that the prospectus included in such registration
statement, as then in effect, contains an untrue statement of a material fact or
omits any material fact necessary to make the statements therein not misleading
in light of the circumstances under which they were made, and, at the written
request of any such seller, Issuer will prepare a supplement or amendment to
such prospectus so that, as thereafter delivered to the purchasers of such
Registrable Securities, such prospectus will not contain

                                      12
<PAGE>

an untrue statement of a material fact or omit to state any material fact
necessary to make the statements therein not misleading in light of the
circumstances under which they were made;

          (f) use its best efforts to cause all such Registrable Securities
covered by such registration statement to be listed or quoted on the principal
securities exchange or national automated quotation system on which similar
securities issued by Issuer are then listed or quoted or, if not then listed or
quoted, use its best efforts to cause such Registrable Securities to be listed
on a national securities exchange or quoted on a national automated quotation
system;

          (g) provide a transfer agent and registrar for all such Registrable
Securities covered by such registration statement not later than the effective
date of such registration statement;

          (h) in the event the offering is an underwritten offering, use its
best efforts to obtain a "cold comfort" letter from the independent public
accountants for Issuer in customary form and covering such matters of the type
customarily covered by such letters;

          (i) enter into such customary agreements (including underwriting
agreements in customary form) and take all such other actions as the holders of
a majority of the Registrable Securities being sold or the underwriters, if any,
reasonably request in order to expedite or facilitate the disposition of such
Registrable Securities; and

          (j) upon execution and delivery of such customary confidentiality
agreements as Issuer shall reasonably request, make available for inspection by
any seller of Registrable Securities covered by such registration statement, any
underwriter participating in any disposition pursuant to such registration
statement, and any attorney, accountant or other agent retained by any such
seller or underwriter, all pertinent financial and other records, pertinent
corporate documents and properties of Issuer, and cause Issuer's officers,
directors, employees and independent accountants to supply all information
reasonably requested by any such seller, underwriter, attorney, accountant or
agent in connection with such registration statement.

          Issuer will make generally available to the holders of Registrable
Securities an earnings statement (which need not be audited) for the twelve
months beginning after the effective date of a registration statement as soon as
reasonably practicable after the end of such period, which earnings statement
shall satisfy Section 11(a) of the Securities Act.

          Issuer will, at all times after Issuer has filed a registration
statement with the SEC pursuant to the requirements of either the Securities Act
or the Exchange Act, file all reports required to be filed by it under the
Securities Act and the Exchange Act and the rules and regulations adopted by the
SEC thereunder, and take such further action as any holder or holders of

     to which a Purchaser Indemnitee may become subject under the Securities
     Act, common law or otherwise, insofar as such losses, claims, damages,
     liabilities or expenses arise out of or are caused by any untrue or alleged
     untrue statement of material fact contained in any registration statement,
     prospectus or preliminary prospectus or any amendment thereof or supplement
     thereto relating to such securities or any omission or alleged omission of
     a material fact required to be stated therein or necessary to make the
     statements therein not misleading in light of the circumstances under which
     they were made, except insofar as the same are caused by or contained in
     any information furnished in writing to Issuer by such holder expressly for
     use therein or by such holder's failure to deliver a copy of the
     registration statement or prospectus or any amendments or supplements
     thereto after Issuer has furnished such holder with a sufficient number of
     copies of the same;

               (ii)  against all losses, claims, damages, liabilities and
     expenses to the extent of the aggregate amount paid in settlement of any

received by such holder from the sale of Registrable Securities pursuant to such
registration statement, prospectus or preliminary prospectus.

          (c) Any Person entitled to indemnification hereunder will (i) give
prompt written notice to the indemnifying party of any claim with respect to
which it seeks indemnification and (ii unless in such indemnified party's
reasonable judgment a conflict of interest between such indemnified and
indemnifying parties may exist with respect to such claim, permit such
indemnifying party to assume the defense of such claim with counsel reasonably
satisfactory to the indemnified party.  If such defense is assumed, the
indemnifying party will not be subject to any liability for any settlement made
by the indemnified party without its consent (but such consent will not be
unreasonably withheld).  An indemnifying party who is not entitled to, or elects
not to, assume the defense of a claim will not be obligated to pay the fees and
expenses of more than one counsel for all parties indemnified hereunder by such
indemnifying party with respect to such claim, unless in the reasonable judgment
of any indemnified party a conflict of interest may exist between such
indemnified party and any other of such indemnified parties with respect to such
claim in which case such indemnified party shall have the right to employ one
counsel.  Failure to give prompt written notice shall not release the
indemnifying party from its obligations hereunder, except to the extent that the
indemnifying party is actually prejudiced by such failure to give notice.

          (d) The indemnification provided for under this Agreement will remain
in full force and effect regardless of any investigation made by or on behalf of
the indemnified party or any officer, director or controlling Person of such
indemnified party and will survive the transfer of securities.  Issuer also
agrees to make such provisions as are reasonably requested by any indemnified
party for contribution to such party in the event Issuer's indemnification is
unavailable for any reason.

     SECTION 7.9    Contribution.  In order to provide for just and equitable
                    ------------
contribution in circumstances under which the indemnity contemplated by Section
7.8 is for any reason not available, the parties required to indemnify by the
terms thereof shall contribute to the aggregate losses, claims, damages,
liabilities and expenses of the nature contemplated by such indemnity

                                      16
<PAGE>

agreement incurred by any Purchaser Indemnitee, any Company Indemnitee and one
or more of the underwriters, except to the extent that contribution is not
permitted under Section 11(f) of the Securities Act. In determining the amounts
which the respective parties shall contribute, there shall be considered the
parties' relative fault concerning the matter with respect to which the claim
was asserted, knowledge and access to information concerning the matter with
respect to which the claim was asserted, the opportunity to correct and prevent
any statement or omission and any other equitable considerations appropriate
under the circumstances. Issuer and each Person selling securities agree with
each other that no seller of Registrable Securities shall be required to
contribute any amount in excess of the amount such seller would have been
required to pay to an indemnified party if the indemnity under Section 7.8 were
available. No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation. Issuer and
each such seller agree with each other, and the underwriters of the Registrable
Securities if requested by such underwriters, that it would not be equitable if
the amount of such contribution were determined by pro rata or per capita
allocation (even if the underwriters were treated as one entity for such
purpose) or for the underwriters' portion of such contribution to exceed the
percentage that the underwriting discount bears to the initial public offering
price of the Registrable Securities. For purposes of this Section 7.9, each
Person, if any, who controls an underwriter within the meaning of Section 15 of
the Securities Act shall have the same rights to contribution as such
underwriter, and each director and each officer of Issuer who signed the
registration statement, and each Person, if any, who controls Issuer or a seller
of Registrable Securities within the meaning of Section 15 of the Securities
Act, shall have the same rights to contribution as Issuer or a seller of
Registrable Securities, as the case may be.

     SECTION 7.10   Participation in Underwritten Registrations.  No Person may
                    -------------------------------------------
participate in any registration hereunder which is underwritten unless such
Person (a)  agrees to sell such Person's securities on the basis provided in any
underwriting arrangements approved by the Person or Persons entitled hereunder
to approve such arrangements and (b) completes and executes all questionnaires,
powers of attorney, indemnities, underwriting agreements and other documents
required under the terms of such underwriting arrangements.

     SECTION 7.11   Recapitalization of Nonvoting Stock.  At any time any holder
                    -----------------------------------
of non-voting Registrable Securities wishes to sell such shares pursuant to a
public offering of shares of voting common stock, Issuer shall cause such shares
to be recapitalized into or exchanged for shares of voting common stock, such
recapitalization or exchange to become effective at such time as the
registration statement pertaining to such shares has been filed with and
declared effective by the SEC.

     SECTION 7.12   Adjustments Affecting Registrable Securities.  Issuer will
                    --------------------------------------------
not take any action, or permit any change to occur, with respect to its
securities which would materially adversely affect the ability of the Offerors
to include their Registrable Securities in a registration undertaken pursuant to
this Agreement or which would materially adversely affect the marketability of
such

                                      17
<PAGE>

Registrable Securities in any such registration (including, without limitation,
effecting a stock split or a combination of shares), except as contemplated by
the Reorganization Agreement.

                    ---------------------------

representatives, full access at all times during reasonable business hours and
on reasonable notice, to all the offices, properties, contracts, books, records,

business or its assets, including, such access as may be requested to allow

contract or take (or omit to take) any action which would, or is reasonably
likely to, (i) result in any of Issuer's representations or warranties contained
in this Agreement not being true and correct as of the Subsequent Closing Date
or (ii prevent Issuer from performing, satisfying and complying with all of its
covenants and agreements contained in this Agreement.

     SECTION 8.3    Standstill.  From and after the date hereof through the
                    ----------
seventh (7th) Anniversary, Purchasers agree that they will not, without the
prior consent of Issuer, seek to acquire, offer to acquire or agree to acquire
any equity securities of Issuer that would result in Purchasers' aggregate
ownership of equity securities of Issuer exceeding fifteen (15%) of Issuer's
outstanding equity securities (except by way of stock dividends or other
distributions made on a pro rata basis to all holders of the equity securities
held by Purchasers) to the extent the acquisition of such equity securities
would result in Issuer violating the Communications Act as in effect on the date
of such acquisition.

              VoiceStream Wireless and Omnipoint Announce Merger

    Agreement to Merge at 0.825 VoiceStream Shares Plus $8 in Cash for Each
         Omnipoint Share Hutchison Telecommunications Limited Invests
                            Additional $957 Million

BELLEVUE, Wash./BETHESDA, Md--June 23, 1999--Voicestream Wireless Corporation
(Nasdaq:VSTR - news), and Omnipoint Corporation (Nasdaq:OMPT - news) announced
today that their respective Boards of Directors have unanimously approved a
definitive agreement to merge.

VoiceStream also announced today that Hutchison Telecommunications PCS (USA)
Limited (Hutchison USA), a subsidiary of Hutchison Telecommunications Limited
and a shareholder in VoiceStream, has committed to make an additional cash
investment of $957 million into the combined company. In addition, VoiceStream
announced today that Cook Inlet Region Inc. (CIRI) has agreed to make an
investment in a newly created joint venture owned 50.1% by CIRI and 49.9% by
VoiceStream, in order to acquire the designated entity licenses held by
Omnipoint Corporation.

The total value of these transactions is over $9 billion.

``The combination of VoiceStream Wireless and Omnipoint brings together two
major providers of GSM (Global System for Mobile Communications) in the United
States making the combined company one of the largest licensees in the world
employing GSM technology'' said John W. Stanton, chairman and chief executive
officer of VoiceStream Wireless.

``After the merger the combined company, together with CIRI, will have licenses
to provide service to over 175 million people with operating systems from New
York to Hawaii. With licenses in 17 of the top 25 markets, the combined company
together with CIRI will be one of the major providers of telecommunications
services in the country.''

``This merger brings together two great companies, Omnipoint and VoiceStream''
said Doug Smith, chairman and chief executive officer of Omnipoint. ``The
combined company provides service to over one million customers. As the second
largest PCS license holder and the fourth largest wireless company in the United
States in terms of people in licensed areas, the combined company will reap the
benefits of increased scale and scope. The combination of our two companies will
be beneficial for consumers and will create opportunities for both employees as
well as shareholders as the new business competes in the telecommunications
marketplace.''

``Hutchison owns interests in wireless systems in twelve countries in five
continents. We made our initial investment in VoiceStream in 1997'' a Hutchison
Whampoa spokesman said. ``Through our association with VoiceStream Wireless we
are excited about this unique opportunity to participate in the current rapid
growth in wireless telecommunications in the United States. The U.S. mobile
market is one of the largest and most exciting growth opportunities in the world
today for digital mobile communications. Following the merger, VoiceStream will
be the largest GSM operator in the country. As VoiceStream's largest shareholder
both before and after the merger, the investment represents a significant step
in expanding Hutchison's global presence in the mobile communications
business.''

``We are excited to participate in this transaction with VoiceStream and
Omnipoint,'' said Carl H. Marrs, president and chief executive officer of CIRI.
``With this transaction, and the recent PCS auction results, CIRI becomes one of
the nation's most significant Designated Entity providers of PCS service. This
helps fulfill the FCC's and Congress' goals for this important program.''

VoiceStream and Omnipoint Merger

VoiceStream Wireless and Omnipoint Corporation will enter into a merger in which
VoiceStream will exchange 0.825 shares of VoiceStream common stock plus $8.00 in
cash for every share of Omnipoint common stock. There will be a cash or share
election option available to shareholders of Omnipoint subject to proration.
VoiceStream said that it expects the stock portion of the offer will be tax-free
to Omnipoint shareholders. This merger is subject to shareholder approval as
well as federal, state, and other regulatory approvals including those of the
Federal Communications Commission, and the Department of Justice. Major
shareholders have agreed irrevocably to vote for the merger. VoiceStream also
has committed to invest $150 million in Omnipoint prior to the close of the
merger, including approximately $100 million to be provided immediately. The
merger is expected to close in the fourth quarter of 1999.

Hutchison USA Investment

Hutchison USA will be making an investment of $957 million into the combined
company for common and convertible preferred securities. The preferred provides
for a 2.5% cumulative dividend payable at maturity (40 years) and if converted
all accrued dividends will be canceled. A component of this investment will be
used as interim financing to purchase $150 million of convertible preferred
stock of Omnipoint on the same terms as VoiceStream, of which approximately $100
million will be provided immediately, which upon closing will be converted into
equity of VoiceStream. The remaining $807 million will be invested into the
combined company upon the closing of the merger. Hutchison USA is currently the
largest shareholder of VoiceStream stock, owning 24% of the company. Pro forma
for the merger and its additional investment, Hutchison USA will own
approximately 30% of the combined company on the exercise of certain conversion
rights.

CIRI Investment

CIRI and VoiceStream will form new joint ventures to acquire certain designated
entity communications licenses from Omnipoint upon closing of the merger. CIRI
will own 50.1% interest and VoiceStream will own the remaining 49.9% of the
ventures. CIRI and VoiceStream have two existing joint ventures and have been
successfully working together since 1995.

Management

John W. Stanton will remain the chairman and chief executive officer of
VoiceStream. Doug Smith, the current chairman of Omnipoint, will become a vice
chairman of VoiceStream, will continue as chairman of Omnipoint Technologies,
