(1) This registration statement relates to shares of common stock, par value
    $.01 per share, of World Access, Inc. ("World Access Common Stock") issuable
    to holders of capital stock of Telco Systems, Inc., a Delaware corporation
    ("Telco Systems"), in the proposed merger of Telco Systems with and into a
    wholly owned subsidiary of World Access, Inc. (the "Merger").
(2) The number of shares to be registered is based upon an estimate of the
    maximum number of shares of common stock, par value $.01 per share, of Telco
    Systems ("Telco Systems Common Stock") presently outstanding and reserved
    for issuance under various plans or instruments or otherwise expected to be
    issued on or before the closing date of the Merger multiplied by the
    approximate exchange ratio of .5862 shares of World Access Common Stock for
    each share of Telco Systems Common Stock.
(3) Calculated in accordance with Rule 457(f)(1) under the Securities Act, based
    on the aggregate market value on November 6, 1998 of the shares of Telco
    Systems Common Stock expected to be exchanged in connection with the Merger
    and computed by dividing (i) the product of (A) the average of the high and
    low prices of Telco Systems Common Stock as reported on The Nasdaq National
    Market on November 6, 1998 ($13.375) and (B) 13,787,584, representing the
    maximum number of shares of Telco Systems Common Stock presently outstanding
    and reserved for issuance under various plans or instruments or otherwise
    expected to be exchanged in connection with the Merger, by (ii) 8,082,282,
    representing the maximum number of shares of World Access Common Stock
    expected to be issued in connection with the Merger.
(4) The registration fee of $51,266 was calculated pursuant to Rule 457(f) under
    the Securities Act as follows: $278 per $1,000,000 (or fraction thereof) of
    the proposed maximum aggregate offering price. A fee of $31,980 was paid on
    July 31, 1998 pursuant to Section 14(g) of the Securities Exchange Act of
    1934, as amended, in connection with the filing of preliminary proxy
    materials by World Access, Inc. and Telco Systems. Pursuant to Rule 457(b)
    under the Securities Act, the registration fee payable herewith has been
    reduced by $31,980, the amount previously paid upon filing of such
    preliminary proxy materials. Accordingly, an additional fee of $19,286 is
    required to be and has been paid with the initial filing of this
    Registration Statement.
                             ---------------------

DATES AS MAY BE NECESSARY TO DELAY ITS EFFECTIVE DATE UNTIL THE REGISTRANT SHALL
FILE A FURTHER AMENDMENT WHICH SPECIFICALLY STATES THAT THIS REGISTRATION
STATEMENT SHALL THEREAFTER BECOME EFFECTIVE IN ACCORDANCE WITH SECTION 8(A) OF

     The purposes of the World Access Special Meeting are as follows:
 
          1. To approve and adopt the Agreement and Plan of Merger and
     Reorganization, dated as of June 4, 1998, as amended (as so amended, the
     "Merger Agreement"), among World Access (formerly known as WAXS INC.), WA
     Telcom Products Co., Inc. (formerly known as World Access, Inc.), a
     Delaware corporation and a direct wholly owned subsidiary of World Access
     ("Old World Access"), Telco Systems, Inc., a Delaware corporation ("Telco
     Systems"), and Tail Acquisition Corporation, a Delaware corporation and a
     direct wholly owned subsidiary of World Access ("Merger Sub"), which
     provides, among other things, for the merger of Telco Systems with and into
     Merger Sub (the "Merger"), with Merger Sub (then to be known as "Telco
     Systems, Inc.") continuing as the surviving corporation and a direct wholly
     owned subsidiary of World Access, and for the issuance (the "Share
     Issuance") of shares of World Access common stock, par value $.01 per share
     (the "World Access Common Stock"), and, at the election of World Access,
     the payment of cash (subject to certain limitations) in exchange for shares
     of Telco Systems common stock in the Merger. At the effective time of the
     Merger (the "Effective Time"), each outstanding share of common stock, par
     value $.01 per share, of Telco Systems (the "Telco Systems Common Stock")
     (together with the right to purchase one-hundredth of a share of Series A
     Participating Cumulative Preferred Stock, par value $.01 per share, of
     Telco Systems) (other than (i) shares owned by Telco Systems, World Access
     or Old World Access, which will be cancelled, and (ii) shares held by

     be converted into and become exchangeable for that number of shares of
     World Access Common Stock (the "Exchange Ratio") equal to the quotient of
     $17.00 divided by the average of the last reported sales prices of one
     share of World Access Common Stock on The Nasdaq National Market during the
     period of the 20 most recent trading days ending three business days before
     the Effective Time (the "World Access Market Price") (unless the World
     Access Market Price exceeds $36.00 per share, in which case each
     outstanding share of Telco Systems Common Stock will be converted into
     .4722 shares of World Access Common Stock, or unless the World Access
     Market Price is less than $29.00 per share, in which case each outstanding
     share of Telco Systems Common Stock will be converted into .5862 shares of
     World Access Common Stock), provided that (i) the nominal value of the
     consideration to be received by holders of Telco Systems Common Stock will
     be no less than $12.00 per share (the "Minimum Nominal Value") and (ii)
     World Access may elect to pay cash in lieu of issuing shares of World
     Access Common Stock so long as such cash does not comprise more than 55% of
     the total consideration to be received by Telco Systems stockholders (based
     on the average of the high and low trading prices of World Access Common
     Stock on the day the Merger is consummated). Also at the Effective Time,
     each outstanding option to purchase Telco Systems Common Stock will be
     assumed by World Access and converted into an option to purchase shares of
     World Access Common Stock as adjusted to account for the Exchange Ratio and
     the Minimum Nominal Value;
 
          2. To approve an amendment to the World Access Certificate of
     Incorporation to increase the number of authorized shares of World Access
     Common Stock to 150,000,000;
<PAGE>   4
 
          3. To adopt the World Access, Inc. 1998 Incentive Equity Plan;

     and certain officers of World Access; and
 
          5. To transact such other business as may properly come before the
     World Access Special Meeting or any adjournments or postponements thereof.
 
     The Merger and the Merger Agreement, as well as the other proposals
identified above to be considered at the World Access Special Meeting, are more
fully described in the accompanying Joint Proxy Statement/Prospectus.

                   NOTICE OF SPECIAL MEETING OF STOCKHOLDERS
                        TO BE HELD ON NOVEMBER 30, 1998
 
                             ---------------------
 
To the Stockholders of Telco Systems, Inc.:
 
     NOTICE IS HEREBY GIVEN that a special meeting of stockholders (the "Telco
Systems Special Meeting") of Telco Systems, Inc., a Delaware corporation ("Telco
Systems"), will be held at the principal offices of Telco Systems located at 63
Nahatan Street, Norwood, Massachusetts 02062, on November 30, 1998, at 10:00
a.m., local time, for the following purposes:
 
          1. To consider and vote upon a proposal to approve and adopt the
     Agreement and Plan of Merger and Reorganization, dated as of June 4, 1998,
     as amended (as so amended, the "Merger Agreement"), among World Access,
     Inc. (formerly known as WAXS INC.), a Delaware corporation ("World
     Access"), WA Telcom Products Co., Inc. (formerly known as World Access,
     Inc.), a Delaware corporation and a direct wholly owned subsidiary of World
     Access ("Old World Access"), Telco Systems and Tail Acquisition
     Corporation, a Delaware corporation and a direct wholly owned subsidiary of
     World Access ("Merger Sub"), which provides, among other things, for the
     merger of Telco Systems with and into Merger Sub (the "Merger") with Merger
     Sub (then to be known as "Telco Systems, Inc.") continuing as the surviving
     corporation and a direct wholly owned subsidiary of World Access, and for
     the issuance of shares of World Access common stock, par value $.01 per
     share ("World Access Common Stock"), and, at the election of World Access,
     the payment of cash (subject to certain limitations) in exchange for shares
     of Telco Systems common stock in the Merger. At the effective time of the
     Merger (the "Effective Time"), each outstanding share of common stock, par
     value $.01 per share, of Telco Systems ("Telco Systems Common Stock")
     (together with the right to purchase one-hundredth of a share of Series A
     Participating Cumulative Preferred Stock, par value $.01 per share, of
     Telco Systems) (other than (i) shares owned by Telco Systems, World Access
     or Old World Access, which will be cancelled, and (ii) shares held by
     persons who have perfected their appraisal rights (if applicable) under
     Section 262 of the General Corporation Law of the State of Delaware) will
     be converted into and become exchangeable for that number of shares of
     World Access Common Stock (the "Exchange Ratio") equal to the quotient of
     $17.00 divided by the average of the last reported sales prices of one
     share of World Access Common Stock on The Nasdaq National Market during the
     period of the 20 most recent trading days ending three business days before
     the Effective Time (the "World Access Market Price") (unless the World
     Access Market Price exceeds $36.00 per share, in which case each
     outstanding share of Telco Systems Common Stock will be converted into
     .4722 shares of World Access Common Stock, or unless the World Access
     Market Price is less than $29.00 per share, in which case each outstanding
     share of Telco Systems Common Stock will be converted into .5862 shares of
     World Access Common Stock), provided that (i) the nominal value of the
     consideration to be received by holders of Telco Systems Common Stock will
     be no less than $12.00 per share (the "Minimum Nominal Value") and (ii)
     World Access may elect to pay cash in lieu of issuing shares of World
     Access Common Stock so long as such cash does not comprise more than 55% of
     the total consideration to be received by Telco Systems stockholders (based
     on the average of the high and low trading prices of the World Access
     Common Stock on the day the Merger is consummated). Also at the Effective
     Time, each outstanding option to purchase Telco Systems Common Stock will
     be assumed by World Access and converted into an option to purchase shares
     of World Access Common Stock as adjusted to account for the Exchange Ratio
     and the Minimum Nominal Value; and
 
          2. To transact such other business as may properly come before the
     Telco Systems Special Meeting or any adjournments or postponements thereof.

                               WORLD ACCESS, INC.
                                   PROSPECTUS
                             ---------------------
    This Joint Proxy Statement/Prospectus is being furnished to stockholders of
World Access, Inc., a Delaware corporation ("World Access"), in connection with
the solicitation of proxies by the board of directors of World Access for use at
the special meeting of stockholders (the "World Access Special Meeting") of
World Access to be held at the principal offices of World Access located at 945
E. Paces Ferry Road, Suite 2240, Atlanta, Georgia 30326, on November 30, 1998,
at 10:00 a.m., local time, and at any adjournments or postponements thereof, for
the purposes set forth herein and in the accompanying notice of special meeting
of stockholders of World Access.
 
    This Joint Proxy Statement/Prospectus is also being furnished to
stockholders of Telco Systems, Inc., a Delaware corporation ("Telco Systems"),
in connection with the solicitation of proxies by the board of directors of
Telco Systems for use at the special meeting of stockholders of Telco Systems
(the "Telco Systems Special Meeting") to be held at the principal offices of
Telco Systems located at 63 Nahatan Street, Norwood, Massachusetts 02062, on
November 30, 1998 at 10:00 a.m., local time, and at any adjournments or
postponements thereof, for the purposes set forth herein and in the accompanying
notice of special meeting of stockholders of Telco Systems.
 
    This Joint Proxy Statement/Prospectus also constitutes a prospectus of World
Access with respect to shares of common stock, par value $.01 per share, of
World Access (the "World Access Common Stock") to be issued in connection with
the merger (the "Merger") of Telco Systems with and into Tail Acquisition
Corporation, a Delaware corporation and a direct wholly owned subsidiary of
World Access ("Merger Sub"), with Merger Sub (then to be known as "Telco
Systems, Inc.") continuing as the surviving corporation and a direct wholly
owned subsidiary of World Access, pursuant to the Agreement and Plan of Merger
and Reorganization, dated as of June 4, 1998, as amended (as so amended, the
"Merger Agreement"), among Telco Systems, World Access (formerly known as WAXS
INC.), Merger Sub and WA Telcom Products Co., Inc. (formerly known as World
Access, Inc., "Old World Access"). At the effective time of the Merger (the
"Effective Time"), each outstanding share of common stock, par value $.01 per
share, of Telco Systems (the "Telco Systems Common Stock") (together with the
associated right to purchase one-hundredth of a share of Series A Participating
Cumulative Preferred Stock, par value $.01 per share, of Telco Systems (the
"Associated Rights")) (other than (i) shares owned by Telco Systems, World
Access or Old World Access, which will be cancelled, and (ii) shares held by
persons who have perfected their appraisal rights (if applicable) under Section
262 of the General Corporation Law of the State of Delaware (the "DGCL")) will
be converted into and become exchangeable for that number of shares of World
Access Common Stock equal to (the "Exchange Ratio") the quotient of $17.00
divided by the average of the last reported sale prices of one share of World
Access Common Stock on The Nasdaq National Market ("Nasdaq") during the period
of the 20 most recent trading days ending three business days before the
Effective Time (the "World Access Market Price") (unless the World Access Market
Price exceeds $36.00 per share, in which case each outstanding share of Telco
Systems Common Stock will be converted into .4722 shares of World Access Common
Stock, or unless the World Access Market Price is less than $29.00 per share, in
which case each outstanding share of Telco Systems Common Stock will be
converted into .5862 shares of World Access Common Stock), provided that (i) the
nominal value of the consideration to be received by holders of Telco Systems
Common Stock will be no less than $12.00 per share (the "Minimum Nominal Value")
and (ii) World Access may elect to pay cash in lieu of issuing shares of World
Access Common Stock so long as such cash does not comprise more than 55% of the
total consideration to be received by Telco Systems stockholders (based on the
average of the high and low trading prices of the World Access Common Stock on
the day the Merger is consummated). If World Access elects to pay cash in the
Merger in lieu of issuing shares of World Access Common Stock, then each share
of Telco Systems Common Stock will be exchanged for a pro rata portion of (i)
the aggregate amount of cash that World Access elects to pay (subject to the 55%
limitation described above) (the "Aggregate Cash Pool") and (ii) the aggregate
number of shares of World Access Common Stock to be issued in the Merger, which
will be equal to the number of shares of World Access Common Stock that would
have been issued in the Merger had World Access not elected to include cash in
the merger consideration less that number of such shares having a value (based
upon the World Access Market Price) equal to the Aggregate Cash Pool. The
consideration to be received by the Telco Systems stockholders under the Merger
Agreement is referred to herein as the "Merger Consideration". World Access will
determine and publicly announce what portion (if any) of the Merger
Consideration it will pay in cash on the third business day prior to the
Effective Time. Also at the Effective Time, each outstanding option to purchase
Telco Systems Common Stock will be assumed by World Access and converted into an
option to purchase shares of World Access Common Stock as adjusted to account
for the Exchange Ratio and the Minimum Nominal Value.

    The date of this Joint Proxy Statement/Prospectus is November 10, 1998.
<PAGE>   12
 
(Continued from previous page)
 
     The proposed Merger is contingent upon, among other things, the approval of
the holders of the requisite number of shares of World Access Common Stock and
Telco Systems Common Stock, all as described in this Joint Proxy
Statement/Prospectus. The Merger will be consummated as soon as practicable
after such approvals are obtained and the other conditions to the Merger are
satisfied or waived.
 
     On October 28, 1998, World Access consummated its previously announced
holding company reorganization pursuant to that certain Agreement and Plan of
Merger and Reorganization dated as of February 24, 1998, as amended, by and
between World Access (formerly known as WAXS Inc.), Old World Access (formerly
known as World Access, Inc.), NACT Telecommunications, Inc., a Delaware
corporation ("NACT"), and certain other parties (the "Holding Company
Reorganization"). In accordance with Delaware law, no action or vote by the Old
World Access stockholders was necessary to consummate the Holding Company
Reorganization. As a consequence of the Holding Company Reorganization, the Old
World Access stockholders became stockholders of World Access and Old World
Access, which was renamed "WA Telcom Products Co., Inc.", became a direct wholly
owned subsidiary of World Access. As such, World Access is the successor to Old
World Access and NACT. All references herein to World Access shall mean World
Access, Inc. and its consolidated subsidiaries, unless the context otherwise
requires.
 
     Upon consummation of the Merger (assuming that none of the Merger
Consideration will be paid in cash), the stockholders of World Access as of the
World Access Record Date (as defined elsewhere herein) will own approximately
78.6% of the then-outstanding shares of World Access Common Stock and the
stockholders of Telco Systems as of the Telco Systems Record Date (as defined
elsewhere herein) will own approximately 21.4% (or 10.9% if 55% of the Merger
Consideration is paid in cash) of the then-outstanding shares of World Access
Common Stock. Upon consummation of the Resurgens Transaction (as defined
elsewhere herein), stockholders of World Access as of the World Access Record
Date will own approximately 58.5%, the stockholders of Telco Systems as of the
Telco Systems Record Date will own approximately 15.9% (or 7.9% if 55% of the
Merger Consideration is paid in cash) and the recipients of World Access Common
Stock in the Resurgens Transaction will own approximately 25.6% of the
then-outstanding shares of World Access Common Stock.
 
     On November 9, 1998, the last reported sale prices on Nasdaq of the World
Access Common Stock and the Telco Systems Common Stock were $23 7/8 and $13 3/8,
respectively, and on June 3, 1998, the last full trading day prior to the public
announcement of the execution of the Merger Agreement, the last reported sale
prices on Nasdaq of the World Access Common Stock and the Telco Systems Common
Stock were $29 3/4 and $9 9/16, respectively. On October 12, 1998, the last full
trading day prior to the public announcement of the companies' agreement in
principle to amend the Merger Agreement to provide for, among other things, the
Minimum Nominal Value to be received by the holders of Telco Systems Common
Stock in the Merger, the last reported sale prices on Nasdaq of the World Access
Common Stock and the Telco Systems Common Stock were $13 5/8 and $6 3/8,
respectively. If the World Access Market Price is less than $20.47 per share,
then World Access will be obligated to issue additional shares of World Access
Common Stock or pay additional cash amounts to the Telco Systems stockholders to
ensure that they receive Merger Consideration having the Minimum Nominal Value.
No assurance can be given as to the market price of World Access Common Stock if
and when the Merger is consummated. Telco Systems stockholders are urged to
obtain current market quotations for World Access Common Stock.
 
     Under the DGCL, holders of Telco Systems Common Stock will not be entitled
to dissenting stockholders' appraisal rights in connection with the Merger
unless World Access elects to include cash as a portion of the Merger
Consideration. In order to preserve such rights, Telco Systems stockholders must
take action prior to the Telco Systems Special Meeting. See "The
Merger -- Appraisal Rights."
 
     Following determination of the World Access Market Price and the portion of
the Merger Consideration that World Access has elected to pay in cash, which
will occur after the close of trading on the third business day prior to the
Effective Time, holders of Telco Systems Common Stock can obtain the World
Access Market Price, the approximate number of shares of World Access Common
Stock and the approximate amount of cash into which each share of Telco Systems
Common Stock will be converted in the Merger (subject to the 55% limitation
described above) by contacting either Georgeson & Company Inc. at (800) 223-2064
(toll free) or Corporate Investor Communications, Inc. at (800) 346-7885 (toll
free) (the "Information Agents"). This information also will be posted on the
world wide web sites of each of World Access (http://www.waxs.com) and Telco
Systems (http://www.telco.com). Proxies and revocation of proxies may be
delivered at any time prior to the taking of the vote at the special meeting to
which such proxy relates.
 
     This Joint Proxy Statement/Prospectus and the accompanying forms of proxy
are first being mailed to stockholders of World Access and Telco Systems on or
about November 10, 1998.

OVERVIEW OF THE MERGER
 
     In the Merger, Telco Systems will be merged with and into Merger Sub, with
Merger Sub continuing as the surviving corporation (the "Surviving Corporation")
and a direct wholly owned subsidiary of World Access, and the holders of Telco
Systems Common Stock will be entitled to receive the Merger Consideration. At
the Effective Time, each outstanding share of Telco Systems Common Stock
(together with the Associated Right) (other than (i) shares owned by Telco
Systems, World Access or Old World Access, which will be cancelled, and (ii)
shares held by persons who have perfected their appraisal rights (if applicable)
under Section 262 of the DGCL) will be converted into and become exchangeable
for that number of shares of World Access Common Stock equal to the quotient of
$17.00 divided by the World Access Market Price (unless the World Access Market
Price exceeds $36.00 per share, in which case each outstanding share of Telco
Systems Common Stock will be converted into .4722 shares of World Access Common
Stock, or unless the World Access Market Price is less than $29.00 per share, in
which case each outstanding share of Telco Systems Common Stock will be
converted into .5862 shares of World Access Common Stock), provided that (i) the
nominal value of the consideration to be received by holders of Telco Systems
Common Stock is no less than the Minimum Nominal Value and (ii) World Access may
elect to pay cash in lieu of issuing shares of World Access Common Stock so long
as such cash does not comprise more than 55% of the Merger Consideration (based
on the average of the high and low trading prices of the World Access Common
Stock on the day the Merger is consummated). If World Access elects to pay cash
in the Merger in lieu of issuing shares of World Access Common Stock, then each
share of Telco Systems Common Stock will be exchanged for a pro rata portion of
(i) the Aggregate Cash Pool (which is subject to the 55% limitation described
above) and (ii) the aggregate number of shares of World Access Common Stock to
be issued in the Merger, which will be equal to the number of shares of World
Access Common Stock that would have been issued in the Merger had World Access
not elected to include cash in the Merger Consideration less that number of such
shares having a value (based upon the World Access Market Price) equal to the
Aggregate Cash Pool. World Access will determine and publicly announce what
portion (if any) of the Merger Consideration it will pay in cash following the
close of trading on the third business day prior to the Effective Time. Also at
the Effective Time, each outstanding option to purchase Telco Systems Common
Stock will be assumed by World Access and converted into an option to purchase
shares of World Access Common Stock as adjusted to account for the Exchange
Ratio and the Minimum Nominal Value. See "The Merger" and "The Merger
Agreement."
 
     The following table sets forth the number of shares of World Access Common
Stock into which each share of Telco Systems Common Stock would be converted
upon consummation of the Merger at each of the hypothetical World Access Market
Prices set forth below assuming that none of the Merger Consideration is paid in
cash.

THE WORLD ACCESS SPECIAL MEETING
 
     Date and Place of the Meeting.  The World Access Special Meeting will be
held at the principal offices of World Access located at 945 E. Paces Ferry
Road, Suite 2240, Atlanta, Georgia 30326, on November 30, 1998, at 10:00 a.m.,
local time.
 
     Stockholders Entitled to Vote.  The record date for determination of
holders of World Access Common Stock entitled to vote at the World Access
Special Meeting is November 2, 1998 (the "World Access Record Date"). As of the
close of business on the World Access Record Date, 25,675,253 shares of World
Access Common Stock were outstanding, held by approximately 312 holders of
record. Only holders of record of World Access Common Stock as of the close of
business on the World Access Record Date are entitled to notice of and to vote
at the World Access Special Meeting and any adjournments or postponements
thereof.
 
     Purpose of the Meeting.  The purpose of the World Access Special Meeting is
to consider and vote upon proposals: (i) to approve and adopt the Merger
Agreement and the transactions contemplated thereby, including the Merger and
the Share Issuance; (ii) to approve an amendment to the Certificate of
Incorporation of World Access (the "World Access Certificate") to increase the
number of authorized shares of World Access Common Stock to 150,000,000; (iii)
to adopt the World Access, Inc. 1998 Incentive Equity Plan (the "Incentive
Equity Plan"); (iv) to ratify and approve Indemnification Agreements (the
Indemnification Agreements") with the directors and certain officers of World
Access; and (v) to transact such other business as may properly come before the
World Access Special Meeting or any adjournments or postponements thereof.
 
     Vote Required.  The presence, in person or by proxy, of a majority of the
aggregate number of shares of World Access Common Stock outstanding and entitled
to vote on the World Access Record Date is necessary to constitute a quorum at
the World Access Special Meeting. The approval of the Merger Agreement and the
transactions contemplated thereby, including the Merger and the Share Issuance,
the adoption of the Incentive Equity Plan and the ratification and approval of
the Indemnification Agreements will require the affirmative vote of a majority
of the shares of World Access Common Stock present in person or represented by
properly executed proxy at the World Access Special Meeting. The approval of the
amendment to the World Access Certificate will require the affirmative vote of a
majority of the outstanding shares of World Access Common Stock. See "The
Special Meetings -- The World Access Special Meeting -- Voting; Vote Required."
 
     Shares of World Access Common Stock that are voted "FOR," "AGAINST" or
"WITHHELD" at the World Access Special Meeting will be treated as being present
at such meeting for purposes of establishing a quorum and will also be treated
as votes eligible to be cast by the World Access Common Stock present in person
or represented by proxy at the World Access Special Meeting and entitled to vote
on the subject matter. Abstentions will be counted for purposes of determining
both the presence or absence of a quorum for the transaction of business and the
total number of votes cast with respect to a particular matter. Broker non-
votes will be counted for purposes of determining the presence or absence of a
quorum for the transaction of business but will not be counted for purposes of
determining the number of votes cast with respect to the particular proposal on
which the broker has expressly not voted. Broker non-votes with respect to
proposals set forth in this Joint Proxy Statement/Prospectus, other than with
respect to the approval of the amendment to the World Access Certificate, will
therefore not be considered votes cast and, accordingly, will not affect the
determination as to whether a majority of votes cast has been obtained with
respect to such matters. Because approval of the amendment to the World Access
Certificate will require the affirmative vote of a majority of the outstanding
shares of World Access Common Stock, broker non-votes with respect to such
proposal will have the same effect as a negative vote.
 
     Security Ownership by Management.  As of the close of business on the World
Access Record Date, directors and executive officers of World Access and their
respective affiliates may be deemed to be the beneficial owners of shares of
World Access Common Stock representing approximately 5.8% of the outstanding
voting power of World Access. Each of the directors and executive officers of
World Access has indicated that such person intends to vote or direct the vote
of all the shares of World Access Common Stock over which such person has voting
control in favor of the Merger Agreement and the transactions
                                        6
<PAGE>   18
 
contemplated thereby, including the Merger and the Share Issuance, and in favor
of all of the other proposals described herein.
 
THE TELCO SYSTEMS SPECIAL MEETING
 
     Date and Place of the Meeting.  The Telco Systems Special Meeting will be
held at the principal offices of Telco Systems located at 63 Nahatan Street,
Norwood, Massachusetts 02062 on November 30, 1998, at 10:00 a.m., local time.
 
     Stockholders Entitled to Vote.  The record date for determination of
holders of Telco Systems Common Stock entitled to vote at the Telco Systems
Special Meeting is November 6, 1998 (the "Telco Systems Record Date"). As of the
close of business on the Telco Systems Record Date, 11,942,598 shares of Telco
Systems Common Stock were outstanding, held by approximately 379 holders of
record. Only holders of record of Telco Systems Common Stock as of the close of
business on the Telco Systems Record Date are entitled to notice of and to vote
at the Telco Systems Special Meeting and any adjournments or postponements
thereof.
 
     Purpose of the Meeting.  The purpose of the Telco Systems Special Meeting
is to consider and vote upon proposals: (i) to approve and adopt the Merger
Agreement and the transactions contemplated thereby, including the Merger; and
(ii) to transact such other business as may properly come before the Telco
Systems Special Meeting or any adjournments or postponements thereof.
 
     Vote Required.  The approval of the Merger Agreement and the transactions
contemplated thereby, including the Merger, will require the affirmative vote of
a majority of the outstanding shares of Telco Systems Common Stock. See "The
Special Meetings -- The Telco Systems Special Meeting -- Voting; Vote Required."
 
     Shares of Telco Systems Common Stock that are voted "FOR," "AGAINST" or
"WITHHELD" at the Telco Systems Special Meeting will be treated as being present
at such meeting for purposes of establishing a quorum and will also be treated
as votes eligible to be cast by the Telco Systems Common Stock present in person
at the Telco Systems Special Meeting and entitled to vote on the subject matter.
Abstentions will be counted for purposes of determining both the presence or
absence of a quorum for the transaction of business and the total number of
votes cast with respect to a particular matter. Broker non-votes will be counted
for purposes of determining the presence or absence of a quorum for the
transaction of business but will not be counted for purposes of determining the
number of votes cast with respect to the particular proposal on which the broker
has expressly not voted. Abstentions and broker non-votes will have the same
effect as a vote against the approval of the Merger Agreement, which approval
will require the affirmative vote of a majority of the outstanding shares of
Telco Systems Common Stock.
 
     Security Ownership by Certain Beneficial Owners and Management.  As of the
close of business on the Telco Systems Record Date, directors and executive
officers of Telco Systems and their respective affiliates may be deemed to be
the beneficial owners of shares of Telco Systems Common Stock representing less
than 1% of the outstanding voting power of Telco Systems. Each of the directors
and executive officers of Telco Systems has indicated that such person intends
to vote or direct the vote of all the shares of Telco Systems Common Stock over
which such person has voting control in favor of the Merger Agreement and the
transactions contemplated thereby, including the Merger. In addition,
concurrently with the execution of the Merger Agreement, World Access and the
owners as of such date of approximately 8% of the outstanding Telco Systems
Common Stock (each a "Stockholder") entered into a Stockholders Proxy Agreement
pursuant to which each Stockholder granted to World Access the right to vote all
voting securities of Telco Systems held by such Stockholder in favor of the
Merger Agreement and the transactions contemplated thereby, including the
Merger. See "The Stockholders Proxy Agreement."
 
RECOMMENDATION OF THE WORLD ACCESS BOARD OF DIRECTORS
 
     The board of directors of World Access has unanimously approved and adopted
the Merger Agreement and the transactions contemplated thereby, including the
Merger and the Share Issuance, and unanimously
 
                                        7
<PAGE>   19
 
recommends that the stockholders of World Access vote FOR: (i) the approval and
adoption of the Merger Agreement and the consummation of the transactions
contemplated thereby, including the Merger and the Share Issuance; (ii) the
approval of the amendment to the World Access Certificate to increase the number
of authorized shares of World Access Common Stock to 150,000,000; (iii) the
adoption of the Incentive Equity Plan; and (iv) the ratification and approval of
the Indemnification Agreements. See "The Merger -- World Access Reasons for the
Merger; Recommendation of the World Access Board of Directors."
 
RECOMMENDATION OF THE TELCO SYSTEMS BOARD OF DIRECTORS
 
     The board of directors of Telco Systems has unanimously approved and
adopted the Merger Agreement and the transactions contemplated thereby,
including the Merger, and unanimously recommends that the stockholders of Telco
Systems vote FOR the approval and adoption of the Merger Agreement and the
consummation of the transactions contemplated thereby, including the Merger. See
"The Merger -- Telco Systems Reasons for the Merger; Recommendation of the Telco
Systems Board of Directors."
 
OPINION OF THE WORLD ACCESS FINANCIAL ADVISOR
 
     In making its recommendation with respect to the Merger, the board of
directors of World Access considered, among other things, the written opinion,
dated October 16, 1998, and confirmed in writing on October 27, 1998, of The
Robinson-Humphrey Company, LLC ("Robinson-Humphrey"), World Access' financial
advisor, to the effect that, based upon and subject to the various assumptions
and considerations set forth in such updated opinion, as of October 16, 1998,

financial point of view, to World Access. A copy of such opinion is attached to
this Joint Proxy Statement/Prospectus as Appendix B, and a copy of the
confirmation thereof is attached to this Joint Proxy Statement/Prospectus as
Appendix B-1. Robinson-Humphrey's opinion, which sets forth the assumptions

OPINION OF THE TELCO SYSTEMS FINANCIAL ADVISOR
 
     In making its recommendation with respect to the Merger, the board of
directors of Telco Systems considered, among other things, the written opinion,
dated October 26, 1998, of Broadview International LLC (formerly known as
Broadview Associates LLC, "Broadview"), Telco Systems' financial advisor, to the
effect that, as of October 26, 1998 and based upon and subject to the
assumptions, limitations and qualifications set forth in such opinion, the
Merger Consideration was fair, from a financial point of view, to the holders of
Telco Systems Common Stock. A copy of such opinion is attached to this Joint
Proxy Statement/Prospectus as Appendix C. Broadview's opinion, which sets forth
the assumptions made, procedures followed and matters considered by Broadview,
and the scope of Broadview's review, should be read carefully in its entirety.

THE MERGER
 
  Effective Time of the Merger
 
     As promptly as practicable after the satisfaction or waiver of the
conditions set forth in the Merger Agreement, the parties thereto will file a
certificate of merger with the Secretary of State of the State of Delaware. The
Merger will become effective upon such filing. See "The Merger
Agreement -- Effective Time."
 
  Conditions to the Merger
 
     Consummation of the Merger is subject to the satisfaction of certain
conditions, including (i) the approval and adoption of the Merger Agreement and
the transactions contemplated thereby, including the Merger, by the requisite
vote of the stockholders of Telco Systems; (ii) the approval of the Share
Issuance by the requisite vote of the stockholders of World Access; (iii) the
absence of any restrictive court orders or any
 
                                        8
<PAGE>   20
 
other legal restraints or prohibitions preventing or making illegal the
consummation of the Merger; (iv) the waiting period under the Hart-Scott-Rodino
Act of 1976, as amended (the "HSR Act"), having expired or been terminated; (v)
the continuing accuracy of the representations and warranties made in the Merger
Agreement at and as of the Effective Time; (vi) the receipt by World Access and
Telco Systems of opinions of counsel as to the tax-free nature of the Merger for
federal income tax purposes (except for cash in lieu of fractional shares and
except to the extent that Telco Systems stockholders receive cash if World
Access elects to pay a portion of the Merger Consideration in cash); and (vii)
the inclusion, subject to notice of issuance, in Nasdaq of the World Access
Common Stock to be issued in the Merger. The consummation of the Merger is also
subject to the World Access stockholders approving an increase in the number of
authorized shares of World Access Common Stock to 150,000,000 shares. See "The
Merger Agreement -- Conditions to the Merger" and "Additional Matters Submitted
to a Vote of World Access Stockholders -- Additional Proposal No. 1 -- Proposal
to amend Certificate of Incorporation of World Access to Increase the Number of
Authorized Shares of World Access Common Stock to 150,000,000."
 
  Termination; Termination Fees
 
     The Merger Agreement may be terminated and the Merger abandoned at any time
prior to the Effective Time, notwithstanding the adoption and approval of the
Merger Agreement and the transactions contemplated thereby by the stockholders
of World Access and the stockholders of Telco Systems, by mutual consent, if a
governmental order prevents consummation, if the Effective Time does not occur
on or before December 31, 1998, by World Access if Telco Systems withdraws,
modifies or changes its recommendation of the Merger in a manner adverse to
World Access, by Telco Systems if World Access withdraws, modifies or changes
its recommendation of the Merger in a manner adverse to Telco Systems, if the
vote at either special meeting is resolved adverse to the Merger, if any
material uncured breach of the Merger Agreement occurs, by World Access if the
board of directors of Telco Systems recommend to the stockholders a Competing
Transaction or if the board of directors of Telco Systems fails to recommend
against a tender offer for 15% or more of outstanding Telco Systems capital
stock, by Telco Systems if the board of directors of Telco Systems determines in
good faith, after consultation with outside counsel, that it is highly probable
that by failing to accept a Superior Proposal it would be violating its
fiduciary duties to the stockholders of Telco Systems or by World Access if the
World Access Market Price is less than $12.00 per share. However, in the event
of certain terminations of the Merger Agreement, Telco Systems or World Access
(as the case may be) would be required to pay to the other a termination fee of
$5,500,000 or, in certain circumstances, $2,000,000, plus all of the other
party's reasonable expenses not to exceed $1,000,000. In the event that World
Access terminates the Merger Agreement because the World Access Market Price is
less than $12.00 per share, Telco Systems would be required to pay to World
Access a termination fee of $1,000,000. See "The Merger Agreement --
Termination" and "-- Termination Fees and Expenses".
 
  Regulatory Matters
 
     Under the HSR Act, and the rules promulgated thereunder, the Merger may not
be consummated until notifications have been given and certain information has
been furnished to the Federal Trade Commission (the "FTC") and the Antitrust
Division of the United States Justice Department (the "Antitrust Division") and
specified waiting period requirements have been satisfied. The waiting period
applicable to the Merger under the HSR Act was terminated by the FTC on August
28, 1998. See "The Merger -- Regulatory Matters."
 
  Appraisal Rights
 
     Holders of World Access Common Stock are not entitled to appraisal rights
in connection with the Merger. Under Delaware law, if World Access pays a
portion of the Merger Consideration in cash, then a Telco Systems stockholder
would be entitled to certain appraisal rights if such stockholder complied with
certain requirements of Delaware law. See "The Merger -- Appraisal Rights."
 
  Interests of Certain Persons in the Merger
 
     A number of directors and officers of Telco Systems have interests in the
merger as employees and/or directors that are different from, or in addition to,
those of the Telco Systems stockholders generally. Certain
                                        9
<PAGE>   21
 
officers of Telco Systems will become officers of the Surviving Corporation.
Agreements exist between Telco Systems and certain of its executive officers
that would entitle them to cash severance payments as a result of a termination
of their employment following the Merger. Certain of these executive officers
have agreed to provisionally waive their rights to such severance payments in
exchange for a grant of World Access stock options. In addition, if the Merger
is completed, options to purchase Telco Systems Common Stock held by officers,
directors and employees of Telco Systems will automatically be converted into
options to acquire shares of World Access Common Stock adjusted to account for
the Exchange Ratio and the Minimum Nominal Value. Certain indemnification
arrangements and directors' and officers' liability insurance for existing
directors and officers of Telco Systems will be continued by World Access. The
Telco Systems board of directors was aware of these interests when it approved
the Merger. See "The Merger -- Interests of Certain Persons in the Merger."
 
  Accounting Treatment
 
     The Merger will be accounted for by World Access under the purchase method
of accounting for business combinations. See "The Merger -- Accounting
Treatment."
 
  Federal Income Tax Consequences
 
     The Merger will qualify as a tax-free reorganization under Section 368 of
the Internal Revenue Code of 1986, as amended (the "Code"). Accordingly, holders
of Telco Systems Common Stock will not recognize gain or loss for federal income
tax purposes by reason of the conversion of Telco Systems Common Stock into
World Access Common Stock, except in respect of cash received in lieu of
fractional shares, and gain will be recognized by Telco Systems stockholders to
the extent cash is received through World Access' election to pay a portion of
the Merger Consideration in cash. It is a condition to the obligation of World
Access and Telco Systems to consummate the Merger that they shall each have
received opinions from their respective tax counsel, which opinions shall not
have been withdrawn or modified in any material respect, to the effect that the
Merger will qualify as a tax-free reorganization under Section 368 of the Code
and that each of World Access, Merger Sub and Telco Systems will be a party to
the reorganization within the meaning of Section 368(b) of the Code. The Merger
will not have any tax consequences to World Access stockholders. See "The
Merger -- Federal Income Tax Consequences."
 
  Exchange of Share Certificates
 
     If the Merger becomes effective, World Access will mail a letter of
transmittal with instructions to all holders of record of Telco Systems Common
Stock as of the Effective Time for use in surrendering their stock certificates
in exchange for the Merger Consideration and a cash payment in lieu of
fractional shares. CERTIFICATES SHOULD NOT BE SURRENDERED UNTIL THE LETTER OF
TRANSMITTAL IS RECEIVED. See "The Merger -- Exchange of Shares."
 
  Operations Following the Merger
 
     Following the Merger, the Surviving Corporation initially will be managed
by the operating management of Telco Systems and will become the Transport and
Access Systems Group of World Access. Promptly following the Merger, World
Access intends to integrate the operations of its current Transport and Access
Systems Group into, and under the supervision of, the Surviving Corporation. The
Surviving Corporation will otherwise continue the operations of Telco Systems
substantially as such operations were conducted prior to the Merger. See "The
Merger -- Operations Following the Merger."
 
  Amendment to the Merger Agreement
 
     On October 13, 1998, World Access and Telco Systems announced that they had
agreed in principle to amend the Merger Agreement to, among other things,
establish the Minimum Nominal Value of $12.00 to be received by the holders of
Telco Systems Common Stock in the Merger and to provide World Access with an
option to pay a portion of the Merger Consideration in cash (subject to certain
limitations). On October 27,
 
                                       10
<PAGE>   22
 
1998, the companies executed the First Amendment to the Merger Agreement to
implement their agreement in principle (the "First Amendment").
 
  Recent World Access Developments
 
     On May 12, 1998, Old World Access announced that it had entered into (i) an
Agreement and Plan of Merger and Reorganization (the "Resurgens Merger
Agreement") with RCG, which is currently operating as a debtor in possession
under Chapter 11 of the Bankruptcy Code, pursuant to which World Access agreed
to acquire RCG in a merger transaction (the "RCG Merger"); and (ii) a Share
Exchange Agreement and Plan of Reorganization (the "Exchange Agreement") with
the sole shareholder (the "Shareholder") of Cherry U.K., pursuant to which World
Access agreed to acquire Cherry U.K. in a share exchange transaction (the
"Cherry Exchange").
 
     In connection with the RCG Merger, the creditors of RCG will receive an
aggregate of 9,375,000 shares of World Access Common Stock. Of the shares of
World Access Common Stock to be issued to the RCG creditors, one third will be
issued to the RCG creditors upon consummation of the RCG Merger and two-thirds
will be held in escrow and released to the RCG creditors over the two year
period following the consummation of the RCG Merger subject to the attainment of
certain performance criteria for Resurgens.
 
     In connection with the Cherry Exchange, the Shareholder will receive an
aggregate of 1,875,000 shares of World Access Common Stock, of which one-third
will be issued to the Shareholder upon consummation of the Exchange and the
remaining two-thirds will be issued and held in escrow and released to the
Shareholder over the two year period following the consummation of the Cherry
Exchange subject to the attainment of certain performance criteria for
Resurgens. The Exchange Agreement provides, however, that the number of shares
of World Access Common Stock to be received by the Shareholder will be reduced
to the extent that World Access is required to convert options to acquire shares
of Cherry U.K. capital stock, which options may only be granted with the
permission of World Access, into options to acquire World Access Common Stock.
It is currently expected that no such options will be granted.
 
     World Access intends to schedule a special meeting of its stockholders to
be held in December 1998 (the "Resurgens Special Meeting") to consider and vote
upon, among other things, a proposal to acquire Resurgens. World Access has
fixed November 3, 1998 as the record date for determining which World Access
stockholders are entitled to notice of and to vote at the Resurgens Special
Meeting. Accordingly, the stockholders of Telco Systems will not be entitled to
vote at such meeting.
 
     Each of the RCG Merger and the Cherry Exchange is subject to the
satisfaction of certain conditions customary in similar transactions, including
the approval of the stockholders of World Access. Finally, the consummation of
the RCG Merger is a condition to the consummation of the Cherry Exchange, and
the Cherry Exchange is a condition to the consummation of the RCG Merger. The
RCG Merger and the Cherry Exchange are collectively referred to herein as the
"Resurgens Transaction."
 
     Resurgens is a facilities-based provider of international network access,
commonly referred to in the industry as a carriers' carrier. Resurgens had
consolidated revenues of approximately $165.5 million for the year ended
December 31, 1997 and $10.4 million for the six months ended June 30, 1998 and
incurred a net loss of $171.7 million for the year ended December 31, 1997 and
$29.3 million for the six months ended June 30, 1998.

    respective dates of acquisition: 67.3% interest in NACT -- February 27,
    1998; Advanced TechCom, Inc. ("ATI") -- January 29, 1998; Galaxy Personal
    Communications Services, Inc. ("Galaxy") -- July 1, 1997; Cellular

    Inc. ("Sunrise") -- January 1, 1996; Westec Communications, Inc.
    ("Westec") -- October 2, 1995; and AIT, Inc. ("AIT") -- May 17, 1995. On a
    pro forma unaudited basis, as if the acquisition of the 67.3% interest in
    NACT and the acquisition of ATI had occurred as of January 1, 1997, World
    Access' total sales, net income and net income per diluted share for the
    year ended December 31, 1997 and six months ended June 30, 1998 would have
    been approximately $136,517,000 and $86,399,000; $7,069,000 and $6,428,000;
    and $0.34 and $0.29, respectively.
(2) Special charges in the first quarter of 1998 included $50.0 million for
    in-process research and development related to the first quarter 1998
    acquisition of a 67.3% interest in NACT and the acquisition of ATI. See Note
    2 to the consolidated financial statements of World Access for the quarter
    ended June 30, 1998. World Access expects to record an additional in-process
    research and development charge of approximately $22.0 million in the fourth
    quarter of 1998 in connection with the acquisition of the remaining 32.7% of
    NACT.
(3) Special charges in the first quarter of 1998 included $6.6 million for costs
    related to the consolidation of several operations and World Access' exit
    from the contract manufacturing business. The special charges included
    $3,360,000 to cost of sales for obsolete and redundant inventories and
    $3,240,000 for severance benefits, lease terminations, idle equipment and
    other phase-down expenses related to the consolidation program. See Note 6
    to the consolidated financial statements of World Access for the quarter
    ended June 30, 1998. Special charges in 1995 resulted primarily from a
    write-down of test equipment and related tooling used in the company's
    analog repair operations.
(4) World Access recorded no income tax expense during 1993 to 1995 due to net
    losses realized and the availability of federal income tax net operating
    loss carryforwards. See "World Access -- Management's Discussion and
    Analysis of Financial Condition and Results of Operations of World Access"
    and Note K to the consolidated financial statements of World Access for the
    year ended December 31, 1997 (the "World Access Consolidated Financial
    Statements").
(5) Weighted average shares outstanding exclude 1,204,000 and 995,000 shares of
    World Access Common Stock for the six months ended June 30, 1998 and the
    year ended December 31, 1997, respectively, that are held in escrow accounts
    established in connection with certain acquisitions and a license agreement.
    These shares were excluded because the conditions for release of such shares
    had not yet been satisfied. See Notes A, B, and E to the World Access
    Consolidated Financial Statements.
(6) In October 1997, World Access sold $115.0 million of convertible
    subordinated notes. See Note G to the World Access Consolidated Financial
    Statements.

                           COMPARATIVE PER SHARE DATA
 
     The following table sets forth certain historical per share data of World
Access and Telco Systems and combined per share data on an unaudited pro forma
basis after giving effect to the Merger, assuming that (i) the Merger
Consideration is comprised solely of approximately 6.5 million shares of World
Access Common Stock (valued at $20.47 per share), which results in an effective
Exchange Ratio of .5862; or (ii) the Merger Consideration is comprised of
approximately 2.9 million shares of World Access Common Stock (valued at $20.47
per share) and $73.4 million (representing 55% of the value of the aggregate
Merger Consideration) in cash, which results in an effective Exchange Ratio of
 .2638. The pro forma per share data of World Access is presented to give effect
to the Merger, the Resurgens Transaction and the acquisition of NACT and ATI.
The historical per share data of World Access presented below is presented as of
and for the fiscal year ended December 31, 1997 and for the six months ended
June 30, 1998. Telco Systems has a fiscal year end of August 30. The historical
per share data of Telco Systems is presented as of and for the fiscal year ended
August 30, 1998 and for the six month period ended August 30, 1998. This data
should be read in conjunction with the selected historical and pro forma
financial information, the unaudited pro forma combined financial statements and
the separate historical financial statements of World Access, Telco Systems,
Resurgens, NACT and ATI and the notes thereto included elsewhere herein. No
dividends were paid by World Access or Telco Systems during the periods
presented below.
 
     The unaudited pro forma per share data is presented for informational
purposes only and is not necessarily indicative of the financial position or
operating results that would have occurred if the transactions given retroactive
effect therein had been consummated as of the dates indicated, nor is it
necessarily indicative of the future financial condition or operating results.

(a)  Historical earnings per share data are presented on a diluted basis in
     accordance with SFAS No. 128.
(b)  Calculated by dividing historical stockholders' equity by the number of
     outstanding common shares. The outstanding common shares do not include
     shares issuable upon exercise of stock options or conversion of outstanding
     convertible securities.
(c)  The comparative per share data does not give effect to Telco Systems'
     acquisition of Synaptyx Corporation ("Synaptyx") in October 1998 pursuant
     to which Telco Systems issued approximately 576,000 shares of Telco Systems
     Common Stock, placed in escrow an additional approximately 204,000 shares
     of Telco Systems Common Stock, the release of which is subject to achieving
     certain operating performance criteria, and issued options to acquire
     approximately 368,000 shares of Telco Systems Common Stock. As a
     consequence of this transaction, World Access will be required in the
     Merger (i) to issue an additional approximately 457,000 shares of World
     Access Common Stock and options to acquire approximately 216,000 shares of
     World Access Common Stock (assuming that the Merger Consideration is
     comprised solely of shares of World Access Common Stock) or (ii) to issue
     an additional approximately 206,000 shares of World Access Common Stock and
     options to acquire approximately 216,000 shares of World Access Common
     Stock and pay approximately $5.1 million in cash (assuming that 55% of the
     Merger Consideration is comprised of cash). The acquisition of Synaptyx
     does not meet any of the materiality thresholds that would require it to be
     given pro forma effect in this Joint Proxy Statement/Prospectus.
(d)  Calculated by dividing pro forma stockholders' equity by the number of
     outstanding common shares expected to be outstanding as of the consummation
     of the Merger, the Resurgens Transaction and the acquisition of NACT and
     ATI, which number does not include shares issuable upon the exercise of
     stock options of the conversion of outstanding convertible securities.

                                  RISK FACTORS
 
     Holders of World Access Common Stock and holders of Telco Systems Common
Stock, in evaluating whether to approve the Merger Agreement and the
transactions contemplated thereby, should carefully consider the following risk
factors, in addition to the other information included in this Joint Proxy
Statement/Prospectus. Other than statements of historical fact, statements
contained in this Joint Proxy Statement/Prospectus, including statements as to
the benefits expected to be realized as a result of the Merger and as to future
financial performance, constitute forward-looking statements. Actual results of
World Access may differ significantly from the results discussed in the
forward-looking statements contained in this Joint Proxy Statement/Prospectus.
Factors that might cause such a difference include, but are not limited to,
those discussed below. Holders of Telco Systems Common Stock and World Access
Common Stock are cautioned not to place undue reliance on the forward-looking
statements contained in this Joint Proxy Statement/Prospectus, which speak only
as of the date hereof. Neither World Access nor Telco Systems undertakes any
obligation to publicly release the results of any revisions to such
forward-looking statements which may be made to reflect events or circumstances
after the date hereof or to reflect the occurrence of unanticipated events.
 
RISK FACTORS CONCERNING THE MERGER
 
     Potential Effects of the Merger.  The success of the Merger will depend on
many factors, including the achievement of certain operating efficiencies.
Failure to successfully achieve any of such efficiencies, including a delay in
attaining them, could adversely effect the business, financial condition and
results of operations of World Access. See "-- Potential Fluctuations in
Quarterly Operating Results."
 
     In addition, there can be no assurance that the combining of the two
companies' businesses will result in combined results of operations superior to
what would have been achieved by each company independently or that stockholders
of World Access and Telco Systems would not achieve greater returns on
investment if the Merger were not to occur. See "The Merger -- Background of the
Merger," "-- World Access Reasons for the Merger; Recommendation of the World
Access Board of Directors," and "-- Telco Systems Reasons for the Merger;
Recommendation of the Telco Systems Board of Directors."
 
     Management of Growth.  World Access is currently experiencing a period of
rapid growth resulting from recent acquisitions and the expansion of its
operations, both of which have placed significant demands on its resources. The
success of World Access in managing its growth will require it to continue to
improve its operational, financial and management information systems and to
motivate and effectively manage its employees. If management of World Access is
unable to manage such growth effectively, the quality of the World Access
products and services, its ability to retain key personnel and its business,
financial condition and results of operations could be materially adversely
affected.
 
RISK FACTORS CONCERNING WORLD ACCESS AND TELCO SYSTEMS
 
     Compliance with Government Regulations and Evolving Industry
Standards.  Each company's products and services must meet a significant number
of voice and data communications regulations and standards, some of which are
evolving as new technologies are deployed. In the United States, these products
and services must comply with various regulations promulgated by the Federal
Communications Commission ("FCC"), as well as with standards established by Bell
Communications Research ("BellCore"). Internationally, these products and
services must comply with standards established by telecommunications
authorities in various countries, as well as with recommendations of the
International Telecommunications Union ("ITU"). In addition, telecommunications
service providers require that equipment connected to their networks comply with
their own standards, which may vary from industry standards. Certain regulations
currently require that products which reside on a customer's premises and
interconnect the public switched network meet certain standards to prevent harm
to the network. Other regulations currently limit the levels of electromagnetic
radiation which may emanate from an electronic device located on a customer's
premises. The failure of either company's products to comply, or delays or costs
in achieving compliance, with the
 
                                       25
<PAGE>   37
 
various existing and evolving regulations and industry standards could have a
material adverse effect on its business, financial condition and results of
operations.
 
     The companies expect that government regulatory policies, including the
Telecommunications Act of 1996, are likely to continue to have a major impact on
the pricing of both existing and new public network services and possibly
accelerate the entrance of new competitors and consolidation of industry
participants and, therefore, are expected to affect supply and demand for such
services and the telecommunications products that support such services. Tariff
rates, whether determined autonomously by telecommunications service providers
or in response to regulatory directives, may affect the cost-effectiveness of
deploying public network services. Tariff policies are under continuous review
and are subject to change. User uncertainty regarding future policies may also
affect demand for telecommunications products and services, including each
company's products and services.
 
     Potential Fluctuations in Quarterly Operating Results.  Each company's
quarterly operating results have varied significantly in the past and are
expected to do so in the future. As each company increases the number of its
telecommunications product and service offerings, its future quarterly operating
results may vary significantly depending on factors such as the timing and
shipment of significant orders, new product and service introductions by it and
its competitors, market acceptance of new and enhanced versions of its products
and services, changes in pricing policies by it and its competitors, the
availability of new technologies, the mix of distribution channels through which
its products and services are sold, the inability to obtain sufficient supplies
of sole or limited source components for its products, gains or losses of
significant customers, the timing of customers' upgrade and expansion programs,
changes in the level of operating expenses, the timing of acquisitions,
seasonality and general economic conditions. In response to competitive
pressures for new product and service introductions, each company may take
certain pricing or marketing actions that could materially and adversely affect
its quarterly operating results. Accordingly, each company believes that period-
to-period comparisons of its operating results should not be relied upon as an
indication of future performance. In addition, the operating results of any
quarterly period are not indicative of results to be expected for a full fiscal
year. Historically, each company also has generated a disproportionate amount of
its operating revenues toward the end of each quarter, making precise prediction
of revenues and earnings particularly difficult and resulting in risk of
variance of actual results from those forecast at any time.
 
     Due to all of the foregoing factors, it is possible that in some future
quarter each company's results of operations could be below prior results or the
expectations of market analysts and investors. In such an event, the price of
each company's stock would likely be materially adversely affected.
 
     The expense levels of World Access are based, in part, on its expectation
as to future sales. If future sales levels are below expectations, then World
Access may be unable to adjust spending sufficiently in a timely manner to
compensate for the unexpected sales shortfall.
 
     Rapid Technological Development; New Products and Services; Product
Errors.  The market for each company's products and services is generally
characterized by rapidly changing technology, evolving industry standards and
frequent new product and service introductions that can render existing products
and services obsolete or unmarketable. Each company's success will depend to a
substantial degree upon its ability to develop and introduce in a timely fashion
enhancements to its existing products and services and new products and services
that meet changing customer requirements and emerging industry standards. The
failure of either company to introduce new products and services and respond to
industry changes on a timely and cost effective basis could make inventory on
hand obsolete and could have a material adverse effect on such company's
business, financial condition and results of operations.
 
     The development of new, technologically advanced products and services is a
complex and uncertain process requiring high levels of innovation and capital,
as well as the accurate anticipation of technological and market trends. The
introduction and marketing of new or enhanced products and services require
management of the transition from existing products and services in order to
minimize disruption in customer purchasing patterns. There can be no assurance
that either company will successfully manage the transition to new or enhanced
products and services. Further, there can be no assurance that products,
services or technologies developed by others will not render either company's
products, services or technologies obsolete.
                                       26
<PAGE>   38
 
     Products as complex as those offered by each company may contain undetected
errors or failures when first introduced or as new versions are released, and
such errors have occurred in these products in the past. There can be no
assurance that, despite testing by each company and by current and potential
customers, errors will not be found in new products after commencement of
commercial shipments. The occurrence of such errors could result in the loss or
delay in market acceptance of products, diversion of development resources,
damage to company reputation or increased service or warranty costs, any of
which could have a material adverse effect upon each company's business,
financial condition and results of operations.
 
     From time to time, each company or its competitors may announce new
products, services, capabilities or technologies that have the potential to
replace or shorten the life cycle of its existing product and service offerings.
There can be no assurance that announcements of product enhancements or new
product or service offerings will not cause customers to defer or cancel
purchasing existing products and services or cause resellers to return products.
Any such deferrals, cancellations or returns could have a material adverse
effect on such company's business, operating results and financial condition.
 
     Failure to introduce new products and services or product or service
enhancements effectively and on a timely basis, customer delays in purchasing
products and services in anticipation of new product or service introductions
and any inability of either company to respond effectively to technological
changes, emerging industry standards or product and service announcements by
competitors could have a material adverse effect on such company's business,
operating results and financial condition.
 
     Limited Protection of Proprietary Rights.  Each company relies on
contractual rights, trade secrets, trademarks and copyrights to establish and
protect its proprietary rights in its products. Although each company presently
holds several patents for certain of its existing products and has several
patent applications pending, not all of its products are covered by patents. The
telecommunications equipment industry is characterized by the existence of a
large number of patents and frequent litigation based on allegations of patent
infringement. Neither company has conducted a formal patent search relating
generally to the technology used in its products. In addition, since patent
applications in the United States are not publicly disclosed until the patent
issues and foreign patent applications generally are not publicly disclosed for
at least a portion of the time that they are pending, applications may have been
filed which, if issued as patents, would relate to either company's products. In
addition, software comprises a substantial portion of the technology in each
company's products. The scope of protection accorded to patents covering
software-related inventions is evolving and is subject to a degree of
uncertainty that may increase the risk and cost to either of the companies if it
discovers the existence of third party patents related to its software products
or if such patents are asserted against it in the future.
 
     In the future, each company may be required to bring or defend against
litigation to enforce any patents issued or assigned to it, to protect
trademarks, trade secrets and other intellectual property rights owned by it, to
defend it against claimed infringement of the rights of others and to determine
the scope and validity of the proprietary rights of others. Regardless of the
ultimate outcome, any litigation could be costly and could divert management's
attention, which could have a material adverse effect on the business, financial
condition and results of operations of such company. Adverse determinations in
litigation could result in the loss of the proprietary rights of such company,
subject it to significant liabilities, require it to seek licenses from third
parties or prevent it from manufacturing or selling its products, any of which
could have a material adverse effect on the business, financial condition and
results of operations of such company.
 
     Dependence on Key Personnel.  Each company is highly dependent on the
services of several key executive officers and technical employees, the loss of
any of whom could have a material adverse effect on its business, financial
condition and results of operations. In addition, each company will need to hire
additional skilled personnel to support the continued growth of its business.
The market for skilled personnel, especially those with the technical abilities
required by each company, is currently very competitive, and each company must
compete with much larger companies with significantly greater resources to
attract and retain such personnel.
 
     Competition.  The segments of the telecommunications industry in which the
companies operate are intensely competitive. Many of each company's competitors
have significantly more extensive engineering,
                                       27
<PAGE>   39
 
manufacturing, marketing, financial and technical resources than such company.
In addition, several major suppliers may compete with one or both of the
companies, such as Northern Telecom's current relationship with World Access,
with respect to the sale of certain of their products, which may adversely
affect their ability to continue to obtain such products from these suppliers in
the future.
 
     The companies may face additional competition from the Regional Bell
Operating Companies ("RBOCs"), which have historically been prohibited from
manufacturing telecommunications equipment by the terms of the Modification of
Final Judgment entered into in connection with the divestiture of the RBOCs by
AT&T in 1984. The Telecommunications Act of 1996 contains provisions that permit
the RBOCs, subject to satisfying certain conditions designed to facilitate local
exchange competition, to manufacture telecommunications equipment. In light of
these provisions, it is possible that one or more of the RBOCs, some of which
are major customers of World Access and Telco Systems, may decide to manufacture
telecommunications equipment or to form alliances with other manufacturers. Any
of these developments could result in increased competition for each company,
which may have a material adverse effect on its business, financial condition
and results of operations.
 
RISK FACTORS CONCERNING WORLD ACCESS
 
     Acquisition Risks.  An element of the World Access strategy for the future
is expansion through the acquisition of companies that complement or expand its
existing businesses. Acquisitions involve a number of special risks, including
the time associated with identifying and evaluating future acquisitions, the
diversion of management's attention to the integration of the operations and
personnel of the acquired companies, the integration of acquired products and
services, possible adverse short-term effects on the operating results of World
Access, the realization of acquired intangible assets and the loss of key
employees of the acquired companies. World Access may issue equity securities
and other forms of consideration in connection with future acquisitions, which
could cause dilution to the then-existing stockholders of World Access. World
Access does not currently have any commitments or agreements with respect to any
acquisitions other than the Merger Agreement, the Resurgens Merger Agreement and
the Exchange Agreement. There can be no assurance that suitable acquisition
candidates will be found upon terms acceptable to World Access, that World
Access will have adequate resources to consummate any acquisition, that
acquisitions can be consummated successfully, or that acquired businesses will
be operated profitably or integrated successfully into the operations of World
Access.
 
     Increased Leverage.  In connection with the October 1997 sale of the World
Access 4.5% Convertible Subordinated Notes, World Access incurred approximately
$115.0 million in additional indebtedness, which significantly increased the
ratio of its long-term debt to its total capitalization from 0.3% at September
30, 1997 to 57.3% on a pro forma basis. As a result of this increased leverage,
the principal and interest obligations of World Access increased substantially.
The degree to which World Access is leveraged could adversely affect its ability
to obtain additional financing for working capital, acquisitions or other
purposes and could make it more vulnerable to economic downturns and competitive
pressures. The increased leverage of World Access could also adversely affect
its liquidity, as a substantial portion of available cash from operations may
have to be applied to meet debt service requirements and, in the event of a cash
shortfall, World Access could be forced to reduce other expenditures and forego
potential acquisitions to be able to meet such requirements.
 
     Holding Company Risks.  As a holding company without significant income
from operations, World Access is dependent upon the income from its operating
subsidiaries to meet its operating expenses. If World Access' operating
subsidiaries are unable to pay dividends or otherwise distribute amounts to
World Access sufficient to cover its operating expenses, then World Access may
be subject to liquidity problems, even if, on a consolidated basis, its
operating subsidiaries are profitable.
 
     Dependence on Suppliers.  World Access purchases substantially all of its
components and other parts from suppliers on a purchase order basis and does not
maintain long-term supply arrangements. Several components, primarily custom
hybrid integrated circuits, are available from a single source. In addition, the
operations of certain of the World Access subsidiaries depend on a consistent
supply of new or used switching products, add-on frames and related circuit
boards. Accordingly, there can be no assurance that World Access
 
                                       28
<PAGE>   40
 
will be able to continue to obtain sufficient quantities of products or key
components as required or that such products or key components, if obtained,
will be available to World Access on commercially favorable terms. Failure to
obtain key products and key components on a timely and cost effective basis
could have a material adverse effect on the business, financial condition and
results of operations of World Access.
 
     Customer Concentration.  A small number of customers historically has
accounted for a significant percentage of World Access' and NACT's total sales.
For the six months ended June 30, 1998 and the year ended December 31, 1997, no
customer individually accounted for more than 10% of World Access' total sales
and World Access' top 10 customers accounted for 39.5% and 44.2% of total sales,
respectively. For the six months ended June 30, 1998 and the year ended
September 30, 1997, NACT's top 10 customers accounted for 44.7% and 55.7% of
total sales, respectively. JD Services, Inc. accounted for 11% of NACT's total
sales during the six months ended June 30, 1998, and no customer individually
accounted for more than 10% of NACT's total sales for the year ended September
30, 1997. World Access' and NACT's customers typically are not obligated
contractually to purchase any quantity of products or services in any particular
period. The loss of, or a material reduction in orders by, one or more of World
Access' or NACT's key customers could have a material adverse effect on World
Access' business, financial condition and results of operations.
 
     For the year ended December 31, 1997, PT-1 Communications Incorporated
accounted for 21% of Resurgens' total sales. In addition, Resurgens' revenues
attributable to its Carrier Service Agreement with WorldCom Network Services,
Inc. ("WNS"), a wholly owned subsidiary of MCI WorldCom, Inc., for the month of
September 1998 comprised approximately 50% of Resurgens' total revenues for such
period, and Resurgens' revenues attributable to WNS comprised approximately 54%
of Resurgens' total revenues for the nine month period ended September 30, 1998.
If the Resurgens Transaction is consummated, then the loss of, or a material
reduction in orders, by, such a key customer of Resurgens could have a material
adverse effect on World Access' business, financial condition and results of
operations.
 
      International Sales; Regulatory Standards; Currency Exchange.
International sales represented approximately 22.4% of World Access' total sales
for the six months ended June 30, 1998 and 11.3%, 1.7% and 5.0% of total sales
in the years ended December 31, 1997, 1996 and 1995, respectively. International
sales represented approximately 8.7% of NACT's total sales for the six months
ended June 30, 1998 and 14.3%, 12.9% and 6.4% of total sales in the years ended
September 30, 1997, 1996 and 1995, respectively. World Access intends to
increase its international sales efforts, which may require significant
management attention and financial resources. There can be no assurance that
World Access can increase its international sales. International sales are
subject to inherent risks, including unexpected changes in regulatory
requirements, tariffs or other barriers, difficulties in staffing and managing
foreign operations, longer payment cycles, unstable political environments,
greater difficulty in accounts receivable collection and potentially adverse tax
consequences. Moreover, gains and losses on the conversion to U.S. dollars of
receivables and payables arising from international operations may contribute to
fluctuations in World Access' results of operations, and fluctuations in
exchange rates could affect demand for World Access' products and services.
 
     Possible Volatility of Stock Price.  World Access believes factors such as
announcements of new products or technological innovations by World Access, or
third parties, as well as variations in World Access' results of operations, the
gain or loss of significant customers, the timing of acquisitions of businesses
or technology licenses, legislative or regulatory changes, general trends in the
industry, market conditions, analysts' estimates and other events or factors may
cause the market price of the World Access Common Stock to fluctuate
significantly. In addition, the stock market has experienced extreme price and
volume fluctuations that have particularly affected the market price for many
technology companies and that have often been unrelated to the operating
performance of these companies. These broad market fluctuations may adversely
affect the market price of the World Access Common Stock.
 
     Anti-Takeover Provisions.  Certain provisions of the World Access
Certificate, the World Access Bylaws and the DGCL could, together or separately,
discourage potential acquisition proposals or delay or prevent a change in
control of World Access. Currently, those provisions include a classified board
of directors, a prohibition on written consents in lieu of meetings of the
stockholders and the authorization to issue up to 10,000,000 shares of preferred
stock and up to 40,000,000 shares of World Access Common Stock. World

Access is submitting herewith to its stockholders a proposal to increase the
authorized shares of World Access Common Stock to 150,000,000. See "Additional
Matters Submitted to a Vote of World Access Stockholders -- Additional Proposal
1 -- Proposal to amend Certificate of Incorporation of World Access to Increase
the Number of Authorized Shares of World Access Common Stock to 150,000,000."
The World Access board of directors has the power to issue any or all of these
additional shares without stockholder approval, and the preferred shares can be
issued with such rights, preferences and limitations as may be determined by the
board of directors. The rights of the holders of World Access Common Stock will
be subject to, and may be adversely affected by, the commitments or contracts to
issue any additional shares of World Access Common Stock or any shares of
preferred stock. Authorized and unissued preferred stock and World Access Common
Stock, while providing desirable flexibility in connection with possible
acquisitions and other corporate purposes, could delay, discourage, hinder or
preclude an unsolicited acquisition of World Access, could make it less likely
that its stockholders receive a premium for their shares as a result of any such
attempt and could adversely affect the market price of, and the voting and other
rights of, the holders of outstanding shares of World Access Common Stock.
 
     Year 2000 Issue.  As a result of certain computer programs being written
using two digits rather than four to define the applicable year, any of World
Access' computer systems that have date sensitive software may recognize a date
using "00" as the year 1900 rather than the year 2000 (the "Year 2000 Issue").
This causes programs that perform arithmetic operations, comparisons or date
sorts to possibly generate erroneous results when the program is required to
process dates from both centuries. This could result in a system failure,
incorrect data and other business disruptions, including, among other things, a
temporary inability to procure materials, process transactions, send invoices
and service customers.
 
     World Access is in the process of evaluating its operating systems to
determine what modifications are necessary to make such systems compatible with
the year 2000 requirements. These systems include business information systems,
development tools and test beds, and manufacturing equipment and processes.
World Access has recently implemented a new business information system at
several of its locations that is certified to be year 2000 compliant by its
supplier. Independent tests by World Access have verified this compliance and
the system is expected to be deployed company-wide by mid-1999. World Access
plans on engaging an outside consulting firm in November 1998 to perform a
detailed year 2000 review of its development and manufacturing systems. The
costs to ensure compliance of these systems (including computer equipment,
software upgrades and assessment fees) by mid-1999 is currently estimated at
approximately $700,000.
 
     In addition, World Access is in the process of developing a plan whereby it
will review the year 2000 readiness of its customers and suppliers. In doing so,
it will undertake appropriate internal reviews and will contact certain of its
significant customers to assess, to the extent possible, Year 2000 Issues
related to World Access' products. In that regard, World Access has identified
that certain of its products, including NACT's NTS 1000 Billing System, are not
year 2000 compliant. NACT is in the process of modifying the NTS 1000 Billing
System to overcome the two digit limitation. This modification of the NTS 1000
software is anticipated to be completed by the first calendar quarter in 1999 at
an estimated cost of $115,000. World Access is in the process of releasing new
versions of such products and making necessary modifications to existing
products to address the Year 2000 Issue. World Access expects that many of its
customers will upgrade to the new products. However, there can be no assurance
that World Access customers will upgrade to the new year 2000 compliant products
or that the modifications planned to the certain of the existing products will
be successful or completed in a timely manner. Although World Access believes
that it can address year 2000 readiness issues related to its products, there
may still be disruptions and/or product failures that are unforeseen.
 
     World Access also intends to request assurances from its major suppliers
that they are addressing the Year 2000 Issue and that the products and services
procured or used by World Access will function properly or be available without
interruption in the year 2000. A detailed questionnaire was mailed to all major
suppliers in September 1998. Appropriate Year 2000 warranties will be requested
from key suppliers to World Access. Nevertheless, it will be impossible to fully
assess the potential consequences if service interruptions occur from suppliers
or in infrastructure areas such as utilities, communications, transportation,
banking and government. As a result, World Access also intends to develop a
business continuity plan by mid-1999 to minimize the impact of such external
events.

     While World Access' efforts to address Year 2000 Issues will involve
additional costs and the time and effort of a number of employees, World Access
believes, based on currently available information, that it will be able to
properly manage its total year 2000 exposure. There can be no assurance,
however, that World Access will be successful in its effort or that the computer
systems of other companies on which World Access will rely will be timely
modified, or that a failure to modify such systems by another company, or
modifications that are incompatible with World Access' systems, would not have a
material adverse effect on World Access' business, financial condition or
results of operations.
 
RISK FACTORS CONCERNING TELCO SYSTEMS
 
     Orders and Backlog.  Order delays and cancellations could have a material
adverse effect on the business, financial condition and results of operations of
Telco Systems. The customers of Telco Systems may revise scheduled delivery
dates, product configuration or cancel orders. Telco Systems' backlog of orders
may not mitigate the effect of such delays and cancellations. The backlog may
not be representative of actual sales for any succeeding period because of the
timing of orders, delivery intervals, customer and product mix, the possibility
of changes in delivery schedules and additions or cancellation of orders.
 
     Dependence on Suppliers.  Telco Systems is dependent on a few suppliers to
provide certain custom-designed components, and any significant interruption in
the supply, or degradation in the quality, of components manufactured by such
suppliers could have a material adverse effect on the business, financial
condition and results of operations of Telco Systems. On-time delivery of Telco
Systems' products depends upon the availability of components manufactured by
suppliers and used in the products of Telco Systems. There can be no assurance
that such suppliers will continue to be able and willing to meet the
requirements of Telco Systems for any such components.
 
     Telco Systems has recently begun to rely on three contract manufacturers,
Eltech Electronics, Inc., US Assemblies, New England, Inc. and SCI Technologies,
Inc. to produce its products. Delivery of Telco Systems' products by such
manufacturers may be interrupted if the manufacturers encounter production,
quality or financial problems. Moreover, Telco Systems may fail to order
sufficient quantities of its products from the manufacturers to satisfy orders
from the customers of Telco Systems. Such interruptions or failures could have a
material adverse effect on the business, financial condition and results of
operations of Telco Systems.
 
     Concentration of Customers.  Recent merger activity among some of the large
customers of Telco Systems could have a material adverse effect on the future
orders of Telco Systems as those customers reassess their strategic direction.
NYNEX Corporation ("NYNEX"), the largest customer of Telco Systems, recently
merged with Bell Atlantic Corporation. A material curtailment by Bell Atlantic
Corporation in the rate at which NYNEX Corporation ordered products from Telco
Systems, if not offset by increased sales to other customers of Telco Systems,
would reduce the revenues of Telco Systems so that Telco Systems could not cover
its current level of operating costs, having a material adverse effect on the
business, financial condition and results of operations of Telco Systems.
 
     Telco Systems is dependent for a significant amount of its sales upon
NYNEX, Walker and Associates and Sprint Corporation, which represented
approximately 36%, 12% and 12%, respectively, of Telco Systems' sales for fiscal
1998 and 33%, 10% and 9%, respectively, for fiscal 1997. GTE Corporation
represented approximately 6% and 4% of Telco Systems' sales for fiscal 1998 and
1997, respectively. If the proposed merger of GTE Corporation and Bell Atlantic
Corporation (successor to NYNEX) is completed, then on a pro forma basis, the
combined entity would have represented approximately 42% and 37% of Telco
Systems' sales for fiscal years 1998 and 1997, respectively.
 
     The loss of, or a material reduction in orders by, one or more of the
significant customers of Telco Systems could have a material adverse effect on
the business, financial condition and results of operations of Telco Systems.

     Entry into International Markets.  Telco Systems has targeted the entry
into the international marketplace as an important part of its growth strategy.
International sales accounted for approximately 12% of Telco Systems' total
sales for fiscal 1998, up from 7% of its total sales for fiscal 1997 and 4% of
its total sales for fiscal 1996. International sales are subject to inherent
risks, including unexpected changes in regulatory requirements, tariffs or other
barriers, difficulties in staffing and managing foreign operations, longer
payment cycles, unstable political environments, greater difficulty in accounts
receivable collection and potentially adverse tax consequences. Also, to the
extent that any of Telco Systems' sales are denominated in foreign currencies,
Telco Systems' revenues and results of operations may also be directly affected
by fluctuations in foreign currency exchange rates.

                              THE SPECIAL MEETINGS
 
THE WORLD ACCESS SPECIAL MEETING
 
     General.  This Joint Proxy Statement/Prospectus is being furnished to
stockholders of World Access in connection with the solicitation of proxies by
the board of directors of World Access for use at the World Access Special
Meeting to be held at the principal offices of World Access located at 945 E.
Paces Ferry Road, Suite 2240, Atlanta, Georgia 30326, on November 30, 1998, at
10:00 a.m., local time, and at any adjournments or postponements thereof, for
the purposes set forth herein and in the accompanying notice of special meeting
of stockholders of World Access.
 
     Matters to Be Considered.  At the World Access Special Meeting,
stockholders of record of World Access as of the close of business on the World
Access Record Date will be asked to consider and vote upon proposals: (i) to
approve and adopt the Merger Agreement and the consummation of the transactions
contemplated thereby, including the Merger and the Share Issuance; (ii) to
approve an amendment to the World Access Certificate to increase the number of
authorized shares of World Access Common Stock to 150,000,000; (iii) to adopt
the Incentive Equity Plan; (iv) to ratify and approve the Indemnification
Agreements; and (v) to transact such other business as may properly come before
the World Access Special Meeting or any adjournments or postponements thereof.
 
     Board of Directors' Recommendation.  THE BOARD OF DIRECTORS OF WORLD ACCESS
HAS DETERMINED THAT THE MERGER IS FAIR TO, AND IN THE BEST INTERESTS OF, THE
STOCKHOLDERS OF WORLD ACCESS AND HAS THEREFORE UNANIMOUSLY APPROVED AND ADOPTED
THE MERGER AGREEMENT AND THE CONSUMMATION OF THE TRANSACTIONS CONTEMPLATED
THEREBY, INCLUDING THE MERGER AND THE SHARE ISSUANCE, AND UNANIMOUSLY RECOMMENDS
THAT THE STOCKHOLDERS OF WORLD ACCESS VOTE FOR: (I) THE APPROVAL AND ADOPTION OF
THE MERGER AGREEMENT AND THE CONSUMMATION OF THE TRANSACTIONS CONTEMPLATED
THEREBY, INCLUDING THE MERGER AND THE SHARE ISSUANCE; (II) THE APPROVAL OF THE
AMENDMENT TO THE WORLD ACCESS CERTIFICATE; (III) THE ADOPTION OF THE INCENTIVE
EQUITY PLAN; AND (IV) THE RATIFICATION AND APPROVAL OF THE INDEMNIFICATION
AGREEMENTS.
 
     World Access Record Date.  The board of directors of World Access has fixed
November 2, 1998 as the record date for determination of holders of World Access
Common Stock entitled to notice of and to vote at the World Access Special
Meeting. As of the close of business on the World Access Record Date, 25,675,253
shares of World Access Common Stock were outstanding, held by approximately 312
holders of record. Only holders of record of World Access Common Stock as of the
close of business on the World Access Record Date are entitled to notice of and
to vote at the World Access Special Meeting and any adjournments or
postponements thereof.
 
     Voting; Vote Required.  Each holder of record of World Access Common Stock
on the World Access Record Date is entitled to cast one vote per share of World
Access Common Stock held thereby on the World Access Record Date, exercisable in
person or by properly executed proxy, on each matter properly submitted for the
vote of the stockholders of World Access at the World Access Special Meeting. A
majority of the shares of World Access Common Stock entitled to vote at the
World Access Special Meeting will constitute a quorum for the transaction of
business at the World Access Special Meeting.
 
     The approval of the Merger Agreement, including the Merger and the Share
Issuance, the adoption of the Incentive Equity Plan and the ratification and
approval of the Indemnification Agreements each will require the affirmative
vote of a majority of the shares of World Access Common Stock, present in person
or represented by properly executed proxy at the World Access Special Meeting.
The approval of the amendment to the World Access Certificate will require the
affirmative vote of a majority of the outstanding shares of World Access Common
Stock.
 
     Shares of World Access Common Stock that are voted "FOR," "AGAINST" or
"WITHHELD" at the World Access Special Meeting will be treated as being present
at such meeting for purposes of establishing a quorum and will also be treated
as votes eligible to be cast by the World Access Common Stock present in person
or represented by proxy at the World Access Special Meeting and entitled to vote
on the subject matter. Abstentions will be counted for purposes of determining
both the presence or absence of a quorum for
 
                                       33
<PAGE>   45
 
the transaction of business and the total number of votes cast with respect to a
particular matter. Broker non-votes (i.e., shares identified as held by brokers
or nominees as to which instructions have not been received from the beneficial
owners or persons entitled to vote that the broker or nominee does not have
discretionary power to vote on a particular matter) will be counted for purposes
of determining the presence or absence of a quorum for the transaction of
business but will not be counted for purposes of determining the number of votes
cast with respect to the particular proposal on which the broker has expressly
not voted. Broker non-votes with respect to proposals set forth in this Joint
Proxy Statement/Prospectus, other than with respect to the approval of the
amendment to the World Access Certificate, will therefore not be considered
votes cast and, accordingly, will not affect the determination as to whether a
majority of votes cast has been obtained with respect to a particular matter.
Because approval of the amendment to the World Access Certificate will require
the affirmative vote of a majority of the outstanding shares of World Access
Common Stock, broker non-votes with respect to such proposal will have the same
effect as a negative vote.
 
     BECAUSE APPROVAL OF THE AMENDMENT TO THE WORLD ACCESS CERTIFICATE, WHICH
APPROVAL IS INTENDED TO SATISFY ONE OF THE CONDITIONS TO THE MERGER, REQUIRES
THE AFFIRMATIVE VOTE OF THE HOLDERS OF A MAJORITY OF THE OUTSTANDING SHARES OF
WORLD ACCESS COMMON STOCK, ABSTENTIONS AND BROKER NON-VOTES WILL HAVE THE SAME
EFFECTS AS NEGATIVE VOTES. ACCORDINGLY, THE BOARD OF DIRECTORS OF WORLD ACCESS
URGES THE HOLDERS OF WORLD ACCESS COMMON STOCK TO COMPLETE, SIGN AND DATE THE
ACCOMPANYING PROXY AND RETURN IT PROMPTLY IN THE ENCLOSED, POSTAGE-PAID
ENVELOPE.
 
     Security Ownership by Certain Beneficial Owners and Management.  As of the
close of business on the World Access Record Date, directors and executive
officers of World Access and their respective affiliates may be deemed to be the
beneficial owners of shares of World Access Common Stock representing
approximately 5.8% of the outstanding voting power of World Access. Each of the
directors and executive officers of World Access has indicated that such person
intends to vote or direct the vote of all the shares of World Access Common
Stock over which such person has voting control in favor of the approval and
adoption of the Merger Agreement and the transactions contemplated thereby,
including the Merger and the Share Issuance, and in favor of all other proposals
described herein.
 
THE TELCO SYSTEMS SPECIAL MEETING
 
     General.  This Joint Proxy Statement/Prospectus is also being furnished to
stockholders of Telco Systems in connection with the solicitation of proxies by
the board of directors of Telco Systems for use at the Telco Systems Special
Meeting to be held at the principal offices of Telco Systems located at 63
Nahatan Street, Norwood, Massachusetts 02062, on November 30, 1998, at 10:00
a.m., local time, and at any adjournments or postponements thereof, for the
purposes set forth herein and in the accompanying notice of special meeting of
stockholders of Telco Systems.
 
     Matters to Be Considered.  At the Telco Systems Special Meeting,
stockholders of record of Telco Systems as of the close of business on the Telco
Systems Record Date will be asked to consider and vote upon proposals: (i) to
approve and adopt the Merger Agreement and the consummation of the transactions
contemplated thereby, including the Merger; and (ii) to transact such other
business as may properly come before the Telco Systems Special Meeting or any
adjournments or postponements thereof.
 
     Board of Directors' Recommendation.  THE BOARD OF DIRECTORS OF TELCO
SYSTEMS HAS DETERMINED THAT THE MERGER IS FAIR TO, AND IN THE BEST INTERESTS OF,
THE STOCKHOLDERS OF TELCO SYSTEMS AND HAS THEREFORE UNANIMOUSLY APPROVED AND
ADOPTED THE MERGER AGREEMENT AND THE CONSUMMATION OF THE TRANSACTIONS
CONTEMPLATED THEREBY, INCLUDING THE MERGER, AND UNANIMOUSLY RECOMMENDS THAT THE
STOCKHOLDERS OF TELCO SYSTEMS VOTE FOR THE APPROVAL AND ADOPTION OF THE MERGER
AGREEMENT AND THE CONSUMMATION OF THE TRANSACTIONS CONTEMPLATED THEREBY,
INCLUDING THE MERGER.
 
     Telco Systems Record Date.  The board of directors of Telco Systems has
fixed November 6, 1998 as the record date for determination of holders of Telco
Systems Common Stock entitled to notice of and to vote at the Telco Systems
Special Meeting. As of the close of business on the Telco Systems Record Date,
11,942,598 shares of Telco Systems Common Stock were outstanding, held by
approximately 379 holders of record. Only holders of record of Telco Systems
Common Stock as of the close of business on the Telco

Systems Record Date are entitled to notice of and to vote at the Telco Systems
Special Meeting and any adjournments or postponements thereof.
 
     Voting; Vote Required.  Each holder of record of Telco Systems Common Stock
on the Telco Systems Record Date is entitled to cast one vote for each share of
Telco Systems Common Stock held thereby, on the Telco Systems Record Date,
exercisable in person or by properly executed proxy, on each matter properly
submitted for the vote of the stockholders of Telco Systems at the Telco Systems
Special Meeting. A majority of the shares of Telco Systems Common Stock entitled
to vote at the Telco Systems Special Meeting will constitute a quorum for the
transaction of business at the Telco Systems Special Meeting.
 
     The approval of the Merger Agreement and the Merger will require the
affirmative vote of a majority of the outstanding shares of Telco Systems Common
Stock at the Telco Systems Special Meeting.
 
     Shares of Telco Systems Common Stock that are voted "FOR," "AGAINST" or
"WITHHELD" at the Telco Systems Special Meeting will be treated as being present
at such meeting for purposes of establishing a quorum and will also be treated
as votes eligible to be cast by the Telco Systems Common Stock present in person
or represented by proxy at the Telco Systems Special Meeting and entitled to
vote on the subject matter. Abstentions will be counted for purposes of
determining both the presence or absence of a quorum for the transaction of
business and the total number of votes cast with respect to a particular matter.
Broker non-votes will be counted for purposes of determining the presence or
absence of a quorum for the transaction of business but will not be counted for
purposes of determining the number of votes cast with respect to the particular
proposal on which the broker has expressly not voted. Abstention and broker
non-votes will have the same effect as a vote against the approval of the Merger
Agreement and the Merger, which approval will require the affirmative vote of a
majority of the outstanding shares of Telco Systems Common Stock.
 
     BECAUSE APPROVAL OF THE MERGER AGREEMENT REQUIRES THE AFFIRMATIVE VOTE OF
THE HOLDERS OF A MAJORITY OF THE OUTSTANDING SHARES OF TELCO SYSTEMS COMMON
STOCK, ABSTENTIONS AND BROKER NON-VOTES WILL HAVE THE SAME EFFECT AS NEGATIVE
VOTES. ACCORDINGLY, THE BOARD OF DIRECTORS OF TELCO SYSTEMS URGES THE HOLDERS OF
TELCO SYSTEMS COMMON STOCK TO COMPLETE, SIGN AND DATE THE ACCOMPANYING PROXY AND
RETURN IT PROMPTLY IN THE ENCLOSED, POSTAGE-PAID ENVELOPE.
 
     Security Ownership by Certain Beneficial Owners and Management.  As of the
close of business on the Telco Systems Record Date, directors and executive
officers of Telco Systems and their respective affiliates may be deemed to be
the beneficial owners of shares of Telco Systems Common Stock representing less
than 1% of the outstanding voting power of Telco Systems. Each of the directors
and executive officers of Telco Systems has indicated that such person intends
to vote or direct the vote of all the shares of Telco Systems Common Stock over
which such person has voting control in favor of the Merger Agreement and the
Merger. In addition, the owners of approximately 8% of the outstanding Telco
Systems Common Stock have entered into a Stockholders Proxy Agreement pursuant
to which each Stockholder has granted to World Access the right to vote all
voting securities of Telco Systems held by such Stockholder in favor of the
Merger Agreement and the Merger. See "The Stockholders Proxy Agreement."

Meeting and the Telco Systems Special Meeting, respectively. All shares of World
Access Common Stock and all shares of Telco Systems Common Stock that are

time or place (including, without limitation, for the purpose of soliciting
additional proxies), the persons named in the enclosed forms of proxy and voting
thereunder will have discretion to vote on such matters in accordance with their
best judgment; provided, however, that proxies voting against the proposals
presented in this Joint Proxy Statement/Prospectus may not be voted for

                                   THE MERGER
 
GENERAL
 
     The Merger Agreement provides that Telco Systems will be merged with and
into Merger Sub. As a result of the Merger, the separate corporate existence of
Telco Systems will cease and Merger Sub will continue as the surviving
corporation of the Merger and a direct wholly owned subsidiary of World Access.
The Merger will take place as promptly as practicable after the adoption and
approval of the Merger Agreement and the transactions contemplated thereby, by
the stockholders of World Access and Telco Systems and the satisfaction or
waiver of the other conditions to the Merger set forth in the Merger Agreement.
See "The Merger Agreement."
 
CONVERSION OF TELCO SYSTEMS COMMON STOCK
 
     At the Effective Time, by virtue of the Merger and without any action on
the part of World Access, Old World Access, Merger Sub, Telco Systems or the
holders of Telco Systems Common Stock, each share of Telco Systems Common Stock
issued and outstanding immediately prior to the Effective Time (other than any
shares of Telco Systems Common Stock to be cancelled as described below and
shares held by persons who have perfected their appraisal rights (if applicable)
under Section 262 of the DGCL) together with the Associated Rights will
forthwith cease to exist and will be converted into and become exchangeable for
the Merger Consideration described below.
 
     Telco Systems Common Stock.  Pursuant to the Merger Agreement, each
outstanding share of Telco Systems Common Stock (together with the Associated
Rights) (other than any shares of Telco Systems to be cancelled as described
below and shares held by persons who have perfected their appraisal rights (if
applicable) under Section 262 of the DGCL) will be converted into that number of
shares of World Access Common Stock equal to the quotient of $17.00 divided by
the average of the last reported sales prices of one share of World Access
Common Stock on Nasdaq during the period of the 20 most recent trading days
ending three business days before the Effective Time (the "World Access Market
Price") (unless the World Access Market Price exceeds $36.00 per share, in which
case each outstanding share of Telco Systems Common Stock will be converted into
 .4722 shares of World Access Common Stock, or unless the World Access Market
Price is less than $29.00 per share, in which case each outstanding share of
Telco Systems Common Stock will be converted into .5862 shares of World Access
Common Stock), provided that (i) the nominal value of the consideration to be
received by holders of Telco Systems Common Stock is no less than the Minimum
Nominal Value and (ii) World Access may elect to pay cash in lieu of shares of
World Access Common Stock so long as such cash does not constitute more than 55%
of the Merger Consideration (based on the average of the high and low trading
prices of the World Access Common Stock on the day the Merger is consummated).
If World Access elects to pay cash in the Merger in lieu of issuing additional
shares of World Access Common Stock, then each share of Telco Systems Common
Stock will be exchanged for a pro rata portion of (i) the Aggregate Cash Pool
(which is subject to the 55% limitation described above) and (ii) the aggregate
number of shares of World Access Common Stock to be issued in the Merger, which
will be equal to the number of shares of World Access Common Stock that would
have been issued in the Merger had World Access not elected to include cash in
the Merger Consideration less that number of such shares having a value (based
upon the World Access Market Price) equal to the Aggregate Cash Pool. World
Access will determine and publicly announce what portion (if any) of the Merger
Consideration it will pay in cash on the third business day prior to the
Effective Time.
 
     Telco Systems Treasury Stock.  Each share of Telco Systems Common Stock
held in the treasury of Telco Systems and each share of Telco Systems Common
Stock owned by World Access together with any Associated Rights, immediately
prior to the Effective Time will be cancelled and extinguished without any
conversion thereof, and no payment will be made with respect thereto.
 
     No Fractional Shares.  No fractional share certificates for World Access
Common Stock will be issued upon the surrender for exchange of certificates
evidencing shares of Telco Systems Common Stock. In lieu
 
                                       37
<PAGE>   49
 
thereof, the Exchange Agent or World Access, as the case may be, will pay each
holder of Telco Systems Common Stock an amount in cash calculated as provided in
the Merger Agreement.
 
     Options.  At the Effective Time, each option granted by Telco Systems to
purchase shares of Telco Systems Common Stock (other than options granted to new
employees subsequent to June 4, 1998) that is outstanding and unexercised
immediately prior to the Effective Time will immediately vest in full upon the
consummation of the Merger and will be assumed by World Access and converted
into an option to purchase shares of World Access Common Stock in such number
and at such exercise price as follows and will otherwise have the same terms and
conditions as in effect immediately prior to the Effective Time: (i) the number
of shares of World Access Common Stock to be subject to the new option will be
equal to the product of (A) the number of shares of Telco Systems Common Stock
subject to the original option and (B) the Exchange Ratio (unless the Exchange
Ratio is adjusted to ensure that holders of Telco Systems Common Stock receive
the Minimum Nominal Value in the Merger, in which event the Exchange Ratio for
purposes of this determination will be equal to $12.00 divided by the World
Access Market Price); (ii) the exercise price per share of World Access Common
Stock under the new option will be equal to the quotient of (A) the exercise
price per share of Telco Systems Common Stock under the original option divided
by (B) the Exchange Ratio (unless the Exchange Ratio is adjusted to ensure that
holders of Telco Systems Common Stock receive the Minimum Nominal Value in the
Merger, in which event the Exchange Ratio for purposes of this determination
will be equal to $12.00 divided by the World Access Market Price); and (iii)
upon each exercise of options by a holder thereof, the aggregate number of
shares of World Access Common Stock deliverable upon such exercise shall be
rounded, if necessary, to the nearest whole share and the aggregate exercise
price shall be rounded up, if necessary, to the nearest cent. Under the Merger
Agreement, World Access has agreed to file a registration statement on Form S-8
with respect to the shares of World Access Common Stock subject to the Telco
Systems 1980 Stock Option Plan, the Telco Systems 1988 Non-Statutory Stock
Option Plan and the Telco Systems 1990 Stock Option Plan (collectively, the
"Telco Systems Option Plans") following the Effective Time in order for such
shares of World Access Common Stock to be sold without restriction.
 
     Certain Adjustments.  If, between the date of the Merger Agreement and the
Effective Time, the outstanding shares of Telco Systems Common Stock or World
Access Common Stock are changed into a different number of shares by reason of
any reclassification, recapitalization, split-up, combination or exchange of
shares, or any dividend payable in stock or other securities is declared thereon
with a record date within such period then the Exchange Ratio will be adjusted
accordingly to provide the holder of Telco Systems Common Stock the same
economic effect as contemplated by the Merger Agreement prior to such
reclassification, recapitalization, split-up, combination, exchange or dividend.
 
BACKGROUND OF THE MERGER
 
     In April 1997, Dr. William Smith, Chief Executive Officer of Telco Systems,
Mr. Steven Odom, Chairman and Chief Executive Officer of World Access, Mr.
William Stuart, Chief Financial Officer of Telco Systems, and Mr. Hensley West,
President and Chief Operating Officer of World Access, held brief preliminary
discussions regarding the possibility of a business combination between World
Access and Telco Systems. These preliminary discussions focused on the
complementary strengths of the businesses of the two companies, developing
trends in the telecommunications industry and the acquisition strategy of World
Access. At a subsequent meeting in April 1997, senior management from both
companies discussed a potential distribution relationship between the two
companies as an alternative to a business combination. These discussions
terminated before World Access and Telco Systems exchanged any non-public
information or developed any specific plans with respect to a transaction.
 
     In September 1997, the board of directors of Telco Systems authorized
Broadview, the financial advisor of Telco Systems, to approach certain companies
regarding their interest in exploring a business combination transaction with
Telco Systems. None of these contacts resulted in mutually acceptable
transaction proposals.
 
     At an industry conference in late October 1997, Dr. Smith, Mr. Odom, Mr.
Stuart and Mr. West reviewed their earlier discussions concerning a business
combination of Telco Systems and World Access. In
 
                                       38
<PAGE>   50
 
anticipation of further discussions regarding a possible business combination,
on November 7, 1997, the companies entered into a confidentiality agreement (the
"Confidentiality Agreement"), pursuant to which they agreed to exchange
non-public information. Following execution of the Confidentiality Agreement,
representatives of World Access and Telco Systems discussed and provided each
other with certain business, financial, legal, tax and accounting information
relating to World Access and Telco Systems. By late November 1997, the companies
had terminated these discussions believing that the time and circumstances were
not appropriate to effect the contemplated business combination.
 
     In April 1998, Mr. Odom contacted Dr. Smith and suggested that they
recommence the earlier discussions of a business combination of World Access and
Telco Systems. On April 28 and 29, 1998, Dr. Smith and Mr. Stuart met with Mr.
Odom, Mr. West and Mr. Michael Mies, Vice President and Treasurer of World
Access, to discuss a possible combination of the companies. Following these
meetings and continuing through June 4, 1998, the senior management, legal
counsel, independent accountants and financial advisors of each of World Access
and Telco Systems conducted a due diligence review and continued discussions
with respect to the other company.
 
     At a meeting of the Telco Systems board of directors held on May 18, 1998,
senior management of Telco Systems and representatives of Broadview discussed
the businesses of World Access, the rationale for the proposed merger and the
proposed principal terms and conditions of the transaction. The management of
Telco Systems also advised the Telco Systems board of directors that the
companies were reviewing the accounting treatment of the proposed transaction to
determine if pooling of interests accounting would be appropriate. Telco
Systems' legal counsel reviewed certain legal matters with the Telco Systems
board of directors, including the fiduciary duties of the Telco Systems
directors, and certain aspects of the transaction process. At this meeting,
Messrs. Odom, West and Mies addressed the Telco Systems board of directors
concerning World Access and its businesses and their view of the proposed
transaction. The Telco Systems board of directors directed management of Telco
Systems, with the assistance of Telco Systems' legal counsel and financial
advisors, to continue to pursue the proposed transaction. The management of
Telco Systems then continued to meet with Messrs. Odom, West and Mies, during
which they agreed upon the basic structure of the proposed merger and discussed
an exchange ratio based on a nominal value of $18 per share, provided that the
merger could be accounted for as a pooling of interests.
 
     On May 21, 1998, World Access provided Telco Systems with a draft merger
agreement and related stockholders proxy agreement. Commencing on May 26, 1998,
representatives of Telco Systems and World Access began negotiating the terms of
the draft transaction agreements and continued to discuss various issues
relating to the proposed transaction, including possible difficulties in
qualifying for pooling of interest accounting treatment.
 
     At a meeting of the Telco Systems board of directors held on June 1, 1998,
the Telco Systems management updated the Telco Systems board of directors on the
status of the due diligence review of, and the negotiations with, World Access
and discussed the then-proposed terms of the merger, which were conditioned upon
the ability to utilize pooling of interests accounting for the merger and which
would have established the merger exchange ratio based upon a nominal value of
$18 per share of Telco Systems Common Stock (instead of the $17 per share
nominal value of the Exchange Ratio as of June 4, 1998) but otherwise subject to
the same methodology as the Exchange Ratio. At the meeting, Broadview reviewed
the financial terms of the then-proposed merger, and discussed the results of
its review of the businesses of Telco Systems and World Access and certain other
matters. Telco Systems' legal counsel reviewed the status of its due diligence
review of World Access and the terms and conditions of the proposed merger
agreement and the proposed stockholders proxy agreement and reviewed relevant
aspects of applicable law. After extensive discussion regarding the terms of the
proposed merger, the unresolved issues relating to World Access' ability to
account for the merger utilizing pooling of interests accounting and the related
uncertainty that such issues presented to the proposed transaction, the Telco
Systems board of directors authorized management, with the assistance of Telco
Systems' legal counsel and financial advisors, to continue to pursue the
proposed merger and to explore the financial terms of a proposed merger with
World Access that would be accounted for utilizing the purchase method of
accounting instead of the pooling of interests method.
 
                                       39
<PAGE>   51
 
     On June 2, 1998, following further discussion among representatives of
World Access and Telco Systems, including representatives of their respective
independent accountants, and in light of continuing issues relating to World
Access' ability to account for the proposed merger utilizing pooling of
interests accounting, the companies' respective managements determined to
recommend to their board of directors that the proposed merger be accounted for
utilizing the purchase method of accounting and that the merger exchange ratio
be based upon a nominal value of $17 per share of Telco Systems Common Stock (as
of June 4, 1998) rather than the $18 per share nominal value which was discussed
in the context of a proposed merger that could be accounted for as a pooling of
interests. The other principal terms of the proposed merger would remain
unchanged.
 
     Mr. Odom personally advised each of the directors of World Access
concerning the status of the negotiations with the management of Telco Systems
with respect to the proposed merger on a periodic basis from late April 1998 to
June 2, 1998.
 
     At a June 2, 1998 meeting of the World Access board of directors, World
Access management updated the directors on the terms of the proposed merger and
the results of the financial and operational due diligence of Telco Systems that
had been undertaken by World Access management, and Robinson-Humphrey presented
its review and analysis of the terms of the proposed merger. After extensive
discussion regarding the terms of the proposed merger and the presentations of
management and Robinson-Humphrey, the World Access board of directors
unanimously approved the Merger and the issuance of the World Access Common
Stock upon the terms and conditions set forth in the draft of the Merger
Agreement furnished to it and authorized management to complete the negotiation
of the Merger Agreement, provided that the exchange ratio be based on a nominal
value of no more than $18 per share in the context of a merger that could be
accounted for as a pooling of interests and that World Access receive the
fairness opinion from Robinson-Humphrey.
 
     At a telephonic meeting of the Telco Systems board of directors on June 2,
1998, Telco Systems' management updated the directors on the proposed revisions
to the financial terms of the proposed merger. After extensive discussion
regarding the revised proposal and the recent trading prices of the World Access
Common Stock, the Telco Systems board of directors authorized management to
continue to pursue the proposed transaction and requested that management seek
to modify the manner in which the lower and upper ranges of the exchange ratio
would be determined.
 
     At a telephonic meeting of the Telco Systems board of directors on June 4,
1998, Telco Systems' management updated the Telco Systems board of directors on
the proposed upper and lower ranges of the proposed Exchange Ratio and World
Access' request that certain senior management agree to defer their right to
certain change of control payments resulting from the consummation of the
Merger. Broadview updated its financial review of the proposed merger based upon
the revised financial terms of the transaction. Telco Systems' legal counsel
then reviewed the remaining unresolved items. After lengthy discussion, the
Telco Systems board of directors unanimously (with one director absent at the
time of the vote) determined that the Merger, upon the terms and conditions set
forth in the Merger Agreement, is fair to and in the best interests of Telco
Systems and its stockholders, adopted the Merger Agreement and recommended that
Telco Systems stockholders vote in favor of approving and adopting the Merger
Agreement and the consummation of the transactions contemplated thereby,
including the Merger.
 
     Also on June 4, 1998, following completion of final negotiations on the
Merger Agreement and agreement by certain of Telco Systems' senior management to
the requested deferral of their change of control payments, the Merger Agreement
and the Stockholders Proxy Agreement were executed and the companies publicly
announced the transaction.
 
     On October 9, 1998, Telco Systems management and representatives of
Broadview met with World Access management and representatives of
Robinson-Humphrey and informed them that given the significant decline in the
trading price of the World Access Common Stock and its effect on the value of
the consideration to be received by the Telco Systems stockholders in the
Merger, Telco Systems believed that it would be difficult for its board of
directors to recommend that the Telco Systems stockholders vote in favor of the
Merger Agreement and that an increase in such value was appropriate. In that
regard, World Access
                                       40
<PAGE>   52
 
believed that it was necessary to revise the terms of the proposed merger to
make more likely its consummation. Thereafter, management of Telco Systems and
World Access negotiated the terms of the First Amendment which provides for,
among other things, the Minimum Nominal Value. On October 13, 1998, World Access
and Telco Systems agreed in principle to terms of the First Amendment and issued
a joint press release to such effect.
 
     On October 16, 1998, World Access management advised the boards of
directors of World Access and Old World Access of the proposed revised terms of
the Merger, and Robinson-Humphrey delivered its opinion dated October 16, 1998
with respect thereto.
 
     A telephonic meeting of the boards of directors of World Access and Old
World Access was held on October 27, 1998. At that meeting, World Access
management and legal advisors updated the boards of directors regarding the
status of the Merger and the revised terms thereof that had been negotiated.
Robinson-Humphrey delivered written confirmation of its October 16, 1998 opinion
to the effect that the consideration to be paid in the Merger as proposed to be
amended was fair from a financial point of view to World Access and Old World
Access. After extensive discussion, the boards of directors of World Access and
Old World Access unanimously approved the First Amendment and directed
management to proceed with the Merger as proposed to be amended.
 
     A telephonic meeting of the board of directors of Telco Systems was held on
October 26, 1998. At that meeting, Telco Systems management and legal advisors
updated the board of directors regarding the status of the Merger and the
revised terms thereof that had been negotiated. Broadview delivered its opinion
that the consideration to be received by Telco Systems stockholders in the
Merger as proposed to be amended was fair, from a financial point of view, to
such stockholders. After extensive discussions, the board of directors of Telco
Systems unanimously approved the First Amendment and directed management to
proceed with the Merger as it was proposed to be amended.
 
     On October 27, 1998, the First Amendment was executed, and on October 28,
1998 the companies publicly announced such event.
 
WORLD ACCESS REASONS FOR THE MERGER; RECOMMENDATION OF THE WORLD ACCESS BOARD OF
DIRECTORS
 
     The board of directors of World Access has carefully considered the
advisability of the Merger and believes that the terms of the Merger Agreement
are fair to, and that the Merger is in the best interests of, World Access and
its stockholders. THE BOARD OF DIRECTORS OF WORLD ACCESS HAS UNANIMOUSLY
APPROVED AND ADOPTED THE MERGER AGREEMENT AND THE CONSUMMATION OF THE
TRANSACTIONS CONTEMPLATED THEREBY, INCLUDING THE MERGER AND THE SHARE ISSUANCE,
AND UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS OF WORLD ACCESS VOTE FOR THE
APPROVAL AND ADOPTION OF THE MERGER AGREEMENT AND THE CONSUMMATION OF THE
TRANSACTIONS CONTEMPLATED THEREBY, INCLUDING THE MERGER AND THE SHARE ISSUANCE.
 
     In the course of its deliberations, the board of directors of World Access
reviewed, and consulted with the World Access management and financial and legal
advisors concerning, a number of factors relevant to the Merger. In particular,
the board of directors of World Access considered, among other things:
 
          (i) the written opinion of Robinson-Humphrey, dated June 4, 1998,
     which was updated on October 16, 1998 and confirmed in writing on October
     27, 1998, that the consideration to be paid by World Access in the Merger
     is fair, from a financial point of view, to World Access;
 
          (ii) the business, operations and prospects of Telco Systems;
 
          (iii) the combined company's more complete portfolio of
     telecommunications products, including Telco Systems' bandwidth
     optimization products which have not previously been offered by World
     Access;
 
          (iv) the opportunities for economies of scale and operating
     efficiencies that may result from the Merger, particularly in terms of the
     integration of office facilities, information systems and support
     functions;
 
                                       41
<PAGE>   53
 
          (v) based on the relative earnings of both companies and the Exchange
     Ratio, the expected accretion to the current stockholders of World Access
     assuming certain potential synergies are achieved;
 
          (vi) the terms and conditions of the Merger Agreement, including that
     the Merger will be a tax-free reorganization for federal income tax
     purposes, that World Access may terminate the Merger Agreement if the World
     Access Market Price is less than $12.00 per share and that World Access may
     elect to use cash for a portion of the Merger Consideration;
 
          (vii) the conclusion of a review of the financial terms of certain
     recent business combinations which were deemed comparable, in whole or in
     part, to the proposed Merger;
 
          (viii) the historical market prices of, and their information with
     respect to, the World Access Common Stock;
 
          (ix) the prospects for the long-term performance of World Access
     Common Stock as well as the potential volatility of such stock;
 
          (x) the ability of the Merger to better position World Access to deal
     with uncertainties which may face the telecommunications industry; and
 
          (xi) the belief of the World Access board of directors that the Merger
     will enhance the combined company's product research and development
     activities due, in part, to the technical expertise of Telco Systems.
 
     The board of directors of World Access also considered a variety of
inherent risks and other potentially negative factors in its deliberations
concerning the Merger. In particular, the board of directors of World Access
considered, among other things: (i) the potential dilutive effect of the
issuance of World Access Common Stock pursuant to the Merger; (ii) the risk that
public market price of the World Access Common Stock might be adversely affected
by announcement of the Merger; (iii) the effect of the Minimum Nominal Value to
be received by the holders of Telco Systems Common Stock; and (iv) other risks
described above under "Risk Factors."
 
     Based on the foregoing matters, and such other matters as the members of
the board of directors of World Access deemed relevant, the World Access board
of directors unanimously approved the Merger Agreement and the transactions
contemplated thereby.
 
     The foregoing discussion of the information and factors considered and
given weight by the board of directors of World Access is not intended to be
exhaustive but is believed to include all material factors considered by such
board of directors. In addition, in reaching the determination to approve and
recommend the Merger Agreement and the transactions contemplated thereby, the
board of directors of World Access did not assign any relative or specific
weights to the foregoing factors which were considered, and individual directors
may have given different weights to different factors. The board of directors of
World Access is, however, unanimous in its recommendation to the holders of
World Access Common Stock that the Merger Agreement and the transactions
contemplated thereby be approved.
 
TELCO SYSTEMS REASONS FOR THE MERGER; RECOMMENDATION OF THE TELCO SYSTEMS BOARD
OF DIRECTORS
 
     The board of directors of Telco Systems has carefully considered the
advisability of the Merger and believes that the terms of the Merger Agreement
are fair to, and that the Merger is in the best interests of, Telco Systems and
its stockholders. THE BOARD OF DIRECTORS OF TELCO SYSTEMS HAS UNANIMOUSLY
APPROVED AND ADOPTED THE MERGER AGREEMENT AND THE CONSUMMATION OF THE
TRANSACTIONS CONTEMPLATED THEREBY, INCLUDING THE MERGER, AND UNANIMOUSLY
RECOMMENDS THAT THE STOCKHOLDERS OF TELCO SYSTEMS VOTE FOR THE APPROVAL AND
ADOPTION OF THE MERGER AGREEMENT AND THE CONSUMMATION OF THE TRANSACTIONS
CONTEMPLATED THEREBY, INCLUDING THE MERGER.

     In the course of its deliberations, the board of directors of Telco Systems
reviewed, and consulted with Telco Systems' management and financial and legal
advisors concerning, a number of factors relevant to the Merger. In particular,
the board of directors of Telco Systems considered, among other things:
 
          (i) The Telco Systems board of directors' familiarity with, and review
     of, Telco Systems' business, operations, financial condition, earnings and
     prospects and that, on a combined basis with World Access, the companies
     will likely have greater financial stability and strength due to the
     inherent increase in scale economies and the market diversification
     resulting from the combination of divergent businesses.
 
          (ii) The Telco Systems board of directors' review, based in part on
     presentations by Broadview, Telco Systems' financial advisor, of (a) the
     business, operations, financial condition and earnings of World Access on a
     historical and prospective basis and of the combined company on a pro forma
     basis, and (b) the historical market price of the World Access Common Stock
     and the resulting relative interests of Telco Systems stockholders and
     World Access stockholders in the equity of the combined company.
 
          (iii) The presentations of Broadview to the Telco Systems board of
     directors on June 1, 1998, June 4, 1998, October 22, 1998 and October 26,
     1998 in connection with the Telco Systems board of directors' consideration
     of the Merger Agreement, and the opinion dated October 26, 1998 of
     Broadview that, as of such date, the Merger Consideration (after giving
     effect to the First Amendment) was fair from a financial point of view to
     the Telco Systems stockholders. See "-- Opinion of Telco Systems' Financial
     Advisor."
 
          (iv) The fact that (a) pursuant to the First Amendment, the nominal
     value of the Telco Systems Common Stock used to calculate the Exchange
     Ratio would not be less than $12.00 per share, which represented a premium
     of 88.2% over the closing price of the Telco Systems Common Stock on Nasdaq
     on October 12, 1998 (the last trading day prior to announcement of the
     companies' agreement in principle regarding the Minimum Nominal Value), (b)
     if the World Access Market Price was greater than $20.47, the Telco Systems
     stockholders would receive an incremental increase in value until the World
     Access Market Price reached $29.00, (c) if the World Access Market Price
     was between $29.00 and $36.00, the nominal value of the Telco Systems
     Common Stock to be used to calculate the Exchange Ratio would be $17.00 per
     share, and (d) the $17.00 nominal value could be increased if the World
     Access Market Price exceeded $36.00 per share.
 
          (v) In response to the significant price decline in the World Access
     Common Stock since the initial execution of the Merger Agreement, the fact
     that the First Amendment to the Merger Agreement ensures that the Telco
     Systems stockholders would receive a minimum nominal value of $12.00 for
     each share of Telco Systems Common Stock.
 
          (vi) The liquidity of the World Access Common Stock to be received by
     the Telco Systems stockholders, which is required to be quoted on Nasdaq as
     a condition to the consummation of the Merger.
 
          (vii) The provisions of the Merger Agreement that permit Telco Systems
     to consider alternative bona fide third-party offers to acquire Telco
     Systems and permit Telco Systems to provide information to and negotiate
     with such parties and to terminate the Merger Agreement, subject to the
     payment of significant fees and expenses to World Access, if prior to the
     Effective Time the Telco Systems board of directors terminates the Merger
     Agreement or withdraws or modifies in a manner adverse to World Access its
     recommendation of the Merger pursuant to the exercise by the Telco Systems
     board of directors of its fiduciary duties to stockholders. See "The Merger
     Agreement -- No Solicitation of Transactions", "-- Termination" and
     "-- Termination Fees and Expenses".
 
          (viii) The opportunity for Telco Systems stockholders to participate,
     as holders of World Access Common Stock, in a larger company of which
     former Telco Systems stockholders would hold approximately 15.9% of the
     equity (after giving effect to the Resurgens Transaction) (or 7.9% if 55%
     of the Merger Consideration is paid in cash), and to do so by means of a
     transaction which is designed to be tax-free to Telco Systems'
     stockholders.
                                       43
<PAGE>   55
 
          (ix) The interests that the Telco Systems management and the Telco
     Systems board of directors may be deemed to have in the Merger that are in
     addition to their interests as stockholders of Telco Systems generally. See
     "-- Interests of Certain Persons in the Merger".
 
          (x) Possible difficulties involved in integrating the two companies'
     managements, corporate cultures and businesses.
 
          (xi) Possible difficulties that the combined company may have in
     effectively marketing its broader array of products to the combined
     company's customer base.
 
          (xii) The risks discussed above under "Risk Factors."
 
     The foregoing discussion of the information and factors considered and
given weight by the board of directors of Telco Systems is not intended to be
exhaustive but is believed to include all material factors considered by the
board of directors of Telco Systems. The board of directors of Telco Systems
made no determination as to the future value of the World Access Common Stock in
reaching its determination that the Merger is fair to and in the best interests
of Telco Systems and its stockholders. In reaching the determination to approve
and recommend the Merger Agreement and the transactions contemplated thereby,
the board of directors of Telco Systems did not assign any relative or specific
weights to the foregoing factors which were considered. In addition, individual
members of the Telco Systems board of directors may have given different weight
to different factors.
 
OPINION OF WORLD ACCESS' FINANCIAL ADVISOR
 
     Pursuant to an engagement letter dated May 21, 1998, World Access retained
Robinson-Humphrey to deliver a fairness opinion in connection with the proposed
Merger.
 
     At the June 2, 1998 meeting of the World Access board of directors,
Robinson-Humphrey delivered its oral opinion and written analysis and
subsequently on June 4, 1998 delivered its updated written analysis and written
opinion that, based upon and subject to various considerations set forth in such
opinion, as of June 4, 1998, the Exchange Ratio was fair to World Access and Old
World Access from a financial point of view. On October 16, 1998,
Robinson-Humphrey delivered its written opinion that, based upon and subject to
various considerations set forth in such opinion, as of October 16, 1998, the
consideration to be paid by World Access in the proposed Merger pursuant to the
proposed terms of the First Amendment was fair to World Access and Old World
Access from a financial point of view. On October 27, 1998, Robinson-Humphrey
delivered its written confirmation of its October 16, 1998 opinion. No
limitations were imposed by the World Access board of directors upon
Robinson-Humphrey with respect to the investigations made or the procedures

Robinson-Humphrey's opinion refer to Robinson-Humphrey's written opinion dated

     THE FULL TEXT OF THE OPINION OF ROBINSON-HUMPHREY, WHICH SETS FORTH THE
ASSUMPTIONS MADE, MATTERS CONSIDERED AND LIMITS ON THE REVIEW UNDERTAKEN IN
CONNECTION WITH THE OPINION, IS ATTACHED HERETO AS APPENDIX B TO THIS JOINT
PROXY STATEMENT/PROSPECTUS AND IS INCORPORATED HEREIN BY REFERENCE. WORLD ACCESS
STOCKHOLDERS ARE URGED TO READ SUCH OPINION CAREFULLY IN ITS ENTIRETY.
ROBINSON-HUMPHREY'S OPINION IS ADDRESSED TO THE BOARD OF DIRECTORS OF WORLD
ACCESS, IS DIRECTED ONLY TO THE CONSIDERATION TO BE PAID IN THE MERGER AND DOES
NOT CONSTITUTE A RECOMMENDATION TO ANY STOCKHOLDER OF WORLD ACCESS AS TO HOW
SUCH STOCKHOLDER SHOULD VOTE AT THE WORLD ACCESS SPECIAL MEETING. THE SUMMARY OF
THE OPINION OF ROBINSON-HUMPHREY SET FORTH IN THIS JOINT PROXY
STATEMENT/PROSPECTUS IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT
OF SUCH OPINION.
 
     In arriving at its opinion, Robinson-Humphrey reviewed and analyzed (1) the
Merger Agreement and the proposed First Amendment thereto, (2) publicly
available information concerning World Access and Telco Systems, which
Robinson-Humphrey believed to be relevant to its inquiry, (3) financial and
operating information with respect to the businesses, operations and prospects
of World Access and Telco Systems furnished to Robinson-Humphrey by World Access
or Telco Systems, (4) trading histories of World Access Common Stock and Telco
Systems Common Stock and a comparison of those trading histories with those of
other companies which Robinson-Humphrey deemed relevant, (5) a comparison of the
historical financial
                                       44
<PAGE>   56
 
results and present financial condition of each of World Access and Telco
Systems with those of other companies which Robinson-Humphrey deemed relevant,
(6) a comparison of the financial terms of the Merger with the financial terms
of certain other recent transactions which Robinson-Humphrey deemed relevant,
(7) certain potential pro forma effects of the Merger on World Access and (8)
certain historical data relating to percentage premiums paid in acquisitions of
publicly traded companies. In addition, Robinson-Humphrey held discussions with
the managements of World Access and Telco Systems concerning their respective
businesses, operations, assets, present conditions and future prospects and
undertook such other studies, analyses and investigations as Robinson-Humphrey
deemed appropriate.
 
     Robinson-Humphrey relied upon the accuracy and completeness of the
financial and other information used by Robinson-Humphrey in arriving at
Robinson-Humphrey's opinion without independent verification. With respect to
the financial forecasts/projections of World Access and Telco Systems and
synergies anticipated from the Merger, Robinson-Humphrey assumed that such
information had been reasonably prepared on bases reflecting the best currently
available estimates and judgments of the managements of World Access and Telco
Systems as to the future financial performance of World Access and Telco Systems
and synergies anticipated from the Merger. In arriving at such opinion,
Robinson-Humphrey conducted only a limited physical inspection of the properties
and facilities of World Access and Telco Systems, and Robinson-Humphrey did not
make or obtain any evaluations or appraisals of the assets or liabilities of
World Access or of Telco Systems.
 
     Robinson-Humphrey's opinion was necessarily based upon market, economic and
other conditions as they may have existed and could be evaluated as of October
16, 1998. The financial markets in general and the markets for the common stock
of World Access and of Telco Systems, in particular, are subject to volatility,
and Robinson-Humphrey's opinion did not purport to address potential
developments in the financial markets or the markets for the common stock of
World Access and of Telco Systems after the date thereof. The opinion did not
address the underlying business decision of World Access to effect the Merger.
Robinson-Humphrey assumed that the Merger would be consummated on the terms
described in the Merger Agreement, without any waiver of any material terms or
conditions by World Access or Telco Systems.
 
     In connection with the preparation of its fairness opinion,
Robinson-Humphrey performed certain financial and comparative analyses, the
material portions of which are summarized below. The summary set forth below
includes the financial analyses used by Robinson-Humphrey and deemed to be
material, but does not purport to be a complete description of the analyses
performed by Robinson-Humphrey in arriving at its opinion. The preparation of a
fairness opinion involves various determinations as to the most appropriate and
relevant methods of financial analysis and the application of those methods to
the particular circumstances, and therefore, such an opinion is not readily
susceptible to partial analysis or summary description. In addition,
Robinson-Humphrey believes that its analyses must be considered as an integrated
whole, and that selecting portions of such analyses and the factors considered
by it, without considering all of such analyses and factors, could create a
misleading or an incomplete view of the process underlying its analyses set
forth in the opinion. In performing its analyses, Robinson-Humphrey made
numerous assumptions with respect to industry performance, general business and
economic conditions and other matters, many of which are beyond the control of
World Access or Telco Systems. Any estimates contained in such analyses are not
necessarily indicative of actual past or future results or values, which may be
significantly more or less favorable than as set forth therein. Estimates of
values of companies do not purport to be appraisals or necessarily to reflect
the price at which such companies may actually be sold, and such estimates are
inherently subject to uncertainty. No public company utilized as a comparison is
identical to World Access or Telco Systems. An analysis of the results of such a
comparison is not mathematical; rather, it involves complex considerations and
judgments concerning differences in financial and operating characteristics of
the comparable companies and other factors that could affect the public trading
values of companies to which World Access and Telco Systems are being compared.
 
     The following is a summary of certain analyses performed by
Robinson-Humphrey in connection with rendering its opinion. Robinson-Humphrey
presented an oral opinion and the written analysis discussed below at a meeting
of the board of directors of World Access on June 2, 1998 and provided the
updated written analysis and written opinion on June 4, 1998. On October 16,
1998, Robinson-Humphrey provided the
                                       45
<PAGE>   57
 
updated written opinion. On October 27, 1998, Robinson-Humphrey delivered its
written confirmation of its October 16, 1998 opinion.
 
     Certain analyses performed by Robinson-Humphrey utilized financial
forecasts for World Access and Telco Systems. Such financial forecasts were
based upon estimates published by equity research analysts in the investment
community, including Robinson-Humphrey's research analyst.
 
     Historical Stock Price Analysis.  Robinson-Humphrey analyzed the prices at
which Telco Systems Common Stock has traded since January 1, 1993. In calendar
1993, the high price was $10.38, and the low price was $6.63. In calendar 1994,
the high price was $18.00, and the low price was $8.00. In calendar 1995, the
high price was $16.56, and the low price was $9.38. In calendar 1996, the high
price was $21.25, and the low price was $8.63. In calendar 1997, the high price
was $23.88, and the low price was $8.84. In calendar 1998, through June 4, 1998
(the last trading day prior to the initial announcement of the Merger), the high
price was $14.88, and the low price was $9.02. From June 4, 1998 through October
26, 1996, the high price was $15.63 and the low price was $3.69. Over the period
from January 1, 1997 through June 3, 1998, Robinson-Humphrey observed that 54.4%
of the outstanding shares of Telco Systems were traded in a price range of $9.00
to $12.00 per share, 15.7% of the outstanding shares were traded in a price
range of $12.00 to $15.00 per share, 22.4% were traded in a price range of
$15.00 to $18.00 per share, 4.9% were traded in a price range of $18.00 to
$21.00 per share and 2.5% were traded in a price range of $21.00 to $24.00 per
share. Over the period from June 3, 1998 through October 26, 1998,
Robinson-Humphrey observed that 3.4% of the outstanding shares of Telco Systems
were traded in a price range of $6.00 to $7.80 per share, 2.0% were traded in a
price range of $7.80 to $9.60 per share, 23.6% were traded in a price range of
$9.60 to $11.40 per share, 0.0% were traded in a price range of $11.40 to $13.20
per share and 71.0% were traded in a price range of $13.20 to $15.00 per share.
 
     Based on Telco Systems' closing stock price of $11.22 per share on June 4,
1998, and the Merger's implied equity value per share for Telco Systems of
$12.00, Robinson-Humphrey calculated per share premiums of 7.0%, 17.1% and 15.7%
to Telco Systems' closing stock prices at one trading day, one week and four
weeks prior to the initial announcement date, respectively.
 
     Comparable Public Company Analysis.  Robinson-Humphrey reviewed and
compared certain publicly available financial, operating and market valuation
data for selected public companies in the telecommunications equipment industry
to the corresponding financial and operating data for Telco Systems. Robinson-
Humphrey included the following companies in its comparable public company
analysis: ADC Telecommunications, Inc., Cisco Systems, Inc., Digital Link
Corporation, General DataComm Industries, Inc., Intelect Communications, Inc.,
Larscom Incorporated, Newbridge Networks Corporation, Network Equipment
Technologies, Inc., Premisys Communications, Reltec Corporation, Tellabs, Inc.,
Verilink Corporation and World Access. Robinson-Humphrey noted that none of the
comparable public companies was identical to Telco Systems and that,
accordingly, the analysis of comparable public companies necessarily involves
complex considerations and judgments concerning differences in financial and
operating characteristics of the companies reviewed and other factors that would
affect the market values of comparable companies. Robinson-Humphrey calculated
various financial ratios and multiples based upon the closing prices of the
common stock of the comparable companies as of October 26, 1998, the most recent
publicly available information for the various companies and information
concerning the projected financial results of the various companies, as
promulgated by equity research analysts of nationally recognized investment
banking firms. The following valuation ratios were used in determining ranges of
implied equity values per share of Telco Systems: (i) current market price to
latest twelve months ("LTM") earnings per share, current market price to
calendar 1998 and 1999 earnings per share estimates, based on the mean of
publicly available earnings estimates of research analysts as provided by First
Call Investor Service, and current market price to book value and (ii) firm
value (defined as equity value plus debt and preferred stock minus cash and
marketable securities) to LTM revenues, LTM earnings before interest and taxes
("EBIT") and LTM earnings before interest, taxes, depreciation and amortization
("EBITDA"). Robinson-Humphrey averaged the multiples of the publicly traded
comparable companies in order to apply these multiples to Telco Systems' values.
To accurately reflect average values for statistical purposes, Robinson-Humphrey
excluded certain outlying values that differed from the relative groupings of
the other values. Robinson-Humphrey believed that these outlying
                                       46
<PAGE>   58
 
values for certain companies reflect temporary market aberrations that can skew
mean values. Robinson-Humphrey applied these valuation ratios to Telco Systems'
(i) LTM and projected calendar 1998 and 1999 adjusted net income per share, as
adjusted to give effect to tax benefits resulting from the continued use of net
operating loss carryforwards ("Adjusted Net Income Per Share"), (ii) projected
calendar 1998 and 1999 pro forma net income per share, which included pro forma
provisions for income taxes computed at an effective tax rate of 40%, which
assumes no benefits attributable to net operating loss carryforwards ("Pro Forma
Net Income Per Share") and (iii) LTM revenues, LTM EBIT and LTM EBITDA.
Robinson-Humphrey used in its analysis estimates of Telco Systems' projected
adjusted net income per share for calendar 1998 prepared by Robinson-Humphrey's
research analyst for calendar 1998, in consideration of World Access's and Telco
Systems' management's best estimates and judgments regarding future operating
results of Telco Systems. Robinson-Humphrey used in its analysis estimates of
Telco Systems projected pro forma net income per share prepared by World Access
management. Using the preceding multiples, Robinson-Humphrey calculated implied
equity values for Telco Systems ranging from $7.40 to $22.19 per share.
Robinson-Humphrey then calculated an average implied equity value for Telco
Systems of $12.03 per share. Robinson-Humphrey then applied a control premium of
33.4%, which represents the average transaction premiums paid for merger and
acquisition transactions since January 1, 1996 for comparable size transactions,
to these values to derive implied equity values for Telco Systems.
Robinson-Humphrey calculated implied equity values for Telco Systems ranging
from $9.87 per share to $29.60 per share. Robinson-Humphrey then calculated an
average implied equity value for Telco Systems of $16.04 per share.
 
     Analysis of Selected Mergers and Acquisitions.  Robinson-Humphrey reviewed
and analyzed the consideration paid in 35 selected completed and pending mergers
and acquisitions involving telecommunications equipment companies since January
1, 1996. The mergers and acquisitions reviewed by Robinson-Humphrey included
Reltec Corporation's acquisition of Positron Fiber Systems Corporation, Alcatel
Alsthom CIE's pending acquisition of DSC Communications Corporation; Tellabs,
Inc.'s acquisitions of Coherent Communications Systems Corporation and
Steinbrecher Corporation; Lucent Technologies, Inc.'s acquisitions of Yurie
Systems, Inc., Prominet Corporation, Livingston Enterprises, Inc. and Octel
Communications Corporation; Comverse Technology, Inc.'s acquisition of Boston
Technology Incorporated; Davel Communications Group, Inc.'s acquisition of
Communications Central, Inc.; GTE Corporation's acquisition of BBN Corporation,
Cisco Systems, Inc.'s pending acquisition of Summa Four, Inc., and acquisitions
of NetSpeed, LightSpeed International, Inc., Integrated Network Corporation,
Ardent Communications Corporation, Telesend, Inc., Telebit Corporation, Granite
Systems, Inc. and StrataCom, Inc.; US Order, Inc.'s acquisition of Colonial Data
Technologies Corp.; Larscom, Inc.'s acquisition of NetEdge Systems; Yurie
Systems, Inc.'s acquisition of Data Labs, Inc.; DSC Communications Corporation's
acquisition of Celcore, Inc.; McLeodUSA Incorporated's acquisition of
Consolidated Communications; Brooks Fiber Properties, Inc.'s acquisition of
Metro Access Networks, Inc.; ADC Telecommunications, Inc.'s acquisitions of Apex
Group, Inc., Pacific Communications, Photonics Applications and Skyline
Technology, Inc.; and PairGain Technologies, Inc.'s acquisition of Avidia
Systems, Inc. In addition, Robinson-Humphrey reviewed and analyzed the
consideration paid in selected prior mergers and acquisitions involving World
Access, including its acquisitions of NACT, ATI, Galaxy and CIS.
Robinson-Humphrey noted that none of the selected transactions reviewed was
identical to the Merger and that, accordingly, the analysis of comparable
transactions necessarily involves complex considerations and judgments
concerning differences in financial and operating characteristics of the
companies reviewed and other factors that would affect the acquisition values of
comparable transactions. For the transactions involving target companies for
which financial information was available, Robinson-Humphrey calculated
transaction firm value as a multiple of LTM revenues, LTM EBIT and LTM EBITDA
and transaction equity value as a multiple of LTM net income and most recent
book value. In addition, for the target companies that were publicly traded
prior to being acquired, Robinson-Humphrey calculated transaction equity value
per share as a multiple of projected earnings per share, as promulgated by
industry analysts of nationally recognized investment banking firms as of the
date most immediately available prior to the transaction announcement date, and
calculated the implied transaction premiums one day, one week and four weeks
prior to the announcement date. Robinson-Humphrey averaged the multiples for the
selected merger and acquisition transactions in order to apply these multiples
to Telco Systems' values. To accurately reflect average values for statistical
purposes, Robinson-Humphrey excluded certain outlying values that differed
 
                                       47
<PAGE>   59
 
from the relative groupings of the other values. Robinson-Humphrey believed that
these outlying values for certain transactions reflected aberrations that could
skew mean values. Robinson-Humphrey applied the resulting purchase price
multiples, projected price/earnings multiples and transaction premiums to Telco
Systems' (i) LTM revenues, EBITDA, EBIT, net income and book value at August 30,
1998, (ii) calendar 1998 Adjusted Net Income Per Share and calendar 1998 and
1999 Pro Forma Net Income Per Share and (iii) Telco Systems' stock price one
trading day, one week and four weeks prior to the announcement of the Merger
after the market close on June 4, 1998. Robinson-Humphrey derived implied equity
values for Telco Systems ranging from $10.13 to $41.67 per share using purchase
price multiples and $12.61 to $31.31 per share using projected price/earnings
multiples and transaction premiums. Robinson-Humphrey then calculated average
implied equity values per share using these valuation parameters. The purchase
price multiples analysis implied an average equity value for Telco Systems of
$21.81 per share, and the projected price/earnings multiples and transaction
premiums analysis implied an average equity value for Telco Systems of $17.79
per share.
 
     Acquisition Premium Analysis.  Robinson-Humphrey analyzed the premiums paid
for 129 mergers and acquisitions of publicly traded companies with transaction
values in the range of $150 million to $300 million that were announced since
January 1, 1996. The average premiums paid over the targets' stock prices one
trading day prior to the announcement date, one week prior to the announcement
date and four weeks prior to the announcement date were 29.4%, 33.4% and 37.8%,
respectively. Robinson-Humphrey applied these premiums to Telco Systems' stock
price as of June 4, 1998 (the trading day prior to the initial announcement of
the Merger after the market close on June 4, 1998), May 28, 1998 (one week prior
to the initial announcement date) and May 7, 1998 (four weeks prior to the
initial announcement date). The implied equity values for Telco Systems based
upon the average percent premiums paid one day, one week and four weeks prior to
the announcement date applied to Telco Systems' stock price on the corresponding
dates listed above ranged from $13.68 to $14.51 per share, with an average of
$14.16 per share.
 
     Discounted Cash Flow Analysis.  Robinson-Humphrey performed a discounted
cash flow analysis using its research analyst's financial projections for fiscal
1999 and estimates for fiscal 2000 through 2002 based upon guidance from the
managements of World Access and Telco Systems to estimate the net present value
of equity for Telco Systems. Robinson-Humphrey calculated a range of net present
values of Telco Systems' free cash flows (defined as earnings before interest
after taxes plus depreciation and amortization, less capital expenditures and
any increase in net working capital) for the fiscal years ending the last Sunday
in August 1999 through 2002 using discount rates ranging from 15% to 25%.
Robinson-Humphrey calculated a range of net present values of Telco Systems'
terminal values using the same range of discount rates and multiples ranging
from 10.0x to 12.5x projected fiscal 2002 EBIT and also using the same range of
discount rates and multiples ranging from 7.5x to 10.5x projected fiscal 2002
EBITDA. The present values of the free cash flows were then added to the
corresponding present values of the terminal values. After adding Telco Systems'
cash and cash equivalents as of August 30, 1998, Robinson-Humphrey calculated a
range of net present equity values for Telco Systems of $12.56 to $19.78 per
share based upon terminal values of EBIT multiples and a range for Telco Systems
of $11.30 to $19.22 per share based upon terminal values of EBITDA multiples.
Using a discount rate of 20% and terminal value multiples of 11.0x projected
fiscal 2002 EBIT and 9.0x projected fiscal 2002 EBITDA, Robinson-Humphrey
calculated net present equity values for Telco Systems of $15.45 and $14.74 per
share, respectively.
 
     Pro Forma Merger Analysis.  Robinson-Humphrey reviewed certain pro forma
financial effects on World Access resulting from the proposed transaction for
the projected years ending December 31, 1999 and 2000 and the projected quarters
ending December 31, 1998. Robinson-Humphrey performed this analysis using
projections for World Access and for Telco Systems provided by World Access
management, based upon World Access management's best estimates and judgments
regarding future operating results and the synergies anticipated from the
Merger. The pro forma merger analysis was based upon certain assumptions,
including, but not limited to, that the projections developed by World Access,
in consideration of estimates and judgments of the managements of World Access
and Telco Systems, were accurate. Robinson-Humphrey assumed synergies resulting
from the Merger of $10.56 million for the years ending December 31, 1999 and
2000. Robinson-Humphrey assumed that the Merger would be accounted for under the
purchase method of
 
                                       48
<PAGE>   60
 
accounting and would be consummated as of November 30, 1998. In addition,
Robinson-Humphrey assumed a writeoff of 44% of the goodwill resulting from the
transaction as purchased research and development and the availability of tax
credits to offset future income for federal income tax purposes. Using the 20
day average closing price for World Access through October 26, 1998 to calculate
the Exchange Ratio, the Merger was determined to be accretive to World Access'
projected earnings per share for the years ending December 31, 1999 and 2000 and
dilutive to World Access' projected earnings per share for the quarter ending
December 31, 1998. Using a price of $13.00 per share for World Access, the
Merger was determined to be accretive to World Access' projected earnings per
share for the years ending December 31, 1999 and 2000 and dilutive to World
Access' projected earnings per share for the quarter ending December 31, 1998.
 
     The summary set forth above does not purport to be a complete description
of the analyses or data presented by Robinson-Humphrey. The preparation of a
fairness opinion is a complex process and is not necessarily susceptible to
partial analysis or summary description. Robinson-Humphrey believes that the
summary set forth above and their analyses must be considered as a whole and
that selecting portions thereof, without considering all of its analyses, could
create an incomplete view of the processes underlying its analyses and opinion.
Robinson-Humphrey based its analyses on assumptions that it deemed reasonable,
including assumptions concerning general business and economic conditions and
industry-specific factors. The preparation of fairness opinions does not involve
a mathematical or weighing of the results of the individual analyses performed,
but requires Robinson-Humphrey to exercise its professional judgment -- based on
its experience and expertise -- in considering a wide variety of analyses taken
as a whole. Each of the analyses conducted by Robinson-Humphrey was carried out
in order to provide a different perspective on the transaction and to add to the
total mix of information available. Robinson-Humphrey did not form a conclusion
as to whether any individual analysis, considered in insolation, supported or
failed to support an opinion as to fairness. Rather, in reaching its conclusion,
Robinson-Humphrey considered the results of the analyses in light of each other
and ultimately reached its conclusion based on the results of all analyses taken
as a whole. Robinson-Humphrey based its analyses on assumptions it deemed
reasonable, including assumptions concerning general business and economic
conditions and industry-specific factors. The other principal assumptions upon
which Robinson-Humphrey based its analyses are set forth above under the
description of each such analysis. Robinson-Humphrey's analyses are not
necessarily indicative of actual values or actual future results that might be
achieved, which values may be higher or lower than those indicated. Moreover,
Robinson-Humphrey's analyses are not and do not purport to be appraisals or
otherwise reflective of the prices at which businesses actually could be bought
or sold.
 
     In the past, Robinson-Humphrey has been engaged by World Access as an
underwriter and financial advisor and has received customary fees for its
services. In the ordinary course of Robinson-Humphrey's business,
Robinson-Humphrey and its affiliates actively trade in the equity securities of
World Access and Telco Systems for their own accounts and for the accounts of
their customers and, accordingly, may at any time hold a long or a short
position in such securities.
 
     World Access engaged Robinson-Humphrey to render to the Board of Directors
of World Access an opinion with respect to the fairness, from a financial point
of view, to World Access of the Exchange Ratio agreed to in the Merger. World
Access agreed to pay Robinson-Humphrey a fee of $500,000, payable upon the
delivery of the opinion by Robinson-Humphrey. World Access has agreed to
reimburse Robinson-Humphrey for reasonable expenses incurred by
Robinson-Humphrey, including fees and disbursements of counsel, and to indemnify
Robinson-Humphrey against certain liabilities in connection with its engagement,
including liabilities under the federal securities laws.
 
OPINION OF TELCO SYSTEMS' FINANCIAL ADVISOR
 
     Telco Systems engaged Broadview to act as its financial advisor and
requested that Broadview render an opinion regarding the fairness, from a
financial point of view, to Telco Systems stockholders, of the consideration to
be received by such stockholders in the Merger. On June 4, 1998 Broadview
rendered an opinion as to the fairness, from a financial point of view, of the
Merger to Telco Systems stockholders. In connection with its deliberations
regarding the First Amendment, at the meeting of the Telco Systems board of
directors on Monday, October 26, 1998, Broadview rendered its opinion (the
"Broadview Opinion") that, as
                                       49
<PAGE>   61
 
of October 26, 1998, based upon and subject to the various factors and
assumptions set forth in the Broadview Opinion, the Merger Consideration (giving

     In rendering the Broadview Opinion, Broadview relied, without independent
verification, on the accuracy and completeness of all the financial and other
information (including, without limitation, the representations and warranties
contained in the Merger Agreement and First Amendment) that was publicly
available or
 
                                       50

furnished by Telco Systems, World Access or World Access' financial advisor.
Broadview assumed that those projections prepared and provided by the
managements of Telco Systems and World Access were reasonably prepared and
reflected the best available estimates and good faith judgments as to the future
performance of Telco Systems and World Access, respectively. Broadview did not
make or obtain an independent appraisal or valuation of any of World Access' or
Telco Systems' assets. With regard to any analyses relating to valuations of
comparable public companies, the share prices used were for the close of trading
on October 26, 1998, the last trading day before the meeting of the Telco
Systems' board of directors to consider the First Amendment.
 
     The following is a summary explanation of the various sources of
information and valuation methodologies employed by Broadview in conjunction
with rendering the Broadview Opinion. These analyses were presented to the Telco
Systems board of directors at its meeting on October 26, 1998. The summary set
forth below includes the financial analyses used by Broadview and deemed to be
material, but does not purport to be a complete description of analyses
performed by Broadview in arriving at its opinion.
 
     Public Company Comparables Analysis.  Total Market Capitalization/Revenue
("TMC/R") and Price/Earnings ("P/E") multiples indicate the value public markets
place on companies in a particular market segment. Several companies in the
telecommunications equipment market are comparable to Telco Systems based on
market focus, business model and management structure. Broadview reviewed six
selected public company comparables in the communications equipment segment of
the Information Technology ("IT") market from a financial point of view
including each company's: Trailing Twelve Month ("TTM") Revenue; TTM Revenue
Growth; TTM Earnings Before Interest and Taxes ("EBIT") Margin; TTM Net Margin;
Net Cash; Equity Market Capitalization; TTM TMC/R ratio; TTM TMC/EBIT ratio; TTM
P/E ratio; Forward Calendar 1998 TMC/R ratio; Forward Calendar 1998 P/E ratio;
Forward Calendar 1999 TMC/R ratio; and Forward Calendar 1999 P/E ratio. The
public company comparables were selected from the Broadview Barometer, a
proprietary database of publicly-traded IT companies maintained by Broadview and
broken down by industry segment. In order of descending TTM TMC/R, the public
company comparables consist of: (i) ADTRAN, Inc.; (ii) Premisys Communications,
Inc.; (iii) Teltrend, Inc.; (iv) Verilink Corp.; (v) Network Equipment
Technologies, Inc.; and (vi) Larscom, Inc. These comparables have a TTM TMC/R
ratio range of 0.09 to 2.84 with a median of 0.52; TTM TMC/EBIT ratio range of
2.06 to 12.82 with a median of 7.70; TTM P/E ratio range 4.6 to 20.5 with a
median of 19.2; Forward Calendar 1998 TMC/R ratio range of 0.08 to 2.78 with a
median of 0.47; Forward Calendar 1998 P/E ratio range of 12.4 to 30.7 with a
median of 17.6; Forward Calendar 1999 TMC/R ratio range of 0.07 to 2.37 with a
median of 0.41; and a Forward Calendar 1999 P/E ratio range of 9.7 to 16.7 with
a median of 12.9.
 
     The equity value per share range implied by the TTM TMC/R multiples is
$2.56 to $28.34 with a median implied value of $6.64. The equity value per share
range implied by the TTM TMC/EBIT multiples is $2.43 to $6.12 with a median
implied value of $4.37. The equity value per share range implied by the TTM P/E
multiples is $1.95 to $8.70 with a median implied value of $8.15. The equity
value per share implied by the Forward Calendar 1998 TMC/R multiples is $2.51 to
$27.80 with a median implied value of $6.17. The equity value per share implied
by the Forward Calendar 1998 P/E multiples is $4.74 to $11.74 with a median
implied value of $6.74. The equity value per share implied by the Forward
Calendar 1999 TMC/R multiples is $2.60 to $30.78 with a median implied value of
$6.72. The equity value per share implied by the Forward Calendar 1999 P/E
multiples is $11.35 to $19.47 with a median implied value of $15.10.
 
     Evaluation of World Access.  Broadview compared the ranges and medians of
several companies that are comparable to World Access, based on market focus,
revenue size, business model and management structure, with the multiples
implied by World Access' October 26, 1998 share price of $18.313, and its
current and projected performance. In order to account for the pending Resurgens
Transaction, two sets of comparable companies were used and are listed below. In
order of descending TTM TMC/R, the public company comparables in the
telecommunications equipment and systems integration market consist of: (i)
Excel Switching Corp.; (ii) ADTRAN, Inc.; (iii) Advanced Fibre Communications,
Inc.; (iv) SR Telecom, Inc.; (v); Comarco, Inc. (vi) Digital Microwave Corp.
(vii) LCC International, Inc.; and (viii) P-COM, Inc. In order of descending TTM
TMC/R, the public company comparables in the telecommunications services market
consist of: (i) Viatel, Inc.; (ii) RSL Communications, Ltd.; (iii) PRIMUS
Telecommunications Group, Inc.; (iv) STAR Telecommunications, Inc.; and (v)
Startec Global Communications Corp.
                                       51

     Transaction Comparables Analysis.  Valuation statistics from transaction
comparables indicate the Adjusted Price/Revenue ("P/R"), Adjusted Price/Earnings
Before Interest and Taxes ("P/EBIT"), and Adjusted Price/Earnings Before
Interest, Taxes, Depreciation and Amortization ("P/EBITDA") multiples acquirers
have paid for comparable companies in a particular market segment. Adjusted
Price is the acquisition consideration adjusted to add debt and subtract cash on
the seller's balance sheet at the time of the acquisition, if known. Broadview
reviewed fourteen comparable public and private company merger and acquisition
("M&A") transactions from 1996 through the present involving sellers sharing
many characteristics with Telco Systems including size, markets served and
business model. Transactions were selected from Broadview's proprietary database
of published and confidential M&A transactions in the IT industry. These
transactions represent fourteen selected sellers in the hardware equipment
segment of the IT market. In order of descending P/R multiple, the fourteen
public and private company transactions used are the acquisition of: (i) Avidia
Systems, Inc. by Pairgain Technologies, Inc.; (ii) Coherent Communications
Systems Corp. by Tellabs, Inc.; (iii) Positron Fiber Systems Corp. by Reltec
Corp.; (iv) Netvantage, Inc. by Cabletron Systems, Inc.; (v) NACT by World
Access, Inc.; (vi) Teledata Communications Ltd. by ADC Telecommunications, Inc.;
(vii) Summa Four, Inc. by Cisco Systems, Inc.; (viii) Innova Corp. by Digital
Microwave Corp.; (ix) Micom Communications Corp. by Northern Telecom Ltd.; (x)
Microcom, Inc. by Compaq Computer Corp.; (xi) Stratus Computers, Inc. by Ascend
Communications, Inc.; (xii) Centigram Communications Corp. (Customer Premises
Equipment business unit) by Mitel Corp.; (xiii) Tadiran Telecommunications Ltd
by ECI Telecom, Inc.; and (xiv) Shiva Corp. by Intel Corp.
 
     The P/R multiples of the fourteen public and private seller transactions
range from 0.78 to 9.40 with a median of 1.97. The P/EBIT multiples of the seven
public seller transactions, where meaningful data is available, range from 11.62
to 60.95 with a median of 30.72. The P/EBITDA multiples of the seven public
seller transactions, where meaningful data is available, range from 4.55 to
30.42 with a median of 15.25.
 
     The equity value per share range implied by the P/R multiples of the
fourteen public and private seller transaction comparables is $9.02 to $89.78
with a median implied value of $20.16. The equity value per share range implied
by the P/EBIT multiples of the seven public seller transactions, where
meaningful data is available, is $5.71 to $22.61 with a median implied value of
$12.25. The equity value per share range implied by the P/EBITDA multiples of
the seven public seller transactions, where meaningful data is available, is
$5.06 to $23.95 with a median implied value of $12.87.
 
     Transaction Premiums Paid Analysis.  An analysis of premiums paid in
comparable public transactions, while generally appropriate for public sellers,
is not as applicable for the Merger, because the price of the Telco Systems
Common Stock has been linked to the price of the World Access Common Stock as a
result of the Exchange Ratio formula established in the original Merger
Agreement. Premiums paid in comparable public seller transactions typically
indicate the amount of consideration acquirers are willing to pay above the
seller's equity market capitalization. In this analysis, the value of
consideration paid in transactions involving stock is computed using the buyer's
stock price immediately prior to announcement, while the seller's equity market
capitalization is measured one day prior. Broadview reviewed 32 comparable M&A
transactions involving selected hardware companies from January 1, 1996 to the
present with total consideration above $100 million. Transactions were selected
from Broadview's proprietary database of published and confidential M&A
transactions in the IT industry. In order of descending premium paid based on
the seller's stock price one trading day prior to announcement, the selected
hardware transactions used were the acquisition of: (i) ILC Technology, Inc. by
BEC Group, Inc.; (ii) DSC Communications Corp. by Alcatel Alsthom SA; (iii)
Norand Corp. by Western Atlas, Inc.; (iv) Microcom, Inc. by Compaq Computer
Corp.; (v) Tandem Computers, Inc. by Compaq Computer Corp.; (vi) Brooktree Corp.
by Rockwell International Corp.; (vii) Shiva Corp. by Intel Corp.; (viii) Bay
Networks, Inc. by Northern Telecom, Ltd.; (ix) Digital Equipment Corporation by
Compaq Computer Corp.; (x) MAS Technology Ltd. by Digital Microwave Corp.; (xi)
Coherent Communications Systems Corp. by Tellabs, Inc.; (xii) Augat, Inc. by
Thomas & Betts Corp.; (xiii) Advanced Logic Research by Gateway 2000, Inc.;
(xiv) Cascade Communications Corp. by Ascend Communications, Inc.; (xv) Chips &
Technologies, Inc. by Intel Corp.; (xvi) Stratacom, Inc. by Cisco Systems, Inc.;
(xvii) Positron Fiber Systems, Inc. by Reltec Corp.; (xviii) Cray Research, Inc.
by Silicon Graphics, Inc.; (xix) Cyrix Corp. by National Semiconductor Corp.;
(xx) Teledata Communications

Ltd by ADC Telecommunications, Inc.; (xxi) Octel Communications Corp. by Lucent
Technologies, Inc.; (xxii) BENCHMARQ Microelectronics, Inc. by Unitrode Corp.;
(xxiii) Stratus Computers, Inc. by Ascend Communications, Inc.; (xxiv) Zycon
Corp. by Hadco Corp.; (xxv) Amphenol Corp. by Kohlberg, Kravis Roberts & Co.;
(xxvi) U.S. Robotics Corp. by 3Com Corp.; (xxvii) Zilog, Inc. by Texas Pacific
Group; (xxviii) Yurie Systems, Inc. by Lucent Technologies, Inc.; (xxix) Boston
Technology, Inc. by Comverse Technology, Inc.; (xxx) Tadiran Telecommunications
Ltd by ECI Telecom, Inc.; (xxxi) Netstar, Inc. by Ascend Communications, Inc.;
and (xxxii) Micom Communications Corp. by Northern Telecom, Inc.
 
     Based upon Broadview's analysis of premiums paid in selected comparable
hardware transactions, Broadview found that premiums (discounts) paid to
sellers' equity market capitalizations one day prior to announcement date (using
the buyer's share price on the day prior to the announcement date of the
transaction to calculate consideration in stock transactions) ranged from
(14.3%) to 108.7% with a median of 21.5%.
 
     The equity value per share range implied by the premiums paid to the share
price one day prior to the announcement of the companies' agreement in principle
on October 13, 1998 regarding the Minimum Nominal Value is $5.46 to $13.31 with
a median implied value of $7.75. The implied premium of the $12.00 Minimum
Nominal value reflects an 88.2% premium paid to the price of the Telco Systems
Common Stock one day prior to the October 13, 1998 announcement, which exceeds
the median of the premiums paid in selected comparable hardware transactions
despite the fact there may have already been an implied premium in price of the
Telco Systems Common Stock due to the June 4, 1998 announcement of the Merger
Agreement.
 
     Stock Performance Analysis.  For comparative purposes, Broadview examined
the weekly historical volume and trading prices and the daily relative share
prices for both World Access and Telco Systems common stock. Broadview examined
the following: (i) World Access and Telco Systems actual share prices and
trading volumes from October 17, 1997 to October 26, 1998; (ii) World Access,
Telco Systems and their respective public company comparables indexed share
prices from October 17, 1997 to October 26, 1998; (iii) relative ratio of Telco
Systems to World Access actual share prices from October 17, 1997 to October 26,
1998.
 
     Relative Contribution Analysis.  A relative contribution analysis measures
each of the merging companies' contributions to items such as Revenue and Net
Income on a percentage basis. Broadview examined the projected relative
contributions for the projected calendar year ending December 31, 1998 and the
for the calendar year ending December 31, 1999, based upon internal estimates
for World Access (assuming the Resurgens Transaction is not completed) and Telco
Systems on Revenue, EBIT, Pretax Income and Net Income bases.
 
     Telco Systems' projected relative contribution for Revenue for the calendar
year ending December 31, 1998 and for the calendar year ending December 31, 1999
is 37.5% and 35.5%, respectively. Telco Systems' projected relative contribution
for EBIT for the calendar year ending December 31, 1998 and for the calendar
year ending December 31, 1999 is 6.5% and 23.6%, respectively. Telco Systems'
projected relative contribution for Pretax Income for the calendar year ending
December 31, 1998 and for the calendar year ending December 31, 1999 is 9.3% and
25.1%, respectively. Telco Systems' projected relative contribution for Net
Income for the calendar year ending December 31, 1998 and for the calendar year
ending December 31, 1999 is 12.8% and 28.6%, respectively.
 
     Broadview also examined the projected relative contributions during the
calendar year ending December 31, 1999, based upon internal projections for
World Access (assuming the Resurgens Transaction is completed) and Telco Systems
on Revenue, EBIT, Pretax Income and Net Income bases. Telco Systems' projected
relative contribution for Revenue for the calendar year ending December 31, 1999
is 17.0%. Telco Systems' projected relative contribution for EBIT for the
calendar year ending December 31, 1999 is 18.2%. Telco Systems' projected
relative contribution for Pretax Income for the calendar year ending December
31, 1999 is 19.5%. Telco Systems' projected relative contribution for Net Income
for the calendar year ending December 31, 1999 is 22.8%.

     Relative Ownership Analysis.  A relative ownership analysis measures each
of the merging companies' (assuming an all stock transaction) relative equity
ownership and relative entity values (net of cash) at various exchange ratios.
If World Access does not complete the Resurgens Transaction, the implied equity
ownership, using relative equity values, is 24.2% for Telco Systems and 75.8%
for World Access, and the implied entity ownership, using relative entity
values, is 19.7% for Telco Systems and 80.3% for World Access.
 
     If World Access completes the Resurgens Transaction, the implied equity
ownership, using relative equity values, is 21.8% for Telco Systems and 78.2%
for World Access, and the implied entity ownership, using relative entity
values, is 17.7% for Telco Systems and 82.3% for World Access.
 
     Pro Forma Purchase Model Analysis.  A pro forma merger analysis calculates
the EPS accretion (dilution) of the pro forma combined entity taking into
consideration various financial affects which will result from a consummation of
the Merger. This analysis relies upon certain financial and operating
assumptions provided by World Access and Telco Systems management and on
publicly available data about World Access and Telco Systems. Based on
management forecasts for World Access (assuming the Resurgens Transaction is not
completed) and Telco Systems, the pro forma purchase analysis indicates EPS
accretion to World Access stockholders for the fiscal year ending December 31,
1999 of $0.07 or 4.7%.
 
     Broadview also employed a pro forma purchase analysis to evaluate the
accretion (dilution) to the pro forma combined entity in the event the Resurgens
Transaction is completed. Based on management forecasts for World Access,
Resurgens and Telco Systems, the pro forma purchase analysis indicates EPS
accretion (dilution) to World Access stockholders for the fiscal year ending
December 31, 1999 of $0.03 or 1.9%
 
     Consideration of the Discounted Cash Flows Valuation Methodology.  While
discounted cash flows analysis is a commonly used valuation methodology,
Broadview did not employ such an analysis for the purposes of this opinion.
Discounted cash flows analysis is most appropriate for companies which exhibit
relatively steady or somewhat predictable streams of future cash flows. Given
the uncertainty in estimating both Telco Systems' future cash flows and
sustainable long-term growth rate, Broadview considered a discounted cash flows
analysis inappropriate for valuing Telco Systems.
 
     The Telco Systems board of directors selected Broadview as its financial
advisor on the basis of Broadview's reputation and experience in the information
technology sector and the hardware industry in particular, as well as
Broadview's historical relationship with Telco Systems. Pursuant to the terms of
an engagement letter between Telco Systems and Broadview, the fees payable by
Telco Systems to Broadview upon completion of the Merger are based upon the
consideration to be received by Telco Systems pursuant to the Merger and are
approximately $1.7 million. Telco Systems paid Broadview fees totaling $400,000
in connection with rendering its opinions as to the fairness of the
consideration to be received by Telco Systems stockholders in the Merger which
will be credited to the fees payable by Telco Systems upon completion of the
Merger. In addition, retainer fees of approximately $130,000 paid by Telco
Systems to Broadview will also be credited to the fees payable by Telco Systems
upon completion of the Merger. Broadview will be reimbursed by Telco Systems for
certain of its expenses incurred in connection with its engagement. The terms of
the fee arrangement with Broadview, which Telco Systems and Broadview believe
are customary in transactions of this nature, were negotiated at arms' length
between Telco Systems and Broadview, and the Telco Systems board of directors
was aware of the nature of the fee arrangement, including the fact that a
significant portion of the fees payable to Broadview is contingent upon
completion of the Merger.
 
     The above summary of the presentations by Broadview to the Telco Systems
board of directors does not purport to be a complete description of such
presentations or of all the advice rendered by Broadview. Broadview believes
that its analyses and the summary set forth above must be considered as a whole
and that selecting portions of its analyses, without considering all analyses,
could create an incomplete view of the process underlying the analyses set forth
in Broadview's presentations to the Telco Systems board of directors and in the
Broadview Opinion. The Broadview Opinion is necessarily based upon market,
economic, financial and other conditions as they existed and could be evaluated
as of the date of the Broadview Opinion. The Broadview Opinion expresses no
opinion as to the price at which the World Access Common Stock will trade at any
time. In performing its analyses, Broadview made numerous assumptions with
respect to hardware industry performance and general economic conditions, many
of which are beyond the control of Telco
                                       54

Systems or World Access. The analyses performed by Broadview are not necessarily
indicative of actual values or actual future results, which may be significantly
more or less favorable than suggested by such analyses.
 
FEDERAL INCOME TAX CONSEQUENCES
 
     The following discussion summarizes the material federal income tax
consequences of the Merger to Telco Systems and holders of Telco Systems Common
Stock and to World Access. The discussion is based on current law and summarizes
the opinions of Rogers & Hardin LLP, counsel to World Access, and Skadden, Arps,
Slate, Meagher & Flom LLP, counsel to Telco Systems. The discussion does not
address aspects of federal taxation other than income taxation, nor does it
address all aspects of federal income taxation, including, without limitation,
aspects of federal income taxation that may be applicable to particular
stockholders, such as stockholders who are dealers in securities, foreign
persons or those who acquired their Telco Systems Common Stock in a compensation
transaction. The discussion also does not address the federal income tax
consequences of the Merger to holders of options to purchase Telco Systems
Common Stock or any state, local or foreign tax consequences of the Merger.
 
     HOLDERS OF TELCO SYSTEMS COMMON STOCK ARE URGED TO CONSULT THEIR TAX
ADVISORS WITH RESPECT TO THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES
OF THE TELCO SYSTEMS MERGER.
 
     World Access and Telco Systems each have received opinions (the "Tax
Opinions") from their respective tax counsel, Rogers & Hardin LLP and Skadden,
Arps, Slate, Meagher & Flom LLP, to the effect that, on the basis of certain
representations, and subject to certain assumptions and limitations, stated in
the Tax Opinions, the Merger will qualify as a tax-free reorganization under
Section 368 of the Code and that each of World Access, Merger Sub and Telco
Systems will be a party to the reorganization within the meaning of Section
368(b) of the Code. It is a condition to World Access' and Telco Systems'
obligations to effect the Merger that the Tax Opinions shall have been reissued
in substantially the same form as of the Effective Time. Although the condition
to receive the Tax Opinions at the closing of the Merger is waivable, if the
condition to receive the Tax Opinions at the closing of the Merger is waived by
either World Access or Telco Systems, then the stockholders for whose benefit
such opinion was initially sought shall be re-solicited.
 
     No ruling has been or will be obtained from the Internal Revenue Service
(the "IRS") with respect to the Merger. The Tax Opinions are not binding on the
IRS or the courts, and no assurance can be given that the IRS would not be able
to successfully challenge the conclusions expressed in the Tax Opinions.
 
     Consequences to Holders of Telco Systems Common Stock.  If, in accordance
with the opinions referred to above, the Merger is treated as a reorganization
within the meaning of Section 368(a) of the Code, and World Access, Merger Sub
and Telco Systems is each a party to that reorganization under Section 368(b) of
the Code, then, in the opinion of Skadden, Arps, Slate, Meagher & Flom LLP, the
following is a summary of the material federal income tax consequences of the
Merger to a holder:
 
     The federal income tax consequences of the Merger to a holder of Telco
Systems Common Stock will depend on whether the holder exchanges its Telco
Systems Common Stock for solely World Access Common Stock, or a combination of
cash and World Access Common Stock.
 
     Exchange Solely for World Access Common Stock.  If pursuant to the Merger a
holder exchanges all of the shares of Telco Systems Common Stock actually owned
by such holder solely for shares of World Access Common Stock, such holder will
not recognize any gain or loss except in respect of cash received in lieu of a
fractional share of World Access Common Stock (as discussed below). The
aggregate adjusted tax basis of the shares of World Access Common Stock received
in that exchange will be equal to the aggregate adjusted tax basis of the shares
of Telco Systems Common Stock surrendered therefor, and the holding period of
such World Access Common Stock will include the period during which such shares
of Telco Systems Common Stock were held. If a holder has differing bases and/or
holding periods in respect of such holder's shares of Telco Systems Common
Stock, such holder should consult his or her tax advisor prior to the exchange
with regard to identifying the bases and/or holding periods of the particular
shares of World Access Common Stock received in the exchange.
 
                                       55
<PAGE>   67
 
     Exchange for World Access Common Stock and Cash.  If pursuant to the Merger
a holder exchanges all of the shares of Telco Systems Common Stock actually
owned by such holder for a combination of World Access Common Stock and cash,
such holder will realize gain or loss equal to the difference between (i) the
sum of cash and the fair market value of World Access Common Stock received and
(ii) such holder's adjusted tax basis in the shares of Telco Systems Common
Stock surrendered. Any such gain will only be recognized to the extent of the
cash received. However, any such loss will not be recognized, but will be
reflected in the tax basis of the World Access Common Stock received.
Accordingly, a holder generally will be able to recognize any such loss as an
offset to the amount realized upon a subsequent sale or exchange of such World
Access Common Stock. For this purpose, gain or loss must be calculated
separately for each identifiable block of shares surrendered in the exchange,
and a loss recognized on one block of shares of Telco Systems Common Stock
cannot be used to offset a gain recognized on another block of shares of Telco
Systems Common Stock. Any such recognized gain will be treated as capital gain
unless the cash received has the effect of the distribution of a dividend, in
which case the gain would be treated as a dividend to the extent of the holder's
ratable share of Telco Systems' accumulated earnings and profits.
 
     In general, the determination as to whether the gain recognized in that
exchange will be treated as capital gain or dividend income depends upon whether
and to what extent that exchange reduces the holder's deemed percentage stock
ownership of World Access. For purposes of that determination, a holder is
treated as if such holder first exchanged all of such holder's shares of Telco
Systems Common Stock solely for shares of World Access Common Stock and then
World Access immediately redeemed (the "deemed redemption") a portion of such
World Access Common Stock in exchange for the cash the holder actually received.
The gain recognized in that exchange will be treated as capital gain if the
deemed redemption is (i) "not essentially equivalent to a dividend" or (ii)
"substantially disproportionate" with respect to the holder.
 
     Whether the deemed redemption is "not essentially equivalent to a dividend"
with respect to a holder will depend upon the holder's particular circumstances.
At a minimum, however, in order for the deemed redemption to be "not essentially
equivalent to a dividend," the deemed redemption must result in a "meaningful
reduction" in the holder's deemed percentage stock ownership of World Access. In
general, that determination requires a comparison of (i) the percentage of the
outstanding World Access Common Stock the holder is deemed actually and
constructively to have owned immediately before the deemed redemption and (ii)
the percentage of the outstanding World Access Common Stock actually and
constructively owned by the holder immediately after the deemed redemption. The
deemed redemption will be "substantially disproportionate" with respect to a
holder if the percentage described in (ii) above is less than 80% of the
percentage described in (i) above. The IRS has ruled that a reduction in the
percentage stock ownership of a minority stockholder in a publicly held
corporation whose relative stock interest is minimal and who exercises no
control with respect to corporate affairs is a "meaningful reduction."
 
     In applying the foregoing tests, under certain attribution rules proscribed
in Section 318 of the Code, a stockholder is deemed to own stock owned and, in
some cases, constructively owned by certain family members, by certain estates
and trusts of which the holder is a beneficiary, and by certain affiliated
entities, as well as stock subject to an option actually or constructively owned
by the shareholder or such other person. As these rules are complex, each holder
that believes he or she may be subject to these rules should consult his or her
tax advisor.
 
     Under the foregoing tests, in most circumstances, gain recognized by a
holder that exchanges its shares of Telco Systems Common Stock for a combination
of shares of World Access Common Stock and cash will be treated as capital gain,
and will be long-term capital gain if the holding period for such shares was
greater than one year as of the date of the exchange.
 
     The aggregate tax basis of the shares of World Access Common Stock received
by a holder that exchanges shares of Telco Systems Common Stock for a
combination of shares of World Access Common Stock and cash pursuant to the
Merger, will be the same as the aggregate tax basis of the shares of Telco
Systems Common Stock surrendered therefor, decreased by the cash received and
increased by any recognized gain (whether capital gain or dividend income). The
holding period of the shares of World Access
 
                                       56
<PAGE>   68
 
Common Stock will include the holding period of the shares of Telco Systems
Common Stock surrendered therefor.
 
     If such a holder has differing bases and/or holding periods in respect of
his or her shares of Telco Systems Common Stock, such holder should consult his
or her tax advisor prior to the exchange with regard to identifying the
particular shares of Telco Systems Common Stock to be surrendered in the
exchange and the particular bases and/or holding periods of the particular
shares of World Access Common Stock such holder receives in the exchange.
 
     Cash Received in Lieu of a Fractional Share.  Cash received in lieu of a
fractional share of World Access Common Stock will be treated as received in
redemption of such fractional share and gain or loss will be recognized,
measured by the difference between the amount of cash received and the portion
of the basis of the share of Telco Systems Common Stock allocable to such
fractional interest. Such gain or loss will constitute capital gain or loss, and
will be long-term capital gain or loss if the holding period for such shares of
Telco Systems Common Stock was greater than one year as of the date of the
exchange.
 
     Backup Withholding.  Payments in respect of Telco Systems Common Stock may
be subject to informational reporting to the IRS and to a 31% back-up
withholding tax. Backup withholding will not apply, however, to a payment to a
holder of Telco Systems Common Stock or other payee if such holder or payee
completes and signs the substitute Form W-9 that will be included as part of the
letter of transmittal to be mailed to the stockholders of Telco Systems or
otherwise proves to World Access and the Exchange Agent (as defined below) that
it is exempt from backup withholding.
 
     Consequences to Companies.  If, in accordance with the opinions referred to
above, the Merger is treated as a reorganization within the meaning of Section
368(a) of the Code, and World Access, Merger Sub, and Telco Systems is each a
party to that reorganization under Section 368(b) of the Code, then, in the
opinion of Rogers & Hardin LLP, no gain or loss will be recognized by World
Access, Merger Sub or Telco Systems in the Merger.
 
LIMITATIONS ON RESALES BY AFFILIATES
 
     All shares of World Access Common Stock received by Telco Systems
stockholders in the Merger will be freely transferable, except that shares of
World Access Common Stock received by persons who are deemed to be "affiliates"
of Telco Systems prior to the Merger may be resold by them only in transactions
permitted by the resale provisions of Rule 145 ("Rule 145") or Rule 144 (in the
case of such persons who become affiliates of World Access), each as promulgated
under the Securities Act, or otherwise in compliance with (or pursuant to an
exemption from) the registration requirements of the Securities Act. Persons
deemed to be "affiliates" of Telco Systems or World Access are those individuals
or entities that control, are controlled by, or are under common control with,
such party and generally include executive officers and directors of such party
as well as certain principal stockholders of such party. The Merger Agreement
requires Telco Systems to use all reasonable efforts to cause each of its
affiliates to execute a written agreement to the effect that such person will
not offer or sell or otherwise dispose of any of the shares of World Access
Common Stock issued to such person in or pursuant to the Merger except in
compliance with the Securities Act and the rules and regulations promulgated by
the Commission thereunder. This Joint Proxy Statement/Prospectus does not cover
any resales of World Access Common Stock received by affiliates of Telco Systems
in the Merger.
 
ACCOUNTING TREATMENT
 
     The Merger will be accounted for by World Access under the purchase method
of accounting for business combinations.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
     In considering the recommendation of the Telco Systems board of directors
with respect to the Merger, stockholders of Telco Systems should be aware that,
as described below, certain members of Telco Systems' management and board of
directors may have interests in the Merger that are different from, or in
addition to,
 
                                       57
<PAGE>   69
 
the interests of stockholders of Telco Systems generally, and these differences
may create potential conflicts of interest. In addition, one executive officer
of Telco Systems, Dr. William Smith, is a member of the Telco Systems board of
directors. The Telco Systems board of directors was aware of these interests
when it approved the Merger and the Merger Agreement. Except as described below,
such persons have, to the knowledge of Telco Systems and World Access, no
material interest in the Merger apart from those of stockholders of Telco
Systems generally.
 
     World Access Board of Directors.  The size of the World Access board of
directors is currently fixed at six members, five of whom are the current board
members with one position vacant. Pursuant to the terms of the Merger Agreement,
the vacancy on the World Access board of directors will be filled at the
Effective Time by a person selected by mutual agreement of Telco Systems and
World Access. As of the date of this Joint Proxy/Prospectus, no determination
has been made by the companies as to who will fill such vacancy.
 
     Telco Systems Officers.  Pursuant to the terms of the Merger Agreement, the
officers of Telco Systems immediately prior to the Effective Time will be the
initial officers of Telco Systems, as the Surviving Corporation.
 
     Telco Systems Stock Options.  All of the executive officers and directors
of Telco Systems hold options to purchase shares of Telco Systems Common Stock.
In accordance with the terms of the various director and employee stock option
plans maintained by Telco Systems and the terms of the Merger Agreement, all
options to purchase shares of Telco Systems Common Stock outstanding as of June
4, 1998 will vest in full upon consummation of the Merger and all outstanding
options to purchase shares of Telco Common Stock will be converted into similar
stock options with respect to World Access Common Stock, adjusted to account for
the Exchange Ratio and the Minimum Nominal Value. As of the Telco Systems Record
Date, all executive officers of Telco Systems as a group held unexercisable
options to purchase an aggregate of 132,982 shares of Telco Systems Common
Stock, and all directors of Telco Systems as a group held unexercisable options
to purchase an aggregate of 47,147 shares of Telco Systems Common Stock.
 
     Telco Systems Senior Executive Termination Benefits Agreements.  Telco
Systems is a party to a Senior Executive Termination Benefits Agreement with its
President and Chief Executive Officer, Dr. William Smith (the "Smith
Agreement"), and is a party to Senior Executive Termination Benefits Agreements
(each, a "Severance Agreement" and, together with the Smith Agreement, the
"Agreements") with each of William Stuart, Vice President and Chief Financial
Officer, Richard Nardone, Vice President, Corporate Resources, David LeBeau,
Vice President of Sales, and Daniel Bettencourt, Vice President of Operations
(each, an "Executive"), which Agreements provide for certain severance payments
to be made and benefits to be provided to each of Dr. Smith and the Executives
upon a qualifying termination of his employment following a "Change in Control"
of Telco Systems. Stockholder approval of the Merger will constitute a Change in
Control under the Agreements.
 
     In accordance with the terms of the Smith Agreement, in the event Dr.
Smith's employment is terminated within three years following a Change in
Control (i) by Telco Systems for any reason other than death, Disability (as
defined in the Smith Agreement) or for Cause (as defined in the Smith Agreement)
or (ii) by Dr. Smith for any of the reasons set forth in the Smith Agreement
(including the assignment to Dr. Smith of any duties which are (as determined by
him in good faith) substantially inconsistent with his positions, duties,
responsibilities or status with Telco Systems immediately prior to the Change in
Control (such assignment referred to herein as "Good Reason")), Dr. Smith will
be entitled to the following: (a) a lump sum cash payment equal to the sum of
(i) 1.5 times Dr. Smith's annual base salary as of the date of termination and
(ii) an amount equal to the highest annual bonus paid or payable to Dr. Smith
with respect to any consecutive 12-month period during the three years prior to
the date of termination; and (b) the continuation of employee welfare benefits
(including, without limitation, to life, accident, disability, health and dental
insurance plans) for 18 months following the date of termination. If Dr. Smith's
employment is terminated in a manner that gives rise to the severance payments
described herein, he will be entitled to receive a cash severance payment
approximately equal to $600,000.
 
     In accordance with the terms of the Severance Agreements, in the event an
Executive's employment is terminated within 18 months following a Change in
Control (i) by Telco Systems for any reason other than
                                       58
<PAGE>   70
 
death, Disability (as defined in the Severance Agreements) or for Cause (as
defined in the Severance Agreements) or (ii) by the Executive for the reasons
set forth in the Severance Agreements (including Good Reason), the Executive
will be entitled to the following: (a) thirteen payments, each equal to the sum
of (i) one-twelfth times the Executive's annual base salary as of the date of
termination and (ii) one-twelfth times the highest annual bonus paid or payable
to the Executive with respect to any consecutive 12-month period during the
three years prior to the date of termination; and (b) the continuation of
employee welfare benefits (including, without limitation, short-term,
disability, health, dental and executive medical insurance coverage) for
thirteen months following the date of termination. An Executive may elect to
receive the payments described in clause (a) above in a single lump sum payment.
If each Executive's employment is terminated in a manner that gives rise to the
severance payments described herein, the following Executives would be entitled
to receive the following approximate cash severance payments: Mr. Stuart,
$263,000; Mr. Nardone, $195,000; Mr. LeBeau $256,000; and Mr. Bettencourt,
$178,000.
 
     In the Merger Agreement, World Access has acknowledged and agreed that Dr.
Smith and the Executives will be entitled, as a result of the Merger and the
related change in their job responsibilities, to terminate their employment with
Telco Systems for Good Reason and receive the termination benefits under the
Agreements. However, in connection with the execution of the Merger Agreement,
World Access has entered into agreements with Dr. Smith and each Executive other
than Mr. Stuart (each, a "World Access Agreement"), pursuant to which World
Access agreed to grant to each of Dr. Smith and Messrs. Bettencourt, Nardone and
LeBeau, as of the Effective Time, an option (each, an "Option") to purchase
150,000, 30,000, 20,000 and 100,000 shares of World Access Common Stock,
respectively, at an exercise price per share subject to the Option equal to the
lesser of (a) the fair market value of a share of World Access Common Stock on
the Closing Date and (b) $32.00. These options vest at a rate of 25% per year
upon each of the four anniversaries of the date of grant. In consideration for
the grant of the Option, each of Dr. Smith and Messrs. Bettencourt, Nardone and
LeBeau has agreed that he will not terminate his employment for Good Reason
following stockholder approval of the Merger if Good Reason results solely from
the fact that, upon consummation of the Merger, Telco Systems will be a wholly
owned subsidiary of a publicly traded company. However, each of Dr. Smith and
Messrs. Bettencourt, Nardone and LeBeau may forfeit the unvested portion of the
Option at any time between the 180th day and the 210th day (between the 360th
and 390th day, in the case of Dr. Smith) following the Closing Date and,
notwithstanding the World Access Agreement, may terminate his employment and
receive the termination benefits in accordance with the terms of the applicable
Agreement. It is currently expected that, upon consummation of the Merger, Mr.
Stuart will exercise his rights under his Severance Agreement.
 
     Indemnification; Insurance.  Under the Merger Agreement, World Access has
agreed that the certificate of incorporation of the Surviving Corporation in the
Merger will contain the indemnification provisions set forth in the Telco
Systems certificate of incorporation (the "Telco Systems Certificate") and that
such provisions will not be amended, repealed or otherwise modified for a period
of six years from the Effective Time in any manner that would adversely affect
the rights thereunder of individuals who at the Effective Time were directors,
officers, employees, fiduciaries, or agents of Telco Systems. World Access has
also agreed that from and after the Effective Time, World Access and the
Surviving Corporation shall indemnify and hold harmless each present and former
director and officer of Telco Systems against any costs or expenses (including
reasonable attorneys' fees), judgments, fines, losses, claims, damages or
liabilities incurred in connection with any claim, action, suit, proceeding or
investigation, whether civil, criminal, administrative or investigative, arising
out of or pertaining to matters existing or occurring at or prior to the
Effective Time, whether asserted or claimed prior to, at or after the Effective
Time, to the fullest extent that Telco Systems would have been permitted under
Delaware law and its charter documents (each as in effect on June 4, 1998) to
indemnify such persons. Finally, World Access has also agreed to provide for six
years after the Effective Time liability insurance covering acts or omissions
occurring prior to the Effective Time with respect to those persons who were
covered by Telco Systems' directors' and officers' liability insurance policy on
terms with respect to such coverage and amounts no less favorable than those in
effect on the date of the Merger Agreement, provided that World Access will not
be required to pay more than 150% of the current amount paid by Telco Systems to
maintain such insurance. In connection with its obligation as described in the
immediately foregoing sentence, World Access is permitted under the Merger
Agreement to substitute
                                       59
<PAGE>   71
 
policies of World Access or its subsidiaries containing terms with respect to
coverage and amount no less favorable to the directors and officers in question.
 
REGULATORY MATTERS
 
     Under the HSR Act and the rules promulgated thereunder by the FTC, certain
acquisition transactions may not be consummated unless notice has been given and
certain information has been furnished to the Antitrust Division and the FTC and
specified waiting period requirements have been satisfied. World Access and
Telco Systems each filed with the Antitrust Division and the FTC a Notification
and Report Form with respect to the Merger on July 31, 1998. The required
waiting period under the HSR Act was terminated by the FTC on August 28, 1998.
At any time before or after the Effective Time, the FTC or the Antitrust
Division could take such action under the antitrust laws as it deems necessary
or desirable in the public interest, including seeking to enjoin the Merger or
seeking the divestiture of Telco Systems by World Access, in whole or in part,
or the divestiture of substantial assets of World Access, Telco Systems or their
respective subsidiaries. State attorneys general and private parties may also
bring legal actions under the federal or state antitrust laws under certain
circumstances.
 
OPERATIONS FOLLOWING THE MERGER
 
     Following the Merger, the Surviving Corporation initially will be managed
by Telco Systems' operating management and will become the Transport and Access
Systems Group of World Access. Promptly following the Merger, World Access
intends to integrate the operations of its current Transport and Access Systems
Group into, and under the supervision of, the Surviving Corporation. In doing
so, World Access may relocate certain of the operations of its current
subsidiaries, including ATI and Sunrise, to Telco Systems' facilities in
Norwood, Massachusetts and Fremont, California. The Surviving Corporation will
otherwise continue its operations substantially as such operations were
conducted by Telco Systems prior to the Merger.
 
APPRAISAL RIGHTS
 
     Holders of Telco Systems Common Stock will not have the right to elect to
have the fair value of their shares of Telco Systems Common Stock judicially
appraised and paid to them in cash in connection with the Merger unless World
Access elects to pay a portion of the Merger Consideration in cash. Section 262
of the DGCL ("Section 262") provides appraisal rights to stockholders of
Delaware corporations in connection with certain mergers and consolidations.
Under Section 262, appraisal rights are not available to the stockholders of a
corporation that is a party to a merger if the corporation's stock is listed on
a national securities exchange or quoted on Nasdaq as of the record date set to
determine the stockholders entitled to receive notice of and to vote at the
meeting of stockholders to approve the merger so long as the consideration to be
received by such stockholders in the merger consists of (i) shares of the
capital stock of the surviving corporation in the merger, (ii) shares of the
capital stock of any other corporation provided that such stock is listed on a
national securities exchange or quoted on Nasdaq as of the date on which the
merger becomes effective, (iii) cash in lieu of fractional shares or (iv) a
combination of the foregoing.
 
     If World Access elects to pay a portion of the Merger Consideration in
cash, holders of Telco Systems Common Stock who (i) have delivered to Telco
Systems, prior to the vote being taken on the Merger Agreement at the Telco
Systems Special Meeting, their written notice of their intent to demand
appraisal rights if the Merger is effected, and (ii) have not voted in favor of
the Merger Agreement at the Telco Systems Special Meeting will be entitled to
seek appraisal rights under Section 262.
 
     THE FOLLOWING DISCUSSION IS NOT A COMPLETE STATEMENT OF THE LAW PERTAINING
TO APPRAISAL RIGHTS UNDER THE DGCL AND IS QUALIFIED IN ITS ENTIRETY BY THE FULL
TEXT OF SECTION 262 WHICH IS ATTACHED TO THIS JOINT PROXY STATEMENT/PROSPECTUS
AS APPENDIX E. ALL REFERENCES IN SECTION 262 AND IN THIS SUMMARY TO A
"STOCKHOLDER" ARE TO THE RECORD HOLDER OF THE SHARES AS TO WHICH APPRAISAL
RIGHTS ARE ASSERTED. A PERSON HAVING A BENEFICIAL INTEREST IN SHARES OF TELCO
SYSTEMS COMMON STOCK HELD OF
 
                                       60
<PAGE>   72
 
RECORD IN THE NAME OF ANOTHER PERSON, SUCH AS A BROKER OR NOMINEE, MUST ACT
PROMPTLY TO CAUSE THE RECORD HOLDER TO FOLLOW THE STEPS SUMMARIZED BELOW
PROPERLY AND IN A TIMELY MANNER TO PERFECT APPRAISAL RIGHTS.
 
     Under the DGCL, holders of Telco Systems Common Stock who follow the
procedures set forth in Section 262 will be entitled to have their shares of
Telco Systems Common Stock appraised by the Delaware Court of Chancery and to
receive payment of the "fair value" of such shares, exclusive of any element of
value arising from the accomplishment or expectation of the Merger, together
with a fair rate of interest, as determined by such Court.
 
     Under Section 262, where a merger is to be submitted for approval at a
meeting of stockholders, as in the case of the Telco Systems Special Meeting,
the corporation, not less than 20 days prior to the meeting, must notify each of
its stockholders entitled to appraisal rights that such appraisal rights are
available and include in such notice a copy of Section 262. This Joint Proxy
Statement/Prospectus will constitute such notice to the holders of shares of
Telco Systems Common Stock, and the applicable statutory provisions are attached
to this Joint Proxy Statement/Prospectus as Appendix E. Any holder of shares of
Telco Systems Common Stock who wishes to exercise such appraisal rights or who
wishes to preserve such holder's right to do so should review the following
discussion and Appendix E carefully because failure to timely and properly
comply with the procedures specified will result in the loss of appraisal rights
under the DGCL.
 
     A holder of Telco Systems Common Stock wishing to exercise appraisal rights
must deliver to Telco Systems, before the vote on the Merger Agreement at the
Telco Systems Special Meeting, a written demand for appraisal and must not vote
in favor of the Merger Agreement. Because a duly executed proxy which does not
contain voting instructions will, unless revoked, be voted for the Merger
Agreement, a holder of shares of Telco Systems Common Stock who votes by proxy
and who wishes to exercise appraisal rights must either (1) vote against the
Merger Agreement or (2) abstain from voting on the Merger Agreement. A vote
against the Merger Agreement, in person or by proxy, will not in and of itself
constitute a written demand for appraisal satisfying the requirements of Section
262. In addition, a holder of Telco Systems Common Stock wishing to exercise
appraisal rights must hold of record such shares of Telco Systems Common Stock
on the date the written demand for appraisal is made and must continue to hold
such shares until the Effective Time. If any holder of shares of Telco Systems
Common Stock fails to comply with any of these conditions and the Merger becomes
effective, the holder of shares of Telco Systems Common Stock will be entitled
to receive the Merger Consideration.
 
     Only a holder of record of Telco Systems Common Stock is entitled to assert
appraisal rights for the shares of Telco Systems Common Stock registered in that
holder's name. A demand for appraisal should be executed by or on behalf of the
holder of record, fully and correctly, as such holder of record's name appears
on such holder of record's stock certificates, and must state that the
stockholder intends thereby to demand appraisal of such stockholder's shares of
Telco Systems Common Stock in connection with the Merger. If the shares of Telco
Systems Common Stock are owned of record in a fiduciary capacity, such as by a
trustee, guardian or custodian, execution of the demand should be made in that
capacity, and if the shares of Telco Systems Common Stock are owned of record by
more than one person, as in a joint tenancy and tenancy in common, the demand
should be executed by or on behalf of all joint owners. An authorized agent,
including two or more joint owners, may execute a demand for appraisal on behalf
of a holder of record; however, the agent must identify the record owner or
owners and expressly disclose the fact that, in executing the demand, the agent
is agent for such owner or owners. A record holder such as a broker who holds
shares of Telco Systems Common Stock as nominee for several beneficial owners
may exercise appraisal rights with respect to the shares of Telco Systems Common
Stock held for one or more beneficial owners while not exercising such rights
with respect to the shares of Telco Systems Common Stock held for other
beneficial owners. Stockholders who hold their shares of Telco Systems Common
Stock in brokerage accounts or other nominee forms and who wish to exercise
appraisal rights are urged to consult with their brokers to determine the
appropriate procedures for making a demand for appraisal by such a nominee.
 
     All written demands for appraisal pursuant to Section 262 should be sent or
delivered to Telco Systems, Inc. at 63 Nahatan Street, Norwood, Massachusetts
02062, Attention: Chief Financial Officer.
 
                                       61
<PAGE>   73
 
     Within 10 days after the Effective Time, Merger Sub, as the surviving
corporation, must notify each holder of shares of Telco Systems Common Stock who
has complied with Section 262 and has not voted in favor of or consented to the
Merger Agreement of the date that the Merger has become effective. Within 120
days after the Effective Time, but not thereafter, Merger Sub or any holder of
shares of Telco Systems Common Stock who is entitled to appraisal rights under
Section 262 may file a petition in the Delaware Court of Chancery demanding a
determination of the fair value of such holder's shares of Telco Systems Common
Stock. Notwithstanding the foregoing, at any time within 60 days after the
Effective Time, any stockholder has the right to withdraw his demand for
appraisal and to accept the terms offered in respect of the Merger. Merger Sub
is under no obligation to and has no present intention to file such a petition.
Accordingly, it is the obligation of the holders of shares of Telco Systems
Common Stock to initiate all necessary action to perfect their appraisal rights
within the time prescribed in Section 262.
 
     Within 120 days after the Effective Time, any holder of shares of Telco
Systems Common Stock who has complied with the requirements for exercise of
appraisal rights will be entitled, upon written request, to receive from Merger
Sub a statement setting forth the aggregate number of shares of Telco Systems
Common Stock not voted in favor of the Merger and with respect to which demands
for appraisal have been received and the aggregate number of holders of such
shares of Telco Systems Common Stock. Such statement must be mailed to the
stockholders within ten days after a written request therefor has been received
by Merger Sub or within ten days after the expiration of the period for delivery
of demands for appraisal, whichever is later.
 
     If a petition for an appraisal is timely filed by a holder of shares of
Telco Systems Common Stock and a copy thereof is served upon Merger Sub, Merger
Sub will then be obligated within 20 days after such service to file with the
Delaware Register in Chancery a duly verified list containing the names and
addresses of all holders of shares of Telco Systems Common Stock who have
demanded an appraisal of their shares of Telco Systems Common Stock and with
whom agreements as to the value of their shares of Telco Systems Common Stock
have not been reached. After notice to such stockholders as required by the
Court, the Delaware Court of Chancery is empowered to conduct a hearing on such
petition to determine those holders of shares of Telco Systems Common Stock who
have complied with Section 262 and who have become entitled to appraisal rights
thereunder. The Delaware Court of Chancery may require the holders of shares of
Telco Systems Common Stock who demanded payment for their shares of Telco
Systems Common Stock to submit their stock certificates to the Register in
Chancery for notation thereon of the pendency of the appraisal proceeding; and
if any stockholder fails to comply with such direction, the Court of Chancery
may dismiss the proceedings as to such stockholder.
 
     After determining the holders of shares of Telco Systems Common Stock
entitled to appraisal, the Delaware Court of Chancery will appraise the "fair
value" of their shares of Telco Systems Common Stock, exclusive of any element
of value arising from the accomplishment or expectation of the Merger, together
with a fair rate of interest, if any, to be paid upon the amount determined to
be the fair value. Holders of shares of Telco Systems Common Stock considering
seeking appraisal should be aware that the fair value of their shares of Telco
Systems Common Stock as determined by Section 262 could be more than, the same
as or less than the consideration they would receive pursuant to the Merger if
they did not seek appraisal of their shares of Telco Systems Common Stock and
that investment banking opinions as to fairness from a financial point of view
are not necessarily opinions as to fair value under Section 262. The Delaware
Supreme Court has stated that "proof of value by any techniques or methods which
are generally considered acceptable in the financial community and otherwise
admissible in court" should be considered in the appraisal proceedings. In
addition, Delaware courts have decided that the statutory appraisal remedy,
depending on factual circumstances, may or may not be a dissenter's exclusive
remedy. The Court of Chancery will also determine the amount of interest, if
any, to be paid upon the amounts to be received by persons whose shares of Telco
Systems Common Stock have been appraised. The costs of the action may be
determined by the Court and taxed upon the parties as the Court deems equitable.
The Court may also order that all or a portion of the expenses incurred by any
stockholder in connection with an appraisal, including, without limitation,
reasonable attorneys' fees and the fees and expenses of experts utilized in the
appraisal proceeding, be charged pro rata against the value of all the shares of
Telco Systems Common Stock entitled to be appraised.
 
                                       62
<PAGE>   74
 
     Any holder of shares of Telco Systems Common Stock who has duly demanded an
appraisal in compliance with Section 262 will not, after the Effective Time, be
entitled to vote the shares of Telco Systems Common Stock subject to such demand
for any purpose or be entitled to the payment of dividends or other
distributions on those shares of Telco Systems Common Stock (except dividends or
other distributions payable to holders of record of shares of Telco Systems
Common Stock as of a date prior to the Effective Time).
 
     If any stockholder who demands appraisal of such stockholder's Telco
Systems Common Stock under Section 262 fails to perfect, or effectively
withdraws or loses, such stockholder's right to appraisal, as provided in the
DGCL, the shares of Telco Systems Common Stock of such stockholder will be
converted into the right to receive the Merger Consideration pursuant to the
Merger Agreement (without interest). A stockholder will fail to perfect, or
effectively lose or withdraw, such stockholder's right to appraisal if no
petition for appraisal is filed by such holder within 120 days after the
Effective Time, or if the stockholder delivers to Merger Sub a written
withdrawal of his, hers or its demand for appraisal and an acceptance of the
Merger, except that any such attempt to withdraw made more than 60 days after
the Effective Time will require the written approval of Merger Sub and, once a
petition for appraisal is filed, the appraisal proceeding may not be dismissed
as to any holder absent court approval. It is not necessary that each holder of
shares of Telco Systems Common Stock properly demanding appraisal file a
petition for appraisal in the Delaware Court of Chancery. Rather, a single valid
petition suffices for the petitioning and non-petitioning holders of shares of
Telco Systems Common Stock who have properly demanded appraisal.
 
     FAILURE TO FOLLOW THE STEPS REQUIRED BY SECTION 262 OF THE DGCL FOR
PERFECTING APPRAISAL RIGHTS MAY RESULT IN THE LOSS OF SUCH RIGHTS (IN WHICH
EVENT A STOCKHOLDER WILL BE ENTITLED TO RECEIVE THE MERGER CONSIDERATION IN
ACCORDANCE WITH THE MERGER AGREEMENT FOR EACH SHARE OF TELCO SYSTEMS COMMON
STOCK OWNED BY SUCH STOCKHOLDER).
 
     Under the DGCL, holders of World Access Common Stock are not entitled to
appraisal rights in connection with the Merger.
 
EXCHANGE OF SHARES
 
     At or prior to the Effective Time, World Access will appoint, and will
retain an exchange agent (the "Exchange Agent") to effect the exchange of shares
of Telco Systems Common Stock for the Merger Consideration in connection with
the Merger. From time to time after the Effective Time, World Access shall
deposit or cause to be deposited, certificates representing World Access Common
Stock and cash, if any, payable under the Merger Agreement for conversion of
shares of Telco Systems Common Stock in accordance with the Merger Agreement.
 
     Commencing immediately after the Effective Time and until the appointment
of the Exchange Agent is terminated, each holder of a certificate or
certificates theretofore evidencing shares of Telco Systems Common Stock may
surrender the same to the Exchange Agent, and, after the appointment of the
Exchange Agent has been terminated, any such holder may surrender any such
certificate to World Access. Such holder will be entitled upon such surrender to
receive in exchange therefor a certificate or certificates representing the
number of full shares of World Access Common Stock into which the shares of
Telco Systems Common Stock theretofore represented by the certificate or
certificates so surrendered have been converted pursuant to the Merger, together
with a cash payment in lieu of fractional shares, if any, and cash payable in
respect of such shares of Telco Systems Common Stock pursuant to the Merger
Agreement, and such Merger Consideration will be deemed to have been issued at
the Effective Time. Until so surrendered and exchanged, each outstanding
certificate which, prior to the Effective Time, represented issued and
outstanding shares of Telco Systems Common Stock will be deemed for all
corporate purposes of World Access, other than the payment of dividends and
other distributions, if any, to evidence Merger Consideration, into which the
shares of Telco Systems Common Stock theretofore represented thereby have been
converted at the Effective Time.
 
     Until certificates representing shares of Telco Systems Common Stock are
surrendered, no dividend or other distribution, if any, payable to the holders
of record of World Access Common Stock as of any date subsequent to the
Effective Time will be paid to the holder of such certificate. Upon the
surrender of any such
 
                                       63
<PAGE>   75
 
certificate representing shares of Telco Systems Common Stock, however, the
record holder of the certificate or certificates representing shares of World
Access Common Stock issued in exchange therefor will receive from the Exchange
Agent or from World Access, as the case may be, payment of the amount of
dividends and other distributions, if any, which as of any date subsequent to
the Effective Time and until such surrender will have become payable with
respect to such number of shares of World Access Common Stock. No interest will
be payable with respect to the payment of any cash amounts constituting a
portion of the Merger Consideration or such presurrender dividends upon the
surrender of certificates theretofore representing shares of Telco Systems
Common Stock.
 
     No fractional share certificates for World Access Common Stock will be
issued upon the surrender for exchange of certificates evidencing shares of
Telco Systems Common Stock. In lieu thereof, the Exchange Agent or World Access,
as the case may be, will pay each holder of Telco Systems Common Stock an amount
in cash calculated as provided in the Merger Agreement.
 
     Risk of loss and title to certificates representing shares of Telco Systems
Common Stock will pass only upon proper delivery of such certificates to the
Exchange Agent.
 
     At the Effective Time, the stock transfer books of Telco Systems with
respect to shares of Telco Systems Common Stock will be closed, and there will
be no further registration of transfers of shares of Telco Systems Common Stock
thereafter on the records of any such stock transfer books. In the event of a
transfer of ownership of shares of Telco Systems Common Stock that is not
registered in the stock transfer records of Telco Systems, at the Effective
Time, a certificate or certificates representing the number of full shares of
World Access Common Stock into which such shares of Telco Systems Common Stock
have been converted will be issued to the transferee, together with a cash
payment in lieu of fractional shares, if any, and cash, if any, payable under
the Merger Agreement and a cash payment in the amount of any presurrender
dividends, if any, if the certificate or certificates representing such shares
of Telco Systems Common Stock is or are properly surrendered as described above,
accompanied by all documents required to evidence and effect such transfer and
by evidence of payment of any applicable stock transfer tax.

                              THE MERGER AGREEMENT
 
     The following is a description of the material provisions of the Merger
Agreement, as amended by the First Amendment thereto. A copy of the Merger
Agreement, as amended by the First Amendment, is attached hereto as Appendix A
and is incorporated herein by reference. The following summary is qualified in
its entirety by reference to the complete text of the Merger Agreement and the
First Amendment.
 
EFFECTIVE TIME
 
     The Merger will become effective by the filing of a certificate of merger
(the "Certificate of Merger") with the Secretary of State of the State of
Delaware. However, there can be no assurance that the conditions to the Merger
will be satisfied or that the Merger Agreement will not be terminated.
 
CORPORATE MATTERS
 
     At the Effective Time, the certificate of incorporation and by-laws of
Merger Sub, as in effect immediately prior to the Effective Time, will become
the certificate of incorporation and by-laws of the Surviving Corporation, the
directors of Merger Sub immediately prior to the Effective Time will become the
initial directors of the Surviving Corporation and the officers of Telco Systems
immediately prior to the Effective Time will become the initial officers of the
Surviving Corporation.
 
CONVERSION OF SECURITIES
 
     At the Effective Time, by virtue of the Merger and without any action on
the part of World Access, Merger Sub, Telco Systems, the holders of Telco
Systems Common Stock or the holders of common stock, par value $.01 per share,
of Merger Sub ("Merger Sub Common Stock"), (i) each share of Telco Systems
Common Stock issued and outstanding immediately prior to the Effective Time
(together with the Associated Rights) will be converted into the Merger
Consideration as described above under "The Merger -- Conversion of Telco
Systems Common Stock", and (ii) each share of Merger Sub Common Stock issued and
outstanding immediately prior to the Effective Time and all rights in respect
thereof will be converted into and become exchangeable for one newly and validly
issued, fully paid and nonassessable share of common stock of the Surviving
Corporation.
 
OPTIONS TO PURCHASE TELCO SYSTEMS COMMON STOCK
 
     At the Effective Time, each option granted by Telco Systems to purchase
shares of Telco Systems Common Stock (other than options granted to new
employees subsequent to June 4, 1998) which is outstanding and unexercised
immediately prior to the Effective Time, will immediately vest in full and will
be assumed by World Access and converted into an option to purchase shares of
World Access Common Stock in such number and at such exercise price as described
below and otherwise having the same terms and conditions as in effect
immediately prior to the Effective Time (except to the extent that such terms,
conditions and restrictions may be altered in accordance with their terms as a
result of the Merger). The number of shares of World Access Common Stock to be
subject to the new option will be equal to the product of (i) the number of
shares of Telco Systems Common Stock subject to the original option and (ii) the
Exchange Ratio (unless the Exchange Ratio is adjusted to ensure that holders of
Telco Systems Common Stock receive the Minimum Nominal Value in the Merger, in
which event the Exchange Ratio for purposes of this determination shall be equal
to $12.00 divided by the World Access Market Price). The exercise price per
share of World Access Common Stock under the new option will be equal to the
quotient of (i) the exercise price per share of Telco Systems Common Stock under
the original option divided by (ii) the Exchange Ratio (unless the Exchange
Ratio is adjusted to ensure that holders of Telco Systems Common Stock receive
the Minimum Nominal Value in the Merger, in which event the Exchange Ratio for
purposes of this determination shall be equal to $12.00 divided by the World
Access Market Price). Upon each exercise of options by a holder thereof, the
aggregate number of shares of World Access Common Stock deliverable upon such
exercise will be rounded, if necessary, to the nearest whole share and the
aggregate exercise price will be rounded up, if necessary, to the nearest cent.

     The Merger Agreement provides that each of World Access and Telco Systems
must give prompt notice to the other of (i) any notice or other communication
from any person alleging that the consent of such person is or may be required
in connection with the Merger; (ii) any notice or other communication from any
governmental entity in connection with the Merger; (iii) any actions, suits,
claims, investigations or proceedings commenced or, to its knowledge, threatened
against, relating to or involving or otherwise affecting World Access or Telco
Systems that relate to the consummation of the Merger; (iv) the occurrence of a
default or event that, with the giving of notice or lapse of time or both, would
become a default under any material contract of such party; and (v) any change
that could reasonably be expected to have a material adverse effect on Telco
Systems or World Access or to delay or impede the ability of either Telco
Systems or World Access to perform its obligations pursuant to the Merger
Agreement and to effect the consummation of the Merger.
 
ACCESS TO INFORMATION; CONFIDENTIALITY
 
     The Merger Agreement provides that, from the date of the Merger Agreement
to the Effective Time, each of World Access and Telco Systems must (i) provide
to the other access at reasonable times to its officers, employees, agents,
properties, offices and other facilities and to the books and records thereof;
and (ii) furnish promptly such information concerning its and its subsidiaries'
business, properties, contracts, assets, liabilities and personnel as the other
party may reasonably request. In addition, the obligations of World Access and
Telco Systems under the Confidentiality Agreement remain in effect.
 
NO SOLICITATION OF TRANSACTIONS
 
     The Merger Agreement provides that Telco Systems may not, directly or
indirectly, solicit, initiate or knowingly encourage (including by way of
furnishing nonpublic information), or take any other action knowingly to
facilitate, any inquiries or the making of any proposal or offer (including,
without limitation, any proposal or offer to its stockholders) that constitutes,
or may reasonably be expected to lead to, any Competing Transaction (as
described below), or enter into or maintain or continue discussions or negotiate
with any person in furtherance of such inquiries or to obtain a Competing
Transaction, or agree to or endorse any Competing Transaction, or authorize or
permit any of Telco Systems's officers, directors or employees, or any
 
                                       67
<PAGE>   79
 
investment banker, financial advisor, attorney, accountant or other
representative retained by Telco Systems, to take any such action. However, the
Merger Agreement provides that the board of directors of Telco Systems may (i)
comply with Rule 14e-2 promulgated under the Exchange Act with regard to a
tender or exchange offer; (ii) consider and negotiate an unsolicited bona fide
written acquisition proposal which (A) was not received in violation of the
Merger Agreement, (B) if executed or consummated would be a Competing
Transaction, (C) is not subject to financing or financing is, in the good faith
judgment of the board of directors of Telco Systems after consultation with its
financial advisors, highly likely of being obtained if the board determines in
good faith, after receiving the advice of outside counsel, that it is highly
probable that failing to do so would violate its fiduciary duties; and (iii)
approve and recommend to Telco Systems' stockholders an unsolicited bona fide
written acquisition proposal which (A) was not received in violation of the
Merger Agreement, (B) if executed or consummated would be a Competing
Transaction, (C) is not subject to financing or financing is, in the good faith
judgment of the board after consultation with its financial advisors, highly
likely of being obtained, and (D) the board determines in good faith, after
advice from its financial advisor to such effect, would result in a transaction
more favorable to Telco Systems' stockholders than the Merger (any such
proposal, a "Superior Proposal") if the board determines in good faith, after
receiving the advice of outside counsel, that it is highly probable that failing
to do so would violate its fiduciary duties. The Merger Agreement requires that
Telco Systems must notify World Access and Merger Sub promptly if any proposal
or offer, or any inquiry or contact with any person with respect thereto,
regarding such an acquisition proposal or a Competing Transaction is made.
 
     For purposes of the Merger Agreement, "Competing Transaction" means, with
respect to Telco Systems or any of its subsidiaries whose business constitutes
30% or more of the net revenues,net income or assets of Telco Systems and its
subsidiaries taken as a whole, (i) any merger, consolidation, share exchange,
business combination or other similar transaction; (ii) any sale, lease,
exchange, mortgage, pledge, transfer or other disposition of 15% or more of the
assets of Telco Systems, in a single transaction or series of transactions;
(iii) any tender offer or exchange offer for 15% or more of the outstanding
voting securities of Telco Systems or the filing of a registration statement
under the Securities Act in connection therewith.
 
PLAN OF REORGANIZATION
 
     The Merger is intended to constitute a tax-free reorganization within the
meaning of the income tax regulations promulgated under the Code. Pursuant to
the Merger Agreement, Telco Systems and World Access have agreed that, from and
after the date of the Merger Agreement, they will use all reasonable efforts to
cause the Merger to qualify, and will not take any actions or cause any actions
to be taken which could reasonably be expected to prevent the Merger from
qualifying, as a tax-free reorganization under the Code.
 
FURTHER ACTION; CONSENTS; FILINGS
 
     The Merger Agreement provides that each of Telco Systems and World Access
must use all reasonable efforts to (i) take, or cause to be taken, all
appropriate action, and do, or cause to be done, all things necessary, proper or
advisable under applicable law or otherwise to consummate and make effective the
Merger, (ii) obtain from governmental entities any consents, licenses, permits,
waivers, approvals, authorizations or orders required to be obtained or made by
World Access, Old World Access, Merger Sub, Telco Systems or the Surviving
Corporation in connection with the authorization, execution and delivery of the
Merger Agreement and the consummation of the Merger and (iii) make all necessary
filings, and thereafter make any other required or appropriate submissions, with
respect to the Merger Agreement and the Merger required under the rules and
regulations of Nasdaq, the Securities Act, the Exchange Act and any other
applicable federal or state securities laws and any other applicable law. Telco
Systems and World Access are also required to promptly give any notices
regarding the Merger, the Merger Agreement or the transactions contemplated
thereby to third parties required under applicable law or by any contract,
license, lease or other agreement to which it is bound, and to use all
reasonable efforts to obtain any third party consents required under any such
contract, license, lease or other agreement in connection with the consummation
of the Merger or the other transactions contemplated by the Merger Agreement.

                        THE STOCKHOLDERS PROXY AGREEMENT
 
     Contemporaneous with the execution of the Merger Agreement and as a
condition to the willingness of World Access to enter into the Merger Agreement,

Flaschen, Edward J. Fontenot, Sheldon Horing, William B. Smith, William J.
Stuart, Richard J. Nardone, Philip B. Wilson, David A. LeBeau, LeRoy C. Kopp,

for itself and as attorney-in-fact for certain of its clients, (each a
"Stockholder" and, together, the "Stockholders"), collectively owners of
approximately 8% of the outstanding shares of Telco Systems Common Stock.
Pursuant to the Telco Systems Proxy Agreement, each Stockholder agreed to vote,
and granted to World Access an irrevocable proxy to vote, all voting securities
of Telco Systems held by such Stockholder in favor of approval of the Merger
Agreement and the Merger.
 
     The following is a description of the material provisions of the Telco
Systems Proxy Agreement, a copy of which is attached as Appendix D to this Joint
Proxy Statement/Prospectus. The following summary is qualified in its entirety
by reference to the complete text of the Telco Systems Proxy Agreement.
 
     The Telco Systems Proxy Agreement provides that, during the term thereof,
each Stockholder will not (i) sell, pledge or otherwise dispose of any of its
shares of Telco Systems Common Stock, (ii) deposit its shares of Telco Systems
Common Stock into a voting trust or enter into a voting agreement with respect

BUSINESS
 
     Overview.  World Access develops, manufactures and markets wireline and
wireless switching, transport and access products for the global
telecommunications markets. World Access products allow telecommunications
service providers to build and upgrade their central office and outside plant
networks in order to provide a wide array of voice, data and video services to
their business and residential customers. World Access offers digital switches,
billing and network telemanagement systems, cellular base stations, fixed
wireless local loop systems, intelligent multiplexers, microwave and
millimeterwave radio systems and other telecommunications network products. The
products offered by World Access include those manufactured by World Access, as
well as those manufactured by other telecommunications equipment companies. To
support and complement its product sales, World Access also provides its
customers with a broad range of design, engineering, manufacturing, testing,
installation, repair and other value-added services.
 
     The global telecommunications industry has undergone significant
transformation and growth in recent years due to domestic deregulation,
technological innovation and growth in international markets. In addition,
business and residential demand for voice, data and video telecommunications
services has increased the need for additional systems capacity and network
bandwidth to accommodate the provision of such services by telecommunications
providers. World Access believes that these market forces will intensify in the
foreseeable future and that an increased number of telecommunications service
providers, the availability of new services and strong international demand for
the deployment of basic telephone service will provide World Access with
extensive opportunities to sell its wireline and wireless switching, transport
and access products in the United States and in international markets.
 
     Products and Services.  World Access offers wireline and wireless
switching, transport and access products for the global telecommunications
marketplace. These products allow telecommunications service providers to build
and upgrade their networks to provide a wide range of voice, data and video
services to business and residential customers. To date, a significant portion
of the products sold by World Access has been Northern Telecom switching
products and reengineered cellular base stations and related mobile network
equipment. Through acquisitions, technology license agreements and internal
development, World Access expects to manufacture an increasing proportion of its
products in the future.
 
     Switching Products.  World Access markets digital telephone switching
products that are used for local, tandem, toll and cellular applications. The
switches offered by World Access have line capacities ranging from 100 to
120,000 subscribers and 30 to 60,000 inter-exchange trunks. Switching products
historically offered by World Access have been primarily developed and
manufactured by other telecommunications equipment companies, including Northern
Telecom and Lucent Technologies. These products include complete switching
systems as well as add-on frames, line cards and modified circuit boards for
either newly constructed networks or upgrades to existing networks.
 
     Pursuant to a long-term technology license agreement, World Access
manufactures and markets the Compact Digital Exchange Switch ("CDX"), a
microprocessor-based, modular, digital central office switch. The CDX utilizes
extensive large scale integrated circuit technology to provide advanced
telephony services such as call waiting, call forwarding and conference calling,
and requires reduced power and floorspace compared with alternative products.
The current switch serves applications up to 5,000 subscriber lines and is
designed to be expandable to over 60,000 lines through future software
enhancements. The CDX is targeted for use in the international marketplace due
to its compatibility with international standards, "plug and play" installation
features and tolerance of a wide range of environmental conditions.
 
     With World Access' acquisition of a majority stake in NACT in the first
quarter of 1998 and its acquisition of the remainder of NACT in October 1998 in
connection with the Holding Company Reorganization, World Access has
significantly expanded its offering of proprietary, advanced technology
switching products and software applications.
 
     NACT's STX Switching System ("STX") consists of an integrated application
switching platform and a suite of applications software. World Access sells an
optional companion Master Control Unit ("MCU") to
 
                                       73
<PAGE>   85
 
integrate and service multiple STXs and to add redundancy to the network. World
Access believes that the STX offers value added features and capacity at price
points typically below those offered by its competitors. The STX hardware
platform can operate on a standalone basis with a port capacity of 1,344. An
optional MCU can link up to three STXs, which can be served by a common database
for a total system capacity of 4,032 ports. The STX is also designed to work
seamlessly with NACT's NTS 1000 billing system.
 
     NACT's suite of STX applications software consists of over one million
lines of code. This software supports major application features that are fully
integrated and interoperable. The major applications features include: equal
access calling (1+), automated operator (0+), live operator service provider
support (0-), real-time validation of credit card and billing numbers, prepaid
debit cards, prepaid cellular, international call back, phone centers, real-time
rating, fraud minimization, external computer application programming
interfaces, call reorigination, and integrated audio with twenty two languages.
Interoperability enables several applications packages to be used in conjunction
with each other. Almost all features are implemented in software, allowing
unlimited capability for enhancement and customization.
 
     The NTS 1000 Billing System ("NTS 1000") is a call rating, accounting,
switch management, invoicing and traffic engineering system designed to process
the day-to-day operations of a small-to-medium sized long distance company. The
NTS 1000 can collect calls from most major switching platforms, including the
STX, and can rate all types of call traffic and, using a sophisticated rating
engine, provide the owner with a highly flexible and completely customized
rating capability. The accounting system handles all of the required information
for managing a long distance customer base including configuration of
authorization codes, accounts receivable, and management of delinquent accounts.
A major feature of the NTS 1000 is its switch management capability. When
coupled with the STX, information that has been entered into the NTS 1000 can be
electronically transferred into the STX, thereby minimizing data entry needs.
The NTS 1000 also has complete international call back/reorigination and prepaid
debit card management support, as well as a complete invoicing package that
supports multiple invoice styles and options for summary reports. It has a
sophisticated traffic engineering reporting package that provides the ability to
generate over 20 types of reports with a user specified beginning and ending
time range.
 
     Current users of World Access' switching products are primarily local
exchange carriers, inter-exchange carriers, competitive access providers,
private network operators and other telecommunications service providers. World
Access intends to expand its United States customer base for switching products
and to actively market the CDX to public and private network providers in Latin
America and other international markets.
 
     Transport Products.  World Access develops, manufactures and markets a
variety of wireline and wireless transport products, which are used for
high-capacity connectivity between points within a communications network. These
products are primarily digital and provide for the movement of any combination
of voice, data and video traffic across wireline or wireless media. World
Access' transport products include intelligent multiplexers (devices which
combine or aggregate several channels or linkages carrying voice or data signals
into a higher speed link), protection switching equipment (which protect voice
and data links against failure by rerouting circuits to maintain continuity),
mini-repeater housings (enclosures used to protect electronic repeaters from the
elements), asynchronous and fractional data cards, microwave and millimeterwave
radio equipment and sophisticated high speed modems used to carry voice and data
in wireline or wireless networks.
 
     World Access' T-1 multiplexers include features such as local and remote
loopbacks, built-in bit error rate detection, line code selection and built-in
performance monitoring. World Access has developed and is currently testing an
E-1 multiplexer designed for the international markets. This new proprietary
product can combine 60 channels of voice and data into a single E-1 circuit.
 
     With World Access' acquisition of ATI in the first quarter of 1998, World
Access has significantly expanded its offering of proprietary, advanced
technology wireless voice, data and/or video transport products.
 
     ATI develops, manufacturers and markets a complete family of high
performance, technologically advanced digital radios for point-to-point
transmission of data and voice for short and long haul applications. The
majority of ATI's historical sales have been to customers operating outside the
United States. ATI's
 
                                       74
<PAGE>   86
 
product lines are offered in a wide range of data rates and frequency bands,
including 1.5 GHz to 38 GHz and DS1/E1 to DS3/E3.
 
     Current users of World Access' transport products are primarily an RBOC and
private network users. World Access intends to expand its current customer base
for transport products by broadening the features of its current products,
increasing its marketing efforts in the United States and developing new
products for the emerging international markets.
 
     Access Products.  World Access offers access products for the local loop
(i.e., that portion of the public telecommunications network which extends from
the service provider's switch to the individual home or business end-user). With
the acquisition of CIS in the first quarter of 1997, World Access also offers
its customers cellular base stations and related mobile network equipment.
Although substantially all of the equipment sold by CIS is manufactured by other
telecommunications equipment companies, CIS provides a full range of highly
technical, value-added services such as deinstallation, system design, equipment
tuning and installation.
 
     In the first quarter of 1997, World Access released a new internally
developed access product, the WX-5501 Remote POTS/Remote Universal Voice Grade
("RPOT/RUVG") line card. The WX-5501 is compatible with the Lucent Technologies
SLC(R) Series 5 subscriber loop carrier system, which is widely deployed in
telephone networks across the United States.
 
     In the second quarter of 1997, World Access introduced its Wireless Local
Loop 2000 ("WLL-2000"), a fixed wireless point-to-multipoint system offering
toll quality telephone service to subscribers in urban and suburban areas and
remote communities. To take advantage of existing market opportunities, World
Access reached an agreement in 1997 with another telecommunications equipment
company to private label its point-to-multipoint radio system and exclusively
market it within certain Latin American countries. The current WLL-2000
integrates World Access's CDX and the private label radio. The integrated switch
provides customers with the ability to switch local calls at the WLL-2000 base
station, thus providing superior service and reducing expensive back-haul costs
to a central office. The CDX and WLL-2000 for the first time provide World
Access with an integrated family of proprietary switching and wireless access
products for the international market.
 
     In 1997, World Access also executed a technology licensing agreement that
grants World Access the perpetual right to incorporate spread spectrum
CDMA-based wireless technology into World Access' products sold throughout the
world. Under the terms of the agreement, World Access also has the rights to use
the technology covered by seven patents, all of which address digital data
signals and wireless communication systems. World Access currently intends to
use this technology as the platform for several new products.
 
     As a result of the acquisition of Sunrise in 1996, World Access
manufactures and markets a digital loop carrier (which permits network operators
to provide more reliable, basic and enhanced services at a lower cost) and DS-3
telemetry equipment (used primarily by the military for range communications
applications to multiplex telemetry, digital video, T-1, LAN, WAN and other
signals into a DS-3 signal transmitting at 45 megabits per second). World Access
has recently developed and is currently testing a commercial version of its DS-3
product, the Ultra-45. This advanced multiplexer provides a solution for current
and future telecommunications applications requiring simultaneous delivery of
high speed data, video, LAN, voice and telemetry services.
 
     Current users of World Access' access products are primarily local exchange
carriers, inter-exchange carriers, competitive access providers, cable
television companies and the United States military. World Access intends to
expand its current customer base for access products by broadening the features
of its current products, increasing its marketing efforts in the United States
and developing new products for emerging international markets.
 
     Related Services.  World Access offers a full range of complementary
design, manufacturing, installation, testing and repair services. World Access
also offers its customers ongoing systems maintenance and monitoring services,
including asset management services, which allow customers to reduce their
investment in spare and surplus plug-in circuit boards by relying on World
Access' inventories and management
 
                                       75
<PAGE>   87
 
information systems. By providing these services, World Access believes it is
better able to offer its customers more comprehensive telecommunications
solutions.
 
     World Access repairs a broad range of switching and transmission plug-in
circuit boards originally manufactured by other telecommunications equipment
companies. World Access' wireless equipment repair business consists principally
of the repair and upgrade of amplitude modulation equipment typically used by
cable television companies. World Access' engineers also provide customers with
a full range of support services for wireless transmission equipment, including
system design, site survey, path calculations, installation and maintenance.
 
     In the third quarter of 1997, World Access completed its acquisition of
Galaxy, a provider of system design, implementation, optimization and other
value-added radio engineering and consulting services to PCS, cellular and other
wireless telecommunications service companies. The background and experience of
Galaxy's management and staff of RF engineers will be utilized to support World
Access' customers as they build new, or upgrade existing, telecommunications
networks throughout the world.
 
     Other Products and Services.  World Access' other products and services
include the refurbishment and upgrade of AT&T pay telephones to like-new
condition and the sale of related pay telephone products, such as stainless
steel custom logo vault doors, handsets and dial assemblies. To date,
substantially all of these refurbishment services and product sales have been
provided to four RBOCs.
 
     Sales and Marketing.  As of October 31, 1998, World Access' domestic sales
and marketing group consisted of 52 sales professionals and assistants who are
divided into individual sales and marketing teams for each of World Access'
product lines and related services. Each team is responsible for obtaining a
thorough technical knowledge of its products or services, soliciting new
customers and maintaining relationships with existing customers. Each team is
supervised at the corporate level by World Access' Executive Vice President of
Business Development, who coordinates the sales and marketing of multi-product
line sales and is responsible for advertising, trade show appearances and other
company-wide marketing efforts. In connection with the acquisitions completed
during the last few years, World Access has acquired product sales professionals
who have brought technical product knowledge and long-term customer
relationships to World Access.
 
     In 1996, World Access formed a dedicated international sales and marketing
group to pursue the sale of all of World Access' products and services outside
of the United States. As of October 31, 1998, this group consisted of 8 sales
professionals and assistants. World Access has an established network of
independent agents and representatives covering the Caribbean Basin and Latin
America. These agents and representatives, whose compensation consists primarily
of commissions based on sales, actively promote and market World Access'
products and services and receive bid tenders issued within their territory.
 
     During 1997, World Access' international sales increased to approximately
11.3% of total company sales as compared to 2.0% in 1996. World Access intends
to continue to focus significant sales and marketing efforts on emerging
international markets.
 
     Customers.  World Access sells its products and services to over 200
telecommunication service providers, including the RBOCs, other local exchange
carriers, inter-exchange carriers, wireless service
 
                                       76

     For the year ended December 31, 1997, no customer of World Access
individually accounted for 10.0% of World Access' total sales. World Access' top
10 customers accounted for 44.2% of total sales. For the year ended December 31,
1996, Cable & Wireless accounted for 10.9% of World Access' total sales, and
World Access' top 10 customers accounted for 54.2% of total sales. World Access'
customers typically are not obligated contractually to purchase any quantity of
products or services in any particular period.
 
     Manufacturing, Assembly and Test.  World Access provides a broad range of
electronic manufacturing, assembly and test services to support its product
sales. The majority of these support services have been historically performed
at World Access' Orlando, Florida facility, where state-of-the-art manufacturing
and test equipment is maintained. Historically, this equipment has been used
primarily to perform contract manufacturing services for third parties,
primarily to large technology companies that require a high level of
professional materials management, quality "turn-key" manufacturing and complete
electronic and functional product testing. During 1997, World Access began
utilizing its manufacturing capacity to build new company products as well as
servicing third party contract manufacturing customers.
 
     As a result of the recent growth in sales of World Access' internally
developed products, including additional products from the acquisitions of NACT
and ATI, World Access opened a new manufacturing facility in Alpharetta,
Georgia. The Orlando facility was closed during the second quarter of 1998 as
World Access exited from the third party contract manufacturing business.
 
     World Access' new Alpharetta manufacturing operation has state-of-the-art
surface mount manufacturing and automated testing equipment. This equipment
includes a surface mount assembly line, including advanced "pick-and-place"
equipment and a 3-D vision screen printer. This equipment is currently operating
at less than 50% of the line's capacity. World Access has also recently acquired
new board test systems that provide for high performance, automated testing of
analog, digital, mixed signal and memory devices resident on printed circuit
boards. When combined with World Access' existing testing equipment, the new
equipment gives World Access an extensive software library and technical
capacity to test integrated circuits, capacitors, resistors and related
electronic components, and ensures the quality of electronic products
manufactured.
 
     In addition to the relocation of its manufacturing facility, World Access
also took additional actions during the first half of 1998 to streamline
operations, improve efficiency and better service its customers. In the second
quarter of 1998, four facilities in Lakeland, Florida and the existing circuit
board repair operations in Orlando, Florida moved to a new facility in Orlando.
World Access' AIT operations, which include the testing of Northern Telecom
switching equipment and verification of the configuration and integration of
add-on frames and custom systems, and World Access' circuit board repair
business is conducted in the new Orlando facility under one management team.
 
     At ATI's facility in Wilmington, Massachusetts, World Access utilizes
sophisticated RF test and tuning equipment to manufacture and service it
microwave radio systems. In the second quarter of 1998, World Access relocated
its Westec operations from Scottsdale, Arizona to Wilmington to improve
operating efficiencies and reduce administrative costs.
 
                                       77
<PAGE>   89
 
     NACT currently conducts its manufacturing operations consisting primarily
of final assembly, test and quality control of subassemblies and completed
systems, in its new manufacturing facility in Provo, Utah.
 
     World Access has an experienced Director of Quality who, along with a staff
of quality assurance professionals, oversees the quality of World Access'
products and services. World Access' Orlando and Wilmington operations are ISO
9002 and ISO 9001 certified, respectively. World Access expects its Alpharetta
and Provo operations to become ISO certified in the first quarter of 1999. ISO
9000 is an international quality certification process, developed in the
European Common Market and adopted in the United States as the method by which
companies can demonstrate the functionality of their quality control system.
 
     In connection with its manufacturing and test services, World Access
generally provides warranties on its products and services ranging from three
months to five years. A one to two year warranty is typically provided on
switching, transport and access products.
 
     World Access believes that it currently has the equipment, personnel and
experience necessary to efficiently manufacture high quality telecommunications
products in-house. This should assist World Access in controlling the costs,
quality and delivery of its products and allow World Access to bring new
products to market on a timely basis.
 
     Suppliers.  Products manufactured by World Access typically require the
procurement of printed circuit boards, electronic components, cable assemblies,
fabricated metal, plastic parts and other materials, of which electronic
components are the most costly. World Access purchases electronic components
from numerous sources, including original manufacturers and parts distributors.
 
     World Access purchases substantially all of its components and other parts
from suppliers on a purchase order basis and does not maintain long-term supply
arrangements. Most of the components used in World Access' products and related
services are available from multiple sources. However, several components,
primarily custom hybrid integrated circuits, are currently obtained from a
single source. To date, World Access has been able to obtain adequate supplies
of these components. World Access' inability in the future to obtain sufficient
quantities of limited-source components, or to develop alternative sources
therefor, could result in delays in product delivery and increased component
cost, either of which could have a material adverse effect on World Access'
business, financial condition and results of operations.
 
     Although World Access manufactures its own switching products, a
significant portion of the switching products sold to date by World Access has
been new or used Northern Telecom switching systems, add-on frames and circuit
boards, and reengineered mobile network equipment. The major sources for such
products are deinstallations by primary users, asset recovery operations of
telephone companies, auctions by Northern Telecom and other original equipment
manufacturers, repossessions by leasing companies and formal distribution or
consignment agreements. World Access currently has formal consignment agreements
with Ameritech, SNET and Century Telephone, pursuant to which World Access
inventories Northern Telecom, Lucent Technologies and other circuit boards for
resale by World Access.
 
     Engineering and Development.  Historically, World Access' engineering,
development and technical support efforts have focused on the repair of
switching, transport and access products and on electronic manufacturing
processes. World Access has significant experience in developing automated test
systems, diagnostic programs and repair procedures for electronic circuitry
typically found within telecommunications switching equipment. World Access'
engineers have also used their expertise and experience to create new revenue
sources for World Access by developing upgrades and enhancements to existing
products, including those developed and manufactured by other telecommunications
equipment companies.
 
     World Access' engineering efforts have become more focused on developing
new switching, transport and access products and enhancing the features and
capabilities of current products. The acquisitions of NACT and ATI have enhanced
World Access' engineering and development capabilities of switching and
transport products with the addition of approximately 50 development engineers.
World Access' engineers have significant experience in switching systems
configurations, transmission and access applications and wireless technology
such as spread spectrum CDMA, radio path calculations, field performance
measurement and
                                       78
<PAGE>   90
 
frequency licensing. World Access expects that, as it continues to manufacture
and sell more sophisticated telecommunications equipment, it will continue to
make further significant investments in research and product development.
 
     As of October 31, 1998, World Access' engineering and development group
consisted of 130 persons, including 48 RF engineers added through the Galaxy
acquisition, 70 in product development, and 12 in repair service development,
systems integration and manufacturing process and operations support. These
employees are organized into teams corresponding to World Access' product lines,
and each team is responsible for providing technical support to World Access'
customers and for developing and enhancing products. World Access' internal
engineering resources permit World Access to continually reduce the production
cost and improve the functionality of its products.
 
     Competition.  The segments of the telecommunications industry in which
World Access operates are intensely competitive. World Access' ability to
compete is dependent upon several factors, including price, quality, product
features and timeliness of delivery. Many of World Access' competitors have
significantly more extensive engineering, manufacturing, marketing, financial
and technical resources than World Access. In addition, World Access currently
competes with several of its major suppliers, including Northern Telecom, with
respect to the sale of certain of its products, which may adversely affect its
ability to continue to obtain such products from these suppliers in the future.
 
     In the sale of switching, transport and access products, World Access
competes with companies such as Northern Telecom and Lucent Technologies. World
Access believes it competes favorably against these companies by providing high
quality products, comprehensive support services, competitive prices and
shortened product delivery times. As World Access increases its international
sales efforts, it also expects to compete with other established
telecommunications equipment companies such as Ericsson, Fujitsu, Siemens and
Alcatel Network Systems.
 
     Employees.  As of October 31, 1998, World Access had 537 full-time
employees, including 130 in engineering and development, 46 in technical service
and support, 60 in sales and marketing, 137 in manufacturing, warehousing and
quality assurance, 80 in repair and refurbishment and 84 in general management,
finance, administration and other support services. From time to time, World
Access also uses part-time employees in its manufacturing operations to
accommodate changes in production levels. None of World Access' employees is
represented by any collective bargaining agreements, and World Access has never
experienced a work stoppage. World Access considers its employee relations to be
good.
 
PROPERTIES
 
     World Access' executive offices are located in Atlanta, Georgia, where it
occupies approximately 4,000 square feet under a lease expiring in October 2000.
World Access leases certain office, manufacturing and warehouse facilities under
operating leases which expire at various dates during the next five years. The
following provides a summary of the significant operating facilities currently

LEGAL PROCEEDINGS
 
     From time to time, World Access is involved in various legal proceedings
relating to claims arising in the ordinary course of its business. Neither World
Access nor any of its subsidiaries is party to any legal proceeding, the outcome
of which, individually or in the aggregate, is expected to have a material
adverse effect on World Access' financial condition or results of operations.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS OF WORLD ACCESS
 
Overview
 
     World Access develops, manufactures and markets wireline and wireless
switching, transport and access products for the global telecommunications
markets. The products offered by World Access include those manufactured by
World Access as well as those manufactured by other telecommunications equipment
manufacturers. To support and complement its product sales, World Access also
provides its customers with a broad range of design, engineering, manufacturing,
testing, installation, repair and other value-added services.
 
     During 1995 and 1996, World Access completed strategic and financial
restructuring programs to strengthen its management team, reposition World
Access as a provider of telecommunications products, improve its financial
condition, reduce its operating costs and position World Access for future
growth. These programs were undertaken following the significant losses incurred
by World Access in the early 1990s, primarily due to a discontinued smart pay
telephone business, and to take advantage of the significant growth
opportunities within World Access' existing customer base and related markets.
In November 1994, World Access began to rebuild its management team and change
its strategic focus. World Access strengthened its management team by appointing
a new Chief Executive Officer and by recruiting and hiring a new President and
Chief Operating Officer, Executive Vice President of Business Development and
experienced product development and manufacturing professionals. These
individuals, together with other key managers recruited into World Access, have
brought significant experience in manufacturing and marketing telecommunications
equipment to World Access.
 
     World Access acquired five businesses during 1995 to 1997 in an effort to
broaden its line of switching, transport and access products, enhance its
product development capabilities and strengthen its technical base. Effective
May 1995, World Access acquired AIT, a full service provider of Northern Telecom
switching systems, add-on frames and related circuit boards; effective October
1995, World Access acquired Westec, a provider of wireless products and services
primarily to the cable television industry; effective January 1996, World Access
acquired Sunrise, a developer and manufacturer of intelligent transport and
access products; effective January 1997, World Access acquired CIS, a provider
of mobile network equipment and related design, installation and technical
support services to cellular, PCS and other wireless service providers; and
effective August 1997, World Access acquired Galaxy, a RF engineering firm that
provides system design, implementation, optimization and other value-added radio
engineering and consulting services to the wireless service markets. The markets
served by CIS and Galaxy complement World Access' traditional telephone service
provider and private network operator markets.
 
     In the first quarter of 1998, World Access acquired ATI, a manufacturer of
digital point-to-point microwave radio systems for short and long haul
applications and a majority stake in NACT, a provider of advanced
telecommunications switching platforms with integrated applications software. In
May 1998, World Access signed definitive agreements to acquire Resurgens, a
facilities-based provider of international network access, commonly referred to
in the industry as carriers' carrier. In June 1998, World Access signed a
definitive agreement to acquire Telco Systems, a manufacturer of asynchronous
fiber optic systems and intelligent channel banks for the integrated access,
high capacity multiplexer and Frame Relay/ATM access markets. These acquisitions
have positioned World Access to offer its customers a complete
telecommunications network solution, including proprietary equipment, planning
and engineering services and access to international long distance.
 
     World Access realized significant improvements in its sales and operating
results since 1994 as a result of the acquisitions and internal growth
initiatives. World Access' total sales increased by 82.3% in 1997, 69.2% in 1996
and 97.2% in 1995. Total sales for the first six months of 1998 increased by
41.5% over the last six months of 1997. As World Access increased its product
sales from 18.2% of total sales in 1994 to 79.0% of total sales in the first six
months of 1998, its gross profit margin before special charges increased from
12.9% in 1994 to 21.1% in 1995, 29.4% in 1996, 34.6% in 1997 and 44.1% in the
first six months of 1998. As a percentage of total sales, World Access'
operating income (loss) before special charges increased from (8.5%) in 1994 to
5.0% in 1995, 14.4% in 1996, 21.0% in 1997 and 27.6% in the first six months of
1998. World Access
 
                                       81

will continue to seek further improvements in gross profit margin over time as
product offerings include more internally developed, acquired and licensed
products containing proprietary technology.
 
     Although World Access has aggressively pursued acquisitions in recent
years, approximately 50% of World Access' total sales growth since 1994 has come
from internal growth initiatives. World Access has had considerable success in
growing businesses subsequent to their acquisition, due in part to World Access'
ability to provide working capital, an extensive base of telecommunications
customers and a broad range of support services.
 
     Since January 1, 1995, World Access has significantly strengthened its
balance sheet through improved operating results, a $115.0 million sale of
convertible subordinated notes, a $26.2 million secondary public equity
offering, stock warrant and option exercises, and a five-year $10.0 million
credit facility. World Access has used this capital for acquisitions and to
support the working capital requirements associated with World Access' growth.
World Access' working capital and stockholders' equity have increased from $2.3
million and $1.2 million, respectively, at December 31, 1994 to $116.1 million
and $98.6 million, respectively, at June 30, 1998.

Year Ended December 31, 1997 Compared to Year Ended December 31, 1996
 
     Sales.  Total sales increased $42.0 million, or 82.3%, to $93.0 million in
1997 from $51.0 million in 1996. Product sales increased to 76.8% of total sales
in 1997 from 67.5% in 1996.
 
                                       82
<PAGE>   94
 
     Product sales increased $37.0 million, or 107.5%, to $71.4 million in 1997
from $34.4 million in 1996. The increase related to $26.2 million of mobile
network equipment sold by CIS, which was acquired effective January 1, 1997, an
additional $6.4 million of switching products sold by AIT and approximately $6.9
million in sales of World Access' new international products, the CDX and
WLL-2000. Product sales for 1996 included approximately $4.8 million in one-time
sales of a distributed product.
 
     Service revenues increased $5.0 million, or 30.2%, to $21.6 million in 1997
from $16.6 million in 1996. The increase related to $2.0 million of engineering
services performed by Galaxy, which was acquired effective July 1, 1997, and an
additional $5.2 million in pay telephone refurbishment revenues. This increase
was partially offset by a decline in electronic manufacturing revenues resulting
from a strategic decision to begin utilizing World Access' manufacturing
capacity for new products rather than servicing external contract manufacturing
customers.
 
     Gross Profit.  Gross profit increased $17.1 million, or 114.3%, to $32.1
million in 1997 from $15.0 million in 1996. Gross profit margin increased to
34.6% in 1997 from 29.4% in 1996. The improved performance resulted from
economies of scale associated with the 82.3% increase in total sales and the
change in sales mix to products, which generally carry a higher gross profit
margin than service revenues.
 
     Gross profit margin on products sold increased to 38.6% in 1997 from 37.6%
in 1996. The improved margins related to the $26.2 million of CIS sales and
sales of the CDX, all of which generally carry margins in excess of 40.0%. World
Access' switching products experienced declines in gross margin during 1997
primarily related to margin pressure on sales of Northern Telecom add-on frames
and related circuit boards.
 
     Gross profit margin on service revenues increased to 21.2% in 1997 from
12.5% in 1996. The improvement was due to the addition of Galaxy consulting
revenues and improved margins on pay telephone refurbishment revenues.
 
     Engineering and Development.  Engineering and development expenses
increased $970,000, or 108.7%, to $1.9 million in 1997 from $892,000 in 1996.
The increase in expenses was attributable to the formation of a corporate
product development group during the third quarter of 1996 and the continued
expansion of the development group during 1997. Engineering and development
expenses increased to 2.0% of total sales in 1997 from 1.7% of total sales in
1996.
 
     Selling, General and Administrative Expenses.  Selling, general and
administrative expenses increased $2.8 million, or 44.9%, to $9.0 million in
1997 from $6.2 million in 1996. The increase related primarily to expenses
associated with the operations of CIS and Galaxy, which were acquired effective
January 1, 1997 and July 1, 1997, respectively, and World Access' establishment
of a dedicated international sales and marketing group and corporate business
development function in March 1996. In addition, World Access recorded
approximately $960,000 of incentive compensation expense in 1997 as compared to
a provision of approximately $300,000 in 1996. As a percentage of total sales,
selling, general and administrative expenses decreased to 9.7% in 1997 from
12.2% in 1996.
 
     Amortization of Goodwill.  Amortization of goodwill increased $1.2 million
to $1.8 million in 1997 from $534,000 in 1996, primarily as a result of goodwill
recorded in connection with the AIT, CIS and Galaxy acquisitions.
 
     Operating Income.  Operating income increased $12.2 million, or 165.3%, to
$19.5 million in 1997 from $7.4 million in 1996. Operating income margin
increased to 21.0% in 1997 from 14.4% in 1996.
 
     Interest and Other Income.  Interest and other income increased $2.0
million to $2.5 million in 1997 from $484,000 in 1996 due to a significant
increase in cash balances of World Access, resulting primarily from the sale of
$115.0 million convertible subordinated notes in October 1997 and proceeds
received from a $26.2 million secondary public equity offering completed in
October 1996.
 
     Interest and Other Expense.  Interest expense increased $1.0 million to
$1.4 million in 1997 from $320,000 in 1996. The increase is primarily due to the
sale of $115.0 million convertible subordinated notes in October 1997 which bear
interest at 4.5%.
 
                                       83
<PAGE>   95
 
     Income Taxes.  World Access' effective income tax rate increased to 36.5%
in 1997 from 9.9% in 1996. The Company's 1996 effective rate was favorably
impacted by the recognition of a $4.1 million deferred tax asset during the year
to reflect the benefits of World Access' remaining net operating loss
carryforward.
 
Year Ended December 31, 1996 Compared to Year Ended December 31, 1995
 
     Sales.  Total sales increased $20.9 million, or 69.2%, to $51.0 million in
1996 from $30.1 million in 1995. Product sales increased to 67.5% of total sales
in 1996 from 57.7% in 1995.
 
     Product sales increased $17.0 million, or 97.9%, to $34.4 million in 1996
from $17.4 million in 1995. The increase related primarily to an additional
$16.1 million of switching products sold by AIT, which was acquired as of May
1995, and $3.6 million of transport and access products sold by Westec and
Sunrise, which were acquired as of October 1995 and January 1996, respectively.
The increases noted above were partially offset by a decrease in the sales of
pay telephone parts in 1996 due to a large one-time order received in 1995.
 
     Service revenues increased $3.8 million, or 30.0%, to $16.6 million in 1996
from $12.8 million in 1995. The increase related to $1.2 million of Westec
repair revenues following its acquisition, $1.7 million of increased circuit
board repair revenues generated by the introduction of new repair services and a
new repair agent contract executed with Century Telephone in July 1995, and
increased contract manufacturing revenues of approximately $1.4 million.
 
     Gross Profit.  Gross profit increased $8.6 million, or 135.7%, to $15.0
million in 1996 from $6.4 million in 1995. Gross profit margin increased to
29.4% in 1996 from 21.1% in 1995. The improved performance resulted from
economies of scale associated with the 69.2% increase in total sales and the
change in sales mix to products, which generally carry a higher gross profit
margin than service revenues.
 
     Gross profit margin on products sold increased to 37.6% in 1996 from 27.2%
in 1995. Excluding the sale of distributed products, gross profit margin for
products sold in 1996 and 1995 was 41.9% and 33.4%, respectively. The improved
margin performance for non-distributed products related primarily to the $16.1
million, or 207.2%, increase in switching products sold by AIT and $2.8 million
of transport and access products sold by Sunrise.
 
     Gross profit margin on service revenues decreased to 12.5% in 1996 from
12.8% in 1995. World Access' gross profit margin for service revenues is subject
to wide fluctuations depending on the sales mix (i.e., circuit board repair and
pay telephone refurbishment have targeted gross profit margins significantly
higher than those of electronic manufacturing services). In addition, circuit
board repair margins declined during 1995 due to increased out-sourced repair
revenues associated with new "one-stop" repair agent programs.
 
     Engineering and Development.  Engineering and development expenses
increased $315,000, or 54.6%, to $892,000 in 1996 from $577,000 in 1995. The
increase in expenses was attributable to the research and product development
activities acquired in connection with the Sunrise acquisition and the formation
of a product development group during the third quarter of 1996. As a result of
the 69.2% increase in total sales, engineering and development expenses
decreased to 1.7% of total sales in 1996 from 1.9% of total sales in 1995.
 
     Selling, General and Administrative Expenses.  Selling, general and
administrative expenses increased $3.1 million, or 98.7%, to $6.2 million in
1996 from $3.1 million in 1995. The increase related primarily to operating
expenses associated with acquisitions, additional salary and related costs for
World Access' Chairman (who received no salary during 1995) and its new
President, and World Access' establishment of a dedicated international sales
and marketing group and corporate business development function in the first
quarter of 1996. As a percentage of total sales, selling, general and
administrative expenses increased to 12.2% in 1996 from 10.4% in 1995.
 
     Amortization of Goodwill.  Amortization of goodwill increased $377,000 to
$534,000 in 1996 from $157,000 in 1995 as a result of the goodwill acquired in
connection with acquisitions.
 
     Operating Income.  Operating income increased $5.8 million to $7.4 million
in 1996 from $1.5 million in 1995. As a percentage of total sales, operating
income increased to 14.4% in 1996 from 5.0% in 1995.
                                       84
<PAGE>   96
 
     Interest and Other Income.  Interest and other income increased $341,000 to
$484,000 in 1996 from $143,000 in 1995 due to an increase in invested cash
balances during 1996, resulting primarily from proceeds received from the $26.2
million secondary public equity offering completed in October.
 
     Interest Expense.  Interest expense decreased $175,000 to $319,000 in 1996
from $494,000 in 1995. The decrease resulted primarily from a decrease in
average debt outstanding in 1996. In October 1996, World Access paid off a $3.9
million term loan with its bank using proceeds received from the secondary
public offering. A reduction in the interest rate on World Access' bank debt due
to the lender's reinstatement of a LIBOR-based interest rate option in July 1995
and an additional one percentage point reduction obtained with World Access' new
bank agreement in March 1996 also contributed to the decrease in interest
expense.
 
     Income Taxes.  World Access' effective income tax rate was 9.9% in 1996.
World Access' 1996 effective rate was significantly impacted by the recognition
of a $4.1 million deferred tax asset during the year to reflect the benefits of
World Access' remaining net operating loss carryforward. No income tax expense
was recorded in 1995 due to the partial recognition of benefits associated with
World Access' net operating loss carryforward.
 
     Salary Incentive Program.  In December 1996, World Access implemented a
voluntary salary reduction program designed to improve World Access' cash flow
during 1997, further align the objectives of World Access' management and
salaried employees with those of World Access' stockholders and potentially
provide World Access with significant future tax deductions. Under the program,
72 exempt salaried employees agreed to forego approximately $826,000 of their
1997 compensation in exchange for 413,019 non-qualified options to purchase
shares of World Access Common Stock at $8.00 per share, its then-current market
value (i.e., one stock option for every $2.00 of compensation). The vesting was
tied to World Access meeting specific operational objectives in 1997, including
pre-defined levels of internal sales growth, ISO 9002 certification and specific
cash management objectives, as well as the installation of certain upgraded
information systems. As of December 31, 1997, these options had become fully
vested.
 
     Under the 1997 program, employees could participate to a maximum level of
50% of their 1997 salaries. World Access' Chairman, President and Chief
Financial Officer each elected to forego 50% of their salary under this program.
This program also provided that if certain levels of pre-tax income were
achieved for 1997, a partial or full repayment of salaries would be made.
Compensation expense related to this program of approximately $250,000, or 30%
of the salaries deferred, was recorded in 1997.
 
     Summary.  World Access' improved operating performance and completion of
the sale of $115.0 million of convertible subordinated notes due 2002 (the
"Notes") has significantly enhanced its financial strength and improved its
liquidity. World Access believes that existing cash balances, available
borrowings under World Access' line of credit and cash projected to be generated
from operations will provide World Access with sufficient capital resources to
support its current working capital requirements and business plans for at least
the next 12 months.
 
Year 2000
 
     As a result of certain computer programs being written using two digits
rather than four to define the applicable year, any of World Access' computer
systems that have date sensitive software may recognize a date using "00" as the
year 1900 rather than the year 2000 (the "Year 2000 Issue"). This causes
programs that perform arithmetic operations, comparisons or date sorts to
possibly generate erroneous results when the program is required to process
dates from both centuries. This could result in a system failure, incorrect data
and other business disruptions, including, among other things, a temporary
inability to procure materials, process transactions, send invoices and service
customers.
 
     World Access is in the process of evaluating its operating systems to
determine what modifications are necessary to make such systems compatible with
the year 2000 requirements. These systems include business information systems,
development tools and test beds, and manufacturing equipment and processes.
World Access has recently implemented a new business information system at
several of its locations that is certified to be year 2000 compliant by its
supplier. Independent tests by World Access have verified this compliance
 
                                       85
<PAGE>   97
 
and the system is expected to be deployed company-wide by mid-1999. World Access
plans on engaging an outside consulting firm in November 1998 to perform a
detailed year 2000 review of its development and manufacturing systems. The
costs to ensure compliance of these systems (including computer equipment,
software upgrades and assessment fees) by mid-1999 is currently estimated at
approximately $700,000.
 
     In addition, World Access is in the process of developing a plan whereby it
will review the year 2000 readiness of its customers and suppliers. In doing so,
it will undertake appropriate internal reviews and will contact certain of its
significant customers to assess, to the extent possible, Year 2000 Issues
related to World Access' products. In that regard, World Access has identified
that certain of its products, including NACT's NTS 1000 Billing System, are not
year 2000 compliant. NACT is in the process of modifying the NTS 1000 Billing
System to overcome the two digit limitation. This modification of the NTS 1000
software is anticipated to be completed by the first calendar quarter in 1999 at
an estimated cost of $115,000. World Access is in the process of releasing new
versions of such products and making necessary modifications to existing
products to address the Year 2000 Issue. World Access expects that many of its
customers will upgrade to the new products. However, there can be no assurance
that World Access customers will upgrade to the new year 2000 compliant products
or that the modifications planned to the certain of the existing products will
be successful or completed in a timely manner. Although World Access believes
that it can address year 2000 readiness issues related to its products, there
may still be disruptions and/or product failures that are unforeseen.
 
     World Access also intends to request assurances from its major suppliers
that they are addressing the Year 2000 Issue and that the products and services
procured or used by World Access will function properly or be available without
interruption in the year 2000. A detailed questionnaire was mailed to all major
suppliers in September 1998. Appropriate Year 2000 warranties will be requested
from key suppliers to World Access. Nevertheless, it will be impossible to fully
assess the potential consequences if service interruptions occur from suppliers
or in infrastructure areas such as utilities, communications, transportation,
banking and government. As a result, World Access also intends to develop a
business continuity plan by mid-1999 to minimize the impact of such external
events.
 
     While World Access' efforts to address Year 2000 Issues will involve
additional costs and the time and effort of a number of employees, World Access
believes, based on currently available information, that it will be able to
properly manage its total year 2000 exposure. There can be no assurance,
however, that World Access will be successful in its effort or that the computer
systems of other companies on which World Access will rely will be timely
modified, or that a failure to modify such systems by another company, or
modifications that are incompatible with World Access' systems, would not have a
material adverse effect on World Access' business, financial condition or
results of operations.
 
Recent Accounting Pronouncements
 
     In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 130, "Reporting Comprehensive Income" (SFAS
130). SFAS 130 establishes standards for reporting and disclosure of
comprehensive income and its components. This statement will be effective for
the year ended December 31, 1998. Management believes this statement will not
have a material impact on World Access' financial statements.

Results of Operations for Three Months Ended June 30, 1998 and 1997 and Six
Months Ended June 30, 1998 and 1997
 
     The following table sets forth items in World Access' Consolidated
Statements of Operations as a percentage of total revenues.
 
     World Access' sales during the first six months of 1998 included
approximately $30.0 million from its AIT and CIS subsidiaries. AIT sells new and
used Northern Telecom switching systems, add-on frames and circuit cards. CIS
sells re-engineered cellular base stations and related mobile network equipment.
These operations depend on a consistent supply of equipment to sustain their
revenue levels. Additionally, individual sales by AIT and CIS are relatively
large ($500,000 to $2.0 million), which subjects World Access to the risk of
revenue fluctuations in the event that customers adjust the timing of their
orders.

  Three Months Ended June 30, 1998 Compared to Three Months Ended June 30, 1997
 
     Sales.  Total sales increased $23.5 million, or 97.8%, to $47.5 million in
the second quarter of 1998 from $24.0 million in the second quarter of 1997. The
percentage of product sales to total sales increased to 87.6% in the second
quarter of 1998 from 81.0% in the second quarter of 1997.
 
     Product sales increased $22.2 million, or 113.9%, to $41.6 million in the
second quarter of 1998 from $19.4 million in the second quarter of 1997. The
increase related to sales generated by ATI and NACT which
 
                                       87
<PAGE>   99
 
were acquired effective February 1, 1998 and March 1, 1998, respectively, and
increases in sales of World Access' international switching product, the CDX,
and it's WX-5501 line card.
 
     Service revenues increased $1.3 million, or 29.2%, to $5.9 million in the
second quarter of 1998 from $4.6 million in the second quarter of 1997. The
increase related to additional revenues attributable to the Galaxy acquisition,
which was acquired effective July 1, 1997. This increase was offset by a decline
in electronic manufacturing revenues resulting from a strategic decision to
begin utilizing World Access' manufacturing capacity for new World Access
products rather than service outside contract manufacturing customers.
 
     Gross Profit.  Gross profit increased $12.0 million, or 141.7%, to $20.5
million in the second quarter of 1998 from $8.5 million in the second quarter of
1997. Gross profit margin increased to 43.2% in the second quarter of 1998 from
35.3% in the second quarter of 1997. The improved performance resulted from
economies of scale associated with the 97.8% increase in total sales and the
change in sales mix to products, which generally carry a higher gross profit
margin than service revenues.
 
     Gross profit margin on products sold increased to 46.5% in the second
quarter of 1998 from 40.7% in the second quarter of 1997. The improved margins
related to the NACT and ATI sales of proprietary equipment and systems and the
increase in sales of CDX equipment, all of which generally carry margins in
excess of 45%. World Access' refurbished switching products experienced declines
in gross margin during the second quarter of 1998 primarily related to margin
pressure on sales of Northern Telecom add-on frames and related circuit boards.
 
     Gross profit margin on service revenues increased to 19.4% in the second
quarter of 1998 from 12.4% in the second quarter of 1997. The improvement was
due to the addition of revenues from Galaxy.
 
     Engineering and Development.  Engineering and development expenses
increased $1.4 million, or 318.5%, to $1.8 million in the second quarter of 1998
from $429,000 in the second quarter of 1997. The increase in expenses was
attributable to the acquisitions of NACT and ATI and the continued expansion of
World Access' development group during 1998. Total engineering and development
expenses increased to 3.8% of total sales in the second quarter of 1998 from
1.8% of total sales in the second quarter of 1997.
 
     Selling, General and Administrative Expenses.  Selling, general and
administrative expenses increased $2.3 million, or 92.2%, to $4.7 million in the
second quarter of 1998 from $2.4 million in the second quarter of 1997. The
increase related primarily to expenses associated with the operations of NACT,
ATI and Galaxy, which were acquired subsequent to the second quarter of 1997. As
a percentage of total sales, selling, general and administrative expenses
decreased to 9.9% in the second quarter of 1998 from 10.1% in the second quarter
of 1997.
 
     Amortization of Goodwill.  Amortization of goodwill increased $638,000 to
$1.0 million in the second quarter of 1998 from $380,000 in the second quarter
of 1997, as a result of the goodwill acquired in connection with the NACT, ATI,
and Galaxy acquisitions and additional goodwill recorded related to earnout
performances for the CIS, AIT and Galaxy acquisitions.
 
     AIT, CIS, Galaxy, ATI and NACT (collectively representing approximately 95%
of the net goodwill of World Access) are all operating at profitability levels
in excess of management's expectations and the related risk of impairment in the
foreseeable future is believed to be low. Westec and Sunrise are operating below
management's expectations and may have difficulty achieving future sales growth.
Although management believes there has been no permanent impairment in the value
of the Westec and Sunrise goodwill to date, management will continue to monitor
closely the value of Westec and Sunrise goodwill throughout 1998 and 1999.
 
     Operating Income.  Operating income increased $7.8 million, or 148.3%, to
$13.0 million in the second quarter of 1998 from $5.2 million in the second
quarter of 1997. Operating income margin increased to 27.4% in the second
quarter of 1998 from 21.8% in the second quarter of 1997.
 
     Interest and Other Income.  Interest and other income increased $476,000,
or 211.6%, to $701,000 in the second quarter of 1998 from $225,000 in the second
quarter of 1997 due to increased invested cash balances of
 
                                       88
<PAGE>   100
 
World Access, resulting primarily from proceeds received from a $115.0 million
convertible note offering completed in October 1997.
 
     Interest Expense.  Interest expense increased to $1.5 million in the second
quarter of 1998 from $24,000 in the second quarter of 1997. The increase is due
to the $115.0 million convertible note offering.
 
  Six Months Ended June 30, 1998 Compared to Six Months Ended June 30, 1997
 
     Sales.  Total sales increased $38.9 million, or 88.0%, to $83.2 million in
the first six months of 1998 from $44.3 million in the first six months of 1997.
The percentage of product sales to total sales increased to 83.9% in the first
six months of 1998 from 78.9% in the first six months of 1997.
 
     Product sales increased $34.9 million, or 100.0%, to $69.8 million in the
first six months of 1998 from $34.9 million in the first six months of 1997. The
increase related to sales generated by ATI and NACT which were acquired
effective February 1, 1998 and March 1, 1998, respectively, and increases in
sales of World Access' international switching product, the CDX, and it's
WX-5501 line card.
 
     Service revenues increased $4.0 million, or 43.3%, to $13.4 million in the
first six months of 1998 from $9.4 million in the first six months of 1997. The
increase related to additional revenues attributable to the Galaxy acquisition.
This increase was offset by a decline in electronic manufacturing revenues
resulting from a strategic decision to begin utilizing World Access'
manufacturing capacity for new World Access products rather than service outside
contract manufacturing customers and in World Access' circuit board repair
business.
 
     Gross Profit.  Gross profit increased $17.3 million, or 118.2%, to $32.0
million in the first six months of 1998 from $14.7 million in the first six
months of 1997. Gross profit margin increased to 38.5% in the first six months
of 1998 from 33.2% in the first six months of 1997. The improved performance
resulted from the 88.0% increase in total sales and the change in sales mix to
products, which generally carry a higher gross profit margin than service
revenues.
 
     Gross profit margin on products sold increased to 44.1% in the first six
months of 1998 from 38.4% in the first six months of 1997. The improved margins
related to the NACT and ATI sales of proprietary equipment and systems and the
increase in sales of CDX equipment, all of which generally carry margins in
excess of 45%. World Access' refurbished switching products experienced declines
in gross margin during the first six months of 1998 primarily related to margin
pressure on sales of Northern Telecom add-on frames and related circuit boards.
 
     Gross profit margin on service revenues was 9.1% in the first six months of
1998 as compared to 13.5% in the first six months of 1997. Gross profit margin
excluding the special charge was 34.2% in the first six months of 1998. The
improvement was due to the addition of revenues from Galaxy, which was acquired
effective July 1, 1997.
 
     Engineering and Development.  Engineering and development expenses
increased $1.8 million, or 246.6%, to $2.6 million in the first six months of
1998 from $745,000 in the first six months of 1997. The increase in engineering
and development expenses was attributable to the acquisitions of NACT and ATI
and the continued expansion of World Access' development group during 1998.
Total engineering and development expenses increased to 3.1% of total sales in
the first six months of 1998 from 1.7% of total sales in the first six months of
1997.
 
     Selling, General and Administrative Expenses.  Selling, general and
administrative expenses increased $3.5 million, or 82.3%, to $7.9 million in the
first six months of 1998 from $4.4 million in the first six months of 1997. The
increase related primarily to expenses associated with the operations of NACT,
ATI and Galaxy, which were acquired subsequent to the second quarter of 1997. As
a percentage of total sales, selling, general and administrative expenses
decreased to 9.6% in the first six months of 1998 from 9.8% in the first six
months of 1997.
 
     Amortization of Goodwill.  Amortization of goodwill increased $1.4 million
to $2.0 million in the first six months of 1998 from $592,000 in the first six
months of 1997, as a result of the goodwill acquired in
                                       89
<PAGE>   101
 
connection with the NACT, ATI, and Galaxy acquisitions and additional goodwill
recorded related to earnout performances for the CIS, AIT and Galaxy
acquisitions.
 
     Operating Income Before Special Charges.  Operating income before special
charges increased $14.1 million to $23.0 million in the first six months of 1998
from $8.9 million in the first six months of 1997. Operating income margin
before special charges increased to 27.6% in the first six months of 1998 from
20.2% in the first six months of 1997.
 
     Interest and Other Income.  Interest and other income increased $1.4
million, or 232.7%, to $2.0 million in the first six months of 1998 from
$592,000 in the first six months of 1997 due to increased invested cash balances
of World Access, resulting primarily from proceeds received from a $115.0
million convertible note offering completed in October 1997.
 
     Interest Expense.  Interest expense increased to $3.0 million in the first
six months of 1998 from $53,000 in the first six months of 1997. The increase is
due to the $115.0 million convertible note offering.
 
Purchased In-Process R&D
 
     Special charges in the first quarter of 1998 included $50.0 million for
in-process research and development related to the first quarter 1998
acquisitions of a 67.3% interest in NACT and ATI. Purchased in-process research
and development, which consists of the value of NACT and ATI products in the
development stage that are not considered to have reached technological
feasibility, were expensed in accordance with applicable accounting rules. World
Access expects to record an additional in-process research and development
charge of approximately $22.0 million in the fourth quarter of 1998 in
connection with the acquisition of the remaining 32.7% of NACT.
 
     The Income Approach was utilized to value the acquired research and
development technologies in the NACT Acquisition. The Income Approach values
technologies by projecting the potential cash flows related to those
technologies and discounting the cash flows to their present values using a
discount rate reflective of the risk of achieving the cash flows. The projected
cash flows include estimates of the remaining costs to complete the in-process
technologies.
 
     NACT provides advanced telecommunications switching platforms with
integrated applications software and network telemanagement capabilities. NACT
designs, develops, and manufacturers all hardware and software elements
necessary for a fully integrated, turnkey telecommunications switching solution.
The nature of the in-process research and development was such that
technological feasibility had not been attained as of the date of acquisition.
Failure to attain technological feasibility, especially given the high degree of
customization required for complete integration into the NACT solution, would
have rendered partially designed hardware and software useless for other
applications. Incomplete design of hardware and software coding would create a
non-connective, inoperable product that would have no alternative use.
 
     NACT's business plan called for a shift in market focus to larger
customers, both domestic and international; therefore, NACT had numerous
projects in development at the time of the acquisition. Additionally, the
pending completion of a major release of NACT's billing system required
significant development efforts to ensure continued integration with NACT's
product suite.
 
     NACT had nine principal projects in the development pipeline at the time of
acquisition. Most major projects had several ongoing sub-projects (e.g., a
hardware design project and a software design project). These projects included
significant redevelopment of some existing products and the creation of new
products. The research and development projects were at various stages of
development. Most new or redeveloped products were scheduled for release in
1998, while several others were scheduled for release in 1999. None of the
in-process projects considered in the write-off had attained technological
feasibility.
 
     For all in-process technologies, management estimated remaining costs to
complete. These estimates were $3.3 million for 1998, and $1 million for 1999.
The expected sources of funding were scheduled research and development expenses
from the operating budget of NACT provided by the operating assets and
liabilities of NACT.

     The Income Approach was also used to value the acquired research and
development technologies in the ATI acquisition.
 
     ATI develops and manufactures a series of high-performance digital
microwave/millimeter radio equipment. Their products reach across all frequency
bands and data rates and offer numerous features. The nature of the in-process
research and development was such that technological feasibility had not been
attained as of the date of acquisition. Failure to attain technological
feasibility would have rendered partially designed equipment useless for other
applications. ATI's products are designed for specific frequency bandwidths and,
as such, are highly customized to those bandwidths and the needs of customers
wishing to operate in them. Products only partially completed for certain
bandwidths cannot be used in other bandwidths.
 
     At the time of acquisition, ATI's primary product lines were FSK+, Compact,
and QAM. ATI's management determined the following percentages of each product
line were in-process technologies:
 
<TABLE>
<S>                                              <C>
FSK+:                                            15.0% of units in development

QAM:                                             100.0% of units in development

     Between each product line, various stages of development had been reached.
Additionally, within each product line, different units had reached various
stages of development. Of the products management considered in-process, none
had attained technological feasibility.
 
     For all in-process products, management estimated remaining costs to
complete to be $3.1 million for 1998, $7.2 million for 1999, $7.6 million for
2000, $5.1 million for 2001, and $1.1 million for 2002. The expected sources of
funding were scheduled R&D expenses from the operating budget of ATI provided by
the operating assets and liabilities of ATI.
 
Special Charges
 
     In January 1998, World Access' senior management decided that the following
actions were necessary to streamline operations and position World Access to
service anticipated sales growth:
 
     - Close down the existing Orlando, Florida manufacturing and repair
       facility. Move the manufacturing of certain World Access products to the
       company's Alpharetta, Georgia manufacturing facility.
 
     - Exit the contract manufacturing business.
 
     - Close down four Lakeland, Florida facilities and move AIT operations to a
       new facility in Orlando, Florida. Repair operations would be integrated
       with AIT in this new facility.
 
     - Close down Westec's facility in Scottsdale, Arizona and integrate its
       operations into ATI's facility in Wilmington, Massachusetts.
 
     Shortly thereafter, senior management informed the operating management of
the applicable divisions. All Orlando and Lakeland employees were informed in
January and Westec employees were informed in February (subsequent to the
closing of the ATI acquisition).
 
     Management carefully reviewed the provisions of EITF 94-3 in determining
which costs related to the above actions should be included in a first quarter
special charge. No costs were included in the charge that would derive future
economic benefit to World Access, e.g., relocation of existing employees,
recruiting and training of new employees and facility start-up costs. The
special charge consisted of:

     Severance and termination benefits were clearly communicated up front to
the approximately 60 employees who lost their jobs as a direct result of the
consolidations. Affected employees were notified shortly after the January and
February employee meetings. Benefits were determined consistent with World
Access' severance policy of one week of pay for each full year of service
(minimum of two weeks) and continued benefits through the month severance pay is
exhausted. Approximately 10 of these employees were involuntarily terminated in
February and March, approximately 40 employees were involuntarily terminated in
April and approximately 10 employees were involuntarily terminated in June. The
Orlando and Lakeland facilities were closed in April and the Scottsdale facility
was closed in June. The actual severance and termination benefit costs incurred
by World Access were not materially different from the $550,000 recorded in the
special charge.
 
     The idle facility and equipment portion of the special charge included the
write-off of "old Orlando", Lakeland and Scottsdale leasehold improvements,
provisions for the estimated costs to terminate idle facility and equipment
leases, the write-off of Orlando manufacturing equipment not relocated to the
company's Alpharetta facility and certain phase-down expenses associated with
the six facilities closed down. As of the date of this Joint Proxy
Statement/Prospectus, World Access does not expect the actual costs for these
items to be materially different from amounts recorded in the special charge.
 
     As previously noted, all activities that resulted in the first quarter
special charge were completed by World Access as of June 30, 1998. Of the
$3,240,000 special charge, approximately $1.4 million related to assets directly
written-off of amounts charged to the reserve in the first quarter. As of June
30, 1998, the accrual for special charges was approximately $600,000, which
consisted primarily of lease termination losses expected to be incurred.
 
Liquidity and Capital Resources
 
     Overview.  Cash management is a key element of World Access' operating
philosophy and strategic plans. Acquisitions to date have been structured to
minimize the cash element of the purchase price and ensure that appropriate
levels of cash are available to support the increased product development,
marketing programs and working capital normally associated with the growth
initiatives of acquired businesses. As of June 30, 1998, World Access had $61.2
million of cash and investments and $5.7 million in borrowings available under
its credit line to support its current working capital requirements and
strategic growth initiatives.
 
     Operating Activities.  Cash provided from operating activities was $3.0
million in the first six months of 1998 as compared to cash used by operations
of $2.6 million in the first six months of 1997.
 
     Accounts receivable increased $21.5 million, or 106.4%, to $41.8 million at
June 30, 1998 from $20.3 million at December 31, 1997. This was due to the
acquisitions of NACT, ATI and Galaxy and increased sales activity at World
Access (second quarter 1998 sales were $47.5 million as compared to fourth
quarter 1997 sales of $21.3 million). Average days sales outstanding at June 30,
1998, March 31, 1998 and December 31, 1997 were approximately 80 days, 90 days
and 81 days, respectively. World Access' transition into equipment sales has
caused an increase in days sales outstanding. World Access' equipment sales tend
to include longer payment terms than the historical repair and refurbishment
businesses. In addition, World Access' sales to international customers have
increased during the last twelve months. International sales generally have
payment terms of 90 to 120 days. World Access also has recently begun to enter
into long-term notes receivable with selected customers. To maximize cash flow,
World Access sells the notes where possible on either a non-recourse or recourse
basis to a third party financing institution.
 
     Inventories increased $12.1 million, or 53.7%, to $34.5 million at June 30,
1998 from $22.4 million at December 31, 1997. This increase was due to the
acquisitions of NACT and ATI, a planned build-up of CDX switching and WX-5501
inventories related to the closure of World Access' Orlando manufacturing
facility and an increase in AIT and CIS inventories to support future orders.
The increases above were offset by the $3.4 million provision for obsolete and
redundant inventories related to the consolidation program initiated in the
first quarter of 1998 (see "Special Charges").
 
                                       92

     Investing Activities.  Cash used by investing activities, primarily for the
acquisitions of businesses, was $69.8 million and $4.6 million for the first six
months of 1998 and 1997, respectively.
 
     On December 31, 1997, World Access entered into a stock purchase agreement
with GST and GST USA to acquire 5,113,712 shares of NACT common stock owned by
GST USA, Inc. ("GST USA"), representing approximately 63% of the outstanding
shares of NACT common stock (the "NACT Stock Acquisition"). On February 27,
1998, the NACT Stock Acquisition was completed with GST USA receiving $59.7
million in cash and 1,429,907 restricted shares of World Access Common Stock.
These shares had an initial fair value of approximately $26.9 million. This
transaction increased World Access' ownership of NACT to 67.3%.
 
     On February 24, 1998 World Access entered into a merger agreement with NACT
pursuant to which World Access agreed to acquire all of the shares of NACT
common stock not already then owned by World Access or GST USA. Pursuant to the
terms of the merger agreement, each share of NACT common stock was converted
into 1.0469 shares of World Access Common Stock. This merger was consummated on
October 28, 1998.
 
     On December 24, 1997, World Access entered into an agreement to acquire
ATI. On January 29, 1998, the transaction was completed in its final form
whereby ATI was merged with and into CIS (the "ATI Merger"). In connection with
the ATI Merger, the stockholders of ATI received approximately $300,000 and
424,932 restricted shares of World Access Common Stock. These shares had an
initial fair value of approximately $6.5 million.
 
     In addition to the 424,932 shares noted above, the stockholders of ATI were
issued 209,050 restricted shares of World Access Common Stock. These shares were
immediately placed into escrow and will be released to the stockholders of ATI
contingent upon the realization of predefined levels of pre-tax net income from
ATI's operations during calendar years 1998 and 1999.
 
     In December 1997, World Access loaned ATI approximately $4.5 million. ATI
used $2.6 million of the proceeds to pay off its line of credit with a bank and
the remainder for working capital purposes. The note receivable from ATI is
included in Other assets on World Access' December 31, 1997 balance sheet.
During the first quarter of 1998, the note receivable was included in World
Access' purchase price of ATI.
 
     During the first six months of 1998 and 1997, World Access invested $5.9
million and $1.1 million, respectively, in capital expenditures. World Access
has invested approximately $3.7 million during 1998 related to the establishment
of the new manufacturing facility in Alpharetta, Georgia. The remaining
expenditures during 1998 were primarily for computer network and related
communications equipment designed to upgrade World Access' management
information systems and facilitate the integration of acquisitions, and facility
improvements required in connection with World Access' growth.
 
     World Access began capitalizing software development costs in the fourth
quarter of 1997. Software development costs are capitalized upon the
establishment of technological feasibility of the product. During the first six
months of 1998, World Access capitalized approximately $1.8 million of software
development costs.
 
     Financing Activities.  Cash provided from financing activities was $6.4
million and $5.4 million for the first six months of 1998 and 1997,
respectively.
 
     On October 1, 1997, Old World Access sold $100.0 million in aggregate
principal amount of Notes under Rule 144A of the Securities Act of 1933. The
Notes bear interest at the rate of 4.5% per annum, are convertible into World
Access Common Stock at an initial price of $37.03 per share and mature on
October 1, 2002. Interest on the Notes is payable on April 1 and October 1 of
each year, commencing on April 1, 1998. The Notes are general unsecured
obligations of Old World Access and are subordinate in right of payment to all
existing and senior indebtedness. The Notes have been guaranteed by World
Access. The Company received $97.0 million from the sale of the Notes, after the
initial purchasers' discount fees of $3.0 million.
 
     In addition to the Notes sold on October 1, 1997, World Access granted the
initial purchasers an option to purchase up to an additional $15.0 million in
Notes to cover over-allotments. On October 28, 1997, the
 
                                       93
<PAGE>   105
 
initial purchasers exercised the over-allotment option in full and World Access
received an additional $14.6 million, after the application of the initial
purchasers' discount fees.
 
     The total discount fees of $3,450,000, along with approximately $550,000 of
legal, accounting, printing and other expenses (the "Debt issuance costs") are
being amortized to expense over the five year term of the Notes. Debt issuance
costs of approximately $3.4 million, net of amortization, are included in Other
assets on World Access' June 30, 1998 balance sheet.
 
     As of June 30, 1998, World Access had borrowings of $4.3 million
outstanding under its $10.0 million revolving line of credit. Borrowings under
World Access' line of credit are secured by a first lien on substantially all
the assets of World Access. The bank agreement, which expires in March 2001,
contains standard lending covenants, including financial ratios, restrictions on
dividends and limitations on additional debt and the disposition of company
assets. Interest is paid at the rate of prime plus 1 1/4% or LIBOR plus 2 1/2%,
at the option of World Access. As of the date hereof, there were no amounts
outstanding under World Access' line of credit.
 
     During the first six months of 1998 and 1997, World Access received
approximately $7.3 million and $2.6 million, respectively, in cash, including
related federal income tax benefits, from the exercises of incentive and
non-qualified stock options and warrants by World Access' directors and
employees.
 
     Income Taxes.  As a result of the exercises of non-qualified stock options
and warrants by World Access' directors and employees, World Access has realized
a federal income tax benefit of approximately $4.2 million for the first six
months of 1998. Although this tax benefit does not have any effect on World
Access' provision for income tax expense, it represents a significant cash
benefit to World Access. This tax benefit is accounted for as a decrease in
current income taxes payable and an increase in capital in excess of par value.
 
     Summary.  World Access' improved operating performance and completion of
the sale of $115.0 million of Notes in 1997 has significantly enhanced its
financial strength and improved its liquidity. World Access believes that
existing cash balances, available borrowings under World Access' line of credit
and cash projected to be generated from operations will provide World Access
with sufficient capital resources to support its current working capital
requirements and business plans for at least the next 12 months.

Quarterly Operating Results
 
     The following table presents unaudited quarterly operating results for each
of World Access' last ten quarters. This information has been prepared by World
Access on a basis consistent with World Access' audited consolidated financial
statements and includes all adjustments, consisting only of normal recurring
accruals, that World Access considers necessary for a fair presentation in
accordance with GAAP. Such quarterly results are not necessarily indicative of
future operating results. This information should be read in conjunction with
World Access' consolidated financial statements and notes thereto included
elsewhere herein.
 
     The following includes the results of operations for businesses acquired
from their respective dates of acquisition as follows: CIS as of January 1, 1997
and Galaxy as of July 1, 1997. Net income per share is presented on a diluted
basis.
 
     World Access' quarterly operating results have fluctuated significantly in
the past. As World Access increases its number of telecommunications product
offerings, its future quarterly operating results may vary significantly
depending on factors such as the timing and shipment of significant orders, new
product offerings by World Access and its competitors, market acceptance of new
and enhanced versions of World Access' products, changes in pricing policies by
World Access and its competitors, the availability of new technologies, the mix
of distribution channels through which World Access' product are sold, the
inability to obtain sufficient supplies of sole or limited source components for
World Access' products, gains or losses of significant customers, the timing of
customers' upgrade and expansion programs, changes in the level of operating
expenses, the timing of acquisitions, seasonality and general economic
conditions.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS OF NACT
 
Overview
 
     NACT provides advanced telecommunications switching platforms with
integrated applications software and network telemanagement capabilities. During
the period from 1987 through 1989, NACT developed and began selling its LCX 120C
switch application product and NTS 1000 billing system. During the period from
1990 through 1995, NACT developed enhancements to the LCX, including T-1
capability, enhancement of its prepaid debit card services, automated operator,
international call back and call reorigination. During the same period, NACT
also developed the Master Control Unit. In May 1996, NACT completed development
of and began selling the STX, an integrated digital tandem switching system that
includes proprietary systems software that enables standard applications such as
1+ and optional advanced applications such as international call
back/reorigination, prepaid debit card and prepaid cellular.
 
     NACT sells its products in the United States to enhanced telecommunications
network service providers through a direct sales force. During the fourth
quarter of fiscal 1997, NACT sold its first STX switching and NTS billing
systems outside the United States. NACT intends to continue to expand the
marketing of its products both domestically and internationally. Currently, NACT
also provides long distance network carrier service to facilities management
customers with operations primarily in Brazil and Eastern Europe.
 
     In response to customer demand, in fiscal 1995, NACT began offering
facilities management and network carrier services. Facilities management
services enable a customer to concentrate on marketing its products while NACT
maintains such customer's switch(es) in NACT's facilities for a fee. Such
services can include network carrier usage in addition to the management of a
switch. NACT provides network carrier usage at competitively priced domestic and
international rates. Revenues associated with such facilities management
services, including network carrier usage, are presented in NACT's financial
statements as network carrier sales. The gross profit associated with such sales
are substantially lower than those associated with product sales. In addition,
given the small number of customers and the high volume of revenues generated
from an individual customer through network carrier sales, the loss or gain of
one or more customers could cause a significant fluctuation in NACT's quarterly
revenues.
 
     In 1995, NACT formed Wins, Inc., a wholly-owned subsidiary ("Wins"), to
provide specialized long distance services (e.g., prepaid debit card and
international call back/reorigination) to potential switching system customers
who wanted to enter the specialized long distance service market before making a
major capital investment in switching equipment. NACT's financial statements for
the fiscal year ended September 30, 1995 include the accounts of NACT and Wins.
On September 30, 1995, NACT transferred ownership and operation of Wins to GST
USA in the form of a dividend accounted for at historical cost. From October 1,
1995 through September 30, 1996, NACT provided carrier services to GST USA for
the Wins operation. NACT ceased providing carrier services to Wins on September
30, 1996. Therefore, no revenue has been recognized by NACT from the Wins
operation after September 30, 1996.
 
     GST USA acquired a 100% interest in NACT's common stock, $.01 par valve
(the "NACT Common Stock"), through a series of purchases of newly issued shares
and shares owned by former stockholders of NACT from September 1993 through
September 30, 1995. GST USA accounted for the acquisition using the purchase
method of accounting. The excess of the purchase price over the fair value of
the assets acquired was accounted for by GST USA as product support contracts,
software development costs, and goodwill. In accordance with the requirements of
the Commission, NACT's financial statements reflect these intangible assets on
its balance sheet, with related amortization recorded in cost of goods sold and
other operating expense in the respective years. Product support contracts and
software development costs are being amortized over a five-year straight-line
period and goodwill is being amortized over a 20-year straight-line period.
 
     In the second quarter of fiscal 1997, NACT completed an initial public
offering of its common stock, pursuant to which NACT and its parent company, GST
Telecommunications, Inc. ("GST"), sold two million and one million shares,
respectively, of NACT Common Stock, resulting in net proceeds to NACT and GST of
approximately $18.1 million and $10.0 million, respectively. As a result of this
initial public offering, GST's interest in NACT was reduced to approximately
63%.
 
                                       97
<PAGE>   109
 
     On September 30, 1997, GST announced that it had retained Hambrecht & Quist
LLC to explore alternatives for monetizing its 63% interest in NACT, including a
potential sale of some or all of GST's shares of NACT's capital stock to one or
more strategic investors. On December 31, 1997, GST and GST USA entered into the
NACT Stock Purchase Agreement with World Access, and on February 27, 1998, World
Access purchased from GST USA all of the shares of NACT Common Stock held by GST
USA.
 
Fiscal 1997 Compared to Fiscal 1996
 
Results of Operations
 
     Total Revenues.  Revenues increased by 70.1% from $16.3 million in fiscal
1996 to $27.7 million in fiscal 1997. Product sales increased by 121.4% from
$9.9 million in fiscal 1996 to $22.0 million in fiscal 1997 primarily due to
sales of the STX switching systems, which NACT began selling in May 1996.
Network carrier sales increased by 51.1% from $3.8 million in fiscal 1996 to
$5.7 million in fiscal 1997 due to increased carrier usage volumes from existing
network carrier customers. NACT generated $2.6 million in revenues from sales of
network carrier usage to Wins in 1996. On October 1, 1996, NACT discontinued
providing network carrier usage to Wins.
 
Gross Profit
 
     Product Sales.  Gross profit on product sales increased 147.8% from $6.0
million in fiscal 1996 to $14.8 million in fiscal 1997 due to increases in sales
volumes and gross profit per unit from the sale of larger port capacity STX
switching systems. Gross profit on product sales as a percentage of product
sales increased from 60.3% in fiscal 1996 to 67.5% in fiscal 1997 primarily due
to sales of larger port capacity STX switching systems, which have higher gross
profit margins, in fiscal 1997 and due to lower margins on STX switching systems
in fiscal 1996 as a result of special pricing on its initial sales of STX
switching systems and the discounting of LCX systems prior to the release of the
STX system in May 1996.
 
     Network Carrier Sales.  Gross profit on network carrier sales decreased
42.6% from $0.4 million in fiscal 1996 to $0.2 million in fiscal 1997 due to a
decrease in the prices charged for international carrier traffic to NACT's
network carrier customers and due to the non-recognition of profit on network
carrier sales during the fourth quarter of fiscal 1997 to Overseas Telecom (a
network carrier customer).
 
     Wins.  In fiscal 1997, there were no sales to GST USA for the Wins
operations. In fiscal 1996, NACT provided network carrier services at cost to
GST USA for the Wins operations.
 
     Overall.  Gross profit increased 144.0% from $6.0 million in fiscal 1996 to
$14.7 million in fiscal 1997 primarily due to increases in sales volumes and
gross profit per unit from the sale of larger port capacity STX switching
systems. Gross profit as a percentage of net revenues increased from 37.0% in
fiscal 1996 to 53.1% in fiscal 1997 primarily due to sales of larger port
capacity STX switching systems, which have higher gross profit margins, in
fiscal 1997 and due to lower margins on STX switching systems in fiscal 1996 as
a result of special pricing on initial sales of STX switching systems and the
discounting of LCX systems prior to the release of the STX system in May 1996.
 
     Research and Development.  Research and development expenses increased by
76.4% from $1.4 million in fiscal 1996 to $2.4 million in fiscal 1997 primarily
due to the expansion of NACT's engineering staff and an increase in expenditures
for planning and implementation of several hardware and software research and
development projects designed to enhance the STX switching and NTS billing
systems. Capitalized software development costs were $0.4 million and $0.8
million in fiscal 1996 and 1997, respectively.
 
     Selling and Marketing.  Selling and marketing expenses increased by 162.7%
from $1.0 million in fiscal 1996 to $2.5 million in fiscal 1997 due to the
hiring of additional senior sales personnel, the opening of new domestic sales
offices, increased advertising and trade show expenditures, and increased
commissions paid to sales personnel as a result of the increase in NACT's
product sales.
 
     General and Administrative.  General and administrative expenses increased
14.8% from $3.0 million in fiscal 1996 to $3.5 million in fiscal 1997 primarily
due to the hiring of new personnel in NACT's technical
 
                                       98
<PAGE>   110
 
support, training, finance, and administrative departments to support NACT's
increased sales, shipments, and installations of STX switching and NTS billing
systems. Also, in fiscal 1997, additional expenses were incurred by NACT as a
result of the construction of and move into the Company's new headquarters/
manufacturing facility on July 1, 1997.
 
     Amortization of Acquired Intangibles.  NACT has included amortization of
acquired intangibles as a component of both cost of sales and operating
expenses. These intangibles arose as a result of the acquisition of NACT by GST
USA. GST USA accounted for the acquisition using the purchase method of
accounting. The excess of the purchase price over the fair value of the assets
acquired was assigned by GST USA as product support contracts, software
development costs and goodwill and, in accordance with requirements of the
Commission, has been included in the balance sheet of NACT with related
amortization recorded in cost of goods sold and other operating expenses.
Product support contracts and software development costs are being amortized
over a five-year straight-line period and goodwill is being amortized over a
20-year straight-line period.
 
     Other Income and Expense.  Other income, net of $0.1 million in fiscal
1996, increased to $0.5 million in fiscal 1997 due to an increase in interest
income during fiscal 1997 resulting from investing the cash proceeds received
from the initial public offering completed in March of 1997.
 
     Income Taxes.  NACT recorded provisions for income taxes with effective
rates of 28.8% and 39.4% of income before taxes for fiscal 1996 and 1997,
respectively. The increase in the effective tax rate in 1997 is primarily a
result of increased profitability. Future effective tax rates are expected to be
in excess of statutory rates during the amortization period of the acquired
goodwill from GST USA because the goodwill is not deductible for tax purposes.
 
Fiscal 1996 Compared to Fiscal 1995
 
Results of Operations
 
     Total Revenues.  Revenues increased by 41.8% from $11.5 million in fiscal
1995 to $16.3 million in fiscal 1996. Product sales increased by 30.6% from $7.6
million in fiscal 1995 to $9.9 million in fiscal 1996 primarily due to the
introduction of NACT's new STX switching system in May 1996. Network carrier
sales increased by 36.0% from $2.8 million in fiscal 1995 to $3.8 million in
fiscal 1996 due to increased carrier usage volumes from existing network carrier
customers. Wins generated $1.1 million in revenues in fiscal 1995. Revenues
generated from Wins network carrier sales in fiscal 1996 were $2.6 million.
 
Gross Profit
 
     Product Sales.  Gross profit on product sales increased 20.8% from $5.0
million in fiscal 1995 to $6.0 million in fiscal 1996 due to an increase in
product sales resulting from the introduction of the STX in May 1996. Gross
profit on product sales as a percentage of product sales decreased from 65.2% in
fiscal 1995 to 60.3% in fiscal 1996 primarily due to lower margins resulting
from an emphasis on promoting the STX. Margins on initial STX sales were lower
due to special STX upgrade pricing provided to NACT's current customers through
June 1, 1996.
 
     Network Carrier Sales.  Gross profit on network carrier sales increased
from $0.1 million in fiscal 1995 to $0.4 million in fiscal 1996 due to increased
network carrier sales volume. Gross profit on network carrier sales as a
percentage of network carrier sales increased from 1.8% in fiscal 1995 to 10.6%
in fiscal 1996 due to increased volume discounts received from the underlying
carriers as a result of increased network carrier usage. NACT began its network
carrier operations in fiscal 1995.
 
     Wins.  Wins generated $0.3 million of gross profit in fiscal 1995 or 28.3%
of Wins sales. NACT transferred ownership and operations of Wins to GST USA on
October 1, 1995 and provided carrier services at cost to GST USA for the Wins
operations in fiscal 1996.
 
     Overall.  Gross profit increased 23.6% from $4.9 million in fiscal 1995 to
$6.0 million in fiscal 1996 due to an increase in both product and network
carrier sales volume. Gross profit as a percentage of net revenues
 
                                       99
<PAGE>   111
 
decreased from 42.5% in fiscal 1995 to 37.0% in fiscal 1996 primarily due to
lower margins resulting from an emphasis on the STX switching system and lower
margins on initial sales of the STX switching systems.
 
     Research and Development.  Research and development expenses increased by
14.3% from $1.2 million in fiscal 1995 to $1.4 million in fiscal 1996 primarily
due to the move to more rapidly develop the STX switching system and to maintain
ongoing research and development of NACT's existing hardware and software
product lines. NACT's capitalized software development costs were $0.2 million
and $0.4 million in fiscal 1995 and 1996, respectively.
 
     Selling and Marketing.  Selling and marketing expenses increased 3.1% from
$0.9 million in fiscal 1995 to $1.0 million in fiscal 1996 primarily due to
continued expansion of NACT's sales and marketing staff. Fiscal 1996 selling and
marketing expenses were offset by the transfer of certain salary and fringe
benefit expenses to general and administrative when the Director of Sales and
Marketing was promoted to Executive Vice President and then to President and
Chief Executive Officer.
 
     General and Administrative.  General and administrative expenses increased
by 40.5% from $2.2 million in fiscal 1995 to $3.0 million in fiscal 1996
primarily due to an increase in the provision for bad debt, continued expansion
of the manufacturing and technical support departments, the expansion of the
finance department and implementation of a company-wide quality assurance
program. The increase in the provision for bad debt was a result of increased
sales volume and the addition of a $310,000 reserve for accounts receivable due
from Overseas Telecom (a network carrier customer), which was transferred to a
note receivable.
 
     Income Taxes.  NACT recorded provisions for income taxes with effective
rates of 71.9% and 28.8% of income before taxes for fiscal 1995 and 1996,
respectively. The decrease in the effective tax rate is a result of additional
amortization of goodwill, which is not deductible for income tax purposes.
Future effective tax rates are expected to be in excess of statutory rates
during the amortization period of the acquired goodwill from GST USA because the
goodwill is not deductible for tax purposes.
 
Three Months Ended December 31, 1997 Compared to Three Months Ended December 31,
1996
 
Results of Operations
 
     Total Revenues.  NACT's revenues increased 35.9% from $6.4 million for the
three months ended December 31, 1996 to $8.7 million in the equivalent 1997
quarter. Product sales, which include switching application systems, software
and factory support, increased 52.7% from $4.8 million for the three months
ended December 31, 1996 to $7.3 million in the equivalent 1997 quarter,
primarily due to sales of STX and NTS switching and billing systems into the
international market and sales of larger port capacity STX switches. Network
carrier sales decreased 13.9% from $1.6 million for the three months ended
December 31, 1996 to $1.4 million in the equivalent 1997 quarter primarily due
to decreased carrier usage volumes from existing network carrier customers.
 
Gross Profit
 
     Product Sales.  NACT's gross profit increased 65.1% from $3.0 million for
the three months ended December 31, 1996 to $5.0 million in the equivalent 1997
quarter due to an increase in product sales resulting from sales of the higher
margin, larger port capacity STX switches. Gross profit on product sales as a
percent of product sales was 63.8% and 70.4% for the three months ended December
31, 1996 and 1997, respectively.
 
     Network Carrier Sales.  NACT's gross profit decreased 100.0% from $52,000
for the three months ended December 31, 1996 to $0 in the equivalent 1997
quarter primarily due to a decrease in network carrier sales and higher carrier
usage costs from NACT's long distance carriers. Gross profit on network carrier
sales as a percent of network carrier sales was 3.2% and 0.0% for the three
months ended December 31, 1996 and 1997, respectively.
 
     Research and Development.  NACT's research and development expenses
increased 88.9% from $423,000 for the three months ended December 31, 1996 to
$799,000 in the equivalent 1997 quarter. The increase is primarily due to an
increase in personnel and other expenditures for completion of several hardware
 
                                       100
<PAGE>   112
 
and software research and development projects designed to enhance the STX
switching platform and upgrade the NTS billing system to a new hardware and
software platform. Capitalized software development costs were approximately
$125,000 and $187,000 for the three months ended December 31, 1996 and 1997,
respectively.
 
     Sales and Marketing.  NACT's sales and marketing expenses increased 114.8%
from $357,000 for the three months ended December 31, 1996 to $767,000 in the
equivalent 1997 quarter primarily due to the hiring of additional sales
personnel, the opening of new domestic sales offices, increased advertising and
trade show expenditures, and increased commissions paid as a result of the
increase in product sales.
 
     General and Administrative.  NACT's general and administrative expenses
increased 62.9% from $836,000 for the three months ended December 31, 1996 to
$1,362,000 in the equivalent 1997 quarter primarily due to the hiring of new
finance, technical support, training and facilities management personnel to
support NACT's increased sales, shipments and installations of STX switching and
NTS billing systems, and the additional overhead expenses of NACT's new
headquarters/manufacturing facility which was completed on July 1, 1997.
 
     Amortization of Acquired Intangibles.  NACT has included amortization of
acquired intangibles as a component of both cost of sales and operating
expenses. These intangibles arose as a result of the acquisition of NACT by GST
USA through a series of purchases of newly issued shares and shares owned by
former stockholders of NACT. Such purchases occurred from September 1993 through
December 1994. GST USA accounted for the acquisition using the purchase method
of accounting. The excess of the purchase price over the fair value of the
assets acquired was assigned by GST USA as product support contracts, software
development costs and goodwill and, in accordance with requirements of the
Commission, has been included in the balance sheet of NACT with related
amortization recorded in cost of goods sold and other operating expenses.
Product support contracts and software development costs are being amortized
over a five year straight-line period and goodwill is being amortized over a 20
year straight-line period. In addition, NACT acquired the customer list of its
Eastern Europe network carrier customer in September 1997. This customer list
was recorded on NACT's books at the lower of fair market value or cost as an
intangible asset and is being amortized to cost of sales over a three year
period.
 
     Income Taxes.  NACT's effective tax rate for the three months ended
December 31, 1997 was 40.0%. This is higher than the respective statutory
federal and state tax rates due to amortization of goodwill. This higher
effective tax rate is expected to continue during the amortization period of the
acquired goodwill from GST USA.
 
     Fluctuations in Quarterly Operating Results.  Operating results have in the
past fluctuated and may in the future fluctuate due to factors such as the
timing of new product introductions by NACT and its competitors, delays in new
product introductions by NACT, market acceptance of new or enhanced versions of
NACT's products, changes in the product or customer mix, changes in the level of
operating expenses, competitive pricing pressures, the gain or loss of
significant customers, increased research and development and sales and
marketing expenses associated with new product introductions and economic
conditions in general and in NACT's industry. Due to the high unit price and
long lead times associated with revenues derived from equipment orders, NACT's
financial results may fluctuate significantly depending upon the time of the
actual shipment of such orders. All of the above factors are difficult for NACT
to forecast, and these or other factors can materially adversely affect NACT's
business, financial condition and results of operations for one quarter or a
series of quarters. NACT's expense levels are based in part on its expectations
regarding future sales and are fixed in the short term to a large extent.
Therefore, NACT may be unable to adjust spending in a timely manner to
compensate for any unexpected shortfall in sales. Any significant decline in
demand relative to NACT's expectations or any material delay of customer orders
could have a material adverse effect on NACT's business, financial condition and
results of operations.

systems, software, consulting, and factory support, increased 68.7% from $5.7
million for the three months ended June 30, 1997 to $9.7 million in the
equivalent 1998 quarter primarily due to sales of larger port capacity STX
switches and NTS billing systems to new and existing customers and STX
application system upgrades to existing customers. Network carrier sales
decreased 51.2% from $1.5 million for the three months ended June 30, 1997 to
$0.7 million in the equivalent 1998 quarter primarily due to one customer moving
a substantial portion of network carrier traffic to another carrier.

Gross Profit
 
     Product Sales.  NACT's gross profit increased 61.8% from $4.3 million for
the three months ended June 30, 1997 to $6.9 million in the equivalent 1998
quarter due to an increase in product sales resulting from sales of the higher
margin, larger port capacity STX switches and lower manufacturing costs per

for the three months ended June 30, 1997 to $94,000 in the equivalent 1998
quarter, primarily due to lower network carrier rates paid by NACT. Gross profit
on network carrier sales as a percent of network carrier sales was 5.3% and
13.1% for the three months ended June 30, 1997 and 1998, respectively.
 
     NACT's gross profit increased 86.2% from $138,000 for the six months ended
June 30, 1997 to $257,000 in the equivalent 1998 period primarily due to lower
network carrier rates paid by NACT. Gross profit on network carrier sales as a
percent of network carrier sales was 5.1% and 10.6% for the six months ended
June 30, 1997 and 1998, respectively.
 
     Research and Development.  NACT's research and development expenses
increased 2.2% from $740,000 for the three months ended June 30, 1997 to
$756,000 in the equivalent 1998 quarter primarily due to an increase in
expenditures for planning, design, and completion of several hardware and
software research and development projects designed to enhance the STX switching
platform and introduce a new billing system. Capitalized software development
costs were $212,000 and $271,000 for the three months ended June 30, 1997 and
1998, respectively.
 
     NACT's research and development expenses increased 10.3% from $1.4 million
for the six months ended June 30, 1997 to $1.5 million in the equivalent 1998
period primarily due to an increase in personnel and other expenditures for
planning, design, and completion of several hardware and software research and
development
 
                                       102

projects. Capitalized software development costs were $629,000 and $480,000 for
the six months ended June 30, 1997 and 1998, respectively.
 
     Sales and Marketing.  NACT's sales and marketing expenses increased 8.6%
from $824,000 for the three months ended June 30, 1997 to $895,000 in the
equivalent 1998 quarter primarily due to increased advertising and trade show
expenditures, and increased commissions paid as a result of the increase in
product sales.
 
     NACT's sales and marketing expenses increased 25.1% from $1.4 million for
the six months ended June 30, 1997 to $1.7 million in the equivalent 1998 period
primarily due to the hiring of additional senior sales personnel, international
marketing and selling efforts, increased advertising and trade show
expenditures, and increased commissions paid as a result of the increase in
product sales.
 
     General and Administrative.  NACT's general and administrative expenses
increased 16.4% from $891,000 for the three months ended June 30, 1997 to
$1,037,000 in the equivalent 1998 quarter primarily due to increased legal
expenses related to the patent infringement lawsuit.
 
     NACT's general and administrative expenses increased 40.6% from $1.6
million for the six months ended June 30, 1997 to $2.3 million in the equivalent
1998 period primarily due to increased legal expenses related to the patent
infringement lawsuit, accounting, and investment banking expenses related to the
NACT Stock Purchase Agreement and the NACT Merger Agreement.
 
     Amortization of Acquired Intangibles.  NACT has included amortization of
acquired intangibles as a component of both cost of sales and operating
expenses. These intangibles arose as a result of the acquisition of NACT by GST
USA through a series of purchases of newly issued shares and shares owned by
former stockholders of NACT. Such purchases occurred from September 1993 through
December 1994. GST USA accounted for the acquisition using the purchase method
of accounting. The excess of the purchase price over the fair value of the
assets acquired, was assigned by GST USA as product support contracts, software
development costs and goodwill. In accordance with requirements of the SEC,
these amounts have been included in the balance sheets of NACT with related
amortization recorded in cost of goods sold and other operating expenses.
Product support contracts and software development costs are being amortized
over a five year straight-line period. Goodwill is being amortized over a 20
year straight-line period. In addition, NACT acquired the customer list of its
Eastern Europe network carrier customer in September 1997. This customer list
was recorded on NACT's books at the lower of fair market value or cost as an
intangible asset, and is being amortized to cost of sales over a three-year
period.
 
     Income Taxes.  NACT's effective tax rate for the six months ended June 30,
1998 was 40.0%. This is higher than the respective statutory federal and state
tax rates due to amortization of goodwill. This higher effective tax rate is
expected to continue during the amortization period of the acquired goodwill
from GST USA.
 
     Fluctuations in quarterly operating results.  Operating results have in the
past and may in the future fluctuate due to factors such as the timing of new
product introductions by NACT and its competitors, delays in new product
introductions by NACT, market acceptance of new or enhanced versions of NACT's
products, changes in the product or customer mix, changes in the level of
operating expenses, competitive pricing pressures, the gain or loss of
significant customers, increased research and development and sales and
marketing expenses associated with new product introductions and economic
conditions in general and in NACT's industry. Due to the high unit price and
long lead times associated with revenues derived from equipment orders, NACT's
financial results may fluctuate significantly depending upon the time of the
actual shipment of such orders. All of the above factors are difficult for NACT
to forecast, and these or other factors can materially adversely affect NACT's
business,financial condition and results of operations for one quarter or a
series of quarters. NACT's expense levels are based in part on its expectations
regarding future sales and are fixed in the short term to a large extent.
Therefore, NACT may be unable to adjust spending in a timely manner to
compensate for any unexpected shortfall in sales. Any significant decline in
demand relative to NACT's expectations or any material delay of customer orders
could have a material adverse effect on NACT's business, financial condition and
results of operations.

Liquidity and Capital Resources
 
     NACT currently finances its operations, and normal reoccurring capital
expenditures through cash flow from operations and its current cash and
short-term investment balances. For the six months ended June 30, 1998,
operating activities provided cash of $3.2 million.
 
     As of June 30, 1998, NACT had cash, cash equivalents and marketable
securities totaling $14.8 million an increase of $2.3 million from December 31,
1997 primarily due to an increase in cash flow from operations.
 
     NACT maintains an unsecured bank line of credit expiring in February 1999
that provides borrowings up to $1.0 million at the bank's prime rate plus one
point. There were no outstanding draws under the line of credit as of June 30,
1998.
 
     NACT acts as a guarantor on financing of some customer transactions
executed under repurchase agreements with two financial institutions. In
accordance with the terms of one of the repurchase agreements, NACT maintains a
$6.0 million unrestricted cash balance. As of June 30, 1998, NACT was
contingently liable under these repurchase agreements for approximately $7.6
million.
 
     NACT believes that the June 30, 1998 cash and marketable securities
balances, anticipated cash flows from operations and its line of credit will
satisfy NACT's working capital and capital expenditure requirements for at least
the next twelve months. However, there can be no assurance that NACT will not be
required to seek additional capital sooner or, if so required, that adequate
capital will be available on terms acceptable to NACT, or at all.
 
Year 2000
 
     NACT currently sells the NTS 1000 billing system which will require
upgrading by the year 2000 due to its existing limitation of using only two
digits to identify the year in the date field. NACT is planning release of its
new billing system, the NTS 2000, by the first calendar quarter of 1999, which
overcomes the two digit limitation currently experienced on the NTS 1000.
Furthermore, NACT is in the process of modifying the NTS 1000 software to
overcome the two digit limitation. This modification of the NTS 1000 software is
anticipated to be completed by the first calendar quarter in 1999 at an
estimated cost of $115,000. NACT anticipates the majority of customers will
upgrade to the NTS 2000. No assurance can be made that any of NACT's customers
will upgrade to the NTS 2000 or that the modification to the NCT 1000 software
will be successful or competed on time. In the event that a significant number
of NACT's customers do not upgrade to the NTS 2000 or the NTS 1000 software
modification is not successful, NACT may incur expenses and potential loss of
ongoing service revenues.
 
     In addition, NACT is in the process of evaluating its computer systems to
determine what modifications (if any) are necessary to make such systems
compatible with the year 2000 requirements. However, because many of NACT's
computer systems have been put into service within the last several years, NACT
does not expect any such modifications to have a material adverse effect on
NACT's financial position or results of operations. There can be no assurance,
however, that the computer systems of other companies on which NACT's systems
rely will be timely modified, or that a failure to modify such systems by
another company, or modifications that are incompatible with NACT's systems,
would not have a material adverse effect on NACT.

EXECUTIVE COMPENSATION
 
     Compensation of Directors.  Non-employee directors of World Access receive
no cash compensation from World Access for their service as directors. Their
compensation is in the form of stock warrants as discussed below. The directors
are reimbursed for out-of-pocket travel and related expenses incurred in
connection with their attendance at meetings of the board of directors or its
committees and at other company events to which they are invited.
 
     In December 1994, in an effort to attract and retain experienced executives
to serve as outside directors for World Access, the board of directors adopted
the World Access, Inc. Outside Directors' Warrant Plan (the "Warrant Plan"). The
stockholders of World Access approved the Warrant Plan at the 1995 Annual
Meeting of Stockholders.
 
     The purposes of the Warrant Plan are to attract and retain the best
available personnel for service as directors of World Access, to provide
additional incentive to the persons serving as directors of World Access, to
align director and stockholder long-term interests and to encourage continued
service on the board of directors. Warrants may be granted under the Warrant
Plan only to directors of World Access who are neither employees of World Access
nor of any of its affiliates. The aggregate number of shares of World Access
Common Stock authorized to be issued pursuant to the Warrant Plan is 1,200,000,
subject to adjustment in certain instances as described below. The Warrant Plan
provides that each eligible non-employee director elected to serve as a director
of World Access on or after October 1, 1994 may be granted, in the discretion of
the board of directors, warrants to purchase no more than 450,000 shares of
World Access Common stock in the aggregate. The initial exercise price of the
warrants will be not less than the fair market value of the Common Stock subject
to the warrant on the date of grant.
 
     In December 1994, three new outside directors of World Access, Messrs.
O'Reilly, Phillips and Raville, each received warrants entitling him to purchase
150,000 shares of World Access Common Stock on or prior to December 15, 1999.
These warrants, now fully vested, are exercisable at a price of $1.50 per share
with respect to 50,000 shares, $2.25 per share with respect to 50,000 shares and
$4.00 per share with respect to 50,000 shares. At the time these warrants were
granted, the fair market value of the World Access Common Stock was $1.25 per
share. During 1997, Mr. O'Reilly and Mr. Phillips exercised 150,000 and 50,000
warrants, respectively, and Mr. Phillips donated 32,660 warrants to charitable
organizations. During 1998, Mr. Raville exercised 150,000 warrants.
 
     Concurrent with the above initial grant, Mr. Clearman, the fourth outside
director of World Access, was awarded warrants to purchase 126,000 shares of
World Access Common Stock. The terms of this grant were identical to those
described above except the number of shares exercisable at the $1.50 exercise
price was set at 26,000 instead of 50,000. During 1997, Mr. Clearman exercised
all of these warrants.
 
     In December 1994, the board of directors awarded Steven A. Odom, who joined
the board of directors in October 1994 and became Chairman in November 1994,
warrants under the Warrant Plan to purchase 450,000 shares of World Access
Common Stock. The warrants, now fully vested, entitle Mr. Odom to purchase
450,000 shares of World Access Common Stock on or prior to December 15, 1999 at
an exercise price of $1.50 per share with respect to 150,000 shares, $2.25 per
share with respect to 150,000 shares and $4.00 per share with respect to 150,000
shares. During 1997, Mr. Odom exercised 150,000 of these warrants. During 1998,
Mr. Odom exercised the remaining 300,000 warrants.
 
     In December 1994, the board of directors also adopted the Directors'
Warrant Incentive Plan (the "Incentive Plan") pursuant to which the board of
directors may grant, beginning in February 1997, to each non-employee director
on an annual basis warrants to purchase up to 50,000 shares of World Access
Common Stock at an exercise price per share equal to no less than 110% of the
fair market value of the stock at the date of grant. No warrants may be granted
under the Incentive Plan in a given year unless World Access Common Stock has
appreciated by a compounded annual average rate of return in excess of 35% for
the four year period preceding the year of grant. The aggregate number of shares
of World Access Common Stock authorized to be issued pursuant to the Incentive
Plan is 600,000 subject to adjustment in certain instances as described below.
 
                                       107
<PAGE>   119
 
     Warrants granted under the Warrant Plan and the Incentive Plan become
exercisable in one or more installments, as the board of directors may
determine, six months and one day after the date of the grant and expire on the
fifth anniversary following the date of grant, provided that if the Director has
not attended at least 75% of the meetings of the board of directors for the year
in which an installment first becomes exercisable, then such installment may not
be exercised.
 
     On March 26, 1997, the board of directors granted the four outside
Directors of World Access warrants to each purchase 50,000 shares of World
Access Common Stock with an exercise price of $9.21. These warrants became fully
vested and exercisable on December 31, 1997. During 1998, Mr. O'Reilly and Mr.
Raville each exercised 50,000 warrants.
 
     On February 27, 1998, the board of directors granted the four outside
directors of World Access warrants to each purchase 50,000 shares of Common
Stock with an exercise price of $25.85. The warrants granted to Mr. O'Reilly
were forfeited upon his resignation. The remaining 150,000 warrants will be
exercisable on or after December 31, 1998 provided that the Director attends at
least 75% of the Board and Applicable Committee meetings held during 1998.
 
     Notwithstanding the foregoing, the Warrant Plan and the Incentive Plan
provide that warrants awarded pursuant to these plans will become immediately
exercisable (i) if World Access is to be consolidated with or acquired by
another entity in a merger, (ii) upon the sale of substantially all of World
Access assets or the sale of at least 90% of the outstanding World Access Common
Stock to a third party, (iii) upon the merger or consolidation of World Access
with or into any other corporation or the merger or consolidation of any
corporation with or into World Access (in which consolidation or merger the
stockholders of World Access receive distributions of cash or securities as a
result thereof), or (iv) upon the liquidation or dissolution of World Access.
The Merger does not constitute a change of control for purposes of the Warrant
Plan or the Incentive Plan.

(1) Long-Term Compensation Awards for 1997 include non-qualified stock options
    granted in December 1997 from the World Access 1998 Incentive Equity Plan.
    The securities underlying options for 1997 under this grant include: Mr.
    Odom -- 400,000 shares; Mr. West -- 300,000 shares; and Mr.
    Gergel -- 200,000 shares. These options, which are subject to stockholder
    approval, vest 25% on each of the first four anniversaries from the date of
    grant and are exercisable at $19.00 per share, the market price as of the
    date of grant. The date the stockholders approve the 1998 Incentive Equity
    Plan will become the measurement date for purposes of computing compensation
    expense, if any. If the stock price as of the measurement date exceeds
    $19.00, then the total compensation impact will be the difference between
    the stock price at the measurement date and $19.00. World Access will record
    that expense ratably over a period of four years.
    In connection with voluntary salary reduction/incentive programs in 1996 and
    1995, which were offered to all salaried employees of World Access, the
    Named Executives elected to forego salary in exchange for options to
    purchase shares of World Access Common Stock at the then current market
    prices of $8.00 and $7.00 per share, respectively. The securities underlying
    options for 1996 for this program include: Mr. Odom -- 55,000 shares; Mr.
    West -- 48,125 shares; Mr. Gergel -- 37,500 shares; and Mr.
    Madigan -- 10,000 shares. The securities underlying options for 1995 for
    this program include: Mr. Odom -- 50,000 shares; Mr. West -- 43,750 shares;
    Mr. Gergel -- 24,000 shares; and Mr. Madigan -- 10,000 shares. Stock options
    issued in connection with these programs are now fully vested.
(2) Mr. Odom joined the World Access board of directors in October 1994 and was
    elected Chairman in November 1994. He was appointed Chairman and Chief
    Executive Officer in August 1995. Mr. Odom elected to not receive a salary
    in 1995. In December 1995, he was awarded non-qualified stock options to
    acquire 200,000 shares of World Access Common Stock at $7.00 per share, the
    then current market price. These options vested 50% on each of the first two
    anniversaries from the date of grant.
(3) Mr. West joined World Access in January 1996 as its new President and Chief
    Operating Officer. In August 1995, in connection with his acceptance of the
    World Access offer of employment, he was awarded non-qualified stock options
    to acquire 400,000 shares of World Access Common Stock at $3.78 per share,
    the then current market price. These options vest 25% on each of the first
    four anniversaries from his effective date of employment.
(4) Mr. Madigan joined World Access in March 1996 as its new Vice President of
    Business Development. He was awarded non-qualified stock options to acquire
    80,000 shares of World Access Common Stock at $7.81 per share, the then
    current market price. These options vest 25% on each of the first four
    anniversaries from the date of grant.
(5) Mr. Graham joined World Access in March 1997 as its new President, Transport
    and Access Systems Group. He was awarded non-qualified stock options to

    then current market price. These options vest 25% on each of the first four
    anniversaries from the date of grant.
(6) During 1997, Mr. Gergel was paid a flat sum allowance of $25,000 and during
    1996, Mr. West and Mr. Madigan were paid flat sum allowances of $35,000 and
    $20,000, respectively, for the relocation of their households to Atlanta,
    Georgia.
(7) During 1997, Mr. West was paid $7,000 for life insurance benefits provided
    to him by World Access.
(8) Except as noted above, All Other Compensation represents matching
    contributions by World Access under its 401(k) Plan.

table sets forth information concerning the value of director warrants and
employee options exercised by the Named Executives during 1997 and the value at
December 31, 1997 of unexercised warrants and options held by each such officer.

     Severance Protection Agreements.  World Access entered into a Severance
Protection Agreement with each of Messrs. Odom, West and Gergel (each an
"Executive") as of November 1, 1997 (the "Severance Agreements"). Each Severance
Agreement is effective for an initial term of two years and is automatically
renewed for additional consecutive one-year terms unless timely notice of
non-renewal is given by either World Access or the Executive. Generally, each
Severance Agreement provides that if the Executive's employment is terminated
within 12 months after a "change of control" (as defined in the Severance
Agreement) (i) by World Access other than for "cause" (as defined in the
Severance Agreement), or (ii) by the Executive for "good reason" (as defined in
the Severance Agreement), the Executive is entitled to a lump sum payment equal
to the sum of (a) accrued and unpaid salary, expenses, vacation pay and bonuses,
(b) two times the Executive's annual base salary and bonus and (c) the excess of
the actuarial equivalent of retirement benefits to which the Executive would be
entitled under World Access's supplemental and other retirement plans had the
Executive remained in the employ of World Access for an additional two years of
credited service over the actual actuarial equivalent benefits to which the
Executive is entitled under such plans. In addition, upon any such termination
World Access is obligated to continue, at its expense, for a 24 month period the
medical, disability and life insurance benefits enjoyed by the Executive prior
to termination, to provide the Executive with outplacement services, reasonable
office space and secretarial assistance, and the restrictions on outstanding
stock options and similar incentive awards lapse and such options and awards
become immediately vested and exercisable to the extent that they would have
been vested and exercisable within two years of the date of the Executive's
termination. Payments under the Severance Agreements are subject to limitations
to the extent they would be subject to an excise tax imposed under the Code or
would not be deductible by World Access.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
     In October 1997, Mr. Phillips, a director of World Access, entered into a
series of agreements whereby, among other things, he became the new chairman and
chief executive officer of Resurgens. Resurgens was shortly thereafter placed
into bankruptcy under Chapter 11 of the United States Bankruptcy Code. WorldCom,
a major customer and vendor of Resurgens, subsequently agreed to provide
Resurgens up to $28 million in financing in the form of a debtor in possession
facility and other credits.
 
     During the fourth quarter of 1997, World Access shipped switching equipment
to Resurgens. The cost of this equipment was approximately $3.8 million. On
February 12, 1998, World Access executed a letter of intent to acquire
Resurgens. The equipment shipped to Resurgens is included in World Access
inventory at December 31, 1997. During the second quarter of 1998, this
switching equipment was returned to World Access.
 
     In April 1998, the Company purchased approximately $3.6 million of
switching equipment which has been consigned to Resurgens. Upon its acquisition
of Resurgens, the Company will account for this equipment as part of its
investment in Resurgens. If the acquisition is not consummated, the Company
expects to negotiate an arms-length sale of the equipment to Resurgens or
another customer. This equipment is included in Other assets on World Aceess'
June 30, 1998 balance sheet.
 
     See "Summary -- The Merger -- Recent World Access Developments" for a
description of the Resurgens Transaction.

                                 TELCO SYSTEMS
 
BUSINESS
 
     General. Telco Systems was incorporated in California on September 7, 1972,
and reincorporated in Delaware on December 17, 1986. Its principal office is
located at 63 Nahatan Street, Norwood, Massachusetts 02062 (telephone number is
(781) 551-0300). Telco Systems is a supplier of three major product lines,
focused on providing integrated access for network services: the broadband
transmission products, referred to as "Broadband"; the network access products,
referred to as "Access"; and the bandwidth optimization products, referred to as
"Bandwidth Optimization".
 
     Telco Systems' products are deployed at the edge of the service providers'
networks to provide organizations with a flexible, cost-effective means of
transmitting voice, data and video traffic over public or private networks.
These products are used in a wide variety of applications by network service
providers, such as long distance carriers, RBOCs, independent and competitive
local exchange providers ("CLEC"), as well as government agencies, electric
utilities, wireless service operators, and major corporations. Its products,
which can be found most often in telephone company central offices and in
private communications networks, perform functions that range from basic
signaling and multiplexing of DS0 (64kbps) low speed data and voice traffic to
digital fiber optic transmission of high-speed, high-capacity services over
SONET OC-3 (155Mbps) networks.
 
     In January 1983, Telco Systems acquired the fiber optics transmission
business from Raytheon Company, which evolved into the Broadband product line.
Sales of broadband transmission products in fiscal year 1998 comprised
approximately 52% of Telco Systems' total revenue. In August 1984, Telco Systems
acquired TeleBit, Inc., a manufacturer of digital transmission systems based in
Lombard, Illinois. Later, the products from this acquisition were merged with
Telco Systems' Voice Frequency products which together evolved into the Access
product line. In fiscal 1998, sales of access products were 45% of total sales.
In May 1992, Telco Systems acquired Magnalink Communications Corporation, a
developer and manufacturer of high speed data compression and bandwidth
optimization products, which evolved into the Bandwidth Optimization product
line. In fiscal 1998, bandwidth optimization products represented 3% of sales.
 
     In January 1998, Telco Systems acquired Jupiter Technology, Inc. This
acquisition brought frame relay and asynchronous transfer mode (ATM) technology
to enhance the features and interfaces available in the Telco Systems' product
portfolio.
 
     Telco Systems has continued to focus on and grow its revenues in the access
market, while reducing its costs of doing business in that highly competitive
market over the last four quarters.
 
     In the second quarter of fiscal year 1998, Telco Systems introduced its
EdgeLink 100 product which aggregates and consolidates traffic from various T1
lines over a more cost-effective T3 line. This product is marketed to major
carriers as well as competitive local exchange providers interested in reducing
their cost of access and delivery of services to customers.
 
     On October 26, 1998, Telco Systems acquired Synaptyx, a developer of
integrated access solutions focusing on new service providers in the local loop
services market. The Synaptyx product is a next generation integrated access
device for bundled IP (Internet Protocol), Frame Relay and TDM (Time Division
Multiplexer) services.
 
     For fiscal 1998, Telco Systems reported sales of $113.2 million and a net
loss of $3.3 million or $.30 per share. The net loss included a charge for the
write off of in-process technology in connection with the acquisition of Jupiter
Technology of $5.1 million or $.47 per share. Working capital at year end
amounted to $39.7 million, including cash and marketable securities of $21.0
million. For a more complete discussion of the results of operations, please
refer to " -- Management Discussion and Analysis of Results of Operations and
Financial Condition" below.
 
     Broadband Products. Primary customers of Telco Systems' Broadband products
are RBOCs and major independent telephone companies as well as competitive and
alternate access providers. Products are sold as
 
                                       114
<PAGE>   126
 
either complete systems or as stand-alone equipment installed by Telco Systems,
third party installers, or by Telco Systems' customers. A complete system may
include the fiber optic cable, which is not manufactured by Telco Systems but is
purchased from a number of suppliers.
 
     The most common application of Telco Systems' Broadband transmission
products is for cost-effective delivery of high capacity T1 (1.544Mbps) and T3
(45Mbps) services in the local loop applications between the telephone company
central office or hubbing sites and customers' business premises. These services
are delivered over both fiber optic technology, as well as copper-based
technology. Telco Systems believes that such local loop applications will
continue to grow due to the Telecommunications Reform Act of 1996 as the local
access market opens to competition.
 
     Fiber Optic Terminals and Multiplexers:  These systems typically consist of
a digital multiplexer and a fiber optic transmitter/receiver integrated into one
functional unit. The multiplexer portion of the terminal unit combines digital
inputs from multiple sources into one digital output. Multiplexers can be
combined in order to achieve higher transmission rates. The basic function of
the transmitter portion of a terminal is to convert electronic input into a
series of light pulses for transmission over optical fiber. The receiver
function of a terminal reconverts the light pulses received over the fiber into
digital electronic signals. To meet the various needs of the public and private
telephone networks, Telco Systems offers products for transmitting at different
capacities.
 
     Telco Systems offers modular fiber optic terminals that enable the customer
to upgrade its system by adding modules as increased capacity is required. Telco
Systems' terminals, depending on bit-rate and other design configurations, can
accommodate transmission over distances of up to 60 kilometers. Prices for a
typical system are dependent on configuration and accordingly can range from
$5,000 to $30,000 per terminal.
 
     The broadband transmission multiplexers support speeds ranging from T1
(1.544Mbps) to SONET OC3 (155Mbps). These systems can connect into asynchronous
or SONET digital cross-connect systems in a service provider's central office.
 
     Access Products. Primary customers of Telco Systems' access products are
long distance service providers, competitive and alternate local access
providers, RBOCs, government agencies, electric utilities and wireless service
operators. In many cases, the products are purchased by the service providers
and are installed on customer premises or are leased to private network users.
These products comply with both North American and international standards for
specific applications, and are sold worldwide.
 
     Telco Systems' network access products are designed for the digital
multiplexing of voice and data traffic of up to T1 and E1 rates. The trend
towards increased use of public network services for voice, data and video
applications has created greater demand for customer premises access
multiplexers. Telco Systems' access servers enable integration of multiple
slower-speed lines and services onto a single or multiple, high-speed, T1/E1
access facility, ultimately saving access line charges for end users. They
support interfaces for various types of telephony and data services, such as
Plain Old Telephone Service (POTS), Centrex extensions, P-Phones, switched data,
Integrated Services Digital Network (ISDN) and frame relay. In addition, Telco
Systems provides a network management system which is designed to control its
intelligent transmission products.
 
     Typical prices for network access equipment range from $5,000 to $15,000.
 
     Network Access Servers:  Telco Systems' Access45 and Access60 network
access servers provide highly reliable digital access to public, private and
hybrid networks. They integrate multiple business applications through
cost-effective connections to dedicated, switched and packet network services,
and support multiple networking functions such as T1/E1 add/drop multiplexing,
grooming and digital cross-connection. They also support advanced services such
as ISDN and frame relay. The products provide complete redundant architecture
for fail-safe operation, a must for service providers. Access45 was introduced
during fiscal 1997, and is a smaller version of Access60 representing a lower
price point. It is designed to meet a key requirement for the CLEC marketplace,
which is to provide a high number of service ports in a very small form factor.
It is completely compatible with Access60, and uses the same interface cards to
deliver the same services.

     Digital Multiplexer Products:  Telco Systems' products use digital
technology and provide over 40 different plug-in printed circuit cards to
support a large variety of analog and digital voice, data, and video
applications. The products provide conversion of analog signals into digital
information, combine them with additional digital data inputs and enable them to
be processed and transmitted at high speed over copper wires. Telco Systems
provides a full range of products from cost effective digital channel banks to
high-functionality DSU/CSU.
 
     Network Management and Control System:  Telco Systems offers a
standards-based SNMP network management system, the MVX. This system is designed
to control all major products in the Telco Systems portfolio. This system
remotely manages voice and data mix, bandwidth allocation, and selective access
to special services offered by T1 carriers. In addition, it can be used to
modify the network as user requirements change.
 
     Bandwidth Optimization Products.  Primary customers for Telco Systems'
Bandwidth Optimization products are private network users at major corporations
worldwide. These products interconnect geographically remote local area networks
(LANs) through wide area networks (WANs), with an emphasis on optimizing the
utilization of WAN links. In LAN/WAN applications, WAN links have the lowest
throughput, the highest expense, the lowest reliability, and the least security.
The Bandwidth Optimization products increase the throughput of WAN links by two
to six times (depending on the type of data traffic) via data compression;
reduce expense of WAN links by enabling usage of lower-speed links at higher
throughput; and offer features for improved redundancy, fault tolerance,
security and privacy. Typical units are in the $3,000 to $9,000 price range. The
Optimizer product line also supports compression for frame relay data, and can
be connected to any standard frame relay service offering. It is approved in the
leading frame relay service offerings, such as AT&T, WorldCom and Sprint.
 
     Marketing and Customers.  Telco Systems is engaged in a single business
segment constituting the development, manufacturing, marketing and service of
integrated access solutions for the telecommunications industry. Primary users
of Telco Systems' products are the RBOCs, independent telephone companies,
interexchange carriers, competitive and alternate access providers, electric
utilities, wireless service operators, government agencies and private network
end users.
 
     Telco Systems' broadband transmission products and network access products
are generally sold to specialized common carriers and telephone operating
companies on an off-the-shelf basis. Typically, the products have been evaluated
by such customers and approved for purchase in advance. Both network access and
broadband products are manufactured by Telco Systems based on forecasted usage.
Sales to the RBOCs accounted for 41% of sales in fiscal 1998, 39% of sales in
fiscal 1997 and 37% of sales in fiscal 1996. RBOC sales include sales to Bell
Atlantic of 36% of total Telco Systems in fiscal 1998, 33% in fiscal 1997 and
31% in fiscal 1996. Bell Atlantic continues to be a significant customer of the
Broadband Business Unit. If Bell Atlantic and GTE complete their contemplated
merger, the combined entity will become a large customer of Telco Systems for
broadband and network access products. A material curtailment in the Bell
Atlantic order rate, if not offset by sales to other customers, would result in
insufficient gross margin to cover the current level of operating costs and
would adversely impact total company results. Other significant customers
include Walker and Associates and Sprint which each represented 12% of sales in
fiscal 1998. MCI Communications and Walker and Associates represented 11% and
10% of sales in fiscal 1997, respectively. In fiscal 1998 British Telecom, a
major European carrier, represented 8% of Telco Systems' revenues. In fiscal
1996, Sprint and Walker and Associates each represented 13% and 11%,
respectively. International revenue represented 12% of total revenue in fiscal
1998, 7% of total revenue in fiscal 1997 and 4% in fiscal 1996.
 
     Telco Systems markets its products through a combination of its own sales
force, value-added resellers and distributors. Installation is primarily
performed by third party providers. Telco Systems has technical support and
applications engineering personnel and offers training of customer personnel.
 
     Orders and Backlog.  In fiscal 1998, Telco Systems received orders totaling
$105.0 million. Of this amount, $59.7 million was for broadband transmission
products, $41.8 million was for network access products, and $3.5 million was
for bandwidth optimization products. During the first quarter of fiscal 1998,
Telco Systems was notified by a major customer, MCI Communications, of its
intention to cancel an order for
                                       116
<PAGE>   128
 
Access60 products in the amount of $6.9 million. Had this cancellation been
reflected in fiscal 1997, total orders in fiscal 1997 would have been $107.5
million. Firm backlog shippable within a twelve-month period was approximately
$12.2 million at the end of fiscal 1998, compared to approximately $21.2 million
at the end of fiscal 1997. Firm backlog would have been $14.3 million if the
previously discussed cancellation occurred in fiscal 1997. Broadband
transmission products comprised 43% of the backlog for fiscal year 1998 and 26%
for fiscal 1997. Network access products represented 56% of backlog at fiscal
1998 year end, 72% at fiscal 1997 year end. Telco Systems' order trend is
characterized by short customer-scheduled delivery cycles. Accordingly, a
substantial portion of sales in each fiscal quarter are derived from orders
received in the quarter. In Telco Systems' experience, its backlog at a given
time is not necessarily indicative of prospective sales volume. In addition to
the short delivery cycles, customers may revise scheduled delivery dates, revise
product configuration or cancel orders.
 
     Competition.  Telco Systems competes in its markets based upon
price/performance advantages offered by a number of its products, certain
product features, and its ability to meet customer delivery requirements on a
timely basis. Most of Telco Systems' competitors have greater financial,
technological and personnel resources than Telco Systems. Telco Systems'
competitors in the broadband transmission market are predominantly large,
full-line, integrated manufacturers of telecommunications equipment, such as
Lucent Technologies, Fujitsu, Northern Telecom Limited, Alcatel, NEC and ADC
Telecommunications. Many of these competitors have introduced newer SONET
transmission products which the telephone operating companies are deploying in
public networks. The availability of such SONET products by competitors provides
a distinct product advantage for them in certain customer applications. However,
the higher cost of the SONET products, typically 20-50% more expensive than the
asynchronous transmission products, is providing a continued strong demand for
Telco Systems' asynchronous transmission products in certain customer
applications. Telco Systems' principal competitors with respect to the network
access product market include Premisys Communications, Verilink Corp., Newbridge
Networks, Tellabs and Carrier Access Corp. Telco Systems' believes that it has
substantially strengthened its competitive position in this market with the
availability of new features for the Access60 product, introduction of the new
EdgeLink 100 and Access45 products and new products from the Jupiter Technology
and Synaptyx acquisitions, as well as with a stronger network of distributors.
Telco Systems also believes that the redundancy, high-density application and
the fail-safe nature of the Access60 architecture makes the product more
suitable for the service providers market. Primary competitors for bandwidth
optimization products are Fastcom and Symplex, which focus on data compression
technologies for lower data rates in the range of 64Kbps. Telco Systems believes
that its data compression technology has significant cost and performance
advantages for higher data rates in the range of 256Kbps and 1.544Mbps.
 
     Research and Development.  Telco Systems maintains four technology centers
for research and development located in Norwood, Massachusetts, Waltham,
Massachusetts, Germantown, Maryland and Fremont, California. In the broadband
transmission product area, Telco Systems is concentrating its research and
development efforts on new products for delivering more cost-effective solutions
for DS3-based systems in the local loop distribution portion of the telephone
network. In the network access product area, development programs continue for
further enhancements and newer features for digital loop access and data
services applications for Access45 and Access60 Network Access servers. In both
areas, a significant portion of the R&D investment is going towards development
of lower-cost designs to improve gross margins of existing products. Programs
for new products are based on market analysis and estimates of customer demand
which are subject to continuing change. Therefore, there can be no assurance
that sales of such products will meet current expectations.
 
     Spending on research and development activities of $15.5 million
represented 14% of sales in fiscal 1998. This compares with $15.4 million in
fiscal 1997 and $18.0 million in fiscal 1996 which represented 13% and 19% of
sales in each year, respectively. Telco Systems expects to maintain the fiscal
1998 level of spending for research and development into fiscal 1999.
 
     From time to time Telco Systems has employed consultants to perform
research and development functions. Telco Systems plans to continue this
practice as a means of augmenting its internal research and development
capabilities.
                                       117
<PAGE>   129
 
     Employees. As of August 30, 1998, Telco Systems had 301 employees, of whom
84 were in sales, sales support and marketing, 95 in product development, 75 in
manufacturing and 47 in administration. Competition for highly skilled
engineering, managerial, sales, marketing and product development personnel is
very intense. Telco Systems believes that its future success will depend in
large part on its ability to attract and retain such individuals. Accordingly,
the loss of key personnel could materially and adversely affect Telco Systems'
business, results of operations and financial condition. There can be no
assurance that Telco Systems will be successful in attracting and retaining the
personnel required to engineer, manage, market or develop its products and
conduct its operations successfully. Telco Systems considers its employee
relations to be excellent and is not a party to any collective bargaining
agreement.
 
     Manufacturing. Telco Systems uses major contract manufacturers to supply
final products, including US Assemblies, New England, Inc. and SCI Technologies,
Inc. Telco Systems' contract manufacturing process primarily involves the
assembly of electronic components onto custom-designed printed circuit boards,
incorporating these boards into larger system packages, and testing the finished
products to assure their proper functioning in accordance with product
specifications. Most components used in the process are standard electrical,
electronic and mechanical parts available from many suppliers.
 
     Some inspection, final test and system assembly functions are performed at
Telco Systems' Norwood, Massachusetts facility. In addition, Telco Systems
produces customer configured rack systems and performs repair and warranty
functions for customers.
 
     Telco Systems presently maintains a favorable relationship with its
contract manufacturers and its other suppliers and does not presently anticipate
any difficulties that would prevent timely procurement of scheduled product.
 
     Although Telco Systems has not experienced significant difficulty in
obtaining desired quantities from any of its single sources or other vendors,
business could be adversely affected if components used in its products were not
available on a timely basis.
 
     Regulatory and Legislative Matters. Regulations of the Federal
Communications Commission affect various products of Telco Systems. Certain
regulations require that products which reside on a customer's premises and
interconnect the public switched network meet certain standards to prevent harm
to the network. Other regulations limit the levels of electromagnetic radiation
which may emanate from an electronic device located on a customer's premise.
Telco Systems currently complies with these regulations and believes it will be
able to comply with these regulations in the future. Changes in existing laws
and regulations which govern the telecommunications industry could affect the
business of Telco Systems.
 
     Patents. Telco Systems currently holds several patents and has patent
applications pending. Management believes, however, that timely implementation
of technological advances, responsiveness to market requirements, depth of
technical expertise and a high level of customer service and support are more
important to its success than patent rights.
 
PROPERTIES
 
     Telco Systems' corporate offices and manufacturing operations are located
in Norwood, Massachusetts. Engineering, sales and marketing activities are
located in Norwood and Waltham, Massachusetts, Germantown, Maryland and Fremont,
California.
 
     Telco Systems leases a 216,000 square foot manufacturing, research and
administration facility in Norwood, Massachusetts, that is owned by a limited
partnership in which Telco Systems has a 50% partnership interest. Approximately
60% of this facility is utilized by Telco Systems. Excess costs associated with
idle portions of the facility have been included in the restructuring charge
recorded by Telco Systems in fiscal 1993. On November 11, 1994, Telco Systems
entered into an agreement for the lease of an 118,000 square foot manufacturing,
research and administration facility in Fremont, California. During fiscal 1996,
portions of this facility were identified as excess following the consolidation
of manufacturing operations into the Norwood, Massachusetts facility. The
consolidation plan was completed during fiscal 1997.
 
                                       118

     Telco Systems leases additional facilities, primarily for sales and sales
support in: Overland Park, Kansas; Dallas, Texas; The United Kingdom; Hong Kong;
and primarily for research and development in: Waltham, Massachusetts and
Germantown, Maryland under one to five-year leases, each facility being between
500 and 5,000 square feet. Telco Systems believes that its present facilities
are adequate for its current level of operations.
 
     Telco Systems owns substantially all of its equipment except for certain
equipment purchased by Telco Systems within the eighteen month period prior to
August 31, 1997. This equipment is leased to Telco Systems as discussed in Note
6 to Telco Systems consolidated financial statements included herein. See "Index
to Financial Statements."
 
LEGAL PROCEEDINGS
 
     From time to time, Telco Systems is involved in various legal proceedings
relating to claims arising in the ordinary course of its business. Neither Telco
Systems nor any of its subsidiaries is party to any legal proceeding, the
outcome of which, individually or in the aggregate, is expected to have a
material adverse effect on Telco Systems' financial condition or results of
operations.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS
 
     Fiscal 1998 Compared with Fiscal 1997.  Sales in fiscal 1998 decreased 3.9%
to $113.2 million compared with $117.8 million in fiscal 1997. Increased sales
of Telco Systems' new network access products and broadband products were not
sufficient to offset declining sales of older network access and asynchronous
products.
 
     In fiscal 1998, broadband transmission product sales represented 52% of
total sales reflecting a decrease of 9% compared with fiscal 1997. Demand for
asynchronous products declined during fiscal 1998 resulting in a 15% decrease in
sales of these products. This decrease was partially offset by sales of Telco
Systems' new Edgelink100 multiplexer. Approximately 80% of Telco Systems' sales
of these products are used by telephone company customers to provide high
bandwidth fiber optic services in the feeder or distribution section of the
public telephone network. Sales to one RBOC represented 70% and 60% of sales of
broadband transmission products in fiscal 1998 and fiscal 1997, respectively. As
a percent of total sales, this RBOC represented 36% and 33% in fiscal 1998 and
fiscal 1997, respectively. In fiscal 1998, access product sales represented 45%
of total sales reflecting an increase of 4% compared with fiscal 1997. Growth in
this product group can be attributed to sales of Telco Systems' new Access 60
server which increased 41% compared with fiscal 1997 and was partially offset by
sales of older low-end access products which declined 37% compared with last
year. The Access 60 product represented 63% of access product sales in fiscal
1998 compared with 46% in fiscal 1997. In fiscal 1998, sales of bandwidth
optimization products represented 3% of total sales compared with 5% in fiscal
1997.
 
     Total orders booked in fiscal 1998 amounted to $105.0 million, reflecting a
decrease compared with fiscal 1997 orders of $114.4 million. Backlog at the end
of fiscal 1998 decreased to $12.2 million compared with $21.2 million at the end
of the previous year. During the first quarter of fiscal 1998, Telco Systems was
notified by a major customer, MCI Communications, of its intention to cancel an
order for Access 60 products in the amount of $6.9 million. Had this
cancellation been reflected in fiscal 1997, total orders would have been $107.5
million. Firm backlog would have been $14.3 million if this order cancellation
had occurred in fiscal 1997.
 
     Telco Systems' major customers include telephone operating companies and
long distance carriers. Sales to RBOC and other major telephone companies
represented 41% of total sales compared with 43% in fiscal 1997. The major long
distance carriers represented 12% of sales in fiscal 1998 compared with 20% in
fiscal 1997. International revenue represented 12% of total revenue in fiscal
1998 compared with 7% in fiscal 1997.
 
     In fiscal 1998 Telco Systems recorded a net loss of $3.3 million or $.30
per share compared with a net loss in fiscal 1997 of $1.1 million or $.10 per
share. Expenses related to the pending Merger and the write off of $5.1 million
of purchased research and development resulted in a larger net loss in fiscal
1998 compared with fiscal 1997.
 
     Gross profit in fiscal 1998 was $42.0 million and represented 37% of sales.
In fiscal 1997, gross profit was $42.9 million or 36% of net sales. This
decrease in gross profit resulted from lower sales and was offset by an increase
in gross profit percentage as the product revenue mix shifted towards higher
margin products and Telco Systems' cost reduction efforts, primarily in the
access products group. Additionally, gross profit percent improved due in part
to the benefits gained from Telco Systems' manufacturing outsource strategy
announced in the second quarter of fiscal 1998.
 
     Research and development expense amounted to $15.5 million which was
substantially even with fiscal 1997. Spending continued on new product
development efforts in the access products area and the broadband products area.
Research and development expense represented 14% of sales in fiscal 1998
compared with 13% of sales in fiscal 1997.
 
     In January 1998, Telco Systems acquired substantially all the assets of
Jupiter Technology, Inc., a privately held developer of network access products,
for $6.2 million in cash and Telco Systems common stock. Of this amount, $5.1
million was allocated to purchase in-process research and development, which
consists of the value of Jupiter Technology products in the development stage
that were not considered to have reached technological feasibility as of the
acquisition date. The $5.1 million was immediately expensed in accordance with
applicable accounting rules.
 
                                       120
<PAGE>   132
 
     The Income Approach was utilized to value the acquired research and
development technologies in the Jupiter Technology acquisition. The Income
Approach values technologies by projecting the potential cash flows related to
those technologies and discounting the cash flows to their present values using
a discount rate reflective of the risk of achieving the cash flows. The
projected cash flows include estimates of the remaining costs to complete the
in-process technologies.
 
     Jupiter Technology development efforts as of the acquisition date were
concentrated on a next generation network access product that utilizes Frame
Relay and asynchronous transfer mode ("ATM") technologies. This new Jupiter
product is expected to broaden Telco Systems' integrated access product
offerings and improve its competitive position. According to various industry
analysts, the ATM access equipment market is expected to be approximately $1
billion by the year 2000. Public network carriers have been building out their
core ATM infrastructure over the past several years. What ATM technology offers
is an economical way to provide access to that infrastructure. Moreover, with
the increase of voice, video and data traffic over public networks, there is a
growing need for carriers to integrate multiple communication transport
mechanisms and gain bandwidth efficiencies.
 
     At the acquisition date, Telco Systems' management estimated that
technological feasibility would be determined on the new Jupiter product within
six months, at an estimated cost to complete of $1.8 million. Telco Systems'
management currently estimates that the product will be commercially viable
during the latter part of fiscal 1999. Estimated costs to complete this product
development are $1.5 million for fiscal 1999. The expected sources of funding
were scheduled research and development expenses from the operating budget of
Telco Systems provided by the operating assets and liabilities of Telco Systems.
 
     Sales, marketing and administration expense was $24.3 million in fiscal
1998 compared with $29.7 million in fiscal 1997. The fiscal 1997 period included
expenses related to the realignment of certain selling and marketing activities.
In general, the lower level of spending in fiscal year 1998 compared with fiscal
year 1997 is reflective of Telco Systems' overall goal of reduced sales, general
and administrative spending and productivity improvements.
 
     During the first quarter of fiscal 1997, Telco Systems liquidated its
equity position in an international distributor of Telco Systems' products due
to certain changes in strategic objectives. The sale of this investment,
originally made in fiscal 1995, yielded a one-time gain of $1.1 million.
 
     Amortization expense relates to the acquisition of the broadband family of
products in 1983, certain channel bank products in 1984, the acquisition of
Magnalink Communications Corporation in 1992, and the acquisition of Jupiter
Technology, Inc. in January 1998. In fiscal 1998, amortization expense was $.8
million compared with $.7 million in fiscal 1997.
 
     Interest income was $.7 million in both fiscal 1998 and fiscal 1997.
 
     In fiscal 1998, Telco Systems recorded $.3 million of income tax expense
relating to timing differences between Telco Systems' net operating loss and
taxable income.
 
     Fiscal 1997 Compared with Fiscal 1996.  Sales in fiscal 1997 increased 25%
to $117.8 million compared with $94.0 million in fiscal 1996. Increased
shipments of Access 60 network access products and broadband transmission
products more than offset decreased sales of older network access products.
 
     In fiscal 1997, broadband transmission product sales represented 54% of
total sales reflecting an increase of 35% compared with fiscal 1996. Telco
Systems continued to experience increased demand for asynchronous products
exceeding the 30% growth rate experienced in fiscal 1996. Approximately 80% of
Telco Systems' sales of these products are used by telephone company customers
to provide high bandwidth fiber optic services in the feeder or distribution
section of the public telephone network. Sales to one RBOC represented 60% and
61% of sales of broadband transmission products in fiscal 1997 and fiscal 1996,
respectively. As a percent of total sales, this RBOC represented 33% and 31% in
fiscal 1997 and fiscal 1996, respectively. In fiscal 1997, access product sales
represented 41% of total sales reflecting an increase of 18% compared with
fiscal 1996. Substantially all of this growth can be attributed to sales of
Telco Systems' new Access 60 server which increased 87% compared with fiscal
1996. The Access 60 product represented 46% of access product sales in fiscal
1997 compared with 29% in fiscal 1996. This increase was partially offset by a
decline in sales of older low-end access products. In fiscal 1997, sales of
bandwidth optimization products represented 5% of total sales and remained
substantially even with fiscal 1996.
 
                                       121
<PAGE>   133
 
     Total orders booked in fiscal 1997 amounted to $114.4 million, slightly
ahead of fiscal 1996 orders of $113.5 million. Backlog at the end of fiscal 1997
decreased to $21.2 million compared with $24.8 million at the end of the
previous year. During the first quarter of fiscal 1998, Telco Systems was
notified by a major customer, MCI Communications, of its intention to cancel an
order for Access 60 products in the amount of $6.9 million. Had this
cancellation been reflected in fiscal 1997, total orders would have been $107.5
million. Firm backlog would have been $14.3 million if this order cancellation
had occurred in fiscal 1997.
 
     Telco Systems' major customers include telephone operating companies and
long distance carriers. Sales to RBOC and other major telephone companies
represented 43% of total sales compared with 42% in fiscal 1996. The major long
distance carriers represented 20% of sales on fiscal 1997 compared with 19% in
fiscal 1996. International revenue represented 7% of total revenue in fiscal
1997 compared with 4% in fiscal 1996.
 
     In fiscal 1997 Telco Systems recorded a net loss of $1.1 million or $.10
per share compared with a net loss in fiscal 1996 of $15.5 million or $1.50 per
share. The fiscal 1996 net loss included a net restructuring charge of $4.2
million or $.41 per share which is discussed in note 7 to the financial
statements. Additionally, fiscal 1996 included non-recurring charges associated
with the transfer of manufacturing operations from Fremont, California to
Norwood, Massachusetts. Increased revenues and lower operating expenses were
primarily responsible for the improved operating results compared with fiscal
1996.
 
     Gross profit in fiscal 1997 was $42.9 million and represented 36% of sales.
In fiscal 1996, gross profit was $36.7 million or 39% of net sales. This
decrease in gross profit percentage resulted in part as the product revenue mix
shifted towards lower margin products, primarily in the access products group.
To reverse this trend, efforts are continuing into fiscal 1998 to reduce product
cost through manufacturing process improvements and product enhancements.
 
     Research and development expense amounted to $15.4 million and represented
a decrease of 15% compared with fiscal 1996. This decrease resulted as
development efforts for certain broadband products were curtailed. Remaining
resources were focused on new product efforts in the access products area.
Research and development expense represented 13% of sales in fiscal 1997
compared with 19% of sales in fiscal 1996.
 
     Sales, marketing and administration expense was $29.7 million in fiscal
1997 compared with $30.4 million in fiscal 1996. Lower spending in fiscal 1997
resulted from Telco Systems' consolidation actions which occurred in the third
quarter of fiscal 1996. This favorable spending variance was partially offset by
additional costs relating to certain selling activity realignments which
occurred in the third quarter of fiscal 1997.
 
     During the first quarter of fiscal 1997, Telco Systems liquidated its
equity position in an international distributor of Telco Systems' products due
to certain changes in strategic objectives. The sale of this investment,
originally made in fiscal 1995, yielded a one-time gain of $1.1 million.
 
     Amortization expense relates to the acquisition of the broadband family of
products in 1983, certain channel bank products in 1984 and the acquisition of
Magnalink Communications Corporation in 1992. In fiscal 1997, amortization
expense was $.7 million in fiscal 1997 compared with $.8 million in fiscal 1996.
 
     Interest income was $.7 million and $1.1 million in fiscal 1997 and fiscal
1996, respectively. This decrease resulted as operating requirements for cash
reduced the amounts available to generate interest income.
 
     In fiscal 1997, Telco Systems' operating loss did not generate currently
available tax benefits.
 
     Liquidity and Capital Resources.  During fiscal 1998, cash and marketable
securities increased by $8.3 million resulting in a year-end balance of $21.0
million compared with $12.7 million at the end of fiscal 1997. Cash of $14.2
million was provided by operating activities, which included decreased inventory
of $16.4 million. Cash was used by investing activities for the acquisition of
Jupiter Technology for $4.3 million. In addition, capital expenditures of $2.5
million were principally related to new product development tools and improved
product testing capability. Proceeds from the sale of Telco Systems common stock
under various stock option and purchase plans provided cash in the amount of
$2.0 million.
 
     Working capital at August 30, 1998 was $39.7 million, compared with $40.4
million at August 31, 1997. The ratio of current assets to current liabilities
at fiscal year end was 2.9 which remained unchanged from the end of fiscal 1997.
 
                                       122
<PAGE>   134
 
     Telco Systems maintains a $20.0 million secured line of credit with Fleet
Bank which is available to fund working capital requirements through December
31, 1998. Although Telco Systems did not utilize any of its financing
alternatives in fiscal 1998, approximately $0.4 million was reserved to cover
various guarantees in effect at August 30, 1998 relating to European Community
customs and duties.
 
     Management believes that its cash and marketable securities and the
availability of its various financing arrangements will be sufficient to fund
operating cash requirements and future growth for the foreseeable future.
 
     Telco Systems' practice has been to retain cash provided by operations to
fund future growth. Accordingly, Telco Systems has never declared or paid a cash
dividend on its capital stock.
 
     Year 2000 Issue.  The year 2000 will pose a unique set of challenges to
those industries reliant on information technology. As a result of methods
employed by early programmers, many software applications and operational
programs may be unable to distinguish the year 2000 from the year 1900. If not
effectively addressed, this problem could result in the production of inaccurate
data, or, in the worst cases, complete system failure.
 
     In April 1998, Telco Systems formally adopted a plan to address year 2000
compliance in its computer systems and applications. In accordance with the
plan, management estimates the total cumulative costs will be approximately
$1,100,000. During fiscal 1998, approximately $100,000 was expended towards year
2000 compliance.
 
     Telco Systems' products have been either tested and found to be year 2000
compliant, or deemed not subject to the testing requirement because they do not
contain a real-time clock. The third phase of the plan includes a process to
evaluate the readiness of its major suppliers. As of August 30, 1998, the plan
is on schedule and is expected to be completed in mid-1999.
 
     Management believes that the expenditures required to bring Telco Systems'
systems into compliance will not have a materially adverse effect on Telco
Systems' ability to operate beyond the year 1999. However, the year 2000 problem
is pervasive and complex and can potentially affect any computer process.
Accordingly, no assurance can be given that year 2000 compliance can be achieved
without additional unanticipated expenditures and uncertainties that might
affect future financial results.
 
     Factors That May Affect Future Financial Results.  Discussions in this
Joint Proxy Statement/ Prospectus include statements concerning Telco Systems'
future products, expenses, revenue, liquidity and cash needs as well as Telco
Systems' future operations and financial results. These forward-looking
statements are based on current expectations. Accordingly, Telco Systems assumes
no obligation to update this information. Numerous factors, including but not
limited to the factors described under "Risk Factors" above as well as the
pending Merger, economic and competitive conditions, incoming order levels,
shipment volumes, and product margins, could cause actual results to differ from
those described in these statements. Prospective investors and stockholders
should carefully consider the foregoing factors, as well as those set forth
below in evaluating these forward-looking statements.
 
     Telco Systems' backlog may not be representative of actual sales for any
succeeding period because of the timing of orders, delivery intervals, customer
and product mix, the possibility of changes in delivery schedules, and additions
or cancellation of orders. Historically, a significant portion of Telco Systems'
sales in any quarter result from orders received in the same period; thus, order
delays could have an immediate and materially adverse impact on sales and
profit. Recent merger activity among some of Telco Systems' large customers
could adversely affect future orders as those customers reassess their strategic
direction. NYNEX, Telco Systems' largest customer merged with Bell Atlantic in
fiscal 1997. Although Telco Systems believes that its products continue to offer
a competitive advantage to Bell Atlantic, there can be no assurance that their
historic order level will continue. If Bell Atlantic and GTE complete their
contemplated merger, the combined entity will become a large customer of Telco
Systems.
 
     Telco Systems operates in a highly competitive environment and in a highly
competitive industry, which include significant pricing pressures. These
competitive pressures could cause reduced demand for Telco Systems' products. If
Telco Systems was not successful in winning future business opportunities, there
could be insufficient revenue to cover costs and expenses incurred in
anticipation of these opportunities. Accordingly,
                                       123
<PAGE>   135
 
Telco Systems may from time to time experience unanticipated intense competitive
pressure, possibly causing operating results to vary from those expected.
 
     Telco Systems' future operating results are dependent on its ability to
develop, produce and market new and innovative products and services. As part of
this effort, Telco Systems has invested in new technology with the acquisition
of Jupiter Technology and the acquisition of Synaptyx. There can be no assurance
that either of these investments will result in successful products. Critical to
Telco Systems' growth strategy is the acceptance of the Access 60 product and
the EdgeLink family of products. There are numerous risks inherent in the
complex process of product development, including rapid technological change and
the requirement that Telco Systems bring to market in a timely fashion new
products and services which meet customers' changing needs. The introduction of
newer technologies could result in lower demand for Telco Systems' products and
cause inventory on hand to become obsolete. Telco Systems experiences intense
competition for skilled employees who are in great demand. If important
technical and management positions remain unfilled, completion of product
development and other programs could be delayed causing financial results to be
adversely affected.
 
     Historically, Telco Systems has generated a disproportionate amount of its
operating revenues toward the end of each quarter, making precise prediction of
revenues and earnings particularly difficult and resulting in risk of variance
of actual results from those forecast at any time. In addition, Telco Systems'
operating results historically have varied from fiscal period to fiscal period.
Accordingly, Telco Systems' financial results in any particular fiscal period
are not necessarily indicative of results for future periods.
 
     Supplementary Data.  The following table presents unaudited quarterly
operating results for each of Telco Systems' last eight quarters. This
information has been prepared by Telco Systems on a basis consistent with Telco
Systems' audited consolidated financial statements and includes all adjustments,
consisting only of normal recurring accruals, that Telco Systems considers
necessary for a fair presentation in accordance with GAAP. Such quarterly
results are not necessarily indicative of future operating results. This
information should be read in conjunction with Telco Systems' consolidated
financial statements and notes thereto included elsewhere herein. See "Index to
Financial Statements."

     Quantitative and Qualitative Disclosures About Market Risk.  Telco Systems
is exposed to market risk related to changes in interest rates on its borrowing
under its $20,000,000 credit facility with Fleet National Bank (the "Credit
Facility"); however, Telco Systems does not believe these risks to be material
because it currently has made no borrowing under the Credit Facility. Under the
Credit Facility, revolving line of credit bears interest at the prime interest
rate.
 
     Telco Systems has no derivative financial instruments or derivative
commodity instruments or investments. Telco Systems invests its cash and cash
equivalents in high-quality and highly liquid investments consisting of
certificates of deposit, money market instruments and overnight investments in
high grade commercial paper. As of November 6, 1998, Telco Systems' cash and
cash equivalents and investments consisted primarily of taxable money market
instruments, bank certificates of deposit, commercial paper and overnight
repurchase agreements with maturities of less than 60 days. Telco Systems
believes that its overall market risk exposure with respect to the investment of
its cash and cash equivalents is not material because
 
                                       124
<PAGE>   136
 
the overall contribution of interest income relative to net revenue of Telco
Systems was less than one percent for fiscal 1998 and Telco Systems does not
anticipate a higher contribution percentage during fiscal 1999.
 
     Less than one percent of Telco Systems' transactions are conducted in
currencies other than United States Dollars and as such Telco Systems does not
currently have material exposure to foreign currency risk.

               UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS
 
     The following Unaudited Pro Forma Combined Financial Statements of World
Access give effect to the consummation of the Merger and to the several
transactions that World Access has completed or are currently contemplated. The
Unaudited Pro Forma Combined Statements of Operations give effect to: (1) the
ATI acquisition; (2) the acquisition of a majority interest in NACT (the "NACT
Stock Purchase"); (3) the acquisition of the remainder of NACT (the "NACT
Transaction"); (4) the Resurgens Transaction; and (5) the Merger as if each of
these acquisitions had occurred on January 1, 1997. The Unaudited Pro Forma
Combined Balance Sheet gives effect to: the NACT Transaction, the Resurgens
Transaction and the Merger as if they had been completed on June 30, 1998.
 
     As Telco Systems' fiscal year end, August 30, differs from World Access'
fiscal year-end by more than 93 days, Telco Systems' results of operations for
the period from November 25, 1996 through November 30, 1997 were used in
preparing the Unaudited Pro Forma Combined Statement of Operations for the year
ended December 31, 1997. Telco Systems' results of operations for the six months
from March 2, 1998 through August 30, 1998 were used in preparing the Unaudited
Pro Forma Combined Statement of Operations for the six months ended June 30,
1998. As such, Telco Systems' results of operations for the period from December
1, 1997 through March 1, 1998 are not included in the Unaudited Pro Forma
Combined Statements of Operations presented herein. Telco Systems' revenue, cost
of sales, operating loss and net loss for such period were $26.0 million; $15.5
million; $4.6 million and $4.6 million, respectively. Telco Systems' unaudited
June 30, 1998 balance sheet was utilized in preparing the Unaudited Pro Forma
Combined Balance Sheet as of June 30, 1998.
 
     The pro forma adjustments are based upon currently available information
and upon certain assumptions that the management of World Access believes are
reasonable. Each of the acquisition transactions above has been accounted for
using the purchase method of accounting. The adjustments recorded in the
Unaudited Pro Forma Combined Financial Statements represent the preliminary
determination of these adjustments based upon available information. There can
be no assurance that the actual adjustments will not differ significantly from
the pro forma adjustments reflected in the Unaudited Pro Forma Combined
Financial Statements.
 
     In connection with the consummation of the pending Merger, World Access
expects to record charges representing the estimated portion of the purchase
price allocated to in-process research and development of $60.7 million. In
addition, in the six month period ended June 30, 1998, World Access recorded
charges representing the estimated portion of the purchase price allocated to
in-process research and development of $44.6 million and $5.4 million for the
NACT Stock Purchase and ATI acquisition, respectively, and World Access has
assumed, for purposes of these pro forma combined financial statements, that it
will record $21.9 million in additional charges representing the estimated
purchase price allocated to in-process research and development in connection
with the NACT Transaction. Since these charges are directly related to the
acquisitions and will not recur, the Unaudited Pro Forma Combined Statements of
Operations have been prepared excluding these one-time non-recurring charges.
 
     The Unaudited Pro Forma Combined Financial Statements are not necessarily
indicative of the financial position or the future results of operations or
results that might have been achieved if the foregoing acquisition transactions
had been consummated as of the indicated dates. The Unaudited Pro Forma Combined
Financial Statements should be read in conjunction with the historical
consolidated financial statements of Old World Access, ATI, NACT and Telco
Systems, the historical combined financial statements of Resurgens and the
related notes thereto contained elsewhere herein. See "Index to Financial
Statements."

GENERAL HISTORICAL INFORMATION:
 
ACQUISITIONS OF ATI AND NACT
 
     The ATI acquisition consummated on January 29, 1998 and the NACT Stock
Purchase consummated on February 27, 1998 have been accounted for under the
purchase method of accounting. The historical consolidated financial statements
of World Access include the results of the operations of ATI and NACT from
February 1, 1998 and March 1, 1998, respectively. The purchase price of ATI and
the majority interest in NACT was allocated to the fair values of the net assets
acquired, to in-process research and development projects and to goodwill.
During the first quarter of 1998, $5.4 million and $44.6 million of purchased
in-process research and development technologies related to the ATI acquisition
and the NACT Stock Purchase, respectively, was expensed in accordance with the
applicable accounting rules. See Note 2 to Consolidated Financial Statements in
the World Access June 30 Form 10-Q for further descriptions of these
acquisitions.
 
AEROTEL LITIGATION
 
     On August 24, 1996, Aerotel, Ltd. and Aerotel U.S.A., Inc. (collectively,
"Aerotel") commenced an action against NACT and a customer of NACT alleging that
telephone systems manufactured and sold by NACT incorporating prepaid debit card
features infringe upon Aerotel's patent which was issued in November 1987. See
Note 8 to Consolidated Financial Statements in the World Access June 30 Form
10-Q for further description of this litigation.
 
     As part of the negotiations relating to the acquisition of NACT, Old World
Access and GST Telecommunications, Inc. agreed to share evenly any Aerotel
judgment against NACT, including NACT's legal fees. Subsequent to the NACT Stock
Purchase, World Access has been actively engaged in settlement negotiations. On
October 26, 1998, Old World Access, GST and Aerotel agreed to settle the Aerotel
litigation. Including legal fees, the World Access portion of the Aerotel
settlement was approximately $3.3 million. These settlement costs have been
accounted for as additional NACT purchase price as of June 30, 1998.
 
IN-PROCESS RESEARCH AND DEVELOPMENT
 
     Overview.  The nature of the efforts required to develop the purchased
in-process technology into commercially viable products principally relate to
the completion of all planning, designing, prototyping, verification, and test
activities that are necessary to establish that the product can be produced to
meet its design specifications, including functions, features, and technical
performance requirements.
 
     The value of the purchased in-process technology was determined by
estimating the projected net cash flows related to such products, including
costs to complete the development of the technology and the future revenues to
be earned upon commercialization of the products. These cash flows were
discounted back to their net present value. The resulting projected net cash
flows from such projects were based on management's estimates of revenues and
operating profits related to such projects. These estimates were based on
several assumptions, including those summarized below for each respective
acquisition.
 
     If these projects to develop commercial products based on the acquired
in-process technology are not successfully completed the sales and profitability
of World Access may be adversely affected in future periods. Additionally, the
value of other intangible assets may become impaired.
 
     NACT.  NACT provides advanced telecommunications switching platforms with
integrated applications software and network telemanagement capabilities. NACT
designs, develops, and manufacturers all hardware and software elements
necessary for a fully integrated, turnkey telecommunications switching solution.
The nature of the in-process research and development was such that
technological feasibility had not been attained. Failure to attain technological
feasibility, especially given the high degree of customization required for
complete integration into the NACT solution, would have rendered partially
designed hardware and software useless for other applications. Incomplete design
of hardware and software coding would create a non-connective, inoperable
product that would have no alternative use.

   NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
     NACT's business plan called for a shift in market focus to larger
customers, both domestic and international; therefore, NACT had numerous
projects in development at the time of the acquisition. Additionally, the
pending completion of a major release of NACT's billing system required
significant development efforts to ensure continued integration with NACT's
product suite. The purchased in-process technology acquired in the NACT
acquisition was comprised of nine projects related to switching systems. These
projects were scheduled to be released between February 1998 and December 1999.
Most major projects had several ongoing sub-projects (e.g., a hardware design
project and a software design project). These projects include planned additions
of new products, based on undeveloped technologies, to NACT's suite of STX and
NTS products. The projects also include the creation of products for new product
suites. The research and development projects were at various stages of
development. None of the in-process projects considered in the write-off had
attained technological feasibility. The in-process projects do not build on
existing core technology; such existing technologies were valued as a separate
asset.
 
     NACT had thirteen projects (the nine switching projects noted above and the
related sub projects) in development at the time of acquisition. These projects
were at multiple stages along NACT's development timeline. Some projects were
beginning testing in NACT labs; others were at earlier stages of planning and
designing. Eleven projects were scheduled for release between February and
December of 1998. The remaining two projects were scheduled for staggered
release over 1998 and 1999. Revenue projections for the in-process technologies
reflected the anticipated release dates of each project.
 
     Revenue attributable to in-process technology was assumed to increase in
the first five years of the twelve-year projection at annual rates ranging from
52.7% to 7.2%, decreasing over the remaining years at annual rates ranging from
- -2.7% to -61.2% as other products are released in the marketplace. Projected
annual revenue attributable to in-process technology ranged from approximately a
low of $6.3 million to a high of $117.2 million within the term of the
projections. These projections were based on assumed penetration of the existing
customer base, synergies as a result of the NACT acquisition, and movement into
new markets. Projected revenues from in-process technology were assumed to peak
in 2002 and decline from 2003 through 2009 as other new products are expected to
enter the market.
 
     In-process technology's contribution to the operating profit of NACT
(earnings before interest, taxes and depreciation and amortization) was
projected to grow within the projection period at annual rates ranging from a
high of 119.2% to a low of 11.0% during the first five years, decreasing during
the remaining years of the projection period similar to the revenue growth
projections described above. Projected in-process technology's annual
contribution to operating profit ranged from approximately $1.7 million to $34
million within the term of the projections.
 
     The discount rate used to value the existing technology of NACT was 14.0%.
This discount rate was estimated relative to the overall business discount rate
of 15.0% based on (1) the completed status of the products utilizing existing
technology (i.e., the lack of development risk), and (2) the potential for
obsolescence of current products in the marketplace.
 
     The discount rate used to value the in-process technology of NACT was
15.0%. This discount rate was estimated relative to the overall business
discount rate of 15.0% based on (1) the incomplete status of the products
expected to utilize the in-process technology (i.e., development risk), (2) the
expected market risk of the planned products relative to the existing products,
(3) the emphasis on targeting larger customers for the planned products, (4) the
expected demand for the products from current and prospective NACT customers,
(5) the anticipated increase in NACT's sales force, and (6) the nature of
remaining development tasks relative to previous development efforts.
 
     Management estimates that the costs to develop the in-process technology
acquired in the NACT acquisition will be approximately $4.1 million in the
aggregate through the year 1999 ($3,249,000 in 1998 and $829,000 in 1999). The
expected sources of funding were scheduled research and development expenses
from the operating budget of NACT provided by the operating assets and
liabilities of NACT.

     ATI.  ATI develops and manufactures a series of high-performance digital
microwave/millimeter radio equipment. Their products reach across all frequency
bands and data rates and offer numerous features. The nature of the in-process
research and development was such that technological feasibility had not been
attained. Failure to attain technological feasibility would have rendered
partially designed equipment useless for other applications. ATI's products are
designed for specific frequency bandwidths and, as such, are highly customized
to those bandwidths and the needs of customers wishing to operate in them.
Products only partially completed for certain bandwidths cannot be used in other
bandwidths.
 
     Between each product line, various stages of development had been reached.
Additionally, within each product line, different units had reached various
stages of development. Of the products management considered in-process, none
had attained technological feasibility. The purchased-in-process technology
acquired in the ATI acquisition was comprised of three primary projects related
to high-performance, digital microwave/millimeter radio equipment. Each project
consists of multiple products. These projects were at multiple stages along
ATI's typical development timeline. Some projects were beginning testing in ATI
labs; others were at earlier stages of planning and designing. The majority of
the products were scheduled to be released during 1998 and 1999. Revenue
projections for the in-process technologies reflected the anticipated release
dates of each project.
 
     Revenue attributable to in-process technology was estimated to increase
within the first three years of the seven-year projection at annual rates
ranging from a high of 240.7% to a low of 2.3%, decreasing within the remaining
years at annual rates ranging from -30.9% to -60.9% as other products are
released in the marketplace. Projected annual revenue attributable to in-process
technology ranged from approximately a low of $10.1 million to a high of $71.1
million within the term of the projections. These projections were based on
assumed penetration of the existing customer base, synergies as a result of the
ATI acquisition, and movement into new markets. Projected revenues from
in-process technology were assumed to peak in 2001 and decline from 2003 through
2004 as other new products are expected to enter the market.
 
     In-process technology's contribution to the operating profit of ATI
(earnings before interest, taxes and depreciation and amortization) was
estimated to grow within the projection period at annual rates ranging from a
high of 665.9% to a low of 43.9% during the first four years, decreasing during
the remaining years of the projection period similar to the revenue growth
projections described above. Projected in-process technology's annual
contribution to operating profit ranged from approximately a low of -$900,000 to
a high of $9.1 million within the term of the projections.
 
     The discount rate used to value the existing technology of ATI was 23.0%.
This discount rate was estimated relative to the overall business discount rate
of 25.0% based on (1) the completed status of the products utilizing existing
technology (i.e., the lack of development risk), and (2) the potential for
obsolescence of current products in the marketplace.
 
     The discount rate used to value the in-process technology of ATI was 26.0%.
This discount rate was estimated relative to the overall business discount rate
of 25.0% based on (1) the incomplete status of the products expected to utilize
the in-process technology (i.e., development risk), (2) the expected market risk
of the planned products relative to the existing products, (3) the emphasis on
different markets than those currently pursued by ATI, and (4) the nature of
remaining development tasks relative to previous development efforts.
 
     Management estimates that the costs to develop the in-process technology
acquired in the ATI acquisition will be approximately $24.3 million in the
aggregate through the year 2002 ($3.3 million, $7.2 million, $7.6 million, $5.1
million, and $1.1 million in 1998, 1999, 2000, 2001, and 2002, respectively).
The expected sources of funding were scheduled R&D expenses from the operating
budget of ATI provided by the operating assets and liabilities of ATI.
 
     Telco Systems.  Telco Systems develops and manufactures products focused on
providing integrated access for network services. Telco Systems' products can be
separated into three categories: (1) broadband
 
                                       142

   NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
transmission products, (2) network access products, and (3) bandwidth
optimization products. Telco Systems' products are deployed at the edge of the
service provider's networks to provide organizations with a flexible,
cost-effective means of transmitting voice, data, video and image traffic over
public or private networks.
 
     At the time of acquisition, Telco Systems had eight primary projects in
development relating to next-generation telecommunication and data network
hardware. These projects were at various stages in the development process. Some
were about to enter the testing phase of the initial hardware prototype, while
others were still in the early concept and design specification stages. These
eight projects were scheduled for commercial release at various points in time
from December 1998 through late 1999/early 2000.
 
     Telco Systems' in-process research and development projects are being
developed to run on new communications protocols and technologies not employed
in its current products. These include HDSL, SONET, Voice over IP and ATM
inverse multiplexing. Additionally, the products to be commercialized from Telco
Systems' in process research and development are expected to include interface
support not in Telco Systems' current product line, including E1, DS3 and OC3.
 
     None of the in-process projects at Telco Systems considered in the
write-off are expected to achieve technological feasibility before the
consummation of World Access' acquisition of Telco Systems. Furthermore, if the
projects are not completed as planned, the in-process research and development
will have no alternative use. Failure of the in process technologies to achieve
technological feasibility may adversely affect the future profitability of World
Access.
 
     Revenue attributable to Telco Systems' aggregate in-process technology was
assumed to increase over the first six years of the projection period at annual
rates ranging from a high of 195% to a low of zero growth, reflecting both the
displacement of Telco Systems' old products by these new products as well as the
expected growth in the overall market in which Telco Systems' products compete.
Thereafter, revenues are projected to decline over the remaining projection
period at annual rates ranging from -14% to -42%, as the acquired in process
technologies become obsolete and are replaced by newer technologies.
 
     Management's projected annual revenues attributable to the aggregate
acquired in-process technologies, which assume that all such technologies
achieve technological feasibility, ranged from a low of approximately $28
million to a high of approximately $276 million. Projected revenues were
projected to peak in 2004 and decline thereafter through 2009 as other new
products enter the market.
 
     The acquired in-process technology's contribution to the operating income
of Telco Systems (and subsequently World Access) was projected to grow over the
first five years of the projection period at annual rates ranging from a high of
142% to a low of 20% with one intermediate year of marginally declining
operating income. Thereafter, the contribution to operating income was projected
to decline through the projection period. The acquired in-process technology's
contribution to operating income ranged from a loss of approximately $5 million
to a high of approximately $86 million.
 
     The discount rate used to value the existing technology was 20.0%. This
discount rate was selected because of the asset's intangible characteristics,
the risk associated with the economic life expectations of the technology, and
the risk associated with the financial assumptions with respect to the
projections used in the analysis.
 
     The discount rate used to value the in-process technologies was 25.0%. This
discount rate was selected due to several incremental inherent risks. First the
actual useful economic life of such technologies may differ from the estimates
used in the analysis. Second, risks associated with the financial projections on
the specific products that comprise the acquired in-process research and
development. The third factor is the incomplete and unproven nature of the
technologies. Finally, future technological advances that are currently unknown
may negatively impact the economic and functional viability of the in-process
R&D.
 
     Management expects that the cost to complete the development of the
acquired in-process technologies and to commercialize the resulting products
will aggregate approximately $16 million through 2001. Over the
 
                                       143

projection period, management expects to spend an additional aggregate $46
million on sustaining development efforts relating to the acquired in-process
technologies. These sustaining efforts include bug fixing, form-factor changes,
and identified upgrades.
 
UNAUDITED PRO FORMA COMBINED BALANCE SHEET:
 
NACT MINORITY INTEREST ADJUSTMENTS
 
     (A) The acquisition of the minority interest of NACT will be accounted for
under the purchase method of accounting. In addition, in accordance with
generally accepted accounting principles, the portion of the purchase price
allocable to the in-process research and development projects of NACT will be
expensed at the consummation of the NACT Transaction. The amount of the one-time
non-recurring charge is expected to approximate $21.9 million. Since this charge
is directly related to the acquisition and will not recur, the Unaudited Pro
Forma Statements of Operations have been prepared excluding this charge. World
Access has not determined the final allocation of the purchase price, and
accordingly, the amount ultimately determined may differ significantly from the
amounts shown below.
 
     The unallocated excess of purchase price over the fair value of the net
assets acquired is determined as follows (in thousands):

     (i) Represents an estimate of $1.0 million to be paid to the creditors of
Resurgens under a cash settlement plan proposed by World Access and
approximately $2.0 million to be paid to governmental creditors.
 
     (ii) The value assigned to the 3,750,000 restricted World Access shares to
be issued to the creditors and Renaissance Partners at the closing date will be
$25.17, the seven trading days average closing price of Old World Access common
stock, including the three days prior and the three days subsequent to May 12,
1998, the date economic terms of the Resurgens Transaction were announced, less
a 30% discount attributable to the restrictive nature of the shares. World
Access consulted with an independent financial advisor knowledgeable of the
transaction in determining the appropriate discount. Specific factors supporting
the discount are (1) the length of the restriction, (2) the number of shares
subject to restriction, and (3) the volatility of World Access common stock (the
closing price on the announcement date was $37.06 and the closing price on
November 3, 1998 was $22.56, a 39.1% reduction). Management of World Access
believes the discount rate to be used in valuing these restricted shares is
appropriate and reasonable.
 
     In addition to the shares noted above, the creditors and Renaissance
Partners will also be issued 7,500,000 restricted World Access shares at the
closing (the "Escrowed Shares"). These shares will be immediately placed into
escrow and will be valued at par value only, or $75,000. As it becomes probable
that the conditions for release from escrow will be met, the fair market value
of the shares as measured at that time will be recorded as additional goodwill
and stockholders' equity, respectively.

     Notwithstanding the foregoing, if the Exchange Closing Date is on or after
September 30, 1998, then the First Performance Period shall commence on the
first day of the calendar month in which the Exchange Closing occurs and shall
terminate on (and including) the last day of the sixth calendar month following
the month in which the Exchange Closing occurs, the release date shall be
forty-five (45) days after the end of such period and the Target EBITDA shall be
equal to the sum of (i) $2,100,000 for each calendar month of 1998 included in
the First Performance Period and (ii) $2,400,000 for each calendar month of 1999
included in the First Performance Period.
 
     If, after the Exchange, the EBITDA of Resurgens is less than the Target
EBITDA required for the release of Escrowed Shares in either of the First or
Second Performance Periods (and with respect to the Second Performance Period is
no less than zero), then, notwithstanding anything described herein, the
Escrowed Shares shall be released if the actual cumulative EBITDA for Resurgens
for such Performance Period and any subsequent Performance Periods equals or
exceeds the cumulative Target EBITDA for such Performance Periods.
 
     Notwithstanding anything to the contrary, (a) if during any calendar
quarter of the Second Performance Period, the closing price per share of the
World Access Common Stock as reported by Nasdaq equals or exceeds $65.00 for any
five consecutive trading days during such calendar quarter, then 25% of all of
the shares of Escrowed Shares shall be released on February 15, 2000, provided
that if no Escrowed Shares are eligible for release during any such calendar
quarter, then such Escrowed Shares shall become eligible for release in a
subsequent calendar quarter of the Second Performance Period if the closing
price per share of the World Access Common Stock as reported by Nasdaq equals or
exceeds $65.00 for a total number of consecutive trading days during such
subsequent calendar quarter equal to or exceeding the total number of trading
days which such closing price was required to equal or exceed for (i) such
subsequent calendar quarter and (ii) each of the previous calendar quarters
beginning with the calendar quarter for which such Escrowed Shares were not
eligible for release; (b) if the EBITDA of Resurgens for the Second Performance
Period equals or exceeds $52,775,000, then the Escrowed Shares related to the
Third Performance Period shall be released on February 15, 2000; and (c) all of
the Escrowed Shares shall be released upon a Change of Control (as defined in
the Exchange Agreement).
 
     (iii) The combined historical accounts of Resurgens include pre-petition
creditor liabilities of $334.5 million, which are classified as "liabilities
subject to compromise," and borrowings under the WorldCom, Inc.
debtor-in-possession financing facility of $22.0 million as of June 30, 1998,
respectively. These liabilities will be satisfied in connection with the Plan of
Reorganization, which has been approved by the creditors committee and was
confirmed by the bankruptcy court on September 3, 1998. Upon the closing of the
Resurgens Transaction, the creditors will receive shares of RCG common stock in
exchange for the surrender

                               WORLD ACCESS, INC.
 
   NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
of all of their claims against RCG. Immediately thereafter, the creditors'
shares of RCG will be cancelled and automatically converted into the right to
receive shares of World Access Common Stock, a portion of which will be received
directly and a portion of which will be deposited into escrow pending the
satisfaction of certain conditions. All such shares of World Access Common Stock
are subject to certain contractual restrictions.
 
     The confirmation of the Plan of Reorganization is a condition precedent to
the closing of the Resurgens Transaction. Therefore, the combined historical
stockholders deficit of $354.4 million as of June 30, 1998 has been adjusted to
reflect a $352.6 million reduction for the liabilities subject to compromise and
the WorldCom, Inc. debtor-in-possession financing facility for purposes of the
unaudited pro forma combined balance sheet.
 
     (iv) Estimates of fair market value of the licenses and the switching
equipment acquired have been made by management. These estimates are subject to
adjustment pending final valuations to be obtained from independent appraisers.
 
     (v) At the time the Resurgens Transaction is consummated, Resurgens is
expected to have in excess of $125 million in net operating loss carryforwards
available to offset future federal taxable income. Based on its current
assessment of the forecasted operating results of Resurgens and other pertinent
factors, management expects at least 35% of these future tax benefits will be
realized. Accordingly, a deferred tax asset of $44 million, net of a 65%
valuation allowance of approximately $29 million, has been reflected in the Pro
Forma Combined Balance Sheet. The amount of the valuation allowance is subject
to future analysis and may be revised prior to the closing of the Resurgens
Transaction.
 
     The pro forma loss of the combined entity is not indicative of the results
of operations that are expected to be achieved by the combined entity in the
future. The nature of Resurgens current operations are concentrated solely on
the international carriers' carrier business and an upgraded, efficient
operating network is now in place. Resurgens has a new, experienced management
team in place and has entered into several new contracts to increase its revenue
base, including a significant service contract with WorldCom Network Services,
Inc., a wholly owned subsidiary of WorldCom, Inc. Prior to the acquisition of
Resurgens, it is expected that Resurgens will be essentially debt free due to
its Chapter 11 bankruptcy proceedings. In addition, there are several closing
conditions that must be satisfied before the Resurgens Transaction is
consummated, including the achievement by Resurgens of monthly revenues of $25
million and related gross profit margin of greater than 5% for the calendar
month immediately preceding the closing date.
 
     (D) Eliminate existing stockholders' equity.
 
TELCO SYSTEMS PRO FORMA ADJUSTMENTS
 
     (E) The Merger will be accounted for under the purchase method of
accounting. In addition, in accordance with generally accepted accounting
principles, the portion of the purchase price allocable to the in-process
research and development projects of Telco Systems will be expensed at the
consummation of the acquisition. The amount of the one-time non-recurring charge
is expected to approximate $60.7 million. Since this charge is directly related
to the acquisition and will not recur, the Unaudited Pro Forma Statements of
Operations have been prepared excluding this charge. World Access has not
determined the final allocation of the purchase price, and accordingly, the
amount ultimately determined may differ significantly from the amounts shown
below.

     The amounts allocated to tangible and intangible assets acquired less
liabilities assumed exceed the purchase price by approximately $24.0 million.
This excess value over cost has been allocated to reduce proportionably the
values assigned to long-term assets in determining their fair values. As a
result in the change in fair values of the long-term assets, the deferred tax
liability associated with these assets was also adjusted.
 
     The table below is a summary of the preliminary amounts allocated to the
long-term assets, the allocation of the excess value over purchase price and the
resulting fair values of the assets acquired:

     (i) The total purchase price of Telco Systems was determined by multiplying
the number of shares of Telco Systems Common Stock outstanding (approximately
11.1 million shares) by the Minimum Nominal Value ($12). The total purchase
price was computed based on the Minimum Nominal Value because the value of the
Merger Consideration to which the holder of one share of Telco Systems Common
Stock would

   NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
otherwise be entitled (determined by multiplying the Exchange Ratio of .5862
(assuming that World Access does not elect to pay any portion of the Merger
Consideration in cash) by the average of the last reported sale prices of one
share of World Access Common Stock for the seven trading days surrounding the
October 13, 1998 announcement of the new economic terms of the Merger (or
$14.25)) would be less than the Minimum Nominal Value.
 
     Pursuant to the Merger Agreement, World Access, at its option, may pay a
portion of the Merger Consideration (which would otherwise be paid solely in
shares of World Access Common Stock) in cash, subject to the requirement that a
minimum of 45% of the Merger Consideration be paid in the form of World Access
Common Stock. For purposes of these pro forma combined financial statements,
World Access has assumed that the Merger Consideration will consist solely of
approximately 6.5 million shares of World Access Common Stock having an
approximate value of $133.4 million. The value of the World Access Common Stock
comprising Merger Consideration was determined by multiplying (i) the number of
shares of World Access Common Stock assumed to be issued (based an exchange
ratio of .5862) by (ii) $20.47, which represents the World Access Market Price
below which World Access would be obligated to issue additional shares of World
Access Common Stock or pay additional cash amounts to the Telco Systems
stockholders to ensure that they receive Merger Consideration having the Minimum
Nominal Value.
 
     If World Access elects to pay the minimum of 45% of the Merger
Consideration in the form of World Access Common Stock, then the Merger
Consideration would consist of approximately 2.9 million shares of World Access
Common Stock (having an approximate value of $60.0 million) and approximately
$73.4 million in cash. For purposes of each of the foregoing calculations, the
World Access Market Price was assumed to be $20.47.
 
     The total purchase price of Telco Systems for purposes of these unaudited
pro forma combined financial statements does not give effect to Telco Systems'
acquisition of Synaptyx in October 1998 pursuant to which Telco systems issued
approximately 576,000 shares of Telco Systems Common Stock, placed in escrow an
additional approximately 204,000 shares of Telco Systems Common Stock, the
release of which is subject to achieving certain operating performance criteria,
and issued options to acquire approximately 368,000 shares of Common Stock. As a
consequence of this transaction, World Access will be required in the Merger (i)
to issue an additional approximately 457,000 shares of World Access Common Stock
and options to acquire approximately 216,000 shares of World Access Common Stock
(assuming that the Merger Consideration is comprised solely of shares of World
Access Common Stock) or (ii) to issue an additional approximately 206,000 shares
of World Access Common Stock and options to acquire approximately 216,000 shares
of World Access Common Stock and pay approximately $5.1 million in cash
(assuming that 55% of the Merger Consideration is comprised of cash). The
acquisition of Synaptyx does not meet any of the materiality thresholds that
would require it to be given pro forma effect in this Joint Proxy
Statement/Prospectus.
 
     (ii) The net deferred tax asset of $13.1 million is comprised primarily of
gross temporary differences arising from the differences between book and tax
basis of certain assets and liabilities and for tax credits available to Telco
Systems and World Access. It is the opinion of management that these tax assets
are likely to be utilized by Telco Systems or World Access.
 
     (iii) The value of the acquired technology of $46.3 million is based on a
preliminary valuation report prepared by an independent appraiser as adjusted
for the pro rata allocation of the excess value over cost. The value of Telco
Systems' current technology is calculated using the income approach.
 
     (iv) The amount of in-process research and development costs of $60.7
million is based on (1) a preliminary valuation report prepared by an
independent appraiser, based on factors considered such as the number of
projects in process, the potential alternative future uses of those projects and
estimated future projected revenues from those projects as adjusted for the pro
rata allocation of the excess value over cost. World Access will obtain an
updated valuation of the in-process research and development as of the closing
of the Merger for use in determining the final purchase accounting for the
Merger.

                   DESCRIPTION OF WORLD ACCESS CAPITAL STOCK
 
GENERAL
 
     World Access is authorized to issue 40,000,000 shares of World Access
Common Stock, and 10,000,000 shares of preferred stock, par value $.01 per share
("World Access Preferred Stock"). If the World Access stockholders approve the
proposal to increase the number of authorized shares of World Access Common
Stock at the World Access Special Meeting, then the number of authorized shares
of World Access Common Stock will increase to 150,000,000 shares. As of November
2, 1998, there were issued and outstanding 25,675,253 shares of World Access
Common Stock and no shares of World Access Preferred Stock.
 
WORLD ACCESS COMMON STOCK
 
     The holders of World Access Common Stock are entitled to one vote for each
share held of record on all matters to be voted on by the stockholders. There is
no cumulative voting with respect to the election of directors; accordingly,
holders of a majority of the outstanding shares of World Access Common Stock can
elect all members of World Access' board of directors, and holders of the
remaining shares by themselves cannot elect any member of the board of
directors. Holders of World Access Common Stock have the exclusive right,
subject to the DGCL, to vote for election of directors and all other purposes.
 
     The holders of World Access Common Stock are entitled to receive dividends
when, as and if declared by the board of directors out of funds legally
available therefor. In the event of the liquidation, dissolution or winding up
of World Access, the holders of World Access Common Stock are entitled to share
ratably in all assets remaining available for distribution to them after payment
of liabilities and after provision has been made for each class of stock, if
any, having preference over the World Access Common Stock. Holders of shares of
World Access Common Stock, as such, have no conversion, preemptive or other
subscription rights, and there are no redemption provisions applicable to the
World Access Common Stock. All of the outstanding shares of World Access Common
Stock are fully paid and nonassessable.
 
WORLD ACCESS PREFERRED STOCK
 
     The World Access board of directors is authorized, without stockholder
approval, to issue from time to time up to 10,000,000 shares of World Access
Preferred Stock in one or more series and, with respect to each series, to
determine, subject to limitations prescribed by law, any dividend rights and
rates, any conversion or exchange rights, any rights, terms and prices of
redemption (including sinking fund provisions), any liquidation preferences, any
voting rights, and generally any other rights, preferences, privileges,
qualifications, limitations and restrictions not in conflict with the World
Access Certificate. To date, no series of World Access Preferred Stock has been
authorized or issued. World Access has no present plans to issue any shares of
World Access Preferred Stock.
 
     The issuance of shares of World Access Preferred Stock by action of the
World Access board of directors could adversely affect the voting power,
dividend rights and other rights of holders of World Access Common Stock.
Issuance of shares of a series of World Access Preferred Stock also could,
depending on the terms of such series, either impede or facilitate the
completion of a merger, tender offer or other takeover attempt. Although the
World Access board of directors is required to make a determination as to the
best interests of World Access and its stockholders when issuing shares of World
Access Preferred Stock, the board of directors could act in a manner that would
discourage an acquisition attempt or other transaction that some or a majority
of the stockholders might believe to be in the best interests of World Access or
in which stockholders might receive a premium for their World Access Common
Stock over the then-prevailing market price. Although there are currently no
plans to issue shares of World Access Preferred Stock or rights to purchase such
shares, World Access believes that the availability of the World Access
Preferred Stock will provide it with increased flexibility in structuring future
financings and acquisitions and in meeting other corporate needs that might
arise. The authorized shares of World Access Preferred Stock are available for
issuance without further action by the World Access stockholders, unless such
action is required by applicable law or the rules of any stock exchange on which
the World Access Common Stock may then be listed.

DELAWARE BUSINESS COMBINATION STATUTE
 
     Section 203 of the DGCL provides that an "interested stockholder" of a
Delaware corporation may not engage in any business combination, including
mergers or consolidations or acquisitions of additional shares of the
corporation, with the corporation for a three-year period following the date
that such stockholder becomes an interested stockholder unless (i) prior to such
time, the board of directors of the corporation approved either the business
combination or the transaction which resulted in the stockholder becoming an
interested stockholder, (ii) upon consummation of the transaction which resulted
in the stockholder becoming an "interested stockholder," the interested
stockholder owned at least 85% of the voting stock of the corporation
outstanding at the time the transaction commenced (excluding certain shares), or
(iii) at or subsequent to such time, the business combination is approved by the
board of directors of the corporation and authorized at an annual or special
meeting of stockholders by the affirmative vote of at least 66 2/3% of the
outstanding voting stock which is not owned by the interested stockholder.
Except as otherwise specified in Section 203, an interested stockholder is
defined to include (x) any person that is the owner of 15% or more of the
outstanding voting stock of the corporation, or is an affiliate or associate of
the corporation and was the owner of 15% or more of the outstanding voting stock
of the corporation at any time within three years immediately prior to the date
of determination, and (y) the affiliates and associates of any such person.
 
     Under certain circumstances, Section 203 makes it more difficult for a
person who would be an interested stockholder to effect various business
combinations with a corporation for a three-year period. World Access has not
elected to be exempt from the restrictions imposed under Section 203. The
provisions of Section 203 may encourage persons interested in acquiring World
Access to negotiate in advance with its board of directors, since the
stockholder approval requirement would be avoided if a majority of the directors
then in office approves either the business combination or the transaction which
results in any such person becoming an interested stockholder. Such provisions
also may have the effect of preventing changes in the management of World
Access. It is possible that such provisions could make it more difficult to
accomplish transactions which World Access stockholders may otherwise deem to be
in their best interests.
 
LIABILITY OF DIRECTORS
 
     The World Access Certificate provides that a director of World Access will
not be personally liable to World Access or its stockholders for monetary
damages for breach of fiduciary duty as a director, except, if required by the
DGCL as amended from time to time, for liability (i) for any breach of the
director's duty of loyalty to World Access or its 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 DGCL, which concerns unlawful
payments of dividends, stock purchases or redemptions, or (iv) for any
transactions from which the director derived an improper personal benefit.
Neither the amendment nor repeal of such provision will eliminate or reduce the
effect of such provision in respect of any matter occurring, or any cause of
action, suit or claim, that, but for such provision, would accrue or arise,
prior to such amendment or repeal.
 
TRANSFER AGENT
 
     The transfer agent for the World Access Common Stock is Continental Stock
Transfer & Trust Company, 2 Broadway, New York, New York 10004.

                        COMPARISON OF STOCKHOLDER RIGHTS
 
     The rights of World Access stockholders are currently governed by the DGCL,
the World Access Certificate and the By-Laws of World Access (the "World Access
By-Laws"). The rights of Telco Systems stockholders are currently governed by
the DGCL, the Telco Systems Certificate and the by-laws of Telco Systems (the
"Telco Systems By-Laws"). In accordance with the Merger Agreement, at the
Effective Time, each issued and outstanding share of Telco Systems Common Stock
(together with the Associated Rights) (other than (i) shares owned by Telco
Systems, World Access or Old World Access, which will be cancelled, and (ii)
shares held by persons who have perfected their appraisal rights (if applicable)
under Section 262 of the DGCL) will be converted into the right to receive the
Merger Consideration, at least 45% of which will be in the form of shares of
World Access Common Stock. Accordingly, upon consummation of the Merger, the
rights of Telco Systems stockholders who become stockholders of World Access in
the Merger will be governed by the DGCL, the World Access Certificate and World
Access By-Laws. The following is a summary of the material differences between
the current rights of World Access stockholders and the current rights of Telco
Systems stockholders.
 
     The following discussions are not intended to be complete and are qualified
by reference to the World Access Certificate, the World Access By-Laws, the
Telco Systems Certificate and the Telco Systems By-Laws. Copies of these
documents are incorporated by reference herein and will be sent to stockholders
of Telco Systems and World Access upon request. See "Incorporation of Certain
Documents by Reference."
 
AUTHORIZED CAPITAL
 
     World Access.  The authorized capital stock of World Access consists of
40,000,000 shares of World Access Common Stock, of which there were 25,675,253
shares issued and outstanding as of November 2, 1998, and 10,000,000 shares of
World Access Preferred Stock, of which none are issued and outstanding. At the
World Access Special Meeting, stockholders are being asked to approve an
increase in the number of shares of World Access Common Stock to 150,000,000.
Both common and preferred shares have par value of $0.01 per share.
 
     Telco Systems.  The authorized capital stock of Telco Systems consists of
25,000,000 shares of common stock, of which 24,000,000 are designated as Telco
Systems Common Stock and 1,000,000 are designated as Series A Junior Common

outstanding.
 
BOARD OF DIRECTORS
 
     World Access.  Pursuant to the World Access Certificate, the number of
directors of World Access is to be fixed from time to time by resolution adopted
by the World Access board of directors by at least a majority of the total
number of authorized directors most recently fixed by the World Access board of
directors. In addition, pursuant to the World Access Certificate, the number of
directors may not consist of fewer than three members and not more than twelve
members. The current size of the World Access board of directors is fixed at
six. The World Access Certificate provides for three classes of directors, with
each class elected for a term of three years and consisting as nearly as
possible of one third of the total number of directors on the World Access board
of directors. Classification of directors has the effect of making it more
difficult for stockholders to change the composition of the World Access board
of directors. World Access directors are elected by an affirmative plurality of
the number of votes cast at the annual stockholders meeting by the holders of
shares entitled to vote in the election of directors. A quorum at any meeting of
the World Access board of directors consists of a majority of the total number
of directors, and a majority of the directors present at any meeting at which a
quorum is present is required and sufficient to approve an action of the World
Access board of directors.
 
     Telco Systems.  Pursuant to the Telco Systems Certificate and the Telco
Systems By-Laws, the number of Telco Systems directors is determined from time
to time by the affirmative vote of a majority of the entire
 
                                       155
<PAGE>   167
 
Telco Systems board of directors or by the affirmative vote of a majority of
Telco Systems' voting stock. The current size of the Telco Systems board of
directors is fixed at five. The Telco Systems certificate provides for
cumulative voting for directors. Cumulative voting entitles a stockholder to
cast a number of votes equal to the number of directors to be elected multiplied
by the number of votes to which that stockholder's shares are entitled without
cumulative voting, and all such votes may be cast for a single candidate or may
be distributed among any or all of the candidates. The Telco Systems By-Laws
provide that Telco Systems directors are selected based upon the directors who
have received the greatest number votes. The Telco Systems board of directors is
not divided into classes. Telco Systems directors are elected for one-year terms
by stockholders at Telco Systems' annual meeting. A quorum at any meeting of the
Telco Systems board of directors consists of a majority of the total number of
Telco Systems directors, and a majority of the directors present at any meeting
at which a quorum is present is required and sufficient to approve an action of
the Telco Systems board of directors.
 
COMMITTEES OF THE BOARD OF DIRECTORS
 
     World Access.  The World Access By-Laws provide for the designation of
committees by resolution passed by a majority of the whole World Access board of
directors. Committees must consist of one or more of the directors, and may
exercise the powers and authority of the World Access board of directors in the
management and business affairs of the corporation. The World Access board of
directors currently has an Audit Committee and a Compensation Committee.
 
     Telco Systems.  Pursuant to the Telco Systems By-Laws, the Telco Systems
board of directors may designate an Executive Committee composed of three or
more directors appointed by the Telco Systems board of directors. To the full
extent permitted by law, the Executive Committee may be delegated by the Telco
Systems board of directors all powers of the Telco Systems board of directors
while the board is not in session. Other committees may be designated from time
to time by resolution passed by a majority of the whole Telco Systems board of
directors. To the full extent permitted by law, such committees may be delegated
by the Telco Systems board of directors all powers of the board. The Telco
Systems board of directors currently has an Audit Committee and a Compensation
Committee.
 
NEWLY CREATED DIRECTORSHIPS AND VACANCIES
 
     World Access.  Pursuant to the World Access Certificate, only a majority of
the World Access board of directors then in office, although less than a quorum,
may fill newly created or vacated board seats. The World Access Certificate also
provides that a sole remaining director may fill the vacant seats.
 
     Telco Systems.  The Telco Systems By-Laws contain provisions similar to the
World Access Certificate regarding the filling of directors vacancies.
 
REMOVAL OF DIRECTORS
 
     World Access.  The World Access Certificate provides that directors may be
removed only for cause and only by the affirmative vote of the holders of at
least a majority of the voting power of all outstanding shares of capital stock
then entitled to vote in an election of directors, voting as a single class.
 
     Telco Systems.  Neither the Telco Systems Certificate nor the Telco Systems
By-Laws includes a provision setting forth the procedure for the removal of
directors. Under the DGCL, any director or the entire board of directors of a
corporation may be removed, with or without cause, by the holders of a majority
of shares then entitled to vote at an election of directors.
 
OFFICERS
 
     World Access.  Pursuant to the World Access By-Laws, the World Access board
of directors may appoint a President, a Secretary, a Treasurer, and, if deemed
necessary, expedient or desirable by the World Access board of directors, a
Chairman of the board of directors, a Vice-Chairman of the board of directors,
an executive Vice-President, one or more other Vice-Presidents, one or more
Assistant Secretaries, one or more Assistant Treasurers, and other officers.
Except as may otherwise be provided in the resolution of the World Access board
of directors choosing an officer, no officer other than the Chairman or
Vice-Chairman of the
 
                                       156
<PAGE>   168
 
board of directors, if any, need be a director. The World Access By-Laws allow
removal of officers by the World Access board of directors with or without
cause.
 
     Telco Systems.  Pursuant to the Telco Systems By-Laws, the Telco Systems
board of directors shall appoint a Chairman of the board of directors, a
President, a Secretary and a Chief Financial Officer. The Telco Systems board of
directors may appoint a Chief Executive Officer, one or more Vice-Presidents,
one or more Assistant Secretaries and Assistant Chief Financial Officers. The
Telco Systems By-Laws provide that, notwithstanding express provisions of a
contract authorized by the Telco Systems board of directors, officers may be
removed with or without cause.
 
SPECIAL MEETINGS OF STOCKHOLDERS
 
     World Access.  Pursuant to the World Access By-Laws, a special meeting of
the World Access stockholders may be called at any time by the directors or by
any officer instructed by the directors to call the meeting.
 
     Telco Systems.  Pursuant to the Telco Systems Certificate and Telco Systems
By-Laws, a special meeting of Telco Systems stockholders may be called only by
the Chairman of the board of directors, the President, the Telco Systems board
of directors or a committee of the Telco Systems board of directors which has
been duly designated by the Telco Systems board of directors and whose powers
and authority as provided in a resolution of the Telco Systems board of
directors or in the Telco Systems By-Laws include the power to call such
meetings or by a person or persons owning, directly or indirectly, shares
possessing not less than 20% of the votes eligible to be cast for the election
of directors at the time any such determination is being made.
 
QUORUM AT STOCKHOLDER MEETINGS
 
     Pursuant to the World Access By-Laws and the Telco Systems By-Laws,
respectively, the holders of a majority of the shares of stock of the respective
corporation entitled to vote constitutes a quorum at all stockholder meetings.
In the absence of a quorum, the holders of a majority of the shares of stock
present in person or by proxy and entitled to vote may adjourn any meeting until
a quorum attends.
 
STOCKHOLDER ACTION BY WRITTEN CONSENT
 
     The World Access By-Laws and the Telco Systems Certificate, respectively,
deny the right for stockholders to act by written consent.
 
ADVANCE NOTICE OF STOCKHOLDER-PROPOSED BUSINESS AT ANNUAL MEETINGS
 
     Neither the Telco Systems Certificate, the Telco Systems By-Laws, the World
Access Certificate nor the World Access By-Laws includes a provision which
requires that advance notice be given to Telco Systems or World Access of
stockholder-proposed business to be conducted at annual meetings, except that
pursuant to the World Access Certificate, stockholders desiring to nominate
persons for election as directors at an annual meeting must notify the Secretary
of World Access in writing not less than 120 calendar days in advance of the
date which is one year later than the date of the World Access proxy statement
released to stockholders in connection with the previous year's annual meeting
of stockholders; provided, however, that if no annual meeting of stockholders
was held in the previous year or if the date of the forthcoming annual meeting
of stockholders has been changed by more than 30 calendar days from the date
contemplated at the time of the previous year's proxy statement or if the
forthcoming meeting is not an annual meeting of stockholders, then to be timely
such stockholder's notice must be so received not later than the close of
business on the tenth day following the earlier of (a) the day on which notice
of the date of the forthcoming meeting was mailed or given to stockholders by or
on behalf of World Access or (b) the day on which public disclosure of the date
of the forthcoming meeting was made by or on behalf of World Access. Any such
stockholders' notices must contain the specific information set forth in the
World Access Certificate. The DGCL also does not explicitly require that
stockholder-proposed business be the subject of an advance notice to
stockholders.
 
AMENDMENT OF GOVERNING DOCUMENTS
 
     World Access.  World Access may amend, alter, change or repeal any
provision of the World Access Certificate as permitted by the DGCL. Under the
DGCL, an amendment to a corporation's certificate of
 
                                       157
<PAGE>   169
 
incorporation requires the recommendation of a corporation's board of directors,
the approval of a majority of all shares entitled to vote thereon, voting
together as a single class, and the approval of a majority of the outstanding
stock of each class entitled to vote separately thereon unless a higher vote is
required in the corporation's certificate of incorporation (which is required by
the World Access Certificate with respect to amending the provision pertaining
to the composition and procedures regarding the World Access board of directors
(three-quarters affirmative vote of all voting stock, voting together as a
single class)). The World Access Certificate provides that the By-Laws may be
adopted, amended or repealed by the World Access board of directors. The World
Access By-Laws provide that they may be adopted, amended or repealed by the
World Access board of directors or stockholders.
 
     Telco Systems.  Pursuant to the Telco Systems Certificate, Telco Systems
reserves the right to amend or repeal any provision of the Telco Systems
Certificate as permitted under the DGCL, except as noted below. Under the DGCL,
an amendment to a corporation's certificate of incorporation requires the
recommendation of a corporation's board of directors, the approval of a majority
of all shares entitled to vote thereon, voting together as a single class, and
the approval of a majority of the outstanding stock of each class entitled to
vote thereon unless a higher vote is required in the corporation's certificate
of incorporation (which is required by the Telco Systems Certificate with
respect to amending the provisions pertaining to the denial of the right of
stockholder action by written consent (two-thirds affirmative vote of all voting
stock, voting together as a single class), certain business combinations
(two-thirds affirmative vote of all voting stock, voting together as a single
class) and amendment of the Telco Systems Certificate provision providing the
above-described exceptions (two-thirds affirmative vote of all voting stock,
voting together as a single class)). Pursuant to the Telco Systems By-Laws, the
Telco Systems board of directors has the power to adopt, amend and repeal the
Telco Systems By-Laws. Also, pursuant to the Telco Systems By-Laws, stockholders
may adopt, amend and repeal the Telco Systems By-Laws at an annual meeting,
without previous notice, or at any special meeting of stockholders, provided
that notice of such proposed amendment, repeal or adoption is given in the
notice of the special meeting, and the Telco Systems directors may exercise such
power of amendment or repeal at any meeting.
 
FAIR PRICE PROVISIONS
 
     World Access.  The World Access Certificate does not include any provision
governing the approval requirements of business combinations. Under the DGCL an
agreement of merger, or the sale, lease or exchange of all or substantially all
of a corporation's assets must be approved by the corporation's board and
adopted by the holders of a majority of the outstanding shares of stock entitled
to vote thereon.
 
     Telco Systems.  In addition to the approval requirements of business
combinations under the DGCL, the Telco Systems Certificate includes what
generally is referred to as a "fair price provision."
 
     In general, this provision of the Telco Systems Certificate provides that a
Business Combination (which is defined to include mergers, consolidations,
certain recapitalizations and the sale, lease, exchange or transfer of all or
substantially all of the assets of Telco Systems, with, to or for the benefit of
an Interested Stockholder (as defined below)) requires approval by the
affirmative vote of at least two-thirds of the votes entitled to be cast by the
holders of all then outstanding shares of voting capital stock of Telco Systems
unless the Business Combination is approved by a majority of the Disinterested
Directors (as defined below) or unless certain minimum price criteria and
procedural requirements which are intended to assure an adequate and fair price
under the circumstances are satisfied. In general, an "Interested Stockholder,"
for purposes of this provision, includes any person who is, or has announced or
publicly disclosed a plan or intention to become, the beneficial owner of voting
capital stock entitled to 20% or more of the votes. A "Disinterested Director"
is any member of the Telco Systems board of directors who neither is or is
affiliated with an Interested Stockholder and who was not directly or indirectly
a nominee of an Interested Stockholder or affiliate thereof and who either (a)
was a director of Telco Systems prior to the time any Interested Stockholder
became an Interested Stockholder or (b) is a successor of a Disinterested
Director and was nominated to succeed a Disinterested Director by a majority of
the Disinterested Directors at the time of his nomination.

RIGHTS AGREEMENT
 
     Telco Systems.  On February 19, 1997, the Telco Systems board of directors
adopted the Rights Agreement. The Telco System Rights (referred to elsewhere in
this Joint Proxy Statement/Prospectus as the "Associated Rights") provided for
thereunder represent the right to purchase one one-hundredth of a share of Telco
Systems Series A Participating Cumulative Preferred Stock, par value $0.01 per
share. One Telco Systems Right is issued for each outstanding share of Telco
Systems Common Stock. The Telco Systems Rights have certain anti-takeover
effects. The Telco Systems Rights will cause substantial dilution to a person or
group that attempts to acquire control of Telco Systems in a manner which causes
the Telco Systems Rights to become exercisable unless the offer is conditional
on the Telco Systems Rights being redeemed. Telco Systems has executed an
amendment to the Rights Agreement exempting the Merger from the potential
dilution effects of the Rights Agreement and providing that, upon consummation
of the Merger, each issued and outstanding share of Telco Systems Common Stock
(together with Associated Rights) will be converted into the right to receive
the number of shares of World Access Common Stock equal to the Exchange Ratio.
 
     World Access.  World Access has not adopted a stockholder rights or similar
plan.

      ADDITIONAL MATTERS SUBMITTED TO A VOTE OF WORLD ACCESS STOCKHOLDERS
 
ADDITIONAL PROPOSAL NO. 1 -- PROPOSAL TO AMEND THE CERTIFICATE OF INCORPORATION
OF WORLD ACCESS TO INCREASE THE NUMBER OF AUTHORIZED SHARES OF WORLD ACCESS
COMMON STOCK TO 150,000,000
 
     The board of directors of World Access has adopted a resolution unanimously
approving and recommending to World Access stockholders for their approval an
amendment to the World Access Certificate to provide therein for an increase to
150,000,000 shares of World Access Common Stock.
 
     The authorized capital stock of World Access currently consists of (i)
40,000,000 shares of World Access Common Stock, $.01 par value per share, of
which 25,675,253 were issued and outstanding as of November 2, 1998 and
approximately 2,106,812 were reserved for issuance under the World Access 1991
Stock Option Plan, the Outside Directors' Warrant Plan and the Directors'
Warrant Incentive Plan, and (ii) 10,000,000 shares of World Access Preferred
Stock with terms and designations to be determined by the board of directors of
World Access, none of which was issued and outstanding or authorized for
issuance as of the date hereof. Accordingly, as of November 2, 1998, World
Access had available for issuance 12,217,935 shares of World Access Common Stock
and 10,000,000 shares of World Access Preferred Stock.
 
     The board of directors believes the authorization of the increase in the
number of shares of World Access Common Stock is desirable to enhance the
company's flexibility in connection with possible future actions, such as public
or private offerings of shares for cash, dividends payable in stock of World
Access, stock splits, corporate mergers and acquisitions, and implementation and
continuation of employee benefit plans. Having such authorized shares for
issuance in the future would allow shares of World Access Common Stock to be
issued without the expense and delay of a special meeting of stockholders. The
additional shares of World Access Common Stock may be voting or non-voting as
determined in the board of director's sole discretion with no further
authorization by security holders required for the creation and issuance
thereof, subject to the requirements of Nasdaq that stockholder approval be
obtained for certain issuances of additional shares of World Access Common Stock
in excess of 20% of the number of shares then outstanding.
 
     The World Access board of directors is required to make any determination
to issue shares of World Access Common Stock or Preferred Stock based on its
judgment as to the best interests of the stockholders and World Access. Although
the board of directors has no present intention of doing so, it could issue
shares of World Access Common Stock or World Access Preferred Stock that could,
depending on the terms of such series, make more difficult or discourage an
attempt to obtain control of World Access by means of a merger, tender offer,
proxy contest or other means. Such shares could be used to create voting or
other impediments or to discourage persons seeking to gain control of World
Access and could also be privately placed with purchasers favorable to the board
of directors in opposing such action. In addition, the board of directors could
authorize holders of a series of World Access Common Stock or World Access
Preferred Stock to vote either separately as a class, or with the holders of
currently outstanding World Access Common Stock, on any merger, sale or exchange
of assets by World Access or any other extraordinary corporate transaction. The
mere existence of the additional authorized shares could have the effect of
discouraging unsolicited takeover attempts. The issuance of new shares also
could have a dilutive effect on the voting power of existing holders of World
Access Common Stock and on earnings per share and could be used to dilute the
stock ownership of a person or entity seeking to obtain control of World Access
should the board of directors consider the action of such entity or person not
to be in the best interest of the stockholders and World Access.
 
     While World Access may from time to time consider issuing shares of World
Access Common Stock in connection with the acquisition of related businesses or
assets, World Access currently has no plans, agreements or understandings for
issuing any shares of World Access Common Stock not currently authorized in
connection with any such acquisition other than in connection with the Merger,
and the Resurgens Transaction, nor does World Access currently have any plans,
agreements or understandings for otherwise issuing any shares of World Access
Common Stock other than pursuant to the World Access stock option plans and
director warrant plans and pursuant to the Incentive Equity Plan, as proposed
for adoption and approval in Additional Proposal No. 2 hereof. In addition,
World Access currently has no plans, agreements or understandings for issuing
any shares of a new series of World Access Common Stock or any shares of World
Access Preferred Stock. However, if this proposal is approved by the
stockholders, no assurances can be given
 
                                       160

that World Access will not consider effecting an equity offering of World Access
Common Stock or World Access Preferred Stock or otherwise issuing such stock in
the future for purposes of raising additional working capital, acquiring related
businesses or assets or otherwise. Therefore, the terms of any new series of
World Access Common Stock or any World Access Preferred Stock subject to this
proposal cannot be stated or estimated at this time.
 
     Approval of this Additional Proposal No. 1 requires the affirmative vote of
the holders of a majority of the outstanding shares of World Access Common Stock
entitled to vote at the World Access Special Meeting. If approved by the
stockholders, the amendment to the World Access Certificate will become
effective upon filing with the Secretary of the State of Delaware a Certificate
of Amendment to the World Access Certificate of Incorporation, a copy of which
is attached as Appendix F to the Joint Proxy Statement/Prospectus, which filing
is expected to take place shortly after the World Access Special Meeting.
 
     THE BOARD OF DIRECTORS OF WORLD ACCESS UNANIMOUSLY RECOMMENDS THAT THE
STOCKHOLDERS OF WORLD ACCESS VOTE "FOR" THE AMENDMENT TO THE WORLD ACCESS
CERTIFICATE TO INCREASE THE NUMBER OF AUTHORIZED SHARES OF WORLD ACCESS COMMON
STOCK TO 150,000,000.
 
ADDITIONAL PROPOSAL NO. 2 -- PROPOSAL TO ADOPT THE WORLD ACCESS, INC. 1998
INCENTIVE EQUITY PLAN
 
     The board of directors of World Access adopted on December 9, 1997, and
submits for stockholder approval, the World Access, Inc. 1998 Incentive Equity
Plan (the "Incentive Equity Plan"). A copy of the Incentive Equity Plan is
attached as Appendix G to this Joint Proxy Statement/Prospectus. The summary of
the Incentive Equity Plan which appears below is qualified by reference to the
full text of the Incentive Equity Plan.
 
     World Access has adopted the Incentive Equity Plan to attract, motivate and
retain the best available personnel for service as officers and key employees of
World Access, to provide equity ownership opportunities to these individuals and
to align the long-term interests of these people with those of stockholders.
 
     Set forth below is a description of the principal features of the Incentive
Equity Plan and the benefits that World Access has either granted under the
Incentive Equity Plan, subject to stockholder approval, or currently anticipates
granting.
 
GENERAL INCENTIVE EQUITY PLAN PROVISIONS
 
     The Incentive Equity Plan provides for the award of benefits (collectively,
"Benefits") of various types, including stock options ("Options"), restricted
shares of World Access Common Stock ("Restricted Stock"), performance shares
("Performance Shares"), and other stock-based awards. The number of shares of
World Access Common Stock which may be issued in connection with Benefits will
not exceed 5,000,000 shares. An individual's shares may be awarded in the form
of Options, Restricted Stock, Performance Shares and other stock based awards or
in any combination thereof. On December 9, 1997, the closing price of World
Access Common Stock was $23.50.
 
     The Incentive Equity Plan is administered by the Compensation Committee of
the World Access board of directors (the "Committee") which consists of two or
more members of the board of directors who are "non-employee directors", as
defined in Rule 16b-3 ("Rule 16b-3") under the Exchange Act and "outside
directors", as defined in Section 162(m) of the Code. The Compensation Committee
is currently comprised of one director and there is one vacancy on such
committee. The Committee may amend the Incentive Equity Plan at any time.
However, the Committee may not amend the Incentive Equity Plan without
stockholder approval if such amendment would (i) cause options which are
intended to qualify as incentive stock options to fail to qualify as such, (ii)
cause the Incentive Equity Plan to fail to meet the requirements of Rule 16b-3,
or (iii) violate applicable law or rules to which World Access is subject. No
Benefit may be granted under the Incentive Equity Plan on or after the tenth
anniversary date of the date the Incentive Equity Plan is approved by World
Access stockholders, but Benefits granted prior to such tenth anniversary may
extend beyond that date.
 
     Under the Incentive Equity Plan, the Committee may grant Benefits at such
times, in such amounts, and to such recipients as the Committee may determine.
Benefits may be awarded, however, only to directors, officers, employees,
independent contractors and agents of World Access and its affiliates, provided
that
                                       161
<PAGE>   173
 
incentive stock options ("ISOs") may only be granted to employees. The amendment
or termination of the Incentive Equity Plan will not adversely affect any
Benefit granted prior to such amendment or termination. However, any Benefit may
be modified or canceled by the Committee if and to the extent permitted by the
Incentive Equity Plan or applicable agreement or with the consent of the
participant to whom such Benefit was granted.
 
     Options may be either ISOs or non-qualified stock options ("NQSOs"). For
ISOs, the option price will be no less than the fair market value of the shares
of World Access Common Stock at the time the Option is granted. The other terms
of Options will be determined by the Committee, and, in the case of Options
intended to qualify as ISOs, will meet all requirements of Section 422 of the
Code.
 
     Restricted Stock is subject to forfeiture until certain conditions have
been fulfilled and/or a period of time has elapsed. Grants of Restricted Stock
shall be made at such cost as the Committee shall determine and may be issued
for no monetary consideration, subject to applicable state law. Such shares are
non-transferable until all restrictions have been satisfied. At the discretion
of the Committee, the grantee may or may not be entitled to voting and dividend
rights with respect to the Restricted Stock from the date of grant.
 
     Performance Shares are the right to receive World Access Common Stock equal
to the fair market value of the World Access Common Stock at a future date.
Generally, such right will be based upon the attainment of one or more targeted
performance goals.
 
     The Committee may also grant other awards which may be valued in whole or
in part by reference to, or otherwise based on, World Access Common Stock.
 
     If an Option expires or is terminated, surrendered, or canceled without
having been fully exercised, if Restricted Stock or Performance Shares are
forfeited, or if any other conditions result in any World Access Common Stock
not being issued, the unused shares of World Access Common Stock covered by any
such Benefit shall again be available for grant under the Incentive Equity Plan
to any participant who is not subject to Section 16 of the Exchange Act. If
there is any change in World Access Common Stock by reason of any stock split,
stock dividend, spin-off, split-up, spin-out, recapitalization, merger,
consolidation, reorganization, combination or exchange of shares, or any other
similar transaction, the number of shares of World Access Common Stock available
for grant under the Incentive Equity Plan or subject to, or granted pursuant to,
a Benefit and the price thereof, as applicable, will be appropriately adjusted
by the Committee.
 
     Except as may be provided in an applicable agreement, the terms of any
Benefits, including the pricing terms thereof, may be modified and any Benefit
may be converted, modified, forfeited, or canceled, or the restrictions or
conditions applicable to such Benefit waived or accelerated, prospectively or
retroactively, in whole or in part, by the Committee, but (unless the
participant has acted in a manner contrary to the best interests of World Access
or an affiliate of World Access) no such action may impair the rights of a
participant without his or her consent. The occurrence of a Change of Control,
as defined in Section 2.1(f) of the Incentive Equity Plan, will not limit the
Committee's authority to take any such action.
 
     Awards may be granted by the Committee in tandem. However, no Benefit may
be granted in tandem with an ISO. Upon the exercise of an Option or in the case
of any other Benefit that requires a payment to World Access, payment may be
made either (i) in cash, or (ii) with the consent of the Committee, (a) by the
surrender of all or part of a Benefit (including the Benefit being exercised),
(b) by the tender to World Access of World Access Common Stock owned by the
participant having a fair market value equal to the amount due to World Access,
(c) in other property, or (d) by any combination of the foregoing. At the time
any Benefit granted under the Incentive Equity Plan is distributed or exercised,
World Access may withhold, in cash or in shares of World Access Common Stock,
any amount necessary to satisfy withholding requirements applicable to such
distribution.
 
     Unless otherwise determined by the Committee or specified in an applicable
agreement, Benefits will not be transferable other than by beneficiary
designation, will, pursuant to the laws of descent and distribution, or pursuant
to a qualified domestic relations order, and will be exercisable during the
participant's lifetime only by such participant; except that no ISO may be
transferred or assigned pursuant to a qualified domestic relations order or
exercised, during a participant's lifetime, by the participant's guardian or
legal representative.

BENEFITS GRANTED UNDER THE INCENTIVE EQUITY PLAN
 
     All employees of World Access are eligible to participate in the Incentive
Equity Plan. The Committee has not yet determined how many employees are likely
to ultimately participate in the Incentive Equity Plan. The Committee has
awarded, however, NQSOs for an aggregate of 1,591,700 shares of World Access
Common Stock to certain senior executive officers of World Access, other key
employees of World Access and substantially all employees of NACT.
 
     The following table shows NQSOs that have been granted subject to
stockholder approval of the Incentive Equity Plan:

- ---------------
 
(1) All options have been granted at the fair market value of World Access
    Common Stock on the date of grant.
 
     In December 1997, World Access made an initial grant of 900,000 NQSO's
under the Incentive Equity Plan to its Chairman and Chief Executive Officer,
President and Chief Operating Officer, and Executive Vice President and Chief
Financial Officer. These options vest 25% on each of the first four
anniversaries from the date of grant and are exercisable at $19.00 per share,
the market price at the date of grant.
 
     In February 1998, World Access granted 568,700 NQSO's to certain key
employees, including the new President of its ATI Division (acquired in January
1998) and substantially all employees of NACT (majority interest acquired in
February 1998). These options vest 25% on each of the first four anniversaries
from the date of grant and are exercisable at $23.50 per share, the market price
at the date of grant.
 
     In June 1998, World Access granted 123,000 NQSO's to certain key employees.
These options vest 25% on each of the first four anniversaries from the date of
grant and are exercisable at $25.50 per share, the market price at the date of
grant.
 
     All of the options granted under the Incentive Equity Plan to date
accelerate upon a change of control of World Access. The consummation of the
Merger and the Resurgens Transaction will not constitute a change of control for
purposes of these options.
 
     Upon approval by the stockholders, the date of approval will become the
measurement date for purposes of computing compensation expense for the NQSO's
referred to above, if any. If the stock price as of the measurement date exceeds
the exercise prices, then the total compensation impact will be the difference
between stock price at the measurement date and the exercise prices. World
Access will record that expense ratably over the vesting period. Based on a
price of $22.25 per share, the market value of World Access Common Stock as of
November 2, 1998, World Access would record compensation expense for the
1,591,700 NQSO's of $731,250 for each of the years 1998 through 2001.
 
FEDERAL INCOME TAX CONSEQUENCES
 
     The following is a summary of certain federal income tax consequences of
the Incentive Equity Plan. Any time a distribution is made under the Incentive
Equity Plan, whether in cash or in shares of stock, World Access may withhold
from such payment any amount necessary to satisfy federal and state income tax
withholding requirements with respect to the distribution. Such withholding may
be in cash or in shares of stock.
 
                                       163
<PAGE>   175
 
     Deductibility of Benefits.  All Company deductions for Plan Benefits are
limited by Section 162(m) of the Code, which generally limits the World Access
deduction for non-performance based compensation to $1 million per year for the
World Access Chief Executive Officer and its other four most highly compensated
officers.
 
     Incentive Stock Options.  An optionee does not recognize income on the
grant of an ISO. If an optionee exercises an ISO in accordance with the terms of
the Option and does not dispose of the shares acquired within two years from the
date of the grant of the Option nor within one year from the date of exercise,
the optionee will not realize any income by reason of the exercise (except for
purposes of computing any potential alternative minimum tax ("AMT") liability as
discussed below), and World Access will be allowed no deduction by reason of the
grant or exercise. The optionee's basis in the shares acquired upon exercise
will be the amount paid upon exercise. (See the discussion below for the tax
consequences of the payment of the exercise price of an Option with stock
already owned by the optionee.) Provided the optionee holds the shares acquired
upon exercise as a capital asset at the time of sale or other disposition of the
shares, his gain or loss, if any, recognized on the sale or other disposition
will be capital gain or loss. The amount of his gain or loss will be the
difference between the amount realized on the disposition of the shares and his
basis in the shares.
 
     If an optionee disposes of the shares within two years from the date of
grant of the Option or within one year from the date of exercise ("Early
Disposition"), the optionee will recognize ordinary income at the time of such
Early Disposition which will equal the excess, if any, of the lesser of (i) the
amount realized on the Early Disposition, and (ii) the fair market value of the
shares on the date of exercise, over the optionee's basis in the shares. World
Access would be entitled to a deduction in an amount equal to such recognized
income. If an optionee disposes of the shares subsequent to one year from the
date of exercise, the excess, if any, of the amount realized on the disposition
of such shares over the fair market value of the shares on the date of exercise
will be long-term or short-term capital gain, depending upon the holding period
of the shares. If an optionee disposes of such shares for less than the
optionee's basis in the shares, the difference between the amount realized and
the optionee's basis will be a long-term or short-term capital loss, depending
upon the holding period of the shares.
 
     The excess of the fair market value of the shares at the time the ISO is
exercised over the exercise price for the shares is in the optionee's income for
AMT purposes in the taxable year of exercise. The AMT involves an additional tax
calculation applying lower rates than the regular tax calculation but adjusting
regular taxable income for certain preference items and exemption amounts.
 
     Non-Qualified Stock Options.  An optionee generally does not recognize
income at the time of the grant of a NQSO; rather, the optionee recognizes
ordinary income upon the exercise of a NQSO in an amount equal to the difference
between the fair market value of the stock on the date of exercise and the
exercise price paid for the stock. As a result of the optionee's exercise of an
NQSO, World Access will be entitled to deduct as compensation an amount equal to
the amount included in the optionee's gross income. The World Access deduction
will be taken in the taxable year in which the NQSO is exercised.
 
     Use of Shares to Exercise Option.  If an optionee exercises an Option by
surrendering stock already owned by such optionee ("Old Shares"), the following
rules apply:
 
          (i) To the extent the number of shares acquired ("New Shares") exceeds
     the number of Old Shares exchanged, the optionee will recognize ordinary
     income on the receipt of such additional shares (unless the Option is an
     ISO) in an amount equal to the fair market value of such additional shares
     less any cash paid for them, and World Access will be entitled to a
     deduction in an amount equal to such income. The basis of such additional
     shares will be equal to the fair market value of such shares (or, in the
     case of an ISO, the cash, if any, paid for the additional shares) on the
     date of exercise and the holding period for such additional shares will
     commence on the date the Option is exercised.
 
          (ii) Except as provided below, to the extent the number of New Shares
     acquired does not exceed the number of Old Shares exchanged, no gain or
     loss will be recognized on such exchange, the basis of the New Shares
     received will be equal to the basis of the Old Shares surrendered, and the
     holding period of the New Shares received will include the holding period
     of the Old Shares surrendered. However, under proposed regulations
     promulgated by the Internal Revenue Service, if the optionee exercises an
 
                                       164
<PAGE>   176
 
     ISO by surrendering Old Shares, the holding period for the New Shares will
     begin on the date the New Shares are transferred to the optionee for
     purposes of determining whether there is an Early Disposition of the New
     Shares and, if the optionee makes an Early Disposition of the New Shares,
     such optionee will be deemed to have disposed of the New Shares with the
     lowest basis first. If the optionee exercises an ISO by surrendering Old
     Shares which were acquired through the exercise of an ISO or an option
     granted under an employee stock purchase plan, and if the surrender occurs
     prior to the expiration of the holding period applicable to the type of
     option under which the Old Shares were acquired, the surrender will be
     deemed to be an Early Disposition of the Old Shares. The federal income tax
     consequences of an Early Disposition are discussed above.
 
          (iii) If the Old Shares surrendered were acquired by the optionee by
     exercise of an ISO, then, except as provided in (ii) above, the exchange
     will not constitute an Early Disposition of the Old Shares.
 
          (iv) Based upon prior rulings of the Internal Revenue Service in
     analogous areas, it is believed that if an optionee exercises an ISO and
     surrendered Old Shares and if such optionee disposes of the New Shares
     received upon exercise within two years from the date of the grant of the
     Option or within one year from the date of exercise, the following tax
     consequences would result:
 
             (a) To the extent the number of New Shares received upon exercise
        does not exceed the number of Old Shares surrendered, the disposition of
        the New Shares will not constitute an Early Disposition (unless the
        disposition is a surrender of the New Shares in the exercise of an ISO).
 
             (b) The disposition of the New Shares will constitute an Early
        Disposition to the extent the number of New Shares received upon
        exercise and disposed of exceeds the number of Old Shares surrendered.
 
     Restricted Stock and Performance Shares.  Grantees of Restricted Stock and
Performance Shares do not recognize income at the time of the grant of such
stock. However, when shares of Restricted Stock are no longer subject to a
substantial risk of forfeiture or when Performance Shares are paid, grantees
recognize ordinary income in an amount equal to the fair market value of the
stock less, in the case of Restricted Stock, the amount paid, if any, for the
stock. Alternatively, the grantee of Restricted Stock may elect (pursuant to a
"Section 83(b) election" under the Code) to recognize income upon the grant of
the stock and not at the time the restrictions lapse. World Access is entitled
to deduct an amount equal to the fair market value of the stock at the time the
grantee recognizes income related to the grant.
 
     Dividends and Dividend Equivalents.  Dividends on Restricted Stock and
dividend equivalent payments are taxable as ordinary income when paid. World
Access is entitled to deduct the amount of dividends on Restricted Stock prior
to vesting (unless the optionee makes the Section 83(b) election referred to
above) and dividend equivalent payments when such amounts are taxable to the
recipient.
 
     Change of Control.  If there is an acceleration of the vesting or payment
of Benefits and/or an acceleration of the exercisability of Options upon a
Change of Control, all or a portion of the accelerated benefits may constitute
"Excess Parachute Payments", under Section 280G of the Code. An employee
receiving an Excess Parachute Payment incurs an excise tax of 20% of the amount
of the payment in excess of the employee's average annual compensation over the
five calendar years preceding the year of the Change of Control, and World
Access is not entitled to a deduction for such excess amount.
 
     The foregoing summary of federal income tax consequences of the Incentive
Equity Plan is based on World Access' understanding of present federal tax law
and regulations and does not address any state tax ramifications. The summary
does not purport to be complete or applicable to every specific situation.
 
     THE BOARD OF DIRECTORS OF WORLD ACCESS UNANIMOUSLY RECOMMENDS THAT THE
STOCKHOLDERS OF WORLD ACCESS VOTE "FOR" THE ADOPTION OF THE WORLD ACCESS, INC.
1998 INCENTIVE EQUITY PLAN.
 
ADDITIONAL PROPOSAL NO. 3 -- PROPOSAL TO RATIFY AND APPROVE INDEMNIFICATION
AGREEMENTS WITH THE DIRECTORS AND CERTAIN OFFICERS OF WORLD ACCESS
 
                                       165
<PAGE>   177
 
     GENERAL
 
     Pursuant to authority granted by its board of directors, World Access has
entered into separate Indemnification Agreements (the "Indemnification
Agreements"), each in the form attached hereto as Appendix H, with its directors
and non-director officers at the level of Vice President and above. The board of
directors believes that the Indemnification Agreements are in the best interests
of World Access and its stockholders. In the view of the board of directors: (i)
it is important for World Access to continue to retain and attract responsible
and well-qualified individuals to serve as its directors and officers; (ii)
World Access' ability to do so is threatened by the increasing reluctance of
qualified directors and officers to assume such positions due to the increased
risk of personal liability caused by a growing risk of litigation directed
against corporate directors and officers generally and by the increasingly
adverse market for directors' and officers' liability insurance, where the
available coverage is more limited than in the past and the cost of such
insurance has increased substantially; and (iii) the Indemnification Agreements
will enhance World Access' ability to retain and attract such well-qualified
directors and officers.
 
     Although stockholder approval of the Indemnification Agreements is not
required by law or by their terms, the board of directors considers it
appropriate to submit the Indemnification Agreements to the stockholders of
World Access for their ratification and approval because the members of the
board of directors are parties to, and, therefore, the beneficiaries of the
rights contained in, the Indemnification Agreements. World Access believes that
stockholder approval will remove as a basis for challenging the enforceability
of such agreements the fact that directors may be deemed to be interested
parties under Section 144 of the DGCL. Although World Access cannot determine in
advance its position with respect to any challenge to the enforceability of the
Indemnification Agreements by a stockholder, World Access may assert stockholder
approval of the Indemnification Agreements as a defense. In addition, a
stockholder of World Access may be estopped from making a claim that the
Indemnification Agreements are invalid, if the stockholder votes in favor of
ratification and approval of the Indemnification Agreements. The Indemnification
Agreements are not conditioned on stockholder approval, and if Proposal No. 3 is
not adopted, the Indemnification Agreements will, nonetheless, remain in effect.
 
     In the case of persons who from time to time in the future become members
of the board of directors or senior officers of World Access, the board of
directors anticipates that indemnification agreements substantially in the form
of Appendix H hereto will be entered into with such new directors and officers,
subject to being authorized by the board of directors. The board of directors at
present does not expect to seek stockholder approval or ratification for any
such future agreements. A stockholder of World Access may be estopped from
making a claim that such future agreements entered into by World Access with
directors and officers of World Access are invalid, if the stockholder votes in
favor of ratification and approval of the Indemnification Agreements.
 
     The Indemnification Agreements became effective upon their execution and
delivery and will provide, in accordance with their terms, indemnification
protection to the directors and officers of World Access who are parties
thereto, with respect to actions, suits and proceedings threatened or commenced
before, as well as after, such date. The board of directors knows of no
threatened, pending or completed action, suit or proceeding to which the
Indemnification Agreements would apply.
 
     World Access has no present plans to provide indemnification protection to
its directors and officers beyond that provided by the Indemnification
Agreements.
 
     EXISTING INDEMNIFICATION AND INSURANCE PROTECTION APART FROM
INDEMNIFICATION AGREEMENTS
 
     Apart from the Indemnification Agreements, World Access currently affords
protection, by means of indemnification and insurance, to its directors and
officers. World Access is incorporated under the DGCL. Section 145 of the DGCL
provides a detailed statutory framework covering indemnification of directors
and officers against liabilities and expenses arising out of legal proceedings
brought against them by reason of their status or service as directors and
officers. Article XI of the World Access Certificate provides that World Access
shall indemnify its directors and officers to the fullest extent permitted by
the DGCL.
 
     Article XI of the World Access Certificate (which is based upon the
statutory indemnification scheme contained in Section 145 of the DGCL) provides,
in effect, that a director or officer of World Access (i) shall
 
                                       166
<PAGE>   178
 
be indemnified by World Access for all expenses of such litigation when he is
successful on the merits, (ii) shall be indemnified by World Access for the
expenses, judgments, fines and amounts paid in settlement of such litigation
(other than a derivative suit), even if he is not successful on the merits, if
he acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of World Access (and, in the case of a criminal
proceeding, had no reason to believe his conduct was unlawful), and (iii) shall
be indemnified by World Access for expenses of a derivative suit (a suit by a
stockholder by or in the right of World Access alleging a breach by a director
or officer of a duty owed to World Access) even if he is not successful on the
merits, if he acted in good faith and in a manner he reasonably believed to be
in or not opposed to the best interests of World Access, provided that no such
indemnification may be made in accordance with this clause (iii) if he is
adjudged liable to World Access, unless a court determines that, despite such
adjudication but in view of all of the circumstances, he is entitled to
indemnification. The indemnification described in clauses (ii) and (iii) above
may be made only upon a determination by a majority of a quorum of disinterested
directors, independent legal counsel or the stockholders that indemnification is
proper because the applicable standard of conduct has been met. It is possible
that indemnification pursuant to clause (ii) above would be authorized where a
director or officer of World Access has been adjudged to have been negligent or
grossly negligent, if the standard specified in clause (ii) has been satisfied.
The board of directors of World Access may also authorize the advancement of
litigation expenses to a director or officer upon receipt of an undertaking by
such director or officer to repay such expenses if it is ultimately determined
that he is not entitled to be indemnified by World Access.
 
     As permitted by the DGCL, World Access has purchased a directors' and
officers' liability insurance policy which covers certain liabilities of
directors and officers of World Access which arise out of claims based on acts
or omissions in their capacity as such and for which they are not indemnified by
World Access.
 
     LIMITATIONS OF EXISTING INDEMNIFICATION AND INSURANCE PROTECTION APART FROM
INDEMNIFICATION AGREEMENTS
 
     There are, in the judgment of the board of directors, certain limitations
inherent in the protection currently afforded to World Access' directors and
officers apart from the Indemnification Agreements. For one thing, the World
Access Certificate, including the indemnification provisions contained therein,
is subject to amendment upon obtaining the required vote of stockholders. One of
the principal purposes of the Indemnification Agreements is to provide the
directors and officers entering into the same with a continuing basis of
indemnification protection that cannot be made the subject of unilateral
amendment or revocation. As a contracting party, each indemnified director or
officer must grant his written consent to any amendment to his Indemnification
Agreement.
 
     In addition, the board of directors believes that the indemnification
provided by the World Access Certificate, which is based on the statutory
indemnification scheme, has other limitations: (i) Section 145 of the DGCL does
not provide for indemnification of a director or officer for amounts paid in
settlement of a derivative action; and (ii) the Company is under no obligation
to advance litigation expenses to a director or officer. The Indemnification
Agreements address each of these limitations. In view of the nature of a
derivative suit (a suit by a stockholder by or in the right of a corporation
alleging a breach by a director or officer of a duty owed to the corporation),
the requirement under the Indemnification Agreements of indemnification for
amounts paid in settlement of derivative actions could result in World Access
reimbursing the directors or officers who are the defendants in such a case for
amounts recovered by World Access from such defendants pursuant to a settlement
of the case.
 
     As previously mentioned, World Access maintains a directors' and officers'
liability insurance policy, and the board of directors considers this policy to
be an important part of the protection afforded by World Access to its directors
and officers. If and to the extent that a director or officer of World Access is
entitled to indemnification under his Indemnification Agreement for an amount
not covered by World Access' directors' and officers' liability insurance, then
World Access will act as a self-insurer of such amount.
 
     The Indemnification Agreements are based on the indemnification scheme set
forth in Section 145 of the DGCL which is incorporated into Article XI of the
World Access Certificate as discussed above (see "-- Limitations on Existing
Indemnification and Insurance Protection Apart From Indemnification
Agreements"), with certain changes and additions. The Indemnification
Agreements, however, do not obligate
                                       167
<PAGE>   179
 
World Access to provide indemnification coverage for actions of a director or
officer beyond what World Access is already obligated to provide by Article XI
of the World Access Certificate of Incorporation, except that the
Indemnification Agreements obligate World Access to provide indemnification for
amounts paid in settlement of a derivative action. Currently, if a director or
officer of World Access is entitled to indemnification under Article XI of the
World Access Certificate for an amount not covered by World Access' directors'
and officers' liability insurance, World Access acts as a self-insurer of such
amount. World Access has no present plans to cancel its directors' and officers'
liability insurance.
 
     In view of the foregoing limitations of the indemnification and insurance
protection currently afforded to World Access directors and officers apart from
the Indemnification Agreements, and for the reasons mentioned above, the board
of directors believes that it is in the best interests of World Access and its
stockholders to supplement such protection with the Indemnification Agreements.
 
  INDEMNIFICATION AGREEMENTS
 
     The Indemnification Agreements are based on the indemnification scheme set
forth in Section 145 of the DGCL which is incorporated into Article XI of the
World Access Certificate as discussed above (see "-- Limitations of Existing
Indemnification and Insurance Protection Apart From Indemnification
Agreements"), with certain changes and additions. The following is a summary of
such principal changes and additions provided by the Indemnification Agreements,
a form of which is attached hereto as Appendix H and incorporated herein by
reference. The description of the Indemnification Agreements is qualified in its
entirety by reference to the complete text of the form thereof. The principal
changes and additions are as set forth below.
 
     First, the Indemnification Agreements establish the presumption that the
director or officer has met the applicable standard of conduct required for
indemnification. Indemnification will be made unless the board of directors or
independent counsel determines that the applicable standard of conduct has not
been met. Following a "Change in Control" of World Access (as defined in the
Indemnification Agreements), if the person seeking indemnification so requests,
this determination must be made by independent counsel selected in the manner
provided in the Indemnification Agreements. The Indemnification Agreements
provide a detailed procedure relating to the selection of independent counsel
following a Change in Control of World Access in which the board of directors
following a Change in Control of World Access participates. Furthermore, the
Indemnification Agreements provide that the independent counsel shall not have
provided legal services to World Access, the person seeking indemnification
during the preceding five years or any other party to the proceeding giving rise
to the claim for indemnification. The board of directors, therefore, does not
believe that this provision will discourage a potential acquiror from attempting
to accomplish a Change in Control of World Access.
 
     Second, the Indemnification Agreements provide that litigation expenses
shall be advanced to a director or officer at his request provided that he
undertakes to repay the amount advanced if it is ultimately determined that he
is not entitled to indemnification for such expenses.
 
     Third, the Indemnification Agreements explicitly provide for
indemnification of amounts paid in settlement of a derivative suit.
 
     Fourth, in the event of a determination by the disinterested members of the
board of directors or independent counsel that a director or officer did not
meet the standard of conduct required for indemnification, the Indemnification
Agreements allow such director or officer to contest this determination by
petitioning a court or commencing any arbitration proceeding to be conducted by
a single arbitrator pursuant to the rules of the American Arbitration
Association to make an independent determination of whether such director or
officer is entitled to indemnification under his Indemnification Agreement.
 
     Finally, the Indemnification Agreements provide that the expenses incurred
by a director or officer in enforcing his rights under the Indemnification
Agreements shall be reimbursed by World Access.
 
     The Commission takes the position that indemnification of directors or
officers against violations of the Securities Act is against public policy and
unenforceable, and any time World Access registers securities with the
Commission it must execute an undertaking to submit to a court any such
indemnification claim arising
 
                                       168
<PAGE>   180
 
with respect to the registered securities for a determination whether the clause
is enforceable and to be bound by the court's decision. Accordingly, any claim
made by a director or officer of World Access for indemnification under an
Indemnification Agreement with respect to a claim subject to World Access'
undertaking to the Commission will have to be submitted to a court before final
payment thereunder would be made to the director or officer.
 
VOTE REQUIRED FOR RATIFICATION AND APPROVAL OF THE INDEMNITY AGREEMENTS
 
     Ratification and approval of the Indemnification Agreements requires the
affirmative vote of the holders of a majority of the shares of World Access
Common Stock present in person or represented by proxy at the Special Meeting.
 
RECOMMENDATION OF THE BOARD OF DIRECTORS
 
     The board of directors unanimously recommended that Proposal No. 3 be
submitted to the stockholders of World Access for approval. As noted herein,
however, the approval of Proposal No. 3 may benefit the directors and certain
officers of World Access. Accordingly, to the extent such persons might be
deemed to so benefit from the ratification and approval of the Indemnification
Agreements, the World Access board of directors might be viewed as having a
conflict of interest in recommending Proposal No. 3 to the stockholders for
approval.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                 JUNE 30, 1998
 
NOTE 1.  BASIS OF PRESENTATION
 
     The accompanying unaudited consolidated financial statements include the
accounts of the Company and its subsidiary companies, all of which are
wholly-owned except NACT Telecommunications, Inc. ("NACT") of which the Company
owns 67.3%. Minority interests represent the minority stockholders proportionate
share of NACT's equity. These financial statements have been prepared in
accordance with the instructions to Form 10-Q and do not include all the
information and footnotes required by generally accepted accounting principles
for complete financial statements. In the opinion of management, all adjustments
(consisting of normal recurring accruals) considered necessary for a fair
presentation of the results of the interim periods covered have been included.
For further information, refer to the audited consolidated financial statements
and footnotes included in the Company's Annual Report on Form 10-K for the year
ended December 31, 1997.
 
     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 sales and expenses during the reporting
period. Actual results could differ from those estimates.
 
     The results of operations for the three and six months ended June 30, 1998
are not necessarily indicative of the results expected for the full year.
Certain reclassifications have been made to the prior period's financial
information to conform with the presentations used in 1998.
 
NOTE 2.  ACQUISITIONS
 
ATI ACQUISITION
 
     On December 24, 1997, the Company entered into an agreement to acquire
Advanced TechCom, Inc. ("ATI"), a Wilmington, Massachusetts based designer and
manufacturer of digital microwave and millimeterwave radio systems for voice,
data and/or video applications. On January 29, 1998, the transaction was
completed in its final form whereby ATI was merged with and into Cellular
Infrastructure Supply, Inc. ("CIS"), a wholly-owned subsidiary of the Company
(the "ATI Merger").
 
     In connection with the ATI Merger, the stockholders of ATI received
approximately $300,000 in cash and 424,932 restricted shares of the Company's
common stock valued at approximately $6.5 million. The Company's policy is to
value restricted stock issued in acquisitions at the average market price of its
common stock for the three trading days prior and the three trading days
subsequent to the date economic terms of the acquisition are announced less a
discount to reflect the lack of marketability caused by trading restrictions,
size of the share issuances and other relevant factors. A discount factor of 30%
was used to value the 424,932 restricted shares, which was based on previous
sales of restricted Company common stock and independent studies regarding
discount attributable to lack of marketability. Management believes the discount
rate used to value these restricted shares was appropriate and reasonable.
 
     In addition to the shares noted above, the stockholders of ATI were issued
209,050 restricted shares of the Company's common stock. These shares were
immediately placed into escrow and will be released to the stockholders of ATI
contingent upon the realization of predefined levels of pre-tax income from
ATI's operations during calendar years 1998 and 1999. Upon issuance, the 209,050
escrowed shares were valued by the Company at par value only, or $2,091. As it
becomes probable that the conditions for release from escrow will be met, the
fair market value of the shares as measured at that time will be recorded as
additional goodwill and stockholders' equity, respectively.
 
     The acquisition of ATI has been accounted for using the purchase method of
accounting. Accordingly, the results of ATI's operations have been included in
the accompanying consolidated financial statements from February 1, 1998. The
purchase price was allocated to net assets acquired and to approximately $5.4

million of purchased in-process research and development ("R&D"). The excess of
purchase price over the fair value of net assets acquired and purchased
in-process R&D, currently estimated at approximately $2.7 million, has been
recorded as goodwill and is being amortized over a 15 year period.
 
     Purchased in-process R&D, which consisted of the value of ATI products in
the development stage that were not considered to have reached technological
feasibility as of the date of the ATI Merger, was expensed in the first quarter
of 1998 in accordance with applicable accounting rules. See Management's
Discussion and Analysis.
 
NACT ACQUISITION
 
     In the fourth quarter of 1997, the Company began a three phase acquisition
of NACT, a Provo, Utah based single-source provider of advanced
telecommunications switching platforms with integrated telephony software
applications and network telemanagement capabilities. During November and
December 1997, the Company purchased 355,000 shares of NACT common stock in the
open market for approximately $5.0 million.
 
     On December 31, 1997, the Company entered into a stock purchase agreement
with GST Telecommunications, Inc. ("GST") and GST USA, Inc. ("GST USA") to
acquire 5,113,712 shares of NACT common stock owned by GST USA, representing
approximately 63% of the outstanding shares of NACT (the "NACT Acquisition"). On
February 27, 1998, the NACT Acquisition was completed with GST USA receiving
$59.7 million in cash and 1,429,907 restricted shares of the Company's common
stock valued at approximately $26.9 million. These shares were valued at $18.80
per share, a 20% discount to the closing market price of Company common stock on
February 26, 1998. Management believes this valuation was appropriate and
reasonable based on the fact GST USA sold all 1,429,907 restricted shares at
$18.80 per share to an independent third party in a private transaction
completed on February 27, 1998.
 
     In addition, the Company issued 740,543 non-qualified options to purchase
Company common stock at $11.15 per share and 106,586 non-qualified options to
purchase Company common stock at $16.25 per share in exchange for substantially
all the options held by NACT employees, which became immediately vested in
connection with the NACT Acquisition. These options had an initial fair value of
approximately $8.4 million.
 
     On February 24, 1998, the Company entered into a merger agreement with NACT
pursuant to which the Company agreed to acquire all of the shares of NACT common
stock not already owned by the Company or GST USA. Pursuant to the terms of the
merger agreement, each share of NACT common stock will be converted into shares
of Company common stock having a value of $17.50 per share based on the average
of the daily closing price of Company common stock on the Nasdaq National Market
for a pre-defined period prior to the closing (the "Closing Price"), provided
that if the Closing Price is more than $25.52, then each share of NACT common
stock will be converted into 0.6857 shares of Company common stock. If the
Closing Price is less than $20.88, then the Company may elect to terminate the
agreement. The merger is subject to, among other things, the approval of the
NACT stockholders and the satisfaction of certain other customary conditions.
This merger is expected to be consummated in September 1998.
 
     The acquisition of the 67.3% majority interest in NACT has been accounted
for using the purchase method of accounting. Accordingly, the results of NACT's
operations have been included in the accompanying consolidated financial
statements from March 1, 1998. The purchase price of the majority interest in
NACT was allocated to 67.3% of the net assets acquired and purchased in-process
R&D. The excess of purchase price over 67.3% of the fair value of net assets
acquired and purchased in-process R&D, currently estimated at approximately
$42.8 million, has been recorded as goodwill and is being amortized over a 20
year period.
 
     During the first quarter of 1998, $44.6 million of purchased in-process
R&D, which consists of 67.3% of the value of NACT products in the development
stage that are not considered to have reached technological

feasibility as of the date of the NACT Acquisition, was expensed in accordance
with applicable accounting rules. See Management's Discussion and Analysis.
 
PRO FORMA RESULTS OF OPERATIONS
 
     On a pro forma, unaudited basis, as if the acquisitions of ATI and NACT had
occurred as of January 1, 1997, total sales, operating income, net income and
diluted net income per common share for the six months ended June 30, 1998 and
1997 would have been approximately $86.4 million and $66.9 million; $14.1
million and $7.6 million; $6.4 million and $4.1 million; and $0.30 and $0.21,
respectively. The pro forma results of operations for the six months ended June
30, 1998 would not have been materially different had the acquisitions of AIT
and NACT occurred on January 1, 1998.
 
     These unaudited pro forma results have been prepared for comparative
purposes only and are not necessarily indicative of the results of operations
which would actually have occurred had the acquisitions been in effect on the
date indicated. The portion of the ATI and NACT purchase prices allocated to
purchased in-process R&D expensed in accordance with applicable accounting rules
will not recur, therefore the pro forma results have been prepared excluding
these charges.

event that the Company deems permanent impairment of goodwill has resulted,
charges are recorded against current operations for the impairment. No
significant impairment charges have been recorded to date. See Management's
Discussion and Analysis.
 
NOTE 5.  DEBT
 
     The Company has a $10.0 million revolving line of credit with a large
European bank. As of June 30, 1998, the Company had borrowings of $4.3 million
outstanding under this facility. These borrowing were repaid to the bank in July
1998.
 
     The bank agreement, which expires in March 2001, contains standard lending
covenants including financial ratios, restrictions on dividends and limitations
on additional debt and the disposition of Company assets. Interest is paid at
the rate of prime plus 1 and 1/4% or Libor plus 2 and 1/2%, at the option of the
Company.
 
NOTE 6.  SPECIAL CHARGES
 
     Special charges in the first quarter of 1998 included $6.6 million for
costs related to the consolidation of several operations and the Company's exit
from the contract manufacturing business. The Company's AIT and circuit board
repair operations have been consolidated into a new facility in Orlando,
Florida; the Company's manufacturing operations have moved from Orlando to a new
facility in Alpharetta, Georgia; and the Company's Scottsdale, Arizona
operations have been integrated into ATI's facility in Wilmington,
Massachusetts.
 
     The special charges included $3,360,000 to cost of sales for obsolete
contract manufacturing inventories and inventories deemed obsolete or redundant
as a result of the consolidation activities. The additional charges consisted
of:

</TABLE>
 
     The consolidated program began in the first quarter of 1998 and was
completed as of June 30, 1998. No costs were included in the special charges
that are expected to derive future economic benefit to the Company. As of June
30, 1998, approximately $600,000 of accrued special charges is included in Other
current liabilities on the Company's balance sheet, which consisted primarily of
facility lease termination losses expected to be incurred. See Management's
Discussion and Analysis.
 
NOTE 7.  EARNINGS PER SHARE
 
     Effective in 1997, the Company adopted Statement of Financial Accounting
Standards No. 128 "Earnings per Share". The computation of basic earnings per
share is based on the weighted average number of common shares outstanding
during the period. The computation of diluted earnings per share is based on the
weighted average number of common shares outstanding plus, when their effect is
dilutive, potential common stock consisting of shares subject to stock options,
stock warrants and convertible notes. Potential common stock shares of 1,245,198
were included in computing diluted earnings per share for the three month period
ended June 30, 1998, and potential common stock shares of 1,959,331 and
1,440,251 were included in computing diluted earnings per share for the three
and six month periods ended June 30, 1997, respectively. A total of 1,203,786
shares of common stock held in escrow from certain acquisitions and a license
agreement were excluded from the earnings per share calculations for the three
months ended June 30, 1998 because the conditions for release of shares from
escrow had not been satisfied.
 
     Common stock issued and outstanding at June 30, 1998 and 1997 was
21,887,074 and 18,159,797 shares, respectively.

NOTE 8.  LEGAL PROCEEDINGS
 
     On August 24, 1996, Aerotel, Ltd. and Aerotel U.S.A. Inc. (collectively,
"Aerotel") commenced an action against NACT and a customer of NACT in the United
States District Court, Southern District of New York, alleging that telephone
systems manufactured and sold by NACT incorporating prepaid debit card features
infringe upon Aerotel's patent which was issued in November 1987 (the "Aerotel
Patent"). Aerotel sought injunctive relief, damages in an unspecified amount and
damages of up to three times damages found for willful infringement of the
Aerotel Patent. NACT filed an answer and Counterclaim in which it denied
infringement of the Aerotel Patent and sought judgement that the Aerotel patent
is invalid and unenforceable and that Aerotel has misused its patent in
violation of antitrust laws. NACT has denied that it has committed defamation,
unfair competition and tortuous interference with prospective business
relations. In August 1997, Aerotel amended its complaint to include as
defendants GST, GST USA, and two former executive officers of NACT. The amended
pleadings seek in excess of $18.7 million in damages and allege that GST and GST
USA have infringed the Aerotel patent, aided and abetted infringement by others,
including NACT, and participated in, and aided and abetted alleged tortuous
conduct by NACT. GST, GST USA and the two former executive officers of NACT have
served answers denying all material allegations.
 
     Under the terms of the Company's stock purchase agreement with GST, the
Company and GST have agreed to share evenly the costs of any judgement against
NACT as a result of the Aerotel litigation, including NACT's legal fees.
Subsequent to the NACT Acquisition, the Company has been actively engaged in
settlement negotiations. On July 9, 1998, the Company, GST and Aerotel entered
into a Memorandum of Understanding to settle the Aerotel litigation. As of the
date of this Report, the parties are negotiating the terms and conditions of a
final settlement agreement.
 
     The Company currently estimates that its portion of the total settlement
costs, including legal fees, will be approximately $3.3 million. Any payment
made to Aerotel is expected to be paid through the issuance of Company common
stock. The settlement costs expected to be incurred by the Company as a result
of the Aerotel litigation have been accounted for as additional NACT purchase
price as of June 30, 1998.
 
     Management expects a final Aerotel settlement agreement to be executed in
the near future. If a settlement does not occur, management believes that NACT
has valid defenses to the Aerotel claim. An unfavorable decision in this action,
however, could have a material adverse effect on the Company's financial
position.
 
NOTE 9.  PENDING ACQUISITIONS
 
RESURGENS ACQUISITION
 
     On February 12, 1998, the Company executed a letter of intent to acquire
Cherry Communications Incorporated, d/b/a Resurgens Communications Group
("RCG"), and Cherry Communications U.K. Limited ("Cherry U.K.", and together
with RCG, "Resurgens"). On May 12, 1998, the Company signed definitive
agreements to acquire Resurgens. The agreement to acquire RCG is subject to the
approval of the Bankruptcy Court. The transactions, which will be accounted for
under the purchase method of accounting, are currently expected to close in
September or October 1998.
 
     Pursuant to the terms of the agreements, the creditors of RCG and the
shareholders of Cherry U.K. will receive approximately 3.7 million restricted
shares of Company common stock in the aggregate, with an estimated fair value of
approximately $90 million. In addition, the RCG creditors and Cherry U.K.
shareholders have the right to receive additional consideration of up to 7.5
million restricted shares of Company common stock over the next two and one-half
years, contingent upon the achievement of certain EBITDA levels by Resurgens
during this timeframe. The transaction is subject to, among other things,
Resurgens exceeding pre-defined levels of monthly revenues and gross margin, the
receipt of the requisite corporate and regulatory approvals, the confirmation of
RCG's Plan of Reorganization and the approval of Company stockholders.

     RCG, currently operating under the protection of Chapter 11 of the United
States Bankruptcy Code, and Cherry U.K. are facilities-based providers of
international network access, commonly referred to in the industry as carriers'
carrier. In October 1997, John D. ("Jack") Phillips, a director of the Company,
entered into a series of agreements whereby, among other things, he became the
new Chairman and Chief Executive Officer of Resurgens. RCG filed for bankruptcy
protection shortly thereafter. WorldCom, Inc. ("WorldCom"), a major customer and
vendor of Resurgens, has subsequently provided Resurgens approximately $26
million of direct financial support through a debtor in possession facility and
additional financial support, primarily through trade credits.
 
     In April 1998, the Company purchased approximately $3.6 million of
switching equipment which has been consigned to Resurgens. Upon its acquisition
of Resurgens, the Company will account for this equipment as part of its
investment in Resurgens. If the acquisition is not consummated, the Company
expects to negotiate an arms-length sale of the equipment to Resurgens or
another customer. This equipment is included in Other assets on the Company's
June 30, 1998 balance sheet.
 
TELCO ACQUISITION
 
     On June 4, 1998, the Company entered into a definitive Agreement to merge
with Telco Systems, Inc. ("Telco") (the "Merger").
 
     As a result of the Merger, each outstanding share of Telco common stock
shall be converted into the right to receive that number of shares of Company
common stock equal to the quotient of $17.00 divided by the average daily
closing price of Company common stock as reported on Nasdaq on each of the
twenty consecutive trading days ending on the second business day prior to the
date of the Merger (the "Average Closing Price"), provided that if the Average
Closing Price is more than $36.00 per share, then each share of Telco common
stock will be converted into .4722 shares of Company common stock and if the
Average Closing Price is less than $29.00 per share, then each share of Telco
common stock will be converted into .5862 shares of Company common stock. Based
on the Company's current stock price as of the date of this Report, the shares
issued in connection with the Merger will be valued at approximately $200
million.
 
     The Merger is intended to constitute a reorganization under Section 368(a)
of the Internal Revenue Code of 1986, as amended, and will be accounted for as a
purchase. The purchase price will be allocated to the net assets acquired and to
approximately $65 million of purchased in-process R&D. Purchased in-process R&D,
which consists of the value of Telco's products in the development stage that
are not considered to have reached technological feasibility, will be expensed
upon completion of the Merger.
 
     The consummation of the Merger is subject to (i) clearance under the
Hart-Scott-Rodino Improvements Act of 1976, as amended, (ii) the approval by the
respective stockholders of the Company and Telco, (iii) the approval by the
stockholders of the Company of an increase in the authorized shares of common
stock of such corporation, and (iv) the satisfaction or waiver of customary
conditions. The Merger is expected to be consummated in September or October
1998.

position of World Access, Inc. and its subsidiaries at December 31, 1997 and
1996, and the results of their operations and their cash flows for each of the
three years in the period ended December 31, 1997, in conformity with generally
accepted accounting principles. 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 of these statements in accordance with generally accepted auditing
standards which require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE A:  GENERAL
 
NATURE OF BUSINESS
 
     World Access, Inc. and its wholly-owned subsidiaries (the "Company")
operate in one business segment as a provider of systems, products and services
to the global telecommunications marketplace. The Company develops, manufactures
and markets wireline and wireless switching, transport and access products
primarily for the United States, Caribbean Basin and Latin American
telecommunications markets. The Company's products allow telecommunications
service providers to build and upgrade their central office and outside plant
networks in order to provide a wide array of voice, data and video services to
their business and residential customers. The Company offers digital switches,
cellular base stations, fixed wireless local loop systems, intelligent
multiplexers, microwave and millimeterwave radio systems and other
telecommunications network equipment. The products offered by the Company
include those manufactured by the Company as well as those manufactured by other
telecommunications equipment companies. To support and complement its product
sales, the Company also provides its customers with a broad range of design,
engineering, manufacturing, testing, installation, repair and other value-added
services.
 
BASIS OF PRESENTATION
 
     The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiaries from their effective dates of acquisition (see
"Note B"). All material intercompany accounts and transactions are eliminated in
consolidation.
 
     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 could differ from those estimates.
 
     The estimated fair value of financial instruments has been determined by
the Company using available market information and appropriate valuation
methodologies. However, considerable judgment is required in interpreting data
to develop the estimates of fair value. Accordingly, the estimates presented
herein are not necessarily indicative of the amounts that the Company could
realize in a current market exchange. The fair value estimates presented herein
are based on pertinent information available to management as of the respective
balance sheet dates. Although management is not aware of any factors that would
significantly affect the estimated fair value amounts, such amounts have not
been comprehensively revalued for purposes of these financial statements since
that date and current estimates of fair value may differ significantly from the
amounts presented herein.
 
     The fair values of cash equivalents, accounts receivable, accounts payable
and accrued expenses approximate the carrying values due to their short-term
nature. The fair values of long-term debt are estimated based on current market
rates and instruments with the same risk and maturities and approximate the
carrying value.
 
REVENUE RECOGNITION
 
     In general, revenues are recognized when the Company's products are shipped
or services are rendered. Occasionally, the Company will enter into long-term
contracts which require percentage of completion accounting treatment.
 
     During 1997, the Company recognized approximately $5.3 million of revenues
under the percentage of completion method. Of this amount, approximately $2.5
million represents costs and estimated earnings in excess of billings and is
included in Other current assets on the Company's December 31, 1997 balance
sheet.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
SIGNIFICANT CUSTOMERS
 
     A portion of the Company's total sales have been derived from significant
customers. During 1997, no customer individually accounted for 10.0% of the
Company's total sales. During 1996, one customer accounted for 10.9% of total
sales. During 1995, two customers individually accounted for 22.7% and 15.1% of
total sales.
 
CASH AND EQUIVALENTS
 
     Cash equivalents include demand deposits with banks and all highly liquid
investments with original maturities of three months or less.
 
ACCOUNTS RECEIVABLE
 
     Accounts receivable are presented net of an allowance for doubtful accounts
of $237,000, $265,000, and $208,000 at December 31, 1997, 1996, and 1995,
respectively.
 
INVESTMENT IN AFFILIATE
 
     During November and December 1997, the Company purchased 355,000 shares of
NACT Telecommunications, Inc. ("NACT") common stock in the open market for
approximately $5.0 million.
 
     On December 31, 1997, the Company entered into a stock purchase agreement
with GST Telecommunications, Inc. ("GST") and GST USA, Inc. ("GST USA"), a
wholly owned subsidiary of GST, to acquire 5,113,712 shares of NACT common stock
owned by GST USA. On February 27, 1998, the Company completed this purchase
increasing its ownership of NACT to approximately 67.3%. On February 24, 1998,
the Company executed a definitive merger agreement with NACT to acquire the
remaining 32.7% of NACT common shares (see "Note N").
 
EARNINGS PER SHARE
 
     Effective in 1997, the Company adopted Statement of Financial Accounting
Standards No. 128 "Earnings per Share". The computation of basic earnings per
share is based on the weighted average number of common shares outstanding
during the period. The computation of diluted earnings per share is based on the
weighted average number of common shares outstanding plus, when their effect is
dilutive, potential common stock consisting of shares subject to stock options,
stock warrants and convertible notes. Potential common stock shares of
1,465,376, 1,485,562 and 1,224,306 as of December 31, 1997, 1996 and 1995,
respectively, have been included in computing diluted earnings per share. A
total of 994,736, 401,267 and 895,744 shares of common stock for the years ended
December 31, 1997, 1996 and 1995, respectively, held in escrow from certain
acquisitions (see "Note B"), the Company's initial public offering (see "Note
H") and the TCSI license agreement (see "Note E"), were excluded from the
earnings per share calculations because the conditions for release of shares
from escrow had not been satisfied.
 
RECLASSIFICATIONS
 
     Certain items in the prior year consolidated financial statements have been
reclassified to conform to the current presentation.
 
NOTE B:  ACQUISITIONS
 
AIT ACQUISITION
 
     On May 17, 1995, the Company entered into an agreement to acquire AIT, Inc.
("AIT"), a Lakeland, Florida based provider of new and used Northern Telecom
switching systems and related circuit boards to the telecommunications industry.
On July 11, 1995, the transaction was completed in its final form whereby AIT
was merged with and into Restor-AIT, Inc., a wholly-owned subsidiary of the
Company (the "AIT Merger"). In connection with the AIT Merger, the sole
stockholder of AIT received 685,970 restricted shares of the Company's common
stock. These shares had an initial fair value of approximately $1.7 million.
 
                                      F-20

                      WORLD ACCESS, INC. AND SUBSIDIARIES
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     In July 1995, the Company loaned the sole stockholder of AIT $1.3 million
in cash in connection with a $2,330,000 interest bearing promissory note
executed as an integral part of the merger agreement between the two companies.
An additional $1,030,000 was to be loaned to the stockholder as specific
accounts receivable, notes receivable and inventories on AIT's May 17, 1995
balance sheet were collected and/or realized by the Company. As of December 31,
1996, the Company had loaned an aggregate of $2,319,134 to the stockholder. The
principal balance of the note as of December 31, 1996 was $571,634, which was
fully collateralized by shares of the Company's common stock pledged by the sole
stockholder. As a result of this pledge agreement, the note receivable from the
stockholder was accounted for as a reduction of stockholders' equity. As of
December 31, 1997, the amounts due from the stockholder were paid in full.
 
     In addition to the 685,970 shares noted above, the sole stockholder of AIT
was issued 637,308 restricted shares of the Company's common stock. These shares
were immediately placed into escrow, and along with $2,330,000 in potential cash
payments, were to be released to the sole stockholder over a two year period
ending August 15, 1997 contingent upon the realization of predefined levels of
gross profit from AIT's operations during this same period. To the extent cash
consideration was paid, the sole stockholder was immediately required to repay
the equivalent amount of borrowings outstanding under the promissory note
described above.
 
     Upon issuance, the 637,308 escrowed shares were valued by the Company at
par value only, or $6,373. As it became probable that the conditions for release
from escrow would be met, the fair market value of the shares as measured at
that time, along with any contingent cash payment earned, were recorded as
additional goodwill and stockholders' equity, respectively.
 
     As of December 31, 1997, the Company had released all 637,308 shares from
escrow and paid additional cash consideration of $2,330,000 based on AIT's gross
profit performance. Based on AIT's pre-tax income performance, an additional
$3.1 million in purchase price was paid to the sole stockholder in August 1997
in the form of 121,182 restricted shares of the Company's common stock. The net
effect of the above has been to increase goodwill and stockholder's equity by
approximately $8.0 million as of December 31, 1997.
 
     As part of a final purchase price settlement agreement entered into in
August 1997, the sole stockholder of AIT pledged 280,509 shares of the Company's
common stock to the Company to effectively guarantee the collectibility of
certain AIT accounts receivable. During the fourth quarter of 1997 and the first
quarter of 1998, these accounts receivable were paid in full through cash
proceeds from the sale of these pledged shares.
 
     The acquisition of AIT has been accounted for using the purchase method of
accounting. Accordingly, the results of AIT's operations have been included in
the accompanying consolidated financial statements from May 17, 1995, the
effective date of acquisition. The purchase price was allocated to the assets
acquired and liabilities assumed based on their estimated fair values as of the
date of acquisition. The excess of purchase price over the fair value of net
assets acquired, approximately $11.6 million, has been recorded as goodwill and
is being amortized over a 15 year period.
 
WESTEC ACQUISITION
 
     On October 2, 1995, the Company entered into an agreement to acquire Westec
Communications, Inc. ("Westec"), a Scottsdale, Arizona based provider of
wireless systems and repair services to the cable television and
telecommunications industries. On October 31, 1995, the transaction was
completed in its final form whereby Westec was merged with and into
Restor-Westec, Inc., a wholly-owned subsidiary of the Company (the "Westec
Merger"). Restor-Westec, Inc. subsequently changed its name to Westec
Communications, Inc. In connection with the Westec Merger, the sole stockholder
of Westec received $550,000 and 272,050 restricted shares of the Company's
common stock. These shares had an initial fair value of approximately $900,000.
 
     As part of the Westec Merger agreement, the sole stockholder of Westec may
also receive $1.0 million in additional purchase price (the "Westec Additional
Consideration") contingent upon the realization of
 
                                      F-21

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
predefined levels of pre-tax income from Westec's operations during five
calendar years beginning in 1996. This additional consideration may be paid, at
the option of the Company, in the form of cash or restricted shares of the
Company's common stock valued at the then current market prices. If earned, the
Westec Additional Consideration will be capitalized as additional goodwill and
stockholders' equity, respectively.
 
     In connection with the Westec Merger, the Company entered into a
Compensation Agreement with Sherman Capital Group L.L.C. ("Sherman"), a merchant
banking firm that had a pre-existing letter of intent to acquire Westec.
Pursuant to the Compensation Agreement, Sherman received $100,000 and 45,000
restricted shares of the Company's common stock. These shares had an initial
fair value of approximately $150,000. The compensation paid to Sherman has been
accounted for as part of the purchase price of Westec. In addition, 200,000
restricted shares of the Company's common stock were placed in escrow and may be
released to Sherman in installments over a four year period on February 15 of
each year beginning on February 15, 1997, contingent upon the realization of
predefined levels of pre-tax income from Westec's operations. Upon issuance, the
200,000 escrowed shares were valued by the Company at par value only, or $2,000.
As it becomes probable that the conditions for release from escrow will be met,
the fair market value of the shares as measured at that time will be recorded as
additional goodwill and stockholders' equity.
 
     The first measurement period for purposes of releasing escrowed shares and
paying Westec Additional Consideration was January 1, 1996 to December 31, 1996.
Westec's pre-tax income for the first measurement period failed to meet the
performance criterion required to earn any additional consideration. In
reviewing Westec's pre-tax performance for the second performance period,
January 1, 1997 to December 31, 1997, the Company determined that the earn-out
performance criterion was met. Accordingly, 50,000 escrowed shares were
accounted for as if released to Sherman and $200,000 of Westec Additional
Consideration was accounted for as if paid to the sole stockholder of Westec as
of December 31, 1997. The net effect of this accounting was to increase goodwill
and stockholders equity by approximately $1.0 million and $800,000,
respectively. The escrowed shares were released and Westec Additional
Consideration was paid on February 15, 1998.
 
     The acquisition of Westec has been accounted for using the purchase method
of accounting. Accordingly, the results of Westec's operations have been
included in the accompanying consolidated financial statements from October 2,
1995, the effective date of acquisition. The purchase price was allocated to the
assets acquired and liabilities assumed based on their estimated fair values as
of the date of acquisition. The excess of purchase price over the fair value of
net assets acquired, currently estimated at approximately $2.4 million, has been
recorded as goodwill and is being amortized over a 15 year period.
 
SUNRISE ACQUISITION
 
     In February 1996, the Company entered into an agreement to acquire Comtech
Sunrise, Inc. ("Sunrise"), a Livermore, California based manufacturer of
multiplexers, digital loop carriers and other intelligent transport and access
products. On June 18, 1996, after a mandatory registration process was completed
in the State of California, the transaction was completed in its final form
whereby Sunrise was merged with and into Restor-Comtech, Inc., a wholly-owned
subsidiary of the Company (the "Sunrise Merger"). Restor-Comtech, Inc.
subsequently changed its name to Sunrise Sierra, Inc. In connection with the
Sunrise Merger, the stockholders of Sunrise received approximately $100,000 in
cash and 385,481 shares of the Company's common stock. These shares had an
initial fair value of approximately $2.3 million.
 
     In addition to the 385,481 shares noted above, the stockholders of Sunrise
were issued 211,765 restricted shares of the Company's common stock. These
shares were immediately placed into escrow, and along with $1.8 million in
additional purchase price (the "Sunrise Additional Consideration"), will be
released to the stockholders of Sunrise contingent upon the realization of
predefined levels of pre-tax income from Sunrise's operations during three
one-year periods beginning January 1, 1996. The Sunrise Additional Consideration
may be paid, at the option of the Company, in the form of cash or restricted
shares of the Company's common stock valued at the then current market prices.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     Upon issuance, the 211,765 escrowed shares were valued by the Company at
par value only, or $2,118. As it becomes probable that the conditions for
release from escrow will be met, the fair market value of the shares as measured
at that time, along with any Sunrise Additional Consideration earned, will be
recorded as additional goodwill and stockholders' equity, respectively.
 
     The first measurement period for purposes of releasing escrowed shares and
paying Sunrise Additional Consideration was January 1, 1996 to December 31,
1996. In reviewing Sunrise's pre-tax income performance, the Company determined
that the earn-out performance criterion was met. Accordingly, 58,823 escrowed
shares were accounted for as if released and $500,000 of Sunrise Additional
Consideration was accounted for as if paid (in the form of 58,118 restricted
shares of Company common stock) as of December 31, 1996. The net effect of this
accounting was to increase goodwill and stockholders' equity by approximately
$700,000. The escrowed shares were released and additional shares were issued on
February 15, 1997. The second measurement period was January 1, 1997 to December
31, 1997. Sunrise's pre-tax income failed to meet the performance criterion
required to earn any additional consideration for that period.
 
     The acquisition of Sunrise has been accounted for using the purchase method
of accounting. Accordingly, the results of Sunrise's operations have been
included in the accompanying consolidated financial statements from January 1,
1996, the effective date of acquisition as defined in the definitive agreement
and plan of merger. The purchase price was allocated to the assets acquired and
liabilities assumed based on their estimated fair values as of the date of
acquisition. The excess of purchase price over the fair value of net assets
acquired, currently estimated at approximately $2.3 million, has been recorded
as goodwill and is being amortized over a 15 year period.
 
CIS ACQUISITION
 
     On March 11, 1997, the Company entered into an agreement to acquire
Cellular Infrastructure Supply, Inc. ("CIS"), a Burr Ridge, Illinois based
provider of new and/or upgraded equipment and related design, installation and
technical support services to cellular, PCS and other wireless service
providers. On March 27, 1997, the transaction was completed in its final form
whereby CIS was merged with and into CIS Acquisition Corp., a wholly-owned
subsidiary of the Company (the "CIS Merger"). CIS Acquisition Corp. subsequently
changed its name to Cellular Infrastructure Supply, Inc. In connection with the
CIS Merger, the three stockholders of CIS received $3.5 million in cash and
440,874 restricted shares of the Company's common stock. These shares had an
initial fair value of approximately $2.6 million.
 
     In addition to the 440,874 shares noted above, the stockholders of CIS were
issued 845,010 restricted shares of the Company's common stock. These shares
were immediately placed into escrow, and along with $6.5 million in additional
purchase price (the "CIS Additional Consideration"), will be released and paid
to the stockholders of CIS contingent upon the realization of predefined levels
of pre-tax income from CIS's operations during three one-year periods beginning
January 1, 1997.
 
     Upon issuance, the 845,010 escrowed shares were valued by the Company at
par value only, or $8,450. Once conditions for release from escrow have been
met, the fair market value of the shares as measured at that time, along with
any CIS Additional Consideration earned, will be recorded as additional goodwill
and stockholders' equity, respectively.
 
     The first measurement period for purposes of releasing escrowed shares and
paying CIS Additional Consideration was January 1, 1997 to December 31, 1997. In
reviewing CIS's pre-tax income performance as of April 30, 1997, the Company
determined that it was highly probable that the conditions for release and
payment for the first period would be met. Accordingly, 317,427 escrowed shares
were accounted for as if released and $3.5 million of CIS Additional
Consideration was accounted for as if paid as of April 30, 1997. The net effect
of this accounting was to increase goodwill and stockholders' equity by
approximately $6.5 million and $3.0 million, respectively, as of April 30, 1997.
These escrowed shares were released and CIS Additional Consideration was paid to
the former stockholders of CIS on February 15, 1998. The $3.5 million

of CIS Additional Consideration earned is included in Purchase price payable on
the Company's December 31, 1997 balance sheet.
 
     The acquisition of CIS has been accounted for using the purchase method of
accounting. Accordingly, the results of CIS's operations have been included in
the accompanying consolidated financial statements from January 1, 1997, the
effective date of acquisition as defined in the definitive agreement and plan of
merger. The purchase price was allocated to the assets acquired and liabilities
assumed based on their estimated fair values as of the date of acquisition. The
excess of purchase price over the fair value of net assets acquired, currently
estimated at approximately $12.5 million, has been recorded as goodwill and is
being amortized over a 15 year period.
 
GALAXY ACQUISITION
 
     On July 29, 1997, the Company entered into a letter of intent to acquire
Galaxy Personal Communications Services, Inc. ("Galaxy"), a Norcross, Georgia
based provider of system design, implementation, optimization and other
value-added radio engineering and consulting services to PCS, cellular and other
wireless telecommunications service providers. On August 26, 1997, the
transaction was completed in its final form whereby Galaxy was merged with and
into Galaxy Acquisition Corp., a wholly-owned subsidiary of the Company (the
"Galaxy Merger"). Galaxy Acquisition Corp. subsequently changed its name to
Galaxy Personal Communications Services, Inc. In connection with the Galaxy
Merger, the former stockholders of Galaxy received approximately $1.2 million in
cash and 262,203 restricted shares of the Company's common stock. These shares
had an initial fair value of approximately $4.2 million.
 
     In addition to the 262,203 shares noted above, the former Galaxy
stockholders were issued 131,101 restricted shares of the Company's common
stock. These shares were immediately placed into escrow, and along with $3.5
million in additional consideration (the "Galaxy Additional Consideration"),
will be released and paid to the former stockholders of Galaxy contingent upon
the realization of predefined levels of pre-tax income from Galaxy's operations
during four measurement periods between July 1, 1997 and December 31, 2000. The
Galaxy Additional Consideration may be paid, at the option of the Company, in
the form of cash or restricted shares of the Company's common stock valued at
the then current market prices.
 
     Upon issuance, the 131,101 escrowed shares were valued by the Company at
par value only, or $1,311. Once conditions for release from escrow have been
met, the fair market value of the shares as measured at that time, along with
any Galaxy Additional Consideration earned, will be recorded as additional
goodwill and stockholders' equity, respectively.
 
     The first measurement period for purposes of releasing escrowed shares and
paying Galaxy Additional Consideration was July 1, 1997 to December 31, 1997. In
reviewing Galaxy's pre-tax income performance, the Company determined that the
earn-out performance criterion was met. Accordingly, 15,215 escrowed shares were
accounted for as if released and $400,000 of Galaxy Additional Consideration (in
the form of 14,901 restricted shares of Company common stock) were accounted for
as if paid as of December 31, 1997. The net effect of this accounting was to
increase goodwill and stockholders' equity by approximately $500,000 as of
December 31, 1997. These escrowed shares were released and additional shares
were issued to the former stockholders of Galaxy on February 15, 1998.
 
     The acquisition of Galaxy has been accounted for using the purchase method
of accounting. Accordingly, the results of Galaxy's operations have been
included in the accompanying consolidated financial statements from July 1,
1997, the effective date of acquisition as defined in the definitive agreement
and plan of merger. The purchase price was allocated to the assets acquired and
liabilities assumed based on their estimated fair values as of the date of
acquisition. The excess of purchase price over the fair value of net assets
acquired, currently estimated at approximately $5.1 million, has been recorded

PRO FORMA RESULTS OF OPERATIONS
 
     On a pro forma, unaudited basis, as if the acquisitions of AIT, Westec and
Sunrise had occurred as of January 1, 1995, total sales, operating income, net
income and diluted net income per common share for the year ended December 31,
1995 would have been approximately $38,100,000, $2,200,000, $1,800,000 and
$0.17, respectively.
 
     On a pro forma, unaudited basis, as if the acquisition of CIS had occurred
as of January 1, 1996, total sales, operating income, net income and net income
per diluted common share for the year ended December 31, 1996 would have been
approximately $63,810,000, $10,680,000, $8,520,000, and $0.57, respectively. The
results of operations for Galaxy during 1996 and the first six months of 1997
were not material and therefore are not included in the pro forma disclosure.

NOTE E:  TECHNOLOGY LICENSES
 
     In March 1996, the Company entered into a memorandum of understanding with
International Communication Technologies, Inc. ("ICT") and Eagle Telephonics,
Inc. ("Eagle") to manufacture, market and sell a new modular, digital central
office switch developed by Eagle. In July 1996, a long-term technology licensing
agreement was executed by all three parties. As consideration for this license,
the Company paid Eagle $250,000 in cash and provided it $450,000 of
manufacturing services. The license fees paid Eagle will be amortized to expense
in connection with the first 300,000 lines of phone service provided for within
the switches sold by the Company, i.e. approximately $2.50 per line. In addition
to the up-front consideration, the Company agreed to pay ICT certain royalties
based on future sales of the switch by the Company. During 1997, the Company
expensed license fees and royalties of approximately $200,000 in connection with
lines sold during the year. In connection with this license and the up-front
consideration paid, the Company received 1.2 million restricted shares of Eagle
common stock. The fair value of these shares was not material as of December 31,
1997.
 
     In December 1996, the Company executed a technology licensing agreement
with TCSI Corporation ("TCSI") that grants the Company the perpetual rights to
incorporate TCSI's spread spectrum Code Division Multiple Access ("CDMA") based
wireless technology into the Company's products sold throughout the world. Under
the terms of the agreement, the Company also has the rights to use the
technology covered by seven TCSI patents, all of which address digital data
signals and wireless communication systems. As total consideration for this
license, TCSI was paid $50,000 in cash and 25,000 shares of restricted Company
common stock. These shares had an initial fair value of approximately $150,000.
In addition to the 25,000 shares noted above, TCSI was issued 25,000 shares of
restricted common stock. These shares were immediately placed into escrow and
will be released to TCSI upon the earlier of the first commercial use of

     Goodwill is being amortized on a straight-line basis over a 15 year period.
The Company reviews the net carrying value of goodwill on a regular basis, and
if deemed necessary, charges are recorded against current operations for any
impairment in the value of these assets. No significant impairment charges have
been recorded to date. Goodwill is removed from the books when fully amortized.

     Interest paid for the years ended December 31, 1997, 1996 and 1995 was
$57,000, $352,000 and $507,000, respectively.
 
CONVERTIBLE SUBORDINATED NOTES
 
     On October 1, 1997, the Company sold $100.0 million in aggregate principal
amount of convertible subordinated notes (the "Notes") under Rule 144A of the
Securities Act of 1933. The Notes bear interest at the rate of 4.5% per annum,
are convertible into Company common stock at an initial price of $37.03 per
share and mature on October 1, 2002. Interest on the Notes is payable on April 1
and October 1 of each year, commencing on April 1, 1998. The Notes are general
unsecured obligations of the Company and are subordinate in right of payment to
all existing and senior indebtedness. The Company received $97.0 million from
the sale of the Notes, after the application of the initial purchasers' discount
fees of $3.0 million.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     In addition to the Notes sold on October 1, 1997, the Company granted the
initial purchasers an option to purchase up to an additional $15.0 million in
Notes to cover over-allotments. On October 28, 1997, the initial purchasers
exercised the over-allotment option in full and the Company received an
additional $14,550,000, after the application of the initial purchasers'
discount fees of $450,000.
 
     The discount fees and legal, accounting, printing and other expenses (the
"Debt issuance costs") related to the Notes offering amounted to approximately
$4.0 million, and are being amortized to expense over the five year term of the
Notes. During 1997, the Company recognized approximately $200,000 of debt
issuance cost amortization related to the Notes. Debt issuance costs of
approximately $3.8 million are included in Other assets on the Company's
December 31, 1997 balance sheet.
 
BANK DEBT
 
     In December 1996, the Company's agreement with a large European bank was
amended to increase its revolving line of credit to $10 million. Borrowings
under the line are secured by a first lien on substantially all the assets of
the Company. The bank agreement, which expires in March 2001, contains standard
lending covenants including financial ratios, restrictions on dividends and
limitations on additional debt and the disposition of Company assets. Interest
is paid at the rate of prime plus 1 1/4% or LIBOR plus 2 1/2%, at the option of
the Company.
 
     Prior to 1996, the Company's principal source of debt financing since May
1992 has been with this European bank. In connection with operating losses
experienced by the Company, restructuring programs implemented by the Company
and violations of financial covenants established by the bank, the bank
agreement was amended several times during 1992 through 1994 to defer principal
payments and restructure financial covenants. In consideration for the original
credit facility and the significant concessions provided during this period, the
bank received warrants to purchase 360,000 shares of the Company's common stock
at its then current market price of $1.25 per share.
 
     In July 1995, the Company received a new $2 million revolving line of
credit from the bank. In consideration for the line of credit and a reduced
interest rate, the Company paid the bank a $30,000 origination fee and issued
the bank warrants to purchase 100,000 shares of the Company's common stock at
its then current market price of $3.82 per share on or prior to October 31,
1999. In October 1995, the bank paid the Company $832,000 to exercise all
460,000 warrants (see "Note I").
 
     In October 1996, in connection with a secondary public equity offering
completed by the Company, the Company paid the bank $3.9 million to pay off the
outstanding principal balance on its term loan.
 
NOTE H:  STOCKHOLDERS' EQUITY
 
     During September and October 1996, 3,487,500 shares of Company common stock
were sold in a secondary public offering at a price of $8.00 per share. The
Company received $26,156,250 from this offering, net of underwriting discounts.
The Company incurred additional expenses of approximately $825,000 in connection
with this offering.
 
     During June and July 1995, 1,168,000 restricted shares of the Company's
common stock were sold in a private placement for a gross consideration of
$2,920,000, or its then current market price of $2.50 per share. Participants in
the offering also received warrants to purchase a total of 1,168,000 of
additional shares of restricted common stock at $3.50 per share on or prior to
June 30, 2000. Approximately $275,000 of the offering was purchased by the
directors and management of the Company. In October 1995, stockholders paid the
Company approximately $4.1 million to exercise all warrants issued as a result
of the private offering (see "Note I").
 
     In connection with the Company's initial public offering in August 1991,
all of the existing holders of the Company's common stock placed in escrow an
aggregate of 672,419 shares of the Company's common stock. As of August 12,
1996, the termination date of the escrow agreement, the conditions for release
of the shares

had not been met. Accordingly, the 672,419 escrowed shares of Company common
stock were returned to the Company and became authorized but unissued shares.
 
NOTE I:  STOCK WARRANTS AND OPTIONS
 
STOCK WARRANTS
 
     In connection with various financial transactions completed by the Company
during 1992 to 1995, equity investors (see "Note H"), debtors (see "Note G") and
certain consultants were issued warrants to purchase shares of the Company's
common stock in the future. All of these warrants had exercise prices that were
set at or above the then current market price of the Company's common stock at
the respective dates of grant.
 
     In October 1995, the Company raised approximately $6.5 million of new
capital through the exercise of previously issued warrants and non-qualified
options to purchase 2,433,853 shares of the Company's common stock. Of the $6.5
million raised, approximately $1.6 million was invested by the directors,
management and the principal lender of the Company. In exercising their warrants
or options, investors had the option of paying cash or executing an 8% interest
bearing note payable to the Company. Approximately $2.4 million of the total
proceeds was paid in cash and $4.1 million through notes. The notes were paid in
full by March 29, 1996.
 
     As of December 31, 1997, there were no warrants outstanding to purchase
Company common stock except for the Director warrant plans discussed below.
 
DIRECTOR WARRANT PLANS
 
     In December 1994, in an effort to attract and retain experienced executives
to serve as outside directors for the Company, the Company's Board of Directors
adopted an Outside Directors' Warrant Plan (the "Plan").
 
     In December 1994, three new outside directors of the Company were awarded a
total of 450,000 warrants. Each director received 150,000 warrants and each
warrant entitles the director to purchase one share of the Company's common
stock on or prior to December 15, 1999 per the following terms:

</TABLE>
 
     Concurrent with the above initial grant, a fourth outside director of the
Company was awarded 126,000 warrants. The terms of this grant were exactly as
those described above except the number of warrants at the $1.50 exercise price
was set at 26,000 instead of 50,000.
 
     During 1997, outside directors paid the Company approximately $900,000 to
exercise 358,660 warrants. As of December 31, 1997, 217,340 warrants are
exercisable by the Company's outside directors under the Plan.
 
     In December 1994, the Company's Board of Directors awarded Steven A. Odom,
who joined the Board in October 1994 and became Chairman in November 1994, an
initial grant of 450,000 warrants under the Plan. Each warrant entitles Mr. Odom
to purchase one share of the Company's common stock on or prior to December 15,
1999 per the following terms:

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     In August 1997, Mr. Odom paid the Company $225,000 to exercise 150,000
warrants at $1.50. As of December 31, 1997, 300,000 warrants are exercisable by
Mr. Odom under the Plan.
 
     In December 1994, the Board also adopted the Directors Warrant Incentive
Plan, pursuant to which the Board, beginning in 1997, may grant to each director
on an annual basis warrants to purchase up to 50,000 shares of Company common
stock at an exercise price per share equal to no less than 110% of the fair
market value of the common stock at the date of grant. Warrants may only be
issued under this plan if the Company's common stock has appreciated by a
compounded annual average rate of in excess of 35% for the four years preceding
the year of grant. In March 1997, the four outside directors of the Company were
each granted warrants to purchase 50,000 shares of Company common stock at $9.21
per share. These warrants became fully vested on December 31, 1997.
 
     The vesting of all warrants awarded pursuant to the plans above will be
subject to the director to whom such warrants have been granted attending at
least 75% of the meetings of the Board of Directors for the year in which such
warrants are scheduled to vest. Notwithstanding this limitation, the warrants to
be awarded pursuant to the plans will become immediately exercisable (i) if the
Company is to be consolidated with or acquired by another entity in a merger,
(ii) upon the sale of substantially all of the Company's assets or the sale of
at least 90% of the outstanding common stock of the Company to a third party,
(iii) upon the merger or consolidation of the Company with or into any other
corporation or the merger or consolidation of any corporation with or into the
Company (in which consolidation or merger the shareholders of the Company
receive distributions of cash or securities as a result thereof), or (iv) upon
the liquidation or dissolution of the Company.
 
STOCK OPTION PLANS
 
     In 1991, the Company's stockholders adopted the 1991 Stock Option Plan (the
"1991 Plan"). The 1991 Plan, as amended, provided for the granting of up to
3,500,000 options. As of December 31, 1997, no options were available for future
grant under the 1991 Plan.
 
     In December 1997, the Company's Board of Directors authorized the adoption
of the 1998 Incentive Compensation Plan (the "1998 Plan"). The 1998 Plan, which
is subject to shareholder approval, provides for the granting of up to 5,000,000
options. As of December 31, 1997, there were 4,025,000 options available for
future grant under the 1998 Plan.
 
     These plans allow the Board of Directors to grant non-qualified and
incentive stock options to purchase the Company's common stock at an exercise
price not less than fair market value as of the grant date. Options issued under
these plans typically vest over a four year period. Options awarded under the
1991 Plan and the 1998 Plan are subject to the same vesting acceleration
provisions described above under the Director warrant plans.

     In December 1995, the Company offered a voluntary salary reduction program
for 1996 that resulted in the grant of 424,627 non-qualified stock options at
the then current market price of $7.00 per share. Salaried employees voluntarily
agreed to reduce their salaries by $849,254, i.e. $2 in exchange for each stock
option granted. The options vested based upon the attainment of specific
financial and operational objectives during the year. As of December 31, 1996,
these options had become fully vested.
 
     In December 1996, the Company offered a similar voluntary salary reduction
program for 1997 that resulted in the grant of 413,019 non-qualified options at
the then current market price of $8.00 per share. Salaried employees voluntarily
agreed to reduce their salaries by $826,038, i.e. $2 in exchange of each stock
option granted. The options vested based upon the Company achieving key
operational objectives during the year including 25% internal sales growth,
improved inventory turnover and specific enhancements to the Company's quality
and information systems designed to facilitate growth. As of December 31, 1997,
these options had become fully vested.
 
     An additional element of the 1996 and 1997 voluntary salary reduction
programs provided for the potential repayment of salaries if certain pre-tax
income amounts are realized by the Company. Full repayment was earned and
recorded to expense in 1996 and a 30% partial repayment was earned and recorded
to expense in 1997.
 
     In August 1995, the Company granted its new President and Chief Operating
Officer 400,000 options at $3.78 per share, the market price of the Company's
common stock on the date his offer of employment was accepted. These options
vest 25% on each of the first four anniversaries from the initial date of
employment.

     In December 1995, the Company granted its Chairman and Chief Executive
Officer and its Vice President and Chief Financial Officer 200,000 and 50,000
options, respectively, at the then market price of $7.00 per share. The 200,000
options vested 50% on the first two anniversaries from the date of grant. The
50,000 options vested 25% immediately and the remaining 25% on each of the next
three anniversaries from the date of grant.
 
     In December 1997, the Company made an initial grant of 975,000 options
under the 1998 Plan to its Chairman and Chief Executive Officer (400,000
options), President and Chief Operating Officer (300,000 options), Executive
Vice President and Chief Financial Officer (200,000 options) and Executive Vice
President of Business Development (25,000 options). These options, which are
subject to stockholder approval, vest 25% on each of the first four
anniversaries from the date of grant and are exercisable at $19.00 per share,
the market price at the date of grant. The date the stockholders approve the
1998 Plan will become the measurement date for purposes of computing
compensation expense, if any. If the stock price as of the measurement date
exceeds $19.00, then the total compensation impact will be the difference
between stock price at the measurement date and $19.00. The Company will record
that expense ratably over a period of four years.
 
PRO FORMA RESULTS OF OPERATIONS
 
     The Company has elected to follow APB Opinion No. 25, "Accounting for Stock
Issued to Employees," and related Interpretations in accounting for its employee
stock options. Therefore, no compensation cost has been recognized related to
stock options. If the company had elected to account for its stock options under
the fair value method of SFAS No. 123, "Accounting for Stock-Based
Compensation", the Company's net income and net income per common share would
have been reduced to the pro forma amounts indicated below:

     The Black-Scholes option valuation model was developed for use in
estimating the fair value of traded options that have no vesting restrictions
and are fully transferable. In addition, option valuation models require the
input of highly subjective assumptions, including the expected stock price
volatility. Since the Company's employee stock options have characteristics
significantly different from those of traded options and changes in the
subjective input assumptions can materially affect the fair value estimate, the
existing models, in management's opinion, do not necessarily provide a reliable
single measure of the fair value of the Company's employee stock options.

NOTE J:  RETIREMENT SAVINGS PLAN
 
     The Company has a retirement savings 401(k) plan that covers substantially
all employees. The plan provides for the employees to voluntarily contribute a
portion of their compensation on a tax deferred basis and allows for the Company
to make discretionary matching contributions as determined by the Board of
Directors. For the years ended December 31, 1997, 1996 and 1995, the Company
contributed approximately $109,000, $42,000 and $19,000, respectively, in the
form of Company common stock to the Plan. In 1997, Company contributions were
based on a 50% match to employee contributions, up to the first six percent
contributed.
 
NOTE K:  INCOME TAXES
 
     The Company uses the asset and liability approach for financial accounting
and reporting for income taxes. Certain expenses are reported for financial
accounting purposes in different periods than for income tax purposes. These
temporary differences arise primarily from depreciation, bad debt reserves,
inventory valuation and various reserves.
 
     The provision for income taxes for the years ended December 31, 1997 and
1996 was computed in accordance with SFAS No. 109, "Accounting for Income Taxes"
and consists of the following:

     As of December 31, 1997, the Company has capital loss carryforwards of
approximately $1.2 million expiring in 1998.
 
     As a result of the exercises of non-qualified stock options and warrants by
the Company's directors and employees during 1997, the Company has realized a
federal income tax benefit of approximately $6.7 million. This tax benefit has
been accounted for as a decrease in current income taxes payable and an increase
in capital in excess of par value.

     As a result of the significant decline in analog circuit board repair
revenues experienced by the Company in recent years, the shift in strategic
focus to new digital repair services and programs offered by the Company in
1995, the acquisition of AIT and other market considerations, the Company
elected to consolidate certain operations and significantly write-down the net
book value of certain assets related to repair operations. These assets
primarily represent test equipment, tooling, dies and diagnostic programs for
the repair of analog telecommunications equipment. All of these assets were
capitalized in 1988 to 1990 in connection with acquisitions made by the Company.

NOTE M:  RELATED PARTY TRANSACTIONS
 
     In October 1997, John D. Phillips, a director of the Company, entered into
a series of agreements whereby, among other things, he became the new Chairman
and Chief Executive Officer of Cherry Communications Incorporated (d/b/a
Resurgens Communications Group) ("Resurgens"), a facilities-based provider of
international network access commonly referred to as a carriers' carrier.
Resurgens was shortly thereafter placed into bankruptcy under Chapter 11 of the
United States Bankruptcy Code. WorldCom, Inc. ("WorldCom"), a major customer and
vendor of Resurgens, has subsequently agreed to provide Resurgens up to $28
million in financing in the form of a debtor in possession facility and other
credits.
 
     During the fourth quarter of 1997, the Company shipped switching equipment
to Resurgens. The cost of this equipment was approximately $3.8 million. On
February 12, 1998, the Company executed a letter of intent to acquire Resurgens.
The equipment shipped to Resurgens is included in the Company's inventory at
December 31, 1997 (see "Note C").
 
     The Resurgens acquisition is subject to, among other things, the
satisfactory completion by the Company of its due diligence investigation of
Resurgens, the preparation and execution of a definitive merger agreement, the
receipt of the requisite corporate and regulatory approvals and the confirmation
of Resurgens' Plan of Reorganization.
 
NOTE N:  SUBSEQUENT EVENTS
 
ATI ACQUISITION
 
     On December 24, 1997, the Company entered into an agreement to acquire
Advanced TechCom, Inc. ("ATI"), a Wilmington, Massachusetts based designer and
manufacturer of digital microwave and millimeterwave radio systems for short and
long haul voice, data and/or video applications. On January 29, 1998, the
transaction was completed in its final form whereby ATI was merged with and into
CIS, a wholly-owned subsidiary of the Company (the "ATI Merger"). In connection
with the ATI Merger, the stockholders of ATI received approximately $300,000 in
cash and 418,054 restricted shares of the Company's common stock. These shares
had an initial fair value of approximately $8.0 million.
 
     In addition to the 418,054 shares noted above, the stockholders of ATI were
issued 209,050 restricted shares of the Company's common stock. These shares
were immediately placed into escrow and will be released to the stockholders of
ATI contingent upon the realization of predefined levels of pre-tax net income
from ATI's operations during calendar years 1998 and 1999.
 
     In December 1997, the Company loaned ATI approximately $4.5 million. The
note receivable from ATI is included in Other assets on the Company's balance
sheet at December 31, 1997.
 
NACT ACQUISITION
 
     In the fourth quarter of 1997, the Company began a three phase acquisition
of NACT. NACT, based in Provo Utah, is a leading single-source provider of
advanced telecommunications switching platforms with integrated telephony
software applications and network telemanagement capabilities.
 
     During November and December 1997, the Company purchased 355,000 shares of
NACT common stock in the open market for approximately $5.0 million (see "Note
A").
 
     On December 31, 1997, the Company entered into a stock purchase agreement
with GST and GST USA to acquire 5,113,712 shares of NACT common stock owned by
GST USA, representing approximately 63% of the outstanding shares of NACT (the
"Acquisition"). On February 27, 1998, the Acquisition was completed with GST USA
receiving $59.7 million in cash and 1,429,907 restricted shares of the Company's
common stock. These shares had an initial fair value of approximately $23.0
million.
 
     On February 24, 1998 the Company entered into a merger agreement with NACT
pursuant to which the Company agreed to acquire all of the shares of NACT common
stock not already owned by the Company or

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
GST USA. Pursuant to the terms of the merger agreement, each share of NACT
common stock will be converted into shares of Company common stock having a
value of $17.50 per share based on the average of the daily closing price of
Company common stock on the Nasdaq National Market for a pre-defined period
prior to the closing (the "Closing Price"), provided that if the Closing Price
is more than $25.52, then each share of NACT common stock will be converted into
0.6857 shares of Company common stock. If the Closing Price is less than $20.88,
then the Company may elect to terminate the agreement. The merger is subject to,
among other things, the approval of the NACT stockholders and the satisfaction
of certain other customary conditions.
 
     On August 24, 1996, Aerotel, Ltd. and Aerotel U.S.A. Inc. (collectively,
"Aerotel") commenced an action against NACT and a customer of NACT in the United
States District Court, Southern District of New York, alleging that telephone
systems manufactured and sold by NACT incorporating prepaid debit card features
infringe upon Aerotel's patent which was issued in November 1987 (the "Aerotel
Patent"). Aerotel sought injunctive relief, damages in an unspecified amount,
damages of up to three times damages found for willful infringement of the
Aerotel Patent and an order requiring NACT to publish a written apology to
Aerotel. NACT filed an answer and Counterclaim in which it denied infringement
of the Aerotel Patent and sought judgement that the Aerotel patent is invalid
and unenforceable and that Aerotel has misused its patent in violation of
antitrust laws. NACT has denied that it has committed defamation, unfair
competition and tortious interference with prospective business relations. In
August 1997, Aerotel amended its complaint to include as defendants GST, GST
USA, and two former executive officers of NACT. The amended pleadings seek in
excess of $18.7 million in damages and allege that GST and GST USA have
infringed the Aerotel patent, aided and abetted infringement by others,
including NACT, and participated in, and aided and abetted alleged tortious
conduct by NACT. GST, GST USA and the two former executive officers of NACT have
served answers denying all material allegations and intend to defend vigorously.
 
     Under the terms of the Company's stock purchase agreement with GST, the
Company and GST have agreed to share evenly the costs of any judgement against
NACT as a result of the Aerotel litigation, including NACT's legal fees. The
Company believes that NACT has valid defenses to the Aerotel claims. An
unfavorable decision in this action could have a material adverse effect on the
Company's financial position.
 
RESURGENS PENDING ACQUISITION
 
     On February 12, 1998, the Company executed a letter of intent to acquire
Resurgens (see "Note M").
 
PRO FORMA RESULTS OF OPERATIONS
 
     On a pro forma, unaudited basis, as if the acquisitions of ATI and NACT had
occurred as of January 1, 1996, total sales, operating income, net income (loss)
and diluted net income (loss) per common share for the years ended December 31,
1997 and 1996 would have been approximately $136,520,000 and $80,360,000;
$13,608,000 and $13,000; $6,919,000 and $(629,000); and $0.37 and $(0.04),
respectively.
 
     These unaudited pro forma results have been prepared for comparative
purposes only and are not necessarily indicative of the results of operations
which would actually have occurred had the acquisitions been in effect on the
date indicated.

TechCom, Inc. and Subsidiaries (the "Company") as of December 31, 1997, and the
related consolidated statements of operations, stockholder's equity, and cash
flows for the year then ended. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the consolidated financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the consolidated 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 audit provides 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 Advanced
TechCom, Inc. and Subsidiaries as of December 31, 1997 and the results of their
operations and their cash flows for the year then ended in conformity with
generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                          YEAR ENDED DECEMBER 31, 1997
 
NOTE A -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
BUSINESS
 
     Advanced TechCom, Inc. and Subsidiaries (the "Company") designs, develops
and manufactures a series of high-performance digital microwave/millimeter wave
radio equipment, operating in frequencies of 1.5 GHZ to 38 GHZ utilized in the
telecommunications industry.
 
PRINCIPLES OF CONSOLIDATION
 
     The accompanying consolidated financial statements include the accounts of
the Company and its wholly owned foreign sales corporation, Advanced TechCom
(Barbados), Inc. They also include the accounts of Advanced TechCom de Mexico,
S.A. de C.V. which is owned equally by Advanced TechCom, Inc. and Advanced
TechCom (Barbados), Inc.
 
REVENUE RECOGNITION
 
     The Company recognizes revenue from the sales of products when the products
are shipped. Sales to overseas customers generally require letters of credit
before the products are shipped.
 
ALLOWANCE FOR DOUBTFUL ACCOUNTS
 
     An allowance for doubtful accounts is provided when accounts are considered
uncollectible.
 
INVENTORY
 
     Inventory is stated at the lower of cost (first-in, first-out method) or
market.
 
PROPERTY AND EQUIPMENT
 
     Depreciation is computed using the straight-line method over the estimated
useful lives of the assets. Estimated useful lives of assets are as follows:
 
<TABLE>
<S>                                        <C>
Machinery, equipment and other...........  3-7 years
Furniture and fixtures...................  3-7 years
Leasehold improvements...................  Shorter of lease term or useful life
</TABLE>
 
FINANCIAL INSTRUMENTS
 
     The carrying values of cash, accounts receivable, accounts payable and
borrowings under the Company's various debt instruments approximate fair value
due to the short-term nature of these instruments.
 
INCOME TAXES
 
     The Company is taxed as a C Corporation. Deferred tax assets and
liabilities are recognized for the expected future tax consequences of events
that have been included in the financial statements or tax returns. Deferred
income taxes are determined based on the difference between the financial
statement and tax basis of assets and liabilities using enacted tax rates in
effect for the year in which the differences are expected to reverse. Valuation
allowances are established when necessary to reduce deferred tax assets to the
amounts expected to be realized.
 
RESEARCH AND DEVELOPMENT
 
     Research and development costs are expensed when incurred.
 
WARRANTY RESERVE
 
     The Company sells the majority of its products with a two-year repair or
replacement warranty. The accompanying consolidated financial statements include
an accrual of $586,339 for estimated warranty claims based on the Company's
actual claims and anticipated future claims.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
EMPLOYEE STOCK-BASED COMPENSATION
 
     The Company used the intrinsic value-based method of Accounting Principles
Board Opinion ("APB") No. 25 as allowed under Statement of Financial Accounting
Standards ("SFAS") No. 123, "Accounting for Stock-Based Compensation," to
account for all of its employee stock-based compensation plans.
 
CUSTOMERS AND CONCENTRATION OF CREDIT RISK
 
     The Company's products are sold both directly to customers and through
distributors. The Company's customers consist of domestic and international
wireless and cellular companies, telephone companies, utilities and government
and educational institutions.
 
     Approximately 93% of the Company's net sales are derived from international
customers. A major international systems integrator, who resells worldwide,
accounted for approximately 18% of the Company's 1997 net sales and
approximately 12% of the accounts receivable balance at December 31, 1997. A
second customer accounted for approximately 16% of the Company's 1997 net sales
and approximately 10% of the accounts receivable balance at December 31, 1997.
 
USE OF ESTIMATES
 
     The preparation of the Company's consolidated financial statements in
conformity with generally accepted accounting principles requires management to
make estimates and assumptions that affect the reported amounts and disclosures
of certain assets and liabilities at the balance sheet date. Actual results may
differ from such estimates.
 
NOTE B -- FUNDING OF OPERATIONS
 
     As shown in the consolidated financial statements for the year ended
December 31, 1997, the Company incurred a net loss of $10,383,249 and had
negative cash flow from operations of $5,108,715. The Company's 1997 loss and
working capital needs were principally funded by proceeds from a private
placement equity offering, issuance of short-term debt and borrowings under a
line of credit.
 
     On December 24, 1997, the Company entered into an agreement and plan of
merger with World Access, Inc. and its wholly owned Subsidiary, Cellular
Infrastructure Supply, Inc. (which is a more fully described below). This merger
was completed in January, 1998. Subsequent to the merger, management made
significant revisions to its plan of operations including personnel cut backs
and expenditure reductions.
 
NOTE C -- ACCOUNTS RECEIVABLE
 
     At December 31, 1997, the Company evaluated its accounts receivable and
determined that $413,092 of accounts receivable may be uncollectible. Such
amount has been established as an allowance for doubtful accounts at December
31, 1997.
 
     Accounts receivable is comprised of the following at December 31, 1997:

     The Company had a revolving bank line of credit up to a maximum of
$2,500,000 which was due on demand and had interest at the bank's prime rate
plus 1/2%. The line was collateralized by substantially all of the Company's
assets. This line of credit required, among other things, minimum levels of
consolidated tangible net worth, maintenance of certain financial ratios and a
minimum base of inventory and accounts receivable. The Company was out of
compliance with such covenants.
 
     In December 1997, World Access, Inc., assumed the bank's position under
such agreement via assignment by the bank.
 
     World Access, Inc. subsequently increased the line of credit to $5,000,000
and waived compliance with certain covenants.
 
     World Access, Inc. also repaid certain notes payable by the Company to the
bank in the amount of $117,344 which was applied against the line of credit
extended to the Company.
 
     Subsequent to December 31, 1997, all of the notes payable except the line
of credit, the premium finance agreement and the capital lease obligations were
refinanced by the Company by requesting funds from World Access, Inc. for such
purpose. World Access, Inc. formally merged the Company into its wholly owned
subsidiary in 1998. As such debts were in substance, refinanced in 1998, they
are included in current liabilities.
 
NOTE G -- INCOME TAXES
 
     Deferred income taxes are provided for temporary differences in the
recognition of certain income and expense items for financial reporting and
income tax purposes. Such temporary differences relate primarily to depreciation
methods, inventory allowances, the recognition of certain liabilities for
financial statement purposes that can not be recognized for tax purposes until
later periods and the difference in the recognition of the tax effects of
operating losses for financial reporting and income tax purposes.
 
     As of December 31, 1997, the Company had a net deferred tax asset of
approximately $7,437,000 which consisted of the following:

* Series A preferred stock
 
     The preferred stock has voting rights similar to common stock and equal to
the number of whole shares of common into which the preferred is convertible.
The preferred stock also has preference on liquidation over common stock and on
the payment of dividends. The Series A preferred stock shall be convertible,
without the payment of any additional consideration by the holder, at any time
at the option of the holder, at a conversion rate, subject to adjustment, of one
share of common for each share of preferred.
 
     Each share of Series A preferred stock shall automatically be converted
into common stock at the then effective applicable conversion rate upon the
closing of a public offering with gross proceeds of not less than $15 million or
upon the affirmative vote of the majority of the preferred stockholders.
 
NOTE I -- OPTIONS
 
     During 1995, the Company adopted the 1995 Stock Option Plan (the "1995
Plan"). The 1995 Plan initially permitted the grant of options to purchase up to
1,200,000 shares of the Company's common stock at a price at least equal to the
fair market value of the stock, determined by the Board, on the date of grant
for incentive stock options and at prices determined by the Board in its sole
discretion for nonqualified options. On September 6, 1996, the Board and
stockholders approved an increase in the shares available for grants to
1,650,000.
 
     During the fourth quarter of 1996, the Company repriced all options to
reflect the then fair market value of the Company's common stock. The repricing
provided each option holder the right to exchange their existing stock options
for new incentive stock options (the "new options") to purchase an identical
number of shares of common stock at an exercise price of $.26 per share. The new
options vest according to the original vesting schedule but with a six-month
delay, or in 16 equal quarterly installments beginning three months before the
original vesting date. The options are exercisable for 10 years from the
original date of grant.
 
     At December 31, 1997, there were 824,250 options available for grant under
the 1995 Plan.
 
     Stock Exchanged for Services -- During 1997, the Company issued 200,000
shares of preferred stock in exchange for services by a Director of the Company.
The value of the services provided amounting to $200,000 for 1997 has been
charged to operations.
 
     A summary of all stock option activity for the year ended December 31, 1997
is as follows:

PRO FORMA DISCLOSURES
 
     As described in Note 1, the Company applies the intrinsic value method of
APB No. 25 and related Interpretations in accounting for its stock option plan.
Accordingly, no compensation cost has been recognized for its stock option plan.
Had compensation cost been determined based on the fair value at the grant dates
for awards under the plan consistent with the method of SFAS No. 123, the
Company's net loss for the year ended December 31, 1997 would have been
approximately $10,449,961.
 
     For purposes of pro forma disclosures, the fair value of the options
granted under the Company's stock options plans during 1997 was estimated on the
date of grant using the Black-Scholes option pricing mode. Key assumptions used
to apply this pricing model are as follows:
 
<TABLE>

Risk-free interest rate....................................            6.50%
Expected life of option grants.............................          5 years
</TABLE>
 
     The pro-forma disclosures, as required by SFAS No. 123, only include the
effects of options granted in 1997.
 
NOTE J -- EMPLOYEE BENEFIT PLAN
 
     In 1994, the Company established a 401(k) retirement plan for substantially
all employees. Employees eligible to participate in the plan must be age 21. The
Company does not contribute to the plan.
 
NOTE K -- LEASES
 
     The Company leases its present facilities in Wilmington, Massachusetts,
under a five-year lease expiring in November 2000. Future minimum lease payments
under noncancelable operating leases with initial or remaining terms of one year
or more consist of the following at December 31, 1997.

                          INDEPENDENT AUDITORS' REPORT
 
To the Stockholders and Board of Directors of Advanced TechCom, Inc.
  Wilmington, Massachusetts
 
     We have audited the accompanying consolidated balance sheets of Advanced
TechCom, Inc. and Subsidiary (the "Company") as of December 31, 1996 and 1995,
and the related consolidated statements of operations, stockholders' equity, and
cash flows for the years then ended. 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, such consolidated financial statements present fairly, in
all material respects, the financial position of Advanced TechCom, Inc. and
Subsidiary as of December 31, 1996 and 1995, and the results of their operations
and their cash flows for the years then ended in conformity with generally
accepted accounting principles.
 
     As discussed in Note 2 to the consolidated financial statements, subsequent
to year end the Company entered into an agreement to subcontract certain of its
manufacturing, raised additional equity, and received a commitment for
additional financing.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                     YEARS ENDED DECEMBER 31, 1996 AND 1995
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Business.  Advanced TechCom, Inc. and Subsidiary (the "Company") designs,
develops and manufactures a series of high-performance digital
microwave/millimeter wave radio equipment, operating in frequencies of 1.5 GHZ
to 38 GHZ utilized in the telecommunications industry.
 
     Principles of Consolidation.  The accompanying consolidated financial
statements include the accounts of the Company and its wholly owned foreign
sales corporation, Advanced TechCom (Barbados), Inc. All material intercompany
transactions and balances have been eliminated.
 
     Stock Split.  In November 1996, the Board of Directors declared a
three-for-one split of the Company's common and preferred stock effected in the
form of stock dividends. Shares will be distributed to all stockholders of
record. All share and per share data have been adjusted to reflect the split.
 
     Revenue Recognition.  The Company recognizes revenue from the sales of
products when the products are shipped. Sales to overseas customers generally
require letters of credit before the products are shipped.
 
     Allowance for Doubtful Accounts.  An allowance for doubtful accounts is
provided when accounts are considered uncollectible. No such allowances were
considered necessary at December 31, 1996 and 1995.
 
     Inventory.  Inventory is stated at the lower of cost (first-in, first-out
method) or market.
 
     Property and Equipment.  Depreciation is computed using straight-line and
accelerated methods over the estimated useful lives of the assets. Estimated
useful lives of assets are as follows:
 
<TABLE>

Machinery and equipment and other.......................              3-5 years
Furniture and fixtures..................................              3-7 years
Leasehold improvements..................................  Shorter of lease term
                                                                 or useful life
</TABLE>
 
     Financial Instruments.  The carrying values of cash, accounts receivable,
accounts payable, borrowings under the Company's credit line and debt
approximate fair value due to the short-term nature of these instruments.
 
     Income Taxes.  The Company is taxed as a C Corporation. Deferred tax assets
and liabilities are recognized for the expected future tax consequences of
events that have been included in the financial statements or tax returns.
Deferred income taxes are determined based on the difference between the
financial statement and tax basis of assets and liabilities using enacted tax
rates in effect for the year in which the differences are expected to reverse.
Valuation allowances are established when necessary to reduce deferred tax
assets to the amounts expected to be realized.
 
     Research and Development.  Research and development costs are expensed when
incurred.
 
     Warranty Reserve.  The Company sells the majority of its products with a
two-year repair or replacement warranty. The accompanying consolidated financial
statements for 1996 and 1995 include an accrual of approximately $403,000 and
$150,000, respectively, for estimated warranty claims based on the Company's
experience of actual claims and anticipated future claims.
 
     Employee Stock.  Based Compensation -- The Company uses the intrinsic
value-based method of Accounting Principles Board Opinion ("APB") No. 25. as
allowed under Statement of Financial Accounting Standards ("SFAS") No. 123
"Accounting for Stock-Based Compensation," to account for all of its employee
stock-based compensation plans.
 
     Customers and Concentration of Credit Risk.  The Company's products are
sold both directly to customers and through distributors. The Company's
customers consist of domestic and international wireless and cellular companies,
telephone companies, utilities and government and educational institutions.
Approximately 93% of the Company's net sales are derived from international
customers. A major international systems integrator, who resells worldwide,
accounted for approximately 20% of the Company's 1996 net sales

and approximately 54% of the accounts receivable balance at December 31, 1996. A
second customer accounted for approximately 14% of the accounts receivable
balance at December 31, 1996.
 
     Use of Estimates.  The preparation of the Company's consolidated financial
statements in conformity with generally accepted accounting principles requires
management to make estimates and assumptions that affect the reported amounts
and disclosure of certain assets and liabilities at the balance sheet date.
Actual results may differ from such estimates.
 
     Reclassifications.  Certain amounts in the 1995 financial statements have
been reclassified to conform with the 1996 presentation.
 
     Adoption of New Accounting Pronouncements.  Effective January 1, 1996, the
Company adopted, prospectively, SFAS No. 121, "Accounting for Impairment of
Long-lived Assets and for Long-lived Assets to Be Disposed Of." SFAS No. 121
requires that long-lived assets be reviewed for impairment whenever
circumstances indicate that the carrying value of an asset may not be
recoverable. The adoption of SFAS No. 121 did not have a significant effect on
the Company's consolidated financial position or results of operations for the
year ended December 31, 1996.
 
     Effective January 1, 1996, the Company adopted SFAS No. 123, "Accounting
for Stock-Based Compensation." As permitted by SFAS No. 123 the Company has
continued to account for its stock-based transactions to employees in accordance
with APB No. 25, "Accounting for Stock Issued to Employees." As required by SFAS
No. 123 for stock option grants to nonemployees, the Company follows the
provisions of SFAS No. 123, calculates compensation expense using a fair value
based method and amortizes compensation expense over the vesting period. During
the year ended December 31, 1996, the Company did not grant any options to
purchase shares of common stock to nonemployees.
 
2. FUNDING OF OPERATIONS
 
     As shown in the consolidated financial statements, for the year ended
December 31, 1996, the Company incurred a net loss of $6,157,751 and had
negative cash flow from operations of $4,019,993. The Company's 1996 loss and
working capital needs were principally funded by proceeds from various private
placement equity offerings completed throughout the year.
 
     Since December 31, 1996, the Company has continued to incur losses.
However, it has negotiated a line of credit for borrowings of up to $2.5 million
and raised approximately $3.0 million through the issuance of preferred stock.
Moreover, the Company has entered into a joint venture agreement to subcontract
the manufacturing of certain of its products and, upon the successful
refinancing of the Company's existing bank line of credit or financing with a
new bank, the agreement will also provide up to $2.0 million of additional
financing. On October 15, 1997, the Company received a commitment letter for
bank financing of $750,000. The Company is also now selling its compact product
line in the 38 GHZ and 23 GHZ frequencies, thus improving its existing product
line offerings and plans to raise additional equity financing in 1997.
Management believes these factors will provide sufficient working capital for
the remainder of 1997 and into 1998.

     The Company had a revolving bank line-of-credit agreement which expired in
May 1996. Since the expiration of the agreement, borrowings under the line were
based on eligible accounts receivable and inventory up to a maximum of
$1,245,000. At December 31, 1996, the Company had outstanding bank letters of
credit totaling $172,657, of which $32,657 reduces borrowing availability under
the line of credit. The line is payable on demand and bears interest at the
bank's prime rate plus  1/2% (8.75% at December 31, 1996). The line is
collateralized by substantially all of the Company's assets and is personally
guaranteed by the principal stockholder of the Company. The agreement contains
certain covenants which, among other things, require minimum levels of
consolidated tangible net worth, the maintenance of certain financial ratios,
and a minimum collateral base of inventory and accounts receivable. At December
31, 1996, the Company was not in compliance with certain provisions of the loan
agreement related to the minimum debt coverage ratio requirement.
 
     On March 13, 1997, the Company's bank line-of-credit agreement was amended.
The amended agreement provides for available borrowings under the line based on
eligible accounts receivable up to a maximum of $2,500,000, reduced by
outstanding letters of credit issued by the Company. The line is payable on
demand and bears interest at the bank's prime lending rate plus  1/2%. The line
is collateralized by substantially all of the Company's assets and is personally
guaranteed by the principal stockholder of the Company. The agreement contains
certain covenants which, among other things, require minimum levels of

consolidated tangible net worth, the maintenance of certain financial ratios,
and a minimum collateral base of inventory and accounts receivable. As of
October 15, 1997, approximately $2,200,000 was outstanding under the line and
the Company was in default on certain covenant requirements. The Company is
currently discussing refinancing of the line (see Note 2).

     Deferred income taxes arise from temporary differences resulting from
income and expense items reported for financial accounting and tax purposes in
different periods and future tax benefits of federal and state tax credits. At
December 31, 1995, deferred tax assets totaling $509,537, with a related
valuation

allowance of $405,081, or net deferred tax assets of $104,456, were recorded
based upon management's assessment at that time that taxable income would more
likely than not be sufficient to utilize fully the net deferred tax asset. At
December 31, 1996, based on operating results and management's reassessment of
future taxable income, the Company established a valuation allowance to reduce
the carrying value of net deferred tax assets to zero.
 
     At December 31, 1996, the Company had available unused federal research and
development credits of approximately $202,000 which expire in the years 2010 and
2011, state research and development credits of approximately $388,000, of which
approximately $7,300 are unlimited and the remainder expire at various dates
beginning in 2006 through 2011 and an investment tax credit of $21,837. Net
operating loss carryforwards totaled approximately $5,080,000 at December 31,
1996.
 
8. STOCKHOLDERS' EQUITY
 
     On November 7, 1996, the Company amended the Company's Certificate of
Incorporation to increase the authorized preferred stock to 20,000,000 shares
with par value of $.10 per share; 15,000,000 shares designated as Series A
convertible preferred stock ("Series A preferred stock") and 5,000,000 shares as
undesignated preferred stock (see "Stock Split" in Note 1).
 
     The preferred stock has voting rights similar to common stock and equal to
the number of whole shares of common into which the preferred is convertible.
The preferred stock also has preference on liquidation over common stock and on
the payment of dividends. The Series A preferred stock shall be convertible,
without the payment of any additional consideration by the holder, at any time
at the option of the holder, at a conversion rate, subject to adjustment, of one
share of common for each share of preferred. Each share of Series A preferred
stock shall automatically be converted into common stock at the then effective
applicable conversion rate upon the closing of a public offering with gross
proceeds of not less than $15 million or upon the affirmative vote of the
majority of the preferred stockholders.
 
     Concurrent with the increase in the number of authorized shares of
preferred stock, common stockholders were granted the option of converting their
shares into Series A preferred stock on a one-for-one basis.
 
     In addition, additional shares of Series A convertible preferred stock
totaling 965,430 were issued for no additional consideration to those persons
who purchased common stock in April and May 1996 at a price of $20 per share in
order that their purchase price, after taking into account the stock split, be
adjusted to $3 1/3 per share.
 
9. STOCK PLANS
 
     Performance Share Plan.  The Company had a performance share plan which was
intended as an incentive to certain key employees and directors who contribute
to the success of the Company's business. Under the terms of the plan,
performance shares were granted to individuals at the discretion of the
Company's Board of Directors (the "Board"), subject to various vesting
schedules. Performance shares exercised during 1995 totaled 6,980. Shares
forfeited under the plan totaled 17,809 for 1995.
 
     In August 1995, the Board voted to terminate the performance share plan and
authorized the Company's president, in consultation with the Compensation
Committee, to offer stock options in exchange for performance shares held by the
holders thereof.
 
     Stock Options.  During 1995, the Company adopted the 1995 Stock Option Plan
(the "1995 Plan"). The 1995 Plan initially permitted the grant of options to
purchase up to 1,200,000 shares of the Company's common stock at a price at
least equal to the fair market value of the stock, determined by the Board, on
the date of grant for incentive stock options and at prices determined by the
Board in its sole discretion for nonqualified options. On September 6, 1996, the
Board and stockholders approved an increase in the shares available for grants
to 1,650,000.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     During the fourth quarter of 1996, the Company repriced all options to
reflect the then fair market value of the Company's common stock. The repricing
provided each option holder the right to exchange their existing stock options
for new incentive stock options (the "new options") to purchase an identical
number of shares of common stock at an exercise price of $.26 per share. The new
options vest according to the original vesting schedule but with a six-month
delay, or in 16 equal quarterly installments beginning three months before the
original vesting date. The options are exercisable for 10 years from the
original date of grant.
 
     At December 31, 1996, there were 828,137 options available for grant under
the 1995 Plan. Prior to the adoption of the 1995 Plan, the Company issued stock
options to certain individuals which were exercisable on varying dates at prices
ranging from $.67 to $2.57 per share.
 
     Stock Exchanged for Services.  During 1995, the Company issued 47,019
shares of common stock in exchange for current and future services. Of the
47,019 shares issued, 36,000 were issued to a director for services to be
provided through 1997. The right to the 36,000 shares is subject to a two-year
vesting schedule through 1997. The value of the services provided amounting to
$15,000 and $36,000 for 1996 and 1995, respectively, has been charged to
operations. During 1996, an additional 73,014 shares of common stock were issued
in exchange for current services. The value of the shares totaling $94,933 was
expensed in 1996.
 
     A summary of all stock option activity for the years ended December 31,
1996 and 1995 is as follows:

     Pro Forma Disclosures.  As described in Note 1, the Company applies the
intrinsic value method of APB No. 25 and related Interpretations in accounting
for its stock option plans. Accordingly, no compensation cost has been
recognized for its stock option plans. Had compensation cost been determined
based on the fair value at the grant dates for awards under those plans
consistent with the method of SFAS No. 123, the Company's net loss for the years
ended December 31, 1996 and 1995 would have been $6,260,157 and $25,215,
respectively.
 
     For purposes of the pro forma disclosures, the fair value of the options
granted under the Company's stock option plans during 1996 and 1995 was
estimated on the date of grant using the Black-Scholes option pricing model. Key
assumptions used to apply this pricing model are as follows:

                     ADVANCED TECHCOM, INC. AND SUBSIDIARY
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     Interest expense on the note payable to stockholder (see Note 5) was $8,112
for the year ended December 31, 1996.
 
13. SUBSEQUENT EVENT
 
     Subsequent to year end, the Company was named as a defendant in a suit
filed by a successor to a former vendor. The vendor claims it is owed $1,000,000
from the Company and has asserted breach of contract and other claims. The
Company's recorded liability at December 31, 1996 was approximately $450,000.
The Company and the vendor have agreed to stay the litigation while they engage
in settlement negotiations. The ultimate outcome of this claim cannot be
predicted, however, management estimates that the Company's possible loss that
may be incurred will not exceed the amounts recorded.
 
14. EVENTS (UNAUDITED) SUBSEQUENT TO THE DATE OF THE INDEPENDENT
    AUDITORS' REPORT
 
     As discussed in notes 2 and 5, as of October 15, 1997 the Company had
approximately $2,200,000 outstanding and was in default on certain covenant
requirements under its bank line of credit. Moreover, the Company was discussing
the refinancing of this line in connection with a joint venture agreement
entered into to subcontract the manufacturing of certain of its products and had
received a commitment letter for bank financing of $750,000. The commitment
letter expired on December 15, 1997 and on December 29, 1997 the Company signed
a definitive agreement to be acquired by World Access, Inc. In connection with
the acquisition the Company also entered into an agreement to terminate the
joint venture agreement referred to above. In December 1997, World Access paid
the Company's outstanding bank debt and began funding its operations. The
acquisition of the Company, by World Access, was consummated on January 29,
1998.

                         NOTES TO FINANCIAL STATEMENTS
 
1. BASIS OF PRESENTATION
 
     The interim financial statements included herein have been prepared by NACT
Telecommunications, Inc. ("NACT" or the "Company") without audit, pursuant to
the rules and regulations of the Securities and Exchange Commission (the "SEC").
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 SEC rules and regulations. These
condensed financial statements should be read in conjunction with the financial
statements and notes thereto included in the Company's September 30, 1997
audited financial statements filed as part of the Company's Annual Report on
Form 10K with the SEC in December 1997. In the opinion of management, the
condensed financial statements included herein reflect all adjustments necessary
to present fairly the financial position of the Company as of June 30, 1998 and
December 31, 1997, and the results of its operations and cash flows for the
three month and six month periods ended June 30, 1998 and 1997. The results of
operations for the interim periods are not necessarily indicative of the results
of operations for the full year.
 
2. EARNINGS PER SHARE
 
     In February 1997, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards No., 128, Earnings per Share (SFAS
128). SFAS 128 became effective for financial statements with interim and annual
periods ending after December 15, 1997. Accordingly, the Company adopted SFAS
128 for the quarter ended December 31, 1997. SFAS 128 establishes a different
method of computing earnings per common share than was previously required under
the provisions of Accounting Principles Board Opinion No. 15. SFAS 128 requires
the presentation of basic and diluted earnings per common share. Basic earnings
per common share is the amount of earnings for the period available to each
share of common stock outstanding during the reporting period. Diluted earnings
per common share is the amount of earnings for the period available to each
share of common stock outstanding during the reporting period and to each share
that would have been outstanding assuming the issuance of common shares for all
dilutive potential common shares outstanding during the period. The earnings per
common share as previously reported has been restated for all periods presented
to adopt the provisions of SFAS 128.
 
3. STOCK PLAN
 
     In connection with entering into a stock purchase agreement with the
Company (the "NACT Stock Purchase Agreement"), on January 2, 1998 relating to
the purchase by World Access, Inc. ("WAI") of approximately 63% of Company's
outstanding common stock ("NACT Stock Purchase"), WAI entered into option
exchange agreements (the "Option Exchange Agreements") with the holders of
options to purchase an aggregate of 1,034,032 shares of NACT Common Stock (the
"Exchanged Options") representing approximately 99% of all the then-outstanding
options to acquire NACT Common Stock. Pursuant to the Option Exchange
Agreements, upon consummation of the NACT Stock Purchase, each Exchanged Option
was assumed by WAI and now constitutes an option to acquire, on the same terms
and conditions as were applicable under such Exchanged Option, a number of
shares of WAI Common Stock equal to (i) the product of the number of shares of
NACT Common Stock subject to such Exchanged Option (ii) multiplied by 0.8390
with an exercise price per share equal to (i) the aggregate exercise price for
such shares of NACT Common Stock deemed to be purchasable pursuant to such
option; provided, however that none of Exchanged Options will be incentive stock
options under Section 422 of the Code and all such options are now exercisable.
As a result of the consummation of the NACT Stock Purchase Agreement on February
27, 1998, these options will become exercisable for shares of WAI Common Stock
on a one-for-one basis.

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors and Stockholders
NACT Telecommunications, Inc.:
 
     We have audited the accompanying balance sheets of NACT Telecommunications,
Inc. as listed in the accompanying index. In connection with our audits of the
financial statements, we also have audited the financial statement schedule as
listed in the accompanying index. These financial statements and financial
statement schedule are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements and
financial statement schedule 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 financial statements referred to above present fairly,
in all material respects, the financial position of NACT Telecommunications,
Inc. as of September 30, 1997 and 1996, and the results of its operations and
its cash flows for each of the years in the three-year period ended September
30, 1997, in conformity with generally accepted accounting principles. Also in
our opinion, the related financial statement schedule, when considered in
relation to the basic financial statements taken as a whole, presents fairly, in
all material respects, the information set forth therein.

                         NOTES TO FINANCIAL STATEMENTS
                       SEPTEMBER 30, 1997, 1996, AND 1995
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  (a) Organization and Description of Business
 
     NACT Telecommunications, Inc. (the "Company") designs, develops and
manufactures advanced telecommunications switching platforms with integrated
applications software and network telemanagement capabilities. The Company's
customers include long distance carriers, prepaid debit (calling) card and
prepaid cellular network operators, international call back/reorigination
providers and other specialty telecommunications service providers.
 
     From September 1993 through September 30, 1995, GST USA, Inc. ("GST USA")
acquired all of the issued and outstanding common stock of the Company. This
acquisition was accomplished through a series of purchases of newly issued
shares and the shares of principal stockholders of the Company. As a result of
these transactions, the Company became a wholly owned subsidiary of GST USA. GST
USA accounted for the acquisition using the purchase method of accounting. The
excess of the purchase price over the fair value of the assets acquired totaled
$6,912,322 and was assigned by GST USA as product support contracts, software
development costs, and goodwill. These amounts are included in the accompanying
balance sheet as intangible assets.
 
     In February 1997, the Company closed an initial public offering (IPO) of
3,000,000 shares of common stock with 2,000,000 sold by the Company and
1,000,000 sold by GST USA. Upon completion of the offering, GST USA ownership
was reduced to approximately 63 percent of the outstanding common stock of the
Company and, as such, GST USA continues to control the Company. In connection
with the IPO, the Company established a par value of $.01 for common stock,
increased the number of common shares authorized to 25,000,000, and authorized
10,000,000, $.01 par value preferred shares.
 
     On September 30, 1997, GST USA announced that it had retained Hambrecht and
Quist LLC to explore alternatives for monetizing its 63 percent interest in the
Company, including a potential sale of some or all of the Company's capital
stock to one or more strategic investors.
 
  (b) Wasatch International Network Services
 
     The 1995 financial statements include the accounts of the Company and its
wholly-owned subsidiary Wasatch International Network Services, Inc. ("Wins"),
which commenced operations in fiscal 1995 and had total assets, revenues, and
net loss of $316,455, $1,097,950 and $2,361, respectively, as of and for the
year ended September 30, 1995. All significant intercompany transactions and
balances were eliminated in consolidation. On October 1, 1995, the Company
transferred ownership and operations of Wins to GST USA in the form of a
dividend at historical cost. From October 1, 1995 through September 30, 1996,
the Company provided carrier services to GST USA for the Wins operation for
which it received $2,571,731. GST USA began providing its own carrier services
for Wins on October 1, 1996.
 
  (c) Cash and Cash Equivalents
 
     The Company considers all highly liquid financial instruments purchased
with an original maturity to the Company of three months or less to be cash
equivalents. Cash equivalents consist of money market accounts of $8,472,637 at
September 30, 1997 and $125,785 at September 30, 1996.
 
  (d) Inventories
 
     Raw materials are valued at the lower of cost (first-in, first-out) or
market. Work-in-process and finished goods are stated on the basis of
accumulated manufacturing costs, but not in excess of market (net realizable
value). Refurbished inventory is stated at the estimated selling price less
refurbishing costs, selling costs and a normal profit margin. Management
periodically reviews the selling price of the refurbished inventory and records
adjustments to the carrying value, if any, in the period in which they occur.

                    (A MAJORITY OWNED SUBSIDIARY OF GST USA)
 
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     Long-term inventory consists of component parts held in order to provide
support on existing customer equipment beyond one year.
 
  (e) Notes Receivable
 
     Notes receivable are recorded at the principal amount outstanding, net of
an allowance for doubtful notes. The allowance is an amount that management
believes will be adequate to absorb possible losses based on evaluations of
collectibility and prior loss experience. The evaluation takes into
consideration such factors specific problem loans, past payment history, and
current and anticipated economic conditions that may affect the customers'
ability to pay.
 
     While management uses available information to recognize losses on notes,
changing economic conditions and the economic prospects of the borrowers might
necessitate future additions to the allowance.
 
  (f) Impaired Notes
 
     Management, considers a note to be impaired when it is probable that the
Company will be unable to collect all amounts due according to the contractual
terms of the note agreement. When a note is considered to be impaired, the
amount of the impairment is measured based on the present value of expected
future cash flows discounted at the note's effective interest rate. Impairment
losses are included in the allowance for doubtful accounts through a charge to
bad debt expense. Cash receipts on impaired notes receivable are applied to
reduce the principal amount of such notes until the principal has been recovered
and are recognized as interest income thereafter.
 
  (g) Property and Equipment
 
     Property and equipment are stated at cost. Depreciation is computed using
the straight-line method for financial reporting purposes. Depreciation is based
upon the estimated useful lives of individual classes of assets. The estimated
useful lives of the individual classes of assets are as follows:
 
<TABLE>
<S>                                                           <C>
Building....................................................    35 years
Furniture and equipment.....................................  7-10 years
Computer equipment..........................................   3-7 years
Switch and testing equipment................................   3-7 years
</TABLE>
 
  (h) Intangibles
 
     Intangibles include goodwill, software development costs, customer lists,
and product support contracts and are being amortized on a straight-line basis
over the estimated useful lives of the respective assets.
 
  (i) Software Development Costs
 
     Software development costs are capitalized upon the establishment of
technological feasibility of the product. Capitalization is discontinued when
the product is available for general release to customers. The Company
capitalized software development costs of $821,568, $419,154, and $162,025 in
1997, 1996, and 1995, respectively.
 
  (j) Stock-Based Compensation
 
     Effective October 1, 1996, the Company adopted the footnote disclosure
provisions of Statement of Financial Accounting Standards No. 123, Accounting
for Stock-Based Compensation (SFAS 123). SFAS 123 encourages entities to adopt
the fair value based method of accounting for stock options or similar equity
instruments. However, it also allows an entity to continue measuring
compensation cost for stock-based compensation using the intrinsic-value method
of accounting prescribed by Accounting Principles Board

                         NACT TELECOMMUNICATIONS, INC.
                    (A MAJORITY OWNED SUBSIDIARY OF GST USA)
 
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
Opinion No. 25, Accounting for Stock Issued to Employees (APB 25). The Company
has elected to continue to apply the provisions of APB 25 and provide pro forma
footnote disclosures required by SFAS 123.
 
  (k) Revenue Recognition and Deferred Revenue
 
     Revenue from product sales is recognized when the product is shipped and
the Company has no significant performance obligations. Revenue from network
carrier sales is recognized as the related service is provided. Deferred revenue
consists of warranty payments billed or received in advance and deposits related
to future product sales. Warranty payments are amortized over the period of the
warranty agreement which is typically one year.
 
  (l) Income Taxes
 
     Through February 26, 1997, the Company was a member of a controlled group
which elected for federal income tax purposes to file a consolidated tax return
with GST USA. In accordance with the tax sharing arrangement with GST USA, the
Company recorded the estimated income tax expense as if the Company filed a tax
return on a separate company basis using the asset and liability method. GST USA
agreed to make a capital contribution to the Company in an amount that
approximates the Company's current federal income tax expense through February
26, 1997 in lieu of an intercompany payment for such taxes. Pursuant to the tax
sharing arrangement between the Company and GST USA, the adjustment recorded to
reconcile the intercompany and equity accounts with regard to differences
between the estimated tax determined at year-end and the final tax amount are
recognized in income tax expense in the period determined.
 
     The Company uses the asset and liability method of accounting for income
taxes. Under the asset and liability method, deferred tax assets and deferred
liabilities are recognized for the future tax consequences attributable to
differences between the financial statement carrying amounts of existing assets
and liabilities and their respective tax bases and operating loss and tax credit
carryforwards. Deferred tax assets and deferred liabilities are measured using
enacted tax rates expected to apply to taxable income in the years in which
those temporary differences are expected to be recovered or settled.
 
     After the IPO on February 26, 1997, GST USA's ownership was reduced to 63
percent. As a result, the entities no longer meet the affiliated group test
defined in Internal Revenue Code Section 1504(a) and the Company will file
stand-alone returns for periods subsequent to February 26, 1997.
 
  (m) Marketable Investment Securities
 
     The Company classifies all of its marketable investment securities as
available-for-sale which are recorded at fair market value. Unrealized holding
gains and losses are excluded from earnings and are reported, net of tax, as a
separate component of stockholders' equity until realized. A decline in the
market value of any available-for-sale security below cost that is deemed other
than temporary is charged to earnings resulting in the establishment of a new
cost basis for the security. Dividend income is recognized when earned. Realized
gains and losses are included in earnings and are derived using the
specific-identification method for securities sold.
 
  (n) Earnings Per Common and Common Equivalent Share
 
     Earnings per common and common equivalent share are computed based on the
weighted-average number of common shares and as appropriate, dilutive common
stock equivalents outstanding during the period. Stock options are considered to
be common stock equivalents. The number of shares used to compute primary
earnings per common and common equivalent share were 7,350,623, 6,113,712, and
6,113,712, shares in 1997, 1996, and 1995, respectively. The number of shares
used to compute fully-diluted earnings per share reflect additional dilution
related to stock options and warrants using the market price at the end of the
period

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
when higher than the average price for the period. The number of shares used to
compute fully-diluted earnings per share were 7,602,156, 6,113,712, and
6,113,712, shares in 1997, 1996, and 1995, respectively.
 
  (o) Fair Value Disclosure
 
     At September 30, 1997 and 1996, the book value of the Company's financial
instruments approximates fair value.
 
  (p) Use of Estimates
 
     Management of the Company has made a number of estimates and assumptions
relating to the reporting of assets and liabilities and the 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 could differ from these estimates.

(4) NOTES RECEIVABLE
 
     Notes receivable at September 30, 1997 and 1996 include amounts due from
product sales of approximately $4,065,638 and $1,047,500, respectively. Interest
rates on the notes range from 9 percent to 14 percent with lives ranging from
six months to five years.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     The Company's recorded investment in notes receivable for which an
impairment has been recognized was $137,032 and $928,210, and the related
allowance for doubtful accounts was $137,032 and $310,000 at September 30, 1997
and 1996, respectively. The average recorded investment in impaired notes
receivable during 1997 and 1996, was $532,261 and $548,331, respectively. There
was no interest income recognized on impaired notes receivable during 1997 and
1996.
 
     The Company has sold carrier services to Overseas Telecom ("Overseas")
since 1994. Overseas is located in Brazil and provides international call
back/reorigination services to companies and individuals primarily in Brazil and
Eastern Europe. During the year ended September 30, 1996, Overseas became
delinquent on certain of its payments. In fiscal 1997, the Company entered into
a note receivable agreement with Overseas which provided for the repayment of
the noncurrent outstanding amount (approximately $0.93 million) bearing interest
at 12 percent. The note was secured primarily by Overseas' customer lists. In
the fourth quarter of fiscal 1997, the Company exercised its call privileges
under the note and took possession of the underlying collateral -- the customer
lists. There were two separate and distinct customer lists, one from Brazil and
one from Eastern Europe. The customer list related to the Brazilian operations
was sold to Intertoll Communications Network Corp. ("ICN"), an existing customer
of the Company with operations in Argentina and Brazil for $1,000,000 payable in
100 monthly payments of $10,000. The related payments have been discounted at 20
percent with the unpaid amount of approximately $485,000 classified as notes
receivable in the accompanying balance sheet as of September 30, 1997.
 
     The customer list related to the Eastern European operations was recorded
on the Company's books at the lower of fair value or cost. Fair value was
estimated by an independent third party appraiser using generally accepted
valuation standards. Accordingly, a customer list of approximately $964,000 has
been recorded as an intangible asset and will be amortized over a three-year
period.

     On an ongoing basis, management reviews the valuation and amortization of
intangible assets to determine possible impairment by comparing the carrying
value of the asset to its undiscounted estimated future cash flows.
 
     Amortization expense relating to these assets was $1,085,468, $978,813, and
$962,514 for 1997, 1996, and 1995, respectively. Of these amounts, $512,409,
$405,755, and $442,734, for 1997, 1996, and 1995, respectively, was recorded as
a component of cost of goods sold.
 
(7) STOCK OPTIONS
 
     In November 1996, the Company adopted the 1996 Stock Option Plan ("1996
Plan") which was approved by the board of directors and GST USA. The Company has
reserved 1,250,000 shares for issuance under the 1996 Plan, of which options to
purchase 935,250 shares of common stock at an exercise price of $9.35 per share
were granted. All options granted during the year expire on November 25, 2001.
The Company may grant incentive stock options and nonqualified stock options to
employees, officers, directors, independent contractors, and consultants. The
exercise price of options must be greater than or equal to the estimated fair
market value of the stock at the date of grant. The board of directors or the
compensation committee thereof determines which eligible individuals are granted
options, terms of the options, exercise price, number of shares subject to the
option, vesting and exercisability. The 1996 Plan expires on November 25, 2006.

     The Company accounts for these plans under APB 25, under which no
compensation cost has been recognized. Had compensation cost for these plans
been determined consistent with SFAS 123, the Company's net earnings and
earnings per share would have been changed to the following pro forma amount:

</TABLE>
 
     Pro forma net earnings reflects only options granted in fiscal 1997.
Therefore, the effect that calculating compensation cost for stock-based
compensation under SFAS 123 has on the pro forma net earnings as shown above may
not be representative of the effects on reported net earnings for future years.
 
     The fair value of each option grant is estimated on the date of the grant
using the Black-Scholes option pricing model with the following weighted-average
assumptions used for grants in fiscal 1997: risk-free interest rate of 6.0
percent; expected dividend yield of 0 percent; expected life of 3.4 years; and
expected volatility of 82 percent.

     These leases generally require the Company to pay all executory costs such
as maintenance and insurance. Rental expenses for all operating leases for 1997,
1996, and 1995, were $123,462, $100,299, and $116,944, respectively.
 
(10) PROFIT SHARING PLANS
 
     The Company sponsors a defined contribution 401(k) plan (the "Plan") for
employees who have completed one year of service and attained the age of 21.
Participants may defer up to 15 percent of eligible compensation. The Company,
at its discretion, may match 50 percent of participant contributions up to 7.5
percent of participant compensation. Employer contributions made to the Plan
were $88,361, $59,881, and $51,863, for the years ended September 30, 1997,
1996, and 1995, respectively.
 
     Through September 30, 1996, the Company established a discretionary profit
sharing program for full time employees who had completed one full year of
employment. Under the plan, 10 percent of the increase in profits based on the
Company's previous highest retained earnings balance were allocated among
employees determined on length of employment and salary level at the discretion
of the board of directors. Contributions to the program were $132,450 and
$171,483 for the years ended September 30, 1996 and 1995, respectively. The
program was terminated on September 30, 1996.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     The Company's customers consist of business entities geographically
dispersed primarily throughout the United States. However, the Company also
sells products and/or services to customers in the United Kingdom, Bosnia,
Serbia, Bulgaria, Saudi Arabia, and Brazil. The Company maintains a security
interest in the telecommunications systems it sells until the related account
balances are paid in full.
 
     The Company had deposits with financial institutions in excess of the
federally insured amount of $100,000 in the amount of $9,691,380 and $467,737
for the years ended September 30, 1997 and 1996, respectively.
 
     Network carrier sales originating from countries outside the United States
aggregated approximately $3,180,000 and $2,105,000 for the years ended September
30, 1997 and 1996, respectively. These sales are payable in U.S. dollars.
 
(12) COMMITMENTS AND CONTINGENCIES
 
     The Company acted as a guarantor for financing transactions executed under
repurchase agreements with a financial institution for $3,482,182 and $1,035,032
at September 30, 1997 and 1996, respectively. This results from the financial
institution providing lease financing to the Company's customers to enable them
to purchase product from the Company. At September 30, 1997, the Company had
established a reserve of $200,000 for its estimated obligation under the
recourse provisions and maintains a security interest in the equipment financed
under the repurchase agreement. No such reserve was recorded as of September 30,
1996. In addition to other covenants, the repurchase agreement requires the
Company to maintain an unrestricted cash account of $6,000,000. The Company has
also established a $750,000 revolving line of credit with this same financial
institution. No balances were outstanding under this line of credit at September
30, 1997.
 
     On October 1, 1996, the Company entered into employment agreements with
various employees which specify the individual's salary, benefits, and
restrictions. All agreements expire on September 30, 2001.
 
     On August 24, 1995, Aerotel, Ltd. and Aerotel U.S.A., Inc., (collectively,
"Aerotel") filed a patent infringement suit against the Company alleging that
telephone systems manufactured and sold by the Company incorporating prepaid
calling features infringe upon a patent which was issued to Aerotel in November
1987. The complaint further alleges defamation and unfair competition by the
Company and seeks various damages. Aerotel seeks injunctive relief, damages of
$18.7 million for willful infringement of its patent and an order requiring the
Company to publish a written apology to Aerotel. The Company has filed an Answer
and Counterclaim denying patent infringement, defamation or unfair competition
and seeking judgment that the Aerotel patent is invalid and that Aerotel has
misused its patent in violation of antitrust laws. Based on information
currently available, an estimate of potential loss cannot be made. However,
management is of the opinion that there will be no material impact of the
Company's financial position, results of operations or liquidity as a result of
this suit. Accordingly, no provision for loss has been provided in the
accompanying financial statements. An unfavorable decision could have a material
adverse effect on the business, financial condition, and results of operations
of the Company.
 
     In addition to the above, the Company has various legal claims and other
contingent matters, incurred in the normal course of business. Although the
final outcome of such matters cannot be predicted, the Company believes the
ultimate disposition of these matters will not have a material adverse effect on
the Company's financial condition, liquidity, or results of operations.
 
     As of September 30, 1997, the Company had capital expenditure purchase
commitments outstanding of approximately $900,000.
 
(13) RELATED PARTY TRANSACTIONS
 
     In June 1997, and under contract with the Company, GST Realco, Inc. ("GST
Realco"), a subsidiary of GST USA, completed construction of a 40,000 square
foot office building in Provo, Utah. The Company

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
purchased the land and a portion of the building construction from GST Realco
for $563,309 and $1,293,072, respectively, and currently occupies the property
as its corporate and manufacturing facility.
 
     During the year ended September 30, 1996, GST USA borrowed $250,000 from
the Company on short-term notes bearing interest at 11 percent. The note was
repaid by September 30, 1996. The Company recorded interest income of $2,602
relating to this note during the year ended September 30, 1996. There were no
borrowings during fiscal 1997.
 
     Also, during the years ended September 30, 1997 and 1996, respectively, the
Company sold $32,788 and $356,000 of application platform switching products and
$0 and $2,571,731 of wholesale carrier usage to GST USA or subsidiaries and
purchased $4,466,907 and $361,000 of wholesale carrier usage from GST USA.
 
     From April 1996 through May 1997 a member of the Company's board was
compensated by GST USA for services rendered to GST USA and its subsidiaries.
 
     The Company has entered into a Deferred Compensation Trust Agreement (the
Trust) with the chairman of the Company whereby the Company funded the trust in
the amount of $144,000. The principal and related interest thereon are payable
to the chairman based on a defined payment schedule. The Company, at its sole
discretion, may at any time make additional contributions to the Trust. The
Trust is subject to claims of the Company's creditors in the event of the
Company's insolvency.
 
(14) ACCOUNTING STANDARDS ISSUED NOT YET ADOPTED
 
     In February 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 128, Earnings per Share (SFAS 128). SFAS
128 establishes a different method of computing earnings per share than is
currently required under the provisions of Accounting Principles Board Opinion
No. 15. Under SFAS 128, the Company will be required to present both basic
earnings per share and diluted earnings per share. Basic and diluted earnings
per share are expected to be comparable to the currently presented earnings per
share. SFAS 128 is effective for the consolidated financial statements for
interim and annual periods ending after December 15, 1997. Accordingly, the
Company plans to adopt SFAS 128 in the first quarter of its 1998 fiscal year and
at that time all historical earnings per share data presented will be restated
to conform with the provisions of SFAS 128.
 
     In 1997, the FASB also issued Statement No. 130, Reporting Comprehensive
Income, and Statement No. 131, Disclosures About Segments of an Enterprise and
Related Information. These statements which are effective for periods beginning
after December 15, 1997, expand or modify disclosures and accordingly, will have
no impact on the Company's reported financial position, results of operations or
cash flows.

                NOTES TO COMBINED UNAUDITED FINANCIAL STATEMENTS
                                 JUNE 30, 1998
 
NOTE 1. BASIS OF PRESENTATION
 
     The accompanying unaudited combined financial statements include the
accounts of Cherry Communications Incorporated (d/b/a Resurgens Communications
Group) ("RCG") and Cherry Communications U.K. Limited ("Cherry U.K."). Cherry
U.K.'s financial statements are prepared on a March 31 fiscal year-end. For
combination purposes, March 31, 1998 financial statements of Cherry U.K., which
were previously included in the combined entity as of December 31, 1997, have
been combined with the March 31, 1998 financial statements of RCG. Therefore,
the statement of net stockholders' deficiency and statement of cash flows
reflect an adjustment for Cherry U.K. which was previously included in fiscal
year 1997. For combination purposes, the six months ended June 30, 1997 of
Cherry U.K. have been combined with the six months ended June 30, 1997 for RCG.
 
     These financial statements do not include all the information and footnotes
required by generally accepted accounting principles for complete financial
statements. In the opinion of management, all adjustments (consisting of normal
recurring accruals) considered necessary for a fair presentation of the results
of the interim periods covered have been included. For further information,
refer to the audited combined financial statements and footnotes included
elsewhere in this Proxy.
 
     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 sales and expenses during the reporting
period. Actual results could differ from those estimates.
 
     The results of operations for the six months ended June 30, 1998 are not
necessarily indicative of the results expected for the full year. Certain
reclassifications have been made to the prior period's financial information to
conform with the presentations used in 1998.

                         REPORT OF INDEPENDENT AUDITORS
 
Board of Directors
Cherry Communications Incorporated,
  d/b/a Resurgens Communications Group
  and Cherry Communications U.K. Limited
 
     We have audited the accompanying combined balance sheet of Cherry
Communications Incorporated (d/b/a Resurgens Communications Group), and Cherry
Communications U.K. Limited (collectively referred to as the "Companies") as of
December 31, 1997, and the related statements of operations, net stockholders'
deficiency, and cash flows for the year then ended. 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 audit.
 
     We conducted our audit 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 audit provides a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the combined financial position at December 31, 1997,
of the Companies and the combined results of their operations and their cash
flows for the year then ended, in conformity with generally accepted accounting
principles.
 
     The accompanying combined financial statements have been prepared assuming
that the Companies will continue as a going concern. As more fully described in
Note 2 to the financial statements, the Companies have not complied with the
repayment schedule for several of its loan agreements and is party to
significant litigation, the outcome of which cannot be predicted. In addition,
the Companies have incurred recurring operating losses, have a working capital
deficiency and have lost virtually all of their customer base. Cherry
Communications Incorporated (d/b/a Resurgens Communications Group) filed
voluntary bankruptcy under Chapter 11 of the United States Bankruptcy Code on
October 24, 1997, and is currently operating its business as a
debtor-in-possession under the supervision of the Bankruptcy Court. These
conditions raise substantial doubt about the Companies' ability to continue as a
going concern. Although Cherry Communications Incorporated (d/b/a Resurgens
Communications Group) is currently operating as a Debtor-In-Possession under the
jurisdiction of the Bankruptcy Court, the continuation of the business as a
going concern is contingent upon, among other things, the ability to formulate a
plan of reorganization which will gain approval of the creditors and
confirmation by the Bankruptcy Court, success of future operations, and the
ability to recover the carrying amount of assets and/or the amount and
classification of liabilities. The 1997 financial statements do not include any
adjustments to reflect the possible future effect on the recoverability and
classification of assets or the amount and classification of liabilities that
may result from the outcome of the bankruptcy proceedings and related
uncertainties.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
NATURE OF BUSINESS
 
     Cherry Communications Incorporated (d/b/a Resurgens Communications Group)
("Resurgens") is a facilities-based international long-distance carrier
operating five long distance switch centers throughout the United States and
overseas, and has arrangements with domestic and foreign long distance carriers
for processing international calls. Resurgens primarily provides long distance
network services to U.S. based long distance carriers. Although there are a
number of domestic and foreign long distance carriers, a change in carriers
could disrupt Resurgens' ability to service its customers, which would result in
a possible loss of operating revenues. In August 1997 Resurgens began
experiencing a substantial decline in revenues, and in October 1997 Resurgens
began restructuring its network to improve quality and eliminate those costs not
necessary to implement Management's decision to focus its business efforts as a
carrier's carrier. Resurgens' bankruptcy filing (as described in Note 2) which
resulted in a substantial loss of customers and a corresponding write-off in
accounts receivable was an initial step in implementing the new business
strategy.
 
     The combined financial statements presented herein also include financial
statements of Cherry Communications U.K. Limited ("Cherry U.K.") which is held
under common ownership. This subsidiary has licensing and operating agreements
for international telephone access in association with Resurgens. Cherry U.K.
records an administrative revenue fee derived solely from Resurgens, based on an
agreed upon percentage of operating expense, which is eliminated in these
combined financial statements.
 
     In October 1996, WorldCom Network Services ("WorldCom") threatened to stop
providing private line services and switch services to Resurgens as a result of
Resurgens' failure to pay WorldCom. In response, Resurgens commenced a lawsuit
against WorldCom asserting various claims including substantial billing
disputes. Effective July 24, 1997 the Companies settled their litigation and
claims against WorldCom. The settlement resulted, among other things, in the
execution by Resurgens of two promissory notes in the aggregate principal amount
of $165,000 (terms of which are further described in Note 3), the issuance of
shares of Resurgens to WorldCom (representing 19.9% of outstanding shares) and
the executions of a pledge and security agreement for 51% of the outstanding
shares of Resurgens and 51% of the outstanding shares of Cherry U.K. This pledge
and security agreement gave WorldCom the ability to effectively control 71% and
51% of the voting common shares of Resurgens and Cherry U.K., respectively.
 
     After this settlement was reached WorldCom, Resurgens, Cherry U.K., James
R. Elliott (owner of 80.1% of Resurgens and sole owner of Cherry U.K.), and John
D. Phillips entered into a series of agreements, effective October 1, 1997,
whereby John D. Phillips received an option to purchase ("call right") James R.
Elliott's common stock of the combined Companies (1,000 shares of Resurgens and
50,000 shares of Cherry U.K.) for $1,000 and James R. Elliott received the right
to require ("put right") John D. Phillips to purchase the common stock of the
companies for $1,000. John D. Phillips was also granted a revocable voting proxy
for all of the shares owned and controlled by WorldCom, thereby giving him
effective control of Resurgens and Cherry U.K. In conjunction with John D.
Phillips obtaining effective control of the Companies, Resurgens filed a
voluntary petition for relief under the provisions of Chapter 11 of the Federal
Bankruptcy Code. In addition, WorldCom agreed to provide debtor-in-possession
financing (see Note 5). Effective May 8, 1998, John D. Phillips closed on his
option and acquired all of the outstanding shares of common stock of Cherry U.K.
for $1,000. James R. Elliott's exercise of his put right related to the 1,000
shares of Resurgens stock has been enjoined by the Bankruptcy Court and the Plan
of Reorganization currently provides that Resurgens stockholders will receive no
consideration under the Plan.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED)
PRINCIPLES OF COMBINATION
 
     The combined financial statements include the accounts of Resurgens and
Cherry U.K. (which is commonly controlled) (collectively, the "Companies").
Cherry U.K. was purchased by the major shareholder of Resurgens in November
1995. Cherry U.K.'s financial statements are prepared on a March 31 fiscal year
end. For combination purposes, March 31, 1998 financial statements of Cherry
U.K. have been combined with the December 31, 1997 financial statements of
Resurgens. Significant intercompany accounts and transactions have been
eliminated in combination.
 
CASH AND CASH EQUIVALENTS
 
     The Companies consider all highly liquid investments with a maturity of
three months or less when purchased to be cash equivalents.
 
PROPERTY AND EQUIPMENT
 
     Property and equipment are stated at cost. Depreciation and amortization
are generally computed using the straight-line method over the estimated useful
lives of the related assets as indicated below:
 
<TABLE>
<S>                                                         <C>
Telecommunications equipment..............................  5-10 years
Furniture, fixtures and equipment.........................  4-5 years
Leasehold improvements....................................  Life of lease
</TABLE>
 
     In the event facts and circumstances indicate the cost of any long-lived
assets may be impaired, an evaluation of recoverability would be performed. If
an evaluation is required, the estimated future undiscounted cash flows
associated with the assets would be compared to the carrying amount of the
assets to determine if a write down to fair value may be required.
 
REVENUE RECOGNITION
 
     Revenues are derived primarily from the provision of long-distance
telecommunications services and are recognized when the services are provided.
 
NEW ACCOUNTING PRONOUNCEMENTS
 
     In June 1997 the FASB issued Statement of Financial Accounting Standards
No. 130, "Reporting Comprehensive Income" ("SFAS 130"). SFAS 130 requires that
all items that are required to be recognized under accounting standards as
components of comprehensive income be reported in a financial statement that is
displayed with the same prominence as other financial statements. SFAS 130
requires that an enterprise classify items of other comprehensive income by
their nature in a financial statement and display the accumulated balance of
other comprehensive income separately from retained earnings and additional
paid-in capital in the equity section of the statement of financial position.
SFAS 130 is effective for fiscal years beginning after December 15, 1997.
 
     The Companies intend to adopt the provisions of SFAS 130 in 1998 and do not
expect its application to have a material impact on the financial position or
results of operations of the Companies.
 
FINANCIAL INSTRUMENTS
 
  Concentration of Credit Risk
 
     Financial instruments that potentially subject the Companies to significant
concentrations of credit risk consist principally of cash and cash equivalents,
trade accounts receivable, accounts payable and long term debt.

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED)
     The Companies maintain cash and cash equivalents and certain other
financial instruments with various financial institutions. The Companies' policy
is designed to limit exposure at any one institution by performing periodic
evaluations of the relative credit standing of those financial institutions.
 
  Fair Value of Financial Instruments
 
     The fair value of the Companies' financial instruments classified as
current assets or liabilities, including cash and cash equivalents, accounts
receivable, and accounts payable approximate carrying value, principally because
of the short maturity of these items.
 
     The carrying amounts of the long-term debt payable approximate fair value
due to the interest rates on these agreements approximating the Companies'
incremental borrowing rates, and the fair values of capitalized lease
obligations approximate carrying value based on their effective interest rates
compared to current market rates.
 
SIGNIFICANT CUSTOMERS
 
     The Companies' revenues are derived from a variety of customers including
one customer, which accounted for 19% of the Companies' revenues during 1997.
 
ADVERTISING COSTS
 
     Pursuant to American Institute of Certified Public Accountants (AICPA)
Statement of Position No. 93-7, "Reporting on Advertising Cost," the Companies
expensed advertising costs of $2,226 as incurred in 1997.
 
COST OF SERVICES AND PRODUCTS
 
     Cost of services include payments primarily to local exchange carriers
("LECs") and interexchange carriers, primarily for access and transport charges.
 
INCOME TAXES
 
     Due to Resurgens' conversion from a subchapter S Corporation to a C
Corporation as of August 1, 1997, Resurgens began accounting for income taxes
under the liability method. Under this method, deferred income taxes are
recorded to reflect the net tax effects of temporary differences between the
carrying amounts of assets and liabilities for financial reporting and the
amounts for income tax purposes.
 
     For the period prior to August 1, 1997, all taxable losses were allocated
to the owners of Resurgens. Accordingly no income taxes are reflected for
Resurgens in the accompanying financial statements for the period prior to the
conversion. Cherry U.K. accounted for income taxes under the liability method
for fiscal 1997.
 
USE OF ESTIMATES IN PREPARING FINANCIAL STATEMENTS
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results may differ from those estimates and such
differences could be material.

     Translation adjustments arising from combining Cherry U.K. are reflected

2. PETITION FOR RELIEF UNDER CHAPTER 11 BANKRUPTCY
 
     On October 24, 1997, Resurgens filed a voluntary petition for relief under
the provisions of Chapter 11 of the Federal Bankruptcy Code ("Chapter 11") in
the United States Bankruptcy Court for the Northern District of Illinois (the
"Court"). Cherry U.K. was not included in this bankruptcy filing. Under Chapter
11, certain claims against Resurgens in existence prior to the filing for relief
under the federal bankruptcy laws are stayed while Resurgens continues business
operations as a Debtor-in-Possession subject to the supervision of the Court.
Management filed a plan of reorganization on June 15, 1998 which contemplates
emergence in the third quarter of 1998. There can be no assurance at this time
that a plan of reorganization will be approved or confirmed by the Bankruptcy
Court, or that such plan will be consummated.
 
     After an exclusivity period, creditors of Resurgens have the right to
propose alternative plans of reorganization. Any plan of reorganization, among
other things, is likely to result in material dilution of the equity of existing
stockholders as a result of a possible issuance of equity to creditors or new
investors.
 
     The accompanying financial statements have been prepared on a going concern
basis, which contemplates continuity of operations, realization of assets and
liquidation of liabilities in the ordinary course of business. However, as a
result of the Chapter 11 filing and circumstances relating to this event,
including Resurgens' leveraged financial structure and losses from operations,
such realization of assets and liquidation of liabilities is subject to
significant uncertainty. While under protection of Chapter 11, Resurgens may
sell or otherwise dispose of assets and liquidate or settle liabilities, for
amounts other than those reflected in the financial statements. Further, a plan
of reorganization could materially change the amounts reported in the financial
statements. Accordingly such financial statements do not give effect to all
adjustments of the carrying value of assets or liabilities that might be
necessary as a consequence of a plan of reorganization or the inability of the
Companies to continue as a going concern.

2. PETITION FOR RELIEF UNDER CHAPTER 11 BANKRUPTCY -- (CONTINUED)
     The ability to continue as a going concern is dependent upon, among other
things, confirmation of a plan of reorganization, future profitable operations,
and the ability to generate sufficient cash from operations and financing
arrangements to meet obligations.
 
3. LIABILITIES SUBJECT TO COMPROMISE
 
     The principal categories of claims classified as liabilities subject to
compromise under the reorganization proceedings are identified below. These
amounts may be subject to future adjustment depending on the Court's action,
further developments with respect to disputed claims, determination as to the
value of any collateral securing claims, and other events. Additional claims may
arise resulting from rejection of additional executory contracts or unexpired
leases by Resurgens.

3. LIABILITIES SUBJECT TO COMPROMISE -- (CONTINUED)
1998 interest payment due on the $115,000 note. Remedies of default are not
waived under this agreement by any failure or delay by any party in exercising
any remedy of default.
 
     On April 2, 1996 Resurgens settled a litigation case with Illinois Capital
Group related to delinquent payments for leased switching equipment. In
connection with this settlement, a promissory note was executed for
approximately $1,300. The note required monthly payments beginning April 15,
1996 with a penalty amount of $250 if Resurgens did not make payments when due.
Resurgens ceased payment on this note in mid 1997 and therefore this penalty
amount has been added to the principal balance.
 
     Resurgens entered into a settlement agreement with Esplanade at Locust
Point Limited Partnership ("Esplanade") on January 29, 1996 which released
Resurgens from litigation claims involving leased office space. In connection
with this settlement, a promissory note was issued in the amount of $4,000, with
monthly payments of $100 to begin in March 1996, with no interest. Resurgens
failed to remit the required monthly payments during 1997. The agreement stated
that an additional $1,000 would be assessed and due if the companies failed to
meet the required payment schedule. Esplanade filed a claim against Resurgens
for the outstanding balance of the loan plus the additional penalty amount.
Prior to December 31, 1997, a judgment was reached in this case and an
additional amount of $894 was granted to Esplanade. This amount is subject to an
interest rate of 12.5% and is included in the principal balance amount at
December 31, 1997.
 
     The Eastern Telecom installment note was signed on August 1, 1997, based
upon judicial court settlement, for $190. The amount relates to non-performance
of a purchase agreement for switching equipment by Resurgens.
 
     As part of the Chapter 11 reorganization process, Resurgens has attempted
to notify all known or potential creditors of the Chapter 11 filing for the
purpose of identifying all pre-petition claims against Resurgens. Generally,
creditors whose claims arose prior to the Petition Date had until February 6,
1998 ("Bar Date") to file claims or be barred from asserting claims in the
future. Claims arising from rejection of executory contracts by Resurgens, and
claims related to certain other items were permitted to be filed within other
dates as set by the Court.
 
     Differences between amounts shown by Resurgens and claims filed by
creditors are being investigated and will either be resolved or adjudicated. The
ultimate amount of and settlement terms for such liabilities are subject to the
confirmed plan of reorganization and are not presently determinable. The total
amount of proofs of claims filed in Court approximate $434,000, while the amount
accrued by Resurgens at December 31, 1997 is $336,751. This difference of
approximately $95,000 pertains to claims that management believes to be
duplicate claims, amounts relating to outstanding litigation (See Note 11) and
other disputed claims for which management is unable to predict the ultimate
outcome of and therefore, no provision has been recorded in the financial
statements for this difference.

5. DEBTOR-IN-POSSESSION (DIP) FINANCING
 
     In November 1997, the Court authorized Resurgens to enter into a financing
agreement with WorldCom in order to facilitate continued operations as a
debtor-in-possession. The terms of this financing agreement originally provided
for maximum advances thereunder to $19,000 and required repayment on April 30,
1998 at 12% interest.
 
     On April 16, 1998 the financing agreement was amended to provide for an
increased maximum amount of $25,000 and an extended term through July 31, 1998.
As of June 5, 1998, the Company had borrowed an additional $13,700.
 
6. CAPITALIZED LEASE OBLIGATIONS
 
     The Companies lease telecommunications and other equipment through
capitalized lease arrangements.
 
     Future minimum lease payments on these capitalized lease obligations at
December 31, 1997 are as follows:

     The net carrying value of assets under capital leases was $35,900 at
December 31, 1997, and is included in property and equipment. Amortization of
these assets is included in depreciation expense.
 
7. EMPLOYEE 401(K) PLAN
 
     Effective January 1, 1997, Resurgens established a defined contribution
savings plan, intended to qualify under IRS Code Section 401(k), available to
all employees who complete six months of service and are at least age 21.
Employees may contribute up to 15% of their salary per year, subject to
statutory limitations, and Resurgens matches 100% of employee contributions up
to 5% of each employee's salary. Resurgens' matching contributions vest 20% per
year. Resurgens' expense under the plan during 1997 amounted to approximately
$98.
 
8. INCOME TAXES
 
     For the period from inception through July 31, 1997, Resurgens elected to
have its income taxed directly to its individual shareholders under the
provisions of Subchapter S of the Internal Revenue Code ("the Code").
Accordingly, no deferred income taxes were established for Resurgens. Effective
August 1, 1997, the S-Corporation election was terminated due to a change in
ownership and Resurgens is now subject to federal and state income taxes. Upon
conversion to C corporation status, Resurgens recorded a net deferred tax asset
which was fully offset by the establishment of a valuation reserve. Accordingly,
no charge or benefit was made to the income tax provision to reflect the impact
of this change in tax status.

8. INCOME TAXES -- (CONTINUED)
     Effective August 1, 1997, the accompanying financial statements reflect
provisions for income taxes computed in accordance with the requirements of
Statement of Financial Accounting Standards ("SFAS") No. 109. With respect to
Cherry U.K., the accompanying financial statements reflect provisions for income
taxes calculated under the provisions of SFAS No. 109 since acquisition. For the
period prior to the change in tax status, the provision has been presented on a
pro forma basis as if Resurgens had been liable for federal and state income
taxes since January 1, 1997.
 
     The Companies have generated significant net operating losses ("NOLs") both
in the United States and in the United Kingdom. These NOLs may be available to
offset future taxable income, subject to the limitations discussed below.
Resurgens has generated NOL carryforwards totaling $128,000 in the United States
after the date of the conversion from S-Corporation to C-Corporation status.
Cherry U.K. has NOLs available at December 31, 1997 approximating $1,500 in the
United Kingdom. The United States federal NOL generated in 1997 expires in the
year 2012, while the United Kingdom NOLs do not expire.

liabilities are:

     Rent expense for the year ended December 31, 1997 was approximately $3,538.
 
10. RELATED PARTY TRANSACTIONS
 
     Effective April 1, 1997, Resurgens entered into a ten-year lease agreement
for an office building with shareholder related trusts. Until occupancy on or
about January 1, 1998, Resurgens is required to pay 50% of the monthly lease
amount or approximately $11 per month. For the year ended December 31, 1997, the
Companies recorded rent expense of $200 associated with this lease. In December
1997, Resurgens recorded a liability of $444 for rejecting the lease in
accordance with Chapter 11 provisions.
 
     During fiscal 1997, Resurgens utilized WorldCom, a shareholder, for
transport services aggregating $27,834, which have been expensed by the
Companies in cost of service. The amount owed to WorldCom at December 31, 1997
is $188,992, of which $178,863 is recorded as liabilities subject to compromise.
 
     Effective April 1998, Resurgens entered into a Carrier Service Agreement
with WorldCom pursuant to which WorldCom is obligated to purchase international
long distance services up to $25,000 a month provided the services are of
acceptable quality and the rates are at least equal to rates from other third
parties. The contract is for a one year initial term but automatically renews
each month, subject to a one year termination notice.
 
11. LITIGATION
 
     The Companies are subject to numerous lawsuits, investigations and claims
(a number of which involve amounts that are material to these financial
statements) arising out of the conduct of its business, including those relating
to commercial transactions and regulatory matters. Such items generally relate
to claims made previous to Resurgens filing bankruptcy; therefore, the ultimate
liability of Resurgens is generally included in the liabilities subject to
compromise (see Note 3).
 
     Resurgens is party to an action with AT&T in which AT&T filed suit against
Resurgens. Resurgens purchased long distance and international service from AT&T
from January 1996 through February 1997, and disputed the accuracy of certain
charges which prompted AT&T to terminate all services. AT&T seeks in excess of
$16,000 for alleged unpaid services. Resurgens has filed a counterclaim against
AT&T, alleging offset claims for the full amount of AT&T's claims, resulting
from alleged inaccurate billing by AT&T. Resurgens also alleges false and
deceptive advertising claims, unfair competition and deceptive business
practices claims against AT&T. Resurgens has recorded all disputed invoices
aggregating $16,528 and cannot predict the ultimate outcome of this case.

11. LITIGATION -- (CONTINUED)
     Resurgens is party to an action with MidCom Communications Inc. (MidCom).
Resurgens initially sued MidCom during 1996 and MidCom subsequently filed a case
against Resurgens. Resurgens sold a portion of its commercial customer base to
MidCom during 1995, but did not receive the full payment for the customer base
and sued MidCom for $16,200. MidCom filed a counter suit against the Company
asserting that Resurgens' actions related to the sale of the customer base
allegedly breached the contract, violated the Uniform Commercial Code, and
constituted tortious interference with the contract. MidCom filed a $36,000
proof of claim in Resurgens' bankruptcy case. The litigation of both parties has
been stayed and remanded to a bankruptcy court hearing. Given the uncertainty of
this matter, Management is unable to predict the ultimate outcome of this case
and accordingly, has not accrued any liability for this claim.
 
     Coast to Coast Plus, Inc., a former customer, filed suit in November 1996
alleging that it suffered $10,000 in damages from Resurgens' "wrongful"
termination of its long-distance telecommunications services and overbillings
for services Resurgens did not provide. Resurgens filed an answer denying
liability and filed a counterclaim and a third party claim against the
principals of Coast to Coast which asserted four claims: two RICO claims, a
fraud claim, and a breach of contract, including $250 owed for long-distance
services. Management is unable to predict the ultimate outcome of this case and
accordingly, has not accrued any liability for this claim.
 
     First Premier Bank asserted a claim for approximately $44,000 against
Cherry Payment Systems and Dallas Leasing Group, which are companies that were
merged into Resurgens in prior years, for non-payment on past due loans. First
Premier Bank did not file a proof of claim as of the bar date with the Court and
therefore management does not believe it is obligated for this amount. Given the
uncertainty of this asserted claim, Management can not predict the ultimate
outcome of this matter and accordingly, has not accrued any liability for this
claim.
 
     The Companies are also involved in other claims, inquiries and litigation
arising in the ordinary course of business. The Companies believe that these
matters, taken individually or in the aggregate, would not have a material
adverse impact on the Companies' financial position or results of operations.
 
12. SUBSEQUENT EVENTS
 
On May 12, 1998 the Companies and World Access, Inc. ("World Access") entered
into a merger agreement whereby World Access will acquire the Companies. The
agreement is subject to, among other things, Bankruptcy Court approval, certain
monthly revenue and gross margin levels, confirmation of Resurgens' Plan of
Reorganization and World Access shareholder approval. Pursuant to the terms of
the agreements, the creditors of Resurgens and shareholders of Cherry U.K. will
receive 3,125,000 and 625,000 shares of World Access common stock, respectively,
in the aggregate at the closing of the mergers. In addition, Resurgens'
creditors and Cherry U.K. shareholders would have the right to receive
additional consideration of up to 6,250,000 and 1,250,000 shares of World Access
common stock, respectively, over the next two and one-half years contingent upon
the achievement of certain financial criteria by the Companies.

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS
 
BOARD OF DIRECTORS
  CHERRY COMMUNICATIONS INCORPORATED AND CHERRY COMMUNICATIONS U.K. LIMITED
 
     We have audited the accompanying balance sheet of Cherry Communications
Incorporated and Cherry Communications U.K. Limited (collectively referred to as
the "Companies") as of December 31, 1996 and the related combined statements of
operations, stockholder's equity (deficit) and cash flows for each of the two
years in the period ended December 31, 1996. These financial statements are the
responsibility of the Companies' 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 financial statements referred to above present fairly,
in all material respects, the combined financial position of Cherry
Communications Incorporated and Cherry Communications U.K. Limited as of
December 31, 1996, and the combined results of their operations and their
combined cash flows for each of the two years in the period ended December 31,
1996 in conformity with generally accepted accounting principles.
 
     The accompanying financial statements have been prepared assuming that the
Companies will continue as a going concern. As discussed in Notes 2 and 9 to the
financial statements, the Company incurred substantial losses in 1995 and 1996
and have disputed significant net accounts payable balances due its primary
vendor. Although the dispute has been settled, as discussed in Note 10, and 1996
balances payable have been reduced, significant balances converted to notes
payable remain. The Companies' ability to obtain an equity infusion or
replacement financing for these notes is limited by the terms and collateral
arrangements of the settlement. The terms of the settlement agreement will
continue the Companies' dependence on this vendor as one of the Companies'
primary long distance carriers. These matters raise substantial doubt about the
Companies' ability to continue as a going concern. Management's plans in regard
to these matters are also described in Note 2. Continuation of the Companies is
dependent upon the Companies' ability to return to profitability and to achieve
sufficient cash flow from operations, additional debt or equity. The
accompanying combined statements do not include any adjustments relating to the
recoverability and classification of recorded asset amounts or the amounts and
classification of liabilities that might be necessary should the Companies be
unable to continue as a going concern.

                     NOTES TO COMBINED FINANCIAL STATEMENTS
                               DECEMBER 31, 1996
 
NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
NATURE OF BUSINESS
 
     Cherry Communications Incorporated ("Cherry") commenced operations in 1991
as a successor through merger of five businesses operating in the payment
processing and credit authorization industry, including leasing of bank card
processing machinery. During 1992, Cherry discontinued the operations of the
five businesses and began the new business of a non-switch-based reseller of
long distance services to residential and commercial customers throughout the
United States. In late 1994, Cherry acquired its first long distance switch. As
of December 31, 1996, Cherry is a switch-based carrier operating nine long
distance switch centers throughout the United States and overseas, and has
arrangements with foreign carriers for processing of international calls. Cherry
provides its long distance network services to resellers, agents and end users
consisting of business and residential customers. At December 31, 1996, Cherry
primarily uses one long distance carrier, WorldCom, Inc., as its major long
distance carrier. Although there are a number of long distance carriers, a
change in carriers could disrupt Cherry's ability to service its customers,
which could result in a possible loss of operating revenues.
 
     The combined financial statements presented herein also include financial
statements of Cherry Communications U.K. Limited ("Cherry U.K.") which is held
under common ownership. This affiliate has licensing and operating agreements
for international telephone access in association with Cherry.
 
PRINCIPLES OF COMBINATION
 
     The combined financial statements include the accounts of Cherry and Cherry
U.K. (collectively, the "Companies"). Cherry U.K. was purchased by the
shareholder of Cherry in November 1995. Cherry U.K.'s financial statements are
prepared on a March 31 fiscal year end. For combination purposes, Cherry U.K.'s
financial statements as of and for the year ended March 31, 1997 and for the
period ended March 31, 1996 have been combined with the December 31, 1996 and
1995 financial statements of Cherry, respectively. Significant intercompany
accounts and transactions have been eliminated in combination.
 
CASH AND CASH EQUIVALENTS
 
     The Companies consider all highly liquid investments purchased with a
maturity of three months or less to be cash equivalents. Cash equivalents
consist of money market fund investments and short-term certificates of deposit.
Exclusive of cash in banks, cash equivalents at December 31, 1996 approximate
fair value. At December 31, 1996, the Companies' certificates of deposits
approximated $2,176,000. The certificates of deposit are collateral for the
Companies' line of credit agreement (note 4).
 
INVESTMENTS
 
     Short-term investments are comprised of equity securities. Investment
securities are classified as available-for-sale and are stated at fair value as
determined by quoted prices on exchanges. During the year ending December 31,
1996, all of the Companies' investment securities were transferred to the
Companies' primary vendor in partial settlement of outstanding line charges. The
fair value of these securities at the date of transfer approximated $2,357,000.
The Companies recognized a loss of $643,000 from the transfer. During the year
ending December 31, 1995, proceeds from the sale of investment securities was
$423,000 with no realized gain or loss recognized.
 
PROPERTY AND EQUIPMENT
 
     Property and equipment are stated at cost. Depreciation and amortization
are generally computed using the straight-line method over the estimated useful
lives of the related assets.

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED)
INCOME TAXES
 
     Income taxes on net taxable earnings are payable personally by the
stockholder, pursuant to an election under Subchapter S of the Internal Revenue
Code, which states Cherry is not taxed as a corporation. Accordingly, no
provision has been made for Federal income taxes for Cherry. Cherry U.K. income
taxes are not material to the combined financial statements.
 
REVENUE RECOGNITION
 
     Revenues are recorded upon placing of calls or rendering of other related
services.
 
CONCENTRATION OF CREDIT RISK
 
     Financial instruments which potentially subject the Companies to
concentration of credit risk consist principally of trade receivables.
Concentration of credit risk with respect to these receivables is generally
diversified because the Companies' customer base includes many entities spread
across a large geographic area. The Companies routinely address the financial
strength of its customers and, as a consequence, believe that its receivable
credit risk exposure is limited.
 
USE OF ESTIMATES IN PREPARING FINANCIAL STATEMENTS
 
     In preparing financial statements in conformity with generally accepted
accounting principles, management is required to make estimates and assumptions
that affect the reported amounts of assets and liabilities and the disclosure of
contingent assets and liabilities at the date of the financial statements and
revenues and expenses during the reporting period. Actual results could differ
from those estimates.

NOTE 2. GOING CONCERN
 
     The accompanying financial statements have been prepared assuming the
Companies will continue as a going concern. The Companies have sustained
significant losses in 1995 and 1996, and has a deficit in stockholder's equity
of approximately $153.4 million at December 31, 1996. As discussed in Note 9 --
Litigation, the Companies have various disputes with carriers for out-bound and
in-bound line charges which affect timing and amounts of collections and
payments. The most significant of these disputes is with WorldCom, Inc.
("WorldCom"), historically the Companies' primary carrier. As discussed in Note
10 -- Subsequent Events, the dispute with WorldCom has been settled as of July
24, 1997, resulting in, among other matters, a settlement of outstanding net
liabilities of $202,415,000 at July 15, 1997 ($175,633,000 at December 31, 1996)
for $165,000,000 in notes. The first new note of $50,000,000 is due on December
31, 1997. The second new note of $115,000,000 is due in quarterly installments
commencing October 23, 1998 through June 23, 2000, with interest payable
quarterly at 10% per annum.
 
     Other terms of the settlement require the Companies to continue to pledge
all assets as collateral for the notes, except for equipment under capitalized
lease obligations; the Companies will issue shares representing 19.9% ownership
to WorldCom; and the sole shareholder must pledge 51% of total outstanding
shares as collateral. WorldCom will subordinate its collateral position up to
$100,000,000 for new borrowings by the Company if 75% of the proceeds from a
single new borrowing of up to $70.0 million or 50% of the proceeds from a single
new borrowing over $70.0 million are used to pay WorldCom.
 
     These developments continue to have a material adverse effect and limit the
Companies' ability to meet its obligations as they come due and to obtain
financing or an equity infusion. The Companies' actions to address its current
liquidity constraints and its financial performance include negotiations with
potential lenders or equity participants. However, there can be no assurances
that the Companies' actions will improve its financial performance or liquidity
position or that it can avoid default on the December 31, 1997 payment of the
$50,000,000 note obligation.

(1) See Note 10 -- Subsequent Events.
 
     In January 1996, Cherry and Esplanade at Locust Point ("Esplanade") entered
into an agreement as a settlement on an office property lease. As part of the
$5,000,000 settlement, Cherry agreed to pay Esplanade $1,000,000 on February 9,
1996 and then make 40 monthly payments of $100,000 beginning March 1996.
Interest on the note was imputed at a rate of 12.5% as no interest rate was
explicitly stated in the agreement.
 
     In March, 1996, Cherry entered into an agreement with Illinois Capital
Group ("ICG") as a settlement on equipment leases sold to ICG. Under the terms
of the agreement, Cherry is to make 17 equal monthly payments of $60,500,
including interest stated at 10% commencing April 15, 1996, with the final
payment of approximately $56,900 in principal and interest due on September 15,
1997. In the event Cherry or the shareholder interferes with existing leases
under the security agreement, an additional $250,000 penalty provision is due
ICG.
 
     Principal amounts due under all of these debt arrangements at December 31,
1996 mature as follows (in thousands):

USAGE AND DEDICATED CIRCUIT AGREEMENTS
 
     The Companies have entered into agreements with various long distance
providers which require minimum usage. The Companies have also entered into
agreements with various long distance carriers for dedicated circuits. These
agreements guarantee the provider a base monthly charge regardless of the actual
volume of usage or use of dedicated circuits by the Companies or their
customers.
 
NOTE 8. RELATED PARTY TRANSACTIONS
 
     Effective April 1, 1997, Cherry entered into a ten-year lease agreement for
an office building with shareholder related trusts. Until occupancy on or about
January 1, 1998, Cherry is required to pay 50% of the monthly lease amount or
approximately $11,000 per month. Lease payment terms, as determined by
independent appraisers, over the ten-year period range from $265,000 to $345,000
annually. At December 31, 1996, Cherry had recorded an initial deposit of
$100,000 for the lease. Tenant finish and other improvements to the office
facility are expected to approximate $4,000,000.
 
NOTE 9. LITIGATION
 
     The Companies are subject to a number of lawsuits, investigations and
claims (some of which involve substantial amounts) arising out of the conduct of
their business, including those relating to commercial transactions and
regulatory matters. One such lawsuit was brought by Cherry against Digital
Communications of America, WorldCom Network Services Inc. and WorldCom Inc.
(collectively referred to as "WorldCom"), asserting various claims including
substantial billing disputes. WorldCom asserted various counterclaims.
Subsequent to December 31, 1996, the parties reached a settlement. See Note 10
Subsequent Events.
 
     Cherry is also party to an action with AT&T in which AT&T filed suit
against Cherry. Cherry purchased long distance and international service from
AT&T from January, 1996 through February, 1997. Cherry disputed the accuracy of
certain charges and AT&T terminated all services. AT&T seeks $17.2 million for
alleged unpaid services. Cherry has counterclaimed against AT&T, alleging offset
claims for the full amount of AT&T's claims, resulting from alleged inaccurate
billing by AT&T. Cherry also alleges false and deceptive advertising claims,
unfair competition and deceptive business practices claims against AT&T. The
litigation is at an early stage. Parties have not yet engaged in discovery.
Cherry has recorded all disputed invoices.
 
     In addition, the Companies are also party to an action with a U.K.-based
carrier in which the carrier filed suit in the U.K. against the Companies. The
Companies purchased international service from this carrier from February, 1996
through April, 1997. The carrier seeks approximately $5.0 million for alleged
unpaid services and finance charges. The litigation is at an early stage. The
Companies recorded all of the carrier's invoices.
 
     The Companies are also involved in other litigation concerning significant
collection matters, some of which have resulted in counterclaims. Based on
advice of counsel, the Companies believe such matters will be resolved within
the limits of its collection reserves.
 
     Coast to Coast Plus, Inc., a former carrier customer, filed suit in
November, 1996 alleging that it suffered $10 million in damages from Cherry's
"wrongful" termination of its long-distance telecommunication services and
overbillings for services Cherry did not provide. Cherry filed an answer denying
liability and filed a counterclaim and a third party claim against the
principals of Coast to Coast which asserted four claims: two RICO claims, a
fraud claim, and a breach of contract, including $250,000 owed for long-distance
services. Deposition and discovery is underway. Based on advice of counsel,
Cherry believes this litigation will not have a material effect on the combined
financial position.
 
     The Companies are also involved in other miscellaneous claims, inquiries
and litigation arising in the ordinary course of business. The Companies believe
that these matters, taken individually or in the aggregate,

NOTE 9. LITIGATION -- (CONTINUED)
would not have a material adverse impact on the Companies' combined financial
position or results of operations.
 
NOTE 10. SUBSEQUENT EVENTS
 
     Effective April 1, 1997, Cherry entered into a new lease with a related
party for new office facilities. See Note 8 -- Related Party Transactions.
 
     On July 2, 1997, Cherry entered into a letter of intent with EqualNet
Holding Corp. ("EqualNet") for a proposed business transaction expected to be a
merger of the Company into EqualNet, with Cherry's stockholder retaining 91% of
the combined entity. The transaction is expected to be treated as a reverse
purchase acquisition and is subject to due diligence, shareholder approval and
certain other preconditions.
 
     Effective July 24, 1997, Cherry settled its litigation and claims against
WorldCom. The settlement provides for, among other matters, the following:
 
          (1) All claims of both parties as of July 15, 1997 (estimated by
     Cherry to be approximately $202.4 million net accounts, notes and interest
     payable) to be converted to two notes payable in the individual amounts of
     $50.0 million and $115.0 million. The first note of $50.0 million is
     non-interest bearing and due December 31, 1997. The second note of $115.0
     million is due in quarterly installments commencing October 23, 1998
     through July 23, 2000. Interest is payable at 10% per annum and is due on
     March 31, 1998, June 30, 1998, July 23, 1998 and quarterly thereafter.
 
          (2) WorldCom is granted continued security interests in all of the
     assets of Cherry, except for the limited security interest granted to
     Cherry's bank up to $2.0 million.
 
          (3) The sole shareholder executes a pledge and security agreement
     granting a first-priority interest in 51% of the outstanding shares of
     Cherry subject to anti-dilution provisions.
 
          (4) On August 1, 1997, Cherry is required to issue common shares
     equivalent to 19.9% of the then-outstanding shares of Cherry to WorldCom,
     also subject to anti-dilution provisions.
 
          (5) Similar pledge (51%) agreement requirement applies to the
     shareholder's interest in Cherry U.K..
 
          (6) WorldCom will subordinate its security interests up to $100.0
     million for new borrowings if certain proceeds of such borrowings are
     remitted to WorldCom (75% for a single borrowing up to $70.0 million or 50%
     for a single borrowing over $70 million).
 
          (7) If Cherry repays both notes by December 30, 1997, it or its
     nominee may repurchase the transferred shares totaling 19.9% for $10.
 
     Cherry has reflected the settlement reduction of net payables of
approximately $37.4 million as a reduction of disputed costs and finance charges
of $11.4 million and $26.0 million for the year ended December 31, 1996 and the
six months ended June 30, 1997, respectively.

                         REPORT OF INDEPENDENT AUDITORS
 
To the Board of Directors and Shareholders of Telco Systems, Inc.
 
     We have audited the accompanying consolidated balance sheets of Telco
Systems, Inc. as of August 30, 1998 and August 31, 1997, and the related
consolidated statements of operations, shareholders' equity, and cash flows for
each of the three years in the period ended August 30, 1998. Our audits also
included the accompanying financial statement schedule. These financial
statements and schedule 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 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 consolidated financial position of
Telco Systems, Inc. at August 30, 1998, and August 31, 1997, and the
consolidated results of its operations and its cash flows for each of the three
years in the period ended August 30, 1998, in conformity with generally accepted
accounting principles. Also, in our opinion, the related financial statement
schedule, when considered in relation to the financial statements taken as a
whole, presents fairly, in all material respects, the information set forth
therein.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 1  SIGNIFICANT ACCOUNTING POLICIES
 
     Principles of Consolidation.  The financial statements consolidate the
accounts of Telco Systems, Inc., and its subsidiaries (the Company).
Intercompany accounts and transactions have been eliminated. The Company's
fiscal year ends on the last Sunday in August which included 52 weeks in fiscal
1998 and fiscal 1996 and 53 weeks in fiscal 1997. Certain amounts reported in
prior years have been reclassified to be consistent with the current year's
presentation.
 
     The Company has 50% limited partnership interests in two real estate
partnerships which are accounted for by the equity method of accounting. The
aggregate net investment in these partnerships on the accompanying balance
sheets is not material (See Note 6).
 
     New Accounting Standards.  In June 1997, the FASB issued Statement No. 130,
"Reporting Comprehensive Income" (SFAS 130). SFAS 130 establishes standards for
reporting comprehensive income and its components in a full set of general
purpose financial statements. SFAS 130 requires that items to be recorded in
comprehensive income, which include unrealized gains/losses on marketable
securities classified as available-for-sale and cumulative translation
adjustments, be displayed with the same prominence as other financial statement
items. The Company does not believe the adoption of SFAS 130 will have a
material impact on the Company's financial results or financial condition. SFAS
130 is required to be adopted in the Company's financial statements for the year
ending August 29, 1999.
 
     In June 1997, the FASB issued Statement No. 131, "Disclosures about
Segments of an Enterprise and Related Information," (SFAS 131). SFAS 131
establishes standards for the way public business enterprises report information
about operating segments in annual financial statements and requires those
enterprises to report selected information about operating segments in interim
financial reports issued to shareholders. SFAS 131 also establishes standards
for related disclosures about products and services, geographic areas, and major
customers. SFAS 131 is required to be adopted in the Company's financial
statements for the year ending August 29, 1999. The adoption of SFAS 131 will
have no impact on the Company's financial results or financial condition, but
may result in certain disclosures of segment information.
 
     Use of Estimates in the Preparation of 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 could differ from those estimates.
 
     Revenue Recognition.  In general, the Company recognizes revenue from
product sales at the time of shipment. In certain contractual situations,
revenue is recognized when the product is accepted by the customer.
 
     Product Warranty.  Expected future product warranty liability is provided
for when the product is sold.
 
     Cash Equivalents and Marketable Securities.  The Company classifies all of
its marketable securities as available-for-sale securities. These securities are
stated at their fair value. There are currently no unrealized holding gains and
losses. The Company considers all highly liquid investments with maturity of 91
days or less to be cash equivalents. Those instruments with maturities greater
than 91 days are classified as marketable securities. Cash equivalents and
marketable securities are carried at market, and consist of U.S. Government
securities, bank certificates of deposit and corporate issues. All securities
mature within twelve months.
 
     Inventories.  Inventories are stated at the lower of cost or market. The
cost of products sold is based on standard costs, which approximate actual costs
as determined by the first-in, first-out method.

     In January 1998, the Company entered into an agreement to subcontract the
manufacture of certain products. The agreement commits the Company to annual
purchases of $25 million for the three years ending March 2001. Included in
Other Current Assets at August 30, 1998 is $2.1 million of advances to the
subcontractor.
 
     Plant and Equipment.  Additions to plant and equipment are recorded at
cost. Depreciation is determined by using the straight-line method over the
estimated useful lives of the assets -- three to eight years. Leasehold
improvements are amortized on a straight-line basis over the shorter of their
estimated useful life or the lease term.
 
     Plant and equipment, at cost, at fiscal year end were as follows:

     Intangible and Other Assets.  Intangible assets arising in connection with
business acquisitions were $7,450,000 and $7,122,000 at August 31, 1998 and
August 31, 1997, respectively. They are amortized over lives ranging from five
to twenty-five years using the straight-line method, with an average remaining
life of 8.4 years. The carrying value of goodwill is reviewed periodically based
on the undiscounted cash flows of the entities acquired over the remaining
amortization period. Should this review indicate that goodwill will not be
recoverable, the carrying value will be reduced by the estimated shortfall of
undiscounted cash flows.
 
     Concentrations of Credit Risk.  Financial instruments which potentially
subject the Company to concentrations of credit risk consist primarily of cash
equivalents, short-term investments, and accounts receivable. The Company's
temporary cash investments, which are principally limited to U.S. Government
securities and bank certificates of deposit, are subject to minimal risk. The
Company routinely assesses the financial strength of its customers and, as a
consequence, believes that its trade accounts receivable credit risk exposure is
limited.
 
     Earnings (Loss) Per Share.  In February 1997, the Financial Accounting
Standards Board issued Statement No. 128, "Earnings Per Share" (FAS 128), which
the Company adopted in the second quarter of fiscal 1998. The Company has
restated all prior period per share amounts to comply with the requirements of
FAS 128. Under the new requirements, primary and fully diluted earnings per
share were replaced by basic and diluted earnings per share. Basic earnings per
share is calculated by dividing net income or loss by the weighted average
number of common shares outstanding during the periods. Diluted earnings per
share is calculated by dividing net income or loss by the sum of the weighted
average number of common shares outstanding plus all additional common shares
that would have been outstanding if potentially dilutive common shares had been
issued. Potentially dilutive common shares were excluded from the diluted
calculation for those periods in which the Company reported a net loss. See Note
9 for a description of the Company's stock plans.

NOTE 2  DESCRIPTION OF BUSINESS
 
     The Company is engaged in a single business segment constituting the
development, manufacturing, and marketing of broadband transmission products,
network access products, and bandwidth optimization products for the
telecommunications industry. Regional Bell Operating Companies (RBOC),
independent telephone companies, and interexchange carriers are the primary
users of the Company's products. Sales to the RBOCs accounted for 41% of sales
in fiscal 1998, 39% of sales in fiscal 1997, and 37% of sales in fiscal 1996.
RBOC sales include sales to one RBOC of 36% of sales in fiscal 1998, 33% of
sales in fiscal 1997, and 31% of sales in fiscal 1996. In fiscal 1998, two
additional customers each represented 12% of sales. In fiscal 1997, two
additional customers each represented 11% and 10% of sales. In fiscal 1996, two
additional customers each represented 13% and 11% of sales.
 
     On June 4, 1998, the Company entered into a definitive agreement to merge
with a merger subsidiary of World Access, Inc. The transaction is subject to
stockholder and regulatory approval and is expected to be accounted for as a
purchase. The merger agreement, which was amended as of October 27, 1998,
provides that all shares of the Company's common stock will be converted into
shares of World Access common stock based on the average daily closing price of
World Access common stock as reported on the Nasdaq National Market System for a
predefined period prior to the effective time of the merger (the "Closing
Price"). If the Closing Price is more than $36.00, then each share of the
Company's common stock will be converted into 0.4722 shares of World Access
common stock. If the Closing Price is less than $29.00, then each share of the
Company's common stock will be converted into 0.5862 shares of World Access
common stock, provided that the nominal value of the consideration to be
received will be no less than $12.00 per share. If the Closing Price is between
$29.00 and $36.00, then the ratio will be the quotient of $17.00 divided by the
Closing Price (consideration value based upon the average of the high and low
trading prices of the World Access Common Stock on the day of the merger).
During fiscal 1998, the Company recorded sales of $1,442,000 to World Access.

     SFAS 109, "Accounting for Income Taxes", requires that a valuation reserve
be established if it is "more likely than not" that realization of the tax
benefits will not occur. In fiscal 1998 the valuation reserve increased by
$2,213,000 due primarily to the purchased research and development charge
related to the Jupiter acquisition (see Note 8) which was capitalized for income
tax purposes. This net increase also reflected the recognition of $650,000 of
net deferred tax assets, included in Other Current Assets, attributable to 1998
current income tax liabilities available to benefit future income tax losses, if
any.
 
     The Company had unused research and development and investment tax credit
carryforwards of $3,400,000 at August 30, 1998, which expire from fiscal years
1999 through 2013.

NOTE 5  LINE OF CREDIT
 
     The Company maintains a $20 million secured line of credit with Fleet Bank
which is available until December 31, 1998. At August 30, 1998, $351,100 was
reserved to support various guarantees relating to European Community customs
and duties in effect at that date. The Company had no borrowings against the
credit line at August 30, 1998.
 
NOTE 6  LEASE COMMITMENTS
 
     The Company leases a 216,000 square-foot manufacturing, research and
administration facility in Norwood, Massachusetts, from a limited partnership in
which the Company has a 50% interest. Neither the Company nor the other partners
have made or anticipate making any substantial capital contributions or advances
to the partnership. Under the partnership agreement, the Company, in addition to
its 50% interest, is entitled to a priority payment (which would proportionately
increase with an increase in the property value) out of the proceeds of any sale
or future refinancing of the property. The gross rent payable is $1.5 million
annually through January 31, 1999. For the remainder of the lease term ending
January 31, 2004, gross rent payable is $1.7 million annually.
 
     In June 1997, the Company entered into a sale-leaseback arrangement for
certain computer and other electronic equipment which provided cash of
approximately $2.6 million. The operating leases contained in the arrangement
cover periods from two to four years.
 
     The Company leases other facilities and certain equipment under
noncancelable operating leases expiring at various dates through 2005. The
Company is required to pay property taxes, insurance and normal maintenance
costs. Certain of the lease agreements provide for five-year renewal options,
and future lease payments could increase based on the Consumer Price Index.
 
     Minimum annual lease commitments under non-cancelable operating leases for
facilities and equipment as of August 30, 1998 are set forth in the following
table. Amounts relating to excess facilities included herein have been accrued
as discussed in Note 7:

</TABLE>
 
     The plan included the consolidation and move of manufacturing operations
from the Company's Fremont, California facility to its facility located in
Norwood, Massachusetts. During fiscal 1997, the relocation plan was accomplished
within original cost estimates. At August 30, 1998, the remaining fiscal 1993
and 1996 restructuring reserves for excess facility costs aggregated $1.5
million.
 
NOTE 8  ACQUISITIONS
 
     On January 26, 1998, the Company acquired substantially all of the assets
of Jupiter Technology, Inc., a privately held company engaged in the development
of ATM and frame relay access equipment. The transaction was accounted for using
the purchase method at a cost of $6.2 million, including issuance of 101,636
shares of common stock. The purchase price included $5.1 million which
represented the value of in-process technology that had not yet reached
technological feasibility and had no alternative use. This amount was expensed
during fiscal 1998. In addition, the purchase price included $1.1 million of
goodwill, which will be amortized over five years.
 
     In August 1998, the Company acquired a minority equity interest of Synaptyx
Corporation, a privately held communications network hardware company, for $1
million with an option to acquire 100% equity ownership. The $1 million
investment is accounted for under the cost method and included in Intangible and
Other Assets at August 30, 1998. In October 1998, the Company exercised its
option and acquired the remaining ownership for $9 million in equity securities
of the Company. The Synaptyx Acquisition Agreement provides for the Company to
issue an additional $4 million of common stock to be paid upon achievement of
certain revenue goals. The acquisition will be accounted for as a purchase.
 
NOTE 9  STOCK PLANS
 
     Under the Company's 1980 Stock Option Plan, the 1988 Non-Qualified Stock
Option Plan, and the 1990 Stock Option Plan (the Plans), officers, directors,
and key employees have been granted options to purchase shares of the Company's
common stock at a price equal to the market value at the date of grant. Options
normally become exercisable ratably over a 48 month period, commencing six
months from the date of grant, and expire after ten years. At August 30, 1998,
1,551,423 shares of common stock were reserved for issuance under the Plans.
 
     On May 20, 1997, the Board of Directors approved an amendment to the
Company's 1990 Stock Option Plan and reduced the exercise price of certain stock
options granted to employees between May 15, 1996 and May 13, 1997 at exercise
prices ranging from $11.50 to $20.875 per share. The exercise price was adjusted
to be equal to the current market price on that day. Stock options granted to
the Company's Board of Directors and to employees in conjunction with a general
option grant on March 5, 1997 were excluded from this action. Approximately
388,581 shares were reduced to the new exercise price of $9.625.

     On February 11, 1998, 6,000 restricted shares of the Company's common stock
were issued to certain key employees. Shares were awarded in the name of each of
the participants who have all the rights of other stockholders, subject to

     Under the Company's 1983 Employee Stock Purchase Plan, eligible employees
may purchase shares of common stock through payroll deductions (up to a maximum
of 10% of their salary) at a price equal to 85% of the lower of the stock's fair
market value at the beginning or at the end of each six month offering period.
During fiscal 1998, an additional 100,000 shares were authorized under the Plan.
There were 58,534 shares issuable under the Plan for fiscal 1998 of which 36,969
were outstanding at August 30, 1998. For fiscal 1997 and 1996 38,947 shares and
56,010 shares, respectively, were issued under the Plan. At August 30, 1998,
115,707 shares of common stock were reserved for issuance under the Plan.
 
     In October 1995, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standard 123 (SFAS 123), "Accounting for Stock-Based
Compensation". SFAS 123 requires that companies either recognize compensation
expense for grants of stock, stock options and other equity instruments based on
fair value, or provide pro forma disclosure of net income and earnings per share
in the notes to the financial statements. The Company adopted the
disclosure-only provisions of SFAS 123 in fiscal 1997 and has applied APB
Opinion No. 25 and related interpretations in accounting for its plans.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
NOTE 10.  EMPLOYEE BENEFIT PLAN
 
     The Company maintains a defined contribution savings plan under the
provisions of Internal Revenue Code Section 401(k). Under the terms of the Plan,
the Company contributes up to 3% of base pay to a fund which is held by a
trustee. All employees are eligible to participate in the Plan and are entitled,
upon termination or retirement, to receive their vested portion of the savings
fund assets. The unvested portion remains in the Plan and is used to reduce
future Plan expense. Total Plan expense was $391,000 in fiscal 1998, $468,000 in
fiscal 1997, and $547,000 in fiscal 1996.
 
NOTE 11.  STOCKHOLDER RIGHTS PLAN
 
     On February 19, 1997, the Board of Directors of Telco Systems, Inc. adopted
a Stockholder Rights Plan (the "Plan") and distributed one Right for each
outstanding share of the Company's Common Stock, par value $.01 per share. The
Rights were issued to holders of record of Common Stock outstanding on February
19, 1997. Each share of Common Stock issued after February 19, 1997 will also
include one Right subject to certain limitations. Each Right when it becomes
exercisable will initially entitle the registered holder to purchase from the
Company one one-hundredth (1/100th) of a share of Series A Participating
Cumulative Preferred Stock, par value $.01 per share ("Series A Preferred
Stock"), of the Company at a price of $50.00 (the "Exercise Price").
 
     Currently, the Rights are attached to the Company's common stock. These
Rights are not now exercisable and cannot be transferred separately. The Rights
become exercisable and separately transferable when the Board learns that any
person or group (other than Kopp Investment Advisors, Inc. and its affiliates or
associates (collectively "KIA")), has acquired 15% or more of the Company's
outstanding common stock or on such date as may be designated by the Board
following the announcement of a tender or exchange offer for outstanding shares
of common stock which could result in the offeror becoming the beneficial owner
of 15% or more of the Company's outstanding common stock. Under such
circumstances, holders of the Rights will be entitled to purchase, for the
Exercise Price, that number of hundredths of a share of Series A.
 
     Preferred Stock equivalent to the number of shares of the Company's common
stock (or under certain circumstances other equity securities) having a market
value of two times the Exercise Price. 15% holders (other than KIA), however,
are not entitled to exercise their Rights under such circumstances. As a result,
their voting and equity interests in the Company would be substantially diluted
should the rights ever be exercised.
 
     The Rights expire in February 2007, but may be redeemed earlier by the
Company in accordance with the provisions of the Rights Plan at a price of $.01
per Right.
 
     On June 4, 1998, the Plan was amended to allow for the merger with World
Access, Inc. without the Rights becoming exercisable.

               CONVERSION OF SECURITIES; EXCHANGE OF CERTIFICATES
 
     SECTION 3.01.  Conversion of Securities.  At the Effective Time, by virtue
of the Merger and without any action on the part of Merger Sub, the Company or
the holders of any of the following securities:
 
          (a) Each share of Company Common Stock (together with the right to
     purchase one-hundredth (1/100th) of a share of Company Preferred Stock (the
     "Rights")) issued and outstanding immediately prior to the Effective Time
     (other than any shares of Company Common Stock to be cancelled pursuant to
     Section 3.01(b) and, if applicable, any shares of Company Common Stock
     which are held by stockholders entitled to and validly exercising appraisal
     rights pursuant to Section 262 of the Delaware General Corporation Law
     ("Dissenting Stockholders")) and all rights in respect thereof shall
     forthwith cease to exist and shall be converted into and become
     exchangeable for the following (the "Merger Consideration"):
 
             (i) subject to subsection (ii) below, that number of shares of WAG
        Common Stock (the "Common Exchange Ratio") equal to the quotient of (A)
        $17.00 divided by (B) the Closing Date Market Price; provided, however,
        that (x) if the Closing Date Market Price is less than $29.00, then the
        Common Exchange Ratio shall be equal to .5862, and (y) if the Closing
        Date Market Price is more than $36.00, then the Common Exchange Ratio
        shall be equal to .4722;
 
             (ii) in lieu of the shares of WAG Common Stock provided by
        subsection (i) above, at the election of Parent upon irrevocable notice
        given to the Company in accordance with Section 10.02 hereof on the
        Determination Date, a pro rata portion of (A) the Cash Consideration
        Pool and (B) the Share Consideration Pool; and
 
             (iii) in the case of either subsection (i) or subsection (ii)
        above, if the aggregate Nominal Consideration is less than the Top-Up
        Amount, a pro rata portion of the Top-Up Consideration Pool.
 
          (b) Each share of Company Capital Stock held in the treasury of the
     Company and each share of Company Capital Stock owned by WAG or Parent (in
     each case, together with any Rights) or of the Company immediately prior to
     the Effective Time shall be cancelled and extinguished without any
     conversion thereof and no payment shall be made with respect thereto; and
 
          (c) Each share of common stock, par value $0.01 per share, of Merger
     Sub ("Merger Sub Common Stock") issued and outstanding immediately prior to
     the Effective Time shall be converted into and become one fully paid and
     nonassessable share of common stock, $0.01 par value per share, of the
     Surviving Corporation.
 
     SECTION 3.02  Exchange of Shares Other than Treasury Shares.  Subject to
the terms and conditions hereof, at or prior to the Effective Time, WAG shall
appoint an exchange agent reasonably acceptable to the Company to effect the
exchange of shares of Company Common Stock for the Merger Consideration, in
accordance with the provisions of this Article III (the "Exchange Agent"). From
time to time after the Effective Time, WAG shall deposit, or cause to be
deposited, certificates representing WAG Common Stock, the amount of the Cash
Consideration Pool and the amount of cash (if any) comprising a portion of the
Top-Up Consideration Pool for conversion of shares of Company Common Stock, in
accordance with the provisions of Section 3.01 (such certificates, together with
any dividends or distributions with respect thereto, and funds comprising the
Cash Consideration Pool and the Top-Up Consideration Pool (if any) being herein
referred to as the "Exchange Fund"). Commencing immediately after the Effective
Time and until the appointment of the Exchange Agent shall be terminated, each
holder of a certificate or certificates theretofore representing shares of
Company Common Stock may surrender the same to the Exchange Agent and, after the
appointment of the Exchange Agent shall be terminated, any such holder may
surrender any such certificate to WAG. Such holder shall be entitled upon such
surrender to receive in exchange therefor a certificate or certificates
representing the number of full shares of WAG Common Stock, the portion of the
Cash Consideration Pool and the portion of the Top-Up Consideration Pool into
which the shares of Company Common Stock theretofore represented by the
certificate or certificates so surrendered shall have been
 
                                       A-9
<PAGE>   330
 
converted in accordance with the provisions of Section 3.01, together with a
cash payment in lieu of fractional shares, if any, in accordance with Section
3.04, and the Merger Consideration shall be deemed to have been issued at the
Effective Time. Until so surrendered and exchanged, each outstanding certificate
which, prior to the Effective Time, represented issued and outstanding shares of
Company Common Stock shall be deemed for all corporate purposes of WAG, other
than the payment of dividends and other distributions, if any, to evidence
ownership of the number of full shares of WAG Common Stock, the portion of the
Cash Consideration Pool and the portion of the Top-Up Consideration Pool into
which the shares of Company Common Stock theretofore represented thereby shall
have been converted at the Effective Time in accordance with the provisions of
Section 3.01. Unless and until any such certificate theretofore representing
shares of Company Common Stock is so surrendered, no dividend or other
distribution, if any, payable to the holders of record of WAG Common Stock as of
any date subsequent to the Effective Time shall be paid to the holder of such
certificate in respect thereof. Upon the surrender of any such certificate
theretofore representing shares of Company Common Stock, however, the record
holder of the certificate or certificates representing shares of WAG Common
Stock issued in exchange therefor shall receive from the Exchange Agent or from
WAG, as the case may be, (i) payment of the amount of dividends and other
distributions, if any, which as of any date subsequent to the Effective Time and
until such surrender shall have become payable with respect to such number of
shares of WAG Common Stock ("Presurrender Dividends") and (ii) at the
appropriate payment date, the amount of dividends or other distributions with a
record date after the Effective Time but prior to such surrender and with a
payment date subsequent to such surrender payable with respect to such whole
shares of WAG Common Stock. No interest shall be payable with respect to the
payment of Presurrender Dividends upon the surrender of certificates theretofore
representing shares of Company Common Stock. After the appointment of the
Exchange Agent shall have been terminated, such holders of WAG Common Stock
which have not received payment of Presurrender Dividends shall look only to WAG
for payment thereof. Notwithstanding the foregoing provisions of this Section
3.02, risk of loss and title to such certificates representing shares of Company
Common Stock shall pass only upon proper delivery of such certificates to the
Exchange Agent, and neither the Exchange Agent nor any party hereto shall be
liable to a holder of shares of Company Capital Stock for any Merger
Consideration, or dividends or distributions thereon, delivered to a public
official pursuant to any applicable abandoned property, escheat or similar law
or to a transferee pursuant to Section 3.03. References in this Section 3.02 to
Company Common Stock shall be deemed to include the associated Rights.
 
     SECTION 3.03  Stock Transfer Books.  (a) At the Effective Time, each of the
stock transfer books of the Company with respect to shares of Company Common
Stock shall be closed, and there shall be no further registration of transfers
of shares of Company Common Stock thereafter on the records of any such stock
transfer books. In the event of a transfer of ownership of shares of Company
Common Stock that is not registered in the stock transfer records of the
Company, at the Effective Time, a certificate or certificates representing the
number of full shares of WAG Common Stock into which such shares of Company
Common Stock shall have been converted shall be issued to the transferee
together with a cash payment representing the portion of the Cash Consideration
Pool and the Top-Up Consideration Pool into which such shares shall have been
converted in accordance with Section 3.01 and cash in lieu of fractional shares,
if any, in accordance with Section 3.04, and a cash payment in the amount of
Presurrender Dividends, if any, in accordance with Section 3.02, if the
certificate or certificates representing such shares of Company Capital Stock is
or are surrendered as provided in Section 3.02, accompanied by all documents
required to evidence and effect such transfer and by evidence of payment of any
applicable stock transfer tax.
 
     (b) Notwithstanding anything to the contrary herein, certificates
surrendered for exchange by any person constituting a Rule 145 Affiliate of the
Company shall not be exchanged until Parent shall have received from such person
an executed Company Affiliate Agreement, as provided in Section 7.03.
 
     SECTION 3.04.  No Fractional Share Certificates.  Unless WAG otherwise
determines, no scrip or fractional share certificates for WAG Common Stock shall
be issued upon the surrender for exchange of certificates evidencing shares of
Company Capital Stock, and an outstanding fractional share interest shall not
entitle the owner thereof to vote, to receive dividends or to any rights of a
stockholder of WAG or of the Surviving Corporation with respect to such
fractional share interest. In lieu of fractional shares, each holder of
 
                                      A-10
<PAGE>   331
 
shares of Company Common Stock who, except for the provisions of this Section
3.04, would be entitled to receive a fractional share of WAG Common Stock shall,
upon surrender of the certificate or certificates representing shares of Company
Common Stock, be entitled to receive an amount in cash (rounded to the nearest
whole cent), without interest, equal to the product obtained by multiplying (a)
the fractional share interest to which such holder would otherwise be entitled
(after taking into account all shares of Company Capital Stock held at the
Effective Time by such holder) by (b) the closing price for a share of WAG
Common Stock reported on Nasdaq on the first business day immediately prior to
the Effective Time. At or prior to the Effective Time, Parent shall pay to the
Exchange Agent an amount in cash (the "Cash Deposit") sufficient for the
Exchange Agent to pay each holder of Company Common Stock the amount of cash in
lieu of fractional shares to which such holder is entitled pursuant to this
Section 3.04. As soon as practicable after the determination of the amount of
cash, if any, to be paid to holders of Company Common Stock with respect to any
fractional share interests, the Exchange Agent shall make available such
amounts, net of any required withholding, to such holders of Company Common
Stock, subject to and in accordance with the terms of Section 3.02. In no event
shall either (i) the total cash consideration paid to holders of Company Common
Stock in lieu of fractional shares exceed one percent (1%) of the value of the
total consideration issued to holders of Company Common Stock in exchange for
their Company Capital Stock or (ii) any record holder of Company Common Stock,
directly or indirectly, receive cash in an amount equal to or greater than the
value of one full share of WAG Company Stock.
 
     SECTION 3.05.  Options to Purchase Company Common Stock.  At the Effective
Time, each option granted by the Company to purchase shares of Company Common
Stock (each, a "Company Stock Option") which is outstanding and unexercised
immediately prior to the Effective Time shall be assumed by WAG and converted
into an option to purchase shares of WAG Common Stock in such number and at such
exercise price as provided below and otherwise having the same terms and
conditions as in effect immediately prior to the Effective Time (except to the
extent that such terms, conditions and restrictions may be altered in accordance
with their terms as a result of the Merger, including vesting as such shall
(except as provided in Section 6.01(b)) be accelerated at the Effective Time
pursuant to the terms of such Company Stock Options):
 
          (a) the number of shares of WAG Common Stock to be subject to the new
     option shall be equal to the product of (i) the number of shares of Company
     Common Stock subject to the original option and (ii) the Common Exchange
     Ratio; provided, however, that if the value of the Top-Up Consideration
     Pool is greater than zero, the Common Exchange Ratio for purposes of this
     Section 3.05(a) shall be equal to the quotient of $12.00 divided by the
     Closing Date Market Price;
 
          (b) the exercise price per share of Parent Common Stock under the new
     option shall be equal to the quotient of (i) the exercise price per share
     of Company Common Stock under the original option divided by (ii) the
     Common Exchange Ratio; provided, however, that if the value of the Top-Up
     Consideration Pool is greater than zero, then the Common Exchange Ratio for
     purposes of this Section 3.05(b) shall be equal to the quotient of $12.00
     divided by the Closing Date Market Price; and
 
          (c) upon each exercise of options by a holder thereof, the aggregate
     number of shares of WAG Common Stock deliverable upon such exercise shall
     be rounded, if necessary, to the nearest whole share and the aggregate
     exercise price shall be rounded up, if necessary, to the nearest cent.
 
The adjustments provided herein with respect to any options which are "incentive
stock options" (as defined in Section 422 of the Code) shall be effected in a
manner consistent with the requirements of Section 424(a) of the Code.
 
     SECTION 3.06.  Certain Adjustments.  If between the date of this Agreement
and the Effective Time, the outstanding shares of Company Capital Stock or WAG
Common Stock shall be changed into a different number of shares by reason of any
reclassification, recapitalization, split-up, combination or exchange of shares,
or any dividend payable in stock or other securities shall be declared thereon
with a record date within such period, then the exchange ratios established
pursuant to the provisions of Section 3.01 shall be adjusted accordingly to
provide to the holders of Company Capital Stock the same economic effect as
contemplated by this Agreement prior to such reclassification, recapitalization,
split-up, combination,
 
                                      A-11
<PAGE>   332
 
exchange, dividend or increase. In the event the Holding Company Reorganization
is consummated prior to the Effective Time, all references in this Article III
to WAG and to WAG Common Stock shall be deemed to be references to Parent and
Parent Common Stock, respectively.
 
     SECTION 3.07.  Undistributed Amounts.  Any portion of the Exchange Fund or
the Cash Deposit which remains undistributed for six months after the Effective
Time shall be delivered to WAG, and any holder of Company Common Stock who has
not theretofore complied with the provisions of this Article III shall
thereafter look only to WAG for satisfaction of their claims for WAG Common
Stock or any cash in lieu of fractional shares of WAG Common Stock and any
Presurrender Dividends.
 
     SECTION 3.08.  Dissenters' Rights.  Notwithstanding anything in this
Agreement to the contrary, any issued and outstanding shares of Company Common
Stock held by a Dissenting Stockholder shall not be converted as described in
Section 3.01(a) but, as of the Effective Time, shall no longer be outstanding
and shall automatically be canceled and retired and shall cease to exist and
shall become the right to receive such consideration as may be determined to be
due to such Dissenting Stockholder pursuant to the laws of the State of
Delaware; provided, however, that the shares of Company Common Stock outstanding
immediately prior to the Effective Time and held by a Dissenting Stockholder who
shall, after the Effective Time withdraw his or her demand for appraisal or lose
his or her right of appraisal, in either case pursuant to the Delaware General
Corporation Law, shall be deemed to be converted as of the Effective Time into
the right to receive the Merger Consideration. The Company shall give Parent (i)
prompt notice of any written demands for appraisal of shares of Company Common
Stock received by the Company and (ii) the opportunity to participate in all
negotiations and proceedings with respect to any such demands.
 
                                   ARTICLE IV

good standing (to the extent applicable) under the laws of the jurisdiction of
its incorporation or organization, as the case may be, and has the requisite
corporate power and authority and all necessary governmental approvals to own,
lease and operate its properties and to carry on its business as it is now being
conducted, except where the failure to be so organized, existing or in good
standing or to have such power, authority and governmental approvals would not
reasonably be expected to have, individually or in the aggregate, a Company
Material Adverse Effect. The Company and each Company Subsidiary is duly
qualified or licensed to do business, and is in good standing (to the extent
applicable), in each jurisdiction where the character of the properties owned,
leased or operated by it or the nature of its business makes such qualification
or licensing necessary, except for such failures to be so qualified or licensed
and in good standing that would not reasonably be expected to have, individually
or in the aggregate, a Company Material Adverse Effect.
 
     (b) Section 4.01 of the Company Disclosure Schedule sets forth, as of the
date of this Agreement, a true and complete list of each Company Subsidiary,
together with (i) the jurisdiction of incorporation or organization of each
Company Subsidiary and the percentage of each Company Subsidiary's outstanding

Except as set forth in Section 4.01 of the Company Disclosure Schedule, neither
the Company nor any Company Subsidiary owns an equity interest in any
partnership or joint venture arrangement or other business entity that is
material to the financial condition, results of operations, business or
prospects of the Company and the Company Subsidiaries, taken as a whole.
 
     SECTION 4.02.  Certificate of Incorporation and Bylaws.  The copies of the
Company's certificate of incorporation and bylaws that are incorporated by
reference as exhibits to the Company's Annual Report on Form 10-K for the fiscal

                                      A-12
<PAGE>   333
 
correct copies thereof. Such certificate of incorporation and bylaws are in full
force and effect. The Company is not in violation of any of the provisions of
its certificate of incorporation or bylaws.
 
     SECTION 4.03.  Capitalization.  The authorized capital stock of the Company
consists of 25,000,000 shares of Company Common Stock, 1,000,000 shares of which

nonassessable, (ii) no shares of Company Common Stock are held in the treasury
of the Company, (iii) no shares of Company Common Stock are held by the Company

(collectively, the "Company Stock Purchase Plans"), (vi) 200,000 shares of
Company Preferred Stock are reserved for issuance pursuant to the Rights; and
(vii) no shares of Company Junior Common Stock are issued and outstanding.
Except for shares of Company Common Stock issuable pursuant to the Company Stock
Plans or pursuant to agreements or arrangements described in Section 4.03 of the
Company Disclosure Schedule or in the Company Reports and other than the Rights,
there are no options, warrants or other rights, agreements, arrangements or
commitments of any character to which the Company is a party or by which the
Company is bound relating to the issued or unissued capital stock of the Company
or any Company Subsidiary or obligating the Company or any Company Subsidiary to
issue or sell any shares of capital stock of, or other equity interests in, the
Company or any Company Subsidiary. Section 4.03 of the Company Disclosure

clear of all security interests, liens, claims, pledges, options, rights of
first refusal, agreements, limitations on the Company's or such other Company
Subsidiary's voting rights, charges and other encumbrances of any nature
whatsoever, except where the failure to own such shares free and clear would not
reasonably be expected to have, individually or in the aggregate, a Company
Material Adverse Effect. Except as set forth in Section 4.03 of the Company
Disclosure Schedule, there are no outstanding contractual obligations of the
Company or any Company Subsidiary to provide funds to, or make any material
investment (in the form of a loan, capital contribution or otherwise) in, any
Company Subsidiary or any other person. Prior to the execution and delivery of
this Agreement, the Company has entered into Amendment No. 1 to that certain
Rights Agreement dated as of February 19, 1997 between the Company and The First
National Bank of Boston, a national banking association, as Rights Agent (the

     SECTION 4.04.  Authority Relative to this Agreement.  The Company has all
necessary corporate power and authority to execute and deliver this Agreement,
to perform its obligations hereunder and to consummate the transactions
contemplated hereby. The execution and delivery of this Agreement by the Company
and the consummation by the Company of the transactions contemplated hereby have
been duly and validly authorized by all necessary corporate action, and no other
corporate proceedings on the part of the Company are necessary to authorize this
Agreement or to consummate such transactions (other than the approval of this
Agreement and the Merger by the holders of a majority of the outstanding shares
of Company Common Stock entitled to vote with respect thereto at the Company
Stockholders' Meeting and the filing and recordation of the Certificate of
Merger as required by the Delaware General Corporation Law). This
 
                                      A-13
<PAGE>   334
 
Agreement has been duly executed and delivered by the Company and, assuming the
due authorization, execution and delivery by the other parties hereto,
constitutes the legal, valid and binding obligation of the Company, enforceable
against the Company in accordance with its terms.
 
     SECTION 4.05.  No Conflict; Required Filings and Consents.  (a) The
execution and delivery of this Agreement by the Company do not, and the
performance by the Company of its obligations hereunder and the consummation of
the Merger will not, (i) conflict with or violate any provision of the
certificate of incorporation or bylaws of the Company or any equivalent
organizational documents of any Company Subsidiary, (ii) assuming that all
consents, approvals, authorizations and permits described in Section 4.05(b)
have been obtained and all filings and notifications described in Section
4.05(b) have been made, conflict with or violate any Law applicable to the
Company or any Company Subsidiary or by which any property or asset of the
Company or any Company Subsidiary is bound or affected or (iii) except as set
forth in Section 4.05(a) of the Company Disclosure Schedule, result in any
breach of or constitute a default (or an event which with the giving of notice
or lapse of time or both would reasonably be expected to become a default)
under, or give to others any right of termination, amendment, acceleration or
cancellation of, or result in the creation of a lien or other encumbrance on any
property or asset of the Company or any Company Subsidiary pursuant to, any
note, bond, mortgage, indenture, contract, agreement, lease, license, permit,
franchise or other instrument or obligation, except, with respect to clauses
(ii) and (iii), for any such conflicts, violations, breaches, defaults or other
occurrences which would not reasonably be expected, individually or in the
aggregate, (A) to have a Company Material Adverse Effect or (B) to prevent or
materially delay the performance by the Company of its obligations pursuant to
this Agreement or the consummation of the Merger.
 
     (b) The execution and delivery of this Agreement by the Company do not, and
the performance by the Company of its obligations hereunder and the consummation
of the Merger will not, require any consent, approval, authorization or permit
of, or filing by the Company with or notification by the Company to, any
Governmental Entity, except (i) pursuant to applicable requirements of the
Exchange Act, the Securities Act, Blue Sky Laws, the rules and regulations of
Nasdaq, state takeover laws, the premerger notification requirements of the HSR
Act, if any, the filing and recordation of the Certificate of Merger as required
by the Delaware General Corporation Law, and as set forth in Section 4.05(b) of
the Company Disclosure Schedule, and (ii) where failure to obtain such consents,
approvals, authorizations or permits, or to make such filings or notifications,
would not reasonably be expected, individually or in the aggregate, (A) to have
a Company Material Adverse Effect or (B) to prevent or materially delay the
performance by the Company of its obligations pursuant to this Agreement or the
consummation of the Merger.
 
     SECTION 4.06.  Permits; Compliance with Laws.  The Company and the Company
Subsidiaries are in possession of all franchises, grants, authorizations,
licenses, establishment registrations, product listings, permits, easements,
variances, exceptions, consents, certificates, identification and registration
numbers, approvals and orders of any Governmental Entity necessary for the
Company or any Company Subsidiary to own, lease and operate its properties or to
produce, store, distribute and market its products or otherwise to carry on its
business as it is now being conducted (collectively, the "Company Permits"),
except where the failure to have, or the suspension or cancellation of, any of
the Company Permits would not reasonably be expected to have, individually or in
the aggregate, a Company Material Adverse Effect, and, as of the date of this
Agreement, no suspension or cancellation of any of the Company Permits is
pending or, to the knowledge of the Company, threatened, except where the
failure to have, or the suspension or cancellation of, any of the Company
Permits would not reasonably be expected to have, individually or in the
aggregate, a Company Material Adverse Effect. Neither the Company nor any
Company Subsidiary is in conflict with, or in default or violation of, (i) any
Law applicable to the Company or any Company Subsidiary or by which any property
or asset of the Company or any Company Subsidiary is bound or affected or (ii)
any Company Permits, except in the case of clauses (i) and (ii) for any such
conflicts, defaults or violations that would not reasonably be expected to have,
individually or in the aggregate, a Company Material Adverse Effect. Except as

          REPRESENTATIONS AND WARRANTIES OF WAG, PARENT AND MERGER SUB
 
     WAG, Parent and Merger Sub hereby jointly and severally represent and
warrant to the Company that:
 
     SECTION 5.01.  Organization and Qualification; Subsidiaries.  WAG, Parent,
Merger Sub and each other subsidiary of Parent or WAG (the "Parent
Subsidiaries") has been duly organized and is validly existing

jurisdiction of its incorporation or organization, as the case may be, and has
the requisite corporate power and authority and all necessary governmental
approvals to own, lease and operate its properties and to carry on its business
as it is now being conducted, except where the failure to be so organized,
existing or in good standing or to have such power, authority and governmental
approvals would not reasonably be expected to have, individually or in the
aggregate, a Parent Material Adverse Effect. WAG, Parent, Merger Sub and each
other Parent Subsidiary is duly qualified or licensed to do business, and is in
good standing (to the extent applicable), in each jurisdiction where the
character of the properties owned, leased or operated by it or the nature of its
business makes such qualification or licensing necessary, except for such
failures to be so qualified or licensed and in good standing that would not
reasonably be expected to have, individually or in the aggregate, a Parent
Material Adverse Effect.
 
     (b) Section 5.01 of the Parent Disclosure Schedule sets forth, as of the
date of this Agreement, a true and complete list of each Parent Subsidiary,
together with (i) the jurisdiction of incorporation or organization of each
Parent Subsidiary and the percentage of each Parent Subsidiary's outstanding
capital stock or other equity interests owned by Parent or another Parent
Subsidiary and (ii) an indication of whether each Parent Subsidiary is a
"Significant Subsidiary" as defined in Regulation S-X under the Exchange Act.
Except as set forth in Section 5.01 of the Parent Disclosure Schedule, neither
Parent nor any Parent Subsidiary owns an equity interest in any partnership or
joint venture arrangement or other business entity that is material to the
financial condition, results of operations, business or prospects of Parent and
the Parent Subsidiaries, taken as a whole.
 
     SECTION 5.02.  Certificate of Incorporation and Bylaws.  The copies of
WAG's certificate of incorporation and bylaws that are incorporated by reference
as exhibits to WAG's Annual Report on Form 10-K for the fiscal year ended
December 31, 1997 (the "Parent 1997 10-K") are true, complete and correct copies
thereof. Parent has heretofore furnished the Company with true, complete and
correct copies of the certificate of incorporation and bylaws of each of Parent
and Merger Sub. Such certificates and bylaws are in full force and effect.

others any right of termination, amendment, acceleration or cancellation of, or
result in the creation of a lien or other encumbrance on any property or asset
of WAG, Parent, Merger Sub or any other Parent Subsidiary pursuant to, any note,
bond, mortgage, indenture, contract, agreement, lease, license, permit,

     (b) The execution and delivery of this Agreement by WAG, Parent and Merger

Parent or Merger Sub with or notification by WAG, Parent or Merger Sub to, any
Governmental Entity, except (i) pursuant to applicable requirements of the
Exchange Act, the Securities Act, Blue Sky Laws, the rules and regulations of
Nasdaq, state takeover laws, the premerger notification requirements of the HSR
Act, if any, and the filing and recordation of the Certificate of Merger as

Governmental Entity necessary for WAG, Parent, Merger Sub or any other Parent
Subsidiary to own, lease and operate its properties or to store, distribute and
market its products or otherwise to carry on its business as it is now being
conducted (collectively, the "Parent Permits"), except where the failure to
have, or the suspension or cancellation of, any of the Parent Permits would not
reasonably be expected to have, individually or in the aggregate, a Parent
Material Adverse Effect, and, as of the date of this Agreement, no suspension or
cancellation of any of the Parent Permits is pending or, to the knowledge of
Parent or WAG, threatened, except where the failure to have, or the suspension
or cancellation of, any of the Parent Permits would not reasonably be expected
to have, individually or in the aggregate, a Parent Material Adverse Effect.
None of WAG, Parent, Merger Sub or any other Parent Subsidiary is in conflict
with, or in default or violation of, (i) any Law applicable to WAG, Parent,
Merger Sub or any other Parent Subsidiary or by which any property or asset of

31, 1997, neither WAG or Parent nor any Parent Subsidiary has received from any
Governmental Entity any written notification with respect to possible conflicts,

circumstances under which they were made, not misleading. Each form, report,
statement and document referred to in clause (b) of this paragraph was prepared
in all material respects in accordance with the requirements of applicable Law.
Except as disclosed in Section 5.07(a) of the Parent Disclosure Schedule, no

Directors of Parent or WAG, Parent or WAG, as applicable, shall use all
reasonable efforts to solicit from its stockholders proxies in favor of the
issuance of Parent Common Stock or WAG Common Stock, as the case may be, in the
Merger and the Capital Increase contemplated hereby pursuant to the Proxy
Statement and shall take all other action necessary or advisable to secure the
vote of stockholders required by the Delaware General Corporation Law or
applicable stock exchange requirements to obtain such approval, if required.
Each of the parties hereto shall, subject to the fiduciary duties of its Board
of Directors, take all other action necessary or, in the opinion of the other
parties hereto, advisable to promptly and expeditiously secure any vote or
consent of stockholders required by applicable Law and such party's certificate
of incorporation, as the case may be, and bylaws to effect the Merger.

Effective Time, the Company shall deliver to Parent a list of names and
addresses of each person who was, in the Company's reasonable judgment, at the
record date for the Company Stockholders' Meeting, a Rule 145 Affiliate of the
Company. The Company shall provide Parent such information and documents as
Parent shall reasonably request for purposes of reviewing such list. The Company
shall use all reasonable efforts to deliver or cause to be delivered to Parent,
prior to the Effective Time, an affiliate agreement in the form attached hereto
as Exhibit 7.03 (each, a "Company Affiliate Agreement"), executed by each of the
Rule 145 Affiliates of the Company identified in the above-referenced list. The
foregoing notwithstanding, Parent shall be entitled to place the legend only as

Company or (ii) any person Parent reasonably identifies (by written notice to
the Company) as being a person who may be deemed an "affiliate" within the
meaning of rule 145(c) or (d) promulgated under the Securities Act, and to issue
appropriate stop transfer instructions to the transfer agent for such Parent
Common Stock, consistent with the terms of the Company Affiliate Agreement,
regardless of whether such person has executed a Company Affiliate Agreement and

the Company Disclosure Schedule.
 
     SECTION 7.04.  Directors' and Officers' Indemnification.  (a) The
certificate of incorporation and bylaws of the Surviving Corporation shall
contain the provisions with respect to indemnification that are set forth, as of
the date of this Agreement, in the certificate of incorporation and bylaws of
the Company, which provisions shall not be amended, repealed or otherwise
modified for a period of six years from the Effective Time in any manner that
would affect adversely the rights thereunder of individuals who at or at any
time prior to the Effective Time were directors, officers, employees,
fiduciaries or agents of the Company.
 
     (b) From and after the Effective Time, Parent, WAG and the Surviving
Corporation shall indemnify and hold harmless each present and former director
and officer of the Company (the "Indemnified Parties"), against any costs or
expenses (including reasonable attorneys' fees), judgments, fines, losses,
claims, damages or liabilities (collectively, "Costs") incurred in connection
with any claim, action, suit, proceeding or investigation, whether civil,
criminal, administrative or investigative, arising out of or pertaining to
matters existing or occurring at or prior to the Effective Time, whether
asserted or claimed prior to, at or after the Effective Time, to the fullest
extent that the Company would have been permitted under Delaware law and under
its charter documents as in effect on the date hereof to indemnify such
Indemnified Parties, and WAG and Parent shall also advance expenses as incurred
to the fullest extent permitted under Delaware law upon receipt from the
applicable Indemnified Party to whom expenses are to be advanced of an
undertaking to repay such advances if it is ultimately determined such person is
not entitled to indemnification.
 
     (c) In the event that either of the Surviving Corporation, Parent or WAG or
any of its successors or assigns (i) consolidates with or merges into any other
person and is not the continuing or surviving corporation or entity of such
consolidation or merger or (ii) transfers or conveys all or substantially all of
its properties and assets to any person, then, and in each such case, proper
provision will be made so that the successors and assigns of Parent, WAG or the
Surviving Corporation, as applicable, will assume the obligations thereof set
forth in this Section 7.04.
 
                                      A-35
<PAGE>   356
 
     (d) The provisions of this Section 7.04 (i) are intended to be for the
benefit of, and will be enforceable by, each Indemnified Party, his or her heirs
and his or her representatives and (ii) are in addition to, and not in
substitution for, any other rights to indemnification or contribution that any
such person may have by contract or otherwise.
 
     (e) For six years after the Effective Time, WAG or the Surviving
Corporation shall maintain in effect the Company's current directors' and
officers' liability insurance covering acts or omissions occurring prior to the
Effective Time with respect to those persons who are currently covered by the
Company's directors' and officers' liability insurance policy on terms with
respect to such coverage and amount no less favorable to the Company's directors
and officers currently covered by such insurance than those of such policy in
effect on the date hereof, provided that WAG may substitute therefor policies of
WAG or the Parent Subsidiaries containing terms with respect to coverage and
amount no less favorable to such directors or officers; provided, further, that
in no event shall WAG or the Surviving Corporation be required to pay aggregate
premiums for insurance under this Section 7.04(e) in excess of 150% of the
aggregate premiums paid by the Company in 1997 on an annualized basis for such
purpose; and, provided further, that if WAG or the Surviving Corporation is
unable to obtain the amount of insurance required by this Section 7.04(e) for
such aggregate premium, then WAG or the Surviving Corporation shall obtain as
much insurance as can be obtained for an annual premium equal to 150% of the
1997 premium.
 
     (f) WAG shall cause the Surviving Corporation or any successor thereto to
comply with its obligations under this Section 7.04.
 
     SECTION 7.05.  No Shelf Registration.  Parent shall not be required to

purpose of permitting resale of the shares of Parent Common Stock received
pursuant hereto by the persons who may be deemed to be "affiliates" of the
Company or Parent within the meaning of rule 145 promulgated under the
Securities Act.
 
     SECTION 7.06.  Public Announcements.  Parent and the Company shall consult
with each other before issuing any press release or otherwise making any public
statements with respect to this Agreement or the Merger and shall not issue any
such press release or make any such public statement without the prior written
approval of the other, except to the extent required by applicable Law or the
requirements of the rules and regulations of Nasdaq, in which case the issuing
party shall use all reasonable efforts to consult with the other party before
issuing any such release or making any such public statement.
 
     SECTION 7.07.  Nasdaq Listing.  Each of the parties hereto shall use all
reasonable efforts to obtain, prior to the Effective Time, the approval for
including in Nasdaq, effective upon official notice of issuance, of the shares
of WAG Common Stock or Parent Common Stock, as the case may be, into which the
shares of Company Capital Stock will be converted pursuant to Article III and
the shares of WAG Common Stock or Parent Common Stock, as the case may be, which
will be issuable upon exercise of Company Stock Options pursuant to Section
3.05.
 
     SECTION 7.08.  Blue Sky.  Each of the parties hereto shall use all
reasonable efforts to obtain prior to the Effective Time all necessary blue sky
permits and approvals required under Blue Sky Laws to permit the distribution of
the shares of WAG Common Stock or Parent Common Stock, as the case may be, to be
issued in accordance with the provisions of this Agreement.
 
     SECTION 7.09.  Company Stock Options.  (a) At the Effective Time, Parent,
in the case the Holding Company Reorganization shall have been consummated, or
WAG, in the case the Holding Company Reorganization shall not have been
consummated, shall assume, by virtue of this Agreement and without any further
action on the part of the Company, all of the Company's obligations with respect
to each outstanding Company Stock Option, whether previously vested or unvested.
Unless otherwise elected by Parent prior to the Effective Time, Parent or WAG
shall make such assumption in such manner that Parent or WAG (i) is a
corporation "assuming a stock option in a transaction to which Section 424(a)
applies" within the meaning of Section 424 of the Code or (ii) to the extent
that Section 424 of the Code does not apply to such Company Stock Option, would
be such a corporation were Section 424 of the Code applicable to such Company
Stock Option; and, if not so otherwise elected, after the Effective Time, all
references to the Company in the
 
                                      A-36
<PAGE>   357
 
Company Stock Plans and the applicable Company Stock Option agreements shall be
deemed to refer to WAG, prior to the Holding Company Reorganization, or Parent,
following the Holding Company Reorganization, which shall have assumed the
Company Stock Plans as of the Effective Time by virtue of this Agreement and
without any further action on the part of the Company, Parent or WAG. Each
Company Stock Option so assumed under this Agreement shall continue to have, and
be subject to, the same terms and conditions set forth in the applicable Company
Stock Plan and the applicable Company Stock Option as in effect immediately
prior to the Effective Time, except as otherwise provided in Section 3.05.
Parent shall use all reasonable efforts to ensure that Company Stock Options
intended to qualify as incentive stock options under Section 422 of the Code
prior to the Effective Time continue to so qualify after the Effective Time.
 
     (b) With respect to the Company Stock Plans, WAG or Parent, as the case may
be, shall take all corporate action necessary or appropriate to (i) reserve for
issuance the number of shares that will be subject to Company Stock Options
referred to in this Section 7.09 and (ii), no later than the Effective Time,
file a registration statement on Form S-8 (or any successor or other appropriate
form) with respect to the shares of WAG Common Stock or Parent Common Stock, as
the case may be, subject to such plan to the extent such registration statement
is required under applicable law in order for such shares of common stock to be
sold without restriction, and WAG and Parent shall use its best efforts to
maintain the effectiveness of such registration statement (and maintain the
current status of the prospectuses contained therein) for so long as such
benefits and grants remain payable and such options under such plans remain
outstanding.
 
     SECTION 7.10.  Tax Treatment.  Each of Parent, WAG and the Company shall
use best efforts to cause the Merger to qualify as a reorganization under the
provisions of Section 368 of the Code and to obtain the opinions of counsel
referred to in Sections 8.02(c) and 8.03(c). In addition, following the
Effective Time, each of WAG, Parent and the Surviving Corporation agree not to
take any action that would cause the Merger to fail to so qualify.
 
     SECTION 7.11.  Obligations of Parent and WAG.  Prior to consummation of the
Holding Company Reorganization, WAG will take all action necessary to cause
Parent and Merger Sub to perform their respective obligations under this
Agreement and to consummate the Merger on the terms and conditions set forth
herein. Following consummation of the Holding Company Reorganization, Parent
will take all action necessary to cause WAG and Merger Sub to perform their
respective obligations under this Agreement and to consummate the Merger on the
terms and conditions set forth herein.
 
     SECTION 7.12.  Company Employees.  (a) Individuals who are employed by the
Company or the Company Subsidiaries as of the Effective Time shall remain
employees of the Surviving Corporation or the Surviving Corporation's
subsidiaries, as applicable, immediately following the Effective Time (each such
employee, an "Affected Employee"). For a period of one year immediately
following the Effective Time, the annual cash compensation for each Affected
Employee shall not be reduced without such Affected Employee's consent and the
insurance coverage, benefits and vacation and 401(k) participation benefits
provided to Affected Employees shall be, in the aggregate, not less favorable
than those provided to such employees immediately prior to the Effective Time.
Following the Effective Time, for purposes of determining eligibility, vesting
and level of benefits under all employee benefit plans (but not for pension
benefit accrual purposes) and, if applicable, for purposes of satisfying any
waiting periods concerning "preexisting conditions" and the satisfaction of any
"copayment" or deductible requirements, service with the Company or a Company
Subsidiary or any predecessor thereto prior to the Effective Time shall be
treated, to the extent permitted by law, as service with an "employer" to the
same extent as if such persons had been employees of WAG, Parent or a Parent
Subsidiary, and provided further that this Section 7.12(a) shall not be
construed to limit the ability of the applicable employer to terminate the
employment of any Affected Employee or to review employee benefits programs from
time to time and to make such changes as they deem appropriate.
 
     (b) WAG and the Parent agree to honor, or to cause the appropriate
subsidiary to honor, in accordance with their terms all Company Benefit Plans;
provided, however, that the foregoing shall not prevent any party from amending
or terminating any such plan, contact, agreement, arrangement or understanding
in accordance with its terms.
 
                                      A-37
<PAGE>   358
 
     (c) For the purpose of all Company Benefit Plans which include the term
"change in control", WAG and Parent acknowledge that the Merger constitutes a
"change in control" for all purposes pursuant to any such Company Benefit Plans.
In addition, WAG and Parent acknowledge that, with respect to the Senior
Termination Benefits Agreements listed in Schedule 7.12(c) (the "Listed
Agreements"), in light of WAG's and Parent's plans relating to management
assignments and responsibilities with respect to the business of the Company
from and after the Effective Time, each employee who is a party to any such
contract may, following consummation of the Merger, terminate employment
thereunder and, upon such termination, be entitled to termination payments and
benefits described therein.
 
     SECTION 7.13.  Board of Directors of Parent and WAG.  Immediately prior to
the Effective Time, the boards of directors of Parent and WAG shall take all
action necessary to cause an individual mutually acceptable to the boards of
directors of the Company, on the one hand, and the boards of directors of Parent
and WAG, on the other hand, to be elected to fill the vacancy on the boards of
directors of Parent and WAG at the Effective Time; provided, however, that if
the Holding Company Reorganization shall have been consummated prior to the
Effective Time, then the individual selected pursuant to the foregoing provision
shall not be elected to serve as a director of WAG.

     prohibiting its consummation;
 
          (d) any waiting period (and any extension thereof) applicable to the
     consummation of the Merger under the HSR Act shall have expired or be

     is materially adverse to the business, assets (including intangible
     assets), liabilities (contingent or otherwise), condition (financial or
     otherwise) or results of operations of WAG, Parent and the Parent
     Subsidiaries, taken as a whole; and

     have occurred on or before December 31, 1998; provided, however, that in
     the event that the Effective Time has not occurred by such time solely due

     Parent or its stockholders or shall have resolved to do so, or (ii) the
     board of directors of the Company shall have recommended to the

     or agreement on the part of the Company set forth in this Agreement, or if
     any representation or warranty of the Company shall have become untrue,
     incomplete or incorrect, in either case such that the conditions set forth
     in Section 8.03 would not be satisfied (a "Terminating Company Breach");
     provided, however, that if such Terminating Company Breach is curable by
     the Company through the exercise of its reasonable efforts within 30 days
     and for so long as the Company continues to exercise such reasonable
     efforts, Parent may not terminate this Agreement under this Section
     9.01(g); and provided further that the immediately preceding proviso shall
     not in any event be deemed to extend any date set forth in paragraph (b) of

     Terminating Parent Breach is curable by Parent through the exercise of its
     reasonable efforts within 30 days and for so long as Parent continues to
     exercise such reasonable efforts, the Company may not terminate this
     Agreement under this Section 9.01(h); and provided further that the
     preceding proviso shall not in any event be deemed to extend any date set
     forth in paragraph (b) of this Section 9.01; or
 
          (i) by the Company at any time prior to the Company Stockholders'
     Meeting, if, as a result of a Superior Proposal by a third party, the Board
     of Directors of the Company determines in good faith after consultation
     with outside counsel that it is highly probable that the Board of Directors
     would violate its fiduciary duties under applicable law if it failed to
     accept the Superior Proposal.
 
     SECTION 9.02.  Effect of Termination.  Except as provided in Section 9.05,
in the event of termination of this Agreement pursuant to Section 9.01, this
Agreement shall forthwith become void, there shall be no liability under this
Agreement on the part of any party hereto or any of its affiliates or any of its
or their officers or directors, and all rights and obligations of each party
hereto shall cease, subject to the remedies of the parties hereto set forth in
Section 9.05(b); provided, however, that nothing herein shall relieve any party
hereto from liability for the willful or intentional breach of any of its
representations and warranties or the willful or intentional breach of any of
its covenants or agreements set forth in this Agreement.
 
     SECTION 9.03.  Amendment.  This Agreement may be amended by the parties
hereto by action taken by or on behalf of their respective boards of directors
at any time prior to the Effective Time; provided, however, that, after the
approval of this Agreement by the stockholders of the Company, WAG or Parent, as
the case may be, no amendment may be made, except such amendments that have
received the requisite stockholder approval and such amendments as are permitted
to be made without stockholder approval under the Delaware General Corporation
Law, as applicable. This Agreement may not be amended except by an instrument in
writing signed by the parties hereto.
 
     SECTION 9.04.  Waiver.  At any time prior to the Effective Time, any party
hereto may (a) extend the time for or waive compliance with the performance of
any obligation or other act of any other party hereto or (b) waive any
inaccuracy in the representations and warranties contained herein or in any
document delivered pursuant hereto. Any such extension or waiver shall be valid
if set forth in an instrument in writing signed by the party or parties to be
bound thereby.
 
     SECTION 9.05.  Expenses.  (a) Except as set forth in this Section 9.05, all
Expenses incurred in connection with this Agreement and the Merger shall be paid
by the party incurring such Expenses, whether or not the Merger is consummated,
except that Parent and the Company each shall pay one-half of all Expenses
incurred solely for printing, filing and mailing the Registration Statement and
the Proxy Statement and all SEC and other regulatory filing fees incurred in
connection with the Registration Statement and the Proxy Statement and any fees
required to be paid under the HSR Act.
 
     (b) In the event that (i) Parent shall terminate this Agreement pursuant to
Section 9.01(e); (ii) the Company shall terminate this Agreement pursuant to
Section 9.01(i); or (iii) (A) Parent shall terminate this Agreement pursuant to
Section 9.01(f) which termination is permissible solely due to the Company's
stockholders having failed to approve and adopt this Agreement and the Merger at
the Company Stockholders' Meeting, (B) at the time of such failure to so approve
this Agreement, there shall exist or be proposed a Competing Transaction with
respect to the Company and (C) within 12 months thereafter, the Company shall
enter into a definitive agreement with respect to any Competing Transaction or
any Competing Transaction shall be consummated; then, in the case of clause (i),
(ii) or (iii) of this Section 9.05(b), promptly (and in any event within two
business days following demand therefor) after such termination or, in the case
of clause (iii) of this Section 9.05(b), promptly after the execution and
delivery of such agreement or such consummation, the Company shall pay to Parent
an amount equal to $5,500,000 plus all of Parent's Expenses, as evidenced by
reasonable documentation, up to an aggregate of $1,000,000.
 
     (c) In the event that the Company shall terminate this Agreement pursuant
to Section 9.01(d) or Section 9.01(f)(ii), Parent shall pay to the Company
within two business days after such termination an amount equal to $5,500,000 in
the event of termination pursuant to Section 9.01(d) or $2,000,000 in the event
of termination pursuant to Section 9.01(f)(ii), in either case, plus all of the
Company's Expenses, as
 
                                      A-41
<PAGE>   362
 
evidenced by reasonable documentation, and in an amount no greater than
$1,000,000, by wire transfer of immediately available funds to an account
designated by the Company; provided, however, that, in the event both the
Company and Parent would otherwise be entitled to payments under this Section
9.05 in connection with the termination of this Agreement pursuant to both
Sections 9.01(f)(i) and (f)(ii), neither party shall be required to make any
payment under this Section 9.05.
 
     (d) In the event that Parent shall terminate this Agreement pursuant to
Section 9.01(f)(i) and Parent is not otherwise entitled to payment pursuant to
Section 9.05(b), the Company shall pay to Parent within two business days after
such termination an amount equal to $2,000,000 plus all of Parent's Expenses, as
evidenced by reasonable documentation, and in an amount no greater than
$1,000,000, by wire transfer of immediately available funds to an account
designated by Parent; provided, however, that, in the event both the Company and
Parent would otherwise be entitled to payments under this Section 9.05 in
connection with the termination of this Agreement pursuant to both Sections
9.01(f)(i) and (f)(ii), neither party shall be required to make any payment
under this Section 9.05.

demand for payment and shall be made by wire transfer of immediately available
funds to an account designated by Parent in the notice of demand for payment
delivered pursuant to this Section 9.05(e). In no event shall the Company be
entitled to collect amounts pursuant to this Section 9.05 relating to more than
one specified event.
 
     (f) In the event that Parent terminates this Agreement pursuant to Section
9.01(g)(i), the Company shall pay to the Parent within two business days after
such termination an amount equal to $1,000,000 in full satisfaction of any and
all obligations hereunder.
 
                                   ARTICLE X
 
                               GENERAL PROVISIONS
 
     SECTION 10.01.  Non-Survival of Representations and Warranties.  The
representations and warranties in this Agreement shall terminate at the
Effective Time or upon the termination of this Agreement pursuant to Section
9.01, as the case may be. This Section 10.01 shall not limit any covenant or
agreement herein which by its terms contemplates performance after the Effective
Time. Each party agrees that, except for the representations and warranties
contained in this Agreement and the Parent Disclosure Schedule and the Company
Disclosure Schedule, no party hereto has made any other representations and
warranties, and each party hereby disclaims any other representations and
warranties made by itself or any of its officers, directors, employees, agents,
financial and legal advisors or other representatives, with respect to the
execution and delivery of this Agreement or the Merger contemplated herein,
notwithstanding the delivery or disclosure to any other party or any party's
representatives of any documentation or other information with respect to any
one or more of the foregoing.
 
     SECTION 10.02.  Notices.  All notices, requests, claims, demands and other
communications hereunder shall be in writing and shall be given (and shall be
deemed to have been duly given upon receipt) by delivery in person, by telecopy
or facsimile, by registered or certified mail (postage prepaid, return receipt
requested) or by a nationally recognized courier service to the respective
parties at their addresses set forth on the signature pages to this Agreement
(or at such other address for a party as shall be specified in a notice given in
accordance with this Section 10.02).
 
     SECTION 10.03.  Severability.  If any term or other provision of this
Agreement is invalid, illegal or incapable of being enforced by any rule of Law
or public policy, all other conditions and provisions of this Agreement shall
nevertheless remain in full force and effect so long as the economic or legal
substance of the Merger is not affected in any manner materially adverse to any
party. Upon such determination that any term or other provision is invalid,
illegal or incapable of being enforced, the parties hereto shall negotiate in
good faith to modify this Agreement so as to effect the original intent of the
parties as closely as possible in a
 
                                      A-42
<PAGE>   363
 
mutually acceptable manner to the fullest extent permitted by applicable Law in
order that the Merger may be consummated as originally contemplated to the
fullest extent possible.
 
     SECTION 10.04.  Assignment; Binding Effect; Benefit.  Neither this
Agreement nor any of the rights, interests or obligations hereunder shall be
assigned by any of the parties hereto (whether by operation of Law or otherwise)
without the prior written consent of the other parties hereto; provided,
however, that Parent may assign its rights, interests and obligations hereunder
to any successor or parent entity of Parent whose shares are registered under
Section 12 of the Exchange Act (or will be so registered at the Effective Time).
Subject to the preceding sentence, this Agreement shall be binding upon and
shall inure to the benefit of the parties hereto and their respective successors
and permitted assigns. Notwithstanding anything contained in this Agreement to
the contrary, other than Section 7.04, nothing in this Agreement, expressed or
implied, is intended to confer on any person other than the parties hereto or
their respective successors and permitted assigns any rights or remedies under
or by reason of this Agreement.
 
     SECTION 10.05.  Incorporation of Exhibits.  The Parent Disclosure Schedule,
the Company Disclosure Schedule and all Exhibits attached hereto and referred to
herein are hereby incorporated herein and made a part of this Agreement for all
purposes as if fully set forth herein.
 
     SECTION 10.06.  Governing Law.  THIS AGREEMENT SHALL BE GOVERNED BY, AND
CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF DELAWARE
(WITHOUT REFERENCE TO CONFLICT OF LAW PRINCIPLES OTHER THAN THOSE DIRECTING
DELAWARE LAW). WAG, PARENT, MERGER SUB AND THE COMPANY EACH HEREBY IRREVOCABLY
SUBMITS TO THE JURISDICTION OF ANY DELAWARE OR FEDERAL COURT SITTING IN THE CITY
OF WILMINGTON, DELAWARE, IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING
TO THIS AGREEMENT, AND WAG, PARENT, MERGER SUB AND THE COMPANY EACH HEREBY
IRREVOCABLY AGREES THAT ALL CLAIMS IN RESPECT OF SUCH ACTION OR PROCEEDING MAY
BE HEARD AND DETERMINED IN SUCH DELAWARE STATE COURT OR SUCH FEDERAL COURT. WAG,
PARENT, MERGER SUB AND THE COMPANY EACH HEREBY IRREVOCABLY WAIVES, TO THE
FULLEST EXTENT IT MAY EFFECTIVELY DO SO, THE DEFENSE OF AN INCONVENIENT FORUM TO
THE MAINTENANCE OF SUCH ACTION OR PROCEEDING.
 
     SECTION 10.07.  Waiver of Jury Trial.  EACH PARTY HERETO HEREBY IRREVOCABLY
WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY PROCEEDING (WHETHER BASED ON CONTRACT,
TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY
TRANSACTION OR AGREEMENT CONTEMPLATED HEREBY OR THE ACTIONS OF ANY PARTY HERETO
IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE OR ENFORCEMENT HEREOF.
 
     SECTION 10.08.  Construction.  The parties have participated jointly in the
negotiation and drafting of this Agreement. In the event an ambiguity or
question of intent or interpretation arises, this Agreement shall be construed
as if drafted jointly by the parties, and no presumption or burden of proof
shall arise favoring or disfavoring any party by virtue of the authorship of any
of the provisions of this Agreement. Any reference to any federal, state, local
or foreign statute or law shall be deemed also to refer to all rules and
regulations promulgated thereunder, unless the context otherwise requires.
"Herein", "hereby", "hereunder", "hereof", "hereinbefore", "hereinafter" and
other equivalent words refer to this Agreement as a whole and not solely to the
particular Article or Section in which such word is used. When a reference is
made in this Agreement to a Section or Exhibit, such reference shall be to a
Section of, or an Exhibit to, this Agreement unless otherwise indicated. ANY
INFORMATION CONTAINED IN ANY SCHEDULE OR EXHIBIT TO THIS AGREEMENT SHALL BE
DEEMED TO HAVE BEEN DISCLOSED IN ALL SUCH SCHEDULES AND EXHIBITS. The table of
contents and headings contained in this Agreement are for reference purposes
only and shall not affect in any way the meaning or interpretation of this
Agreement. Whenever any of the words "include", "includes" or "including" is
used in this Agreement, it shall be deemed to be followed by the words "without
limitation".
 
     SECTION 10.09.  Counterparts.  This Agreement may be executed and delivered
(including by facsimile transmission) in one or more counterparts, and by the
different parties hereto in separate
 
                                      A-43
<PAGE>   364
 
counterparts, each of which when executed and delivered shall be deemed to be an
original but all of which taken together shall constitute one and the same
agreement.
 
     SECTION 10.10.  Acknowledgement.  The Company hereby acknowledges and
agrees that neither the consummation of, nor the failure to consummate, the
acquisition of RCG and Cherry U.K. shall in any way give the Company a right to
terminate the Merger Agreement or the Merger.
 
     SECTION 10.11.  Entire Agreement.  This Agreement (as amended as of October
27, 1998, including the Exhibits, the Mutual Nondisclosure and Confidentiality
Agreement dated as of November 7, 1997 among WAG and the Company, the Parent
Disclosure Schedule and the Company Disclosure Schedule) constitute the entire
agreement among the parties with respect to the subject matter hereof and
supersede all prior agreements and understandings among the parties with respect
thereto. No addition to or modification of any provision of this Agreement shall
be binding upon any party hereto unless made in writing and signed by all
parties hereto.
 
     IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed as of the date first written above by their respective officers
thereunto duly authorized.

     For purposes of calculating the Cash Consideration Pool, the aggregate

shall be estimated for such purpose only to equal 1.5 times the product of (x)

Gentlemen:
 
     We understand that World Access, Inc. (the "Company") and WAXS INC., a
wholly-owned subsidiary of the Company that will become the Company's parent
upon completion of the pending holding company reorganization ("Holdco"), are
considering a proposed business combination with Telco Systems, Inc. ("Telco").
We understand that under this transaction (the "Proposed Transaction"), a
subsidiary of Holdco will be merged with and into Telco (the "Merger"), and each
outstanding share of common stock, par value $0.01 per share ("Telco Common
Stock") of Telco will be converted into the right to receive the consideration
(the "Merger Consideration") consisting of the number of shares of common stock,
par value $0.01 per share, ("Company Common Stock") of the Company (or Holdco)
equal to the Common Exchange Ratio, provided that (i) the value of the
consideration to be received by holders of Telco Common Stock shall not be less
than $12.00 per share (the "Minimum Value") and (ii) the Company (or Holdco) may
elect to pay cash in lieu of issuing shares of Company Common Stock so long as
such cash does not comprise more than 55% of the total consideration to be
received by Telco stockholders (the "Aggregate Cash Pool"). The terms and
conditions of the Proposed Transaction are set forth in more detail in the
Agreement and Plan of Merger and Reorganization dated June 4, 1998 between the
Company, Holdco, Tail Acquisition Corporation and Telco, as proposed to be
amended by the First Amendment thereto (as so amended, the "Merger Agreement").
Capitalized terms used herein but not defined herein shall have the meaning
ascribed to them in the Merger Agreement.
 
     Subject to giving effect to the Minimum Value and the amount the Aggregate
Cash Pool, the Common Exchange Ratio is equal to the quotient of $17.00 divided
by the Closing Date Market Price, provided that if the Closing Date Market Price
determined on the Closing Date is less than $29.00, then the Common Exchange
Ratio shall be equal to 0.5862 shares of the Company Common Stock; and if the
Closing Date Market Price is more than $36.00, then the Common Exchange Ratio
shall be equal to 0.4722 shares of Company Common Stock.
 
     We have been requested by the Company and Holdco to render our opinion with
respect to the fairness, from a financial point of view, to the Company and
Holdco of the Merger Consideration in the Proposed Transaction.
 
     In arriving at our opinion, we reviewed and analyzed: (1) the Merger
Agreement and the proposed First Amendment thereto, (2) such other publicly
available information concerning the Company and Telco which we believe to be
relevant to our inquiry, (3) financial and operating information with respect to
the business, operations and prospects of the Company and Telco furnished to us
by the Company or Telco, (4) trading histories of the Company's Common Stock and
Telco Common Stock and a comparison of these trading histories with those of
other companies which we deemed relevant, (5) a comparison of the historical
financial results and present financial condition of each of the Company and
Telco with those of other companies which we deemed relevant, (6) a comparison
of the financial terms of the Proposed Transaction with the financial terms of
certain other recent transactions which we deemed relevant, (7) certain
potential pro forma effects of the Merger on the Company, and (8) certain
historical data relating to percentage premiums paid in acquisitions of publicly
traded companies. In addition, we have had discussions with the managements of
the Company and Telco concerning their respective businesses, operations,
assets, present condition and future prospects and undertook such other studies,
analyses and investigations as we deemed appropriate.

     We have assumed and relied upon the accuracy and completeness of the
financial and other information used by us in arriving at our opinion without
independent verification. With respect to the financial forecasts/ projections
of the Company and Telco, we have assumed that such forecasts/projections have
been reasonably prepared on bases reflecting the best currently available
estimates and judgments of the managements of the Company and Telco as to the
future financial performance of the Company and Telco. In arriving at our
opinion, we have conducted only a limited physical inspection of the properties
and facilities of the Company and Telco and have not made nor obtained any
evaluations or appraisals of the assets or liabilities of the Company or Telco.
Our opinion is necessarily based upon market, economic and other conditions as
they exist on, and can be evaluated as of, the date of this letter.
 
     We have acted as financial advisor to the Company and Holdco in connection
with the Proposed Transaction and will receive a fee for our services. In
addition, the Company has agreed to indemnify us for certain liabilities arising
out of the rendering of this opinion. We have also performed various investment
banking services for the Company in the past (including serving as a managing
underwriter in the follow-on public equity offering by the Company on September
26, 1996 and as financial advisor in the Company's pending acquisitions of
Cherry Communications Incorporated d/b/a Resurgens Communication Group and
Cherry Communications U.K. Limited) and have received customary fees for such
services. In the ordinary course of our business, we actively trade in the
equity securities of the Company for our own account and for the accounts of our
customers and, accordingly, may at any time hold a long or short position in
such securities.
 
     Based upon and subject to the foregoing, we are of the opinion as of the
date hereof that, from a financial point of view, the Merger Consideration in
the Proposed Transaction is fair to the Company and Holdco.

become aware of any information that would cause us to withdraw or modify such

Board of Directors
Telco Systems, Inc.

Norwood, MA 02062
 
Dear Members of the Board:
 
     We understand that Telco Systems, Inc. (the "Company" or "Telco Systems"),
World Access, Inc. ("WAG"), WAXS INC., a wholly-owned subsidiary of WAG
("Parent"), and Tail Acquisition Corporation, a wholly-owned subsidiary of WAG
(the "Merger Sub"), are parties to an Agreement and Plan of Merger and
Reorganization, dated June 4, 1998 (the "Agreement"), providing for the merger
of the Company and Merger Sub (the "Merger"). We also understand that the
parties now propose to amend the Agreement to provide that, pursuant to the
Merger, each share of Telco Systems common stock ("Telco Systems Common Stock")
shall be converted into the right to receive shares of WAG common stock ("WAG
Common Stock") or a combination of cash (subject to the limitation provided in
the First Amendment (the "Amendment")) and WAG Common Stock in accordance with
the "Common Exchange Ratio" and, if applicable, a pro-rata portion of the
"Top-Up Consideration Pool" (as such terms are defined in the Amendment). The
Merger is intended to be a reorganization within the meaning of Section 368 of
the United States Internal Revenue Code of 1986, as amended. The terms and
conditions of the above described Merger are more fully detailed in the
Agreement and Amendment.
 
     You have requested our opinion as to whether the consideration to be
received by Telco Systems stockholders in the Merger is fair, from a financial
point of view, to such stockholders.
 
     Broadview International LLC focuses on providing merger and acquisition
advisory services to information technology ("IT"), communications, and media
companies. In this capacity, we are continually engaged in valuing such
businesses, and we maintain an extensive database of IT, communications, and
media mergers and acquisitions for comparative purposes. We are currently acting
as financial advisor to Telco Systems' Board of Directors and will receive a fee
from Telco Systems upon the successful conclusion of the Merger.
 
     In rendering our opinion, we have, among other things:
 
          (1) reviewed the terms of the Agreement and the associated exhibits
     thereto dated June 4, 1998;
 
          (2) reviewed the terms of the Amendment;
 
          (3) reviewed Telco Systems' annual report and Form 10-K for the fiscal

     May 31, 1998, including the unaudited financial statements included
     therein, and the unaudited financial information of Telco Systems for its
     twelve months ended August 30, 1998 included in a Telco Systems press
     release dated September 17, 1998;
 
          (4) reviewed certain internal financial and operating information,
     including projections through February 29, 2000, for Telco Systems prepared
     by Telco Systems' management;
 
          (5) participated in discussions with Telco Systems' management
     concerning the operations, business strategy, current financial performance
     and prospects for Telco Systems;

     rationale for the Merger;

          (8) compared certain aspects of the financial performance of Telco
     Systems with public companies we deemed comparable;
 
          (9) considered the effect on Telco Systems of the possible payment of

     transaction contemplated by the Agreement in lieu of entering into the
     Amendment;
 
          (10) analyzed available information, both public and private,
     concerning other mergers and acquisitions we believe to be comparable in
     whole or in part to the Merger;
 
          (11) reviewed WAG's annual report and Form 10-K for the fiscal year
     ended December 31, 1997, including the audited financial statements
     included therein, and WAG's Form 10-Q/A for the three months ended June 30,
     1998, including the unaudited financial statements included therein;
 
          (12) reviewed certain internal financial and operating information for

          (13) participated in discussions with WAG management and RCG (as

     strategy, financial performance and prospects for WAG, RCG and Cherry U.K.
     (as defined in the Agreement);
 
          (14) reviewed the recent reported closing prices and trading activity

     WAG;
 
          (19) prepared pro forma consolidated income statements through
     December 31, 1999 based on forecasts through December 31, 1999 provided by
     the managements of WAG and Telco Systems;
 
          (20) assisted in negotiations and discussions related to the Merger
     among Telco Systems, WAG and their financial and legal advisors; and
 
          (21) conducted other financial studies, analyses and investigations as
     we deemed appropriate for purposes of this opinion.
 
     In rendering our opinion, we have relied, without independent verification,
on the accuracy and completeness of all the financial and other information
(including without limitation the representations and warranties contained in
the Agreement and the Amendment) that was publicly available or furnished to us
by Telco Systems, WAG or WAG's financial advisor. With respect to the financial
projections and forecasts examined by us, we have assumed that they were
reasonably prepared and reflected the best available

estimates and good faith judgments of the management of Telco Systems and WAG as
to the future performance of Telco Systems and WAG, respectively. We have
neither made nor obtained an independent appraisal or valuation of any of WAG's
or Telco Systems' assets.
 
     Based upon and subject to the foregoing, we are of the opinion that the
consideration to be received by Telco Systems stockholders in the Merger is
fair, from a financial point of view, to such stockholders.
 
     For purposes of this opinion, we have assumed that neither Telco Systems
nor WAG is currently involved in any material transaction other than the
following: the Merger, other transactions of which we are aware including those
relating to the Synaptyx transaction, the Resurgens Transaction, the Holding
Company Reorganization and those activities undertaken in the ordinary course of
conducting their respective businesses. Our opinion is necessarily based upon
market, economic, financial and other conditions as they exist and can be
evaluated as of the date of this opinion, and any change in such conditions may
impact this opinion. We express no opinion as to the price at which WAG Common
Stock will trade at any time.
 
     This opinion speaks only as of the date hereof. It is understood that this
opinion is for the information of the Board of Directors of Telco Systems in
connection with its consideration of the Merger and does not constitute a
recommendation to any Telco Systems stockholder as to how such stockholder
should vote on the Merger. This opinion may not be published or referred to, in
whole or part, without our prior written permission, which shall not be
unreasonably withheld. Broadview International LLC hereby consents to references
to and the inclusion of this opinion in its entirety in the Joint Proxy
Statement/Prospectus to be distributed to Telco Systems stockholders in
connection with the Merger.
 
                                          Sincerely,

deliver this Agreement and to consummate the transactions contemplated hereby.
The execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby have been duly authorized by all necessary
action (corporate or otherwise) on the part of such Stockholder. This Agreement
has been duly executed and delivered by or on behalf of such Stockholder and,
assuming its due authorization, execution and delivery by Parent, constitutes a
legal, valid and binding obligation of such Stockholder, enforceable against
such Stockholder in accordance with its terms, subject to the effect of any
applicable bankruptcy, reorganization, insolvency, moratorium or similar laws
affecting creditors' rights generally and subject, as to enforceability, to the

     SECTION 2.02.  No Conflicts; Required Filings and Consents.  (a) The
execution and delivery of this Agreement by such Stockholder do not, and the

such Stockholder or (if such Stockholder is a corporation) any of its
subsidiaries pursuant to, any note, bond, mortgage, indenture, contract,
agreement, lease, license, permit, franchise or other instrument or obligation
to which such Stockholder is a party or by which such

<PAGE>   375
 
Stockholder or any of its properties is bound or affected, except for any such
breaches, defaults or other occurrences that would not cause or create a
material risk of non-performance or delayed performance by such Stockholder of
its obligations under this Agreement.
 
     (b) The execution and delivery of this Agreement by such Stockholder do
not, and the performance of this Agreement by such Stockholder will not, require
any consent, approval, authorization or permit of, or filing with or
notification to, any governmental or regulatory authority, domestic or foreign,
except (i) for applicable requirements, if any, of the Exchange Act, and the HSR
Act and (ii) where the failure to obtain such consents, approvals,
authorizations or permits, or to make such filings or notifications, would not
prevent or delay the performance by such Stockholder of its obligations under
this Agreement.
 
     SECTION 2.03.  Title to Shares.  Other than with respect to Kopp to the

contemplated hereby by Parent have been duly authorized by all necessary
corporate action on the part of Parent. This Agreement has been duly executed

delivery by the Stockholders, constitutes a legal, valid and binding obligation
of Parent, enforceable against Parent in accordance with its terms.
 
     SECTION 3.02.  No Conflict; Required Filings and Consents.  (a) The
execution and delivery of this Agreement by Parent do not, and the performance
of this Agreement by Parent will not, (i) conflict with or violate the
Certificate of Incorporation or By-laws of Parent, (ii) conflict with or violate
any law, rule, regulation, order, judgment or decree applicable to Parent or by
which Parent or any of its properties is bound or affected, or (iii) result in
any breach of or constitute a default (or an event that with notice or lapse of
time or both would become a default) under, or give to others any rights of
termination, amendment, acceleration or cancellation of, or result in the
creation of a lien or encumbrance on any of the property or assets of Parent
pursuant to, any note, bond, mortgage, indenture, contract, agreement, lease,
license, permit, franchise or other instrument or obligation to which Parent is
a party or by which it or any of its properties is bound or affected, except for
any such breaches, defaults or other occurrences that would not cause or create
a material risk of non-performance or delayed performance by Parent of its
obligations under this Agreement.
 
     (b) The execution and delivery of this Agreement by Parent do not, and the
performance of this Agreement by Parent will not, require any consent, approval,
authorization or permit of, or filing with or notification to, any governmental
or regulatory authority, domestic or foreign, except (i) for applicable
requirements, if any, of the Exchange Act and the HSR Act and (ii) where the
failure to obtain such consents, approvals, authorizations or permits, or to
make such filings or notifications, would not prevent or delay the performance
by Parent of its obligations under this Agreement.

has otherwise complied with subsection (d) of this section and who has neither
voted in favor of the merger or consolidation nor consented thereto in writing
pursuant to sec. 228 of this title shall be entitled to an appraisal by the
Court of Chancery of the fair value of the stockholder's shares of stock under
the circumstances described in subsections (b) and (c) of this section. As used
in this section, the word "stockholder" means a holder of record of stock in a
stock corporation and also a member of record of a nonstock corporation; the
words "stock" and "share" mean and include what is ordinarily meant by those
words and also membership or membership interest of a member of a nonstock
corporation; and the words "depository receipt" mean a receipt or other
instrument issued by a depository representing an interest in one or more
shares, or fractions thereof, solely of stock of a corporation, which stock is
deposited with the depository.
 
     (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to sec. 251 (other than a merger effected pursuant to sec. 251
(g) of this title), sec. 252, sec. 254, sec. 257, sec. 258, sec. 263 or sec. 264
of this title:
 
          (1) Provided, however, that no appraisal rights under this section
     shall be available for the shares of any class or series of stock, which
     stock, or depository receipts in respect thereof, at the record date fixed
     to determine the stockholders entitled to receive notice of and to vote at
     the meeting of stockholders to act upon the agreement of merger or
     consolidation, were either (i) listed on a national securities exchange or
     designated as a national market system security on an interdealer quotation
     system by the National Association of Securities Dealers, Inc. or (ii) held
     of record by more than 2,000 holders; and further provided that no
     appraisal rights shall be available for any shares of stock of the
     constituent corporation surviving a merger if the merger did not require
     for its approval the vote of the stockholders of the surviving corporation
     as provided in subsection (f) of sec. 251 of this title.
 
          (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
     under this section shall be available for the shares of any class or series
     of stock of a constituent corporation if the holders thereof are required
     by the terms of an agreement of merger or consolidation pursuant to
     sec.sec. 251, 252, 254, 257, 258, 263 and 264 of this title to accept for
     such stock anything except:
 
             a. Shares of stock of the corporation surviving or resulting from
        such merger or consolidation, or depository receipts in respect thereof;
 
             b. Shares of stock of any other corporation, or depository receipts
        in respect thereof, which shares of stock (or depository receipts in
        respect thereof) or depository receipts at the effective date of the
        merger or consolidation will be either listed on a national securities
        exchange or designated as a national market system security on an
        interdealer quotation system by the National Association of Securities
        Dealers, Inc. or held of record by more than 2,000 holders;
 
             c. Cash in lieu of fractional shares or fractional depository
        receipts described in the foregoing subparagraphs a. and b. of this
        paragraph; or
 
             d. Any combination of the shares of stock, depository receipts and
        cash in lieu of fractional shares or fractional depository receipts
        described in the foregoing subparagraphs a., b. and c. of this
        paragraph.
 
          (3) In the event all of the stock of a subsidiary Delaware corporation
     party to a merger effected under sec. 253 of this title is not owned by the
     parent corporation immediately prior to the merger, appraisal rights shall
     be available for the shares of the subsidiary Delaware corporation.
 
     (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale
                                       E-1
<PAGE>   382
 
of all or substantially all of the assets of the corporation. If the certificate
of incorporation contains such a provision, the procedures of this section,
including those set forth in subsections (d) and (e) of this section, shall
apply as nearly as is practicable.
 
     (d) Appraisal rights shall be perfected as follows:
 
     (1) If a proposed merger or consolidation for which appraisal rights are
provided under this section is to be submitted for approval at a meeting of
stockholders, the corporation, not less than 20 days prior to the meeting, shall
notify each of its stockholders who was such on the record date for such meeting
with respect to shares for which appraisal rights are available pursuant to
subsections (b) or (c) hereof that appraisal rights are available for any or all
of the shares of the constituent corporations, and shall include in such notice
a copy of this section. Each stockholder electing to demand the appraisal of his
shares shall deliver to the corporation, before the taking of the vote on the
merger or consolidation, a written demand for appraisal of his shares. Such
demand will be sufficient if it reasonably informs the corporation of the
identity of the stockholder and that the stockholder intends thereby to demand
the appraisal of his shares. A proxy or vote against the merger or consolidation
shall not constitute such a demand. A stockholder electing to take such action
must do so by a separate written demand as herein provided. Within 10 days after
the effective date of such merger or consolidation, the surviving or resulting
corporation shall notify each stockholder of each constituent corporation who
has complied with this subsection and has not voted in favor of or consented to
the merger or consolidation of the date that the merger or consolidation has
become effective; or
 
     (2) If the merger or consolidation was approved pursuant to sec. 228 or
sec. 253 of this title, each constituent corporation, either before the
effective date of the merger or consolidation or within ten days thereafter,
shall notify each of the holders of any class or series of stock of such
constituent corporation who are entitled to appraisal rights of the approval of
the merger or consolidation and that appraisal rights are available for any or
all shares of such class or series of stock of such constituent corporation, and
shall include in such notice a copy of this section; provided that, if the
notice is given on or after the effective date of the merger or consolidation,
such notice shall be given by the surviving or resulting corporation to all such
holders of any class or series of stock of a constituent corporation that are
entitled to appraisal rights. Such notice may, and, if given on or after the
effective date of the merger or consolidation, shall, also notify such
stockholders of the effective date of the merger or consolidation. Any
stockholder entitled to appraisal rights may, within 20 days after the date of
mailing of such notice, demand in writing from the surviving or resulting
corporation the appraisal of such holder's shares. Such demand will be
sufficient if it reasonably informs the corporation of the identity of the
stockholder and that the stockholder intends thereby to demand the appraisal of
such holder's shares. If such notice did not notify stockholders of the
effective date of the merger or consolidation, either (i) each such constituent
corporation shall send a second notice before the effective date of the merger
or consolidation notifying each of the holders of any class or series of stock
of such constituent corporation that are entitled to appraisal rights of the
effective date of the merger or consolidation or (ii) the surviving or resulting
corporation shall send such a second notice to all such holders on or within 10
days after such effective date; provided, however, that if such second notice is
sent more than 20 days following the sending of the first notice, such second
notice need only be sent to each stockholder who is entitled to appraisal rights
and who has demanded appraisal of such holder's shares in accordance with this
subsection. An affidavit of the secretary or assistant secretary or of the
transfer agent of the corporation that is required to give either notice that
such notice has been given shall, in the absence of fraud, be prima facie
evidence of the facts stated therein. For purposes of determining the
stockholders entitled to receive either notice, each constituent corporation may
fix, in advance, a record date that shall be not more than 10 days prior to the
date the notice is given, provided, that if the notice is given on or after the
effective date of the merger or consolidation, the record date shall be such
effective date. If no record date is fixed and the notice is given prior to the
effective date, the record date shall be the close of business on the day next
preceding the day on which the notice is given.
 
     (e) Within 120 days after the effective date of the merger or
consolidation, the surviving or resulting corporation or any stockholder who has
complied with subsections (a) and (d) hereof and who is otherwise entitled to
appraisal rights, may file a petition in the Court of Chancery demanding a
determination of the value of the stock of all such stockholders.
Notwithstanding the foregoing, at any time within 60 days after the
                                       E-2
<PAGE>   383
 
effective date of the merger or consolidation, any stockholder shall have the
right to withdraw his demand for appraisal and to accept the terms offered upon
the merger or consolidation. Within 120 days after the effective date of the
merger or consolidation, any stockholder who has complied with the requirements
of subsections (a) and (d) hereof, upon written request, shall be entitled to
receive from the corporation surviving the merger or resulting from the
consolidation a statement setting forth the aggregate number of shares not voted
in favor of the merger or consolidation and with respect to which demands for
appraisal have been received and the aggregate number of holders of such shares.
Such written statement shall be mailed to the stockholder within 10 days after
his written request for such a statement is received by the surviving or
resulting corporation or within 10 days after expiration of the period for
delivery of demands for appraisal under subsection (d) hereof, whichever is
later.
 
     (f) Upon the filing of any such petition by a stockholder, service of a
copy thereof shall be made upon the surviving or resulting corporation, which
shall within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the addresses
therein stated. Such notice shall also be given by 1 or more publications at
least 1 week before the day of the hearing, in a newspaper of general
circulation published in the City of Wilmington, Delaware or such publication as
the Court deems advisable. The forms of the notices by mail and by publication
shall be approved by the court, and the costs thereof shall be borne by the
surviving or resulting corporation.
 
     (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights. The Court may require the stockholders who have demanded an
appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.
 
     (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or expectation of the merger or
consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors, including the rate of
interest which the surviving or resulting corporation would have had to pay to
borrow money during the pendency of the proceeding. Upon application by the
surviving or resulting corporation or by any stockholder entitled to participate
in the appraisal proceeding, the Court may, in its discretion, permit discovery
or other pretrial proceedings and may proceed to trial upon the appraisal prior
to the final determination of the stockholder entitled to an appraisal. Any
stockholder whose name appears on the list filed by the surviving or resulting
corporation pursuant to subsection (f) of this section and who has submitted his
certificates of stock to the Register in Chancery, if such is required, may
participate fully in all proceedings until it is finally determined that he is
not entitled to appraisal rights under this section.
 
          (i) The Court shall direct the payment of the fair value of the
     shares, together with interest, if any, by the surviving or resulting
     corporation to the stockholders entitled thereto. Interest may be simple or
     compound, as the Court may direct. Payment shall be so made to each such
     stockholder, in the case of holders of uncertificated stock forthwith, and
     the case of holders of shares represented by certificates upon the
     surrender to the corporation of the certificates representing such stock.
     The Court's decree may be enforced as other decrees in the Court of
     Chancery may be enforced, whether such surviving or resulting corporation
     be a corporation of this State or of any state.
 
                                       E-3
<PAGE>   384
 
          (j) The costs of the proceeding may be determined by the Court and
     taxed upon the parties as the Court deems equitable in the circumstances.
     Upon application of a stockholder, the Court may order all or a portion of
     the expenses incurred by any stockholder in connection with the appraisal
     proceeding, including, without limitation, reasonable attorney's fees and
     the fees and expenses of experts, to be charged pro rata against the value
     of all the shares entitled to an appraisal.
 
          (k) From and after the effective date of the merger or consolidation,
     no stockholder who has demanded his appraisal rights as provided in
     subsection (d) of this section shall be entitled to vote such stock for any
     purpose or to receive payment of dividends or other distributions on the
     stock (except dividends or other distributions payable to stockholders of
     record at a date which is prior to the effective date of the merger or
     consolidation); provided, however, that if no petition for an appraisal
     shall be filed within the time provided in subsection (e) of this section,
     or if such stockholder shall deliver to the surviving or resulting
     corporation a written withdrawal of his demand for an appraisal and an
     acceptance of the merger or consolidation, either within 60 days after the
     effective date of the merger or consolidation as provided in subsection (e)
     of this section or thereafter with the written approval of the corporation,
     then the right of such stockholder to an appraisal shall cease.
     Notwithstanding the foregoing, no appraisal proceeding in the Court of
     Chancery shall be dismissed as to any stockholder without the approval of
     the Court, and such approval may be conditioned upon such terms as the
     Court deems just.
 
          (l) The shares of the surviving or resulting corporation to which the
     shares of such objecting stockholders would have been converted had they
     assented to the merger or consolidation shall have the status of authorized
     and unissued shares of the surviving or resulting corporation. (Last
     amended by Ch. 120, L. '97, eff. 7-1-97.)

Agreement and the Benefits granted thereunder.

all capitalized terms used in the Agreement shall have the same meaning as in
the Plan, and the Agreement shall be subject to all of the terms of the Plan.

                                   ARTICLE XI
 
                                 TANDEM AWARDS

                  PAYMENT, DIVIDENDS, DEFERRAL AND WITHHOLDING
 
     12.1 Payment.  Upon the exercise of an Option or in the case of any other
Benefit that requires a payment by a Participant to the Company, the amount due
the Company is to be paid:
 
          (a) in cash;
 
          (b) by the surrender of all or part of a Benefit (including the
     Benefit being exercised);
 
          (c) by the tender to the Company of Shares owned by the Participant
     and registered in his or her name having a Fair Market Value equal to the
     amount due to the Company;
 
          (d) in other property, rights and credits, deemed acceptable by the
     Committee, including the Participant's promissory note; or
 
          (e) by any combination of the payment methods specified in (a) through
     (d) above.
 
     Notwithstanding the foregoing, any method of payment other than in cash may
be used only with the consent of the Committee or if and to the extent so
provided in an Agreement. The proceeds of the sale of Shares purchased pursuant
to an Option and any payment to the Company for other Benefits shall be added to
the general funds of the Company or to the reacquired Shares held by the
Company, as the case may be, and used for general corporate purposes of the
Company as the Board shall determine.
 
     12.2 Dividend Equivalents.  In the sole discretion of the Committee, grants
of Benefits in Shares or Share equivalents may include dividend or dividend
equivalent payments or dividend credit rights.
 
     12.3 Optional Deferral.  The right to receive any Benefit under the Plan
may, at the request of the Participant, be deferred for such period and upon
such terms as the Committee shall determine, which may include crediting of
dividends on deferrals denominated in shares.
 
     12.4 Code Section 162(m).  The Committee, in its sole discretion, may
require that one or more Agreements contain provisions which provide that, in
the event Section 162(m) of the Code, or any successor provision relating to
excessive Employee remuneration, would operate to disallow a deduction by the
Company for all or part of any Benefit under the Plan, a Participant's receipt
of the portion of such Benefit that would not be deductible by the Company shall
be deferred until the next succeeding year or years in which the Participant's
remuneration does not exceed the limit set forth in such provision of the Code.
 
     12.5 Withholding.  The Company may, at the time any distribution is made
under the Plan, or at the time any Option is exercised, withhold from such
distribution of Shares issuable upon the exercise of an Option, any amount
necessary to satisfy federal, state and local withholding requirements with
respect to such distribution or exercise of such Option. Such withholding may be
satisfied, at the Company's option, either by cash or the Company's withholding
of Shares. Agreements may contain withholding provisions applicable only to
Participants who are subject to Section 16 of the Exchange Act.

                                    OPTIONS

granted by the Committee under the Plan.
 
     13.2 Option Price.  The purchase price for Shares under any ISO shall be no
less than the Fair Market Value of the Shares at the time the Option is granted
(or, in the case of a greater-than-10% stockholder under Section 422(b)(6) of
the Code, 110% of Fair Market Value).
 
     13.3 Other Requirements for ISOs.  The terms of each Option which is
intended to qualify as an ISO shall meet all requirements of Section 422 of the
Code or any successor statute in effect from time to time, including (without
limitation) the requirement that the grantee be an Employee of the Company, a
Parent and/or a Subsidiary.
 
     13.4 NQSOs.  The terms of each NQSO shall provide that such Option will not
be treated as an ISO.
 
     13.5 Determination by Committee.  Except as otherwise provided in Sections
13.2 through Section 13.4, the terms of all Options shall be determined by the
Committee.
 
                                  ARTICLE XIV
 
                                RESTRICTED STOCK
 
     14.1 Description.  The Committee may grant Benefits in Shares as Restricted
Stock with such terms and conditions as may be determined in the sole discretion
of the Committee. Shares of Restricted Stock shall be issued and delivered at
the time of the grant or as otherwise determined by the Committee, but shall be
subject to forfeiture until provided otherwise in the applicable Agreement or
the Plan. Each certificate representing Shares of Restricted Stock shall bear a
legend referring to the Plan and any risk of forfeiture of the Shares and
stating that such Shares are nontransferable until all restrictions have been
satisfied and the legend has been removed. At the discretion of the Committee,
the grantee may or may not be entitled to full voting and dividend rights with
respect to all shares of Restricted Stock from the date of grant. The Committee
may (but is not obligated to) require that any dividends on such shares shall be
automatically deferred and reinvested in additional Restricted Stock subject to
the same restrictions as the underlying Benefit.
 
     14.2 Cost of Restricted Stock.  Grants of Shares of Restricted Stock shall
be made at such cost as the Committee shall determine and may be issued for no
monetary consideration, subject to applicable state law.
 
     14.3 Nontransferability.  Shares of Restricted Stock shall not be
transferable until after the removal of the legend with respect to such Shares.
 
                                   ARTICLE XV
 
                               PERFORMANCE SHARES
 
     15.1 Description.  Performance Shares represent the right of a Participant
to receive Shares or cash equal to the Fair Market Value of such shares at a
future date in accordance with the terms and conditions of a grant. The terms
and conditions shall be determined by the Committee, in its sole discretion, but
generally are expected to be based substantially upon the attainment of targeted
financial and/or operational performance objectives.
 
     15.2 Grant.  The Committee may grant an award of Performance Shares at such
times, in such amounts and under such terms and conditions as it deems
appropriate.

                  OTHER STOCK BASED AWARDS AND OTHER BENEFITS
 
     16.1 Other Stock Based Awards.  The Committee shall have the right to grant
Other Stock Based Awards which may include, without limitation, the grant of
Shares based on certain conditions, the payment of cash based on the market
performance of the Common Stock, and the grant of securities convertible into
Shares.
 
     16.2 Other Benefits.  The Committee shall have the right to provide other
types of Benefits under the Plan in addition to those specifically listed, if
the Committee believes that such Benefits would further the purposes for which
the Plan has been established.
 
                                  ARTICLE XVII
 
                            MISCELLANEOUS PROVISIONS
 
     17.1 Termination of Service.  If the employment of a Participant with or
the provision of services by a Participant to the Company terminates for any
reason, all unexercised, deferred, and unpaid Benefits may be exercisable or
paid only in accordance with rules established by the Committee. These rules may
provide, as the Committee in its sole discretion may deem appropriate, for the
expiration, forfeiture, continuation, or acceleration of the vesting, except as
may be provided in an Agreement, of all or part of the Benefits.
 
     17.2 Unfunded Status of the Plan.  The Plan is intended to constitute an
"unfunded" plan for incentive and deferred compensation. With respect to any
payments or deliveries of Shares not yet made to a Participant by the Company,
nothing contained herein shall give any rights that are greater than those of a
general creditor of the Company. The Committee may authorize the creation of
trusts or other arrangements to meet the obligations created under the Plan to
deliver Shares or payments hereunder consistent with the foregoing.
 
     17.3 Designation of Beneficiary.  A Participant may file with the Committee
a written designation of a beneficiary or beneficiaries (subject to such
limitations as to the classes and number of beneficiaries and contingent
beneficiaries as the Committee may from time to time prescribe) to exercise, in
the event of the death of the Participant, an Option, or to receive, in such
event, any Benefits. The Committee reserves the right to review and approve
beneficiary designations. A Participant may from time to time revoke or change
any such designation of beneficiary and any designation of beneficiary under the
Plan shall be controlling over any other disposition, testamentary or otherwise;
provided, however, that if the Committee shall be in doubt as to the right of
any such beneficiary to exercise any Option or to receive any Benefit, the
Committee may determine to recognize only an exercise by the legal
representative of the recipient, in which case the Company, the Committee and
the members thereof shall not be under any further liability to anyone.
 
     17.4 Nontransferability.  Unless otherwise determined by the Committee or
specified in an Agreement (and subject to Section 10.3 hereof), (i) no Benefit
granted under this Plan may be transferred or assigned by the Participant to
whom it is granted other than by beneficiary designation, will, pursuant to the
laws of descent and distribution, or pursuant to a qualified domestic relations
order, and (ii) a Benefit granted under this Plan may be exercised, during the
Participant's lifetime, only by the Participant or by the Participant's guardian
or legal representative; except that, no ISO may be transferred or assigned
pursuant to a qualified domestic relations order or exercised, during the
Participant's lifetime, by the Participant's guardian or legal representative.
 
     17.5 Rule 16b-3.  With respect to Participants subject to Section 16 of the
Exchange Act, transactions under this Plan are intended to comply with all
applicable provisions of Rule 16b-3 or its successors under the Exchange Act. To
the extent any provision of the Plan or action by the Plan administrators fails
to so comply, it shall be deemed null and void, to the extent permitted by law
and deemed advisable by the Committee.
 
     17.6 Underscored References.  The underscored references contained in the
Plan and in any Agreement are included only for convenience, and they shall not
be construed as a part of the Plan or Agreement or in any respect affecting or
modifying its provisions.

<PAGE>   394
 
     17.7 Number and Gender.  The masculine, feminine and neuter, wherever used
in the Plan or in any Agreement, shall refer to either the masculine, feminine
or neuter; and, unless the context otherwise requires the singular shall include
the plural and the plural the singular.
 
     17.8 Governing Law.  The place of administration of the Plan and each
Agreement shall be in the State of Georgia. The corporate law of the Company's
state of incorporation shall govern issues related to the validity and issuance
of Shares. Otherwise, this Plan and each Agreement shall be construed and
administered in accordance with the laws of the State of Georgia, without giving
effect to principles relating to conflict of laws.
 
     17.9 Purchase for Investment.  The Committee may require each Person
purchasing or receiving shares pursuant to a Benefit to represent to and agree
with the Company in writing that such Person is acquiring the Shares for
investment and without a view to distribution or resale. The certificates for
such Shares may include any legend which the Committee deems appropriate to
reflect any restrictions on transfer. All certificates for Shares delivered
under the Plan shall be subject to such stock-transfer orders and other
restrictions as the Committee may deem advisable under all applicable laws,
rules and regulations, and the Committee may cause a legend or legends to be put
on any such certificates to make appropriate references to such restrictions.
 
     17.10 No Employment Contract.  Neither the adoption of the Plan nor any
Benefit granted hereunder shall confer upon any Employee, Director, Consultant,
Independent Contractor or other agent any right to continued employment with or
services to the Company or any Affiliate, nor shall the Plan or any Benefit
interfere in any way with the right of the Company or any Affiliate to terminate
the employment or provision of services of any of its Employees, Directors,
Consultants, Independent Contractors or other agents at any time.
 
     17.11 No Effect on Other Benefits.  The receipt of Benefits under the Plan
shall have no effect on any benefits to which a Participant may be entitled from
the Company or any Affiliate under another plan or otherwise, or preclude a
Participant from receiving any such benefits.

                           INDEMNIFICATION AGREEMENT
 
     THIS INDEMNIFICATION AGREEMENT (the "Agreement") is made as of           ,
1998 by and between WORLD ACCESS, INC., a Delaware corporation (the "Company"),
and                ("Indemnitee"), a director and/or officer of the Company.
 
     WHEREAS, Article XI of the Certificate of Incorporation of the Company (the
"Certificate") provides that the Company, among other things, shall indemnify
and hold harmless all persons whom it shall have the power to indemnify under
Section 145 of the General Corporation Law of the State of Delaware to the
fullest extent permitted thereunder; and
 
     WHEREAS, in recognition of Indemnitee's need for protection against
personal liability in order to enhance Indemnitee's continued service to the
Company and Indemnitee's reliance on the provisions of Article XI of the
Certificate requiring indemnification under certain circumstances, and in part
to provide Indemnitee with specific contractual assurance that indemnification
protection will be available and to implement such provision, the Company wishes
to provide in this Agreement for the indemnification of, and the advancement of
expenses to, Indemnitee to the fullest extent permitted by law;
 
     NOW, THEREFORE, in consideration of the mutual premises and covenants
contained herein, and for other good and valuable consideration, the receipt and

follows:
 
     SECTION 1. Right to Indemnification.  The Company shall to the fullest
extent permitted by applicable law as then in effect indemnify and hold harmless
the Indemnitee in the event that he was or is a party to or is involved or
becomes involved in any manner (including, without limitation, as a party,
intervenor or a witness) or is threatened to be made so involved in any
threatened, pending or completed investigation, claim, action, suit or
proceeding, whether civil, criminal, administrative or investigative (including,
without limitation, any action, suit or proceeding by or in the right of the
Company to procure a judgment in its favor) (a "Proceeding") by reason of the
fact that he, or a person of whom he is the legal representative, is or was a
director and/or officer of the Company, or is or was serving at the request of
the Company as a director, officer, partner (limited or general) or agent of
another corporation, partnership, joint venture, limited liability company,
trust or other enterprise (including, without limitation, service with respect
to an employee benefit plan) against all expenses, liabilities and losses
(including attorneys' fees, judgments, fines, taxes, penalties and amounts paid
or to be paid in settlement) reasonably incurred by him in connection with such
Proceeding. Such indemnification shall be a contract right and shall include the
right to receive payment in advance of any expenses incurred by the Indemnitee
in connection with such Proceeding, consistent with the provisions of applicable
law as then in effect.
 
     SECTION 2. Indemnification Not Exclusive Right.  The right of
indemnification provided in this Agreement shall not be exclusive of and shall
be in addition to, and not in lieu of, any other rights to which the Indemnitee
may otherwise be entitled under applicable law, the Bylaws or otherwise. Nothing
in this Agreement shall diminish or otherwise restrict the Indemnitee's right to
indemnification under applicable law, the Certificate or otherwise. The
provisions of this Agreement shall inure to the benefits of the heirs,
executors, administrators and other legal representatives of the Indemnitee and
shall be applicable to Proceedings commenced or continuing after the adoption of
this Agreement, whether arising from acts or omissions occurring before or after
its execution and delivery.
 
     SECTION 3. Advancement of Expenses; Procedures; Presumptions and Effect of
Certain Proceedings; Remedies.  In furtherance, but not in limitation of the
foregoing provisions, the following procedures, presumptions and remedies shall
apply with respect to the advancement of expenses and the right to
indemnification under this Agreement:
 
          3.1. Advancement of Expenses.  All reasonable expenses incurred by or
     on behalf of the Indemnitee in the defense of or other involvement in or
     otherwise in connection with any Proceeding shall be advanced to the
     Indemnitee by the Company within twenty (20) days after the receipt by the
     Company of a statement or statements from the Indemnitee requesting such
     advance or advances from time to time, whether prior to or after final
     disposition of such Proceeding. Such statement or statements shall
 
                                       H-1
<PAGE>   396
 
     reasonably evidence the expenses incurred by the Indemnitee and, if
     required by law at the time of such advance, shall include or be
     accompanied by an undertaking by or on behalf of the Indemnitee to repay
     the amounts advanced if it should ultimately be determined that the
     Indemnitee is not entitled to be indemnified against such expenses pursuant
     to this Agreement.
 
          3.2. Procedure for Determination of Entitlement to
     Indemnification.  3.2.1. To obtain indemnification under this Agreement,
     the Indemnitee shall submit to the Secretary of the Company a written
     request, including such documentation and information as is reasonably
     available to the Indemnitee and reasonably necessary to determine whether
     and to what extent the Indemnitee is entitled to indemnification (the
     "Supporting Documentation"). The determination of the Indemnitee's
     entitlement to indemnification shall be made not later than sixty (60) days
     after receipt by the Company of the written request for indemnification,
     together with the Supporting Documentation. The Secretary of the Company
     shall, promptly upon receipt of such a request for indemnification, advise
     the Board of Directors of the Company (the "Board of Directors") in writing
     that the Indemnitee has requested indemnification.
 
          3.2.2. The Indemnitee's entitlement to indemnification under this
     Agreement shall be determined in one of the following ways: (A) by a
     majority vote of the Disinterested Directors (as hereinafter defined), even
     though less than a quorum of the Board of Directors; (B) by a written
     opinion of Independent Counsel (as hereinafter defined) if (x) a Change of
     Control (as hereinafter defined) shall have occurred and the Indemnitee so
     requests or (y) there are no Disinterested Directors, or a majority of
     Disinterested Directors, even though less than a quorum, so directs; (C) by
     the stockholders of the Company (but only if a majority of the
     Disinterested Directors, even though less than a quorum of the Board of
     Directors, presents the issue of entitlement to indemnification to the
     stockholders for their determination); or (D) as provided in Section 3.3.
 
          3.2.3. In the event the determination of entitlement to
     indemnification is to be made by Independent Counsel pursuant to Section
     3.2.2, a majority of the Disinterested Directors, or in the absence of any
     Disinterested Directors, a majority of the Board of Directors, shall select
     the Independent Counsel, but only an Independent Counsel to which the
     Indemnitee does not reasonably object; provided, however, that if a Change
     of Control shall have occurred, the Indemnitee shall select such
     Independent Counsel, but only an Independent Counsel to which the Board of
     Directors does not reasonably object.
 
     3.3. Presumptions and Effect of Certain Proceedings.  Except as otherwise
expressly provided in this Agreement, the Indemnitee shall be presumed to be
entitled to indemnification under this Agreement upon submission of a request
for indemnification, together with the Supporting Documentation in accordance
with Section 3.2.1, and thereafter the Company shall have the burden of proof to
overcome that presumption in reaching a contrary determination. In any event, if
the person or persons empowered under Section 3.2 to determine entitlement to
indemnification shall not have been appointed or shall not have made a
determination within sixty (60) days after receipt by the Company of the request
therefor together with the Supporting Documentation, the Indemnitee shall be
deemed to be entitled to indemnification and shall be entitled to such
indemnification unless (A) Indemnitee misrepresented or failed to disclose a
material face in making the request for indemnification or in the Supporting
Documentation or (B) such indemnification is prohibited by law. The termination
of any Proceeding described in Section 1, or of any claim, issue or matter
herein, by judgment, order, settlement or conviction, or upon a plea of nolo
contendere or its equivalent, shall not, of itself, adversely affect the right
of the Indemnitee to indemnification or create a presumption that the Indemnitee
did 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 or, with respect to any
criminal Proceeding, that the Indemnitee had reasonable cause to believe that
his conduct was unlawful.
 
     3.4. Remedies of Indemnitee.  3.4.1. In the event that a determination is
made pursuant to Section 3.2 that the Indemnitee is not entitled to
indemnification under this Agreement, the Indemnitee shall be entitled to seek
an adjudication of his entitlement to such indemnification either, at the
Indemnitee's sole option, in (x) an appropriate court of the State of Delaware
or any other court of competent jurisdiction or (y) an arbitration to be
conducted by a single arbitrator pursuant to the rules of the American
Arbitration Association; it being understood that any such judicial proceeding
or arbitration shall be de novo and the
 
                                       H-2
<PAGE>   397
 
Indemnitee shall not be prejudiced by reason of such adverse shall have the
burden of proving that the Indemnitee is not entitled to indemnification under
this Agreement.
 
     3.4.2. If a determination shall have been made or deemed to have been made,
pursuant to Sections 3.2 or 3.3, that the Indemnitee is entitled to
indemnification, the Company shall be obligated to pay the amounts constituting
such indemnification within five (5) days after such determination has been made
or deemed to have been made and shall be conclusively bound by such
determination unless (A) the Indemnitee misrepresented or failed to disclose a
material fact in making the request for indemnification or in the Supporting
Documentation or (B) such indemnification is prohibited by law. In the event
that advancement of expenses is not timely made pursuant to Section 3.1 or
payment of indemnification is not made within five (5) days after a
determination of entitlement to indemnification has been made or deemed to have
been made pursuant to Section 3.2 or 3.3, the Indemnitee shall be entitled to
seek judicial enforcement of the Company's obligation to pay to the Indemnitee
such advancement of expenses or indemnification. Notwithstanding the foregoing,
the Company may bring an action, in an appropriate court in the State of
Delaware or any other court of competent jurisdiction, contesting the right of
the Indemnitee to receive indemnification hereunder due to the occurrence of an
event described in subclause (A) or (B) of this subsection 3.4.2 (a
"Disqualifying Event"); provided, however, that in any such action the Company
shall have the burden of proving the occurrence of such Disqualifying Event.
 
     3.4.3. The Company shall be precluded from asserting in any judicial
proceeding or arbitration commenced pursuant to this Section 3.4 that the
procedures and presumptions of this Agreement are not valid, binding and
enforceable and shall stipulate in any such court or before any such arbitrator
that the Company is bound by all the provisions of this Agreement.
 
     3.4.4. In the event that the Indemnitee, pursuant to this Section 3.4,
seeks a judicial adjudication of or an award in arbitration to enforce his
rights under, or to recover damages for breach of, this Agreement, the
Indemnitee shall be entitled to recover from the Company, and shall be
indemnified by the Company against, any and all expenses actually and reasonably
incurred by him if the Indemnitee prevails in such judicial adjudication or
arbitration. If it shall be determined in such judicial adjudication or
arbitration that the Indemnitee is entitled to receive part but not all of the
indemnification or advancement of expenses sought, all such expenses incurred by
the indemnitee in connection with such judicial adjudication or arbitration
shall be paid.
 
     3.5. Definitions.  For the purposes of this Section 3:
 
          3.5.1. "Change in Control" means a change in control of the Company of
     a nature that would be required to be reported in response to Item 6(e) of
     Schedule 14A of Regulation 14A promulgated under the Securities Exchange
     Act of 1934, as amended (the "Act"), whether or not the Company is then
     subject to such reporting requirement; provided that, without limitation,
     such a change in control shall be deemed to have occurred if (A) any
     "person" (as such term is used in Sections 13(d) and 14(d) of the Act)
     becomes after the date hereof the "beneficial owner" (as defined in Rule
     13d-3 under the Act), directly or indirectly, of securities of the Company
     representing twenty percent (20%) or more of the combined voting power of
     the Company's then outstanding securities without the prior approval of at
     least two-thirds of the members of the Board of Directors in office
     immediately prior to such acquisition; (B) the Company is a party to a
     merger, consolidation, sale of assets or other reorganization, or a proxy
     contest, as a consequence of which members of the Board of Directors in
     office immediately prior to such transaction or event constitute less than
     a majority of the Board of Directors thereafter; or (C) during any period
     of two (2) consecutive years, individuals who at the beginning of such
     period constituted the Board of Directors (including for this purpose any
     new director whose election or nomination for election by the Company's
     stockholders was approved by a vote of at least a majority of the directors
     then still in office who were directors at the beginning of such period)
     cease for any reason to constitute at least a majority of the Board of
     Directors.
 
          3.5.2. "Disinterested Director" means a director of the Company who is
     not or was not a party to the Proceeding in respect of which
     indemnification is sought by the Indemnitee.
 
                                       H-3
<PAGE>   398
 
          3.5.3. "Independent Counsel" means a law firm or a member of a law
     firm that neither presently is, nor in the past five (5) years has been,
     retained to represent (A) the Company or the Indemnitee in any matter
     material to either such party or (B) any other party to the Proceeding
     giving rise to a claim for indemnification under this Agreement.
     Notwithstanding the foregoing, the term "Independent Counsel" shall not
     include any person who, under the applicable standards of professional
     conduct then prevailing under the law of the State of Delaware, would have
     a conflict of interest in representing either the Company or the Indemnitee
     in an action to determine the Indemnitee's rights under this Agreement.
 
     SECTION 4. Notification and Defense of Claim.  4.1. Promptly after receipt
of notice of the commencement of any action, suit or proceeding, Indemnitee
will, if a claim in respect thereof is to be made against the Company under this
Agreement, notify the Company of the commencement thereof, but the omission so
to notify the Company will not relieve the Company from any liability that the
Company may have to Indemnitee under this Agreement unless the Company is
materially prejudiced thereby. With respect to any such action, suit or
proceeding as to which Indemnitee notifies the Company of the commencement
thereof, (A) the Company will be entitled to participate therein at its own
expense, and (B) except as otherwise provided below, the Company, jointly with
any other indemnifying party similarly notified, will be entitled to assume the
defense thereof with counsel reasonably satisfactory to Indemnitee. After notice
from the Company to Indemnitee of the Company's election so to assume the
defense thereof, the Company will not be liable to Indemnitee under this
Agreement for any legal or other expenses subsequently incurred by Indemnitee in
connection with the defense thereof other than reasonable costs of investigation
or as otherwise provided below. Indemnitee shall have the right to employ
Indemnitee's own counsel in such action, suit or proceeding, but the fees and
disbursements of such counsel incurred after notice from the Company of the
Company's assumption of the defense thereof shall be at the expense of
Indemnitee unless (i) the employment by counsel by Indemnitee has been
authorized by the Company, (ii) Indemnitee shall have reasonably concluded that
there may be a conflict of interest between the Company and Indemnitee in the
conduct of the defense of such action, (iii) such action, suit or proceeding
seeks penalties or other relief against Indemnitee with respect to which the
Company could not provide monetary indemnification to Indemnitee (such as
injunctive relief or incarceration), or (iv) the Company shall not in fact have
employed counsel to assume the defense of such action, in each of which cases
the fees and disbursements of counsel shall be at the expense of the Company.
The Company shall not be entitled to assume the defense of any action, suit or
proceeding brought by or on behalf of the Company, or as to which Indemnitee
shall have reached the conclusion specified in (ii) above, or which involves
penalties or other relief against Indemnitee of the type referred to in (iii)
above. It is acknowledged that a director or former director shall be entitled
under circumstances specified in the Certificate to expenses of separate legal
counsel up to the amount specified therein.
 
     4.2. The Company shall not be liable to indemnify Indemnitee under this
Agreement for any amounts paid in settlement of any action or claim effected
without the Company's written consent. The Company shall not settle any action
or claim in any manner that would impose any penalty or limitation on Indemnitee
without Indemnitee's written consent. Neither the Company nor Indemnitee will
unreasonably withhold consent to any proposed settlement.
 
     SECTION 5. Severability.  If any provision or provisions of this Agreement
shall be held to be invalid, illegal or unenforceable for any reason whatsoever,
(A) the validity, legality and enforceability of the remaining provisions of
this Agreement (including, without limitation, all portions of any paragraph of
this Agreement containing any such provision held to be invalid, illegal or
unenforceable, that are not themselves invalid, illegal or unenforceable) shall
not in any way be affected or impaired thereby, and (B) to the fullest extent
possible, the provisions of this Agreement (including, without limitation, all
portions of any section of this Agreement containing any such provision held to
be invalid, illegal or unenforceable, that are not themselves invalid, illegal
or unenforceable) shall be construed so as to give effect to the intent
manifested by the provision held invalid, illegal or unenforceable.
 
     SECTION 6. Company's Right to Indemnification.  Nothing in this Agreement
shall diminish, limit or otherwise restrict or modify in any way the Company's
right to indemnification or contribution from an
 
                                       H-4
<PAGE>   399
 
Indemnitee or an Indemnitee's obligation to indemnify or hold harmless the
Company under any agreement, instrument, commitment or understanding now or
hereafter in effect.
 
     SECTION 7. Cancellation.  The Company may cancel the provisions of this
Agreement prospectively only upon thirty (30) days' prior written notice to
Indemnitee in order to afford Indemnitee an opportunity to resign as officer
and/or director rather than continue to serve absent indemnification provided
under this Agreement; it being understood that "prospectively only" shall mean
that the Agreement shall remain in full force and effect for all acts or
omissions that occur through the effective date of cancellation.
 
     SECTION 8. Amendments and Waiver.  No amendment, modification or discharge
or this Agreement, and no waiver hereunder, shall be valid or binding unless set
forth in writing and duly executed by both of the parties hereto. Neither the
waiver by any of the parties hereto of a breach of or a default under any of the
provisions of this Agreement, nor the failure of any of the parties, on one or
more occasions, to enforce any of the provisions of this Agreement or to
exercise any right or privilege hereunder shall thereafter be construed as a
waiver of any subsequent breach or default of a similar nature, or as a waiver
of any of such provisions, rights or privileges hereunder. No delay or failure
on the part of any party in exercising any right, power or privilege under this
Agreement or under any other instruments given in connection with or pursuant to
this Agreement shall impair any such right, power or privilege or be construed
as a waiver of any default or any acquiescence therein. No single or partial
exercise of any such right, power or privilege shall preclude the further
exercise of any other right, power or privilege.
 
     SECTION 9. Subrogation.  In the event of payment under this Agreement, the
Company shall be subrogated to the extent of such payment to all of the rights
of recovery of Indemnitee, who shall execute all papers required and shall do
everything that may be necessary to secure such rights, including the execution
and delivery of such documents necessary to enable the Company effectively to
bring suit to enforce such rights.
 
     SECTION 10. No Duplication of Payment.  The Company shall not be liable
under this Agreement to make any payment in connection with any claim made
against Indemnitee to the extent Indemnitee has otherwise actually received
payment (under any insurance policy, the Certificate or otherwise) of the
amounts otherwise indemnifiable hereunder.
 
     SECTION 11. Governing Law; Headings.  This Agreement shall be governed by
and construed and enforced in accordance with the laws of the State of Delaware
applicable to contracts made and to be performed in such state without giving
effect to the principles-of conflicts of laws. The section and other headings
contained in this Agreement are for reference purposes only and shall not affect
in any way the meaning of interpretation of this Agreement.
 
     SECTION 12. Successors; Binding Agreement.  The Company shall require any
successor (whether direct or indirect, by purchase, merger, consolidation or
otherwise) to all or substantially all of the business or assets of the Company,
by agreement in form and substance reasonably satisfactory to Indemnitee,
expressly to assume and agree to perform this Agreement in the same manner and
to the same extent that the Company would be required to perform if no such
succession had taken place. This Agreement shall inure to the benefit of and be
enforceable by Indemnitee's personal or legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees. If
Indemnitee should die while any amounts would still be payable to Indemnitee
hereunder if Indemnitee had continued to live, all such amounts, unless
otherwise provided herein, shall be paid in accordance with the terms of this
Agreement to Indemnitee's devisee, legatee, or other designee, or if there be no
such designee, to Indemnitee's estate.

                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Section 102 of the Delaware General Corporation Law ("DGCL") allows a
corporation to eliminate or limit the personal liability of directors of a
corporation to the corporation or to any of its stockholders for monetary
damages for a breach of fiduciary duty as a director, except (i) for breach of
the director's duty of loyalty, (ii) for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (iii) for
certain unlawful dividends and stock repurchases, or (iv) for any transaction
from which the director derived an improper personal benefit.
 
     Section 145 of the DGCL provides that in the case of any action other than
one by or in the right of the corporation, a corporation may indemnify any
person who was or is a party or is threatened to be made a party to any action,
suit or proceeding, whether civil, criminal, administrative or investigative, by
reason of the fact that 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 such capacity on behalf of another corporation or enterprise, against
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by him in connection with such
action 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.
 
     Section 145 of the DGCL provides that in the case of an action by or in the
right of a corporation to procure a judgment in its favor, a corporation may
indemnify any person who was or is a party or is threatened to be made a party
to any action or suit by reason of the fact that 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 such capacity on behalf of another corporation
or 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 under standards similar to those set forth in the
preceding paragraph, except that no indemnification may be made in respect of
any action or claim as to which such person shall have been adjudged to be
liable to the corporation unless a court determines that such person is fairly
and reasonably entitled to indemnification.
 
     Articles X and XI of the Company's Certificate of Incorporation provides
for indemnification of directors, officers and employees to the fullest extent
permissible under the DGCL.

ITEM 22.  UNDERTAKINGS.
 
     (a) The undersigned registrant hereby undertakes (i) to file, during any
period in which offers or sales are being made, a post-effective amendment to
this registration statement (A) to include any prospectus required by Section
10(a)(3) of the Securities Act of 1933; (B) 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; and (C) 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; (ii) 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; and (iii) 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.
 
     (b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement 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)  (i) The undersigned registrant hereby undertakes as follows: 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.
 
                                      II-3
<PAGE>   404
 
        (ii) The undersigned registrant hereby undertakes that every prospectus:
             (A) that is filed pursuant to paragraph (c)(i) immediately
             preceding or (B) that purports to meet the requirements of Section
             10(a)(3) of the Securities Act of 1933 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 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.
 
     (d) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 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 of
1933 and is, therefore, unenforceable. In the event that such a claim for
indemnification against such 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 registered, 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 whether such
indemnification by it is against public policy as expressed in the Securities
Act of 1933 and will be governed by the final adjudication of such issue.
 
     (e) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference in the Joint Proxy
Statement/Prospectus pursuant to Item 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) The undersigned registrant hereby undertakes 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.

Gentlemen:
 
     We have acted as counsel to World Access, Inc. (formerly known as WAXS INC.
(the "Company")) in connection with the registration by the Company on Form S-4
(hereinafter referred to, together with any amendments thereto, as the
"Registration Statement") under the Securities Act of 1933, as amended (the
"Securities Act"), of an aggregate of up to 8,082,282 shares of common stock,
$.01 par value per share, of the Company (the "Shares") issuable pursuant to
that certain Agreement and Plan of Merger and Reorganization dated as of June 4,
1998, as amended, by and among the Company, WA Telcom Products Co., Inc.
(formerly known as World Access, Inc.), Tail Acquisition Corporation, a Delaware
corporation and wholly-owned subsidiary of the Company, and Telco Systems, Inc.
(as so amended, the "Merger Agreement").
 
     This opinion is being furnished to you in accordance with the requirements
of Item 601(b)(5) of Regulation S-K under the Securities Act.
 
     In connection with this opinion, we have examined such corporate records
and documents and have made such examinations of law as we have deemed
necessary. In rendering this opinion, we have relied, without investigation,
upon various certificates of public officials and of officers and
representatives of the Company. In our examination of documents, we have assumed
the genuineness of all signatures, the authenticity of all documents submitted
to us as originals and the conformity with the originals of all documents
submitted to us as copies.
 
     Based upon the foregoing and subject to the assumptions, qualifications,
limitations and exceptions set forth herein, we are of the opinion that the
Company has the corporate power and authority under the General Corporation Law
of the State of Delaware and its Certificate of Incorporation and Bylaws to
issue the Shares, and the Shares, when issued in accordance with the Merger
Agreement, will be validly issued, fully paid and nonassessable.
 
     We consent to the filing of this opinion as an exhibit to the Registration
Statement and as an exhibit to applications to the securities commissioners of
the various states and other jurisdictions of the United States for registration
or qualification of the Shares in such states and other jurisdictions. We
further consent to the reference to our firm under the caption "Legal Matters"
in the Joint Proxy Statement/Prospectus which is a part of the Registration
Statement. In giving this consent, we do not thereby admit that we are included
in the category of persons whose consent is required under Section 7 of the
Securities Act or the rules and regulations of the Commission.
 
                                          Very truly yours,

                                                                November 9, 1998

Ladies and Gentlemen:
 
     We have acted as counsel to Telco Systems Inc., a Delaware corporation
("Telco Systems"), in connection with the proposed merger (the "Merger") of
Telco Systems with and into Tail Acquisition Corporation ("Merger Sub"), a
Delaware corporation and wholly-owned subsidiary of World Access, Inc., a
Delaware corporation (formerly known as WAXS INC., "New World Access"), pursuant
to the Agreement and Plan of Merger and Reorganization dated as of June 4, 1998,
as amended as of October 27, 1998 by and among WA Telcom Products Co., Inc.
(formerly known as World Access, Inc., "Old World Access"), New World Access,
Merger Sub and Telco Systems (the "Merger Agreement"). Capitalized terms used
but not defined herein shall have the meanings ascribed to such terms in the
Merger Agreement.
 
     This opinion is being furnished to you, at your request, in connection with
the filing by New World Access of the Registration Statement on Form S-4 (the
"Registration Statement") filed on the date hereof with the Securities and
Exchange Commission under the Securities Act of 1933, as amended (the
"Securities Act").
 
     In rendering our opinion set forth below, we have examined and, with the
consent of Old World Access, New World Access, Merger Sub and Telco Systems,
relied upon the accuracy and completeness (which we have neither investigated
nor verified) of the facts, information, covenants, representations and
warranties contained in originals or copies, certified or otherwise identified
to our satisfaction, of the Merger Agreement, including the Exhibits thereto,
the Registration Statement and such other documents and corporate records as we
have deemed necessary or appropriate as a basis for our opinion set forth below.
In addition, we have relied upon certain statements, representations and
covenants made by Old World Access, New World Access, Merger Sub and Telco
Systems, including representations and covenants set forth in letters from New
World Access and Telco Systems dated the date hereof (the "Tax Certificates"),
and we have assumed that the Tax Certificates will be complete and accurate, and
will be re-executed by appropriate officers of New World Access and Telco
Systems, as of the Effective Time.
 
     In rendering our opinion set forth below, we have assumed that (i) the
Merger will be consummated in accordance with the terms of the Merger Agreement
and as described in the Registration Statement and that none of the terms and
conditions contained therein will be waived or modified in any respect prior to
the Effective Time and (ii) the Registration Statement, the Merger Agreement and
the Tax Certificates reflect all the material facts relating to the Merger, New
World Access, Old World Access, Merger Sub, and Telco Systems. Our opinion is
conditioned upon, among other things, the initial and continuing accuracy and
completeness of the facts, information, covenants, representations and
warranties made by Old World Access, New World Access, Merger Sub and Telco
Systems (including, without limitation, those set forth in the Merger Agreement
and the Tax Certificates). Any material change or inaccuracy in the facts
referred to, set forth or assumed herein, in the Registration Statement, the
Merger Agreement or in the Tax Certificates (giving effect to all events
occurring subsequent to the Effective Time) may affect the conclusions stated
herein.
 
     We have also assumed the genuineness of all signatures, the legal capacity
of all natural persons, the authenticity of all documents submitted to us as
originals, the conformity to original documents of all documents submitted to us
as certified or photostatic copies and the authenticity of the originals of such
documents.
 
     In rendering our opinion set forth below, we have considered applicable
provisions of the Internal Revenue Code of 1986, as amended (the "Code"),
Treasury regulations promulgated thereunder (the "Regulations"), pertinent
judicial authorities, rulings of the Internal Revenue Service and such other
<PAGE>   2

authorities as we have considered relevant. It should be noted that such laws,
the Code, the Regulations, judicial decisions and administrative interpretations
are subject to change at any time and, in some circumstances, with retroactive
effect. Additionally, there can be no assurance that contrary positions will not
be taken by the Internal Revenue Service. A material change in any of the
authorities upon which our opinion is based could affect our conclusions herein.
 
     Based solely upon and subject to the foregoing and the other limitations,
qualifications, exceptions and assumptions set forth herein, we are of the
opinion that, under current law:
 
          (1) The Merger will qualify as a "reorganization" for U.S. federal
     income tax purposes under Section 368(a) of the Code and Telco Systems, New
     World Access and Merger Sub will each be a party to such "reorganization"
     within the meaning of Section 368(b) of the Code;
 
          (2) The statements in the Joint Proxy Statement/Prospectus, which
     forms part of the Registration Statement (the "Joint Proxy
     Statement/Prospectus"), under the caption "The Merger -- Federal Income Tax
     Consequences," insofar as such statements purport to summarize the material
     federal income tax consequences of the Merger to Telco Systems and the
     holders of Telco Systems Common Stock under the laws of the United States
     referred to therein and subject to the qualifications referred to therein,
     fairly summarize such consequences in all material respects.
 
     Except as expressly set forth above, we express no other opinion,
including, without limitation, any opinion as to whether any events subsequent
to the Effective Time will be viewed as part of the plan of reorganization for
U.S. federal income tax purposes and the effect, if any, of such events on our
conclusions herein.
 
     This opinion is for your benefit and is not to be used, circulated, quoted
or otherwise referred to for any purpose, except we consent to the filing of
this opinion as an Exhibit to the Registration Statement and to the use of our
name in the Joint Proxy Statement/Prospectus under the captions "The
Merger -- Federal Income Tax Consequences" and "Legal Matters." In giving such
consent, we do not thereby admit that we are in the category of persons whose
consent is required under Section 7 of the Securities Act or the rules and
regulations of the Securities and Exchange Commission thereunder.
 
     The opinion expressed herein is as of the date hereof, and we disclaim any
undertaking to advise you of changes of facts stated or assumed herein or any
subsequent changes in applicable law.
 
                                   Very truly yours,
 
                                   /s/ SKADDEN, ARPS, SLATE, MEAGHER & FLOM LLP

     Re:  Federal Income Tax Consequences of the Proposed Merger of
        Telco Systems, Inc. with and into Tail Acquisition Corporation
 
Gentlemen:
 
     We have acted as counsel to World Access, Inc. (formerly known as WAXS INC.
(the "Company")) in connection with the proposed merger (the "Merger") of Telco
Systems, Inc., a Delaware corporation ("Telco Systems"), with and into Tail
Acquisition Corporation ("Merger Sub"), a Delaware corporation and wholly-owned
subsidiary of the Company, pursuant to that certain Agreement and Plan of Merger
and Reorganization dated as of June 4, 1998, as amended by that certain First
Amendment thereto dated as of October 27, 1998, by and among WA Telcom Products
Co., Inc. (formerly known as World Access, Inc.), the Company, Merger Sub and
Telco Systems (as so amended, the "Merger Agreement"). In our capacity as
counsel to the Company and as provided in the Merger Agreement, we have been
requested to render our opinion regarding certain of the federal income tax
consequences of the Merger.
 
     We understand that this opinion will be filed as an exhibit to the
Registration Statement on Form S-4 (the "Registration Statement") that will be
filed by the Company with the Securities and Exchange Commission relating to the
securities that will be issued by the Company pursuant to the Merger Agreement
and that this opinion will be referred to in the Joint Proxy
Statement/Prospectus that will be a part of the Registration Statement,
including references to this firm in the section thereof entitled "THE MERGER --
Federal Income Tax Consequences." We hereby specifically consent to such uses of
and references to this opinion.
 
     All terms used herein without definition shall have the respective meanings
specified in the Merger Agreement and, unless otherwise indicated, all section
references herein are to the Internal Revenue Code of 1986, as amended.
 
                            INFORMATION RELIED UPON
 
     In rendering this opinion, we have examined such documents as we have
deemed appropriate, including the Merger Agreement and the Registration
Statement. In the course of such examination, we have assumed, with your
consent, that all documents submitted to us as photocopies faithfully reproduce
the originals thereof, that all such originals are authentic, that all such
documents have been or will be duly executed to the extent required, and that
all statements set forth in such documents are accurate. We have also obtained
such additional information and representations as we have deemed relevant and
necessary through consultations with various representatives of the Company and
Telco Systems. In addition, we have obtained written certificates from the
managements of the Company and Telco Systems to verify certain relevant facts
that have been represented to us or that we have assumed in rendering this
opinion. With your consent, we have assumed that the representations made in
such certificates are true on the date hereof and will be true at the Effective
Time.
<PAGE>   2
 
                                    OPINION
 
     Based upon the foregoing, it is our opinion that:
 
          1. The Merger will qualify as a "reorganization" within the meaning of
     Section 368 of the Code, and each of the Company, Merger Sub, and Telco
     Systems will be "a party to a reorganization" within the meaning of Section
     368(b).
 
          2. No gain or loss will be recognized by the Company, Merger Sub or
     Telco Systems in the Merger.
 
     The opinion expressed herein is based upon existing statutory, regulatory,
and judicial authority, any of which may be changed at any time with retroactive
effect. In addition, such opinion is based solely on the documents that we have
examined, the additional information that we have obtained and the
representations that have been made to us, and this opinion cannot be relied
upon if any of the facts contained in such documents or in such additional
information is, or later becomes, inaccurate or if any of the representations
made to us is, or later becomes, inaccurate.
 
     The opinion expressed herein is limited to the tax matters specifically
covered thereby, and we have not been asked to address, nor have we addressed,
any other tax consequences of the Merger.
 
                                          Very truly yours,
