member of the Board; and (ii) 4,500,000 Shares, then in such event, Hutchison
PCS and its Permitted Affiliate Transferees shall not be entitled to designate

DT has Transferred all of its Shares to Permitted Affiliate Transferees of DT,

                  (G) Any vacancies on the Board created by reason of the
provisions of subsections (A) through (F) above shall be filled by the vote of a
majority of the directors then in office (unless such directors determine to
reduce the size of the Board after a vacancy is created) to serve until the next
annual meeting of shareholders of VoiceStream, and at the next annual meeting
shall be filled by a vote of a plurality of all shareholders of VoiceStream
(including the Stockholders and their Permitted Affiliate Transferees);
provided, however, that in the event that the size of the Board shall have
increased by reason of Hutchison PCS having the right to designate additional
director(s) and thereafter Hutchison PCS shall cease to have the right to so
designate such additional director(s), the size of the Board shall be
appropriately reduced and each of the Stockholders (and each of their respective
Permitted Affiliate Transferees ) agrees that it will vote, or cause to be
voted, all of the Shares then Beneficially Owned by it (whether now owned or
hereafter acquired), in person or by proxy (and, shall take all other necessary

                  Section 7. Termination. This Agreement shall terminate upon
the earliest to occur of any of the following events:

                  (a) Upon agreement by all Stockholders then retaining the

Designees are to be designated or are serving pursuant to Section 3(a)(v)
hereof, by the Omnipoint Designees or the Old Omnipoint Board; or

                  (b) The filing by VoiceStream of a petition in bankruptcy or
the expiration of sixty (60) days after a petition in bankruptcy shall have been
filed against VoiceStream and such petition shall not have been stayed or
discharged during such sixty (60) day period; or upon the expiration of sixty
(60) days after the commencement of any proceeding under any law for the relief
of debtors seeking the relief or readjustment of VoiceStream's indebtedness
either through reorganization, winding-up, extension or otherwise, and such
proceedings involving VoiceStream as debtor shall not have been vacated or

dissolution of VoiceStream; or

                  (c) The Beneficial Ownership of all of the Shares by only one
Stockholder (including its Permitted Affiliate Transferees).

                  Upon such termination, except for any rights any party may
have in respect of any breach by any other party of its or his obligations
hereunder, none of the parties hereto shall have any further obligation or
liability hereunder.

                  Section 8. Miscellaneous.

                  (a) This Agreement shall be binding upon and inure to the
benefit of the parties hereto and their Permitted Affiliate Transferees. Each of
the Stockholders hereby agrees that prior to any Transfer of any Shares to a
Permitted Affiliate Transferee, such Permitted Affiliate Transferee shall
execute a counterpart of this Agreement agreeing to be bound by the provisions
of this Agreement. No Transfer to a Permitted Affiliate Transferee shall be
effective unless such Permitted Affiliate Transferee has executed such
counterpart of this Agreement. Except as set forth above with respect to
Transfers to Permitted Affiliate Transferees, nothing in this Agreement shall
prohibit the Transfer of Shares by any of the Stockholders.

                  (b) Each of the parties hereto acknowledges and agrees that,
in the event of any breach of this Agreement, the non-breaching parties would be
irreparably harmed and could

                                       10
<PAGE>


not be made whole by monetary damages. Accordingly, each of the parties hereto
agrees that the other parties, in addition to any other remedy to which they may
be entitled at law or in equity, shall be entitled to compel performance of this
Agreement pursuant to Section 8(m).

                  (c) The headings in this Agreement are for convenience only
and shall not be considered a part of or affect the construction or
interpretation of any provision of this Agreement.

                  (d) All notices, requests, demands and other communications
hereunder shall be in writing and shall be deemed to have been duly given if
delivered by same day or next day (or equivalent with respect to delivery
outside the United States) courier (guaranteed delivery) or telex or facsimile
(i) if to a Stockholder, at such Stockholder's address appearing on Schedule I
hereto or at any other address that such Stockholder may have provided in
writing to VoiceStream and the other Stockholders then party to this Agreement
and (ii) if to VoiceStream, at 3650 131st Avenue SE, Bellevue, Washington 98006,
U.S.A., Tel: 425-586-8014, Fax: 425-586-8080; Attention: Alan R. Bender, Esq. or
such other address as VoiceStream may have furnished to the Stockholders in
writing, with a copy (which shall not constitute notice) to Friedman Kaplan &
Seiler LLP, 875 Third Avenue, New York, NY 10022, USA, Tel: 212-833-1107, Fax:
212-355-6401, Attention: Barry A. Adelman, Esq. If a notice hereunder is
transmitted by confirmed fax so as to arrive during normal business hours during
a Business Day at the place of receipt, then such notice shall be deemed to have
been given on such Business Day at the place of receipt or, if so transmitted to
arrive after normal business hours during a Business Day at the place of
receipt, then such notice shall be deemed to have been given on the following
Business Day at the place of receipt. If such notice is sent by next-day courier
or equivalent, it shall be deemed to have been given on the third Business Day
at the place of receipt following sending provided, that the date of sending
shall be deemed to be the date at the place of receipt at the time such notice
is posted.

                  (e) The provisions of this Agreement shall apply, to the full
extent set forth herein with respect to the Shares now or hereinafter owned by
each Stockholder (and its Permitted Affiliate Transferees), to any and all
securities of VoiceStream or any successor or assign of VoiceStream (whether by
merger, consolidation or otherwise) that may be issued in respect of, in
exchange for, or in substitution of such Shares, and shall be appropriately
adjusted for any stock dividends, stock splits, reverse splits, combinations,
recapitalizations and similar events occurring after the date hereof.

                  (f) Copies of this Agreement will be available for inspection
or copying by any interested Person at the offices of VoiceStream through the
Secretary of VoiceStream. VoiceStream will otherwise take all actions as may be
necessary or appropriate to comply with any applicable law relating to the
validity and enforceability of shareholders agreements containing the provisions
of this Agreement.

                  (g) Except as expressly provided otherwise herein, neither
this Agreement nor any provision hereof may be changed, waived, discharged or
terminated orally, but only by an instrument in writing signed by VoiceStream
and each of the Stockholders. The failure of any party hereto to give notice of
the breach or non-fulfillment of any term or condition of this Agreement shall
not constitute a waiver thereof, nor shall the waiver of any breach or
non-

                                       11
<PAGE>


fulfillment of any term or condition of this Agreement constitute a waiver of
any other breach or non-fulfillment of that term or condition or any other term
or condition of this Agreement.

                  (h) This Agreement may be amended or modified at any time by a
writing setting forth such amendment or modification, signed by VoiceStream and
by Stockholders (or their Permitted Affiliate Transferees) owning in the
aggregate at least 90% of the Shares owned by the Stockholders (and their
Permitted Affiliate Transferees); provided, however, that, unless such amendment
is signed by VoiceStream and by each Stockholder (or its Permitted Affiliate
Transferees) adversely affected by such amendment, no such amendment or
modification shall eliminate any right of any Stockholder (or its Permitted
Affiliate Transferees) or, in the case of the Omnipoint Designees, the Old
Omnipoint Board, to designate the member or members of the Board it is entitled
to designate in accordance with Section 3 hereof (it being understood and agreed
that this clause shall not prohibit the enlargement of the Board).

                  (i) This Agreement may be executed in any number of
counterparts, each of which shall be deemed an original, and all of which
together shall be considered one and the same agreement.

                  (j) The obligations of each of the Stockholders under this
Agreement shall be several with respect to each such Stockholder.

                  (k) This Agreement constitutes the entire understanding of the
parties hereto with respect to this subject matter hereof and supersedes all
prior understandings among such parties with respect to such subject matter.

                  (l) The validity of this Agreement, its construction,
interpretation and enforcement, and the rights of the parties hereunder, shall
be determined under, governed by and

construed in accordance with the internal laws of the State of New York
applicable to contracts formed and performed entirely in such state. Each party
hereto agrees that, subject to Section 8(m) hereof, any suit, action or other
proceeding arising out of this Agreement shall be brought and litigated in the
courts of the State of Washington or the United States District Court for the
Western District of Washington and each party hereto hereby irrevocably consents
to personal jurisdiction and venue in any such court and hereby waives any claim
it may have that such court is an inconvenient forum for the purposes of any
such suit, action or other proceeding.

                  (m) Any and all disputes, controversies or claims (each a
"Dispute") between the Stockholders relating to the interpretation or
enforcement or performance of this Agreement shall be resolved by binding
arbitration by the American Arbitration Association in accordance with its
rules, subject to the following provisions:

                  (i) There shall be three arbitrators (the "Arbitrators") which
shall be appointed in accordance with the procedure of the American Arbitration
Association.

                  (ii) The expenses of the arbitration shall be borne equally by
the Stockholders involved in the arbitration, and each party shall bear its own
legal fees and expenses; provided, however, that the Arbitrators shall have
discretion to require that one party pay all or a portion of the expenses of
arbitration or the other party's legal fees and expenses in connection with any
particular arbitration.

                                       12
<PAGE>


                  (iii) The Arbitrators shall determine whether and to what
extent any party shall be entitled to damages or equitable relief. No party
shall be entitled to punitive damages or consequential damages or shall be
required to post a bond in connection with equitable relief.

                  (iv) The Arbitrators shall not have the power to add to nor
modify any of the terms or conditions of this Agreement. The Arbitrators'
decision shall not go beyond what is necessary for the interpretation and
application of the provisions of this Agreement in respect of the issue before
the Arbitrators. The Arbitrators' decision and award or permitted remedy, if
any, shall be based upon the issue as drafted and submitted by the respective
parties and the relevant and competent evidence adduced at the hearing(s).

                  (v) The Arbitrators shall have the authority to award any
remedy or relief provided for in this Agreement, in addition to any other remedy
or relief (including provisional remedies and relief) that a court of competent
jurisdiction could order or grant (but subject to the remedial limitations,
elsewhere set forth in this Agreement, including, but without limitation, the
aforesaid prohibition against punitive and consequential damages). The
Arbitrators written decision shall be rendered within sixty (60) days of the
hearing. The decision reached by the Arbitrators shall be final and binding upon
the parties as to the matter in dispute. To the extent that the relief or remedy
granted by the Arbitration is relief or remedy on which a court could enter
judgment, a judgment upon the award rendered by the Arbitrators may be entered
in any court having jurisdiction thereof (unless in the case of an award of
damages, the full amount of the award is paid within ten (10) days of its
determination by the Arbitrators). Otherwise, the award shall be binding on the
parties in connection with their continuing performance of this Agreement and in
any subsequent arbitral or judicial proceeding between the parties.

                  (vi) The arbitration shall take place in Seattle, Washington,
unless otherwise agreed by the parties, and shall be conducted in the English
language.

                  (vii) The arbitration proceeding and all filing, testimony,
documents and information relating to or presented during the arbitration
proceeding shall be disclosed exclusively for the purpose of facilitating the
arbitration process and for no other purpose.

                  (viii) The parties shall continue performing their respective
obligations under this Agreement notwithstanding the existence of a Dispute
while the Dispute is being resolved unless and until such obligations are
terminated, expire or are suspended in accordance with the provisions hereof.

                  (ix) The Arbitrators may, in their sole discretion, order a
pre-hearing exchange of information including production of documents, exchange
of summaries of testimony or exchange of statements of position, and shall
schedule promptly all discovery and other procedural steps and otherwise assume
case management initiative and control to effect an efficient and expeditious
resolution of the Dispute. At any oral hearing of evidence in connection with an
arbitration proceeding, each party and its counsel shall have the right to
examine its witnesses and to cross-examine the witnesses of the other party. No
testimony of any witness shall be presented in written form unless the opposing
party or parties shall have the opportunity to cross-examine such witness,
except as the parties otherwise agree in writing.

                                       13
<PAGE>


                  (x) Notwithstanding the dispute resolution procedures
contained in this Section 8(m), either party may apply to any court having
jurisdiction (a) to enforce this Agreement to arbitrate, (b) to seek provisional
injunctive relief so as to maintain the status quo until the arbitration award
is rendered or the Dispute is otherwise resolved, or (c) to challenge or vacate
any final judgment, award or decision of the Arbitrators that does not comport
with the express provisions of this Section 8(m).

                  (n) The failure of any party to seek redress for violation of,
or to insist upon the strict performance of , any provision of this Agreement
shall not prevent a subsequent act, which would have originally constituted a
violation, from having the effect of an original violation.

                  (o) The rights and remedies provided by this Agreement are
cumulative and the use of any one right or remedy by any party shall not
preclude or waive its right to use any or all other remedies except as otherwise
expressly provided in this Agreement. Such rights and remedies are given in
addition to any other rights the parties may have by law, statute, ordinance or
otherwise.

                  (p) The invalidity or unenforceability of any particular
provision of this Agreement shall not affect the other provisions hereof, and
this Agreement shall be construed in all respects as if such invalid or
unenforceable provision were omitted.
