ITEM 2. ACQUISITION OF ASSETS.

      On December 31, 1997, SmarTalk TeleServices, Inc., a California
corporation ("SmarTalk"), consummated the initial closing of the acquisition of
the issued and outstanding common stock, $0.01 par value per share (the
"Shares"), of American Express Telecom, Inc., a Delaware corporation (the
"Company"), from American Express Travel Related Services Company, a New York
corporation and sole stockholder of the Company (the "Stockholder"), pursuant to
a Stock Purchase Agreement, dated as of December 22, 1997 (the "Agreement"), by
and among SmarTalk, the Company and the Stockholder.

      In consideration for the Shares, SmarTalk paid to the Stockholder
thirty-four million dollars ($34,000,000) in cash, which was provided from
SmarTalk's working capital, a portion of which is to be held in escrow pending
regulatory approval. At the initial closing, SmarTalk acquired eighty percent
(80%) of the Shares. The Agreement is filed as Exhibit 2.1 hereto.

      The consideration paid for the Shares was determined based upon
arms-length negotiations between SmarTalk and the Stockholder. To the best of
SmarTalk's knowledge, prior to the execution of the Agreement, there was no
material relationship between the Stockholder and SmarTalk or any affiliates of
SmarTalk, any director or officer of SmarTalk or any associate of any such
director or officer.

and deliver any and all other documents and instruments and take any and all
such


                                       2

other action as may be reasonably necessary or desirable to effectuate the
transactions set forth herein or contemplated hereby, and the officers and

effectuate such transactions.

            1.6.  Further Acts and Assurances. The Stockholder shall, at any

will cause to be done, executed, acknowledged and delivered, such further acts,
deeds, assignments, transfers, conveyances, powers of attorney and assurances

                                    ARTICLE 2

                    CONSIDERATION FOR PURCHASE OF THE SHARES

            2.1.  Payment for the Shares. SmarTalk agrees to pay for the Shares
the Purchase Price as defined in Section 2.2 herein by delivery of cash in the
form of a wire transfer or check.

            2.2.  Purchase Price. The aggregate purchase price for the Shares
shall be $34 million (the "Purchase Price").

            2.3.  Settlement of Closing Date Liabilities for Sold But Unused
Calling Time. (a) Within 30 days following the Initial Closing, the Stockholder
shall cause to be prepared and delivered to SmarTalk a statement prepared by
Ernst & Young setting forth (i) the total number of minutes of unused calling
time outstanding as of the Initial Closing on prepaid telephone calling cards
sold by the Company through the date of the Initial Closing, (ii) the
Stockholder's good faith estimate of the amount of such unused calling time that
will actually be used prior to the expiration dates of the sold cards based on
the past 12 months usage experience, which shall not be less than 80% of the
maximum potential liability (the "Estimated Usage"), together with appropriate
documentation of historical usage and any other methodology used by Ernst &
Young to make such estimate and (iii) the aggregate estimated liability of the
Company if such Estimated Usage were the actual number of minutes used with
respect to such sold cards prior to their expiration calculated by multiplying
(x) the total number of minutes reflected in the Estimated Usage times (y) $0.20
(the "Proposed Unused Call Settlement Amount").


                                       3
<PAGE>   9
            (b)   Within 30 days of receipt of the Proposed Unused Call
Settlement Amount statement, SmarTalk shall notify the Stockholder if it agrees
with the Proposed Unused Call Settlement Amount, or if it desires to dispute the
Proposed Unused Call Settlement Amount, in which case such notice will include a
statement setting forth SmarTalk's alternative proposal (the "Alternative Unused
Call Settlement Amount") and the estimated usage and other methodology used by
SmarTalk to calculate the Alternative Unused Call Settlement Amount. If SmarTalk
fails to deliver a notice of dispute within the 30-day period following delivery
to it of the Stockholder's statement containing the Proposed Unused Call
Settlement Amount, then the Proposed Unused Call Settlement Amount shall be
deemed to be the "Final Unused Call Settlement Amount" for purposes of the final
sentence of this Section 2.3. If SmarTalk delivers a notice disputing the
Proposed Unused Call Settlement Amount and containing an Alternative Unused Call
Settlement Amount within such 30-day period, SmarTalk and the Stockholder shall
endeavor in good faith to resolve the dispute within 30 days after the
Stockholder's receipt of SmarTalk's notice containing the Alternative Unused
Call Settlement Amount. If the Stockholder and SmarTalk are able to resolve the
dispute within such 30-day period, then the amount to which they agree shall be
deemed to be the "Final Unused Call Settlement Amount" for purposes of the final
sentence of this Section 2.3. If the Stockholder and SmarTalk are unable to
resolve the dispute within such 30-day period, the Stockholder and SmarTalk
shall thereupon select within five days an internationally known independent
accounting firm other than the firms engaged by the Stockholder and SmarTalk
(the "Independent Accounting Firm") to resolve the dispute within 60 days of
selection and the determination of the Independent Accounting Firm shall be
conclusive and binding on the Stockholder and SmarTalk and the amount of the
Unused Call Settlement Amount so determined by the Independent Accounting Firm,
in the event it is required to make such determination, shall be deemed to be
the "Final Unused Call Settlement Amount" for purposes of the final sentence of
this Section 2.3. The Final Unused Call Settlement Amount, whether determined by
the Stockholder and agreed to or not disputed by SmarTalk or whether determined
by mutual agreement of the Stockholder and SmarTalk or whether determined by the
Independent Accounting Firm, shall be promptly paid after its date of
determination by the Stockholder to SmarTalk by wire transfer in immediately
available funds.

            2.4.  Payment Schedule.At the Initial Closing, SmarTalk shall pay
the Stockholder the amount of $26 million, pursuant to Section 2.1 above, in
exchange for delivery of 80% of the Shares. At the Initial Closing, SmarTalk
shall deposit, pursuant to the terms of an escrow agreement (the "Escrow
Agreement"), the amount of $8 million, to be held and disbursed in accordance
with the Escrow Agreement. Similarly, the Stockholder will hold as escrow agent
the balance of the Shares to be conveyed in accordance with the Escrow
Agreement.

                         REPRESENTATIONS AND WARRANTIES
                         OF THE STOCKHOLDER AND COMPANY

            The Stockholder and the Company hereby jointly and severally
represent and warrant to SmarTalk as follows:

            3.1.  Corporate Organization and Disclosure. (a) The Company is a
corporation duly organized, validly existing and in good standing under the laws
of the State of Delaware with all requisite power and authority to own, lease
and operate its properties and to carry on its business as now being conducted.
The Company is qualified to do business and is in good standing in each
jurisdiction (domestic, foreign or otherwise) in which the property owned,
leased or operated by it or the nature of the business conducted by it makes
such qualification necessary, except where the failure to so qualify or be in
good standing would not have a Material Adverse Effect (as defined in Section
3.4(b)). Schedule 3.1(a) contains a list of all jurisdictions where the Company
is qualified to do business. The Company has not received any written notice or
assertion from the Secretary of State or comparable official of any jurisdiction
to the effect that the Company is required to be qualified or otherwise
authorized to do business therein, in which the Company has not qualified or
obtained such authorization.

            (b)   Complete copies of the charter and all amendments thereto to
the date hereof and the Bylaws (or equivalent organizational documents) as
presently in effect of the Company have been furnished to SmarTalk. The Company
is not in default in the performance, observation or fulfillment of its charter
or Bylaws (or equivalent organizational documents).

            (c)   True and complete copies of the minute books of the Company,
which record all meetings of the Board of Directors of the Company and
committees thereof and all meetings of its stockholders and all actions by
written consent without a meeting by such Boards of Directors and committees
thereof and its stockholders since the date of incorporation, have been
furnished to SmarTalk. The stock certificate books and records of the Company
accurately reflect on the date hereof the ownership of the Shares by the persons
and in the amounts set forth therein.

            3.2.  Capitalization. The authorized capital stock of the Company
consists solely of 1,000 Common Shares, of which 1,000 are issued and
outstanding, all of which possess identical voting rights and are owned
beneficially and of record by the Stockholder, free and clear of all claims,
liens and encumbrances of any kind. Except as set forth in the preceding
sentence, there are no other shares of capital stock of the Company which are
issued or outstanding. The Stockholder now has, and on the date of each Closing
will have, full power and authority to transfer the Shares to SmarTalk
hereunder. All of the Shares have been validly issued and are fully paid,
non-assessable and are not subject to any


                                       5
<PAGE>   11
preemptive rights. The issuance and sale of all of the Shares have been in full
compliance with all applicable federal and state securities laws. There are no
subscriptions, options, warrants, calls, rights, contracts, commitments,
understandings, restrictions or arrangements relating to the issuance, sale,
transfer or voting of any of the Shares or any other equity security of the
Company, including any rights of conversion or exchange under any outstanding
securities or other instruments. There are no voting rights or other agreements
or understandings with respect to the Shares. The Stockholder has good and valid
title, beneficially and of record, to the Shares in the amount set forth herein,
free and clear of all claims, liens, suits, proceedings, calls, proxies,
charges, options, security interests and encumbrance of any kind; and it now
has, and on the date of each Closing will have, full power and authority to
transfer the Shares to SmarTalk hereunder.

            3.3.  Subsidiaries, Affiliates, Affiliated Companies and Joint
Ventures. The Company does not own any capital stock or other equity securities
of any corporation, has no direct or indirect equity or ownership interest in,
by way of stock ownership or otherwise, any corporation, partnership, joint
venture, association or business enterprise and is not contemplating acquiring
any such interest.

            3.4.  Authority. (a) The execution, delivery and performance of this
Agreement and the consummation of the transactions contemplated hereby by the
Company have been duly authorized by all requisite corporate action, and no
other acts or proceedings on the part of the Company or the Stockholder are
necessary to authorize this Agreement or the transactions contemplated hereby.
The Stockholder has the absolute and unrestricted right, power, authority and
capacity to execute and deliver this Agreement and, as of each Closing,
consummate the transactions contemplated hereby. This Agreement has been duly
and validly executed and delivered by the Company and the Stockholder and
(assuming due authorization, execution and delivery by SmarTalk) is the legal,
valid and binding obligation of the Company and the Stockholder enforceable
against the Company and the Stockholder in accordance with its terms (except (i)
as may be limited by bankruptcy, insolvency, fraudulent transfer,
reorganization, moratorium and similar laws of general applicability relating to
or affecting creditors' rights generally, (ii) that the remedy of specific
performance and injunctive and other forms of equitable relief may be subject to
equitable defenses and to the discretion of the court before which any
proceedings therefor may be brought, and (iii) that the enforceability of any
rights to indemnity or contribution may be limited by federal or state
securities laws or by public policy).

            (b)   Except as set forth in Schedule 3.4, neither the execution and
delivery by the Company and the Stockholder of this Agreement nor the
consummation of the transactions contemplated hereby nor compliance with any of
the provisions hereof will: (i) conflict with or result in a breach of any
provision of the charter or Bylaws (or equivalent organizational documents) of
the Company; (ii)


                                       6
<PAGE>   12
violate, conflict with or result in a breach of any provision of, or constitute
a default (or an event which, with notice or lapse of time or both, would
constitute a default) under, or result in the termination or in a right of
termination or cancellation of, or accelerate the performance required by, or
result in the creation of any encumbrance upon any of the properties of the
Company or result in being declared void, voidable, without further binding
effect or subject to amendment or modification any of the terms, conditions or
provisions of, any note, bond, mortgage, indenture, deed of trust, any license,
franchise, permit, lease, contract, agreement or other instrument or commitment
or obligation to which the Company or any of its properties may be bound or
affected; (iii) violate any order, writ, injunction, decree, judgment, ruling,
law, rule or regulation of any Governmental Authority (as defined below),
applicable to the Company or the Stockholder or any of their respective
properties; or (iv) require any consent, approval or authorization of, or notice
to, or declaration, filing or registration with, any person or entity, except,
in the case of clauses (ii), (iii) and (iv) above, as could not have a Material
Adverse Effect (as hereinafter defined) or as would not be reasonably likely to
have a material adverse effect on the ability of the Company or the Stockholder
to consummate the transactions contemplated hereby. As used in this Agreement, a
"Material Adverse Effect" shall mean, in respect of the Company, any effect or
change that is, or is reasonably likely to be, materially adverse to the
business, operations, assets, financial condition or results of operations of
the Company.

            3.5.  Compliance with Laws. The Company and, to the best knowledge
of the Company, all of its officers, directors, consultants and agents, and
employees of the Stockholder that are assigned to perform services for the
Company (collectively, the "Personnel"), have complied in all material respects
with all applicable statutes, regulations, rules, orders, ordinances, judgments,
decrees, permits, franchises, licenses and other laws of the United States of
America, all state, local and foreign governments and other governmental bodies
and authorities, and courts and agencies of any of the foregoing ("Governmental
Authority") applicable to the Company, except to the extent noncompliance could
not have a Material Adverse Effect. Except as set forth on Schedule 3.5, the
Company has not received any notice or other communication to the effect that,
or otherwise been advised that, it is not in compliance with any of such
statutes, regulations and orders, ordinances, other laws or undertakings, and
neither the Company nor the Stockholder has any knowledge that any presently
existing circumstances are likely to result in violations of any such
regulations which could have a Material Adverse Effect.

            3.6.  Licenses. [Intentionally omitted.]

            3.7.  Financial Statements. Set forth on Schedule 3.7(a) are true,
correct and complete copies of the audited financial statements of the Company

and complete copies of the interim financial statements of the Company
(consisting of a balance sheet, statement of income and statement of cash flow)

Statements have been prepared from and are in accordance with the books and
records of the Company which are complete and accurate, and the Company
Financial Statements fairly present the financial position, results of
operations and changes in financial position of the Company as of the dates and
for the periods indicated, in each case in accordance with United States
generally accepted accounting principles ("GAAP"). The unaudited financial
statements of the Company were prepared on a basis consistent with the Company's
audited financial statements contained in the Company Financial Statements,
subject to normal, recurring year-end adjustments; provided, however, that no
such year-end adjustment shall have a Material Adverse Effect.

            3.8.  Absence of Undisclosed Liabilities. Except (i) as and to the
extent specifically reserved against (which reserves are adequate in amount) in
the Company's audited balance sheet as of December 31, 1996, and in the notes to
such balance sheet for the period then ended, (ii) liabilities which have been
incurred since December 31, 1996, in the ordinary course of business consistent

(iii) liabilities and obligations specifically disclosed on Schedule 3.8, the
Company has no material liabilities or obligations of any nature (whether
accrued, absolute, contingent or otherwise and whether due or to become due).

            3.9.  Absence of Certain Changes. Since December 31, 1996, there has
not been any change in or effect on the business, earnings, assets, liabilities,
financial or other condition or results of operations of the Company that has or
would be reasonably likely to have a Material Adverse Effect and no fact or
condition exists or is reasonably contemplated or threatened which the Company
or the Stockholder believes has a reasonable probability of resulting in any
change in or effect on the business, earnings, assets, liabilities, financial or
other condition or results of operations of the Company that has or could have a
Material Adverse Effect. Without limiting the generality of the foregoing, since
December 31, 1996, and except as set forth on Schedule 3.9, there has not been,
occurred or arisen with respect to the Company any: (a) amendment of its charter
or Bylaws (or equivalent organizational documents); (b) change in the number of

except as set forth on Schedule 3.9(f) hereto; (g) transfer, lease, guarantee,

hearing, investigation or proceeding pending or, to the knowledge of the Company
or the Stockholder, threatened against, relating to or affecting (i) the
Company, (ii) Personnel in reference to actions taken by them in such capacities
or (iii) the transactions contemplated by this Agreement; and (b) neither the
Company nor the Stockholder has knowledge that any presently existing
circumstances are likely to result in any such litigation, proceeding or
investigation, which, with respect to


                                       9
<PAGE>   15
either clause (a) or (b) above, if adversely determined, could have a Material
Adverse Effect or adversely affect the ability of the Company or the Stockholder
to consummate the transactions contemplated hereby. Except as disclosed on

      IRS, or by a comparable form under the laws of other jurisdictions; except
      that a Form 870 or 870-AD or comparable form that reserves (whether by its
      terms or by operation of law) the right of the taxpayer to file a claim
      for a refund shall not constitute a Final Determination; (ii) by a
      decision, judgment, decree or other order of the Tax Court or any other

      that begins on or before the day of the Initial Closing and ends after the

Company on or before the date hereof (taking into account any extensions of
filing dates) have been timely filed. All such Tax Returns (i) were prepared in
the manner required by applicable law, (ii) are true, correct, and complete in
all material respects, and (iii) reflect the liability for Taxes of the Company.
All Taxes shown to be payable on such Tax Returns, and all assessments of Tax

Parent Group's (as hereinafter defined) knowledge, threatened in writing by any
taxing authority.

three years have been made available to SmarTalk prior to the date hereof. Since
the date of the most recent Company Financial Statements, the Company has not
incurred any liability for Taxes other than in respect to which the Stockholder
has agreed to 


                                       11
<PAGE>   17
indemnify SmarTalk that would result in a material decrease in the net worth of
the Company.

all required current estimated Tax payments sufficient to avoid any underpayment
penalties.

            (e)   The Company has timely paid or caused to be paid all Taxes
that are or were due or payable on or prior to the date hereof, whether or not

law, withheld from employee wages and paid over to the proper governmental
authorities all amounts required.

            (g)   None of the Tax Returns of or including the Company has been
examined by the IRS or relevant state, local or foreign taxing authorities.
There are no examinations or other administrative or court proceedings relating
to Taxes in progress or pending nor has the Company received a revenue agent's
report asserting a tax deficiency. To Parent Group's (as hereinafter defined)
knowledge, there are no threatened actions, suits, proceedings, investigations
or claims relating to or asserted for Taxes of the Company.

            (h)   No material claim has ever been made in writing by any taxing
authority with respect to the Company in a jurisdiction where the Company does
not file reports and returns that the Company is or may be subject to taxation
by that jurisdiction. There are no security interests on any of the assets of

and in good standing under the laws of its jurisdiction of incorporation. Each
of SmarTalk and its subsidiaries has full corporate power and authority to own,
lease and operate its properties and to carry on its business as now being
conducted therein, and each such entity is qualified to do business and is in
good standing in each jurisdiction (domestic, foreign or otherwise) in which
property owned, leased or operated by it or the nature of the business conducted
by it makes such qualification necessary (except for jurisdictions in which such

Adverse Effect on the business, earnings, assets, liabilities, financial or
other condition or results of operations of SmarTalk and its subsidiaries taken
as a whole).

            4.2.  Authority. (a) The execution, delivery and performance of this
Agreement and the consummation of the transactions contemplated hereby by
SmarTalk have been duly authorized by all requisite corporate action, and no
other acts or other proceedings on the part of SmarTalk are necessary to

<PAGE>   22
Agreement or the transactions contemplated hereby. This Agreement has been duly

and delivery hereof and thereof by the Company and the Stockholder) constitutes
the legal, valid and binding obligation of SmarTalk, enforceable against
SmarTalk in accordance with its terms, except as enforcement thereof may be
limited by bankruptcy, insolvency, reorganization, moratorium or other similar
laws affecting the enforcement of creditors' rights in general, or by general
principles of equity.

            (b)   Except as set forth in Schedule 4.2(b), neither the execution
and delivery by SmarTalk of this Agreement nor the consummation of the
transactions contemplated hereby nor compliance with any of the provisions
hereof will: (i) conflict with or result in a breach of any provision of the
charter or Bylaws of SmarTalk, or any of its subsidiaries; (ii) violate,
conflict with, or result in a breach of any provision of, or constitute a
default (or an event which, with notice or lapse of time or both, would
constitute a default) under, or result in the termination or in a right of
termination or cancellation of, or accelerate the performance required by, or
result in the creation of any encumbrance upon any of the properties of SmarTalk
or any of its subsidiaries or result in being declared void, voidable, without
further binding effect or subject to amendment or modification any of the terms,
conditions or provisions of, any note, bond, mortgage, indenture, deed of trust,
any license, franchise, permit, lease, contract, agreement or other instrument
or commitment or obligation to which SmarTalk, any of its subsidiaries or any of
their respective properties may be bound or affected; (iii) violate any order,
writ, injunction, decree, judgment, ruling, law, rule or regulation of any
Governmental Authority, applicable to SmarTalk or any of its subsidiaries or any
of their respective properties; or (iv) except for obtaining the consents,
approvals, authorizations and permits of, and making filings or notifications
to, any Governmental Authority pursuant to the applicable requirements, if any,
of state securities laws and the rules and regulations promulgated thereunder,
require any consent, approval or authorization of, or notice to, or declaration,
filing or registration with, any person or entity except as would not be
reasonably likely to have a Material Adverse Effect on the business, earnings,
assets, liabilities, financial or other condition or results of operations of
SmarTalk and its subsidiaries taken as a whole or on the ability of SmarTalk to
consummate the transactions contemplated hereby.

prevent or promptly remedy the same. Upon a material breach of any
representation, warranty or covenant contained herein, the non-breaching party
shall provide the breaching party written notice (a "Notice") pursuant to
Section 12.4 of such breach and the breaching party shall have five business
days after the delivery of such Notice to cure such breach before the
non-breaching party shall have the right to pursue any remedy with respect
thereto.

            5.12. Tax Covenants. (a) At SmarTalk's request, Parent (or with
respect to elections described in (ii), the appropriate direct or indirect
subsidiary 


                                       22
<PAGE>   28
thereof) and SmarTalk shall jointly make: (i) the joint election provided for in
section 338(h)(10) of the Code and Treas. Reg. Section 1.338(h)(10)-1(d) with
respect to the Company; and/or (ii) such other elections, if any, under the laws
of any state, local or foreign jurisdiction analogous to the election provided
for in either section 338(g) or section 338(h)(10) of the Code (the elections
described in (i) and (ii) collectively, the "Section 338 Elections"). Parent,
the Stockholder and SmarTalk shall comply fully with all filing and other
requirements necessary to effectuate the Section 338 Elections on a timely basis
and agree to cooperate in good faith with each other in the preparation and
timely filing of any Tax Returns required to be filed in connection with the
making of the Section 338 Elections, including the exchange of information and
the joint preparation (subject to Section 5.12(b) hereof) and filing of IRS Form
8023 and related schedules. The Stockholder will pay any and all Taxes
attributable to the actual sale of the Company's Shares and/or the deemed asset
sale resulting from the making of the Section 338 Elections and will indemnify
SmarTalk in accordance with Section 9.4 against any adverse consequences arising
out of any failure to pay such Taxes.

            (b)   SmarTalk and the Stockholder shall jointly determine the
liabilities of the Company, and allocate the Purchase Price, such liabilities,
and other relevant items in accordance with section 338 of the Code and the
Treasury Regulations promulgated thereunder (such determination and allocation,
the "Section 338 Determinations"). If SmarTalk and Stockholder are unable to
agree with respect to any Section 338 Determination within one-hundred-twenty
(120) days after the Closing Date, an independent accounting firm (the
"Arbiter"), mutually selected and jointly engaged by the parties, shall resolve
the matter and the Arbiter's determination shall be binding on the parties and
reflected on Form 8023 and related schedules. Expenses of the Arbiter incurred
in connection with such dispute shall be shared equally by the parties hereto.
Parent, the Stockholder and SmarTalk agree to act in accordance with the Section
338 Determinations in the preparation and filing of all Tax Returns and in the
course of any tax audit, appeal, or litigation relating thereto, except as may
be required by a Final Determination with respect to any such issue. Upon
payment of any indemnification obligations hereunder resulting in an adjustment
of the "modified adjusted deemed sales price," the Section 338 Determinations
shall be appropriately adjusted in accordance with the procedures described in
this Section 5.12(b).

            (c)   The Stockholder shall prepare in a manner consistent with past
practice (except for changes caused by a material change in fact or law that
would not have a material effect on the relevant tax liability) and file or
cause to be filed, all Tax Returns (whether separate or consolidated, combined,
group or unitary Tax Returns that include the Company) that are required to be
filed (subject to permitted extensions) with respect to all Taxable Periods
ending on or before the date of the Initial Closing; and, the Stockholder shall
pay or cause to be paid all Taxes shown as due, or required to be shown as due,
on such Tax Returns and shall be entitled to any refunds relating to such Tax
Returns.


                                       23
<PAGE>   29
            (d)   SmarTalk shall prepare and file (or cause to be prepared and
filed) all Tax Returns of or including the Company other than those described in
Section 5.12(c) hereof. The Stockholder shall pay to SmarTalk at least five days
prior to the date such amounts are due to the relevant taxing authority, the
portion of Taxes shown to be due on such Tax Returns which is apportioned to any
taxable period ending on or before the Closing Date including, without
limitation, the Interim Period, provided, however, that SmarTalk shall deliver
copies of all such Tax Returns that affect the Stockholder's liability for Taxes
hereunder to the Stockholder at least 15 days prior to the due date for filing,
and the Stockholder shall have the right to review any such Tax Returns before
they are filed (although the failure to provide such returns within that time
shall not relieve the Stockholder's liability for such Taxes). If the
Stockholder disagrees with SmarTalk's determination of the Taxes for which the
Stockholder is responsible hereunder, the Stockholder shall give written notice
to SmarTalk of such disagreement within five days of SmarTalk's delivery of the
applicable Tax Return to the Stockholder. If the Stockholder and SmarTalk are
unable to settle or compromise such dispute within three days after the
Stockholder's notice of disagreement, the Stockholder's and SmarTalk's
accounting firms shall select a third accounting firm, subject to the approval
of both the Stockholder and SmarTalk, to determine the disputed amount, and the
determination of such third accounting firm shall be final. In the event the
third accounting firm determines that the Stockholder owes SmarTalk any portion
of the disputed amount, the Stockholder shall bear the portion of the costs of
the third accounting firm determined by multiplying such costs by a fraction the
numerator of which is the additional amount which such third accounting firm
determines that the Stockholder owes to SmarTalk and the denominator of which is
the disputed amount. SmarTalk shall bear all costs of the third accounting firm
that are not paid by the Stockholder pursuant to the preceding sentence.

            (e)   Notwithstanding any other provision of this Agreement, all
transfer, documentary, sales, use, registration and other such Taxes (including,
without limitation, all applicable real estate transfer or gains taxes and stock
transfer Taxes), any penalties, interest and additions to Tax and fees incurred
in connection with this Agreement and the transactions contemplated hereby shall
be paid by the Stockholder. Each party to this Agreement shall cooperate in the
timely making of all filings, returns, reports and forms as may be required in
connection therewith.

            (f)   For purposes of apportioning income Taxes (and, except as
otherwise provided hereinbelow, other Taxes imposed on a transactional basis) to
any Short Period or Interim Period, the parties hereto shall treat the date of
the Initial Closing as the last day of such Period (i.e., the parties shall
"close the books" on such date) and shall elect to do so if permitted by
applicable law. Except for purposes of Section 9.4 hereof, all federal
communications excise Taxes and all sales, use and excise (and similar) Taxes
imposed upon the sale or use of prepaid calling cards shall be apportioned to
the Interim Period only to the extent that such Taxes relate to calls made on or
before the Closing Date. The portion of all ad 


                                       24
<PAGE>   30
valorem (e.g., property) and all other similar Taxes apportioned to the Interim
Period shall be equal to the amount of such Taxes imposed for the entire Taxable
Period which includes the Interim Period multiplied by a fraction, the numerator
of which is the number of days in the Interim Period and the denominator of
which is the number of days in the entire Taxable Period which includes the
Interim Period.

            (g)   All contracts, agreements (other than this Agreement), or
intercompany account systems between or involving the Company and any other
members of the Parent Group under which the Company may at any time have an
obligation to share the payment of any portion of a Tax or the right to receive
any payment (or any amount calculated with reference to any portion of a Tax)
shall be terminated with respect to the Company as of the date of the Initial
Closing, and the Company and all other members of the Parent Group shall
thereafter be released from any liability thereunder.

            (h)   After the Initial Closing, the parties hereto shall (i)
provide, and shall cause each of their affiliates to provide, to the other party
and its affiliates (at the expense of the requesting party) such information
(including but not limited to accounting and tax books and records) relating to
the Company as such party may reasonably request with respect to Tax matters;
and (ii) cooperate with each other in the conduct of any audit, litigation or
other proceeding with respect to any Tax involving the Company and shall retain
or cause to be retained all books and records pertinent to the Company for each
Taxable Period or portion thereof ending on or prior to the date of the Initial
Closing until one year after the expiration of the applicable statute of
limitations (giving effect to any and all extensions and waivers). At the
request and reasonable expense of the Stockholder, SmarTalk shall cause the
Company to prepare and provide to the Stockholder packages of tax information
materials relating to the Company including but not limited to federal and state
income and foreign tax information (the "Tax Packages"), which shall be
completed in accordance with past practice (except for changes caused by a
material change of fact or law that would not have a material effect on the
relevant tax liability) together with relevant work papers, for purposes of
preparing all Tax Returns with respect to which the Stockholder has filing or
tax payment responsibility, together with all other relevant materials and
information reasonably requested by the Stockholder for these purposes. SmarTalk
shall cause the Tax Packages for all such Taxable Periods (or portions thereof)
of the Company to be delivered to the Stockholder no later than 30 business days
prior to the due date for filing such Tax Returns.

            (i)   If any party hereto receives any written notice from any
taxing authority proposing any adjustment to any Tax relating to the Company for
which another party may have liability after the Initial Closing, such party
shall give prompt written notice thereof to the party which may have liability,
which notice shall describe in detail such proposed adjustment. The receipt of
any such notice 


                                       25
<PAGE>   31
from a taxing authority by any member of the Parent Group shall be deemed to
constitute receipt thereof by Stockholder.

            (j)   At the Initial Closing, the Stockholder shall deliver to
SmarTalk, pursuant to section 1445(b)(2) of the Code and Treas. Reg.
1.1445-2(b)(2) a duly executed certification of non-foreign status. Such
certification shall conform to the model certification provided in Treas. Reg.
1.1445-2(b)(2)(iii)(B).

            (k)   The Stockholder agrees that Parent shall take all actions that
Parent is required to take pursuant to this Agreement with respect to the
Section 338 Elections.

            (l)   SmarTalk and the Stockholder agree that, for federal income
tax purposes, SmarTalk will become the owner of all of the Shares on the Closing
Date and accordingly agree to treat the transactions contemplated hereby in a
manner consistent with that determination for all federal income tax purposes.

            5.13. Regulatory and Other Authorizations. Each of the Stockholder,
the Company and SmarTalk shall as promptly as practicable prepare, submit and
file (or cause to be prepared, submitted and filed) all applications, notices
and requests for, and shall use all reasonable efforts to obtain as promptly as
practicable (or cause to be obtained as promptly as practicable), all
authorizations, consents, orders and approvals of all Governmental Authorities
and officials that may be or become necessary on each of their parts,
respectively, for their execution and delivery of, and the performance of their
obligations pursuant to, this Agreement, and will cooperate fully with each
other in promptly seeking to obtain all such authorizations, consents, orders
and approvals. Each of the Stockholder, the Company and SmarTalk shall use all
reasonable efforts to obtain (or cause to be obtained), to the extent available,
confidential treatment by each such Governmental Authority and official of any
filing made in connection with obtaining all such authorizations, consents,
orders and approvals. Without limiting the foregoing, each party hereto agrees
to make an appropriate filing, if necessary, pursuant to the HSR Act with
respect to the transactions contemplated by this Agreement within 20 business
days of the date hereof and to supply as promptly as practicable to the
appropriate Governmental Authorities any additional information and documentary
material that may be requested pursuant to the HSR Act.

            5.14. Co-Marketing and Technology Agreement. On or prior to the
Initial Closing, the Stockholder and SmarTalk shall each execute and deliver, or
cause to be executed and delivered, a Pre-Paid Telephone Card Co-Marketing and
Technology Agreement in the form attached as Exhibit A.

            5.15. Carrier Agreement. On or prior to the Initial Closing, the

to be executed and delivered, a Carrier Agreement in the form attached as

<PAGE>   32
            5.16. Transition Agreement. On or prior to the Initial Closing, the

delivered, a Non-Competition Agreement in the form attached as Exhibit D.
Notwithstanding the foregoing, the Stockholder shall be entitled to grant
licenses or other rights to third parties, from time to time and in the
Stockholder's sole discretion and with no accounting or other obligation to
SmarTalk, under technologies described in any and all patents and patent
applications owned or hereafter acquired by the Stockholder relating to prepaid
telephone cards and related technology. The parties agree that it shall not be a
violation of this Agreement, including the attached Non-Competition Agreement,
or of any other agreements among the parties for the Stockholder to enter into
agreements with third parties granting licenses or other rights to such third
parties in the aforementioned patents, patent applications and/or related
technologies.

            5.18. License of Patents. The Stockholder hereby grants to SmarTalk,
the Company and its Affiliates a perpetual, fully paid up, royalty-free,
nonexclusive, non-sublicensable, non-transferable license to use the inventions,
technology and all other subject matter disclosed in the patents and patent
applications set forth in Schedule 5.18, including all patents resulting from
any such patent applications in the U.S. and in any foreign countries, as well
as (x) all inventions and technology related to or based on the foregoing made
at any time by the Stockholder or any of its Affiliates, (y) all improvements in
or to any of the foregoing made at any time by or on behalf of the Stockholder
or any of its Affiliates, and (z) all know-how, ideas, inventions, processes and
trade secrets relating thereto in the possession at any time of any of the
foregoing persons (such patents, patent applications, technology and inventions,
together with the items specified in clauses (x), (y) and (z) above,
collectively, the "Technology"). The Stockholder retains the sole and exclusive
right to prosecute, in the Stockholder's sole discretion, any and all such
patent applications including, but not limited to, the right to file
continuation, divisional, reissue and other patent applications based on the
same or similar technology and the right to cease prosecution of any or all
applications or to cease to maintain any issued patents in any country at any
time without notice to SmarTalk. The Stockholder also retains the sole and
exclusive right to sue for infringement and collect damages, including any and
all past infringements and damages resulting from any of the aforementioned
patents. Notwithstanding the foregoing, in the event the Stockholder fails to
exercise its rights to prosecute and/or sue, the Company, upon 30 days' prior
written notice to the Stockholder, shall have the right to do so at its own
expense, and the Stockholder shall cooperate in connection therewith, at no
expense to the Stockholder. The Stockholder represents and warrants that the
patents and patent applications set forth in Schedule 5.18 represent all of the
patents and patent applications owned by the Stockholders or its Affiliates 


                                       27
<PAGE>   33
used in the business of the Company as currently conducted. The Stockholder, on
its own behalf and on behalf of its Affiliates, hereby releases the Company,
SmarTalk and their respective Affiliates from and against any liability
whatsoever, to the Stockholder or any of its Affiliates, in respect of the use
anywhere in the world by such persons, prior or subsequent to the Initial
Closing, of any of the Technology, whether in violation or infringement of any
patents at any time existing or otherwise. Without limiting the generality of
the foregoing, such release shall apply with respect to Technology which does
not exist on the date hereof. For purposes of this Section 5.18, "Affiliates" of
SmarTalk shall mean and include entities which at any time in the future
control, are controlled by or are under common control with SmarTalk. Subject to
Section 3.15, the Stockholder does not represent or warrant the patentability,
validity or enforceability of any of the patents or patent applications set
forth in Schedule 5.18.

            5.19. Other Assignments; License. (a) At the Initial Closing, the
Stockholder will deliver to the Company, SmarTalk and/or one or more of their
Affiliates, as directed by SmarTalk, assignments in such form as SmarTalk shall
reasonably request (including without limitation in such form as shall be
appropriate for recordation in the Patent and Trademark Office and/or the
Copyright Office) of all Intellectual Property, other than the patents referred
to in Section 5.18 (the "Patents"), owned by the Stockholder or any of its
Affiliates and used in the business of the Company as of the date hereof, such
assignments to include, without limitation, assignments of all trademarks,
service marks, computer software, copyrights and all rights to all intellectual
property used in connection with the Company's existing arrangements with the
U.S. Postal Service, as well as any third party rights previously obtained by
the Stockholder or any of its Affiliates in connection with the foregoing. To
the extent that such Intellectual Property is not owned by Stockholder or any of
its Affiliates, Stockholder will grant to SmarTalk, the Company and its
Affiliates a perpetual, fully paid up, royalty-free, nonexclusive,
non-sublicensable, non-transferable license or sublicense to such Intellectual
Property. Notwithstanding the foregoing provisions of this clause (a), the
Stockholder shall not be obligated to grant to SmarTalk, the Company and their
Affiliates such a license or sublicense unless the terms of the underlying
license with the third party from which Stockholder or its Affiliates derives
its rights would permit a license or sublicense to be granted to SmarTalk, the
Company or their Affiliates. The Stockholder hereby represents and warrants that
no third party consents, including that of the U.S. Postal Service, are required
in connection with any of the foregoing assignments. From and after the Initial
Closing, neither the Stockholder nor any of its Affiliates shall have any right
to use any materials assigned hereunder, nor any of the Intellectual Property
(other than the Patents).

            (b)   At the Initial Closing, the Stockholder agrees that it (and/or
its appropriate Affiliates) will deliver to SmarTalk, the Company and their
Affiliates, as directed by SmarTalk, (i) an assignment in such form as SmarTalk
shall reasonably request (including without limitation in such form as shall be
appropriate for 


                                       28
<PAGE>   34
recordation in the Patent and Trademark Office and/or the Copyright Office) of
all of its (and/or its Affiliates') rights in and to the trademark PHONEFUNDS(R)
and all rights related thereto and (ii) a license agreement whereby the Company
and its Affiliates will have the right to use the service mark AMERICAN
EXPRESS(R) on all advertising and other materials in the possession of the
Company immediately prior to the Initial Closing on which such mark appears, in
the manner currently used by the Company, until the Company and/or its
Affiliates exhaust such supply of such materials; provided, that with respect to
this clause (ii) SmarTalk shall use its reasonable efforts to cause such
material in the possession of it or any of its Affiliates to be destroyed not
later than June 1, 1998 to the extent not theretofore used.

            5.20. Company Name. Promptly after the Initial Closing, SmarTalk
will change or cause to be changed the Company's name to a name that does not
use the words "American Express" or any derivative thereof. 

            5.21. Escrow Agreement. On or prior to the Initial Closing, the
Stockholder and SmarTalk shall each execute and deliver, or cause to be executed
and delivered, an Escrow Agreement in the form attached as Exhibit F.

                                INDEMNIFICATIONS

            9.1.  Indemnification by the Stockholder. The Stockholder hereby
agrees to indemnify and hold harmless SmarTalk and its directors, officers,
agents and employees (each, a "SmarTalk Indemnified Person") from and against
and to pay any losses, claims, damages or liabilities (or actions or proceedings
in respect thereof) ("Damages") to which such SmarTalk Indemnified Person may
become subject which relate to, result from or arise from (i) without
duplication for the matters subject to Section 9.4 hereof, any
misrepresentation, or breach of warranty or covenant made or to be performed on
the part of such Stockholder or the Company under this Agreement, and (ii) any
arrangement between Stockholder or any of its Affiliates and Global One
Communications, LLC or any of its Affiliates, and, in the case of each of
clauses (i) and (ii), will reimburse any SmarTalk Indemnified Person for all
expenses (including reasonable counsel and expert fees) as they are incurred by
any such SmarTalk Indemnified Person in connection with any such
misrepresentation or breach of warranty or covenant or investigating, preparing
or defending any such action or proceeding, whether pending or threatened, and
whether or not such SmarTalk Indemnified Person is a party hereto; provided,
however, that the Stockholder shall not be required to indemnify or reimburse
SmarTalk Indemnified Persons for amounts exceeding the Purchase Price. 


                                       34
<PAGE>   40
The Stockholder will not be responsible for any Damages or expenses to the
extent that a court of competent jurisdiction shall have finally determined that
such Damages or expenses resulted primarily from such SmarTalk Indemnified
Person's bad faith or gross negligence or material breach of this Agreement.
Notwithstanding the foregoing, and except as provided elsewhere in this
Agreement, the Stockholder shall indemnify and hold harmless SmarTalk
Indemnified Persons from and against any Damages which relate to, result from or
arise from the conduct of the business of the Company for any period prior to
the Initial Closing.

            9.2.  Indemnification by SmarTalk. SmarTalk hereby agrees to
indemnify and hold harmless the Stockholder and its directors, officers, agents
and employees (each, a "Stockholder Indemnified Person") from and against and to
pay any Damages to which such Stockholder Indemnified Person may become subject
which relate to, result from or arise from any misrepresentation, or breach of
warranty or covenant made or to be performed on the part of SmarTalk under this
Agreement, and will reimburse any Stockholder Indemnified Person for all
expenses (including reasonable counsel and expert fees) as they are incurred by
any such Stockholder Indemnified Person in connection with any such
misrepresentation or breach of warranty or covenant or investigating, preparing
or defending any such action or proceeding, whether pending or threatened, and
whether or not such Stockholder Indemnified Person is a party hereto; provided,
however, that SmarTalk shall not be required to indemnify or reimburse
Stockholder Indemnified Persons for amounts exceeding the Purchase Price.
SmarTalk will not be responsible for any Damages or expenses to the extent that
a court of competent jurisdiction shall have finally determined that such
Damages or expenses resulted primarily from such Stockholder Indemnified
Person's bad faith or gross negligence or material breach of this Agreement.
Notwithstanding the foregoing, and except as provided elsewhere in this
Agreement, SmarTalk shall indemnify and hold harmless Stockholder Indemnified
Persons from and against any Damages which relate to, result from or arise from
the conduct of the business of the Company for any period after the Initial
Closing.

            9.3.  Indemnification Procedure. (a) The party or parties being
indemnified are referred to herein as the "Indemnified Party" and the
indemnifying party is referred to herein as the "Indemnifying Party;"

            (b)   The Indemnified Party shall give prompt written notice
("Indemnification Notice") to the Indemnifying Party after discovery by the
Indemnified Party of any matters giving rise to a claim for indemnification or
reimbursement under this Agreement; provided, however, that if no prejudice
results from a failure to deliver prompt notice of a claim, no penalty shall be
exacted therefor and the Indemnified Party shall continue to be entitled to
indemnification;

            (c)   In the event that the Indemnifying Party advises the
Indemnified Party that the Indemnifying Party will contest a claim for
indemnification hereunder, 


                                       35
<PAGE>   41
or fails, within 30 days of receipt of any Indemnification Notice to notify, in
writing, the Indemnified Party of its election to defend, settle or compromise,
at its sole cost and expense, any action or claim (or discontinues its defense
at any time after it commences such defense), then the Indemnified Party may, at
its option, defend, settle or otherwise compromise or pay such action or claim.
In any event, unless and until the Indemnifying Party elects in writing to
assume and does so assume the defense of any such claim or action, the
Indemnified Party's costs and expenses arising out of the defense, settlement or
compromise of any such action or claim shall be Damages subject to
indemnification hereunder;

            (d)   The Indemnified Party shall reasonably cooperate with the
Indemnifying Party in connection with any negotiation or defense of any such
action or claim by the Indemnifying Party and shall furnish to the Indemnifying
Party all information reasonably available to the Indemnifying Party which
relates to such action or claim. The Indemnifying Party, if the defending party,
shall keep the Indemnified Party fully apprised at all times as to the status of
the defense or any settlement negotiations with respect thereto. If the
Indemnifying Party elects to defend any such action or claim, then the
Indemnified Party shall be entitled to participate in such defense with counsel
of its choice at its sole cost and expense. If the Indemnifying Party does not
assume the defense, the Indemnified Party shall use reasonable efforts to keep
the Indemnifying Party apprised at all times as to the status of the defense.
Payment of indemnification amounts hereunder shall be made to the person
specified by the Indemnified Party. Anything in this Section 9.3 to the contrary
notwithstanding, no person shall, without each of the parties' prior written
consent, settle or compromise any claim or consent to entry of any judgment in
respect thereof which imposes any future obligation on any other party or which
does not include, as an unconditional term thereof, the giving by the claimant
or the plaintiff to the other parties, a release from all liability in respect
of such claim.

            9.4.  Tax Indemnifications. (a) The Stockholder shall indemnify,
defend and hold harmless SmarTalk, the Company and their respective officers,
directors, employees and agents (each, a "Tax Indemnitee") from and against, and
shall promptly reimburse each Tax Indemnitee for, any and all Taxes (including,
without limitation, those attributable to a lack of basis allocable to an
amortizable or depreciable asset, reasonable expenses of investigation and
reasonable attorneys' and accountants' fees and expenses in connection with any
action, suit or proceeding) actually incurred or suffered at any time by any Tax
Indemnitee arising out of or attributable to: (i) any misrepresentation,
inaccuracy or breach of any representation, warranty, covenant, agreement or
promise related to Taxes by the Parent, such Stockholder and/or the Company
contained in this Agreement (or in any certificate, document, list or schedule
delivered to SmarTalk by the Parent, the Stockholder or the Company hereunder);
(ii) any and all unpaid Taxes for any Taxable Period, or portion thereof, ending
on or before the date of Initial Closing; (iii) any and all unpaid Taxes,
whether determined on a separate, consolidated, combined, or unitary basis,
including any penalties and interest in respect thereof, 


                                       36
<PAGE>   42
of or relating to the Company: (A) pursuant to Treas. Reg. Section 1.1502-6 or
any comparable provision of state, local, or foreign law with respect to any
Taxable Period beginning before the Closing Date; or (B) pursuant to any
guaranty, indemnification, Tax sharing, or similar agreement made on or before
the Closing Date relating to the sharing of liability for, or payment of, Taxes
with respect to any Taxable Period, or portion thereof ending on or before the
Closing Date; or (iv) any and all Taxes attributable to or resulting from the
Section 338 Elections. Notwithstanding the foregoing, to the extent the
Stockholder has made payments pursuant to Section 2.3 of this Agreement for
federal excise and/or state and local sales/use, excise or other similar Tax
liability on unused calling time, any indemnification under this Section 9.4
with respect to Taxes on such unused calling time shall be reduced by any amount
paid under Section 2.3 with respect to such Taxes so as to avoid double payment
by the Stockholder for this liability.

            (b)   The Indemnifying Party and its duly appointed representatives
shall have the sole right to negotiate, resolve, settle or contest any claim for
Tax made by a taxing authority with respect to which the Indemnifying Party has
agreed to indemnify a Tax Indemnitee under this Section 9.4. If the Indemnifying
Party does not assume the defense of a claim for the Tax made by a taxing
authority with respect to which the Indemnifying Party has indemnified a Tax
Indemnitee under this Section 9.4, the Tax Indemnitee may defend the same at the
reasonable expense of the Indemnifying Party in such manner as it may deem
appropriate, including, but not limited to, settling such audit or proceeding
without the consent of the Indemnifying Party.

     jurisdiction in the United States or other United States governmental body
     shall have issued an order, decree or ruling or taken any other action
     restraining, enjoining or otherwise prohibiting the transactions 


                                       37
<PAGE>   43
     contemplated hereby and such order, decree, ruling or other action shall
     have become final and non-appealable.

            10.2. Notice of Abandonment. In the event of any termination
pursuant to Section 10.1, written notice shall forthwith be given to the other
party hereto except with respect to a termination pursuant to Section 10.1(a).

            10.3. Mandatory Termination. If the Initial Closing has not occurred
by March 31, 1998 this Agreement shall automatically terminate and no longer be
of any force or effect, unless extended by the written agreement of SmarTalk and
the Stockholder.

            10.4. Effect of Termination. Except for the confidentiality
obligations contained in Section 5.1 and expense obligations in Section 11.1
hereof, upon the termination of this Agreement pursuant to Section 10.1 or
Section 10.3 hereof, this Agreement shall forthwith become null and void, and no
party hereto or any of its officers, directors or shareholders shall have any
liability hereunder.

(or the modification to conform with such laws or public policies) of any

invalid or unenforceable in whole or in part, this Agreement shall be deemed
amended to delete or modify, in whole or in part as necessary, the invalid or
unenforceable provisions or portions thereof and to alter the remainder of this

similar as possible to such illegal, invalid or unenforceable provision and be
legal, valid and enforceable. Further, should any provision contained in this
