                           SAN ANTONIO, TEXAS  78249


Dear Shareholders:

     Your approval is requested for the following transactions which American
Telesource International Inc. (the "Company" or "ATSI") is proposing to its
shareholders at the special meeting of shareholders.

SHARE CONSOLIDATION.  The Board of Directors will ask shareholders to pass (i) a
special resolution, with or without variation, subject to requisite regulatory
approval, authorizing and approving the filing of Articles of Amendment
consolidating the issued and outstanding common shares (the "Common Shares") of
the Company in its capital on the basis of one post-consolidation common share
(a "Post-Consolidation Common Share") for each two pre-consolidation common
shares ("Pre-Consolidation Common Shares") (the "First Consolidation") and (ii)
a special resolution, with or without variation, subject to requisite regulatory
approval, authorizing and approving the filing in the future of one additional
charter amendment (without further action of shareholders) further
consolidating, on a one-for-two basis, the issued and outstanding Common Shares,
or shares of ATSI Merger Corp. Common Stock (as defined herein) in the event the
Merger (as defined herein) occurs, if the Board of Directors in its sole
discretion deems such further consolidation necessary to satisfy the minimum per
share price requirements for listing on the Nasdaq National Market, Nasdaq
SmallCap Market or another securities market or exchange (the "Second
Consolidation" and, together with the First Consolidation, the "Consolidation").

     The Board of Directors believes that the Consolidation is in the best
interests of the shareholders because over the long term the Company will have
greater flexibility with respect to future equity financings which will be
necessary to develop the Company's business. Furthermore, the Company, or ATSI
Merger Corp. (as defined herein) in the event the Merger (as defined herein)
occurs, may in the future apply for listing on the Nasdaq National Market,
Nasdaq SmallCap Market or another securities market or exchange, which listing
may require the satisfaction of certain conditions, including minimum per share
price requirements. If such resolution is approved, it is currently anticipated
that the Articles of Amendment effecting the First Consolidation will be filed
regardless of whether the Domestication and Merger are effected and shareholders
will be required to surrender their current certificates representing Pre-
Consolidation Common Shares in exchange for certificates representing Post-
Consolidation Common Shares. Appropriate transmittal forms will be sent to
shareholders for this purpose. Prior to a share certificate being surrendered,
such share certificate will represent whole shares of the Company on a post-
consolidated basis, being in an amount equal to one-half of the amount
represented on the original share certificate.

DOMESTICATION.  The Board of Directors will submit a proposal to domesticate the
Company from a corporation existing under the laws of the Province of Ontario,
Canada to a corporation existing under the laws of the State of Delaware, United
States of America (the "Domestication"). If approved by at least two-thirds of
the votes cast by holders of the Common Shares represented in person or by proxy
at the meeting, the Domestication will result in a change in the Company's
jurisdiction of incorporation from the Province of Ontario to the State of
Delaware and will also result in the adoption of a new certificate of
incorporation for the Company, which will govern the Company under Delaware law.
If approved by the shareholders and subject to requisite regulatory approval, it
is anticipated that the Domestication will become effective on or about
__________ ____, 1996, or as soon as practicable after the special meeting of
shareholders.

MERGER.  If the Domestication is approved and becomes effective, the
shareholders of the Company, after it has been domesticated in Delaware, will be
asked to approve by written consent the merger (the "Merger") of the Company
with and into its wholly-owned subsidiary, ATSI Merger Corp. ("ATSI Merger
Corp.") pursuant to the laws of the State of Delaware. Such written consent will
be executed pursuant to proxies solicited hereby (the "Consent"). Accordingly,
no shareholder meeting will be held with respect to the Merger proposal. If the
Merger is completed, holders of Common Shares will receive one share of Common
Stock,
<PAGE>
 
$0.001 par value per share, of ATSI Merger Corp. ("ATSI Merger Corp. Common
Stock") for each Common Share held immediately prior to the Merger. In addition,
all warrants of ATSI outstanding immediately prior to the Merger will become
obligations of ATSI Merger Corp. upon consummation of the Merger. If approved by
the shareholders of ATSI pursuant to the Consent, immediately following the
Merger the name of the surviving company will change to American Telesource
International, Inc. or such other name as may be authorized by the Board of
Directors of ATSI. It is anticipated that the Merger, if approved by the
shareholders of ATSI pursuant to the Consent, will also become effective on or
about __________ ____, 1996, or as soon as practicable after the completion of
the Domestication.

     The Board of Directors has reserved the right to terminate or abandon the
Consolidation, Domestication and/or the Merger at any time prior to the
effectiveness of each, notwithstanding shareholder approval, if the Board of
Directors determines for any reason that the consummation of the Consolidation,
Domestication and/or the Merger would be inadvisable or not in the best
interests of the Company or its shareholders.

     For a summary of the principal income tax consequences of the
Consolidation, Domestication and Merger to United States shareholders and
warrantholders, Canadian shareholders and warrantholders, and the Company, see
"Canadian and United States Income Tax Considerations" contained in the Circular
and Proxy Statement/Prospectus (the "Prospectus").

1996 OPTION PLAN.  The Board of Directors will submit the American Telesource
International Inc. 1996 Stock Option Plan (the "1996 Option Plan") to
shareholders for their approval. If approved by at least a majority of the votes
cast by holders of the Common Shares represented in person or by proxy at the
meeting, excluding votes cast by directors, executive officers and beneficial
owners of 10% or more of the Common Shares, the 1996 Option Plan provides that
options to purchase up to 4,000,000 Common Shares may be granted to employees
and directors of, and consultants and advisors to, the Company or any subsidiary
corporation or entity. Such number of shares shall be subject to adjustment to
2,000,000 shares in the event that the proposed one-for-two reverse stock split
of the Common Shares pursuant to the First Consolidation is approved by the
shareholders at the meeting. The 1996 Option Plan is intended to promote the
interest of the Company and its shareholders by providing an effective means to
attract, retain and increase the commitment of certain individuals and to
provide such individuals with additional incentive to contribute to the success
of the Company.

     THE ONLY WAY A HOLDER OF COMMON SHARES CAN EXPRESS HIS APPROVAL OF THE
MERGER IS BY EXECUTING THE PROXY AUTHORIZING THE PERSONS NAMED THEREIN TO
APPROVE THE MERGER BY MEANS OF THE CONSENT. THE FAILURE TO GRANT A PROXY OR THE
WITHHOLDING OF AUTHORITY TO EXECUTE THE CONSENT HAS THE SAME EFFECT AS A VOTE
"AGAINST" THE MERGER. FURTHERMORE, A PROXY AUTHORIZING THE EXECUTION OF THE
CONSENT IS VALID ONLY IF THE PERSON EXECUTING THE PROXY REMAINS A HOLDER OF
RECORD OF THE SHARES REPRESENTED THEREBY AT THE TIME THE DOMESTICATION BECOMES
EFFECTIVE AND THE CONSENT IS EXECUTED. THEREFORE, IF YOU WISH TO HAVE YOUR
SHARES REPRESENTED IN THE APPROVAL OF THE MERGER, WE URGE YOU NOT TO SELL OR
TRANSFER ANY SHARES PRIOR TO THE EFFECTIVENESS OF THE DOMESTICATION.

     IF THE MERGER IS COMPLETED, SHAREHOLDERS WILL BE REQUIRED TO SURRENDER
THEIR CURRENT CERTIFICATES REPRESENTING COMMON SHARES IN EXCHANGE FOR
CERTIFICATES REPRESENTING THE APPROPRIATE NUMBER OF SHARES OF ATSI MERGER CORP.
COMMON STOCK. IF THE MERGER IS NOT COMPLETED BUT THE FIRST CONSOLIDATION IS
COMPLETED, THEN SHAREHOLDERS WILL BE REQUIRED TO SURRENDER THEIR CURRENT
CERTIFICATES REPRESENTING PRE-CONSOLIDATION COMMON SHARES IN EXCHANGE FOR
CERTIFICATES REPRESENTING THE APPROPRIATE NUMBER OF POST-CONSOLIDATION COMMON
SHARES. Appropriate transmittal forms will be sent to shareholders for these
purposes. After the First Consolidation and the Merger occur but before a stock
certificate for Pre-Consolidation Common Shares is surrendered, such certificate
will represent Post-Consolidation Common Shares and whole shares of ATSI Merger
Corp. Common Stock in an amount equal to the number of Post-Consolidation Common
Shares (deemed to be represented) (or formerly represented) thereby,
respectively. If both the First Consolidation and Merger occur, only one
exchange will be required. If the Domestication
<PAGE>
 
occurs but the Merger does not, every holder of Common Shares will be required
to surrender the certificates representing such shares in order for such
certificates to be replaced with new certificates of ATSI which conform to the
requirements of Delaware law.

     THE PROSPECTUS PROVIDES A DETAILED DESCRIPTION OF THE CONSOLIDATION,
DOMESTICATION, MERGER AND 1996 OPTION PLAN AND OTHER INFORMATION TO ASSIST YOU
IN CONSIDERING THE MATTERS TO BE VOTED ON. WE URGE YOU TO REVIEW THIS
INFORMATION CAREFULLY AND, IF YOU REQUIRE ASSISTANCE, TO CONSULT WITH YOUR
FINANCIAL, TAX OR OTHER PROFESSIONAL ADVISORS.

     FOR THE REASONS SET FORTH IN THE PROSPECTUS, YOUR BOARD OF DIRECTORS
UNANIMOUSLY BELIEVES THAT THE PROPOSED CONSOLIDATION, DOMESTICATION AND MERGER
AND THE ADOPTION OF THE 1996 OPTION PLAN ARE IN THE BEST INTERESTS OF THE
COMPANY AND ALL OF ITS SHAREHOLDERS. WE THEREFORE STRONGLY URGE YOU TO VOTE
"FOR" THE CONSOLIDATION, DOMESTICATION AND MERGER AND 1996 OPTION PLAN.

                                 Very truly yours,



                                 ARTHUR L. SMITH

                       12,487,638 SHARES OF COMMON STOCK
                  AND 5,009,963 WARRANTS OF ATSI MERGER CORP.

                             ____________________


     This Circular and Proxy Statement/Prospectus (this "Prospectus") is being
furnished as a management proxy circular in connection with the solicitation by
the Board of Directors and management of American Telesource International Inc.
("ATSI") of proxies for use at the Special Meeting of Common Shareholders (the
"Meeting") or any adjournment(s) thereof. The Meeting will be held on __________
___, 1996 at the time, place and for the purposes set forth in the Notice of
Meeting.

     This Prospectus constitutes the Prospectus of ATSI under the United States
Securities Act of 1933, as amended (the "Securities Act"), with respect to (i)
19,965,312 Common Shares (the "Common Shares") of ATSI, (ii) 5,009,963 warrants
("ATSI Warrants") of ATSI, and (iii) 5,009,963 Common Shares issuable upon the
exercise of the ATSI Warrants, to be issued to or held by holders of shares in
the capital and warrants, as applicable, of ATSI as a result of its
domestication from the Province of Ontario to the State of Delaware. This
Prospectus also constitutes the Prospectus of ATSI Merger Corp. ("ATSI Merger
Corp." and, together with ATSI, the "ATSI Companies"), a Delaware corporation
and a wholly-owned subsidiary of ATSI, under the Securities Act with respect to
(i) 9,982,656 shares of Common Stock, par value $0.001 per share ("ATSI Merger
Corp. Common Stock"), of ATSI Merger Corp., (ii) 5,009,963 warrants ("ATSI
Merger Corp. Warrants") of ATSI Merger Corp., and (iii) 2,504,982 shares of ATSI
Merger Corp. Common Stock issuable upon the exercise of the ATSI Merger Corp.
Warrants, of ATSI Merger Corp. to be issued to or held by holders of Common
Shares and ATSI Warrants, as applicable, as a result of the merger of ATSI with
and into ATSI Merger Corp. To effect such domestication and merger, ATSI first
will be domesticated (the "Domestication") as a corporation organized under the
General Corporation Law of the State of Delaware, as amended (the "DGCL"), and
then will be merged (the "Merger") with and into ATSI Merger Corp. See
"Domestication and Merger."

     Prior to the Domestication and the Merger, the Company intends to effect a
consolidation of the Common Shares on the basis of one post-consolidation common
share ("Post-Consolidation Common Share") for each two pre-consolidation common
shares ("Pre-Consolidation Common Shares") (the "First Consolidation"), and,
after the Domestication and Merger, may effect one further consolidation, on a
one-for-two basis, of the ATSI Merger Corp. Common Stock, or Common Shares if
the Merger does not occur, if such further consolidation is necessary to satisfy
the minimum per share price requirements for listing on the Nasdaq National
Market, Nasdaq SmallCap Market or another securities market or exchange (the
"Second Consolidation" and, together with the First Consolidation, the
"Consolidation").

     At the Meeting, holders of Common Shares will also be asked to vote on the
approval and adoption of the Company's 1996 Stock Option Plan (the "1996 Option
Plan").

     Subject to certain conditions and applicable law, holders of at least
66 2/3% of the ATSI Common Shares voting in person or by proxy at the Meeting
must approve the First Consolidation, Second Consolidation and the Domestication
and holders of greater than 50% of the Common Shares voting in person or by
proxy at the Meeting, excluding votes cast by directors, executive officers and
beneficial owners of 10% or more of the Common Shares, must approve the 1996
Option Plan. Subsequent to the Domestication, approval by a majority of the
outstanding Common Shares by means of a written consent, executed pursuant to
proxies solicited hereby (the "Consent"), and by the Board of Directors, is
required to authorize the Merger. If the Domestication and the Merger are both
approved and become effective, all holders of Common Shares, except those who
have properly exercised their dissenter's rights under applicable law, will be
deemed to be stockholders of ATSI Merger Corp. as of the date when the
certificate of ownership and merger has been properly executed and duly filed
with the Secretary of State of Delaware (the "Effective Date"). See "Dissent
Rights of ATSI Shareholders." If the Domestication occurs but the Merger does
not, ATSI will be continued as a Delaware corporation. The Board of Directors of
ATSI has reserved the right to terminate or abandon the Consolidation,
Domestication and/or the Merger at any time prior to the effectiveness of each,
notwithstanding shareholder approval, if the Board of determines for any reason
that the consummation of the Consolidation, Domestication and/or Merger would be
inadvisable or not in the best interests of the Company or its shareholders. See
"Domestication and Merger" and "Canadian and United States Income Tax
Consequences."

ATSI                                    ATSI serves primarily as a holding
                                        company for its wholly-owned
                                        subsidiary, American Telesource
                                        International, Inc., a Texas
                                        corporation ("ATSI-Texas"), which
                                        provides international
                                        telecommunications networks for
                                        voice, data, fax and video
                                        transmission via satellite between
                                        the United States and Latin America
                                        and within Latin America, and call
                                        services for domestic and
                                        international long distance.  The
                                        Company has chosen to concentrate on
                                        the niche market of Latin America
                                        because it believes that the recent
                                        privatization of many of the region's
                                        major telephone companies and overall
                                        trend towards deregulation,
                                        particularly in Mexico where the
                                        Company has focused the majority of
                                        its initial efforts, present
                                        significant opportunities to provide
                                        international telecommunications
                                        services to, from and within this
                                        fast-growing market.
 
                                        ATSI was formed in May 1994 as a
                                        result of the amalgamation (the
                                        "Amalgamation") of Willingdon
                                        Resources Ltd., an Ontario
                                        corporation ("Willingdon"), with and
                                        into Latcomm International Inc., an
                                        Alberta corporation ("Latcomm")
                                        organized contemporaneously with
                                        ATSI-Texas for the purpose of
                                        acquiring ATSI-Texas.  ATSI-Texas
                                        began providing network management
                                        services in April 1994 and long
                                        distance call services in May 1994.
                                        Prior to the Amalgamation, Willingdon
                                        had been engaged in the exploration
                                        of its mining property in Northern
                                        Ontario, but was unable to prove up
                                        an economic orebody.  Willingdon had
                                        no material assets and only one
                                        material liability in the amount of
                                        approximately $55,000 at the time of
                                        the Amalgamation.

Principal Reasons for the
Consolidation                           The Board of Directors believes that
                                        the Consolidation is in the best
                                        interests of the shareholders because
                                        over the long term the Company will
                                        have greater flexibility with respect
                                        to future equity financings which may
                                        be necessary to develop the Company's
                                        business.  Furthermore, the Company,
                                        or ATSI Merger Corp. in the event the
                                        Merger occurs, may in the future
                                        apply for listing on the Nasdaq
                                        National Market, Nasdaq SmallCap
                                        Market or another securities market
                                        or exchange, which listing may
                                        require the satisfaction of certain
                                        conditions, including without
                                        limitation minimum per share price
                                        requirements.

Conditions to Consolidation             The First Consolidation and Second
                                        Consolidation must each receive the
                                        favorable vote, in person or by
                                        proxy, of the holders of at least
                                        two-thirds of the Common Shares
                                        voting on the special resolution at
                                        the Meeting.

                           DOMESTICATION AND MERGER

Domestication                           ATSI will change its jurisdiction of
                                        incorporation from Ontario to
                                        Delaware by means of a domestication
                                        under the DGCL.  Upon the
                                        effectiveness of the Domestication,
                                        ATSI will become a Delaware
                                        corporation as if it had originally
                                        been incorporated in that
                                        jurisdiction and ATSI will be
                                        discontinued in Ontario.
 
Merger                                  Subject to completion of the
                                        Domestication and the execution of
                                        consents by persons holding proxies
                                        of holders of a majority of the
                                        outstanding Common Shares, ATSI, then
                                        a Delaware corporation, will be
                                        merged with and into ATSI Merger
                                        Corp. pursuant to the DGCL and ATSI
                                        Merger Corp. will be the surviving
                                        corporation.  If approved by the
                                        shareholders of ATSI pursuant to the
                                        Consent, immediately following the
                                        Merger the name of the surviving
                                        company will change to American
                                        Telesource International, Inc. or
                                        such other name as may be authorized
                                        by the Board of Directors of ATSI.
                                        If the Merger fails to occur, ATSI
                                        will continue operating as a Delaware
                                        corporation.
 
Treatment of ATSI Common Shares         Immediately following the completion

                                        Share and ATSI Warrant will remain
                                        issued and outstanding as an
                                        equivalent security of ATSI, then a
                                        Delaware corporation.
 
                                        As a result of the Merger, (i)
                                        holders of Common Shares will receive
                                        one share of ATSI Merger Corp. Common
                                        Stock for every Common Share held by

                                        Once the First Consolidation,
                                        Domestication and Merger have been
                                        effected, each holder of certificates
                                        formerly representing Common Shares
                                        will be required to surrender such
                                        certificates for a certificate
                                        representing the appropriate number
                                        of shares of ATSI Merger Corp. Common
                                        Stock, subject to certain appraisal
                                        and other statutory rights afforded
                                        by applicable law.  If the
                                        Domestication occurs but the Merger
                                        does not, each holder of Common
                                        Shares will be requested to surrender
                                        the certificate representing such
                                        shares in order for such certificates
                                        to be replaced with new Delaware
                                        certificates of ATSI.  In either
                                        case, holders of ATSI Warrants will
                                        continue to hold such securities
                                        which will be exercisable for Common
                                        Shares or ATSI Merger Corp. Common
                                        Stock, as the case may be.  See
                                        "Description of the ATSI Merger Corp.
                                        Securities."
 
Directors and Officers                  The ATSI Board currently consists of
                                        three members, Arthur L. Smith,
                                        Murray R. Nye and John R. Moses.
                                        Upon Domestication, the ATSI Board
                                        will be increased to five members and
                                        will be divided into three classes,
                                        one class of which is to be elected
                                        each year to hold office for a
                                        three-year term and until successors
                                        are elected and qualified, as
                                        provided by the terms of the
                                        Certificate of Incorporation to be
                                        filed pursuant to the Company's
                                        Domestication into Delaware.  It is
                                        anticipated that immediately
                                        following the Domestication, John R.
                                        Moses will resign as a director of
                                        ATSI and Arthur L. Smith and Murray
                                        R. Nye, representing a majority of
                                        the directors then in office, will
                                        elect, in order to fill such
                                        vacancies and newly created

                                        then a Delaware corporation, Terry
                                        Colbert and Tomas Revesz to serve as
                                        the Class B directors and Arthur L.
                                        Smith and Murray R. Nye to serve as
                                        the Class C directors.  Messrs. Smith
                                        and Nye also intend to appoint a
                                        fifth director immediately following

Principal Reasons for the               The Domestication and Merger are
Domestication and Merger                intended to enhance shareholder value
                                        over the long-term by, among other
                                        things, improving the Company's
                                        ability and flexibility to meet its
                                        future equity and debt financing
                                        needs, enhancing the marketability of
                                        the Company's capital stock by
                                        raising the Company's profile in U.S.
                                        and international capital markets,
                                        and providing greater ease in dealing
                                        with income tax complexities
                                        associated with multi-jurisdictional
                                        operations.
 
                                        ATSI chose the State of Delaware to
                                        be its domicile because Delaware,
                                        like Ontario, has a modern and
                                        flexible corporate code.  In
                                        particular, ATSI believes that the
                                        various indemnity and exculpation
                                        provisions of the DGCL will help it
                                        to attract and retain competent
                                        directors at a time when the
                                        escalating risks and resultant costs
                                        of director liability have made it
                                        increasingly difficult for
                                        corporations to find and retain
                                        competent directors.  In addition,
                                        the State of Delaware has an active
                                        bar which is continually assessing
                                        and recommending improvements to the
                                        DGCL, and the substantial body of
                                        settled case law under the DGCL adds
                                        greater certainty in assessing risks
                                        associated with conducting business.
 
Conditions to Domestication and Merger  The Domestication must receive the
                                        favorable vote, in person or by
                                        proxy, of the holders of at least
                                        two-thirds of the Common Shares
                                        voting on the special resolution at
                                        the Meeting.  The Domestication is
                                        also conditioned upon the receipt of
                                        the requisite authorization of the
                                        Director under the OBCA (the "OBCA
                                        Director") and applicable regulatory
                                        authorities.
 
                                        The Merger is conditioned upon the
                                        effectiveness of the Domestication,
                                        the approval of the Merger by the

Timing of the Effective Date            Assuming that the First

                                        conditions thereto are satisfied, it
                                        is currently expected that the First

                                        time of a proposed listing able to
                                        satisfy applicable listing
                                        conditions, including possible
                                        minimum per share price requirements.
 
Recent Market Prices for ATSI           There is no established market in the
Common Stock                            United States for the Common Shares.
                                        However, the Common Shares are listed
                                        and traded on the Canadian Dealing
                                        Network.  The closing sales price of
                                        the Common Shares on the Canadian
                                        Dealing Network on May 15, 1996 was

Canadian Income                         Neither the Consolidation nor the
Tax Consequences                        Domestication will constitute a
                                        taxable event for the Company's
                                        shareholders or holders of Warrants.
                                        Shareholders or holders of Warrants
                                        of the Company will continue to hold
                                        their shares or Warrants at the same
                                        aggregate adjusted cost base as
                                        before the Consolidation and
                                        Domestication.
 
                                        Any dividends paid by the Company or
                                        ATSI Merger Corp. after the
                                        Domestication must be included by
                                        shareholders in computing their
                                        income and will not be eligible for
                                        the gross up and dividend tax credit
                                        or other rules applicable to
                                        dividends from Canadian corporations.
 
                                        Shareholders who exercise dissenters'
                                        rights in respect of the
                                        Domestication may be deemed to have
                                        received a dividend and may realize a
                                        capital gain or loss on receipt of
                                        payment for their shares.
 
                                        A shareholder will not realize a
                                        capital gain or loss on the Merger,
                                        unless he or she elects otherwise.
                                        Absent such election, the shareholder
                                        will continue to hold his or her
                                        shares at the same adjusted cost base
                                        as before the Merger.  A holder of
                                        Warrants of ATSI may realize a
                                        capital gain or loss as a result of
                                        the Merger.  See "Canadian and United 
                                        States Income Tax Considerations".
 
United States Federal Income            The Company believes that the
Tax Consequences                        Consolidation will not constitute a
                                        taxable event to the Company and that
                                        the Domestication and Merger will
                                        constitute a tax-free reorganization
                                        for United States federal income tax
                                        purposes and that no gain or loss
                                        will be recognized by United States
                                        shareholders of ATSI as a result of
                                        the Consolidation and on the exchange
                                        of Common Shares for shares of ATSI
                                        Merger Corp. Common Stock in
                                        connection with the Domestication and
                                        Merger.  Thus, provided they satisfy
                                        the necessary filing requirements,
                                        shareholders will not be subject to
                                        United States income tax as the
                                        result of the Domestication and
                                        Merger except to the extent that (i)
                                        they receive cash as a result of
                                        dissenting and (ii) either such
                                        shareholders are U.S. persons or such

                                        received by corporate shareholders
                                        will, subject to applicable
                                        exceptions and restrictions, be
                                        eligible for the 70% dividends
                                        received deduction.  Moreover,
                                        dividends paid to United States
                                        shareholders after the Domestication
                                        and Merger will no longer be subject
                                        to Canadian withholding tax.  ATSI
                                        has never paid cash dividends on its
                                        Common Shares.  There is no current
                                        expectation that dividends will be
                                        paid on the ATSI Merger Corp. Common
                                        Stock for the foreseeable future.

                                        Securities--Dividend Policy."
 
                                        Holders of Warrants of ATSI should not
                                        recognize gain or loss.  However, the
                                        IRS or courts could disagree with
                                        this characterization of the results
                                        to Warrant holders and instead treat
                                        the transaction in connection with
                                        the Warrants as a taxable exchange of
                                        the Warrants.
 
                                        ALL COMPANY SHAREHOLDERS SHOULD READ

                                        each outside director (as defined
                                        therein) will automatically receive a
                                        grant of nonqualified stock options
                                        for 7,500 shares (3,750 shares as

                                        in the future will in addition
                                        receive an initial grant of

                                        The Board of Directors may, however,
                                        terminate the 1996 Option Plan at any
                                        time prior to the end of such period.
                                        Termination of the 1996 Option Plan
                                        will not alter or impair, without the
                                        consent of the optionee, any of the
                                        rights or obligations pursuant to any
                                        then-outstanding option granted under
                                        the 1996 Option Plan.
 
Principal Reasons for Approving the     The purpose of the 1996 Option Plan
1996 Option Plan                        is to promote the interest of the
                                        Company and its shareholders by
                                        providing an effective means to
                                        attract, retain and increase the
                                        commitment of certain individuals and
                                        to provide such individuals with
                                        additional incentive to contribute to
                                        the success of the Company.
 
Tax Consequences                        There exist certain tax consequences
                                        in connection with options granted
                                        under and exercised pursuant to the
                                        1996 Option Plan.  For a general
                                        description of such tax consequences
                                        based on present tax law, which is

                SUMMARY HISTORICAL CONSOLIDATED FINANCIAL DATA

  The summary historical financial data set forth below for the period from
December 17, 1993 through July 31, 1994, the year ended July 31, 1995 and the
six months ended January 31, 1995 and 1996 have been derived from the Company's
historical financial statements appearing elsewhere in this Prospectus.  The
results for the six months ended January 31, 1996 are not necessarily indicative
of the results to be expected for the full year.

  The Company has a limited operating history, has incurred significant losses
from oeprations since its inception and has had working capital deficits in the
past. There is no assurance that the Company will become profitable or will be
able to generate future revenue levels sufficient to support operations or
recover its investment in property and equipment. These matters raise
substantial doubt about the Company's ability to continue as a going concern.
The independent accountant's report on the Company's financial statements for
the year ended July 31, 1995 contains an explanatory paragraph regarding the
Company's ability to continue as a going concern. See Report of Independent
Accountants contained in, and Note 2 to, the Financial Statements for the year
ended July 31, 1995. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations - Liquidity and Capital Resources;" and
"Risk Factors - Risks Relating to the Company - Limited Operating History;
History of Losses; Need for Capital; Report of Independent Accountants." The
summary historical financial data presented below should be read in conjunction
with the Company's historical financial statements included elsewhere in this
Prospectus, the notes thereto and the information set forth under the headings
"Selected Consolidated Financial Data," "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and "Business." The Company's
historical financial statements have been prepared on the accrual basis of
accounting in conformity with U.S. GAAP. The following data is presented in U.S.
dollars.

                                 RISK FACTORS

  The Company's operations and the transactions described herein are subject to
certain significant risks, including the following:

RISKS RELATING TO THE COMPANY

  LIMITED OPERATING HISTORY; HISTORY OF LOSSES; NEED FOR CAPITAL; REPORT OF
INDEPENDENT ACCOUNTANTS. The Company has a limited operating history, has
incurred significant losses from operations since its inception and has had
working capital deficits in the past. In addition, the Company had negative cash
flows from operations during fiscal years 1994 and 1995 and during the six
months ended January 31, 1996. Since its formation, the Company has required
ongoing capital investment. There can be no assurance that the Company will
become profitable or will be able to generate future revenue levels sufficient
to support operations or recover its investment in property and equipment. The
Company anticipates that significant financing will be required from time-to-
time to fund various of the Company's capital commitments, expansion plans and
ongoing operations. These matters raise substantial doubt about the Company's
ability to continue as a going concern. The ability of the Company to continue
as a going concern is dependent upon the ongoing support of its stockholders and
customers and its ability to obtain capital resources. Although the Company is
currently involved in discussions with potential investors and/or strategic
partners, there can be no assurance that additional capital will be available to
the Company from any source or that, if available, it will be on terms
acceptable to the Company. The unavailability of acceptable financing would
materially and adversely impact the Company's ability to implement development
plans for its operations. The independent accountant's report on the Company's
financial statements for the year ended July 31, 1995 contains an explanatory
paragraph regarding the Company's ability to continue as a going concern. See
Report of Independent Accountants contained in, and Note 2 to, the Financial
Statements for the year ended July 31, 1995. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations - Liquidity and
Capital Resources."

  DEVELOPMENT PLANS.  Although the Company believes that its infrastructure
relative to private networks and long distance call services is relatively
complete and, therefore, capable of handling substantial amounts of traffic, the
Company's business development plans, particularly with respect to private
networks and international long distance call services, are currently in the
initial stages.  The Company believes, however, that the markets it serves with
respect to private networks and long distance call services have the potential
to grow significantly in the future.  Accordingly, the Company expects that the
number of and volume utilization within its private networks, and volume of
international long distance calls handled, will be relatively low initially, but
that such volume will increase as the development plans are implemented.
Because of all of the factors described herein affecting the Company's
operations, however, there can be no assurance that such market growth or volume
increase will actually be realized or, if so, when such growth or increase will
occur.

  RELIANCE ON KEY PERSONNEL.  The Company's success depends to a significant
extent on a small number of key technical and managerial personnel, the loss of
any one of which could have a material adverse effect on the Company's
operations.  The Company believes that its future success will also depend in
part upon its ability to attract and retain highly skilled technical and
managerial personnel.  Competition for such personnel is intense.  On May 10,
1994, the Company purchased a $500,000 life insurance policy on Arthur L. Smith,
the Company's President, in his name.  Mr. Smith has named the Company as the
beneficiary of the policy.  There can be no assurance that the Company will be
successful in attracting and retaining the personnel it requires to grow and
operate profitably.  See "Management."

  COMPETITION.  The U.S.-based international communications services market is
dominated by American Telephone and Telegraph Company ("AT&T"), MCI
Communications Corporation ("MCI") and Sprint Communications Company, L.P. 
("Sprint"). The Company competes with Telmex and GeoComm/SERSA, among

                                       13
<PAGE>
 
others, in providing private network management services to and from Mexico.  As
the Company's network expands to serve a broader range of users, ATSI expects to
encounter increasing competition from major domestic and international
communications companies, including the aforementioned carriers, many of which
have significantly greater resources and more extensive domestic and
international satellite and fiber optic communications networks than the
Company.  See "Business--Network Management--Competition" and "Business--Long
Distance Call Services--Competition."

  The long distance call services market is intensely competitive and is
significantly affected by new service introductions and the market activities of
major industry participants.  Competition in the operator services business is
based upon pricing, customer service, network quality and value-added services.
In operator services within the U.S., the Company competes with AT&T, MCI,
Sprint and over 100 other operator services companies across the continental
United States.  Some of the Company's competitors have greater name recognition,
more extensive transmission networks and greater engineering and marketing
capabilities than the Company and have, or have access to, substantially greater
financial and personnel resources than those available to the Company.  The
Company competes in the international long distance call service market with
AT&T, Sprint, MCI, CNSI and others, many of which also have considerably greater
financial and other resources than the Company.  The ability of the Company to
compete effectively in the telecommunications industry will depend upon its
continued ability to maintain high quality, market driven services at prices
generally equal to or below those charged by its competitors.  There can be no
assurance that the Company will be able to compete successfully with existing or
future competitors.

  REGULATIONS.

  The Company's domestic long distance call services activities are subject to
the regulations of the U.S. Federal Communications Commission ("FCC") and the
public utility commissions of the various states in which the Company operates.
These regulatory agencies are governed by respective federal or state
legislation and, therefore, any change or modification to such regulation or
legislation can result in positive or negative effects upon the Company.
Decisions by the state or federal legislative or regulatory bodies with respect
to the permissible business activities or pricing practices of the Company's
competitors, such as AT&T and the seven Regional Bell Operating Companies
("RBOCs"), may also have an adverse impact on the Company's operations.
Moreover, any significant change in regulations by federal or state governmental
agencies could significantly increase the Company's costs or otherwise have an
adverse effect on the Company's activities and on its expansion efforts.

     Federal.  The Company is subject to regulation by the FCC, and the
regulations promulgated by the FCC are subject to change in the future.  There
can be no assurance that future judicial and legislative changes will not have a
material adverse effect on the Company, that regulators or third parties will
not raise material issues with regard to the Company's compliance with
applicable regulations, or that regulatory activities will not have a material
adverse effect on the Company.

  The Company has been granted requisite authorization from the FCC to operate
its San Antonio, Texas-based satellite teleport (the "Teleport"), which
transmits and receives signals from the Solidaridad international satellite
system.  FCC licensing decisions or changes in U.S. government policies
increasing or decreasing access to non-Intelsat satellites or other network
components could adversely affect the Company, particularly if such decisions or
changes were to result in a reallocation of access rights among the Company and
its competitors.  There can be no assurance that the Company will receive all
authorizations or licenses necessary for new communications services or that
delays in the licensing process will not adversely affect the Company's
business.  In addition, there can be no assurance that such authorizations will
not be rescinded, although such action is unlikely.

  The Company's transmitting equipment must comply with FCC technical standards,
which are subject to change and can result in the premature obsolescence of
equipment.  The Company monitors its compliance

                                       14
<PAGE>
 
with federal, state, and local regulations governing the discharge and disposal
of hazardous and environmentally sensitive materials including, but not limited
to, the emission of electromagnetic radiation.  Although the Company believes it
is in compliance with such regulations, there can be no assurance that any such
discharge, disposal or emission will not expose the Company to claims or actions
that could have a material adverse effect on the Company's financial results.

  To originate and terminate calls in connection with providing their services,
long distance carriers such as the Company must purchase "access" from the local
exchange carriers ("LECs").  Access charges represent a portion of the Company's
cost of services and, generally, such access charges are regulated by the FCC.
The FCC has informally announced that it intends, in the near future, to
undertake a comprehensive review of its regulation of LEC access charges to
better account for increasing levels of local competition.  Implementation of a
new access charge structure could place many interexchange carriers, including
the Company, at a significant cost disadvantage, either in absolute terms or in
relative terms, to the larger competitors.  Agreements with foreign carriers are
also subject to FCC regulations, foreign laws, and the terms of international
treaties.  If these regulations, laws or treaties are construed in such fashion
to require changes to the Company's current agreements, such changes could have
a material adverse effect on the Company.  Additionally, if a concept proposed
by the FCC whereby a caller could make a long distance call from any publicly
available telephone and have the call automatically routed over the long
distance telephone network of the caller's choice, called Billed Party
Preference ("BPP"), is implemented, such implementation could have a material
adverse effect on the Company.  See "Business-Regulation."

     State.  The Company is subject to state regulation that varies by
jurisdiction and is subject to change.  Generally, the Company must obtain and
maintain certificates of public convenience and necessity from many state
regulatory authorities where it offers intrastate long distance services.  In
most cases, it must also file tariffs for its intrastate offerings.  To date,
the Company has experienced no unusual difficulties or delays in obtaining
necessary state authorizations.  However, there can be no assurance that the
Company will not experience difficulties or delays in the future or that any
such difficulties or delays will not adversely affect the Company's business.
Additionally, many states are relaxing the regulatory restrictions currently
imposed on the LECs.  There can also be no assurance that future judicial and
legislative changes will not have a material adverse effect on the Company.  See
"Business-Regulation."

     Foreign.  The services currently provided by the Company are not directly
subject to laws of other countries, but the foreign carriers with which the
Company conducts business are subject to those laws.  Certain countries are
considering opening their markets to competition.  In the process, they may
impose regulatory requirements that could have a material adverse effect on the
Company.  See "Business-Regulation."

  POSSIBLE UNAVAILABILITY OF LEASED TRANSMISSION FACILITIES.  The Company
believes it has ample access to leased transmission facilities at cost-effective
rates and expects to continue to have such access in the foreseeable future
because technological improvements in recent years have increased the capacity
of existing digital fiber optic and satellite-based transmission facilities.
There can be no assurance, however, that such leased facilities will be
available to the Company at cost-effective rates in the future.

  The Company currently owns only a portion of the transmission facilities
needed to complete long distance telephone calls.  Therefore, the Company's long
distance call services business is dependent upon contractual arrangements, both
long and short-term, with carriers for the transmission of calls.  While the
Company believes that it has ample access to transmission facilities at
competitive rates and expects to continue to have such access in the foreseeable
future, this ongoing availability cannot be assured.

  Since its inception, the Company has provided long distance services for calls
originating from Mexico without the benefit of laws in Mexico requiring
Telefonos de Mexico ("Telmex") to resell its available network capacity to other
carriers at a wholesale price.  Although the Company has contracted with major

                                       15
<PAGE>
 
U.S. carriers to originate calls from Mexico, Telmex has on occasion refused to
provide those services to those carriers.  Telmex has also increased per minute
charges to those carriers, and, consequently, those carriers have increased per
minute charges to the Company, the result of which has been a rapidly changing,
and often increasing cost structure relative to the Company's international long
distance services.  The Company, through ATSI-Mexico, has applied or intends to
apply to the SCT for several licenses, which, if obtained, the Company believes
will enable it to expand significantly its call services business in Mexico by,
among other things, permitting the Company to purchase Telmex network capacity
at a more stable wholesale price.  There can be no assurance, however, that such
licenses will be obtained, and, if obtained, that Telmex will not again refuse
to provide service or increase charges, the result of either of which could have
a materially adverse effect on the Company's business.  See "Business--ATSI-
Mexico."

  RISK OF DAMAGE, LOSS OR MALFUNCTION OF SATELLITE.  The loss, damage or
destruction of any of the Solidaridad satellites as a result of military actions
or acts of war, anti-satellite devices, electrostatic storm or collision with
space debris, or a temporary or permanent malfunction of any of the Solidaridad
satellites, would have a material adverse short-term effect on the Company;
however, the Company believes that suitable arrangements could be obtained with
other satellite operators to provide satellite transmission capacity, although
the interruption of service, if any, could have a detrimental effect on the
Company's business.

  DEPENDENCE ON INDEPENDENT MARKETING REPRESENTATIVES.  The Company's business
depends on its major independent marketing representatives continuing to provide
the Company with customers requiring the provision of long distance call
services, such as hotels, motels and pay telephone owners.  The loss of one or
more such independent marketing representative, or the loss of active
solicitation of customers on behalf of the Company by one or more such
independent marketing representative, would have a materially adverse effect on
the Company's business, the effect of which would depend primarily on the length
of time necessary for the Company to find suitable alternative independent
marketing representatives, which the Company believes, in most instances, would
be relatively short.  There can be no assurance, however, that alternative
independent marketing representatives can be located in a timely manner.

  TECHNOLOGICAL CHANGE AND NEW SERVICES.  The telecommunications industry has
been characterized by steady technological change, frequent new service
introductions and evolving industry standards.  The Company believes that its
future success will depend on its ability to anticipate such changes and to
offer on a timely basis market responsive services that meet these evolving
industry standards.  The Company has constructed its San Antonio, Texas-based
Network Control Center/Teleport using state-of-the-art digital satellite
communications equipment, and built the network operating system modularly to
enable it to expand telecommunications capacity quickly, on an as-needed basis.
However, there can be no assurance that the Company will have sufficient
resources to make the investments necessary to acquire new technology or to
introduce new services that would satisfy an expanded range of customer needs.

  SERVICE INTERRUPTIONS; EQUIPMENT FAILURES.  The Company's business requires
that transmission and switching facilities and other equipment be operational 24
hours per day, 365 days per year.  Long distance telephone companies such as the
Company on occasion may experience temporary service interruptions or equipment
failures, in some cases resulting from causes beyond their control.  Any such
event experienced by the Company would impair the Company's ability to service
its customers and could have a material adverse effect on the Company's
business.  The Company's Control Center is, however, protected through an
uninterruptable power supply system which, upon commercial power failure,
utilizes battery back-up until an on-site natural gas generator is automatically
triggered to supply AC power.

  INCREASED EXPENDITURES FOR ANTICIPATED EXPANSION.  To facilitate and support
the growth anticipated in its business, the Company anticipates that it will
expand operations, and thus increase its investments in personnel and
facilities.  Due to the anticipated increase in the Company's overhead and
operating expenses resulting from any such expansion, the Company's operating
results may be adversely affected if its revenues do not increase to the extent
expected.

                                       16

  SEASONAL VARIATIONS IN REVENUES.  Seasonal variation in call volume is
expected by the Company from hospitality and payphone subscribers, reflecting
the higher occupancy rates during the winter vacation months in Mexico (when
U.S. volume is at its lowest) and lower rates during summer months in Mexico
(when U.S. volume is at its peak).

  CUSTOMER ATTRITION.  The Company believes that a certain level of customer
attrition is common in the long distance call services industry.  Although the
Company has not experienced significant attrition in its various businesses, the
Company's historical levels of customer attrition may not be indicative of
future attrition levels, and there can be no assurance that any steps taken by
the Company to counter increased customer attrition would accomplish the
Company's objectives.  In addition, recent acquisitions and consolidations in
the telecommunications industry have resulted in, and may in the future result
in, the loss of customers by the Company because of the acquisition of these
customers by large companies that have existing contractual relationships with
the Company's competitors.

RISKS OF LATIN AMERICAN OPERATIONS

  GENERAL.  The majority of the Company's international operations are currently
being conducted in Mexico.  As a result, such operations are subject to
political, economic and other uncertainties, including, among others, risk of
war, revolution, expropriation, renegotiation or modification of existing
contracts, communications regulations, standards and tariffs, taxation policies,
licensing requirements, as well as international monetary fluctuations which may
make payment in U.S. dollars more expensive for foreign customers and other
uncertainties and trade barriers.  Consequently, the Company may encounter
unforeseen difficulties in conducting operations in Mexico, including but not
limited to the risks set forth below.  The Company also intends to conduct
operations in other countries within Latin America and all of these factors
could also apply to a greater or lesser extent to operations conducted by the
Company in such other countries.

  LEGAL FRAMEWORK GOVERNING COMMUNICATIONS OPERATIONS.  On June 7, 1995, the
Secretaria de Communicaciones y Transportes ("SCT"), the agency which is
responsible for governing telecommunications services in Mexico, promulgated a
law prescribing the method by which companies could apply for concessions and
licenses to establish and operate telecommunications services businesses within
Mexico.  This was, effectively, the first step in the deregulation of the
telephone industry within Mexico.  It also formalized the methods by which
companies such as ATSI may compete against Telmex, the privately owned
telecommunications monopoly in Mexico.  The Company, through ATSI-Mexico, has
applied or intends to apply for several licenses to provide various
telecommunications services within Mexico.  The Company anticipates receiving
various of these licenses during calendar year 1996, and believes that the
receipt of such licenses will enable the Company to expand significantly its
call services business in Mexico; however, there can be no assurance that such
licenses will be obtained, and, if obtained, that such licenses will enable the
Company to expand operations or increase revenues in Mexico.  In the event that
there is a significant delay in obtaining the licenses, or in the event that
future regulations promulgated by the SCT are unfavorable to the Company's
business, the Company could be materially adversely affected.

  CHANGES IN LAWS.  Changes in laws applicable to the Company's business,
including income tax laws, communications laws, foreign investment laws and
currency exchange laws could materially and adversely affect the results of the
Company's operations.  Recently, certain changes in some laws have been
implemented which the Company believes will enable it to expand its business,
particularly in Mexico.  There can be no assurance, however, that subsequent
changes in such laws will not have a material adverse effect on the Company or
the material terms of contracts to which it is a party.

  POLITICAL INSTABILITY.  The political and economic instability in Mexico and
other countries in Latin America could result in the adoption of new policies,
lead to trade disputes or impede the access of the Company to sources of
financing for its operations in the future, any of which could materially and
adversely affect the Company.  The Company has no insurance against political
instability.

                                       17
<PAGE>
 
  UNCERTAIN OPERATING CONDITIONS.  The Company believes that, through its own
resources and those of potential joint venture partners and available
independent contractors, it will have adequate access to the equipment,
personnel, communications service organizations and technical expertise
necessary to conduct future operations in Mexico and other countries in Latin
America.  However, if any of the Company's understandings or assumptions change
or prove inaccurate, the Company's operations could be materially adversely
affected.

RISKS RELATING TO OWNERSHIP OF COMPANY SECURITIES AND THIS OFFERING.

  ANTI-TAKEOVER PROTECTIONS.  ATSI Merger Corp.'s Certificate of Incorporation
and Bylaws contain certain provisions, including a classified board of
directors, prohibitions on stockholder actions by written consent in certain
circumstances, "blank check" preferred stock, advance notice requirements for
director nominations and actions to be taken at annual meetings and the
protections afforded by Section 203 of the DGCL and certain super-majority
voting requirements.  Such provisions could impede any merger, consolidation,
takeover or other business combination involving the Company or discourage a
potential acquiror from making a tender offer or otherwise attempting to obtain
control of the Company.  See "Description of ATSI Merger Corp. Securities--
Provisions Having Anti-Takeover Effects" and "Management--Executive Officers and
Directors."

  ISSUANCE OF ADDITIONAL SHARES.  The Company currently has outstanding warrants
to purchase approximately 5.19 million Common Shares at a weighted average
purchase price of $0.92 per share.  See "Description of ATSI Merger Corp.
Securities."  In view of the Company's continued cash needs to meet it
commitments, the Company is currently involved in discussions with potential
investors and/or strategic partners.  Transactions with such persons could
involve the issuance of shares of additional capital stock.  However, ATSI has
no definitive agreement with any such potential investor or strategic partner
and there can be no assurances that such an agreement will be concluded.  Sales
of a substantial amount of Common Shares or a perception that such sales could
occur, may adversely affect the prevailing market price of the Common Shares.

  NO DIVIDENDS.  The Company intends to retain future earnings for use in its
business and does not anticipate paying any dividends on any of its capital
stock in the near future.  See "Dividend Policy."

  INABILITY TO EXERCISE, CONVERT OR EXCHANGE THE SECURITIES UNDER FEDERAL AND
STATE SECURITIES LAWS.  No warrants, the underlying shares of which are
registered hereunder, will be exercisable unless at the time of exercise the
Company has a current prospectus effective with the Commission covering the
Common Shares, or shares of ATSI Merger Corp. Common Stock in the event the
Merger occurs, issuable upon exercise of such warrants and such shares have been
registered or qualified or deemed to be exempt under the securities laws of the
state of residence of the holder.  The Company will endeavor to have the Common
Shares or shares of Common Stock, as the case may be, so registered or qualified
on or before the exercise or exchange date (as applicable) and to maintain a
current prospectus relating thereto, although there can be no assurance that the
Company will be able to do so (or determine that doing so is cost effective).
If a registration statement covering such shares is not kept effective for any
reason, or if the shares issuable upon the exercise of the warrants are not
registered in the state in which a holder resides, the warrants will not be
exercisable and may be deprived of substantial or all of their value.

  ABSENCE OF EFFICIENT PUBLIC MARKET; POSSIBLE VOLATILITY OF STOCK PRICE.  The
Company's Common Shares are currently traded on the Canadian Dealing Network.
Such exchange may not provide for an active public market for the Company's
securities and there can be no assurance that an active trading market for the
Common Shares, or shares of ATSI Merger Corp. Common Stock in the event the
Merger occurs, will develop or, if developed, that it will be sustained.  The
market price of the Common Shares or shares of Common Stock, as the case may be,
could be subject to significant fluctuations in response to variations in
results of operations and other factors.  Developments affecting the
telecommunications industry generally, including national and international
economic conditions and government regulations, could also have a

                                       18
<PAGE>
 
significant impact on the market price of the Common Shares or shares of Common
Stock, as the case may be.  In addition, the equity markets in recent years have
experienced price and volume fluctuations that often have been unrelated or
disproportionate to the operating performance of companies; the price of the
Common Shares or shares of Common Stock, as the case may be, could be affected
by such fluctuations.

  MARKET LISTING.  ATSI Merger Corp., or ATSI in the event the Merger is not
approved by the shareholders or otherwise does not occur, may in the future
apply for listing on the Nasdaq National Market, Nasdaq SmallCap Market or
another securities market or exchange, which listing may require the
satisfaction of certain conditions, including without limitation minimum per
share price requirements.  There can be no assurance, however, that ATSI or ATSI
Merger Corp., as the case may be, will at the time of a proposed listing be able
to satisfy such listing requirements or, if so, that the applicable securities
market or exchange would in any event accept the Common Shares or ATSI Merger
Corp. Common Stock for listing.  The ATSI Merger Corp. Common Stock or the
Common Shares, as the case may be, would, however, remain listed on the Canadian
Dealing Network.

  TAX CONSEQUENCES OF THE DOMESTICATION AND MERGER ON HOLDERS OF WARRANTS
Although the matter is not free from doubt, for United States federal income tax
purposes, the Domestication and Merger should not result in the recognition of
gain or loss under Section 1001 of the Internal Revenue Code of 1986, as amended
(the "Code") to the holders of Warrants in ATSI. The Internal Revenue Service or
the courts could disagree with this characterization of the results to Warrant
holders and instead treat the transaction in connection with the Warrants as a
taxable exchange. In such event, each U.S. Holder (as defined under "Canadian
and United States Income Tax Considerations--United States Tax Consequences") of
Warrants will recognize gain or loss on the exchange equal to the difference
between the fair market value of its Warrants after the Merger and the adjusted
tax basis of its Warrants of ATSI (which such gain or loss will be capital gain
or loss if the Warrants are capital assets that have been held for more than one
year). Each holder of Warrants is urged to consult its own tax advisor regarding
the tax consequences of the Domestication and Merger on its particular
circumstances.

  See "Canadian and United States Income Tax Considerations" for a further
description of the tax consequences of the Consolidation, Domestication and the
Merger.

                           GENERAL PROXY INFORMATION

SOLICITATION OF PROXIES

  Proxies are being solicited by and on behalf of the management of ATSI.  All
expenses in connection with the solicitation of proxies will be borne by ATSI,
including charges made by brokers and other persons holding stock in their names
or in the names of nominees for reasonable expenses incurred in sending proxy
material to beneficial owners and obtaining their proxies.  Solicitation will be
by mail or by regular employees of ATSI.  No arrangement has been entered into
with any other party for the solicitation of proxies for a fee.

APPOINTMENT AND REVOCATION OF PROXIES

  The persons named in the enclosed forms of proxy (the "Proxy") are members of
management of ATSI.  Two forms of Proxy are being solicited through this
Prospectus:  the first form seeks to appoint the persons named therein to
represent the holder at the Meeting to vote on special resolutions to authorize
the First Consolidation, Second Consolidation and the Domestication and the
adoption of the 1996 Option Plan and certain related matters, and to transact
such other business as may properly come before the Meeting or any
adjournment(s) thereof.  The second form seeks to appoint the persons named
therein to act as proxy and attorney-in-fact to execute the Consent following
the completion of the Domestication to authorize the Merger.

  THE HOLDER OF OR A PERSON DEEMED TO BE THE HOLDER OF COMMON SHARES HAS THE
RIGHT TO APPOINT A PERSON TO REPRESENT HIM OR HER AT THE MEETING OR FOR THE
EXECUTION OF THE CONSENT OTHER THAN THE PERSONS DESIGNATED IN THE RESPECTIVE
FORM OF PROXY.  SUCH RIGHT MAY BE EXERCISED BY STRIKING OUT THE NAMES OF THE
PERSONS NAMED IN THAT FORM OF PROXY AND INSERTING THE NAME OF THE SHAREHOLDER'S
NOMINEE IN THE SPACE PROVIDED, OR BY COMPLETING ANOTHER PROPER FORM OF PROXY.  A
PROXY FOR THE MEETING OR THE EXECUTION OF THE CONSENT MUST BE RECEIVED (I) IN
THE CASE OF THE MEETING, BY THE SECRETARY OF ATSI OR THE CHAIRMAN OF THE
MEETING, AT ANY TIME PRIOR TO OR DURING THE MEETING OR ANY ADJOURNMENT THEREOF
OR (II) IN THE CASE OF THE CONSENT IN LIEU OF MEETING, BY THE SECRETARY PRIOR TO
EFFECTIVENESS OF THE CONSENT.

  A shareholder forwarding the Proxy may indicate the manner in which the
appointee is to vote with respect to any specific item by checking the
appropriate space.  If the shareholder giving the Proxy wishes to confer a
discretionary authority with respect to any item of business then the space
opposite the item is to be left blank.  The shares represented by the Proxy
submitted by a shareholder will be voted in accordance with the directions, if
any, given in the Proxy.

  A shareholder who has given a Proxy may revoke it at any time in so far as it
has not been exercised.  A Proxy may be revoked, as to any matter on which a
vote shall not already have been cast pursuant to the authority conferred by
such Proxy, by depositing an instrument in writing executed by the shareholder
or by his attorney authorized in writing or, if the shareholder is a body
corporate, by an officer or attorney thereof duly authorized, at the registered
office of ATSI at any time up to and including the last business day preceding
the day of the Meeting or any adjournment(s) thereof at which the Proxy is to be
used or with the Chairman of such Meeting on the date of the Meeting or any
adjournment(s) thereof.  A Proxy may also be revoked in any manner permitted by
law.

VOTING OF SHARES REPRESENTED BY MANAGEMENT PROXIES

  GENERAL

  As at the date hereof, 19,965,312 Common Shares were issued and outstanding.
Each such Common Share entitles the holder thereof to one vote on all matters to
be acted upon at the Meeting.  All holders of Common Shares of record as of the
time of the Meeting or any adjournment(s) thereof are entitled either to

                                       20
<PAGE>
 
attend and vote thereat in person the Common Shares held by them or, provided an
executed Proxy shall have been delivered to ATSI within the time specified in
the attached Notice of Meeting, to attend and vote thereat by Proxy the Common
Shares held by them.  See "Description of ATSI Merger Corp. Securities."

  MEETING

  A shareholder forwarding the Proxy may indicate the manner in which the
appointee is to vote with respect to any specific item by checking the
appropriate space.  The persons named in the form of Proxy will vote the shares
in respect of which they are appointed in accordance with the direction of the
shareholders appointing them.  However, in the absence of such direction, THE
NOMINEES INTEND TO VOTE THE SHARES REPRESENTED BY THE PROXY:

  1. FOR the special resolution authorizing and approving the First
     Consolidation (See "The Consolidation").

  2. FOR the special resolution authorizing and approving the Second
     Consolidation (See "The Consolidation").

  3. FOR the special resolution authorizing the Domestication (See
     "Domestication and Merger -- The  Domestication").

  4. FOR the resolution authorizing the adoption of the 1996 Option Plan (See
     "The 1996 Option Plan").

  The enclosed form of Proxy, when properly signed, confers discretionary
authority upon the persons named therein with respect to amendments or
variations to matters identified in the Notice of Meeting and with respect to
other matters which may properly come before the Meeting or any adjournment(s)
thereof.  At the time of the printing of this Prospectus, management knows of no
such amendments, variations or other matters to come before the Meeting other
than the matters referred to in the Notice of Meeting.  However, if any other
matters which are not now known to management should properly come before the
Meeting or any adjournment(s) thereof, the Proxy will be voted on such matters
in accordance with the best judgment of the proxies named therein.

  CONSENT

  A Proxy from a shareholder for the Consent in lieu of meeting received by
management will be exercised in the manner specified in the Proxy by such
shareholder, unless authority to exercise the Proxy is withheld or the Proxy is
left blank.  If the Proxy is left blank, the proxies named in the Proxy for the
Consent in lieu of meeting will exercise the authority with respect to the
shares represented by such Proxy by executing a Consent FOR the Merger.

  BECAUSE THE CONSENT IS EFFECTIVE ONLY IF EXECUTED ON BEHALF OF A MAJORITY OF
THE TOTAL NUMBER OF COMMON SHARES OUTSTANDING, THE FAILURE TO CONVEY A PROXY TO
EXPRESS CONSENT OR THE WITHHOLDING OF AUTHORITY TO EXPRESS CONSENT HAS THE SAME
EFFECT AS A VOTE "AGAINST" THE MERGER.

VOTING SHARES AND RECORD DATE

  MEETING

  The Board of Directors has fixed __________, 1996 as the record date, being
the date for the determination of the registered holders of securities entitled
to receive Notice of the Meeting pursuant to National Policy No. 41, as amended,
issued by the securities commissions and comparable regulatory bodies of the
Provinces of Canada.  Any non-registered shareholder that has requested or
requests to be registered

                                       21
<PAGE>
 
as a shareholder in the time allotted pursuant to such Policy will be listed on
the list of shareholders referred to below.

  In accordance with the provisions of the OBCA, ATSI will prepare a list of
holders of Common Shares at the close of business on a date not later than 10
days after the record date.  Each holder of Common Shares named in the list will
be entitled to vote the Common Shares shown opposite his name except to the
extent that:  (i) the shareholder has transferred any of his shares after the
record date and (ii) the transferee of those shares produces properly endorsed
share certificates or otherwise establishes that he owns such shares and demands
not later than 48 hours before the Meeting that his name be included in the list
before the Meeting, in which case the transferee is entitled to vote his shares
at the Meeting.

  CONSENT

  After the Domestication becomes effective, pursuant to the DGCL, the Consent
will be executed on behalf of those shareholders who (i) have delivered proxies
marked in favor of or not against the Merger and (ii) are shareholders of the
Company on the record date with respect to the Merger.  The record date with
respect to shareholders entitled to be included in the Consent to the Merger
will be deemed to be the date the Consent is presented to the Company.  This
date will be as soon as practicable after the Domestication becomes effective.
SINCE A SHAREHOLDER MUST HOLD THE COMMON SHARES TO BE VOTED IN HIS NAME UNDER
THE CONSENT ON THE DATE THE CONSENT IS EXECUTED, NO PROXY WITH RESPECT TO THE
CONSENT WILL BE EFFECTIVE IF THE HOLDER EXECUTING THE PROXY IS NO LONGER A
HOLDER OF RECORD AT THE TIME THE CONSENT IS EXECUTED.  ACCORDINGLY, HOLDERS OF
COMMON SHARES WHO WISH TO HAVE THEIR SHARES REPRESENTED IN THE EXECUTION OF THE
CONSENT TO THE MERGER SHOULD REFRAIN FROM SELLING OR TRANSFERRING ANY COMMON
SHARES UNTIL AFTER THE MERGER BECOMES EFFECTIVE.


                               THE CONSOLIDATION

  The Company is asking its shareholders to pass (i) a special resolution
authorizing the filing of Articles of Amendment consolidating the issued and
outstanding Common Shares on the basis of one Post-Consolidation Common Share
for every two Pre-Consolidation Common Shares of the Company (the "First
Consolidation") and (ii) a special resolution authorizing the filing in the
future of one additional charter amendment (without further action of
shareholders) further consolidating, on a one-for-two basis, the issued and
outstanding Common Shares, or shares of ATSI Merger Corp. Common Stock in the
event the Merger occurs, if the Board of Directors in its sole discretion deems
necessary to satisfy the minimum per share price requirements for listing on the
Nasdaq National Market, Nasdaq SmallCap Market or another securities market or
exchange (the "Second Consolidation" and, together with the First Consolidation,
the "Consolidation").

  The Board of Directors believes that the Consolidation is in the best
interests of the shareholders because over the long term the Company will have
greater flexibility with respect to future equity financings which will be
necessary to develop the Company's business.  Furthermore, the Company, or ATSI
Merger Corp. in the event the Merger occurs, may in the future apply for listing
on the Nasdaq National Market, Nasdaq SmallCap Market or another securities
market or exchange, which listing may require the satisfaction of certain
conditions, including without limitation minimum per share price requirements.

  It is currently anticipated that the Articles of Amendment effecting the First
Consolidation will be filed regardless of whether the Domestication and Merger
are effected.  If the First Consolidation is effected without the Domestication
or Merger being completed, shareholders will be required to surrender their
certificates representing Pre-Consolidation Common Shares in exchange for
certificates representing Post-Consolidation Common Shares.  Appropriate
transmittal forms will be sent to shareholders for this purpose.  Prior to a
share certificate being surrendered, such share certificate will represent whole
shares of the

                                       22
<PAGE>
 
Company on a post-consolidated basis, (an amount equal to one-half of the amount
represented by such share certificate).

  The special resolutions approving the Consolidation will provide that any
person who, on the date that either charter amendment is filed with the Ministry
of Consumer and Commercial Relations or Secretary of State of Delaware, as the
case may be, to give effect to either such resolution, is the registered holder
of a number of Common Shares not divisible by two shall not be entitled to
receive any fractional interest in a Common Share following such consolidation.
All fractions of Post-Consolidation Common Shares will be rounded up to the next
highest whole number.

  The special resolutions will not be effective unless passed at the Meeting by
at least two-thirds of the votes cast.  Notwithstanding such approval, the Board
of Directors may determine not to proceed with the filing of either charter
amendment effecting the Consolidation.

  Exhibits A-1 and A-2 to this Prospectus contain the text of the special
resolutions with respect to the Consolidation to be submitted to the
Shareholders at the Meeting.


                           DOMESTICATION AND MERGER

THE DOMESTICATION

  ATSI is proposing to continue its existence through a "domestication" under
Section 388 of the DGCL.  The continued, or domesticated, corporation will
become subject to the DGCL on the date of its domestication, but will be deemed
to have commenced its existence in Delaware on the date it originally commenced
existence in Ontario.  Under the DGCL, a corporation becomes domesticated in
Delaware by filing a certificate of domestication and a certificate of
incorporation for the corporation being domesticated.  A copy of the proposed
form of the Certificate of Domestication of ATSI that will be filed in Delaware
is attached as Exhibit D.  The Certificate of Incorporation of ATSI that will
be filed in Delaware is the same as the Certificate of Incorporation of ATSI
Merger Corp. (except for the name of the corporation), a copy of which is
attached as Exhibit H.  The Domestication will be effective upon the filing of
such certificates and thereafter ATSI will be subject to such Certificate of
Incorporation.  ATSI will be discontinued in Ontario as of the date a
certificate of discontinuance is issued by the OBCA Director.  Upon the
Domestication, the Board of Directors of ATSI will adopt bylaws which are the
same as the Bylaws of ATSI Merger Corp. (except for the name of the
corporation), a copy of which is attached as Exhibit I.

  The Domestication will not interrupt the existence of ATSI.  Each Common Share
will remain issued and outstanding as a Common Share of ATSI after its corporate
existence is continued from Ontario under the OBCA and domesticated in Delaware
pursuant to the DGCL.  For a summary of certain of the rights of shareholders of
the Company before and after the Domestication, see "Effects of Domestication on
Shareholder Rights."

THE MERGER

  The Merger is proposed to be accomplished as a "short-form" merger of ATSI,
then a Delaware corporation, into its wholly-owned subsidiary, ATSI Merger
Corp., pursuant to Section 253 of the DGCL.  The Certificate of Incorporation
and Bylaws of ATSI Merger Corp. (the "ATSI Merger Corp. Certificate" and "ATSI
Merger Corp. Bylaws," respectively) attached as Exhibits H and I, respectively,
will remain the Certificate of Incorporation and Bylaws of the surviving
corporation in connection with the Merger. A copy of each of the proposed
Certificate of Ownership and Merger relating to the Merger, the ATSI Merger
Corp. Certificate and the ATSI Merger Corp. Bylaws is attached as Exhibit G, H
and I, respectively.

                                       23
<PAGE>
 
  In the Merger, each Common Share issued and outstanding immediately prior to
the Merger will be converted into one share of ATSI Merger Corp. Common Stock.
See "-- Mechanics of Merger."  If the Merger fails to occur, ATSI will continue
its operations as a Delaware corporation and will be governed by the Certificate
of Incorporation of ATSI that will be filed in Delaware and the Bylaws that will
be adopted by the Board of Directors in connection with the Domestication, the
provisions of which are the same as the provisions of the Certificate of
Incorporation and Bylaws of ATSI Merger Corp., copies of which are attached as
Exhibits H and I, respectively.

  Additionally, if approved by the shareholders of ATSI pursuant to the Consent,
immediately following the Merger the name of the surviving company will change
to American Telesource International, Inc. or such other name as may be
authorized by the Board of Directors of ATSI.

  In the Merger, holders of Common Shares will receive one share of ATSI Merger
Corp. Common Stock for every Post-Consolidation Common Share held by such
holder.  Following the Merger, holders of Common Shares will continue to hold
the same percentage interest in ATSI Merger Corp. that they held in ATSI
immediately prior to the Merger.  In addition, in connection with the Merger,
the ATSI Warrants outstanding immediately prior to the Merger will become
obligations of ATSI Merger Corp.

OFFICERS AND DIRECTORS

  The ATSI Board currently consists of three members, Arthur L. Smith, Murray R.
Nye and John R. Moses.  Upon Domestication, the ATSI Board will be increased to
five members and will be divided into three classes, one class of which is to be
elected each year to hold office for a three-year term and until successors are
elected and qualified, as provided by the terms of the Certificate of
Incorporation to be filed pursuant to the Company's Domestication into Delaware.
It is anticipated that immediately following the Domestication, John R. Moses
will resign as a director of ATSI and Arthur L. Smith and Murray R. Nye,
representing a majority of the directors then in office, will elect, in order to
fill such vacancies and newly created directorships on the Board of ATSI, then a
Delaware corporation, Terry Colbert and Tomas Revesz to serve as the Class B
directors and Arthur L. Smith and Murray R. Nye to serve as the Class C
directors.  Messrs. Smith and Nye also intend to appoint a fifth director
immediately following the Domestication to serve as the Class A director, and,
along with Mr. Moses, are currently in the process of interviewing qualified
candidates.  Additionally, immediately following the Domestication, the officers
of ATSI will be as follows:  Arthur L. Smith - President and Chief Executive
Officer; H. Douglas Saathoff - Secretary, Treasurer and Chief Financial Officer;
Craig K. Clement - Vice President; and Everett Waller - Vice President.  All
such individuals who are expected to be the directors and officers of ATSI
immediately prior to the Merger currently are or will be, and immediately after
the Merger will be, the directors and officers of ATSI Merger Corp.  See
"Management--Executive Officers and Directors" for more information concerning
such individuals.

EXCHANGE OF SHARE CERTIFICATES

  As soon as practicable on or after the Merger, ATSI shareholders of record
immediately prior to the Merger will be sent detailed instructions concerning
the procedures to be followed for submission of certificates representing Common
Shares to an exchange agent appointed by ATSI (the "Exchange Agent"), together
with a form of transmittal letter to be sent to the Exchange Agent at the time
such certificates are submitted.

  After the Merger, the Exchange Agent will deliver to any holder who has
previously submitted a duly completed and executed transmittal letter and a
certificate representing Common Shares, a certificate issued by ATSI Merger
Corp. representing the appropriate number of shares of ATSI Merger Corp. Common
Stock into which such Common Shares were converted.

                                       24
<PAGE>
 
  After the Merger but before a certificate representing Common Shares is
surrendered, certificates representing Common Shares will represent the number
of shares of ATSI Merger Corp. Common Stock into which such Common Shares were
converted pursuant to the terms of the Merger.  The transfer agent for the
Company will be instructed to forward to the Exchange Agent any certificates for
shares of capital stock of ATSI otherwise delivered by the shareholder.  The
Exchange Agent will deliver certificates representing the appropriate amount and
type of ATSI Merger Corp. capital stock in accordance with the stockholder's
instructions for transfer or exchange.

CONDITIONS TO DOMESTICATION AND MERGER; SHAREHOLDER APPROVALS

  DOMESTICATION

  The Domestication is subject to, among other things, (i) approval by the ATSI
shareholders of a special resolution authorizing the Domestication (a copy of
which is attached as Exhibit B) by the affirmative vote of at least two-thirds
of the Common Shares voting in person or by proxy at the Meeting or any
adjournment(s) thereof and (ii) authorization of the OBCA Director (ATSI intends
to apply to the OBCA Director to authorize the Domestication sufficiently in
advance of the Domestication in order to obtain such authorization as soon as
possible following approval of the Domestication by the ATSI shareholders).

  MERGER

  The consummation of the Merger is subject to the following conditions:  (i)
the effectiveness of the Domestication; (ii) the adoption of a resolution
approving the Merger by the Board of Directors of ATSI after the Domestication;
and (iii) the approval of the Merger by the Consent executed on behalf of
holders of record of a majority of the outstanding Common Shares after the
Domestication.

  The shareholders of ATSI are being requested to approve the Merger by written
consent, instead of at a special meeting, because the notice and voting
requirements under the DGCL could not be satisfied on a timely basis if a
meeting of the shareholders of ATSI, once domesticated under the DGCL, were held
immediately following the Domestication.  For the Consent to be effective under
the DGCL, it must be expressed, in person or by proxy, by the holders of record
of a majority of the outstanding Common Shares, once ATSI is domesticated under
the DGCL.  Under the DGCL, notice of the Merger must be sent to the non-
consenting shareholders of ATSI promptly following the effectiveness of the
Merger.

  Notwithstanding the requisite shareholder approvals of the Domestication and
Merger, the Board of Directors of ATSI has reserved the right to terminate or
abandon the Domestication and/or the Merger without further shareholder approval
if the Board of Directors determines that the consummation of the Domestication
and/or the Merger would be inadvisable or not in the best interests of ATSI or
its shareholders, or if all of the respective conditions to consummation of the
Domestication and Merger have not occurred within a reasonable period of time.

PROCEEDINGS BEFORE GOVERNMENTAL AUTHORITIES

  ONTARIO REGISTRAR

  The Domestication is subject to the authorization of the OBCA Director
pursuant to Section 181 of the OBCA.  If the special resolution is passed by the
requisite number of Common Shares, ATSI intends to apply to the OBCA Director
for authorization of the Domestication.  The OBCA Director is empowered to
authorize the Domestication if, among other things, the OBCA Director is
satisfied that the Domestication will not adversely affect creditors or
shareholders of ATSI and has set out five conditions in this regard.

                                       25
<PAGE>
 
Under the laws of the State of Delaware:

     (i)    the property of ATSI continues to be the property of ATSI, once
domiciled in Delaware;

     (ii)   ATSI, once domiciled in Delaware, continues to be liable for the
obligations of ATSI prior to the Domestication;

     (iii)  an existing cause of action, claim or liability to prosecution is
unaffected;

     (iv)   a civil, criminal or administrative action or proceeding pending by
or against ATSI may be continued to be prosecuted by or against ATSI after the
Domestication; and

     (v)    a conviction against, or ruling, order or judgment in favor of or
against ATSI prior to the Domestication may be enforced by or against ATSI
after the Domestication.

     Furthermore, pursuant to Section 51 of the Regulations to the OBCA, an
application for authorization of an Ontario company to continue in another
jurisdiction must be accompanied by:

     (i)    a consent from the Corporations Tax Branch of the Ministry of
Revenue;

     (ii)   a consent from the Ontario Securities Commission;

     (iii)  a legal opinion to the effect that the laws of the other
jurisdiction meet the requirements of Section 181 of the OBCA.

  DELAWARE

     Subject to receipt of the authorization of the OBCA Director to the
Domestication, ATSI anticipates that it will file with the Secretary of State of
Delaware a Certificate of Domestication and a Certificate of Incorporation under
Section 388 of the DGCL, and that ATSI will be domesticated in Delaware on the
date that all of the conditions to the Domestication have been satisfied.
Promptly thereafter, ATSI intends to give notice to the OBCA Director that ATSI
has been continued under the laws of Delaware and, pursuant to Section 181 of
the OBCA, request that the OBCA Director issue a Certificate of Discontinuance
bearing the same date as the date shown in the Certificate of Incorporation
issued under the DGCL.

PRINCIPAL REASONS FOR THE DOMESTICATION AND MERGER

     The Domestication and Merger will result in ATSI Merger Corp., a Delaware
corporation, succeeding to all of the operations, assets and liabilities of
ATSI, an Ontario, Canada corporation. The Board of Directors believes that, by
domiciling in the United States, ATSI will be able to enhance shareholder value
over the long term. The Board's belief is based, in part, on the following
factors:

     (i)    by domiciling in the United States, the marketability of the
            Company's Common Shares will be enhanced by raising the Company's
            profile in various capital markets; and

     (ii)   by becoming subject to United States tax laws, it will be provided
            with greater ease in dealing with income tax complexities associated
            with multi-jurisdictional operations.

     Furthermore, in the experience of management, potential debt and equity
capital sources and strategic partners in the United States are more comfortable
dealing with a United States corporation than a foreign corporation.  Management
believes this may be because U.S. entities are likely to be more familiar with
U.S. standards of accounting, U.S. securities law disclosure requirements and
U.S. legal principles.

                                       26
<PAGE>
 
  The Company chose the State of Delaware to be its domicile because Delaware,
like Ontario, has a modern and flexible corporate code.  The escalating risks
and resultant costs of director liability have made it increasingly difficult
for corporations to find and retain competent directors, and the Company
believes the various indemnity and exculpation provisions of the DGCL will help
it to attract and retain competent directors.  Delaware has an active bar which
is continually assessing and recommending improvements to the DGCL, and the
substantial body of settled case law under the DGCL adds greater certainty in
assessing risks associated with conducting business.

  The Company does not believe that there will be any material disadvantages
associated with the Domestication.

  The Company was formed in May 1994 as a result of the amalgamation (the
"Amalgamation") of Willingdon Resources Ltd., an Ontario, Canada corporation
("Willingdon"), with Latcomm International Inc. ("Latcomm"), an Alberta, Canada
corporation organized contemporaneously in December 1993 with its wholly-owned
subsidiary, Latin American Telecomm, Inc., a Texas corporation formed for the
primary purpose of providing private international telecommunications networks
between Latin America and the United States, to carry on the business of Latcomm
as American Telesource International Inc. Prior to the Amalgamation, Willingdon
carried on exploration on its mining property in Northern Ontario, but was
unable to prove up an economic orebody. Because the corporate records relating
to Willingdon's operations prior to the Amalgamation are incomplete, the Company
cannot accurately establish with complete certainty the circumstances
surrounding each and every share issuance. Although the Company has not
identified any defects in share issuances during the period of time prior to the
Amalgamation, and has not been notified that any exist, it intends to undertake
the Merger in an effort to ensure that no such issues arise in the future.
Accordingly, in connection with the Merger, when each shareholder surrenders his
certificate, he will be deemed to be surrendering any and all claims, if any, he
may have against the Company in respect of a defective issuance which he alleges
may have occurred.

  If the Merger is not completed, the Company will not have the same level of
certainty with respect to the circumstances relating to the issuance of the
Common Shares that would be afforded if the Merger were to occur.  The Company
does not believe, however, that it will be adversely affected in any material
way by the failure to complete the Merger.


                 EFFECT OF DOMESTICATION ON SHAREHOLDER RIGHTS

  On the effective date of the Domestication, ATSI will be deemed incorporated
under the laws of the State of Delaware and will be governed by the Certificate
of Incorporation filed with the Certificate of Domestication and the new
Delaware bylaws adopted in connection therewith.  On the effective date of the
Merger (as soon as practicable after the Domestication), ATSI will be merged
into ATSI Merger Corp., the shareholders of ATSI will become stockholders of the
surviving corporation and the surviving corporation will be governed by the
Certificate of Incorporation and Bylaws of ATSI Merger Corp., both of which will
be identical to the Delaware Certificate of Incorporation and Bylaws of ATSI.
Accordingly, because the rights of shareholders of ATSI after the Domestication,
but prior to the Merger will be substantially similar to their post-Merger
rights, the discussion below sets forth the rights of the shareholders of ATSI
following the Domestication, whether or not the Merger occurs.

  Differences between the OBCA and the DGCL and between the ATSI Articles and
the proposed ATSI Merger Corp. Certificate will result in various changes in the
rights of shareholders of ATSI.  The following is a summary of the rights of the
Company's stockholders after the Domestication, as compared with those of ATSI
shareholders prior to the Domestication.  This summary does not purport to be
complete and is qualified in its entirety by reference to the ATSI Merger Corp.
Certificate, ATSI Merger Corp. Bylaws, ATSI Articles and ATSI Bylaws, the text
of which are included in this Prospectus as Exhibits H, I, E and F,

                                       27

respectively.  For further discussion of certain provisions of the ATSI Merger
Corp. Certificate, see "Description of ATSI Merger Corp. Securities."

DIFFERENCES BETWEEN ONTARIO AND DELAWARE CORPORATE LAW

  Upon the consummation of the Domestication and Merger, the Corporation will be
subject to the provisions of the DGCL.  Set forth below is a comparison of
certain material provisions of the DGCL and the OBCA.

  Vote on Extraordinary Corporate Transactions.  Under the OBCA, amalgamations,
continuances, sales or leases or exchanges of all or substantially all of the
assets of a company and other extraordinary corporate actions require the
approval of the holders of two-thirds of the shares being voted thereon in
person or by proxy.  Under the DGCL, mergers or consolidations require the
approval of the holders of a majority of the outstanding stock of the
corporation entitled to vote thereon except: (i) for a corporation that survives
the merger where the merger requires the issuance of Common Stock not exceeding
20% of such corporation's shares outstanding immediately prior to the merger,
the merger agreement does not amend in any respect the survivor's certificate of
incorporation and shareholder approval is not specifically mandated in the
survivor's certificate of incorporation; and (ii) for both corporations where
the corporation surviving the merger was a 90% or greater parent of the other
corporation.  Unless a greater percentage is required by the charter, a sale,
lease or exchange of all or substantially all the property or assets of a
corporation or an amendment to the certificate of incorporation also require the
approval of the holders of a majority of the outstanding stock entitled to vote
thereon.

  Bylaw Amendments.  Under the OBCA, either shareholders or directors may make,
amend or repeal bylaws, but director bylaws are subject to later confirmation by
the shareholders.  Under the DGCL, stockholders may adopt, amend or repeal
bylaws.  In addition, directors of a corporation, if authorized by the
certificate of incorporation, may adopt, amend or repeal bylaws, such action not
being subject to later shareholder confirmation.

  Amendments to the Charter.  Under the OBCA, an amendment to a corporation's
articles of incorporation requires the affirmative vote of at least two-thirds
of the votes cast by shareholders entitled to vote thereon represented in person
or by proxy and in most instances, the affirmative vote of at least two-thirds
of the votes cast within each class or series of outstanding shares by
shareholders represented in person or by proxy.  Under the DGCL, an amendment to
a corporation's certificate of incorporation requires the approval of a majority
of the outstanding stock entitled to vote, unless such level of approval is
increased by the certificate of incorporation.  In addition, under the DGCL, if
the amendment to the certificate of incorporation adversely affects the rights
of a particular class of stock, that class is entitled to vote separately on the
amendment whether or not it is designated as voting stock.

  Removal of Directors.  Under both the OBCA and the DGCL, directors may
generally be removed, with or without cause, by a vote of the holders of a
majority of the shares being voted.  However, under the DGCL, if the board is
classified, which the Board of ATSI Merger Corp. is, directors may be removed
only for cause, unless the certificate of incorporation provides otherwise,
which the ATSI Merger Corp. Certificate of Incorporation does not.  Further, if
a director is elected by holders of a class or series of shares, the OBCA
provides that only the shareholders of that class or series can vote to remove
that director, with or without cause, whereas the DGCL provides that only the
shareholders of that class or series can vote to remove that director without
cause.  Finally, in the case of a corporation having cumulative voting, under
both the OBCA and the DGCL a director may not be removed from office if the
votes cast against the director's removal would be sufficient to elect such
director and such votes could be voted cumulatively at an election at which the
same total number of votes were cast and, (i) in the case of the OBCA, the
number of directors required by the articles were then being elected, or (ii) in
the case of DGCL, the entire board is being elected or, if there are classes of
directors, the class of directors of which such director is a part is being
elected.

                                       28
<PAGE>
 
  Quorum of Shareholders.  Under the OBCA, a quorum for shareholders' meetings
consists of the holders of a majority of the outstanding shares, present in
person or represented by proxy, unless the bylaws otherwise provide.  Under the
DGCL, a quorum consists of a majority of shares entitled to vote, present in
person or represented by proxy, unless the charter or bylaws provide otherwise,
but in no event may a quorum consist of less than one-third of the shares
entitled to vote at the meeting.

  Notice and Calling of Shareholder Meetings.  Under the OBCA, shareholders'
meetings may be called by the board of directors who must call a meeting when so
requested by the holders of not less than 5% of the voting shares, on a minimum
of 21 days' notice.  Under the DGCL, unless the certificate of incorporation or
bylaws authorize additional persons, only the board of directors may call a
shareholders' meeting, on ten days' notice.

  Shareholder Consent in Lieu of Meeting.  Under the OBCA, shareholder action
without a meeting may only be taken by unanimous written consent of all
shareholders.  Under the DGCL, unless otherwise provided in the charter,
shareholders may act by written consent without a meeting if holders of
outstanding stock representing not less than the minimum number of votes that
would be necessary to take such action at an annual or special meeting execute a
written consent providing for such action.

  Appraisal Rights.  The DGCL does not give appraisal rights in a merger or
consolidation to holders of stock listed on a national securities exchange (such
as the Nasdaq National Market) or held of record by more than 2,000
shareholders, provided that such holders receive shares of stock of the company
surviving the merger or consolidation or shares of stock of any other company
which is either listed on a national securities exchange or held of record by
more than 2,000 shareholders.  The OBCA does not contain any similar exemption
from its provisions relating to dissenter's rights of appraisal for
amalgamations.  In addition, appraisal rights are available under the DGCL for
sales of all or substantially all of the Corporation's assets or charter
amendments only if the charter so provides.  Shareholders are entitled to
appraisal rights under the OBCA in connection with the sale, lease or exchange
of all or substantially all the assets of a company and for charter amendments
which affect share issuance or transferability or corporate purposes or which
would require a separate class vote.

  Shareholder Register.  A Delaware company's stock ledger showing the names,
addresses and security ownership of its shareholders may be inspected only by
directors and shareholders of record for a purpose reasonably related to their
respective interests as directors or shareholders.  Shareholders and certain
other persons may inspect the shareholder list of an Ontario company that is an
offering corporation.

  Dividends and Distributions.  The DGCL and OBCA treat dividends similarly.
The DGCL permits a company, unless otherwise restricted by the certificate of
incorporation, to pay dividends out of surplus or, if there is no surplus, out
of net profits for the current and preceding fiscal year (provided that the
amount of capital of the company is not less than the aggregate amount of the
capital represented by the issued and outstanding stock of all classes having a
preference upon the distribution of assets).  In addition, the DGCL generally
provides that a company may redeem or repurchase its shares only if such
redemption or repurchase would not impair the capital of the corporation.  The
ability of a Delaware company to pay dividends on, or to make repurchases of
redemptions of, its shares is dependent on the financial status of the company
standing alone and not on a consolidated basis.  In determining the amount of
surplus of a Delaware company, the assets of the company, including stock of
subsidiaries owned by the company, must be valued at their fair market value as
determined by the board of directors if fair market value is less than
historical book value and may be valued at their fair market value if fair
market value is greater than historical book value.  Under the OBCA, a company
may not declare or pay a dividend if there are reasonable grounds for believing
that the company is or after the payment would be, unable to pay its liabilities
as they become due, or if the realizable value of the company's assets would
thereby be less than the aggregate of its liabilities and stated capital of all
classes.

                                       29
<PAGE>
 
  Director Qualification and Number.  A majority of the directors of an Ontario
company must be Canadian residents.  The DGCL has no similar requirement.  The
number of directors of a Delaware company may be changed by resolution of the
directors if the charter or bylaws so provide (as will be the case with the
proposed ATSI Merger Corp. certificate and bylaws) while the charter of an
Ontario company must specify the number or a range for the number of directors
and if authorized by a special shareholders' resolution, in between
shareholders' meetings, the directors may increase the number of directors
within the minimum and maximum range provided that they may not do so if after
such appointment, the total number of directors would be one and one-third times
greater than the number of directors required to have been elected at the last
annual meeting of shareholders.

  Director Liability.  Under the DGCL, the charter of a Delaware company may
limit the personal liability of a director to the shareholders of the company
for monetary damages for breach of fiduciary duty, except for: (i) any breach of
a director's duty of loyalty to the company or its shareholders; (ii) acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law; (iii) paying a dividend or approving a stock repurchase in
violation of statutory limitations; or (iv) any transaction from which a
director derived an improper personal benefit.  The OBCA has no comparable
provision.  Such a charter provision under the DGCL does not affect the right of
a company or its shareholders to pursue equitable remedies such as an action to
enjoin or rescind a transaction involving a breach of a director's duty of care
(although such equitable remedies may not always be available) and in no way
affects a director's liability under United States federal securities laws.

  Oppression Relief and Equitable Remedies.  The OBCA creates a cause of action
for "oppression" and "unfairness" with respect to shareholders, creditors,
directors and officers and vests the court with broad remedial powers in
connection therewith.  The DGCL contains no comparable provision and the scope
of the equitable powers of the Delaware courts as defined by existing case law
is less certain than the scope of the powers of Ontario courts.

  In addition, certain differences between the powers granted to companies under
the DGCL and the powers granted to companies under the OBCA may make a Delaware
company less vulnerable than an Ontario company to hostile takeover attempts.
These differences include the absence of power of shareholders to call special
meetings unless expressly granted as discussed above.  On the other hand,
because of such provisions as the power of shareholders to take action without a
meeting by less than unanimous consent, the DGCL may, under some circumstances,
facilitate a hostile takeover attempt.

DIFFERENCES BETWEEN THE ATSI ARTICLES AND THE ATSI MERGER CORP. CERTIFICATE

  The ATSI Merger Corp. Certificate to be adopted in connection with the Merger
(and the ATSI Certificate after the Domestication) differ substantially from the
ATSI Articles.  Differences include, but are not limited to, the following:

  Capital Structure.  Under the ATSI Merger Corp. Certificate, the total number
of shares of capital stock that the Company will have the authority to issue is
55,000,000, $0.001 par value per share, consisting of 50,000,000 shares of ATSI
Merger Corp. Common Stock and 5,000,000 shares of ATSI Merger Corp. Preferred
Stock.  Under the ATSI Articles, the Company has the authority to issue
unlimited amounts of no par value stock for common shares.

  Board of Director Size.  The ATSI Merger Corp. Certificate (i) provides for an
initial board of directors consisting of five members but contains no
restrictions on the minimum or maximum number of directors except as provided by
Delaware law and (ii) divides the Board of Directors into three classes, one of
which is elected each year to hold office for a three-year term and until
successors are elected and qualified.  The ATSI Articles provide for a minimum
of three and a maximum of ten directors.  ATSI currently has three directors,
although the ATSI Board will be increased to five members, and will be divided
into three classes,

                                       30
<PAGE>
 
one of which is elected each year to hold office for a three-year term and until
his successors are elected and qualified, under the terms of the Certificate of
Incorporation to be filed pursuant to the Company's Domestication into Delaware.
ATSI Merger Corp. has five directors.  See "Management."

  Liability of Directors.  The ATSI Merger Corp. Certificate provides that
directors of the corporation shall not be personally liable to the corporation
or its shareholders for monetary damages for breach of fiduciary duty as a
director, except that a director may be personally liable to the extent provided
by applicable Delaware law which currently prohibits limitation of director
liability for: (i) any breach of the director's duty of loyalty to the
corporation or its shareholders; (ii) acts or omissions not in good faith or
which involve intentional misconduct or knowing violation of law; (iii)
authorizing the payment of a dividend or repurchase of stock; or (iv) any
transaction from which the director derived an improper personal benefit.  The
ATSI Articles prior to the Domestication contain no similar provision.

  Indemnification.  The ATSI Merger Corp. Certificate provides that ATSI Merger
Corp. will indemnify each director and officer of ATSI Merger Corp. who may be
indemnified, to the fullest extent permitted by Section 145 of the Delaware
General Corporation Law ("Section 145"), as it may be amended from time to time,
in each and every situation where ATSI Merger Corp. is obligated to make such
indemnification pursuant to Section 145.  In addition, ATSI Merger Corp. will
indemnify each of ATSI Merger Corp.'s directors and officers in each and every
situation where, under Section 145, ATSI Merger Corp. is not obligated, but is
permitted or empowered, to make such indemnification.  ATSI Merger Corp. may, in
the sole discretion of the Board, indemnify any other person who may be
indemnified pursuant to Section 145 to the extent the Board deems advisable, as
permitted by such section.  ATSI Merger Corp. will promptly make or cause to be
made any determination which Section 145 requires.  The ATSI Articles prior to
the Domestication contain no similar provision.

  Shareholder Consent in Lieu of Meeting.  As noted previously, under the OBCA,
the shareholders of a corporation may take action without a meeting only by
unanimous consent of all shareholders.  Under the ATSI Merger Corp. Certificate
(and the ATSI Certificate after the Domestication), the shareholders of the
Company will not be permitted to take action without a meeting unless the board
of directors shall have previously approved the taking of such action by written
consent.

  Shareholder Nomination of Directors.  The ATSI Merger Corp. Certificate (and
the ATSI Certificate after the Domestication) will require shareholder
nominations of directors for an election to be held at an annual meeting or
special meeting of shareholders to meet certain procedural requirements
including disclosure of such information regarding the proposed nominees as
would be required to be included in a proxy statement filed pursuant to the
proxy rules of the Commission, a description of all arrangements or any
affiliation between the shareholder and the proposed nominee and the consent of
the nominee to serve as a director of the Corporation if so elected.  Although
such provision is not explicitly provided for in the ATSI Articles prior to the
Domestication, the OBCA contains similar provisions.

  Business Combinations.  After both the Domestication and the Merger, the
Company will be subject to the provisions of Section 203 of the DGCL ("Section
203").  Section 203 provides, with certain exceptions, that a Delaware
corporation may not engage in any of a broad range of business combinations with
a person, or an affiliate or associate of such person, who is an "interested
stockholder" for three years from the date that such person became an interested
stockholder unless:  (i) the transaction resulting in a person becoming an
interested stockholder, or the business combination, is approved by the Board of
Directors of the corporation before the person becomes an interested
stockholder, (ii) the interested stockholder acquired 85% or more of the
outstanding voting stock of the corporation in the same transaction that makes
such person an interested stockholder (excluding shares owned by persons who are
both officers and directors of the corporation, and shares held by certain
employee stock ownership plans), or (iii) on or after the date the person
becomes an interested stockholder, the business combination is approved by the
corporation's board of directors and by the holders of at least 66 2/3% of the
corporation's outstanding voting stock at an annual

                                       31
<PAGE>
 
or special meeting, excluding shares owned by the interested stockholder.  Under
Section 203, an "interested stockholder" is defined as any person who is (i) the
owner of 15% or more of the outstanding voting stock of the corporation or (ii)
an affiliate or associate of the corporation and who was the owner of 15% or
more of the outstanding voting stock of the corporation at any time within the
three years immediately prior to the date on which it is sought to be determined
whether such person is an interested stockholder.

  A corporation may, at its option, exclude itself from the coverage of Section
203 by amending its certificate of incorporation or bylaws by action of its
stockholders to exempt itself from coverage.  The Company has not adopted such
an amendment to its Certificate of Incorporation or Bylaws.  There is no
comparable provision under the OBCA.  For further discussion of the ATSI Merger
Corp. Certificate of Incorporation, see "Description of ATSI Merger Corp.
Securities."


                      DISSENT RIGHTS OF ATSI SHAREHOLDERS

  In addition to any other rights a shareholder may have when a Certificate of
Domestication is filed with the Secretary of State of Delaware pursuant to the
special resolution authorizing a company to be domesticated in Delaware under
the provisions of the DGCL (the "Domestication Resolution"), a shareholder who
complies with the dissent procedure of Section 185 of the OBCA is entitled to be
paid by the Company the fair value of the shares held by him in respect of which
he dissents determined as of the close of business on the day before the
Domestication becomes effective.  The dissent procedure of Section 185 of the
OBCA is summarized below and shareholders who may wish to dissent are
specifically referred to the disclosure set forth below, as failure by such
shareholder to adhere strictly to the requirements of such section may result in
the loss of such shareholder's rights under that section.  Each shareholder who
might desire to exercise these rights of dissent should carefully consider and
comply with the provisions of such section and consult with his legal advisor.

  The following summary is qualified in its entirety by reference to Section 185
of the OBCA, a copy of which is attached as Exhibit J.

BUSINESS CORPORATIONS ACT (ONTARIO)

  A dissenting shareholder may only claim under Section 185 of the OBCA with
respect to all of the shares of a class held by the dissenting shareholder on
behalf of any one beneficial owner and registered in the name of the dissenting
shareholder.

  A shareholder who wishes to invoke the provisions of Section 185 of the OBCA
must send a written objection (the "Objection Notice") to the Domestication
Resolution at or before the meeting at which such resolution is to be
considered.

  The sending of a written objection to the Domestication Resolution does not
deprive the shareholder of the right to vote thereon.  Moreover, the OBCA
specifically provides that the execution or exercise of a proxy does not
constitute a written objection for the purposes of the dissent procedure.

  A vote in favor of the Domestication Resolution or the execution of a proxy
which is so voted, will constitute a waiver of the right of dissent with respect
to such resolution.

  Within ten days of the passing of the Domestication Resolution, the Company is
required to notify in writing each dissenting shareholder that such resolution
has been adopted.

  A dissenting shareholder shall within 20 days after he receives notice of the
adoption of the Domestication Resolution or, if he does not receive such notice,
within 20 days after he learns that the Domestication

                                       32
<PAGE>
 
Resolution has been adopted, send to the Company a written notice (the "Demand
for Payment"), containing his name and address, the number and class of shares
in respect of which he dissents and a demand for payment of the fair value of
the shares of the Company held by him.

  Within 30 days of the sending of the Demand for Payment, the dissenting
shareholder shall send the certificates representing the shares of which he
dissents to the Company or to the Company's transfer agent.  The Company or the
Company's transfer agent shall endorse thereon notice that the holder thereof is
a dissenting shareholder and shall forthwith return the share certificates to
the dissenting shareholder.  A dissenting shareholder who fails to forward an
Objection Notice, Demand for Payment and share certificates within the time
required will lose any right to make a claim to be paid the fair value of his
securities.

  On sending a Demand for Payment, a dissenting shareholder ceases to have any
rights as a shareholder other than the right to be paid the fair value of the
shares held by him, unless (i) the dissenting shareholder withdraws his demand
for payment before the Company makes an offer to pay (the "Offer to Pay"), (ii)
the Company fails to make an Offer to Pay and the dissenting shareholder
withdraws his Demand for Payment or (iii) the directors revoke the Domestication
Resolution, in which case his rights as a shareholder are reinstated as of the
date he sent the Demand for Payment.

  Not later than seven days after the later of the day on which the action
approved by the Domestication Resolution is effective or the day the Company
receives a Demand for Payment, the Company shall send to each dissenting
shareholder who has sent a Demand for Payment, an Offer to Pay for the shares of
the dissenting shareholder in an amount considered by the directors of the
Company to be the fair value thereof, accompanied by a statement showing how the
fair value was determined or a notification that it is lawfully unable to pay
the dissenting shareholders for their shares.  Every Offer to Pay for shares of
the same class or series held by dissenting shareholders for their shares shall
be on the same terms.  Any Offer to Pay accepted by a dissenting shareholder
shall be paid by the Company within ten days of the acceptance but an Offer to
Pay lapses if the Company has not received an acceptance thereof within 30 days
after the Offer to Pay has been made.

  If an Offer to Pay is not made by the Company or if a dissenting shareholder
fails to accept an Offer to Pay, the Company may, within 50 days after the
action approved by the Domestication Resolution is effective or within such
further period as the court may allow, apply to a court to fix a fair value for
the shares of any dissenting shareholder.  If the Company fails to apply to a
court within such 50 day period, the dissenting shareholder may apply to a court
for the same purpose within a further period of 20 days or within such further
period as the court may allow.  Any such application shall be made to the
Ontario Court (General Division).

  A dissenting shareholder is not required to give security for costs in any
application to the court and all dissenting shareholders whose shares have not
been purchased by the Company shall be deemed to be joined as parties and be
bound by the decision of the court.  The Company shall notify each affected
dissenting shareholder of the date, place and consequences of any application
and of the right of a dissenting shareholder to appear and be heard in person or
by counsel.

  The court shall fix a fair value for the shares of all dissenting shareholders
and may in its discretion allow a reasonable rate of interest on the amount
payable to each dissenting shareholder from the date the action approved by the
Domestication Resolution is effective until the date of payment of the amount
ordered by the court.

  If the Company fails to make an Offer to Pay, then the costs of a shareholder
application to the court shall be borne by the Company unless the court
otherwise orders.  In other cases, the cost of any application to a court by the
Company or a dissenting shareholder will be in the discretion of the court.

                             THE 1996 OPTION PLAN

  The Board of Directors unanimously adopted the American Telesource
International Inc. 1996 Stock Option Plan (the "1996 Option Plan") in June 1996
and directed that the 1996 Option Plan be submitted to the shareholders for
their approval.

  The following summary of the 1996 Option Plan is qualified in its entirety by
reference to the text of such Plan, which is set forth in Appendix A.

SUMMARY OF THE 1996 OPTION PLAN

  Under the 1996 Option Plan, options to purchase up to 4,000,000 Common Shares
may be granted to employees and directors of, and consultants and advisors to,
the Company or any subsidiary corporation or entity.  Such number of shares
shall be subject to adjustment to 2,000,000 shares in the event that the
proposed one-for-two reverse stock split of the Company's Common Shares pursuant
to the First Consolidation is approved by the shareholders at the Meeting.  The
1996 Option Plan is intended to permit the Company to retain and attract
qualified individuals who will contribute to its overall success.  Shares that
by reason of the expiration of an option (other than by reason of exercise) or
which are no longer subject to purchase pursuant to an option granted under the
1996 Option Plan may be reoptioned thereunder.  The 1996 Option Plan will be
administered by the Compensation Committee (the "Committee").  The Committee
will set the specific terms and conditions of options granted under the 1996
Option Plan.

  The Company's employees will be eligible to receive either incentive stock
options or nonqualified stock options or a combination of both, as the Committee
determines.  Non-employee participants may be granted only nonqualified stock
options.  Stock options may be granted for a term not to exceed ten years (five
years with respect to a holder of 10% or more of the Company's shares in the
case of an incentive stock option) and are not transferable other than by will
or the laws of descent and distribution.  Each option may be exercised within
the term of the option pursuant to which it is granted (so long as the optionee,
if an employee, continues to be employed by the Company).  In addition, unless a
shorter period is specified in a particular option agreement, an option may be
exercised within three months after the termination of employment of the
optionee (subject to any limitations in the particular option), within one year
after termination in case of termination because of disability, or throughout
the term of the option in the event of the optionee's death, to the extent in
each case the option was exercisable at the termination date.

  The exercise price of all nonqualified stock options must be at least equal to
100% of the fair market value of the Common Shares on the date of grant.  The
exercise price of all incentive stock options must be at least equal to 100% of
the fair market value of the Common Shares on the date of grant, or 110% of the
fair market value with respect to any incentive stock option issued to a holder
of 10% or more of the Company's shares.  Stock options may be exercised by
payment in cash of the exercise price with respect to each share to be purchased
or by delivering Common Shares of the Company already owned by such optionee
with a

                                       34
<PAGE>
 
market value equal to the exercise price, or by a method in which a concurrent
sale of the acquired stock is arranged, with the exercise price payable in cash
from such sale proceeds.

  The 1996 Option Plan provides that each outside director (as defined therein)
will automatically receive a grant of nonqualified stock options for 7,500
shares (3,750 shares as adjusted for the First Consolidation) each year on the
fifth business day following the first public release of the Company's audited
earnings report on results of operations for the preceding fiscal year.  Each
such option will become exercisable in whole or in part on the first anniversary
of the award through the balance of its ten-year term.  Subject to availability
of shares allocated to the 1996 Option Plan and not already reserved for other
outstanding stock options, each outside director who is a member of the Board
immediately following the Domestication (anticipated to be Murray Nye, Terry
Colbert, Tomas Revesz and one additional person to be identified) and each
outside director who joins the Board thereafter will in addition receive an
initial grant of nonqualified options for 75,000 shares (37,500 shares as
adjusted for the First Consolidation), which will become exercisable in four
equal increments (9,375 shares each as adjusted for the First Consolidation)
beginning on the first anniversary of the award and on each of the next three
succeeding anniversary dates.  Such options will be exercisable for a term of
ten years.  Such options will be awarded upon their appointment or election to
the Board.  Options, once granted and to the extent exercisable, will remain
exercisable throughout their term, regardless of whether the holder continues as
a director.  The option exercise price of the options is equal to 100% of the
fair market value of the covered Common Shares at the time of grant.

  The 1996 Option Plan will terminate 10 years after the date such plan was
adopted by the Board of Directors.  The Board of Directors may, however,
terminate the 1996 Option Plan at any time prior to such date.  Termination of
the 1996 Option Plan will not alter or impair, without the consent of the
optionee, any of the rights or obligations pursuant to any option granted under
the 1996 Option Plan.

U.S. FEDERAL INCOME TAX CONSEQUENCES

  The following is a general description of the U.S. federal income tax
consequences of options granted and exercised under the 1996 Option Plan based
upon federal tax law as it exists on the date of this Prospectus.  Statements
made in this description may become inaccurate or incorrect in the event of a
change in U.S. federal tax law.  Each optionee should consult with his or her
own tax advisor with respect to the specific tax treatment of his or her
particular transactions under the Plan.

  INCENTIVE STOCK OPTIONS

  Incentive options issued to employees under the 1996 Option Plan are intended
to qualify as "incentive stock options" under Section 422 of the Internal
Revenue Code of 1986, as amended from time to time (the "Code").  These options
may only be issued to employees.

  Grant and Exercise.  The granting of an incentive stock option is a non-
taxable event.  The exercise of an incentive stock option is also a non-taxable
event provided the option is exercised during the employment of the optionee or
within three months after the optionee's employment has been terminated;
however, the "spread" between the fair market value of the optioned stock and
the exercise price is an adjustment to alternative minimum taxable income and
may be subject to the alternative minimum tax as discussed below.

  Disposition.  The optionee will recognize gain or loss in the year in which
the shares purchased under an incentive option are sold or otherwise made the
subject of disposition.  Generally, a disposition of the purchased shares will
include any transfer of legal title, including a transfer by sale, exchange or
gift, but it will not include (i) a transfer into joint ownership with right of
survivorship if the optionee remains one of the joint owners, (ii) a pledge, or
(iii) a transfer by bequest or inheritance.

                                       35
<PAGE>
 
  For federal income tax purposes, dispositions of incentive option shares are
divided into two categories: (i) qualifying and (ii) disqualifying.  A
qualifying disposition of the purchased shares will occur if the sale or other
disposition is made after the optionee has held such shares for more than two
years after the date the option is granted and more than one year after the date
the particular shares involved in the disposition are transferred to the
optionee.  If the optionee fails to satisfy either of these two holding periods
prior to the sale or other disposition of the purchased shares, then a
disqualifying disposition will result.

  Upon a qualifying disposition, the optionee will recognize gain or loss in an
amount equal to the amount realized upon the sale or disposition, less the
exercise price paid for such shares.  Any gain recognized will generally be
subject to capital gain treatment.  Upon a disqualifying disposition, the
optionee will recognize ordinary income in the year of disposition in an amount
equal to the excess of the fair market value of such shares on the date of
exercise over the exercise price paid for such shares, and the Company will be
required to satisfy reporting and federal tax withholding requirements.  If the
disqualifying disposition is effected by means of an arms-length sale or
exchange to an unrelated party, the ordinary income will be limited to the
amount by which the amount realized, or the fair market value at the date of
exercise, whichever is less, exceeds the exercise price.  The amount of ordinary
income recognized is added to the basis of the stock for purposes of determining
the additional gain, if any, on the disposition of the shares.  If additional
gain is recognized, it will be subject to capital gain treatment.

  Payments in Common Shares.  U.S. Treasury Regulations provide the following
guidelines with respect to the delivery of Common Shares in payment of the
exercise price of an incentive stock option:

     (a)  Disqualifying Disposition of Delivered Shares. The use of Common
  Shares acquired upon the exercise of an earlier granted incentive option to
  exercise an outstanding incentive option will constitute a "disqualifying
  disposition" of the delivered shares if such shares have not been held long
  enough to satisfy the requisite two-year and one-year holding periods
  applicable to incentive options. Such a disposition will generally render the
  optionee subject to ordinary income taxation on the difference between (i) the
  fair market value of the delivered shares at the time of their original
  purchase and (ii) the purchase price paid for such shares. In all other cases,
  no taxable income will be recognized with respect to the delivered shares.

     (b)  Attributes of Purchased Shares Where There Is No Disqualifying
  Disposition. If an incentive stock option is exercised with (i) Common Shares
  acquired under an incentive option and held for the requisite holding periods
  prior to delivery, (ii) Common Shares acquired under a nonqualified option, or
  (iii) Common Shares acquired through open-market purchases, then the optionee
  will not recognize any taxable income with respect to the Common Shares
  purchased upon exercise of the incentive stock option. To the extent the
  purchased shares equal in number the Common Shares delivered in payment of the
  option price, the new shares will have the same basis and holding period as
  the delivered shares. The balance of the purchased shares will have a zero
  basis for tax purposes, and their holding period will commence on the date
  these shares are transferred to the optionee. However, all the purchased
  shares will be subject to the "disqualifying disposition" rules applicable to
  incentive options, and the two-year and one-year holding periods will be
  measured, respectively, from the date the incentive option was granted and the
  date it was exercised.

     (c)  Attributes of Purchased Shares Where There is A Disqualifying
  Disposition of Delivered Shares. If the delivery of shares acquired under an
  incentive option results in a disqualifying disposition pursuant to the
  principles of paragraph (a) above, then the tax basis and holding periods for
  the new shares transferred to the optionee upon exercise of the incentive
  option will be determined as follows:

          1.  To the extent the number of new shares equals the number of
     delivered shares as to which there was a disqualifying disposition, the
     basis for such shares will be equal to the fair market value of the
     delivered shares at the time they were originally purchased and the holding
     period for these

                                       36
<PAGE>
 
     shares will, except for disqualifying disposition purposes, include the
     period for which the delivered shares were held; and

          2.  To the extent the number of new shares exceeds the number of
     delivered shares, these shares will have a zero basis and a holding period
     measured from the date of exercise of the option.

  For disqualifying disposition purposes, all the shares received will be
subject to the two-year and one-year holding period requirements for incentive
option shares, measured, respectively, from the date the incentive option was
granted and the date it was exercised.

  Special Rule.  If the shares purchased under the incentive option are subject
to a substantial risk of forfeiture, such as the insider trading restrictions of
Section 16(b) of the Exchange Act, the amount of ordinary income recognized by
the optionee upon a disqualifying disposition will be based upon the fair market
value of such shares on the date such risk of forfeiture lapses rather than the
date the option is exercised.  In the absence of final U.S. Treasury regulations
relating to incentive options, it is not certain whether such result can be
avoided by making a conditional election pursuant to Section 83(b) of the Code
at the time the incentive option is exercised.

  Federal Tax Rates.  On the date of this Prospectus, income is subject to a
maximum U.S. federal tax rate of 39.6% and net capital gains are subject to a
maximum U.S. federal tax rate of 28%.

  Alternative Minimum Tax.  Unless the optionee makes a disqualifying
disposition or his rights are not fully transferrable or subject to a
substantial risk of forfeiture, the amount by which the value of the optioned
stock at the time of exercise exceeds the option price will increase the
optionee's alternative minimum taxable income in the year the option is
exercised.  If the optionee makes a disqualifying disposition in the year in
which the option is exercised, the maximum amount that will be included in
alternative minimum taxable income is the gain on the disposition of the stock.
Income triggered by a disqualifying disposition in a year other than the year of
exercise will not affect the optionee's alternative minimum taxable income.

  The alternative minimum tax will be equal to 26% of the amount by which the
optionee's taxable excess does not exceed $175,000 ($87,500 in the case of a
married taxpayer who files a separate return) plus 28% of the amount by which
the optionee's taxable excess exceeds $175,000 ($87,500 in the case of a married
taxpayer who files a separate return).  The optionee's "taxable excess" is the
amount by which the optionee's alternative minimum taxable income exceeds the
optionee's exemption amount which is $45,000 for married individuals filing
jointly, $33,750 for single individuals and $22,500 for married individuals
filing separately.

  The allowable exemption from the alternative minimum tax is reduced by 25% of
the excess of an individual's alternative minimum taxable income for the year
over $150,000 for a married taxpayer filing a joint return, $112,500 for an
unmarried taxpayer, and $75,000 for a married taxpayer filing a separate return.

  A married taxpayer who files a separate return must increase his alternative
minimum taxable income by the lesser of (i) 25% of the excess of alternative
minimum taxable income (determined without regard to this sentence) over
$165,000 or (ii) $22,500.

  For purposes of determining an individual's alternative minimum taxable income
(but not regular taxable income) for any subsequent year in which the shares are
sold, the basis of such shares will be their fair market value at the time the
incentive stock option was exercised.  If an individual pays alternative minimum
taxes for one or more taxable years after December 31, 1986, the amount of such
taxes (subject to certain adjustments and reductions) will be applied as a
partial credit against the individual's regular tax liability (but not
alternative minimum tax liability) for subsequent taxable years.

                                       37
<PAGE>
 
  Employer Deduction.  If the optionee makes a disqualifying disposition and the
Company complies with reporting requirements, then the Company will be entitled
to an income tax deduction equal to the amount by which the fair market value of
such shares on the date of exercise exceeded the option exercise price.  The
deduction will only be allowed for the Company's taxable year in which the
optionee makes a disqualifying disposition.

Nonqualified Stock Options

  Options issued under the 1996 Option Plan which are intended not to qualify as
incentive stock options are referred to herein as "nonqualified stock options."

  The taxability of nonqualified stock options is governed by Section 83 of the
Code.  The recipients of nonqualified stock options will not be taxed upon the
grant of such options, because such options, which will not be actively traded
on an established market, have no readily ascertainable fair market value.  The
optionee will, in general, recognize ordinary income in the year in which the
nonqualified option is exercised, equal to the excess of the fair market value
of the purchased shares at the date of exercise over the exercise price, and the
Company will be required to satisfy federal reporting and tax withholding
requirements.  If the shares purchased by an optionee are subject to the insider
trading restrictions of Section 16(b) of the Exchange Act, taxation of the
income may be deferred from the date of exercise to the date the optionee
becomes free to sell the shares without liability under Section 16(b).  An
optionee subject to Section 16(b) restrictions may, however, elect under Section
83(b) of the Code to include as ordinary income in the year of exercise the fair
market value of the shares received on the date of exercise.  The Section 83(b)
election must be made within 30 days following the date the nonqualified stock
option is exercised, and if made, the optionee will not recognize additional
income at the time the shares may first be sold free of the Section 16(b)
restrictions.  The Company will generally be entitled to an income tax deduction
equal to the amount of ordinary income recognized by the optionee in connection
with the exercise of the nonqualified option, provided the Company complies with
applicable reporting requirements.  The deduction will only be allowed for the
Company's taxable year in which ordinary income is recognized by the optionee.

  If the option price under any nonqualified option is paid in the form of
Common Shares previously acquired either upon the exercise of stock options
(incentive, if held for the requisite holding period, or nonqualified) or
through open-market purchases, then the optionee will not recognize any taxable
income to the extent that the Common Shares received upon the exercise of the
option equal the number of Common Shares delivered in payment of the option
price.  For federal income tax purposes, these newly acquired shares will have
the same basis and holding period as the delivered shares.  The fair market
value of additional Common Shares received upon the exercise of the nonqualified
option will, in general, have to be reported as ordinary income for the year of
exercise, and the Company will be required to satisfy federal reporting and tax
withholding requirements.  These additional shares will have a tax basis equal
to such fair market value, and their holding period will, in general, be
measured from their date of transfer to the optionee.

  In the event an optionee surrenders an exercisable option in exchange for a
cash payment from the Company, the optionee will recognize ordinary income equal
to the amount of the cash payment due the optionee (before required income tax
withholding). The Company will generally be entitled to an income tax deduction
equal to the amount of ordinary income recognized by the optionee in connection
with the surrender of the option, provided the Company complies with applicable
reporting requirements. The deduction will only be allowed for the Company's
taxable year in which ordinary income is recognized by the optionee.

  The affirmative vote of a majority of the Common Shares present and entitled
to vote at the Meeting is required to approve the 1996 Option Plan.  Appendix A
to this Prospectus contains the text of the 1996 Option Plan to be submitted to
the shareholders at the meeting.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS


     The following discussion and analysis should be read in conjunction with
the financial statements and notes thereto included elsewhere in this
Prospectus. The Company's historical financial statements have been prepared on
a accrual basis in accordance with U.S. GAAP, and the financial information
utilized in the following discussion and analysis is presented in U.S. dollars.

OVERVIEW

     American Telesource International Inc. provides international
telecommunications networks for voice, data, fax and video transmission via
satellite between the United States and Latin America and within Latin America,
and call services for domestic and international long distance.

     The Company began operations in December of 1993, and first generated
revenues in April 1994. Since that time, monthly revenues have increased from
approximately $17,000 to approximately $1.3 million in March 1996. Such rapid
growth in revenue has resulted primarily from the provision of operator services
to customers in the United States and Mexico, which in March 1996 represented
94% of the total revenues. The remainder of the Company's revenue has come
primarily from the sale, installation and monthly maintenance of satellite-based
international private networks. The Company seeks to expand its revenues and
customer base from internal growth, primarily through direct sales and marketing
efforts and an agent sales network.

     Since its inception, the Company's near-term strategy has been to position
itself to take advantage of the deregulation of the Mexican telecommunications
industry.  The Company believes that significant opportunities to provide call
services within Mexico and between Mexico and the U.S. will arise from the law
written into effect in June 1995 by the Secretaria de Communicaciones y
Transportes ("SCT"), which provides for the methods by which companies can apply
for concessions and licenses to establish and operate telecommunications
services businesses within Mexico.  This law is, effectively, the first step in
the deregulation of the telephone industry within Mexico.  It also formalizes
the methods by which companies such as ATSI may compete against Telefonos de
Mexico ("Telmex"), the privately owned telecommunications monopoly in Mexico.
However, there can be no assurance that the deregulation of the Mexican
telephone industry will continue and, if so, that such deregulation will occur
to an extent that will provide ATSI opportunities to provide additional call
services within Mexico and between Mexico and the U.S.  See "Business--ATSI-
Mexico."

     The Company has built an international long distance operator services
customer base in Mexico through the use of a small direct sales force and
independent marketing representatives.  Additionally, the Company has developed
an operator services customer base in the United States; however, because the
Company believes that international long distance will continue to grow at a
faster rate and provide higher revenue and gross profit per minute than domestic
long distance, the Company intends to decrease its efforts toward providing
operator services in the United States in the fourth quarter of fiscal 1996 and
increase its focus on the international long distance market, and, as a result,
the Company does not foresee significant growth of this portion of its revenue
base.  The Company has also focused direct sales efforts on international
private networks between the United States and Latin America.

     By providing international operator services to hotels and properties in
major tourist areas of Mexico, the Company has been able to quickly generate
high volume business. The Company has complemented this business with the higher
margin, relatively low monthly revenue business generated by the international
private networks. As regulatory environments permit in Latin America, the
Company anticipates that it will benefit from the synergy of its long distance
and private networks by transporting international long distance traffic over
its own satellite-based network. However, there can be no assurance that
adequate, if any, deregulation

                                       42
<PAGE>
 
will occur and, if so, that the Company will be able to benefit from any such
business synergy.  See "Business."

     The Company provides international telecommunications networks through
utilization of its teleport and switching facility in San Antonio, Texas (the
"Teleport").  Typically, the Company installs its own equipment on a customer's
foreign premises.  This equipment is used to send and/or receive signals from
the Teleport via the Solidaridad Satellite System ("Solidaridad"), which
satellite system is owned by Telecomunicaciones de Mexico ("Telecomm").  The
Company provides fiber optic integration into U.S.-based private and public
telecommunications networks from its Teleport for its customers via a fiber
optic link to a facility in downtown San Antonio, where all major long distance
carriers have a point of presence.  The Company considers itself to be the owner
of that portion of the network between the customer's premises and the point at
which the signal is integrated into a third party's network.  Any costs
associated with connecting to or utilizing third party carriers is considered to
be a direct cost of services.  The Company must pay a tariff to Telecomm for
utilization of Solidaridad, which cost is passed through on a dollar-for-dollar
basis to the customer.  As a result, revenues from private network customers are
recorded net of any associated tariffs paid.  Due to the increasing volume of
traffic transported by the Company over Solidaridad, the Company anticipates
becoming a licensed agent for Telecomm during calendar 1996, thus allowing the
Company to earn commissions from Telecomm on future network traffic.

     Cost of services related to operator services includes primarily those
costs associated with originating and terminating calls which pass through the
Company's switch and operator center (collectively referred to as "transmission
costs"), commissions paid to properties which subscribe to the Company's
services or their representatives, wages and benefits paid to operators and
costs of billing those calls.

     Since its inception, the Company has provided long distance services for
calls originating from Mexico without the benefit of laws in Mexico requiring
Telmex to resell its available network capacity to other carriers at a wholesale
price. Although the Company has contracted with major U.S. carriers to originate
calls from Mexico, Telmex has on occasion refused to provide those services to
those carriers. Telmex has also increased per minute charges to those carriers,
and, consequently, those carriers have increased per minute charges to the
Company, the result of which has been a rapidly changing, and often increasing
cost structure relative to the Company's international long distance services.

     The Company, through ATSI-Mexico, has applied or intends to apply to the
SCT for several licenses, which, if obtained, the Company believes will enable
it to expand significantly its call services business in Mexico by, among other
things, permitting the Company to purchase Telmex network capacity at a more
stable wholesale price. However, there can be no assurance that such licenses
will be obtained, and, if obtained, that such licenses will enable the Company
to expand operations or increase revenue in Mexico. See "Business--ATSI-Mexico."

     Because of the rapid growth of ATSI's customer base and the uncertainties
surrounding the regulatory environment in Mexico during the past two years, the
Company's results of operations in any reporting period may not be directly
comparable to (i) its results of operations in other reporting  periods or (ii)
the results of operations of other telecommunications companies operating in the
United States or Mexico.

     Operating revenues.  Operating revenues for the six-month period ended
January 31, 1996 increased approximately $3.6 million, or 275%, when compared to
the same period in the prior year.  Operating revenues attributable to new
operator services locations contributed approximately $3.2 million, or 89%, of
this growth.  The number of operator service calls processed by the Company
increased to 302,014 during the six months ended January 31, 1996, as compared
to 107,976 for the same period ended January 31, 1995, representing an overall
increase in call volume of 180%.  Additionally, growth in the percentage of
calls handled by the Company which originated in Mexico and terminated in the
United States (referred to hereinafter as "Mexico International Calls")
increased from 17% during the six months ended January 31, 1995 to 23% for the
same period ended January 31, 1996.  During the six-month period ended January
31, 1996, revenue from Mexico International Calls averaged in excess of $30 per
call, while revenue from domestic U.S. calls averaged less than $7 per call.
See "Business--Long Distance Call Services."

     Subsequent to January 31, 1995, the Company implemented several call
services which also contributed to the growth in revenues between the six-month
periods ended January 31, 1996 and 1995. In June 1995 the Company began
distributing calling cards to Visa cardholders issued by the Bank of Brazil.
These cards may be used by Brazilians traveling outside of their native country,
but primarily in the United States, for calling within the United States or to
other world-wide destinations. Additionally, in November 1995 the Company began
providing service to cellular telephone customers of a Mexican based cellular
company with in excess of 40,000 subscribers, which service enables subscribers
to access the Company's network when traveling in the United Sates for the
purpose of placing cellular calls domestically within the United States or
internationally to Mexico. The Company also expanded its international operator
services to locations in Jamaica in October 1995. Collectively, the above-
mentioned services accounted for approximately 9% of the Company's operator
services revenues for the six-month period ended January 31, 1996. See 
"Business--Long Distance Call Services."

     Revenues generated from private network services increased $409,833, or
266%, from the six-months ended January 31, 1995 to the same period ended
January 31, 1996. Included in this amount is the sale and installation of an
approximately $200,000 private network, which was completed in January 1996. As
of January 31, 1996, the Company had nine private network customers generating
monthly services fees, as compared to two such customers as of the same date in
1995.

     Cost of services. Cost of services increased 239%, or approximately $2.9
million, from the six months ended January 31, 1995 to the six months ended
January 31, 1996. The majority of the Company's direct costs are variable.
Commissions paid to properties which utilize the Company's operator services are
based on

                                       44
<PAGE>
 
revenues generated, and therefore increased significantly between periods.
Transmission costs are incurred on each minute of traffic carried by the
Company.  However, the increased volume of traffic allowed the Company to
benefit from volume-related discounts from carriers, and also allowed the
Company's operator center to function more efficiently.  As a result, overall
cost of services decreased as a percentage of overall revenues.

     During the six-month period ended January 31, 1996, the Company
incurred costs ranging from $0.35 to in excess of $1.50 per minute to transport
completed and non-completed calls from Mexico to its operator center in San
Antonio.  The Company will continue to process these calls under varying cost
scenarios until such time as it receives licenses from the SCT, and
interconnection agreements and prices are established and implemented with
Telmex.  There can be no assurance, however, that ATSI will receive any such
licenses and, if received, that ATSI will be able to establish interconnection
agreements and/or arrange for a more stable price structure.

     Gross Profit.  The Company's gross profit margin increased from 8% to
17% from the six-month period ended January 31, 1995 to the same period ended
January 31, 1996.  The improved margin is a result of several factors.  As the
Company produces larger traffic volumes, the Company becomes more efficient, and
its fixed cost components become smaller as a percentage of overall revenue.
The cost of operators, for example, decreased as a percentage of revenues from
15.6% during the six months ended January 31, 1995 to 8.4% during the six months
ended January 31, 1996.   Each operator was able to handle more calls during a
shift in the six months ended January 31, 1996 as compared to the six months
ended January 31, 1995.  As discussed previously, the number and percentage of
calls, and consequently revenues, from Mexico International Calls also increased
from the six months ended January 31, 1995 to the six months ended January 31,
1996.  Mexico International Calls typically produce a higher margin than
domestic calls made within the United States.  The increased overall traffic
volumes have also allowed the Company to negotiate lower costs for transporting
the calls it handles.

     Selling, General and Administrative.  SG&A expenses rose 118%, or
approximately $1.1 million, from the six-month period ended January 31, 1995 to
the same period ended January 31, 1996.  However, these expenses decreased as a
percentage of revenues from 74% in the six-month period ended January 31, 1995
to 43% in the same period ended January 31, 1996.  Due to economies of scale,
the Company anticipates SG&A expenses to continue to decline as a percentage of
revenues; however, there can be no assurance that such a decline will continue.
The Company's teleport and switching facility in San Antonio (the "Teleport")
became fully operational subsequent to January 31, 1995.  The facility was
modularly built, thereby enabling expansion of the system to process additional
volumes of traffic in a cost-efficient manner.  See "Business--ATSI's
International Teleport & Network Control Center."

     The Company's San Antonio-based headquarters has grown from 32 employees at
January 31, 1995 to 67 employees at April 30, 1996. In March 1996, the Company
negotiated the lease of an additional 5,400 square feet of office space to
provide for further growth in its San Antonio work force. The majority of the
Company's anticipated growth in administrative expenses is expected to occur in
relation to ATSI-Mexico. The Company has incurred expenses related to this
entity since June 1995, and its Mexico City headquarters is expected to become
fully operational in May 1996. The Company expects ATSI-Mexico to become a
center for sales, marketing, maintenance and customer service for its business
in Mexico.

     Depreciation and amortization.  Depreciation and amortization grew
approximately $71,000, or 139%, from the six-month period ended January 31, 1995
to the six-month period ended January 31, 1996, primarily due to the completion
of the Company's Teleport.  However, depreciation and amortization as a percent
of revenues remained relatively flat at approximately 4% and 3%, respectively,
for both such periods.

                                       45

     Loss from Operations. The loss from operations increased approximately
$500,000 from $910,000 for the six months ended January 31, 1995 to $1.41
million for the same period ended January 31, 1996 due to the above factors.

</TABLE>

     Operating revenues. Operating revenues increased approximately $4.5 million
from the fiscal year ended July 31, 1994 to the fiscal year ended July 31, 1995.
During this time, the Company's private network customer base grew from a single
customer generating $17,334 in monthly revenues to five customers producing
$43,220 in monthly revenues. The Company initially provided operator services in
May 1994 for a resort property in Cancun, Mexico. As of July 31, 1995, the
Company's operator services division was servicing in excess of 5,600 rooms and
1,900 public telephones in the United States and Mexico. Approximately 33% of
the operator services revenues for the year ended July 31, 1995 were generated
from calls originating in the United States. The Company gained regulatory
approval to process interstate calls originating in the United States on
September 8, 1994. During 1995, the Company gained the authority to process
intrastate calls in 15 states. As of July 31, 1995 the majority of the Company's
domestic operator services revenues were being produced by payphones located in
Virginia and Michigan, hotels and payphones in Florida and Texas, and casinos
located in Mississippi and Louisiana. The remaining 67% of the operator services
revenue for fiscal 1995 were produced by calls originating outside the United
States. Utilizing a bilingual and bicultural direct sales staff, as well as
independent marketing representatives, the Company was able to establish and
grow customer bases in the following major tourist destinations in Mexico:
Cancun, Cozumel, Cabo San Lucas, Guadalajara and Puerto Vallarta.

     Cost of services. As the Company's customer base grew, the cost of
providing those services grew at a correlative rate from $201,000 in fiscal 1994
to $4.06 million in fiscal 1995. Although the Company had contracted with MCI to
transport its operator services calls from Mexico to its operator center in San
Antonio, Telmex began refusing such services to MCI in July 1994. During the
1995 fiscal year, the Company originated calls from Mexico through a combination
of MCI's network and utilization of Telmex's network.

                                       46
<PAGE>
 
At times this methodology proved neither reliable nor cost effective. MCI was
unable to guarantee reliable services, and subsequently increased prices during
the year ended July 31, 1995 by more than 50%. As a result, the Company utilized
direct dial services offered by Telmex, which were less costly due to the
devaluation of the peso, but more difficult for the Company to monitor and
administer.

     Gross Profit.  The Company's gross profit margin decreased from 17% for the
period ended July 31, 1994 to 15% for the year ended July 31, 1995. This was due
to the increased percentage of overall revenues generated by operator services
as compared to private network services.

     Selling, General and Administrative.  SG&A expenses also grew throughout
fiscal 1995 to approximately $2.6 million from approximately $373,000 in fiscal
1994, as the Company completed the buildout of its Teleport; however, such
expenses steadily decreased as a percentage of overall revenues. The largest
increase was in the provision for bad debt related to the Company's operator
services calls. Throughout fiscal 1995, the Company provided for uncollectible
operator services revenues at the rate of 8% in anticipation of the rates to be
charged by local exchange carriers ("LEC's") who ultimately bill and collect on
the calls processed by the Company. The LEC's charge an average rate for the
initial six to eighteen months, and then "true-up" these rates based upon actual
results. The net effect of the "true-ups" has been positive subsequent to July
31, 1995.

     Depreciation and amortization.  Depreciation and amortization increased
$130,085 between the years ended July 31, 1994 and 1995 as the Company steadily
completed the buildout and increased utilization of its Teleport.

     Loss from Operations.  The loss from operations increased approximately
$1.66 million from $343,000 for the fiscal year ended July 31, 1994 to
approximately $2 million for the fiscal year ended July 31, 1995 due to the
above factors.

LIQUIDITY AND CAPITAL RESOURCES

     The Company's liquidity requirements arise from working capital needs,
primarily the maintenance and growth of its satellite network and switching
capacity and cost of services. The Company has relied primarily on private
equity placements to fund its operations since its formation in December 1993.
From that time through July 31, 1994, the Company generated $922,835 in cash
from its founding shareholders in the form of a private placement. An additional
$294,067 was generated by warrants and options which were exercised. During this
time, $617,645 was spent on the buildout of the Company's Teleport and $426,893
was used to fund its operations, resulting in a cash balance of $117,540 and net
working capital of $113,637 at July 31, 1994.

     The Company's cash position remained relatively constant during the fiscal
year ended July 31, 1995. The Company generated approximately $2.0 million in
cash through private placements and warrant conversions during the fiscal year,
of which approximately $1.3 million was used in the operation of the Company. An
additional $858,616 was used to purchase equipment utilized in the Company's
Teleport. The Company also generated approximately $175,000 through the issuance
of promissory notes to two of its shareholders in 1995, of which one 12%
convertible promissory note in the amount of $100,000, due on July 1, 1996,
remains outstanding. See "Description of ATSI Merger Corp. Securities--Warrants
and Convertible Securities." During this period, the Company did not obtain any
long-term financing to assist it in the purchase of assets. As such, the
Company's working capital position declined to a deficit of $446,370 at July 31,
1995.

     For the six months ending January 31, 1996, the Company generated negative
cash flow from operations of $104,989 and produced $817,062 of net cash proceeds
from private equity placements. In December 1995, the Company signed a contract
with a company in Mexico which called for the sale and installation of a private
network for a total price of approximately $1.4 million. Terms of the contract
called for the Company to receive 60% of such amount upon signing the contract,
which resulted in a net increase in deferred revenue of approximately $733,000
for the six-month period ended January 31, 1996. During this time, approximately

                                       47
<PAGE>
 
$135,568 in cash was spent on the purchase of fixed assets related to further
buildout of the Company's Teleport, as the Company's working capital position
decreased further to a deficit of approximately $1.3 million.

     The Company anticipates that it will continue to undertake to raise money
from time-to-time in private financings, although there can be no assurance that
such private financings will be completed or in sufficient amounts. In addition
to the capital raised from private placements of the Company's equity, the
Company has utilized amounts received from the advanced funding program which it
utilizes to sell its operator services receivables to satisfy vendors. The
Company currently receives in excess of 70% of the value of its receivables
within five days of generating the revenues. The remaining 30% is received, net
of fees and uncollectible amounts, over periods ranging from 30 to 75 days after
the associated revenue is generated.

     Until the Company, if ever, is able to generate positive cash flow from its
operations, or until the Company is able to borrow material amounts from
financial institutions, the Company will be dependent upon its shareholders
and/or its ability to complete private equity placements in order to fund its
current working capital deficit and monthly cash flow deficits.  There can be no
assurances, however, that the Company will be able to achieve future revenue
levels sufficient to support operations or that such equity offerings or other
financing arrangements will actually be consummated or that such funds, if
received, will be sufficient to support existing operations until revenue levels
are achieved sufficient to generate positive cash flow from operations.  These
matters raise substantial doubt about the Company's ability to continue as a
going concern.  The Company's ability to continue as a going concern is
dependent upon the ongoing support of its stockholders, customers and its
ability to obtain capital resources to support development operations.  See
"Notes to Consolidated Financial Statements-Note 2."  During the period ended
January 31, 1996, the Company was able to obtain long-term leasing arrangements
in order to assist it in purchasing equipment for its Teleport.  As of March 31,
1996 the Company had approximately $280,000 outstanding under these
arrangements.  The independent accountants report on the Company's financial
statements for the year ended July 31, 1995 contains an explanatory paragraph
regarding the Company's ability to continue as a going concern.  See Report of
Independent Accountant's contained in, and Note 2 to, the Financial Statements
for the year ended July 31, 1995.

     The Company has contracted with Boles & Company, Inc., an investment
banking entity of which Terry Colbert, a director of ATSI Merger Corp., is a
partner, to assist it in finding a long-term strategic investment partner to
help it meet its working capital and growth needs. If successful (of which there
can be no assurance), planned expenditures relate to the buildout of a teleport
facility in Mexico, the purchase and installation of public coin phones in
strategic locations throughout Mexico, as well as the distribution and sale of
international travel cards to be used throughout Latin America and the United
States.

     As of April 30, 1996 the Company had warrants outstanding to purchase
approximately 5 million Common Shares which, if exercised, would generate
approximately $4.57 million in cash proceeds for the Company's use.  See
"Description of the ATSI Merger Corp. Securities."

INFLATION/FOREIGN CURRENCY

     Inflation has not had a significant impact on the Company's operations.
With the exception of a portion of the $1.4 million contract mentioned above for
the sale and installation of a private network in Mexico, all of the Company's
contracts call for payments to be made in U.S. dollars. The devaluation of the
Mexican peso over the past two years has not had a material adverse effect on
the Company's financial condition or operating results. Conversely, the
devaluation has stimulated tourism in Mexico, which is a primary source of the
Company's operator services revenues.

                                       48

SEASONALITY

     As the portion of the Company's revenues which are generated from tourists
in Mexico continues to increase, so does the effect of seasonality on the
Company's long distance services business. The Company's operator services
revenues are typically higher on a per phone basis during the peak tourism
months in Mexico of January through July than in the remaining months of the
year.

                                    BUSINESS

     American Telesource International Inc. provides international
telecommunications networks for voice, data, fax and video transmission via
satellite between the United States and Latin America and within Latin America,
and call services for domestic and international long distance.  The Company has
chosen to concentrate on the niche market of Latin America because it believes
that the recent privatization of many of the region's major telephone companies
and overall trend towards deregulation, particularly in Mexico where the Company
has focused the majority of its initial efforts, present significant
opportunities to provide international telecommunications services to, from and
within this fast-growing market.  ATSI is able to provide United States
telecommunications standards of reliability and connectivity to the Latin
American region, where telecommunications services remain limited and unreliable
in many areas due to poor local infrastructure, through its San Antonio, Texas-
based satellite teleport (the "Teleport").

     The Company was formed in May 1994 as a result of the amalgamation (the
"Amalgamation") of Willingdon Resources Ltd., an Ontario, Canada corporation
("Willingdon"), with Latcomm International Inc. ("Latcomm"), an Alberta, Canada
corporation organized contemporaneously in December 1993 with its wholly-owned
subsidiary, Latin American Telecomm, Inc. (now ATSI-Texas), a Texas corporation
formed for the primary purpose of providing international telecommunications
networks between Latin America and the United States, to carry on the business
of Latcomm as American Telesource International Inc.  Prior to the Amalgamation,
Willingdon carried on exploration on its mining property in Northern Ontario,
but was unable to prove up an economic orebody.  Willingdon paid down various of
its outstanding liabilities prior to the Amalgamation, and also transferred all
of its remaining assets to a wholly-owned subsidiary, which was subsequently
spun off to its shareholders.  As a result, at the time of the Amalgamation
Willingdon had no material assets and only one material liability in the amount
of approximately $55,000, which debt was assumed by the Company.  ATSI assumed
no other assets or liabilities of Willingdon; however, ATSI succeeded to all of
the assets and liabilities of Latcomm.

     The Company commenced operations with network management services in April
1994, and expanded to long distance call services in May 1994.  In June 1995
American Telesource International de Mexico, S.A. de C.V. ("ATSI-Mexico") was
formed to aid the Company in the provision of long distance and private network
services within Mexico and internationally.  ATSI's mission is to become a full-
service international telecommunications carrier providing private line, direct
dial and other long distance and value added network services between and within
Latin America and the U.S.

NETWORK MANAGEMENT

Overview

     ATSI offers domestic and international private-line telecommunications
services via satellite between the United States and Latin America and within
Latin America to commercial customers for a number of applications.  These
applications generally involve creating private international point-to-point
communications links for clients who need special services, such as heavy data
and voice usage at lower cost and greater dependability.  In addition, ATSI
offers telecommunications hauling capacity via satellite into the U.S. to
domestic and regional communications carriers in Latin America.  The Company
believes that as Latin American markets continue to develop and as multi-
national corporations globalize and expand into the region, the demand for
customized telecommunications services between the United States and Latin
America and within Latin America, as well as for communications transmissions
into the U.S., will continue to grow.

     ATSI anticipates that the demand for international satellite services in
the business communications market and carrier services market will grow
substantially in the foreseeable future, particularly within the Latin American
region. This growth is expected to result from (i) continuing deregulation of
telecommunications markets in Latin America, (ii) continuing technological
advancement, (iii) economic development in Latin

                                       50
<PAGE>
 
America, and (iv) the increasing globalization of business.  However, there can
be no assurance that demand for international satellite services will grow as
anticipated, if at all.

     ATSI provides modern telecommunications standards of reliability and
connectivity to the Latin American region from its Teleport via the Hughes
built, Mexican owned and operated Solidaridad Satellite System ("Solidaridad").
Solidaridad consists of the Solidaridad I and II satellites, which are replacing
the older Mexican Morelos Satellite System.  Solidaridad I and II were
successfully launched into orbit in November 1993 and the fourth quarter of
1994, respectively.  These satellites have increased capacity for
telecommunications services (i.e., "C," "Ku" and "L" bands) and define ATSI's
market, covering portions of North America, all of Mexico, the Carribbean Basin 
and Central America, and the western portion of South America.

     ATSI entered into an agreement with Telecomunicaciones de Mexico
("Telecomm") in October 1995 to purchase transponder services on Solidaridad for
a period of five years (the "Solidaridad Agreement"). The Company chose Telecomm
based upon its favorable transmission rates and Solidaridad's area of satelite
coverage. Pursuant to the Solidaridad Agreement, ATSI pays a tariff to Telecomm
based upon the amount of satellite capacity it uses. Telecomm offers a volume
discount to users of 10 Megahertz of capacity or more. As of May 1996, ATSI
leased 13.8 Megahertz of capacity on Solidaridad. The following charts display
the Company's areas of satellite coverage.

Regions 2,3 and 5. Solidaridad's coverage footprint of Region 2 includes cities
on the southwestern border of the United states, all of Mexico and Central
America, the Caribbean Basin and the northern portion of South America. Its
coverage footprint of Region 3 includes the western portion of South America,
and its footprint of Region 5 covers parts of the midwestern, eastern and
southern regions of the United States, as well as the San Francisco Bay Area.
Solidaridad's coverage of Regions 2,3 and 5 is more fully described in the
following three pages.

Private Networks

     ATSI offers domestic and international private telecommunications networks
via satellite between the U.S. and Latin America and within Latin America for
voice and fax communications, data transmission, point-to-point
videoconferencing links and value added network services, such as credit card
processing, Internet, E-Mail and reservation networks. ATSI also intends to
offer frame relay services.

     Satellite technology's accessibility in remote areas, its distance-
insensitivity and its ability to be rapidly deployed have encouraged its use for
specialized private telecommunications networks.  Private business network users
utilizing satellites rather than ground-based transmission media enjoy the
following additional advantages:

     .  greater reliability, including increased network availability and lower
        transmission error rates;

     .  cost savings for large, geographically dispersed networks;

     .  independence from telephone companies;

     .  predictability of costs over a long period through fixed-rate contracts;

     .  flexibility in changing and adding remote locations to a network; and

     .  integrated network management and control of all remote locations.

     Many businesses and organizations currently use satellite communications
networks for certain of their communications needs.  For example, retail chains
use satellite business communications networks for rapid credit card
authorization and inventory control.  Banks use satellite networks to connect
automated teller machines to processing computers.  News agencies use satellite
networks to distribute information continuously to numerous locations, and
paging companies use satellite networks to distribute paging information from a
central switch to multiple remote transmitters for retransmission to pagers.

     ATSI provides end-to-end very small aperture terminal ("VSAT") private
network satellite services via Solidaridad between the United States and Latin
America and within Latin America for its business communications customers. The
Company's fiber-optic and satellite transmission capabilities enable its
customers to bypass limited telecommunications services which remain in many
areas of Latin America. VSAT networks consist of very small (e.g., 1.8 to 3.8
meters) rooftop antennas and are utilized by customers that need a network over
which to send communications and data transmissions at any time. Through the use
of VSAT technology and sophisticated software, these networks can be served with
a relatively small amount of satellite capacity. Generally, the user pays for
this service based on the capacity leased regardless of volume of use.

     In addition to providing satellite capacity for private networks, the
Company's services to its business communications customers include customized
end-to-end solutions to their communications needs by providing survey and
analysis of customer needs, network design, engineering and integration,
coordination and filing of permits for access to Solidaridad, importation and
shipping of equipment, complete installation and network testing, systems
operations training and ongoing maintenance and technical support.  ATSI commits
to provide its customers error-free transmission at U.S. performance standards
of 99.98% reliability.  All services are provided by the Company's personnel in
San Antonio, Texas and Mexico.

     ATSI's business communications customers currently using Solidaridad and
the Company's Teleport include: Reuter's de Mexico, S.A. de C.V. for information
distribution between Mexico and the U.S.; Banco del Centro for credit card
authorization/verification between Mexico and the U.S.; Total Systems Services
de

                                       56
<PAGE>
 
Mexico, S.A. de C.V. for credit card authorization services between Mexico and
the U.S.; Operadora Corporativo Miro Reservation Network between Mexico and the
U.S., with a link to Grand Cayman; Rooster Products International between Mexico
and the U.S.; Copamex within Mexico and between Mexico and the U.S.; and Evamex
within Mexico and between Mexico and the U.S.

     Networks using VSATs have been growing rapidly to meet the specialized data
requirements of particular industries, such as banking, mining and retailing.
The Company believes that the VSAT market in Latin America has the potential to
grow significantly in the future, although there can be no assurance that such
growth will occur.

     The Company's private telecommunications network services provide
substantially higher profit margins than its long distance call services.  As a
result, and further due to the anticipated increase in demand for international
satellite services, ATSI intends to continue to engage in aggressive sales and
marketing efforts with respect to this aspect of its business.  ATSI's private
network services generated revenues of approximately $318,000 during the
Company's 1995 fiscal year and revenues of approximately $564,000 during the
first six months of fiscal 1996.  Private network services represented
approximately 6.6% of the Company's total operating revenue during fiscal 1995,
and 11.6% of total revenues during the first six months of fiscal 1996.  The
Company's private network services contracts generally last from two to five
years.  As a result, there exists no seasonal variation in revenues with respect
to private network services.

Carrier Services

     In addition to providing private networks to business customers, ATSI
offers satellite capacity to domestic and regional communications carriers in
Latin America that lack transmission facilities to locations in the U.S. or need
more transmission capacity into the U.S. ATSI began marketing such services to
foreign telecom carriers in the last quarter of fiscal 1995. In the second
quarter of fiscal 1996, the Company entered into an agreement with TELPAN (a
Panamanian telecom carrier) to provide transmission capacity into the U.S. for
U.S. Government traffic out of Panama. Although the Company does not currently
have any additional agreements to provide such carrier services, the Company
believes that this is in part the result of the relative infancy of its efforts
in this area and that, if the regulatory environment permits, significant
opportunities could arise with respect to the provision of satellite
transmission capacity. Therefore, the Company will continue to pursue what it
believes to be opportunities with domestic and regional communications carriers
in this market.

Sales and Marketing

     As of April 30, 1996, the Company employed an international sales manager
and two account executives for sales and marketing of private networks. The
sales manager is based in the U.S., while the account executives are based in
Mexico City, Mexico. However, each spends a significant amount of time working
in either country. The Company's senior management also takes an active role in
supporting the sales team and attracting new accounts for private networks and
carrier services. All of the Company's private network sales personnel are
fluent in both English and Spanish.

     ATSI utilizes several marketing channels. The Company focuses on securing
new business through direct prospecting and sales efforts, as well as from leads
supplied by Telecomm, financing companies specializing in the telecommunications
industry, telecommunications equipment vendors and existing customers.

     The Company locates prospects through information obtained from
institutions such as the American Chamber of Commerce in Mexico and the Mexican
Chamber of Commerce (Concanaco Servytur), as well as from trade periodicals such
as Mexico Business, Twin Plant News, and Latin Trade Magazine. When a prospect
is identified, the Company's sales personnel contact the prospect directly for
qualification. Quotas are set by the sales manager for both prospecting and
sales. Other direct marketing efforts include attendance

                                       57
<PAGE>
 
at or participation in major conventions or expositions for targeted user
groups, as well as maintaining a presence on the Internet relative to satellite
private network and carrier services.  In the near future, ATSI intends to
advertise in specific industry magazines aimed as its target customers, which
include:

          1) U.S. corporations operating in Mexico and Latin America,
          2) Mexican corporations operating in the U.S.,
          3) Mexican fortune 100 companies,
          4) Hotels and resorts in Mexico,
          5) Mexican banks and financial institutions, and
          6) Latin American telecommunications companies.

     Telecomm, the owner and operator of Solidaridad, has executed bilateral
agreements with most of the Latin American countries which allow entities in
those countries to access Solidaridad.  Telecomm frequently receives requests
from Latin American companies requiring private networks or carrier services.
Due to Telecomm's inability to provide end-to-end solutions to these companies,
specifically for network needs between Latin American sites and the U.S., these
requests are sometimes forwarded to ATSI sales personnel.

     The leasing division of IBM de Mexico has utilized ATSI-Mexico as a
network integrator for their customers requiring turn-key domestic (intra-
Mexico) or international (U.S.-Mexico) telecommunication networks. IBM and ATSI
worked in tandem to provide the prospective customers with a complete solution
to include the computer data network, telecommunication network and financing.
IBM has periodically contacted ATSI sales personnel with prospects which they
jointly pursued.

     Although no formal arrangements exists to do so, many of ATSI's vendors
such as Newbridge de Mexico, Red Uno and ISC Bunker Ramo periodically contact
ATSI sales personnel for assistance in providing their customers with turn-key
telecommunication networks. The vendors typically only provide a single
component to the complete network, and must work with a telecommunications
network provider such as ATSI in order to provide complete solutions to their
customers' needs.

     ATSI sales personnel are required to contact existing customers on a
monthly basis in order to ensure that such customers' current needs are being
met. This activity may stimulate sales growth by increasing usage levels among
its current customer base. These existing customers may also provide ATSI sales
personnel with qualified leads for new business.

Competition

     In providing network management services, ATSI competes with MCI/OTI, LDDS
Worldcomm, Telefonos de Mexico, GeoComm/SERSA and others, many of which have
significantly greater resources and more extensive domestic and international
satellite and fiber-optic communications networks than the Company.  The Company
uses the Solidaridad Satellite System combined with fiber-optic networks in
Mexico and the U.S. to meet its customers' requirements.

     For most of the Company's business communications services, the factors
critical to a customer's choice of a service provider are cost, reliability,
ease of use, speed of installation and, in some cases, geography, network size
and hauling capacity.  The Company believes it has the reputation as a
responsive service provider of customized communications services.  ATSI's
Teleport facility, combined with its engineering and operations capability,
provide the Company with considerable flexibility in tailoring cost-effective
communications services to meet its customers' requirements.  This network
allows ATSI to implement communications networks to and from virtually any
location in the U.S. and Latin America.  The Company believes that its
responsiveness is an important factor in a customer's selection of ATSI.  The
Company's size also allows it to provide services more promptly and
conveniently, particularly when a customer's needs require rapid installation of
service or unique solutions.  The Company believes that many markets which are

                                       58
<PAGE>
 
important to ATSI are not large enough for a substantially larger competitor to
focus the resources necessary to provide cost competitive and responsive
service.  In addition, ATSI's understanding of international telecommunications
issues allows it to provide prompt solutions to the diverse communications needs
of multinational corporations, government entities and news organizations.

     The Company believes that it holds certain competitive advantages with
respect to conducting business in Mexico and Latin America. In the U.S., the
current trend by vendors of satellite services is to provide turnkey services
and network management, rather than simply the "up-link" and "down-link"
facilities. ATSI's concept is similar, but is targeted toward the Latin American
market, which has a greater need for total bypass telecommunications services.
Most of the Company's top management are bilingual and bicultural, which the
Company believes is essential to building effective working relationships with
persons and business entities in the Latin American region. Additionally, ATSI-
Mexico provides an array of services to aid ATSI in the provision of domestic
(Mexico) and international private networks. See "-- ATSI-Mexico."

Strategy

     The Company's mission is to become a full service international
telecommunications carrier providing private line, direct dial and other long
distance and value added network services between Latin America and the U.S.
ATSI intends to pursue this strategy from the network management aspect of its
business by, among other things, attracting new private network accounts,
working to increase the usage level of current private network clients,
competing for licenses issued by Latin American countries to provide expanded
network services, including value added network services, where the regulatory
environment permits, pursuing strategic alliances with Latin American telephone
companies and international telecommunications carriers to provide satellite
transmission capacity into the U.S. and reselling excess private-line capacity.
The Company's private telecommunications network services provide substantially
higher profit margins than its long distance call services.  As a result, and
further due to the anticipated increase in demand for international satellite
services, ATSI intends to continue to engage in aggressive sales and marketing
efforts with respect to this aspect of its business.  Additionally, because many
costs of providing network management services are fixed costs of the Company,
ATSI expects that it will realize increased margins as network and carrier usage
expand.  There can be no assurance, however, that the Company will recognize
increased revenues and/or profits from the provision of such network services in
the future.

     The Company's initial focus has been on Mexico, and, because ATSI believes
that the regulatory climate in Mexico will continue to be favorable with respect
to its business, the Company intends to continue to concentrate primarily on
opportunities to provide communications services to, from and within that
country.  In connection with this plan, ATSI anticipates that it will target
U.S. companies with operations in Mexico and Latin America, Mexican and Latin
American companies with operations in the U.S., U.S. and foreign companies
participating in the "in-bond" (maquiladora) manufacturing program and entities
in Mexico and Latin America with existing VSAT networks requiring connectivity
to the U.S.

LONG DISTANCE CALL SERVICES

Operator Service Provider Industry Overview

     In the U.S., the Operator Service Provider ("OSP") industry developed out
of the deregulation of interstate telephone services by the Federal
Communications Commission ("FCC") in 1981, and the court-ordered divestiture in
1984 leading to the break up of AT&T and the formation of the Regional Bell
Operating Companies ("RBOCs"). Prior to 1985, virtually all interexchange
operator services were provided by AT&T. The deregulation of the telephone
industry created a substantial market opportunity for companies competing for
traffic requiring operator-assisted services and long distance processing.
Related judicial rulings permitted private ownership and operation of pay
telephones.

                                       59
<PAGE>
 
     Prior to deregulation, traditional operator services included no-charge
dialing assistance, verification of busy line condition, emergency interrupt and
free information requested by callers enabling them to complete calls.  As
manual assistance costs increased and callers became more familiar with how to
directly dial calls, many of these services were tariffed and charged to
callers.  Currently, "operator services" means providing the systems which route
and complete calls, allowing callers to be billed later from their local
telephone company, and providing alternative methods of charging calls.  OSPs
are entities which process automated or live operator completed calls in a
manner that places the OSP in control of the automated or live operator function
and the billing arrangements.  The OSP industry has brought innovations to the
marketplace, such as multilingual operators, teleconferencing, voice messaging
(e.g. delivering a caller's message later if a line is busy or not answering)
and multiple billing options including the use of major credit cards.

     Away from home, callers are dependent upon the equipment, lines and
carriers that are selected, maintained and paid for by various location owners
or agents ("call aggregators"). Currently, call aggregators in the U.S. and
Mexico, such as hotels, convention centers, hospitals, university dormitories,
institutions and private payphone managers, can choose the long distance
telecommunications company that will complete and process their customer's "0+"
("Zero Plus," automated credit or calling card) and "0-" ("Zero Minus," operator
assisted) calls. Call aggregators contract with OSPs to provide routing and
billing arrangements for these calls and receive commission revenue from OSPs
for the use of their space, equipment and local lines. Transient callers may
have the option of billing the call to a major credit card, calling card, a
third number, or to make a collect call. It is also possible for a caller to
dial carrier access codes, such as 800, 950 or 10XXX, allowing the caller to use
the operator services of other OSPs than the primary presubscribed carrier. The
provision of operator services to call aggregators as a significant source of
revenue is a recent development in the telecommunications industry.

     According to data provided to the FCC, U.S. OSP revenues in 1994 were in
excess of $10 billion.  Although no such information is available with respect
to international OSP revenues, industry revenues in 1994 for international long
distance, of which OSP revenues are a component, in fact grew at a faster rate
than domestic long distance revenues.  Additionally, international long distance
provided revenue and gross profit per minute at a substantially higher rate than
domestic long distance.  The Company believes that as international settlement
rates (which provide the basis for determining the amount of payments owed by
U.S. carriers to foreign carriers for the services U.S. carriers bill and the
amount they are owed for services that foreign carriers bill) and costs for
leased transmission capacity decline, international long distance will continue
to grow at a faster rate and provide higher revenue and gross profit per minute
than domestic long distance.

     As a result, the Company intends to decrease its efforts toward providing
OSP services in the highly competitive U.S. market in the fourth quarter of
fiscal 1996, and increase its focus on the international long distance market,
particularly between the rapidly growing market of Mexico and the U.S., for the
provision of OSP services. U.S.-billed revenues for international long distance
traffic with Mexico increased from approximately $731 million in 1988 to $1.4
billion in 1993, the most recent year for which such information is available.
The significant increase in such traffic, as well as that with other Latin
American countries, is due in part to (i) the ties that exist between many major
metropolitan areas in the U.S. and Mexico and other Latin American countries,
which have been strengthened by the rapid growth of the Hispanic segment of the
U.S. population, and (ii) the increase in trade between Mexico and other Latin
American countries and the U.S.

     Competition between the Company and other operator services providers is
based upon commission programs, quality of service, reporting and customer
service. The Company's revenues from international long distance call services
were $2,952,571 during the Company's 1995 fiscal year (of which 98% was from
traffic between Mexico and the U.S.) and $2,913,515 for the six months ended
January 31, 1996 (of which 87% was from traffic between Mexico and the U.S.),
which accounted for 40% and 39%, respectively, of

                                       60
<PAGE>
 
the Company's minutes of use and 66% and 68%, respectively, of its overall long
distance-related revenues.  However, there can be no assurance that such an
increase in revenues will continue.

Operations and Services

     The Company provides domestic and international long distance call services
through its family of "Plus" plans, as an alternative to those services offered
by AT&T, MCI, Sprint and other call service providers.  See "--Competition."
The Company owns and operates its own switching facility and an operator center
located at its headquarters in San Antonio, Texas (the "Switch").  The Company
provides live and automated operator services 24 hours per day, 365 days per
year, and features multi-lingual operators versed in English, Spanish,
Portuguese and, at times, other languages.  At January 31, 1996, the Company
employed 20 full-time and 12 part-time operators.  The Company maintains a
sophisticated emergency call handling system for calls originating in the U.S.
that enables its operators to access police, fire and other emergency agencies
within the jurisdiction of the telephone from which the call is placed.  The
Company utilizes its own transmission facilities when possible or contracts to
use facilities of other long distance network providers as necessary.

     The Company provides operator-assisted services through its CallPlus(SM)
program for subscribers such as private and public telephones, hotels, motels,
casinos and resorts in the U.S. and Mexico. All long distance telephone calls
originating from a subscriber's property are directed to call destination points
by computerized switching equipment located at the Company's control center. The
digital telecommunications switching equipment is linked to the Company's
operator assistance hardware and software system, which includes a local area
network of computerized operator terminal work stations. Call processing is
either handled automatically by the Company's 0+ systems or routed to an
operator who provides the 0- assistance needed by the call originator. Users of
the Company's services can charge their calls with most Bell calling cards or
commercial credit cards. Additionally, calls handled by an operator can be
person to person, collect or third party calls.

     An automated call requires the use of a touch tone telephone.  This enables
the caller to provide billing information and complete the call without ever
speaking to an operator.  Upon hearing the "bong" tone, the caller enters a
credit card number which can include telephone company calling cards and
commercial credit cards such as Visa, MasterCard and American Express.

     To route a call to a Company operator from a subscriber telephone, a caller
in Mexico and elsewhere generally dials "0," and the area code and number. The
call is then automatically routed to the Switch. In the hospitality industry an
autodialer may be installed at the subscriber's premises. When an autodialer is
used, it monitors the numbers dialed and automatically redirects calls to the
Company. The interception and direction of telephone calls by the autodialer is
transparent to the phone user. As Company operators receive the incoming calls,
they collect billing information from the caller and enter it into the Company's
computer system from their operator terminals. Operators identify themselves as
American Telesource International and Communications Services operators to
persons placing calls from subscriber telephones in the U.S. and Mexico,
respectively. All calling information (including origination, termination and
billing numbers) is recorded for credit validation, rating the call and billing
the end user. The call is then released into the local telephone company's or
long distance carrier's system for completion. The Company selects the most cost
effective and efficient method of completing the call.

     The Company contracts with subscribers to provide operator services for
calls made from telephones they operate or telephones which are located on their
property, offering them the opportunity to receive commissions on calls made on
their phones. Subscribers earn commissions based on the gross billable revenue
originating from the subscriber's property. The commission rate is determined in
accordance with an agreement between the subscriber and the Company, or between
the subscriber and an independent marketing representative used by the Company,
as the case may be.

                                       61
<PAGE>
 
     The Company's revenue is derived from composite charged rates for a call
which is billed to the end-user. Revenue per call is subject to limits imposed
by the Company and regulatory authorities. It is based upon operator assistance
surcharges (if applicable), per minute usage charges between points of origin
and destination, and rates determined in accordance with agreements made with
subscribers.

     Approximately one-fourth of the calls handled by the Company are billed to
commercial credit cards.  The Company utilizes the services of a credit card
processing company for the billing of these calls and receives cash from these
calls, net of transaction and billing fees, within seven days from the dates the
calls are made.  All other calls, including calling card, collect, person-to-
person and third-party billed calls, are billed under an agreement between the
Company and Zero Plus Dialing, Inc. ("ZPDI"), one of the largest billing and
collection clearinghouses in the United States.  This agreement allows ATSI to
submit call detail records to ZPDI, which in turn forwards these records to the
local telephone companies that maintain the addresses of the parties to be
billed for the calls.  The local telephone company includes the call(s) in a
billed party's home telephone bill, collects the funds and remits those funds
net of charges to ZPDI.  ZPDI then remits the funds net of charges to ATSI.
Because this collection process can take up to 75 days, ATSI participates in an
advance funding program offered by ZPDI under which ZPDI purchases 100% of the
call records for 75% of their value within five days of presentment to ZPDI.
The remaining 25% of the call records is remitted to ATSI net of charges as ZPDI
collects the funds from the local telephone companies.  ATSI currently pays ZPDI
a funding charge of prime plus 4% per annum on the 75% of the value of the calls
which is advanced to ATSI.

     The Company is able to transmit long distance telephone calls to all points
in the United States and international destinations serviced by AT&T, MCI and
Sprint. A long distance telephone call generally consists of three segments --
origination, switching and termination. A domestic long distance call originates
on a local exchange network and is transported by a long distance carrier to the
Company's Switch. The call is then carried via the long distance network to
another local exchange network where the call is terminated. An international
long distance call is similar to a domestic long distance call, but typically
involves at least two long distance carriers: a carrier transporting the call
from the country of origination and a carrier terminating the call in the
country of termination.

     At January 31, 1996, the Company provided operator services to 5,693 and
3,627 hotel and motel rooms in the U.S. and Mexico, respectively. The Company's
customers include certain Holiday Inn, Best Western and Ramada Inn franchises
and the casinos of Circus Circus. In addition, at January 31, 1996, the Company
had service contracts with pay telephone owners covering 2,281 and 391 public
telephones in the United States and Mexico, respectively. The Company carried
923,341 and 590,792 minutes of operator services traffic during fiscal 1995
originating in the U.S. and Mexico, respectively, and 930,794 and 428,350
minutes, respectively, for the six months ended January 31, 1996. The Company
carried an average of 155,132 and 71,392 minutes per month of operator services
traffic originating in the U.S. and Mexico, respectively, during the six months
ended January 31, 1996, as compared to 64,936 and 22,685 minutes per month,
respectively, during the six months ended January 31, 1995. The Company's
operator services revenues from calls originating in the U.S. and Mexico
amounted to $1,516,958 and $2,890,891, respectively, in fiscal 1995, and
$1,389,417 and $2,538,280, respectively, for the six months ended January 31,
1996.

     The Company also provides operator-assisted services for Latin American
travelers in the United States through its TravelPlus(SM) and RoamerPlus(SM)
programs. Latin travelers typically do not have AT&T, MCI or Sprint travel
cards, nor do their countries' national phone companies provide them with travel
cards that can be used in the United States. However, such travelers generally
carry common international credit cards, such as Visa, Mastercard and American
Express. TravelPlus(SM) enables Latin travelers to use an eligible common credit
card to place domestic or international calls from virtually any phone in the
United States and reach a Portuguese or Spanish speaking ATSI operator. By using
a credit card as a phone card, the traveler is able to avoid the high cost of
collect calls and minimize hotel and public phone surcharges. Callers using

                                       62
<PAGE>
 
TravelPlus(SM) are billed directly through their credit card companies, and ATSI
is paid in U.S. dollars. ATSI has contracted to provide TravelPlus(SM) services
to the Bank of Brazil for its Visa card holders.

     RoamerPlus(SM) enables Latin American travelers to use their cellular
phones while in the United States. Because of problems associated with cellular
phone fraud, United States cellular companies generally limit foreign cellular
users while traveling in the United States from placing international calls. To
avoid this problem, PIN numbers are issued to Latin Americans through their own
local cellular provider. When in the United States, the Latin American cellular
user dials a special "800" number which connects the user with an ATSI operator
and provides the operator with an account and PIN number. The operator then
completes the call, and charges are billed to the user's local cellular account.
Currently, ATSI has one agreement with a Mexican cellular company to route calls
placed by such company's customers travelling in the U.S. to ATSI's call center.
The service includes collect, calling card and credit card billed calls. As
relationships with other Latin American cellular companies are established, ATSI
anticipates expanding access to this service.

     The Company's telephone services are available 24 hours a day, 365 days per
year.  To assist subscribers and end users with service or billing questions,
the Company maintains a customer service department and staff which is available
during normal business hours.  Emergency 24-hour service is available to all
subscribers.  Seasonal variation in call volume is expected by the Company from
hospitality and payphone subscribers, reflecting the higher occupancy rates
during the winter vacation months in Mexico (when U.S. volume is at its lowest)
and lower rates during summer months in Mexico (when U.S. volume is at its
peak).

     The Company's long distance call services business generated revenues of
$4,469,529 during the Company's 1995 fiscal year and revenues of $4,302,932
during the first six months of fiscal 1996.  Long distance call services
represented approximately 93.4% of the Company's total operating revenue during
fiscal 1995, and 88.4% of total revenues during the first six months of fiscal
1996.

     In April 1996, the Company and Long Distance Exchange Corporation ("LDEC")
entered into a litigation settlement agreement with Capital Network Systems,
Inc. ("CNSI") and Teleplus, Inc. ("Teleplus") pursuant to which the parties
agreed not to contract with, provide service to, benefit from, derive revenues
from or solicit any customer of another party with respect to operator-assisted
long distance services from Mexico for a period of 10 months.  Additionally,
CNSI and Teleplus, on the one hand, and the Company and LDEC, on the other hand,
agreed to submit to binding arbitration to resolve any disputes between them for
a period of 22 months.

Switching and Operator Equipment

     The Company's operator center platform consists of a fully redundant
digital Summa Four Switch interlinked with a Digital Equipment Corporation VAX
4000, which utilizes Micro Dimensions software to interconnect the computerized
operator terminal work stations at the service center. The operator center
platform enables the Company to process calling card calls, collect calls,
person-to-person, third-party and credit card calls. ATSI is currently in the
process of turning up a NACT LCX 120 switch, which will enhance its current
platform by allowing the Company to process debit cards, one-plus calls, as well
as offer inmate facility automated call processing and 800 service. The Company
expects that the LCX 120, which is scheduled to go on-line in the fourth quarter
of fiscal 1996, will enable the Company to provide a full array of call
services.

Sales and Marketing

     The Company markets its long distance call services in the United States
and in Mexico through the combined effort of three direct sales representatives
based in its corporate offices, two of whom are fluent in both English and
Spanish, and a network of independent marketing representatives. The Company's
corporate sales force focuses on larger accounts, such as hotel management
companies, multi-unit franchises and large

                                       63
<PAGE>
 
pay telephone companies.  The Company's independent representatives in the
United States and Mexico market the Company's operator services in their
respective countries and typically receive a commission based upon the volume of
business generated.  The Company also participates in various industry trade
shows and promotes its call services through advertisements in trade magazines.
The Company customizes its telecommunications services to provide individualized
reports and to achieve, for a given customer, the desired balance between high
customer commissions and low charges to the billed party.

     The OSP industry has primarily provided its services to call aggregators
rather than the general public, allowing subscribers to receive revenues from
calls made from telephones they operate or which are located on their property.
Reasons for selecting call aggregators over residential customers include the
sales volume offered by call aggregators and the high advertising costs and
customer turnover associated with handling residential customers.

     The Company's customers look for operator assistance services as an
additional source of revenue. Although needs vary from market to market, the
Company generally modifies the in-house phone system of subscribers, or installs
additional equipment necessary to interface with the Company's Switch. The
Company contracts with subscribers to provide operator services for calls made
from telephones they operate or telephones which are located on their property,
offering them the opportunity to receive commissions on calls made on their
phones.

Competition

     The overall domestic long distance call services market is dominated by
AT&T. The Company also competes with other public and private companies, such as
Sprint and MCI, which provide long distance call services similar to those of
the Company. These long distance carriers have been in business longer than the
Company and have far greater resources, experience and reputations than the
Company. Moreover, the RBOCs are likely to become major competitors in the long
distance market for both 0+ and 1+ calls as a result of the recently passed
Telecommunications Act of 1996, which permits the RBOCs to immediately provide
long distance service outside their local exchange region. See "--Regulation-
Federal." The Company competes in the international long distance call services
market with AT&T, Sprint, MCI, CNSI and others, many of which, again, have
considerably greater financial and other resources than the Company.

     The Company believes it competes favorably in its targeted markets due in
part to its bilingual operators and billing services and a broad array of
service offerings. Among them, the Company provides its customers with
customized, detailed and sophisticated reporting of calling patterns and volumes
from each customer location. This allows the Company's operator services
customers to analyze their traffic and maximize telecommunication revenues by,
for example, relocating underutilized telephones. The Company's detailed
reporting also allows its customers to reconcile the accuracy or integrity of
their commissions. The Company employs a highly skilled professional staff of
customer service employees and technicians, who provide service 24 hours per
day, 365 days per year.

Strategy

     The Company's mission is to become a full service international
telecommunications carrier providing private line, direct dial and other long
distance and value added network services between Latin America and the U.S.
ATSI intends to pursue this strategy in its long distance call services business
by, among other things, competing for licenses issued by Latin American
countries where the regulatory environment permits, to provide expanded long
distance call services, working to increase the volume of calls which it
processes by attracting new call services accounts and creating billing
innovations such as using credit cards as calling cards, as the Company has done
with respect to its TravelPlus(SM) program. Because margins on international OSP
calls are substantially higher than domestic (U.S.) OSP calls, and because the
Company expects growth to continue in the market for calls between the U.S. and
Mexico, as well as other Latin American countries,

                                       64
<PAGE>
 
the Company intends to focus on the international long distance market,
particularly between Mexico and the U.S., for the provision of long distance
call services.  ATSI intends to decrease its efforts toward providing OSP
services in the highly competitive U.S. market in the third quarter of fiscal
1996, after which time the Company anticipates that it will offer such services
domestically on a "demand type" basis only.

     The Company currently views the following target markets as ones in which
it can most profitably provide its service for the optimum benefit of the
customer:

     .    International Public Communications -- Includes segments such as
          private and public phone operators, cellular telephone operators and
          transportation centers such as airports, ship ports and marinas,
          primarily in Mexico.

     .    International Hospitality Industry -- Includes hotels, motels and
          resorts located primarily in Mexico.

     In addition, ATSI intends to promote its TravelPlus(SM) program to credit
card issuers in Latin American countries where and as the regulatory environment
permits. With respect to its RoamerPlus(SM) program, ATSI has initiated
discussions with certain Mexican cellular companies to route calls placed by
U.S. citizens in Mexico to the Company's call center. If successful in these
negotiations, ATSI expects to expand RoamerPlus(SM) services to enable U.S.
citizens to use their cellular phones while travelling in Mexico.

ATSI-MEXICO

     American Telesource International de Mexico, S.A. de C.V. was formed on
June 20, 1995 to aid ATSI in the provision of domestic (Mexico) and
international long distance services and private networks. At the direction of
the Company, ATSI-Mexico provides an array of services to support ATSI clients,
including frequency applications, as well as planning, design, implementation
and maintenance of satellite networks. ATSI-Mexico also provides intra-Mexico
satellite network services, utilizing ATSI's engineering team for the design of
such systems. For networks requiring U.S. connectivity, the San Antonio Teleport
is utilized. ATSI-Mexico technical personnel are trained by the Company's
technical staff in areas such as monitoring, diagnostics, and troubleshooting of
satellite channels.

     ATSI-Mexico is 49% owned by ATSI and 51% owned by a Mexican citizen.
Mexican law mandates that any company participating in public communications
within Mexico be majority owned by a Mexican entity. However, ATSI maintains
significant control over the operations of ATSI-Mexico and has limited the
authority of the other shareholder to sell or transfer his shares.

     ATSI intends to focus primarily on the Mexican market for the provision of
international long distance call services.  The Company believes that
significant opportunities to provide call services within Mexico and between
Mexico and the U.S. will arise from the law written into effect in June 1995 by
the Secretaria de Communicaciones y Transportes ("SCT"), which provides for the
methods by which companies can apply for concessions and licenses to establish
and operate telecommunications services businesses within Mexico.  This law is,
effectively, the first step in the deregulation of the telephone industry within
Mexico.  It also formalizes the methods by which companies such as ATSI may
compete against Telefonos de Mexico (Telmex), the privately owned
telecommunications monopoly in Mexico.

     The Company, through ATSI-Mexico, has applied or intends to apply to the
SCT for the following licenses, which, if obtained, the Company believes will
enable it to expand significantly its business in Mexico. However, there can be
no assurance that such licenses will be obtained, and, if obtained, that such
licenses will enable the Company to expand operations or increase revenue in
Mexico:

     .    Public Phone License (applied for) -- to install public pay phones in
          Mexico, from which ATSI could provide both local call service and
          domestic and international long distance service. The Company

                                       65
<PAGE>
 
          has received formal confirmation from the SCT that it will be granted
          such a license as soon as certain regulations are published by the
          SCT. The Company expects to receive such license during the fourth
          quarter of fiscal 1996. The Company believes that the receipt of this
          license will create opportunities to expand its long distance call
          services operations and increase revenues in Mexico, and is
          considering all options with respect to the license, including
          possible strategic alliances and partnerships.

     .    Comercializadora License (applied for) -- to provide long distance and
          private line services via TELMEX's or any other concessionaire's fiber
          optic infrastructure and resell the existing fiber infrastructure in
          Mexico for various communications services, including the provision of
          "1+" long distance service to its existing hotel and commercial
          clients. Receipt of a Comercializadora license would enable ATSI to
          offer to its existing clients and market to potential customers a
          complete package of long distance services, including private
          networks, 0+, 0- and 1+ capabilities, as well as direct billing
          services, which, the Company believes, could have a positive effect on
          its revenues due to the desire of customers to consolidate the
          provision of their communications services into a single provider. The
          Company anticipates receiving approval for this license during the
          fourth quarter of fiscal 1996.

     .    Shared Teleport License (to be applied for) -- to build a shared
          teleport facility and qualify as a shared teleport facility operator
          to provide communications transport capabilities for ATSI's Mexican
          clients, as well as other non-shared teleport-based carriers and their
          clients. A shared teleport facility would enable the Company to reduce
          costs for the provision of private networks with a link in Mexico by
          utilizing a centralized satellite facility (linked to the Mexican
          Solidaridad Satellite System) with which private network subscribers
          could connect through local fiber, thereby eliminating the need for a
          VSAT on every user's premises. The Company anticipates applying for
          this license in the fourth quarter of fiscal 1996.

     In the third quarter of fiscal 1996, ATSI-Mexico obtained a Value-Added
Service License to provide a value added network service, delivering public
access (as distinct from current private network access) to the Internet,
including E-Mail, Local Area Network interconnection and frame relay services.
The Company will continue to apply for government-issued licenses which the
Company believes will create opportunities to expand operations in Mexico and
achieve its goal of becoming a full service telecommunications carrier.

     ATSI believes that its affiliation with and interest in ATSI-Mexico gives
it a competitive advantage over other U.S. telecommunications companies
attempting to enter the Mexican market. All of ATSI-Mexico's significant
employees are Mexican citizens with substantial experience in the Mexican
telecommunications industry and solid working relationships with persons and
entities in Mexico connected with such industry. The Company believes that its
success to date in Mexico has been largely the result of, and that its future
success with respect to Mexican telecommunications licenses applied for and
implementation of business strategies in Mexico will be dependent upon, such
individuals' hard work and ability to continue to understand and develop
relationships within the Mexican telecommunications industry.

ATSI'S INTERNATIONAL TELEPORT AND NETWORK CONTROL CENTER

     The Company has constructed an international teleport/satellite earth
station at its headquarters in San Antonio, Texas to serve as a
telecommunications gateway to the United States. ATSI believes that the Teleport
is one of the first facilities in the South Central United States specifically
designed to provide international telecommunications networks between the United
States and Latin America via the Mexican Solidaridad Satellite System. The
Teleport provides fiber optic integration into U.S. based private and public
telecommunications networks via a fiber optic link to a facility in downtown San
Antonio, where all major long distance carriers have a point of presence. The
Company constructed the Teleport utilizing advanced digital satellite
communications equipment, and built the network operating system modularly to
enable it to

                                       66
<PAGE>
 
expand telecommunications capacity quickly, on an as-needed basis.  In September
1995, the Company increased the system's networks capacity from 20 watts to 400
watts, giving ATSI the capability to operate up to 30 T-1 circuits, or 720 64K
circuits of C-band frequency and 144 64K circuits of Ku band frequency.

     ATSI's Teleport facility contains a 6.1 meter "C" and a 6.1 meter "Ku" band
earth station with fully redundant electronics capable of "seeing" across the
full 500 Mhz of these two satellite bands in both horizontal and vertical
polarization schemes.  The earth station electronics are state-of-the-art in
design and dependability.

     The Company's Network Control Center (the "Control Center"), also located
at its San Antonio headquarters, houses the converter subsystem relative to the
networks, the modem subsystem and the data equipment. The Control Center serves
as the maintenance and control hub of the Company's private networks and long
distance call services systems. It utilizes specialized software and hardware
components to monitor subsystem elements within the Teleport. Remote VSATs are
equipped with maintenance and control processors that monitor subsystem elements
and dial into the Teleport facility to report fault conditions. The Control
Center technicians, once aware of a problem, can dial into the remote terminals
to diagnose, troubleshoot, make equipment changes or upgrade for complete system
management. The Company's Control Center is protected through an uninterruptable
power supply system which, upon commercial power failure, utilizes battery back-
up until an on-site natural gas generator is automatically triggered to supply
AC power. The Control Center facility has a dedicated environmental control
system to maintain optimal conditions of 68(degrees) F with light-to-moderate
levels of humidity.

REGULATION

     The Company's business operations are subject to extensive federal and
state regulation, and more limited foreign regulation. Federal laws and U.S.
Federal Communications Commission ("FCC") regulations apply to interstate
telecommunications (including international telecommunications that originate or
terminate in the United States), while particular state regulatory authorities
have jurisdiction over telecommunications originating and terminating within the
state. The laws of other countries only apply to carriers doing business in
those countries. Thus, if the Company conducts business with such countries
through settlement agreements with a foreign carrier, or otherwise by engaging
in service to such countries, it is affected indirectly by such laws insofar as
they affect the foreign carrier. There can be no assurance that future
regulatory, judicial, and legislative changes or activities will not have a
material adverse effect on the Company, that domestic or international
regulators or third parties will not raise material issues with regard to the
Company's compliance or noncompliance with applicable regulations, or that
regulatory activities will not have a material adverse effect on the Company.

     In addition, changes in certain regulations may potentially preclude or
impair the Company's ability to provide operator services in certain
jurisdictions. The Company does not foresee any such changes; however, it cannot
predict whether such changes may occur. Therefore, the Company cannot estimate
the impact of such changes upon its operator services in the event of any such
change.

     FEDERAL.

     The FCC has classified the Company as a non-dominant, interexchange
carrier. Generally, the FCC has chosen not to exercise its statutory power to
closely regulate the charges, practices, or classifications of non-dominant
carriers. Nevertheless, the FCC acts upon complaints against such carriers for
failure to comply with statutory obligations or with the FCC's rules,
regulations, and policies. The FCC also has the power to impose more stringent
regulatory requirements on the Company and to change the Company's regulatory
classification. In the current regulatory atmosphere, the Company believes that
the FCC is unlikely to do so.

     Among domestic carriers, only the local exchange carriers ("LECs") are
currently classified as dominant carriers.  Thus, the FCC regulates many of the
LECs' rates, charges, and services to a greater degree than those of the
Company.  Until October 1995, AT&T was classified as a dominant carrier, but
AT&T successfully petitioned the FCC for non-dominant status in the domestic
interstate and interexchange marketplaces.  Therefore, certain pricing
restrictions that once applied to AT&T have been eliminated, likely making
AT&T's prices more competitive with those of the Company.  Recently, AT&T was
also reclassified as a non-dominant carrier for international services.

     The Company has the authority to provide domestic, interstate
telecommunications services.  The Company also has been granted authority by the
FCC to provide switched international telecommunications services through the
resale of switched services of United States facilities-based carriers and to
provide certain international telecommunications services by acquiring circuits
on various undersea cables or leasing certain satellite facilities. The FCC
reserves the right to condition, modify, or remake such domestic and
international authority for violations of the Communications Act of 1934, as
amended (the "Communications Act") or the FCC's regulations, rules, or policies
promulgated thereunder.  Although the Company believes the possibility to be
remote, a rescission by the FCC of the Company's domestic or international
authority or a refusal by the FCC to grant additional domestic or international
authority would have a material adverse effect on the Company.

     Currently, the FCC requires that domestic and international non-dominant
carriers must maintain interstate and international tariffs on file with the
FCC.  The Company believes it is in full compliance with all applicable FCC
tariff regulations.  Prior to a recent court decision, Southwestern Bell v. FCC,
43 F.3d 1515 (D.C. Cir. 1995), domestic non-dominant carriers were permitted by
the FCC to file tariffs with a "reasonable range of rates" instead of detailed
schedules of individual charges.  However, the Company must now file tariffs
containing specific rates.  In reliance on the FCC's past relaxed tariff filing
requirements for non-dominant domestic carriers, the Company and most of its
competitors did not maintain such rates for domestic offerings in their tariffs.
Until the two-year statute of limitations expires, the Company could be held
liable for damages for its past failure to file tariffs containing specific
rates.  The Company believes that such an outcome is remote especially in light
of the FCC's recent proposal to adopt a mandatory detariffing policy for
domestic services of non-dominant, interexchange carriers.  Moreover, such an
outcome would not have a material adverse effect on the Company's financial
condition or results of operation.  The Company has always been required to
include detailed rate schedules in its international tariffs.

     As a non-dominant carrier, the Company is also subject to a variety of
miscellaneous regulations that, among other things, govern the documentation and
verifications necessary to change a consumer's long distance carrier, limit the
use of "800" numbers, require certain disclosures regarding operator services,
limit foreign ownership and control, and require prior approval of transfers of
control.  The Company began providing operator services in the U.S. in May 1994.
The FCC requires the filing of informational tariffs concerning such services
and requires both written and verbal identification of the operator service
provider on each call processed.

     To date, the FCC has only exercised its regulatory authority to supervise
closely the rates of dominant carriers.  However, the FCC has increasingly
relaxed its control in this area.  As an example, the FCC is considering
repricing local transport charges (the fee for the use of the LECs' transmission
facilities connecting the LECs' central offices and the interexchange carrier's
access point).  In addition, the LECs have been afforded a degree of pricing
flexibility in setting access charges where adequate competition exists, and the
FCC is considering certain proposals to relax further LEC access regulation.
The impact of such repricing and pricing flexibility on facilities-based
interexchange carriers, such as the Company, cannot be determined at this time.

     The Telecommunications Act of 1996 (signed into law on February 8, 1996)
permits the RBOCs to immediately provide interLATA interexchange (long distance)
services outside their local exchange region.

                                       68
<PAGE>
 
Moreover, the Act allows the RBOCs to provide long distance services in-region
with FCC approval after the FCC has consulted with the Department of Justice and
determines that such market entry is consistent with the public interest,
convenience, and necessity.  In order for a RBOC to provide in-region interLATA
interexchange service, it must also demonstrate that it has a facilities-based
competitor and that it has complied with a 14-point competitive checklist as
determined by the Commission.  As a result, the Company will undoubtedly face
increased competition from the RBOCs.  This new law attempts to guard against
anti competitive conduct that could result from an RBOC having access to all
customers on its existing networks as well as its ability to cross-subsidize its
services and discriminate in its favor against its competitors.

     The FCC has determined that call-back services using uncompleted call
signaling violates neither United States domestic nor international law.  Call-
back services involve calls originating in a foreign country directed in such a
manner as to give the foreign caller the advantage of the lower charges for
outbound United States calls.  However, United States call-back providers are
not authorized to provide service to customers in countries that expressly have
declared such call-back services to be illegal.  The FCC will receive
documentation from any government that seeks to place United States carriers on
notice that call-back services using uncompleted call signaling has been
expressly declared illegal in its country.  Currently, the Company does not
itself provide call-back services and it does not provide services to resellers
and other carriers that do provide such call-back services.

     The microwave and satellite communications licenses held by the Company are
subject to FCC regulations.  Such licenses were granted for fixed terms with an
option to renew.  The majority of these licenses expire within six years and the
remainder will expire within ten years.  The Company intends to seek renewal of
its licenses and anticipates that they will be renewed in the ordinary course.
Failure to obtain renewal of its licenses could have a material adverse effect
on the Company.

     Except with respect to transit agreements, authorizations held under
Section 214 of the Communications Act (such as those held by the Company) for
international services are limited to providing services or using facilities
between the United States and countries specified in the authorizations. The
Company holds all necessary Section 214 authorizations for conducting its
present business, but may need additional authority in the future. Additionally,
carriers may not lease lines between the United States and an international
point for the purpose of offering switched services without first determining
that the foreign country affords opportunities to United States carriers
equivalent to those available under United States law.

     The FCC also has promulgated certain rules governing the offering of
international switched telecommunications services.  Such calls typically
involve a bilateral, correspondent relationship between a carrier in the United
States and a carrier in the foreign country.  Until recently, the United States
was one of a few countries to allow multiple carriers to handle international
calls; almost all foreign countries authorized only a single carrier, often a
state owned monopoly, to provide telecommunications services.  In light of the
disparate bargaining positions of the United Stated carriers, the FCC imposed
certain requirements to try to minimize the opportunities that dominant foreign
telecommunications providers would have to counterpoise one United States
carrier against another.  These policies include the International Settlement
Policy, which requires that rates of all carriers be uniform on parallel routes
and that traffic received by a United States carrier from a foreign carrier must
be proportional to the traffic the United States carrier terminates to a foreign
carrier.  The Company currently has no agreements with foreign carriers
providing for the handling of switched calls.

     For more than six years, the FCC has been considering the implementation of
a system whereby a caller could make a long distance call from any publicly
available telephone and have the call automatically routed over the long
distance telephone network of the caller's choice. The concept, called Billed
Party Preference ("BPP"), would necessitate that each local telephone company
have access to a data base that could match every U.S. calling card and
telephone number to a preferred long distance company and be able to route each
long distance call accordingly. Implementation of BPP or a similar system could
potentially have a major

                                       69
<PAGE>
 
impact on U.S. operator services companies such as ATSI that depend on
telephones presubscribed, or routed, directly to their network.  Although the
FCC continues to consider the adoption of BPP, it is not likely to be
operational in the near term.  Moreover, less than 33% of the Company's revenues
were generated from such calls during the year ended July 31, 1995, and this
percentage is expected to decease in the future as the volume of international
calls continues to increase.  The Company cannot predict when and if any final
ruling will be issued by the FCC relating to BPP, but the Company does not
expect any ruling on BPP to be implemented in the near future.  See "Notes to
Consolidated Financial Statements--Note 15."

     STATE.

     The intrastate, long distance telecommunications operations of the Company
are also subject to various state laws, regulations, rules, and policies.
Currently, the Company is certified and tariffed to provide service in 23
states. Additionally, the Company provides service in certain states that do not
require certification or registration of any type. Many state regulatory bodies,
however, require the filing of informational tariffs concerning operator
services and require written and/or verbal identification of the operator
service provider on each call processed. The Company is currently in the process
of making the appropriate filings for these informational tariffs in order to
maintain compliance with these jurisdictional requirements. Ultimately, the
Company intends to obtain authorization in all states that require certification
or registration. The vast majority of states require the Company to apply for
certification to provide telecommunications services before commencing
intrastate service and to file and maintain detailed tariffs listing the rates
for intrastate service. Many states also impose various reporting requirements
and require prior approval for all transfers of control of certified carriers,
assignments of carrier assets, carrier stock offerings, and the incurrence by
carriers of certain debt obligations. In some states, prior regulatory approval
may be required for acquisitions of telecommunications operations.

     FOREIGN.

     On June 7, 1995, the SCT, the entity responsible for governing
telecommunications services in Mexico, wrote into law the method by which
companies could apply for concessions and licenses to establish and operate
telecommunications services businesses in Mexico.  This was, effectively, the
first step in the deregulation of the telephone industry in Mexico.  The SCT
also formalized the methods by which companies such as ATSI may compete against
Telmex, the privately owned telecommunications monopoly in Mexico.  The Company,
through ATSI-Mexico, has applied for several licenses to provide various
telecommunications services in Mexico.  The Company hopes to receive various
such concessions and licenses during fiscal 1996, and believes that the receipt
of such concessions and licenses will enable the Company to expand significantly
its call services business in Mexico.

     The Company provides international services by either reselling the
services of other carriers or by entering into direct operating or transit
agreements with PTTs. Generally, PTTs are state-owned and operated monopolies.
Although the services currently provided by the Company are not directly subject
to the laws of other countries, the foreign carriers with whom the Company
conducts business are subject to those laws. Consequently, any changes to the
laws of a country served by the Company could have a material adverse effect on
the Company.

EMPLOYEES

     At April 30, 1996, the Company had 47 full-time employees, of whom 19 are
operators, 5 are sales and marketing personnel and 23 perform administrative
functions, and 20 part-time employees, of whom all are operators.  The Company
believes its future success will depend on its continued ability to attract and
retain highly skilled and qualified employees.  The Company considers its
employee relations to be good.  None of the Company's employees is represented
by unions.

                                       70

PROPERTIES

     The Company's executive offices, Teleport and Control Center are located in
and on the premises of a leased facility in San Antonio, Texas, consisting of
6,350 square feet.  The lease agreement covering such property is effective
until April 1999, and requires the Company to pay rent in the amount of $39,757
per year.  The Company expects to exercise its option to expand into
approximately 5,000 square feet of adjacent office space during 1996.

     The Company's offices in Mexico City are located on the premises of a
leased facility near the World Trade Center, consisting of approximately 2,150
square feet. The lease agreement covering such property is effective until
August 1997, and requires the Company to pay rent in the amount of approximately
$19,200 per year, measured at 7.5 Pesos to one U.S. Dollar.

LEGAL PROCEEDINGS

     There are no material pending legal proceedings to which the Company or any
of its subsidiaries is a party or of which any of their property is the subject.

                                   MANAGEMENT

EXECUTIVE OFFICERS AND DIRECTORS

     The ATSI Board currently consists of three members, Messrs. Smith, Nye and
Moses.  Upon Domestication, the ATSI Board will be increased to five members and
will be divided into three classes, one class of which is to be elected each
year to hold office for a three-year term and until successors are elected and
qualified, as provided by the terms of the Certificate of Incorporation to be
filed pursuant to the Company's Domestication into Delaware.  The terms of the
initial Class A, Class B and Class C directors of the Company will expire at the
1997, 1998 and 1999 annual meetings, respectively.  It is anticipated that
immediately following the Domestication, John R. Moses will resign as a director
of ATSI and Arthur L. Smith and Murray R. Nye, representing a majority of the
directors then in office, will elect, in order to fill such vacancies and newly
created directorships on the Board of ATSI, then a Delaware corporation, Terry
Colbert and Tomas Revesz to serve as the Class B directors and Arthur L. Smith
and Murray R. Nye to serve as the Class C directors.  Messrs. Smith and Nye also
intend to appoint a fifth director immediately following the Domestication to
serve as the Class A director, and, along with Mr. Moses, are currently in the
process of interviewing qualified candidates.  Additionally, immediately
following the Domestication the officers of ATSI will be as follows:  Arthur L.
Smith - President and Chief Executive Officer; H. Douglas Saathoff -Secretary,
Treasurer and Chief Financial Officer; Craig K. Clement - Vice President; and
Everett Waller -Vice President.

     The ATSI Merger Corp. Board of Directors currently consists of four
members, two of whom are Class B directors and two of whom are Class C
directors. The Board of Directors intends to appoint a fifth director to serve
in the position of Class A director, and is currently in the process of
interviewing qualified candidates. Like the ATSI Board upon Domestication, one
of the three classes of ATSI Merger Corp. directors is to be elected each year
to hold office for a three-year term and until successors are elected and
qualified. The terms of the initial Class A, Class B and Class C directors of
the Company will expire at the 1997, 1998 and 1999 annual meetings,
respectively. Terry Colbert and Tomas Revesz will serve as Class B directors and
Arthur L. Smith and Murray R. Nye as Class C directors. Successors to those
directors whose terms have expired are required to be elected by stockholder
vote while vacancies in unexpired terms and any additional positions created by
board action are filled by action of the existing Board of Directors.
Additionally, Arthur L. Smith has been elected to the offices of President and
Chief Executive Officer of ATSI Merger Corp., H. Douglas Saathoff has been
elected to the offices of Secretary, Treasurer and Chief Financial Officer of
ATSI Merger Corp., and Craig K. Clement and Everett Waller have each been
elected a Vice President of ATSI Merger Corp., all to serve in such capacities
until the next annual meeting of the Board of Directors, or until their
respective successors have been duly elected and have been qualified, or until
their earlier death, resignation, disqualification or removal from office. There
is no family relationship among any of the directors and executive officers of
the Company or ATSI Merger Corp. The persons who are directors and executive
officers of ATSI Merger Corp. immediately prior to the Merger will continue to
be the directors and executive officers of the surviving corporation immediately
following the Merger. The following table sets forth the names, ages and
positions of the directors and executive officers of ATSI (following the
completion of the Domestication) and ATSI Merger Corp.:

Operating Officer
</TABLE>

____________
(1) Mr. Smith currently serves as President and Chief Executive Officer of ATSI-
    Texas, the wholly-owned subsidiary of ATSI, through which all of the
    business of ATSI is conducted.
(2) The figure given reflects payment beginning in December 1993 (inception)
    through July 31, 1994.
(3) Mr. Smith receives personal benefits in addition to salary; however, the
    Company has concluded that the aggregate amounts of such personal benefits
    do not exceed the lesser of $50,000 or 10% of Mr. Smith's annual salary and
    bonus.


EMPLOYMENT AGREEMENTS

     It is anticipated that immediately following the Domestication, ATSI will
enter into employment agreements with each of Messrs. Smith, Saathoff, Clement
and Waller, pursuant to which Mr. Smith will agree to serve as President and
Chief Executive Officer of the Company, Mr. Saathoff will agree to serve as
Secretary, Treasurer and Chief Financial Officer of the Company, Mr. Clement
will agree to serve as Vice President of the Company and Mr. Waller will
agree to serve as Vice President of the Company, each for a period of three
years (with automatic one-year extensions unless either the executive or Company
gives 120 days prior written notice of their intent not to renew), unless
earlier terminated in accordance with the terms of the respective agreements.
The annual base salary under such agreements for each of Messrs. Smith,
Saathoff, Clement and Waller is reviewed from time to time, but may not be less
than $80,000, $75,000, $90,000 and $82,500, respectively, per annum.  In
addition, each of Messrs. Smith, Saathoff, Clement and Waller is eligible to
receive bonus payments in amounts to be determined by the Board of Directors
from time to time.  Such bonus payments, however, may not exceed 50% of the
executive's base salary in any fiscal year.

     Pursuant to each of Messrs. Smith's, Saathoff's, Clement's and Waller's
employment agreement, in the event of the executive's death during the term of
his agreement, the Company is required to pay to the executive's estate the base
salary at the rate in effect on the date of death for a period of six months.
In the event of the executive's disability, the Company is required to pay the
executive the base salary at the rate then in effect until the earliest of (i)
the conclusion of the then current term of executive's agreement or (ii) for a
period of six months.  If the Company terminates the executive's employment
agreement without "cause" (as defined therein), the Company is required to pay
the executive his base salary at the rate then in effect until the third
anniversary of the effective date or until twelve months after the date of
termination, whichever period is longer.  If the executive is terminated for
cause, the Company has no further obligations under the agreement.  Should the
executive terminate his employment for "good reason" (as defined therein), the
Company is required to continue to pay the executive the base salary then in
effect until the third anniversary of the effective date or, in the event the
agreement has been automatically extended, until the next anniversary of the
effective date.

     Each of the employment agreements also provides that the executive will not
interfere with the relationship of the Company and any employee, agent or
representative and the executive will not divert or attempt to divert from the
Company any business which provides telecommunications services from the United
States or Latin America until the third anniversary of the effective date or, in
the event the agreement has been

                                       75
<PAGE>
 
automatically extended, until the next anniversary of the effective date, or
until twelve months after the date of termination of executive, whichever period
is longer.  Pursuant to the terms of each of the employment agreements, each
executive will also agree that during the term he performs services for the
Company and for a period of 36 months after termination thereof he will not
directly or indirectly own, manage, operate, control, be employed by,
participate in, or be connected in any manner with the ownership, management,
operation, or control of any business or enterprise which provides
telecommunications services in the United States or Latin America.

1996 OPTION PLAN

     In June 1996, the Board of Directors unanimously adopted the American
Telesource International Inc. 1996 Stock Option Plan (the "1996 Option Plan")
and directed that the 1996 Option Plan be submitted to the shareholders for
their approval.  For a summary of the 1996 Option Plan, see "The 1996 Option
Plan--Summary of the 1996 Option Plan."

EXCULPATORY CHARTER PROVISION

     Each ATSI Company has included in its Delaware Certificate of Incorporation
provisions to eliminate the personal liability of its directors for monetary
damages resulting from breaches of their fiduciary duty; provided, however, that
such provisions do not eliminate liability for breaches of the duty of loyalty;
acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, violations under Section 174 of the DGCL concerning
the unlawful payment of dividends or stock redemptions or repurchases or for any
transactions from which the director derived an improper personal benefit.

     Additionally, each ATSI Company has included in its Delaware Certificate of
Incorporation provisions to indemnify each director and officer of each such
Company who may be indemnified, to the fullest extent permitted by Section 145
of the Delaware General Corporation Law ("Section 145"), as it may be amended
from time to time, in each and every situation where such ATSI Company is
obligated to make such indemnification pursuant to Section 145.  In addition,
each ATSI Company will indemnify each of its directors and officers in each and
every situation where, under Section 145, such ATSI Company is not obligated,
but is permitted or empowered, to make such indemnification.  Each ATSI Company
may, in the sole discretion of the Board, indemnify any other person who may be
indemnified pursuant to Section 145 to the extent the Board deems advisable, as
permitted by such section.  Each ATSI Company will promptly make or cause to be
made any determination which Section 145 requires.  Each ATSI Company believes
that these provisions are necessary to attract and retain qualified persons as
directors and officers.

     Each ATSI Company has entered into or intends to enter into indemnification
agreements with each of its directors and its executive officers.  The
indemnification agreements provide that the Company shall indemnify these
individuals against certain liabilities (including settlements) and expenses
actually and reasonably incurred by them in connection with any threatened or
pending legal action, proceeding or investigation (other than actions brought by
or in the right of the Company) to which any of them is, or is threatened to be,
made a party by reason of their status as a director, officer or agent of the
Company, provided that such individual acted in good faith and in a manner he or
she reasonably believed to be in or not opposed to the best interests of the
Company, and with respect to any criminal proceedings, had no reasonable cause
to believe his or her conduct was unlawful.  With respect to any action brought
by or in the right of the Company, such individuals may also be indemnified, to
the extent not prohibited by applicable laws or as determined by a court of
competent jurisdiction, against expenses actually and reasonably incurred by
them in connection with such action if they acted in good faith and in a manner
they reasonably believed to be in or not opposed to the best interests of the
Company.  The agreements also require indemnification of such individuals for
all reasonable expenses incurred in connection with the successful defense of
any action or claim and provide for partial indemnification in the case of any
partially successful defense.

                              CERTAIN TRANSACTIONS

     In December 1995 ATSI entered into an agreement with Boles & Company, Inc.
("BCI"), an investment banking firm of which ATSI Merger Corp. director Terry
Colbert is a partner, for the provision of certain investment banking services,
including the location of a potential long-term strategic investment partner.
On April 24, 1996, this agreement was extended for a period of 120 days.  As
compensation for providing services, BCI will receive an engagement fee of
$15,000 in Common Shares for each month during the term of the agreement.  Upon
completion of an equity financing, BCI will receive a fee equal to 6% of the
first $10,000,000 of each such financing and 4% of all amounts in excess of
$10,000,000.  Upon completion of a non-convertible subordinated debt financing,
BCI will receive a fee equal to 4% of the first $10,000,000 of each such
financing and 3.5% of all amounts in excess of $10,000,000.  Upon completion of
a senior debt financing, BCI will receive a fee equal to 2% of all amounts of
senior debt and non-subordinated debt financed.  In the event that transactions,
business associations or other arrangements are initiated by BCI and concluded
with BCI's active involvement, then BCI and ATSI will negotiate in good faith
the amount of completion fees due BCI.  In the event that a financing
transaction is concluded with certain other entities, BCI's success fee will be
30% of the fees set forth above.

     Upon the successful closing of each financing transaction, ATSI will issue
to BCI warrants to purchase up to 5% of the amount of Common Shares associated
with each financing (or such amount of Common Shares as is equal to 5% of the
proceeds received in connection with each financing). Such warrants will be
exercisable for a period of 48 months following the closing of the transaction.
All monthly engagement fees will be credited to completion fees due BCI.

     It is also anticipated that ATSI will execute a service agreement with 
ATSI-Mexico during the current fiscal year to provide, among other things,
engineering, maintenance and network access services. An independent accounting
firm will audit the prices charged by ATSI for the performance of such services
to ensure that such prices will be competitive.

     The following table sets forth certain information regarding the beneficial
ownership of the Common Shares (without taking into effect the one-for-two
reverse stock split to be effected in the First Consolidation) as of May 15,
1996, by (i) each person known by the Company to beneficially own more than 5%
of such shares, (ii) each current and anticipated director of the Company, (iii)
the Named Executive Officer, and (iv) all directors and executive officers as a

                DESCRIPTION OF THE ATSI MERGER CORP. SECURITIES

     The following summary description of the capital stock of ATSI Merger Corp.
does not purport to be complete and is qualified in its entirety by reference to
the ATSI Merger Corp. Certificate and Bylaws, copies of which are attached as
Exhibit H and Exhibit I, respectively. Furthermore, except as noted, the
following discussion describes the capital stock of the Company assuming that
the Domestication and Merger have already been effected. If the Domestication
occurs but the Merger does not, the following description will also apply to the
securities of ATSI as a Delaware corporation. (Currently, the authorized capital
stock of ATSI consists of an unlimited number of Common Shares, no par value per
share.)

GENERAL

     The authorized capital stock of ATSI Merger Corp. consists of 55,000,000
shares of Common Stock, $0.001 par value per share, 9,982,656 of which (assuming
a one-for-two share consolidation to be effected in the First Consolidation)
will be issued and outstanding immediately following the Merger, and 5,000,000
shares of Preferred Stock, par value $0.001 per share ("Preferred Stock"), none
of which will be issued and outstanding immediately following the Merger.

COMMON STOCK

     Subject to the rights of holders of Preferred Stock then outstanding,
holders of Common Stock are entitled to receive such dividends as may from time
to time be declared by the Board of Directors of ATSI Merger Corp. Holders of
Common Stock are entitled to one vote per share on all matters on which the
holders of Common Stock are entitled to vote. Because holders of Common Stock do
not have cumulative voting rights, the holders of a majority of the shares of
Common Stock represented at a meeting can select all of the directors. In
addition, super majority voting requirements apply in respect of certain
stockholder actions.

     Holders of Common Stock have no preemptive rights to subscribe for any
additional securities that ATSI Merger Corp. may issue and there are no
redemption provisions or sinking fund provisions applicable to the Common Stock,
nor is the Common Stock subject to calls or assessments by ATSI Merger Corp. All
shares of Common Stock to be outstanding upon completion of the Domestication
and Merger will be legally issued, fully paid and nonassessable. Upon the
liquidation, dissolution or winding up of ATSI Merger Corp., holders of the
shares of Common Stock are entitled to share equally, share-for-share, in the
assets available for distribution after payment to all creditors of ATSI Merger
Corp., subject to the rights, if any, of the holders of any outstanding shares
of Preferred Stock.

PREFERRED STOCK

     Pursuant to the ATSI Merger Corp. Certificate, the Board of Directors of
ATSI Merger Corp. is authorized, subject to any limitations prescribed by law,
to provide for the issuance of shares of Preferred Stock from time to time in
one or more series and to establish the number of shares to be included in each
such series and to fix the designation, powers, preferences and relative,
participating, optional and other special rights of the shares of each such
series and any qualifications, limitations or restrictions thereof. Because the
Board of Directors has such power to establish the powers, preferences and
rights of each series, it may afford the holders of Preferred Stock preferences,
powers and rights (including voting rights) senior to the rights of the holders
of Common Stock. Although ATSI Merger Corp. has no current intention to issue
shares of Preferred Stock, the issuance of such shares, or the issuance of
rights to purchase such shares, could be used to discourage an unsolicited
acquisition proposal.

</TABLE>

     ATSI has also agreed to issue warrants to Boles & Company, Inc. ("BCI"), of
which ATSI Merger Corp. director Terry Colbert is a partner, pursuant to the
agreement to provide investment banking services entered into between ATSI and
BCI, to purchase up to 5% of the amount of Common Shares associated with each
financing transaction (or such amount of Common Shares as is equal to 5% of the
proceeds received in connection with each financing), upon the successful
closing of such transaction.

     The Company currently has no outstanding options.

     The Company has guaranteed a 12% convertible promissory note in the
original principal amount of $100,000.00 made by ATSI-Texas, due on July 1,
1996. Pursuant to the terms of such note, upon maturity the payee has the option
to (i) be repaid the principal amount of the note plus accrued interest thereon,
(ii) exchange the note for Common Shares on the basis of two Common Shares for
each dollar of principal and interest then outstanding on the note, or (iii)
extend the note at 12% interest for consecutive 90-day periods with the same
right of exchange. The note has thus far been extended in this manner five
times.

PROVISIONS HAVING POSSIBLE ANTI-TAKEOVER EFFECTS

     The Certificate of Incorporation (the "Certificate") and the Bylaws of ATSI
Merger Corp. contain provisions that could have an anti-takeover effect. These
provisions are intended to enhance the likelihood of continuity and stability in
the composition of the Board of Directors and in the policies formulated by the
Board of Directors and to discourage certain types of transactions which may
involve an actual or threatened change of control of ATSI Merger Corp. The
provisions are designed to reduce the vulnerability of ATSI Merger Corp. to an
unsolicited proposal for a takeover of ATSI Merger Corp. that does not
contemplate the acquisition of all of its outstanding shares or an unsolicited
proposal for the restructuring or sale of all or part of ATSI Merger Corp. The
provisions are also intended to discourage certain tactics that may be used in
proxy contests. Set forth below is a description of such provisions in the
Certificate and the Bylaws. The Board of Directors has no current plant to
formulate or effect additional measures that could have an anti-takeover effect.

     Pursuant to the Certificate, directors, other than those, if any, elected
by the holders of Preferred Stock, can be removed from office by the affirmative
vote of the holders of 66% of the voting power of the then outstanding shares
of capital stock entitled to vote thereon ("Voting Stock"). Vacancies on the
Board of Directors may be filled by the remaining directors without stockholder
approval.

                                       80
<PAGE>
 
     The Certificate provides for the Board of Directors to be divided into
three classes, with staggered three-year terms. As a result, only one class of
directors will be elected at each annual meeting of stockholders of ATSI Merger
Corp., with the other classes continuing for the remainder of their respective
three-year term. The classification of the Board of Directors makes it more
difficult to replace the Board of Directors as well as for another party to
obtain control of ATSI Merger Corp. by replacing the Board of Directors. Since
the Board of Directors has the power to retain and discharge officers of ATSI
Merger Corp., these provisions could also make it more difficult for existing
stockholders or another party to effect a change in management.

     ATSI Merger Corp. is subject to the provisions of Section 203 of the DGCL.
In general, Section 203 prohibits a publicly-held Delaware corporation from
engaging in a "business transaction" with an "interested stockholder" for a
period of three years after the date that the person became an interested
stockholder unless (with certain exceptions) the business combination or the
transaction in which the person became an interested stockholder is approved in
a prescribed manner. A "business combination" generally includes, without
limitation, a merger, assets or stock sale, or a transaction resulting in a
financial benefit to the interested stockholder. An "interested stockholder"
generally is a person who, together with affiliates and associates, owns (or
within three years prior, did own) 15% or more of a corporation's outstanding
voting stock.

     The Certificate provides that except as otherwise provided for with respect
to the rights of holders of Preferred Stock, no action that is required or
permitted to be taken by the stockholders of ATSI Merger Corp. at any annual or
special meeting of the stockholders may be effected by written consent of the
stockholders in lieu of a meeting of stockholders, unless the actions to be
effected by written consent of the stockholders and the taking of such action by
such written consent has been expressly approved in advance by the Board of
Directors. This provision makes it difficult for stockholders to initiate or
effect an action by written consent, and thereby effect an action opposed by the
Board of Directors. The Certificate and Bylaws also provide that special
meetings of stockholders may be called only by the Chief Executive Officer or a
majority of the Board of Directors of ATSI Merger Corp. In addition, the Bylaws
set forth an advance notice procedure with regard to business to be brought
before an annual meeting of stockholders of ATSI Merger Corp.

     The Certificate further provides that the Board of Directors, by a majority
vote, may adopt, alter, amend or repeal provisions of the Bylaws. However,
stockholders may only adopt, alter, amend or repeal provisions of the Bylaws by
a vote of 66% or more of the combined voting power of the then outstanding
Voting Stock. In addition, the Certificate provides that whenever any vote of
Voting Stock is required by law to amend, alter, repeal or rescind ("Change")
any provision thereof, then, in addition to any affirmative vote required by law
the affirmative vote of 66% or more of the combined voting power of the then
outstanding shares of Voting Stock is required to Change certain provisions of
the Certificate, including the provisions referred to above relating to
interested stockholder transactions, the filling of vacancies on the Board of
Directors, the removal of directors, the limitations on stockholder action by
written consent, the calling of special meetings by stockholders and the
approval of amendments to the ATSI Merger Corp.'s Bylaws.

     Pursuant to the Certificate, the Board of Directors is also authorized to
issue shares of "blank check" preferred stock that may have the effect of
discouraging an unsolicited acquisition proposal. See "--Preferred Stock."

CANADIAN DEALING NETWORK

     The Company's Common Shares are currently listed on the Canadian Dealing
Network under the symbol ATIL.CDN. ATSI expects that the ATSI Merger Corp.
Common Stock will be listed on the Canadian Dealing Network upon the
effectiveness of the Merger. Furthermore, the Company, or ATSI Merger Corp. in
the event the Merger occurs, may in the future apply for listing on the Nasdaq
National Market, Nasdaq SmallCap Market or another securities market or
exchange, which listing may require the satisfaction of certain conditions,
including without limitation minimum per share price requirements.

EXCHANGE AGENT, TRANSFER AGENT AND REGISTRARS

     The Exchange Agent for exchange of stock certificates following the Merger
will be The R-M Trust Company, at its principal offices at 393 University
Avenue, Toronto, Ontario, M5G 1E6. The Transfer Agent and Registrar for the
Common Shares is The R-M Trust Company.

DIVIDEND POLICY

     The Company has never paid cash dividends on its common equity securities.
The Company's current policy is to retain earnings, if any, to finance the
anticipated growth of its business. Any further determination as to the payment
of dividends will be made at the discretion of the Board of Directors and will
depend upon the Company's operating results, financial condition, capital
requirements, general business conditions and such other factors as the Board of
Directors deems relevant. The Company may procure credit from third parties for
additional capital for expansion and business development activities. It is
likely that any credit facility procured by the Company may limit or restrict
the Company's ability to pay cash dividends on the Common Stock under certain
circumstances.

REGISTRATION RIGHTS

     The 30,000 warrants issued to Robert G. Watt contain "piggyback"
registration rights that allow the holders thereof to require the Company to
register the underlying shares of common stock in the event the Company files a
registration statement under the Securities Act. These rights expire in December
31, 1999.

             CANADIAN AND UNITED STATES INCOME TAX CONSIDERATIONS

     The Consolidation, Domestication and Merger will result in certain income
tax consequences in both the United States and Canada, which management believes
will have a positive effect on the Company by reducing, over the long term,
income taxes paid by the Company and giving the Company the flexibility to enter
into certain types of mergers, acquisitions and combination transactions with
United States corporations which could result in adverse tax consequences absent
the Domestication. Certain tax consequences of the Consolidation, Domestication
and Merger are summarized below.

     THE FOLLOWING SUMMARY IS OF A GENERAL NATURE ONLY AND IT IS NOT INTENDED TO
BE, NOR SHOULD IT BE CONSTRUED TO BE, LEGAL OR TAX ADVICE TO ANY SHAREHOLDER OR
HOLDER OF WARRANTS OF THE COMPANY. ACCORDINGLY, SHAREHOLDERS AND HOLDERS OF
WARRANTS OF THE COMPANY SHOULD CONSULT THEIR OWN TAX ADVISORS FOR ADVICE WITH
RESPECT TO THE FEDERAL INCOME TAX CONSEQUENCES TO THEM OF THE PROPOSED
CONSOLIDATION, DOMESTICATION, THE EXERCISE OF DISSENT RIGHTS AND THE PROPOSED
MERGER.

UNITED STATES TAX CONSEQUENCES

     GENERAL

     The following is a summary of the material United States federal income tax
consequences of the Consolidation, Domestication and Merger (collectively, the
"Domestication Transactions") and the material United States federal income and
estate tax consequences to Non-U.S. Holders (as defined below) of holding and
disposing of the Common Stock (as defined below) of ATSI Merger Corp.

     The summary is based on current law, which is subject to change (possible
retroactively). The summary does not discuss all aspects of United States
taxation that may be relevant to security holders in light of their personal
investment circumstances or to certain security holders subject to special
treatment under United States tax laws (such as securities dealers, tax-exempt
entities (including qualified retirement plans) and insurance companies) and
does not discuss the tax consequences under state, local, or foreign laws. In
particular, this summary does not discuss the tax consequences to holders of
Warrants who have received their Warrants in connection with services rendered
to the Company. Security holders are urged to consult their own tax advisors
regarding the federal, state, local, and other tax considerations of
participating in the Domestication Transactions and of holding and disposing of
shares of ATSI Merger Corp and Warrants.

     The term "U.S. Holder" means a beneficial owner of the stock of the Company
that is for United States federal income tax purposes (i) a citizen or resident
of the United States, (ii) a corporation or partnership created or organized in
the United States or under the laws of the United States or of any State thereof
or (iii) an estate or trust whose income is includable in gross income for
United States federal income tax purposes regardless of its source. The term
"Non-U.S. Holder" means a beneficial owner of the stock of the Company that is
not a U.S. Holder.

     CONSEQUENCES TO THE COMPANY

     Consolidation.  The Consolidation will not constitute a taxable event to
the Company for United States federal income tax purposes.

     Domestication and Merger.  Although the matter is not free of doubt, the
Company believes that the Domestication and Merger will be treated as a single
transaction for United States federal income tax purposes by which ATSI
transfers its assets to ATSI Merger Corp. and ATSI Merger Corp. issues its
Common Stock in exchange for the Common Shares of ATSI. Further, the Company
believes that the Domestication and

                                       83
<PAGE>
 
Merger will qualify as a reorganization within the meaning of Section
368(a)(1)(F) of the Internal Revenue Code of 1986. Accordingly, the Company will
recognize no gain and will incur no United States federal income tax as a result
of the Domestication and Merger.

     CONSEQUENCES OF THE DOMESTICATION TRANSACTIONS TO U.S. HOLDERS

     Consolidation.  Generally, U.S. Holders exchanging shares in the
Consolidation will not recognize gain or loss on such exchange. However, a U.S.
Holder who has held 10% or more of the total voting power of all classes of
stock of the Company entitled to vote at any time during the five year period
ending on the date of the Consolidation would include in income its pro rata
portion of certain of ATSI's earnings and profits. Management of the Company has
determined that the Company has no earnings and profits for this purpose.
Subsequent to the Consolidation, each U.S. Holder of Common Shares will have an
aggregate adjusted tax basis in its Common Shares equal to such U.S. Holder's
aggregate adjusted tax basis prior to the Consolidation.

     Domestication and Merger.  U.S. Holders who exchange their Common Shares in
ATSI for Common Stock in ATSI Merger Corp. pursuant to the Domestication and
Merger will recognize no gain or loss for United States federal income tax
purposes. A U.S. Holder who dissents from the Domestication and Merger and
receives cash in exchange for his Common Shares will recognize gain or loss,
measured by the difference between the Holder's basis in his Common Shares and
the amount of cash received.

     The total basis of Common Stock received by a shareholder will equal his
total basis in the Common Shares surrendered in the exchange. The holding period
for Common Stock will be the same as such shareholder's holding period for the
Common Shares surrendered, provided that the shares were held as a capital
asset.

     Generally, a shareholder's basis in each share of the Common Stock received
would equal such shareholder's total basis in the Common Shares surrendered
divided by the total number of shares of Common Stock received. However, the
basis and holding period of specific shares of Common Stock (including shares of
different classes) may be determined solely by reference to the basis and
holding period of specific Common Shares surrendered if the shareholder can
specifically identify such shares.

     Pursuant to Temporary Treasury regulation Section 7.367(b)-7(c), exchanging
U.S. Holders who have held 10% or more of the total voting power of all classes
of stock of the Company entitled to vote at any time during the 5 year period
ending on the effective date of the Domestication and Merger would include in
income (as dividend income) their pro rata portion of ATSI's earnings and
profits attributable to the stock exchanged to the extent that the fair market
value of the stock exchanged exceeds its basis. The basis of the Common Stock
received by certain foreign corporations treated as U.S. Holders pursuant to
Temporary Treasury regulation Section 7.367(b)-2(b) would then be increased by
such amount. However, management has determined that the Company has no earnings
and profits for this purpose.

     Each exchanging U.S. Holder must file with his District Director of the
Internal Revenue Service on or before the last day for filing his federal income
tax return (determined by taking into account any extensions of time therefor)
for the year in which the Domestication Transactions are consummated, the notice
required by Temporary Treasury regulation Section 7.367(b)-1(c). Any such U.S.
Holder who fails to file the necessary notice and who fails to establish
reasonable cause for such failure may be denied the benefit of the federal
income tax consequences specified above.

                                       84
<PAGE>
 
     CONSEQUENCES OF THE DOMESTICATION AND MERGER TO NON-U.S. HOLDERS

     A Non-U.S. Holder who dissents and receives cash in exchange of his Common
Shares will recognize gain or loss in the manner described above for U.S.
Holders. A Non-U.S. Holder will not be subject to United States federal income
tax with respect to capital gains unless (i) such gain is effectively connected
with the conduct of a trade or business within the United States by such holder,
(ii) such holder is an individual who has been present in the United States for
at least 183 days during the taxable year of the disposition, the Common Stock
is a capital asset and either (a) such individual's "tax home" for federal
income tax purposes is in the United States or (b) the gain is attributable to
an office or other fixed place of business maintained in the United States by
such individual, or (iii) the Company is or has been a "United States real
property holding corporation" for federal income tax purposes and the Non-U.S.
Holder owned directly or pursuant to certain attribution rules at any time
during the five-year period ending on the date of disposition more than 5% of
the Company's Common Stock (assuming that Common Stock is regularly traded on an
established securities market). The Company believes that it is not presently a
United States real property holding corporation.

     CONSEQUENCES OF THE DOMESTICATION AND MERGER ON HOLDERS OF WARRANTS

     Although the matter is not free from doubt, for United States federal
income tax purposes, the Domestication and Merger should not result in the
recognition of gain or loss under Section 1001 of the Code to the holders of
Warrants in ATSI. The IRS or the courts could disagree with this
characterization of the results to Warrant holders and instead treat the
transaction in connection with the Warrants as a taxable exchange. In such
event, each U.S. Holder of Warrants will recognize gain or loss on the exchange
equal to the difference between the fair market value of its Warrants prior to
the Merger and the adjusted tax basis of its Warrants of ATSI (which such gain
or loss will be capital gain or loss if the Warrants are capital assets that
have been held for more than one year). Non-U.S. Holders of Warrants will not be
subject to United States federal income tax with respect to capital gains
(resulting from the Merger) unless (i) such gain is effectively connected with
the conduct of a trade or business within the United States by such holder, (ii)
such holder is an individual who has been present in the United States for at
least 183 days during the taxable year of the disposition, the Warrants are
capital assets and either (a) such individual's "tax home" for federal income
tax purposes is in the United States or (b) the gain is attributable to an
office or other fixed place of business maintained in the United States by such
individual, or (iii) the Company is or has been a "United States real property
holding corporation" for federal income tax purposes and the Non-U.S. Holder of
Warrants is treated as owning directly or indirectly or pursuant to certain
attribution rules at any time during the five-year period ending on the date of
disposition more than 5% of the Company's Common Stock (assuming that the Common
Stock is regularly traded on an established securities market). The Company
believes that it is not presently a United States real property holding
corporation. Each holder of Warrants is urged to consult its own tax advisor
regarding the tax consequences of the Domestication and Merger on its particular
circumstances. See "Risk Factors--Risks Relating to Ownership of Company
Securities and this Offering--Tax Consequences of the Domestication and Merger
on Holders of Warrants."

     CONSEQUENCES TO NON-U.S. HOLDERS OF OWNING AND DISPOSING OF ATSI MERGER
  CORP. COMMON STOCK

     Dividends.  Generally, dividends paid to a Non-U.S. Holder of Common Stock
will be subject to United States withholding tax at the rate of 30% of the
amount of the dividend, or at a lower applicable treaty rate. Under the income
tax treaty between the United States and Canada, the withholding tax rate on
dividends paid to most shareholders who are resident in Canada will be 15%. In
the case of Canadian corporations that beneficially own 10% or more of the
voting stock of ATSI Merger Corp., such withholding rate will be 5% (6% if paid
in 1996). Under current Treasury regulations, dividends paid to an address
outside the United States are presumed to be paid to a resident of such country
for purposes of determining the applicability of a treaty rate. Under proposed
Treasury regulations not currently in effect, however, a holder of Common

                                       85
<PAGE>
 
Stock who wished to claim the benefit of an applicable treaty rate would be
required to file certain forms with the Company or its agent. Such Forms would
contain the holder's name and address and other pertinent information certified
by such holder under penalties of perjury.

     If, however, the dividend is effectively connected with the conduct of a
trade or business within the United States by a Non-U.S. Holder, the dividend
will be subject to regular United States federal income tax, which is not
collected by withholding, provided the Non-U.S. Holder files an Internal Revenue
Service Form 4224 with the Company or its agent in accordance with current
treasury regulations. Moreover, in the case of a Non-U.S. Holder that is a
corporation, a branch profits tax at the rate of 30% (or a lower applicable
treaty rate) may be imposed on such corporation on its earnings (including
dividends) effectively connected with a United States trade or business to the
extent that such earnings are considered to be repatriated away from the United
States trade or business.

     Sale of Common Stock.  A Non-U.S. Holder will not be subject to United
States federal income tax on any gain recognized upon the sale (or other
disposition) of Common Stock unless (i) such gain is effectively connected with
the conduct of a trade or business within the United States by such holder, (ii)
such holder is an individual who has been present in the United States for at
least 183 days during the taxable year of the disposition, the Common Stock is a
capital asset and either (a) such individual's "tax home" for federal income tax
purposes is in the United States or (b) the gain is attributable to an office or
other fixed place of business maintained in the United States by such
individual, or (iii) the Company is or has been a "United States real property
holding corporation" for federal income tax purposes and the Non-U.S. Holder
owned directly or pursuant to certain attribution rules at any time during the
five-year period ending on the date of disposition more than 5% of the Company's
Common Stock (assuming that Common Stock is regularly traded on an established
securities market). The Company believes that it is not presently a United
States real property holding corporation.

     Estate Tax.  Common Stock owned (or treated as owned) by an individual who,
at the time of death, is neither a citizen or a domiciliary of the United States
will be includable in his gross estate for United States federal estate tax
purposes and thus may be subject to United States estate tax, unless an
applicable estate tax treaty provides otherwise.

     INFORMATION REPORTING AND BACKUP WITHHOLDING

     The Company must report annually to the Internal Revenue Service and to
each shareholder the amount of cash proceeds paid as a result of the
Domestication Transactions and dividends paid to, and the tax withheld with
respect to, each shareholder. These reporting requirements apply regardless of
whether withholding was reduced by an applicable tax treaty or not required.
Copies of these information returns may also be made available under the
provisions of a specific treaty or agreement with the tax authorities in the
country in which a Non-U.S. Holder resides.

     Shareholders may be subject to backup withholding at the rate of 31% with
respect to cash proceeds from the Domestication Transactions, gross proceeds
from the sale of the Common Stock, or dividends paid on the Common Stock, unless
such holder (a) is a corporation or comes within certain other exempt categories
or (b) provides a correct taxpayer identification number, certifies as to no
loss of exemption from backup withholding, and otherwise complies with
applicable requirements of the backup withholding rules. A shareholder who does
not provide the Company with his correct taxpayer identification number may be
subject to penalties imposed by the Internal Revenue Service. United States
backup withholding tax will generally not apply to payments to a payee at an
address outside the United States unless the payor has knowledge that the payee
is a United States person.

     Payment to a Non-U.S. Holder of the proceeds of a sale of Common Stock to
or through a United States office of a broker will be subject to information
reporting and backup withholding unless the holder certifies

                                       86
<PAGE>
 
as to its status as a Non-U.S. Holder under penalties of perjury or otherwise
establishes an exemption. Payment of the proceeds of a sale of Common Stock to
or through a non-U.S. office of a broker generally will not be subject to backup
withholding or information reporting; however, if such holder is (i) a United
States person, (ii) a "controlled foreign corporation," or (iii) a foreign
person that derives 50% or more of its gross income from the conduct of a trade
or business in the United States, such payment will be subject to information
reporting (but currently not backup withholding) unless such broker has
documentary evidence in its records that the holder is a Non-U.S. Holder and
certain other conditions are met or the holder otherwise establishes an
exemption.

     Any amounts withheld under the backup withholding rules will be credited
against the shareholder's federal income tax liability, if any, or refunded,
provided the required information is furnished to the Internal Revenue Service.

CANADIAN FEDERAL INCOME TAX CONSEQUENCES

     The following is a general summary of the principal Canadian federal income
tax consequences under the Income Tax Act (Canada) (the "Canadian Act") and the
Canada-US Tax Convention (1980) (the "U.S. Treaty") of the Consolidation,
Continuance and Merger and the exercise of dissent rights as described herein to
shareholders and holders of Warrants of the Company.

     This summary is based upon and takes into account the current provisions of
the Canadian Act and the current regulations thereunder (the "Regulations"), all
specific proposals to amend the Canadian Act and the Regulations publicly
announced by the Minister of Finance prior to the date hereof (the
"Amendments"), and the Company's understanding of the current administrative
practices published by Revenue Canada ("RCT"). This summary does not otherwise
take into account or anticipate any changes in law, whether by judicial,
governmental or legislative decision or action, nor, except as specifically
noted herein, does it take into account tax laws or considerations of any
province or territory of Canada or any jurisdiction outside Canada. Moreover,
there can be no assurance that the Amendments will be enacted as proposed or
that the Canadian Act, the Regulations thereunder or the administrative
practices of RCT, respectively, will not change, in a manner which will affect
the tax consequences of the transactions to the Company, the shareholders or the
holders of Warrants.

     This summary is based on the facts and agreements described herein and is
also based on the assurances of management of the Company that no other
transactions have been undertaken or are contemplated that would affect the
matters dealt with herein.

     This summary is restricted to those shareholders and holders of Warrants of
the Company who, for purposes of the Canadian Act, are resident in Canada, deal
at arm's length with the Company and hold their shares or Warrants as capital
property. A share or Warrant will generally be capital property to holders
unless it is held in the course of carrying on a business of trading or dealing
in securities, has been acquired in a transaction or transactions considered to
be an adventure in the nature of trade, or is a mark-to-market property of
certain financial institutions.

     This summary is of a general nature only, is not exhaustive of all
potentially relevant Canadian federal income tax considerations and is not
intended to be, nor should it be construed to be, legal or tax advice to any
particular shareholder or holder of Warrants. Therefore, shareholders and
holders of Warrants should consult their own tax advisers with respect to their
particular circumstances.

                                       87
<PAGE>
 
     CONSOLIDATION

     The Consolidation will not constitute a taxable event for the Company's
shareholders or holders of Warrants. The Company's shareholders and holders of
Warrants will continue to hold their shares or Warrants at the same aggregate
adjusted cost base as before the Consolidation.

     CONTINUANCE

     Shareholders Consequences.  The Continuance will not constitute a taxable
event for the Company's shareholders or holders of Warrants. Shareholders or
holders of Warrants of the Company will continue to hold their shares or
Warrants at the same adjusted cost base as before the Continuance.

     Any dividends paid by the Company to its shareholders on the Common Shares
after the Continuance must be included in computing their income.

     After the Continuance, in the case of shareholders who are individuals,
dividends received on Common Shares, as dividends on shares of a foreign
corporation, will not be entitled to the benefit of the gross up and dividend
tax credit rules in the Canadian Act. After the Continuance, in the case of
corporate shareholders of which the Company is not a foreign affiliate for
purposes of the Canadian Act, dividends received on Common Shares are not
deductible in computing taxable income.

     Under the U.S. Treaty, the U.S. withholding tax on dividends paid by the
Company after the Continuance will be 15% in most cases, and 5% (6% for
dividends paid in 1996) in the case of a Canadian corporation that owns at least
10% of the voting stock of the Company at the time the dividend is paid.

     U.S. withholding taxes imposed on such dividends may either be credited
against Canadian taxes payable by the investor, or deducted by such investor in
computing income for Canadian tax purposes, at the investor's option, subject to
the detailed rules in the Canadian Act in that regard.

     Special rules apply to corporate shareholders that receive dividends from a
foreign affiliate and such shareholders are advised to consult their own tax
advisers with respect thereto.

     Dissenting Shareholders.  The consequences under the Canadian Act to a
shareholder who dissents from the Continuance described herein and who receives
a payment for his or her shares are discussed below.

     The receipt by a dissenting shareholder of a cash payment from the Company
equal to the fair value of his or her Common Shares prior to the completion of
the Continuance will generally be treated as a dividend to the holder of such
shares to the extent that such payment exceeds the paid-up capital for purposes
of the Canadian Act of the subject shares. The balance of the fair value paid
(i.e. the amount equal to the paid-up capital of the shares) will generally be
treated as proceeds of disposition of the subject shares for capital gains
purposes. Consequently, such dissenting shareholders would realize a capital
gain (capital loss) to the extent that the proceeds of disposition he or she
receives for the share exceed (are exceeded by) the shareholder's adjusted cost
base thereof. Notwithstanding the foregoing, if the dissenting recipient
shareholder is a corporation resident in Canada, the full amount of the
redemption proceeds received may be treated under the Canadian Act as proceeds
of disposition, with the result that no dividend will be deemed to have been
paid to the shareholder and any gain or loss realized by it upon disposition of
the shares will be determined by reference to the full amount of the redemption
proceeds. Corporate shareholders should consult their own advisor with respect
to the applicability of these provisions.

     If the dissenting shareholder receives such cash payment after the
Continuance, the payment will be treated as proceeds of disposition of the
subject shares for capital gains purposes. Accordingly, the dissenting
shareholder will realize a capital gain or loss as described above.

                                       88
<PAGE>
 
     Any capital loss arising on the exercise of dissent rights by a corporate
shareholder of the Company will be reduced by dividends received or deemed to be
received, including any deemed dividend arising from the exercise of dissent
rights, on the subject shares to the extent and under the circumstances
prescribed in the Canadian Act. Similar rules apply where a corporation is a
member of a partnership or a beneficiary of a trust that owns shares of the
Company. Under the Amendments, these rules will be extended to apply where a
trust or partnership is a member of a partnership or a beneficiary of a trust
that owns shares of the Company.

     Company Consequences.  The "corporate emigration" rules under the Canadian
Act will apply upon Continuance. Accordingly, the Company will be deemed to have
completed a taxation year immediately prior to it being granted articles of
continuance in Delaware. In addition, each property owned by the Company
immediately before the deemed year-end will be deemed to have been disposed by
it for proceeds of disposition equal to that property's fair market value and
immediately reacquired at a cost equal to such proceeds of disposition. Any
gains or losses derived by the Company from such deemed disposition of property
will be taken into account in determining the amount of the Company's taxable
income for the taxation year which ends immediately before the Continuance. The
amount of any taxable income so determined will be subject to tax in accordance
with the provisions of the Canadian Act.

     The Company will also be required to pay a special branch tax applicable to
the amount by which the fair market value of the Company's property exceeds the
aggregate of its liabilities, including any liabilities under the Canadian Act
(other than the special branch tax itself), and the paid-up capital of its
issued and outstanding shares at the time of the Continuance. The rate of tax
under the U.S. Treaty is 6%, on the assumption that the Continuance occurs in
1996.

     Following completion of the Continuance, the Company will be considered to
be a resident of the United States for Canadian tax purposes. Accordingly, it
would only be required to pay Canadian tax on Canadian-source income rather than
on its worldwide income.

     MERGER

     Company Consequences.  The Company expects that there will be no material
adverse Canadian tax consequences to it from the Merger.

     Shareholders Consequences.  Unless a shareholder elects otherwise, the
shareholder will not realize a capital gain or a capital loss on the Merger. The
cost of the Common Stock of ATSI Merger Corp. received by a shareholder of ATSI
as a result of the Merger will be equal to the aggregate adjusted cost base of
the Common Shares that are so exchanged. Following the Merger, dividends
received on the ATSI Merger Corp. Common Stock will be treated in the same way
as dividends on the Common Shares received after the Continuance, as described
above.

     Consequences to Holders of Warrants.  While the matter is not free from
doubt, a holder of Warrants of ATSI will likely be regarded as having disposed
of the Warrants on the Merger for proceeds of disposition equal to the fair
market value of the Warrants, thereby giving rise to a capital gain (capital
loss) equal to the amount by which such proceeds of disposition exceed (are
exceeded by) the holder's adjusted cost base of the Warrants of ATSI.

     ELIGIBILITY FOR INVESTMENT UNDER THE CANADIAN ACT

     Following the Continuance, the Common Shares or the ATSI Merger Corp.
Common Stock, as the case may be, will not be qualified investments under the
Canadian Act for trusts governed by registered retirement savings plans,
registered retirement income funds and deferred profit sharing plans until the
Common Shares or the ATSI Merger Corp. Common Stock, as the case may be, are
listed on a prescribed stock exchange.

                                       89
<PAGE>
 
Following the Continuance, the Common Shares or the ATSI Merger Corp. Common
Stock, as the case may be, will be considered foreign property for the purposes
of the foreign property limitations under the Canadian Act subject, however, to
a 24 month grace period that generally applies to shares that had been held, or
were exchanged on the Merger for shares that had been held, prior to the
Continuance. Pursuant to the Amendments, however, if an entity subject to the
foreign property limitations acquired all of its Common Shares after 1995,
otherwise than as a consequence of the exercise of rights acquired before 1996,
its Common Shares will be classified as foreign property from the time of
acquisition and it will not be eligible for such 24 month grace period.

                                 LEGAL OPINIONS

  Certain legal matters relating to the Domestication and Merger have been
passed upon for the Company by Akin, Gump, Strauss, Hauer & Feld, L.L.P., San
Antonio, Texas.


                       OTHER BUSINESS AT SPECIAL MEETING

  While there is no business other than that mentioned in the Notice of Meeting
to be presented for action by the shareholders at the Meeting, it is intended
that the proxies for the Meeting solicited hereby will be exercised upon any
other matters and proposals that may properly come before the Meeting in
accordance with the discretion of the person authorized to act thereunder.


                             APPROVAL OF PROSPECTUS

  This Prospectus and the enclosed forms of proxy, and the sending thereof the

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS



To the Board of Directors and Stockholders of
American Telesource International Inc.:

We have audited the accompanying consolidated balance sheets of American
Telesource International Inc. (an Ontario corporation) and subsidiaries as of
July 31, 1994 and 1995, and the related consolidated statements of loss,
stockholders' equity and cash flows for the period from December 17, 1993
through July 31, 1994 and the year ended July 31, 1995. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of American Telesource
International Inc. and subsidiaries as of July 31, 1994 and 1995, and the
results of their operations and their cash flows for the period from December
17, 1993 through July 31, 1994 and the year ended July 31, 1995, in conformity
with generally accepted accounting principles.

The accompanying consolidated financial statements have been prepared assuming
that the Company will continue as a going concern. As discussed in Note 2 to the
financial statements, the Company has suffered recurring losses from operations
since inception, had a working capital deficit at July 31, 1995, and has limited
capital resources available to support further development of its operations.
Unaudited information indicates that such losses are continuing subsequent to
July 31, 1995. These matters raise substantial doubt about the Company's ability
to continue as a going concern. Management's plans in regard to these matters
are also described in Note 2. The financial statements do not include any
adjustments relating to the recoverability and classification of asset carrying
amounts or the amount and classification of liabilities that might result should
the Company be unable to continue as a going concern.

     The financial information utilized in the following Notes is presented in
U.S. dollars.

     1. BUSINESS ACTIVITY

     The company was originally incorporated under the laws of the province of
Alberta, Canada on December 17, 1993 (date of inception, or "Inception"), under
the name Latcomm International Inc. (Latcomm). On December 20, 1993, Latcomm
purchased all of the outstanding shares of Latin America Telecomm, Inc., a Texas
Corporation, for cash consideration of $25,000. On April 22, 1994 Latin America
Telecomm, Inc. changed its name to American Telesource International, Inc. 
(ATSI-Texas). Effective May 26, 1994 (Effective Date), Latcomm amalgamated under
the Business Corporations Act of Ontario, Canada with Willingdon Resources, Ltd.
(Willingdon), a corporation incorporated under the laws of the Province of
Ontario, Canada. The resulting Ontario Corporation was named American Telesource
International Inc. (ATSI-Canada). In accordance with the amalgamation agreement
between Latcomm and Willingdon, on the Effective Date each four issued and
outstanding shares of Willingdon were converted to one issued and outstanding
share of ATSI-Canada and each issued and outstanding share of Latcomm was
converted to one issued and outstanding share of ATSI-Canada. With the exception
of a $54,824 liability to certain prior shareholders of Willingdon, no assets or
liabilities of Willingdon were assumed by ATSI-Canada. Collectively, ATSI-Texas
and ATSI-Canada are referred to hereafter as "ATSI" or "the Company".

     ATSI conducts its primary operations through ATSI-Texas. ATSI-Texas
provides a full range of private network services via satellite to customers
conducting business in Mexico, Central and South America, and the Caribbean
Basin. These services include the purchasing, exporting, installation and
maintenance of equipment as well as providing voice, data, fax and video
telecommunication services via its teleport facility in San Antonio, Texas. 
ATSI-Texas also provides long distance operator services to the hospitality 
industry and private payphone owners in the U.S. and Mexico.

     On June 20, 1995, ATSI-Texas formed a foreign subsidiary based in Mexico
City, Mexico. The subsidiary, American Telesource International de Mexico, S.A.
de C.V. (ATSI-Mexico), will perform customer service and maintenance operations
within Mexico and serve as a sales office for both private network and long
distance services. ATSI-Mexico has applied for and expects to receive several
licenses to conduct business from the Secretaria de Communicaciones y
Transportes, the regulatory authority in Mexico charged with oversight of the
telecommunications industry in Mexico. However, there can be no assurances that
such licenses will be obtained. See Note 12.

     2. FUTURE OPERATIONS

     The consolidated financial statements of the Company have been prepared on
the basis of accounting principles applicable to a going concern. For the
periods from Inception to July 31, 1995 and January 31, 1996, the Company has
incurred cumulative net losses of $2,347,695 and $3,768,394, respectively.
Further, the Company had working capital deficits of $446,370 and $1,334,331 at
July 31, 1995 and January 31, 1996, respectively, and has limited capital
resources available to support its ongoing developmental operations until such
time as the Company is able to generate positive cash flow from operations.
There is no assurance the Company will be able to achieve future revenue levels
sufficient to support operations or recover its investment in property and
equipment. The Company's future ability to generate revenues is also subject to
uncertainty with regards to certain regulatory matters described in Note 15.
These matters raise substantial

                                     F - 7
<PAGE>
 
doubt about the Company's ability to continue as a going concern. The ability of
the Company to continue as a going concern is dependent upon the ongoing support
of its stockholders and customers, its ability to obtain capital resources to
support developmental operations, the ultimate outcome of certain regulatory
matters as described in Note 15 and its ability to successfully market its
services.

     The Company will require significant additional financial resources in both
the near term and long-term to support its ongoing operations. The Company has
retained various financial advisers to assist it in refining its strategic
growth plan, defining its capital needs and obtaining the funds required to meet
those needs. The plan includes securing funds through equity offerings and
entering into lease or long-term debt financing agreements to raise capital.
There can be no assurances, however, that such equity offerings or other
financing arrangements will actually be consummated or that such funds, if
received, will be sufficient to support existing operations until revenue levels
are achieved sufficient to generate positive cash flow from operations. If the
Company is not successful in completing additional equity offerings or entering
into other financial arrangements, or if the funds raised in such stock
offerings or other financial arrangements are not adequate to support the
Company until a successful level of operations is attained, the Company has
limited additional sources of debt or equity capital and would likely be unable
to continue operating as a going concern.

     Effective for the fiscal year beginning August 1, 1996, the Company will
have to adopt Statement of Financial Accounting Standards No. 121, Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of (SFAS121). SFAS121 requires an assessment of the recoverability of the
Company's investment in long-lived assets to be held and used in operations
whenever events or circumstances indicate that their carrying amounts may not be
recoverable. Such assessment requires that the future cash-flows associated with
the long-lived assets be estimated over their remaining useful lives and an
impairment loss be recognized when the future cash flows are less than the
carrying value of such assets. Management presently cannot reasonably estimate
what potential impact, if any, the adoption of this statement may have on the
financial condition or results of operations of the Company.

     3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Principles of Consolidation and Basis of Presentation
     -----------------------------------------------------

     The accompanying consolidated financial statements include the accounts of
ATSI-Canada, ATSI-Texas and ATSI-Mexico. The consolidated financial statements
have been prepared on the accrual basis of accounting under generally accepted
accounting principles of the U.S. All significant intercompany balances and
transactions have been eliminated in consolidation. Certain prior period amounts
have been reclassified for comparative purposes. The consolidated interim
financial statements as of January 31, 1996 and for the six months ended January
31, 1995 and 1996 included herein have been prepared by the Company without
audit, pursuant to the rules and regulations of the Securities and Exchange
Commission. All adjustments have been made to the accompanying consolidated
interim financial statements which are, in the opinion of the Company's
management, necessary for a fair presentation of the Company's operating
results. All adjustments are of a normal recurring nature. Certain information
and footnote disclosures normally included in financial statements prepared in
accordance with generally accepted accounting principles have been condensed or
omitted pursuant to such rules and regulations.

     As mentioned in Note 1, ATSI-Mexico was formed on June 20, 1995. ATSI-
Mexico is 49% owned by ATSI-Texas, and 51% owned by a Mexican citizen. Mexican
law mandates that any company participating in public communications within
Mexico be majority owned by a Mexican entity. However, ATSI-Texas maintains
significant control over the operations of ATSI-Mexico and has limited the
authority of the other shareholder to sell or transfer his shares. As such, 100%
of the operations of ATSI-Mexico have been consolidated in the accompanying
consolidated financial statements.

                                     F - 8
<PAGE>
 
     The accompanying consolidated financial statements reflect the assets,
liabilities and stockholders' equity of Latcomm, which were transferred to ATSI
on the Effective Date in connection with the amalgamation described in Note 1,
at such predecessor's historical cost basis. The $54,824 liability to certain
former stockholders of Willingdon which was also transferred to ATSI in
connection with the amalgamation has been charged to the accumulated deficit as
of the Effective Date on the accompanying statements of stockholders' equity.

     Estimates in Financial Statements
     ---------------------------------

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results may differ from those estimates.

     Revenue Recognition Policies
     ----------------------------

     The Company recognizes revenue from its operator services as such services
are performed, net of estimated unbillable calls. Revenue from private network
service contracts is recognized when service commences for service commencement
fees and monthly thereafter as services are provided. The Company recognizes
revenue from equipment sales when the title for the equipment transfers to the
customer and from equipment installation projects when they are completed.

     Accounts Receivable
     -------------------

     During fiscal 1995, the Company began utilizing the services of a credit
card processing company for the billing of commercial credit card calls and
receiving cash from these calls, net of transaction and billing fees, generally
within seven days from the dates the calls are delivered. All other calls
(calling card, collect, person-to-person and third-party billed) are billed
under an agreement between the Company and a collection clearinghouse. This
agreement allows ATSI to submit call detail records to the clearinghouse, who in
turn forwards these records to the local telephone company to be billed. The
clearinghouse collects the funds from the local telephone company and then
remits the funds, net of charges, to ATSI. Because this collection process can
take up to 75 days to complete, ATSI participates in an advance funding program
offered by the clearinghouse whereby 100% of the call records are purchased for
75% of their value within five days of presentment. The remaining 25% value of
the call records are remitted to ATSI, net of interest and billing charges and
an estimate for uncollectible calls, as the clearinghouse collects the funds
from the local telephone companies. The allowance for doubtful accounts reflects
the Company's estimate of uncollectible calls at July 31, 1994 and 1995 and
January 31, 1996. ATSI currently pays a funding charge of prime plus 4 percent
per annum on the 75% of the calls which are advanced to ATSI. Receivables sold
with recourse during fiscal year 1995 and the six-month period ended January 31,
1996, were $3,620,056 and $3,045,949, respectively. At July 31, 1995 and January
31, 1996, $396,993 and $357,760 of such receivables remained uncollected,
respectively.

     Earnings Per Share
     ------------------

     Earnings per share were calculated using the weighted average number of
common shares outstanding for the period from Inception to July 31, 1994, the
year ended July 31, 1995, and the six month period ended January 31, 1996, which
equated to 9,146,091 shares, 13,922,018 shares and 19,094,398 shares,
respectively. Common stock equivalents, which consist of the stock purchase
warrants and options described in Note 9, were excluded from the computation of
the weighted average number of common shares outstanding because their effect
was antidilutive.

                                     F - 9
<PAGE>
 
     Property and Equipment
     ----------------------

     Property and equipment are stated at cost. Depreciation is computed on a
straight-line basis over the estimated useful lives of the related assets, which
ranges from five to fifteen years. Expenditures for maintenance and repairs are
charged to expense as incurred. Direct installation costs and major improvements
are capitalized.

     Other Assets
     ------------

     Other assets includes organization costs as of July 31, 1994 and 1995 and
January 31, 1996, of $98,077, $141,226, and $162,462, respectively, net of
accumulated amortization of $2,825, $29,165 and $42,335, respectively.

     Income Taxes
     ------------

     In February 1992, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 109, "Accounting for Income Taxes." Under
SFAS No. 109, deferred tax liabilities and assets are recorded based on enacted
income tax rates that are expected to be in effect in the period in which the
deferred tax liability or asset is expected to be settled or realized. A change
in the tax laws or rates results in adjustments to the deferred tax liabilities
or assets. The effects of such adjustments shall be included in income in the
period in which the tax laws or rates are changed.

     The Company has incurred losses since Inception for both book and tax
purposes as of January 31, 1996. Accordingly, no income taxes have been provided
for in the accompanying consolidated financial statements for the period from
Inception to July 31, 1994, the year ended July 31, 1995 and the six-month
period ended January 31, 1996.

     6.  LEASES

     The Company leases office space, furniture and minor equipment under
noncancelable operating leases and certain month-to-month leases. Rental expense

     7. SHARE CAPITAL

     During the year ended July 31, 1995, the Company issued 5,798,772 shares of
common stock. Of this total, 1,350,423 shares of common stock were issued for
approximately $675,000 in cash through the exercise of 1,350,423 warrants,
4,110,625 shares were issued for approximately $1,646,000 net cash proceeds and
337,724 shares were issued for services rendered to the Company. During the six
month period ended January 31, 1996, 1,229,671 shares of common stock were
issued. Of this total, 975,000 shares were issued for approximately $493,000 in
cash, and 254,671 shares were issued for services rendered to the Company. At
July 31, 1994 and July 31, 1995, stock subscription receivables of $75,000 and
$350,000 respectively, were outstanding related to sales of common stock which
were received in cash by the Company subsequent to the related fiscal year-ends.
No dividends were paid on the Company's stock during the period from Inception
to July 31, 1994, the year ended July 31, 1995 and the six month period ended
January 31, 1996,

     8. DEFERRED REVENUE

     The Company records deferred revenue related to the private network
services it provides. Customers may be required to advance cash to the Company
prior to service commencement to partially cover the cost of equipment and
related installation costs. Any cash received prior to the actual commencement
of services is recorded as deferred revenue until services are provided by the
Company, at which time the Company recognizes service commencement revenue. Such
deferred amounts were $22,335 and $64,987 at July 31, 1994 and 1995,
respectively. At January 31, 1996, the deferred amount of $797,891 consisted
primarily of a cash payment received in December 1995 in connection with a
contract which calls for the Company to sell and install private network
equipment in Mexico for approximately $1.4 million. No revenue related to this
contract has been recognized as of January 31, 1996.

     9. STOCK PURCHASE WARRANTS AND STOCK OPTIONS

     Certain shareholders of the Company were issued warrants to purchase shares
of common stock for $ .50 to $ 1.25 per share. Following is a summary of warrant
activity from July 31, 1994 through July 31, 1995:

</TABLE>

In 1994, the Company issued options to certain individuals to purchase 210,000
shares of common stock.  All the options were exercised in fiscal 1994 for a
total of $ 138,127 and the exercise price for the options ranged from $ .50 to 
$ .72 per share. The exercise price on all the options issued equaled the fair
market value of the Company's common stock on the date of the grant.

     10.  POST EMPLOYMENT BENEFITS

     In December 1991, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 106 (SFAS No. 106), "Employers' Accounting
for Postretirement Benefits Other Than Pensions." In November 1992, the
Financial Accounting Standards Board issued Statement of Financial Accounting
Standards No. 112 (SFAS No. 112), "Employers' Accounting for Postemployment
Benefits." The Company does not provide Postretirement nor Postemployment
benefits to its employees. Thus, SFAS Nos. 106 and 112 does not affect the
Company's results of operations or financial position.

     11.  INCOME TAXES

     As of July 1995, the Company had net operating loss carryforwards of
approximately $2,250,000 for U.S. federal income tax purposes which are
available to reduce future taxable income of which $ 320,000 will expire in
2009, $ 1,930,000 will expire in 2010.  The tax effects of significant temporary
differences representing deferred income tax assets and liabilities are as
follows as of July 31, 1994 and 1995:

     The valuation allowance as of July 31, 1994 and 1995 represents tax
benefits of certain future net operating loss carryforwards amounts which were
not realizable at that date.

     The Company's income tax benefit at the statutory federal income tax rate
for the year ended July 31, 1994 and the period from inception to July 31, 1995
differs from the actual income tax benefit of $0 for those periods ended, as the
Company has provided a valuation reserve equal to the income tax benefit amount
computed at the statutory federal tax rate.

     12.  INTERNATIONAL OPERATIONS

     The Company focuses on providing international satellite-based private
networks and international call services between the United States, Mexico,
Central and South America, and the Caribbean Basin.  From its Inception through
January 31, 1996, all of the Company's revenues have been generated under
contracts calling for payments to be made to the Company in U.S. dollars, even
though some of the contracts have been signed with foreign entities.  The
Company's contracts are U.S. dollar denominated in order to reduce risks of
transacting business in foreign currencies, particularly with regard to Mexican
pesos.

     International networks effectively establish a communications "pipe"
through which voice, date, fax messages and video signals may be sent both to
and from a customer's desired locations in the United States, Mexico, Central
and South America, and the Caribbean Basis. At the customer's discretion, the
Company may contract with either the domestic (U.S.-based) or the foreign entity
in order to provide such services. As of January 31, 1996, the Company had
several contracts with foreign entities to provide international private network
services, the majority of which were with entities in Mexico. If the contract is
signed with a foreign entity, the Company considers the private network-
associated revenues to be generated in the country where the foreign entity is
domiciled. All entities under contract for private network services, whether
considered to be foreign or domestic, are pre-billed on a monthly basis for
services to be performed.

     The Company also provides operator services for many hotels, resorts and
other properties in other countries, primarily Mexico. Although these services
pertain to calls originating in Mexico, they are limited to telephone calls
charged to billing addresses primarily within the United States, or calls billed
to U.S. dollar denominated credit cards. Because the calls are billed and
collected on behalf of the Company within the United States, the Company
considers the associated revenues to be generated within the United States.
However, a portion of the expenses associated with processing these calls is
incurred within Mexico and, as such, is paid to Mexican entities. Because calls
originating from Mexico and the United States are terminated over shared lines
within the United States, the Company has no exact method of segregating all
costs related solely to calls originating in Mexico as of January 31, 1996.

     The following table presents approximate revenues generated from calls
originating within the United States and within Mexico and other countries, in
addition to private network revenues generated within the United States and
within Mexico and other countries, for the periods indicated. Also presented are
identifiable assets owned by the Company in the United States and in Mexico and
other countries.

     13.  EMPLOYEE BENEFITS

     The Company has authorized and issued 300,000 shares of common stock to be
used in the future for employee benefits.  These shares are held in a trust and
are not considered outstanding until they are issued to various individuals.
The shares held in trust vest over the length of the employee contracts, which
is three years.   As of July 31, 1994 and 1995 and January 31, 1996, 12,500,
212,500, and 225,000 of these shares had been granted for services provided,
respectively, resulting in compensation expense totaling $27,778.  At July 31,
1995 and January 31, 1996, the Company had deferred compensation expense of
$11,111 and $72,222, respectively.

     14.  COMMITMENTS AND CONTINGENCIES

     In January 1995, the Company was named as a defendant in a lawsuit filed in
the 45th Judicial District Court in Bexar County, Texas (Teleplus, Inc. and
Capital Network System, Inc. v. American Telesource International, Inc., et al.,
case no. 95-CI-01168).  The complaint, filed by a competitor of the Company,
alleged, among other things, that the Company conspired with former agents of
the plaintiffs to persuade customers of the plaintiffs' to breach their
contracts so that the Company could provide operator services to such customers.
The Company subsequently filed a counterclaim against the plaintiffs claiming
that they engaged in anticompetitive conduct.

     In April 1996, all parties agreed to dismiss all claims, counterclaims and
cross-claims that had been brought or could have been brought related to the
litigation.  The agreement, among other things, established current customer
lists for the parties within Mexico as of April 1996, and sets forth how both
the plaintiffs and defendants may market their services against each other in
the future.  The agreement does not prevent the Company from growing its
customer base within Mexico.

     15.  REGULATORY MATTERS

Operator Services in Mexico
- ---------------------------

     On June 7, 1995, the Secretaria de Communicaciones y Transportes, the
entity which is responsible for governing telecommunications services in Mexico,
wrote into law the method by which companies could apply for concessions and
licenses to establish and operate telecommunications services businesses within
Mexico. This was, effectively, the first step in the deregulation of the
telephone industry within Mexico. It also formalized the methods by which
companies such as ATSI may compete against Telefonos de Mexico (Telmex), the
privately owned telecommunications monopoly in Mexico. The Company, through its
subsidiary ATSI-Mexico, has applied for several licenses, and plans to apply for
additional licenses, to provide various telecommunications services within
Mexico. The Company anticipates receiving various of such licenses during
calendar year 1996 which would facilitate the expansion of services currently
being provided in Mexico, although there is no assurance that such licenses will
be received.

Operator Services in the U.S.
- -----------------------------

     The Company began providing operator services in the U.S. in August 1994.
The Federal Communications Commission (FCC) requires the filing of informational
tariffs concerning such services and requires both written and verbal
identification of the operator service provider on each call processed. The
Company believes it is in full compliance with all applicable regulations set
forth by the FCC.

     Many state regulatory bodies have imposed similar or identical regulations
upon operator services for intrastate telecommunication. The Company is
currently in the process of making the appropriate filings for these
informational tariffs in order to maintain compliance with these jurisdictional
requirements.

     For the past six years, the FCC has been considering the implementation of
a system whereby a caller could make a long distance call from any publicly
available telephone and have the call automatically routed over the long
distance telephone network of the caller's choice. The concept, called Billed
Party Preference (BPP), would necessitate that each local telephone company have
access to a data base which could match every U.S. calling card and telephone
number to a preferred long distance company and be able to route each long
distance call accordingly. The FCC first proposed adopting BPP in 1992, but
quickly received comments from local and long distance companies, as well as
other industry representatives, suggesting that the implementation and
maintenance of BPP would be extremely difficult from a technological standpoint
and would not be cost-effective. The FCC responded in June 1994 by releasing a
"Further Notice of Proposed Rulemaking" in which it expressed continued interest
in BPP and requested suggestions from the telecommunications industry for a more
cost-efficient alternative to BPP which would meet the desired results of BPP-
easy access to the caller's preferred long distance provider, increased
competition and resultant lower rates to callers.

     Implementation of BPP or a similar system could potentially have a major
impact on U.S. operator services companies such as ATSI who depend on telephones
being presubscribed, or routed, directly into their network.  BPP would take the
authority to route long distance traffic away from the telephone owner and place
it in the hands of the caller.  Both AT&T and the Regional Bell Operating
Companies have formally questioned the feasibility of BPP, and records indicate
that BPP would take from two to four years to implement should it be adopted by
the FCC.  Although the FCC continues to consider the adoption of BPP, it is not
likely to be operational in the near term.  Responses, which were due to the FCC
on August 1, 1994, were again heavily weighted against the adoption of BPP.

     The FCC again requested comment from the industry in March of 1995 on two
proposals that it had received related to BPP.  The first proposal was from the
National Association of Attorney's General, which suggested that operator
service providers modify the branding that is required at the beginning of a
call to include more specific information for obtaining access to alternative
carriers.  The second proposal was from a group of industry members including a
majority of the Regional Bell Operating Companies and the American Public
Communications Counsel (APCC).  The Company is a member of the APCC.  This
proposal suggested that reasonable rate limits be established for interstate
operator assisted services and that any operator service providers wanting to
charge rates in excess of these limits must first be required to justify its
rates to the FCC based upon its underlying costs.

     Either suggestion, if adopted, would have a negative effect on the revenues
recognized by the Company for processing domestic interstate operator assisted
long distance calls.  However, less than 33% of the Company's revenues were
generated from such calls during the year ended July 31, 1995, and this
percentage is expected to decrease in the future as the volume of international
calls continues to increase.  The Company cannot predict when and if any final
ruling will be issued by the FCC related to BPP, but the Company does not expect
any ruling on BPP to be implemented in the near term.

<PAGE>
 
     Changes in certain regulations may potentially preclude or impair the
Company's ability to provide operator services within certain jurisdictions.
The Company does not foresee any such changes, however, it cannot predict
whether such changes may occur.  Therefore, the Company cannot estimate the
impact of such changes upon its operator services in the event of any such
change.

                    AMERICAN TELESOURCE INTERNATIONAL INC.

                            1996 STOCK OPTION PLAN


  1. PURPOSE.  The purpose of this Plan is to promote the interest of American
     -------                                                                  
Telesource International Inc. (the "Company") and its shareholders by providing
an effective means to attract, retain and increase the commitment of certain
individuals and to provide such individuals with additional incentive to
contribute to the success of the Company.

  2. ELIGIBILITY.  Options may be granted under the Plan to directors and
     -----------                                                         
employees of, and advisors and consultants to, the Company, or of any parent or
subsidiary of the Company (if any) provided, however, in the case of consultants
or advisors, that such grant be in consideration of bona fide services rendered
by such consultant or advisor and such services not be in connection with the
offer or sale of securities in a capital-raising transaction.  The Committee
(defined below) shall select from such eligible class the individuals to whom
Options shall be granted from time to time.

  3. ADMINISTRATION OF THE PLAN.  The Plan shall be administered by a Committee
     --------------------------                                                
consisting of at least two outside directors (the "Committee").  No member of
the Committee shall have been, during the one-year period prior to service as an
administrator of the Plan, nor shall be, during service as an administrator,
granted or awarded options, rights, or equity securities under the Plan or under
any other plan of the Company or its affiliates except as permitted in Section
                                                                       -------
5(F) of the Plan or Rule 16b-3 ("Rule 16b-3") under the Securities Exchange Act
- ----                                                                           
of 1934, as amended (the "Exchange Act").  A quorum of such Committee shall
consist of a majority of the members of such Committee, or as may be otherwise
provided in the Company's bylaws.  The Committee shall hold meetings at such
times and places and conduct its business at such meetings as it may determine,
subject to any express provisions of the Company's bylaws.  Acts of a majority
of the Committee members attending at a meeting at which a quorum is present, or
such acts as are reduced to or approved in writing by the majority of the
members of the Committee, shall be the valid acts of the Committee.  The
Committee shall from time to time in its discretion determine which individuals
shall be granted Options, the amount of shares covered by such Options, and
certain other specific terms and conditions of such Options subject to the terms
and conditions contained herein, including outside director Options as set forth
in Section 5(F).
   ------------ 

     The Committee shall have the sole authority and power, subject to the
express provisions and conditions hereof, to construe this Plan and the Options
granted hereunder, and to adopt, prescribe, amend, and rescind rules and
regulations relating to this Plan, and to make all determinations necessary or
advisable for administering this Plan.  The Committee shall also have the
authority and power to modify any provision of this Plan to render the Plan
consistent with any amendments to Rule 16b-3 or Form S-8 of the Securities Act
of 1933, as amended (the "Securities Act"), including amendments which permit
the grant of Options on terms which are less restrictive than the terms set
forth herein.  The interpretation by the Committee of any provision of this Plan
with respect to any incentive stock option granted hereunder shall be in
accordance with section 422 of the Internal Revenue Code of 1986 and the
regulations issued thereunder, as amended from time to time (the "Internal
Revenue Code"), in order that the incentive stock options granted hereunder
("Incentive Stock Options") shall constitute "incentive stock options" within
the meaning of section 422 of the Internal Revenue Code.  Options granted under
the Plan which are not intended to be Incentive Stock Options are referred to
herein as "Nonqualified Stock Options."  The term "Options" as used herein shall
refer to Incentive Stock Options and Nonqualified Stock Options, either
collectively or without distinction.  The interpretation and construction by the
Committee, if any, of any provisions of the Plan or of any Option

                                 Appendix A - 1
<PAGE>
 
granted hereunder shall be final and conclusive.  No member of the Committee
shall be liable for any action or determination made in good faith with respect
to the Plan or any Option granted hereunder.

  4. SHARES SUBJECT TO THE PLAN.  Subject to the provisions of Section 6, the
     --------------------------                                ---------     
number of shares subject to Options granted hereunder shall not exceed 4,000,000
shares of the Company's authorized but unissued or reacquired Common Stock (the
"Common Stock").  Such number of shares shall be subject to adjustment as
provided in Section 6 (e.g., such number shall be adjusted to 2,000,000 shares
            ---------                                                         
in the event the proposed one-for-two reverse stock split of the Company's
Common Stock approved by the Board of Directors in June 1996 is effected).

     Shares that by reason of the expiration, termination, cancellation or
surrender of an Option are no longer subject to purchase pursuant to an Option
granted under the Plan (other than by reason of exercise of such Option) may be
reoptioned hereunder.

  5. TERMS AND CONDITIONS.
     -------------------- 

     (A) OPTION PRICE.  Each Option shall state the number of shares that may be
         ------------                                                           
purchased thereunder, shall expressly designate such Option as an Incentive
Stock Option or a Nonqualified Stock Option, and shall state the option price
per share (the "Option Price") which shall be paid in the manner specified in
this Section 5(A) in order to exercise such Option.  The Option Price shall not
     ------------                                                              
be less than 100% of the fair market value of the shares on the day the Option
is granted with respect to any Incentive Stock Option granted hereunder, and not
less than 100% of the fair market value of the shares on the date the Option is
granted with respect to any Nonqualified Stock Option.

         For purposes of the Plan, the fair market value per share of the Common
Stock on any date shall be deemed to be the closing price of the Common Stock on
the principal national securities exchange on which the Common Stock is then
listed or admitted to trading, if the Common Stock is then listed or admitted to
trading on any national securities exchange.  The closing price shall be the
last reported sale price regular way, or, in case no such sale takes place on
such day, the average of the closing bid and asked prices regular way, as
reported by said exchange.  If the Common Stock is not then so listed on a
national securities exchange, the fair market value per share of the Common
Stock on any date shall be deemed to be the closing price (the last reported
sale price regular way) in the over-the-counter market as reported by the Nasdaq
National Market System, if the Common Stock closing price is then reported on
the Nasdaq National Market System, or, if the Common Stock closing price of the
Common Stock is not then reported by the Nasdaq National Market System, shall be
deemed to be the mean of the highest closing bid and lowest closing asked price
of the Common Stock in the over-the-counter market as reported by the National
Association of Securities Dealers Automated Quotation System ("Nasdaq") or, if
the Common Stock is not then quoted by Nasdaq, as furnished by any member of the
National Association of Securities Dealers, Inc. selected from time to time by
the Company for that purpose.  If no member of the National Association of
Securities Dealers, Inc. furnishes quotes with respect to the Common Stock of
the Company, such fair market value shall be determined by resolution of the
Committee.  Notwithstanding the foregoing provisions of this Section 5(A), if
                                                             ------------    
the Committee shall at any time determine that it is impracticable to apply the
foregoing methods of determining fair market value, the Committee is empowered
to adopt other reasonable methods for such purpose.  The Committee may, if it
deems it appropriate, engage the services of an independent qualified expert or
experts to appraise the value of the Common Stock.

         Options under the Plan may be exercised by payment of the Option Price
in cash or, if the Common Stock is then registered under the Exchange Act and is
then traded on Nasdaq or one or more securities exchanges, by delivery of the
equivalent fair market value of Common Stock or by a "cashless exercise"
procedure in which an Optionee is permitted to exercise an Option by arranging
with the Company and his or her broker to deliver the appropriate Option Price
from the concurrent market sale of the acquired shares, or a combination of the
foregoing (subject to the discretion of the Committee). An employee's

                                 Appendix A - 2
<PAGE>
 
withholding tax due upon exercise of a Nonqualified Stock Option may be
satisfied either by a cash payment or the retention from the exercise of a
number of shares of Common Stock with a fair market value equal to the required
withholding tax, as the Committee may permit.  For Optionees who are subject to
the reporting and other provisions of Section 16 under the Exchange Act (except
as may otherwise be permitted by the Committee, subject to compliance with Rule
16b-3), the election of a partial cash settlement of an Option in order to
satisfy the tax withholding requirement upon exercise of a Nonqualified Stock
Option may be made only during a ten-day "window" period each fiscal quarter
beginning on the third business day following the date of release of the
Company's financial data for the quarter and ending on the twelfth business day
following such date, and shall be subject to the approval of the Committee.

         In addition, with respect to the exercise of any Nonqualified Stock
Option, the Committee (or an authorized representative) shall advise the
Optionee, upon receipt of notice of intent to exercise such Option, of the
income tax withholding consequences to such Optionee of such exercise, the
amount of the appropriate withholding tax and any other payments due by reason
thereof.  Such Optionee must satisfy all of the preceding payment requirements
in order to receive stock upon exercise of such Option.

     (B) OPTION PERIOD.  Any Options granted pursuant to this Plan must be
         -------------                                                    
granted within ten years from the date the Plan was adopted by the Board of
Directors of the Company (____________, 1996).

         Each Option shall state the date upon which it is granted.  Each Option
shall be exercisable during such period as is provided under the terms of the
Option, but in no event shall an Option be exercisable after the expiration of
ten years from the date of grant.  Except in the case of death or disability,
Incentive Stock Options may be exercised within three months (or for such
shorter period as may be specified in the particular Option) after termination
of employment to the extent such Options were exercisable at the date of
termination, and Nonqualified Stock Options may be exercised after termination
of employment or other service to the Company for such period as may be
specified in the particular Option.  In the event of the disability of an
Optionee, Incentive Stock Options may be exercised for up to one year after
disability of the Optionee, to the extent exercisable prior to the date of
disability.  Nonqualified Stock Options may be exercised following the
Optionee's death or disability and Incentive Stock Options may be exercised
following the Optionee's death by such Optionee or by his or her estate, heirs,
or devisees, as the case may be, for such period thereafter as may be specified
in the particular Option.

     (C) ASSIGNABILITY.  An Option granted pursuant to this Plan shall be
         -------------                                                   
exercisable during the Optionee's lifetime only by the Optionee and shall not be
assignable or transferable by the Optionee (except with the Committee's prior
written approval, and only in any such additional circumstances as shall not
affect the Plan's qualification with the requirements of the incentive stock
option provisions of the Internal Revenue Code, the requirements of Rule 16b-3
under the Exchange Act, or the plan eligibility requirements for the use of Form
S-8 of the Securities Act), and shall not be subject to levy, attachment or
similar process.  Upon any other attempt to transfer, assign, pledge or
otherwise dispose of Options granted under this Plan, such Options shall
immediately terminate and become null and void.

     (D) LIMIT ON 10% SHAREHOLDERS.  No Incentive Stock Option may be granted
         -------------------------                                           
under this Plan to any individual who would, immediately after the grant of such
Incentive Stock Option directly or indirectly own more than 10% of the total
combined voting power of all classes of stock of the Company or of any parent or
subsidiary corporation unless (i) such Incentive Stock Option is granted at an
Option Price not less than 110% of the fair market value of the shares on the
date the Incentive Stock Option is granted, and (ii) such Incentive Stock Option
expires on a date not later than five years from the date the Incentive Stock
Option is granted.

                                 Appendix A - 3
<PAGE>
 
     (E) LIMITS ON OPTIONS.  An individual may be granted one or more Options,
         -----------------                                                    
provided that the aggregate fair market value (determined as of the time the
Option is granted) of Common Stock for which an individual may be granted
Incentive Stock Options that are first exercisable in any calendar year (under
all stock option plans of the Company and any parent or subsidiary corporations,
if any) may not exceed $100,000.

     (F) OUTSIDE DIRECTORS OPTIONS.  Each outside director of the Company (that
         -------------------------                                             
is, each director who is not also an employee of the Company) shall be
automatically granted Nonqualified Options for 7,500 shares (3,750 shares as
adjusted for a one-for-two reverse stock split) on an annual basis on the fifth
business day following the first public announcement, filing or release of the
Company's net income for the Company's preceding fiscal year.  Such annually
awarded Options shall become exercisable in whole or in part from time to time
upon the first anniversary following the date of grant.  In addition to such
automatic annual awards, each outside director who is a member of the Company's
Board of Directors immediately following the domestication of the Company from a
corporation existing under the laws of the Province of Ontario, Canada to a
corporation existing under the laws of the State of Delaware, United States of
America, and each director who joins the Company's Board of Directors thereafter
shall receive upon such election or appointment an automatic award of
Nonqualified Options for 75,000 shares (37,500 shares as adjusted for a one-for-
two reverse stock split) of Common Stock, which shall become exercisable in four
equal annual installments (9,375 shares each as adjusted for a one-for-two
reverse stock split) on the first, second, third and fourth anniversaries of the
date of grant. All of the foregoing Options, once granted and to the extent they
have become exercisable, shall remain exercisable throughout their term,
regardless of whether the holder continues to serve as a director, and such term
shall expire on the tenth anniversary following the date of grant.  To the
extent any such Option is not yet exercisable upon termination of service, such
Option shall be terminated.  The Option Price for all such automatic awards
shall be equal to 100% of the fair market value of the covered shares of Common
Stock at the time of grant.  The provisions of this Plan regarding formula
awards to outside directors shall not be amended more than once every six months
thereafter, other than to comport with changes in the Internal Revenue Code, the
Employee Retirement Income Security Act, or the rules thereunder.

     (G) RIGHTS AS SHAREHOLDER.  An Optionee, or a transferee by will or
         ---------------------                                          
inheritance of an Option, shall have no rights with respect to any shares
covered by an Option until the date of the issuance of a stock certificate for
such shares and the recording of such issuance upon the Company's stock ledger
by its duly appointed, regular transfer agent.  No adjustment shall be made for
dividends (ordinary or extraordinary, whether in cash, securities or other
property) or distributions or other rights for which the record date is prior to
such date, except as provided in Section 6 hereof.
                                 ---------        

     (H) ADDITIONAL PROVISIONS.  The Options authorized under this Plan shall
         ---------------------                                               
contain such other provisions as the Board or Committee shall deem advisable,
including, without limitation, further restrictions upon the exercise of the
Option.  Any Incentive Stock Option shall contain such limitations and
restrictions upon the exercise of the Option as shall be necessary in order that
the Option shall be an "incentive stock option" as defined in section 422 of the
Internal Revenue Code.

     (I) COMPLIANCE WITH SECURITIES LAWS.  At the time of exercise of any
         -------------------------------                                 
Option, the Company may require the Optionee to execute any documents or take
any action which may then be necessary to comply with the Securities Act and the
rules and regulations adopted thereunder, or any other applicable federal or
state laws regulating the sale and issuance of securities, and the Company may,
if it deems necessary, include provisions in the Options to assure such
compliance.  The Company may from time to time change its requirements with
respect to enforcing compliance with federal and state securities laws,
including the request for, or insistence upon, letters of investment intent,
such requirements to be determined by the Company in its judgment as necessary
to assure compliance with said securities laws.  Such changes may be made with
respect to any particular Option or to any stock issued upon exercise thereof.

                                 Appendix A - 4
<PAGE>
 
  6. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION.  In the event of any change in
     ------------------------------------------                                
the number of issued and outstanding shares of Common Stock which results from a
stock split, reverse stock split, the payment of a stock dividend or any other
change in the capital structure of the Company, such as a merger, consolidation,
reorganization or recapitalization, the Committee shall appropriately adjust (a)
the maximum number of shares which may be issued under this Plan, (b) the number
of shares subject to each outstanding Option, and (c) the Option Price per share
thereof, so that upon exercise of the Option the Optionee shall receive the same
number of shares the Optionee would have received had the Optionee been the
holder of all shares subject to such outstanding Options immediately before the
effective date of such change in the number of issued shares of the Common Stock
of the Company.  Any such adjustment shall not result in or entitle the Optionee
to the issuance of fractional shares.  Instead, appropriate adjustments to any
such Option and, in the aggregate, all other options of the Company of the same
class (that is, Incentive Stock Options or Nonqualified Options) held by each
Optionee shall be made so that such Option and other options of the same class,
if any, held by any such Optionee cover the greatest whole number of shares of
the Common Stock which does not exceed the number of shares which would be
covered applying such adjustments in the absence of any restriction on the
issuance of fractional shares.  Any excess fractional share shall be redeemed in
cash at the then-current fair market value of the Common Stock (determined as
provided in Section 5(A) hereof) multiplied by the appropriate fraction of a
            ------------                                                    
share.

  7. TERMINATION OR AMENDMENT OF THE PLAN.  The Board of Directors may at any
     ------------------------------------                                    
time suspend, amend, or terminate this Plan, provided that, except as set forth
in Section 6 hereof, no amendment may be adopted that will change the
   ---------                                                         
requirement that the Option Price be at least a specified percentage of the fair
market value of the Common Stock or change the provisions required for
compliance with section 422 of the Internal Revenue Code, except to conform to a
change in the requirements of such law or regulations thereof.  Except as
otherwise specifically provided herein, the Board shall not, without the
approval of the shareholders of the Company, amend this Plan so as to materially
increase the benefits accruing to Optionees under the Plan, increase the
aggregate number of shares that may be issued under this Plan or materially
modify the requirements for eligibility for participation in the Plan.  No
amendment or termination of the Plan shall, without the consent of the Optionee,
alter or impair any rights or obligations under any Option previously granted
under the Plan.

with that person is a sufficient disclosure of interest in relation to any
contract or transaction so made or entered into.

5.03.     Indemnity:  Every person who at any time is or has been a director or
          ---------
officer of the Corporation or who at any time acts or has acted at the

Corporation or properly incurs or has properly incurred any liability on behalf

reason of so incurring or having so incurred such liability or by reason of so
acting or having so acted (or by reason of anything alleged to have been done,
omitted or acquiesced in by him in any such capacity or otherwise in respect of
any of the foregoing), and all appeals therefrom, if:

     (a)  he acted honestly and in good faith with a view to the best interests
          of the Corporation; and

     (b)  in the case of a criminal or administrative action or proceeding that

          believing his conduct was lawful.

Nothing in this section shall affect any other right to indemnity to which any
person may be or become entitled by contract or otherwise, and no settlement or
plea of guilty in any action or proceeding shall alone constitute evidence that
a person did not meet a condition set out in clause (a) or (b) of this section
or any corresponding condition in the Act.

5.04.     Limitation of Liability:  So long as he acts honestly and in good 
          -----------------------
faith with a view to the best interests of the Corporation, no person referred
to in the preceding section shall be liable for any damage, loss, cost or
liability sustained or incurred by the Corporation. However, nothing in this
section shall relieve any director or officer of the Corporation from the duty

liability for any breach of such duty.

holders the cheque shall be made payable to the order of all of them, unless
such joint holders direct otherwise in writing. The mailing of a cheque as
aforesaid, unless it is not paid on due presentation, shall discharge the
Corporation's liability for the dividend to the extent of the amount of the
cheque plus the amount of any tax thereon which the Corporation has properly
withheld. If any dividend cheque sent is not received by the payee, the
Corporation shall issue to such person a replacement cheque for a like amount on

remaining directors then in office, even though less than a quorum of the Board.
Any director elected in accordance with the preceding sentence shall hold office
for the remainder of the full term of the newly created directorship or for the
directorship in which the vacancy occurred, and until such director's successor
shall have been duly elected and qualified, subject to his earlier death,
disqualification, resignation or removal.  Subject to the provisions of this
Certificate, no decrease in the number of directors constituting the Board shall
shorten the term of any incumbent director.

  D. Except as otherwise provided in any resolution or resolutions of the Board
designating a series of Preferred Stock, any director may be removed from office
only by the affirmative vote of the holders of 66 2/3% or more of the combined
voting power of the then-outstanding shares of capital stock of the Company
entitled to vote at a meeting of stockholders called for that purpose, voting
together as a single class.

                                  ARTICLE VI.

                            MEETINGS OF STOCKHOLDERS

  A. Meetings of stockholders of the Company ("Stockholder Meetings") may be
held within or without the State of Delaware, as the Bylaws may provide.  Except
as otherwise provided in any resolution or resolutions of the Board designating
a series of Preferred Stock, special Stockholder Meetings may be called only by
(i) the President of the Company or (ii) the Board pursuant to a resolution
adopted by a majority of the then-authorized number of directors of the Company.
Special Stockholder Meetings may not be called by any other person or persons or
in any other manner.  Elections of directors need not be by written ballot
unless the Bylaws of the Company (the "Bylaws") shall so provide.

  B. In addition to the powers conferred on the Board by this Certificate and by
the Delaware General Corporation Law, and without limiting the generality
thereof, the Board is specifically authorized from time to time, by resolution
of the Board without additional authorization by the stockholders of the
Company, to adopt, amend or repeal the Bylaws, in such form and with such terms
as the Board may determine, including, without limiting the generality of the
foregoing, Bylaws relating to (i) regulation of the procedure for submission by
stockholders of nominations of persons to be elected to the Board, (ii)
regulation of the attendance at annual or special Stockholder Meetings by
persons other than holders of record or their proxies, and (iii) regulation of
the business that may properly be brought by a stockholder of the Company before
an annual or special meeting of stockholders of the Company.

                                  ARTICLE VII.

                              STOCKHOLDER CONSENT

  Except as otherwise provided in any resolution or resolutions of the Board
designating a series of Preferred Stock, no action that is required or permitted
to be taken by the stockholders of the Company at any annual or special meeting
of stockholders may be effected by written consent of stockholders in lieu of a
meeting of stockholders, unless the action to be effected by written consent of
stockholders and the taking of such action by such written consent have
expressly been approved in advance by the Board.

                                 ARTICLE VIII.

                            LIMITATION OF LIABILITY

  A director of the Company shall not be personally liable to the Company or its
stockholders for monetary damages for breach of fiduciary duty as a director;
provided, however, that this Article shall not eliminate or limit the liability
of a director: (i) for any breach of the director's duty of loyalty to the
Company or stockholders, (ii) for acts or omissions not in good faith or which
involve intentional misconduct or a knowing

                                 Exhibit H - 3
<PAGE>
 
violation of law, (iii) under section 174 of the Delaware General Corporation
Law, or (iv) for any transaction from which the director derived an improper
personal benefit.

  If the Delaware General Corporation Law is amended after the date of filing of
this Certificate to authorize corporate action further limiting or eliminating
the personal liability of a director, then the liability of the directors of the
Company shall be limited or eliminated to the fullest extent permitted by the
Delaware General Corporation Law, as so amended.  Any repeal or modification of
this Article by the stockholders of the Company or otherwise shall not adversely
affect any right or protection of a director of the Company existing at the time
of such repeal or modification.

                                  ARTICLE IX.

                                  SECTION 203

  The Company shall be governed by Section 203 of the Delaware General
Corporation Law.

                                   ARTICLE X.

                                INDEMNIFICATION

  The Company shall indemnify each director and officer of the Company who may
be indemnified, to the fullest extent permitted by Section 145 of the Delaware
General Corporation Law ("Section 145"), as it may be amended from time to time,
in each and every situation where the Company is obligated to make such
indemnification pursuant to Section 145.  In addition, the Company shall
indemnify each of the Company's directors and officers in each and every
situation where, under Section 145, the Company is not obligated, but is
permitted or empowered, to make such indemnification.  The Company may, in the
sole discretion of the Board, indemnify any other person who may be indemnified
pursuant to Section 145 to the extent the Board deems advisable, as permitted by
such section.  The Company shall promptly make or cause to be made any
determination which Section 145 requires.

                                  ARTICLE XI.

                        AMENDMENT OF CORPORATE DOCUMENTS

  A. Certificate.  Whenever any vote of the holders of voting shares of capital
     -----------                                                               
stock of the Company is required by law to amend, alter, repeal or rescind any
provision of this Certificate, then in addition to any affirmative vote required
by applicable law and in addition to any vote of the holders of any series of
Preferred Stock, as provided in any resolution or resolutions of the Board
designating a series of Preferred Stock, such alteration, amendment, repeal or
rescission (a "Change") of any provision of this Certificate must be approved by
at least a majority of the then-authorized number of directors and by the
affirmative vote of the holders of at least a majority of the combined voting
power of the then-outstanding voting shares of capital stock of the Company,
voting together as a single class; provided, however, that if any such Change
relates to Articles III, V, VI, VII, VIII, IX, X or to this Article XI, such
Change must also be approved by the affirmative vote of the holders of at least
66% of the combined voting power of the then-outstanding voting shares of
capital stock of the Company, voting together as a single class; provided
further, however, that the vote(s) required by the immediately preceding clause
shall not be required if such Change has been first approved by at least two-
thirds of the then-authorized number of directors.

     Subject to the provisions hereof, the Company reserves the right at any
time, and from time to time, to amend, alter, repeal or rescind any provision
contained in this Certificate in the manner now or hereafter prescribed by law,
and other provisions authorized by the laws of the State of Delaware at the time
in force may be added or inserted, in the manner now or hereafter prescribed by
law; and all rights, preferences and

                                 Exhibit H - 4
<PAGE>
 
privileges of whatsoever nature conferred upon stockholders, directors or any
other persons whomsoever by and pursuant to this Certificate in its present form
or as hereafter amended are granted subject to the rights reserved in this
article.

  B. Bylaws.  In addition to any affirmative vote required by law, any Change of
     ------                                                                     
the Bylaws may be adopted either (i) by the Board by the affirmative vote of at
least a majority of the then-authorized number of directors, or (ii) by the
stockholders by the affirmative vote of the holders of at least 66 2/3% of the
combined voting power of the then-outstanding voting shares of capital stock of
the Company, voting together as a single class.

                                  ARTICLE XII.

                                   EXISTENCE

                                RELATED PARTIES

  A. No contract or transaction between the Company and one or more of its
directors or officers, or between the Company and any other corporation,
partnership, association, or other organization in which one or more of its
directors or officers, are directors or officers, or have a financial interest,
shall be void or voidable solely for this reason, or solely because the director
or officer is present at or participates in the meeting of the Board or
committee which authorizes the contract or transaction, or solely because his or
their votes are counted for such purpose, if:

     (1) The material facts as to his relationship or interest and as to the
  contract or transaction are disclosed or are known to the Board or the
  committee, and the Board or committee in good faith authorizes the contract or
  transaction by the affirmative votes of a majority of the disinterested
  directors, even though the disinterested directors be less than a quorum; or

     (2) The material facts as to his relationship or interest and as to the
  contract or transaction are disclosed or are known to the stockholders
  entitled to vote thereon, and the contract or transaction is specifically
  approved in good faith by a vote of the stockholders; or

     (3) The contract or transaction is fair as to the Company as of the time it
  is authorized, approved or ratified, by the Board, a committee or the
  stockholders.

  B. Common or interested directors may be counted in determining the presence
of a quorum at a meeting of the Board or of a committee which authorizes the
contract or transaction.

                                  ARTICLE XIV.

question.

one or more inspectors to act at the meeting. Each inspector, before entering
upon the discharge of his or her duties, shall take and sign an oath to execute
faithfully the duties of inspector with strict impartiality and according to the
best of his or her ability.

     The inspector or inspectors so appointed or designated shall: (a) ascertain

<PAGE>
 
and (e) certify their determination of the number of shares of capital stock of
the Company represented at the meeting and such inspectors' count of all votes
and ballots.  Such certification and report shall specify such other information
as may be required by law.  In determining the validity and counting of proxies
and ballots cast at any meeting of stockholders of the Company, the inspectors
may consider such information as is permitted by applicable law.  No person who
is a candidate for an office at an election may serve as an inspector at such
election.

Conflicts Committee be dissolved once it is established nor shall the membership
of any committee, including, without limitations the Audit and Conflicts
Committee and the Executive Committee, be altered in any way if such alteration
would cause such committee to fail to meet its membership standards as set forth

is party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the Company), because
he is or was a director or officer of the Company, or, while a director or
officer of the Company, is or was serving at the written request of the Company
as a director, officer, trustee, employee or agent of or in any other capacity
with another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys, fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by him in connection with such
action, suit or proceeding if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
Company, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. The termination of any
action, suit or proceeding by judgment, order, settlement, conviction, or upon a
plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that the person did not act in good faith and in a manner which he
reasonably believed to be in or not opposed to the best interests of the
Company, and, with respect to any criminal action or proceeding, have reasonable
cause to believe that his conduct was unlawful.

     Section 8.2.  Actions by or in the Right of the Company.  The Company shall
                   -----------------------------------------

Company as a director, officer, trustee, employee or agent of or in any other
capacity with another corporation, partnership, joint venture or trust or other
enterprise, against expenses (including attorneys' fees) actually and reasonably
incurred by him in connection with the defense or settlement of such action or
suit if he acted in good faith and in a manner he reasonably believed to be in
or not opposed to the best interests of the Company and except that no
indemnification shall be made in respect to any claim, issue or matter as to
which such person shall have been adjudged to be liable to the Company unless
and only to the extent that the Court of Chancery or the court in which such
action or suit was brought shall determine upon application that, despite the
adjudication of liability but in view of all the circumstances of the case, such
person is fairly and reasonably entitled to indemnity for such expenses which
the Court of Chancery or such other court shall deem proper.

     Section 8.3.  Board Determinations.  Any indemnification under Sections 8.1
                   --------------------                                         
and 8.2 (unless ordered by a court) shall be made by the Company only as
authorized in the specific case upon a determination that indemnification of the
director, officer, employee or agent is proper in the circumstances because he
has met the applicable standard of conduct set forth in Sections 8.1 and 8.2.
Such determination shall be made (1) by the Board by a majority vote of a quorum
consisting of directors who were not parties to such action, suit or proceeding,
or (2) if such a quorum is not obtainable, or, even if obtainable, a quorum of
disinterested directors so directs, by independent legal counsel (which may be
counsel ordinarily used by, the Company) in a written opinion, or (3) by the
holders of a majority of the outstanding shares of capital stock of the Company
entitled to vote thereon.

officer of the Company in defending a civil or criminal action, suit or
proceeding shall (in the case of any action, suit or proceeding against a
director of the Company) or may (in the case of any pending threatened action,
suit or proceeding against an officer) be paid by the Company in advance of the
final disposition of such action, suit or proceeding upon receipt of an
undertaking by or on behalf of such director or officer to repay such amount if
it shall ultimately be determined that he is not entitled to be indemnified by
the Company as authorized by law or in this Article VIII.

     Section 8.5.  Nonexclusive.  The indemnification and advancement of
                   ------------                                         
expenses provided by, or granted pursuant to, this Article VIII shall not be
deemed exclusive of any other rights to which any director, officer, employee or
agent of the Company seeking indemnification or advancement of expenses may be
entitled under any other provision of there Bylaws or by the Certificate, an
agreement, a vote of stockholders or disinterested directors or otherwise, both
as to action in his official capacity and as to action in another capacity while
holding such office, and shall, unless otherwise provided when authorized or
ratified, continue as to a person who has ceased to be a director, officer,
employee or agent of the Company and shall inure to the benefit of the heirs,
executors and administrators of such a person.

     Section 8.6  Indemnification of Employees and Agents of the Company.  The
                  ------------------------------------------------------

agent of the Company to the fullest extent of the provisions of this section
with respect to the indemnification and advancement of expenses of directors and
officers of the Company.

the Company, or is or was serving at the request of the Company as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust, or other enterprise, against any liability asserted against him and
incurred by him in any such capacity or arising out of his status as such,
whether or not the Company would have the power to indemnify him against such
liability under provisions of applicable law, the Certificate or this Article
VIII.

court may allow, apply to the court to fix a fair value for the shares of any
dissenting shareholder.

written notice sent to the corporation within thirty days after receiving a
notice under subsection (28), may,

          (a)  withdraw a notice of dissent, in which case the corporation is
               deemed to consent to the withdrawal and the shareholder's full
               rights are reinstated; or

          (b)  retain a status as a claimant against the corporation, to be paid
               as soon as the corporation is lawfully able to do so or, in a
               liquidation, to be ranked subordinate to the rights of creditors
               of the corporation but in priority to its shareholders.

any of the actions referred to in subsection (1) or (2), the court may, if
satisfied that the proposed action is not in all the circumstances one that
should give rise to the rights arising under subsection (4), by order declare

                              PART II TO FORM S-4
 
                  INFORMATION NOT REQUIRED IN THE PROSPECTUS
 
ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Section 145 of the Delaware General Corporation Law ("DGCL") authorizes a
corporation to indemnify any person ("indemnitee") who was or is a party or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding (other than an action by or in the right of the corporation)
because such person is or was a director, officer, employee or agent of the
corporation, or is or was serving at the request of the corporation, in a
similar position with another corporation or entity, against expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by him in connection with such action, suit or proceeding if
he acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the corporation and, with respect to any
criminal action or proceeding, had no reasonable cause to believe his conduct
was unlawful. With respect to actions or suits by or in the right of the
corporation, however, an indemnitee who acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation is generally limited to attorneys' fees and other expenses, and no
indemnification shall be made if such person is adjudged liable to the
corporation unless and only to the extent that a court of competent jurisdiction
determines that indemnification is appropriate. Section 145 further provides
that any indemnification shall be made by the corporation only as authorized in
each specific case upon a determination by the (i) board of directors by a
majority vote of directors who were not parties to such action, suit or
proceeding even though less than a quorum, (ii) independent counsel if there are
no such disinterested directors or if such directors so direct, or (iii)
stockholders, that indemnification of the indemnitee is proper because he has
met the applicable standard of conduct. Section 145 provides that
indemnification pursuant to its provisions is not exclusive of other rights of
indemnification to which a person may be entitled under any bylaw, agreement,
vote of stockholders or disinterested directors of otherwise.

     ATSI's (upon Domestication) and ATSI Merger Corp.'s Certificate of
Incorporation and Bylaws, copies of which are filed as Exhibits to this
Registration Statement, provide, in substance, that directors and officers shall
be indemnified to the fullest extent permitted by Section 145 of the DGCL.

     ATSI's (upon Domestication) and ATSI Merger Corp.'s Certificate of
Incorporation, copies of which are filed as Exhibits to this Registration
Statement, limit the liability of directors of the Company to the Company or its
stockholders (in their capacity as directors but not in their capacity as
officers) to the fullest extent permitted by the DGCL. Specifically, directors
of the Company will not be personally liable for monetary damages for breach of
a director's fiduciary duty as a director, except for liability (i) for any
breach of the director's duty of loyalty to the Company or its stockholders,
(ii) for acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law, (iii) for unlawful payments of
dividends or unlawful stock repurchases or redemptions as provided in Section
174 of the DGCL or (iv) for any transaction from which the director derived an
improper personal benefit. The Certificate of Incorporation also provides that
if the DGCL is amended after the approval of the Amended and Restated
Certificate of incorporation also provides that if the DGCL is amended after the
approval of the Amended and Restated Certificate of incorporation to authorize
corporate action further eliminating or limiting the personal liability of
directors, then the liability of a director of the Company will be eliminated or
limited to the full extent permitted by the DGCL, as so amended.

     Each ATSI Company has entered into or intends to enter into indemnification
agreements with each of its directors and its executive officers. The
indemnification agreements provide that the Company shall indemnify these
individuals against certain liabilities (including settlements) and expenses
actually and reasonably incurred by them in connection with any threatened or
pending legal action, proceeding or investigation (other than actions brought by
or in the right of the Company) to which any of them is, or is

                                     II - 1
<PAGE>
 
threatened to be, made a party by reason of their status as a director, officer
or agent of the Company, provided that such individual acted in good faith and
in a manner he or she reasonably believed to be in or not opposed to the best
interests of the Company, and with respect to any criminal proceedings, had no
reasonable cause to believe his or her conduct was unlawful. With respect to any
action brought by or in the right of the Company, such individuals may also be
indemnified, to the extent not prohibited by applicable laws or as determined by
a court of competent jurisdiction, against expenses actually and reasonably
incurred by them in connection with such action if they acted in good faith and
in a manner they reasonably believed to be in or not opposed to the best
interests of the Company. The agreements also require indemnification of such
individuals for all reasonable expenses incurred in connection with the
successful defense of any action or claim and provide for partial
indemnification in the case of any partially successful defense.

ITEM 22.  UNDERTAKINGS

     The undersigned registrants hereby undertake:

     (a)  To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement;

          (i)  To include any prospectus required by Section 10(a)(3) of the
     Securities Act of 1933;

         (ii)  To reflect in the prospectus any facts or events arising after
     the effective date of the registration statement (or the most recent post-
     effective amendment thereof) which, individually or in the aggregate,
     represent a fundamental change in the information set forth in the
     registration statement.

                                     II - 3
<PAGE>
 
     Notwithstanding the foregoing, any increase or decrease in volume of
     securities offered (if the total dollar value of securities offered would
     not exceed that which was registered) and any deviation from the low or
     high end of the estimated maximum offering range may be reflected in the
     form of prospectus filed with the Commission pursuant to Rule 424(b) if, in
     the aggregate, the changes in volume and price represent no more than a 20
     percent change in the maximum aggregate offering price set forth in the
     "Calculation of Registration Fee" table in the effective registration
     statement.

        (iii)  To include any material information with respect to the plan of
     distribution not previously disclosed in the registration statement or any
     material change to such information in the registration statement.

     (b)  That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

     (c)  To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.

     (d)  If the registrant is a foreign private issuer, to file a post-
effective amendment to the registration statement to include any financial
statements required by Rule 3-19 of this chapter at the start of any delayed
offering or throughout a continuous offering. Financial statements and
information otherwise required by Section 10(a)(3) of the Act need not be
furnished, provided, that the registrant includes in the prospectus, by means of
a post-effective amendment, financial statements required pursuant to this
paragraph (d) and other information necessary to ensure that all other
information in the prospectus is at least as current as the date of those
financial statements. Notwithstanding the foregoing, with respect to
registration statements on Form F-3, a post-effective amendment need not be
filed to include financial statements and information required by Section
10(a)(3) of the Act or Rule 3-19 of this chapter if such financial statements
and information are contained in periodic reports filed with or furnished to the
Commission by the registrant pursuant to section 13 or section 15(d) of the
Securities Exchange Act of 1934 that are incorporated by reference in the Form 
F-3.

     (e)  to respond to requests for information that is incorporated by
reference into the prospectus pursuant to Items 4, 10(b), 11, or 13 of this
Form, within one business day of receipt of such request, and to send the
incorporated documents by first class mail or other equally prompt means. This
includes information contained in documents filed subsequent to the effective
date of the registration statement through the date of responding to the
request.

     (f)  to supply by means of a post-effective amendment all information
concerning a transaction, and the company being acquired involved therein, that
was not the subject of and included in the registration statement when it became
effective.

     (g)  that prior to any public reoffering of the securities registered
hereunder through use of a prospectus which is a part of this registration
statement, by any person or party who is deemed to be an underwriter within the
meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus
will contain the information called for by the applicable registration form with
respect to reofferings by persons who may be deemed underwriters, in addition to
the information called for by the other Items of the applicable form.

     (h)  that every prospectus (i) that is filed pursuant to paragraph (c)
immediately preceding, or (ii) that purports to meet the requirements of Section
10(a)(3) of the Act and is used in connection with an offering of securities
subject to Rule 415, will be filed as a part of an amendment to the registration
statement and will not be used until such amendment is effective, and that, for
purposes of determining any liability under the Securities Act of 1933, each
such post-effective amendment shall be deemed to be a new registration statement

                                     II - 4
<PAGE>
 
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Commission such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against liabilities
(other than the payment by the registrant of expenses incurred or paid by a
director, officer or controlling person of the registrant in the successful
defense of any action, suit or proceeding) is asserted by such director, officer
or controlling person in connection with the securities being offered, the
registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question of whether such indemnification by it is against public policy as
expressed in the Securities Act, and will be governed by the final adjudication
of such issue.

Rent as herein provided,

                                       1
<PAGE>
 
and in consideration of the other terms, provisions and covenants hereof,
Landlord hereby demises and leases to Tenant and Tenant hereby takes from
Landlord the Premises, and to HAVE AND TO HOLD the same for the Term specified
in Section 1.(e), commencing on the Commencement Date herein specified. TENANT
ACKNOWLEDGES THAT IT HAS INSPECTED THE PREMISES AND ACCEPTS THE PREMISES IN
THEIR PRESENT CONDITION AS SUITABLE FOR THE PURPOSE FOR WHICH THE PREMISES ARE
LEASED; AND FURTHER ACKNOWLEDGES, THAT NO REPRESENTATIONS AS TO THE REPAIR OF
THE PREMISES NOR PROMISES TO ALTER, REMODEL OR IMPROVE THE PREMISES HAVE BEEN
MADE BY LANDLORD EXCEPT AS SET OUT IN SECTION 12 OF THIS LEASE. If this Lease is
executed before the Premises become vacant or otherwise available and ready for
occupancy by Tenant, including the Landlord's completion of the Tenant finish
out required under Section 12 of this Lease, or if any present tenant or
occupant of the Premises holds over and Landlord cannot acquire and deliver to
Tenant possession of the Premises prior to the date above recited as the
Commencement Date of this lease, Landlord shall not be deemed to be in default
hereunder or responsible for any claims, damages or liabilities in connection
therewith, or by reason thereof. Tenant agrees to accept possession of the
Premises at such time as Landlord is able to tender the same to Tenant, in which
event, the date of tender of the Premises by the Landlord to Tenant shall be the
Commencement Date unless the delay in tender is due to Tenant's actions, in
which event the Commencement Date shall not be altered; and Landlord hereby
waives payment of Rent covering any period prior to the tendering of possession
to Tenant hereunder. Tenant's failure to occupy the Premises when tendered by
Landlord upon completion of the Landlord's improvements shall not delay the
Commencement Date.


     3.   Base Rent: Tenant agrees to pay monthly as Base Rent during the term 
          ---------                                                     
of this Lease the sum of money set forth in Section 1.(f) of this Lease, which
amount shall be payable to Landlord at the address shown in section 30. The
initial monthly installment of Base Rent shall be due and payable upon the
execution of this Lease and future monthly installments shall be due and payable
on or before the first day of each calendar month succeeding the Rental
Commencement Date during the term of this Lease; provided, if the Commencement
Date should be a date other than the first day of a calendar month, the monthly
rental set forth above shall be prorated to the end of that calendar month, and
all succeeding installments of Rent shall be payable on or before the first day
of each succeeding calendar month during the term of this Lease. Tenant shall
pay, as additional rent, all other sums due under this Lease. Unless otherwise
specifically allowed by the hereinafter enumerated terms of this Lease, the
Tenant shall pay the Rent and other sums payable hereunder without notice or
demand and without regard to any counterclaim, right or set off, deduction or
defense Tenant may have against Landlord, and without abatement, suspension,
deferment, diminution or reduction; and, the obligations of Tenant hereunder
shall not be in any way affected or reduced by any restriction, prevention or
curtailment of or interference with any use of the Project, Premises, or any
part thereof for any reason whatsoever.


     4.   Common Expenses.  "Common Expenses," as used herein, shall consist of 
          ----------------                                           
certain operating expenses of the Project, and shall consist of expenditures by
Landlord to keep and maintain all facilities in operation at the beginning of
the Term of the Lease and such additional facilities in subsequent years as may
be determined by Landlord to be necessary or beneficial for the operation of the
Project. All operating expenses shall be determined in accordance with generally
accepted cash or accrual (at Landlord's option) accounting principles which
shall be consistently applied. The Term "Common Expenses," as used herein, shall
mean all expenses, costs, and disbursements (but not the cost of capital
improvements originally installed in the Project by Landlord, nor specific costs
especially billed to and paid by specific tenants) of every kind and nature
which Landlord shall pay or become obligated to pay because of or in connection
with the ownership and operation of the Project, including, but not limited to,
the following:

          (a)  Cost of all utilities for the Project not separately metered to
     the tenants.

          (b)  Cost of providing those Landlord services to the Project
     prescribed in Paragraph 18 hereof.

          (c)  Lighting, planting, cleaning, policing, inspecting, landscaping
     and repairing the Common Areas.

          (d)  Pest control expenditures attributable to the Project.

          (e)  Except as otherwise provided in this Lease, cost of repairs
     (structural and nonstructural) and general maintenance of the Project
     (excluding repairs and general maintenance paid by proceeds of insurance or
     by Tenant or other third parties, and alterations attributable solely to
     other tenants of the Project).

          (f)  Heating, ventilation and air conditioning maintenance contract.

          (g)  A reasonable management fee for managing the Project.

          Such common expenses shall not include taxes and insurance. Prior to 
January 1 of each calendar year or at any tine during Tenant's occupancy, 
Landlord reserves the right to provide an estimate of Common Expenses for the 
forthcoming calendar year, whereupon, upon receipt of Notice by Landlord, Tenant
shall pay an amount equal to the product of Tenant's Proportionate Share 
multiplied by Landlord's estimate of Common

                                       2
<PAGE>
 
Expenses for the forthcoming calendar year.

          By June 1 of each calendar year during Tenant's occupancy, or as soon
thereafter as possible, or upon initial occupancy of the Premises by Tenant, for
the remainder of the calendar year in which Tenant first occupies the Premises.
Landlord shall furnish to Tenant a statement of Landlord's actual Common
Expenses for the previous calendar year. A lump sum payment or credit (which
payment or credit shall be deemed a payment of or credit against the Rent
payable hereunder for all purposes) will be made from Tenant to Landlord in the
case of a payment, and from Landlord to Tenant, in the case of a credit, within
thirty (30) days of the delivery of such statement, equal to the difference
between the product of Tenant's Proportionate Share times Landlord's actual
Common Expenses for the previous calendar year minus the amount already paid by
Tenant pursuant to the immediately preceding paragraph. The effect of this
reconciliation payment is that Tenant will pay during the Term of this Lease,
its Proportionate Share of Common Expenses.


     5.   Security Deposit.  The Security Deposit set forth in 1.(g) above 
          ----------------
shall be held by Landlord for the performance of Tenant's covenants and
obligations under this Lease, it being expressly understood that the deposit
shall not be considered an advance payment of rental or a measure of Landlord's
damage in case of default by Tenant. Upon the occurrence of any event of default
by Tenant or breach by Tenant of Tenant's covenants under this Lease, Landlord
may, from time to time, without prejudice to any other remedy, use the Security
Deposit to the extent necessary to make good any arrears of rent, or to repair
any damage or injury, or pay any expense or liability incurred by Landlord as a
result of the event of default or breach of covenant, and any remaining balance
of the Security Deposit shall be returned by Landlord to Tenant upon termination
of this Lease. If any portion of the Security Deposit is so used or applied,
Tenant shall upon ten days written notice from Landlord, deposit with Landlord
by cash or cashier's check an amount sufficient to restore the Security Deposit
to its original amount.


     6.   Holding Over.  In the event that Tenant does not vacate the Premises 
          ------------
upon the expiration or termination of this Lease, Tenant shall be a tenant at
will for the holdover period and all of the terms and provisions of this Lease
shall be applicable during that period, except that Tenant shall pay Landlord as
Base Rent for the period of such holdover an amount equal to two times the Rent
which would have been payable by Tenant had the holdover period been a part of
the original term of this Lease. Tenant agrees to vacate and deliver the
Premises to Landlord upon Tenant's receipt of notice from Landlord to vacate.
The Rent payable during the holdover period shall be payable to Landlord on
demand. No holding over by Tenant, whether with or without the consent of
Landlord, shall operate to extend the term of this Lease.


     7.   Use.  Tenant warrants and represents to Landlord that the Premises
          ---
shall be used and occupied only for the purpose as set forth in Section 1.(h).
Tenant shall occupy the Premises, conduct its business and control its agents,
employees, invitees and visitors in such a manner as is lawful, reputable and
will not create a nuisance. Tenant shall not permit any operation which emits
any odor or matter which intrudes into other portions of the Project, use any
apparatus or machine which makes undue noise or causes vibration in any portion
of the Project or otherwise interfere with, annoy or disturb any other lessee in
its normal business operations or Landlord in its management of the Project.
Tenant shall neither permit any waste on the Premises nor allow the Premises to
be used in any way which would, in the opinion of Landlord, be extra hazardous
on account of fire or which would in any way increase or render void the fire
insurance on the Project. If at any time during the term of this Lease the State
Board of Insurance or other insurance authority or imposes an additional penalty
or surcharge in Landlord's insurance premiums because of Tenant's original or
subsequent placement or use of storage racks or bins, method of storage or
nature of Tenant's inventory or any other act of Tenant, Tenant agrees to pay as
additional rent the increase in Landlord's insurance premiums.


     8.   Signs.  No sign of any type or description shall be erected, placed or
          -----
painted in or about the Premises or project except those signs submitted to
Landlord in writing and approved by Landlord in writing, and which signs are in
conformance with Landlord's sign criteria established for the project. Tenant
shall remove such signs at the termination of this Lease without defacing the
building.


     9.   Compliance with Laws, Rules and Regulations.  Tenant, at Tenant's sole
          -------------------------------------------
cost and expense, shall comply with all laws, ordinances, orders, rules and
regulations of state, federal, municipal or other agencies or bodies having
jurisdiction over use, condition and occupancy of the Premises. Tenant will
comply with the Rules and Regulations of the project adopted by Landlord which 
are set forth on a Exhibit D attached to this Lease. Landlord shall have the 
right at all times to change and amend the Rules and Regulations in any 
reasonable manner as may be deemed advisable for the safety, care, cleanliness, 
preservation of good order and operation or use of the Project or the Premises. 
All changes and amendments to the Rules and Regulations of the Project will be 
sent by Landlord to Tenant in writing and shall thereafter be carried out and 
observed by Tenant. In addition to the foregoing, Landlord shall bare the 
continuing obligation during the Lease Term to ensure that the Premises and the 
Project are at all times in compliance with all laws, regulations  and 
ordinances including the provisions of the Americans with Disabilities Act.

                                       3

     10.  Warranty of Possession.  Landlord warrants that it has the right and
          ----------------------                                              
authority to execute this Lease, and Tenant, upon payment of the required rents
and subject to the terms, conditions, covenants and agreements contained in this
Lease, shall have possession of the Premises during the full term of this Lease
as well as any extension or renewal thereof. Landlord shall not be responsible
for the acts or omissions of any other lessee or third party that may interfere
with Tenant's use and enjoyment of the Premises.


     11.   Inspection.  Landlord or its authorized agents shall at any and all
           ----------                                                         
reasonable times have the right to enter the Premises to inspect the same, to
supply janitorial service or any other service to be provided by Landlord, to
show the Premises to prospective purchasers or lessees, and to alter, improve or
repair the Premises or any other portion of the Project. Tenant hereby waives
any claim for damages for injury or inconvenience to or interference with
Tenant's business, any loss of occupancy or use of the Premises, and any other
loss occasioned thereby. Landlord shall at all times have and retain a key with
which to unlock all of the doors in, upon and about the Premises. Tenant shall
not change Landlord's lock system or in any other manner prohibit Landlord from
entering the Premises, except as may be provided in this Lease or Landlord's
written Rules and Regulations. Landlord shall have the right to use any and all
means which Landlord may deem proper to open any door in an emergency without
liability therefore. Notwithstanding the above, Tenant may secure the storage
and computer room within the Demised Premises.


     12.  Landlord's Improvements.  Landlord shall construct the finish-out
          -----------------------                                      
work (hereinafter "Tenants Improvements") pursuant to the Final Working
Drawings, now or to be hereafter attached as Exhibit "C" pursuant to the terms
and conditions of Landlord's Workletter attached as Exhibit "B".

          In the event of any delay in the completion of Tenant's Improvements
caused by Tenant, Landlord shall not be liable for any damage caused thereby. In
the event Tenant takes occupancy prior to the completion of Landlord's
Improvements, Tenant shall provide uninterrupted access to the Premises to
Landlord, its employees, agents, representatives and governmental inspectors at
all reasonable times.

          Upon Landlord and Tenant's approval in writing of the final plans and
specifications of Tenant's Improvements, including the improvements described in
Exhibit "C", Landlord shall promptly commence work on such improvements and
shall thereafter diligently pursue the completion thereof. The time period for
completion of the Tenant's Improvements shall be extended by any changes in the
work requested by Tenant, any delays beyond Landlord's reasonable control in
securing materials for the improvements, or permits from governmental
authorities having jurisdiction over Landlord's work, and any delays caused by
Tenant or Tenant's contractors. Tenant shall coordinate its work schedule for
improvements being constructed by Tenant and Tenant's "move in" activities with
the Landlord so as not to unreasonably interfere with the completion of the
Tenant's Improvements.


     13.  Utilities and Services.
          ---------------------- 

          (a)  Utility Services.  Landlord shall provide or cause to be provided
               ----------------                                                 
     the mains, conduits and other facilities necessary to supply water, gas,
     electricity, telephone service and sewage service to the Leased Premises.
     Tenant shall, however, be responsible, at its expense, to make provisions
     for connecting or hooking up to such utilities, directly with the
     appropriate utility company furnishing same.

          (b)  Responsibility for Charges.  Landlord, subject to Section C, 
               -------------------------- 
     below, shall bear the cost of water sewage services provided to the Leased
     Premises. Tenant shall promptly pay all charges and deposits for
     electricity, gas, and telephone service and all other utilities (except for
     water and sewage) furnished to the Leased Premises. Landlord may, if it so
     elects, furnish one or more utility services to Tenant, and in such event,
     Tenant shall purchase the use of such services as are tendered by Landlord,
     and shall pay on demand the rates established therefor by Landlord which
     shall not exceed the rates which would be charged for the same services if
     furnished to Tenant directly by the local public utility furnishing the
     same to the public at large. Landlord may at any time discontinue
     furnishing any such service without obligation to Tenant other than to
     connect the Leased Premises to the public utility, if any, furnishing such
     service.

          (c)  Landlord's Services.  Landlord shall provide routine maintenance,
               -------------------   
     painting and electric lighting service for all Common Areas and special
     service areas of the Property in the manner and to the extent deemed by
     Landlord to be standard. Landlord may, in its sole discretion, provide
     additional services not enumerated herein.

          (d)  Excessive Utility Consumption.  Tenant shall pay all water and
               -----------------------------
     sewage costs occasioned by high consumption for such services, as
     determined by Landlord, including (without limitation) the cost of
     installing, servicing and maintaining any special or additional inside or
     outside lines, meters or submeters, or the cost of any other equipment
     necessary to increase the amount or type of water and sewage services
     available to the Leased Premises.

          (e)  Window Coverings.  Landlord may (but shall not be obligated to) 
               ----------------
     furnish and install window coverings on all exterior windows to maintain a 
     uniform exterior appearance. Tenant shall not

                                       4
<PAGE>
 
     remove or replace these window coverings or install any other window
     covering which would affect the exterior appearance of the Building. Tenant
     may install lined or unlined over draperies on the interior sides of the
     Landlord furnished window coverings for interior appearance or to reduce
     light transmission, provided such over draperies do not (in Landlord's
     determination) affect the exterior appearance of the Building or affect the
     operation of the Building's heating, ventilating and air conditioning
     systems.

          (f)  No Liability.  Landlord shall not be liable for any interruption
               ------------                                                    
     whatsoever in utility service not furnished by it, nor for interruptions in
     utility service furnished by it which are due to fire, accident, strikes,
     acts of God, riot, civil commotion, terrorist act, national emergency,
     shortages of labor or materials, or other causes beyond the control of
     Landlord or in order to make alterations, repairs or improvements.
     Moreover, Landlord shall not be liable for any interruption of such utility
     services which continues during any reasonable period necessary to restore
     such service upon the occurrence of any of the foregoing conditions.
     Failure by Landlord to any extent to provide any service of Landlord
     specified herein or any other services not specified, or any cessation
     thereof, shall not render Landlord liable in any respect for damages to
     either person or property, be construed as an eviction of Tenant, work an
     abatement of rent or relieve Tenant form fulfillment of any covenant in
     this Lease. If any of the equipment or machinery necessary or useful for
     provision of any utility services, and for which Landlord is responsible,
     breaks down, or for any cause ceased to function properly, Landlord shall
     use reasonable diligence to repair the same promptly, but Tenant shall have
     no claim for rebate of rent or damages on account of any interruption in
     service occasioned from the repairs. Notwithstanding the above, if
     electrical service is disrupted for a continuous period of at least five
     (5) full days because of Landlord's negligence, Tenant may provide Landlord
     with written notice of such fact, afterwhich Landlord shall have forty-
     eight (48) hours to restore service to the Premises. In the event
     electrical service is not restored within said fortyeight (48) hour
     period, Tenant, at Tenant's sole option, may terminate this Lease.

          (g)  Theft or Burglary.  Landlord shall not be liable to Tenant for 
               ----------------- 
     losses to Tenant's property or personal injury caused by criminal acts or
     entry by unauthorized persons into the Leased Premises or the Property.


     14.  Taxes.
          ----- 

          (a)  The maximum amount of taxes levied or assessed against the real
     property of which the Premises are a part during any one real estate tax
     year to be paid by Landlord shall be a total of the actual calendar year
     1994 real estate tax expense for the Project. If, in any real estate tax
     year during the term hereof or any renewal or extension of this Lease, the
     ad valorem taxes levied or assessed against the Premises for such tax year
     shall exceed such specified sum, Tenant shall pay to Landlord upon demand
     within thirty (30) days the amount for such excess. In the event the
     Premises constitute a portion of a multiple occupancy building, Tenant
     agrees to pay to Landlord upon demand the amount of Tenant's proportionate
     share of such excess (with respect to taxes lawfully levied or assessed
     against the building and grounds, parking areas, driveways, and alleys
     around the said building), such share to be calculated by Landlord as .044
                                                                           ----

          (b)  Tenant shall pay before delinquent all taxes, assessments, and
     other charges that are levied against Tenant's personal property installed
     or located in or on the Premises that become due and payable during the
     Term hereof.


    15.   Landlord's Repairs.  Landlord shall, at its expense, keep and 
          ------------------                                           
maintain the roof, foundation, and the structural soundness of the exterior
walls of the building in good repair, reasonable wear and tear excepted.
Landlord expressly reserves the right to use all exterior walls and the roof of
the building of which the Premises are a part. Tenant shall repair and pay for
any damage caused by the negligence of Tenant, or Tenant's employees, agents or
invitees, or caused by Tenant's default hereunder. The term "walls," as used
herein, shall not include windows, glass and plate glass, stairways, doors or
special storefronts. Tenant shall immediately give Landlord written notice of
defect or need for repairs, after which Landlord shall have a reasonable
opportunity to repair same or cure such defect. Landlord's liability hereunder
shall be limited to the cost of such repairs or curing such defect. Landlord
shall not be liable for damage to Tenant's Improvements, inventory and equipment
within the Premises. In the event the Premises have air conditioning and heating
systems, or fire sprinkler systems installed therein on the date of this Lease,
then Landlord represents that on the Commencement Date of this Lease, such air
conditioning and heating systems and sprinkler systems shall be in good
operating condition; provided, however, that during the Term of this Lease,
Tenant shall, at its own cost and expenses, maintain such systems in good 
operating condition, shall make all necessary repairs and replacements, and upon
termination of this Lease, shall deliver such system to Landlord in good 
operating condition.


     16.  Tenant's Repairs.  Tenant shall, at its own cost and expense, keep and
          ----------------
maintain (including periodic cleaning and preventative maintenance) all other 
parts of the Premises in good repair and condition, including, but not limited 
to, windows, glass and plate glass, doors, any special storefront, interior 
walls and finish work, stairways, floors and floor covering, downspouts and 
gutters, dock boards, plumbing work and fixtures, all lighting and all 
electrical systems and the HVAC systems within the Premises and shall take good 
care of the Premises and

                                       5
<PAGE>
 
its fixtures; and Tenant shall not permit the Premises to suffer waste. Tenant
shall further be responsible for all damages to the exterior and other portions
of the building of which the Premises are a part, which are caused by Tenant,
Tenant's employees, invitees and guests. Landlord shall make available to Tenant
any and all warranties and guaranties of construction and materials of the
improvements on the Premises and the building in which the same are situated,
and the equipment situated therein. Tenant shall not be obligated to repair any
damage caused by fire, tornado or other casualty covered by items set forth
under the extended coverage provisions of Landlord's fire insurance policy.
Tenant shall not be permitted to dump or drain any garbage, waste water, refuse,
liquids or any other materials directly onto the parking lot surface surrounding
the building in which the Premises are situated or anywhere in the Project
without the prior written consent of Landlord. Tenant shall also be responsible
for any damage to the parking lot caused by front-end loaders or other vehicles
and equipment utilized in connection with Tenant's use of the Premises. If
Tenant fails to make the repairs or replacements promptly as required herein,
Landlord may, at its option, make the repairs and replacements and the
reasonable cost of such repairs and replacements shall be charged to Tenant as
additional rent and shall become due and payable by Tenant within ten (10) days
from receipt of Landlord's invoice. Costs incurred under this paragraph are the
total responsibility of Tenant and do not constitute common expenses under
Paragraph 4.


     17.  Alterations.  Tenant shall not make any alterations, additions or
          -----------                                                      
improvements to the Premises without the prior written consent of Landlord.
Tenant may, without the consent of Landlord, but at its own cost and expense and
in a good and workmanlike manner, make such minor alterations, additions or
improvements, or erect, remove or alter such partitions, or erect such shelves,
bins, machinery and trade fixtures as Tenant may deem advisable without altering
the basic character of the building or improvements and without overloading or
damaging such building or improvements; and, in each case, complying with all
applicable governmental laws, ordinances, regulations, and other requirements.
At the termination of this Lease, Tenant shall, if Landlord so elects, remove
all alterations, additions, improvements and partitions erected by Tenant and
restore the Premises to their original condition; otherwise, such improvements
shall be delivered up to the Landlord with the Premises. All shelves, bins,
machinery and trade fixtures installed by Tenant may be removed by Tenant at the
termination of this Lease if Tenant so elects, and shall be removed if required
by Landlord. All such removals and restoration shall be accomplished in a good
workmanlike manner so as not to damage the primary structure or structural
qualities of the buildings and other improvements situated on the Premises. All
roof penetrations and roof alterations of any kind which are approved by
Landlord, shall be performed by the Landlord's roofing contractor at Tenant's
sole cost and expense.

          Prior to making any alterations or repairs to the Premises which will
involve the alteration or removal of plumbing, electrical wiring, air
conditioning, heating or ventilation systems, or the fire sprinkler system,
Tenant shall furnish Landlord with a set of the plans and specifications for the
alterations or repairs and shall not commence any such work without Landlord's
express written approval.


     18.  Services by the Landlord.  Landlord shall furnish the Tenant, while 
          ------------------------                                     
occupying the Premises, cold water at those points of supply provided for the
general use of the tenants in the building, exterior security lights (as
determined necessary by Landlord) and exterior janitorial service for the
building so that the parking lot, sidewalks, exterior sides of exterior glass,
and landscaping of the Project are maintained in a clean, neat and orderly
fashion. Tenant shall be responsible for all interior janitorial services and
for placing trash in the exterior dumpsters or other trash receptacles serving
the Project in accordance with reasonable rules and regulations promulgated from
time to time by Landlord.

          Landlord, at Landlord's option, may provide general area security or
guard services from time to time for the Project, in which event, the cost of
such service attributable to the Project shall be considered a Common Expense.
Tenant, at its sole cost and expense, shall provide whatever security or alarm
services or systems which Tenant deems necessary and/or appropriate for the
protection of the Premises and contents thereof. In no event shall the Landlord
be responsible for loss or damage to any of the Tenant's property, including all
furniture, fixtures, equipment and inventory, even if Landlord has provided
security service. Tenant may, with Landlord's prior written approval, re-key the
Premises' locks as deemed necessary by Tenant from time to time, provided Tenant
uses the locksmith specified by Landlord and complies with all of Landlord's
Rules and Regulations concerning keys and locks.


     19.  Common Areas.  All parking areas, sidewalks, driveways, landscaped 
          ------------                                                       
areas (inclusive of sprinkler systems), and other common areas located on the
real property on which the Project is located, and such other areas and
facilities that the Landlord shall from time to time designate as being for the
mutual use of itself and the Tenant, their customers and employees, shall be 
known as the "Common Areas." Tenant, its employees, customers and invitees shall
have the nonexclusive right to use the Common Areas, together with the Landlord 
and the other Tenants of the building, their customers, employees and guests, 
and subject to such rules and regulations governing the use of the Common Areas 
as the Landlord may from time to time prescribe, such rules specifically 
including, but not limited to, parking rules. The Tenant shall not solicit any 
business within the Common Areas or use the Common Areas for storage without the
prior written consent of the Landlord or take any action which would interfere 
with the rights of other persons to use the Common Areas. Landlord may 
temporarily close any part of the Common Areas for such period of time as is 
necessary to make repairs or alterations to the Common Areas or the improvements
located in the Project of which the Premises are a part.

                                       6
<PAGE>
 
          Tenant shall, at all times during the Term of this Lease, have in
common with the Landlord and all other tenants and guests of the Project, the
nonexclusive use of the parking areas located within the Project; provided,
however, the Landlord shall have the right to designate portions of the parking
areas as reserved for covered parking for specific tenants of the Project.
Landlord may make, modify and enforce rules and regulations relating to the
parking of automobiles, trucks, trailers and other vehicles on the Project, and
the entrances, exits and traffic lanes of parking areas. The Tenant, its
employees, customers and guests, will abide by such rules and regulations.


     20.  Fire & Casualty Damage.
          ---------------------- 

          (a)  Substantial Destruction - If the Leased Premises should be 
               -----------------------                               
     totally destroyed by fire or other casualty, or if the Premises, as
     determined by Landlord, should be damaged so that rebuilding cannot
     reasonably be completed within one hundred twenty (120) working days after
     the date of written notification by Tenant to Landlord of the destruction,
     this Lease shall terminate and the Rent shall be abated for the unexpired
     portion of the Lease, effective as of the date of the written notification.

          (b)  Partial Destruction - If the Premises should be partially damaged
               -------------------                                       
     by fire or other casualty, and rebuilding or repairs can reasonably be
     completed within one hundred twenty (120) working days from the date of
     written notification by Tenant to Landlord of the destruction, this Lease
     shall not terminate, and Landlord shall at its sole risk and expense
     proceed with reasonable diligence to rebuild or repair the building or
     other improvements to substantially the same condition in which they
     existed prior to the damage. If the Premises to be rebuilt or repaired are
     untenantable in whole or in part following the damage, and the damage or
     destruction was not caused or contributed to by act or negligence of
     Tenant, its agents, employees, invitees or those for whom Tenant is
     responsible, the Rent payable under this Lease during the period for which
     the Premises are untenantable shall be adjusted to such an extent as may be
     fair and reasonable under the circumstances.

     In the event that Landlord fails to complete the necessary repairs or
     rebuilding within one hundred twenty (120) working days from the date of
     written notification by Tenant to Landlord of the destruction, Tenant may
     at its option terminate this Lease by delivering written notice of
     termination to Landlord, whereupon all rights and obligations under this
     Lease shall cease to exist. Notwithstanding anything herein to the
     contrary, in the event the holder of any indebtedness secured by a mortgage
     or deed of trust covering the Project of which the Premises are a part
     requires that the insurance proceeds be applied to such indebtedness, then
     Landlord shall have the right to terminate this Lease by delivering written
     notice of termination to Tenant whereupon all rights and obligations
     hereunder shall cease and terminate.


     21.  Insurance.
          --------- 

          (a)  Landlord shall at all times during the term of this Lease
     maintain a policy or policies of insurance with the premiums paid in
     advance, issued by and binding upon some solvent insurance company,
     insuring the building against all risk of direct physical loss in an amount
     equal to at least eighty percent of the full replacement cost of the
     building structure and its improvements as of the date of the loss;
     provided, Landlord shall not be obligated in any way or manner to insure
     any personal property (including, but not limited to, any furniture,
     machinery, goods or supplies) of Tenant upon or within the Leased Premises,
     any fixtures installed or paid for by Tenant upon or within the Premises
     or any improvements which Tenant may construct on the Premises. Tenant
     shall have no right in or claim to the proceeds of any policy of insurance
     maintained by Landlord even if the cost of such insurance is home by Tenant
     as set forth in Paragraph 4 (e).

          (b)  The maximum amount of insurance premiums for fire and extended
     coverage insurance in the Project during any one calendar year which is to
     be paid by the Landlord shall be a total of the actual calendar year 1994
     insurance expense for the Project. If, in any one calendar year during the
     term or any renewal hereof, the fire and extended coverage insurance
     premiums assessed against the building and improvements of which the
     Premises are a part exceed such specified sum, Tenant shall pay to the
     Landlord upon demand the amount of such excess. In the event the Premises
     constitute a portion of a multiple occupancy building, Tenant agrees to pay
     the Landlord upon demand the amount of Tenant's proportionate share of such
     excess as calculated by Landlord.

          (c)  Tenant at all times during the Lease term shall, at its own 
     expense, keep in full force and effect comprehensive general liability
     insurance with "personal injury" coverage and contractual liability
     coverage, with minimum limits of $1,000,000.00 on account of bodily
     injuries to, or death of, one or more than one person as the result of any
     one accident or occurrence and $500,000.00 on account of damage to
     property. Tenant shall also carry insurance against fire and such other
     risks as are from time to time included in Standard All-Risk Insurance
     (including coverage against vandalism and malicious mischief) for the full
     insurable value of Tenant's merchandise, trade fixtures, furnishings, wall
     covering, carpeting, drapes, equipment and all items of personal property
     of Tenant located on or in the Leased Premises. Landlord shall be a named
     additional insured on said policy. All insurance policies or duly executed
     certificates for the same required to be carried by Tenant under this
     Lease, together with satisfactory

                                       7
<PAGE>
 
     evidence of the payment of the premium thereof, shall be deposited with
     Landlord on the date Tenant first occupies the Leased Premises and upon
     renewals of such policies not less than fifteen (15) days prior to the
     expiration of the term of such coverage. All insurance required to be
     carried by Tenant under this Lease shall be in form and content, and
     written by insurers acceptable to Landlord, in its sole discretion. If
     Tenant shall fail to comply with any of the requirements contained relating
     to insurance, Landlord may obtain such insurance and Tenant shall pay to
     Landlord, on demand as additional rent hereunder, the premium cost thereof.

          (d)  Tenant, at its sole cost and expense, shall insure all tenant
     improvements excluding improvements done by Landlord prior to occupancy and
     outlined in EXHIBITS "B" and "C" and property located on the Premises.
     Landlord shall in no way be responsible to insure or restore any of
     Tenant's personal property or improvements; and Tenant hereby releases and
     discharges Landlord from any and all such claims and demands.

          (e)  All policies of insurance shall be written by insurance company
     or companies qualified to do business in the State of Texas which are
     acceptable to the Landlord, and all such policies shall contain
     endorsements providing for ten (10) days' notice of termination or
     cancellation to the Landlord, and its mortgagee, if any.

          (f)  Fifteen (15) days prior to the expiration of any policy of
     insurance required to be provided by Tenant under the terms of this Lease,
     the Tenant shall deliver to Landlord a Certificate of Insurance evidencing
     the renewal of each such policy of insurance. Any certificate of insurance
     required hereunder shall provide that at least ten (10) days' written
     notice of any change in or cancellation of the insurance shall be given by
     the insurance company to the Landlord and Landlord's mortgagee, if any. The
     Tenant shall promptly pay the premiums for any renewal of insurance.

          (g)  In compliance with the insurance company requirements, Tenant
     shall not violate or permit to be violated any of the conditions or
     provisions of any such policy or policies of insurance, and Tenant shall
     perform and satisfy the requirements of the company writing such policies.

          (h)  Upon the failure at any time of the Tenant to obtain and deliver
     to the Landlord or the Landlord's mortgagee, any certificate of insurance
     or duplicate policy of insurance required by this Lease, together with the
     appropriate receipts indicating that the policy's premiums have been paid
     at least fifteen (15) days before the expiration of the insurance policies,
     if any, or to pay the premiums therefor, the Landlord shall be at liberty
     from time to time, and as often as such failure should occur, to procure
     such insurance and to pay the premiums therefor as are commercially
     reasonable, and, any and all sums paid for insurance by the Landlord shall
     be and become and are hereby declared to be additional rental under the
     terms of the Lease, which sum shall be immediately due and payable to
     Landlord.



     22.  Waiver of Subrogation.  Anything in this Lease to the contrary
          ---------------------                                         
notwithstanding, Landlord and Tenant hereby waive and release each other of and
from any and all right of recovery, claim, action or cause of action, against
each other, their agents, officers and employees, for any loss or damage that
may occur to the Premises, improvements to the building of which the Premises
are a part, or personal property within the building, by reason of fire or the
elements, regardless of cause or origin, including negligence of Landlord or
Tenant and their agents, officers and employees. Landlord and Tenant agree
immediately to give their respective insurance companies which have issued
policies of insurance covering all risk of direct physical loss, written notice
of the terms of the mutual waivers contained in this section, and to have the
insurance policies properly endorsed, if necessary, to prevent the invalidation
of the insurance coverages by reason of the mutual waivers.


     23.  Hold Harmless.  Landlord shall not be liable to Tenant or Tenant's
          -------------   
employees, agents, patrons or visitors, or to any other person whomsoever for
any injury to person or damage to property on or about the Premises, caused by
the negligence or misconduct of Tenant, its agents, servants or employees, or of
any other person entering upon the Premises under express or implied invitation
of Tenant, or caused by the buildings and improvements located on the Project
becoming out of repair, or caused by leakage of gas, oil, water or steam or by
electricity emanating from the Premises, drain or sewer stoppages or backups, or
due to any cause whatsoever; and, Tenant agrees to indemnify Landlord and hold
it harmless from any loss, expense or claims, including attorneys' fees,
arising out of any such damage or injury, except that any injury to person or
damage to property caused by the negligence of Landlord or by the failure of 
Landlord to repair and maintain that part of the Premises which Landlord is 
obligated to repair and maintain, if any, after the receipt of written notice 
from Tenant of needed repairs or of defects shall be the liability of Landlord 
and not of Tenant; and, Landlord agrees to indemnify Tenant and hold it harmless
from any and all loss, expenses or claims, including attorneys' fees, arising 
out of such damage or injury. Tenant shall procure and maintain throughout the 
Term of this Lease a policy or policies of insurance, at its sole cost and
expense, insuring both Landlord and Tenant against all claims, demands or
actions arising out of or in connection with Tenant's use or occupancy of the
Premises, or by the condition of the Premises, the limits of such policy or
policies to be consistent with the limits of the liability policies described in
Paragraph 21 of this Lease.

                                       8
<PAGE>
 
     24.  Assignment and Subletting.  Tenant shall not have the right to 
          -------------------------
assign this Lease or to sublet the whole or any part of the Premises without the
prior written consent of Landlord. Notwithstanding any permitted assignment or
subletting, Tenant shall at all times remain fully responsible and liable for
the payment of the Rent herein specified and for compliance with all of its
other obligations under the terms, provisions and covenants of this Lease. Upon
the occurrence of an "event of default," as hereinafter defined, if the
Premises or any part thereof are then assigned or sublet, Landlord, in addition
to any other remedies herein provided or provided by law, may, at its option,
collect directly from such assignee or subtenant all rents becoming due to
Tenant under such assignment or sublease and apply any such Rent against any
sums due to it by Tenant hereunder; and, no such collection shall be construed
to constitute a novation or a release of Tenant from the further performance of
its obligations hereunder. Landlord shall have the right to assign any of its
rights under this Lease.



     25.  Condemnation.
          ------------ 

          (a)  Substantial Taking - If all or a substantial part of the 
               ------------------  
     Premises are taken for any public or quasi-public use under any
     governmental law, ordinance or regulation, or by right of eminent domain or
     by purchase in lieu thereof, and the taking would prevent or materially
     interfere with the use of the Premises for the purpose for which it is then
     being used, this Lease shall terminate and the Rent shall be abated during
     the unexpired portion of this Lease effective on the date physical
     possession is taken by the condemning authority. Tenant shall have no claim
     to the condemnation award or proceeds in lieu thereof.

          (b)  Partial Taking - If a portion of the Premises shall be taken for 
               --------------                                               
     any public or quasi-public use under any governmental law, ordinance or
     regulation, or by right of eminent domain or by purchase in lieu thereof,
     and this Lease is not terminated as provided in Section 24.(a) above, or if
     necessary access to parking for the Premises is materially affected by such
     action, Tenant shall have the right to terminate this Lease and the Rent
     and other obligations for the unexpired portions of this Lease shall be
     abated. If Tenant does not terminate this Lease, Landlord shall at
     Landlord's sole risk and expense, promptly restore and reconstruct the
     building and other improvements in the Premises to the extent necessary to
     make it reasonably tenantable. The Rent payable under this Lease during the
     unexpired portion of the term shall be adjusted to such an extent as may be
     fair and reasonable under the circumstances. Tenant shall have no claim to
     the condemnation award or proceeds in lieu thereof.


     26.  Default and Remedies.
          -------------------- 

          (a)  Default by Tenant - The following shall be deemed to be events of
               -----------------                                                
     default by Tenant under this Lease:

          (1) Tenant shall fail to pay when due any installment of Rent or any
          other payment required pursuant to this Lease; and the failure is not
          cured within five (5) days after written notice to Tenant;

          (2) Tenant shall abandon, desert, vacate, or cease operation in any
          substantial portion of the Premises and discontinue paying rental;

          (3) Tenant shall fail to comply with any term, provision or covenant
          of this Lease, other than the payment of Rent, and the failure is not
          cured within ten (10) days after written notice to Tenant:

          (4) Tenant shall file a petition or be adjudged bankrupt or insolvent
          under any applicable federal or state bankruptcy or insolvency law or
          admit that it cannot meet its financial obligations as they become
          due; or a receiver or trustee shall be appointed for all or
          substantially all of the assets of Tenant; or Tenant shall make a
          transfer in fraud of creditors or shall make an assignment for the
          benefit of creditors; or

          (5) Tenant shall do or permit to be done any act which results in a
          lien being filed against the Premises or the building and/or project
          of which the Premises are a part.

          (b)  Remedies for Tenant's Default - Upon the occurrence of any event
               -----------------------------                                   
     of default set forth in this Lease, Landlord shall have the option to
     pursue any one or more of the remedies set forth herein without any notice 
     or demand.

          (1) Landlord may enter upon and take possession of the Premises, by
          picking or changing locks if necessary, and lock out, expel or remove
          Tenant and any other person who may be occupying all or any part of
          the Premises without being liable for any claim for damages, and relet
          the Premises on behalf of Tenant and receive the rent directly by
          reason of the reletting. Tenant agrees to pay landlord on demand any
          deficiency that may arise by reason of any reletting of the Premises:
          further, Tenant agrees to reimburse Landlord for any reasonable
          expenditures made by it in order to relet the Premises, including, but
          not limited to, remodeling and repair costs.

                                       9
<PAGE>
 
          (2) Landlord may enter upon the Premises, by picking or changing locks
          if necessary, without being liable for any claim for damages, and do
          whatever Tenant is obligated to do under the terms of this Lease.
          Tenant agrees to reimburse Landlord on demand for any expenses which
          Landlord may incur in effecting compliance with Tenant's obligations
          under this Lease; further, Tenant agrees that Landlord shall not be
          liable for any damages resulting to Tenant from effecting compliance
          with Tenant's obligations under this Lease unless caused by the
          negligence of Landlord or otherwise.

          (3) Landlord may terminate this Lease, in which event Tenant shall
          immediately surrender the Premises to Landlord, and if Tenant fails to
          surrender the Premises, Landlord may, without prejudice to any other
          remedy which it may have for possession or arrearages in rent, enter
          upon and take possession of the Premises, by picking or changing locks
          if necessary, and lock out, expel or remove Tenant and any other
          person who may be occupying all or any part of the Premises without
          being liable for any claim for damages. Tenant agrees to pay on demand
          the amount of all loss and damage which Landlord may suffer by reason
          of the termination of this Lease under this section, whether through
          inability to relet the Premises on satisfactory terms or otherwise.
          Notwithstanding any other remedy set forth in this Lease, in the event
          Landlord has made rent concessions of any type or character, or waived
          any Rent, and Tenant fails to take possession of the Premises on the
          commencement or completion date or otherwise defaults at any time
          during the term of this Lease, the rent concessions, including any
          waived Rent, shall be canceled and the amount of the Rent or other
          rent concessions shall be due and payable immediately as if no rent
          concessions or waiver of any Rent had ever been granted. A rent
          concession or waiver of the Rent shall not relieve Tenant of any
          obligation to pay any other charge due and payable under this Lease
          including without limitation any sum due under Section 3.
          Notwithstanding anything contained in this Lease to the contrary, this
          Lease may be terminated by Landlord only by mailing or delivering
          written notice of such termination to Tenant, and no other act or
          omission of Landlord shall be construed as a termination of this
          Lease.

          (c)  Repetitive Default - Should Tenant be in default for the same 
               ------------------                                            
     cause three (3) or more times during the Term of this Lease, regardless of
     whether Tenant has cured previous defaults, Landlord may elect at its
     option to declare the term hereof ended, re-enter the Premises and take
     possession thereof, and remove all persons therefrom, and Tenant shall have
     no further claim therein or hereunder.

          (d)  Fees and Costs - If on account of any breach or default by 
               --------------                                   
     Tenant in Tenant's obligations hereunder, it shall become necessary for
     Landlord to employ (or contract with) an attorney or other professional to
     enforce or defend any of Landlord's rights or remedies hereunder, Tenant
     agrees to pay any reasonable fees and costs incurred by Landlord in such
     connection.

          (e)  Remedies Cumulative - No reference to any specific right or 
               -------------------
     remedy in this Lease shall preclude Landlord from exercising any other
     right or from having any other remedy or from maintaining any action or
     proceeding to which it may otherwise be entitled at law or in equity (or
     both). Landlord's failure to insist upon a strict performance of any
     covenant of this Lease or to exercise any option or right herein contained
     shall not be a waiver or relinquishment for the future of such covenant,
     right or option, or the continuance of the failure of Tenant, but the same
     shall remain in full force and effect.

          (f)  Remedies of Tenant - In the event of any default by Landlord, 
               ------------------
     Tenant's exclusive remedy shall be an action for damages (Tenant hereby
     waiving the benefit of any laws granting Tenant a lien upon the property of
     Landlord and/or upon rental due Landlord), but prior to any such action
     Tenant shall give Landlord written notice specifying such default with
     particularity, and Landlord shall thereupon have thirty (30) days plus such
     additional reasonable period as may be required in the exercise by Landlord
     of due diligence in which to cure any such default. Unless and until
     Landlord fails thereof. All obligations of Landlord hereunder shall be
     construed as covenants, not conditions; and all such obligations shall be
     binding upon Landlord only during the period of Landlord's possession of
     the Shopping Center and not thereafter.

     27.  Liens.
          ----- 

          (a)  Landlord's Lien - As security for payment of Rent, damage and all
               ---------------                                       
     other payments required to be made by this Lease, Tenant hereby grants to
     Landlord a lien upon all property of Tenant now or subsequently located
     upon the Premises. Notwithstanding, Landlord hereby agrees to subordinate
     any statutory or contractual landlord's lien to any security interest in
     Tenant's property, now existing or hereafter granted by Tenant. In this
     regard, Landlord agrees to execute any and all documents which may
     reasonably be necessary to accomplish such subordination. If Tenant
     abandons or vacates any substantial portion of the Premises or is in
     default in the payment of any rentals, damages or other payments required
     to be made by this Lease or is in default of any other provision of this
     Lease. Landlord may enter upon the Premises, by picking or changing locks
     if necessary, and take possession of all or any part of the personal
     property, and may sell all or any part of the personal property at a public
     or private sale, in one or successive sales, with or without notice, to the
     highest bidder for cash, and, on behalf of Tenant, sell and convey all or
     part of the personal property to the highest bidder, delivering to the
     hightest bidder all of Tenant's title and interest in the personal property
     sold. The proceeds of the sale of the personal

                                       10

     attorney's fees, and then toward the payment of all sums then due by Tenant
     to Landlord under the terms of this Lease. Any excess remaining shall be
     paid to Tenant or any other person entitled thereto by law.

          (b)  Mortgages - Tenant accepts this Lease subject and subordinate 
               ---------                                                      
     to any recorded mortgage or deed of trust lien presently existing or
     hereafter created upon the building or Project and to all existing recorded
     restrictions, covenants, easements and agreements with respect to the
     building or Project. Landlord is hereby irrevocably vested with full power
     and authority to subordinate Tenant's interest under this Lease to any
     first mortgage or deed of trust lien hereafter placed on the Premises, and
     Tenant agrees upon demand to execute additional instruments subordinating
     this Lease as Landlord may require. If the interests of Landlord under this
     Lease shall be transferred by reason of foreclosure or other proceedings
     for enforcement of any first mortgage or deed of trust on the Premises,
     Tenant shall be bound to the transferee (sometimes called the "Purchaser")
     at the option of the Purchaser, under the terms, covenants and conditions
     of this Lease for the balance of the term remaining, including any
     extensions or renewals, with the same force and effect as if the Purchaser
     were Landlord under this Lease, and, if requested by the Purchaser, Tenant
     agrees to attorn to the Purchaser, including the first mortgagee under any
     such mortgage if it be the Purchaser, as its Landlord.

          (c)  Mechanic's liens - Tenant shall have no authority, express or 
               ----------------                                              
     implied, to create or place any lien or encumbrance of any kind or nature
     whatsoever upon, or in any manner to bind the interest of Landlord in the
     Premises or to charge the rentals payable hereunder for any claim in favor
     of any person dealing with Tenant, including those who may furnish
     materials or perform labor for any construction or repairs, and each such
     claim shall affect and each such lien shall attach to, if at all, only the
     leasehold interest granted to Tenant by this instrument. Tenant covenants
     and agrees that it will pay or cause to be paid all sums legally due and
     payable by it on account of any labor performed or materials furnished in
     connection with any work performed on the Premises on which any lien is or
     can be validly and legally asserted against its leasehold interest in the
     Premises or the improvements thereon, and that it will save and hold
     Landlord harmless from any and all loss, cost or expense based on or
     arising out of asserted claims or liens against the leasehold estate or
     against the rights, title and interest of the Landlord in the Premises or
     under the terms of this Lease.

               Nothing contained in this Lease shall constitute the consent or
     the request of the Landlord, expressed or implied, for the performance of
     any labor or the furnishing of any materials or other property in respect
     to the Leased Premises, or any part thereof, nor is the Tenant given any
     authority to contract for or commit the renting of any services or the
     furnishing of any materials or other properties so as to permit the making
     of any claims against the Landlord.

          (d)  Estoppel Certificates - Tenant agrees to furnish, from time to 
               --------------------- 
     time, within ten (10) days after receipt of a request from Landlord or
     Landlord's mortgagee, a statement certifying, if applicable and to the
     extent true, the following: Tenant is in possession of the Premises; the
     Premises are acceptable; the Lease is in full force and effect; the Lease
     is unmodified; Tenant claims no present charge, lien, or claim of offset
     against rent; the rent is paid for the current month, but is not prepaid
     for more than one month and will not be prepaid for more than one month in
     advance; there is no existing default by reason of some act or omission by
     Landlord; and such other matters as may be reasonably required by Landlord
     or Landlord's mortgagee. Tenant's failure to deliver such statement, in
     addition to being a default under this Lease, shall be deemed to establish
     conclusively that this Lease is in full force and effect except as declared
     by Landlord, that Landlord is not in default of any of its obligations
     under this Lease, and that Landlord has not received more than one month's
     rent in advance.


     28.  Laws and Governmental Regulations.  Tenant agrees to comply promptly 
          ---------------------------------                          
with all laws, rules and orders of the federal, state and municipal governments
and all other departments applicable to the Premises and to comply promptly with
the requirements of the Board of Fire Underwriters. This lease shall be governed

          generation, storage or sale, any substances designated as, or
          containing components designated as hazardous, dangerous, toxic or

          Substances;

               (v)    Comply with minimum levels, standards or other performance
          standards or requirements which may be set forth or established for
          certain Hazardous Substances (if minimum standards or levels are
          applicable to Hazardous Substances present on the Premises, such
          levels or standards shall be established by an on-site inspection by
          the appropriate governmental authorities and shall be set forth in an
          addendum to this Lease); and

               (vi)   Comply with all applicable governmental rules, regulations

     terms, provisions or covenants of this Lease. Failure by Landlord to
     enforce one or more of the remedies provided upon an event of default shall

     pay Landlord's costs of collection, including reasonable attorney's fees
     for the services of the attorney, whether suit is actually filed or not.

               ----------
     benefit of Landlord and Tenant and their respective heirs, personal
     representatives, successors and assigns. It is hereby covenanted and agreed

     comprising Landlord shall be liable for any deficiency. In no event shall

     nor any person or entity comprising Landlord other than its interest in the
     Project as herein expressly provided.

                    AMERICAN TELESOURCE INTERNATIONAL INC.

                            1996 STOCK OPTION PLAN


     1.  PURPOSE.  The purpose of this Plan is to promote the interest of 
         -------                           
American Telesource International Inc. (the "Company") and its shareholders by
providing an effective means to attract, retain and increase the commitment of
certain individuals and to provide such individuals with additional incentive to
contribute to the success of the Company.
 
     2.  ELIGIBILITY.  Options may be granted under the Plan to directors and
         -----------                                                         
employees of, and advisors and consultants to, the Company, or of any parent or
subsidiary of the Company (if any) provided, however, in the case of consultants
or advisors, that such grant be in consideration of bona fide services rendered
by such consultant or advisor and such services not be in connection with the
offer or sale of securities in a capital-raising transaction.  The Committee
(defined below) shall select from such eligible class the individuals to whom
Options shall be granted from time to time.
 
     3.  ADMINISTRATION OF THE PLAN.  The Plan shall be administered by a 
         --------------------------
Committee consisting of at least two outside directors (the "Committee"). No
member of the Committee shall have been, during the one-year period prior to
service as an administrator of the Plan, nor shall be, during service as an
administrator, granted or awarded options, rights, or equity securities under
the Plan or under any other plan of the Company or its affiliates except as
permitted in Section 5(F) of the Plan or Rule 16b-3 ("Rule 16b-3") under
             ------------
the Securities Exchange Act of 1934, as amended (the "Exchange Act"). A quorum
of such Committee shall consist of a majority of the members of such Committee,
or as may be otherwise provided in the Company's bylaws. The Committee shall
hold meetings at such times and places and conduct its business at such meetings
as it may determine, subject to any express provisions of the Company's bylaws.
Acts of a majority of the Committee members attending at a meeting at which a
quorum is present, or such acts as are reduced to or approved in writing by the
majority of the members of the Committee, shall be the valid acts of the
Committee. The Committee shall from time to time in its discretion determine
which individuals shall be granted Options, the amount of shares covered by such
Options, and certain other specific terms and conditions of such Options subject
to the terms and conditions contained herein, including outside director Options
as set forth in Section 5(F).
                ------------ 

                                
     The Committee shall have the sole authority and power, subject to the
express provisions and conditions hereof, to construe this Plan and the Options
granted hereunder, and to adopt, prescribe, amend, and rescind rules and
regulations relating to this Plan, and to make all determinations necessary or
advisable for administering this Plan. The Committee shall also have the
authority and power to modify any provision of this Plan to render the Plan
consistent with any amendments to Rule 16b-3 or Form S-8 of the Securities Act
of 1933, as amended (the "Securities Act"), including amendments which permit
the grant of Options on terms which are less restrictive than the terms set
forth herein. The interpretation by the Committee of any provision of this Plan
with respect to any incentive stock option granted hereunder shall be in
accordance with section 422 of the Internal Revenue Code of 1986 and the
regulations issued thereunder, as amended from time to time (the "Internal
Revenue Code"), in order that the incentive stock options granted hereunder
("Incentive Stock Options") shall constitute "incentive stock options" within
the meaning of section 422 of the Internal Revenue Code. Options granted under
the Plan which are not intended to be Incentive Stock Options are referred to
herein as "Nonqualified Stock Options." The term "Options" as used herein shall
refer to Incentive Stock Options and Nonqualified Stock Options, either
collectively or without distinction. The interpretation and construction by the
Committee, if any, of any provisions of the Plan or of any Option 

                                Appendix A - 1
<PAGE>
 
granted hereunder shall be final and conclusive. No member of the Committee
shall be liable for any action or determination made in good faith with respect
to the Plan or any Option granted hereunder.

     4.  SHARES SUBJECT TO THE PLAN. Subject to the provisions of Section 6, the
         --------------------------                               ---------     
number of shares subject to Options granted hereunder shall not exceed 4,000,000
shares of the Company's authorized but unissued or reacquired Common Stock (the
"Common Stock"). Such number of shares shall be subject to adjustment as
provided in Section 6 (e.g., such number shall be adjusted to 2,000,000 shares
            ---------                                        
in the event the proposed one-for-two reverse stock split of the Company's
Common Stock approved by the Board of Directors in June 1996 is effected).

     Shares that by reason of the expiration, termination, cancellation or
surrender of an Option are no longer subject to purchase pursuant to an Option
granted under the Plan (other than by reason of exercise of such Option) may be
reoptioned hereunder.

     5.  TERMS AND CONDITIONS.
         --------------------  

         (A) OPTION PRICE.  Each Option shall state the number of shares that
             ------------
may be purchased thereunder, shall expressly designate such Option as an
Incentive Stock Option or a Nonqualified Stock Option, and shall state the
option price per share (the "Option Price") which shall be paid in the manner
specified in this Section 5(A) in order to exercise such Option. The Option
                  ------------ 
Price shall not be less than 100% of the fair market value of the shares on the
day the Option is granted with respect to any Incentive Stock Option granted
hereunder, and not less than 100% of the fair market value of the shares on the
date the Option is granted with respect to any Nonqualified Stock Option.

          For purposes of the Plan, the fair market value per share of the
Common Stock on any date shall be deemed to be the closing price of the Common
Stock on the principal national securities exchange on which the Common Stock is
then listed or admitted to trading, if the Common Stock is then listed or
admitted to trading on any national securities exchange. The closing price shall
be the last reported sale price regular way, or, in case no such sale takes
place on such day, the average of the closing bid and asked prices regular way,
as reported by said exchange. If the Common Stock is not then so listed on a
national securities exchange, the fair market value per share of the Common
Stock on any date shall be deemed to be the closing price (the last reported
sale price regular way) in the over-the-counter market as reported by the Nasdaq
National Market System, if the Common Stock closing price is then reported on
the Nasdaq National Market System, or, if the Common Stock closing price of the
Common Stock is not then reported by the Nasdaq National Market System, shall be
deemed to be the mean of the highest closing bid and lowest closing asked price
of the Common Stock in the over-the-counter market as reported by the National
Association of Securities Dealers Automated Quotation System ("Nasdaq") or, if
the Common Stock is not then quoted by Nasdaq, as furnished by any member of the
National Association of Securities Dealers, Inc. selected from time to time by
the Company for that purpose. If no member of the National Association of
Securities Dealers, Inc. furnishes quotes with respect to the Common Stock of
the Company, such fair market value shall be determined by resolution of the
Committee. Notwithstanding the foregoing provisions of this Section 5(A), if the
                                                            ------------
Committee shall at any time determine that it is impracticable to apply the
foregoing methods of determining fair market value, the Committee is empowered
to adopt other reasonable methods for such purpose. The Committee may, if it
deems it appropriate, engage the services of an independent qualified expert or
experts to appraise the value of the Common Stock.

          Options under the Plan may be exercised by payment of the Option Price
in cash or, if the Common Stock is then registered under the Exchange Act and is
then traded on Nasdaq or one or more securities exchanges, by delivery of the
equivalent fair market value of Common Stock or by a "cashless exercise"
procedure in which an Optionee is permitted to exercise an Option by arranging
with the Company and his or her broker to deliver the appropriate Option Price
from the concurrent market sale of the acquired shares, or a combination of the
foregoing (subject to the discretion of the Committee). An employee's

                                Appendix A - 2
<PAGE>
 
withholding tax due upon exercise of a Nonqualified Stock Option may be
satisfied either by a cash payment or the retention from the exercise of a
number of shares of Common Stock with a fair market value equal to the required
withholding tax, as the Committee may permit. For Optionees who are subject to
the reporting and other provisions of Section 16 under the Exchange Act (except
as may otherwise be permitted by the Committee, subject to compliance with Rule
16b-3), the election of a partial cash settlement of an Option in order to
satisfy the tax withholding requirement upon exercise of a Nonqualified Stock
Option may be made only during a ten-day "window" period each fiscal quarter
beginning on the third business day following the date of release of the
Company's financial data for the quarter and ending on the twelfth business day
following such date, and shall be subject to the approval of the Committee.

          In addition, with respect to the exercise of any Nonqualified Stock
Option, the Committee (or an authorized representative) shall advise the
Optionee, upon receipt of notice of intent to exercise such Option, of the
income tax withholding consequences to such Optionee of such exercise, the
amount of the appropriate withholding tax and any other payments due by reason
thereof. Such Optionee must satisfy all of the preceding payment requirements in
order to receive stock upon exercise of such Option.

     (B)  OPTION PERIOD.  Any Options granted pursuant to this Plan must be
          ------------- 
granted within ten years from the date the Plan was adopted by the Board of
Directors of the Company (____________, 1996).

          Each Option shall state the date upon which it is granted. Each Option
shall be exercisable during such period as is provided under the terms of the
Option, but in no event shall an Option be exercisable after the expiration of
ten years from the date of grant. Except in the case of death or disability,
Incentive Stock Options may be exercised within three months (or for such
shorter period as may be specified in the particular Option) after termination
of employment to the extent such Options were exercisable at the date of
termination, and Nonqualified Stock Options may be exercised after termination
of employment or other service to the Company for such period as may be
specified in the particular Option. In the event of the disability of an
Optionee, Incentive Stock Options may be exercised for up to one year after
disability of the Optionee, to the extent exercisable prior to the date of
disability. Nonqualified Stock Options may be exercised following the Optionee's
death or disability and Incentive Stock Options may be exercised following the
Optionee's death by such Optionee or by his or her estate, heirs, or devisees,
as the case may be, for such period thereafter as may be specified in the
particular Option.

     (C)  ASSIGNABILITY.  An Option granted pursuant to this Plan shall be
          -------------  
exercisable during the Optionee's lifetime only by the Optionee and shall not be
assignable or transferable by the Optionee (except with the Committee's prior
written approval, and only in any such additional circumstances as shall not
affect the Plan's qualification with the requirements of the incentive stock
option provisions of the Internal Revenue Code, the requirements of Rule 16b-3
under the Exchange Act, or the plan eligibility requirements for the use of Form
S-8 of the Securities Act), and shall not be subject to levy, attachment or
similar process. Upon any other attempt to transfer, assign, pledge or otherwise
dispose of Options granted under this Plan, such Options shall immediately
terminate and become null and void.

     (D)  LIMIT ON 10% SHAREHOLDERS.  No Incentive Stock Option may be granted
          -------------------------
under this Plan to any individual who would, immediately after the grant of such
Incentive Stock Option directly or indirectly own more than 10% of the total
combined voting power of all classes of stock of the Company or of any parent or
subsidiary corporation unless (i) such Incentive Stock Option is granted at an
Option Price not less than 110% of the fair market value of the shares on the
date the Incentive Stock Option is granted, and (ii) such Incentive Stock Option
expires on a date not later than five years from the date the Incentive Stock
Option is granted.

                                Appendix A - 3
<PAGE>
 
     (E)  LIMITS ON OPTIONS.  An individual may be granted one or more Options,
          -----------------
provided that the aggregate fair market value (determined as of the time the
Option is granted) of Common Stock for which an individual may be granted
Incentive Stock Options that are first exercisable in any calendar year (under
all stock option plans of the Company and any parent or subsidiary corporations,
if any) may not exceed $100,000.

     (F)  OUTSIDE DIRECTORS OPTIONS.  Each outside director of the Company (that
          -------------------------
is, each director who is not also an employee of the Company) shall be
automatically granted Nonqualified Options for 7,500 shares (3,750 shares as
adjusted for a one-for-two reverse stock split) on an annual basis on the fifth
business day following the first public announcement, filing or release of the
Company's net income for the Company's preceding fiscal year. Such annually
awarded Options shall become exercisable in whole or in part from time to time
upon the first anniversary following the date of grant. In addition to such
automatic annual awards, each outside director who is a member of the Company's
Board of Directors immediately following the domestication of the Company from a
corporation existing under the laws of the Province of Ontario, Canada to a
corporation existing under the laws of the State of Delaware, United States of
America, and each director who joins the Company's Board of Directors thereafter
shall receive upon such election or appointment an automatic award of
Nonqualified Options for 75,000 shares (37,500 shares as adjusted for a one-for-
two reverse stock split) of Common Stock, which shall become exercisable in four
equal annual installments (9,375 shares each as adjusted for a one-for-two
reverse stock split) on the first, second, third and fourth anniversaries of the
date of grant. All of the foregoing Options, once granted and to the extent they
have become exercisable, shall remain exercisable throughout their term,
regardless of whether the holder continues to serve as a director, and such term
shall expire on the tenth anniversary following the date of grant. To the extent
any such Option is not yet exercisable upon termination of service, such Option
shall be terminated. The Option Price for all such automatic awards shall be
equal to 100% of the fair market value of the covered shares of Common Stock at
the time of grant. The provisions of this Plan regarding formula awards to
outside directors shall not be amended more than once every six months
thereafter, other than to comport with changes in the Internal Revenue Code, the
Employee Retirement Income Security Act, or the rules thereunder.

     (G)   RIGHTS AS SHAREHOLDER.  An Optionee, or a transferee by will or
           --------------------- 
inheritance of an Option, shall have no rights with respect to any shares
covered by an Option until the date of the issuance of a stock certificate for
such shares and the recording of such issuance upon the Company's stock ledger
by its duly appointed, regular transfer agent. No adjustment shall be made for
dividends (ordinary or extraordinary, whether in cash, securities or other
property) or distributions or other rights for which the record date is prior to
such date, except as provided in Section 6 hereof.
                                 ---------

     (H)   ADDITIONAL PROVISIONS.  The Options authorized under this Plan shall
           --------------------- 
contain such other provisions as the Board or Committee shall deem advisable,
including, without limitation, further restrictions upon the exercise of the
Option. Any Incentive Stock Option shall contain such limitations and
restrictions upon the exercise of the Option as shall be necessary in order that
the Option shall be an "incentive stock option" as defined in section 422 of the
Internal Revenue Code.

     (I)   COMPLIANCE WITH SECURITIES LAWS.  At the time of exercise of any
           ------------------------------- 
Option, the Company may require the Optionee to execute any documents or take
any action which may then be necessary to comply with the Securities Act and the
rules and regulations adopted thereunder, or any other applicable federal or
state laws regulating the sale and issuance of securities, and the Company may,
if it deems necessary, include provisions in the Options to assure such
compliance. The Company may from time to time change its requirements with
respect to enforcing compliance with federal and state securities laws,
including the request for, or insistence upon, letters of investment intent,
such requirements to be determined by the Company in its judgment as necessary
to assure compliance with said securities laws. Such changes may be made with
respect to any particular Option or to any stock issued upon exercise thereof.

                                Appendix A - 4
<PAGE>
 
     6.  ADJUSTMENTS UPON CHANGES IN CAPITALIZATION.  In the event of any
         ------------------------------------------
change in the number of issued and outstanding shares of Common Stock which
results from a stock split, reverse stock split, the payment of a stock dividend
or any other change in the capital structure of the Company, such as a merger,
consolidation, reorganization or recapitalization, the Committee shall
appropriately adjust (a) the maximum number of shares which may be issued under
this Plan, (b) the number of shares subject to each outstanding Option, and (c)
the Option Price per share thereof, so that upon exercise of the Option the
Optionee shall receive the same number of shares the Optionee would have
received had the Optionee been the holder of all shares subject to such
outstanding Options immediately before the effective date of such change in the
number of issued shares of the Common Stock of the Company. Any such adjustment
shall not result in or entitle the Optionee to the issuance of fractional
shares. Instead, appropriate adjustments to any such Option and, in the
aggregate, all other options of the Company of the same class (that is,
Incentive Stock Options or Nonqualified Options) held by each Optionee shall be
made so that such Option and other options of the same class, if any, held by
any such Optionee cover the greatest whole number of shares of the Common Stock
which does not exceed the number of shares which would be covered applying such
adjustments in the absence of any restriction on the issuance of fractional
shares. Any excess fractional share shall be redeemed in cash at the then-
current fair market value of the Common Stock (determined as provided in Section
                                                                         -------
5(A) hereof) multiplied by the appropriate fraction of a share.
- ----

     7.  TERMINATION OR AMENDMENT OF THE PLAN.  The Board of Directors may at
         ------------------------------------
any time suspend, amend, or terminate this Plan, provided that, except as set
forth in Section 6 hereof, no amendment may be adopted that will change the
         --------- 
requirement that the Option Price be at least a specified percentage of the fair
market value of the Common Stock or change the provisions required for
compliance with section 422 of the Internal Revenue Code, except to conform to a
change in the requirements of such law or regulations thereof. Except as
otherwise specifically provided herein, the Board shall not, without the
approval of the shareholders of the Company, amend this Plan so as to materially
increase the benefits accruing to Optionees under the Plan, increase the
aggregate number of shares that may be issued under this Plan or materially
modify the requirements for eligibility for participation in the Plan. No
amendment or termination of the Plan shall, without the consent of the Optionee,
alter or impair any rights or obligations under any Option previously granted
under the Plan.

7.  RESERVE ACCOUNT
    ---------------

          A) Provided that Merchant's actual Chargebacks are within the limits
          established by the then effective operating regulations of VISA and/or
          MasterCard, (such limits currently in effect as of the date of this
          agreement are shown in Paragraph 8 below) the Reserve Account
          collection rate will be set by Bank at the rate of twenty percent
          (20%) of each gross monthly deposit, with a holding period of six (6)
          months. In the event that Merchant's actual Chargebacks exceed the
          limits established by VISA and/or MasterCard, Bank retains the right
          to increase the Reserve Account collection rate by a minimum of four
          percent (4%) of each gross monthly deposit for every one percent (1%)
          or part thereof that actual Chargebacks exceed the applicable VISA
          and/or MasterCard limit, up to a maximum of one hundred percent (100%)
          of each gross monthly deposit, and to increase the holding period by a
          minimum of one additional month for each one percent (1%) or part
          thereof that actual Chargebacks exceed the applicable VISA and/or
          MasterCard limit, up to the entire period of time that any such
          Chargebacks remain valid under VISA and/or MasterCard rules and
          regulations then in effect.

          B) Additionally, if Merchant has an extraordinary dollar amount or
          number of transactions which have been or are likely to be charged
          back to Bank pursuant to the then effective operating regulations of
          VISA and/or MasterCard.

                                   SCHEDULE A

          Bank reserves the right to provide Merchant with thirty (30) days
          prior written notice of Bank's intent to terminate this Agreement.

          If, during such thirty (30) day notice period, Merchant is successful
          in reducing its chargeback ratio to a level which complies with the
          then effective operating regulations of VISA and/or MasterCard, then
          Bank agrees to reconsider its intent to terminate this Agreement, and
          to negotiate with Merchant the terms and conditions pursuant to which
          Bank would be willing to continue its contractual relationship with
          Merchant under a modified agreement.

          C) If, due to any action by Merchant, the Bank receives notification
          from VISA or MasterCard indicating the possible imposition of fines or
          fees in accordance with the then applicable operating regulations, the
          Bank reserves the right to withhold an amount it deems appropriate
          until such notification has been rescinded by the notifying
          association.

          D) If the merchant's current monthly deposit exceeds an average of the
          previous four months deposit by 25%, the Bank may, at its sole
          discretion, withhold an amount deemed appropriate until such time as
          the bank is satisfied such increase represents a valid increase in the
          merchant's business. It is incumbent upon the merchant to advise the
          Bank and TBR of such increase prior to submission of records for
          processing.

          E) Upon Notice of Termination of this Agreement by either party,
          Merchant understands that Bank cannot determine with certainty whether
          a sale will be charged back to Bank until the chargeback period
          expires as to that sale. Therefore, Bank shall have the right to
          suspend Merchant's right to withdraw any funds from any deposit
          account maintained by Merchant with Bank, including, without
          limitation, merchant's designated deposit account; provided, however,
          that Bank shall not suspend such right in a fashion which would
          deprive Merchant of the use of its deposit account or accounts beyond
          the extent required to assure Bank's ability to recover from Merchant,
          all chargebacks, fees, fines and other amounts reasonably estimated by
          Bank that will become due to Bank. Bank will notify the Merchant in
          writing within seven (7) days after any termination notice to
          Merchant, the amount, if any, and holding period of funds, not to
          exceed 210 days, to be withheld under the provisions of this
          subparagraph E). Bank further agrees to reinstate Merchant's right to
          withdraw funds from its deposit accounts upon delivery to Bank of a
          bond, letter of credit or another undertaking or collateral security
          reasonably believed by Bank to protect Bank's interests relative to
          such amounts reasonably estimated by Bank that will become due to
          Bank. The specific rights granted Bank in this Section 7.E shall not
          be deemed to limit the generality of the rights granted Bank elsewhere
          in this Agreement with respect to withholding payments, the creation
          of exercise of security interests or otherwise.

          Funds deducted by Bank from each gross monthly deposit for the Reserve
          Account shall be deposited in a non-interest bearing blocked account.
          Funds shall be released by Bank from the Reserve Account to Merchant,
          monthly on a first-in first-out (FIFO) basis at the expiration of the
          applicable holding period.

          aforementioned fees and charges, and expressly authorizes Bank to
          deduct such fees and charges from Merchant's Daily Income, Merchant's
          Demand Deposit Account, and Merchant's Reserve Account.

          Merchant hereby authorizes Bank to hold the Daily Income for five (5)
          business days. After the five-business day holding period, Bank will
          remit the net balance in the Demand Deposit Account to Merchant via an
          ACH transfer to a financial institution designated by the Merchant.

    ----------------------------------------------

          A) Provided that Merchant's actual Chargebacks are within acceptable
          limits for each Travel & Entertainment Card processed, the Reserve
          Account collection rate will be set at the rate of twenty percent
          (20%) of each gross monthly deposit, with a holding period of six (6)
          months. In the event that Merchant's actual Chargebacks exceed the
          limits, the Reserve Account collection rate may be increased by a
          minimum of four percent (4%) of each gross monthly deposit for every
          one percent (1%) or part thereof that actual Chargebacks exceed 5% of
          that month's Gross Monthly Deposit, up to a maximum of one hundred
          percent (100%) of each gross monthly deposit, and the holding period
          may be increased by a minimum of one additional month for each one
          percent (1%) or part thereof that actual Chargebacks exceed 5% of that
          month's gross monthly deposit, up to the entire period of time that
          any such Chargebacks remain valid under rules and regulations then in
          effect.

          B) Additionally, if Merchant has an extraordinary dollar amount or
          number of transactions which have been or are likely to be charged
          back pursuant to the then effective operating regulations of the card
          companies, TBR reserves the right to provide Merchant with thirty (30)
          days prior written notice of it's intent to terminate this Agreement.

                                  SCHEDULE B

          If. during such thirty (30) day notice period, Merchant is successful
          in reducing its chargeback ratio, then TBR agrees to reconsider its
          intent to terminate this Agreement, and to negotiate with Merchant the
          terms and conditions pursuant to which TBR would be willing to
          continue its contractual relationship with Merchant under a modified
          agreement.

          C) If the merchant's current monthly deposit exceeds an average of the
          previous four months deposit by 25%, TBR may, at its sole discretion,
          withhold an amount deemed appropriate until such time as TBR is
          satisfied such increase represents a valid increase in the merchant"s
          business. It is incumbent upon the merchant to advise TBR of such
          increase prior to submission of records for processing.

          D) Upon Notice of Termination of this Agreement by either party,
          Merchant understands that TBR cannot determine with certainty whether
          a sale will be charged back to TBR until the chargeback period expires
          as to that sale. Therefore, TBR shall have the right to suspend
          Merchant's right to future payments provided, however, that TBR shall
          not suspend such right in a fashion which would deprive Merchant of
          the use of its funds beyond the extent required to assure TBR's
          ability to recover from Merchant, all chargebacks, fees, fines and
          other amounts reasonably estimated by TBR that will become due to TBR.
          TBR will notify the Merchant in writing within seven (7) days after
          any termination notice to Merchant, the amount, if any, and holding
          period of funds to be withheld under the provisions of this
          subparagraph D). TBR further agrees to reinstate Merchant's right to
          withdraw funds from its accounts upon delivery to TBR of a bond,
          letter of credit or another undertaking or collateral security
          reasonably believed by TBR to protect TBR's interests relative to such
          amounts reasonably estimated by TBR that will become due to TBR. The
          specific rights granted TBR in this Section 6.D shall not be deemed to
          limit the generality of the rights granted TBR elsewhere in this
          Agreement with respect to withholding payments, the creation of
          exercise of security interests or otherwise.

          Funds deducted by TBR from each gross monthly deposit for the Reserve
          Account shall be deposited in a non-interest bearing blocked account.
          Funds shall be released by TBR from the Reserve Account to Merchant,
          monthly on a first-in flrst-out (FIFO) basis at the expiration of the
          applicable holding period.

          The Board of Directors is authorized to establish, from time to time,

                                  ARTICLE IV.

                                  ARTICLE V.

                             ELECTION OF DIRECTORS

     A.   The business and affairs of the Company shall be conducted and managed
by, or under the direction of, the Company's Board of Directors (the "Board"). 
The total number of directors constituting the entire Board shall be fixed and 
may be altered from time to time by or pursuant to a resolution passed by the 
Board.

     B.   The Board shall be divided into three classes, Class A, Class B, and 
Class C. Such classes shall be as nearly equal in number of directors as 
possible. Each director shall serve for a term expiring at the third annual 
meeting following the annual meeting at which such director was elected; 
provided, however, that the directors first elected to Class A shall serve for 
an initial term expiring at the annual meeting following the end of the 
Company's 1996 fiscal year, the directors first elected to Class B shall serve 
for an initial term expiring at the second annual meeting next following the end
of the Company's 1996 fiscal year, and the directors first elected to Class C 
shall serve for an initial term expiring at the third annual meeting next 
following the end of the Company's 1996 fiscal year. The foregoing 
notwithstanding, except as otherwise provided in this Certificate or any 
resolution or resolutions of the Board designating a series of Preferred Stock, 
directors who are elected at an annual meeting of stockholders, and directors 
elected in the interim to fill vacancies and newly created directorships, shall 
hold office for the

                                       2
<PAGE>
 
term for which elected and until their successors are elected and qualified or 
until their earlier death, resignation or removal. Whenever the holders of any 
class or classes of stock or any series thereof shall be entitled to elect one 
or more directors pursuant to any resolution or resolutions of the Board 
designating a series of Preferred Stock, and except as otherwise provided herein
or therein, vacancies and newly created directorships of such class or classes 
or series thereof may be filled by a majority of the directors elected by such
class or classes or series thereof then in office, by a sole remaining director
so elected or by the unanimous written consent or the affirmative vote of a
majority of the outstanding shares of such class or classes or series entitled
to elect such director or directors.

     C.   Except as otherwise provided for herein, newly created directorships 
resulting from any increase in the authorized number of directors, and any 
vacancies on the Board resulting from death, resignation, disqualification, 
removal or other cause, may be filled only by the affirmative vote of a majority
of the remaining directors then in office, even though less than a quorum of the
Board. Any director elected in accordance with the preceding sentence shall hold
office for the remainder of the full term of the newly created directorship or 
for the directorship in which the vacancy occurred, and until such director's 
successor shall have been duly elected and qualified, subject to his earlier 
death, disqualification, resignation or removal. Subject to the provisions of 
this Certificate, no decrease in the number of directors constituting the Board 
shall shorten the term of any incumbent director.

     D.   Except as otherwise provided in any resolution or resolutions of the
Board designating a series of Preferred Stock, any director may be removed from
office only by the affirmative vote of the holders of 66 2/3% or more of the
combined voting power of the then-outstanding shares of capital stock of the
Company entitled to vote at a meeting of stockholders called for that purpose,
voting together as a single class.

                                  ARTICLE VI.

                           MEETINGS OF STOCKHOLDERS

     A.   Meetings of stockholders of the Company ("Stockholder Meetings") may 
be held within or without the State of Delaware, as the Bylaws may provide. 
Except as otherwise provided in any resolution or resolutions of the Board 
designating a series of Preferred Stock, special Stockholder Meetings may be 
called only by (i) the President of the Company or (ii) the Board pursuant to a 
resolution adopted by a majority of the then-authorized number of directors of 
the Company. Special Stockholder Meetings may not be called by any other person 
or persons or in any other manner. Elections of directors need not be by written
ballot unless the Bylaws of the Company (the "Bylaws") shall so provide.

     B.   In addition to the powers conferred on the Board by this Certificate 
and by the Delaware General Corporation Law, and without limiting the generality
thereof, the Board is specifically authorized from time to time, by resolution 
of the Board without additional authorization by the stockholders of the 
Company, to adopt, amend or repeal the Bylaws, in such form and with such terms 
as the Board may determine, including, without limiting the generality of the 
foregoing, Bylaws relating to (i) regulation of the procedure for submission by 
stockholders

                                       3
<PAGE>
 
of nominations of persons to be elected to the Board, (ii) regulation of the 
attendance at annual or special Stockholder Meetings by persons other than 
holders of record or their proxies, and (iii) regulation of the business that 
may properly be brought by a stockholder of the Company before an annual or 
special meeting of stockholders of the Company.

                                 ARTICLE VII.

                              STOCKHOLDER CONSENT

     Except as otherwise provided in any resolution or resolutions of the Board 
designating a series of Preferred Stock, no action that is required or permitted
to be taken by the stockholders of the Company at any annual or special meeting 
of stockholders may be effected by written consent of stockholders in lieu of a 
meeting of stockholders, unless the action to be effected by written consent of 
stockholders and the taking of such action by such written consent have 
expressly been approved in advance by the Board.

                                 ARTICLE VIII.

                            LIMITATION OF LIABILITY

     A director of the Company shall not be personally liable to the Company or 
its stockholders for monetary damages for breach of fiduciary duty as a 
director; provided, however, that this Article shall not eliminate or limit the 
liability of a director: (i) for any breach of the director's duty of loyalty to
the Company or stockholders, (ii) for acts or omissions not in good faith or 
which involve intentional misconduct or a knowing violation of law, (iii) under 
section 174 of the Delaware General Corporation Law, or (iv) for any transaction
from which the director derived an improper personal benefit.

     If the Delaware General Corporation Law is amended after the date of filing
of this Certificate to authorize corporate action further limiting or 
eliminating the personal liability of a director, then the liability of the 
directors of the Company shall be limited or eliminated to the fullest extent 
permitted by the Delaware General Corporation Law, as so amended. Any repeal or 
modification of this Article by the stockholders of the Company or otherwise 
shall not adversely affect any right or protection of a director of the Company 
existing at the time of such repeal or modification.

                                  ARTICLE IX.

                                  SECTION 203

     The Company shall be governed by Section 203 of the Delaware General 
Corporation Law.

                                  ARTICLE X.

                                INDEMNIFICATION

     The Company shall indemnify each director and officer of the Company who 
may be indemnified, to the fullest extent permitted by Section 145 of the 
Delaware General Corporation Law ("Section 145"), as it may be amended from time
to time, in each and every situation where the Company is obligated to make such
indemnification pursuant to Section 145. In addition, the Company shall 
indemnify each of the Company's directors and officers in each and every 
situation where, under Section 145, the Company is not obligated, but is 
permitted or empowered, to make such indemnification. The Company may, in the 
sole discretion of the Board, indemnify any other person who may be indemnified 
pursuant to Section 145 to the extent the Board deems advisable, as permitted by
such section. The Company shall promptly make or cause to be made any 
determination which Section 145 requires.

                                  ARTICLE XI.

                       AMENDMENT OF CORPORATE DOCUMENTS

     A.   Certificate. Whenever any vote of the holders of voting shares of 
          -----------
capital stock of the Company is required by law to amend, repeal or rescind any 
provision of this Certificate, then in addition to any affirmative vote required
by applicable law and in addition to any vote of the holders of any series of 
Preferred Stock, as provided in any resolution or resolutions of the Board 
designating a series of Preferred Stock, such alteration, amendment, repeal or 
rescission (a "Change") of any provision of this Certificate must be approved by
at least a majority of the then-authorized number of directors and by the
affirmative vote of the holders of at least a majority of the combined voting
power of the then-outstanding voting shares of capital stock of the Company,
voting together as a single class; provided, however, that if any such Change
relates to Articles III, V, VI, VII, VIII, IX, X or to this Article XI, such
Change must also be approved by the affirmative vote of the holders of at least
662/3% of the combined voting power of the then-outstanding voting shares of
capital stock of the Company, voting together as a single class; provided
further, however, that the vote(s) required by the immediately preceding clause
shall not be required if such Change has been first approved by at least two-
thirds of the then-authorized number of directors.

          Subject to the provisions hereof, the Company reserves the right at 
any time, and from time to time, to amend, alter, repeal or rescind any 
provision contained in this Certificate in the manner now or hereafter 
prescribed by law, and other provisions authorized by the laws of the State of 
Delaware at the time in force may be added or inserted, in the manner now or 
hereafter prescribed by law; and all rights, preferences and privileges of 
whatsoever nature conferred upon stockholders, directors or any other persons 
whomsoever by and pursuant to this Certificate in its present form or as 
hereafter amended are granted subject to the rights reserved in this article.

     B.   Bylaws. In addition to any affirmative vote required by law, any 
          ------ 
Change of the Bylaws may be adopted either (i) by the Board by the affirmative 
vote of at least a majority of

                                       5
<PAGE>
 
the then-authorized number of directors, or (ii) by the stockholders by the 
affirmative vote of the holders of at least 662/3% of the combined voting power
of the then-outstanding voting shares of capital stock of the Company, voting 
together as a single class.

                                  ARTICLE XII.

directors or officers, or between the Company and any other corporation, 
partnership, association, or other organization in which one or more of its 
directors or officers, are directors or officers, or have a financial interest, 
shall be void or voidable solely for this reason, or solely because the director
or officer is present at or participates in the meeting of the Board or 
committee which authorizes the contract or transaction, or solely because his or
their votes are counted for such purpose, if:

     the contract or transaction are disclosed or are known to the stockholders 
     entitled to vote thereon, and the contract or transaction is specifically 
     approved in good faith by a vote of the stockholders; or

          (3)  The contract or transaction is fair as to the Company as of the 
     time it is authorized, approved or ratified, by the Board, a committee or
     the stockholders.

     B.   Common or interested directors may be counted in determining the 
presence of a quorum at a meeting of the Board or of a committee which 
authorizes the contract or transaction.

                                       2
<PAGE>
 
or at the direction of the Board, (ii) otherwise properly brought before the
meeting by or at the direction of the Board or (iii) brought before the meeting
by a stockholder of record entitled to vote at such meeting if written notice of
such stockholder's intent to bring such business before such meeting is
delivered to, or mailed, postage prepaid, and received by, the Secretary at the
principal executive offices of the Company not later than the close of business
on the tenth day following the date on which the Company first makes public
disclosure of the date of the annual meeting; provided, however, that if the
annual meeting is adjourned, and the Company is required by Delaware law to give
notice to stockholders of the adjourned meeting date, written notice of such
stockholder's intent to bring such business before the meeting must be delivered
to or received by the Secretary no later than the close of business on the fifth
day following the earlier of (1) the date the Company makes public, disclosure
of the date of the adjourned meeting or (2) the date on which notice of such
adjourned meeting is first given to stockholders. Each notice given by such
stockholder shall set forth: (A) a brief description of the business desired to
be brought before the meeting and the reasons for conducting such business at
the meeting; (B) the name and address of the stockholder who intends to propose
such business; (C) a representation that the stockholder is a holder of record

a representation that the stockholder is a holder of record at the time of such
notice and intends to be a holder of record on the record date for such meeting)
and intends to appear in person or by proxy at such meeting to propose such
business; and (D) any material interest of the stockholder, if any, in such
business. The chairman of the meeting may refuse to transact any business at any
meeting made without compliance with the foregoing procedure. For this Section
2.6, public disclosure shall be deemed to first be given to stockholders when
disclosure of such date of the meeting of stockholders is first made in a press
release reported by the Dow Jones News Services, Associated Press or comparable
national news service, or in a document publicly filed by the Company with the
Securities and Exchange Commission pursuant to Sections 13, 14 or 15(d) of the
Securities Exchange Act of 1934, as amended. 


     Section 2.7.  Voting of Shares.
                   ----------------

          Section 2.7.1  Voting Lists.  The officer or agent who has charge of
                         ------------
the stock ledger of the Company shall prepare, at least 10 days before every
meeting of stockholders, a complete list of the stockholders entitled to vote
thereat arranged in alphabetical order and showing the address and the number of
shares registered in the name of each stockholder. Such list shall be open to
the examination of any stockholder, for any purpose germane to the meeting,
during ordinary business hours for a period of at least 10 days prior to the
meeting, either at a place within the city where the meeting is to be held,
which place shall be specified in the notice of the meeting, or, if not so
specified, at the place where the meeting is to be held. The list shall also be
produced and kept at the time and place of the meeting during the whole time
thereof, and may be inspected by any stockholder who is present. The original
stock transfer books shall be prima facie evidence as to who are the
stockholders entitled to examine such list or transfer books or to vote at any
meeting of stockholders. Failure to comply with the requirements of this Section
shall not affect the validity of any action taken at said meeting.

          Section 2.7.2  Votes Per Share.  Each outstanding share of capital
                         ---------------
stock shall be entitled to vote in accordance with the provisions for voting
included in the Certificate. In determining the number of shares of stock
required by law, by the Certificate or by the Bylaws 

                                       3
<PAGE>
 
to be represented for any purpose, or to determine the outcome of any matter
submitted to stockholders for approval or consent, the number of shares
represented or voted shall be weighted in accordance with the provisions of the
Certificate regarding voting powers of each class of stock. Any reference in
these Bylaws to a majority or a particular percentage of the voting stock or a
majority or a particular percentage of the capital stock shall be deemed to
refer to a majority or a particular percentage, respectively, of the voting
power of such stock. Issues shall be determined by a class vote only when a
class vote is required by law or the Certificate.

          Section 2.7.3.  Proxies.  Every Stockholder entitled to vote at a
                          -------    
meeting or to express consent or dissent without a meeting or a stockholder's
duly authorized attorney-in-fact may authorize another person or persons to act
for him by proxy. Each proxy shall be in writing, executed by the stockholder
giving the proxy or by his duly authorized attorney. No proxy shall be voted on
or after three years from its date, unless the proxy provides for a longer
period. Unless and until voted, every proxy shall be revocable at the pleasure
of the person who executed it, or his legal representatives or assigns, except
in those cases where an irrevocable proxy permitted by statute has been given.

          Section 2.7.4.  Required Vote.  When a quorum is present at any
                          -------------
meeting, the vote of the holders, present in person or represented by proxy, of
capital stock of the Company representing a majority of the votes of all capital
stock of the Company entitled to vote thereat shall decide any question brought
before such meeting, unless the question is one upon which, by express provision
of law or the Certificate or these Bylaws, a different vote is required, in
which case such express provision shall govern and control the decision of such
question.

          Section 2.7.5.  Consents in Lieu of Meeting.  Pursuant to Article VII
                          ---------------------------
of the Company's Certificate, no action that is required or permitted to be
taken by the stockholders of the Company at any annual or special meeting of
stockholders may be effected by written consent of stockholders in lieu of a
meeting of stockholders, unless, subject to certain exceptions contained in the
Certificate, the action to be effected by written consent of stockholders and
the taking of such action by such written consent have expressly been approved
in advance by the Board.


     Section 2.8.  Inspectors of Election.  The Company shall, in advance of any
                   ----------------------
meeting of stockholders, appoint one or more inspectors of election, who may be
employees of the Company, to act at the meeting or any adjournment thereof and
to make a written report thereof. The Company may designate one or more persons
as alternate inspectors to replace any inspector who fails to act. If no
inspector so appointed or designated is able to act at a meeting of
stockholders, the chairman or the person presiding at the meeting shall appoint
one or more inspectors to act at the meeting. Each inspector, before entering
upon the discharge of his or her duties, shall take and sign an oath to execute
faithfully the duties of inspector with strict impartiality and according to the
best of his or her ability.

     The inspector or inspectors so appointed or designated shall: (a) ascertain
the number of shares of capital stock of the Company outstanding and the voting
power of each such share; (b) determine the shares of capital stock of the

capacity with another corporation, partnership, joint venture or trust or other

incurred by him in connection with the defense or settlement of such action or
suit if he acted in good faith and in a manner he reasonably believed to be in
or not opposed to the best interests of the Company and except that no
indemnification shall be made in respect to any claim, issue or matter as to
which such person shall have been adjudged to be liable to the Company unless
and only to the extent that the Court of Chancery or the court in which such
action or suit was brought shall determine upon application that, despite the

person is fairly and reasonably entitled to indemnity for such expenses which
the Court of Chancery or such other court shall deem proper.

director of the Company) or may (in the case of any pending threatened action,
suit or proceeding against an officer) be paid by the Company in advance of the
final disposition of such action, suit or proceeding upon receipt of an
undertaking by or on behalf of such director or officer to repay such amount if
it shall ultimately be determined that he is not entitled to be indemnified by
the Company as authorized by law or in this Article VIII.

     Section 8.5.  Nonexclusive.  The indemnification and advancement of
                   ------------
expenses provided by, or granted pursuant to, this Article VIII shall not be
deemed exclusive of any other rights to which any director, officer, employee or
agent of the Company seeking indemnification or advancement of expenses may be
entitled under any other provision of there Bylaws or by the Certificate, an
agreement, a vote of stockholders or disinterested directors or otherwise, both
as to action in his official capacity and as to action in another capacity while
holding such office, and shall, unless otherwise provided when authorized or
ratified, continue as to a person who has ceased to be a director, officer,
employee or agent of the Company and shall inure to the benefit of the heirs,
executors and administrators of such a person.

     Section 8.6  Indemnification of Employees and Agents of the Company.  The

liability under provisions of applicable law, the Certificate or this Article

     1.   The Customer agrees to install and maintain the Equipment as part of
the "turn-key" telecommunications services (the "Services"), specified in
Addendum 1, to be provided to Customer, whose address and service locations are
listed on Addendum 1. Upon execution by Customer and acceptance by Company, this
document becomes a binding contract between them. The term "Customer" shall
include all subsidiaries of Customer.

     2.   TERM. This Agreement shall terminate sixty (60) months from the date
Customer accepts the Services per paragraph 4, except as provided otherwise
herein.

     3.   CUSTOMER'S COMMITMENT. Customer hereby agrees to pay the amounts
specified in Addendum 2 for the Services for the term of this Agreement and to
perform the obligations specified in Paragraph 11 below.

     4.   INSTALLATION SERVICES. The Company will install the Equipment at the
Customer sites designated in Addendum 1, will perform site surveys and will make
all necessary filings required in connection with the installation of the
Equipment and operation of the Services, including those with the Mexican
government. Prior to the installation by the Company, Customer shall have
completed its obligations specified in Paragraph 11 below, and shall have
notified the Company in writing of such completion. Upon completion of
installation, Company and Customer shall conduct all such tests as either
reasonably deems necessary to confirm operation of the Equipment and Services.
Acceptance by Customer shall mark the beginning of the term established by
paragraph 2, and billing of the Base Monthly Service Charges shall commence as
of that date.

     5.   SERVICE PERFORMANCE. The Services shall have a digital bit error rate
of 10/7/ or better, per circuit ("Service Performance Standards"). The Company
states, and Customer acknowledges, that satellite signal transmission services
within the United States of Mexico are, by Mexican law, provided exclusively by
a dependency of the Mexican government. Notwithstanding this, however, the
Company shall be responsible for managing the satellite spectrum allocated to
Customer and for ensuring that such signal transmission services (as well as
other Services provided hereunder) are provided in accordance with the Service
Performance Standards. A "Service Interruption" shall occur for the period of
time that the Services fail to meet the Service Performance Standards. A Service
Interruption begins when the Company independently becomes aware of a Service
Interruption or when the Company acknowledges Customer's notification of

                                    Page 2

- --------------------------------------------------------------------------------

Service Interruption and ends at the time that the Services have been restored
to applicable Service Performance Standards. Company shall immediately
acknowledge notification of a Service Interruption upon receipt of notice from
Customer. If a Service Interruption occurs of greater than four (4) continuous
hours during the normal business hours, Customer shall be credited against its
Base Monthly Service Charge for the month next following for each hour the
Service Interruption continues based on a 720-hour month. A failure to meet the
applicable Service Performance Standards will not constitute a Service
                                              ---
Interruption when that failure is the result of any of the following causes:

     (a)  The failure or non-performance of any Customer-provided facilities or
equipment;

     (b)  An act or failure to act of Customer, its employees, or agents;

     (c)  Customer-requested Service or Equipment modification;

     (d)  Suspensions or terminations of Service made in accordance with these
standard terms and conditions;

     6.   MAINTENANCE; OUTAGE RESPONSE PROCEDURE.  The Company shall provide all
necessary and required maintenance, including regular, scheduled maintenance for
the Equipment pursuant to this Agreement and in consideration for the Base
Monthly Service Charge specified in Addendum 2.  When the Company receives
notification or independently becomes aware of a service problem, Company shall
immediately begin diagnostic efforts to isolate the source of the service
outage.  If dispatch of service personnel is required, such personnel shall be
dispatched within a reasonable period of time and in accordance with commercial
transportation schedules.  The Company shall use all commercially reasonable
efforts to remedy the service problems as soon as possible.  Unless approved in
writing by Company, no party other than Company or its designee shall provide
any maintenance, installation or repair services in connection with the
Equipment or Services.

     7.   RENEWAL.  This Agreement will be renewed automatically at the end of
the initial sixty (60) months for additional terms of twelve (12) months
unless, not less than ninety (90) days before the expiration of the then-
effective term, either party notifies the other in writing of its intention not
to renew.

     8.   CHARGES AND PAYMENT.

     The Base Monthly Service Charge specified in Addendum 2 is payable in
advance each month during the Term of this Agreement.  The Base Monthly Service
Charge for less than a full month will be prorated on a thirty (30) day month
basis.  Company shall invoice Customer at the beginning of each month for
charges due for such month and Customer

shall pay the Company all charges due within ten (10) days of billing date.
Customer shall have the option of payment via wire transfer as specified in
Addendum 2. In the event that any charges are not paid by the Customer when due,
the Company reserves the right, consistent with Paragraphs 15 and 16 below, to
terminate this Agreement for cause, or, in the alternative, to charge Customer a
late payment charge calculated on the outstanding balance then due, with such
late payment charge equal to the maximum late-payment charge allowable under
Texas law, up to 1.5 percent per month on the unpaid balance.

    9.    ASSIGNMENT. Neither party shall assign this Agreement without the
prior written consent of the other party, which consent will not be withheld or
delayed unreasonably. Any party to whom the rights and obligations under this
Agreement are assigned shall assume all such assigned rights and obligations in
full, and all performance standards and customer remedies for performance
failures shall remain in force.

Company.
