                   NOTICE OF SPECIAL MEETING OF STOCKHOLDERS

                        TO BE HELD ON FEBRUARY 24, 2000


To the Stockholders of
East/West Communications, Inc.:


     A special meeting of stockholders of East/West Communications, Inc. will be
held on February 24, 2000 at 4:00 p.m., local time, at Indian Harbor Yacht Club,
710 Steamboat Road, Greenwich, CT 06830, for the following purposes:


     To consider and vote upon a proposal to approve and adopt an Agreement and
     Plan of Merger, dated as of October 22, 1999, between East/West and
     Omnipoint pursuant to which, among other things, East/West will merge with
     and into Omnipoint, which will be the surviving corporation in the merger.

     To transact such other business as may properly be brought before the
     special meeting or any adjournment or postponement of the special meeting.

     East/West's board of directors has unanimously approved the East/West
merger agreement and recommends that you vote FOR approval and adoption of the
East/West merger agreement. We have described the proposal in more detail in the
accompanying proxy statement/prospectus, which you should read in its entirety
before voting. A copy of the East/West merger agreement is attached as Annex A
to the accompanying proxy statement/prospectus.


     The close of business on December 28, 1999 has been fixed by East/West's
board of directors as the record date for the determination of stockholders
entitled to notice of and to vote at the East/West special meeting or any
adjournment or postponement thereof. Only holders of record of East/West common
stock at the close of business on the record date may vote at the East/West
special meeting.


     The approval and adoption of the East/West merger agreement will require
the affirmative vote of the holders of a majority of the voting power of the
shares of East/West common stock outstanding on the record date.

     All stockholders of East/West are cordially invited to attend the East/West
special meeting in person. However, to ensure your representation at the

envelope. You may revoke your proxy in the manner described in the accompanying
joint proxy statement/prospectus at any time before it is voted at the East/West
special meeting. Executed proxies with no instructions indicated thereon will be
voted "FOR" approval and adoption of the merger agreement. If you fail to return
a properly executed proxy card or to vote in person at the East/West special
meeting, the effect will be a vote against the merger agreement.

                                          By Order of the Board of Directors

                                          East/West Communications, Inc.

                QUESTIONS AND ANSWERS ABOUT THE EAST/WEST MERGER

Q: WHAT WILL EAST/WEST STOCKHOLDERS RECEIVE IN THE EAST/WEST MERGER?

A: The consideration that you will receive will depend on whether:

      - the East/West merger is completed immediately prior to the VoiceStream
        reorganization;

      - the East/West merger is completed after the VoiceStream reorganization;
        or

      - the VoiceStream reorganization agreement has been terminated prior to
        the East/West merger.

   Under the scenarios described above:


      - If the East/West merger is completed immediately prior to the
        VoiceStream reorganization, you will receive for each share of East/West
        common stock you hold one share of newly authorized Omnipoint Series E
        preferred stock. In the VoiceStream reorganization, each share of
        Omnipoint Series E preferred stock you received will be converted into
        the "standard election consideration," which is 0.825 shares of common
        stock of VoiceStream Holdings and $8.00 in cash, multiplied by a
        conversion ratio equal to 1,775,000 divided by the number of shares of
        East/West common stock outstanding immediately prior to completion of
        the East/ West merger. There are currently 4,839,374 shares of East/West
        common stock outstanding. You will be paid cash for fractional shares.


        For example:


        For each share of East/West common stock that you hold, you will receive
        one share of Omnipoint Series E preferred stock. If there are 4.84
        million shares of East/West common stock outstanding immediately prior
        to the East/West merger, in the VoiceStream reorganization, you will
        receive approximately .30 shares of VoiceStream Holdings common stock
        and approximately $2.93 for each share of East/West common stock that
        you hold.



      - If the East/West merger is completed after the VoiceStream
        reorganization, for each share of East/West common stock that you hold,
        you will receive the standard election consideration, multiplied by the
        conversion ratio described above. You will be paid cash for fractional
        shares.



        For example:



        If there are 4.84 million shares of East/West common stock outstanding
        immediately prior to the East/West merger, for each share of East/West
        common stock that you hold, you will receive approximately .30 shares of
        VoiceStream holdings common stock and approximately $2.93.



      - If the VoiceStream reorganization agreement is terminated prior to
        completion of the East/West merger, for each share of East/West common
        stock that you hold, you will receive one share of Omnipoint common
        stock multiplied by the conversion ratio described above. You will be
        paid cash for fractional shares.


        For example:


        If there are 4.84 million shares of East/West common stock outstanding
        immediately prior to the East/West merger, for each share of East/West
        common stock that you hold, you will receive approximately 0.3668 shares
        of Omnipoint common stock.


Q: WHEN DO YOU EXPECT THE EAST/WEST MERGER TO BE COMPLETED?


A: We are working toward completing the East/West merger as quickly as possible.
   We expect to complete the East/West merger in February 2000.


Q: IS THE CLOSING OF THE EAST/ WEST MERGER CONDITIONED ON THE VOICESTREAM
REORGANIZATION?

A: The closing of the East/ West merger is not conditioned on the closing of the
   VoiceStream reorganization.

<PAGE>   9

Q: WHEN IS THE VOICESTREAM REORGANIZATION GOING TO BE COMPLETED?

A: The VoiceStream reorganization is planned to be completed during the first
   quarter of 2000. However its completion is subject to government and
   stockholder approvals that we do not control. We therefore cannot predict
   with any certainty when the VoiceStream reorganization will be completed.

Q: WHERE CAN I FIND OUT MORE INFORMATION ABOUT THE VOICESTREAM REORGANIZATION?

A: You can find out more information about the VoiceStream reorganization by
   reading the enclosed VoiceStream disclosure statement.

Q: WHAT DO I NEED TO DO NOW?

A: We urge you to read this proxy statement/prospectus carefully, including its
   annexes, and to consider how the East/West merger affects you as a
   stockholder. You also may want to review the documents referenced under
   "Where You Can Find More Information."

Q: HOW DO I VOTE?

A: You should simply indicate on your proxy card how you want to vote, and sign
   and mail your proxy card in the enclosed return envelope as soon as possible
   so that your shares may be represented at the special meeting. If you sign
   and send in your proxy and do not indicate how you want to vote, your proxy
   will be counted as a vote for the East/West merger agreement, except if your
   shares are held in a brokerage account. If you fail to return your proxy card
   or to vote in person at the special meeting, the effect will be a vote
   against the East/West merger agreement.

Q: IF MY SHARES ARE HELD IN A BROKERAGE ACCOUNT, WILL MY BROKER VOTE MY SHARES
FOR ME?

A: Your broker will not vote your shares for you unless you provide instructions
   on how to vote. It is important therefore that you follow the directions
   provided by your broker regarding how to instruct your broker to vote your
   shares.

Q: MAY I CHANGE MY VOTE AFTER I HAVE MAILED MY PROXY CARD?

A: Yes. You may change your vote at any time before your proxy is voted at the
   special meeting. You may do this in one of three ways. First, you may send a
   written notice stating that you would like to revoke your proxy. Second, you
   may complete and submit a new proxy card. If you choose either of these two
   methods, you must submit your notice of revocation or your new proxy card to
   East/West at the address on page 3. Third, you may attend the special meeting
   and vote in person. Simply attending the special meeting, without voting in
   person, will not revoke your proxy. If you have instructed a broker to vote
   your shares, you must follow directions received from your broker to change
   your vote or to vote at the special meeting.

Q: SHOULD I SEND IN MY STOCK CERTIFICATES NOW?

A: No. After the East/West merger is completed, we will send you written
   instructions for exchanging your stock certificates.

     The following summary highlights selected information from this document
and may not contain all of the information that is important to you. To
understand the East/West merger fully and for a more complete description of the
legal terms of the East/West merger, you should read carefully this entire
document and the other documents to which we have referred you. See "Where You
Can Find More Information" on page 72. We have included page references
parenthetically to direct you to more complete descriptions of the topics
presented in this summary.


                                 THE COMPANIES

OMNIPOINT CORPORATION
3 Bethesda Metro Center, Suite 400
Bethesda, Maryland 20814
(301) 951-2500

     Omnipoint is a leading provider of personal communications services in the
eastern United States. Omnipoint currently owns and operates fully digital PCS
networks in five major markets. Omnipoint holds 156 broadband PCS licenses.
Omnipoint's licenses, together with licenses held by joint ventures in which it
is an investor, cover approximately 100 million persons. Omnipoint, through its
wholly owned subsidiary, Omnipoint Technologies, Inc., is also a developer and
supplier of wireless communication technologies, products and engineering
services.


     On June 23, 1999, Omnipoint agreed to be acquired by VoiceStream Wireless
Corporation and its wholly owned subsidiary, VoiceStream Wireless Holding
Corporation. Concurrently with the signing of that agreement, Omnipoint,
VoiceStream and entities affiliated with Cook Inlet Region, Inc. and Hutchison
Whampoa Limited entered into a number of other agreements relating to the
VoiceStream reorganization. For additional details concerning these
transactions, see "The VoiceStream Transactions" on page 52.


EAST/WEST COMMUNICATIONS, INC.
350 Stuyvesant Avenue
Rye, New York 10580
(914) 921-6300

     East/West holds five 10-MHz PCS licenses for which it was the high bidder
at an auction conducted by the FCC. The PCS licenses cover two of the top ten
markets in the United States: Los Angeles, California, and Washington, D.C., as
well as the Sarasota, Florida, Reno, Nevada, and Santa Barbara, California
markets, representing a total population of approximately 21 million people.
East/ West bid a total of approximately $19 million for the PCS licenses, after
a 25% credit given to small businesses. Eighty percent of the total cost of the
PCS licenses, or $15.2 million, was financed over a ten-year period, with
interest only payments due during the first two years.


                         THE EAST/WEST MERGER (Page 27)


     The East/West merger agreement is attached to this proxy
statement/prospectus as Annex A. We encourage you to read the agreement as it
governs the East/West merger. Upon the consummation of the East/West merger,
East/West will merge with and into Omnipoint, and Omnipoint will continue as the
surviving corporation. The East/West merger will become effective upon the
filing of the Certificate of Merger with the Secretary of State of the State of
Delaware.

          WHY OMNIPOINT AND EAST/WEST ARE PROPOSING TO MERGE (Page 28)


     Omnipoint believes that the proposed merger with East/West is an attractive
opportunity for it to acquire FCC licenses in key markets. East/West believes
that the proposed merger with Omnipoint presents its stockholders with the
opportunity to become stockholders of a substantially larger and more
diversified company.


                     THE VOICESTREAM TRANSACTIONS (Page 52)



     On June 23, 1999, Omnipoint announced its proposed combination with
VoiceStream in a cash and stock transaction, subject to the receipt of
stockholder and regulatory approvals and other customary closing conditions. We
have included the VoiceStream disclosure statement and the annexes and exhibits
thereto with respect to the VoiceStream reorganization. We encourage you to read
the VoiceStream disclosure statement and "The VoiceStream Transactions" on page
52.



THE EFFECT OF THE VOICESTREAM TRANSACTIONS ON THE EAST/WEST STOCKHOLDERS (Pages
                                     52-58)



     You will become a stockholder of VoiceStream Holdings if (i) the
VoiceStream reorganization occurs after the East/West merger or (ii) the
VoiceStream reorganization occurs and the East/West merger occurs after the
VoiceStream reorganization. You are therefore strongly encouraged to review the
enclosed VoiceStream disclosure statement.



                            VOTES REQUIRED (Page 13)


     The holders of a majority of the voting power of the outstanding shares of
East/West common stock must vote in favor of the East/West merger agreement to
approve the East/West merger. The approval of the stockholders of Omnipoint is
not required.


     Aer Force Communications, Inc. owns approximately 81.6% of the outstanding
voting power of all shares of East/West common stock entitled to vote at the
East/West special meeting, and has agreed under a voting agreement to vote in
favor of the East/West merger agreement. For a description of the voting
agreement, see page 42. The directors and officers of East/West and their
affiliates, including Aer Force Communications, as a group, beneficially own
approximately 85.6% of the outstanding voting power of all shares of East/West
common stock entitled to vote at the East/West special meeting.



     EAST/WEST BOARD OF DIRECTORS RECOMMENDATION TO STOCKHOLDERS (Page 28)


     The East/West board of directors voted unanimously to approve the East/West
merger agreement. The East/West board believes that the East/West merger is in
your best interests and recommends that you vote FOR the proposal to approve the
East/West merger agreement.


         INTERESTS OF CERTAIN PERSONS IN THE EAST/WEST MERGER (Page 30)


     In considering the recommendation of the East/West board of directors, you
should be aware that some directors and executive officers of East/West have
interests in the East/West merger that are in addition to, or different from,
the interests of holders of East/West common stock generally. In addition, the
merger agreement also provides for indemnification of directors and officers of
East/West for liabilities relating to matters occurring prior to the effective
time of the East/West merger.

<PAGE>   13


                         REGULATORY APPROVALS (Page 31)


     To complete the East/West merger, we must make filings with and receive
authorizations from various federal and state governmental agencies in the
United States, including the FCC. These filings relate to antitrust matters and
FCC regulations governing the transfer and assignment of East/West's PCS
licenses in the East/West merger.

     It is possible that some of these governmental authorities may impose
conditions for granting approval. We cannot predict whether we will obtain all
of the required approvals within the time frame contemplated by the East/West
merger agreement.


                  CONDITIONS TO THE EAST/WEST MERGER (Page 49)


     The completion of the East/West merger depends upon the satisfaction or
waiver of many conditions, including:

     - the approval of the East/West stockholders;


     - absence of legal prohibition on completion of the East/West merger or the
       other transactions provided for in the East/West merger agreement;


     - effectiveness of all governmental consents without limitations,
       restrictions or obligations that would have a material adverse effect on
       the business operations of East/West or Omnipoint;

     - effectiveness of Omnipoint's registration statement on Form S-4;

     - receipt of opinions of counsel relating to tax, corporate and regulatory
       matters;

     - receipt of all requisite approvals of the FCC which shall not contain any
       conditions with respect to East/West or Omnipoint, which conditions would
       be reasonably expected to have a material adverse effect on Omnipoint;

     - each of the parties to a supplemental agreement shall have performed its
       respective obligations and Omnipoint and East/West shall have received a

       VoiceStream reorganization shall have been satisfied and the parties to

       VoiceStream reorganization immediately after the closing of the East/West
       merger; (ii) the VoiceStream reorganization agreement shall have been
       terminated; or (iii) the closing of the VoiceStream reorganization shall
       have occurred;


     - accuracy as of closing of the representations and warranties made by the
       parties to the extent specified in the East/West merger agreement; and

     - performance in all material respects by the parties of their obligations
       required to be performed at or prior to closing.

     ADDITIONAL OMNIPOINT CONDITIONS

     Omnipoint's obligation to complete the East/West merger is also conditioned
upon the following:

     - no more than 10% of East/West stockholders exercise dissenters' rights;
       and

     - the requisite approval from the FCC shall have become a final order and
       shall not contain any conditions with respect to Omnipoint or East/West,
       which conditions would be reasonably expected to have a material adverse
       effect on Omnipoint.

            TERMINATION OF THE EAST/WEST MERGER AGREEMENT (Page 50)


     The East/West merger agreement may be terminated under certain conditions,
including:

     - by mutual written consent of East/West and Omnipoint;

     - by either East/West or Omnipoint if:

        - the East/West merger has not been consummated by July 31, 2000, which
          may under some circumstances be extended to October 22, 2000, unless a
          willful breach by the terminating party caused the failure to timely
          complete the East/West merger;

        - there is a permanent legal prohibition to closing the East/West
          merger; or

        - any of the conditions to the terminating party's obligation to

     - by Omnipoint if:

        - the East/West board fails to recommend, or withdraws or modifies its

          all material respects, its obligations under the East/West merger
          agreement, and East/West is incapable of satisfying, in all material
          respects, its obligations under the East/West merger agreement by
          October 22, 2000;

        - East/West updates information on its disclosure schedules to the
          East/West merger agreement and such change(s) result in a material
          adverse effect on East/West or Omnipoint;

     - by East/West if:

        - Omnipoint willfully and materially breaches any of its
          representations, warranties, covenants or agreements;

        - Omnipoint breaches any of its representations, warranties, covenants
          or agreements that would cause Omnipoint to be incapable of
          satisfying, in all material respects, its obligations under the
          East/West merger agreement, and Omnipoint is incapable of satisfying,
          in all material respects, its obligations under the East/West merger
          agreement by October 22, 2000;

        - Omnipoint updates information on its disclosure schedules to the
          East/West merger agreement and such change(s) result in a material

          Holdings takes actions that are inconsistent with the other provisions
          of the East/West merger agreement, or fails to take certain other
          actions, in order to consummate the VoiceStream reorganization,
          fulfill the closing conditions in the VoiceStream reorganization
          agreement, or to ensure that the receipt of VoiceStream Holdings
          common stock by Omnipoint stockholders pursuant to the VoiceStream
          reorganization will be tax-free to such Omnipoint stockholders;

        MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES (Page 32)


     The East/West merger is generally intended to qualify as a reorganization
under Section 368(a) of the Internal Revenue Code. If the East/West merger
constitutes a reorganization within the meaning of the Internal Revenue Code, no
gain or loss will be recognized by holders of East/West common stock, except to
the extent of cash received. As described in more detail under the heading "The
East/West Merger Agreement -- Material United States Federal Income Tax
Consequences of the East/West Merger," it is possible that the East/West merger
will be completed even if it does not qualify as a reorganization under Section
368(a) of the Internal Revenue Code. In this case, the East/West merger will be
a fully taxable transaction and holders of East/West common stock will recognize
gain or loss in an amount equal to the difference between the fair market value
of the consideration received in the East/West merger and the holder's adjusted
tax basis in the stock exchanged therefor.

     Tax matters are very complicated, and the tax consequences of the East/West
merger to you will depend on the facts of your own situation. You should consult
your tax advisor for a full understanding of the tax consequences of the
East/West merger to you. We encourage you to review carefully the disclosure
under the heading "The East/West Merger Agreement -- Material United States
Federal Income Tax Consequences of the East/West Merger."


                         ACCOUNTING TREATMENT (Page 30)


     For accounting and financial reporting purposes, the East/West merger will
be accounted for using the purchase method of accounting with Omnipoint becoming
the successor company to East/West.


                   DISSENTERS' RIGHTS OF APPRAISAL (Page 39)


     Under the Delaware General Corporation Law, the holders of East/West common
stock and preferred stock have the right to seek an appraisal of, and to be paid
the fair value of, their shares. Section 262 of the Delaware General Corporation
Law, which governs the rights of stockholders who wish to seek appraisal of
their shares, is summarized under the heading "The East/West Merger --
Dissenters' Rights of Appraisal" on page 38, and is attached to this proxy
statement/prospectus as Annex B.

- -------------------------
(1) EBITDA represents operating income (loss) before depreciation and
    amortization. EBITDA should not be considered as an alternative to, or more
    meaningful than, operating income (loss) as determined in accordance with
    GAAP, cash flows from operating activities (as determined in accordance with
    GAAP), or as a measure of liquidity. Management of Omnipoint believes EBITDA
    provides meaningful additional information on its operating results and on
    its ability to service its long-term debt and other fixed obligations and to
    fund its continuing growth. Because EBITDA is not calculated in the same
    manner by all companies, the presentation herein may not be comparable to
    other similarly titled measures of other companies.

(2) Represents population to which Omnipoint's consolidated systems were
    marketed at period end.

                         THE EAST/WEST SPECIAL MEETING

DATE, TIME, AND PLACE


     The special meeting of East/West stockholders will be held at 4:00 p. m.,
local time, on February 24, 2000, at Indian Harbor Yacht Club, 710 Steamboat
Road, Greenwich, CT 06830. This proxy statement/prospectus is being furnished in
connection with the solicitation by the board of directors of East/West of
proxies to be used at the East/West special meeting and at any and all
adjournments and postponements of the East/West special meeting.


PURPOSE

     The purpose of the East/West special meeting is to consider and vote on the
proposal to approve the East/West merger agreement under which East/West would
be merged with and into Omnipoint with Omnipoint continuing as the surviving
corporation. Omnipoint has also entered into a separate agreement with
VoiceStream under which Omnipoint and VoiceStream would each become a wholly-
owned subsidiary of VoiceStream Wireless Holding Corporation. East/West
stockholders may also be asked to transact other business that may properly come
before the East/West special meeting or any adjournment or postponement of the
East/West special meeting.

EAST/WEST BOARD OF DIRECTORS' RECOMMENDATION

     The East/West board, after careful consideration, has unanimously approved
the East/West merger agreement and recommends a vote FOR approval of the
East/West merger agreement.

RECORD DATE, OUTSTANDING SHARES AND VOTING RIGHTS


     The East/West board has fixed December 28, 1999 as the record date for the
East/West special meeting. Only holders of record of shares of East/West common
stock on the record date are entitled to notice of and to vote at the East/West
special meeting. As of the record date, there were 4,739,374 outstanding shares
of East/West common stock held by approximately 2,150 holders of record. At the
East/West special meeting, holders of shares of East/West Class A common stock
will be entitled to one vote per share of East/West Class A common stock and
holders of shares of East/West Class B common stock will be entitled to five
votes per share of East/West Class B common stock. Holders of East/West Class A
common stock can vote no more than 49.9% of East/West's voting interests.
Holders of East/ West Class B common stock have the right to vote at least 50.1%
of East/West's voting interests.


VOTE REQUIRED; QUORUM

     The approval of the East/West merger agreement will require the affirmative
vote of the holders of a majority of the voting power of the shares of East/West
Class A common stock and East/West Class B common stock, voting together as one
class, provided that, in accordance with the Certificate of Incorporation and
Bylaws of East/West, the holders of Class B common stock shall always represent
at least 50.1% of the voting power of East/West.

     The representation, in person or by properly executed proxy, of the holders
of a majority of the voting power of the shares of stock entitled to vote at the
East/West special meeting is necessary to constitute a quorum at the East/West
special meeting. Shares of East/West common stock represented in person or by
proxy will be counted for the purposes of determining whether a quorum is
present at the East/West special meeting. Shares that abstain from voting on the
proposal to approve the East/West merger agreement will be treated as shares
that are present and entitled to vote at the East/West special meeting for
purposes of determining whether a quorum exists, but abstentions will have the
same effect as votes against approval of the East/West merger agreement. Broker
non-votes will be treated as present and entitled to vote at the East/West
special meeting for purposes of determining whether a quorum exists. Brokers or
nominees holding shares of record for customers will not be entitled to vote on
the proposal to approve the merger agreement unless they receive voting
instructions from their customers.

                                       13
<PAGE>   21

Accordingly, broker non-votes will not be voted in favor of approval of the
East/West merger agreement meaning that such shares will have the same effect as
shares voted against approval of the East/West merger agreement.


     As of the record date, East/West's directors and executive officers and
their affiliates beneficially owned approximately 85.6% of the votes represented
by the outstanding shares of East/West common stock. East/West's directors and
executive officers have expressed their intent to vote their shares in favor of
approval of the East/West merger agreement.



     At the time the East/West merger agreement was executed by East/West and
Omnipoint, Aer Force Communications, Inc., holder of approximately 81.6% of the
votes entitled to be cast by holders of all outstanding shares of East/West
common stock, entered into a voting agreement with East/West and Omnipoint under
which Aer Force agreed to vote in favor of approval of the East/West merger
agreement.


VOTING OF PROXIES

     All shares of East/West common stock that are entitled to vote and are
represented at the East/West special meeting by properly executed proxies
received prior to or at such meeting, and not revoked, will be voted at such
meeting in accordance with the instructions indicated on such proxies. If no
instructions are indicated, such proxies, other than broker non-votes, will be
voted for approval of the East/West merger agreement.

     The East/West board does not know of any matters other than those described
in the notice of the East/West special meeting that are to come before such
meeting. If any other matters are properly presented at the East/West special
meeting for consideration, including, among other things, consideration of a
motion to adjourn or postpone such meeting to another time and/or place for the
purposes of soliciting additional proxies or allowing additional time for the
satisfaction of conditions to the East/West merger, the persons named in the
enclosed form of proxy and acting thereunder generally will have discretion to
vote on such matters in accordance with their best judgment. Notwithstanding the
foregoing, proxies voted against the East/West merger will not be voted in favor
of any adjournment or postponement of the special meeting for the purpose of
soliciting additional proxies.

REVOCATION OF PROXIES

     Any proxy given pursuant to this solicitation may be revoked by the person
giving it at any time before it is voted. Proxies may be revoked by:

     - filing with the Secretary of East/West, at or before the taking of the
       vote at the East/West special meeting, a written notice of revocation
       bearing a later date than the proxy;

     - duly executing a later-dated proxy relating to the same shares and
       delivering it to the Secretary of East/West before the taking of the vote
       at the East/West special meeting; or

     - attending the East/West special meeting and voting in person, although
       attendance at the East/ West special meeting will not in and of itself
       constitute a revocation of a proxy.

     Any written notice of revocation or subsequent proxy should be sent to
East/West Communications, Inc., 350 Stuyvesant Avenue, Rye, New York 10580
Attention: Secretary, or hand delivered to the Secretary of East/West at or
before the taking of the vote at the East/West special meeting. Stockholders
that have instructed a broker to vote their shares must follow directions
received from such broker in order to change their vote or to vote at the
East/West special meeting.

SOLICITATION OF PROXIES; EXPENSES

     Substantially all expenses of East/West's solicitation of proxies,
including the cost of preparing and mailing this joint proxy
statement/prospectus to East/West stockholders, will be borne by East/West. In
addition to solicitation by use of the mails, proxies may be solicited from
East/West stockholders by directors, officers, and employees of East/West in
person or by telephone, facsimile, or other means of communication. Such
directors, officers, and employees will not be additionally compensated, but may
be reimbursed for reasonable out-of-pocket expenses in connection with such
solicitation. East/West has not retained a proxy solicitation firm to assist
East/West in connection with the solicitation of proxies for the East/West
special meeting.

                                  RISK FACTORS

     In evaluating the transactions described in this proxy statement/prospectus
you should carefully consider the risks identified below. Additional risks not
presently known to Omnipoint or that it currently deems immaterial may also
impair Omnipoint's business operations.

     In addition to considering the risks described below, you should also
carefully consider the risk factors identified and described in the VoiceStream
disclosure statement, a copy of which is enclosed with this proxy
statement/prospectus. While you will not be entitled to vote on the approval of
the VoiceStream reorganization, you should consider them carefully in light of
the fact that you could become a stockholder of VoiceStream Holdings as a result
of the transactions described in this proxy/prospectus.

RISKS RELATED TO THE EAST/WEST MERGER

     BEFORE APPROVING THE EAST/WEST MERGER AGREEMENT, YOU MUST WEIGH THE RISKS
     OF OWNING SHARES OF OMNIPOINT SERIES E PREFERRED STOCK, OMNIPOINT COMMON
     STOCK, OR VOICESTREAM HOLDINGS COMMON STOCK.

     By approving the East/West merger agreement, every holder of East/West
common stock acknowledges that he or she may receive in the East/West merger an
amount of Omnipoint Series E preferred stock, VoiceStream Holdings common stock,
Omnipoint common stock and/or cash. See "The East/West Merger -- Conversion of
East/West Common Stock." Omnipoint Series E preferred stock or Omnipoint common
stock will be supported by a different mix of assets and personnel than that of
either East/West common stock or Omnipoint common stock prior to the East/West
merger. VoiceStream Holdings common stock will be supported by a different mix
of assets and personnel than that of either East/West common stock, Omnipoint
common stock, or Omnipoint Series E preferred stock. As a consequence, the
Omnipoint Series E preferred stock, VoiceStream Holdings common stock, or
Omnipoint common stock may perform differently than the East/West common stock
has performed historically. Each stockholder must weigh the risks of this new
equity ownership, understanding that the stock price of VoiceStream Holdings
common stock, or Omnipoint common stock may fluctuate significantly after the
East/West merger.

     THE STOCK PRICE OF VOICESTREAM HOLDINGS COMMON STOCK OR OMNIPOINT COMMON
     STOCK MAY FLUCTUATE SIGNIFICANTLY AFTER THE EAST/WEST MERGER.

     There will be no public market for Omnipoint Series E preferred stock.
Omnipoint common stock trades on the Nasdaq Stock Market and VoiceStream
Holdings common stock is expected to be listed and traded on the Nasdaq Stock
Market. The market price of VoiceStream Holdings common stock or Omnipoint
common stock could fluctuate significantly in response to various factors and
events, including:

     - the perceived prospects of the combined companies;

     - changes in VoiceStream Holdings' or Omnipoint's operating results;

     - changes in, or VoiceStream Holdings' or Omnipoint's failure to meet,
       financial estimates by securities analysts;

     - liquidity of VoiceStream Holdings common stock or Omnipoint common stock;
       and

     - developments in the wireless communications industry.

     In addition, the stock market in general and wireless industry stocks in
particular have experienced extreme volatility that often has been unrelated to
the operating performance of particular companies. These broad market and
industry fluctuations may adversely affect the trading price of VoiceStream

                                       16
<PAGE>   24

Holdings common stock or Omnipoint common stock, regardless of VoiceStream
Holdings' or Omnipoint's actual operating performance.

     YOUR ABILITY TO RESELL OMNIPOINT SERIES E PREFERRED STOCK, VOICESTREAM
     HOLDINGS COMMON STOCK, OR OMNIPOINT COMMON STOCK MAY BE RESTRICTED.

     All Omnipoint Series E preferred stock, VoiceStream Holdings common stock
or Omnipoint common stock that East/West stockholders receive as a result of the
East/West merger will be freely transferable, except for Omnipoint Series E
preferred stock, VoiceStream Holdings common stock, or Omnipoint common stock
received by stockholders who are deemed to be "affiliates" of East/West prior to
the merger. Affiliates may resell their Omnipoint Series E preferred stock,
VoiceStream Holdings common stock, or Omnipoint common stock only in
transactions permitted by the resale provisions and volume limitations of Rule
145 or Rule 144 of the Securities Act or as the Securities Act otherwise
permits.

     NEITHER OMNIPOINT NOR EAST/WEST CAN GUARANTEE THAT THE EAST/WEST MERGER
     WILL BE CONSUMMATED.

     Neither Omnipoint nor East/West can give you assurance that the East/West
merger or the VoiceStream reorganization will be consummated. Omnipoint,
VoiceStream, and VoiceStream Holdings have the right to take (or fail to take)
any action necessary in order to consummate the VoiceStream reorganization,
fulfill the closing conditions in the VoiceStream reorganization agreement, or
to ensure that the receipt of VoiceStream Holdings common stock by Omnipoint
stockholders pursuant to the VoiceStream reorganization will be tax-free to such
Omnipoint stockholders, even if such action (or failure to take such action)
will result in the East/West merger not being completed. Failure to consummate
such transactions may result in a material adverse effect on the business or
prospects of East/West. Such a material adverse effect may result from, among
other factors, the significant amount of time and resources that have been
dedicated by the management of East/West to the transactions contemplated by the
East/West merger agreement.

     EAST/WEST MERGER MAY NOT QUALIFY AS A TAX-FREE REORGANIZATION.

     The East/West merger generally is intended to qualify as a reorganization
under Section 368(a) of the Internal Revenue Code. If the East/West merger
constitutes a reorganization within the meaning of the Internal Revenue Code, no
gain or loss will be recognized by holders of East/West common stock, except to
the extent of cash received. As described in more detail under the heading "The
East/West Merger Agreement -- Material United States Federal Income Tax
Consequences of the East/West Merger" it is possible that the East/West merger
will be completed even if it does not qualify as a reorganization under Section
368(a) of the Internal Revenue Code. In this case, the East/West merger will be
a fully taxable transaction and holders of East/West common stock will recognize
gain or loss in an amount equal to the difference between the fair market value
of the consideration received in the East/West merger and the holder's adjusted
tax basis in the stock exchanged therefor.

     Tax matters are very complicated, and the tax consequences of the East/West
merger to you will depend on the facts of your own situation. You should consult
your tax advisor for a full understanding of the tax consequences of the
East/West merger to you. We encourage you to review carefully the disclosure
under the heading "The East/West Merger Agreement -- Material United States
Federal Income Tax Consequences of the East/West Merger".

RISKS RELATED TO OMNIPOINT

     OMNIPOINT HAS A HISTORY OF OPERATING LOSSES, AND ITS FUTURE OPERATING
     RESULTS ARE UNCERTAIN.

     Omnipoint sustained operating losses of approximately $342.9 million for
the nine months ended September 30, 1999, $456.8 million in fiscal 1998, $238.3
million in fiscal 1997 and $100.4 million in fiscal 1996. At September 30, 1999,
Omnipoint had an accumulated deficit of $1.7 billion and negative

                                       17
<PAGE>   25

stockholders' equity, net of accumulated deficit, of $822.6 million. East/West
sustained losses before income taxes of approximately $205,158 for the nine
months ended September 30, 1999, $141,000 in fiscal year 1998, $2,075,000 in
fiscal year 1997 and $3,999,343 for the period from July 26, 1996 (inception) to
September 30, 1999. At September 30, 1999, East/West had a deficit accumulated
during the development stage of approximately $5,554,000 and total shareholders'
equity of approximately $562,000. Omnipoint expects to incur significant
operating losses and to generate negative cash flow from operating activities
during the next several years while it continues to develop and construct its
systems and grow its subscriber base.

     Omnipoint believes that its future operating results over both the short
and long term will be subject to annual and quarterly fluctuations due to
several factors, some of which are outside its control. These factors include,
among others, the following:

     - costs associated with the buildout of Omnipoint's networks (including any
       unanticipated costs associated with this buildout);

     - fluctuations in demand for Omnipoint's services and equipment;

     - the expansion of the market for PCS;

     - increased competition, including price competition;

     - changes in the regulatory environment;

     - the cost and availability of equipment components; and

     - changes in general economic conditions.

     Omnipoint cannot assure you that it will achieve or sustain profitability
or positive cash flow from operating activities in the future, or will generate
sufficient cash flow to service current or future debt requirements or working
capital requirements.

     OMNIPOINT'S SUBSTANTIAL DEBT WILL LIMIT ITS ABILITY TO BORROW ADDITIONAL
     FUNDS TO FINANCE ITS GROWTH, CREATES FINANCIAL AND OPERATING RISKS, AND
     WILL MAKE IT VULNERABLE TO INCREASES IN INTEREST RATES.

     After the East/West merger, Omnipoint will be highly leveraged and subject
to strict financial limitations because Omnipoint and East/West have incurred a
significant amount of debt in acquiring PCS licenses, building their systems and
subscriber bases. As of September 30, 1999, East/West had approximately
$15,166,177 of total outstanding debt and redeemable preferred stock of
$4,528,282. As of November 30, 1999, Omnipoint had approximately $2.9 billion of
total outstanding long-term debt. Omnipoint's level of debt, and the incurrence
of additional debt in the future, could have important consequences to you. For
example, it could:

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

     - limit Omnipoint's flexibility in reacting to changes in Omnipoint's
       business and the wireless industry generally;

     - limit Omnipoint's ability to borrow additional funds due to financial and
       restrictive covenants in such debt; and

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

     Additionally, Omnipoint cannot guarantee that after the closing of the
East/West merger Omnipoint will be able to generate enough cash flow from
operations or that Omnipoint will be able to obtain

                                       18
<PAGE>   26

enough capital to service Omnipoint's debt or fund Omnipoint's planned capital
expenditures. Omnipoint may also need to refinance some or all of Omnipoint's
indebtedness on or before its maturity. Omnipoint cannot guarantee, however,
that Omnipoint will be able to refinance Omnipoint's indebtedness on
commercially reasonable terms or at all. Should Omnipoint be liquidated,
Omnipoint's stockholders' claims would be subordinated to the claims of the
holders of any outstanding indebtedness.

     THE FCC AND OTHER REGULATORY AGENCIES MUST APPROVE THE EAST/WEST MERGER AND
     COULD DELAY OR REFUSE TO APPROVE THE EAST/WEST MERGER OR IMPOSE CONDITIONS
     THAT COULD ADVERSELY AFFECT OMNIPOINT'S BUSINESS OR FINANCIAL CONDITION.

     The Communications Act and FCC rules require the FCC's prior approval of
the assignment of East/West's PCS licenses to Omnipoint. East/West and Omnipoint
filed an application for FCC approval of the assignment of East/West's PCS
licenses to Omnipoint on November 1, 1999. The FCC released a Public Notice
announcing the acceptance for filing of the application. Interested parties will
have until December 10, 1999 to comment on, or to oppose, the application.
Interested parties will again have 30 days to comment on or oppose the grant of
the FCC's consent to the application following public notice of the grant.

     Omnipoint's obligation to close on the East/West merger is conditioned,
among other factors, upon the order granting the requisite FCC consent becoming
final. A "final" FCC order is one that has not been stayed and is no longer
subject to review by the FCC or the courts because the statutory period for
seeking such review has expired without any request for review or stay pending.
Following the FCC's grant of consent, Omnipoint cannot assure you that there
will not be any post-grant challenges by private parties or actions by the FCC
or the courts that would delay or prevent finality. Though Omnipoint may waive
finality as a condition of closing, we cannot assure you that it will do so.

     While Omnipoint expects that the application will be processed in
accordance with the FCC's routine procedures and without conditions other than
conditions that are consistent with those generally applicable to the assignment
of PCS licenses, we cannot assure you that the FCC will grant the application,
that the FCC will grant the application without conditions, or that there will
be no delay caused by the filing of a challenge to the assignment application.

     OMNIPOINT WILL NEED SIGNIFICANT FUTURE FUNDING, WHICH IT MAY NOT BE ABLE TO
     OBTAIN.

     Omnipoint's business plan will require it to obtain significant amounts of
additional capital if either or both of the East/West merger or the VoiceStream
reorganization is completed. Among other things, this additional funding will be
needed for the buildout of Omnipoint's networks. To the extent that the buildout
of these networks is faster than expected, the costs will be greater than
anticipated. Omnipoint's industry is rapidly evolving and is experiencing a
number of recent consolidations. Omnipoint will need significant additional
funding to make any future strategic acquisitions, including those that may
arise through future acquisitions of licenses and equipment for the development
or expansion of its PCS networks. Omnipoint may also need substantial additional
capital to refinance its indebtedness as it matures. There can be no assurance
that Omnipoint will be able to obtain such financing on acceptable terms and in
adequate amounts to accomplish its objectives, if at all. Omnipoint's access to
additional funds may be limited by the terms of its existing financing
arrangements, including:

     - covenants that restrict the amount of additional borrowings that
       Omnipoint can make, including borrowings under existing credit
       facilities;

     - covenants that restrain Omnipoint's ability to grant security interests
       on its assets that diminish its ability to obtain additional secured
       financing; and

     - substantial existing debt service requirements.

                                       19
<PAGE>   27

     Among other things, the amount of Omnipoint's future capital needs will
depend on a variety of factors, including:

     - Omnipoint's desire to pursue strategic opportunities not contemplated by
       its business plan;

     - the level of its buildout costs;

     - greater than anticipated equipment maintenance or replacement costs;

     - expansion of its sales and marketing efforts;

     - the progress of its research and development efforts and the extent to
       which it invests in new technology and in improvements to its existing
       technology; and

     - the response of competitors to its services and equipment.

     Omnipoint plans to meet its additional capital needs for the buildout of
its systems and to refinance its indebtedness as it becomes due with the
proceeds from credit facilities and other borrowings, the proceeds from sales of
additional debt securities, the sale or issuance of equity securities, financing
arrangements with vendors and through joint ventures. Omnipoint cannot guarantee
that it will be able to raise sufficient additional capital on commercially
reasonable terms or at all. If Omnipoint does not raise sufficient funds, it may
delay or abandon some or all of its planned buildout or expenditures, which
could materially limit its ability to compete in the wireless communications
industry. Omnipoint's failure to refinance any indebtedness when due could have
a material adverse effect on its financial condition, results of operations and
cash flows.

     OMNIPOINT IS HIGHLY DEPENDENT ON THE SERVICES OF ITS KEY EMPLOYEES.

     Omnipoint is highly dependent upon the technical and management skills of
its key employees, particularly those of Douglas G. Smith, Omnipoint's Chairman,
President and CEO. The loss of the services of any of Omnipoint's key employees
could adversely affect Omnipoint's financial condition and results of
operations. There can be no assurance that Omnipoint will be successful in
retaining its key employees, or that it will be able to attract or retain
additional skilled personnel.

     Omnipoint's rapid growth and continued expansion has placed, and may
continue to place, a significant strain on its management, as well as on its
operational and financial resources. Omnipoint's rapid growth has placed a
particular strain on its financial personnel, whose areas of responsibility have
expanded in connection with its recent financing activities and strategic
partnering negotiations. Omnipoint's ability to manage its growth effectively
will require it to continue to implement and improve its operational and
financial systems. Omnipoint's success also depends in large part on a limited
number of key technical, accounting, marketing and sales employees, as well as
on its ability to continue to attract and retain additional highly talented
personnel. Competition for qualified personnel in the industries in which it
operates is intense. These demands could require the addition of new management
personnel and the development of additional expertise by existing management.
The failure of Omnipoint's management team to effectively manage growth could
have a material adverse affect on its financial condition and results of
operations.

     OMNIPOINT HOLDS SPECIAL LICENSES THAT MAY EXPOSE IT TO ADDITIONAL RISKS.

     Omnipoint holds special qualifications under current FCC rules and
regulations which allow it to participate in special auctions of, and be
eligible for deferred payment terms and discounts for, C Block and F Block PCS
licenses. The East/West licenses to be assigned to Omnipoint in the East/West
merger also are subject to these requirements. In order to retain these licenses
and favorable government financing afforded to it as a result of these
qualifications, Omnipoint must maintain its Designated Entity status.

                                       20
<PAGE>   28

     In order to maintain all of the benefits Omnipoint has as a Designated
Entity, certain investors may not exceed certain maximum levels of stock
ownership and voting stock for a period of ten years from the date on which
Omnipoint, or in the case of East/West's licenses, East/West, acquired its C
Block and F Block licenses. While Omnipoint believes that it has taken all
necessary steps to comply with the FCC's Designated Entity requirements, it can
make no assurance that its ownership and control structure or its eligibility to
hold the East/West licenses will not be challenged. See "-- Risks related to the
VoiceStream Transactions." Assuming that the proposed VoiceStream reorganization
is completed, Omnipoint will be required to assign certain of its licenses to
joint ventures that it will not control. See "-- Risks related to the
VoiceStream reorganization" for a discussion of the effect the proposed
VoiceStream reorganization will have on Omnipoint's Designated Entity status.
East/West's PCS licenses will be among those which Omnipoint will assign to a
qualified Designated Entity. Omnipoint will be required to request and obtain
FCC approval prior to doing so. Omnipoint cannot assure you that such approval
will be obtained prior to consummation of the VoiceStream reorganization or
that, if such approval is not obtained prior to consummation of the VoiceStream
reorganization, that the FCC will not impose any penalty or that no delay will
occur.

     DELAYS IN THE BUILDOUT OF OMNIPOINT'S NETWORK FACILITIES MAY ADVERSELY
     AFFECT ITS BUSINESS.

     As a condition of license renewal, FCC rules require that Omnipoint, along
with all other C Block licensees, construct facilities with a signal level
sufficient to provide adequate service to at least one-third of the population
of its licensed service area within five years of their initial license grants
and two-thirds of the population within ten years. In addition, Omnipoint,
along, with all other 10 MHz PCS licensees, must construct facilities with a
signal level sufficient to provide adequate service to at least one-quarter of
the population in its licensed service area within five years of its initial
license grants, or make a showing of substantial service in its licensed service
area within five years of its initial license grants. Failure to meet the
coverage requirement for a particular market may subject Omnipoint to forfeiture
of its license for that market.

     Omnipoint anticipates that it will take several years to substantially
complete its targeted buildout. The buildout of the network in each market is
subject to successful completion of network design, site and facility
acquisitions, permitting, and purchase and installation of network equipment.
Delays in any of these areas may adversely affect Omnipoint's ability to
complete the buildout in a timely manner. Failure or delay in completing the
buildout of the network in the surrounding areas also may adversely affect
Omnipoint's ability to market its PCS services in the licensed areas. In
connection with the VoiceStream reorganization, Qualcomm Incorporated filed a
petition on September 16, 1999 to deny Omnipoint's application for transfer of
its New York MTA PCS license to VoiceStream Holdings. The petition claims that
Omnipoint has not satisfied the condition on its license requiring that it
construct a system that substantially uses the technology upon which its
pioneer's preference was based and that its New York MTA PCS license should be
revoked for that reason. See "-- Risks related to the VoiceStream
Transactions -- Regulatory agencies must approve the VoiceStream reorganization
and could delay or refuse to approve the VoiceStream reorganization or impose
conditions that could adversely affect VoiceStream Holdings' business or
financial condition."

RISKS RELATED TO THE VOICESTREAM TRANSACTIONS

     In addition to considering the risks described below, you should also
carefully consider the risk factors identified and described in the VoiceStream
disclosure statement, a copy of which is enclosed with this proxy
statement/prospectus.

     OMNIPOINT CANNOT ASSURE YOU THAT THE VOICESTREAM REORGANIZATION WILL BE
     CONSUMMATED.

     Completion of the VoiceStream reorganization is subject to a number of
conditions that are outside of Omnipoint's control. The failure to complete the
VoiceStream reorganization or any of the related

                                       21
<PAGE>   29

transactions expected to be completed in connection with the VoiceStream
reorganization, including the Aerial reorganization, could have a material
adverse effect on Omnipoint's business and financial condition and could
substantially impact the value of any Omnipoint securities you might receive in
the East/West merger or the VoiceStream common stock you will receive if both
the VoiceStream reorganization and the East/West merger are completed. See "The
VoiceStream Transactions -- Termination of the VoiceStream Reorganization
Agreement."

     THE VOICESTREAM REORGANIZATION AGREEMENT CONTAINS CERTAIN RESTRICTIONS ON
     OMNIPOINT'S INTERIM OPERATIONS PENDING CONSUMMATION OF THE VOICESTREAM
     REORGANIZATION.

     The VoiceStream reorganization agreement requires Omnipoint, until either
the closing of the VoiceStream reorganization or the termination of the
VoiceStream reorganization agreement, to conduct its business in the ordinary
course consistent with past practice and to use its reasonable efforts to
preserve its business organizations and relationships with third parties. In
addition, Omnipoint has agreed to some specific restrictions, subject to certain
exceptions described in the VoiceStream reorganization agreement. For example,
with certain exceptions, Omnipoint may not:

     - enter into any reorganization (Omnipoint has obtained VoiceStream's
       approval to enter into the East/West merger), liquidation or other
       significant transaction;

     - encumber or transfer any assets having a fair market value exceeding $5
       million, or $10 million in the aggregate;

     - issue or dispose of equity securities, options or other securities
       convertible or exercisable for equity securities, except in connection
       with the exercise or conversion of options or convertible securities
       outstanding on June 23, 1999;

     - incur or assume any non-vendor related indebtedness other than the
       greater of $300 million or the amount needed to finance a six-month
       rolling forecast of cash needs;

     - make any loans, advances or capital contributions;

     - make certain capital expenditures;

     - enter into any agreement that would materially limit Omnipoint's ability
       or the ability of VoiceStream or VoiceStream Holdings to engage in the
       wireless communications business or any other business.

     These limitations could restrict Omnipoint's ability to generate cash flow,
obtain sufficient capital to service its existing and future debt or fund its
future capital expenditures. As a result, Omnipoint may be unable to adapt
timely and effectively to changes in its business and industry or take advantage
of various opportunities that may arise. See "The VoiceStream
Transactions -- Omnipoint's Interim Operations."

     OMNIPOINT WILL EXPERIENCE A CHANGE OF CONTROL UPON COMPLETION OF THE
     VOICESTREAM REORGANIZATION. VOICESTREAM HOLDINGS' BUSINESS STRATEGY MAY BE
     DIFFERENT FROM OMNIPOINT'S OPERATING STRATEGY AND VOICESTREAM HOLDINGS MAY
     EXPERIENCE DIFFICULTY INTEGRATING ITS OPERATIONS WITH THOSE OF OMNIPOINT
     AND/OR AERIAL.

     Omnipoint will experience a change of control if the VoiceStream
reorganization is completed. Assuming the completion of the VoiceStream
reorganization, Omnipoint expects that the current stockholders of Omnipoint, as
well as the East/West stockholders, assuming the East/West merger is
consummated, will own a minority of the outstanding shares of VoiceStream
Holdings. In connection with the VoiceStream transactions, and assuming that
both the VoiceStream reorganization and the Aerial reorganization are completed,
the size of the VoiceStream Holdings board will be increased to 17 members and
four of the currently serving members of Omnipoint's board will be appointed to
the VoiceStream Holdings board. Omnipoint expects that the remaining seats on
the VoiceStream Holdings

                                       22
<PAGE>   30

board will be filled by currently serving members of the VoiceStream board and
others as described in the VoiceStream disclosure statement, a copy of which is
enclosed with this proxy statement/prospectus.

     Because the Omnipoint-designated directors will constitute less than a
majority of the membership of the VoiceStream Holdings board and none of
Omnipoint's executive officers, other than Mr. Smith, is currently designated to
serve as an executive officer of VoiceStream Holdings, Omnipoint's current
directors and executive officers will not be able to control the outcome of
future decisions regarding the VoiceStream Holdings' business strategy and
operations. VoiceStream's business strategy and operations are expected to
differ in a number of respects from Omnipoint's current business strategy and
operations. Omnipoint can make no assurances that any strategies pursued by
VoiceStream Holdings' board or management will not adversely affect Omnipoint's
existing business strategy or operations. Moreover, Omnipoint cannot assure you
that any attempts by VoiceStream Holdings to integrate some or all of its
operations, networks and billing and other systems with those of VoiceStream,
and Aerial if the Aerial reorganization is completed, following the VoiceStream
reorganization will be successful and will not be disruptive to the combined
company as a whole. Any disruptions stemming from the business strategy
implemented by the VoiceStream Holdings' board and management team or the
integration of the operations of Omnipoint and VoiceStream, and Aerial if the
Aerial reorganization is completed, could have a material adverse effect on
Omnipoint's and on VoiceStream Holdings' growth rates, business, financial
condition and results of operations.

     ASSUMING THAT THE VOICESTREAM REORGANIZATION IS COMPLETED, OMNIPOINT WILL
     BE REQUIRED TO TRANSFER CERTAIN OF ITS LICENSES TO JOINT VENTURES THAT IT
     WILL NOT CONTROL.

     When implementing the PCS licensing scheme in the United States, the FCC
established six PCS license Blocks, A, B, C, D, E and F, and adopted rules that
granted a narrow category of defined "Designated Entities" the right to own and
operate under the C and F Block PCS licenses. Although Omnipoint qualified as a
Designated Entity under FCC rules and is therefore able to hold and operate
under C and F Block PCS licenses, VoiceStream Holdings does not qualify as a
Designated Entity and therefore cannot own or operate under C or F Block PCS
licenses.

     As a result, immediately prior to the VoiceStream reorganization,
Omnipoint's C and F Block licenses and its existing rights to obtain pending C
Block PCS licenses will be assigned to two new joint venture entities controlled
by Cook Inlet. The East/West PCS licenses also must be assigned to a qualified
Designated Entity in order to avoid possible penalties imposed by the FCC;
Omnipoint intends to assign the East/West licenses to a joint venture entity
controlled by Cook Inlet. In the event that the VoiceStream reorganization
occurs prior to the East/West merger, Omnipoint will become a subsidiary of
VoiceStream Holdings before the East/West PCS licenses are assigned to Omnipoint
in the East/West merger, and would thus not be a Designated Entity under the
FCC's rules. In that case, Omnipoint intends to complete the assignment of the
East/West licenses to the Cook Inlet-controlled entity immediately upon
assignment of the licenses to Omnipoint. Because the East/West PCS licenses may
be held briefly by Omnipoint after it is no longer a Designated Entity, a waiver
of the FCC's rules regarding eligibility to hold these licenses may be required
as part of the FCC's consent to the assignment, and Omnipoint intends to request
such a waiver, if necessary. Omnipoint cannot assure you that the FCC will grant
such a request. Omnipoint will have a 49.9% minority interest in each of these
entities and VoiceStream Holdings is expected to provide technical services to
each of these joint venture entities. The joint venture entities will hold or
have rights to acquire licenses including those of some key urban markets. Among
the markets previously owned and operated by Omnipoint that will be acquired by
and subsequently owned and operated by these joint venture entities are
Philadelphia. Omnipoint will not have affirmative control over and will maintain
limited investor protection rights in the new joint venture entities.
VoiceStream Holdings will have substantial financial commitments and must rely
on corresponding financial commitments to the joint venture entities from Cook
Inlet in the markets served by these joint venture entities. Also, many of the
systems owned by these joint venture

                                       23
<PAGE>   31

entities have not been built out and the joint venture entities will have
substantial capital needs in connection with such buildouts. Omnipoint cannot
guarantee that these joint venture entities will be able to raise sufficient
capital, whether through bank borrowings or otherwise, to complete the buildout
of their systems. While VoiceStream Holdings will have certain rights which may
allow it to acquire interests in these joint venture entities that it does not
currently own, Omnipoint cannot assure you that third parties will not outbid
VoiceStream Holdings.

     THE FCC AND OTHER REGULATORY AGENCIES MUST APPROVE THE VOICESTREAM
     REORGANIZATION AND COULD DELAY OR REFUSE TO APPROVE THE VOICESTREAM
     REORGANIZATION OR IMPOSE CONDITIONS THAT COULD ADVERSELY AFFECT VOICESTREAM
     HOLDINGS' BUSINESS OR FINANCIAL CONDITION.

     The Communications Act and FCC rules require the FCC's prior approval of
the transfer of control of Omnipoint's PCS licenses to VoiceStream Holdings, as
well as the assignment of Omnipoint's C and F Block PCS licenses to the two new
joint venture entities controlled by Cook Inlet. Omnipoint and VoiceStream filed
applications to make these transfers and assignments on July 15, 1999. On August
16, 1999, the FCC released a Public Notice announcing the acceptance for filing
of the applications. On September 10, 1999, National Telecom PCS, Inc. filed a
petition to deny Omnipoint's assignment to Cook Inlet of eleven licenses on
which Omnipoint was the high bidder in the FCC's recently completed C Block
reauction (the FCC Auction 22). Those licenses were formerly held by a company
now in Chapter 11 bankruptcy reorganization against whom NatTel has filed an
antitrust claim. NatTel argues that the FCC should not permit the assignment of
the licenses until the antitrust claim is resolved. On September 16, 1999,
Qualcomm Incorporated filed a petition to deny Omnipoint's application for
transfer of its New York MTA PCS license to VoiceStream Holdings. The petition
claims that Omnipoint has not satisfied the condition on its license requiring
that it construct a system that substantially uses the technology upon which its
pioneer's preference was based and that Omnipoint's New York MTA PCS license
should be revoked for that reason. The full cycle of such comment and reply
concluded on October 5, 1999. While Omnipoint expects that the applications will
be processed in accordance with the FCC's routine procedures and without
conditions other than conditions that are consistent with those generally
applicable to the transfer and assignment of PCS licenses, there can be no
assurance that the FCC will grant the applications, that the FCC will grant the
applications without conditions, or that there will be no delay caused by the
filing of a challenge to the transfer and assignment applications.

RISKS RELATED TO THE WIRELESS COMMUNICATIONS AND TECHNOLOGY INDUSTRIES

     OMNIPOINT FACES INTENSE COMPETITION FROM OTHER WIRELESS SERVICE PROVIDERS,
     WHICH COULD ADVERSELY AFFECT ITS ABILITY TO GROW ITS SUBSCRIBER BASE AND
     REVENUES.

     Omnipoint competes with providers of PCS, cellular and other wireless
services. Under the current rules of the FCC, up to six PCS licenses and two
cellular licenses may be issued in each geographic area. In addition, Nextel
operates on ESMR frequencies. Due to license aggregation, currently the number
of PCS competitors, cellular competitors and Nextel ranges from five to seven
across the top 50 markets. Thus, competition is intense. Omnipoint competes
against AT&T Wireless, Bell Atlantic Mobile Systems, Nextel, SBC Communications,
Sprint PCS and Vodafone AirTouch, among others. Many of these competitors have
substantially greater financial, technical, marketing, sales and distribution
resources than it does, and several operate in multiple segments of the
industry. AT&T Wireless, Nextel and Sprint PCS operate substantially nationwide
networks, and Bell Atlantic Mobile Systems and Vodafone AirTouch, among others,
through joint ventures and affiliation arrangements, could operate substantially
nationwide wireless systems throughout the continental United States. In short,
there can be no assurance that Omnipoint will be able to successfully attract
and retain customers and grow its subscriber base and revenues.

     Competition in the communications equipment industry is also intense. The
industry consists primarily of major domestic and international companies which
have financial, technical, marketing,

                                       24
<PAGE>   32

sales, manufacturing, distribution and other resources substantially greater
than Omnipoint does. In the cellular, PCS and wireless local loop markets,
Omnipoint competes against analog and various digital technologies, the most
prominent of which are either TDMA-based or CDMA-based systems. In addition, a
number of privately and publicly held telecommunications companies, including
Northern Telecom and Ericsson, are developing digital telecommunications systems
and products and implementing competing digital wireless technologies. It is
possible that Omnipoint's competitors will devote significantly greater
financial, technical, marketing and other resources to aggressively market
competitive communications systems, or develop and adopt competitive digital
cellular technologies. Any such efforts by Omnipoint's competitors may
materially adversely affect its financial condition, results of operations and
cash flows in the future.

     OMNIPOINT IS SUBJECT TO EXTENSIVE GOVERNMENT REGULATION, ANY CHANGE IN
     WHICH COULD AFFECT ITS BUILD OUT PLAN OR ITS FINANCIAL PERFORMANCE.

     The licensing, construction, operation, sale and interconnection
arrangements of wireless telecommunications systems are regulated to varying
degrees by the FCC and, depending on the jurisdiction, also may be regulated by
state and local governmental bodies. There can be no assurance that either the
FCC or such state and local agencies will not adopt regulations or take other
actions that would adversely affect Omnipoint's business. Omnipoint cannot
assure you that it will be able to obtain and retain all necessary governmental
authorizations and permits. Failure to do so could negatively affect Omnipoint's
existing operations, and could delay or prevent proposed operations. Omnipoint
may be required to modify its business plans or operations as new regulations
arise. Omnipoint cannot assure you that it will be able to do so in a
cost-effective manner, or at all.

     THERE IS A RISK THAT OMNIPOINT COULD LOSE THE NEW YORK MTA LICENSE OR OTHER
     LICENSES AS A RESULT OF COURT OR REGULATORY PROCEEDINGS.

     Omnipoint's New York MTA A Block license was issued as a Pioneer's
Preference, and as a consequence contains a condition that requires it to
construct a PCS system that "substantially uses" the design and technology upon
which its Pioneer's Preference license was based. The FCC has never specifically
defined the phrase "substantial use." Although there can be no assurance as to
whether or how the FCC will in the future construe the phrase "substantial use,"
Omnipoint believes, on the basis of prior FCC pronouncements, that its build out
plan in connection with the New York MTA has satisfied the "substantial use"
condition and has so notified the FCC. None of Omnipoint's other licenses
contain a similar condition. If Omnipoint loses the New York MTA A Block 30 MHz
license, it would only hold the New York BTA D Block 10 MHz license and would be
required to make significant capital expenditures to be able to continue to
operate in the New York City BTA, Omnipoint's largest market, and it would cease
to have licenses in certain BTAs in the New York MTA.

     In addition, FCC licenses to provide PCS services are subject to renewal
requirements and to revocation at any time for cause. Omnipoint's New York MTA A
Block license will expire in December 2004 and its other licenses will expire
beginning in 2006. There can be no assurance that the FCC will renew them.

     CONCERNS ABOUT HEALTH AND SAFETY RISKS ASSOCIATED WITH WIRELESS HANDSETS
     AND THE POSSIBILITY OF RELATED LEGISLATION MAY AFFECT OMNIPOINT'S
     PROSPECTS.

     Media reports have suggested that some radio frequency emissions from
wireless handsets may raise various health concerns, including cancer, and may
interfere with various electronic medical devices, including hearing aids and
pacemakers. Concerns over radio frequency emissions may discourage the use of
wireless handsets, which would adversely affect Omnipoint's business.

     The first phase of a university study funded by the wireless industry found
that digital technologies cause interference with hearing aids in some
instances. In addition, an industry group has announced

                                       25
<PAGE>   33

that it is gathering information on possible interference by PCS standards with
medical devices. The findings of studies like these could have an adverse effect
on the wireless industry, on Omnipoint's business, or on the use of GSM
technology. Such findings could lead to the adoption of governmental regulations
that could have an adverse effect on Omnipoint's business.

     Several states have proposed or enacted legislation that would limit or
prohibit the use or possession of mobile phones while driving an automobile. If
states adopt and strictly enforce such legislation, this legislation could have
an adverse effect on Omnipoint's business.

     OMNIPOINT'S OPERATIONS MAY BE HARMED IF ITS, OR ITS VENDORS' COMPUTER
     PROGRAMS DO NOT FUNCTION PROPERLY BEFORE, DURING AND AFTER THE YEAR 2000.


     Omnipoint is in the process of modifying portions of its software so that
it will function properly during and after the year 2000. Any of Omnipoint's
computer programs, or those of its vendors, that have date-sensitive software or
embedded technology may recognize a date containing "00" as the year 1900 rather
than the year 2000. Omnipoint is currently remediating its critical systems to
address the year 2000 issue. Critical systems are those whose failure poses a
risk of disruption to the ability to provide wireless services, to collect
revenues, to meet safety standards, or to comply with legal requirements.
Omnipoint expects that it will incur ongoing internal staff costs as well as
consulting and other expenses related to infrastructure and facilities
enhancements necessary to prepare its systems for the year 2000. There can be no
assurance that the remediation of these critical systems has been completed.



     Omnipoint purchases much of its technology, including technology associated
with its critical systems, from third parties. Omnipoint depends on those third
parties to assess the impact of the year 2000 issue on the technology and the
services they supply and to take any necessary corrective action. Omnipoint
cannot assure you that these third parties have taken the necessary corrective
action. If these parties did not take the necessary corrective action, it may
have an adverse effect on Omnipoint's business.

                              THE EAST/WEST MERGER

BACKGROUND OF THE EAST/WEST MERGER

     During the past few years, Omnipoint reviewed developing trends in the
telecommunications industry and a variety of strategic alternatives, including
acquisitions to extend the geographic scope of its business operations. In
connection with such review, from time to time during 1998, Douglas Smith,
Omnipoint's Chairman and CEO, spoke with representatives of East/West concerning
possible transactions relating to the PCS licenses held by East/West.

     In 1998, representatives of Omnipoint and East/West met in New York to
discuss the wireless industry and possible transactions between Omnipoint and
East/West involving East/West's PCS licenses.

     In February 1999, discussions between Omnipoint and representatives of
East/West relating to the PCS licenses held by East/West were suspended due to
the FCC C Block reauction. The FCC reauction ended on May 6, 1999.

     In May 1999, East/West entered into a non-exclusive agreement with Gabelli
and Company, Inc. with the purpose of locating a possible partner/buyer of
East/West's PCS licenses.

     On May 11, 1999, Mr. Smith spoke with a representative of East/West, and
between May 12, 1999 and June 10, 1999, Mr. Smith had several conversations with
representatives of East/West relating to a proposed transaction to acquire
East/West or East/West's PCS licenses.

     On June 23, 1999, Omnipoint signed definitive agreements with respect to
the VoiceStream reorganization.

     From June 30, 1999 through August 19, 1999, Mr. Smith discussed various
proposals with representatives of VoiceStream. During such period, Omnipoint and
VoiceStream held several discussions with East/West concerning the terms of a
potential business combination transaction between Omnipoint and East/West.

     On August 27, 1999, Omnipoint sent a draft term sheet to East/West
describing a possible transaction involving the purchase of East/West and an
initial investment in East/West by Omnipoint as well as other terms.

     From August 27, 1999 until September 20, 1999, representatives of East/West
and Omnipoint had numerous telephone conversations in connection with the draft
term sheet. During this period, Omnipoint conducted due diligence of East/West
and East/West conducted due diligence on Omnipoint's business and financial
condition. On September 23, 1999, Omnipoint and its outside legal counsel for
the transaction and East/West and its outside legal counsel for the transaction
commenced drafting and negotiating the terms of a proposed merger agreement.

     From late September 1999 through the signing on October 22, 1999, numerous
meetings and telephone conversations took place among representatives of
East/West and Omnipoint in connection with various structural issues, including
tax and regulatory issues. During such time, the parties continued their due
diligence reviews and negotiations and exchanged additional information. The
parties also held numerous discussions in connection with the preparation,
negotiation and finalization of the East/West merger agreement and other related
documents, including the voting agreement, the securities purchase agreement and
the supplemental agreement.

     During the course of the discussions between Omnipoint and East/West,
members of the East/West board of directors held several meetings concerning the
terms of the East/West merger and the terms and conditions of the East/West
merger agreement, the East/West/Omnipoint Securities Purchase Agreement and the
other related documents and consulted with its outside legal advisors concerning
the terms and conditions of the East/West merger. On October 20, 1999, the board
of directors of East/West

                                       27
<PAGE>   35

unanimously approved the East/West merger agreement and the related transactions
and determined to recommend that the stockholders vote in favor of approval and
adoption of the East/West merger agreement.

     On October 21, 1999, Omnipoint held a meeting of its board by phone to
consider and vote upon the proposed East/West merger agreement and related
transactions. The board reviewed the strategic rationale for, and had a lengthy
discussion concerning, the proposed transaction. Following such discussions, the
Omnipoint board approved the execution of such documents and related matters.

     Following approval of the East/West merger agreement and related documents
by the board of directors of each party, the East/West merger agreement, the
voting agreement, the side agreement and the securities purchase agreement were
finalized and executed by each of the parties. The terms of the East/West merger
were announced in a joint press release that was issued before the opening of
the stock markets on October 22, 1999.

OMNIPOINT'S REASONS FOR THE EAST/WEST MERGER

     The Omnipoint board has determined that the East/West merger agreement and
the East/West merger are fair to and in the best interests of Omnipoint's
stockholders, has approved the East/West merger agreement, and adoption of the
transactions contemplated by, the East/West merger agreement.

     The Omnipoint board believes that the completion of the East/West merger
will substantially benefit both Omnipoint and its stockholders. In reaching its
decision to approve the East/West merger agreement, the Omnipoint board
consulted with Omnipoint's legal advisors and senior management and considered
numerous factors, including:

     - the Omnipoint board's review of and familiarity with the business,
       assets, competitive position, and prospects of Omnipoint;

     - the strategic and financial alternatives available to Omnipoint in the
       highly competitive wireless communications industry, as well as the
       attractiveness of a business combination with East/West and the strategic
       fit between Omnipoint and East/West;

     - benefits expected to be achieved as a result of combining Omnipoint and
       East/West;

     The foregoing summary addresses the material facts, matters and information
considered by the Omnipoint board in connection with its deliberations on the
combination of Omnipoint and East/West. In view of the variety of factors
considered, the Omnipoint board did not find it practical to and did not make a
specific assessment of or otherwise assign relative weights to the specific
facts, matters and information considered. The Omnipoint board adopted the
East/West merger agreement and approved the transactions contemplated thereby in
consideration of all of the facts, matters and information brought to its
attention.

     Taking into account all of the material facts, matters and information,
including those described above, the Omnipoint board believes that the terms of
the East/West merger agreement and the transactions provided for therein are
fair to and in the best interest of Omnipoint's stockholders.

RECOMMENDATION OF THE BOARD OF DIRECTORS OF EAST/WEST; EAST/WEST'S REASONS FOR
THE EAST/WEST MERGER

     The East/West board believes that the terms of the East/West merger are
fair to and in the best interests of East/West and its stockholders.
Accordingly, the East/West board has unanimously approved the East/West merger
agreement and the transactions contemplated thereby and recommends approval of
the East/West merger agreement by the stockholders of East/West.

                                       28
<PAGE>   36

     In the course of its deliberations, the East/West board considered the
factors listed below in reaching its decision to approve the East/West merger
agreement and to recommend that East/West's stockholders vote to approve the
East/West merger agreement.

     - The East/West board considered the opportunity of the holders of
       East/West common stock to participate in the potential growth of the
       combined company after the merger as a result of their ownership of
       Omnipoint common stock or VoiceStream Holdings common stock, as the case
       may be.

     - The East/West board considered the historical trading price of the
       East/West common stock, the Omnipoint common stock, the VoiceStream
       common stock, and the consideration to be received by the holders of
       East/West common stock in the East/West merger.


     - The East/West board considered the fact that, as of October 20, 1999, the
       day the East/West board approved the East/West merger, (i) the value of
       the consideration to be received in respect of each share of East/West
       common stock in the merger represented an approximate 141% premium over
       the closing price per share of East/West common stock (assuming
       consummation of the East/West merger immediately prior to the
       consummation of the VoiceStream reorganization or consummation of the
       East/West merger prior to the VoiceStream reorganization) and (ii) the
       value of the consideration to be received in respect of each share of
       East/West common stock in the East/West merger represented an approximate
       122% premium over the closing price per share of East/West common stock
       (assuming that the East/West merger is consummated but the VoiceStream
       reorganization is not consummated).



     - The East/West board considered the fact that Aer Force Communications,
       Inc., the holder of East/West common stock representing 81.6% of the
       total voting power of all outstanding shares of East/West common stock
       entitled to vote at the East/West special meeting, was willing to agree
       to vote its shares of East/West common stock in favor of approval of the
       East/West merger agreement.


     - The East/West board considered the strength of both Omnipoint and
       VoiceStream in the wireless communications markets and the ability of the
       combined company to construct facilities for sale and delivery of PCS
       services and to compete in markets for wireless telecommunications
       services and products.

     - The East/West board considered the principal terms and conditions of the
       East/West merger agreement and related agreements, including the
       representations, warranties, and covenants and the conditions to each
       party's obligation to complete the East/West merger.

     - The East/West board assessed the possibility of being part of a combined
       company and the risk of continuing to be an independent company, in view
       of the increased consolidation and increased competitive trends in the
       telecommunications industry.

     - The East/West board considered the ability of Omnipoint and East/West to
       complete the East/ West merger, including their ability to obtain
       necessary regulatory approvals and their obligations to attempt to obtain
       those approvals, and determined that there was a strong likelihood that
       the East/West merger would be completed.

     - The East/West board considered the risk that the East/West merger would
       not be completed or that the VoiceStream reorganization would not be
       completed. In evaluating this risk, the East/ West board considered the
       limited circumstances under which Omnipoint could terminate the East/West
       merger agreement.

     The foregoing discussions of the information and factors considered by the
East/West board is not intended to be exhaustive but is believed to include all
material factors considered by the East/West board. In view of the wide variety
of information and factors considered, the East/West board did not
                                       29
<PAGE>   37

find it practical to, and did not, assign any relative or specific weights to
the foregoing factors, and individual directors may have given differing weights
to different factors. The East/West board did not attempt to analyze the
fairness of the conversion ratio in isolation from the considerations as to the
business of East/West and Omnipoint, the strategic merits of the East/West
merger, or the other considerations referred to above.

TREATMENT OF EAST/WEST PREFERRED STOCK

     The East/West merger agreement provides that each share of East/West
preferred stock issued and outstanding immediately prior to the effective time
of the East/West merger will be converted into and represent the right to
receive cash in the amount of $1,000 plus accrued and unpaid dividends. As of
the effective time of the East/West merger, all such shares of East/West
preferred stock shall no longer be outstanding and shall automatically be
canceled and retired and shall cease to exist.

TIMING OF CLOSING


     Unless East/West and Omnipoint agree to a different date, the closing of
the East/West merger will occur: (i) in the event that the VoiceStream
reorganization agreement has been terminated prior to the satisfaction of the
closing conditions in the East/West merger agreement, on the fifth business day
following the day on which the last of the closing conditions set forth in the
East/West merger agreement has been satisfied or waived; and (ii) in the event
that the closing conditions in the East/West merger agreement have been
satisfied or waived prior to the termination of the VoiceStream reorganization
agreement, the date that is the earliest of: (A) the date of the closing of the
VoiceStream reorganization or, if the conditions to the East/West merger are not
then satisfied or waived, the first date after the closing of the VoiceStream
reorganization on which such conditions are satisfied or waived; and (B) the
fifth business day after the first date following the date that the VoiceStream
reorganization agreement has been terminated. Upon closing of the East/West
merger, the parties will file the required certificate of merger with the
Secretary of State of Delaware, at which time the East/West merger will be
effective.


ACCOUNTING TREATMENT

     The East/West merger will be accounted for using the purchase method of
accounting with Omnipoint becoming the successor company to East/West. Under the
purchase method of accounting, the purchase price will be allocated among the
East/West assets and liabilities. The excess of purchase price over the fair
value of the identifiable tangible assets and liabilities acquired will be
recorded as intangible assets and amortized on a straight-line basis over a
period not to exceed 40 years.

TRANSACTION COSTS

     Anticipated non-recurring charges to Omnipoint as a result of the East/West
merger are estimated to be approximately $850,000. This includes transaction
costs to be paid by East/West of approximately $450,000 related to legal,
accounting and other transaction fees which will be expensed as incurred by
East/West. This total also includes non-recurring costs to be paid by Omnipoint
of approximately $400,000 related to legal, accounting and other transaction
fees, which will be considered as part of the purchase price.

INTERESTS OF EXECUTIVE OFFICERS AND DIRECTORS OF EAST/WEST IN THE EAST/WEST
MERGER

     You should be aware of the interests that executive officers and directors
of East/West have in the East/West merger. These interests are different from
and in addition to your and their interests as stockholders. In discussing the
fairness of the East/West merger to the stockholders of East/West, the East/West
board took into account these interests. These interests are summarized below.

                                       30
<PAGE>   38


     Ownership and Voting Stock.  As of the record date for the East/West
special meeting, directors and executive officers of East/West and their
affiliates beneficially owned approximately 58.1% of the outstanding shares of
East/West common stock representing approximately 85.6% of the voting power of
the East/West common stock entitled to vote at the East/West special meeting. In
addition, Aer Force, the sole East/West Class B common stockholder and
beneficial owner of 46.9% of the outstanding shares of East/West common stock,
representing approximately 81.6% of the voting power of the East/West common
stock entitled to vote at the East/West special meeting entered into a voting
agreement, dated as of October 22, 1999 with Omnipoint and East/West. In the
voting agreement, Aer Force agreed to vote all of its East/West Class B common
stock in favor of adoption and approval of the East/West merger. Victoria G.
Kane, a director of East/West, is the sole stockholder of Aer Force.


     Preferred Stock.  All of the issued and outstanding preferred stock of
East/West is owned by Lynch Corporation, a Delaware corporation. Mario J.
Gabelli, a director of East/West, serves as Chairman and Chief Executive Officer
of Lynch Corporation and is the beneficial owner of approximately 22.8% of the
outstanding common stock of Lynch Corporation.


     Fees to Gabelli and Company, Inc.  Gabelli and Company, Inc. has provided
certain services to East/West in connection with the transactions contemplated
by the Securities Purchase Agreement and the East/West merger agreement. In
return for these services, if the East/West merger and the VoiceStream
reorganization both are completed, Gabelli and Company, Inc. is entitled to
receive 20,625 shares of VoiceStream Holdings common stock and cash equal to
$200,000. If, on the other hand, the East/West merger is completed and the
VoiceStream reorganization agreement has been terminated, then Gabelli and
Company, Inc. will receive 25,000 shares of Omnipoint common stock. If the
East/West merger is not completed, Gabelli and Company, Inc. is entitled to
receive only a fee of $150,000 in cash from East/West for services performed in
connection with the transactions contemplated by the securities purchase
agreement. The majority of Gabelli and Company, Inc.'s outstanding securities is
beneficially owned by Mario J. Gabelli, a director of East/West.


     Indemnification.  Pursuant to the East/West merger agreement, Omnipoint
has, for the time periods specified in the East/West merger agreement, agreed to
indemnify each present and former director and officer of East/West against
liabilities or expenses incurred in connection with claims arising out of or
pertaining to matters existing or occurring at or prior to the effective time of
the East/West merger to the fullest extent permitted under Delaware law.

REGULATORY APPROVALS


     Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended
(the "HSR Act"), and the regulations thereunder, Omnipoint and East/West may not
merge unless Notification and Report Forms have been filed with the Antitrust
Division of the United States Department of Justice (the "Antitrust Division")
and the United States Federal Trade Commission (the "FTC"), and the waiting
period requirements have expired or are otherwise earlier terminated by the
Antitrust Division and the FTC. On November 5, Omnipoint and East/West submitted
the required filings to the Antitrust Division and the FTC, and on December 8,
1999 received notification that the waiting period under the HSR Act has been
terminated.


     The Communications Act and FCC rules require the FCC's prior approval of
the assignment of East/West's PCS licenses to Omnipoint. Omnipoint and East/West
filed an application for approval of the assignment of East/West's licenses to
Omnipoint on November 1, 1999. While we expect that the application will be
processed in accordance with the FCC's routine procedures and without conditions
other than conditions that are consistent with those generally applicable to the
transfer and assignment of PCS licenses, we cannot assure you that the FCC will
grant the application, that the FCC will grant the application without
conditions, or that there will be no delay caused by the filing of a challenge
to the transfer and assignment application. A condition to Omnipoint's
obligation to close the East/West

                                       31
<PAGE>   39

merger is the grant of the requisite FCC consent becoming final. A "final" FCC
order is one that has not been stayed and is no longer subject to review by the
FCC or the courts because the statutory period for seeking such review has
expired without any request for review or stay pending. Following the FCC's
grant of consent to the East/West merger, we cannot assure you that there will
not be any post-grant challenges by private parties or actions by the FCC or the
courts that would delay or prevent finality. Though Omnipoint may waive finality
as a condition of closing, we cannot assure you that it will do so.

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF THE EAST/WEST MERGER

     In the opinion of Latham & Watkins, counsel to East/West, the material
United States federal income tax considerations generally applicable to United
States holders of (i) East/West common stock who, pursuant to the East/West
merger, exchange their East/West common stock for either Omnipoint common stock,
Omnipoint Series E preferred stock or VoiceStream Holdings common stock, as the
case may be, and (ii) holders of East/West preferred stock whose stock is
acquired pursuant to the East/West merger for cash are described below. Except
as described below, East/West's obligation to consummate the East/West merger is
conditioned upon East/West's receipt of an opinion from Latham & Watkins to the
effect that the East/West merger will be treated for federal income tax purposes
as a reorganization described in Section 368(a) of the Internal Revenue Code. In
addition, except as described below, Omnipoint's obligation to consummate the
East/West merger is conditioned upon Omnipoint's receipt of an opinion from
Piper Marbury Rudnick & Wolfe LLP to the effect that:

     - the East/West merger will be treated for federal income tax purposes as a
       reorganization described in Section 368(a) of the Internal Revenue Code,
       and

     - the East/West merger will not result in recognition of gain by Omnipoint
       or East/West, except for (i) gain, if any, resulting from the purchase by
       Omnipoint of shares of East/West and (ii) gain, if any, resulting from
       the payment of a broker fee in stock of Omnipoint.

     Notwithstanding the foregoing, East/West is obligated to consummate the
East/West merger if Latham & Watkins does not deliver its opinion, and Omnipoint
is obligated to consummate the East/ West merger if Piper Marbury Rudnick &
Wolfe LLP does not deliver its opinion, if the opinions are not delivered
because of the failure, or possible failure, of the East/West merger to satisfy
the continuity of interest requirement of Treasury Regulation Section 1.368-1(e)
as a result of a change, or possible change, in the price of Omnipoint Series E
preferred stock, Omnipoint common stock, VoiceStream common stock or VoiceStream
Holding common stock between the date the East/West merger agreement was
executed and the date the East/West merger is consummated. The continuity of
interest requirement of Treasury Regulation Section 1.368-1(e) generally
requires that a substantial part of the proprietary interests of East/West
shareholders be preserved in the form of proprietary interests in Omnipoint
after the East/West merger. Whether the continuity of interest requirement is
satisfied will depend, in part, on the amount of cash received by the East/West
shareholders, including the holders of East/West's preferred stock, in
connection with the East/West merger relative to the fair market value of the
stock received by the East/West common stockholders in the East/West merger.

     The minimum value of stock necessary to satisfy the continuity of interest
requirement is not entirely clear. It is likely that Latham & Watkins and Piper
Marbury Rudnick & Wolfe LLP will each be unable to render a legal opinion that
the East/West merger qualifies as a reorganization unless the value of the stock
to be received by holders of East/West stock is at least 45% of the aggregate
value of the consideration (both stock and cash) received by such holders.
However, it is possible that, even in the absence of a legal opinion, the
continuity of interest requirement could be satisfied with a somewhat lower
percentage of stock, and holders of East/West common stock are urged to consult
their own tax advisors on this point. Since the fair market value of the stock
to be issued to holders of East/West

                                       32
<PAGE>   40

common stock in the East/West merger will not be known until the date the
East/West merger is consummated, it is not currently possible to determine if
the East/West merger will qualify as a reorganization within the meaning of
Section 368(a) of the Internal Revenue Code. As a result of the provision in the
East/West merger agreement which requires East/West and Omnipoint to consummate
the East/West merger if the opinions of Latham & Watkins and Piper Marbury
Rudnick & Wolfe LLP are not delivered due to failure to satisfy the continuity
of interest requirement, it is possible that the East/West merger will be
consummated even if the East/West merger does not qualify as a reorganization
under Section 368(a) of the Internal Revenue Code. If the East/West merger does
not qualify as a tax-free reorganization, then the holders of East/West common
stock who participate in the East/West merger will be participating in a fully
taxable transaction.

     Under certain circumstances, Omnipoint, VoiceStream and VoiceStream
Holdings have the right, without causing Omnipoint to be in breach of the
East/West merger agreement, to take certain actions which would otherwise result
in a violation of the East/West merger agreement, and which might result in the
failure of the East/West merger to qualify as a tax-free reorganization. See
"The East/West Merger -- Certain Rights of Omnipoint, VoiceStream and
VoiceStream Holdings Under the East/West Merger Agreement." If this were to
occur, the opinions referred to above could not be delivered, and neither
East/West nor Omnipoint would be required to consummate the East/West merger.
The following discussion assumes that the East/West merger will in fact be
consummated according to the terms of the East/West merger agreement, without
any actions being taken under this provision.

     This discussion is, and the opinion of Latham & Watkins will be, if issued,
based upon current provisions of the Internal Revenue Code, current applicable
U.S. Treasury regulations promulgated thereunder, and judicial and
administrative decisions and rulings. The opinion of Latham & Watkins will be
based on the facts, representations and assumptions set forth or referred to in
such opinion, including representations contained in certificates executed by
officers of East/West, Omnipoint, VoiceStream and VoiceStream Holdings. This
discussion is not binding on the Internal Revenue Service or the courts, and
there can be no assurance that the Internal Revenue Service or the courts will
not take a contrary view. No ruling from the Internal Revenue Service has been
or will be sought. Future legislative, judicial or administrative changes or
interpretations could alter or modify the statements and conclusions set forth
herein, and any changes or interpretations could be retroactive and could affect
the tax consequences to the stockholders of East/West.

     The discussion below and the opinion of Latham & Watkins, assuming this
opinion is issued, do not purport to deal with all aspects of federal income
taxation that may affect particular stockholders in light of their individual
circumstances, and are not intended for stockholders subject to special
treatment under the federal income tax law. Stockholders subject to special
treatment include:

     - insurance companies,

     - tax-exempt organizations,

     - financial institutions,

     - broker-dealers,

     - foreign persons,

     - stockholders who hold their stock as part of a hedge, appreciated
       financial position, straddle or conversion transaction,

     - stockholders who do not hold their stock as capital assets and

     - stockholders who have acquired their stock upon the exercise of employee
       options or otherwise as compensation.

                                       33
<PAGE>   41

In addition, the discussion below does not, and the opinion of Latham & Watkins,
assuming this opinion is issued, will not, consider the effect of any applicable
state, local or foreign tax laws.

EACH HOLDER OF EAST/WEST COMMON STOCK AND EAST/WEST PREFERRED STOCK IS URGED TO
CONSULT HIS, HER OR ITS TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES TO
HIM, HER OR IT OF THE TRANSACTION DESCRIBED HEREIN, INCLUDING THE APPLICABILITY
AND EFFECT OF ANY STATE, LOCAL OR FOREIGN TAX LAWS, AND OF CHANGES IN APPLICABLE
TAX LAWS.

TAX CONSEQUENCES TO HOLDERS OF EAST/WEST COMMON STOCK.

     TAX CONSEQUENCES OF THE EAST/WEST MERGER IF THE VOICESTREAM REORGANIZATION
     OCCURS IMMEDIATELY AFTER THE EAST/WEST MERGER

     As described in more detail under the heading "The East/West Merger
Agreement -- Conversion of East/West Common Stock" the parties presently
anticipate, but cannot assure you, that the VoiceStream reorganization will
occur immediately after the completion of the East/West merger. Assuming this is
the case, automatically upon completion of the VoiceStream reorganization, each
share of Omnipoint Series E preferred stock issued to holders of East/West
common stock in the East/West merger will become exchangeable for the standard
election consideration multiplied by the conversion ratio. The standard election
consideration consists of shares of VoiceStream Holding common stock and cash.

     Tax-Free Merger

     Assuming the continuity of interest requirement of Treasury Regulation
Section 1.368-1(e) is satisfied and the accuracy of the representations and
assumptions referred to above in the first six paragraphs of this section upon
which the opinion of Latham & Watkins will be based, the East/West merger will
constitute a reorganization within the meaning of Section 368(a) of the Internal
Revenue Code.

     It is not clear whether the receipt of Omnipoint Series E preferred stock
by the holders of East/ West common stock in the East/West merger will be
ignored for federal income tax purposes and the transaction treated as though
holders of East/West common stock exchanged such stock for their pro rata share
of the standard election consideration. As described in more detail below under
the headings "-- Tax Free Merger; Deemed Issuance Of The Standard Election
Consideration For East/West Common Stock" and "Tax Free Merger; Issuance of
Omnipoint Series E Preferred Stock For East/West Common Stock", whether or not
the transaction is so treated, the holders of East/West common stock will not
recognize any gain in the East/West merger, except to the extent of cash
received, or deemed received, by the holders of East/West common stock.

     Tax-Free Merger; Deemed Issuance of The Standard Election Consideration for
     East/West Common Stock

     If the VoiceStream reorganization occurs immediately after the East/West
merger, and the momentary receipt of the Omnipoint Series E preferred stock is
ignored for federal income tax purposes, then each holder of East/West common
stock will be treated for federal income tax purposes as if it received its pro
rata share of the standard election consideration in exchange for its shares of
East/West common stock. In this case, a holder of East/West common stock will
recognize gain in the East/West merger in an amount equal to the lesser of (i)
the cash deemed received in the East/West merger and (ii) the difference between
the fair market value of the standard election consideration received in the
East/West merger and the adjusted tax basis in the shares of East/West common
stock exchanged therefor. Except to the extent of gain recognized as a result of
the deemed receipt of cash in lieu of a fractional share of VoiceStream Holdings
common stock, the gain recognized will be taxed as a dividend, to the extent of
each holder's ratable share of East/West's accumulated earnings and profits, if

                                       34
<PAGE>   42

the receipt of the cash has "the effect of the distribution of a dividend." Any
gain recognized in excess of a holder's ratable share of East/West's accumulated
earnings and profits will be capital gain.

     To determine if the receipt of cash in the East/West merger has "the effect
of the distribution of a dividend," a holder of East/West common stock will be
treated as if it solely received stock of VoiceStream Holdings in the East/West
merger and then exchanged the extra shares of VoiceStream Holdings common stock
for the cash deemed received in the East/West merger. The receipt of cash will
be treated as having "the effect of the distribution of a dividend" unless the
deemed redemption of VoiceStream Holdings common stock for cash is (i)
"substantially disproportionate" or (ii) is "not essentially equivalent to a
dividend"; each within the meaning of Section 302(b) of the Internal Revenue
Code. A deemed redemption is not essentially equivalent to a dividend if it
results in a "meaningful reduction" in the holders' interest in VoiceStream
Holdings. If as a result of the deemed redemption of the VoiceStream Holdings
common stock, a stockholder whose relative stock interest in VoiceStream
Holdings is minimal and who exercises no control over VoiceStream Holdings has a
reduction in its proportionate interest in VoiceStream Holdings, taking into
account the constructive ownership rules of Section 318 of the Internal Revenue
Code, that stockholder should be regarded as having experienced a meaningful
reduction in its interest in VoiceStream Holdings common stock. There can be no
certainty, however, as to whether a "meaningful reduction" has occurred because
the applicable test is not based on numerical criteria. Satisfaction of the
"substantially disproportionate" test is dependent upon compliance with the
objective tests set forth in section 302(b)(2) of the Internal Revenue Code.
Each holder should consult its own tax advisor as to its ability, in light of
its own particular circumstances, to satisfy the foregoing tests. Additionally,
corporate holders should consult their own tax advisors concerning the
availability of the corporate dividends received deduction and the possible
application of the extraordinary dividend rules of Section 1059 of the Internal
Revenue Code to an exchange by a corporate holder for whom the distribution is
taxable as a dividend.

     A holder of East/West common stock who is deemed to receive cash in lieu of
a fractional share of VoiceStream Holdings' common stock in the East/West merger
will be treated as having received the fractional share pursuant to the
East/West merger and then as having exchanged the fractional share for cash in a
redemption by VoiceStream Holdings. Any gain or loss attributable to fractional
shares will be capital gain or loss. The amount of this gain or loss will be
equal to the difference between the portion of the holder's tax basis in the
East/West common stock surrendered in the East/West merger that is allocated to
the fractional share and the cash payment received in lieu thereof. Any gain or
loss will be long-term capital gain or loss if the East/West common stock that
is deemed to be redeemed is considered to have been held for more than one year
at the effective time of the East/West merger.

     The tax basis of the VoiceStream Holdings common stock deemed received by a
holder of East/West common stock in the East/West merger generally will be equal
to the tax basis of the East/West common stock surrendered in the East/West
merger (excluding any portion of the holder's tax basis allocated to fractional
shares of VoiceStream Holdings common stock), decreased by the amount of cash
deemed received in the East/West merger (other than cash received in lieu of
fractional shares of VoiceStream Holdings common stock) and increased by the
amount of gain recognized in the East/West merger (other than gain recognized as
a result of the receipt of cash in lieu of fractional shares of VoiceStream
Holdings common stock).

     The holding period of the VoiceStream Holdings common stock deemed received
by each East/West common stockholder in the East/West merger will include the
holding period for the East/West common stock surrendered in exchange therefor.

     Tax-Free Merger; Issuance of Omnipoint Series E Preferred Stock for
     East/West Common Stock

     If the form of the East/West merger is respected for federal income tax
purposes each holder of East/West common stock will be treated as if it received
Omnipoint Series E preferred stock, instead of

                                       35
<PAGE>   43

its pro rata share of the standard election consideration, in exchange for its
shares of East/West common stock. In this case, no gain or loss will be
recognized by the holders of East/West common stock upon the receipt of
Omnipoint Series E preferred stock in the East/West merger. As described below,
holders of East/West common stock will recognize gain upon the receipt of their
pro rata share of the standard election consideration in exchange for the
Omnipoint Series E preferred stock.

     A condition to the VoiceStream reorganization is Omnipoint's receipt of an
opinion from Piper Marbury Rudnick & Wolfe LLP to the effect that the receipt of
VoiceStream Holdings common stock by holders of Omnipoint common stock pursuant
to the VoiceStream Reorganization will be treated as described in Section 351 of
the Code. Assuming this is the case, then the exchange of Omnipoint Series E
preferred stock for stock of VoiceStream Holdings company will also be treated
as a transfer of property to VoiceStream Holdings described in Section 351 of
the Internal Revenue Code. The amount of gain recognized by the holders of the
East/West common stock will depend on whether the persons who hold stock of
Omnipoint prior to the VoiceStream reorganization "control" VoiceStream Holdings
after the VoiceStream reorganization. The persons who hold stock of Omnipoint
prior to the VoiceStream reorganization will "control" VoiceStream Holdings
after the VoiceStream reorganization if such persons own, actually or
constructively, under the rules set forth in Section 304(c) of the Internal
Revenue Code, at least 50% of VoiceStream Holdings voting stock or at least 50%
of the value of VoiceStream Holdings stock after the VoiceStream reorganization.

     If the persons who hold stock of Omnipoint prior to the VoiceStream
reorganization do not "control" VoiceStream Holdings after the VoiceStream
reorganization, then the holders of East/West common stock will recognize gain
upon the receipt of their pro rata share of the standard election consideration
in exchange for Omnipoint Series E preferred stock in an amount equal to the
lesser of (i) the difference between the fair market value of the standard
election consideration received in the VoiceStream reorganization and the
holder's adjusted tax basis of the East/West common stock surrendered in the
East/West merger and (ii) the cash received in the VoiceStream reorganization.
Any gain will be taxed as capital gain. The tax basis of the VoiceStream
Holdings common stock received in the VoiceStream reorganization generally will
be equal to the tax basis of the East/West common stock surrendered in the
East/West merger, decreased by the amount of cash received in the VoiceStream
reorganization and increased by the amount of gain recognized in the VoiceStream
reorganization. In addition, the holding period of the VoiceStream Holdings
common stock will include the holding period for the East/West common stock
surrendered in the East/West merger.

     If the persons who hold stock of Omnipoint prior to the VoiceStream
reorganization "control" VoiceStream Holdings after the VoiceStream
reorganization, then except for cash received in lieu of fractional shares, the
holders of East/West common stock will be treated as having exchanged (i) a
portion of the Omnipoint Series E preferred stock for VoiceStream Holdings
common stock in a tax-free exchange and (ii) a portion of the Omnipoint Series E
preferred stock for cash. In this case, a holder of East/West common stock
should generally recognize capital gain or loss equal to the difference between
the amount of cash received in the VoiceStream reorganization and the holder's
basis in the portion of the Omnipoint Series E preferred stock that is
considered to be surrendered in exchange for cash.

     Alternative Treatment if The East/West Merger Does Not Qualify as a
Tax-Free Reorganization

     If the East/West merger does not qualify as reorganization within the
meaning of Section 368(a) of the Internal Revenue Code, then the East/West
merger will be a fully taxable transaction. In this case, a holder of East/West
common stock will recognize gain or loss equal to the difference between the
fair market value of the consideration received, or deemed received, in the
East/West merger and the holder's adjusted tax basis in the shares of East/West
common stock exchanged therefor. In this event, an East/West common
stockholder's holding period for the stock received in the East/West merger
would begin the day after the East/West merger.

     TAX CONSEQUENCES OF THE EAST/WEST MERGER IF THE VOICESTREAM REORGANIZATION
     OCCURS PRIOR TO THE EAST/WEST MERGER

     As described in detail under the heading "The East/West Merger
Agreement -- Conversion of East/West Common Stock", if the VoiceStream
reorganization occurs before the East/West merger, then each share of East/West
common stock will be converted at the effective time of the East/West merger
into the standard election consideration multiplied by the conversion ratio.

     Tax-Free Merger

     Assuming the continuity of interest requirement of Treasury Regulation
Section 1.368-1(e) is satisfied and the accuracy of the representations and
assumptions referred to above in the first six paragraphs of this section upon
which the opinion of Latham & Watkins will be based, the East/West merger will
constitute a reorganization within the meaning of Section 368(a) of the Internal
Revenue Code. The tax consequences of the exchange of a share of East/West
common stock for the standard election consideration multiplied by the
conversion ratio will be identical to the consequences described above under the
heading "Tax Consequences Of The East/West Merger If The VoiceStream
Reorganization occurs Immediately After The East/West Merger -- Tax-Free
Merger -- Tax-Free Merger; Deemed Issuance Of The Standard Election
Consideration In Exchange For East/West Common Stock."

     Alternative Treatment If The East/West Merger Does Not Qualify as a
Tax-Free Reorganization

     If the East/West merger does not qualify as a reorganization within the
meaning of Section 368(a) of the Internal Revenue Code, then the East/West
merger will be a fully taxable transaction. The tax consequences to a holder of
East/West common stock who exchanges a share of East/West common stock for the
standard election consideration multiplied by the conversion ratio in the case
where the East/West merger is not a reorganization within the meaning of Section
368(a) of the Internal Revenue Code are identical to the consequences described
above under the heading "Tax Consequences Of The East/West Merger If The
VoiceStream Reorganization Occurs Immediately After The East/West Merger;
Alternative Treatment If The East/West Merger Does Not Qualify As A Tax-Free
Reorganization."

     TAX CONSEQUENCES OF THE EAST/WEST MERGER IF THE VOICESTREAM REORGANIZATION
     AGREEMENT IS TERMINATED PRIOR TO THE CONSUMMATION OF THE EAST/WEST MERGER

     As described in more detail under the heading "The East/West Merger
Agreement -- Conversion of East/West Common Stock" if the VoiceStream
reorganization agreement is terminated prior to the completion of the East/West
merger, then each share of East/West common stock will be converted at the
effective time of the East/West merger into one share of Omnipoint common stock,
multiplied by the conversion ratio, provided that cash will be issued in lieu of
fractional shares of Omnipoint common stock.

     Tax-Free Merger

     Assuming the continuity of interest requirement of Treasury Regulation
Section 1.368-1(e) is satisfied and the accuracy of the representations and
assumptions referred to above in the first six paragraphs of this section upon
which the opinion of Latham & Watkins will be based, the East/West merger will
constitute a reorganization within the meaning of Section 368(a) of the Internal
Revenue Code. In this case, no gain or loss will be recognized by the holders of
East/West common stock upon the receipt of the Omnipoint common stock, except to
the extent of cash received in lieu of fractional shares of Omnipoint common
stock.

     A holder of East/West common stock who receives cash in lieu of a
fractional share of Omnipoint common stock will be treated as having received
the fractional share pursuant to the East/West merger and then as having
exchanged the fractional share for cash in a redemption by Omnipoint. Any gain
or

                                       37
<PAGE>   45

loss attributable to fractional shares will be capital gain or loss. The amount
of this gain or loss will be equal to the difference between the portion of the
holder's tax basis in the East/West common stock surrendered in the East/West
merger that is allocated to the fractional share and the cash payment received
in lieu thereof. Any gain or loss will be long-term capital gain or loss if the
East/West common stock that is deemed to be redeemed is considered to have been
held for more than one year at the effective time of the East/West merger.

     The tax basis of the Omnipoint common stock received by a holder of
East/West common stock in the East/West merger generally will be equal to the
tax basis of the East/West common stock surrendered in the East/West merger
(excluding any portion of the holder's tax basis allocated to fractional shares
of Omnipoint common stock).

     The holding period of the Omnipoint common stock received by each East/West
common stockholder in the East/West merger will include the holding period for
the East/West common stock surrendered in exchange therefor.

     Alternative Treatment if The East/West Merger Does Not Qualify as a
Tax-Free Reorganization

     If the East/West merger does not qualify as a reorganization within the
meaning of Section 368(a) of the Internal Revenue Code, then the East/West
merger will be a fully taxable transaction. The tax consequences to a holder of
East/West common stock who exchanges a share of East/West common stock for
Omnipoint common stock are identical to the consequences described above under
the heading "Tax Consequences Of The East/West Merger If The VoiceStream
Reorganization Occurs Immediately After The East/West Merger; Alternative
Treatment If The East/West Merger Does Not Qualify As A Tax-Free
Reorganization."

     TAX CONSEQUENCES TO HOLDERS OF EAST/WEST PREFERRED STOCK

     A holder of East/West preferred stock will recognize gain or loss on the
acquisition of its East/West preferred stock. Except to the extent of cash
received as a result of accrued but unpaid dividends (which should be taxed as a
receipt of a dividend), a holder of East/West preferred stock will recognize
gain or loss in amount equal to the difference between the cash received in
exchange for the holder's East/West preferred stock and the holder's adjusted
tax basis in such stock. This gain or loss should be capital and it should be
long-term capital gain or loss if a holder of East/West preferred stock holding
period in the stock is more than one year.

     REPORTING REQUIREMENTS AND BACKUP WITHHOLDING

     If the East/West merger qualifies as a tax-free reorganization, each holder
of East/West common stock receiving stock as a result of the East/West merger
will be required to retain records set forth in Treasury Regulations and file
with its federal income tax return a statement setting forth facts that relate
to the East/West merger.

     Back-up withholding at a rate of 31% may apply to cash payments received by
East/West common stockholders unless the recipient:

     - is a corporation or other exempt recipient and when required demonstrates
       this fact or

     - provides a correct taxpayer identification number, certifies as to no
       loss to exemption from back-up withholding and otherwise complies with
       applicable requirements of the backup withholding rules.

A stockholder who does not provide East/West with its correct taxpayer
identification number may be subject to penalties imposed by the Internal
Revenue Service. Any amounts withheld under the back-up

                                       38
<PAGE>   46

withholding rules may be allowed as a refund or credit against the stockholder's
federal income tax liability provided that the required information is furnished
to the Internal Revenue Service.

DELISTING AND DEREGISTRATION OF EAST/WEST COMMON STOCK; LISTING OF OMNIPOINT
COMMON STOCK OR VOICESTREAM HOLDINGS COMMON STOCK ISSUED IN CONNECTION WITH THE
MERGER

     East/West Class A common stock currently is listed for quotation on the OTC
Bulletin Board under the symbol "EWCM." Upon consummation of the merger,
East/West Class A common stock will be delisted from the OTC Bulletin Board and
deregistered under the Securities Exchange Act of 1934. Omnipoint common stock
is listed and traded on the Nasdaq stock market under the symbol "OMPT."
VoiceStream Holdings common stock is expected to be listed and traded on the
Nasdaq stock market under the symbol "VSTR." Following the merger, East/West
stockholders will be instructed to exchange their outstanding stock certificates

stock, Omnipoint common stock, or a combination of cash and VoiceStream Holdings
common stock. See "The East/West Merger Agreement -- Exchange of Certificates."

RESALES OF OMNIPOINT SERIES E PREFERRED STOCK, VOICESTREAM HOLDINGS COMMON
STOCK, OR OMNIPOINT COMMON STOCK ISSUED IN CONNECTION WITH THE EAST/WEST MERGER;
AFFILIATE AGREEMENTS

     Omnipoint Series E preferred stock, VoiceStream Holdings common stock or
Omnipoint common stock issued in connection with the East/West merger will be
freely transferable, except that shares of Omnipoint Series E preferred stock,
VoiceStream Holdings common stock or Omnipoint common stock received by persons
who are deemed to be "affiliates," as such term is defined by Rule 144 under the
Securities Act of 1933, of East/West at the effective time of the merger may be
resold by them only in transactions permitted by the resale provisions of Rule
145 under the Securities Act of 1933 or as otherwise permitted under the
Securities Act of 1933.

DISSENTERS' RIGHTS OF APPRAISAL


     The following is a summary of the principal steps that a stockholder of
East/West must take to exercise appraisal rights. This summary does not purport
to be complete and all East/West stockholders are encouraged to read Section 262
of the Delaware General Corporation Law, which is attached as Annex B. Failure
to take any one of the required steps may terminate the stockholder's appraisal
rights under the Delaware General Corporation Law. Because of the complexity of
the procedures in exercising appraisal rights, stockholders who exercise such
rights should seek the advice of legal counsel. All references in Section 262
and in this summary to a "stockholder" or "holder" are to the record holder of
the shares of East/West preferred stock or East/West common stock as to which
appraisal rights are asserted.



     Under Section 262 of the Delaware General Corporation Law, any record
holder of East/West common stock who does not wish to accept the shares of
Omnipoint Series E Preferred Stock, Omnipoint common stock, or a combination
VoiceStream Holdings common stock and cash, as applicable, for his, her or its
shares of East/West common stock, as provided in the East/West merger agreement,
has the right to seek an appraisal of, and to be paid the fair value for, his,
hers or its shares of East/West common stock if the stockholder complies with
the provisions of Section 262. Omnipoint's obligation to effect the East/West
merger is conditioned on the holders of no more than 10% of the outstanding
shares of East/West common stock exercising appraisal rights.


     Record holders of shares of East/West common stock who do not vote in favor
of the merger agreement and who otherwise comply with Section 262's procedures
will be entitled to appraisal rights under Section 262. These procedures are
summarized below. A person having a beneficial interest in shares of East/West
common stock held of record by or in the name of another person, such as a
broker

                                       39
<PAGE>   47

or nominee, must act promptly to cause the record holder to follow the steps
summarized below properly and in a timely manner to perfect appraisal rights.

     Under Section 262, a holder of shares of East/West common stock (the
"Appraisal Shares"), that follows the procedures set forth in Section 262 will
be entitled to have its Appraisal Shares appraised by the Delaware Court of
Chancery and to receive payment in cash of the "fair value" of such Appraisal
Shares together with a fair rate of interest, if any, as determined by the
Court.

     Under Section 262, if a merger agreement is to be submitted for approval at
a meeting of stockholders, the corporation, not less than 20 days prior to the
meeting, must notify each of its stockholders who was a holder on the record
date for the meeting of shares for which appraisal rights are available, of the
availability of appraisal rights, and must include in this notice a copy of
Section 262. This proxy statement/prospectus is the notice to the holders of
Appraisal Shares required by Section 262 and the text of Section 262 is attached
as Annex B to this proxy statement/prospectus.

     Any stockholder who wishes to exercise appraisal rights or who wishes to
preserve his, her or its right to do so should review the following description
and Annex B carefully. The failure to timely, properly and strictly comply with
the required procedures will result in the loss of appraisal rights.

     A holder of Appraisal Shares wishing to exercise appraisal rights must not
vote in favor of the adoption of the East/West merger agreement and must deliver
to East/West prior to the vote on the East/ West merger agreement at the
East/West special meeting, a written demand for appraisal of such holder's
Appraisal Shares. This written demand for appraisal is in addition to and
separate from any proxy or vote abstaining from or against the East/West merger.
This demand must reasonably inform East/West of the identity of the stockholder
and of the stockholder's intent thereby to demand appraisal of his, her or its
shares of East/West common stock. A holder of Appraisal Shares wishing to
exercise appraisal rights must be the record holder of the Appraisal Shares on
the date the written demand for appraisal is made and must continue to hold the
Appraisal Shares until the consummation of the merger. Accordingly, a record
holder of Appraisal Shares on the date the written demand for appraisal is made
who thereafter transfers any Appraisal Shares prior to consummation of the
merger, will lose appraisal rights for those Appraisal Shares.

     Only a record holder of Appraisal Shares is entitled to an appraisal of the
Appraisal Shares registered in that holder's name. A demand for appraisal should
be executed by or on behalf of the record holder as the holder's name appears on
the holder's stock certificates. If the Appraisal Shares are owned of record in
a fiduciary capacity, such as by a trustee, guardian or custodian, the demand
should be executed in that capacity, and if the Appraisal Shares are owned of
record by more than one owner, as in a joint tenancy or tenancy in common, the
demand should be executed by or on behalf of all joint owners. An authorized
agent, including one or more joint owners, may execute a demand for appraisal on
behalf of a record holder. However, in the demand the agent must identify the
record owner or owners and expressly disclose that, in executing the demand, the
agent is agent for such owner or owners. A record holder such as a broker who
holds Appraisal Shares as nominee for several beneficial owners may exercise
appraisal rights for the Appraisal Shares held for one or more beneficial owners
and not exercise rights for the Appraisal Shares held for other beneficial
owners. In this case, the written demand should state the number of Appraisal
Shares for which appraisal is sought. When no number of Appraisal Shares is
stated, the demand will be presumed to coverall Appraisal Shares in brokerage
accounts or other nominee forms. Those who wish to exercise appraisal rights
under Section 262 are urged to consult with their brokers to determine the
appropriate procedures for the making of a demand for appraisal by a nominee.

     All written demands for appraisal should be delivered to East/West
Communications, Inc., 350 Stuyvesant Avenue, Rye, New York 10580, Attention:
Secretary.

                                       40
<PAGE>   48

     Within 10 days after the effective time of the East/West merger, Omnipoint,
as the surviving corporation in the merger, will notify each stockholder who has
properly demanded appraisal rights under Section 262 and has not voted in favor
of the East/West merger agreement of the effective time of the East/West merger.

     Within 120 days after the effective time of the East/West merger, but not
thereafter, Omnipoint, as the surviving corporation in the East/West merger, or
any stockholder who has complied with the requirements of Section 262, and is
otherwise entitled to appraisal rights, may file a petition in the Delaware
Court of Chancery demanding a determination of the fair value of the Appraisal
Shares. Omnipoint is under no obligation to and has no present intention to file
an appraisal petition. Accordingly, it is the obligation of stockholders wishing
to exercise appraisal rights to file the petition within the time prescribed in
Section 262.

     Within 120 days after the effective time of the East/West merger, any
stockholder who has complied with the requirements for exercise of appraisal
rights will be entitled to receive from Omnipoint a statement setting forth the
aggregate number of Appraisal Shares not voted in favor of adoption of the
merger agreement and with respect to which demands for appraisal have been
received and the aggregate number of holders of such Appraisal Shares. A
stockholder must make a written request for this information. Omnipoint must
mail this statement within 10 days after the written request has been received
by it.

     If a petition for an appraisal is filed timely, after a hearing on the
petition, the Delaware Court of Chancery will determine the stockholders
entitled to appraisal rights and will appraise the "fair value" of their
Appraisal Shares. Under Section 262, fair value does not include any element of
value arising from the accomplishment or expectation of the East/West merger.
The Court will also determine a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. Stockholders considering seeking
appraisal should be aware that the fair value of their Appraisal Shares as
determined under Section 262 could be more than, the same as or less than the
value of the consideration they would receive under the East/West merger
agreement if they did not seek appraisal of their Appraisal Shares and that an
investment banking opinion as to fairness from a financial point of view is not
necessarily an opinion as to fair value under Section 262. The Delaware Supreme
Court has stated that" proof of value by any techniques or methods that are
generally considered acceptable in the financial community and otherwise
admissible in court" should be considered in the appraisal proceedings.

     The costs of the action may be determined by the Delaware Court of Chancery
and taxed upon the parties as the Court deems equitable in the circumstances.
Upon application of a stockholder, the Court may order that all or a portion of
the expenses incurred by any stockholder in an appraisal proceeding, including,
without limitation, reasonable attorneys' fees and the fees and expenses of
experts utilized in the appraisal proceeding, be charged pro rata against the
value of all of the Appraisal Shares entitled to appraisal.

     Any holder of Appraisal Shares who has duly demanded an appraisal in
compliance with Section 262 will not, after the effective time of the merger, be
entitled to vote the Appraisal Shares subject to such demand for any purpose or
to the payment of dividends or other distributions on those Appraisal Shares,
except, for dividends or other distributions payable to holders of record of
Appraisal Shares as of a record date prior to the effective time of the
East/West merger.

     If any stockholder who properly demands appraisal of his, her or its
Appraisal Shares under Section 262 fails to perfect, or effectively withdraws or
loses, his, her or its right to appraisal, as provided in Section 262, the
Appraisal Shares of such stockholder will be converted into the right to receive
the consideration receivable for those Appraisal Shares under the East/West
merger agreement, without interest. A stockholder will fail to perfect, or
effectively lose or withdraw, his, her or its right to appraisal if, among other
things, no petition for appraisal is filed within 120 days after the effective
time

                                       41
<PAGE>   49

of the merger, or if the stockholder delivers to East/West prior to the
effective time of the East/West merger or Omnipoint after the effective time of
the East/West merger a written withdrawal of his, her or its demand for
appraisal. An attempt to withdraw an appraisal demand made more than 60 days
after the effective time of the East/West merger will require the written
approval of Omnipoint and, once a petition for appraisal is filed, the appraisal
proceeding may not be dismissed as to any holder without court approval.

     Failure to follow the steps required by Section 262 for perfecting and
pursuing appraisal rights may result in the loss of such rights. If such rights
are lost a stockholder will be entitled to receive the consideration receivable
with respect to his, her or its appraisal shares in accordance with the
East/West merger agreement.

FORWARD LOOKING STATEMENTS MAY PROVE INACCURATE

     Omnipoint and East/West have made forward looking statements in this
information statement-prospectus and in the documents incorporated by reference
herein. These statements are subject to risks and uncertainties, and there can
be no assurance that such statements will prove to be correct. Forward-looking
statements include, among other things, assumptions as to how Omnipoint and
East/West may perform in the future.

     Additionally, the use of words like "believes," "anticipates," "expects" or
similar expressions involve forward-looking statements. For those statements,
Omnipoint and East/West claim the protection of the safe harbor for
forward-looking statements provided by the Private Securities Litigation Act of
1995. You should understand that a number of important factors, in addition to
those discussed elsewhere in this information statement-prospectus, could affect
the future results of operations and performance of Omnipoint and East/West, and
could cause those results and performance to differ materially from those
expressed in the forward-looking statements set forth herein. These factors
include, among others, regulatory, legal and other changes in the wireless
telecommunications industry environment generally, material adverse changes in
economic conditions in the markets in which Omnipoint and East/West operate, and
significant delays in the completion of the East/West merger.

                         THE EAST/WEST MERGER AGREEMENT

     In addition to the following summary of the East/West merger agreement, you
should read the entire East/West merger agreement which is attached as Annex A.

CONVERSION OF EAST/WEST COMMON STOCK

     If the East/West merger is consummated immediately prior to the VoiceStream
reorganization,


     - at the closing of the East/West merger, each share of East/West common
       stock will be converted into the right to receive one share of newly
       authorized Omnipoint Series E preferred stock. At the closing of the
       VoiceStream reorganization, each share of Series E preferred stock you
       received will be converted into (x) the standard election consideration
       to be received by holders of Omnipoint common stock in connection with
       the VoiceStream reorganization, multiplied by (y) the conversion ratio
       equal to 1,775,000, divided by the number of issued and outstanding
       shares of East/West common stock outstanding immediately prior to the
       closing of the East/West merger. No fractional shares of VoiceStream
       Holdings common stock will be issued pursuant to the VoiceStream
       reorganization. In lieu of the issuance of any fractional shares of
       VoiceStream Holdings common stock, cash equal to the product of such
       fractional share amount and the Closing Date Market Price will be paid to
       holders in respect of a fractional share of VoiceStream Holdings common
       stock that would otherwise be issuable. Payments with respect to
       fractional shares may come from the sale of the aggregate number of whole
       shares resulting from the foregoing.


     If the East/West merger is consummated after the VoiceStream
reorganization,


     - at the closing of the East/West merger, each share of East/West common
       stock will be converted into the right to receive (x) the standard
       election consideration to be received by holders of Omnipoint common
       stock in connection with the VoiceStream reorganization, multiplied by
       (y) the conversion ratio equal to 1,775,000, divided by the number of
       issued and outstanding shares of East/West common stock outstanding
       immediately prior to the closing of the East/West merger. No fractional
       shares of VoiceStream Holdings common stock will be issued in the East/
       West merger. In lieu of the issuance of any fractional shares of
       VoiceStream Holdings common stock, cash equal to the product of such
       fractional share amount and the Closing Date Market Price will be paid to
       holders in respect of a fractional share of VoiceStream Holdings common
       stock that would otherwise be issuable. Payments with respect to
       fractional shares may come from the sale of the aggregate number of whole
       shares resulting from the foregoing.


     If the VoiceStream reorganization agreement is terminated prior to the
East/West merger,


     - at the closing of the East/West merger, each share of East/West common
       stock will be converted into the right to receive (x) one share of
       Omnipoint common stock, multiplied by (y) the conversion ratio equal to
       1,775,000, divided by the number of issued and outstanding shares of
       East/West common stock outstanding immediately prior to the closing of
       the East/West merger. No fractional shares of Omnipoint common stock will
       be issued pursuant to the East/West merger. In lieu of the issuance of
       any fractional shares of Omnipoint common stock, cash equal to the
       product of such fractional share amount and the Merger Share Market Value
       will be paid to holders in respect of a fractional share of Omnipoint
       common stock that would otherwise be issuable. Payments with respect to
       fractional shares may come from the sale of the aggregate number of whole
       shares resulting from the foregoing.


EXCHANGE OF CERTIFICATES


     Omnipoint has designated Chase Mellon Shareholder Services, L.L.C. as
exchange agent for (i) the exchange of certificates representing shares of
East/West common stock for certificates representing:


                                       44
<PAGE>   52

(a) Omnipoint Series E preferred stock if the East/West merger is consummated
before the VoiceStream reorganization; (b) shares of VoiceStream Holdings common
stock if the East/West merger is consummated after the VoiceStream
reorganization; or (c) shares of Omnipoint common stock if the VoiceStream
reorganization agreement is terminated, and (ii) the payment of cash (x) to
holders of East/West common stock if the East/West merger is consummated after
the VoiceStream reorganization; (y) to holders of East/West preferred stock; and
(z) in lieu of fractional shares. Promptly after the effective time of the
East/West merger, the exchange agent will mail to each record holder of
certificates representing shares of East/West common stock or East/West
preferred stock, a letter of transmittal and instructions for surrendering the
certificates for exchange and payment. Holders of certificates representing
shares of East/West common stock who surrender their certificates to the
exchange agent together with a duly executed letter of transmittal, will receive
certificates representing the number of whole shares of Omnipoint Series E
preferred stock, VoiceStream Holdings common stock or Omnipoint common stock, as
the case may be. Holders of certificates representing shares of East/West
preferred stock who surrender their certificates to the exchange agent together
with a duly executed letter of transmittal, will receive cash in the amount of
$1,000 per share of East/West preferred stock plus all accrued and unpaid
dividends thereon. The surrendered certificates will be canceled.

     Failure to Exchange


     One year after the effective time of the East/West merger, Omnipoint may
require the exchange agent to deliver to Omnipoint all unclaimed cash and shares
of Omnipoint Series E preferred stock or Omnipoint common stock, as the case may
be. Thereafter, East/West stockholders must look only to Omnipoint for payment
of their consideration on their East/West stock.


     No Further Registration or Transfer

     At the effective time of the East/West merger, there will be no further
registration of transfers of shares of East/West common stock or East/West
preferred stock on the stock transfer books of East/West.

     Dividends and Distributions

     No dividends or other distributions declared or made after the effective
time of the East/West merger on shares of East/West common stock will be paid to
the holder of any unsurrendered certificate for the shares of Omnipoint Series E
preferred stock or Omnipoint common stock, as the case may be, that the holder
is entitled to receive, and no cash payment in lieu of fractional shares will be
paid to any such holder until the holder surrenders such certificate as provided
above. Upon surrender of the certificate, Omnipoint will pay to the holder,
without interest, any dividends or distributions with respect to such shares of
Omnipoint Series E preferred stock or Omnipoint common stock that have become
payable between the effective time of the East/West merger and the time of such
surrender.

     Lost Certificates

     A stockholder must provide an appropriate affidavit to Omnipoint if any
certificates are lost, stolen or destroyed, in order to receive consideration
for such certificates. Omnipoint may require the owner of such lost, stolen or
destroyed certificates to deliver a bond as indemnity against any claim that may
be made against Omnipoint or the exchange agent with respect to any such
certificates.

     Withholding Rights

     Each of Omnipoint, the exchange agent and East/West (to the extent any
shares of East/West preferred stock is redeemed by East/West pursuant to the
East/West merger agreement) is entitled to deduct and withhold from the
consideration payable to any holder of certificates the amounts Omnipoint,

                                       45
<PAGE>   53

the exchange agent or East/West is required to deduct and withhold from such
consideration under the Internal Revenue Code or any provision of state, local
or foreign tax law. Any amounts withheld will be treated as having been paid to
the holder of the shares of East/West common stock or East/West preferred stock.

     Holders of East/West common stock and East/West preferred stock should not
send in their certificates until they receive a transmittal letter from the
exchange agent, Chase Mellon Shareholder Services, L.L.C.

TREATMENT OF EAST/WEST PREFERRED STOCK

     At the closing of the East/West merger, each share of East/West preferred
stock will be converted into the right to receive cash in the amount of $1,000
plus accrued and unpaid dividends. As of the effective time of the East/West
merger, all such shares of East/West preferred stock shall no longer be
outstanding and shall automatically be canceled and retired and shall cease to
exist.

CERTAIN RIGHTS OF OMNIPOINT, VOICESTREAM AND VOICESTREAM HOLDINGS UNDER THE
EAST/WEST MERGER AGREEMENT

     Under the East/West merger agreement, each of Omnipoint, VoiceStream and
VoiceStream Holdings is permitted, in its sole discretion, to take (or not take)
any action permitted by the VoiceStream reorganization agreement or any action
it deems necessary in order to consummate the VoiceStream reorganization,
fulfill the closing conditions in the VoiceStream reorganization agreement or to
ensure that the receipt of VoiceStream Holdings common stock by Omnipoint
stockholders pursuant to the VoiceStream reorganization will be tax-free to such
Omnipoint stockholders. Any such action would not be considered a breach by such
party of the East/West merger agreement, the supplemental agreement, or any
other document to which such party is a party (each, a "Related Agreement"). If,
in the absence of the foregoing, the action would have caused a material breach
of a Related Agreement by such party, that party has the right to cure the
breach within 30 days of written notice of the breach. If the party fails to
cure the breach, then East/West will have the right for the following 30 days to
terminate the East/West merger agreement. If East/West elects to terminate the
East/West merger agreement under this provision, East/West has the option to
require that Omnipoint purchase 250,000 shares of East/West Class A common stock
at a per share purchase price of $20 for an aggregate purchase price of
$5,000,000 on substantially similar terms and conditions as the securities
purchase agreement.

FEES TO GABELLI AND COMPANY, INC.


     Gabelli and Company, Inc. has provided certain services to East/West in
connection with the transactions contemplated by the securities purchase
agreement and the East/West merger agreement. In return for these services, if
the East/West merger and the VoiceStream reorganization both are completed,
Gabelli and Company, Inc. is entitled to receive 20,625 shares of VoiceStream
Holdings common stock and cash equal to $200,000. If, on the other hand, the
East/West merger is completed and the VoiceStream reorganization agreement has
been terminated, then Gabelli and Company, Inc. will receive 25,000 shares of
Omnipoint common stock. If the East/West merger is not completed, Gabelli and
Company, Inc. is entitled to receive only a fee of $150,000 in cash from
East/West for services performed in connection with the transactions
contemplated by the securities purchase agreement. The majority of Gabelli and
Company, Inc.'s outstanding securities is beneficially owned by Mario J.
Gabelli, a director of East/West.

                          THE VOICESTREAM TRANSACTIONS

OVERVIEW

     Set forth below is certain information concerning the VoiceStream
reorganization, the Aerial reorganization and certain related transactions.
These summaries are qualified in their entirety by reference to the VoiceStream
disclosure statement and the annexes and exhibits thereto included with this
proxy statement/prospectus. While you will not be entitled to vote on the
approval any of these transactions, you should consider them carefully in light
of the fact that if you continue to hold shares of East/West common stock at the
time of the East/West merger, and the VoiceStream reorganization occurs at such
a time as you hold any Omnipoint securities received as a result of the
East/West merger, you will become stockholders of VoiceStream Holdings.

     THE VOICESTREAM REORGANIZATION

     On June 23, 1999, Omnipoint entered into the VoiceStream reorganization
agreement with VoiceStream and VoiceStream Holdings. Among other things, the
VoiceStream reorganization agreement provides for the mergers of separate
subsidiaries of VoiceStream Holdings with and into Omnipoint and VoiceStream.

     Upon completion of these proposed mergers, VoiceStream and Omnipoint will
both become wholly owned subsidiaries of VoiceStream Holdings. The VoiceStream
reorganization agreement provides that at the closing of the VoiceStream
reorganization, each share of Omnipoint common stock will be converted into the
right to receive 0.825 shares of VoiceStream Holdings common stock, plus $8 in
cash, or the equivalent value of all cash or all VoiceStream Holdings common
stock.

     VoiceStream, Omnipoint, and a number of their respective major stockholders
entered into an agreement whereby:

     - certain major Omnipoint stockholders have agreed to vote or cause to be
       voted the number of shares of Omnipoint common stock beneficially owned
       by them at the time of the Omnipoint special meeting to consider the
       VoiceStream reorganization in favor of the VoiceStream reorganization;
       and

     - certain major VoiceStream stockholders have agreed to vote or cause to be
       voted the number of shares of common stock of VoiceStream beneficially
       owned by them at the time of the VoiceStream special meeting to consider
       the VoiceStream reorganization in favor of the VoiceStream
       reorganization.

In addition, both the VoiceStream board and the Omnipoint board have agreed to
recommend that their respective stockholders adopt, and approve the transactions
contemplated by, the VoiceStream reorganization agreement.

     THE AERIAL REORGANIZATION

     On September 17, 1999, VoiceStream entered into the Aerial reorganization
agreement with Aerial. Among other things, the Aerial reorganization agreement
provides for Aerial's merger with a subsidiary of VoiceStream Holdings.

     EFFECTS OF THE VOICESTREAM REORGANIZATION AND THE AERIAL REORGANIZATION


     The parties expect that each of the VoiceStream reorganization and the
Aerial reorganization will be closed immediately prior to the East/West merger.
Omnipoint is not a party to the Aerial reorganization and neither the
VoiceStream reorganization nor the Aerial reorganization is conditioned on the
completion of the other or conditioned on the completion of the East/West
merger.

RELATED TRANSACTIONS

     COOK INLET TRANSACTIONS

     In connection with the VoiceStream reorganization, Omnipoint will transfer
certain licenses and related assets to joint venture entities affiliated with
Cook Inlet. Because VoiceStream Holdings is prohibited from holding certain
licenses currently held by Omnipoint, two Cook Inlet entities, Cook
Inlet/VoiceStream GSM II PCS, LLC and Cook Inlet/VoiceStream GSM III PCS, LLC,
will hold these licenses. Cook Inlet/VoiceStream GSM II and III are limited
liability companies and are eligible to hold C and F Block licenses issued by
the FCC. Cook Inlet, through its wholly owned subsidiary Cook Inlet GSM, Inc.,
is the managing member of each of Cook Inlet/VoiceStream GSM II and III.
VoiceStream Holdings entered into separate purchase agreements with Cook
Inlet/VoiceStream GSM II and III that will allow them to operate these licenses,
with technical assistance from VoiceStream Holdings, in the covered markets
using the VoiceStream brand.

     Among other things, the Cook Inlet/VoiceStream GSM II purchase agreement
provides that Omnipoint (then a subsidiary of VoiceStream Holdings) will
contribute to Cook Inlet/VoiceStream GSM II C and F Block licenses for 54 BTA
markets together with certain associated assets. In consideration for such
licenses and assets, Cook Inlet/VoiceStream GSM II will issue to Omnipoint Class
B membership interests in Cook Inlet/VoiceStream GSM II entitling Omnipoint to a
49.9% interest in Cook Inlet/VoiceStream GSM II. Cook Inlet/VoiceStream GSM II
will also assume certain of Omnipoint's liabilities associated with such
licenses and assets. In conjunction with the formation of Cook Inlet/VoiceStream
GSM II and the Cook Inlet/VoiceStream GSM II purchase agreement, VoiceStream
Holdings will grant to Cook Inlet certain rights to exchange Cook Inlet's
interest in Cook Inlet/VoiceStream GSM II for VoiceStream Holdings common stock
during the 30-day period beginning five years after the issuance of the licenses
to Cook Inlet/VoiceStream GSM II.

     Among other things, the Cook Inlet/VoiceStream GSM III purchase agreement
provides that Omnipoint will contribute to Cook Inlet/VoiceStream GSM III
certain C Block licenses for 34 BTA markets. In consideration for such
contribution, Cook Inlet/VoiceStream GSM III will issue to Omnipoint Class B
membership interests in Cook Inlet/VoiceStream GSM III entitling Omnipoint to a
49.9% interest in Cook Inlet/VoiceStream GSM III. Cook Inlet/VoiceStream GSM III
will also assume certain of Omnipoint's liabilities associated with such
licenses. In conjunction with the formation of Cook Inlet/VoiceStream GSM III
and the Cook Inlet/VoiceStream GSM III purchase agreement, VoiceStream Holdings
will grant to Cook Inlet certain rights to exchange Cook Inlet's interest in
Cook Inlet/VoiceStream GSM III for VoiceStream Holdings common stock during the
30-day period beginning five years after issuance of the licenses to Cook
Inlet/VoiceStream GSM III.

     HUTCHISON INVESTMENTS

     At the same time that Omnipoint entered into the VoiceStream reorganization
agreement, Hutchison Telecommunications, Hutchison PCS (USA) and VoiceStream
Holdings entered into agreements providing for the purchase by Hutchison PCS
(USA) of VoiceStream Holdings common stock for a purchase price of $29 per share
and shares of VoiceStream Holdings 2.5% Convertible Junior Preferred Stock, for
a purchase price of $100,000 per share. The total purchase price of the
VoiceStream Holdings common stock and the VoiceStream Holdings 2.5% Convertible
Junior Preferred Stock will be $957 million, consisting of $807 million in cash
and $150 million in shares of Omnipoint's Series A Preferred Stock, acquired
from Omnipoint by Hutchison PCS (USA).

     In accordance with a securities purchase agreement dated June 23, 1999,
Hutchison PCS (USA) and VoiceStream invested a combined total of $300 million in
Omnipoint by purchasing shares of Series A Preferred Stock. The Series A
Preferred Stock (or all shares of its common stock obtained prior to the
VoiceStream reorganization on conversion of Series A Preferred Stock) held by
Hutchison PCS (USA) will be exchanged at the closing of the VoiceStream
reorganization for VoiceStream

                                       53
<PAGE>   61

Holdings common stock at a conversion price of $29 per share. Hutchison PCS
(USA) has the right to determine the allocation between VoiceStream Holdings
common stock and VoiceStream Holdings 2.5% Convertible Junior Preferred Stock
that it will hold so long as it holds at least 18.6% of the total number of
outstanding shares of VoiceStream Holdings common stock immediately after the
closing of the VoiceStream reorganization. If the entire $957 million is used to
purchase (or is converted into) VoiceStream Holdings common stock, Hutchison
will have purchased an aggregate of 33 million shares of VoiceStream Holdings
common stock in connection with the Hutchison Investments. The Hutchinson
Entities, which are already major stockholders of VoiceStream, assuming the
completion of the VoiceStream reorganization, are expected to be significant
stockholders in VoiceStream Holdings. In connection with the $957 million
Hutchison investments, Hutchison PCS (USA) and certain of its affiliates entered
into a standstill agreement with VoiceStream Holdings.

<PAGE>   62

ADDITIONAL VOICESTREAM CONDITIONS

     VoiceStream's obligation to complete the VoiceStream reorganization is
additionally conditioned upon the following:

     - its receipt of a legal opinion that the VoiceStream reorganization
       agreement and the transactions contemplated by the VoiceStream

       the holders of Western Wireless; and

     - fewer than 10% of VoiceStream stockholders or Omnipoint stockholders
       electing dissenters' rights.

     Further, VoiceStream is not required to close the transaction if:

       Holdings after the effective time; and

     - more than $200 million of Omnipoint's indebtedness either becomes due and
       payable prior to its stated maturity or is required to be redeemed or
       repurchased prior to its stated maturity.

     RIGHT TO TERMINATE

     The parties may terminate the VoiceStream reorganization agreement at any

            obligations under the VoiceStream reorganization agreement that
            resulted in the failure to timely complete the VoiceStream
            reorganization; or

          - there is a permanent legal prohibition to closing the VoiceStream
            reorganization;

            manner adverse to VoiceStream, its approval or recommendation of the
            VoiceStream reorganization, or fails to call the Omnipoint meeting;

          - Omnipoint's stockholders fail to give the necessary approvals at a

            covenant of the VoiceStream reorganization agreement;

          - Omnipoint is incapable of satisfying, in all material respects, its
            obligations under the VoiceStream reorganization agreement; or

          - Omnipoint breaches any representation or warranty that would cause a

            at and as of the effective time; and

                                       55
<PAGE>   63

     - by Omnipoint if:

          - the VoiceStream board fails to recommend, or withdraws or modifies
            in a manner adverse to Omnipoint, its approval or recommendation of
            the VoiceStream reorganization or fails to call the VoiceStream
            meeting;

          - VoiceStream is incapable of satisfying, in all material respects,
            its obligations under the VoiceStream reorganization agreement; or

            a representation or warranty to be incapable of being true and
            correct at and as of the effective time.

     If the VoiceStream reorganization agreement is terminated, it will become
void without any liability on the part of any party unless that party is in
willful breach of the VoiceStream reorganization agreement. However, the

       manner adverse to VoiceStream, its approval or recommendation of the
       VoiceStream reorganization or fails to call a special meeting in
       accordance with the VoiceStream reorganization agreement or Omnipoint
       materially and willfully breaches any obligation with respect to the
       non-solicitation of other acquisition proposals; or

     - VoiceStream terminates the VoiceStream reorganization agreement in
       circumstances where the following three conditions are met:

            reorganization;

          - prior to Omnipoint's special meeting a third party makes a proposal
            for an alternative transaction; and

          - within twelve months of the special meeting Omnipoint enter into an

OMNIPOINT'S INTERIM OPERATIONS

     You should be aware that, pending the completion of the VoiceStream
reorganization, Omnipoint is bound by covenants set forth in the VoiceStream

     - encumber or transfer any assets having a fair market value exceeding
       $5,000,000 in related transactions, or $10,000,000 in the aggregate;

     For a summary of additional risks posed by the VoiceStream reorganization,
you should also review and consider the risks identified under the heading "Risk
Factors -- Risks related to the VoiceStream reorganization" and elsewhere in
this offering memorandum.

VOICESTREAM HOLDINGS

     VoiceStream Holdings was incorporated in June 1999 as a Delaware
corporation to act as the parent company for VoiceStream and Omnipoint following
the VoiceStream reorganization. VoiceStream Holdings has not conducted any
activities other than in connection with its organization, capitalization,
financing, and the VoiceStream reorganization. Upon consummation of the
VoiceStream reorganization, Omnipoint and VoiceStream will be subsidiaries of
VoiceStream Holdings, and VoiceStream Holdings will change its name to
VoiceStream Wireless Corporation.

     VoiceStream Holdings' business initially will be the combined current
businesses of Omnipoint and VoiceStream (and Aerial, if the Aerial
reorganization is completed), and its assets will be the assets of Omnipoint and
VoiceStream and their subsidiaries (and of Aerial and its subsidiaries, if the
Aerial reorganization is completed), subject to the contribution of certain
assets to joint ventures with Cook Inlet, which are more fully described in
"-- Related Transactions -- Cook Inlet Transactions." VoiceStream, which was
spun-off from its former parent Western Wireless on May 3, 1999, currently uses
the VoiceStream brand name to provide PCS services in 11 major markets in the
western United States. VoiceStream holds PCS licenses covering approximately
62.6 million POPs. For the nine months ended September 30, 1999, VoiceStream had
revenues of $300.0 million and an operating loss of $225.2 million.

     After the VoiceStream reorganization (and assuming the closing of the
Aerial reorganization), VoiceStream Holdings and the joint venture entities in
which it will hold interests will be a leading provider of PCS in the United
States, operating fully digital PCS networks. Assuming that the VoiceStream
reorganization had occurred on September 30, 1999, VoiceStream Holdings'
networks would have served subscribers in 22 major markets in the U.S.,
including New York, Philadelphia, Detroit, Boston, Denver, Seattle/Tacoma,
Phoenix/Tucson, Portland, Salt Lake City and Indianapolis. In

                                       57
<PAGE>   65

addition, VoiceStream is currently constructing PCS networks in San Antonio and
Austin, which it expects to be operational in the fourth quarter of 1999. This
expanded footprint is expected to allow VoiceStream Holdings to offer its
customers an extensive "local" calling area and will help VoiceStream Holdings
compete against regional operators. Together with its interests in the four
joint venture entities controlled by Cook Inlet discussed above and other
smaller joint ventures in which VoiceStream Holdings will hold interests,
assuming the closing of both the VoiceStream reorganization and the Aerial
reorganization, VoiceStream Holdings will have access to broadband PCS licenses
covering over 220 million persons and 77% of the geography of the United States
and will serve customers through more than 6,200 operational cell sites.

     While it is expected that VoiceStream Holdings will be a strong national
competitor in the wireless communications industry, it will be subject to some
of the same risks and limitations to which Omnipoint, VoiceStream and Aerial are
subject and will be subject to the same competitive factors described in the
most recent annual report on Form 10-K/A of VoiceStream.

     The information with respect to VoiceStream and Aerial has not been
independently verified and neither Omnipoint nor East/West makes any
representation or warranty as to the accuracy and completeness of this
information. See "Risk Factors" and "Where You Can Find More Information."

                             BUSINESS OF OMNIPOINT

     Omnipoint is a leading provider of personal communications services and
developer of PCS technology. Omnipoint holds licenses to provide communications
services to approximately 100 million POPs in the U.S. Approximately 60% of
Omnipoint's POPs are located in a contiguous cluster stretching from Maine to
Virginia. Omnipoint also hold licenses covering Detroit, Miami, St. Louis and
other parts of the U.S. On the basis of POPs, Omnipoint is the fourth largest
PCS licensee in the U.S. and its licenses cover six of the top 12, nine of the
top 20 and 23 of the top 50 cities in the U.S.

     Omnipoint employs GSM technology, which is the most widely used wireless
technology in the world with over 200 million users. Omnipoint is currently the
only GSM operator in each market in which it offers service. Omnipoint currently
operates in New York, New England, south Florida and the Midwest. Since 1996,
Omnipoint has aggressively built out its licenses and currently cover and market
to approximately 46 million POPs, including all major markets in the
northeastern United States from Boston to Delaware, as well as southern Florida
from Palm Beach to Key West, and certain Midwest markets, which include the
greater Detroit, Indianapolis, and Wichita markets. Omnipoint provides service
in the Harrisburg, York, and Lancaster, Pennsylvania markets through a joint
venture with D&E Communications. Omnipoint intends to continue its aggressive
build-out through both wholly-owned affiliates and joint ventures. Additionally,
Omnipoint offers out of network roaming in over 3,600 North American cities
(including Canada), through roaming agreements with members of the North
American GSM Alliance, and worldwide, through active roaming agreements with
over 100 carriers in 53 countries.

     PCS service offerings available from Omnipoint include voice
communications, caller ID, call forwarding, call waiting, voice activated
dialing, fax storage and retrieval, internet access, short messaging, numeric
paging, and information services including, but not limited to, stock quotes,
news, weather and sports scores. Every activated handset has its own internet
address and is capable of receiving and sending internet e-mail up to 160
characters long.

     Through its subsidiary OTI, Omnipoint is also a developer and supplier of
wireless communication technologies, products and engineering services. OTI,
with an ongoing staff of more than 120 people (adjusted for the employees
transferred as a result of OTI's joint venture with Siemens), will continue to
operate its other business divisions independently of the new joint venture.
Other OTI technology businesses include the PCS Infrastructure Products
division, which develops base station equipment for wireless E911 and other
location-based services for GSM infrastructure providers, and the Wireless
Solutions Division, which provides GSM-based solutions such as the Redhawk OSM
data terminal unit and the Eagle OEM module which are used to integrate GSM
solutions directly into wireless applications such as telematics and telemetry.
OTI is also working on next-generation wireless products and systems including
GPRS (General Packet Radio Systems) wireless packet systems.

     Omnipoint was incorporated as a Delaware corporation in June, 1987 and has
its principal executive offices at 3 Bethesda Metro Center, Suite 400, Bethesda,
Maryland 20814 (telephone number (301) 951-2500). For further information

     EAST/WEST MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                              OR PLAN OF OPERATION

     East/West is a development stage company with no significant results of
operations to date. East/West holds five 10 MHz PCS licenses to serve a
population of approximately 21 million, including two of the top ten markets,
Los Angeles and Washington, D.C., plus Sarasota, Florida, Reno, Nevada and Santa
Barbara, California. The total cost of these licenses was approximately $19
million, after a 25% bidding credit provided by the FCC. Eighty percent of the
cost of the licenses (or $15.2 million) was financed over ten years by the FCC,
with only payments of interest during the first two years after award of the
licenses.


     On October 22, 1999, East/West sold 300,000 shares of our Class A common
stock to Omnipoint Corporation for a total of $3,000,000. In addition, on that
date, East/West signed an Agreement and Plan of Merger in which all of its
outstanding common stock, both Class A and Class B, at consummation of the
merger will be exchanged for either Series E preferred stock, common stock of
Omnipoint, or a combination of cash and common stock of VoiceStream Holdings, as
discussed below. On January 5, 2000, East/West sold 100,000 shares of our Class
A common stock to affiliates of Weiss, Peck & Greer, L.L.C. for a total of
$3,325,000.


     Omnipoint is also a party to an Agreement and Plan of Reorganization, dated
as of June 23, 1999, by and among Omnipoint, VoiceStream Wireless Corporation
and VoiceStream Wireless Holding Corporation, pursuant to which Omnipoint will
be merged with a newly formed, wholly-owned subsidiary of VoiceStream Holdings,
and each share of common stock of Omnipoint will be converted into the right to
receive 0.825 shares of common stock of VoiceStream Holdings and $8.00 in cash,
subject to the right of the holders of outstanding shares of Omnipoint common
stock to elect to receive stock and cash consideration in different proportions.


     It is anticipated that the East/West merger will be consummated immediately
prior to the VoiceStream reorganization. Under the terms and conditions of the
East/West merger, if the East/West merger is consummated prior to the
VoiceStream reorganization, (i) in the East/West merger, each outstanding share
of Class A common stock and Class B common stock of East/West will be converted
into one share of newly-authorized Series E preferred stock of Omnipoint and
(ii) each share of Omnipoint's Series E preferred stock received by the holders
of the East/West common stock in the East/West merger will be converted in the
VoiceStream reorganization into (x) 0.825 shares of common stock of VoiceStream
Holdings and $8.00 in cash, which is the "standard election consideration,"
multiplied by (y) a conversion ratio equal to 1,775,000, divided by the number
of shares of East/West common stock outstanding immediately prior to
consummation of the East/West merger. Currently, there are 4,839,374 shares of
East/West common stock issued and outstanding, taking into account the sale of
300,000 shares to Omnipoint on October 22, 1999 and 100,000 shares to affiliates
of Weiss, Peck & Greer, L.L.C. on January 5, 2000. If the VoiceStream
reorganization occurs prior to the consummation of the East/West merger, in the
East/West merger, each share of East/West common stock will be converted into
the right to receive (x) the standard election consideration, multiplied by (y)
the conversion ratio described above. Under each of the scenarios described
above, upon consummation of the East/West merger, each outstanding share of
preferred stock of East/West will be converted in the East/West merger, into the
right to receive in all events cash in the amount of $1,000 per share, plus
accrued and unpaid dividends.


     As evidenced by the sale of shares to Omnipoint and the East/West merger,
East/West believes that its PCS licenses have substantial value. However, should
the merger with Omnipoint not take place, we have not yet adopted an alternative
business plan or determined an alternative methodology for how to obtain
additional financing for our operations because of uncertainties relating to
PCS, which makes evaluation difficult, including without limitation the newness
of PCS, financing, affiliation and technology issues and the financial problems
of certain C-Block licensees. Therefore, should the East/

                                       60
<PAGE>   68

West merger not be consummated, East/West has not yet determined whether to
develop its PCS licenses on its own, joint venture the licenses with other PCS
wireless telephone license holders or operators or others, or sell some or all
of its PCS licenses. East/West expects to continually evaluate these factors and
to adopt a plan or plans once the financing, regulatory and market aspects of
PCS are less uncertain. Our principal expense to date has been interest,
including commitment fees, plus minor administrative expenses.


     If the East/West merger is not consummated and unless East/West sells its
PCS business or joint venture East/West's PCS licenses with another entity that
has the capacity to provide substantial funds, East/West will need to raise
substantial capital to fund our installment payments to the FCC and the build
out of our PCS licenses. We do not have a reliable estimate of the cost to build
out our PCS licenses, should we determine to do so, but it is likely to be
substantial.


     Of the $3,000,000 of proceeds from the sale of shares of East/West common
stock to Omnipoint, $1,656,000 million was used to pay all past and currently
due interest and principal payments, including penalties, on our FCC obligation.
This represented payments that were originally due on April 30, 1999, July 31,
1999 and October 31, 1999. Under the government financing of part of our winning
bids for its PCS licenses, we will be required to pay the FCC approximately $2.6
million in the year 2000 and $2.4 million in each of the next seven years.

     The following are the scheduled interest and principal payments over the
next two fiscal years:

     Under FCC rules, scheduled payments may be delayed for up to 90 days upon
payment of a 5% penalty and for 90-180 days upon payment of a 15% penalty.

     If the merger with Omnipoint is not consummated, we will have to raise
funds within the next year in order to make interest payments on the government
financing and for working capital and general corporate purposes. The report of
our independent auditors with respect to our financial statements as of December
31, 1998 and 1997, for the years ended December 31, 1998 and 1997 and the period
from July 26, 1996 (inception) to December 31, 1998 contains a paragraph
indicating that substantial doubt exists as to our ability to continue as a
going concern. Among the factors cited by the auditors as raising substantial
doubt as to our ability to continue as a going concern is that, with respect to
the periods covered, we have incurred losses since inception and have not yet
adopted a business plan or determined how to finance our operations and will
need to obtain capital in order to fund our interest and principal payment
obligations and for working capital and general corporate purposes.

LIQUIDITY AND CAPITAL RESOURCES


     Pro forma for the sale of shares to Omnipoint and to the affiliates of
Weiss, Peck & Greer, L.L.C. and the principal payments of debt in October, the
principal amount of debt on September 30, 1999 was


                                       61
<PAGE>   69


$14,897,000 and shareholders equity was $6,661,000. During the period from July
26, 1996 (inception) to September 30, 1999, we had no revenues or operating
profits and cannot predict when East/West may have any revenues or operating
profits.


     In April 1997, the FCC suspended interest payments on its financings
through March 31, 1998. On March 24, 1998, the FCC indicated that such interest
would be resumed not earlier than 90 days subsequent to the publication in the
Federal Register of an order on reconsideration. Such publication was made on
April 8, 1998, requiring cumulative suspended interest payments to be made in
eight quarterly installments of $100,686 each beginning on July 31, 1998. Also
on that date, the accrued interest of $311,324, from the date the interest
suspension ended, March 31, 1998, until July 31, 1998. Through September 30,
1999, East/West had made interest payments totaling $1,212,000 and, as noted
above, in October 1999 East/West made additional payments of $1,656,000.

     During May 1999, we offered, at no cost to the holders of its Class A
common stock, a non-transferrable right to purchase up to 443,050 shares of
Class A common stock. The rights entitle shareholders to purchase one additional
share of Class A common stock for every four shares of Class A common stock held
at $1.50 per share. In addition, we offered rights to purchase 444,825 shares of
Class B common stock at a price of $1.50 per share to the current owner of our
Class B common stock. The Class A and Class B shareholders exercised these
rights on June 23, 1999, and the net proceeds from the sale of both Class A and
Class B common shares was $1,202,000.

     On October 22, 1998 and April 29, 1999, East/West borrowed $300,000 and
$400,000, respectively, from certain of our directors. Such funds were used to
make the required payments on our FCC obligations. On July 22, 1999, these loans
were repaid by the Company, along with accrued interest in the amount of
$12,164, from the proceeds of the rights offering.

                             BUSINESS OF EAST/WEST

     East/West holds five 10 MHz personal communications services ("PCS")
licenses to serve a population of approximately 21 million, including two of the
top ten markets, Los Angeles, California and Washington D.C., plus Sarasota,
Florida, Reno, Nevada and Santa Barbara, California. The total cost of these
licenses was approximately $19 million, after a 25% bidding credit provided by
the Federal Communications Commission. Eighty percent (80%) of the cost of the
licenses (or $15.2 million) was financed over ten years by the FCC, with only
payments of interest during the first two years.

     East/West believes that there are significant growth opportunities in the
wireless telecommunications industry and that our PCS licenses have substantial
potential. According to the Cellular Telecommunications Industry Association,
there are 60.8 million wireless telephone subscribers in the United States,
representing an overall wireless penetration rate of 22.4% and a subscriber
growth rate of 24.9% from June 30, 1997. Paul Kagan Associates, Inc., a leading
telecommunications consultant, estimates that the number of cellular and PCS
wireless service subscribers will reach 98.4 million by 2001. East/West believes
that a significant portion of the predicted growth in the consumer market for
wireless telecommunications will result from anticipated declines in costs of
service, increased functional versatility, and increased awareness of the
productivity, convenience and privacy benefits associated with the services
provided by PCS providers, which are the first direct wireless competitors of
cellular providers to offer all-digital mobile networks. East/West also believes
that the rapid growth of notebook computers and personal digital assistants,
combined with emerging software applications for delivery of electronic mail,
fax and database searching, will contribute to the growing demand for wireless
services.

     East/West has not adopted a business plan or determined how to finance our
operations, due in part to uncertainties relating to PCS, which makes evaluation
difficult, including the newness of PCS, financing, affiliation and technology
issues and the financial problems of certain C-Block licensees.

     East/West's address is 350 Stuyvesant Avenue, Rye, New York 10580.
East/West's telephone number is (914) 921-6300.

                     DESCRIPTION OF OMNIPOINT CAPITAL STOCK

     The following is a summary of the material terms of Omnipoint's capital
stock. Because it is only a summary, it does not contain all information that
may be important to you. Therefore, you should read carefully the more detailed
provisions of Omnipoint's certificate of incorporation (as amended and restated)
and by-laws and the Deposit Agreement dated May 6, 1998 by and among Omnipoint,
HSBC Bank USA (formerly known as Marine Midland Bank, N.A.), as depositary, and
all holders from time to time of depositary receipts issued thereunder. For
information on how to obtain copies of Omnipoint's certificate of incorporation
and by-laws, see "Where You Can Find More Information."

GENERAL

     As of the date of this proxy statement/prospectus, Omnipoint's authorized
capital stock consists of 200,000,000 shares of Omnipoint common stock, par
value $.01 per share, 10,000,000 shares of preferred stock, $.01 par value per
share, of which (i) 12,500 shares have been designated as Omnipoint Series A
Non-Voting Convertible Preferred Stock, and (ii) 325,000 shares have been
designated as Omnipoint 7% Cumulative Convertible Preferred Stock. In connection
with the East/West merger, Omnipoint will designate a number of shares of Series
E preferred stock equal to the number of shares of East/West common stock
outstanding immediately prior to the East/West merger. No other classes of
capital stock are authorized or expected to be authorized under the Omnipoint
certificate of incorporation. The issued and outstanding shares of Omnipoint
common stock and Omnipoint preferred stock are duly authorized, validly issued,
fully paid and nonassessable.

COMMON STOCK

     Each holder of Omnipoint common stock is entitled to one vote for each
share of Omnipoint common stock held of record by such holder. Holders of
Omnipoint common stock, voting as a single class, are entitled to elect all of
the directors of Omnipoint. Matters submitted to stockholder approval generally
require a majority vote. Holders of Omnipoint common stock are entitled to
receive ratably such dividends as may be allowed under the various financing
agreements of Omnipoint and as declared by the Omnipoint board out of funds
legally available therefor. Upon Omnipoint's liquidation, dissolution or winding
up, holders of Omnipoint common stock would be entitled to share ratably in
Omnipoint's net assets after the payment of liquidating distributions to holders
of Omnipoint preferred stock. Holders of Omnipoint common stock have no
preemptive, redemption, conversion or other subscription rights.

     The registrar and transfer agent for the Omnipoint common stock is Chase
Mellon Shareholder Services, LLC.

PREFERRED STOCK

     The Omnipoint board has the power, without further vote of stockholders, to
authorize the issuance of up to 10,000,000 shares of Omnipoint preferred stock
and to fix and determine the terms, limitations and relative rights and
preferences of any shares of Omnipoint preferred stock. This power includes the
authority to establish voting, dividend, redemption, conversion, liquidation and
other rights of any such shares. Other than as set forth herein, there are no
shares of Omnipoint preferred stock currently outstanding.

  SERIES A NON-VOTING CONVERTIBLE PREFERRED STOCK

     Omnipoint has issued and outstanding 12,500 shares of Omnipoint Series A
Non-Voting Convertible Preferred Stock. Each share of Series A preferred stock
is deemed to be, and treated for all purposes relating to the declaration and
payment of dividends as, the number of shares of Omnipoint common stock into
which each share of the Series A preferred stock is then convertible. The
affirmative vote or

                                       66
<PAGE>   74

consent of the holders of at least 51% of the outstanding Series A preferred
stock is required for amendments to Omnipoint's certificate of incorporation
that would adversely affect the rights of holders of Series A preferred stock.
The holders of Series A preferred stock have no other voting rights, except as
provided by law or as set forth in the certificate of designation relating to
the Series A preferred stock.

  7% CUMULATIVE CONVERTIBLE PREFERRED STOCK; DEPOSITARY SHARES

     Omnipoint has issued and outstanding 325,000 shares of Omnipoint's 7%
Cumulative Convertible Preferred Stock, par value $0.01 per share. In addition,
there are 6,500,000 Depositary Shares outstanding. The shares of Omnipoint
Cumulative preferred stock are represented by Omnipoint depositary shares, each
share representing one twentieth of a share of Omnipoint Cumulative preferred
stock. Subject to the terms of a deposit agreement, each owner of an Omnipoint
Depositary Share is entitled to all the rights and preferences of the Omnipoint
Cumulative preferred stock represented thereby, and subject, proportionately, to
all of the limitations of the Omnipoint Cumulative preferred stock represented
thereby, contained in the certificate of designation related to the Cumulative
preferred stock summarized below.

     The liquidation preference per share of Omnipoint Cumulative preferred
stock is $1,000 per share. Holders of the Omnipoint Cumulative preferred stock
are entitled to receive cumulative annual dividends of 7% of the liquidation
preference per share payable quarterly. Except as required by law, holders of
Omnipoint Cumulative preferred stock have no voting rights unless dividends are
in arrears for six quarterly periods, in which case the holders of Omnipoint
Cumulative preferred stock have the right to elect two directors at the next
meeting of Omnipoint stockholders.

  SERIES E PREFERRED STOCK

     In connection with the East/West merger, Omnipoint will designate a number
of shares of Series E preferred stock equal to the number of shares of East/West
common stock outstanding immediately prior to the East/West merger. With respect
to dividends and voting rights, the proposed Series E preferred stock will have
the same rights as the Omnipoint common stock (as multiplied by the Conversion
Ratio). In terms of ranking, the Series E preferred stock will rank on parity
with the Omnipoint common stock.

                        COMPARISON OF STOCKHOLDER RIGHTS

     The following is a summary of the material differences between the rights
of holders of Omnipoint common stock and the rights of holders of East/West
common stock. Since both Omnipoint and East/ West are organized under the laws
of the state of Delaware, the differences arise from differences between various
provisions of the respective certificates of incorporation and bylaws of
Omnipoint and East/West and from Omnipoint's rights agreement.

     The following summary is qualified in its entirety by reference to the
Delaware General Corporation Law and the respective certificates of
incorporation and bylaws of East/West and Omnipoint and Omnipoint's rights
agreement. See "Description of Omnipoint Capital Stock" for a summary of a
number of other rights relating to Omnipoint common stock.

Omnipoint's 7% Cumulative Convertible Preferred Stock, and 12,500 have been
designated shares of Omnipoint's Series A Non-Voting Convertible Preferred

     The Omnipoint bylaws provide that the Omnipoint board shall consist of one
or more members as the Omnipoint board shall designate, with each director
serving until the subsequent annual meeting and until his successor is elected
and qualified, or until his death, resignation or removal. The number of
directors of Omnipoint currently designated is seven. The Omnipoint bylaws
provide that whenever the number of directors of Omnipoint is increased between
annual meetings of Omnipoint stockholders, a majority of the directors then in
office have the power to elect the new directors for the balance of the term and
until their successors are elected and qualified. Any decrease in the authorized
number of directors shall not become effective until the expiration of the term
of the directors then in office unless at the time of the decrease there shall
be vacancies on the Omnipoint board which are being eliminated by the decrease.


     East/West's certificate of incorporation and bylaws, as amended, provide
that the number of members of the East/West board of directors shall consist of
five unless otherwise determined by resolution of the board or by the
stockholders at the annual meeting of the stockholders and each director shall

an annual or special meeting of East/West stockholders may be taken without a
meeting, without prior notice and without a vote if a consent in writing setting

authorize the taking of such action at a meeting at which all shares entitled to
vote thereon were present and voted. Prompt notice of the taking of the action
without a meeting by less than unanimous written consent shall be given to those
East/West stockholders who have not consented in writing.

PREEMPTIVE RIGHTS/CONVERSION RIGHTS


     Omnipoint common stock has no preemptive rights enabling a holder to
subscribe for or receive shares of any class of stock of Omnipoint or any other
securities convertible into shares of any class of stock of Omnipoint under the
Omnipoint amended and restated certificate of incorporation. The East/West
common stock and preferred stock have no preemptive rights, and the East/West
preferred stock has or conversion rights provided, however, that Omnipoint has
been granted certain contractual preemptive rights in connection with its
purchase of 300,000 shares of East/West Class A common stock. Each share of
East/West Class B common stock shall automatically convert into one share of
East/West Class A common stock on the earlier of (i) July 1, 2007, or (ii)
fourteen days after the control group, as defined by the FCC, no longer needs to
control East/West as determined by the FCC, or (iii) such earlier date as
determined by the board.


INCREASE IN AUTHORIZED SHARES

     An amendment to the Omnipoint amended and restated certificate of
incorporation increasing or decreasing the capital stock must be approved by a
majority of the outstanding common stock. The stockholders of East/West may
alter, amend and rescind any or all of the certificate of incorporation of the
corporation only with the affirmative vote of the holders of the shares of Class
A common stock and Class B common stock representing the majority of the
aggregate voting power of all outstanding shares of East/West Class A common
stock and Class B common stock.

LIQUIDATION

     In the event of the liquidation or dissolution of Omnipoint, holders of
common stock are entitled to receive all assets available for distribution to
stockholders, subject to any preferential rights of any then outstanding shares
of preferred stock. In the event of the liquidation or dissolution of East/West,
holders of Class A and Class B common stock are entitled to receive all assets
available for distribution to stockholders, subject to any preferential rights
of any then outstanding shares of preferred stock.


                             SHAREHOLDER PROPOSALS



     Due to the contemplated consummation of the East/West merger, East/West
does not currently expect to hold a 2000 Annual Meeting of Stockholders, as
East/West common stock will not be publicly traded after the East/West merger.
If the East/West merger is not consummated and such a meeting is held,
stockholder proposals for inclusion in proxy materials for such meeting would
have to be submitted to East/West no later than February 5, 2000. Such proposals
must also meet the other requirements of the rules of the Securities and
Exchange Commission relating to stockholders' proposals.


                                 LEGAL MATTERS

     The validity of the Omnipoint securities to be issued in connection with
the East/West merger will be passed upon for Omnipoint by Piper Marbury Rudnick
& Wolfe LLP. It is a condition to the completion of the East/West merger, in
certain circumstances, that Omnipoint and East/West receive opinions from Piper
Marbury Rudnick & Wolfe LLP and Latham & Watkins, respectively, with respect to
the tax treatment of the East/West merger. See "The East/West Merger
Agreement -- Conditions to the East/West Merger" and The East/West
Merger -- Material Federal Income Tax Consequences of the East/West Merger."

                         REPORT OF INDEPENDENT AUDITORS

Shareholders and Board of Directors
East/West Communications, Inc.

     We have audited the accompanying balance sheets of East/West
Communications, Inc. (the "Company") a development stage enterprise, formerly
Aer Force Communications B, L.P., as of December 31, 1998 and 1997, and the
related statements of operations, changes in shareholders' equity (deficit), and
cash flows for the years ended December 31, 1998 and 1997 and the period from
July 26, 1996 (inception) to December 31, 1998. These financial statements are
the responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements based on our audits.

     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of the Company at December 31,
1998 and 1997, and the results of its operations and its cash flows for the
years ended December 31, 1998 and 1997 and the period from July 26, 1996
(inception) to December 31, 1998, in conformity with generally accepted
accounting principles.

     The accompanying financial statements have been prepared assuming East/West
Communications, Inc. will continue as a going concern. As more fully described
in Note 1, the Company has incurred losses since inception and has not yet
adopted a business plan or determined how to finance its operations and will
need to obtain capital in order to fund its interest and principal payment
obligations and for working capital and general corporate purposes. These
conditions raise substantial doubt about the Company's ability to continue as a
going concern. The financial statements do not include any adjustments to
reflect the possible future effects on the recoverability and classification of
assets or the amounts and classification of liabilities that may result from the
outcome of this uncertainty.

                         NOTES TO FINANCIAL STATEMENTS
                               DECEMBER 31, 1998

NOTE 1  ACCOUNTING POLICIES:

DESCRIPTION OF BUSINESS:


     East/West Communications, Inc. ("the Company") was incorporated on August
13, 1997, to succeed to the rights and obligations of Aer Force Communications
B, L.P. ("the Partnership"). The Partnership was formed in July 1996, to bid for
personal communications services ("PCS") licenses in the Federal Communications
Commission's ("FCC") F-Block auction. PCS is a second generation digital
wireless service utilizing voice, video or data devices that allow people to
communicate at anytime and virtually anywhere. Over the past three years, the
FCC auctioned off PCS licenses with a total of 120 MHz of spectrum, falling
within six separate frequency blocks labeled A through F. Frequency blocks C and
F were designated by the FCC as "entrepreneurial blocks." Certain qualifying
small businesses, including the Partnership, were afforded bidding credits in
the auctions as well as government financing of the licenses acquired. The
Partnership won five licenses in 1997 to provide personal communications
services over 10MHz of spectrum to a population of approximately 21 million,
including Los Angeles and Washington, D.C. Aer Force Communications, Inc. was
the General Partner of the Partnership with a 50.1% equity interest. Lynch PCS
Corporation F ("Lynch PCS F"), a wholly-owned subsidiary of Lynch Corporation
("Lynch"), a publicly held company, was the Limited Partner of the Partnership
with a 49.9% equity interest.


     On December 4, 1997, the Company succeeded to the assets and liabilities of
the Partnership under a plan where the General Partner received 50.1% of the
Common Stock of the Company (in the form of 100% of the Company's Class B Common
Stock) and Lynch PCS F received 49.9% of the Common Stock of the Company (in the
form of 100% of the Company's Class A Common Stock). Just prior to the
succession, the Partners made cash contributions totaling $250,000 (in
proportion to their respective equity interests) to the Partnership and the
Limited Partner contributed $4.5 million of its outstanding loan to the
Partnership's capital.

     Immediately thereafter, Lynch PCS F dividended 39.9% of the Common Stock of
the Company to Lynch which, in turn, dividended this interest to its
shareholders. In addition, Lynch PCS F transferred the remaining 10% of Common
Stock of the Company held by it to Gabelli Funds, Inc., an affiliate of the
Chairman and CEO of Lynch, in satisfaction of a previously incurred obligation.
Also at that time, Lynch PCS F converted the remaining principal amount of its
loan to the Partnership of $3,335,221 (after the capital contribution of
$4,500,000) into a redeemable preferred stock of the Company (see Note 6). Under
the terms of this conversion the Limited Partner's prior obligation to make
further loans to the Partnership was terminated.

BASIS OF PRESENTATION:

     The financial statements are prepared in conformity with generally accepted
accounting principles applicable to a development stage enterprise.

     The Company's financial statements have been prepared on a going concern
basis which contemplates the realization of assets and the satisfaction of
liabilities in the normal course of business and do not include any adjustments
to reflect the possible future effects on the recoverability and classification
of assets and the amount and classification of liabilities that may result from
the possible inability of the Company to continue as a going concern.

                       AER FORCE COMMUNICATIONS B, L.P.)
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

NOTE 1  ACCOUNTING POLICIES: -- (CONTINUED)
     The Company believes that its PCS licenses have substantial potential.
However, the Company has not yet adopted a business plan or determined how to
finance its operations because of uncertainties relating to PCS. Therefore, the
Company has not yet determined whether to develop its PCS licenses on its own,
to joint venture its licenses with other PCS or wireless telephone licensees or
operators, or to sell some or all of its licenses. The Company expects to
continually evaluate these factors and to adopt a business plan once the
financing, regulatory and market aspects of PCS are less uncertain.

     The Company has incurred losses since inception and will need to obtain
capital in order to fund its interest and principal payment obligations and for
working capital and general corporate purposes. There can be no assurance that
the Company can raise sufficient capital to fund its obligations and finance the
construction of its networks. Accordingly, the lack of funding creates
substantial doubt about the Company's ability to continue as a going concern.
Management has elected to defer payment of interest due on the loan payable to
the FCC which was due on October 31, 1998 in the amount of $337,658. The Company
intends, to make the required payment, including applicable penalties of
approximately $390,000 on or before April 29, 1999. However, if such payment is
not made, the Company will forfeit its rights to the licenses.

     Certain prior year amounts have been reclassified to conform to the current
year presentation.

CASH AND CASH EQUIVALENTS:

     Cash and cash equivalents for which the carrying amount approximates fair
value include highly liquid investments with a maturity of three months or less
at the time of purchase.

ADMINISTRATIVE SERVICES:

     The Company and the Partnership has never had any paid employees. Lynch PCS
F provided the Partnership, at its request, with certain services in connection
with the Partnership's bidding for PCS licenses in the FCC auction in late 1996
through early 1997. Aside from that matter, neither the General Partner nor
Lynch PCS F provided the Partnership or the Company with a substantial amount of
services. Neither partner charged the Partnership or the Company for the
services provided, as such amounts are not significant.

USE OF ESTIMATES:

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the carrying amounts of assets and liabilities and
disclosures at the date of the financial statements and the reported amounts of
expenses during the reporting period. Actual results could differ from those
estimates.

CAPITALIZED COSTS:

     Interest charges including commitment fees incurred prior to the granting
of the licenses have been expensed. Subsequent to the license grant dates, and
until operations commence, all interest charges (excluding penalty interest and
late fees) and commitment fees on outstanding loan balances will be capitalized.
These costs amounted to $2,188,626 and $1,240,434 at December 31, 1998 and 1997,

                                       F-8

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

NOTE 1  ACCOUNTING POLICIES: -- (CONTINUED)
respectively. Such costs include $1,845,150 and $897,267 of capitalized interest
at December 31, 1998 and 1997 respectively. Total interest charges amounted to
$947,883, $1,119,111, and $2,765,160 for the years ended December 31, 1998 and
1997 and the period from July 26, 1996 (inception) to December 31, 1998,
respectively.

     The cost of the PCS licenses (including capitalized costs) will be
amortized over a period, consistent with the industry practice, which will begin
when operations commence. Pursuant to FCC regulations, license holders are
required to commence providing service to one-third or the population within the
license area within five years from the date of award and two-thirds of the
population within ten years from the date of award. Such licenses may only be
transferred to other entities that meet the FCC requirements for F-Block license
holders during the first five years of the initial license term. Transfers of
such licenses to entities not meeting such requirements in years six through ten
of the initial license term will subject the Company to substantial unjust
enrichment penalties.

LOSS PER SHARE:

     In 1997, the Financial Accounting Standards Board issued SFAS No. 128,
"Earnings per Share," which was adopted by the Company in 1997 upon the issuance
of its common stock. Basic loss per common share is calculated by dividing net
loss by the weighted average number of Class A and Class B common shares
outstanding during the period. The basic and diluted loss per common share for
the year ended December 31, 1997 give effect to the issuance of the common stock
of the Company as if the issuance occurred on January 1, 1997.

INCOME TAXES:

     Prior to December 4, 1997, no provision for income taxes was made in the
financial statements as the partners were required to report their respective
share of income or loss on their respective income tax returns. Beginning
December 4, 1997, the Company accounts for income taxes pursuant to the
provisions of SFAS No. 109, "Accounting for Income Taxes." Under SFAS No. 109,
deferred taxes result from temporary differences in the recognition of revenues
and expenses for income tax and financial reporting purposes. At December 31,
1998 and 1997, net deferred tax liabilities represent the tax effect of taxable
temporary differences (pertaining to capitalized costs of approximately $1.3
million) which existed at the date the Partnership converted to a C-Corporation
offset, in part, by accumulated net operating losses of approximately $140,000
in 1998. The Company's net operating losses expire in 2012.

NOTE 2  RELATED PARTIES:


     On October 22, 1998, the Company borrowed $300,000 from certain directors
of the Company. The loans in the amount of $150,000 from Mario J. Gabelli and T.
Gibbs Kane, Jr., bear interest at a rate of 5.00% per year, and become due and
payable on the earlier of (i) October 22, 1999 or (ii) upon the receipt of
proceeds from an offering of rights (the "Rights Offering") to purchase shares
of Class A Common Stock sufficient to pay the full amount of principal and
interest then owed on the notes. The Company plans to offer rights in connection
with such Rights Offering to existing shareholders of the Company's Class A and
Class B Common Stock during 1999 (See Note 8).

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

NOTE 3  PARTNERSHIP AGREEMENT:

     The Partnership was formed in July 1996 to bid for PCS licenses in the
"F-Block" auction. The General Partner originally contributed $100,200 to the
Partnership for a 50.1% equity interest and the Limited Partner contributed
$99,800 to the Partnership for a 49.9% equity interest. Under the terms of the
Partnership Agreement all deductions with respect to interest expense and
commitment fees were allocated 99% to the Limited Partner and 1% to the General
Partner. All profits of the Partnership were allocated 99% to the Limited
Partner and 1% to the General Partner until all the aggregate amount of all
profits allocated to the Limited Partner and General Partner equal the
deductions with respect to interest expense and commitment fees.

     Subsequently, all profits and losses were to be allocated to the Limited
Partner and General Partner in proportion to their respective interests, 49.9%
and 50.1%, respectively. On December 4, 1997, the Partnership was terminated.

NOTE 4  LONG TERM DEBT:

     Long term debt at December 31, 1998 and 1997 consists of FCC financing of
PCS licenses awarded in the following markets and maturing in 2007:

     In connection with the PCS "F-Block" auction, $12.0 million was deposited
with the FCC of which $11.8 million was borrowed from Lynch PCS F under a line
of credit which was due and payable in five years. The interest rate on the
outstanding borrowings under the line was fixed at 15%; additionally, a
commitment fee of 20% per annum was charged on the total line of credit. On
December 4, 1997, the balance of such loan was $7,835,221, including accrued
interest and commitment fees. On such date, $4.5 million was contributed to the
equity of the Partnership and the remaining balance of $3,335,221 was converted
into 7,800 shares of redeemable preferred stock (see note 6). At that time, the
line of credit was terminated.

     All of the FCC financing bears interest at 6.25% per annum. Quarterly
interest payments of $236,972 were required for the first two years of the
license (1997 and 1998) and quarterly payments of principal and interest of
$605,879 are required over the remaining eight years of the license term. These
loans are secured by the licenses granted. In April 1997, the FCC suspended the
interest payments on the debt through March 31, 1998. On March 24, 1998, the FCC
indicated that such interest payments will be resumed not earlier that 90 days
subsequent to publication in the Federal Register of its "Order on
Reconsideration of the Second Report and Order." Such order was published on
April 8, 1998, requiring the suspended payments (aggregating $805,488) to be

if any, the Justice Department or the FCC may take and cannot estimate its
exposure, if any, at this time.

NOTE 1  ACCOUNTING POLICIES:

DESCRIPTION OF BUSINESS:


     East/West Communications, Inc. ("the Company") was incorporated on August
13, 1997, to succeed to the rights and obligations of Aer Force Communications
B, L.P. ("the Partnership"). The Partnership was formed in July 1996, to bid for
personal communications services ("PCS") licenses in the Federal Communications
Commission's ("FCC") F-Block auction. PCS is a second generation digital
wireless service utilizing voice, video or data devices that allow people to
communicate at anytime and virtually anywhere. Over the past three years, the
FCC auctioned off PCS licenses with a total of 120 MHZ of spectrum, falling
within six separate frequency blocks labeled A through F. Frequency blocks C and
F were designated by the FCC as "entrepreneurial blocks." Certain qualifying
small businesses, including the Partnership, were afforded bidding credits in
the auctions as well as government financing of the licenses acquired. The
Partnership won five licenses in 1997 to provide personal communications
services over 10Mhz of spectrum to a population of approximately 21 million,
including Los Angeles and Washington, D.C. Aer Force Communications, Inc. was
the General Partner of the Partnership with a 50.1% equity interest. Lynch PCS
Corporation F ("Lynch PCS F"), a wholly-owned subsidiary of Lynch Corporation
("Lynch"), a publicly held company, was the Limited Partner of the Partnership
with a 49.9% equity interest.


     On December 4, 1997, the Company succeeded to the assets and liabilities of
the Partnership under a plan where the General Partner received 50.1% of the
Common Stock of the Company (in the form of 100% of the Company's Class B Common
Stock) and Lynch PCS F received 49.9% of the Common Stock of the Company (in the
form of 100% of the Company's Class A Common Stock). Just prior to the
succession, the Partners made cash contributions totaling $250,000 (in
proportion to their respective equity interests) to the Partnership and the
Limited Partner contributed $4.5 million of its outstanding loan to the
Partnership's capital.

     Immediately thereafter, Lynch PCS F dividended 39.9% of the Common Stock of
the Company to Lynch which, in turn, dividended this interest to its
shareholders. In addition, Lynch PCS F transferred the remaining 10% of Common
Stock of the Company held by it to Gabelli Funds, Inc., an affiliate of the
Chairman and CEO of Lynch, in satisfaction of a previously incurred obligation.
Also at that time, Lynch PCS F converted the remaining principal amount of its
loan to the Partnership of $3,335,221 (after the capital contribution of
$4,500,000) into a redeemable preferred stock of the Company (see Note 6). Under
the terms of this conversion the Limited Partner's prior obligation to make
further loans to the Partnership was terminated.

BASIS OF PRESENTATION:

     The financial statements are prepared in conformity with generally accepted
accounting principles applicable to a development stage enterprise. The
accompanying unaudited financial statements as of September 30, 1999 and for the
nine month periods ended September 30, 1999 and 1998 have been prepared in
accordance with generally accepted accounting principles applicable to interim
financial information, and in the opinion of management, include all adjustments
(consisting of normal recurring accruals) considered necessary for a fair
presentation.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

NOTE 1  ACCOUNTING POLICIES -- (CONTINUED)
     The Company's financial statements have been prepared on a going concern
basis which contemplates the realization of assets and the satisfaction of
liabilities in the normal course of business and do not include any adjustments
to reflect the possible future effects on the recoverability and classification
of assets and the amount and classification of liabilities that may result from
the possible inability of the Company to continue as a going concern.

     The Company believes that its PCS licenses have substantial potential. As
of September 30, 1999, the Company has not yet adopted a business plan or
determined how to finance its operations because of uncertainties relating to
PCS. However, as explained in Note 9, Subsequent Events, the Company is in the
process of negotiating a merger agreement with Omnipoint Corporation.

     The Company has incurred losses since inception and will need to obtain
capital in order to fund its interest and principal payment obligations and for
working capital and general corporate purposes. There can be no assurance that
the Company can raise sufficient capital to fund its obligations and finance the
construction of its networks. Accordingly, the lack of funding creates
substantial doubt about the Company's ability to continue as a going concern.
The January 1, 1999 interest payment on loan payable to the FCC in the amount of
$388,307 including applicable late fees was paid on July 26, 1999. The April 30,
1999 installment payment in the amount of $388,306 including applicable late
fees was paid on October 25, 1999. The July 31, 1999 payment of $561,373
including principal of $196,983 and interest and late fees of $364,390 was paid
on October 25, 1999.

     Certain prior year amounts have been reclassified to conform to the current
year presentation.

CASH AND CASH EQUIVALENTS:

     Cash and cash equivalents for which the carrying amount approximates fair
value include highly liquid investments with a maturity of three months or less
at the time of purchase.

ADMINISTRATIVE SERVICES:

     The Company and the Partnership has never had any paid employees. Lynch PCS
F provided the Partnership, at its request, with certain services in connection
with the Partnership's bidding for PCS licenses in the FCC auction in late 1996
through early 1997. Aside from that matter, neither the General Partner nor
Lynch PCS F provided the Partnership or the Company with a substantial amount of
services. Neither partner charged the Partnership or the Company for the
services provided, as such amounts are not significant.

USE OF ESTIMATES:

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the carrying amounts of assets and liabilities and
disclosures at the date of the financial statements and the reported amounts of
expenses during the reporting period. Actual results could differ from those
estimates.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

NOTE 1  ACCOUNTING POLICIES -- (CONTINUED)
CAPITALIZED COSTS:

     Interest charges including commitment fees incurred prior to the granting
of the licenses have been expensed. Subsequent to the license grant dates, and
until operations commence, all interest charges (excluding penalty interest and
late fees) and commitment fees on outstanding loan balances will be capitalized.
These costs amounted to $2,897,358 and $1,949,170 at September 30, 1999 and
1998, respectively. Such costs include $2,554,114 and $1,606,231 of capitalized
interest at September 30, 1999 and 1998 respectively. Total interest charges
amounted to $708,964, $708,967, and $3,474,124 for the nine month period ended
September 30, 1999 and 1998 and the period from July 26, 1996 (inception) to
September 30, 1999, respectively.

     The cost of the PCS licenses (including capitalized costs) will be
amortized over a period, consistent with the industry practice, which will begin
when operations commence.

     Pursuant to FCC regulations, license holders are required to commence
providing service to one-third or the population within the license area within
five years from the date of award and two-thirds of the population within ten
years from the date of award. Such licenses may only be transferred to other
entities that meet the FCC requirements for F-Block license holders during the
first five years of the initial license term. Transfers of such licenses to
entities not meeting such requirements in years six through ten of the initial
license term will subject the Company to substantial unjust enrichment
penalties.

LOSS PER SHARE:

     In 1997, the Financial Accounting Standards Board issued SFAS No. 128,
"Earnings per Share," which was adopted by the Company in 1997 upon the issuance
of its common stock. Basic loss per common share is calculated by dividing net
loss by the weighted average number of Class A and Class B common shares
outstanding during the period.

INCOME TAXES:

     Prior to December 4, 1997, no provision for income taxes was made in the
financial statements as the partners were required to report their respective
share of income or loss on their respective income tax returns. Beginning
December 4, 1997, the Company accounts for income taxes pursuant to the
provisions of SFAS No. 109, "Accounting for Income Taxes." Under SFAS No. 109,
deferred taxes result from temporary differences in the recognition of revenues
and expenses for income tax and financial reporting purposes. At September 30,
1999 and 1998, net deferred tax liabilities represent the tax effect of taxable
temporary differences (pertaining to capitalized costs of approximately $1.3
million) which existed at the date the Partnership converted to a C- Corporation
offset, in part, by accumulated net operating losses of approximately $345,000
through the third quarter 1999. The Company's net operating losses expire in
2012.

NOTE 2  RELATED PARTIES:

     On October 22, 1998, the Company borrowed $300,000 from certain directors
of the Company. In order to meet the April 29, 1999 interest payment obligation
to the FCC, the Corporation borrowed

additional funds in the amount of $400,000 from the same directors. The loans in
the amount of $350,000 from Mario J. Gabelli and T. Gibbs Kane, Jr., bear
interest at a rate of 5% per year. The loans were paid in full on June 29, 1999
plus accrued interest in the amount of $12,164.

NOTE 3  PARTNERSHIP AGREEMENT:

     The Partnership was formed in July 1996 to bid for PCS licenses in the
"F-Block" auction. The General Partner originally contributed $100,200 to the
Partnership for a 50.1% equity interest and the Limited Partner contributed
$99,800 to the Partnership for a 49.9% equity interest. Under the terms of the
Partnership Agreement all deductions with respect to interest expense and
commitment fees were allocated 99% to the Limited Partner and 1% to the General
Partner. All profits of the Partnership were allocated 99% to the Limited
Partner and 1% to the General Partner until all the aggregate amount of all
profits allocated to the Limited Partner and General Partner equal the
deductions with respect to interest expense and commitment fees.

     Subsequently, all profits and losses were to be allocated to the Limited
Partner and General Partner in proportion to their respective interests, 49.9%
and 50.1%, respectively. On December 4, 1997, the Partnership was terminated.

NOTE 4  LONG TERM DEBT:


     Long term debt at September 30, 1999 and December 31, 1998 consists of FCC
financing of PCS licenses awarded in the following markets and maturing in 2007:

</TABLE>

     In connection with the PCS "F-Block" auction, $12.0 million was deposited
with the FCC of which $11.8 million was borrowed from Lynch PCS F under a line
of credit which was due and payable in five years. The interest rate on the
outstanding borrowings under the line was fixed at 15%; additionally, a
commitment fee of 20% per annum was charged on the total line of credit. On
December 4, 1997, the balance of such loan was $7,835,221, including accrued
interest and commitment fees. On such date, $4.5 million was contributed to the
equity of the Partnership and the remaining balance of $3,335,221 was converted
into 7,800 shares of redeemable preferred stock (see note 6). At that time, the
line of credit was terminated.

     All of the FCC financing bears interest at 6.25% per annum. Quarterly
interest payments of $236,972 were required for the first two years of the
license (1997 and 1998) and quarterly payments of principle and interest of
$605,879 are required over the remaining eight years of the license term. These

loans are secured by the licenses granted. In April 1997, the FCC suspended the
interest payments on the debt through March 31, 1998. On March 24, 1998, the FCC
indicated that such interest payments will be resumed not earlier that 90 days
subsequent to publication in the Federal Register of its "Order on
Reconsideration of the Second Report and Order." Such order was published on
April 8, 1998, requiring the suspended payments (aggregating $805,488) to be
made in eight quarterly installments of $100,686 beginning in July 1998, plus
regular interest payments for the period of March 31, 1998 to July 31, 1998, of
$311,324, subject to deferral of up to a maximum 180 days. Payment was made on
October 28, 1998, within the 90-day non-delinquency period, in the amount of
$432,610 comprising accrued interest of $412,010 and a 5% penalty fee of
$20,600.

     The interest on the loan payable to the FCC, due on October 31, 1998
amounted to $340,249. Payments made within 90 days of the due date are subject
to a 5% penalty which increases to a 15% penalty if paid within 90 to 180 days
of the due date. The Company issued the required payment of $391,286 (including
applicable penalties) on April 26,1999. The payment of interest due on 1/31/99
in the amount of $388,307 including applicable late fees was paid on July 26,
1999. The payment due on April 30, 1999 in the amount of $388,306 including
applicable late fees was paid on October 25, 1999 and the payment due on July
31, 1999 in the amount of $561,373 including principal of $196,983 plus interest
and late fees of $364,090 was paid on October 25, 1999.

     Aggregate principle maturities of long-term debt for each of the next five
years are as follows: 1999 -- $.744 million, 2000 -- $1.558 million,
2001 -- $1.658 million, 2002 -- $1.764 million and 2003 --  $1.877 million.

NOTE 5  COMMON STOCK:

     The Company has two classes of Common Stock authorized: Class A Common
Stock and Class B Common Stock. The authorized capital stock of the Company
consists of 16,000,000 shares of Class A Common Stock and 3,600,000 shares of
Class B Common Stock.

     The holders of Common Stock are entitled to receive ratably such dividends,
if any, as may be declared from time to time by the Board of Directors out of
funds legally available therefor. In the event of the liquidation, dissolution
or winding up of the Company, the holders of Common Stock are entitled to share
ratably in all assets remaining after payment of liabilities, if any, then
outstanding. Collectively, the shares of Class A Common Stock represent not more
than 49.9% of the Company's voting interest, with each share of Class A Common
Stock issued and outstanding having one vote per share on all matters, except
the election of directors or as otherwise provided by law. The holders of the
Class A Common Stock as a class will be entitled to elect members to the
Company's Board of Directors who collectively will represent two of the five
votes of the Company's Board of Directors.

     Collectively, the shares of Class B Common Stock represent at least 50.1%
of the Company's voting interest, with each shares of Class B Common Stock
issued and outstanding having 5 votes per share on all matters, except the
election of directors or as otherwise provided by law. With respect to the
election of directors, the Class B Common Stock, voting together as a class, may

NOTE 6  REDEEMABLE PREFERRED STOCK:


     The Company is authorized to issue 16,000 shares of Preferred Stock and at
September 30, 1999 and 1998 had outstanding 7,800 shares of Preferred Stock, par
value $1,000 per share. The Preferred Stock (i) is entitled to preferred
dividends at an annual rate of five (5) shares of additional Preferred Stock for

amortized using the effective interest method to November 1, 2009. Accrued
dividends and accretion on the preferred stock are included in the preferred
stock account in the balance sheets and the dividend requirement on preferred
stock in the statements of operations.


NOTE 7  LEGAL MATTERS:

     The United States Department of Justice initiated an investigation during
1997 to determine whether there had been bid rigging and market allocation for
licenses auctioned by the FCC for PCS. The Company, together with various other
bidders in the PCS auctions, had received a civil investigative demand ("CID")
requesting documents and information relating to bidding, and in May 1997, the
Company complied with the CID. The Company is not aware of what further action,
if any, the Justice Department or the FCC may take and cannot estimate its
exposure, if any, at this time.

NOTE 8  RIGHTS OFFERING:

     The Company offered, at no cost to the holders of its Class A Common Stock,
a non-transferable right to purchase up to 443,050 shares of Class A Common
Stock. The rights entitle shareholders to purchase one additional share of Class
A Common Stock for every four shares of Class A Common Stock held at a price of
$1.50 per share. In addition, shareholders were provided on oversubscription
privilege to acquire shares not initially purchased pursuant to the Rights. The
Company also offered rights to purchase 444,825 shares of Class B Common Stock
at a price of $1.50 per share to the current owners of the Company's Class B
Common Stock. The Class A and Class B shareholders exercised these rights on
June 23, 1999.


NOTE 9  SUBSEQUENT EVENTS:



     On October 22, 1999, East/West Communications, Inc. and Omnipoint
Corporation entered into an Agreement and Plan of Merger (the "East/West Merger
Agreement"), pursuant to which, among other things, East/West will merge with
and into Omnipoint (the "East/West Merger") which will be the surviving
corporation in the East/West Merger.



     Omnipoint is also party to an Agreement and Plan of Reorganization (the
"VoiceStream Merger Agreement") dated as of June 23, 1999, by and among
Omnipoint, VoiceStream Wireless Corporation, and VoiceStream Wireless Holding
Corporation ("VoiceStream Holdings") pursuant to which Omnipoint will be merged
with a newly formed, wholly-owned subsidiary of VoiceStream Holdings (the
"VoiceStream Reorganization"), and each share of common stock of Omnipoint will
be converted into

the right to receive .825 shares of common stock of VoiceStream Holdings and
$8.00 in cash, subject to the right of the holders of outstanding shares of
Omnipoint common stock to elect to receive stock and cash consideration in
different proportions.


     It is anticipated that the East/West Merger will be consummated immediately
prior to the VoiceStream Reorganization. Under the terms and conditions of the
East/West Merger Agreement, if the East/West Merger is consummated prior to the
VoiceStream Reorganization, (i) in the East/West Merger, each outstanding share
of Class A Common Stock and Class B Common Stock of the Company (collectively,
the "East/West Common Stock") will be converted into one share of newly
authorized Series E Preferred Stock of Omnipoint (the "Series E Preferred
Stock") and (ii) each share of Series E Preferred Stock received by the holders
of East/West Common Stock in the East/West Merger will be converted in the
VoiceStream Reorganization into (x) .825 shares of common stock of VoiceStream
Holdings and $8.00 in cash (the "Standard Election Consideration"), multiplied
by (y) a conversion ratio (the "Conversion Ratio") equal to 1,775,000 divided by
the number of shares of East/West Common Stock outstanding immediately prior to
consummation of the East/West Merger. Currently, there are 4,839,374 shares of
East/West Common Stock issued and outstanding.



     Under the terms of the East/West Merger Agreement, if the VoiceStream
Reorganization occurs prior to the consummation of the East/West Merger, each
share of East/West Common Stock will be converted into the right to receive (x)
the Standard Election Consideration, multiplied by (y) the Conversion Ratio. If
the VoiceStream Merger Agreement is terminated prior to the consummation of the
East/West Merger, each share of East/West Common Stock will be converted in the
East/West Merger into (x) one share of Omnipoint Common Stock, multiplied by (y)
the Conversion Ratio. Under the terms and conditions of the East/West Merger
Agreement, each outstanding share of preferred stock of the Company will be
converted into the right to receive in all events cash in the amount of $1,000
per share, plus accrued dividends.



     Concurrently with the execution of the East/West Merger Agreement,
East/West and Omnipoint entered into a Securities Purchase Agreement (the
"Securities Purchase Agreement"), dated as of October 22, 1999, pursuant to
which Omnipoint bought from East/West, and East/West issued to Omnipoint,
300,000 shares of Class A Common Stock of East/West for the purchase price of
$3,000,000. $150,000 of the proceeds of the Omnipoint stock purchase will be
held in escrow by Omnipoint and will be paid as a fee to Gabelli & Company, Inc.
(an affiliate of Mario Gabelli, a director of East/West) if the Merger does not
close. If and when the Merger closes, those funds will be retained by Omnipoint,
which will then issue Gabelli & Company, Inc. 25,000 shares of Omnipoint Series
E Preferred Stock. Approximately $1.7 million of the proceeds of the Omnipoint
stock purchase were used to repay all past and currently due interest and
principal payments, including penalties, on the company's obligations to the
FCC.


     Pursuant to the terms and conditions of the Securities Purchase Agreement,
East/West granted to Omnipoint a right of first refusal with respect to the
sale, exchange or other disposition of the PCS licenses held by East/West.
Omnipoint's right of first refusal will be in effect for a period of two years
after any termination of the Omnipoint Merger Agreement.

SECTION 2.1  The Merger.

     Upon the terms and subject to the conditions set forth in this Agreement:

          (a) The Company shall merge with and into Omnipoint (with such merger
     referred to herein as the "Merger") at the Effective Time in accordance
     with the applicable provisions of Delaware Law. Following the Effective
     Time, the separate existence of the Company shall cease, and Omnipoint
     shall continue as the surviving corporation of the Merger (the "Surviving
     Corporation"). The effects and consequences of the Merger shall be as set
     forth in this Agreement, the Certificate of Merger, and under the
     applicable provisions of Delaware law. Without limiting the generality of
     the foregoing, and subject thereto, at the Effective Time, all the
     property, rights, privileges, powers and franchises of the Company and
     Omnipoint shall vest in the Surviving Corporation, and all debts,
     liabilities and duties of the Company and Omnipoint shall become the debts,
     liabilities and duties of the Surviving Corporation.

          (b) Subject to the terms and conditions of this Agreement and the last
     sentence of this paragraph, the closing of the Transactions (the "Closing")
     shall take place at the offices of Piper & Marbury, 1200 Nineteenth Street,
     N.W., Washington, DC 20036, commencing at 10:00 a.m., local time, on the

     VoiceStream Merger Agreement has been terminated prior to satisfaction or
     waiver of the conditions set forth in Article 9 (excluding conditions, that

     (5th) Business Day following the date on which the last of the conditions
     set forth in Article 9
                                      A-12
<PAGE>   116

     is satisfied or waived (excluding conditions that, by their terms, cannot
     be satisfied until the Closing Date, but subject to the fulfillment or
     waiver of such conditions) and (ii) in the event that the conditions in
     Article 9 have been satisfied or waived prior to the termination of the
     VoiceStream Merger Agreement, the date that is the earliest of: (A) the
     date of the closing of the VoiceStream Merger (the "VoiceStream Merger
     Closing Date"), provided, that all of the conditions set forth in Article 9
     have been satisfied or waived (excluding conditions that, by their terms,
     cannot be satisfied until the Closing Date, but subject to the fulfillment
     or waiver of such conditions); (B) the first date after the VoiceStream
     Merger Closing Date on which all of the conditions set forth in Article 9
     have been satisfied or waived (excluding conditions that, by their terms,
     cannot be satisfied until the Closing Date, but subject to the fulfillment
     or waiver of such conditions); and (C) the fifth (5th) Business Day after
     the first date following the date that the VoiceStream Merger Agreement has
     been terminated on which the conditions set forth in Article 9 have been
     satisfied or waived (excluding conditions that, by their terms, cannot be
     satisfied until the Closing Date, but subject to the fulfillment or waiver
     of such conditions). The Closing shall take place immediately prior to, and
     as part of the same plan as, the consummation of the VoiceStream Merger,
     unless (i) the VoiceStream Merger Agreement has been terminated or (ii)
     Section 11.1(b) applies.

          (c) Subject to the terms and conditions of this Agreement, as soon as
     practicable following the Closing, the Parties shall, as applicable: (1)
     file a certificate of merger with respect to the Merger (the "Certificate
     of Merger") in such form as is reasonably acceptable to each Party and
     otherwise required by and executed in accordance with applicable Delaware
     Law and (2) make all other filings or recordings required under applicable
     Delaware Law. The Merger shall become effective at such time and date (the
     "Effective Time") which is the date and time that the Certificate of Merger
     is duly filed with the Secretary of State of the State of Delaware, or such
     other date and time as the Company and Omnipoint shall agree should be
     specified in the Certificate of Merger and as may be permitted by Delaware
     Law.

shall be the directors of the Surviving Corporation as of the Effective Time and
until their successors are duly appointed or elected in accordance with
applicable Delaware Law.

                                   ARTICLE 3
                EFFECT OF THE MERGER ON SECURITIES OF OMNIPOINT
                                AND THE COMPANY

     Subject to Article 11 hereof:

SECTION 3.1  Company Capital Stock.

     At the Effective Time, by virtue of the Merger and without any action on
the part of any holder of any shares of Company Common Stock or Company
Preferred Stock or any holder of shares of capital stock of Omnipoint or the
Parties: (1) subject to Section 3.2, each share of Company Common Stock
(excluding any Dissenting Shares or shares of the Company Common Stock held by
Omnipoint) that is issued and outstanding immediately prior to the Effective
Time shall be converted into the right to receive one share of Series E
Preferred Stock (collectively, the "Merger Shares"); (2) each Dissenting Share
shall be converted into the right to receive payment from the Surviving
Corporation with respect thereto in accordance with Delaware Law; and (3) each
share of Company Preferred Stock that is issued and outstanding immediately
prior to the Effective Time (after giving effect to any redemption of Preferred
Stock contemplated by Section 6.2(b)(2) and Section 1.3 of the Securities
Purchase Agreement) shall be converted into the right to receive the Per Share
Exchange Amount (as defined). The term "Per Share Exchange Amount" shall mean
the Liquidation Value (as defined) of each share of Company Preferred Stock plus
all accrued and unpaid dividends thereon, and the term "Exchange Amount" shall
mean the total of all Per Share Exchange Amounts in the aggregate. The term
"Liquidation Value" shall mean $1,000 per share of Company Preferred Stock. The
Exchange Amount, together with the Merger Shares, is collectively referred to
herein as the "Merger Consideration." At the Effective Time, all such shares of
Company Common Stock and Company Preferred Stock shall be automatically canceled
and retired and cease to exist, and each holder of a Certificate or Certificates
representing any such shares shall cease to have any rights with respect
thereto, except the right to receive the Merger Consideration upon surrender of
such certificates in accordance with this Agreement. Upon such conversion, the
Company Common Stock issued to Omnipoint and outstanding immediately prior to
the Effective Time shall be automatically canceled and retired and cease to
exist. The term "Conversion Ratio" shall mean a fraction, the numerator of which
shall be 1,775,000 and the denominator of which shall be the number of shares of
Company Common Stock issued and outstanding, immediately prior to the Effective
Time.

SECTION 3.2  Adjustments.

     If between the date of this Agreement and the Effective Time the
outstanding shares of Omnipoint Common Stock shall have been changed into a
different number of shares, by reason of any stock dividend, subdivision, split
or combination of shares (each, a "Recapitalization Event"), the numerator of
the Conversion Ratio will be correspondingly adjusted to reflect such
Recapitalization Event. Between the date of this Agreement and the Effective
Time, the Company covenants and agrees not to effect or take any action with
respect to a Recapitalization Event with respect to shares of Company Common
Stock or Company Preferred Stock.

SECTION 3.3  Surrender and Payment.

     (a) Prior to the Effective Time, Omnipoint shall appoint an agent
reasonably acceptable to the Company (the "Exchange Agent") for the purpose of
exchanging in accordance with Section 3.3(b), a certificate or certificates (the
"Certificates") that, immediately prior to the Effective Time, represented
issued and outstanding shares of Company Common Stock and Company Preferred
Stock which were converted into the right to receive the applicable Merger
Consideration pursuant to Section 3.1. At the Effective Time, Omnipoint will
deposit (or cause to be deposited) with the Exchange Agent the Merger

                                      A-14
<PAGE>   118

Consideration to be exchanged in respect of such shares (the "Exchange Fund").
Promptly after the Effective Time, Omnipoint will send, or will cause the
Exchange Agent to send to each holder of record of shares of Company Common
Stock and Company Preferred Stock at the Effective Time (the "Holders"), 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.

     (b) Subject to Section 3.5, upon surrender to the Exchange Agent of its
Certificate or Certificates for cancellation, together with a properly completed
letter of transmittal, duly executed, and such other documents as may be
reasonably required by the Exchange Agent, the Holder of such Certificate or
Certificates will be entitled to receive promptly after the Effective Time, the
Merger Consideration in accordance with this Agreement. Until so surrendered,
each such Certificate shall represent after the Effective Time, for all
purposes, only the right to receive the appropriate Merger Consideration in
accordance with this Agreement.

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

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

     (e) Any portion of the Exchange Fund made available to the Exchange Agent
pursuant to Section 3.3(a) that remains unclaimed by the Holders one year after
the Effective Time shall be returned to Omnipoint, upon demand, and any such
Holder who has not exchanged its shares for the Merger Consideration in
accordance with this Section 3.3 prior to that time shall thereafter look only
to Omnipoint for payment of such consideration, any dividends and distributions
in respect of such shares, in each case without any interest thereon.
Notwithstanding the foregoing, Omnipoint shall not be liable to any Holder for
any amounts paid to a public official pursuant to applicable abandoned property,
escheat or similar laws. Any amounts remaining unclaimed by the 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 Omnipoint free and clear of any claims or interest of any Person
previously entitled thereto.

     (f) No dividends or other distributions with respect to any Merger Shares
shall be paid to the Holder of any unsurrendered Certificates until such
Certificates are surrendered as provided in Section 3.3. Following such
surrender, there shall be paid, without interest, to the Person in whose name
such Merger Shares have been registered, (1) at the time of such surrender, 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 Merger Shares, and (2) 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 Merger Shares.

     (g) Any portion of the Merger Consideration made available to the Exchange
Agent pursuant to Section 3.3(a) to pay for shares for which appraisal rights
have been perfected shall be returned to Omnipoint upon demand.

                                      A-15
<PAGE>   119

     (h) All Merger Consideration issued upon the surrender for exchange of
shares of Company Common Stock or Company Preferred Stock, as the case may be,
in accordance with the terms hereof shall be deemed to have been issued in full
satisfaction of all rights pertaining to such shares of Company Common Stock or
Company Preferred Stock.

SECTION 3.4  Exchange Agent Instructions.

     At the Effective Time, Omnipoint shall instruct the Exchange Agent to (i)
issue the certificates representing the Merger Shares to the Holders of
Certificates that, immediately prior to the Effective Time, represented issued
and outstanding shares of Company Common Stock and (ii) pay the Exchange Amount
to the Holders of Certificates that, immediately prior to the Effective time,
represented issued and outstanding shares of Company Preferred Stock; in each
case, in accordance with the terms and conditions of this Article 3.

SECTION 3.5  Dissenting Shares.

     Notwithstanding Section 3.1, Company Common Stock issued and outstanding
immediately prior to the Effective Time and held by a Holder who has not voted
in favor of the Merger or consented thereto in writing and who has demanded
appraisal for such shares in accordance with Section 262 of Delaware Law, if
such Section 262 provides for appraisal rights for such shares in the Merger
("Dissenting Shares") shall not be converted into a right to receive the Merger
Shares unless and until such holder fails to perfect, withdraws or otherwise
loses its right to appraisal and payment under Delaware Law. If, after the
Effective Time, any such Holder fails to perfect, withdraws or loses its right
to appraisal, such Dissenting Shares shall be treated as if they had been
converted as of the Effective Time into the right to receive the Merger Shares,
if any, to which such Holder is entitled, without interest or dividends thereon.
The Company shall give Omnipoint prompt notice of any demands received by the
Company for appraisal of shares of Company Common Stock, and Omnipoint shall
have the right to participate in all negotiations and proceedings with respect
to such demands. Except with the prior written consent of Omnipoint, the Company
shall not make any payment with respect to, or settle or offer to settle, any
such demands.

SECTION 3.6  Withholding Rights.

     Omnipoint and the Company (to the extent it uses its funds to redeem the
Company Preferred Stock) 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 applicable provision of federal, state, local or foreign
tax law. If Omnipoint so withholds amounts, such amounts shall be treated for
all purposes of this Agreement as having been paid to such Person, as the case
may be, in respect of which Omnipoint made such deduction and withholding.

SECTION 3.7  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
Omnipoint (and, if required by Omnipoint 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 Omnipoint may direct, as indemnity) indemnifying
Omnipoint against any claim that may be made against Omnipoint, the Surviving
Corporation or the Exchange Agent with respect to the Certificate alleged to
have been lost, stolen or destroyed, the Exchange Agent will issue, in exchange
for such lost, stolen or destroyed Certificate, the Merger Consideration to be
paid in respect of the shares represented by such Certificate in accordance with
this Agreement.

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

     Except as otherwise disclosed in the Company SEC Documents filed with the
SEC prior to the date hereof, the Company represents and warrants to Omnipoint
as follows:

SECTION 4.1  Corporate Existence and Power.

     The Company is a corporation 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. The Company is duly
qualified to do business as a foreign corporation and is in good standing in
each jurisdiction where such qualification is necessary, except for those
jurisdictions where failure to be so qualified, individually or in the
aggregate, has not had and would not be reasonably expected to have a Company
Material Adverse Effect. The Company has heretofore delivered or made available
to Omnipoint true and complete copies of the certificate of incorporation and
bylaws of the Company as currently in effect.

SECTION 4.2  Corporate Authorization.

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

     (b) At a meeting duly called and held, the Company's Board of Directors
has: (1) determined that this Agreement and the Transactions are advisable and
fair to and in the best interests of the Company's stockholders; (2) approved
and adopted this Agreement and the Transactions; and (3) resolved (subject to
Section 8.7(b)) to recommend approval and adoption of this Agreement by its
stockholders. No other corporate proceedings on the part of the Company 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
Company Common Stock to the extent required by the Company's certificate of
incorporation and by applicable Delaware Law).

SECTION 4.3  Governmental Authorization.

     (a) The execution, delivery and performance by the Company of this
Agreement and the consummation by the Company of the Transactions require no
action by or in respect of, or filing with, any Governmental Body, other than:
(1) the filing of the Certificate of Merger in accordance with Delaware Law; (2)
compliance with any applicable requirements of the HSR Act; (3) compliance with
any applicable requirements of the 1934 Act; (4) compliance with any applicable
requirements of the Communications Act; (5) compliance with FAA regulations; (6)
compliance with any applicable requirements of state and local public utility
commissions or similar entities; and (7) 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 the Company from
performing its obligations under this Agreement in any material respect or would
not in the aggregate have a Company Material Adverse Effect.

                                      A-17
<PAGE>   121

     (b) The Company has 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) The Company holds, and is qualified and eligible to hold, all licenses,
permits and other authorizations issued by the FCC, that are listed in Schedule
4.4A of the Company Disclosure Schedules (the "Company FCC Licenses"), and the
Company FCC Licenses comprise all licenses, permits and other authorizations
issued to the Company by the FCC. The Company has no applications for a license,
permit, or other authorization or for approval or consent pending before the
FCC.

     (b) The Company FCC Licenses are valid and in full force and effect and
except as set forth in Schedule 4.4B of the Company Disclosure Schedules, the
Company is not and has not been delinquent in payment on or in default under any
installment obligation owed to the United States Treasury or the FCC in
connection with the Company FCC Licenses.

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

     (d) The Company is, and has been, in compliance in all material respects
with the Company FCC Licenses and 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 Company which
questions the validity of or contests any Company FCC License or which, 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 Company FCC License or imposition of any substantial
fine or forfeiture against the Company.

SECTION 4.5  Non-contravention.

     The execution, delivery and performance by the Company of this Agreement
and the consummation by the Company of the Transactions do not and will not: (i)

SECTION 6.2  Equity Issuances by the Company.

     (a) Notwithstanding any provision of this Agreement to the contrary, except

limitation, Section 6.1 hereof) shall limit the right or ability of the Company,
between the date hereof and the Closing (i) to issue any shares of capital stock
(including shares of Company Common Stock or any options, warrants or other
rights exercisable for shares of capital stock of the Company) ("Additional
Company Capital Stock") that provide by the terms of such Additional Company
Capital Stock for the automatic conversion of such shares of Additional Company
Capital Stock (other than Company Common Stock) into shares of Company Common
Stock immediately prior to the Effective Time; provided, that, the consideration
received by the Company in respect of the issuance of such Additional Company
Capital Stock, after giving effect to the automatic conversion of such shares of
capital stock into shares of Company Common Stock, is equal to a price per share
of at least $10.00 (each such issuance, an "Issuance"), and (ii) to amend its
certificate of incorporation to the extent necessary to permit the issuance of
Additional Company Capital Stock of the Company permitted by the foregoing
clause (i); provided, that, with respect to the foregoing clause (i) -- (ii):
(1) the Additional Company Capital Stock to be issued pursuant to an Issuance
shall not have any designations, powers, preferences and relative and other
special rights that would permit such Additional Company Capital Stock of the
Company to control the Company or to cause the Company to take any actions set
forth in Section 6.1(a)-(u); (2) the Company shall not take any actions in
issuing Additional Company Capital Stock that would materially delay or impair
the consummation of the Transactions; (3) the total aggregate amount of the
gross proceeds of any such Issuances shall not exceed $20,000,000; (4) the
Company shall not consummate any Issuance that would result in (a) the Company's
ineligibility to hold the Company FCC Licenses or (b) in the Company having the
right to redeem (other than pursuant to the terms of the Additional Company
Capital Stock issued pursuant to such Issuance) any shares of Company Common
Stock or shares of Additional Company Common Stock held by Omnipoint as a result
of Omnipoint's exercise of the Preemptive Right in connection with such
Issuance; (5) the Company shall not take any actions that would result in
AerForce Communications, Inc., owning securities of the Company representing
less than 50.1% of the voting power of the Company's equity securities on a
Fully-Diluted Basis (as defined); and (6) each purchaser of such shares shall,
at the time, execute and deliver to Omnipoint the Voting Agreement; and (7) the
Company shall comply with paragraphs (b) and (c) below.

     (b) Preemptive Right. Subject to the terms and conditions specified in this
paragraph (b), the Company hereby grants to Omnipoint a preemptive right to
purchase its pro rata portion of any shares of Additional Company Capital Stock
that the Company issues pursuant to any Issuance in accordance with the
following provision (the "Preemptive Right").

          (1) The Company shall give to Omnipoint written notice by certified
     mail (the "Preemptive Right Notice") of any proposed Issuance of Additional
     Company Capital Stock no later than the time such offer is made to other
     offerees (the "Offer Date"). Omnipoint shall have fifteen (15) days from
     the closing of any such Issuance to agree to purchase up to its pro rata
     portion of such shares of Additional Company Capital Stock issued pursuant
     to such Issuance for the price and on the terms and conditions as any other
     purchaser of such shares by giving written notice to the Company and
     stating therein the quantity of shares (up to a maximum of its pro rata
     portion) to

                                      A-33
<PAGE>   137

     be purchased. The Company agrees to sell and issue to Omnipoint such shares
     of Additional Company Capital Stock that Omnipoint elects to purchase on
     the same terms and conditions as any other purchaser of such shares. For
     purposes of the Preemptive Right, Omnipoint's pro rata portion of shares of
     Additional Company Capital Stock issued pursuant to any Issuance is equal
     to the number of shares of such Additional Company Capital Stock that, when
     added to the number of shares of Company Common Stock issued or issuable to
     Omnipoint on a Fully-Diluted Basis prior to such Issuance would result in
     the Omnipoint Post-Issuance Percentage Interest being equal to the
     Omnipoint Pre-Issuance Percentage Interest. "Omnipoint Pre-Issuance
     Percentage Interest" means, with respect to any Issuance, the fraction
     equal to the number of shares of Company Common Stock issued or issuable to
     Omnipoint on a Fully-Diluted Basis immediately prior to such Issuance,
     divided by the total number of shares of Company Common Stock on a
     Fully-Diluted Basis outstanding immediately prior to such Issuance.
     "Omnipoint Post-Issuance Percentage Interest" means with respect to any
     Issuance, the fraction equal to the number of shares of Company Common
     Stock issued or issuable to Omnipoint on a Fully-Diluted Basis immediately
     after such Issuance, divided by the total number of shares of Company
     Common Stock on a Fully-Diluted Basis outstanding immediately after such
     Issuance. "Fully-Diluted Basis" gives effect, without duplication, to all
     shares of Company Common Stock outstanding at the time of determination
     plus all shares of Company Common Stock issuable as if all Additional
     Company Common Stock had been converted or exercised (in the case of
     options, warrants or other rights exercisable for shares of Company Common
     Stock), including the effect of any Recapitalization Event.

          (2) In the event Omnipoint exercises the Preemptive Right and
     purchases up to its pro rata portion of the shares of Additional Company
     Capital Stock (such purchased shares, the "Purchased Shares"), the Company
     agrees to use immediately prior to the Effective Time the aggregate gross
     proceeds of the sale of such Purchased Shares (1) to redeem shares of
     Company Preferred Stock at the Per Share Exchange Amount, or (2) to repay
     the principal and interest on loans from the Federal Communications
     Commission relating to the Company FCC Licenses, unless, in each case, the
     Company or Omnipoint should determine that such payment would result in
     Omnipoint acquiring less than ninety percent (90%) of the fair market value
     of the Company's "net assets" and less than seventy percent (70%) of the
     fair market value of the Company's "gross assets", measured for this
     purpose, immediately prior to the Effective Time. For purposes of
     determining the percentage of the Company's "net assets" and "gross assets"
     to be acquired by Omnipoint, the following assets will be treated as held
     by the Company immediately prior to, but not acquired by Omnipoint pursuant
     to the Merger: (i) assets disposed of by the Company prior to the Merger
     and in contemplation thereof (including, without limitation, any assets
     disposed of by the Company, other than in the ordinary course of business,
     pursuant to a plan or intention existing during the period ending on the
     Closing Date and beginning with the commencement of negotiations (whether
     formal or informal) with Omnipoint regarding the Merger); (ii) assets used
     by the Company to pay the Company's stockholders, if any, who perfect
     dissenters' rights; (iii) assets used by the Company to pay reorganization
     expenses or other liabilities incurred in connection with the Merger; and
     (iv) assets used to make distributions, redemptions or other payments
     (except for regular, normal distributions) in respect of the capital stock
     of the Company (including payments treated as such for tax purposes) that
     are made prior to the Merger and are part of the plan of the Merger.

     (c) The Company hereby agrees that with respect to any Issuance, (i) the
shares of Additional Company Capital Stock to be issued pursuant to and in
accordance with this Section 6.2 shall, when issued, sold and delivered, will be
duly and validly issued, fully-paid and nonassessable and shall be issued in
compliance with the registration requirements of all applicable federal and
state securities laws and (ii) the Company shall not provide any information, as
may be amended and supplemented ("Offering Information") to any offeree that
shall 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

                                      A-34
<PAGE>   138

of the circumstances under which they were made, not misleading. The Company
shall provide Omnipoint with copies of all Offering Information to be
distributed in any Issuance on or prior to the Offer Date and shall pay all fees
and expenses related to such Issuance, including, without limitation,
preparation and distribution of the Offering Information.

SECTION 6.3  No Solicitation.

     (a) From the date hereof until the termination hereof, the Company will

indirectly: (1) take any action to knowingly solicit, initiate, facilitate or
encourage the submission of any Acquisition Proposal; (2) engage in any

Agreement shall prevent the Board of Directors of the Company from complying
with Rule 14e-2 and Rule 14d-9 under the 1934 Act with regard to an Acquisition
Proposal; provided that the Board of Directors of the Company shall not
recommend that the stockholders of the Company tender their shares in connection
with a tender offer except to the extent the Board of Directors of the Company
by a majority vote determines in its good faith judgment that such a
recommendation is required to comply with the fiduciary duties of the Board of
Directors of the Company to shareholders under applicable Delaware Law, after
receiving the advice of outside legal counsel.

     (b) The Company will notify Omnipoint promptly (but in no event later than
24 hours) after receipt by the Company (or any of its representatives or
advisors) of any Acquisition Proposal, or of any request for non-public
information relating to the Company or for access to the properties, books or
records of the Company by any Person who is known to be considering making, or
has made, an Acquisition Proposal. The Company shall provide such notice orally
and in writing and shall identify the Person making, and the terms and
conditions of, any such Acquisition Proposal, indication or request. The Company

SECTION 6.4  Access to Information.

financial and operating data and all information concerning all capital
expenditures and other information to which the Company's Board of Directors or
the officers of the Company are provided or have access to (all of the foregoing
to be furnished to Omnipoint simultaneously with the same being furnished to any
member of the Company's Board of Directors or officers of the Company); and
(iii) instruct its counsel, financial advisors, auditors and other authorized
representatives to cooperate with Omnipoint (and its representatives and agents)
in its investigation. Any investigation pursuant to this Section 6.4 shall be
conducted in such manner as not to interfere unreasonably with the conduct of

SECTION 6.5  Confidentiality.

     Except as contemplated hereby, none of the parties hereto shall (or permit
its Representatives (as defined) to), directly or indirectly, disclose any
information received from the another Party or its Representatives (as defined)
in connection with the Transactions, including without limitation, information
received during a Party's due diligence investigation (such party receiving such
information, the "Receiving Party" and such party disclosing such information,
the "Disclosing Party"); except as required by law or judicial or administrative
processes. Information will not be subject to the provisions of this Section 6.5
which (i) is or becomes publicly available other than as a result of a breach by
the Receiving Party; (ii) is or becomes available on a non-confidential basis
from a source which is not prohibited by contract or law from disclosing such
information to the Receiving Party; or (iii) was known by the Receiving Party
prior to the disclosure thereof by the Disclosing Party other than by means that
would be a violation of this Section 6.5 had it been in effect at the time of
disclosure. As used herein, the term "Representatives" refers a Party's
directors, officers, employees, affiliates, representatives or agents. The
Parties acknowledge and agree that any breach of this Section 6.5 by a Party
would cause irreparable harm to the other party hereto and that, in such event,
such other party shall have the right, among other things, to preliminary and
injunctive relief, in addition to any other relief to which such other party may
be entitled. In the event that the Transactions are not consummated, the
Receiving Party shall promptly return all such written information provided by
the Disclosing Party or its Representatives and destroy any copies or notes
derived therefrom.

SECTION 6.6  Payment of Company Fees.

     (a) Prior to or simultaneously with the execution of this Agreement, the
Company shall place in escrow the Finders' Fees described in Section 4.14 hereof
(such amount together with all interest thereon, collectively the "Escrow

the Escrow Fund shall be released to Gabelli. In the event that the Transactions
have been consummated, at the Closing, the Escrow Fund shall be released to
Omnipoint.

     (b) At the Closing, Omnipoint shall issue to Gabelli on behalf of the
Company 25,000 shares of Series E Preferred Stock (the "Fee Shares") in
satisfaction of the Company's liability with respect to the Company Fees.

SECTION 7.1  Director and Officer Liability.

     (a) Omnipoint shall indemnify and hold harmless and advance expenses to the
present and former officers and directors of the Company and each person who
prior to the Effective Time becomes an officer or director of the Company (each
an "Indemnified Person"), in respect of acts or omissions by them in their
capacities as such occurring at or prior to the Effective Time (including,
without limitation, for acts or omissions occurring in connection with this
Agreement and the consummation of the Transactions) to the same extent provided
under the Company's certificate of incorporation and bylaws in effect on the
date hereof (collectively, the "Indemnified Losses"); provided that such
indemnification shall be subject to any limitation imposed from time to time
under applicable law. Without limiting the generality of the foregoing, the
Indemnified Losses shall include reasonable costs of prosecuting a claim under
this Section 7.1a). Omnipoint shall periodically advance or reimburse each
Indemnified Person for all reasonable fees and expenses of counsel constituting
Indemnified Losses as such fees and expenses are incurred; provided that such
Indemnified Person shall agree to promptly repay to Omnipoint the amount of any
such reimbursement if it shall be judicially determined by judgment or order not
subject

                                      A-36
<PAGE>   140

to further appeal or discretionary review that such Indemnified Person is not
entitled to be indemnified by Omnipoint in connection with such matter.

     (b) The rights of each Indemnified Person and its heirs and legal
representatives under this Section 7.1 shall be in addition to any rights such
Person may have under the certificate of incorporation or bylaws of the Company,
or under Delaware Law or any other applicable laws. These rights shall survive
consummation of the Transactions and are intended to benefit, and shall be
enforceable by, each Indemnified Person.

SECTION 7.2  Certificate of Designations for Series E Preferred Stock.

     As soon as practicable after the date hereof, Omnipoint shall adopt and
file with the Secretary of State of the State of Delaware the Certificate of
Designation establishing the designations, powers, preferences, limitations,
restrictions and relative rights of the Series E Preferred Stock, substantially
in the form attached hereto as Exhibit A (the "Certificate of Designation").
Between the date hereof and the earliest of: (i) the Effective Time; (ii) the
termination of this Agreement; or the time when Section 11.1(b) applies,
Omnipoint shall not amend or modify the Certificate of Designation without the
prior consent of the Company.

                                   ARTICLE 8
                            COVENANTS OF THE PARTIES

     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 (1) 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 (2) 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; provided, however, that no member of the Omnipoint Group or its
Affiliates shall be required to divest or hold separate any assets or otherwise
take or commit to take any action that limits, in any material respect, its
freedom of action with respect to any member of the Omnipoint Group or any
Omnipoint Investment or any material portion of the assets of the Company or
assets of the Omnipoint Group. Subject to applicable laws relating to the
exchange of information, Omnipoint and the Company shall have the right to
review in advance, and to the extent practicable to consult with each other on,
all the information relating to the Company or any member of the Omnipoint Group
or any Omnipoint Investment, as 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, Omnipoint and the Company shall prepare all appropriate applications
for FCC approval, and such other documents as may be required, with respect to
the transfer of control of the Company to Omnipoint (collectively, the "FCC
Applications"). Not later than the third Business Day following execution and
delivery of this Agreement, Omnipoint and the Company will exchange with each
other their respective completed portions of the FCC Applications. Not later
than the fifth Business Day following the execution and delivery of this
Agreement, Omnipoint and the Company shall file, or cause to be filed, the FCC

                                      A-37
<PAGE>   141

Applications. If the Effective Time shall not have occurred for any reason
within any applicable initial consummation period, and neither Omnipoint nor the
Company shall have terminated this Agreement pursuant to Section 10.1, Omnipoint
and the Company 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 the Company. Each of the Company and Omnipoint shall bear
its own expenses in connection with the preparation and prosecution of the FCC
Applications. The Company 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, the Company 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. The Company 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: (1) as promptly as possible and in any
event within 15 days after the date hereof file with any other applicable
Governmental Bodies (including, but 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, (2) cooperate with each other as may reasonably be requested in
connection with the foregoing, and (3) otherwise use their best efforts to
obtain promptly the requested consent and approval of the applications by any
applicable Governmental Bodies. The Company 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 (other than SEC filing fees and fees payable under this HSR
Act).

SECTION 8.2  Registration Statement and Information Statement.

     The Company 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 Merger Shares issuable in
connection with the Merger, a portion of which Registration Statement shall also
serve as the information statement with respect to the stockholders of the
Company in connection with the Transactions (the "Information
Statement/Prospectus"). The respective parties shall cause the Information
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. Omnipoint shall use all reasonable efforts,
and the Company shall cooperate with Omnipoint, to have the Form S-4 declared
effective by the SEC prior to the Effective Time and to keep the Form S-4
effective as long as is necessary to consummate the Transactions. Omnipoint
shall, as promptly as practicable, provide copies of any written comments
received from the SEC with respect to the Form S-4 to the Company and advise the
Company of any verbal comments with respect to the Form S-4 received from the
SEC. Omnipoint shall use its best efforts to obtain, prior to the effective

                                      A-38
<PAGE>   142

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. Omnipoint agrees that the Information Statement/Prospectus and
each amendment or supplement thereto at the time of the mailing thereof; 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 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 Omnipoint in reliance upon and
in conformity with written information concerning the Company furnished to
Omnipoint by the Company specifically for use in the Information Statement/
Prospectus. The Company agrees that the written information concerning the
Company specifically provided by it for inclusion in the Information
Statement/Prospectus and each amendment or supplement thereto, at the time of
mailing thereof, or, in the case of written information concerning the Company
provided by the Company specifically 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 Information Statement/Prospectus
shall be made by the Company or Omnipoint without the approval of the other
party. Omnipoint shall advise the Company, 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 Omnipoint 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 Information Statement/Prospectus or the Form S-4 or
comments thereon and responses thereto or requests by the SEC for additional
information. Omnipoint shall pay all fees and expenses, other than attorneys'
and accounting fees and expenses, incurred in relation to the printing and
filing of the Form S-4 and the Information Statement/Prospectus.

SECTION 8.3  Public Announcements.

     So long as this Agreement is in effect, Omnipoint and the Company 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 the Company
and Omnipoint will be authorized to execute and deliver, in the name and on
behalf of the Surviving Corporation any deeds, bills of sale, assignments or
assurances and to take and do, in the name and on behalf of the Surviving
Corporation, any other actions and things to vest, perfect or confirm of record
in the Surviving Corporation any and all right, title and interest in, to and
under any of the rights, properties or assets of the Company acquired or to be
acquired by the Surviving Corporation as a result of, or in connection with, the
Transactions.

     Each of Omnipoint and the Company 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 occurrence, or
     non-occurrence, of which would be reasonably expected to cause any
     representation or warranty made by it and contained herein to be untrue or
     inaccurate in any material respect at any time during the period commencing
     on the date hereof and ending at the Effective Time; provided, 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;

     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 the Company, or
     Section 5.11, in the case of Omnipoint, or which relate to the consummation
     of the Transactions; and

          (f) any event, condition or state of facts which could reasonably be
     expected to 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
the Merger to qualify as a reorganization described in Section 368(a) of the
Code that will not result in gain to Omnipoint or the Company (except as set
forth in Section 9.2(b)), to comply with their respective obligations under the
Side Agreement and to obtain the opinions of counsel referred to in Sections
9.2(b) and 9.3(b), including the execution of the letters of representation
referred to therein, and will not take any action reasonably likely to cause the
Merger not to so qualify. After the Effective Time, each Party covenants that it
will not take, or fail to take, any action that would cause the Merger not to
qualify as a reorganization described in Section 368(a) of the Code.

SECTION 8.7  Stockholders' Approval.

     (a) The Company will, (1) subject to Section 8.7(b), use its reasonable
best efforts to obtain the approval and adoption of this Agreement and the
Merger from its stockholders and (2) otherwise comply with all legal
requirements applicable to such approval.

     (b) Except as provided below, the Board of Directors of the Company shall

stockholders and the Company shall each take all lawful action to solicit such
approval, including timely mailing of the Information Statement/ Prospectus. The

Omnipoint, its recommendation to its stockholders, but only if: (1) the Board of
Directors of the Company determines in good faith by majority vote, on the basis
of the advice of the Company's 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; (2) the Company shall have delivered to Omnipoint three

previously terminated in accordance with Article 10, the Company shall submit
this Agreement to its stockholders, even if the Company's Board of Directors
determines at any time after the date hereof that it is no longer advisable or
recommends that its stockholders reject it.

     form and substance reasonably acceptable to Omnipoint, on the basis of

     federal income tax purposes as a reorganization described in Section 368(a)
     of the Code and will not result in recognition of gain by Omnipoint or the
     Company, except for (i) gain, if any, resulting from the purchase by
     Omnipoint of shares of the Additional Capital Stock of the Company pursuant
     to the Securities Purchase Agreement and Section 6.2 and (ii) gain, if any,

     acceptable to Piper & Marbury and Latham & Watkins;

              Notwithstanding the foregoing, the condition set forth in this
     Section 9.2(b) shall be deemed to have been satisfied if such opinion could
     be delivered but for the failure (or possible failure) of the Merger to
     satisfy the continuity of interest requirement of Treas. Reg. Section 1.

     immediately prior to the Effective Time shall be Dissenting Shares;
     provided that shares of Company Common Stock held by Omnipoint or its
     Affiliates will in no event constitute Dissenting Shares for the purpose of
     this Section 9.2(e);

          (f) Omnipoint shall have received a certificate signed by an executive
     officer of the Company setting forth the Company's Bank Account
     Information; and

          (g) the FCC Consent shall have become a Final Order and shall not

     conditions would be reasonably expected to have an Omnipoint Material
     Adverse Effect.

SECTION 12.11  Captions.

     The captions herein are included for convenience of reference only and

SECTION 12.12  Severability.

     If any term, provision, covenant or restriction of this Agreement is held
by a court of competent jurisdiction or other authority to be invalid, void or
unenforceable, the remainder of the terms, provisions, covenants and
restrictions of this Agreement shall remain in full force and effect and shall
in no way be affected, impaired or invalidated so long as the economic or legal
substance of the Transactions is not affected in any manner materially adverse
to any party. Upon such a determination, the parties shall negotiate in good
faith to modify this Agreement so as to effect the original intent of the
parties as closely as possible in an acceptable manner so that the Transactions

SECTION 12.13  Intentionally Omitted.

SECTION 12.14  Schedules.

     (a) Each of Omnipoint and the Company has set forth information in its
respective Disclosure Schedules in a section thereof that corresponds to the
section of this Agreement to which it relates. A matter set forth in one section
of the Disclosure Schedules must be set forth in any other relevant section of
the Disclosure Schedules irrespective of its relevance to the latter section of
the Disclosure Schedules or section of the Agreement being apparent on the face
of the information disclosed in the Disclosure Schedules. The fact that any item
of information is disclosed in a Disclosure Schedule to this Agreement shall not
be construed to mean that such information is required to be disclosed by this
Agreement. Such information and the dollar thresholds set forth herein shall not
be used as a basis for interpreting the terms "material" or "Material Adverse
Effect" or other similar terms in this Agreement except as otherwise expressly
set forth in such Disclosure Schedules.

     (b) Notwithstanding anything herein to the contrary, each of Omnipoint and
the Company shall have the right to update the information contained in its
respective Disclosure Schedules on or before the Closing by delivering updated
schedules to Omnipoint (in the case of the Company) and the Company (in the case
of Omnipoint). Omnipoint and the Company hereby agree that any changes contained
in any such updated schedules shall not constitute a breach of their related
representations and warranties; provided, however, that each of Omnipoint and
the Company shall have the right to terminate this Agreement in the event that
any such change(s) results in a Company Material Adverse Effect or an Omnipoint
Material Adverse Effect, respectively, as provided in Section 10.1(c)(5) and
Section 10.1(d)(3) hereof.

SECTION 12.15  VoiceStream Actions.

     (a) Notwithstanding anything to the contrary contained in this Agreement,
the Side Agreement or any other documents, agreements or other instruments
entered into in connection herewith (each, a "Related Agreement" and
collectively, the "Related Agreements"), the Parties hereby agree that (i) no
provision contained herein or in any Related Agreement shall be deemed to limit,
restrict or prohibit Omnipoint or VoiceStream or Holdings from taking (or
failing to take) any action, including but not limited to, any action permitted
by the VoiceStream Merger Agreement as amended from time to time at the sole
discretion of VoiceStream, Holdings and Omnipoint (except as provided in Section
2(c) of the Side Agreement) or any action which in its sole discretion it takes
(or fails to take) in order: (1) to consummate the transactions contemplated by
the VoiceStream Merger Agreement, as amended from time to time at the sole
discretion of VoiceStream and Omnipoint; (2) to fulfill or satisfy the
conditions set forth in Article 9 of the VoiceStream Merger Agreement; or (3) to
ensure that the receipt of VoiceStream Holdings Common Stock by Omnipoint
stockholders pursuant to the VoiceStream Merger will be tax-free to such
Omnipoint stockholders (any such action, a "VoiceStream Action") and (ii) a
VoiceStream Action shall not constitute a "breach" of this Agreement or any
Related Agreement or of any representation, warranty, covenant or agreement
contained herein or in any Related Agreement if as a result of such VoiceStream
Action there shall occur a breach of any representation, warranty, covenant or
agreement contained herein or in any other Related Agreement; provided, however,
that: (x) each Party shall use its reasonable efforts to consider taking any
action which would allow it to fulfill or satisfy the conditions set forth in
Article 9 hereof, it being understood that the decision to take (or not take)
any action will be made at the sole discretion of VoiceStream, Omnipoint and
Holdings; (y) nothing herein shall be construed so as to require the Company to
consummate the Transactions unless the conditions set forth in Article 9 hereof
have been satisfied or waived; and (z) the Company's failure to consummate the
Transactions due to any VoiceStream Action that would, but for this Section
12.15(a) or Section 10(h) of the Side Agreement constitute a breach by Omnipoint
or VoiceStream or Holdings of a representation, warranty, covenant or agreement
contained herein or in any Related Agreement, shall not, provided that the
Company has validly terminated this Agreement in accordance with Section
12.15(b), constitute a breach of this Agreement, any Related Agreement or of any
representation, warranty, covenant or agreement contained herein or therein.

     (b) In the event that, but for the effect of paragraph (a) above or Section
10(h) of the Side Agreement, a VoiceStream Action would cause a material breach
of this Agreement or any Related Agreement or of any representation, warranty,
covenant or agreement contained herein or in any Related Agreement by Omnipoint,
VoiceStream, Holdings or any other party to any Related Agreement (such
VoiceStream Action, a "Material VoiceStream Action"), Omnipoint, VoiceStream or
Holdings shall have the right to take any action ("Cure") that would cause such
VoiceStream Action not to continue to constitute a Material VoiceStreamAction.
Any such Cure must occur during the thirty (30) day period immediately following
the delivery of written notice (the "Material Voice Stream Action Notice") to
the Company of the occurrence of such Material VoiceStream Action which the
Person taking such Material VoiceStream shall deliver prior to the taking of any
such Material VoiceStream Action. In the event that Omnipoint, VoiceStream,
Holdings or other party to any Related Agreement, as the case may be, shall fail
to Cure during such 30-day period (the "Cure Period"), then during the thirty
(30) day period immediately following such Cure Period (the "Termination
Period"), the Company shall have the right to terminate this Agreement pursuant
to Section 10.1(d)(4) (and not pursuant to Section 10.1(d)(1)) (the "Termination
Right"). In the event that (i) the Company terminates this Agreement pursuant to
the Termination Right during the Termination Period and (ii) within the
Termination Period and prior to the termination of the Agreement, the Company
requests in writing that Omnipoint purchase 250,000 shares of Class A Common
Stock (such request, the "Company Request"), then within ten (10) Business Days
immediately following the date of such termination, Omnipoint shall purchase
250,000 shares of Class A Common Stock at a per share purchase price of $20 per
share, for an aggregate purchase price of

                                      A-54
<PAGE>   158

$5,000,000, on substantially similar terms and conditions as set forth in the
Securities Purchase Agreement (the "Additional Stock Purchase"). In the event
that the Company does not deliver the Company Request within the Termination
Period and terminates this Agreement during the Termination Period, Omnipoint
shall have no obligation or liability with respect to the Additional Stock
Purchase. In the event that the Company does not exercise the Termination Right
to terminate the Agreement within the Termination Period, then clause (ii) of
paragraph (a) above shall apply to such Material VoiceStream Action(s) that gave
rise to the Termination Right and the first clause of subclause (y) of clause
(ii) of paragraph (a) shall not apply with respect to such Material VoiceStream
Action(s).

     (c) Notwithstanding paragraphs (a) and (b) of this Section 12.15 or Section
10(h) of the Side Agreement, paragraph (a) and Section 10(h) of the Side
Agreement shall not apply solely for the purpose of determining whether the
conditions set forth in Article 9 hereof have been satisfied; provided, that if
the conditions set forth in Article 9 are not satisfied as the result of a
Material VoiceStream Action or VoiceStream Actions that constitute in the
aggregate a Material VoiceStream Action, and the Company does not terminate the
Agreement during the 60-day time period immediately following the delivery of
the Material VoiceStream Action Notice with respect to such Material VoiceStream
Action, the conditions set forth in Article 9 shall be deemed to be satisfied
with respect to the Company's obligation to consummate the Transactions.

     IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
duly executed by their respective authorized officers as of the day and year
first above written.

                        DELAWARE GENERAL CORPORATION LAW

SEC.  262 APPRAISAL RIGHTS.

     (a) Any stockholder of a corporation of this State who holds shares of
stock on the date of the making of a demand pursuant to subsection (d) of this
section with respect to such shares, who continuously holds such shares through
the effective date of the merger or consolidation, who has otherwise complied
with subsection (d) of this section and who has neither voted in favor of the
merger or consolidation nor consented thereto in writing pursuant to sec. 228 of
this title shall be entitled to an appraisal by the Court of Chancery of the
fair value of the stockholder's shares of stock under the circumstances
described in subsections (b) and (c) of this section. As used in this section,
the word "stockholder" means a holder of record of stock in a stock corporation
and also a member of record of a non stock corporation; the words "stock" and
"share" mean and include what is ordinarily meant by those words and also
membership or membership interest of a member of a nonstock corporation; and the
words "depository receipt" mean a receipt or other instrument issued by a
depository representing an interest in one or more shares, or fractions thereof,
solely of stock of a corporation, which stock is deposited with the depository.

     (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to sec. 251 (other than a merger effected pursuant to sec. 251
(g) of this title), sec. 252, sec. 254, sec. 257, sec. 258, sec. 263 or sec. 264
of this title:

          (1) Provided, however, that no appraisal rights under this section
     shall be available for the shares of any class or series of stock, which
     stock, or depository receipts in respect thereof, at the record date fixed
     to determine the stockholders entitled to receive notice of and to vote at
     the meeting of stockholders to act upon the agreement of merger or
     consolidation, were either (i) listed on a national securities exchange or
     designated as a national market system security on an inter dealer
     quotation system by the National Association of Securities Dealers, Inc. or
     (ii) held of record by more than 2,000 holders; and further provided that
     no appraisal rights shall be available for any shares of stock of the
     constituent corporation surviving a merger if the merger did not require
     for its approval the vote of the stockholders of the surviving corporation
     as provided in subsection (f) of sec. 251 of this title.

          (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
     under this section shall be available for the shares of any class or series
     of stock of a constituent corporation if the holders thereof are required
     by the terms of an agreement of merger or consolidation pursuant to
     sec.sec. 251, 252, 254, 257, 258, 263 and 264 of this title to accept for
     such stock anything except:

             a. Shares of stock of the corporation surviving or resulting from
        such merger or consolidation, or depository receipts in respect thereof;

             b. Shares of stock of any other corporation, or depository receipts
        in respect thereof, which shares of stock (or depository receipts in
        respect thereof) or depository receipts at the effective date of the
        merger or consolidation will be either listed on a national securities
        exchange or designated as a national market system security on an inter
        dealer quotation system by the National Association of Securities
        Dealers, Inc. or held of record by more than 2,000 holders;

             c. Cash in lieu of fractional shares or fractional depository
        receipts described in the foregoing subparagraphs a. and b. of this
        paragraph; or

                                       B-1
<PAGE>   160

             d. Any combination of the shares of stock, depository receipts and
        cash in lieu of fractional shares or fractional depository receipts
        described in the foregoing subparagraphs a., b. and c. of this
        paragraph.

          (3) In the event all of the stock of a subsidiary Delaware corporation
     party to a merger effected under sec. 253 of this title is not owned by the
     parent corporation immediately prior to the merger, appraisal rights shall
     be available for the shares of the subsidiary Delaware corporation.

     (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as is practicable.

     (d) Appraisal rights shall be perfected as follows:

          (1) If a proposed merger or consolidation for which appraisal rights
     are provided under this section is to be submitted for approval at a
     meeting of stockholders, the corporation, not less than 20 days prior to
     the meeting, shall notify each of its stockholders who was such on the
     record date for such meeting with respect to shares for which appraisal
     rights are available pursuant to subsections (b) or (c) hereof that
     appraisal rights are available for any or all of the shares of the
     constituent corporations, and shall include in such notice a copy of this
     section. Each stockholder electing to demand the appraisal of such
     stockholder's shares shall deliver to the corporation, before the taking of
     the vote on the merger or consolidation, a written demand for appraisal of
     such stockholder's shares. Such demand will be sufficient if it reasonably
     informs the corporation of the identity of the stockholder and that the
     stockholder intends thereby to demand the appraisal of such stockholder's
     shares. A proxy or vote against the merger or consolidation shall not
     constitute such a demand. A stockholder electing to take such action must
     do so by a separate written demand as herein provided. Within 10 days after
     the effective date of such merger or consolidation, the surviving or
     resulting corporation shall notify each stockholder of each constituent
     corporation who has complied with this subsection and has not voted in
     favor of or consented to the merger or consolidation of the date that the
     merger or consolidation has become effective; or

          (2) If the merger or consolidation was approved pursuant to sec. 228
     or sec. 253 of this title, each constituent corporation, either before the
     effective date of the merger or consolidation or within ten days
     thereafter, shall notify each of the holders of any class or series of
     stock of such constituent corporation who are entitled to appraisal rights
     of the approval of the merger or consolidation and that appraisal rights
     are available for any or all shares of such class or series of stock of
     such constituent corporation, and shall include in such notice a copy of
     this section; provided that, if the notice is given on or after the
     effective date of the merger or consolidation, such notice shall be given
     by the surviving or resulting corporation to all such holders of any class
     or series of stock of a constituent corporation that are entitled to
     appraisal rights. Such notice may, and, if given on or after the effective
     date of the merger or consolidation, shall, also notify such stockholders
     of the effective date of the merger or consolidation. Any stockholder
     entitled to appraisal rights may, within 20 days after the date of mailing
     of such notice, demand in writing from the surviving or resulting
     corporation the appraisal of such holder's shares. Such demand will be
     sufficient if it reasonably informs the corporation of the identity of the
     stockholder and that the stockholder intends thereby to demand the
     appraisal of such holder's shares. If such notice did not notify
     stockholders of the effective date of the merger or consolidation, either
     (i) each such constituent corporation shall send a second notice before the
     effective date of the merger or consolidation notifying each of the holders
     of any class or series of stock of such constituent corporation that are
     entitled to appraisal rights of the effective date of the merger or
     consolidation or (ii) the surviving

                                       B-2
<PAGE>   161

     or resulting corporation shall send such a second notice to all such
     holders on or within 10 days after such effective date; provided, however,
     that if such second notice is sent more than 20 days following the sending
     of the first notice, such second notice need only be sent to each
     stockholder who is entitled to appraisal rights and who has demanded
     appraisal of such holder's shares in accordance with this subsection. An
     affidavit of the secretary or assistant secretary or of the transfer agent
     of the corporation that is required to give either notice that such notice
     has been given shall, in the absence of fraud, be prima facie evidence of
     the facts stated therein. For purposes of determining the stockholders
     entitled to receive either notice, each constituent corporation may fix, in
     advance, a record date that shall be not more than 10 days prior to the
     date the notice is given, provided, that if the notice is given on or after
     the effective date of the merger or consolidation, the record date shall be
     such effective date. If no record date is fixed and the notice is given
     prior to the effective date, the record date shall be the close of business
     on the day next preceding the day on which the notice is given.

     (e) Within 120 days after the effective date of the merger or
consolidation, the surviving or resulting corporation or any stockholder who has
complied with subsections (a) and (d) hereof and who is otherwise entitled to
appraisal rights, may file a petition in the Court of Chancery demanding a
determination of the value of the stock of all such stockholders.
Notwithstanding the foregoing, at any time within 60 days after the effective
date of the merger or consolidation, any stockholder shall have the right to
withdraw such stockholder's demand for appraisal and to accept the terms offered
upon the merger or consolidation. Within 120 days after the effective date of
the merger or consolidation, any stockholder who has complied with the
requirements of subsections (a) and (d) hereof, upon written request, shall be
entitled to receive from the corporation surviving the merger or resulting from
the consolidation a statement setting forth the aggregate number of shares not
voted in favor of the merger or consolidation and with respect to which demands
for appraisal have been received and the aggregate number of holders of such
shares. Such written statement shall be mailed to the stockholder within 10 days
after such stockholder's written request for such a statement is received by the
surviving or resulting corporation or within 10 days after expiration of the
period for delivery of demands for appraisal under subsection (d) hereof,
whichever is later.

     (f) Upon the filing of any such petition by a stockholder, service of a
copy thereof shall be made upon the surviving or resulting corporation, which
shall within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the addresses
therein stated. Such notice shall also be given by 1 or more publications at
least 1 week before the day of the hearing, in a newspaper of general
circulation published in the City of Wilmington, Delaware or such publication as
the Court deems advisable. The forms of the notices by mail and by publication
shall be approved by the Court, and the costs thereof shall be borne by the
surviving or resulting corporation.

     (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights. The Court may require the stockholders who have demanded an
appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.

<PAGE>   162

     (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or expectation of the merger or
consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors, including the rate of
interest which the surviving or resulting corporation would have had to pay to
borrow money during the pendency of the proceeding. Upon application by the
surviving or resulting corporation or by any stockholder entitled to participate
in the appraisal proceeding, the Court may, in its discretion, permit discovery
or other pretrial proceedings and may proceed to trial upon the appraisal prior
to the final determination of the stockholder entitled to an appraisal. Any
stockholder whose name appears on the list filed by the surviving or resulting
corporation pursuant to subsection (f) of this section and who has submitted
such stockholder's certificates of stock to the Register in Chancery, if such is
required, may participate fully in all proceedings until it is finally
determined that such stockholder not entitled to appraisal rights under this
section.

     (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or compound, as the Court
may direct. Payment shall be so made to each such stockholder, in the case of
holders of uncertificated stock forthwith, and the case of holders of shares
represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.

     (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.

     (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded appraisal rights as provided in subsection (d) of
this section shall be entitled to vote such stock for any purpose or to receive
payment of dividends or other distributions on the stock (except dividends or
other distributions payable to stockholders of record at a date which is prior
to the effective date of the merger or consolidation); provided, however, that
if no petition for an appraisal shall be filed within the time provided in
subsection (e) of this section, or if such stockholder shall deliver to the
surviving or resulting corporation a written withdrawal of such stockholder's
demand for an appraisal and an acceptance of the merger or consolidation, either
within 60 days after the effective date of the merger or consolidation as
provided in subsection (e) of this section or thereafter with the written
approval of the corporation, then the right of such stockholder to an appraisal
shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court
of Chancery shall be dismissed as to any stockholder without the approval of the
Court, and such approval may be conditioned upon such terms as the Court deems
just

     (l) The shares of the surviving or resulting corporation to which the
shares of such objecting stockholders would have been converted had they
assented to the merger or consolidation shall have the status of authorized and
unissued shares of the surviving or resulting corporation.

                                   AGREEMENT

     THIS AGREEMENT (the "Agreement") is dated October 22, 1999, by and among
East/West Communications, Inc., a Delaware corporation ("East West"), Omnipoint
Corporation, a Delaware corporation ("Omnipoint"), VoiceStream Wireless
Corporation, a Washington corporation ("VoiceStream"), and VoiceStream Wireless
Holding Corporation, a Delaware corporation ("Holdings"). East West, Omnipoint,
VoiceStream, and Holdings shall be referred to herein as the "Parties".

                                    RECITALS

     WHEREAS, concurrently herewith, East West and Omnipoint are entering into
an Agreement and Plan of Merger (the "Merger Agreement") pursuant to which,
among other things, East West will merge with and into Omnipoint (such merger,
together with the related transactions contemplated in the Merger Agreement,
being referred to herein as the "Merger");

     WHEREAS, as a condition to its entering into the Merger Agreement, East
West has required that the Parties enter into this Agreement;

     WHEREAS, it is desired that the Merger qualify as a tax-free reorganization
under Section 368(a) of the Internal Revenue Code of 1986, as amended (the
"Code");

                                   AGREEMENT

     NOW THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements set forth herein, the parties hereto agree as follows:

     1. Definitions.  Capitalized terms used herein and not otherwise defined
have the meaning ascribed to such terms in the Merger Agreement.

     2. Consent to the Merger Agreement; Amendment of VoiceStream Merger
Agreement.

          (a) Pursuant to Section 6.1 of the VoiceStream Merger Agreement,
     VoiceStream hereby consents to the Merger Agreement and the Transactions,
     including, without limitation, Article 11 of the Merger Agreement. In
     addition, to the extent that the Merger is consummated after the
     VoiceStream Merger, Holdings hereby agrees to cause Omnipoint to perform
     its obligations under the Merger Agreement and the Transactions, and agrees
     to perform its obligations under the Merger Agreement and the Transactions
     as if it were a party thereto.

          (b) Each of Omnipoint, VoiceStream and Holdings hereby agrees to amend
     the VoiceStream Merger Agreement (the "Initial Amendment") as soon as
     practicable after the date hereof, but in no event later than the Effective
     Time, as may be necessary to effectuate the exchange of each Merger Share
     that is issued and outstanding immediately after the Effective Time and
     immediately prior to the effective time of the VoiceStream Merger for the
     right to receive the Standard Election Consideration (as defined in the
     VoiceStream Merger Agreement) multiplied by the Conversion Ratio. The terms
     and substance of the Initial Amendment shall be reasonably acceptable to
     East West.

          (c) Following the Initial Amendment, unless the Merger Agreement is
     terminated, each of Omnipoint, VoiceStream and Holdings hereby agrees not
     to amend the VoiceStream Merger Agreement in a manner that would, upon the
     effective time of the VoiceStream Merger, result in the failure of holders
     of Series E Preferred Stock to receive the right to receive the Standard
     Election Consideration multiplied by the Conversion Ratio, unless as a
     result of such amendment

                                       C-1
<PAGE>   164

     the holders of Series E Preferred shall have the right to receive the same
     consideration that the holders of Omnipoint Common Stock receive in lieu of
     the Standard Election multiplied by the Conversion Ratio, assuming for this
     paragraph that prior to such amendment, such holders of Omnipoint Common
     Stock elected to receive the Standard Election Consideration and did not
     modify such election.

     3. Recapitalization of Omnipoint Preferred Stock.  Prior to or
simultaneously with the consummation of the VoiceStream Merger, each of
VoiceStream and Omnipoint hereby agree that the Omnipoint Preferred Stock shall
be recapitalized in accordance with the terms set forth below (the
"Recapitalization"):

          (a) The Certificate of Designation establishing the designations,
     powers, preferences, limitations, restrictions, and relative rights of the
     7% Cumulative Convertible Preferred Stock of Omnipoint (the "Convertible
     Preferred") shall be amended to provide that the Convertible Preferred
     shall be entitled to 10,445,123 votes which is the number of votes equal in
     the aggregate to the number of votes to which the number of whole shares of
     the common stock of Omnipoint (the "Common Stock") into which such shares
     of Convertible Preferred are convertible would be entitled with respect to
     any and all matters presented to the stockholders of Omnipoint for their
     action or consideration assuming a conversion price of $31.115 per share,
     and shall vote with the holders of shares of the Common Stock and any other
     class of stock entitled to vote and not as a separate class.

          (b) The Certificate of Designation establishing the designations,
     powers, preferences, limitations, restrictions, and relative rights of the
     Series A Non-Voting Convertible Preferred Stock of Omnipoint (the "Series A
     Convertible Preferred") shall be amended to provide that the Series A
     Convertible Preferred shall be entitled to 8,750,000 votes which is the
     number of votes equal in the aggregate to seven-tenths (7/10ths) the number
     of votes to which the number of whole shares of Common Stock into which
     such shares of Series A Convertible Preferred are convertible would be
     entitled with respect to any and all matters presented to the stockholders
     of Omnipoint for their action or consideration, and shall vote with the
     holders of shares of Common Stock and any other class of stock entitled to
     vote and not as a separate class.

     4. Reserved.

     5. Representations, Warranties and Covenants of Holdings.  Holdings hereby
represents, warrants and covenants to each of the other Parties as follows:

          (a) Effect of Recapitalization and Conversion of Series A Convertible
     Preferred. Assuming the validity of the Recapitalization under applicable
     state law, as a result of the Recapitalization and the Transfer and the
     Holdings Conversion, if applicable, immediately after the VoiceStream
     Merger, Holdings (1) will directly own shares of the capital stock of
     Omnipoint representing at least 80% of the total combined voting power of
     all outstanding shares of all classes of Omnipoint stock, (the "80% Voting
     Power") (2) will "control" Omnipoint within the meaning of Code Section
     368(c) as in effect on the date hereof and (3) has no current plan or
     intention to take, any action that would result in Holdings owning less
     than the 80% Voting Power or take any other action that would prevent
     Holdings from controlling Omnipoint subsequent to the VoiceStream Merger
     within the meaning of Section 368(c) of the Code as in effect on the date
     hereof.

          (b) Holdings has no current plan or intention to dispose of any of the
     capital stock of Omnipoint, provided, however, that Holdings may transfer
     stock of Omnipoint to a single member limited liability company which is
     treated as a disregarded entity (under Treas. Reg. Section 301.7701-3) for
     federal income tax purposes.

                                       C-2
<PAGE>   165

          (c) Provided that, at the later of the Effective Time of the Merger
     and the effective time of the VoiceStream Merger if it occurs after the
     Merger, the Merger qualifies as a reorganization within the meaning of Code
     Section 368(a) as in effect on the date hereof, Holdings will not take or
     cause Omnipoint to take, any action after such later time that would cause
     the Merger to fail so to qualify.

     6. Representation and Warranties of Omnipoint.  Omnipoint hereby represents
and warrants to each of the Parties that: (i) as of the close of business on
October 19, 1999, Omnipoint had outstanding 53,857,909 shares of Common Stock;
(ii) as of the date hereof, Omnipoint has outstanding 12,500 shares of Series A
Convertible Preferred, 50 percent of which is owned by Hutchison and 50 percent
of which is owned by VoiceStream which is convertible into 12,500,000 shares of
Omnipoint Common Stock and 325,000 shares of Convertible Preferred Stock, which
is convertible into 10,445,123 shares of Omnipoint Common Stock; and (iii) no
action or consent on the part of Hutchinson Telecommunications PCS (USA) Limited
or any other party (other than VoiceStream and Omnipoint) is required to effect
the Recapitalization.

     7. Representations, Warranties and Covenants of VoiceStream.  VoiceStream
hereby represents and warrants to each of the other parties that VoiceStream
holds 6,250 shares of Series A Convertible Preferred and has no current plan or
intention to dispose of any such shares or convert such shares to Omnipoint
Common Stock.

     8. Reserved.

     9. Effectiveness and Termination.  It is a condition precedent to the
effectiveness of this Agreement that the Merger Agreement shall have been
executed and delivered and be in full force and effect. In the event the Merger
Agreement is terminated in accordance with its terms, this Agreement shall
automatically terminate and be of no further force or effect. 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.

     10. Miscellaneous.

          (a) Amendments; No Waivers.

             (i) Subject to applicable law, any provision of this Agreement may
        be amended or waived, but only if such amendment or waiver is in writing
        and is signed, in the case of an amendment, by each party to this
        Agreement or, in the case of a waiver, by each party against whom the
        waiver is to be effective.

             (ii) No failure or delay by any party in exercising any right,
        power or privilege hereunder shall operate as a waiver thereof, nor
        shall any single or partial exercise thereof preclude any other or
        further exercise thereof, or the exercise of any other right, power or
        privilege. The rights and remedies herein provided shall be cumulative
        and not exclusive of any rights or remedies provided by law.

          (b) Successors and Assigns.  This Agreement shall be binding upon and
     shall inure to the benefit of and be enforceable by the Parties and their
     respective successors and assigns, including, without limitation, in the
     case of any corporate party hereto any corporate successor by merger or
     otherwise, and no Party shall assign its rights under this Agreement
     without the written consent of the other Parties.

          (c) Governing Law.  This Agreement shall be governed by and construed
     in accordance with the laws of the State of Delaware, without regard to the
     conflicts of law rules of such State.

          (d) Jurisdiction.  Any suit, action or proceeding seeking to enforce
     any provision of, or based on any matter arising out of or in connection
     with, this Agreement or the transactions contemplated

                                       C-3
<PAGE>   166

     hereby shall be brought in any federal court located in the State of
     Delaware or any Delaware state court, and each of the parties hereby
     consents to the exclusive jurisdiction of such courts (and of the
     appropriate appellate courts therefrom) in any such suit, action or
     proceeding and irrevocably waives, to the fullest extent permitted by law,
     any objection that it may now or hereafter have to the laying of the venue
     of any such suit, action or proceeding in any such court or that any such
     suit, action or proceeding brought in any such court has been brought in an
     inconvenient forum. Process in any such suit, action or proceeding may be
     served on any party anywhere in the world, whether within or without the
     jurisdiction of any such court. Without limiting the foregoing, each party
     agrees that service of process on such party as provided in Section 6.a
     shall be deemed effective service of process on such party.

          (e) WAIVER OF JURY TRIAL.  EACH OF THE PARTIES HERETO HEREBY
     IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL
     PROCEEDING ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS
     CONTEMPLATED HEREBY.

          (f) Counterparts; Effectiveness.  This Agreement may be signed in any
     number of counterparts, each of which shall be an original, with the same
     effect as if the signatures thereto and hereto were upon the same
     instrument. This Agreement shall become effective when each party hereto
     shall have received counterparts hereof signed by all of the other parties
     hereto. No provision of this Agreement is intended to confer any rights,
     benefits, remedies, obligations or liabilities hereunder upon any Person
     other than the parties hereto and their respective successors and assigns.

          (g) Entire Agreement.  This Agreement, together with the Merger
     Agreement, constitutes the entire agreement between the parties with
     respect to the subject matter of this Agreement and supersedes all prior
     agreements and understandings, both oral and written, between the parties
     with respect to such subject matter.

          (h) VoiceStream Action.  Notwithstanding anything to the contrary
     contained in this Agreement, the Merger Agreement or any other documents,
     agreements or other instruments entered into in connection herewith (each,
     a "Related Agreement" and collectively, the "Related Agreements"), the
     Parties hereby agree that (i) no provision contained herein or in any
     Related Agreement shall be deemed to limit, restrict or prohibit Omnipoint,
     VoiceStream, Holdings or any other party to any Related Agreement from
     taking (or failing to take) any action, including but not limited to, any
     action permitted by the VoiceStream Merger Agreement as amended from time
     to time at the sole discretion of VoiceStream, Holdings and Omnipoint
     (except as provided in Section 2(c) hereof) or any action which in its sole
     discretion it takes (or fails to take) in order: (a) to consummate the
     transactions contemplated by the VoiceStream Merger Agreement, as amended
     from time to time at the sole discretion of VoiceStream and Omnipoint; (b)
     to fulfill or satisfy the conditions set forth in Article 9 of the
     VoiceStream Merger Agreement; or (c) to ensure that the receipt of
     VoiceStream Holdings Common Stock by Omnipoint stockholders pursuant to the
     VoiceStream Merger will be tax-free to such Omnipoint stockholders (any
     such action, a "VoiceStream Action"), and (ii) a VoiceStream Action shall
     not constitute a breach of this Agreement or any Related Agreement or of
     any representation, warranty, covenant or agreement contained herein or in
     any Related Agreement if as a result of such VoiceStream Action there shall
     occur a breach of any representation, warranty, covenant or agreement
     contained herein or in any other Related Agreement, subject to Section
     12.15(c) of the Merger Agreement.

          (i) Captions.  The captions herein are included for convenience of
     reference only and shall be ignored in the construction or interpretation
     hereof.

          (j) Severability.  If any term, provision, covenant or restriction of
     this Agreement is held by a court of competent jurisdiction or other
     authority to be invalid, void or unenforceable, the remainder of the terms,
     provisions, covenants and restrictions of this Agreement shall remain in
     full force and effect and shall in no way be affected, impaired or
     invalidated so long as the economic or legal substance of the transactions
     contemplated hereby is not affected in any manner materially adverse to any
     party. Upon such a determination, the parties shall negotiate in good faith
     to modify this Agreement so as to effect the original intent of the parties
     as closely as possible in an acceptable manner so that the transactions
     contemplated hereby be consummated as originally contemplated to the
     fullest extent possible.

          (k) Specific Performance.  The parties hereto agree that irreparable
     damage would occur if any provision of this Agreement were not performed in
     accordance with the terms hereof and that the parties shall be entitled to
     an injunction or injunctions to prevent breaches of this Agreement or to
     enforce specifically the performance of the terms and provisions hereof in
     any federal court located in the State of Delaware or any Delaware state
     court, in addition to any other remedy to which they are entitled at law or
     in equity.

          (l) Remedies Cumulative.  All rights, powers and remedies provided
     under this Agreement or otherwise available in respect hereof at law or in
     equity shall be cumulative and not alternative, and the exercise or
     beginning of the exercise of any thereof by any party shall not preclude
     the simultaneous or later exercise of any other such right, power or remedy
     by such party.

          (m) Limitation on Liability.  No party hereto shall have any liability
     hereunder for any actions or omissions of any other party hereto.

          (n) Expenses.  Each party hereto shall bear its own expenses incurred
     in connection with this Agreement.

          (o) Further Assurances.  Each party hereto agrees that such party
     shall execute and deliver such additional instruments and other documents
     and shall take such further actions as may be necessary or appropriate to
     effectuate, carry out and comply with all of their obligations under this
     Agreement and to ensure that Holdings is in "control" of Omnipoint within
     the meaning of Section 368(c) of the Code as in effect on the date hereof.
     Without limiting the generality of the foregoing, none of the parties
     hereto shall enter into any agreement or arrangement (or alter, amend or
     terminate any existing agreement or arrangement) if such action would
     impair the ability of any party to effectuate, carry out or comply with all
     the terms of this Agreement.

ITEM 20.  INDEMNIFICATION OF OFFICERS AND DIRECTORS

     Section 145 of the General Corporation Law of the State of Delaware (the
"DGCL") permits indemnification of directors, officers, agents and controlling
persons of a corporation under certain conditions and subject to certain
limitations. The registrant's by-laws include provisions to require the
registrant to indemnify its directors and officers to the fullest extent
permitted by DGCL Section 145, including circumstances in which indemnification
is otherwise discretionary. DGCL Section 145 also empowers the registrant to
purchase and maintain insurance that protects its officers, directors, employees
and agents against any liabilities incurred in connection with their service in
such positions.

     At present, there is no pending litigation or proceeding involving a
director or officer of the registrant as to which indemnification is being
sought nor is the registrant aware of any threatened litigation that may result
in claims for indemnification by any officer or director.

ITEM 22.  UNDERTAKINGS

     A. The undersigned registrant hereby undertakes:

          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this registration statement:

             (i) To include any prospectus required by Section 10(a)(3) of the
        Securities Act of 1933.

             (ii) To reflect in the prospectus any facts or events arising after
        the effective date of the registration statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the registration statement. Notwithstanding the foregoing, any
        increase or decrease in volume of securities offered (if the total
        dollar amount of securities offered would not exceed that which was
        registered) and any deviation from the low or high end of the estimated
        offering range may be reflected in the form of prospectus filed with the
        SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume
        and price represent no more than a 20 percent change in the maximum
        aggregate offering price set forth in the "Calculation of Registration
        Fee" table in the effective registration statement.

             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in the registration statement
        or any material change to such information in the registration
        statement.

          (2) That, for the purpose of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.

          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.

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

     C.  (1) The undersigned registrant hereby undertakes as follows: that prior
to any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other items of the applicable form.

                                      II-2
<PAGE>   171

          (2) The undersigned registrant hereby undertakes that every prospectus
     (i) that is filed pursuant to the paragraph immediately preceding, or (ii)
     that purports to meet the requirements of Section 10(a)(3) of the
     Securities Act and is used in connection with an offering of securities
     subject to Rule 415, will be filed as a part of an amendment to the
     registration statement and will not be used until such amendment is
     effective, and that, for purposes of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provisions referred to in Item 20 of this
registration statement, or otherwise, the registrant has been advised that in
the opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the registrant of expenses incurred or
paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

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

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

                                      II-3

                                   SIGNATURES


     Pursuant to the requirements of the Securities Act, the registrant has duly
caused this amendment to registration statement to be signed on its behalf by
the undersigned, thereunto duly authorized, in the city of Bethesda, in the
state of Maryland on January 25, 2000.

Suite 400
Bethesda, Maryland  20814

Gentlemen:

     We have assisted in the preparation and filing with the Securities and
Exchange Commission of a Registration Statement on Form S-4 (the "Registration
Statement"), relating to 1,775,000 shares of Common Stock, $0.01 par value per
share, of Omnipoint Corporation, a Delaware corporation (the "Company") and
7,000,000 shares of Series E Preferred Stock, par value $0.01 par value per
share, of the Company (collectively, the "Shares"), to be issued in connection
with the merger of East/West Communications, Inc. ("East/West") with the
Company.

     We have examined the Certificate of Incorporation and By-laws of the
Company, and all amendments thereto, and have examined and relied upon the
originals, or copies certified to our satisfaction, of such records of meetings
of the directors and stockholders of the Company, documents and other
instruments as in our judgment are necessary or appropriate to enable us to
render the opinions expressed below.

     In examining the foregoing documents, we have assumed the genuineness of
all signatures and the authenticity of all documents submitted to us as
originals, the conformity to original documents of all documents submitted to us
as certified or photostatic copies, and the authenticity of the originals of
such latter documents.

     Based on the foregoing, we are of the opinion that the Shares have been
duly authorized and, when issued upon consummation of the Merger in accordance
with the terms and provisions of the Agreement and Plan of Merger, by and
between the Company and East/West, dated as of October 22, 1999, will be duly
and validly issued, fully paid and nonassessable.

     We hereby consent to the use of our name in the Registration Statement and
under the caption "Legal Matters" in the related Prospectus/Proxy Statement and
consent to the filing of this opinion as an exhibit to the Registration
Statement.

                                           Very truly yours,

Re:  Material United Stated Federal Income Tax Consequences of the East/West
     Merger

Ladies and Gentlemen:

       We have acted as tax counsel for East/West Communications, Inc., a
Delaware corporation ("East/West"), in connection with the proposed merger (the
"East/West Merger") of East/West with and into Omnipoint Corporation, a Delaware
corporation ("Omnipoint"), pursuant to an Agreement and Plan of Merger, dated as
of October 22, 1999, (the "Merger Agreement") by and between East/West and
Omnipoint.

       In connection with the filing by Omnipoint of a registration statement
(the "Registration Statement") on Form S-4, which includes the proxy
statement/prospectus relating to the Merger Agreement, East/West has requested
our opinion regarding certain material United States federal income tax
consequences of the East/West Merger. In providing our opinion, we have examined
and are relying upon (without any independent investigation or review thereof)
the truth and accuracy, at all relevant times, of the statements, covenants,
representations and warranties contained in (i) the Merger Agreement, (ii) the
Registration Statement to be filed by Omnipoint with the Securities and Exchange
Commission (the "SEC"), to which this opinion appears as an exhibit, (iii) the
certificates that will be delivered to us at the effective time of the East/West
Merger by officers of East/West, Omnipoint, VoiceStream Wireless Corporation and
VoiceStream Holdings Corporation, and (iv) such other documents and corporate
records as we have deemed necessary or appropriate for purposes of our opinion.

       Based on such facts, assumptions and representations and subject to the
limitations set forth in the Registration Statement, the statements in the
Registration Statement set forth under the caption "Material United Stated
Federal Income Tax Consequences of the East/West Merger," to the extent such
statements constitute matters of law, summaries of legal matters or legal
conclusions, are the material federal income tax consequences relevant to (i)
holders of East/West common stock who, pursuant to the East/West Merger,
exchange their East/West common stock for either Omnipoint common stock,
Omnipoint Series E Preferred Stock or VoiceStream Holdings common stock, as the
case may be, and (ii) holders of East/West


<PAGE>   2

preferred stock whose stock is acquired pursuant to the East/West Merger for
cash. No opinion is expressed as to any matter not discussed herein.

       This opinion represents and is based upon our best judgment regarding the
application of United States federal income tax laws arising under the Internal
Revenue Code of 1986, as amended, existing judicial decisions, administrative
regulations and published rulings and procedures. Our opinion is not binding
upon the Internal Revenue Service or the courts, and there is no assurance that
the Internal Revenue Service will not assert a contrary position. Furthermore,
no assurance can be given that future legislative, judicial or administrative
changes, on either a prospective or retroactive basis, would not adversely
affect the accuracy of the conclusions stated herein. Nevertheless, we undertake
no responsibility to advise you or your shareholders of any new developments in
the application or interpretation of the United States federal income tax laws
after the effectiveness of the Registration Statement. In addition, any
variation or difference in the facts, representations or assumptions recited or
referred to hereinabove, could affect the conclusions stated herein.

       This opinion is rendered to you for use in connection with the filing of
the Registration Statement with the SEC and is not to be used, circulated,
quoted or otherwise referred to for any other purpose without our express
written permission. We consent to the filing of this opinion as an exhibit to
the Registration Statement and to the references to our firm name therein.

                                Very truly yours,

case of a waiver, by each party against whom the waiver is to be effective.

federal court located in the State of Delaware or any Delaware state court, and
each of the parties hereby consents to the exclusive jurisdiction of such courts

anywhere in the world, whether within or without the jurisdiction of any such

determination, the parties shall negotiate in good faith to modify this
Agreement so as to effect the original intent of the parties as closely as
possible in an acceptable manner so that the transactions contemplated hereby be
