                                    ARTICLE 3

               EFFECT OF THE MERGERS ON SECURITIES OF VOICESTREAM,
                      OMNIPOINT AND THE MERGER SUBSIDIARIES

        SECTION 3.1 Conversion of Merger Subsidiaries Stock. At the Effective
Time, by virtue of the VoiceStream Merger and without any action on the part of
any of the parties, each share of the common stock of Merger Sub A outstanding
immediately prior to the Effective Time shall be converted into and shall become

Merger. At the Effective Time, by virtue of the Omnipoint Merger and without any
action on the part of any of the parties, each share of the common stock of
Merger Sub B outstanding immediately prior to the Effective Time shall be
converted into and shall become one share of common stock of the surviving
corporation of the Omnipoint Merger.

        SECTION 3.2 Cancellation of Holding Company Capital Stock. At the
Effective Time, the one share of the capital stock of Holding Company issued to
VoiceStream and outstanding immediately prior to the Effective Time shall be

        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.



                                       15
<PAGE>   17

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");

                (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



                                       16
<PAGE>   18

        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 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



                                       17
<PAGE>   19

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 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



                                       18
<PAGE>   20

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).

                (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



                                       19
<PAGE>   21

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
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. (a) 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 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.



                                       21
<PAGE>   23

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.

                (a) 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.

                (b) 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 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



                                       22
<PAGE>   24

Options and New VoiceStream Options have been issued and complied with such rule
prior to the Transactions.

                (c) 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.

                (d) 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)



                                       23
<PAGE>   25

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

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 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



                                       24
<PAGE>   26

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

(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 holds, and is qualified and eligible to hold, all material licenses,
permits and other authorizations issued or to be issued by the FCC (including
"Winning Bids in Auction 22 Not yet Licenced by FCC," as referred to in the
Omnipoint Disclosure Schedule) to such entity for the operation of their
respective businesses, all of which are set forth in the Omnipoint Disclosure
Schedule (the "Omnipoint FCC Licenses").

                (b) The Omnipoint FCC Licenses are valid and in full force and
effect and none of Omnipoint, any of the Omnipoint Subsidiaries or any Omnipoint
Investment is or has been delinquent in payment on or in default under any

Omnipoint FCC Licenses.

                (c) All material reports and applications required by the
Communications Act or required to be filed with the FCC by any member of the
Omnipoint Group or any Omnipoint Investment have been filed and are accurate and
complete in all material respects.

Investment is, and has been, in compliance in all material respects with, and
the wireless communications systems operated pursuant to the Omnipoint FCC
Licenses have been operated in compliance in all material respects with, the
Communications Act.

                (e) There is not pending as of the date hereof any application,
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
violation or breach of any provision of the certificate of incorporation,
bylaws, stockholders agreement or other governing instrument of any member of
the Omnipoint Group or any Omnipoint Investment; (ii) assuming compliance with
the matters referred to in Section 4.3, contravene, conflict with or result in a
violation or breach of any provision of any applicable law, statute, ordinance,
rule, regulation, judgment, injunction, order, or decree; (iii) require any
consent or other action by any Person under, constitute a default (or an event
that, with or without notice or lapse of time or both, would constitute a
default) under, or cause or permit the termination, cancellation, acceleration,
triggering or other change of any right or obligation or the loss of any benefit
to which any member of the Omnipoint Group or any Omnipoint Investment is
entitled under (A) any provision of any agreement or other instrument binding
upon any member of the Omnipoint Group or any Omnipoint Investment or (B) any
license, franchise, permit, certificate, approval or other similar authorization
held by, or affecting, or relating in any way to, the assets or business of, any
member of the Omnipoint Group or any Omnipoint 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 Adverse Effect.

                (c) As of its filing date, each Omnipoint SEC Document complied
as to form in all material respects with the applicable requirements of the 1933
Act and the 1934 Act, as the case may be.

                (d) As of its filing date, each Omnipoint SEC Document filed
pursuant to the 1934 Act did not contain any untrue statement of a material fact
or omit to state any material fact necessary in order to make the statements
made therein, in the light of the circumstances under which they were made, not
misleading.

                (e) Each Omnipoint SEC Document that is a registration
statement, as amended or supplemented, if applicable, filed pursuant to the 1933
Act, as of the date such registration statement or amendment became effective,
did not contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary to make the statements
therein not misleading.

        SECTION 4.9 Financial Statements. The audited consolidated financial
statements and unaudited consolidated interim financial statements of Omnipoint
included in the Omnipoint SEC Documents fairly present, in all material
respects, in conformity with generally accepted accounting principles ("GAAP")
applied on a consistent basis (except as may be indicated in the notes thereto),
the consolidated financial position of Omnipoint and its consolidated
Subsidiaries as of the dates thereof and their consolidated results of
operations and cash flows for the periods then ended (subject to normal year-end
adjustments in the case of any unaudited interim financial statements).

        SECTION 4.10 Absence of Certain Changes. Since the Omnipoint Balance
Sheet Date, the business of each member of the Omnipoint Group and each
Omnipoint Investment has been conducted in the ordinary course consistent with
past practices and there has not been any event, occurrence or development
which, individually or in the aggregate, has had or would be reasonably expected
to have a Omnipoint Material Adverse Effect.

        SECTION 4.11 No Undisclosed Material Liabilities. There are no
liabilities or obligations of any member of the Omnipoint Group or any Omnipoint
Investment of any kind whatsoever, whether accrued, contingent, absolute,
determined, determinable or otherwise, and



                                       29
<PAGE>   31

there is no existing condition, situation or set of circumstances that would be
reasonably expected to result in such a liability or obligation, other than for
Taxes, if any, arising out of, or attributable to the Transactions (including
the CIRI Transaction and the transactions described in Recital A hereof):

                (a) liabilities or obligations disclosed and provided for in the
Omnipoint Balance Sheet or in the notes thereto or in Omnipoint SEC Documents
filed prior to the date hereof or in the Omnipoint 10-K; and

                (b) liabilities or obligations that, individually or in the
aggregate have not had and would not be reasonably expected to have a Omnipoint
Material Adverse Effect.

        SECTION 4.12 Compliance with Laws and Court Orders. Each member of the
Omnipoint Group and each Omnipoint Investment holds all licenses, franchises,
certificates, consents, permits, qualifications and authorizations from all
Governmental Bodies necessary for the lawful conduct of their business, except
where the failure to hold any of the foregoing, individually or in the
aggregate, has not had and would not be reasonably expected to have a Omnipoint
Material Adverse Effect. Each member of the Omnipoint Group and each Omnipoint
Investment is and has been in compliance with, and to the knowledge of
Omnipoint, is not under investigation with respect to and has not been
threatened to be charged with or given notice of any violation of, any such
license, franchise, certificate, consent, permit, qualification or
authorization, applicable law, statute, ordinance, rule, regulation, judgment,
injunction, order or decree, except for failures to comply or violations that,
individually or in the aggregate, have not had and would not be reasonably
expected to have a Omnipoint Material Adverse Effect.

        SECTION 4.13 Litigation. There is no action, suit, investigation or
proceeding (or any basis therefor) pending against, or, to the knowledge of
Omnipoint, threatened against or affecting, any member of the Omnipoint Group,
any Omnipoint Investment or any of their respective properties before any court
or arbitrator or before or by any other Governmental Body, that, individually or
in the aggregate, would be reasonably expected to have a Omnipoint Material
Adverse Effect.

        SECTION 4.14 Finders' Fees. Except for fees payable to Allen and Lehman
there is no investment banker, broker, finder or other intermediary that has
been retained by or is authorized to act on behalf of Omnipoint or any Omnipoint
Subsidiary who might be entitled to any fee or commission from VoiceStream, any
of the VoiceStream Subsidiaries, Omnipoint or any of the Omnipoint Subsidiaries
in connection with the Transactions. Copies of the engagement agreements with
Allen and Lehman have been provided to VoiceStream; except as set forth on such
engagement agreements, no other fees are payable to Allen and Lehman.

        SECTION 4.15 Opinion of Financial Advisor. Omnipoint has received an
opinion of Lehman, financial advisor to Omnipoint, to the effect that, as of
June 23, 1999, from a financial point of view, the Merger Consideration is fair
to the holders of Omnipoint Common Stock.

<PAGE>   32

        SECTION 4.16 Taxes. (a) Except as set forth in the Omnipoint Disclosure
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)
Omnipoint is not, and never has been the subject of a federal income tax
examination; and (vii) there are no Liens or encumbrances for Taxes on any of
the assets of Omnipoint or any Omnipoint Subsidiary except Liens for current
Taxes not yet due. For purposes of this Agreement, "Taxes" shall mean any and
all taxes, charges, fees, levies or other assessments, including, without
limitation, all net income, gross income, gross receipts, excise, stamp, real or
personal property, ad valorem, withholding, social security (or similar),
unemployment, occupation, use, service, service use, license, net worth,
payroll, franchise, severance, transfer, recording, employment, premium,
windfall profits, environmental (including taxes under Section 59A of the Code),
customs duties, capital stock, profits, disability, sales, registration, value
added, alternative or add-on minimum, estimated or other taxes, assessments or
charges imposed by any federal, state, local or foreign governmental body and
any interest, penalties, or additions to tax attributable thereto; provided,
however, that Taxes shall not include Taxes, if any, arising out of or
attributable to the Transactions (including the CIRI Transaction and the
transactions described in Recital A hereof). For purposes of this Agreement,
"Tax Returns" shall mean any return, report, form or similar statement required
to be filed with respect to any Tax (including any attached schedules),
including, without limitation, any information return, claim for refund, amended
return or declaration of estimated Tax.

                (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



                                       31
<PAGE>   33

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 Omnipoint that would, to Omnipoint's knowledge, prevent Piper Marbury from
delivering the opinion referred to in Section 9.3(b) as of the date hereof.

        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
thereto) and the most recent actuarial valuation report prepared in connection
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
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.



                                       32
<PAGE>   34

                (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.

        SECTION 4.19 Environmental Matters.

                (a) Except as have not had and would not be reasonably expected
to have, individually or in the aggregate, a Omnipoint Material Adverse Effect:

                (A) no notice, notification, demand, request for information,
        citation, summons or order has been received, no complaint has been
        filed, no penalty has been assessed, and no investigation, action,
        claim, suit, proceeding or review (or any basis therefor) is pending or,
        to the knowledge of Omnipoint, is threatened by any Governmental Body or
        other Person relating to or arising out of any Environmental Law;

                (B) each member of the Omnipoint Group and each Omnipoint
        Investment is and has been in compliance with all Environmental Laws and
        all Environmental Permits; and



                                       33
<PAGE>   35

                (C) there are no liabilities of or relating to any member of the
        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 Subsidiary shall include any entity that is, in whole or in part, a
predecessor of any member of the Omnipoint Group or any Omnipoint Investment.

        SECTION 4.20 Intellectual Property. With such exceptions as,
individually or in the aggregate, have not had and would not be reasonably
expected to have a Omnipoint Material Adverse Effect, each member of the
Omnipoint Group and each 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 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) any non-competition agreement or any other agreement or obligation which
materially limits or will materially limit any member of the Omnipoint Group or
any Investment Interest from engaging in the business of providing wireless
communications services or from developing wireless communications technology
anywhere in the world or (iii) any management agreement, technical services
agreement or other agreement whereby any member of the Omnipoint Group or any
Investment Interest is provided or is required to provide



                                       34
<PAGE>   36

management or technical services to any other Person . With such exceptions as,
individually or in the aggregate, have not had, and would not be reasonably
expected to have, a Omnipoint Material Adverse Effect, (x) each of the
contracts, agreements and 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 failed to perform any act which, with or without
notice, lapse of time, or both would constitute a default or other breach under
the provisions of, such contract, agreement or commitment, except for defaults
or breaches which, individually or in the aggregate, have not had, or would not
reasonably be expected to have, a Omnipoint Material Adverse Effect. Neither any
member of the Omnipoint Group nor any Omnipoint Investment is a party to, or
otherwise a guarantor of or liable with respect to, any interest rate, currency
or other swap or derivative transaction, other than any such transactions which
are not material to the business of the Omnipoint Group. Omnipoint has provided
or made available to VoiceStream a copy of each agreement described in item (i),
(ii) or (iii) above.

        SECTION 4.22 Significant Omnipoint Employees. The Omnipoint Disclosure
Schedule contains a list setting forth the name and current annual salary and
other compensation payable to each Significant Omnipoint Employee, and the
profit sharing, bonus or other form of additional compensation paid or payable
by Omnipoint to or for the benefit of each such person for the current fiscal
year. Except as set forth on the Omnipoint Disclosure Schedule or under the
employment, consulting or other agreements listed thereon, there are no oral or
written contracts, agreements or arrangements obligating Omnipoint to increase
the compensation or benefits presently being paid or hereafter payable to any
Significant Omnipoint Employees. The Omnipoint Disclosure Schedule annexed
hereto sets forth summaries of all oral employment or consulting or similar
arrangements regarding any Significant Omnipoint Employee which are not
terminable without liability on thirty (30) days' or less prior notice and lists
all written employment and consulting agreements with respect to any Significant
Omnipoint Employee, true and complete copies of which have been provided to
VoiceStream. Except for severance obligations to Significant Omnipoint Employees
set forth on the Omnipoint Disclosure Schedule, there is not due or owing and
there will not be due and owing at the Effective Time to any Significant
Omnipoint Employees, any sick pay, severance pay (whether arising out of the
termination of an Significant Omnipoint Employee prior to, on, or subsequent to
the Effective Time), compensable time or pay, including salary, commission and
bonuses, personal time or pay or vacation time or vacation pay attributable to
service rendered on or prior to the Effective Time. Except as disclosed in the
Omnipoint Disclosure Schedule and other than claims made in the ordinary course
of business consistent with past practice in an aggregate amount not to exceed
$100,000, neither Omnipoint nor the Omnipoint Subsidiaries have, any liability
arising out of claims made or suits brought (including workers' compensation
claims and claims or suits for contribution to, or indemnification of, third
parties, occupational health and safety, environmental, consumer protection or
equal employment matters) for injury, sickness, disease,



                                       35
<PAGE>   37

discrimination, death or termination of employment of any Significant Omnipoint
Employee, or other employment matter to the extent attributable to an event
occurring or a state of facts existing on or prior to the Effective Time.

        SECTION 4.23 Employment Matters. Omnipoint and each Omnipoint Subsidiary
(A) is in compliance with all applicable Federal and state laws, rules and
regulations respecting employment, employment practices, terms and conditions of
employment and wages and hours, in each case, with respect to Omnipoint
Employees, except where the failure to be in compliance would not, singly or in
the aggregate, have a material adverse effect on Omnipoint, any Omnipoint
Subsidiary or their financial condition or business; (B) has withheld all
amounts required by law or by agreement to be withheld from the wages, salaries
and other payments to Omnipoint Employees; (C) is not liable for any arrears of
wages or any taxes or any penalty for failure to comply with any of the
foregoing, except as would reasonably be expected to not have a Omnipoint
Material Adverse Effect; and (D) (other than routine payments to be made in the
normal course of business and consistent with past practice) is not liable for
any payment to any trust or other fund or to any governmental or administrative
authority, with respect to unemployment compensation benefits, Social Security
or other benefits for Omnipoint Employees.

        SECTION 4.24 Labor. No work stoppage or labor strike with respect to
Omnipoint Employees is pending or, to the best knowledge of Omnipoint, is
threatened. Except as set forth on the Omnipoint Disclosure Schedules, there is
no involvement nor, to the best knowledge of Omnipoint, is there threatened, any
labor dispute, grievance or litigation relating to labor, safety or
discrimination matters involving any Omnipoint Employee including charges of
unfair labor practices or discrimination complaints, which, if adversely
determined, would reasonably be expected to have, individually or in the
aggregate, a material adverse effect on its financial condition or business.
There has been no engagement in any unfair labor practices within the meaning of
the National Labor Relations Act which would reasonably be expected to have,
individually or in the aggregate, a Omnipoint Material Adverse Effect.

        SECTION 4.25 Vote Required. The only vote of the holders of any class or
series of capital stock of Omnipoint necessary to approve this Agreement and the
Transactions is the affirmative vote of the holders of a majority of the
outstanding shares of Omnipoint Common Stock (the "Omnipoint Stockholders'
Approval").

        SECTION 4.26 Antitakeover Statutes and Charter Provisions. Omnipoint has
taken all action necessary to exempt the Omnipoint Merger and this Agreement and
the Transactions from the restrictions of Section 203 of Delaware Law, and,
accordingly, neither such Section nor any other antitakeover or similar statute
or regulation applies or purports to apply to any such transactions. No other
"control share acquisition," "fair price," "moratorium" or other antitakeover
laws or regulations enacted under U.S. state or federal laws apply to this
Agreement or any of the Transactions.



                                       36
<PAGE>   38

        SECTION 4.27 Insurance. The Omnipoint Disclosure Schedules set forth a
list and brief description of all policies of fire, liability and other forms of
insurance and material fidelity bonds held by the Omnipoint Group. The Omnipoint
Group's assets, business, equipment, property and operations are adequately
insured against loss or damage and all other hazards or risks of the character
usually insured against by companies in the same or similar business and such
insurance shall be continued in full force and effect through 11:59 p.m. on the
Effective Time. Each such policy and fidelity bond is in full force and effect,
all premiums due and payable under such policies and fidelity bonds have been
and on the Effective Time will be paid in full, and there are no disputed claims
arising under such policies or fidelity bonds.

        SECTION 4.28 Bank Accounts. The Disclosure Schedule sets forth a
complete list of all bank accounts, savings deposits, money-market accounts,
certificates of deposit, safety deposit boxes, and similar investment accounts
with banks or other financial institutions maintained by or on behalf of the
Omnipoint or any Omnipoint Subsidiary showing the depository bank or institution
address, appropriate bank contact personnel, account number and names of
signatories.

        SECTION 4.29 Transactions with Affiliates. No Affiliate of the Omnipoint
Group or Omnipoint Investment nor any stockholder, officer, director, partner,
member, consultant or employee of any thereof, is at the date hereof a party to
any transaction with any member of the Omnipoint Group or Omnipoint Investment,
including any contract or arrangement providing for the furnishing of services
to or by, providing for rental of real or personal property (including
intellectual property) to or from, or otherwise requiring payments to or from
any member of the Omnipoint Group or any Omnipoint Investment, or any Affiliate
thereof.

                                       37

executed and delivered by VoiceStream and Holding Company and, assuming the due

incorporation and by applicable Delaware Law and Washington Law.

        SECTION 5.3 Governmental Authorization.

                (a) The execution, delivery and performance by VoiceStream of

filing, the absence of which would not in the aggregate prevent or delay
consummation of the Transactions in any material respect, or otherwise prevent
VoiceStream from performing its obligations under this Agreement in any material
respect or would not in the aggregate have a VoiceStream Material Adverse
Effect.

                (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

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 VoiceStream Group or any
VoiceStream Investment which questions the validity of or contests any
VoiceStream FCC License or which presents a substantial risk that, if accepted
or granted, or concluded adversely, could result in the revocation,
cancellation, suspension or any materially adverse modification of any
VoiceStream FCC License or imposition of any substantial fine or forfeiture
against any member of the VoiceStream Group or any VoiceStream Investment except
as set forth in the VoiceStream Disclosure Statement.

                (f) No facts are known to any Member of the VoiceStream Group

                (b) Except as set forth in Section 5.6(a) or on the VoiceStream
Disclosure Schedules, there are no outstanding subscriptions, options, warrants,

                                       40
<PAGE>   42

stock based or stock related plan or award. There are no preemptive rights,
rights of first refusal, rights of first offer or any similar rights granted
with respect to the securities or any assets of any member of the VoiceStream
Group.

        SECTION 5.7 Subsidiaries; Investments.

                (a) Each VoiceStream Subsidiary and each VoiceStream Investment
is a corporation or other legal entity duly organized, validly existing and in
good standing under the laws of its jurisdiction of organization and has all
corporate, partnership or other similar powers required to carry on its business
as now conducted, other than such exceptions as, individually or in the
aggregate, have not had and would not be reasonably expected to have a
VoiceStream Material Adverse Effect. Each VoiceStream Subsidiary and each
VoiceStream Investment is duly qualified to do business as a foreign corporation
or other foreign legal entity and is in good standing in each jurisdiction where
such qualification is necessary, with such exceptions, individually or in the
aggregate, as have not had and would not be reasonably expected to have a
VoiceStream Material Adverse Effect. The VoiceStream Disclosure Schedule sets
forth a list of all VoiceStream Subsidiaries and all VoiceStream Investments and
their respective jurisdictions of organization and identifies VoiceStream's
(direct or indirect) percentage ownership interest therein.

                (b) All of the outstanding capital stock of, or other voting
securities or ownership interests in, each VoiceStream Subsidiary and each
VoiceStream Investment, is owned by VoiceStream or a VoiceStream Subsidiary,
directly or indirectly, free and clear of any Lien and free of any other
limitation or restriction (including any restriction on the right to vote, sell
or otherwise dispose of such capital stock or other voting securities or
ownership interests).

                (c) There are no outstanding subscriptions, options, warrants,
rights or convertible or exchangeable securities issued by any member of the
VoiceStream Group or a VoiceStream Investment or other agreements or commitments
of any character relating to the issued or unissued capital stock or other
securities or partnership interests or membership interests of any VoiceStream
Subsidiary or any VoiceStream Investment, including any agreement or commitment
obligating any member of the



                                       41
<PAGE>   43

VoiceStream Group or any VoiceStream Investment to issue, deliver or sell, or
cause to be issued, delivered or sold, shares of capital stock, other
securities, partnership interests or membership interests of any VoiceStream
Subsidiary or any VoiceStream Investment or obligating any member of the
VoiceStream Group or any VoiceStream Investment to grant, extend or enter into
any subscription, option, warrant, right or convertible or exchangeable security
or other similar agreement or commitment with respect to any VoiceStream
Subsidiary or any VoiceStream Investment, or obligating any member of the
VoiceStream Group or any VoiceStream Investment to make any payments pursuant to
any stock based or stock related plan or award. No member of the VoiceStream
Group is subject to any obligation or requirement to provide funds for or to
make any investment (in the form of a loan, capital contribution or otherwise)
to or in any Person, (other than obligations to individuals who are employees,
which obligations (i) are set forth in Section 5.22 of the VoiceStream
Disclosure Schedule or (ii) are for de minimis amounts and are made in the
ordinary course of business consistent with past practices), including, without
limitation, any VoiceStream Investment.

                (d) VoiceStream has previously delivered or made available to
Omnipoint true and complete copies of the organizational documents or comparable
governing instruments (including all amendments to each of the foregoing), of
each VoiceStream Subsidiary and each VoiceStream Investment as in effect on the
date hereof.

        SECTION 5.8 SEC Filings.

                (a) VoiceStream has filed all required reports, schedules,
forms, statements and other documents required to be filed by it with the SEC
since January 1, 1997.

                (b) VoiceStream has delivered or made available to Omnipoint:
(i) the VoiceStream 10-K; (ii) its proxy or information statements relating to
meetings of, or actions taken without a meeting by, the stockholders of
VoiceStream held since December 31, 1998; and (iii) all of its other reports,
statements, schedules, forms, exhibits and registration statements and all other
documents required to be filed with the SEC since December 31, 1998 (the "1999
VoiceStream SEC Documents") (the documents referred to in Sections 5.8(a) and
(b), collectively, the "VoiceStream SEC Documents"). The VoiceStream Disclosure
Schedule sets forth a list of all the 1999 VoiceStream SEC Documents.

                (c) As of its filing date, each VoiceStream SEC Document
complied as to form in all material respects with the applicable requirements of
the 1933 Act and the 1934 Act, as the case may be.

                (d) As of its filing date, each VoiceStream SEC Document filed
pursuant to the 1934 Act did not contain any untrue statement of a material fact
or omit to state any material fact necessary in order to make the statements
made therein, in the light of the circumstances under which they were made, not
misleading.

                (e) Each VoiceStream SEC Document that is a registration
statement, as amended or supplemented, if applicable, filed pursuant to the 1933
Act, as of the date such registration statement or amendment became effective,
did not contain any untrue statement of a



                                       42
<PAGE>   44

material fact or omit to state any material fact required to be stated therein
or necessary to make the statements therein not misleading.

        SECTION 5.9 Financial Statements. The audited consolidated financial
statements and unaudited consolidated interim financial statements of
VoiceStream included in the VoiceStream SEC Documents fairly present, in all
material respects, in conformity with GAAP applied on a consistent basis (except
as may be indicated in the notes thereto), the consolidated financial position
of VoiceStream and its consolidated Subsidiaries as of the dates thereof and
their consolidated results of operations and cash flows for the periods then
ended (subject to normal year-end adjustments in the case of any unaudited
interim financial statements).

        SECTION 5.10 Absence of Certain Changes. Since the VoiceStream Balance
Sheet Date, the business of each member of the VoiceStream Group and each
VoiceStream Investment has been conducted in the ordinary course consistent with
past practices and there has not been any event, occurrence or development
which, individually or in the aggregate, has had or would be reasonably expected
to have a VoiceStream Material Adverse Effect.

        SECTION 5.11 No Undisclosed Material Liabilities. There are no
liabilities or obligations of any member of the VoiceStream Group or any
VoiceStream Investment of any kind whatsoever, whether accrued, contingent,
absolute, determined, determinable or otherwise, and there is no existing
condition, situation or set of circumstances that would be reasonably expected
to result in such a liability or obligation, other than for taxes, if any,
arising out of, or attributable to the Transactions (including the CIRI
Transaction and the transactions described in Recital A hereof), or:

                (a) liabilities or obligations disclosed and provided for in the
VoiceStream Balance Sheet or in the notes thereto or in VoiceStream SEC
Documents filed prior to the date hereof or in the VoiceStream 10-K; and

                (b) liabilities or obligations that, individually or in the
aggregate have not had and would not be reasonably expected to have a
VoiceStream Material Adverse Effect.

        SECTION 5.12 Compliance with Laws and Court Orders. Each member of the
VoiceStream Group and each VoiceStream Investment holds all licenses,
franchises, certificates, consents, permits, qualifications and authorizations
from all Governmental Bodies necessary for the lawful conduct of their business,
except where the failure to hold any of the foregoing, individually or in the
aggregate, has not had and would not be reasonably expected to have a
VoiceStream Material Adverse Effect. Each member of the VoiceStream Group and
each VoiceStream Investment is and has been in compliance with, and to the
knowledge of VoiceStream, is not under investigation with respect to and has not
been threatened to be charged with or given notice of any violation of, any such
license, franchise, certificate, consent, permit, qualification or
authorization, applicable law, statute, ordinance, rule, regulation, judgment,
injunction, order or decree, except for failures to comply or violations that,
individually or in the



                                       43
<PAGE>   45
aggregate, have not had and would not be reasonably expected to have a
VoiceStream Material Adverse Effect.

        SECTION 5.13 Litigation. There is no action, suit, investigation or
proceeding (or any basis therefor) pending against, or, to the knowledge of
VoiceStream, threatened against or affecting, any member of the VoiceStream
Group or any VoiceStream Investment or any of their respective properties before
any court or arbitrator or before or by any other Governmental Body, that,
individually or in the aggregate, would be reasonably expected to have a
VoiceStream Material Adverse Effect.

        SECTION 5.14 Finders' Fees. Except for fees payable to Goldman, there is
no investment banker, broker, finder or other intermediary that has been
retained by or is authorized to act on behalf of VoiceStream or any VoiceStream
Subsidiary who might be entitled to any fee or commission from Omnipoint, any of
the Omnipoint Subsidiaries, VoiceStream or any of the VoiceStream Subsidiaries
in connection with the Transactions. A copy of the engagement agreement with
Goldman has been provided to Omnipoint; except as set forth on such engagement
agreement, no other fees are payable to Goldman.

        SECTION 5.15 Opinion of Financial Advisor. VoiceStream has received an
opinion of Goldman, financial advisor to VoiceStream, to the effect that, as of
June 23, 1999, from a financial point of view, the Merger Consideration is fair
to the holders of VoiceStream Common Stock.

        SECTION 5.16 Taxes. (a) Except as set forth in the VoiceStream
Disclosure Schedules and except as would not have a VoiceStream Material Adverse
Effect, (i) all VoiceStream Tax Returns required to be filed with any taxing
authority by, or with respect to, VoiceStream and the VoiceStream Subsidiaries
have been filed in accordance with all applicable laws or an appropriate
extension of time to file such VoiceStream Tax Return has been obtained; (ii)
VoiceStream and the VoiceStream Subsidiaries have timely paid all Taxes shown as
due and payable on the VoiceStream Tax Returns that have been so filed, and, as
of the time of filing, the VoiceStream Tax Returns correctly reflected the facts
regarding the income, business, assets, operations, activities and the status of
VoiceStream and the VoiceStream Subsidiaries (other than Taxes which are being
contested in good faith by appropriate proceeding and for which adequate
reserves are reflected on the VoiceStream Balance Sheet); (iii) VoiceStream and
the VoiceStream Subsidiaries have made provision for all Taxes payable by
VoiceStream and the VoiceStream Subsidiaries for which no VoiceStream Tax Return
has yet been filed; (iv) the charges, accruals and reserves for Taxes with
respect to VoiceStream and the VoiceStream Subsidiaries reflected on the
VoiceStream 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 VoiceStream, threatened
against or with respect to VoiceStream or any VoiceStream Subsidiary in respect
of any Tax where an adverse determination is reasonably likely; (vi) the federal
income Tax Returns of VoiceStream and the VoiceStream Subsidiaries have been
examined and settled with the IRS (or the applicable statutes of limitation for
the assessment of federal income Taxes for such periods have expired)


                                       44


<PAGE>   46
for all years through 1997; and (vii) there are no Liens or encumbrances for
Taxes on any of the assets of VoiceStream or any VoiceStream Subsidiary except
liens for current Taxes not yet due.

               (b) To the knowledge of VoiceStream, there is no plan or
intention on the part of any VoiceStream shareholder to sell, exchange, transfer
or otherwise dispose of any stock of Holding Company received in the
Transactions, except that VoiceStream shareholders that 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).

               (c) The maximum number of shares of Holding Company Common Stock
which may be issued pursuant to conversion rights held by the Cook Entities
(after consummation of the Transactions), including conversion rights under the
CIRI Agreements, is 9,000,000.

        SECTION 5.17 Tax Opinions. There are no facts or circumstances relating
to VoiceStream that would, to VoiceStream's knowledge, prevent Jones Day from
delivering the opinions referred to in Sections 9.2(b) and 9.2(c) as of the date
hereof.

        SECTION 5.18 Employee Benefit Plans and Labor Matters.

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

               (b) No "accumulated funding deficiency," as defined in Section
412 of the Code, has been incurred with respect to any VoiceStream 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 VoiceStream Employee Plan. Neither VoiceStream
nor to VoiceStream's knowledge any ERISA Affiliate of VoiceStream 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


                                       45


<PAGE>   47
the Code 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 to occur as of the Effective Time with respect to all
Multiemployer Plans, neither of VoiceStream, nor any VoiceStream 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 VoiceStream Pension Plan (excluding for these purposes any accrued but
unpaid contributions) exceeded the present value of all benefits accrued under
such VoiceStream Pension Plan calculated pursuant to FAS No. 87, "Employers'
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.

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

               (g) Each VoiceStream Employee Plan and each VoiceStream 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 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


                                       46


<PAGE>   48
organizing effort or representation question at issue with respect to any
employee of VoiceStream or any of the VoiceStream Subsidiaries.

        SECTION 5.19 Environmental Matters.

               (a) Except as have not had and would not be reasonably expected
to have, individually or in the aggregate, a VoiceStream Material Adverse
Effect:

                (A) no notice, notification, demand, request for information,
        citation, summons or order has been received, no complaint has been
        filed, no penalty has been assessed, and no investigation, action,
        claim, suit, proceeding or review (or any basis therefor) is pending or,
        to the knowledge of VoiceStream, is threatened by any Governmental Body
        or other Person relating to or arising out of any Environmental Law;

                (B) each member of the VoiceStream Group and each VoiceStream
        Investment is and has been in compliance with all Environmental Laws and
        all Environmental Permits; and

                (C) there are no liabilities of or relating to any member of the
        VoiceStream Group or any VoiceStream 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 Reports of which VoiceStream
has knowledge in relation to the current or prior business of any member of the
VoiceStream Group or any VoiceStream Investment or any property or facility now
or previously owned or leased by any member of the VoiceStream Group or any
VoiceStream Investment that reveal matters that, individually or in the
aggregate, have had or would reasonably be expected to have a VoiceStream
Material Adverse Effect; and

               (c) For purposes of this Section 5.19, the terms VoiceStream and
VoiceStream Subsidiary shall include any entity that is, in whole or in part, a
predecessor of any member of the VoiceStream Group or any VoiceStream
Investment.

        SECTION 5.20 Intellectual Property. With such exceptions as,
individually or in the aggregate, have not had and would not be reasonably
expected to have a VoiceStream Material Adverse Effect, each member of the
VoiceStream Group and each VoiceStream Investment owns or has 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 "VoiceStream Intellectual
Property") necessary to carry on its business substantially as currently


                                       47


<PAGE>   49
conducted. No member of the VoiceStream Group or any VoiceStream Investment has
received any notice of infringement of or conflict with, and to VoiceStream's
knowledge, there are no infringements of or conflicts with, the rights of any
Person with respect to the use of any VoiceStream Intellectual Property that, in
either such case, individually or in the aggregate, have had or would be
reasonably expected to have, a VoiceStream Material Adverse Effect.

        SECTION 5.21 Contracts. No member of the VoiceStream Group nor any
VoiceStream 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) any non-competition agreement or any other agreement or obligation which
materially limits or will materially limit any member of the VoiceStream Group
or any VoiceStream Investment Interest from engaging in the business of
providing wireless communications services or from developing wireless
communications technology anywhere in the world or (iii) any management
agreement, technical services agreement or other agreement whereby any member of
the VoiceStream Group or any of its Investment Interest is provided or is
required to provide management or technical services to any other Person. With
such exceptions as, individually or in the aggregate, have not had, and would
not be reasonably expected to have, a VoiceStream Material Adverse Effect, (x)
each of the contracts, agreements and commitments of the VoiceStream Group and
the VoiceStream Investments is valid and in full force and effect and (y)
neither any member of the VoiceStream Group nor any VoiceStream Investments 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

VoiceStream's officers' and directors' liability insurance policy (with respect
to officers and directors of the VoiceStream Group) on terms with respect to
coverage and amount (including with respect to the payment of attorney's fees)
no less favorable than those of such policy in effect on the date hereof (which
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.

               (c) The rights of each Indemnified Person and its heirs and legal
representatives under this Section 7.2 shall be in addition to any rights such
Person may have under the certificate of incorporation or bylaws of any member

best efforts to cause (i) the shares of Holding Company Common Stock to be
issued in connection with the Transactions (and the shares of Holding Company
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
Transactions.

        SECTION 7.4 Holding Company Board of Directors. Immediately prior to the
Effective Time, the Board of Directors of Holding Company will take all
necessary action to expand the size of its Board of Directors of Holding Company
to 14 members and to appoint to the Holding Company Board, as of the Effective
Time, 4 current members of the Omnipoint Board selected by Omnipoint who agrees

nominate the New Directors for reelection to the Holding Company Board of
Directors at each subsequent annual or special meeting of the stockholders of
Holding Company at which the New Directors' term expires. The provisions of this
Section 7.4 shall survive the consummation of the Transactions and are intended
to benefit, and shall be enforceable by, the New Directors.

        SECTION 7.5 Employee Matters.

               (a) Holding Company shall, or shall cause its Subsidiaries 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 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.

and the earlier of the effective time of the termination of this Agreement,
between the date hereof and the earlier of the Effective Time or the Termination
of this Agreement, shall (i) give to Omnipoint and Omnipoint's counsel,

interfere unreasonably with the conduct of the business of VoiceStream.

        SECTION 7.7 Covenants with Respect to Holding Company.

               (a) Holding Company will not issue any stock as compensation for
services in connection with the Transactions or take any other action which may
cause such Transactions not to qualify as an exchange under Section 351 of the
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.

               (c) Holding Company will not take any action, or cause
VoiceStream or Omnipoint to take any action, which may cause the Transactions
not to qualify as an exchange under Section 351 of the Code.

        SECTION 7.8 Registration Rights. Not later than 15 days after the
Closing Date, Holding Company shall prepare and file with the SEC a registration
statement (the "Affiliate Registration Statement") on Form S-1, S-3, if the
Holding Company is eligible to use such form, or any other filing form which
Holding Company shall deem appropriate, with respect to the sale of the shares
of Holding Company Common Stock to be held by any "affiliate" (as such term is
defined under Rule 145 of the 1933 Act) (and their limited partners) of either
Omnipoint or VoiceStream immediately following the Effective Time (the
"Affiliate Shares"). Holding Company shall take all reasonable steps necessary
to ensure that the Affiliate Registration Statement does not, as of its
effective date, contain any untrue statement of a material fact or omit to state
a material fact required to be stated therein or necessary to make the
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
determines in good faith to be customary and appropriate until the earlier of
(i) one year after its effective date,

Shares may be sold without registration under the 1933 Act.

                     COVENANTS OF VOICESTREAM AND OMNIPOINT

                     Each of the parties hereto agree that:

        SECTION 8.1 Best Efforts.

               (a) Subject to the terms and conditions of this Agreement, each
of the 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 Transactions as soon as practicable, including 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, and (ii) obtain and maintain all
approvals, consents, registrations, permits, authorizations and other
confirmations required to be obtained from any third party (including consents
of the FAA and other 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 done, all things necessary, proper or advisable under applicable laws and
regulations to consummate the Transactions as soon as practicable, including
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
retain) any member of the Omnipoint Group or any Omnipoint Investment or any
material portion of the assets of the VoiceStream Group or any of the
VoiceStream Group's business, product lines, or assets of the Omnipoint Group,
(iii) consummate the CIRI Transactions, and (iv) consummate the Hutchison
Transaction. At VoiceStream's request, Omnipoint will commit to and implement
any divestiture, hold separate or similar transaction or action with respect to
any asset or business of the Omnipoint Group or any Omnipoint Investment, which
commitment and implementation may, at Omnipoint's option, be conditioned upon
and effective as of the Effective Time. Subject to applicable laws relating to
the exchange of information, VoiceStream and Omnipoint shall have the right to
review in advance, and to the extent practicable to consult with each other on,
all the information relating to any member of the Omnipoint Group or any
Omnipoint Investment or any member of the VoiceStream Group or VoiceStream
Investment, as


                                       61


<PAGE>   63
applicable, that appears in any filing made with, or written materials submitted
to, any third party and/or any Governmental Bodies in connection with the
Transactions.

               (b) As promptly as practicable after the execution and delivery
of this Agreement, VoiceStream and Omnipoint shall prepare all appropriate
applications for FCC approval, and such other documents as may be required, with
respect to the transfer of control of Omnipoint and VoiceStream to Holding
Company (collectively, the "FCC Applications"). Not later than the tenth
business day following execution and delivery of this Agreement, Omnipoint and
VoiceStream will exchange with each other their respective completed portions of
the FCC Applications. Not later than the fifteenth Business Day following the
execution and delivery of this Agreement, Omnipoint and VoiceStream shall file,
or cause to be filed, the FCC Applications. If the Effective Time shall not have
occurred for any reason within any applicable initial consummation period, and
neither Omnipoint nor VoiceStream shall have terminated this Agreement 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
knowingly take, or fail to take, any action if the intent or reasonably
anticipated consequence of such action or failure to act is, or would be, to
cause the FCC not to grant approval of the FCC Applications or delay either such
approval or the consummation of the transfer of control of Omnipoint.
VoiceStream and Omnipoint shall each pay one-half (1/2) of any FCC fees, if
applicable, in connection with the filing or granting of approval of the FCC
Applications. Each of VoiceStream and Omnipoint shall bear its own expenses in
connection with the preparation and prosecution of the FCC Applications.
VoiceStream and Omnipoint shall each use all reasonable efforts to prosecute the
FCC Applications in good faith and with due diligence before the FCC and in
connection therewith shall take such action or actions as may be necessary or
reasonably required in connection with the FCC Applications, including
furnishing to the FCC any documents, materials or other information requested by
the FCC in order to obtain such FCC approval as expeditiously as practicable.

               (c) Promptly after the date hereof, VoiceStream and Omnipoint (as
may be required pursuant to the HSR Act) will complete all documents required to
be filed with the Federal Trade Commission and the Department of Justice in
order to comply with the HSR Act and, not later than 10 Business Days after the
date hereof, together with the Persons who are required to join in such filings,
shall file the same with the appropriate Governmental Bodies. VoiceStream and
Omnipoint shall each pay one-half (1/2) of any fees that may be payable in
connection with the filing pursuant to the HSR Act. VoiceStream, and Omnipoint
shall promptly furnish all materials thereafter required by any of the
Governmental Bodies having jurisdiction over such filings, and shall take all
reasonable actions and shall file and use all reasonable efforts to have
declared effective or approved all documents and notifications with any such
Governmental Bodies, as may be required under the HSR Act or other federal
antitrust laws for the consummation of the Transactions and any other
transactions contemplated hereby.

               (d) In addition to the filings required by the HSR Act and the
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
Governmental Bodies (including, but


                                       62


<PAGE>   64
not limited to the FAA) the applications and related documents required to be
filed by such Governmental Bodies (and prosecute diligently any such
applications, including providing such information as such Governmental Bodies
may reasonably request) in order to consummate the Transactions, (ii) cooperate
with each other as may reasonably be requested in connection with the foregoing,
and (iii) otherwise use their best efforts to obtain promptly the requested
consent and approval of the applications by any applicable Governmental Bodies.
VoiceStream and Omnipoint shall each pay one half (1/2) of all filing or other
Governmental Body filing or grant fees in connection with the applications
requesting its consent to the consummation of the Transactions.

        SECTION 8.2 Registration Statement and Proxy Statement. VoiceStream and
Omnipoint shall cooperate and promptly prepare and file with the SEC as soon as
practicable a Registration Statement on Form S-4 (the "Form S-4") under the 1933
Act, with respect to the Holding Company Common Stock issuable in the Mergers, a
portion of which Registration Statement shall also serve as the joint proxy
statement with respect to the meetings of stockholders of Omnipoint and of
VoiceStream in connection with the Transactions (the "Proxy
Statement/Prospectus"). The respective parties shall cause the Proxy
Statement/Prospectus and the Form S-4 to comply as to form in all material
respects with the applicable provisions of the 1933 Act, the 1934 Act and the
rules and regulations thereunder. VoiceStream shall use all reasonable efforts,
and Omnipoint shall cooperate with VoiceStream, to have the Form S-4 declared
effective by the SEC as promptly as practicable and to keep the Form S-4
effective as long as is necessary to consummate the Transactions. VoiceStream
shall, as promptly as practicable, provide copies of any written comments
received from the SEC with respect to the Form S-4 to Omnipoint and advise
Omnipoint of any verbal comments with respect to the Form S-4 received from the
SEC. VoiceStream shall use its best efforts to obtain, prior to the effective
date of the Form S-4, all necessary state securities laws or "Blue Sky" permits
or approvals required to carry out the Transactions and shall pay all expenses
incident thereto. VoiceStream agrees that the Proxy Statement/Prospectus and
each amendment or supplement thereto at the time of mailing thereof and at the
time of the respective meetings of stockholders of Omnipoint and VoiceStream,
or, in the case of the Form S-4 and each amendment or supplement thereto, at the
time it is filed or becomes effective, shall not include an untrue statement of
a material fact or omit to state a material fact required to be stated therein
or necessary to make the statements therein, in light of the


                                       63


<PAGE>   65
circumstances under which they were made, not misleading; provided, however,
that the foregoing shall not apply 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 meetings of stockholders of Omnipoint and VoiceStream,
or, in the case of 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 becomes effective, shall not include an untrue
statement of a material fact or omit 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. No amendment or
supplement to the Proxy Statement/Prospectus shall be made by VoiceStream or
Omnipoint without the approval of the other party. VoiceStream shall advise
Omnipoint, promptly after it receives notice thereof, of the time when the Form
S-4 has become effective or any supplement or amendment has been filed, the
issuance of any stop order, the suspension of the qualification of VoiceStream
Common Stock issuable in connection with the Transactions for offering or sale
in any jurisdiction, or any request by the SEC for amendment of the Proxy
Statement/Prospectus or the Form S-4 or comments thereon and responses thereto
or requests by the SEC for additional information.

        SECTION 8.3 Public Announcements. So long as this Agreement is in
effect, Omnipoint and VoiceStream will consult with each other before issuing
any press release or making any public statement with respect to the
Transactions and except as may be required by applicable law or any listing
agreement with any national securities exchange, will not issue any such press
release or make any such public statement without the prior consent of the other
party, which consent shall not be unreasonably withheld or delayed.
Notwithstanding the foregoing, any such press release or public statement as may
be required by applicable law or any listing agreement with any national
securities exchange or NASDAQ may be issued without such consent, if the party
making such release or statement has used its reasonable efforts to consult with
the other party.

        SECTION 8.4 Further Assurances. At and after the Effective Time, the
officers and directors of Holding Company will be authorized to execute and
deliver, in the name and on behalf of Omnipoint or VoiceStream, any deeds, bills
of sale, assignments or assurances and to take and do, in the name and on behalf
of Omnipoint or VoiceStream, any other actions and things to vest, perfect or
confirm of record in Holding Company any and all right, title and interest in,
to and under any of the rights, properties or assets of Omnipoint or VoiceStream
acquired or to be acquired by Holding Company as a result of, or in connection
with, the Transactions.

        SECTION 8.5 Notices of Certain Events. Each of Omnipoint and VoiceStream
shall promptly notify the other of:

               (a) any notice or other communication from any Person alleging
that the consent of such Person is or may be required in connection with the
Transactions;

               (b) any notice or other communication from any Governmental Body
in connection with the Transactions;

               (c) the occurrence, or non-occurrence, of any event the

inaccurate in any material respect at any time during the period commencing on
the date hereof and ending at the Effective Time; provided,


                                       64


<PAGE>   66
however, that the delivery of any notice pursuant to this Section 8.5 shall not
limit or otherwise affect the remedies available hereunder to the party
receiving such notice;

               (d) any failure of such party to comply with or satisfy any
covenant, condition or agreement to be complied with or satisfied by it
hereunder; provided, however, that the delivery of any notice pursuant to this

to the party receiving such notice;

               (e) any actions, suits, claims, investigations or proceedings
commenced or, to its knowledge threatened against such party which, if pending
on the date of this Agreement, would have been required to have been disclosed
pursuant to Section 4.13, in the case of Omnipoint, or Section 5.13, in the case
of VoiceStream, or which relate to the consummation of the Transactions; and

               (f) any event, condition or state of facts which could have a
Material Adverse Effect on such party.

        SECTION 8.6 Tax-free Treatment. Prior to the Effective Time, each party
shall use its best efforts to cause (i) the VoiceStream Merger to qualify as a
reorganization described in Section 368(a) of the Code and/or as an exchange
described in Section 351 of the Code and (ii) the Omnipoint Merger, taken
together with the VoiceStream Merger and the Hutchison Transaction, to qualify
as an exchange described in Section 351 of the Code, to obtain the opinions of
counsel referred to in Sections 9.2(b), 9.2(c) and 9.3(b), including the
execution of the letters of representation referred to therein, and will not

Agreement, Omnipoint shall deliver to VoiceStream a letter identifying all known
Persons who may be deemed "affiliates" of Omnipoint under Rule 145 of the 1933

obtain a written agreement from each Omnipoint Rule 145 Affiliate as soon as
practicable and, in any event, at least 30 days prior to the Effective Time,
substantially in the form of Exhibit B hereto. Holding Company shall be entitled
to place legends as specified in such Omnipoint Rule 145 Affiliate letters on
the certificates evidencing any Holding Company Common Stock to be received by

its stockholders, but only if (i) the Board of Directors of Omnipoint determines

outside counsel that it must take such action in order for the Board of
Directors to comply with its fiduciary duties under applicable Delaware Law,
(ii) Omnipoint shall have delivered to VoiceStream three business days' prior

Agreement and supersedes all prior agreements and understandings, both oral and
written, between the parties with respect to the subject matter of this

in any manner materially adverse to any party. Upon such a determination, the

latter section of the Disclosure Schedule or section of the Agreement being
apparent on the face of the information disclosed in the Disclosure Schedule.
The fact that any item of information is disclosed in a Disclosure Schedule to
