                                    TERMS OF
                             CONTINGENT VALUE RIGHTS

        1. This Certificate of Contingent Value Rights ("CVRs") entitles the
holder hereof to ____ CVRs.

        2. Not later than the forty-fifth calendar day following the end of each
Six Month Period, SmarTalk shall mail to each holder of a CVR with respect to
each CVR the CVR Payable (subject to withholding as provided herein). The
Payment shall be made in shares of SmarTalk Common Stock, without interest
thereon; provided, that, notwithstanding the price at which SmarTalk Common
Stock may then be trading, for purposes hereof SmarTalk Common Stock shall be
deemed to have a value of $14.00 per share; and provided, further, in lieu of
any resulting fractional shares, the number of shares shall be rounded upward to
the nearest whole number.

        3. There shall be withheld from each January/June Payment an amount
equal to 25% of such January/June Payment. In the event that the January/June
Payment actually paid is less than the January/June Payment that (but for the
25% withholding) would have been payable based on Actual Results, such
difference shall be paid to the holder of a CVR at the time of the next
July/December Payment. In the event that the January/June Payment actually paid
is more than the January/June Payment would have been payable if based on Actual
Results, such difference shall be deducted from the next Payment, if any, to
which such holder is entitled.

        4. The rights represented by a CVR are non-transferable, except as
required by law. Holders of CVRs shall have no voting or equity rights by virtue
thereof.

        5. In addition to any other amounts which may be withheld pursuant to
the terms hereof, SmarTalk may make appropriate withholding for taxes or similar
items to the extent required by law.

        6. SmarTalk will make available to the CVR Designee financial and other
information with respect to the computations hereunder. In the event that there
shall be a dispute with respect to such computations that cannot be resolved
despite good faith efforts, the dispute shall be submitted by either party to
J.A.M.S./Endispute (the "Arbitrator") for final and binding arbitration in New
York pursuant to the Arbitrator's arbitration rules, with the costs thereof
borne equally by the holders of the CVRs and SmarTalk unless it is determined by
the Arbitrator that either party did not have a substantial basis for submitting
the matter to arbitration, in which event such party shall pay all costs and
expenses associated with the arbitration.

        7. In the event that, after the date of issuance hereof, there shall
have been a Change of Control, payments of all remaining CVR Payables for Six
Month Periods not


   2



then completed shall be deemed to have been accelerated and, in settlement
thereof and in lieu of any future Payments (other than the Payment, if any,
which may then be payable with respect to the most recently completed Six Month
Period), there shall be paid to the holder of a CVR an amount equal to the
Settlement Amount.

        8. As used herein, the following terms shall have the definitions
ascribed to them:
