     457(f)(1) and 457(f)(2) and solely for the purpose of calculating the
     registration fee, the proposed maximum aggregate offering price is equal to
     (A) the aggregate market value of the approximate number of Powertel Common
     Shares to be cancelled in the VoiceStream/Powertel merger (calculated as
     set forth in note (7) above) based on a market value of $75.2188 per
     Powertel Common Share, the average of the high and low sale prices per
     Powertel Common Share on The Nasdaq Stock Market on September 27, 2000 and
     (B) one-third of the aggregate $3,500 par value of the Powertel Series A
     Preferred Shares, Powertel Series B Preferred Shares, Powertel Series D
     Preferred Shares, Powertel Series E Preferred Shares and Powertel Series F
     Preferred Shares, for which shares there is no market.

                                                                __________, 2000

Dear Fellow Stockholders:

     You are cordially invited to attend a special meeting of stockholders of
VoiceStream Wireless Corporation on __________, 2000, at 8:00 a.m., Pacific
time, at ____________.

     At the special meeting, you will have the chance to vote on two significant
proposed transactions:

     (1) a merger between VoiceStream and Deutsche Telekom AG in which
         VoiceStream would become a subsidiary of Deutsche Telekom; and

     (2) a merger between VoiceStream and Powertel, Inc. in which Powertel would
         become a subsidiary of VoiceStream.

     The purpose of our merger agreement with Deutsche Telekom is to provide for
Deutsche Telekom to acquire VoiceStream. The purpose of our merger agreement
with Powertel is to provide for VoiceStream to acquire Powertel if for any
reason the Deutsche Telekom/VoiceStream merger agreement is terminated before
completion. If our merger with Deutsche Telekom is completed, then Deutsche
Telekom is expected to acquire Powertel and VoiceStream's merger agreement with
Powertel will terminate.

     Therefore, although you are being asked to approve both mergers, if we
complete our merger with Deutsche Telekom, we will not merge with Powertel.

DEUTSCHE TELEKOM/VOICESTREAM MERGER

     The merger of VoiceStream and Deutsche Telekom provides VoiceStream the
opportunity to partner with one of the world's leading telecommunications
companies. If the merger is completed, VoiceStream will become a wholly-owned
subsidiary of Deutsche Telekom, and, in general, you will receive, for each of
your VoiceStream common shares, a combination of $30 in cash and 3.2 Deutsche
Telekom shares. If you prefer, in lieu of that combination you may elect to
receive for each of your VoiceStream common shares either $200 in cash or 3.7647
Deutsche Telekom shares, but those elections will be subject to proration. You
will receive Deutsche Telekom shares in the form of Deutsche Telekom American
depositary shares, which are traded on the New York Stock Exchange under the
symbol "DT", unless you elect to receive Deutsche Telekom shares in the form of
Deutsche Telekom ordinary shares, which are traded principally on the Frankfurt
Stock Exchange under the symbol "DTE". Each Deutsche Telekom ADS represents one
Deutsche Telekom ordinary share. We estimate that, in the merger between
VoiceStream and Deutsche Telekom, Deutsche Telekom will pay approximately
________ in cash and issue approximately ________ Deutsche Telekom shares to
VoiceStream stockholders, subject to adjustment. Those Deutsche Telekom shares
will represent approximately ____% of the equity of Deutsche Telekom after the
Deutsche Telekom/VoiceStream merger and approximately ____% of the equity of
Deutsche Telekom after the Deutsche Telekom/Powertel merger. The election,
proration and other adjustment procedures are described in greater detail in the
enclosed proxy statement/prospectus, and I urge you to review them carefully.

VOICESTREAM/POWERTEL MERGER

     The merger between VoiceStream and Powertel provides VoiceStream an
opportunity to expand its global system for mobile communications, or "GSM",
wireless coverage in the southeastern United States, a crucial and rapidly
growing market where we generally do not own licenses or market our services. If
the merger between VoiceStream and Powertel is completed, Powertel will become a
wholly-owned subsidiary of VoiceStream and holders of Powertel common shares
will receive VoiceStream common shares at a
<PAGE>   6

conversion ratio ranging from 0.65 to 0.75, depending on the average closing
price of VoiceStream common shares on 10 trading days randomly selected from the
20 trading-day period ending five trading days before the completion of the
VoiceStream/Powertel merger. Holders of Powertel preferred shares will receive
VoiceStream common shares using the same conversion ratio, treating the
preferred shares on an as-converted-to-common share basis. We estimate that, in
the merger between VoiceStream and Powertel, VoiceStream will issue
approximately ________ million VoiceStream common shares to Powertel
stockholders. Those shares will represent approximately ____% of the equity of
VoiceStream after the merger. Assuming the VoiceStream/Powertel merger is
completed (which can occur only if the Deutsche Telekom/VoiceStream merger is
not completed), the VoiceStream common shares, including the shares issued to
Powertel stockholders as a result of the VoiceStream/Powertel merger, will
continue to be traded on the Nasdaq Stock Market under the symbol "VSTR".

     YOUR BOARD OF DIRECTORS HAS DETERMINED THAT EACH OF THE PROPOSED MERGERS IS
ADVISABLE AND IN THE BEST INTERESTS OF VOICESTREAM AND ITS STOCKHOLDERS AND
RECOMMENDS THAT ALL STOCKHOLDERS VOTE "FOR" THE APPROVAL OF EACH OF THE MERGERS
AT THE SPECIAL MEETING. Goldman, Sachs & Co., VoiceStream's financial advisor,
has delivered separate written opinions in connection with each of the proposed
mergers to the effect that, as of the date of such opinions, the consideration
in aggregate to be received by holders of VoiceStream common shares in the
Deutsche Telekom/VoiceStream merger is fair to those holders from a financial
point of view, and the conversion ratio by which Powertel shares will be
converted into VoiceStream common shares under the VoiceStream/Powertel merger
agreement is fair to VoiceStream from a financial point of view. In addition,
you should be aware that VoiceStream stockholders who had sufficient voting
power as of the VoiceStream record date to approve each of the Deutsche Telekom/
VoiceStream merger and the VoiceStream/Powertel merger have agreed to vote in
favor of each of those mergers. Similarly, Powertel stockholders who had
sufficient voting power as of the Powertel record date to approve the
VoiceStream/Powertel merger have agreed to vote in favor of the
VoiceStream/Powertel merger. As a result, stockholder approval of both mergers
is assured.

     The accompanying notice of special meeting and proxy statement/prospectus
explain the proposed mergers and provide specific information concerning the
special meeting. Please read these materials carefully. YOU ALSO SHOULD
CAREFULLY CONSIDER THE RISK FACTORS RELATING TO THE MERGERS WHICH ARE DESCRIBED
BEGINNING ON PAGE __.

     I encourage you to vote on these important matters. To be certain that your
shares are voted at the special meeting, please sign, date and return the

                                __________, 2000

Dear Fellow Stockholders:

     You are cordially invited to attend a special meeting of stockholders of
Powertel, Inc. on __________, 2000, at 11:00 a.m., Eastern time, at The Cotton
Duck, 6101 20th Avenue, Valley, Alabama 36854.

     At the special meeting you will be asked to vote on (A) the proposed merger
between Powertel and Deutsche Telekom AG, in which Powertel would become a
subsidiary of Deutsche Telekom, and (B) the proposed merger between Powertel and
VoiceStream Wireless Corporation, in which Powertel would become a subsidiary of
VoiceStream.

     These two mergers are mutually exclusive. On July 23, 2000, Deutsche
Telekom and VoiceStream entered into a merger agreement that provides for
VoiceStream to merge with and become a wholly-owned subsidiary of Deutsche
Telekom. If the merger between VoiceStream and Deutsche Telekom is completed,
our merger agreement with Deutsche Telekom provides for Powertel to merge with
and become a wholly-owned subsidiary of Deutsche Telekom. In that circumstance,
both VoiceStream and Powertel would become wholly-owned subsidiaries of Deutsche
Telekom, and our separate merger agreement with VoiceStream would automatically
terminate.

     If, however, VoiceStream's merger agreement with Deutsche Telekom is
terminated, Powertel's merger agreement with Deutsche Telekom will also
terminate. In that circumstance, our merger agreement with VoiceStream provides
for Powertel to merge with and become a wholly-owned subsidiary of VoiceStream.

DEUTSCHE TELEKOM/POWERTEL MERGER

     The proposed merger of Powertel and Deutsche Telekom provides Powertel the
opportunity to partner with and become a part of one of the world's leading
telecommunications companies. If the merger with Deutsche Telekom is completed,
holders of Powertel common shares will receive 2.6353 Deutsche Telekom shares
for each Powertel common share. Holders of Powertel's Series A preferred shares
and Series B preferred shares will receive 121.9294 Deutsche Telekom shares for
each Powertel preferred share. Holders of Powertel's Series D preferred shares
will receive 93.0106 Deutsche Telekom shares for each Powertel preferred share.
Holders of Powertel's Series E preferred shares and Series F preferred shares
will receive (A) 179.5979 Deutsche Telekom shares for each Powertel preferred
share and (B) 2.6353 Deutsche Telekom shares multiplied by the number of
Powertel common shares representing accrued or declared but unpaid dividends on
each Powertel preferred share. The merger consideration is subject to
adjustment.

     You will receive Deutsche Telekom shares in the form of Deutsche Telekom
American depositary shares, which are traded on the New York Stock Exchange
under the symbol "DT", unless you elect to receive Deutsche Telekom shares in
the form of Deutsche Telekom ordinary shares, which are traded principally on
the Frankfurt Stock Exchange under the symbol "DTE". Each Deutsche Telekom
American depositary share represents one Deutsche Telekom ordinary share.

     We estimate that, in the merger between Deutsche Telekom and Powertel,
Deutsche Telekom will issue approximately ________ million Deutsche Telekom
shares to Powertel stockholders. Those shares will represent approximately
________% of the equity of Deutsche Telekom after the Deutsche Telekom/Powertel
merger and the Deutsche Telekom/VoiceStream merger.
<PAGE>   9

VOICESTREAM/POWERTEL MERGER

     The proposed merger of VoiceStream and Powertel provides Powertel with the
opportunity to become part of a nationwide wireless company that uses the global
system for mobile communications, or "GSM", wireless technology. If the merger
between VoiceStream and Powertel is completed, holders of Powertel common shares
will receive a number of VoiceStream common shares for each Powertel common
share as follows: (A) 0.75 if the average closing price of VoiceStream common
shares is $113.33 or below; (B) 0.65 if the average closing price of VoiceStream
common shares is $130.77 or above; or (C) if the average closing price of
VoiceStream common shares is greater than $113.33 and less than $130.77, the
quotient determined by dividing $85.00 by the average closing price of
VoiceStream common shares. The average closing price of VoiceStream common
shares will be determined by averaging the closing prices of VoiceStream common
shares on 10 trading days randomly selected from the 20 trading day period
ending five trading days before the completion of the VoiceStream/Powertel
merger.

     Holders of Powertel preferred shares will receive a number of VoiceStream
common shares determined by multiplying (A) the common stock exchange ratio for
Powertel common shares by (B) the sum of (1) the number of Powertel common
shares into which the Powertel preferred shares would be converted into as of
the completion of the VoiceStream/Powertel merger and (2) with respect to
Powertel's Series E preferred shares and Series F preferred shares, the number
of Powertel common shares that represents accrued or declared but unpaid
dividends on such preferred shares.

     We estimate that in the merger between VoiceStream and Powertel VoiceStream
will issue approximately ____ million VoiceStream common shares to Powertel
stockholders. Those shares would represent approximately ____% of the equity of
VoiceStream after the VoiceStream/Powertel merger. Assuming the
VoiceStream/Powertel merger is completed, which can only occur if the Deutsche
Telekom/VoiceStream merger is not completed, the VoiceStream common shares,
including the shares issued to Powertel stockholders as a result of the
VoiceStream/Powertel merger, will continue to be traded on the Nasdaq Stock
Market under the symbol "VSTR".

     YOUR BOARD OF DIRECTORS HAS DETERMINED THAT EACH OF THE PROPOSED MERGERS IS
ADVISABLE AND IN THE BEST INTERESTS OF POWERTEL AND ITS STOCKHOLDERS AND
RECOMMENDS THAT ALL COMMON AND PREFERRED STOCKHOLDERS VOTE "FOR" THE APPROVAL OF
EACH OF THE MERGERS AT THE SPECIAL MEETING. Morgan Stanley & Co. Incorporated,
Powertel's financial advisor, has delivered its oral opinion, later confirmed in
writing, that as of the date of that opinion, and subject to and based upon the
considerations set forth in its opinion, the consideration to be received by
holders of Powertel common shares and preferred shares pursuant to the Deutsche
Telekom/Powertel merger agreement was fair from a financial point of view to
such holders, and, if the Deutsche Telekom/Powertel merger is not completed, the
consideration to be received by holders of Powertel common shares and preferred
shares pursuant to the VoiceStream/Powertel merger agreement was fair from a
financial point of view to such holders. In addition, you should be aware that
Powertel stockholders who had sufficient voting power as of the Powertel record
date to approve each of the Deutsche Telekom/Powertel merger and the
VoiceStream/Powertel merger have agreed to vote in favor of each of those
mergers. Similarly, VoiceStream stockholders who had sufficient voting power as
of the record date to approve the VoiceStream/Powertel merger have agreed to
vote in favor of the VoiceStream/Powertel merger. As a result, stockholder
approval of both mergers is assured.

  VoiceStream and Powertel each have
     substantial operating losses and
     negative cash flow and
     VoiceStream may not become
     profitable following the
     VoiceStream/Powertel merger......    40
  There is a risk that VoiceStream's
     expansion will be constrained
     because its ability to expand and
     provide service nationally is
     limited by its ability to obtain
     FCC licenses.....................    40
  VoiceStream and Powertel are at risk
     of losing coverage in certain
     markets because they have entered
     into joint ventures that they do
     not control in an attempt to
     expand into those markets........    40
  The FCC and other regulatory
     agencies must approve the
     VoiceStream/ Powertel merger and

     adversely affect our business or
     financial condition..............    41

     venture entities in which
     VoiceStream holds interests could
     lose licenses as a result of
     court proceedings................    41

     emissions or other health and

                    QUESTIONS AND ANSWERS ABOUT THE MERGERS

Q. WHAT TRANSACTIONS ARE BEING PROPOSED?

A. Deutsche Telekom is proposing to acquire both VoiceStream and Powertel in
   separate merger transactions in which each of these companies would become a
   wholly-owned subsidiary of Deutsche Telekom.

   It is expected that these two merger transactions would occur at about the
   same time. However, Deutsche Telekom will only complete its acquisition of
   Powertel if it first completes its acquisition of VoiceStream. If the merger
   between Deutsche Telekom and VoiceStream is not completed, then VoiceStream
   is proposing to acquire Powertel in an alternative merger transaction in
   which Powertel would become a wholly-owned subsidiary of VoiceStream.

Q. WHY IS DEUTSCHE TELEKOM PROPOSING TO ACQUIRE VOICESTREAM AND POWERTEL?

A. The management and supervisory boards of Deutsche Telekom and the boards of
   directors of each of VoiceStream and Powertel believe that the combination of
   their three companies will create a company well positioned to provide
   current and next-generation wireless voice and data services on a global
   basis over a common technology platform. They also believe that the combined
   company will be capable of generating substantially more long-term
   shareholder value than could be achieved by any of our companies separately.
   Specifically, they believe the combined company will:

   - benefit U.S. consumers by creating a stronger and more competitive national
     wireless operator;

   - be able to accelerate the introduction of next-generation wireless voice
     and data services, such as mobile Internet and multimedia applications;

   - offer seamless global services over a common technology platform, and
     provide customer-friendly features, such as global roaming, certified
     billing and worldwide customer service; and

   - have the necessary capital resources, technology expertise and global reach
     to provide cost-competitive service.

Q. WHY IS VOICESTREAM PROPOSING TO ACQUIRE POWERTEL IF VOICESTREAM IS NOT
   ACQUIRED BY DEUTSCHE TELEKOM?

A. VoiceStream believes that if its transaction with Deutsche Telekom is
   terminated for any reason, then the acquisition of Powertel will make
   VoiceStream a more competitive national wireless telecommunications company.
   Powertel operates in 12 southeastern states of the United States in areas
   where VoiceStream generally does not operate, and Powertel's network is based
   on the same global system for mobile communications, or "GSM", wireless
   technology that VoiceStream uses. As a result, the addition of Powertel
   would:

   - fill a significant gap in VoiceStream's U.S. coverage;

   - create opportunities to improve VoiceStream's competitive position by
     providing customers with seamless services over a common technology
     platform on a nationwide basis; and

   - accelerate the introduction by VoiceStream of next-generation wireless
     voice and data services, such as mobile Internet and multimedia
     applications.

Q. WHAT AM I BEING ASKED TO VOTE ON?

A. If you are a VOICESTREAM stockholder, you are being asked to consider and
   vote on proposals to approve the Deutsche Telekom/VoiceStream merger and the
   VoiceStream/Powertel merger.

   If you are a POWERTEL stockholder, you are being asked to consider and vote
   on proposals to approve the Deutsche Telekom/Powertel merger and the
   VoiceStream/Powertel merger.

   The VoiceStream/Powertel merger can occur only if the Deutsche
   Telekom/VoiceStream merger is not completed and the merger agreement between
   Deutsche Telekom and VoiceStream is terminated.

Q. WHAT WILL I RECEIVE IN THESE MERGERS?

A. The consideration you will receive and detailed information about potential
   proration, adjustments or other factors that may affect what

                                        1
<PAGE>   20

you receive are described beginning on page __ of the Summary.

Q. WHEN ARE THE DEUTSCHE TELEKOM/VOICESTREAM AND DEUTSCHE TELEKOM/POWERTEL
   MERGERS EXPECTED TO BE COMPLETED?

A. We anticipate completing the Deutsche Telekom/VoiceStream merger in __ 2001,
   as soon as practicable following the receipt of all required stockholder and
   governmental approvals, and the Deutsche Telekom/Powertel merger shortly
   after the Deutsche Telekom/VoiceStream merger. However, because both mergers
   are subject to governmental approvals, we cannot predict the exact timing of
   their completion.

Q. WHEN IS THE VOICESTREAM/POWERTEL MERGER EXPECTED TO BE COMPLETED?

A. VoiceStream will complete the VoiceStream/Powertel merger only if the
   Deutsche Telekom/VoiceStream merger agreement is terminated. If the Deutsche
   Telekom/VoiceStream merger agreement is terminated, VoiceStream and Powertel
   would complete the VoiceStream/Powertel merger as soon as practicable
   following the receipt of all required stockholder and governmental approvals.

Q. SHOULD I SEND IN MY STOCK CERTIFICATES NOW?

A. No.

   VoiceStream Stockholders

   If you are a VoiceStream stockholder, then at least 45 days prior to the
   expected closing of the Deutsche Telekom/VoiceStream merger, we will mail to
   you a form with instructions for making your election of the form of
   consideration you prefer to receive and a letter of transmittal for
   surrendering your VoiceStream share certificates. This election is described
   beginning on page ____ in the Summary. To make an election, you will need to
   deliver the election form, the letter of transmittal and your VoiceStream
   share certificates to the escrow agent before the election deadline that we
   will announce in the future before the expected completion of the Deutsche
   Telekom/VoiceStream merger. It is important that you complete the election
   form when you receive it to make a timely election because stockholders who
   fail to do so will lose their right to make an election.

   Powertel Stockholders

   If you are a Powertel stockholder, then after Deutsche Telekom and Powertel
   complete the Deutsche Telekom/Powertel merger or VoiceStream and Powertel
   complete the VoiceStream/Powertel merger, as the case may be, we will send
   you instructions explaining how to exchange your Powertel share certificates.
   If the Deutsche Telekom/Powertel merger is completed, you will be entitled to
   exchange your Powertel share certificates for certificates representing
   Deutsche Telekom ADSs or Deutsche Telekom ordinary shares. If the
   VoiceStream/Powertel merger is completed, you will be entitled to exchange
   your Powertel share certificates for certificates representing VoiceStream
   common shares.

Q. HOW DO I VOTE?

A. You may choose one of the following ways to cast your vote:

   - by completing the accompanying proxy card and returning it in the enclosed
     postage-paid envelope;

   - through the Internet or by telephone, as explained on the accompanying
     proxy card; or

   - by appearing and voting in person at the VoiceStream special meeting, if
     you are a VoiceStream stockholder, or at the Powertel special meeting, if
     you are a Powertel stockholder.

   If your shares are held in "street name," which means that your shares are
   held in the name of a bank, broker or other financial institution instead of
   in your own name, you must either direct the financial institution as to how
   to vote your shares or obtain a proxy from the financial institution to vote
   at your special meeting.

</TABLE>

     VoiceStream stockholders who fail to make an election will be deemed to
have made the mixed election.

  EXAMPLES (SUBJECT TO PRORATION AND ADJUSTMENT)

     - Choosing the mixed election.  If you own 100 VoiceStream shares and you
       make the mixed election, you will receive $30 multiplied by 100, or
       $3,000 in cash, and 3.2 multiplied by 100, or 320 Deutsche Telekom
       shares.

                                        5
<PAGE>   24

     - Choosing the all-stock election.  If you own 100 VoiceStream shares and
       you make the all-stock election, you will receive 3.7647 multiplied by
       100, or 376 Deutsche Telekom shares. In addition, you will receive a cash
       payment equal to .47 of the market price of a Deutsche Telekom share in
       lieu of the remaining fractional share.

     - Choosing the all-cash election.  If you own 100 VoiceStream shares and
       you make the all-cash election, you will receive $200 multiplied by 100,
       or $20,000 in cash.

PRORATION, ADJUSTMENT AND ELECTION PROCEDURES OF THE DEUTSCHE
TELEKOM/VOICESTREAM MERGER (SEE PAGE __)

  PRORATION

     The total number of Deutsche Telekom shares that will be issued and the
total amount of cash that will be paid in the Deutsche Telekom/VoiceStream
merger is 3.2 and $30, respectively, times the total number of VoiceStream
common shares outstanding immediately prior to the completion of the Deutsche
Telekom/VoiceStream merger. Therefore, the all-stock and all-cash elections are
subject to proration to preserve these limitations on the number of Deutsche
Telekom shares to be issued and the amount of cash to be paid. As a result, even
if you elect to receive the all-stock or all-cash consideration, you may
nevertheless receive a mix of Deutsche Telekom shares and cash. VoiceStream
stockholders who make a mixed election will not be subject to the proration.

     Example 1:  If you make the all-stock election and too many other
VoiceStream stockholders make the all-stock election, then you and all
VoiceStream stockholders that elected to receive all Deutsche Telekom shares
will receive as many Deutsche Telekom shares as are available for this group
(after honoring all mixed elections and treating all non-electing shares as if a
mixed election had been made), on a proportionate basis, and the rest of your
consideration in cash.

     Example 2:  If you make the all-cash election and too many other
VoiceStream stockholders make the all-cash election, then you and all
VoiceStream stockholders who elected to receive all cash will receive as much
cash as is available for this group (after honoring all mixed elections and
treating all non-electing shares as if a mixed election had been made), on a
proportionate basis, and the rest of your consideration in Deutsche Telekom
shares.

  ADJUSTMENT

     All three types of election are subject to VoiceStream's obligation to
cause Deutsche Telekom to reduce the aggregate cash consideration received in
the Deutsche Telekom/VoiceStream merger to the extent necessary to preserve
tax-free treatment of the receipt of Deutsche Telekom shares by VoiceStream
stockholders for U.S. federal income tax purposes.

     The adjustment could occur if the average trading price of the Deutsche
Telekom ordinary shares during a measurement period close to the time of the
closing of Deutsche Telekom/VoiceStream merger is lower than ______ euros (or,
$______, when translated into U.S. dollars), but could occur at a higher trading
price depending on a number of other factors, including the exchange rate
between the euro and the U.S. dollar immediately before the closing of the
Deutsche Telekom/VoiceStream merger, the trading price of Deutsche Telekom
shares immediately before the closing of the Deutsche Telekom/VoiceStream
merger, the number of outstanding VoiceStream shares at the time of the Deutsche
Telekom/VoiceStream merger and the number of VoiceStream stockholders who
exercise dissenters' rights. If such an adjustment were made, you may receive
more Deutsche Telekom shares and less cash than you elected, even after giving
effect to proration. If such an adjustment is necessary, VoiceStream will
determine, in consultation with Deutsche Telekom, the amount by which the
aggregate cash consideration needs to be reduced. Deutsche Telekom will then
issue to VoiceStream stockholders that would receive a cash payment as part of
their Deutsche Telekom/VoiceStream merger consideration additional Deutsche
Telekom shares generally equal in value to the amount of the reduction in the
cash payment, based on a fixed exchange rate of one euro to 0.9216 U.S. dollars
and a calculated average price of the Deutsche Telekom shares during a
measurement period close to the time of the merger. If the calculated average
price of a Deutsche Telekom ordinary share in euros on the Frankfurt Stock
Exchange at the time of the reduction in the cash payment is 33 euros or less,
the value of a Deutsche Telekom share will be

                                        6
<PAGE>   25

deemed to be 33 euros for purposes of calculating the number of additional
Deutsche Telekom shares to be issued in respect of the reduction.

     Example:  If you own 100 VoiceStream common shares, made a mixed election
and therefore would have otherwise received $30 in cash per share as part of
your merger consideration, you would have received a total of $3,000 and 320
Deutsche Telekom shares, absent adjustment. If we adjust the cash payment by
reducing it from $30 to $25, you then would receive in lieu of the $500 (or $5
per VoiceStream share) that number of Deutsche Telekom shares equal in value to
$500 based on a calculated average price of the Deutsche Telekom ordinary shares
in euros on the Frankfurt Stock Exchange during a measurement period close to
the time the Deutsche Telecom/VoiceStream merger is completed, converted into
dollars at an exchange rate of one euro to 0.9216 U.S. dollars (with cash paid
in lieu of fractional shares). However, if the calculated average price would
otherwise be 33 euros or less, the price of a Deutsche Telekom ordinary share
will be deemed to be 33 euros for purposes of the calculation. In this example,
if the price of Deutsche Telekom shares is lower than 33 euros at the time of
the merger or if the euro depreciates from the fixed one euro to 0.9216 U.S.
dollar exchange rate at that time, the value of Deutsche Telekom shares you
receive generally would be less than the $500 value of the cash adjustment.

  FORM OF DEUTSCHE TELEKOM SHARES

     If you are a VoiceStream stockholder, you will receive Deutsche Telekom
shares in the form of Deutsche Telekom ADSs, which are principally traded on the
NYSE under the symbol "DT", or, if you elect, Deutsche Telekom ordinary shares,
which principally trade on the Frankfurt Stock Exchange under the symbol "DTE".
Each Deutsche Telekom ADS represents one Deutsche Telekom ordinary share.

  ELECTION PROCEDURES

     At least 45 days before the Deutsche Telekom/VoiceStream merger is expected
to be completed, we intend to mail to you a form with instructions for making
the all-stock election or the all-cash election or for receiving the mixed
consideration, and a letter of transmittal that you must properly complete and
deliver to the escrow agent with your VoiceStream share certificates before the
election deadline. If you fail to submit a properly completed election form
before the election deadline, you will be deemed to have made a mixed election
and will automatically receive for each of your VoiceStream shares $30 in cash
and 3.2 Deutsche Telekom shares, subject to adjustment, when you deliver to the
escrow agent your VoiceStream share certificates, together with a properly
completed letter of transmittal.

     The election deadline will be five business days before the Deutsche
Telekom/VoiceStream merger is expected to be completed. Since the actual
election deadline is not yet known, we intend to make a public announcement
notifying you of the election deadline at least five business days before that
deadline.

     If you own VoiceStream common shares in "street name" through a bank,
broker or other financial institution and wish to make an all-stock or all-cash
election, you should seek advice from the financial institution concerning
making such election.

INFORMATION ABOUT DEUTSCHE TELEKOM ADSs (SEE PAGE ____)

     A Deutsche Telekom ADS is an American depositary share that represents one
ordinary share of Deutsche Telekom. The Deutsche Telekom ADSs were created to
allow U.S. shareholders of Deutsche Telekom to more easily hold and trade
interests in Deutsche Telekom on U.S. markets. Citibank, N.A., the depositary
for the Deutsche Telekom ADSs, will issue the Deutsche Telekom ADSs you will
receive in the relevant merger, and Citibank AG, Frankfurt Branch, the custodian
for the Deutsche Telekom ADSs, will hold the Deutsche Telekom ordinary shares
represented by those ADSs on behalf of the depositary.

     There are advantages and disadvantages to receiving Deutsche Telekom ADSs
rather than Deutsche Telekom ordinary shares. Non-institutional holders of
VoiceStream common shares and Powertel shares may prefer to receive Deutsche
Telekom ADSs instead of Deutsche Telekom ordinary shares for the following
reasons:

     - dividends on Deutsche Telekom ADSs are paid in U.S. dollars, whereas
       dividends on Deutsche Telekom ordinary shares are paid in euros; and

     - Deutsche Telekom ADSs are traded in the United States on the NYSE,
       whereas Deutsche Telekom ordinary shares trade on the Frankfurt Stock
       Exchange and other non-U.S. exchanges, but do not trade on any U.S.
       national securities exchange.

     You should, however, be aware that the trading volume of the Deutsche
Telekom ordinary shares on the Frankfurt Stock Exchange historically has been
significantly greater than the trading volume of the Deutsche Telekom ADSs on
the NYSE. If this continues, it may be more advantageous for a holder to sell a
large number of Deutsche Telekom ordinary shares on the Frankfurt Stock Exchange
than to sell a large number of Deutsche Telekom ADSs on the NYSE. In addition,
various fees are payable by holders of Deutsche Telekom ADSs to the depositary
in connection with various transactions, including the deposit or withdrawal of
shares in exchange for the depositary receipts representing the ADSs.

     The rights of a holder of Deutsche Telekom ADSs also are different from the
rights of a holder of Deutsche Telekom ordinary shares with respect to various
other matters. We explain the differences in rights of holders of Deutsche
Telekom ADSs and Deutsche Telekom ordinary shares under "Description of Deutsche
Telekom American Depositary Shares" beginning on page ____ and under
"Description of Deutsche Telekom Ordinary Shares" beginning on page ____.

  ELECTION PROCEDURES

     In the Deutsche Telekom/VoiceStream merger and Deutsche Telekom/Powertel
merger, you will receive Deutsche Telekom ADSs for your VoiceStream common
shares or Powertel common and preferred shares, as the case may be, unless you
elect to receive Deutsche Telekom ordinary shares instead. You will receive
instructions for making this election with the letter of transmittal, which, if
you are a VoiceStream stockholder, will be sent to you at least 45 days prior to
the expected completion of the Deutsche Telekom/VoiceStream merger, or if you
are a Powertel stockholder, will be sent to you shortly after the completion of
the Deutsche Telekom/Powertel merger. If you own VoiceStream common shares or
Powertel common shares in "street name" through a bank, broker or other
financial institution, you should seek advice from the financial institution
concerning making an election to receive Deutsche Telekom ordinary shares.

  VOICESTREAM/POWERTEL MERGER

     We present below the per share closing prices for VoiceStream common shares
and Powertel common shares, each as reported on Nasdaq. These prices are
presented on the following dates:

     - August 25, 2000, the last trading day before the public announcement of
       the signing of the VoiceStream/Powertel merger agreement; and

     - __________, 2000, the latest practicable date before the printing of this
       document.

     In addition, the table below presents implied equivalent per share values
for Powertel common shares on August 25, 2000 and __________, 2000. Powertel
preferred shares are not publicly traded. Under the terms of the
VoiceStream/Powertel merger agreement, holders of Powertel common shares and
Powertel preferred shares (on an as-converted-to-common shares basis) will
receive VoiceStream common shares at a conversion ratio ranging from 0.65 to
0.75, to be determined as follows. If the average closing price of VoiceStream
common shares on 10 trading days randomly selected from the 20 trading-day
period ending five trading days before the completion of the
VoiceStream/Powertel merger is below $130.77 and above $113.33 per share, then
an exchange ratio calculated to yield $85 in VoiceStream common shares for each
Powertel common share equivalent will apply. If the average closing price of
VoiceStream common shares is $130.77 per share or above during the 10-day
trading period, then an exchange ratio of 0.65 of a VoiceStream common share per
Powertel common share equivalent will apply. If the average closing price of
VoiceStream common shares is $113.33 per share or below during the 10-day
trading period, then an exchange ratio of 0.75 of a VoiceStream common share per
Powertel common share equivalent will apply. The information presented in the
"Powertel share price equivalent" column assumes that the average closing price
of VoiceStream common shares for purposes of determining the exchange ratio is
equal to the closing price on August 25, 2000 and __________, 2000,

CURRENCIES AND EXCHANGE RATES

     References in this document to "dollars," "$" or "cents" are to the
currency of the U.S. and references to "euro" and "EUR" are to the currency of
the European Union.

     In this document, unless otherwise stated, euros have been translated,
solely for convenience, into U.S. dollars at the noon buying rate in New York
City for cable transfers in euros as certified for customs purposes by the
Federal Reserve Bank of New York on ____, 2000. At that date, the noon buying
rate for the euro was EUR ____ per U.S.$1.00, which, if expressed in Deutsche
Marks, would have been equivalent to a rate of DM ____ per U.S.$1.00, translated
from euros at the official fixed conversion rate. On __________, 2000, the
latest practicable date for which exchange rate information was available before
the printing of this document, the noon buying rate was $____ per one euro.
These translations should not be construed as a representation that the U.S.
dollar amounts actually represent, or could be converted into, euros at the
rates indicated.

     For a five-year history of relevant exchange rates, see "Exchange Rates" on
page ____.

                      SELECTED CONSOLIDATED FINANCIAL DATA

     We present below selected historical financial data of Deutsche Telekom,
VoiceStream and Powertel for the six months ended June 30, 2000 and 1999 and for
each of the years in the five year period ended December 31, 1999. We derived
the selected historical financial data as of and for the six month periods ended
June 30, 2000 and 1999 from the unaudited interim consolidated financial
statements of Deutsche Telekom, VoiceStream and Powertel for those periods,
including the notes thereto. We derived the selected historical financial data
as of and for each of the years in the five year period ended December 31, 1999
from the audited annual consolidated financial statements of Deutsche Telekom,
VoiceStream and Powertel, including the notes to those financial statements. All
the data should be read in conjunction with the consolidated financial
statements and notes thereto, of Deutsche Telekom, VoiceStream and Powertel
incorporated by reference. See "-- Where You Can Find More Information."

     VoiceStream and Powertel report their financial information in accordance
with U.S. GAAP. Deutsche Telekom reports its financial statements in accordance
with German GAAP. German GAAP differs in certain significant respects from U.S.
GAAP. For a discussion of the principal differences between German GAAP and U.S.
GAAP as they relate to Deutsche Telekom, see Note 36 to Deutsche Telekom's
audited annual consolidated financial statements. Deutsche Telekom historically
has applied U.S. GAAP accounting principles to the extent allowable under German
GAAP. Deutsche Telekom has decided that, in preparing its German GAAP financial
statements, it will generally apply accounting and valuation principles in line
with those of U.S. GAAP. However, Deutsche Telekom may depart from this approach
when it determines that U.S. GAAP treatment would likely be contrary to the
general understanding of investors in Germany. Any such departures are reflected
in Deutsche Telekom's U.S. GAAP reconciliation footnote.

 (3) Since the beginning of the 1999 financial year, revenues have been reported
     in line with the changed organizational structure of group business areas
     of the Deutsche Telekom Group. The prior year figures have been restated to
     reflect the new structure. The difference in the figures compared to those
     stated in prior years is mainly attributable to the deduction of the
     revenues from the billing of services of other network operators, amounting
     to approximately 0.5 billion euros, which were previously shown under other
     services expense.

 (4) In 1995, the amount includes pro-forma value-added tax. Adjusted to exclude
     VAT, revenue would have been 30.5 billion euros.

 (5) In 1996, the amount includes one-time value-added tax refund amounting to
     338 million euros.

 (6) Including, for periods after 1995, depreciation of value-added tax
     capitalized prior to January 1, 1996.

 (7) In 1995, the levy to the Federal Republic was paid for the last time, with
     Deutsche Telekom becoming essentially exempt from this levy. Since January
     1, 1996, Deutsche Telekom has been subject to normal corporate taxation.

 (8) For convenience purposes, the selected financial data, as of June 30, 2000
     and December 31, 1999, has been converted from euros to United States
     dollars at a period end exchange rate of 0.9575 and 1.0028, respectively.

 (9) For convenience purposes, the selected financial data for the six months
     ended June 30, 2000 and the year ended December 31, 1999 have been
     converted from euros to United States dollars at an average exchange rate
     of 0.9592 and 1.0652, respectively.

(10) As of and prior to June 30, 2000, Deutsche Telekom did not have any
     potentially dilutive securities outstanding. Accordingly, there was no
     difference between basic and diluted earnings per share for U.S. GAAP
     purposes.

(11) EBITDA, under German GAAP, represents the operating income before net
     interest, taxation, depreciation and amortization, net income (loss)
     related to equity investments, and write-downs on financial assets and
     marketable securities. EBITDA should not be considered in isolation as an
     alternative to net income, operating income or any other measure of
     performance under German or U.S. GAAP. Management believes EBITDA is a
     relevant measurement utilized by the telecommunication industry to assess
     performance which attempts to eliminate variances caused by the effects of
     differences in taxation, the amount and types of capital employed and
     depreciation and amortization policies. EBITDA also provides meaningful
     additional information about the company's 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, Deutsche Telekom's presentation may not be
     comparable to other similarly titled measures of other companies.

(1) Represents population that is covered by VoiceStream's network, excluding
    unconsolidated affiliates.

(2) Adjusted EBITDA represents operating loss before depreciation and
    amortization and non-cash stock based compensation. VoiceStream's management
    believes adjusted EBITDA provides meaningful additional information on
    VoiceStream's operating results and on its ability to service its long-term
    debt and other fixed obligations and to fund its continuing growth. Adjusted
    EBITDA is considered by many financial analysts to be a meaningful indicator
    of an entity's ability to meet its future financial obligations, and growth
    in adjusted EBITDA is considered to be an indicator of future profitability,
    especially in a capital-intensive industry such as wireless telecommuni-
    cations. Adjusted EBITDA should not be construed as an alternative to
    operating income (loss) as determined in accordance with U.S. GAAP, as an
    alternate to cash flows from operating activities, as determined in
    accordance with U.S. GAAP, or as a measure of liquidity. Because adjusted
    EBITDA is not calculated in the same manner by all companies, VoiceStream's
    presentation may not be comparable to other similarly titled measures of
    other companies.

(1) During the year ended December 31, 1999, Powertel sold substantially all of
    its remaining cellular telephone assets for $89.3 million and 650 of its
    wireless towers for $274.6 million, resulting in an aggregate gain of $129.2
    million. During the year ended December 31, 1997, Powertel sold
    substantially all of its cellular telephone assets in the state of Maine for
    $77.2 million, resulting in a gain of $41.9 million.

(2) During 1996, Powertel changed its method of accounting for costs incurred in
    connection with certain promotional programs under which customers receive
    discounted cellular equipment or airtime usage credits. Under Powertel's
    previous accounting method, all such costs were deferred and amortized over
    the life of the related non-cancelable cellular telephone service agreement.
    Under the new accounting method, the costs are expensed as incurred.

(3) EBITDA represents operating (loss) income before depreciation and
    amortization. EBITDA is provided because it is a measure commonly used in
    the industry. EBITDA is not a measurement of financial performance under
    U.S. GAAP and should not be considered an alternative to net income as a
    measure of performance or to cash flow as a measure of liquidity.

(1) Pro forma EBITDA, under German GAAP, represents the pro forma operating
    income before net interest, taxation, depreciation and amortization, net
    income (loss) from equity investments, and write-downs on financial assets
    and marketable securities. Pro forma EBITDA should not be considered in
    isolation as an alternative to net income, operating income or any other
    measure of performance under German or U.S. GAAP. Management believes EBITDA
    is a relevant measurement utilized by the telecommunication industry to
    assess performance which attempts to eliminate variances caused by the
    effects of differences in taxation, the amount and types of capital employed
    and depreciation and amortization policies. Pro forma EBITDA also provides
    meaningful additional information about the Company's operating results and
    on its ability to service its long-term debt and other fixed obligations and
    to fund its continuing growth. Because Pro forma EBITDA is not calculated in
    the same manner by all companies, Deutsche Telekom's presentation may not be
    comparable to other similarly titled measures of other companies.

            ENFORCEABILITY OF CIVIL LIABILITY AND SERVICE OF PROCESS

     Deutsche Telekom is incorporated under the laws of the Federal Republic of
Germany, and all of the members of the Deutsche Telekom management board,
executive officers and certain of the experts named or referred to herein are
non-residents of the United States. A substantial majority of the assets of
Deutsche Telekom and its direct and indirect subsidiaries and such non-resident
persons are located outside the United States. As a result, it may not be
possible for investors to effect service of process within the United States
upon such persons or to enforce in U.S. courts judgments against such persons
and judgments of such courts predicated upon the civil liability provisions of
the U.S. federal securities laws. Deutsche Telekom has been advised by Hengeler
Mueller Weitzel Wirtz, its German legal counsel, that there is doubt as to the
enforceability in Germany, in original actions or actions for enforcement of
judgments of U.S. courts, of claims based solely upon U.S. federal securities
laws.

    RISK FACTORS RELATING TO THE DEUTSCHE TELEKOM/VOICESTREAM MERGER AND THE
                        DEUTSCHE TELEKOM/POWERTEL MERGER

THE VALUE OF DEUTSCHE TELEKOM ADSs AND DEUTSCHE TELEKOM ORDINARY SHARES TO BE
RECEIVED MAY FLUCTUATE CONSIDERABLY

     If you are a VoiceStream stockholder, the number of Deutsche Telekom ADSs
or Deutsche Telekom ordinary shares that you will receive in the Deutsche
Telekom/VoiceStream merger for each VoiceStream common share is fixed at 3.2 if
you receive the mixed consideration and at 3.7647 if you receive the all-stock
consideration, subject to proration and adjustment. If you are a Powertel
stockholder, the number of Deutsche Telekom ADSs or Deutsche Telekom ordinary
shares that you will receive in the Deutsche Telekom/Powertel merger is fixed at
2.6353 for each Powertel common share, 121.9294 for each Powertel Series A and
Series B preferred share, 93.0106 for each Powertel Series D preferred share and
179.5979 for each Powertel Series E and Series F preferred share, plus dividends
thereon, subject to certain adjustments. Neither the Deutsche
Telekom/VoiceStream merger agreement nor the Deutsche Telekom/ Powertel merger
agreement contains a mechanism to adjust the exchange ratios in the event that
the market price of the Deutsche Telekom ADSs or Deutsche Telekom ordinary
shares declines. Therefore, because the market prices of Deutsche Telekom ADSs
and Deutsche Telekom ordinary shares may fluctuate, the value of the
consideration to be received by VoiceStream stockholders and Powertel
stockholders at the time of the Deutsche Telekom/VoiceStream merger and the
Deutsche Telekom/ Powertel merger, respectively, will depend on the market
prices at that time. The market prices of Deutsche Telekom ADSs and Deutsche
Telekom ordinary shares at the completion of the Deutsche Telekom/VoiceStream
merger and the Deutsche Telekom/Powertel merger may vary from their respective
market prices on the respective dates of the Deutsche Telekom/VoiceStream merger
agreement and the Deutsche Telekom/Powertel merger agreement (when the
respective exchange ratios were set), the date of this proxy
statement/prospectus and the dates of the VoiceStream special meeting and the
Powertel special meeting, respectively. These variances may be due to a number
of factors, including:

     - changes in the business, operations or prospects of Deutsche Telekom,
       VoiceStream or Powertel;

     - market assessments of the likelihood of completion and timing of the
       Deutsche Telekom/ VoiceStream merger and the Deutsche Telekom/Powertel
       merger;

     - the effect of any conditions or restrictions imposed on or proposed with
       respect to the combined company by regulatory agencies due to the
       Deutsche Telekom/VoiceStream merger or the Deutsche Telekom/Powertel
       merger;

     - general market and economic conditions and other factors; and

     - the prospects of post-merger operations.

     Furthermore, there may be a substantial period of time between the time
stockholder approval is received and the time the mergers are completed.

     VoiceStream has the right to terminate the Deutsche Telekom/VoiceStream
merger agreement if the average price of Deutsche Telekom ordinary shares to be
used in any tax-related adjustment to the amount of the cash merger
consideration in the Deutsche Telekom/VoiceStream merger, as calculated close to
the time that merger is completed, is less than 33 euros. The average price of
Deutsche Telekom ordinary shares to be used in any adjustment, if necessary,
will be calculated by taking the average trading price of those shares on the
Frankfurt Stock Exchange on seven trading days randomly selected from the 15
trading days immediately preceding the date on which any adjustment
determination is to be made, which will be very close to the time the merger is
completed. We cannot assure you that even if the Deutsche Telekom ordinary share
price reaches this level, VoiceStream will terminate the Deutsche Telekom/
VoiceStream merger agreement. In this circumstance, the market price of any
Deutsche Telekom ordinary shares that you receive as a VoiceStream stockholder
will be less than 33 euros per Deutsche Telekom share. Although the Deutsche
Telekom/Powertel merger agreement will terminate if the Deutsche
Telekom/VoiceStream merger agreement is terminated under the circumstances
described in this
                                       35
<PAGE>   54

paragraph or otherwise, neither Powertel nor the Powertel board of directors has
any right to cause the VoiceStream board of directors to invoke or waive any of
VoiceStream's termination rights at any time.

     In addition, the stock market has experienced significant price and volume
fluctuations. These stock market fluctuations could have a material adverse
effect on the market prices of the Deutsche Telekom ADSs and Deutsche Telekom
ordinary shares before the Deutsche Telekom/VoiceStream merger and the Deutsche
Telekom/Powertel merger are completed and could occur after stockholder approval
is obtained and before completion.

     Accordingly, as a result of the fixed exchange ratios in the Deutsche
Telekom/VoiceStream merger and the Deutsche Telekom/Powertel merger, you may
receive Deutsche Telekom ADSs or Deutsche Telekom ordinary shares in the
Deutsche Telekom/VoiceStream merger or the Deutsche Telekom/Powertel merger, as
applicable, that are worth less at the completion of the applicable merger or on
the date of the VoiceStream special meeting or the Powertel special meeting, as
applicable, than on the date of this document. Any decrease in the market prices
of Deutsche Telekom ADSs and Deutsche Telekom ordinary shares before the
completion of the Deutsche Telekom/VoiceStream merger and the Deutsche
Telekom/Powertel merger will directly reduce the value of the stock portion of
the merger consideration received by VoiceStream stockholders in the Deutsche
Telekom/VoiceStream merger and by the Powertel stockholders in the Deutsche
Telekom/Powertel merger. Many of the factors causing fluctuations in the market
prices of Deutsche Telekom ADSs and Deutsche Telekom ordinary shares, as
discussed above, are beyond our control.

VOICESTREAM STOCKHOLDERS MAY RECEIVE DIFFERENT CONSIDERATION FROM WHAT THEY
ELECT

     The consideration to be received by the VoiceStream stockholders in the
Deutsche Telekom/VoiceStream merger is subject to proration to preserve the
limitations on the maximum amount of cash and Deutsche Telekom shares to be
issued in the Deutsche Telekom/VoiceStream merger. Further, the total amount of
cash to be paid may be reduced and replaced with Deutsche Telekom shares if
necessary to preserve beneficial U.S. tax treatment. Furthermore, if the total
amount of cash to be paid is reduced and replaced with Deutsche Telekom shares
to preserve beneficial tax treatment, the value of the Deutsche Telekom shares
delivered to VoiceStream stockholders in replacement of the cash may be less
than the cash amount it replaces.

     Accordingly, holders of VoiceStream common shares may not receive the type
of consideration they elect to receive in the Deutsche Telekom/VoiceStream
merger. If a holder of VoiceStream common shares elects to receive all of the
merger consideration in cash and the cash portion is oversubscribed, then the
holder will receive a portion of the Deutsche Telekom/VoiceStream merger
consideration in Deutsche Telekom shares. Similarly, if a holder elects to
receive all of the merger consideration in Deutsche Telekom shares and the
Deutsche Telekom share portion is oversubscribed, then the holder will receive a
portion of the Deutsche Telekom/VoiceStream merger consideration in cash.
Further, in all cases, if the amount of cash is reduced as a result of the tax
adjustment, holders (including those making a mixed election) may receive more
Deutsche Telekom shares than they elected even after accounting for proration
and such additional Deutsche Telekom shares may have a value that is less than
the amount of the cash that it replaces. In addition, because the receipt of
cash in the Deutsche Telekom/VoiceStream merger may be taxable to a VoiceStream
stockholder, no assurance can be given that any VoiceStream stockholder can
exchange VoiceStream common shares in an entirely tax-free transaction. The
proration and tax adjustment procedures are described in greater detail under
"Summary of the Deutsche Telekom/VoiceStream Transaction Documents -- The
Deutsche Telekom/VoiceStream Merger Agreement -- Consideration to be Received in
the Deutsche Telekom/VoiceStream Merger."

THE MERGER CONSIDERATION THAT POWERTEL STOCKHOLDERS MAY RECEIVE MAY BE ADJUSTED
DOWNWARD

     The consideration to be received by the Powertel stockholders in the
Deutsche Telekom/Powertel merger is subject to a downward pro-rata adjustment if
the aggregate number of Powertel common shares outstanding as of the completion
of the Deutsche Telekom/Powertel merger on a fully diluted basis,

                                       36
<PAGE>   55

including Powertel common shares issuable in connection with existing
commitments to sell or issue Powertel common shares and securities convertible
into Powertel common shares (an amount we call the "adjusted fully diluted
shares amount"), exceeds a specified amount of shares. The conversion ratio
related to each Powertel common share and Powertel preferred share will be
adjusted downward to the extent the adjusted fully diluted shares amount exceeds
a specified amount of shares and, in the event of such an adjustment, Powertel
stockholders will receive fewer Deutsche Telekom shares for each Powertel share
they own. The adjustment procedures are described in greater detail under
"Summary of Deutsche Telekom/Powertel and VoiceStream/Powertel Transaction
Documents -- The Deutsche Telekom/Powertel Merger Agreement -- Consideration to
be Received in the Deutsche Telekom/Powertel Merger."

FORWARD-LOOKING STATEMENTS REGARDING BUSINESS AND OPERATIONS OF THE COMBINED
COMPANY MAY PROVE INACCURATE

     Deutsche Telekom, VoiceStream and Powertel have made forward-looking
statements in this document and in documents incorporated by reference into this
document concerning financial projections and estimates and their underlying
assumptions; statements regarding plans, objectives and expectations with
respect to future operations, products and services; the impact of regulatory
initiatives on their operations; their share of new and existing markets;
general industry and macroeconomic growth rates and their performance relative
to those growth rates and statements regarding future performance. Forward-
looking statements are generally identified by the words "expects",
"anticipates", "believes", "intends", "estimates" and similar expressions.

     The forward-looking statements are subject to various risks and
uncertainties, most of which are difficult to predict and are generally beyond
our control. The actual results, performances or achievements of Deutsche
Telekom, VoiceStream, Powertel or the combined company could differ
significantly from those expressed in, or implied by, the forward-looking
statements made in or incorporated by reference into this document. Accordingly,
we cannot assure you that any of the events anticipated by the forward-looking
statements will occur, or, if they do, what impact they will have on the results
of operations and financial condition of Deutsche Telekom following the Deutsche
Telekom/VoiceStream merger or following the Deutsche Telekom/VoiceStream and
Deutsche Telekom/Powertel mergers.

REGULATORS MAY IMPOSE CONDITIONS THAT REDUCE THE ANTICIPATED BENEFITS FROM THE
MERGERS AND ADVERSELY AFFECT THE PRICE OF THE DEUTSCHE TELEKOM ADSs AND DEUTSCHE
TELEKOM ORDINARY SHARES

     As a condition to our respective obligations to complete the Deutsche
Telekom/VoiceStream merger and the Deutsche Telekom/Powertel merger, we must
obtain the approval of various regulatory authorities, including the FCC, the
Committee on Foreign Investment and, in the case of the Deutsche Telekom/
Powertel merger, either the FTC or the Antitrust Division of the DOJ. Any of
these entities could impose conditions or restrictions on their approvals and we
cannot assure you that these approvals will be obtained without materially
adverse conditions or restrictions.

     The Deutsche Telekom/VoiceStream merger may be terminated in the event that
the conditions or restrictions imposed by the regulatory authorities are
materially adverse to Deutsche Telekom or its mobile telecommunications
business, in each case, assuming that the Deutsche Telekom/VoiceStream merger
had been completed, and assuming that any other acquisition in the mobile
telecommunications industry entered into or completed by Deutsche Telekom after
July 23, 2000 had been completed.

     The Deutsche Telekom/Powertel merger may be terminated in the event that
the conditions or restrictions imposed by the regulatory authorities would
reasonably be expected to have a material adverse effect on Deutsche Telekom (in
the case of termination by Powertel) or on Deutsche Telekom or Powertel (in the
case of termination by Deutsche Telekom) or the transactions contemplated by the
Deutsche Telekom/Powertel merger agreement. In addition, under the Deutsche
Telekom/Powertel merger agreement, Deutsche Telekom is permitted to terminate
the Deutsche Telekom/Powertel merger agreement if Deutsche Telekom, Powertel,
VoiceStream or any of their subsidiaries were to be required, in connection with
the grant of any required regulatory approval or order, to divest or hold
separate or

                                       37
<PAGE>   56

otherwise take or commit to take any action that limits Deutsche Telekom's
freedom of action with respect to Deutsche Telekom, Powertel, VoiceStream or any
of their subsidiaries or any material portion of the assets of Deutsche Telekom,
Powertel, VoiceStream or any of their subsidiaries or any of the business,
product lines or assets of Deutsche Telekom, Powertel, VoiceStream or any of
their subsidiaries and such approval or order shall have become final and
nonappealable.

     However, even if these conditions or restrictions are imposed, we cannot
assure you that we will terminate the Deutsche Telekom/VoiceStream merger
agreement or the Deutsche Telekom/Powertel merger agreement, as the case may be,
or that we will not waive conditions to the completion of the mergers or not
take actions that we are not required to take under the Deutsche
Telekom/Powertel merger agreement. If we were to proceed with the Deutsche
Telekom/VoiceStream merger or the Deutsche Telekom/Powertel merger despite the
imposition of these conditions or restrictions, or should we take such actions,
we cannot assure you that there would be no material adverse effect on Deutsche
Telekom and the price of the Deutsche Telekom ADSs and Deutsche Telekom ordinary
shares.

INCREASED SALES VOLUME OF THE VOICESTREAM COMMON SHARES, POWERTEL COMMON SHARES
AND DEUTSCHE TELEKOM ADSs AND DEUTSCHE TELEKOM ORDINARY SHARES MAY ADVERSELY
AFFECT THE MARKET PRICE FOR THE DEUTSCHE TELEKOM ADSs AND DEUTSCHE TELEKOM
ORDINARY SHARES

     For a number of reasons, including those described below, stockholders of
VoiceStream or Powertel may sell a significant number of VoiceStream common
shares or Powertel common shares, or Deutsche Telekom ADSs or Deutsche Telekom
ordinary shares that they will receive in the mergers, and Deutsche Telekom's
two largest shareholders may sell a substantial amount of Deutsche Telekom
ordinary shares that they currently hold. Any of these sales could affect the
market price of the Deutsche Telekom ADSs or Deutsche Telekom ordinary shares.
These reasons include:

     - some U.S. mutual funds, state pension funds and other investors are not
       permitted to hold equity securities of non-U.S. companies;

     - some mutual funds and other investors hold shares of VoiceStream because
       it is included in the Nasdaq 100 Index, but Deutsche Telekom shares are
       not included in that index; and

     - the Federal Republic of Germany has publicly stated its intention to
       reduce substantially its ownership of Deutsche Telekom shares. The
       Federal Republic and a development bank that is 80% owned by the Federal
       Republic currently own in the aggregate approximately 58.2% of Deutsche
       Telekom's shares.

     As we discussed above, VoiceStream stockholders who as of the VoiceStream
record date beneficially owned approximately ____% of the outstanding
VoiceStream common shares have agreed to restrictions on the transfer of the
Deutsche Telekom ADSs and Deutsche Telekom ordinary shares that they will
receive in the Deutsche Telekom/VoiceStream merger. Also, stockholders who as of
the Powertel record date beneficially owned approximately ____% of the
outstanding Powertel common shares and all the outstanding Powertel preferred
shares have agreed to restrictions on the transfer of the Deutsche Telekom ADSs
and Deutsche Telekom ordinary shares that they will receive in the Deutsche
Telekom/Powertel merger. These restrictions cease to apply to a significant
portion of those shares three months after completion of the Deutsche
Telekom/VoiceStream merger or the Deutsche Telekom/Powertel merger and to all
the shares six months after completion of the Deutsche Telekom/VoiceStream
merger or the Deutsche Telekom/Powertel merger, respectively, and those
shareholders may seek to dispose of Deutsche Telekom ADSs or Deutsche Telekom
ordinary shares at that time.

            RISK FACTORS RELATING TO THE VOICESTREAM/POWERTEL MERGER

THE VALUE OF VOICESTREAM COMMON SHARES TO BE RECEIVED IN THE
VOICESTREAM/POWERTEL MERGER MAY FLUCTUATE CONSIDERABLY

     The number of VoiceStream common shares that you will receive in the
VoiceStream/Powertel merger for each of your Powertel common share equivalents
is calculated at a conversion rate of .65 if the average closing price of
VoiceStream common shares is $130.77 per share or above, or .75 if the average
closing price of VoiceStream common shares is $113.33 per share or below.
Between these two points, the ratio adjusts to yield $85 in VoiceStream common
shares for each Powertel common share equivalent. The average closing price of
VoiceStream common shares will be calculated by averaging the closing prices on
10 trading days randomly selected from the 20-trading day period ending five
trading days before the completion of the VoiceStream/Powertel merger. The stock
market experiences significant price and volume fluctuations that could have a
material adverse effect on the market prices of the VoiceStream common shares.
Because the market price of VoiceStream common shares may fluctuate, the value
at the time of the VoiceStream/Powertel merger of the consideration to be
received by Powertel stockholders will depend on the closing prices of
VoiceStream common shares during the selected 10 trading days and could be less
than $85 in market value for each Powertel common share equivalent.

VOICESTREAM WILL BE HIGHLY LEVERAGED, WHICH MAY LIMIT VOICESTREAM'S ABILITY TO
BORROW ADDITIONAL FUNDS TO MEET VOICESTREAM'S CAPITAL REQUIREMENTS

     VoiceStream's level of debt could affect VoiceStream's ability to build out
its systems and develop new systems. VoiceStream may have to incur further debt
if the $265 million credit facility between Powertel and certain lenders, dated
February 6, 1998, becomes due and payable prior to its stated maturity and
cannot be renegotiated on terms similar to existing ones. Without sufficient
funds, VoiceStream may have to delay or abandon some or all of VoiceStream's
plans to participate in upcoming FCC license auctions and/or its planned
build-out, which could materially limit VoiceStream's ability to compete in the
wireless telecommunications industry. VoiceStream's level of debt and the
incurrence of additional debt could have other consequences, such as requiring
VoiceStream to dedicate a greater portion of its cash flow from operations to
paying principal and interest and limiting its flexibility to react
competitively to changes in the wireless telecommunications industry.

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

     VoiceStream and Powertel compete with providers of PCS, cellular and other
wireless telecommunications services. Under the current rules of the FCC, up to
six PCS licensees and two cellular licensees, as well as digital specialized
mobile radio licensees, may operate in each geographic area. Proposed or future
rules may increase the number of licenses available. With so many companies
targeting many of the same customers, competition is intense. VoiceStream and
Powertel compete against AT&T Wireless Services, Inc., Verizon Wireless Inc.,
Nextel Communications, Inc., SBC Communications, Sprint Corp. (PCS Group) and US
West Wireless LLC, among others. Many of these competitors have substantially
greater financial resources than VoiceStream or Powertel, and several operate in
multiple segments of the industry. AT&T Wireless, Nextel and Sprint PCS operate
substantially nationwide networks and Verizon, among others, through joint
ventures and affiliation arrangements, operates or plans to operate
substantially nationwide wireless systems throughout the continental United
States. As a result of such competition, we cannot assure you that after the
VoiceStream/Powertel merger, the combined company will be able to successfully
attract and retain customers and grow its subscriber base and revenues.

                                       39
<PAGE>   58

VOICESTREAM AND POWERTEL EACH HAVE SUBSTANTIAL OPERATING LOSSES AND NEGATIVE
CASH FLOW AND VOICESTREAM MAY NOT BECOME PROFITABLE FOLLOWING THE
VOICESTREAM/POWERTEL MERGER

     VoiceStream sustained operating losses of approximately $____ million for
the nine months ended September 30, 2000, and $____ million in fiscal 1999,
$____ million in fiscal 1998 and $____ million in fiscal 1997. At September 30,
2000, VoiceStream had an accumulated deficit of $____ million and equity, net of
accumulated deficit, of $____ million. Powertel sustained operating losses of
approximately $____ million for the nine months ended September 30, 2000, and
$____ million in fiscal 1999, $____ million in fiscal 1998 and $____ million in
fiscal 1997. At September 30, 2000, Powertel had an accumulated deficit of $____
and negative equity, net of accumulated deficit, of $____.

     VoiceStream 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.
We cannot assure you that after the VoiceStream/Powertel merger VoiceStream will
achieve or sustain profitability or positive cash flow from operating activities
in the future or that VoiceStream will generate sufficient cash flow to service
current or future debt requirements.

THERE IS A RISK THAT VOICESTREAM'S EXPANSION WILL BE CONSTRAINED BECAUSE ITS
ABILITY TO EXPAND AND PROVIDE SERVICE NATIONALLY IS LIMITED BY ITS ABILITY TO
OBTAIN FCC LICENSES

     VoiceStream and Powertel each obtained licenses for markets in FCC auctions
or from the winning bidders or their successors, but even combined the two
companies do not have licenses covering the entire United States. VoiceStream's
and Powertel's ability to expand is limited to those markets where they have
obtained or can obtain licenses with sufficient spectrum to provide PCS service,
or where they economically can become resellers of service. Because there are a
limited number of licenses available, and because resale agreements require
mutual consent of the incumbent PCS license holders, there is a risk that they
may not be able to obtain the licenses they need for expansion.

VOICESTREAM AND POWERTEL ARE AT RISK OF LOSING COVERAGE IN CERTAIN MARKETS
BECAUSE THEY HAVE ENTERED INTO JOINT VENTURES THAT THEY DO NOT CONTROL IN AN
ATTEMPT TO EXPAND INTO THOSE MARKETS

     When implementing the PCS licensing scheme in the United States, the FCC
adopted rules that granted a narrow category of entities the right to bid for
and own C and F Block licenses. (Recently, the FCC has removed eligibility
restrictions for certain licenses in future entrepreneur auctions and has
allowed for the assignment or transfer of control of all C and F Block licenses
to a non-designated entity upon satisfaction of the first construction
benchmark.) VoiceStream did not qualify to obtain C and F Block licenses. In
order to continue expansion of service to VoiceStream customers, VoiceStream
obtained 49.9% minority interests in four joint ventures controlled by Cook
Inlet Region, Inc., each of which qualified to obtain licenses that VoiceStream
could not directly obtain. Through reseller and other contractual arrangements
between VoiceStream and the four joint ventures, VoiceStream customers are able
to obtain service in the ventures' territories. In all markets where the joint
ventures operate, VoiceStream is at risk because Cook Inlet is in control and
can choose to operate independently of VoiceStream. If these joint venture
entities determine to operate independently, VoiceStream's ability to compete on
a national scale may be adversely affected.

     Like VoiceStream, Powertel did not qualify to obtain C and F Block
licenses. In order to continue expansion of service to Powertel customers,
Powertel will obtain a 49.9% minority interest in Eliska Wireless Ventures I,
Inc., which is controlled by Eliska Wireless Investors and is qualified to hold
licenses that Powertel could not directly obtain. Eliska Wireless Ventures I,
Inc. does not currently hold any licenses but has contractual rights to acquire
C and F Block licenses from DiGiPH PCS, Inc. Powertel also has a creditor
relationship with Eliska Wireless, Inc., which itself holds two designated
entity licenses. It is anticipated that Powertel customers, through reseller,
roaming or other contractual arrangements between Powertel and the Eliska
entities, will be able to obtain service in the Eliska entities' markets. In all
markets where the Eliska entities operate (or will operate following the
acquisition of DiGiPH's licenses), Powertel is at risk because the Eliska
entities are in control and can choose to operate

                                       40
<PAGE>   59

independently of Powertel. If these entities choose to operate independently,
Powertel's ability to compete on a regional scale and VoiceStream's ability,
following completion of the merger with Powertel, to compete on a national scale
may be adversely affected.

THE FCC AND OTHER REGULATORY AGENCIES MUST APPROVE THE VOICESTREAM/POWERTEL
MERGER AND COULD DELAY OR REFUSE TO APPROVE THE VOICESTREAM/POWERTEL MERGER OR
IMPOSE CONDITIONS THAT COULD ADVERSELY AFFECT OUR BUSINESS OR FINANCIAL
CONDITION

     The Communications Act and FCC rules require the FCC's prior approval of
the transfer of control of Powertel's PCS licenses to VoiceStream. Completion of
the VoiceStream/Powertel merger is conditioned, among other factors, upon grants
of the requisite FCC consents 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
VoiceStream/Powertel 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 the board of directors of
VoiceStream, in the exercise of its business judgment, without seeking
stockholder approval, may waive finality as a condition of closing, we cannot
assure you that they will do so.

     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.
Conditions imposed on any licenses granted or delays in granting of the licenses
could impair the value of the licenses and reduce the value of our stock, and
could lead to our inability to obtain financing necessary for our growth. If we
are denied a license in a market we will not be able to operate in that market
unless we obtain another license or acquire a new license for that market.

THERE IS A RISK THAT THE JOINT VENTURE ENTITIES IN WHICH VOICESTREAM HOLDS
INTERESTS COULD LOSE LICENSES AS A RESULT OF COURT PROCEEDINGS

     All of the C Block licenses held by Cook Inlet entities could be affected
by U.S. AirWaves, Inc. v. FCC, which is pending in the U.S. Court of Appeals for
the D.C. Circuit. U.S. AirWaves participated in the original C Block auction,
which concluded on May 6, 1996, but withdrew after the bids exceeded the maximum
prices it was willing to pay. U.S. AirWaves is now seeking judicial review of
two orders in the FCC's rulemaking proceeding on payment financing for PCS
licenses: the Second Report and Order and the Order on Reconsideration of the
Second Report and Order (WT Docket No. 97-82). Since these orders enabled
initial C Block licenses to return licenses or modify the conditions of payment,
there is a remote threat that if the orders are reversed, affected licenses
could be returned to the Commission for reauction. The court consolidated into
this case similar petitions filed by several other parties. The case remains
pending.

     Additionally, 14 C Block licenses won by Cook Inlet/VoiceStream PCS LLC and
11 C Block licenses won by Omnipoint and subsequently assigned to joint ventures
controlled by Cook Inlet were issued subject to the outcome of the bankruptcy
proceeding of the original licensee, a subsidiary of Pocket Communications,
Inc., which was conditionally granted 43 C Block licenses in 1996. Pursuant to
an FCC order, the bankruptcy debtors elected to relinquish certain licenses,
which subsequently were reauctioned, and the bankruptcy court issued an order
making the election effective. A group of secured creditors of the debtors filed
with the court a motion for reconsideration of the election order. The motion
was denied, and the secured creditors appealed the denial to the United States
District Court for the District of Maryland, Northern Division. Because the
appeal of the election order is still pending, there is uncertainty as to the
referenced C Block licenses of the Cook Inlet entities. The District Court could
order the return of these licenses to the jurisdiction of the bankruptcy court.
In the event that these licenses are so returned, it is unlikely that the Cook
Inlet entities will be able to recoup any or all of the costs incurred by them
in connection with the construction and development of systems related to such
licenses.

                                       41
<PAGE>   60

     Loss of any license by any Cook Inlet entity will reduce or eliminate
VoiceStream's ability to own interests in markets where the licenses are lost,
thereby reducing VoiceStream's ability to compete with other national
competitors.

CONCERNS OVER RADIO FREQUENCY EMISSIONS OR OTHER HEALTH AND SAFETY RISKS MAY
DISCOURAGE USE OF WIRELESS SERVICES AND ADVERSELY AFFECT OUR BUSINESS

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

     Negative findings of studies concerning health and safety risks of wireless
handsets could have an adverse effect on the wireless industry, our business, or
the use of GSM technology. Such findings could lead to governmental regulations
that may have an adverse effect on our business. Several states have proposed or
enacted legislation which would limit or prohibit the use and/or possession of a
mobile telephone while driving an automobile. If legislation is adopted and
strictly enforced, it may have an adverse effect on our business.

                           FORWARD-LOOKING STATEMENTS

     This proxy statement/prospectus, and the documents we are incorporating by
reference, contain forward-looking statements about Deutsche Telekom,
VoiceStream, Powertel and the combined companies, which we intend to be covered
by the safe harbor for "forward-looking statements" provided by the Private
Securities Litigation Reform Act of 1995. Any document we filed or will file
with the SEC also may include forward-looking statements. Other written or oral
forward-looking statements have been made and may in the future be made, from
time to time, by or on behalf of Deutsche Telekom, VoiceStream and Powertel.
Forward-looking statements are statements that are not historical facts, and
include financial projections and estimates and their underlying assumptions;
statements regarding plans, objectives and expectations with respect to future
operations, products and services; the impact of regulatory initiatives on our
operations; our share of new and existing markets; general industry and
macroeconomic growth rates and our performance relative to them and statements
regarding future performance. Forward-looking statements generally are
identified by the words "expects", "anticipates", "believes", "intends",
"estimates" and similar expressions.

     The forward-looking statements in this proxy statement/prospectus and in
the documents incorporated by reference into this document are subject to
various risks and uncertainties, most of which are difficult to predict and
generally beyond the control of Deutsche Telekom, VoiceStream and Powertel.
Accordingly, actual results of Deutsche Telekom following the Deutsche
Telekom/VoiceStream and Deutsche Telekom/Powertel mergers or of VoiceStream
following the VoiceStream/Powertel merger may differ materially from those
expressed in, or implied by, the forward-looking statements. The risks and
uncertainties to which forward-looking statements are subject include:

     - those we discuss above under "Risk Factors Relating to the Deutsche
       Telekom/VoiceStream Merger and the Deutsche Telekom/Powertel Merger" and
       "Risk Factors Relating to the VoiceStream/Powertel Merger;"

     - those we discuss or identify in our public filings with the SEC;

     - risks and uncertainties with respect to our expectations regarding the
       benefits anticipated from the Deutsche Telekom/VoiceStream merger, the
       Deutsche Telekom/Powertel merger and the VoiceStream/Powertel merger;

     - for the mergers involving Deutsche Telekom, effects of foreign exchange
       rate fluctuations;

     - level of demand for telecommunications services, including with regard to
       wireless telecommunications services, access lines, traffic and new
       higher value products;

     - competitive forces, including pricing pressures, technological
       developments, alternative routing developments and our ability to gain
       market share in new markets, including, among others, the United States
       in respect of Deutsche Telekom, and our ability to retain market share in
       existing markets in the face of competition from existing and new market
       entrants;

     - for the mergers involving Deutsche Telekom, effects of Deutsche Telekom's

                        THE VOICESTREAM SPECIAL MEETING

GENERAL

     The special meeting of stockholders of VoiceStream will be held on
__________, 2000, at 8:00 a.m., Pacific time, at ____________. At the
VoiceStream special meeting, VoiceStream stockholders will consider and vote
upon proposals to approve and adopt:

     - the Agreement and Plan of Merger, dated as of July 23, 2000, as amended
       and restated on September 28, 2000, among Deutsche Telekom AG,
       VoiceStream Wireless Corporation and a Delaware corporation formed by
       Deutsche Telekom, pursuant to which that corporation will be merged into
       VoiceStream, and VoiceStream will become a wholly-owned subsidiary of
       Deutsche Telekom.

     - the Agreement and Plan of Reorganization, dated as of August 26, 2000, as
       amended and restated on September 28, 2000, among VoiceStream Wireless
       Corporation, Powertel, Inc. and a wholly-owned subsidiary of VoiceStream,
       pursuant to which that subsidiary will be merged into Powertel, and
       Powertel will become a wholly-owned subsidiary of VoiceStream. The merger
       between VoiceStream and Powertel can occur only if the merger agreement
       between VoiceStream and Deutsche Telekom is terminated.

     If the Deutsche Telekom/VoiceStream merger is completed, VoiceStream will
become a wholly-owned subsidiary of Deutsche Telekom and the
VoiceStream/Powertel merger agreement will automatically terminate. If, however,
the Deutsche Telekom/VoiceStream merger agreement is terminated, the
VoiceStream/Powertel merger may still be completed. Therefore, it is necessary
for VoiceStream stockholders to vote on both the Deutsche Telekom/VoiceStream
merger and the VoiceStream/Powertel merger, even though it is not possible for
both mergers to be completed. We have attached copies of the Deutsche
Telekom/VoiceStream and VoiceStream/Powertel merger agreements to this document
as Annexes A and C, respectively.

RECORD DATE; QUORUM

     Only holders of VoiceStream common shares and VoiceStream voting preferred
shares are entitled to vote on the mergers at the VoiceStream special meeting.
The VoiceStream board of directors has fixed the close of business on
__________, 2000 as the record date for the determination of the stockholders
entitled to notice of, and to vote at, the VoiceStream special meeting. At the
record date, there were outstanding ____________ VoiceStream common shares held
by approximately ____________ VoiceStream stockholders of record, and 3,906,250
VoiceStream voting preferred shares outstanding, all of which are held by
Deutsche Telekom.

     The holders of a majority of the votes entitled to be cast in respect of
VoiceStream common shares and VoiceStream voting preferred shares outstanding at
the record date, represented in person or by proxy, will constitute a quorum for
purposes of the VoiceStream special meeting. A quorum is necessary to hold the
VoiceStream special meeting. Any VoiceStream common shares held in treasury by
VoiceStream or by any of its subsidiaries will not be counted for purposes of a
quorum. Brokers and nominees are allowed to vote on the approval of either the
Deutsche Telekom/VoiceStream merger or the VoiceStream/Powertel merger on behalf
of VoiceStream stockholders only if they receive instructions from such
stockholder on how to vote, and VoiceStream shares that are not voted because
brokers did not receive instructions are referred to as "broker non-votes."
Abstentions and broker non-votes represented at the special meeting count as
present for establishing a quorum. Once a VoiceStream share is represented at
the VoiceStream special meeting, it will be counted for the purpose of
determining a quorum at the VoiceStream special meeting and any adjournment of
the VoiceStream special meeting unless the holder is present solely to object to
the VoiceStream special meeting. However, if a new record date is set for the
adjourned VoiceStream special meeting, then a new quorum will have to be
established.

REQUIRED VOTE

     The completion of the Deutsche Telekom/VoiceStream merger requires the
approval of the Deutsche Telekom/VoiceStream merger agreement by the affirmative
vote of the holders of a majority of the voting power of the outstanding
VoiceStream common shares and VoiceStream voting preferred shares, voting
together as a single class. The completion of the VoiceStream/Powertel merger
requires the approval of the VoiceStream/Powertel merger agreement by a majority
of the votes cast at the VoiceStream special meeting by holders of VoiceStream
common shares and VoiceStream preferred shares, voting together as a single
class. Each VoiceStream common share and VoiceStream voting preferred share
outstanding as of the close of business on the record date, __________, 2000,
entitles the holder to one vote with respect to each merger to be voted upon at
the VoiceStream special meeting. Because the vote to approve the Deutsche
Telekom/VoiceStream merger is based on the number of VoiceStream shares
outstanding and entitled to vote rather than on the number of votes cast,
failure to vote your VoiceStream shares is effectively a vote against approval
of the Deutsche Telekom/VoiceStream merger. Similarly, abstentions and broker
non-votes represented at the VoiceStream special meeting will have the same
effect as votes against approval of the Deutsche Telekom/VoiceStream merger.

     You may vote your VoiceStream shares in any of three ways:

     (1) by completing and returning the accompanying proxy card;

     (2) through the Internet or by telephone, as outlined on the accompanying
         proxy card; or

     (3) by appearing and voting in person at the VoiceStream special meeting.

     At the record date, directors and executive officers of VoiceStream and
their associates and affiliates owned approximately ____% of the outstanding
VoiceStream common shares.

AGREEMENTS TO VOTE IN FAVOR OF THE MERGERS

     In connection with the Deutsche Telekom/VoiceStream merger, VoiceStream
stockholders who, in the aggregate, had sufficient voting power as of the
VoiceStream record date to approve the Deutsche Telekom/VoiceStream merger
entered into separate stockholder agreements with Deutsche Telekom whereby each
of the stockholders has agreed to vote its VoiceStream common shares in favor of
the Deutsche Telekom/VoiceStream merger. See "Summary of the Deutsche
Telekom/VoiceStream Transaction Documents -- Deutsche Telekom's Agreements with
Stockholders of VoiceStream." In addition, the VoiceStream voting preferred
shares held by Deutsche Telekom entitle Deutsche Telekom to cast approximately
____% of the votes, and Deutsche Telekom intends to vote these shares in favor
of the Deutsche Telekom/VoiceStream merger. As a result, VoiceStream stockholder
approval of the Deutsche Telekom/VoiceStream merger is assured.

     In connection with the VoiceStream/Powertel merger, VoiceStream
stockholders who, in the aggregate, had sufficient voting power as of the
VoiceStream record date to approve the VoiceStream/ Powertel merger entered into
stockholder agreements with Powertel whereby each of the stockholders has agreed
to vote its VoiceStream common shares in favor of the VoiceStream/Powertel
merger. See "Summary of Deutsche Telekom/Powertel and VoiceStream/Powertel
Transaction Documents -- Powertel's Agreements with Stockholders of
VoiceStream." As a result, VoiceStream stockholder approval of the
VoiceStream/Powertel merger is assured.

VOTING AND REVOCATION OF PROXIES

     If you vote your VoiceStream common shares or voting preferred shares by
signing a proxy, your shares will be voted at the VoiceStream special meeting as
you indicate on your proxy card. If no instructions are indicated on your signed
proxy card, your VoiceStream common shares or voting preferred shares will be
voted "FOR" the approval of both the Deutsche Telekom/VoiceStream merger and the
VoiceStream/Powertel merger. If you vote your VoiceStream common shares or
voting preferred shares through the Internet or by telephone, your shares will
be voted at the VoiceStream special meeting as instructed.
                                       48
<PAGE>   67

     You may revoke or change your proxy at any time before the proxy is voted
at the VoiceStream special meeting. A proxy may be revoked prior to the vote at
the VoiceStream special meeting in any of the following ways:

     (1) by submitting a written revocation to the Secretary of VoiceStream
         Wireless Corporation at 3650 131st Avenue SE, Bellevue, Washington
         98006;

     (2) by submitting a new proxy dated after the date of the proxy that is
         being revoked; or

     (3) by voting in person at the VoiceStream special meeting.

     However, simply attending the VoiceStream special meeting will not revoke a
proxy. If you do not hold your VoiceStream common shares in your own name, you
may revoke or change a previously given proxy by following the instructions
provided by the bank, broker or other party that is the registered owner of the
shares.

     The VoiceStream board of directors is not aware of any other business to be
brought before the VoiceStream special meeting. If, however, other matters are
properly brought before the VoiceStream special meeting or any adjournment of
the VoiceStream special meeting, the persons appointed as proxies will have
discretionary authority to vote the shares represented by duly executed proxies
in accordance with their discretion and judgment.

     DO NOT INCLUDE VOICESTREAM SHARE CERTIFICATES WHEN RETURNING THE ENCLOSED
PROXY CARD.

     At least 45 days before the expected closing of the Deutsche
Telekom/VoiceStream merger, we will mail to you a form with instructions for
making your election of the consideration you prefer to receive in the Deutsche
Telekom/VoiceStream merger and indicating whether you prefer to receive Deutsche
Telekom ADSs or Deutsche Telekom ordinary shares and a letter of transmittal for
surrendering your VoiceStream share certificates. To make an election, you will
need to complete the form as instructed and send your VoiceStream share
certificates with a completed letter of transmittal so that the escrow agent
receives them no later than the election deadline, which is the fifth business
day before the completion of the Deutsche Telekom/VoiceStream merger. If you
fail to make a valid election before the election deadline, including failing to
send in your VoiceStream share certificates, you will receive the mixed
consideration per VoiceStream common share of 3.2 Deutsche Telekom shares and
$30 in cash, subject to proration and adjustment, and after we complete the
Deutsche Telekom/VoiceStream merger, we will send you instructions explaining
how to exchange your VoiceStream common share certificates for depositary
receipts representing Deutsche Telekom ADSs and cash, (or, if you elect, cash
and certificates for Deutsche Telekom ordinary shares). We will make a public
announcement of the election deadline at least five business days before that
deadline.

SOLICITATION OF PROXIES

     VoiceStream is soliciting, and will bear the cost of soliciting, proxies to
vote on the mergers at the VoiceStream special meeting. Deutsche Telekom,
VoiceStream and Powertel will share equally the amount of the expenses incurred
in connection with the cost of printing and distributing this proxy
statement/prospectus. Deutsche Telekom and VoiceStream will share equally the
amount of the SEC filing fees incurred in connection with registering the
Deutsche Telekom ADSs and Deutsche Telekom ordinary shares issuable upon
completion of the Deutsche Telekom/VoiceStream merger. VoiceStream and Powertel
will share equally the amount of the SEC filing fees incurred in connection with
registering VoiceStream common shares issuable upon completion of the

will make arrangements with brokerage houses and other custodians, nominees and
fiduciaries to send the proxy materials to beneficial owners, and VoiceStream
will reimburse those brokerage houses and custodians for their reasonable
expenses in doing so. ____________ has been retained by VoiceStream to assist in

                          THE POWERTEL SPECIAL MEETING

GENERAL

     The special meeting of stockholders of Powertel will be held on __________,
2000, at 11:00 a.m., Eastern time, at The Cotton Duck, 6101 20th Avenue, Valley,
Alabama 36854. At the Powertel special meeting, the Powertel stockholders will
consider and vote upon proposals to approve and adopt:

     - the Agreement and Plan of Merger dated as of August 26, 2000, as amended
       and restated on September 28, 2000, among Deutsche Telekom, Powertel and
       a Delaware corporation formed by Deutsche Telekom, pursuant to which that
       corporation will be merged into Powertel, and Powertel will become a
       wholly-owned subsidiary of Deutsche Telekom; and

     - the Agreement and Plan of Reorganization dated as of August 26, 2000, as
       amended and restated on September 28, 2000, among VoiceStream, Powertel
       and a wholly-owned subsidiary of VoiceStream, pursuant to which that
       subsidiary will be merged into Powertel, and Powertel will become a
       wholly-owned subsidiary of VoiceStream.

     The Deutsche Telekom/Powertel merger and the VoiceStream/Powertel merger
are mutually exclusive. If the Deutsche Telekom/VoiceStream merger is completed,
then the VoiceStream/Powertel merger agreement will automatically terminate, and
Powertel will merge with a Delaware corporation formed by Deutsche Telekom upon
the terms set forth in the Deutsche Telekom/Powertel merger agreement. If,
however, the Deutsche Telekom/VoiceStream merger agreement is terminated, the
Deutsche Telekom/Powertel merger agreement will also terminate. In that case,
Powertel is expected to merge with the wholly-owned subsidiary of VoiceStream
upon the terms set forth in the VoiceStream/ Powertel merger agreement.
Therefore, it is necessary for Powertel stockholders to vote on both the
Deutsche Telekom/Powertel merger and the VoiceStream/Powertel merger, even
though it is not possible for both mergers to be completed. We have attached
copies of the Deutsche Telekom/Powertel merger agreement and the
VoiceStream/Powertel merger agreement to this proxy statement/prospectus as
Annex B and Annex C, respectively.

RECORD DATE; QUORUM

     Holders of Powertel common shares and preferred shares are entitled to vote
on the Deutsche Telekom/Powertel merger and the VoiceStream/Powertel merger at
the Powertel special meeting. The Powertel board of directors has fixed the
close of business on __________, 2000 as the record date for the determination
of the stockholders entitled to notice of, and to vote at, the Powertel special
meeting. At the record date there were outstanding:

     - ____________Powertel common shares held by approximately ____________
       Powertel stockholders of record;

     - 100,000 Series A preferred shares, all of which are owned by Sonera
       Corporation;

     - 100,000 Series B preferred shares, all of which are owned by SCANA
       Communications Holdings, Inc.;

     - 50,000 Series D preferred shares, all of which are owned by SCANA
       Communications Holdings, Inc.;

     - 50,000 Series E preferred shares, all of which are owned by SCANA
       Communications Holdings, Inc.; and

     - 50,000 Series F preferred shares, all of which are owned by ITC Wireless,
       Inc.

     The holders of shares representing a majority of the votes entitled to be
cast with respect to the proposals at the record date, represented in person or
by proxy, will constitute a quorum for purposes of the Powertel special meeting.
A quorum is necessary to hold the Powertel special meeting. Any Powertel common
shares held in treasury by Powertel or by any of its subsidiaries will not be
counted for purposes

                                       50
<PAGE>   69

of a quorum. Brokers and nominees are allowed to vote on the approval of either
the Deutsche Telekom/ Powertel merger or the VoiceStream/Powertel merger on
behalf of Powertel stockholders only if they receive instructions from such
stockholders on how to vote, and Powertel shares that are not voted because
brokers did not receive instructions are referred to as "broker non-votes."
Abstentions and broker non-votes represented at the special meeting count as
present for establishing a quorum. Once a Powertel share is represented at the
Powertel special meeting, it will be counted for the purpose of determining a
quorum at the Powertel special meeting and any adjournment of the Powertel
special meeting, unless the holder is present solely to object to the Powertel
special meeting. However, if a new record date is set for the adjourned Powertel
special meeting, then a new quorum will have to be established.

REQUIRED VOTE

     The completion of each of the Deutsche Telekom/Powertel merger and the
VoiceStream/Powertel merger requires the approval of the relevant merger
agreement by the affirmative vote of the holders of (A) a majority of the voting
power of the outstanding Powertel common shares and Powertel Series A preferred
shares, voting together as a single class, with the Series A preferred shares
voting on an as-converted-to-common shares basis, and (B) two-thirds of each of
the Series A preferred shares, Series B preferred shares, Series D preferred
shares, Series E preferred shares and Series F preferred shares, each voting as
a separate class. Each Powertel common share outstanding as of the close of
business on __________, 2000 entitles the holder to one vote at the Powertel
special meeting. Each Powertel Series A preferred share outstanding as of the
close of business on __________, 2000 entitles the holder to 46.26774 votes at
the Powertel special meeting when voting together with the common shares on an
as-converted-to-common shares basis. Each Powertel preferred share is entitled
to one vote when voting as a separate class. Because the vote is based on the
number of Powertel shares outstanding rather than on the number of votes cast,
failure to vote your shares is effectively a vote against the mergers. In
addition, abstentions and broker non-votes will have the same effect as votes
against approval of the mergers.

     You may vote your shares in any of three ways:

     (1) by completing and returning the accompanying proxy card;

     (2) through the Internet or by telephone, as outlined on the accompanying
         proxy card; or

     (3) by appearing and voting in person at the Powertel special meeting.

     At the Powertel record date, directors and executive officers of Powertel
and their respective affiliates held approximately ____% of all the outstanding
Powertel common shares. All of the outstanding Powertel preferred shares were
held by the stockholders in the amounts set forth under "-- Record Date; Quorum"
above.

AGREEMENTS TO VOTE IN FAVOR OF THE DEUTSCHE TELEKOM/POWERTEL MERGER

     In connection with the execution of the Deutsche Telekom/Powertel merger
agreement, Powertel stockholders who, in the aggregate, had sufficient voting
power as of the Powertel record date to approve the Deutsche Telekom/Powertel

VOTING AND REVOCATION OF PROXIES

     If you vote your Powertel common shares or Powertel preferred shares by
signing a proxy, your shares will be voted at the Powertel special meeting as
you indicate on your proxy card. If no instructions are indicated on your signed
proxy card, your Powertel common shares or Powertel preferred shares will be
voted "FOR" the adoption of the Deutsche Telekom/Powertel merger agreement and
the VoiceStream/ Powertel merger agreement. If you vote your Powertel common
shares or Powertel preferred shares through the Internet or by telephone, your

         at 1239 O.G. Skinner Drive, West Point, Georgia 31833;

     (2) by submitting a new proxy dated after the date of the proxy that is
         being revoked; or

     (3) by voting in person at the Powertel special meeting.

     However, simply attending the Powertel special meeting will not revoke a
proxy. If you do not hold your Powertel common shares or Powertel preferred
shares in your own name, you may revoke a previously given proxy by following
the revocation instructions provided by the bank, broker or other party that is
the registered owner of the shares.

     The Powertel board of directors is not aware of any other business to be
brought before the Powertel special meeting. If, however, other matters are
properly brought before the Powertel special meeting or any adjournment or
postponement of the Powertel special meeting, the persons appointed as proxies
will have discretionary authority to vote the Powertel shares represented by
duly executed proxies in accordance with their discretion and judgment.

                    THE DEUTSCHE TELEKOM/VOICESTREAM MERGER

BACKGROUND OF THE DEUTSCHE TELEKOM/VOICESTREAM MERGER

     Deutsche Telekom -- General Background

     Deutsche Telekom has been seeking to expand internationally through
acquisitions, investments and joint undertakings in the areas that are the four
pillars of its growth strategy: mobile telecommunications, data/IP/systems,
consumer Internet services and access services. Deutsche Telekom considers
expansion of its international business to be an essential component of its
overall business strategy. In particular, Deutsche Telekom has aimed to build on
its strength in Europe and to expand its reach in the United States. From time
to time, Deutsche Telekom has engaged and may continue to engage in discussions
with other parties that may lead to one or more substantial cross-border
acquisitions or business combinations. In that connection, Deutsche Telekom
retained Donaldson, Lufkin & Jenrette and Dresdner Kleinwort Benson in November
1999 as financial advisors to advise it on acquisition alternatives in the U.S.
wireless telecommunications industry. Over the next several months, Deutsche
Telekom, with the aid of Donaldson Lufkin & Jenrette and Dresdner Kleinwort
Benson, explored several wireless opportunities in the United States, including
an acquisition of VoiceStream. Among other things, Deutsche Telekom and its
financial advisors analyzed the U.S. wireless market, possible valuations of
VoiceStream and alternative transaction structures and considerations.

     VoiceStream -- General Background

     Following the spin-off of VoiceStream from Western Wireless in May 1999,
the VoiceStream board of directors has sought to expand the geographical scope
of, and enhance the services provided by, its wireless business operations to
enable VoiceStream to become a nationwide service provider and to compete
effectively against larger wireless carriers. In late 1999 and the first half of
2000, VoiceStream acquired wireless carriers Omnipoint Corporation and Aerial
Communications, Inc., received a $957 million investment from Hutchison Whampoa
Ltd., a $500 million investment from Sonera Corporation, entered into a new
$3.25 billion credit agreement and raised $1.46 billion in a high-yield debt
offering.

     As a result of these acquisitions and financing activities, by the end of
the first half of 2000, VoiceStream had become a national competitor in the U.S.
wireless telecommunications industry. VoiceStream's board of directors and
management believed that VoiceStream's size and financial resources relative to
other national competitors, and the conditions and trends in the
telecommunications industry, including the on-going consolidation of
telecommunications companies both in the United States and globally, would
require VoiceStream to continue to expand if VoiceStream were to remain a strong
competitor in the wireless telecommunications industry, and VoiceStream's board
of directors and management understood that this expansion strategy would
require VoiceStream to raise and spend billions of dollars in the future.

     On a number of occasions during the year 2000, VoiceStream received
inquiries from U.S. and international communications companies expressing
interest in an acquisition of all of VoiceStream or a significant minority
investment in VoiceStream. In response to these inquiries and contacts,
VoiceStream's management, together with Goldman, Sachs & Co., VoiceStream's
financial advisor, held preliminary discussions with 10 parties who expressed
interest in such possible transactions with VoiceStream. Of these parties, three
communications companies expressed interest in acquiring all of VoiceStream,
including Deutsche Telekom and another party which submitted a preliminary
acquisition proposal in July. In addition, VoiceStream also received written
proposals from two international communications companies in addition to
Deutsche Telekom that expressed an interest in acquiring a significant minority
stake in VoiceStream. One of these parties, in addition to Deutsche Telekom,
conducted due diligence with VoiceStream's management, and VoiceStream delivered
to such party drafts of agreements under which such investment would be made.

     As discussed below under "-- Recommendation and Considerations of the
VoiceStream Board of Directors," the VoiceStream board determined that the
Deutsche Telekom/VoiceStream merger, including

                                       54
<PAGE>   73

the $5 billion equity investment by Deutsche Telekom which was agreed to at the
time of signing of the Deutsche Telekom/VoiceStream merger agreement, was the
most desirable strategic alternative for VoiceStream as well as the most
attractive transaction that was available.

     The Deutsche Telekom/VoiceStream Transaction

     On March 7, 2000, a representative of Donaldson Lufkin & Jenrette, one of
Deutsche Telekom's financial advisors, contacted John W. Stanton, chairman and
chief executive officer of VoiceStream, by telephone to inform Mr. Stanton that
Deutsche Telekom was seeking to expand its telecommunications business into the
United States and that Deutsche Telekom had an interest in acquiring VoiceStream
and to arrange a meeting between Mr. Stanton and Dr. Ron Sommer, chairman of
Deutsche Telekom's management board. Mr. Stanton and Dr. Sommer, together with
other representatives of VoiceStream and Deutsche Telekom, met in New York on
March 13. At this meeting, the parties discussed the telecommunications industry
in general, and Deutsche Telekom indicated its interest in acquiring VoiceStream
to expand its wireless telecommunications business into the United States.

     On March 29, 2000, Mr. Stanton and Dr. Sommer, together with other
representatives of VoiceStream and Deutsche Telekom, met again in New York. At
this meeting, Deutsche Telekom indicated that it was considering making a
proposal to acquire VoiceStream in a transaction in which stockholders of
VoiceStream would receive shares of T-Mobile, which is the Deutsche Telekom
subsidiary through which Deutsche Telekom conducts a substantial portion of its
mobile telecommunications businesses. Mr. Stanton said that VoiceStream would
not be willing to consider such a proposal, if made, in light of the absence of
an existing public trading market for the shares of T-Mobile and a number of
other contingencies and uncertainties surrounding T-Mobile.

     On June 1, 2000, in light of press reports concerning a possible minority
investment in VoiceStream by a third party, Donaldson, Lufkin & Jenrette
contacted Goldman Sachs and VoiceStream to determine whether VoiceStream would
consider a proposal by Deutsche Telekom for an acquisition of VoiceStream or an
equity investment in VoiceStream. Goldman Sachs indicated that VoiceStream would
be willing to consider a written proposal from Deutsche Telekom, and requested
that any such proposal be provided no later than early June because of the
presence of other possible bidders. Later that day or the next, Dr. Sommer
telephoned Mr. Stanton and informed him that Deutsche Telekom would like to
continue discussions of a possible acquisition of VoiceStream by Deutsche
Telekom. Mr. Stanton indicated that VoiceStream would be willing to consider a
written proposal from Deutsche Telekom to acquire VoiceStream and requested that
such proposal be provided no later than early June.

     On June 6, 2000, Deutsche Telekom submitted a written, preliminary proposal
to acquire all of VoiceStream. The proposal contemplated the acquisition of
VoiceStream solely for Deutsche Telekom ordinary shares at a fixed exchange
ratio to be negotiated that would imply a price of between $170 and $190 per
VoiceStream share.

     On June 12, 2000, Mr. Stanton sent a written reply to Deutsche Telekom's
proposal which stated that VoiceStream would be willing to consider an
acquisition proposal for VoiceStream of at least $200 per VoiceStream common
share provided that a significant component of the purchase price be paid in
cash and that the proposal contain protection for VoiceStream stockholders if
the price of Deutsche Telekom's shares declined. The reply indicated that
VoiceStream would permit Deutsche Telekom to conduct limited due diligence if
Deutsche Telekom believed it could raise the value of its proposal to at least
$200 per VoiceStream common share.

     On June 15, 2000, Mr. Stanton and Dr. Sommer spoke by telephone and
discussed terms of a potential transaction. Also on June 15, 2000,
representatives of the two companies held a conference call in which the parties
agreed that VoiceStream would provide Deutsche Telekom with preliminary due
diligence information. On June 21, 2000, Deutsche Telekom and VoiceStream
entered into a non-disclosure agreement.

                                       55
<PAGE>   74

     On June 22, 2000, Deutsche Telekom submitted a revised written, preliminary
proposal to acquire VoiceStream, indicating that it would be willing to pay at
least $200 per VoiceStream common share, with 10% of the consideration to be
paid in cash and the balance to be paid in Deutsche Telekom shares. Deutsche
Telekom's proposal stated that the share portion of the consideration would be
subject to a collar that would provide VoiceStream stockholders with some value
protection in the event of a decrease in the price of Deutsche Telekom's shares.
The proposal also indicated that, as part of any definitive agreement with
VoiceStream, Deutsche Telekom would require VoiceStream's principal stockholders
(representing more than 50% of VoiceStream's voting power on a fully-diluted
basis) to agree to support the transaction and to restrict dispositions of the
Deutsche Telekom shares they would receive in the transaction for a period of at
least six months after closing of the transaction.

     On June 22, 2000, Mr. Stanton sent a written reply to Dr. Sommer and Mr.
Jeffrey Hedberg, a member of the Deutsche Telekom management board, raising a
number of business issues with respect to Deutsche Telekom's proposal and
scheduling due diligence meetings in Seattle, Washington commencing June 27. Mr.
Stanton requested that Deutsche Telekom be prepared to make a definitive
proposal by July 5.

     On June 27 through June 29, 2000, Deutsche Telekom and its representatives
met in Seattle, Washington with senior members of VoiceStream's management and
conducted a due diligence review of VoiceStream's business, operations,
properties and finances. The parties discussed the terms of a separate
significant investment by Deutsche Telekom in VoiceStream.

     On July 5, 2000, Deutsche Telekom delivered to VoiceStream a written
acquisition proposal, including a draft merger agreement and draft agreement to
be entered into by VoiceStream's major stockholders. Deutsche Telekom's proposal
was to acquire all of the outstanding shares of VoiceStream for a combination
per VoiceStream common share of $10 in cash and Deutsche Telekom shares having
an anticipated value of $190. The proposal contained a collar designed to
provide that the portion of the consideration payable in Deutsche Telekom shares
would have a value of $190 as long as the trading price of Deutsche Telekom
ordinary shares were in the range of 54 euros to 69 euros. If the trading price
of Deutsche Telekom ordinary shares were below that range, a maximum agreed
fixed exchange ratio would apply and the trading value of the consideration
payable in Deutsche Telekom shares would be less than $190. Conversely, if the
trading price of Deutsche Telekom shares were above the range, a minimum fixed
exchange ratio would apply and the trading value of the Deutsche Telekom shares
would exceed $190. Deutsche Telekom also proposed to invest $5 billion in
VoiceStream on terms that Deutsche Telekom believed to be customary for
strategic investments of this kind, but which VoiceStream believed would have
the effect of significantly limiting VoiceStream's ability to use the funds
unless Deutsche Telekom specifically approved. The form of stockholders
agreement included as part of the proposal would obligate VoiceStream's
principal stockholders to vote for the transaction at the VoiceStream special
meeting and not to transfer any VoiceStream common shares or Deutsche Telekom
shares prior to six months after the closing of the Deutsche Telekom/VoiceStream
merger.

     On July 7, 2000, Mr. Stanton responded to Deutsche Telekom's proposal of
July 5, requesting revisions to various business terms proposed by Deutsche
Telekom and suggesting that negotiations commence the following week among the
principals and their outside financial advisors. The parties agreed to meet in
New York on Monday, July 10 to discuss Deutsche Telekom's acquisition proposal.

     On July 7, 2000, VoiceStream received an indication of interest from a
non-U.S. wireless company to combine with VoiceStream. The indication of
interest said that the third party was prepared to consider offering $160 to
$180 per VoiceStream common share but did not propose a specific transaction
structure and indicated that the timing of any transaction and the form of
consideration could be affected by other strategic transactions involving the
third party. The third party indicated that, as an alternative, it would also
consider making an investment in VoiceStream of between $5 billion and $8
billion as the first stage of a transaction that would result in the acquisition
of all of VoiceStream.

                                       56
<PAGE>   75

     On July 9, 2000, VoiceStream informed the third party that VoiceStream
would be willing to consider an acquisition proposal by such third party only if
its stockholders were to receive consideration of at least $200 per VoiceStream
common share.

     On July 10, 2000, Mr. Stanton and other members of VoiceStream's senior
management and representatives of VoiceStream's financial advisor met with
members of Deutsche Telekom's management and representatives of its financial
advisor in New York to discuss the terms proposed by Deutsche Telekom and
modifications of such terms. At this meeting the parties discussed major terms
of a transaction, including financial terms, structure, tax considerations,
retention of VoiceStream's management and employees after the Deutsche
Telekom/VoiceStream merger and the portion of the purchase price that would be
payable to VoiceStream stockholders in cash. The parties also discussed an
investment by Deutsche Telekom in VoiceStream to be made prior to the closing of
a merger between the parties, the impact of the acquisition of VoiceStream on
Deutsche Telekom's plans for its mobile telecommunications subsidiary, T-Mobile,
and representation of VoiceStream on the supervisory and management boards of
Deutsche Telekom and T-Mobile.

     During the period from July 12 to July 14, 2000, members of VoiceStream's
and Deutsche Telekom's respective managements and their respective financial
advisors met daily at Sun Valley, Idaho and continued to discuss a potential
transaction. On July 14, 2000, Deutsche Telekom and VoiceStream reached
agreement on the Deutsche Telekom/VoiceStream merger consideration per
VoiceStream share by raising the cash portion to $30 and fixing the exchange
ratio at 3.2 Deutsche Telekom shares, implying a value of about $205 per
VoiceStream common share, based on the closing price of Deutsche Telekom ADSs on
July 13, 2000. This agreement was subject to mutually satisfactory negotiation
of the other terms of the Deutsche Telekom/VoiceStream merger agreement, the
agreements to be entered into by VoiceStream's principal stockholders and of a
significant investment by Deutsche Telekom in VoiceStream. In regard to the
investment, Deutsche Telekom and VoiceStream agreed that Deutsche Telekom would
invest $5 billion in a VoiceStream security that would be convertible into
VoiceStream common shares at a conversion price of $160 per VoiceStream common
share and having other terms which were to be negotiated. Deutsche Telekom said
that obtaining agreements from VoiceStream's stockholders representing in the
aggregate more than 50% of the voting power of VoiceStream would be a condition
to Deutsche Telekom's participation in the transaction.

     On July 19, 2000, VoiceStream's representatives were contacted by telephone
by representatives of the financial advisors for the third party which had
submitted the written indication of interest on July 7, 2000. The
representatives indicated by phone that the third party would consider making a
proposal to acquire VoiceStream at a value in the range of $200 per VoiceStream
common share. Such representatives also stated that the third party would
require a period of several weeks to conduct due diligence of VoiceStream and
that the timing of a transaction could be delayed by other strategic
transactions involving the third party.

     During the period between July 14 and July 23, 2000, members of
VoiceStream's and Deutsche Telekom's respective senior management and their
respective legal and financial advisors held continuous meetings in New York to
negotiate the terms and conditions of the Deutsche Telekom/VoiceStream merger
agreement, the $5 billion investment by Deutsche Telekom in VoiceStream and
related agreements between the parties. Representatives of Deutsche Telekom held
discussions with members of senior management of VoiceStream regarding the
retention of senior management and other employees of VoiceStream by Deutsche
Telekom after the completion of the Deutsche Telekom/VoiceStream merger and the
terms of such retention arrangements. Discussions also continued between
VoiceStream and Deutsche Telekom and VoiceStream's major stockholders with
respect to the terms of the proposed stockholders agreements between Deutsche
Telekom and the major stockholders of VoiceStream.

     On July 18, 2000, VoiceStream convened a meeting of its board. At this
meeting, the VoiceStream board received an update from VoiceStream's management
and its financial and legal advisors on the status of the negotiations with
Deutsche Telekom and with the third party that had submitted the proposal on
July 7, 2000. The VoiceStream board also reviewed the history and status of the
various proposals

                                       57
<PAGE>   76

which had been made to VoiceStream for an acquisition or significant minority
investment. Based on concerns about the timing, feasibility, structure and value
which might be realized in a transaction with the third party, and noting the
contingent nature of the third party's preliminary proposal, the VoiceStream
board instructed management to focus its efforts on a transaction with Deutsche
Telekom and to convey its concerns to the third party. The VoiceStream board
meeting was adjourned until July 21, 2000.

     On July 21, 2000, the VoiceStream board continued to review the proposed
Deutsche Telekom/ VoiceStream merger and VoiceStream's other strategic
alternatives. Representatives of VoiceStream's management and VoiceStream's
financial and legal advisors made presentations regarding the various strategic
alternatives available to VoiceStream, including (1) continuing as an
independent entity and entering into strategic financing or business
arrangements with other industry participants or financing sources that would
assist VoiceStream in financing its business strategy, (2) pursuing one or more
significant acquisitions of other wireless telecommunications companies and (3)
entering into a combination with Deutsche Telekom or the third party that had
submitted the preliminary proposal on July 7, 2000, as orally modified by its
financial advisors on July 19, 2000. VoiceStream's management and advisors then
reviewed for the VoiceStream board the status of the negotiations with Deutsche
Telekom and the business and strategic rationale for the proposed Deutsche
Telekom/VoiceStream merger transaction, and VoiceStream's legal counsel
discussed certain legal considerations relating to the proposed transactions.
VoiceStream's management and advisors also reviewed, among other things, the
matters set forth under "Risk Factors Relating to the Deutsche
Telekom/VoiceStream Merger and the Deutsche Telekom/Powertel Merger,"
"-- Deutsche Telekom's Reasons for the Deutsche Telekom/VoiceStream Merger" and
"-- Recommendation and Considerations of the VoiceStream Board of Directors," as
well as the provisions contained in the draft Deutsche Telekom/VoiceStream
merger agreement and the related documents, including the various stockholders
agreements in which VoiceStream stockholders owning in the aggregate more than
50% of the voting power of VoiceStream would agree to vote for the Deutsche
Telekom/VoiceStream merger and not to transfer their shares of VoiceStream or
Deutsche Telekom for certain specified periods. Goldman Sachs made presentations
to the VoiceStream board concerning financial aspects of the proposed Deutsche
Telekom/VoiceStream merger and discussed financial aspects of the various
strategic alternatives available to VoiceStream. The VoiceStream board meeting
was again adjourned until July 23, 2000.

     Deutsche Telekom's management board discussed a potential acquisition
transaction involving VoiceStream and a minority investment in VoiceStream on
various occasions at regularly scheduled meetings during the period from March
through July 2000. On July 23, 2000, Deutsche Telekom's supervisory board met in
Bonn, Germany to consider the proposed transactions. At this meeting, the
supervisory board approved and authorized the execution of the Deutsche
Telekom/VoiceStream merger agreement and the agreements providing for Deutsche
Telekom's $5 billion investment in VoiceStream, subject to finalization by the
parties' management and respective legal advisors.

     Also on July 23, 2000, the VoiceStream board continued to review and
consider the proposed merger with Deutsche Telekom. VoiceStream's management and
financial and legal advisors reviewed the terms of the Deutsche
Telekom/VoiceStream merger agreement and described the resolution of all
significant open issues between VoiceStream and Deutsche Telekom.
Representatives of Goldman Sachs confirmed the financial analyses presented on
July 21 and then delivered Goldman Sachs' oral opinion, later confirmed in
writing, that as of the date of that opinion, the merger consideration in
aggregate to be received by holders of VoiceStream common shares was fair from a
financial point of view to those holders of VoiceStream common shares. Following
further discussion and consideration, the VoiceStream board (with one director
not present) unanimously approved and authorized the execution of the Deutsche
Telekom/VoiceStream merger agreement and the agreements providing for Deutsche
Telekom's $5 billion investment in VoiceStream on the terms discussed at the
VoiceStream board meeting, subject to finalization by the parties' management
and respective legal advisors.

     In the evening of July 23, representatives of Deutsche Telekom's and
VoiceStream's respective management and legal advisors completed the definitive
Deutsche Telekom/VoiceStream merger agreement, stockholder agreements,
investment agreement and related documents, and thereafter the
                                       58
<PAGE>   77

parties executed those documents, and Deutsche Telekom and VoiceStream's
principal stockholders entered into the stockholder agreements.

     On July 24, 2000, Deutsche Telekom and VoiceStream issued a joint press
release announcing the transaction.

DEUTSCHE TELEKOM'S REASONS FOR THE DEUTSCHE TELEKOM/VOICESTREAM MERGER

     Deutsche Telekom believes that the addition of VoiceStream to Deutsche
Telekom's mobile telephony operations will make Deutsche Telekom a more
competitive telecommunications company with greater prospects for growth than
either Deutsche Telekom or VoiceStream would have on its own, and will generate
significant opportunities to deliver greater value to Deutsche Telekom
shareholders (which would include former VoiceStream stockholders after the
Deutsche Telekom/VoiceStream merger). Deutsche Telekom believes that VoiceStream
provides it with a strong entry opportunity into the U.S. wireless
telecommunications market, based on the same GSM technology employed by Deutsche
Telekom, and believes that Deutsche Telekom will provide VoiceStream with the
necessary capital resources, technology expertise and global reach to provide
cost-competitive service and accelerate the introduction of next-generation
voice and data services in the United States.

     High-Growth U.S. Wireless Telecommunications Industry.  Deutsche Telekom's
objective is to become a global player in four major telecommunications
segments: mobile telecommunications, data/IP/systems, consumer Internet services
and network access services. The U.S. telecommunications industry is the world's
largest and its wireless telecommunications sector, which is its most
significant growth area, is one of the most attractive wireless markets
globally. Deutsche Telekom believes that the U.S. wireless telecommunications
sector has significant growth potential and that the combined company will be
well positioned to take advantage of this opportunity.

     VoiceStream is one of the Fastest Growing Wireless Operators in the United
States.  VoiceStream is one of the fastest growing wireless operators in the
United States in terms of subscriber growth rate with the highest annualized
penetration rate. VoiceStream's licenses enable it to operate in 23 of the 25
largest markets in the United States in terms of POPs, with access to 220
million potential customers. VoiceStream's current network coverage enables
access to approximately 100 million potential customers and VoiceStream expects
this figure to increase to 120 million customers during 2001. Access to these
customers is a key factor in exploiting the potential of the wireless
telecommunications business. Deutsche Telekom believes that these capabilities
will enable it to implement its objective of becoming a global player in this
market.

     First Transatlantic Wireless Operator Utilizing the GSM Standard.  Deutsche
Telekom and VoiceStream have compatible network platforms utilizing the GSM
technology, which is the established standard in most countries outside the
United States. VoiceStream is the only U.S. wireless telecommunications provider
with a near-national GSM network. The combination of Deutsche Telekom and
VoiceStream will create the first transatlantic wireless operator utilizing the
GSM standard. Together, Deutsche Telekom and VoiceStream will offer seamless
services over a common technology platform and provide customer-friendly
features, such as global roaming, unified billing and worldwide customer
service. Deutsche Telekom believes that these services, which currently are not
offered in this form by any other U.S. provider, will give the combined company
a competitive edge in the U.S. wireless telecommunications industry. The
combined company will be, after the combination, the number one global GSM
wireless telecommunications operator in terms of POPs with approximately 375
million POPs. When referring to the number of "POPs" of any given company, the
reference is to the number of residents of geographic areas in which that
company owns, either directly or through wholly-owned or majority-owned
subsidiaries, a license to provide mobile telecommunications services. The
combined company also will be, after the combination, the number ____ global GSM
provider in terms of number of subscribers at September 30, 2000 (assuming
completion of the Deutsche Telekom/VoiceStream merger on that date).

                                       59
<PAGE>   78

     VoiceStream's Management.  VoiceStream's senior executive team, which has
substantial experience in the industry, has agreed to fully support the Deutsche
Telekom/VoiceStream merger and the integration with Deutsche Telekom and is
expected to lead Deutsche Telekom's wireless telecommunications activities in
the U.S. market.

     Economies of Scale.   Deutsche Telekom believes that because the companies
use compatible network platforms, there is significant potential for growth that
may be realized relatively quickly and that the companies will be able to avoid
significant costs that they would otherwise have to incur if their networks were
not compatible. Deutsche Telekom also believes that substantial cost savings are
likely to accrue as a result of the Deutsche Telekom/VoiceStream combination.

RECOMMENDATION AND CONSIDERATIONS OF THE VOICESTREAM BOARD OF DIRECTORS

     On July 23, 2000, the board of directors of VoiceStream, by unanimous vote
of all of the directors present (with one director absent), determined the
Deutsche Telekom/VoiceStream merger and the other transactions contemplated by
the Deutsche Telekom/VoiceStream merger agreement to be advisable, fair to and
in the best interests of VoiceStream and its stockholders, and approved and
adopted the Deutsche Telekom/VoiceStream merger agreement. ACCORDINGLY, THE
VOICESTREAM BOARD RECOMMENDS THAT THE STOCKHOLDERS OF VOICESTREAM VOTE "FOR"
APPROVAL AND ADOPTION OF THE DEUTSCHE TELEKOM/VOICESTREAM MERGER AGREEMENT AT
THE VOICESTREAM SPECIAL MEETING.

     In the course of reaching its decision to adopt the Deutsche
Telekom/VoiceStream merger agreement, the VoiceStream board consulted with
management, as well as with its outside legal counsel and financial advisors,
and considered the following material factors:

     - Financial Terms -- Premium Valuation.  The VoiceStream board noted that:

          -- The per share value of the Deutsche Telekom/VoiceStream merger
             consideration on the day the Deutsche Telekom/VoiceStream merger
             agreement was signed (based on the closing market price of Deutsche
             Telekom ordinary shares on July 21, 2000, the last trading day
             prior to the signing) represented a premium of approximately 31%
             over the closing price of VoiceStream common shares on the last
             trading day prior to the VoiceStream board's approval, 57% over the
             closing price of VoiceStream common shares on July 10, 2000, the
             last date prior to public reports of merger discussions between
             Deutsche Telekom and VoiceStream, and approximately 58% and 96%
             over the average closing prices of VoiceStream common shares for
             the three and six month periods leading up to the announcement of
             the Deutsche Telekom/VoiceStream merger agreement, respectively;
             and

          -- The merger consideration also reflected very significant premia in
             comparison to historical ratios of the relative trading prices of
             Deutsche Telekom ordinary shares and VoiceStream common shares.

     - Alternatives to the Merger.  VoiceStream had considered a number of
       strategic alternatives and concluded that the Deutsche
       Telekom/VoiceStream merger represented the most desirable strategic
       alternative for VoiceStream, as well as the most attractive opportunity
       that was available to VoiceStream and its stockholders. Specifically:

          -- The VoiceStream board believed that in order to compete effectively
             in the wireless telecommunications industry, VoiceStream would need
             to continue its strategy of expanding its geographic coverage
             (including by acquiring spectrum licenses), building out its
             network in areas where it held licenses and growing its subscriber
             base. The VoiceStream board considered that this strategy entails
             considerable risk and would require VoiceStream to raise
             significant amounts of new debt and equity capital;

          -- The VoiceStream board considered various strategic alternatives
             available to VoiceStream, including (1) continuing as an
             independent entity and entering into strategic financing or
             business arrangements with other industry participants or financing
             sources that would assist

                                       60
<PAGE>   79

          VoiceStream in financing its business strategy, (2) pursuing one or
          more significant acquisitions of other wireless communications
          companies and (3) entering into a combination with or being acquired
          by a major telecommunications company of national or global scale, or
          a company in another industry;

          -- VoiceStream's directors and management investigated and discussed
             these strategic alternatives over a period of months, and, during
             this period, were in contact with and/or engaged in discussions
             with numerous other parties interested in acquiring, being acquired
             by, or engaging in a strategic or financial alliance with
             VoiceStream, as discussed above under "-- Background of the
             Deutsche Telekom/VoiceStream Merger;" and

          -- The possibility of a combination between Deutsche Telekom and
             VoiceStream received substantial publicity commencing at least two
             weeks before Deutsche Telekom and VoiceStream announced the
             Deutsche Telekom/VoiceStream merger, and earlier a possible
             strategic investment in VoiceStream was the subject of considerable
             publicity. Notwithstanding the investigations and discussions
             described above, and despite the publicity, no party other than the
             third party referred to above indicated an interest in engaging in
             a business combination transaction at a value to VoiceStream
             stockholders comparable to that offered by Deutsche Telekom. The
             preliminary proposal from the third party was not a firm proposal,
             did not offer the assurances of value or completion offered by
             Deutsche Telekom, and was subject to a due diligence contingency.

     - Opinion of Financial Advisor.  Goldman Sachs, VoiceStream's financial
       advisor, made presentations to the VoiceStream board concerning financial
       aspects of the proposed Deutsche Telekom/VoiceStream merger and of the
       various strategic alternatives available to VoiceStream, and delivered
       its oral opinion, later confirmed in writing, that as of the date of that
       opinion, the merger consideration in aggregate to be received by holders
       of VoiceStream common shares was fair from a financial point of view to
       those holders of VoiceStream common shares.

     - $5 billion Investment by Deutsche Telekom.  The VoiceStream board viewed
       favorably Deutsche Telekom's willingness to invest $5 billion in
       VoiceStream convertible preferred shares at an effective price of $160
       per VoiceStream common share irrespective of whether the Deutsche
       Telekom/VoiceStream merger were completed. This investment (which was
       completed on September 6, 2000) will help VoiceStream to finance its
       existing business strategy in the near term, including the potential
       acquisition of spectrum licenses.

     - Complementary Strategies and Technologies.  The VoiceStream board
       believed that there is a strong strategic and technology fit between
       Deutsche Telekom's and VoiceStream's mobile communications businesses and
       operations. In particular, the VoiceStream board noted that:

          -- VoiceStream's and Deutsche Telekom's mobile communications services
             are based on compatible network platforms utilizing GSM technology,
             which is the established standard in most countries outside the
             United States; and

          -- VoiceStream is the only U.S. wireless communications provider with
             a nationwide GSM network.

     - New Opportunities for Growth.  The VoiceStream board believed that
       combining VoiceStream's and Deutsche Telekom's mobile communications
       businesses will create growth opportunities not available to either
       company without the Deutsche Telekom/VoiceStream merger. These include
       the opportunities:

          -- to offer seamless services on a global basis over a common
             technology platform and to provide services such as global roaming,
             unified billing and worldwide customer service;

          -- accelerate the introduction by VoiceStream of next-generation
             wireless voice and data services, such as mobile Internet and
             multimedia applications; and

                                       61
<PAGE>   80

          -- to use Deutsche Telekom's greater financial resources to finance
             VoiceStream's growth-focused business strategy (which is expected
             to require significant capital commitments in the near term).

     The VoiceStream board observed that these opportunities could enable the
     combined company to grow more quickly and beyond the levels VoiceStream
     could be expected to achieve without the Deutsche Telekom/VoiceStream
     merger.

     - Likelihood of Completion.  The VoiceStream board believed that the nature
       and relatively limited number of conditions to the completion of the
       Deutsche Telekom/VoiceStream merger, and the strength of Deutsche
       Telekom's obligations to fulfill those conditions, increase the
       likelihood that the Deutsche Telekom/VoiceStream merger will be
       completed.

     - Tax-Free Treatment.  It is expected that the portion of the merger
       consideration to be received by VoiceStream stockholders in the form of
       Deutsche Telekom ADSs or Deutsche Telekom ordinary shares will be
       tax-free to those stockholders for U.S. federal income tax purposes,
       although the VoiceStream board also considered that the cash portion of
       the Deutsche Telekom/VoiceStream merger consideration would be taxable
       for U.S. federal income tax purposes. See "U.S. Federal and German Tax
       Consequences."

     The VoiceStream board also considered the following potentially negative
factors associated with the Deutsche Telekom merger:

     - the risks described under "Risk Factors Relating to the Deutsche
       Telekom/VoiceStream Merger and the Deutsche Telekom/Powertel Merger;"

     - that legislation had been proposed in the U.S. Congress which, if
       enacted, would have the effect of preventing the U.S. regulatory
       approvals necessary for the Deutsche Telekom/VoiceStream merger, and the
       risk that there may be other legislation or other political or regulatory
       opposition to the Deutsche Telekom/VoiceStream merger that could delay,
       impede or prohibit the Deutsche Telekom/VoiceStream merger;

     - that (1) the Deutsche Telekom/VoiceStream merger agreement is required to
       be submitted to the stockholders even if the VoiceStream board withdraws
       or changes its recommendation that VoiceStream stockholders vote in favor
       of the merger and (2) because VoiceStream stockholders representing in
       excess of 50% of the outstanding voting power have entered into
       stockholder agreements with Deutsche Telekom and have agreed to vote
       their shares in favor of the merger agreement, stockholder approval of
       the merger is assured even if the VoiceStream board were to withdraw or
       change its recommendation. These facts would likely discourage other
       potentially interested third parties from proposing an alternative or
       superior transaction to VoiceStream and would prevent VoiceStream from
       engaging in any such transaction if proposed;

     - that Deutsche Telekom ordinary shares and Deutsche Telekom ADSs have
       experienced substantial price volatility in the past year;

     - the risk that because the exchange ratios for the all-stock election and
       the stock portion of the mixed election are fixed, the value of the
       merger consideration to VoiceStream stockholders receiving Deutsche
       Telekom shares or Deutsche Telekom ADSs in the Deutsche Telekom/
       VoiceStream merger could decrease prior to the completion of the merger,
       and the merger agreement does not contain a "collar" or other mechanism
       that could mitigate the effect of a decrease in the trading price of
       Deutsche Telekom shares (except that the VoiceStream board has the right
       to terminate the Deutsche Telekom/VoiceStream merger if the trading price
       of Deutsche Telekom ordinary shares falls below 33 euros as calculated in
       accordance with the Deutsche Telekom/VoiceStream merger agreement during
       a 15 day measurement period shortly prior to completion of the merger);

     - that Deutsche Telekom is organized under German law and that the Federal
       Republic of Germany and Kreditanstalt fur Wiederaufbau (KfW), which is a
       development bank that is 80 percent owned
                                       62
<PAGE>   81

       by the Federal Republic and 20 percent owned by the German Federal
       States, currently own in the aggregate approximately 58.2% of Deutsche
       Telekom's shares, and after the completion of the Deutsche
       Telekom/VoiceStream merger the aggregate ownership of Deutsche Telekom by
       the Federal Republic of Germany and KfW is expected to be diluted to
       approximately 46% of Deutsche Telekom's shares;

     - that the market price for Deutsche Telekom shares to be received by
       VoiceStream stockholders in the Deutsche Telekom/VoiceStream merger may
       be adversely affected by the prospect of future sales of Deutsche Telekom
       shares by the Federal Republic of Germany and KfW, Deutsche Telekom's two
       largest shareholders, or by current VoiceStream stockholders who are not
       permitted to hold equity securities of non-U.S. companies or who
       otherwise elect not to hold Deutsche Telekom shares in their portfolios;
       and

     - the risk that, because of potential proration or adjustment, VoiceStream
       stockholders may receive a form of consideration in the Deutsche
       Telekom/VoiceStream merger different from that which they elected to
       receive, and the potential tax consequences to VoiceStream stockholders
       who receive more cash than they elected to receive.

     The VoiceStream board believed and continues to believe that these
potential risks are greatly outweighed by the potential benefits anticipated to
result from the Deutsche Telekom/VoiceStream merger.

     In considering the proposed Deutsche Telekom/VoiceStream merger, the
directors of VoiceStream were aware of the interests of certain officers and
directors in the Deutsche Telekom/VoiceStream merger described below under
"-- Interests of Directors and Officers of VoiceStream in the Deutsche Telekom/
VoiceStream Merger."

     The foregoing discussion addresses the material information and factors
considered by the VoiceStream board in its consideration of the Deutsche
Telekom/VoiceStream merger, including factors that support the Deutsche
Telekom/VoiceStream merger as well as those that may weigh against it. The
VoiceStream board conducted numerous discussions of the factors described above,
including asking questions of VoiceStream's management and legal and financial
advisors. In view of the variety of factors and the amount of information
considered, the VoiceStream board did not find it practical to, and did not,
make specific assessments of, quantify or otherwise assign relative weights to
the specific factors considered in reaching its determination. In addition, the
VoiceStream board did not undertake to make any specific determination as to
whether any particular factor, or any aspect of any particular factor, was
favorable or unfavorable to its ultimate determination. The determination to
approve the Deutsche Telekom/ VoiceStream merger was made after consideration of
all of the factors as a whole. In addition, individual members of the
VoiceStream board may have given different weights to different factors.

OPINION OF VOICESTREAM'S FINANCIAL ADVISOR

  VoiceStream Fairness Opinion

     Goldman Sachs has acted as financial advisor to VoiceStream in connection
with the Deutsche Telekom/VoiceStream merger. On July 23, 2000, Goldman Sachs
delivered its oral opinion to the VoiceStream board, subsequently confirmed in
writing, that, as of July 23, 2000, the Deutsche Telekom/ VoiceStream merger
consideration in aggregate to be received by holders of VoiceStream common
shares was fair from a financial point of view to those holders of VoiceStream
common shares.

     For purposes of the opinion and this description of the opinion, merger
consideration means the right to receive, with respect to each VoiceStream
common share, at the election of the holder of that share, (1) 3.7647 Deutsche
Telekom ordinary shares as more fully set forth in the Deutsche Telekom/
VoiceStream merger agreement, (2) $200 in cash, or (3) a combination of $30 and
3.2 Deutsche Telekom ordinary shares, in each case subject to certain procedures
and limitations contained in the Deutsche Telekom/VoiceStream merger agreement
including, without limitation, limiting the cash consideration to a maximum
aggregate amount and to the right of VoiceStream to reduce such maximum
aggregate amount

                                       63
<PAGE>   82

as it reasonably determines necessary to permit delivery of the requisite tax
opinion pursuant to the Deutsche Telekom/VoiceStream merger agreement, as to
which procedures and limitations Goldman Sachs expressed no opinion.

     The full text of the Goldman Sachs opinion is attached as Annex D to this
proxy statement/ prospectus and stockholders of VoiceStream are urged to, and
should, read such opinion in its entirety.

     In connection with its opinion, Goldman Sachs reviewed, among other things:

     - the Deutsche Telekom/VoiceStream merger agreement;

     - the subscription agreement relating to the VoiceStream voting preferred
       shares purchased by Deutsche Telekom;

     - the annual reports to stockholders and annual reports on Form 10-K of
       VoiceStream and its predecessors for the four years ended December 31,
       1999;

     - certain interim reports to stockholders and quarterly reports on Form
       10-Q of VoiceStream;

     - the definitive proxy statement dated January 25, 2000, in connection with
       the acquisitions by VoiceStream of Aerial and Omnipoint;

     - the Forms 20-F of Deutsche Telekom for each of the three years ended
       December 31, 1999;

     - certain interim reports to stockholders of Deutsche Telekom;

     - the registration statement on Form F-3 of Deutsche Telekom, including the
       prospectus, dated July 17, 2000, related to Deutsche Telekom's offering
       of 200 million Deutsche Telekom ordinary shares;

     - the registration statement on Form F-3 of Deutsche Telekom, including the
       prospectus supplement, dated June 28, 2000, related to Deutsche Telekom's
       offering of $14.6 billion aggregate principal amount of notes;

     - other communications from VoiceStream and Deutsche Telekom to their
       respective stockholders; and

     - internal financial analyses and forecasts for VoiceStream prepared by the
       management of VoiceStream.

     Goldman Sachs also held discussions with members of the senior management
of VoiceStream and Deutsche Telekom regarding their assessment of the strategic
rationale for, and the potential benefits of, the Deutsche Telekom/VoiceStream
merger, and the past and current business operations, financial condition and
future prospects of their respective companies.

     In addition, Goldman Sachs:

     - reviewed the reported prices and trading activity for VoiceStream common
       shares and Deutsche Telekom ordinary shares;

     - compared certain financial and stock market information for VoiceStream
       and Deutsche Telekom with similar information for certain other companies
       the securities of which are publicly traded;

     - reviewed the financial terms of certain recent business combinations in
       the telecommunications industry specifically, and in other industries
       generally; and

     - performed such other studies and analyses as Goldman Sachs considered
       appropriate.

     Goldman Sachs understood that, in connection with the Deutsche
Telekom/VoiceStream merger agreement VoiceStream would issue (and since then
VoiceStream has issued) to Deutsche Telekom 3,906,250 shares of VoiceStream
voting preferred shares for aggregate consideration of $5 billion pursuant to
the voting preferred stock subscription agreement.

                                       64
<PAGE>   83

     Goldman Sachs relied upon the accuracy and completeness of all of the
financial and other information discussed with or reviewed by it, and assumed
such accuracy and completeness for purposes of rendering its opinion. As the
VoiceStream board of directors was aware, Deutsche Telekom did not make
available to Goldman Sachs its projections of expected future financial
performance. Accordingly, Goldman Sachs's review of such matters was limited to
discussions with members of the senior management of Deutsche Telekom regarding
certain research analyst estimates of future financial performance of Deutsche
Telekom. In addition, Goldman Sachs did not make an independent evaluation or
appraisal of the assets and liabilities of VoiceStream or Deutsche Telekom or
any of their subsidiaries, and Goldman Sachs was not furnished with any such
evaluation or appraisal. Goldman Sachs also assumed that all material
governmental, regulatory or other consents and approvals necessary for the
completion of the Deutsche Telekom/VoiceStream merger will be obtained without
any adverse effect on VoiceStream or Deutsche Telekom or on the expected
benefits of the Deutsche Telekom/VoiceStream merger. Goldman Sachs's advisory
services and opinion were provided for the information and assistance of the
VoiceStream board in connection with its consideration of the transaction
contemplated by the Deutsche Telekom/VoiceStream merger agreement, and the
opinion does not constitute a recommendation as to how any holder of VoiceStream
common shares should vote or which election to take with respect to the form of
merger consideration to be received in the Deutsche Telekom/VoiceStream merger.

     The following is a summary of the material financial analyses presented by
Goldman Sachs to the VoiceStream board of directors on July 21, 2000. Some of
the summaries of the financial analyses include information presented in tabular
format. The tables must be read together with the text accompanying each
summary.

  Analysis of VoiceStream

     Historical Exchange Ratio Analysis.  Goldman Sachs performed an analysis
the purpose of which was to compare the all-stock election exchange ratio and
the mixed election exchange ratio in the Deutsche Telekom/VoiceStream merger to
the ratio of the daily closing share prices of Deutsche Telekom ordinary shares
to corresponding prices for VoiceStream common shares on July 20, 2000, July 10,
2000 (the last trading day before any public reports of the proposed Deutsche
Telekom/VoiceStream merger) and the 10-day, 20-day, 30-day, 60-day, three-month,
six-month, nine-month and one-year periods ending July 20, 2000. In this
analysis, Deutsche Telekom share prices were converted to U.S. dollars based on
the noon buying rate of euros for U.S. dollars as reported by the Federal
Reserve System on the date indicated or averaged across the period measured.
This analysis indicated the following implied exchange ratios for these points
in time or periods, as compared with the all-stock election exchange ratio of
3.7647 and the mixed election exchange ratio of 3.2 in the Deutsche
Telekom/VoiceStream merger:

     Selected Companies Analysis.  Goldman Sachs performed an analysis the
purpose of which was to determine how different measures of the price per
VoiceStream POP represented by the Deutsche Telekom/VoiceStream merger
consideration compared both to VoiceStream's stand-alone price per POP
                                       65
<PAGE>   84

and the price per POP for the following selected companies: Nextel
Communications Inc., Powertel, TeleCorp PCS Inc. and Sprint PCS Group. POPs are
the number of persons within a license's coverage area and are derived from
management estimates and public sources. The selected companies were chosen
because they are publicly traded companies with operations that are similar to
those of VoiceStream. The price per POP, in each case, was calculated by
dividing the respective company's core enterprise value or adjusted enterprise
value by different measures of that company's POPs. In this analysis:

     - "Core enterprise value" for each of the companies is the sum of its
       market capitalization, total debt, preferred shares and minority
       interest, less cash, cash equivalents and an estimate of non-core assets.

     - "Adjusted enterprise value" for each company is the core enterprise value
       for that company less the value of unbuilt POPs, valued at $25.00 per
       POP.

     - "Covered POPs" are the estimated number of POPs within the license area
       served by the operating network.

     - "Weighted total POPs" are determined by multiplying the number of POPs in
       a 30 MHz license area by one, the number of POPs in a 20 MHz license area
       by 0.75, the number of POPs in a 10 MHz license area by 0.25 and, with
       respect to Nextel, the number of Nextel POPs by 0.75, and reflect the
       fact that licenses with greater MHz provide greater bandwidth or
       capacity.

     The analysis was performed using share prices as of July 20, 2000. Finally,
"2001 Covered POP Value" represents adjusted enterprise value divided by
projected 2001 Covered POPs, "Weighted total POP value" represents core
enterprise value divided by Weighted total POPs and "Total POP value" represents
core enterprise value divided by total, unadjusted POPs.

     The following chart summarizes the results of that analysis:

* VoiceStream valued at $199.63, which represented the value of 3.2 Deutsche
  Telekom shares plus $30 on July 20, 2000, based on a closing price per share
  of Deutsche Telekom stock of 57.05 euros and an exchange rate of 0.9292.

     Goldman Sachs also computed the implied price per VoiceStream common share
that would result if VoiceStream's 2001 Covered POP Value were valued at the
same price per POP as that of each of Sprint PCS, TeleCorp, Powertel and Nextel.
This was done by multiplying each company's 2001 Covered POP Value by
VoiceStream's projected 2001 Covered POPs, adding in VoiceStream's unbuilt
licenses and non-core assets and subtracting VoiceStream's net debt, and the
value of dividing that figure by the 271.3

     Discounted Cash Flow Analysis.  Goldman Sachs performed an analysis the
purpose of which was to compare the present value per VoiceStream common share,
using discounted cash flow methodologies, to the value per share represented by
the merger consideration. Goldman Sachs performed this analysis by determining
ranges of enterprise values and equity values for VoiceStream on a stand-alone
basis. Specifically, Goldman Sachs considered the range of values for
VoiceStream on a stand-alone basis based on VoiceStream management's internal
base case model for VoiceStream and VoiceStream management's internal growth
model for VoiceStream. The following tables present the ranges of enterprise
values and equity values, as well as the price per share and the ratio of
enterprise value to 2001 Covered POPs for both of the VoiceStream cases, based
on forward 2009 EBITDA multiples for VoiceStream ranging from 10.0x to 12.0x and
discount rates ranging from 11% to 12%. Equity value represents VoiceStream's
enterprise value net of the book value of VoiceStream's outstanding net
indebtedness and estimated non-core assets.

     "EBITDA" stands for earnings before interest, taxes, depreciation and
amortization.

figures represented by other selected transactions or proposed transactions in
the wireless industry. Goldman Sachs measured the premium represented by the
merger consideration and the VoiceStream price per POP based on July 20, 2000
stock prices, and compared the premiums and price per POP in the following

  Analysis of Deutsche Telekom

     Sum-of-the-Parts Analysis.  Goldman Sachs performed an analysis the purpose
of which was to determine a range of values for Deutsche Telekom based on the
values of the five major business units of Deutsche Telekom. The five units of
Deutsche Telekom analyzed by Goldman Sachs were:

     - wireless operations;

     - traditional fixed-line telecommunications operations;

     - Internet operations;

     - data communications operations; and

     - miscellaneous other investments.

     The following table presents the low, high, median and current equity value
and equity value per share for Deutsche Telekom based on that analysis:

</TABLE>

     Goldman Sachs used discounted cash flow methodologies and EBITDA multiples
to value Deutsche Telekom's wireless operations and discounted cash flow
methodologies and revenue and enterprise value multiples to value its
traditional fixed-line telecommunications operations. With respect to Deutsche
Telekom's Internet operations, Goldman Sachs based its analysis on market
valuations for Deutsche Telekom's publicly traded Internet subsidiary, T-Online.
Finally, for data communications and miscellaneous other investments, Goldman
Sachs used various valuation methodologies, including revenue multiples, market
values for certain public investments and acquisition price or book value for
other investments.

     The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description. Selecting
portions of the analysis or of the summary set forth above, without considering
the analyses as a whole, could create an incomplete view of the processes
underlying Goldman Sachs's opinion. In arriving at its fairness determination,
Goldman Sachs considered the results of all such analyses. No company or
transaction used in the above analyses as a comparison is directly comparable to
VoiceStream or Deutsche Telekom or the Deutsche Telekom/VoiceStream merger.
Goldman Sachs prepared the analyses solely for purposes of providing its opinion
to the VoiceStream board as to the fairness of the merger consideration in
aggregate to be received by holders of VoiceStream common shares. The analyses
do not purport to be appraisals or to necessarily reflect the prices at which
the business or securities actually may be sold. Analyses based upon forecasts
of future results, which are

                                       68

inherently subject to uncertainty, are not necessarily indicative of actual
future results, which may be significantly more or less favorable than suggested
by such analyses.

     Goldman Sachs, as part of its investment banking business, is continually
engaged in the valuation of businesses and their securities in connection with
mergers and acquisitions, negotiated underwritings, competitive biddings,
secondary distributions of listed and unlisted securities, private placements
and valuations for estate, corporate and other purposes. VoiceStream selected
Goldman Sachs as its financial advisor because it is a nationally recognized
investment banking firm that has substantial experience in transactions similar
to the Deutsche Telekom/VoiceStream merger and because of Goldman Sachs'
familiarity with VoiceStream arising from having provided investment banking
services in the past to VoiceStream and its predecessor.

     Goldman Sachs is familiar with VoiceStream, having provided certain
investment banking services, from time to time, to (1) VoiceStream, (2)
VoiceStream's predecessor, VoiceStream Wireless Corporation, a Washington
corporation and (3) VoiceStream Washington's former parent, Western Wireless
including having acted as:

     - lead managing underwriter in the initial public offering of 12.65 million
       Western Wireless common shares in May 1996;

     - lead manager in the public offering of $200 million aggregate principal
       amount of 10.5% senior subordinated notes due June 2006 of Western
       Wireless in May 1996;

     - lead manager in the private offering of $200 million aggregate principal
       amount of 10.5% senior subordinated notes due February 2007 of Western
       Wireless in October 1996;

     - Western Wireless's financial advisor in connection with the sale of 19.9%
       of the outstanding VoiceStream Washington common shares to Hutchison PCS
       (USA) Limited in February 1998;

     - lead manager in the secondary public offering of 13.915 million shares of
       Western Wireless common shares in April 1998;

     - VoiceStream's financial advisor in connection with the acquisition of
       Omnipoint in June 1999;

     - VoiceStream's financial advisor in connection with the acquisition of
       Aerial in September 1999;

     - lead manager in the private offering of $1.1 billion aggregate principal
       amount of 10 3/8% senior notes due November 2009 of VoiceStream
       Washington and VoiceStream and $720 million aggregate principal amount of
       11 7/8% senior discount notes due November 2009 of VoiceStream Washington
       and VoiceStream in November 1999; and

     - VoiceStream's financial advisor in connection with, and having
       participated in certain of the negotiations leading to, the Deutsche
       Telekom/VoiceStream merger agreement.

As of July 23, 2000, investment funds affiliated with Goldman Sachs had a
principal investment in VoiceStream in the amount of 10,088,128 VoiceStream
common shares and the right to designate a nominee for election to the
VoiceStream board of directors. Terrence O'Toole, a managing director of Goldman
Sachs, is a director of VoiceStream. From time to time, Goldman Sachs also has
provided, and is currently providing, significant investment banking services to
Deutsche Telekom, including having acted as:

     - co-lead manager in the initial public offering of 714 million Deutsche
       Telekom ordinary shares in November 1996;

     - co-lead manager in the public offering of 250 million Deutsche Telekom
       ordinary shares in June 1999;

     - financial advisor to Deutsche Telekom in the acquisition of One 2 One
       Ltd. in July 1999;

     - co-lead manager in the initial public offering of 114 million shares of
       T-Online common shares in April 2000;
                                       69
<PAGE>   88

     - co-lead manager in the public offering of 200 million Deutsche Telekom
       ordinary shares in June 2000;

     - co-lead manager in the public offering of $14.6 billion aggregate
       principal amount of notes (due at various maturity dates) of Deutsche
       Telekom in June 2000, and may provide investment banking services to
       Deutsche Telekom in the future.

Goldman Sachs provides a full range of financial advisory and securities
services, and, in the course of its normal trading activities, may, from time to
time, effect transactions and hold securities, including derivative securities,
of VoiceStream and Deutsche Telekom for its own account and for the accounts of
customers. As of July 21, 2000, Goldman Sachs had accumulated a net long
position of 1,178,796 Deutsche Telekom ordinary shares. As of the same date and
not including the principal investment referred to above, Goldman Sachs had a
net short position of 108,848 VoiceStream common shares.

     Pursuant to a letter agreement dated July 21, 2000, VoiceStream engaged
Goldman Sachs to act as its financial advisor in connection with a potential
transaction involving Deutsche Telekom. Pursuant to this letter agreement,
VoiceStream paid Goldman Sachs $10 million on completion of the sale of
VoiceStream voting preferred shares to Deutsche Telekom on September 6, 2000,
and has agreed to pay Goldman Sachs an additional $15 million on the date
VoiceStream stockholders vote to adopt the Deutsche Telekom/VoiceStream merger
agreement. VoiceStream also has agreed to pay Goldman Sachs a transaction fee
equal to $70 million upon completion of the Deutsche Telekom/VoiceStream merger,
against which transaction fee the $25 million paid in accordance with the
preceding sentence will be credited. VoiceStream has agreed to reimburse Goldman
Sachs for its reasonable out-of-pocket expenses, including attorneys' fees, and
to indemnify Goldman Sachs against certain liabilities, including certain
liabilities under the U.S. federal securities laws.

PLANS FOR VOICESTREAM AFTER THE DEUTSCHE TELEKOM/VOICESTREAM MERGER

     Following the Deutsche Telekom/VoiceStream merger, VoiceStream will become
a wholly-owned subsidiary of Deutsche Telekom. Deutsche Telekom's current plan
is to contribute its shares of VoiceStream after the Deutsche
Telekom/VoiceStream merger to its wholly-owned subsidiary T-Mobile.

INTERESTS OF DIRECTORS AND OFFICERS OF VOICESTREAM IN THE DEUTSCHE
TELEKOM/VOICESTREAM MERGER

     Some of the directors and officers of VoiceStream have interests in the
Deutsche Telekom/VoiceStream merger that are different from, or in addition to,
the interests of VoiceStream stockholders generally. These interests, to the
extent material, are described below. The VoiceStream board was aware of these
interests and considered them in approving the Deutsche Telekom/VoiceStream
merger agreement and the Deutsche Telekom/VoiceStream merger.

     Treatment of Equity Awards.

     The Deutsche Telekom/VoiceStream merger agreement provides that immediately
prior to the completion of the Deutsche Telekom/VoiceStream merger, each
outstanding option to purchase VoiceStream common shares will be converted into
the right to acquire Deutsche Telekom ordinary shares. The treatment of
VoiceStream options is described in greater detail under "The Deutsche
Telekom/VoiceStream Merger Agreement -- Treatment of VoiceStream Stock Plans."
Except as provided below, upon stockholder approval of the Deutsche
Telekom/VoiceStream merger by the stockholders of VoiceStream, each outstanding
option to purchase VoiceStream common shares held by the executive officers of
VoiceStream will, by its terms, to the extent not already vested, become
immediately fully vested and exercisable (other than the unvested options held
by Robert R. Stapleton, VoiceStream's president, Donald Guthrie, VoiceStream's
vice chairman, Cregg B. Baumbaugh, VoiceStream's executive vice
president -- finance, strategy and development, and Alan R. Bender,
VoiceStream's executive vice president, general counsel and secretary, each of
whom has waived the acceleration of the vesting of their options). In addition,
the VoiceStream board has discretion to vest the outstanding restricted shares
held by the VoiceStream executive officers, except for the outstanding
restricted shares of VoiceStream

                                       70
<PAGE>   89

common shares granted to Messrs. Stapleton, Baumbaugh, Guthrie and Bender that
are described in the following sentence. On July 21, 2000, the board of
directors of VoiceStream granted 127,871 restricted VoiceStream common shares to
Mr. Stapleton, 51,475 restricted VoiceStream common shares to Mr. Baumbaugh,
69,725 restricted VoiceStream common shares to Mr. Guthrie and 43,048 restricted
VoiceStream common shares to Mr. Bender. Neither the grant of such restricted
shares nor the vesting of such restricted shares was or is contingent upon the
Deutsche Telekom/VoiceStream merger in any way. The restricted shares will vest
and no longer be subject to restriction upon VoiceStream reaching certain
performance targets relating to subscriber enrollment.

     Retention Plan

     Prior to the completion of the Deutsche Telekom/VoiceStream merger,
VoiceStream may implement a "stay bonus plan" for management, including the
executive officers of VoiceStream. Pursuant to the stay bonus plan, each person
employed by VoiceStream as of July 23, 2000, would receive a $3,000 cash bonus
three months following the completion of the Deutsche Telekom/VoiceStream merger
if they remain employed in good standing as of that date. In addition,
approximately 500 to 1,000 management employees of VoiceStream, including the
executive officers of VoiceStream, would be eligible to receive cash bonuses
equal to up to two years' base salary that would be paid as follows: 33.3% of
the cash bonus would be paid 90 days after the completion of the Deutsche
Telekom/VoiceStream merger, 33.3% of the cash bonus would be paid on the first
anniversary of the Deutsche Telekom/VoiceStream merger and 33.4% of the cash
bonus will be paid on the second anniversary of the Deutsche Telekom/VoiceStream
merger to those employees who remain employed in good standing on those dates.
Upon a participant's termination of employment as a result of a reduction in
force, termination without cause, death, disability or a constructive
termination due to a reduction in base pay, the participant will be paid his
remaining unpaid cash bonus in a lump sum.

     In addition, Deutsche Telekom and VoiceStream agreed to cooperate to
develop a mutually acceptable retention plan for senior management employees of
VoiceStream.

     Tax Reimbursement Payments

     If any VoiceStream employees, including executive officers, become subject
to the excise tax under Section 4999 of the U.S. tax code, VoiceStream may
provide to those employees tax reimbursement payments for the excise tax. The
aggregate amount of such payments to all employees is limited to $20 million.

     Indemnification of Directors and Officers

     Deutsche Telekom has agreed to cause the surviving corporation in the
Deutsche Telekom/VoiceStream merger to maintain, for a period of six years after
the completion of the Deutsche Telekom/VoiceStream merger, VoiceStream's current
provisions and policies regarding indemnification of officers and directors,
provided that the surviving corporation may substitute policies having at least
the same coverage and containing terms that are no less advantageous to the
insured. If the premium for such policies or substitute policies would otherwise
exceed 250% of the current premium, the surviving corporation need only obtain
as much insurance as can be obtained for 250% of the current premium. In
addition, Deutsche Telekom and VoiceStream have agreed to indemnify the officers
and directors of VoiceStream to the fullest extent permitted by law. For more
information, see "Summary of the Deutsche Telekom/VoiceStream Transaction
Documents -- The Deutsche Telekom/VoiceStream Merger
Agreement -- Indemnification and Insurance."

     Stockholder Agreements

     In connection with the execution of the Deutsche Telekom/VoiceStream merger
agreement, a number of VoiceStream stockholders and their respective affiliates
entered into agreements with Deutsche Telekom regarding the voting and transfer
of all or a portion of their VoiceStream shares subject to such

                                       71
<PAGE>   90

agreements. Some of these stockholders are, or have relationships with,
directors or executive officers of VoiceStream, as follows:

     - John W. Stanton, chairman and chief executive officer and director;

     - Douglas G. Smith, vice chairman and director;

     - Hutchison Whampoa Limited, which is the employer of directors Susan M.F.
       Woo Chow, Canning K.N. Fok and Frank J. Sixt;

     - Sonera Corporation, which is the employer of director Kaj-Erik Relander;

     - Goldman Sachs, which is the employer of director Terrence M. O'Toole;

     - Madison Dearborn Capital Partners, LP, which is the employer of director
       James N. Perry; and

     - Allen & Company Incorporated, which is the employer of director Richard
       L. Fields.

     We describe these stockholder agreements in greater detail under "Summary
of the Deutsche Telekom/VoiceStream Transaction Documents -- Deutsche Telekom's
Agreements with Stockholders of VoiceStream."

APPRAISAL RIGHTS

     Delaware law entitles the holders of record of VoiceStream common shares
and VoiceStream voting preferred shares that follow the procedures specified in
Section 262 of the Delaware corporation law to have their shares appraised by
the Delaware Court of Chancery and to receive the "fair value" of these
VoiceStream shares as of the completion of the Deutsche Telekom/VoiceStream
merger as determined by the court in place of the merger consideration. In order
to exercise such rights, a stockholder must demand and perfect the rights in
accordance with Section 262. The following is a summary of Section 262 and is
qualified in its entirety by reference to Section 262, a copy of which is
attached as Annex G to this proxy statement/prospectus. Stockholders should
carefully review Section 262 as well as the information discussed below to
determine their rights to appraisal.

     Because all of the outstanding VoiceStream voting preferred shares are
owned by Deutsche Telekom, and Deutsche Telekom intends to vote these shares in
favor of the Deutsche Telekom/VoiceStream merger, the following discussion of
Section 262 addresses the rights and obligations of only the holders of
VoiceStream common shares.

     If a holder of VoiceStream common shares elects to exercise the right to an
appraisal under Section 262, that VoiceStream stockholder must do all of the
following:

      (1) file with VoiceStream at its main office in Bellevue, Washington, a
          written demand for appraisal of VoiceStream common shares held, which
          demand must identify the VoiceStream stockholder and expressly request
          an appraisal, before the vote is taken on the Deutsche Telekom/
          VoiceStream merger agreement at the VoiceStream special meeting (this
          written demand for appraisal must be in addition to and separate from
          any proxy or vote against the Deutsche Telekom/VoiceStream merger
          agreement; neither voting against or abstaining from voting nor
          failing to vote on the Deutsche Telekom/VoiceStream merger agreement
          will constitute a demand for appraisal within the meaning of Section
          262);

      (2) not vote in favor of, or consent in writing to, the Deutsche
          Telekom/VoiceStream merger agreement (failing to vote or abstaining
          from voting will satisfy this requirement, but a vote in favor of the
          Deutsche Telekom/VoiceStream merger agreement, by proxy or in person,
          or the return of a signed proxy card that does not specify a vote
          against approval and adoption of the Deutsche Telekom/VoiceStream
          merger agreement, will constitute a waiver of the VoiceStream
          stockholder's right of appraisal and will nullify any previously filed
          written demand for appraisal); and

     (3) continuously hold such shares through the completion of the Deutsche
         Telekom/VoiceStream merger.

                                       72

     All written demands for appraisal should be addressed to VoiceStream
Wireless Corporation, 3650 131(st) Avenue SE, Bellevue, Washington 98006,
Attention: General Counsel, before the vote is taken on the Deutsche
Telekom/VoiceStream merger agreement at the VoiceStream special meeting, and
should be executed by, or on behalf of, the holder of record of the relevant
VoiceStream common shares. This demand must reasonably inform VoiceStream of the
identity of the stockholder and that the stockholder is thereby demanding
appraisal of the stockholder's VoiceStream common shares.

     Within 10 days after the completion of the Deutsche Telekom/VoiceStream
merger, the surviving corporation of the Deutsche Telekom/VoiceStream merger
will give written notice of the completion of the Deutsche Telekom/VoiceStream
merger to each VoiceStream stockholder that has satisfied the requirements of
Section 262 and has not voted for or consented to the proposal to approve and
adopt the Deutsche Telekom/VoiceStream merger agreement and the transactions
contemplated by the Deutsche Telekom/VoiceStream merger agreement (a "dissenting
stockholder"). Within 120 days after the completion of the Deutsche
Telekom/VoiceStream merger, the surviving corporation or any dissenting
stockholder may file a petition in the court demanding a determination of the
fair value of the VoiceStream common shares that are held by all dissenting
stockholders. We advise any dissenting stockholder desiring to file this
petition to file such petition on a timely basis unless the dissenting
stockholder receives notice that a petition has already been filed by the
surviving corporation or another dissenting stockholder.

     If a petition for appraisal is timely filed, the court will determine which
stockholders are entitled to appraisal rights. The court then will determine the
fair value of the VoiceStream common shares held by the dissenting stockholders,
exclusive of any element of value arising from the accomplishment or expectation
of the Deutsche Telekom/VoiceStream merger, but together with a fair rate of
interest, if any, to be paid on the amount determined to be fair value. In
determining the fair value, the court will take into account all relevant
factors. The court may determine the fair value to be more than, less than or
equal to the consideration that the dissenting stockholder would otherwise be
entitled to receive under the Deutsche Telekom/VoiceStream merger agreement. If
a petition for appraisal is not timely filed, then the right to an appraisal
will cease. The costs of the appraisal proceeding may be determined by the court
and charged against the parties as the court determines to be equitable under
the circumstances. Upon the application of any stockholder, the court may
determine the amount of interest, if any, to be paid upon the value of the
VoiceStream common shares of stockholders entitled to such interest. 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 attorneys' fees and the
fees and expenses of experts, to be charged pro rata against the value of all
shares of VoiceStream common shares entitled to appraisal.

     From and after the completion of the Deutsche Telekom/VoiceStream merger,
no dissenting stockholder will have any rights of a VoiceStream stockholder with
respect to that dissenting stockholder's shares for any purpose, except to
receive payment of its fair value and to receive payment of dividends or other
distributions on that dissenting stockholder's VoiceStream common shares, if
any, payable to VoiceStream stockholders of record as of a date prior to the
completion of the Deutsche Telekom/VoiceStream merger. If a dissenting
stockholder delivers to the surviving corporation a written withdrawal of the
demand for an appraisal within 60 days after the completion of the Deutsche
Telekom/ VoiceStream merger or, if no petition for appraisal is filed within 120
days after the completion of the Deutsche Telekom/VoiceStream merger, then the
right of that Dissenting Stockholder to an appraisal will cease and the
dissenting stockholder will be entitled to receive only the merger
consideration.

                  THE DEUTSCHE TELEKOM/POWERTEL MERGER AND THE
                          VOICESTREAM/POWERTEL MERGER

BACKGROUND OF DEUTSCHE TELEKOM/POWERTEL MERGER AND VOICESTREAM/POWERTEL MERGER

     Deutsche Telekom - General Background

     Deutsche Telekom has been seeking to expand internationally through
acquisitions, investments and joint undertakings in the areas that are the four
pillars of its growth strategy: mobile telecommunications, data/IP/systems,
consumer Internet services and network access services. Deutsche Telekom
considers expansion of its international business to be an essential component
of its overall business strategy. In particular, Deutsche Telekom has aimed to
build on its strength in Europe and to expand its reach in the United States.
From time to time, Deutsche Telekom has engaged and may continue to engage in
discussions with other parties that may lead to one or more substantial
cross-border acquisitions or business combinations. In that connection, Deutsche
Telekom retained Donaldson, Lufkin & Jenrette and Dresdner Kleinwort Benson in
November 1999 as financial advisors to advise it on acquisition alternatives in
the U.S. wireless telecommunications industry. Over the next several months,
Deutsche Telekom, with the aid of Donaldson Lufkin & Jenrette and Dresdner
Kleinwort Benson, explored several wireless opportunities in the United States,
including an acquisition of VoiceStream. Among other things, Deutsche Telekom
and its financial advisors analyzed the U.S. wireless market, possible
valuations of VoiceStream and alternative transaction structures and
considerations.

     VoiceStream - General Background

     Following the spin-off of VoiceStream from Western Wireless in May 1999,
VoiceStream's board of directors has sought to expand the geographic scope of,
and enhance the services provided by, its wireless business operations to enable
VoiceStream to become a nationwide service provider and to compete effectively
against larger wireless carriers. In late 1999 and the first half of 2000,
VoiceStream acquired wireless carriers Omnipoint and Aerial, received a $957
million investment from Hutchison Whampoa, a $500 million investment from
Sonera, entered into a new $3.25 billion credit agreement and raised $1.46
billion in a high-yield debt offering.

     As a result of these acquisitions and financing activities, by the end of
the first half of 2000, VoiceStream had become a national competitor in the U.S.
wireless communications industry. VoiceStream's board of directors and
management believed that VoiceStream's size and financial resources relative to
other national competitors, and the conditions and trends in the
telecommunications industry, including the on-going consolidation of
telecommunications companies both in the United States and globally, would
require VoiceStream to continue to expand if VoiceStream were to remain a strong
competitor in the wireless telecommunications industry.

     Powertel - General Background

     During the past several years, the Powertel board of directors has
considered various options and has authorized various transactions in an effort
to maximize stockholder value. In 1997, Powertel sold its cellular assets in the
state of Maine, and in 1999 Powertel sold its cellular assets in the states of
Georgia and Alabama in order to focus its efforts on its PCS operations. Also in
1999, Powertel sold 650 of its telecommunications towers in order to take
advantage of the prices that were then available for telecommunications towers.
During this period, the Powertel board of directors continued to monitor market
developments, including the ongoing consolidation in the wireless
telecommunications industry and the trend toward nationwide coverage and rate
plans. In connection with these developments, the Powertel board of directors
considered various strategies for expanding Powertel's coverage area, and as a
result Powertel committed to make an equity investment in Eliska Wireless
Ventures I, Inc. in order to enable Eliska Wireless Ventures to purchase DiGiPH
PCS, which has a coverage area that is contiguous with Powertel's. Powertel also
began to contact a number of other parties regarding the possibility of an
acquisition, investment or strategic alliance.

     The Deutsche Telekom/Powertel Merger and the VoiceStream/Powertel Merger

     On October 13, 1999, Allen E. Smith, president and chief executive officer
of Powertel, Fred G. Astor, Jr., chief financial officer of Powertel, Rodney D.
Dir, chief operating officer of Powertel, and Campbell B. Lanier, III, chairman
of the Powertel board of directors, met with John W. Stanton, chairman and chief
executive officer of VoiceStream, Robert R. Stapleton, president of VoiceStream,
and Cregg B. Baumbaugh, executive vice president of finance, strategy &
development of VoiceStream, in Seattle, Washington. The parties discussed
possible strategic alliances between Powertel and VoiceStream. At that time,
VoiceStream's mergers with Omnipoint and Aerial were pending. Mr. Stanton
indicated that VoiceStream would be unable to engage in serious discussions
regarding strategic alliances between Powertel and VoiceStream until after the
closing of those mergers.

     On February 29, 2000, Mr. Smith and Mr. Astor met with Mr. Stanton and Mr.
Baumbaugh at the CTIA Wireless Convention in New Orleans, Louisiana. The
parties' discussions focused on a potential investment by VoiceStream in
Powertel, which could be followed by an acquisition of Powertel by VoiceStream.
The parties also discussed the possibility that a third party might make an
additional investment in Powertel.

     On March 9, 2000, VoiceStream and Powertel executed a non-disclosure
agreement. On March 10, 2000, Mr. Smith and Mr. Stanton spoke by telephone. They
discussed the fact that a Powertel stockholder had expressed an interest in
selling its Powertel shares. Mr. Stanton indicated that VoiceStream might be
interested in purchasing these shares. The parties also discussed the
possibility of a third party acquiring these shares. Also, on March 10, 2000,
representatives of Powertel met with representatives of this third party to
discuss a direct investment by this party in Powertel, a purchase by this party
of the selling stockholder's interest and the potential acquisition of Powertel
by this third party.

     On March 13, 2000, Mr. Smith, Mr. Lanier and Mr. Stanton spoke by telephone
to further discuss the possibility of VoiceStream purchasing shares from a
Powertel stockholder, possibly to be followed by an acquisition of Powertel.

     On March 16, 2000, Mr. Smith, Mr. Astor, Mr. Stanton, Mr. Stapleton and Mr.
Baumbaugh met in Phoenix, Arizona to further discuss these matters. At this
meeting, the parties again discussed the possibility of VoiceStream making a
direct investment in Powertel.

     Later in March 2000, Mr. Stanton informed Mr. Smith, by telephone, that due
to certain unspecified conflicts, VoiceStream was not in a position to proceed
with discussions with Powertel.

     During April and May 2000, members of Powertel's management and members of
the Powertel board of directors discussed various strategic alternatives
available to Powertel, including a possible strategic combination of Powertel
with a U.S. or international telecommunications company. Based upon a consensus
view that Powertel should explore a range of strategic alternatives,
representatives of Powertel contacted Morgan Stanley, which Powertel had
previously engaged, and asked that Morgan Stanley prepare a presentation
regarding methods by which Powertel could explore its strategic alternatives,
including a possible strategic business combination.

     On May 22, 2000, Morgan Stanley made a presentation to members of the
Powertel board of directors and certain members of Powertel's management
regarding a proposed process for soliciting indications of interest from parties
that might be interested in engaging in a strategic transaction with Powertel.
The process outlined by Morgan Stanley involved soliciting preliminary
indications of interest from a list of potentially interested companies,
followed by a distribution of informational materials to these parties and a
solicitation of final indications of interest. Representatives of Powertel
reviewed a list of companies that Morgan Stanley believed potentially would be
interested in pursuing discussions with Powertel. Morgan Stanley was instructed
to proceed to contact these parties.

     On June 15, 2000, Morgan Stanley provided an update to members of the
Powertel board and management regarding the status of contacts with potentially
interested parties. As of that date, Morgan Stanley had contacted eight
companies, had received preliminary oral indications of interest from three

                                       75
<PAGE>   94

companies, had received no response from two companies and had received a
negative response from three companies.

     During the course of Deutsche Telekom's due diligence review of VoiceStream
that took place in Seattle, Washington on June 27 through June 29, 2000,
VoiceStream informed Deutsche Telekom of its intention to commence discussions
with Powertel concerning a possible acquisition of Powertel by VoiceStream.

     On June 28, 2000, VoiceStream submitted a preliminary written indication of
interest that contemplated an acquisition of Powertel in a stock-for-stock
transaction at a value of $85 per share of Powertel stock, which implied a fixed
exchange ratio of .675 of a VoiceStream common share for each Powertel common
share.

     On July 12, 2000, the Powertel board of directors held a special meeting to
discuss the status of the process being conducted by Morgan Stanley. After
receiving an update on the status of this process, the Powertel board of
directors authorized Morgan Stanley to continue the process.

     On July 13 and 14, 2000, several representatives of VoiceStream's
management team and VoiceStream's outside counsel conducted due diligence in
Atlanta, Georgia. These due diligence meetings involved general presentations by
members of Powertel's management, followed by numerous smaller meetings between
representatives of the companies responsible for specific functional areas.
Also, during these meetings, representatives of Powertel and VoiceStream
discussed the terms of VoiceStream's preliminary indication of interest.

     During the week of July 17, 2000, VoiceStream and Deutsche Telekom
discussed the possibility of proceeding with an acquisition of Powertel in
conjunction with Deutsche Telekom's proposed acquisition of VoiceStream.

     On July 18, 2000, VoiceStream distributed a draft merger agreement to
Powertel. On July 19, 2000, however, Mr. Baumbaugh informed Mr. Smith and Mr.
Astor, by telephone, that VoiceStream was involved in another unspecified
potential transaction, and that VoiceStream would not be in a position to
continue discussions with Powertel until VoiceStream had completed its
discussions with respect to the other potential transaction. Thereafter,
Powertel confirmed to VoiceStream, through Morgan Stanley, that the process that
Morgan Stanley was conducting would proceed and that final indications of
interest were due on August 4, 2000.

     On July 19, 2000, in connection with the process initiated by Morgan
Stanley, Powertel distributed its form of merger agreement to VoiceStream.

     On July 21, 2000, VoiceStream and Deutsche Telekom signed an agreement to
allow VoiceStream to disclose the identity of its potential acquiror to
Powertel. Thereafter, VoiceStream disclosed to Powertel that its potential
acquiror was Deutsche Telekom. Deutsche Telekom and VoiceStream subsequently
decided not to proceed with the acquisition of Powertel until after announcing
the acquisition of VoiceStream by Deutsche Telekom.

     On July 24, 2000, VoiceStream publicly announced that it had agreed to
merge with Deutsche Telekom.

     On or about July 24, 2000, representatives of the third party that had been
considering an acquisition of Powertel informed representatives of Powertel that
they would not be pursuing discussions regarding a possible strategic
combination with Powertel.

     On July 25, 2000, Morgan Stanley, on behalf of Powertel, distributed a
final bid package to VoiceStream, including draft schedules to the merger
agreement that was distributed on July 19, 2000 and indicated that final
indications of interest were due by August 4, 2000.

     On August 4, 2000, VoiceStream submitted a final indication of interest
with respect to the acquisition of Powertel, including forms of transaction
documents between VoiceStream and Powertel. This proposal contemplated that
Powertel would enter into separate merger agreements with VoiceStream and
                                       76
<PAGE>   95

Deutsche Telekom, and it included proposed terms of a VoiceStream/Powertel
transaction and a Deutsche Telekom/Powertel transaction. This proposal
contemplated that Powertel stockholders holding the requisite voting power
necessary to approve the transactions would agree to vote their Powertel shares
in favor of the transactions, and representatives of Deutsche Telekom and
VoiceStream later indicated to representatives of Powertel that Deutsche Telekom
and VoiceStream would not enter into merger agreements with Powertel unless
Powertel stockholders holding a majority of the voting power necessary to
approve the Deutsche Telekom/Powertel merger and the VoiceStream/Powertel merger
agreed to vote in favor of these mergers. This proposal, which was subject to
satisfactory completion of due diligence, was to remain in effect until August
11, 2000. No party other than VoiceStream submitted final indications of
interest by the August 4, 2000 deadline.

     On August 8, 2000, the Powertel board held a special meeting to discuss the
VoiceStream proposal and the status of the process that was being conducted by
Morgan Stanley. The Powertel board reviewed the terms of the VoiceStream
proposal, including the proposed exchange ratios applicable to a transaction
with VoiceStream and Deutsche Telekom. At this meeting, Morgan Stanley made a
presentation to the Powertel board with respect to valuations of various
wireless telecommunications companies based on licensed POPs, covered POPs and
subscribers. The Powertel board authorized officers of Powertel to proceed with
negotiations with Deutsche Telekom and VoiceStream.

     On August 9, 2000, Mr. Baumbaugh, Alan Bender, general counsel of
VoiceStream, and representatives of Goldman Sachs, financial advisors to
VoiceStream, met in Denver, Colorado, with Mr. Smith, Jill Dorsey, general
counsel of Powertel, and representatives of Morgan Stanley. At this meeting, the
parties discussed outstanding issues with respect to the proposed transaction,
including a proposal that the exchange ratio be structured to yield $85 per
Powertel common share if VoiceStream common shares were trading between a
specified range prior to the completion of the VoiceStream/Powertel merger.

     On August 10, 2000, the Powertel board of directors held a special meeting
at which Mr. Smith provided an update on the status of the VoiceStream and
Deutsche Telekom negotiations. At this meeting, the Powertel board approved the
general terms of the VoiceStream and Deutsche Telekom proposals, as negotiated,
and authorized officers of Powertel to proceed with the negotiations of
definitive agreements.

     On August 12, 2000, Deutsche Telekom delivered forms of the Deutsche
Telekom/Powertel transaction agreements to Powertel and its counsel.

     From August 15 through August 17, 2000, representatives of VoiceStream,
Deutsche Telekom and Powertel, and their respective counsel, held a series of
meetings in Atlanta, Georgia to conduct further due diligence and negotiate
definitive documentation.

     On August 18, 2000, members of Powertel's management met with
representatives of VoiceStream in Bellevue, Washington to conduct due diligence
and to discuss issues related to the proposed transaction.

     On August 21 and 22, Mr. Smith and Mr. Dir conducted due diligence at the
offices of Deutsche Telekom in Bonn, Germany.

     During the period of August 21 to August 26, 2000, representatives of
VoiceStream, Deutsche Telekom and Powertel met in Seattle, Washington to
continue negotiations with respect to definitive documentation.

     On August 24, 2000, VoiceStream held a special meeting of the VoiceStream
board of directors. Mr. Stanton reviewed the strategic reasons for the proposed
VoiceStream/Powertel merger and senior management members of VoiceStream and
outside counsel presented further details regarding the transaction and reviewed
the terms of the definitive VoiceStream/Powertel merger agreement. Goldman Sachs
also presented a financial analysis of the proposed transaction and delivered
its oral opinion, later confirmed in writing, that as of the date of the
opinion, the conversion number under the VoiceStream/Powertel merger agreement
was fair from a financial point of view to VoiceStream. The presentation of
Goldman Sachs is described below under "-- Opinion of VoiceStream's Financial
Advisor." Mr. Stanton
                                       77
<PAGE>   96

informed the VoiceStream board that the only outstanding issues were minor and
were expected to be resolved. After such presentation and discussions, including
the matters set forth in "Risk Factors Relating to the VoiceStream/Powertel
Mergers," "-- VoiceStream's Reasons for the VoiceStream/Powertel Merger" and
"-- Recommendation and Considerations of the VoiceStream Board of Directors with
Respect to the VoiceStream/Powertel Merger," the VoiceStream board of directors
unanimously determined, subject to the successful resolution of the remaining
employment issues, that the VoiceStream/Powertel merger agreement and the
VoiceStream/Powertel merger were fair to, and in the best interests of,
VoiceStream and its stockholders and unanimously voted to approve the
VoiceStream/ Powertel merger agreement and the VoiceStream/Powertel merger and
related agreements and to recommend to VoiceStream stockholders that they vote
to approve the VoiceStream/Powertel merger agreement and the
VoiceStream/Powertel merger.

     Deutsche Telekom's management board discussed a potential acquisition
transaction involving Powertel at regularly scheduled meetings during July and
August 2000. On August 24, 2000, Deutsche Telekom's supervisory board met in
Bonn, Germany to consider the proposed acquisition of Powertel. At this meeting,
the supervisory board approved and authorized the execution of the Deutsche
Telekom/Powertel merger agreement, subject to finalization by the parties'
management and respective legal advisors.

     On August 24, 2000, a special meeting of the Powertel board of directors
was convened. At this meeting, members of Powertel's management and Powertel's
legal and financial advisors reviewed with the Powertel board the terms of the
VoiceStream/Powertel and Deutsche Telekom/Powertel merger agreements and
reported on the status of the negotiations. Morgan Stanley made a presentation
regarding the analysis described below under "-- Opinion of Powertel's Financial
Advisor." The potential benefits of the proposed transactions and the financial
and other effects of the proposed transactions were discussed in detail. Mr.
Smith reported to the Powertel board that key issues remained unresolved and
asked for a recess of the meeting until such issues could be further negotiated.
The Powertel board of directors voted to recess the meeting. On August 26, 2000,
the Powertel board reconvened this meeting. Mr. Smith reported to the Powertel
board regarding the proposed resolution of the outstanding issues, and legal
counsel reported to the Powertel board with regard to the terms of the
definitive VoiceStream/Powertel merger agreement and the Deutsche
Telekom/Powertel merger agreement, copies of which had previously been
distributed to the Powertel board. After these discussions, Morgan Stanley
rendered its oral opinion, which was subsequently confirmed in writing, that, as
of the date of the opinion, the consideration to be received by the holders of
the Powertel common and preferred shares pursuant to the Deutsche Telekom/
Powertel merger agreement was fair, from a financial point of view, to such
holders and, in the event the Deutsche Telekom/Powertel merger is not completed,
the merger consideration to be received by the holders of the Powertel common
and preferred shares pursuant to the VoiceStream/Powertel merger agreement was
fair, from a financial point of view, to such holders. After the presentation
and discussions, the Powertel board unanimously determined that each of the
Deutsche Telekom/Powertel merger and the VoiceStream/Powertel merger was fair
to, and in the best interests of, Powertel and Powertel stockholders, and
unanimously determined to approve each of the mergers and each of the merger
agreements and related agreements and to recommend that the Powertel
stockholders vote for the approval of each of the mergers and the merger
agreements.

     Following the approval of the Powertel board, each of the merger agreements
and all related agreements were executed on August 26, 2000.

     On Sunday, August 27, 2000, prior to the commencement of trading on the
Frankfurt Stock Exchange on August 28, 2000, an announcement was made regarding
the proposed mergers.

DEUTSCHE TELEKOM'S REASONS FOR THE DEUTSCHE TELEKOM/POWERTEL MERGER

     Deutsche Telekom believes that the Deutsche Telekom/Powertel merger will
complement the Deutsche Telekom/VoiceStream merger by augmenting Deutsche
Telekom's entry into the high-growth U.S. wireless telecommunications industry,
and will provide Powertel with the necessary capital resources,

                                       78
<PAGE>   97

technology expertise and national and global reach to provide cost-competitive
service and accelerate the introduction of next-generation voice and data
services to its customers. Deutsche Telekom believes that the Deutsche
Telekom/Powertel merger provides a unique opportunity to acquire a significant
number of potential customers and a wireless telecommunications network
utilizing the same GSM technology as Deutsche Telekom and VoiceStream.

VOICESTREAM'S REASONS FOR THE VOICESTREAM/POWERTEL MERGER

     VoiceStream believes that the addition of Powertel's wireless
communications business to VoiceStream's will make VoiceStream a more
competitive national wireless communications company with greater prospects for
growth than either VoiceStream or Powertel would have on its own and will
generate significant opportunities to deliver greater value to VoiceStream
stockholders (which would include former Powertel stockholders after the
VoiceStream/Powertel merger).

     Strong Geographic Fit.  VoiceStream is the only U.S. wireless
communications provider with a national network based on GSM wireless
technology. The addition of Powertel, which operates a GSM-based network in 12
southeastern states where VoiceStream generally does not operate, fills the most
significant gap in VoiceStream's U.S. coverage, and will give the combined
company more complete nationwide coverage. Together with Powertel and its
affiliates, VoiceStream will have licenses to serve 24 of the 25 largest markets
in the United States and have approximately 250 million licensed POPs.
Powertel's current network coverage enables access to approximately ____ million
potential customers and by 2001 this figure is expected to increase to ____
million customers. Access to these customers will strengthen VoiceStream's
ability to compete on a nationwide basis.

     Strong Technology Fit.  VoiceStream and Powertel operate compatible network
platforms utilizing GSM technology. By combining these networks, the combined
company will be a national wireless operator utilizing the GSM standard, capable
of offering its customers next-generation wireless voice and data services such
as wireless Internet and multimedia applications. Together, VoiceStream and
Powertel will offer seamless services over a common technology platform and
provide customer-friendly features such as global roaming, unified billing and
national customer service. VoiceStream believes that these services, which are
not currently offered in this form by any other U.S. providers will give
VoiceStream a competitive edge in the U.S. wireless communications industry.

RECOMMENDATION AND CONSIDERATIONS OF THE VOICESTREAM BOARD OF DIRECTORS WITH
RESPECT TO THE VOICESTREAM/POWERTEL MERGER

     On August 24, 2000, the board of directors of VoiceStream, by a unanimous
vote, determined the VoiceStream/Powertel merger and the other transactions
contemplated by the VoiceStream/Powertel merger agreement to be advisable, fair
to and in the best interests of VoiceStream and its stockholders, and approved
and adopted the VoiceStream/Powertel merger agreement. ACCORDINGLY, THE
VOICESTREAM BOARD RECOMMENDS THAT STOCKHOLDERS OF VOICESTREAM VOTE "FOR"
APPROVAL OF THE VOICESTREAM/POWERTEL MERGER AGREEMENT AT THE VOICESTREAM SPECIAL
MEETING.

     In the course of reaching its decision to adopt the VoiceStream/Powertel
merger agreement, the VoiceStream board consulted with management, as well as
with its outside legal counsel and financial advisors, and considered the
matters referred to above under "--VoiceStream's Reasons for the
VoiceStream/Powertel Merger," as well as the following material factors:

     - Complementary Strategies and Technologies; Opportunities for Growth. The
       VoiceStream board believed that there is a strong strategic and
       technology fit between VoiceStream's and Powertel's mobile communications
       businesses and operations, as described more fully above under
       "--VoiceStream's Reasons for the VoiceStream/Powertel Merger." In
       particular, the VoiceStream board noted that:

          -- In light of current conditions and trends in the telecommunications
             industry, including acquisitions that have increased the size and
             strength of VoiceStream's competitors, the

                                       79
<PAGE>   98

          VoiceStream board believed that in order to compete effectively,
          VoiceStream would need to continue to expand its geographic coverage
          and aggressively seek to grow its subscriber base;

          -- Powertel provides wireless telecommunications services in 12 states
             in the southeastern United States where VoiceStream generally does
             not operate. These states contain a population of approximately 25
             million people;

          -- Adding Powertel's network to VoiceStream's would give VoiceStream
             more complete nationwide coverage, with licenses to serve 24 of the
             25 largest markets in the United States;

          -- VoiceStream's and Powertel's mobile communications services are
             based on compatible network platforms using GSM wireless
             technology; and

          -- Because VoiceStream's and Powertel's networks are based on the same
             GSM standard, the combined company will be able to offer seamless
             services on a nationwide basis over a common technology platform
             and to provide services such as nationwide roaming, unified billing
             and nationwide customer service.

     The VoiceStream board observed that these compatibilities could enable the
     combined company to grow more quickly and beyond the levels VoiceStream
     could be expected to achieve without the VoiceStream/Powertel merger.

     - Financial Impact.  The VoiceStream board reviewed the historical
       operating results of VoiceStream and Powertel and the projected operating
       results of VoiceStream and Powertel individually and in combination and
       determined, among other things, that the VoiceStream/Powertel merger
       could be expected to have a positive effect on the combined company's
       balance sheet, earnings and cash flow.

     - Transaction Terms.  The VoiceStream board determined that terms of the
       VoiceStream/Powertel merger agreement, including the financial terms,
       were reasonable and appropriate, and that the relatively limited number
       of conditions and termination rights increased the likelihood that the
       transaction would be completed if the Deutsche Telekom/VoiceStream merger
       agreement is terminated.

     - Opinion of Financial Advisor.  Goldman Sachs, VoiceStream's financial
       advisor, made presentations to the VoiceStream board concerning financial
       aspects of the proposed VoiceStream/Powertel merger, and delivered its
       oral opinion, later confirmed in writing, that as of the date of that
       opinion, the conversion number under the VoiceStream/Powertel merger
       agreement was fair from a financial point of view to VoiceStream.

     - Powertel Stockholder Agreements.  Powertel is required to submit the
       VoiceStream/Powertel merger agreement to Powertel stockholders even if
       the Powertel board withdraws its recommendation, and holders of
       Powertel's common and preferred shares with sufficient voting power to
       approve the VoiceStream/Powertel merger have entered into stockholder
       agreements with VoiceStream in which such holders have agreed to vote
       their shares in favor of the VoiceStream/Powertel merger at the Powertel
       special meeting. As a result, Powertel stockholder approval of the
       VoiceStream/Powertel merger is assured even if the Powertel board
       withdraws or changes its recommendation.

     The VoiceStream board also considered the following potentially negative
factors associated with the VoiceStream/Powertel merger:

     - the risks described under "Risk Factors Relating to the
       VoiceStream/Powertel Merger;"

     - that because VoiceStream stockholders who, in the aggregate, had
       sufficient voting power as of the VoiceStream record date to approve the
       VoiceStream/Powertel merger have entered into stockholder agreements with
       Powertel and have agreed to vote all of their shares in favor of the
       VoiceStream/Powertel merger agreement. Accordingly, VoiceStream
       stockholder approval of the VoiceStream/Powertel merger is assured;
                                       80
<PAGE>   99

     - the risk that anticipated operating synergies and compatibilities may not
       be realized;

     - that the combined company following the VoiceStream/Powertel merger will
       still be significantly smaller than many of its major competitors and, as
       a result, the combined company will be required to raise significant
       amounts of capital in order to continue to grow, expand and build out its
       GSM network; and

     - the risk that a regulatory body could delay the VoiceStream/Powertel
       merger or impose conditions which reduce the anticipated benefits of the
       VoiceStream/Powertel merger.

     The VoiceStream board believed and continues to believe that these
potential risks are greatly outweighed by the anticipated benefits from the
VoiceStream/Powertel merger.

     The foregoing discussion addresses the material information and factors
considered by the VoiceStream board in its consideration of the
VoiceStream/Powertel merger, including factors that support the
VoiceStream/Powertel merger as well as those that may weigh against it. The
VoiceStream board conducted numerous discussions of the factors described above,
including asking questions of VoiceStream's management and legal and financial
advisors. In view of the variety of factors and the amount of information
considered, the VoiceStream board did not find it practicable to, and did not,
make specific assessments of, quantify or otherwise assign relative weights to
the specific factors considered in reaching its determination. In addition, the
VoiceStream board did not undertake to make any specific determination as to
whether any particular factor, or any aspect of any particular factor, was
favorable or unfavorable to its ultimate determination. The determination to
approve the VoiceStream/Powertel merger was made after consideration of all of
the factors as a whole. In addition, individual members of the VoiceStream board
may have given different weights to different factors.

RECOMMENDATION AND CONSIDERATIONS OF THE POWERTEL BOARD OF DIRECTORS WITH
RESPECT TO THE DEUTSCHE TELEKOM/POWERTEL MERGER AND VOICESTREAM/POWERTEL MERGER

     On August 26, 2000, at a special meeting, the Powertel board of directors
unanimously determined that each of the Deutsche Telekom/Powertel merger and the
VoiceStream/Powertel merger and the other transactions contemplated by each of
the Deutsche Telekom/Powertel merger agreement and the VoiceStream/Powertel
merger agreement, respectively, is advisable and in the best interests of
Powertel and its stockholders and approved and adopted each of the Deutsche
Telekom/Powertel merger agreement and the VoiceStream/Powertel merger agreement.
Accordingly, the Powertel board of directors recommends that Powertel
stockholders vote "FOR" approval of each of the mergers and the merger
agreements at the Powertel special meeting.

     In the course of reaching its decision to adopt each of the merger
agreements, the Powertel board of directors consulted with members of Powertel's
management as well as with Powertel's legal counsel and financial advisors, and
considered the following material factors, in addition to those set forth under
"-- Deutsche Telekom's Reasons for the Deutsche Telekom/Powertel Merger:"

     - the view of the Powertel board of directors and Powertel's management
       that in light of current conditions and trends in the telecommunications
       industry, including consolidation that has increased the size and
       strength of our competitors, (1) it is uncertain how regional operators,
       such as Powertel, will compete on a national or global basis and (2)
       Powertel's business and financial performance should benefit from being
       part of a larger, more diverse company;

     - an analysis of the potential stockholder value that could be expected to
       be generated from the various strategic alternatives available to
       Powertel, including the alternatives of (1) continuing as an independent
       company, (2) pursuing a series of acquisitions by Powertel to increase
       the size of Powertel's coverage area and (3) entering into a strategic
       business combination with another wireless telecommunications company;

     - the fact that (1) the Powertel board of directors and Powertel's
       management had investigated and discussed various strategic alternatives
       over a period of months, (2) there had been ongoing

                                       81
<PAGE>   100

       publicity and speculation in the market regarding Powertel possibly being
       a takeover target, (3) Morgan Stanley, at Powertel's direction, had
       contacted and solicited indications of interest from telecommunications
       companies that were viewed as potentially having an interest in engaging
       in a transaction with Powertel and (4) VoiceStream and Deutsche Telekom
       submitted the only firm proposal as a result of this process;

     - the view of Powertel's management and the Powertel board of directors
       that a merger of Powertel and VoiceStream, even if VoiceStream were not
       to combine with Deutsche Telekom, would represent an excellent "fit" from
       a strategic standpoint due to the companies' common GSM technology
       platform, non-overlapping coverage areas and consistent strategies that
       the companies were pursuing, and should produce a stronger combined
       company with increased economies of scale;

     - the fact that both transactions, because they are structured as
       stock-for-stock mergers, instead of as sales for cash, provide Powertel's
       stockholders with the opportunity to continue as stockholders in a
       larger, more competitive company;

     - the view of the Powertel board and Powertel's management as to the
       business, operations, properties and assets, financial condition,
       competitive position, business strategy and prospects of each of Deutsche
       Telekom and VoiceStream as well as the risks involved in achieving these
       prospects, and the economic and market conditions applicable to the
       telecommunications industry, both on a historical and on a prospective
       basis;

     - the fact that (1) Deutsche Telekom has significant financial resources,
       (2) regardless of whether the Deutsche Telekom/VoiceStream merger closes,
       Deutsche Telekom will invest $5 billion in VoiceStream and (3)
       VoiceStream is expected to use these funds for the continued build out
       and expansion of the GSM network in the United States;

     - the fact that the Deutsche Telekom/Powertel merger will not close unless
       the Deutsche Telekom/ VoiceStream merger closes, which necessarily means
       that, in either circumstance, Powertel will be combining its wireless
       coverage areas with VoiceStream's complementary wireless coverage areas
       to create a nationwide GSM-based wireless provider;

     - the fact that additional spectrum for wireless communications is expected
       to shortly become available, and this spectrum could be acquired by
       Deutsche Telekom, VoiceStream or other persons as an alternative to
       acquiring Powertel;

     - the expectation that each of the Deutsche Telekom/Powertel merger and the
       VoiceStream/Powertel merger will qualify as a tax-free transaction for
       U.S. federal income tax purposes (except with respect to cash received
       for fractional shares);

     - a review of the provisions contained in the draft Deutsche
       Telekom/Powertel and VoiceStream/Powertel merger agreements and related
       documents, including the various stockholders agreements in which
       Powertel stockholders holding a majority of the voting power entitled to
       vote with respect to the Deutsche Telekom/Powertel and
       VoiceStream/Powertel mergers were to agree to vote to approve those
       mergers; and

     - the presentations of Morgan Stanley, Powertel's financial advisors,
       concerning the financial aspects of the proposed mergers and of the
       various strategic alternatives available to Powertel, and the oral
       opinion received from Morgan Stanley, later confirmed in writing, that,
       as of the date of the opinion, and based on the considerations in the
       opinion, the consideration to be received by holders of Powertel common
       and preferred shares pursuant to the Deutsche Telekom/Powertel merger
       agreement was fair from a financial point of view to such holders, and,
       in the event the Deutsche Telekom/Powertel merger is not completed, the
       consideration to be received by holders of Powertel common and preferred
       shares pursuant to the VoiceStream/Powertel merger agreement was fair
       from a financial point of view to such holders.

                                       82
<PAGE>   101

     The Powertel board also considered the following potentially negative
factors associated with the mergers:

     - the fact that Deutsche Telekom ADSs, Deutsche Telekom ordinary shares and
       VoiceStream common shares have experienced substantial price volatility
       in recent months;

     - the fact that because the exchange ratios for Powertel shares in the
       Deutsche Telekom/Powertel merger are fixed, and because the provisions of
       the VoiceStream/Powertel merger agreement provide only limited price
       protection to Powertel stockholders, the value of the merger
       consideration to Powertel stockholders may decrease prior to the
       completion of the Deutsche Telekom/Powertel merger or the
       VoiceStream/Powertel merger, as the case may be;

     - with respect to the Deutsche Telekom/Powertel merger only that the market
       price for Deutsche Telekom shares to be received by Powertel stockholders
       in the Deutsche Telekom/Powertel merger may be adversely affected by the
       prospect of future sales of Deutsche Telekom shares by the Federal
       Republic of Germany and KfW, Deutsche Telekom's two largest shareholders,
       or by current Powertel stockholders who are not permitted to hold equity
       securities of non-U.S. companies or who otherwise elect not to hold
       Deutsche Telekom shares in their portfolios;

     - the fact that the Deutsche Telekom/VoiceStream merger and the Deutsche
       Telekom/Powertel merger may face enhanced regulatory scrutiny; and

     - the fact that the termination fee provisions of the Deutsche
       Telekom/Powertel merger agreement and the VoiceStream/Powertel merger
       agreement, together with the fact that Powertel stockholders that
       beneficially own greater than 50% of the Powertel shares entitled to vote
       on each of the Deutsche Telekom/Powertel merger and the
       VoiceStream/Powertel merger have agreed to vote in favor of each of the
       mergers, would likely discourage alternative proposals being made to
       Powertel (in this regard the Powertel board considered that the
       termination fee provisions of each of the Deutsche Telekom/Powertel
       merger agreement and the VoiceStream/Powertel merger agreement are
       customary for transactions of this type, and that these provisions, in
       addition to the Powertel stockholder agreements, were necessary to induce
       each of Deutsche Telekom and VoiceStream to enter into the transactions).

     The Powertel board believed that these potential risks were outweighed by
the potential benefits anticipated to result from the mergers. In considering
the proposed Deutsche Telekom/Powertel merger and the VoiceStream/Powertel
merger, the directors of Powertel were aware of the interests of certain
officers and directors of Powertel in the Deutsche Telekom/Powertel merger and
the VoiceStream/Powertel merger described below under "-- Interests of Directors
and Officers of Powertel in the Deutsche Telekom/Powertel Merger and the
VoiceStream/Powertel Merger."

     The foregoing discussion addresses the material information and factors
considered by the Powertel board in its consideration of the Deutsche
Telekom/Powertel merger and the VoiceStream/Powertel merger, including factors
that support each of the mergers as well as those that may weigh against each of
the mergers. The Powertel board of directors conducted numerous discussions of
the factors described above, including asking questions of Powertel's management
and legal and financial advisors. In view of the variety of factors and the
amount of information considered, the Powertel board of directors did not find
it practical to, and did not, make specific assessments of, quantify or
otherwise assign relative weights to the specific factors considered in reaching
its determination. In addition, the Powertel board of directors did not
undertake to make any specific determination as to whether any particular
factor, or any aspect of any particular factor, was favorable or unfavorable to
its ultimate determination. The determination to approve each of the Deutsche
Telekom/Powertel merger and the VoiceStream/Powertel merger was made after
consideration of all of the factors as a whole. In addition, individual members
of the Powertel board of directors may have given different weights to different
factors.

OPINION OF VOICESTREAM'S FINANCIAL ADVISOR

     Goldman Sachs has acted as financial advisor to VoiceStream in connection
with the proposed VoiceStream/Powertel merger. On August 24, 2000, Goldman Sachs
delivered its oral opinion to the VoiceStream board, conditioned on the
finalization of the VoiceStream/Powertel merger agreement in substantially the
form reviewed by Goldman Sachs on August 24, 2000. After VoiceStream and
Powertel finalized the VoiceStream/Powertel merger agreement, Goldman Sachs
confirmed its oral opinion in writing without such condition that, as of August
26, 2000, the conversion number under the VoiceStream/Powertel merger agreement
was fair from a financial point of view to VoiceStream. Goldman Sachs noted that
the VoiceStream/Powertel merger agreement would automatically terminate
concurrently with the closing of the Deutsche Telekom/VoiceStream merger, in
which event the VoiceStream/Powertel merger would not occur. In connection with
delivering its opinion for the VoiceStream/Powertel merger, Goldman Sachs did
not express any opinion with respect to the Deutsche Telekom/Powertel merger
agreement, the Deutsche Telekom/Powertel merger, the Deutsche
Telekom/VoiceStream merger agreement or the Deutsche Telekom/VoiceStream merger.

     The "conversion number" means (1) 0.75 if the VoiceStream average closing
price is $113.33 or below; (2) 0.65 if the VoiceStream average closing price is
$130.77 or above; and (3) if the VoiceStream average closing price is greater
than $113.33 and less than $130.77, the quotient determined by dividing $85.00
by the VoiceStream average closing price, in each case subject to reduction in
the event that the aggregate number of outstanding Powertel common shares and
securities convertible into or exchangeable for Powertel common shares as
calculated pursuant to the VoiceStream/Powertel merger agreement exceeds a
specified amount. The "VoiceStream average closing price" means the volume
weighted average closing price, based on the Nasdaq composite volume published
by the Wall Street Journal, of the VoiceStream common shares as publicly
reported on the Nasdaq Stock Market as of 4:00 p.m. eastern time for 10 trading
days randomly selected by lot within the last 20 trading days ending five
trading days prior to the closing date of the VoiceStream/Powertel merger.

     The full text of the Goldman Sachs opinion is attached as Annex E to this
proxy statement/ prospectus, and stockholders of VoiceStream are urged to, and
should, read such opinion in its entirety.

     In connection with its opinion, Goldman Sachs reviewed, among other things:

     - the VoiceStream/Powertel merger agreement, the Deutsche Telekom/Powertel
       merger agreement and the Deutsche Telekom/VoiceStream merger agreement;

     - the annual reports to stockholders and annual reports on Form 10-K of
       VoiceStream and VoiceStream predecessors and Powertel for the four years
       ended December 31, 1999;

     - the definitive proxy statement dated January 25, 2000 in connection with
       the acquisitions by VoiceStream of Aerial and Omnipoint;

     - certain interim reports to stockholders and quarterly reports on Form
       10-Q of VoiceStream and Powertel;

     - other communications from VoiceStream and Powertel to their respective
       stockholders;

     - internal financial analyses and forecasts for Powertel prepared by
       management of Powertel;

     - internal financial analyses and forecasts for VoiceStream prepared by
       management of VoiceStream; and

     - internal financial analyses and forecasts for Powertel prepared by the
       management of VoiceStream.

     Goldman Sachs also held discussions with members of the senior management
of VoiceStream and Powertel regarding their assessment of the strategic
rationale for, and the potential benefits of, the transaction contemplated by
the VoiceStream/Powertel merger agreement and the past and current

                                       84
<PAGE>   103

business operations, financial condition and future prospects of their
respective companies. In addition, Goldman Sachs:

     - reviewed the reported price and trading activity for the VoiceStream
       common shares and the Powertel common shares;

     - compared certain financial and stock market information for VoiceStream
       and Powertel with similar information for certain other companies the
       securities of which are publicly traded;

     - reviewed the financial terms of certain recent business combinations in
       the telecommunications industry specifically and in other industries
       generally; and

     - performed such other studies and analyses as Goldman Sachs considered
       appropriate.

     Goldman Sachs relied upon the accuracy and completeness of all of the
financial and other information discussed with or reviewed by it and assumed
such accuracy and completeness for purposes of rendering its opinion.
Specifically, Goldman Sachs assumed with the consent of the VoiceStream board
that the internal financial forecasts for Powertel prepared by VoiceStream
management have been reasonably prepared on a basis reflecting the best
currently available estimates and judgments of VoiceStream, and that those
forecasts will be realized in the amounts and time periods contemplated thereby.
In addition, Goldman Sachs did not make an independent evaluation or appraisal
of the assets and liabilities of VoiceStream or Powertel or any of their
subsidiaries and Goldman Sachs was not furnished with any such evaluation or
appraisal. Goldman Sachs also assumed that all material governmental, regulatory
or other consents and approvals necessary for the completion of the transaction
will be obtained without any adverse effect on VoiceStream or Powertel or on the
expected benefits of the VoiceStream/Powertel merger. Goldman Sachs's advisory
services and opinion were provided for the information and assistance of the
VoiceStream board in connection with its consideration of the transaction
contemplated by the VoiceStream/Powertel merger agreement and the opinion does
not constitute a recommendation as to how any holder of VoiceStream common
shares should vote with respect to the VoiceStream/Powertel merger agreement or
merger.

     The following is a summary of the material financial analyses presented by
Goldman Sachs to the VoiceStream board on August 24, 2000. Some of the summaries
of the financial analyses include information presented in tabular format. The
tables must be read together with the text accompanying each summary.

     Contribution Analysis

     Goldman Sachs performed an analysis the purpose of which was to determine
how the contribution of Powertel to the combined company, based on the various
measurement factors described below, compared to the percentage of the total
equity of the combined company that Powertel stockholders would receive as a
result of the VoiceStream/Powertel merger. Goldman Sachs noted that, based on
the range of potential conversion numbers of 0.65-.075, the Powertel
stockholders would receive between 10.7% and 12.2% of the total equity of the
combined company pursuant to the VoiceStream/Powertel merger agreement. In
preparing this analysis, Goldman Sachs reviewed certain estimated future
operating and financial information for VoiceStream and Powertel supplied to
Goldman Sachs by VoiceStream management. The measurement factors that Goldman
Sachs considered included for each of 2000, 2001 and 2002:

     - covered POPs;

     - subscribers;

     - service revenues;

     - EBITDA;

     - equity value; and

     - enterprise value.

                                       85
<PAGE>   104

     The projected financial information for each of VoiceStream and Powertel
was provided by the VoiceStream management. As projected:

     - "POPs" are the number of persons within a license's coverage area and are
       derived from management estimates and public sources.

     - "Covered POPs" are the estimated number of POPs within the license area
       served by the operating network.

     - "Subscribers" is an estimated number of enrolled customers in a company's
       subscription plans.

     - "Service revenues" are the estimated revenues derived from providing
       communications services.

     - "EBITDA" stands for earnings before interest, taxes, depreciation and
       amortization.

     - "Equity value" represents each company's enterprise value net of the book
       value of its outstanding net indebtedness and estimated non-core assets.

     - "Enterprise value" is the sum of a company's market capitalization, total
       debt, preferred shares and minority interest, less cash and cash
       equivalents.

     The following table presents the results of that analysis:

     Discounted Cash Flow Analysis

     Goldman Sachs performed an analysis the purpose of which was to compare the
present value per share of Powertel, using discounted cash flow methodologies,
to the present value per share of VoiceStream. Goldman Sachs performed this
analysis by determining ranges of enterprise values and equity values for
Powertel and VoiceStream, each on a stand-alone basis without accounting for any
synergies. Specifically, Goldman Sachs considered the range of values for
Powertel and VoiceStream, each on a stand-alone basis, based in both cases on
VoiceStream management's internal model for each company. The following table
presents the ranges of enterprise values and equity values, as well as the price
per share and the ratio of enterprise value to 2001 Covered POPs for both
Powertel and VoiceStream, based on forward 2009 EBITDA multiples for Powertel
and VoiceStream ranging from 9.0x to 13.0x and discount rates ranging from 11%
to 15%.

     Transaction Premium Analysis

     Goldman Sachs performed an analysis the purpose of which was to assess the
premiums represented by assumed conversion numbers over the conversion number
that would be implied by the price or average prices of VoiceStream common
shares and Powertel common shares at a point in time or over a period of time.
The assumed conversion numbers used were 0.65 and 0.75, the minimum and maximum
possible conversion numbers under the VoiceStream/Powertel merger agreement, and
0.70, the median of those two. The point in time and periods used in the
analysis were August 18, 2000 and the 10-day, 20-day, 30-day, 60-day,
three-month, six-month, nine-month and one-year periods ending August 18, 2000,
the last trading day before any public reports of the proposed Deutsche

     Selected Companies Analysis

     Goldman Sachs performed an analysis the purpose of which was to determine
how different measures of the price per POP for Powertel, VoiceStream and the
combined VoiceStream/Powertel compared to the same measures of price per POP for
the following selected companies: TeleCorp PCS Inc., Sprint PCS Group, Triton
PCS Holdings Inc. and Nextel Communications Inc. The price per POP in each case
was calculated by dividing the respective company's core enterprise value or
adjusted enterprise value by different measures of that company's POPs. In this
analysis:

     - "Core enterprise value" for each of the companies is the sum of its
       market capitalization, total debt, preferred shares and minority
       interest, less cash, cash equivalents and an estimate of non-core assets.

     - "Adjusted enterprise value" for each of the companies is the core
       enterprise value for that company less the value of unbuilt POPs, valued
       at $25.00 per POP.

                                       87
<PAGE>   106

     - "Weighted Total POPs" are determined by multiplying the number of POPs in
       a 30 MHz license area by one, the number of POPs in a 20 MHz license area
       by 0.75, the number of POPs in a 10 MHz license area by 0.25 and, with
       respect to Nextel, the number of Nextel POPs by 0.75, and reflect the
       fact that licenses with greater MHz provide greater bandwith or capacity.

     The analysis was performed using share prices as of August 18, 2000.
Finally, "2001 Covered POP Value" represents adjusted enterprise value divided
by projected 2001 Covered POPs, "Weighted Total POP Value" represents core
enterprise value divided by Weighted Total POPs and "Total POP Value" represents
core enterprise value divided by total, unadjusted POPs.

     The following chart summarizes the results of that analysis:

     Pro Forma Merger Analysis

     Goldman Sachs also analyzed the potential effects of the
VoiceStream/Powertel merger on VoiceStream's projected EBITDA per share for
2000, 2001 and 2002. Goldman Sachs conducted the analysis using assumed
conversion numbers of 0.65 and 0.75, the minimum and maximum possible conversion
numbers under the VoiceStream/Powertel merger agreement, as well as an assumed
$85.00 per share value for Powertel common shares. The analysis also used
estimates for VoiceStream and Powertel EBITDA for 2000, 2001 and 2002 provided
by VoiceStream management. The following table presents the results of this

     The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description. Selecting
portions of the analysis or of the summary set forth above, without considering
the analyses as a whole, could create an incomplete view of the processes
underlying Goldman Sachs's opinion. In arriving at its fairness determination,
Goldman Sachs considered the results of all such analyses. No company or
transaction used in the above analyses as a comparison is directly comparable to
VoiceStream or Powertel or the merger. Goldman Sachs prepared the analyses
solely for purposes of providing its opinion to the VoiceStream board as to the
fairness of the conversion number. The analyses do not purport to be appraisals
or necessarily reflect the prices at which the business or securities actually
may be sold. Analyses based upon forecasts of future results, which are
inherently subject to uncertainty, are not necessarily indicative of actual
future results, which may be significantly more or less favorable than suggested
by such analyses.

engaged in the valuation of businesses and their securities in connection with
mergers and acquisitions, negotiated underwritings, competitive biddings,
secondary distributions of listed and unlisted securities, private placements
and valuations for estate, corporate and other purposes. VoiceStream selected
Goldman Sachs as its financial advisor because it is a nationally recognized
investment banking firm that has substantial experience in transactions similar
to the merger and because of Goldman Sachs' familiarity with VoiceStream arising
from having provided investment banking services in the past to VoiceStream and
its predecessor.

     Goldman Sachs is familiar with VoiceStream having provided certain
investment banking services to (1) VoiceStream, (2) VoiceStream's predecessor,
VoiceStream Wireless Corporation, a Washington corporation, referred to in this
description as VoiceStream Washington, and (3) VoiceStream Washington's former

       amount of 10.5% senior subordinated notes due February 2007 of Western
       Wireless in October 1996;

     - Western Wireless's financial advisor in connection with the sale of 19.9%
       of the outstanding shares of VoiceStream Washington's common shares to
       Hutchison PCS (USA) Limited in February 1998;

     - lead manager in the public offering of 13.915 million Western Wireless
       common shares in April 1998;

       Omnipoint in June 1999;

     - VoiceStream's financial advisor in connection with the acquisition of
       Aerial in September 1999;

     - lead manager in the private offering of $1.1 billion aggregate principal
       amount of 10% senior notes due November 2009 of VoiceStream Washington
       and VoiceStream and $720 million aggregate principal amount of 11% senior
       discount notes due November 2009 of VoiceStream Washington and
       VoiceStream in November 1999;

     - VoiceStream's financial advisor in connection with, and having
       participated in certain of the negotiations leading to, the Deutsche
       Telekom/VoiceStream merger agreement; and

     - VoiceStream's financial advisor in connection with, and having
       participated in certain of the negotiations leading to, the
       VoiceStream/Powertel merger agreement.

     As of August 26, 2000, investment funds affiliated with Goldman Sachs had a
principal investment in VoiceStream in the amount of 10,088,128 VoiceStream
common shares and have the right to designate a nominee for election to the
VoiceStream board of directors. Terrence O'Toole, a managing director of Goldman
Sachs, is a director of VoiceStream. Goldman Sachs has also provided investment
banking services to Powertel including having purchased from Ericsson, Inc. in
December 1998 $165 million aggregate principal amount of a tranche of the loan
made from Ericsson to Powertel, and in June 1998 an additional $100 million
aggregate principal amount of a tranche of that loan, and having acted as a
lender under, and having been a party to agreements with respect to, that loan.

     Goldman Sachs provides a full range of financial advisory and securities
services and, in the course of its normal trading activities, may from time to
time effect transactions and hold securities, including derivative securities,
of VoiceStream and Powertel for its own account and for the accounts of
customers. As of August 26, 2000, Goldman Sachs had accumulated a net long
position of 308 Powertel shares. As of the same date and not including the
principal investment referred to above, Goldman Sachs had a net short position
of 180,716 shares of VoiceStream common shares.

OPINION OF POWERTEL'S FINANCIAL ADVISOR

     Under an engagement letter, dated as of January 12, 2000, Powertel engaged
Morgan Stanley to provide financial advisory services to Powertel. The Powertel
board of directors selected Morgan Stanley to act as its financial advisor based
on Morgan Stanley's qualifications, expertise and reputation, as well as Morgan
Stanley's knowledge of the business and affairs of Powertel.

     On August 26, 2000, Morgan Stanley delivered its oral opinion, subsequently
confirmed in writing, to the Powertel board of directors that, as of such date,
and subject to and based upon the various considerations, assumptions,
limitations and qualifications set forth in its opinion (1) the consideration to
be received by holders of Powertel common shares and preferred shares pursuant
to the Deutsche Telekom/Powertel merger agreement is fair from a financial point
of view to holders of Powertel common shares and preferred shares and (2) in the
event the Deutsche Telekom/VoiceStream merger is not completed, the
consideration to be received by the holders of Powertel common shares and
preferred shares pursuant to the VoiceStream/Powertel merger agreement is fair
from a financial point of view to the holders of Powertel common shares and
preferred shares.

     The full text of Morgan Stanley's opinion, dated August 26, 2000, which
sets forth, among other things, assumptions made, procedures followed, matters
considered and limitations on the scope of the review undertaken by Morgan
Stanley in rendering its opinion, is attached to this proxy statement/
prospectus as Annex F. Powertel stockholders are urged to read the entire
opinion carefully and in its entirety.

     Morgan Stanley's opinion is directed to the Powertel board of directors and
only addresses the fairness of the consideration to be received by the holders
of Powertel common shares and preferred shares pursuant to the Deutsche
Telekom/Powertel merger agreement, and if the Deutsche Telekom/Powertel merger
is not completed, the fairness of the consideration to be received pursuant to
the VoiceStream/ Powertel merger agreement, in each case from a financial point
of view, as of the date of the opinion. Morgan Stanley's opinion does not
address any other aspect of the Deutsche Telekom/Powertel merger and the
VoiceStream/Powertel merger, and does not constitute a recommendation to any
Powertel stockholder as to how to vote at the Powertel special meeting. This
summary is qualified in its entirety by reference to the full text of the
opinion.

In connection with rendering its opinion, Morgan Stanley, among other things:

     - reviewed certain publicly available financial statements and other
       information of Powertel, Deutsche Telekom and VoiceStream;

     - reviewed certain internal financial statements and other financial and
       operating data concerning Powertel, Deutsche Telekom and VoiceStream
       prepared by the managements of Powertel, Deutsche Telekom, and
       VoiceStream, respectively;

     - analyzed certain financial projections prepared by the management of
       Powertel;

     - analyzed certain financial projections for Deutsche Telekom and
       VoiceStream contained in certain securities analysts' research reports
       that were recommended for review by the managements of Deutsche Telekom
       and VoiceStream, respectively;

     - discussed the past and current operations and financial condition and the
       prospects of Powertel, including information relating to certain
       strategic, financial and operational benefits anticipated from

                                       90
<PAGE>   109

       each of the Deutsche Telekom/Powertel merger and the VoiceStream/Powertel
       merger, with senior executives of Powertel;

     - discussed the past and current operations and financial condition and the
       prospects of Deutsche Telekom, including information relating to certain
       strategic, financial and operational benefits anticipated from the
       Deutsche Telekom/Powertel merger with senior executives of Deutsche
       Telekom;

     - discussed the past and current operations and financial condition and the
       prospects of VoiceStream, including information relating to certain
       strategic, financial and operational benefits anticipated from the
       VoiceStream/Powertel merger with senior executives of VoiceStream;

     - discussed the past and current operations and financial condition and the
       prospects of Deutsche Telekom and VoiceStream, including information
       relating to certain strategic, financial and operational benefits
       anticipated from the VoiceStream merger, with senior executives of
       Deutsche Telekom and VoiceStream;

     - reviewed the reported prices and trading activity for the Powertel common
       shares, the Deutsche Telekom ADSs and the VoiceStream common shares;

     - compared the financial performance of Powertel, Deutsche Telekom and
       VoiceStream and the prices and trading activity of the Powertel common
       shares, the Deutsche Telekom ADSs and the VoiceStream common shares with
       those of certain other publicly-traded companies comparable with
       Powertel, Deutsche Telekom and VoiceStream respectively and their
       securities;

     - reviewed the financial terms, to the extent publicly available, of
       certain comparable acquisition transactions;

     - participated in discussions and negotiations among representatives of
       Powertel, Deutsche Telekom and VoiceStream and their financial and legal
       advisors;

     - reviewed the terms, including the financial terms, of the Deutsche
       Telekom/Powertel merger agreement, the VoiceStream/Powertel merger
       agreement and the Deutsche Telekom/VoiceStream merger agreement and
       certain related documents; and

     - performed other analyses and considered other factors as we have deemed
       appropriate.

     For purposes of its opinion, Morgan Stanley analyzed the merger as if the
Powertel preferred shares were converted into Powertel common shares immediately
prior to the completion of the Deutsche Telekom/Powertel merger or the
VoiceStream/Powertel merger. Morgan Stanley's opinion does not extend to the
conversion terms of the Powertel preferred shares.

     In rendering its opinion, Morgan Stanley assumed and relied upon without
independent verification the accuracy and completeness of the information
reviewed by Morgan Stanley for the purposes of its opinion. With respect to the
financial projections, including information relating to certain strategic,
financial and operational benefits anticipated from each of the Deutsche
Telekom/Powertel merger, VoiceStream/Powertel merger and Deutsche
Telekom/VoiceStream merger, Morgan Stanley assumed they were reasonably prepared
on bases reflecting the best currently available estimates and judgments of the
future financial performance of Deutsche Telekom, VoiceStream and Powertel. For
the purpose of its analysis, Morgan Stanley relied with Powertel's consent on
the estimates of certain securities analysts' research reports that were
recommended for review by the managements of Deutsche Telekom and VoiceStream.

     Morgan Stanley also assumed that the VoiceStream/Powertel merger will be
completed only if the Deutsche Telekom/VoiceStream merger agreement is
terminated. In addition, Morgan Stanley assumed that the Deutsche
Telekom/Powertel merger will be completed in accordance with the terms set forth
in the Deutsche Telekom/Powertel merger agreement, including that the Deutsche
Telekom/Powertel merger will be treated as a tax-free merger and/or exchange
pursuant to the U.S. tax code, and Morgan Stanley assumed that in the event the
Deutsche Telekom/VoiceStream merger is terminated, the
                                       91

VoiceStream/Powertel merger will be completed in accordance with the terms set
forth in the VoiceStream/Powertel merger agreement, including that the
VoiceStream/Powertel merger will be treated as a tax-free merger and/or exchange
pursuant to the U.S. tax code. Morgan Stanley also assumed that obtaining all
necessary regulatory approvals for the Deutsche Telekom/Powertel merger or
VoiceStream/ Powertel merger will not have a material adverse effect on
Powertel, VoiceStream or Deutsche Telekom or the financial, strategic and
operational benefits anticipated from the Deutsche Telekom/Powertel merger, the
Deutsche Telekom/VoiceStream merger or the VoiceStream/Powertel merger. Morgan
Stanley did not make any independent valuation or appraisal of the assets or
liabilities of Powertel, Deutsche Telekom or VoiceStream nor was Morgan Stanley
furnished with any such appraisals. Morgan Stanley's opinion is necessarily
based on financial, economic, market and other conditions as in effect on, and
the information made available to it as of August 26, 2000.

     The following is a brief summary of the material financial analyses
performed by Morgan Stanley in connection with its oral opinion and the
preparation of its opinion letter dated August 26, 2000. These summaries of
financial analyses include information presented in tabular format. In order to
fully understand the financial analyses used by Morgan Stanley, the tables must
be read together with the text of each summary. The tables alone do not
constitute a complete description of the financial analyses.

     Historical Public Market Trading Value

     Morgan Stanley reviewed the recent price performance of Powertel common
shares based on an analysis of the historical closing prices and trading volumes
over the last twelve months ending August 25, 2000. The following table lists
the average daily closing prices of Powertel common shares for the periods
indicated. Morgan Stanley then compared the consideration to be received
pursuant to the Deutsche Telekom/Powertel merger and VoiceStream/Powertel merger
by holders of Powertel common shares on a per share basis of approximately
$106.24 and $85.00 respectively, based on the closing prices of the Deutsche
Telekom ADSs and VoiceStream common shares on August 25, 2000, to the average
Powertel closing prices over this period.

  Comparable Companies Analysis

     Using closing market prices on August 25, 2000, Morgan Stanley calculated
aggregate value, defined as equity value adjusted for capital structure, to
service revenue multiples for Powertel and VoiceStream for fiscal year 2001 and
subscriber multiples for Powertel and VoiceStream for fiscal year 2001 based on
publicly available research estimates compiled by Powertel's management, as
adjusted for certain operating assumptions reflected in publicly available
reports, and based on publicly available research estimates for VoiceStream.
Morgan Stanley then compared the service revenue and subscriber multiples
obtained for Powertel and VoiceStream with multiples obtained for selected
domestic companies that provide PCS

services, including Sprint PCS and Nextel Communications, Inc. ("Domestic PCS
Peer Group") based on publicly available research estimates. In addition, Morgan
Stanley calculated aggregate value to fiscal year 2001 revenue multiples and
aggregate value to EBITDA multiples for fiscal year 2001 for Deutsche Telekom
based on publicly available research estimates. Morgan Stanley then compared the
fiscal year 2001 revenue and EBITDA multiples for Deutsche Telekom with
multiples obtained for a group of selected peer companies based on publicly
available research estimates. The group of selected Deutsche Telekom peer
companies ("Deutsche Telekom Peer Group") included France Telecom S.A.,
Koninklijke KPN NV and Telecom Italia SpA. This analysis resulted in the
following information:

     Morgan Stanley noted that the consideration to be received by a holder of a
Powertel common share pursuant to the Deutsche Telekom/Powertel merger based on
the closing price of the Deutsche Telekom ADSs on August 25, 2000 represented a
multiple of $390 per Powertel's current covered POPs and 9.9x Powertel's fiscal
year 2001 service revenue. Furthermore, Morgan Stanley noted that the
consideration received pursuant to the VoiceStream/Powertel merger based on the
closing price of VoiceStream common shares on August 25, 2000 represented a
multiple of $320 per Powertel's current covered POPs and 8.1x Powertel's fiscal
year 2001 service revenue.

  Securities Research Analysts' Future Price Targets Analysis

     Morgan Stanley reviewed the 12-month price targets for Powertel common
shares as projected by analysts from various financial institutions in recent
reports. These targets reflected each analyst's estimate of the future public
market trading price of the Powertel common shares at the end of the particular
period considered for each estimate. Morgan Stanley then arrived at the present
value for these targets using an estimated equity discount rate of 15.0% for the
Powertel common shares.

     This analysis showed the following mean and median present values for the
Powertel common shares:

  Historical Exchange Ratio Analysis

     Morgan Stanley reviewed the implied historical exchange ratios for Powertel
common shares, Deutsche Telekom ADSs and VoiceStream common shares. These
exchange ratios were determined by dividing the price per Powertel common share
by the price per Deutsche Telekom ADS and the price per VoiceStream common share
over the one year period from August 25, 1999 through August 25, 2000. Morgan
Stanley performed this analysis to compare premia or discounts represented by
the consideration received pursuant to the Deutsche Telekom/Powertel merger and
the VoiceStream/Powertel merger with the premium or discount represented by
historical exchange ratios prevailing in the open market.

     This analysis indicated the following premia/(discounts) represented by the
average historical exchange ratios prevailing in the open market:

  Analysis of Selected Precedent Transactions

     Morgan Stanley reviewed the following three transactions involving domestic
PCS companies since June 1999:

     - June 1999 -- VoiceStream Wireless/Omnipoint

     - September 1999 -- VoiceStream Wireless/Aerial; and

     - July 2000 -- Deutsche Telekom/VoiceStream.

     For each of these transactions, Morgan Stanley reviewed and calculated the
consideration paid per current licensed POPs, per current covered POPs and per
current subscribers and calculated the consideration paid as a multiple of
estimated service revenues for the next one year. This analysis indicated the
following multiples for these transactions:

  Discounted Cash Flow Analysis

     Morgan Stanley performed a discounted cash flow analysis, which considers
the present value of projected cash flows using discount rates and terminal year
free cash flow perpetual growth rates, as

                                       94
<PAGE>   113

indicated below, of Powertel's business. Morgan Stanley analyzed Powertel's
business for the period beginning January 1, 2000 and ending December 31, 2009,
based on publicly available research estimates compiled by Powertel's
management, as adjusted for certain operating assumptions reflected in publicly
available reports. Morgan Stanley estimated Powertel's discounted cash flow
value by using a discount rate range of 12.0% to 12.5% and terminal year free
cash flow growth rates ranging from 5.0% to 5.5%. This analysis yielded a range
of values for the Powertel common shares of approximately $90 per share to $106
per share. Morgan Stanley noted that the consideration received pursuant to the
Deutsche Telekom/Powertel merger based on the closing price of the Deutsche
Telekom ADSs on August 25, 2000 represented a 0% to 18% premium to the Powertel
per share discounted cash flow value. Furthermore, Morgan Stanley noted that the
consideration received pursuant to the VoiceStream/Powertel merger based on the
closing price of the VoiceStream's common shares on August 25, 2000 represented
a 6% to 25% discount to the Powertel per share discounted cash flow value. In
addition, Morgan Stanley performed sensitivity analyses on assumptions
underlying Powertel's business forecast. Specifically, Morgan Stanley varied the
assumptions regarding the revenue growth and EBITDA margin in the terminal year.
Using a 12.0% discount rate and a 5.5% terminal year free cash flow growth rate,
Morgan Stanley arrived at values for the Powertel common shares ranging from
approximately $83 per share to $107 per share.

     Morgan Stanley performed a variety of financial and comparative analyses
solely for purposes of providing its opinion to the Powertel board of directors
as to the fairness from a financial point of view to the holders of Powertel
common shares and preferred shares of the consideration received in the Deutsche
Telekom/Powertel merger or VoiceStream/Powertel merger.

     The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description. In arriving
at its opinion, Morgan Stanley considered the results of all of its analyses as
a whole and did not attribute any particular weight to any analysis or factor
considered by it. Morgan Stanley believes that the summary provided and the
analyses described above must be considered as a whole and that selecting any
portion of its analyses, without considering all analyses, would create an
incomplete view of the process underlying its analyses and opinion. In addition,
Morgan Stanley may have given various analyses and factors more or less weight
than other analyses and factors, and may have deemed various assumptions more or
less probable than other assumptions, so that the ranges of valuations resulting
from any particular analysis described above should not be taken to be Morgan
Stanley's view of the actual value of Deutsche Telekom, VoiceStream or Powertel.

     No company used in the Comparable Company Analysis is identical to Deutsche
Telekom, VoiceStream or Powertel, and no transaction used in the Analysis of
Selected Precedent Transactions is identical to the Deutsche Telekom/Powertel
merger or the VoiceStream/Powertel merger. In performing its analyses, Morgan
Stanley made numerous judgments and assumptions with respect to industry
performance, general business, economic, market and financial conditions and
other matters, many of which are beyond the control of Deutsche Telekom,
VoiceStream or Powertel. In addition, mathematical analysis, such as determining
the average or the median, is not in itself a meaningful method of using
comparable company or precedent transaction data.

     The analyses performed by Morgan Stanley are not necessarily indicative of
future results or actual values, which may be significantly more or less
favorable than those suggested by such estimates. The analyses performed were
prepared solely as part of Morgan Stanley's analysis of the fairness of the
consideration received pursuant to the Deutsche Telekom/Powertel merger or
VoiceStream/Powertel merger from a financial point of view to the holders of
Powertel common shares and preferred shares and were conducted in connection
with the delivery of its opinion to the Powertel board of directors. Morgan
Stanley's analyses are not intended to be appraisals or to reflect the prices at
which Deutsche Telekom, VoiceStream or Powertel might actually be sold or the
price at which their securities may trade.

     The consideration received pursuant to the Deutsche Telekom/Powertel merger
or VoiceStream/ Powertel merger was determined through arm's length negotiations
between Powertel, Deutsche Telekom and VoiceStream and was approved by the
Powertel board of directors. Morgan Stanley did not recommend any specific
merger consideration to Powertel or that any specific merger consideration

                                       95
<PAGE>   114

constituted the only appropriate merger consideration for the Deutsche
Telekom/Powertel merger or VoiceStream/Powertel merger. Morgan Stanley's opinion
to the Powertel board was one of many factors taken into consideration by the
Powertel board of directors in making its determination to approve the Deutsche
Telekom/Powertel merger or VoiceStream/Powertel merger. Consequently, the Morgan
Stanley analyses described above should not be viewed as determinative of the
opinion of the Powertel board of directors with respect to the value of Powertel
or whether the Powertel board of directors would have been willing to agree to
different merger consideration.

     Morgan Stanley is an internationally recognized investment banking and
advisory firm. Morgan Stanley, as part of its investment banking business, is
continuously engaged in the valuation of businesses and securities in connection
with mergers and acquisitions, negotiated underwritings, competitive biddings,
secondary distributions of listed and unlisted securities, private placements
and valuations for corporate and other purposes. In the past, Morgan Stanley and
its affiliates have provided financial advisory and financing services for
Powertel and Deutsche Telekom and have received customary fees for the rendering
of these services. In the ordinary course of Morgan Stanley's business, Morgan
Stanley or its affiliates may at any time hold long or short positions, may
trade, make a market or otherwise effect transactions, for its own account, the
accounts of investment funds and other clients under the management of Morgan
Stanley or for the accounts of customers, in the securities or indebtedness of
Deutsche Telekom, VoiceStream and Powertel.

     Under the letter agreement dated as of January 12, 2000, Morgan Stanley has
provided advisory services and a financial opinion in connection with the
Deutsche Telekom/Powertel merger or VoiceStream/Powertel merger, and Powertel
has agreed to pay a fee to Morgan Stanley of $28 million if the Deutsche
Telekom/Powertel merger is consummated or a fee of $23 million if the
VoiceStream/ Powertel merger is consumated. In addition, Powertel has also
agreed to reimburse Morgan Stanley for its expenses incurred in performing its
services and to indemnify Morgan Stanley and its affiliates, their respective
directors, officers, agents and employees and each person, if any, controlling
Morgan Stanley or any of its affiliates against certain liabilities and
expenses, including the fees of its legal counsel and certain liabilities under
the federal securities laws, related to or arising out of Morgan Stanley's
engagement and any related transactions.

INTERESTS OF DIRECTORS AND OFFICERS OF VOICESTREAM IN THE VOICESTREAM/POWERTEL
MERGER

     Sonera Corporation is a significant stockholder of both VoiceStream and
Powertel, beneficially owning approximately 8.3% and 12.8% of their common
shares outstanding, respectively. Under the VoiceStream voting agreement, Sonera
has designated one representative to the VoiceStream board of directors. Sonera
also has the right to designate one representative to the Powertel board of
directors, but is not currently exercising such right, although a Sonera
representative currently attends meetings of the Powertel board of directors as
an observer.

INTERESTS OF DIRECTORS AND OFFICERS OF POWERTEL IN THE DEUTSCHE TELEKOM/POWERTEL
MERGER AND THE VOICESTREAM/POWERTEL MERGER

     Some of the directors and officers of Powertel have interests in the
Deutsche Telekom/Powertel merger and the VoiceStream/Powertel merger that are
different from, or in addition to, the interests of Powertel stockholders
generally. These interests, to the extent material, are described below. The
Powertel board of directors was aware of these interests and considered them,
among other matters, in approving both the Deutsche Telekom/Powertel merger
agreement and the Deutsche Telekom/Powertel merger and the VoiceStream/Powertel
merger agreement and the VoiceStream/Powertel merger.

  Treatment of Equity Awards

     Each merger agreement provides that, immediately prior to the completion of
the Deutsche Telekom/ Powertel merger and the VoiceStream/Powertel merger each
outstanding option to purchase Powertel common shares will be converted into the
right to acquire Deutsche Telekom ordinary shares or

                                       96

Agreement -- Treatment of Powertel Options and Restricted Stock." Except as
provided below, none of the options to purchase Powertel common shares will be
subject to accelerated vesting. In the event an employee's employment is
terminated by Deutsche Telekom or VoiceStream, as the case may be, because of
job elimination resulting from the Deutsche Telekom/Powertel merger or the
VoiceStream/Powertel merger within 18 months of the closing of the applicable
merger, then the employee's options may become fully vested and exercisable,
subject to certain limitations and restrictions. In addition to actual job loss,
an employee's employment will be considered to have been terminated by Deutsche
Telekom or VoiceStream, as the case may be, because of work elimination if (1)
that employee's employment with the surviving corporation terminates within 30
days after the employee is subjected to a reduction in the employee's salary,
hourly wage or target bonus or (2) if the employee is required to transfer to a
workplace 50 miles or more from their current job location. Any employee who
receives accelerated vesting of his or her options will not be entitled to any
actual or potential remaining payments under the cash bonus, retention bonus or
incentive bonus plans that are described below. However, individuals who are
eligible to receive payments under the severance plan will still be able to
receive those payments, except that those payments will be reduced by any
amounts that were previously paid to the employee under the cash bonus, the
retention bonus or the incentive bonus plans. To obtain accelerated vesting, an
employee will be required to sign and deliver to the surviving corporation a
full release of all claims against Powertel, Deutsche Telekom, VoiceStream and
all related parties. In addition, all restrictions on outstanding restricted
shares held by Powertel employees will lapse upon the closing of the Deutsche
Telekom/Powertel merger or VoiceStream/Powertel merger, as the case may be.

     Powertel will be allowed to issue an aggregate of 575,000 options prior to
the completion of the Deutsche Telekom/Powertel merger to Powertel employees in
yearly performance grants, to DiGiPH employees that become Powertel employees
and in connection with offers of employment outstanding as of August 26, 2000.
Employees whose employment is terminated due to job elimination resulting from
the merger will receive change of control accelerated vesting of their options
if their job is eliminated with eighteen months of the completion of the
Deutsche Telekom/Powertel merger. Individuals receiving change of control
vesting will not be eligible for payments under the cash bonus, retention bonus
or incentive bonus plans but will be eligible for severance payments, subject to
certain reductions.

  Cash and Retention Bonus Plans

     Pursuant to the Deutsche Telekom/Powertel and the VoiceStream/Powertel
merger agreements, cash and retention bonus plans will be established for
Powertel management employees, including the executive officers of Powertel.
Pursuant to the cash bonus plan, each full-time employee of Powertel as of
December 31, 2000 will receive a $3,000 cash bonus three months following the
completion of the Deutsche Telekom/Powertel or VoiceStream/Powertel merger, as
the case may be, if they remain employed in good standing as of that date or if
their employment is terminated as a result of job elimination resulting from the
Deutsche Telekom/Powertel or VoiceStream/Powertel merger, as the case may be.
The bonus will be prorated for part-time employees and employees hired after
December 31, 2000. In addition, approximately 150-300 key employees of Powertel,
including the executive officers of Powertel, will be eligible to receive
retention bonuses paid out of a $20 million bonus pool in amounts and upon terms
mutually agreed upon by the chief executive officers and chief operating
officers of VoiceStream and Powertel. These retention bonuses will be paid as
follows: 33.3% of the cash bonus 90 days after the Deutsche Telekom/Powertel or
VoiceStream/Powertel merger, 33.3% of the cash bonus on the first anniversary of
the Deutsche Telekom/Powertel or VoiceStream/Powertel merger and 33.4% on the
second anniversary of the Deutsche Telekom/Powertel or VoiceStream/Powertel
merger to those employees who remain employed in good standing on such dates.

     Incentive Bonus Plan

     Deutsche Telekom or VoiceStream, as the case may be, intends to pay
incentive bonuses out of a separate $20 million bonus pool to the same employees
that participate in the retention bonus plan, which may include selected
executive officers of Powertel. These individuals will be eligible to receive
incentive bonuses based on the achievement of specified performance targets for
the Powertel markets. The chief executive officers and chief operating officers
of VoiceStream and Powertel will mutually agree upon the incentive bonus for
each participant. Incentive bonuses will be paid as follows:

     - 12.5% is payable in January 2002, based upon achieving a minimum number
       of net subscriber additions and a minimum number of post-pay subscribers
       during the first quarter of 2001;

     - 12.5% is payable in January 2002, based upon achieving a minimum number
       of net subscriber additions and a minimum number of post-pay subscribers
       during the second quarter of 2001;

     - 12.5% is payable in January 2002 based upon achieving a minimum number of
       net subscriber additions and a minimum number of post-pay subscribers
       during the third quarter of 2001;

     - 12.5% is payable in January 2002 based upon achieving a minimum number of
       net subscriber additions and a minimum number of post-pay subscribers
       during the fourth quarter of 2001;

     - 6.25% is payable in January 2002 for each calendar quarter during 2001 in
       which combined pre-pay and post-pay churn is at or below a targeted
       percentage; and

     - 6.25% is payable in January 2002 for each calendar quarter during 2001 in
       which bad debt is at or below a targeted percentage of total subscriber
       revenue.

The incentive bonuses earned under this plan will depend on the number of
quarters during which performance targets are met. To earn any payments under
this plan, participants must be continuously employed by Powertel through the
payment date.

     Severance Plan

     Individuals who are employees of Powertel immediately before the closing of
the applicable merger and whose employment is terminated by Deutsche Telekom or
VoiceStream, as the case may be, because of a job elimination resulting from the
applicable merger will participate in the severance plan. Any payments under the
severance plan will be reduced dollar for dollar by any amounts that a
participant receives under the cash retention or incentive bonus plan, described
above. Under the severance plan, the chief executive officer, chief financial
officer, chief operating officer and all other executive vice presidents of
Powertel would receive severance equal to one year of their base salary plus
their targeted bonus as of August 26, 2000. Vice presidents of Powertel would
receive a severance payment equal to six months of their base salary plus their
targeted bonus as of August 26, 2000. All other employees would receive
severance equal to their base salary (or hourly equivalent), not including
overtime, plus their targeted bonus as of August 26, 2000 for a minimum of four
weeks, plus two weeks per year of service, up to a maximum of 20 weeks. To
obtain benefits under the severance plan, employees will be required to sign and
deliver to the surviving corporation a full release of all claims against
Powertel, Deutsche Telekom and VoiceStream and all related parties.

     Completion Bonus

     Each of the Deutsche Telekom/Powertel merger agreement and the
VoiceStream/Powertel merger agreement provides for the payment to specified
officers of Powertel of completion bonuses upon the closing date of the
applicable merger. The president and chief executive officer of Powertel, Allen
E. Smith, would receive a completion bonus of $2,450,125, the chief financial
officer of Powertel, Fred G. Astor, Jr., would receive a completion bonus of
$1,660,027 and the chief operating officer of Powertel, Rodney D. Dir, would
receive a completion bonus of $676,240 upon the closing of the applicable
merger.

     Indemnification of Directors and Officers

     Deutsche Telekom or VoiceStream, as the case may be, has agreed to cause
the surviving corporation in the applicable merger to maintain, for a period of
six years after the completion of the applicable merger, Powertel's current
provisions and policies regarding indemnification of officers and directors,
provided that the applicable surviving corporation may substitute policies
having at least the same coverage and containing terms that are no less
advantageous to the insured. If the premium for such substitute policy would
otherwise exceed 250% of the current premium, the surviving corporation need
only obtain as much insurance as can be obtained for 250% of the current
premium. In addition, Deutsche Telekom or VoiceStream, as the case may be, and
Powertel have agreed to indemnify the officers and directors of Powertel to the
fullest extent permitted by law. For more information, see "Summary of Deutsche
Telekom/Powertel and VoiceStream/Powertel Transaction Documents -- The Deutsche
Telekom/Powertel Merger Agreement -- Indemnification and Insurance" and "Summary
of Deutsche Telekom/Powertel and VoiceStream/Powertel Transaction
Documents -- The VoiceStream/Powertel Merger Agreement -- Indemnification and
Insurance."

     Stockholder Agreements

     In connection with the execution of the Deutsche Telekom/Powertel merger
agreement and the VoiceStream/Powertel merger agreement, a number of Powertel
stockholders entered into agreements with Deutsche Telekom and VoiceStream,
respectively, regarding the voting and transfer of their Powertel shares. Some
of these Powertel stockholders are, or have relationships with, directors or
executive officers of Powertel, as follows:

     - ITC Holding Company, Inc., which is an employer of directors Campbell B.
       Lanier, III and William H. Scott, III, and which has directors O. Gene
       Gabbard, Donald W. Burton and Donald W. Weber on its board of directors;

     - SCANA Corporation, which is the sole stockholder of SCANA Communications
       Holdings, Inc. and is the employer of directors William B. Timmerman and
       Ann M. Milligan; and

     - The South Atlantic Venture Funds and The Burton Partnerships, each of
       which employs director Donald W. Burton.

     These stockholder agreements are described in greater detail under "Summary
of Deutsche Telekom/Powertel and VoiceStream/Powertel Transaction
Documents -- Deutsche Telekom's Agreements with Stockholders of Powertel" and
"Summary of Deutsche Telekom/Powertel and VoiceStream/Powertel Transaction
Documents -- VoiceStream's Agreements with Stockholders of Powertel."

APPRAISAL RIGHTS

     Delaware law does not entitle the record holders of Powertel common shares
to rights of appraisal in connection with either the Deutsche Telekom/Powertel
merger or the VoiceStream/Powertel merger. Delaware law entitles the record
holders of Powertel preferred shares who follow the procedures specified in
Section 262 of the Delaware corporation law to have their shares appraised by
the Delaware Court of Chancery and to receive the "fair value" of these Powertel
preferred shares as of the time the Deutsche Telekom/Powertel merger or the
VoiceStream/Powertel merger, as the case may be, is completed, as may be
determined by the court, in place of the applicable merger consideration. In
order to exercise such rights, a stockholder must demand and perfect the rights
in accordance with Section 262, a copy of which is attached as Annex G to this
document. However, all holders of Powertel preferred shares have agreed to waive
their appraisal rights and to vote their shares in favor of the Deutsche
Telekom/Powertel merger and the VoiceStream/Powertel merger.

                                   DIVIDENDS

DEUTSCHE TELEKOM

     Deutsche Telekom historically has paid dividends on an annual basis and
expects to continue to pay annual dividends on Deutsche Telekom ordinary shares.
The amount of future Deutsche Telekom dividends will be dependent upon Deutsche
Telekom's earnings and financial condition and other factors affecting Deutsche
Telekom's businesses. Deutsche Telekom's dividend for the year ended December
31, 1999 was 0.62 euros per Deutsche Telekom ordinary share or $0.58 per
Deutsche Telekom ADS (based on the noon buying rate for the dividend payment
date, which occurred during the second quarter of 2000). See "Market Price and
Dividend Data -- Dividend Data -- Deutsche Telekom."

     Holders of Deutsche Telekom ordinary shares receive dividends in euros.
Deutsche Telekom's ADS depositary generally will convert dividends received in
respect of Deutsche Telekom ordinary shares represented by Deutsche Telekom ADSs
into U.S. dollars and distribute the dividends in U.S. dollars to holders of
Deutsche Telekom ADSs. See "Description of Deutsche Telekom American Depositary
Shares -- Dividends and Distributions."

VOICESTREAM

     VoiceStream has never declared or paid dividends on VoiceStream common
shares and does not anticipate paying dividends in the foreseeable future. In
addition, provisions of VoiceStream's credit facility and the indentures for its
senior notes and senior discount notes and the senior notes issued by Omnipoint,
contain restrictions on VoiceStream's ability to declare and pay dividends on
VoiceStream common shares.

               FEDERAL SECURITIES LAW CONSEQUENCES OF THE MERGERS

THE DEUTSCHE TELEKOM/VOICESTREAM MERGER AND THE DEUTSCHE TELEKOM/POWERTEL MERGER

     Deutsche Telekom ADSs and Deutsche Telekom ordinary shares received in the
Deutsche Telekom/ VoiceStream merger by VoiceStream stockholders and in the
Deutsche Telekom/Powertel merger by Powertel stockholders, as the case may be,
generally will be freely transferable except that:

     - Deutsche Telekom ADSs and Deutsche Telekom ordinary shares received by
       persons that are deemed to be affiliates of VoiceStream or Powertel under
       the Securities Act at the time of the VoiceStream or Powertel special
       meeting, as the case may be, may be resold by them only in transactions
       permitted by Rule 145 under the Securities Act or as otherwise permitted
       under the Securities Act. Persons that may be deemed to be affiliates of
       VoiceStream or Powertel for purposes of Rule 145 under the Securities Act
       generally include individuals or entities that control, are controlled by
       or are under common control with VoiceStream or Powertel, as the case may
       be, and include directors and executive officers of VoiceStream or
       Powertel. Each of the Deutsche Telekom/VoiceStream merger agreement and
       the Deutsche Telekom/Powertel merger agreement requires each of
       VoiceStream and Powertel, respectively, to use its reasonable best
       efforts to cause each of its respective affiliates to deliver to Deutsche
       Telekom on or prior to the completion of the applicable merger, a signed
       agreement to the effect that the affiliate will not offer, sell or
       otherwise dispose of any Deutsche Telekom ADSs or Deutsche Telekom
       ordinary shares issued to the affiliate in the applicable merger in
       violation of the Securities Act or the related SEC rules.

     - In addition, certain VoiceStream and Powertel stockholders who entered
       into stockholder agreements with Deutsche Telekom described under
       "Summary of the Deutsche Telekom/ VoiceStream Transaction
       Documents -- Deutsche Telekom's Agreements with Stockholders of
       VoiceStream" and "Summary of Deutsche Telekom/Powertel and
       VoiceStream/Powertel Transaction Documents -- Deutsche Telekom's
       Agreement with Stockholders of Powertel" will be subject to certain
       resale restrictions on their shares for the first six months after the
       completion of the Deutsche Telekom/VoiceStream merger or the Deutsche
       Telekom/Powertel merger, as the case may be.

THE VOICESTREAM/POWERTEL MERGER

     VoiceStream shares received in the VoiceStream/Powertel merger by Powertel
stockholders generally will be freely transferable, except that:

     - VoiceStream shares received by persons that are deemed to be affiliates
       of Powertel under the Securities Act at the time of the Powertel special
       meeting may be resold by them only in transactions permitted by Rule 145
       under the Securities Act or as otherwise permitted under the Securities
       Act. Persons that may be deemed to be affiliates of Powertel for these
       purposes generally include individuals or entities that control, are
       controlled by or are under common control with Powertel and include
       directors and executive officers of Powertel. The VoiceStream/Powertel
       merger agreement requires Powertel to use reasonable efforts to cause
       each of its affiliates to deliver to VoiceStream on or prior to the
       completion of the VoiceStream/Powertel merger a signed agreement to the
       effect that the affiliate will not offer, sell or otherwise dispose of
       any VoiceStream shares issued to the affiliate in the
       VoiceStream/Powertel merger in violation of the Securities Act or the
       related SEC rules.

     - In addition, certain Powertel stockholders who have agreed in the
       stockholder agreements with VoiceStream described under "Summary of
       Deutsche Telekom/Powertel and VoiceStream/ Powertel Transaction
       Documents -- VoiceStream's Agreements with Stockholders of Powertel" will
       be subject to certain resale restrictions on their VoiceStream shares
       prior to the six month anniversary of the closing of the
       VoiceStream/Powertel merger.

OTHER EFFECTS OF THE DEUTSCHE TELEKOM/VOICESTREAM MERGER AND THE DEUTSCHE
TELEKOM/POWERTEL MERGER

     Listing of Shares

     It is a condition to each of the Deutsche Telekom/VoiceStream merger and
the Deutsche Telekom/ Powertel merger that the Deutsche Telekom ADSs issuable in
connection with the Deutsche Telekom/ VoiceStream merger or the Deutsche
Telekom/Powertel merger, as the case may be, be authorized for listing on the
NYSE subject to official notice of issuance, and that all steps necessary for
the listing of the Deutsche Telekom ordinary shares to be issued by Deutsche
Telekom in connection with the Deutsche Telekom/VoiceStream merger and the
Deutsche Telekom/Powertel merger, as the case may be, on the Frankfurt Stock
Exchange will have been taken. If the Deutsche Telekom/VoiceStream merger or the
Deutsche Telekom/Powertel merger, as the case may be, is completed, the newly
issued Deutsche Telekom ordinary shares will be listed on the Frankfurt Stock
Exchange and dealings in the Deutsche Telekom ordinary shares are expected to
commence, at 09:00 a.m., Frankfurt time, on or about the third business day
after the relevant merger is legally completed. For information concerning tax
considerations related to the ownership of Deutsche Telekom ADSs and Deutsche
Telekom ordinary shares, see "U.S. and German Federal Tax Consequences -- U.S.
Federal Income Tax and German Tax Considerations for U.S. Resident Holders."

     Effects on Other Capital Stock and Warrants of VoiceStream

     Any 7% cumulative convertible preferred shares of Omnipoint, a subsidiary
of VoiceStream, that are outstanding at the time of the Deutsche
Telekom/VoiceStream merger will remain outstanding after the completion of the
Deutsche Telekom/VoiceStream merger. Any warrants issued pursuant to the
Omnipoint remainder warrant certificate dated May 6, 1997 that are not exercised
before the completion of the Deutsche Telekom/VoiceStream merger will remain
outstanding after completion of the Deutsche Telekom/VoiceStream merger. Any
VoiceStream voting preferred shares, all of which are held by Deutsche Telekom,
will remain outstanding and will be unaffected by the Deutsche
Telekom/VoiceStream merger. For additional details concerning these classes of
VoiceStream shares and warrants, see "Summary of the Deutsche
Telekom/VoiceStream Transaction Documents -- The Deutsche Telekom/VoiceStream
Merger Agreement -- Treatment of Other Capital Stock and Warrants."

     Effects on Warrants of Powertel

     Any warrants issued pursuant to the Warrant Agreement, dated February 7,
1996, between Powertel and Bankers Trust Company, as warrant agent, that have
not been exercised before the completion of the Deutsche Telekom/Powertel merger
will remain outstanding after the Deutsche Telekom/Powertel merger. For
additional details concerning these warrants, see "Summary of Deutsche
Telekom/Powertel and VoiceStream/Powertel Transaction Documents -- The Deutsche
Telekom/Powertel Merger Agreement -- Treatment of Powertel Warrants."

     Content and Timing of Reports and Notices of the Companies; Definition of
Foreign Private Issuer

     The content and timing of reports and notices that Deutsche Telekom files
with the SEC differ in several respects from the reports and notices that
VoiceStream and Powertel currently file with the SEC. Deutsche Telekom is a
foreign private issuer for the purposes of the reporting rules under the
Securities Exchange Act of 1934, as amended.

     As United States reporting companies, VoiceStream and Powertel currently
must each file with the SEC, among other reports and notices:

     (1) an annual report on Form 10-K within 90 days after the end of each
         fiscal year;

     (2) a quarterly report on Form 10-Q within 45 days after the end of each
         fiscal quarter; and

     (3) current reports on Form 8-K upon the occurrence of various corporate
         events.
                                       102
<PAGE>   121

     As a foreign private issuer, pursuant to the requirements of the Exchange
Act, Deutsche Telekom is required to:

     (1) file with the SEC an annual report on Form 20-F within six months after
         the end of each fiscal year; and

     (2) furnish material information that it makes public in Germany on Form
         6-K.

     As a foreign private issuer, Deutsche Telekom is not required under the
Exchange Act to file quarterly reports on Form 10-Q after the end of each
financial quarter.

     In addition, the content and timing of reports and notices that holders of
Deutsche Telekom ADSs and Deutsche Telekom ordinary shares will receive will
differ from the reports and notices that currently are received by VoiceStream
and Powertel stockholders. As United States reporting companies, VoiceStream and
Powertel each must mail to its respective stockholders in advance of each annual
meeting of stockholders:

     (1) an annual report containing audited financial statements; and

     (2) a proxy statement that complies with the requirements of the Exchange
         Act.

     As a foreign private issuer, Deutsche Telekom is exempt from the rules
under the Exchange Act prescribing the furnishing and content of annual reports
and proxy statements to its shareholders. Deutsche Telekom expects to retain its
status as a foreign private issuer after the completion of the Deutsche
Telekom/VoiceStream merger and the Deutsche Telekom/Powertel merger. Under SEC
rules, Deutsche Telekom will retain its status as a foreign private issuer
unless:

     (1) more than 50% of Deutsche Telekom's ordinary shares, including Deutsche
         Telekom ordinary shares underlying Deutsche Telekom ADSs, are, directly
         or indirectly, owned of record by shareholders that are residents of
         the United States; and

     (2) any one of the following conditions is satisfied:

        - the majority of Deutsche Telekom's directors or executive officers are
          United States citizens or residents of the United States;

        - more than 50% of Deutsche Telekom's assets are located in the United
          States; or

        - Deutsche Telekom's business is administered principally in the United
          States.

     After completion of the Deutsche Telekom/VoiceStream and Deutsche
Telekom/Powertel mergers, it is possible that United States shareholders may at
some time in the future hold more than 50% of Deutsche Telekom's ordinary
shares, including Deutsche Telekom ordinary shares underlying the Deutsche
Telekom ADSs. However, Deutsche Telekom expects that after the Deutsche
Telekom/VoiceStream merger and Deutsche Telekom/Powertel merger, at least 50% of
its directors and executive officers will be persons that are not United States
citizens or residents and, on a consolidated basis, at least 50% of its assets
will be located outside of the United States. Furthermore, Deutsche Telekom will
continue to administer its business from its current headquarters in Germany.
Accordingly, Deutsche Telekom expects to retain its status as a foreign private
issuer after completion of the Deutsche Telekom/VoiceStream and Deutsche
Telekom/Powertel mergers.

     If Deutsche Telekom at any time loses its status as a foreign private
issuer, it would be required to file annual reports on Form 10-K, quarterly
reports on Form 10-Q and current reports on Form 8-K. In addition, Deutsche
Telekom would become subject to the rules under the Exchange Act regarding the
furnishing and content of annual reports and proxy statements to its
shareholders and forefeiture by its directors, officers and beneficial owners of
10% or more of its shares of any "short swing" profits realized by them from any
purchases and sales of Deutsche Telekom shares within a six-month period.

     Although Deutsche Telekom, as a foreign private issuer, is exempt from the
rules under the Exchange Act regarding the furnishing of annual reports to
shareholders, under the rules of the NYSE, Deutsche

                                       103
<PAGE>   122

Telekom is required to distribute to the holders of its ADSs an annual report
containing audited financial statements a reasonable period of time before
Deutsche Telekom's annual general meeting of shareholders. Deutsche Telekom
currently furnishes holders of its ordinary shares with Deutsche Telekom's
annual report, which contains audited financial statements prepared in
conformity with German GAAP, including U.S. GAAP reconciliations. Deutsche
Telekom also furnishes holders of its ordinary shares with quarterly interim
reports, which include unaudited interim financial information prepared in
conformity with German GAAP, including U.S. GAAP reconciliations, and notices of
meetings of shareholders and related documents in accordance with the rules
German Stock Corporation Act (Aktiengesetz) and the Frankfurt Stock Exchange.
See "Description of Deutsche Telekom American Depositary Shares." and
"Comparison of Rights of VoiceStream and Powertel Stockholders and Deutsche
Telekom Share Owners Reporting Requirements."

     Delisting of VoiceStream and Powertel Common Shares

     If the Deutsche Telekom/VoiceStream merger is completed, the VoiceStream
common shares will be delisted from the Nasdaq Stock Market and deregistered
under the Exchange Act. The Powertel common shares will be delisted from the
Nasdaq Stock Market and deregistered under the Exchange Act if the Deutsche
Telekom/Powertel merger is completed.

     Potential effects on Trading in Deutsche Telekom ADSs and Deutsche Telekom
ordinary shares

     Some U.S. mutual funds, state pension funds and other investors are not
permitted to hold equity securities of non-U.S. companies. In addition, some
mutual funds and other investors may hold shares of VoiceStream because it is
included in the Nasdaq 100 Index, and Deutsche Telekom shares are not included
in that index. Any sales by these holders could affect the market price of the
Deutsche Telekom ADSs or Deutsche Telekom ordinary shares.

     After the completion of the Deutsche Telekom/VoiceStream and Deutsche
Telekom/Powertel mergers, the relative weight of Deutsche Telekom in the DAX
Index of German securities, which is capped at 15%, will not change and will be
re-set to 15% each quarter. Deutsche Telekom's weighting in the Pan-European
indices (DJ-STOXX and MSCI), which are not subject to the same limitations, will
increase. As a result, pension funds, unit trusts and other investment vehicles
whose investment objective is to track the performance of any of these indices
are likely to increase their holdings of Deutsche Telekom ordinary shares, which
may counterbalance the adverse effect on the market price for the Deutsche
Telekom ADSs or Deutsche Telekom ordinary shares caused by some of the factors
described above.

  Deutsche Telekom Financial Information

     Deutsche Telekom prepares its financial statements in accordance with
German GAAP and presents them in euros. Deutsche Telekom financial statements
include a reconciliation of the German GAAP financial information to U.S. GAAP,
and Deutsche Telekom's annual financial statements contain a summary of the
effects of the differences between German GAAP and U.S. GAAP in accordance with
SEC rules.

     If Deutsche Telekom loses its status as a foreign private issuer, under SEC
rules, it will be required to prepare financial statements in accordance with
U.S. GAAP and present them in U.S. dollars, in addition to its financial
statements prepared in accordance with German GAAP and presented in euros. Note
36 to Deutsche Telekom's Annual Report on Form 20-F for the year ended December
31, 1999 describes the significant differences between German GAAP and U.S. GAAP
as they relate to Deutsche Telekom. The notes to the unaudited pro forma
condensed consolidated financial information, prepared in accordance with German
GAAP, set forth a summary of certain estimated adjustments that would be
required if U.S. GAAP had been applied to that information.

     Dilution of the German Government's Ownership Interest in Deutsche
Telekom.  After the completion of the Deutsche Telekom/VoiceStream merger, the
aggregate ownership of Deutsche Telekom shares by the Federal Republic of
Germany and KfW is expected to be diluted to approximately 46% and after the
completion of the Deutsche Telekom/VoiceSteam merger and the Deutsche
Telekom/Powertel
                                       104
<PAGE>   123

merger, the aggregate ownership of Deutsche Telekom shares by the Federal
Republic of Germany and KfW is expected to be diluted to approximately 44.5%.
The Federal Republic of Germany has publicly stated its intention to reduce
substantially its ownership of Deutsche Telekom shares.

OTHER EFFECTS OF THE VOICESTREAM/POWERTEL MERGER

     Listing of Shares

     It is a condition to the VoiceStream/Powertel merger that VoiceStream
common shares issuable in connection with the VoiceStream/Powertel merger be
authorized for listing on the Nasdaq Stock Market subject to official notice of
issuance.

     Effects On Other Capital Stock and Warrants

     At the completion of the VoiceStream/Powertel merger, each Powertel
preferred share will be converted into the right to receive a number of
VoiceStream common shares determined by multiplying the Conversion Number by the
sum of (1) the number of Powertel common shares into which such Powertel
preferred share would be converted as of the completion of the
VoiceStream/Powertel merger plus (2) with respect to Powertel's Series E
preferred shares and Series F preferred shares, the number of Powertel common
shares that represent accrued or declared but unpaid dividends on these Powertel
preferred shares. Any warrants granted pursuant to the warrant agreement dated
February 2, 1996 between Powertel and Bankers Trust Company as warrant agent
that are not exercised before the completion of the VoiceStream/Powertel merger
will remain outstanding after completion of the VoiceStream/Powertel merger. For
additional details concerning these classes of shares and warrants, see "Summary
of Deutsche Telekom/Powertel and VoiceStream/Powertel Transaction
Documents -- The VoiceStream/Powertel Merger Agreement -- Treatment of Powertel
Warrants" and "-- Treatment of Powertel Options and Restricted Stock."

     Delisting of Powertel Common Shares

     If the VoiceStream/Powertel merger is completed, Powertel common shares
will be delisted from the Nasdaq Stock Market and deregistered under the
Exchange Act.

                              REGULATORY APPROVALS

REGULATORY APPROVALS REQUIRED FOR THE DEUTSCHE TELEKOM/VOICESTREAM MERGER AND
THE DEUTSCHE TELEKOM/POWERTEL MERGER

     U.S. Antitrust

     Under the HSR Act, as amended, we cannot complete the initial investment by
Deutsche Telekom in VoiceStream, the Deutsche Telekom/VoiceStream merger or the
Deutsche Telekom/Powertel merger until, with respect to each, (1) we have given
notification and furnished information to the FTC and the Antitrust Division of
the DOJ relating to the operations of the parties and (2) the 30-day waiting
period under HSR Act has expired or early termination of the waiting period has
occurred. Expiration of the

                                       105
<PAGE>   124

applicable waiting period (as it may be extended by a request for additional
information) under the HSR Act is a condition to completing each transaction.

     In August 2000, we filed with the FTC and the DOJ premerger notifications
and report forms relating to both the initial investment in VoiceStream and the
Deutsche Telekom/VoiceStream merger. The HSR Act waiting periods relating to
both transactions expired without the issuance of a request for additional
information. On September 12, 2000, we filed with the FTC and the DOJ premerger
notifications and report forms relating to the Deutsche Telekom/Powertel merger.
The DOJ, which is the reviewing agency for this transaction, will have 30 days
from that date, or until midnight on October 12, 2000, to decide whether to
issue a request for additional information. If a request for additional
information is made, then the Deutsche Telekom/Powertel merger may not be
completed until 20 days after the merging parties certify substantial compliance
with the request, which may take several months. If the DOJ does not issue such
a request, the HSR Act waiting period will expire at the end of the 30-day
period, or sooner if the DOJ grants early termination of the period.

     Termination of the HSR Act waiting period does not prevent the government
from challenging the initial investment or either merger. At any time before or
after the completion of any of the transactions, the DOJ or FTC could take any
action under the antitrust laws that it deems necessary or desirable in the
public interest, including seeking the divestiture of substantial assets of
Deutsche Telekom, VoiceStream, or Powertel, or seeking to block any of the
transactions. In addition, certain private parties as well as state attorneys
general and other antitrust authorities may challenge the transactions under
antitrust laws under certain circumstances, and, even though we believe we
should prevail, we cannot assure you that we will prevail. Although we do not
anticipate that the DOJ or FTC will challenge the initial investment in
VoiceStream, the Deutsche Telekom/VoiceStream merger or the Deutsche
Telekom/Powertel merger, we cannot assure you that a challenge to any of these
transactions on antitrust grounds will not be made, or, if a challenge is made,
what the result will be.

     FCC

     The Deutsche Telekom/VoiceStream merger and the Deutsche Telekom/Powertel
merger are subject to the requirements of the Communications Act of 1934, as
amended, and the rules, regulations and policies of the FCC. Before each of the
mergers may occur, the FCC must give its consent based on a determination that
the merger would serve the public interest, convenience and necessity. In making
this determination, the FCC examines whether a proposed merger is consistent
with the Communications Act and the FCC's rules, regulations and policies,
including, among other things, the effect of the proposed transfer on FCC
policies encouraging competition. In addition, before a non-U.S. company
acquires a U.S. company that indirectly holds FCC licenses, the FCC must
specifically determine that such foreign ownership is in the public interest.
The FCC has adopted a strong presumption in favor of indirect foreign
investments by entities from World Trade Organization member countries such as
Germany, absent competition or national security or law enforcement concerns.

     The Deutsche Telekom/VoiceStream and Deutsche Telekom/Powertel merger
applications were filed with the FCC on September 18, 2000, and we anticipate
that public comments will be due on the applications during November 2000. A
final decision by the FCC on a transaction of this scope generally takes at
least six months from filing and may take substantially longer. While we believe
that both mergers should be approved under the standards discussed in the prior
paragraph, we expect that the merger applications will be opposed, and we cannot
assure you that the FCC will approve them. It is also possible that the FCC will
condition its approval on compliance with competitive safeguards, and that any
FCC approval will be challenged in court. Legislation has also been introduced
in the U.S. Congress that, if enacted, might prevent the FCC from approving
either merger.

     Exon-Florio

     The provisions of the Exon-Florio amendment to the Omnibus Trade and
Competitiveness Act of 1988 authorize the President to investigate and, if he
deems it necessary, to suspend or prohibit any

                                       106
<PAGE>   125

"merger, acquisition or takeover" of a U.S. company that would result in foreign
control of the company, where such control would "threaten to impair the
national security." The President has delegated his authority to receive notices
of transactions and to conduct investigations to the Committee on Foreign
Investment, an interagency committee chaired by the Secretary of the Treasury.

     A party or parties to a transaction may, but are not required to, submit to
the Committee on Foreign Investment a voluntary notice of the transaction. In
general, if the parties submit such a notice, the Committee on Foreign
Investment has 30 days in which to make an initial determination whether to
conduct an investigation. If the Committee on Foreign Investment decides that an
investigation is warranted, it typically has 45 days in which to complete the
investigation and make a recommendation to the President, including whether to
take action to prohibit the merger. If the Committee on Foreign Investment
declines to initiate a 45-day investigation, the Committee on Foreign Investment
review process concludes and the transaction is, in effect, approved.

     Deutsche Telekom and VoiceStream intend to submit a joint voluntary notice
to the Committee on Foreign Investment. Deutsche Telekom and Powertel also
intend to submit a joint voluntary notice to the Committee on Foreign
Investment. Although we do not anticipate that the Committee on Foreign
Investment will recommend that the President suspend or prohibit the Deutsche
Telekom/VoiceStream merger or the Deutsche Telekom/Powertel merger, we cannot
assure you that such a recommendation will not be made, or assure you what the
result will be if such recommendation is made.

     General

     It is possible that one or more of the regulatory approvals required to
complete the Deutsche Telekom/VoiceStream merger or the Deutsche
Telekom/Powertel merger will not be obtained on a timely basis or at all. In
addition, it is possible that any of the governmental entities with which
filings are made may seek regulatory conditions for granting approval of the
Deutsche Telekom/VoiceStream merger or the Deutsche Telekom/Powertel merger.

     Under the Deutsche Telekom/VoiceStream merger agreement, Deutsche Telekom
and VoiceStream have each agreed to use reasonable best efforts to complete the
Deutsche Telekom/VoiceStream merger, including to gain clearance from antitrust
and competition authorities and obtain other required approvals. For this
purpose, Deutsche Telekom and VoiceStream have also agreed to accept any
actions, conditions, terms or restrictions necessary to obtain any regulatory
approval, unless those conditions, terms and restrictions amount to a
"burdensome condition," as that term is used in the Deutsche Telekom/VoiceStream
merger agreement. The meaning of "burdensome condition" is explained below under
"Summary of the Deutsche Telekom/VoiceStream Transaction Documents -- The
Deutsche Telekom/VoiceStream Merger Agreement -- Important Definitions."
Although we do not expect regulatory authorities to raise any significant
objections to the Deutsche Telekom/VoiceStream merger, we cannot be certain that
we will obtain all required regulatory approvals or that these approvals will
not contain terms, conditions or restrictions that would be detrimental to
Deutsche Telekom or its telecommunications business after the Deutsche
Telekom/VoiceStream merger. If a burdensome condition is imposed, we cannot
assure you that we will terminate the Deutsche Telekom/VoiceStream merger.

     Under the Deutsche Telekom/Powertel merger agreement, Deutsche Telekom and
Powertel have each agreed to use reasonable best efforts to complete the
Deutsche Telekom/Powertel merger, including to gain clearance from antitrust and
competition authorities and obtain other required approvals, provided that
neither Deutsche Telekom nor any of its subsidiaries is required to and neither
Powertel nor its subsidiaries is permitted to, without the consent of Deutsche
Telekom, divest or hold separate or otherwise take any action that limits
Deutsche Telekom's freedom of action with respect to Deutsche Telekom, Powertel,
VoiceStream or any of their respective subsidiaries or any of their business,
product lines or assets. For this purpose, Deutsche Telekom and Powertel have
also agreed to accept any actions, conditions, terms or restrictions necessary
to obtain any regulatory approval, unless those actions, conditions, terms and
restrictions would reasonably be expected to have a "material adverse effect,"
as that term is used in the Deutsche Telekom/Powertel merger agreement. The
meaning of "material adverse

                                       107
<PAGE>   126

effect" is explained below under "Summary of Deutsche Telekom/Powertel and
VoiceStream/Powertel Transaction Documents -- The Deutsche Telekom/Powertel
Merger Agreement -- Important Definition." Although we do not expect regulatory
authorities to raise any significant objections to the Deutsche Telekom/Powertel
merger, we cannot be certain that we will obtain all required regulatory
approvals or that these approvals will not contain terms, conditions or
restrictions that would be detrimental to Deutsche Telekom. If a condition that
would reasonably be expected to have a material adverse effect is imposed, we
cannot assure you that we will terminate the Deutsche Telekom/Powertel merger.

REGULATORY APPROVALS REQUIRED FOR THE VOICESTREAM/POWERTEL MERGER

     U.S. Antitrust

     Under the HSR Act, VoiceStream and Powertel cannot complete the
VoiceStream/Powertel merger until (1) VoiceStream and Powertel have given
notification and furnished information relating to the operations of VoiceStream
and Powertel to the FTC and the DOJ and (2) the 30-day waiting period expires or
is terminated early. Expiration of the applicable waiting period (as it may be
extended by a request for additional information) under the HSR Act is a
condition to completing the VoiceStream/Powertel merger.

     On September 13, 2000, VoiceStream or Powertel filed with the FTC and the
DOJ a premerger notification and report form relating to the
VoiceStream/Powertel transaction. The DOJ, which is the reviewing agency for
this transaction, will have 30 days from that date, or until midnight on October
12, 2000, to decide whether to issue a request for additional information. If a
request for additional information is made, then the VoiceStream/Powertel merger
may not be completed until 20 days after the merging parties certify substantial
compliance with the request, which may take several months. If the DOJ does not
issue such a request, the HSR Act waiting period will expire at the end of the
30-day period or sooner if the agency grants the early termination period.

     Termination of the HSR waiting period does not prevent the government from
challenging the VoiceStream/Powertel merger. At any time before or after the
completion of the VoiceStream/Powertel merger, the FTC or DOJ could take any
action under the antitrust laws that it deems necessary or desirable in the
public interest, including seeking the divestiture of substantial assets of
VoiceStream or Powertel or seeking to block the VoiceStream/Powertel merger. In
addition, certain private parties as well as state attorneys general and other
antitrust authorities may challenge the acquisition under antitrust laws or
other circumstances, and even if VoiceStream and Powertel believe that they
should prevail, there can be no assurances that they will prevail. Although
VoiceStream and Powertel do not anticipate that the Department of Justice will
challenge the VoiceStream/Powertel merger, VoiceStream and Powertel can give no
assurance that a challenge to the VoiceStream/Powertel merger on antitrust
grounds will not be made, or, if a challenge is made, what the result will be.

     FCC

     The VoiceStream/Powertel merger is subject to the requirements of the
Communications Act of 1934, as amended, and the rules, regulations and policies
of the FCC. Before the VoiceStream/Powertel merger may occur, the FCC must give
its consent based on a determination that the VoiceStream/Powertel merger would
serve the public interest, convenience and necessity. In making this
determination, the FCC examines whether a proposed merger is consistent with the
Communications Act and the FCC's rules, regulations and policies, including,
among other things, the effect of the transfer on FCC policies encouraging
competition.

     The VoiceStream/Powertel merger application was filed with the FCC on
September 18, 2000, and VoiceStream and Powertel anticipate that public comment
will be due on it sometime in late October or during November 2000. Because
consummation of the VoiceStream/Powertel merger is conditioned upon the outcome
of the Deutsche Telekom/VoiceStream merger, VoiceStream and Powertel have
requested that the FCC process the VoiceStream/Powertel merger application
simultaneously with the Deutsche Telekom/VoiceStream and Deutsche
Telekom/Powertel merger applications. As noted above, a final decision by the
FCC on transactions the size of the three proposed mergers generally takes at
least six
                                       108
<PAGE>   127

months from filing and may take substantially longer. Accordingly, VoiceStream
and Powertel do not expect the FCC to render a decision regarding the
VoiceStream/Powertel merger application for at least six months. Furthermore,
while VoiceStream and Powertel believe that the VoiceStream/Powertel merger
application should be approved under the foregoing standard, they can give no
assurance that the FCC will approve it. It is also possible that the FCC will
condition its approval on compliance with competitive safeguards, and that any
FCC approval will be challenged in court.

     General

     It is possible that either or both of the regulatory approvals required to
complete the VoiceStream/Powertel merger will not be obtained on a timely basis
or at all. In addition, it is possible that either of the governmental entities
with which filings are made may seek regulatory conditions for granting approval
of the VoiceStream/Powertel merger.

     Under the VoiceStream/Powertel merger agreement, VoiceStream and Powertel
have each agreed to use reasonable best efforts to comply promptly with all
legal requirements, including furnishing all information required under the HSR
Act and all actions required in connection with approvals of or filings with the
FCC or similar agencies or any other governmental entities. Although VoiceStream
and Powertel do not expect regulatory authorities to raise any significant
objections to the VoiceStream/Powertel merger, VoiceStream and Powertel cannot
be certain that they will obtain all required regulatory approvals or that these
approvals will not contain terms, conditions or restrictions that would be
detrimental to VoiceStream or its telecommunications business after the
VoiceStream/Powertel merger. If a condition that would reasonably be expected to
have a material adverse effect is imposed, VoiceStream and Powertel cannot
assure you that they will terminate the VoiceStream/Powertel merger.

                    U.S. FEDERAL AND GERMAN TAX CONSEQUENCES

GENERAL

     The following sections contain separate discussions of:

     (1) U.S. federal income tax consequences of the Deutsche
         Telekom/VoiceStream merger to U.S. holders of VoiceStream common
         shares;

     (2) U.S. federal income tax consequences of the Deutsche Telekom/Powertel
         merger to U.S. holders of Powertel common shares;

     (3) U.S. federal income tax consequences of the VoiceStream/Powertel merger
         to U.S. holders of Powertel common shares;

     (4) U.S. federal income tax and German Tax considerations for U.S. resident
         holders of Deutsche Telekom ADSs and Deutsche Telekom ordinary shares;
         and

     (5) German tax considerations for non-German holders of Deutsche Telekom
         ADSs and Deutsche Telekom ordinary shares.

     General Matters Relating to U.S. Federal Income Tax Discussions

     As used in these discussions, the term "U.S. holder" means, before the
merger, a beneficial owner of VoiceStream common shares or Powertel common
shares, as applicable, or an employee stock option to acquire such shares, and,
after the merger, a beneficial owner of Deutsche Telekom ADSs or Deutsche
Telekom ordinary shares or VoiceStream common shares, as applicable, who is for
U.S. federal income tax purposes:

     - a citizen or resident of the United States;

     - a corporation created or organized in the United States or under the law
       of the United States or any state or the District of Columbia; or

     - a partnership, trust, or estate that is treated as a United States
       person.

     These discussions do not address all aspects of U.S. tax law that may be
relevant to a U.S. holder in light of his particular circumstances or who is
subject to special provisions of such law. For example, these discussions do not
address all aspects of U.S. tax law that may be relevant to U.S. holders:

     - who are liable for alternative minimum tax;

     - who hold their VoiceStream common shares, Powertel common shares,
       Deutsche Telekom ADSs, or Deutsche Telekom ordinary shares as part of a
       straddle, hedge, synthetic security, conversion transaction or other
       integrated investment composed of one or more other investments;

     - whose "functional currency" is not the U.S. dollar; or

     - who are financial institutions, insurance companies, tax-exempt
       organizations, traders in securities that elect mark-to-market accounting
       treatment, or broker-dealers.

     In addition, these discussions are limited to U.S. holders who hold their
VoiceStream common shares, Powertel common shares, Deutsche Telekom ADSs or
Deutsche Telekom ordinary shares as capital assets. The discussion also does not
address U.S. state or local taxation or taxation by countries other than the
United States and Germany.

     Further, these discussions do not address any tax consequences of the
Deutsche Telekom/Powertel merger or VoiceStream/Powertel merger to holders of
any class of Powertel preferred shares, nor does it address any tax consequences
of (1) a conversion of shares of any class of Powertel preferred shares into
Powertel common shares or (2) an exchange of shares of any class of Powertel
preferred shares or the right to receive any dividends in respect of any class
of Powertel preferred shares for Deutsche Telekom

                                       110
<PAGE>   129

ADSs or Deutsche Telekom ordinary shares or VoiceStream common shares. Holders
of each class of Powertel preferred shares are urged to consult with their own
tax advisors as to the tax consequences to them of the Deutsche Telekom/Powertel
merger and the VoiceStream/Powertel merger and the conversion or exchange of
Powertel preferred shares.

     The U.S. tax discussions are based on existing U.S. federal income tax law,
including statutes, regulations, administrative rulings, and court decisions,
all as in effect on the date of this proxy statement/prospectus. All of these
authorities are subject to change, or change in interpretation, possibly with
retroactive effect. These discussions assume that each merger will be completed
in accordance with the terms of the relevant merger agreement. Any change in any
of the foregoing authorities or failure of the assumption to be true could alter
the tax consequences discussed below. The parties will not request, and none of
the mergers is conditioned on, a ruling from the Internal Revenue Service as to
any of the U.S. federal income tax consequences of such merger. As a result,
there can be no assurance that the IRS will not disagree with or challenge any
of the conclusions set forth in the discussions.

     In these discussions, when we refer to the completion of any of the
mergers, we mean the effective time of those mergers, which occurs when a
certificate of merger is filed and becomes effective.

     Each VoiceStream shareholder and Powertel shareholder is urged to consult
his own tax advisor as to the U.S. federal income and other tax consequences to
him of the relevant merger, including the income tax consequences arising from
his own unique facts and circumstances, and including any estate, inheritance,
gift, state, local or non-U.S. tax consequences of the relevant merger.

U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE DEUTSCHE TELEKOM/VOICESTREAM MERGER
TO U.S. HOLDERS OF VOICESTREAM COMMON SHARES

     In the opinion of Jones, Day, Reavis & Pogue, tax counsel to VoiceStream,
and Wachtell, Lipton, Rosen & Katz, special counsel to VoiceStream, subject to
the limitations and qualifications set forth under the heading "U.S. Federal and
German Tax Consequences -- General," the discussion in this section sets forth
the material U.S. federal income tax consequences of the Deutsche
Telekom/VoiceStream merger to U.S. holders of VoiceStream common shares.

     Tax Opinion

     The obligation of VoiceStream to complete the Deutsche Telekom/VoiceStream
merger is conditioned on the receipt of an opinion from tax counsel to
VoiceStream and/or special counsel to VoiceStream substantially to the effect
that the Deutsche Telekom/VoiceStream merger will qualify as a reorganization
within the meaning of Section 368(a) of the U.S. tax code and that each transfer
of property to Deutsche Telekom by a shareholder of VoiceStream pursuant to the
Deutsche Telekom/VoiceStream merger will not be subject to Section 367(a)(1) of
the U.S. tax code. Counsel's tax opinion will be based on assumptions noted in
the opinion, including an assumption that any "five-percent transferee
shareholder" of Deutsche Telekom, as defined in Treasury regulations promulgated
under Section 367(a) of the U.S. tax code, will file a "gain recognition
agreement" as defined in such regulations, and on factual representations of
VoiceStream and Deutsche Telekom contained in certificates signed by officers of
VoiceStream and Deutsche Telekom to be delivered at the time of the Deutsche
Telekom/VoiceStream merger. VoiceStream does not intend to waive the receipt of
its counsel's opinion as a condition to its obligation to complete the Deutsche
Telekom/VoiceStream merger. Counsel's opinion will not be binding on the IRS or
any court.

     U.S. Holders Whose Merger Consideration Does Not Consist Solely of Cash

     For U.S. federal income tax purposes, assuming that the Deutsche
Telekom/VoiceStream merger will qualify as a reorganization within the meaning
of Section 368(a) of the U.S. tax code and that each transfer of property to
Deutsche Telekom by a shareholder of VoiceStream pursuant to the Deutsche

                                       111
<PAGE>   130

Telekom/VoiceStream merger will not be subject to Section 367(a)(1) of the U.S.
tax code, a U.S. holder of VoiceStream common shares whose merger consideration
does not consist solely of cash:

     - will not recognize any loss upon his receipt of merger consideration in
       the Deutsche Telekom/ VoiceStream merger, and

     - will recognize gain upon his receipt of merger consideration in the
       Deutsche Telekom/VoiceStream merger equal to the lesser of (1) the gain
       realized, if any, with respect to each VoiceStream common share exchanged
       and (2) the cash, if any, received for the VoiceStream common share.

     The amount of gain realized with respect to each VoiceStream common share
exchanged will equal the excess of (a) the sum of the fair market value at the
completion of the Deutsche Telekom/ VoiceStream merger of the Deutsche Telekom
ADSs or Deutsche Telekom ordinary shares and the cash, if any, received for the
share, over (b) the U.S. holder's tax basis in such share. As discussed further
below, different rules apply to any shareholder of VoiceStream who, immediately
after the Deutsche Telekom/VoiceStream merger, will be a "five-percent
transferee shareholder" of Deutsche Telekom, as defined in Treasury regulations
promulgated under Section 367(a) of the U.S. tax code, and to any cash received
in lieu of fractional shares in the Deutsche Telekom/VoiceStream merger. Any
recognized gain generally will be capital gain, and generally will be long-term
capital gain with respect to VoiceStream common shares held by the U.S. holder
for more than 12 months at the completion of the Deutsche Telekom/VoiceStream
merger. In some cases, if the shareholder actually or constructively owns
Deutsche Telekom ADSs or Deutsche Telekom ordinary shares other than those
received as a result of the Deutsche Telekom/VoiceStream merger, the recognized
gain could be treated as having the effect of the distribution of a dividend,
under the tests set forth in Section 302 of the U.S. tax code, in which case
such gain would be treated as ordinary dividend income.

     The aggregate tax basis of the Deutsche Telekom ADSs or Deutsche Telekom
ordinary shares received by a U.S. holder in the Deutsche Telekom/VoiceStream
merger (including any fractional interests to which the U.S. holder would be
entitled but for the special treatment of fractional interests described below)
will equal the aggregate tax basis of the VoiceStream common shares exchanged
for the Deutsche Telekom ADSs or Deutsche Telekom ordinary shares, increased by
the amount of gain (including any gain that is treated as a dividend) recognized
by the U.S. holder as a result of his exchange of VoiceStream common shares in
the Deutsche Telekom/VoiceStream merger, and decreased by the amount of cash
received by the U.S. holder in the Deutsche Telekom/VoiceStream merger (other
than cash received in lieu of a fractional Deutsche Telekom ADS or Deutsche
Telekom ordinary share). The holding period of the Deutsche Telekom ADSs or
Deutsche Telekom ordinary shares received will include the holding period of the
VoiceStream common shares exchanged therefor.

     Fractional interests in Deutsche Telekom ADSs or Deutsche Telekom ordinary
shares will not be issued to VoiceStream shareholders in the Deutsche
Telekom/VoiceStream merger. Instead, any fractional interests VoiceStream
shareholders otherwise would have been entitled to receive will be sold and the
proceeds will be paid to those shareholders. A U.S. holder who receives cash in
respect of a fractional interest in a Deutsche Telekom ADS or Deutsche Telekom
ordinary share will recognize gain or loss equal to the difference between the
cash received for the fractional share and the U.S. holder's tax basis in the
VoiceStream common shares exchanged which is allocable to the fractional
interest. Any such gain or loss generally will be capital gain or loss, and
generally will be long-term capital gain or loss with respect to VoiceStream
common shares held for more than 12 months at the completion of the Deutsche
Telekom/ VoiceStream merger.

     A U.S. HOLDER WHO IS A "FIVE-PERCENT TRANSFEREE SHAREHOLDER" OF DEUTSCHE
TELEKOM IMMEDIATELY AFTER THE DEUTSCHE TELEKOM/VOICESTREAM MERGER, AS DEFINED IN
TREASURY REGULATIONS PROMULGATED UNDER SECTION 367(a) OF THE U.S. TAX CODE, WILL
QUALIFY FOR NON-RECOGNITION TREATMENT AS DESCRIBED IN THIS PROXY
STATEMENT/PROSPECTUS ONLY IF THE U.S. HOLDER FILES WITH THE IRS A "GAIN
RECOGNITION AGREEMENT," AS DEFINED IN SUCH TREASURY REGULATIONS. ANY U.S. HOLDER
OF VOICESTREAM COMMON SHARES WHO MAY BE A FIVE-PERCENT TRANSFEREE SHAREHOLDER IS
URGED TO CONSULT HIS TAX ADVISOR CONCERNING THE DECISION TO FILE A GAIN
RECOGNITION AGREEMENT AND THE PROCEDURES TO BE FOLLOWED IN CONNECTION WITH THAT
FILING.
                                       112
<PAGE>   131

     U.S. Holders Whose Merger Consideration Consists Solely of Cash

     A U.S. holder of VoiceStream common shares that receives only cash in the
Deutsche Telekom/ VoiceStream merger will generally recognize gain or loss for
U.S. federal income tax purposes equal to the difference between the amount of
cash received and the U.S. holder's tax basis in the VoiceStream common shares
surrendered in the Deutsche Telekom/VoiceStream merger. Except as described in
the next sentence, such recognized gain or loss generally will be capital gain
or loss, and generally will be long term with respect to VoiceStream common
shares held by the U.S. holder for more than 12 months at the completion of the
Deutsche Telekom/VoiceStream merger. In some cases, if the shareholder actually
or constructively owns Deutsche Telekom ADSs or Deutsche Telekom ordinary
shares, the recognized gain could be treated as having the effect of the
distribution of a dividend, under the tests set forth in Section 302 of the U.S.
tax code, in which case such gain would be treated as ordinary dividend income.

     U.S. Holders who are Dissenting Sharesholders

     Subject to the discussion below, a U.S. holder who exercises his right to
dissent from the Deutsche Telekom/VoiceStream merger will recognize gain or loss
on the exchange of his VoiceStream common shares for cash in an amount equal to
the difference between the cash received (other than amounts, if any, which are
or are deemed to be interest for U.S. federal income tax purposes, which amounts
will be taxed as ordinary income) and his tax basis in his VoiceStream common
shares. Such gain or loss generally will be capital gain or loss and generally
will be long-term capital gain or loss with respect to VoiceStream shares held
for more than 12 months at the completion of the Deutsche Telekom/VoiceStream
merger. A dissenting shareholder may be required to recognize any gain or loss
in the year the Deutsche Telekom/VoiceStream merger closes, irrespective of
whether the dissenting shareholder actually receives payment for his or her
shares in that year. In some instances, cash received by a dissenting
VoiceStream shareholder could be taxed as ordinary dividend income if the
shareholder actually or constructively owns Deutsche Telekom ADSs or Deutsche
Telekom ordinary shares under the tests set forth in Section 302 of the U.S. tax
code after the Deutsche Telekom/VoiceStream merger.

     U.S. Holders of Employee Stock Options

     The exchange pursuant to the Deutsche Telekom/VoiceStream merger by a U.S.
holder of an employee stock option to acquire VoiceStream common shares for an
option to acquire Deutsche Telekom ADSs or Deutsche Telekom ordinary shares will
not be taxable for U.S. federal income tax purposes. A U.S. holder of an option
to acquire a Deutsche Telekom ADS or Deutsche Telekom ordinary share who
received that option in exchange for an option to acquire VoiceStream common
shares that was received as compensation, and who exercises that Deutsche
Telekom option, generally will recognize ordinary income for U.S. federal income
tax purposes in an amount equal to the excess of the fair market value on the
exercise date of the Deutsche Telekom ADS or Deutsche Telekom ordinary share
received pursuant to the exercise over the price paid for the Deutsche Telekom
ADS or Deutsche Telekom ordinary share pursuant to the option, and generally
will be subject to applicable withholding taxes. A U.S. holder's tax basis in
Deutsche Telekom ADSs or Deutsche Telekom ordinary shares received as a result
of the exercise of the option will equal the fair market value of the Deutsche
Telekom ADS or Deutsche Telekom ordinary share on the exercise date and a U.S.
holder's holding period will begin on the exercise date. Thereafter, the U.S.
holder will be subject to the rules discussed below with respect to U.S. holders
of Deutsche Telekom ADSs and Deutsche Telekom ordinary shares.

     The foregoing discussion does not address the U.S. federal income tax
consequences of the exercise of any option that is treated as an incentive stock
option within the meaning of Section 422(b) of the U.S. tax code. Any U.S.
holder of an option that is treated as an incentive stock option is urged to
consult his own tax advisor concerning the consequences to him of the Deutsche
Telekom/VoiceStream merger and exercise of the option.

     U.S. Backup Withholding

     Under the U.S. tax code, a U.S. holder of VoiceStream common shares may be
subject, under certain circumstances, to backup withholding at a rate of 31%
with respect to the amount of cash, if any, received in the Deutsche
Telekom/VoiceStream merger (including cash received in lieu of fractional shares
or upon exercise of dissenters' rights) unless the U.S. holder provides proof of
an applicable exemption or correct taxpayer identification number and otherwise
complies with applicable requirements of the backup withholding rules. Any
amount withheld under the backup withholding rules is not additional tax and may
be refunded or credited against the U.S. holder's federal income tax liability,
so long as the required information is furnished to the IRS.

U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE DEUTSCHE TELEKOM/POWERTEL MERGER TO
U.S. HOLDERS OF POWERTEL COMMON SHARES

     In the opinion of Morris, Manning & Martin, LLP, counsel to Powertel, and
Cleary, Gottlieb, Steen & Hamilton, counsel to Deutsche Telekom, subject to the
limitations and qualifications set forth under the heading "U.S. Federal and
German Tax Consequences -- General", the discussion in this section sets forth
the material U.S. federal income tax consequences of the Deutsche
Telekom/Powertel merger to U.S. holders of Powertel common shares.

     Tax Opinion

     The obligation of Powertel to complete the Deutsche Telekom/Powertel merger
is conditioned on the receipt of an opinion from Morris, Manning & Martin, LLP,
counsel to Powertel, and the obligation of Deutsche Telekom to complete the
Deutsche Telekom/Powertel merger is conditioned on the receipt of an opinion
from Cleary, Gottlieb, Steen & Hamilton, counsel to Deutsche Telekom, each
opinion substantially to the effect that the Deutsche Telekom/Powertel merger
will qualify as a reorganization within the meaning of Section 368(a) of the
U.S. tax code and that each transfer of property to Deutsche Telekom by a
shareholder of Powertel pursuant to the Deutsche Telekom/Powertel merger will
not be subject to Section 367(a)(1) of the U.S. tax code. Counsels' tax opinions
will be based upon assumptions noted in the opinions, including an assumption
that any "five-percent transferee shareholder" of Deutsche Telekom, as defined
in Treasury regulations promulgated under Section 367(a) of the U.S. tax code,
will file a "gain recognition agreement" as defined in such regulations, and on
factual representations of Powertel and Deutsche Telekom contained in
certificates signed by officers of Powertel and Deutsche Telekom to be delivered
at the time of the Deutsche Telekom/Powertel merger. Powertel does not intend to
waive the receipt of its counsel's opinion as a condition to its obligation to
complete the Deutsche Telekom/Powertel merger. Counsels' opinions will not be
binding on the IRS or any court.

     U.S. Holders of Powertel Common Shares

     For U.S. federal income tax purposes, assuming that the Deutsche
Telekom/Powertel merger will qualify as a reorganization within the meaning of
Section 368(a) of the U.S. tax code and that each transfer of property to
Deutsche Telekom by a shareholder of Powertel pursuant to the Deutsche
Telekom/Powertel merger will not be subject to Section 367(a)(1) of the U.S. tax
code, a U.S. holder of Powertel common shares generally will not recognize any
gain or loss upon his receipt of merger consideration in the Deutsche
Telekom/Powertel merger (except with respect to cash received in lieu of
fractional shares, as discussed further below).

     The aggregate tax basis of the Deutsche Telekom ADSs or Deutsche Telekom
ordinary shares received by a U.S. holder in the Deutsche Telekom/Powertel
merger (including any fractional interest to which the U.S. holder would be
entitled but for the special treatment of fractional interests described below)
generally will equal the aggregate tax basis of the Powertel common shares
exchanged for the Deutsche Telekom ADSs or Deutsche Telekom ordinary shares. The
holding period of the Deutsche Telekom ADSs or Deutsche Telekom ordinary shares
received will include the holding period of the Powertel common shares exchanged
therefor.

                                       114
<PAGE>   133

     Fractional interests in Deutsche Telekom ADSs or Deutsche Telekom ordinary
shares will not be issued to Powertel shareholders in the Deutsche
Telekom/Powertel merger. Instead, any fractional interests in Deutsche Telekom
ADSs or Deutsche Telekom ordinary shares that a U.S. holder of Powertel common
shares otherwise would have been entitled to receive will be sold and the
proceeds will be paid to those shareholders. A U.S. holder who receives cash in
respect of a fractional interest in a Deutsche Telekom ADS or Deutsche Telekom
ordinary share will recognize gain or loss equal to the difference between the
cash received for the fractional share and the U.S. holder's tax basis in the
Powertel common shares exchanged which is allocable to the fractional interest.
Any such gain or loss generally will be capital gain or loss, and generally will
be long-term capital gain or loss with respect to Powertel common shares held
for more than 12 months at the completion of the Deutsche Telekom/Powertel
merger.

     A U.S. HOLDER WHO IS A "FIVE-PERCENT TRANSFEREE SHAREHOLDER" OF DEUTSCHE
TELEKOM AFTER THE DEUTSCHE TELEKOM/POWERTEL MERGER, AS DEFINED IN TREASURY
REGULATIONS PROMULGATED UNDER SECTION 367(a) OF THE U.S. TAX CODE, WILL QUALIFY
FOR NON-RECOGNITION TREATMENT AS DESCRIBED IN THIS PROXY STATEMENT/PROSPECTUS
ONLY IF THE SHAREHOLDER FILES WITH THE IRS A "GAIN RECOGNITION AGREEMENT," AS
DEFINED IN SUCH TREASURY REGULATIONS. ALTHOUGH NO SUCH PERSONS ARE EXPECTED TO
EXIST SOLELY AS A RESULT OF THE DEUTSCHE TELEKOM/POWERTEL MERGER, ANY U.S.
HOLDER OF POWERTEL SHARES WHO IS CONCERNED THAT HE MAY BE A FIVE-PERCENT
TRANSFEREE SHAREHOLDER IS URGED TO CONSULT HIS TAX ADVISOR CONCERNING THE
DECISION TO FILE A GAIN RECOGNITION AGREEMENT AND THE PROCEDURES TO BE FOLLOWED
IN CONNECTION WITH THAT FILING.

     U.S. Holders of Employee Stock Options

     The exchange pursuant to the Deutsche Telekom/Powertel merger by a U.S.
holder of an employee stock option to acquire Powertel common shares for an
option to acquire Deutsche Telekom ADSs or Deutsche Telekom ordinary shares will
not be taxable for U.S. federal income tax purposes. A U.S. holder of an option
to acquire a Deutsche Telekom ADS or Deutsche Telekom ordinary share who
received that option in exchange for an option to acquire Powertel common shares
that was received as compensation, and who exercises that Deutsche Telekom
option, generally will recognize ordinary income for U.S. federal income tax
purposes in an amount equal to the excess of the fair market value on the
exercise date of the Deutsche Telekom ADS or Deutsche Telekom ordinary share
received pursuant to the exercise over the price paid for the Deutsche Telekom
ADS or Deutsche Telekom ordinary share pursuant to the option, and generally
will be subject to applicable withholding taxes. A U.S. holder's tax basis in
Deutsche Telekom ADSs or Deutsche Telekom ordinary shares received as a result
of the exercise of the option will equal the fair market value of the shares on
the exercise date and a U.S. holder's holding period will begin on the exercise
date. Thereafter, the U.S. holder will be subject to the rules discussed below
with respect to U.S. holders of Deutsche Telekom ADSs and Deutsche Telekom
ordinary shares.

     The foregoing discussion does not address the U.S. federal income tax
consequences of the exercise of any option that is treated as an incentive stock
option within the meaning of Section 422(b) of the U.S. tax code. Any U.S.
holder of an option that is treated as an incentive stock option is urged to
consult his own tax advisor concerning the consequences to him of the Deutsche
Telekom/Powertel merger and exercise of the option.

     U.S. Backup Withholding

     Under the U.S. tax code, a U.S. holder of Powertel common shares may be
subject, under certain circumstances, to backup withholding at a rate of 31%
with respect to the amount of cash, if any, received in the Deutsche
Telekom/Powertel merger (including cash received in lieu of fractional shares)
unless the U.S. holder provides proof of an applicable exemption or correct
taxpayer identification number and otherwise complies with applicable
requirements of the backup withholding rules. Any amount withheld under the
backup withholding rules is not additional tax and may be refunded or credited
against the U.S. holder's federal income tax liability, so long as the required
information is furnished to the IRS.

U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE VOICESTREAM/POWERTEL MERGER TO U.S.
HOLDERS OF POWERTEL COMMON SHARES

     In the opinion of Morris, Manning & Martin, LLP, counsel to Powertel,
Jones, Day, Reavis & Pogue, tax counsel to VoiceStream, and Preston, Gates &
Ellis LLP, counsel to VoiceStream, subject to the limitations and qualifications
set forth under the heading "U.S. Federal and German Tax Consequences --
General", the discussion in this section sets forth the material U.S. federal
income tax consequences of the VoiceStream/Powertel merger to U.S. holders of
Powertel common shares.

     Tax Opinion

     The obligation of Powertel to complete the VoiceStream/Powertel merger is
conditioned on the receipt of an opinion from Morris, Manning & Martin, LLP,
counsel to Powertel, and the obligation of VoiceStream to complete the
VoiceStream/Powertel merger is conditioned on the receipt of an opinion from
Preston, Gates & Ellis LLP, counsel to VoiceStream and/or Jones, Day Reavis &
Pogue, tax counsel to VoiceStream, each opinion substantially to the effect that
the VoiceStream/Powertel merger will qualify as a reorganization within the
meaning of Section 368(a) of the U.S. tax code. Counsels' tax opinions will be
based upon assumptions noted in the opinions and on factual representations of
Powertel and VoiceStream contained in certificates signed by officers of
Powertel and VoiceStream to be delivered at the time of the VoiceStream/Powertel
merger. Powertel does not intend to waive the receipt of its counsel's opinion
as a condition to its obligation to complete the VoiceStream/Powertel merger.
Counsels' opinions will not be binding on the IRS or any court.

     U.S. Holders of Powertel Common Shares

     For U.S. federal income tax purposes, assuming that the
VoiceStream/Powertel merger will qualify as a reorganization within the meaning
of Section 368(a) of the U.S. tax code, a U.S. holder of Powertel common shares
generally will not recognize any gain or loss upon his receipt of merger
consideration in the VoiceStream/Powertel merger (except with respect to cash
received in lieu of fractional shares, as discussed further below).

     The aggregate tax basis of the VoiceStream common shares received by a U.S.
holder in the VoiceStream/Powertel merger (including any fractional interests to
which the U.S. holder would be entitled but for the special treatment of
fractional interests discussed below) generally will equal the aggregate tax
basis of the Powertel common shares exchanged therefor. The holding period of
the VoiceStream common shares received will include the holding period of the
Powertel common shares exchanged therefor. The tax basis of VoiceStream common
shares received with respect to unpaid dividends will be their fair market value
on, and their holding period will begin on the day following, the date of the
VoiceStream/Powertel merger.

     Fractional interests in VoiceStream common shares will not be issued to
Powertel shareholders in the VoiceStream/Powertel merger. Instead, cash will be
paid in lieu of any fractional interests in VoiceStream common shares that a
U.S. holder of Powertel common shares otherwise would have been entitled to
receive. A U.S. holder who receives cash in lieu of a fractional share of
VoiceStream common share will recognize gain or loss equal to the difference
between the cash received for the fractional share and the U.S. holder's tax
basis in the Powertel common shares exchanged which is allocable to the
fractional interest. Any such gain or loss generally will be capital gain or
loss, and generally will be long-term capital gain or loss with respect to
Powertel common shares held for more than 12 months at the completion of the
VoiceStream/Powertel merger.

     U.S. Holders of Employee Stock Options

     The exchange pursuant to the VoiceStream/Powertel merger by a U.S. holder
of an employee stock option to acquire Powertel common shares for an option to
acquire VoiceStream common shares will not be taxable for U.S. federal income
tax purposes. A U.S. holder of an option to acquire VoiceStream common shares
who received that option in exchange for an option to acquire Powertel common
shares
                                       116
<PAGE>   135

that was received as compensation, and who exercises that VoiceStream option,
generally will recognize ordinary income for U.S. federal income tax purposes in
an amount equal to the excess of the fair market value on the exercise date of
the VoiceStream common shares received pursuant to the exercise over the price
paid for the VoiceStream common shares pursuant to the option, and generally
will be subject to applicable withholding taxes. A U.S. holder's tax basis in
VoiceStream common shares received as a result of the exercise of the option
will equal the fair market value of the shares on the exercise date and a U.S.
holder's holding period will begin on the exercise date.

     The foregoing discussion does not address the U.S. federal income tax
consequences of the exercise of any option that is treated as an incentive stock
option within the meaning of Section 422(b) of the U.S. tax code. Any U.S.
holder of an option that is treated as an incentive stock option is urged to
consult his own tax advisor concerning the consequences to him of the
VoiceStream/Powertel merger and exercise of the option.

     U.S. Backup Withholding

     Under the U.S. tax code, a U.S. holder of Powertel common shares may be
subject, under certain circumstances, to backup withholding at a rate of 31%
with respect to the amount of cash, if any, received in the VoiceStream/Powertel
merger (including cash received in lieu of fractional shares) unless the U.S.
holder provides proof of an applicable exemption or correct taxpayer
identification number and otherwise complies with applicable requirements of the
backup withholding rules. Any amount withheld under the backup withholding rules
is not additional tax and may be refunded or credited against the U.S. holder's
federal income tax liability, so long as the required information is furnished
to the IRS.

U.S. FEDERAL INCOME TAX AND GERMAN TAX CONSIDERATIONS FOR U.S. RESIDENT HOLDERS
OF DEUTSCHE TELEKOM ADSS AND DEUTSCHE TELEKOM ORDINARY SHARES

     The following is a summary of the material U.S. federal income tax and
German tax considerations related to the acquisition, ownership and disposition
of Deutsche Telekom ADSs or Deutsche Telekom ordinary shares by a holder that is
a resident of the United States for purposes of the income tax convention
between the United States and Germany (the "Income Tax Treaty") and is fully
eligible for benefits under the Income Tax Treaty (a "U.S. resident holder").
The summary does not purport to be a comprehensive description of all of the tax
considerations that may be relevant to any particular investor, including tax
considerations, that arise from rules of general application or that are
generally assumed to be known by investors. In particular, the summary does not
deal with U.S. resident holders that do not hold Deutsche Telekom ADSs or
Deutsche Telekom ordinary shares as capital assets. The summary does not address
the tax treatment of holders that are subject to special rules, such as banks,
insurance companies, dealers in securities or currencies, persons holding
property as part of an integrated investment (including a "straddle") that
includes one or more other positions, persons that own, directly or indirectly,
10% or more of Deutsche Telekom's voting shares and holders whose "functional
currency" is not the U.S. dollar. The summary is based on laws, treaties and
regulatory interpretations in effect on the date hereof, all of which are
subject to change.

     Holders should consult their own advisors regarding the tax consequences of
the acquisition, ownership and disposition of Deutsche Telekom ADSs or Deutsche
Telekom ordinary shares in light of their particular circumstances, including
the effect of any state, local, or other national laws.

     The beneficial owner of a Deutsche Telekom ADS or Deutsche Telekom ordinary
share generally will be entitled to Income Tax Treaty benefits, and therefore
will be a U.S. resident holder, if it is (1) an individual resident of the
United States, a U.S. corporation, or a partnership, estate or trust to the
extent its income from whatever source derived is subject to taxation in the
United States in its hands or in the hands of its partners or beneficiaries; (2)
not also a resident of Germany for German tax purposes; and (3) not subject to
an anti-treaty shopping article that applies in limited circumstances. The
Income Tax Treaty benefits discussed below generally are not available to U.S.
taxpayers that hold Deutsche Telekom ADSs or Deutsche Telekom ordinary shares in
connection with the conduct of business through a

                                       117
<PAGE>   136

permanent establishment, or the performance of personal services through a fixed
base, in Germany. This summary does not discuss the treatment of such holders.

     In general, for U.S. federal income tax purposes and for purposes of the
Income Tax Treaty, beneficial owners of Deutsche Telekom ADSs will be treated as
the beneficial owners of the Deutsche Telekom ordinary shares represented by
those Deutsche Telekom ADSs.

     Dividends

     As described more fully below, dividends paid by German corporations
generally are subject to German withholding tax at an aggregate rate of 26.375%
(consisting of a 25% withholding tax and a 1.375% surcharge).

     Under the Income Tax Treaty, the German withholding tax rate is reduced to
15% of the declared dividend. During the period in which the existing corporate
tax imputation system continues to apply to individuals under German law, U.S.
resident holders are entitled to claim an additional reduction in German
withholding tax equal to 5% of the gross dividend. Accordingly, a U.S. resident
holder would be entitled to receive a refund payment from the German tax
authorities equal to 16.375% of the declared dividend. The Income Tax Treaty
provides that a portion of this payment (i.e., 11.375% of the declared dividend)
will be treated for U.S. tax purposes as a reduction in German withholding tax
to the generally applicable Income Tax Treaty rate of 15%, and the remainder of
the payment (i.e., 5% of the declared dividend) will be treated as the net
amount of an additional dividend of 5.88% of the declared dividend that has been
subject to a 15% German withholding tax.

     Thus, if Deutsche Telekom declares a dividend of 100, a U.S. resident
holder initially will receive 73.625 (100 minus the 26.375% withholding tax).
The U.S. resident holder then can claim a refund from the German authorities of
16.375 and thereby will receive total cash payment of 90 (i.e., 90% of the
declared dividend). For U.S. tax purposes, the holder will be deemed to have
received gross dividends of 105.88, consisting of the declared dividend of 100,
plus the deemed additional dividend of 5.88 that is associated with the Income
Tax Treaty refund.

     As discussed below under "German Tax Considerations for Non-German Holders
of Deutsche Telekom ADSs and Deutsche Telekom Ordinary Shares -- Dividends,"
pursuant to the Tax Reduction Act adopted by the German Parliament on July 14,
2000, the German corporate tax imputation system will be abolished. Under the
Income Tax Treaty, a U.S. resident holder will still be entitled to a reduction
in the German withholding tax rate to 15%. For a declared dividend of 100, a
U.S. resident holder would initially receive 78.9 and could claim a refund from
the German tax authorities of 6.1 and would therefore receive a total cash
payment of 85. For U.S. federal income tax purposes, a U.S. resident holder
would be deemed to have received gross dividends of 100.

     As discussed below under "German Tax Considerations for Non-German Holders
of Deutsche Telekom ADSs and Deutsche Telekom Ordinary Shares -- Dividends," the
Tax Reduction Act will, in principle, enter into force on January 1, 2001.
However, transition rules exist under which certain changes will only become
effective in 2002. Dividends paid in 2001 out of earnings that accrued prior to
the end of the year 2000 will still be subject to the corporate tax imputation
system.

     The gross amount of dividends received by a U.S. resident holder (including
the additional dividend associated with the Income Tax Treaty refund and amounts
withheld in respect of German withholding tax) generally will be subject to U.S.
federal income taxation as foreign source dividend income, and will not be
eligible for the dividends received deduction generally allowed to U.S.
corporations. German withholding tax at the 15% rate provided under the Income
Tax Treaty will be treated as a foreign income tax that, subject to generally
applicable limitations under U.S. tax law, is eligible for credit against a U.S.
resident holder's U.S. federal income tax liability or, at the holder's
election, may be deducted in computing taxable income. Thus, for a declared
dividend of 100, under the current German corporate tax imputation system, a
U.S. resident holder would be deemed to have paid German taxes of 15.88, but
under the Tax Reduction Act, a U.S. resident holder would be deemed to have paid
German taxes of 15. For foreign tax credit purposes, dividends paid by Deutsche
Telekom will be foreign source "passive

                                       118
<PAGE>   137

income" or, in the case of certain U.S. resident holders, "financial services
income". Foreign tax credits will not be allowed for withholding taxes imposed
in respect of certain short-term or hedged positions in Deutsche Telekom ADSs or
Deutsche Telekom ordinary shares or in respect of arrangements in which a U.S.
resident holder's expected economic profit, after non-U.S. taxes, is
insubstantial. U.S. resident holders should consult their own tax advisors
concerning the implications of these rules in light of their particular
circumstances.

     Dividends paid in non-U.S. currency will be included in the income of a
U.S. resident holder in a U.S. dollar amount calculated by reference to the
exchange rate in effect on the date of receipt by the holder or, in the case of
Deutsche Telekom ADSs, by the depositary bank for the ADSs (the "Depositary"),
regardless of whether the payment is in fact converted into U.S. dollars. If
dividends paid in foreign currency are converted into U.S. dollars on the date
of receipt, U.S. resident holders generally should not be required to recognize
foreign currency gain or loss in respect of the dividend income. A U.S. resident
holder may be required to recognize domestic-source foreign currency gain or
loss on the receipt of a refund in respect of German withholding tax (but not
with respect to the portion of the Income Tax Treaty refund that is treated as
an additional dividend) to the extent the U.S. dollar value of the refund
differs from the U.S. dollar equivalent of that amount on the date of receipt of
the underlying dividend.

     Refund Procedures

     Pursuant to administrative procedures introduced on a trial basis, claims
for refunds payable under the Income Tax Treaty to U.S. resident holders must be
submitted to the German tax authorities by the Depositary collectively on behalf
of all such U.S. resident holders. However, this procedure is not available for
U.S. resident holders entitled to refunds in excess of DM 300 for the calendar
year; such holders must file separate claims. Claims must be filed within four
years of the end of the calendar year in which the dividend was received.

     Details of the collective refund procedure are available from the
Depositary. Individual claims for refund are made on a special German form,
which must be filed with the German tax authorities: Bundesamt fur Finanzen,
Friedhofstrasse 1, 53221 Bonn, Germany. Copies of the required form may be
obtained from the German tax authorities at the same address or from the Embassy
of the Federal Republic of Germany, 4645 Reservoir Road, N.W., Washington, D.C.
20007-1998.

     As part of the individual refund claim, a U.S. resident holder must submit
to the German tax authorities the original bank voucher (or certified copy
thereof) issued by the paying entity documenting the tax withheld, and an
official certification on IRS Form 6166 of its last filed U.S. federal income
tax return. IRS Form 6166 may be obtained by filing a request with the Internal
Revenue Service Center in Philadelphia, Pennsylvania, Foreign Certificate
Request, P.O. Box 16347, Philadelphia, PA 19114-0447. Requests for certification
must include the holder's name, Social Security number or Employer
Identification number, tax return form number, and tax period for which the
certification is requested. Requests for certification can include a request to
the IRS to send the certification directly to the German tax authorities. If no
such request is made, the IRS will send a certificate on IRS Form 6166 to the
U.S. resident holder, which then must submit the certification with its claim
for refund.

     Refunds under the Income Tax Treaty are not available in respect of
Deutsche Telekom ADSs or Deutsche Telekom ordinary shares held in connection
with a permanent establishment or fixed base in Germany.

     Capital Gains

     Under the Income Tax Treaty, a U.S. resident holder will not be subject to
German capital gains tax in respect of a sale or other disposition of Deutsche
Telekom ADSs or Deutsche Telekom ordinary shares unless the Deutsche Telekom
ADSs or Deutsche Telekom ordinary shares were held in connection with a
permanent establishment or fixed base in Germany.

     Gain or loss realized by a U.S. resident holder on the sale or disposition
of Deutsche Telekom ADSs or Deutsche Telekom ordinary shares will be capital
gain or loss, and will be long-term gain or loss if the

                                       119
<PAGE>   138

Deutsche Telekom ADSs or Deutsche Telekom ordinary shares were held for more
than one year. The net amount of long-term capital gain realized by an
individual holder generally is subject to taxation at a present maximum rate of
20%. A U.S. resident holder's ability to offset capital losses against ordinary
income is subject to limitations. Deposits and withdrawals of shares in exchange
for Deutsche Telekom ADSs will not result in the realization of gain or loss for
U.S. federal income tax purposes.

     Inheritance and Gift Tax

     Under the current estate, inheritance and gift tax treaty between the
United States and Germany (the "Estate Tax Treaty"), a transfer of Deutsche
Telekom ADSs or Deutsche Telekom ordinary shares by gift or by reason of the
death of a U.S. resident holder generally will not be subject to German gift or
inheritance tax unless the donor or transferor, or the heir, donee or other
beneficiary, is domiciled in Germany for purposes of the Estate Tax Treaty at
the time gift was made, or at the time of the donor's or transferors' death, or
the Deutsche Telekom ADSs or Deutsche Telekom ordinary shares were held in
connection with a permanent establishment or fixed base in Germany.

     The Estate Tax Treaty provides a credit against U.S. federal estate and
gift tax liability for the amount of inheritance and gift tax paid in Germany,
subject to certain limitations, in a case where Deutsche Telekom ADSs or
Deutsche Telekom ordinary shares are subject to German inheritance or gift tax
and U.S. federal estate or gift tax.

     Information Reporting and Backup Withholding

     Dividends on Deutsche Telekom ADSs or Deutsche Telekom ordinary shares, and
payments of the proceeds of a sale of Deutsche Telekom ADSs or Deutsche Telekom
ordinary shares paid within the United States or through certain U.S.-related
financial intermediaries are subject to information reporting and may be subject
to backup withholding at a 31% rate unless the holder (1) is a corporation or
other exempt recipient or (2) provides a taxpayer identification number and
certifies that no loss of exemption from backup withholding has occurred.
Holders that are not United States persons generally are not subject to
information reporting or backup withholding. However, such a holder may be
required to provide a certification to establish its non-U.S. status in
connection with payments received within the United States or through certain
U.S.-related financial intermediaries.

GERMAN TAX CONSIDERATIONS FOR NON-GERMAN HOLDERS OF DEUTSCHE TELEKOM ADSS AND
DEUTSCHE TELEKOM ORDINARY SHARES

     The following is a brief summary of material German tax considerations for
beneficial owners of Deutsche Telekom ADSs or Deutsche Telekom ordinary shares
that are not German residents for German income tax purposes and do not hold
Deutsche Telekom ADSs or Deutsche Telekom ordinary shares as part of a permanent
establishment or a fixed base in Germany ("Non-German Holders"). This summary is
based upon German law and typical tax and other treaties between Germany and
other countries in effect as of the date hereof and is subject to changes in
German law or in such treaties. The following is not meant to be a comprehensive
discussion of all of the German tax consequences which may be relevant for
Non-German Holders. Prospective holders of Deutsche Telekom ADSs or Deutsche
Telekom ordinary shares should consult their tax advisors regarding the German
federal, state and local tax consequences of the acquisition, ownership and
disposition of Deutsche Telekom ADSs or Deutsche Telekom ordinary shares in
light of their particular circumstances.

     The following discussion does not purport to be a comprehensive discussion
of all German tax consequences which may be relevant for Non-German Holders.

     Company Taxation in Germany

     In general, German corporations are subject to trade tax on income and to
corporate income tax at a rate of 40% on non-distributed profits and of 30% on
distributed profits. Since January 1, 1998, the corporate income tax liability
has been subject to a 5.5% solidarity surcharge (Solidaritatszuschlag). This
currently results in an effective aggregate corporate income tax charge of
31.94% on distributed profits.

                                       120
<PAGE>   139

German resident taxpayers (including foreign investors that hold shares or ADSs
as part of a permanent establishment or a fixed base in Germany) are entitled to
a refundable tax credit in the amount of three-sevenths of the gross amount
(before dividend withholding tax) of profits distributed, which credit also
reduces the basis for the 5.5% surcharge on the German taxpayer's income tax
liability. That credit or refund is not available to Non-German Holders.

     In addition, German corporations are subject to a profit-related trade tax,
the exact amount of which depends on the municipality in which the corporation
maintains its business establishments. Trade tax is a deductible item in
computing the corporation's tax base for the corporate income tax purposes.

     Taxation of Dividends

     A 25% withholding tax (plus a solidarity surcharge of 5.5 percent thereon
resulting in withholding tax burden of 26.375) is imposed on gross dividend
distributions by a German corporation. With respect to a Non-German Holder, this
rate may be reduced by a tax treaty applicable to such Non-German Holder. Under
most tax treaties the withholding tax rate is reduced to 15%. The reduction is
granted by way of a refund of the difference between the tax withheld at the
statutory rate of 25% plus the surcharge and the applicable treaty rate upon
application to the German tax authorities (Bundesamt fur Finanzen,
Friedhofstrasse 1, 53225 Bonn, Germany). For Non-German Holders of ADSs entitled
to the benefits of the Income Tax Treaty a special refund procedure may apply,
as described above under the heading "U.S. Federal Income Tax and German Tax
Considerations for U.S. Resident Holders".

     Under the Income Tax Treaty, during the period in which the corporate tax
imputation system continues to apply to individuals under German law, qualifying
U.S. shareholders are entitled to an additional reduction in German tax equal to
5% of the gross amount of the dividend, which is refundable together with the
general treaty refund discussed in the preceding paragraph. Special U.S. tax
rules applicable to this additional refund are discussed above under "U.S.
Federal Income Tax and German Tax Considerations for U.S. Resident Holders of
Deutsche Telekom ADSs and Deutsche Telekom Ordinary Shares -- Refund
Procedures".

     On July 14, 2000, the German parliament adopted a Tax Reduction Act
(Steuersenkungsgesetz) which, in principle, will enter into force on January 1,
2001. However, transition rules exist under which certain changes will only
become effective in 2002. Pursuant to the Tax Reduction Act, the corporate tax
imputation system will be abolished and the withholding tax and corporate income
tax rates will be reduced effective January 1, 2001. Corporate profits will be
subject to tax separately at corporate and shareholder levels. The corporate
income tax rate will be 25% (plus solidarity surcharge of 1.375%) on distributed
and retained earnings. Dividends received by Non-German Holders will be subject
to withholding tax at a rate of 20% (plus a 5.5% solidarity surcharge resulting
in an effective rate of 21.1%). The withholding tax rate for Non-German Holders
may be lower under the provisions of an applicable double tax treaty. The
abolishment of the corporate income tax imputation system will result in U.S.
resident holders being subject to a maximum dividend withholding rate of 15%
under the Income Tax Treaty, without further reduction. Dividends paid in 2001
out of earnings that accrued prior to the end of the year will still be subject
to the imputation system.

     Capital Gains

     Under German domestic tax law, gain which Non-German Holders derive from
the sale or other disposition of Deutsche Telekom ADSs or Deutsche Telekom
ordinary shares is not subject to tax in Germany, provided the Non-German Holder
has not held, directly or indirectly, 10% or more of the shares at any time
during the 5-year period immediately preceding the disposition. Effective
January 1, 2002, this participation threshold will be reduced to 1% pursuant to
the Tax Reduction Act mentioned above. Most tax treaties concluded by Germany
with other countries (including the Income Tax Treaty) provide that Non-German
Holders resident in the respective treaty state are not subject to German income
tax on such capital gains.

                                       121
<PAGE>   140

     Inheritance and Gift Tax

     Under German law, German gift or inheritance tax will be imposed on
transfers of shares or ADSs by gift or at death of a Non-German Holder only if
(1) the donor or transferor, or the heir, donee or other beneficiary, was
domiciled in Germany at the time of the transfer or, with respect to German
citizens who are not domiciled in Germany, if such donor, transferor or
beneficiary has not been continuously outside of Germany for a period of more
than five years or had a residence in Germany during such absence, or (2) the
Deutsche Telekom ADSs or Deutsche Telekom ordinary shares subject to such
transfer consist or form part of a portfolio of 10% or more of such Deutsche
Telekom ADSs or Deutsche Telekom ordinary shares held directly or indirectly by
the donor or transferor himself or together with one or more related persons.
The few German estate tax treaties currently in force (e.g., the Estate Tax
Treaty) usually provide that German gift or inheritance tax may only be imposed
if condition (1) above is met or if the ordinary shares or ADSs were held in
connection with a permanent establishment or fixed base in Germany.

     Other Taxes

     No German transfer, stamp or other similar taxes apply to the acquisition,
sale or other disposition of Deutsche Telekom ADSs or Deutsche Telekom ordinary
shares by Non-German Holders.

                  SUMMARY OF THE DEUTSCHE TELEKOM/VOICESTREAM
                             TRANSACTION DOCUMENTS

THE DEUTSCHE TELEKOM/VOICESTREAM MERGER AGREEMENT

     This section of the proxy statement/prospectus is a summary of the
principal provisions of the Deutsche Telekom/VoiceStream merger agreement. This
summary does not purport to be complete and is qualified in its entirety by
reference to the Deutsche Telekom/VoiceStream merger agreement, a copy of which
is incorporated by reference and attached as Annex A to this proxy
statement/prospectus. VoiceStream stockholders are urged to read the Deutsche
Telekom/VoiceStream merger agreement in its entirety, as it is the legal
document governing the Deutsche Telekom/VoiceStream merger.

     The Deutsche Telekom/VoiceStream Merger

     A Delaware corporation formed by Deutsche Telekom will merge with and into
VoiceStream and, as a result, VoiceStream will become a wholly-owned subsidiary
of Deutsche Telekom.

     Effective Time and Timing of Closing

     The Deutsche Telekom/VoiceStream merger will be completed and become
effective when VoiceStream files a certificate of merger with the Secretary of
State of the State of Delaware or at such later time as is specified in the
certificate of merger in accordance with Delaware law. We expect the Deutsche
Telekom/VoiceStream merger to become effective on the same day as the closing of
the Deutsche Telekom/VoiceStream merger, which will take place on the fifth
business day (or on such other date that Deutsche Telekom and VoiceStream may
agree) after the conditions to the Deutsche Telekom/VoiceStream merger have been
satisfied or waived. In addition, on the closing date of the Deutsche
Telekom/VoiceStream merger or as soon as possible after the closing date,
Deutsche Telekom and VoiceStream will undertake a number of additional actions,
including making filings with regulatory and stock exchange authorities,
necessary to permit the issuance of the Deutsche Telekom/VoiceStream merger
consideration under German laws and regulations and the rules of the Frankfurt
Stock Exchange.

     Consideration to be Received in the Deutsche Telekom/VoiceStream Merger

     In the Deutsche Telekom/VoiceStream merger, VoiceStream stockholders will
have the right to make one of the following elections and receive the
consideration indicated below, subject to proration and adjustment described
below, for each of their VoiceStream common shares:

<TABLE>
<CAPTION>
TYPE OF ELECTION                               CONSIDERATION TO BE RECEIVED PER VOICESTREAM COMMON SHARE
----------------                               ---------------------------------------------------------
<S>                                            <C>
- Mixed......................................  $30 in cash and 3.2 Deutsche Telekom shares
- All Stock..................................  3.7647 Deutsche Telekom shares
- All Cash...................................  $200 in cash
</TABLE>

     VoiceStream stockholders who fail to make an election will be deemed to
have made a mixed cash and stock election.

     You will receive Deutsche Telekom shares in the form of Deutsche Telekom
ADSs, which are traded on the NYSE under the symbol "DT", or, if you prefer, in
the form of Deutsche Telekom ordinary shares, which trade principally on the
Frankfurt Stock Exchange under the symbol "DTE".

     Proration.  The total number of Deutsche Telekom shares that will be issued
and the total amount of cash that will be paid in the Deutsche
Telekom/VoiceStream merger is 3.2 and $30, respectively, times the total number
of VoiceStream common shares outstanding immediately prior to the completion of
the Deutsche Telekom/VoiceStream merger. Therefore, the all-stock and all-cash
elections are subject to proration to preserve these limitations on the amount
of cash to be paid and Deutsche Telecom shares to be issued.

                                       123
<PAGE>   142

     As a result, even if you elect to receive the all-stock or all-cash
consideration, you may nevertheless receive a mix of Deutsche Telekom shares and
cash. VoiceStream stockholders who make the mixed election will not be subject
to proration.

     We illustrate below how the proration mechanism will be used. For ease of
reference, we refer to the number of Deutsche Telekom shares derived by
multiplying 3.2 and the number of VoiceStream common shares outstanding
immediately prior to the completion of the Deutsche Telekom/VoiceStream merger
as the "Deutsche Telekom share issuance number." Similarly, we refer to the
amount of cash derived by multiplying $30 and the number of VoiceStream common
shares outstanding immediately prior to the completion of the Deutsche
Telekom/VoiceStream merger as the "aggregate cash amount."

     Proration if Too Much Cash is Elected.  If the all-cash election is
oversubscribed so that the amount of cash issuable in the Deutsche
Telekom/VoiceStream merger exceeds the aggregate cash amount, then VoiceStream
stockholders making an all-cash election will receive a combination of cash and
Deutsche Telekom shares calculated in the following way:

     - Step 1. Derive the available cash election amount:  the available cash
       election amount is the aggregate cash amount less the amount of cash to
       be paid in respect of shares as to which a valid mixed election is made.

     - Step 2. Derive the cash election amount:  the cash election amount is the
       product of $200 and the number of VoiceStream common shares as to which a
       valid all-cash election is made.

     - Step 3. Derive the cash proration factor:  the cash proration factor
       equals the available cash election amount divided by the cash election
       amount.

     - Step 4. Derive the prorated cash consideration:  each VoiceStream common
       share as to which a valid all-cash election is made will be converted
       into the right to receive an amount in cash equal to the product of $200
       multiplied by the cash proration factor.

     - Step 5. Derive the stock consideration:  each VoiceStream common share as
       to which a valid all-cash election is made will be converted into the
       right to receive a number of Deutsche Telekom ordinary shares equal to
       the product of (1) 3.7647 and (2) a number equal to one minus the cash
       proration factor.

     Example.  If the all-cash election of VoiceStream stockholders is
oversubscribed, we would calculate the cash proration factor as illustrated
above. Assuming that the cash proration factor is 0.6, then if you own 100
VoiceStream common shares and make an all-cash election, you would receive:

     - the amount of cash equal to 0.6 multiplied by $200, multiplied by the
       number of VoiceStream common shares you hold, or 100, for a total of
       $12,000 in cash; and

     - the number of Deutsche Telekom shares equal to 3.7647 multiplied by 0.4,
       multiplied by the number of VoiceStream common shares you hold, or 100,
       for a total of 150 Deutsche Telekom shares (plus cash for .588 of a
       Deutsche Telekom share).

     Proration if Too Many Deutsche Telekom Shares are Elected.  If the
all-stock election is oversubscribed so that the number of Deutsche Telekom
shares issuable in the Deutsche Telekom/VoiceStream merger exceeds the Deutsche
Telekom share issuance number, then VoiceStream stockholders making an all-stock
election will receive a combination of cash and Deutsche Telekom shares
calculated in the following way:

     - Step 1. Derive the available cash election amount:  the available cash
       election amount is the aggregate cash amount less the amount of cash to
       be paid in respect of shares as to which a valid mixed election is made.

     - Step 2. Derive the cash election amount:  the cash election amount is the
       product of $200 and the number of VoiceStream common shares as to which a
       valid all-cash election is made.

                                       124
<PAGE>   143

     - Step 3. Derive the excess cash amount:  the excess cash amount is the
       difference between the available cash election amount and the cash
       election amount.

     - Step 4. Derive the prorated cash consideration:  each VoiceStream common
       share as to which a valid all-stock election is made will receive an
       amount in cash equal to the excess cash amount divided by the number of
       VoiceStream common shares as to which a valid all-stock election is made.

     - Step 5. Derive the stock proration factor:  the stock proration factor is
       a fraction (1) the numerator of which is $200 minus the per share cash
       consideration calculated in Step 4 and (2) the denominator of which is
       $200.

     - Step 6. Derive the prorated stock consideration:  each VoiceStream common
       share as to which a valid all-stock election is made will be converted
       into the right to receive a number of Deutsche Telekom ordinary shares
       equal to the product of (1) 3.7647 and (2) the stock proration factor.

     Example.  If the all-stock election of VoiceStream stockholders is
oversubscribed, we would calculate the cash consideration as illustrated above.
Assuming that the prorated cash consideration is $50 per share, then the stock
proration factor would be 0.75. If you own 100 VoiceStream shares and make an
all-stock election under these circumstances, you would receive:

     - $50 multiplied by the number of VoiceStream shares you hold, or 100, for
       a total of $5,000; and

     - the amount of Deutsche Telekom ordinary shares equal to 3.7647 multiplied
       by 0.75, multiplied by the number of VoiceStream common shares you hold,
       or 100, for a total of 282 Deutsche Telekom shares (plus cash for .353 of
       a Deutsche Telekom share).

     Adjustments.  In order to preserve the tax-free treatment of the receipt of
Deutsche Telekom shares by VoiceStream stockholders for U.S. federal income tax
purposes and permit the delivery of the requisite tax opinion pursuant to the
Deutsche Telekom/VoiceStream merger agreement, the aggregate cash consideration
paid to all VoiceStream stockholders (plus approximately $625 million of
Deutsche Telekom's investment in VoiceStream voting preferred shares) cannot
exceed 20% of the total value of the shares and cash delivered by Deutsche
Telekom to VoiceStream's stockholders. VoiceStream stockholders would
potentially be subject to this adjustment regardless of the type of election
(all-stock, all-cash or mixed) they have made. This adjustment could occur if
the trading price of the Deutsche Telekom shares at the time of the Deutsche
Telekom/VoiceStream merger is lower than ____euros (or, $____, when translated
into U.S. dollars), but could occur at a higher price depending on a number of
other factors, including the exchange rate between the euro and the U.S. dollar
immediately before the closing of the Deutsche Telekom/VoiceStream merger, the
number of outstanding VoiceStream shares at the time of the Deutsche
Telekom/VoiceStream merger and the number of VoiceStream stockholders who
exercise dissenters' rights. Accordingly, depending on the value of Deutsche
Telekom shares at the time the Deutsche Telekom/VoiceStream merger is completed,
the cash portion of the Deutsche Telekom/VoiceStream merger consideration may be
reduced, with the value of the reduction to be made up by an increased number of
Deutsche Telekom shares based on a calculated average price of the Deutsche
Telekom shares close to the time the Deutsche Telekom/VoiceStream merger is
completed.

     If a cash adjustment is made, then for purposes of determining the number
of Deutsche Telekom shares to which a holder is entitled in lieu of the amount
by which the cash portion of the Deutsche Telekom/VoiceStream merger
consideration is reduced, the price of Deutsche Telekom ordinary shares is
calculated by taking the volume weighted average trading price in euros of
Deutsche Telekom ordinary shares on the Frankfurt Stock Exchange on seven
trading days randomly selected from the 15 trading days immediately preceding
the date the determination is to be made, converted into U.S. dollars at a fixed
exchange rate of one euro to 0.9216 of a U.S. dollar. If this calculated average
price would otherwise be less than 33 euros, then 33 euros, and not the
calculated average price, will be used. If the calculated average price is less
than 33 euros or if the euro depreciates from the fixed exchange rate of one
euro to 0.9216 of a U.S. dollar, the aggregate market value of the Deutsche
Telekom shares that VoiceStream

                                       125
<PAGE>   144

shareholders receive to compensate for the reduction in cash consideration
generally would be less than the amount by which the cash consideration was
reduced to permit delivery of the required tax opinion.

     Other Potential Adjustments.  The amount and form of the Deutsche
Telekom/VoiceStream merger consideration will be adjusted in the event that
before the completion of the Deutsche Telekom/VoiceStream merger:

     - a reclassification, split-up, stock-split, reverse stock-split, stock
       dividend, stock combination, recapitalization, redenomination of share
       capital, merger or similar transaction or an exchange offer causes a
       change to the Deutsche Telekom ordinary shares outstanding, or the number
       of Deutsche Telekom ordinary shares represented by a Deutsche Telekom ADS
       is changed, or

     - all of the outstanding Deutsche Telekom ordinary shares, or more than 80%
       of the outstanding Deutsche Telekom ordinary shares pursuant to an
       exchange offer for all outstanding Deutsche Telekom shares, are changed
       into or exchanged for a different number or kind of shares of Deutsche
       Telekom, or into shares of another entity owning more than 80% of the
       Deutsche Telekom shares.

     For example, if prior to completion of the Deutsche Telekom/VoiceStream
merger, Deutsche Telekom, in order to facilitate future acquisitions, were to
establish a new German holding company that acquired through an exchange offer
more than 80% of the outstanding Deutsche Telekom shares, holders of VoiceStream
common shares would receive shares of the new holding company instead of
Deutsche Telekom shares in the Deutsche Telekom/VoiceStream merger.

     Treatment of Other Capital Stock, Warrants and Exchange Rights

     2 1/2% Convertible Junior Preferred Shares.  On                , 2000,
three days before the record date for the VoiceStream special meeting, each
2 1/2% convertible junior preferred share of VoiceStream, par value $0.001 per
share, was converted into VoiceStream common shares, at the conversion rate in
effect on the conversion date under the terms of that series of VoiceStream
preferred shares.

     Omnipoint 7% Convertible Preferred Shares.  If the Deutsche
Telekom/VoiceStream merger is not completed before May 1, 2001, then at any time
on or after May 1, 2001 until the Deutsche Telekom/VoiceStream merger is
completed, Deutsche Telekom may, subject to some restrictions, require
VoiceStream to issue a notice of redemption with respect to all the shares of 7%
cumulative convertible preferred shares, par value $0.001, of Omnipoint, at the
redemption price in effect on the redemption date, as provided by the terms of
that series of preferred shares. If all the 7% convertible preferred shares have
not been redeemed before the Deutsche Telekom/VoiceStream merger is completed,
and at any time the holders become entitled to receive Deutsche Telekom ordinary
shares and/or a cash payment, then (1) any Deutsche Telekom ordinary shares to
which the holders are entitled will be issued by a special trust established for
the benefit of the holders of the 7% convertible preferred shares and (2) any
cash payment to which the holders are entitled will be paid by Deutsche Telekom.

     Voting Preferred Shares Issued to Deutsche Telekom.  The VoiceStream voting
preferred shares acquired by Deutsche Telekom under the investment agreements
described under "The Deutsche Telekom Investment Agreements" will remain
outstanding and will not be affected by the Deutsche Telekom/VoiceStream merger.

     Omnipoint Warrants.  If any of the warrants granted pursuant to the
Omnipoint remainder warrant certificate have not been exercised before the
Deutsche Telekom/VoiceStream merger is completed and a holder of warrants
becomes entitled to Deutsche Telekom ordinary shares at any time after the
Deutsche Telekom/VoiceStream merger, any Deutsche Telekom ordinary shares to
which the warrant holder becomes entitled will be issued from a special trust
established for the benefit of the warrant holders and any cash to which the
warrant holder becomes entitled will be paid by Deutsche Telekom. These warrants
expire by their terms on August 2, 2001.

                                       126
<PAGE>   145

     Cook Inlet Exchange Rights.  If any of the Cook Inlet Partners (who are
identified below) receive VoiceStream common shares before the Deutsche
Telekom/VoiceStream merger is completed as a result of exercising their rights
to exchange interests in any of the Cook Inlet Joint Ventures (which are
identified below) or their affiliates for VoiceStream common shares, such Cook
Inlet Partners will have all the rights with respect to those VoiceStream common
shares which a VoiceStream stockholder has.

     To the extent that any of the Cook Inlet Partners have not received
VoiceStream common shares before the Deutsche Telekom/VoiceStream merger is
completed in respect of their exchange rights, those Cook Inlet Partners will be
entitled to receive the consideration that they are entitled to receive pursuant
to their exchange rights.

     To the extent that any of the Cook Inlet Partners are entitled to receive
Deutsche Telekom shares on or after the date the Deutsche Telekom/VoiceStream
merger is completed, the Deutsche Telekom shares will be delivered from a
special trust established for the benefit of such Cook Inlet Partners, and any
cash to which such Cook Inlet Partners become entitled will be paid by Deutsche
Telekom.

     The "Cook Inlet Partners" are Cook Inlet Telecommunications, Inc., SSPCS
Corporation, Providence Media Partners L.P., Cook Inlet GSM Inc., Providence
Media Partners III L.P. and Providence Equity Operating Partners III.

     The "Cook Inlet Joint Ventures" are Cook Inlet VoiceStream PV/SS PCS, L.P.,
Cook Inlet VoiceStream PCS, LLC, Cook Inlet/VS GSM II PCS, LLC and Cook Inlet/VS
GSM III PCS, LLC.

     Election and Exchange of Certificates Representing VoiceStream Common
Shares

     Deutsche Telekom will appoint an escrow agent to serve in connection with
the Deutsche Telekom/VoiceStream merger.

     At least 45 days before the Deutsche Telekom/VoiceStream merger is expected
to be completed, Deutsche Telekom and VoiceStream intend to mail to each
registered holder of VoiceStream common shares an election form with
instructions for making the all-stock election or the all-cash election or for
receiving the mixed consideration, and a letter of transmittal that the holder
must properly complete and deliver to the escrow agent with the holder's
VoiceStream share certificates before the election deadline. Any registered
holder of VoiceStream common shares that fails to submit properly completed
election forms before the election deadline will be deemed to have made a mixed
election and will automatically receive $30 in cash and 3.2 Deutsche Telekom
shares, subject to adjustment, when the holder delivers to the escrow agent the
holder's VoiceStream share certificates, together with a properly completed
letter of transmittal.

     The election deadline will be five business days before the Deutsche
Telekom/VoiceStream merger is expected to be completed. Since the actual
election deadline is not yet known, Deutsche Telekom and VoiceStream will use
their best efforts to make a public announcement notifying VoiceStream
stockholders of the election deadline at least five business days before that
deadline. Any holder may revoke in writing that holder's previously submitted
election forms until the election deadline.

     The escrow agent will exchange VoiceStream share certificates for American
depositary receipts representing Deutsche Telekom ADSs or, if a VoiceStream
stockholder properly elects, certificates representing Deutsche Telekom ordinary
shares. The election forms and the letter of transmittal mailed to VoiceStream
stockholders will contain an "ordinary share election" form that can be used by
a stockholder to elect to receive that stockholder's stock consideration in
Deutsche Telekom ordinary shares.

     After a record holder of VoiceStream common shares delivers certificates
for those shares and a properly completed letter of transmittal to the escrow
agent, the escrow agent will deliver to that holder:

     - the number of whole Deutsche Telekom ADSs or Deutsche Telekom ordinary
       shares included in the Deutsche Telekom/VoiceStream merger consideration
       in respect of those VoiceStream common shares, subject to proration and
       adjustment; and

                                       127
<PAGE>   146

     - a check in the amount (after giving effect to any required tax
       withholdings) of (1) any cash consideration payable to that holder, plus
       (2) any cash in lieu of any fractional interest in Deutsche Telekom ADSs
       or Deutsche Telekom ordinary shares on the terms described below, plus
       (3) any cash dividends or other distributions that the holder has the
       right to receive, including dividends or other distributions payable with
       respect to the holders of Deutsche Telekom ADSs or Deutsche Telekom
       ordinary shares with a record date after the completion of the Deutsche
       Telekom/VoiceStream merger and a payment date on or before the date the
       holder properly delivers VoiceStream share certificates to the escrow
       agent.

     The escrow agent will not deliver fractional Deutsche Telekom ADSs or
fractional Deutsche Telekom ordinary shares in connection with the Deutsche
Telekom/VoiceStream merger. Instead, each holder of VoiceStream common shares
exchanged in the Deutsche Telekom/VoiceStream merger that would otherwise have
received a fraction of a Deutsche Telekom ADS or Deutsche Telekom ordinary share
will be entitled to receive a cash payment representing that holder's
proportionate interest in the net proceeds from the sale by the escrow agent of
the aggregate of the fractions of Deutsche Telekom ADSs and Deutsche Telekom
ordinary shares that would otherwise be issued on the NYSE and the Frankfurt
Stock Exchange, respectively. Deutsche Telekom will pay all commissions,
transfer taxes and out-of-pocket costs, including the expenses and compensation
of the escrow agent, incurred in connection with the sale of the Deutsche
Telekom ADSs and Deutsche Telekom ordinary shares.

     VoiceStream common shares that are surrendered to the escrow agent will be
canceled. No interest will be paid or accrued on any amount payable to holders
of VoiceStream common shares. In addition, no holder of VoiceStream common
shares will receive any dividends or other distributions with respect to
Deutsche Telekom ADSs or Deutsche Telekom ordinary shares to which the holder is
entitled under the Deutsche Telekom/VoiceStream merger agreement until that
holder's VoiceStream share certificate is surrendered to the escrow agent with a
properly completed letter of transmittal.

     If any Deutsche Telekom ADSs or Deutsche Telekom ordinary shares are to be
delivered to a person other than the registered holder of the VoiceStream common
shares represented by the VoiceStream share certificates surrendered to the
escrow agent:

     - such VoiceStream share certificates must be properly endorsed or
       otherwise be in proper form for transfer; and

     - the person requesting delivery must pay to the escrow agent any transfer
       or other taxes required as a result of delivery to a person other than
       the registered holder, or establish, to the satisfaction of the escrow
       agent, that the tax has been paid or is not payable.

     Treatment of Options and Restricted Stock

     VoiceStream Options.  If the Deutsche Telekom/VoiceStream merger is
completed, each outstanding VoiceStream stock option will be converted into an
option to acquire, from a trust established for the benefit of holders of
VoiceStream stock options, 3.7647 Deutsche Telekom ordinary shares for each
VoiceStream common share subject to that VoiceStream option (rounded if
necessary to the nearest whole Deutsche Telekom ordinary share). The exercise
price per Deutsche Telekom ordinary share for each of these options will be the
exercise price per VoiceStream common share applicable to that option before
completion of the Deutsche Telekom/VoiceStream merger divided by 3.7647. The
replacement options generally will have the same terms and conditions as were
applicable under VoiceStream option plans.

     VoiceStream Restricted Shares.  If the Deutsche Telekom/VoiceStream merger
is completed, each outstanding VoiceStream restricted share will be converted
into a right to receive, from a trust established for the benefit of holders of
VoiceStream restricted shares, 3.7647 Deutsche Telekom shares. The Deutsche
Telekom ordinary shares issued to the former holders of VoiceStream restricted
shares will have the same terms and conditions and be subject to the same
vesting provisions as were applicable under the VoiceStream restricted share
award plans.

     - take any action that would be reasonably likely to (1) prevent or impede
       the Deutsche Telekom/VoiceStream merger from qualifying as a
       reorganization within the meaning of Section 368(a) of the U.S. tax code
       or (2) cause VoiceStream stockholders to recognize gain in the Deutsche

       a non-competition provision applicable to the business of VoiceStream or

       business outside the United States and that are in the ordinary course,
       consistent with past practice in respect of certain VoiceStream joint
       ventures.

     Acquisitions by VoiceStream.  VoiceStream generally has agreed that, until
the Deutsche Telekom/VoiceStream merger is completed, it and its subsidiaries
will not engage in an acquisition transaction, including any acquisitions of
additional FCC licenses or increase an investment in another entity, with three
significant exceptions:

     (1) VoiceStream is permitted to swap or exchange any of its property for
         similar property of substantially equivalent value as long as any one
         swap relates to no more than 5 million POPs and all swaps together do
         not relate to more than 10 million POPs;

     (2) VoiceStream is permitted to make acquisitions of up to $750 million
         (including assumptions of debt) without Deutsche Telekom's consent as
         long as the consideration paid in any single acquisition does not
         exceed $500 million (including assumptions of debt), and does not
         include any VoiceStream shares; and

     (3) VoiceStream may make any other acquisition, and the acquisition may
         include VoiceStream shares as part of the consideration paid, as long
         as the acquisition is approved in advance by an

                                       131
<PAGE>   150

         acquisition committee consisting of four agreed-upon members of
         Deutsche Telekom's senior management. The Deutsche Telekom/VoiceStream
         merger agreement contains specific procedures and timetables for
         streamlined review by the acquisition committee of acquisitions
         proposed to it by VoiceStream, and failure by the acquisition committee
         to respond within the designated time periods is deemed to be approval
         by Deutsche Telekom of the proposed acquisition.

     In addition, if VoiceStream chooses to participate in any auction of FCC
licenses or spectrum rights, VoiceStream and Deutsche Telekom have agreed to
cooperate in accordance with specific procedures to agree upon maximum amounts
that VoiceStream may bid in the auction. If the acquisition committee denies its
consent to an acquisition proposed by VoiceStream, or VoiceStream and the
acquisition committee fail to agree upon maximum bids for a license or spectrum
auction prior to the tenth business day preceding the scheduled auction date,
then the parties have agreed that any officer, director, stockholder or
affiliate of VoiceStream, or any combination of them, may make such acquisition
or participate in such auction for his, her, its or their own account.

     Dispositions by VoiceStream.  VoiceStream generally has agreed that, until
the Deutsche Telekom/VoiceStream merger is completed, it and its subsidiaries
will not sell or dispose of any of their assets, with three significant
exceptions:

     (1) VoiceStream may swap or exchange any of its property for similar
         property of substantially equivalent value as long as any one swap
         relates to no more than 5 million POPs and all swaps together do not
         relate to more than 10 million POPs;

     (2) VoiceStream may sell or dispose of assets in the ordinary course of
         business consistent with past practice; and

     (3) VoiceStream may sell or dispose of assets as may be required by law or
         any governmental or regulatory authority as necessary to enable or
         facilitate completion of the Deutsche Telekom/VoiceStream merger.

     Covenants of Deutsche Telekom.  Except as contemplated by the Deutsche
Telekom/VoiceStream merger agreement, Deutsche Telekom has agreed that, before
the Deutsche Telekom/VoiceStream merger is completed, Deutsche Telekom and its
subsidiaries will not do any of the following without VoiceStream's prior
written consent:

     - except for the purpose of using or increasing Deutsche Telekom's
       authorized capital or as necessary for the conduct of its business, amend
       or propose to amend the memorandum and articles of association or
       management board rules of procedure or other comparable organizational
       document of Deutsche Telekom in any manner that would be adverse to
       VoiceStream or its stockholders;

     - declare or pay dividends payable in cash, stock, property or otherwise
       with respect to Deutsche Telekom capital stock, except for regular annual
       cash dividends in a manner consistent with past practice;

     - repurchase, redeem or otherwise acquire any shares of its capital stock
       or any securities convertible or exercisable for or into shares of its
       capital stock, except for repurchases, redemptions or acquisitions not
       exceeding 10% of the total number of Deutsche Telekom ordinary shares
       outstanding on July 23, 2000;

     - reclassify, recapitalize, restructure or engage in a similar transaction
       that results in the, direct or indirect, receipt by holders of Deutsche
       Telekom ordinary shares of any assets, property or cash for Deutsche
       Telekom ordinary shares;

     - take action that would be reasonably likely to prevent or impede the
       Deutsche Telekom/VoiceStream merger from qualifying as a reorganization
       within the meaning of Section 368(a) of the U.S. tax code or cause
       VoiceStream stockholders to recognize gain under Section 367(a)(1) of the
       U.S. tax code in the Deutsche Telekom/VoiceStream merger; and

                                       132
<PAGE>   151

     - take action that would reasonably be likely to materially adversely
       affect or materially adversely delay the ability of the parties to obtain
       any required regulatory approval or to complete the transactions
       contemplated in the Deutsche Telekom/VoiceStream merger agreement.

      - Important Exception:  Deutsche Telekom may make acquisitions as long as
        the acquisitions, individually or in the aggregate, are not reasonably
        likely to prevent the completion of the Deutsche Telekom/VoiceStream
        merger.

     Offers for Alternative Transactions

     VoiceStream has agreed not to, has agreed not to authorize its officers,
directors or employees to, and has agreed to use its reasonable efforts to cause
its advisors and representatives not to:

     - solicit, initiate or knowingly encourage, or knowingly take any other
       action designed to facilitate, any alternative transaction (which we
       define below) to the Deutsche Telekom/VoiceStream merger, or

     - participate in any substantive discussions or negotiations regarding any
       alternative transaction to the Deutsche Telekom/VoiceStream merger.

     However, if, at any time before VoiceStream stockholders approve the
Deutsche Telekom/VoiceStream merger, VoiceStream receives an unsolicited
proposal for an alternative transaction, then VoiceStream may, after giving
Deutsche Telekom 48 hours advance notice:

     (1) furnish information with respect to VoiceStream pursuant to a
         confidentiality agreement substantially similar to the confidentiality
         agreement in place between VoiceStream and Deutsche Telekom; and

     (2) engage in discussions and negotiations with the persons that made such
         proposal,

but only if:

     (1) the VoiceStream board of directors has determined in good faith that
         providing information to the third party or participating in
         negotiations or discussions could be reasonably expected to result in a
         superior proposal (which we define below) being made; and

     (2) VoiceStream is not otherwise in breach of its obligations described
         above not to solicit or engage in discussions regarding an alternative
         transaction.

  Important Definitions:

     "alternative transaction" means any of the following:

     - a transaction or series of transactions in which any third party would
       acquire, directly or indirectly, beneficial ownership of more than 20% of
       the outstanding VoiceStream shares;

     - any acquisition of or business combination with VoiceStream or any of its
       significant subsidiaries by a merger or other business combination, other
       than any transaction that would be permitted under the Deutsche
       Telekom/VoiceStream merger agreement; or

     - any transaction in which any third party would acquire, directly or
       indirectly, control of assets of VoiceStream or any of its subsidiaries
       for consideration equal to 20% or more of the fair market value of all of
       the outstanding VoiceStream common shares on July 23, 2000.

     "superior proposal" means any proposal made by a third party to enter into
an alternative transaction which the VoiceStream board of directors determines
in its good faith judgment to be more favorable to VoiceStream's stockholders
than the Deutsche Telekom/VoiceStream merger.

     VoiceStream also has agreed to notify Deutsche Telekom promptly of any
request for information or of any proposal in connection with an alternative
transaction, including the material terms of the request or proposal and the
identity of the person making it, and VoiceStream has agreed to keep Deutsche
Telekom
                                       133
<PAGE>   152

informed of the status of any alternative transaction. In addition, VoiceStream
agreed to cease any solicitations, discussions or negotiations that existed at
the time the Deutsche Telekom/VoiceStream merger agreement was signed.

     VoiceStream Board of Directors' Recommendation

     The Deutsche Telekom/VoiceStream merger agreement requires the VoiceStream
board of directors:

     (1) to recommend that the VoiceStream stockholders approve the Deutsche
         Telekom/VoiceStream merger agreement;

     (2) not to withdraw, modify or qualify, or to propose publicly to withdraw,
         modify or qualify, its recommendation in a manner adverse to Deutsche
         Telekom;

     (3) not to approve or recommend, or to propose publicly to approve or
         recommend, any alternative transaction; and

     (4) not to cause VoiceStream to agree to engage in any alternative
         transactions.

     However, if the VoiceStream board of directors receives a superior proposal
before VoiceStream stockholders approve the Deutsche Telekom/VoiceStream merger,
the VoiceStream board of directors may inform VoiceStream stockholders that it
no longer recommends approval of the Deutsche Telekom/VoiceStream merger, if:

     - VoiceStream sends Deutsche Telekom written notice that VoiceStream has
       received a superior proposal (which states the terms of the superior
       proposal and identifies the proposer) and that VoiceStream intends to
       change its recommendation regarding the Deutsche Telekom/VoiceStream
       merger; and

     - two business days have passed since Deutsche Telekom received the notice.
       In addition, during those two business days, VoiceStream must give
       Deutsche Telekom reasonable opportunity to make adjustments in the terms
       of the Deutsche Telekom/VoiceStream merger agreement that would enable
       the VoiceStream board of directors to maintain its recommendation to
       approve the Deutsche Telekom/VoiceStream merger.

     The Deutsche Telekom/VoiceStream merger agreement also permits VoiceStream
to take and disclose to VoiceStream stockholders a position contemplated by Rule
14d-9 or Rule 14e-2(a) under the Exchange Act or to make any other disclosure to
VoiceStream stockholders if, in the good faith judgment of the VoiceStream board
of directors, after receipt of advice from outside counsel, failure to disclose
would result in a reasonable likelihood that the VoiceStream board of directors
would breach its duties to VoiceStream stockholders under applicable law.

     Submission of Deutsche Telekom/VoiceStream Merger Agreement to Stockholder
Vote.  The Deutsche Telekom/VoiceStream merger agreement requires VoiceStream to
submit the Deutsche Telekom/VoiceStream merger agreement to a stockholder vote
at the VoiceStream special meeting even if the VoiceStream board of directors no
longer recommends approval of the Deutsche Telekom/VoiceStream merger.

     Additional Agreements

     The Deutsche Telekom/VoiceStream merger agreement contains a number of
other covenants and agreements by or between VoiceStream and Deutsche Telekom on
subjects, including:

     - timely filing accurate financial statements with the SEC by VoiceStream
       or Deutsche Telekom after the signing of the Deutsche Telekom/VoiceStream
       merger agreement;

     - notification of facts, events or circumstances that are reasonably likely
       to cause any representation or warranty contained in the Deutsche
       Telekom/VoiceStream merger agreement to become untrue or inaccurate or to
       result in a material adverse effect on either VoiceStream or Deutsche
       Telekom;

                                       134
<PAGE>   153

     - permitting reasonable access to each other's information, employees and
       properties;

     - public announcements relating to the transactions contemplated by the
       Deutsche Telekom/VoiceStream merger agreement;

     - using reasonable best efforts to obtain necessary tax opinions and
       representation letters;

     - using reasonable best efforts to cause the Deutsche Telekom/VoiceStream
       merger to qualify as a reorganization within the meaning of Section
       368(a) of the U.S. tax code and to avoid gain recognition to VoiceStream
       shareholders in the Deutsche Telekom/VoiceStream merger under Section
       367(a)(1) of the U.S. tax code; and

     - avoidance of actions that would cause the transactions contemplated by
       the Deutsche Telekom/VoiceStream merger agreement to be subject to
       certain takeover laws.

     In addition, Deutsche Telekom has agreed to take all steps necessary to
cause the new Deutsche Telekom ADSs and the Deutsche Telekom ordinary shares to
become listed on the Frankfurt Stock Exchange and the NYSE, respectively.

     VoiceStream's Nominations to Deutsche Telekom Organizational Bodies

     Deutsche Telekom has agreed that, after the Deutsche Telekom/VoiceStream
merger is completed, it will use all reasonable efforts to recommend to the
Deutsche Telekom shareholders and the Deutsche Telekom organizational bodies
that one current member of the Deutsche Telekom supervisory board be replaced by
a person nominated by VoiceStream. Deutsche Telekom has agreed that, after the
Deutsche Telekom/VoiceStream merger is completed, it will use all reasonable
efforts to cause its T-Mobile subsidiary to recommend to the shareholders and
organizational bodies of T-Mobile that one VoiceStream nominee be appointed or
elected to each of the T-Mobile management board, T-Mobile supervisory board and
the T-Mobile executive committee.

     The VoiceStream nominees will be selected in consultation with Deutsche
Telekom and must be reasonably acceptable to Deutsche Telekom.

     Efforts to Complete the Deutsche Telekom/VoiceStream Merger

     VoiceStream and Deutsche Telekom have agreed:

     - to take or cause to be taken all actions and to do or cause to be done
       all things necessary, proper or advisable to complete the Deutsche
       Telekom/VoiceStream merger, including any actions to be taken after the
       completion of the Deutsche Telekom/VoiceStream merger to permit the
       issuance of the Deutsche Telekom/VoiceStream merger consideration under
       German law and the rules of the Frankfurt Stock Exchange;

     - to obtain in a timely manner all necessary consents, permits, approvals
       or waivers from any governmental or regulatory authority which are
       necessary for the completion of the Deutsche Telekom/VoiceStream merger;

     - to promptly prepare and file all required notifications under U.S. and
       European Union antitrust laws and to comply with any requests for
       additional information, and obtain termination of any applicable waiting
       periods or obtain any required approvals as promptly as practicable; and

     - to take all actions within its control necessary to obtain any required
       regulatory approvals (which the Deutsche Telekom/VoiceStream merger
       agreement limits principally to any required FCC approval, antitrust
       clearances and clearances under the Exon-Florio Defense Protection Act of
       1956).

     Important Exception:  Neither VoiceStream nor Deutsche Telekom is required
to take any of the actions described above that would result in a "burdensome
condition." The meaning of "burdensome condition" is explained under
"-- Important Definitions."

                                       135
<PAGE>   154

     VoiceStream and Deutsche Telekom also have agreed:

     - to cooperate with each other to respond to inquiries by governmental or
       regulatory authorities, and to promptly inform each other of any material
       communications received from any governmental or private party relating
       to the Deutsche Telekom/VoiceStream merger;

     - to consult with each other in advance of any meeting or conference with,
       or of making any filing or other written submission to, any governmental
       or regulatory authority, and, if permitted by that authority, to give
       each other the opportunity to participate in those meetings and
       conferences, or to review and approve any filing or other written
       submission; and

     - to cooperate to eliminate or reduce to the extent possible any
       illegality, forfeiture or loss on the part of Deutsche Telekom,
       VoiceStream or their respective subsidiaries that may result from the
       completion of the Deutsche Telekom/VoiceStream merger.

     Indemnification and Insurance

     For a period of six years after the Deutsche Telekom/VoiceStream merger is
completed, the surviving corporation of the Deutsche Telekom/VoiceStream merger
is required by the Deutsche Telekom/VoiceStream merger agreement to:

     - maintain in effect the current provisions regarding indemnification of
       officers and directors contained in the charter and bylaws and any
       indemnification agreements of VoiceStream and each of its subsidiaries;

     - indemnify the directors and officers of VoiceStream to the fullest extent
       to which VoiceStream is permitted to indemnify those officers and
       directors under its charter and bylaws and applicable law; and

     - maintain VoiceStream's current policies of directors' and officers'
       insurance with respect to claims arising from facts or events which
       occurred on or before the completion of the Deutsche Telekom/VoiceStream
       merger, except that the surviving corporation may substitute policies of
       at least the same coverage and amounts, containing terms and conditions
       that are no less advantageous to the indemnified parties.

     However, during that six-year period, the surviving corporation is not
required to expend in any year an amount in excess of 250% of the annual
aggregate premiums currently paid by VoiceStream for such coverage. If the
aggregate expenditure on coverage exceeds that amount, Deutsche Telekom has
agreed that the surviving corporation will use its best efforts to obtain as
much insurance as can be obtained for that amount.

     In addition, after the completion of the Deutsche Telekom/VoiceStream
merger both Deutsche Telekom and the surviving corporation will, to the fullest
extent permitted under applicable law, indemnify and hold harmless each present
and former director, officer, employee and agent of VoiceStream or any of its
subsidiaries against any costs or expenses arising out of or relating to any
action or omission occurring or alleged to occur prior to the completion of the
Deutsche Telekom/VoiceStream merger or arising out of or pertaining to the
proposed Deutsche Telekom/VoiceStream merger. Both Deutsche Telekom and the
surviving corporation will also pay each indemnified party's out-of-pocket
expenses incurred in connection with any indemnifiable claim, including
reasonable fees and expenses of counsel.

     Employee Benefits

     Following the completion of the Deutsche Telekom/VoiceStream merger,
Deutsche Telekom will cause the surviving corporation or its successor to honor
all VoiceStream employee benefit plans and compensation arrangements and
agreements in accordance with their terms as in effect immediately before the
Deutsche Telekom/VoiceStream merger is completed. In addition, Deutsche Telekom
has agreed that for a period of not less than two years following the completion
of the Deutsche Telekom/VoiceStream merger, the current and former employees of
VoiceStream and its subsidiaries will be provided with
                                       136
<PAGE>   155

compensation and employee benefits that are not less favorable in the aggregate
than those provided to VoiceStream's employees immediately before the completion
of the Deutsche Telekom/VoiceStream merger. Discretionary equity and
equity-based awards will remain discretionary.

     Following the completion of the Deutsche Telekom/VoiceStream merger, each
current and former employee of VoiceStream and its subsidiaries will be
immediately eligible to participate in any new Deutsche Telekom employee benefit
plan, to the extent that such plan replaces coverage under a comparable
VoiceStream employee benefit plan or compensation agreement or arrangement in
which the employee participated immediately before the completion of the
Deutsche Telekom/VoiceStream merger. The Deutsche Telekom/VoiceStream merger
agreement also specifies the treatment of pre-existing conditions, deductibles
and service credit with respect to current and former employees of VoiceStream
under any benefit plans of Deutsche Telekom or its subsidiaries that any current
or former employees of VoiceStream participate in after completion of the
Deutsche Telekom/VoiceStream merger.

     VoiceStream and Deutsche Telekom agreed to cooperate to develop a mutually
acceptable retention plan for senior management employees of VoiceStream.

     Finally, for a period of at least two years following the completion of the
Deutsche Telekom/VoiceStream merger, Deutsche Telekom has agreed to continue
VoiceStream's existing severance policy without any amendments adverse to the
current and former employees of VoiceStream and its subsidiaries.

the following conditions:

     - Representations and Warranties.

       Telekom/VoiceStream merger is completed, unless all of VoiceStream's
       failures to comply with such agreements taken together do not, or would
       not reasonably be expected to, result in a material adverse effect on
       Deutsche Telekom or Deutsche Telekom's mobile telecommunications
       business, in each case assuming that the Deutsche Telekom/VoiceStream
       merger had been completed and VoiceStream had become a part of Deutsche

       that any other acquisition in the mobile telecommunication industry
       entered into or completed by Deutsche Telekom after July 23, 2000 had

     Termination and Termination Fee

     Right to Terminate.  The Deutsche Telekom/VoiceStream merger agreement may
be terminated at any time before the closing in any of the following ways:

     - by mutual written consent;

     - by either Deutsche Telekom and VoiceStream:

        -- if the Deutsche Telekom/VoiceStream merger is permanently restrained,
           enjoined or otherwise prohibited by a governmental order, decree,
           ruling or other action, and the order, decree, ruling or other action
           has become final and nonappealable;

        -- if in connection with the grant of a requisite regulatory approval, a
           burdensome condition is imposed and the ruling imposing the condition
           has become final and nonappealable. The meaning of "burdensome
           condition" is explained below under "-- Important Definitions";

        -- at any time that is not less than 15 days after any statute, rule,
           decree or injunction has been enacted, entered, promulgated or
           enforced by any governmental or regulatory authority (other than a
           court) that has the effect of making any of the conditions to closing
           described above under "-- Closing Conditions -- Legality" and
           "-- Closing Conditions -- Required Regulatory Approvals" incapable of
           being satisfied by September 30, 2001, in the case of a termination
           by VoiceStream, or December 31, 2001, in the case of a termination by
           Deutsche Telekom; or
                                       139
<PAGE>   158

        -- if VoiceStream's stockholders fail to approve the Deutsche
           Telekom/VoiceStream merger at the VoiceStream special meeting.

     - by VoiceStream:

        -- if the Deutsche Telekom/VoiceStream merger is not completed by
           September 30, 2001 (unless VoiceStream's failure to fulfill its
           obligations under the Deutsche Telekom/ VoiceStream merger agreement
           caused the delay) or if any of the conditions to VoiceStream's
           obligation to complete the Deutsche Telekom/VoiceStream merger
           becomes incapable of being satisfied before that date;

        -- if Deutsche Telekom breaches or fails to perform any of its
           representations or covenants in any material respect and the breach
           or failure cannot be cured by Deutsche Telekom before September 30,
           2001, or, if curable, is not cured by Deutsche Telekom within 30
           days, and such breach renders any conditions to VoiceStream's
           obligations incapable of being satisfied by September 30, 2001; or

        -- on 48 hours notice to Deutsche Telekom, if the calculated average
           price of Deutsche Telekom ordinary shares to be used in any
           tax-related adjustment to the amount of the cash merger consideration
           is less than 33 euros. The calculated average price of Deutsche
           Telekom ordinary shares to be used in any adjustment, if necessary,
           will be the average trading price of Deutsche Telekom ordinary shares
           on the Frankfurt Stock Exchange on seven trading days randomly
           selected from the 15 trading days immediately preceding the date on
           which any adjustment determination is to be made, as described above
           under "-- Consideration To Be Received in the Deutsche
           Telekom/VoiceStream Merger -- Adjustments".

     - by Deutsche Telekom:

        -- if the Deutsche Telekom/VoiceStream merger is not completed by
           December 31, 2001 (unless Deutsche Telekom's failure to fulfill its
           obligations under the Deutsche Telekom/ VoiceStream merger agreement
           caused the delay) or if any of the conditions to Deutsche Telekom's
           obligation to complete the Deutsche Telekom/VoiceStream merger
           becomes incapable of being satisfied before that date; or

        -- if VoiceStream breaches or fails to perform any of its
           representations or covenants in any material respect and the breach
           or failure cannot be cured by VoiceStream before December 31, 2001,
           or, if curable, is not cured by VoiceStream within 30 days, and such
           breach renders any conditions to Deutsche Telekom's obligations
           incapable of being satisfied by December 31, 2001.

     - Termination Fees Payable to Deutsche Telekom.  VoiceStream has agreed to
       pay Deutsche Telekom a termination fee of $1 billion if all three of the
       following events occur:

        (1) after July 23, 2000 and before the VoiceStream special meeting, a
            proposal for certain types of alternative transactions is announced
            or publicly disclosed and not withdrawn;

        (2) the Deutsche Telekom/VoiceStream merger agreement is terminated by
            either party because VoiceStream's stockholders do not approve the
            Deutsche Telekom/VoiceStream merger at the VoiceStream special
            meeting; and

        (3) within six months after the termination of the Deutsche
            Telekom/VoiceStream merger agreement, VoiceStream enters into a
            definitive agreement with any third party with respect to certain
            types of alternative transactions.

     In that circumstance, VoiceStream would pay to Deutsche Telekom the
termination fee no later than one business day after the signing of the
definitive agreement with the third party.

     For purposes of determining whether a termination fee is payable, the term
"alternative transaction" has the meaning described above under "-- Offers for
Alternative Transactions", except that the 20%

                                       140
<PAGE>   159

thresholds are treated as references to "50%," and mergers or business
combinations in which VoiceStream stockholders would continue to hold at least
65% of the outstanding stock of the entity surviving the transaction are not
considered to be "alternative transactions".

     Expenses

     Whether or not the Deutsche Telekom/VoiceStream merger is completed, all
costs and expenses incurred in connection with the Deutsche Telekom/VoiceStream
merger and the Deutsche Telekom/VoiceStream merger agreement transactions will
be paid by the party incurring the expense, except that Deutsche Telekom and
VoiceStream will share equally the costs and expenses of filing and printing the
Form F-4 registration statement and this document. Deutsche Telekom, VoiceStream
and Powertel have each shared equally the costs and expenses of the filing fees
paid under the HSR Act.

     Amendment; Waiver; Assignment

     VoiceStream and Deutsche Telekom and merger subsidiary may amend the
Deutsche Telekom/VoiceStream merger agreement by written agreement prior to
completion of the Deutsche Telekom/VoiceStream merger, but after VoiceStream's
stockholders have approved the Deutsche Telekom/VoiceStream merger agreement, no
amendment may be made which by law requires further stockholder approval without
such approval being obtained.

     At any time before the Deutsche Telekom/VoiceStream merger is completed,
VoiceStream and Deutsche Telekom and merger subsidiary may (1) extend the time
for the performance of any of the obligations or other acts of the others, (2)
waive any inaccuracies in the representations and warranties contained in the
Deutsche Telekom/VoiceStream merger agreement or in any document delivered under
the Deutsche Telekom/VoiceStream merger agreement and (3) waive compliance with
any of the agreements or conditions contained in the Deutsche
Telekom/VoiceStream merger agreement.

     Deutsche Telekom, VoiceStream and merger subsidiary may not assign the
Deutsche Telekom/VoiceStream merger agreement or any of the rights, interests or
obligations under the Deutsche Telekom/VoiceStream merger agreement, in whole or
in part, to any other person, without the prior written consent of the
non-assigning party; except that (1) Deutsche Telekom may assign the Deutsche
Telekom/VoiceStream merger agreement to a corporation which owns more than 80%
of the Deutsche Telekom ordinary shares and which succeeds to all of the rights
and obligations of Deutsche Telekom under the Escrow Agency Agreement executed
pursuant to the Deutsche Telekom/VoiceStream merger agreement and (2) merger
subsidiary may assign the agreement to an entity which is a direct, wholly-
owned subsidiary of the entity to which Deutsche Telekom assigned the Deutsche
Telekom/Powertel merger agreement pursuant to (1) above.

     Important Definitions

     Burdensome Condition.  As used in the Deutsche Telekom/VoiceStream merger
agreement, "burdensome condition" is a condition that, individually or together
with other conditions, would reasonably be expected to have a material adverse
effect on Deutsche Telekom or its mobile telecommunications business, in each
case assuming that the Deutsche Telekom/VoiceStream merger had been completed
and VoiceStream had become a part of Deutsche Telekom or its mobile
telecommunications business, and assuming that any other acquisition in the
mobile telecommunication industry entered into or completed by Deutsche Telekom
after July 23, 2000 had been completed.

     Material Adverse Effect.  As used in the Deutsche Telekom/VoiceStream
merger agreement, a "material adverse effect" on any company means any change in
or effect on the business of the company and its subsidiaries that is or is
reasonably likely to be materially adverse to the business, operations or
financial condition of the company and its subsidiaries, taken as a whole.

                                       141
<PAGE>   160

     However, "material adverse effect" does not include the effects of changes
or developments:

     - in the telecommunications industry, including regulatory and political
       conditions, that do not uniquely relate to Deutsche Telekom or
       VoiceStream;

     - in the U.S. or European economy;

     - in the U.S. or European securities markets; or

     - resulting from the announcement or the existence of the Deutsche
       Telekom/VoiceStream merger agreement and the transactions contemplated by
       the Deutsche Telekom/VoiceStream merger agreement.

     Only for purposes of the definition of "material adverse effect", some of
VoiceStream's joint ventures are treated as subsidiaries of VoiceStream.

     Amendment and Restatement

     The Deutsche Telekom/VoiceStream merger agreement was originally entered
into between Deutsche Telekom and VoiceStream on July 23, 2000. On September 28,
the Deutsche Telekom/VoiceStream merger agreement was amended and restated
primarily for the purpose of making merger subsidiary a party to the agreement
and other technical changes.

DEUTSCHE TELEKOM'S AGREEMENTS WITH STOCKHOLDERS OF VOICESTREAM

     In connection with the execution of the Deutsche Telekom/VoiceStream merger
agreement, VoiceStream stockholders who, in the aggregate, had sufficient voting
power as of the VoiceStream record date to approve the Deutsche
Telekom/VoiceStream merger entered into separate agreements with Deutsche
Telekom under which the stockholders agreed to vote all of their shares in favor
of the Deutsche Telekom/VoiceStream merger. We summarize the material terms of
these agreements below, but this description does not purport to describe all of
their terms and is qualified in its entirety by reference to the text of the
agreements described, copies of which have been filed as exhibits to Deutsche
Telekom's and VoiceStream's respective registration statements and are
incorporated herein by reference.

     The following stockholders and some of their affiliates have entered into
stockholder agreements with Deutsche Telekom in connection with the Deutsche
Telekom/VoiceStream merger:

     Sonera Corporation
     John W. Stanton
     The Goldman Sachs Group, Inc.
     Richard Fields and Allen & Company, Incorporated

Telekom/VoiceStream merger agreement and as discussed in the "Deutsche
Telekom/VoiceStream Merger Agreement -- Offers for Alternative Transactions," or
the liquidation or winding up of VoiceStream. Each stockholder's obligation to
vote in this manner applies whether or not the VoiceStream

                                       142
<PAGE>   161

board of directors continues to recommend the Deutsche Telekom/VoiceStream
merger to VoiceStream stockholders.

     Transfer Restrictions and Waiver of Rights

     Each of the stockholder agreements restricts or limits the ability of the
stockholder that is a party to the agreement to sell, transfer, pledge, assign
or otherwise dispose of, including by short sale or the use of derivative or
futures contracts, any shares of, or rights to purchase, VoiceStream common
stock or, until six months after completion of the Deutsche Telekom/VoiceStream
merger, Deutsche Telekom ADSs or Deutsche Telekom ordinary shares, in each case
that are subject to the stockholder agreement, except in limited circumstances,
with Deutsche Telekom's written consent or as expressly permitted by the
stockholder agreement or pursuant to the Deutsche Telekom/VoiceStream merger
agreement. In that regard, the stockholder agreements provide that:

     - unless the Deutsche Telekom/VoiceStream merger agreement has been
       terminated, until the later of January 1, 2001 and the date of the
       VoiceStream special meeting, the stockholder may not sell, transfer,
       pledge, assign or otherwise dispose of, any VoiceStream shares or rights
       that are subject to the agreement;

     - from the later of January 1, 2001 and the date of the VoiceStream special
       meeting, until the earlier of the completion of the Deutsche
       Telekom/VoiceStream merger or the termination of the Deutsche
       Telekom/VoiceStream merger agreement, the stockholder may sell or
       transfer up to an aggregate of 17.5% of the number of VoiceStream common
       shares that are subject to the agreement, which percentage increases to
       21.25% on August 1, 2001 and to 25% on September 1, 2001 if the Deutsche
       Telekom/VoiceStream merger is not completed by those dates;

     - from the completion of the Deutsche Telekom/VoiceStream merger through
       and including the three month anniversary of the completion of the
       Deutsche Telekom/VoiceStream merger, the stockholder may not sell or
       transfer any Deutsche Telekom ADSs, Deutsche Telekom ordinary shares or
       securities convertible into Deutsche Telekom ADSs or Deutsche Telekom
       ordinary shares that are subject to the agreement;

     - from the day following the three month anniversary of the completion of
       the Deutsche Telekom/VoiceStream merger, through and including the six
       month anniversary of the completion of the Deutsche Telekom/VoiceStream
       merger, the stockholder may sell or transfer up to an aggregate of 40% of
       the total number of Deutsche Telekom ADSs or Deutsche Telekom ordinary
       shares that is subject to the agreement (as calculated pursuant to the
       stockholder agreements); and

     - after the six month anniversary of the completion of the Deutsche
       Telekom/VoiceStream merger, all sale and transfer restrictions end.

     Each stockholder agreed to waive, until the earlier of the completion of
the Deutsche Telekom/VoiceStream merger or termination of the Deutsche
Telekom/VoiceStream merger agreement, any preemptive rights and, until the
earlier of (1) the later of January 1, 2001 and the date of the VoiceStream
special meeting and (2) the termination of the Deutsche Telekom/VoiceStream
merger agreement, any registration rights they may have, other than Richard
Fields and Allen & Company, Incorporated, which agreed to waive their
registration rights with respect to a certain number of VoiceStream common
shares they own. Each stockholder also agreed to terminate any of its existing
registration rights agreements with VoiceStream effective at the completion of
the Deutsche Telekom/VoiceStream merger.

     In some circumstances, if Deutsche Telekom acquires any other company for
consideration in excess of $15 billion and significant stockholders of the
acquired company enter into agreements with Deutsche Telekom, or could
reasonably be expected to enter into agreements with Deutsche Telekom, that are
more favorable to those stockholders in terms of the obligations to vote in
favor of the related transaction or to refrain from selling or transferring
shares the transfer restrictions in the stockholder agreements will be modified
to reflect the more favorable provisions or absence of restrictions, as the case
may be.

  Registration Rights

     If the existing majority shareholders of Deutsche Telekom -- the Federal
Republic of Germany and KfW -- elect to conduct a registered secondary offering
of their Deutsche Telekom shares during the period from the completion of the
Deutsche Telekom/VoiceStream merger through the first anniversary of the
completion of the Deutsche Telekom/VoiceStream merger, Deutsche Telekom agrees
to use its reasonable best efforts to obtain the agreement of the existing
majority shareholders to include in such registered offering the maximum amount
of Deutsche Telekom shares acquired in the Deutsche Telekom/VoiceStream merger
by the VoiceStream stockholders who have entered into stockholder agreements
with Deutsche Telekom. Deutsche Telekom's existing majority shareholders would
have the right to determine the number of Deutsche Telekom shares of these
VoiceStream stockholders which may be included in such secondary offering
without adversely affecting such secondary offering, on such terms and
conditions as the existing majority shareholders determine are appropriate.

  Termination

     Each of the stockholder agreements will terminate upon the earliest to
occur of:

     - the completion of the Deutsche Telekom/VoiceStream merger;

     - the termination of the Deutsche Telekom/VoiceStream merger agreement; and

     - July 23, 2002.

  No Solicitation

     Each of the stockholders agreed not to initiate or participate in, and not
to authorize any representatives to initiate or participate in, discussions or
negotiations regarding transactions or business combinations between VoiceStream
and a company other than Deutsche Telekom, except as otherwise permitted by the
Deutsche Telekom/VoiceStream merger agreement. See "The Deutsche
Telekom/VoiceStream Merger Agreement -- Offers for Alternative Transactions".

  The Stockholder Agreement with Hutchison Whampoa Ltd.

     In addition to the general provisions described above, certain subsidiaries
of Hutchison Whampoa Ltd. agreed to convert their VoiceStream convertible
preferred shares into VoiceStream common shares before the record date.

  The Agreements with Telephone & Data Systems, Inc.

     Telephone & Data Systems, Inc. and Deutsche Telekom entered into a
stockholder agreement containing the general provisions described above and two
letter agreements. The parties agreed that, in the event that the board of
directors of Telephone & Data Systems determines that Telephone & Data Systems
is subject to the regulations of the Investment Company Act of 1940 and
Telephone & Data Systems is unsuccessful in obtaining an exemption from such
regulations or is not eligible for an exemption, the restrictions on Telephone &
Data Systems' right to transfer VoiceStream common shares will be modified to
allow it to sell a minimum number of VoiceStream common shares that would allow
Telephone & Data Systems, with a reasonable margin of safety, to avoid being
characterized as an "investment company" under the Investment Company Act of
1940.

     In addition, Telephone & Data Systems and Deutsche Telekom agreed to
procedures concerning Deutsche Telekom's delivery of the consideration to be
paid to VoiceStream stockholders in the Deutsche Telekom/VoiceStream merger.
Deutsche Telekom agreed to take all action reasonably possible to expedite the
steps necessary to issue the Deutsche Telekom ordinary shares in the Deutsche
Telekom/VoiceStream merger and list those Deutsche Telekom shares on the
Frankfurt Stock Exchange on or promptly after the completion of the Deutsche
Telekom/VoiceStream merger. Deutsche Telekom further agreed to use its
reasonable best efforts to deliver the cash portion of the merger consideration
to the escrow agent prior to

                                       144
<PAGE>   163

or immediately after the completion of the Deutsche Telekom/VoiceStream merger
in immediately available funds and to cause the escrow agent to release the
aggregate cash consideration payable in the Deutsche Telekom/VoiceStream merger,
including the cash payable to Telephone & Data Systems, promptly upon the
registration of the increase of Deutsche Telekom share capital. If possible,
Deutsche Telekom will cause the cash consideration to be released on the date
the Deutsche Telekom/VoiceStream merger is completed or, if this is not
possible, as promptly as possible thereafter. Deutsche Telekom also agreed to
instruct the escrow agent to release the share certificates for Deutsche Telekom
ADSs and Deutsche Telekom ordinary shares to be issued in the Deutsche
Telekom/VoiceStream merger no later than one business day after registration of
the Deutsche Telekom capital increase and to use its reasonable best effects to
cause the escrow agent to deliver such certificates to Telephone & Data Systems.

THE DEUTSCHE TELEKOM INVESTMENT AGREEMENTS

     In connection with the Deutsche Telekom/VoiceStream merger agreement,
Deutsche Telekom agreed to purchase 3,906,250 shares of a new class of voting
preferred shares of VoiceStream for an aggregate purchase price of $5 billion.
This purchase was completed on September 6, 2000. We summarize below the
material terms of the new class of voting preferred shares and the agreements
entered into in connection with the issuance and sale of those shares, but this
description does not purport to describe all of the terms of such documents. The
following summary is therefore qualified in its entirety by reference to the
full text of the agreements described, copies of which have been filed as
exhibits to Deutsche Telekom's and VoiceStream's respective registration
statements and are incorporated herein by reference.

     VoiceStream Convertible Voting Preferred Shares

     On July 23, 2000, the VoiceStream board of directors authorized the
creation of a class of shares designated "Convertible Voting Preferred Stock,"
par value $0.001 per share, consisting of up to 3,906,250 shares, all of which
were issued to Deutsche Telekom under the shares subscription agreement. See
"Stock Subscription Agreement."

     Liquidation Preference.  In the event of a liquidation or dissolution of
VoiceStream, holders of shares of VoiceStream voting preferred shares will be
entitled to a liquidation preference of $1,280 per share (and no more) (subject
to adjustment for stock splits or other comparable transactions with respect to
the VoiceStream voting preferred shares) before any distribution may be made to
the holders of VoiceStream common shares or junior preferred shares.

     Conversion.  The VoiceStream voting preferred shares are not convertible
unless the Deutsche Telekom/VoiceStream merger agreement is terminated. If the
Deutsche Telekom/VoiceStream merger agreement is terminated, each VoiceStream
voting preferred share will become convertible into the number of VoiceStream
common shares equal to the aggregate liquidation preference of the VoiceStream
voting preferred shares to be converted, divided by $160 (subject to adjustment
for shares splits or other comparable transactions with respect to the
VoiceStream voting preferred shares) per share. Assuming no adjustment in the
$1280 liquidation preference or $160 purchase price, each VoiceStream voting
preferred share will therefore be convertible into eight VoiceStream common
shares or an aggregate of 31,250,000 VoiceStream common shares.

     Voting Rights.  Holders of the VoiceStream voting preferred shares are
entitled to vote together with holders of VoiceStream common shares and not as a
separate class. Each VoiceStream voting preferred share is entitled to one vote.
The affirmative vote of the holders of a majority of the outstanding VoiceStream
voting preferred shares is necessary to adopt any amendment that will change the
powers, preferences or rights of the voting preferred shares.

     Dividends.  The holders of the VoiceStream voting preferred shares are
entitled to receive dividends and other distributions made by VoiceStream on its
capital stock to the same extent and at the same rate as dividends or
distributions made in respect of VoiceStream common shares, on an
as-converted-to-common shares basis.

                                       145
<PAGE>   164

     Redemption at Option of VoiceStream.  VoiceStream may redeem the
VoiceStream voting preferred shares at any time on or after December 31, 2020 at
a price of $1,280 per share, subject to adjustment for stock splits or other
comparable transactions with respect to the VoiceStream voting preferred shares.
However, VoiceStream will not be permitted to redeem the VoiceStream voting
preferred shares if VoiceStream is insolvent, will be rendered insolvent by the
redemption, or is prohibited by law or agreement from redeeming the VoiceStream
voting preferred shares.

     Redemption at Option of Holder.  Any holder of VoiceStream voting preferred
shares may require VoiceStream to redeem all (but not less than all) of the
VoiceStream voting preferred shares owned by the holder at any time within the
six months following December 31, 2030 at a price of $1,280 per share, subject
to adjustment for stock splits or other comparable transactions with respect to
the VoiceStream voting preferred shares. However, VoiceStream will not be
permitted to redeem the VoiceStream voting preferred shares if VoiceStream is
insolvent, will be rendered insolvent by the redemption, or is prohibited by law
or agreement from redeeming the VoiceStream voting preferred shares.

     Transfer Restriction.  Unless the Deutsche Telekom/VoiceStream merger
agreement is terminated, VoiceStream voting preferred shares are only
transferable to a controlled subsidiary of the holder.

     Rank.  This new class of voting preferred shares will, with respect to
rights on liquidation or dissolution, rank senior to VoiceStream's common shares
and 2 1/2% Convertible Junior Preferred Stock and junior to any series or class
of VoiceStream's preferred shares.

     Stock Subscription Agreement

     On July 23, 2000, VoiceStream and Deutsche Telekom entered into a Stock
Subscription Agreement, under which Deutsche Telekom purchased from VoiceStream
3,906,250 newly issued shares of VoiceStream voting preferred shares for $5
billion on September 6, 2000. Deutsche Telekom's and VoiceStream's obligations
under the agreement were separate from and not conditioned upon completion of
the Deutsche Telekom/VoiceStream merger, and will remain in effect even if the
Deutsche Telekom/VoiceStream merger agreement is terminated before the Deutsche
Telekom/VoiceStream merger is completed.

     For so long as Deutsche Telekom owns any of the VoiceStream voting
preferred shares, Deutsche Telekom has agreed that if it takes any action which
would cause VoiceStream to exceed the broadband Commercial Mobile Radio Service
spectrum aggregation limits under U.S. federal communications laws, it will take
appropriate remedial action, including causing its designee (if it has one) to
resign from the VoiceStream board of directors and/or disposing of shares of
VoiceStream common shares or voting preferred shares.

     Investor Agreement

     In connection with Deutsche Telekom's agreement to purchase VoiceStream
voting preferred stock, VoiceStream and Deutsche Telekom have entered into an
Investor Agreement, dated as of July 23, 2000, which became effective on
September 6, 2000, when Deutsche Telekom first purchased such shares.

     Standstill.  Under the investor agreement, unless a standstill termination
event (described below) has occurred, until the fifth anniversary of the
investor agreement, Deutsche Telekom and its affiliates may not (subject to
certain exceptions described below):

     - acquire or agree to acquire any VoiceStream voting securities which would
       increase Deutsche Telekom's voting power above the threshold percentage
       described below;

     - solicit proxies with respect to the VoiceStream voting securities or
       become a participant in any election contest relating to the election of
       directors of VoiceStream; or

     - act in concert with any person for the purpose of effecting a transaction
       which would result in a change of control of VoiceStream.

                                       146
<PAGE>   165

     The standstill provisions described above do not apply to the Deutsche
Telekom/VoiceStream merger and do not apply in the following specific
circumstances:

     - if any person acquires or makes a bona fide offer to acquire voting
       securities of VoiceStream which, when added to the number of voting
       securities already owned by such person, exceeds or would exceed the
       threshold percentage; or

     - if Deutsche Telekom makes a tender offer for, or acquires, VoiceStream
       voting securities, with the approval of a majority of the directors of
       VoiceStream who are not Deutsche Telekom designees.

     "Standstill termination event" means the date on which the first of the
following occurs:

     - Deutsche Telekom and its affiliates beneficially own less than 5% or more
       than 90% of the outstanding voting securities of VoiceStream; or

     - the acquisition, by a party other than Deutsche Telekom or its
       affiliates, of more than 50% of the VoiceStream voting securities, a sale
       of substantially all the assets of VoiceStream or the liquidation or
       dissolution of VoiceStream.

     "Threshold percentage" means (subject to adjustment):

     - 33% from the date of the investor agreement until the second anniversary
       of the closing of the subscription agreement;

     - 36% from the second anniversary of the closing of the subscription
       agreement until the third anniversary of the closing of the subscription
       agreement; and

     - 40% from the third anniversary of the closing of the subscription
       agreement until the fifth anniversary of the closing of the subscription
       agreement.

     Transfer Restrictions.  Unless the Deutsche Telekom/VoiceStream merger
agreement is terminated before the Deutsche Telekom/VoiceStream merger is
completed, Deutsche Telekom and its affiliates may not transfer any VoiceStream
voting preferred shares. Deutsche Telekom may sell or transfer any VoiceStream
common shares it owns (including shares acquired on conversion of voting
preferred shares) as follows:

     - Deutsche Telekom may transfer its VoiceStream common shares, but not its
       rights and obligations under the investor agreement, to any buyer or
       transferee; or

     - Deutsche Telekom may transfer its VoiceStream common shares together with
       its rights and obligations under the investor agreement to any transferee
       that is more than 40% owned by Deutsche Telekom, of which Deutsche
       Telekom and its affiliates are the largest shareholder and which agrees
       to be bound by the investor agreement, or to any other transferee if a
       majority of the directors of VoiceStream who are not Deutsche Telekom
       designees approve the transfer.

     Partial Pre-emptive Rights.  If VoiceStream proposes to issue any voting
equity securities, Deutsche Telekom will have the right to purchase a portion of
those securities up to the percentage, calculated on a fully diluted basis, of
VoiceStream common shares owned by Deutsche Telekom at the time of the proposed
offering, on the terms and conditions VoiceStream proposes to offer those
securities to other persons. Deutsche Telekom's preemptive rights do not apply
to an issuance of equity securities by VoiceStream in connection with a stock
dividend, merger, employee stock option or public offering.

     Registration Rights.  VoiceStream has granted registration rights to
Deutsche Telekom with respect to any VoiceStream common shares Deutsche Telekom
acquires on conversion of the VoiceStream voting preferred shares or otherwise.
Deutsche Telekom's registration rights continue until all of its registrable
securities have been transferred to transferees who are not entitled to the
registration rights of Deutsche Telekom under the investor agreement or, if
earlier, all its remaining registrable securities are eligible to be transferred
to United States persons in the United States without registration under the
Securities Act and without being subject to volume limitations under Rule 144
under the Securities Act. If the Deutsche Telekom/VoiceStream merger agreement
is terminated, then beginning 45 days after termination Deutsche Telekom will
have the right to demand registration of its shares on up to eight occasions as
long as each

                                       147
<PAGE>   166

occasion relates to registration of shares having a minimum aggregate sales
price of $25 million. Deutsche Telekom may make no more than two demands in any
12-month period. Deutsche Telekom also has the right to an unlimited number of
piggyback registrations, subject to customary cutback provisions.

FIRST AMENDED AND RESTATED VOTING AGREEMENT

     The principal stockholders of VoiceStream are parties to an existing
agreement which governs their voting of VoiceStream securities. In connection
with Deutsche Telekom's agreement to purchase VoiceStream voting preferred
shares, the parties to the existing voting agreement and Deutsche Telekom
entered into the First Amended and Restated Voting Agreement, dated as of July
23, 2000. The amended voting agreement will become effective if Deutsche Telekom
converts all of its VoiceStream voting preferred shares into VoiceStream common
shares, which can only happen if the Deutsche Telekom/VoiceStream merger
agreement is terminated.

     The amended voting agreement will provide that the parties will agree to
vote their VoiceStream common shares for the election of a VoiceStream board of
directors consisting of 19 members, subject to adjustments, designated as
follows:

     (A) Mr. Stanton, as long as he is the chief executive officer of
         VoiceStream;

     (B) One member designated by Mr. Stanton, so long as he, or entities
         affiliated with him, beneficially owns at least 4,500,000 VoiceStream
         common shares;

     (C) Four members designated by Hutchison PCS (USA) and its affiliated
         entities, which may be increased or decreased depending upon increases
         or reductions in Hutchison PCS (USA)'s percentage ownership of
         outstanding VoiceStream common shares, including VoiceStream common
         shares issuable to Hutchison PCS (USA) upon conversion of the
         VoiceStream's 2.5% convertible junior preferred shares;

     (D) One member designated by The Goldman Sachs Group, Inc. and its
         affiliated entities, so long as the Goldman Sachs entities beneficially
         own at least 4,500,000 VoiceStream common shares;

     (E) Four members who were members of the Omnipoint board of directors prior
         to VoiceStream's acquisition of Omnipoint and who were selected by
         Omnipoint to serve during the period from the completion of the
         Omnipoint acquisition until the second annual meeting of stockholders
         of VoiceStream following the completion of VoiceStream's acquisition of
         Omnipoint. Omnipoint has designated the following persons to serve as
         directors: Douglas G. Smith, Richard L. Fields, James N. Perry, Jr. and
         James J. Ross;

     (F) One member designated by Sonera Corporation and its affiliated
         entities, subject to the approval of VoiceStream, which approval may
         not be unreasonably withheld, so long as Sonera Corporation entities
         beneficially own at least 4,500,000 shares of VoiceStream common
         shares. If Sonera Corporation beneficially owns more than 9,800,000
         shares of VoiceStream common shares and Telephone & Data Systems
         beneficially owns less than 4,500,000 shares of VoiceStream common
         shares, Sonera Corporation will be entitled to designate two directors;

     (G) One member designated by Telephone & Data Systems and its affiliated
         entities who is not affiliated with Telephone & Data Systems, subject
         to the approval of VoiceStream, which approval may not be unreasonably
         withheld, so long as the Telephone & Data Systems entities beneficially
         own at least 4,500,000 shares of VoiceStream common shares. If
         Telephone & Data Systems beneficially owns more than 9,800,000
         VoiceStream common shares and Sonera Corporation beneficially owns less
         than 4,500,000 VoiceStream common shares, Telephone & Data Systems will
         be entitled to designate two directors;

     (H) Two members designated by Deutsche Telekom and its affiliated entities,
         subject to the approval of VoiceStream, which approval may not be
         unreasonably withheld, so long as the Deutsche Telekom entities
         beneficially own at least 9,800,000 VoiceStream common shares. If
         Deutsche Telekom beneficially owns at least 4,500,000 VoiceStream
         common shares but less
                                       148
<PAGE>   167

than 9,800,000 shares of VoiceStream common stock, Deutsche Telekom will be
entitled to designate only one director;

     (I) The then President of VoiceStream;

     (J) The then Vice Chairman of VoiceStream; and

     (K) The remaining members, if any, of the board to be selected by a
         majority of the persons designated as described in (A), (B), (D), (I)
         and (J) above.

     In connection with the VoiceStream/Powertel merger, the largest of
VoiceStream's principal stockholders, including Deutsche Telekom, entered in
agreements, described in more detail below in "The Voicestream/Powertel
Transaction Documents -- VoiceStream's Agreements with Stockholders of
Powertel," providing that the stockholders who are parties to those agreements
will vote the VoiceStream common shares, or in the case of Deutsche Telekom,
voting preferred shares, they own in favor of the election to the VoiceStream
board of directors of one nominee chosen by Powertel and acceptable to
VoiceStream. These agreements will not be effective until the Deutsche
Telekom/VoiceStream merger is terminated and VoiceStream/Powertel merger is
completed.

AGREEMENTS WITH JOINT VENTURE PARTNERS OF VOICESTREAM

     In connection with the execution of the Deutsche Telekom/VoiceStream merger
agreement, Deutsche Telekom and VoiceStream entered into agreements with some of
VoiceStream's joint venture partners. We summarize the material terms of these
agreements below, but this description does not purport to describe all of their
terms and is qualified in its entirety by reference to the text of the
agreements described, copies of which have been filed as exhibits to Deutsche
Telekom's and VoiceStream's respective registration statements and are
incorporated herein by reference.

     Under agreements with two wholly-owned subsidiaries of Cook Inlet Region,
Inc., with affiliates of Providence Equity Partners Inc. and with SSPCS
Corporation, Deutsche Telekom agreed to assume on the date the Deutsche
Telekom/VoiceStream merger is completed various VoiceStream obligations relating
to Cook Inlet's, Providence's and SSPCS' existing rights to exchange certain
partnership and limited liability company interests for VoiceStream common
shares. In addition, Cook Inlet agreed that to the extent that Cook Inlet
receives VoiceStream common shares before the VoiceStream special meeting as a
result of the exercise of any exchange rights, it will agree, in a separate
voting agreement, to vote any VoiceStream common shares it acquires as a result
of this exchange in favor of the Deutsche Telekom/VoiceStream merger and not to
transfer more than 49.9% of its VoiceStream common shares until the earliest to
occur of the VoiceStream special meeting, January 1, 2001 and the termination of
the Deutsche Telekom/VoiceStream merger agreement. Providence agreed that to the
extent that Providence receives VoiceStream common shares before the VoiceStream
special meeting as a result of the exercise of its exchange right covering
321,334 VoiceStream common shares, it will agree, in a separate voting
agreement, to vote these VoiceStream shares in favor of the Deutsche
Telekom/VoiceStream merger and not to transfer more than 49.9% of such
VoiceStream common shares until the earliest of the VoiceStream special meeting,
January 1, 2001 and the termination of the Deutsche Telekom/VoiceStream merger
agreement. Each of these separate voting agreements will terminate, except with
respect to the voting agreement, upon the earliest to occur of:

     - the completion of the Deutsche Telekom/VoiceStream merger;

     - January 1, 2001; and

     - the termination of the Deutsche Telekom/VoiceStream merger agreement.

     In connection with the Deutsche Telekom/VoiceStream merger agreement,
Providence also entered into an agreement with VoiceStream and Western Wireless
amending an existing agreement under which Providence had a right to exchange
certain partnership interests for Western Wireless common shares. In the new
agreement, VoiceStream and Western Wireless agreed to purchase for $20 million
Providence's

                                       149
<PAGE>   168

right to exchange for Western Wireless common shares and granted Providence the
right to exchange its partnership interests for 321,334 VoiceStream common
shares. Providence also entered into an exchange rights agreement with
VoiceStream that amended a prior agreement pursuant to which Providence had the
right to exchange its membership interest in a certain limited liability company
into a variable number of VoiceStream common shares, based on the fair market
value of Providence's membership interest at the time of the exchange. The new
exchange rights agreement fixes the number of VoiceStream common shares
Providence would receive for its limited liability company interest at 4,000,000
VoiceStream common shares.

     In September 2000, an affiliate of Cook Inlet delivered to VoiceStream
notice of its intent to exchange with VoiceStream its membership interests in
certain joint ventures with VoiceStream for VoiceStream common shares. On the
same day, another affiliate of Cook Inlet delivered to VoiceStream notice of its
intent to exchange a certain partnership interest with VoiceStream for cash.
VoiceStream and the two Cook Inlet affiliates are currently seeking FCC approval
of these exchanges.

   SUMMARY OF DEUTSCHE TELEKOM/POWERTEL AND VOICESTREAM/POWERTEL TRANSACTION
                                   DOCUMENTS

THE DEUTSCHE TELEKOM/POWERTEL MERGER AGREEMENT

     This section of the proxy statement/prospectus is a summary of the
principal provisions of the Deutsche Telekom/Powertel merger agreement. This
summary does not purport to be complete and is qualified in its entirety by
reference to the Deutsche Telekom/Powertel merger agreement, a copy of which is
attached as Annex B to this proxy statement/prospectus and incorporated herein
by reference. Powertel stockholders are urged to read the Deutsche
Telekom/Powertel merger agreement in its entirety, as it is the legal document
governing the Deutsche Telekom/Powertel merger.

     The Deutsche Telekom/Powertel Merger

     A Delaware corporation formed by Deutsche Telekom will merge with and into
Powertel, and, as a result, Powertel will become a wholly-owned subsidiary of
Deutsche Telekom.

     Effective Time and Timing of Closing

     The Deutsche Telekom/Powertel merger will be completed and become effective
when Powertel files a certificate of merger with the Secretary of State of the
State of Delaware or at such later time as is specified in the certificate of
merger in accordance with Delaware law. We expect the Deutsche Telekom/Powertel
merger to become effective on the same day as the closing of the Deutsche
Telekom/ Powertel merger, which will take place on the fifth business day after
the conditions to the Deutsche Telekom/Powertel merger have been satisfied or
waived, or on such other date as Deutsche Telekom and Powertel may agree. In
addition, on the closing date of the Deutsche Telekom/Powertel merger or as soon
as possible after the closing date, Deutsche Telekom and Powertel will undertake
a number of additional actions, including making filings with regulatory and
stock exchange authorities, necessary to permit the issuance of the merger
consideration under German laws and regulations and the rules of the Frankfurt
Stock Exchange.

     Consideration to be Received in the Deutsche Telekom/Powertel Merger

     In the Deutsche Telekom/Powertel merger, holders of Powertel common shares
will receive 2.6353 Deutsche Telekom shares for each of their Powertel common
shares. We refer to the number of Deutsche Telekom shares to be received for
each Powertel common share as the "common share exchange ratio". Holders of
Powertel's Series A preferred shares and Series B preferred shares will receive
121.9294 Deutsche Telekom shares for each of their Powertel Series A preferred
shares and Series B preferred shares. Holders of Powertel's Series D preferred
shares will receive 93.0106 Deutsche Telekom shares for each of their Powertel
Series D preferred shares. Holders of Powertel's Series E preferred shares and
Series F preferred shares will receive 179.5979 Deutsche Telekom shares for each
of their Powertel Series E preferred shares and Series F preferred shares, plus
a number of Deutsche Telekom shares equal to the product of (1) the number of
Powertel common shares representing accrued or declared but unpaid dividends on
each Powertel Series E or Series F preferred share, calculated as if the date of
the completion of the Deutsche Telekom/Powertel merger were a dividend payment
date, and (2) the common share exchange ratio. All of the exchange ratios
described above are subject to adjustment as described below.

     We refer to the number of Deutsche Telekom shares a Powertel stockholder,
optionholder or warrantholder will receive in the Deutsche Telekom/Powertel
merger in exchange for its Powertel common shares, preferred shares, warrants or
options, as the case may be, as an "exchange ratio". The exchange ratios
applicable to the outstanding Powertel preferred shares, options and warrants
are based on the number of Deutsche Telekom shares a holder of those Powertel
preferred shares, options or warrants would have received in the Deutsche
Telekom/Powertel merger had such holder converted its Powertel preferred shares
into Powertel common shares or exercised its Powertel options or warrants for
Powertel common shares on the date of the Deutsche Telekom/Powertel merger
agreement. As is discussed more
                                       151
<PAGE>   170

fully below, the exchange ratio with respect to a particular class of Powertel
shares, options or warrants is a fixed number of Deutsche Telekom shares, but is
subject to adjustment.

     You will receive Deutsche Telekom shares in the form of Deutsche Telekom
ADSs, which trade principally on the NYSE under the symbol "DT", or, if you
prefer, in the form of Deutsche Telekom ordinary shares, which are traded on the
Frankfurt Stock Exchange under the symbol "DTE".

     Adjustment to Exchange Ratios.  Each exchange ratio was determined assuming
that at the time the Deutsche Telekom/Powertel merger is completed, the
aggregate number of Powertel common shares outstanding on a fully diluted basis
and adjusted for specific commitments to issue Powertel common shares (excluding
Powertel common shares issuable as dividends after August 26, 2000 on Series E
preferred shares and Series F preferred shares), an aggregate number of Powertel
shares we call the "adjusted fully diluted shares amount," will not exceed the
"maximum share amount." The maximum share amount is 55,742,000, which may be
reduced as set forth in the Deutsche Telekom/Powertel merger agreement. Each
exchange ratio is subject to adjustment in the event that the adjusted fully
diluted shares amount as of the date the Deutsche Telekom/Powertel merger is
completed exceeds the maximum share amount. In the event of an adjustment, the
effect will be to cap the number of Deutsche Telekom shares that will be issued
in the Deutsche Telekom/Powertel merger and to reduce the number of Deutsche
Telekom shares to be received by Powertel stockholders, optionholder and
warrantholder in the Deutsche Telekom/Powertel merger in exchange for each of
their Powertel common shares or Powertel preferred shares, as the case may be.
We illustrate below how the adjustment mechanism will be used.

     - Step 1. Derive the adjusted fully diluted shares amount:  The adjusted
       fully diluted shares amount is the sum of the number of outstanding
       Powertel common shares, less the number of shares issuable as dividends
       after August 26, 2000 on the Series E preferred shares and Series F
       preferred shares, plus

        - the number of Powertel common shares issuable upon conversion of the
          Powertel preferred shares;

        - the number of Powertel common shares issuable pursuant to the exercise
          of Powertel stock options and Powertel warrants;

        - the number of Powertel common shares issuable pursuant to Powertel
          restricted stock awards;

        - the number of Powertel common shares issuable pursuant to the exercise
          of the put rights held by Sonera Holding B.V. and Eliska Wireless
          Investors, unless such rights have been terminated;

        - the number of Powertel common shares issuable pursuant to the stock
          purchase agreement between Powertel and Sonera Holding B.V., unless
          this stock purchase agreement has been terminated;

        - the number of Powertel common shares issuable pursuant to the exercise
          of any stock appreciation rights, phantom stock rights or other
          contractual rights the value of which is determined in whole or in
          part by the value of any Powertel shares; and

        - the number of any other Powertel common shares outstanding and
          Powertel common shares issuable pursuant to any other securities
          outstanding, which are convertible into, or exercisable or
          exchangeable for, Powertel common shares.

     - Step 2. Derive the adjustment factor: The adjustment factor is a fraction
       (a) the numerator of which is 55,742,000, as it may be adjusted in
       accordance with the Deutsche Telekom/Powertel merger agreement, and (b)
       the denominator of which is the adjusted fully diluted shares amount.

     - Step 3. Derive the adjusted exchange ratios:  Each exchange ratio will be
       reduced by multiplying such exchange ratio by the adjustment factor.

                                       152
<PAGE>   171

     - Step 4. Derive the adjusted stock consideration:  Each outstanding
       Powertel common share, each Powertel common share issuable upon the
       exercise of outstanding Powertel warrants and Powertel stock options and
       each Powertel preferred share will then be converted in the Deutsche
       Telekom/Powertel merger into the right to receive a number of Deutsche
       Telekom shares equal to the adjusted exchange ratio calculated pursuant
       to Step 3.

     Example.  If the adjusted fully diluted shares amount exceeds 55,742,000,
as it may be adjusted in accordance with the Deutsche Telekom/Powertel merger
agreement, we would calculate the number of Deutsche Telekom shares into which
each Powertel share will be converted as illustrated above. Assuming that the
adjusted fully diluted shares amount is 55,795,000, then the adjustment factor
would be 0.9991. If you own 100 Powertel common shares under these
circumstances, you would receive the amount of Deutsche Telekom shares equal to
2.6353 multiplied by 0.9991, multiplied by the number of shares you hold, or
100, for a total of 263 shares, plus cash for 0.29 of a Deutsche Telekom share.

     Powertel stockholders will not receive fractional Deutsche Telekom shares
and instead will receive a cash payment representing the net proceeds from the
sale of the fractional Deutsche Telekom shares. The treatment of fractional
Deutsche Telekom shares is described below in "-- Election and Exchange of
Certificates Representing Powertel Shares".

     Other Potential Adjustments.  The amount and form of the merger
consideration will be adjusted in the event that before the completion of the
Deutsche Telekom/Powertel merger:

     - a reclassification, split-up, stock-split, reverse stock-split, stock
       dividend, stock combination, recapitalization, redenomination of share
       capital, merger or similar transaction or an exchange offer causes a
       change to the Deutsche Telekom ordinary shares outstanding, or the number
       of Deutsche Telekom ordinary shares represented by a Deutsche Telekom ADS
       is changed; or

     - all of the outstanding Deutsche Telekom ordinary shares, or more than 80%
       of the outstanding Deutsche Telekom ordinary shares pursuant to an
       exchange offer for all outstanding Deutsche Telekom shares, are changed
       into or exchanged for a different number or kind of shares of Deutsche
       Telekom, or into shares of another entity owning more than 80% of the
       Deutsche Telekom ordinary shares.

     For example, if prior to completion of the Deutsche Telekom/Powertel
merger, Deutsche Telekom, in order to facilitate future acquisitions, were to
establish a new German holding company that acquired through an exchange offer
more than 80% of the outstanding Deutsche Telekom shares, holders of Powertel
common shares would receive shares of the new holding company instead of
Deutsche Telekom shares in the Deutsche Telekom/Powertel merger.

     Treatment of Powertel Warrants

     If any of the warrants granted pursuant to the warrant agreement dated
February 7, 1996 between Powertel and Bankers Trust Company, as warrant agent,
have not been exercised before the Deutsche Telekom/Powertel merger becomes
effective and a holder of warrants becomes entitled to Deutsche Telekom ordinary
shares at any time after the Deutsche Telekom/Powertel merger, any Deutsche
Telekom ordinary shares to which such holder becomes entitled will be issued
from a special trust established for the benefit of such warrant holders and any
cash to which such holder becomes entitled will be paid by Deutsche Telekom.

     Treatment of Eliska Put Rights

     If Sonera Holding B.V. or Eliska Wireless Investors (who are referred to as
the Eliska Partners) receive Powertel common shares before the Deutsche
Telekom/Powertel merger is completed as a result of exercising their rights to
exchange interests in Eliska Wireless Ventures for Powertel common shares, such
Eliska Partners will have all the rights with respect to those Powertel common
shares which a Powertel stockholder has.

                                       153
<PAGE>   172

     To the extent that any Eliska Partners has not received Powertel common
shares before the Deutsche Telekom/Powertel merger is completed in respect of
their exchange rights, those Eliska Partners will be entitled to receive the
consideration that they are entitled to receive pursuant to their exchange
rights.

     To the extent that any of the Eliska Partners are entitled to receive
Deutsche Telekom shares on or after the date the Deutsche Telekom/Powertel
merger is completed, the Deutsche Telekom shares will be delivered from a
special trust established for the benefit of such Eliska Partners, and any cash
to which such Eliska Partners become entitled will be paid by Deutsche Telekom.

     Election and Exchange of Certificates Representing Powertel Shares

     Deutsche Telekom will appoint an escrow agent to serve in connection with
the Deutsche Telekom/Powertel merger. Shortly after the Deutsche
Telekom/Powertel merger is completed, Deutsche Telekom and Powertel intend to
mail, or cause the escrow agent to mail, to each registered holder of Powertel
common shares and Powertel preferred shares a letter of transmittal which the
holder must properly complete and deliver to the escrow agent with the holder's
stock certificates.

     The escrow agent will exchange certificates representing Powertel shares
for American depositary receipts representing Deutsche Telekom ADSs or, if a
Powertel stockholder properly elects, certificates representing Deutsche Telekom
ordinary shares. The letter of transmittal mailed to Powertel stockholders will
contain an "ordinary share election" form which can be used by a stockholder to
elect to receive merger consideration in Deutsche Telekom ordinary shares.

     After a record holder of Powertel shares delivers certificates for those
shares and a properly completed letter of transmittal to the escrow agent, the
escrow agent will deliver to the holder:

     - the number of whole Deutsche Telekom ADSs or Deutsche Telekom ordinary
       shares included in the merger consideration in respect of such Powertel
       shares; and

     - a check in the amount (after giving effect to any required tax
       withholdings) of (1) any cash in lieu of any fractional interest in
       Deutsche Telekom ADSs or Deutsche Telekom ordinary shares on the terms
       described below, plus (2) any cash dividends or other distributions that
       the holder has the right to receive, including dividends or other
       distributions payable with respect to the holders of Deutsche Telekom
       ADSs or Deutsche Telekom ordinary shares with a record date after the
       completion of the Deutsche Telekom/Powertel merger and a payment date on
       or before the date the holder properly delivers Powertel stock
       certificates to the escrow agent.

     The escrow agent will not deliver fractional Deutsche Telekom ADSs or
fractional Deutsche Telekom ordinary shares in connection with the Deutsche
Telekom/Powertel merger. Instead, each holder of Powertel shares exchanged in
the Deutsche Telekom/Powertel merger who would otherwise have received a
fraction of a Deutsche Telekom ADS or Deutsche Telekom ordinary share will be
entitled to receive a cash payment representing that holder's proportionate
interest in the net proceeds from the sale by the escrow agent of the aggregate
of the fractions of Deutsche Telekom ADSs and Deutsche Telekom ordinary shares
that would otherwise be issued. The escrow agent will execute the sale of those
Deutsche Telekom ADSs and Deutsche Telekom ordinary shares on the NYSE and the
Frankfurt Stock Exchange, respectively. Deutsche Telekom will pay all
commissions, transfer taxes and out-of-pocket costs, including the expenses and
compensation of the escrow agent, incurred in connection with the sale of the
Deutsche Telekom ADSs and Deutsche Telekom ordinary shares.

     Powertel shares that are surrendered to the escrow agent will be canceled.
No interest will be paid or accrued on any amount payable to holders of Powertel
shares. In addition, no holder of Powertel shares will receive any dividends or
other distributions with respect to Deutsche Telekom ADSs or Deutsche Telekom
ordinary shares to which the holder is entitled under the Deutsche
Telekom/Powertel merger agreement until that holder's Powertel stock certificate
is surrendered to the escrow agent with a properly completed letter of
transmittal.

                                       154
<PAGE>   173

     If any Deutsche Telekom ADSs or Deutsche Telekom ordinary shares are to be
delivered to a person other than the registered holder of the Powertel shares
represented by the certificates surrendered to the escrow agent:

     - those Powertel stock certificates must be properly endorsed or otherwise
       be in proper form for transfer; and

     - the person requesting the delivery must pay to the escrow agent any
       transfer or other taxes required as a result of delivery to a person
       other than the registered holder, or establish to the satisfaction of the
       escrow agent that such tax has been paid or is not payable.

     Treatment of Powertel Options and Restricted Stock

     Powertel Options.  If the Deutsche Telekom/Powertel merger is completed,
each outstanding Powertel stock option will be converted into an option to
acquire, from a trust established for the benefit of holders of Powertel stock
options, that number of Deutsche Telekom shares determined by multiplying the
maximum number of Powertel common shares subject to the Powertel stock option by
the common share exchange ratio, rounded if necessary to the nearest whole
Deutsche Telekom ordinary share and subject to adjustment as described above
under "-- Consideration to be Received in the Deutsche Telekom/Powertel Merger."
The exercise price per Deutsche Telekom ordinary share for each of these options
will be the exercise price per Powertel common share applicable to that option
immediately prior to the completion of the Deutsche Telekom/Powertel merger
divided by the common share exchange ratio. The replacement options will
generally have the same terms and conditions as were applicable under the
Powertel option plans.

     Powertel Restricted Stock.  At the time the Deutsche Telekom/Powertel
merger is completed, the Powertel restricted stock plan will terminate and any
unvested Powertel restricted stock awards will become fully vested, except as
otherwise provided in the individual restricted stock award agreements.

     Dissenting Shares

     If appraisal rights for any Powertel preferred shares are perfected by any
holder of preferred shares, then those shares will be treated as described under
"The Deutsche Telekom/Powertel Merger -- Appraisal Rights."

     Covenants of Deutsche Telekom.  Except as contemplated by the Deutsche

Deutsche Telekom/Powertel merger is completed, Deutsche Telekom and its
subsidiaries will not do any of the following without Powertel's prior written
consent:

     - except for the purpose of using or increasing Deutsche Telekom's
       authorized capital or as necessary for the conduct of its business, amend
       or propose to amend the Memorandum and Articles of Association or

       document of Deutsche Telekom in any manner that would be adverse to
       Powertel or its stockholders;

       Deutsche Telekom/Powertel merger from qualifying as a reorganization
       under Section 368(a) of the U.S. tax code or cause Powertel stockholders
       to recognize gain in the Deutsche Telekom/Powertel merger under Section
       367(a)(1) of the U.S. tax code; or

       affect or materially adversely delay the ability of the parties to obtain
       any required regulatory approval or to complete the transactions
       contemplated by the Deutsche Telekom/Powertel merger agreement.

            - Important Exception:  Deutsche Telekom may make acquisitions as
              long as the acquisitions, individually or in the aggregate, are
              not reasonably likely to prevent the consummation of the Deutsche
              Telekom/Powertel merger.

     Offers for Alternative Transactions

     Powertel has agreed not to, has agreed not to permit any of its
subsidiaries to, has agreed not to authorize or permit any of its or their
respective officers, directors or employees to, and has agreed to use its
reasonable efforts to cause its advisors and representatives not to:

     - solicit, initiate or knowingly encourage, or knowingly take any other
       action designed to facilitate, any alternative transaction, which we
       define below, to the Deutsche Telekom/Powertel merger; or

     - continue or participate in any discussions or negotiations regarding any
       alternative transaction to the Deutsche Telekom/Powertel merger.

     However, if at any time before Powertel stockholders approve the Deutsche
Telekom/Powertel merger, Powertel receives an unsolicited proposal for an
alternative transaction, then Powertel may, after giving Deutsche Telekom three
business days advance notice:

     (1) furnish information with respect to Powertel pursuant to a
         confidentiality agreement substantially similar to the confidentiality
         agreement in place between Powertel and Deutsche Telekom; and

     (2) engage in discussions and negotiations with the persons that made such
         proposal;

but only if:

     (A) the Powertel board of directors has determined in good faith, after
         receiving advice from outside counsel, that providing information to
         the third party or participating in negotiations or discussions could
         be reasonably expected to result in a superior proposal, which we
         define below, being made; and

     (B) Powertel is not otherwise in breach of its obligations described above
         not to solicit or engage in discussions regarding an alternative
         transaction.

  Important Definitions:

     "alternative transaction" means any of the following:

     - a transaction or series of transactions in which any third party would
       acquire, directly or indirectly, beneficial ownership of more than 20% of
       the outstanding Powertel shares or pursuant to a tender offer or exchange
       offer;

     - any acquisition of or business combination with Powertel or any of its
       significant subsidiaries, by a merger or other business combination; or

     - any transaction in which any third party would acquire, directly or
       indirectly, control of assets of Powertel or any of its subsidiaries for
       consideration equal to 20% or more of the fair market value of all of the
       outstanding Powertel shares on August 26, 2000.

An alternative transaction does not include the acquisition of Powertel by
VoiceStream pursuant to the VoiceStream/Powertel merger agreement.

     "superior proposal" means any proposal made by a third party to enter into
an alternative transaction which the Powertel board of directors determines in
its good faith judgment, based on, among other things, the advice of a financial
advisor of nationally recognized reputation, to be more favorable to Powertel's
stockholders than the Deutsche Telekom/Powertel merger taking into account all
relevant factors (including whether, in the good faith judgment of the Powertel
board of directors, the third party is reasonably able to finance the proposed
transaction).

     Powertel also has agreed to notify Deutsche Telekom promptly of any request
for information or of any proposal in connection with an alternative
transaction, including the material terms of the request or proposal and the
identity of the person making it, and Powertel has agreed to keep Deutsche
Telekom informed of the status of any alternative transaction. In addition,
Powertel agreed to cease any activities, discussions or negotiations with
respect to an alternative transaction that existed at the time the Deutsche
Telecom/Powertel merger agreement was signed.

     Powertel Board of Directors' Recommendation

     The Deutsche Telekom/Powertel merger agreement requires the Powertel board
of directors:

     (1) to recommend that the Powertel stockholders approve the Deutsche
         Telekom/Powertel merger agreement;

     (2) not to withdraw, modify or qualify, or to propose publicly to withdraw,
         modify or qualify, its recommendation in a manner adverse to Deutsche
         Telekom;

     (3) not to approve or recommend, or to propose publicly to approve or
         recommend, any alternative transaction; and

                                       160
<PAGE>   179

     (4) not to cause Powertel to agree to engage in any alternative
         transactions.

     However, if the Powertel board of directors receives a superior proposal
before Powertel stockholders approve the Deutsche Telekom/Powertel merger, the
Powertel board of directors may inform Powertel stockholders that it no longer
recommends approval of the Deutsche Telekom/Powertel merger, if:

     - Powertel sends Deutsche Telekom written notice that Powertel has received
       a superior proposal, which states the terms of the superior proposal and
       identifies the proposers, and that Powertel intends to change its
       recommendation regarding the Deutsche Telekom/Powertel merger; and

     - five business days have passed since Deutsche Telekom received the
       notice. In addition, Powertel must give Deutsche Telekom reasonable
       opportunity to make adjustments in the terms of the Deutsche
       Telekom/Powertel merger agreement that would enable the Powertel board of
       directors to maintain its recommendation to approve the Deutsche
       Telekom/Powertel merger.

     The Deutsche Telekom/Powertel merger agreement also permits Powertel to
take and disclose to Powertel stockholders a position contemplated by Rule 14d-9
or Rule 14e-2(a) under the Exchange Act or to make any other disclosure to
Powertel stockholders if, in the good faith judgment of the Powertel board of
directors, after receiving advice from outside counsel, failure to disclose
would result in a reasonable likelihood that the Powertel board of directors
would breach its duties to Powertel stockholders under applicable law.

     Submission of Deutsche Telekom/Powertel Merger Agreement to Stockholder
Vote.  The Deutsche Telekom/Powertel merger agreement requires Powertel to
submit the Deutsche Telekom/Powertel merger agreement to a stockholder vote at
the Powertel special meeting even if the Powertel board of directors no longer
recommends approval of the Deutsche Telekom/Powertel merger.

     Additional Agreements

     The Deutsche Telekom/Powertel merger agreement contains a number of other
covenants and agreements by or between Powertel and Deutsche Telekom on subjects
including:

     - timely filing accurate financial statements with the SEC by Powertel or
       Deutsche Telekom after the signing of the Deutsche Telekom/Powertel
       merger agreement;

     - notification of facts, events or circumstances that are reasonably likely
       to cause any representation or warranty contained in the Deutsche
       Telekom/Powertel merger agreement to become untrue or inaccurate or to
       result in a material adverse effect on either Powertel or Deutsche
       Telekom;

     - permitting reasonable access to each other's information, employees and
       properties;

     - public announcements relating to the transactions contemplated by the
       Deutsche Telekom/Powertel merger agreement;

     - using reasonable best efforts to obtain necessary tax opinions and
       representation letters;

     - using reasonable best efforts to cause the Deutsche Telekom/Powertel
       merger to qualify as a reorganization within the meaning of Section
       368(a) of the U.S. tax code and to avoid gain recognition to the
       stockholders of Powertel in the Deutsche Telekom/Powertel merger under
       Section 367(a)(1) of the U.S. tax code;

     - using reasonable efforts to take appropriate actions to attempt to cause
       the warrants outstanding pursuant to the warrant agreement dated February
       6, 1996 between Powertel and Bankers Trust Company, as warrant agent, to
       be exercised in full prior to the completion of the Deutsche
       Telekom/Powertel merger, including by reducing their exercise price to
       the extent agreed to by Deutsche Telekom and Powertel; and

     - avoidance of actions that would cause the transactions contemplated by
       the Deutsche Telekom/ Powertel merger agreement to be subject to certain
       takeover laws.

                                       161
<PAGE>   180

     In addition, Deutsche Telekom has agreed to take all steps necessary to
cause the new Deutsche Telekom ADSs and Deutsche Telekom ordinary shares to
become listed on the NYSE and the Frankfurt Stock Exchange, respectively.

     Deutsche Telekom has additionally agreed to certain limitations on its
ability to transfer any VoiceStream shares it owns or acquires, and to vote its
VoiceStream shares in favor of the VoiceStream/Powertel merger. Specifically,
Deutsche Telekom has agreed that it will not transfer any VoiceStream common
shares, preferred shares or common share equivalents, except pursuant to the
Deutsche Telekom/VoiceStream merger agreement, to affiliates of Deutsche Telekom
agreeing to be bound by the same voting agreement and transfer restrictions and
by operation of law. These transfer limitations apply until the later of January
1, 2001 and the date of the VoiceStream special meeting called for the purpose
of approving the VoiceStream/Powertel merger.

     Powertel has agreed to the termination of certain existing stockholder
agreements.

     Senior Discount Notes and Senior Notes

     Deutsche Telekom has also agreed to cause the surviving corporation to

     Powertel and Deutsche Telekom have agreed to:

       Deutsche Telekom/Powertel merger agreement;

     - obtain in a timely manner all necessary consents, permits, approvals or
       waivers, from any governmental or regulatory authority which are
       necessary for the completion of the Deutsche Telekom/Powertel merger;

     - promptly prepare and file all required notifications under U.S. antitrust
       laws and to comply with any requests for additional information, and
       obtain termination of any applicable waiting periods or obtain any
       required approvals as promptly as practicable; and

     - take all actions within its control necessary to obtain any required
       regulatory approvals.

     - Important Exception:  Neither Deutsche Telekom nor its subsidiaries is
       required, nor shall Powertel or its subsidiaries be permitted, to divest
       or hold separate or otherwise take or commit to take any action that
       limits its freedom of action with respect to Powertel, Deutsche Telekom,
       VoiceStream or any of their subsidiaries, any material portion of their
       assets or any of their businesses or product lines.

     However, in connection with any filing or submission required or action to
be taken to consummate the Deutsche Telekom/Powertel merger, Powertel shall not,
without Deutsche Telekom's prior written consent, commit to divest any assets of
the business of Powertel and its subsidiaries if such divested assets and/or
businesses are material to the assets or profitability of Powertel and its
subsidiaries taken as a whole.

     Powertel and Deutsche Telekom also have agreed to:

     - cooperate with each other to respond to inquiries by governmental or

<PAGE>   181

       meetings and conferences, or to review and approve any filing or other
       written submission;

     - cooperate to eliminate or reduce to the extent possible any illegality,
       forfeiture or loss on the part of Deutsche Telekom, Powertel or their
       respective subsidiaries that may result from the completion of the
       Deutsche Telekom/Powertel merger; and

     - cooperate with each other and to do all things reasonably requested by
       the other party in order to facilitate any financing, acquisition or
       capital markets transaction or registration to be entered into or made by
       either party.

     Indemnification and Insurance

     The surviving corporation of the Deutsche Telekom/Powertel merger is
required by the Deutsche Telekom/Powertel merger agreement to maintain in effect
the current provisions regarding indemnification of officers and directors
contained in the charter and bylaws and any indemnification agreements of
Powertel and each of its subsidiaries.

     Prior to the completion of the Deutsche Telekom/Powertel merger, Powertel
has the right, subject to Deutsche Telekom's prior written approval, to obtain a
"tail" coverage directors' and officers' liability insurance policy providing
coverage in amounts and on terms consistent with Powertel's existing insurance
for a period of six years after the completion of the Deutsche Telekom/Powertel
merger. If Powertel does not obtain this insurance prior to the completion of
the Deutsche Telekom/Powertel merger, Deutsche Telekom has agreed to cause the
surviving corporation to continue to provide directors' and officers' liability
insurance for a period of six years after the completion of the Deutsche
Telekom/VoiceStream merger. However, the surviving corporation is not required
to expend in any year an amount in excess of 250% of the last annual premium
paid by Powertel prior to August 26, 2000. If the aggregate expenditure on
coverage exceeds that amount, the surviving corporation will purchase as much
insurance as can be obtained for that amount.

     Employee Benefits

     Following the completion of the Deutsche Telekom/Powertel merger, Deutsche
Telekom will take all necessary action so that each current and former Powertel
employee who was eligible to participate in a Powertel benefit plan before the
Deutsche Telekom/Powertel merger will be eligible to participate in a
corresponding employee benefit plan maintained by Deutsche Telekom or its
subsidiaries after the Deutsche Telekom/Powertel merger. The Deutsche
Telekom/Powertel merger agreement also specifies the treatment of pre-existing
conditions, exclusions and waiting periods with respect to current and former
employees of Powertel and its subsidiaries under any welfare or fringe benefit
plans of Deutsche Telekom in which such employees and former employees
participate in after completion of the Deutsche Telekom/Powertel merger.

       under the severance plan will be reduced by any payments received by the
       affected employee under the cash bonus, retention bonus or incentive
       bonus plans described above. To obtain benefits under this plan, an
       employee must agree to release the surviving corporation from all claims
       against Powertel, Deutsche Telekom and VoiceStream; and

     - Powertel will be allowed to issue an aggregate of 575,000 options prior

       employees in yearly performance grants, to DiGiPH employees that become
       Powertel employees and in connection with offers of employment
       outstanding as of August 26, 2000. Employees whose employment is
       terminated due to job elimination resulting from the merger will receive
       change of control accelerated vesting of their options if their job is
       eliminated with 18 months of the completion of the Deutsche
       Telekom/Powertel merger. Individuals receiving change of control vesting
       will not be eligible for payments under the cash bonus, retention bonus
       or incentive bonus plans but will be eligible for severance payments,
       subject to certain reductions.

     Termination and Termination Fee

    Automatic Termination.  The Deutsche Telekom/Powertel merger agreement will
    terminate automatically upon the termination of the Deutsche

    Right to Terminate.  The Deutsche Telekom/Powertel merger agreement may be
    terminated at any time before the completion of the Deutsche
    Telekom/Powertel merger in any of the following ways:

     - by mutual written consent;

     - by either Deutsche Telekom or Powertel:

        -- if the Deutsche Telekom/Powertel merger has not been completed on or
           before December 31, 2001 (unless the party seeking to terminate the
           Deutsche Telekom/Powertel merger has failed to fulfill its
           obligations under the Deutsche Telekom/Powertel merger agreement and
           such failure has caused the delay);

        -- if the Deutsche Telekom/Powertel merger is permanently restrained,
           enjoined or otherwise prohibited by a governmental order, decree,
           ruling or other action, and the order, decree, ruling or other action
           has become final and nonappealable;

        -- at any time that is not less than 15 days after any statute, rule,
           decree, order or injunction has been enacted, entered, promulgated or
           enforced by any governmental or regulatory authority (other than a
           court) that has the effect of making any of the closing conditions
           described above under "-- Closing Conditions -- Legality" and
           "-- Closing Conditions -- Competition Law Approvals" and "Regulatory
           Approvals -- Regulatory Approvals Required for the Deutsche
           Telekom/Powertel Merger" incapable of being satisfied by December 31,

        -- if Powertel's stockholders fail to approve the Deutsche
           Telekom/Powertel merger at the Powertel special meeting.

     - by Powertel:

        -- if a condition to the obligations of Powertel to complete the
           Deutsche Telekom/Powertel merger is or becomes incapable of being
           satisfied prior to December 31, 2001; or

        -- if Deutsche Telekom shall have breached or failed to perform in any
           material respect any of its representations, warranties, covenants or
           other agreements contained in the Deutsche Telekom/Powertel merger
           agreement, which breach or failure cannot be cured by Deutsche
           Telekom before December 31, 2001, or, if curable, is not cured by
           Deutsche Telekom within 30 days of receipt by Deutsche Telekom of
           notice of the breach from Powertel and such breach or failure renders
           any condition to the obligation of Powertel to complete the Deutsche
           Telekom/Powertel merger incapable of being satisfied prior to
           December 31, 2001.

     - by Deutsche Telekom:

        -- if Powertel shall have breached or failed to perform in any material
           respect any of its representations, warranties, covenants or other
           agreements contained in the Deutsche Telekom/Powertel merger
           agreement, which breach or failure cannot be cured by Powertel before
           December 31, 2001, or, if curable, is not cured by Powertel within 30
           days of receipt by Powertel of notice of the breach from Deutsche
           Telekom and such breach or failure renders any condition to the
           obligations of Deutsche Telekom to complete the Deutsche
           Telekom/Powertel merger incapable of being satisfied prior to
           December 31, 2001;

        -- if a condition to the obligations of Deutsche Telekom to complete the
           Deutsche Telekom/Powertel merger is or becomes incapable of being
           satisfied prior to December 31, 2001;

        -- if, in connection with the grant of any required regulatory approval
           relating to the Deutsche Telekom/Powertel merger, Powertel, Deutsche
           Telekom, VoiceStream or any of their subsidiaries shall be required
           to divest or hold separate or otherwise take any action that limits
           its freedom of action with respect to Powertel, Deutsche Telekom,
           VoiceStream or any of their subsidiaries or any material assets of
           Powertel, Deutsche Telekom, VoiceStream or any of their subsidiaries,
           or any of the businesses, product lines or assets of Powertel,
           Deutsche Telekom, VoiceStream or any of their subsidiaries and such
           order, decree, ruling, or other action shall have become final and
           nonappealable; or

        -- if the VoiceStream/Powertel merger agreement has been terminated at
           any time prior to the termination or consummation of the Deutsche
           Telekom/VoiceStream merger agreement.

  Termination Fees Payable to Deutsche Telekom.  Powertel has agreed to pay
Deutsche Telekom a termination fee of $150 million plus expenses not to exceed
$10 million if all three of the following events occur:

        (1) after August 26, 2000 and before the Powertel special meeting a
            proposal for certain types of alternative transactions is announced
            or publicly disclosed and not withdrawn;

        (2) the Deutsche Telekom/Powertel merger agreement is terminated by
            either party because Powertel's stockholders do not approve the
            Deutsche Telekom/Powertel merger at the Powertel special meeting;
            and

        (3) within six months after the termination of the Deutsche
            Telekom/Powertel merger agreement, Powertel enters into a definitive
            agreement with any third party with respect to certain types of
            alternative transactions.

       In that circumstance, Powertel would pay to Deutsche Telekom the
       termination fee no later than one business day after the signing of the
       definitive agreement with the third party.
                                       168
<PAGE>   187

     In the event Powertel is also obligated to pay a termination fee pursuant
to the VoiceStream/Powertel merger agreement, Powertel shall instead pay each of
Deutsche Telekom and VoiceStream $75 million plus expenses not to exceed $10
million. For purposes of determining whether a termination fee is payable, the
term "alternative transaction" has the meaning described above under "-- Offers
for Alternative Transactions," except that the 20% thresholds are treated as 50%
thresholds, and mergers or business combinations in which Powertel stockholders
would continue to hold at least 65% of the outstanding stock of the entity
surviving the transaction are not considered to be "alternative transactions".

     Expenses

     Whether or not the Deutsche Telekom/Powertel merger is completed, all costs
and expenses incurred in connection with the Deutsche Telekom/Powertel merger
and the Deutsche Telekom/Powertel merger agreement will be paid by the party
incurring the expense, except that Deutsche Telekom, VoiceStream and Powertel
will share equally the costs and expenses of printing the Form F-4 registration
statement and this document, and Deutsche Telekom and Powertel will each share
equally the costs and expenses of any SEC filing fees with respect to the
Deutsche Telekom/Powertel merger. Deutsche Telekom, VoiceStream and Powertel
have shared the costs and expenses of the filing fees paid under the HSR Act.

     Amendment; Waiver; Assignment

     Powertel, Deutsche Telekom and merger subsidiary may amend the Deutsche
Telekom/Powertel merger agreement by written agreement prior to completion of
the Deutsche Telekom/Powertel merger, but after Powertel's stockholders have
approved the Deutsche Telekom/Powertel merger agreement, no amendment may be
made which by law requires further stockholder approval without such approval
being obtained.

     At any time before the Deutsche Telekom/Powertel merger is completed,
Powertel, Deutsche Telekom and merger subsidiary may (1) extend the time for the
performance of any of the obligations or other acts required by the Deutsche
Telekom/Powertel merger agreement, (2) waive any inaccuracies in the
representations and warranties contained in the Deutsche Telekom/Powertel merger
agreement or any document required to be delivered pursuant to the Deutsche
Telekom/Powertel merger agreement and (3) waive compliance with any of the
agreements or conditions contained in the Deutsche Telekom/Powertel merger
agreement.

     Deutsche Telekom, Powertel and merger subsidiary may not assign the
Deutsche Telekom/Powertel merger agreement or any of their rights, interests or
obligations under the Deutsche Telekom/Powertel merger agreement, in whole or in
part, to any other person, without the prior written consent of the non-
assigning parties; except that (1) Deutsche Telekom may assign the Deutsche
Telekom/Powertel merger agreement to an entity which owns more than 80% of the
Deutsche Telekom ordinary shares and which succeeds to all of the rights and
obligations of Deutsche Telekom under the Escrow Agency Agreement executed
pursuant to the Deutsche Telekom/Powertel merger agreement and (2) merger
subsidiary may assign the Deutsche Telekom/Powertel merger agreement to an
entity which is a direct, wholly-owned subsidiary of the entity to which
Deutsche Telekom has assigned the agreement under (1) above.

     Important Definition

     "material adverse effect".  As used in the Deutsche Telekom/Powertel merger
agreement, a "material adverse effect" on any company means any change in or
effect on the business of the company and its subsidiaries that is or is
reasonably likely to be materially adverse to the business, operations or
financial condition of the company.

     However, "material adverse effect" does not include the effects of changes
or developments:

     - in the wireless telecommunications industry, including regulatory and
       political conditions, and not uniquely relating to Deutsche Telekom or
       Powertel;

     - in the U.S. or European economy;

                                       169
<PAGE>   188

     - in the U.S. or European securities markets; or

     - resulting from the announcement or the existence of the Deutsche
       Telekom/Powertel merger agreement and the transactions contemplated by
       the Deutsche Telekom/Powertel merger agreement.

     Amendment and Restatement

     The Deutsche Telekom/Powertel merger agreement was originally entered into
between Deutsche Telekom and Powertel on August 26, 2000. On September 28, 2000
the Deutsche Telekom/Powertel merger agreement was amended and restated for the
purpose of making merger subsidiary a party to the agreement and other technical
changes.

DEUTSCHE TELEKOM'S AGREEMENTS WITH STOCKHOLDERS OF POWERTEL

     In connection with the execution of the Deutsche Telekom/Powertel merger
agreement, stockholders of Powertel who, in the aggregate, had sufficient voting
power as of the Powertel record date to approve the Deutsche Telekom/Powertel
merger entered into separate stockholder agreements with Deutsche Telekom and
agreed to vote all of their shares in favor of the Deutsche Telekom/Powertel
merger. We summarize the material terms of these agreements below, but this
description does not purport to describe all of their terms and is qualified in
its entirety by reference to the text of the agreements, copies of which have
been filed as exhibits to Deutsche Telekom's and VoiceStream's respective
registration statements and are incorporated herein by reference.

     The following Powertel stockholders and some of their affiliates have
entered into stockholder agreements with Deutsche Telekom in connection with the
Deutsche Telekom/Powertel merger:

    ITC Holding Company, Inc.
    SCANA Communications Holdings, Inc.
    Sonera Corporation
    Donald W. Burton and certain limited partnerships controlled by him
    American Water Works Company

     Agreement to Vote

     Each stockholder agreement obligates the stockholder that is a party to the
agreement to vote all its Powertel shares in favor of the Deutsche
Telekom/Powertel merger and the Deutsche Telekom/Powertel merger agreement and
to vote all of its Powertel shares against any alternative transaction, as
defined in the Deutsche Telekom/Powertel merger agreement and as discussed in
"The Deutsche Telekom/Powertel Merger Agreement -- Offers For Alternative
Transactions," or the liquidation or winding up of Powertel. Each stockholder's
obligation to vote in this manner applies whether or not the Powertel board of
directors continues to recommend the Deutsche Telekom/Powertel merger to the
Powertel stockholders.

     Transfer Restrictions and Waiver of Rights

     Each stockholder agreement restricts or limits the ability of the
stockholder that is a party to the agreement to sell, transfer, pledge, assign
or otherwise dispose of, including by short sale or the use of derivative or
futures contracts, any shares of, or rights to purchase, Powertel shares or,
until six months after completion of the Deutsche Telekom/Powertel merger,
Deutsche Telekom ADSs or Deutsche Telekom ordinary shares, in each case that are
subject to the stockholder agreement, except in limited circumstances, with
Deutsche Telekom's written consent or as expressly permitted by the stockholder
agreement or pursuant to the Deutsche Telekom/Powertel merger agreement. In that
regard, each stockholder agreement (other than the agreement with American Water
Works Company) provides that:

     - until the later of January 1, 2001 and the date of the Powertel special
       meeting, the stockholder may not sell, transfer, pledge, assign or
       otherwise dispose of, any Powertel shares or rights that are subject to
       the stockholder agreement;

     - from the later of January 1, 2001 and the date of the Powertel special
       meeting, until the earlier of the completion of the Deutsche
       Telekom/Powertel merger or the termination of the Deutsche
       Telekom/Powertel merger agreement, the stockholder may sell or transfer
       up to an aggregate of 17.5% of the total number of Powertel shares owned
       by such stockholder, which percentage increases to 21.25% on August 1,
       2001 and to 25% on September 1, 2001 if the Deutsche Telekom/Powertel
       merger is not completed by those dates;

     - from the completion of the Deutsche Telekom/Powertel merger through and
       including the three month anniversary of the completion of the Deutsche
       Telekom/Powertel merger, the stockholder may not sell or transfer any
       Deutsche Telekom ADSs, Deutsche Telekom ordinary shares or securities
       convertible into Deutsche Telekom ADSs or Deutsche Telekom ordinary
       shares;

                                       171
<PAGE>   190

     - from the day following the three month anniversary of the completion of
       the Deutsche Telekom/ Powertel merger, through and including the six
       month anniversary of the completion of the Deutsche Telekom/Powertel
       merger, the stockholder may sell or transfer up to an aggregate of 40% of
       the total number of Deutsche Telekom ADSs or Deutsche Telekom ordinary
       shares owned by the stockholder (as calculated pursuant to the
       stockholder agreement); and

     - after the six month anniversary of the completion of the Deutsche
       Telekom/Powertel merger, all sale and transfer restrictions end.

     Each stockholder (other than American Water Works Company) agreed to waive,
until the earlier of the completion of the Deutsche Telekom/Powertel merger or
termination of the Deutsche Telekom/ Powertel merger agreement, any preemptive
rights and, until the earlier of (1) the later of (A) January 1, 2001 and (B)
the date of Powertel special meeting and (2) the termination of the Deutsche
Telekom/ Powertel merger agreement, any registration rights they may have. Each
stockholder also agreed to terminate any of its existing registration rights
agreements with Powertel upon the completion of the Deutsche Telekom/VoiceStream
merger.

     In some circumstances, if Deutsche Telekom acquires any other company for
consideration in excess of $15 billion and significant stockholders of the
acquired company enter into agreements or could reasonably be expected to enter
into agreements with Deutsche Telekom that are more favorable to those
stockholders in terms of the obligations to vote in favor of the related
transaction or to refrain from selling or transferring shares, the transfer
restrictions in the stockholder agreements will be modified to reflect the more
favorable provisions or absence of restrictions, as the case may be.

     Termination

     Each stockholder agreement will terminate upon the earliest to occur of:

     - the completion of the Deutsche Telekom/Powertel merger;

     - the termination of the Deutsche Telekom/Powertel merger agreement; and

     - August 26, 2002.

     No Solicitation

     Each stockholder agrees not to solicit, initiate or participate in, and not
to authorize any representatives to solicit, initiate or participate in,
discussions or negotiations regarding transactions or business combinations
between Powertel and a company other than Deutsche Telekom, except as otherwise
permitted by the Deutsche Telekom/Powertel merger agreement. See "The Deutsche
Telekom/ Powertel Merger Agreement -- Offers for Alternative Transactions."

     The Stockholder Agreement with American Water Works Company

     The transfer restrictions described above applicable to each of the
stockholder agreements do not apply to American Water Works Company. The
American Water Works Company stockholder agreement only restricts transfers of
Powertel shares by the American Water Works Company as described below:

     - until the date of the Powertel special meeting, the American Water Works
       Company may not sell, transfer, pledge, assign or otherwise dispose of,
       any Powertel shares or rights that are subject to its stockholder
       agreement; and

     - until the date of the Powertel special meeting, the American Water Works
       Company may not effect, directly or indirectly, or through any
       arrangement with a third party pursuant to which such third party may
       effect, directly or indirectly, any short sales of Powertel shares that
       are subject to its stockholder agreement, as well as any short sales of
       Deutsche Telekom ADS, Deutsche Telekom ordinary shares or securities
       convertible into Deutsche Telekom ADSs or Deutsche Telekom ordinary
       shares that are subject to the agreement.

DEUTSCHE TELEKOM'S AGREEMENT WITH JOINT VENTURE PARTNERS OF POWERTEL

     Agreement with Eliska Wireless Investors I, L.P.

     In connection with the execution of the Deutsche Telekom/Powertel merger
agreement, Deutsche Telekom entered into an agreement with Eliska Wireless
Investors, a joint venture partner of Powertel. We summarize the material terms
of this agreement below, but this description does not purport to describe all
of its terms and is qualified in its entirety by reference to the text of the
agreement, a copy of which has been filed as exhibits to Deutsche Telekom's and
VoiceStream's respective registration statements and are incorporated herein by
reference.

     Under the agreement with Eliska Wireless Investors, Deutsche Telekom agreed
to assume on the date the Deutsche Telekom/Powertel merger is completed various
obligations of Powertel under an existing agreement relating to Eliska Wireless
Investors' rights, exercisable at various times, to exchange its ownership
interest in Eliska Wireless Ventures for shares or cash. Eliska Wireless
Investors agreed that its registration rights under an existing agreement will
be terminated on the date the Deutsche Telekom/ Powertel merger is completed.

     Agreement with Sonera Holding B.V.

     Deutsche Telekom has agreed to assume, on the date the Deutsche
Telekom/Powertel merger is completed, obligations under an existing agreement
between Powertel and Sonera Holding B.V. relating to the DiGiPH transaction,
including, without limitation, Sonera Holding's B.V. right to exchange its
ownership interest in Eliska Wireless Ventures for Deutsche Telekom shares.

THE VOICESTREAM/POWERTEL MERGER AGREEMENT

     This section of the proxy statement/prospectus is a summary of the
principal provisions of the VoiceStream/Powertel merger agreement. This summary
does not purport to be complete and is qualified in its entirety by reference to
the VoiceStream/Powertel merger agreement, a copy of which is attached as Annex
C to this proxy statement/prospectus and incorporated herein by reference.
VoiceStream and Powertel stockholders are urged to read the VoiceStream/Powertel
merger agreement in its entirety, as it is the legal document governing the
VoiceStream/Powertel merger. This section assumes that the VoiceStream/Powertel
merger will occur. You should remember, however, that the VoiceStream/Powertel
merger will not occur if the Deutsche Telekom/VoiceStream merger occurs.

     The VoiceStream/Powertel Merger

     A Delaware corporation formed by VoiceStream, will merge with and into
Powertel, and, as a result, Powertel will become a wholly-owned subsidiary of
VoiceStream.

     Effective Time and Timing of Closing

     The VoiceStream/Powertel merger will be completed and become effective when
Powertel files a certificate of merger with the Secretary of State of the State
of Delaware or at such later time as is specified in the certificate of merger
in accordance with Delaware law. We expect the VoiceStream/ Powertel merger to
become effective on the same day as the closing of the VoiceStream/Powertel
merger, which will take place on the fifth business day after the conditions to
the VoiceStream/Powertel merger have been satisfied or waived, or on such other
date as VoiceStream and Powertel may agree. In addition, on the closing date of
the VoiceStream/Powertel merger or as soon as possible after the closing date,
VoiceStream and Powertel will undertake a number of additional actions,
including making filings with regulatory and stock exchange authorities,
necessary to permit the issuance of the VoiceStream/Powertel merger
consideration under Delaware law and the rules of the Nasdaq Stock Market.

  Consideration to be Received in the VoiceStream/Powertel Merger

     In the VoiceStream/Powertel merger, holders of Powertel common shares will
receive for each of their Powertel common shares a number of VoiceStream common
shares determined as follows: (1) 0.75 of a VoiceStream common share if the
VoiceStream average closing price is $113.33 or below; (2) 0.65 of a VoiceStream
common share if the VoiceStream average closing price is $130.77 or above; and
(3) if the VoiceStream average closing price is greater than $113.33 and less
than $130.77, the quotient determined by dividing $85.00 by the VoiceStream
average closing price. We refer to the number of VoiceStream common shares a
Powertel stockholder will receive in the VoiceStream/Powertel merger in exchange
for their Powertel common shares as the "conversion number." The conversion
number is subject to adjustment as described below.

     Holders of Powertel preferred shares will receive for each Powertel
preferred share the right to receive a number of VoiceStream common shares
determined by multiplying the conversion number by the sum of (A) the number of
Powertel common shares into which such Powertel preferred share would be
converted as of the completion of the VoiceStream/Powertel merger plus (B) with
respect to Powertel Series E preferred shares and Series F preferred shares, the
number of Powertel common shares that represent accrued or declared but unpaid
dividends on those Powertel preferred shares. The "VoiceStream average closing
price" means the volume weighted average closing price, based on the Nasdaq
composite volume published by The Wall Street Journal, of the VoiceStream common
shares as publicly reported on the Nasdaq Stock Market as of 4:00 p.m. eastern
time on 10 trading days randomly selected from the 20 trading-day period ending
five trading days prior to the completion of the VoiceStream/Powertel merger.

     Adjustment of Conversion Number.  The conversion number was determined
assuming that, when the VoiceStream/Powertel merger is completed, the aggregate
number of Powertel common shares outstanding on a fully diluted basis and
adjusted for specific commitments to issue Powertel common shares (excluding
Powertel common shares issuable as dividends after August 26, 2000 on the Series
E preferred shares and Series F preferred shares), an aggregate number of
Powertel shares we call the "adjusted fully diluted shares amount", will not
exceed the "maximum share amount". The maximum share amount is 55,742,000 and
may be reduced as set forth in the VoiceStream/Powertel merger agreement. The
conversion number is subject to adjustment in the event that the adjusted fully
diluted shares amount as of the date the VoiceStream/Powertel merger is
completed exceeds the maximum share amount. In the event of an adjustment, the
effect will be to cap the number of VoiceStream common shares that will be
issued in the VoiceStream/Powertel merger and to reduce the number of
VoiceStream common shares to be received by each Powertel stockholder,
optionholder and warrantholder in the VoiceStream/Powertel merger in exchange
for each of their Powertel common shares or Powertel preferred shares, as the
case may be.

     We illustrate below how the adjustment mechanism will be used.

     - Step 1. Derive the adjusted fully diluted shares amount: The adjusted
       fully diluted shares amount is the sum of the number of outstanding
       Powertel common shares, less the number of shares issuable as dividends
       after August 26, 2000 on the Series E preferred shares and Series F
       preferred shares, plus

        - the number of Powertel common shares issuable upon conversion of the
          Powertel preferred shares;

        - the number of Powertel common shares issuable pursuant to the exercise
          of Powertel stock options and Powertel warrants;

        - the number of Powertel common shares issuable pursuant to Powertel
          restricted stock awards;

        - the number of Powertel common shares issuable pursuant to the exercise
          of the put rights held by Sonera Holding B.V. and Eliska Wireless
          Investors, unless such rights have been terminated;

                                       174
<PAGE>   193

        - the number of Powertel common shares issuable pursuant to the stock
          purchase agreement between Powertel and Sonera Holding B.V., unless
          this stock purchase agreement has been terminated;

        - the number of Powertel common shares issuable pursuant to the exercise
          of any stock appreciation rights, phantom stock rights or other
          contractual rights the value of which is determined in whole or in
          part by the value of any Powertel shares; and

        - the number of Powertel common shares issuable pursuant to any other
          securities outstanding, which are convertible into, or exercisable or
          exchangeable for, Powertel common shares.

     - Step 2. Derive the adjustment factor: The adjustment factor is a fraction
       (a) the numerator of which is 55,742,000, as it may be adjusted in
       accordance with the VoiceStream/Powertel merger agreement, and (b) the
       denominator of which is the adjusted fully diluted shares amount.

     - Step 3. Derive the adjusted Conversion Number: The conversion number will
       be reduced by multiplying the conversion number by the adjustment factor.

     - Step 4. Derive the adjusted stock consideration: Each outstanding
       Powertel common share, each Powertel common share issuable upon the
       exercise of outstanding Powertel warrants and Powertel Stock options and
       each Powertel preferred share will then be converted in the VoiceStream/
       Powertel merger into the right to receive a number of VoiceStream common
       shares equal to the adjusted conversion number calculated pursuant to
       Step 3.

Example. If the adjusted fully diluted shares amount exceeds 55,742,000, as it
may be adjusted in accordance with the VoiceStream/Powertel merger agreement, we
would calculate the number of VoiceStream common shares into which each Powertel
share will be converted as illustrated above. Assuming that the adjusted fully
diluted shares amount is 55,795,000, then the adjustment factor would be 0.9991.
If you own 100 Powertel common shares and the VoiceStream average closing price
is $110.00 under these circumstances, you would receive the amount of
VoiceStream common shares equal to 0.75 multiplied by 0.9991, multiplied by the
number of shares you hold, or 100, for a total of 74 VoiceStream common shares,
plus cash for 0.929 of a VoiceStream common share.

     Powertel stockholders will not receive fractional VoiceStream common shares
and instead will receive an amount of cash calculated in the manner described
below in "-- Exchange of Certificates Representing Powertel Shares."

     Other Potential Adjustments.  The conversion number will be adjusted in the
event that one of the following occurs or the record date for one of the
following is set before the completion of the VoiceStream/Powertel merger:

     - any reclassification, stock-split or stock dividend with respect to the
       VoiceStream common shares;

     - any change, exchange or conversion of VoiceStream common shares into
       other securities or property; or

     - any dividend or distribution with respect to VoiceStream common shares.

     Treatment of Powertel Warrants

     VoiceStream will assume all obligations of Powertel with respect to any
warrants to purchase Powertel common shares granted pursuant to the warrant
agreement dated February 7, 1996 between Powertel and Bankers Trust Company, as
warrant agent, outstanding at the time the VoiceStream/Powertel merger is
completed.

     Exchange of Certificates Representing Powertel Shares

     ChaseMellon Shareholder Services LLC shall act as exchange agent in the
VoiceStream/Powertel merger. Shortly after the VoiceStream/Powertel merger is
completed, ChaseMellon shall mail to each

                                       175
<PAGE>   194

registered holder of Powertel common shares and Powertel preferred shares a
letter of transmittal which the holder must properly complete and deliver to the
exchange agent with the holder's stock certificates.

     After a record holder of Powertel shares delivers certificates for those
shares and a properly completed letter of transmittal to the exchange agent, the
exchange agent will deliver to the holder:

     - the number of whole VoiceStream common shares included in the merger
       consideration in respect of such Powertel shares; and

     - a check in the amount (after giving effect to any required tax
       withholdings) of (1) any cash in lieu of any fractional interest in
       VoiceStream common shares on the terms described below, plus (2) any cash
       dividends or other distributions that the holder has the right to
       receive, including dividends or other distributions payable with respect
       to the holders of VoiceStream common shares with a record date after the
       completion of the VoiceStream/Powertel merger and a payment date on or
       before the date the holder properly delivers Powertel stock certificates
       to the exchange agent.

     The exchange agent will not deliver fractional VoiceStream common shares in
connection with the VoiceStream/Powertel merger. Instead, each holder of
Powertel shares exchanged in the VoiceStream/Powertel merger who would otherwise
have received a fraction of a VoiceStream common share will be entitled to
receive an amount in cash determined by multiplying the per share closing price
on the Nasdaq Stock Market of VoiceStream common shares on the date on which the
VoiceStream/ Powertel merger is completed by the fractional share to which the
holder would otherwise be entitled.

     Powertel shares that are surrendered to the exchange agent will be
canceled. No interest will be paid or accrued on any amount payable to holders
of Powertel shares. In addition, no holder of Powertel shares will receive any
dividends or other distributions with respect to VoiceStream common shares to
which the holder is entitled under the VoiceStream/Powertel merger agreement
until that holder's Powertel certificate is surrendered to the exchange agent
with a properly completed letter of transmittal.

     If any VoiceStream common shares are to be delivered to a person other than
the registered holder of the Powertel shares represented by the certificates
surrendered to the exchange agent:

     - those Powertel certificates must be properly endorsed or otherwise be in
       proper form for transfer; and

     - the person requesting the delivery must pay to the exchange agent any
       transfer or other taxes required as a result of delivery to a person
       other than the registered holder, or establish to the satisfaction of the
       exchange agent that such tax has been paid or is not payable.

     VoiceStream or the exchange agent shall be entitled to deduct and withhold
from the consideration otherwise payable pursuant to any holder of Powertel
shares any amounts they are required to deduct and withhold with respect to the
making of such payment under the U.S. tax code or under any provision of state,
local or foreign tax law.

     Treatment of Powertel Options and Restricted Stock

     Powertel Options.  If the VoiceStream/Powertel merger is completed, each
outstanding Powertel stock option will be converted into an option to purchase
the number of VoiceStream common shares determined by multiplying the number of
Powertel common shares subject to the option immediately prior to completion of
the VoiceStream/Powertel merger by the applicable conversion number. The
exercise price per share of VoiceStream common share for each of these options
will be the exercise price per Powertel common share applicable to that option
immediately prior to the completion of the Voicestream/Powertel merger divided
by the conversion number increased to the nearest whole cent. The replacement
options will generally have the same terms and conditions as were applicable
under the Powertel option plans.

                                       176
<PAGE>   195

     Powertel Restricted Stock.  At the time the VoiceStream/Powertel merger is
completed, the Powertel restricted stock plan will terminate and any unvested
Powertel restricted stock awards will become fully vested, except as otherwise
provided in the individual restricted stock award agreements.

     Dissenting Shares

     If appraisal rights for any Powertel shares are perfected by any
stockholder, then those shares will be treated as described under "The
VoiceStream/Powertel Merger -- Appraisal Rights."

     Covenants of VoiceStream.  VoiceStream has agreed that until the
VoiceStream/Powertel merger is completed, VoiceStream and its subsidiaries will
not do any of the following without Powertel's prior written consent:

     - fail to make in a timely manner any filings with the SEC required under

       its method of accounting or its fiscal year; or

     - enter into or acquire any new line of business that is material to
       VoiceStream and is not strategically related to the current business or
       operations of VoiceStream.

     Offers for Alternative Transactions

     Powertel has agreed not to, has agreed not to permit any of its
subsidiaries to, has agreed not to authorize or permit any of its or their
respective officers, directors or employees to, and has agreed to use its best
efforts to cause its advisors and representatives not to:

     - solicit, initiate or encourage, or knowingly take any other action
       designed to facilitate, any alternative transaction, which we define
       below, to the VoiceStream/Powertel merger; or

     - continue or participate in any discussions or negotiations regarding any
       alternative transaction to the VoiceStream/Powertel merger.

     However, if at any time before Powertel stockholders approve the
VoiceStream/Powertel merger, Powertel receives an unsolicited proposal for an
alternative transaction, then Powertel may, after giving VoiceStream three
business days' advance written notice:

     (1) furnish information with respect to Powertel pursuant to a
         confidentiality agreement substantially similar to the confidentiality
         agreement in place between VoiceStream and Powertel; and

     (2) engage in discussions and negotiations with the persons that made such
         proposal;

     - but only if:

        (A) the Powertel board of directors has determined in good faith, after
            receiving advice from outside counsel, that providing information to
            the third party or participating in negotiations or discussions
            could be reasonably expected to result in a superior proposal, which
            we define below, being made; and

        (B) Powertel is not otherwise in breach of its obligations described
            above not to solicit or engage in discussions regarding an
            alternative transaction.

                                       181
<PAGE>   200

     Important Definitions:

     "alternative transaction" means, a proposal or intended proposal regarding
any of the following:

     - a transaction or series of transactions in which any third party would
       acquire, directly or indirectly, beneficial ownership of outstanding
       shares representing more than 20% of the voting power of the outstanding
       Powertel shares or pursuant to a tender offer or exchange offer;

     - any acquisition of or business combination with Powertel or any of its
       subsidiaries, as applicable, by a merger or other business combination;
       or

     - any transaction in which any third party acquires or would acquire,
       directly or indirectly, control of assets of Powertel or any of its
       subsidiaries for consideration equal to 20% or more of the fair market
       value of all of the outstanding Powertel shares on August 26, 2000.

An alternative transaction does not include the Deutsche Telekom/Powertel merger
or the Deutsche Telekom/Powertel merger agreement.

     "superior proposal" means any proposal made by a third party to enter into
an alternative transaction which the Powertel board of directors determines in
its good faith judgment based on, among other things, the advice of a financial
advisor of nationally recognized reputation, to be more favorable to Powertel's
stockholders than the VoiceStream/Powertel merger taking into account all
relevant factors (including whether, in the good faith judgment of the Powertel
board of directors, the third party is reasonably able to finance the proposed
transaction).

     Powertel also has agreed to notify VoiceStream promptly of any request for
information or of any proposal in connection with an alternative transaction,
including the material terms of the request or proposal and the identity of the
person making it, and Powertel has agreed to keep VoiceStream fully informed of
the status of any alternative transaction. In addition, Powertel agreed to cease
all activities, discussions or negotiations with respect to an alternative
transaction that existed at the time the VoiceStream/Powertel merger agreement
was signed.

     Powertel's Board of Directors' Recommendation

     The VoiceStream/Powertel merger agreement requires the Powertel board of
directors:

     (1) to recommend that the Powertel stockholders approve the
         VoiceStream/Powertel merger agreement;

     (2) not to withdraw, modify or qualify, or to propose publicly to withdraw,
         modify or qualify, its recommendation in a manner adverse to
         VoiceStream;

     (3) not to approve or recommend, or to propose publicly to approve or
         recommend any alternative transaction; and

     (4) not to cause Powertel to agree to engage in any alternative
         transactions.

     However, if the Powertel board of directors receives a superior proposal
before Powertel stockholders approve the VoiceStream/Powertel merger agreement,
the Powertel board of directors may inform the Powertel stockholders that it no
longer recommends approval of the VoiceStream/Powertel merger agreement, if:

     - Powertel sends VoiceStream written notice that Powertel has received a
       superior proposal, which states the terms of the superior proposal and
       the identity of the proposer, and that Powertel intends to change its
       recommendation regarding the VoiceStream/Powertel merger; and

     - five business days have passed since VoiceStream received the notice. In
       addition, Powertel must give VoiceStream reasonable opportunity to make
       adjustments in the terms of the VoiceStream/ Powertel merger agreement
       that would enable the Powertel board of directors to maintain its

its subsidiaries.

     At any time before the VoiceStream/Powertel merger is completed,
VoiceStream, Powertel and merger subsidiary may (1) extend the time for the
performance of any of the obligations or other acts required by the
VoiceStream/Powertel merger agreement, (2) waive any inaccuracies in the
representations and warranties contained in the VoiceStream/Powertel merger
agreement or in any document required to be delivered pursuant to the
VoiceStream/Powertel merger agreement and

                                       189
<PAGE>   208

(3) waive compliance with any of the agreements or conditions contained in the
VoiceStream/Powertel merger agreement.

     VoiceStream, Powertel and merger subsidiary may not assign the
VoiceStream/Powertel merger agreement or any of their rights, interests or
obligations under the VoiceStream/Powertel merger agreement without the prior
written consent of the non-assigning parties.

     Important Definitions

     "material adverse effect."  As used in the VoiceStream/Powertel merger
agreement, a "material adverse effect" on any company means any change, effect,
fact or condition that is materially adverse to the business, properties,
assets, results of operations or financial condition of the company and its
subsidiaries. "Material adverse effect" shall include any event, fact or
condition which would reasonably be expected to materially delay, interfere
with, impair or prevent the transactions contemplated by the
VoiceStream/Powertel merger agreement in a manner that would have a material
adverse effect on such transactions.

     However, "material adverse effect" does not include any adverse change,
effect or development that is primarily caused by:

     - conditions affecting the U.S. economy generally or the economy of any
       nation or region in which VoiceStream or Powertel and their subsidiaries
       conduct business that is material to their businesses;

     - conditions generally affecting the industries in which VoiceStream or
       Powertel conduct their businesses;

     - the announcement or existence of the VoiceStream/Powertel merger
       agreement and the transactions contemplated by the VoiceStream/Powertel
       merger agreement.

     Amendment and Restatement

     The VoiceStream/Powertel merger agreement was originally entered into
between VoiceStream and Powertel on August 26, 2000. On September 28, 2000, the
VoiceStream/Powertel merger agreement was amended and restated for the purpose
of making merger subsidiary a party to the VoiceStream/Powertel merger agreement
and other technical changes.

VOICESTREAM'S AGREEMENTS WITH STOCKHOLDERS OF POWERTEL

     In connection with the execution of the VoiceStream/Powertel merger
agreement, VoiceStream entered into separate agreements with Powertel
stockholders who, in the aggregate, had sufficient voting power as of the
Powertel record date to approve the VoiceStream/Powertel merger. We summarize
the material terms of these agreements below, but this description does not
purport to describe all of their terms and is qualified in its entirety by
reference to the text of the stockholder agreements, copies of which have been
filed as exhibits to VoiceStream's and Deutsche Telekom's respective
registration statement and are incorporated herein by reference.

     The following Powertel stockholders and some of their affiliates have
entered into stockholder agreements with VoiceStream in connection with the
VoiceStream/Powertel merger:

     ITC Holding Company, Inc.
     SCANA Communications Holdings, Inc.
     Sonera Corporation
     Donald W. Burton and certain limited partnerships controlled by him
     American Water Works Company

                                       190
<PAGE>   209

     Agreement to Vote

     Each stockholder agreement obligates the stockholder that is a party to the
agreement to vote all its Powertel shares in favor of the VoiceStream/Powertel
merger and the VoiceStream/Powertel merger agreement and to vote all of its
Powertel shares against any alternative transaction, as defined in the
VoiceStream/Powertel merger agreement and as discussed in the
"-- VoiceStream/Powertel Merger Agreement -- Offers For Alternative
Transactions," or the liquidation or winding up of Powertel. Each stockholder's
obligation to vote in this manner applies whether or not the Powertel board of
directors continues to recommend the VoiceStream/Powertel merger to the Powertel
stockholders.

     Transfer Restrictions

     Each stockholder agreement restricts or limits the ability of the
stockholder that is a party to the agreement to sell, transfer, pledge, assign
or otherwise dispose of, any of its Powertel shares, or rights to purchase
Powertel shares or, until six months after completion of the
VoiceStream/Powertel merger, VoiceStream common shares, in each case that are
subject to the stockholder agreement. The stockholders that are parties to the
stockholder agreements can sell, transfer, pledge, assign or otherwise dispose
of their Powertel shares or VoiceStream shares, as the case may be, in limited
circumstances, with VoiceStream's written consent, as expressly permitted by the
stockholder agreement, pursuant to the VoiceStream/Powertel merger agreement or
pursuant to the Deutsche Telekom/Powertel merger agreement. In that regard, each
stockholder agreement, other than the agreement with American Water Works
Company, provides that:

     - until the later of January 1, 2001 and the date of the Powertel special
       meeting, the stockholder may not sell, transfer, pledge, assign or
       otherwise dispose of, any Powertel shares or rights that are subject to
       the stockholder agreement;

     - from the later of January 1, 2001 and the date of the Powertel special
       meeting, until the earlier of the completion of the VoiceStream/Powertel
       merger or the termination of the VoiceStream/Powertel merger agreement,
       the stockholder may sell or transfer up to an aggregate of 25% of the
       number of Powertel shares owned by such stockholder, which percentage
       increases commensurately to that percentage sold, subject to certain
       exempt transfers, by any VoiceStream stockholder who executed a
       VoiceStream stockholder agreement pursuant to the VoiceStream/Powertel
       merger agreement;

     - from the completion of the VoiceStream/Powertel merger through and
       including the six month anniversary of the completion of the
       VoiceStream/Powertel merger, the stockholder may not sell, transfer,
       pledge, assign or otherwise dispose of, any VoiceStream common shares
       that are subject to the stockholder agreement except in accordance with
       Rule 144 and Rule 145 of the Securities Act, except that if a VoiceStream
       stockholder who executed a VoiceStream stockholder agreement pursuant to
       the VoiceStream/Powertel merger agreement proposes to transfer more than
       the number of shares permitted to be transferred under Rule 144, subject
       to certain exempt transfers, then the Powertel stockholder may transfer
       shares under its registration rights commensurate with that percentage
       sold by the VoiceStream stockholder; and

     - after the six-month anniversary of the completion of the
       VoiceStream/Powertel merger, all contractual sale and transfer
       restrictions end.

     For a description of the stockholder agreements executed by VoiceStream
stockholders pursuant to the VoiceStream/Powertel merger agreement, see
"Powertel's Agreements with Stockholders of VoiceStream."

<PAGE>   210

     Termination

     Each stockholder agreement will terminate upon the earliest to occur of:

     - the completion of the VoiceStream/Powertel merger;

     - the termination of the VoiceStream/Powertel merger agreement; and

     - August 26, 2002.

     No Solicitation

     Each stockholder agrees not to initiate or participate in, and not to
authorize any representatives to solicit, initiate or participate in,
discussions or negotiations regarding transactions or business combinations
between Powertel and a company other than VoiceStream, except as otherwise
permitted by the VoiceStream/Powertel merger agreement. See "-- The
VoiceStream/Powertel Merger Agreement -- Offers for Alternative Transactions".

     Registration Rights

     Each stockholder agreement provides for minor modifications to existing
registration rights held by the parties to the stockholder agreements.

     The Stockholder Agreement with American Water Works Company

     The transfer restrictions described above applicable to each of the
stockholder agreements do not apply to American Water Works Company. The
American Water Works Company stockholder agreement only restricts transfers of
Powertel shares by the American Water Works Company as described below:

     - until the date of the Powertel special meeting, the American Water Works
       Company may not sell, transfer, pledge, assign or otherwise dispose of,
       any Powertel shares or rights that are subject to its stockholder
       agreement; and

     - until the date of the Powertel special meeting, the American Water Works
       Company may not effect, directly or indirectly, or through any
       arrangement with a third party pursuant to which such third party may
       effect, directly or indirectly, any short sales of Powertel shares that
       are subject to its stockholder agreement.

     Amendment of Existing VoiceStream Voting Agreements

     Each stockholder agreement provides that VoiceStream will execute and
deliver and use its reasonable best efforts to cause the parties to the existing
VoiceStream Voting Agreement, dated February 25, 2000, and the VoiceStream First
Amended and Restated Voting Agreement, dated July 23, 2000, voting agreements to
provide for the nomination of one Powertel nominee to the VoiceStream board of
directors and to vote all shares held by those VoiceStream stockholders for that
Powertel nominee at the first two annual meetings of VoiceStream following the
completion of the VoiceStream/Powertel merger. In the event the amendment to the
existing VoiceStream voting agreements is not executed, VoiceStream agrees to
enter into a new voting agreement with the Powertel stockholders who executed
stockholder agreements in connection with the VoiceStream/Powertel merger
agreement and VoiceStream stockholders who executed stockholder agreements in
connection with the VoiceStream/Powertel merger agreement which will contain
substantially the same provisions set forth in the previous sentence.

POWERTEL'S AGREEMENTS WITH STOCKHOLDERS OF VOICESTREAM

     In connection with the execution of the VoiceStream/Powertel merger
agreement, Powertel entered into separate agreements with VoiceStream
stockholders who, in the aggregate, had sufficient voting power as of the
VoiceStream record date to approve the VoiceStream/Powertel merger. Deutsche
Telekom agreed in the Deutsche Telekom/Powertel merger agreement to vote in
favor of the VoiceStream/Powertel

                                       192

merger. We summarize the material terms of these agreements below, but this
description does not purport to describe all of their terms and is qualified in
its entirety by reference to the text of the stockholder agreements, copies of
which have been filed as exhibits to VoiceStream's and Deutsche Telekom's
registration statements and are incorporated herein by reference.

     The following VoiceStream stockholders and some of their affiliates have
entered into stockholder agreements with Powertel in connection with the
VoiceStream/Powertel merger:

     Telephone & Data Systems, Inc.
     Hutchison Whampoa Ltd.
     Sonera Corporation
     John W. Stanton and Theresa E. Gillespie
     The Goldman Sachs Group, Inc.

     Agreement to Vote

     Each stockholder agreement obligates the stockholder that is a party to the
agreement to vote all of its VoiceStream shares in favor of the
VoiceStream/Powertel merger and the VoiceStream/Powertel merger agreement. The
Deutsche Telekom/Powertel merger agreement obligates Deutsche Telekom to vote
all of its VoiceStream shares in favor of the VoiceStream/Powertel merger and
the VoiceStream/ Powertel merger agreement. Each stockholder's obligation to
vote in this manner is irrevocable and unconditional.

     Transfer Restrictions

     Each of the stockholder agreements and, with respect to Deutsche Telekom,
the Deutsche Telekom/ Powertel merger agreement, restricts or limits the ability
of the stockholder that is a party to the agreement to sell, transfer, pledge,
assign or otherwise dispose of any VoiceStream shares owned by such stockholder
until the later of January 1, 2001 and the date of the VoiceStream special
meeting, except to affiliates and by operation of law, in each case where the
transferees agree to be bound by the terms of the stockholder agreement.

     Each VoiceStream stockholder who is a party to a stockholder agreement, not
including Deutsche Telekom, has agreed as follows:

     - from the later of January 1, 2001 and the date of the VoiceStream special
       meeting, until the earlier of the completion of the VoiceStream/Powertel
       merger or the termination of the VoiceStream/ Powertel merger agreement,
       if a stockholder proposes to sell, transfer, or exercise registration
       rights with respect to more than 25% of the stockholders' VoiceStream
       shares, then the stockholder must notify each of the Powertel
       stockholders who entered into stockholder agreements with VoiceStream of
       the proposed sale, transfer or exercise of rights and not to restrict
       these Powertel stockholders from exercising registration rights they
       maintain; and

     - for six months beginning on the closing of the VoiceStream/Powertel
       merger, if the stockholder proposes to sell, transfer, or exercise
       registration rights with respect to more VoiceStream shares than the
       stockholder is permitted to sell or transfer under the volume
       restrictions of Rule 144 of the Securities Act, the stockholder must
       notify each of the Powertel stockholders who entered into stockholder
       agreements with VoiceStream of the proposed sale, transfer or exercise of
       rights and either allow the Powertel stockholder to participate in the
       registration or agree not to prevent or delay the filing of a
       registration statement on behalf of any of these Powertel stockholders.

     Agreement to Elect a Powertel Nominee to the VoiceStream Board of Directors

     Each VoiceStream stockholder that is a party to a stockholder agreement has
agreed that it will vote all its VoiceStream common shares, and Deutsche Telekom
has agreed in the Deutsche Telekom/Powertel merger agreement to vote all of its
VoiceStream voting preferred shares at the two annual meetings of VoiceStream
following the closing of the VoiceStream/Powertel merger in favor of the
election to
                                       193
<PAGE>   212

VoiceStream's board of directors of one nominee (and successors of such nominee)
chosen by Powertel and acceptable to VoiceStream. After the completion of the
VoiceStream/Powertel merger, in the event a nominee or successor nominee chosen
by Powertel before the VoiceStream/Powertel merger is completed is unable or
unwilling to serve, two current Powertel stockholders may, by mutual agreement,
name an alternate successor. Deutsche Telekom's obligation is not enforceable if
it would reduce its rights to appoint directors representing 10% of
VoiceStream's board of directors. To effect these voting arrangements, these
VoiceStream stockholders have agreed to amend existing VoiceStream voting
agreements to which they are parties. See "VoiceStream's Agreements with
Stockholders of Powertel -- Amendment of Existing VoiceStream Voting
Agreements."

     Termination

     Each of the stockholder agreements, and the applicable provisions of the
Deutsche Telekom/Powertel merger agreement, will terminate upon the earliest to
occur of:

     - the completion of the VoiceStream/Powertel merger;

     - August 26, 2002; and

     - the termination of the VoiceStream/Powertel merger agreement.

     The Stockholder Agreement with Telephone & Data Systems, Inc.

     In addition to the general provisions described above applying to each of
the stockholder agreements, Telephone & Data Systems, Inc. and Powertel entered
into a letter agreement. This agreement provides that, in the event that the
board of directors of Telephone & Data Systems determines that Telephone & Data
Systems is subject to the regulations of the Investment Company Act of 1940 and
Telephone & Data Systems is unsuccessful in obtaining an exemption from such
regulations or is not eligible for an exemption, the restrictions on Telephone &
Data Systems' right to transfer VoiceStream common shares will be modified to
allow it to sell the minimum number of VoiceStream common shares that would
allow Telephone & Data Systems to avoid being characterized as an "investment
company" under the Investment Company Act of 1940.

                                 EXCHANGE RATES

     Effective January 1, 1999, Germany and ten other member states of the
European Union adopted the euro as their common currency. With the first quarter
of 1999, Deutsche Telekom began publishing its consolidated financial statements
in euros. Prior to January 1, 1999, Deutsche Telekom prepared its financial
statements in Deutsche Marks in accordance with German GAAP. Amounts stated in
euros appearing in this document for periods prior to January 1, 1999 have been
translated from Deutsche Marks at the official fixed conversion rate of 1.00 EUR
= DM 1.95583.

     Unless otherwise stated, dollar amounts have been translated from euros at
the noon buying rate in New York City for cable transfers in foreign currencies
as certified for customs purposes by the Federal Reserve Bank of New York on
____________, 2000. At that date, the noon buying rate for the euro was EUR ____
per U.S.$1.00, which if expressed in Deutsche Marks would have been equivalent
to a rate of DM ____ per U.S.$1.00, translated from euros at the official fixed
conversion rate. This rate may differ from the actual rates used in the
preparation of Deutsche Telekom's consolidated financial statements included or
incorporated by reference herein. Accordingly, dollar amounts appearing in this
proxy statement/prospectus may differ from the actual dollar amounts originally
translated into euros in the preparation of Deutsche Telekom's financial
statements.

     The following table sets forth (1) for the year 1999 and for the period
from January 1, 2000 through ____________, 2000, the average, high, low and

connection with the Deutsche Telekom/VoiceStream and Deutsche Telekom/Powertel
mergers will have the same dividend rights as the other outstanding Deutsche
Telekom ADSs and all other Deutsche Telekom ordinary shares, including dividend
rights with respect to the full fiscal year 2001. For information relevant to
receipt of dividend payments by Deutsche Telekom ADS holders, see "Exchange
Rates," "Description of Deutsche Telekom Ordinary Shares -- Dividends and Other

(1) Dividend amounts have been translated into dollars at the noon buying rate
    for the relevant dividend payment date, which occurred during the second
    quarter of the following year.

     The dividend levels of past years may not be indicative of future
dividends.

     Shareholders determine the declaration, amount and timing of dividends in
respect of each fiscal year at their annual general meeting in the following
year, upon the joint recommendation of the management board and the supervisory
board. As long as the Federal Republic and KfW own a majority of Deutsche
Telekom's voting share capital, they will have the power to control most
decisions taken at shareholders' meetings, including the approval of proposed
dividend payments. We expect that, as a result of the Deutsche
Telekom/VoiceStream merger and the Deutsche Telekom/Powertel merger, the Federal
Republic and KfW will no longer own a majority of Deutsche Telekom's voting
share capital. Deutsche Telekom may declare and pay dividends only from
distributable balance sheet profit (Bilanzgewinn) of Deutsche Telekom AG, as
adjusted to reflect losses or gains carried over from prior years as well as
transfers to or from retained earnings. Certain reserves (Rucklagen) are
required by law to be made and deducted in calculating distributable balance
sheet profits available for distribution as dividends.

     The payment of future dividends depends on Deutsche Telekom's earnings, its
financial condition and other factors, including cash requirements, the future
prospects of Deutsche Telekom and tax, regulatory and other legal
considerations. Although Deutsche Telekom expects to pay annual dividends on its
shares, you should not assume that any dividend will actually be paid or make
any assumption about the amount that will be paid in any given year. To the
extent necessary to implement Deutsche Telekom's dividend policy, Deutsche
Telekom will consider drawing upon its retained earnings. Deutsche Telekom's
ability to pay dividends is determined by reference to the unconsolidated
financial statements of Deutsche Telekom AG, which are prepared in accordance
with German GAAP. In 1999, Deutsche Telekom AG recognized gains from an
intra-group sale of its shares in Sprint of approximately 8.2 billion euros,
which contributed significantly to total net income of approximately 9.7 billion
euros on an unconsolidated basis. In the consolidated financial statements, the
net effect of this intra-group transfer was zero. Deutsche Telekom's net income
on a consolidated basis was 1.3 billion euros. The portion of the unconsolidated
income of Deutsche Telekom AG for 1999 that has not been allocated to dividends
has been allocated to retained earnings and may be drawn upon in connection with
future dividend payments. Dividends paid will be subject to German withholding
tax. For further information on German withholding tax and related U.S. refund
procedures, see "U.S. Federal and German Tax Consequences".

  VoiceStream

     VoiceStream has never declared or paid dividends on its common shares and
does not anticipate paying dividends in the foreseeable future. In addition,
VoiceStream has entered into certain credit agreements and indentures which
contain restrictions on its ability to declare and pay dividends on its common
shares. For more information on such restrictions, please refer to VoiceStream's
10-K for the fiscal year ended December 31, 1999, which is incorporated by
reference into this proxy statement/prospectus.

<PAGE>   219

  Powertel

     Powertel has never declared or paid cash dividends on its common shares and
does not anticipate paying cash dividends in the foreseeable future. Powertel's
Series E Preferred Shares and Series F Preferred Shares accrue a cumulative 6.5%
annual dividend that is payable quarterly in common shares or cash. However,
Powertel pays these dividends in common shares because it is prohibited from
paying cash dividends due to restrictions contained in agreements governing its
and its subsidiaries' indebtedness. For more information on such restrictions,
please refer to Powertel's Form 10-K for the fiscal year ended December 31,
1999, which is incorporated by reference into this proxy statement/prospectus.

                DESCRIPTION OF DEUTSCHE TELEKOM ORDINARY SHARES

     Set forth below is a summary of certain information relating to Deutsche
Telekom's share capital and of certain provisions of Deutsche Telekom's Articles
of Association and German law. This summary is not complete and is qualified by
reference to Deutsche Telekom's Articles of Association and German law as in
effect at the date of this proxy statement/prospectus.

SHARE CAPITAL

     Deutsche Telekom's share capital amounts to 7,755,786,327.04 euros divided
into 3,029,604,034 ordinary shares issued in registered form. The individual
ordinary shares do not have a par value as such, but they do have a notional par
value that can be determined by dividing the share capital amount by the number
of ordinary shares.

     Holders of ordinary shares (but not holders of ADSs) are required to
provide to Deutsche Telekom their names, addresses and occupations (or, in the
case of business entities, their names, business addresses and registered seats)
as well as the number of ordinary shares held, so that they can be entered into
the share register maintained by Deutsche Telekom. It is also possible to have a
third party ("street name") registered in lieu of the shareholders. ADEUS
Aktienregister-Service-GmbH (a joint venture of Dresdner Bank AG, Allianz AG,
Munchener Ruckversicherungs-Gesellschaft AG in Munchen and CSC Ploenzke AG) is
the transfer agent and registrar of the registered ordinary shares in Germany.
Citibank, N.A. is the depositary bank for the Deutsche Telekom ADSs. See
"Description of Deutsche Telekom American Depositary Shares" on page      .

     Generally, the share capital of Deutsche Telekom may be increased (other
than by conditional capital or authorized capital) in consideration of
contributions in cash or in kind by a resolution passed at a general meeting of
the shareholders of Deutsche Telekom by a majority of the votes cast.

     An English translation of the Deutsche Telekom Articles of Association
(Satzung) has been filed as an exhibit to this registration statement.

  Authorized Capital

     Section 5(2) of the Articles of Association (Satzung) of Deutsche Telekom
authorizes the Deutsche Telekom management board, with the approval of the
Deutsche Telekom supervisory board, to increase Deutsche Telekom's share capital
by up to a nominal amount of 3,865,093,163.52 euros by issuing up to
1,509,802,017 new ordinary shares for noncash contributions through May 25,
2005. In addition, according to Section 5(3) of the Articles of Association, the
Deutsche Telekom management board, with approval of the Deutsche Telekom
supervisory board, is authorized to increase Deutsche Telekom's share capital by
up to a nominal amount of 12,800,000 euros by issuing up to 5,000,000 new
ordinary shares for cash or noncash contributions for offerings to management
and key employees under a stock option plan through May 25, 2005. In both cases,
shareholders do not have preemptive rights (Bezugsrechte), which means that
existing shareholders of Deutsche Telekom do not have a right to subscribe for
new Deutsche Telekom shares in the capital increase in proportion to their
existing holdings of Deutsche Telekom shares before shares from the capital
increase may be sold to other persons.

                                       201
<PAGE>   220

  Conditional Capital

     Section 5(5) of the Articles of Association provides for a conditional
capital of up to a nominal amount of 64 million euros or up to 25 million new
ordinary shares. This conditional share capital may only be used if and to the
extent that option rights granted pursuant to Deutsche Telekom's stock option
plan described below are exercised and new ordinary shares are delivered upon
such exercise. Option rights that have not been or may not be exercised prior
the expiration of the exercise period will expire. The ordinary shares issued
from the conditional share capital generally will be entitled to any dividends
paid in respect of the year in which they are issued. Shares that are issued
after the end of any fiscal year, but before the ordinary general shareholders
meeting at which the activities of the Deutsche Telekom management board for
that year are approved, will be entitled to any dividends paid in respect of
that year.

     At their annual meeting on May 25, 2000, the shareholders of Deutsche
Telekom authorized the Deutsche Telekom supervisory board to grant stock options
to the members of its management board and authorized the Deutsche Telekom
management board to grant stock options to all other eligible participants. The
Deutsche Telekom supervisory board is authorized to determine the detailed terms
for the issuance of ordinary shares from the conditional share capital and for
the grant of options as well as the other terms of the stock option plan if the
Deutsche Telekom management board is the beneficiary of the stock option plan.
In all other cases, the Deutsche Telekom management board is authorized to make
these determinations.

     The principal terms of the stock option plan are:

     - Eligible Participants.  The conditional share capital may only be used to
       grant stock options to members of the Deutsche Telekom management board,
       senior management at the levels below the Deutsche Telekom Management
       Board and certain managers of Deutsche Telekom's domestic or foreign
       group companies. Of the total number of options available under the stock
       option plan, 20% may be granted to members of the Deutsche Telekom
       management board and 15% may be granted to managers of Deutsche Telekom's
       domestic and foreign group companies.

     - Lock-up Period, Exercise Period.  Options may not be exercised before the
       expiration of two years after they have been granted. They may be
       exercised for a period of three years following the lock-up period
       (exercise period).

     - Strike Price.  Each option entitles the holder to purchase one ordinary
       share at the strike price. The strike price of the options will be equal
       to the average of the closing prices quoted in the XETRA system of the
       Frankfurt Stock Exchange on the 30 trading days prior to the day on which
       the options are granted.

     - Performance Requirements.  The options may be exercised on any stock
       exchange trading day in Frankfurt am Main during the exercise period if
       both of the following performance requirements have been met:

        - Absolute Performance.  The average ordinary share price during any 30
          day period following the two year lock-up period must exceed the
          strike price of the options by at least 20%.

        - Relative Performance.  In addition, exercise of the options is linked
          to the performance of the ordinary shares relative to the performance
          of the Dow Jones Euro Stoxx 50 index. The options may only be
          exercised if, during any 30 day period following expiration of the two
          year lock-up period, the performance of the ordinary shares, adjusted
          for dividends, preemptive rights and other special rights (total
          shareholder return), exceeds the performance of the Euro Stoxx 50
          index.

     Under the authorization, stock options may be granted in annual tranches.
Stock options are to be granted within the eight week period following the
ordinary general shareholders meeting in each year. The last tranche of options
may be granted in 2004. The terms and conditions of the stock options may
provide Deutsche Telekom with the right to make a cash payment instead of
issuing new ordinary shares upon exercise.

                                       202
<PAGE>   221

     The terms and conditions of the options may also provide that the Deutsche
Telekom management board (and with respect to members of the Deutsche Telekom
management board, the Deutsche Telekom supervisory board) shall be authorized to
determine that in lieu of one ordinary share against payment of the strike
price, a smaller number of ordinary shares may be issued upon exercise of an
option against payment of the minimum issue price. If that determination is
made, then each option will not entitle the holder to purchase one ordinary
share at the strike price set at the time of issuance of the option, but only a
certain number of options will entitle the holder to purchase one ordinary share
at the minimum issue price. The number of options necessary to purchase one
ordinary share shall be determined as follows:

     On June 26, 2000, two Deutsche Telekom shareholders filed a suit with the
District Court in Bonn (Landgericht Bonn) seeking to have declared void the
shareholders resolutions authorizing both the stock option plan and a related
conditional capital increase. Deutsche Telekom cannot at present predict how
long it will take to resolve this litigation or what its outcome will be.

REPURCHASE OF SHARES

     Under the German Stock Corporation Act (Aktiengesetz), Deutsche Telekom may
not purchase its own ordinary shares, subject to certain limited exceptions.

     The general shareholders meeting on May 25, 2000 approved a resolution that
authorizes Deutsche Telekom pursuant to Section 71(1) no. 8 of the German Stock
Corporation Act to purchase its own ordinary shares in an amount representing up
to 10% of its registered share capital of approximately 7.76 billion euros
through November 15, 2001. The purchase price for the ordinary shares (excluding
purchasing costs) must not exceed or fall below the market price by more than
5%, in the case of a purchase on the stock exchange, or 20%, in the case of an
offer to purchase made to all shareholders. The relevant market price for this
purpose would be the opening auction price in the XETRA system of the Frankfurt
Stock Exchange on the day of the purchase, in the case of a purchase on the
stock exchange, or the closing price in the XETRA system on the day prior to the
publication of the offer, in the case of a public offer to purchase made to all
shareholders.

     Pursuant to the resolution, the Deutsche Telekom management board is
authorized, with approval of the Deutsche Telekom supervisory board, to:

     (1) list the acquired ordinary shares on foreign stock exchanges on which
they are not listed;

     (2) offer the acquired ordinary shares to third parties in the context of
mergers with and acquisitions of other companies and acquisitions of interests
in other companies; and

     (3) cancel the acquired ordinary shares without further shareholder
approval. This cancellation option can be exercised in whole or in part.

     Shareholders do not have preemptive rights for the purposes listed in
clauses (1) and (2) above. The price for any sale on a stock exchange or use in
a merger or acquisition transaction would not be permitted to be more than 5%
below the opening auction price of Deutsche Telekom's ordinary shares in the
XETRA system of the Frankfurt Stock Exchange on the day of the sale on the stock
exchange or the definitive agreement with a third party, as applicable.

VOTING RIGHTS AND SHAREHOLDER MEETINGS

     Each ordinary share entitles its holder to one vote at Deutsche Telekom's
general meeting of shareholders. Shareholders may pass resolutions at a general
meeting by a majority of the votes cast, unless a higher vote is required by law
or by the Deutsche Telekom Articles of Association. Neither the German Stock
Corporation Act nor the Articles of Association provide for minimum quorum
requirements for shareholders meetings. The German Stock Corporation Act and the
Articles of Association require that significant resolutions be passed by at
least 75% of the share capital represented at a meeting.

     These significant resolutions include:

     - capital increases which provide for an exclusion of preemptive rights;

     - capital decreases;

     - the creation of authorized capital (genehmigtes Kapital) or conditional
       capital (bedingtes Kapital);

     - dissolution of Deutsche Telekom;

     - merger of Deutsche Telekom into or consolidation of Deutsche Telekom with
       another stock corporation;

     - split- or spin-off;

     - transfer of all Deutsche Telekom's assets;

     - conclusion of intercompany agreements (Unternehmensvertrage), including,
       in particular, direct control and profit and loss pooling agreements;

     - amendments to the corporate purpose of Deutsche Telekom; and

     - a change in Deutsche Telekom's corporate form.

     A general meeting of the shareholders of Deutsche Telekom may be called by
the Deutsche Telekom management board, the Deutsche Telekom supervisory board or
by shareholders holding in the aggregate at least 5% of Deutsche Telekom's
issued share capital. The annual general meeting must take place within the
first eight months of the fiscal year and is called by the Deutsche Telekom
management board upon the receipt of the Deutsche Telekom supervisory board's
report on the annual financial statements. Under the Articles of Association,
the right to participate in and to vote at a shareholders meeting will only be
given to those shareholders who have timely registered for the shareholders
meeting in writing or by fax with the Deutsche Telekom management board at the
seat of the company and who are included in the share register when their
registration is received and on the date of the shareholders meeting. There must
be at least two days between receipt of the registration and the date of the
shareholders meeting. Deutsche Telekom must publish notice of shareholders
meetings in the Federal Gazette (Bundesanzeiger) at least one month prior to the
date by which shareholders have to register for the shareholders meeting. The
day of publication and the last date by which shareholders have to register for
the shareholders meeting are not counted for this purpose. In addition, Deutsche
Telekom must publish a notice in a national authorized stock exchange journal.

     Those shareholders who have given timely notice to Deutsche Telekom in
writing or by fax and who are registered in the share register at the time of
this notice may participate in and vote in the general shareholders meeting.
This notice must be given so that there are at least two days between the day
when the notice is given and the day of the general shareholders meeting.

DIVIDENDS AND OTHER DISTRIBUTIONS

     Deutsche Telekom may pay dividends immediately following the resolution by
the general meeting of shareholders on the distribution of profits. Shareholders
participate in profit distributions in proportion to the number of ordinary
shares held.

                                       204
<PAGE>   223

     Under German law, Deutsche Telekom may declare and pay dividends only from
balance sheet profits as shown in the unconsolidated annual financial statements
of Deutsche Telekom AG. In determining the distributable balance sheet profits,
the Deutsche Telekom management board and the Deutsche Telekom supervisory board
may allocate to profit reserves (andere Gewinnrucklagen), either in whole or in
part, the annual surplus (Jahresuberschuss) that remains after allocation to
statutory reserves and losses carried forward. Under the Deutsche Telekom
Articles of Association, transferring more than one-half of the annual surplus
is not permissible if, following the transfer, the accumulated reserves out of
surplus would exceed one-half of Deutsche Telekom's share capital. The
shareholders, in determining the distribution of profits, may allocate
additional amounts to profit reserves and may carry forward profits in part or
in full.

     Dividends approved at a shareholders meeting are payable on the first stock
exchange trading day after that meeting (unless otherwise decided at the
shareholders meeting). Details regarding paying agents are published in the
Federal Gazette (Bundesanzeiger). Shareholders holding ordinary shares through
Clearstream Banking AG will receive dividends by credit to their respective
accounts.

RECORD DATES

     In accordance with the German Stock Corporation Act, the record date for
determining which holders of Deutsche Telekom ordinary shares are entitled to
the payment of dividends or other distributions (whether in cash, stock or
property) will be the date of the general meeting of shareholders at which such
dividends or other distributions are declared. The record date for determining
which holders of Deutsche Telekom ordinary shares are entitled to vote at a
general meeting will be the date of such general meeting, provided that holders
of Deutsche Telekom ordinary shares who are registered in the share register
(Aktienbuch) on the date of the meeting will be entitled to attend and vote at
the meeting only if such holders have given Deutsche Telekom notice of their
desire to attend early enough that there are at least two days between the day
the notice is given and the day of the several shareholders' meeting.

PREEMPTIVE RIGHTS

     Under the German Stock Corporation Act, every shareholder generally has
preemptive rights with respect to an issuance of new ordinary shares (including
securities convertible into ordinary shares, securities with warrants to
purchase ordinary shares, profit-sharing certificates and securities with a
profit participation). Preemptive rights regarding a specific capital increase
are freely transferable and may be traded on the German stock exchanges for a
limited number of days prior to the final date for the exercise of the rights.
Shareholders may eliminate preemptive rights through a resolution passed by a
qualified majority of at least three quarters of the share capital represented
at a meeting. See "-- Share Capital -- Authorized Capital" for a description of
the authorized capital where preemptive rights have been eliminated. In
addition, an elimination of preemptive rights requires a report by the Deutsche
Telekom management board, which must justify the elimination by establishing
that Deutsche Telekom's interest in the elimination outweighs the shareholders'
interest in exercising their preemptive rights. Preemptive rights related to the
issuance of new ordinary shares may be eliminated without justification if:

     - Deutsche Telekom increases share capital for cash contributions;

     - the amount of the increase does not exceed 10% of the issued share
       capital; and

     - the ordinary shares are sold at a price not substantially lower than the
       current quoted share price.

     Shareholders do not have any preemptive rights with respect to ordinary
shares issued using conditional capital. See "-- Share Capital -- Conditional
Capital" for a description of the existing conditional capital.

LIQUIDATION RIGHTS

     In accordance with the German Stock Corporation Act, upon a liquidation of
Deutsche Telekom, shareholders will receive, in proportion to the ordinary
shares held, any liquidation proceeds remaining after paying off all of Deutsche
Telekom's liabilities.
                                       205
<PAGE>   224

NOTIFICATION REQUIREMENTS

     Under the German Securities Trading Act (Wertpapierhandelsgesetz), any
person whose direct or indirect voting interest reaches, exceeds or, after
reaching, falls below 5%, 10%, 25%, 50% or 75% of the voting rights in Deutsche
Telekom must, within no more than seven calendar days, inform Deutsche Telekom
and the Federal Supervisory Authority for Securities Trading (Bundesaufsichtsamt
fur den Wertpapierhandel) in writing (1) that such person has reached, exceeded
or fallen below one of these thresholds and (2) the extent of such person's
voting rights. Failure to notify Deutsche Telekom or the Federal Supervisory
Authority will, for so long as such failure continues, disqualify the
shareholder from exercising the rights attached to his ordinary shares
(including voting rights and, if the shareholder is acting intentionally, the
right to receive dividends). In addition, a penalty may be imposed as provided
for by law.

GERMAN FOREIGN EXCHANGE CONTROLS

     At present, the Federal Republic of Germany does not restrict the movement
of capital between Germany and other countries, except investments in Iraq,
Myanmar and Serbia and with institutions of the Taliban party in Afghanistan and
the UNITA party in Angola. This is to comply with the applicable resolutions
adopted by the United Nations and the European Union.

     For statistical purposes, with certain exceptions, every corporation or
individual residing in Germany is obligated to report any payment received from
or made to a non-resident corporation or individual to the German Central Bank
(Deutsche Bundesbank) if the payment exceeds DM 5,000 or EUR 2,500 (or the
equivalent in a foreign currency). Additionally, corporations and individuals
residing in Germany must report to the German Central Bank any claims of a
resident corporation or individual against or liabilities payable to a
non-resident corporation or individual exceeding an aggregate of DM 3.0 million
or 1.5 million euros (or the equivalent in a foreign currency) at the end of any
calendar month.

     Neither German law nor the Articles of Association restricts the right of
non-resident or foreign owners of the ordinary shares to hold or vote the
ordinary shares.

INSPECTION OF SHARE REGISTER

     The share register (Aktienbuch) of Deutsche Telekom will be maintained, on
behalf and under the responsibility of the Deutsche Telekom Management Board, by
ADEUS Aktienregister-Service-GmbH, for registration of any holder of Deutsche
Telekom ordinary shares, upon such holder's request, as a shareholder of
Deutsche Telekom. The share register will be open for inspection by the
shareholders of Deutsche Telekom during normal business hours at the principal
office of Deutsche Telekom in Bonn, Germany.

           DESCRIPTION OF DEUTSCHE TELEKOM AMERICAN DEPOSITARY SHARES

     Citibank, N.A. as depositary bank for the Deutsche Telekom ADSs will issue
Deutsche Telekom ADSs to you in the form of a certificated American Depositary
Receipt (also known as "ADR") upon completion of the Deutsche
Telekom/VoiceStream merger and the Deutsche Telekom/Powertel merger, unless you
elect to receive Deutsche Telekom ordinary shares. Each Deutsche Telekom ADS
represents one Deutsche Telekom ordinary share or the right to receive one
Deutsche Telekom ordinary share on deposit with the custodian bank. A Deutsche
Telekom ADS will also represent any other property received by the depositary
bank or the custodian on behalf of the owner of the Deutsche Telekom ADS but not
distributed to the owners of Deutsche Telekom ADSs because of legal restrictions
or practical considerations.

     Citibank's depositary offices are located at 111 Wall Street, New York, New
York 10043. Deutsche Telekom ADSs represent ownership interests in securities
that are on deposit with the depositary bank. The depositary bank typically
appoints a custodian to safekeep the securities on deposit. In this case, the
custodian is Citibank AG, located at Neue Mainzer Strasse 75, Frankfurt am Main,
Germany.

     Deutsche Telekom has appointed Citibank as depositary bank pursuant to a
deposit agreement. The depositary bank will make available for inspection by
holders at its office and at the office of Citibank AG copies of documents,
reports and communications in respect of the Deutsche Telekom ADSs, including
the deposit agreement and Deutsche Telekom's Articles of Association. A copy of
the deposit agreement is also on file with the SEC under cover of a Registration
Statement on Form F-6. See "Where You Find More Information" on page ____ for
the location of the SEC Public Reference Rooms where you can get copies of the
deposit agreement. The depository bank will also mail copies of documents or
reports and communications to you if requested by Deutsche Telekom to do so and
if it is lawful and practicable to do so. Please refer to Registration Number
333-05724 when retrieving a copy of the deposit agreement.

     Deutsche Telekom is providing you with a summary description of the
Deutsche Telekom ADSs and your rights as an owner of Deutsche Telekom ADSs.
Please remember that summaries by their nature lack the precision of the
information summarized and that your rights and obligations as an owner of
Deutsche Telekom ADSs will be determined by the deposit agreement and not by
this summary. Deutsche Telekom urges you to review the deposit agreement in its
entirety as well as the form of ADR attached to the deposit agreement.

     If you become an owner of Deutsche Telekom ADSs, you will become a party to
the deposit agreement and therefore will be bound by its terms and by the terms
of the ADR that represents your Deutsche Telekom ADSs. The deposit agreement and
the ADR specify Deutsche Telekom's rights and obligations as well as your rights
and obligations as an owner of Deutsche Telekom ADSs and those of the depositary
bank. As a Deutsche Telekom ADS holder you appoint the depositary bank to act on
your behalf in certain circumstances. The deposit agreement and the ADRs are
governed by New York law. However, Deutsche Telekom's obligations to the holders
of ordinary shares will continue to be governed by the laws of Germany, which
may be different from the laws in the United States. Deutsche Telekom will treat
the depositary bank as the holder of the shares represented by your ADSs.

     As an owner of Deutsche Telekom ADSs, you may hold your Deutsche Telekom
ADSs either by means of an ADR registered in your name or through a brokerage or
safekeeping account. If you decide to hold your Deutsche Telekom ADSs through
your brokerage or safekeeping account, you must rely on the procedures of your
broker or bank to assert your rights as a Deutsche Telekom ADS owner. Please
consult with your broker or bank to determine what those procedures are. This
summary description assumes you have opted to own the Deutsche Telekom ADSs
directly by means of an ADR registered in your name, and as such, you are
referred to as the "holder." When this summary refers to "you," it is on the
assumption that the reader owns new Deutsche Telekom ADSs and will own Deutsche
Telekom ADSs at the relevant time.

                                       207
<PAGE>   226

DIVIDENDS AND DISTRIBUTIONS

     As a holder, you generally have the right to receive the distributions
Deutsche Telekom makes on the securities deposited with the custodian bank. Your
receipt of these distributions may be limited, however, by practical
considerations and legal limitations. Holders will receive the distributions
under the terms of the deposit agreement in proportion to the number of Deutsche
Telekom ADSs held as of a specified record date.

  Distributions of Cash

     Whenever Deutsche Telekom makes a cash distribution for the securities on
deposit with the custodian, it will notify the depositary bank. Subject to any
restrictions imposed by German laws or regulations, upon receipt of this notice
the depositary bank will arrange for the funds to be converted into U.S. dollars
and for the distribution of the U.S. dollars to the holders.

     The conversion into U.S. dollars will take place only if practicable and if
the U.S. dollars are transferable to the U.S. The amounts distributed to holders
will be net of the fees, expenses, taxes and governmental charges payable by
holders under the terms of the deposit agreement. The depositary will apply the
same method for distributing the proceeds of the sale of any property, including
costs estimated with conversions of foreign currency into U.S. dollars (such as
undistributed rights) held by the custodian in respect of securities on deposit.

  Distributions of Deutsche Telekom Ordinary Shares

     Whenever Deutsche Telekom makes a free distribution of shares for the
securities on deposit with the custodian, it will notify the depositary bank.
Upon receipt of the notice, the depositary bank will either distribute to
holders new Deutsche Telekom ADSs representing the Deutsche Telekom ordinary
shares deposited or, with the written consent of Deutsche Telekom, modify the
ratio of Deutsche Telekom ADS to Deutsche Telekom ordinary shares, in which case
each Deutsche Telekom ADS you hold will represent rights and interests in the
additional Deutsche Telekom ordinary shares so deposited. Only whole new
Deutsche Telekom ADSs will be distributed. Fractional entitlements will be sold
and the proceeds of the sale will be distributed as in the case of a cash
distribution.

     The distribution of new Deutsche Telekom ADSs or the modification of the
Deutsche Telekom ADS-to-Deutsche Telekom ordinary share ratio upon a
distribution of Deutsche Telekom ordinary shares will be made net of the fees,
expenses, taxes and governmental charges payable by holders under the terms of
the deposit agreement. To pay the taxes or governmental charges, the depositary
bank may sell all or a portion of the new Deutsche Telekom ordinary shares so
distributed.

     No distribution of new Deutsche Telekom ADSs will be made if it would
violate a law (e.g., the U.S. securities laws) or if it is not operationally
practicable. On a distribution of new Deutsche Telekom ADSs, the depositary bank
may reasonably request an opinion of counsel regarding the need for registration
of the distribution under the U.S. Securities laws. Any such request may delay
distribution to you of new Deutsche Telekom ADSs. If the depositary bank does
not distribute new Deutsche Telekom ADSs as described above, it may sell the
Deutsche Telekom ordinary shares received and distribute the proceeds of the
sale as in the case of a distribution of cash.

  Distributions of Rights

     Whenever Deutsche Telekom intends to distribute rights to purchase
additional Deutsche Telekom ordinary shares, it may give prior notice to the
depositary bank and may assist the depositary bank in determining whether it is
lawful and reasonably practicable to distribute rights to purchase additional
Deutsche Telekom ADSs to holders.

     The depositary bank will establish procedures to distribute rights to
purchase additional Deutsche Telekom ADSs to holders and to enable holders to
exercise their rights if it is lawful and reasonably practicable to make the
rights available to holders of Deutsche Telekom ADSs, and if Deutsche Telekom
                                       208
<PAGE>   227

provides all of the documentation contemplated in the deposit agreement (such as
opinions to address the lawfulness of the transaction). You may have to pay
fees, expenses, taxes and other governmental charges to subscribe for the new
Deutsche Telekom ADSs upon the exercise of your rights. The depositary bank is
not obligated to establish procedures to facilitate the distribution and
exercise by holders of rights to purchase new Deutsche Telekom ordinary shares
directly rather than new Deutsche Telekom ADSs.

     The depositary bank will not distribute the rights to you if:

     - Deutsche Telekom does not request that the rights be distributed to you
       or if it asks that the rights not be distributed to you; or

     - Deutsche Telekom fails to deliver satisfactory documents to the
       depositary bank; or

     - it is not reasonably practicable to distribute the rights.

     The depositary bank will sell the rights that are not exercised or not
distributed if the sale is lawful and reasonably practicable. The proceeds of
the sale will be distributed to holders as in the case of a cash distribution.
If the depositary bank is unable to sell the rights, it will allow the rights to
lapse.

  Elective Distributions

     Whenever Deutsche Telekom intends to distribute a dividend payable at the
election of shareholders either in cash or in additional Deutsche Telekom
ordinary shares, it will give prior notice thereof to the depositary bank and
will indicate whether it wishes the elective distribution to be made available
to you. In such case, Deutsche Telekom will assist the depositary bank in
determining whether the distribution is lawful and reasonably practical.

     The depositary bank will make the election available to you only if it is
reasonably practical and if Deutsche Telekom has provided all of the
documentation contemplated in the deposit agreement. In such case, the
depositary bank will establish procedures to enable you to elect to receive
either cash or additional Deutsche Telekom ADSs, in each case as described in
the deposit agreement.

     If the election is not made available to you, you will receive either cash
or additional Deutsche Telekom ADSs, depending on what a shareholder in Germany
would receive for failing to make an election, as more fully described in the
deposit agreement.

  Other Distributions

     Whenever Deutsche Telekom intends to distribute property other than cash,
Deutsche Telekom ordinary shares or rights to purchase additional Deutsche
Telekom ordinary shares, it will notify the depositary bank in advance and will
indicate whether it wishes the distribution to be made to you. If so, Deutsche
Telekom will assist the depositary bank in determining whether the distribution
to holders is lawful and reasonably practicable.

     If it is reasonably practicable to distribute the property to you, and if
Deutsche Telekom provides all of the documentation contemplated in the deposit
agreement, the depositary bank will distribute the property to the holders in a
manner it deems practicable.

     The depositary bank will make the distribution net of fees, expenses, taxes
and governmental charges payable by holders under the terms of the deposit
agreement. In order to pay the taxes and governmental charges, the depositary
bank may sell all or a portion of the property received.

     The depositary bank will not distribute the property to you and will sell
the property if:

     - Deutsche Telekom does not request that the property be distributed to you
       or if it asks that the property not be distributed to you; or

     - Deutsche Telekom fails to deliver satisfactory documents to the
       depositary bank; or

                                       209
<PAGE>   228

     - The depositary bank determines that all or a portion of the distribution
       to you is not reasonably practicable.

     The depositary bank will distribute the proceeds of the sale to holders as
in the case of a cash distribution.

CHANGES AFFECTING SHARES

     The Deutsche Telekom ordinary shares held on deposit for your Deutsche
Telekom ADSs may change from time to time. For example, there may be a change in
nominal or par value, a split-up, consolidation or reclassification of the
Deutsche Telekom ordinary shares or a recapitalization, reorganization, merger,
consolidation or sale of assets.

     If any such change were to occur, your Deutsche Telekom ADSs would, to the
extent permitted by law, represent the right to receive the property received or
exchanged in respect of the shares held on deposit. The depositary bank may in
such circumstances deliver new Deutsche Telekom ADSs to you or call for the
exchange of your existing Deutsche Telekom ADSs for new Deutsche Telekom ADSs
and will do so upon request of Deutsche Telekom to the extent legally permitted.
If the depositary bank may not lawfully distribute the property to you, the
depositary bank may sell the property and distribute the net proceeds to you as
in the case of a cash distribution.

ISSUANCE OF DEUTSCHE TELEKOM ADSS UPON DEPOSIT OF DEUTSCHE TELEKOM ORDINARY
SHARES

     The depositary bank may create Deutsche Telekom ADSs on your behalf if you
deposit Deutsche Telekom ordinary shares with the custodian. The depositary bank
will deliver these Deutsche Telekom ADSs to the person you indicate only after
you pay any applicable issuance fees and any charges and taxes payable for the
transfer of the Deutsche Telekom ordinary shares to the custodian. Your ability
to deposit Deutsche Telekom ordinary shares could be limited by German legal
considerations at the time of deposit.

     The depositary bank may delay the issuance of ADSs until the depositary
bank or the custodian receives confirmation that all required approvals have
been given and that the Deutsche Telekom ordinary shares have been duly
transferred to the custodian. The depositary bank will only issue Deutsche
Telekom ADSs in whole numbers.

     When you deposit Deutsche Telekom ordinary shares, you will be responsible
for transferring good and valid title to the depositary bank. You will thus be
deemed to represent and warrant the following:

     - The Deutsche Telekom ordinary shares are duly authorized, validly issued,
       outstanding, fully paid, non-assessable and legally obtained.

     - All preemptive (and similar) rights, if any, with respect to the Deutsche
       Telekom ordinary shares have been validly waived or exercised.

     - You are authorized to deposit the Deutsche Telekom ordinary shares.

     - The shares presented for deposit are free and clear of any lien,
       encumbrance, security interest, or other adverse claim, and are not, and
       the Deutsche Telekom ADSs issuable upon the deposit are not, subject to
       any other restriction on sale, transfer or deposit under the laws of the
       United States, the Federal Republic of Germany, or under a shareholders'
       agreement, or the Articles of Association, or any applicable regulations
       of any securities exchange.

     If any of the representations or warranties are incorrect in any way,
Deutsche Telekom and the depositary bank may, at your cost and expense, take any
and all actions necessary to correct the consequences of the misrepresentations.

WITHDRAWAL OF DEUTSCHE TELEKOM ORDINARY SHARES UPON CANCELLATION OF DEUTSCHE
TELEKOM ADSS

     As a holder, you will be entitled to present your Deutsche Telekom ADSs to
the depositary bank for cancellation and then receive the underlying shares at
the custodian's offices. To withdraw the Deutsche
                                       210
<PAGE>   229

Telekom ordinary shares represented by your Deutsche Telekom ADSs, you will be
required to pay to the depositary the fees for cancellation of the Deutsche
Telekom ADSs and any charges and taxes payable upon the transfer of the Deutsche
Telekom ordinary shares being withdrawn. You assume the risk for delivery of all
funds and securities upon withdrawal. Once canceled, the Deutsche Telekom ADSs
will not have any rights under the deposit agreement.

     If you hold an ADR registered in your name, the depositary bank may ask you
to provide proof of identity and genuineness of any signature and certain other
documents as the depositary bank may deem appropriate before it will cancel your
Deutsche Telekom ADSs. The depositary bank may delay the withdrawal of the
Deutsche Telekom ordinary shares represented by your Deutsche Telekom ADSs until
it receives satisfactory evidence of compliance with all applicable laws and
regulations. Please keep in mind that the depositary bank will only accept
Deutsche Telekom ADSs for cancellation that represent a whole number of
securities on deposit.

     You will have the right to withdraw the securities represented by your
Deutsche Telekom ADSs at any time except in the following cases:

     - Temporary delays caused by closing transfer books of the depositary or
       Deutsche Telekom in connection with voting at a shareholders' meeting or
       the payment of dividends.

     - Obligations to pay fees, taxes and similar charges.

     - Restrictions imposed because of laws or regulations applicable to
       Deutsche Telekom ADSs or the withdrawal of securities on deposit.

     The deposit agreement may not be modified to impair your right to withdraw
the securities represented by your Deutsche Telekom ADSs except to comply with
mandatory provisions of law.

VOTING RIGHTS

     As a holder, you generally have the right under the deposit agreement to
instruct the depositary bank to exercise the voting rights for the Deutsche
Telekom ordinary shares represented by your Deutsche Telekom ADSs. At Deutsche
Telekom's request, the depositary bank will mail to you any notice of
shareholders' meeting received from Deutsche Telekom together with information
explaining how to instruct the depositary bank to exercise the voting rights of
the securities represented by Deutsche Telekom ADSs. If the depositary bank
timely receives voting instructions from a holder of Deutsche Telekom ADSs, it
will endeavor to vote the securities represented by the holder's Deutsche
Telekom ADSs in accordance with the voting instructions.

     Please note that the ability of the depositary bank to carry out voting
instructions may be limited by practical and legal limitations and the terms of
the securities on deposit (including Deutsche Telekom's Articles of
Association). Deutsche Telekom cannot assure you that you will receive voting
materials in time to enable you to return voting instructions to the depositary
bank in a timely manner. Securities for which no voting instructions have been
received will not be voted.

FEES AND CHARGES

     As a Deutsche Telekom ADS holder, you will be required to pay the following
service fees to the depositary bank:

     As a Deutsche Telekom ADS holder you will also be responsible to pay
certain fees and expenses incurred by the depositary bank and certain taxes and
governmental charges such as:

     - Fees for the transfer and registration of Deutsche Telekom ordinary
       shares that the registrar and transfer agent charge for the transfer and
       registration of Deutsche Telekom ordinary shares in Germany (i.e., upon
       deposit and withdrawal of Deutsche Telekom ordinary shares).

     - Expenses incurred for converting foreign currency into U.S. dollars or
       for the sale of property.

     - Expenses for cable, telex and fax transmissions and for delivery of
       securities.

     - Taxes and duties upon the transfer of securities (i.e., when Deutsche
       Telekom ordinary shares are deposited or withdrawn from deposit).

     Deutsche Telekom has agreed to pay certain other charges and expenses of
the depositary bank. Note that the fees and charges you may be required to pay
may vary over time and may be changed by Deutsche Telekom and by the depositary
bank. You will receive prior notice of any changes.

NOTIFICATION REQUIREMENTS

     As a holder of Deutsche Telekom ADSs, you agree to comply with provisions
of German law relating to reporting of large positions in Deutsche Telekom
shares. For a description of these legal provisions, see "Description of
Deutsche Telekom Ordinary Shares -- Notification Requirements." You also agree
to provide certain information if reasonably requested by the depositary bank or
Deutsche Telekom.

AMENDMENTS AND TERMINATION

     Deutsche Telekom may agree with the depositary bank to modify the deposit
agreement at any time without your consent. Any modification that would
prejudice any of the substantial rights of holders under the deposit agreement
(except in very limited circumstances enumerated in the deposit agreement) will
not become effective until 60 days after notice has been given to the holders.
Among the modifications that Deutsche Telekom will not consider to be materially
prejudicial to your substantial rights are:

     - any modifications or supplements that are reasonably necessary for the
       Deutsche Telekom ADSs to be registered under the Securities Act or to be
       eligible for book-entry settlement, in each case without imposing or
       increasing the fees and charges you are required to pay, and

     - any modifications or supplements that are required to accommodate
       compliance with applicable provisions of law.

     You will be bound by the modifications to the deposit agreement if you
continue to hold your Deutsche Telekom ADSs after the modifications to the
deposit agreement become effective. The deposit agreement cannot be amended to
prevent you from withdrawing the Deutsche Telekom ordinary shares represented by
your Deutsche Telekom ADSs (except as permitted by law).

     Deutsche Telekom has the right to direct the depositary bank to terminate
the deposit agreement. Similarly, the depositary bank may in certain
circumstances on its own initiative terminate the deposit agreement. In either
case, the depositary bank must give notice to the holders at least 30 days
before termination.

     Upon termination, the following will occur under the deposit agreement:

     - For a period of one year after termination, you will be able to request
       the cancellation of your Deutsche Telekom ADSs and the withdrawal of the
       Deutsche Telekom ordinary shares represented by your Deutsche Telekom
       ADSs and the delivery of all other property held by the depositary bank
       in respect of those Deutsche Telekom ordinary shares on the same terms as
       prior to the termination. During this one year period the depositary bank
       will continue to collect all distributions received on the Deutsche
       Telekom ordinary shares on deposit (i.e., dividends) but will not
       distribute the property to you until you request the cancellation of your
       Deutsche Telekom ADSs.

                                       212
<PAGE>   231

     - After the expiration of the one year period, the depositary bank may sell
       the securities held on deposit. The depositary bank will hold the
       proceeds from the sale and any other funds then held for the holders of
       Deutsche Telekom ADSs in a non-interest bearing account. At that point,
       the depositary bank will have no further obligations to holders other
       than to account for the funds then held for the holders of Deutsche
       Telekom ADSs still outstanding.

BOOKS OF DEPOSITARY

     The depositary bank will maintain Deutsche Telekom ADS holder records at
its depositary offices. You may inspect the records at the office during regular
business hours but solely for the purpose of communicating with other holders in
the interest of business matters relating to the Deutsche Telekom ADSs and the
deposit agreement.

     The depositary bank will maintain in New York facilities to record and
process the issuance, cancellation, combination, split-up and transfer of ADRs.
These facilities may be closed from time to time, to the extent not prohibited
by law.

LIMITATIONS ON OBLIGATIONS AND LIABILITIES

     The deposit agreement limits Deutsche Telekom's obligations and the
depositary bank's obligations to you. Please note the following:

     - Deutsche Telekom and the depositary bank are obligated only to take the
       actions specifically stated in the depositary agreement without
       negligence or bad faith.

     - The depositary bank disclaims any liability for any failure to carry out
       voting instructions, for any manner in which a vote is cast or for the
       effect of any vote, provided it acts in good faith and in accordance with
       the terms of the deposit agreement.

     - Deutsche Telekom and the depositary bank will not be obligated to perform
       any act that is inconsistent with the terms of the deposit agreement.

     - Deutsche Telekom and the depositary bank disclaim any liability if they
       are prevented or forbidden from acting on account of any law or
       regulation, any provision of its Articles of Association, any provision
       of any securities on deposit or by reason of any act of God or war or
       other circumstances beyond their control.

     - Deutsche Telekom and the depositary bank disclaim any liability by reason
       of any exercise of, or failure to exercise, any discretion provided for
       in the deposit agreement or in Deutsche Telekom's Articles of Association
       or in any provisions of securities on deposit.

     - Deutsche Telekom and the depositary bank further disclaim any liability
       for any action or inaction in reliance on the advice or information
       received from legal counsel, accountants, any person presenting shares
       for deposit, any holder of Deutsche Telekom ADSs or authorized
       representative thereof, or any other person believed by either Deutsche
       Telekom or the depositary bank in good faith to be competent to give the
       advice or information.

     - Deutsche Telekom and the depositary bank also disclaim any obligation to
       appear in, prosecute or defend any action, suit or other proceeding in
       respect of any deposited securities or the Deutsche Telekom ADSs, unless
       indemnity satisfactory to it against expense and liability is furnished.

     - Deutsche Telekom and the depositary bank may rely without any liability
       upon any written notice, request or other document believed to be genuine
       and to have been signed or presented by the proper parties.

PRE-RELEASE TRANSACTIONS

     The depositary bank may, in certain circumstances, issue Deutsche Telekom
ADSs before receiving a deposit of Deutsche Telekom ordinary shares or release
Deutsche Telekom ordinary shares before receiving
                                       213
<PAGE>   232

Deutsche Telekom ADSs. These transactions are commonly referred to as
"pre-release transactions." The deposit agreement limits the aggregate size of
pre-release transactions and imposes a number of conditions on the transactions
(such as the need to receive collateral, the type of collateral required and the
representations required from brokers). The depositary bank may retain the
compensation received from the pre-release transactions. Full collateralization
is a precondition to the pre-release of Deutsche Telekom ADSs or underlying
Deutsche Telekom ordinary shares.

TAXES

     You will be responsible for the taxes and other governmental charges
payable on the ADRs, the Deutsche Telekom ADSs evidenced by the ADRs and the
securities represented by the Deutsche Telekom ADSs. Deutsche Telekom, the
depositary bank and the custodian may deduct from any distribution the taxes and
governmental charges payable by holders and may sell any and all property on
deposit to pay the taxes and governmental charges payable by holders. You will
be liable for any deficiency if the sale proceeds do not cover the taxes that
are due.

     The depositary bank may refuse to issue Deutsche Telekom ADSs, to deliver,
transfer, split and combine ADRs or to release securities on deposit until all
taxes and charges are paid by the applicable holder. The depositary bank and the
custodian may take reasonable administrative actions to obtain tax refunds and
reduced tax withholding for any distributions on your behalf. However, you may
be required to provide to the depositary bank and to the custodian proof of
taxpayer status and residence and the other information as the depositary bank
and the custodian may require to fulfill legal obligations. You are required to
indemnify Deutsche Telekom, the depositary bank and the custodian for any claims
with respect to taxes based on any tax benefit obtained for you.

FOREIGN CURRENCY CONVERSION

     The depositary bank will arrange for the conversion into U.S. dollars of
all foreign currency received if the conversion is practical, and it will
distribute the U.S. dollars in accordance with the terms of the deposit
agreement. You may have to pay fees and expenses incurred in converting foreign
currency, such as fees and expenses incurred in complying with currency exchange
controls and other governmental requirements.

     If the conversion of foreign currency is not practical or lawful, or if any
required approvals are denied or not obtainable at a reasonable cost or within a
reasonable period, the depositary bank may take the following actions in its
discretion:

     - Convert the foreign currency to the extent practical and lawful and
       distribute the U.S. dollars to the holders for whom the conversion and
       distribution is lawful and practical.

     - Distribute the foreign currency to holders for whom the distribution is
       lawful and practical.

     - Hold the foreign currency (without liability for interest) for the
       applicable holders.

                COMPARISON OF RIGHTS OF VOICESTREAM AND POWERTEL
                 STOCKHOLDERS AND DEUTSCHE TELEKOM SHAREHOLDERS

     As a result of the Deutsche Telekom/VoiceStream merger and the Deutsche
Telekom/Powertel merger, holders of VoiceStream common shares and Powertel
common shares, other than holders of VoiceStream common shares who make an
all-cash election and receive only cash as the merger consideration, will
receive Deutsche Telekom ADSs, each representing one Deutsche Telekom ordinary
share or the right to receive one Deutsche Telekom ordinary share on deposit
with the custodian bank, or, at the election of the holder, Deutsche Telekom
ordinary shares. If the Deutsche Telekom/VoiceStream merger is terminated and
the VoiceStream/Powertel merger occurs, holders of Powertel common shares will
receive VoiceStream common shares. Deutsche Telekom is a company incorporated
under the laws of Germany. Each of VoiceStream and Powertel is a corporation
incorporated in Delaware. The following is a summary comparison of material
differences between the rights of a VoiceStream stockholder, a Powertel
stockholder and a Deutsche Telekom shareholder arising from the differences
between the corporate laws of Delaware and those of Germany, the governing
organizational instruments of the three companies and the securities laws and
regulations governing the three companies. This summary is not a complete
description of the laws of Delaware or of Germany, the other rules or laws
referred to in this summary, VoiceStream's certificate of incorporation,
VoiceStream's bylaws, Powertel's certificate of incorporation, Powertel's bylaws
or Deutsche Telekom's memorandum and articles of association. For information on
how to obtain the governing organizational instruments of VoiceStream, Powertel
and Deutsche Telekom, see "Summary -- Where You Can Find More Information." You
are encouraged to obtain and read these documents.

     You should refer to "Description of Deutsche Telekom American Depositary
Shares" for a description of the Deutsche Telekom ADSs and a discussion of the
ways in which the rights of holders of Deutsche Telekom ADSs may differ from
those of holders of Deutsche Telekom ordinary shares.

     If you hold shares of Deutsche Telekom, VoiceStream or Powertel through a
broker or other financial intermediary rather than directly as a person whose
name is entered in the share register of the relevant company, you must rely on
procedures established by that broker or financial intermediary in order to
assert the rights of a shareholder or stockholder against the relevant company.

                   MANAGEMENT AND DIRECTORS AFTER THE MERGERS

MANAGEMENT BOARD AND SUPERVISORY BOARD OF DEUTSCHE TELEKOM FOLLOWING THE
DEUTSCHE TELEKOM/VOICESTREAM MERGER AND THE DEUTSCHE TELEKOM/POWERTEL MERGER

     General

     As required by the German Stock Corporation Act, Deutsche Telekom has a
two-tier board system consisting of a management board and a supervisory board.
The management board is responsible for managing Deutsche Telekom and
representing Deutsche Telekom in its dealings with third parties, while the
supervisory board appoints and removes the members of the management board and
oversees the management of Deutsche Telekom. The official auditor is engaged by
the supervisory board. See "Comparison of Rights of VoiceStream and Powertel
Stockholders and Deutsche Telekom Shareholders -- Classification of the Board of
Directors".

     Management Board of Deutsche Telekom

     Pursuant to Deutsche Telekom's Articles of Association, the supervisory
board determines the size of the management board, subject to the requirement
that the management board must have at least two members. The supervisory board
may appoint a chairman of the management board as well as a deputy chairman.

     The members of the management board are appointed by the supervisory board
for a term of up to five years and they may be re-appointed or have their term
extended for one or more terms of up to five years. Under certain circumstances,
such as a material breach of duty or a bona fide vote of no confidence by the
shareholders, a member of the management board may be removed by the supervisory
board prior to the expiration of the five-year term. A member of the management
board may not deal with, or vote on, matters relating to proposals, arrangements
or contracts between himself and Deutsche Telekom.

     The management board takes action by simple majority unless otherwise
provided by law. In the event of a deadlock, the management board member in
whose area of responsibility the resolution falls has a deciding vote.

                                       247
<PAGE>   266

December 31, 1999, 39.2% of the total remuneration was paid pursuant to this
bonus arrangement. In addition, a proposal to establish a stock option program
for the members of the management board and key employees was approved at the
shareholders' meeting on May 25, 2000. For further information on this program,
see "Description of Shares -- Conditional Capital".

     Pension accruals totaling 10,967,012 euros have been established in the

     The members of Deutsche Telekom's management board owned a total of
approximately 4,200 Deutsche Telekom shares as of March 31, 2000.

     Supervisory Board of Deutsche Telekom

     In accordance with the German Stock Corporation Act (Aktiengesetz), the
supervisory board of Deutsche Telekom consists of twenty members, ten of whom
represent the shareholders and ten of whom represent the employees. Members of
the supervisory board may be elected for a term of up to five years. The
supervisory board members representing the shareholders are elected at the
General Meeting of the shareholders. Most of the current supervisory board
members representing employees were elected on October 2, 1997 by the employees
in accordance with the provisions of the Co-Determination Act of 1976
(Mitbestimmungsgesetz). In this election procedure, employees elect ten
representatives made up of workers, regular employees, senior management
employees and three union representatives. Under the law that governed the
conversion of Deutsche Telekom to a stock corporation, civil servants, who are
not covered by the Co-Determination Act, are included in these groups according
to their occupations for purposes of these elections.

     The supervisory board must meet at least twice in each half year. To
achieve a quorum, at least ten of the members of the supervisory board must be
present or cast their votes in writing. Except in situations in which a
different majority is required by law, the supervisory board takes decisions by
simple majority of the votes cast. If, in the event of a deadlock, a second vote
again results in a tie, the chairman of the supervisory board can cast a
deciding vote.

     The supervisory board has formed several committees including a mediation
committee, a personnel committee for extraordinary matters and a presiding
committee. All committees have an equal number of shareholder representatives
and employee representatives. The chairman of the supervisory board is the
chairman of the mediation committee and the presiding committee where he has the
deciding vote in case of a tie. In the other committees, the chairman does not
have the deciding vote in case of a tie. The chairman of the personnel committee
is a representative of the employees.

     The first election of shareholder representatives to the supervisory board
took place at the shareholders' meeting in July 1996. Since then, further
elections have taken place to fill vacancies of the supervisory board. The terms
of office of the shareholder representatives will expire at the end of the
shareholders' meeting at which the shareholders discharge the supervisory board
members in respect of the financial year 2000, which is expected to occur in
2001. The terms of office of the employee representatives on the supervisory
board expire in 2002 upon the election of new employee representative in
accordance with the Co-Determination Act.

               STOCKHOLDER PROPOSALS FOR THE 2001 ANNUAL MEETING
                          OF VOICESTREAM STOCKHOLDERS

     VoiceStream will hold an annual meeting in the year 2001 only if the
Deutsche Telekom/VoiceStream merger has not already been completed. If the 2001
annual meeting is held, stockholders' proposals will be eligible for
consideration for inclusion in the proxy statement for that annual meeting if
those proposals are received by VoiceStream within a reasonable time before the
solicitation of proxies for the 2001 annual meeting is made. Any stockholder
proposal or notice should be directed to the attention of the Secretary,
VoiceStream Wireless Corporation, 3650 131st Avenue SE, Bellevue, Washington
98006.

               STOCKHOLDER PROPOSALS FOR THE 2001 ANNUAL MEETING
                            OF POWERTEL STOCKHOLDERS

     If either the Deutsche Telekom/Powertel merger or the VoiceStream/Powertel
merger is completed as expected, Powertel will not hold an annual meeting of
Powertel stockholders in 2001. If neither the Deutsche Telekom/Powertel merger
nor the VoiceStream/Powertel merger is completed for any reason, Powertel
expects to hold its 2001 annual meeting of stockholders in May 2001. To enable
management to analyze and respond adequately to proposals and to prepare
appropriate proposals for presentation in next year's proxy statement, a
Powertel stockholder must submit his or her proposal to Powertel no later than
December 29, 2000, to the attention of the Secretary, at Powertel, Inc., 1239
O.G. Skinner Drive, West Point, Georgia 31833. Powertel stockholders may also
submit the names of individuals whom they wish to be considered by the Powertel
board of directors as nominees for directors. For each matter a stockholder
intends to bring before the meeting, their notice must include a brief
description of the business they wish to be considered, any material interest
they have in that business and the reasons for conducting that business at the
meeting. The notice must also include the stockholder's name and address and the
class and number of Powertel shares that they own. Any proposal for presentation
at Powertel's next annual meeting which is outside the process of Rule 14a-8
under the Exchange Act will be considered untimely for purposes of Rules 14a-4
and 14a-5 if Powertel receives it after March 13, 2001.

                                DEUTSCHE TELEKOM
          UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

     The following unaudited pro forma condensed combined financial statements
combine the historical consolidated balance sheets and statements of operations
of Deutsche Telekom, VoiceStream and Powertel. VoiceStream includes the pro
forma impacts of its acquisitions of Omnipoint and Aerial, which were effected
in 2000. These financial statements give effect to the VoiceStream and Powertel
mergers using the purchase method of accounting for business combinations for
both.

     We derived this information from the audited consolidated financial
statements of Deutsche Telekom, VoiceStream, Omnipoint, Aerial and Powertel for
the year ended December 31, 1999, the unaudited consolidated financial
statements of Deutsche Telekom, VoiceStream and Powertel for the six months
ended June 30, 2000 and the unaudited statements of operations of Omnipoint and
Aerial for the periods ended February 24, 2000 and May 3, 2000, respectively. As
Omnipoint and Aerial were consolidated with VoiceStream as of June 30, 2000, the
pro forma balance sheet is derived from the consolidated balance sheets of
Deutsche Telekom, VoiceStream and Powertel. This information is only a summary
and you should read it in conjunction with the historical financial statements
and related notes of Deutsche Telekom, VoiceStream, Omnipoint, Aerial and
Powertel and other information included in this filing or incorporated by
reference.

     The unaudited pro forma condensed combined statements of operations for the
six months ended June 30, 2000 and the year ended December 31, 1999 assume the
mergers were effected on January 1, 1999. The unaudited pro forma condensed
combined balance sheet as of June 30, 2000 gives effect to the VoiceStream and
Powertel mergers as if they had occurred on June 30, 2000. The VoiceStream and
Powertel balance sheets and statements of operations have been converted from
U.S. GAAP to German GAAP to be presented on a consistent basis with Deutsche
Telekom. Deutsche Telekom historically has applied U.S. GAAP accounting
principles to the extent allowable under German GAAP. Deutsche Telekom has
decided that, in preparing its German GAAP financial statements, it will
generally apply accounting principles in line with those of U.S. GAAP. Deutsche
Telekom may depart from this approach when it determines that a U.S. GAAP
treatment would likely be contrary to the general understanding of investors in
Germany. Any such departures are reflected in Deutsche Telekom's U.S. GAAP
reconciliation footnote. The differences between U.S. GAAP and German GAAP are
summarized in the accompanying Notes 21 and 26, respectively. The accounting
policies of Deutsche Telekom and VoiceStream are substantially comparable,
however, certain reclassifications have been made to VoiceStream's and
Powertel's historical presentation to conform to Deutsche Telekom's
presentation. These reclassifications do not materially impact VoiceStream's or
Powertel's results of operations or financial position for the periods
presented.

     The VoiceStream and Powertel statements of operations have been translated
to euros from U.S. dollars using average exchange rates of 1.04257 and .93879
for the six months ended June 30, 2000 and the year ended December 31, 1999,
respectively. The balance sheets have been translated to euros at the June 30,
2000 exchange rate of 1.0444.

     The unaudited pro forma condensed combined financial information is for
illustrative purposes only. Deutsche Telekom, VoiceStream, Omnipoint, Aerial and
Powertel may have performed differently had they always been combined. You
should not rely on the pro forma combined financial information as being
indicative of the historical results that would have been achieved had the
companies always been combined or the future results that the combined companies
will experience after the mergers.

Note 4

     The VoiceStream merger will result in an allocation of the purchase price
to the tangible and intangible assets and liabilities of VoiceStream. The
transaction is not expected to result in an incremental deferred tax liability.
Such allocation reflects the estimated fair value of the assets and liabilities
acquired by Deutsche Telekom based upon information available at the date of the
preparation of the accompanying pro forma condensed combined financial
statements. Such allocation will be adjusted upon the final determination of
such fair values. Management is not aware of any circumstances that would cause
the final purchase price allocation to be significantly different from that
which is reflected in the accompanying pro forma condensed combined balance
sheet. However, actual valuations and allocations may differ from those
reflected herein.

---------------
(a) The outstanding VoiceStream common shares as of June 30, 2000.

(b) Represents the conversion of the VoiceStream junior convertible preferred
    shares to VoiceStream common shares prior to the closing of the merger. The
    VoiceStream junior convertible preferred shares will be converted at 30.29
    euros ($29) per common share, pursuant to the VoiceStream preferred share
    agreement.

(c) The share price is based on the weighted average closing price of Deutsche
    Telekom ordinary shares for the three days before and after July 23, 2000,
    the VoiceStream merger measurement date.

(d) The conversion factor used for purposes of this pro forma purchase price
    allocation is the stock and cash election of 3.2 shares of Deutsche Telekom
    shares plus 31.33 euros ($30) cash for each VoiceStream common share. The
    merger agreement includes a provision which will increase the number of
    shares to be issued and decrease the cash consideration in the event the
    stock to cash mix is not adequate for the transaction to qualify as a tax
    free exchange.

    Under German GAAP, the Deutsche Telekom ordinary shares issued in
    consideration for the acquisition of VoiceStream would be valued based on
    weighted average quoted market price as of the closing date of the
    transaction. For purposes of the pro forma financial statements, the share
    price used to calculate the pro forma purchase price was the weighted
    average quoted market price for three days before and three days after July
    23, 2000, the announcement date. The actual purchase price and resultant
    goodwill could vary considerably under German GAAP due to fluctuations in
    Deutsche Telekom's share price. For example, given Deutsche Telekom's share
    price of EUR 38.97 per share as of September 29, 2000, the purchase price
    and the resultant goodwill would be reduced by approximately EUR 9.6 billion
    if this date were the transaction closing date.

Under U.S. GAAP, the share price used to value the Deutsche Telekom ordinary
shares issued is considered to be fixed based on the weighted average quoted
     market price for three days before and three days after July 23, 2000. At
     the close of this transaction, if, pursuant to the merger agreement, a
     decline in the Deutsche Telekom share price results in a revision to the
     amount of cash and/or ordinary shares issued either due to the tax-free
     exchange provisions or due to the renegotiation provisions if the share
     price declines below EUR 33, a new measurement date of the share price
     would be triggered. The effect of any remeasurement pursuant to the
     tax-free exchange or renegotiation provisions would reduce the overall
     purchase price and resultant goodwill similar to the reduction disclosed
     for German GAAP purposes.

(e) This amount represents the fair value, based on a Black-Scholes valuation,
    associated with the conversion of outstanding VoiceStream options, warrants
    and restricted shares to equivalent options, warrants and restricted shares
    of Deutsche Telekom at the time of the Deutsche Telekom/VoiceStream merger
    based on the number of options, warrants and restricted shares outstanding
    and the closing market price of Deutsche Telekom ordinary shares as of July
    23, 2000.

(f) A portion of the intrinsic value of the unvested VoiceStream options to be
    converted into Deutsche Telekom options have been recorded as deferred
    compensation and will be expensed over the remaining vesting period.

(g) Anticipated merger costs to be capitalized by Deutsche Telekom as a result
    of the Deutsche Telekom/VoiceStream merger represent banker's fees.

(h) We have assumed the fair market value of tangible assets is equal to net
    book value pending finalization of the purchase price allocation process.

(i) The estimated fair value of the VoiceStream intangible assets acquired,
    based on preliminary valuations, are as follows:

(j) Certain of VoiceStream's long-term debt agreements contain provisions which
    could require VoiceStream to repay the debt upon a change in control.

    The 4.44 billion euros senior secured credit facility (the "Credit
    Facility") contains a provision whereby a change in control, together with
    an affirmative vote of the majority of the lenders within 90 days after the
    change in control occurs, constitutes an event of default. If the event of
    default is declared, all principal and interest under the Credit Facility
    becomes due and payable immediately. At June 30, 2000 approximately 2.86
    billion euros was outstanding under the credit facility.

    The 10 3/8% Senior Notes, the 11 1/2% Senior Notes and the 11 7/8% Senior
    Discount Notes (collectively the "Notes") contain provisions whereby a
    change in control, together with a rating decline of the Notes would
    constitute a change in control triggering event. If such an event occurs,
    the holders of the Notes can require VoiceStream to repurchase the Notes,
    within 90 days of the occurrence of the event, at the greater of: (I) 101%
    plus unpaid interest, and (II) the sum of the present values of the

    remaining scheduled payments of principal and interest. At June 30, 2000
    approximately 2.44 billion euros in Notes were outstanding.

    The pro forma condensed balance sheet assumes that the change in control
    will not result in the repayment of the debt outstanding under these
    agreements, and therefore, outstanding debt amounts have not been
    reclassified as current.

(k) The actual consideration and resulting goodwill for the VoiceStream merger
    could increase due to the exercise of stock options, warrants, put options
    or conversion of remaining outstanding preferred shares. Exercise or
    conversion of all of these financial instruments would result in
    approximately 97.9 million additional Deutsche Telekom shares being issued,
    7.2 billion euros of additional consideration and goodwill and additional
    amortization expense of approximately 89.9 million euros for the six months
    ended June 30, 2000 and 179.8 million euros for the year ended December 31,
    1999. If such financial instruments are not exercised or converted, the
    agreement stipulates that these financial instruments will be converted into
    equivalent Deutsche Telekom convertible securities.

Note 14

     The Powertel merger will result in an allocation of the purchase price to
the tangible and intangible assets and liabilities of Powertel. The transaction
is not expected to result in an incremental deferred tax liability. The
allocation reflects the estimated fair value of the assets and liabilities
acquired by Deutsche Telekom based upon information available at the date of the
preparation of the accompanying pro forma condensed combined financial
statements and will be adjusted upon the final determination of such fair
values. Management is not aware of any circumstances that would cause the final
purchase price allocation to be significantly different from that which is
reflected in the accompanying pro forma condensed combined balance sheet.
However, actual valuations and allocations may differ from those reflected
herein.

     Under German GAAP, the aggregate purchase price was calculated as follows:

(a) The outstanding Powertel common and restricted shares as of June 30, 2000.

(b) These shares relate to the Powertel preferred shares which will be converted
    into Deutsche Telekom ordinary shares as part of the merger.

(c) Pursuant to the merger agreement the exchange ratio is 2.6353 Deutsche
    Telekom ordinary shares for each Powertel share.

(d) The share price is based on the weighted average closing price of Deutsche
    Telekom ordinary shares for the three days before and after August 28, 2000,
    the Powertel merger measurement date.

    Under German GAAP, the Deutsche Telekom ordinary shares issued in
    consideration for the acquisition of Powertel would be valued based on
    weighted average quoted market price as of the closing date of the
    transaction. For purposes of the pro forma financial statements, the share
    price used to calculate the pro forma purchase price was a weighted average
    quoted market price for three days before and three days after August 28,
    2000, the announcement date. The actual purchase price

                    (IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)

and resultant goodwill could vary considerably under German GAAP due to
fluctuations in Deutsche Telekom's share price. For example, given Deutsche
     Telekom's share price of EUR 38.97 per share as of September 29, 2000, the
     purchase price and the resultant goodwill would be reduced by approximately
     EUR 1.3 billion if this date were the transaction closing date.

(e) This amount represents the fair value, based on a Black-Scholes valuation of
    Deutsche Telekom options and warrants to be issued in exchange for
    outstanding Powertel options and warrants at the time of the Deutsche
    Telekom/Powertel merger. The calculation is based on the number of Powertel
    options and warrants outstanding, the exchange ratio as defined above, and
    the share price of Deutsche Telekom common shares.

(f) Anticipated merger costs to be capitalized by Deutsche Telekom as a result
    of the Deutsche Telekom/Powertel merger primarily represents banker's fees.

(g) Certain of the long-term debt agreements of Powertel contain provisions
    which require Powertel to offer repayment of outstanding amounts when a
    change of control occurs. Additionally, the holders of the debt issued under
    certain of these agreements are entitled to a prepayment premium. The pro
    forma condensed combined balance sheet assumes that the lenders will not
    exercise the offer for Powertel to repay amounts outstanding, and therefore,
    no outstanding debt amounts have been reclassified as current. The aggregate
    amount of principal maturities (including prepayment premiums, if any) of
    Powertel's long-term debt at June 30, 2000, should the holders accept the
    offer of repayment, is approximately 1.0 billion euros. It is assumed that
    the offer to repurchase would commence within 30 days of the completion of
    the Deutsche Telekom/Powertel merger.

(h) We have assumed the fair market value of tangible assets is equal to net
    book value pending finalization of the purchase price allocation process.

(i) A portion of the intrinsic value of the unvested Powertel options to be
    converted into Deutsche Telekom options for which performance of future
    service is required has been recorded as deferred compensation and will be
    expensed over the remaining vesting period.

(j) The actual purchase price for the Powertel merger could increase due to the
    exercise of options and warrants. Exercise of all of these financial
    instruments would result in approximately 8.1 million Deutsche Telekom
    shares being issued, 183.3 million euros of additional consideration and
    goodwill and additional amortization expense of approximately 2.3 million
    euros for the six months ended June 30, 2000 and 4.6 million euros for the
    year ended December 31, 1999.

(a) Deutsche Telekom's German to U.S. GAAP reconciling items are derived from

    statements for the six months ended June 30, 2000 incorporated by reference
    in this document.

(b) Under German GAAP, internal software development costs are not capitalized.
    This adjustment capitalizes and amortizes costs capitalizable for U.S. GAAP
    purposes.

(c) Under German GAAP, maintenance accruals are recorded for costs to be
    incurred in future periods. These accruals were reversed for U.S. GAAP
    purposes.

(d) Under German GAAP, financing costs are expensed as incurred. This adjustment
    is to defer and amortize financing costs over the term of the loan for U.S.
    GAAP purposes.

(e) Under German GAAP, interest related to construction projects is not
    capitalized. Under U.S. GAAP, interest costs would be capitalized as part of
    the asset being constructed.

(f) Under German GAAP, license amortization commences on the date the license is
    acquired. Under U.S. GAAP, amortization of these licenses would commence
    upon the license being placed into

    service. This adjustment reverses the amortization expense recognized under
    German GAAP during the non-operational period of the license.

(g) This adjustment to goodwill reflects the asset and liability basis
    differences between German GAAP and U.S. GAAP.

(h) Under German GAAP, the gain from the Powertel sales-leaseback transaction
    would be recognized immediately, whereas under U.S. GAAP, gains on
    sales-leaseback transactions can be deferred under certain circumstances.
    This adjustment defers the gain recognized under German GAAP.

(i) For U.S. GAAP purposes, the gain deferred by Powertel is not valued in the
    purchase price allocation as it provides no future benefit.

(j) Under German GAAP, minority interest and mandatorily redeemable securities
    are included in shareholders' equity. For U.S. GAAP purposes, these items
    are classified as mezzanine on the balance sheet.

(k) Under U.S. GAAP, preferred shares that are mandatorily redeemable are
    excluded from shareholders' equity. Under German GAAP, these financial
    instruments are classified as equity. Additionally, these preferred shares
    are assumed to be converted for pro forma purposes and have been eliminated
    to reconcile the U.S. GAAP pro forma shareholders' equity to the German GAAP
    pro forma shareholders' equity.

Note 22

     As discussed in Notes 12 and 14(i), Deutsche Telekom has recorded as
deferred compensation expense a portion of the intrinsic value of the unvested
stock options for which future service is required related to the unvested
portion of stock options issued as part of the mergers of VoiceStream and
Powertel. This expense is being recognized over the remaining future vesting
periods of the VoiceStream and Powertel grants estimated to be an average of 2.5
years.

     Additionally, as part of the VoiceStream and Powertel merger agreements,
Deutsche Telekom has agreed to pay existing management and employee retention
and incentive bonuses, currently estimated to be 150 million euros. Since these
costs are non-recurring in nature, no associated compensation expense has been
recognized in the pro forma statements of operations.

Note 23

     This adjustment represents additional depreciation and amortization expense
recognized as part of the purchase price allocation to tangible and intangible
assets. These tangible and intangible assets are being amortized over useful
lives ranging from 3 to 40 years.

Note 24

     As disclosed in Note 7 above, Deutsche Telekom obtained financing to fund
the cash portion of the VoiceStream merger consideration. The pro forma
adjustment represents additional interest expense that would have been incurred
had the merger occurred at the beginning of the period. Interest expense was
calculated using Deutsche Telekom's weighted average borrowing rate of 7.41%.

(a) Deutsche Telekom's German to U.S. GAAP reconciling items are derived from
    Note 36 of the Deutsche Telekom consolidated financial statements for the
    year ended December 31, 1999 and Note 19 of the Deutsche Telekom unaudited
    interim consolidated financial statements for the six months ended June 30,
    2000, incorporated by reference in this document.

(b) Under German GAAP, internal software development costs are not capitalized.
    This adjustment capitalizes and amortizes costs capitalizable for U.S. GAAP
    purposes.

(c) Under German GAAP, financing costs are expensed as incurred. This adjustment
    is to defer and amortize financing costs over the term of the loan for U.S.
    GAAP purposes.

(d) Under German GAAP, interest is not capitalized related to construction
    projects. Under U.S. GAAP interest costs are capitalized as part of the
    asset being constructed.

(e) Under German GAAP, license amortization commences on the date the license is
    acquired. Under U.S. GAAP, amortization of these licenses would commence
    upon the asset being placed into service. This adjustment reverses the
    amortization expense recognized under German GAAP during the non-
    operational period of the license.

(f) The adjustment to goodwill reflects the asset and liability basis
    differences between German GAAP and U.S. GAAP.

(g) Under German GAAP, the gains from the Powertel sales-leaseback transaction
    would be recognized immediately whereas under U.S. GAAP, gains on
    sales-leaseback transactions can be deferred under certain circumstances.
    This adjustment defers the gain recognized for German GAAP purposes.

(h) For U.S. GAAP purposes, the gain recognized by Powertel is not valued in the
    purchase price allocation as it provides no future benefit.

(a) These columns reflect VoiceStream's historical consolidated statements of
    operations for the six months ended June 30, 2000 and for the year ended
    December 31, 1999. The statement of operations for the year ended December
    31, 1999 has been adjusted for interest and financing expenses that would
    have been incurred due to the increase in borrowings related to the total
    $150 million investment in Omnipoint made by VoiceStream during 1999 at a
    market interest rate of 10.3%. This adjustment assumes that VoiceStream
    purchased Omnipoint Series A preferred shares as of January 1, 1999 and
    incurred interest expense due to an increase in borrowing to fund the
    purchase.

(b) These columns reflect the historical statements of operations of Omnipoint
    for the period ended February 24, 2000 and for the year ended December 31,
    1999, respectively, adjusted for the deconsolidation of certain operations
    contributed to two joint venture entities ("CIVS II" and "CIVS III")
    immediately prior to the merger with VoiceStream. The joint ventures are
    owned 49.9% by VoiceStream and as such have been accounted for under the
    equity method.

     Certain reclassifications have been made to the historical financial
     information for Omnipoint to conform to VoiceStream's financial statement
     presentation. These reclassifications do not materially impact Omnipoint's
     results of operations.

(c) These columns reflect the historical statements of operations of Aerial for
    the period ended May 3, 2000 and the year ended December 31, 1999,
    respectively. The statements of operations have been adjusted to reflect
    certain debt conversions, repayments and equity investments between Aerial,
    its subsidiary, Aerial Operating Corporation, its parent, Telephone & Data
    Systems, and Sonera, which occurred in connection with the
    VoiceStream/Aerial merger.

    Certain reclassifications have been made to the historical financial
    information for Aerial to conform to VoiceStream's financial statement
    presentation. These reclassifications do not materially impact Aerial's
    financial position or results of operations.

(d) Represents additional costs recorded as a result of modifications made to
    stock option agreements for an officer of Omnipoint.

(e) Represents the amortization of the additional purchase price allocated to
    FCC licenses and goodwill of Omnipoint and Aerial offset by a reduction in
    depreciation expense as a result of the write-down to fair value of fixed
    assets acquired in the Omnipoint and Aerial mergers. FCC licenses are
    amortized over a 40 year period and goodwill is amortized over a 20 year
    period.

(f) Represents the amortization of the difference between the underlying net
    book value of the investments in CIVS II and CIVS III and the fair value
    assigned to these investments at the time of the Omnipoint merger. This
    difference has been allocated to FCC licenses and goodwill and is being
    amortized over 40 years and 20 years, respectively.

(g) Represents dividends related to Omnipoint 7% convertible preferred shares
    which are reflected as minority interest expense by VoiceStream as a result
    of the Omnipoint merger.

     Pro forma EBITDA, under German GAAP, represents the pro forma operating
income before net interest, taxation, depreciation and amortization, net income
(loss) from equity investments, and write-downs on financial assets and
marketable securities. Pro forma EBITDA should not be considered in isolation as
an alternative to net income, operating income or any other measure of
performance under German or U.S. GAAP. Management believes EBITDA is a relevant
measurement utilized by the telecommunications industry to assess performance
which attempts to eliminate variances caused by the effects of differences in
taxation, the amount and types of capital employed and depreciation and
amortization policies. Pro forma EBITDA also provides meaningful additional
information about the company's operating results and on its ability to service
its long-term debt and other fixed obligations and to fund its continuing
growth. Because pro forma EBITDA is not calculated in the same manner by all

          UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

     The following unaudited pro forma condensed combined financial statements
combine the historical consolidated balance sheets of VoiceStream and Powertel
and statements of operations of VoiceStream, Omnipoint, Aerial and Powertel.
These financial statements give effect to the VoiceStream/Powertel merger using
the purchase method of accounting for a business combination.

     We derived this information from the audited consolidated financial
statements of VoiceStream, Omnipoint, Aerial and Powertel for the year ended
December 31, 1999, the unaudited consolidated financial statements of
VoiceStream and Powertel for the six months ended June 30, 2000 and the
unaudited financial statements of Omnipoint and Aerial for the periods ended
February 24, 2000 and May 3, 2000, respectively. This information is only a
summary and you should read it in conjunction with the historical financial
statements and related notes of VoiceStream, Omnipoint, Aerial and Powertel and
other information included in this filing or incorporated by reference.

     The unaudited pro forma condensed combined statements of operations for the
year ended December 31, 1999 and the six months ended June 30, 2000 assume the
VoiceStream mergers with Omnipoint, Aerial and Powertel were effected on January
1, 1999. The unaudited pro forma condensed combined balance sheet as of June 30,
2000 gives effect to the Powertel merger as if it had occurred on June 30, 2000.
The accounting policies of VoiceStream, Omnipoint, Aerial and Powertel are
substantially comparable. Certain reclassifications have been made to Omnipoint,
Aerial and Powertel's historical presentations to conform to VoiceStream's
presentation. These reclassifications do not materially impact the companies'
results of operations or financial position for the periods presented.

     We are providing the unaudited pro forma condensed combined financial
information for illustrative purposes only. The companies may have performed
differently had they always been combined. You should not rely on the pro forma
combined financial information as being indicative of the historical results
that would have been achieved had the companies always been combined or the
future results that the combined companies will experience after the merger.

Note 1

     These columns reflect VoiceStream's consolidated historical balance sheet
and statement of operations as of and for the six months ended June 30, 2000 and
the statement of operations for the year ended December 31, 1999. The December
31, 1999 statement of operations has been adjusted for interest and financing
expenses that would have been incurred due to the increase in borrowings related
to the total $150 million investment in Omnipoint made by VoiceStream during
1999 at a market interest rate of 10.3%. This adjustment assumes that
VoiceStream purchased Omnipoint Series A preferred shares as of January 1, 1999
and incurred interest expense due to an increase in borrowings to fund such
purchase.

     The balance sheet has been adjusted to reflect the $5 billion investment in
VoiceStream convertible voting preferred shares by Deutsche Telekom on September
6, 2000. The preferred shares are convertible to VoiceStream common shares at
Deutsche Telekom's option at a price of $160 per share if the proposed merger
between Deutsche Telekom and VoiceStream is terminated. If Deutsche Telekom
converted these preferred shares to VoiceStream common shares an additional
31,250,000 VoiceStream common shares would have been outstanding. On a pro forma
basis the loss per share would have been as follows:

     As discussed above, on February 25, 2000 and May 4, 2000, VoiceStream
completed mergers with Omnipoint and Aerial, respectively. Pursuant to the
Omnipoint agreement, VoiceStream exchanged 0.825 of a share of VoiceStream
common stock plus $8.00 in cash for each outstanding Omnipoint common share.
Pursuant to the Aerial agreement, VoiceStream exchanged 0.455 of a VoiceStream
common share for each outstanding Aerial common share.

     The components of the purchase price of these merger transactions and the
preliminary allocations are as follows (in thousands):

     The above allocations reflect the estimated fair value of assets and
liabilities acquired. Some allocations are based on valuations, which have not
been finalized. VoiceStream does not believe that the final purchase price
allocations will produce materially different results than those reflected
above.

respectively adjusted for the deconsolidation of certain operations that were
contributed to CIVS II and CIVS III immediately prior to the merger with
VoiceStream. These joint ventures are owned 49.9% by VoiceStream and as such
have been accounted for under the equity method.

     Certain reclassifications have been made to the historical financial
information for Omnipoint to conform to VoiceStream's financial statement
presentation. These reclassifications do not materially impact Omnipoint's
results of operations.

     These columns reflect the historical statements of operations of Aerial for
the period ended May 3, 2000 and the year ended December 31, 1999, respectively.
The statements of operations have been adjusted to reflect certain debt
conversions, repayments and equity investments between Aerial, its subsidiary,
Aerial Operating Corporation, its parent, Telephone & Data Systems, and Sonera,
which occurred in connection with the VoiceStream/Aerial merger on May 4, 2000.

     Certain reclassifications have been made to the historical financial
information for Aerial to conform to VoiceStream's financial statement
presentation. These reclassifications do not materially impact Aerial's
financial position or results of operations.

Note 5

     The Powertel merger will result in an allocation of the purchase price to
the tangible and intangible assets and liabilities of Powertel. The transaction
is not expected to result in an incremental deferred tax liability. The
allocation reflects the estimated fair value of the assets and liabilities
acquired by VoiceStream based upon information available at the date of the
preparation of the accompanying pro forma condensed combined financial
statements and will be adjusted upon final determination of such fair values.
Management is not aware of any circumstances that would cause the final purchase
price allocation to be significantly different from that which is reflected in
the accompanying pro forma condensed combined balance sheet. However, the actual
purchase price will differ based on any change in VoiceStream's common share
price on the actual measurement date and the valuations and allocations may
differ from those reflected herein.

---------------
(a) Outstanding Powertel common shares are as of August 28, 2000, the latest
    practicable date.

(b) An additional 18.0 million common shares relate to the Powertel preferred
    shares that will be converted into VoiceStream common shares as part of the
    merger.

(c) The exchange ratio of .7261 of a VoiceStream common share for each Powertel
    share is calculated pursuant to the merger agreement based on the closing
    price of VoiceStream common shares on August 28, 2000, the latest
    practicable date, at $117.063 per share. Pursuant to the merger agreement,
    if the average of the closing prices of VoiceStream common shares on certain
    days immediately prior to the closing date is less than $113.33 per share,
    the conversion factor will be .75. If the closing price of VoiceStream
    common shares on those days is greater than $130.77 per share, the
    conversion factor will be .65.

    Based on the common shares outstanding as of August 28, 2000, should the
    final purchase price ultimately be based upon a $130.77 per share price, the
    merger consideration would increase by approximately $52 million, which
    would result in an estimated increase in annual amortization expense of $2.6
    million. Should the final purchase price ultimately be based on a $113.33
    per share price, the merger consideration would decrease by $96 million
    which would result in a decrease in annual amortization expense of $4.8
    million.

(d) This amount represents the fair value, based on a Black-Scholes valuation,
    of VoiceStream options and warrants to be issued in exchange for outstanding
    Powertel options and warrants at August 28, 2000, the latest practicable
    date. The calculation is based on the number of Powertel options and
    warrants outstanding, the exchange ratio as defined above, and the closing
    market price of VoiceStream on the Nasdaq Stock Market on that date. The
    calculation excludes a portion of the intrinsic value of unvested stock
    options for which performance of future service is required, pursuant to the
    guidelines of Financial Accounting Standards Board Interpretation Number 44
    ('FIN 44'), that has been recorded as deferred compensation (see Note 10).

Note 6

     This adjustment reflects the reversal of a deferred gain recorded on
Powertel's balance sheet from a sales-leaseback transaction, which occurred in
1999.

Note 7

     Certain of the long-term debt agreements of Powertel contain provisions
which require Powertel to offer repayment of outstanding amounts when a change
of control occurs. Additionally, the holders of the debt issued under certain of
these agreements are entitled to a prepayment premium. The pro forma condensed
combined balance sheet assumes that the lenders will not exercise the offer for
Powertel to repay amounts outstanding, and therefore, no outstanding debt
amounts have been reclassified as current. The aggregate amount of principal
maturities (including prepayment premiums, if any) of Powertel's long-term debt
at June 30, 2000, should the holders accept the offer of repayment. It is
assumed that the offer to repurchase would commence within 30 days of the
completion of the VoiceStream/Powertel merger.

Note 8

     This adjustment represents the elimination in consolidation of Powertel's
historical common shares and paid-in capital of $518.6 million, the elimination
of Powertel's historical deferred compensation of approximately $1.0 million and
the elimination of Powertel's historical accumulated deficit of $663.3 million.

Note 9

     This adjustment represents the amortization of the additional purchase
price allocated to FCC licenses and goodwill in the Powertel merger. FCC
licenses are amortized over a 40 year period and goodwill is amortized over a 20
year period.

Note 10

     Pursuant to FIN 44, VoiceStream has recorded as deferred compensation a
portion of the intrinsic value of the unvested stock options for which future
service is required as deferred compensation in shareholders' equity
(approximately $32.5 million). This balance is being recognized as compensation
expense over the remaining future vesting period of the grants.

Note 13

     This adjustment represents the amortization of the additional purchase
price allocated to FCC licenses and goodwill of Omnipoint and Aerial, offset by
a reduction in depreciation expense as a result of the write-down to fair value
of fixed assets acquired in the Omnipoint and Aerial mergers. FCC licenses are
amortized over a 40 year period and goodwill is amortized over a 20 year period.

Note 16

     As a result of the Omnipoint and Aerial mergers, and potentially the
Powertel merger,VoiceStream may have to make substantial tax indemnity payments
to Western Wireless. In the spin-off transaction effected on May 3, 1999,
Western Wireless distributed its entire 80.1% interest in VoiceStream's common
shares to its stockholders. Western Wireless will recognize gain as a result of
the spin-off, if the spin-off is considered to be part of a plan or series of
related transactions pursuant to which one or more persons acquire, directly or
indirectly, 50% or more of VoiceStream's common shares, considered under IRS
rules a "prohibited transaction". VoiceStream has agreed to indemnify Western
Wireless on an after-tax basis for any taxes, penalties, interest and various
other expenses incurred by Western Wireless if it is required to recognize such
a gain. The amount of such gain that Western Wireless would recognize would be
equal to the difference between the fair market value of VoiceStream common
shares at the time of the spin-off and Western Wireless' adjusted tax basis in
such shares at the time.

     In the absence of direct authority, and although the issue is not free from
doubt, VoiceStream believes that it should be able to establish that the
spin-off and its acquisition of shares pursuant to the mergers, in conjunction
with the related transactions and Hutchison's acquisition of its existing
VoiceStream shares within two years prior to the spin-off, are not pursuant to a
prohibited plan. However, if the IRS were to take the position that a prohibited
plan did occur, the estimated range of possible liability of VoiceStream, not
including interest and penalties, if any, is from zero to $400 million.

                          AGREEMENT AND PLAN OF MERGER

     This AGREEMENT AND PLAN OF MERGER, dated as of July 23, 2000, as amended
and restated on September 28, 2000, among Deutsche Telekom AG, an
AKTIENGESELLSCHAFT organized and existing under the laws of the Federal Republic
of Germany ("DT"), Voicestream Wireless Corporation, a Delaware corporation
("VOICESTREAM"), and Bega, Inc., a Delaware corporation formed by DT ("MERGER
SUB") (each a "PARTY" and, together, the "PARTIES").

                                  WITNESSETH:

     WHEREAS, the Management Board (VORSTAND) and the Supervisory Board
(AUFSICHTSRAT) of DT and the Board of Directors of Voicestream have determined
that it is advisable and in the best interests of their respective companies and
stockholders to consummate the strategic combination transaction provided for in
this Agreement, the stock subscription contemplated by the DT Financing
Agreements (as defined below) and the other transactions contemplated hereby in
accordance with the laws of their respective jurisdictions of organization and
have authorized the execution and delivery of this Agreement;

     WHEREAS, the Board of Directors of Merger Sub has determined that it is
advisable and in the best interests of Merger Sub and its stockholder to
consummate the strategic combination transaction provided for in this Agreement
and has authorized the execution and delivery of this Agreement, and DT, as
Merger Sub's current sole stockholder, has approved and adopted this Agreement;

     WHEREAS, simultaneously with the execution and delivery of this Agreement,
as part of a single overall transaction, and to induce DT to enter into this
Agreement, certain stockholders of Voicestream are each entering into a
Stockholders Agreement (collectively, the "STOCKHOLDERS AGREEMENTS") with DT
dated the date hereof with respect to this Agreement and the Merger (as defined
below);

     WHEREAS, simultaneously with the execution and delivery of this Agreement,
as part of a single overall transaction, and to induce Voicestream to enter into
this Agreement, DT is entering into the DT Financing Agreements as defined below
with Voicestream in the form attached hereto as Exhibit C;

     WHEREAS, for United States federal income tax purposes the parties intend
that the Merger will qualify (i) as a reorganization within the meaning of
Section 368(a) of the Code (as defined below) and (ii) for an exception to the
general rule of Section 367(a)(1) of the Code; and

     WHEREAS, DT and Voicestream desire to make certain representations,
warranties, covenants and agreements in connection with the transactions
contemplated by this Agreement.

     NOW, THEREFORE, in consideration of the foregoing and the mutual
representations, warranties, covenants and agreements herein contained, and
intending to be legally bound hereby, DT, Voicestream and Merger Sub hereby
agree as follows:

                                   ARTICLE 1

                                   THE MERGER

     SECTION 1.01.  Appointment of Escrow Agent and Formation of Merger
Sub.  (a) Merger Sub is a corporation incorporated pursuant to Delaware Law and
is a constituent company in the Merger. Except as provided in or contemplated by
the last sentence of Section 1.01(b), DT owns 100 percent of the outstanding
capital stock of Merger Sub.

     (b) As promptly as possible following the date hereof, DT shall appoint a
United States bank or trust company or other independent financial institution
in the United States reasonably satisfactory to Voicestream to act, inter alia,
as escrow agent and exchange agent for the Merger and the delivery of the Merger
Consideration (as defined below) to former stockholders of Voicestream and the
other Merger Consideration Recipients (as defined below) (the "ESCROW AGENT").
DT and Voicestream shall enter into

                                       A-1
<PAGE>   316

an Escrow Agency Agreement with the Escrow Agent based on the form attached
hereto as Exhibit F but with such changes as Voicestream and DT may agree (the
"ESCROW AGENCY AGREEMENT"), which agreement shall set forth the duties,
responsibilities and obligations of the Escrow Agent consistent with the terms
of this Agreement. Solely to accommodate the transactions described in this
Article I and subject to the terms and conditions of the Escrow Agency
Agreement, one day prior to the Effective Time DT shall cause the Escrow Agent
to be registered, as DT's fiduciary (for the period prior to the Effective Time)
as the record holder of all of the issued and outstanding shares of common
stock, par value $.000001 per share, of Merger Sub (the "MERGER SUB COMMON
STOCK").

     SECTION 1.02.  The Merger.  (a) Upon the terms and subject to the
conditions of this Agreement and in accordance with Delaware Law, on the Closing
Date (as defined below), Voicestream will cause a certificate of merger (the
"CERTIFICATE OF MERGER") to be executed and filed with the Secretary of State of
the State of Delaware and make all other filings or recordings required by
applicable law in connection with the Merger. The Merger shall become effective
at such time as the Certificate of Merger is duly filed with the Secretary of
State of the State of Delaware or at such later time as is specified in the
Certificate of Merger in accordance with Delaware Law (the "EFFECTIVE TIME").

     (b) Upon the terms and subject to the conditions set forth in this
Agreement, at the Effective Time, Merger Sub shall be merged with and into
Voicestream in accordance with Delaware Law (the "MERGER"), whereupon the
separate existence of Merger Sub shall cease, and Voicestream shall be the
surviving corporation in the Merger (the "SURVIVING CORPORATION") and shall
continue to be governed by the laws of the State of Delaware, and the separate
corporate existence of Voicestream, with all its rights, privileges, immunities,
powers and franchises, shall continue unaffected by the Merger except as set
forth in this Article I. The Merger shall have the effects specified in Delaware
Law.

     SECTION 1.03.  The Closing.  On the fifth Business Day (or such other date
as Voicestream and DT may agree) after the last to be fulfilled or waived of the
conditions set forth in Article VI hereof (other than the conditions contained
in Sections 6.02(c), 6.02(d) and 6.03(c) so long as it is reasonably apparent
that such conditions and the condition contained in Section 6.01(b) will be able
to be satisfied at the Closing) shall be fulfilled or waived in accordance with
this Agreement, the closing of the Merger (the "CLOSING") shall be held (but
only if all of the conditions set forth in Article VI shall have been satisfied
or waived prior to the Effective Time) at such time as DT and Voicestream shall
agree (the "CLOSING DATE") at the offices of Cleary, Gottlieb, Steen & Hamilton,
New York, New York or at such other place or places as DT and Voicestream may
agree.

     SECTION 1.04.  The Merger Exchange.

     (a) Upon the terms and subject to the conditions of this Agreement and the
Escrow Agency Agreement, as soon as possible after the Effective Time, (x) on
the Closing Date, the Escrow Agent shall contribute, for the account of the
former stockholders of Voicestream, all of the issued and outstanding shares of
the Surviving Corporation Common Stock (as defined below) to DT as a transfer in
kind, and (y) DT shall deliver the Merger Consideration to the Escrow Agent for
the account of (i) the former stockholders of Voicestream, (ii) the Dissenting
Stockholders Trustee (as defined in Annex 1.12(a) below), (iii) the Options
Trustee (as defined in Annex 1.08(a) below), (iv) the 7% Convertible Preferred
Shares Trustee (as defined in Annex 1.05(n)(2) below), (v) the Cook Inlet
Partners Shares Trustee (as defined in Annex 1.05(p) below)), (vi) the
Restricted Shares Trustee (as defined in Annex 1.08(b) below) and (vii) the
Warrants Trustee (as defined in Annex 1.05(o)) (collectively, the "MERGER
CONSIDERATION RECIPIENTS"). DT and the Escrow Agent shall effect the foregoing
in accordance with Sections 183 et seq. and 203 et seq. of the German Stock
Corporation Act (AKTIENGESETZ) (the "GERMAN ACT") by registering the increase of
the DT stated share capital with the commercial register (HANDELSREGISTER) for
DT (the "COMMERCIAL REGISTER") as soon as possible after the Effective Time. In
the event that, in connection with the performance of DT's obligations in this
Section 1.04(a), on or prior to the Closing Date the Management Board of DT
passes a resolution to increase the issued capital of DT in accordance with
Article 5(2) of the Articles of Association of DT by such number of shares as is
equal to the number of shares to be delivered as part of the Merger
Consideration, and the

                                       A-2
<PAGE>   317

Supervisory Board shall have consented thereto, then (i) the Escrow Agent shall
promptly subscribe for such new DT Ordinary Shares to be issued as part of the
Merger Consideration and shall promptly on the Closing Date make the
contribution to DT referred to in the first sentence of this Section 1.04(a) and
(ii) the Management Board and the chairman of the Supervisory Board shall as
soon as possible thereafter file the application for registration of the
implementation of the capital increase with the Commercial Register, with the
effect that on registration of the capital increase in the Commercial Register,
such new DT Ordinary Shares shall by operation of law be held solely by the
Escrow Agent, for delivery to and for the benefit of the Merger Consideration
Recipients. Prior to, and or immediately after or at the Effective Time, DT
shall deposit, or cause to be deposited, with the Escrow Agent for the benefit
of holders of Voicestream Common Shares in accordance with this Article I, the
Aggregate Cash Amount, or, if applicable, the Adjusted Aggregate Cash Amount. At
the Effective Time, the obligations of DT and the Escrow Agent under this
Section 1.04(a) shall be unconditional.

     (b) Each share certificate (a "CERTIFICATE") formerly representing any
Voicestream Common Shares (other than Excluded Voicestream Shares (as defined
below) and Dissenting Shares (as defined below)) shall thereafter represent only
the right to receive the Merger Consideration and the right, if any, to receive
pursuant to Section 1.09 cash in lieu of fractional DT Depositary Shares or
fractional DT Ordinary Shares, as applicable, and any dividend or distribution
pursuant to Section 1.06(f), in each case, without interest. The DT Ordinary
Shares and the DT Depositary Shares issued as provided in Section 1.05 shall be
of the same class and shall have the same rights as the currently outstanding DT
Ordinary Shares and the currently outstanding DT Depositary Shares,
respectively.

     SECTION 1.05.  Conversion and Exchange of Shares.  At the Effective Time:

     (a) Each share of common stock, par value $0.001 per share, of Voicestream
("VOICESTREAM COMMON SHARES") owned by DT or Voicestream immediately prior to
the Effective Time (each, an "EXCLUDED VOICESTREAM SHARE") shall, by virtue of
the Merger, and without any action on the part of the holder thereof, no longer
be outstanding, be canceled and retired without payment of any consideration
therefor and shall cease to exist.

     (b) Subject to the further provisions of this Section 1.05, each
Voicestream Common Share, other than Excluded Voicestream Shares and Dissenting
Shares, issued and outstanding immediately prior to the Effective Time shall by
virtue of the Merger and without any action on the part of the holder thereof,
be converted into the right to receive: (i) for each Voicestream Common Share in
respect of which an effective Election shall have been made, one of the
following: (A) a combination of $30 in cash (the "PER SHARE CASH AMOUNT") and
3.2 validly issued, fully paid and nonassessable ordinary shares of DT ("DT
ORDINARY SHARES"), subject to adjustment as provided in Section 1.05(g) (the
"MIXED CONSIDERATION"), (B) $200.00 in cash (the "CASH CONSIDERATION"), subject
to proration and/or adjustment as provided in Sections 1.05(e) and (g) or (C)
3.7647 DT Ordinary Shares (the "EXCHANGE RATIO"), subject to proration and/or
adjustment as provided in Sections 1.05(f) and (g) (the "STOCK CONSIDERATION")
and (ii) for each Voicestream Common Share in respect of which no effective
Election has been made for any reason, the Mixed Consideration. The
consideration payable pursuant to this paragraph (b) is referred to herein
collectively as the "MERGER CONSIDERATION".

     (c) For purposes of this Section 1.05, "AGGREGATE CASH AMOUNT" shall equal
the product of (1) the Per Share Cash Amount and (2) the total number of
Voicestream Common Shares outstanding immediately prior to the Effective Time.

     (d) Mixed Election.  Each record holder of Voicestream Common Shares
immediately prior to the Election Deadline who validly makes or is deemed to
have made below a mixed election (a "MIXED ELECTION") shall be entitled to
receive the Mixed Consideration for each of such holder's Voicestream Common
Shares as to which such Mixed Election is made. Mixed Elections shall be made on
a form, mutually acceptable to DT and Voicestream, designed for the purpose of
making Elections (a "FORM ELECTION") accompanied by Certificates for the
Voicestream Common Shares to which such Form of Election relates as provided in
Section 1.05(h) below.

                                       A-3
<PAGE>   318

     (e) Cash Election.  Each record holder of Voicestream Common Shares
immediately prior to the Election Deadline who validly makes a cash election (a
"CASH ELECTION") shall be entitled to receive cash or a combination of cash and
DT Ordinary Shares, solely as provided in clause (i) or (ii) below:

          (i) If (A) the product of the number of Voicestream Common Shares as
     to which a valid Cash Election is made and the Cash Consideration (such
     product being the "CASH ELECTION AMOUNT") exceeds (B) the Aggregate Cash
     Amount minus the product of the Per Share Cash Amount and the number of
     Voicestream Common Shares as to which a valid Mixed Election (including No
     Election Shares) has been made (the amount determined pursuant to this
     clause (B) being the "AVAILABLE CASH ELECTION AMOUNT"), then each
     Voicestream Common Share as to which a valid Cash Election is made shall be
     converted into the right to receive (x) an amount of cash (without
     interest) equal to the Cash Consideration multiplied by a fraction, the
     numerator of which shall be the Available Cash Election Amount and the
     denominator of which shall be the Cash Election Amount (such fraction being
     the "CASH FRACTION") and (y) a number of DT Ordinary Shares equal to the
     product of (p) the Exchange Ratio and (q) a fraction equal to one minus the
     Cash Fraction.

          (ii) If the Available Cash Amount equals or exceeds the Cash Election
     Amount, each Voicestream Common Share as to which a valid Cash Election is
     made shall be converted into the right to receive the Cash Consideration in
     cash (without interest).

Cash Elections shall be made on the Form of Election, accompanied by
Certificates for the Voicestream Common Shares to which such Form of Cash
Election relates as provided in Section 1.05(h) below.

     (f) Stock Election.  Each record holder of Voicestream Common Shares
immediately prior to the Election Deadline who validly makes a stock election (a
"STOCK ELECTION") shall be entitled to receive DT Ordinary Shares or a
combination of cash and DT Ordinary Shares, solely as provided in clause (i) or
(ii) below:

          (i) If the Available Cash Election Amount exceeds the Cash Election
     Amount, then each Voicestream Common Share as to which a valid Stock
     Election is made shall be converted into the right to receive (A) an amount
     of cash (without interest) equal to the amount of such excess divided by
     the number of Voicestream Common Shares as to which a valid Stock Election
     is made and (B) a number of DT Ordinary Shares equal to the product of (x)
     the Exchange Ratio and (y) a fraction, the numerator of which shall be $200
     minus the amount calculated in clause (A) of this paragraph and the
     denominator of which shall be $200.

          (ii) If the Cash Election Amount equals or exceeds the Available Cash
     Election Amount, each Voicestream Common Share as to which a valid Stock
     Election is made shall be converted into the right to receive the number of
     DT Ordinary Shares equal to the Exchange Ratio.

     (g) Further Adjustments.  If necessary to permit the delivery of the tax
opinion referred to in Section 6.02(d), in addition to the adjustments set forth
above, Voicestream shall, after consultation with DT, prior to the delivery of
the tax opinion referred to in Section 6.02(d), reduce (a "CASH ADJUSTMENT") the
Aggregate Cash Amount to such amount (the "ADJUSTED AGGREGATE CASH AMOUNT") as
Voicestream reasonably determines is necessary to permit the delivery of the tax
opinion referred to in Section 6.02(d) and, if Voicestream makes a Cash
Adjustment, DT shall substitute in lieu of such cash DT Common Shares as set
forth in this Section 1.05(g). On the date that is the fifth Business Day (the
"DETERMINATION DATE") prior to the expected Closing Date first scheduled in
accordance with Section 1.03, Voicestream shall reasonably determine, in
consultation with DT, based on information available as of such date, whether a
Cash Adjustment should be made, and if so, shall estimate the Adjusted Aggregate
Cash Amount. Such estimated Adjusted Aggregate Cash Amount may, in Voicestream's
reasonable discretion, after consultation with DT, be conservatively estimated
so as to facilitate the delivery of the tax opinion referred to in Section
6.02(d) on the previously scheduled Closing Date based on such estimated
Adjusted Aggregate Cash Amount.

     If a Cash Adjustment is made after the Determination Date, the Effective
Time and the Closing Date shall be postponed by the minimum number of days, if
any (but not to exceed five (5) Business Days with

                                       A-4
<PAGE>   319

respect to any single postponement), that Voicestream reasonably determines, in
consultation with DT, is necessary for such adjustments to be properly made, and
the Adjusted Aggregate Cash Amount may, in Voicestream's reasonable discretion,
after consultation with DT, be conservatively estimated so as to facilitate the
delivery of the tax opinion referred to in Section 6.02(d) on the postponed
Closing Date based on such Adjusted Aggregate Cash Amount. The Adjusted
Aggregate Cash Amount divided by the Aggregate Cash Amount shall be referred to
herein as the "ADJUSTMENT FACTOR".

     (ii) In the event the Aggregate Cash Amount is adjusted pursuant to the
first sentence of Section 1.05(g)(i), then the amount of cash that would
otherwise be payable in respect of a Voicestream Common Share subject to a Cash
Election, a Stock Election or a Mixed Election (respectively, a "CASH ELECTION
BASE AMOUNT", "STOCK ELECTION BASE AMOUNT" or "MIXED ELECTION BASE AMOUNT", and
each, a "BASE AMOUNT"), shall be reduced by the difference (respectively, the
"CASH ELECTION DIFFERENCE", the "STOCK ELECTION DIFFERENCE" and the "MIXED
ELECTION DIFFERENCE", and each, an "ELECTION DIFFERENCE") between such Base
Amount and the product of such Base Amount and the Adjustment Factor. In
substitution for the reduction of the cash portion of the Merger Consideration
resulting from the Election Difference,

          (1) each share with respect to which a Cash Election shall have been
     made shall also receive a number of DT Ordinary Shares equal to the Cash
     Election Difference divided by the DT Share Price;

          (2) each share with respect to which a Stock Election shall have been
     made shall also receive a number of DT Ordinary Shares equal to the Stock
     Election Difference divided by the DT Share Price;

          (3) each share with respect to which a Mixed Election shall have been
     made shall also receive a number of DT Ordinary Shares equal to the Mixed
     Election Difference divided by the DT Share Price.

     (iii) The term "DT SHARE PRICE" means the average (rounded to the nearest
1/10,000) of the DT Daily Prices for the seven (7) Frankfurt Stock Exchange
("FSE") trading days randomly selected by lot by DT and Voicestream together
from the fifteen consecutive FSE trading days ending on the day prior to the day
on which the relevant Cash Adjustment is made, and the term "DT DAILY PRICE" for
any trading day means the volume weighted average (rounded to the nearest
1/10,000) of the per share trading prices of DT Ordinary Shares on the FSE (in
Euros, as reported by the Frankfurt Stock Exchange Xetra trading system (or such
other source as Voicestream and DT shall agree in writing) on such FSE trading
day, converted into U.S. Dollars at a fixed exchange rate of one Euro to 0.9216
of a U.S. Dollar; provided, that if, prior to such conversion the DT Share Price
would be less than 33 Euros, then the DT Share Price shall be deemed to be 33
Euros.

     (h) Form of Election.  To be effective, an Election Form must be properly
completed and signed, and must be received by the Escrow Agent, accompanied by
the Certificates as to which the election is being made in compliance with the
requirements for surrender of Voicestream Common Shares contained in Section
1.06(a) below by the Election Deadline. DT shall have the discretion, which it
may delegate in whole or in part to the Escrow Agent, to determine whether
Election Forms have been properly completed, signed, submitted and revoked and
to disregard immaterial defects in Election Forms. The decision of DT (or the
Escrow Agent) in such matters shall be conclusive and binding. DT and the Escrow
Agent shall make reasonable efforts to notify any Person of any defect in an
Election Form submitted to the Escrow Agent. The Escrow Agent shall also make
all computations contemplated by this Section 1.05(h), and, absent manifest
error, all such computations shall be conclusive and binding on the holders of
Voicestream Common Shares. If DT or the Escrow Agent shall determine that any
purported Cash Election, Stock Election or Mixed Election (any of such
elections, an "ELECTION") was not properly made, the Voicestream Common Shares
subject to such improperly made Election shall be treated as No Election Shares.
Each Voicestream Common Share as to which neither a valid Mixed Election, a
valid Cash Election nor a valid Stock Election is made, including, without
limitation, Voicestream Common Shares issued on exercise, conversion or exchange
of outstanding options, warrants, rights or convertible or exchangeable
securities after the Election Deadline (as defined below) ("NO ELECTION
SHARES"), shall be

                                       A-5
<PAGE>   320

deemed to have made a valid Mixed Election. A record holder need not make the
same election with respect to all of the Voicestream Common Shares held of
record by such holder or represented by a single Certificate.

     (i) Election Deadline.  DT and Voicestream shall each use its reasonable
best efforts to cause copies of the Election Forms and the Letter of Transmittal
to be mailed to the record holders of Voicestream Common Shares not less than
forty five (45) days prior to the anticipated Effective Time and to make the
Election Forms available promptly to all Persons who become record holders of
Voicestream Common Shares subsequent to the date of such mailing and no later
than the close of business on the second Business Day prior to the Election
Deadline. An Election Form must be received by the Escrow Agent by 5:00 p.m.,
New York City time, on the date (the "ELECTION DEADLINE") that is the fifth
Business Day prior to the first Closing Date scheduled by the parties in
accordance with Section 1.03. All elections may be revoked until the Election
Deadline in writing by the record holders submitting the Election Forms. DT and
Voicestream shall use reasonable efforts to cause a public announcement of the
actual Election Deadline not fewer than five Business Days prior to the Election
Deadline.

     (j) Form of Stock Consideration.  Any DT Ordinary Shares constituting a
portion of the Merger Consideration shall be delivered to the holders of
Voicestream Common Shares in the form of American depositary shares, each
representing the right to receive one DT Ordinary Share (the "DT DEPOSITARY
SHARES"). The DT Depositary Shares may be evidenced by one or more receipts ("DT
ADRS") issued in accordance with the Deposit Agreement, dated as of November 18,
1996, as amended, among DT, Citibank N.A., as Depositary (the "DEPOSITARY"), and
the holders and beneficial owners from time to time of DT ADRs, as it may be
further amended from time to time (the "DEPOSIT AGREEMENT"). Notwithstanding the
foregoing, each Person who is entitled to receive DT Ordinary Shares as Merger
Consideration shall be entitled, with respect to all or any portion of his
Voicestream Common Shares, to make an unconditional and irrevocable election
(the "ORDINARY SHARE ELECTION") to receive DT Ordinary Shares in lieu of DT
Depositary Shares. The Election Forms and the Letter of Transmittal shall
contain a form of Ordinary Share Election and shall be used by each holder of
Voicestream Common Shares who wishes to make an Ordinary Share Election.

     (k) Each share of Merger Sub Common Stock, issued and outstanding
immediately prior to the Effective Time shall, by virtue of the Merger, and
without any action on the part of the holder thereof, no longer be outstanding,
be cancelled and retired. Immediately following the Effective Time, the
Surviving Corporation shall issue to the Escrow Agent a number of shares of
Common Stock par value $0.000001 per share, of the Surviving Corporation
("SURVIVING CORPORATION COMMON STOCK") equal to the total number of Voicestream
Common Shares outstanding immediately prior to the Merger.

     (l) In consideration of the contribution to DT by the Escrow Agent of
Surviving Corporation Common Stock pursuant to Section 1.04(a) hereof, DT shall
issue, in accordance with Section 1.04(a), and deliver to the Escrow Agent, the
maximum number of DT Ordinary Shares (including DT Ordinary Shares underlying DT
Depositary Shares that are to be delivered as part of the Merger Consideration)
that has become payable pursuant to Section 1.05 for delivery to the Merger
Consideration Recipients entitled thereto and shall pay to the Escrow Agent the
Aggregate Cash Amount (or, if applicable, the Adjusted Aggregate Cash Amount)
that has become payable to the Merger Consideration Recipients pursuant to
Section 1.05.

     (m) If, between the date of this Agreement and the Effective Time, all of
the outstanding DT Ordinary Shares, or more than 80% of the outstanding DT
Ordinary Shares pursuant to an exchange offer for all outstanding shares, shall
have been changed into or exchanged for a different number of shares or kind of
shares of DT or another corporation or entity owning more than 80% of the DT
Ordinary Shares, or the DT Ordinary Shares outstanding shall have changed, by
reason of any reclassification, split-up, stock-split, reverse stock-split,
stock dividend, stock combination, recapitalization or redenomination of share
capital, merger or similar statutory procedure or pursuant to an exchange offer,
or DT changes the number of DT Ordinary Shares represented by a DT Depositary
Share, then the Exchange Ratio and/or the amount or form of any portion of the
Merger Consideration that would otherwise be payable in DT

                                       A-6
<PAGE>   321

Ordinary Shares and the issuer thereof and other definitions and provisions of
this Agreement dependent thereon or on the market price therefor, shall be
appropriately adjusted.

     (n) Preferred Stock.  (1) Not later than the third Business Day preceding
the record date for the Voicestream Stockholders' Meeting, each share of 2 1/2%
Convertible Junior Preferred Stock, par value $0.001 per share, of Voicestream
(the "2 1/2% CONVERTIBLE PREFERRED SHARES") shall be converted, in accordance
with paragraphs (i)(i) and (i)(vii) of Section 1 of the Certificate of
Designation of the 2 1/2% Convertible Preferred Shares and the provisions of the
relevant Stockholders Agreement, into Voicestream Common Shares at the
Conversion Rate (as such term is defined in the 2 1/2% Convertible Preferred
Shares Certificate of Designation) in effect on the Conversion Date (as such
term is defined in the 2 1/2% Convertible Preferred Shares Certificate of
Designation).

     (2) (A) If the Effective Time does not occur prior to May 1, 2001, at any
time on or after May 1, 2001 until the Effective Time, DT may, in its sole
discretion by giving ten (10) Business Days prior written notice to Voicestream,
but only if permissible at such time under the terms of any indebtedness of
Voicestream or any of its Significant Subsidiaries existing on the date hereof
(including its credit agreement), require Voicestream to (or to cause Omnipoint
Corporation to) issue a notice of redemption (the "REDEMPTION") with respect to
all shares of Omnipoint Corporation 7% Cumulative Convertible Preferred Stock,
par value $0.001 per share (the "7% CONVERTIBLE PREFERRED SHARES"), in
accordance with Sections 5.1(b) and 5.3 of the Certificate of Designation of the
7% Convertible Preferred Shares, at the Redemption Price (as such term is
defined in the 7% Convertible Preferred Shares Certificate of Designation) in
effect on the Redemption Date (as such term is defined in the 7% Convertible
Preferred Shares Certificate of Designation), which Redemption Price shall be
equal to the appropriate Redemption Price per share set forth in Section 5.1(b)
of the Certificate of Designation of the 7% Convertible Preferred Shares, plus
in each case all accrued and unpaid dividends on such 7% Convertible Preferred
Shares (other than previously declared dividends payable to the holder of record
on a prior date) through and including the Redemption Date, whether or not
declared, which shall be due and payable only in cash out of funds of
Voicestream or Omnipoint Corporation legally available for the payment of
dividends, as more fully provided in the 7% Convertible Preferred Shares
Certificate of Designation.

     (B) If all the 7% Convertible Preferred Shares have not been redeemed
pursuant to paragraph (A) of this Section 1.05(n)(2) prior to the Effective Time
and upon conversion of any outstanding shares of 7% Convertible Preferred Shares
after the Effective Time, the holders thereof become entitled to DT Ordinary
Shares, such DT Ordinary Shares to which such holder of 7% Convertible Preferred
Shares is entitled will be issued from the 7% Convertible Preferred Shares Trust
described in Annex 1.05(n)(2) (the "7% CONVERTIBLE PREFERRED SHARES TRUST"), and
to the extent holders of 7% Convertible Preferred Shares become entitled to cash
payment after the Effective Time, such cash payment to which such holder of 7%
Convertible Preferred Shares is entitled will be paid by DT.

     (3) Any shares of Convertible Voting Preferred Stock held by DT ("DT
PREFERRED SHARES") and any Voicestream 7% Convertible Preferred Stock
outstanding at the Effective Time shall remain outstanding and shall be
unaffected by the Merger.

     (o) Warrants.  If all the warrants granted pursuant to the Omnipoint
Corporation Remainder Warrant Certificate dated May 6, 1997 (the "WARRANTS")
shall not have been exercised prior to the Effective Time and any holder of such
Warrants becomes entitled to DT Ordinary Shares after the Effective Time, such
DT Ordinary Shares to which such holder of Warrants is entitled will be issued
from the Warrants Trust described in Annex 1.05(o) (the "WARRANTS TRUST"), and
to the extent any holder of Warrants become entitled to cash payment after the
Effective Time, such cash payment to which such holder of Warrants is entitled
will be paid by DT.

     (p) Cook Inlet and Cook Inlet Joint Venture Partners.

          (i) To the extent that prior to the Effective Time any of the Cook
     Inlet Partners receives Voicestream Common Shares in respect of its rights
     to exchange its interest in any of the Cook Inlet Joint Ventures or
     Affiliates of such joint ventures (the "COOK INLET EXCHANGE RIGHTS"), such
     Cook Inlet Partner shall have all the rights with respect to such
     Voicestream Common Shares which a Voicestream stockholder has.

                                       A-7
<PAGE>   322

          (ii) To the extent that any of the Cook Inlet Partners does not
     receive Voicestream Common Shares prior to the Effective Time in respect of
     its Cook Inlet Exchange Rights, each Cook Inlet Partner shall be entitled
     to receive the consideration that such Cook Inlet Partner is entitled to
     receive pursuant to the Cook Inlet Exchange Rights. To the extent that, on
     or after the Effective Time, a Cook Inlet Partner is entitled to DT
     Ordinary Shares, such shares will be delivered from the Cook Inlet Partners
     Trust described in Annex 1.05(p) (the "COOK INLET PARTNERS TRUST"), which
     shall be in form and substance reasonably satisfactory to DT and
     Voicestream and to the extent that such Cook Inlet Partner is entitled to
     cash, such cash shall be paid by DT. The consideration payable to a Cook
     Inlet Partner pursuant to this clause (ii) shall not constitute Merger
     Consideration for the purpose of this Agreement.

          (iii) After the date hereof, Voicestream shall use reasonable efforts
     to obtain the agreement of SSPCS Corporation to enter into an agreement
     relating to its Cook Inlet Exchange Rights in a form substantially similar
     to the agreement relating to such matters entered into by Cook Inlet on the
     date hereof.

          (iv) For purposes of this Section 1.05(p) only, references to "Cook
     Inlet Partner", "Cook Inlet Partners" or "Cook Inlet Joint Ventures" shall
     include any entity or entities designated as such by mutual agreement of DT
     and Voicestream.

     SECTION 1.06.  Surrender and Payment.  (a) Promptly after the Effective
Time, the Surviving Corporation will send, or will cause the Escrow Agent to
send, to each holder of record as of the Effective Time of Voicestream Common
Shares (other than holders of Excluded Voicestream Shares and Dissenting Shares
and holders of Voicestream Common Shares who made a valid Election with respect
to all their shares), a letter of transmittal which shall specify that the
delivery of Certificates shall be effected, and risk of loss and title shall
pass, only upon proper delivery of a Certificate to the Escrow Agent, and
instructions for use in effecting the surrender to the Escrow Agent of
Certificates in exchange for the Merger Consideration (the "LETTER OF
TRANSMITTAL"). The Letter of Transmittal shall contain such other terms and
conditions as DT and Voicestream may reasonably specify.

     (b) Each record holder of any Voicestream Common Shares that have been
converted into a right to receive the consideration set forth in Section 1.05(b)
shall, upon surrender to the Escrow Agent of a Certificate or Certificates,
together with a properly completed Letter of Transmittal covering the
Voicestream Common Shares represented by such Certificate or Certificates,
without further action, be entitled to receive, and the Escrow Agent shall
deliver (and DT shall cause the Escrow Agent to deliver) to each such holder,
subject to Section 1.06(e) below, (i) the number of whole DT Depositary Shares
or DT Ordinary Shares included in the Merger Consideration in respect of such
Voicestream Common Shares, subject to the provisions of Section 1.05, and (ii) a
check in the amount (after giving effect to any required tax withholdings) of
(A) the cash consideration that such holder has the right to receive pursuant to
Section 1.05, plus (B) any cash in lieu of Fractional Interests to be paid
pursuant to Section 1.09, plus (C) any cash dividends or other distributions
that such holder has the right to receive pursuant to Section 1.06(f). Until so
surrendered, each such Certificate shall, after the Effective Time, represent
for all purposes only the right to receive the number of whole DT Depositary
Shares or DT Ordinary Shares, as applicable, to which it is entitled pursuant to
Section 1.05 and the applicable amounts of cash provided in the foregoing clause
(ii) of the preceding sentence.

     (c) If any DT Depositary Shares or DT Ordinary Shares are to be delivered
to a Person (as defined below) other than the registered holder of the
Voicestream Common Shares represented by a Certificate or Certificates
surrendered with respect thereto, it shall be a condition to such issuance that
the Certificate or Certificates so surrendered shall be properly endorsed or
otherwise be in proper form for transfer and that the Person requesting such
delivery shall pay to the Escrow Agent any transfer or other taxes required as a
result of such delivery to a Person other than the registered holder of such
Voicestream Common Shares or establish to the satisfaction of the Escrow Agent
that such tax has been paid or is not payable.

     (d) The stock transfer books of Voicestream shall be closed after the close
of trading on the NASDAQ on the Trading Day immediately prior to the Effective
Time, and thereafter there shall be no

                                       A-8
<PAGE>   323

further registration of transfers of Voicestream Common Shares that were
outstanding prior to the Effective Time. After the Effective Time, Certificates
presented to the Surviving Corporation for transfer shall be canceled and
exchanged for the consideration provided for, and in accordance with the
procedures set forth, in this Article I.

     (e) Any DT Ordinary Shares issued and delivered in respect of Voicestream
Common Shares pursuant to this Article I, any cash entitled to be received
therefor pursuant to Section 1.05, and any cash in lieu of Fractional Interests
to be paid pursuant to Section 1.09, plus any cash dividend or other
distribution that such holder has the right to receive pursuant to Section
1.06(f) that remains unclaimed by any holder of Voicestream Common Shares six
months after the Effective Time, shall be held by the Escrow Agent (or a
successor agent appointed by DT) or shall be delivered to the Depositary upon
the instruction of DT and held by the Depositary, in either case subject to the
instruction of DT, in an account or accounts designated for such purpose. DT
shall not be liable to any holder of Voicestream Common Shares for any
securities delivered or any amount paid by the Depositary, the Escrow Agent or
its nominee, as the case may be, to a public official which it is so required to
pay under applicable abandoned property laws. Any cash remaining unclaimed by
holders of Voicestream Common Shares five years after the Effective Time (or
such earlier date immediately prior to such time as such cash would otherwise
escheat to or become property of any governmental entity or as is otherwise
provided by applicable Legal Requirements (as defined below)) shall, to the
extent permitted by applicable Legal Requirements, become the property of the
Surviving Corporation or DT, as DT may determine.

     (f) No dividends or other distributions nor any voting rights with respect
to securities of DT issuable to the Escrow Agent with respect to Voicestream
Common Shares shall be paid to or exercised by the holder of any unsurrendered
Certificates until such Certificates are surrendered as provided in this
Section. Subject to the effect of applicable Legal Requirements, upon such
surrender, there shall be issued and/or paid to the holder of DT Depositary
Shares or DT Ordinary Shares issued in exchange therefor, without interest and
after giving effect to any required tax withholding, (A) at the time of such
surrender, the dividends or other distributions payable with respect to such DT
Depositary Shares or DT Ordinary Shares with a record date after the Effective
Time and a payment date on or prior to the date of such surrender and not
previously paid and (B) at the appropriate payment date, the dividends or other
distributions payable with respect to such DT Depositary Shares or DT Ordinary
Shares with a record date after the Effective Time but with a payment date
subsequent to such surrender. For purposes of dividends or other distributions
in respect of DT Depositary Shares or DT Ordinary Shares, all DT Depositary
Shares and DT Ordinary Shares to be issued pursuant to the Merger shall be
deemed issued and outstanding as of the Effective Time. Notwithstanding the
foregoing, no dividends or other distributions nor any voting rights with
respect to securities of DT issuable to the Escrow Agent for the account of the
Dissenting Stockholders Trustee, the Options Trustee, the Warrants Trustee, the
7% Convertible Preferred Shares Trustee and the Cook Inlet Partners Shares
Trustee shall be paid to or exercised by any such trustees.

     SECTION 1.07.  [Reserved]

     SECTION 1.08.  Treatment of Voicestream Stock Plans.  (a) Subject to the
consummation of the Merger, immediately prior to the Effective Time, each
outstanding option to purchase Voicestream Common Shares (each, a "VOICESTREAM
OPTION") will be converted (and such Voicestream Option will be extinguished)
into a right to acquire (each, a "VOICESTREAM ROLLOVER OPTION") from the Options
Trust described in Annex 1.08(a) (which shall be in form and substance
reasonably satisfactory to DT and Voicestream) on the same terms and conditions
as were applicable under the Voicestream Option (but taking into account any
changes thereto, including any acceleration thereof, provided for in the option
award or in the Voicestream option plans listed on Schedule 1.08(ii) (the
"VOICESTREAM OPTION PLANS") and applicable to such Voicestream Options by reason
of this Agreement or the transactions contemplated hereby) that number of DT
Ordinary Shares (the "VOICESTREAM OPTION AMOUNT") determined by multiplying the
maximum number of Voicestream Common Shares subject to such Voicestream Option
by the Exchange Ratio, rounded if necessary to the nearest whole DT Ordinary
Share at an exercise price per DT Ordinary Share equal to the exercise price per
Voicestream Common Share in effect with respect to such Voicestream Option
immediately prior to the Effective Time divided by the Exchange Ratio. In order
to implement the conversion of the Voicestream Options described above, the
arrangements set forth in
                                       A-9
<PAGE>   324

Annex 1.08(a) will be effected at the Effective Time. In the case of a
Voicestream Option which is intended to be an incentive stock option under
Section 422 of the Code, the adjustment in this Section 1.08 shall be modified
if necessary to permit such Voicestream Option to continue to comply with
Section 422 of the Code. Prior to the Effective Time, Voicestream and DT shall
mutually agree to either terminate Voicestream's Employee Stock Purchase Plan or
to convert the options under such plan to Voicestream Rollover Options under
this Section 1.08(a).

     (b) Subject to the consummation of the Merger, immediately prior to the
Effective Time, each outstanding award of Voicestream restricted shares that
remains subject to restrictions at the Effective Time (the "VOICESTREAM
RESTRICTED SHARES") will be converted (and such Voicestream Restricted Shares
will be extinguished) into a right to receive (each, a "VOICESTREAM ROLLOVER
RESTRICTED SHARE") from the Restricted Shares Trust described in Annex 1.08(b),
on the same terms and conditions and subject to the same vesting provisions as
were applicable to such award under the Voicestream Plans listed on Schedule
1.08(ii) (but taking into account any changes thereto provided for in the
Voicestream Plans listed on Schedule 1.08(ii)) that number of DT Ordinary Shares
(the "RESTRICTED SHARE AMOUNT") determined by multiplying the number of shares
of Voicestream Common Stock subject to the award by the Exchange Ratio, rounded
if necessary, to the nearest whole DT Ordinary Share. In order to implement the
conversion of the Voicestream Restricted Shares described above, the
arrangements set forth in Annex 1.08(b) will be effected at the Effective Time.

     (c) To the extent that any Person would otherwise be entitled to receive a
fraction of a DT Ordinary Share pursuant to this Section 1.08, such fraction
shall be treated in accordance with Section 1.09.

     (d) As soon as practicable after the Effective Time, DT shall cause to be
delivered to the holders of Voicestream Options and Voicestream Restricted
Shares appropriate notices setting forth such holders' rights pursuant to the
respective Voicestream Plans and agreements evidencing the grants of such
Voicestream Options and Voicestream Restricted Shares (including that, in
connection with the Merger and to the extent provided by the terms of the
Voicestream Plans and award agreements thereunder, the Voicestream Options
subject to change of control vesting have become fully vested).

     (e) No later than the Effective Time, DT shall file or cause to be filed
with the SEC a registration statement on an appropriate form or a post-effective
amendment to a previously filed registration statement under the Securities Act
with respect to the DT Ordinary Shares and DT Depositary Shares which are
subject to the Voicestream Rollover Options as provided in Section 1.08(a), and
shall use reasonable best efforts to maintain the current status of the
prospectus associated therewith, as well as to comply with any applicable state
securities or "blue sky" laws for so long as such options remain outstanding.

     SECTION 1.09.  Fractional DT Depositary Shares and Fractional DT Ordinary
Shares.  No fraction of a DT Depositary Share or a DT Ordinary Share will be
issued, but each holder of Voicestream Common Shares otherwise entitled to
receive a fraction of a DT Depositary Share or DT Ordinary Share will be
entitled to receive in accordance with the provisions of this Section 1.09 from
the Escrow Agent a cash payment in lieu of such fraction of a DT Depositary
Share or DT Ordinary Share, as applicable, (each a "FRACTIONAL INTEREST")
representing such holder's proportionate interest in the net proceeds from the
sale by the Escrow Agent on behalf of all such holders of the aggregate of the
fractions of DT Depositary Shares and DT Ordinary Shares which would otherwise
be issued ("EXCESS ADSS" and "EXCESS SHARES", respectively). The sale of the
Excess ADSs and the Excess Shares by the Escrow Agent shall be executed on the
New York Stock Exchange, Inc. (the "NYSE") and the FSE, respectively, through
one or more member firms of the NYSE or the FSE, as the case may be, and shall
be executed in round lots to the extent practicable. Until the net proceeds of
such sale or sales have been distributed to the holders of Voicestream Common
Shares otherwise entitled to receive Fractional Interests, the Escrow Agent will
hold such proceeds in trust for such holders of Voicestream Common Shares (the
"COMMON SHARES TRUST"). DT shall pay all commissions, transfer taxes and other
out-of-pocket transaction costs, including the expenses and compensation, of the
Escrow Agent incurred in connection with such sale of the Excess ADSs and Excess
Shares. The Escrow Agent shall determine the portion of the Common Shares Trust
to which each holder of Voicestream Common Shares shall be entitled, if any, by
multiplying

                                      A-10
<PAGE>   325

the amount of the aggregate net proceeds comprising the Common Shares Trust by a
fraction, the numerator of which is the amount of Fractional Interests to which
such holder of Voicestream Common Shares is entitled and the denominator of
which is the aggregate amount of Fractional Interests to which all holders of
Voicestream Common Shares are entitled. As soon as practicable after the
determination of the amount of cash, if any, to be paid to holders of
Voicestream Common Shares in lieu of any Fractional Interests, the Escrow Agent
shall make available such amounts to such holders of Voicestream Common Shares
without interest.

     SECTION 1.10.  The Surviving Corporation.  (a) The certificate of
incorporation of Voicestream in effect at the Effective Time shall, by virtue of
the Merger, be amended and restated as of the Effective Time to be identical to
the certificate of incorporation of Merger Sub (except that Article I thereof
shall read: "The name of the Corporation is Voicestream Wireless Corporation")
and, as so amended and restated, shall be the certificate of incorporation of
the Surviving Corporation until amended in accordance with applicable law.

     (b) The bylaws of Merger Sub in effect at the Effective Time shall be the
bylaws of the Surviving Corporation until amended in accordance with applicable
law, provided that from and after the Effective Time the bylaws of Merger Sub
shall contain provisions identical to Article VII of the bylaws of Voicestream
as in effect as of the date of this Agreement.

     (c) The directors of Merger Sub and the officers of Voicestream immediately
prior to the Effective Time shall be the directors and officers of the Surviving
Corporation, respectively, and such individuals shall serve in such positions
until their successors shall have been duly elected and shall qualify.

     SECTION 1.11.  Lost, Stolen or Destroyed Certificates.  In the event any
Certificate shall have been lost, stolen or destroyed, upon the holder's
compliance with the replacement requirements established by the Escrow Agent,
including, if necessary, the posting by such Person of a bond in customary
amount as indemnity against any claim that may be made against it with respect
to such Certificate, the Escrow Agent will issue in exchange for such lost,
stolen or destroyed Certificate, the Merger Consideration and any cash payable
in lieu of Fractional Interests and any unpaid dividends or other distributions
deliverable pursuant to Section 1.06(f) in respect of the Voicestream Common
Shares represented by such Certificate pursuant to this Agreement.

     SECTION 1.12.  Dissenting Shares.  Voicestream Common Shares which are
issued and outstanding immediately prior to the Effective Time and which are
held by a holder who has not voted such shares in favor of the Merger, who shall
have delivered a written demand for appraisal of such shares in the manner
provided by Delaware Law and who shall not have effectively withdrawn or lost
such right to appraisal as of the Effective Time ("DISSENTING SHARES"), shall be
entitled to such rights (but only such rights) as are granted by Section 262 of
the Delaware Law. Each holder of Dissenting Shares who becomes entitled to
payment for such Dissenting Shares pursuant to Section 262 of the Delaware Law
shall receive payment therefor from the Surviving Corporation in accordance with
Delaware Law; provided, however, that (i) if any such holder of Dissenting
Shares shall have failed to establish his entitlement to appraisal rights as
provided in Section 262 of the Delaware Law, (ii) if any holder of Dissenting
Shares shall have effectively withdrawn his demand for appraisal of such Shares
or lost his right to appraisal and payment for his Shares under Section 262 of
the Delaware Law or (iii) if neither any holder of Dissenting Shares nor the
Surviving Corporation shall have filed a petition demanding a determination of
the value of all Dissenting Shares within the time provided for the filing of
such petition in Section 262 of the Delaware Law, such holder shall forfeit the
right to appraisal of such Dissenting Shares and the holder of each such
Dissenting Share shall be deemed to have made a Mixed Election pursuant to
Section 1.05(d) and each such Share shall be converted into the right to receive
the Mixed Consideration pursuant to Section 1.05(d). Voicestream shall give DT
prompt notice of any demands received by Voicestream for appraisal of
Voicestream Common Shares and DT shall have the right to conduct all
negotiations and proceedings with respect to such demands. Except with the prior
written consent of DT, Voicestream shall not make any payment with respect to,
or settle or offer to settle, any such demands. To the extent holders of
Dissenting Shares become entitled to DT Ordinary Shares or cash

                                      A-11
<PAGE>   326

after the Effective Time, such DT Ordinary Shares and cash to which such holder
of Dissenting Shares is entitled will be issued from the Dissenting Stockholder
Trust described in Annex 1.12 (the "DISSENTING STOCKHOLDERS TRUST").

                                   ARTICLE 2

                 REPRESENTATIONS AND WARRANTIES OF VOICESTREAM

     Except as disclosed in the Voicestream SEC Reports filed prior to the date

Adverse Effect on Voicestream. Schedule 2.01 sets forth a list of all
Voicestream Significant Subsidiaries and all entities in which Voicestream has

date hereof, of Voicestream and each of its Significant Subsidiaries. Such
Certificates of Incorporation and Bylaws are in full force and effect. Neither
Voicestream, any of its Significant Subsidiaries nor any of the Cook Inlet Joint
Ventures is in violation of any of the provisions of its respective Certificate
of Incorporation or, in any material respect, its Bylaws or similar constituent
documents.

any of its Subsidiaries is subject to any material requirement to provide funds
for or to make any investment (in the form of a loan, capital contribution or
otherwise) to or in any Cook Inlet Joint Venture, any Other Joint Venture or any
other non-Affiliated entity.

default) under, or give to others any rights of termination or cancellation or
repurchase of, or result in the creation of a lien or encumbrance on any of the
properties or assets of Voicestream or any of its Subsidiaries or any Cook Inlet
Joint Venture pursuant to, or result in the loss of any material benefit or
right, or result in an acceleration of any rights or amounts due resulting from
a change of control or otherwise, or require the consent of any other party to,
any contract, instrument, Permit, license or franchise to which Voicestream or
any of its Significant Subsidiaries or any Cook Inlet Joint Venture is a party
or by which Voicestream, any of such Subsidiaries or any Cook Inlet Joint
Venture or any of their respective property is bound or affected, except, in the
case of clauses (ii), (iii) and (iv) above, for conflicts, violations, breaches,

<PAGE>   329

required pursuant to the rules of any applicable stock exchanges (collectively,
the "VOICESTREAM REQUIRED APPROVALS"), neither Voicestream nor any of its
Subsidiaries nor any Cook Inlet Joint Venture is required to submit any notice,

connection with the execution, delivery or performance of this Agreement or the
DT Financing Agreements. Except as set forth in the immediately preceding
sentence, no waiver, consent, approval or authorization of any Governmental or
Regulatory Authority is required to be obtained by Voicestream or any of its
Subsidiaries or any Cook Inlet Joint Venture in connection with its execution,
delivery or performance of this Agreement or the DT Financing Agreements.

     SECTION 2.06.  SEC Filings; Financial Statements.  (a) Each of Voicestream

Voicestream SEC Reports (i) were prepared substantially in accordance with the
requirements of the Securities Act or the Exchange Act, as the case may be, and
the rules and regulations promulgated under each of such respective acts, and
(ii) did not at the time they were filed contain any untrue statement of a

notes thereto) and subject in the case of interim financial statements to normal
year-end adjustments.

     SECTION 2.07.  Absence of Certain Changes or Events.  Except as permitted
by this Agreement or consented to by DT hereunder, (a) since December 31, 1999,

whole, have not incurred since December 31, 1999 any material liabilities or
obligations except (i) liabilities or obligations (1) which are accrued or
reserved against in the Voicestream Financial Statements included in

course of business and consistent with past practices, (ii) liabilities or
obligations which have been discharged or paid in full prior to the date hereof
in the ordinary course of business, (iii) liabilities and obligations which are
of a nature not required to be reflected in the consolidated financial
statements of Voicestream and its Subsidiaries prepared in accordance with GAAP
and (iv) liabilities and obligations arising after December 31, 1999 which,
individually and in the aggregate, would not reasonably be expected to have a
Material Adverse Effect on Voicestream.

     SECTION 2.08.  Litigation.  As of the date hereof, there are no claims,
actions, suits, proceedings or investigations pending or, to Voicestream's
Knowledge, threatened against Voicestream, any of its Subsidiaries or any Cook
Inlet Joint Venture, or any properties or rights of Voicestream, any of its
Subsidiaries or any Cook Inlet Joint Venture, before any Governmental or
Regulatory Authority that would reasonably be expected to result in an adverse
judgment or determination against Voicestream, any of its Subsidiaries or any
Cook Inlet Joint Venture, except for those that are not, individually or in the
aggregate, reasonably likely to have a Material Adverse Effect on Voicestream or
prevent Voicestream from consummating the transactions contemplated by this
Agreement.

of any Governmental or Regulatory Authority (including, without limitation, any
stock exchange or other self-regulatory body) ("LEGAL REQUIREMENTS"), or in

Authority (including, without limitation, any stock exchange or other
self-regulatory body) with respect to Voicestream, its Subsidiaries or any Cook
Inlet Joint Venture in relation to any alleged violation of law or regulation is
pending or, to Voicestream's Knowledge, threatened, nor has any Governmental or
Regulatory Authority (including, without limitation, any stock exchange or other
self-regulatory body) indicated in writing an intention to conduct the same,
except for such investigations which would not reasonably be expected to have,
individually or in the aggregate, a Material Adverse Effect on Voicestream. None
of the representations and warranties made in this Section 2.09 are being made
with respect to Environmental Laws (as defined below).

filed with the Commercial Register, contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or

statement of material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein, in light of the

     SECTION 2.11.  Employee Matters; ERISA.  Except as set forth on Schedule
2.11:

          (a) Schedule 2.11 contains a true and complete list of all material
     employee benefit plans sponsored or maintained by Voicestream or its
     Subsidiaries and covering present or former employees or directors of
     Voicestream and of each of its Subsidiaries or their beneficiaries, or
     providing benefits to such persons in respect of services provided to any
     such entity, or with respect to which Voicestream or any of its
     Subsidiaries has, or has had, an obligation to contribute or any other
     liability, including, but not limited to, any employee benefit plans within
     the meaning of Section 3(3)

                                      A-16
<PAGE>   331

     of the Employee Retirement Income Security Act of 1974, as amended
     ("ERISA"), any deferred compensation, bonus, stock option, restricted
     stock, incentive, profit sharing, retirement, savings, medical, health,
     life insurance, disability, sick leave, cafeteria or flexible spending,
     vacation, unemployment compensation, severance or change in control
     agreements, arrangements, programs, policies or plans and any other benefit
     arrangements or payroll practice (collectively, the "VOICESTREAM BENEFIT
     PLANS"), whether funded or unfunded, insured or uninsured, written or
     unwritten, true and complete copies of which have been provided to DT.

          (b) Except as would not reasonably be expected to result in a Material
     Adverse Effect on Voicestream, all contributions and other payments
     required to be made by Voicestream or any of its Subsidiaries to or under
     any Voicestream Benefit Plan (or to any person pursuant to the terms
     thereof) have been made or the amount of such payment or contribution
     obligation has been reflected in the Voicestream Financial Statements.

          (c) Each of the Voicestream Benefit Plans intended to be "qualified"
     within the meaning of Section 401(a) of the Code has received a favorable
     determination letter from the Internal Revenue Service (the "IRS") or is a
     prototype plan which has received a favorable opinion letter, and, to
     Voicestream's Knowledge, no circumstances exist that could reasonably be
     expected by Voicestream to adversely affect such qualification, except as
     would not reasonably be expected to have a Material Adverse Effect on
     Voicestream. Except as would not reasonably be expected to have a Material
     Adverse Effect on Voicestream, Voicestream is in compliance in all respects
     with, and each of the Voicestream Benefit Plans complies in form with, and
     is and has been operated in all respects in compliance with, all applicable
     Legal Requirements, including, without limitation, ERISA and the Code. No
     assets of Voicestream or any of its Subsidiaries are subject to liens
     arising under ERISA or the Code on account of any Voicestream Benefit Plan,
     neither Voicestream nor any of its Subsidiaries has been required to
     provide any security under Sections 401(a)(29) or 412(f) of the Code, or
     under Section 307 of ERISA, and, to Voicestream's Knowledge, no event has
     occurred that could give rise to any such lien or a requirement to provide
     such security.

          (d) Except as would not reasonably be expected to have a Material
     Adverse Effect on Voicestream, to Voicestream's Knowledge, there does not
     now exist any condition or set of circumstances, that could subject
     Voicestream or any of its Subsidiaries to any material liability arising
     under any indemnity agreement to which Voicestream or any of its
     Subsidiaries is a party, excluding liability for benefit claims and funding
     obligations payable in the ordinary course. No Voicestream Benefit Plan
     subject to Title IV of ERISA has terminated, nor has a "reportable event"
     (within the meaning of Section 4043 of ERISA) occurred with respect to any
     such plan (other than such events with respect to which the reporting
     requirement has been waived by regulation).

          (e) None of the Voicestream Benefit Plans that are "welfare plans"
     within the meaning of Section 3(1) of ERISA provide for any post-employment
     or retiree benefits other than continuation coverage required to be
     provided under Section 4980B of the Code, Part 6 of Title I of ERISA, or
     applicable state law.

          (f) Voicestream has made available to DT a true and correct copy of
     each current or last, in the case where there is no current, expired
     collective bargaining agreement to which Voicestream or any of its
     Subsidiaries is a party or under which Voicestream or any of its
     Subsidiaries has obligations and copies of the following documents with
     respect to each Voicestream Benefit Plan, where applicable, (i) the plan
     documents governing such plan and the most recent summary plan description
     furnished to employees, (ii) the most recent annual reports filed with the
     IRS, (Form 5500-series), including all schedules and attachments thereto,
     (iii) each related trust agreement or other funding arrangement (including
     all amendments to each such agreement), (iv) the most recent determination
     of the IRS with respect to the qualified status of such Voicestream Benefit
     Plan, and any currently-pending application for such a letter, and (v) the
     most recent actuarial report or valuation.

          (g) The consummation or announcement of any transaction contemplated
     by this Agreement will not (either alone or upon the occurrence of any
     additional or further acts or events) result in any

                                      A-17
<PAGE>   332

     (a) payment (whether of severance pay or otherwise) becoming due from
     Voicestream or any of its Subsidiaries to any officer, employee, former
     employee or director thereof or to the trustee under any "rabbi trust" or
     similar arrangement, (b) obligation on the part of Voicestream or DT to pay
     any excise tax or any similar tax imposed on any employee or former
     employee of Voicestream or its subsidiaries under Section 4999 of the Code
     or any other similar taxes except as provided in Schedule 4.01(e), (c)
     benefit under any Voicestream Benefit Plan being established or becoming
     accelerated, vested or payable or (d) "reportable event" (as defined in
     Section 4043 of ERISA) with respect to a Voicestream Benefit Plan subject
     to Title IV of ERISA.

          (h) The consummation or announcement of any transaction contemplated
     by this Agreement will not (either alone or upon the occurrence of any
     additional or further acts or events) result in the disqualification of any
     of the Voicestream Benefit Plans intended to be qualified under, result in
     a prohibited transaction or breach of fiduciary duty under, or otherwise
     violate, ERISA or the Code in a manner that would give rise to material
     liability.

          (i) Except as would not reasonably be expected to have a Material
     Adverse Effect on Voicestream, neither Voicestream nor any of its
     Subsidiaries nor any of their directors, officers, employees or agents, nor
     any "party in interest" or "disqualified person", as such terms are defined
     in Section 3 of ERISA and Section 4975 of the Code, with respect to any
     Voicestream Benefit Plan, has engaged in or been a party to any "prohibited
     transaction", as such term is defined in Section 4975 of the Code or
     Section 406 of ERISA, which is not otherwise exempt, which could result in
     the imposition of either a penalty assessed pursuant to Section 502(i) of
     ERISA or a tax imposed by Section 4975 of the Code upon Voicestream or its
     Subsidiaries, or which could constitute a breach of fiduciary duty which
     could result in liability on the part of Voicestream or any of its
     Subsidiaries.

          (j) No Voicestream Benefit Plan has incurred any "accumulated funding
     deficiency" (as defined in Section 412 of the Code or Part 3 of Title I of
     ERISA), whether or not waived. Neither Voicestream nor any of its
     Subsidiaries has incurred, and none of such entities reasonably expects to
     incur, any material liability to the PBGC with respect to any Voicestream
     Benefit Plan. Neither Voicestream nor any of its Subsidiaries is a party
     to, contributes to, or is required to contribute to, and neither has
     incurred or reasonably expects to incur, any withdrawal liability with
     respect to, any "multiemployer plan" (as defined in Section 3(37) of
     ERISA). No Voicestream Benefit Plan is a "multiple employer plan", within
     the meaning of the Code or ERISA.

          (k) No employee is entitled to any "reload" options under any of the
     Voicestream Benefit Plans.

     SECTION 2.12.  Labor Matters.  As of the date hereof, neither Voicestream
nor any of its Subsidiaries is party to any collective bargaining agreements. As
of the date hereof, there are no labor unions or other organizations
representing or to Voicestream's Knowledge purporting to represent or making
significant or sustained efforts to represent, a significant number of employees
of Voicestream or its Subsidiaries. There is no pending, or, to the knowledge of
Voicestream, threatened labor dispute, strike, work stoppage or other concerted
labor activity against Voicestream or its Subsidiaries which would be reasonably
likely to have a Material Adverse Effect on Voicestream. During the three (3)
year period preceding the date hereof, to the Knowledge of Voicestream, there
have been no significant or sustained efforts to organize activities conducted
by any labor organization or work council or the like with respect to any
employees of Voicestream or its Subsidiaries. Except for any violations, charges
or complaints that would not, individually or in the aggregate, be reasonably
likely to have a Material Adverse Effect on Voicestream, neither Voicestream nor
any of its Subsidiaries has committed any unfair labor practices or violated in
any material respect any applicable employment laws, regulations, ordinances,
rules, orders or decrees in connection with the operation of the respective
businesses of Voicestream and its Subsidiaries and there is no pending or, to
the knowledge of Voicestream, threatened charge, complaint, investigation or
proceeding against Voicestream or its Subsidiaries by or before the National
Labor Relations Board, the Department of Labor, the Equal Employment Opportunity
Commission, the Occupational Health and Safety Administration or any comparable
state or municipal agency by or on behalf of any employee or

                                      A-18
<PAGE>   333

class of employees or by or before any governmental agency relating to a
purported violation of any applicable employment laws, regulations, ordinances,
rules, orders or decrees.

     SECTION 2.13.  Environmental Matters.  Except for such matters that,
individually or in the aggregate, are not reasonably likely to have a Material
Adverse Effect on Voicestream, or would not otherwise require disclosure
pursuant to the Securities Act or Exchange Act, (i) each of Voicestream, its
Subsidiaries and the Cook Inlet Joint Ventures has complied and is in compliance
with all applicable Environmental Laws (as defined below); (ii) the properties
currently owned or operated by it, any of its Subsidiaries or any Cook Inlet
Joint Venture (including soils, groundwater, surface water, buildings or other

disposed, released or otherwise deposited on, under, at or from the properties
formerly owned or operated by it, any of its Subsidiaries or any Cook Inlet

Subsidiaries or any Cook Inlet Joint Venture; (iv) to Voicestream's Knowledge,
neither it nor any of its Subsidiaries nor any Cook Inlet Joint Venture is
subject to liability for any Hazardous Substance disposal or contamination on
any third party property; (v) neither it nor any of its Subsidiaries nor any
Cook Inlet Joint Venture has received any notice, demand, threat, letter, claim
or request for information alleging that it or any of its Subsidiaries may be in
violation of or liable under any Environmental Law (including any claims
relating to electromagnetic fields or microwave transmissions); and (vi) to
Voicestream's Knowledge, neither it nor any of its Subsidiaries nor any Cook
Inlet Joint Venture is subject to any orders, decrees, injunctions or other
arrangements (other than those of general applicability not specifically related
to Voicestream) with any Governmental or Regulatory Authority or is subject to
any indemnity or other agreement with any third party relating to liability
under any Environmental Law or relating to Hazardous Substances (except for such
agreements entered into by Voicestream in the ordinary course of business).

     "ENVIRONMENTAL LAW" means any federal, state, local, foreign or other law
(including common law), statutes, ordinances or codes relating to: (a) the
protection, investigation or restoration of the environment or natural
resources, (b) the handling, use, presence, disposal, release or threatened
release of any Hazardous Substance, or (c) noise, odor, wetlands, pollution,

antitakeover laws and regulations of the State of Delaware or the State of
Washington (collectively, "VOICESTREAM TAKEOVER LAWS") are applicable to the
Merger or the other transactions contemplated by this Agreement, the
Stockholders' Agreement and the DT Financing Agreements.

based upon arrangements made by or on behalf of Voicestream or any of its
Subsidiaries.

     SECTION 2.17.  Tax Matters.  Except as set forth on Schedule 2.17 and
except to the extent that the failure of the following representations to be
true whether considered individually or in the aggregate would not have a
Material Adverse Effect on Voicestream:

          (a) All Tax Returns required to be filed by Voicestream or its
     Subsidiaries on or prior to the Effective Time have been or will be timely
     filed with the appropriate Governmental or Regulatory Authorities and are
     or will be correct in all respects, and all Taxes due by Voicestream or its

     timely paid;

          (b) There are no liens (except for statutory liens for current Taxes

     Voicestream or any of its Subsidiaries resulting from any unpaid Taxes;

          (c) No audit or other proceeding with respect to Taxes due from

     any of its Subsidiaries, is pending, threatened in writing, or being
     conducted by any Governmental or Regulatory Authority;

          (d) Except for complete and accurate copies of tax sharing agreements
     and amendments thereto made available to DT prior to the execution of this
     Agreement and listed in Schedule 2.17, no agreements relating to the
     allocation or sharing of Taxes exist between Voicestream and/or any one of
     its Subsidiaries, on the one hand, and a third party, on the other hand.

          (e) No extension of the statute of limitations on the assessment of
     any Taxes has been granted by Voicestream or any of its Subsidiaries and is
     currently in effect; and

          (f) Neither Voicestream nor any of its Subsidiaries has taken any
     action or knows of any fact that is reasonably likely to (i) prevent or
     impede the Merger from qualifying as a reorganization within the meaning of
     Section 368(a) of the Code or (ii) cause the stockholders of Voicestream,
     other than any such stockholder that would be a "five-percent transferee

     SECTION 2.18.  Intellectual Property.  Voicestream, its Subsidiaries and

individually or in the aggregate material to the conduct of the businesses of
Voicestream, its Subsidiaries and the Cook Inlet Joint Ventures taken as a whole
("VOICESTREAM INTELLECTUAL PROPERTY") except where the failure to have such
right, title and interest or have the right to use such Intellectual Property
would not reasonably be expected to have a Material Adverse Effect on

have not defaulted (except defaults that have been waived) in any material
respect under any license to use Voicestream Intellectual Property, and (ii) are
not as of the date hereof the subject of any proceeding or litigation for

Voicestream nor to Voicestream's Knowledge any of its Subsidiaries, beneficially

each case, shares of capital stock of DT.

     SECTION 2.20.  Certain Contracts.  All material contracts required to be

the first sentence of this Section 2.20, together with the contracts and
agreements required to be set forth on Schedules 2.20 (i) through 2.20 (iv), are

Contracts are valid and in full force and effect on the date hereof except to
the extent they have previously expired in accordance with their terms or, to
the extent such invalidity or failure to be in full force and effect would not
have a Material Adverse Effect on Voicestream, and, to Voicestream's Knowledge,
neither Voicestream nor any of its Subsidiaries nor any Cook Inlet Joint Venture
has violated any provision of, or committed or failed to perform any act which
with or without notice, lapse of time or both would constitute a default under
the provisions of, any Voicestream Contract, except for defaults which
individually and in the aggregate would not reasonably be expected to result in
a Material Adverse Effect on Voicestream.

     SECTION 2.21.  (a) Licenses.  Voicestream, each of its Subsidiaries and
each Cook Inlet Joint Venture are the authorized legal holders or otherwise have
rights to all Permits and licenses and operating rights necessary for the
operation of their businesses as presently operated (collectively, the "SECTION
2.21 LICENSES") and all Section 2.21 Licenses are in full force and effect,
except for such failures to hold or to have such rights or to be in full force
and effect as would not reasonably be expected to have a Material Adverse Effect
on Voicestream. Voicestream and its Subsidiaries and the Cook Inlet Joint
Ventures are each in compliance in all respects with the Communications Act of
1934, as amended, and the rules, regulations and policies of the FCC and all
applicable Governmental or Regulatory Authorities, except for such failure to
comply which would not have a Material Adverse Effect on Voicestream. As of the
date hereof, there is not pending and, to Voicestream's Knowledge, there is not
threatened, any action by or before the FCC or any Governmental or Regulatory
Authority to revoke, suspend, cancel, rescind or modify any of the Section 2.21
Licenses, except for such action or actions which individually and in the
aggregate would not reasonably be expected to have a Material Adverse Effect on
Voicestream. Schedule 2.21 sets forth a complete list of all material Section
2.21 Licenses except for such Section 2.21 Licenses, sold, pledged, disposed of
or encumbered in accordance with Section 4.01(b).

     (b) None of the Section 2.21 Licenses issued by the FCC are held directly
by Voicestream but instead are held through one or more Subsidiaries of
Voicestream or one or more Cook Inlet Joint Ventures.

and is duly qualified to do business, and is in good standing, in each
jurisdiction where the character of its properties owned, operated or leased or
the nature of its activities makes such qualification necessary, except for such

reasonably be expected to have a Material Adverse Effect on DT.

     SECTION 3.02.  Certificate of Incorporation and Bylaws.  DT is an
Aktiengesellschaft organized and existing under the laws of the Federal Republic
of Germany. DT has heretofore furnished, or otherwise made available, to
Voicestream a complete and correct copy of the Memorandum and Articles of

DT free and clear of any liens, security interest, pledges, agreements, claims,

the aggregate, have a Material Adverse Effect on DT. Except as set forth on
Schedule 3.03 or, with respect to Merger Sub, as otherwise contemplated by this
Agreement, there are no existing subscriptions, options, warrants, calls,
commitments, agreements, conversion rights or other rights of any character
(contingent or otherwise) to purchase or

                                      A-22
<PAGE>   337

otherwise acquire from DT or any of DT's Significant Subsidiaries or Merger Sub
at any time, or upon the happening of any stated event, any shares of the
capital stock or other voting or non-voting securities of any DT Subsidiary or
Merger Sub, whether or not presently issued or outstanding (except for rights of
first refusal to purchase interests in Subsidiaries which are not wholly-owned
by DT), and there are no outstanding obligations of DT or any of DT's
Significant Subsidiaries or Merger Sub to repurchase, redeem or otherwise
acquire any shares of capital stock or other voting or non-voting securities of
any of DT's Subsidiaries, other than such as would not, individually or in the
aggregate, have a Material Adverse Effect on DT. The Merger Sub Common Stock
constitutes all of the outstanding capital stock of Merger Sub, and, except as
provided in the last sentence of Section 1.01(b), DT owns 100 percent of the
outstanding capital stock of Merger Sub.

     SECTION 3.04.  Authority Relative to this Agreement.  (a) DT has the
necessary corporate power and authority to enter into this Agreement, the
Stockholders Agreement and the DT Financing Agreements and to carry out its
obligations hereunder and thereunder. The execution and delivery of this
Agreement, the Stockholders Agreement and the DT Financing Agreements by DT and

Section 205(2) of the German Act and except for the application to be filed with
the Commercial Register). This Agreement and the Stockholders Agreement have
been duly executed and delivered by DT and, assuming the due authorization,
execution and delivery thereof by the other Parties, constitutes a legal, valid
and binding obligation of DT, enforceable against it in accordance with their

or other laws relating to or affecting the rights and remedies of creditors
generally and to general principles of equity (regardless of whether considered
in a proceeding in equity or at law).

     (b) Merger Sub has the necessary corporate power and authority to enter
into this Agreement and to carry out its obligations hereunder. The execution
and delivery of this Agreement and the consummation by Merger Sub of the
transactions contemplated hereby have been duly authorized by all necessary
corporate action on the part of Merger Sub and its stockholder. This Agreement

authorization, execution and delivery thereof by the other Parties hereto,
constitutes the legal, valid and binding obligation of Merger Sub, enforceable
against it in accordance with its terms, subject to applicable bankruptcy,
insolvency, reorganization, moratorium or other laws relating to or affecting
the rights and remedies of creditors generally and to general principles of
equity (regardless of whether considered in a proceeding in equity or at law).

     SECTION 3.05.  No Conflict; Required Filings and Consents.  (a) Except as
set forth on Schedule 3.05 or as described in subsection (b) below, the
execution and delivery of this Agreement, the Stockholders Agreement and the DT
Financing Agreements by DT, or, as applicable, by Merger Sub, do not, and the
performance of this Agreement, the Stockholders Agreement and the DT Financing
Agreements by DT, or, as applicable, by Merger Sub, will not, (i) violate or
conflict with the Memorandum and Articles of Association (SATZUNG) or the
Management Board (VORSTAND) Rules of Procedure (GESCHAFTSORDNUNG) of DT, (ii)
conflict with or violate any law, regulation, court order, judgment or decree
applicable to DT, any of its Significant Subsidiaries or Merger Sub or by which
any of their respective property is bound or affected, (iii) violate or conflict
with the Memorandum and Articles of Association (SATZUNG) or the Management
Board (VORSTAND) Rules of Procedure (GESCHAFTSORDNUNG) of any Subsidiaries of DT

any breach of or constitute a default (or an event which with notice or lapse of
time or both would become a default) under, or give to others any rights of
termination or cancellation of, or result in the creation of a lien or
encumbrance on any of the properties or assets of DT or any of its Significant
Subsidiaries or Merger Sub pursuant to, or result in the loss of any material
benefit or right, including the benefit of any standstill agreement, or result
in an acceleration of any rights or amounts due resulting from a change of
control or otherwise, or require the consent of any other party to, any
contract,

                                      A-23
<PAGE>   338

instrument, Permit, license or franchise to which DT or any of its Significant
Subsidiaries or Merger Sub is a party or by which DT or any of such Subsidiaries
or Merger Sub, or any of their respective property is bound or affected, except,
in the case of clauses (ii), (iii) and (iv) above, for conflicts, violations,
breaches, defaults, rights, results or consents which, individually or in the
aggregate, would not have a Material Adverse Effect on DT.

     (b) Except for applicable requirements, if any, of state, local, or foreign
regulatory laws and commissions, the FCC, the Exchange Act, the premerger
notification requirements of the HSR Act, Council Regulation (EEC) No. 4064/89,
if required, filing of a notice pursuant to Section 721 of Exon-Florio, filing
and recordation of appropriate merger or other documents as required by Delaware
Law and any filings required pursuant to any state securities or "blue sky" laws
or the rules of any applicable stock exchanges (the "DT REQUIRED APPROVALS" and
together with the Voicestream Required Approvals, the "REQUIRED REGULATORY
APPROVALS"), neither DT nor any of its Subsidiaries nor Merger Sub is required
to submit any notice, report or other filing with any Governmental or Regulatory
Authority in connection with the execution, delivery or performance of this
Agreement, the Stockholders Agreement and the DT Financing Agreements, as
applicable. Except as set forth in the immediately preceding sentence, no
waiver, consent, approval or authorization of any Governmental or Regulatory
Authority is required to be obtained by DT or any of its Subsidiaries in
connection with its execution, delivery or performance of this Agreement, the
Stockholders Agreement and the DT Financing Agreements.

     SECTION 3.06.  SEC Filings; Financial Statements.  (a) DT has filed all
forms, reports and documents required to be filed with the SEC since January 1,
1999, and has heretofore made available to Voicestream, in the form filed with
the SEC, together with any amendments and exhibits thereto, (i) its Annual
Report on Form 20-F for the fiscal year ended December 31, 1999, and (ii) all
other reports or registration statements filed by DT with the SEC since January
1, 1999 (collectively, the "DT SEC REPORTS"). The DT SEC Reports (i) were
prepared substantially in accordance with the requirements of the Securities Act
or the Exchange Act, as the case may be, and the rules and regulations
promulgated under each of such respective acts, and (ii) did not at the time
they were filed contain any untrue statement of a material fact or omit to state
a material fact required to be stated therein or necessary in order to make the
statements therein, in the light of the circumstances under which they were
made, not misleading.

     (b) The financial statements (the "DT FINANCIAL STATEMENTS"), including all
related notes and schedules, contained in the DT SEC Reports (or incorporated by
reference therein) fairly present the consolidated financial position of DT and
its Subsidiaries as at the respective dates thereof and the consolidated results
of operations and cash flows of DT and its Subsidiaries for the periods
indicated in accordance with generally accepted accounting principles in Germany
(with a reconciliation to GAAP in accordance with SEC rules) applied on a
consistent basis throughout the periods involved (except for changes as
disclosed in the notes thereto) and subject in the case of interim financial
statements to normal year-end adjustments.

     SECTION 3.07.  Absence of Certain Changes or Events.  Except as permitted
by this Agreement or consented to by Voicestream hereunder, (a) since December
31, 1999, there has not been any Material Adverse Effect on DT, and (b) DT and
its Subsidiaries, taken as a whole, have not incurred since December 31, 1999
any material liabilities or obligations except (i) liabilities or obligations
(1) which are accrued or reserved against in the DT Financial Statements or
reflected in the notes thereto or (2) which were incurred after December 31,
1999 in the ordinary course of business and consistent with past practices, (ii)
liabilities or obligations which have been discharged or paid in full prior to
the date hereof in the ordinary course of business, and (iii) liabilities and
obligations which are of a nature not required to be reflected in the
consolidated financial statements of DT and its Subsidiaries prepared in
accordance with GAAP.

     SECTION 3.08.  Litigation.  As of the date hereof, there are no claims,
actions, suits, proceedings or investigations pending or, to DT's Knowledge,
threatened against DT or any of its Subsidiaries, or any properties or rights of
DT or any of its Subsidiaries, before any Governmental or Regulatory Authority
that

                                      A-24
<PAGE>   339

would reasonably be expected to result in an adverse judgment or determination
against DT or any of its Subsidiaries, except for those that are not,
individually or in the aggregate, reasonably likely to have a Material Adverse
Effect on DT or prevent DT from consummating the transactions contemplated by
this Agreement except as set forth on Schedule 3.08 hereof.

     SECTION 3.09.  No Violation of Law.  The business of DT and its
Subsidiaries is not being conducted in violation of any Legal Requirements or in
violation of any Permits, except for possible violations none of which,
individually or in the aggregate, would reasonably be expected to have a
Material Adverse Effect on DT. Except as disclosed in DT SEC Reports filed prior
to the date hereof and as set forth on Schedule 3.09 hereto, as of the date
hereof, no investigation, review or proceeding by any Governmental or Regulatory
Authority (including, without limitation, any stock exchange or other self-
regulatory body) with respect to DT or its Subsidiaries in relation to any
alleged violation of law or regulation is pending or, to DT's Knowledge,
threatened, nor has any Governmental or Regulatory Authority (including, without
limitation, any stock exchange or other self-regulatory body) indicated in
writing an intention to conduct the same, except for such investigations which,
if they resulted in adverse findings, would not reasonably be expected to have,
individually or in the aggregate, a Material Adverse Effect on DT. None of the
representations and warranties made in this Section 3.09 are being made with
respect to Environmental Laws.

     SECTION 3.10.  Information Provided by DT.  None of the information
supplied or to be supplied by or on behalf of DT for inclusion or incorporation
by reference in the Registration Statement will, at the time the Registration
Statement becomes effective under the Securities Act, contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading. None of the
information supplied or to be supplied by or on behalf of DT for inclusion or
incorporation by reference in the Voicestream Proxy Statement will, at the date
mailed to stockholders of Voicestream and at the times of the Voicestream
Stockholders' Meeting, contain any untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary in order
to make the statements therein, in light of the circumstances under which they
are made, not misleading. The Registration Statement (except for information
relating solely to Voicestream) will comply as to form in all material respects
with the provisions of the Securities Act and the rules and regulations
promulgated thereunder. None of the information supplied or to be supplied by or
on behalf of DT for inclusion or incorporation by reference in the German
Listing Prospectus will, at the time the German Listing Prospectus is published,
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances under which they were made, not misleading. None
of the information supplied or to be supplied by or on behalf of DT for
inclusion or incorporation by reference in the auditor's report to be prepared
pursuant to Section 183(3) of the German Act will, at the time the report is
filed with the Commercial Register, contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary to make the statement therein, in light of the circumstances under
which they were made, not misleading.

     SECTION 3.11. Environmental Matters.  Except for such matters that,
individually or in the aggregate, are not reasonably likely to have a Material
Adverse Effect on DT, or would not otherwise require disclosure pursuant to the
Securities Act, or are listed on Schedule 3.11 hereto, (i) each of DT and its
Subsidiaries has complied and is in compliance with all applicable Environmental
Laws (as defined below); (ii) the properties currently owned or operated by it
or any of its Subsidiaries (including soils, groundwater, surface water,
buildings or other structures) are not contaminated with any Hazardous
Substances (as defined below); (iii) to DT's Knowledge, no Hazardous Substances
were present, disposed, released or otherwise deposited on, under, at or from
the properties formerly owned or operated by it or any of its Subsidiaries
during the period of ownership or operation by it or any of its Subsidiaries;
(iv) to DT's Knowledge, neither it nor any of its Subsidiaries is subject to
liability for any Hazardous Substance disposal or contamination on any third
party property; (v) neither it nor any of its Subsidiaries has received any
notice, demand, threat, letter, claim or request for information alleging that
it or any of its Subsidiaries may be in violation of or liable under any
Environmental Law (including any claims relating

                                      A-25
<PAGE>   340

to electromagnetic fields or microwave transmissions); and (vi) to DT's
Knowledge, neither it nor any of its Subsidiaries is subject to any orders,
decrees, injunctions or other arrangements (other than those of general
applicability not specifically related to DT) with any Governmental or
Regulatory Authority or is subject to any indemnity or other agreement with any
third party relating to liability under any Environmental Law or relating to
Hazardous Substances, except for such agreements entered into by DT in the
ordinary course of business.

     SECTION 3.12.  Board Action; Vote Required.  (a) The Management Board
(VORSTAND) and the Supervisory Board (AUFSICHTSRAT) of DT have determined that
the transactions contemplated by this Agreement, the Stockholders Agreement and
the DT Financing Agreements are advisable and in the best interests of DT and
its shareholders.

     (b) No vote of holders of any class or series of DT capital stock,
including, without limitation, holders of DT Ordinary Shares or DT Depositary
Shares, is required for the approval or entering into of this Agreement or the
DT Financing Agreements or the consummation of the transactions contemplated
hereby and thereby, including the Merger.

     SECTION 3.13.  Brokers.  Except for Donaldson, Lufkin & Jenrette and
Dresdner Kleinwort Benson, no broker, finder or investment banker is entitled to
any brokerage, finder's or investment banking fee in connection with the
transactions contemplated by this Agreement based upon arrangements made by or
on behalf of DT or any of its Subsidiaries.

     SECTION 3.14.  Tax Matters.  Except as set forth on Schedule 3.15 attached
hereto and except to the extent that the failure of the following
representations to be true, whether considered individually or in the aggregate,
would not have a Material Adverse Effect on DT;

          (a) All Tax Returns required to be filed by DT or its Subsidiaries on
     or prior to the Effective Time have been or will be timely filed with the
     appropriate Governmental or Regulatory Authorities and are or will be
     correct in all respects, and all Taxes due by DT or its Subsidiaries on or
     prior to the Effective Time have been, or will be, timely paid;

          (b) The assets of DT do not consist wholly or principally of immovable
     property situated within Germany within the meaning of Article 13(2)(b) of
     the Income Tax Treaty between Germany and the United States.

          (c) There are no liens (except for statutory liens for current Taxes
     not yet due and payable) against any domestic or foreign assets of DT or
     any of its Subsidiaries resulting from any unpaid Taxes;

          (d) No audit or other proceeding with respect to Taxes due from DT or
     any of its Subsidiaries, or any Tax Return of DT or any of its
     Subsidiaries, is pending, threatened in writing, or being conducted by any
     Governmental or Regulatory Authority;

          (e) No extension of the statute of limitations on the assessment of
     any Taxes has been granted by DT or any of its Subsidiaries and is
     currently in effect; and

          (f) Neither DT nor any of its Subsidiaries has taken any action or
     knows of any fact that is reasonably likely to (i) prevent or impede the
     Merger from qualifying as a reorganization within the meaning of Section
     368(a) of the Code, or (ii) cause the stockholders of Voicestream, other
     than any such stockholder that would be a "five-percent transferee
     shareholder" of DT (within the meaning of U.S. Treasury Regulations Section
     1.367(a)-3(c)(5)) following the Merger, to recognize gain pursuant to
     Section 367(a) of the Code.

          (g) DT is not aware of any German withholding taxes that would be
     applicable to any Merger Consideration to be received in the Merger by
     Voicestream stockholders other than in their capacity as employees of
     Voicestream prior to the Effective Time. Except to the extent required
     under the Code, or any provision of state, local or non-U.S. (other than
     German) tax law, and in the case of withholding or deduction pursuant to
     German tax law, except to the extent required solely as a result

                                      A-26
<PAGE>   341

     of a change in law, including, without limitation, an administrative action
     by a German taxing authority or change, amendment to, or clarification of
     an official position or an official interpretation, occurring after the
     date of this Agreement, neither the Escrow Agent nor DT will deduct or
     withhold any amount on account of Taxes (other than stock transfer, stamp
     taxes, or any other similar Taxes) from the consideration otherwise payable
     pursuant to this Agreement. To the extent that amounts are so withheld by
     the Escrow Agent or DT, as the case may be, such withholdings shall be
     treated for all purposes of this Agreement as having been paid to the
     Shareholders in respect of which such deduction and withholding was made by
     the Escrow Agent or DT, as the case may be.

     SECTION 3.15.  Ownership of Securities.  Except pursuant to the
Stockholders Agreements, the DT Financing Agreements or as set forth on Schedule
3.16, as of the date hereof, neither DT nor, to DT's Knowledge, any of its
Subsidiaries, beneficially owns, directly or indirectly, or is party to any
agreement, arrangement or understanding for the purpose of acquiring, holding,
voting or disposing of, in each case, shares of capital stock of Voicestream
(other than shares held by DT Benefit Plans). Except as set forth on Schedule
3.16 hereto, DT owns no shares of Voicestream Common Stock which would
constitute Disqualified Shares.

     SECTION 3.16.  Certain Contracts.  All material contracts required to be
filed by DT pursuant to Item 19(b) of Form 20-F and Instruction B.2 thereto,
have been filed as exhibits to, or incorporated by reference in, a DT SEC Report
filed after December 31, 1999.

     SECTION 3.17.  Licenses.  DT and each of its Subsidiaries are the
authorized legal holders or otherwise have rights to all material Permits and
licenses and operating rights necessary for the operation of their business as
presently operated, except for such failures as would not reasonably be expected
to have a Material Adverse Effect on DT (collectively, the "DT LICENSES"). As of
the date hereof there is not pending and, to DT's Knowledge, there is not
threatened, any action by or before any Governmental or Regulatory Authority to
revoke, suspend, cancel, rescind or modify in any material respect any of the DT
Licenses which action would reasonably be expected to have a Material Adverse
Effect on DT.

                                   ARTICLE 4

                     CONDUCT OF BUSINESS PENDING THE MERGER

     SECTION 4.01.  Conduct of Business in the Ordinary Course.  Voicestream
covenants and agrees with DT that, between the date hereof and the Effective
Time, except as described on Schedule 4.01 or as otherwise expressly
contemplated hereby, the business of Voicestream and its Subsidiaries shall be
conducted only in, and such entities shall not take any action except in, the
ordinary course of business; and Voicestream for itself and on behalf of its
Subsidiaries agrees with DT to use its commercially reasonable efforts to
preserve substantially intact their business organizations, to keep available
the services of those of their present officers, employees and consultants who
are integral to the operation of their businesses as presently conducted and to
preserve their present relationships with significant customers and suppliers
and with other persons with whom they have significant business relations;
provided, however, that no action by Voicestream or its Subsidiaries with
respect to matters specifically addressed by any other provision of this Section
4.01 or Section 5.15 shall be deemed a breach of this sentence unless such
action would constitute a breach of such other provision. Except as set forth on
Schedule 4.01 or as otherwise expressly contemplated by this Agreement,
Voicestream agrees with DT, on behalf of itself and its Subsidiaries, that they
will not, between the date hereof and the Effective Time directly or indirectly,

     shares of capital stock of, or any other ownership interest in, Voicestream
     or any of its Subsidiaries, except for (A) the issuance of Voicestream

<PAGE>   342

     to Voicestream Common Shares to employees or directors, provided such
     grants shall not exceed 1,500,000 Voicestream Common Shares in the
     aggregate and, provided further, that the consummation of the transactions
     contemplated by this Agreement will not constitute a change in control with
     respect to any such newly granted options, (C) issuances of equity
     securities in respect of options, warrants, convertible securities or other
     rights of any kind to acquire equity securities of any Person that is the

     amend the Certificate of Incorporation or Bylaws (or other comparable
     organizational document) or any certificate of designation of Voicestream,
     or adopt, amend or propose to amend any stockholder rights plan or related
     rights agreement; (iii) split, combine or reclassify any outstanding shares
     of Voicestream Common Shares, or declare, set aside or pay any dividend or
     distribution payable in cash, stock, property or otherwise with respect to
     shares of Voicestream Common Shares; or (iv) redeem, purchase or otherwise
     acquire or offer to redeem, purchase or otherwise acquire any shares of its

     accordance with Article IX of Voicestream's certificate of incorporation
     and (B) in open market transactions, consistent with past practice and in

     restrictions, under Voicestream's employee benefit plans, programs and
     arrangements;

          (b) (i) except in connection with Permitted Swaps or Acquisitions
     pursuant to Section 5.15, acquire (by merger, consolidation, or acquisition

     organization or division thereof or make or increase any investment in
     another entity (other than an entity which is a wholly-owned Subsidiary of
     Voicestream as of the date hereof and other than incorporation of a
     wholly-owned Subsidiary) other than investments permitted by Schedule
     4.01(b); (ii) except in connection with Permitted Swaps or as approved by

     Voicestream may enter into derivative contracts as part of their ordinary
     course investment strategy;

          (e) take any action with respect to the grant of any severance or

     (excluding any stock options granted pursuant to Section 4.01(a)) or
     agreement (except in the ordinary course of business and in amounts and in
     a manner consistent with past practice and subject to the other provisions
     of this Section 4.01);

          (g) file any amended Tax Returns or settle any Tax audits or other tax
     proceedings of Voicestream if the result of such amendment or settlement
     would result in an increase of Voicestream tax liability in excess of
     $15,000,000 or change in any respect (i) its method of tax accounting or
     tax practice or (ii) its accounting policies, methods or procedures, except

     Adverse Effect on Voicestream;

     restricted stock, or other equity based rights (other than stock options
     granted pursuant to Section 4.01(a)); (ii) materially modify any actuarial
     cost method, assumption or practice used in determining benefit
     obligations, annual expense and funding for any Voicestream Benefit Plan,
     except to the extent required by GAAP; (iii) materially modify the
     investment philosophy of the benefit plan trusts or maintain an asset
     allocation which is not consistent with such philosophy, subject to any
     ERISA fiduciary obligation; (iv) subject to any ERISA fiduciary obligation,
     enter into any outsourcing agreement, or any other material contract

<PAGE>   344

     increase the compensation payable to any officer or director (other than
     for normal compensation increases in the ordinary course of business
     consistent with past practice);

          (l) agree to enter into any merger, reorganization, share exchange,
     business combination or similar transaction pursuant to which the
     stockholders of Voicestream will receive any consideration (whether payable
     in cash, securities, property or other consideration) in exchange for their
     Voicestream Common Shares;

          (m) authorize or enter into (i) any material joint venture (other than
     Permitted Swaps and other than joint ventures complying with the
     "designated entity" rules which are required for the completion of any
     Acquisition permitted pursuant to Section 5.15) or (ii) any agreement
     (other than in the ordinary course consistent with its past practice in
     respect of the Cook Inlet Joint Ventures and that does not apply to the
     business of Voicestream or its Subsidiaries outside the United States) that
     has a non-competition provision or similar operational restriction
     applicable to, or could be reasonably anticipated to be applicable to, the
     business of Voicestream or any of its Subsidiaries and that is reasonably
     expected to be materially adverse to DT or the mobile telecommunication
     business of DT after the Effective Time; or

          (n) authorize or enter into any contract, agreement, commitment or
     arrangement with respect to any of the matters prohibited by this Section

          (o) Notwithstanding anything in this Agreement to the contrary, during
     the period of time beginning on the later of the Election Deadline and the
     fifth Business Day prior to the Effective Time and extending until and
     including the Effective Time, Voicestream shall not take or omit to take
     any action that could increase the number of Voicestream Common Shares
     outstanding on a fully diluted basis.

     SECTION 4.02.  Conduct of Business by DT.  Except as set forth on Schedule
4.02 hereto or as otherwise expressly contemplated by this Agreement, DT agrees
on behalf of itself and its Subsidiaries that they will not, between the date
hereof and the Effective Time, directly or indirectly, do any of the following
without the prior written consent of Voicestream:

          (a) (i) except as may be necessary or required for the purpose of
     using or increasing any or all of DT's authorized capital (GENEHMIGTES
     KAPITAL) or necessary for the conduct of its business, amend or propose to
     amend the Memorandum and Articles of Association (SATZUNG) or Management
     Board (VORSTAND) Rules of Procedure (GESCHAFTSORDNUNG) (or other comparable
     organizational document) of DT in any manner that would be adverse to
     Voicestream or its stockholders; (ii) declare, set aside or pay any
     dividend or distribution payable in cash, stock, property or otherwise with
     respect to shares of DT capital stock (other than regular annual cash
     dividends in a manner consistent with past practice); (iii) repurchase,
     redeem or otherwise acquire any shares of its capital stock or any
     securities convertible, exchangeable or exercisable for or into shares of
     its capital stock, except for repurchases, redemptions or acquisitions not
     exceeding 10% of the total number of DT Ordinary Shares outstanding as of
     the date hereof in the aggregate; or (iv) effect any reclassification,
     recapitalization or restructuring or other similar transaction (other than
     as permitted in clause (ii) of this Section 4.02(a)) that results in the
     direct or indirect receipt by holders of DT Ordinary Shares of any assets,
     property or cash in respect of such DT Ordinary Shares.

          (b) take any action that would be reasonably likely to (i) prevent or
     impede the Merger from qualifying as a reorganization within the meaning of
     Section 368(a) of the Code; or (ii) cause the stockholders of Voicestream
     to recognize gain pursuant to Section 367(a) of the Code; or

          (c) take any action that would reasonably be likely to (i) materially
     adversely affect the ability of the Parties to obtain any Required
     Regulatory Approval or to consummate the transactions contemplated hereby,
     or (ii) materially delay the ability of any of the Parties to obtain any
     Required Regulatory Approval or to consummate the transactions contemplated
     hereby, provided, however, that this Section 4.02(c) shall not preclude any
     acquisitions by DT or any of its Subsidiaries so long as

                                      A-30
<PAGE>   345

     such acquisitions, individually or in the aggregate, are not reasonably
     likely to prevent the consummation of the Merger.

     SECTION 4.03.  No Solicitation.  (a) From and after the date hereof,
Voicestream shall not, nor shall it permit any of its Subsidiaries to, nor shall
they authorize or instruct any of their respective officers, directors or
employees to, and shall use their reasonable efforts to cause any investment
banker, financial advisor, attorney, accountants or other representatives
retained by them or any of their respective Subsidiaries not to, directly or
indirectly through another person, (i) solicit, initiate or knowingly encourage
(including by way of furnishing information), or knowingly take any other action
designed to facilitate, any Alternative Transaction (as defined below), or (ii)
participate in any substantive discussions or negotiations regarding any
Alternative Transaction; provided, however, that if, at any time prior to the
time the Voicestream Stockholders' Approval is obtained, the Board of Directors
of Voicestream receives an unsolicited bona fide proposal and determines in good
faith that providing information to the Third Party (as defined below), making
such proposal or participating in negotiations or discussions with the Third
Party could be reasonably expected to result in a Voicestream Superior Proposal
(as defined below) and if Voicestream is not in breach of its obligations under
this Section 4.03, Voicestream may, subject to giving DT 48 hours advance
written notice of its intention to do so, (x) furnish information with respect
to Voicestream pursuant to a confidentiality agreement from the Third Party
substantially similar to the Mutual Nondisclosure Agreement between Voicestream
and DT dated as of June 21, 2000 (the "CONFIDENTIALITY AGREEMENT"), and (y)
engage in discussions and negotiations with the persons that made such proposal.
Voicestream shall promptly notify DT orally and in writing of any request for
information or of any proposal in connection with an Alternative Transaction,
the material terms and conditions of such request or proposal and the identity
of the person making such request or proposal. Voicestream will keep DT informed
of the status (including amendments) of such request or proposal on a current
basis. Voicestream shall immediately cease and terminate any existing
solicitations, discussions or negotiations with any persons conducted heretofore
by it or its representatives with respect to the foregoing.

     (b) Nothing contained in this Section 4.03 or in Section 5.02 shall
prohibit Voicestream (x) from taking and disclosing to its stockholders a
position contemplated by Rule 14d-9 or Rule 14e-2(a) promulgated under the
Exchange Act, or (y) from making any disclosure to its stockholders if, in the
good faith judgment of the Board of Directors of Voicestream, after receipt of
advice from outside counsel, failure to disclose would result in a reasonable
likelihood that the Board of Directors of Voicestream would breach its duties to
Voicestream's stockholders under applicable law.

     (c) For purposes of this Agreement, "ALTERNATIVE TRANSACTION" means a
proposal or intended proposal, regarding any of (i) a transaction or series of
transactions pursuant to which any Person (or group of Persons) other than a
Party and its Subsidiaries (a "THIRD PARTY") acquires or would acquire, directly
or indirectly, beneficial ownership (as defined in Rule 13d-3 under the Exchange
Act) of more than twenty percent (20%) of the outstanding shares of Voicestream,
(ii) any acquisition or proposed acquisition of, or business combination with
Voicestream or any of its Significant Subsidiaries, as applicable, by a merger
or other business combination (including any so-called "merger-of-equals" and
whether or not Voicestream or any of its Significant Subsidiaries, as the case
may be, is the entity surviving any such merger or business combination), other
than any transaction that would be permitted pursuant to Section 5.15 hereof, or
(iii) any other transaction pursuant to which any Third Party acquires or would
acquire, directly or indirectly, control of assets (including for this purpose
the outstanding equity securities of Subsidiaries of Voicestream and any entity
surviving the merger or business combination including any of them) of
Voicestream or any of its Subsidiaries, as the case may be, for consideration
equal to twenty percent (20%) or more of the fair market value of all of the
outstanding shares of Voicestream Common Stock on the date of this Agreement.

     SECTION 4.04.  Subsequent Financial Statements.  Voicestream, prior to the
Effective Time, will timely file with the SEC each Annual Report on Form 10-K,
Quarterly Report on Form 10-Q and Current Report on Form 8-K required to be
filed by it under the Exchange Act and the rules and regulations promulgated
thereunder and will promptly deliver to DT copies of each such report filed with
the SEC. DT will timely file with the SEC each Annual Report on Form 20-F and
Report on Form 6-K

                                      A-31
<PAGE>   346

required to be filed by it under the Exchange Act and the rules and regulations
promulgated thereunder and will promptly deliver to Voicestream copies of each
such report filed with the SEC. As of their respective dates, none of such
reports shall contain any untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading. The respective audited financial statements and unaudited interim
financial statements of each of Voicestream and DT, as the case may be, included
in such reports will fairly present the financial position of such Party and its
Subsidiaries as at the dates thereof and the results of their operations and
cash flows for the periods then ended in accordance with GAAP (with a
reconciliation to GAAP in accordance with SEC rules in the case of Voicestream)
or generally accepted accounting principles in Germany (in the case of DT)
applied on a consistent basis and, subject, in the case of unaudited interim
financial statements, to normal year-end adjustments and any other adjustments
described therein.

     SECTION 4.05.  Control of Operations.  Nothing contained in this Agreement
shall give DT, directly or indirectly, the right to control or direct
Voicestream's operations prior to the Effective Time. Prior to the Effective
Time, Voicestream shall exercise, consistent with the terms and conditions of
this Agreement, complete control and supervision over its respective operations.

                                   ARTICLE 5

                             ADDITIONAL AGREEMENTS

     SECTION 5.01.  Voicestream Proxy Statement; the Registration Statement and
the German Listing Prospectus.  Each of DT and Voicestream shall cooperate and
promptly prepare and DT shall file with the SEC as soon as practicable a
Registration Statement on Form F-4 (or any successor form) (the "FORM F-4")
under the Securities Act with respect to the DT Ordinary Shares and the DT
Depositary Shares issuable and deliverable pursuant to this Agreement. A portion
of the Form F-4 shall serve as a prospectus with respect to the DT Ordinary
Shares and the DT Depositary Shares issuable and deliverable pursuant to the
terms of this Agreement and as Voicestream's proxy statement with respect to
Voicestream Stockholders' Meeting (the "VOICESTREAM PROXY STATEMENT"). DT will
cause the Form F-4 to comply as to form in all material respects with the
applicable provisions of the Securities Act and the rules and regulations
thereunder and Voicestream will cause the Voicestream Proxy Statement to comply
as to form in all material respects with the applicable provisions of the
Exchange Act and the rules and regulations thereunder. Voicestream and DT shall
use their reasonable best efforts to have the Voicestream Proxy Statement and
Registration Statement declared effective by the SEC under the Securities Act,
and promptly thereafter shall mail to the holders of record of Voicestream
Common Shares, the Voicestream Proxy Statement; provided, however, that
Voicestream shall not mail or otherwise furnish the Voicestream Proxy Statement
to its stockholders unless and until:

          (i) it has received notice from the SEC that the Registration
     Statement is effective under the Securities Act;

          (ii) Voicestream shall have received a letter of its independent
     accountants, dated a date within two (2) business days prior to the date of
     the first mailing of the Voicestream Proxy Statement, and addressed to
     Voicestream, in form reasonably satisfactory to Voicestream and customary
     in scope for similar "cold comfort" letters delivered by independent public
     accountants in connection with registration statements on Form F-4 with
     respect to the financial statements of DT included in the Voicestream Proxy
     Statement and the Registration Statement;

          (iii) DT shall have received a letter of its independent accountants,
     dated a date within two (2) business days prior to the date of the first
     mailing of the Voicestream Proxy Statement, and addressed to DT, in form
     reasonably satisfactory to DT and customary in scope for similar "cold
     comfort" letters delivered by independent public accountants in connection
     with registration statements on Form F-4 with respect to the financial
     statements of Voicestream included in the Voicestream Proxy Statement and
     the Registration Statement.

                                      A-32
<PAGE>   347

     DT shall use reasonable best efforts to obtain prior to the effective date
of the Form F-4, all necessary state securities law or "Blue Sky" permits or
approvals required to effect the transactions contemplated by this Agreement. DT
will advise Voicestream, promptly after it receives notice, of the time when the
Form F-4 has become effective or any supplement or amendment has been filed, the
issuance of any stop order or the suspension of the qualification of the DT
Depositary Shares or DT Ordinary Shares issuable and deliverable in connection
with the Merger for offering or sale in any jurisdiction.

     (b) DT and Voicestream will cooperate in (i) the preparation of the
Voicestream Proxy Statement and the Registration Statement and in having the
Registration Statement declared effective as soon as practicable and (ii) the
preparation and filing of the German Listing Prospectus with the FSE and the
auditor's report with the Commercial Register.

     SECTION 5.02.  Voicestream Stockholders' Meeting and Consummation of the
Merger.  (a) As promptly as practicable after the Registration Statement is
declared effective under the Securities Act, Voicestream shall duly give notice
of, convene and hold a meeting of its stockholders (the "VOICESTREAM
STOCKHOLDERS' MEETING") in accordance with Delaware Law for the purposes of
obtaining the Voicestream Stockholder Approval and shall, subject to the
provisions of Section 5.02(b) hereof, through its Board of Directors, recommend
to its stockholders the approval and adoption of this Agreement and use its
reasonable best efforts to obtain the Voicestream Stockholder Approval.

     (b) Neither the Board of Directors of Voicestream nor any committee thereof
shall (i) except as expressly permitted by this Section 5.02(b), withdraw,
qualify or modify, or propose publicly to withdraw, qualify or modify, in a
manner adverse to DT, the approval or recommendation of such Board of Directors
or such committee of this Agreement, the Merger and the other transactions
contemplated hereby, (ii) approve or recommend, or propose publicly to approve
or recommend, any Alternative Transaction, or (iii) cause Voicestream to enter
into any letter of intent, agreement in principle, acquisition agreement or
other similar agreement for any Alternative Transaction (each, a "VOICESTREAM
ACQUISITION AGREEMENT"). Notwithstanding the foregoing, in the event that prior
to the time the Voicestream Stockholder Approval is obtained, Voicestream
receives a Superior Proposal (as defined below), the Board of Directors of
Voicestream may (subject to this and the following sentences) (A) inform
Voicestream stockholders that it no longer recommends Voicestream Stockholder
Approval (a "SUBSEQUENT DETERMINATION"), but only at a time that is after the
second Business Day following DT's receipt of written notice advising DT that
the Board of Directors of Voicestream has received a Superior Proposal
specifying the material terms and conditions of such Superior Proposal (and
including a copy or draft copy thereof with all accompanying documentation or
draft documentation, if in writing), identifying the Person making such Superior
Proposal and stating that it intends to make a Subsequent Determination. After
providing such notice, Voicestream shall provide a reasonable opportunity to DT
to make such adjustments in the terms and conditions of this Agreement as would
enable Voicestream to proceed with its recommendation to its stockholders
without a Subsequent Determination; provided, however, that any such adjustment
shall be at the discretion of Voicestream and DT at the time. For purposes of
this Agreement, a "SUPERIOR PROPOSAL" means any proposal (on its most recently
amended or modified terms, if amended or modified) made by a Third Party to
enter into an Alternative Transaction which the Board of Directors of
Voicestream determines in its good faith judgment to be more favorable to
Voicestream's stockholders than the transactions contemplated by this Agreement.
Voicestream shall submit this Agreement to its stockholders at the Voicestream
Stockholders' Meeting even if the Board of Directors of Voicestream shall have
made a Subsequent Determination.

     SECTION 5.03.  Cook Inlet.  Voicestream shall not agree to any modification
of the existing exchange rights agreements relating to the Cook Inlet Joint
Ventures that would (i) prior to the Effective Date, increase the number of
Voicestream Common Shares issuable to the Cook Inlet Joint Ventures upon
exercise of their exchange rights in excess of the maximum number of shares set
forth on Schedule 2.03(f) on and after the Effective Date, increase the number
of DT Ordinary Shares or DT Depositary Shares issuable to the Cook Inlet Joint
Ventures upon exercise of their exchange rights.

<PAGE>   348

     SECTION 5.04.  Notification of Certain Matters.  Each of Voicestream and DT
shall give prompt notice to each other of the following:

          (a) the occurrence or nonoccurrence of any event whose occurrence or
     nonoccurrence would be likely to cause either (i) any representation or
     warranty contained in this Agreement of such Party to be untrue, inaccurate
     or incomplete in any material respect at any time from the date hereof to
     the Effective Time if such failure to be true, accurate or complete would
     cause the condition set forth in Section 6.02(a) or 6.03(a) not to be
     satisfied, in which case the Party required to give prompt notice thereof
     shall promptly update and deliver to the others any Schedules hereto which
     require an update to remain true, accurate and correct or (ii) directly or
     indirectly, any Material Adverse Effect on such Party;

          (b) any material failure of such Party, or any officer, director,
     employee or agent of any thereof, to comply with or satisfy any covenant or
     agreement to be complied with or satisfied by it hereunder (if such failure
     would cause the condition set forth in Section 6.02(b) or 6.03(b) not to be
     satisfied);

          (c) any facts relating to such Party which would make it necessary or
     advisable to amend the Voicestream Proxy Statement or the Registration
     Statement in order to make the statements therein not misleading or to
     comply with applicable law; provided, however, that the delivery of any
     notice pursuant to this Section 5.04 shall not limit or otherwise affect
     the remedies available hereunder to the Parties receiving such notice; and

          (d) Promptly upon receipt by Voicestream from any Voicestream
     stockholder who is a party to the Stockholder Agreements of a proxy card
     sent to the Voicestream stockholders with the Voicestream Proxy Statement
     and in accordance with Section 5 of the Stockholders Agreements, but in no
     event later than the second Business Day following such receipt or, if such
     receipt is on or after the fifth Business Day prior to the Closing, then on
     the date of such receipt, Voicestream shall notify DT orally of its receipt
     and provide DT with copy of such proxy card.

          (e) Voicestream will not settle any claim with respect to Section 1.19
     and 1.20 the Tax Sharing Agreement (the "355 Provisions") or amend, modify
     or terminate the 355 provisions without the prior written consent of DT.
     Voicestream will promptly provide DT with any notice of indemnification
     claim or other notice of communication with respect to or under the Tax
     Sharing Agreement with respect to the 355 Provisions. Voicestream will use
     its reasonable best efforts to permit DT to participate in the negotiation,
     resolution, settlement and contest of any claim or tax refund related to
     any items for which Voicestream has sole indemnification responsibility
     under the Section 355 Provisions.

     SECTION 5.05.  Access to Information.  (a) Each of Voicestream and DT
shall, and shall cause its respective Subsidiaries, and its and their officers,
directors, employees, auditors, counsel and agents to afford the officers,
employees, auditors, counsel and agents of the other Parties reasonable access
during regular business hours to such Party's and its Subsidiaries' officers,
employees, auditors, counsel, agents, properties, offices and other facilities
and to all of their respective books and records, and shall furnish the other
with all financial, operating and other data and information as such other
Parties may reasonably request. Notwithstanding the foregoing, neither
Voicestream nor DT shall be required to provide any information which it
reasonably believes it may not provide to the other Party by reason of any Legal
Requirements or other applicable law, rules or regulations, which constitutes
information protected by attorney/client privilege, or which it or any of its
Subsidiaries is required to keep confidential by reason of contract, agreement
or understanding with third parties.

     (b) Each of Voicestream and DT agrees that all non-public, confidential
information so received from any other Party shall be deemed received pursuant
to the Confidentiality Agreement and shall cause its Subsidiaries and each of
its and their respective officers, directors, employees, financial advisors,
attorneys, accountants, consultants and agents ("PARTY REPRESENTATIVES") to,
comply with the provisions of the Confidentiality Agreement with respect to such
information, and the provisions of the Confidentiality Agreement are hereby
incorporated herein by reference with the same effect as if fully set forth
herein.

<PAGE>   349

     SECTION 5.06.  Public Announcements.  Voicestream and DT shall develop a
joint communications plan and each Party shall, except as otherwise required by
any Legal Requirement, use its reasonable best efforts to ensure that all press
releases and other public statements with respect to the transactions
contemplated hereby shall be consistent with such joint communications plan or,
to the extent inconsistent therewith, shall have received the prior written
approval of the other Parties.

     SECTION 5.07.  Cooperation.  (a) Upon the terms and subject to the
conditions hereof, each of Voicestream and DT agrees, and agrees to cooperate
with each other, (w) to take or cause to be taken all actions and to do or cause
to be done all things necessary, proper or advisable to consummate the
transactions contemplated by this Agreement (including all actions expected to
be taken after the Effective Time in connection with the actions contemplated by
Section 1.04), (x) to obtain in a timely manner all necessary Permits or
waivers, from, approvals or consents of, or declarations, registrations or
filings with, and all expirations of waiting periods imposed by, any
Governmental or Regulatory Authority which are necessary for the consummation of
the transactions contemplated hereby, (y) to promptly (1) prepare and file a
Premerger Notification in accordance with the HSR Act, comply with any requests
for additional information, and obtain termination of the waiting period
thereunder as promptly as practicable, (2) prepare and file all required
notifications, if any, under Council Regulation (EEC) No. 4064/89, and obtain
the approval of the Council of the European Union to the transactions
contemplated by this Agreement, if required, and (3) file a notice pursuant to
Section 721 of Exon-Florio, and (z) to take all actions within its control
necessary to obtain any Required Regulatory Approvals necessary to consummate
the transactions contemplated hereby; provided, however, that nothing in this
sentence of Section 5.07(a) shall require DT or Voicestream to take any action
that would result in a Burdensome Condition;

     (b) Each of Voicestream and DT agrees to cooperate with each other (1) to
respond to inquiries from, and to make presentations to, Governmental or
Regulatory Authorities; and (2) to promptly inform the others of any material
oral or written communication received by such Party from, or given by such
Party to, any Governmental or Regulatory Authority, and of any material
communication received or given in connection with any proceeding by a private
Party, in each case regarding the relevant transactions. Voicestream and DT
agree to consult with each other in advance of any meeting or conference with,
or of making any filing or other written submission to, any such Governmental or
Regulatory Authority, and to the extent permitted by the applicable Governmental
or Regulatory Authority, give the others the opportunity to attend and
participate in such meetings and conferences, or to review and approve any such
filing or other written submission, in each case regarding the relevant
transactions.

     (c) Each of Voicestream and DT shall cooperate with each other to eliminate
or reduce to the extent possible any illegality, forfeiture or loss on the part
of DT, Voicestream or their respective Subsidiaries that may result from the
consummation of the transactions contemplated hereby.

     (d) Each of Voicestream and DT hereby agrees to cooperate with the other
party, and to cause its officers, directors and independent accountants to
cooperate with the other party, to do or cause to be done all things reasonably
requested by the other party (including, without limitation, providing such
information as may reasonably be requested to permit pro forma financial
statements after giving effect to the Merger to be produced) in order to
facilitate any financing, acquisition or capital markets transaction to be
entered into by either Party after the date hereof.

     (e) Voicestream hereby agrees to use reasonable best efforts, in
consultation with DT, to obtain all waivers and consents that may be required
from any parties to any Voicestream Contract, including, without limitation,
from lenders and other financing sources of Voicestream and its Subsidiaries, in
connection with this Agreement, the Stockholders Agreements, the DT Financing
Agreements and the transactions contemplated hereby and thereby.

     (f) Voicestream hereby agrees, from the date hereof until the Closing, to
take any and all actions that are required to be taken prior to the Effective
Time pursuant to any Voicestream Contract or other agreement, including, without
limitation, any debt instruments, including credit agreements and indentures, to
which Voicestream or any of its Significant Subsidiaries or any Cook Inlet Joint
Venture is a party and

to make any offer to purchase any securities required to be made, as a result of
the execution and delivery of this Agreement, the Stockholders Agreements and
the DT Financing Agreements.

     SECTION 5.08.  Indemnification, Directors' and Officers'
Insurance.  (a) For a period of six (6) years after the Effective Time, the
Surviving Corporation (i) shall maintain in effect the current provisions
regarding indemnification of officers and directors contained in the charter and
bylaws of Voicestream and each of its Subsidiaries and any directors, officers
or employees indemnification agreements of Voicestream and its Subsidiaries,
(ii) shall maintain in effect the current policies of directors' and officers'
liability insurance and fiduciary liability insurance maintained by Voicestream
("D&O INSURANCE") (provided that the Surviving Corporation may substitute
therefor policies of at least the same coverage and amounts containing terms and
conditions which are, in the aggregate, no less advantageous to the insured),
with respect to claims arising from facts or events which occurred on or before
the Effective Time, provided, however, if the existing D&O Insurance expires, is
terminated or cancelled, or if the annual premium therefor is increased to an
amount in excess of 250% of the last annual premium paid prior to the date
hereof, in each case during such six year period, the Surviving Corporation will
use its best efforts to obtain D&O Insurance in an amount and scope as great as
can be obtained for the remainder of such period for a premium not in excess (on
an annualized basis) of 250% of the Current Premium and (iii) shall indemnify
the directors and officers of Voicestream to the fullest extent to which
Voicestream is permitted to indemnify such officers and directors under their
respective charters and bylaws and applicable law.

     (b) Without limiting Section 5.08(a), after the Effective Time, each of DT
and the Surviving Corporation shall, to the fullest extent permitted under
applicable law, indemnify and hold harmless, each present and former director,
officer, employee and agent of Voicestream or any of its Subsidiaries (each,
together with such person's heirs, executors or administrators, an "INDEMNIFIED
PARTY" and collectively, the "INDEMNIFIED PARTIES") against any costs or
expenses (including attorneys' fees), judgments, fines, losses, claims, damages,
liabilities and amounts paid in settlement in connection with any actual or
threatened claim, action, suit, proceeding or investigation, whether civil,
criminal, administrative or investigative, arising out of, relating to or in
connection with any action or omission occurring or alleged to occur prior to
the Effective Time (including, without limitation, acts or omissions in
connection with such persons serving as an officer, director or other fiduciary
in any entity if such service was at the request or for the benefit of
Voicestream) or arising out of or pertaining to this Agreement, the Merger and
the other transactions contemplated by this Agreement and the DT Financing
Agreements. In the event of any such actual or threatened claim, action, suit,
proceeding or investigation (whether arising before or after the Effective
Time), (i) DT and the Surviving Corporation, as the case may be, shall pay the
reasonable fees and out of pocket expenses of counsel selected by the
Indemnified Parties, which counsel shall be reasonably satisfactory to DT and
the Surviving Corporation, promptly after statements therefor are received and
shall pay all other reasonable out of pocket expenses in advance of the final
disposition of such action, (ii) DT and the Surviving Corporation will cooperate
and use all reasonable efforts to assist in the vigorous defense of any such
matter, and (iii) to the extent any determination is required to be made with
respect to whether an Indemnified Party's conduct complies with the standards
set forth under Delaware Law and DT's or the Surviving Corporation's respective
articles of incorporation or bylaws, such determination shall be made by
independent legal counsel acceptable to DT or the Surviving Corporation, as the
case may be, and the Indemnified Party; provided, however, that neither DT nor
the Surviving Corporation shall be liable for any settlement effected without
its written consent (which consent shall not be unreasonably withheld). The
Indemnified Parties as a group may not retain more than one law firm to
represent them with respect to each matter unless there is, under applicable
standards of professional conduct, a conflict on any significant issue between
the positions of any two or more Indemnified Parties.

     SECTION 5.09.  Stock Exchange Listings/Establishment of DT Depositary
Shares.  DT will take all steps necessary for the listing and authorization for
listing on the FSE and the NYSE (subject to official notice of issuance) of the
DT Ordinary Shares and the DT Depositary Shares, respectively, to be issued
pursuant to the Merger.

     SECTION 5.10.  No Shelf Registration.  DT shall not be required to amend or
maintain the effectiveness of the Registration Statement for the purpose of
permitting resale of the shares of DT received pursuant hereto by the Persons
who may be deemed to be "affiliates" of Voicestream within the meaning of Rule
145 promulgated under the Securities Act. The DT Ordinary Shares issuable upon
exercise of options pursuant to Section 1.05 hereof shall be registered under
the Securities Act and such registration shall be effective at the time of
issuance.

     SECTION 5.11.  Affiliates.  Voicestream (i) shall deliver to DT not later
than the 30th day after the date of this Agreement a list of all persons who
are, as of the date hereof its Affiliates for purposes of Rule 145 under the
Securities Act, and (ii) shall use its reasonable best efforts to cause each
person who is identified as its "affiliate" on Schedule 5.11 to deliver to DT as
promptly as practicable but in no event later than the Closing Date, a signed
agreement substantially in the form of Exhibit A. Voicestream shall notify DT
from time to time of any other persons who then are such an "affiliate" of
Voicestream and use its reasonable best efforts to cause each additional person
who is identified as such an "affiliate" to execute a signed agreement as set
forth in this Section 5.11.

     SECTION 5.12.  Blue Sky.  DT will use its reasonable best efforts to obtain
prior to the Effective Time all necessary state securities or "blue sky" Permits
and approvals or similar foreign approvals required to permit the distribution
of the DT Depositary Shares and the DT Ordinary Shares to be issued in
accordance with the provisions of this Agreement, and Voicestream will provide
any reasonably requested cooperation in connection therewith.

     SECTION 5.13.  Tax-Free Merger.  Each of the Parties will use its
reasonable best efforts, and each agrees to cooperate with the other Parties and
provide one another with such documentation, information and materials, as may
be reasonably necessary, proper or advisable, to (i) cause the Merger to qualify
as a reorganization within the meaning of Section 368(a) of the Code and (ii)
avoid gain recognition to the Stockholders of Voicestream pursuant to Section
367(a) of the Code.

     SECTION 5.14.  Interim Dividend Policy.  Voicestream shall not, without the
prior written consent of DT, declare, set aside or pay any dividend or
distribution payable in cash, stock, property or otherwise with respect to
shares of Voicestream Common Stock.

     SECTION 5.15.  Permitted Acquisitions.  (a) Voicestream and its
Subsidiaries may only engage in an acquisition transaction taking the form of a
stock acquisition, asset acquisition, merger or similar type or form of
transaction, including, without limitation, any transaction pursuant to which
Voicestream would propose to acquire, directly or indirectly, any additional FCC
licenses, and may only make investments in other Persons (collectively,
"ACQUISITIONS") subject to the provisions of this Section 5.15 and subject to
the provisions of Sections 4.01(h), (i) and (m). Subject to Sections 4.01(h),
(i) and (m), Voicestream and its Subsidiaries may engage in (A) Acquisitions in
accordance with Section 5.15(b), (B) Acquisitions without DT's consent, provided
that the aggregate value of the consideration payable by Voicestream and any of
its Subsidiaries in respect of any Acquisition pursuant to this clause (B) shall
not exceed $500 million (including assumption of debt) and in respect of all
Acquisitions pursuant to this clause (B) shall not exceed in the aggregate $750
million (including assumptions of debt), and, provided further, that, without
consent of the Acquisitions Committee (as hereinafter defined), none of such
Acquisitions include shares of Voicestream or any of its Subsidiaries as
consideration for the transaction, and (C) Acquisitions permitted (or deemed
permitted) by the Acquisitions Committee. The Acquisitions Committee shall
consist of the individuals listed on Schedule 5.15(C). If Voicestream desires to
make or engage in an Acquisition requiring consent of the Acquisitions
Committee, it shall notify (a "PROPOSED ACQUISITION NOTICE") the Acquisitions
Committee in writing (care of the office of the Chairman of the Acquisitions
Committee) of such proposed Acquisition (a "PROPOSED ACQUISITION"). The Proposed
Acquisition Notice shall include or be preceded by a copy of the material
information upon which senior management of Voicestream relied in determining
that Voicestream should pursue the Proposed Acquisition. Unless the Acquisitions
Committee denies permission in writing (in care of the office of Voicestream's
Chief Executive Officer) which is received within five (5) Business Days of
receipt of the Proposed Acquisition Notice, the Proposed Acquisition shall be
deemed to have been consented to and permitted by this

                                      A-37
<PAGE>   352

Section 5.15 and for all purposes under this Agreement (and shall not count
toward the individual or aggregate dollar limitation set forth in clause (B) of
this Section 5.15(a) nor shall any securities issued in connection therewith be
deemed to breach any restriction contained in Section 4.01. DT agrees and
acknowledges that if the Acquisitions Committee denies Voicestream permission to
proceed with any Proposed Acquisition, thereafter any officer, director,
stockholder or Affiliate of Voicestream (other than any of Voicestream's
Subsidiaries), or any group or combination of them, may pursue or engage in such
Proposed Acquisition for his, its or their own account. The Acquisitions
Committee shall also, from time to time, consider the capital structure of
Voicestream.

     (b) In the event that Voicestream determines to participate in any auction
of spectrum or airwave rights or licenses conducted during the period from the
date hereof until the Effective Time or the termination of this Agreement (an
"AUCTION"), then management of Voicestream shall work with the Acquisitions
Committee to develop, not later than the tenth Business Day prior to the date
the short form application related to such Auction is due, a schedule (a "BID
SCHEDULE") of maximum amounts that Voicestream shall be permitted to bid in such
Auction, which shall set forth both a maximum bid per license or market (as
applicable), and an aggregate maximum for the entire Auction. In the event that,
in the course of an Auction, Voicestream desires to bid in excess of the maximum
bid permitted in the Bid Schedule for any market or license, as applicable, or
the maximum aggregate of all bids, Voicestream may do so only with the consent
of any one of the members of the Acquisitions Committee (which consent may be
sought and/or granted by telephone). Unless any of the members of the
Acquisitions Committee denies such request to exceed such maximum bid (a
"PROPOSED BID INCREASE") within 24 hours of the time such request shall have
been made, DT shall be deemed to have consented to such request. DT hereby
agrees and acknowledges that in the event that Voicestream and the Acquisitions
Committee fail to agree upon a Bid Schedule prior to the tenth Business Day
prior to the schedule commencement of any Auction, thereafter any officer,
director, stockholder or Affiliate of Voicestream (other than any of
Voicestream's Subsidiaries), or any group or combination of them, may
participate in such Auction and acquire rights or licenses pursuant thereto for
his, its or their own account.

     SECTION 5.16.  Reasonable Best Efforts.  Each of Voicestream and DT shall
use its reasonable best efforts to obtain the opinions referred to in Section
6.02(d) and the delivery of the executed Representation Letters in the forms set
forth in Exhibits D and E hereto.

     SECTION 5.17.  Certain Matters.  After the Effective Time, DT will take the
actions set forth in Schedule 5.17.

     SECTION 5.18.  Takeover Laws.  Subject to Section 5.02, no Party shall take
any action that would cause the transactions contemplated by this Agreement or
the Stockholders Agreement to be subject to requirements imposed by any Takeover
Laws (including any such laws or regulations applicable to DT under German Legal
Requirements or the Legal Requirements of the FSE) and each of them shall take
all necessary steps within its control to exempt (or ensure the continued
exemption of), or minimize the effect on, the transactions contemplated by this
Agreement and the Stockholders Agreement from, or if necessary challenge the
validity or applicability of, any applicable Takeover Law, as now or hereafter
in effect, including, without limitation, Section 203 of the Delaware Law or any
other Takeover Laws that purport to apply to this Agreement or the Stockholders
Agreement or the transactions contemplated hereby or thereby.

     SECTION 5.19.  Employee Benefits.  (a) From and after the Effective Time,
DT shall cause the Surviving Corporation or its successor to honor all
Voicestream employee benefit plans and compensation arrangements and agreements
in accordance with their terms as in effect immediately before the Effective
Time, subject to any amendment or termination thereof that may be permitted by
such terms. For a period of not less than two years following the Effective
Time, DT shall cause to be provided, to current and former employees of
Voicestream and its Subsidiaries (the "VOICESTREAM EMPLOYEES") compensation and
employee benefits (it being understood that discretionary equity and equity
based awards will remain discretionary) that are, in the aggregate, not less
favorable than those provided to Voicestream Employees immediately before the
Effective Time.

                                      A-38
<PAGE>   353

     (b) For purposes of vesting, eligibility to participate and level of
benefits (but not benefit accrual under pension or similar plans) under the
employee benefit plans of DT and its Affiliates providing benefits to any
Voicestream Employees after the Effective Time (the "NEW PLANS"), each
Voicestream Employee shall be credited with his or her years of service with
Voicestream and its Affiliates before the Effective Time, to the same extent as
such Voicestream Employee was entitled, before the Effective Time, to credit for
such service under any similar Voicestream Employee Benefit Plans in which such
Voicestream Employee participated or was eligible to participate immediately
prior to the Effective Time, provided, that the foregoing shall not apply to the
extent that its application would result in a duplication of benefits or for
newly established plans and programs for which prior service of DT employees is
not taken into account. In addition, and without limiting the generality of the
foregoing: (i) each Voicestream Employee shall be immediately eligible to
participate, without any waiting time, in any and all New Plans to the extent
coverage under such New Plan replaces coverage under a comparable Voicestream
employee benefit plan or compensation arrangement or agreements in which such
Voicestream Employee participated immediately before the consummation of the
Merger (such plans, collectively, the "OLD PLANS"); and (ii) for purposes of
each New Plan providing medical, dental, pharmaceutical and/or vision benefits
to any Voicestream Employee, DT shall cause all pre-existing condition
exclusions and actively-at-work requirements of such New Plan to be waived for
such employee and his or her covered dependents, unless such conditions would
not have been waived under the comparable plans of Voicestream or its
subsidiaries in which such employee participated immediately prior to the
Effective Time and DT shall cause any eligible expenses incurred by such
employee and his or her covered dependents during the portion of the plan year
of the Old Plan ending on the date such employee's participation in the
corresponding New Plan begins to be taken into account under such New Plan for
purposes of satisfying all deductible, coinsurance and maximum out-of-pocket
requirements applicable to such employee and his or her covered dependents for
the applicable plan year as if such amounts had been paid in accordance with
such New Plan.

     (c) DT hereby acknowledges and agrees that the transactions contemplated
hereby will constitute a Change of Control for all purposes under the applicable
Voicestream Employee Benefit Plans listed on Schedule 2.11(g).

     (d) Voicestream and DT shall, during the sixty-day period following the
date hereof, seek to develop a mutually acceptable retention plan for senior
management employees.

     (e) For a period of at least two years following the Effective Time, DT
shall continue and cause to be honored Voicestream's severance policy described
in Schedule 4.01(e) as in effect prior to the Effective Time without any
amendments adverse to Voicestream Employees.

     SECTION 5.20.  Certain Employment Matters.  Prior to the Effective Time, DT
and Voicestream shall take all such steps as may be required to cause the
transactions contemplated by this Agreement, including any dispositions of
Voicestream Common Shares (including derivative securities with respect to the
Voicestream Common Shares) and acquisitions of DT Ordinary Shares (including
derivative securities with respect to DT Ordinary Shares) by each Person who is
or will be subject to the reporting requirements of Section 16(a) of the
Exchange Act with respect to the Voicestream or DT, as the case may be, to be
exempt under Rule 16b-3 promulgated under the Exchange Act.

     prohibiting the consummation of the Merger.

          (c) Required Regulatory Approvals.  Any waiting period applicable to
     the consummation of the Merger under the HSR Act shall have expired or been
     terminated; to the extent required, the Commission of the European Union
     shall have approved the Merger under Regulation (EEC) No. 4064/89 of the
     Council of the European Union, or such approval shall have been deemed to
     have been granted; the review and investigation under Exon-Florio shall
     have been terminated and the President shall have taken no action
     authorized thereunder; and any Required Regulatory Approval of the FCC
     shall have been received and shall be in full force and effect; provided
     that the conditions contained in this paragraph (c) shall not be deemed
     satisfied as to DT or Voicestream, if any such consents or authorizations
     shall contain any conditions (collectively, "BURDENSOME CONDITIONS") that,
     individually or in the aggregate, would reasonably be expected to have a
     Material Adverse Effect on DT or the mobile telecommunications business of
     DT, in each case after giving effect to the transactions contemplated
     hereby and any other acquisition in the mobile telecommunication industry
     which is entered into or consummated by DT or any of its Subsidiaries after
     the date hereof.

     shall have become effective prior to the mailing by Voicestream of the
     Voicestream Proxy Statement to its stockholders, no stop order suspending

     and no proceedings for that purpose shall then be threatened by the SEC or
     shall have been initiated by the SEC and not concluded or withdrawn.

          (e) Stock Exchange Listings.  All steps necessary for the listing of
     the DT Ordinary Shares to be issued pursuant to the Merger on the FSE shall
     have been taken and the DT Depositary Shares to be issued pursuant to the
     Merger shall have been authorized for listing on the NYSE, subject to
     official notice of issuance.

     SECTION 6.02.  Conditions to the Obligations of Voicestream.  The
obligations of Voicestream to consummate the Merger are also subject to the
fulfillment or written waiver by Voicestream, prior to the Effective Time, of
each of the following conditions:

          (a) Representations and Warranties.  The representation and warranty
     set forth in Section 3.07(a) of this Agreement shall have been true and
     correct on the date hereof and on and as of the Closing Date as though made
     on the Closing Date; and the other representations and warranties of DT and
     Merger Sub set forth in this Agreement shall have been true and correct on
     the date hereof (or in the case of matters relating to Merger Sub, as of
     September 28, 2000) and on and as of the Closing Date as though made on the
     Closing Date (except to the extent that any representation or warranty
     expressly speaks as of an earlier date, in which case it shall be true and
     correct as of such date) except (i) for changes permitted under Section
     4.02 or otherwise contemplated by this Agreement, and (ii) for such
     failures to be true and correct which in the aggregate would not reasonably
     be expected to result in a Material Adverse Effect on DT.

                                      A-40
<PAGE>   355

          (b) Agreements and Covenants.  DT shall have performed or complied
     with all agreements and covenants required by this Agreement to be
     performed or complied with by it on or before the Effective Time; provided,
     however, that for purposes of this Section 6.02(b) only, such agreements
     and covenants shall be deemed to have been complied with unless the failure
     or failures of such agreements and covenants to have been complied with,
     individually or in the aggregate, results or would reasonably be expected
     to result in a Material Adverse Effect on DT or on Voicestream
     shareholders.

          (c) Certificates.  Voicestream shall have received a certificate of an
     executive officer of DT (and, to the extent such matters relate to Merger
     Sub, of an executive officer of Merger Sub) to the effect set forth in
     subparagraphs (a) and (b) above.

          (d) Tax Opinion.  Voicestream shall have received an opinion of Jones,
     Day, Reavis & Pogue ("JONES DAY") and/or Wachtell, Lipton, Rosen & Katz
     ("WACHTELL LIPTON") dated as of the Closing Date substantially to the
     effect that, on the basis of the facts, representations and assumptions set
     forth or referred to in such opinion, for U.S. federal income tax purposes,
     the Merger (i) will qualify as a reorganization within the meaning of
     Section 368(a) of the Code and (ii) each transfer of property to DT by a
     stockholder of Voicestream pursuant to the Merger will not be subject to
     Section 367(a)(1) of the Code. In rendering such opinion, Jones Day and/or
     Wachtell Lipton may require and shall be entitled to rely upon customary
     representations of Voicestream and DT, including representations
     substantially in the form of Exhibits D and E, respectively. The opinion
     set forth in clause (ii) may assume that any stockholder who is a
     "five-percent transferee shareholder" with respect to DT within the meaning
     of U.S. Treasury Regulations Section 1.367(a)-3(c)(5)(ii) will file the
     agreement described in U.S. Treasury Regulations Section
     1.3.67(a)-3(c)(1)(iii)(B).

          (a) Representations and Warranties.  The representation and warranty
     of Voicestream set forth in Section 2.07(a) of this Agreement shall have
     been true and correct on the date hereof and on and as of the Closing Date
     as though made on the Closing Date; and the other representations and
     warranties of Voicestream set forth in this Agreement shall have been true
     and correct on the date hereof and on and as of the Closing Date as though
     made on the Closing Date (except to the extent that any representation or
     warranty expressly speaks as of an earlier date, in which case it shall be
     true and correct as of such date) except (i) for changes permitted under
     Section 4.01 hereof or otherwise contemplated by this Agreement, and (ii)
     for such failures to be true and correct which in the aggregate would not
     reasonably be expected to result in a Material Adverse Effect on
     Voicestream.

          (b) Agreements and Covenants.  Voicestream shall have performed or
     complied with all agreements and covenants required by this Agreement to be
     performed or complied with by it on or before the Effective Time; provided,
     however, that for purposes of this Section 6.03(b) only, such agreements
     and covenants shall be deemed to have been complied with unless the failure
     or failures of such agreements and covenants to have been complied with
     individually or in the aggregate, results or would reasonably be expected
     to result in a Material Adverse Effect on DT or the mobile
     telecommunications business of DT, in each case after giving effect to the
     transactions contemplated hereby and any other acquisition in the mobile
     telecommunications industry which is entered into or consummated by DT or
     any of its Subsidiaries after the date hereof.

          (c) Certificates.  DT shall have received a certificate of an
     executive officer of Voicestream to the effect set forth in subparagraphs
     (a) and (b) above.

                       TERMINATION, AMENDMENT AND WAIVER

     SECTION 7.01.  Termination.  This Agreement may be terminated at any time
before the Effective Time, in each case as authorized by the Board of Directors
of Voicestream or the Management Board (VORSTAND) of DT:

          (a) By mutual written consent of each of Voicestream and DT;

          (b) By Voicestream, if the Merger shall not have been consummated on
     or before September 30, 2001 (the "VOICESTREAM TERMINATION DATE") or by DT
     if the Merger shall not have been consummated on or before December 31,
     2001 (the "DT TERMINATION DATE"); provided, however, that the right to
     terminate this Agreement under this Section 7.01(b) shall not be available
     to any Party whose failure to fulfill any obligation under this Agreement
     has been the cause of, or resulted in, the failure of the Effective Time to
     occur on or before the relevant Termination Date;

          (c) By either Voicestream or DT, if (i) any Governmental or Regulatory
     Authority shall have issued an order, decree or ruling or taken any other
     action (which order, decree or ruling Voicestream and DT shall use its
     reasonable best efforts to lift), in each case permanently restraining,
     enjoining or otherwise prohibiting the Merger, or (ii) in connection with
     the grant of any Required Regulatory Approval relating to the Merger, a
     Burdensome Condition shall have been imposed, and in the case of either
     clause (i) or (ii), such order, decree, ruling, Burdensome Condition or
     other action shall have become final and nonappealable;

          (d) By Voicestream, (A) if DT shall have breached or failed to perform
     in any material respect any of its representations, warranties, covenants
     or other agreements contained in this Agreement, which breach or failure to
     perform (1) is incapable of being cured by DT prior to the Voicestream
     Termination Date, or, if capable of being cured, is not cured by DT within
     30 days after written notice thereof shall have been received by DT from

                          AGREEMENT AND PLAN OF MERGER

     This AGREEMENT AND PLAN OF MERGER, dated as of August 26, 2000, as amended
and restated on September 28, 2000, among DEUTSCHE TELEKOM AG, an
AKTIENGESELLSCHAFT organized and existing under the laws of the Federal Republic
of Germany ("DT"), POWERTEL, INC., a Delaware corporation ("POWERTEL") and BEGA
II, INC., a Delaware corporation formed by DT ("MERGER SUB") (each a "PARTY"
and, together, the "PARTIES").

                                  WITNESSETH:

     WHEREAS, VoiceStream Wireless Corporation, a Delaware corporation
("VOICESTREAM"), and DT entered into an Agreement and Plan of Merger dated as of
July 23, 2000 (as amended or modified from time to time, the "VOICESTREAM MERGER
AGREEMENT"), providing for the acquisition of VoiceStream by DT (the
"VOICESTREAM MERGER") and VoiceStream and Powertel are entering into a separate
merger agreement dated as of the date hereof (as amended or modified from time
to time (the "ALTERNATIVE MERGER AGREEMENT"), providing for the acquisition of
Powertel by VoiceStream (the "ALTERNATIVE MERGER") if the VoiceStream Merger
Agreement is terminated and certain other conditions are satisfied or waived;

     WHEREAS, the Management Board (VORSTAND) and the Supervisory Board
(AUFSICHTSRAT) of DT and the Board of Directors of Powertel have determined that
it is fair to and in the best interests of their respective companies and
stockholders to consummate the strategic combination transaction provided for in
this Agreement and the other transactions contemplated hereby in accordance with
the laws of their respective jurisdictions of organization and have authorized
the execution and delivery of this Agreement;

     WHEREAS, the Board of Directors of Merger Sub has determined that it is
advisable and in the best interests of Merger Sub and its stockholder to
consummate the strategic combination transaction provided for in this Agreement
and has authorized the execution and delivery of this Agreement, and DT, as
Merger Sub's sole current stockholder, has approved and adopted this Agreement;

     WHEREAS, simultaneously with the execution and delivery of this Agreement
and the Alternative Merger Agreement, as part of a single overall transaction,
and to induce DT to enter into this Agreement, certain stockholders of Powertel
are each entering into a stockholder agreement (collectively, the "POWERTEL
STOCKHOLDER AGREEMENTS") with DT dated as of the date hereof;

     WHEREAS, for United States federal income tax purposes the parties intend
that the Merger (as defined below) will qualify (i) as a reorganization within
the meaning of Section 368(a) of the Code (as defined below) and (ii) for an
exception to the general rule of Section 367(a)(1) of the Code; and

     WHEREAS, DT and Powertel desire to make certain representations,
warranties, covenants and agreements in connection with the transactions
contemplated by this Agreement.

     NOW, THEREFORE, in consideration of the foregoing and the mutual
representations, warranties, covenants and agreements herein contained, and
intending to be legally bound hereby, DT, Powertel and Merger Sub hereby agree
as follows:

                                   ARTICLE 1

                                   THE MERGER

     SECTION 1.01.  Appointment of Escrow Agent and Formation of Merger
Sub.  (a) Merger Sub is a corporation incorporated pursuant to Delaware Law and
is a constituent company in the Merger. Except as provided in, or contemplated
by, the last sentence of Section 1.01(b), DT owns 100 percent of the outstanding
capital stock of Merger Sub.

                                       B-1
<PAGE>   373

     (b) As soon as practicable after the date hereof, DT shall appoint a United
States bank or trust company or other independent financial institution in the
United States reasonably satisfactory to Powertel to act, inter alia, as escrow
agent and exchange agent for the Merger and the delivery of the Merger
Consideration (as defined below) to former stockholders of Powertel and the
other Merger Consideration Recipients (as defined below) (the "ESCROW AGENT").
DT and Powertel shall enter into an escrow agency agreement with the Escrow
Agent, in substantially the same form as the Escrow Agency Agreement to be
entered into in connection with the VoiceStream Merger Agreement but with such
changes as may be appropriate (the "ESCROW AGENCY AGREEMENT"), which agreement
shall set forth the duties, responsibilities and obligations of the Escrow Agent
consistent with the terms of this Agreement. Solely to accommodate the
transactions described in this Article 1 and subject to the terms and conditions
of the Escrow Agency Agreement, one day prior to the Effective Time DT shall
cause the Escrow Agent to be registered, as DT's fiduciary (for the period prior
to the Effective Time) as the record holder of all of the issued and outstanding
shares of common stock, par value $.000001 per share, of Merger Sub (the "MERGER
SUB COMMON STOCK").

     SECTION 1.02.  The Merger.  (a) Upon the terms and subject to the
conditions of this Agreement and in accordance with Delaware Law, on the Closing
Date (as defined below), Powertel will cause a certificate of merger (the
"CERTIFICATE OF MERGER") to be executed and filed with the Secretary of State of
the State of Delaware and make all other filings or recordings required by
applicable law in connection with the Merger. The Merger shall become effective
at such time as the Certificate of Merger is duly filed with the Secretary of
State of the State of Delaware or at such later time as is specified in the
Certificate of Merger in accordance with Delaware Law (the "EFFECTIVE TIME").

     (b) Upon the terms and subject to the conditions set forth in this
Agreement, at the Effective Time, Merger Sub shall be merged with and into
Powertel in accordance with Delaware Law (the "MERGER"), whereupon the separate
existence of Merger Sub shall cease, Powertel shall be the surviving corporation
in the Merger (the "SURVIVING CORPORATION") and shall continue to be governed by
the laws of the State of Delaware, and the separate corporate existence of
Powertel, with all its rights, privileges, immunities, powers and franchises,
shall continue unaffected by the Merger except as set forth in this Article 1.
The Merger shall have the effects specified in Delaware Law.

     SECTION 1.03.  The Closing.  On the fifth Business Day after the last to be
fulfilled or waived of the conditions set forth in Article 6 hereof (other than
the conditions contained in Sections 6.02(c), 6.02(d), 6.02(e), 6.03(c), 6.03(d)
and 6.03(e) so long as it is reasonably apparent that such conditions and the
condition contained in Section 6.01(b) will be able to be satisfied at the
Closing) shall be fulfilled or waived in accordance with this Agreement, the
closing of the Merger (the "CLOSING") shall be held (but only after all of the
conditions set forth in Article 6 shall have been satisfied or waived prior to
the Effective Time) at such time as DT and Powertel shall agree (the "CLOSING
DATE") at the offices of Cleary, Gottlieb, Steen & Hamilton, New York, New York,
unless this Agreement shall have been terminated and the transactions
contemplated by this Agreement abandoned pursuant to Article 7 or unless another
date, time or place is agreed to in writing by DT and Powertel.

     SECTION 1.04.  The Merger Exchange.

     (a) Upon the terms and subject to the conditions of this Agreement and the
Escrow Agency Agreement, as soon as possible after the Effective Time, (x) on
the Closing Date, the Escrow Agent shall contribute, for the account of the
former stockholders of Powertel, all of the issued and outstanding shares of the
Surviving Corporation Common Stock (as defined below) to DT as a transfer in
kind, and (y) DT shall deliver the Merger Consideration to the Escrow Agent for
the account of (i) the former stockholders of Powertel, (ii) the Options Trustee
(as defined in Annex 1.08(a)), (iii) the Warrants Trustee (as defined in Annex
1.05(h)), (iv) the Eliska Partners Shares Trustee (as defined in Annex 1.05(i))
and (v) the Dissenting Stockholders Trustee (as defined in Annex 1.12 below)
(collectively, the "MERGER CONSIDERATION RECIPIENTS"). DT and the Escrow Agent
shall effect the foregoing in accordance with Sections 183 et seq. and 203 et
seq. of the German Stock Corporation Act (AKTIENGESETZ) (the "GERMAN ACT") by
registering the increase of the DT stated share capital with the commercial
register

                                       B-2
<PAGE>   374

(HANDELSREGISTER) for DT (the "COMMERCIAL REGISTER") as soon as possible after
the Effective Time. In the event that, in connection with the performance of
DT's obligations in this Section 1.04(a), on or prior to the Closing Date the
Management Board of DT passes a resolution to increase the issued capital of DT
in accordance with Article 5(2) of the Articles of Association of DT by such
number of shares as is equal to the number of shares to be delivered as part of
the Merger Consideration, and the Supervisory Board shall have consented
thereto, then (i) the Escrow Agent shall promptly subscribe for such new
ordinary shares of DT ("DT ORDINARY SHARES") to be issued as part of the Merger
Consideration and shall promptly on the Closing Date make the contribution to DT
referred to in the first sentence of this Section 1.04(a) and (ii) the
Management Board and the chairman of the Supervisory Board shall as soon as
possible thereafter file the application for registration of the implementation
of the capital increase with the Commercial Register, with the effect that, on
registration of the capital increase in the Commercial Register, such new DT
Ordinary Shares shall by operation of law be held solely by the Escrow Agent for
delivery to and for the benefit of the Merger Consideration Recipients. At the
Effective Time, the obligations of DT and the Escrow Agent under this Section
1.04(a) shall be unconditional.

     (b) Each share certificate (a "CERTIFICATE") formerly representing any
Powertel Stock (as defined below) (other than Excluded Powertel Shares (as
defined below) and Dissenting Shares (as defined below)) shall thereafter
represent only the right to receive the Merger Consideration as set forth in
Section 1.05(b) and the right, if any, to receive pursuant to Section 1.09 cash
in lieu of fractional DT Depositary Shares (as defined below) or fractional DT
Ordinary Shares, as applicable, and any dividend or distribution pursuant to
Section 1.06(f), in each case, without interest. The DT Ordinary Shares and the
DT Depositary Shares issued as provided in Section 1.05 shall be of the same
class and shall have the same rights as the currently outstanding DT Ordinary
Shares and the currently outstanding DT Depositary Shares, respectively.

     SECTION 1.05.  Conversion and Exchange of Shares.  At the Effective Time:

     (a) Each share of common stock, par value $0.01 per share, of Powertel
("POWERTEL COMMON STOCK") and Powertel Preferred Stock (as defined below) owned
by DT or Powertel immediately prior to the Effective Time (each, an "EXCLUDED
POWERTEL SHARE") shall, by virtue of the Merger, and without any action on the
part of the holder thereof, no longer be outstanding, be cancelled and retired
without payment of any consideration therefor and shall cease to exist.

     (b) By virtue of the Merger and without any action on the part of the
holder thereof (in each of the following cases other than Excluded Powertel
Shares) and subject to the further provisions of this Section 1.05:

          (i) each share of Powertel Common Stock issued and outstanding
     immediately prior to the Effective Time shall be converted into the right
     to receive 2.6353 validly issued, fully paid and nonassessable DT Ordinary
     Shares (the "COMMON STOCK EXCHANGE RATIO");

          (ii) each share of Powertel Series A Preferred Shares (as defined
     below) and Powertel Series B Preferred Shares (as defined below) issued and
     outstanding immediately prior to the Effective Time shall be converted into
     the right to receive 121.9294 validly issued, fully paid and nonassessable
     DT Ordinary Shares (the "SERIES A AND B PREFERRED EXCHANGE RATIO");

          (iii) each share of Powertel Series D Preferred Shares (as defined
     below) issued and outstanding immediately prior to the Effective Time shall
     be converted into the right to receive 93.0106 validly issued, fully paid
     and nonassessable DT Ordinary Shares (the "SERIES D PREFERRED EXCHANGE
     RATIO"); and

          (iv) each share of Powertel Series E Preferred Shares (as defined
     below) and Powertel Series F Preferred Shares (as defined below) issued and
     outstanding prior to the Effective Time shall be converted into the right
     to receive (A) 179.5979 validly issued, fully paid and non-assessable DT
     Ordinary Shares (the "SERIES E AND F PREFERRED EXCHANGE RATIO"), plus (B) a
     number of validly issued, fully paid and nonassessable DT Ordinary Shares
     equal to the product of the number of shares of Powertel Common Stock
     representing accrued or declared but unpaid dividends on such Powertel

                                       B-3
<PAGE>   375

     Series E Preferred Share or Powertel Series F Preferred Share (calculated
     as if the Closing Date were a dividend payment date), as the case may be,
     and the Common Stock Exchange Ratio.

The consideration payable pursuant to this paragraph (b) is referred to herein
as the "MERGER CONSIDERATION."

     (c) Any DT Ordinary Shares constituting a portion of the Merger
Consideration shall be delivered to the holders of Powertel Stock in the form of
American depositary shares, each representing the right to receive one DT
Ordinary Share (the "DT DEPOSITARY SHARES"). The DT Depositary Shares may be
evidenced by one or more receipts ("DT ADRS") issued in accordance with the
Deposit Agreement, dated as of November 18, 1996, as amended, among DT, Citibank
N.A., as Depositary (the "DEPOSITARY"), and the holders and beneficial owners
from time to time of DT ADRs, as it may be further amended from time to time
(the "DEPOSIT AGREEMENT"). Notwithstanding the foregoing, each Person who is
entitled to receive DT Ordinary Shares as Merger Consideration shall be
entitled, with respect to all or any portion of his Powertel Stock, to make an
unconditional and irrevocable election (the "ORDINARY SHARE ELECTION") to
receive DT Ordinary Shares in lieu of DT Depositary Shares. The Letter of
Transmittal (as defined below) shall contain a form of Ordinary Share Election
and shall be used by each holder of Powertel Stock who wishes to make an
Ordinary Share Election.

     (d) Each share of Merger Sub Common Stock issued and outstanding
immediately prior to the Effective Time shall, by virtue of the Merger, and
without any action on the part of the holder thereof, no longer be outstanding,
be cancelled and retired. Immediately following the Effective Time, the
Surviving Corporation shall issue to the Escrow Agent a number of shares of
common stock, par value $0.000001 per share, of the Surviving Corporation
("SURVIVING CORPORATION COMMON STOCK") equal to the total number of Adjusted
Fully Diluted Shares (as defined below) outstanding immediately prior to the
Merger.

     (e) In consideration of the contribution to DT by the Escrow Agent of
Surviving Corporation Common Stock pursuant to Section 1.04(a) hereof, DT shall
issue, in accordance with Section 1.04(a), and deliver to the Escrow Agent, the
maximum number of DT Ordinary Shares (including DT Ordinary Shares underlying DT
Depositary Shares that are to be delivered as part of the Merger Consideration)
that has become payable pursuant to Section 1.05 for delivery to the Merger
Consideration Recipients entitled thereto.

     (f) If, between the date of this Agreement and the Effective Time, all of
the outstanding DT Ordinary Shares, or more than 80% of the outstanding DT
Ordinary Shares pursuant to an exchange offer for all outstanding shares, shall
have been changed into or exchanged for a different number of shares or kind of
shares of DT or another corporation or entity owning more than 80% of the DT
Ordinary Shares, or the DT Ordinary Shares outstanding shall have changed, by
reason of any reclassification, split-up, stock-split, reverse stock-split,
stock dividend, stock combination, recapitalization or redenomination of share
capital, merger or similar statutory procedure or pursuant to an exchange offer,
or DT changes the number of DT Ordinary Shares represented by a DT Depositary
Share, then the Common Stock Exchange Ratio, the Series A and B Preferred
Exchange Ratio, the Series D Preferred Exchange Ratio, the Series E and F
Preferred Exchange Ratio and the amount of any portion of the Merger
Consideration that would otherwise be payable in DT Ordinary Shares and the
issuer thereof and other definitions and provisions of this Agreement dependent
thereon shall be appropriately adjusted.

     (g) In the event that the aggregate number of shares of Powertel Common
Stock and the Powertel Common Stock Equivalents (as defined below) ("ADJUSTED
FULLY DILUTED SHARES") exceeds the Maximum Share Amount as of the Effective
Time, excluding, for purposes of this Section 1.05(g), Powertel Common Stock
issuable after the date hereof and prior to the Effective Time in respect of
dividends accrued on the Series E Preferred Shares and the Series F Preferred
Shares, each of the Common Stock Exchange Ratio, the Series A and B Preferred
Exchange Ratio, the Series D Preferred Exchange Ratio and the Series E and F
Preferred Exchange Ratio shall be adjusted by multiplying each of the Common
Stock Exchange Ratio, the Series A and B Preferred Exchange Ratio, the Series D
Preferred Exchange Ratio and the Series E and F Preferred Exchange Ratio by a
fraction the numerator of which shall be the Maximum Share Amount and the
denominator of which shall be the number of Adjusted Fully Diluted

                                       B-4
<PAGE>   376

Shares as of the Effective Time. Except as described in the preceding sentence,
the number of shares of Powertel Common Stock and Powertel Common Stock
Equivalents for the purpose of such recalculation shall be determined in the
same manner as described in SCHEDULE 2.03, including the shares of Powertel
Stock actually outstanding and shares of Powertel Stock issuable (i) in exchange
for Powertel Preferred Stock, (ii) pursuant to Powertel Stock Options (as
defined below) and Powertel Warrants (as defined below), (iii) pursuant to
Powertel Restricted Stock Awards (as defined below), (iv) in connection with the
Eliska Put Rights, (v) pursuant to the Sonera Stock Purchase Agreement (as
defined below) and (vi) any other Powertel Common Stock and Powertel Common
Stock Equivalents outstanding as of the Effective Time. For purposes of this
Section 1.05(g), the "Maximum Share Amount" means 55,742,000 shares; provided,
however, that if prior to the Effective Time the Stock Purchase Agreement
between Powertel and Sonera B.V. relating to the DiGiPH Transaction (the "SONERA
STOCK PURCHASE AGREEMENT") or the Eliska Put or the Sonera Put shall have been
terminated, the Maximum Share Amount shall be appropriately reduced.

     (h) Warrants.  If all the warrants (the "POWERTEL WARRANTS") to purchase
Powertel Common Stock issued by Powertel pursuant to the Warrant Agreement (the
"POWERTEL WARRANT AGREEMENT") dated February 7, 1996 between Powertel and
Bankers Trust Company, as warrant agent, shall not have been exercised prior to
the Effective Time and any holder of such Powertel Warrants becomes entitled to
DT Ordinary Shares after the Effective Time, such DT Ordinary Shares to which
such holder of Powertel Warrants is entitled will be issued from a U.S. trust,
as described in Annex 1.05(h) (which shall be in form and substance reasonably
satisfactory to DT and Powertel, the "WARRANTS TRUST"), and to the extent any
holder of Powertel Warrants becomes entitled to cash payment after the Effective
Time, such cash payment to which such holder of Powertel Warrants is entitled
will be paid by DT.

     (i) Eliska Partners.

          (i) To the extent that prior to the Effective Time, any of the Eliska
     Partners receives Powertel Common Stock in respect of its rights to sell
     its interest in the Eliska Joint Venture pursuant to (x) the Put Agreement
     dated May 30, 2000 between Powertel and Sonera Holding B.V. (the "SONERA
     PUT") or (y) the Put Agreement dated May 30, 2000 between Powertel, Eliska
     Wireless Investors I, L.P. ("ELISKA") and Sonera Holding B.V. (the "ELISKA
     PUT," and together with the Sonera Put, the "ELISKA PUT RIGHTS"), such
     Eliska Partner shall have all the rights with respect to such Powertel
     Common Stock which a Powertel stockholder has.

          (ii) To the extent that any of the Eliska Partners does not receive
     Powertel Common Stock prior to the Effective Time in respect of its Eliska
     Put Rights, such Eliska Partner shall be entitled to receive DT Ordinary
     Shares, DT Depositary Shares or cash as the case may be, pursuant to the
     Eliska Put Rights. To the extent that, on or after the Effective Time, an
     Eliska Partner is entitled to DT Ordinary Shares, such shares will be
     delivered from a U.S. trust, as described in Annex 1.05(i) (which shall be
     in form and substance reasonably satisfactory to DT and Powertel, the
     "ELISKA PARTNERS SHARES TRUST") and to the extent that such Eliska Partner
     is entitled to cash, such cash shall be paid by DT. The consideration
     payable to an Eliska Partner pursuant to this clause (ii) shall not
     constitute Merger Consideration for the purpose of this Agreement.

          (iii) Prior to the date hereof Powertel, DT and the Eliska Partners
     have entered into an agreement pursuant to which the Eliska Partners have
     consented to the assumption by DT of Powertel's obligations under the
     Eliska Put Rights and the treatment of the Eliska Put Rights as
     contemplated by this Agreement.

     SECTION 1.06.  Surrender and Payment.  (a) Promptly after the Effective
Time, DT shall cause the Surviving Corporation to send, or will cause the Escrow
Agent to send, to each holder of record as of the Effective Time of Powertel
Stock (other than holders of Excluded Powertel Shares) a letter of transmittal
which shall specify that the delivery of Certificates shall be effected, and
risk of loss and title shall pass, only upon proper delivery of a Certificate to
the Escrow Agent, and instructions for use in effecting the surrender to the
Escrow Agent of Certificates in exchange for the Merger Consideration (the

                                       B-5
<PAGE>   377

"LETTER OF TRANSMITTAL"). The Letter of Transmittal shall contain such other
terms and conditions as DT and Powertel may reasonably specify.

     (b) Each record holder of any Powertel Stock (other than Excluded Powertel
Shares) shall, upon surrender to the Escrow Agent of a Certificate or
Certificates representing such shares of Powertel Stock, together with a
properly completed Letter of Transmittal covering the Powertel Stock represented
by such Certificate or Certificates, without further action, be entitled to
receive, and the Escrow Agent shall deliver (and DT shall cause the Escrow Agent
to deliver) to each such holder, subject to Section 1.06(e) below, (i) the
number of whole DT Depositary Shares or DT Ordinary Shares included in the
Merger Consideration in respect of such Powertel Stock, subject to the
provisions of Section 1.05, and (ii) a check in the amount (after giving effect
to any required tax withholdings) of (A) any cash in lieu of Fractional
Interests (as defined below) to be paid pursuant to Section 1.09, plus (B) any
cash dividends or other distributions that such holder has the right to receive
pursuant to Section 1.06(f). Until so surrendered, each such Certificate shall,
after the Effective Time, represent for all purposes only the right to receive
the number of whole DT Depositary Shares or DT Ordinary Shares, as applicable,
to which it is entitled pursuant to Section 1.05 and the applicable amounts of
cash provided in the foregoing clause (ii) of the preceding sentence.

     (c) If any DT Depositary Shares or DT Ordinary Shares are to be delivered
to a Person other than the registered holder of the Powertel Stock represented
by a Certificate or Certificates surrendered with respect thereto, it shall be a
condition to such issuance that the Certificate or Certificates so surrendered
shall be properly endorsed or otherwise be in proper form for transfer and that
the Person requesting such delivery shall pay to the Escrow Agent any transfer
or other taxes required as a result of such delivery to a Person other than the
registered holder of such Powertel Stock or establish to the satisfaction of the
Escrow Agent that such tax has been paid or is not payable.

     (d) The stock transfer books of Powertel shall be closed after the close of
trading on the National Market System (the "NASDAQ") on the trading day
immediately prior to the Effective Time, and thereafter there shall be no
further registration of transfers of Powertel Common Stock that were outstanding
prior to the Effective Time. After the Effective Time, Certificates presented to
the Surviving Corporation for transfer shall be cancelled and exchanged for the
consideration provided for, and in accordance with the procedures set forth, in
this Article 1.

     (e) Any DT Ordinary Shares issued and delivered in respect of Powertel
Stock pursuant to this Article 1 and any cash in lieu of Fractional Interests to
be paid pursuant to Section 1.09, plus any cash dividend or other distribution
that such holder has the right to receive pursuant to Section 1.06(f) that
remains unclaimed by any holder of Powertel Stock six months after the Effective
Time, shall be held by the Escrow Agent (or a successor agent appointed by DT)
or shall be delivered to the Depositary upon the instruction of DT and held by
the Depositary, in either case subject to the instruction of DT, in an account
or accounts designated for such purpose. None of DT, Merger Sub, Powertel, the
Surviving Corporation or the Exchange Agent shall be liable to any holder of
Powertel Stock for any securities delivered or any amount paid by the
Depositary, the Escrow Agent or its nominee, as the case may be, to a public
official which it is so required to pay under applicable abandoned property
laws. Any cash remaining unclaimed by holders of Powertel Stock five years after
the Effective Time (or such earlier date immediately prior to such time as such
cash would otherwise escheat to or become property of any Governmental or
Regulatory Authority or as is otherwise provided by any applicable Legal
Requirement (as defined below)) shall, to the extent permitted by applicable
Legal Requirements, become the property of the Surviving Corporation or DT, as
DT may determine.

     (f) No dividends or other distributions nor any voting rights with respect
to securities of DT issuable to the Escrow Agent with respect to Powertel Stock
shall be paid to or exercised by the holder of any unsurrendered Certificates
until such Certificates are surrendered as provided in this Section. Subject to
the effect of applicable Legal Requirements, upon such surrender, there shall be
issued and/or paid to the holder of DT Depositary Shares or DT Ordinary Shares
issued in exchange therefor, without interest and after giving effect to any
required tax withholding, (A) at the time of such surrender, the dividends or

                                       B-6
<PAGE>   378

other distributions payable with respect to such DT Depositary Shares or DT
Ordinary Shares with a record date after the Effective Time and a payment date
on or prior to the date of such surrender and not previously paid and (B) at the
appropriate payment date, the dividends or other distributions payable with
respect to such DT Depositary Shares or DT Ordinary Shares with a record date
after the Effective Time but with a payment date subsequent to such surrender.
For purposes of dividends or other distributions in respect of DT Depositary
Shares or DT Ordinary Shares, all DT Depositary Shares and DT Ordinary Shares to
be issued pursuant to the Merger shall be deemed issued and outstanding as of
the Effective Time. Notwithstanding the foregoing, no dividends or other
distributions nor any voting rights with respect to securities of DT issuable to
the Escrow Agent for the account of the Options Trustee, the Warrants Trustee,
the Eliska Partners Shares Trustee and the Dissenting Stockholders Trustee shall
be paid to or exercised by any such trustees.

     SECTION 1.07.  [Reserved]

     SECTION 1.08.  Treatment of Powertel Option Plans.  (a) Subject to the
consummation of the Merger, immediately prior to the Effective Time, each
outstanding Powertel Stock Option will be converted (and such Powertel Stock
Option will be extinguished) into a right to acquire (each, a "POWERTEL ROLLOVER
OPTION") from a U.S. trust, as described in Annex 1.08(a) (which shall be in
form and substance reasonably satisfactory to DT and Powertel, the "OPTIONS
TRUST") on the same terms and conditions as were applicable under the Powertel
Stock Option (but taking into account any changes thereto, including any
acceleration thereof, provided for in the option award or in the Powertel Stock
Option Plans listed on SCHEDULE 1.08 and applicable to such Powertel Stock
Options by reason of this Agreement or the transactions contemplated hereby)
that number of DT Ordinary Shares (the "POWERTEL OPTION AMOUNT") determined by
multiplying the maximum number of shares of Powertel Common Stock subject to
such Powertel Stock Option by the Common Stock Exchange Ratio, rounded if
necessary to the nearest whole DT Ordinary Share at an exercise price per DT
Ordinary Share equal to the exercise price per share of Powertel Common Stock in
effect with respect to such Powertel Stock Option immediately prior to the
Effective Time divided by the Common Stock Exchange Ratio. In order to implement
the conversion of the Powertel Stock Options described above, the arrangements
set forth in Annex 1.08(a) will be effected at the Effective Time. In the case
of a Powertel Stock Option which is intended to be an incentive stock option
under Section 422 of the Code, the adjustment in this Section 1.08 shall be
modified if necessary to permit such Powertel Stock Option to continue to comply
with Section 422 of the Code.

     (b) To the extent that any Person would otherwise be entitled to receive a
fraction of a DT Ordinary Share pursuant to this Section 1.08, such fraction
shall be treated in accordance with Section 1.09.

     (c) As soon as practicable after the Effective Time, DT shall cause to be
delivered to the holders of Powertel Stock Options appropriate notices setting
forth such holders' rights pursuant to the respective Powertel Stock Option
Plans and agreements evidencing the grants of such Powertel Stock Options
(including that, in connection with the Merger and to the extent provided by the
terms of the Powertel Stock Option Plans award agreements thereunder, the
Powertel Stock Options subject to change of control vesting have become fully
vested).

     (d) No later than the Effective Time, DT shall file or cause to be filed
with the SEC a registration statement on an appropriate form or a post-effective
amendment to a previously filed registration statement under the Securities Act
with respect to the DT Ordinary Shares and DT Depositary Shares which are
subject to the Powertel Rollover Options as provided in Section 1.08(a), and
shall use reasonable best efforts to maintain the current status of the
prospectus associated therewith, as well as to comply with any applicable state
securities or "blue sky" laws for so long as such options remain outstanding.

     SECTION 1.09.  Fractional DT Depositary Shares and Fractional DT Ordinary
Shares.  No fraction of a DT Depositary Share or a DT Ordinary Share will be
issued to holders of Powertel Stock, but each holder of Powertel Stock otherwise
entitled to receive a fraction of a DT Depositary Share or DT Ordinary Share
will be entitled to receive in accordance with the provisions of this Section
1.09 from the Escrow Agent a cash payment in lieu of such fraction of a DT
Depositary Share or DT Ordinary Share, as

                                       B-7
<PAGE>   379

applicable (each a "FRACTIONAL INTEREST") representing such holder's
proportionate interest in the net proceeds from the sale by the Escrow Agent on
behalf of all such holders of the aggregate of the fractions of DT Depositary
Shares and DT Ordinary Shares which would otherwise be issued ("EXCESS ADSs" and
"EXCESS SHARES", respectively). The sale of the Excess ADSs and the Excess
Shares by the Escrow Agent shall be executed on the New York Stock Exchange,
Inc. (the "NYSE") and the Frankfurt Stock Exchange (the "FSE"), respectively,
through one or more member firms of the NYSE or the FSE, as the case may be, and
shall be executed in round lots to the extent practicable. Until the net
proceeds of such sale or sales have been distributed to the holders of Powertel
Stock otherwise entitled to receive Fractional Interests, the Escrow Agent will
hold such proceeds in trust for such holders of Powertel Stock (the "POWERTEL
STOCK TRUST"). DT shall pay all commissions, transfer taxes and other
out-of-pocket transaction costs, including the expenses and compensation, of the
Escrow Agent incurred in connection with such sale of the Excess ADSs and Excess
Shares. The Escrow Agent shall determine the portion of the Powertel Stock Trust
to which each holder of Powertel Stock shall be entitled, if any, by multiplying
the amount of the aggregate net proceeds comprising the Powertel Stock Trust by
a fraction, the numerator of which is the amount of Fractional Interests to
which such holder of Powertel Stock is entitled and the denominator of which is
the aggregate amount of Fractional Interests to which all holders of Powertel
Stock are entitled. As soon as practicable after the determination of the amount
of cash, if any, to be paid to holders of Powertel Stock in lieu of any
Fractional Interests, the Escrow Agent shall make available such amounts to such
holders of Powertel Stock without interest.

     SECTION 1.10.  The Surviving Corporation.  (a) The certificate of
incorporation of Powertel in effect at the Effective Time shall, by virtue of
the Merger, be amended and restated as of the Effective Time to be identical to
the certificate of incorporation of Merger Sub (except that Article 1 thereof
shall read: "The name of the Corporation is Powertel, Inc." and, as so amended
and restated, shall be the certificate of incorporation of the Surviving
Corporation until amended in accordance with applicable law).

     (b) The bylaws of Merger Sub in effect at the Effective Time shall be the
bylaws of the Surviving Corporation until amended in accordance with applicable
law.

     (c) The directors of Merger Sub and the officers of Powertel immediately
prior to the Effective Time shall be the directors and officers of the Surviving
Corporation, respectively, and such individuals shall serve in such positions
until their successors shall have been duly elected and shall qualify.

     SECTION 1.11.  Lost, Stolen or Destroyed Certificates.  In the event any
Certificate shall have been lost, stolen or destroyed, upon the holder's
compliance with the replacement requirements established by the Escrow Agent,
including, if necessary, the posting by such Person of a bond in customary
amount as indemnity against any claim that may be made against it with respect
to such Certificate, the Escrow Agent will issue (or cause to be issued) in
exchange for such lost, stolen or destroyed Certificate, the Merger
Consideration and any cash payable in lieu of Fractional Interests and any
unpaid dividends or other distributions deliverable pursuant to Section 1.06(f)
in respect of the Powertel Stock represented by such Certificate pursuant to
this Agreement.

     SECTION 1.12.  Dissenting Shares.  Series A, B, D, E and F Preferred Shares
which are issued and outstanding immediately prior to the Effective Time and
which are held by a holder who has not voted such shares in favor of the Merger,
who shall have delivered a written demand for appraisal of such shares in the
manner provided by Delaware Law and who shall not have effectively withdrawn or
lost such right to appraisal as of the Effective Time ("DISSENTING SHARES"),
shall be entitled to such rights (but only such rights) as are granted by
Section 262 of the Delaware Law. Each holder of Dissenting Shares who becomes
entitled to payment for such Dissenting Shares pursuant to Section 262 of the
Delaware Law shall receive payment therefor from the Surviving Corporation in
accordance with Delaware Law; provided, however, that (i) if any such holder of
Dissenting Shares shall have failed to establish his entitlement to appraisal
rights as provided in Section 262 of the Delaware Law, (ii) if any holder of
Dissenting Shares shall have effectively withdrawn his demand for appraisal of
such shares or lost his right to appraisal and payment for his shares under
Section 262 of the Delaware Law or (iii) if neither any holder of Dissenting
Shares nor the Surviving Corporation shall have filed a petition demanding a

                                       B-8
<PAGE>   380

determination of the value of all Dissenting Shares within the time provided for
the filing of such petition in Section 262 of the Delaware Law, such holder
shall forfeit the right to appraisal of such Dissenting Shares and each such
share shall be converted into the right to receive the Merger Consideration
pursuant to Section 1.05(b). Powertel shall give DT prompt notice of any demands
received by Powertel for appraisal of Powertel Preferred Stock and DT shall have
the right to conduct all negotiations and proceedings with respect to such
demands. Except with the prior written consent of DT, Powertel shall not make
any payment with respect to, or settle or offer to settle, any such demands. To
the extent holders of Dissenting Shares become entitled to DT Ordinary Shares
after the Effective Time, such DT Ordinary Shares to which such holder of
Dissenting Shares is entitled will be issued from the Dissenting Stockholder
Trust described in Annex 1.12 (the "DISSENTING STOCKHOLDER TRUST").

                                   ARTICLE 2

                   REPRESENTATIONS AND WARRANTIES OF POWERTEL

     Except as disclosed in Powertel Filed SEC Documents (as defined below) and
except as set forth in the Powertel disclosure schedules attached to this
Agreement (it being agreed that disclosure of any item in the schedules shall be
deemed disclosure with respect to any section of this Agreement to which the
relevance of such item is reasonably apparent), Powertel hereby represents and
warrants as of the date hereof to DT as follows:

     SECTION 2.01.  Organization.  Each of Powertel and its Subsidiaries
(collectively, the "POWERTEL SUBSIDIARIES") is a corporation or limited
liability company duly organized, validly existing and is in good standing
(where such concept is applicable) under the laws of the jurisdiction of its
incorporation or organization and has the requisite power and authority to carry
on its business as now being conducted, except where the failure to be so
organized, existing and in good standing or to have such power and authority
could not reasonably be expected to have a Material Adverse Effect on Powertel
or prevent or materially delay the consummation of the Merger. Powertel and each
of the Powertel Subsidiaries is duly qualified or licensed to do business and is
in good standing (where such concept is applicable) in each jurisdiction in
which the nature of its business or the ownership or leasing of its properties
makes such qualification or licensing necessary, except in such jurisdictions
where the failure to be so duly qualified or licensed and in good standing could
not reasonably be expected to have a Material Adverse Effect on Powertel or
prevent or materially delay the consummation of the Merger. Powertel has
delivered to DT complete and correct copies of the Restated Certificate of
Incorporation of Powertel and Restated By-laws of Powertel and has made
available to DT the certificate of incorporation and by-laws (or similar
organizational documents) of each of the Powertel Subsidiaries.

     SECTION 2.02.  Subsidiaries.  SCHEDULE 2.02 lists each Powertel Subsidiary
and any Investment Entity. All of the outstanding shares of capital stock of
each Powertel Subsidiary that is a corporation have been validly issued and are
fully paid and nonassessable. All of the outstanding shares of capital stock of
each Powertel Subsidiary are owned by Powertel or by another Powertel Subsidiary
free and clear of all Liens, except for Liens which are granted to secure
indebtedness and are disclosed in SCHEDULE 2.02. Except as set forth in SCHEDULE
2.02, (i) Powertel and the Powertel Subsidiaries have no material ongoing
obligations, agreements, commitments, rights, understandings or arrangements
with respect to any Investment Entities, including funding obligations; and (ii)
all Investment Interests are owned by Powertel or the Powertel Subsidiaries free
and clear of all Liens. Except as set forth in SCHEDULE 2.02 and except for the
capital stock owned by Powertel, directly or indirectly, in the Powertel
Subsidiaries, neither Powertel nor any of the Powertel Subsidiaries owns,
directly or indirectly, any capital stock or other ownership interest in any
corporation, partnership, joint venture, limited liability company or other
entity.

     SECTION 2.03.  Capital Structure.  The authorized capital stock of Powertel
consists of 401,000,000 shares of capital stock of which 400,000,000 shares are
authorized to be issued as Powertel Common Stock and 1,000,000 shares are
authorized to be issued as Powertel Preferred Stock. As of the close of business
on August 18, 2000, Powertel had 31,381,461 shares of Powertel Common Stock
issued and outstanding (not including 33,165 shares of restricted stock issued

employees below the director level, such list need only set forth the aggregate

or shares of capital stock of any Powertel Subsidiary were issued, reserved for
issuance or outstanding and there are no stock appreciation rights, phantom

Powertel Stock Options, the Powertel Warrants, the Eliska Put Rights, the

stockholders may vote. Except as set forth above or in SCHEDULE 2.02 OR SCHEDULE

     Except as set forth in SCHEDULE 2.02 OR SCHEDULE 2.03, as of the date of
this Agreement, there are no outstanding contractual obligations of Powertel or
any of the Powertel Subsidiaries to repurchase, redeem or otherwise acquire any
shares of capital stock of Powertel or any of the Powertel Subsidiaries.

     Between August 18, 2000 and the date of this Agreement, no Powertel Common

     SECTION 2.04.  Authority.  The Board of Directors of Powertel, at a meeting

Merger and the Powertel Stockholder Agreements, (ii) determining that the Merger

recommending that Powertel's stockholders approve and adopt this Agreement.
Powertel has requisite corporate power and authority to execute and deliver this
Agreement and the other agreements to which it is a party that are referenced
herein and, subject to the adoption and approval of this Agreement by (i) a
majority of the votes entitled to be cast by the holders of all outstanding
shares of Powertel Common Stock and Series A Preferred Shares, voting on an
as-if-converted to Powertel Common Stock basis and voting together with the
holders of Powertel Common Stock as a single class, and (ii) two-thirds of each
class of the Series A Preferred Shares, Series B Preferred Shares, Series D
Preferred Shares, Series E Preferred Shares and Series F Preferred Shares, each
such class of preferred stock voting as a single class (collectively, the
"POWERTEL STOCKHOLDER APPROVAL"), to consummate the transactions contemplated
hereby. The execution, delivery and performance of this Agreement by Powertel
and the consummation by Powertel of the Merger and of the other transactions
contemplated hereby have been duly authorized by all necessary corporate action
on the part of Powertel, subject to the Powertel Stockholder Approval. This
Agreement has been duly executed and delivered by Powertel and (assuming the
valid authorization, execution and delivery of this Agreement by DT) constitutes
the valid and binding obligation of Powertel enforceable against Powertel in
accordance with its terms, except that such enforceability (i) may be limited by
bankruptcy, insolvency, reorganization, moratorium or other similar laws
affecting or relating to the enforcement of creditors' rights and remedies
generally, and (ii) is subject to general principles of equity (regardless of
whether considered in a proceeding in equity or at law).

     SECTION 2.05.  No Conflict; Required Filings and Consents.  (a) Except as
set forth in subsection (b) below or as set forth in SCHEDULE 2.05, neither the
execution, delivery or performance (assuming such performance occurred on the
date hereof) of this Agreement by Powertel nor the consummation by Powertel of
the transactions contemplated hereby will (i) violate or conflict with the
Restated Certificate of Incorporation or Restated By-laws of Powertel or of the
similar organizational documents of any of the
                                      B-11
<PAGE>   383

Powertel Subsidiaries, (ii) result in a violation or breach of, or constitute
(with or without due notice or lapse of time or both) a default (or give rise to
any right of termination, amendment, cancellation or acceleration) under, any of
the terms, conditions or provisions of any note, bond, mortgage, indenture,
lease, license, contract, agreement or other instrument or obligation to which
Powertel or any of the Powertel Subsidiaries is a party or by which any of their
properties are bound, (iii) violate any law, court order, judgment, decree or
regulation applicable to Powertel or any of the Powertel Subsidiaries or by
which any of their respective properties are bound, or (iv) result in the
creation or imposition of any Lien on any asset of Powertel or the Powertel
Subsidiaries, except in the case of clauses (ii), (iii) or (iv) for violations,
breaches or defaults that could not reasonably be expected to have a Material
Adverse Effect on Powertel or prevent or materially delay the consummation of
the Merger.

     (b) Except for filings, permits, authorizations, consents and approvals as
may be required under, and other applicable requirements of, the Securities Act,
state securities or "Blue Sky" laws, the Exchange Act, the Communications Act,
the HSR Act, Council Regulation (EEC) No. 4064/89, if applicable, Delaware Law,
the rules, regulations and published decisions of the FAA, the FCC and state
public utility or service commissions or similar agencies, or the rules and
regulations of the Nasdaq or as specified in SCHEDULE 2.05 (collectively,
"POWERTEL REQUIRED APPROVALS"), neither the execution, delivery or performance
of this Agreement by Powertel nor the consummation by Powertel of the
transactions contemplated hereby will require any filing with, or permit,
authorization, consent or approval of, any Governmental or Regulatory Authority
(except where the failure to obtain such permit, authorization, consent or
approval or to make such filings could not reasonably be expected to have a
Material Adverse Effect on Powertel or prevent or materially delay the
consummation of the Merger).

     SECTION 2.06.  SEC Filings; Financial Statements.  Powertel has filed with
the SEC all documents required to be filed by it since January 1, 1997 under the
Securities Act or the Exchange Act (the "POWERTEL SEC DOCUMENTS"). As of their
respective filing dates, the Powertel SEC Documents were prepared substantially
in accordance with the requirements of the Securities Act or the Exchange Act,
as the case may be, each as in effect on the date so filed, and at the time
filed with the SEC (or if amended or superseded by a filing prior to the date
hereof, then on the date of such filing) none of the Powertel SEC Documents
contained any untrue statement of a material fact or omitted to state a material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances under which they were made, not misleading. The
financial statements of Powertel included in the Powertel SEC Documents have
been prepared in accordance with GAAP (except in the case of the unaudited
statements, as permitted by Form 10-Q under the Exchange Act) applied on a
consistent basis during the periods involved (except as may be indicated therein
or in the notes thereto) and fairly present the consolidated financial position
of Powertel and the consolidated Powertel Subsidiaries as of the respective
dates thereof and the consolidated results of operations and consolidated cash
flows for the periods then ended (subject, in the case of unaudited statements,
to normal year-end audit adjustments and to any other adjustments described
therein).

     SECTION 2.07.  Absence of Certain Changes or Events.  Except as disclosed
in SCHEDULE 2.07 or in the documents filed by Powertel with the SEC and publicly
available prior to the date of this Agreement (the "POWERTEL FILED SEC
DOCUMENTS"), since December 31, 1999, Powertel and the Powertel Subsidiaries
have conducted their respective businesses in all material respects only in the
ordinary course, consistent with past practices, and there has not been (i) any
Material Adverse Change with respect to Powertel, (ii) any declaration, setting
aside or payment of any dividend or other distribution with respect to its
capital stock (other than regularly scheduled dividends on the Series E
Preferred Shares and Series F Preferred Shares) or any redemption, purchase or
other acquisition of any of its capital stock, (iii) any split, combination or
reclassification of any of its capital stock or any issuance or the
authorization of any issuance of any other securities in respect of, in lieu of
or in substitution for shares of its capital stock, or (iv) any change in
accounting methods, principles or practices by Powertel affecting its assets,
liabilities or business, except insofar as may have been required by a change in
GAAP.

     SECTION 2.08.  Information Provided by Powertel.  None of the information
supplied or to be supplied by Powertel specifically for inclusion or
incorporation by reference in (i) the DT Registration

                                      B-12

or supplements thereto, the "POWERTEL PROXY STATEMENT") relating to the Powertel
Stockholders' Meeting (as defined below) and the prospectus included in the DT

Depositary Shares pursuant to the Merger, will, in the case of the DT
Registration Statement, at the time it becomes effective, contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary in order to make the statements therein, in light of
the circumstances under which they were made, not misleading, or in the case of
the Powertel Proxy Statement, at the time of the mailing of the Powertel Proxy
Statement or the time of the Powertel Stockholders' Meeting, contain any untrue

Statement will comply (with respect to Powertel) as to form in all material
respects with the requirements of the Securities Act, and the Powertel Proxy
Statement will comply (with respect to Powertel) as to form in all material
respects with the requirements of the Exchange Act. None of the information

incorporation by reference in the German Listing Prospectus will, at the time
the German Listing Prospectus is published, contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein

light of the circumstances under which they were made, not misleading. None of
the information to be supplied by or on behalf of Powertel pursuant to Section
5.06(d) will contain any untrue statement of material fact or omit to state any
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. Powertel makes no representation or warranty with respect to any
information supplied by DT or any other Person who is not an Affiliate of
Powertel that is contained in the DT Registration Statement, Powertel Proxy
Statement, the German Listing Prospectus or the auditor's report to be prepared
pursuant to Section 183(3) of the German Act.

     SECTION 2.09.  Permits; Compliance with Laws.  (a) Each of Powertel and the
Powertel Subsidiaries is in possession of all franchises, grants,
authorizations, licenses, permits, charters, easements, variances, exceptions,
consents, certificates, approvals and orders of any Governmental or Regulatory
Authority necessary for Powertel or any of the Powertel Subsidiaries to own,
lease and operate its properties or to carry on its business as it is now being
conducted (the "POWERTEL PERMITS"), except where the failure to have any of the
Powertel Permits could not, individually or in the aggregate, have a Material
Adverse Effect on Powertel, and, as of the date of this Agreement, no suspension
or cancellation of any of the Powertel Permits is pending or, to the Knowledge
of Powertel, threatened, except where the suspension or cancellation of any of
the Powertel Permits could not, individually or in the aggregate, reasonably be
expected to have a Material Adverse Effect on Powertel. The business of Powertel
and the Powertel Subsidiaries is not being conducted in violation of any
applicable law, ordinance regulation, judgement, order or decree of any
Governmental or Regulatory Authority ("LEGAL REQUIREMENTS"), except for possible
violations that could not reasonably be expected to have a Material Adverse
Effect on Powertel or prevent or materially delay the consummation of the
Merger. None of the representations made in this Section 2.09 are being made
with respect to Environmental Laws.

     (b) Except as set forth in SCHEDULE 2.09:

          (i) Powertel and each of the Powertel Subsidiaries holds, and is
     qualified and eligible to hold, all material licenses, permits and other
     authorizations issued or to be issued by the FCC to such entity for the
     operation of their respective businesses, all of which are set forth in
     SCHEDULE 2.09(b)(i) (the "POWERTEL FCC LICENSES"). Each of the Powertel FCC
     Licenses that is subject to restrictions under Section 310(b) of the
     Communications Act is held by a Powertel Subsidiary.

                                      B-13
<PAGE>   385

          (ii) The Powertel FCC Licenses are valid and in full force and effect,
     and neither Powertel nor any of the Powertel Subsidiaries is or has been
     delinquent in payment on or in default under any installment obligation
     owed to the United States Treasury in connection with the Powertel FCC
     Licenses. As used herein, the term "full force and effect" means that (A)
     the orders issuing the Powertel FCC Licenses have become effective, (B) no
     stay of effectiveness of such orders has been issued by the FCC, and (C)
     the Powertel FCC Licenses have not been invalidated by any subsequent
     published FCC action.

          (iii) All material reports and applications required by the
     Communications Act or required to be filed with the FCC by Powertel or any
     of the Powertel Subsidiaries have been filed and are accurate and complete
     in all material respects.

          (iv) Powertel and the Powertel Subsidiaries are, and have been, in
     compliance in all material respects with, and the wireless communications
     systems operated pursuant to the Powertel FCC Licenses are and have been
     operated in compliance in all material respects with, the Communications
     Act.

          (v) There is not pending or, to Powertel's Knowledge, threatened as of
     the date hereof any application, petition, objection, pleading or
     proceeding with the FCC or any public service commission or similar body
     having jurisdiction or authority over the communications operations of
     Powertel or any of the Powertel Subsidiaries which is reasonably likely to
     result in the revocation, cancellation, suspension, dismissal, denial or
     any materially adverse modification of any Powertel FCC License or
     imposition of any substantial fine or forfeiture against Powertel or any of
     the Powertel Subsidiaries.

          (vi) No facts are known to Powertel or the Powertel Subsidiaries which
     if known by a Governmental or Regulatory Authority of competent
     jurisdiction would present a substantial risk that any Powertel FCC License
     could be revoked, cancelled, suspended or materially adversely modified or
     that any substantial fine or forfeiture could be imposed against Powertel
     or any of the Powertel Subsidiaries.

          (vii) Powertel and the Powertel Subsidiaries have not made any
     material misstatements of fact, or omitted to disclose any fact, to any
     Government Entity or in any report, document or certificate filed
     therewith, which misstatements or omissions, individually or in the
     aggregate, could reasonably be expected to subject any material Powertel
     FCC Licenses to revocation or failure to renew, except to the extent that
     such revocation or failure to renew would not have a Material Adverse
     Effect on Powertel or the transactions contemplated by this Agreement.

     SECTION 2.10.  Tax Matters.  Except as set forth in SCHEDULE 2.10 or as
would not have a Material Adverse Effect on Powertel: (i) Powertel and each of
the Powertel Subsidiaries have timely filed (after taking into account any
extensions to file) all Tax Returns required to be filed by them either on a
separate or combined or consolidated basis; (ii) all such Tax Returns are
correct in all respects and accurately disclose in all respects all Taxes
required to be paid for the periods covered thereby; (iii) Powertel and the
Powertel Subsidiaries have paid or caused to be paid all Taxes shown as due on
such Tax Returns and all Taxes for which no Tax Return was required to be filed,
and the financial statements contained in the Powertel SEC Documents reflect an
adequate reserve as determined in accordance with GAAP for all material Taxes
payable by Powertel and the Powertel Subsidiaries and not yet due (other than a
reserve for deferred Taxes established to reflect timing differences between
book and Tax treatment) for all taxable periods and portions thereof accrued
through the date of such financial statements; (iv) none of Powertel or any
Powertel Subsidiary has waived in writing any statute of limitations in respect
of Taxes; (v) there is no action, suit, investigation, audit, claim or
assessment that has been formally commenced or proposed to Powertel in writing
with respect to Taxes of Powertel or any of the Powertel Subsidiaries where an
adverse determination is reasonably likely; (vi) there are no Liens for Taxes
upon the assets of Powertel or any Powertel Subsidiary except for Liens relating
to current Taxes not yet due; (vii) all Taxes which Powertel or any Powertel
Subsidiary is required by law to withhold or to collect for payment have been
duly withheld and collected, and have been paid or accrued on the books of
Powertel or such Powertel Subsidiary; (viii) neither Powertel nor any Powertel
Subsidiary

                                      B-14
<PAGE>   386

has been a member of any group of corporations filing Tax Returns on a
consolidated, combined, unitary or similar basis other than each such group of
which it is currently a member; (ix) no deduction of any amount that would
otherwise be deductible by Powertel or any of the Powertel Subsidiaries with
respect to taxable periods ending on or before the Effective Time could be
disallowed under Section 162(m) of the Code; (x) neither Powertel nor any of the
Powertel Subsidiaries has constituted either a "distributing corporation" or a
"controlled corporation" in a distribution of stock qualifying for tax-free
treatment under Section 355 of the Code (a) in the two years prior to the date

of a "plan" or "series of related transactions" (within the meaning of Section
355(e) of the Code) in conjunction with the Merger; (xi) neither Powertel nor
any of the Powertel Subsidiaries is a "United States real property holding
corporation" within the meaning of Section 897(c)(2) of the Code; (xii) neither
Powertel nor DT will be obligated to make a payment, in connection with the
transactions contemplated hereunder or otherwise, to any employee or former
employee of, or individual providing services to, Powertel or Powertel
Subsidiaries that would be a "parachute payment" to a "disqualified individual"
as those terms are defined in Section 280G of the Code without regard to whether
such payment is reasonable compensation for personal services performed or to be
performed in the future; and (xiii) none of Powertel, the Powertel Subsidiaries
or DT will be obligated to pay any excise taxes or similar taxes imposed on any
employee or former employee of, or individual providing services to, Powertel or
the Powertel Subsidiaries under Section 4999 of the Code or any similar
provisions as a result of the consummation of the transactions contemplated
hereby, either alone or in connection with any other event.

     SECTION 2.11.  Liabilities.  Except as set forth in Powertel Filed SEC
Documents or SCHEDULE 2.11, and as permitted by this Agreement and the
Alternative Merger Agreement, Powertel and the Powertel Subsidiaries, taken as a
whole, do not have any liabilities or obligations of any nature (whether
accrued, absolute, contingent or otherwise) required by GAAP to be set forth on
a consolidated balance sheet of Powertel and the Powertel Subsidiaries or in the
notes thereto, other than (i) liabilities and obligations incurred in the
ordinary course of business since December 31, 1999 or (ii) liabilities arising
after December 31, 1999 which could not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect on Powertel.

     SECTION 2.12.  Benefit Plans; Employees and Employment Practices.

     (a) Except as disclosed in the Powertel Filed SEC Documents or SCHEDULE
2.12(a) or to the extent required by law or required to maintain in compliance
with provisions of the Code, neither Powertel nor any of the Powertel
Subsidiaries has adopted or amended in any material respect any ERISA Benefit
Plan since the date of the most recent audited financial statements included in
the Powertel Filed SEC Documents. Except as set forth in SCHEDULE 2.12(a),
Powertel does not have any commitment to create, adopt or contribute to any
Powertel Benefit Plan. Except as disclosed in SCHEDULE 2.12(a) or in the
Powertel Filed SEC Documents, as of the date of this Agreement, there exist no
material employment, consulting, severance, bonus, incentive or termination
agreements between Powertel or any of the Powertel Subsidiaries and any current
or former employee, officer or director of Powertel or any of the Powertel
Subsidiaries.

     (b) SCHEDULE 2.12(b) contains a list of all the material Powertel Benefit
Plans. None of Powertel, any of the Powertel Subsidiaries, any officer of
Powertel or any of the Powertel Subsidiaries or any of the ERISA Benefit Plans
has on or before the date of this Agreement engaged in a "prohibited
transaction" (as defined in Section 406 of ERISA or Section 4975 of the Code)
with respect to any ERISA Benefit Plan that could reasonably be expected to
subject Powertel, any of the Powertel Subsidiaries or any officer of Powertel or
any of the Powertel Subsidiaries to any Tax on prohibited transactions imposed
by Section 4975 of the Code or to any liability under Section 502(i) or (l) of
ERISA where such Tax or liability has or would be reasonably expected to have a
Material Adverse Effect on Powertel. No ERISA Benefit Plan has incurred any
"accumulated funding deficiency" (as defined in Section 412 of the Code or Part
3 of Title I or ERISA), whether or not waived. Neither Powertel nor any of the
Powertel Subsidiaries has incurred and none of such entities reasonably expects
to incur, any material liability to the PBGC with respect to any ERISA Benefit
Plan. No assets of Powertel or any of the Powertel Subsidiaries
                                      B-15
<PAGE>   387

are subject to liens arising under ERISA or the Code on account of any ERISA
Benefit Plan, neither Powertel nor any of the Powertel Subsidiaries has been
required to provide any security under Sections 401(a)(29) or 412(f) of the
Code, or under Section 307 of ERISA, and, to Powertel's Knowledge, no event has
occurred that could give rise to any such lien or a requirement to provide any
such security. Except as disclosed in SCHEDULE 2.12(b), none of Powertel, the
Powertel Subsidiaries or any ERISA Affiliate has at any time during the
five-year period preceding the date hereof contributed to any "multiemployer
plan" (as defined in Section 3(37) of ERISA).

     (c) Except as disclosed in SCHEDULE 2.12(c), and except for such matters as
could not be reasonably expected to have a Material Adverse Effect on Powertel,
to the extent applicable, (i) each ERISA Benefit Plan complies with the
requirements of ERISA and the Code, (ii) each ERISA Benefit Plan intended to be
qualified under Section 401(a) of the Code has been determined by the Internal
Revenue Service to be so qualified and nothing has occurred since the date of
that determination that could reasonably be expected to adversely affect the
qualified status of such plan and its related trust is tax-exempt and has been
so since its creation, and (iii) each Powertel Benefit Plan has been maintained,
administered and operated in compliance with its terms and with the requirements
prescribed by any and all statutes, orders, rules and regulations, including but
not limited to ERISA and the Code, which are applicable to such Powertel Benefit
Plans.

     (d) Except as disclosed in SCHEDULE 2.12(d), all material contributions,
reserves or premium payments under or to Powertel Benefit Plans, accrued to the
date hereof have been made or provided for.

     (e) Except as disclosed in SCHEDULE 2.12(e), and except for any liability
as could not be reasonably expected to have a Material Adverse Effect on
Powertel, Powertel has not incurred any liability under Subtitle C or D of Title
IV of ERISA with respect to any "single-employer plan" within the meaning of
Section 4001(a)(15) of ERISA, currently or formerly maintained by Powertel, or
any entity which is considered one employer with Powertel under Section 4001 of
ERISA.

     (f) Except as disclosed in SCHEDULE 2.12(f) neither Powertel nor any of the
Powertel Subsidiaries has any obligation to provide retiree health or welfare
benefits for any current or former employee under any Powertel Benefit Plan,
except as required by Part 6 of Title I of ERISA or to avoid excise taxes under
Section 4980B of the Code, and the terms of Powertel Benefit Plans permit
Powertel to amend or terminate such Powertel Benefit Plans at any time without
incurring liability thereunder.

     (g) Except as disclosed in SCHEDULE 2.12(g), Powertel has not engaged in,
nor is it a successor or parent corporation to an entity that has engaged in a
transaction described in Section 4069 of ERISA.

     (h) Except as disclosed in SCHEDULE 2.12(h), the consummation or
announcement of any transaction contemplated by this Agreement will not (either
alone or upon the occurrence of any additional or further acts or events) result
in any (i) payment (whether of severance pay or otherwise) becoming due from
Powertel or any of the Powertel Subsidiaries to any officer, employee, former
employee or director thereof or to the trustee under any "rabbi trust" or
similar arrangement; (ii) benefit under any Powertel Benefit Plan being
established or becoming accelerated, vested or payable; or (iii) "reportable
event" (as defined in Section 4043 of ERISA) with respect to any ERISA Benefit
Plan subject to Title IV of ERISA.

     (i) Except as disclosed in SCHEDULE 2.12(i), as of the date of this
Agreement there are no pending disputes, arbitrations, claims, suits, grievances
or, to the Knowledge of Powertel, governmental audits involving a Powertel
Benefit Plan (other than routine claims for benefits payable under any such
Powertel Benefit Plan or routine audits) that would reasonably be expected
either individually or in the aggregate, to have a Material Adverse Effect on
Powertel.

     (j) SCHEDULE 2.12(j) contains a list setting forth the name and current
annual salary and other material compensation payable to each Significant
Employee, and the profit sharing, bonus or other form of additional cash
compensation paid or payable by Powertel or the Powertel Subsidiaries to or for
the benefit of each such person for the current fiscal year. Except as set forth
in SCHEDULE 2.12(j), there are no oral or written contracts, agreements or
arrangements obligating Powertel or any of the Powertel Subsidiaries to increase
the compensation or benefits presently being paid or hereafter payable to any
                                      B-16
<PAGE>   388

Significant Employees or any oral employment or consulting or similar
arrangements regarding any Significant Employee that are not terminable without
liability on thirty days' or less prior notice. SCHEDULE 2.12(j) lists all
written employment and consulting agreements with respect to any Significant

Significant Employee prior to, on, or subsequent to the Effective Time),
compensable time or pay, including salary, commission and bonuses, personal time
or pay or vacation time or vacation pay attributable to service rendered on or
prior to the Effective Time the aggregate amount of which exceeds $50,000 for
any Significant Employee. Except as disclosed in SCHEDULE 2.12(j) and other than
claims made in the ordinary course of business consistent with past practice in
an aggregate amount not to exceed $500,000 neither Powertel nor any of the
Powertel Subsidiaries have any liability arising out of claims made or suits
brought (including workers' compensation claims and claims or suits for
contribution to, or indemnification of, third parties, occupational health and
safety, environmental, consumer protection or equal employment matters) for
injury, sickness, disease, discrimination, death or termination of employment of
any Significant Employee, or other employment matter to the extent attributable
to an event occurring or a state of facts existing on or prior to the Effective
Time.

     (k) Except as set forth on SCHEDULE 2.12(k), Powertel and each of the
Powertel Subsidiaries (i) is in compliance with all applicable federal and state
laws, rules and regulations respecting employment, employment practices, terms
and conditions of employment and wages and hours, in each case, with respect to
Powertel Employees, except where the failure to be in compliance would not,
singly or in the aggregate, have a Material Adverse Effect on Powertel or any of
the Powertel Subsidiaries or their financial condition or business; (ii) has
withheld all amounts required by law or by agreement to be withheld from the
wages, salaries and other payments to Powertel Employees; (iii) is not liable
for any arrears of wages or any taxes or any penalty for failure to comply with

liable for any payment to any trust or other fund or to any governmental or
administrative authority, with respect to unemployment compensation benefits,
Social Security or other benefits for Powertel Employees.

     (l) Except as disclosed in SCHEDULE 2.12(l), as of the date of this
Agreement there are no controversies, strikes, work stoppages or disputes
pending or to Powertel's Knowledge threatened against Powertel or any of the
Powertel Subsidiaries, and no organizational effort by any labor union or other
collective bargaining unit currently is under way with respect to any employee,
which in any such case would reasonably be expected to have a Material Adverse
Effect on Powertel. None of Powertel or any of the Powertel Subsidiaries is a
party to a collective bargaining agreement. Except as set forth in SCHEDULE
2.12(l), there is no, and there is not threatened, any labor dispute, grievance
or litigation relating to labor, safety or discrimination matters involving any
Powertel Employee including charges of unfair labor practices or discrimination
complaints, which, if adversely determined, would reasonably be expected to
have, individually or in the aggregate, a Material Adverse Effect on Powertel.
There has been no engagement in any unfair labor practices by Powertel or the
Powertel Subsidiaries within the meaning of the National Labor Relations Act
which would reasonably be expected to have, individually or in the aggregate, a
Material Adverse Effect on Powertel.

     SECTION 2.13.  Litigation.  Except as disclosed in SCHEDULE 2.13 or in the
Powertel Filed SEC Documents, as of the date of this Agreement, there is no
suit, action, proceeding or investigation pending or, to Powertel's Knowledge,
threatened, against Powertel or any of the Powertel Subsidiaries before any
Governmental or Regulatory Authority that, individually or in the aggregate,
would reasonably be expected to have a Material Adverse Effect on Powertel or
prevent or materially delay the consummation of the Merger. Except as disclosed
in SCHEDULE 2.13 or in the Powertel Filed SEC Documents, neither Powertel nor
any of the Powertel Subsidiaries is subject to any outstanding judgment, order,
writ, injunction or

                                      B-17
<PAGE>   389

decree that would, individually or in the aggregate, reasonably be expected to
have a Material Adverse Effect on Powertel.

     SECTION 2.14.  Environmental Matters.  Except for such matters that,

Powertel Subsidiaries has complied and is in compliance with all applicable
Environmental Laws; (ii) the properties currently owned or operated by Powertel
or any of the Powertel Subsidiaries (including soils, groundwater, surface

transmissions); and (vi) to Powertel's Knowledge, neither Powertel nor any of
the Powertel Subsidiaries is subject to any orders, decrees, injunctions or

relating to liability under any Environmental Law or relating to Hazardous
Substances (except for such agreements entered into by Powertel in the ordinary
course of business).

     SECTION 2.15.  Section 203 of the Delaware Law.  The Board of Directors of
Powertel has approved this Agreement, the Merger and the Stockholders Agreement
and the transactions contemplated hereby, with the effect that the restrictions
on business combinations contained in Section 203 of the Delaware Law will not
apply to DT as a result of this Agreement, the Merger and the Stockholders
Agreement. To Powertel's Knowledge, (i) no anti-takeover statute or similar law
of Georgia or Delaware imposes restrictions which could reasonably be expected
to adversely affect or delay the consummation of the transactions contemplated
by this Agreement, and (ii) no "control share acquisition," "fair price,"
"moratorium" or other anti-takeover laws or regulations enacted under Georgia or
Delaware law ("TAKEOVER LAW") are applicable to Powertel apply to this Agreement
or any of the transactions related thereto.

     SECTION 2.16.  Intellectual Property.  Except as set forth in the Powertel
Filed SEC Documents or in SCHEDULE 2.16, the Intellectual Property Rights
consist solely of items and rights which are: (i) owned by Powertel or the
Powertel Subsidiaries, (ii) in the public domain or (iii) rightfully used by
Powertel or the Powertel Subsidiaries pursuant to a license, and, with respect
to Intellectual Property Rights owned by Powertel or the Powertel Subsidiaries,
Powertel or the Powertel Subsidiaries own the entire right, title and interest
in and to such Intellectual Property Rights free and clear of any Liens.
Powertel and the Powertel Subsidiaries have all rights in the Intellectual
Property Rights necessary to carry out their businesses substantially as
currently conducted except as could not reasonably be expected to have a
Material Adverse Effect on Powertel. The Intellectual Property Rights do not
infringe on any proprietary right of any Person, except to the extent that any
such infringement, individually or in the aggregate, could not reasonably be
expected to have a Material Adverse Effect on Powertel. As of the date of this
Agreement, no claims against Powertel or any Powertel Subsidiary (or to
Powertel's Knowledge, against any other holder of Intellectual Property Rights)
(x) challenging the validity, effectiveness, or ownership by Powertel or the
Powertel Subsidiaries of any of the Intellectual Property Rights, or (y) to the
effect that the Intellectual Property Rights infringe or will infringe on any
intellectual property or other proprietary right of any person have been
asserted or, to Powertel's Knowledge, are threatened by any person nor to
Powertel's Knowledge are there any valid grounds for any bona fide claim of any
such kind. To Powertel's Knowledge, there is no material unauthorized use,
infringement or misappropriation of any

                                      B-18
<PAGE>   390

of the Intellectual Property Rights by any third party, employee or former
employee of Powertel or the Powertel Subsidiaries.

     SECTION 2.17.  Opinion of Financial Advisor.  The Board of Directors of
Powertel has received the oral opinion of Morgan Stanley Dean Witter & Co.
("POWERTEL FINANCIAL ADVISOR"), on the date hereof, to the effect that, as of
the date hereof, the consideration to be received in the Merger by Powertel's
stockholders is fair to Powertel's stockholders from a financial point of view.

     SECTION 2.18.  Brokers.  Except for the Powertel Financial Advisor, the
fees and expenses of which will be paid by Powertel (and are reflected in
agreements with Powertel, a true and correct copy of which has been furnished
to, and accepted by, DT), no broker, investment banker, financial advisor or
other person, is entitled to any broker's, finder's, financial advisor's or
other similar fee or commission in connection with the transactions contemplated
by this Agreement based upon arrangements made by or on behalf of Powertel. In
no event shall the amounts paid or payable by Powertel to the Powertel Financial
Advisor in connection with the transactions contemplated by this Agreement
exceed $28,000,000.

     SECTION 2.19.  Tax Status.  To the Knowledge of Powertel after due
investigation, neither Powertel nor any of its Affiliates has taken any action
or failed to take any action which action or failure would (i) jeopardize the
qualification of the Merger as a reorganization within the meaning of Section
368(a) of the Code or (ii) cause the stockholders of Powertel, other than any
such stockholder that would be a "five-percent transferee shareholder" of DT
(within the meaning of U.S. Treasury Regulations Section 1.367(a)-3(c)(5))
following the Merger, to recognize gain pursuant to Section 367(a) of the Code.
To the Knowledge of Powertel after due investigation, there are no facts or
circumstances relating to Powertel or its Affiliates, including any covenants or
undertakings of Powertel pursuant to this Agreement, that would prevent Morris,
Manning & Martin, LLP from delivering the opinion referred to in Section 6.02(d)
as of the date hereof.

     SECTION 2.20.  Contracts.  Except as set forth in the Powertel Filed SEC
Documents or in SCHEDULE 2.20, and except for this Agreement, the Alternative
Merger Agreement and the agreements referenced hereby and thereby, neither
Powertel nor any of the Powertel Subsidiaries is a party to or bound by (i) any
"material contract" (as such term is defined in Item 601(b)(10) of Regulation
S-K of the SEC) or any agreement, contract or commitment the loss or termination
of which could have a Material Adverse Effect on Powertel; (ii) any
non-competition agreement or any similar agreement or obligation which
materially limits or could materially limit Powertel or any of the Powertel
Subsidiaries from engaging in the business of providing wireless communications
services or from developing wireless communications technology anywhere in the
world or (iii) any management agreement, technical services agreement or other
agreement whereby Powertel or any of the Powertel Subsidiaries is providing or
is required to provide management or technical services to any other Person.
Taken as a whole, the contracts and agreements required to be filed by Powertel
with the SEC together with the contracts and agreements required to be set forth
on SCHEDULE 2.20 are collectively referred to as the "POWERTEL CONTRACTS". With
such exceptions as, individually or in the aggregate, have not had, and could
not be reasonably expected to have, a Material Adverse Effect on Powertel, (x)
each of the Powertel Contracts is valid and in full force and effect (except to
the extent they have previously expired with no residual obligation in
accordance with their terms), and (y) except as set forth in SCHEDULE 2.20,
neither Powertel nor any of the Powertel Subsidiaries has violated any provision
of, or committed or failed to perform any act which, with or without notice,
lapse of time, or both, would constitute a default under the provisions of any
such Powertel Contract. To the knowledge of Powertel, no counterparty to any
such Powertel Contract has violated any provision of, or committed or failed to

to submit any notice, report or other filing with any Governmental or Regulatory
Authority in connection with the execution, delivery or performance of this
Agreement and the Stockholders Agreement, as applicable. Except as set forth in

forms, reports and documents required to be filed with the SEC since January 1,
1999, and has heretofore made available to Powertel, in the form filed with the

Form 20-F for the fiscal year ended December 31, 1999 and (ii) all other reports
or registration statements filed by DT with the SEC since January 1, 1999

required to be stated therein or necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading.

     (b) The financial statements (the "DT FINANCIAL STATEMENTS"), including all
related notes and schedules, contained in the DT SEC Documents (or incorporated
by reference therein) fairly present the consolidated financial position of DT
and its Subsidiaries as at the respective dates thereof and the

consolidated results of operations and cash flows of DT and its Subsidiaries for

actions, suits, proceedings or investigations pending or, to DT's Knowledge,
threatened against DT or any of its Subsidiaries, or any properties or rights of
DT or any of its Subsidiaries, before any Governmental or Regulatory Authority
that would reasonably be expected to result in an adverse judgment or
determination against DT or any of its Subsidiaries, except for those that are
not, individually or in the aggregate, reasonably likely to have a Material
Adverse Effect on DT or prevent or materially delay the consummation of the
Merger except as set forth on SCHEDULE 3.08 hereof.

     SECTION 3.09.  No Violation of Law.  The business of DT and its
Subsidiaries is not being conducted in violation of any Legal Requirements or in
violation of any DT Permits, except for possible violations none of which,

Material Adverse Effect on DT or prevent or materially delay the consummation of
the Merger. Except as disclosed in DT SEC Documents filed prior to the date
hereof and as set forth on SCHEDULE 3.09 hereto, as of the date hereof, no
investigation, review or proceeding by any Governmental or Regulatory Authority
(including, without limitation, any stock exchange or other self-regulatory
body) with respect to DT or its Subsidiaries in relation to any alleged
violation of law or regulation is pending or, to DT's Knowledge, threatened, nor
has any Governmental or Regulatory Authority (including, without limitation, any
stock exchange or other self-regulatory body) indicated in writing an intention
to conduct the same, except for such investigations which, if they resulted in
adverse findings, would not reasonably be expected to have, individually or in
the aggregate, a Material Adverse Effect on DT.

     SECTION 3.10.  Information Provided by DT.  None of the information
supplied or to be supplied by or on behalf of DT for inclusion or incorporation
by reference in the Registration Statement will, at the time the Registration
Statement becomes effective under the Securities Act, contain any untrue

misleading. The Registration Statement (except for information relating solely
to Powertel) will comply as to form in all material respects with the provisions
of the Securities Act and the rules and regulations promulgated thereunder. None
of the information supplied or to be supplied by or on behalf of DT for
inclusion or incorporation by reference in the German Listing Prospectus will,

Subsidiaries.

     SECTION 3.13.  Tax Matters.  Except as set forth on SCHEDULE 3.13 and

Material Adverse Effect on DT:

          (a) All Tax Returns required to be filed by DT or its Subsidiaries on

     appropriate Governmental or Regulatory Authorities and are or will be

          (d) No extension of the statute of limitations on the assessment of

     currently in effect;

          (e) Neither DT nor any of its Subsidiaries has taken any action or

     any such stockholder that would be a "five-percent transferee shareholder"
     of DT (within the meaning of U.S. Treasury Regulations Section

     Section 367(a) of the Code; and

threatened, any action by or before any Governmental or Regulatory Authority to
revoke, suspend, cancel, rescind or modify in any material respect any of the DT
Licenses which action would reasonably be expected to have a Material Adverse
Effect on DT.

     with applicable law or as permitted by Section 4.01(b), provided, further,
     that nothing in this Section 4.01(h) shall restrict the ability of
     Powertel's Board of Directors to take the action contemplated by and to
     comply with the terms of the severance, retention and other arrangements as
     set forth in Annex 5.18 and to adopt appropriate resolutions with respect
     to persons who are officers or directors (including persons who are

     providing wireless communications services or developing wireless
     communications technology anywhere in the world or otherwise from engaging
     in any other business;

     any discretionary contributions to any ERISA Benefit Plan other than as may

     Powertel may enter into derivative contracts as part of their ordinary

     during the period of time beginning on the fifth Business Day prior to the
     Effective Time and extending until and including the Effective Time,

     number of shares of Powertel Stock outstanding on a fully diluted basis; or

          (bb) enter into any contract, agreement, commitment or arrangement to

on behalf of itself and its Subsidiaries that

                                      B-27
<PAGE>   399

they will not, between the date hereof and the Effective Time, directly or
indirectly, do any of the following without the prior written consent of
Powertel:

          (a) except as may be necessary or required for the purpose of using or
     increasing any or all of DT's authorized capital (GENEHMIGTES KAPITAL) or
     necessary for the conduct of its business, amend or propose to amend the
     Memorandum and Articles of Association (SATZUNG) or Management Board
     (VORSTAND) Rules of Procedure (GESCHAFTSORDNUNG) (or other comparable
     organizational document) of DT in any manner that would be adverse to
     Powertel or its stockholders;

          (b) take any action that would reasonably be likely to (i) prevent or
     impede the Merger from qualifying as a reorganization within the meaning of
     Section 368(a) of the Code or (ii) cause the stockholders of Powertel to
     recognize gain pursuant to Section 367(a) of the Code; or

          (c) take any action that would reasonably be likely to (i) materially
     adversely affect the ability of the Parties to obtain any Required
     Regulatory Approval or to consummate the transactions contemplated hereby
     or (ii) materially delay the ability of any of the Parties to obtain any
     Required Regulatory Approval or to consummate the transactions contemplated
     hereby; provided, however, that this Section 4.02(c) shall not preclude any
     acquisitions by DT or any of its Subsidiaries so long as such acquisitions,
     individually or in the aggregate, are not reasonably likely to prevent the
     consummation of the Merger.

     SECTION 4.03.  No Solicitation.  (a) From and after the date hereof until
the earlier of the Effective Time or the termination of this Agreement, Powertel
shall not, nor shall it permit any of the Powertel Subsidiaries to, nor shall
they authorize or instruct any of their respective officers, directors or
employees to, and shall use their reasonable efforts to cause any investment
banker, financial advisor, attorney, accountants or other representatives
retained by them or any of their respective Subsidiaries not to, directly or
indirectly through another person, (i) solicit, initiate or knowingly encourage
(including by way of furnishing information), or knowingly take any other action
designed to facilitate, any Alternative Transaction (as defined below), or (ii)
continue or participate in any discussions or negotiations regarding any
Alternative Transaction; provided, however, that if, at any time prior to the
time that the Powertel Stockholders' Approval is obtained, the Board of
Directors of Powertel receives an unsolicited bona fide proposal and determines
in good faith and after the receipt of advice from outside counsel that
providing information to the Third Party (as defined below), making such
proposal or participating in negotiations or discussions with the Third Party is
reasonably expected to result in a Powertel Superior Proposal (as defined below)
and if Powertel has fully and completely complied with its obligations under
this Section 4.03, Powertel may, subject to giving DT three Business Days'
advance written notice of its intention to do so and obtaining a confidentiality
agreement from the Third Party substantially similar to the Confidentiality
Agreement between Powertel and DT dated as of August 16, 2000 (the
"CONFIDENTIALITY AGREEMENT"), (x) furnish information to such Third Party with
respect to Powertel and the Powertel Subsidiaries and (y) engage in discussions
and negotiations regarding such proposal.

     (b) Powertel will notify DT promptly (but in no event later than 24 hours)
after receipt by Powertel (or any of its advisors) of any Alternative
Transaction, or of any request (other than in the ordinary course of business
and not related to an Alternative Transaction) for non-public information
relating to Powertel or any of the Powertel Subsidiaries or for access to the
properties, books or records of Powertel or any of the Powertel Subsidiaries by
any Person who is known to be considering making, or has made, an Alternative
Transaction. Powertel shall provide such notice orally and in writing and shall
identify the Person making, and the terms and conditions of, any such
Alternative Transaction or request. Powertel shall keep DT fully informed, on a
prompt basis (but in any event no later than 24 hours), of the status and
details of any such Alternative Transaction or request. Powertel shall, and
shall cause the Powertel Subsidiaries and the directors, employees and other
agents of Powertel and the Powertel Subsidiaries to cease immediately and cause
to be terminated all activities, discussions or negotiations, if any, with any
Persons conducted prior to the date hereof with respect to any Alternative
Transaction.

                                      B-28
<PAGE>   400

     (c) Powertel (i) agrees not to release any Third Party from, or waive any
provision of, or fail to enforce, any standstill agreement or similar agreement
to which it is a party related to, or which could affect, an Alternative
Transaction and agrees that DT shall be entitled to enforce Powertel's rights
and remedies under and in connection with such agreements, and (ii) acknowledges
that the provisions of clause (i) are an important and integral part of this
Agreement. Nothing contained in this Section 4.03 or in Section 5.02 shall
prohibit Powertel (x) from complying with Rule 14d-9 or Rule 14e-2(a)
promulgated under the Exchange Act, or (y) from making any disclosure to its
stockholders if, in the good faith judgment of the Board of Directors of
Powertel, after receipt of advice from outside counsel, failure to disclose
would result in a reasonable likelihood that the Board of Directors of Powertel
would breach its duties to Powertel's stockholders under Delaware Law.

     For purposes of this Agreement, "ALTERNATIVE TRANSACTION" means a proposal
or intended proposal, regarding any of (i) a transaction or series of
transactions pursuant to which any Person (or "group" of Persons) other than a
Party and its Subsidiaries (a "THIRD PARTY") acquires or would acquire, directly
or indirectly, "beneficial ownership" (as such terms are defined in or
interpreted for purposes of Rule 13d-3 under the Exchange Act) of more than
twenty percent (20%) of the voting power of the outstanding capital stock of
Powertel or pursuant to a tender offer or exchange offer or otherwise, (ii) any
acquisition or proposed acquisition of, or business combination with Powertel or
any of the Powertel Subsidiaries, as applicable, by a merger or other business
combination (including any so-called "merger-of-equals" and whether or not
Powertel or any of the Powertel Subsidiaries, as the case may be, is the entity
surviving any such merger or business combination) or (iii) any other
transaction pursuant to which any Third Party acquires or would acquire,
directly or indirectly, control of assets (including for this purpose the
outstanding equity securities of the Powertel Subsidiaries and any entity
surviving the merger or business combination including any of them) of Powertel
or any of the Powertel Subsidiaries, as the case may be, for consideration equal
to twenty percent (20%) or more of the fair market value of all of the
outstanding shares of Powertel capital stock on the date of this Agreement;
provided, that for purposes of this Agreement the term "Alternative Transaction"
does not include the proposed acquisition of Powertel by VoiceStream as
contemplated by the Alternative Merger Agreement.

     SECTION 4.04.  Subsequent Financial Statements.  Powertel, prior to the
Effective Time, will timely file with the SEC each Annual Report on Form 10-K,
Quarterly Report on Form 10-Q and Current Report on Form 8-K required to be
filed by it under the Exchange Act and the rules and regulations promulgated
thereunder and will promptly deliver to DT copies of each such report filed with
the SEC. DT will timely file with the SEC each Annual Report on Form 20-F and
Report on Form 6-K required to be filed by it under the Exchange Act and the
rules and regulations promulgated thereunder and will promptly deliver to
Powertel copies of each such report filed with the SEC. As of their respective
dates, none of such reports shall contain any untrue statement of a material
fact or omit to state a material fact required to be stated therein or necessary
to make the statements therein, in light of the circumstances under which they
were made, not misleading. The respective audited financial statements and
unaudited interim financial statements of each of Powertel and DT, as the case
may be, included in such reports will fairly present the financial position of
such Party and its Subsidiaries as at the dates thereof and the results of their
operations and cash flows for the periods then ended in accordance with GAAP
(with a reconciliation to GAAP in accordance with SEC rules in the case of
Powertel) or generally accepted accounting principles in Germany (in the case of
DT) applied on a consistent basis and, subject, in the case of unaudited interim
financial statements, to normal year-end adjustments and any other adjustments
described therein.

     SECTION 4.05.  Control of Operations.  Nothing contained in this Agreement
shall be deemed to give DT, directly or indirectly, the right to "control" or
"direct", as such terms are construed under applicable rules or regulations of
the FCC, Powertel's operations prior to the Effective Time. Prior to the
Effective Time, Powertel shall exercise, consistent with the terms and
conditions of this Agreement, "control" over its respective operations.

     SECTION 4.06.  Alternative Merger Agreement.  Powertel will not modify,
amend or waive in any material respect the provisions of the Alternative Merger
Agreement without DT's prior written consent.

                             ADDITIONAL AGREEMENTS

     SECTION 5.01.  Powertel Proxy Statement; the DT Registration Statement and
the German Listing Prospectus.  (a) Each of DT and Powertel shall cooperate and
promptly prepare and DT shall file with the SEC as soon as practicable the DT
Registration Statement on Form F-4 (or any successor form) (the "FORM F-4")
under the Securities Act with respect to the DT Ordinary Shares and the DT
Depositary Shares issuable and deliverable pursuant to this Agreement. A portion
of the Form F-4 shall serve as a prospectus with respect to the DT Ordinary
Shares and the DT Depositary Shares issuable and deliverable pursuant to the
terms of this Agreement and as Powertel's proxy statement with respect to
Powertel Stockholders' Meeting (the "POWERTEL PROXY STATEMENT"). DT will cause
the Form F-4 to comply as to form in all material respects with the applicable
provisions of the Securities Act and the rules and regulations thereunder, and
Powertel will cause the Powertel Proxy Statement to comply as to form in all
material respects with the applicable provisions of the Exchange Act and the
rules and regulations thereunder. Powertel and DT shall use their reasonable
best efforts to have the Powertel Proxy Statement and the DT Registration
Statement declared effective by the SEC under the Securities Act, and promptly
thereafter shall mail to the holders of record of Powertel Common Shares the
Powertel Proxy Statement; provided, however, that Powertel shall not mail or
otherwise furnish the Powertel Proxy Statement to its stockholders unless and
until:

          (i) it has received oral notice from the SEC that the DT Registration
     Statement is effective under the Securities Act;

          (ii) Powertel shall have received a letter of its independent
     accountants, dated a date within two (2) business days prior to the date of
     the first mailing of the Powertel Proxy Statement, and addressed to
     Powertel, in form reasonably satisfactory to Powertel and customary in
     scope for similar "cold comfort" letters delivered by independent public
     accountants in connection with registration statements on Form F-4 with
     respect to the financial statements of DT included in the Powertel Proxy
     Statement and the DT Registration Statement;

          (iii) DT shall have received a letter of its independent accountants,
     dated a date within two (2) business days prior to the date of the first
     mailing of the Powertel Proxy Statement, and addressed to DT, in form
     reasonably satisfactory to DT and customary in scope for similar "cold
     comfort" letters delivered by independent public accountants in connection
     with registration statements on Form F-4 with respect to the financial
     statements of Powertel included in the Powertel Proxy Statement and the DT
     Registration Statement.

     DT shall take any reasonable action (other than qualifying to do business
in any jurisdiction in which it is now not so qualified) to obtain prior to the
effective date of the Form F-4 all necessary state securities law or "Blue Sky"
permits and approvals or similar foreign approvals required to effect the
transactions contemplated by this Agreement, including the distribution of DT
Depositary Shares and DT Ordinary Shares issued in accordance with the
provisions of this Agreement, and Powertel will provide any reasonably requested
cooperation in connection therewith. DT will advise Powertel of the time when
the Form F-4 has become effective or any supplement or amendment has been filed,
the issuance of any stop order or the suspension of the qualification of the DT
Depositary Shares or DT Ordinary Shares issuable and deliverable in connection
with the Merger for offering or sale in any jurisdiction.

     (b) DT and Powertel will cooperate in (i) the preparation of the Powertel
Proxy Statement and the DT Registration Statement or any amendments and
supplements thereto and in having the DT Registration Statement declared
effective as soon as practicable and (ii) the preparation and filing of the
German Listing Prospectus with the FSE and the auditor's report with the
Commercial Register.

     SECTION 5.02.  Powertel Stockholders' Meeting and Consummation of the
Merger.

     (a) As promptly as practicable after the DT Registration Statement is
declared effective under the Securities Act, Powertel shall duly give notice of,
convene and hold a meeting of its stockholders (the

                                      B-30
<PAGE>   402

"POWERTEL STOCKHOLDERS' MEETING") in accordance with Delaware Law for the
purposes of obtaining the Powertel Stockholder Approval and shall, subject to
the provisions of Section 5.02(b) hereof, through its Board of Directors,
recommend to its stockholders the approval and adoption of this Agreement and
use its reasonable best efforts to obtain the Powertel Stockholder Approval.

     (b) Neither the Board of Directors of Powertel nor any committee thereof
shall (i) except as expressly permitted by this Section 5.02(b), withdraw,
qualify or modify, or propose publicly to withdraw, qualify or modify, in a
manner adverse to DT, the approval or recommendation of such Board of Directors
or such committee of this Agreement, the Merger and the other transactions
contemplated hereby, (ii) approve or recommend, or propose publicly to approve
or recommend, any Alternative Transaction, or (iii) cause Powertel to enter into
any letter of intent, agreement in principle, acquisition agreement or other
similar agreement related to any Alternative Transaction (each, a "POWERTEL
ACQUISITION AGREEMENT"). Notwithstanding the foregoing, in the event that prior
to the time the Powertel Stockholder Approval is obtained, Powertel receives a
Superior Proposal (as defined below), the Board of Directors of Powertel may
(subject to this and the following sentences) inform Powertel stockholders that
it no longer recommends Powertel Stockholder Approval (a "SUBSEQUENT
DETERMINATION"), but only at a time that is after the fifth Business Day
following DT's receipt of written notice advising DT that the Board of Directors
of Powertel has received a Superior Proposal specifying the material terms and
conditions of such Superior Proposal (and including a copy or draft copy thereof
with all accompanying documentation or draft documentation, if in writing),
identifying the Person making such Superior Proposal and stating that it intends
to make a Subsequent Determination. After providing such notice, Powertel shall
provide a reasonable opportunity to DT to make such adjustments in the terms and
conditions of this Agreement as would enable Powertel to proceed with its
recommendation to its stockholders without a Subsequent Determination; provided,
however, that any such adjustment shall be at the discretion of Powertel and DT
at the time. For purposes of this Agreement, a "SUPERIOR PROPOSAL" means any
proposal (on its most recently amended or modified terms, if amended or
modified) made by a Third Party to enter into an Alternative Transaction which
the Board of Directors of Powertel determines in its good faith judgment (based
on, among other things, the advice of a financial advisor of nationally
recognized reputation) to be more favorable to Powertel's stockholders than the
transactions contemplated by this Agreement taking into account all relevant
factors (including whether, in the good faith judgment of the Board of Directors
of Powertel, after obtaining the advice of a financial advisor of nationally
recognized reputation, the Third Party is reasonably able to finance the
transaction, and any changes to this Agreement that may be proposed by DT in
response to such Alternative Transaction). Powertel shall submit this Agreement
to its stockholders at the Powertel Stockholders' Meeting even if the Board of
Directors of Powertel shall have made a Subsequent Determination.

     Powertel shall use its reasonable best efforts to schedule the Powertel
Stockholders' Meeting at the same time as the Powertel Stockholders' Meeting (as
defined in the Alternative Merger Agreement).

     SECTION 5.03.  Notification of Certain Matters.  (a) Each of Powertel and
DT shall give prompt notice to each other of the following:

          (i) the occurrence or nonoccurrence of any event whose occurrence or
     nonoccurrence would be likely to cause either (i) any representation or
     warranty contained in this Agreement of such Party to be untrue, inaccurate
     or incomplete in any material respect at any time from the date hereof to
     the Effective Time if such failure to be true, accurate or complete would
     cause the condition set forth in Section 6.02(a) or 6.03(a) not to be
     satisfied, in which case the Party required to give prompt notice thereof
     shall promptly update and deliver to the other Party any Schedules hereto
     which require an update to remain true, accurate and correct or (ii)
     directly or indirectly, any Material Adverse Effect on such Party;

          (ii) any material failure of such Party, or any officer, director,
     employee or agent of any thereof, to comply with or satisfy any covenant or
     agreement to be complied with or satisfied by it hereunder (if such failure
     would cause the condition set forth in Section 6.02(b) or 6.03(b) not to be
     satisfied); and

                                      B-31
<PAGE>   403

          (iii) any facts relating to such Party which would make it necessary
     or advisable to amend the Powertel Proxy Statement or the DT Registration
     Statement in order to make the statements therein not misleading or to
     comply with applicable law; provided, however, that the delivery of any
     notice pursuant to this Section 5.03 shall not limit or otherwise affect
     the remedies available hereunder to the Parties receiving such notice.

          (iv) Promptly upon receipt by Powertel from any Powertel stockholder
     who is a party to the Powertel Stockholder Agreements of a proxy card sent
     to the Powertel stockholders with the Powertel Proxy Statement and in
     accordance with Section 5 of the Stockholders Agreement, but in no event
     later than the second Business Day following such receipt or, if such
     receipt is on or after the fifth Business Day prior to the Closing, then on
     the date of such receipt, Powertel shall notify DT orally of its receipt
     and provide DT with copy of such proxy card.

     (b) DT shall promptly provide to Powertel a copy of any written notice
given by DT to VoiceStream or received by DT from VoiceStream of the termination
of the VoiceStream Merger Agreement.

     SECTION 5.04.  Access to Information.  Upon reasonable notice and subject
to restrictions contained in the Confidentiality Agreement and other
confidentiality agreements to which Powertel is subject, (a) Powertel shall, and
shall cause each Powertel Subsidiary to, afford to DT and to the officers,
employees, accountants, counsel and other representatives of DT all reasonable
access, during normal business hours during the period prior to the Effective
Time, to all their respective lenders, agents and other representatives,
properties, assets, books, contracts, commitments and records and, during such
period, Powertel shall (and shall cause each Powertel Subsidiary to) furnish
promptly to DT all information concerning its business, properties and personnel
as DT may reasonably request, including a copy of each report, schedule,
registration statement and other document filed or received by it during such
period pursuant to the requirements of the federal or state securities laws or
the federal Tax laws and (b) DT shall, and shall cause each DT Subsidiary to,
afford to Powertel and to the officers, employees, accountants, counsel and
other representatives of Powertel all reasonable access, during normal business
hours during the period prior to the Effective Time, to all their respective
properties, assets, books, contracts, commitments and records and, during such
period, DT shall (and shall cause each DT Subsidiary to) furnish promptly to
Powertel all information concerning its business, properties and personnel as
Powertel may reasonably request, including a copy of each report, schedule,
registration statement and other document filed or received by it during such
period pursuant to the requirements of the federal or state securities laws.

     SECTION 5.05.  Public Announcements.  DT and Powertel will consult with
each other before issuing any press release with respect to the transactions
contemplated by this Agreement and shall not issue any such press release prior
to such consultation, except as may be required by applicable law, fiduciary
duties or by obligations pursuant to any listing agreement with any national
securities exchange. The parties will cooperate in preparing a joint press
release announcing the execution of this Agreement.

     SECTION 5.06.  Cooperation. (a) Upon the terms and subject to the
conditions hereof, each of Powertel and DT agrees, and agrees to cooperate with
each other, (i) to use reasonable best efforts to consummate and make effective,
in the most expeditious manner practicable, the Merger and the transactions
contemplated by this Agreement, (ii) to obtain in a timely manner all necessary
Permits or waivers from, approvals or consents of, or declarations,
registrations or filings with, and all expirations of waiting periods imposed
by, any Governmental or Regulatory Authority which are necessary for the
consummation of the transactions contemplated hereby, (iii) to promptly (A)
prepare and file a Premerger Notification in accordance with the HSR Act, comply
with any requests for additional information, and obtain termination of the
waiting period thereunder as promptly as practicable, (B) prepare and file all
required notifications, if any, under Council Regulation (EEC) No. 4064/89, and
obtain the approval of the Council of the European Union to the transactions
contemplated by this Agreement, if required, and (C) file a notice pursuant to
Section 721 of Exon-Florio, and (iv) to take all actions within its control
necessary to obtain any Required Regulatory Approvals necessary to consummate
the transactions contemplated hereby; provided, however, that neither DT nor any
of its Subsidiaries shall

                                      B-32
<PAGE>   404

be required, nor, without the consent of DT, shall Powertel or its Subsidiaries
be permitted, to divest or hold separate or otherwise take or commit to take any
action that limits its freedom of action with respect to Powertel, DT,
VoiceStream or any of their Subsidiaries or any material portion of the assets
of Powertel, DT, VoiceStream or any of their Subsidiaries or any of the
business, product lines, or assets of Powertel, DT, VoiceStream or any of their
Subsidiaries.

     (b) Each of Powertel and DT agrees to cooperate with each other (i) to
respond to inquiries from, and to make presentations to, Governmental or
Regulatory Authorities and (ii) to promptly inform the others of any material
oral or written communication received by such Party from, or given by such
Party to, any Governmental or Regulatory Authority, and of any material
communication received or given in connection with any proceeding by a private
Party, in each case regarding the transactions between DT and Powertel
contemplated by this Agreement. Powertel and DT agree to consult with each other
in advance of any meeting or conference with, or of making any filing or other
written submission to, any such Governmental or Regulatory Authority, and to the
extent permitted by the applicable Governmental or Regulatory Authority, give
the others the opportunity to attend and participate in such meetings and
conferences, or to review and approve any such filing or other written
submission, in each case regarding the transactions between DT and Powertel
contemplated by this Agreement. Powertel shall promptly provide to DT, upon
request, and DT shall promptly provide to Powertel, upon request, copies of all
written communications referenced in Section 5.06(b)(i) above and all filings
made by DT or Powertel, as the case may be, with any Governmental or Regulatory
Authority in connection with this Agreement and the transactions contemplated
hereby and written correspondence from any Governmental or Regulatory Authority
that relates to the transactions contemplated hereby (excluding any exhibits,
schedules and any confidential information contained therein).

     (c) Each of Powertel and DT shall cooperate with each other to eliminate or
reduce to the extent possible any illegality, forfeiture or loss on the part of
DT, Powertel or their respective Subsidiaries that may result from the
consummation of the transactions contemplated hereby.

     (d) Each of Powertel and DT hereby agrees to cooperate with the other
party, and to cause its officers, directors and independent accountants to
cooperate with the other party, to do or cause to be done all things reasonably
requested by the other party (including, without limitation, providing such
information as may reasonably be requested to permit pro forma financial
statements after giving effect to the Merger to be produced) in order to
facilitate any financing, acquisition or capital markets transaction or
registration to be entered into or made by either Party after the date hereof.

     (e) Powertel hereby agrees to use reasonable best efforts, in consultation
with DT, to obtain all waivers and consents that may be required from any
parties to any Powertel Contract, including, without limitation, from lenders
and other financing sources of Powertel and its Subsidiaries, in connection with
this Agreement, the Powertel Stockholder Agreements and the transactions
contemplated hereby and thereby.

     (f) Powertel hereby agrees, from the date hereof until the Closing, to take
any and all actions that are required to be taken prior to the Effective Time
pursuant to any Powertel Contract or other agreement, including, without
limitation, any debt instruments, including credit agreements and indentures, to
which Powertel or any of its Significant Subsidiaries is a party and to make any
offer to purchase any securities required to be made, as a result of the
execution and delivery of this Agreement and the Powertel Stockholder
Agreements.

     (g) DT shall cause Merger Sub to approve, and shall vote all securities and
give all approvals necessary for Merger Sub to approve, the Merger.

     (h) Notwithstanding anything to the contrary contained in this Agreement,
in connection with any filing or submission required or action to be taken by
DT, Powertel or any of its respective Subsidiaries to consummate the Merger or
the other transactions contemplated in this Agreement, Powertel shall not,
without DT's prior written consent, commit to any divestiture of assets of
businesses of Powertel and its

                                      B-33
<PAGE>   405

Subsidiaries if such divested assets and/or businesses are material to the
assets or profitability of Powertel and its Subsidiaries taken as a whole.

     SECTION 5.07.  Indemnification, Directors' and Officers' Insurance.  (a) DT
shall, or shall cause the Surviving Corporation to, continue to provide, fulfill
and honor all rights to indemnification or exculpation existing in favor of a
director, officer, employee or agent (an "INDEMNIFIED PERSON") of Powertel or
any of the Powertel Subsidiaries (including rights relating to advancement of
expenses and indemnification rights to which such persons are entitled because
they are serving as a director, officer, agent or employee of another entity at
the request of Powertel or any of the Powertel Subsidiaries), as provided in the
Restated Certificate of Incorporation of Powertel, the Restated By-laws of
Powertel or any indemnification agreement, in each case, as in effect on the
date of this Agreement, and relating to actions or events through the Effective
Time, and such rights to indemnification shall survive the Merger and shall
continue in full force and effect, without any amendment thereto; provided,
however, that neither DT nor the Surviving Corporation shall be required to
indemnify any Indemnified Person in connection with any proceeding (or portion
thereof) to the extent involving any claim initiated by such Indemnified Person
unless the initiation of such proceeding (or portion thereof) was authorized by
the Board of Directors of Powertel or unless such proceeding is brought by an
Indemnified Person to enforce rights under this Section 5.07; provided further
that any determination required to be made with respect to whether an
Indemnified Person's conduct complies with the standards set forth under the
Delaware Law, the Restated Certificate of Incorporation of Powertel, the
Restated By-laws of Powertel or any such agreement, as the case may be, shall be
made by independent legal counsel selected by DT and reasonably acceptable to
such Indemnified Person; provided further that DT and the Surviving Corporation
will cooperate and use all reasonable efforts to assist in the vigorous defense
of any such matter; and provided further that nothing in this Section 5.07 shall
impair any rights of any Indemnified Person. Without limiting the generality of
the preceding sentence, in the event that any Indemnified Person becomes
involved in any actual or threatened action, suit, claim, proceeding or
investigation after the Effective Time relating to actions prior to the
Effective Time, DT shall, or shall cause the Surviving Corporation to, promptly
advance to such Indemnified Person his or her legal and other expenses
(including the cost of any investigation and preparation incurred in connection
therewith), subject to the providing by such Indemnified Person, to the extent
required by law, of an undertaking to reimburse all amounts so advanced in the
event of a non-appealable determination of a court of competent jurisdiction
that such Indemnified Person is not entitled thereto.

     (b) Subject to the prior written approval by DT, which shall not be
unreasonably withheld, prior to the Effective Time, Powertel shall have the
right to obtain and pay for in full a "tail" coverage directors' and officers'
liability insurance policy ("D&O INSURANCE") covering a period of six years
after the Effective Time and providing coverage in amounts and on terms
consistent with Powertel's existing D&O Insurance. In the event the Surviving
Corporation does not obtain such insurance, DT shall cause the Surviving
Corporation to continue to provide D&O Insurance relating to actions or events
through the Effective Time, for a period of six years after the Effective Time;
provided, that the Surviving Corporation may substitute therefor policies of
substantially similar coverage and amounts containing terms no less advantageous
to such former directors or officers; provided further that if the existing D&O
Insurance expires or is cancelled during such period, DT or the Surviving
Corporation shall make reasonable commercial efforts to obtain substantially
similar D&O Insurance; and provided further that the Surviving Corporation shall
not be required to expend, in order to maintain or procure an annual D&O
Insurance policy, an amount in excess of 250% of the last annual premium paid
prior to the date hereof, but in such case shall purchase as much coverage as
possible for such amount.

     (c) In the event DT or the Surviving Corporation or any of their respective
successors or assigns (i) consolidates with or merges into any other person and
shall not be the continuing or surviving corporation or entity of such
consolidation or merger or (ii) transfers all or substantially all of its
properties and assets to any person in a single transaction or a series of
related transactions, then, and in each such case, DT will make or cause to be
made proper provision so that the successors and assigns of

                                      B-34
<PAGE>   406

DT or the Surviving Corporation, as the case may be, assume the indemnification
obligations described herein for the benefit of the Indemnified Parties.

     (d) The provisions of this Section 5.07 are intended to be for the benefit
of, and shall be enforceable by, each Indemnified Person, his or her heirs and
his or her personal representatives and shall survive the Merger and be binding
upon the successors and assigns of DT, Powertel and the Surviving Corporation.

     SECTION 5.08.  Stock Exchange Listings/Establishment of DT Depositary
Shares.  DT will take all steps necessary for the listing and authorization for
listing on the FSE and the NYSE (subject to official notice of issuance) of the
DT Ordinary Shares and the DT Depositary Shares, respectively, to be issued
pursuant to the Merger.

     SECTION 5.09.  No Shelf Registration.  DT shall not be required to amend or
maintain the effectiveness of the Registration Statement for the purpose of
permitting resale of the shares of DT received pursuant hereto by the Persons
who may be deemed to be "affiliates" of Powertel within the meaning of Rule 145
promulgated under the Securities Act. The DT Ordinary Shares issuable upon
exercise of options pursuant to Section 1.05 hereof shall be registered under
the Securities Act and such registration shall be effective at the time of
issuance.

     SECTION 5.10.  Affiliates.  Powertel (i) shall deliver to DT not later than
the 30th day after the date of this Agreement a list of all persons who are, as
of the date hereof, its Affiliates for purposes of Rule 145 under the Securities
Act and (ii) shall use its reasonable best efforts to cause each person who is
identified as its "affiliate" on SCHEDULE 5.10 to deliver to DT as promptly as
practicable but in no event later than the Closing Date, a signed agreement
substantially in the form of Exhibit A. Powertel shall notify DT from time to
time of any other persons who then are such an "affiliate" of Powertel and use
its reasonable best efforts to cause each additional person who is identified as
such an "affiliate" to execute a signed agreement as set forth in this Section
5.10.

     SECTION 5.11.  Tax-Free Merger.  Each of the Parties will use its
reasonable best efforts, and each agrees to cooperate with the other Parties and
provide one another with such documentation, information and materials as may be
reasonably necessary, proper or advisable to (i) cause the Merger to qualify as
a reorganization within the meaning of Section 368(a) of the Code and (ii) avoid
gain recognition to the stockholders of Powertel pursuant to Section 367(a) of
the Code.

     SECTION 5.12.  Reasonable Best Efforts.  Each of Powertel and DT shall use
its reasonable best efforts to obtain the opinions referred to in Section
6.02(d), Section 6.02(e), 6.03(d) and 6.03(e) and the delivery of the
Representation Letters in the forms set forth in Exhibits B and C.

     SECTION 5.13.  Takeover Laws.  Subject to Section 5.02, no Party shall take
any action that would cause the transactions contemplated by this Agreement or
the Stockholders Agreement to be subject to requirements imposed by any Takeover
Laws (including any such laws or regulations applicable to DT under German Legal
Requirements or the Legal Requirements of the FSE) and each of them shall take
all necessary steps within its control to exempt (or ensure the continued
exemption of), or minimize the effect on, the transactions contemplated by this
Agreement and the Stockholders Agreement from, or if necessary challenge the
validity or applicability of, any applicable Takeover Law, as now or hereafter
in effect, including, without limitation, Section 203 of the Delaware Law or any
other Takeover Laws that purport to apply to this Agreement or the Stockholders
Agreement or the transactions contemplated hereby or thereby.

     SECTION 5.14.  Certain Litigation.  Powertel agrees that it shall not
settle any litigation commenced after the date hereof against Powertel or any of
its directors by any stockholder of Powertel relating to the Merger, this
Agreement, the Alternative Merger Agreement or the Stockholders Agreement
without the prior written consent of DT, which consent shall not be unreasonably
withheld or delayed.

     SECTION 5.15.  Senior Discount Notes and Senior Notes.  Within 30 days
following the Effective Time, DT shall cause the Surviving Corporation to
commence an offer to purchase all of the Senior Discount Notes and Senior Notes
(collectively, the "NOTES") pursuant to the terms of the February 1996

                                      B-35
<PAGE>   407

Indenture, April 1996 Indenture and June 1997 Indenture, as applicable
(collectively, the "POWERTEL INDENTURES"). Any investment banking firm engaged
in connection with such acquisition shall be selected by DT. DT shall bear the
fees, costs and expenses of acquiring the Notes.

     SECTION 5.16.  Employee Benefits.  (a) As of the Effective Time, Powertel
will have terminated all Powertel Benefit Plans except for those Powertel
Benefit Plans that DT requests not be terminated and those Powertel Benefit
Plans described in Annex 5.18. DT shall take all necessary action so that, after
the Effective Time, any current or former employee of Powertel who is eligible
to participate in a Powertel Benefit Plan as of the Effective Time shall either
be eligible to continue his or her participation in such Powertel Benefit Plan
or participate in a corresponding employee benefit plan maintained by DT or any
of its Subsidiaries, subject to the terms of such corresponding plan. DT shall
have the sole discretion to determine which current or former employees of
Powertel will continue participation in a Powertel Benefit Plan after the
Effective Time and which will commence participation in a corresponding employee
benefit plan maintained by DT or any of its Subsidiaries after the Effective
Time and, with respect to current or former employees who transfer participation
to such a corresponding plan, when such transfer will occur. DT need not treat
all current and former employees of Powertel (including those who are similarly
situated) in the same manner with respect to which plans they participate in and
when, if at all, they transfer participation from a Powertel Benefit Plan to a
corresponding employee benefit plan maintained by DT or any of its Subsidiaries.
For example, DT may decide to have a current or former employee of Powertel
continue participation after the Effective Time in certain Powertel Benefit
Plans that have not been terminated, and with respect to other benefits
transition his or her participation on or shortly after the Effective Time to a
corresponding employee benefit plan maintained by DT or one of its Subsidiaries.
DT may take such actions (or cause its Subsidiaries or the Surviving Corporation
to take such actions) as are necessary or advisable to accomplish the foregoing,
including, without limitation, amending the eligibility provisions of plans of
DT, any of its Subsidiaries or the Surviving Corporation (including, without
limitation, Powertel Benefit Plans that are not terminated on or before the
Effective Time). Within 5 days of the date hereof, Powertel shall deliver a true
and complete list of each director, officer and employee of Powertel and its
Subsidiaries holding options under any Powertel Benefit Plan as of August 18,
2000, and the dollar or share amounts thereof.

     (b) Except as otherwise provided in this Section, nothing in this Agreement
shall be interpreted as limiting the power of the Surviving Corporation to amend
or terminate any particular Powertel Benefit Plan or any other particular
employee benefit plan, program, agreement or policy or as requiring the
Surviving Corporation or DT to offer to continue (other than as required by its
terms) any written employment contract or to continue the employment of any
specific person; provided, however, (1) that no such termination or amendment
may take away benefits or any other payments already accrued as of the time of
such termination or amendment without the consent of such person, except as
allowed by law, and (2) that nothing in this Section 5.01 shall be interpreted
as limiting or modifying any requirement in Section 5.18 or the provisions of
Annex 5.18.

     (c) DT shall, or shall cause the Surviving Corporation to, (i) waive all
limitations, to the extent allowable under applicable law, as to pre-existing
conditions, exclusions and waiting periods with respect to participation and
coverage requirements applicable to the current and former employees of Powertel
and its Subsidiaries under any welfare or fringe benefit plan in which such
employees and former employees may be eligible to participate after the
Effective Time (other than a Powertel Benefit Plan that is not terminated on or
before the Effective Time), other than limitations or waiting periods that are
in effect with respect to such employees and that have not been satisfied under
the corresponding welfare or fringe benefit plan maintained by Powertel for such
current and former employees prior to the Effective Time, (ii) provide each
current and former employee with credit under any welfare plans in which such
employee or former employee becomes eligible to participate after the Effective
Time for any co-payments and deductibles paid by such current or former employee
for the then current plan year under the corresponding welfare plans maintained
by Powertel prior to the Effective Time, and (iii) provide (to the extent
allowed by law and Treasury regulations applicable to tax-qualified plans) each
current and former employee with full credit for purposes of eligibility,
vesting, and determination of the level of benefits

                                      B-36
<PAGE>   408

under any employee benefit plans, policies, practices or arrangements maintained
by DT or any Subsidiary of DT for such current or former employee's service with
Powertel or any Powertel Subsidiary to the same extent recognized by Powertel
immediately prior to the Effective Time.

     (d) Neither Powertel nor any Affiliate thereof shall, from the date hereof
until the Effective Time, without the prior express written consent of DT, make
any contribution, sale or other transfer of Powertel Stock or any other
"employer security" (as such term is defined in Section 407 of ERISA), whether
to satisfy a required obligation, to reimburse for expenses incurred, or
otherwise, to any Powertel Benefit Plan or to the Powertel stock fund (or any
other fund) under the Powertel 401(k) Profit Sharing Plan. Moreover, Powertel
shall, promptly after the date hereof, amend the Powertel 401(k) Profit Sharing
Plan (as amended and restated effective as of January 1, 1998, and further
amended August 23, 1999), (a) to require that all contributions, from whatever
source, be made in the form of cash and (b) to preclude the use of any present
or future Powertel 401(k) Profit Sharing Plan assets to purchase from Powertel,
or any Affiliate thereof, shares of Powertel Stock or other "employer
securities" (as such term is defined in Section 407 of ERISA); it being
understood, however, that such amendment need not preclude the Powertel 401(k)
Profit Sharing Plan from purchasing Powertel Stock on the open market from any
person or entity, other than Powertel or an Affiliate thereof, nor require that
shares of Powertel Stock and units in the Powertel stock fund presently under
the Powertel 401(k) Profit Sharing Plan be sold or otherwise liquidated.

     SECTION 5.17.  Termination of Agreements with Stockholders.  Powertel
agrees to the termination of the agreements referred to in Section 7 of the
Powertel Stockholder Agreements.

     SECTION 5.18.  Plans and Programs to be Implemented.  After the execution
of this Agreement, Powertel and/or its subsidiaries shall adopt and implement
the plans and arrangements described in Annex 5.18 with each such plan or
arrangement being approved by VoiceStream and DT prior to such adoption or
implementation. Each such plan or arrangement shall be designed to become
effective as of the Effective Time (contingent upon the occurrence of the
transactions contemplated by this Agreement) and remain effective without
modification of the terms and provisions of such plan or arrangement until the
termination date noted for each respective plan or arrangement in Annex 5.18.
After the execution of this Agreement, Powertel and/or its subsidiaries shall
take such actions as are required, necessary or appropriate to implement the
provisions of Annex 5.18 and this Section 5.18, notwithstanding any provisions
of this Agreement to the contrary, and no such actions shall be deemed to be a
breach of any other provision of this Agreement.

     SECTION 5.19.  Voting Agreement and Transfer Restrictions.  (a) If and when
DT becomes a record or beneficial owner of any Shares, DT agrees:

          (i) that, from the date hereof until the later of January 1, 2001 and
     the date of the VoiceStream Stockholders' Meeting, without Powertel's prior
     written consent, it will not Transfer or agree to Transfer any Shares,
     Additional Shares, Rights or Additional Rights that it owns of record or
     beneficially, except (A) pursuant to the VoiceStream Merger Agreement, (B)
     Transfers to any Affiliate of DT who agrees in writing to be bound by the
     terms of this Section 5.19 or (C) Transfers which occur by operation of law
     if the transferee remains or agrees in writing to remain bound by the terms
     of this Section 5.19; provided, however, that this Section 5.19(a)(i) shall
     cease to be of any force or effect immediately upon termination of the
     Alternative Merger Agreement; and

          (ii) irrevocably and unconditionally to vote or cause to be voted or
     provide consent with respect to, all Shares and Additional Shares, if any,
     that it owns of record or beneficially as of the record date for the
     VoiceStream Stockholders' Meeting at the VoiceStream Stockholders' Meeting
     and at any other annual or special meeting of stockholders of VoiceStream
     or action by written consent where such matters arise in favor of the
     "Merger" contemplated by the Alternative Merger Agreement and, if required,
     the other transactions referenced in the Alternative Merger Agreement.

          (iii) (a) to complete and send the proxy card received by it with the
     Joint Proxy Statement, so that such proxy card is received by VoiceStream,
     as prescribed by the Joint Proxy Statement, not

                                      B-37
<PAGE>   409

     later than the fifth Business Day preceding the day of the VoiceStream
     Stockholders' Meeting, (b) to vote, by completing such proxy card but not
     otherwise, all the Shares it owns of record or beneficially as of the
     record date for the VoiceStream Stockholders' Meeting in favor of the
     "Merger" contemplated in the Alternative Merger Agreement and, if required,
     the other transactions referenced in the Alternative Merger Agreement and
     (c) not to revoke any such proxy.

     (b) The provisions of Section 5.19(a)(i) shall terminate at the earlier of
the date indicated therein and the date of termination of the Alternative Merger
Agreement. Sections 5.19(a)(ii) and 5.19(a)(iii) shall terminate on the earlier
of the termination of the Alternative Merger Agreement and the VoiceStream
Stockholders' Meeting.

     (c) From and after the date that this Agreement terminates in accordance
with Article 7 hereof, DT agrees to abide by the provisions of the second, third
and fourth sentences of Section 6 of the VoiceStream Stockholders' Agreements as
if DT were a "Stockholder" named therein, provided that the First Amended and
Restated Voting Agreement dated July 23, 2000 takes effect as to DT in
accordance with its terms, and, provided, further, that, notwithstanding
anything to the contrary contained herein, nothing contained in this Section
5.19(c) shall require DT to take any action that adversely affects its rights
under the "DT Financing Agreements" (as defined in the VoiceStream Merger
Agreement) or that might result in DT's designees on the VoiceStream Board of
Directors in accordance with the DT Financing Agreements to represent less than
10% of the total number of members of the VoiceStream Board of Directors.

     (d) For purposes of Section 5.19 only, the words "beneficially owns" or
similar expressions of ownership and capitalized terms used but not otherwise
defined in this Agreement shall have the meanings set forth in, or determined in
accordance with, the VoiceStream Stockholder Agreements as if DT were a
"Stockholder" thereunder.

     SECTION 5.20.  Powertel Warrants.  After consultation with each other, DT
and Powertel shall use reasonable efforts to take such actions as they may deem
to be appropriate to attempt to cause the outstanding Powertel Warrants to be
exercised in full prior to the Effective Time, including by reducing the
exercise price of the Powertel Warrants to the extent agreed to by DT and
Powertel and in accordance with the provisions of the Powertel Warrant
Agreement.

                                   ARTICLE 6

                               CLOSING CONDITIONS

     SECTION 6.01.  Conditions to Each Party's Obligation to Effect the

          (a) Stockholder Approval.  The Powertel Stockholder Approval shall
     have been obtained.

          (b) Legality.  No federal, state or foreign statute, rule, regulation,
     executive order, decree, temporary restraining order or injunction shall
     have been enacted, entered, promulgated or enforced by any Governmental or
     Regulatory Authority which is in effect and has the effect of making the
     Merger illegal or otherwise prohibiting the consummation of the Merger or
     which could reasonably be expected to have a Material Adverse Effect on
     Powertel.

          (c) Competition Law Approvals.  Any waiting period applicable to the
     consummation of the Merger under the HSR Act shall have expired or been
     terminated; to the extent required, the Commission of the European Union

                                      B-38
<PAGE>   410

          (d) Registration Statement Effective.  The DT Registration Statement
     shall have become effective prior to the mailing by Powertel of the
     Powertel Proxy Statement to its stockholders, no stop order suspending the
     effectiveness of the DT Registration Statement or the Powertel Proxy
     Statement shall then be in effect, and no proceedings for that purpose
     shall then be threatened by the SEC or shall have been initiated by the SEC
     and not concluded or withdrawn.

          (e) Stock Exchange Listings.  All steps necessary for the listing of
     the DT Ordinary Shares to be issued pursuant to the Merger on the FSE shall
     have been taken and the DT Depositary Shares to be issued pursuant to the
     Merger shall have been authorized for listing on the NYSE, subject to
     official notice of issuance.

          (f) The VoiceStream Merger.  The VoiceStream Merger shall have been
     consummated.

     SECTION 6.02.  Conditions to the Obligations of Powertel.  The obligations
of Powertel to consummate the Merger are also subject to the fulfillment, or
written waiver by Powertel, prior to the Effective Time, of each of the
following conditions:

          (a) Representations and Warranties.  The representation and warranty
     of DT set forth in Section 3.07(a) of this Agreement shall have been true
     and correct on the date hereof and on and as of the Closing Date as though
     made on the Closing Date; and the other representations and warranties of
     DT and Merger Sub set forth in this Agreement shall have been true and
     correct on the date hereof (or, in the case of matters relating to Merger
     Sub, as of September 28, 2000) and on and as of the Closing Date as though
     made on the Closing Date (except to the extent that any representation or
     warranty expressly speaks as of an earlier date, in which case it shall be
     true and correct as of such date) except (i) for changes permitted under
     Section 4.02 or otherwise contemplated by this Agreement and (ii) for such
     failures to be true and correct which in the aggregate would not reasonably
     be expected to result in a Material Adverse Effect on DT.

          (b) Agreements and Covenants.  DT shall have performed or complied
     with all agreements and covenants required by this Agreement to be
     performed or complied with by it on or before the Effective Time; provided,
     however, that for purposes of this Section 6.02(b) only, such agreements
     and covenants shall be deemed to have been complied with unless the failure
     or failures of such agreements and covenants to have been complied with,
     individually or in the aggregate, results or would reasonably be expected
     to result in a Material Adverse Effect on DT.

          (c) Certificates.  Powertel shall have received a certificate of an
     executive officer of DT (and, to the extent such matters relate to Merger
     Sub, of an executive officer of Merger Sub) to the effect set forth in
     subparagraphs (a) and (b) above.

          (d) Tax Opinion.  Powertel shall have received an opinion of Morris,
     Manning & Martin, LLP in a form and substance reasonably satisfactory to
     Powertel, dated as of the Closing Date, substantially to the effect that,
     on the basis of the facts, representations and assumptions set forth or
     referred to in such opinion, for U.S. federal income tax purposes, the
     Merger (i) will qualify as a reorganization within the meaning of Section
     368(a) of the Code and (ii) each transfer of property to DT by a
     stockholder of Powertel pursuant to the Merger will not be subject to
     Section 367(a)(1) of the Code. In rendering such opinion, Morris, Manning &
     Martin, LLP may require and shall be entitled to rely upon customary
     representations of Powertel and DT, including representations substantially
     in the form of Exhibits B and C, respectively and, if reasonably requested,
     customary tax certificates of Powertel Principal Shareholders. The opinion
     set forth in clause (ii) may assume that any stockholder who is a
     "five-percent transferee shareholder" with respect to DT within the meaning
     of U.S. Treasury Regulations Section 1.367(a)-3(c)(5)(ii) will file the
     agreement described in U.S. Treasury Regulations Section

          (f) Governmental Approvals.  All necessary consents or authorizations
     from any Governmental or Regulatory Authority which may be required in
     connection with the transactions contemplated hereby, shall have been
     received, unless the failure to receive any such consent or authorization
     would not have a Material Adverse Effect on DT or the transactions
     contemplated by this Agreement, and such consents or authorizations shall
     not contain any conditions which would reasonably be expected to have a
     Material Adverse Effect on DT or the transactions contemplated by this
     Agreement. With respect to any FCC consents or authorizations,
     effectiveness of necessary FCC approvals shall be sufficient to satisfy
     this condition, and Powertel's obligation to effect the Merger shall not be
     subject to the condition that any FCC consents or authorizations have
     become Final Orders.

     Notwithstanding anything contained to the contrary in Section 6.02(a) or
anywhere else in this Agreement, DT may enter into any Subsequent Transaction,
and no changes of any representation or warranty of DT contained in this
Agreement as a result of any Subsequent Transaction shall result in a failure of
the conditions set forth in Section 6.02(a).

     SECTION 6.03.  Conditions to the Obligations of DT.  The obligations of DT
to consummate the Merger are also subject to the fulfillment or written waiver
by DT, prior to the Effective Time, of each of the following conditions:

          (a) Representations and Warranties.  The representation and warranty
     of Powertel set forth in Section 2.07(i) of this Agreement shall have been
     true and correct on the date hereof and on and as of the Closing Date as
     though made on the Closing Date; and the other representations and
     warranties of Powertel set forth in this Agreement shall have been true and
     correct on the date hereof and on and as of the Closing Date as though made
     on the Closing Date (except to the extent that any representation or
     warranty expressly speaks as of an earlier date, in which case it shall be
     true and correct as of such date) except (i) for changes permitted under
     Section 4.01 hereof or otherwise contemplated by this Agreement and (ii)
     for such failures to be true and correct which in the aggregate would not
     reasonably be expected to result in a Material Adverse Effect on Powertel
     or DT or the transactions contemplated by this Agreement.

          (b) Agreements and Covenants.  Powertel shall have performed or
     complied with all agreements and covenants required by this Agreement to be
     performed or complied with by it on or before the Effective Time; provided,
     however, that for purposes of this Section 6.03(b) only, such agreements
     and covenants shall be deemed to have been complied with unless the failure
     or failures of such agreements and covenants to have been complied with
     individually or in the aggregate, results or would reasonably be expected
     to result in a Material Adverse Effect on Powertel or DT or the
     transactions contemplated by this Agreement.

          (c) Certificates.  DT shall have received a certificate of an
     executive officer of Powertel to the effect set forth in subparagraphs (a)
     and (b) above.

          (d) Tax Opinion.  DT shall have received an opinion of Cleary,
     Gottlieb, Steen & Hamilton, in form and substance reasonably satisfactory
     to DT, dated as of the Closing Date, substantially to the effect that, on
     the basis of facts, representations and assumptions set forth or referred
     to in such opinion, for U.S. federal income tax purposes, the Merger will
     (i) qualify as a reorganization within the meaning of Section 368(a) of the
     Code and (ii) each transfer of property to DT by a stockholder of Powertel
     pursuant to the Merger will not be subject to Section 367(a)(1) of the
     Code. In rendering such opinion, Cleary, Gottlieb, Steen & Hamilton may
     require and shall be entitled to rely upon customary representations of
     Powertel and DT including representations substantially in the form of
     Exhibits B and C, respectively. The opinion set forth in clause (ii) may
     assume that any stockholder who is a "five-percent transferee shareholder"
     with respect to DT within the meaning of U.S. Treasury Regulations
     1.367(a)-3(c)(5)(ii) will file the agreement described in U.S. Treasury
     Regulations Section 1.367(a)-3(c)(1)(iii)(B).

          (e) FCC Opinion.  DT shall have received an opinion of FCC counsel of
     Powertel, dated the Effective Time, substantially in the form attached
     hereto as Exhibit D.

     consent or approval of each person whose consent or approval shall be
     required in connection with the transactions contemplated hereby under any
     indenture, mortgage, evidence of indebtedness, lease or other agreement or
     instrument to which Powertel or any of the Powertel Subsidiaries is a
     party, except where the failure to obtain the same would not reasonably be
     expected, individually or in the aggregate, to have a Material Adverse
     Effect on Powertel or DT or upon the transactions contemplated by this
     Agreement.

          (g) Governmental Approvals.  All necessary consents or authorizations
     from any Governmental or Regulatory Authority which may be required in
     connection with the transactions contemplated hereby, including the FCC and
     state public utility or service commissions or similar agencies, shall have
     been received and, in the case of the FCC, shall have become Final Orders
     (unless this requirement of finality is waived by DT in its sole
     discretion), unless the failure to receive any such consent or
     authorization would not have a Material Adverse Effect on Powertel or DT or
     the transactions contemplated by this Agreement, and such consents or
     authorizations shall not contain any conditions which would reasonably be
     expected to have a Material Adverse Effect on Powertel or DT or the
     transactions contemplated by this Agreement.

     Authority shall have issued an order, decree or ruling or taken any other

     reasonable best efforts to lift), in each case permanently restraining,
     enjoining or otherwise prohibiting the Merger;

          (d) By Powertel, (i) if DT shall have breached or failed to perform in
     any material respect any of its representations, warranties, covenants or

     perform (A) is incapable of being cured by DT prior to the Termination
     Date, or, if capable of being cured, is not cured by DT within 30 days
     after written notice thereof shall have been received by DT from Powertel
     and (B) renders any condition under Section 6.01 or 6.02 incapable of being

     Termination Date, or, if capable of being cured, is not cured by Powertel
     within 30 days after written notice thereof shall have been received by
     Powertel from DT and (B) renders any condition under Section 6.01 or 6.03
     incapable of being satisfied prior to the Termination Date or (ii) if a
     condition under Section 6.01 or 6.03 to DT's obligations hereunder is or

     to the Merger, Powertel, DT, VoiceStream or any of their Subsidiaries is
     required

     Agreement has been terminated at any time prior to the termination or
     consummation of the VoiceStream Merger Agreement;

     promulgated or enforced by any Governmental or Regulatory Authority (other
     than, for purposes of this paragraph only, any court of law or equity) and
     that has the effect of making the conditions set forth in Section 6.01(b),
     Section 6.01(c), Section 6.02(f) or Section 6.03(g) incapable of being
     satisfied by the Parties prior to the Termination Date; or

(except that, for the purposes of this Section 7.03(b), the applicable

been announced or otherwise publicly disclosed, and not withdrawn, and (ii)
within six months after the termination of this Agreement, Powertel enters into
a definitive agreement with any Third Party with respect to an Alternative
Transaction (provided that for any transaction referred to in clause (ii) of

otherwise provided in this paragraph, no Termination Fee shall be or become
payable upon termination of this Agreement.

above are an integral part of the transactions contemplated by this Agreement
and are an inducement to DT to enter into this Agreement and, to the extent
payable in connection with a breach of this Agreement, constitute liquidated
damages and not a penalty. If Powertel fails to promptly pay to DT any fee due
under such Section 7.03(b), then Powertel shall pay the costs and expenses
(including legal fees and expenses) in

                                      B-42

and Merger Sub pursuant to a writing adopted by action taken by each of them at

obligations or other acts of the others, (ii) waive any inaccuracies in the

                      AGREEMENT AND PLAN OF REORGANIZATION

     AGREEMENT AND PLAN OF REORGANIZATION dated as of August 26, 2000, as

     WHEREAS, VoiceStream and Deutsche Telekom AG, an AKTIENGESELLSCHAFT ("DT"),

amended or modified from time to time, the "DT MERGER AGREEMENT"), providing for
the acquisition of VoiceStream by DT (the "DT MERGER");

     WHEREAS, Powertel and DT entered into a separate merger agreement dated as
of August 26, 2000 (as amended or modified from time to time, the "POWERTEL
MERGER AGREEMENT"), providing for the acquisition of Powertel by DT (the
"POWERTEL MERGER"), subject to certain closing conditions, including the

     WHEREAS, VoiceStream and Powertel desire to provide for the acquisition of

     WHEREAS, the respective Boards of Directors of VoiceStream, Sub and

value per share and together with all accrued and unpaid dividends thereon
(calculated as if the Closing Date were a dividend payment date) (the "POWERTEL
PREFERRED STOCK," and collectively with Powertel Common Stock, the "POWERTEL
STOCK"), other than shares of Powertel Stock owned directly or indirectly by
VoiceStream or Powertel, will be converted into shares of common stock, $0.001
par value, of VoiceStream (the "VOICESTREAM COMMON STOCK");

     WHEREAS, the respective Boards of Directors of VoiceStream, Sub and
Powertel have determined that the Reorganization is in furtherance of and
consistent with their respective long-term business strategies and is fair to
and in the best interests of their respective stockholders;

     WHEREAS, the Board of Directors of Sub has determined that it is advisable
and in the best interests of Sub and its stockholder to consummate the Merger
and the other transactions contemplated hereby and has authorized the execution
and delivery of this Agreement, and VoiceStream, as Sub's current sole

                                       C-1
<PAGE>   428

"POWERTEL STOCKHOLDER AGREEMENT"), providing for certain actions relating to the
transactions contemplated by this Agreement;

     WHEREAS, as a condition to the willingness of, and as an inducement to,
Powertel to enter into this Agreement, contemporaneously with the execution and
delivery of this Agreement certain holders of VoiceStream Common Stock and

for certain actions relating to the transactions contemplated by this Agreement;
and

     WHEREAS, VoiceStream, Sub and Powertel desire to make certain
representations, warranties, covenants and agreements in connection with the
Reorganization and also to prescribe various conditions to the Reorganization.

     NOW, THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements herein contained, and intending to be legally bound hereby,
VoiceStream, Sub and Powertel hereby agree as follows:

                                   ARTICLE I

                               THE REORGANIZATION

     SECTION 1.01  The Merger.  Upon the terms and subject to the conditions
hereof, and in accordance with the DGCL, in the Reorganization, Sub shall be
merged with and into Powertel at the Effective Time. Following the Effective
Time, the separate corporate existence of Sub shall cease, and Powertel shall
continue as the surviving corporation (the "SURVIVING CORPORATION") and shall
succeed to and assume all the rights and obligations of Sub and Powertel in
accordance with the DGCL.

     SECTION 1.02  Closing.  The closing (the "CLOSING") of the Merger will take
place at 10:00 a.m., Seattle time, on the fifth Business Day after satisfaction
or waiver of the conditions set forth in ARTICLE VI (excluding conditions that,
by their terms, cannot be satisfied except at the Closing), at the offices of
Preston, Gates & Ellis LLP, 701 Fifth Avenue, Suite 5000, Seattle, WA
98104-7078, unless this Agreement shall have been terminated and the
transactions contemplated by this Agreement abandoned pursuant to ARTICLE VII or
unless another date, time or place is agreed to in writing by the parties
hereto. The date on which the Closing takes place is herein referred to as the
"CLOSING DATE."

     SECTION 1.03  Effective Time.  The Merger shall become effective when a
Certificate of Merger (the "CERTIFICATE OF MERGER"), executed in accordance with
the relevant provisions of the DGCL, is duly filed with the Secretary of State
of the State of Delaware, or at such other time as Sub and Powertel shall agree
should be specified in the Certificate of Merger. The term "EFFECTIVE TIME"
shall mean the later of the date and time at which the Certificate of Merger is
duly filed with the Secretary of State of the State of Delaware or such other
time established by the Certificate of Merger. The filing of the Certificate of
Merger shall be made on the Closing Date as soon as practicable after the
satisfaction or waiver of the conditions set forth herein.

     SECTION 1.04  Effects of the Merger.  At the Effective Time, the effect of
the Merger shall be as provided in this Agreement and in the applicable
provisions of the DGCL. Without limiting the generality of the foregoing, and
subject thereto, at the Effective Time, all the assets, property, rights,
privileges, immunities, powers and franchises of Powertel and Sub shall vest in
the Surviving Corporation, and all debts, liabilities and duties of Powertel and
Sub shall become the debts, liabilities and duties of the Surviving Corporation.

     SECTION 1.05  Restated Certificate of Incorporation and By-laws; Officers
and Directors.

     (a) The Restated Certificate of Incorporation of Powertel, as in effect
immediately prior to the Effective Time, shall be amended as of the Effective
Time as set forth on ANNEX A hereto. As so amended, such Restated Certificate of
Incorporation shall be the Certificate of Incorporation of the Surviving
Corporation until thereafter changed or amended as provided therein or by
applicable law.

                                       C-2
<PAGE>   429

     (b) The Restated By-laws of Powertel, as in effect immediately prior to the
Effective Time, shall be amended as of the Effective Time as set forth on ANNEX
B hereto. As so amended, such Restated By-laws shall be the By-laws of the
Surviving Corporation until thereafter changed or amended as provided therein or
by applicable law.

     (c) The directors of Sub immediately prior to the Effective Time shall be
the directors of the Surviving Corporation, until the next annual meeting of
stockholders (or the earlier of their resignation or removal) and until their
respective successors are duly elected and qualified, as the case may be.

     (d) The officers of Sub immediately prior to the Effective Time shall be
the officers of the Surviving Corporation until the earlier of their resignation
or removal and until their respective successors are duly elected and qualified,
as the case may be.

     SECTION 1.06  Effect on Stock.  As of the Effective Time, by virtue of the
Merger and without any action on the part of any party hereto or the holders of
any securities of Powertel and Sub:

          (a) Capital Stock of Sub.  Each issued and outstanding share of
     capital stock of Sub shall be converted into and become one validly issued,
     fully paid and nonassessable share of common stock, no par value, of the
     Surviving Corporation.

          (b) Treasury Stock and VoiceStream Owned Stock.  Each share of
     Powertel Stock that is owned by Powertel or by any Powertel Subsidiary and
     each share of Powertel Stock that is owned by VoiceStream, Sub or any other
     VoiceStream Subsidiary shall automatically be cancelled and retired and
     shall cease to exist, and no consideration shall be delivered in exchange
     therefor.

          (c) Conversion of Powertel Stock.  At the Effective Time: (i) each
     share of Powertel Common Stock issued and outstanding shall be converted
     automatically into the right to receive a number (as calculated below, the
     "CONVERSION NUMBER") of validly issued, fully paid and nonassessable shares
     of VoiceStream Common Stock; and (ii) each share of Powertel Preferred
     Stock issued and outstanding, whether or not such share is convertible by
     its terms as of the Effective Time, shall be converted automatically into
     the right to receive a number of shares of validly issued, fully paid and
     nonassessable shares of VoiceStream Common Stock determined by multiplying
     (A) the Conversion Number by (B) the sum of (1) the number of shares of
     Powertel Common Stock into which such share of Powertel Preferred Stock
     would be converted as of the Effective Time, if such share were then
     convertible and had been converted, plus (2) with respect to the Series E
     Preferred Shares and Series F Preferred Shares, the number of shares of
     Powertel Common Stock that represent accrued or declared but unpaid
     dividends on such shares (calculated as if the Closing Date were a dividend
     payment date). The Conversion Number shall be determined as follows: (i)
     0.75 if the VoiceStream Average Closing Price is $113.33 or below; (ii)
     0.65 if the VoiceStream Average Closing Price is $130.77 or above; and
     (iii) if the VoiceStream Average Closing Price is greater than $113.33 and
     less than $130.77, the quotient determined by dividing $85.00 by the
     VoiceStream Average Closing Price. The "VOICESTREAM AVERAGE CLOSING PRICE"
     shall mean the volume weighted average closing price (based on the Nasdaq
     National Market System ("NASDAQ") composite volume published by the Wall
     Street Journal) of the VoiceStream Common Stock as publicly reported for
     the Nasdaq as of 4:00 p.m. Eastern Time for ten (10) trading days randomly
     selected by lot out of the last twenty (20) trading days ending five (5)
     trading days prior to the Closing Date. As of the Effective Time, all such
     shares of Powertel Stock shall be converted in accordance with this
     paragraph, and when so converted, shall no longer be outstanding and shall
     automatically be cancelled and retired and shall cease to exist, and each
     holder of a certificate representing any such shares of Powertel Stock
     shall cease to have any rights with respect thereto, except the right to
     receive (i) certificates representing the shares of VoiceStream Common
     Stock into which such shares of Powertel Stock have been converted, (ii)
     any dividends and other distributions in accordance with SECTION 1.07(d)
     and (iii) any cash, without interest, to be paid in lieu of any fractional
     share of VoiceStream Common Stock in accordance with SECTION 1.07(e). ITEM
     1.06(c) of the Powertel Letter sets forth a pro forma calculation of the
     conversion of Powertel Common Stock and each outstanding Powertel Common
     Stock Equivalent (including the corresponding conversion ratios with
     respect to each series of
                                       C-3
<PAGE>   430

     Powertel Preferred Stock) into VoiceStream Common Stock or VoiceStream
     Equity Rights as of the date hereof.

          (d) Assumption of Options, Warrants and Puts.  Subject to SECTION 5.02
     hereof, Powertel and VoiceStream shall take all requisite action such that,
     at the Effective Time, (i) all Powertel Stock Options outstanding at the
     Effective Time, (ii) all obligations of Powertel with respect to the
     warrants (the "POWERTEL WARRANTS") to purchase Powertel Common Stock issued
     by Powertel pursuant to the Warrant Agreement (the "WARRANT AGREEMENT")
     dated February 7, 1996 between Powertel and Bankers Trust Company, as
     warrant agent, outstanding at the Effective Time, (iii) all obligations
     with respect to the Stock Purchase Agreement and the Put Agreement, each
     dated May 30, 2000 between Powertel and Sonera Holding B.V. (together, the
     "SONERA PUT") and (iv) all obligations with respect to the Put Agreement
     dated May 30, 2000 and between Powertel, Eliska Wireless Investors I, L.P.
     and Sonera Holding B.V. (the "ELISKA PUT" and together with the Sonera Put,
     the "ELISKA PUT RIGHTS") shall be specifically assumed by VoiceStream in
     writing.

          (e) Adjustment of Conversion Number.  In the event of any
     reclassification, stock split or stock dividend with respect to VoiceStream
     Common Stock, any change, exchange or conversion of VoiceStream Common
     Stock into other securities or property, or any other dividend or
     distribution with respect to VoiceStream Common Stock (other than normal
     quarterly cash dividends as the same may be modified from time to time in
     the ordinary course), or if a record date with respect to any of the
     foregoing should occur, prior to the Effective Time, appropriate and
     proportionate adjustments, if any, shall be made to the Conversion Number,
     and thereafter all references in this Agreement to the Conversion Number
     shall be deemed to be to the Conversion Number as so adjusted.

     In the event that the aggregate number of shares of Powertel Common Stock
and Powertel Common Stock Equivalents ("ADJUSTED FULLY DILUTED SHARES") exceeds
the Maximum Share Amount as of the Effective Time, excluding, for purposes of
this SECTION 1.06(e), Powertel Common Stock issuable after the date hereof and
prior to the Effective Time in respect of dividends accrued on the Series E
Preferred Shares and the Series F Preferred Shares, the Conversion Number shall
be adjusted by multiplying the Conversion Number otherwise applicable under
SECTION 1.06(c) by a fraction the numerator of which shall be the Maximum Share
Amount and the denominator of which shall be the number of Adjusted Fully
Diluted Shares as of the Effective Time. Except as described in the preceding
sentence, the number of shares of Powertel Common Stock and Powertel Common
Stock Equivalents for the purpose of such recalculation shall be determined in
the same manner as described in ITEM 1.06(c) of the Powertel Letter, including
shares of Powertel Common Stock issuable (i) in exchange for Powertel Preferred
Stock, (ii) pursuant to Powertel Stock Options and Powertel Warrants, (iii)
pursuant to Powertel Restricted Stock Awards, (iv) in connection with the Eliska
Put Rights, (v) pursuant to the Sonera Stock Purchase Agreement (as defined
below) and (vi) any other Powertel Common Stock and Powertel Common Stock
Equivalents outstanding as of the Effective Time. For purposes of this SECTION
1.06(e), the "MAXIMUM SHARE AMOUNT" means 55,742,000 shares; provided, however,
that if prior to the Effective Time the Stock Purchase Agreement between
Powertel and Sonera B.V. relating to the DiGiPH Transaction (the "SONERA STOCK
PURCHASE AGREEMENT") or the Eliska Put or the Sonera Put shall have been
terminated, the Maximum Share Amount shall be appropriately reduced.

     SECTION 1.07  Surrender of Certificates.

     (a) Exchange Agent.  ChaseMellon Shareholder Services LLC shall act as
exchange agent in the Merger (the "EXCHANGE AGENT"). As and when needed, but no
later than twenty-five (25) Business Days after the Effective Time, VoiceStream
shall deposit with the Exchange Agent, in trust for the holders of certificates
(the "POWERTEL CERTIFICATES") which immediately prior to the Effective Time
represented shares of Powertel Stock converted in the Merger, certificates (the
"VOICESTREAM CERTIFICATES") representing the shares of VoiceStream Common Stock
issuable pursuant to SECTION 1.06(c) (such shares of VoiceStream Common Stock,
together with cash in lieu of fractional shares and any dividends, securities,
property or distributions with respect thereto payable in accordance with
SECTION 1.07(d) being hereinafter referred to as the "EXCHANGE FUND").

                                       C-4
<PAGE>   431

     (b) Exchange Procedure.  As soon as reasonably practicable after the
Effective Time, but no later than five (5) Business Days after the Effective
Time, the Surviving Corporation shall cause the Exchange Agent to mail to each
holder of record of a Powertel Certificate, (i) a letter of transmittal (which
shall specify that delivery shall be effected, and risk of loss and title to a
Powertel Certificate shall pass, only upon delivery of such Powertel Certificate
to the Exchange Agent and shall be in a form and have such other provisions as
VoiceStream may reasonably specify), and (ii) instructions for use in effecting
the surrender of Powertel Certificates in exchange for the property described in
the next sentence. Upon surrender for cancellation to the Exchange Agent of any
Powertel Certificate(s) held by any holder of record of a Powertel Certificate,
together with such letter of transmittal duly executed, such holder shall be
entitled to receive in exchange therefor a VoiceStream Certificate (which shall
not include any restrictive legends but may be subject to the agreement signed
by Rule 145 Affiliates pursuant to SECTION 5.08(a) of this Agreement)
representing the number of whole shares of VoiceStream Common Stock into which
the shares of Powertel Stock represented by the surrendered Powertel
Certificate(s) shall have been converted at the Effective Time pursuant to
SECTION 1.06(c), cash in lieu of any fractional share of VoiceStream Common
Stock in accordance with SECTION 1.07(e) and the dividends and other
distributions in accordance with SECTION 1.07(d); and the Powertel
Certificate(s) so surrendered shall forthwith be cancelled. In the event of a
transfer of ownership of shares of Powertel Stock that is not registered in the
transfer records of Powertel, cash or a VoiceStream Certificate representing
shares of VoiceStream Common Stock may be paid to or issued in a name other than
that in which the Powertel Certificate surrendered in exchange therefor is
registered, if such Powertel Certificate shall be properly endorsed or otherwise
be in proper form for transfer and the person requesting such payment shall pay
any transfer or other Taxes required by reason of the payment to a person other
than the registered holder of such Powertel Certificate or establish to the
satisfaction of the Surviving Corporation that such Tax has been paid or is not
applicable. Until surrendered as contemplated by this SECTION 1.07, each
Powertel Certificate shall be deemed at any time after the Effective Time to
represent only (A) the right to receive VoiceStream Certificates representing
the shares of VoiceStream Common Stock into which the shares of Powertel Stock
represented by such Powertel Certificate have been converted, (B) any dividends
and other distributions in accordance with SECTION 1.07(d), and (C) any cash,
without interest, to be paid in lieu of any fractional share of VoiceStream
Common Stock in accordance with SECTION 1.07(e). VoiceStream or the Exchange
Agent shall be entitled to deduct and withhold from the consideration otherwise
payable pursuant to this Agreement to any holder of shares of Powertel Stock
such amounts as VoiceStream or the Exchange Agent is required to deduct and
withhold with respect to the making of such payment under the Code or under any
provision of state, local or foreign Tax law, but in connection therewith shall
be obligated to pay over to the proper Tax authorities and properly report such
payment as required by such Tax law. To the extent that amounts are so withheld
by VoiceStream or the Exchange Agent (but not both) and have been properly paid
to the appropriate Tax authorities and reported as required by law, such
withheld amounts shall be treated for all purposes of this Agreement as having
been paid to the holder of the shares of Powertel Stock in respect of which such
deduction and withholding was made by VoiceStream or the Exchange Agent.

     (c) No Further Ownership Rights in Shares.  All shares of VoiceStream
Common Stock issued and cash paid upon the surrender of Powertel Certificates in
accordance with the terms of this ARTICLE I (including any cash paid pursuant to
SECTION 1.07(d) or SECTION 1.07(e)) shall be deemed to have been issued (and
paid) in full satisfaction of all rights pertaining to the shares of Powertel
Stock theretofore represented by such Powertel Certificates. At the Effective
Time, the stock transfer books of Powertel shall be closed, and there shall be
no further registration of transfers on the stock transfer books of the
Surviving Corporation of the shares of Powertel Stock that were outstanding
immediately prior to the Effective Time. If, after the Effective Time, Powertel
Certificates are presented to the Surviving Corporation or the Exchange Agent
for any reason, they shall be cancelled and exchanged as provided in this
ARTICLE I.

     (d) Dividends.  No dividends or other distributions that are declared on or
after the Effective Time on VoiceStream Common Stock, or are payable to the
holders of record thereof on or after the Effective Time, shall be paid to any
person entitled by reason of the Merger to receive VoiceStream Certificates,
                                       C-5
<PAGE>   432

and no cash payment in lieu of any fractional share of VoiceStream Common Stock
shall be paid to any such person pursuant to SECTION 1.07(e), until such person
shall have surrendered its Powertel Certificate(s) as provided in SECTION
1.07(b). Subject to applicable law, there shall be paid to each person receiving
a VoiceStream Certificate: (i) at the time of such surrender or as promptly as
practicable thereafter, the amount of any dividends or other distributions
theretofore paid with respect to the shares of VoiceStream Common Stock
represented by such VoiceStream Certificate and having a record date on or after
the Effective Time and a payment date prior to such surrender; and (ii) at the
appropriate payment date or as promptly as practicable thereafter, the amount of
any dividends or other distributions payable with respect to such shares of
VoiceStream Common Stock and having a record date on or after the Effective Time
but prior to such surrender and a payment date on or subsequent to such
surrender. In no event shall the person entitled to receive such dividends or
other distributions be entitled to receive interest on such dividends or other
distributions.

     (e) No Fractional Shares.  No certificates or scrip representing fractional
shares of VoiceStream Common Stock shall be issued upon the surrender for
exchange of Powertel Certificates pursuant to this ARTICLE I; and no such
fractional share shall entitle the record or beneficial owner thereof to vote or
to any other rights of a stockholder of VoiceStream. In lieu of any such
fractional share, each holder of shares of Powertel Stock who would otherwise
have been entitled thereto upon the surrender of Powertel Certificate(s) for
exchange pursuant to this ARTICLE I will be paid an amount in cash (without
interest), rounded to the nearest whole cent, determined by multiplying (i) the
per share closing price on the Nasdaq of VoiceStream Common Stock (as reported
on the Nasdaq) on the date on which the Effective Time shall occur (or, if
VoiceStream Common Stock shall not trade on the Nasdaq on such date, the first
day of trading in VoiceStream Common Stock on the Nasdaq thereafter) by (ii) the
fractional share to which such holder would otherwise be entitled.

     (f) Termination of Exchange Fund.  Any portion of the Exchange Fund which
remains undistributed to holders of Powertel Stock for twelve (12) months after
the Effective Time shall be delivered to VoiceStream, upon demand, and any
holders of Powertel Stock who have not theretofore complied with this ARTICLE I
and the instructions set forth in the letter of transmittal mailed to such
holders after the Effective Time shall thereafter look only to the Surviving
Corporation (subject to abandoned property, escheat or other similar laws) only
as general creditors thereof for payment of shares of VoiceStream Common Stock,
any cash in lieu of fractional shares of VoiceStream Common Stock and any
dividends or distributions with respect to such shares of VoiceStream Common
Stock to which they are entitled.

     (g) No Liability.  None of VoiceStream, Sub, Powertel, the Surviving
Corporation or the Exchange Agent shall be liable to any Person in respect of
any VoiceStream Common Stock or cash delivered to a public official pursuant to
any applicable abandoned property, escheat or similar law.

     (h) Lost Certificates.  If any Powertel Certificate is lost, stolen or
destroyed, upon the making of an affidavit of that fact by the Person claiming
such Powertel Certificate to be lost, stolen or destroyed and executing an
indemnity reasonably satisfactory to VoiceStream (and, if required by
VoiceStream, the posting by such Person of a bond, in such reasonable amount as
VoiceStream may direct, as indemnity) indemnifying VoiceStream against any claim
that may be made against VoiceStream with respect to the Powertel Certificate,
the Exchange Agent will issue, in exchange for such lost, stolen or destroyed
Powertel Certificate, the consideration to be paid in respect of the shares
represented by such Powertel Certificate. Such Person additionally will be
entitled to receive any amounts payable pursuant to SECTION 1.07(d) and/or
SECTION 1.07(e).

                                   ARTICLE II

liability company duly organized, validly existing and is in good standing
(where such concept is applicable) under the laws of the jurisdiction of its
incorporation or organization and has the requisite power and authority to carry
on its business as now being conducted, except where the failure to be so
organized, existing and in good standing or to have such power and authority
could not reasonably be expected to have a Material Adverse Effect on Powertel
or prevent or materially delay the consummation of the Reorganization. Powertel
and each of the Powertel Subsidiaries is duly qualified or licensed to do
business and is in good standing (where such concept is applicable) in each
jurisdiction in which the nature of its business or the ownership or leasing of
its properties makes such qualification or licensing necessary, except in such
jurisdictions where the failure to be so duly qualified or licensed and in good
standing could not reasonably be expected to have a Material Adverse Effect on
Powertel or prevent or materially delay the consummation of the Reorganization.
Powertel has delivered to VoiceStream complete and correct copies of the
Restated Certificate of Incorporation of Powertel and Restated By-laws of
Powertel and has made available to VoiceStream the certificate of incorporation

shares of capital stock of each Powertel Subsidiary are owned by Powertel or by
another Powertel Subsidiary free and clear of all Liens, except for Liens which
are granted to secure indebtedness and are disclosed in ITEM 2.02 of the
Powertel Letter. Except as set forth in ITEM 2.02 of the Powertel Letter, (i)
Powertel and the Powertel Subsidiaries have no material ongoing obligations,
agreements, commitments, rights, understandings or arrangements with respect to
any Investment Entities, including funding obligations; and (ii) all Investment
Interests are owned by Powertel or the Powertel Subsidiaries free and clear of
all Liens. Except as set forth in ITEM 2.02 of the Powertel Letter and except

Subsidiaries, neither Powertel nor any of the Powertel Subsidiaries owns,
directly or indirectly, any capital stock or other ownership interest in any
corporation, partnership, joint venture, limited liability company or other
entity.

violate or conflict with the Restated Certificate of Incorporation or Restated
By-laws of Powertel or of the similar organizational documents of any of the
Powertel Subsidiaries, (ii) require any filing with, or permit, authorization,
consent or approval of, any Governmental Entity (except where the failure to

filings could not reasonably be expected to have a Material Adverse Effect on
Powertel or prevent or materially delay the consummation of the Reorganization),
(iii) result in a violation or breach of, or constitute (with or without due
notice or lapse of time or both) a default (or give rise to any right of
termination, amendment, cancellation or acceleration) under, any of the terms,
conditions or

on Powertel or prevent or materially delay the consummation of the
Reorganization.

     SECTION 2.06  SEC Documents and Other Reports.  Powertel has filed with the
SEC all documents required to be filed by it since January 1, 1997 under the
Securities Act or the Exchange Act (the "POWERTEL SEC DOCUMENTS"). As of their
respective filing dates, the Powertel SEC Documents were prepared substantially
in accordance with the requirements of the Securities Act or the Exchange Act,
as the case may be, each as in effect on the date so filed, and at the time
filed with the SEC (or if amended or superseded by a filing prior to the date
hereof, then on the date of such filing) none of the Powertel SEC Documents
contained any untrue statement of a material fact or omitted to state a material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances under which they were made, not misleading. The
financial statements of Powertel included in the Powertel SEC Documents have
been prepared in accordance with generally accepted accounting principles
(except in the case of the unaudited statements permitted by Form 10-Q under the
Exchange Act) applied on a consistent basis during the periods involved (except
as may be indicated therein or in the notes thereto) and fairly present the
consolidated financial position of Powertel and the consolidated Powertel
Subsidiaries as of the respective dates thereof and the consolidated results of
operations and consolidated cash flows for the periods then ended (subject, in
the case of unaudited statements, to normal year-end audit adjustments and to
any other adjustments described therein).

Subsidiaries have conducted their respective businesses in all material respects
only in the ordinary course, consistent with past practices, and there has not
been (i) any Material Adverse Change with respect to Powertel, (ii) any

assets, liabilities or business, except insofar as may have been required by a
change in generally accepted accounting principles.

     SECTION 2.08  Information Supplied.  None of the information supplied or to
be supplied by Powertel specifically for inclusion or incorporation by reference
in (i) the Registration Statement or (ii) the joint proxy statement (together
with any amendments or supplements thereto, the "JOINT PROXY STATEMENT")
relating to the Stockholder Meetings will, in the case of the Registration
Statement, at the time it becomes effective, contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading, or in the case of the
Joint Proxy Statement, at the time of the mailing of the Joint Proxy Statement
or the time of the Stockholder Meetings, contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary in order to make the statements therein, in light of the

any other Person who is not an Affiliate of Powertel that is contained in the
Registration Statement or the Joint Proxy Statement.

     SECTION 2.09  Permits; Compliance with Laws.  (a) Each of Powertel and the
Powertel Subsidiaries is in possession of all franchises, grants,
authorizations, licenses, permits, charters, easements, variances, exceptions,
consents, certificates, approvals and orders of any Governmental Entity
necessary for Powertel or any of the Powertel Subsidiaries to own, lease and
operate its properties or to carry on its business as it is now being conducted
(the "POWERTEL PERMITS"), except where the failure to have any of the Powertel
Permits could not, individually or in the aggregate, have a Material Adverse
Effect on Powertel, and, as of the date of this Agreement, no suspension or
cancellation of any of the Powertel Permits is pending or, to the knowledge of
Powertel, threatened, except where the suspension or cancellation of any of the
Powertel Permits could not, individually or in the aggregate, reasonably be
expected to have a Material Adverse Effect on Powertel. The business of Powertel
and the Powertel Subsidiaries is not being conducted in violation of any law,
ordinance or regulation of any Governmental Entity, except for possible
violations that could not reasonably be expected to have a Material Adverse
Effect on Powertel or prevent or materially delay the consummation of the
Reorganization. None of the representations and warranties made in this SECTION
2.09 are being made with respect to Environmental Laws.

     (b) Except as set forth in ITEM 2.09 of the Powertel Letter:

          (i) Powertel and each of the Powertel Subsidiaries holds, and is
     qualified and eligible to hold, all material licenses, permits and other
     authorizations issued or to be issued by the FCC to such entity for the
     operation of their respective businesses, all of which are set forth in
     ITEM 2.09 of the Powertel Letter (the "POWERTEL FCC LICENSES"). Each of the
     Powertel FCC Licenses that is subject to restrictions under Section 310(b)
     of the Communications Act is held by a Powertel Subsidiary.

          (ii) The Powertel FCC Licenses are valid and in full force and effect,
     and neither Powertel nor any of the Powertel Subsidiaries is or has been
     delinquent in payment on or in default under any installment obligation
     owed to the United States Treasury in connection with the Powertel FCC
     Licenses. As used herein, the term "full force and effect" means that (A)
     the orders issuing the Powertel FCC Licenses have become effective, (B) no
     stay of effectiveness of such orders has been issued by the FCC, and (C)
     the Powertel FCC Licenses have not been invalidated by any subsequent
     published FCC action.

          (iii) All material reports and applications required by the
     Communications Act or required to be filed with the FCC by Powertel or any
     of the Powertel Subsidiaries have been filed and are accurate and complete
     in all material respects.

          (iv) Powertel and the Powertel Subsidiaries are, and have been, in
     compliance in all material respects with, and the wireless communications
     systems operated pursuant to the Powertel FCC Licenses are and have been
     operated in compliance in all material respects with, the Communications
     Act.

          (v) There is not pending or, to Powertel's knowledge, threatened, as
     of the date hereof any application, petition, objection, pleading or
     proceeding with the FCC or any public service commission or similar body
     having jurisdiction or authority over the communications operations of
     Powertel or any of the Powertel Subsidiaries which is reasonably likely to
     result in the revocation, cancellation, suspension, dismissal, denial or
     any materially adverse modification of any Powertel FCC License or
     imposition of any substantial fine or forfeiture against Powertel or any of
     the Powertel Subsidiaries.

          (vi) No facts are known to Powertel or the Powertel Subsidiaries which
     if known by a Governmental Entity of competent jurisdiction would present a
     substantial risk that any Powertel FCC License could be revoked, cancelled,
     suspended or materially adversely modified or that any substantial fine or
     forfeiture could be imposed against Powertel or any of the Powertel
     Subsidiaries.

<PAGE>   438

          (vii) Powertel and the Powertel Subsidiaries have not made any
     material misstatements of fact, or omitted to disclose any fact, to any
     Government Entity or in any report, document or certificate filed
     therewith, which misstatements or omissions, individually or in the
     aggregate, could reasonably be expected to subject any Powertel FCC
     Licenses to revocation or failure to renew, except to the extent that such
     revocation or failure to renew would not have a Material Adverse Effect on
     Powertel or the transactions contemplated by this Agreement.

     SECTION 2.10  Tax Matters.  Except as set forth in ITEM 2.10 of the
Powertel Letter or as would not have a Material Adverse Effect on Powertel: (i)

them either on a separate or combined or consolidated basis; (ii) all such Tax
Returns are correct in all respects and accurately disclose in all respects all
Taxes required to be paid for the periods covered thereby; (iii) Powertel and
the Powertel Subsidiaries have paid or caused to be paid all Taxes shown as due

filed, and the financial statements contained in the Powertel SEC Documents
reflect an adequate reserve as determined in accordance with generally accepted
accounting principles for all material Taxes payable by Powertel and the
Powertel Subsidiaries and not yet due (other than a reserve for deferred Taxes
established to reflect timing differences between book and Tax treatment) for
all taxable periods and portions thereof accrued through the date of such
financial statements; (iv) none of Powertel or any Powertel Subsidiary has
waived in writing any statute of limitations in respect of Taxes; (v) there is

Section 162(m) of the Code; (x) neither Powertel nor any of the Powertel
Subsidiaries has constituted either a "distributing corporation" or a
"controlled corporation" in a distribution of stock qualifying for tax-free
treatment under Section 355 of the Code (a) in the two (2) years prior to the

Section 355(e) of the Code) in conjunction with the Reorganization; (xi) neither
Powertel nor any of the Powertel Subsidiaries is a "United States real property
holding corporation" within the meaning of Section 897(c)(2) of the Code; (xii)
none of Powertel, VoiceStream or any of their Subsidiaries will be obligated to
make a payment, in connection with the transactions contemplated hereunder or
otherwise, to any employee or former employee of, or individual providing
services to, Powertel or any Powertel Subsidiary that would be a "parachute
payment" to a "disqualified individual" as those terms are defined in Section
280G of the Code without regard to whether such payment is reasonable
compensation for personal services performed or to be performed in the future;
and (xiii) none of Powertel, VoiceStream or any of their Subsidiaries will be
obligated to pay any excise taxes or similar taxes imposed on any employee or
former employee of, or individual providing services to, Powertel or any
Powertel Subsidiary under Section 4999 of the Code or any similar provisions as
a result of the consummation of the transactions contemplated hereby, either
alone or in connection with any other event.

     SECTION 2.11  Liabilities.  Except as set forth in the Powertel Filed SEC
Documents or ITEM 2.11 of the Powertel Letter, and as permitted by this
Agreement and the Powertel Merger Agreement, Powertel and the Powertel
Subsidiaries, taken as a whole, do not have any liabilities or obligations of
any nature (whether accrued, absolute, contingent or otherwise) required by
generally accepted accounting principles to be set forth on a consolidated
balance sheet of Powertel and the Powertel Subsidiaries or in the notes thereto,
other than (i) liabilities and obligations incurred in the ordinary course of

<PAGE>   439

December 31, 1999 or (ii) liabilities arising after December 31, 1999 which
could not, individually or in the aggregate, reasonably be expected to have a
Material Adverse Effect on Powertel.

     SECTION 2.12  Benefit Plans; Employees and Employment Practices.

     (a) Except as disclosed in the Powertel Filed SEC Documents or ITEM 2.12(a)
of the Powertel Letter, or to the extent required by law or required to maintain
compliance with provisions of the Code, neither Powertel nor any of the Powertel
Subsidiaries has adopted or amended in any material respect any ERISA Benefit
Plan of Powertel since the date of the most recent audited financial statements
included in the Powertel Filed SEC Documents. Except as set forth in ITEM
2.12(a) of the Powertel Letter, Powertel does not have any commitment to create,
adopt or contribute to any Powertel Benefit Plan. Except as disclosed in ITEM
2.12(a) of the Powertel Letter or in the Powertel Filed SEC Documents, as of the
date of this Agreement, there exist no material employment, consulting,
severance, bonus, incentive or termination agreements between Powertel or any of
the Powertel Subsidiaries and any current or former employee, officer or
director of Powertel or any of the Powertel Subsidiaries.

     (b) ITEM 2.12(b) of the Powertel Letter contains a list of all the Powertel
Benefit Plans. None of Powertel, any of the Powertel Subsidiaries, any officer
of Powertel or any of the Powertel Subsidiaries or any of the ERISA Benefit
Plans has on or before the date of this Agreement engaged in a "prohibited
transaction" (as defined in Section 406 of ERISA or Section 4975 of the Code)
with respect to any ERISA Benefit Plan that could reasonably be expected to
subject Powertel, any of the Powertel Subsidiaries or any officer of Powertel or
any of the Powertel Subsidiaries to any Tax on prohibited transactions imposed
by Section 4975 of the Code or to any liability under Section 502(i) or (l) of
ERISA where such Tax or liability has or would be reasonably expected to have a
Material Adverse Effect on Powertel. No ERISA Benefit Plan has incurred any
"accumulated funding deficiency" (as defined in Section 412 of the Code or Part
3 of Title I of ERISA), whether or not waived. Neither Powertel nor any of the
Powertel Subsidiaries has incurred and none of such entities reasonably expects
to incur, any material liability to the PBGC with respect to any ERISA Benefit
Plan. No assets of Powertel or any of the Powertel Subsidiaries are subject to
Liens arising under ERISA or the Code on account of any ERISA Benefit Plan,
neither Powertel nor any of the Powertel Subsidiaries has been required to
provide any security under Sections 401(a)(29) or 412(f) of the Code, or under
Section 307 of ERISA, and, to Powertel's knowledge, no event has occurred that
could give rise to any such Lien or a requirement to provide any such security.
Except as disclosed in ITEM 2.12(b) of the Powertel Letter, none of Powertel,
the Powertel Subsidiaries or any ERISA Affiliate has at any time during the
five-year period preceding the date hereof contributed to any "multiemployer
plan" (as defined in Section 3(37) of ERISA).

     (c) Except as disclosed in ITEM 2.12(c) of the Powertel Letter, and except
for such matters as could not be reasonably expected to have a Material Adverse
Effect on Powertel, to the extent applicable, (i) each ERISA Benefit Plan
complies with the requirements of ERISA and the Code, (ii) each ERISA Benefit
Plan intended to be qualified under Section 401(a) of the Code has been
determined by the Internal Revenue Service to be so qualified and nothing has
occurred since the date of that determination that could reasonably be expected
to adversely affect the qualified status of such plan and its related trust is
tax-exempt and has been so since its creation, and (iii) each Powertel Benefit
Plan has been maintained, administered and operated in compliance with its terms
and with the requirements prescribed by any and all statutes, orders, rules and
regulations, including but not limited to ERISA and the Code, which are
applicable to such Powertel Benefit Plans.

     (d) Except as disclosed in ITEM 2.12(d) of the Powertel Letter, all
material contributions, reserves or premium payments under or to the Powertel
Benefit Plans, accrued to the date hereof have been made or provided for.

     (e) Except as disclosed in ITEM 2.12(e) of the Powertel Letter, and except
for any liability as could not be reasonably expected to have a Material Adverse
Effect on Powertel, Powertel has not incurred any liability under Subtitle C or
D of Title IV of ERISA with respect to any "single-employer plan" within the
meaning of Section 4001(a)(15) of ERISA, currently or formerly maintained by
Powertel, or any entity which is considered one employer with Powertel under
Section 4001 of ERISA.

     (f) Except as disclosed in ITEM 2.12(f) of the Powertel Letter, neither
Powertel nor any of the Powertel Subsidiaries has any obligation to provide
retiree health or welfare benefits for any current or former employee under any
Powertel Benefit Plan, except as required by Part 6 of Title I of ERISA or to
avoid excise taxes under Section 4980B of the Code, and the terms of the
Powertel Benefit Plans permit Powertel to amend or terminate such Powertel
Benefit Plans at any time without incurring liability thereunder.

     (g) Except as disclosed in ITEM 2.12(g) of the Powertel Letter, Powertel
has not engaged in, nor is it a successor or parent corporation to an entity
that has engaged in a transaction described in Section 4069 of ERISA.

     (h) Except as disclosed in ITEM 2.12(h) of the Powertel Letter, the
consummation or announcement of any transaction contemplated by this Agreement
will not (either alone or upon the occurrence of any additional or further acts
or events) result in any (i) payment (whether of severance pay or otherwise)
becoming due from Powertel or any of the Powertel Subsidiaries to any officer,
employee, former employee or director thereof or to the trustee under any "rabbi
trust" or similar arrangement; (ii) benefit under any Powertel Benefit Plan
being established or becoming accelerated, vested or payable; or (iii)
"reportable event" (as defined in Section 4043 of ERISA) with respect to any
ERISA Benefit Plan subject to Title IV of ERISA.

     (i) Except as disclosed in ITEM 2.12(i) of the Powertel Letter, as of the
date of this Agreement there are no pending disputes, arbitrations, claims,
suits, grievances or, to the knowledge of Powertel, governmental audits
involving a Powertel Benefit Plan (other than routine claims for benefits
payable under any such Powertel Benefit Plan or routine audits) that would
reasonably be expected either individually or in the aggregate, to have a
Material Adverse Effect on Powertel.

     (j) ITEM 2.12(j) of the Powertel Letter contains a list setting forth the
name and current annual salary and other material compensation payable to each
Significant Employee, and the profit sharing, bonus or other form of additional
cash compensation paid or payable by Powertel or the Powertel Subsidiaries to or
for the benefit of each such person for the current fiscal year. Except as set
forth in ITEM 2.12(j) of the Powertel Letter, there are no oral or written
contracts, agreements or arrangements obligating Powertel or any of the Powertel
Subsidiaries to increase the compensation or benefits presently being paid or
hereafter payable to any Significant Employees or any oral employment or
consulting or similar arrangements regarding any Significant Employee that are
not terminable without liability on thirty (30) days' or less prior notice. ITEM
2.12(j) of the Powertel Letter lists all written employment and consulting
agreements with respect to any Significant Employee. Powertel has provided true
and correct copies of all employment agreements listed on ITEM 2.12(j) of the
Powertel Letter. Except for severance or retention obligations to Significant
Employees set forth in ITEM 2.12(j) or as otherwise set forth in ITEM 2.12(j),

the Effective Time), compensable time or pay, including salary, commission and
bonuses, personal time or pay or vacation time or vacation pay attributable to
service rendered on or prior to the Effective Time, the aggregate of which
exceeds $50,000 for any Significant Employee. Except as disclosed in ITEM
2.12(j) of the Powertel Letter and other than claims made in the ordinary course
of business consistent with past practice in an aggregate amount not to exceed
$500,000 neither Powertel nor any of the Powertel Subsidiaries have any
liability arising out of claims made or suits brought (including workers'
compensation claims and claims or suits for contribution to, or indemnification
of, third parties, occupational health and safety, environmental, consumer
protection or equal employment matters) for injury, sickness, disease,
discrimination, death or termination of employment of any Significant Employee,
or other employment matter to the extent attributable to an event occurring or a
state of facts existing on or prior to the Effective Time.

     (k) Except as set forth in ITEM 2.12(k) of the Powertel Letter, Powertel
and each of the Powertel Subsidiaries (i) is in compliance with all applicable
federal and state laws, rules and regulations respecting employment, employment
practices, terms and conditions of employment and wages and hours, in each

                                      C-14
<PAGE>   441

case, with respect to Powertel Employees, except where the failure to be in
compliance would not, singly or in the aggregate, have a Material Adverse Effect
on Powertel or its financial condition or business; (ii) has withheld all
amounts required by law or by agreement to be withheld from the wages, salaries
and other payments to Powertel Employees; (iii) is not liable for any arrears of
wages or any taxes or any penalty for failure to comply with any of the

Effect on Powertel; and (iv) (other than routine payments to be made in the
normal course of business and consistent with past practice) is not liable for

authority, with respect to unemployment compensation benefits, Social Security

     (l) Except as disclosed in ITEM 2.12(l) of the Powertel Letter, as of the
date of this Agreement there are no controversies, strikes, work stoppages or
disputes pending or to Powertel's knowledge threatened against Powertel or any
of the Powertel Subsidiaries, and no organizational effort by any labor union or
other collective bargaining unit currently is under way with respect to any
employee, which in any such case would reasonably be expected to have a Material
Adverse Effect on Powertel. None of Powertel or any of the Powertel Subsidiaries
is a party to a collective bargaining agreement. Except as set forth in ITEM
2.12(l) of the Powertel Letter, there is no, and there is not threatened, any
labor dispute, grievance or litigation relating to labor, safety or
discrimination matters involving any Powertel Employee including charges of
unfair labor practices or discrimination complaints, which, if adversely
determined, would reasonably be expected to have, individually or in the
aggregate, a Material Adverse Effect on Powertel. There has been no engagement
in any unfair labor practices by Powertel or the Powertel Subsidiaries within
the meaning of the National Labor Relations Act which would reasonably be
expected to have, individually or in the aggregate, a Material Adverse Effect on
Powertel.

Letter or in the Powertel Filed SEC Documents, as of the date of this Agreement,
there is no suit, action, proceeding or investigation pending or, to Powertel's

or materially delay the consummation of the Reorganization. Except as disclosed
in ITEM 2.13 of the Powertel Letter or in the Powertel Filed SEC Documents,

     SECTION 2.15  Section 203 of DGCL.  The Board of Directors of Powertel has
approved this Agreement, the Reorganization and the Powertel Stockholder
Agreement and the transactions contemplated hereby, with the effect that the
restrictions on business combinations contained in Section 203 of the DGCL will
not apply to VoiceStream or Sub as a result of this Agreement, the
Reorganization and Powertel Stockholder Agreement. To Powertel's knowledge, (i)
no anti-takeover statute or similar law of Georgia or Delaware imposes
restrictions which could reasonably be expected to adversely affect or delay the
consummation of the transactions contemplated by this Agreement, and (ii) no
"control share acquisition," "fair price," "moratorium" or other anti-takeover
laws or regulations enacted under Georgia or Delaware law applicable to Powertel
apply to this Agreement or any of the transactions related thereto.

     SECTION 2.16  Intellectual Property.  Except as set forth in the Powertel
Filed SEC Documents or in ITEM 2.16 of the Powertel Letter, the Intellectual
Property Rights consist solely of items and rights which are: (i) owned by
Powertel or the Powertel Subsidiaries; (ii) in the public domain; or (iii)
rightfully used by Powertel or the Powertel Subsidiaries pursuant to a license,
and, with respect to Intellectual Property Rights owned by Powertel or the
Powertel Subsidiaries, Powertel or the Powertel Subsidiaries own the entire
right, title and interest in and to such Intellectual Property Rights free and
clear of any Liens. Powertel and the Powertel Subsidiaries have all rights in
the Intellectual Property Rights necessary to carry out their businesses
substantially as currently conducted except as could not reasonably be expected
to have a Material Adverse Effect on Powertel. The Intellectual Property Rights
do not infringe on any proprietary right of any Person, except to the extent
that any such infringement, individually or in the aggregate, could not
reasonably be expected to have a Material Adverse Effect on Powertel. As of the
date of this Agreement, no claims against Powertel or any Powertel Subsidiary
(or, to Powertel's knowledge, against any other holder of Intellectual Property
Rights) (x) challenging the validity, effectiveness, or ownership by Powertel or
the Powertel Subsidiaries of any of the Intellectual Property Rights, or (y) to
the effect that the Intellectual Property Rights infringe or will infringe on
any intellectual property or other proprietary right of any Person have been
asserted or, to Powertel's knowledge, are threatened by any Person nor to
Powertel's knowledge are there any valid grounds for any bona fide claim of any
such kind. To Powertel's knowledge, there is no material unauthorized use,
infringement or misappropriation of any of the Intellectual Property Rights by
any third party, employee or former employee of Powertel or the Powertel
Subsidiaries.

     SECTION 2.17  Opinion of Financial Advisor.  The Board of Directors of
Powertel has received the oral opinion of Morgan Stanley & Co. Incorporated
("POWERTEL FINANCIAL ADVISOR"), on the date hereof, to the effect that, as of
the date hereof, the consideration to be received in the Reorganization by
Powertel's stockholders is fair to Powertel's stockholders from a financial
point of view.

     SECTION 2.18  Brokers.  Except for the Powertel Financial Advisor, the fees
and expenses of which will be paid by Powertel (and are reflected in an
agreement with Powertel, a true and correct copy of which has been furnished to
and accepted by VoiceStream), no broker, investment banker, financial advisor or
other person is entitled to any broker's, finder's, financial advisor's or other
similar fee or commission in connection with the transactions contemplated by
this Agreement based upon arrangements made by or on behalf of Powertel. In no
event shall the amounts paid or payable by Powertel to the Powertel Financial
Advisor in connection with the transactions contemplated by this Agreement
exceed $23,000,000.

     SECTION 2.19  Tax Status.  To the knowledge of Powertel after due
investigation, neither Powertel nor any of its Affiliates has taken any action
or failed to take any action which action or failure would jeopardize the
qualification of the Merger as a reorganization within the meaning of Section
368(a) of the Code. To the knowledge of Powertel after due investigation, there
are no facts or circumstances relating to Powertel or its Affiliates, including
any covenants or undertakings of Powertel pursuant to this Agreement, that would
prevent Morris, Manning & Martin, LLP from delivering the opinion referred to in
SECTION 6.02(b) as of the date hereof.

     SECTION 2.20  Contracts.  Except as set forth in the Powertel Filed SEC
Documents or in ITEM 2.20 of the Powertel Letter, and except for this Agreement,

                                      C-16
<PAGE>   443

agreements referenced hereby and thereby, neither Powertel nor any of the
Powertel Subsidiaries is a party to or bound by: (i) any "material contract" (as
such term is defined in Item 601(b)(10) of Regulation S-K of the SEC) or any
agreement, contract or commitment the loss or termination of which could have a
Material Adverse Effect on Powertel; (ii) any non-competition agreement or any
similar agreement or obligation which materially limits or could materially
limit Powertel or any of the Powertel Subsidiaries from engaging in the business
of providing wireless communications services or from developing wireless
communications technology anywhere in the world; or (iii) any management
agreement, technical services agreement or other agreement whereby Powertel or
any of the Powertel Subsidiaries is providing or is required to provide
management or technical services to any other Person. Taken as a whole, the
contracts and agreements required to be filed by Powertel with the SEC together
with the contracts and agreements required to be set forth on ITEM 2.20 of the
Powertel Letter are collectively referred to as the "POWERTEL CONTRACTS"). With
such exceptions as, individually or in the aggregate, have not had, and could
not be reasonably expected to have, a Material Adverse Effect on Powertel, (x)
each of the Powertel Contracts is valid and in full force and effect (except to
the extent they have previously expired in accordance with their terms), and (y)
except as set forth in ITEM 2.20 of the Powertel Letter, neither Powertel nor
any of the Powertel Subsidiaries has violated any provision of, or committed or
failed to perform any act which, with or without notice, lapse of time, or both,
would constitute a default under the provisions of any Powertel Contract. To the
knowledge of Powertel, no counterparty to any such contract, agreement or
commitment has violated any provision of, or committed or failed to perform any
act which, with or without notice, lapse of time, or both would constitute a
default or other breach under the provisions of, such Powertel Contract, except
for defaults or breaches which, individually or in the aggregate, have not had,
or would not reasonably be expected to have, a Material Adverse Effect on
Powertel. Neither Powertel nor any of the Powertel Subsidiaries is a party to,
or otherwise a guarantor of or liable with respect to, any interest rate,
currency or other swap or derivative transaction, other than any such
transactions which are not material to the business of Powertel or the Powertel
Subsidiaries. Powertel has provided or made available to VoiceStream a copy of
each agreement described in item (i), (ii) and (iii) above. The designation or
definition of Powertel Contracts for purposes of this SECTION 2.20 and the
disclosures made pursuant hereto shall not be construed or utilized to expand,
limit or define the terms "material" and "Material Adverse Effect" as otherwise
referenced and used in this Agreement.

     SECTION 2.21  Vote Required.  The only vote of the holders of any class or
series of capital stock of Powertel necessary to approve this Agreement and the
transactions contemplated hereby is the Powertel Stockholder Approval. As of the
date hereof, the Powertel Principal Stockholders have the requisite voting power
to satisfy the Powertel Stockholder Approval.

     SECTION 2.22  Transactions with Affiliates.  Except as described in ITEM
2.22 of the Powertel Letter or in the Powertel Filed SEC Documents, to
Powertel's knowledge, no director or executive officer of Powertel or any 5% or
greater stockholder of Powertel is at the date hereof a party to any transaction
with Powertel or any of the Powertel Subsidiaries in which the amount involved
exceeds $60,000, including any contract or arrangement providing for the
furnishing of services to or by, providing for rental of real or personal
property (including intellectual property) to or from, or otherwise requiring
payments to or from Powertel or any of the Powertel Subsidiaries.

                                  ARTICLE III

             REPRESENTATIONS AND WARRANTIES OF VOICESTREAM AND SUB

     Except as disclosed in the VoiceStream Filed SEC Documents and except as
set forth in the VoiceStream Letter (it being agreed that disclosure of any item
in the VoiceStream Letter shall be deemed disclosure with respect to any section
of this Agreement to which the relevance of such item is reasonably apparent),
(i) VoiceStream hereby represents and warrants as of the date hereof to Powertel
as

                                      C-17

follows, and (ii) Sub hereby represents and warrants as of September 28, 2000 to

     SECTION 3.01  Organization.  Each of VoiceStream and its Subsidiaries
(collectively, the "VOICESTREAM SUBSIDIARIES") is a corporation or limited
liability company and Sub is a corporation duly organized, validly existing and
in good standing (where such concept is applicable) under the laws of the
jurisdiction of its incorporation or organization and has the requisite power
and authority to carry on its business as now being conducted, except where the
failure to be so organized, existing and in good standing or to have such power
and authority could not reasonably be expected to have a Material Adverse Effect
on VoiceStream or prevent or materially delay the consummation of the
Reorganization. VoiceStream and Sub are duly qualified or licensed to do
business and are in good standing (where such concept is applicable) in each
jurisdiction in which the nature of their respective businesses or the ownership
or leasing of their respective properties makes such qualification or licensing
necessary, except in such jurisdictions where the failure to be so duly
qualified or licensed and in good standing (where such concept is applicable)
could not reasonably be expected to have a Material Adverse Effect on
VoiceStream or prevent or materially delay the consummation of the
Reorganization. VoiceStream has delivered to Powertel complete and correct
copies of its Certificate of Incorporation and By-laws and has made available to
Powertel the certificate of incorporation and by-laws (or similar organizational
documents) of each of the VoiceStream Subsidiaries.

     SECTION 3.02  Ownership of Sub.  All of the outstanding shares of capital
stock of Sub have been validly issued and are fully paid and nonassessable. All
of the outstanding shares of capital stock of Sub are owned by VoiceStream.

     SECTION 3.03  Capital Structure.  (a) The authorized capital stock of
VoiceStream consists solely of (i) 1,000,000,000 shares of VoiceStream Common
Stock, of which, as of July 31, 2000, (A) 214,617,441 shares were issued and

or the warrants described in the immediately preceding sentence, and (ii) as of
July 31, 2000, there are no outstanding VoiceStream Equity Rights. For purposes
of this Agreement, "VOICESTREAM EQUITY RIGHTS" means subscriptions, options,
warrants, calls, commitments, agreements, conversion rights, exchange rights or
other rights of any character (contingent or otherwise) to purchase or otherwise
acquire from VoiceStream or any of VoiceStream's Subsidiaries or any Cook Inlet
Joint Venture at any time any shares of the capital stock or other voting or
non-voting securities of VoiceStream. ITEM 3.03 of the VoiceStream Letter sets
forth a complete and accurate list of all outstanding VoiceStream Equity Rights
as of July 31, 2000 (provided that, with respect to options, such list need only
set forth the aggregate number of options with weighted-average exercise prices

owned by VoiceStream or one of the VoiceStream Subsidiaries free and clear of
any Liens except for Liens which are granted to secure indebtedness and are
disclosed in ITEM 3.03 of the VoiceStream Letter. Except as set forth on ITEM
3.03 of the VoiceStream Letter and as to the Exchange Rights, except as
hereafter issued or entered into in accordance with the DT Merger Agreement,
there are no material existing subscriptions, options, warrants, calls,
commitments, agreements, conversion rights, exchange rights or other rights of
any character (contingent or otherwise) to purchase or otherwise acquire from
VoiceStream or any VoiceStream Subsidiary or any Cook Inlet Joint Venture at any
time any shares of the capital stock or other voting or non-voting securities or

any Cook Inlet Joint Venture, whether or not presently issued or outstanding
(except for rights of first refusal to purchase interests in Subsidiaries which
are not wholly owned by VoiceStream and the Cook Inlet Joint Ventures), and
there are no outstanding obligations of VoiceStream or any of the VoiceStream
Subsidiaries or the Cook Inlet Joint Ventures to repurchase, redeem or otherwise

     SECTION 3.04  Authority.  The Board of Directors of VoiceStream, at a
meeting duly called and held, duly adopted resolutions (i) approving this
Agreement, the Reorganization, the Powertel Stockholder Agreements and the
VoiceStream Stockholder Agreements, (ii) determining that the Reorganization,
including the Merger, and the issuance of shares of VoiceStream Common Stock in
accordance with the Reorganization, is fair to and in the best interests of
VoiceStream stockholders and (iii) recommending that the VoiceStream
stockholders approve and adopt this Agreement. The Board of Directors of Sub has
declared the Reorganization advisable and approved this Agreement. VoiceStream
and Sub have the requisite corporate power and authority to execute and deliver
this Agreement and the other agreements to which they are parties, if any, that
are referenced herein and, subject, in the case of VoiceStream, to the approval
and adoption of this Agreement by a majority of the votes cast at a meeting by
the holders of the VoiceStream Common Stock and the VoiceStream Voting Preferred
Stock, voting together as a single class (the "VOICESTREAM STOCKHOLDER
APPROVAL"), to consummate the transactions contemplated hereby. The execution,
delivery and performance of this Agreement by VoiceStream and Sub and the
consummation by VoiceStream and Sub of the Reorganization and of the other
transactions contemplated hereby have been duly authorized by all necessary
corporate action on the part of VoiceStream and Sub, subject, in the case of
VoiceStream, to the VoiceStream Stockholder Approval. This Agreement has been
duly executed and delivered by VoiceStream and Sub and (assuming the valid
authorization, execution and delivery of this Agreement by Powertel) constitutes
the valid and binding obligation of each of VoiceStream and Sub enforceable
against each of them in accordance with its terms, except that such
enforceability (i) may be limited by bankruptcy, insolvency, reorganization,
moratorium or other similar laws affecting or relating to the enforcement of
creditors' rights and remedies generally and (ii) is subject to general
principles of equity (regardless of whether considered in a proceeding in equity
or at law). The

<PAGE>   446

issuance of shares of VoiceStream Common Stock in connection with the
Reorganization and the filing of a registration statement on Form S-4 with the
SEC by VoiceStream under the Securities Act for the purpose of registering the
shares of VoiceStream Common Stock to be issued in connection with the
Reorganization (together with any amendments or supplements thereto, whether
prior to or after the effective date thereof, the "REGISTRATION STATEMENT") have
been duly authorized by VoiceStream's Board of Directors.

     SECTION 3.05  Consents and Approvals; No Violations.  Except as set forth
in ITEM 3.05 of the VoiceStream Letter, and except for filings, permits,
authorizations, consents and approvals as may be required under, and other
applicable requirements of, the Securities Act, state securities or "Blue Sky"
laws, the Exchange Act, the Communications Act, the HSR Act, the DGCL, the
rules, regulations and published decisions of the FAA, the FCC and state public
utility or service commissions or similar agencies, or the rules and regulations
of Nasdaq (collectively, the "VOICESTREAM REQUIRED APPROVALS" and together with
the Powertel Required Approvals, the "REQUIRED REGULATORY APPROVALS"), neither
the execution, delivery or performance of this Agreement by VoiceStream and Sub
nor the consummation by VoiceStream and Sub of the transactions contemplated
hereby will (i) violate or conflict with the respective Certificate of
Incorporation or By-laws of VoiceStream and Sub, (ii) require any filing with,
or permit, authorization, consent or approval of, any Governmental Entity
(except where the failure to obtain such permits, authorizations, consents or
approvals or to make such filings could not reasonably be expected to have a
Material Adverse Effect on VoiceStream or prevent or materially delay the
consummation of the Reorganization), (iii) result in a violation or breach of,
or constitute (with or without due notice or lapse of time or both) a default
(or give rise to any right of termination, amendment, cancellation or
acceleration) under, any of the terms, conditions or provisions of any note,
bond, mortgage, indenture, license, lease, contract, agreement or other
instrument or obligation to which VoiceStream or any of the VoiceStream
Subsidiaries is a party or by which any of their respective properties are
bound, (iv) violate any order, writ, judgment, injunction, decree, statute, rule
or regulation applicable to VoiceStream or any of the VoiceStream Subsidiaries
or by which any of their respective properties are bound, or (v) result in the
creation or imposition of any Lien on any asset of VoiceStream or the
VoiceStream Subsidiaries, except in the case of clauses (iii), (iv) or (v) for
violations, breaches or defaults that could not reasonably be expected to have a
Material Adverse Effect on VoiceStream or prevent or materially delay the
consummation of the Reorganization.

     SECTION 3.06  SEC Documents and Other Reports.  VoiceStream has filed with
the SEC all documents required to be filed by it since January 1, 1999 under the
Securities Act or the Exchange Act (the "VOICESTREAM SEC DOCUMENTS"). As of
their respective filing dates, the VoiceStream SEC Documents were prepared
substantially in accordance with the requirements of the Securities Act or the
Exchange Act, as the case may be, each as in effect on the date so filed, and at
the time filed with the SEC (or if amended or superseded by a filing prior to
the date hereof, then on the date of such filing) none of the VoiceStream SEC
Documents contained any untrue statement of a material fact or omitted to state
a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading. The financial statements of VoiceStream included in the
VoiceStream SEC Documents have been prepared in accordance with generally
accepted accounting principles (except in the case of the unaudited statements,
under the Exchange Act) applied on a consistent basis during the periods
involved (except as may be indicated therein or in the notes thereto) and fairly
present the consolidated financial position of VoiceStream and the consolidated
VoiceStream Subsidiaries as of the respective dates thereof and the consolidated
results of operations and consolidated cash flows for the periods then ended
(subject, in the case of unaudited statements, to normal year-end audit
adjustments and to any other adjustments described therein).

     SECTION 3.07  Absence of Material Adverse Change.  Except as disclosed in
ITEM 3.07 of the VoiceStream Letter or in the documents filed by VoiceStream
with the SEC and publicly available prior to the date of this Agreement (the
"VOICESTREAM FILED SEC DOCUMENTS"), since December 31, 1999, VoiceStream and the
VoiceStream Subsidiaries have conducted their respective businesses in all
material respects only in the ordinary course, consistent with past practices,
and there has not been (i) any

                                      C-20
<PAGE>   447

Material Adverse Change with respect to VoiceStream, (ii) any declaration,
setting aside or payment of any dividend or other distribution with respect to
its capital stock (other than regular quarterly cash dividends) or any
redemption, purchase or other acquisition of any of its capital stock, (iii) any
split, combination or reclassification of any of its capital stock or any
issuance or the authorization of any issuance of any other securities in respect
of, in lieu of or in substitution for shares of its capital stock, or (iv) any
material change in accounting methods, principles or practices by VoiceStream
affecting its assets, liabilities or business, except insofar as may have been
required by a change in generally accepted accounting principles.

     SECTION 3.08  Information Supplied.  None of the information supplied or to
be supplied by VoiceStream specifically for inclusion or incorporation by
reference in (i) the Registration Statement or (ii) the Joint Proxy Statement,
will, in the case of the Registration Statement, at the time it becomes
effective, contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading, or in the case of the Joint Proxy Statement, at the time of the
first mailing of the Joint Proxy Statement or the time of the Stockholder
Meetings, contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they are made, not
misleading. The Registration Statement will comply (with respect to VoiceStream)
as to form in all material respects with the requirements of the Securities Act,
and the Joint Proxy Statement will comply (with respect to VoiceStream) as to
form in all material respects with the requirements of the Exchange Act.
VoiceStream makes no representation or warranty with respect to any information
supplied by Powertel or any other Person who is not an Affiliate of VoiceStream
which is contained in the Registration Statement or the Joint Proxy Statement.

     SECTION 3.09  Permits; Compliance with Laws.  (a) Each of VoiceStream and
the VoiceStream Subsidiaries is in possession of all franchises, grants,
authorizations, licenses, permits, charters, easements, variances, exceptions,
consents, certificates, approvals and orders of any Governmental Entity
necessary for VoiceStream or any of the VoiceStream Subsidiaries to own, lease
and operate its properties or to carry on its business as it is now being
conducted (the "VOICESTREAM PERMITS"), except where the failure to have any of
the VoiceStream Permits could not, individually or in the aggregate, have a
Material Adverse Effect on VoiceStream and, as of the date of this Agreement, no
suspension or cancellation of any of the VoiceStream Permits is pending or, to
the knowledge of VoiceStream, threatened, except where the suspension or
cancellation of any of the VoiceStream Permits could not reasonably be expected
to have, individually or in the aggregate, a Material Adverse Effect on
VoiceStream. The business of VoiceStream and the VoiceStream Subsidiaries is not
being conducted in violation of any law, ordinance or regulation of any
Governmental Entity, except for possible violations that could not reasonably be
expected to have a Material Adverse Effect on VoiceStream or prevent or
materially delay the consummation of the Reorganization.

     (b) Except as set forth in ITEM 3.09 of the VoiceStream Letter:

          (i) VoiceStream and each of the VoiceStream Subsidiaries holds, and is
     qualified and eligible to hold, all material licenses, permits and other
     authorizations issued or to be issued by the FCC to such entity for the
     operation of their respective businesses, all of which are set forth in
     ITEM 3.09 of the VoiceStream Letter (the "VOICESTREAM FCC LICENSES").

          (ii) The VoiceStream FCC Licenses are valid and in full force and
     effect, and neither VoiceStream nor any of the VoiceStream Subsidiaries is
     or has been delinquent in payment on or in default under any installment
     obligation owed to the United States Treasury in connection with the
     VoiceStream FCC Licenses. As used herein, the term "full force and effect"
     means that (A) the orders issuing the VoiceStream FCC Licenses have become
     effective, (B) no stay of effectiveness of such orders has been issued by
     the FCC, and (C) the VoiceStream FCC Licenses have not been invalidated by
     any subsequent published FCC action.

                                      C-21
<PAGE>   448

          (iii) All material reports and applications required by the
     Communications Act or required to be filed with the FCC by VoiceStream or
     any of the VoiceStream Subsidiaries have been filed and are accurate and
     complete in all material respects.

          (iv) VoiceStream and the VoiceStream Subsidiaries are, and have been,
     in compliance in all material respects with, and the wireless
     communications systems operated pursuant to the VoiceStream FCC Licenses
     are and have been operated in compliance in all material respects with, the
     Communications Act.

          (v) There is not pending or, to VoiceStream's knowledge, threatened,
     as of the date hereof any application, petition, objection, pleading or
     proceeding with the FCC or any public service commission or similar body
     having jurisdiction or authority over the communications operations of
     VoiceStream or any of the VoiceStream Subsidiaries which is reasonably
     likely to result in the revocation, cancellation, suspension, dismissal,
     denial or any materially adverse modification of any VoiceStream FCC
     License or imposition of any substantial fine or forfeiture against
     VoiceStream or any of the VoiceStream Subsidiaries.

          (vi) No facts are known to VoiceStream or the VoiceStream Subsidiaries
     which if known by a Governmental Entity of competent jurisdiction would
     present a substantial risk that any VoiceStream FCC License could be
     revoked, cancelled, suspended or materially adversely modified or that any
     substantial fine or forfeiture could be imposed against VoiceStream or any
     of the VoiceStream Subsidiaries.

          (vii) VoiceStream and the VoiceStream Subsidiaries have not made any
     material misstatements of fact, or omitted to disclose any fact, to any
     Government Entity or in any report, document or certificate filed
     therewith, which misstatements or omissions, individually or in the
     aggregate, could reasonably be expected to subject any material VoiceStream
     FCC Licenses to revocation or failure to renew, except to the extent that
     such revocation or failure to renew would not have a Material Adverse
     Effect on VoiceStream or the transactions contemplated by this Agreement.

     SECTION 3.10  Tax Matters.  Except as set forth in ITEM 3.10 of the
VoiceStream Letter or as would not have a Material Adverse Effect on

required to be filed by them either on a separate or combined or consolidated
basis; (ii) all such Tax Returns are correct in all respects and accurately
disclose in all respects all Taxes required to be paid for the periods covered
thereby; (iii) VoiceStream and the VoiceStream Subsidiaries have paid or caused
to be paid all Taxes shown as due on such Tax Returns and all Taxes for which no
Tax Return was required to be filed, and the financial statements contained in
the VoiceStream SEC Documents reflect an adequate reserve as determined in
accordance with generally acceptable accounting principles for all material
Taxes payable by VoiceStream and the VoiceStream Subsidiaries and not yet due
(other than a reserve for deferred Taxes established to reflect timing
differences between book and Tax treatment) for all taxable periods and portions
thereof accrued through the date of such financial statements; (iv) neither
VoiceStream nor any VoiceStream Subsidiary has waived in writing any statute of
limitations in respect of Taxes; (v) there is no action, suit, investigation,

duly withheld and collected, and have been paid or accrued on the books of
VoiceStream or such VoiceStream Subsidiary; (viii) none of VoiceStream or any
VoiceStream Subsidiary has been a member of any group of corporations filing Tax
Returns on a consolidated, combined, unitary or similar basis other than each
such group of which it is currently a member; (ix) no deduction of any amount
that would otherwise be deductible by VoiceStream or any of the VoiceStream
Subsidiaries with respect to taxable periods ending on or before the Effective
Time could be disallowed under Section 162(m) of the Code; and (x) neither

consolidated balance sheet of VoiceStream and the VoiceStream Subsidiaries or in
the notes thereto, other than (i) liabilities and obligations incurred in the
ordinary course of business since December 31, 1999 and (ii) liabilities arising

expected to have a Material Adverse Effect on VoiceStream.

     SECTION 3.13  State Takeover Statutes.  To the knowledge of VoiceStream, no
state antitakeover statute or similar statute or regulation applicable to
VoiceStream is applicable to this Agreement or the transactions contemplated
hereby. To the knowledge of VoiceStream, no other "control share acquisition,"

investigation, neither VoiceStream nor any of its Affiliates has taken any
action or failed to take any action which action or failure would jeopardize the
qualification of the Merger as a reorganization within the meaning of Section
368(a) of the Code. To the knowledge of VoiceStream after due investigation,
there are no facts or circumstances relating to VoiceStream or its Affiliates,
including any covenants or undertakings of VoiceStream pursuant to this
Agreement, that would prevent Jones, Day, Reavis & Pogue and/or Preston, Gates &
Ellis LLP from delivering the opinion referred to in SECTION 6.03(b) as of the
date hereof.

newly-formed single purpose corporation which has been formed solely for the
purpose of engaging in the transactions contemplated hereby, shall engage in no
other business or activities and shall have conducted its operations only as
contemplated hereby. VoiceStream shall have caused Sub to take all action
required pursuant to this Agreement prior to the Effective Time, including the
approval and adoption of this Agreement.

     SECTION 3.17  Vote Required.  The Merger requires the approval by
VoiceStream as the stockholder of Sub. The only vote required by the
stockholders of VoiceStream to approve this Agreement and the transactions
contemplated hereby is the VoiceStream Stockholder Approval.

     SECTION 3.18  Transactions with Affiliates.  Except as described in ITEM
3.18 of the VoiceStream Letter or the VoiceStream Filed SEC Documents, to
VoiceStream's knowledge, no director or executive officer of VoiceStream or any
5% or greater stockholder of VoiceStream is at the date hereof a party to any
transaction with VoiceStream or any of the VoiceStream Subsidiaries in which the
amount involved
                                      C-23

exceeds $60,000, including any contract or arrangement providing for the
furnishing of services to or by, providing for rental of real or personal
property (including intellectual property) to or from, or otherwise requiring
payments to or from VoiceStream or any of the VoiceStream Subsidiaries.

     SECTION 3.19  Opinion of Goldman, Sachs & Co.  The Board of Directors of
VoiceStream has received the oral opinion of Goldman, Sachs & Co. on the date
hereof, to the effect that, as of the date hereof, the Conversion Number

     or terminate any material contract or agreement to which Powertel or any of
     the Powertel Subsidiaries is a party, or waive, release or assign any

     SECTION 4.02  Conduct of Business by VoiceStream Pending the
Reorganization.  During the period from the date of this Agreement until the

          (a) amend the Certificate of Incorporation or the By-laws or the

     do any of the foregoing.

     SECTION 4.03  No Solicitation.

     (a) From and after the date hereof until the earlier of the Effective Time
or the termination of the Agreement, Powertel shall not, nor shall it permit any
of the Powertel Subsidiaries to, nor shall they authorize or permit any of their
respective officers, directors or employees to, and shall use their best efforts
to cause any investment banker, financial advisor, attorney, accountants or
other representatives retained by them or any of their respective Subsidiaries
not to, directly or indirectly through another Person, (i) solicit, initiate or
encourage (including by way of furnishing information), or knowingly take any
other action designed to facilitate, any Alternative Transaction (as defined
below), or (ii) continue or participate in any discussions or negotiations
regarding any Alternative Transaction; provided, however, that if, at any time
prior to the time that the Powertel Stockholders Approval is obtained, the Board
of Directors of Powertel receives an unsolicited bona fide proposal and
determines in good faith and after the receipt of advice from outside counsel
that providing information to the Third Party, making such proposal or
participating in negotiations or discussions with the Third Party is reasonably
likely to result in a Superior Proposal and if Powertel has fully and completely
complied with all its obligations under this SECTION 4.03, Powertel may, subject
to giving VoiceStream three (3) Business Days' advance written notice of its
intention to do so and obtaining a confidentiality agreement from the Third
Party substantially similar to the Confidentiality Agreement between Powertel
and VoiceStream dated as of March 9, 2000 (the "CONFIDENTIALITY AGREEMENT"), (x)
furnish information with respect to Powertel and the Powertel Subsidiaries, and
(y) engage in discussions and negotiations regarding such proposal.

     (b) Powertel will notify VoiceStream promptly (but in no event later than
24 hours) after receipt by Powertel (or any of its advisors) of any Alternative
Transaction, or of any request (other than in the ordinary course of business
and not related to an Alternative Transaction) for non-public information
relating to Powertel or any of the Powertel Subsidiaries or for access to the
properties, books or records of Powertel or any of the Powertel Subsidiaries by
any Person who is known to be considering making, or has

                                      C-27
<PAGE>   454

made, an Alternative Transaction. Powertel shall provide such notice orally and
in writing and shall identify the Person making, and the terms and conditions
of, any such Alternative Transaction or request. Powertel shall keep VoiceStream
fully informed, on a prompt basis (but in any event no later than 24 hours), of
the status and details of any such Alternative Transaction or request. Powertel
shall, and shall cause the Powertel Subsidiaries and the directors, employees
and other agents of Powertel and the Powertel Subsidiaries to, cease immediately
and cause to be terminated all activities, discussions or negotiations, if any,
with any Persons conducted prior to the date hereof with respect to any
Alternative Transaction.

     (c) Powertel (i) agrees not to release any Third Party from, or waive any
provision of, or fail to enforce, any standstill agreement or similar agreement
to which it is a party related to, or which could affect, an Alternative
Transaction and agrees that VoiceStream shall be entitled to enforce Powertel's
rights and remedies under and in connection with such agreements, and (ii)
acknowledges that the provisions of clause (i) are an important and integral
part of this Agreement. Nothing contained in this SECTION 4.03 or in SECTION
5.03 shall prohibit Powertel (x) from taking and disclosing to its stockholders
a position contemplated by Rule 14d-9 or Rule 14e-2(a) promulgated under the
Exchange Act, or (y) from making any disclosure to its stockholders if, in the
good faith judgment of the Board of Directors of Powertel, after receipt of
advice from outside counsel, failure to disclose would result in a reasonable
likelihood that the Board of Directors of Powertel would breach its duties to
Powertel's stockholders under Delaware law.

     (d) For purposes of this Agreement, "ALTERNATIVE TRANSACTION" means a
proposal or intended proposal, regarding any of (i) a transaction or series of
transactions pursuant to which any Person or "group" of Persons, other than
VoiceStream and its Subsidiaries (a "THIRD PARTY"), acquires or would acquire,
directly or indirectly, "beneficial ownership" (as such terms are defined in or
interpreted for purposes of Rule 13d-3 under the Exchange Act) of outstanding
shares representing more than twenty percent (20%) of the voting power of the
outstanding capital stock of Powertel or pursuant to a tender offer or exchange
offer or otherwise, (ii) any acquisition or proposed acquisition of, or business
combination with Powertel or any of the Powertel Subsidiaries, as applicable, by
a merger or other business combination (including any so-called
"merger-of-equals" and whether or not Powertel or any of the Powertel
Subsidiaries, as the case may be, is the entity surviving any such merger or
business combination), or (iii) any other transaction pursuant to which any
Third Party acquires or would acquire, directly or indirectly, control of assets
(including for this purpose the outstanding equity securities of the Powertel
Subsidiaries and any entity surviving the merger or business combination
including any of them) of Powertel or any of the Powertel Subsidiaries, as the
case may be, for consideration equal to twenty percent (20%) or more of the fair
market value of all of the outstanding shares of the Powertel capital stock on
the date of this Agreement; provided, that for purposes of this Agreement the
term "Alternative Transaction" does not include the Powertel Merger or the
Powertel Merger Agreement.

     SECTION 4.04  Disclosure of Certain Matters; Delivery of Certain
Filings.  Powertel shall promptly advise VoiceStream orally and in writing if
there occurs, to the knowledge of Powertel, any change or event which results in
the executive officers of Powertel having a good faith belief that such change
or event has resulted in or is reasonably likely to result in a Material Adverse
Effect on Powertel or that could reasonably be expected to prevent or materially
delay consummation of the Reorganization. VoiceStream shall promptly advise
Powertel orally and in writing if there occurs, to the knowledge of VoiceStream,
any change or event which results in the executive officers of VoiceStream
having a good faith belief that such change or event has resulted in or is
reasonably likely to result in a Material Adverse Effect on VoiceStream or that
could reasonably be expected to prevent or materially delay consummation of the
Reorganization. VoiceStream shall promptly provide to Powertel a copy of any
written notice given by VoiceStream to DT or received by VoiceStream from DT of
termination of the DT Merger Agreement. Powertel shall promptly provide to
VoiceStream, and VoiceStream shall promptly provide to Powertel, copies of all
filings made by Powertel or VoiceStream, as the case may be, with any
Governmental Entity in connection with this Agreement and the transactions
contemplated hereby and all notices and other communications and correspondence
from any Governmental Entity that relate to the Reorganization.

     SECTION 4.05  Tax Status.  During the period from the date of this
Agreement through the Effective Time, each of VoiceStream, Powertel and their
respective Affiliates shall use its reasonable best efforts (i) to cause the
Merger to qualify as a reorganization within the meaning of Section 368(a) of
the Code and (ii) to obtain the opinions of counsel referred to in SECTION
6.02(b) and SECTION 6.03(b), including the execution of the tax certificates
referenced therein.

     SECTION 4.06  Control of Operations.  Nothing contained in this Agreement
shall give VoiceStream, directly or indirectly, the right to "control" or
"direct," as such terms are construed under applicable rules or regulations of
the FCC, Powertel's operations prior to the Effective Time. Prior to the
Effective Time, Powertel shall exercise, consistent with the terms and
conditions of this Agreement, "control" over its respective operations.

     SECTION 4.07  Powertel Merger Agreement.  Powertel will not modify, amend
or waive in any material respect the provisions of the Powertel Merger Agreement
without VoiceStream's prior written consent.

                                   ARTICLE V

                             ADDITIONAL AGREEMENTS

     SECTION 5.01  Employee Benefits.

     (a) As of the Effective Time, Powertel will have terminated all Powertel
Benefit Plans except for those Powertel Benefit Plans that VoiceStream requests
not be terminated and those Powertel Benefit Plans described in ANNEX 5.18.
VoiceStream shall take all necessary action so that after the Effective Time,
any current or former employee of Powertel who is eligible to participate in a
Powertel Benefit Plan as of the Effective Time shall either be eligible to
continue his or her participation in such Powertel Benefit Plan or participate
in a corresponding employee benefit plan maintained by VoiceStream or any of its
Subsidiaries, subject to the terms of such corresponding plan. VoiceStream shall
have the sole discretion to determine which current or former employees of
Powertel will continue participation in a Powertel Benefit Plan after the
Effective Time and which will commence participation in a corresponding employee
benefit plan maintained by VoiceStream or any of its Subsidiaries after the
Effective Time and, with respect to current or former employees who transfer
participation to such a corresponding plan, when such transfer will occur.
VoiceStream need not treat all current and former employees of Powertel
(including those who are similarly situated) in the same manner with respect to
which plans they participate in and when, if at all, they transfer participation
from a Powertel Benefit Plan to a corresponding employee benefit plan maintained
by VoiceStream or any of its Subsidiaries. For example, VoiceStream may decide
to have a current or former employee of Powertel continue participation after
the Effective Time in certain Powertel Benefit Plans that have not been
terminated, and with respect to other benefits transition his participation on
or shortly after the Effective Time to a corresponding employee benefit plan
maintained by VoiceStream or one of its Subsidiaries. VoiceStream may take such
actions (or cause its Subsidiaries or the Surviving Corporation to take such
actions) as are necessary or advisable to accomplish the foregoing, including,
without limitation, amending the eligibility provisions of plans of VoiceStream,
any of its Subsidiaries or the Surviving Corporation (including, without
limitation, Powertel Benefit Plans that are not terminated on or before the
Effective Time).

     (b) Except as otherwise provided in this SECTION 5.01, nothing in this
Agreement shall be interpreted as limiting the power of the Surviving
Corporation to amend or terminate any particular Powertel Benefit Plan or any
other particular employee benefit plan, program, agreement or policy or as
requiring the Surviving Corporation to offer to continue (other than as required
by its terms) any written employment contract or to continue the employment of
any specific person; provided, however, (1) that no such termination or
amendment may take away benefits or any other payments already accrued as of the
time of such termination or amendment without the consent of such person, except
as allowed by law, and (2) that nothing in this SECTION 5.01 shall be
interpreted as limiting or modifying any requirement in SECTION 5.18 or
provisions of ANNEX 5.18.

                                      C-29
<PAGE>   456

     (c) VoiceStream shall, or shall cause the Surviving Corporation to, (A)
waive all limitations, to the extent allowable under applicable law, as to
preexisting conditions, exclusions and waiting periods with respect to
participation and coverage requirements applicable to the current and former
employees of Powertel and its Subsidiaries under any welfare or fringe benefit
plan in which such employees and former employees may be eligible to participate
after the Effective Time (other than a Powertel Benefit Plan that is not
terminated on or before the Effective Time), other than limitations or waiting
periods that are in effect with respect to such employees and that have not been
satisfied under the corresponding welfare or fringe benefit plan maintained by
Powertel for such current and former employees prior to the Effective Time, (B)
provide each current and former employee with credit under any welfare plans in
which such employee or former employee becomes eligible to participate after the
Effective Time for any co-payments and deductibles paid by such current or
former employee for the then current plan year under the corresponding welfare
plans maintained by Powertel prior to the Effective Time, and (C) provide (to
the extent allowed by law and Treasury regulations applicable to tax-qualified
plans) each current and former employee with full credit for purposes of
eligibility, vesting, and determination of the level of benefits under any
employee benefit plans, policies, practices or arrangements maintained by
VoiceStream or any VoiceStream Subsidiary for such current or former employee's
service with Powertel or any Powertel Subsidiary to the same extent recognized
by Powertel immediately prior to the Effective Time.

     (d) Except as expressly contemplated under SECTION 5.02 of this Agreement,
neither Powertel nor any affiliate thereof shall, from the date hereof until the
Effective Time, without the prior express written consent of VoiceStream, make
any contribution, sale or other transfer of Powertel Stock or any other
"employer security" (as such term is defined in Section 407 of ERISA), whether
to satisfy a required obligation, to reimburse for expenses incurred, or
otherwise, to any Powertel Benefit Plan or to the Powertel stock fund (or any
other fund) under the Powertel 401(k) Profit Sharing Plan. Moreover, Powertel
shall, promptly after the date hereof, amend the Powertel 401(k) Profit Sharing
Plan (as amended and restated effective as of January 1, 1998, and further
amended August 23, 1999), (a) to require that all contributions, from whatever
source, be made in the form of cash and (b) to preclude the use of any present
or future Powertel 401(k) Profit Sharing Plan assets to purchase from Powertel
or any affiliate thereof shares of Powertel Stock or other "employer securities"
(as such term is defined in Section 407 of ERISA); it being understood, however,
that such amendment need not preclude the Powertel 401(k) Profit Sharing Plan
from purchasing Powertel Stock on the open market from any person or entity
other than Powertel or an affiliate thereof, nor require that shares of Powertel
Stock and units in the Powertel stock fund presently under the Powertel 401(k)
Profit Sharing Plan be sold or otherwise liquidated.

     SECTION 5.02  Options; Restricted Stock Awards.

     (a) Prior to the Effective Time, the Board of Directors of Powertel (or the
Stock Option Compensation Committee of the Board of Directors) shall adopt such
resolutions or shall take such other actions as may be required, with respect to
Powertel Stock Options and the Powertel Restricted Stock Plan, to specifically
approve the transactions contemplated by this SECTION 5.02.

     (b) At the Effective Time, each Powertel Stock Option which is outstanding
immediately prior to the Effective Time pursuant to any Powertel Stock Plan
shall become and represent an option to purchase the number of shares of
VoiceStream Common Stock (a "SUBSTITUTE OPTION") determined by multiplying the
number of shares of Powertel Common Stock subject to such Powertel Stock Option
immediately prior to the Effective Time by the Conversion Number, at an exercise
price per share of VoiceStream Common Stock (increased to the nearest whole
cent) equal to the exercise price per share of Powertel Common Stock subject to
such Powertel Stock Option immediately prior to the Effective Time divided by
the Conversion Number; provided, however, that in the case of any Powertel Stock
Option to which Section 421 of the Code applies by reason of its qualification
under Section 422 of the Code ("INCENTIVE STOCK OPTIONS"), the option price, the
number of shares purchasable pursuant to such option and the terms and
conditions of exercise of such option shall be determined in order to comply
with Section 424(a) of the Code. The parties intend that the assumption of
incentive stock options provided for under this SECTION 5.02 shall meet the
requirements of Section 424(a) of the Code, and this SECTION 5.02 shall be
                                      C-30
<PAGE>   457

interpreted in a manner consistent with such intent. All other terms and
conditions applicable to the Powertel Stock Options, including vesting, shall
remain unchanged with respect to the Substitute Options (except to the extent
that such terms and conditions may be altered in accordance with the applicable
Powertel Stock Option Plan or stock option agreements related thereto). No
fractional shares of VoiceStream Common Stock will be issued upon the exercise
of Substitute Options. In lieu of such issuance, the shares of VoiceStream
Common Stock issued pursuant to the terms of this Agreement shall be rounded to
the closest whole share of VoiceStream Common Stock. After the Effective Time,
except as otherwise provided in this SECTION 5.02, each Substitute Option shall
be exercisable upon the same terms and conditions as were applicable to the
related Powertel Stock Option immediately prior to the Effective Time, after
giving effect to the resolutions and other actions described in this SECTION
5.02. Not later than the Effective Time, VoiceStream shall file a registration
statement on Form S-8 with respect to or otherwise include in an existing
registration statement the shares of VoiceStream Common Stock to be issued upon
exercise of the Substitute Options and shall use its reasonable best efforts to
maintain the effectiveness of such registration statement for so long as the
Substitute Options shall remain outstanding.

     (c) At the Effective Time, the Powertel Restricted Stock Plan shall
terminate and any unvested Powertel Restricted Stock Awards shall become fully
vested, except as otherwise provided in the applicable agreements relating to
such Powertel Restricted Stock Awards.

     SECTION 5.03  Stockholders Meetings.

     (a) As promptly as practicable after the Registration Statement is declared
effective under the Securities Act, Powertel shall duly give notice of, convene
and hold a meeting of its stockholders (the "POWERTEL STOCKHOLDERS MEETING") in
accordance with Delaware law for the purpose of obtaining the Powertel
Stockholder Approval and shall, subject to the provisions of SECTION 5.03(d)
hereof, through its Board of Directors, recommend to its stockholders the
approval and adoption of this Agreement, the Merger and the other transactions
contemplated hereby and shall use its reasonable best efforts to obtain the
Powertel Stockholder Approval.

     (b) As promptly as practicable after the Registration Statement is declared
effective under the Securities Act, VoiceStream shall duly give notice of,
convene and hold a meeting of its stockholders (the "VOICESTREAM STOCKHOLDERS
MEETING") in accordance with the DGCL for the purpose of obtaining the
VoiceStream Stockholder Approval and shall, through its Board of Directors,
recommend to its stockholders the approval and adoption of this Agreement and
shall use its reasonable best efforts to obtain the VoiceStream Stockholder
Approval.

     (c) Powertel and VoiceStream shall coordinate and cooperate with respect to
the timing of the Stockholder Meetings and shall use their reasonable best
efforts to hold such meetings on the same day.

     (d) Neither the Board of Directors of Powertel nor any committee thereof
shall (i) except as expressly permitted by this SECTION 5.03(d), withdraw,
qualify or modify, or propose publicly to withdraw, qualify or modify, in a
manner adverse to VoiceStream, the approval or recommendation of such Board of
Directors or such committee of this Agreement, the Merger and the other
transactions contemplated hereby, (ii) approve or recommend, or propose publicly
to approve or recommend, any Alternative Transaction, or (iii) cause Powertel to
enter into any letter of intent, agreement in principle, acquisition agreement
or other similar agreement related to any Alternative Transaction.
Notwithstanding the foregoing, in the event that prior to the time the Powertel
Stockholder Approval is obtained, Powertel receives a Superior Proposal (as
defined below), the Board of Directors of Powertel may (subject to this and the
following sentences) inform the Powertel stockholders that it no longer
recommends adoption and approval of this Agreement by the Powertel's
stockholders (a "SUBSEQUENT DETERMINATION"), but only at a time that is after
the fifth Business Day following VoiceStream's receipt of written notice
advising VoiceStream that the Board of Directors of Powertel has received a
Superior Proposal specifying the material terms and conditions of such Superior
Proposal (and including a copy or draft copy thereof with all accompanying
documentation or draft documentation, if in writing), identifying the Person
making such Superior Proposal and stating that it intends to make a Subsequent
Determination. After providing such notice, Powertel shall provide a reasonable
opportunity to VoiceStream to make such adjustments in the
                                      C-31
<PAGE>   458

terms and conditions of this Agreement as would enable Powertel to proceed with
its recommendation to its stockholders without a Subsequent Determination;
provided, however, that any such adjustment shall be at the discretion of
Powertel and VoiceStream at the time. For purposes of this Agreement, a
"SUPERIOR PROPOSAL" means any proposal (on its most recently amended or modified
terms, if amended or modified) made by a Third Party to enter into an
Alternative Transaction which the Board of Directors of Powertel determines in
its good faith judgment (based on, among other things, the advice of a financial
advisor of nationally recognized reputation) to be more favorable to the
Powertel's stockholders than the transactions contemplated by this Agreement
taking into account all relevant factors (including whether, in the good faith
judgment of the Board of Directors of Powertel, after obtaining the advice of a
financial advisor of nationally recognized reputation, the Third Party is
reasonably able to finance the transaction, and any proposed changes to this
Agreement that may be proposed by VoiceStream in response to such Alternative
Transaction). Powertel shall submit this Agreement to its stockholders at the
Powertel Stockholders Meeting even if the Board of Directors of Powertel shall
have made a Subsequent Determination.

     SECTION 5.04  Preparation of the Registration Statement and Joint Proxy
Statement.  As promptly as reasonably practicable following the date of this
Agreement, Powertel and VoiceStream shall prepare and file with the SEC the
Joint Proxy Statement and VoiceStream shall prepare and file with the SEC the
Registration Statement, in which the Joint Proxy Statement will be included as a
prospectus. VoiceStream shall use its reasonable best efforts, with the
cooperation and assistance of Powertel, to have the Registration Statement
declared effective under the Securities Act as promptly as practicable after
such filing and to keep the Registration Statement effective as long as is
necessary to consummate the Reorganization and the transactions contemplated in
connection therewith. VoiceStream shall also take any reasonable action (other
than qualifying to do business in any jurisdiction in which it is now not so
qualified) required to be taken under any applicable state securities laws in
connection with the issuance of VoiceStream Common Stock, in connection with the
Reorganization and upon any exercise of the Substitute Options. Powertel shall
furnish all information concerning Powertel and the holders of shares of
Powertel Stock as may be reasonably requested by VoiceStream in connection with
any such action. VoiceStream shall notify Powertel promptly of the receipt of
any comments from the SEC or its staff and of any request by the SEC or its
staff for amendments or supplements to the Registration Statement or the Joint
Proxy Statement or for additional information and will supply Powertel with
copies of all correspondence between VoiceStream or any of its representatives,
on the one hand, and the SEC or its staff, on the other hand, with respect to
the Registration Statement, the Joint Proxy Statement or the Reorganization. If
at any time prior to the Powertel Stockholders Meeting or the VoiceStream
Stockholders Meeting there shall occur any event that should be set forth in an
amendment or supplement to the Registration Statement or the Joint Proxy
Statement, each of VoiceStream and Powertel shall promptly prepare and mail to
the stockholders of Powertel and VoiceStream such an amendment or supplement.
VoiceStream and Powertel shall cooperate with one another and with DT in the
preparation of the Registration Statement, the DT Registration Statement, the
Joint Proxy Statement or any amendment or supplement thereto and in having the
Registration Statement, the DT Registration Statement and the Joint Proxy
Statement declared effective as soon as practicable.

     SECTION 5.05  Notification of Receipt of Proxy.

     (a) Promptly upon receipt by Powertel from any Powertel stockholder who is
a party to the Powertel Stockholder Agreement of a proxy card sent to the
Powertel stockholders with the Joint Proxy Statement and in accordance with the
Powertel Stockholder Agreement, but in no event later than the second Business
Day following such receipt or, if such receipt is on or after the fifth Business
Day prior to the Closing, then on the date of such receipt, Powertel shall
notify VoiceStream orally of its receipt and provide VoiceStream with a copy of
such proxy card.

     (b) Promptly upon receipt by VoiceStream from any VoiceStream stockholder
who is a party to a VoiceStream Stockholder Agreement of a proxy card sent to
the VoiceStream Stockholders with the Joint Proxy Statement and in accordance
with such VoiceStream Stockholder Agreement, but in no event later than the
second Business Day following such receipt or, if such receipt is on or after
the fifth Business

                                      C-32
<PAGE>   459

Day prior to the Closing, then on such date of receipt, VoiceStream shall notify
Powertel orally of its receipt and provide Powertel with a copy of such proxy
card.

     SECTION 5.06  Comfort Letters.

     (a) Powertel shall have received a "comfort" letter of Arthur Andersen LLP,
Powertel's independent public accountants, dated a date within two (2) business
days prior to the date of the first mailing of the Joint Proxy Statement,
addressed to Powertel, in form and substance reasonably satisfactory to Powertel
and as is reasonably customary in scope and substance for letters delivered by
independent public accountants in connection with registration statements on
Form S-4 with respect to the financial statements of VoiceStream included in the
Joint Proxy Statement and the Registration Statement.

     (b) VoiceStream shall have received a "comfort" letter of Arthur Andersen
LLP, VoiceStream's independent public accountants, dated a date within two (2)
business days prior to the date of the first mailing of the Joint Proxy
Statement, addressed to VoiceStream, in form and substance reasonably
satisfactory to VoiceStream and as is reasonably customary in scope and
substance for letters delivered by independent public accountants in connection
with registration statements on Form S-4 with respect to the financial
statements of Powertel included in the Joint Proxy Statement and the
Registration Statement.

     SECTION 5.07  Access to Information.  Upon reasonable notice and subject to
restrictions contained in the Confidentiality Agreement and other
confidentiality agreements to which Powertel is subject, (a) Powertel shall, and
shall cause each Powertel Subsidiary to, afford to VoiceStream and to the
officers, employees, accountants, counsel and other representatives of
VoiceStream all reasonable access, during normal business hours during the
period prior to the Effective Time, to all their respective lenders, agents and
other representatives, properties, assets, books, contracts, commitments and
records and, during such period, Powertel shall (and shall cause each Powertel
Subsidiary to) furnish promptly to VoiceStream all information concerning its
business, properties and personnel as VoiceStream may reasonably request,
including a copy of each report, schedule, registration statement and other
document filed or received by it during such period pursuant to the requirements
of the federal or state securities laws or the federal Tax laws and (b)
VoiceStream shall, and shall cause each VoiceStream Subsidiary to, afford to
Powertel and to the officers, employees, accountants, counsel and other
representatives of Powertel all reasonable access, during normal business hours
during the period prior to the Effective Time, to all their respective
properties, assets, books, contracts, commitments and records and, during such
period, VoiceStream shall (and shall cause each VoiceStream Subsidiary to)
furnish promptly to Powertel all information concerning its business, properties
and personnel as Powertel may reasonably request, including a copy of each
report, schedule, registration statement and other document filed or received by
it during such period pursuant to the requirements of the federal or state
securities laws.

     SECTION 5.08  Compliance with the Securities Act.

     (a) No later than thirty (30) days following the date of this Agreement,
Powertel shall cause to be prepared and delivered to VoiceStream a list
identifying all persons who, at the time of the Powertel Stockholders Meeting,
may be deemed to be an "affiliate" of Powertel, as such term is used in
paragraphs (c) and (d) of Rule 145 under the Securities Act (the "RULE 145
AFFILIATES"). Powertel shall use reasonable efforts to cause each person who is
identified as a Rule 145 Affiliate in such list to deliver to VoiceStream on or
prior to the Effective Time a written agreement, in the form attached hereto as
ANNEX C, that such Rule 145 Affiliate shall not sell, pledge, transfer or
otherwise dispose of any shares of VoiceStream Common Stock issued to such Rule
145 Affiliate in connection with the Reorganization, except pursuant to an
effective registration statement or in compliance with such Rule 145 or another
exemption from the registration requirements of the Securities Act.

     (b) Prior to the Effective Time, the Board of Directors of VoiceStream (or
the committee of the Board of Directors of VoiceStream composed solely of two
(2) or more "Non-Employee Directors," as that term is defined in Rule
16b-3(b)(3)(i) under the Exchange Act, administering the stock plans of
VoiceStream) shall adopt such resolutions or shall take such other actions as
are required to specifically approve the acquisitions of VoiceStream Common
Stock and Substitute Options at the Effective Time, as

                                      C-33
<PAGE>   460

contemplated by SECTIONS 1.06(c) and 5.02, by directors, officers or employees
of Powertel who may become directors or officers of VoiceStream, such approvals
to be given for the purpose of exempting such acquisitions under Rule 16b-3
under the Exchange Act, it being acknowledged that such approvals shall not
adversely affect VoiceStream's ability subsequently to determine that any such
person has not in fact become a director or officer of VoiceStream.

     SECTION 5.09  Nasdaq Listings.  VoiceStream shall use reasonable best
efforts to be included on Nasdaq, upon notification of issuance, the shares of
VoiceStream Common Stock to be issued in connection with the Reorganization and
upon any exercise of the Substitute Options.

     SECTION 5.10  Fees and Expenses.

     (a) Except as provided below in this SECTION 5.10 or SECTION 5.14, all fees
and expenses incurred in connection with the Reorganization, this Agreement and
the transactions contemplated hereby shall be paid by the party incurring such
fees or expenses, whether or not the Reorganization is consummated, except that
the costs and expenses, other than attorneys' fees, incurred in connection with
(i) the printing and mailing of the Joint Proxy Statement with respect to the
Reorganization, the DT Merger and the Powertel Merger, the Registration
Statement, the DT Registration Statement and the Powertel Registration Statement
(and any amendment or supplement thereto) and any prospectus included in such
registration statements (and any amendment or supplement thereto) shall be borne
one-third by VoiceStream, one-third by DT and one-third by Powertel, and (ii)
any filing fees (including fees payable to the SEC and state regulatory
authorities) with respect to the Joint Proxy Statement and the Registration
Statement shall be borne one-half by VoiceStream and one-half by Powertel.

     (b) In the event that VoiceStream terminates this Agreement pursuant to
SECTION 7.01(c)(i), SECTION 7.01(c)(ii) or SECTION 7.01(e)(ii) or Powertel
terminates this Agreement pursuant to SECTION 7.01(d)(ii), Powertel shall pay,
or cause to be paid, in same day funds to VoiceStream within one (1) Business
Day of such termination, $150,000,000 plus expenses not to exceed $10,000,000
(the "TERMINATION FEE"); provided that, in the event a termination fee is also
payable by Powertel in connection with the termination of the Powertel Merger
Agreement, Powertel shall pay each of DT and VoiceStream $75,000,000, plus
expenses not to exceed $10,000,000 in the aggregate.

     (c) In the event that Powertel terminates this Agreement pursuant to
SECTION 7.01(d)(i), SECTION 7.01(d)(iii) or SECTION 7.01(e)(i), VoiceStream
shall pay, or cause to be paid, the Termination Fee to Powertel in same day
funds within one (1) Business Day following such termination of this Agreement.

     (d) Powertel and VoiceStream agree that the agreements contained in SECTION
5.10(b) and SECTION 5.10(c) above are an integral part of the transactions
contemplated by this Agreement and are an inducement to VoiceStream and Powertel
to enter into this Agreement. If Powertel fails to promptly pay to VoiceStream
any fee due under such SECTION 5.10(b), or if VoiceStream fails to promptly pay
Powertel any fee due under SECTION 5.10(c), then the non-paying party shall pay
the costs and expenses (including legal fees and expenses) of the other party in
connection with any action, including the filing of any lawsuit or other legal
action, taken to collect payment, together with interest on the amount of any
unpaid fee at the publicly announced prime rate of Citibank, N.A., from the date
such fee was required to be paid.

     SECTION 5.11  Public Announcements.  VoiceStream and Powertel will consult
with each other and with DT before issuing any press release with respect to the
transactions contemplated by this Agreement and shall not issue any such press
release prior to such consultation, except as may be required by applicable law,
fiduciary duties or by obligations pursuant to any listing agreement with any
national securities exchange. The parties will cooperate in preparing a joint
press release announcing the execution of this Agreement.

     SECTION 5.12  State Takeover Laws.  If any "fair price" or "control share
acquisition" statute or other similar statute or regulation shall become
applicable to the transactions contemplated hereby, VoiceStream and Powertel and
their respective Boards of Directors shall use reasonable best efforts to
                                      C-34
<PAGE>   461

grant such approvals and take such actions as are necessary so that the
transactions contemplated hereby may be consummated as promptly as practicable
on the terms contemplated hereby and otherwise act to minimize the effects of
any such statute or regulation on the transactions contemplated hereby.

     SECTION 5.13  Indemnification; Directors and Officers Insurance.

     (a) VoiceStream shall, or shall cause the Surviving Corporation to,
continue to provide, fulfill and honor all rights to indemnification or
exculpation existing in favor of a director, officer, employee or agent (an
"INDEMNIFIED PERSON") of Powertel or any of the Powertel Subsidiaries (including
rights relating to advancement of expenses and indemnification rights to which
such persons are entitled because they are serving as a director, officer, agent
or employee of another entity at the request of Powertel or any of the Powertel
Subsidiaries), as provided in the Restated Certificate of Incorporation of
Powertel, the Restated By-laws of Powertel or any indemnification agreement, in
each case, as in effect on the date of this Agreement, and relating to actions
or events through the Effective Time, and such rights to indemnification shall
survive the Reorganization and shall continue in full force and effect, without
any amendment thereto; provided, however, that neither VoiceStream nor the
Surviving Corporation shall be required to indemnify any Indemnified Person in
connection with any proceeding (or portion thereof) to the extent involving any
claim initiated by such Indemnified Person unless the initiation of such
proceeding (or portion thereof) was authorized by the Board of Directors of
Powertel or unless such proceeding is brought by an Indemnified Person to
enforce rights under this SECTION 5.13; provided further that any determination
required to be made with respect to whether an Indemnified Person's conduct
complies with the standards set forth under the DGCL, the Restated Certificate
of Incorporation of Powertel, the Restated By-laws of Powertel or any such
agreement, as the case may be, shall be made by independent legal counsel
selected by VoiceStream and reasonably acceptable to such Indemnified Person;
provided further that VoiceStream and the Surviving Corporation will cooperate
and use all reasonable efforts to assist in the vigorous defense of any such
matter; and provided further that nothing in this SECTION 5.13 shall impair any
rights of any Indemnified Person. Without limiting the generality of the
preceding sentence, in the event that any Indemnified Person becomes involved in
any actual or threatened action, suit, claim, proceeding or investigation after
the Effective Time relating to actions prior to the Effective Time, VoiceStream
shall, or shall cause the Surviving Corporation to, promptly advance to such
Indemnified Person his or her legal and other expenses (including the cost of
any investigation and preparation incurred in connection therewith), subject to
the providing by such Indemnified Person, to the extent required by law, of an
undertaking to reimburse all amounts so advanced in the event of a non-
appealable determination of a court of competent jurisdiction that such
Indemnified Person is not entitled thereto.

     (b) Subject to the prior written approval by VoiceStream, which shall not
be unreasonably withheld, prior to the Effective Time, Powertel shall have the
right to obtain and pay for in full a "tail" coverage directors' and officers'
liability insurance policy ("D&O INSURANCE") covering a period of six (6) years
after the Effective Time and providing coverage in amounts and on terms
consistent with Powertel's existing D&O Insurance. In the event Powertel does
not obtain such insurance, VoiceStream shall cause the Surviving Corporation to
continue to provide D&O Insurance relating to actions or events through the
Effective Time, for a period of six (6) years after the Effective Time;
provided, that the Surviving Corporation may substitute therefor policies of
substantially similar coverage and amounts containing terms no less advantageous
to such former directors or officers; provided further that if the existing D&O
Insurance expires or is cancelled during such period, VoiceStream or the
Surviving Corporation shall make reasonable commercial efforts to obtain
substantially similar D&O Insurance; and provided further that Powertel shall
not be required to expend, in order to maintain or procure an annual D&O
Insurance policy, an amount in excess of 250% of the last annual premium paid
prior to the date hereof, but in such case shall purchase as much coverage as
possible for such amount.

     (c) In the event VoiceStream or the Surviving Corporation or any of their
respective successors or assigns (i) consolidates with or merges into any other
Person and shall not be the continuing or surviving corporation or entity of
such consolidation or merger or (ii) transfers all or substantially all of its
properties and assets to any Person in a single transaction or a series of
related transactions, then, and in
                                      C-35
<PAGE>   462

each such case, VoiceStream will make or cause to be made proper provision so
that the successors and assigns of VoiceStream or the Surviving Corporation, as
the case may be, assume the indemnification obligations described herein for the
benefit of the Indemnified Parties.

     (d) The provisions of this SECTION 5.13 are intended to be for the benefit
of, and shall be enforceable by, each Indemnified Person, his or her heirs and
his or her personal representatives and shall survive the Reorganization and be
binding upon the successors and assigns of VoiceStream, Powertel and the
Surviving Corporation.

     SECTION 5.14  Reasonable Best Efforts.

     (a) Subject to the provisions of this Agreement, each of Powertel,
VoiceStream and Sub agrees to use its reasonable best efforts to take, or cause
to be taken, all actions, and do, or cause to be done, and to assist and
cooperate with the other party or parties in doing, all things necessary, proper
or advisable, to consummate and make effective, in the most expeditious manner
practicable, the Reorganization and the other transactions contemplated by this
Agreement; provided, however, that neither VoiceStream nor any of the
VoiceStream Subsidiaries shall be required, nor, without the consent of
VoiceStream, shall Powertel or the Powertel Subsidiaries be permitted, to divest
or hold separate or otherwise take or commit to take any action that limits its
freedom of action with respect to Powertel, VoiceStream or any of their
respective Subsidiaries or any material portion of the assets of Powertel,
VoiceStream or any of their respective Subsidiaries or any of the business,
product lines, or assets of Powertel, VoiceStream or any of their respective
Subsidiaries. Without limiting the foregoing, (i) each of Powertel, VoiceStream
and Sub agrees to use its reasonable best efforts to take, or cause to be taken,
all actions necessary to comply promptly with all legal requirements that may be
imposed on itself or its Subsidiaries with respect to the Reorganization (which
actions shall include furnishing all information required under the HSR Act and
all actions required in connection with approvals of or filings with the FCC,
state public utility or service commissions or similar agencies and any other
Governmental Entity) and shall promptly cooperate with and furnish information
to each other in connection with any such requirements imposed upon any of them
or any of their Subsidiaries in connection with the Reorganization, (ii) each of
Powertel, VoiceStream and Sub shall, and shall cause its Subsidiaries to, use
its reasonable best efforts to obtain (and shall cooperate with each other in
obtaining) any consent, authorization, order or approval of, or any exemption
by, the FCC, state public utility or service commissions or similar agencies and
any other Governmental Entity or other public or private third party required to
be obtained or made by Powertel, VoiceStream, Sub or any of their Subsidiaries
in connection with the Reorganization or the taking of any action contemplated
thereby or by this Agreement, (iii) VoiceStream shall maintain Sub as a wholly-
owned VoiceStream Subsidiary, with no voting or approval rights outstanding
other than those held by VoiceStream, and VoiceStream shall cause Sub to
approve, and shall vote all securities and give all approvals necessary for Sub
to approve, the Reorganization, and (iv) each party will use its reasonable best
efforts to oppose entry or lift the effects of any injunction or other order
adversely affecting the ability of any party hereto to consummate the
transactions contemplated hereby to prevent, with respect to any threatened or
such injunction or other order, the issuance or entry thereto, provided however,
that notwithstanding anything to the contrary contained in this Agreement, in
connection with any filing or submission required or action to be taken by
VoiceStream, Powertel or any of their respective Subsidiaries to consummate the
Reorganization or the other transactions contemplated in this Agreement,
Powertel shall not, without VoiceStream's prior written consent, commit to any
divestiture of assets or businesses of Powertel and the Powertel Subsidiaries if
such divested assets and/or businesses are material to the assets or
profitability of Powertel and the Powertel Subsidiaries taken as a whole.

     (b) As promptly as practicable after the execution and delivery of this
Agreement, VoiceStream and Powertel shall prepare all appropriate applications
for FCC approval, and such other documents as may be required, with respect to
the transfer of control of Powertel to VoiceStream (collectively, the "FCC
APPLICATIONS"). Not later than the tenth Business Day following execution and
delivery of this Agreement, Powertel and VoiceStream will exchange with each
other their respective completed portions of the FCC Applications. Not later
than the fifteenth Business Day following the execution and delivery of this
Agreement, Powertel and VoiceStream shall file, or cause to be filed, the FCC
Applications. If the
                                      C-36
<PAGE>   463

Effective Time shall not have occurred for any reason within any applicable
initial consummation period, and neither Powertel nor VoiceStream shall have
terminated this Agreement pursuant to SECTION 7.01, VoiceStream and Powertel
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
Powertel. VoiceStream and Powertel shall each pay one-half (1/2) of any FCC
fees, if applicable, in connection with the filing or granting of approval of
the FCC Applications. Each of VoiceStream and Powertel shall bear its own
expenses in connection with the preparation and prosecution of the FCC
Applications. VoiceStream and Powertel shall each use all commercially
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

     transactions contemplated by this Agreement; provided, however, for
     purposes of this SECTION 6.02(a), the representations and warranties of

     and rely upon representations from others, including representations from

     not have been withdrawn or modified in any material respect.

     expected, individually or in the aggregate, to have a Material Adverse
     Effect on VoiceStream or upon the transactions contemplated by this
     Agreement.

          (d) FCC Opinion.  Powertel shall have received an opinion of FCC

     Material Adverse Effect on VoiceStream or the transactions contemplated by
     this Agreement, and such consents or authorizations shall not contain any
     conditions which would reasonably be expected to have a Material Adverse
     Effect on VoiceStream or the transactions contemplated by this Agreement.
     With respect to any FCC consents or authorizations, effectiveness of
     necessary FCC

<PAGE>   466

     approvals shall be sufficient to satisfy this condition, and Powertel's
     obligation to effect the Reorganization shall not be subject to the
     condition that any FCC consents or authorizations have become Final Orders.

     Notwithstanding anything contained to the contrary in SECTION 6.02(a) or
anywhere else in this Agreement, VoiceStream may enter into any Subsequent
Transaction, and no changes of any representation or warranty of VoiceStream
contained in this Agreement as a result of any Subsequent Transaction shall
result in a failure of the conditions set forth in SECTION 6.02(a); provided, in
each case, that any such Subsequent Transaction would not reasonably be expected
to have a Material Adverse Effect on VoiceStream.

     SECTION 6.03  Conditions to Obligations of VoiceStream and Sub to Effect

     particular date, in which case such representations and warranties shall be
     true and correct on and as of such particular date), in each case except as
     contemplated or permitted by this Agreement and except as would not,
     individually or in the aggregate, reasonably be expected to have a Material
     Adverse Effect on Powertel or VoiceStream or the transactions contemplated
     by this Agreement; provided, however, for purposes of this SECTION 6.03(a),
     the representations and warranties of Powertel shall be construed as if
     they did not contain any qualification that refers to Material Adverse
     Effect or materiality; and VoiceStream shall have received a certificate

     party, except where the failure to obtain the same would not reasonably be

     Effect on Powertel or VoiceStream or upon the transactions contemplated by
     this Agreement.

          (e) Governmental Approvals.  All necessary consents or authorizations

     requirement of finality is waived by VoiceStream in its sole discretion),

     have a Material Adverse Effect on Powertel or VoiceStream or the
     transactions contemplated by this Agreement, and such consents or
     authorizations shall not contain any conditions which would reasonably be
     expected to have a Material Adverse Effect on Powertel or VoiceStream or

     expected to have a Material Adverse Effect on Powertel or VoiceStream or
     the transactions contemplated by this Agreement, in each case which breach
     cannot be or has not been cured within 30 days after receipt by the
     breaching party of written notice of the breach; or

SECTION 5.10 or this SECTION 7.02; provided, however, that neither any provision

performance of any of the obligations or other acts of the other parties hereto,
(ii) waive any inaccuracies in the representations and warranties contained

Upon such determination that any term or other provision is invalid, illegal or
incapable of being enforced, the parties shall negotiate in good faith to modify

possible in a mutually acceptable manner in order that the transactions
contemplated by this Agreement may be consummated as originally contemplated to
the fullest extent possible.

     SECTION 8.09  Enforcement of this Agreement.  The parties hereto agree that
irreparable damage would occur in the event that any of the provisions of this
Agreement were not performed in accordance with their specific terms or were
otherwise breached in any material respect. It is accordingly agreed that the
parties shall be entitled to an injunction or injunctions to prevent breaches of
this Agreement or any related agreement and to enforce specifically the terms
and provisions of this Agreement or any related agreement in the Court of
Chancery of the State of Delaware or the Federal District Court for the District
of Delaware, this being in addition to any other remedy to which they are
entitled at law or in equity. In addition, each of the parties hereto (a)

nor any action brought pursuant to this SECTION 8.09, shall be interpreted as
providing an exclusive remedy to any party.

     SECTION 8.10  Obligations of Subsidiaries. Whenever this Agreement requires
any Powertel or VoiceStream Subsidiary (including Sub) to take any action, such
requirement shall be deemed to include an undertaking on the part of VoiceStream
or Powertel, as the case may be, to cause such Subsidiary to take such action.

     SECTION 8.11  Reliance on Representations.  Notwithstanding any
investigation, knowledge or review made at any time by or on behalf of any party
hereto, the parties acknowledge and agree that all representations and
warranties contained in this Agreement, the Annexes, the Powertel Letter, the
VoiceStream Letter or in any of the documents, certifications or agreements
delivered in connection therewith, are being relied upon as a material
inducement to enter into this Agreement and the transactions contemplated
hereby.

     SECTION 8.12  Failure or Indulgence Not Waiver; Remedies Cumulative.  No
failure or delay on the part of any party hereto in the exercise of any right
hereunder will impair such right or be construed to be a waiver of, or
acquiescence in, any breach of any representation, warranty or agreement herein,

further exercise thereof or of any other right. All rights and remedies existing
under this Agreement are cumulative to, and not exclusive to, and not exclusive
of, any rights or remedies otherwise available.

     SECTION 8.13  Rules of Construction.  The parties hereto agree that they

or rule of construction providing that ambiguities in an agreement or other
document will be construed against the party drafting such agreement or
document.

     SECTION 8.14  Date of this Agreement; No Waiver.  The amendment and
restatement of this Agreement on September 28, 2000 notwithstanding, unless
otherwise expressly provided herein, this Agreement shall be deemed for all
purposes to be dated and made as of August 26, 2000 (the date of the original

     The parties' execution and delivery of this Amended and Restated Agreement

Bellevue, WA 98006

Gentlemen and Madam:

     You have requested our opinion as to the fairness from a financial point of
view to the holders of the outstanding shares of Common Stock, par value $0.001
per share (the "Shares"), of VoiceStream Wireless Corporation ("VoiceStream" or
the "Company") of the Merger Consideration (as defined below) to be received by
such holders pursuant to the Agreement and Plan of Merger, dated as of July 23,
2000, between Deutsche Telekom AG ("DT") and the Company (the "Agreement").
Pursuant to the Agreement, a subsidiary of DT to be formed by DT will be merged
with and into the Company, and each outstanding Share not owned by DT or the
Company will be converted into, at the election of the holder of such Share,
either (i) 3.7647 ordinary shares of DT (the "DT Shares") as more fully set
forth in the Agreement; (ii) $200 in cash; or (iii) a combination of $30 in cash
and 3.2 DT Shares, in each case subject to certain procedures and limitations
contained in the Agreement including, without limitation, with respect to the
cash consideration to a maximum aggregate amount with respect to all Shares and
to the right of the Company to reduce such maximum aggregate amount as it
reasonably determines necessary to permit delivery of the requisite tax opinion
pursuant to the Agreement (collectively, the "Merger Consideration"), as to
which procedures and limitations we are expressing no opinion. Any stock
consideration payable pursuant to the Agreement to any holder of Shares will be
paid in the form of American Depositary Shares, each representing the right to
receive one DT Share, unless such holder elects to receive DT Shares in lieu of
such American Depositary Shares. In addition, pursuant to the Agreement, if the
volume weighted average per share trading prices of DT Shares on the Frankfurt
Stock Exchange for the seven Frankfurt Stock Exchange trading days randomly
selected by lot by DT and the Company together from the fifteen consecutive
Frankfurt Stock Exchange trading days ending on the date prior to the day on
which an adjustment to the aggregate cash consideration is to be made pursuant
to the Agreement is less than E33.00 per DT Share, the Company, but not DT, has
the right to terminate the Agreement. We also understand that the Agreement
contemplates the Company issuing to DT 3,906,250 shares of Convertible Voting
Preferred Stock, par value $0.001 per share, for aggregate consideration of
$5,000,000,000 pursuant to the Subscription Agreement (as defined below) prior
to the completion of the transaction contemplated by the Agreement.

     Goldman, Sachs & Co., as part of its investment banking business, is
continually engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, negotiated underwritings, competitive
biddings, secondary distributions of listed and unlisted securities, private
placements and valuations for estate, corporate and other purposes. We are
familiar with the Company having provided certain investment banking services to
the Company, its predecessor, VoiceStream Wireless Corporation, a Washington
Corporation ("VoiceStream Washington"), and its former parent, Western Wireless
Corporation ("Western"), from time to time, including having acted as lead
managing underwriter in the initial public offering of 12.65 million shares of
Western Common Stock in May 1996; having acted as lead manager in the public
offering of $200 million aggregate principal amount of 10.5% senior subordinated
notes due June 2006 of Western in May 1996; having acted as lead manager in the
private offering of $200 million aggregate principal amount of 10.5% senior
subordinated notes due February 2007 of Western in October 1996; having acted as
Western's financial advisor in connection with the sale of 19.9% of the
outstanding shares of VoiceStream Washington Common Stock to Hutchison PCS (USA)
Limited in February 1998; having acted as lead manager in the public offering of
13.915 million shares of Western Common Stock in April 1998; having acted as
financial advisor to VoiceStream in connection with its acquisition of Omnipoint
Corporation ("Omnipoint") in June 1999; having acted as
                                       D-1

financial advisor to VoiceStream in connection with its acquisition of Aerial
Communications, Inc. ("Aerial") in September 1999; having acted as co-manager in
the private offering of $1.1 billion aggregate principal amount of 10 3/8%
senior notes due November 2009 of VoiceStream Washington and the Company and
$720 million aggregate principal amount of 11 7/8% senior discount notes due
November 2009 of VoiceStream Washington and the Company in November 1999; and
having acted as its financial advisor in connection with, and having
participated in certain of the negotiations leading to, the Agreement.
Investment funds affiliated with Goldman, Sachs & Co. have a principal
investment in VoiceStream in the amount of 10,088,128 Shares and have the right
to designate a nominee for election to VoiceStream's Board of Directors. Terence
O'Toole, a Managing Director of Goldman, Sachs & Co., is a director of
VoiceStream. We have also provided, and are currently providing, significant
investment banking services to DT from time to time, including having acted as a
co-lead manager in the initial public offering of 714 million DT Shares in
November 1996; having acted as a co-lead manager in the public offering of 250
million DT Shares in June 1999; having acted as financial advisor to DT in the
acquisition of One 2 One Ltd. in July 1999; having acted as a co-lead manager in
the initial public offering of 114 million shares of T-Online (a subsidiary of

offering of 200 million DT Shares in June 2000; having acted as a co-lead
manager in the public offering of $14.6 billion aggregate principal amount of
notes (due at various maturity dates) of DT in June 2000, and may provide
investment banking services to DT in the future. Goldman, Sachs & Co. provides a
full range of financial advisory and securities services and, in the course of
its normal trading activities, may from time to time effect transactions and
hold securities, including derivative securities, of VoiceStream and DT for its
own account and for the accounts of customers. As of July 21, 2000, Goldman,
Sachs & Co. accumulated a net long position of 1,178,796 DT Shares. As of the
same date and in addition to the principal investment referred to above,
Goldman, Sachs & Co. had a net short position of 108,848 Shares.

     In connection with this opinion, we have reviewed, among other things, the
Agreement; the Stock Subscription Agreement, dated as of July 23, 2000 (the
"Subscription Agreement"), between the Company and DT; Annual Reports to
Stockholders and Annual Reports on Form 10-K of the Company (and its
predecessors) for the four years ended December 31, 1999; the definitive Proxy
Statement dated January 25, 2000 in connection with the acquisitions of
Omnipoint and Aerial; the Form 20-F of DT for the three years ended December 31,
1999; certain interim reports to stockholders of DT; certain interim reports to
stockholders and Quarterly Reports on Form 10-Q of the Company; the Registration
Statement on Form F-3 of DT, including the Prospectus dated June 17, 2000,
related to DT's offering of 200 million DT Shares; the Registration Statement on
Form F-3 of DT, including the Prospectus Supplement dated June 28, 2000, related
to DT's offering of $14.6 billion aggregate principal amount of notes; certain
other communications from the Company and DT to their respective stockholders;
and certain internal financial analyses and forecasts for the Company prepared
by its management. We also have held discussions with members of the senior
management of the Company and DT regarding their assessment of the strategic
rationale for, and the potential benefits of, the transaction contemplated by
the Agreement and the past and current business operations, financial condition
and future prospects of their respective companies. In addition, we have
reviewed the reported price and trading activity for the Shares and the DT
Shares, compared certain financial and stock market information for the Company
and DT with similar information for certain other companies the securities of
which are publicly traded, reviewed the financial terms of certain recent
business combinations in the telecommunications industry specifically and in
other industries generally and performed such other studies and analyses as we
considered appropriate.

     We have relied upon the accuracy and completeness of all of the financial
and other information discussed with or reviewed by us and have assumed such
accuracy and completeness for purposes of rendering this opinion. As you are
aware, DT did not make available to us its projections of expected future
financial performance. Accordingly, our review of such matters was limited to
discussions with
                                       D-2

members of the senior management of DT regarding certain research analyst
estimates of future financial performance of DT. In addition, we have not made
an independent evaluation or appraisal of the assets and liabilities of the
Company or DT or any of their subsidiaries and we have not been furnished with
any such evaluation or appraisal. We have also assumed that all material
governmental, regulatory or other consents and approvals necessary for the
consummation of the transaction contemplated by the Agreement will be obtained
without any adverse effect on the Company or DT or the contemplated benefits of
the transactions contemplated by the Agreement. Our advisory services and the
opinion expressed herein are provided for the information and assistance of the
Board of Directors of the Company in connection with its consideration of the
transaction contemplated by the Agreement and such opinion does not constitute a
recommendation as to how any holder of Shares should vote, or which election to
take, with respect to the Merger Consideration.

     Based upon and subject to the foregoing and based upon such other matters
as we consider relevant, it is our opinion that as of the date hereof the Merger
Consideration in aggregate to be received by the holders of Shares is fair from
a financial point of view to the holders of Shares.

                                          Very truly yours,

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

Gentlemen and Madam:

     You have requested our opinion as to the fairness from a financial point of
view to VoiceStream Wireless Corporation ("VoiceStream" or the "Company") of the
Conversion Number (as defined below) pursuant to the Agreement and Plan of
Reorganization, dated as of August 26, 2000, between Powertel, Inc. ("Powertel")
and the Company (the "VoiceStream Powertel Agreement"). Pursuant to the
VoiceStream Powertel Agreement, a subsidiary of VoiceStream to be formed by
VoiceStream will be merged (the "VoiceStream Powertel Merger") with and into
Powertel. We understand that VoiceStream has also entered into an Agreement and
Plan of Merger, dated as of July 23, 2000, between Deutsche Telekom AG ("DT")
and the Company (the "DT VoiceStream Agreement") pursuant to which a subsidiary
of DT to be formed by DT will be merged (the "DT VoiceStream Merger") with and
into the Company. We understand that DT has also entered into an Agreement and
Plan of Merger, dated as of August 26, 2000, between DT and Powertel (the "DT
Powertel Agreement") pursuant to which a subsidiary of DT to be formed by DT
will be merged (the "DT Powertel Merger") with and into Powertel. We understand
that pursuant to the terms of the VoiceStream Powertel Agreement, the
VoiceStream Powertel Agreement will automatically terminate concurrently with
the closing of the DT VoiceStream Merger (in which event the VoiceStream
Powertel Merger will not occur). We are not expressing any opinion herein with
respect to the DT Powertel Agreement, the DT Powertel Merger, the DT VoiceStream
Agreement or the DT VoiceStream Merger.

     Pursuant to the VoiceStream Powertel Agreement, upon consummation of the
VoiceStream Powertel Merger, each issued and outstanding share of Common Stock,
par value $0.01 per share (the "Powertel Common Stock"), of Powertel shall be
converted into a number of shares of Common Stock, par value $0.001 per share
(the "VoiceStream Common Stock"), of VoiceStream (the "Conversion Number") equal
to (i) 0.75 if the VoiceStream Average Closing Price (as defined below) is
$113.33 or below; (ii) 0.65 if the VoiceStream Average Closing Price is $130.77
or above; and (iii) if the VoiceStream Average Closing Price is greater than
$113.33 and less than $130.77, the quotient determined by dividing $85.00 by the
VoiceStream Average Closing Price, in each case subject to reduction in the
event that the aggregate number of outstanding shares of Powertel Common Stock
and securities convertible into or exchangeable for shares of Powertel Common
Stock as calculated pursuant to the VoiceStream Powertel Agreement exceeds the
number specified in the VoiceStream Powertel Agreement. Pursuant to the
VoiceStream Powertel Agreement, the "VoiceStream Average Closing Price" means
the volume weighted average closing price (based on the Nasdaq National Market
System ("Nasdaq") composite volume published by the Wall Street Journal) of the
VoiceStream Common Stock as publicly reported for Nasdaq as of 4:00 p.m. Eastern
Time for ten trading days randomly selected by lot out of the last twenty
trading days ending five trading days prior to the closing date of the
VoiceStream Powertel Merger. Also pursuant to the VoiceStream Powertel
Agreement, upon consummation of the VoiceStream Powertel Merger, each share of
Preferred Stock, par value $0.01 per share (the "Powertel Preferred Stock"), of
Powertel, whether or not such share is convertible by its terms as of the
effective time of the VoiceStream Powertel Merger, shall be converted into a
number of shares of VoiceStream Common Stock determined by multiplying (A) the
Conversion Number by (B) the sum of (1) the number of shares of Powertel Common
Stock into which such share of Powertel Preferred Stock would have been
converted as of the effective time of the VoiceStream Powertel Merger, if such
shares were then convertible and had been converted, plus

(2) with respect to any share of Series E 6.5% Cumulative Convertible Preferred
Stock of Powertel or any share of Series F 6.5% Cumulative Convertible Preferred
Stock of Powertel, the number of shares of Powertel Common Stock that represent
accrued or declared but unpaid dividends on any such share calculated as if the
closing date of the VoiceStream Powertel Merger were a dividend payment date.

Common Stock and have the right to designate a nominee for election to
VoiceStream's Board of Directors. Terence O'Toole, a Managing Director of
Goldman, Sachs & Co., is a director of VoiceStream. We have also provided
investment banking services in transactions involving Powertel from time to
time, including, through an affiliate, having purchased from Ericsson Inc.
("Ericsson"), in December 1997, $165 million aggregate principal amount of a
tranche of the loan made by Ericsson to Powertel (the "Ericsson Facility") and,
in June 1998, an additional $100 million aggregate principal amount of a tranche
of the Ericsson Facility, both tranches of which were subsequently syndicated to
other financial institutions. From time to time we have been a lender under the
Ericsson Facility and in that context, have been party to agreements with
respect to the Ericsson Facility. Goldman, Sachs & Co. provides a full range of
financial advisory and securities services and, in the course of its normal
trading activities, may from time to time effect transactions and hold
securities, including derivative securities, of VoiceStream and Powertel for its

Stock. As of the same date and in addition to the principal investment referred
to above, Goldman, Sachs & Co. had a net short position of 180,716 shares of

assessment of the strategic rationale for, and the potential benefits of, the

Company or Powertel or any of their subsidiaries and we have not been furnished
with any such evaluation or appraisal. We have also assumed that all material
governmental, regulatory or other consents and approvals necessary for the

recommendation as to how any holder of VoiceStream Common Stock should vote with
respect to such transaction.

     Based upon and subject to the foregoing and based upon such other matters
as we consider relevant, it is our opinion that as of the date hereof the
Conversion Number is fair from a financial point of view to VoiceStream.

                                          Very truly yours,

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

                     OPINION OF MORGAN STANLEY DEAN WITTER
                          VOICESTREAM/POWERTEL MERGER

                                                                 August 26, 2000

Board of Directors
Powertel, Inc.
1239 O.G. Skinner Drive
West Point, Georgia 31833

Members of the Board:

     We understand Powertel, Inc. ("Powertel" or the "Company") and Deutsche
Telekom AG ("DT") propose to enter into an Agreement and Plan of Merger,
substantially in the form of the execution draft dated August 26, 2000 (the
"Merger Agreement"), which provides, among other things, for the merger (the
"Merger") of a corporation to be formed as a wholly-owned subsidiary of DT with
and into Powertel. Pursuant to the Merger, Powertel will become a wholly-owned
subsidiary of DT and each outstanding share of common stock, par value $0.01 per
share, of Powertel (the "Powertel Common Stock"), other than shares owned by DT
or Powertel, shall be converted into the right to receive 2.6353 ordinary shares
of DT (the "DT Common Stock"), subject to adjustment in certain circumstances.
In addition, each share of Preferred Stock, par value $0.01 per share, of
Powertel (the "Powertel Preferred Stock") shall be converted directly into the
right to receive DT Common Stock pursuant to the ratios set forth in the Merger
Agreement, subject to adjustment in certain circumstances. The terms and
conditions of the Merger are more fully set forth in the Merger Agreement.

     As you know, VoiceStream Wireless Corporation ("VoiceStream") and DT
entered into an Agreement and Plan of Merger, dated as of July 23, 2000 (the
"VoiceStream Merger Agreement"), providing for the acquisition of VoiceStream by
DT (the "VoiceStream Merger"). We also understand that VoiceStream and Powertel
are entering into a separate merger agreement substantially in the form of the
execution draft dated August 26, 2000 (the "Alternative Merger Agreement"),
which provides for, among other things, the merger (the "Alternative Merger") of
a wholly owned subsidiary ("Alternative Sub") of VoiceStream with and into
Powertel in the event the VoiceStream Merger Agreement is terminated and the
VoiceStream Merger is not consummated. Pursuant to the Alternative Merger
Agreement, each outstanding share of Powertel Common Stock, other than shares
owned by Powertel or any subsidiary of Powertel or by VoiceStream, Alternative
Sub or any other subsidiary of VoiceStream, shall be converted into the right to
receive a certain number of shares of common stock, $0.001 par value, of
VoiceStream (the "VoiceStream Common Stock"), determined pursuant to the
formula(s) set forth in the Alternative Merger Agreement. In addition, each
share of Powertel Preferred Stock shall be converted directly into the right to
receive shares of VoiceStream Common Stock in accordance with the formula(s) set
forth in the Alternative Merger Agreement. The terms and conditions of the
Alternative Merger are more fully set forth in the Alternative Merger Agreement.
For the purposes of our opinion, we have assumed that each share of the Powertel
Preferred Stock has been converted into Powertel Common Stock immediately prior
to the consummation of the Merger or Alternative Merger. Our opinion does not
extend to the conversion terms of the Powertel Preferred Stock into Powertel
Common Stock.

     You have asked for our opinion as to whether (i) the consideration to be
received by the holders of shares of Powertel Common Stock and Powertel
Preferred Stock pursuant to the Merger Agreement is fair from a financial point
of view to holders of shares of the Powertel Common Stock and Powertel Preferred
Stock and (ii) in the event the VoiceStream Merger is not consummated, the
consideration to be received by the holders of shares of the Powertel Common
Stock and Powertel Preferred Stock pursuant to the Alternative Merger Agreement
is fair from a financial point of view to holders of shares of the Powertel
Common Stock and Powertel Preferred Stock.

     For purposes of the opinion set forth herein, we have:

          (i) reviewed certain publicly available financial statements and other
     information of Powertel, DT and VoiceStream;

          (ii) reviewed certain internal financial statements and other
     financial and operating data concerning Powertel, DT and VoiceStream
     prepared by the managements of Powertel, DT, and VoiceStream, respectively;

          (iii) analyzed certain financial projections prepared by the
     management of Powertel;

          (iv) analyzed certain financial projections for DT and VoiceStream
     contained in certain securities analysts' research reports that were
     recommended for review by the managements of DT and VoiceStream,
     respectively;

          (v) discussed the past and current operations and financial condition
     and the prospects of Powertel, including information relating to certain
     strategic, financial and operational benefits anticipated from each of the
     Merger and the Alternative Merger, with senior executives of Powertel;

          (vi) discussed the past and current operations and financial condition
     and the prospects of DT, including information relating to certain
     strategic, financial and operational benefits anticipated from the Merger
     with senior executives of DT;

          (vii) discussed the past and current operations and financial
     condition and the prospects of VoiceStream, including information relating
     to certain strategic, financial and operational benefits anticipated from
     the Alternative Merger with senior executives of VoiceStream;

          (viii) discussed the past and current operations and financial
     condition and the prospects of DT and VoiceStream, including information
     relating to certain strategic, financial and operational benefits
     anticipated from the VoiceStream Merger, with senior executives of DT and
     VoiceStream;

          (ix) reviewed the reported prices and trading activity for the
     Powertel Common Stock, the DT American Depositary Shares, each representing
     one right to receive one share of DT Common Stock (the "DT ADS's") and the
     VoiceStream Common Stock;

          (x) compared the financial performance of Powertel, DT and VoiceStream
     and the prices and trading activity of the Powertel Common Stock, the DT
     ADS's and the VoiceStream Common Stock with those of certain other
     publicly-traded companies comparable with Powertel, DT and VoiceStream
     respectively and their securities;

          (xi) reviewed the financial terms, to the extent publicly available,
     of certain comparable acquisition transactions;

          (xii) participated in discussions and negotiations among
     representatives of Powertel, DT and VoiceStream and their financial and
     legal advisors;

          (xiii) reviewed the terms, including the financial terms, of the
     Merger Agreement, the Alternative Merger Agreement and the VoiceStream
     Merger Agreement and certain related documents; and

          (xiv) performed such other analyses and considered such other factors
     as we have deemed appropriate.

     We have assumed and relied upon without independent verification the
accuracy and completeness of the information reviewed by us for the purposes of
this opinion. With respect to the financial projections, including information
relating to certain strategic, financial and operational benefits anticipated
from each of the Merger, the Alternative Merger and the VoiceStream Merger, we
have assumed they have been reasonably prepared on bases reflecting the best
currently available estimates and judgments of the future financial performance
of Powertel, DT, and VoiceStream. For the purposes of our analysis, we have
relied with your consent on the estimates of certain securities analysts'
research reports that were recommended

                                       F-2
<PAGE>   489

for review by the managements of DT and VoiceStream. Morgan Stanley & Co.
Incorporated has also assumed that the Alternative Merger will be consummated
only if the VoiceStream Merger is not consummated. In addition, we have assumed
the Merger will be consummated in accordance with the terms set forth in the
Merger Agreement, including that the Merger will be treated as a tax-free merger
and/or exchange pursuant to the Internal Revenue Code of 1986 (the "Code"), and
we have assumed that in the event the VoiceStream Merger is not consummated, the
Alternative Merger will be consummated in accordance with the terms set forth in
the Alternative Merger Agreement, including that the Alternative Merger will be
treated as a tax-free merger and/or exchange pursuant to the Code. Morgan
Stanley & Co. Incorporated has assumed that obtaining all necessary regulatory
approvals for the Merger or Alternative Merger will not have a material adverse
effect on Powertel, VoiceStream or DT or the financial, strategic and
operational benefits anticipated from the Merger or Alternative Merger. We have
not made any independent valuation or appraisal of the assets or liabilities of
Powertel, DT, or VoiceStream, nor have we been furnished with any such
appraisals. Our opinion is necessarily based on financial, economic, market and
other conditions as in effect on, and the information made available to us as
of, the date hereof.

     We have acted as financial advisor to the Board of Directors of Powertel in
connection with these related transactions and will receive a fee for our
services. In the past, Morgan Stanley & Co. Incorporated and its affiliates have
provided financial advisory services and financing services for Powertel and DT
and have received fees for the rendering of these services.

     It is understood this letter is for the information of the Board of
Directors of Powertel and may not be used for any other purpose without our
prior written consent, which consent will not be unreasonably withheld, except
this opinion may be included in its entirety in any filing made by Powertel in
respect of the Merger or Alternative Merger with the Securities and Exchange
Commission. In addition, this opinion does not in any manner address the prices
at which the Powertel Common Stock, the DT Common Stock or the VoiceStream
Common Stock will trade following the consummation of the Merger or Alternative
Merger, and Morgan Stanley & Co. Incorporated expresses no opinion or
recommendation as to how the holders of the Powertel Common Stock, holders of
the DT Common Stock or holders of the VoiceStream Common Stock should vote at
the shareholders' meetings held in connection with the Merger or Alternative
Merger. In addition, we express no opinion as to the relative values of the
consideration to be received by holders of shares of Powertel Common Stock and
Powertel Preferred Stock pursuant to the Merger Agreement and the consideration
to be received by holders of shares of the Powertel Common Stock and Powertel
Preferred Stock pursuant to the Alternative Merger Agreement.

     Based on and subject to the foregoing, we are of the opinion on the date
hereof that (i) the consideration to be received by holders of shares of
Powertel Common Stock and Powertel Preferred Stock pursuant to the Merger
Agreement is fair from a financial point of view to holders of shares of the
Powertel Common Stock and Powertel Preferred Stock and (ii) in the event the
VoiceStream Merger is not consummated, the consideration to be received by the
holders of shares of the Powertel Common Stock and Powertel Preferred Stock
pursuant to the Alternative Merger Agreement is fair from a financial point of
view to holders of shares of the Powertel Common Stock and Powertel Preferred
Stock.

                                          Very truly yours,

                                          MORGAN STANLEY & CO. INCORPORATED

      SECTION 262 OF THE GENERAL CORPORATION LAW OF THE STATE OF DELAWARE

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 nonstock 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 interdealer 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 subsections (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
        interdealer 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

             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.

                                       G-1
<PAGE>   491

          (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 subsection (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 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
                                       G-2
<PAGE>   492

     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.

     (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
                                       G-3
<PAGE>   493

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 is 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

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Deutsche Telekom has obtained customary liability insurance for members of
its supervisory board and its management board and certain of its officers. This
includes insurance against liabilities under the Securities Act.

     Under German law, a corporation may indemnify its officers, and, under
certain circumstances, German labor law requires a stock corporation to do so.
However, a corporation may not, as a general matter, indemnify members of the
management board or the supervisory board. In addition, German law may permit a
corporation to indemnify a member of the management board or the supervisory
board for attorneys' fees incurred if such member is the successful party in a
suit in a country, like the United States, where winning parties are required to
bear their own costs, if German law would have required the losing party to pay
the member's attorneys' fees had the suit been brought in Germany.

                securities offered would not exceed that which was registered)
                and any deviation from the low or high end of the estimated
                maximum offering range may be reflected in the form of
                prospectus filed with the Securities and Exchange Commission
                pursuant to Rule 424(b) if, in the aggregate, the changes in
                volume and price represent no more than 20 percent change in the
                maximum aggregate offering price set forth in the "Calculation
                of Registration Fee" table in the effective Registration
                Statement; and

           (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 will be
            deemed to be a new registration statement relating to

                                      II-5
<PAGE>   499

            the securities offered therein, and the offering of such securities
            at that time will 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.

        (4) To file a post-effective amendment to the Registration Statement to
            include any financial statements required by Item 8 of Form 20-F at
            the start of any delayed offering or throughout a continuous
            offering.

     (b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Exchange
Act that is incorporated by reference in the Registration Statement will be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time will 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.

         (2) The undersigned registrant hereby undertakes that every prospectus
(i) that is filed pursuant to paragraph (1) immediately preceding, or (ii) that
purports to meet the requirements of Section 10(a)(3) of the 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 will be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time will be deemed to be
the initial bona fide offering thereof.

     (d) 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 foregoing provisions, 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 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 Act and will be governed by the final adjudication of
such issue.

     (e) The undersigned registrant hereby undertakes: (1) to respond to
requests for information that is incorporated by reference into the prospectus
pursuant to Items 4, 10(b), 11 or 13 of this Form, within one business day of
receipt of such request, and to send the incorporated documents by first class
mail or other equally prompt means; and (2) to arrange or provide for a facility
in the United States for the purpose of responding to such requests. This
includes information contained in documents filed subsequent to the effective
date of the registration statement through the date of responding to the
request.

     (f) 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.
