                          STOCK RESTRICTION AGREEMENT

                  THIS STOCK RESTRICTION AGREEMENT (the "Agreement") made as of
the 24th day of February, 1997 (the "Effective Date"), between Omnipoint
Corporation, a Delaware corporation (the "Company"), and Kjell S. Andersson (the
"Employee").

                  For valuable consideration, receipt of which is acknowledged,
the parties hereto agree as follows:

                  1. Purchase of Shares. The Employee hereby subscribes for and,
                     ------------------
upon acceptance hereof, shall purchase, subject to the terms and conditions set
forth in this Agreement, 60,000 shares (the "Shares") of common stock, $.01 par
value, of the Company ("Common Stock"), at a purchase price per share equal to
$18.125 ("the Purchase Price"). In consideration of the receipt by the Employee
of the Shares, the Employee shall deliver to the Company a five-year Note in the
principal amount of $1,087,500 bearing interest at the rate of 6.6% per annum
(the "Note") payable to the Company. Principal and interest on the Note shall be
due and payable upon the earlier of February 24, 2002, or the termination of
Employee's employment. Upon receipt of the Note by the Company for the Shares,
the Company shall cause to be issued to the Employee a certificate in the name
of the Employee for the Shares. The Employee agrees that the Shares shall be
subject to the Purchase Option (as defined below) set forth in Section 2 of this
Agreement and the restrictions on transfer set forth in Section 5 of this
Agreement.

                  2. Purchase Option. Subject to the provisions of Paragraph 4,
                     ---------------
if the Employee ceases to be employed by the Company for any reason other than
for cause pursuant to Section 4.2 of the Employment Agreement between the
Employee and the Company dated February 24, 1997 (the "Employment Agreement"),
the Company shall have the right and option to purchase (the "Purchase Option")
from the Employee, for a sum of $18.125 per share (the "Option Price"), up to
that percentage of the Shares as is set forth in the second column of the table
set forth below opposite the period in which the Employee ceases to be so
employed.

                  3.  Exercise of Purchase Option and Closing.
                      ---------------------------------------

                  (a) The Company, or its designee, shall exercise the Purchase
Option granted to it by delivering or mailing to the Employee, in accordance
with Section 11, written notice of exercise within 90 days after the termination
of the employment of the Employee with the Company. Such notice shall specify
the number of Shares to be purchased. If and to the extent the Purchase Option
is not so exercised within such 90-day period, the Purchase Option shall
automatically expire and terminate effective upon the expiration of such 90-day
period.

                  (b) Subject to the provisions of Paragraph 4, within 10 days
after his receipt of the Company's or its designee's notice of the exercise of
the Purchase Option pursuant to subsection (a) above, the Employee (or his
estate) shall tender to the Company or its designee at its principal offices the
certificate or certificates representing the Shares that the Company or its
designee has elected to purchase, duly endorsed in blank by the Employee or with
duly endorsed stock powers attached thereto, all in form suitable for the
transfer of such Shares to the Company or its designee. Upon its receipt of such
Shares, the Company or its designee shall cancel such portion of the Employee's
indebtedness under the Note that relates to the repurchased Shares at the
aggregate Option Price for such shares.

                  (c) After the time at which any Shares are required to be
delivered to the Company or its designee for transfer to the Company or its
designee pursuant to subsection (b) above, the Company shall not pay any
dividend to the Employee on account of such Shares or permit the Employee to
exercise any of the privileges or rights of a stockholder with respect to such
Shares, but shall, in so far as permitted by law, treat the Company or its
designee as the owner of such Shares.

                  (d) The Company or its designee shall not purchase any
fraction of a Share upon exercise of the Purchase Option, and any fraction of a
Share resulting from a computation made pursuant to Section 2 of this Agreement
shall be rounded to the nearest whole Share (with any one-half Share being
rounded upward).

                  4.  Termination of Employment.
                      -------------------------

                  (a) Notwithstanding other provisions of this Agreement, if the
Employee is terminated without cause or leaves the Company for good reason, as
such term is defined in Section 4.5 of the Employment Agreement (such day the
Employee so terminates or leaves, the "Termination Date"), prior to the fifth
anniversary of this employment with the Company, the Employee will be entitled
to the following:

                      (i)   If the Equity Value, as determined below, is less
than $1,000,000 as of the Termination Date, and the Measurement Date, as defined
below, is such Termination Date, notwithstanding the provisions of Section 2
above, the Employee will be entitled to the retain such number of shares
remaining subject to the Purchase Option that together with the Owned Shares and
the Sold Shares, each defined below, would have an Equity Value of $1,000,000,
and the Company will repurchase the balance of the Shares in full settlement of
the Note.

                      (ii)  If the Equity Value is less than $1,000,000 as of
the Termination Date, the Company may delay the Measurement Date for satisfying
this requirement to any date it may fix on not less than ten (10) days written
notice on or before the fifth anniversary of the commencement of Employee's
employment. During such period, the Employee shall report to the Company any
shares that he sells and the proceeds received for them. In the event that, as a
result, (1) the Measurement Date is after the Company's exercise of its Purchase
Option and (2) the Equity Value as of such date is less than $1,000,000, the
Company shall, in its sole discretion and in full satisfaction of the Note,
either (a) issue to the Employee the lesser of (i) a number of shares having a
Fair Market Value equal to the difference or (ii) the number of shares
repurchased by the Company under the Purchase Option or (b) deliver to the
Employee cash for the amount of such difference.

                      (iii) If the Equity Value is greater than $1,000,000 as of
the Termination Date, the Employee will surrender the Shares subject to the
Purchase Option in full satisfaction of the Note.

                      (iv)  The Company shall select a date on which the Equity
Value of the Shares shall be determined, as set forth in this Section 4 (such
date, the "Measurement Date"). The Company may not select a Measurement Date
that is a date that is prior to the earlier of (A) the minimum holding period
requirement for the Shares as set forth in Rule 144 of the Securities Act, as
defined below (one year, effective April 29, 1997) or (B) the date on which a
registration statement filed with the Securities and Exchange Commission is
declared effective covering such number of Shares to which the Purchase Option
no longer applies.

                      (v)   The "Equity Value" will be determined by (a)
multiplying the closing price of the Common Stock on the Nasdaq National Market
(or any other market on which the shares trade) on the Measurement Date, or if
the Measurement Date is not a date on which the Nasdaq National Market is open,
the next such date (the "Fair Market Value"), by the number of shares of Common
Stock (i) held by the Employee and not subject to the Purchase

                                      -3-
<PAGE>

Option or (ii) issuable to the Employee upon exercise of vested options as of
the Measurement Date (all of such shares and options collectively, the "Owned
Shares") and (b) adding the product to the sum of the proceeds received by the
Employee from sales of shares of Common Stock (whether purchased directly or
upon the exercise of options) from the Commencement Date through the Measurement
Date (the "Sold Shares") and (c) subtracting cash amounts actually paid for
shares acquired upon exercise of options or required to be paid for the exercise
of vested unexercised options.

                  (b) If the Employee is terminated for cause, as defined in
Section 4.2 of the Employment Agreement, the Note plus accrued interest will be
immediately due and payable. The Employee's obligation to repay the outstanding
balance will be limited to the lesser of (i) the Option Price for the shares no
longer subject to the Purchase Option, or (ii) the Fair Market Value at the time
of termination of the Shares no longer subject to the Purchase Option that the
Employee still holds plus the proceeds of any Sold Shares.

                  (c) Should the Employee resign from the Company without good
reason, as defined in the Employment Agreement, prior to the first anniversary
of the Effective Date, the Employee shall pay to the Company any remaining
obligation under the Note should the Fair Market Value of the Shares remaining
subject to the Purchase Option be less than the principal balance of the Note
plus accrued interest, provided, however that the Employee's repayment
obligation shall not exceed the Fair Market Value of 10,000 shares of Common
Stock as of the date of the Employee's resignation without good reason. If the
Employee resigns without good reason after the first anniversary of the
Effective Date, the Shares remaining subject to the Purchase Option shall
satisfy the Employee's repayment obligations under the Note.

                  (d) If the Employee is terminated without cause or leaves with
good reason following a change of control of the Company, as defined below, or
if, following a change of control of the Company that is not approved by the
Board of Directors of the Company, the Employee either resigns with or without
good reason or is terminated without cause, no Shares shall remain subject to
the Purchase Option, and any outstanding amounts under the Note will be
forgiven. A "change of control" shall be deemed to occur upon the first of the
following events:

                      (i)   any person becomes the beneficial owner, directly or
indirectly, of securities of the Company representing 50% or more of the
combined voting power of the Company's then outstanding voting securities and
such person has the ability to elect a majority of the members of the Company's
Board of Directors, if such ownership is not in place on the date of grant;

                      (ii)  any person becomes the beneficial owner, directly or
indirectly, of securities of the Company sufficient to elect a majority of the
members of the Board of Directors of the Company, provided that the Employee's
responsibilities as an executive of the Company are materially adversely
diminished by such change in control; or

                      (iii) the sale of all or substantially all the assets of
the Company, or a merger, consolidation, or similar transaction of the Company
in which the Company is not the

                                      -4-
<PAGE>

surviving entity or in which the Company's stockholders immediately prior to
such transaction hold less than 50% of the voting securities of the surviving
entity.

                  A "change in control" shall not include either of the
following events:

                      (i)   a transaction, the sole purpose of which is to
change the state of the Company's incorporation; or

                      (ii)  a transaction, the result of which is to sell all or
substantially all of the assets of the Company to another entity (the "surviving
entity"); provided that the surviving entity is owned directly or indirectly by
the Company's stockholders immediately following such transaction in
substantially the same proportions as their ownership of the Company's voting
capital stock immediately preceding such transaction.

                  (e) In addition, if the Omnipoint Technology Division ("OT")
is sold and following such sale the Employee remains an employee of OT at the
request of the Company, then no Shares shall remain subject to the Purchase
Option, and any outstanding amounts under the Note will be forgiven.

                  (f) At the fifth anniversary, upon the Employee's receipt of
the Special Bonus, as defined in the Employment Agreement, if the Employee is
unable to sell Shares to pay federal and state income taxes on compensation
arising due to the Special Bonuses due to limitations imposed under the
Securities Act of 1933, as amended (the "Securities Act"), and the Securities
Exchange Act of 1934, as amended, if any, the Company shall make reasonable
efforts to secure a loan for the Employee to pay such taxes.

                  5.  Restrictions on Transfer.
                      ------------------------

                  (a) The Employee shall not sell, assign, pledge or otherwise
transfer (collectively, "transfer") the Shares or any right or interest therein,
whether voluntarily or by operation of law, or by gift or otherwise, unless the
Purchase Option has expired with respect to the Shares to be so transferred.

                  (b) The Company shall not be required:

                      (i)   to transfer on its books any of the shares which
shall have been sold or transferred in violation of any of the provisions set
forth in this Agreement; or

                      (ii)  to treat as owner of such Shares or to pay dividends
to any transferee to whom any such Shares shall have been so sold or
transferred.

                  (c) All certificates representing Shares shall have affixed
thereto legends in substantially the following form, in addition to any other
legend that may be required under federal or state securities laws:

                                      -5-
<PAGE>

                  "The shares represented by this certificate have not been
         registered under the Securities Act of 1933, as amended, and may not be
         sold, transferred or otherwise disposed of in the absence of an
         effective registration statement under such Act or an opinion of
         counsel satisfactory to the corporation to the effect that such
         registration is not required."

                  The Company shall remove the foregoing legend following the
satisfaction of the registration requirements under the Securities Act or until
such time as the Employee may sell the Shares pursuant to Rule 144(k) of the
Securities Act without restriction.

                  In addition, 40,000 of the shares shall have affixed thereto
legends in substantially the following form:

                  "The shares of stock represented by this certificate are
         subject to restrictions on transfer set forth in a certain Stock
         Restriction Agreement between the corporation and the registered owner
         of this certificate (or his or her predecessor in interest), and such
         Agreement is available for inspection without charge at the office of
         the Treasurer of the corporation."

                  The Company shall remove this legend upon the expiration of
the Purchase Option with respect to the Shares.

                  6.  Investment Representations. The Employee represents,
                      --------------------------
warrants and covenants as follows:

                  (a) The Employee is purchasing the Shares for his own account
for investment only, and not with a view to, or for sale in connection with, any
distribution of the Shares in violation of the Securities Act of 1933 (the
"Securities Act"), or any rule or regulation under the Securities Act.

                  (b) He has had such opportunity as he has deemed adequate to
obtain from representatives of the Company such information as is necessary to
permit him to evaluate the merits and risks of his investment in the Company.

                  (c) He has sufficient experience in business, financial and
investment matters to be able to evaluate the risks involved in the purchase of
the Shares and to make an informed investment decision with respect to such
purchase.

                  (d) He can afford a complete loss of the value of the Shares
and is able to bear the economic risk of holding such Shares for an indefinite
period.

                  (e) He understands that:

                                      -6-
<PAGE>

                  (i)   the Shares have not been registered under the Securities
Act and are "restricted securities" within the meaning of Rule 144 under the
Securities Act;

                  (ii)  the Shares cannot be sold, transferred or otherwise
disposed of unless they are subsequently registered under the Securities Act or
an exemption from registration is then available;

                  (iii) in any event, the exemption from registration under Rule
144 will not be available for at least one year (effective April 29, 1997) and
even then will not be available unless a public market then exists for the
Common Stock, adequate information concerning the Company is then available to
the public, and other terms and conditions of Rule 144 are complied with; and

                  (iv)  there is now no registration statement on file with the
Securities and Exchange Commission with respect to the Shares and although the
Company has no obligation or current intention to register the Shares under the
Securities Act, the Company may choose to register the Shares in the future.

                  7.    Adjustments for Stock Splits, Stock Dividends, etc.
                        ---------------------------------------------------

                  (a)   If from time to time during the term of this Agreement
there is any stock split-up, stock dividend, stock distribution or other
reclassification of the Common Stock of the Company, any and all new,
substituted or additional securities to which the Employee is entitled by reason
of his ownership of the Shares shall be immediately subject to the Purchase
Option granted to the Company pursuant to Section 2 hereof, the restrictions on
transfer and other provisions of this Agreement in the same manner and to the
same extent as the Shares.

                  (b)   If the Shares are converted into or exchanged for, or
stockholders of the Company receive by reason of any distribution in total or
partial liquidation, securities of another corporation, or other property
(including cash), pursuant to any merger of the Company or acquisition of its
assets, then the rights of the Company under this Agreement shall inure to the
benefit of the Company's successor and this Agreement shall apply to the
securities or other property received upon such conversion, exchange or
distribution in the same manner and to the same extent as the Shares.

                  8.    Severability. The invalidity or unenforceability of any
                        ------------
provision of this Agreement shall not affect the validity or enforceability of
any other provision of this Agreement, and each other provision of this
Agreement shall be severable and enforceable to the extent permitted by law.
