              FIRST AMENDMENT TO QWEST COMMUNICATIONS CORPORATION
                               SERVICES AGREEMENT

This First Amendment (this "First Amendment") to the Qwest Communications
Corporation Services Agreement is by and between Qwest Communications
Corporation ("Qwest") and General Magic ("Customer"). This First Amendment will
be effective upon Customer's signature date below (the "First Amendment
Effective Date").

WHEREAS, Qwest and Customer entered into a Qwest Communications Corporation
Services Agreement signed by Customer on April 30, 1998 (the "Agreement"), and

WHEREAS, during Qwest's provision of Services pursuant to this Agreement the
Customer experienced Service outages, and

WHEREAS, to provide a remedy for such Service outages, Qwest agrees to adjust
Customer's Usage Minimum, and

WHEREAS, as consideration for such adjustment, Customer agrees not to commence
litigation against Qwest for such Service outages experienced before the
Effective Date of this First Amendment;

WHEREAS, the Parties do not intend to alter Customer's termination rights
pursuant to the Agreement regarding Qwest's provision of Services;

WHEREAS, the parties desire to amend the Agreement.

NOW, THEREFORE, in consideration thereof, the parties agree as follows:

1.  The second and third unnumbered paragraphs on Page 1 of the Agreement are
    deleted and replaced with the following:

    Qwest will provide to Customer international, interstate and intrastate
    telecommunications service(s) (the "Services") pursuant to this Agreement
    and the Qwest FCC Tariffs No. 2 and No. 3 and any applicable intrastate
    tariff of Qwest and/or its affiliates (individually, a "Tariff" and
    collectively, the "Tariffs"), to the extent permitted by law. Capitalized
    terms not otherwise defined herein shall have the meaning given them in the
    applicable Tariff. This Agreement incorporates by reference the terms of
    the Tariffs, which Qwest may modify from time to time in accordance with
    law. Federal law prohibits Qwest from providing interLATA long distance
    services in Arizona, Colorado, Idaho, Iowa, Minnesota, Montana, Nebraska,
    New Mexico, North Dakota, Oregon, South Dakota, Utah, Washington, and
    Wyoming (i.e., voice and data services that originate in such states,
    private line with one end point in those states, or toll free service that
    terminates in such states) until Qwest has obtained authorization to
    provide such services in those states. Customer represents that it has
    received from a competitor of Qwest an offer comparable to the offer set
    forth in this Agreement.

    If prior to the expiration of the Initial Term or Renewal Term of this
    Agreement, Qwest is required to cancel any Tariff, or portion thereof, on
    file with the Federal Communications Commission ("FCC") or is prohibited
    from filing a specific tariff option reflecting the terms of this
    Agreement, as a result of a government or judicial action, then effective
    on such cancellation or prohibition ("Cancellation Date"), as applicable,
    and for the remainder of the Initial Term or Renewal Term:

    (a) The specific provisions contained in this Agreement that expressly apply
        in lieu of, or that apply in addition to, provisions contained in the
        Tariffs and/or in Qwest's Rate and Service Schedules ("Rate Schedules")
        shall be controlling; and

    (b) Provisions contained in the Rate Schedules shall be subordinate to the
        specific provisions in this Agreement as described in (a).

<PAGE>   2

    (c) Notwithstanding the above, for services for which a Tariff is required
        to be filed or is permitted after the Cancellation Date to be filed, the
        Qwest Tariff provisions that remain in effect, as Qwest may amend from
        time to time in accordance with law, shall be controlling over the terms
        contained in this Agreement or the Rate Schedule.

    Any references to a Tariff under this Agreement pertaining to the services
    contained in the Rate Schedules shall be deemed to refer to the Rate
    Schedules. Qwest may amend the Rate Schedules from time to time. The Rate
    Schedules shall incorporate or be deemed to incorporate the applicable
    provisions of the Tariff in effect immediately prior to the cancellation of
    the Tariff provisions.

2.  Section 3.1 of Attachment A is amended by revising the Revenue Level
    Commitment for Year 3 by deleting the figure "$8,000,000" and replacing it
    with One Hundred Twenty Five Thousand Dollars ("$125,000") so the table
    reads as follows:

<TABLE>
<S>             <C>
    Year 1      $1,000,000
    Year 2      $4,000,000
    Year 3      $  125,000
</TABLE>

3.  Except as expressly modified by this First Amendment, the Agreement shall
    continue in full force and effect in accordance with its terms and
    constitutes the legal and binding obligations of Customer and Qwest. In the
    event the terms of this First Amendment conflict with the terms of the
    Agreement, the terms of this First Amendment shall control.

4.  This First Amendment and the Agreement constitute the complete agreement of
    the parties concerning the subject matter hereof, and supersedes any prior
    written or verbal statements, representations, and agreements concerning
    the subject matter hereof.

This First Amendment is of no force or effect unless Customer executes and
delivers it to Qwest Communications Corporation on or before September 29, 2000.

<PAGE>   4

                      (vii) to reduce the exercise price of any Option to the

granted;

                      (viii) to institute an Option Exchange Program;

                      (ix) to construe and interpret the terms of the Plan and
awards granted pursuant to the Plan;

                      (x) to prescribe, amend and rescind rules and regulations

established for the purpose of qualifying for preferred tax treatment under
foreign tax laws;

                      (xi) to modify or amend each Option (subject to Section

obligations by electing to have the Company withhold from the Shares to be
issued upon exercise of an Option that number of Shares having a Fair Market
Value equal to the amount required to be withheld. The Fair Market Value of the
Shares to be withheld shall be determined on the date that the amount of tax to
be withheld is to be determined. All elections by an Optionee to have Shares
withheld for this purpose shall be made in such form and under such conditions
as the Administrator may deem necessary or advisable; and

                      (xv) to make all other determinations deemed necessary or

decisions, determinations and interpretations shall be final and binding on all
Optionees and any other holders of Options.

provided, however, that notwithstanding anything to the contrary contained in
the Plan, Options may not be granted to Officers and Directors.

        6.     Limitation. Neither the Plan nor any Option shall confer upon an
Optionee any right with respect to continuing the Optionee's relationship as a
Service Provider with the Company, nor shall they interfere in any way with the
Optionee's right or the Company's right to terminate such relationship at any
time, with or without cause.

        7.     Term of Plan. The Plan shall become effective upon its adoption
by the Board. It shall continue in effect for ten (10) years, unless sooner
terminated under Section 14 of the Plan.

                                      -4-
<PAGE>   5

        8.     Term of Option. The term of each Option shall be stated in the
Option Agreement.

        9.     Option Exercise Price and Consideration.

               (a) Exercise Price. The per share exercise price for the Shares
to be issued pursuant to exercise of an Option shall be determined by the
Administrator.

               (b) Waiting Period and Exercise Dates. At the time an Option is
granted, the Administrator shall fix the period within which the Option may be
exercised and shall determine any conditions which must be satisfied before the
Option may be exercised.

               (c) Form of Consideration. The Administrator shall determine the
acceptable form of consideration for exercising an Option, including the method
of payment. Such consideration may consist entirely of:

                      (i) cash;

                      (ii) check;

                      (iii) promissory note;

                      (iv) other Shares, provided Shares acquired from the
Company, (A) have been owned by the Optionee for more than six (6) months on the
date of surrender, and (B) have a Fair Market Value on the date of surrender
equal to the aggregate exercise price of the Shares as to which said Option
shall be exercised;

                      (v) consideration received by the Company under a cashless
exercise program implemented by the Company in connection with the Plan;

                      (vi) a reduction in the amount of any Company liability to
the Optionee, including any liability attributable to the Optionee's
participation in any Company-sponsored deferred compensation program or
arrangement;

                      (vii) such other consideration and method of payment for
the issuance of Shares to the extent permitted by Applicable Laws; or

                      (viii) any combination of the foregoing methods of
payment.

        10.    Exercise of Option.

               (a) Procedure for Exercise; Rights as a Shareholder. Any Option
granted hereunder shall be exercisable according to the terms of the Plan and at
such times and under such conditions as determined by the Administrator and set
forth in the Option Agreement. An Option may not be exercised for a fraction of
a Share.

                      An Option shall be deemed exercised when the Company
receives: (i) written or electronic notice of exercise (in accordance with the
Option Agreement) from the person entitled to exercise

                                      -5-
<PAGE>   6

the Option, and (ii) full payment for the Shares with respect to which the
Option is exercised. Full payment may consist of any consideration and method of
payment authorized by the Administrator and permitted by the Option Agreement
and the Plan. Shares issued upon exercise of an Option shall be issued in the
name of the Optionee or, if requested by the Optionee, in the name of the
Optionee and his or her spouse. Until the Shares are issued (as evidenced by the
appropriate entry on the books of the Company or of a duly authorized transfer
agent of the Company), no right to vote or receive dividends or any other rights
as a shareholder shall exist with respect to the Optioned Stock, notwithstanding
the exercise of the Option. The Company shall issue (or cause to be issued) such
Shares promptly after the Option is exercised. No adjustment will be made for a
dividend or other right for which the record date is prior to the date the
Shares are issued, except as provided in Section 12 of the Plan.

                      Exercising an Option in any manner shall decrease the
number of Shares thereafter available, both for purposes of the Plan and for
sale under the Option, by the number of Shares as to which the Option is
exercised.

               (b) Termination of Relationship as a Service Provider. If an
Optionee ceases to be a Service Provider, other than upon the Optionee's death
or Disability, the Optionee may exercise his or her Option, but only within such
period of time as is specified in the Option Agreement, and only to the extent
that the Option is vested on the date of termination (but in no event later than
the expiration of the term of such Option as set forth in the Option Agreement).
In the absence of a specified time in the Option Agreement, the Option shall
remain exercisable for three (3) months following the Optionee's termination.
If, on the date of termination, the Optionee is not vested as to his or her
entire Option, the Shares covered by the unvested portion of the Option shall
revert to the Plan. If, after termination, the Optionee does not exercise his or
her Option within the time specified by the Administrator, the Option shall
terminate, and the Shares covered by such Option shall revert to the Plan.

               (c) Disability of Optionee. If an Optionee ceases to be a Service
Provider as a result of the Optionee's Disability, the Optionee may exercise his
or her Option within such period of time as is specified in the Option
Agreement, to the extent the Option is vested on the date of termination (but in
no event later than the expiration of the term of such Option as set forth in
the Option Agreement). In the absence of a specified time in the Option
Agreement, the Option shall remain exercisable for twelve (12) months following
the Optionee's termination. If, on the date of termination, the Optionee is not
vested as to his or her entire Option, the Shares covered by the unvested
portion of the Option shall revert to the Plan. If, after termination, the
Optionee does not exercise his or her Option within the time specified herein,
the Option shall terminate, and the Shares covered by such Option shall revert
to the Plan.

               (d) Death of Optionee. If an Optionee dies while a Service
Provider, the Option may be exercised within such period of time as is specified
in the Option Agreement (but in no event later than the expiration of the term
of such Option as set forth in the Notice of Grant), by the Optionee's estate or
by a person who acquires the right to exercise the Option by bequest or
inheritance, but only to the extent that the Option is vested on the date of
death. In the absence of a specified time in the Option Agreement, the Option
shall remain exercisable for twelve (12) months following the Optionee's
termination. If, at the time of death, the Optionee is not vested as to his or
her entire Option, the Shares covered by the unvested portion of the Option
shall immediately revert to the Plan. The Option may be exercised by the
executor or administrator of the Optionee's estate or, if none, by the person(s)
entitled to exercise the Option under the

                                      -6-
<PAGE>   7

Optionee's will or the laws of descent or distribution. If the Option is not so
exercised within the time specified herein, the Option shall terminate, and the
Shares covered by such Option shall revert to the Plan.

               (e) Buyout Provisions. The Administrator may at any time offer to
buy out for a payment in cash or Shares, an Option previously granted based on
such terms and conditions as the Administrator shall establish and communicate
to the Optionee at the time that such offer is made.

        11.    Non-Transferability of Options. Unless determined otherwise by
the Administrator, an Option may not be sold, pledged, assigned, hypothecated,
transferred, or disposed of in any manner other than by will or by the laws of
descent or distribution and may be exercised, during the lifetime of the
Optionee, only by the Optionee. If the Administrator makes an Option
transferable, such Option shall contain such additional terms and conditions as
the Administrator deems appropriate.

        12.    Adjustments Upon Changes in Capitalization, Dissolution, Merger
or Asset Sale.

               (a) Changes in Capitalization. Subject to any required action by
the shareholders of the Company, the number of shares of Common Stock covered by
each outstanding Option, and the number of shares of Common Stock which have
been authorized for issuance under the Plan but as to which no Options have yet
been granted or which have been returned to the Plan upon cancellation or
expiration of an Option, as well as the price per share of Common Stock covered
by each such outstanding Option, shall be proportionately adjusted for any
increase or decrease in the number of issued shares of Common Stock resulting
from a stock split, reverse stock split, stock dividend, combination or
reclassification of the Common Stock, or any other increase or decrease in the
number of issued shares of Common Stock effected without receipt of
consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration." Such adjustment shall be made by the Board,
whose determination in that respect shall be final, binding and conclusive.
Except as expressly provided herein, no issuance by the Company of shares of
stock of any class, or securities convertible into shares of stock of any class,
shall affect, and no adjustment by reason thereof shall be made with respect to,
the number or price of shares of Common Stock subject to an Option.

               (b) Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, the Administrator shall notify each
Optionee as soon as practicable prior to the effective date of such proposed
transaction. The Administrator in its discretion may provide for an Optionee to
have the right to exercise his or her Option until ten (10) days prior to such
transaction as to all of the Optioned Stock covered thereby, including Shares as
to which the Option would not otherwise be exercisable. In addition, the
Administrator may provide that any Company repurchase option applicable to any
Shares purchased upon exercise of an Option shall lapse as to all such Shares,
provided the proposed dissolution or liquidation takes place at the time and in
the manner contemplated. To the extent it has not been previously exercised, an
Option will terminate immediately prior to the consummation of such proposed
action.

               (c) Merger or Asset Sale. In the event of a merger of the Company
with or into another corporation, or the sale of substantially all of the assets
of the Company, each outstanding Option shall be assumed or an equivalent option
or right substituted by the successor corporation or a Parent or Subsidiary of
the successor corporation. In the event that the successor corporation refuses
to assume or substitute for the Option, the Optionee shall fully vest in and
have the right to exercise the Option as to all of the Optioned Stock, including
Shares as to which it would not otherwise be vested or exercisable. If an Option
becomes fully vested and exercisable in lieu of assumption or substitution in
the event of a merger or sale of assets,

                                      -7-
<PAGE>   8

the Administrator shall notify the Optionee in writing or electronically that
the Option shall be fully vested and exercisable for a period of fifteen (15)
days from the date of such notice, and the Option shall terminate upon the
expiration of such period. For the purposes of this paragraph, the Option shall
be considered assumed if, following the merger or sale of assets, the option or
right confers the right to purchase or receive, for each Share of Optioned
Stock, immediately prior to the merger or sale of assets, the consideration
(whether stock, cash, or other securities or property) received in the merger or
sale of assets by holders of Common Stock for each Share held on the effective
date of the transaction (and if holders were offered a choice of consideration,
the type of consideration chosen by the holders of a majority of the outstanding
Shares); provided, however, that if such consideration received in the merger or
sale of assets is not solely common stock of the successor corporation or its
Parent, the Administrator may, with the consent of the successor corporation,
provide for the consideration to be received upon the exercise of the Option,
for each Share of Optioned Stock to be solely common stock of the successor
corporation or its Parent equal in fair market value to the per share
consideration received by holders of Common Stock in the merger or sale of
assets.

        13.    Date of Grant. The date of grant of an Option shall be, for all
purposes, the date on which the Administrator makes the determination granting
such Option, or such other later date as is determined by the Administrator.
Notice of the determination shall be provided to each Optionee within a
reasonable time after the date of such grant.

        14.    Amendment and Termination of the Plan.

               (a) Amendment and Termination. The Board may at any time amend,
alter, suspend or terminate the Plan.

               (b) Effect of Amendment or Termination. No amendment, alteration,
suspension or termination of the Plan shall impair the rights of any Optionee,
unless mutually agreed otherwise between the Optionee and the Administrator,
which agreement must be in writing and signed by the Optionee and the Company.
Termination of the Plan shall not affect the Administrator's ability to exercise
the powers granted to it hereunder with respect to options granted under the
Plan prior to the date of such termination.

        15.    Conditions Upon Issuance of Shares.

               (a) Legal Compliance. Shares shall not be issued pursuant to the
exercise of an Option unless the exercise of such Option and the issuance and
delivery of such Shares shall comply with Applicable Laws and shall be further
subject to the approval of counsel for the Company with respect to such
compliance.

               (b) Investment Representations. As a condition to the exercise of
an Option the Company may require the person exercising such Option to represent
and warrant at the time of any such exercise that the Shares are being purchased
only for investment and without any present intention to sell or distribute such
Shares if, in the opinion of counsel for the Company, such a representation is
required.

        16.    Inability to Obtain Authority. The inability of the Company to
obtain authority from any regulatory body having jurisdiction, which authority
is deemed by the Company's counsel to be necessary to the lawful issuance and
sale of any Shares hereunder, shall relieve the Company of any liability in
respect of the failure to issue or sell such Shares as to which such requisite
authority shall not have been obtained.

                                      -8-

        17.    Reservation of Shares. The Company, during the term of this Plan,
will at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

        II.    AGREEMENT

               1. Grant of Option. The Plan Administrator of the Company hereby
grants to the Optionee named in the Notice of Grant attached as Part I of this
Agreement (the "Optionee") an option (the "Option") to purchase the number of
Shares, as set forth in the Notice of Grant, at the exercise price per share set
forth in the Notice of Grant (the "Exercise Price"), subject to the terms and
conditions of the Plan, which is incorporated herein by reference. Subject to
Section 14(b) of the Plan, in the event of a conflict between the terms and
conditions of the Plan and the terms and conditions of this Option Agreement,
the terms and conditions of the Plan shall prevail.

               2.     Exercise of Option.

                          (a) Right to Exercise. This Option is exercisable
during its term in accordance with the Vesting Schedule set out in the Notice of
Grant and the applicable provisions of the Plan and this Option Agreement.

                          (b)Method of Exercise. This Option is exercisable by
delivery of an exercise notice, in the form attached as Exhibit A (the "Exercise
Notice"), which shall state the election to exercise the Option, the number of
Shares in respect of which the Option is being exercised (the "Exercised
Shares"), and such other representations and agreements as may be required by
the Company pursuant to the provisions of the Plan. The Exercise Notice shall be
completed by the Optionee and delivered to the Company. The Exercise Notice
shall be accompanied by payment of the aggregate Exercise Price as to all
Exercised Shares. This Option shall be deemed to be exercised upon receipt by
the Company of such fully executed Exercise Notice accompanied by such aggregate
Exercise Price.

               No Shares shall be issued pursuant to the exercise of this Option
unless such issuance and exercise complies with Applicable Laws. Assuming such
compliance, for income tax purposes the Exercised Shares shall be considered
transferred to the Optionee on the date the Option is exercised with respect to
such Exercised Shares.

               3.     Method of Payment. Payment of the aggregate Exercise Price
shall be by any of the following, or a combination thereof, at the election of
the Optionee:

                          (a) cash;

                          (b) check;

                          (c) consideration received by the Company under a
cashless exercise program implemented by the Company in connection with the
Plan; or

                          (d) surrender of other Shares, provided Shares
acquired from the Company, (i) have been owned by the Optionee for more than six
(6) months on the date of surrender, AND (ii) have a Fair Market Value on the
date of surrender equal to the aggregate Exercise Price of the Exercised Shares.

               4.     Non-Transferability of Option. This Option may not be
transferred in any manner otherwise than by will or by the laws of descent or
distribution and may be exercised during the lifetime of

                                      -2-
<PAGE>   12

Optionee only by the Optionee. The terms of the Plan and this Option Agreement
shall be binding upon the executors, administrators, heirs, successors and
assigns of the Optionee.

               5.     Term of Option.  This Option may be exercised only within
the term set out in the Notice of Grant, and may be exercised during such term
only in accordance with the Plan and the terms of this Option Agreement.

               6.     Withholding Taxes. Optionee agrees to make appropriate
arrangements with the Company (or the Parent or Subsidiary employing or
retaining Optionee) for the satisfaction of all Federal, state, and local income
and employment tax withholding requirements applicable to the Option exercise.
Optionee acknowledges and agrees that the Company may refuse to honor the
exercise and refuse to deliver Shares if such withholding amounts are not
delivered.

               7.     Entire Agreement; Governing Law. The Plan is incorporated
herein by reference. The Plan and this Option Agreement constitute the entire
agreement of the parties with respect to the subject matter hereof and supersede
in their entirety all prior undertakings and agreements of the Company and
Optionee with respect to the subject matter hereof, and may not be modified
adversely to the Optionee's interest except by means of a writing signed by the
Company and Optionee. This agreement is governed by the internal substantive
laws, but not the choice of law rules, of California.

               8.     NO GUARANTEE OF CONTINUED SERVICE. OPTIONEE ACKNOWLEDGES
AND AGREES THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS
EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (AND
NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED AN OPTION OR PURCHASING SHARES
HEREUNDER). OPTIONEE FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE
TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO
NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A
SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL
NOT INTERFERE WITH OPTIONEE'S RIGHT OR THE COMPANY'S RIGHT TO TERMINATE
OPTIONEE'S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT
CAUSE.
