(1) This registration statement relates to securities of the Registrant issuable
    to holders of capital stock of NACT Telecommunications, Inc., a Delaware
    corporation ("NACT"), in the proposed merger of a wholly-owned subsidiary of
    the Registrant with and into NACT (the "NACT Merger"), and to holders of
    capital stock of World Access, Inc., a Delaware corporation ("World
    Access"), in the proposed merger of a wholly-owned subsidiary of the
    Registrant with and into World Access (the "World Access Merger").
(2) Based upon the number of shares of capital stock of NACT and World Access
    presently outstanding or otherwise expected to be issued on or before the
    closing of the mergers and entitled to receive the merger consideration
    pursuant to the NACT Merger and the World Access Merger.
(3) Pursuant to Rules 457(f)(i) and 457(c) under the Securities Act of 1933, as
    amended, and solely for purposes of calculating the registration fee, the
    registration fee was computed on the basis of the average of the high and
    low prices of the common stock of NACT on The Nasdaq National Market and the
    average of the high and low prices of the common stock of World Access on
    The Nasdaq National Market, in each case on October 5, 1998.
(4) The registration fee of $135,355 was calculated pursuant to 457(f) under the
    Securities Act as follows: $295 per $1,000,000 (or fraction thereof) of the
    proposed maximum aggregate offering price. A fee of $12,738 was paid on
    April 28, 1998 pursuant to Section 14(g) of the Securities Exchange Act of
    1934, as amended (the "Exchange Act"), in connection with the filing of the
    preliminary materials by World Access and NACT. Pursuant to 457(b) under the
    Securities Act, the registration fee payable herewith has been reduced by
    $12,738, the amount previously paid upon filing of such preliminary
    materials. Accordingly, an additional fee of $122,617 is required to be paid
    with the filing of this Registration Statement.
                             ---------------------
 
     THE REGISTRANT HEREBY AMENDS THIS REGISTRATION STATEMENT ON SUCH DATE OR
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 SECURITIES ACT OF 1933 OR UNTIL THE REGISTRATION STATEMENT SHALL BECOME
EFFECTIVE ON SUCH DATE AS THE COMMISSION, ACTING PURSUANT TO SAID SECTION 8(A),
MAY DETERMINE.

                               PROVO, UTAH 84604
Dear Stockholder:
 
     You are cordially invited to attend a special meeting of stockholders (the
"NACT Special Meeting") of NACT Telecommunications, Inc. ("NACT") to be held at
NACT's principal offices located at 191 West 5200 North, Provo, Utah 84604 on
October 28, 1998, at 10:00 a.m., local time.
 
     At the NACT Special Meeting you will be asked to consider and vote upon a
proposal (the "NACT Merger Proposal") to approve the Agreement and Plan of
Merger and Reorganization, dated as of February 24, 1998, as amended (as so
amended, the "NACT Merger Agreement"), among WAXS INC. ("Holdco"), a Delaware
corporation and a wholly-owned subsidiary of World Access, Inc., a Delaware
corporation ("World Access"), World Access, WAXS Acquisition Corp., a Delaware
corporation and a wholly-owned subsidiary of Holdco ("WAXS Merger Sub"), NACT
and NACT Acquisition Corp., a Delaware corporation and a wholly-owned subsidiary
of Holdco ("NACT Merger Sub"). The NACT Merger Agreement provides, among other
things, for the following transactions:
 
          (i) the merger of NACT Merger Sub with and into NACT (the "NACT
     Merger"), in which each share of NACT common stock, $.01 par value per
     share (the "NACT Common Stock"), outstanding immediately prior to the
     effective time of the NACT Merger, other than shares of NACT Common Stock
     held directly or indirectly by World Access or Holdco or in the treasury of
     NACT, will be converted into the right to receive a number of shares of the
     common stock, $.01 par value per share, of Holdco (the "Holdco Common
     Stock") equal to the quotient of (x) $17.50 divided by (y) the average of
     the daily closing price of the shares of common stock, $.01 par value per
     share, of World Access (the "World Access Common Stock") as reported on The
     Nasdaq National Market on each of the twenty consecutive trading days
     ending with the third trading day immediately preceding the effective time
     of the NACT Merger, subject to adjustment as described in the accompanying
     Prospectus/Information Statement; and
 
          (ii) the merger of WAXS Merger Sub with and into World Access (the
     "World Access Merger" and, together with the NACT Merger, the "Mergers"),
     in which each share of World Access Common Stock outstanding immediately
     prior to the effective time of the World Access Merger, other than shares
     held directly or indirectly by World Access, will be converted into one
     share of Holdco Common Stock.
 
     The transactions contemplated by the NACT Merger Agreement are referred to
herein as the "NACT Transaction." As a result of the NACT Transaction, each of
World Access and NACT will become a wholly-owned subsidiary of Holdco, which
shall be renamed "World Access, Inc." immediately following the consummation of
the Mergers.
 
     World Access currently holds 5,468,712 shares of NACT Common Stock,
representing approximately 67.2% of the outstanding shares of NACT Common Stock
entitled to vote at the NACT Special Meeting, thereby assuring approval of the
NACT Merger Proposal.
 
     The accompanying Prospectus/Information Statement explains in detail the
terms of the Mergers and the Holdco Common Stock to be issued in connection
therewith. ALTHOUGH YOU ARE NOT BEING ASKED FOR A PROXY AND ARE REQUESTED NOT TO
SEND IN A PROXY, PLEASE READ THE ACCOMPANYING PROSPECTUS/INFORMATION STATEMENT
CAREFULLY.
 
     THE BOARD OF DIRECTORS OF NACT HAS UNANIMOUSLY APPROVED AND ADOPTED THE
NACT MERGER AGREEMENT AND APPROVED THE NACT MERGER.
 
                                          Sincerely,

                         NACT TELECOMMUNICATIONS, INC.
                             INFORMATION STATEMENT

                             ---------------------
 
    This Prospectus/Information Statement is being furnished to stockholders of
NACT Telecommunications, Inc., a Delaware corporation ("NACT"), in connection
with a special meeting of stockholders (the "NACT Special Meeting") of NACT to
be held at NACT's principal offices located at 191 West 5200 North, Provo, Utah
84604, on October 28, 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 NACT. STOCKHOLDERS OF
NACT ARE NOT BEING ASKED FOR A PROXY AND ARE REQUESTED NOT TO SEND NACT A PROXY.
 
    This Prospectus/Information Statement also constitutes a prospectus of WAXS,
INC., a Delaware corporation ("Holdco"), with respect to shares of common stock,
par value $.01 per share, of Holdco (the "Holdco Common Stock") to be issued to
the stockholders of World Access and NACT in connection with the Agreement and
Plan of Merger and Reorganization, dated as of February 24, 1998, as amended (as
so amended, the "NACT Merger Agreement"), among Holdco, a wholly-owned
subsidiary of World Access, Inc., a Delaware corporation ("World Access"), World
Access, WAXS Acquisition Corp., a Delaware corporation and a wholly-owned
subsidiary of Holdco ("WAXS Merger Sub"), NACT and NACT Acquisition Corp., a
Delaware corporation and a wholly-owned subsidiary of Holdco ("NACT Merger
Sub").
 
    The NACT Merger Agreement provides, among other things, for the following
transactions:
 
        (i) the merger of NACT Merger Sub with and into NACT (the "NACT
    Merger"), in which each share of NACT common stock, $.01 par value per share
    (the "NACT Common Stock"), outstanding immediately prior to the effective
    time of the NACT Merger, other than shares of NACT Common Stock held
    directly or indirectly by World Access or Holdco or in the treasury of NACT,
    will be converted into the right to receive that number of shares of the
    common stock, $.01 par value per share, of Holdco (the "Holdco Common
    Stock") equal to the quotient of (x) $17.50 divided by (y) the average of
    the daily closing price of the shares of common stock, $.01 par value per
    share, of World Access (the "World Access Common Stock") as reported on The
    Nasdaq National Market ("Nasdaq") on each of the twenty consecutive trading
    days ending with the third trading day immediately preceding the effective
    time of the NACT Merger (the "World Access Average Closing Price"), unless
    the World Access Average Closing Price exceeds $25.52 per share, in which
    event each such outstanding share of NACT Common Stock will be converted
    into 0.6857 shares of Holdco Common Stock (as adjusted, if at all, the "NACT
    Exchange Ratio"); provided, however, that if the World Access Average
    Closing Price is less than $20.88 per share, then World Access may terminate
    the NACT Merger Agreement; and
 
        (ii) the merger of WAXS Merger Sub with and into World Access (the
    "World Access Merger" and, together with the NACT Merger, the "Mergers"), in
    which each share of World Access Common Stock outstanding immediately prior
    to the effective time of the World Access Merger, other than shares held
    directly or indirectly by World Access, will be converted into one share of
    Holdco Common Stock.
 
    The transactions contemplated by the NACT Merger Agreement are referred to
herein as the "NACT Transaction." As a result of the NACT Transaction, each of
World Access and NACT will become a wholly-owned subsidiary of Holdco, which
shall be renamed "World Access, Inc." immediately following consummation of the
Mergers.
 
    The proposed NACT Merger is contingent upon, among other things, the
approval of the holders of the requisite number of shares of NACT Common Stock,
all as described in this Prospectus/Information Statement. The proposed NACT
Merger will be consummated as soon as practicable after such approvals are
obtained and the other conditions to the NACT Merger are satisfied or waived.
The consummation of the World Access Merger, which is not subject to the
approval of the World Access stockholders, is a condition to the NACT Merger.
 
    World Access currently holds 5,468,712 shares of NACT Common Stock,
representing approximately 67.2% of the outstanding shares of NACT Common Stock
entitled to vote at the NACT Special Meeting, thereby assuring approval of the
NACT Merger Proposal.
 
    Upon consummation of the Mergers, the current NACT stockholders (other than
World Access) will own approximately 7.4% of the then-outstanding shares of
Holdco Common Stock.
 
    The Mergers are contingent upon the receipt of any required governmental
approvals and the satisfaction of certain customary conditions. The Mergers will
be consummated as soon as practicable after such approvals are obtained and the
other conditions are satisfied or waived.
 
    On October 5, 1998, the last reported sale prices on Nasdaq of World Access
Common Stock and NACT Common Stock were $16 1/2 and $12 1/8, respectively. On
February 24, 1998, the last full trading day prior to the public announcement of
the execution of the NACT Merger Agreement, the last reported sale prices on
Nasdaq of World Access Common Stock and NACT Common Stock were $23 7/8 and
$16 5/8, respectively.
 
    All information contained in this Prospectus/Information Statement relating

which World Access paid to GST USA cash in the amount of $59,662,956 and
delivered to GST USA 1,429,907 shares of World Access Common Stock.
 
     Pursuant to the NACT Stock Purchase Agreement, W. Gordon Blankstein,
Stephen Irwin, Robert L. Olson and Clifford V. Sander resigned as directors of
NACT effective upon consummation of the NACT Stock Purchase, and Steven A. Odom
and Hensley E. West, who are directors and executive officers of World Access,
and Mark A. Gergel and Scott N. Madigan, who are executive officers of World
Access, were appointed as directors of NACT to fill the vacancies created by the
resignations of Messrs. Blankstein, Irwin, Olson and Sander.
 
     Prior to entering into the NACT Stock Purchase Agreement, World Access
acquired 355,000 shares of NACT Common Stock in open-market transactions from
November 12, 1997 to December 9, 1997, as a result of which World Access
currently owns directly approximately 67.2% of the outstanding shares of NACT
Common Stock.
 
THE NACT SPECIAL MEETING
 
     Date and Place of the Meeting.  The special meeting of stockholders of NACT
(the "NACT Special Meeting") will be held at NACT's principal offices located at
191 West 5200 North, Provo, Utah 84604, on October 28, 1998, at 10:00 a.m.,
local time.
 
     Stockholders Entitled to Vote.  The record date for determination of
holders of NACT Common Stock entitled to vote at the NACT Special Meeting is
September 22, 1998 (the "NACT Record Date"). As of the close of business on the
NACT Record Date, 8,133,830 shares of NACT Common Stock were outstanding, held
by approximately 16 holders of record. Only holders of record of NACT Common
Stock as of the close of business on the NACT Record Date are entitled to notice
of and to vote at the NACT Special Meeting and any adjournments or postponements
thereof.
 
     Purpose of the Meeting.  The purpose of the NACT Special Meeting is (i) to
consider and vote upon the NACT Merger Proposal and (ii) to transact such other
business as may properly come before the NACT Special Meeting or any
adjournments or postponements thereof.
 
     Vote Required.  The approval of the NACT Merger Agreement and the NACT
Merger will require the affirmative vote of a majority of the outstanding shares
of NACT Common Stock. See "The NACT Special Meeting -- Voting; Vote Required."
 
     Shares of NACT Common Stock that are voted "FOR," "AGAINST" or "WITHHELD"
at the NACT 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 NACT Common Stock present in person at the NACT 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
 
                                        2
<PAGE>   13
 
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
NACT Merger Agreement and the NACT Merger, which approval will require the
affirmative vote of a majority of the outstanding shares of NACT Common Stock.
 
     Security Ownership by Certain Beneficial Owners and Management.  As of the
close of business on the NACT Record Date, directors and executive officers of
NACT and their respective affiliates may be deemed to be the beneficial owners
of shares of NACT Common Stock representing approximately 67.2% of the
outstanding voting power of NACT. Each of the directors and executive officers
of NACT has indicated that such person intends to vote or direct the vote of all
the shares of NACT Common Stock over which such person has voting control in
favor of the NACT Merger Agreement and the NACT Merger. In addition, World
Access currently owns 5,468,712 shares of NACT Common Stock, representing
approximately 67.2% of the outstanding shares of NACT Common Stock. AS A RESULT,
WORLD ACCESS HAS THE RIGHT TO VOTE SUFFICIENT SHARES TO APPROVE THE NACT MERGER
AGREEMENT AND THE NACT MERGER AT THE NACT SPECIAL MEETING WITHOUT THE
AFFIRMATIVE VOTE OF ANY OTHER NACT STOCKHOLDER, THEREBY ASSURING THE APPROVAL OF
THE NACT MERGER AGREEMENT AND THE NACT MERGER.
 
     STOCKHOLDERS OF NACT ARE NOT BEING ASKED FOR A PROXY AND ARE REQUESTED NOT
TO SEND A PROXY.
 
RECOMMENDATION OF NACT'S BOARD OF DIRECTORS
 
     THE BOARD OF DIRECTORS OF NACT HAS UNANIMOUSLY APPROVED AND ADOPTED THE
NACT MERGER AGREEMENT AND APPROVED THE NACT MERGER AND UNANIMOUSLY RECOMMENDS
THAT THE STOCKHOLDERS OF NACT VOTE FOR THE APPROVAL AND ADOPTION OF THE NACT
MERGER AGREEMENT AND APPROVAL OF THE NACT MERGER. See "The NACT
Transaction -- NACT's Reasons for the NACT Merger; Recommendation of NACT's
Board of Directors."
 
OPINION OF NACT'S FINANCIAL ADVISOR
 
     In making its recommendation with respect to the NACT Merger, the board of
directors of NACT considered, among other things, the written opinion, dated as
of February 24, 1998, of NationsBanc Montgomery Securities LLC ("NationsBanc
Montgomery"), NACT's financial advisor, to the effect that, as of such date and
based upon and subject to the assumptions, limitations and qualifications set
forth in such opinion, the NACT Exchange Ratio was fair, from a financial point
of view, to the holders of NACT Common Stock. A copy of such opinion is attached
to this Prospectus/Information Statement as Appendix B. NationsBanc Montgomery's
opinion, which sets forth the assumptions made, procedures followed and matters
considered by NationsBanc Montgomery, as well as the scope of NationsBanc
Montgomery's review, should be read carefully in its entirety. See "The NACT
Merger -- Opinion of NACT's Financial Advisor."
 
THE NACT TRANSACTION
 
     Purpose of the NACT Transaction.  The purpose of the NACT Transaction is to
combine World Access and NACT.
 
     Effect of the NACT Transaction Upon World Access.  Upon consummation of the
Mergers, (i) WAXS Merger Sub will be merged into World Access, and (ii) each
outstanding share of World Access Common Stock, other than shares held directly
or indirectly by World Access, will be converted into one share of Holdco Common
Stock and, upon such conversion, will be canceled and retired and will cease to
exist. As a result of the NACT Transaction, World Access will become a wholly
owned subsidiary of Holdco.
 
     Effect of the NACT Transaction Upon NACT.  Upon consummation of the
Mergers, (i) NACT Merger Sub will be merged into NACT, (ii) each outstanding
share of NACT Common Stock, other than shares held directly or indirectly by
World Access or Holdco or in the treasury of NACT, will be converted into the
right to receive shares of Holdco Common Stock based upon the NACT Exchange
Ratio and, upon such
 
                                        3
<PAGE>   14
 
conversion, will be canceled and retired and will cease to exist, (iii) all
shares of NACT Common Stock held directly or indirectly by World Access or
Holdco will remain outstanding and unaffected by the NACT Merger, and (iv) each
of the issued and outstanding shares of the capital stock of NACT Merger Sub
will be converted into one share of NACT Common Stock. As a result of the NACT
Transaction, NACT will become a wholly owned subsidiary of Holdco. Because the
value of the shares of Holdco Common Stock that holders of NACT Common Stock
will receive in the NACT Merger is fixed, subject to adjustment under certain
circumstances as described herein, and because the market price of World Access
Common Stock is subject to fluctuation, the number of shares of Holdco Common
Stock that holders of NACT Common Stock will receive in the NACT Merger may
increase or decrease prior to the NACT Effective Time (as hereinafter defined).
Holders of NACT Common Stock are advised to obtain current market quotations for
World Access Common Stock.
 
     The following table sets forth the number of shares of Holdco Common Stock
into which each share of NACT Common Stock would be converted upon consummation
of the NACT Merger at each of the hypothetical World Access Average Closing
Prices set forth below.

 * If the World Access Average Closing Price is below $20.88 per share, then
   World Access may terminate the NACT Merger Agreement. If World Access does
   not elect to so terminate the NACT Merger Agreement, then the NACT Exchange
   Ratio will be equal to the quotient of (x) $17.50 divided by (y) the World
   Access Average Closing Price.
** If the World Access Average Closing Price is above $25.51 per share, then the
   number of shares of Holdco Common Stock into which each share of NACT Common
   Stock would be converted upon consummation of the NACT Merger would be fixed
   at .6857.
 
     Treatment of Options.  Upon consummation of the Mergers, each
then-outstanding option to purchase shares of NACT Common Stock will be assumed
by Holdco and converted into an option to purchase shares of Holdco Common
Stock. Following the consummation of the NACT Merger, each such option will
continue to have, and will be subject to, the same terms and conditions as in
effect immediately prior to the consummation of the NACT Merger, except that
each such option will be exercisable for that number of shares of Holdco Common
Stock equal to the product of the number of shares of NACT Common Stock for
which such option was exercisable immediately prior to the consummation of the
NACT Merger multiplied by the NACT Exchange Ratio, and the exercise price per
share subject to such option will be equal to the aggregate exercise price of
such option immediately prior to the consummation of the NACT Merger divided by
the number of shares of Holdco Common Stock for which such option will be
exercisable immediately after the consummation of the NACT Merger. There were no
options to purchase NACT Common Stock outstanding as of October 5, 1998.
 
     In addition, upon consummation of the World Access Merger, each option to
purchase shares of World Access Common Stock will be assumed by Holdco and
converted into an option to purchase shares of Holdco Common Stock on the same
terms and conditions as in effect immediately prior to the consummation of the
World Access Merger. See "The NACT Merger Agreement -- Treatment of Options and
Warrants."
 
     Treatment of Convertible Debt and Warrants.  Upon consummation of the World
Access Merger, Holdco will irrevocably and unconditionally guarantee all of
World Access' obligations with respect to the
 
                                        4
<PAGE>   15
 
4.5% Convertible Subordinated Notes due 2002 of World Access currently
outstanding (the "World Access Notes") and the World Access Notes thereupon will
become convertible into shares of Holdco Common Stock at the rate of one share
of Holdco Common Stock for each share of World Access Common Stock into which
they were convertible immediately prior to the consummation of the World Access
Merger. See "The NACT Transaction -- Effect of NACT Transaction on Certain
Outstanding World Access Convertible Securities."
 
     Upon consummation of the World Access Merger, each warrant to purchase
World Access Common Stock will become exercisable for Holdco Common Stock at the
same rate, for the same price and on the same terms as in effect immediately
prior to the consummation of the World Access Merger. See "The NACT Merger
Agreement -- Treatment of Options and Warrants."
 
     Interests of Certain Persons.  In considering the recommendations of the
NACT board of directors with respect to the NACT Merger, NACT stockholders
should be aware that certain directors and executive officers of NACT have
interests in the NACT Merger that may be in addition to the interests of other
holders of NACT Common Stock. See "The NACT Transaction -- Interests of Certain
Persons in the NACT Transaction."
 
     Appraisal and Dissenters' Rights.  Holders of NACT Common Stock are not
entitled to appraisal or dissenters' rights in connection with the NACT Merger.
See "The NACT Transaction -- Appraisal and Dissenters' Rights."
 
     Federal Income Tax Consequences.  It is a condition to the consummation of
the NACT Merger that NACT receive an opinion from Van Cott, Bagley, Cornwall &
McCarthy, counsel to NACT, reaffirming, as of the date of consummation of the
Mergers, the opinion described in this Prospectus/Information Statement to the
effect that the NACT Merger will be treated for U.S. Federal income tax purposes
as a transfer of property governed by Section 351 of the Internal Revenue Code
of 1986, as amended (the "Code"). Accordingly, except as described below and
subject to the qualifications set forth under "The NACT Transaction -- Federal
Income Tax Consequences -- NACT Merger," it is the opinion of Van Cott, Bagley,
Cornwall & McCarthy that no gain or loss will be recognized pursuant to the NACT
Merger by (i) Holdco, (ii) NACT or (iii) a holder of NACT Common Stock whose
shares of NACT Common Stock are converted into the right to receive shares of
Holdco Common Stock. Notwithstanding the foregoing, a holder of NACT Common
Stock may recognize gain or loss by reason of cash received in lieu of
fractional shares or upon the proper exercise of dissenters' rights. See "The
NACT Transaction -- Federal Income Tax Consequences -- NACT Merger."
 
     Accounting Treatment.  The NACT Transaction will be accounted for by Holdco
under the purchase method of accounting for business combinations. See "The NACT
Transaction -- Accounting Treatment."
 
RECENT WORLD ACCESS DEVELOPMENTS
 
     Resurgens Transaction.  On May 12, 1998, World Access announced that it had
entered into (i) an Agreement and Plan of Merger and Reorganization (the
"Resurgens Merger Agreement") with Cherry Communications Incorporated (d/b/a
Resurgens Communications Group) ("RCG"), which is currently operating as a
debtor in possession under Chapter 11 of the Bankruptcy Code, pursuant to which
Holdco has 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
Communications U.K. Limited ("Cherry U.K.") pursuant to which Holdco has agreed
to acquire Cherry U.K. in a share exchange transaction (the "Exchange"). RCG and
Cherry U.K. are sometimes collectively referred to herein as "Resurgens."
 
     In connection with the RCG Merger, the creditors of RCG will receive an
aggregate of 9,375,000 shares of Holdco Common Stock. Of the shares of Holdco
Common Stock to be issued to the RCG creditors, two-thirds will be held in
escrow and will be released to the RCG creditors over the two and one-half years
following the consummation of the RCG Merger subject to the attainment of
certain performance criteria for the combined business of World Access and
Resurgens.
 
                                        5
<PAGE>   16
 
     In connection with the Exchange, the Shareholder will receive an aggregate
of 1,875,000 shares of Holdco Common Stock, of which one-third will be issued to
the Shareholder at closing and the remaining two-thirds will be issued and held
in escrow and will be released to the Shareholder over the two and one-half year
period following the consummation of the Exchange subject to the attainment of
certain performance criteria for the combined business of World Access and
Resurgens. The Exchange Agreement provides, however, that the number of shares
of Holdco Common Stock to be received by the Shareholder will be reduced to the
extent that Holdco is required to convert options to acquire shares of Cherry
U.K. capital stock, which options may only be granted with the permission of
Holdco, into options to acquire Holdco Common Stock.
 
     Each of the RCG Merger and the Exchange is subject to the satisfaction of
certain conditions customary in similar transactions, including the approval of
the stockholders of Holdco and the consummation of the Holding Company
Reorganization. The consummation of the RCG Merger is a condition to the
consummation of the Exchange, and the Exchange is a condition to the
consummation of the RCG Merger. The RCG Merger and the 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.
 
     Holdco intends to submit the Resurgens Transaction to its stockholders for
approval promptly following the consummation of the NACT Transaction. Since the
NACT stockholders will not become stockholders of Holdco prior to the record
date for a meeting of Holdco's stockholders to consider the Resurgens
Transaction, the current NACT stockholders will not be entitled to vote upon the
Resurgens Transaction.
 
     Upon the consummation of the Resurgens Transaction, the current NACT
stockholders will own approximately 5.1% of the outstanding shares of Holdco
Common Stock.
 
     Telco Merger.  On June 4, 1998, World Access announced that it had entered
into an Agreement and Plan of Merger and Reorganization (the "Telco Merger
Agreement") with Holdco, Tail Acquisition Corporation, a wholly-owned subsidiary
of Holdco ("Telco Merger Sub"), and Telco Systems, Inc. ("Telco") pursuant to
which, among other things, Telco Merger Sub has agreed to merge with and into
Telco (the "Telco Merger").
 
     As a result of the Telco Merger, each outstanding share of Telco common
stock, $.01 par value per share ("Telco Common Stock"), will be converted into
the right to receive that number of shares of (i) World Access Common Stock or
(ii) if the NACT Transaction shall have been consummated on or before the time
of the Telco Merger, Holdco Common Stock (in either case, the "Telco Merger
Common Stock") equal to the quotient of $17.00 divided by the average daily
closing price of World Access Common Stock as reported on Nasdaq for each of the
twenty consecutive trading days ending on the second business day prior to the
date of the Telco Merger (the "Telco Average Closing Price"), provided that if
the Telco Average Closing Price is more than $36.00 per share, then each share
of Telco Common Stock will be converted into .4722 shares of Telco Merger Common
Stock and if the Telco Average Closing Price is less than $29.00 per share, then
each share of Telco Common Stock will be converted into .5862 shares of Telco
Merger Common Stock.
 
     The consummation of the Telco Merger is subject to (i) the approval by the
respective stockholders of World Access (or Holdco, as the case may be) and
Telco, (ii) the approval by the stockholders of World Access or Holdco (as the
case may be) of an increase in the authorized shares of common stock of such
corporation, and (iii) the satisfaction or waiver of other customary conditions.
 
     Telco is a manufacturer of broadband transmission products, network access
products and bandwidth optimization products for network services. It had net
sales of approximately $117.8 million for its fiscal year ended August 31, 1997
and $81.6 million for the nine months ended May 31, 1998 and incurred a net loss
of $1.1 million for the year ended August 31, 1997 and $2.9 million for the nine
months ended May 31, 1998.
 
                                        6
<PAGE>   17
 
     Holdco intends to submit the Telco Merger to its stockholders for approval
promptly following the consummation of the NACT Transaction. Since the NACT
stockholders will not become stockholders of Holdco prior to the record date for
a meeting of Holdco's stockholders to consider the Telco Merger, the current
NACT stockholders will not be entitled to vote upon the Telco Merger.
 
     Upon the consummation of the Telco Merger, the current NACT stockholders
will own approximately 5.9% of the outstanding shares of Holdco Common Stock
(and 4.3% upon the consummation of both the Resurgens Transaction and the Telco
Merger).

(1) Includes the results of operations for the following businesses from their
    respective dates of acquisition: 67.2% interest in NACT -- February 27,
    1998; ATI -- January 29, 1998; Galaxy -- July 1, 1997; CIS -- January 1,
    1997; Sunrise -- January 1, 1996; Westec -- October 2, 1995; and AIT -- May
    17, 1995. On a pro forma unaudited basis, as if the acquisition of the 67.2%
    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
    acquisitions of ATI and a 67.3% interest in NACT. See Note 2 to the
    Consolidated Financial Statements in the World Access June 30 Form 10-Q. The
    Company expects to record an additional in-process research and development
    charge of approximately $22.0 million in the third quarter of 1998 in
    connection with the acquisition of the remaining 32.8% of NACT.
(3) Special charges in the first six months 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 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 in the World Access June 30 Form
    10-Q. Special charges in 1995 resulted primarily from a write-down of test
    equipment and related tooling used in World Access' analog repair
    operations.
(4) World Access recorded no income tax expense during 1995 and 1996 due to net
    losses realized and the availability of federal income tax net operating
    loss carryforwards. See "Management's Discussion and Analysis of Financial
    Condition and Results of Operations" and Note K to the Consolidated
    Financial Statements in the World Access Form 10-K.
(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 Consolidated
    Financial Statements in the World Access Form 10-K.
(6) In October 1997, World Access sold $115.0 million of convertible
    subordinated notes. See Note G to the Consolidated Financial Statements in
    the World Access Form 10-K.

                                  RISK FACTORS
 
     Holders of NACT Common Stock, in evaluating whether to approve the NACT
Merger and thereby become holders of Holdco Common Stock, should carefully
consider the following risk factors, in addition to the other information
included and incorporated by reference in this Prospectus/Information Statement.
Other than statements of historical fact, statements contained in this
Prospectus/Information Statement, including statements as to the benefits
expected to be realized as a result of the NACT Merger and the World Access
Merger and as to future financial performance, constitute forward-looking
statements. Holdco's actual results may differ significantly from the results
discussed in the forward-looking statements contained in this
Prospectus/Information Statement. Factors that might cause such a difference
include, but are not limited to, those discussed below. Holders of NACT Common
Stock are cautioned not to place undue reliance on the forward-looking
statements contained in this Prospectus/Information Statement, which speak only
as of the date hereof. Neither World Access nor NACT 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.
 
     ACQUISITION RISKS.  An element of Holdco's strategy for the future is
expansion through the acquisition of companies that complement or expand its
existing businesses. As a result, Holdco will continue to evaluate potential
acquisition opportunities, some of which may be material in size or scope.
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 Holdco's operating results, the realization of
acquired intangible assets and the loss of key employees of the acquired
companies. Holdco may issue equity securities and other forms of consideration
in connection with future acquisitions, which could cause dilution to Holdco's
then-existing stockholders. World Access does not currently have any commitments
or agreements with respect to any acquisitions other than the NACT Merger
Agreement, the RCG Merger Agreement, the Exchange Agreement and the Telco Merger
Agreement. See "Business of World Access." There can be no assurance that
suitable acquisition candidates will be found at prices acceptable to Holdco,
that Holdco will have adequate resources to consummate any acquisition, that
acquisitions can be consummated successfully, or that acquired businesses can be
operated profitably or integrated successfully into Holdco's operations.
 
     INCREASED LEVERAGE.  In connection with the sale of the World Access Notes,
World Access incurred approximately $115.0 million in additional indebtedness,
which 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. The degree to which
World Access is leveraged could adversely affect its or Holdco's ability to
obtain additional financing for working capital, acquisitions or other purposes
and could make it more vulnerable to economic downturns and competitive
pressures. World Access' increased leverage could also adversely affect its or
Holdco's 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 or Holdco could be forced to reduce other
expenditures and forego potential acquisitions to be able to meet such
requirements.
 
     HOLDING COMPANY RISKS.  Holdco is expected to be a holding company. As a
holding company without significant income from operations, Holdco will be
dependent upon the income from its operating subsidiaries to meet its operating
expenses. If Holdco's operating subsidiaries are unable to pay dividends or
otherwise distribute amounts to Holdco sufficient to cover its operating
expenses, then Holdco may be subject to liquidity problems, even if, on a
consolidated basis, its operating subsidiaries are profitable.
 
     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.
World Access' success 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 World Access' or Holdco's
management is unable to manage such growth effectively, the quality of World
Access' or Holdco's products and services, its ability to retain key personnel
and its business, financial condition and results of operations could be
materially adversely affected.
 
                                       16
<PAGE>   27
 
     COMPETITION.  The segments of the telecommunications industry in which
World Access and NACT operate are intensely competitive. Holdco's ability to
compete will be dependent upon several factors, including price, quality,
product features and timeliness of delivery. Many of World Access' and NACT's
competitors have significantly more extensive engineering, manufacturing,
marketing, financial and technical resources than World Access and NACT. 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.
 
     World Access and NACT 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, may decide to manufacture
telecommunications equipment or to form alliances with other manufacturers. Any
of these developments could result in increased competition for World Access and
NACT, which may have a material adverse effect on Holdco's business, financial
condition and results of operations.
 
     POTENTIAL FLUCTUATIONS IN QUARTERLY OPERATING RESULTS.  World Access' and
NACT's quarterly operating results have varied significantly in the past and are
expected to do so in the future. As World Access and NACT increase the number of
telecommunications product offerings, their future quarterly operating results
may vary significantly depending on factors such as the timing and shipment of
significant orders, new product introductions by them and their competitors,
market acceptance of new and enhanced versions of World Access' and NACT's
products, changes in pricing policies by World Access and NACT and their
competitors, the availability of new technologies, the mix of distribution
channels through which World Access' and NACT's products are sold, the inability
to obtain sufficient supplies of sole or limited source components for World
Access' and NACT's 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 or new product introductions,
each of World Access and NACT may take certain pricing or marketing actions that
could materially and adversely affect their respective quarterly operating
results. Each of World Access' and NACT's expense levels are based, in part, on
their respective expectations as to future sales. If future sales levels are
below expectations, then World Access and NACT may be unable to adjust spending
sufficiently in a timely manner to compensate for the unexpected sales
shortfall. Accordingly, each of World Access and NACT 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. In future quarters, Holdco's operating results may be below the
expectations of public market analysts and investors. In such event, the price
of the Holdco Common Stock would likely be materially adversely affected.
 
     COMPLIANCE WITH GOVERNMENT REGULATIONS AND EVOLVING INDUSTRY
STANDARDS.  World Access' and NACT's products 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
must comply with various regulations promulgated by the Federal Communications
Commission, as well as with standards established by Bell Communications
Research ("BellCore"). Internationally, these products must comply with
standards established by telecommunications authorities in various countries, as
well as with recommendations of the International Telecommunications Union. In
addition, telecommunications service providers require that equipment connected
to their networks comply with their own standards, which may vary from industry
standards. The failure of World Access' or NACT's products to comply, or delays
or costs in achieving compliance, with the various existing and evolving
regulations and industry standards could have a material adverse effect on
Holdco's business, financial condition and results of operations.
 
     Holdco expects that government regulatory policies are likely to continue
to have a major impact on the pricing of both existing and new public network
services and, therefore, are expected to affect demand for such
                                       17
<PAGE>   28
 
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, including World Access' and
NACT's products.
 
     RAPID TECHNOLOGICAL DEVELOPMENT; NEW PRODUCTS; PRODUCT ERRORS.  The market
for World Access' and NACT's products is generally characterized by rapidly
changing technology, evolving industry standards and frequent new product
introductions that can render existing products obsolete or unmarketable.
Holdco'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 new
products that meet changing customer requirements and emerging industry
standards. The failure of Holdco to introduce new products and respond to
industry changes on a timely and cost effective basis could have a material
adverse affect on Holdco's business, financial condition and results of
operations.
 
     The development of new, technologically advanced products is a complex and
uncertain process requiring high levels of innovation and capital, as well as
the accurate anticipation of technological and market trends. Furthermore, the
introduction and marketing of new or enhanced products require World Access and
NACT to manage the transition from existing products in order to minimize
disruption in customer purchasing patterns. There can be no assurance that World
Access or NACT will be successful in developing and marketing, on a timely and
cost-effective basis, new products or product enhancements, that its new
products will adequately address the changing needs of the marketplace, or that
it will successfully manage the transition to new or enhanced products. There
also can be no assurance that World Access or NACT will be able to identify,
develop, manufacture or support new products successfully, that such new
products will gain market acceptance or that World Access or NACT will be able
to respond effectively to technological changes, emerging industry standards or
product announcements by competitors. In addition, World Access and NACT have on
occasion experienced delays in the introduction of product enhancements and new
products. There can be no assurance that in the future World Access and NACT
will be able to introduce product enhancements or new products on a timely and
cost effective basis. The rapid development of new technologies also increases
the risk that current or new competitors could develop products that would
reduce the competitiveness of World Access' or NACT's products. There can be no
assurance that products or technologies developed by others will not render
World Access' or NACT's products or technologies noncompetitive or obsolete.
 
     Products as complex as those offered by World Access and NACT 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 World Access and NACT 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 World Access' or NACT's products,
diversion of development resources, damage to World Access' and NACT's
reputation or increased service or warranty costs, any of which could have a
material adverse effect upon Holdco's business, financial condition and results
of operations.
 
     Furthermore, from time to time, World Access and NACT may announce new
products, capabilities or technologies that have the potential to replace or
shorten the life cycle of their existing product offerings. There can be no
assurance that announcements of product enhancements or new product offerings
will not cause customers to defer purchasing existing World Access or NACT
products or cause resellers to return products to World Access and NACT. Failure
to introduce new products or product enhancements effectively and on a timely
basis, customer delays in purchasing products in anticipation of new product
introductions and any inability of World Access or NACT to respond effectively
to technological changes, emerging industry standards or product announcements
by competitors could have a material adverse effect on Holdco's business,
operating results and financial condition.
 
     DEPENDENCE ON SUPPLIERS.  World Access and NACT purchase substantially all
of their components and other parts from suppliers on a purchase order basis and
do not maintain long-term supply arrangements. Most
 
                                       18
<PAGE>   29
 
of the components used in World Access' and NACT's products and related services
are currently obtained from multiple sources. However, several components,
primarily custom hybrid integrated circuits, are available from a single source.
In addition, the operations of certain of 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 or NACT
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 and NACT on commercially favorable terms.
Failure to obtain products and key components on a timely and cost effective
basis could have a material adverse effect on Holdco's business, financial
condition and results of operations.
 
     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 Holdco's
business, financial condition and results of operations.
 
     In addition, for the year ended August 31, 1997, NYNEX accounted for 33% of
Telco's total sales, and for the year ended December 31, 1997, PT-1
Communications Incorporated accounted for 21% of Resurgens' total sales. If the
Telco Merger or the Resurgens Transaction is consummated, then the loss of, or a
material reduction in orders by, such key customer of Telco or Resurgens (as the
case may be) could have a material adverse effect on Holdco's business,
financial condition and results of operations.
 
     DEPENDENCE ON KEY PERSONNEL.  Each of World Access and NACT 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
Holdco's business, financial condition and results of operations. In addition,
each of World Access and NACT 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 World Access and NACT,
is currently very competitive, and World Access and NACT must compete with much
larger companies with significantly greater resources to attract and retain such
personnel. There can be no assurance that World Access and NACT will be able to
retain its existing personnel or attract other qualified employees.
 
     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%, 25.0% and 15.0% 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 Holdco's results of operations, and fluctuations in exchange
rates could affect demand for World Access' products and services.
 
     CERTAIN PENDING LITIGATION.  On August 24, 1995, 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
 
                                       19
<PAGE>   30
 
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").
The initial complaint further alleged defamation and unfair competition as a
result of a communication disseminated by NACT to its customers and tortious
interference with prospective business relations, alleging that NACT induced
third parties to abandon licensing negotiations with Aerotel. Aerotel sought
injunctive relief, damages in an unspecified amount, damages of up to three
times the 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 judgment 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 and GST USA, as well as Kyle
Love, the former President of NACT, and Dr. Thomas E. Sawyer, a director of GST
and NACT and the former Chairman and Chief Executive Officer 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. The defendants have served answers denying all
material allegations and intend to defend vigorously. On July 9, 1998, World
Access, GST and Aerotel entered into a Memorandum of Understanding with respect
to the settlement of this action, and the parties are negotiating the terms and
conditions of a final settlement agreement. World Access currently estimates
that its portion of the settlement costs, including legal fees, will be
approximately $3.3 million and will be paid through the issuance of shares of
World Access Common Stock. If a settlement does not occur, NACT's patent counsel
believes that NACT has valid defenses to the Aerotel claims (which, if upheld,
would be valid for all defendants), and the defendants intend to vigorously
defend. However, no assurances can be given as to the outcome of this action. An
unfavorable decision in this action could have a material adverse effect on
Holdco's business, financial condition and results of operations.
 
     LIMITED PROTECTION OF PROPRIETARY RIGHTS.  Each of World Access and NACT
relies on contractual rights, trade secrets, trademarks and copyrights to
establish and protect its proprietary rights in its products. Although World
Access presently holds several patents for certain of its existing products and
has several patent applications pending, NACT does not hold any patents for its
existing products and has no patent applications pending. 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 World Access nor NACT has conducted a formal patent search relating
generally to the technology used in their 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 the products of World Access
or NACT. In addition, software comprises a substantial portion of the technology
in the products of World Access and NACT. 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 World Access or
NACT if either one discovers the existence of third party patents related to its
software products or if such patents are asserted against them in the future.
Patents have been granted recently on fundamental technologies in software, and
patents may issue which relate to fundamental technologies incorporated into the
products of World Access or NACT.
 
     Intellectual property disputes may be initiated by competitors against
World Access or NACT for tactical purposes to gain competitive advantage or
overcome competitive disadvantage, even if the merits of a specific dispute are
doubtful. In the future, World Access or NACT may be required to bring or defend
against litigation to enforce any patents issued or assigned to World Access or
NACT, to protect trademarks, trade secrets and other intellectual property
rights owned by World Access or NACT, to defend World Access or NACT 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 Holdco's business, financial
condition and results of operations. Adverse determinations in litigation could
result in the loss of World Access' or NACT's proprietary rights, subject World
Access or NACT to significant liabilities, require World Access or
                                       20
<PAGE>   31
 
NACT to seek licenses from third parties or prevent World Access or NACT from
manufacturing or selling its products, any of which could have a material
adverse effect on Holdco's business, financial condition and results of
operations.
 
     Although neither World Access nor NACT expects that its proprietary rights
in its products will prevent competitors from developing products functionally
similar to World Access' or NACT's, World Access and NACT believe many aspects
of their internally developed products are proprietary and intend to monitor
closely the products introduced by competitors for any infringement of their
proprietary rights.
 
     As Holdco seeks to expand internationally, it will need to take steps to
protect its proprietary rights under foreign laws. Many of these laws are not as
well developed or do not afford the same degree of protection as United States
laws, and no assurance can be given that Holdco will not encounter difficulties
in protecting its proprietary rights outside the United States or will not
infringe the rights of others outside the United States.
 
     POSSIBLE VOLATILITY OF STOCK PRICE.  Holdco believes factors such as
announcements of new products or technological innovations by World Access, NACT
or third parties, as well as variations in Holdco's 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 Holdco 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 Holdco Common Stock.
 
     ANTI-TAKEOVER PROVISIONS.  Certain provisions of Holdco's restated
Certificate of Incorporation (the "Holdco Certificate"), Holdco's Bylaws and the
Delaware General Corporation Laws ("DGCL") could, together or separately,
discourage potential acquisition proposals or delay or prevent a change in
control of Holdco. 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 Holdco Common Stock. (In connection with the Telco Merger,
Holdco's board of directors intends to propose that the number of authorized
shares of Holdco Common Stock be increased to 150,000,000.) Holdco's 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 Holdco Common Stock will be subject to, and may be
adversely affected by, the commitments or contracts to issue any additional
shares of Holdco Common Stock (other than pursuant to outstanding stock options)
or any shares of preferred stock. Authorized and unissued preferred stock and
Holdco 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 Holdco, 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 Holdco Common Stock.
As a Delaware corporation, Holdco is subject to Section 203 of the DGCL which,
in general, prevents an "interested stockholder" (defined generally as a person
owning 15% or more of the corporation's outstanding voting stock) from engaging
in a "business combination" (as defined in Section 203) for three years
following the date such person became an interested stockholder unless certain
conditions are satisfied. See "Description of Holdco Capital 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 so-called "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.
 
                                       21

     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 October 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 will be 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 Holdco's consolidated results of operations,
liquidity and capital resources.
 
                            THE NACT SPECIAL MEETING
 
     General.  This Prospectus/Information Statement is being furnished to
stockholders of NACT in connection with the NACT Special Meeting to be held at
NACT's principal offices located at 191 West 5200 North, Provo, Utah 84604, on
October 28, 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 NACT.
 
     Matters to Be Considered.  At the NACT Special Meeting, stockholders of
record of NACT as of the close of business on the NACT Record Date will be asked
to consider and vote upon proposals (i) to approve and adopt the NACT Merger
Proposal and (ii) to transact such other business as may properly come before
the NACT Special Meeting or any adjournments or postponements thereof.
 
                                       22

     Board of Directors' Recommendations.  THE BOARD OF DIRECTORS OF NACT HAS
DETERMINED THAT THE NACT MERGER IS FAIR TO, AND IN THE BEST INTERESTS OF, THE
STOCKHOLDERS OF NACT AND HAS THEREFORE UNANIMOUSLY APPROVED AND ADOPTED THE NACT
MERGER AGREEMENT AND APPROVED THE NACT MERGER AND UNANIMOUSLY RECOMMENDS THAT
THE STOCKHOLDERS OF NACT VOTE FOR THE APPROVAL AND ADOPTION OF THE NACT MERGER
AGREEMENT AND APPROVAL OF THE NACT MERGER.
 
     NACT Record Date.  The board of directors of NACT has fixed September 22,
1998 as the record date for determination of holders of NACT Common Stock
entitled to notice of and to vote at the NACT Special Meeting. As of the close
of business on the NACT Record Date, 8,133,830 shares of NACT Common Stock were
outstanding, held by approximately 16 holders of record. Only holders of record
of NACT Common Stock as of the close of business on the NACT Record Date are
entitled to notice of and to vote at the NACT Special Meeting and any
adjournments or postponements thereof.
 
     Voting; Vote Required.  Each holder of record of NACT Common Stock on the
NACT Record Date is entitled to cast one vote for each share of NACT Common
Stock held thereby. A majority of the shares of NACT Common Stock entitled to
vote at the NACT Special Meeting will constitute a quorum for the transaction of
business at the NACT Special Meeting. The approval of the NACT Merger Agreement
and the NACT Merger will require the affirmative vote of a majority of the
outstanding shares of NACT Common Stock.
 
     Shares of NACT Common Stock that are voted "FOR," "AGAINST" or "WITHHELD"
at the NACT 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 NACT Common Stock present in person or represented by proxy at
the NACT 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 NACT Merger Proposal which approval will require the
affirmative vote of a majority of the outstanding shares of NACT Common Stock.
 
     Security Ownership by Certain Beneficial Owners and Management.  As of the
close of business on the NACT Record Date, directors and executive officers of
NACT and their respective affiliates, including World Access, may be deemed to
be the beneficial owners of shares of NACT Common Stock representing
approximately 67.2% of the outstanding voting power of NACT. See "Other
Information Regarding NACT -- Equity Ownership of Principal Stockholders and
Management." Each of the directors and executive officers of NACT has indicated
that such person intends to vote or direct the vote of all the shares of NACT
Common Stock over which such person has voting control in favor of the NACT
Merger Agreement and the NACT Merger. In addition, World Access currently owns
5,468,712 shares of NACT Common Stock, representing approximately 67.2% of the
outstanding shares of NACT Common Stock. AS A RESULT, WORLD ACCESS HAS THE RIGHT
TO VOTE SUFFICIENT SHARES TO APPROVE THE NACT MERGER AGREEMENT AND THE NACT
MERGER AT THE NACT SPECIAL MEETING WITHOUT THE AFFIRMATIVE VOTE OF ANY OTHER
NACT STOCKHOLDER, THEREBY ASSURING THE APPROVAL OF THE NACT MERGER AGREEMENT AND
THE NACT MERGER.
                             ---------------------
 
               NACT STOCKHOLDERS ARE NOT BEING ASKED FOR A PROXY
                     AND ARE REQUESTED NOT TO SEND A PROXY.
 
                             ---------------------

                              THE NACT TRANSACTION
 
PURPOSE AND EFFECTS OF THE NACT TRANSACTION
 
     The purpose of the NACT Transaction is to combine World Access and NACT. As
a result of the NACT Transaction, World Access and NACT will each become a
wholly owned subsidiary of Holdco. Holdco will derive the sole benefit of NACT's
net earnings and net book value, and former holders of NACT Common Stock will no
longer have any direct interest in NACT or be able to vote with respect to the
future affairs of NACT. Although former holders of NACT Common Stock will no
longer enjoy the possibility of a direct interest in any future appreciation in
their equity interest in NACT, after the NACT Transaction such former holders
will enjoy the future appreciation in their equity interest in Holdco, which
will include NACT.
 
     Registration of the NACT Common Stock under the Exchange Act may be
terminated upon application of NACT to the Commission if the NACT Common Stock
is neither listed on a national securities exchange nor held by more than 300
holders of record. Following consummation of the Mergers, NACT will be a wholly
owned subsidiary of Holdco, and the NACT Common Stock will be removed from
Nasdaq and will no longer trade publicly. NACT expects that the NACT Common
Stock will continue to be included in Nasdaq until the consummation of the NACT
Transaction.
 
BACKGROUND OF THE MERGERS
 
     As described above under "Summary -- World Access' Interest in NACT," in
February 1998, World Access purchased 5,113,712 shares of NACT Common Stock from
GST USA. In connection with its public announcement that it had agreed to
acquire a majority stake in NACT from GST USA, World Access announced on January
2, 1998 that it also intended to propose a merger with NACT pursuant to which
the shares of NACT Stock not owned by World Access (the "NACT Minority Shares")
would be exchanged for shares of World Access Common Stock.
 
     Following this announcement, senior management of World Access discussed
the possibility of proposing a merger to acquire the NACT Minority Shares with
the senior management of NACT. On January 12, 1998, the board of directors of
NACT established a special committee (the "Special Committee") comprised of
Ronald S. Eliason and Thomas E. Sawyer, neither of whom is an employee of NACT
or has any direct or indirect interest in World Access, to review and consider
the desirability, from the perspective of the holders of the NACT Minority
Shares, of a merger between NACT and World Access. The Special Committee was
authorized to retain, at NACT's expense, such advisors and consultants as it
deemed appropriate.
 
     On January 9, 1998, the Special Committee retained the law firm of Van
Cott, Bagley, Cornwall & McCarthy to advise the Special Committee. On January
13, 1998, the Special Committee retained NationsBanc Montgomery to provide the
Special Committee with financial advisory services with respect to any merger
proposal from World Access and to provide a written opinion as to the fairness,
from a financial point of view, of the consideration to be received by the
holders of NACT Minority Shares in connection therewith. On August 1, 1998, the
attorney representing the Special Committee terminated his affiliation with Van
Cott, Bagley, Cornwall & McCarthy and became affiliated with the firm of Parsons
Behle & Latimer.
 
     On January 15, 1998, World Access proposed to the Special Committee a
business combination with NACT in which the NACT Minority Shares would be
exchanged for World Access Common Stock having a value of $17.50 per share,
subject to the negotiation of a mutually-satisfactory collar. In addition, the
initial proposal by World Access provided that the business combination would be
subject to (i) the Special Committee's recommendation to the NACT board of
directors to proceed with the transaction; (ii) the approval of the transaction
by the NACT board of directors; (iii) execution of a definitive agreement in
form and substance satisfactory to NACT and World Access; (iv) approval of the
transaction by the holders of a majority of the outstanding shares of NACT
common stock; and (v) consummation of the Stock Purchase Transaction.
 
     On February 5, 1998, counsel to World Access distributed to the Special
Committee and its counsel a draft of the NACT Merger Agreement. Between February
5, 1998 and February 18, 1998, senior management
 
                                       24
<PAGE>   35
 
of World Access and its counsel and the Special Committee and its counsel
negotiated the terms of the NACT Merger Agreement and the proposed NACT Merger.
During this period, World Access proposed a 10% "collar" on the proposed
exchange ratio, and on February 12, 1998, counsel to World Access circulated to
the Special Committee and its counsel a letter describing the proposed
adjustments to the exchange ratio based upon fluctuations in the trading price
of the World Access Common Stock if the parties adopted the 10% collar proposed
by World Access.
 
     The Special Committee reviewed the proposed collar with its counsel and
NationsBanc Montgomery and further sought to negotiate and clarify the
adjustments to the exchange ratio as a result of the increase or decrease in the
trading price of the World Access Common Stock.
 
     On February 18, 1998, senior management of World Access and its counsel met
with the Special Committee and its counsel in Provo, Utah to further negotiate
and discuss the terms of the NACT Merger Agreement and proposed NACT Merger. At
that meeting, World Access tentatively agreed to fix the price of the World
Access Common Stock from which the 10% collar would be determined (the "Base
Price") by discounting the closing price of the World Access Common Stock on
February 18, 1998 by approximately 7%, to approximately $26.00 per share.
 
     On February 24, 1998, the Special Committee proposed that the Base Price be
lowered to $22.20 per share, the closing price of the World Access Common Stock
on February 24, 1998 less the same 7% discount discussed at the February 18
meeting (the "First Adjusted Base Price") due to the significant decline in the
trading price of the World Access Common Stock. World Access promptly advised
the Special Committee that the First Adjusted Base Price was unacceptable and
proposed that the Base Price be set at $24.00 per share (the "Second Adjusted
Base Price").
 
     On February 24, 1998, the Special Committee advised World Access that the
Second Adjusted Base Price was unacceptable and proposed to set the Base Price
at $23.20 (the "Final Base Price"), which would ensure that the NACT Minority
Shares would be exchanged for shares of Holdco Common Stock with a value per
share no less favorable than the value per share received by GST USA in
connection with the NACT Stock Purchase and that holders of the NACT Minority
Shares would receive shares of Holdco Common Stock having a value of greater
than $17.50 per share if the World Access Average Closing Price were to exceed
$25.51 per share.
 
     On February 24, 1998, the World Access board of directors agreed to the
Final Base Price and unanimously approved the NACT Merger Agreement and the
Mergers and authorized management of World Access to negotiate, execute and
deliver the NACT Merger Agreement. Immediately thereafter, NationsBanc
Montgomery delivered its fairness opinion to the Special Committee, the NACT
board of directors unanimously approved the NACT Merger Agreement and the NACT
Merger and the NACT Merger Agreement was executed.
 
     In June 1998, the boards of directors of World Access, Holdco and NACT
unanimously approved the proposed amendment to the Merger Agreement, which
amendment had been recommended by counsel to World Access to clarify certain
provisions of the Merger Agreement.
 
WORLD ACCESS' REASONS FOR THE NACT MERGER; RECOMMENDATION OF WORLD ACCESS' BOARD
OF DIRECTORS
 
     The board of directors of World Access has carefully considered the
advisability of the NACT Merger and believes that the terms of the NACT Merger
are fair to, and that the NACT Merger is in the best interests of, the
stockholders of World Access. THE BOARD OF DIRECTORS OF WORLD ACCESS HAS
UNANIMOUSLY APPROVED AND ADOPTED THE NACT MERGER AGREEMENT AND APPROVED THE NACT
MERGER.
 
     In approving the NACT Merger Agreement and the NACT Merger, the board of
directors of World Access consulted with World Access management, as well as its
legal advisors, and also considered, among other things: (i) the business,
managerial expertise, business strategy, prospects and competitive position of
NACT and World Access; (ii) historical, current and projected financial
condition and results of operations of NACT (without giving effect to the NACT
Merger) and of Holdco (after giving effect to the Mergers); (iii) the
consideration to be paid to NACT stockholders and other terms of the NACT Merger
Agreement;
                                       25
<PAGE>   36
 
(iv) after consummation of the NACT Merger, World Access will have significantly
increased flexibility to add expertise and resources to NACT and to use the
expertise and resources of NACT in World Access' other related operations; (v)
the NACT Merger will enable World Access to operate NACT without any possible
conflicts of interest created by the existence of a minority interest in NACT;
and (vi) the elimination of the cost of public ownership of NACT, including the
preparation and mailing of annual reports to NACT stockholders, the preparation
of periodic reports under the Exchange Act, solicitation of proxies for annual
meetings of stockholders, transfer agent fees, and other stockholder services
directly related to public ownership.
 
NACT'S REASONS FOR THE NACT MERGER; RECOMMENDATION OF NACT'S BOARD OF DIRECTORS
 
     After receiving the recommendation of the Special Committee, the board of
directors of NACT carefully considered the advisability of the NACT Merger and
has concluded and believes that the terms of the NACT Merger Agreement are fair
to, and that the NACT Merger is in the best interests of, NACT and its
stockholders (other than World Access). THE BOARD OF DIRECTORS OF NACT HAS
UNANIMOUSLY APPROVED AND ADOPTED THE NACT MERGER AGREEMENT AND APPROVED THE NACT
MERGER AND UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS OF NACT VOTE FOR THE
APPROVAL AND ADOPTION OF THE NACT MERGER AGREEMENT AND APPROVAL OF THE NACT
MERGER.
 
     In approving the NACT Merger Agreement and the NACT Merger, and in
recommending that NACT's stockholders approve the NACT Merger, the NACT board of
directors consulted with NACT management, as well as its financial and legal
advisors, and also considered, among other things: (i) the business, managerial
expertise, business strategy, prospects and competitive position of NACT and
World Access; (ii) historical, current and projected financial condition and
results of operations of NACT (without giving effect to the NACT Merger) and of
Holdco (after giving effect to the Mergers); (iii) the consideration to be paid
to NACT stockholders and other terms of the NACT Merger Agreement; (iv) the
financial presentation and opinion of NACT's financial advisor, described below
under "-- Opinion of NACT's Financial Advisor"; (v) the recommendation of the
Special Committee; (vi) the historical market prices and recent trading activity
of the NACT Common Stock and the fact that the NACT Merger will enable NACT's
stockholders to realize a significant premium over the prices at which the NACT
Common Stock may trade in a market unaffected by merger speculation; (vii) the
expectation that the market capitalization and public stock distribution of
Holdco will provide NACT's stockholders with increased liquidity; (viii) the
fact that NACT's stockholders will obtain tax-free treatment in connection with
the NACT Merger and will continue as stockholders of a larger, more diversified
combined company having greater market and financial strength; (ix) the fact
that the NACT Merger Agreement provides a "collar" limiting the effect of
changes in the price of World Access Common Stock on the value of the
consideration to be received by NACT's stockholder in the NACT Merger; and (x)
NACT's limited ability to engage in other transactions with respect to the NACT
Minority Shares in light of World Access' majority ownership of NACT.
 
     The board of directors of NACT also considered a variety of inherent risks
and potentially negative factors in its deliberations concerning the NACT
Merger. In particular, the board of directors of NACT considered, among other
things, the following: (i) the irreversible nature of the decision and the
consequent loss of even its limited independence; (ii) the possible change in
certain existing NACT corporate policies and strategies following the NACT
Merger; (iii) the potential for post-merger dilution of Holdco's earnings per
share; and (iv) the other risks described above under "Risk Factors." In the
view of the board of directors of NACT, these considerations did not outweigh,
individually or collectively, the advantages of the NACT Merger to NACT. The
board of directors of NACT also took into account the fact that the NACT Merger
is not conditioned on the approval by the holders of at least a majority of the
NACT Minority Shares.
 
     Due to the wide variety of factors considered in connection with the
evaluation of the NACT Merger, NACT's board of directors did not find it
practicable to evaluate, and did not quantify or otherwise attempt to assign
relative weights to, the specific factors considered in reaching its
determination. In addition, individual members of NACT's board of directors may
have given different weight to different factors.

     The NACT board of directors does not believe (i) that it is necessary to
obtain an updated fairness opinion to take into account the Resurgens
Transaction or the Telco Merger because the consideration to be received by the
NACT stockholders in connection with the NACT Merger is fixed at $17.50 per
share (subject to the collar) or (ii) that the Resurgens Transaction and the
Telco Merger affect the value of such fixed merger consideration. Moreover, NACT
has no right to terminate the Merger Agreement based on its obtaining or not
obtaining an updated fairness opinion. Accordingly, the NACT board of directors
does not believe that, under the circumstances, requesting an updated fairness
opinion would serve any useful purpose. In addition, the Special Committee was
not charged with the responsibility of monitoring the bases for its
recommendation to the NACT board of directors in the event of significant delays
in consummating the NACT Transaction.
 
     NACT Board Recommendation.  NACT's board of directors has approved the NACT
Merger Agreement and the NACT Merger and determined that the NACT Merger is fair
to, and in the best interests of, NACT and its stockholders (other than World
Access). After careful consideration, the board of directors of NACT unanimously
recommends that the stockholders of NACT vote in favor of the NACT Merger
Agreement and the NACT Merger.
 
OPINION OF NACT'S FINANCIAL ADVISOR
 
     NACT engaged NationsBanc Montgomery to render a fairness opinion to the
Special Committee in connection with the NACT Merger pursuant to an engagement
letter dated January 13, 1998. NationsBanc Montgomery is a nationally recognized
investment banking firm and, as part of its investment banking activities, is
regularly engaged in the valuation of businesses and their securities in
connection with merger transactions and other types of acquisitions, negotiated
underwritings, secondary distributions of listed and unlisted securities,
private placements and valuations for corporate and other purposes. NACT
selected NationsBanc Montgomery to render a fairness opinion on the basis of its
experience and expertise in transactions similar to the NACT Merger, its
reputation in the communications industry and its historical investment banking
relationship with NACT. The fairness opinion of NationsBanc Montgomery will not
be updated to take into consideration the Resurgens Transaction or the Telco
Merger.
 
     At the February 24, 1998 meeting of the Special Committee, NationsBanc
Montgomery delivered its oral opinion, subsequently confirmed in writing as of
the same date, that the consideration to be received by the stockholders of NACT
in the NACT Merger was fair to such stockholders from a financial point of view,
as of the date of such opinion. NationsBanc Montgomery did not determine the
form or amount of consideration to be received by NACT's stockholders in the
NACT Merger. The amount of such consideration was agreed to as a result of
negotiations between NACT and World Access. No limitations were imposed by NACT
on NationsBanc Montgomery with respect to the investigations made or procedures
followed in rendering its opinion. NationsBanc Montgomery was not requested to,
nor did it, advise the Special Committee with respect to alternatives to the
NACT Merger or NACT's underlying decision to proceed with or effect the NACT
Merger.
 
     THE FULL TEXT OF NATIONSBANC MONTGOMERY'S WRITTEN OPINION TO THE SPECIAL
COMMITTEE, WHICH SETS FORTH THE ASSUMPTIONS MADE, MATTERS CONSIDERED AND
LIMITATIONS OF REVIEW BY NATIONSBANC MONTGOMERY, IS ATTACHED HERETO AS APPENDIX
B AND IS INCORPORATED HEREIN BY REFERENCE AND SHOULD BE READ CAREFULLY AND IN
ITS ENTIRETY. THE FOLLOWING SUMMARY OF NATIONSBANC MONTGOMERY'S OPINION IS
QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF THE OPINION.
NATIONSBANC MONTGOMERY'S OPINION IS ADDRESSED TO THE SPECIAL COMMITTEE ONLY AND
DOES NOT CONSTITUTE A RECOMMENDATION TO ANY NACT STOCKHOLDER AS TO HOW SUCH
STOCKHOLDER SHOULD VOTE AT THE SPECIAL MEETING. IN FURNISHING ITS OPINION,
NATIONSBANC MONTGOMERY DID NOT ADMIT THAT IT IS AN EXPERT WITHIN THE MEANING OF
THE TERM "EXPERT", AS USED IN THE SECURITIES ACT AND THE RULES AND REGULATIONS
PROMULGATED THEREUNDER, OR THAT ITS OPINION IS A REPORT OR VALUATION WITHIN THE
MEANING OF SECTION 11 OF THE SECURITIES ACT, AND STATEMENTS TO SUCH EFFECT ARE
INCLUDED IN NATIONSBANC MONTGOMERY'S OPINION.
 
     In connection with its opinion, NationsBanc Montgomery, among other things:
(i) reviewed certain publicly available financial and other data with respect to
NACT and World Access, including the
 
                                       27
<PAGE>   38
 
consolidated financial statements for recent years and interim periods to
December 31, 1997 with respect to NACT and September 30, 1997 with respect to
World Access and certain other relevant financial and operating data relating to
NACT made available to NationsBanc Montgomery from published sources and from
the internal records of NACT; (ii) reviewed the financial terms and conditions
of the draft NACT Merger Agreement; (iii) reviewed certain publicly available
information concerning the trading of, and the trading market for, NACT Stock
and World Access Stock; (iv) compared NACT from a financial point of view with
certain other companies in the voice switching and other enhanced voice
applications industries which NationsBanc Montgomery deemed to be relevant; (v)
compared World Access from a financial point of view with certain other
companies in the transmission and switching, wireline access and wireless access
industries; (vi) considered the financial terms, to the extent publicly
available, of selected recent business combinations of companies in the voice
switching and other enhanced voice applications industries which NationsBanc
Montgomery deemed to be comparable, in whole or in part, to the NACT Merger;
(vii) considered the premiums paid in comparable public market acquisitions of
selected businesses within the technology industries; (viii) considered the
premiums paid in transactions involving acquisitions of the remaining
publicly-held minority interests by the majority interest holder; (ix) reviewed
and discussed with representatives of the management of NACT and World Access
certain information of a business and financial nature regarding NACT and World
Access furnished to NationsBanc Montgomery by them, including financial
forecasts and related assumptions of NACT; (x) made inquiries regarding and
discussed the NACT Merger and the draft NACT Merger Agreement and other matters
related thereto with NACT's counsel; and (xi) performed such other analyses and
examinations as NationsBanc Montgomery deemed appropriate.
 
     In connection with its review, NationsBanc Montgomery did not assume any
obligation independently to verify the foregoing information and relied on such
information being accurate and complete in all material respects. With respect
to the financial forecasts for NACT provided to NationsBanc Montgomery by NACT's
management, upon its advice and with its consent, NationsBanc Montgomery assumed
for purposes of its opinion that the forecasts, including the assumptions
regarding synergies, were reasonably prepared on bases reflecting the best
available estimates and judgments of NACT's management at the time of
preparation as to the future financial performance of NACT and that they
provided a reasonable basis upon which NationsBanc Montgomery could form its
opinion. NationsBanc Montgomery also assumed that there were no material changes
in NACT's or World Access' assets, financial condition, results of operations,
business or prospects since the respective dates of their last financial
statements made available to NationsBanc Montgomery. NationsBanc Montgomery
assumed that the NACT Merger would be consummated in a manner that complies in
all respects with the applicable provisions of the Securities Act, the Exchange
Act and all other applicable federal and state statutes, rules and regulations.
In addition, NationsBanc Montgomery did not assume responsibility for making an
independent evaluation, appraisal or physical inspection of any of the assets or
liabilities (contingent or otherwise) of NACT or World Access, nor was
NationsBanc Montgomery furnished with any such appraisals. NACT informed
NationsBanc Montgomery, and NationsBanc Montgomery assumed, that the NACT Merger
would be recorded as a purchase under generally accepted accounting principles.
Finally, NationsBanc Montgomery's opinion was based on economic, monetary and
market and other conditions as in effect on, and the information made available
to it as of, February 24, 1998. Accordingly, although subsequent developments
may affect NationsBanc Montgomery's opinion, NationsBanc Montgomery has not
assumed any obligation to update, revise or reaffirm its opinion.
 
     The following is a summary of the material analyses and factors considered
by NationsBanc Montgomery in connection with its opinion to the Special
Committee dated February 24, 1998.
 
     Comparable Company Analysis.  NationsBanc Montgomery compared the value of
the consideration to be received by the stockholders of NACT in the NACT Merger
to certain financial and stock market information of publicly-traded companies
engaged in the voice switching and other enhanced voice applications industries
that NationsBanc Montgomery believed were comparable in certain respects to NACT
(the "Comparable Companies"). The Comparable Companies are comprised of ACE*COMM
Corporation, Aspect Telecommunications Corporation, Bright Voice Systems, Inc.,
Excel Switching Corporation, Premiere Technologies, Inc., Summa Four, Inc.,
Syntellect, Inc. and Tekelec and were chosen by NationsBanc
 
                                       28

Montgomery as companies that, based on publicly available data, possess general
business, operating and financial characteristics representative of companies in
the industry in which NACT operates, although NationsBanc Montgomery recognizes
that each of the Comparable Companies is distinguishable from NACT in certain
respects.
 
     For each of the Comparable Companies and NACT, NationsBanc Montgomery
obtained certain publicly available financial, operating and stock market data,
including last twelve months ("LTM") revenue, projected calendar year 1998
revenue, projected calendar year 1998 earnings per share ("EPS"), recently
reported total debt and cash and cash equivalents, and closing stock price as of
February 20, 1998. Calendar year 1998 EPS estimates for the Comparable Companies
and NACT were based on analysts' estimates as reported by First Call, a market
research database.
 
     NationsBanc Montgomery also compiled the "aggregate value" for each of the
Comparable Companies and for NACT implied in the NACT Merger. Aggregate value is
the total current equity value plus total debt less cash and cash equivalents.
 
     Based on this data, NationsBanc Montgomery calculated the following ratios
for each of the Comparable Companies and for NACT implied in the NACT Merger:
aggregate value to LTM revenue; aggregate value to calendar year 1998 revenue;
and current stock price to projected 1998 earnings per share ("1998
price/earnings ratio").
 
     The aggregate value to the LTM revenues for the Comparable Companies ranged
from 0.5x to 9.2x, compared to 4.4x for NACT implied in the NACT Merger. The
selected aggregate value to calendar year 1998 revenue for the Comparable
Companies ranged from 0.5x to 6.1x, compared to 3.2x for NACT implied in the
NACT Merger. The selected 1998 price/earnings ratio for the Comparable Companies
ranged from 21.2x to 44.0x, compared to 21.6x for NACT implied in the NACT
Merger.
 
     Comparable Mergers and Acquisitions Analysis.  NationsBanc Montgomery
reviewed certain financial data for 33 recently announced mergers and
acquisitions in the voice switching and other enhanced voice applications
industries that were deemed to be comparable to the NACT Merger (the "Comparable
Acquisitions"), the most comparable of which were Lucent Technologies, Inc.'s
acquisition of Octel Communications, Inc. and Comverse Technology, Inc.'s
acquisition of Boston Technology, Inc.
 
     For each such transaction NationsBanc Montgomery calculated the ratio of
aggregate value to LTM revenues, the ratio of aggregate value to LTM earnings
before interest and taxes ("EBIT") and the ratio of equity value to LTM net
income. All multiples were based on publicly available information at the time
of announcement of the Comparable Acquisitions. The transactions yielded a
selected range of aggregate value to LTM revenue of 0.3x to 16.0x, compared to
4.4x for NACT implied in the NACT Merger. The transaction yielded a selected
range of aggregate values to LTM EBIT of 6.4x to 41.5x, compared to 20.5x for
NACT implied in the NACT Merger.
 
     Premiums Paid in Technology Transactions Analysis.  NationsBanc Montgomery
reviewed the premiums paid in selected transactions that were deemed to be
comparable to the NACT Merger involving technology companies in the past three
years.
 
     In each of these transactions, NationsBanc Montgomery calculated the
premiums of the price paid by acquirors over the target company's stock price 30
days prior to public announcement of the transaction. These calculations yielded
a reasonable range of premiums paid based on the target company's stock price
four weeks prior to public announcement of the transaction of 0.0% to 60.0%.
NationsBanc Montgomery then calculated the premium to be paid in the NACT Merger
based on the value of $17.50 per NACT share to both NACT's stock price four
weeks prior to the public announcement of the NACT Stock Purchase Agreement and
NACT's stock price four weeks prior to the public announcement of the NACT
Merger. These calculations yielded premiums paid of 17.6% and 45.8%,
respectively.
 
     Premiums Paid in the Acquisition of Minority Interests Analysis.
NationsBanc Montgomery reviewed the premiums paid in selected transactions that
were deemed to be comparable to the NACT Merger involving the acquisition of the
remaining minority interest by the majority shareholder in the past six years.

a reasonable range of premiums paid based on the target company's stock price
four weeks prior to public announcement of the transaction of 0.0% to 40.0%.

weeks prior to the public announcement of the NACT Stock Purchase Agreement and
NACT's stock price four weeks prior to the public announcement of the NACT
Merger. These calculations yielded premiums paid of 17.6% and 45.8%,
respectively.
 
     Accretion/Dilution Analysis.  NationsBanc Montgomery analyzed the impact of
the NACT Merger on World Access stockholders on a pro forma fully diluted EPS
basis for calendar years 1998. NationsBanc Montgomery used World Access internal
estimates for calendar year 1998 for NACT and World Access internal estimates
for calendar year 1998 for World Access and performed the analysis giving effect
to $3.96 million of synergies anticipated by the managements of World Access and
NACT to result from the NACT Merger for the ten months of combined results for
calendar year 1998. The analysis indicated that, for World Access stockholders,
the NACT Merger would be breakeven in calendar year 1998 with the realization of
the synergies. The actual results achieved by the combined company may vary from
projected results and the variations may be material.
 
     Discounted Cash Flow Analysis.  NationsBanc Montgomery performed a
discounted cash flow analysis on certain projected financial statements that
were provided to NationsBanc Montgomery by the management of NACT.
 
     In performing this analysis, NationsBanc Montgomery calculated the
projected stand-alone unlevered after-tax cash flows for the fiscal years 1998
through 2002. NationsBanc Montgomery calculated NACT's terminal values in fiscal
year 2002 based on price/next twelve month earnings multiples ranging from 18.0x
to 22.0x. The unlevered after-tax cash flows and the terminal value were
discounted to the present using discount rates ranging from 22.5% to 27.5%. This
analysis yielded an equity value range for NACT of $15.04 to $21.64 per share.
 
     Contribution Analysis.  NationsBanc Montgomery performed a contribution
analysis for the calendar year 1998. NationsBanc Montgomery used NationsBanc
Montgomery estimates for calendar year 1998 for NACT and Prudential Securities
estimates for calendar year 1998 for World Access. Accordingly, NACT contributed
22.1% of the combined revenues, 21.6% of the combined operating income, and
20.6% of the combined net income, as compared to its 21.6% ownership of the
combined entity.
 
     The summary set forth above does not purport to be a complete description
of the presentation by NationsBanc Montgomery to the Special Committee or the
analyses performed by NationsBanc Montgomery. The preparation of a fairness
opinion is not necessarily susceptible to partial analysis or summary
description. NationsBanc Montgomery believes that its analyses and the summary
set forth above must be considered as a whole and that selecting portions of its
analyses and of the factors considered, without considering all analyses and
factors, would create an incomplete view of the process underlying the analyses
set forth in its presentation to the Special Committee. In addition, NationsBanc
Montgomery may have given various analyses more or less weight than other
analyses, and may have deemed various assumptions more or less probable than
other assumptions so that the ranges of valuations resulting from any particular
analysis described above should not be taken to be NationsBanc Montgomery's view
of the actual value of NACT. The fact that any specific analysis has been
referred to in the summary above is not meant to indicate that such analysis was
given greater weight than any other analysis. In arriving at its opinion,
NationsBanc Montgomery did not ascribe a specific range of values to NACT, but
rather made its determination as to the fairness, from a financial point of
view, of the consideration to be received by the holders of NACT Common Stock in
the NACT Merger on the basis of the financial and comparative analyses described
above.
 
     In performing its analyses, NationsBanc Montgomery made numerous
assumptions with respect to industry performance, general business and economic
conditions and other matters, many of which are beyond the control of NACT. The
analyses performed by NationsBanc Montgomery are not necessarily indicative of
actual values or actual future results, which may be significantly more or less
favorable than suggested by such
                                       30
<PAGE>   41
 
analyses. Such analyses were prepared solely as part of NationsBanc Montgomery's
analysis of the fairness of the transaction contemplated by the NACT Merger
Agreement to NACT's stockholders from a financial point of view and were
provided to the Special Committee in connection with the delivery of NationsBanc
Montgomery's opinion. The analyses do not purport to be appraisals or to reflect
the prices at which a company might actually be sold or the prices at which any
securities may trade at the present time or at any time in the future.
NationsBanc Montgomery used in its analyses various projections of future
performance prepared by the management of NACT. The projections are based on
numerous variables and assumptions which are inherently unpredictable and must
be considered not certain of occurrence as projected. Accordingly, actual
results could vary significantly from those set forth in such projections.
 
     Pursuant to the terms of NationsBanc Montgomery's engagement, NACT has
agreed to pay NationsBanc Montgomery a fee in cash equal to $250,000, all of
which became payable upon delivery of its opinion. In addition to the foregoing
fees, NACT has agreed to reimburse NationsBanc Montgomery for all reasonable
out-of-pocket costs and expenses (including counsel fees). Pursuant to a
separate letter agreement, NACT had agreed to indemnify NationsBanc Montgomery,
its affiliates, and their respective partners, directors, officers, agents,
consultants, employees and controlling persons against certain liabilities,
including liabilities under federal securities laws.
 
     In the ordinary course of business, NationsBanc Montgomery actively trades
NACT Common Stock for its own account and for the accounts of customers and,
accordingly, may at any time hold a long or short position in such securities.
NationsBanc Montgomery has also acted as an underwriter in connection with the
public offering of NACT Common Stock.
 
FEDERAL INCOME TAX CONSEQUENCES
 
  World Access Merger
 
     The discussion set forth below (including the discussion under
"-- Treatment of Holdco, World Access and WAXS Merger Sub" and "-- Conversion of
World Access Common Stock into Holdco Common Stock") is the opinion of Rogers &
Hardin LLP as to the material Federal income tax consequences of the World
Access Merger. Such opinion is not binding on the IRS. The opinion is based upon
the provisions of the Code, applicable Treasury Regulations thereunder, judicial
decisions and current administrative rulings, any of which may be changed at any
time with retroactive effect. The opinion does not address all aspects of
Federal income taxation that may be important to particular taxpayers in light
of their personal investment circumstances or to taxpayers subject to special
treatment under the Federal income tax laws (including life insurance companies,
foreign persons, tax-exempt entities, holders who acquired their World Access
Common Stock pursuant to the exercise of employee stock options or otherwise as
compensation and persons who hold, directly or indirectly, 10% or more of World
Access Common Stock or any class of World Access Common Stock) and does not
address any aspect of state, local or foreign taxation. The opinion also assumes
that World Access Common Stock will be held as a capital asset at the time of
the consummation of the World Access Merger. No rulings have been or will be
requested from the IRS with respect to any of the matters discussed herein.
There can be no assurance that future legislation, regulations, administrative
rulings or court decisions would not alter the tax consequences set forth below.
 
     Based upon representation letters, which will be reconfirmed prior to the
consummation of the Mergers, it is the opinion of Rogers & Hardin LLP that the
World Access Merger will be treated as a transfer of property to Holdco by the
holders of World Access Common Stock and governed by Section 351 of the Code.
The opinion is based on current law and assumes that the Mergers will be
consummated as described in this Prospectus/Information Statement and in
accordance with the NACT Merger Agreement and related agreements in their
current form. It is a condition to the obligation of World Access to consummate
the World Access Merger that it shall have received confirmation, dated the
Closing Date (as hereinafter defined), of the opinion contained in this
paragraph.
 
     Treatment of Holdco, World Access and WAXS Merger Sub.  No gain or loss
will be recognized by Holdco, World Access or WAXS Merger Sub as a result of the
World Access Merger.
 
                                       31
<PAGE>   42
 
     Conversion of World Access Common Stock into Holdco Common Stock.  A holder
of World Access Common Stock whose shares of World Access Common Stock are
converted in the World Access Merger into shares of Holdco Common Stock will not
recognize gain or loss upon such conversion. The tax basis of the Holdco Common
Stock received by such holder will be equal to the tax basis of the World Access
Common Stock so converted, and the holding period of the Holdco Common Stock
will include the holding period of the World Access Common Stock so converted.
 
     Reporting Requirements.  Each holder of World Access Common Stock who
receives Holdco Common Stock in the World Access Merger will be required to
retain records and file with such holder's Federal income tax return a statement
setting forth certain facts relating to the World Access Merger.
 
  NACT Merger
 
     The discussion set forth below (including the discussion under
"-- Treatment of Holdco, NACT and NACT Merger Sub," "-- Conversion of NACT
Common Stock" and "-- Cash in Lieu of Fractional Shares") is the opinion of Van
Cott, Bagley, Cornwall & McCarthy as to the material Federal income tax
consequences of the NACT Merger. Such opinion is not binding on the IRS. The
opinion is based upon the provisions of the Code, applicable Treasury
Regulations thereunder, judicial decisions and current administrative rulings,
any of which may be changed at any time with retroactive effect. The opinion
does not address all aspects of Federal income taxation that may be important to
particular taxpayers in light of their personal investment circumstances or to
taxpayers subject to special treatment under the Federal income tax laws
(including life insurance companies, foreign persons, tax-exempt entities,
holders who acquired their NACT Common Stock pursuant to the exercise of
employee stock options or otherwise as compensation and persons who hold,
directly or indirectly, 10% or more of NACT Common Stock) and does not address
any aspect of state, local or foreign taxation. The opinion also assumes that
NACT Common Stock will be held as a capital asset at the time of the
consummation of the NACT Merger. No rulings have been or will be requested from
the IRS with respect to any of the matters discussed herein. There can be no
assurance that future legislation, regulations, administrative rulings or court
decisions would not alter the tax consequences set forth below.
 
     Based upon representation letters, which will be reconfirmed prior to the
consummation of the Mergers, it is the opinion of Van Cott, Bagley, Cornwall &
McCarthy that the NACT Merger will be treated as a transfer of property to
Holdco by the holders of NACT Common Stock governed by Section 351 of the Code.
The opinion is based on current law and assumes that the Mergers will be
consummated as described in this Prospectus/Information Statement and in
accordance with the NACT Merger Agreement and related agreements in their
current form. It is a condition to the obligation of NACT to consummate the NACT
Merger that it shall have received confirmation, dated the Closing Date, of the
opinion contained in this paragraph.
 
     Treatment of Holdco, NACT and NACT Merger Sub.  No gain or loss will be
recognized by Holdco, NACT or NACT Merger Sub as a result of the NACT Merger.
 
     Conversion of NACT Common Stock into Holdco Common Stock.  A holder of NACT
Common Stock whose shares of NACT Common Stock are converted in the NACT Merger
into the right to receive shares of Holdco Common Stock will not recognize gain
or loss upon such conversion, except to the extent cash is received in lieu of
fractional shares. See "-- Cash in Lieu of Fractional Shares" below. The
aggregate tax basis of the Holdco Common Stock received by such holder will be
equal to the aggregate tax basis of the NACT Common Stock so converted
(excluding any portion of the holder's basis allocated to fractional shares),
and the holding period of the Holdco Common Stock will include the holding
period of the NACT Common Stock so converted.
 
     Cash in Lieu of Fractional Shares.  A holder of NACT Common Stock who
receives cash in lieu of fractional shares of Holdco Common Stock will be
treated as having received such fractional shares pursuant to the NACT Merger
and then as having exchanged such fractional shares for cash in a redemption by
Holdco. Any gain or loss attributable to fractional shares will generally be
capital gain or loss. The amount of such gain or loss will be equal to the
difference between the ratable portion of the tax basis of the NACT Common Stock
converted in the NACT Merger that is allocated to such fractional shares and the
cash
                                       32
<PAGE>   43
 
received in lieu thereof. Any such capital gain or loss will constitute
long-term capital gain or loss if such NACT Common Stock has been held by the
holder for more than one year at the time of the consummation of the NACT
Merger.
 
     Reporting Requirements.  Each holder of NACT Common Stock who receives
Holdco Common Stock in the NACT Merger will be required to retain records and
file with such holder's Federal income tax return a statement setting forth
certain facts relating to the NACT Merger.
 
LIMITATIONS ON RESALES BY AFFILIATES
 
     All shares of Holdco Common Stock received by NACT stockholders in the NACT
Merger will be freely transferable, except that shares of Holdco Common Stock
received by persons who are deemed to be "affiliates" of NACT prior to the NACT
Merger may be resold by them only in transactions permitted by the resale
provisions of Rule 145 promulgated under the Securities Act (or Rule 144 in the
case of such persons who become affiliates of Holdco) or otherwise in compliance
with (or pursuant to an exemption from) the registration requirements of the
Securities Act. Persons deemed to be "affiliates" of NACT 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

registration requirements of the Securities Act.
 
EFFECT OF NACT TRANSACTION ON CERTAIN OUTSTANDING WORLD ACCESS CONVERTIBLE
SECURITIES
 
     As of August 28, 1998, there was $115,000,000 aggregate principal amount at
maturity of the World Access Notes outstanding. The World Access Notes were
issued under an Indenture dated as of October 1, 1997 (the "World Access
Indenture") between World Access and First Union National Bank, as trustee. The
World Access Notes are convertible into shares of World Access Common Stock at a
conversion price of $37.03125 per share, subject to adjustment for certain
events. Upon consummation of the Mergers, Holdco will enter into a supplemental
indenture to the World Access Indenture pursuant to which Holdco will
irrevocably and unconditionally guarantee World Access' obligations with respect
to the World Access Notes and which will provide that thereafter, subject to the
terms and conditions set forth in the World Access Indenture, the World Access
Notes will be convertible into the number of shares of Holdco Common Stock which
a holder of World Access Notes would have received if such holder had converted
such World Access Notes immediately prior to the Mergers, subject to the
adjustment thereafter upon the happening of the same events that currently
result in an adjustment to the World Access Notes pursuant to the World Access
Indenture
 
ACCOUNTING TREATMENT
 
     The NACT Transaction will be accounted for by Holdco under the purchase
method of accounting for business combinations. See "Unaudited Pro Forma
Condensed Consolidated Financial Statements."
 
INTERESTS OF CERTAIN PERSONS IN THE NACT MERGER
 
     In considering the recommendation of the NACT board of directors with
respect to the NACT Merger Agreement and the NACT Merger, holders of NACT Common
Stock should be aware that certain members of NACT's management and its board of
directors have interests in the NACT Merger that are in addition to the
interests of NACT's stockholders in general.
 
     NACT Option Grants.  In connection with entering into the NACT Stock
Purchase Agreement, on December 31, 1997, World Access entered into option
exchange agreements (the "Option Exchange Agreements") with the holders of
options to purchase an aggregate of 934,900 shares of NACT Common Stock (the
"Exchanged Options"), representing approximately 99.4% 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 World Access and now constitutes an option
                                       33
<PAGE>   44
 
to acquire, on the same terms and conditions as were applicable under such
Exchanged Option, a number of shares of World Access Common Stock equal to the
product of (i) the number of shares of NACT Common Stock subject to such
Exchanged Option and (ii) 0.8390 at an exercise price per share equal to (A) the
aggregate exercise price for such shares of NACT Common Stock subject to such
Exchanged Option, divided by (B) the number of full shares of World Access
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 or subject to any vesting requirements. As a result of
the NACT Transaction, the Exchange Options will become exercisable for shares of
Holdco Common Stock on a one-for-one basis.
 
     Indemnification; Indemnification Agreements.  Pursuant to the NACT Merger
Agreement, Holdco and World Access have agreed that all rights to
indemnification for acts or omissions occurring prior to the Effective Time of
the Mergers (as hereinafter defined) existing in favor of the current or former
directors or officers of NACT as provided in the NACT Certificate of
Incorporation and the NACT By-Laws shall survive the NACT Merger and shall
continue in full force and effect in accordance with their terms. Holdco has
agreed to cause to be maintained for a period of not less than six years from
the Effective Time of the Mergers NACT's directors' and officers' insurance and
indemnification policy in effect as of February 24, 1998, to the extent that it
provides coverage for events occurring prior to the Effective Time of the
Mergers, so long as the annual premium therefor would not be in excess of 125%
of the last annual premium paid prior to February 24, 1998 (the "Maximum
Premium"). If such policy expires, is terminated or canceled during such
six-year period, Holdco will use all reasonable efforts to cause to be obtained
as much of such insurance coverage as can be obtained for the remainder of such
six-year period for an annualized premium not in excess of the Maximum Premium.
 
NASDAQ LISTING
 
     It is a condition to the consummation of the Mergers that the shares of
Holdco Common Stock to be issued in connection with the Mergers shall have been
approved for listing on Nasdaq, subject only to official notice of issuance.
 
APPRAISAL OR DISSENTERS' RIGHTS
 
     Holders of NACT Common Stock are not entitled to appraisal or dissenters'
rights in connection with the NACT Merger.
 
EXCHANGE OF SHARES
 
     At or prior to the NACT Effective Time, World Access will appoint, and will
retain for a period of at least six months after the NACT Effective Time, an
exchange agent (the "NACT Exchange Agent") to effect the exchange of shares of
NACT Common Stock for Holdco Common Stock in connection with the NACT Merger.
From time to time after the NACT Effective Time, World Access shall deposit or
cause to be deposited, certificates representing Holdco Common Stock for
conversion of shares of NACT Common Stock in accordance with the NACT Merger
Agreement.
 
     Commencing immediately after the NACT Effective Time and until the
appointment of the NACT Exchange Agent is terminated, each holder of a
certificate or certificates theretofore evidencing shares of NACT Common Stock
may surrender the same to the NACT Exchange Agent, and, after the appointment of
the NACT Exchange Agent has been terminated, any such holder may surrender any
such certificate to Holdco. Such holder will be entitled upon such surrender to
receive in exchange therefor a certificate or certificates representing the
number of full shares of Holdco Common Stock into which the shares of NACT
Common Stock theretofore represented by the certificate or certificates so
surrendered have been converted pursuant to the NACT Merger, together with a
cash payment in lieu of fractional shares, if any, and all such shares of Holdco
Common Stock will be deemed to have been issued at the NACT Effective Time.
Until so surrendered and exchanged, each outstanding certificate which, prior to
the NACT Effective Time, represented issued and outstanding shares of NACT
Common Stock will be deemed for all corporate purposes of Holdco, other than the
payment of dividends and other distributions, if any, to evidence ownership of
the
 
                                       34
<PAGE>   45
 
number of full shares of Holdco Common Stock into which the shares of NACT
Common Stock theretofore represented thereby have been converted at the NACT
Effective Time.
 
     Until certificates representing shares of NACT Common Stock are
surrendered, no dividend or other distribution, if any, payable to the holders
of record of Holdco Common Stock as of any date subsequent to the NACT Effective
Time will be paid to the holder of such certificate. Upon the surrender of any
such certificate representing shares of NACT Common Stock, however, the record
holder of the certificate or certificates representing shares of Holdco Common
Stock issued in exchange therefor will receive from the NACT Exchange Agent or
from Holdco, as the case may be, payment of the amount of dividends and other
distributions, if any, which as of any date subsequent to the NACT Effective
Time and until such surrender will have become payable with respect to such
number of shares of Holdco Common Stock. No interest will be payable with
respect to the payment of any such presurrender dividends upon the surrender of
certificates theretofore representing shares of NACT Common Stock.
 
     No fractional share certificates for Holdco Common Stock will be issued
upon the surrender for exchange of certificates evidencing shares of NACT Common
Stock. In lieu thereof, the NACT Exchange Agent or Holdco, as the case may be,
will pay each holder of NACT Common Stock an amount in cash calculated as
provided in the NACT Merger Agreement.
 
     Risk of loss and title to certificates representing shares of NACT Common
Stock will pass only upon proper delivery of such certificates to the NACT
Exchange Agent.
 
     World Access will deposit, or cause to be deposited, certificates
representing Holdco Common Stock for conversion of shares of NACT Common Stock
in accordance with the NACT Merger Agreement.
 
     At the NACT Effective Time, the stock transfer books of NACT with respect
to shares of NACT Common Stock will each be closed, and there will be no further
registration of transfers of shares of NACT Common Stock thereafter on the
records of any such stock transfer books. In the event of a transfer of
ownership of shares of NACT Common Stock that is not registered in the stock
transfer records of NACT, at the NACT Effective Time, a certificate or
certificates representing the number of full shares of Holdco Common Stock into
which such shares of NACT Common Stock have been converted will be issued to the
transferee, together with a cash payment in lieu of fractional shares, if any,
and a cash payment in the amount of any presurrender dividends, if any, if the
certificate or certificates representing such shares of NACT 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.
 
     AT THE EFFECTIVE TIME OF THE MERGERS, EACH CERTIFICATE REPRESENTING
OUTSTANDING SHARES OF WORLD ACCESS COMMON STOCK WILL, WITHOUT ANY ACTION ON THE
PART OF THE HOLDER THEREOF, BE DEEMED TO REPRESENT AN EQUAL NUMBER OF SHARES OF
HOLDCO COMMON STOCK.
 
     HOLDERS OF WORLD ACCESS COMMON STOCK SHOULD NOT SUBMIT CERTIFICATES
REPRESENTING THEIR SHARES OF WORLD ACCESS COMMON STOCK FOR EXCHANGE.

THE MERGERS
 
     Pursuant to the NACT Merger Agreement and on the terms and subject to the

closing of the Mergers (the "Closing") will take place on a date to be specified
by the parties, which shall be no later than the second business day after
satisfaction of the conditions described in the first paragraph under
"-- Conditions to the Mergers" below (the "Closing Date"). The Mergers will

the Secretary of State of the State of Delaware with respect to both the NACT
Merger and the World Access Merger. The time at which the NACT Merger becomes
effective is referred to as the "NACT Effective Time." The time at which the

     At the Effective Time of the Mergers, pursuant to the NACT Merger Agreement
(i) each issued and outstanding share of World Access Common Stock, other than
shares held directly or indirectly by World Access, will be converted into one
share of Holdco Common Stock, and upon such conversion all such shares of World
Access Common Stock will be canceled and retired and will cease to exist, and
(ii) all shares of World Access Common Stock held by World Access will be
canceled and retired and will cease to exist without payment of any
consideration therefor.
 
     AT THE EFFECTIVE TIME OF THE MERGERS, EACH CERTIFICATE REPRESENTING

CONVERSION OF NACT COMMON STOCK
 
     At the Effective Time of the Mergers, pursuant to the NACT Merger Agreement
(i) each issued and outstanding share of NACT Common Stock, other than shares
held directly or indirectly by World Access or Holdco or in the treasury of
NACT, will be converted into the right to receive shares of Holdco Common Stock
equal to the quotient of (x) $17.50 divided by (y) the World Access Average
Closing Price, unless the World Access Average Closing Price exceeds $25.52 per
share, in which event each outstanding share of NACT Common Stock will be
converted into 0.6857 shares of World Access Common Stock, and upon such
conversion all such shares of NACT Common Stock will be canceled and retired and
will cease to exist, and (ii) all shares of NACT Common Stock held by NACT will
be canceled and retired and will cease to exist without payment of any
consideration therefor. Notwithstanding the foregoing, if the World Access

terminate the NACT Merger Agreement. See "-- Termination of NACT Merger
Agreement."
 
     HOLDERS OF NACT COMMON STOCK SHOULD NOT SEND ANY CERTIFICATES REPRESENTING

Common Stock. Following the Effective Time of the Mergers, each such option or
warrant will continue to have, and will be subject to, the same terms and
conditions as in effect immediately prior to the Effective Time of the Mergers,
except that each option to purchase shares of NACT Common Stock shall be
exercisable for that number of shares of Holdco Common Stock equal to the
product of the number of shares of NACT Common Stock for which such option was
exercisable immediately prior to the Effective Time of the Mergers multiplied by
the NACT Exchange Ratio, and the exercise price per share of such option will be
equal to the aggregate exercise price of such option immediately prior to the

Stock for which such option will be exercisable immediately after the Effective
Time of the Mergers.

                            BUSINESS OF WORLD ACCESS
 
     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.
 
     World Access markets and sells its products and services to over 200
telecommunications service providers. Its customers include all of the regional
Bell companies, including BellSouth, SBC Communications, Bell Atlantic and
NYNEX; other local exchange carriers such as Century Telephone, Alltel and
Puerto Rico Telephone; inter-exchange carriers such as Sprint and Cable &
Wireless; wireless service providers such as Cellular One, Comcast Cellular and
Price Cellular; and other service providers entering the telecommunications
industry such as competitive access providers, cable television companies and
private network operators.
 
     From May 1995 to August 1997, World Access acquired five telecommunications
products businesses: AIT, Inc. ("AIT"), a full-service provider of Northern
Telecom switching systems, frames and related circuit boards; Westec
Communications, Inc. ("Westec"), a provider of microwave and millimeterwave
systems and services for voice, data and video applications; Sunrise Sierra,
Inc. ("Sunrise"), a developer and manufacturer of intelligent transport and
access products; Cellular Infrastructure Supply, Inc. ("CIS"), a provider of
equipment and related design, installation and technical support services to the
cellular and PCS markets; and Galaxy Personal Communications Services, Inc.
("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. These five acquisitions (the
"Acquisitions") broadened World Access' line of products, enhanced its product
development capabilities and strengthened its ability to provide complete
telecommunications network solutions to its customers.
 
     World Access has 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 97.2% in 1995, 69.2% in 1996
and 82.3% in 1997. 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 76.8% of total sales in 1997, its
gross profit margin increased from 12.9% in 1994 to 21.1% in 1995, 29.4% in 1996
and 34.6% in 1997. As a percentage of total sales, World Access' operating
income (loss) increased from (8.5%) in 1994 to 5.0% in 1995, 14.4% in 1996 and
21.0% in 1997.
 
     Although World Access has aggressively pursued acquisitions in recent
years, approximately 50% of its 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 its ability
to provide working capital, an extensive base of telecommunications customers
and a broad range of support services.

<PAGE>   55
 
     World Access' objective is to continue to broaden its offering of wireline
and wireless switching, transport and access products and expand its geographic
market coverage to become a preferred provider of telecommunications products
and related services. In order to achieve this objective, World Access plans to
continue its strategy of (i) acquiring switching, transport and access products
companies; (ii) developing proprietary products; (iii) pursuing opportunities to
license and manufacture telecommunications products; (iv) leveraging its
existing customer relationships and distribution base; (v) focusing on emerging
international markets; and (vi) leveraging World Access' manufacturing, test and
service capabilities.
 
     On January 29, 1998, World Access acquired 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 video
applications.
 
     On May 12, 1998, World Access announced that it had entered into the
Resurgens Merger Agreement and the Exchange Agreement. 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.
 
     On June 4, 1998, World Access announced that it had entered into the Telco
Merger Agreement. Telco is a manufacturer of broadband transmission products,
network access products and bandwidth optimization products for network
services. It had net sales of approximately $117.8 million for its fiscal year
ended August 31, 1997 and $81.6 million for the nine months ended May 31, 1998
and incurred a net loss of $1.1 million for the year ended August 31, 1997 and
$2.9 million for the nine months ended May 31, 1998.
 
     World Access' principal executive offices are located at 945 East Paces
Ferry Road, Suite 2240, Atlanta, Georgia 30326. Its telephone number is (404)
231-2025.

                                BUSINESS OF NACT
 
     NACT provides advanced telecommunication switching platforms with
integrated applications software and network telemanagement capabilities. NACT
designs, develops and manufactures all hardware and software elements necessary
for a complete fully integrated, turnkey telecommunications switching solution.
Its customers do not require the multiple suppliers of hardware and value added
resellers of software that would otherwise be necessary to provide a wide range
of services and applications. NACT's customers include national and
international long distance carriers, prepaid debit card and prepaid cellular
network operators, international call back/reorigination providers and other
specialty telecommunications service providers.
 
     NACT's products and services include the STX application switching
platform, the NTS telemanagement and billing system (the "NTS"), facilities
management services, and selling and servicing LCXs. The STX (the "STX") is an
integrated digital tandem switching system that currently supports up to 1,344
ports per switch and can be combined with two additional STXs to provide a total
capacity of 4,032 ports per system. The STX 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 has targeted the STX, with its enhanced features and
scaleable capacity, to an expanded group of customers, including independent
telephone companies, Competitive Access Providers ("CAPs")/ Competitive Local
Exchange Carriers ("CLECs"), shared tenant service providers, Fortune 1000
corporations and local telephone companies within and outside the United States.
The NTS performs call rating, accounting, switch management, invoicing and
traffic engineering for multiple switches that may either be NACT switches or a
number of other industry switches. In conjunction with the sale of a system,
NACT offers a facilities management service whereby NACT will operate and
maintain a customer's switch for a fee. In providing this service, NACT enables
its customers to direct their attention toward marketing their products rather
than initially focusing on the technical aspects of operating a switch.
 
     On July 1, 1997 NACT completed the planned move of its corporate
headquarters and manufacturing facilities from Orem, Utah to Provo, Utah. The
new building was paid for from the proceeds of NACT's initial public offering
completed in March 1997. The new facility has increased NACT's manufacturing
capabilities by approximately 300%. NACT's former corporate headquarters and
manufacturing facility was being leased on a month-to-month basis.
 
     In fiscal 1997, NACT opened new sales and technical support offices in
Florida, New York and the United Kingdom. NACT made its first international
sales of its STX and NTS products in the fiscal fourth quarter of 1997.
 
INDUSTRY BACKGROUND
 
     Deregulation of long distance phone service in 1984 opened competition in
the telecommunications market to companies such as MCI Communications, Inc.
("MCI"), Sprint Corporation ("Sprint"), WorldCom and many smaller specialty
services providers. Today, there are over 450 long distance companies in the
United States according to the FCC. In addition to basic long distance calling
(1+), many of these companies are providing high value added, specialty long
distance products such as international call back/ reorigination, prepaid debit
card and prepaid cellular to differentiate their services from each other and to
generate higher margin revenue than basic long distance phone services can
provide.
 
     International call back/reorigination.  International call
back/reorigination companies provide least-cost long distance calling services
from one foreign country to another through the use of a switch located in the
United States that takes advantage of the lower rate per call charged in the
United States. NACT believes that as deregulation takes place in specific
countries, international call back/reorigination providers will be positioned
for additional opportunities to provide direct dial international calling by
virtue of their established customer base.
 
     Prepaid debit cards/Prepaid cellular.  Prepaid debit cards allow users to
make long distance calls from any touch tone phone based on a given number of
minutes that have been credited to the card. Prepaid debit card applications
include promotional campaigns, fund raising for charitable organizations and
budgeted out-
 
                                       46
<PAGE>   57
 
of-town calling for travelling employees. In addition, prepaid debit cards allow
long distance companies to generate revenues from a base of customers who would
otherwise not have the opportunity to take advantage of long distance services
due to credit and other considerations. An emerging application in the prepaid
market is prepaid cellular, a service whereby cellular phone users can limit
their monthly dollar usage automatically in the same manner that a prepaid debit
card limits the time a user can call. NACT believes that the potential prepaid
cellular market is not currently being effectively addressed in the United
States. The potential market consists of a large number of potential users who
either are denied traditional cellular service due to lack of credit or need to
limit the usage of cellular service. Prepaid cellular offers a way to capture
revenue from these potential subscribers.
 
     1+.  One plus is a dialing method that enables equal access to telephone
networks by all service providers offering direct dial long distance, whether
inside or outside of a caller's own area code. This protocol also enables the
introduction of telephone exchanges with the same three digits as area codes.
The 1+ market is comprised of both large global companies, including MCI,
Sprint, AT&T and WorldCom and smaller, entrepreneurial long distance providers
that are either facilities based or switchless. Historically, these smaller
specialty services providers have competed exclusively based on price. However,
NACT believes that these companies are competing increasingly based on their
ability to provide enhanced services as well as on price.
 
     As long distance service providers have increasingly offered enhanced
services to their customers, demand for these services has also increased in the
local exchange market. Competitors such as CAPs, CLECs, cellular and Personal
Communications Services Providers ("PCS"), specialized mobile radio companies
and, more recently, cable television providers have begun rapidly deploying
enhanced services and providing cost effective interfaces to long distance
carriers. In addition, the Telecommunications Act of 1996 allows CLECs to
compete with the incumbent Local Exchange Carrier ("LEC") (generally, the RBOC
or GTE) for basic local telephone service. Additionally, demand for enhanced
services is expected to increase internationally as new service opportunities
result from the combination of privatization of previously government-owned
telecommunications systems, competition created in these international markets
and the creation of services in developing countries with typically low
densities of telephones.
 
     NACT believes that companies competing in this new environment require
switching platform systems that are flexible to meet the diverse requirements of
an expanding array of applications. These systems must be compatible with the
variety of transmission technologies utilized by telephone companies and must be
capable of processing multiple concurrent services. In order to provide enhanced
services to end users, a provider must purchase (i) one or more applications
switch platforms, (ii) software applications to run the switches and provide
system functionality and (iii) a billing system. Historically, an entrepreneur
interested in entering the international call back/reorigination, prepaid debit
card and prepaid cellular markets had to purchase each of these components from
a separate vendor. Customers who purchase components from different sources
must, either on their own or through the services of a consultant, configure the
disparate components and provide for the system's maintenance and upgrading.
This requires a significant expenditure of time and money, limits
interoperability and technology upgrading, and diverts company resources. NACT
believes that in today's market environment its customers require solutions that
allow quick, easy entry into the market, flexibility to add new services and
additional capacity, high reliability and low cost.
 
THE NACT SOLUTION
 
     NACT provides its customers with a complete, integrated package consisting
of both the application platform hardware and the operations application
software necessary to provide a full array of intelligent network services. NACT

that integrates all of these components into one comprehensive package that
includes a broad range of applications, competitive pricing, interoperability
and scaleable port capacity. NACT sells its products to long distance carriers,
international call back/reorigination providers, prepaid debit card and prepaid
cellular network operators and other specialty telecommunications service
providers.

service multiple STXs and to add redundancy to the network. NACT has targeted
the STX to an expanded group of customers, including larger enhanced long
distance providers, independent telephone companies, CAPs/CLECs, shared tenant
service providers, Fortune 1000 corporations and local telephone companies in
other countries. NACT believes that its STX switching platform meets or exceeds
the scaleability, performance, interoperability and reliability standards of
this expanded customer base. NACT believes that the STX offers value added
features and capacity at price points typically below those offered by its
competitors.
 
     The STX application switching platform was designed as a hardware platform
for the enhanced service features that are delivered by NACT's own suite of
applications software. The STX platform consists of a digital tandem switch that
currently supports up to 1,344 ports per switch. It is a single chassis design
with dual disk drives or RAID mass storage, digital audiotape (DAT) or digital
linear tape (DLT) back-up, console and dual modems. The simplicity of its design
makes it a reliable hardware platform to which enhanced telecommunications
service features can easily be added by software. The STX platform has also been
designed so that users can easily replace boards by hotswapping them, a process
that does not require the user to shut down or temporarily disable the switching
system.
 
     The STX applications switching platform has a cost-effective design
incorporating only three types of boards, CPU, T-1 and DSP, and a chassis with a
backplane that supports 2,048 time slots. The current CPU board is powered by a
33 MHz Motorola 68040 processor and contains 64 or 128 megabytes of RAM, a
SCSI-2 peripheral interface, two ARCnet LAN controllers (backplane and external
for communication with the MCU and other STX switches), eight RS-232 serial
ports and alarm LEDs and external relays. The T-1 board is powered by a Motorola
processor and has two megabytes of RAM, an ARCnet LAN controller, and eight T-1
interface controllers that handle 192 ports. The DSP board uses a Motorola
processor with eight megabytes of RAM, an ARCnet controller, three DSP
processors (96 or 120 channels of tone decoding or encoding) and a 64-channel
audio device for the playback of integrated audio messages or the temporary
recording of audio. Each DSP board may cache up to seven megabytes of
frequently-used audio phrases, regardless of language. All boards have been
designed with low-cost components.
 
     The STX hardware platform can operate on a standalone basis with a port
capacity of 1,344. NACT's 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 and future NTS 2000
billing systems.
 
     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
                                       48
<PAGE>   59
 
interfaces, call re-origination, and integrated audio with twenty three
languages. Interoperability enables several applications packages to be used in
conjunction with each other. For example, a prepaid, international call back
call can be assisted by a live operator and rated as a prepaid,
operator-assisted, international call back call. Almost all features are
implemented in software, allowing unlimited capability for enhancement and
customization.
 
     The Master Control Unit allows interconnectivity between multiple NACT STX
platforms and permits database information to become centralized by connecting
co-located NACT systems. Interconnectivity permits expanded carrier call
routing. With more ports available due to the MCU, the likelihood of a caller
receiving a "system busy" signal is essentially eliminated. Downtime of a single
switch has minimal caller impact when proper carrier management is used.
 
     The STX architecture allows configurations from 24 to 1,344 ports in a
single chassis. The MCU allows up to three STX platforms to use a single, common
database and to appear as a single applications system of up to 4,032 ports with
common control of required features such as concurrency checking and fraud
minimization. This performance is achieved using the current Motorola 68040 CPU
board. With a new CPU board under development by NACT, incorporating a Motorola
68060 microprocessor, the STX and MCU systems will achieve the full capacity of
their architectures of 2,048 and 8,192 ports, respectively.
 
     The STX applications platform with the Motorola 68040 CPU board can process
eight million call minutes per month in a 1,024 port nonblocked configuration.
The Motorola 68060 processor will increase capacity to 16 million call minutes
in a 2,048 port nonblocked configuration. By linking four STXs with the MCU,
capacity is expected to increase to 64 million call minutes per month using the
Motorola 68060 CPU board.
 
     The STX applications platform has been developed to allow multiple
application packages to run simultaneously and in a seamless fashion. An example
would be a client wishing to use international call back/ reorigination, with
the assistance of an operator to place the call, and the cost of the call being
debited from the client's prepaid calling account. Virtually all features are
implemented in the software allowing unlimited capability for enhancement and
customization.
 
     The STX applications platform is designed using digital components and is
capable of running on single or redundant power supplies. When multiple STX
platforms are placed under the control of an MCU, the failure of a single STX
platform is handled through carrier routing of calls into the remaining STX
systems. With the introduction of the redundant MCU feature, the failure of a
single STX will not compromise the routing of calls through the system.
 
     NTS BILLING SYSTEM.  The 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 LCX application platforms, and can rate all types of call traffic and, using
a sophisticated rating engine, provides 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, ANIs, accounts receivable, and management
of delinquent accounts. A major feature of the NTS 1000 is its switch management
capability. When coupled with the STX and LCX application platforms, information
that has been entered into the NTS 1000 can be electronically transferred into
these systems, thereby minimizing data entry needs. This integrated
communication between the NTS 1000 and the LCX and STX also allows for automatic
disabling of authorization codes or ANIs when credit limits are exceeded. 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.
 
     The NTS 1000 system uses high performance Pentium Pro servers using RAID
and error correcting code (ECC) memory with the option of adding additional
processors. It uses SCO's latest Unix offering, 5.0.4, which supports multiple
processors and has full LAN support and enhanced Unix graphical user interface
 
                                       49
<PAGE>   60
 
(GUI) system administration tools. The NTS 1000 uses Unify's relational database
management system (RDBMS) for storage of information and for screen entry and
reports. Access to the application can be either through a LAN using a terminal
emulation package on PCs or using terminals connected directly through RS-232
ports.
 
     The NTS 2000 is NACT's next generation billing system. This system is a
state-of-the-art product incorporating leading edge technology and data
processing techniques. This new product integrates the popular features and
functionality of NACT's existing NTS 1000 billing system with the following
major enhancements: real time data processing, including call collection and
call rating; user friendly graphical user interface (GUI); open system
connectivity, which allows integration with other information systems; enhanced
security; and audit trails of user activity. This new system utilizes Informix's
industry standard On-Line Dynamic Server RDBMS, which provides for expanded
growth and also takes advantage of multiprocessor configurations. The new GUI
screens provide an advanced user interface, which dramatically increases user
productivity by consolidating operational, and management needs and providing an
environment that is user friendly and intuitive. The NTS 2000 has additional
functionality, including support of 20 digit authorization code numbers,
complete support of international rating, real time credit limit checks, and
real-time customer support management.
 
     The NTS 2000 has been released to multiple customers on a beta test basis
during the first and second quarter of calendar 1998 and is projected to be
released for general sale during the first quarter of calendar 1999.
 
     LCX SWITCHING SYSTEM.  Prior to introducing the STX, NACT's principal
product was the LCX applications platform, which has a maximum capacity of 480
ports in a single cabinet configuration. While NACT continues to sell
refurbished LCXs and support users of LCXs, NACT does not plan to manufacture
additional LCXs or develop ongoing enhancements for the LCX. The versatility of
the LCX, which was designed to operate in an unattended environment, enables it
to provide, in an integrated fashion, the following applications: long distance;
pay phone or courtesy phone network management; international call back/
reorigination; and prepaid debit card. During the introduction of the STX, NACT
offered an option to customers of the LCX to return their LCX system in exchange
for a discount on their purchase of an STX system. NACT refurbished and resold
the returned LCX systems, which were attractive to customers with lower capacity
and feature requirements. The reliability of the LCX enabled the system to be
easily refurbished by general cleaning and functional testing procedures. The
system was then upgraded to the latest LCX configuration, including both
hardware and software, and made ready for shipment to customers.
 
SERVICES
 
     NACT offers facilities management services to its customers who do not have
or plan to hire technical operators. This service allows the customer to
concentrate on marketing its products while NACT operates and maintains its
switch for a fee. NACT offers facilities management services to facilitate sales
of its switches. NACT also provides competitively priced domestic and
international network services to its customers, thereby facilitating their
smooth entry into the communications business. Through the aggregation of
customer traffic, NACT has negotiated favorable carrier rates from the major
interexchange carriers. Currently, the switch room that houses a customer's
equipment is located at NACT's headquarters in Provo, Utah.
 
CUSTOMERS
 
     NACT's applications platforms and billing systems have been accepted in a
variety of segments of the telecommunications industry and serve a broad array
of domestic and international applications. To date, NACT estimates that it has
installed over 500 application switching and billing systems.
 
     NACT's customers are diverse and represent many different aspects of the
telecommunications industry. These customers have implemented a wide variety of
features on the STX switching platform and NTS billing system, including prepaid
debit card, international call back, operator services, prepaid cellular and
other applications for specialty markets.
                                       50

SALES AND MARKETING
 
     NACT primarily sells its products through a direct sales force located at
its headquarters and through remote sales offices in New York, Florida and
London. NACT's marketing strategy is to generate leads through attendance at
trade shows, advertising in industry periodicals and referrals from existing
customers. NACT convenes annual two-day round table discussions for its
customers. NACT invites its customers to meet in an environment of cooperation
and collaboration to discuss their experiences with NACT's products, providing
significant consideration for future NACT product development and enhancement.
 
     NACT has established a sales presence in the United Kingdom and plans to
establish a sales presence in other countries it believes to be strategically
advantageous. NACT believes that a sales organization that understands and can
solve complex switching and network management and billing systems requirements
is necessary to sell its products to specialty telecommunications network
service providers and corporate end users. NACT intends to invest significantly
to enlarge its sales organization in order to expand its customer base.
 
     NACT expects that its technical support organization and customer referrals
will continue to be an important factor in NACT's sales. In attempting to
broaden its customer base, NACT will be marketing its products and services to
larger telephony providers whose procurement processes are generally more
protracted and may be expected to require additional effort on NACT's part.
 
     During the fourth quarter of fiscal 1997, NACT sold its first STX switching
and NTS billing systems outside the United States. NACT believes that there is
substantial opportunity for future growth in the international market,
particularly in the developing countries and in countries in which the
telecommunications industry is being deregulated. NACT intends to address these
opportunities by creating an international sales force and by marketing its
products through international partners directly involved in telecommunications
equipment sales.
 
TECHNICAL SUPPORT
 
     NACT's technical support staff provides business consulting as well as
trouble-shooting services to its customers. NACT's customers operate in an
environment in which reliability and availability of technical support are
increasingly critical factors. Such value-added services have resulted in a
recurring stream of revenues for NACT.
 
     NACT's technical support department installs and supports systems sold by
NACT and provides ongoing services that include training, business
consultations, trouble-shooting and upgrades. Since NACT sells a single
switching solution that includes essentially all of the key elements a customer
needs to offer enhanced services, a customer need not look beyond NACT, its
"single source," for its technical switching solutions.
 
     The technical support department is involved with a customer as soon as a
sale has been finalized. A detailed pre-installation checklist is completed with
the customer prior to installation. A technical support engineer installs the
equipment at the customer's location, configures software for the specific
applications to be utilized and brings up the telephone circuits. Typically, a
system is operational shortly after it is delivered.
 
     After the equipment is installed, NACT's technical support department works
with the customer to keep the equipment functioning reliably. Modem access to
all customer equipment enables NACT's technical support personnel to perform
diagnostics, trouble-shoot equipment, perform software upgrades, transmit
programs and configure hardware from a remote location. In addition, technical
support provides consulting services on network issues and additional
applications.
 
     To quickly and efficiently resolve customer issues, the technical support
department uses an automated tracking system that contains the complete
installed customer database, software and hardware configuration, site
addresses, contacts and modem phone numbers. An incoming customer call is
monitored on this system, and the status of the resolution of the customer
problem and the mean-time to repair are updated and maintained for reporting
back to the customer. An incident escalation procedure ensures that all customer
problems receive appropriate visibility until a solution has been achieved. The
technical support department
 
                                       51
<PAGE>   62
 
maintains 24-hour, 7-day-a-week emergency service coverage. NACT's equipment is
warranted for one year, after which the customer pays an annual fee for factory
support. Factory support includes toll free telephone support, as well as all
operating system software upgrades and free board repair. These upgrades allow
NACT's customers to take advantage of software enhancements offered by NACT.
 
     NACT's main technical support operations are located at its headquarters.
NACT has also established technical support satellite offices in New York,
Florida and the United Kingdom. NACT plans to expand the department into several
key locations in conjunction with the opening of additional sales offices.
 
RESEARCH AND DEVELOPMENT
 
     NACT's research and development efforts are focused on the development of
both new products (not based on existing core technologies) and the addition of
new features and capabilities to its existing suite of products. The research
and development department continually works to improve the quality of NACT's
products and to ensure that such products meet industry standards and government
regulations. In addition, NACT is working toward the successful development of
new products that will enable it to offer additional intelligence to a
customer's existing network. During the past 16 years, NACT's engineers have
introduced seven hardware platforms, 10 software applications, 20 international
language software packages and numerous enhancements to such products.
 
     NACT is working to increase the port capacity of the STX and to improve and
supplement its enhanced services and its billing system platform. NACT is
incorporating the Motorola 68060 CPU board into the STX application platform to
enable the STX to support 2,048 ports per chassis or 8,192 ports per integrated
MCU system. With the Motorola 68060 processor, the STX is expected to process up
to 16 million call minutes per month in a 2,048 port nonblocked configuration or
can be combined with three additional STXs to provide up to 64 million call
minutes per month.
 
     NACT is currently developing an improved billing system, the NTS 2000,
which is being designed for real time transaction processing and which will use
a graphical user interface and improved call reports and will allow for greater
customization of invoices, bills and reports. NACT expects that the NTS 2000
will be available for use with its applications platform switches in the third
quarter of calendar 1998 and will be available for use with non-NACT switches in
the future. The "server" side of the NTS 2000 will use one or more Pentium Pro
file-server systems with the SCO UNIX operating system and an Informix database
management system. The "client" side will use a PC computer with the Windows 95
operating system. All processing will be based upon real time transaction
processing.
 
     The telecommunications equipment market is characterized by rapidly
changing technologies and frequent new product introductions. The rapid
development of new technologies increases the risk that current or new
competitors could develop products that would reduce the competitiveness of
NACT's products. NACT's success will depend to a substantial degree upon its
ability to respond to changes in technology and customer requirements. This will
require the timely selection, development and marketing of new products and
enhancements on a cost-effective basis. The development of new, technologically
advanced products is a complex and uncertain process, requiring high levels of
innovation. Further, the telecommunications industry is characterized by the
need to design products that meet industry standards for safety, emissions and
network interconnection. With new and emerging technologies, such standards are
often changing or unavailable. As a result, there is a potential for product
development delay due to the need for compliance with new or modified standards.
The introduction of new and enhanced products also requires that NACT manage
transitions from older products in order to minimize disruptions in customer
orders, avoid excess inventory of old products and ensure that adequate supplies
of new products can be delivered to meet customer orders.
 
     As of September 30, 1998, 29 full-time employees were engaged in research
and development. NACT spent approximately $1,183,000, $1,352,000 and $2,385,000
on research and development during the fiscal years ended September 30, 1995,
1996 and 1997, respectively. NACT expects that it will continue to expend
significant resources for product research and development.
 
                                       52

MANUFACTURING AND QUALITY ASSURANCE
 
     NACT's manufacturing operations consist primarily of material requirements
planning, material procurement and final assembly, test and quality control of
subassemblies and completed systems. NACT outsources its printed circuit board
assembly. NACT believes that by outsourcing its printed circuit board assembly,
NACT gains flexibility in the manufacturing process and achieves lower direct
labor and overhead costs. NACT currently conducts its manufacturing operations
in its new manufacturing facility in Provo, Utah in a space of approximately
10,000 square feet.
 
     NACT utilizes an annual planning forecast, which is modified monthly, to
determine its material and outsourcing requirements. NACT orders materials with
differing lead times, generally 30 to 180 days in advance. NACT uses
"just-in-time" ordering of materials that are readily available to minimize
inventory carrying costs. NACT's systems are manufactured to a standard
configuration that allows for better production planning, lower direct labor and
overhead costs and shorter order-to-shipment times.
 
     NACT tests its systems in accordance with NACT-designed quality control
specifications that are consistent with ISO 9000 requirements. 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.
 
     ISO 9000 certification is a three step process: writing a "quality manual"
in accordance with the ISO 9000 requirements; documenting the processes and
procedures used to design, build, sell and finance products; and being audited
by an official ISO 9000 registrar. NACT has completed the "quality manual," is
currently documenting the processes and procedures and has selected an ISO 9000
registrar to conduct the certification audit. In conjunction with ISO 9000
certification, NACT presently has an in-house quality inspection program where
it tests all products prior to shipment to ensure the highest standard of
quality.
 
     NACT primarily uses standard parts and components for its products,
procured from multiple vendors. Certain integrated circuits, card cage chassis
and billing system database software are presently available only from a limited
source of supply. To date, NACT has been able to obtain adequate supplies of
these components in a timely manner.
 
COMPETITION
 
     The market for switching equipment and network management and billing
systems is highly competitive, and NACT expects competition to increase in the
future. The market is subject to rapid technological change, regulatory
developments in the telecommunications industry and emerging industry standards.
NACT believes that the primary competitive factors in the market for switching
equipment and network telemanagement and billing systems are the development and
rapid introduction of new product features, price/performance, reliability and
quality of customer support. NACT believes that it competes across three
categories, PC Based Switch Platforms, Open Architecture (Programmable) Hardware
Platforms, and Application Switch Platforms.
 
     A PC-based switch platform is a personal computer, usually with high
capacity, that contains generic telephony boards for interfacing with the public
network. A typical platform provides a single application such as debit card or
international call back/reorigination, which are software applications that can
be brought to market rapidly. Leading providers of these types of switches are
Communications Product Development, Inc., Integrated Telephoning Products, Inc.
and PCS Telecom, Inc. The users of this equipment generally tend to be start-up
operations that are concerned about initial equipment costs and that are
generally able to bring software solutions to the market rapidly. While these
users may feel that PC-based solutions are relatively low cost, as their
business grows, it becomes apparent that these systems are costly to expand on a
cost per port basis and offer few features that are standard with switch-based
platforms. Additionally, PC-based systems are not regarded as a viable solution
for larger users due to their reliability concerns.
 
     A programmable hardware platform generally consists of proprietary switch
hardware, together with the necessary software to provide a programming
application interface (API) that allows other computers executing third-party
application software to control the calls within the switch hardware. Leading
providers of
                                       53
<PAGE>   64
 
these types of switches are Summa Four, Inc., Excel, Inc. and Redcom
Laboratories, Inc. and the value-added software providers that support this type
of hardware, such as Magellan Network Systems, Inc., Boston Technology, Inc. and
Open Development Corporation. The users of this type of equipment tend to be
companies that have the ability and desire to write their own applications code
or are willing to purchase their applications code from a specialized third
party developer.
 
     An application switching platform is an integrated hardware/software
switching system that contains software applications that perform basic 1+ and
operator assisted services over the public network. To provide intelligent
functionality, an adjunct switch must be connected to the application switch
platform. Leading providers of application switch platforms are Harris
Corporation and Siemens Stromberg Carlson. The major users are companies that
are established in their telephony business such as 1+ providers that now need
to expand their offerings to their customers to remain competitive in the
marketplace. Enhanced services are particularly attractive to these customers
and play a large part in their decision making process.
 
     As NACT's business develops and it seeks to market its switches to a
broader customer base, NACT's competitors may include larger switch and
telecommunications equipment manufacturers such as Lucent Technologies Inc.,
Harris Corporation, Siemens AG, Alcatel Alsthom Compagnie, Generale
D'Electricite, Telefonaktiebolaget, L.M. Ericcson and Northern Telecom Ltd. Many
of NACT's current and potential competitors have substantially greater
technical, financial, manufacturing and marketing resources than NACT.
 
INTELLECTUAL PROPERTY AND OTHER PROPRIETARY RIGHTS
 
     NACT's success is dependent in part on intellectual property rights,
including information technology, some of which is proprietary to NACT. NACT
relies on a combination of copyright, trade secret and trademark law,
confidentiality procedures and other contractual restrictions to establish and
protect proprietary rights in its products and technologies. As part of these
confidentiality procedures, NACT generally enters into confidentiality and
non-disclosure agreements with its employees and limits access to and
distribution of its proprietary information. NACT has received federal trademark
applications for the marks STX and NTS 2000 and is currently conducting a review
of its products to determine for which products it will seek patent, trademark
or copyright registration protection. NACT currently licenses certain technology
from third parties and plans to do so in the future.
 
EMPLOYEES
 
     As of September 30, 1998, NACT had 115 full-time employees, of whom 29 were
engaged in research and development, 19 in manufacturing and quality control, 11
in sales and marketing, 29 in technical support, 14 in operations and management
information systems, and 13 in administration and finance. None of NACT's
employees is represented by a collective bargaining agreement nor has NACT
experienced any work stoppage. NACT considers its relations with its employees
to be good.
 
PROPERTIES
 
     NACT's headquarters and manufacturing facility, which is located in Provo,
Utah, is a newly-constructed building that NACT moved into on July 1, 1997. The
Utah facility was constructed for a cost of about $4.1 million and was paid for
from the proceeds of NACT's initial public offering.
 
     NACT also has sales and technical support offices located in New York, New
Jersey, Florida and London, England. These offices are leased by NACT under
leases that expire at various dates through 1998. Annual lease payments of these
offices aggregate approximately $30,000.
 
     With the exception of the office furnishings held under an operating lease,
NACT owns the equipment and furnishings located in all of its facilities.
 
     NACT considers all of its properties, both owned and leased, together with
the related equipment and furnishings contained therein, to be well maintained,
in good operating condition and suitable for its present and foreseeable future
needs.

CERTAIN LEGAL PROCEEDINGS
 
     On August 24, 1995, 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"). The initial complaint further alleged defamation and unfair
competition as a result of a communication disseminated by NACT to its customers
and tortious interference with prospective business relations, alleging that
NACT induced third parties to abandon licensing negotiations with Aerotel.
Aerotel sought injunctive relief, damages in an unspecified amount, damages of
up to three times the 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 judgment 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 and GST USA, as well as Kyle
Love, the former President of NACT, and Dr. Thomas E. Sawyer, a director of GST
and NACT and the former Chairman and Chief Executive Officer 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. The defendants have served answers denying all
material allegations and intend to defend vigorously.
 
     Under the terms of World Access' stock purchase agreement with GST, World
Access and GST have agreed to share evenly the costs of any judgment against
NACT as a result of the Aerotel litigation, including NACT's legal fees.
Subsequent to the NACT acquisition, World Access has been actively engaged in
settlement negotiations. On July 9, 1998, World Access, GST and Aerotel entered
into a Memorandum of Understanding to settle the Aerotel litigation, and the
parties are negotiating the terms and conditions of a final settlement
agreement. World Access currently estimates that its portion of the settlement
costs, including legal fees, will be approximately $3.3 million and will be paid
through the issuance of World Access Common Stock. If a settlement does not
occur, NACT's patent counsel believe that NACT has valid defenses to the Aerotel
claims (which, if upheld, would be valid for all defendants), and the defendants
intend to vigorously defend. However, no assurances can be given as to the
outcome of this action. An unfavorable decision in this action could have a
material adverse effect on Holdco's business, financial condition and results of
operations.

                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
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, 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 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, 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
 
                                       56
<PAGE>   67
 
$10.0 million, respectively. As a result of this initial public offering, GST's
interest in NACT was reduced to approximately 63%.
 
     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. See "Summary -- World Access' Interest in NACT."
 
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
 
                                       57
<PAGE>   68
 
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 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.
 
                                       58
<PAGE>   69
 
     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 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
 
                                       59
<PAGE>   70
 
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
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
 
                                       60
<PAGE>   71
 
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.

1998, respectively.
 
                                       61
<PAGE>   72
 
     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 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
 
                                       62
<PAGE>   73
 
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 COMPLIANCE
 
     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.

               UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS
 
     The following Unaudited Pro Forma Combined Financial Statements of Holdco
give effect to the consummation of the Transaction and to the several
transactions that Holdco has completed or are currently contemplated. The
Unaudited Pro Forma Combined Statements of Operations give effect to: (1) the
ATI acquisition; (2) the NACT Stock Purchase; (3) the NACT Transaction; (4) the
Resurgens Transaction; and (5) the Telco 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 Telco
Merger as if they had been completed on June 30, 1998.
 
     As Telco's fiscal year end, August 31, differs from World Access' fiscal
year-end by more than 93 days, Telco's 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's results of operations for the six months from December 1, 1997 through
May 31, 1998 were used in preparing the Unaudited Pro Forma Combined Statement
of Operations for the six months ended June 30, 1998. Telco's 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 Holdco 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 acquisition transaction,
Holdco expects to record charges representing the estimated portion of the
purchase price allocated to in-process research and development of $73.9 million
for the Telco acquisition. In addition, in the six month period ended June 30,
1998, Holdco 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
Holdco 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 also give effect to
Telco's January 1998 acquisition of substantially all of the assets of Jupiter
Technology, Inc. ("Jupiter"), a privately held company engaged in the
development of ATM and frame relay access equipment, as of January 1, 1997. The
purchase price of $6.2 million included approximately $5.1 million of in-process
research and development which was expensed by Telco at the time of such
acquisition. Jupiter's operations were not deemed material when compared to
Telco's historical financial statements and, therefore, were not included in the
Unaudited Pro Forma Combined Statements of Operations. The $5.1 million
in-process development charge recorded by Telco was non-recurring in nature and
excluded from the Unaudited Pro Forma Combined Statement of Operation.
 
     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 Holdco, ATI, NACT and Telco, the historical
combined financial statements of Resurgens and the related notes thereto. See
"Incorporation of Certain Documents by Reference" and "Available Information".

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 Holdco 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, 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
July 9, 1998, World Access, GST and Aerotel entered into a Memorandum of
Understanding to settle the Aerotel litigation. Including legal fees, World
Access now estimates its Aerotel settlement costs will be approximately $3.3
million. The settlement costs expected to be incurred by World Access 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 Holdco 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

   NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
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. 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 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%.

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.  Telco develops and manufactures products focused on providing
integrated access for network services. Telco's products can be separated into
three categories: (1) broadband transmission products, (2) network access
products, and (3) bandwidth optimization products. Telco's 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 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's 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's in process research
and development are expected to include interface support not in Telco's current
product line, including E1, DS3 and OC3.
 
     None of the in-process projects at Telco considered in the write-off are
expected to achieve technological feasibility before the consummation of World
Access' acquisition of Telco. 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's 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's old products by these new products as well as the
expected growth in the overall market in which Telco's 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 (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.

                                     HOLDCO
 
   NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
     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 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. Holdco
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):

     (C) The Resurgens Transaction will be accounted for under the purchase
method of accounting. Holdco 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 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 Holdco 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 Holdco 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. Holdco 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 Holdco common stock [the closing price on
the announcement date was $37.06 and the closing price on August 28, 1998 was
$23.13, a 37.6% reduction]. Management of Holdco 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 Holdco 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.
 
     Specifically, the Escrowed Shares will be released in the amounts and on
the dates specified below if the sum of the EBITDA for Resurgens for the
performance periods set forth below equals or exceeds the Target EBITDA for such
performance period as set forth below:

</TABLE>
 
     Notwithstanding the foregoing, if the Exchange Closing Date is (a) on or
after August 16, 1998 but prior to September 30, 1998, then the First
Performance Period shall commence on September 1, 1998 and shall terminate on
(and including) December 31, 1998 and the Target EBITDA with respect thereto
shall be reduced to $6,700,000, or (b) 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 Holdco 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 is
expected to be confirmed by the bankruptcy court in early September 1998. Upon
the confirmation of the Plan of Reorganization and the closing of the Resurgens
Transaction, the creditors will receive shares of RCG common stock in exchange
for the surrender 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 Holdco 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 Holdco 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 PRO FORMA ADJUSTMENTS
 
     (E) The Telco 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 will be expensed at the consummation
of the acquisition. The amount of the one-time non-recurring charge is expected
to approximate $73.9 million. Since this charge is directly related to the
acquisition and will not recur, the Unaudited Pro Forma Statements of Earnings
have

     (i) Based on the terms of the Telco Merger Agreement and the value of World
Access Common Stock as of August 28, 1998, Telco stockholders are currently
expected to receive approximately 6.5 million freely tradeable shares of Holdco
common stock at the time of the Telco Merger. The value assigned to these shares
will be $29.26 per share, the seven trading days average closing price of World
Access Common Stock which include the three trading days prior and the three
trading days subsequent to June 4, 1998, the date economic terms of the Telco
Merger were announced.
 
     (ii) The net deferred tax asset of $16 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
and Holdco. It is the opinion of management that these tax assets are likely to
be utilized by Telco or Holdco.
 
     (iii) The value of the acquired technology of $56.4 million is based on a
preliminary valuation report prepared by an independent appraiser and represents
the value of Telco's current technology calculated using the income approach.
 
     (iv) The amount of in-process research and development costs of $73.9
million is based on 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. Holdco will obtain an updated
valuation of the in-process research and

                      DESCRIPTION OF HOLDCO CAPITAL STOCK
 
GENERAL
 
     Holdco is authorized to issue 40,000,000 shares of common stock, par value
$.01 per share (the "Holdco Common Stock"), and 10,000,000 shares of preferred
stock, par value $.01 per share (the "Preferred Stock").
 
HOLDCO COMMON STOCK
 
     The holders of Holdco 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 Holdco Common Stock can elect
all members of Holdco's board of directors, and holders of the remaining shares
by themselves cannot elect any member of the board of directors.
 
     The holders of Holdco 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 Holdco,
the holders of Holdco 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 Holdco Common Stock. Holders of shares of Holdco Common Stock, as such,
have no conversion, preemptive or other subscription rights, and there are no
redemption provisions applicable to the Holdco Common Stock. All of the
outstanding shares of Holdco Common Stock are fully paid and nonassessable.
 
PREFERRED STOCK
 
     The Holdco board of directors is authorized, without stockholder approval,
to issue from time to time up to 10,000,000 shares of 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 Certificate of Incorporation. To date, no
series of Preferred Stock has been authorized or issued. Holdco has no present
plans to issue any shares of Preferred Stock.
 
     The issuance of shares of Preferred Stock by action of the Holdco board of
directors could adversely affect the voting power, dividend rights and other
rights of holders of Holdco Common Stock. Issuance of shares of a series of
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 Holdco board of directors is required to make a
determination as to the best interests of Holdco's stockholders when issuing
shares of 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 Holdco
or in which stockholders might receive a premium for their Holdco Common Stock
over the then-prevailing market price. Although there are currently no plans to
issue shares of Preferred Stock or rights to purchase such shares, Holdco
believes that the availability of the 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
Preferred Stock are available for issuance without further action by Holdco's
stockholders, unless such action is required by applicable law or the rules of
any stock exchange on which the Holdco Common Stock may then be listed.
 
DELAWARE BUSINESS COMBINATION STATUTE
 
     Section 203 of the DGCL provides that, subject to certain exceptions
specified therein, 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 date, the board of directors of the
corporation approved either the business combination or the transaction
                                       94
<PAGE>   105
 
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) on or subsequent to such date,
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, 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. Holdco has not elected
to be exempt from the restrictions imposed under Section 203. The provisions of
Section 203 may encourage persons interested in acquiring Holdco 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 Holdco. It is possible that such
provisions could make it more difficult to accomplish transactions which Holdco
stockholders may otherwise deem to be in their best interests.
 
LIABILITY OF DIRECTORS
 
     The Holdco Certificate provides that a director of Holdco will not be
personally liable to Holdco 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 Holdco 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 Holdco Common Stock will be Continental Stock
Transfer & Trust Company, 2 Broadway, New York, New York 10004.
 
        COMPARISON OF RIGHTS OF STOCKHOLDERS OF WORLD ACCESS AND HOLDCO
 
     Holdco and World Access are both organized under the laws of the State of
Delaware. The certificate of incorporation and bylaws of Holdco are the same in
every material respect to the certificate of incorporation and bylaws of World
Access.
 
            COMPARISON OF RIGHTS OF STOCKHOLDERS OF NACT AND HOLDCO
 
     Both Holdco and NACT are incorporated in Delaware. As a result of the NACT
Merger, holders of NACT Stock will become stockholders of Holdco and the rights
of all such former NACT stockholders will be governed by the Holdco Certificate,
the Bylaws of Holdco (the "Holdco Bylaws") and the DGCL. The rights of the
holders of NACT Stock are presently governed by the certificate of incorporation
of NACT (the "NACT Certificate"), the Bylaws of NACT (the "NACT Bylaws") and the
DGCL. The following summary, which does not purport to be an exhaustive
statement of the general differences among the rights of the
 
                                       95
<PAGE>   106
 
stockholders of NACT and Holdco, sets forth a summary comparison of material
differences between the NACT and Holdco Certificates and between the NACT and
Holdco Bylaws. The information set forth below is qualified in its entirety by
reference to the full text of the NACT and Holdco Certificates and the NACT and
Holdco Bylaws.
 
CLASSES AND SERIES OF CAPITAL STOCK
 
     Holdco.  The Holdco Certificate authorizes the issuance of 40,000,000
shares of common stock, $.01 par value per share, and 10,000,000 shares of
preferred stock, $.01 par value per share ("Holdco Preferred Stock"). The Holdco
board of directors has the authority to issue the Holdco Preferred Stock in one
or more series and to fix the rights, preferences, privileges and restrictions
for such series without any further vote or action by the Holdco stockholders.
 
     NACT.  The NACT Certificate authorizes the issuance of 25,000,000 shares of
common stock, $.10 par value per share, and 10,000,000 shares of Preferred
Stock, $.10 par value per share. As of the NACT Record Date, 8,133,830 shares of
NACT Common Stock and no shares of NACT Preferred Stock were outstanding. There
were no options outstanding to purchase shares of NACT Common Stock. The NACT
board of directors has the authority to issue the NACT Preferred Stock in one or
more series and to fix the rights, preferences, privileges and restrictions for
such series, without any further vote or action by the NACT stockholders.
 
BOARD OF DIRECTORS
 
     Election.  The NACT Certificate provides that the election of directors
need not be by written ballot unless the bylaws so provide, and the NACT Bylaws
do not so provide. No other significant prescriptions are listed. On the other
hand, the Holdco Certificate contains more detail concerning the make-up,
election and operation of the Holdco board of directors. For example, the Holdco
board of directors must consist of no fewer than three and not more than 12
members, as fixed by the most recent board of directors. The Holdco board of
directors currently consists of five directors, which will not change as a
result of the Mergers. Additionally, the Holdco board of directors is divided
into three classes; that is, it is a "staggered board," because only
approximately one-third of the board of directors is elected in any one year.
Finally, Holdco stockholders wishing to nominate directors at the annual meeting
where directors are elected must give notice to Holdco at least 120 days prior
to the meeting.
 
     Liability and Indemnification.  The NACT and Holdco Certificates both limit
the liability of directors to the fullest extent possible under the DGCL. The
Bylaws of NACT and the Holdco Certificate also indemnify directors to the
fullest extent possible under applicable law.
 
AMENDMENT TO CERTIFICATE OF INCORPORATION AND BYLAWS
 
     Both the NACT and Holdco Certificates provide that the board of directors
may amend the bylaws of the corporation. Under the DGCL, amending a
corporation's certificate of incorporation generally requires the approval of
the holders of a majority of the outstanding capital stock entitled to vote,
unless the certificate or bylaws provide otherwise. The NACT Certificate
requires the approval of 66 2/3% of the total voting power of all outstanding
shares of capital stock to alter, amend or repeal Articles Seventh, Tenth,
Eleventh and Twelfth (providing for removal of directors only for cause, the
taking of stockholder action only at a meeting, director exculpation and
amending the NACT Certificate). The Holdco Certificate, on the other hand,
requires the approval of 75% of the voting power of all outstanding shares of
capital stock entitled to vote in an election of directors, voting as a single
class, to alter, amend or repeal Article VII of the Certificate. Article VII of
the Holdco Certificate addresses the management of the corporation and sets
forth certain details concerning the operation of the board of directors, the
material aspects of which are discussed above.

                          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

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
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.
 
     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.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  (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 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.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  (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 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.

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.

     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

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.

     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

(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 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.

     SECTION 2.1.  Conversion of Sub-1 Stock and World Access Stock.  Subject to
the terms and conditions of this Agreement, as of the Effective Time and by
virtue of the World Access Merger and without any further action on the part of

     receive and be exchangeable for one share of common stock, $.01 par value
     per share (the "Holdco Stock"), of Holdco (the "World Access
     Consideration"); and
 
          (c) each share of Sub-1 Stock issued and outstanding immediately prior

     nonassessable share of common stock, par value $.01 per share, of the World
     Access Surviving Corporation.
 
     SECTION 2.2.  Conversion of Sub-2 Stock and NACT Stock.  Subject to the

     converted solely into the right to receive and become exchangeable for that
     number of shares of Holdco Stock equal to the quotient of (x) $17.50
     divided by (y) the Closing Date Market Price (the "Exchange Ratio");
     provided, however, that (i) if the Closing Date Market Price is less than

     and (ii) if the Closing Date Market Price is more than $25.52, then the
     Exchange Ratio shall be equal to 0.6857 (the number of shares of Holdco

Stock to receive from Holdco cash (without interest) in an amount equal to the

Warrants.
 
     2.4.1. As of the Effective Time, each outstanding option ("World Access

and shall be subject to, the same terms and conditions set forth in the
applicable option plan or warrant plan (the "World Access Plans") pursuant to
which such World Access Option or World Access Warrant was granted, except that
each such World Access Option or World Access Warrant shall be exercisable for
the same number of shares of Holdco Common Stock as the number of shares of
World Access Common Stock for which such World Access Option or World Access
Warrant was exercisable immediately prior to the Effective Time.
 
     2.4.2.  As of the Effective Time, Holdco shall enter into an assumption
agreement with respect to each World Access Option and each World Access
Warrant, which shall provide for Holdco's assumption of the obligations of World
Access under the applicable World Access Plan. Prior to the Effective Time,
World Access shall make such amendments, if any, to the World Access Plans as
shall be necessary to permit such assumption in accordance with this Section
2.4.2.
 
     2.4.3.  It is the intention of the Parties that, to the extent that any
World Access Option constitutes an "incentive stock option" (within the meaning
of Section 422 of the Code) immediately prior to the Effective
                                       A-3
<PAGE>   141
 
Time, such World Access Option shall continue to qualify as an incentive stock
option to the maximum extent permitted by Section 422 of the Code, and that the

the conditions of Section 424(a) of the Code.
 
     SECTION 2.5.  Exchange Ratio for NACT Options.
 
     2.5.1. As of the Effective Time, each option ("NACT Option") to purchase
NACT Common Stock then outstanding shall be assumed by Holdco and converted into
an option to purchase shares of Holdco Common Stock, as provided below.
Following the Effective Time, each NACT Option shall continue to have, and shall
be subject to, the same terms and conditions set forth in the applicable option
plan (the "NACT Plans") pursuant to which such NACT Option was granted, except
that (i) each such NACT Option shall be exercisable for that number of shares of
Holdco Stock equal to the product of (x) the number of shares of NACT Stock for
which such NACT Option was exercisable immediately prior to the Effective Time
and (y) the Exchange Ratio, rounded in the case of any NACT Option other than
any incentive stock option, up and, in the case of any incentive stock option,
down to the nearest whole share, if necessary, and (ii) the exercise price per
share of such NACT Option shall be equal to the aggregate exercise price of such
NACT Option immediately prior to the Effective Time divided by the number of
shares of Holdco Stock for which such NACT Option shall be exercisable as
determined in accordance with the preceding clause (i), rounded up to the next
highest cent, if necessary.
 
     2.5.2. As of the Effective Time, Holdco shall enter into an assumption
agreement with respect to each NACT Option, which shall provide for Holdco's
assumption of the obligations of NACT under the applicable NACT Plan. Prior to
the Effective Time, NACT shall make such amendments, if any, to the NACT Plans
as shall be necessary to permit such assumption in accordance with this Section
2.5.2.
 
     2.5.3.  It is the intention of the Parties that, to the extent that any
NACT Option constitutes an "incentive stock option" (within the meaning of
Section 422 of the Code) immediately prior to the Effective Time, such NACT
Option shall continue to qualify as an incentive stock option to the maximum
extent permitted by Section 422 of the Code, and that the assumption of the NACT
Option provided by this Section 2.5 shall satisfy the conditions of Section
424(a) of the Code.
 
                                   ARTICLE 3.

     3.1.1.  At or prior to the Effective Time, Holdco shall appoint an agent
reasonably satisfactory to World Access and NACT (the "Exchange Agent") for the
purpose of exchanging certificates representing outstanding shares of World
Access Stock and NACT Stock as provided herein. As of the Effective Time, Holdco
will deposit with the Exchange Agent, in trust for the benefit of holders of
shares of World Access Stock and NACT Stock, certificates representing the
shares of Holdco Stock issuable pursuant to Section 2.1 hereof. Holdco agrees to
make available to the Exchange Agent, from time to time as needed, cash
sufficient to pay cash in lieu of fractional shares pursuant to Section 2.3

     3.1.2.  As promptly as practicable after the Effective Time, the Exchange
Agent shall send or cause to be sent to each former holder of record of shares
of World Access Stock and NACT Stock transmittal materials (the "Letter of
Transmittal") for use in exchanging their certificates formerly representing

this Agreement. The Letter of Transmittal will contain instructions with respect
to the surrender of certificates representing World Access Stock and NACT Stock
and the receipt of the Merger Consideration contemplated by this Agreement and
will require each holder of World Access Stock and NACT Stock to transfer good
and marketable title to such World Access Stock and NACT Stock to Holdco, free

to the stockholders of World Access and NACT, as appropriate. The Exchange Agent
shall, as promptly as practicable after the Effective Time, send or cause to be
sent to each former holder of record of World Access
 
                                       A-4
<PAGE>   142

NACT shall be closed as to holders of World Access Stock and NACT Stock
immediately prior to the Effective Time, and no transfer of World Access Stock
and NACT Stock by any such holder shall thereafter be made or recognized and
each outstanding certificate formerly representing World Access Stock and NACT
Stock shall, without any action on the part of any holder thereof, no longer
represent World Access Stock and NACT Stock. If, after the Effective Time,
certificates are properly presented to the Exchange Agent, such certificates
shall be exchanged for the Merger Consideration contemplated by this Agreement
into which the World Access Stock and NACT Stock represented thereby were
converted in the Mergers.
 
     SECTION 3.2.  Lost Certificates.  In the event that any holder of World
Access Stock and NACT Stock is unable to deliver the certificate which
represents such holder's World Access Stock or NACT Stock, Holdco, in the
absence of actual notice that any World Access Stock or NACT Stock theretofore
represented by any such certificate has been acquired by a bona fide purchaser,
may, in its sole discretion, deliver to such holder the Merger Consideration
contemplated by this Agreement to which such holder is entitled in accordance
with the provisions of this Agreement upon the presentation of all of the
following:
 
          (a) an affidavit or other evidence to the reasonable satisfaction of
     Holdco that any such certificate has been lost, wrongfully taken or
     destroyed;
 
          (b) such security or indemnity as may be reasonably requested by
     Holdco to indemnify and hold Holdco harmless; and
 
          (c) evidence to the satisfaction of Holdco that such holder is the
     owner of World Access Stock or NACT Stock theretofore represented by each
     certificate claimed by such holder to be lost, wrongfully taken or
     destroyed and that such holder is the Person who would be entitled to
     present each such certificate for exchange pursuant to this Agreement.
 
     SECTION 3.3.  Payment to Another Person.  In the event that the delivery of
any Merger Consideration contemplated by this Agreement is to be made to a
Person other than the Person in whose name any certificate representing World
Access Stock or NACT Stock surrendered is registered, such certificate so
surrendered shall be properly endorsed (or accompanied by an appropriate
instrument of transfer), with the signature(s) appropriately guaranteed, and
otherwise in proper form for transfer, and the Person requesting such delivery
shall pay any transfer or other taxes required by reason of the delivery to a
Person other than the registered holder of such certificate surrendered or
establish to the satisfaction of Holdco that such tax has been paid or is not
applicable.
 
     SECTION 3.4.  Right to Receive the Merger Consideration Only.  Until
surrendered in accordance with the provisions of this Article 3, each
certificate representing World Access Stock and NACT Stock shall represent for
all purposes the right to receive the appropriate Merger Consideration
contemplated by this Agreement and shall not represent the right to receive any
other consideration.
 
                                   ARTICLE 4.
 
                     REPRESENTATIONS AND WARRANTIES OF NACT

the Disclosure Schedule delivered by NACT to World Access prior hereto (the

organization, has all requisite power and authority to own, operate and lease
its properties and to carry on its business as it is now being conducted, and is
qualified or licensed to do business and is in good standing in each
jurisdiction in which the nature of the business conducted by it or the

than
 
                                       A-5
<PAGE>   143
 
where failure to be so qualified or licensed, individually or in the aggregate,
would not have an NACT Material Adverse Effect. NACT is not in violation of any
provision of its certificate of incorporation or bylaws or other organizational
documents, as the case may be. NACT has no subsidiaries or equity investments in
any other Person.
 
     SECTION 4.2.  Capitalization.  As of the date of this Agreement, the
authorized capital stock of NACT consists in its entirety of 25,000,000 shares

of NACT Stock are issued and outstanding, (ii) no shares of NACT Preferred Stock
are outstanding, and (iii) options to acquire 1,039,065 shares of NACT Stock are

charter or bylaws or any agreement to which NACT is a Party or by which NACT is
bound. Except as set forth in this Section 4.2, there are no options, warrants
or other rights (including registration rights), agreements, arrangements or
commitments of any character to which NACT is a Party relating to the issued or
unissued capital stock of, or other interest in, NACT or obligating NACT to
grant, issue or sell any shares of capital stock of, or other interest in, NACT
by sale, lease, license or otherwise.
 
     SECTION 4.3.  Authority Relative to this Agreement.  NACT has all requisite
corporate power and authority to execute and deliver this Agreement, to perform
its obligations hereunder and to consummate the transactions contemplated on its
part hereby to be consummated by NACT. The execution and delivery of this
Agreement by NACT and the consummation of the transactions contemplated on its
part hereby have been duly authorized by all necessary corporate action, and,
other than the approval of NACT's stockholders as provided in Section 7.3
hereof, no other corporate proceedings on the part of NACT are necessary to
authorize the consummation of the transactions contemplated on its part hereby.
This Agreement has been duly executed and delivered by NACT and, assuming the
due authorization, execution and delivery hereof by the other Parties,
constitutes the legal, valid and binding obligation of NACT, enforceable against
NACT in accordance with its terms, except to the extent that such enforceability
may be limited by applicable bankruptcy, insolvency, reorganization or other Law
affecting the enforcement of creditors' rights generally or by general equity
principles.
 
     SECTION 4.4.  No Violation.  The execution and delivery of this Agreement
by NACT do not, the performance by NACT of its obligations hereunder will not,
and the consummation by NACT of the transactions contemplated to be performed by
it hereby will not, (i) violate or conflict with any provision of any Law in
effect on the date of this Agreement and applicable to NACT or by which any of
its properties or assets is bound or to which any of its properties or assets is
subject, (ii) require NACT to obtain any consent, waiver, approval, license or
authorization or permit of, or make any filing with, or notification to, any

rights of, or result in any, termination, amendment, acceleration or
cancellation of, or loss of any benefit or creation of a right of first refusal,
or require any payment under, or result in the creation of a lien or other
encumbrance on any of the properties or assets of NACT pursuant to or under any
provision of any indenture, mortgage, note, bond, lien, lease, license,
agreement, contract, order, judgment, ordinance, NACT Permit (as herein defined)
or other instrument or obligation to which NACT is a Party or by which NACT or
any of its properties is bound or to which any of its properties is subject, or
(v) conflict with or violate the certificate of incorporation or bylaws, in each
case as amended or restated, of NACT, except for any such conflicts or
violations described in clause (i) or breaches, defaults, events, rights of
termination, amendment, acceleration or cancellation, payment obligations or
liens or encumbrances described in clause (iv) that would not have an
 
                                       A-6
<PAGE>   144
 
NACT Material Adverse Effect and except where the failure to obtain such
consents, approvals, authorizations or permits, or to make such filings or
notifications would not, either individually or in the aggregate, prevent NACT
from performing any of its obligations under this Agreement and would not have
an NACT Material Adverse Effect.
 
     SECTION 4.5.  Compliance with Laws.
 
     4.5.1.  As of the date of this Agreement, NACT holds all licenses,
franchises, grants, permits, easements, variances, exemptions, consents,

authorizations (collectively, "NACT Permits") necessary to own, lease and
operate its properties and to carry on its business as it is now being conducted
and is in compliance with all NACT Permits and all Laws governing its business,
except where the failure to hold such NACT Permits or to so comply, individually
or in the aggregate, would not have an NACT Material Adverse Effect.
 
     4.5.2.  No action or proceeding is pending or, to NACT's knowledge,
threatened that may result in the suspension, revocation or termination of any
NACT Permit, the issuance of any cease-and-desist order, or the imposition of
any administrative or judicial sanction, and NACT has not received any notice
from any Governmental Authority in respect of the suspension, revocation or
termination of any NACT Permit, or any notice of any intention to conduct any
investigation or institute any proceeding, in any such case where such
suspension, revocation, termination, order, sanction, investigation or
proceeding would result, individually or in the aggregate, in an NACT Material
Adverse Effect.
 
     SECTION 4.6.  Litigation.  As of the date of this Agreement, except as may
be disclosed in the NACT 10-K (as herein defined) or in reports filed by NACT on
Forms 10-Q or 8-K for periods subsequent to the period covered by the NACT 10-K,
in each case filed prior to the date hereof (such reports and filings, including
the NACT 10-K, collectively, the "NACT Current Reports"), there is no claim,
litigation, suit, arbitration, mediation, action, proceeding, unfair labor
practice complaint or grievance pending or, to NACT's knowledge, investigation
of any kind, at law or in equity (including actions or proceedings seeking
injunctive relief), pending or, to NACT's knowledge, threatened in writing
against NACT or with respect to any property or asset of NACT, except for
claims, litigations, suits, arbitrations, mediations, actions, proceedings,
complaints, grievances or investigations which, individually or in the
aggregate, would not have an NACT Material Adverse Effect. Neither NACT nor any
property or asset of NACT is subject to any continuing order, judgment,
settlement agreement, injunction, consent decree or other similar written
agreement with or, to NACT's knowledge, continuing investigation by, any
Governmental Authority, or any judgment, order, writ, injunction, consent decree
or award of any Governmental Authority or arbitrator, including cease-and-
desist or other orders, except for such matters which would not have an NACT
Material Adverse Effect.

World Access true and complete copies (in each case, as amended) of (i) its
Annual Report on Form 10-K for the year ended September 30, 1997 (the "NACT

the Commission. The reports, statements and registration statements referred to
in the immediately preceding sentence (including any financial statements or

respective times such documents were filed or, as applicable, were effective,
the NACT SEC Filings complied in all material respects with all applicable

subsidiary of Holdco, and the shares of the $.01 par value common stock of
Target ("Target Common Stock") will be converted into and exchanged for shares
of the $.01 par value common stock of Holdco ("Holdco Common Stock"). This
Affiliate Agreement represents an agreement between the undersigned and Holdco
regarding certain rights and obligations of the undersigned in connection with
the shares of Holdco Common Stock to be received by the undersigned as a result
of the Merger.
 
     In consideration of the Merger and the mutual covenants contained herein,
the undersigned and Holdco hereby agree as follows:
 
          1. Affiliate Status.  The undersigned understands and agrees that as
     to Target the undersigned is an "affiliate" under Rule 145(c) as defined in
     Rule 405 of the Rules and Regulations of the Securities and Exchange
     Commission ("SEC") promulgated under the Securities Act of 1933, as amended
     ("1933 Act"), and the undersigned anticipates that the undersigned will be
     such an "affiliate" at the time of the Merger.
 
          2. Covenants and Warranties of Undersigned.  The undersigned
     represents, warrants and agrees that:
 
             (a) The Holdco Common Stock received by the undersigned as a result
        of the Merger will be taken for the undersigned's own account and not
        for others, directly or indirectly, in whole or in part.
 
             (b) Holdco has informed the undersigned that any distribution by
        the undersigned of Holdco Common Stock has not been registered under the
        1933 Act and that shares of Holdco Common Stock received pursuant to the
        Merger can only be sold by the undersigned (i) following registration
        under the 1933 Act, or (ii) in conformity with the volume and other
        requirements of Rule 145(d) promulgated by the SEC as the same now exist
        or may hereafter be amended, or (iii) to the extent some other exemption
        from registration under the 1933 Act might be available. The undersigned
        understands that Holdco is under no obligation to file a registration
        statement with the SEC covering the disposition of the undersigned's
        shares of Holdco Common Stock.
 
          3. Restrictions on Transfer.
 
             (a) The undersigned understands and agrees that stop transfer
        instructions with respect to the shares of Holdco Common Stock received
        by the undersigned pursuant to the Merger will be given to Holdco's
        Transfer Agent and that there will be placed on the certificates for
        such shares, or shares issued in substitution thereof, a legend stating
        in substance:
 
                "The shares represented by this certificate may not be sold,
           transferred or otherwise disposed of except or unless (i) covered by
           an effective registration statement under the Securities Act of 1933,
           as amended, (ii) in accordance with (x) Rule 145(d) (in the case of
 
                                      A-21
<PAGE>   159
 
           shares issued to an individual who is not an affiliate of the issuer)
           or (y) Rule 144 (in the case of shares issued to an individual who is
           an affiliate of the issuer) of the Rules and Regulations of such Act,
           or (iii) in accordance with a legal opinion satisfactory to counsel
           for the issuer that such sale or transfer is otherwise exempt from
           the registration requirements of such Act."
 
             (b) Such legend will also be placed on any certificate representing
        Holdco securities issued subsequent to the original issuance of the
        Holdco Common Stock pursuant to the Merger as a result of any stock
        dividend, stock split, or other recapitalization as long as the Holdco
        Common Stock issued to the undersigned pursuant to the Merger has not
        been transferred in such manner to justify the removal of the legend
        therefrom. If the provisions of Rules 144 and 145 are amended to
        eliminate restrictions applicable to the Holdco Common Stock received by
        the undersigned pursuant to the Merger, or at the expiration of the
        restrictive period set forth in Rule 145(d), Holdco, upon the request of
        the undersigned, will cause the certificates representing the shares of
        Holdco Common Stock issued to the undersigned in connection with the
        Merger to be reissued free of any legend relating to the restrictions
        set forth in Rules 144 and 145(d) upon receipt by Holdco of an opinion
        of its counsel to the effect that such legend may be removed.
 
          4. Understanding of Restrictions on Dispositions.  The undersigned has
     carefully read the Agreement and this Affiliate Agreement and discussed
     their requirements and impact upon the undersigned's ability to sell,
     transfer, or otherwise dispose of the shares of Holdco Common Stock
     received by the undersigned in connection with the Merger, to the extent
     the undersigned believes necessary, with counsel for the undersigned or for
     Target.
 
          5. Filing of Reports by Holdco.  Holdco agrees, for a period of two
     years after the effective date of the Merger, to file on a timely basis all
     reports required to be filed by it pursuant to Section 13 of the Securities
     Exchange Act of 1934, as amended (the "1934 Act"), so that the public
     information provisions of Rule 145(d) promulgated by the SEC, as the same
     are presently in effect, will be available to the undersigned in the event
     the undersigned desires to transfer any shares of Holdco Common Stock
     issued to the undersigned pursuant to the Merger.
 
          6. Transfer Under Rule 145(d).  If the undersigned desires to sell or
     otherwise transfer the shares of Holdco Common Stock received by the
     undersigned in connection with the Merger at any time during the
     restrictive period set forth in Rule 145(d), the undersigned will provide
     the necessary representation letter to the Transfer Agent for Holdco Common
     Stock, together with such additional information as the Transfer Agent may
     reasonably request. If Holdco's counsel concludes that such proposed sale
     or transfer complies with the requirements of Rule 145(d), Holdco shall
     cause such counsel, at Holdco's expense, to provide such opinions as may be
     necessary to Holdco's Transfer Agent so that the undersigned may complete
     the proposed sale or transfer.
 
          7. Acknowledgments.  The undersigned recognizes and agrees that the
     foregoing provisions also apply with respect to Target Common Stock held
     by, and Holdco Common Stock issued in connection with the Merger to, (a)
     the undersigned's spouse, (b) any relative of the undersigned or of the
     undersigned's spouse who has the same home as the undersigned, (c) any
     trust or estate in which the undersigned, the undersigned's spouse, and any
     such relative collectively own at least a 10% beneficial interest or of
     which any of the foregoing serves as trustee, executor or in any similar
     capacity, and (d) any corporation or other organization in which the
     undersigned, the undersigned's spouse and any such relative collectively
     own at least 10% of any class of equity securities or of the equity
     interest. The undersigned further recognizes that, in the event that the
     undersigned is a director or executive officer of Holdco or becomes a
     director or executive officer of Holdco upon consummation of the Merger,
     then, among other things, any sale of Holdco Common Stock by the
     undersigned within a period of less than six months following the effective
     time of the Merger may subject the undersigned to liability pursuant to
     Section 16(b) of the 1934 Act.
 
          8. Miscellaneous.  This Affiliate Agreement is the complete agreement
     between Holdco and the undersigned concerning the subject matter hereof.
     Any notice required to be sent to any party hereunder shall be sent by

             "SECTION 1.4 Charter and Bylaws.  At the Effective Time: (i) with
        respect to the World Access Merger, the certificate of incorporation and
        bylaws of World Access shall be amended at the Effective Time as set

          (b) Section 2.2(b) of the Merger Agreement is hereby amended and
     restated in its entirety as follows:

        solely into the right to receive and become exchangeable for that number
        of shares of Holdco Stock equal to the quotient of (x) $17.50 divided by

February 24, 1998
 
Independent Committee of the Board of Directors
NACT Telecommunications, Inc.
191 West 5200 North
Provo, UT 84604
 
Gentlemen:
 
     We understand NACT Telecommunications, Inc., a Delaware corporation
("Seller"), and World Access, Inc., a Delaware corporation ("Buyer"), propose to
enter into an Agreement and Plan of Merger and Reorganization, dated February
24, 1998, a draft of which has been provided to us by management of Seller (the
"Merger Agreement"), pursuant to which a wholly-owned subsidiary of Buyer will
be merged with and into Seller, which will be the surviving entity (the
"Merger"). Pursuant to the Merger, as more fully described in the Merger
Agreement and as further described to us by management of Seller, we understand
that each outstanding share of the common stock, $.01 par value per share
("Seller Common Stock"), of Seller not owned by Buyer will be converted into and
exchangeable for shares of the common stock, $.01 par value per share ("Buyer
Common Stock"), of Buyer having a value of $17.50 per share based on the Closing
Date Market Price as defined in the Merger Agreement, subject to a collar
described in Section 2.2(b) of the Merger Agreement (the "Consideration"). We
understand that immediately prior to the Merger Buyer will own approximately
67.3% of the outstanding shares of Seller Common Stock. The terms and conditions
of the Merger are set forth in more detail in the Merger Agreement.
 
     You have asked for our opinion as investment bankers as to whether the
Consideration to be received by the stockholders of Seller (other than Buyer)
pursuant to the Merger is fair to such stockholders from a financial point of
view, as of the date hereof. As you are aware, we were not retained to nor did
we advise Seller with respect to alternatives to the Merger or Seller's
underlying decision to proceed with or effect the Merger. Further, we were not
requested to nor did we solicit or assist Seller in soliciting indications of
interest from third parties for all or any part of Seller.
 
     In connection with our opinion, we have, among other things: (i) reviewed
publicly available financial and other data with respect to Seller and Buyer,
including the consolidated financial statements for recent years and interim
periods to December 31, 1997 with respect to Seller and to September 30, 1997
with respect to Buyer, and certain other relevant financial and operating data
relating to Seller and Buyer made available to us from published sources and
from the internal records of Seller and Buyer; (ii) reviewed the financial terms
and conditions of the draft Merger Agreement; (iii) reviewed certain publicly
available information concerning the trading of, and the trading market for,
Seller Common Stock and Buyer Common Stock; (iv) compared Seller from a
financial point of view with certain other companies in the voice switching and
other enhanced voice applications industries which we deemed to be relevant; (v)
compared Buyer from a financial point of view with certain other companies in
the transmission and switching, wireline access and wireless access industries
which we deemed to be relevant; (vi) considered the financial terms, to the
extent publicly available, of selected recent business combinations of companies
in the voice switching and other enhanced voice applications industries which we
deemed to be comparable, in whole or in part, to the Merger; (vii) considered
the premiums paid in comparable public market acquisitions of selected
businesses within the technology industry; (viii) considered the premiums paid
in acquisitions of the remaining publicly-held minority interests by the
majority interest holder; (ix) reviewed and discussed with representatives of
the management of Seller and Buyer certain information of a business and
financial nature regarding Seller and Buyer, furnished to us by them, including
financial forecasts and related assumptions of Seller and Buyer; (x) made
inquiries regarding and discussed the Merger and the draft Merger Agreement and
other matters related thereto with Seller's and Buyer's counsel; and (xi)
performed such other analyses and examinations as we have deemed appropriate.
 
                                       B-1

     In connection with our review, we have not assumed any obligation
independently to verify the foregoing information and have relied on its being
accurate and complete in all material respects. With respect to the financial
forecasts for Seller and Buyer provided to us by their respective managements,
upon their advice and with your consent we have assumed for purposes of our
opinion that the forecasts (including the assumptions regarding operating
synergies) have been reasonably prepared on bases reflecting the best available
estimates and judgments of their respective managements at the time of
preparation as to the future financial performance of Seller and Buyer and that
they provide a reasonable basis upon which we can form our opinion. We have also
assumed that there have been no material changes in Seller's or Buyer's assets,
financial condition, results of operations, business or prospects since the
respective dates of their last financial statements made available to us. We
have relied on advice of counsel and independent accountants to Seller as to all
legal and financial reporting matters with respect to the Merger and the Merger
Agreement. We have assumed that the Merger will be consummated in a manner that
complies in all respects with the applicable provisions of the Securities Act of
1933, as amended (the "Securities Act"), the Securities Exchange Act of 1934 and
all other applicable federal and state statutes, rules and regulations. In
addition, we have not assumed responsibility for making an independent
evaluation, appraisal or physical inspection of any of the assets or liabilities
(contingent or otherwise) of Seller or Buyer, nor have we been furnished with
any such appraisals. You have informed us, and we have assumed, that the Merger
will be recorded as a purchase under generally accepted accounting principles.
Finally, our opinion is based on economic, monetary and market and other
conditions as in effect on, and the information made available to us as of, the
date hereof. Accordingly, although subsequent developments may affect this
opinion, we have not assumed any obligation to update, revise or reaffirm this
opinion.
 
     We have further assumed with your consent that the Merger will be
consummated in accordance with the terms described in the Merger Agreement,
without any further amendments thereto, and without waiver by Seller of any of
the conditions to its obligations thereunder.
 
     In the ordinary course of our business, we actively trade the equity
securities of Seller and Buyer for our own account and for the accounts of
customers and, accordingly, may at any time hold a long or short position in
such securities. We have also acted as an underwriter in connection with
offerings of securities of Seller.
 
     Based upon the foregoing and in reliance thereon, it is our opinion as
investment bankers that the Consideration to be received by the stockholders of
Seller (other than Buyer) pursuant to the Merger is fair to such stockholders
from a financial point of view, as of the date hereof.
 
     We are not expressing an opinion regarding the price at which the Buyer
Common Stock may trade at any future time. The Consideration to be received by
the shareholders of Seller pursuant to the Merger is based upon an exchange
ratio determined on the basis of the market price for Buyer's common stock prior
to the closing subject to a collar, and, accordingly, the market value of the
Consideration may vary significantly.
 
     This opinion is directed to the Independent Committee of the Board of
Directors of Seller in its consideration of the Merger and is not a
recommendation to any stockholder as to how such stockholder should vote with
respect to the Merger. Further, this opinion addresses only the financial
fairness of the Consideration to be received by stockholders of Seller and does
not address the relative merits of the Merger and any alternatives to the
Merger, Seller's underlying decision to proceed with or affect the Merger or any
other aspect of the Merger. This opinion may not be used or referred to by
Seller, or quoted or disclosed to any person in any manner, without our prior
written consent, which consent is hereby given to the inclusion of this opinion
in any proxy statement or prospectus filed with the Securities and Exchange
Commission in connection with the Merger. In furnishing this opinion, we do not
admit that we are experts within the meaning of the term "experts" as used in
the Securities Act and the rules and regulations promulgated thereunder, nor do
we admit that this opinion constitutes a report or valuation within the meaning
of Section 11 of the Securities Act.
 
                                          Very truly yours,

FORWARD LOOKING STATEMENTS
 
     This Form 10-K contains certain forward-looking statements within the
meaning of Section 27A of the Securities Act of 1993, as amended, and Section
21E of the Securities Exchange Act of 1934, as amended, which are intended to be
covered by the safe harbors created thereby. Although the Company believes that
the assumptions underlying the forward-looking statements contained herein are
reasonable, any of the assumptions could be inaccurate, and therefore, there can
be no assurance that the forward-looking statements included in this Form 10-K
will prove to be accurate. Factors that could cause actual results to differ
from the results discussed in the forward-looking statements include, but are
not limited to, the Company's dependence on recently introduced products and
products under development, successful integration of new acquisitions,
competition and the impact of technological change on the Company's products. In
light of the significant uncertainties inherent in the forward-looking
statements included herein, the inclusion of such information should not be

objectives and plans of the Company will be achieved.
 
                                     PART I
 
ITEM 1.  BUSINESS
 
OVERVIEW
 
     The Company develops, manufactures and markets wireline and wireless
switching, transport and access products for the global 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, 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 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.
 
INDUSTRY BACKGROUND
 
     The global telecommunications industry has undergone significant
transformation and growth in recent years due to continued domestic
deregulation, technological innovation and growth in international markets. In
addition, business and residential demand for voice, data and video services has
increased the need for additional systems capacity and network bandwidth to
accommodate the provision of such services by telecommunications providers. The
Company 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 the Company with extensive opportunities
to sell its wireline and wireless switching, transport and access products in
the United States and in international markets.
 
     Domestic Deregulation.  The number of telecommunications service providers
continues to increase as a result of the federal and state deregulation of the
United States telecommunications industry. Changes in federal and state
regulations have created the opportunity for a number of new network operators
to enter the market and have fostered competition between both new and
established network operators. The Telecommunications Act of 1996 permits local
and long distance telecommunications companies, cable television companies and
electric utility companies, subject to certain conditions designed to facilitate
local exchange competition, to compete with each other to provide local and long
distance telephony, data and video services. This Act has also contributed to an
increasing number of mergers and acquisitions among large telecommunications
service providers. As a result, certain providers have changed key network
technology already in place to optimize efficiency and network compatibility.
 
                                       C-1
<PAGE>   174
 
     To accommodate the demand for enhanced wireless services, the Federal
Communications Commission (the "FCC") auctioned additional spectrum licenses for
wireless communications in recent years, potentially increasing the number of
operators competing in each metropolitan statistical area from two to eight. In
addition, the FCC has announced plans to auction additional spectrum in the
future. Changes in FCC and certain state public utility commission regulations
governing interconnections have created opportunities for the Regional Bell
Operating Companies ("RBOCS") and other local exchange carriers to provide
services in markets and geographic regions in which they traditionally have been
prohibited. In addition, such changes have allowed local exchange carriers,
inter-exchange carriers, competitive access providers, cable television
companies and other telecommunications service providers to enter these same
markets and regions. The Company believes that the Telecommunications Act of
1996, together with FCC and other government initiatives, will increase the
demand for telecommunications systems and services as network operators respond
to the changing competitive environment by constructing new or enhancing
existing networks and increasing the available bandwidth to meet customer demand
for voice, data and video services.
 
     Technological Innovation.  In recent years, there have been a number of
significant developments relating to telecommunications technology, including
the continuing miniaturization of large scale integrated circuits, the
development of lower cost, higher capacity memory devices and microprocessors
and new network protocols such as spread spectrum Code Division Multiple Access
("CDMA"), which are now available to offer improved performance and increased
security. These developments have lowered the cost of delivering multifunctional
services combining voice, data and video. In addition, new low cost, modular,
software-driven products (so-called "intelligent" products) can be readily
upgraded to provide additional revenue generating features such as call waiting,
call forwarding and caller-ID without having to undertake costly hardware
replacement. Moreover, the increasing use of wireless systems and technology
permits the more rapid deployment of telecommunications systems at lower costs
than traditional wireline networks.
 
     These technological advances make it possible for products to facilitate
the delivery of telecommunications services and create new network configuration
options. For example, Integrated Services Digital Network ("ISDN") service
allows for the dynamic allocation of bandwidth between, and simultaneous
transmission of, any combination of voice, data and video, and individual call
set-up permits users to easily designate and change the service configuration.
Other new advanced technologies include Asymmetrical Digital Subscriber Line
("ADSL"), a communications technology which permits the transmission of
information at rates up to 50 megabits per second over existing copper wires,
and High-Speed Digital Subscriber Line ("HDSL"), a communications technology
which permits the digital transmission of information over longer distances
without adding signal regenerator equipment. These new technologies create
additional demands for switching systems, intelligent multiplexers and digital
loop carriers. In addition, cable television companies are beginning to expand
beyond one-way broadcast to provide interactive services using high-speed cable
modems and have announced plans to provide telephony and high speed data
services.
 
     Growth in International Markets.  The Company believes that international
markets represent significant opportunities for growth, particularly in Latin
America, the Caribbean Basin and other developing areas. According to industry
sources, a small percentage of businesses and residences throughout Latin
America have basic telephone service. In addition, advances in radio and antenna
technology make it feasible to provide basic communications access with wireline
quality without the construction cost and obstacles associated with establishing
a wireline grid, thereby further encouraging the deployment of
telecommunications networks in developing countries. The governments of a number
of developed and developing countries have privatized their state-owned
telecommunications service providers and have granted licenses to new network
operators to compete with them. In most instances, as part of the privatization,
these governments have imposed service requirements on all network operators,
resulting in an acceleration of capital expenditures on new or expanded network
systems.
 
PRODUCTS AND SERVICES
 
     The Company 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
                                       C-2

customers. To date, a significant portion of the products sold by the Company
has been Northern Telecom switching products and reengineered cellular base
stations and related mobile network equipment. Through acquisitions, technology
license agreements and internal development, the Company expects to manufacture
an increasing proportion of its products in the future.
 
     Switching Products.  The Company markets digital telephone switching
products that are used for local, tandem, toll and cellular applications. The
switches offered by the Company have line capacities ranging from 100 to 120,000
subscribers and 30 to 60,000 inter-exchange trunks. Switching products
historically offered by the Company 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, the Company
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 the Company's acquisition of a majority stake in NACT
Telecommunications, Inc. ("NACT") in the first quarter of 1998 (see "Note N to
the Consolidated Financial Statements"), the Company 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. The Company sells an
optional companion Master Control Unit ("MCU") to integrate and service multiple
STXs and to add redundancy to the network. The Company 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
 
                                       C-3
<PAGE>   176
 
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 the Company's switching products are primarily local
exchange carriers, inter-exchange carriers, competitive access providers,
private network operators and other telecommunications service providers. The
Company 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.  The Company 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. The
Company's 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.
 
     The Company's 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. The Company has recently 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 the Company's acquisition of Advanced TechCom, Inc. ("ATI") in the
first quarter of 1998 (see "Note N to the Consolidated Financial Statements"),
the Company 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 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 the Company's transport products are primarily an RBOC and
private network users. The Company 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.  The Company 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 Cellular Infrastructure Supply, Inc. ("CIS") in the first
quarter of 1997, the Company 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, the Company 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, the Company 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, the
Company reached an agreement in 1997 with another telecommunications equipment
company to private label its point-
 
                                       C-4
<PAGE>   177
 
to-multipoint radio system and exclusively market it within certain Latin
American countries. The current WLL-2000 integrates the Company'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 the Company with an integrated family of
proprietary switching and wireless access products for the international market.
 
     In 1997, the Company also executed a technology licensing agreement that
grants the Company the perpetual right to incorporate spread spectrum 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 patents, all of which address digital data signals
and wireless communication systems. The Company currently intends to use this
technology as the platform for several new products.
 
     As a result of the acquisition of Comtech Sunrise, Inc. ("Sunrise") in
1996, the Company 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). The Company 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 the Company's access products are primarily local exchange
carriers, inter-exchange carriers, competitive access providers, cable
television companies and the United States military. The Company 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.  The Company offers a full range of complementary design,
manufacturing, installation, testing and repair services. The Company 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 the
Company's inventories and management information systems. By providing these
services, the Company believes it is better able to offer its customers more
comprehensive telecommunications solutions.
 
     The Company repairs a broad range of switching and transmission plug-in
circuit boards originally manufactured by other telecommunications equipment
companies. The Company's wireless equipment repair business consists principally
of the repair and upgrade of amplitude modulation equipment typically used by
cable television companies. The Company's 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, the Company completed its acquisition of
Galaxy Personal Communications Services, Inc. ("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 the Company's customers as
they build new, or upgrade existing, telecommunications networks throughout the
world.
 
     Other Products and Services.  The Company's 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 April 13, 1998, the Company's domestic sales and marketing group
consisted of 51 sales professionals and assistants who are divided into
individual sales and marketing teams for each of the Company's 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 the Company's 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, the Company has acquired product sales professionals who have brought
technical product knowledge and long-term customer relationships to the Company.
 
     In 1996, the Company formed a dedicated international sales and marketing
group to pursue the sale of all of the Company's products and services outside
of the United States. With the acquisition of ATI, the Company's international
sales and marketing group has increased substantially. As of April 13, 1998,
this group consisted of 11 sales professionals and assistants. The Company 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 the Company's products and services and receive bid tenders issued
within their territory.
 
     During 1997, the Company's international sales increased to approximately
11.3% of total Company sales as compared to 2.0% in 1996. The Company intends to
continue to focus significant sales and marketing efforts on emerging
international markets.
 
CUSTOMERS
 
     The Company sells its products and services to over 200 telecommunication
service providers, including the RBOCs, other local exchange carriers,
inter-exchange carriers, wireless service providers, competitive access
providers, cable television companies and other telecommunications service
providers. The following table sets forth a representative list of the Company's
major customers and end-users.

     For the year ended December 31, 1997, no customer of the Company
individually accounted for 10.0% of the Company's total sales. The Company's top
10 customers accounted for 44.2% of total sales. For the year ended December 31,
1996, Cable & Wireless accounted for 10.9% of the Company's total sales, and the
Company's top 10 customers accounted for 54.2% of total sales. The Company's
customers typically are not obligated contractually to purchase any quantity of
products or services in any particular period.
 
MANUFACTURING, ASSEMBLY AND TEST
 
     The Company 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 the Company's 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, the Company began
 
                                       C-6
<PAGE>   179
 
utilizing the Company's 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 the Company's internally
developed products, including additional products from the acquisitions of NACT
and ATI, the Company is opening a new manufacturing facility in Alpharetta,
Georgia. The new Alpharetta manufacturing facility is expected to be fully
operational by the end of the second quarter of 1998. It is anticipated that the
existing Orlando facility will be closed during the second quarter as the
Company will no longer service third party contract manufacturing business.
 
     The Company's new Alpharetta manufacturing operation will possess
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. The Company 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 the Company's existing testing
equipment, the new equipment gives the Company 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, the Company is
also taking 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 will move to a new facility in
Orlando. The Company's 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 the Company's circuit board
repair business will be conducted in the new Orlando facility under one
management team.
 
     At ATI's facility in Wilmington, Massachusetts, the Company utilizes
sophisticated RF test and tuning equipment to manufacture and service it
microwave radio systems. In the second quarter of 1998, the Company will
relocate its Westec operations from Scottsdale, Arizona to Wilmington to improve
operating efficiencies and reduce administrative costs.
 
     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.
 
     The Company has an experienced Director of Quality who, along with a staff
of quality assurance professionals, oversees the quality of the Company's
products and services. The Company's Orlando and Wilmington operations are ISO
9002 and ISO 9001 certified, respectively. The Company expects its Alpharetta
and Provo operations to become ISO certified by the end of 1998. 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, the Company
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.
 
     The Company believes that it currently has the equipment, personnel and
experience necessary to efficiently manufacture high quality telecommunications
products in-house. This should assist the Company in controlling the costs,
quality and delivery of its products and allow the Company to bring new products
to market on a timely basis.
 
SUPPLIERS
 
     Products manufactured by the Company 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. The Company purchases electronic components from numerous sources,
including original manufacturers and parts distributors.
 
                                       C-7
<PAGE>   180
 
     The Company 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 the Company's 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, the Company has been able to obtain adequate supplies of
these components. The Company's 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 the Company's
business, financial condition and results of operations.
 
     Although the Company manufactures its own switching products, a significant
portion of the switching products sold to date by the Company 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. The Company currently has formal consignment agreements
with Ameritech, SNET and Century Telephone, pursuant to which the Company
inventories Northern Telecom, Lucent Technologies and other circuit boards for
resale by the Company.
 
ENGINEERING AND DEVELOPMENT
 
     Historically, the Company's engineering, development and technical support
efforts have focused on the repair of switching, transport and access products
and on electronic manufacturing processes. The Company has significant
experience in developing automated test systems, diagnostic programs and repair
procedures for electronic circuitry typically found within telecommunications
switching equipment. The Company's engineers have also used their expertise and
experience to create new revenue sources for the Company by developing upgrades
and enhancements to existing products, including those developed and
manufactured by other telecommunications equipment companies.
 
     During 1997, the Company's 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 the Company's engineering and development capabilities of
switching and transport products with the addition of approximately 46
development engineers. The Company's 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 frequency licensing. The Company 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 April 13, 1998, the Company's engineering and development group
consisted of 121 persons, including 42 RF engineers added through the Galaxy
acquisition, 60 in product development, and 19 in repair service development,
systems integration and manufacturing process and operations support. These
employees are organized into teams corresponding to the Company's product lines,
and each team is responsible for providing technical support to the Company's
customers and for developing and enhancing products. The Company's internal
engineering resources permit the Company to continually reduce the production
cost and improve the functionality of its products.
 
COMPETITION
 
     The segments of the telecommunications industry in which the Company
operates are intensely competitive. The Company's ability to compete is
dependent upon several factors, including price, quality, product features and
timeliness of delivery. Many of the Company's competitors have significantly
more extensive engineering, manufacturing, marketing, financial and technical
resources than the Company. In addition, the Company 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.
 
                                       C-8
<PAGE>   181
 
     In the sale of switching, transport and access products, the Company
competes with companies such as Northern Telecom and Lucent Technologies. The
Company believes it competes favorably against these companies by providing high
quality products, comprehensive support services, competitive prices and
shortened product delivery times. As the Company 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 April 13, 1998, the Company had 510 full-time employees, including
121 in engineering and development, 24 in technical service and support, 62 in
sales and marketing, 139 in manufacturing, warehousing and quality assurance, 92
in repair and refurbishment and 72 in general management, finance,
administration and other support services. From time to time, the Company also
uses part-time employees in its manufacturing operations to accommodate changes
in production levels. None of the Company's employees is represented by any
collective bargaining agreements, and the Company has never experienced a work
stoppage. The Company considers its employee relations to be good.
 
ITEM 2.  PROPERTIES
 
     The Company's executive offices are located in Atlanta, Georgia, where it
occupies approximately 2,000 square feet under a lease expiring in October 1998.
The Company leases certain office, manufacturing and warehouse facilities under

     The Company's existing facilities are adequate for its current operations,
and the Company believes that convenient, additional facilities are readily
available should the business need arise.
 
ITEM 3.  LEGAL PROCEEDINGS
 
     From time to time, the Company is involved in various legal proceedings
relating to claims arising in the ordinary course of its business. Other than
the Aerotel litigation discussed below, neither the Company nor any of its
subsidiaries is party to any such legal proceeding, the outcome of which,
individually or in the aggregate, is expected to have a material adverse effect
on the Company's financial condition or results of operations.
 
     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"). The initial complaint further alleged defamation and unfair
competition as a result of a special report disseminated by NACT to its
customers and tortious interference with prospective business relations,
alleging that NACT induced third parties to abandon licensing negotiations with
Aerotel. Aerotel sought injunctive relief, damages in an unspecified amount,
damages of up to three times the 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
 
                                       C-9
<PAGE>   182
 
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. On May 3, 1996, NACT served its motion for summary
judgement. The court has indicated it will deny such motion, although the actual
ruling has not yet been received. In August 1997, Aerotel amended its complaint
to include as defendants GST Telecommunications, Inc. ("GST"), GST USA, Inc.
("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 officers have served answers
denying all material allegations and intend to defend themselves vigorously.
Pretrial discovery has commenced and is scheduled to be completed in 1998. The
case is not expected to be tried until late 1998 at the earliest.
 
     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, however, could have a material adverse
effect on the Company's financial position.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS
 
OVERVIEW
 
     The Company develops, manufactures and markets wireline and wireless
switching, transport and access products for the global telecommunications
markets. The products offered by the Company include those manufactured by the
Company as well as those manufactured by other telecommunications equipment
manufacturers. 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.
 
     During 1995 and 1996, the Company completed strategic and financial
restructuring programs to strengthen its management team, reposition the Company
as a provider of telecommunications products, improve its financial condition,
reduce its operating costs and position the Company for future growth. These
programs were undertaken following the significant losses incurred by the
Company in the early 1990s, primarily due to a discontinued smart pay telephone
business, and to take advantage of the significant growth opportunities within
the Company's existing customer base and related markets. In November 1994, the
Company began to rebuild its management team and change its strategic focus. The
Company 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 the Company, have brought significant
experience in manufacturing and marketing telecommunications equipment to the
Company.
 
     The Company acquired three businesses in 1995 and 1996 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, the Company acquired AIT, Inc. ("AIT"), a full service provider of
Northern Telecom switching systems, add-on frames and related circuit boards;
effective October 1995, the Company acquired Westec Communications, Inc.
("Westec"), a provider of wireless products and services primarily to the cable
television industry; and effective January 1996, the Company acquired Sunrise, a
developer and manufacturer of intelligent transport and access products.
 
     In January 1997, the Company acquired CIS, a provider of mobile network
equipment and related design, installation and technical support services to
cellular, PCS and other wireless service providers. In August 1997, the Company
acquired Galaxy, an RF engineering firm that provide system design,
implementation, optimization and other value-added radio engineering and
consulting services to the same wireless service markets. The markets served by
CIS and Galaxy complement the Company's traditional telephone service provider
and private network operator markets.
 
     In the first quarter of 1998, the Company 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.
These acquisitions were in line with the Company's strategy to broaden its
offering of proprietary telecommunications equipment and services and position
the Company to engineer, install and support "turnkey" telecommunications
network solutions.
 
     In March 1998, the Company entered into an agreement with a private network
operator based in El Salvador to supply, install and interconnect the
telecommunications equipment necessary to establish and support up to 60,000 new
lines of residential telephone service over the next two years. This agreement
has a potential value to the Company in excess of $20 million. To meet the
Customer's primary network requirements, the Company will utilize the CDX
switch, NTS billing system (NACT), point-to-point microwave radios (ATI) and RF
engineering services (Galaxy).
 
     The Company realized significant improvements in its sales and operating
results since 1994 as a result of the acquisitions and internal growth
initiatives. The Company's total sales increased by 82.3% in 1997, 69.2% in 1996
and 97.2% in 1995. As the Company increased its product sales from 18.2% of
total sales in 1994 to 76.8% of total sales in 1997, its gross profit margin
increased from 12.9% in 1994 to 21.1% in 1995, 29.4% in 1996 and 34.6% in 1997.
As a percentage of total sales, the Company's operating income (loss) increased
from
 
                                      C-13
<PAGE>   186
 
(8.5%) in 1994 to 5.0% in 1995, 14.4% in 1996 and 21.0% in 1997. The Company
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 the Company has aggressively pursued acquisitions in recent years,
over 60 percent of the Company's sales growth during 1995 to 1997 has come from
internal growth initiatives. The Company has had considerable success in growing
businesses post acquisition, most notably AIT and CIS, as a result of its
ability to provide working capital, an extensive base of telecommunications
customers and a broad range of support services.
 
     Since January 1, 1995, the Company 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. The Company has used this capital for acquisitions and to
support the working capital requirements associated with the Company's growth.
The Company's working capital and stockholders' equity have increased from $2.3
million and $1.2 million, respectively, at December 31, 1994 to $153.8 million
and $91.8 million, respectively, at December 31, 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 the Company's 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 the Company's manufacturing
capacity for new Company 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%. The
Company's 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 the Company's establishment
of a dedicated international sales and marketing group and corporate business
development function in March 1996. In addition, the Company 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 the Company, 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%.
 
                                      C-15

     Income Taxes.  The Company's 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 the Company's 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. The Company's 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 the Acquisitions, additional salary and related costs
for the Company's Chairman (who received no salary during 1995) and its new
President, and the Company's 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 the 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.
                                      C-16
<PAGE>   189
 
     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, the Company 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 the Company's 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 the Company's new
bank agreement in March 1996 also contributed to the decrease in interest
expense.
 
     Income Taxes.  The Company's effective income tax rate was 9.9% in 1996.
The Company's 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
the Company's remaining net operating loss carryforward. No income tax expense
was recorded in 1995 due to the partial recognition of benefits associated with
the Company's net operating loss carryforward.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Overview.  Cash management is a key element of the Company's 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 December 31, 1997, the Company had
$118.1 million of cash and equivalents and $10.0 million in borrowings available
under its credit line to support its current working capital requirements and
strategic growth initiatives.
 
     Operating Activities.  Cash used by operating activities was $2.0 million
in 1997 as compared to cash provided by operations of $2.0 million in 1996. The
increased use of cash in 1997 resulted from the Company's need to finance
increased accounts receivable and inventories to support its growth.
 
     Accounts receivable increased $10.6 million, or 109.9%, to $20.3 million at
December 31, 1997 from $9.7 million at December 31, 1996. This was due to the
acquisitions of CIS and Galaxy and increased sales activity at the Company
(fourth quarter 1997 sales were $21.3 million as compared to fourth quarter 1996
sales of $14.6 million). Average days sales outstanding at December 31, 1997
were approximately 81 days as compared to 50 days at December 31, 1996.
 
     Inventories increased $11.8 million, or 110.4%, to $22.4 million at
December 31, 1997 from $10.7 million at December 31, 1996. This increase was due
to the acquisition of CIS, a planned build-up of AIT inventories to support the
increased demand for its switching products and inventories required to support
the roll out of the Company's new products, including the CDX switch, the
WLL-2000 system and the WX-5501 line card.
 
     In addition, the Company shipped approximately $3.8 million of equipment to
Resurgens Communications Group ("Resurgens") in December 1997. On February 12,
1998 the Company executed a letter of intent to acquire Resurgens and therefore
did not record the shipment as a sale. Upon completion of the acquisition of
Resurgens, the equipment will be treated as an investment in Resurgens at the
Company's cost value.
 
     Investing Activities.  Cash used by investing activities, primarily for the
acquisitions of businesses, manufacturing and test equipment and computer
networking equipment was $17.9 million and $1.8 million for 1997 and 1996,
respectively.
 
     Between May 1995 and July 1997, the Company completed the acquisitions of
AIT, Westec, Sunrise, CIS and Galaxy (the "Acquisitions"), which were designed
to bring new wireline and wireless switching, transport and access products and
technology into the Company. All of the Acquisitions were relatively similar in
structure in that the former owners received initial consideration consisting of
a combination of common stock and cash, as well as contingent consideration tied
to the future profitability of the ongoing business. The majority of the
contingent consideration may be paid, at the option of the Company, in the form
of Company
 
                                      C-17
<PAGE>   190
 
common stock valued at its then-current market price. At the time it becomes
highly probable that contingent consideration will be earned, the fair market
value is measured and recorded on the Company's balance sheet as additional
goodwill and stockholders' equity. See Note B to the Consolidated Financial
Statements.
 
     Through December 31, 1997, the Company has paid approximately $8.5 million
in cash consideration in connection with the Acquisitions, including $3.5
million for the CIS acquisition in early 1997, $1.2 million for the Galaxy
acquisition in July 1997 and $3.8 million for the AIT acquisition. The impact of
these payments on the Company's cash position has been partially offset by the
addition of $1.5 million in cash held by Sunrise and Galaxy on the effective
dates of acquisition.
 
     In addition to the $3.5 million in cash paid and 440,874 shares of common
stock issued up front to the CIS stockholders, the stockholders of CIS were
issued 845,010 restricted shares of common stock. These shares were immediately
placed into escrow and, together with $6.5 million in additional purchase price,
will be released and paid to the stockholders of CIS contingent upon the
realization of certain predefined levels of pre-tax income from CIS's operations
during three one-year periods beginning January 1, 1997.
 
     The first measurement period for purposes of releasing escrowed shares and
paying contingent cash 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 this first period would be met. Accordingly, 317,427 escrowed shares
were accounted for as if released and $3.5 million in contingent cash payments
were 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 at April 30, 1997. These shares were released and payment was made
to the former stockholders of CIS on February 15, 1998.
 
     In addition to the $1.2 million in cash and 262,203 shares of common stock
issued up front, 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 redefined levels of pre-tax income
from Galaxy's operations during four measurement periods between July 1, 1997
and December 31, 2000.
 
     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 as of December 31, 1997, the
Company determined that conditions for release and payment for this first period
were met. Accordingly, 15,215 escrowed shares were accounted for as if released
and $400,000 in additional consideration (in the form of 14,901 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 $535,000 at December 31, 1997. These shares were released and
payment was made to the former stockholders of Galaxy on February 15, 1998.
 
     In the fourth quarter of 1997, the Company began its three phase
acquisition of NACT. 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 to the Consolidated Financial Statements.
 
     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 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 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 then 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
                                      C-18
<PAGE>   191
 
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. See Note N to the
Consolidated Financial Statements.
 
     On December 24, 1997, the Company 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 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. See Note N to the
Consolidated Financial Statements.
 
     In December 1997, the Company loaned ATI approximately $4.5 million. ATI
used $2.4 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 the Company's December 31, 1997 balance sheet.
 
     During 1997 and 1996, the Company invested $3.6 million and $1.2 million,
respectively, in capital expenditures. These expenditures were primarily for new
manufacturing and test equipment, computer network and related communications
equipment designed to upgrade the Company's management information systems and
facilitate the integration of the Acquisitions, and facility improvements
required in connection with the Company's growth.
 
     In July 1996, the Company entered into a long-term technology license
agreement with International Communications Technologies, Inc. ("ICT") and Eagle
Telephonics, Inc. ("Eagle") to manufacture, market and sell the CDX, a new
modular, digital central office switch originally developed by Eagle. As
consideration for this license, the Company paid Eagle $250,000 in cash and
provided it with $450,000 of manufacturing services. In addition, the Company
agreed to pay ICT certain royalties based on future sales of the switch by the
Company.
 
     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 CDMA 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 issued
25,000 shares of restricted common stock. These shares had an initial fair value
of approximately $150,000. In addition to the 25,000 shares noted above, the
Company issued 25,000 shares of restricted common stock to TCSI. These shares
were immediately placed in escrow and will be released to TCSI upon the earlier
of the first commercial use of the technology by the Company or the expiration
of the two year period from the date the license was executed.
 
     Financing Activities.  Cash provided from financing activities was $115.4
million and $20.4 million for 1997 and 1996, respectively.
 
     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 in 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 initial purchasers' discount fees of $3.0
million.
 
                                      C-19
<PAGE>   192
 
     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 $14.6 million, after the application of the initial purchasers'
discount fees of $450,000.
 
     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 $3.8 million, net of amortization, are included in Other
assets on the Company's December 31, 1997 balance sheet.
 
     In October 1996, the Company received net cash proceeds of approximately
$25.3 million from the sale of 3,487,500 shares of common stock in a public
offering at a price of $8.00 per share. In October 1996, the Company used
approximately $3.9 million of the net proceeds to repay all amounts borrowed
under its bank term loan. In connection with the repayment of the amounts
borrowed under the term loan, the Company's primary lender increased the amount
available to the Company under its revolving line of credit from $6.0 million to
$10.0 million.
 
     Borrowings under the Company's $10.0 million line of credit 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. As of December
31, 1997, there were no amounts outstanding under the Company's line of credit.
 
     In October 1995, the Company raised approximately $6.5 million through the
exercise of previously-issued warrants and non-qualified options to purchase
shares of common stock. The vast majority of these securities related to
warrants issued in connection with private equity offerings and bank financing
agreements. In exercising their warrants or options, investors had the option of
paying cash or executing an 8% interest-bearing note made payable to the
Company. Approximately $2.4 million of the total proceeds was paid in cash and
$4.1 million through notes, which were paid in full in the first quarter of
1996. There are currently no significant warrants or options outstanding to
purchase common stock except those issued to the Company's directors and
employees. See Note I to Consolidated Financial Statements.
 
     During 1997, the Company received approximately $11.3 million in cash,
including related federal income tax benefits of approximately $6.7 million,
from the exercises of incentive and non-qualified stock options and warrants by
the Company's directors and employees.
 
     Income Taxes.  As a result of the exercises of non-qualified stock options
and warrants by the Company's directors and employees, the Company has realized
a federal income tax benefit of approximately $6.7 million for 1997. Although
this tax benefit does not have any effect on the Company's provision for income
tax expense for 1997, it represents a significant cash benefit to the Company.
This tax benefit is accounted for as a decrease in current income taxes payable
and an increase in capital in excess of par value.
 
     As of December 31, 1997, the Company has capital loss carryforwards of
approximately $1.2 million expiring in 1998.
 
                                      C-20

     Salary Incentive Program.  In December 1996, the Company implemented a
voluntary salary reduction program designed to improve the Company's cash flow
during 1997, further align the objectives of the Company's management and
salaried employees with those of the Company's stockholders and potentially
provide the Company 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 Company 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 the Company 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. The Company's 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.  The Company's improved operating performance and completion of
the sale of $115.0 million of Notes has significantly enhanced its financial
strength and improved its liquidity. As of the date of this Report, the Company
has approximately $60.0 million of cash, no bank debt and a $10.0 million
revolving line of credit available. The Company believes that existing cash
balances, available borrowings under the Company's line of credit and cash
projected to be generated from operations will provide the Company 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 the Company's last eight quarters. This information has been prepared by the
Company on a basis consistent with the Company's audited consolidated financial
statements and includes all adjustments, consisting only of normal recurring
accruals, that the Company 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
the Company's Consolidated Financial Statements and Notes thereto included
elsewhere in this Report.
 
     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.
 
     Sales of switching, transport and access products are subject to the timing
of customer upgrade and new installation programs and, as a result, may
contribute to significant fluctuations in the Company's future quarterly sales.
The Company's operating income performance is also subject to significant
quarterly fluctuations based on the mix of product sales and service revenues.

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 the Company's financial statements.
 
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 the Company's computer
systems that have date sensitive software may recognize a date using "00" as the
year 1900 rather than the year 2000 (the so-called "Year 2000 Issue"). This
could result in a system failure or miscalculations causing disruptions of
operations, including, among other things, a temporary inability to process
transactions, send invoices or engage in normal business activities.
 
     The Company 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 the
Company's computer systems have been put into service within the last several
years, the Company does not expect any such modifications to have a material
adverse effect on the Company's consolidated financial position or results of
operations. There can be no assurance, however, that the computer systems of
other companies on which the Company's systems rely will be timely modified, or
that a failure to modify such systems by another company, or modifications that
are incompatible with the Company's systems, would not have a material adverse
effect on the Company.

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS
 
To the Board of Directors and Stockholders of World Access, Inc.,
 
     In our opinion, the consolidated financial statements listed in the index
appearing under Item 14(a)(1) and (2) on page 55 present fairly, in all material
respects, the financial 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 misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.

                      WORLD ACCESS, INC. AND SUBSIDIARIES
 
                   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
 
                                      C-31

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
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.
 
     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
                                      C-32
<PAGE>   205
                      WORLD ACCESS, INC. AND SUBSIDIARIES
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
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 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
 
                                      C-33

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
$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.
 
     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

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
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.

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.
 
     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
dates indicated.

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
                                      C-37

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").

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     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:

150,000..................................................    4.00     December 15, 1996
</TABLE>
 
     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

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
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 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.

to align director and stockholder long-term interests and to encourage continued
service on the Board. Warrants may be granted under the Warrant Plan only to
directors of the Company who are neither employees of the Company nor of any of
its affiliates. The aggregate number of shares of Company 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 the
Company on or after October 1, 1994 may be granted, in the discretion of the
Board, warrants to purchase no more than 450,000 shares of Company 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 the Company, Messrs.
O'Reilly, Phillips and Raville, each received warrants entitling him to purchase
150,000 shares of 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 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.
 
     Concurrent with the above initial grant, Mr. Clearman, the fourth outside
director of the Company, was awarded warrants to purchase 126,000 shares of
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 awarded Steven A. Odom, who joined the Board in
October 1994 and became Chairman in November 1994, warrants under the Warrant
Plan to purchase 450,000 shares of common stock. The warrants, now fully vested,
entitle Mr. Odom to purchase 450,000 shares of 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.
 
     In December 1994, the Board also adopted the Directors' Warrant Incentive
Plan (the "Incentive Plan") pursuant to which the Board may grant, beginning in
February 1997, to each non-employee 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. No warrants may be granted under the Incentive Plan in a
given year unless the Company's 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 common stock
authorized to be issued pursuant to the Incentive Plan is 600,000 subject to
adjustment in certain instances as described below.
 
     Warrants granted under the Warrant Plan and the Incentive Plan become
exercisable in one or more installments, as the Board 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 for the year in which an installment
first becomes exercisable, then such installment may not be exercised.
 
     On March 26, 1997, the Board granted the four outside Directors of the
Company warrants to each purchase 50,000 shares of common stock with an exercise
price of $9.21. These warrants became fully vested and exercisable on December
31, 1997.
 
     Notwithstanding the foregoing, the Warrant Plan and the Incentive Plan
provide that warrants awarded pursuant to these 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 Company common stock 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 stockholders of the
Company

the liquidation or dissolution of the Company.

SEVERANCE PROTECTION AGREEMENTS
 
     The Company 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 the
Company 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 the Company other than
for "cause" (as defined in the Severence 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 base
salary and bonus and (c) the excess of the actuarial equivalent of retirement
benefits to which the Executive would be entitled under the Company's
supplemental and other retirement plans had the Executive remained in the employ
of the Company 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 the Company 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 and 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 Internal Revenue Code
of 1986, as amended (the "Code"), or would not be deductible by the Company.

ITEM 13.  CERTAIN RELATIONSHIPS AND RELATED 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 to the Company's Consolidated Financial
Statements).
 
     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.

ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS
 
     On January 29, 1998, World Access, Inc. ("World Access"), a Delaware
corporation, consummated the merger (the "Merger") of Advanced TechCom, Inc.
("ATI"), a Delaware corporation, with and into Cellular Infrastructure Supply,
Inc., a Delaware corporation and a wholly-owned subsidiary of World Access
("CIS"), pursuant to that certain Agreement and Plan of Merger dated as of
December 24, 1997 by and between World Access, ATI, CIS and Ernest H. Lin (the
"Merger Agreement").
 
     Pursuant to the Merger Agreement, (i) the issued and outstanding shares of
ATI's Series A Convertible Preferred Stock, $.10 par value per share (the
"Preferred Stock"), were converted into the right to receive (the "Merger Stock
Consideration") an aggregate of 418,100 restricted shares of the common stock,
$.01 par value per share, of World Access (the "World Access Common Stock");
(ii) holders of the issued and outstanding shares of common stock, $.10 par
value per share, of ATI (the "ATI Common Stock") were given a choice to (a)
convert their ATI Common Stock into Preferred Stock on a one-for-one basis and
thereupon receive the Merger Stock Consideration to the same extent as holders
of the Preferred Stock or (b) receive $.01 in cash for each share of ATI Common
Stock not converted (the "Common Stock Consideration"); and (iii), except for
Dr. Lin, who will receive cash and shares of World Access Common Stock in
exchange for his options to purchase ATI Common Stock ("ATI Options"), each
holder of ATI Options that were vested as of December 31, 1997 will be paid in
cash the difference, if any, between $1.00 and the exercise price of such ATI
Option multiplied by the number of shares of ATI Common Stock subject to such
ATI Option (the "Option Consideration," and together with the Merger Stock
Consideration and the Common Stock Consideration, the "Merger Consideration").
In connection with the Merger, Dr. Lin entered into an employment agreement with
CIS, a copy of which is filed herewith as Exhibit 10.1.
 
     In addition, the persons entitled to receive the Merger Stock Consideration
will be entitled to receive up to an aggregate of 209,050 additional restricted
shares of World Access Common Stock payable in installments upon the achievement
by the ATI Division of CIS of certain profitability levels during 1998 and 1999
(the "Contingent Stock Consideration"). Pursuant to the Merger Agreement and
that certain Escrow Agreement (the "Escrow Agreement") entered into at the
closing of the Merger, the Contingent Stock Consideration will be issued and
held in escrow pending its release.
 
     The description contained herein of the Merger Agreement and the Escrow
Agreement is qualified in its entirety by reference to the Merger Agreement and
the Escrow Agreement, which are filed herewith as Exhibits 2.1 and 10.2.
 
     The Merger Consideration and the Contingent Stock Consideration were
determined as a result of negotiations between World Access and ATI and the
Merger was approved by the boards of directors of World Access, CIS and ATI and
the stockholders of ATI. Prior to the Merger, neither World Access nor any of
its affiliates, directors or officers, nor any associate of any such director or
officer, had any relationship with ATI or Dr. Lin, except that World Access
purchased approximately $150,000 of equipment from ATI in 1997 in the ordinary
course of business.
 
ITEM 7.  FINANCIAL STATEMENTS, PRO FORMA FINANCIAL INFORMATION AND EXHIBITS
 
     (a) Financial Statements of Business Acquired.  Included in this Report are
the consolidated financial statements of ATI for the years ended December 31,
1996 and 1995. Such financial statements have been audited by the independent

                          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>
<S>                                                       <C>
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

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
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.

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

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
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, 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:

     The weighted average grant date fair value for options granted in 1996 and
1995 was $.31 and $.67, respectively.
 
     During 1995, the Company's principal stockholder exercised options to
purchase 525,000 shares of common stock by issuing a note to the Company in the
amount of $350,000 (the "Note"). The Note is due on August 24, 2000 and bears
interest, payable annually, at 8% per annum commencing August 24, 1996. Accrued
interest on the Note as of December 31, 1996 totaling $31,582 has been forgiven.

     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:

     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.
 
11. LEASES
 
     The Company leases its present facilities in Wilmington, Massachusetts,

12. RELATED-PARTY TRANSACTIONS
 
     The Company purchases computers and other networking equipment from a
computer distributor whose principal shareholder is a director of the Company.
Purchases of equipment totaled $77,758 and $186,163 for 1996 and 1995,
respectively. As of December 31, 1996, there are no amounts payable to the
distributor.
 
     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.
 
     (b) Pro Forma Financial Information.  The acquisition of ATI has been
accounted for using the purchase method of accounting. In connection with such
acquisition, World Access recorded a charge of approximately $4.0 million,
representing the portion of the purchase price for ATI allocated to in-process
research and development. The following unaudited pro forma consolidated balance
sheet as of September 30, 1997 reflects the acquisition of ATI as if it had been
completed on September 30, 1997. The following unaudited pro forma consolidated
statement of operations for the year ended December 31, 1996 and the nine months
ended September 30, 1997 reflect the acquisition of ATI as if it had been
completed as of January 1, 1996.
 
     The pro forma data does not purport to be indicative of the results which
would actually have been reported if the acquisition had occurred on such dates
or which may be reported in the future. The pro forma data should be read in
conjunction with the historical consolidated financial statements of the
Company, the historical consolidated financial statements of ATI and the related
notes thereto.

(A)  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 research and development
     projects of ATI was expensed at the consummation of the Merger on January
     29, 1998. The amount of this one-time non-recurring charge was
     approximately $4.0 million. Since this charge was directly related to the
     acquisition and will not recur, the pro forma financial statements have
     been prepared excluding the change. The Company has not yet determined the
     final allocation of the purchase price, and accordingly, the amounts shown
     below may differ from the amounts ultimately recorded.

wholly owned subsidiary of Parent ("Merger Sub"), ADVANCED TECHCOM, INC., a
Delaware corporation ("ATI"), and ERNEST H. LIN, an individual resident of the
Commonwealth of Massachusetts (the "Signing Stockholder").
 
                                  WITNESSETH:
 
     WHEREAS, the respective Boards of Directors of Parent, Merger Sub and ATI
each have approved this Agreement and the merger (the "Merger") of ATI with and
into Merger Sub upon the terms and conditions contained herein and in accordance
with the General Corporation Law of the State of Delaware ("DGCL"); and
 
     WHEREAS, the parties desire to make certain representations, warranties and
agreements in connection with the Merger and also to set forth certain
conditions thereto.
 
     NOW, THEREFORE, in consideration of the premises and of the mutual
covenants and agreements set forth herein, the parties hereto hereby agree as

                                   ARTICLE 1.
 
                                   THE MERGER
 
     SECTION 1.1.  Surviving Corporation.  Subject to the provisions of this
Agreement and the DGCL, at the Effective Time (as hereinafter defined), ATI
shall be merged with and into Merger Sub and the separate corporate existence of
ATI shall cease. Merger Sub shall be the surviving corporation in the Merger
(hereinafter sometimes called the "Surviving Corporation") and shall continue
its corporate existence under the laws of the State of Delaware. The Merger
shall have the effect set forth in Section 259 of the DGCL, which, among other
things, shall result in the Surviving Corporation assuming the liabilities of
ATI by operation of merger.
 
     SECTION 1.2.  Certificate of Incorporation.  The Certificate of
Incorporation of Merger Sub shall be the Certificate of Incorporation of the
Surviving Corporation until thereafter duly amended in accordance with its terms
and the DGCL.
 
     SECTION 1.3.  Bylaws.  The Bylaws of Merger Sub shall be the Bylaws of the
Surviving Corporation until thereafter duly amended in accordance with their
terms and the DGCL.
 
     SECTION 1.4.  Directors.  The directors of the Surviving Corporation shall
consist of the directors of Merger Sub immediately prior to the Effective Time
and the Signing Stockholder shall be elected as a director of the Surviving
Corporation at the Effective Time, and all such directors shall hold office from
the Effective Time until their respective successors are duly elected and
qualified.
 
     SECTION 1.5.  Officers.  The officers of the Surviving Corporation shall
consist of the officers of Merger Sub immediately prior to the Effective Time,
such officers to hold office from the Effective Time until their respective
successors are duly elected and qualified.
 
     SECTION 1.6.  Effective Time.  The parties hereto shall cause a Certificate
of Merger meeting the requirements of the DGCL (the "Certificate of Merger") to
be properly executed and filed on the Closing Date (as hereinafter defined) with
the Secretary of State of the State of Delaware. The Merger shall become
effective as of the date of the filing of the properly executed Certificate of
Merger. The date and time when the Merger becomes effective is herein referred

                                   ARTICLE 2.
 
                              CONVERSION OF SHARES
 
     SECTION 2.1.  ATI Capital Stock.  As of the Effective Time, by virtue of
the Merger and without any action on the part of any holder thereof:
 
          (a) Subject to Section 2.2, (i) all of the shares of the Series A
     Convertible Preferred Stock, $.10 par value per share, of ATI ("ATI Stock")
     issued and outstanding immediately prior to the Effective Time (other than
     shares of ATI Stock held in treasury or shares of ATI Stock held by Parent)
     shall be converted into the right to receive the following (the "Merger
     Consideration"): (A) a number of shares of Parent common stock, $.01 par
     value per share (the "Parent Common Stock"), equal to (x) $10,000,000 less
     the expenses of the ATI Stockholders (as hereinafter defined) incurred in
     connection with the Merger in excess of $50,000 divided by (y) the Average
     Closing Price (as hereinafter defined) (the "Parent Shares"), which Parent
     Shares will be issued to the holders of ATI Stock (each a "Stockholder"
     and, collectively, the "Stockholders") in the manner contemplated by
     Section 2.3; and (B) a number of shares of Parent Common Stock equal to
     $5,000,000 divided by the Average Closing Price, which shares of Parent
     Common Stock will be deposited and held in escrow pursuant to Section
     2.1(b) below (the "Escrow Shares"); and (ii) all of the shares of the
     Common Stock, $.10 par value per share, of ATI (the "ATI Common Stock")
     issued and outstanding immediately prior to the Effective Time (other than
     shares of ATI Common Stock held in treasury or shares of ATI Common Stock
     held by Parent) shall be converted into the right to receive $.01 per
     share. At the Closing, each Stockholder shall be entitled to that portion
     of the aggregate Merger Consideration as it relates to the proportion of
     the aggregate liquidation preference of such Stockholder's ATI Stock
     relative to the aggregate liquidation preference of the ATI Stock, and each
     holder of ATI Common Stock (each an "ATI Common Stockholder" and,
     collectively, the "ATI Common Stockholders" and, together with the
     Stockholders, the "ATI Stockholders") shall be entitled to a cash payment
     equal to the aggregate number of shares of ATI Common Stock held by him
     multiplied by $.01. For purposes hereof, "Average Closing Price" shall mean
     the arithmetic average of the daily closing price per share, rounded to
     four decimal places, of the Parent Common Stock as reported on the Nasdaq
     National Market for each of the trading days in the period commencing on
     (and including) October 27, 1997 and ending on the trading day that occurs
     two trading days prior to (and not including) the Closing Date (as
     hereinafter defined).
 
          (b) The Escrow Shares shall be deposited with the Escrow Agent (as
     hereinafter defined) within five (5) business days of the Closing to be
     held and distributed pursuant to the terms of an Escrow Agreement by and
     between Parent, Merger Sub, the Stockholders and Cauthen & Feldman, as the
     escrow agent (the "Escrow Agent"), substantially in the form attached
     hereto as Exhibit 2.1(b) (the "Escrow Agreement").
 
          (c) Each share of common stock, par value $.01 per share, of Merger
     Sub that is issued and outstanding immediately prior to the Effective Time
     shall remain outstanding and shall be unchanged after the Merger, all of
     which shares have been issued to Parent and constitute the only outstanding
     shares of capital stock of the Surviving Corporation.
 
          (d) Each share of the ATI Stock or ATI Common Stock issued and
     outstanding immediately prior to the Effective Time that is then held in
     the treasury of ATI shall be canceled and retired and all rights in respect
     thereof shall cease to exist, without any conversion thereof or payment of
     any consideration therefor.
 
          (e) Each warrant, stock option or other right, if any, to purchase
     shares of ATI Stock or ATI Common Stock issued and outstanding immediately
     prior to the Effective Time shall be canceled (whether or not such warrant,
     option or other right is then exercisable), and the holder of each stock
     option issued under ATI's 1995 Stock Option Plan, as amended, shall be
     entitled to a cash payment from the Parent in an amount equal to the
     product of (i) $1.00 less the exercise price for the option held by such
     holder, multiplied by (ii) the maximum number of shares of ATI Common Stock
     such Holder would be entitled to receive upon exercise of such option if so
     exercised on December 31, 1997; provided,
 
                                      D-27
<PAGE>   263
 
     however, that any payment to be made to the Signing Stockholder as a result
     of this Section 2.1(e) shall be made by Parent by delivering cash in the
     amount of one-half of such payment and shares of Parent Common Stock having
     an aggregate value (valued at the Average Closing Price) equal to one-half
     of such payment.
 
     SECTION 2.2.  Fractional Shares.  No scrip or fractional shares of Parent
Common Stock shall be issued in the Merger. In lieu thereof, if a Stockholder
would otherwise have been entitled to a fractional share of Parent Common Stock
hereunder, then such Stockholder shall be entitled, after the later of (a) the
Effective Time or (b) the surrender of his certificate(s) that represent such
shares of ATI Stock, to receive from Parent an amount in cash in lieu of such
fractional share, based on a value per share of Parent Common Stock equal to the
Average Closing Price.
 
     SECTION 2.3.  Exchange of ATI Stock.
 
          (a) Exchange.  From and after the Effective Time, upon exchange of a
     certificate or certificates which immediately prior thereto represents
     outstanding shares of ATI Stock, a Stockholder shall be entitled to
     receive, upon surrender to Parent of such certificate or certificates duly
     endorsed in blank, one or more certificates as requested by such
     Stockholder (properly issued, executed and countersigned, as appropriate)
     representing that number of whole shares of Parent Common Stock to which
     such Stockholder shall have become entitled pursuant to the provisions of
     Section 2.1(a)(i)(A) and a check representing the aggregate cash
     consideration to which such Stockholder shall have become entitled as to
     any fractional share, and upon exchange of a certificate or certificates
     which immediately prior thereto represents shares of ATI Common Stock, an
     ATI Common Stockholder shall be entitled to receive, upon surrender to
     Parent of such certificate or certificates duly endorsed in blank, a check
     representing the aggregate cash consideration to which such ATI Common
     Stockholder shall have become entitled pursuant to Section 2.1(a)(ii)
     above, and all of the certificate or certificates so surrendered shall
     forthwith be canceled. No interest will be paid or accrued on the cash
     payable upon the surrender of any certificate. No portion of the
     consideration to be received pursuant to Sections 2.1 and 2.2 upon exchange
     of a certificate (whether a certificate representing shares of Parent
     Common Stock or by check representing any cash payable hereunder) may be
     issued or paid to a person other than the person in whose name the
     certificate surrendered in exchange therefor is registered. From the
     Effective Time until surrender in accordance with the provisions of this
     Section 2.3, each certificate shall represent for all purposes only the
     right to receive the consideration provided in Sections 2.1 and 2.2. All
     payments in respect of shares of ATI Stock or ATI Common Stock that are
     made in accordance with the terms hereof shall be deemed to have been made
     in full satisfaction of all rights pertaining to such securities.
 
          (b) Lost Certificates.  In the case of any lost, mislaid, stolen or
     destroyed certificate, the ATI Stockholder may be required, as a condition
     precedent to delivery to the Stockholder of the consideration described in
     Sections 2.1 and 2.2, to deliver to Parent a satisfactory indemnity
     agreement as Parent may direct as indemnity against any claim that may be
     made against Parent or the Surviving Corporation with respect to the
     certificate alleged to have been lost, mislaid, stolen or destroyed.
 
          (c) No Transfers After Effective Time.  After the Effective Time,
     there shall be no transfers on the stock transfer books of the Surviving
     Corporation of the shares of ATI Stock or ATI Common Stock that were
     outstanding immediately prior to the Effective Time. If, after the
     Effective Time, certificates representing the ATI Stock or the ATI Common
     Stock are presented to the Surviving Corporation for transfer, they shall
     be canceled and exchanged for the consideration described in Sections 2.1
     and 2.2.
 
          (d) Unclaimed Shares or Cash.  Any shares of Parent Common Stock or
     cash due former stockholders of ATI pursuant to Sections 2.1 and 2.2 hereof
     that remains unclaimed by such former stockholders for six months after the
     Effective Time shall be held by Parent, and any former holder of ATI Stock
     or ATI Common Stock who has not theretofore complied with Section 2.3 (a)
     and (b) shall thereafter look only to Parent for issuance of the number of
     shares of Parent Common Stock and other consideration to which such holder
     has become entitled pursuant to the provisions of Sections 2.1 and 2.2;
     provided, however, that neither Parent nor any party hereto shall be liable
     to a former holder of shares of

heretofore made available to Parent accurate and complete copies of its
Certificate of Incorporation and Bylaws, as currently in effect, and has made

its subsidiaries, (ii) to the best knowledge of ATI, any ATI Material Contract
(as hereinafter defined), (iii) to the best knowledge of ATI, any judgment,

<PAGE>   265
 
have a material adverse effect upon the assets, liabilities, results of

          (a) Capitalization.  The authorized capital stock of ATI consists of

     transferred, delivered or sold, additional shares of the capital stock or
     other securities of ATI or obligating ATI or any of its subsidiaries to
     grant, extend or enter into any such agreement or commitment.
 
          (b) Ownership.  The ATI Stockholders are the record and beneficial
     owners of all shares of ATI Stock or ATI Common Stock to be exchanged
     pursuant to Section 2.3 and their relative share ownership is set forth in
     the Disclosure Letter, and, at the Closing, the ATI Stockholders will own

     of capital stock or other equity interests of each such subsidiary owned by
     ATI or any of its subsidiaries are set forth in the ATI Disclosure Letter
     and are owned by ATI, either directly or indirectly, free and clear of all
     liens, claims, options, charges, encumbrances or rights of others.

     combination or reclassification of shares of capital stock declared or made
     by ATI, or (iv) any agreement to do any of the foregoing.

     have not been (i) any material losses suffered other than in the ordinary
     course of business, (ii) any material assets mortgaged, pledged or made
     subject to any lien, charge or other encumbrance, (iii) any material

     ATI's books or records, except for depreciation and amortization taken in
     the ordinary course of business and consistent with past practice, (vii)

     transactions in the ordinary course of business and consistent with past
     practice and which in any event do not exceed $10,000 in the aggregate,
     (viii) any single capital expenditure or commitment in excess of $10,000
     for additions to property or equipment, or aggregate capital expenditures
     and commitments in excess of $20,000 for additions to property or
     equipment, (ix) any material transactions entered into other than in the
     ordinary course of business, (x) any agreements to do any of the foregoing,

     have had or are reasonably likely to have a material adverse effect on the
     assets, liabilities, results of operations, financial condition or business
     of ATI and its subsidiaries taken as a whole.
 
     SECTION 3.7.  Legal Proceedings.  There are no suits, actions, claims,
proceedings or investigations pending or, to the best knowledge of ATI,
threatened against, relating to or involving ATI or any of its subsidiaries (or
any of their respective officers or directors) before any court, arbitrator or
administrative or governmental body, which, if finally determined adversely, are
reasonably likely, individually or in the aggregate, to have a material adverse
effect on the assets, liabilities, results of operations, financial condition,
business of ATI and its subsidiaries taken as a whole. All pending or threatened
suits, actions, claims, proceedings or investigations relating to or involving
ATI or any of its subsidiaries (or any of their respective officers or
directors) before any court, arbitrator or administrative or governmental body

generally accepted accounting principles. Neither ATI nor any of its
subsidiaries is subject to any judgment, decree, injunction, rule or order of
any court nor is either ATI or any of its subsidiaries subject to any
governmental restriction applicable to it, which is reasonably likely (a) to
have a material adverse effect on the assets, liabilities, results of
operations, financial condition or business of ATI and its subsidiaries taken as
a whole, or (b) to cause a material limitation on the ability of Parent to
operate the business of ATI after the Closing.
 
     SECTION 3.8.  Compliance with Law.  Each of ATI and its subsidiaries has
all material authorizations, approvals, licenses and orders of and from all
governmental and regulatory officers and bodies necessary to carry on its
business as it is currently being conducted, to own or hold under lease the
properties and assets
                                      D-31
<PAGE>   267
 
it owns or holds under lease and to perform all of its obligations under the
agreements to which it is a party, and each of ATI and its subsidiaries has been
and is in compliance with all applicable laws, regulations and administrative
orders of any country, state or municipality or of any subdivision thereof to
which its business or its employment of labor or its use or occupancy of
properties or any part thereof are subject, the failure to obtain or the
violation of which would have a material adverse effect upon its assets,
liabilities, results of operations, financial condition or business of ATI and
its subsidiaries taken as a whole.
 
     SECTION 3.9.  ATI Material Contracts.  The ATI Disclosure Letter contains a
correct and complete list of the following (hereinafter referred to as the "ATI
Material Contracts"):
 
          (a) all bonds, debentures, notes, mortgages, indentures or guarantees

     properties or assets (real, personal or mixed, tangible or intangible) is
     bound;
 
          (b) all material leases to which ATI or any of its subsidiaries is a
     party or by which any of their respective properties or assets (real,
     personal or mixed, tangible or intangible) is bound;
 
          (c) all loans and credit commitments to ATI or any of its subsidiaries
     which are outstanding, together with a brief description of such
     commitments and the name of each financial institution granting the same;
 
          (d) all contracts or agreements which limit or restrict ATI or any of
     its subsidiaries from engaging in any business in any jurisdiction or limit
     or restrict others from competing with ATI or any of its subsidiaries in
     any jurisdiction;
 
          (e) all agreements and documentation evidencing currently outstanding
     loans or advances made by ATI or any of its subsidiaries to or on behalf of
     its customers; and
 
          (f) all existing contracts and commitments (other than those described
     in subparagraphs (a), (b), (c), (d) or (e) of this Section 3.9, the ATI
     Customer Contracts (as hereinafter defined)), and the ATI Benefit Plans (as
     hereinafter defined) to which ATI or any of its subsidiaries is a party or
     by which their respective properties or assets may be bound involving an
     annual commitment or annual payment by any party thereto of more than
     $25,000 individually, or which have a fixed term extending more than twelve
     (12) months from the date hereof and which involve a total commitment or
     payment by any party thereto of more than $50,000.
 
To the best knowledge of ATI, true and complete copies of all ATI Material
Contracts, including all amendments thereto, have been made available to Parent.
The ATI Material Contracts are valid and enforceable in accordance with their
respective terms with respect to ATI and valid and enforceable in accordance
with their respective terms with respect to any other party thereto, in each
case to the extent material to the business and operations of ATI, and subject
to applicable bankruptcy, insolvency and other similar laws affecting the
enforceability of creditors' rights generally, general equitable principles and
the discretion of courts in granting equitable remedies. Except for events or
occurrences, the consequences of which, individually or in the aggregate, would
not have a material adverse effect on the assets, liabilities, results of
operations, financial condition or business of ATI and its subsidiaries taken as
a whole, there is not under any of the ATI Material Contracts any existing
breach, default or event of default by ATI or event that with notice or lapse of
time or both would constitute a breach, default or event of default by ATI, nor
does ATI know of, and ATI has not received notice of, or made a claim with
respect to, any breach or default by any other party thereto.
 
     SECTION 3.10.  ATI Customer Contract.  The ATI Disclosure Letter sets forth
a true and complete list of all agreements or contracts pursuant to which ATI or
any of its subsidiaries provides goods or services to their respective customers
(the "ATI Customer Contracts"). Neither ATI nor any of its subsidiaries provides
goods or services to their respective customers pursuant to verbal or oral
agreements or contracts. The ATI Disclosure Letter sets forth a true and
complete list of all customers of ATI which the management of ATI reasonably
believes in good faith may terminate their contracts with ATI or may assert a
claim for damages against ATI as a result of a default by ATI of its obligations
under such contract or for any other reason, other
 
                                      D-32
<PAGE>   268
 
than customer terminations arising in the ordinary course of business consistent
with past practices and which do not in any event in the aggregate involve
annual revenues of $50,000 or more. The execution, delivery and performance of
this Agreement by ATI and the Signing Stockholder and the consummation of the
transactions contemplated hereby by ATI and the Signing Stockholder will not,
with the passing of time or giving of notice or both, violate or conflict with
or constitute a default under or give rise to a termination right under any ATI
Customer Contract except such violations, conflicts and defaults which in the
aggregate would not have a material adverse effect on the assets, liabilities,
results of operations, financial condition or business of ATI and its
subsidiaries taken as a whole.
 
     SECTION 3.11.  Tax Returns; Taxes.  Each of ATI and its subsidiaries has
duly filed all federal, state, local and foreign tax returns required to be
filed by it and has duly paid or made adequate provision for the payment of all
taxes which are due and payable pursuant to such returns or pursuant to any
assessment with respect to taxes in such jurisdictions, whether or not in
connection with such returns, except for incidental interest and penalties which
may be due and payable, but which are not material in amount. The liability for
taxes reflected in the 1997 Balance Sheet is sufficient for the payment of all
unpaid taxes, whether or not disputed, that are accrued or applicable for the
period ended November 30, 1997, and for all years and periods ended prior
thereto. All deficiencies asserted as a result of any examinations by the
Internal Revenue Service ("IRS") or any other taxing authority have been paid,
fully settled or adequately provided for in the 1997 Balance Sheet. There are no
pending claims asserted for taxes of ATI or any of its subsidiaries or
outstanding agreements or waivers extending the statutory period of limitation
applicable to any tax return of ATI or any of its subsidiaries for any period.
Each of ATI and its subsidiaries has made all estimated income tax deposits and
all other required tax payments or deposits and has complied for all prior
periods in all material respects with the tax withholding provisions of all
applicable federal, state, local, foreign and other laws. ATI has made available
to Parent true, complete and correct copies of federal income tax returns of ATI
and its subsidiaries for the last three (3) taxable years and made available
such other tax returns requested by Parent.
 
     SECTION 3.12.  Officers, Directors, and Employees.  The ATI Disclosure

ATI and each of its subsidiaries, specifying their office and annual rate of

     forth the terms of the ATI Benefit Plan, or if there are no such documents
     evidencing the ATI Benefit Plan, a full description of the ATI Benefit
     Plan; (ii) the ERISA summary plan description and any other summary of plan
     provisions provided to participants or beneficiaries for each such ATI
     Benefit Plan; (iii) the annual reports filed for the most recent three (3)
     plan years and most recent financial statements or periodic accounting of
     related plan assets with respect to each ATI Benefit Plan; (iv) the most
     recent favorable determination letter, opinion or ruling from the IRS for
     each ATI Benefit Plan, the assets of which are held in trust, to the effect
     that such trust is exempt from federal income tax; and (v) each opinion or
     ruling from the Department of Labor or the Pension Benefit Guaranty
     Corporation ("PBGC") with respect to such ATI Benefit Plans.
 
          (f) Qualified Status.  Except as described in the ATI Disclosure
     Letter, each ATI Benefit Plan that is funded through a trust or insurance
     contract has at all times satisfied in all respects, by its terms and in
     its operation, all applicable requirements for an exemption from federal
     income taxation under Section 501(a) of the Code. Neither ATI nor any ATI
     ERISA Affiliate maintains an ATI Benefit Plan which meets the requirements
     of Section 401(a) of the Code (each a "401 Plan"). Any determination letter
     issued by the IRS to the effect that any such 401 Plan qualifies under
     Section 401(a) of the Code and that the related trust is exempt from
     taxation under Section 501(a) of the Code remains in effect and has not
     been revoked. Each such 401 Plan, if any, currently complies in form with
     the requirements under Section 401(a) of the Code, other than changes
     required by statutes, regulations and rulings for which amendments are not
     yet required. Each such 401 Plan, if any, has been administered according
     to its terms (except for those terms which are inconsistent with the
     changes required by statutes, regulations and ruling for which changes are
     not yet required to be made, in which case any such 401 Plan has been
     administered in accordance with the provisions of those statutes,
     regulations and rulings) and in accordance with the requirements of Section
     401(a) of the Code. Each such 401 Plan, if any, has been tested for
     compliance with, and has satisfied the requirements of, Section 401(k)(3)
     and 401(m)(2) of the Code for each plan year ending prior to the Effective
     Date.
 
          (g) Compliance.  Except as described in the ATI Disclosure Letter,
     each ATI Benefit Plan maintained by ATI or an ATI ERISA Affiliate has at
     all times been maintained, by its terms and in operation, in accordance
     with all applicable laws in all material respects, including (to the extent
     applicable) Code Section 4980B. There has been no failure to comply with
     applicable ERISA or other
 
                                      D-34
<PAGE>   270
 
     requirements concerning the filing of reports, documents and notices with
     the Secretary of Labor and Secretary of Treasury or the furnishing of such
     documents to participants or beneficiaries that could subject any ATI
     Benefit Plan, ATI, any ATI ERISA Affiliate, Parent or any of its affiliates
     to any material civil or any criminal sanction.
 
          (h) Legal Actions.  There are no actions, audits, suits or claims
     known to the Signing Stockholder which are pending or threatened against
     any ATI Benefit Plan, any fiduciary of any of ATI Benefit Plans with
     respect to the ATI Benefit Plans or against the assets of any of the ATI
     Benefit Plans, except claims for benefits made in the ordinary course of
     the operation of such plans.
 
          (i) Funding.  ATI and each ATI ERISA Affiliate has made full and
     timely payment of all amounts required to be contributed under the terms of
     each ATI Benefit Plan and applicable law or required to be paid as expenses
     under such ATI Benefit Plan, and no excise taxes are assessable as a result
     of any nondeductible or other contributions made or not made to an ATI
     Benefit Plan. No event or condition exists with respect to any ATI Benefit
     Plan subject to Title IV of ERISA which could be deemed a "Reportable
     Event" (as defined in Title IV of ERISA) with respect to which the thirty
     (30) day notice requirement has not been waived which could result in a
     material liability to ATI, and no condition exists which would subject ATI
     to a material fine under Section 4071 of ERISA. The assets of all ATI
     Benefit Plans which are required under applicable laws to be held in trust
     are in fact held in trust, and the assets of each such ATI Benefit Plan
     equal or exceed the liabilities of each such plan. The liabilities of each
     other plan are properly and accurately reported on the financial statements
     and records of ATI. The assets of each ATI Benefit Plan are reported at
     their fair market value on the books and records of each plan.
 
          (j) Liabilities.  Neither ATI nor any ATI ERISA Affiliate is subject
     to any material liability, tax or penalty whatsoever to any person
     whomsoever as a result of ATI's or any ATI ERISA Affiliate's engaging in a
     prohibited transaction under ERISA or the Code, and the Stockholder has no
     knowledge of any circumstances which reasonably might result in any such
     material liability, tax or penalty as a result of a breach of fiduciary
     duty under ERISA. The termination of or withdrawal from any ATI Benefit
     Plan maintained by ATI or an ATI ERISA Affiliate which is subject to Title
     IV of ERISA or any other ATI Benefit Plan immediately after the Effective
     Time will not subject Parent, the Surviving Corporation, Merger Sub or any
     ATI ERISA Affiliate to any additional contribution requirement or to any
     other liability, tax or penalty whatsoever (excluding any liability, tax or
     penalty attributable solely to the fact that such termination or withdrawal
     would violate the permanency requirement of Section 401 (a) of the Code or
     an excise tax under Code Section 4980). Neither the execution nor the
     performance of the transactions contemplated by this Agreement will create,
     accelerate or increase any obligations under any ATI Benefit Plan. Neither
     ATI nor any ATI ERISA Affiliate has any obligation to any retired or former
     employee, or any current employee upon retirement, under any ATI Benefit
     Plan.
 
          (k) Amendment/New Plans.  From the date of this Agreement to the
     Effective Time, no amendment shall be made to any ATI Benefit Plan, no
     commitment shall be made to amend any ATI Benefit Plan and no commitment
     shall be made to continue any ATI Benefit Plan or to adopt any new ATI
     Benefit Plan for the benefit of any employees of ATI or any ATI ERISA
     Affiliate absent the express written consent of Parent.
 
          (l) Excess Parachute Payments.  No payment required to be made to any
     employee associated with ATI as a result of the transactions contemplated
     hereby under any contract or otherwise will, if made, constitute an "excess
     parachute payment" within the meaning of Section 280G of the Code or be
     nondeductible under Section 162(m) of the Code.
 
          (m) No Acceleration of Liability Under Benefit Plans.  The
     consummation of the transactions contemplated hereby will not accelerate or
     increase any liability under any ATI Benefit Plan because of an
     acceleration or increase of any of the rights or benefits to which
     employees of ATI or any ATI ERISA Affiliate may be entitled thereunder.
 
                                      D-35
<PAGE>   271
 
          (n) Statutory Benefits.  Except as described in the ATI Disclosure
     Letter, ATI has, on a timely basis, made all payments, withholdings and
     filings of any kind required of it by, and has otherwise complied in all
     material respects with, any applicable law, regulation or administrative
     order concerning pension, health, welfare, unemployment, workers'
     compensation or similar benefits administered by any governmental,
     regulatory or public body.
 
     SECTION 3.14.  Labor Relations.  To the best knowledge of ATI, each of ATI
and its subsidiaries is in compliance in all material respects with all federal,
state and foreign laws respecting employment and employment practices, terms and
conditions of employment, wages and hours, and is not engaged in any unfair
labor or unlawful employment practice. There is no unlawful employment practice
discrimination charge involving ATI pending before the Equal Employment
Opportunity Commission ("EEOC"), EEOC-recognized state "referral agency" or any
other governmental agency. There is no unfair labor practice charge or complaint
against ATI or any of its subsidiaries pending before the National Labor
Relations Board ("NLRB"). There is no labor strike, dispute, slowdown or
stoppage actually pending or, to the best knowledge of ATI, threatened against
or involving or affecting ATI or any of its subsidiaries, and no NLRB
representation question exists respecting any of its employees. No grievance or
arbitration proceeding is pending against ATI and no written claim therefor
exists. There is no collective bargaining agreement that is binding on ATI or
any of its subsidiaries.
 
     SECTION 3.15.  Insurance.  ATI has heretofore provided to Parent a true and
complete list of its current insurance coverages for ATI and its subsidiaries,
including names of carriers, amounts of coverage and premiums therefor. Each of
ATI and its subsidiaries has been and is insured with respect to its properties
and the conduct of its business in such amounts and against such risks as are
reasonable in relation to its business and will use its reasonable efforts to
maintain such insurance at least through the Effective Time. ATI has made
available to Parent true and complete copies of all insurance policies covering
ATI and its subsidiaries, its properties, assets, employees and/or operations.
 
     SECTION 3.16.  Title to Properties and Related Matters.  Each of ATI and
its subsidiaries has good and valid title to or valid leasehold interests in its
properties reflected in the 1997 Balance Sheet or acquired after the date
thereof (other than properties sold or otherwise disposed of in the ordinary
course of business), and all of such properties are held free and clear of all
title defects, liens, encumbrances and restrictions, except, with respect to all
such properties, (a) mortgages and liens securing debt reflected as liabilities
on the 1997 Balance Sheet and (b)(i) liens for current taxes and assessments not
in default, (ii) mechanics', carriers', workmen's, materialmen's, repairmen's,
statutory or common law liens either not delinquent or being contested in good
faith, and (iii) encumbrances, covenants, rights of way, building or use
restrictions, easements, exceptions, variances, reservations and other similar
matters or limitations, if any, which do not have a material adverse effect on
ATI's use of the property affected. Notwithstanding the immediately preceding
sentence, ATI makes no representation or warranty in this Section 3.16 or
otherwise regarding the validity of title to any such properties in which ATI
has only a leasehold interest.
 
     SECTION 3.17.  Environmental Matters.  Neither ATI nor any of its
subsidiaries owns, nor has at any time owned, any real property. To the best
knowledge of ATI, there has been no material release of a hazardous substance,
as that term is defined in the Comprehensive Environmental Response,
Compensation and Liability Act of 1980, 42 U.S.C. ss. 9601(14), or any petroleum
product by ATI or any of its subsidiaries into the environment at any property
ever owned, leased or used by ATI or any of its subsidiaries (the "Premises"),
including, without limitation, any such release in the soil or groundwater
underlying the Premises and, to the best knowledge of ATI, there has been no
such release by any other party at any of the Premises. To the best knowledge of
ATI, neither ATI nor any of its subsidiaries has disposed of any hazardous
substances (as defined below). ATI has not received notice of any violation of
any Environmental Law (as defined below) nor has it been advised of any claim or
liability pursuant to any Environmental Law brought by any domestic or foreign
governmental agency or private party. There are no Environmental Liabilities (as
defined below) of ATI that, individually or in the aggregate, have had or would
reasonably be expected to have a material adverse effect on the assets,
liabilities, results of operations, financial condition or business of ATI and
its subsidiaries taken as a whole. As used in this Agreement, "Environmental
Laws" means any and all federal, state, local and foreign statutes, laws,
judicial decisions, regulations, ordinances, rules, judgments,
                                      D-36
<PAGE>   272
 
orders, decrees, codes, plans, injunctions, permits, concessions, grants,
franchises, licenses, agreements and governmental restrictions, whether now or
hereafter in effect, relating to human health, the environment or to emissions,
discharges or releases of pollutants, contaminants, Hazardous Substances or
wastes into the environment, including without limitation ambient air, surface
water, ground water or land, or otherwise relating to the manufacture,
processing, distribution, use, treatment, storage, disposal, transport or
handling of pollutants, contaminants, Hazardous Substances or wastes or the
clean-up or other remediation thereof. "Environmental Liabilities" with respect
to any person means any and all liabilities of or relating to such person or any
of its subsidiaries (including any entity which is, in whole or in part, a
predecessor of such Person or any of its subsidiaries), whether vested or
unvested, contingent or fixed, actual or potential, known or unknown, which (i)
arise under or relate to matters covered by Environmental Laws and (ii) relate
to actions occurring or conditions existing on or prior to the Closing Date.
"Hazardous Substances" means any toxic, radioactive, caustic or otherwise
hazardous substance, including petroleum, its derivatives, by-products and other
hydrocarbons, or any substance having any constituent elements displaying any of
the foregoing characteristics, including, without limitation, any substance
regulated under Environmental Laws.
 
     SECTION 3.18.  Patents, Trademarks, Trade Names.  The ATI Disclosure Letter
sets forth a true and complete list of: (a) all material patents, trademarks and
trade names (including all federal, state and foreign registrations pertaining
thereto) and all material copyright registrations owned by ATI or any of its
subsidiaries (collectively, the "Proprietary Intellectual Property"); and (b)
all patents, trademarks, trade names, copyrights and all technology and
processes used by ATI in its business which are material to its business and are
used pursuant to a license or other right granted by a third party
(collectively, the "Licensed Intellectual Property" and, together with the
Proprietary Intellectual Property, herein referred to as "Intellectual
Property"). A true and complete list of all such licenses with respect to
Licensed Intellectual Property is set forth in the ATI Disclosure Letter. Each
of the federal, state and foreign registrations pertaining to the Proprietary
Intellectual Property is valid and in full force and effect. All required
filings in association with such registrations have been properly made and all
required fees have been paid. ATI owns, or has the right to use pursuant to
valid and effective agreements, all Intellectual Property, and the consummation
of the transactions contemplated hereby will not alter or impair any such
rights, except for such defects in title or other matters which in the aggregate
would not have a material adverse effect on the assets, liabilities, results of
operations, financial condition or business of ATI and its subsidiaries taken as
a whole. No claims are pending against ATI by any person with respect to the use
of any Intellectual Property or challenging or questioning the validity or
effectiveness of any license or agreement relating to the same, and, to the best
knowledge of ATI, the current use by ATI or any of its subsidiaries of the
Intellectual Property does not infringe on the rights of any third party. The
ATI Disclosure Letter sets forth a list of all jurisdictions in which ATI is
operating under a trade name, and each jurisdiction in which any such trade name
is registered.
 
     SECTION 3.19.  Transactions with Affiliates.  No stockholder or director of
ATI, or any person with whom any such stockholder or director has any direct or
indirect relation by blood, marriage or adoption, or any entity in which any
such person owns any beneficial interest (other than a publicly held corporation
whose stock is traded on a national securities exchange or in the
over-the-counter market and less than 1% of the stock of which is beneficially
owned by all such persons) has any interest in (i) any contract, arrangement or
understanding with, or relating to, the business or operations of ATI or any of
its subsidiaries, (ii) any loan, arrangement, understanding, agreement or
contract for or relating to indebtedness of ATI or any of its subsidiaries, or
(iii) any property (real, personal or mixed, tangible or intangible) used, or
currently intended to be used, in the business or operations of ATI.
 
     SECTION 3.20.  Brokers, Finders, and Investment Bankers.  Neither ATI nor
any of its officers, directors or employees has employed any broker, finder or
investment banker or incurred any liability for any investment banking fees,
financial advisory fees, brokerage fees or finders' fees in connection with the
transactions contemplated herein.

                                   ARTICLE 4.
 
                    REPRESENTATIONS AND WARRANTIES OF PARENT
 
     With such exceptions, if any, as may be set forth in a letter (the "Parent
Disclosure Letter") to be delivered by Parent to ATI on or before December 31,
1997 Parent hereby represents and warrants to ATI as follows:
 
     SECTION 4.1.  Organization.  Each of Parent and Merger Sub is a corporation
duly organized, validly existing and in good standing under the laws of the
jurisdiction of its incorporation and has all requisite corporate power and
authority to own, lease and operate its properties and to carry on its business
as now being conducted. Each of Parent and Merger Sub is duly qualified to
transact business, and is in good standing, as a foreign corporation in each
jurisdiction where the character of its activities requires such qualification,
except where the failure to so qualify would not have a material adverse effect
on the assets, liabilities, results of operations, financial condition or
business of Parent and its subsidiaries taken as a whole.
 
     SECTION 4.2.  Authorization.  Each of Parent and Merger Sub has full
corporate power and authority to execute and deliver this Agreement and to
perform its obligations under this Agreement and to consummate the Merger and
the other transactions contemplated hereby. The execution and delivery of this
Agreement by Parent and Merger Sub, subject only to the performance by Parent
and Merger Sub of their respective obligations hereunder and the consummation of
the Merger and the other transactions provided for herein, have been duly and
validly authorized by all necessary corporate action on the part of each of
Parent and Merger Sub. The Boards of Directors of each of Parent and Merger Sub
have approved the execution, delivery and performance of this Agreement and the
consummation of the Merger and the other transactions provided for herein. This
Agreement has been duly executed and delivered by each of Parent and Merger Sub
and constitutes the valid and binding agreement of Parent and Merger Sub,
enforceable against each of Parent and Merger Sub in accordance with its terms,
subject to applicable bankruptcy, insolvency and other similar laws affecting
the enforceability of creditors' rights generally, general equitable principles
and the discretion of courts in granting equitable remedies.
 
     SECTION 4.3.  Absence of Restrictions and Conflicts.  The execution,
delivery and performance of this Agreement, the consummation of the Merger and
the other transactions contemplated by this Agreement, and the fulfillment of
and compliance with the terms and conditions of this Agreement do not and will
not, with the passing of time or the giving of notice or both, violate or
conflict with, constitute a breach of or default under, result in the loss of
any material benefit under, or permit the acceleration of any obligation under,
(i) any term or provision of the Certificate of Incorporation or Bylaws of
Parent or Merger Sub, (ii) any contract material to the business and operations
of Parent or Merger Sub, (iii) any judgment, decree or order of any court or
governmental authority or agency to which Parent or Merger Sub is a party or by
which Parent or Merger Sub or any of their respective properties is bound, or
(iv) any statute, law, regulation or rule applicable to Parent or Merger Sub, so
as to have, in the case of subsections (ii) through (iv) above, a material
adverse effect on the assets, liabilities, results of operations, financial
condition or business of Parent and its subsidiaries taken as a whole. Except
for filing and recordation of the Certificate of Merger, no consent, approval,
order or authorization of, or registration, declaration or filing with, any
government agency or public or regulatory unit, agency, body or authority with
respect to Parent or Merger Sub is required in connection with the execution,
delivery or performance of this Agreement by Parent or Merger Sub or the
consummation of the transactions contemplated by this Agreement by Parent or
Merger Sub, the failure to obtain which would have a material adverse effect
upon the assets, liabilities, results of operations, financial condition,
business of ATI and its subsidiaries taken as a whole of Parent.
 
     SECTION 4.4.  Capitalization of Parent and Ownership of Merger Sub.  The
authorized capital stock of Parent consists of 40,000,000 shares of common
stock, $.01 par value per share, of which 19,289,077 shares were issued and
outstanding as of December 22, 1997, and 10,000,000 shares of preferred stock,
$.01 par value per share, of which no shares were issued and outstanding as of
December 1, 1997. All shares of Parent Common Stock outstanding as of the date
hereof are duly authorized, validly issued, fully paid, nonassessable and free
of preemptive rights. The shares of Parent Common Stock to be issued in the
Merger will be validly
 
                                      D-38
<PAGE>   274
 
issued, fully paid, nonassessable and free of preemptive rights. All of the
outstanding capital stock of Merger Sub is held by Parent.
 
     SECTION 4.5.  Financial Statements.  Parent has made available to ATI the
audited consolidated balance sheets of Parent and its subsidiaries as of
December 31, 1994, 1995 and 1996, and the related consolidated statements of
operations, stockholders' equity and cash flows for the fiscal years then ended,
including the notes thereto, and the unaudited consolidated balance sheet of
Parent and its subsidiaries as of September 30, 1997 and the related
consolidated statements of operations for the nine months then ended. All of the
foregoing financial statements are hereinafter collectively referred to as the
"Parent Financial Statements" and the balance sheet as of September 30, 1997 is
hereinafter referred to as the "1997 Parent Balance Sheet." The Parent Financial
Statements have been prepared from, and are in accordance with, the books and
records of Parent and present fairly the financial position and results of
operations of Parent as of the dates and for the periods indicated, in each
case, in conformity with generally accepted accounting principles, consistently
applied. As of the Closing Date, Parent shall have no liability or obligation of
any nature whatsoever, whether accrued, absolute, contingent or otherwise, other
than (x) current liabilities and obligations which are recurring in nature and
not overdue on their terms, (y) liabilities and obligations reflected and
adequately provided for on the 1997 Parent Balance Sheet and (z) liabilities and
obligations arising in the ordinary course of business of Parent, or in
connection with the transactions contemplated hereby, since the date of the 1997
Parent Balance Sheet.
 
     SECTION 4.6.  Absence of Certain Changes.
 
          (a) Certain Financial Matters; Property; Dividends.  Since the date of
     the 1997 Parent Balance Sheet, there has not been (i) any material adverse
     change in the assets, liabilities, results of operations, financial
     condition or business of Parent and its subsidiaries taken as a whole, (ii)
     any damage, destruction, loss or casualty to property or assets of Parent,
     whether or not covered by insurance, which property or assets are material
     to its operations or business, (iii) any declaration, setting aside or
     payment of any dividend or distribution (whether in cash, stock or
     property) in respect of the capital stock of Parent, or any redemption or
     other acquisition by Parent of any of the capital stock of Parent or any
     split, combination or reclassification of shares of capital stock declared
     or made by Parent, or (iv) any agreement to do any of the foregoing.
 
          (b) Other Changes.  Since the date of the 1997 Parent Balance Sheet,
     there have not been (i) any losses suffered, (ii) any material assets
     mortgaged, pledged or made subject to any lien, charge or other
     encumbrance, (iii) any material liability or obligation (absolute, accrued
     or contingent) incurred or any material bad debt, contingency or other
     reserve increase suffered, except, in each such case, in the ordinary
     course of business and consistent with past practice, (iv) any material
     claims, liabilities or obligations (absolute, accrued or contingent) paid,
     discharged or satisfied, other than the payment, discharge or satisfaction,
     in the ordinary course of business and consistent with past practice, of
     claims, liabilities and obligations reflected or reserved against in the
     Parent Financial Statements or incurred in the ordinary course of business
     and consistent with past practice since the date of the Parent Financial
     Statements, (v) any material guarantees, checks, notes or accounts
     receivable written off as uncollectible, except write-offs in the ordinary
     course of business and consistent with past practice, (vi) any write down
     of the value of any asset or investment on Parent's books or records,
     except for depreciation and amortization taken in the ordinary course of
     business and consistent with past practice, (vii) any cancellation of any
     material debts or waiver of any material claims or rights of substantial
     value, or sale, transfer or other disposition of any material properties or
     assets (real, personal or mixed, tangible or intangible) of substantial
     value, except, in each such case, in transactions in the ordinary course of
     business and consistent with past practice, (viii) any material
     transactions entered into other than in the ordinary course of business,
     (ix) any agreements to do any of the foregoing, or (x) any other events,
     developments or conditions of any character that have had or are reasonably
     likely to have a material adverse effect on the assets, liabilities,
     results of operations, financial condition or business of Parent and its
     subsidiaries taken as a whole.
 
                                      D-39
<PAGE>   275
 
     SECTION 4.7.  Legal Proceedings.  There are no suits, actions, claims,
proceedings or investigations pending or, to the best knowledge of Parent,
threatened against, relating to or involving Parent (or any of its officers or
directors) before any court, arbitrator or administrative or governmental body,
which, if finally determined adversely, are reasonably likely, individually or
in the aggregate, to have a material adverse effect on the assets, liabilities,
results of operations, financial condition or business of Parent and its
subsidiaries taken as a whole. All pending or threatened suits, actions, claims,
proceedings or investigations relating to or involving Parent (or any of its
officers or directors) before any court, arbitrator or administrative or
governmental body are adequately provided for in the 1997 Parent Balance Sheet
in accordance with generally accepted accounting principles. Parent is not
subject to any judgment, decree, injunction, rule or order of any court nor is
Parent subject to any governmental restriction applicable to it, which is
reasonably likely to have a material adverse effect on the assets, liabilities,
results of operations, financial condition or business of Parent and its
subsidiaries taken as a whole.
 
     SECTION 4.8.  Compliance with Law.  Parent has all material authorizations,
approvals, licenses and orders of and from all governmental and regulatory
officers and bodies necessary to carry on its business as it is currently being
conducted, to own or hold under lease the properties and assets it owns or holds
under lease and to perform all of its obligations under the agreements to which
it is a party, and Parent has been and is in compliance with all applicable
laws, regulations and administrative orders of any country, state or
municipality or of any subdivision thereof to which its business or its
employment of labor or its use or occupancy of properties or any part thereof
are subject, the failure to obtain or the violation of which would have a
material adverse effect upon its assets, liabilities, results of operations,
financial condition or business of Parent and its subsidiaries taken as a whole.
 
     SECTION 4.9.  Tax Returns; Taxes.  Parent has duly filed all federal,
state, local and foreign tax returns required to be filed by it and has duly
paid or made adequate provision for the payment of all taxes which are due and
payable pursuant to such returns or pursuant to any assessment with respect to
taxes in such jurisdictions, whether or not in connection with such returns. The
liability for taxes reflected in the 1997 Parent Balance Sheet is sufficient for
the payment of all unpaid taxes, whether or not disputed, that are accrued or
applicable for the period ended September 30, 1997, and for all years and
periods ended prior thereto. All deficiencies asserted as a result of any
examinations by the IRS or any other taxing authority have been paid, fully
settled or adequately provided for in the 1997 Parent Balance Sheet. There are
no pending claims asserted for taxes of Parent or outstanding agreements or
waivers extending the statutory period of limitation applicable to any tax
return of Parent for any period. Parent has made all estimated income tax
deposits and all other required tax payments or deposits and has complied for
all prior periods in all material respects with the tax withholding provisions
of all applicable federal, state, local, foreign and other laws.

ATI Parent's Annual Reports on Form 10-K for the years ended December 31, 1994,
1995 and 1996 (the "Parent SEC Reports"). As of their respective dates, the
Parent SEC Reports did not contain any untrue statement of a material fact or
omit to state any material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading. Since January 1, 1994, Parent has filed all forms, reports
and documents with the Securities and Exchange Commission required to be filed
by it pursuant to the Securities Act of 1933, as amended (the "Securities Act"),
and the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and
the rules and regulations promulgated thereunder, each of which complied as to
form, at the time such form, document or report was filed, in all material
respects with the applicable requirements of the Securities Act and the Exchange
Act and the applicable rules and regulations promulgated thereunder.
 
     SECTION 4.11.  Transactions with Affiliates.  Except as disclosed in the
Parent SEC Reports, no executive officer or director of Parent, or any person
with whom any such executive officer or director has any direct or indirect
relation by blood, marriage or adoption, or any entity in which any such person
owns any beneficial interest (other than a publicly held corporation whose stock
is traded on a national securities exchange or in the over-the-counter market
and less than 1% of the stock of which is beneficially owned by all such
persons) has any interest in (i) any contract, arrangement or understanding
with, or relating to, the business or operations of Parent, (ii) any loan,
arrangement, understanding, agreement or contract for or
                                      D-40

relating to indebtedness of Parent, or (iii) any property (real, personal or
mixed, tangible or intangible) used, or currently intended to be used, in the
business or operations of Parent.

          (ix) Perform in all material respects all of its obligations under all
     ATI Material Contracts (except those being contested in good faith) and not

     returns, reports, filings and amendments at ATI's offices prior to the
     filing thereof, which review shall not interfere with the timely filing of
     such returns.
 
     In connection with the continued operation of ATI's business between the
date of this Agreement and the Effective Time, ATI shall confer in good faith on
a regular and frequent basis with one or more representatives of Parent
designated in writing to report on operational matters of materiality and the
general status of ongoing operations. ATI acknowledges that Parent does not and
will not waive any rights it may have under this Agreement as a result of such
consultations.
 
     SECTION 5.2.  Inspection and Access to Information; Confidentiality.
 
          (a) Inspection and Access.  Between the date of this Agreement and the
     Effective Time, ATI will provide Parent and its accountants, investment
     bankers, counsel and other authorized representatives full access, during
     reasonable business hours and under reasonable circumstances to any and all
     of its premises, properties, contracts, commitments, books, records and
     other information (including tax returns filed and those in preparation)
     and will cause its respective officers to furnish to the other party and
     its authorized representatives any and all financial, technical and
     operating data and other information pertaining to its business, as each
     other party shall from time to time reasonably request.
 
          (b) Confidentiality.  Parent shall, and shall use its best efforts to
     cause its authorized representatives to, hold in strict confidence, and not
     disclose to any person without the prior written consent of ATI, or use in
     any manner except in connection with the transactions contemplated hereby,
     all information obtained from ATI in connection with the transactions
     completed hereby, except that such information may be disclosed (i) where
     necessary to any regulatory authorities or governmental agencies, (ii) if
     required by court order or decree, (iii) if it is ascertainable or obtained
     from public or published information, (iv) if it is or becomes known to the
     public other than through disclosure by such party, (v) if the recipient
     can demonstrate it was in its possession prior to disclosure thereof in
     connection with the Agreement, (vi) if the recipient can demonstrate it was
     independently developed by it, or (vii) if the disclosing party is advised
     in writing by counsel that it is legally required to make such disclosure.
 
     SECTION 5.3.  No Solicitation; Acquisition Proposals.
 
          (a) No Solicitation.  From the date hereof until the Effective Time or
     until this Agreement is terminated or abandoned as provided in Article 8,
     ATI shall not, nor shall it authorize or permit any officer, director or
     employee of, or any attorney or other advisor or representative of ATI to,
     (i) solicit or initiate, or encourage the submission of, any Acquisition
     Proposal (as hereinafter defined) or (ii) participate in any discussions or
     negotiations regarding, or furnish to any person any information with
     respect to, or take any other action to facilitate any inquiries or the
     making of any proposal that constitutes, or may reasonably be expected to
     lead to, any Acquisition Proposal. For purposes hereof, "Acquisition
     Proposal" means an inquiry, proposal or acquisition or purchase of a
     substantial amount of assets of ATI (other than investors in the ordinary
     course of business) or of over 10% of any class of equity securities of
     ATI, or any merger, consolidation, business combination, sale of
     substantially all
                                      D-42
<PAGE>   278
 
     assets, recapitalization, liquidation, dissolution or similar transaction
     involving ATI other than the transactions contemplated hereby, or any other
     transaction the consummation of which would reasonably be expected to
     impede, interfere with, prevent or materially delay the Merger or which
     would reasonably be expected to dilute materially the benefits to Parent of
     the Merger. ATI will notify Parent promptly in writing if ATI becomes aware
     that any inquiries or proposals are received by, any information is
     requested from, or any negotiations or discussions are sought to be
     initiated with ATI with respect to an Acquisition Proposal. ATI shall
     immediately cease any existing activities, discussions or negotiations with
     any third parties which may have been conducted on or prior to the date
     hereof with respect to an Acquisition Proposal and shall direct and use
     reasonable efforts to cause its officers, advisors and representatives not
     to engage in any such activities, discussions or negotiations.
 
          (b) Action by Board.  Except as set forth herein and subject to its
     fiduciary duties, the Board of Directors of ATI shall not (i) approve or
     recommend, or propose to approve or recommend, any Acquisition Proposal or
     (ii) enter into any type of agreement or letter of intent with respect to
     any Acquisition Proposal.
 
          (c) Liquidated Damages.  If, (i) prior to the termination of this
     Agreement, ATI proposes to enter into an agreement or letter of intent with
     respect to any Acquisition Proposal, it shall concurrently with entering
     into such agreement or letter of intent pay, or cause to be paid, in same
     day funds to Parent up to $100,000 of the costs and expenses incurred by
     Parent in connection with the Merger, including fees and expenses of its
     accountants and counsel (the "Expenses"), plus the sum of $250,000 (the
     "Termination Fee"), or (ii) an Acquisition Proposal shall have been made
     prior to the termination of this Agreement and within one year of such
     termination ATI enters into an agreement or letter of intent with respect
     to, or approves or recommends or takes any action to facilitate such
     Acquisition Proposal, ATI shall pay, or cause to be paid to Parent, in same
     day funds upon demand, the Expenses and the Termination Fee, provided that,
     so long as ATI is not then in breach of any of its obligations herein, no
     payment shall be due to Parent under subpart (ii) above if, at the time of
     the termination of this Agreement, ATI shall desire in good faith to
     proceed with the Merger, and Parent shall elect not to do so. The parties
     acknowledge that damages in the event of a breach of this Section 5.3 will
     be difficult to ascertain, and that the Expenses and the Termination Fee
     are intended to be full liquidated damages and such damages represent the
     parties' best estimate of their damages. The parties expressly acknowledge
     that the foregoing liquidated damages are intended not as a penalty, but as
     full liquidated damages, in the event of a breach of this Section 5, and
     Parent acknowledges the Expenses and the Termination Fee are its sole and
     exclusive remedy for a breach of this Section 5.3.
 
     SECTION 5.4.  Reasonable Efforts; Further Assurances; Cooperation.  Subject
to the other provisions of this Agreement, the parties hereto shall each use
their reasonable, good faith efforts to perform their obligations herein and to
take, or cause to be taken, or do, or cause to be done, all things necessary,
proper or advisable under applicable law to obtain all regulatory approvals and
satisfy all conditions to the obligations of the parties under this Agreement
and to cause the Merger and the other transactions contemplated herein to be
effected on or prior to January 30, 1998 in accordance with the terms hereof and
shall cooperate fully with each other and their respective officers, directors,
employees, agents, counsel, accountants and other designees in connection with
any steps required to be taken as a part of their respective obligations under
this Agreement, including, without limitation:
 
          (i) ATI and Parent shall promptly make their respective filings and
     submissions and shall take, or cause to be taken, all actions and do, or
     cause to be done, all things necessary, proper or advisable under
     applicable laws and regulations to obtain any required approval of any
     federal, state or local governmental agency or regulatory body with
     jurisdiction over the transactions contemplated by this Agreement.
 
          (ii) In the event any claim, action, suit, investigation or other
     proceeding by any governmental body or regulatory authority is commenced
     which questions the validity or legality of the Merger or any of the other
     transactions contemplated hereby or seeks damages in connection therewith,
     the parties agree to cooperate and use all reasonable efforts to defend
     against such claim, action, suit, investigation or other proceeding and, if
     an injunction or other order is issued in any such action, suit or other
     proceeding, to use
 
                                      D-43
<PAGE>   279
 
     all reasonable efforts to have such injunction or other order lifted, and
     to cooperate reasonably regarding any other impediment to the consummation
     of the transactions contemplated by this Agreement.
 
          (iii) Each party shall give prompt written notice to the other of (A)
     the occurrence, or failure to occur, of any event which occurrence or
     failure would be likely to cause any representation or warranty of ATI or
     Parent, as the case may be, contained in this Agreement to be untrue or
     inaccurate in any material respect at any time from the date hereof to the
     Effective Time or that will or may result in the failure to satisfy any of
     the conditions specified in Article 6 hereof and (B) any failure of ATI or
     Parent, as the case may be, to comply with or satisfy any covenant,
     condition or agreement to be complied with or satisfied by any of them
     hereunder.
 
          (iv) Without the prior written consent of Parent, ATI will not
     terminate any employee if such termination would result in the payment of
     any amounts pursuant to "change in control" provisions of any employment
     agreement or arrangement.
 
     SECTION 5.5.  Public Announcements.  The timing and content of all
announcements regarding any aspect of this Agreement or the Merger to the
financial community, government agencies, employees or the general public shall
be mutually agreed upon in advance (unless Parent or ATI are advised by counsel
that any such announcement or other disclosure not mutually agreed upon in
advance is required to be made by law and then only after making a reasonable
attempt to comply with the provisions of this Section 5.5).
 
     SECTION 5.6.  Supplements to Disclosure Letters.  From time to time prior
to the Effective Time, ATI and Parent will each promptly supplement or amend the
respective disclosure letters which will be delivered pursuant to this Agreement
with respect to any matter hereafter arising which, if existing or occurring at
the date of this Agreement, would have been required to be set forth or
described in any such disclosure letter or which is necessary to correct any
information in any such disclosure letter which has been rendered inaccurate
thereby. No supplement or amendment to any such disclosure letter shall have any
effect for the purpose of determining satisfaction of the conditions set forth
in Sections 6.2 or 6.3 of this Agreement.
 
     SECTION 5.7.  Continuation of Business.  Parent and Surviving Corporation
each agree to continue the historic business of ATI or use a significant portion
of ATI's historic business assets to the extent necessary to fulfill the
continuity requirements for reorganizations under Section 368 of the Code as
described in Treas. Reg. SS. 1.368-1(d).
 
     SECTION 5.8.  Stockholder Matters.  ATI shall call a special meeting of its
stockholders to be held as soon as practicable after the date hereof for the
purpose of voting upon this Agreement and the Merger and, through its Board of
Directors, recommend to its stockholders approval of this Agreement and the
Merger at such meeting.
 
     SECTION 5.9.  Indemnification Against Certain Liabilities.  Parent agrees
that all rights to indemnification and all limitations of liability existing in
favor of the officers and directors of ATI ("Indemnified Parties") as provided
in its certificate of incorporation and bylaws as of the date hereof with
respect to matters occurring prior to the Effective Time shall survive the
Merger and shall continue in full force and effect, without any amendment
thereto, for a period of not less than six (6) years from the Effective Time;
provided, however, that all rights to any indemnification in respect of any
claim asserted or made within such period shall continue until the final
disposition of such claim.

jurisdiction to the effect that the Merger may not be consummated as herein
provided, (ii) any proceeding or lawsuit shall have been commenced by any

contemplated hereby are special, unique and of extraordinary character, and

and this Section 8.3, all of which shall survive the termination.
Notwithstanding the foregoing, nothing contained herein shall relieve any party
from liability for any breach of any covenant or agreement in this Agreement.

                                      D-50
<PAGE>   286
 
          (ii) An Indemnification Claim shall be made by an ATI Indemnitee by
     delivery of a written notice to the Parent Indemnitors Representative
     requesting indemnification and specifying the basis on which
     indemnification is sought and the amount of asserted Losses and, in the
     case of a Third Party Claim, containing (by attachment or otherwise) such
     other information as such Indemnitee shall have concerning such Third Party
     Claim.
 
          (iii) If the Indemnification Claim involves a Third Party Claim, the
     procedures set forth in Section 9.5 hereof shall also be observed by the
     Indemnitee and the Indemnitors Representative.
 
          (iv) If the Indemnification Claim involves a matter other than a Third
     Party Claim, the Indemnitors Representative shall have thirty (30) days to
     object to such Indemnification Claim by delivery of a written notice of
     such objection to such Indemnitee specifying in reasonable detail the basis
     for such objection. Failure to timely so object shall constitute a final
     and binding acceptance of the Indemnification Claim by the Indemnitors
     Representative on behalf of all the subject Indemnitors, and the
     Indemnification Claim shall be paid in accordance with subsection (v)
     hereof.
 
          (v) Upon determination of the amount of an Indemnification Claim,
     whether by agreement between the Indemnitors Representative and the
     Indemnitee or otherwise, the Indemnitors shall pay the amount of such
     Indemnification Claim within ten (10) days of the date such amount is
     determined.
 
     SECTION 9.5.  Third Party Claims.  The obligations and liabilities of the
parties hereunder with respect to a Third Party Claim shall be subject to the
following terms and conditions:
 
          (i) The Indemnitee shall give the applicable Indemnitors
     Representative written notice of a Third Party Claim promptly after receipt
     by the Indemnitee of notice thereof, and the Indemnitors Representative, on
     behalf of the Indemnitors, may undertake the defense, compromise and
     settlement thereof by representatives of its own choosing reasonably
     acceptable to the Indemnitee. The failure of the Indemnitee to notify the
     Indemnitors Representative of such claim shall not relieve the Indemnitors
     of any liability that they may have with respect to such claim except to
     the extent the Indemnitors Representative demonstrates that the defense of
     such claim is prejudiced by such failure. The assumption of the defense,
     compromise and settlement of any such Third Party Claim by the Indemnitors
     Representative shall be an acknowledgment of the obligation of the
     Indemnitors to indemnify the Indemnitee with respect to such claim
     hereunder. If the Indemnitee desires to participate in, but not control,
     any such defense, compromise and settlement, it may do so at its sole cost
     and expense. If, however, the Indemnitors Representative fails or refuses
     to undertake the defense of such Third Party Claim within ten (10) days
     after written notice of such claim has been given to the Indemnitors
     Representative by the Indemnitee, the Indemnitee shall have the right to
     undertake the defense, compromise and settlement of such claim with counsel
     of its own choosing, which counsel shall be reasonably satisfactory to the
     Indemnitors Representative and which settlement, if any, is reasonably
     satisfactory to the Indemnitor Representative. In the circumstances
     described in the immediately preceding sentence, the Indemnitee shall,
     promptly upon its assumption of the defense of such claim, make an
     Indemnification Claim as specified in Section 9.3 which shall be deemed an
     Indemnification Claim that is not a Third Party Claim for the purposes of
     the procedures set forth herein.
 
          (ii) If, in the reasonable opinion of the Indemnitee, any Third Party
     Claim or the litigation or resolution thereof involves an issue or matter
     which could have a material adverse effect on the business, operations,
     assets, properties or prospects of the Indemnitee (including, without
     limitation, the administration of the tax returns and responsibilities
     under the tax laws of the Indemnitee), the Indemnitee shall have the right
     to control the defense, compromise and settlement of such Third Party Claim
     undertaken by the Indemnitors Representative, and the reasonable costs and
     expenses of the Indemnitee in connection therewith shall be included as
     part of the indemnification obligations of the Indemnitors hereunder. If
     the Indemnitee shall elect to exercise such right, the Indemnitors
     Representative shall have the right to participate in, but not control, the
     defense, compromise and settlement of such Third Party Claim at its sole
     cost and expense.
 
                                      D-51
<PAGE>   287
 
          (iii) No settlement of a Third Party Claim involving the asserted
     liability of the Indemnitors under this Article 9 shall be made without the
     prior written consent by or on behalf of the Indemnitors Representative,
     which consent shall not be unreasonably withheld or delayed. Consent shall
     be presumed in the case of settlements of $20,000 or less where the
     Indemnitors Representative has not responded within five (5) business days
     of notice of a proposed settlement. If the Indemnitors Representative
     assumes the defense of such a Third Party Claim, (A) no compromise or
     settlement thereof may be effected by the Indemnitors Representative
     without the Indemnitee's consent unless (i) there is no finding or
     admission of any violation of law or any violation of the rights of any
     person and no effect on any other claim that may be made against the
     Indemnitee, (ii) the sole relief provided is monetary damages that are paid
     in full by the Indemnitors, and (iii) the compromise or settlement
     includes, as an unconditional term thereof, the giving by the claimant or
     the plaintiff to the Indemnitee of a release, in form and substance
     satisfactory to the Indemnitee, from all liability in respect of such Third
     Party Claim, and (B) the Indemnitee shall have no liability with respect to
     any compromise or settlement thereof effected without its consent.
 
          (iv) In connection with the defense, compromise or settlement of any
     Third Party Claim, the parties to this Agreement shall execute such powers
     of attorney as may reasonably be necessary or appropriate to permit
     participation of counsel selected by any party hereto and, as may
     reasonably be related to any such claim or action, shall provide access to
     the counsel, accountants and other representatives of each party during
     normal business hours to all properties, personnel, books, tax records,
     contracts, commitments and all other business records of such other party
     and will furnish to such other party copies of all such documents as may
     reasonably be requested (certified, if requested), provided that the
     receiving party agrees to maintain the confidential nature of the
     information provided to the receiving party to the reasonable satisfaction
     of the party providing such information.
 
     SECTION 9.6.  Rights and Remedies Exclusive.  Except as expressly provided
in Section 5.3 hereof and except to the extent the same shall have been the
result of common-law fraud, intentional omission or deliberate concealment by or
on behalf of an Indemnitor, the rights of the Indemnitees under this Article 9
shall be the exclusive rights and remedies of the Indemnitees for any breach of
the representations and warranties on the part of any Indemnitor; provided,
however, that this Section 9.6 does not limit the rights of any party under any
of the Exhibits hereto.
 
     SECTION 9.7.  Survival.  Subject to Section 9.8 hereof, all
representations, warranties and agreements contained in this Agreement or in any
certificate, schedule or exhibit delivered pursuant to this Agreement, in each
case as supplemented or amended by the respective ATI's or the Parent's
Disclosure Letter, as amended from time to time prior to the Effective Time,
shall survive the Closing notwithstanding any investigation conducted with
respect thereto or any knowledge acquired as to the accuracy or inaccuracy of
any such representation or warranty.
 
     SECTION 9.8.  Time Limitations.
 
          (i) If the Closing occurs, the ATI Indemnitors shall have no liability
     under Section 9.2, unless on or before the 18th month anniversary of the
     Closing Date the ATI Indemnitors Representative is given notice asserting
     an Indemnification Claim with respect thereto; provided, however, that an
     Indemnification Claim based upon a breach of the representations and
     warranties of ATI contained in (a) Sections 3.1, 3.2, 3.3, 3.4(b) and 3.16
     may be made at any time except as limited by law, (b) Section 3.11 may be
     made at any time prior to the expiration of the applicable statutes of
     limitations relative to the liability relating thereto; and (c) Section
     3.17 may be made at any time prior to the fifth anniversary of the Closing
     Date.
 
          (ii) If the Closing occurs, the Parent Indemnitors shall have no
     liability under Section 9.3, unless on or before the 18th month anniversary
     of the Closing Date the Parent Indemnitors are given notice asserting an
     Indemnification Claim with respect thereto; provided, however, that an
     Indemnification Claim based upon a breach of the representations and
     warranties of the Parent Indemnitors contained in (a) Sections 4.1, 4.2,
     4.3 and 4.4 may be made at any time except as limited by law and (b)
     Section 4.9
 
                                      D-52
<PAGE>   288
 
     may be made at any time prior to the expiration of the applicable statutes
     of limitations relative to the liability relating thereto.
 
     SECTION 9.9.  Limitations as to Amount Payable by ATI Indemnitors.  The ATI
Indemnitors shall have no liability with respect to the matters described in
Section 9.2 until the total of all Losses with respect thereto (other than
Losses described in Section 9.2(v)) exceeds $100,000, in which event the ATI
Indemnitors shall be obligated to indemnify the Indemnitees as provided in this
Article 9 for all such Losses. Except as provided below in this Section 9.9, the
maximum amount of any claim against the ATI Indemnitors shall not exceed the sum
of (i) $5,000,000 and (ii) the value of the Parent Shares to be issued to the
Signing Stockholder (the "Signing Stockholder Parent Shares") where such shares
are valued at the Average Closing Price. Notwithstanding anything herein to the
contrary, satisfaction of any claim by the Parent Indemnitees under this Article
9 shall be limited to and made by a redemption of the Parent Shares and Escrow
Shares (with each such share having a value equal to the Average Closing Price)
as follows: first by a redemption of the Signing Stockholder Parent Shares and
second by a redemption of the Escrow Shares which have become releasable under
the terms of the Escrow Agreement to the ATI Stockholders; provided, however,
that if the conditions precedent to the release of all or any portion of the
Escrow Shares have been satisfied, then the satisfaction of any claim by the
Parent Indemnitees under this Article 9 shall be made first by a redemption of
Escrow Shares to the extent released and second by a redemption of the Signing
Stockholder Parent Shares. The limitations set forth above in this Section 9.9
with respect to the aggregate amount of claims made against the ATI Indemnitors
(but not the method of satisfying such claims pursuant to the immediately
preceding sentence hereof) shall not apply to any intentional misrepresentation
or breach of warranty by or on behalf of ATI or any intentional failure to
perform or comply with any covenant or agreement of ATI, and ATI shall be liable
for all Losses with respect thereto.
 
     SECTION 9.10.  Limitations as to Amount Payable by Parent and Surviving
Corporation.  The Parent Indemnitors shall have no liability with respect to the
matters described in Section 9.2 until the total of all Losses with respect
thereto exceeds $50,000, in which event the Parent Indemnitors shall be
obligated to indemnify the ATI Indemnitees as provided in this Article 9 for all
such Losses up to an aggregate of $2,000,000.
 
     SECTION 9.11.  Subrogation.  Upon payment in full of any Indemnification
Claim, whether such payment is effected by set-off or otherwise, or the payment
of any judgment or settlement with respect to a Third Party Claim, the
Indemnitors shall be subrogated to the extent of such payment to the rights of
the Indemnitee against any person or entity with respect to the subject matter
of such Indemnification Claim or Third Party Claim.
 
     SECTION 9.12.  Appointment of ATI Indemnitors Representative.  Each ATI
Indemnitor constitutes and appoints the ATI Indemnitors Representative as his
true and lawful attorney-in-fact to act for and on behalf of such ATI Indemnitor
in all matters relating to or arising out of this Article 9 and the liability or
asserted liability of such ATI Indemnitor hereunder, including specifically, but
without limitation, accepting and agreeing to the liability of such ATI
Indemnitor with respect to any Indemnification Claim, objecting to any
Indemnification Claim, disputing the liability of such ATI Indemnitor, or the
amount of such liability, with respect to any Indemnification Claim and
prosecuting and resolving such dispute as herein provided, accepting the
defense, compromise and settlement of any Third Party Claim on behalf of such
ATI Indemnitor or refusing to accept the same, settling and compromising the
liability of such ATI Indemnitor hereunder, instituting and prosecuting such
actions (including arbitration proceedings) as the ATI Indemnitors
Representative shall deem appropriate in connection with any of the foregoing
and retaining counsel, accountants, appraisers and other advisers in connection
with any of the foregoing, all for the account of the ATI Indemnitor, such ATI
Indemnitor agreeing to be fully bound by the acts, decisions and agreements of
the ATI Indemnitor Representative taken and done pursuant to the authority
herein granted. Each ATI Indemnitor hereby agrees to indemnify and to save and
hold harmless the ATI Indemnitors Representative from any liability incurred by
the ATI Indemnitors Representative based upon or arising out of any act, whether
of omission or commission, of the ATI Indemnitors Representative pursuant to the
authority herein granted, other than acts, whether of omission or commission, of
the ATI Indemnitors Representative that constitute gross negligence or willful
misconduct in the exercise by the ATI Indemnitors Representative of the
                                      D-53
<PAGE>   289
 
authority herein granted. The death or incapacity of any ATI Indemnitor shall
not terminate the authority and agency of the ATI Indemnitors Representative. In
the event of the resignation of an ATI Indemnitors Representative, the resigning
ATI Indemnitors Representative shall appoint a successor either from among the
ATI Indemnitors or who shall otherwise be acceptable to Parent and who shall
agree in writing to accept such appointment, and the resigning ATI Indemnitors
Representative's resignation shall not be effective until such a successor shall
exist. If an ATI Indemnitors Representative should die or become incapacitated,
his successor shall be appointed within thirty (30) days of his death or
incapacity by a majority of the ATI Indemnitors, and such successor either shall
be a Stockholder or shall otherwise be acceptable to Parent. The choice of a
successor ATI Indemnitors Representative appointed in any manner permitted above
shall be final and binding upon all of the ATI Indemnitors. The decisions and
actions of any successor ATI Indemnitors Representative shall be, for all
purposes, those of an ATI Indemnitors Representative as if originally named
herein.
 
     SECTION 9.13.  Payment.  In the event that any Indemnitor is required to
make any payment under this Article 9, such party shall promptly pay the
Indemnitee the amount so determined. If there should be a dispute as to the
amount or manner of determination of any indemnity obligation owed under this
Article 9, the Indemnitor shall nevertheless pay when due such portion, if any,
of the obligation as shall not be subject to dispute. The difference, if any,
between the amount of the obligation ultimately determined as properly payable
under this Article 9 and the portion, if any, theretofore paid shall bear
interest as provided below. If all or part of any indemnification obligation
under this Agreement is not paid when due, then the Indemnitor shall pay the
Indemnitee interest on the unpaid amount of the obligation for each day from the
date the amount became due until payment in full, payable on demand, at the
fluctuating rate per annum which at all times shall be the lowest rate of
interest generally charged from time to time by Morgan Guaranty Trust Company of
New York and publicly announced by such bank as its so-called "prime rate."

                              EMPLOYMENT AGREEMENT
 
     THIS EMPLOYMENT AGREEMENT ("Agreement") is made and entered into this 29th
day of January, 1998, by and between ERNEST H. LIN, a resident of the
Commonwealth of Massachusetts ("Employee"), CELLULAR INFRASTRUCTURE SUPPLY,
INC., a Delaware corporation ("Company"), and WORLD ACCESS, INC., a Delaware
corporation and the parent of the Company (the "Parent").
 
                              W I T N E S S E T H:
 
     WHEREAS, the Company and Employee each desire to enter into this Agreement,
pursuant to which the Company will employ the Employee on the terms and
conditions hereinafter set forth and to make certain other agreements;
 
     NOW, THEREFORE, in consideration of the premises and of the promises and
agreement hereinafter set forth, the parties hereto, intending to be legally
bound, do hereby agree as follows:
 
SECTION 1.  Employment.
 
     1.1. General Employment.  Subject to the terms hereof, the Company hereby
employs Employee, and Employee hereby accepts such employment. Employee will
devote his full business time and best efforts to rendering services on behalf
of the Company.
 
SECTION 2.  Position.
 
     2.1. Title and Duties.  Employee will serve as the President of the
Advanced TechCom Division of the Company (the "ATI Division") and, as such,
Employee will report to the President of the Transport and Access Group of the
Parent. If, at any time after December 31, 1998, the ATI Division is not
performing in accordance with its business plan, then the Parent may remove the
Employee as President, and, if so removed, Employee shall serve as a senior
officer of the ATI Division with such title and having such duties as Employee
and Parent shall mutually agree and the successor President of the ATI Division
to be appointed by Parent shall be reasonably satisfactory to Employee. Employee
shall exercise such authority and perform such duties relating to Company as are
considered standard and typical for an officer in his position. Subject to such
travel requirements as may be reasonably necessary to the performance of
Employee's duties hereunder, Employee will be required to perform the services
and duties provided for in this Agreement only at the location of the offices of
the Company in the Boston, Massachusetts metropolitan area, or at such other
location of the Company as the Employee and the Company may mutually agree.
 
SECTION 3.  Term.
 
     3.1. Initial Term.  The employment of Employee hereunder will commence on
the date hereof (the "Effective Date") and will continue until the earlier of:
 
          (a) December 31, 1999 (the "Initial Term"); or
 
          (b) the occurrence of any of the following events: (i) the death or
     total disability of Employee (total disability meaning the failure of
     Employee to perform his normal required services hereunder at his office
     for a period of three (3) consecutive months, by reason of Employee's
     mental or physical disability as so determined by a licensed physician
     selected by the Company satisfactory to Employee);
 
             (ii) the mutual written agreement of the parties hereto to
        terminate Employee's employment hereunder; or
 
             (iii) the Company's termination of Employee's employment hereunder,
        upon thirty (30) days' prior written notice to Employee, for "good
        cause".

<PAGE>   294
 
          (c) For purposes of this Section, "good cause" for termination of
     Employee's employment will exist:
 
             (i) if Employee is convicted of (from which no appeal may be
        taken), or pleads guilty to, any act of fraud, misappropriation or
        embezzlement, or any felony;
 
             (ii) if, in the sole determination of the Board of Directors of the
        Company ("Board"), and as set forth in a written statement executed by
        the Board (not including Employee, if he is a Director), Employee has
        engaged in conduct or activities materially damaging to the business of
        the Company (it being understood, however, that neither conduct nor
        activities pursuant to Employee's exercise of his good faith business
        judgment nor unintentional physical damage to any property of the
        Company by Employee will be a ground for such a determination by the
        Board); or
 
             (iii) if Employee has failed without reasonable cause to devote his
        full business time and reasonable efforts to the business of the Company
        and, after written notice from the Company of such failure, Employee at
        any time thereafter again so fails, provided that the Company gives
        Employee notice of such failure prior to or together with any such
        notice of termination.
 
     3.2. Renewal.  The term of this Agreement will automatically renew after
the expiration of the Initial Term for one or more additional one (1) year terms
unless either party gives notice of non-renewal to the other party at least
sixty (60) days prior to the expiration of the then-existing term, in which
event this Agreement will terminate upon the expiration of the then-existing
term.
 
SECTION 4.  Compensation and Benefits.
 
     4.1. Salary.  (a) The Company will pay Employee a salary at the annual rate
of One Hundred Fifty Thousand Dollars ($150,000) payable bi-weekly in accordance
with the payroll payment practices adopted from time to time by the Company.
Employee shall also be entitled to receive an annual bonus as described in
Section 4.3 hereof.
 
     (b) The Company agrees to consider and, if it deems appropriate, to
declare, from time to time (although no more than once during each 12 month
period commencing each January 1) increases in the salary it pays Employee based
upon inflation, adjustments to the salaries of other senior management
personnel, the past performance of Employee and the contribution Employee makes
to the business and profits of the Company during the term hereof
 
     4.2. Compensation Upon Termination or During Disability.  (a) Should
Employee's employment be terminated upon the expiration of the term of this
Agreement, as set forth in Section 3.1(a) or (b)(ii), the Company shall pay
Employee his full salary through the date of such termination at the rate in
effect at that time, and Employee shall have the right to exercise any and all
vested stock options granted to him, pursuant to the terms and conditions of
Parent's stock option plan.
 
     (b) Should Employee's employment be terminated by reason of his death, as
set forth in Section 3.1(b)(i), the Company shall pay to such person as he shall
designate in a notice filed with the Company, or, if no such person shall be
designated, to his estate as a lump sum death benefit, his full salary to the
date of his death, in addition to any payments Employee's spouse, beneficiaries

estate or spouse, as the case may be, shall have the right to exercise any and
all vested stock options granted to Employee prior to his date of death,
pursuant to the terms and conditions of Parent's stock option plan.

as a result of incapacity due to physical or mental illness, Employee shall
continue to receive his full salary and bonus payments until Employee's
employment is terminated for total disability pursuant to Section 3.1(b)(i).
Upon termination of his employment for total disability, Employee or his
representative, as the case may be, shall have the right to exercise any and all
vested stock options granted to Employee prior to the date of his termination
for total disability, pursuant to the terms and conditions of Parent's stock
option plan.

     (e) Employee shall not be required to mitigate the amount of any payment
provided for in Section 4 of this Agreement by seeking other employment or

twenty-five percent (25%) on each of the first four (4) anniversaries of the
date of the grant.
 
     4.5. Designation of Employees to Receive Stock Options.  Upon execution of
this Agreement, the Company shall grant Employee the right to designate

     4.6. Insurance.  (a) Life and Other Insurance.  The Company will, at its
expense, provide or arrange for and keep in effect, during the term of
Employee's employment hereunder, so long as he is insurable, such group term

disability insurance, or their equivalents, as is provided from time to time for
executives of Parent and its subsidiaries holding positions and responsibilities
comparable to those of Employee.
 
     (b) Medical Insurance.  During the term of Employee's employment hereunder,
the Company will, at its expense, provide or arrange for and keep in effect,
hospitalization, major medical and similar medical and health insurance for
Employee and his family, to the same extent as is provided from time to time for
executives of Parent and its subsidiaries holding positions and responsibilities

responsibilities comparable to those of Employee. Employee shall be entitled to
leave of absence and leave for illness or temporary disability in accordance
with policies in effect for executives of Parent and its subsidiaries holding
positions and responsibilities comparable to those of Employee, and any leave on

Employee of his agreements hereunder.
 
     4.8. Retirement Benefits.  During the term of his employment hereunder,
Employee shall have the same right as other executives of Parent and its
subsidiaries holding positions and responsibilities comparable to those of

SECTION 5.  Miscellaneous.
 
     5.1. Successors; Binding Effect.  The Company shall require any successor
(whether direct or indirect, by purchase, merger, consolidation or otherwise) to
all or substantially all of the business and/or assets of the Company, by
agreement in form and substance reasonably satisfactory to Employee, to
expressly assume and agree to perform this Agreement in the same manner and to
the same extent that the Company would be required to perform it if no such
succession had taken place. Failure of the Company to obtain such agreement
prior to the effectiveness of any such succession shall be a breach of this
Agreement and shall entitle Employee to compensation from the Company in the
same amount and on the same terms as he would be entitled to hereunder if his
employment were terminated without "good cause." The date on which any such
succession becomes effective shall be deemed to be the date of Employee's
termination. This Agreement will inure to the benefit of and will be binding
upon Employee, his executor, administrator, personal representatives and
assigns, and upon the Company and its successors and assigns; provided, however,
that the obligation and duties of Employee may not be assigned or delegated.

agreements, provisions and covenants contained in this Agreement are severable

such agreement, provision and covenant constitutes an enforceable obligation
between the Company and Employee. Consequently, the parties hereto agree that
neither the invalidity nor the enforceability of any agreement, provision or
covenant of this Agreement will affect the other agreements, provisions or
covenants hereof, and this Agreement will remain in full force and effect and be
construed in all respects as if such invalid or unenforceable agreement,
provision or covenant were omitted.
 
     5.4. Headings.  The section and paragraph headings contained in this
Agreement are for reference purposes only and will not affect in any way the
meaning or interpretation of this Agreement.

or be construed as a waiver of any prior or subsequent breach of the same or any
other provision, agreement or covenant by Employee.

                                ESCROW AGREEMENT
 
     THIS ESCROW AGREEMENT (the "Agreement") is made and entered into as of the
29th day of January, 1998, by and among WORLD ACCESS, INC., a Delaware
corporation ("Parent"), CELLULAR INFRASTRUCTURE SUPPLY, INC., a Delaware
corporation (the "Surviving Corporation"), CAUTHEN & FELDMAN, P.A., a Florida
professional association (the "Escrow Agent"), and each of the stockholders of
Advanced TechCom, Inc., a Delaware corporation ("ATI"), listed on Schedule 1
hereto (each such person a "Stockholder" and, collectively, the "Stockholders").
 
                              W I T N E S S E T H:
 
     WHEREAS, the Stockholders are all of the holders of the Series A
Convertible Preferred Stock, $.10 par value per share, of ATI;
 
     WHEREAS, certain of the parties hereto, among others, have entered into an
Agreement and Plan of Merger dated as of December 24, 1997, a copy of which is
attached hereto as Exhibit A and incorporated herein by reference (the "Merger
Agreement"), pursuant to which, among other things, ATI will be merged with and
into the Surviving Corporation, a wholly-owned subsidiary of Parent, with the
separate corporate existence of ATI then terminating (the "Merger"); and
 
     WHEREAS, Section 2.1(a)(i)(B) of the Merger Agreement requires Parent to
deliver 209,050 shares (the "Escrow Shares") of its common stock, $.01 par value
per share, to the Escrow Agent, to hold and distribute such shares pursuant to
the terms hereof;
 
     NOW, THEREFORE, in consideration of the premises and the mutual covenants
hereinafter set forth, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto agree as follows:
 
     1. Escrow Deposit.  Within ten (10) business days of the execution hereof,
Parent shall cause to be delivered to the Escrow Agent, to be held and
distributed as hereinafter provided, a stock certificate issued in the names of
the Stockholders representing the Escrow Shares, and each of the Stockholders
shall deliver to the Escrow Agent a stock power duly endorsed in blank with
signature guarantee with respect to the Escrow Shares.
 
     2. Property Distributed in Respect of Escrow Shares.  During the term
hereof, the Escrow Agent shall receive all of the money, securities, rights or
property distributed in respect of the Escrow Shares, including any such
property distributed as dividends, such property to be held and administered as
herein provided (the "Share Proceeds").
 
     3. Voting and Transfer of Escrow Shares.  For so long as the Escrow Shares
are held by the Escrow Agent, the Stockholders shall be entitled to exercise any
and all voting or consensual rights and powers relating to or pertaining to the
Escrow Shares so held by the Escrow Agent. No Stockholder shall transfer the
Escrow Shares, or any interest therein, during the term of this Agreement,
except under the laws of descent and distribution.
 
     4. Fees of Escrow Agent.  The Escrow Agent shall be entitled to a fee (the
"Escrow Fee") based upon its normal hourly billing rate as compensation for its
services hereunder. The Escrow Fee shall be payable by Parent upon demand
therefor from the Escrow Agent. The Parent upon demand therefor shall reimburse
the Escrow Agent for all costs and expenses incurred by the Escrow Agent in
connection with the performance of its duties hereunder.
 
     5. Distribution of Escrow Shares.  (a) Upon receipt of the certificates
provided in Section 7 below, the Escrow Agent shall distribute the Escrow Shares
held by it under this Agreement in the aggregate amounts (each a "Release
Amount") (together with the pro rata portion of the Share Proceeds, if any,
allocable thereto) based upon the Pre-Tax Net Income (as hereinafter defined) of
the ATI Division of the Surviving Corporation (the "ATI Division") on the
release dates set forth below (each a "Release Date") for the
                                      D-63
<PAGE>   299
 
performance period set forth below (each a "Performance Period") which
corresponds with such Release Date. Notwithstanding the foregoing, any Share
Proceeds that consist solely of cash shall be distributed to the Stockholders
promptly upon receipt thereof, and a Stockholder shall be entitled to receive
such cash in an amount equal to the aggregate of all such cash to be distributed
multiplied by the Proportionate Interest (as set forth in Column C of Schedule 1
hereto) of each such Stockholder. No fractional Escrow Shares will be released.
In lieu thereof, if a Stockholder would otherwise have been entitled to a
fractional share hereunder, then such Stockholder shall be entitled to receive
an amount in cash in lieu of such fractional share, based on a value per share
of the Escrow Shares equal to the Average Closing Price (as hereinafter defined)
and the Parent shall promptly deposit with Escrow Agent an amount sufficient to
fund all such cash amounts prior to each Release Date. Notwithstanding anything
herein to the contrary, in the event the Signing Stockholder Parent Shares (as
defined in the Merger Agreement) have been redeemed to satisfy a claim by the
Parent Indemnities (as defined in the Merger Agreement) pursuant to Article 9 of
the Merger Agreement and subsequently a Release Amount becomes releasable
hereunder, the Escrow Shares, to the extent possible, shall be released to the
Signing Stockholder (as defined in the Merger Agreement) instead of the
Stockholders so that the Signing Stockholder receives a number of shares equal
to the number of Signing Stockholder Parent Shares used to satisfy any claims by
the Parent Indemnities, with each Stockholder contributing a pro rata portion of
the Escrow Shares (together with a pro rata portion of the Share Proceeds, if
any, since the date the Signing Stockholder Parent Shares were redeemed) on the
basis of each Stockholder's Proportionate Interest.

     Notwithstanding the foregoing, if the Pre-Tax Net Income of the ATI
Division is (i) greater than $2,500,000, but less than $3,000,000, with respect
to the First Performance Period and (ii) greater than $4,000,000 with respect to
the Second Performance Period, then Parent will instruct the Escrow Agent to
release to the Stockholders on the Release Date which corresponds to the Second
Performance Period in lieu of the Release Amount otherwise releasable pursuant
hereto Escrow Shares having an aggregate value equal to (i) $3,000,000, plus
(ii) the amount equal to (A) (x) $3,000,000 less (y) the Pre-Tax Net Income for
the First Performance Period, to the extent that such amount does not exceed the
amount by which the Pre-Tax Net Income for the Second Performance exceeds
$4,000,000, multiplied by (B) 2.0. For purposes hereof, the "Average Closing
Price" shall equal $23.9177 per share.
 
          (b) Parent will determine whether to instruct the Escrow Agent to
     release the Release Amount to the Stockholders based upon the books and
     records of the ATI Division (which will be maintained in accordance with
     generally accepted accounting principles) as soon as practicable after the
     end of each Performance Period, and Parent will promptly deliver to Ernest
     H. Lin as a representative of the Stockholders (the "ATI Representative"),
     appointed pursuant to Section 6 hereof, a letter setting out in reasonable
     detail the computations made and expressing its opinion that the conditions
     for the release of the Release Amount have been satisfied in accordance
     with the requirements hereof. The computations set forth in such letter
     from Parent will be final and binding on all parties unless the ATI
     Representative shall have notified Parent in writing within ten (10) days
     after receipt of such letter that he disagrees with such computations. In
     such event, if the parties cannot agree on the computations within thirty
     (30) days after their receipt of such letter, then the Stockholders may
     retain, at their own expense, an independent public accounting firm (the
     "Accountants"), which shall have thirty (30) days in which to make its own
     calculation of Pre-Tax Net Income for the applicable Performance Period. If
     the calculations of the Accountants differ from that of Parent, then the
     parties shall negotiate in good faith for a period of ten (10) days to
     resolve any differences. If the parties are unable to resolve the dispute
     within such 10 day period, then the matter shall be submitted to an
     independent public accounting firm selected jointly by Parent and the
     Accountants within five days after the end of such ten day period. Such
     independent accounting firm shall then have thirty (30) days in which to
     make its own calculation of Pre-Tax Net Income for the applicable
     Performance Period. The cost of any such calculations by such independent
     accounting firm and the Accountants shall be paid by the Stockholders if
     its computations result in the Release Amount being the same as or less
     than that set forth in the letter from Parent or by Parent if such
     computations result in the Release Amount being greater than that set forth
     in such letter. Parent and the ATI Representative will instruct the Escrow
     Agent by delivering to it a Certificate of Instruction as set forth in
     Section 7 to release to the Stockholders the amount of Release Amount set
     forth in Parent's letter to the ATI Representative, and any additional
     amount thereafter agreed upon by the parties or computed by such
     independent accounting firm (if such computations are made) will be
     released to Stockholders promptly after delivery of the accountants' report
     and supplemental Certificates of Instruction. The Stockholders will
     promptly return to Parent any amount of the Release Amount released to them
     that is in excess of the Release Amount computed by such independent
     accounting firm if its computation is less than that set forth in the
     letter from Parent.
 
          (c) For purposes hereof, "Pre-Tax Net Income" means the income of the
     ATI Division before (i) income and deductions not related to primary
     operations (i.e., gains or losses on disposal of fixed assets and other
     miscellaneous unrelated items), (ii) taxes based on income, (iii)
     cumulative effects of accounting changes, (iv) extraordinary items and (v)
     allocations or charges of expenses to the ATI Division from Parent or any
     of its subsidiaries or affiliates unless the expense is for funds loaned
     (other than with respect to the first $5.0 million of intercompany loans
     which shall not bear interest for purposes of determining Pre-Tax Net
     Income), services rendered or goods provided in direct relation to the ATI
     Division's business at a negotiated fair market value price. In addition,
     for purposes of determining the Pre-Tax Net Income of the ATI Division,
     one-half (1/2) of the pre-tax net income of Parent or any of its
     subsidiaries (in each case as customarily determined by Parent) relating
     directly to the sales of products of Parent or any of its subsidiaries
     (other than products of the ATI Division) made directly by Mr. Lin or any
     sales person within the ATI Division shall be included in determining the
     Pre-Tax Net Income of the ATI Division.

     6. Appointment of ATI Representative.  Each Stockholder constitutes and
appoints the ATI Representative as his or her true and lawful attorney-in-fact
to act for and on behalf of such Stockholder in all matters relating to or
arising out of this Agreement, such Stockholder agreeing to be fully bound by
the acts, decisions and agreements of the ATI Representative taken and done
pursuant to the authority herein granted. Each Stockholder hereby agrees to
indemnify and to save and hold harmless the ATI Representative from any
liability incurred by the ATI Representative based upon or arising out of any
act, whether of omission or commission, of the ATI Representative pursuant to
the authority herein granted, other than acts, whether of omission or
commission, of the ATI Representative that constitute gross negligence or
willful misconduct in the exercise by the ATI Representative of the authority
herein granted. The death or incapacity of any Stockholder shall not terminate
the authority and agency of the ATI Representative. In the event of the
resignation of the ATI Representative, the resigning ATI Representative shall
appoint a successor either from among the Stockholders or who shall otherwise be
acceptable to Parent, the Surviving Corporation and the Escrow Agent, and who
shall agree in writing to accept such appointment, and the resigning ATI
Representative's resignation shall not be effective until such a successor shall
exist. If the ATI Representative should die or become incapacitated, his
successor shall be appointed within thirty (30) days of his death or incapacity
by a majority of the Stockholders, and such successor either shall be a
Stockholder or shall otherwise be acceptable to Parent, the Surviving
Corporation and the Escrow Agent. The choice of a successor ATI Representative
appointed in any manner permitted above shall be final and binding upon all of
the Stockholders. The decisions and actions of any successor ATI Representative
shall be, for all purposes, those of the ATI Representative as if originally
named herein.
 
     7. Certificates of Instruction.  (a) Within forty (40) days of the end of
each Performance Period, Parent and the ATI Representative shall deliver to the
Escrow Agent a Certificate of Instruction setting forth the Pre-Tax Net Income
of the ATI Division for each such Performance Period and, in the event that
Pre-Tax Net Income equals an amount for such Performance Period which permits
the release of Escrow Shares in accordance with Section 5 above, directing the
Escrow Agent to release to the Stockholders the number of Escrow Shares
(together with the pro rata portion of the Share Proceeds, if any) determined in
accordance with Section 5 above. In the event there is a disagreement or dispute
with respect to the determination of "Pre-Tax Net Income," Parent and the ATI
Representative may provide Escrow Agent with one or more supplemental
Certificates of Instruction with respect to any resolution of such disagreement
or dispute.
 
     (b) Upon receipt of the Certificate of Instruction, the Escrow Agent shall
cause promptly the certificate representing the Escrow Shares to be broken down
into           (     ) certificates, one of which will represent the Escrow
Shares to remain subject to the terms of this escrow and one of each of the
other           (     ) certificates will be issued to each Stockholder for that
number of the Escrow Shares to be released multiplied by the Proportionate
Interest (as set forth in Column C of Schedule 1 hereto) of each such
Stockholder, and thereafter on the Release Date the Escrow Agent shall deliver
to the Stockholders the certificates representing the Escrow Shares (together
with the pro rata portion of the Share Proceeds, if any) to be released to the
Stockholders as provided herein.
 
     (c) If, on 5:00 p.m. Eastern Standard Time on March 31, 2000, or on such
later date which is ten (10) days following the date on which a final
determination shall have been made pursuant to sub-subsection 5(b) hereof with
respect to the Pre-Tax Net Income and Parent and the ATI Representative shall
have provided Escrow Agent with a Certificate of Instruction in respect of such
final determination, the Escrow Agent continues to hold any of the Escrow
Shares, then the Escrow Agent shall deliver any such shares (together with any
Share Proceeds in the Escrow Agent's possession) to Parent, and this Agreement
shall thereupon be terminated.
 
     8. Duties of the Escrow Agent.  The acceptance by the Escrow Agent of its
duties under this Agreement is subject to the following terms and conditions,
which the parties to this Agreement hereby agree shall fully govern and control
with respect to the Escrow Agent's rights, duties, liabilities and immunities:
 
          (a) The Escrow Agent shall be protected in acting upon any written
     notice, request, waiver, consent, receipt or other paper or document which
     the Escrow Agent believes in good faith emanates from both Parent and the
     ATI Representative of the parties hereto, not only as to its due execution
     and the validity
 
                                      D-66
<PAGE>   302
 
     and effectiveness of its provisions, but also as to the truth and accuracy
     of any information contained therein. The Escrow Agent is also relieved
     from the necessity of satisfying itself as to the authority of the persons
     executing this Agreement in a representative capacity.
 
          (b) The Escrow Agent shall not be liable for any error of judgment, or
     for any act done or step taken or omitted by it in good faith, or for any
     mistake of fact or law, or for anything that it may do or refrain from
     doing in connection herewith, except for its own gross negligence or
     willful misconduct.
 
          (c) The Escrow Agent may consult with, and obtain advice from,
     independent legal counsel selected by the Escrow Agent in the event of any
     question as to any of the provisions hereof or its duties hereunder (the
     cost of obtaining such advice being borne by Parent and the Surviving
     Corporation), and it shall incur no liability and shall be fully protected
     in acting in accordance with the opinion and instructions of such counsel.
 
          (d) The Escrow Agent shall have no duties except those set forth
     herein, and the Escrow Agent shall not be subject to, or obliged to
     recognize, any other agreement between, or direction or instruction of, any
     of the parties hereto unless signed by Parent and the ATI Representative.
     The Escrow Agent shall not be bound by any notice of a claim, demand or
     objection with respect to the Escrow Shares or any waiver, modification,
     termination or rescission of this Agreement, unless received by it in
     writing signed by Parent and the ATI Representative, and, if its duties
     herein are materially increased, unless it shall have given its consent
     thereto.
 
          (e) If any dispute arises over disbursement of, or conflicting claims
     to, the Escrow Shares, then the Escrow Agent may interplead such contested
     Escrow Shares into a court of proper jurisdiction of its choosing, and
     thereupon the Escrow Agent shall be fully and completely discharged of its
     duties as escrow agent with respect to such contested Escrow Shares and
     Share Proceeds.
 
     9. Indemnification of the Escrow Agent.  Except as otherwise expressly
provided by Section 4 hereof, Parent, the Surviving Corporation and the
Stockholders jointly and severally agree to indemnify, defend and hold harmless
the Escrow Agent from any and all costs, expenses, damages or liability of any
kind whatsoever (including reasonable legal fees) arising by virtue of its
services as escrow agent hereunder, except for liabilities due to the Escrow
Agent's gross negligence or willful misconduct; provided, however, that the
Stockholders shall have no obligation to indemnify the Escrow Agent for any
costs, expenses, damages or liability arising out of any claims made by the
Stockholders.
 
     10. Notice.  All notices and other communications hereunder shall be in
writing and shall be deemed given if (a) delivered by hand, (b) mailed by
registered or certified mail (return receipt requested) or (c) telecommunicated

                         REGISTRATION RIGHTS AGREEMENT
 
     This REGISTRATION RIGHTS AGREEMENT (the "Agreement") is made and entered
into as of the 29th day of January 1998, by and among WORLD ACCESS, INC., a
Delaware corporation (the "Company"), and each of the stockholders of Advanced
TechCom, Inc., a Delaware corporation ("ATI"), listed on Schedule 1 hereto (each
such person a "Seller" and, collectively, the "Sellers").
 
     IN CONSIDERATION of the mutual promises and covenants set forth herein, and
intending to be legally bound, the parties hereto hereby agree as follows:
 
1. RESTRICTIONS ON TRANSFERABILITY OF SECURITIES; REGISTRATION RIGHTS
 
     1.1 Certain Definitions.  Any capitalized terms used herein without
definition shall have the meaning ascribed to such terms in the Agreement and
Plan of Merger dated as of December 24, 1997 to which the Company and certain
other persons are parties relating to the merger of Advanced TechCom, Inc., a
Delaware corporation, with and into Cellular Infrastructure Supply, Inc., a
wholly-owned subsidiary of the Company (the "Merger Agreement"). In addition,
the following terms shall have the meanings set forth below:
 
          (a) "Holder" shall mean any Seller who holds Registrable Securities
     and any holder of Registrable Securities to whom the rights conferred by
     this Agreement have been transferred in compliance with Section 1.2 hereof.
 
          (b) "Other Stockholders" shall mean persons who, by virtue of
     agreements with the Company other than this Agreement, are entitled to
     include their securities in certain registrations hereunder.
 
          (c) "Registrable Securities" shall mean shares of Parent Common Stock
     issued to the Sellers pursuant to Section 2.1(a)(i)(A) of the Merger
     Agreement, provided that Registrable Securities shall not include (i) any
     shares of Parent Common Stock held in escrow pursuant to Section 2.1(b) of
     the Merger Agreement or (ii) any shares of Parent Common Stock which have
     previously been registered or which have been sold to the public or which
     have been sold in a private transaction in which the transferor's rights
     under this Agreement are not assigned.
 
          (d) The terms "register," "registered" and "registration" shall refer
     to a registration effected by preparing and filing a registration statement
     in compliance with the Securities Act of 1933, as amended (the "Securities
     Act"), and applicable rules and regulations thereunder and the declaration
     or ordering of the effectiveness of such registration statement.
 
          (e) "Registration Expenses" shall mean all expenses incurred in
     effecting any registration pursuant to this Agreement, including, without
     limitation, all registration, qualification, and filing fees, printing
     expenses, escrow fees, fees and disbursements of counsel for the Company
     and one counsel selected to represent the Holders, which counsel shall be
     reasonably satisfactory to the Company, blue sky fees and expenses, and
     expenses of any regular or special audits incident to or required by any
     such registration, but shall not include (i) Selling Expenses, (ii) the
     compensation of regular employees of the Company, which shall be paid in
     any event by the Company, and (iii) blue sky fees and expenses incurred in
     connection with the registration or qualification of any Registrable
     Securities in any state, province or other jurisdiction in a registration
     pursuant to Section 1.3 hereof to the extent that the Company shall
     otherwise be making no offers or sales in such state, province or other
     jurisdiction in connection with such registration.
 
          (f) "Restricted Securities" shall mean any Registrable Securities
     required to bear the legend set forth in Section 1.2(c) hereof.
 
          (g) "Rule 144" shall mean Rule 144 as promulgated by the SEC under the
     Securities Act, as such Rule may be amended from time to time, or any
     similar successor rule that may be promulgated by the SEC.
 
                                      D-71
<PAGE>   307
 
          (h) "Rule 145" shall mean Rule 145 as promulgated by the SEC under the
     Securities Act, as such Rule may be amended from time to time, or any
     similar successor rule that may be promulgated by the SEC.

          (j) "Selling Expenses" shall mean all underwriting discounts, selling
     commissions and stock transfer taxes applicable to the sale of Registrable
     Securities.
 
     1.2 Restrictions on Transfer.  (a) Each Holder agrees not to make any
disposition of all or any portion of the Registrable Securities unless and until
(i) there is then in effect a registration statement under the Securities Act
covering such proposed disposition and such disposition is made in accordance
with such registration statement, or (ii) (A) such Holder shall have notified
the Company of the proposed disposition and shall have furnished the Company
with a detailed statement of the circumstances surrounding the proposed
disposition and (B) if reasonably requested by the Company, such Holder shall
have furnished the Company with an opinion of counsel, reasonably satisfactory
to the Company, that such disposition will not require registration of such
shares under the Securities Act, it being understood that the Company will not
require opinions of counsel for transactions made pursuant to Rule 144 except in
unusual circumstances.
 
     (b) Notwithstanding the provisions of subparagraphs (i) and (ii) of
paragraph (a) above, no such registration statement or opinion of counsel shall
be necessary for a transfer by a Holder which is (A) a partnership to its
partners in accordance with their partnership interests, (B) a limited liability
company to its members in accordance with their member interests or (C) to the
Holder's family member or a trust for the benefit of an individual Holder or one
or more of his family members, provided the transferee will be subject to the
terms of this Section 1.2 to the same extent as if he were an original Holder
hereunder.
 
     (c) Each certificate representing Registrable Securities shall (unless
otherwise permitted by the provisions of this Agreement) be stamped or otherwise
imprinted with a legend substantially similar to the following (in addition to
any legend required under applicable state securities laws):
 
     THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD OR TRANSFERRED, ASSIGNED, PLEDGED
OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER SUCH ACT OR UNLESS THE COMPANY
HAS RECEIVED AN OPINION OF COUNSEL OR OTHER EVIDENCE, SATISFACTORY TO THE
COMPANY AND ITS COUNSEL, THAT SUCH REGISTRATION IS NOT REQUIRED.
 
     (d) The Company shall be obligated to promptly reissue unlegended
certificates at the request of any Holder thereof if the Holder shall have
obtained an opinion of counsel (which counsel may be counsel to the Company)
reasonably acceptable to the Company to the effect that the securities proposed
to be disposed of may lawfully be so disposed of in compliance with the
Securities Act without registration, qualification or legend.
 
     (e) Any legend endorsed on an instrument pursuant to applicable state
securities laws and the stop-transfer instructions with respect to such
securities shall be removed upon receipt by the Company of an order of the
appropriate blue sky authority authorizing such removal or if the Holder shall
request such removal and shall have obtained and delivered to the Company an
opinion of counsel reasonably acceptable to the Company to the effect that such
legend and/or stop-transfer instructions are no longer required pursuant to
applicable state securities laws.
 
     1.3 Company Registration.  (a) Right to Piggyback. If at any time prior to
the one year anniversary of the date hereof the Company shall determine to
register any of shares of its common stock, $.01 par value per share, either for
its own account or the account of a security holder or holders exercising their
respective demand registration rights, other than a registration relating solely
to employee benefit plans, or a registration relating solely to a Rule 145
transaction, or a registration on any registration form that does not permit
secondary sales, the Company will:
 
                                      D-72
<PAGE>   308
 
          (i) promptly give to each Holder written notice thereof, which notice
     briefly describes the Holders' rights under this Section 1.3 (including
     notice deadlines); and
 
          (ii) use its best efforts to include in such registration (and any
     related filing or qualification under applicable blue sky laws), except as
     set forth in Section 1.3(b) below, and in any underwriting involved
     therein, all the Registrable Securities specified in a written request or
     requests, made by any Holder and received by the Company within ten (10)
     days after the written notice from the Company described in clause (i)
     above is mailed or delivered by the Company, provided that such Holders
     shall have requested for inclusion in such registration at least fifty-one
     (51%) of the aggregate number of the Registrable Securities which have been
     issued to the Holders prior to the date of such written request. Such
     written request may specify all or a part of a Holder's Registrable
     Securities.
 
     (b) Underwriting. If the registration of which the Company gives notice is
for a registered public offering involving an underwriting, the Company shall so
advise the Holders as a part of the written notice given pursuant to Section
1.3(a)(i). In such event, the right of any Holder to registration pursuant to
this Section 1.3 shall be conditioned upon such Holder's participation in such
underwriting and the inclusion of such Holder's Registrable Securities in the
underwriting to the extent provided herein. All Holders proposing to distribute
their securities through such underwriting shall (together with the Company and
the other holders of securities of the Company with registration rights to
participate therein distributing their securities through such underwriting)
enter into an underwriting agreement in customary form with the representative
of the underwriter or underwriters selected by the Company.
 
     Notwithstanding any other provision of this Section 1.3, if the
representative of the underwriters advises the Company in writing that marketing
factors require a limitation on the number of shares to be underwritten, the
representative may (subject to the limitations set forth below) exclude all
Registrable Securities from, or limit the number of Registrable Securities to be
included in, the registration and underwriting. The Company shall so advise all
Holders of securities requesting registration, and the number of shares of
securities that are entitled to be included in the registration and underwriting
shall be allocated first to the Company for securities being sold for its own
account and thereafter as set forth in Section 1.10. If any person does not
agree to the terms of any such underwriting, he shall be excluded therefrom by
written notice from the Company or the underwriter. Any Registrable Securities
or other securities excluded or withdrawn from such underwriting shall be
withdrawn from such registration.
 
     If shares are so withdrawn from the registration and if the number of
shares of Registrable Securities to be included in such registration was
previously reduced as a result of marketing factors, the Company shall then
offer to all persons who have retained the right to include securities in the
registration the right to include additional securities in the registration in
an aggregate amount equal to the number of shares so withdrawn, with such shares
to be allocated among the persons requesting additional inclusion in accordance
with Section 1.10. hereof.
 
     1.4 Expenses of Registration.  All Registration Expenses incurred in
connection with any registration, qualification or compliance pursuant to
Section 1.3 hereof shall be borne by the Company. All Selling Expenses relating
to securities so registered shall be borne by the holders of such securities pro
rata on the basis of the number of shares of securities so registered on their
behalf.
 
     1.5 Registration Procedures.  In the case of each registration effected by
the Company pursuant to Section 1.3 hereof, the Company will keep each Holder
advised in writing as to the initiation of each registration and as to the
completion thereof. At its expense, the Company will use its best efforts to:
 
          (a) keep such registration effective for a period of one hundred
     twenty (120) days or until the Holder or Holders have completed the
     distribution described in the registration statement relating thereto,
     whichever first occurs;
 
          (b) prepare and file with the SEC such amendments and supplements to
     such registration statement and the prospectus used in connection with such
     registration statement as may be necessary to comply with the provisions of
     the Securities Act with respect to the disposition of all securities
     covered by such registration statement;
                                      D-73
<PAGE>   309
 
          (c) furnish such number of prospectuses and other documents incident
     thereto, including any amendment of or supplement to the prospectus, as a
     Holder from time to time may reasonably request;
 
          (d) notify each Holder of Registrable Securities covered by such
     registration statement at any time when a prospectus relating thereto is
     required to be delivered under the Securities Act of the happening of any
     event as a result of which the prospectus included in such registration
     statement, as then in effect, includes an untrue statement of a material
     fact or omits to state a material fact required to be stated therein or
     necessary to make the statements therein not misleading or incomplete in
     the light of the circumstances then existing, and at the request of any
     such Holder, prepare and furnish to such Holder a reasonable number of
     copies of a supplement to or an amendment of such prospectus as may be
     necessary so that, as thereafter delivered to the purchasers of such
     Registrable Securities, such prospectus shall not include an untrue
     statement of a material fact or omit to state a material fact required to
     be stated therein or necessary to make the statements therein not
     misleading or incomplete in the light of the circumstances then existing;
     provided, however, the Company shall not be obligated to prepare and
     furnish any such prospectus supplements or amendments relating to any
     material nonpublic information at any such time as the Board of Directors
     of the Company has determined that, for good business reasons, the
     disclosure of such material nonpublic information at that time is contrary
     to the best interests of the Company in the circumstances and is not
     otherwise required under applicable law (including applicable securities
     laws);
 
          (e) cause all such Registrable Securities registered pursuant
     hereunder to be listed on each securities exchange and/or included in any
     national quotation system on which similar securities issued by the Company
     are then listed or included;
 
          (f) provide a transfer agent and registrar for all Registrable
     Securities registered pursuant to such registration statement and a CUSIP
     number for all such Registrable Securities, in each case not later than the
     effective date of such registration; and
 
          (g) otherwise use its best efforts to comply with all applicable rules
     and regulations of the SEC, and make available to its security holders, as
     soon as reasonably practicable, an earnings statement covering the period
     of at least twelve (12) months, but not more than eighteen months,
     beginning with the first month after the effective date of the registration
     statement, which earnings statement shall satisfy the provisions of Section
     11(a) of the Securities Act.
 
     1.6 Indemnification.  (a) The Company will indemnify each Holder, each of
its officers, directors and partners, legal counsel, and accountants and each
person controlling such Holder within the meaning of Section 15 of the
Securities Act, with respect to which registration, qualification, or compliance
has been effected pursuant to this Section 1, and each underwriter, if any, and
each person who controls within the meaning of Section 15 of the Securities Act
any underwriter, against all expenses, claims, losses, damages, and liabilities
(or actions, proceedings, or settlements in respect thereof) arising out of or
based on any untrue statement (or alleged untrue statement) of a material fact
contained in any prospectus, offering circular, or other document (including any
related registration statement, notification, or the like) incident to any such
registration, qualification, or compliance, or based on any omission (or alleged
omission) to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, or any violation by the
Company of the Securities Act or any rule or regulation thereunder applicable to
the Company or relating to action or inaction required of the Company in
connection with any such registration, qualification, or compliance, and will
reimburse each such Holder, each of its officers, directors, partners, legal
counsel, and accountants and each person controlling such Holder, each such
underwriter, and each person who controls any such underwriter, for any legal
and any other expenses reasonably incurred in connection with investigating and
defending or settling any such claim, loss, damage, liability, or action,
provided that the Company will not be liable in any such case to the extent that
any such claim, loss, damage, liability, or expense arises out of or is based on
any untrue statement or omission based upon written information furnished to the
Company by such Holder or underwriter and stated to be specifically for use
therein. It is agreed that the indemnity agreement contained in this Section
1.6(a) shall not apply to amounts paid in
 
                                      D-74
<PAGE>   310
 
settlement of any such loss, claim, damage, liability, or action if such
settlement is effected without the consent of the Company (which consent shall
not be unreasonably withheld).
 
     (b) Each Holder will, if Registrable Securities held by him are included in
the securities as to which such registration, qualification, or compliance is
being effected, indemnify the Company, each of its directors, officers,
partners, legal counsel, and accountants and each underwriter, if any, of the
Company's securities covered by such a registration statement, each person who
controls the Company or such underwriter within the meaning of Section 15 of the
Securities Act, each other such Holder and Other Stockholder, and each of their
officers, directors, and partners, and each person controlling such Holder or
Other Stockholder, against all claims, losses, damages and liabilities (or
actions in respect thereof) arising out of or based on any untrue statement (or
alleged untrue statement) of a material fact contained in any such registration
statement, prospectus, offering circular, or other document, or any omission (or
alleged omission) to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, and will reimburse
the Company and such Holders, Other Stockholders, directors, officers, partners,
legal counsel, and accountants, persons, underwriters, or control persons for
any legal or any other expenses reasonably incurred in connection with
investigating or defending any such claim, loss, damage, liability, or action,
in each case to the extent, but only to the extent, that such untrue statement
(or alleged untrue statement) or omission (or alleged omission) is made in such
registration statement, prospectus, offering circular or other document in
reliance upon and in conformity with written information furnished to the
Company by such Holder and stated to be specifically for use therein; provided,
however, that the obligations of such Holder hereunder shall not apply to
amounts paid in settlement of any such claims, losses, damages, or liabilities
(or actions in respect thereof) if such settlement is effected without the
consent of such Holder (which consent shall not be unreasonably withheld) and
(ii) that in no event shall any indemnity under this Section 1.6 exceed the
gross proceeds from the offering received by such Holder.
 
     (c) Each party entitled to indemnification under this Section 1.6 (the
"Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of such claim or any
litigation resulting therefrom, provided that counsel for the Indemnifying
Party, who shall conduct the defense of such claim or any litigation resulting
therefrom, shall be approved by the Indemnified Party (whose approval shall not
unreasonably be withheld), and the Indemnified Party may participate in such
defense at such party's expense, and provided further that the failure of any
Indemnified Party to give notice as provided herein shall not relieve the
Indemnifying Party of its obligations under this Section 1, to the extent such
failure is not prejudicial. No Indemnifying Party, in the defense of any such
claim or litigation, shall, except with the consent of each Indemnified Party,
consent to entry of any judgment or enter into any settlement that does not
include as an unconditional term thereof the giving by the claimant or plaintiff
of a release to such Indemnified Party from all liability in respect to such
claim or litigation. Each Indemnified Party shall furnish such information
regarding itself or the claim in question as an Indemnifying Party may
reasonably request in writing and as shall be reasonably required in connection
with defense of such claim and litigation resulting therefrom.
 
     (d) If the indemnification provided for in this Section 1.6 is held by a
court of competent jurisdiction to be unavailable to an Indemnified Party with
respect to any loss, liability, claim, damage, or expense referred to therein,
then the Indemnifying Party, in lieu of indemnifying such Indemnified Party
hereunder, shall contribute to the amount paid or payable by such Indemnified
Party as a result of such loss, liability, claim, damage, or expense in such
proportion as is appropriate to reflect the relative fault of the Indemnifying
Party on the one hand and of the Indemnified Party on the other in connection
with the conduct, statements or omissions that resulted in such loss, liability,
claim, damage, or expense as well as any other relevant equitable
considerations. The relative fault of the Indemnifying Party and of the
Indemnified Party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission to state a material fact relates to information supplied by the
Indemnifying Party or by the Indemnified Party and the parties' relative intent,
knowledge, access to information, and opportunity to correct or prevent such
statement or omission.
 
                                      D-75
<PAGE>   311
 
     (e) Notwithstanding the foregoing, to the extent that the provisions on
indemnification and contribution contained in the underwriting agreement entered
into by the Indemnifying Party and the Indemnified Party in connection with the
underwritten public offering are in conflict with the foregoing provisions, the
provisions in the underwriting agreement shall control.
 
     1.7 Information by Holder.  Each Holder of Registrable Securities shall
furnish to the Company such information regarding such Holder and the
distribution proposed by such Holder as the Company may reasonably request in
writing and as shall be reasonably required in connection with any registration,
qualification, or compliance referred to in this Section 1.
 
     1.8 Rule 144 Reporting.  With a view to making available the benefits of
certain rules and regulations of the SEC that may permit the sale of the
Restricted Securities to the public without registration, the Company agrees to
use its best efforts to:
 
          (a) make and keep adequate public information regarding the Company
     available as those terms are understood and defined in Rule 144 under the
     Securities Act;
 
          (b) file with the SEC in a timely manner all reports and other
     documents required of the Company under the Securities Act and the Exchange
     Act; and
 
          (c) so long as a Holder owns any Restricted Securities, furnish to the
     Holder forthwith upon written request a written statement by the Company as
     to its compliance with the reporting requirements of Rule 144 and of the
     Securities Act and the Exchange Act, a copy of the most recent annual or
     quarterly report of the Company, and such other reports and documents so
     filed as a Holder may reasonably request in availing itself of any rule or
     regulation of the SEC allowing a Holder to sell any such securities without
     registration.
 
     1.9 Delay of Registration.  No Holder shall have any right to take any
action to restrain, enjoin, or otherwise delay any registration as the result of
any controversy that might arise with respect to the interpretation or
implementation of this Section 1.
 
     1.10 Allocation of Registration Opportunities.  In any circumstance in
which all of the Registrable Securities and other shares of the Company with
registration rights (the "Other Shares") requested to be included in a
registration on behalf of the Holders or Other Stockholders cannot be so
included as a result of limitations of the aggregate number of shares of
Registrable Securities and Other Shares that may be so included, the number of
shares of Registrable Securities and Other Shares that may be so included shall
be allocated among the Holders and Other Stockholders requesting inclusion of
shares pro rata on the basis of the number of shares of Registrable Securities
and Other Shares held by such Holders and Other Stockholders; provided, however,
that such allocation shall not operate to reduce the aggregate number of
Registrable Securities and Other Shares to be included in such registration, if
any Holder or Other Stockholder does not request inclusion of the maximum number
of shares of Registrable Securities and Other Shares allocated to him pursuant
to the above-described procedure, the remaining portion of his allocation shall
be reallocated among those requesting Holders and Other Stockholders whose
allocations did not satisfy their requests pro rata on the basis of the number
of shares of Registrable Securities and Other Shares which would be held by such
Holders and Other Stockholders, assuming conversion, and this procedure shall be
repeated until all of the shares of Registrable Securities and Other Shares
which may be included in the registration on behalf of the Holders and Other
Stockholders have been so allocated.

FOR IMMEDIATE RELEASE
 
     ATLANTA, GEORGIA  -- January 30, 1998 -- WORLD ACCESS, INC. (NASDAQ: WAXS),
announced today that it has completed its acquisition of 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. Pursuant to the terms of a Merger Agreement, the
shareholders of ATI received approximately $10 million worth of World Access
common shares in exchange for their ATI shares and World Access has assumed
approximately $5 million of ATI debt. In addition, the ATI shareholders have the
right to receive additional shares of World Access common stock over the next
two years, contingent upon the achievement of certain pre-tax profitability
levels by ATI.
 
     Steven A. Odom, Chairman and Chief Executive Officer, said "The acquisition
of ATI is in line with the Company's strategy to broaden its offering of
wireless switching, transport and access products and fully support its
customers as they build new and/or upgrade existing telecommunications networks.
ATI is ISO 9001 certified and committed to developing and manufacturing a
complete family of high performance, technologically advanced digital radios for
the global telecommunications markets. ATI's product lines are offered in a wide
range of data rates and frequency bands -- from 1.5 GHz to 38 GHz and DS1/E1 to
DS3/E3. ATI has enjoyed considerable success in recent years in selling its
products to international customers and establishing relationships that
represent significant cross-selling opportunities for other World Access
products and services."
 
     "We are pleased that Dr. Ernie Lin, President of ATI, and his staff of
industry professionals will continue to manage ATI as a division of World
Access. Dr. Lin will report directly to Hatch Graham, President of the Company's
Transport and Access Systems Group. During its latest fiscal year, ATI realized
approximately $15 million in sales. We are optimistic that World Access'
financial strength, extensive U.S. and Latin American telecommunications
customer base, advanced digital switching and wireless transmission products and
broad range of wireless engineering and electronic manufacturing services will
further support ATI's existing business and provide additional sales and profit
growth opportunities for both companies."
 
     World Access, Inc. 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
offers digital switches, cellular base stations, fixed wireless local loop
systems, intelligent multiplexers, digital loop carriers, microwave and
millimeterwave radio equipment and other wireless communications products. To
support and complement its product sales,the Company provides its customers with
a broad range of design, engineering, manufacturing, testing, installation,
repair and other value-added services.

                          INDEPENDENT AUDITOR'S REPORT
 
To the Board of Directors and Stockholders Advanced TechCom, Inc.
Wilmington, Massachusetts
 
     We have audited the accompanying consolidated balance sheet of Advanced
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.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
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.
 
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

     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.

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.

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

     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 L -- CONTINGENCIES
 
     The Company has been 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 has counter
claimed for breach of contract and other causes of action. The Company's
recorded liability at December 31, 1997 was approximately $480,564. 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.

NOTE R -- SUBSEQUENT EVENTS
 
     In December 1997 the Company entered into an Agreement and Plan of Merger
(the "Plan") with World Access, Inc. and its wholly owned Subsidiary, Cellular
Infrastructure Supply, Inc. Under the Plan, the Company's stockholders would
receive shares of World Access, Inc. stock in return for their shares of the
Company's stock. Outstanding stock options were also to be acquired by World
Access, Inc. The final Plan was executed in January 1998.
 
     (b) Pro Forma Financial Information. The acquisition of ATI has been
accounted for using the purchase method of accounting. Immediately subsequent to
such acquisition, World Access recorded a charge of approximately $5.4 million,
representing the portion of the purchase price for ATI allocated to in-process
research and development. World Access has not yet determined the final
allocation of the purchase price, and accordingly, the amount shown below may
differ from the amounts ultimately determined. The following unaudited pro forma
consolidated balance sheet as of December 31, 1997 reflects the acquisition of
ATI as if it had been completed on December 31, 1997. The following unaudited
pro forma consolidated statement of operations for the year ended December 31,
1997 reflect the acquisition of ATI as if it had been completed as of January 1,
1997.
 
     The pro forma data does not purport to be indicative of the results which
would actually have been reported if the acquisition had occurred on such dates
or which may be reported in the future. The pro forma data should be read in
conjunction with the historical consolidated financial statements of the
Company, the historical consolidated financial statements of ATI and the related
notes thereto.

NOTES TO UNAUDITED PRO FORMA CONSOLIDATED BALANCE SHEET
 
     (A) The acquisition of ATI 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 in-process research
and development projects of ATI will be expensed at the consummation of the
acquisition. The amount of the one-time, non-recurring charge is expected to be
approximately $5.4 million. Since this charge is directly related to the
acquisition and will not recurr, the pro forma statements of operations have
been prepared excluding this charge. World Access has not yet determined the
final allocation of the purchase price, and accordingly, the amount shown below
may differ from the amounts ultimately determined.
 
     The unallocated excess of purchase price over net assets acquired is
determined as follows (amounts in thousands):

ITEM 5.  OTHER EVENTS
 
     On December 31, 1997, GST Telecommunications, Inc., a federally chartered
Canadian corporation ("GST"), GST USA, Inc., a Delaware corporation ("GST USA"),
and World Access, Inc. ("World Access") entered into a Stock Purchase Agreement
(the "Purchase Agreement"), pursuant to which World Access has agreed to
purchase from GST USA (hereinafter referred to as the "Acquisition") 5,113,712
shares of the common stock of NACT Telecommunications, Inc. ("NACT") held by GST
USA (hereinafter referred to as the "Shares"), representing approximately 63% of
the outstanding shares of NACT common stock, $.01 par value per share (the "NACT
Common Stock"). Pursuant to the Purchase Agreement, World Access will (i) pay to
GST USA at the Closing (as defined in the Purchase Agreement) cash in the amount
of $59,662,956 by wire transfer of immediately available funds to a United
States bank account designated by GST USA, and (ii) deliver to GST USA at the
Closing shares of the common stock, par value $.01 per share, of World Access
(the "World Access Common Stock") with a Fair Market Value (as defined in the
Purchase Agreement) equal to $29,827,004. The foregoing summary of the
Acquisition is qualified in its entirety by reference to the terms of the
Purchase Agreement and the exhibits thereto, which are attached hereto as
Exhibit 2.1.
 
     On December 31, 1997, World Access also entered into a Stock Agreement with
GST USA, a copy of which is attached as Exhibit D to the Purchase Agreement
("Stock Agreement"), pursuant to which GST USA agreed to vote all voting
securities of NACT held by GST USA in favor of approval of the Purchase
Agreement and the Acquisition and against any merger, consolidation, sale of
assets, reorganization or recapitalization of NACT with any party other than
World Access and its affiliates and against any liquidation or winding up of
NACT.
 
     The Closing will take place as soon as possible after satisfaction of
certain conditions thereto, which include, but are not limited to: (i) the
expiration or termination of the required waiting period under the Hart-
Scott-Rodino Antitrust Improvements Act of 1976, as amended; (ii) the truth and
validity of certain representations and warranties of GST, GST USA and World
Access as of the Closing Date (as defined in the Purchase Agreement); and (iii)
the delivery of certain ancillary documents and agreements contemplated by the
Purchase Agreement. World Access expects to consummate the Acquisition in the
first quarter of 1998.
 
     World Access currently expects to fund the Acquisition through its working
capital.
 
     The following transactions could result in the acquisition by World Access
of additional shares of NACT Common Stock and a change in the present board of
directors of NACT:
 
          (i) Following the Closing, World Access intends promptly to propose a
     merger transaction with NACT pursuant to which all of the outstanding
     shares of NACT Common Stock not owned by World Access would be exchanged
     for shares of World Access Common Stock and NACT would be merged with a
     wholly-owned subsidiary of World Access.
 
          (ii) GST USA has agreed to use its best efforts to obtain the written
     resignation of all of the directors and officers of NACT as World Access
     may specify not less than 10 days prior to the Closing Date, such
     resignations to be effective as of the Closing Date. GST USA has also
     agreed to take all action necessary to cause the board of directors of
     NACT, at and immediately after the Closing, to consist of those directors
     specified by World Access.
 
     The consideration to be paid pursuant to the Purchase Agreement was
determined as a result of negotiations between World Access and GST and the
Acquisition was approved by the boards of directors of World Access, GST and
NACT. Prior to the Acquisition, neither World Access nor any of its affiliates,
directors or officers, nor any associate of any such director or officer, had
any relationship with GST, GST USA or NACT.
 
     Between November 12, 1997 and December 9, 1997, World Access purchased an
aggregate of 350,000 shares of NACT Common Stock in open market purchase
transactions (the "Open Market Purchase"). Accordingly, upon completion of the
Acquisition, World Access will own approximately 68% of the outstanding NACT
Common Stock.

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

                         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

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
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.
 
     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:

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.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  (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 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 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.
 
     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.

     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.

sharing program for full time employees who had completed one full year of

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

     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.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
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

(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 FINANCIAL STATEMENTS
 
1. BASIS OF PRESENTATION
 
     The interim financial statements included herein have been prepared by NACT
Telecommunications, Inc. 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 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 December 31, 1997 and September 30, 1997, and the results of its operations
and cash flows for the three month periods ended December 31, 1997 and 1996. 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 issued Statement
of Financial Accounting Standards No. 128, Earnings per Share (SFAS 128). SFAS
128 established a different method of computing earnings per share than these
same computations under the provisions of Accounting Principles Board Opinion
No. 15. Under SFAS 128, the Company is required to present both basic earnings
per share and diluted earnings per share. SFAS 128 is effective for both interim
and annual periods ending after December 15, 1997. Accordingly, the Company has
adopted SFAS 128 in the first quarter of fiscal 1998.
 
     Basic earnings per share is computed based on the weighted average number
of common shares outstanding during the three month periods ended December 31,
1997 and 1996. Diluted earnings per share for the three month periods ended
December 31, 1997 and 1996 is computed considering the dilutive effect of stock
options, and is not materially different from the basic earnings per share
calculations.
 
3. STOCK PLAN
 
     The Company's 1996 Stock Option Plan (the "Stock Option Plan") was approved
by the Board of Directors and sole stockholder of the Company on November 26,
1996. The purpose of the Stock Option Plan is to create additional incentives
for the Company's employees, directors and others who perform substantial
services to the Company by providing an opportunity to purchase shares of the
Common Stock pursuant to the exercise of options granted under the Stock Option
Plan. The Company may grant options that qualify as incentive stock options
under Section 422 of the Internal Revenue Code, and non-qualified stock options.
Incentive stock options may be granted to employees (including officers and
directors who are employees). Non-qualified stock options may be granted to
employees, officers, directors, independent contractors and consultants of the
Company. As of December 31, 1997, 1,250,000 shares were reserved for issuance
under the Stock Option Plan and options to purchase 1,039,065 shares of Common
Stock were outstanding.
 
     Options become exercisable at such times and in such installments as the
Board of Directors or Compensation Committee provides. The Stock Option Plan
will terminate on November 25, 2006, unless earlier terminated by the Board of
Directors.

     (b) Pro Forma Financial Information. The Acquisition and Open Market
Purchase has been accounted for using the purchase method of accounting. In
connection with the Acquisition, World Access expects to record a charge of
approximately $43.5 million, representing the portion of the purchase price
allocated to in-process research and development. The following unaudited pro
forma consolidated balance sheet as of September 30, 1997 reflects the
Acquisition (together with the Open Market Purchase) as if it had been completed
on September 30, 1997. The following unaudited pro forma consolidated statement
of operations for the year ended December 31, 1996 and the nine months ended
September 30, 1997 reflect the Acquisition (together with the Open Market
Purchase) as if it had been completed as of January 1, 1996.
 
     The pro forma data does not purport to be indicative of the results which
would actually have been reported if the Acquisition (together with the Open
Market Purchase) had occurred on such dates or which may be reported in the
future. The pro forma data should be read in conjunction with the historical
consolidated financial statements of World Access, the historical consolidated
financial statements of NACT, and the related notes thereto.

            NOTES TO UNAUDITED PRO FORMA CONSOLIDATED BALANCE SHEET
 
     (A) Represents the pro forma balance sheet for World Access, Inc. as
presented in the Report on Form 10Q for the Three Months Ended September 30,
1997. The pro forma balance sheet presented above includes the effects of the
sale of $115 million 4.5% convertible subordinated notes which was completed in
October 1997.
 
     (B) Represents the historical balance sheet of NACT Telecommunications,
Inc. as of September 30, 1997.
 
     (C) The Acquisition 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 in-process research
and development projects of NACT will be expensed at the consummation of the
Acquisition. The amount of the one-time non-recurring charge is expected to be
approximately $43.5 million. Since this charge is directly related to the
Acquisition and will not recurring, the pro forma statements of operations have
been prepared excluding this charge. The Company has not yet determined the
final allocation of the purchase price, and accordingly, the amount shown below
may differ from the amounts ultimately determined.
 
     The unallocated excess of purchase price over net assets acquired is
determined as follows (in thousands):

                            STOCK PURCHASE AGREEMENT
 
     THIS AGREEMENT, dated December 31, 1997, is by and among World Access,
Inc., a Delaware corporation ("Buyer"), GST Telecommunications, Inc., a
federally chartered Canadian corporation ("GST"), and GST USA, Inc., a Delaware

                                  WITNESSETH:
 
     WHEREAS, NACT Telecommunications, Inc., a Delaware corporation (the

telecommunications switching platforms with integrated applications software and
network telecommunications capabilities; and
 
     WHEREAS, Seller is a wholly-owned subsidiary of GST and is the record and
beneficial owner of 5,113,712 shares (the "Shares") of the issued and

Company; and
 
     WHEREAS, Buyer desires to purchase from Seller, and Seller desires to sell
to Buyer, the Shares upon the terms and subject to the conditions set forth in
this Agreement;
 
     NOW, THEREFORE, in consideration of the premises and the mutual promises
herein contained, each of Buyer and Seller agrees as follows:
 
                                   ARTICLE I.
                          PURCHASE AND SALE OF SHARES
 
     SECTION 1.1.  Purchase and Sale of Shares.  Upon the terms and subject to
the conditions set forth in this Agreement, on the Closing Date (as hereinafter
defined), Seller shall sell, convey, assign, transfer and deliver to Buyer, and

                                  ARTICLE II.
                REPRESENTATIONS AND WARRANTIES OF SELLER AND GST
 
     Each of Seller and GST represents and warrants to Buyer that:
 
     SECTION 2.1.  Corporate Existence.  Each of Seller, GST and the Company is
a corporation duly organized, validly existing and in good standing under the
laws of its respective jurisdiction of incorporation and has the corporate power
to own, operate or lease its respective properties and to carry on its business
as now being conducted. Complete and correct copies of the Certificate of
Incorporation of the Company and all amendments thereto, certified by the
Secretary of State of the State of Delaware, and of the ByLaws of the Company
and all amendments thereto, certified by the Secretary of the Company,
heretofore have been delivered to Buyer. As a result of the business conducted
by the Company or the character or location of its properties, the Company is
duly qualified to do business and is in good standing in those states listed on
Schedule 2.1 hereto, which states are the only states where the nature of the
business conducted by it or the character or location of its properties requires
such qualification and where the failure to so qualify would have a material
adverse effect upon the business, operations, assets, properties, rights or
condition (financial or otherwise) or prospects of the Company or upon the
ability of the Company to consummate the transactions contemplated by this
Agreement (a "Material Adverse Effect").
 
     SECTION 2.2.  Authorization; Validity.  Each of Seller and GST has all
requisite corporate power and authority to enter into this Agreement, to perform
its respective obligations hereunder and to consummate the transactions
contemplated hereby. Except for the filings by Seller and Buyer required by The
Hart-Scott Rodino Antitrust Improvements Act of 1976, as amended (the "HSR
Act"), no declaration, recording or registration with, or notice to, or
authorization, consent or approval of, any governmental or regulatory body or
authority is necessary for the execution and delivery of this Agreement by
Seller or GST or the consummation by Seller and GST of the transactions
contemplated hereby, other than such declarations, filings, registrations,
notices, authorizations, consents or approvals which, if not made or obtained,
as the case may be, would not, in the aggregate, have a Material Adverse Effect.
All necessary action has been taken by each of Seller and GST with respect to
the execution, delivery and performance by each of Seller and GST of this
Agreement and the consummation of the transactions contemplated hereby. Assuming
the due execution and delivery of this Agreement by Buyer, this Agreement is a
legal, valid and binding obligation of each of Seller and GST, enforceable
against each of Seller and GST in accordance with its terms, subject to
applicable bankruptcy, insolvency, reorganization, moratorium and other similar
laws of general application affecting the enforcement of creditors' rights and
general principles of equity (whether applied in a proceeding at law or in
equity).
 
     SECTION 2.3.  No Breach of Statute or Contract.  Except as set forth on
Schedule 2.3 hereto, neither the execution and delivery of this Agreement, nor
the consummation by each of Seller and GST of the transactions contemplated
hereby, nor compliance by each of Seller and GST with any of the provisions
hereof, will (a) violate or cause a default under any statute (domestic or
foreign), judgment, order, writ, decree, rule or regulation of any court or
governmental authority applicable to Seller, GST or the Company or any of their
respective properties; (b) breach or conflict with any of the terms, provisions
or conditions of the respective Certificates or Articles of Incorporation or
respective By-Laws of Seller, GST or the Company; or (c) violate, conflict with
or breach or require the authorization, consent or approval of any party under
any agreement, contract, mortgage, instrument, indenture or license to which
Seller, GST or the Company is a
                                      E-39
<PAGE>   385
 
party or by which Seller, GST or the Company is or may be bound, or constitute a
default (in and of itself or with the giving of notice, passage of time or both)
thereunder, or result in the creation or imposition of any encumbrance upon, or
give to any other party or parties any claim, interest or right, including
rights of termination or cancellation in, or with respect to, any of their
respective properties or the Shares.
 
     SECTION 2.4.  Subsidiaries.  The Company has no subsidiaries or equity
investments in any other corporation, association, partnership, joint venture or
other entity.
 
     SECTION 2.5.  Ownership of Shares.  Seller is the record and beneficial
owner of the Shares. Seller owns the Shares and the Shares will be transferred
to Buyer, free and clear of all liens, claims, charges and other encumbrances
and restrictions of any kind or nature. Seller has the power, authority and
capacity to transfer and deliver the Shares pursuant to this Agreement and is
not party to or bound by any agreement, arrangement or option restricting in any
manner the sale and transfer of any of the Shares.
 
     SECTION 2.6.  Capitalization; Shares.  The Company's authorized capital
stock consists of 25,000,000 shares of Common Stock, of which 8,128,797 shares
are issued and outstanding on the date hereof and 10,000,000 shares of preferred
stock, $.01 par value per share, none of which are outstanding on the date
hereof. No shares of the Company's capital stock are owned directly or
indirectly by the Company. All of the Company's issued and outstanding shares of
capital stock are duly authorized and validly issued, fully paid and
non-assessable. Except as set forth on Schedule 2.6 hereto, there are no
subscriptions, options, warrants, calls, rights, agreements, commitments,
understandings, restrictions or arrangements of any kind relating to the
issuance, sale or transfer by the Company of any of its capital stock or
relating to the sale or transfer of the Shares, including, without limitation,
any rights of conversion or exchange under any outstanding securities or other
instruments. There are no voting trusts or other agreements or understandings of
any kind with respect to the Shares.
 
     SECTION 2.7.  SEC Reports and Financial Statements.  The Company has timely
filed with the Securities and Exchange Commission (the "SEC"), and has
heretofore made available to Buyer true and complete copies of, all forms,
reports, schedules, statements and other documents required to be filed by it
under the Securities Act of 1933, as amended (the "Securities Act"), and the
Securities Exchange Act of 1934, as amended (the "Exchange Act") (as such
documents have been amended or supplemented since the time of their filing and,
in the case of registration statements and proxy statements, on the dates of
effectiveness and the dates of mailing, respectively, collectively, the "Company
SEC Reports"). At the time of filing, the Company SEC Reports (including any
financial statements or schedules included therein) (a) did not contain any
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading and (b) complied in all
material respects with the applicable requirements of the Securities Act and the
Exchange Act, as the case may be. The audited consolidated financial statements
and unaudited interim consolidated financial statements (including the related
notes) of the Company included in the Company SEC Reports have been prepared in
accordance with generally accepted accounting principles applied on a consistent
basis (except as may be indicated therein or in the notes thereto) and fairly
present in all material respects the financial position of the Company as of the
dates thereof and the results of its operations and changes in financial
position for the periods then ended, subject, in the case of the unaudited
interim financial statements, to normal year-end audit adjustments and any other
adjustments described therein (which will not be material individually or in the
aggregate).
 
     SECTION 2.8.  Absence of Undisclosed Liabilities.  Except as disclosed in
the Company SEC Reports, the Company has no material debts, liabilities or
obligations of any kind, whether accrued, absolute, contingent or other, whether
due or to become due, that would have a Material Adverse Effect.
 
                                      E-40
<PAGE>   386
 
     SECTION 2.9.  Absence of Certain Changes or Events.  Except as set forth on
Schedule 2.9 hereto, since June 30, 1997, no event or circumstance has occurred
resulting or reasonably likely to result in a Material Adverse Effect. Without
limiting the generality of the foregoing, since that date there has not been,
with respect to the Company:
 
          (a) Any change in its Business, operations (as now conducted or as
     presently proposed to be conducted), assets, properties or rights,
     prospects or condition (financial or otherwise), or combination thereof
     which reasonably could be expected to result in a Material Adverse Effect;
 
          (b) Other than in the usual and ordinary course of business, any
     increase in amounts payable by the Company to or for the benefit of or
     committed to be paid by the Company to or for the benefit of any officer,
     director, stockholder, consultant, agent or employee of the Company, in any
     capacity, or in any benefits granted under any bonus, stock option, profit
     sharing, pension, retirement, deferred compensation, insurance, or other
     direct or indirect benefit plan with respect to any such person;
 
          (c) Any transaction entered into or carried out other than in the
     ordinary and usual course of its business, including without limitation,
     any transaction resulting in the incurrence of liabilities or obligations;
 
          (d) Any material change made in the methods of doing business or in
     the accounting principles or practices or the method of application of such
     principles or practices;
 
          (e) Any mortgage, pledge, lien, security interest, hypothecation,
     charge or other encumbrance imposed or agreed to be imposed on or with
     respect to any of its properties that will not be discharged prior to the
     Closing Date except for financing statements filed by personal property
     lessors as a matter of notification only;
 
          (f) Except in the ordinary course of business, any sale, lease or
     other disposition of, or any agreement to sell, lease or otherwise dispose
     of any of its properties, assets or services, individually or in the
     aggregate, in excess of $100,000;
 
          (g) Any purchase of or any agreement to purchase capital assets or any
     lease or any agreement to lease, as lessee, any capital assets,
     individually or in the aggregate, with a purchase price or carrying value
     in excess of $100,000;
 
          (h) Any modification, waiver, change, amendment, release, rescission
     or termination of, or accord and satisfaction with respect to, any material
     term, condition or provision of any contract, agreement, license or other
     instrument to which the Company is a party, other than any satisfaction by
     performance in accordance with the terms thereof in the usual and ordinary
     course of its business;

each trade or business (whether or not incorporated) that together with the
Company is treated as a single employer under Section 414(b), (c), (m) or (o) of
the Internal Revenue Code of 1986, as amended (the "Code").
 
     (c) Except as described in the Company SEC Reports or Schedule 2.16 hereto,
the Company does not maintain, nor has it at any time established or maintained,
nor has it at any time been obligated to make, or otherwise made, contributions
to or under or otherwise participated in any Company Benefit Plan.
 
     (d) Except as described in the Company SEC Reports or on Schedule 2.16
hereto, neither the Company nor any Company ERISA Affiliate maintains, nor has
at any time established or maintained nor has at any time been obligated to
make, or made, contributions to or under any multi-employer plan. Except as
described in the Company SEC Reports or on Schedule 2.16 hereto, the Company

at any time been obligated to make, or made contributions to or under (i) any

employees of the Company; (ii) any organization described in Section 501(s)(9)
or 501(c)(20) of the Code; (iii) any defined benefit pension plan or money

the Company or any Company ERISA Affiliate outstanding pursuant to Section
412(n) of the Code in favor of any Company Benefit Plan. No assets of the
Company or any Company ERISA Affiliate have been provided as security for any
Company Benefit Plan pursuant to Section 401(a)(29) of the Code.
 
     (e) The Company has made available to Buyer a true and complete copy of the
following documents, if applicable, with respect to each Company Benefit Plan
identified in the Company SEC Reports and in Schedule 2.16 hereto; (i) all
documents, including any insurance contracts and trust agreements, setting forth
 
                                      E-44
<PAGE>   390
 
the terms of the Company Benefit Plan, or if there are no such documents
evidencing the Company Benefit Plan, a full description of the Company Benefit
Plan; (ii) the ERISA summary plan description and any other summary of plan
provisions provided to participants or beneficiaries for each such Company
Benefit Plan; (iii) the annual reports filed for the most recent three plan
years and most recent financial statements or periodic accounting of related
plan assets with respect to each Company Benefit Plan; (iv) the more recent
favorable determination letter, opinion or ruling from the Internal Revenue
Service for each Company Benefit Plan, the assets of which are held in trust, to
the effect that such trust is exempt from federal income tax; and (v) each
opinion or ruling from the Department of Labor or the Pension Benefit Guaranty
Corporation with respect to such Company Benefit Plans.
 
     (f) Except as described in Exhibit 2.16 hereto, each Company Benefit Plan
that is funded through a trust or insurance contract has at all times satisfied
in all material respects, by its terms and its operation, all applicable
requirements for an exemption from federal income taxation under Section 501(a)
of the Code. Neither the Company nor any Company ERISA Affiliate maintains a
Company Benefit Plan that meets the requirements of Section 401(a) of the Code
(each a "401 Plan"). Any determination letter issued by the IRS to the effect
that any such 401 Plan qualifies under Section 401(a) of the Code and that the
related trust is exempt from taxation under Section 501(a) of the Code remains
in effect and has not been revoked. Each such 401 Plan, if any, currently
complies in form in all material respects with the requirements under Section
401(a) of the Code, other than changes required by statutes, regulations and
rulings for which amendments are not required. Each 401 Plan, if any, has been
administered in all material respects according to its terms (except for those
terms which are inconsistent with the changes required by statutes, regulations
and rulings) and in accordance with the requirements of Section 401(a) of the
Code. Each such 401 Plan, if any, has been tested for compliance with, and has
satisfied the requirements of, Section 401(k)(3) and (4)(m)(2) of the Code for
each plan year ending prior to the Closing Date.
 
     (g) Except as described in Schedule 2.16 hereto, each Company Benefit Plan
maintained by the Company or a Company ERISA Affiliate has at all times been
maintained, by its terms and in operation, in accordance with all applicable
laws in all material respects, including (to the extent applicable) Code Section
4980B. There has been no failure to comply with applicable ERISA or other
material requirements concerning the filing of reports, documents and notices
with the Secretary of Labor and Secretary of Treasury or the furnishing of such
documents to participants or beneficiaries that could subject any Company
Benefit Plan, the Company or any Company ERISA Affiliate to any material civil
or any criminal sanction.
 
     (h) There are no actions, audits, suits or claims known to Seller that are
pending or threatened against any Company Benefit Plan, any fiduciary of any of
Company Benefit Plans with respect to the Company Benefit Plans, except claims
for benefits made in the ordinary course of the operation of such plans.
 
     (i) The Company and each Company ERISA Affiliate has made full and timely
payment of all amounts required to be contributed under the terms of each
Company Benefit Plan and applicable law or required to be paid as expenses under
such Company Benefit Plan, and no excise taxes are assessable as a result of any
nondeductible or other contributions made or not made to a Company Benefit Plan.
No event or condition exists with respect to any Company Benefit Plan subject to
Title IV of ERISA that could be deemed a "Reportable Event" (as defined in Title
IV or ERISA) with respect to which the 30 day notice requirement has not been
waived that could result in a material liability to Company, and no condition
exists that would subject Company to a material fine under Section 4071 of
ERISA. The assets of all Company Benefit Plans that are required under
applicable laws to be held in trust are in fact held in trust, and the assets of
each such Company Benefit Plan equal or exceed the liabilities of each such
plan. The liabilities of each other plan are properly and accurately reported in
all material respects on the financial statements and records of the Company.
The assets of each Company Benefit Plan are reported at their fair market value
on the books and records of each plan.
 
     (j) Neither the Company nor any Company ERISA Affiliate is subject to any
material liability, tax or penalty whatsoever to any person whomsoever as a
result of Company's or any Company ERISA Affiliate's engaging in a prohibited
transaction under ERISA or the Code, and Seller has no knowledge of any
circumstances that reasonably might result in any such material liability, tax
or penalty as a result of a breach
 
                                      E-45
<PAGE>   391
 
of fiduciary duty under ERISA. The termination of or withdrawal from any Company
Benefit Plan maintained by Company or Company ERISA Affiliate that is subject to
Title IV of ERISA or any other Company Benefit Plan immediately after the
Closing Date will not subject to Company or any Company ERISA Affiliate to any
additional material contribution requirement or to any other material liability,
tax or penalty whatsoever (excluding any liability, tax or penalty attributable
solely to the fact that such termination or withdrawal would violate the
permanency requirement of Section 401(a) of the code or an excise tax under Code
Section 4980). Neither the execution nor the performance of the transactions
contemplated by this Agreement will create, accelerate or increase materially
any obligations under any Company Benefit Plan. Neither the Company nor any
Company ERISA Affiliate has any obligation to any retired or former employee, or
any current employee upon retirement, under any Company Benefit Plan.
 
     (k) From the date of this Agreement to the Closing Date, no amendment shall
be made to any Company Benefit Plan, no commitment shall be made to amend any
Company Benefit Plan and no commitment shall be made to continue any Company
Benefit Plan or to adopt any new Company Benefit Plan for the benefit of any
employees of Company or any Company ERISA Affiliate absent the express written
consent of Buyer.
 
     (l) No payment required to be made to any employee associated with the
Company as a result of the transactions contemplated hereby under any contract
or otherwise will, if made, constitute an "excess parachute payment" within the
meaning of Section 280G of the Code.
 
     (m) Except as described on Schedule 2.16, the consummation of the
transactions contemplated hereby will not accelerate or increase materially
liability under any Company Benefit Plan because of an acceleration or increase
of any of the rights or benefits to which employees of the Company or any
Company ERISA Affiliate may be entitled thereunder.
 
     (n) Except as described on Schedule 2.16, the Company has, on a timely
basis, made all material payments, withholdings and filings of any kind required
of it by, and has otherwise complied in all material respects with, any
applicable law, regulation or administrative order concerning pension, health,
welfare, unemployment, workers' compensation or similar benefits administered by
any governmental, regulatory or public body.
 
     SECTION 2.17.  Brokers.  Except as disclosed on Schedule 2.17, all
negotiations relative to this Agreement and the transactions contemplated hereby
have been carried on by or on behalf of Seller, GST and the Company in such a
manner as not to give rise to any claim against Buyer, any Affiliate (as such
term is defined in the rules and regulations promulgated under the Securities
Act) thereof, Seller, GST or the Company for a finder's fee, brokerage
commission, advisory fee or other similar payment.
 
     SECTION 2.18.  Closing Date Effect.  All of the representations and
warranties of Seller and GST are true and correct as of the date hereof and
shall be true and correct on and as of the Closing Date with the same force and
effect as if such representations and warranties were made by Seller and GST to
Buyer on the Closing Date.
 
                                  ARTICLE III.
 
                    REPRESENTATIONS AND WARRANTIES OF BUYER
 
     Buyer represents and warrants to Seller and GST that:
 
     SECTION 3.1.  Corporate Existence.  Buyer is a corporation duly organized,
validly existing and in good standing under the laws of the State of Delaware.
Complete and correct copies of the Certificate of Incorporation of Buyer and all
amendments thereto, certified by the Secretary of State of the State of
Delaware, and the By-laws of Buyer, and all amendments thereto, certified by the
Secretary of Buyer, heretofore have been delivered to Seller. As a result of the
business conducted by Buyer or the character or location of its properties,
Buyer is duly qualified to do business and is in good standing in those states
listed on Schedule 3.1 hereto, which are the only states where the nature of the
business conducted by it or the character or location of its properties requires
such qualification and where the failure to so qualify would have a material
adverse effect upon the business, operations, assets, properties, rights or
condition (financial or
                                      E-46
<PAGE>   392
 
otherwise) or prospects of Buyer or upon the ability of the Buyer to consummate
the transactions contemplated by this Agreement (a "Buyer Material Adverse
Effect").
 
     SECTION 3.2.  Authorization; Validity.  Buyer has all requisite corporate
power and authority to enter into this Agreement, to perform its obligations
hereunder and to consummate the transactions contemplated hereby. Except for the
filings by Seller and Buyer required by the HSR Act, no declaration, recording
or registration with, or notice to, or authorization, consent or approval of,
any governmental or regulatory body or authority is necessary for the execution
and delivery of this Agreement by Buyer or the consummation by Buyer of the
transactions contemplated hereby, other than such declarations, filings,
registrations, notices, authorizations, consents or approvals which, if not made
or obtained, as the case may be, would not, in the aggregate, have a Buyer
Material Adverse Effect. All necessary corporate action has been taken by Buyer
with respect to the execution, delivery and performance by Buyer of this
Agreement and the consummation of the transactions contemplated hereby. Assuming
the due execution and delivery of this Agreement by Seller and GST, this
Agreement is a legal, valid and binding obligation of Buyer, enforceable against
Buyer in accordance with its terms, subject to applicable bankruptcy,
insolvency, reorganization, moratorium and other similar laws of general
application affecting the enforcement of creditors' rights and general
principles of equity (whether applied in a proceeding at law or in equity).
 
     SECTION 3.3.  No Breach of Statute or Contract.  Neither the execution and
delivery of this Agreement, nor the consummation by Buyer of the transactions
contemplated hereby, nor compliance by Buyer with any of the provisions hereof,
will (a) violate or cause a default under any statute (domestic or foreign),
judgment, order, writ, decree, rule or regulation of any court or governmental
authority applicable to Buyer or any of its material properties; (b) breach or
conflict with any of the terms, provisions or conditions of the Certificate of
Incorporation or By-laws of Buyer; or (c) violate, conflict with or breach or
require the authorization, consent or approval of any party under any agreement,
contract, mortgage, instrument, indenture or license to which Buyer is party or
by which Buyer is or may be bound, or constitute a default (in and of itself or
with the giving of notice, passage of time or both) thereunder, or result in the
creation or imposition of any encumbrance upon, or give to any other party or
parties, any claim, interest or right, including rights of termination or
cancellation in, or with respect to any of Buyer's properties.
 
     SECTION 3.4.  Capitalization; Buyer Common Stock.  Buyer's authorized
capital stock consists of 20,000,000 shares of Buyer Common Stock, of which
19,290,939 shares are issued and outstanding on the date hereof and will be
outstanding on the Closing Date. Except as set forth in Schedule 3.4, there are
no subscriptions, options, warrants, calls, rights, contracts, commitments,
understandings, restrictions or arrangements of any kind relating to the
issuance, sale or transfer by Buyer of its capital stock, including without
limitation, any rights of conversion or exchange under any outstanding
securities or other instruments. The issuance and delivery of the Payment Shares
have been duly and validly authorized by all necessary corporate action on the
part of Buyer and, upon issuance as provided in the Note, will be duly and
validly issued, fully paid and non-assessable. The Payment Shares will be
issued, transferred and delivered to Seller free and clear of any and all liens,
claims, charges, encumbrances, restrictions and agreements of any nature
whatsoever. The Payment Shares will not be issued, transferred, and delivered to
Seller in violation of any preemptive rights, rights of first refusal or other
similar rights.
 
     SECTION 3.5.  SEC Reports and Financial Statements.  Buyer has timely filed
with the SEC, and has heretofore made available to Seller and GST true and
complete copies of, all forms, reports, schedules, statements and other
documents required to be filed by it under the Securities Act and the Exchange
Act on or after January 1, 1995 (as such documents have been amended or
supplemented since the time of their filing and, in the case of registration
statements and proxy statements, on the dates of effectiveness and the dates of
mailing, respectively, collectively, the "Buyer SEC Reports"). At the time of
filing, the Buyer SEC Reports (including any financial statements or schedules
included therein) (a) did not contain any untrue statement of a material fact or
omit to state a material fact required to be stated therein or necessary to make
the statements therein, in light of the circumstances under which they were
made, not misleading and (b) complied in all material respects with the
applicable requirements of the Securities Act and the Exchange Act, as the case
may be. The audited consolidated financial statements and unaudited interim
consolidated financial statements (including the related notes) of Buyer
included in the Buyer SEC Reports have been
                                      E-47
<PAGE>   393
 
prepared in accordance with generally accepted accounting principles applied on
a consistent basis (except as may be indicated therein or in the notes thereto)
and fairly present in all material respects the financial position of Buyer and

threatened against or affecting the Buyer or any of the Buyer's properties or to
Buyer's knowledge any of Buyer's officers or directors in their capacities as
such, in, before or by any Governmental Authority. Seller shall update Schedule
3.8 as of the Closing Date, but any information on such updated schedule
relating to Proceedings arising after the date hereof shall not constitute a
breach of this Section 3.8 unless such Proceedings have had or can reasonably be
expected to have a Buyer Material Adverse Effect. Except as set forth on
Schedule 3.8 or as disclosed in the Buyer SEC Reports, there is no Proceeding
pending or, to the knowledge of Buyer, threatened against or affecting the Buyer

to any Environmental Law and that would result in a Buyer Material Adverse
Effect.
 
     (c) Except as disclosed on Schedule 3.9, there are no Hazardous Substances
that Buyer has used, stored or otherwise held in or on any of the facilities of

its subsidiaries and no agreement with any federal, state, local or foreign tax
authority that may affect the subsequent tax liabilities of the Company; and
 
     (c) Buyer and its subsidiaries have no material liabilities for taxes other

Representatives to treat, all such materials and information in accordance with
the terms and conditions of that certain Mutual Non-Disclosure Agreement dated
December   , 1997 between Buyer and GST (the "Non-Disclosure Agreement").
 
     (b) Buyer shall afford GST and Seller and, on a need to know basis, their
respective accountants, counsel, financial advisors and other representatives

obligations of the respective parties to consummate the transactions
contemplated hereby. Seller and GST shall treat, and shall cause the Seller
Representative to treat, all such materials and information in accordance with
the terms and conditions of the Non-Disclosure Agreement.
 
     SECTION 4.2.  Agreement to Cooperate.
 
     (a) Subject to the terms and conditions herein provided, each of the
parties hereto shall use all reasonable efforts to take, or cause to be taken,
all actions and to do, or cause to be done, all things necessary, proper or
advisable under applicable laws and regulations to consummate and make effective
the transactions contemplated by this Agreement, including using its reasonable
efforts to obtain all necessary or appropriate waivers, consents and approvals
and to effect all necessary filings and submissions.
 
     (b) Without limitation of the foregoing, each of Buyer and Seller
undertakes and agrees to file as soon as practicable after the date hereof a
Notification and Report Form under the HSR Act with the Federal Trade Commission
(the "FTC") and the Antitrust Division of the Department of Justice (the
"Antitrust Division"). Each of Buyer and Seller shall (i) use its best efforts
to comply as expeditiously as possible with
 
                                      E-50
<PAGE>   396
 
all lawful requests of the FTC or the Antitrust Division for additional
information and documents and (ii) not extend any waiting period under the HSR
Act or enter into any agreement with the FTC or the Antitrust Division not to
consummate the transactions contemplated by this Agreement, except with the
prior consent of the other parties hereto.
 
     SECTION 4.3.  Directors' and Officers' Indemnification.
 
     (a) Subject to the terms of this Section 4.3, after the Closing Date and
notwithstanding any other provision contained in this Agreement, Buyer shall and
shall cause the Company, to the fullest extent permitted under applicable law,
to jointly and severally indemnify and hold harmless, each director, officer,
employee and agent of the Company who served as such at any time prior to the
Closing Date (each, together with such person's heirs, executors or
administrators, an "NACT Indemnified Party" and collectively, the "NACT
Indemnified Parties") against any costs or expenses (including attorneys' fees),
judgments, fines, losses, claims, damages, liabilities and amounts paid in
settlement in connection with any claim, action, suit, proceeding or
investigation, whether civil, criminal, administrative or investigative (each an
"NACT Claim"), arising out of, relating to or in connection with any action or
omission occurring prior to the Closing Date (including, without limitation,
acts or omissions in connection with such persons serving as an officer,
director or other fiduciary in any entity if such service was at the request or
for the benefit of the Company) or arising out of or pertaining to the
transactions contemplated by this Agreement; provided, however, that Buyer shall
have no obligation to indemnify any of the NACT Indemnified Parties hereunder
unless such party acted in good faith and in a manner he reasonably believed to
be in or not opposed to the best interests of the Company, and, with respect to
any criminal action or proceeding, had no reasonable cause to believe his
conduct was unlawful (the "Conduct Standard").
 
     (b) If any NACT Indemnified Party shall seek indemnification pursuant to
Section 4.3(a), such NACT Indemnified Party shall give prompt notice to Buyer of
an NACT Claim within 10 days after receipt by the NACT Indemnified Party of
notice of any such NACT Claim; provided, however, that the failure to provide
such notice shall not release Buyer or the Company from any of their respective
obligations under this Section 4.3, except to the extent that Buyer or the
Company is materially prejudiced by such failure. The obligations and
liabilities of Buyer and the Company under this Section 4.3 shall be governed by
and contingent upon the following additional terms and conditions: Upon receipt
of notice from an NACT Indemnified Party as provided in this Section 4.3(b),
Buyer shall be entitled to assume and control the defense of the NACT Claim
identified in such notice at its expense and through counsel of its choice
reasonably satisfactory to such NACT Indemnified Party, if it gives notice of
its intention to do so to such NACT Indemnified Party within 10 days after the
receipt of such notice from such NACT Indemnified Party and actually assumes and
controls such defense. The NACT Indemnified Party may, at its election and at
its sole cost and expense, participate in any such defense. Notwithstanding the
foregoing, if there exists a conflict of interest that would make it
inappropriate for the same counsel to represent both the Indemnified Party, on
the one hand, and the Indemnifying Party, on the other hand, in connection with
any Indemnifiable Claim, then the Indemnified Party shall be entitled to retain
its own counsel as is reasonably satisfactory to the Indemnifying Party at the
Indemnifying Party's expense. In the event that such Indemnified Party shall
seek indemnification as provided herein, such Indemnified Party shall make
available to the Indemnifying Party, at its expense, all witnesses, pertinent
records, materials and information in the Indemnified Party's possession or
under the Indemnified Party's control relating thereto as is reasonably required
by the Indemnifying Party.
 
     (c) Any determination required to be made with respect to whether an NACT
Indemnified Party's conduct satisfies the Conduct Standard shall be made by
independent legal counsel acceptable to Buyer, the Company and the NACT
Indemnified Party.
 
     (d) In the event Buyer or the Company or any of their successors or assigns
(i) consolidates with or merges into any other person and shall not be the
continuing or surviving corporation or entity of such consolidation or merger or
(ii) transfers all or substantially all of its properties and assets to any
person, then and in each such case, proper provisions shall be made so that the
successors and assigns of the Buyer or the Company, as the case may be, shall
assume the obligations set forth in this Section 4.3.

     properties or services or cancel or agree to cancel any debt or claim,
     except in each case in the ordinary course of business;
 
          (v) consent or agree to a waiver of any right of substantial value;

     in the ordinary course of business consistent with past practice;
 
          (xii) introduce any new method of management, operation or accounting

     applicable thereto;
 
          (xiii) offer or extend more favorable prices, discounts or allowances
     than were offered or extended regularly on and prior to the date hereof;
 
          (xiv) make capital expenditures or commitments therefor in excess of
     $100,000 except for repairs and maintenance in the ordinary course of

     SECTION 4.5.  Conduct of Buyer's Business Prior to the Closing Date.  Buyer
agrees that, between the date of this Agreement and the Closing Date, except (a)
for any actions taken by Buyer relating to any other acquisitions or business

Agreement, unless Seller shall otherwise agree in writing, (x) the respective
business of Buyer and its subsidiaries shall be conducted only in, and shall not
take any action except in, the ordinary course of business consistent with past
practice. By way of amplification and not limitation, except (a) for any actions
taken by Buyer relating to any other acquisitions or business combinations or
(b) as expressly contemplated by any other provision of this Agreement, neither
Buyer nor its subsidiaries shall, between the date of this Agreement and the
Closing Date, directly or indirectly, do, or agree to do, any of the following
without the prior written consent of Seller, which consent shall not be
unreasonably withheld or delayed:
 
          (i) declare, set aside, make or pay any dividend or other
     distribution, payable in cash, stock, property or otherwise, with respect

through tender or exchange offer, merger or otherwise, all of the outstanding
Common Stock not then owned by it (the "Minority Interest") for a per share
purchase price of not less than $17.50, payable in Buyer Common Stock, cash or a
combination thereof. Not later than the time Buyer consummates any such
transaction, it shall obtain (or shall cause the Company to obtain) a written
opinion from a nationally recognized investment banking firm as to the fairness
from a financial point of view of the consideration to be received by the
holders of Common Stock in such transaction. Notwithstanding the foregoing,
Buyer may elect not to acquire the Minority Interest, in which event, during
such 180 day period, provided Seller has exercised the Seller Option, Buyer
shall offer in writing to acquire the remaining shares of Common Stock owned by
Seller for a per share price of not less than $17.50, payable in Buyer Common
Stock, cash or a combination thereof. Within 15 days after receipt of such
offer, Seller shall advise Buyer in writing whether or not it accepts Buyer's
offer, which acceptance will be solely within Seller's discretion. In the event
that Seller exercises the Seller Option, the shares of Buyer Common Stock to be
received by Seller upon acquisition by Buyer of the Minority Interest or upon
acceptance by Seller of Buyer's offer shall be registered in the name of Seller
and/or its designee, any such designation to be made in writing by Seller, and
Seller and/or such designee shall hold and dispose of such shares of Buyer
Common Stock on substantially the same terms and conditions as those provided in
the Registration Rights Agreement (as hereinafter defined). Seller and Buyer
shall execute an agreement containing such terms and conditions at or before the
time of Buyer's acquisition of the Common Stock owned by Seller.
 
     SECTION 4.7.  Announcements.  None of the parties to this Agreement nor any
of their respective Affiliates shall make any public announcements prior to the
Closing Date or any time thereafter with respect to this Agreement or the
transactions contemplated hereby without the written consent of the other
parties hereto, unless advised by counsel that such disclosure is required by
law (in which event such party shall promptly notify the other parties hereto).
 
     SECTION 4.8.  Exemption from Anti-Takeover Statutes.  Each of Seller and

steps required to exempt the transactions contemplated by this Agreement from
any applicable state anti-takeover law, including, without limitation, Section
203 of the General Corporate Law of the State of Delaware.
 
     SECTION 4.9.  Resignations.  Seller (a) shall use its best efforts to
obtain the written resignation of all directors and officers of the Company as
Buyer may specify to Seller in writing not less than 10 days prior
                                      E-53
<PAGE>   399
 
to the Closing Date, effective as of the Closing Date, and (b) shall take all
action necessary to cause the Board of Directors of the Company, at and
immediately after the Closing, to consist of those directors specified by Buyer
in writing not less than 10 days prior to Closing.
 
     SECTION 4.10.  Compliance with Rule 14f-1.  Seller shall cause the Company
to comply on a timely basis with Rule 14f-1 promulgated under the Exchange Act.
Buyer shall cooperate in effecting such compliance and shall supply the Company
with all information concerning it and its designees on the Board of Directors
of the Company required to be presented in accordance with such rule.
 
     SECTION 4.11.  Satisfaction of Conditions.  Each of the parties hereto
shall use its best efforts to fulfill or obtain the fulfillment of all of the
conditions to Closing.
 
     SECTION 4.12.  Notice of Developments.  Buyer, GST and Seller agree to give
each other prompt written notice in the event its own representations and
warranties are discovered to be untrue as of the time made or in the event such
party determines that such representations and warranties shall be untrue as if
made at and as the Closing Date. No disclosure by Buyer, GST or Seller pursuant
to this Section 4.12, however, shall be deemed to or shall supplement the
schedules hereto or to cure any misrepresentation or breach of warranty;
provided, however, that the delivery of or failure to deliver any notice
pursuant to this Section 4.12 shall not limit or otherwise affect the remedies
available hereunder to the party receiving such notice.

                                  ARTICLE VII.
 
                      INDEMNIFICATION; AEROTEL LITIGATION
 
     SECTION 7.1.  Survival of Covenants and Agreements.  Each of the covenants
and agreements contained in this Agreement and in each of the documents and
instruments referred to herein that is intended by its terms to be performed in
whole or in part subsequent to the Closing Date shall survive the execution and
delivery of this Agreement and the Closing.
 
     SECTION 7.2.  Survival of Representations and Warranties.  Except as
hereinafter provided, none of the representations and warranties contained
herein shall survive the Closing and from and after the Closing Date, no party
hereto or any Affiliate of such party shall have any liability or obligation in
respect thereof. Notwithstanding the foregoing, (a) the representations and
warranties contained in Sections 2.14 and 3.10 hereof shall survive the Closing
until the expiration of the periods of limitations and any extensions thereof
under applicable federal, state and local laws, rules and regulations applicable
to assessment and collection of the tax or taxes to which any such
representation or warranty relates; (b) the representations and warranties
contained in Sections 2.2, 2.5 and 3.2 hereof shall survive until the fifth
anniversary of the Closing Date.
 
     SECTION 7.3. Indemnification.
 
     (a) Subject to the limitations set forth in this Article VII, GST and
Seller jointly and severally indemnify and hold harmless Buyer from and against
any and all losses, liabilities, damages, demands, claims, suits, actions,
judgments or causes of action, assessments, costs and expenses including,
without limitation, interest, penalties, reasonable attorneys' fees, any and all
reasonable expenses incurred in investigating, preparing or defending against
any litigation, commenced or threatened, or any claim whatsoever, and any and
all amounts paid in settlement of any claim or litigation (collectively,
"Damages"), asserted against, resulting to, imposed upon, or incurred or
suffered by Buyer, directly or indirectly, as a result of or arising from any
inaccuracy in or breach of the representations and warranties made in Sections
2.2, 2.5 and 2.14 of this Agreement (individually an "Indemnifiable Claim" and
collectively "Indemnifiable Claims" when used in the context of Buyer as the
Indemnified Party (as hereinafter defined)).
 
     (b) Subject to the limitations set forth in this Article VII, Buyer shall
indemnify and hold harmless each of GST and Seller from and against any and all
Damages asserted against, resulting to, imposed upon, or incurred or suffered by
GST or Seller, directly or indirectly, as a result of or arising from any
inaccuracy in or breach of any of the representations and warranties made by
Buyer in Sections 3.2 and 3.10 of this Agreement (individually an "Indemnifiable
Claim" and collectively "Indemnifiable Claims" when used in the context of GST
or Seller as the Indemnified Party).
 
     (c) For purposes of this Article VII, all Damages shall be computed net of
any insurance coverage (from the amount of which coverage there shall be
deducted all costs and expenses, including attorneys' fees, of the Indemnified
Party not reimbursed by such coverage) with respect thereto that reduces the
Damages that would otherwise be sustained; provided, however, that in all cases,
the timing of the receipt or realization of insurance proceeds shall be taken
into account in determining the amount of reduction of Damages.
 
     SECTION 7.4.  Limitations on Indemnification.  Rights to indemnification
hereunder are subject to the following limitations:
 
          (a) The obligation of indemnity in respect of (i) Sections 2.14 and
     3.10 hereof shall terminate on the expiration of the periods of limitations
     and any extensions thereof under federal, state and local laws, rules and
     regulations applicable to assessment and collection of the tax or taxes
     with respect to which indemnification is sought; and (ii) Sections 2.2, 2.5
     and 3.2 hereof shall terminate on the fifth anniversary of the Closing
     Date.
 
          (b) If, prior to the termination of any obligation to indemnify as
     provided for herein, written notice of a claimed breach is given by the
     party seeking indemnification including in detail the basis therefor (the
     "Indemnified Party") to the party from whom indemnification is sought (the
     "Indemnifying Party")
 
                                      E-57
<PAGE>   403
 
     or a suit or action based upon a claimed breach is commenced against the
     Indemnified Party, the Indemnified Party shall not be precluded from
     pursuing such claimed breach or suit or action, or from recovering from the
     Indemnifying Party (whether through the courts or otherwise) on the claim,
     suit or action, by reason of the termination otherwise provided for above.
 
          (c) The right of any party hereto to commence or assert an action,
     suit, claim or proceeding for Damages in respect of the breach of a
     representation or warranty contained herein shall terminate at the same
     time that the obligation of indemnification provided herein with respect to
     such breach shall terminate.
 
     SECTION 7.5.  Procedure for Indemnification with Respect to Third-Party
Claims.  The Indemnified Party shall give the Indemnifying Party prompt written
notice of any third party claim, demand, assessment, suit or proceeding to which
the indemnification set forth in Section 7.3 applies, which notice to be
effective must describe such claim in reasonable detail (the "Indemnification
Notice"). Notwithstanding the foregoing, the Indemnified Party shall not have
any obligation to give any notice of any assertion of liability by a third party
unless such assertion is in writing, and the rights of the Indemnified Party to
be indemnified hereunder in respect of any third party claim shall not be
adversely affected by its failure to give notice pursuant to the foregoing
unless and, if so, only to the extent that, the Indemnifying Party is materially
prejudiced thereby. The Indemnifying Party shall have the right to control the
defense or settlement of any such action subject to the provisions set forth
below, but the Indemnified Party may, at its election, participate in the
defense of any action or proceeding at its sole cost and expense.
Notwithstanding the foregoing, if there exists a conflict of interest that would
make it inappropriate for the same counsel to represent both the Indemnified
Party, on the one hand, and the Indemnifying Party, on the other hand, in
connection with any Indemnifiable Claim, then the Indemnified Party shall be
entitled to retain its own counsel as is reasonably satisfactory to the
Indemnifying Party at the Indemnifying Party's expense. In the event that such
Indemnified Party shall seek indemnification as provided herein, such
Indemnified Party shall make available to the Indemnifying Party, at its
expense, all witnesses, pertinent records, materials and information in the
Indemnified Party's possession or under the Indemnified Party's control relating
thereto as is reasonably required by the Indemnifying Party. Should the
Indemnifying Party fail to defend any such Indemnifiable Claim (except for
failure resulting from the Indemnified Party's failure to timely give notice of
such Indemnifiable claim), then, in addition to any other remedy, the
Indemnified Party may settle or defend such action or proceeding through counsel
of its own choosing and may recover from the Indemnifying Party the amount of
such settlement, demand, or any judgment or decree and all of its costs and
expenses, including reasonable fees and disbursements of counsel. Except as
permitted in the preceding sentence, the Indemnifying Party shall not be liable
for any settlement effected without its written consent, which consent shall not
be unreasonably withheld; provided, however, if such approval is unreasonably
withheld, the liability of the Indemnifying Party shall be limited to the amount
of the proposed compromise or settlement and the amount of the Indemnified
Party's reasonable counsel fees incurred in defending such claim, as permitted
by the preceding sentence, at the time such consent is unreasonably withheld.
Notwithstanding the preceding sentence, the right of the Indemnified Party to
compromise or settle any claim without the prior written consent of the
Indemnifying Party shall only be available if a complete release of the
Indemnifying Party is contemplated to be part of the proposed compromise or
settlement of such third party claim.
 
     SECTION 7.6.  Procedure For Indemnification with Respect to Non-Third-Party
Claims.  In the event that the Indemnified Party asserts the existence of an
Indemnifiable Claim (but excluding claims resulting from the assertion of
liability by third parties), it shall give prompt written notice to the
Indemnifying Party specifying the nature and amount of the claim asserted (the
"Non-Third Party Claim Indemnification Notice"). If the Indemnifying Party,
within 30 days (or such greater time as may be necessary for the Indemnifying
Party to investigate such Indemnifiable Claim not to exceed 60 days), after
receiving the Non-Third Party Claim Indemnification Notice from the Indemnified
Party, shall not give written notice to the Indemnified Party announcing its
intent to contest such assertion of the Indemnified Party (the "Contest
Notice"), such assertion shall be deemed accepted and the amount of the claim
shall be deemed a valid Indemnifiable Claim. During the time period set forth in
the preceding sentence, the Indemnified Party shall cooperate fully with the
Indemnifying Party in respect of such Indemnifiable Claim. In the event,
however,
 
                                      E-58
<PAGE>   404
 
that the Indemnifying Party contests the assertion of a claim by giving a
Contest Notice to the Indemnified Party within such period, then if the parties
hereto, acting in good faith, cannot reach agreement with respect to such claim
within 60 days after such notice was first given to the Indemnifying Party, such
parties may seek any remedy available to them at law or in equity.
 
     SECTION 7.7.  Aerotel Litigation.  GST, Seller, the Company and others are
parties to the action identified as item 1 in Schedule 2.11 hereto (the "Aerotel
Litigation"). Notwithstanding anything herein to the contrary, the following
provisions shall be applicable with respect to the Aerotel Litigation from and
after the Closing Date:
 
          (a) The firm of Madson & Metcalf ("M&M"), currently counsel to NACT,
     shall also become counsel to GST and Seller in the Aerotel Litigation. So
     long as the Aerotel Litigation is pending, each of the Company, GST and
     Seller shall waive any and all conflicts that may arise in the course of
     the representation of each, so that each may continue to be represented by
     M&M therein. In connection with the Aerotel Litigation, each of (i) the
     Company and (ii) GST and Seller (jointly and severally) shall be
     responsible for 50% of all of the reasonable attorneys' fees and expenses
     of M&M in its representation of the Company, and M&M shall bill the Company
     (on the one hand) and GST and Seller (on the other hand) for such fees and
     expenses in accordance therewith.
 
          (b) The aggregate Aerotel Damages (as hereinafter defined) shall be
     borne by the parties hereto in the following proportions: the
     Company -- 50%; and GST and Seller jointly and severally -- 50%.
     Notwithstanding anything to the contrary, the Company shall not be
     responsible for any fees or expenses of any counsel to either GST or Seller
     in connection with the Aerotel Litigation.
 
          (c) For the purposes hereof, "Aerotel Damages" shall mean the
     following required to be paid by the Company relating to the Aerotel
     Litigation: (i) reasonable attorneys' fees (including those incurred in the
     representation of Thomas E. Sawyer and Kyle B. Love by separate counsel)
     incurred in defending any claim or prosecuting any defense or counterclaim
     asserted in the Aerotel Litigation, including any and all appeals; (ii) in
     respect of all periods ending on or before the Determination Date (as
     hereinafter defined), all losses, liabilities, damages, demands, claims,
     suits, actions, judgments, causes of action, assessments, costs and
     expenses, including without limitation, interest, penalties, royalties,
     license fees, any and all reasonable expenses incurred in investigating,
     preparing or defending the Aerotel Litigation and amounts paid in
     settlement thereof; and (iii) in respect of the Post Determination Date
     Period (as hereinafter defined), (A) all royalties or license fees that are
     required to be paid pursuant to a license or royalty agreement entered into
     on a good faith basis subsequent to the Determination Date by the Company
     on behalf of itself and on behalf of purchasers of its products (to the
     extent not directly or indirectly passed on to such purchasers) for the use
     of intellectual property at issue in the Aerotel Litigation; (B) refunds
     required to be made to such purchasers pursuant to written agreements with
     such purchasers as a result of the Aerotel Litigation; and (C) costs of
     replacement or modification of products sold to such purchasers required to
     be made as a direct result of the Aerotel Litigation; provided, that in no
     event shall the proportion of Aerotel Damages in respect to the Post
     Determination Date Period to be borne by GST and Seller jointly exceed
     $2,000,000 in aggregate amount. Anything in the foregoing to the contrary
     notwithstanding, Aerotel Damages shall not include (i) the Company's
     internal costs, including without limitation those of the Company's
     personnel in assisting counsel and in preparing for pre-trial discovery and
     trial and in post-trial matters, and the Company's direct expenses in
     assisting counsel, including without limitation, photocopying,
     telecommunications and transportation costs; (ii) the fees of more than two
     law firms representing the Company, and in such connection, the parties
     hereto agree that the two law firms representing the Company shall be M&M
     and the law firm substituted for Olshan Grundman Frome & Rosenzweig LLP, as
     New York counsel in the Aerotel Litigation; (iii) the fees of any law firm
     that may hereafter represent Buyer; (iv) any claim or theory of damages
     based upon diminution or alleged diminution in value of the Company as an
     enterprise as a result of any adjudication or settlement of the Aerotel
     Litigation; or (v) losses, liabilities, damages, demands, claims, suits,
     actions, judgments, causes of action, assessments, costs and expenses,
     including without limitation, interest, penalties, attorneys' fees, or any
     and all expenses required to be paid by the Company in respect of periods
     commencing subsequent to the Post Determination Date Period. For the
     purposes hereof,
                                      E-59
<PAGE>   405
 
     "Determination Date" shall mean the date on which a judgment is issued by
     the District Court in the Aerotel Litigation, which judgment includes an
     adjudication that Aerotel's patent is valid and that it has been infringed.
     Within 15 days after the Determination Date, GST shall give written notice
     to Buyer whether GST desires that an appeal be taken from the judgment of
     the District Court. Within 15 days after such notice is given, Buyer shall
     give written notice of its determination whether to take such appeal. If
     Buyer determines not to take such appeal, or if Buyer determines to take
     such appeal and GST has notified Buyer that it desires that such appeal not
     be taken, then the Post Determination Date Period shall be the period
     commencing on the Determination Date and ending on the day preceding the
     first anniversary thereof. If Buyer determines to take such appeal and GST
     has notified Buyer that it desires that such appeal be taken, then the Post
     Determination Date Period shall be the period commencing on the
     Determination Date and ending on the day preceding the second anniversary
     thereof.
 
          (d) Within 30 days after the end of each calendar quarter, commencing
     with the calendar quarter in which the Closing Date occurs, Buyer shall
     give to Seller and Seller shall give to Buyer written notice (the "Aerotel
     Damages Notice") of the amount of Aerotel Damages paid by it during such
     calendar quarter, providing reasonable detail of such Aerotel Damages and
     accompanying such Aerotel Damages Notice with supporting invoices and
     vouchers. If, within 30 days after receiving an Aerotel Damages Notice, the
     recipient shall not give written notice to the other party announcing its
     intent to contest such Aerotel Damages Notice (the "Aerotel Contest
     Notice"), such Aerotel Damages Notice shall be deemed accepted. In such
     event, the parties shall make appropriate payments to one another so that
     the Aerotel Damages for such calendar quarter shall be borne by them in the
     relative proportions set forth in Section 7.7(b). During the time period
     set forth in the preceding sentence, the parties shall cooperate fully in
     respect of such Aerotel Damages Notice. In the event, however, that a party
     contests the Aerotel Damages Notice by giving an Aerotel Contest Notice to
     the other party within such period, then if the parties, acting in good
     faith, cannot reach agreement with respect to such contest within 60 days
     after the Aerotel Contest Notice was first given, the provisions of Section
     7.7(g) shall be applicable.
 
          (e) In the event that GST and Seller cease to be parties in the
     Aerotel Litigation and the Company remains a defendant, including a
     defendant-appellant therein, Buyer shall cause the Company to keep GST
     fully informed at all times as to the status of the Aerotel Litigation. It
     shall cause the Company to provide GST with a copy of all material
     documents proposed to be filed therein not less than five days prior to
     such proposed filing and the Company will give due consideration to any
     comment of GST with respect thereto. If for any reason (other than
     settlement as contemplated below) the Company fails or refuses to maintain
     the defense of the Aerotel Litigation or to pursue the immediate appeal of
     any adverse ruling therein, GST shall have the right in the name of the
     Company to assume such defense or to perfect such appeal in such manner as
     it deems appropriate.
 
          (f) After the Closing, Buyer shall not and shall cause the Company not
     to, settle or compromise the Aerotel Litigation on behalf of the Company,
     without the express written consent of each of the parties to this
     Agreement, which consent shall not be unreasonably withheld or delayed.
     Prior to the Closing, GST shall not, and shall cause the Company not to,
     settle or compromise the Aerotel Litigation on behalf of the Company,
     without the express written consent of each of the parties to this
     Agreement, which consent shall not be unreasonably withheld or delayed.
 
          (g) Any dispute arising out of this Section 7.7 shall be submitted to
     and settled by arbitration in accordance with the commercial arbitration
     rules of the American Arbitration Association then in effect. Such
     arbitration shall be held in Washington, D.C. before a panel of three
     arbitrators, one selected by each of the parties and the third selected by
     mutual agreement of the first two, and all of whom shall be independent and
     impartial under the rules of the American Arbitration Association. The
     decision of the arbitrators shall be final and binding as to any matter
     submitted under this Agreement. To the extent the decision of the
     arbitrators is that a party shall be indemnified hereunder, the amount
     shall be satisfied as herein provided. Judgment upon any award rendered by
     the arbitrators may be entered in any court of competent jurisdiction.
 
                                      E-60
<PAGE>   406
 
     SECTION 7.8.  Payment.  In the event that any party is required to make any
payment under this Article VII, such party shall promptly pay the other party
the amount so determined. If there should be a dispute as to the amount or
manner of determination of any indemnity obligation owed under this Article VII,
the paying party shall nevertheless pay when due such portion, if any, of the
obligation as shall not be subject to dispute. The difference, if any, between
the amount of the obligation ultimately determined as properly payable under
this Article VII and the portion, if any, theretofore paid shall bear interest
as provided below. If all or part of any indemnification obligation under this
Agreement is not paid when due, then the paying party shall pay the other party

interest generally charged from time to time by Morgan Guaranty Trust Company of
New York and publicly announced by such bank as its so-called "prime rate" plus
(ii) five percent (5%).

but in any event on or prior to the date 60 days following the date hereof (the
"Filing Date"), a Registration Statement for an offering to be made on a
continuous basis pursuant to Rule 415 of the Securities Act (a "Shelf
Registration") registering the resale from time to time by the Holders thereof
of all of the Registrable Securities (the "Initial Shelf Registration"). The
Initial Shelf Registration shall be on an appropriate SEC Registration Statement
form permitting registration of such Registrable Securities for resale by such
Holders in the manner or manners designated thereby (including, without
limitation, one or more Underwritten Offerings). The Company shall use its best
efforts to cause the Initial Shelf Registration to be declared effective under
the Securities Act as
                                      E-66
<PAGE>   412
 
soon as practicable but in any event on or prior to the date 180 days following
the date hereof (the "Effectiveness Target Date"), and shall use its best
efforts to keep the Initial Shelf Registration continuously effective under the
Securities Act, subject to the provisions of Section 2(c), until the earlier of
the expiration of the Effectiveness Period or the date a Subsequent Shelf
Registration (as defined below) covering all of the Registrable Securities has
been declared effective under the Securities Act. Subject to the right of the
Company to have the Initial Shelf Registration not be effective, or not to be
updated, amended or supplemented, for periods of time set forth in Section 2(c),
the Company further agrees to use its best efforts to prevent the happening of
any event that would cause the Initial Shelf Registration to contain a material
misstatement or omission or to be not effective and usable for resale of the
Registrable Securities during the Effective Period.
 
     (b) If the Initial Shelf Registration or any Subsequent Shelf Registration
ceases to be effective for any reason as a result of the issuance of a stop
order by the SEC at any time during the Effectiveness Period, the Company shall
use its best efforts to obtain the prompt withdrawal of any order suspending the
effectiveness thereof, and in any event shall within 15 days of such cessation
of effectiveness amend the Shelf Registration in a manner reasonably expected to
obtain the withdrawal of the order suspending the effectiveness thereof, or file
an additional Shelf Registration covering all of the Registrable Securities (a
"Subsequent Shelf Registration"). If a Subsequent Shelf Registration is filed,
the Company shall use its best efforts to cause the Subsequent Shelf
Registration to be declared effective as soon as practicable after such filing
and to keep such Registration Statement continuously effective until the end of
the Effectiveness Period.
 
     (c) In the event (A) of the happening of any event of the kind described in
Section 3(c)(ii), 3(c)(iii), 3(c)(iv), 3(c)(v) or 3(c)(vi) hereof or (B) that,
in the good faith-judgment of the Company, it is advisable to suspend the use of
the Prospectus for a discrete period of time due to pending material corporate
developments or similar material events that have not yet been publicly
disclosed and as to which the Company believes public disclosure will be
prejudicial to the Company, the Company shall deliver a certificate in writing,
signed by an authorized executive officer of the Company, to the Holders and the
Managing Underwriters, if any, to the effect of the foregoing and thereafter the
use of the Prospectus shall be suspended, and the Company, subject to the terms
of this Section 2(c), shall thereafter not be required to maintain the
effectiveness or update the Shelf Registration. The Company will use its best
efforts to ensure that the use of the Prospectus may be resumed as soon as
practicable, in the case of suspension under Section 2(c)(A), and, in the case
of a pending development or event referred to in Section 2(c)(B) hereof, as soon
as, in the good faith-judgment of the Company, public disclosure of such
material corporate development or similar material event would not have a
material adverse effect on the Company. Notwithstanding the foregoing, the
Company shall not under any circumstances be entitled to exercise its right
under this Section 2(c) to suspend the use of the Prospectus (whether as a
result of events referred to in Section 2(c)(A) hereof or as a result of the
pending development or event referred to in Section 2(c)(B) hereof) more than
one (1) time in any three (3) month period, and the periods in which the use of
the Prospectus is suspended shall not exceed 15 days in any three-month period
(a "Suspension Period").
 
3. REGISTRATION PROCEDURES.
 
     In connection with the Company's registration obligations under Section 2
hereof, the Company shall effect such registrations to permit the sale of the
Registrable Securities in accordance with the intended method or methods of
disposition thereof, and pursuant thereto the Company shall as expeditiously as
possible:
 
          (a) Prepare and file with the SEC a Registration Statement or
     Registration Statements on any appropriate form under the Securities Act
     available for the sale of the Registrable Securities by the Holders in
     accordance with the intended method or methods of distribution thereof and
     shall include all required financial statements, and use its best efforts
     to cause each such Registration Statement to become effective and remain
     effective as provided herein; provided that before filing any such
     Registration Statement or Prospectus or any amendments or supplements
     thereto the Company shall furnish within a reasonable time period to each
     Selling Holder (if requested by such Selling Holder) and
 
                                      E-67
<PAGE>   413
 
     the Managing Underwriters of such offering, if any, copies of all such
     documents proposed to be filed, which documents will be subject to the
     review of such Selling Holders (if requested by such Selling Holders) and
     such Managing Underwriters, and the Company shall not file any such
     Registration Statement or amendment thereto or any Prospectus or any
     supplement thereto to which such Selling Holders shall reasonably object in
     writing within five Business Days after the receipt thereof. In addition,
     the Company shall use its best efforts to reflect in each such document
     referenced in this paragraph so filed with the SEC such comments as each
     Selling Holder and the Managing Underwriters, if any, may propose.
 
          (b) Subject to Section 2(c), prepare and file with the SEC such
     amendments and post-effective amendments to each Registration Statement as
     may be necessary to keep such Registration Statement continuously effective
     for the applicable period specified in Section 2; cause the related
     Prospectus to be supplemented by any required Prospectus supplement, and as
     so supplemented to be filed pursuant to Rule 424 (or any similar provisions
     then in force) under the Securities Act and comply with the provisions of
     the Securities Act with respect to the disposition of all securities
     covered by such Registration Statement during the applicable period in
     accordance with the intended methods or disposition by the sellers thereof
     set forth in such Registration Statement as so amended or such Prospectus
     as so supplemented. The Company shall ensure that (i) any Shelf
     Registration and any amendment thereto and any Prospectus forming a part
     thereof and any amendment or supplement thereto complies in all material
     respects with the Act and the rules and regulations thereunder, (ii) any
     Shelf Registration and any amendment thereto does not, when it becomes
     effective, contain an untrue statement of a material fact or omit to state
     a material fact required to be stated therein or necessary to make the
     statements therein, in light of the circumstances under which they were
     made, not misleading and (iii) any Prospectus forming part of any Shelf
     Registration, and any amendment or supplement to such Prospectus, does not
     include an untrue statement of a material fact or omit to state a material
     fact necessary in order to make the statements therein, in the light of the
     circumstances under which they were made, not misleading.
 
          (c) Notify each Selling Holder and the Managing Underwriters, if any,
     promptly, and (if requested by any such Person) confirm such notice in
     writing, (i) when a Prospectus, any Prospectus supplement, a Registration
     Statement or a post-effective amendment to a Registration Statement has
     been filed with the SEC, and, with respect to a Registration Statement or
     any post-effective amendment, when the same has become effective; (ii) of
     any request by the SEC or any other federal or state governmental authority
     for amendments or supplements to a Registration Statement or related
     Prospectus or for additional information, (iii) of the issuance by the SEC
     or any other federal or state governmental authority of any stop order
     suspending the effectiveness of a Registration Statement or the initiation
     or threatening of any proceedings for that purpose, (iv) of the receipt by
     the Company of any notification with respect to the suspension of the
     qualification or exemption from qualification of any of the Registrable
     Securities for sale in any jurisdiction or the initiation or threatening of
     any proceedings for such purpose, (v) of the existence of any fact or
     happening of any event which makes any statement of a material fact in such
     Registration Statement or related Prospectus or any document incorporated
     or deemed to be incorporated therein by reference untrue or which would
     require the making of any changes in the Registration Statement or
     Prospectus in order that the Registration Statement will not contain any
     untrue statement of a material fact or omit to state any material fact
     required to be stated therein or necessary to make the statements therein
     not misleading, and that the Prospectus will not contain any untrue
     statement of a material fact or omit to state any material fact required to
     be stated therein or necessary to make the statements therein, in the light
     of the circumstances under which they were made, not misleading, and (vi)
     of the Company's good faith determination that a post-effective amendment
     to a Registration Statement is required by applicable laws, rules or
     regulations.
 
          (d) Use its best efforts to obtain the withdrawal of any order
     suspending the effectiveness of a Registration Statement, or the lifting of
     any suspension of the qualification (or exemption from qualification) of
     any of the Registrable Securities for sale in any jurisdiction, at the
     earliest possible moment.

     post-effective amendment to the Registration Statement such information as
     the Selling Holders or the Managing Underwriters, if any, and the Company
     mutually agree should be included therein, and (ii) make all required
     filings of such Prospectus supplement or such post-effective amendment as
     soon as practicable after the Company has received notification of the
     matters proposed to be incorporated in such Prospectus supplement or
     post-effective amendment.
 
          (f) Furnish to the Selling Holders and each Managing Underwriter, if
     any, without charge, at least one conformed copy of the Registration
     Statement or Statements and any amendment thereto, including financial
     statements but excluding schedules, all documents incorporated or deemed to
     be incorporated therein by reference and all exhibits.
 
          (g) Deliver to each Selling Holder and each Managing Underwriter, if
     any, in connection with any offering of Registrable Securities, without
     charge, as many copies of the Prospectus or Prospectuses relating to such
     Registrable Securities (including each preliminary prospectus) and any
     amendment or supplement thereto as such Persons may reasonably request; and
     the Company hereby consents to the use of such Prospectus or each amendment
     or supplement thereto by each of the Selling Holders and the Underwriters,
     if any, in connection with any offering and sale of the Registrable
     Securities covered by such Prospectus or any amendment or supplement
     thereto.
 
          (h) Prior to any public offering of Registrable Securities, to

     Underwriters, if any, in connection with the registration or qualification
     (or exemption from such registration or qualification) of such Registrable
     Securities for offer and sale under the securities or Blue Sky laws of such
     jurisdictions within the United States as the Selling Holders or Managing
     Underwriters reasonably requests in writing, keep each such registration or
     qualification (or exemption therefrom) effective during the period such
     Registration Statement is required to be kept effective and do any and all
     other acts or things necessary or advisable to enable the disposition in
     such jurisdictions of the Registrable Securities covered by the applicable
     Registration Statement, provided that the Company will not be required to
     (i) qualify generally to do business in any jurisdiction where it is not
     then so qualified or (ii) take any action that would subject it to general
     service of process in suits or to taxation in any jurisdiction where it is
     not then so subject.
 
          (i) Cause the Registrable Securities covered by the applicable
     Registration Statement to be registered with or approved by such other
     governmental agencies in addition to the SEC or authorities within the
     United States as may be necessary to enable each Selling Holder or the
     Managing Underwriters, if any, to consummate the disposition of such
     Registrable Securities.
 
          (j) During the Effectiveness Period (subject to the provisions of
     Section 2(c)), immediately upon the existence of any fact or the occurrence
     of any event as a result of which (i) a Registration Statement shall
     contain any untrue statement of a material fact or omit to state any
     material fact required to be stated therein or necessary to make the
     statements therein, in light of the circumstances under which they were
     made, not misleading, or (ii) a Prospectus shall contain any untrue
     statement of a material fact or omit to state any material fact required to
     be stated therein or necessary to make the statements therein, in the light
     of the circumstances under which they were made, not misleading, promptly
     prepare and file a post-effective amendment to each Registration Statement
     or a supplement to the related Prospectus or any document incorporated
     therein by reference or file any other required document (such as a Current
     Report on Form 8-K) that would be incorporated by reference into the
     Registration Statement so that the Registration Statement shall not contain
     any untrue statement of a material fact or omit to state any material fact
     required to be stated therein or necessary to make the statements therein
     not misleading, in light of the circumstances under which they were made,
     and so that the Prospectus will not contain any untrue statement of a
     material fact or omit to state any material fact required to be stated
     therein or necessary to make the statements therein, in the light of the
     circumstances under which they were made, not misleading, as thereafter
     delivered to the purchasers of the Registrable Securities being sold
     thereunder; and in the case of a post-effective amendment to a Registration
     Statement, use its best efforts to cause it to become effective as soon as
     practicable.

          (k) Enter into such agreements (including, in the event of an
     Underwritten Offering, an underwriting agreement in form, scope and
     substance as is customary in Underwritten Offerings) and take all such
     other actions in connection therewith (including, in the event of an the
     Underwritten Offering, those reasonably requested by the Managing
     Underwriters, if any, or the Holders of a majority of the Registrable
     Securities) in order to expedite or facilitate the disposition of such
     Registrable Securities and in such connection, whether or not an
     underwriting agreement is entered into, and if the registration is an
     Underwritten Registration, (i) make such representations and warranties to
     the Holders and the underwriters with respect to the business of the
     Company and its subsidiaries, the Registration Statement, Prospectus and
     documents incorporated by reference or deemed incorporated by reference, if
     any, in each case, in form, substance and scope as are customarily made by
     issuers to underwriters in underwritten offerings and confirm the same if
     and when requested; (ii) use its best efforts to obtain opinions of counsel
     to the Company and updates thereof (which counsel and opinions (in form,
     scope and substance) shall be reasonably satisfactory to the Managing
     Underwriters, if any, and the Holders of a majority of the Registrable
     Securities) addressed to each of the underwriters covering the matters
     customarily covered in opinions requested in underwritten offerings and
     such other matters as may be reasonably requested by such Managing
     Underwriters; (iii) use its best efforts to obtain "cold comfort" letters
     and updates thereof from the independent certified public accountants of
     the Company (and, if necessary, any other certified public accountants of
     any subsidiary of the Company or any business acquired or to be acquired by
     the Company for which financial statements and financial data are, or are
     required to be, included in the Registration Statement), addressed to each
     of the Managing Underwriters, if any, such letters to be in customary form
     and covering matters of the type customarily covered in "cold comfort"
     letters in connection with Underwritten Offerings, and (iv) deliver such
     documents and certificates as may be reasonably requested by the Holders of
     a majority of the Registrable Securities being sold, the Managing
     Underwriters, if any, to evidence the continued validity of the
     representations and warranties of the Company and its subsidiaries made
     pursuant to clause (i) above and to evidence compliance with any customary
     conditions contained in the underwriting agreement or other agreement
     entered into by the Company. The above shall be done at each closing under
     such underwriting or similar agreement as and to the extent required
     thereunder.
 
          (l) Make available for inspection by a representative of the Selling
     Holders, any Managing Underwriter participating in any disposition of
     Registrable Securities, and any attorney or accountant retained by the
     Selling Holders or such underwriter, financial and other records, pertinent
     corporate documents and properties of the Company and its subsidiaries, and
     cause the executive officers, directors and employees of the Company and
     its subsidiaries to supply all information reasonably requested by any such
     representative, Managing Underwriter, attorney or accountant in connection
     with such disposition; provided, however, that any information that is
     reasonable and in good faith designated by the Company in writing as
     confidential at the time of delivery of such information shall be kept
     confidential by such Persons, unless (i) disclosure of such information is
     required by court or administrative order or is necessary to respond to
     inquiries of regulatory authorities, (ii) disclosure of such information is
     required by law (including any disclosure requirements pursuant to federal
     securities laws in connection with the filing of any Registration Statement
     or the use of any prospectus referred to in this Agreement), (iii) such
     information becomes generally available to the public other than as a
     result of disclosure or failure to safeguard by any such Person or (iv)
     such information becomes available to any such Person from a source other
     than the Company and such source is not bound by a confidentiality
     agreement.
 
          (m) Comply with all applicable rules and regulations of the SEC in all
     material respects and make generally available to its securityholders
     earnings statements (which need not be audited) satisfying the provisions
     of Section 11(a) of the Securities Act and Rule 158 thereunder (or any
     similar rule promulgated under the Securities Act) no later than 45 days
     after the end of any 12-month period (or 90 days after the end of any
     12-month period if such period is a fiscal year) (i) commencing at the end
     of any fiscal quarter in which Registrable Securities are sold to
     underwriters in firm commitment or best efforts underwritten offering and
     (ii) if not sold to underwriters in such an offering, commencing on the
     first day of the first fiscal quarter of the Company commencing after the
     effective date of a Registration Statement, which statements shall cover
     said 12-month periods.

<PAGE>   416
 
          (n) Cooperate with the Selling Holders and the Managing Underwriters,
     if any, to facilitate the timely preparation and delivery of certificates
     representing Registrable Securities to be sold and not bearing any
     restrictive legends, and enable such Registrable Securities to be in such
     denominations and registered in such names as such Selling Holder may
     request.
 
          (o) Cause all shares of Common Stock covered by the Registration
     Statement to be listed on each securities exchange or quotation system on
     which the Company's Common Stock is then listed or quoted no later than the
     date the Registration Statement is declared effective, and, in connection
     therewith, to the extent applicable, to make such filings under the
     Exchange Act (e.g., the filing of a Registration Statement on Form 8-A) and
     to have such filings declared effective thereunder.
 
          (p) Cooperate and assist in any filing required to be made with the
     National Association of Securities Dealers, Inc.
 
     The Company may require each Selling Holder to furnish to the Company such
information regarding such Selling Holder and the distribution of such
securities as the Company, upon advice of counsel, may from time to time
determine to be required under applicable laws, rules and regulations for
inclusion in such Registration Statement. If any Selling Holder fails to provide
such information, then such Selling Holder shall not be entitled to use the
Prospectus.
 
4. REGISTRATION EXPENSES.
 
     All fees and expenses (other than Selling Expenses) incident to the
Company's obligations under this Agreement shall be borne by the Company whether
or not any of the Registration Statements become effective. Such fees and
expenses shall include, without limitation, (i) all registration and filing fees
(including, without limitation, fees and expenses with respect to filings
required to be made with the National Association of Securities Dealers, Inc.),
(ii) printing expenses (including, without limitation, expenses of printing
certificates for Registrable Securities in a form eligible for deposit with The
Depository Trust Company and of printing Prospectuses if the printing of
Prospectuses is requested by the Holders of a majority of the Registrable
Securities or the Managing Underwriters), (iii) reasonable fees and
disbursements of counsel for the Company in connection with the Shelf
Registration (provided that the Company shall not be liable for the fees and
expenses of more than one separate firm for all parties (other than the Company)
participating in any transaction hereunder), and (iv) fees and disbursements of
all independent certified public accountants referred to in Section 3(k)(iii)
hereof (including the expenses of any special audit and "cold comfort" letters
required by or incident to such performance). In addition, the Company shall pay
the fees and expenses incurred in connection with the listing or quotation of
the securities to be registered on any securities exchange or quotations system
on which similar securities issued by the Company are then listed and the fees
and expenses of any Person, including special experts, retained by the Company.
 
5. INDEMNIFICATION.
 
     (a) Indemnification by the Company.  The Company shall indemnify and hold
harmless each Holder, the directors, officers, employees and agents of each
Holder and each Person, if any, who controls any such Holder (within the meaning
of either Section 15 of the Securities Act or Section 20 of the Exchange Act)
from and against all losses, liabilities, damages and expenses (including,
without limitation, any legal or other expenses reasonably incurred in
connection with defending or investigating any such action or claim)
(collectively, "Losses"), arising out of or based upon any untrue statement or
alleged untrue statement of a material fact contained in any Registration
Statement or Prospectus or in any amendment or supplement thereto, or arising
out of or based upon any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, in light of the circumstances under which they were
made, except insofar as such Losses arise out of or are based upon the
information relating to such Holder furnished to the Company in writing by such
Holder expressly for use therein; provided, however, that the Company shall not
be liable in any such case to the extent that any such loss, damage, liability
or expense arises out of or is based upon an untrue statement or alleged untrue
statement or omission or alleged omission made in any preliminary prospectus if
(i) such Holder failed to send
 
                                      E-71
<PAGE>   417
 
or deliver a copy of the Prospectus with or prior to the delivery of written
confirmation of the sale of Registrable Securities and (ii) the Prospectus would
have corrected such untrue statement or omission; and provided further, that the
Company shall not be liable in any such case to the extent that any such loss,
damage, liability or expense arises out of or is based upon an untrue statement
or alleged untrue statement or omission or alleged omission in the Prospectus,
if such untrue statement or alleged untrue statement, omission or alleged
omission is corrected in an amendment or supplement to the Prospectus and if,
having previously been furnished by or on behalf of the Company with copies of
the Prospectus as so amended or supplemented, such Holder thereafter fails to
deliver such Prospectus, as so amended or supplemented, prior to or concurrently
with the sale of a Registrable Security to the person asserting such loss,
damage, liability or expense who purchased such Registrable Security which is
the subject thereof from such Holder. The Company shall also indemnify each
underwriter, their officers and directors, and each Person who controls such
Person (within the meaning of Section 15 of the Securities Act or Section 20 of
the Exchange Act) to the same extent and with the same limitations as provided
above with respect to the indemnification of the Holders.
 
     (b) Indemnification by Holders.  Each Holder agrees severally and not
jointly to indemnify and hold harmless the Company, its directors, its officers
who sign a Registration Statement and each Person, if any, who controls the
Company (within the meaning of either Section 15 of the Securities Act or
Section 20 of the Exchange Act), from and against all losses arising out of or
based upon any untrue statement of a material fact contained in any Registration
Statement, Prospectus or arising out of or based upon any omission of a material
fact required to be stated therein or necessary to make the statements therein
not misleading, in light of the circumstances under which they were made, to the
extent, but only to the extent, that such untrue statement or omission is
contained in any information relating to such Holder so furnished in writing by
such Holder to the Company expressly for use in such Registration Statement or
Prospectus. In no event shall the liability of any Holder hereunder be greater
in amount than the dollar amount of the proceeds received by such Holder upon
the sale of the Registrable Securities giving rise to such indemnification
obligation.
 
     (c) Conduct of Indemnification Proceedings.  In case any proceeding
(including any governmental investigation) shall be instituted involving any
Person in respect of which indemnity may be sought pursuant to either of the two
preceding paragraphs, such Person (the "Indemnified Party") shall promptly
notify the Person against whom such indemnity may be sought (the "Indemnifying
Party") in writing, but failure so to notify an Indemnifying Party shall not
relieve such Indemnifying Party from any liability hereunder to the extent it is
not materially prejudiced as a result thereof. The Indemnifying Party, upon
request of the Indemnified Party, shall retain counsel satisfactory to the
Indemnified Party to represent the Indemnified Party and any others the
Indemnifying Party may designate in such proceeding and shall pay the fees and
disbursements of such counsel related to such proceeding. In any such
proceeding, any Indemnified Party shall have the right to retain its own
counsel, but the fees and expenses of such counsel shall be at the expense of
such Indemnified Party unless (i) the Indemnifying Party and the Indemnified
Party shall have mutually agreed to the retention to such counsel (ii) the named
parties to any such proceeding (including any impleaded parties) include both
the Indemnifying Party and the Indemnified Party and representation of both
parties by the same counsel would be inappropriate due to actual or potential
differing interests between them, or (iii) the Indemnifying Party shall not have
employed counsel satisfactory to the Indemnified Party to represent the
Indemnified Party within a reasonable time after notice of commencement of the
action. It is understood that the Indemnifying Party shall not, in respect of
the legal expenses of any Indemnified Party in connection with any proceeding or
related proceedings in the same jurisdiction, be liable for the fees and
expenses of more than one separate firm (in addition to any local counsel) for
all indemnified parties under Section 5(a) or 5(b) hereof who are parties to
such proceeding or proceedings, and that all such fees and expenses shall be
reimbursed as they are incurred. The Indemnifying Party shall not be liable for
any settlement of any proceeding effected without its written consent, but if
settled with such consent or if there be a final judgment for the plaintiff, the
Indemnifying Party agrees to indemnify the Indemnified Party from and against
any loss or liability by reason of such settlement or judgment. Notwithstanding
the foregoing sentence, if at any time an Indemnified Party shall have requested
an Indemnifying Party to reimburse the Indemnified Party for fees and expenses
of counsel as contemplated by the second and third sentences of this paragraph,
such Indemnifying Party agrees that it shall be liable for any settlements of
any proceeding effected without its
                                      E-72
<PAGE>   418
 
written consent if (i) such settlement is entered into more than 45 days after
receipt by such Indemnifying Party of the aforesaid request and (ii) such
Indemnifying Party shall not have reimbursed the Indemnified Party in accordance
with such request prior to the date of such settlement. No Indemnifying Party
shall, without the prior written consent of the Indemnified Party, effect any
settlement of any pending or threatened proceeding in respect of which any
Indemnified Party is or could have been a party and indemnity could have been
sought hereunder by such Indemnified Party, unless such settlement includes an
unconditional release of such Indemnified Party from all liability on claims
that are the subject matter of such proceeding.
 
     (d) Contribution.  If the indemnification provided for in this Section 5 is
unavailable to an Indemnified Party under Section 5(a) or 5(b) hereof in respect
of any Losses or is insufficient to hold such Indemnified Party harmless, then
each applicable Indemnifying Party, in lieu of indemnifying such Indemnified
Party, shall contribute to the amount paid or payable by such Indemnified Party
as a result of such Losses, (i) in such proportion as is appropriate to reflect
the relative benefits received by the Indemnifying Party or Indemnifying Parties
on the one hand and the Indemnified Party or Indemnified Parties an the other
hand or (ii) if the allocation provided by clause (i) above is not permitted by
applicable law, in such proportion as is appropriate to reflect not only the
relative benefits referred to in clause (i) above but also the relative fault of
the Indemnifying Party or Indemnified Parties on the one hand and of the
Indemnified Party or Indemnifying Parties on the other hand in connection with
the statements or omissions that resulted in such Losses, as well as any other
relevant equitable considerations. Benefits received by the Company shall be
deemed to be equal to the total number of Registrable Shares multiplied by the
per share closing price of the Common Stock on the Closing Date, as listed on
the Nasdaq National Market. Benefits received by the Holders shall be deemed to
be equal to the value of receiving the Registrable Shares and having such shares
registered under the Securities Act. Benefits received by any underwriter shall
be deemed to be equal to the total underwriting discounts and commissions, as
set forth on the cover page of the Prospectus forming a part of the Registration
Statement which resulted in such Losses. The relative fault of the Holders on
the one hand and the Company on the other hand shall be determined by reference
to, among other things, whether the untrue or alleged untrue statement of a
material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Holders or by the Company and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission.
 
     The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 5(d) were determined by pro rata
allocation or by any other method or allocation that does not take into account
the equitable considerations referred to in the immediately preceding paragraph.
The amount paid or payable by an Indemnified Party as a result of the Losses
referred to in the immediately preceding paragraph shall be deemed to include,
subject to the limitations set forth above, any legal or other expenses
reasonably incurred by such Indemnified Party in connection with investigating
or defending any such action or claim. Notwithstanding this Section 5(d), a
Selling Holder shall not be required to contribute any amount in excess of the
amount by which the total price at which the Registrable Securities sold by such
Selling Holder and distributed to the public were offered to the public exceeds
the amount of any damages which such Selling Holder has otherwise been required
to pay by reason of such untrue or alleged untrue statement or omission or
alleged omission. No Person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any Person who was not guilty of such fraudulent
misrepresentation. The indemnity, contribution and expense reimbursement
obligations of the Company hereunder shall be in addition to any liability the
Company may otherwise have hereunder, under the Purchase Agreement or otherwise.
 
     The indemnity and contribution provisions contained in this Section 5 shall
remain operative and in full force and effect regardless of (i) any termination
of this Agreement, (ii) any investigation made by or on behalf of any Holder or
any Person controlling any Holder, or the Company, its officers or directors or
any Person controlling the Company and (iii) the sale of any Registrable
Securities by any Selling Holder.
 
6. INFORMATION REQUIREMENTS.
 
     (a) The Company shall file the reports required to be filed by it under the
Securities Act and the Exchange Act, and if at any time the Company is not
required to file such reports, it will, upon the request of
                                      E-73
<PAGE>   419
 
any Holder of Registrable Securities, make publicly available other information
so long as necessary to permit sales pursuant to Rule 144 under the Securities
Act. The Company further covenants that it will cooperate with any Holder and
take such further reasonable action as any such Holder may reasonably request
(including, without limitation, making such reasonable representations as any
such Holder may reasonably request), all to the extent required from time to
time to enable such Holder to sell Registrable Securities without registration
under the Securities Act within the limitation of the exemptions provided by
Rule 144 under the Securities Act. Notwithstanding the foregoing, nothing in
this Section 6 shall be deemed to require the Company to register any of its
securities under any Section of the Exchange Act.
 
     (b) The Company shall file the reports required to be filed by it under the
Exchange Act and shall comply with all other requirements set forth in the
instructions to the appropriate SEC Registration Statement form permitting
registration of the Registrable Securities for resale by the Holders in the
manner or manners designated by them.
 
7. VOLUME LIMITATIONS.
 
     Notwithstanding anything herein to the contrary, (i) no Holder may sell any
Registrable Securities, without the prior written consent of the Company, prior
to the Effectiveness Target Date, except that without such consent, Purchaser
may sell the Registrable Securities to a buyer that acquires such Registrable
Securities for investment and not with a view toward distribution thereof
otherwise than pursuant to the terms of this Agreement, and (ii) thereafter no
Holder may sell more than 12.5% of the Registrable Securities held by such
Holder in any one month period, provided that a Holder may effect a block trade
(within the meaning of New York Stock Exchange Rule 127.10) of any amount of
Registrable Securities upon five (5) days prior written notice to the Company.
 
8. OTHER COVENANTS OF THE PURCHASER.
 
     Neither the Purchaser nor any Person controlled by, related to or
affiliated with the Purchaser (collectively, the "Stockholder Group") shall,
directly or indirectly, acquire any shares of capital stock of the Company which
are then entitled to vote generally in the election of directors (the "Voting
Securities") (except by way of stock dividend or other distributions or
offerings made available to holders of Voting Securities generally) if the
effect of such acquisition would be to increase the aggregate voting power in
the election of directors of all Voting Securities then owned by all members of
the Stockholder Group to greater than 15% of such total combined voting power of
all the Voting Securities then outstanding.
 
9. MISCELLANEOUS.
 
     (a) Remedies.  In the event of a breach by the Company of its obligations
under this Agreement, each Holder, in addition to being entitled to exercise all
rights granted by law, including recovery of damages, will be entitled to
specific performance of its rights under this Agreement. The Company agrees that
monetary damages would not be adequate compensation for any loss incurred by
reason or a breach by it of any of the provisions of this Agreement and hereby
further agrees that, in the event of any action for specific performance in
respect of such breach, it shall waive the defense that a remedy at law would be
adequate.
 
     (b) No Conflicting Agreements.  The Company has not entered, as of the date
hereof and shall not, on or after the date of this Agreement, enter into any
agreement with respect to its securities which conflicts with the rights granted
to the Holders in this Agreement. The Company represents and warrants that the
rights granted to the Holders hereunder do not in any way conflict with the
rights granted to the holders of the Company's securities under any other
agreements.
 
     (c) Amendments and Waivers.  The provisions of this Agreement, including
the provisions of this sentence, may not be amended, modified or supplemented,
and waivers or consents to departures from the provisions hereof may not be
given, unless the Company has obtained the written consent of the Holders of a
majority of the Registrable Securities.

                           INDEMNIFICATION AGREEMENT
 
     INDEMNIFICATION AGREEMENT (the "Agreement"), dated                  , 1998,
by and among WORLD ACCESS, INC., a Delaware corporation with its principal
office at 945 East Paces Ferry Road, Suite 2240, Atlanta, Georgia 30326 (the
"Buyer"), GST TELECOMMUNICATIONS, INC., a federally chartered Canadian
corporation ("GST"), and GST USA, INC., a Delaware corporation (the "Seller"),
each with their principal offices at 4001 Main Street, Vancouver, Washington
98663.
 
                                  WITNESSETH:
 
     WHEREAS, NACT Telecommunications, Inc., a Delaware corporation (the
"Company"), is engaged in the business of providing advanced telecommunications
switching platforms with integrated applications software and network
telecommunications capabilities; and
 
     WHEREAS, Seller is a wholly-owned subsidiary of GST and is the record and
beneficial owner of 5,113,712 shares (the "Shares") of the common stock, $.01
par value per share (the "Common Stock"), of the Company; and
 
     WHEREAS, Buyer, GST and Seller are parties to that certain Stock Purchase
Agreement, dated December 31, 1997 (the "Stock Purchase Agreement"), pursuant to
which Seller is selling to Buyer, and Buyer is purchasing from Seller, the
Shares; and
 
     WHEREAS, there are, and subsequent to the sale of the Shares to Buyer,
there will be, issued and outstanding shares of Common Stock held of record
and/or beneficially by stockholders of the Company other than Buyer (such shares
of Common Stock and any and all additional shares of Common Stock from time to
time outstanding subsequent to such sale and held by such stockholders being
hereinafter referred to as the "Minority Shares"); and
 
     WHEREAS, it is a condition to the sale of the Shares that Buyer provide
indemnification in respect of any Damages (as hereinafter defined) to Seller,
GST and their Affiliates, as such term is defined in the rules and regulations
promulgated under the Securities Act of 1933, as amended (Seller, GST and their
Affiliates being hereinafter referred to individually as an "Indemnified Party"
and collectively as the "Indemnified Parties");
 
     NOW, THEREFORE, in consideration of the premises, and the covenants and
agreements contained herein and in the Stock Purchase Agreement, the parties
hereby agree as follows:
 
     SECTION 1.  Indemnification Obligations.
 
     (a) Buyer shall indemnify and hold harmless the Indemnified Parties, and
each of them, from, against, for and in respect of any and all losses,
liabilities, damages, demands, obligations, judgments, fines, deficiencies,
encumbrances, assessments, costs and expenses including, without limitation,
interest, penalties and reasonable attorneys' fees, incident to any action,
suit, claim, proceeding or investigation commenced or threatened by or on behalf
of any holder of Minority Shares and by any governmental or quasi-governmental
agency, board, bureau, commission or other instrumentality, and any and all
amounts paid in settlement of any such action, suit, claim, proceeding or
investigation, asserted against, resulting to, imposed upon, or incurred or
suffered by the Indemnified Parties, or any of them, in each case in respect of
the purchase or attempted purchase by Buyer or any designee thereof of the
Minority Shares or any of them, whether by tender or exchange offer,
acquisition, merger, open market purchase or otherwise (all hereinafter
collectively referred to as "Damages"). Notwithstanding anything herein to the
contrary, Buyer shall have no obligation to any of the Indemnified Parties under
this Section 1 in respect of the business or operations of the Company prior to
the Closing (as defined in the Stock Purchase Agreement) or the actions or
omissions of the Company's officers, directors, stockholders, employees or
agents prior to the Closing, irrespective of the date that any claim, suit or
other cause of action related thereto is filed or otherwise instituted,
provided, however, that nothing contained
 
                                      E-78
<PAGE>   424
 
herein shall be construed to limit or negate the indemnification obligations
provided for in the Stock Purchase Agreement.
 
     (b) For purposes of this Agreement, all Damages shall be computed net of
any insurance coverage with respect thereto that reduces the Damages that would
otherwise be sustained by any of the Indemnified Parties; provided, however,
that in all cases, the timing of the receipt or realization of insurance
proceeds shall be taken into account in determining the amount of reduction of
Damages.
 
     SECTION 2.  Procedure for Indemnification with Respect to Indemnifiable
Claims.  Seller, for itself and on behalf of any Indemnified Party, shall give
Buyer prompt written notice of any action, suit, claim, investigation or
proceeding to which the indemnification provided in this Agreement applies (each
an "Indemnifiable Claim"), which notice shall describe such Indemnifiable Claim
in reasonable detail (the "Indemnification Notice"). Notwithstanding the
foregoing, Seller shall not have any obligation to give any notice to Buyer of
any assertion by a third party that could give rise to an Indemnifiable Claim
unless such assertion is in writing, and the rights of any Indemnified Party to
be indemnified hereunder in respect of any Indemnifiable Claim shall not be
adversely affected by Seller's failure to give notice thereof as herein
provided, unless and, if so, only to the extent that, Buyer is materially
prejudiced thereby.
 
     Buyer shall have the right to control the defense or settlement of any such
Indemnifiable Claim employing counsel and other professionals reasonably
satisfactory to the Indemnified Party, subject to the provisions set forth
below, but the Indemnified Party may, at its election, participate in the
defense of any action, suit, claim, investigation or proceeding at its sole cost
and expense. Notwithstanding the foregoing, if there exists a conflict of
interest that would make it inappropriate for the same counsel to represent both
the Indemnified Party, on the one hand, and Buyer, on the other hand, in
connection with any Indemnifiable Claim, then the Indemnified Party shall be
entitled to retain its own counsel as is reasonably satisfactory to Buyer at
Buyer's expense; provided that Buyer shall not be obligated to pay the
attorneys' fees of more than one separate counsel under the Agreement. In the
event that such Indemnified Party shall seek indemnification as provided herein,
such Indemnified Parties shall make available to Buyer, at Buyer's expense, all
witnesses, pertinent records, materials and information in the Indemnified
Party's possession or under the Indemnified Party's control relating thereto as
is reasonably required by Buyer.
 
     Should Buyer fail to defend any such action (except for failure resulting
from Seller's failure to timely give the Indemnification Notice) within 20 days
after the date of receipt of the Indemnification Notice, then, in addition to
any other remedy, the Indemnified Party may settle or defend any such action,
suit, claim, investigation or proceeding through counsel of its own choosing and
may recover from Buyer the amount of its Damages. Except as provided in the
preceding sentence, no Indemnified Party shall compromise or settle any
Indemnifiable Claim without the prior written consent of Buyer, which consent
shall not be unreasonably withheld; provided, however, that if Buyer's consent
is unreasonably withheld, the liability of Buyer shall be limited to the amount
of the proposed compromise or settlement and the amount of the Indemnified
Party's reasonable counsel fees incurred in defending such claim, as permitted
by the preceding sentence, at the time such approval is unreasonably withheld.
Notwithstanding the preceding sentence, the right of the Indemnified Party to
compromise or settle any such action, suit, claim, investigation or proceeding
shall only be available if a complete release of Buyer is contemplated to be
part of such proposed compromise or settlement.
 
3. EXCLUSIVITY; SURVIVAL.
 
     Any and all Indemnifiable Claims shall be subject to the terms and
conditions of this Agreement, and shall survive the execution and delivery of,
and the consummation of the transactions contemplated by, the Stock Purchase
Agreement.
 
4. MISCELLANEOUS PROVISIONS.
 
     (a) Notices.  All notices and other communications required or permitted

     party hereto may have otherwise agreed to in writing, no waiver by that
     party of any condition of this Agreement or breach by any other party of
     any of its obligations hereunder shall be deemed to be a waiver of any
     other condition or subsequent or prior breach of the same or any other
     obligation by such other party, nor shall any forbearance by any party to
     seek a remedy for any noncompliance or breach by any other party be deemed
     to be a waiver by any party of its rights and remedies with respect to such
     noncompliance or breach.

FOR IMMEDIATE RELEASE
 
     ATLANTA, GEORGIA -- January 2, 1998 -- WORLD ACCESS, INC. (NASDAQ: WAXS),
announced today that it has signed a definitive agreement with GST
Telecommunications, Inc. ("GST") and GST USA, Inc., a wholly owned subsidiary of
GST ("GST USA"), to acquire 4,105,043 shares of NACT Telecommunications, Inc.
("NACT") common stock held by GST USA. NACT (NASDAQ: NACT) is a Provo, Utah
based provider of advanced telecommunications switching platforms with
integrated applications software and network telemanagement capabilities. NACT's
customers include national and international long distance carriers, prepaid
debit and prepaid cellular network operators, international
callback/reorigination providers and other specialty telecommunications service
providers.
 
     Pursuant to the terms of a Stock Purchase Agreement, World Access will pay
GST $17.50 per share of NACT common stock, or approximately $71.8 million, $59.6
million of which will be paid in cash and $12.2 million of which will be paid
through the issuance of shares of World Access common stock. The completion of
this transaction, currently scheduled for mid-February, will raise World Access'
equity ownership in NACT to approximately 55%. In addition, GST has the option
under the Agreement to sell World Access the remaining 1,008,669 shares of NACT
common stock held by GST USA at the same price of $17.50 per share, or
approximately $17.7 million, payable through the issuance of shares of World
Access common stock. IF GST elects to exercise this option, World Access' equity
ownership in NACT will increase to approximately 67%.
 
     World Access intends to promptly propose a merger with NACT pursuant to
which all of the shares of NACT common stock not owned by World Access would be
exchanged for shares of World Access common stock. The merger would be
contingent upon the completion of the GST stock purchase.
 
     World Access also announced today, that upon the completion of its pending
acquisition of Advanced TechCom, Inc. ("ATI") and the NACT stock purchase, it
expects to record a significant one-time charge to earnings for in-process ATI
and NACT research and development projects and other related costs. The exact
amount of the one-time charge has not yet been determined.
 
     Steven A. Odom, Chairman and Chief Executive Officer, said "The acquisition
of NACT, which is expected to be accretive to World Access' 1998 earnings, is in
line with the Company's strategy to broaden its offering of switching, transport
and access products and fully support its customers as they build new and/or
upgrade existing telecommunications networks. NACT has been providing its
customers comprehensive telecommunications network equipment and services since
1982. It has enjoyed considerable growth and success in recent years since the
introduction of its STX tandem switch in February 1996. The STX switch, when
combined with NACT's multi-tasking billing systems, provide a turnkey package
for the emerging interexchange carrier industry. We believe that the STX switch
represents today's benchmark for the fast growing, specialty application
switching systems industry."
 
     "We are particularly pleased that Lindsay Wallace, President and Chief
Executive Officer of NACT, will continue to manage NACT as a majority owned
subsidiary of World Access. Under the leadership of Mr. Wallace, and his
outstanding team of engineering, sales and operations professionals, NACT
reported record revenues of $27.7 million and pre-tax income of $6.3 million in
its most recently completed fiscal year,
 
                                      E-92

increases of 70% and 2200%, respectively from the previous year's results. We
are optimistic that World Access' financial strength, extensive customer base,
engineering capabilities and broad range of manufacturing and support services
will further support NACT's existing business and provide additional sales and
profit growth opportunities for both companies."
 
     Mr. Odom added, "World Access will be sponsoring a conference call on
Monday, January 5th at 4:30 E.S.T. to further review the strategic and financial
impact of the NACT and ATI acquisitions with our shareholders and other
interested parties. Further information on the conference call will be released
later today."

     A.  Public Announcements.  Target will not, at any time, without the prior
written consent of Acquiror, make any announcement, issue any press release or

law, regulation or order and then only after prior written notice to Acquiror of
the timing, context and content of such announcement, press release or
statement.
 
     B.  Termination.  This letter of intent may be terminated (i) by mutual
consent of the parties; or (ii) by either party if the Definitive Agreement has
not been executed by April 30, 1998.

FOR IMMEDIATE RELEASE
 
     ATLANTA, GEORGIA -- February 12, 1998 -- WORLD ACCESS, INC. (NASDAQ: WAXS),
announced today that it has signed a letter of intent to acquire Cherry
Communications Incorporated (d/b/a Resurgens Communications Group) ("Resurgens")
in a merger transaction upon terms to be negotiated. Resurgens, currently
operating under the protection of Chapter 11 of the United States Bankruptcy
Code, is a facilities-based provider of international network access, commonly
referred to in the industry as a carriers' carrier. Resurgens had revenues of
approximately $180 million in 1997.
 
     The transaction is subject to, among other things, the satisfactory
completion by World Access 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. World Access has retained The Robinson-Humphrey Company,
Inc. as its financial advisor in connection with the transaction.
 
     In October 1997, John D. ("Jack") Phillips entered into a series of
agreements whereby, among other things, he became the new Chairman and Chief
Executive Officer of Resurgens and Resurgens was placed into bankruptcy.
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. Upon consummation of
the anticipated Plan of Reorganization, WorldCom is expected to own
approximately 55% of the outstanding stock of Resurgens.
 
     Steven A. Odom, Chairman and Chief Executive Officer of World Access, said,
"The acquisition of Resurgens would be in line with the Company's strategy to
provide its customers with a complete telecommunications network solution,
including switching, transport and access products and related services. The
international network access product offered by Resurgens is a critical element
of new and expanded networks currently being planned or implemented by many
customers of World Access. We believe the ability to offer both equipment and
network access would provide World Access with a more comprehensive and
cost-competitive product offering, especially for international competitive
local exchange providers ("CLECs") and other providers of phone service in
emerging growth markets."
 
     "We are excited that Jack Phillips, a director of World Access, has agreed
to serve as the Chairman of the combined company upon consummation of the
transaction. He is one of the pioneers of the U.S alternative long distance
business, having built up Advanced Telecommunications Corporation, which merged
with WorldCom in 1992, and Resurgens Communications Group, Inc., which merged
with Metromedia Communications Corporation and WorldCom in 1993. We are also
extremely pleased that WorldCom, a recognized leader in today's
telecommunications industry, will become the largest stockholder of the combined
company in the event the transaction is consummated."
 
     John D. Phillips, Chairman and Chief Executive Officer of Resurgens, said
"Steve Odom and his management team have done a tremendous job over the past
three years of building World Access into a highly respected, fast growing
telecommunications equipment manufacturer. Steve will continue to serve as the
Chief Executive Officer of the combined company and I look forward to working
with him as we continue to work towards achieving significant long-term value
for World Access stockholders. Upon consummation of the Resurgens merger, World
Access will be exceptionally well positioned to provide its customers a unique,
comprehensive and value-added telecommunications network solution and to pursue
the significant growth opportunities present within the worldwide
telecommunications markets."

FOR IMMEDIATE RELEASE
 
     ATLANTA, GEORGIA -- February 12, 1998 -- WORLD ACCESS, INC. (NASDAQ: WAXS),
announced today that during the fourth quarter of 1997 it shipped approximately
$9.4 million of switching equipment to Cherry Communications Incorporated (d/b/a
Resurgens Communications Group) ("Resurgens"). Earlier today in a separate press
release, World Access announced that it has signed a letter of intent to acquire
Resurgens. In view of the execution of the letter of intent, World Access will
not record the shipment to Resurgens as revenue in the fourth quarter of 1997.
As a result, the Company will not meet analysts' consensus estimates for the
fourth quarter and year ended December 31, 1997. Accordingly, the Company has
delayed its previously scheduled release of financial results for the fourth
quarter and the year ended December 31, 1997 pending the outcome of its
negotiations with Resurgens.

ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS
 
     On December 31, 1997, GST Telecommunications, Inc., a federally chartered
Canadian corporation ("GST"), GST USA, Inc., a Delaware corporation ("GST USA"),
and World Access, Inc. ("World Access") entered into a Stock Purchase Agreement
(the "Purchase Agreement"), pursuant to which World Access has agreed to
purchase from GST USA (hereinafter referred to as the "Acquisition") 5,113,712
shares of the common stock of NACT Telecommunications, Inc. ("NACT") held by GST
USA (hereinafter referred to as the "Shares"), representing approximately 63% of
the outstanding shares of NACT common stock, $.01 par value per share (the "NACT
Common Stock").
 
     On February 27, 1998, the Acquisition was consummated and World Access paid
to GST USA cash in the amount of $59,662,956 and delivered to GST USA 1,429,907
shares of World Access common stock (the "World Access Common Stock"). The
foregoing summary of the Acquisition is qualified in its entirety by reference
to the terms of the Purchase Agreement and the exhibits thereto, which are
included as Exhibit 2.1 hereto.
 
     In connection with the consummation of the Acquisition, W. Gordon
Blankstein, Stephen Irwin, Robert Olson and Clifford V. Sander, each designees
of GST USA, resigned from NACT's Board of Directors and Steven A. Odom, Hensley
E. West, Mark A. Gergel and Scott N. Madigan, each executive officers of World
Access, were appointed to fill the vacancies thus created.
 
     The consideration paid pursuant to the Purchase Agreement was determined as
a result of negotiations between World Access and GST and the Acquisition was
approved by the boards of directors of World Access, GST and NACT. Prior to the
Acquisition, neither World Access nor any of its affiliates, directors or
officers, nor any associate of any such director or officer, had any
relationship with GST, GST USA or NACT.
 
     Between November 12, 1997 and December 9, 1997, World Access purchased an
aggregate of 355,000 shares of NACT Common Stock in open market purchase
transactions (the "Open Market Purchase"). Accordingly, after the completion of
the Acquisition World Access now owns approximately 68% of the outstanding NACT
Common Stock.
 
     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 will be converted
into shares of World Access Common Stock having a value of $17.50 per share
based on the average of the daily closing price of the World Access Common Stock
on the NASDAQ National Market on each of the twenty consecutive trading days
ending with the third day immediately preceding the effective time of the merger
(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
World Access Common stock, and if the Closing Price is less than $20.88, then
World Access can terminate the agreement. The merger agreement was negotiated on
behalf of NACT by a Special Committee of the NACT Board and has been approved by
the Boards of Directors of NACT and World Access. In addition, NACT has received
a fairness opinion with respect to the merger from NationsBanc Montgomery
Securities LLC. The merger is subject to, among other things, the approval of
the NACT stockholders and the satisfaction of certain other customary
conditions.

                         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.
 
     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>

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 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

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.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
(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.
 
     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:

     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.

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

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.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
(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 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 FINANCIAL STATEMENTS
 
1.  BASIS OF PRESENTATION
 
     The interim financial statements included herein have been prepared by NACT
Telecommunications, Inc. 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 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 December 31, 1997 and September 30, 1997, and the results of its operations
and cash flows for the three month periods ended December 31, 1997 and 1996. 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 issued Statement
of Financial Accounting Standards No. 128, Earnings per Share (SFAS 128). SFAS
128 established a different method of computing earnings per share than these
same computations under the provisions of Accounting Principles Board Opinion
No. 15. Under SFAS 128, the Company is required to present both basic earnings
per share and diluted earnings per share. SFAS 128 is effective for both interim
and annual periods ending after December 15, 1997. Accordingly, the Company has
adopted SFAS 128 in the first quarter of fiscal 1998.
 
     Basic earnings per share is computed based on the weighted average number
of common shares outstanding during the three month periods ended December 31,
1997 and 1996. Diluted earnings per share for the three month periods ended
December 31, 1997 and 1996 is computed considering the dilutive effect of stock
options, and is not materially different from the basic earnings per share
calculations.
 
3.  STOCK PLAN
 
     The Company's 1996 Stock Option Plan (the "Stock Option Plan") was approved
by the Board of Directors and sole stockholder of the Company on November 26,
1996. The purpose of the Stock Option Plan is to create additional incentives
for the Company's employees, directors and others who perform substantial
services to the Company by providing an opportunity to purchase shares of the
Common Stock pursuant to the exercise of options granted under the Stock Option
Plan. The Company may grant options that qualify as incentive stock options
under Section 422 of the Internal Revenue Code, and non-qualified stock options.
Incentive stock options may be granted to employees (including officers and
directors who are employees). Non-qualified stock options may be granted to
employees, officers, directors, independent contractors and consultants of the
Company. As of December 31, 1997, 1,250,000 shares were reserved for issuance
under the Stock Option Plan and options to purchase 1,039,065 shares of Common
Stock were outstanding.
 
     Options become exercisable at such times and in such installments as the
Board of Directors or Compensation Committee provides. The Stock Option Plan
will terminate on November 25, 2006, unless earlier terminated by the Board of
Directors.

          (b) Pro Forma Financial Information.  The Acquisition and Open Market
     Purchase has been accounted for using the purchase method of accounting. In
     connection with the Acquisition, World Access expects to record a charge of
     approximately $43.5 million, representing the portion of the purchase price
     allocated to in-process research and development. The following unaudited
     pro forma consolidated balance sheet as of September 30, 1997 reflects the
     Acquisition (together with the Open Market Purchase) as if it had been
     completed on September 30, 1997. The following unaudited pro forma
     consolidated statement of operations for the year ended December 31, 1996
     and the nine months ended September 30, 1997 reflect the Acquisition
     (together with the Open Market Purchase) as if it had been completed as of
     January 1, 1996.
 
     The pro forma data does not purport to be indicative of the results which
would actually have been reported if the Acquisition (together with the Open
Market Purchase) had occurred on such dates or which may be reported in the
future. The pro forma data should be read in conjunction with the historical
consolidated financial statements of World Access, the historical consolidated
financial statements of NACT, and the related notes thereto.

            NOTES TO UNAUDITED PRO FORMA CONSOLIDATED BALANCE SHEET
 
(A) Represents the pro forma balance sheet for World Access, Inc. as presented
    in the Report on Form 10Q for the Three Months Ended September 30, 1997. The
    pro forma balance sheet presented above includes the effects of the sale of
    $115 million 4.5% convertible subordinated notes which was completed in
    October 1997.
 
(B)  Represents the historical balance sheet of NACT Telecommunications, Inc. as
     of September 30, 1997.
 
(C) The Acquisition 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 in-process
    research and development projects of NACT will be expensed at the
    consummation of the Acquisition. The amount of the one-time non-recurring
    charge is expected to be approximately $43.5 million. Since this charge is
    directly related to the Acquisition and will not recur, the pro forma
    statements of operations have been prepared excluding this charge. The
    Company has not yet determined the final allocation of the purchase price,
    and accordingly, the amount shown below may differ from the amounts
    ultimately determined.
 
     The unallocated excess of purchase price over net assets acquired is
determined as follows (in thousands):

     SECTION 1.3.  Effect of the Mergers.  At the Effective Time, the World
Access Merger and the NACT Merger shall have the effects set forth in the DGCL.
 
     SECTION 1.4.  Charter and Bylaws.  At the Effective Time: (i) with respect

World Access Surviving Corporation until further amended as provided therein and
in accordance with applicable Law; (ii) with respect to the NACT Merger, the
certificate of incorporation and bylaws of Sub-2, as in effect on the date

(iii) the certificate of incorporation of Holdco as in effect immediately prior
to the Effective Time shall be amended at the Effective Time so that Article I

and in accordance with applicable Law.
 
     SECTION 1.5.  Directors and Officers.  From and after the Effective Time,
the directors and officers of each of World Access and NACT shall be the

                                   ARTICLE 2.
 
                              CONVERSION OF STOCK
 
     SECTION 2.1.  Conversion of Sub-1 Stock and World Access Stock.  Subject to
the terms and conditions of this Agreement, as of the Effective Time and by
virtue of the World Access Merger and without any further action on the part of
the holder of any Sub-1 Stock or World Access Stock:
 
          (a) all shares of World Access Stock which are held by World Access as
     treasury stock shall be canceled and retired, and no consideration shall be
     paid or delivered in exchange therefor;
 
                                      G-35
<PAGE>   486
 
          (b) each share of World Access Stock outstanding immediately prior to
     the Effective Time shall be canceled and converted solely into the right to
     receive and be exchangeable for one share of common stock, $.01 par value
     per share (the "Holdco Stock"), of Holdco (the "World Access
     Consideration"); and
 
          (c) each share of Sub-1 Stock issued and outstanding immediately prior
     to the Effective Time shall be converted solely into one fully paid and
     nonassessable share of common stock, par value $.01 per share, of the World
     Access Surviving Corporation.
 
     SECTION 2.2.  Conversion of Sub-2 Stock and NACT Stock.  Subject to the
terms and conditions of this Agreement, as of the Effective Time and by virtue
of the NACT Merger and without any further action on the part of the holder of
any Sub-2 Stock or NACT Stock:
 
          (a) all shares of NACT Stock which are held by NACT as treasury stock
     shall be canceled and retired, and no consideration shall be paid or
     delivered in exchange therefor;
 
          (b) subject to Section 2.3 hereof, each share of NACT Stock
     outstanding immediately prior to the Effective Time shall be canceled and
     converted solely into the right to receive and become exchangeable for that
     number of shares of Holdco Stock equal to the quotient of (x) $17.50
     divided by (y) the Closing Date Market Price (the "Exchange Ratio");
     provided, however, that (i) if the Closing Date Market Price is less than
     $20.88, then World Access may terminate this Agreement by delivering notice
     of termination to NACT in the manner contemplated by Section 10.2 hereof,
     and (ii) if the Closing Date Market Price is more than $25.52, then the
     Exchange Ratio shall be equal to 0.6857 (the number of shares of Holdco
     Stock into which each share of NACT Stock shall be convertible pursuant to
     this Section 2.2(b) is hereinafter referred to as the "NACT
     Consideration"); and
 
          (c) each share of Sub-2 Stock issued and outstanding immediately prior
     to the Effective Time shall be converted solely into one fully paid and
     nonassessable share of common stock, par value $.01 per share, of the NACT
     Surviving Corporation.
 
     SECTION 2.3.  Fractional Shares.  No scrip or fractional shares of Holdco
Stock shall be issued pursuant to the NACT Merger, and such fractional share
interests shall not entitle the owner thereof to vote or to any other rights of
a stockholder of Holdco. In lieu thereof, if any holder of NACT Stock would have
otherwise been entitled to a fractional share of Holdco Stock hereunder, then
such holder shall be entitled, after the later of the Effective Time or the
surrender of such holder's stock certificates that represent such shares of NACT
Stock to receive from Holdco cash (without interest) in an amount equal to the
product of such fractional part of a share of Holdco Stock multiplied by the
Closing Date Market Price.
 
     SECTION 2.4.  Exchange Ratio for World Access Options and World Access
Warrants.
 
     2.4.1.  As of the Effective Time, each outstanding option ("World Access
Option") and warrant ("World Access Warrant") to purchase World Access Common
Stock shall be assumed by Holdco and converted into an option or warrant, as the
case may be, to purchase shares of Holdco Common Stock, as provided below.
Following the Effective Time, each World Access Option shall continue to have,
and shall be subject to, the same terms and conditions set forth in the
applicable option plan or warrant plan (the "World Access Plans") pursuant to
which such World Access Option or World Access Warrant was granted, except that
each such World Access Option or World Access Warrant shall be exercisable for
the same number of shares of Holdco Common Stock as the number of shares of
World Access Common Stock for which such World Access Option or World Access
Warrant was exercisable immediately prior to the Effective Time.
 
     2.4.2.  As of the Effective Time, Holdco shall enter into an assumption
agreement with respect to each World Access Option and each World Access
Warrant, which shall provide for Holdco's assumption of the obligations of World
Access under the applicable World Access Plan. Prior to the Effective Time,
World Access shall make such amendments, if any, to the World Access Plans as
shall be necessary to permit such assumption in accordance with this Section
2.4.2.
 
     2.4.3.  It is the intention of the Parties that, to the extent that any
World Access Option constitutes an "incentive stock option" (within the meaning
of Section 422 of the Code) immediately prior to the Effective
 
                                      G-36
<PAGE>   487
 
Time, such World Access Option shall continue to qualify as an incentive stock
option to the maximum extent permitted by Section 422 of the Code, and that the
assumption of the World Access Option provided by this Section 2.4 shall satisfy
the conditions of Section 424(a)of the Code.
 
     SECTION 2.5.  Exchange Ratio for NACT Options.
 
     2.5.1.  As of the Effective Time, each option ("NACT Option") to purchase
NACT Common Stock then outstanding shall be assumed by Holdco and converted into
an option to purchase shares of Holdco Common Stock, as provided below.
Following the Effective Time, each NACT Option shall continue to have, and shall
be subject to, the same terms and conditions set forth in the applicable option
plan (the "NACT Plans") pursuant to which such NACT Option was granted, except
that (i) each such NACT Option shall be exercisable for that number of shares of
Holdco Stock equal to the product of (x) the number of shares of NACT Stock for
which such NACT Option was exercisable immediately prior to the Effective Time
and (y) the Exchange Ratio, rounded in the case of any NACT Option other than
any incentive stock option, up and, in the case of any incentive stock option,
down to the nearest whole share, if necessary, and (ii) the exercise price per
share of such NACT Option shall be equal to the aggregate exercise price of such
NACT Option immediately prior to the Effective Time divided by the number of
shares of Holdco Stock for which such NACT Option shall be exercisable as
determined in accordance with the preceding clause (i), rounded up to the next
highest cent, if necessary.
 
     2.5.2.  As of the Effective Time, Holdco shall enter into an assumption
agreement with respect to each NACT Option, which shall provide for Holdco's
assumption of the obligations of NACT under the applicable NACT Plan. Prior to
the Effective Time, NACT shall make such amendments, if any, to the NACT Plans
as shall be necessary to permit such assumption in accordance with this Section
2.5.2.
 
     2.5.3.  It is the intention of the Parties that, to the extent that any
NACT Option constitutes an "incentive stock option" (within the meaning of
Section 422 of the Code) immediately prior to the Effective Time, such NACT
Option shall continue to qualify as an incentive stock option to the maximum
extent permitted by Section 422 of the Code, and that the assumption of the NACT
Option provided by this Section 2.5 shall satisfy the conditions of Section
424(a) of the Code.
 
                                   ARTICLE 3.
 
                      PAYMENT OF THE MERGER CONSIDERATION
 
     SECTION 3.1.  Payment of the World Access Consideration and the NACT
Consideration.
 
     3.1.1.  At or prior to the Effective Time, Holdco shall appoint an agent
reasonably satisfactory to World Access and NACT (the "Exchange Agent") for the
purpose of exchanging certificates representing outstanding shares of World
Access Stock and NACT Stock as provided herein. As of the Effective Time, Holdco
will deposit with the Exchange Agent, in trust for the benefit of holders of
shares of World Access Stock and NACT Stock, certificates representing the
shares of Holdco Stock issuable pursuant to Section 2.1 hereof. Holdco agrees to
make available to the Exchange Agent, from time to time as needed, cash
sufficient to pay cash in lieu of fractional shares pursuant to Section 2.3
hereof.
 
     3.1.2.  As promptly as practicable after the Effective Time, the Exchange
Agent shall send or cause to be sent to each former holder of record of shares
of World Access Stock and NACT Stock transmittal materials (the "Letter of
Transmittal") for use in exchanging their certificates formerly representing
World Access Stock and NACT Stock for the Merger Consideration provided for in
this Agreement. The Letter of Transmittal will contain instructions with respect
to the surrender of certificates representing World Access Stock and NACT Stock
and the receipt of the Merger Consideration contemplated by this Agreement and
will require each holder of World Access Stock and NACT Stock to transfer good
and marketable title to such World Access Stock and NACT Stock to Holdco, free
and clear of all Liens. Upon receipt of properly completed Letters of
Transmittal, the Exchange Agent shall pay the appropriate Merger Consideration
to the stockholders of World Access and NACT, as appropriate. The Exchange Agent
shall, as promptly as practicable after the Effective Time, send or cause to be
sent to each former holder of record of World Access
 
                                      G-37
<PAGE>   488
 
Stock and NACT Stock a Letter of Transmittal and, upon the proper execution and
return of such Letter of Transmittal to the Exchange Agent, the appropriate
Merger Consideration shall be promptly paid.
 
     3.1.3.  At the Effective Time, the stock transfer books of World Access and
NACT shall be closed as to holders of World Access Stock and NACT Stock
immediately prior to the Effective Time, and no transfer of World Access Stock
and NACT Stock by any such holder shall thereafter be made or recognized and
each outstanding certificate formerly representing World Access Stock and NACT
Stock shall, without any action on the part of any holder thereof, no longer
represent World Access Stock and NACT Stock. If, after the Effective Time,
certificates are properly presented to the Exchange Agent, such certificates
shall be exchanged for the Merger Consideration contemplated by this Agreement
into which the World Access Stock and NACT Stock represented thereby were
converted in the Mergers.
 
     SECTION 3.2.  Lost Certificates.  In the event that any holder of World
Access Stock and NACT Stock is unable to deliver the certificate which
represents such holder's World Access Stock or NACT Stock, Holdco, in the
absence of actual notice that any World Access Stock or NACT Stock theretofore
represented by any such certificate has been acquired by a bona fide purchaser,
may, in its sole discretion, deliver to such holder the Merger Consideration
contemplated by this Agreement to which such holder is entitled in accordance
with the provisions of this Agreement upon the presentation of all of the
following:
 
          (a) an affidavit or other evidence to the reasonable satisfaction of
     Holdco that any such certificate has been lost, wrongfully taken or
     destroyed;
 
          (b) such security or indemnity as may be reasonably requested by
     Holdco to indemnify and hold Holdco harmless; and
 
          (c) evidence to the satisfaction of Holdco that such holder is the
     owner of World Access Stock or NACT Stock theretofore represented by each
     certificate claimed by such holder to be lost, wrongfully taken or
     destroyed and that such holder is the Person who would be entitled to
     present each such certificate for exchange pursuant to this Agreement.
 
     SECTION 3.3.  Payment to Another Person.  In the event that the delivery of
any Merger Consideration contemplated by this Agreement is to be made to a
Person other than the Person in whose name any certificate representing World
Access Stock or NACT Stock surrendered is registered, such certificate so
surrendered shall be properly endorsed (or accompanied by an appropriate
instrument of transfer), with the signature(s) appropriately guaranteed, and
otherwise in proper form for transfer, and the Person requesting such delivery
shall pay any transfer or other taxes required by reason of the delivery to a
Person other than the registered holder of such certificate surrendered or
establish to the satisfaction of Holdco that such tax has been paid or is not
applicable.
 
     SECTION 3.4.  Right to Receive the Merger Consideration Only.  Until
surrendered in accordance with the provisions of this Article 3, each
certificate representing World Access Stock and NACT Stock shall represent for
all purposes the right to receive the appropriate Merger Consideration
contemplated by this Agreement and shall not represent the right to receive any
other consideration.
 
                                   ARTICLE 4.
 
                     REPRESENTATIONS AND WARRANTIES OF NACT
 
     NACT represents and warrants to World Access that, except as set forth in
the Disclosure Schedule delivered by NACT to World Access prior hereto (the
"NACT Disclosure Schedule"), which shall identify exceptions by specific Section
references:
 
     SECTION 4.1.  Corporate Organization.  NACT has been duly organized and is

                              AFFILIATE AGREEMENT
 
WAXS Inc.
945 E. Paces Ferry Road
Suite 2240
Atlanta, Georgia 30326
 
Attention: Chief Executive Officer
 
Gentlemen:
 
     The undersigned is a stockholder of                ("Target"), a
corporation organized under the laws of the State of Delaware, and will become a
stockholder of WAXS Inc. ("Holdco") pursuant to the transactions described in
the Agreement and Plan of Merger and Reorganization, dated as of February   ,
1988 (the "Agreement"), by and among Target, Holdco and certain affiliated
parties. Under the terms of the Agreement, a subsidiary of Holdco will be merged
with and into Target (the "Merger"), with Target becoming a wholly-owned
subsidiary of Holdco, and the shares of the $.01 par value common stock of
Target ("Target Common Stock") will be converted into and exchanged for shares
of the $.01 par value common stock of Holdco ("Holdco Common Stock"). This
Affiliate Agreement represents an agreement between the undersigned and Holdco
regarding certain rights and obligations of the undersigned in connection with
the shares of Holdco Common Stock to be received by the undersigned as a result
of the Merger.
 
     In consideration of the Merger and the mutual covenants contained herein,
the undersigned and Holdco hereby agree as follows:
 
     1.  Affiliate Status.  The undersigned understands and agrees that as to
Target the undersigned is an "affiliate" under Rule 145(c) as defined in Rule
405 of the Rules and Regulations of the Securities and Exchange Commission
("SEC") promulgated under the Securities Act of 1933, as amended ("1933 Act"),
and the undersigned anticipates that the undersigned will be such an "affiliate"
at the time of the Merger.
 
     2.  Covenants and Warranties of Undersigned.  The undersigned represents,
warrants and agrees that:
 
          (a) The Holdco Common Stock received by the undersigned as a result of
     the Merger will be taken for the undersigned's own account and not for
     others, directly or indirectly, in whole or in part.
 
          (b) Holdco has informed the undersigned that any distribution by the
     undersigned of Holdco Common Stock has not been registered under the 1933
     Act and that shares of Holdco Common Stock received pursuant to the Merger
     can only be sold by the undersigned (i) following registration under the
     1933 Act, or (ii) in conformity with the volume and other requirements of
     Rule 145(d) promulgated by the SEC as the same now exist or may hereafter
     be amended, or (iii) to the extent some other exemption from registration
     under the 1933 Act might be available. The undersigned understands that
     Holdco is under no obligation to file a registration statement with the SEC
     covering the disposition of the undersigned's shares of Holdco Common
     Stock.
 
     3.  Restrictions on Transfer.
 
          (a) The undersigned understands and agrees that stop transfer
     instructions with respect to the shares of Holdco Common Stock received by
     the undersigned pursuant to the Merger will be given to Holdco's Transfer
     Agent and that there will be placed on the certificates for such shares, or
     shares issued in substitution thereof, a legend stating in substance:
 
             "The shares represented by this certificate may not be sold,
        transferred or otherwise disposed of except or unless (i) covered by an
        effective registration statement under the Securities Act of 1933, as
        amended, (ii) in accordance with (x) Rule 145(d) (in the case of shares
        issued to an individual who is not an affiliate of the issuer) or (y)
        Rule 144 (in the case of shares issued to an individual who is an
        affiliate of the issuer) of the Rules and Regulations of such Act, or
        (iii) in accordance with
 
                                      G-54
<PAGE>   505
 
        a legal opinion satisfactory to counsel for the issuer that such sale or
        transfer is otherwise exempt from the registration requirements of such
        Act."
 
          (b) Such legend will also be placed on any certificate representing
     Holdco securities issued subsequent to the original issuance of the Holdco
     Common Stock pursuant to the Merger as a result of any stock dividend,
     stock split, or other recapitalization as long as the Holdco Common Stock
     issued to the undersigned pursuant to the Merger has not been transferred
     in such manner to justify the removal of the legend therefrom. If the
     provisions of Rules 144 and 145 are amended to eliminate restrictions
     applicable to the Holdco Common Stock received by the undersigned pursuant
     to the Merger, or at the expiration of the restrictive period set forth in
     Rule 145(d), Holdco, upon the request of the undersigned, will cause the
     certificates representing the shares of Holdco Common Stock issued to the
     undersigned in connection with the Merger to be reissued free of any legend
     relating to the restrictions set forth in Rules 144 and 145(d) upon receipt
     by Holdco of an opinion of its counsel to the effect that such legend may
     be removed.
 
     4.  Understanding of Restrictions on Dispositions.  The undersigned has
carefully read the Agreement and this Affiliate Agreement and discussed their
requirements and impact upon the undersigned's ability to sell, transfer, or
otherwise dispose of the shares of Holdco Common Stock received by the
undersigned in connection with the Merger, to the extent the undersigned
believes necessary, with counsel for the undersigned or for Target.
 
     5.  Filing of Reports by Holdco.  Holdco agrees, for a period of two years
after the effective date of the Merger, to file on a timely basis all reports
required to be filed by it pursuant to Section 13 of the Securities Exchange Act
of 1934, as amended (the "1934 Act"), so that the public information provisions
of Rule 145(d) promulgated by the SEC, as the same are presently in effect, will
be available to the undersigned in the event the undersigned desires to transfer
any shares of Holdco Common Stock issued to the undersigned pursuant to the
Merger.
 
     6.  Transfer Under Rule 145(d).  If the undersigned desires to sell or
otherwise transfer the shares of Holdco Common Stock received by the undersigned
in connection with the Merger at any time during the restrictive period set
forth in Rule 145(d), the undersigned will provide the necessary representation
letter to the Transfer Agent for Holdco Common Stock, together with such
additional information as the Transfer Agent may reasonably request. If Holdco's
counsel concludes that such proposed sale or transfer complies with the
requirements of Rule 145(d), Holdco shall cause such counsel, at Holdco's
expense, to provide such opinions as may be necessary to Holdco's Transfer Agent
so that the undersigned may complete the proposed sale or transfer.
 
     7.  Acknowledgments.  The undersigned recognizes and agrees that the
foregoing provisions also apply with respect to Target Common Stock held by, and
Holdco Common Stock issued in connection with the Merger to, (a) the
undersigned's spouse, (b) any relative of the undersigned or of the
undersigned's spouse who has the same home as the undersigned, (c) any trust or
estate in which the undersigned, the undersigned's spouse, and any such relative
collectively own at least a 10% beneficial interest or of which any of the
foregoing serves as trustee, executor or in any similar capacity, and (d) any
corporation or other organization in which the undersigned, the undersigned's
spouse and any such relative collectively own at least 10% of any class of
equity securities or of the equity interest. The undersigned further recognizes
that, in the event that the undersigned is a director or executive officer of
Holdco or becomes a director or executive officer of Holdco upon consummation of
the Merger, then, among other things, any sale of Holdco Common Stock by the
undersigned within a period of less than six months following the effective time
of the Merger may subject the undersigned to liability pursuant to Section 16(b)
of the 1934 Act.
 
     8.  Miscellaneous.  This Affiliate Agreement is the complete agreement
between Holdco and the undersigned concerning the subject matter hereof. Any
notice required to be sent to any party hereunder shall be sent by registered or
certified mail, return receipt requested, using the addresses set forth herein
or such other address as shall be furnished in writing by the parties. This
Affiliate Agreement shall be governed by the laws of the State of Delaware.

FOR IMMEDIATE RELEASE
 
ATLANTA, GEORGIA -- February 25, 1998 -- WORLD ACCESS, INC. (NASDAQ: WAXS)
 
announced today that it has signed a definitive merger agreement with NACT
Telecommunications, Inc. (NASDAQ: NACT) to acquire approximately 2.7 million
shares of NACT common stock currently held by public stockholders. Pursuant to
the terms of the merger agreement, World Access will pay $17.50 per share of
NACT common stock, or approximately $46.6 million, through the issuance of new
shares of World Access common stock.
 
     The merger agreement provides that each share of NACT common stock will be
converted into shares of World Access common stock having a value of $17.50 per
share based on the average of the daily closing price of World Access common
stock as reported on the Nasdaq National Market System on each of the 20
consecutive trading days ending with the 3rd day immediately preceding the
effective time of the merger (the "Closing Price"). If the Closing Price is more
than $25.52, then each share of NACT common stock will be converted into 0.6857
shares of World Access common stock. If the Closing Price is less than $20.88
per share, then World Access may terminate the merger agreement.
 
     The merger agreement was negotiated on behalf of NACT by a Special
Committee of the NACT Board and has been approved by the Boards of Directors of
NACT and World Access. In addition, NACT has received a fairness opinion with
respect to the merger from NationsBanc Montgomery Securities LLC. The merger is
subject to, among other things, the consummation of the GST Stock Purchase,
approval of the NACT stockholders, and the satisfaction of other customary
conditions.
 
     World Access previously announced that it had entered into a definitive
agreement with GST Telecommunications, Inc. ("GST") and GST USA, Inc., a wholly
owned subsidiary of GST ("GST USA"), to acquire shares of NACT common stock held
by GST USA for $17.50 per share, or approximately $89.5 million (the "GST Stock
Purchase"). Upon completion of the GST Stock Purchase, which is currently
scheduled for early March, and the above merger transaction, World Access will
own 100% of NACT. The total consideration paid to acquire NACT will be
approximately $141 million.
 
     Steven A. Odom, Chairman and Chief Executive Officer, said "The acquisition
of NACT, which is expected to be accretive to World Access' 1998 earnings, is in
line with the Company's strategy to broaden its offering of switching, transport
and access products and fully support its customers as they build new and/or
upgrade existing telecommunications networks. NACT has been providing its
customers comprehensive telecommunications network equipment and services since
1982. It has enjoyed considerable growth and success in recent years since the
introduction of its STX tandem switch in February 1996. The STX switch, when
combined with NACT's multi-tasking billing systems, provide a turnkey package
for the emerging interexchange carrier industry. We believe that the STX switch
represents today's benchmark for the fast growing, specialty application
switching systems industry."
 
     "We are particularly pleased that Lindsay Wallace, President and Chief
Executive Officer of NACT, will continue to manage NACT as a majority owned
subsidiary of World Access. Under the leadership of Mr. Wallace, and his
outstanding team of engineering, sales and operations professionals, NACT
reported record revenues of $27.7 million and pre-tax income of $6.3 million in
its most recently completed fiscal year.

We are optimistic that World Access' financial strength, extensive customer
base, engineering capabilities and broad range of manufacturing and support
services will further support NACT's existing business and provide additional
sales and profit growth opportunities for both companies."

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                 MARCH 31, 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 for 67.3% ownership in NACT Telecommunications, Inc.
("NACT"). 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 months ended March 31, 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 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
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. These shares had an initial fair value of 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.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     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 the net assets acquired and to approximately $66.5 million
of purchased in-process R&D. The excess of purchase price over 67.3% of the fair
value of net assets acquired and purchased in-

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
process R&D, currently estimated at approximately $40.8 million, has been
recorded as goodwill and is being amortized over a 20 year period.
 
     During the first quarter of 1998, 67.3%, or $44.6 million, of purchased
in-process R&D, which consists 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 the 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 three months ended March 31, 1998
and 1997 would have been approximately $38,893,000 and $32,220,000; $1,129,000
and $3,699,000; $42,000 and $2,244,000; and $0.12 and $0.0, 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. In addition, the portion of the purchase price allocated to
in-process R&D expensed in accordance with applicable accounting rules of $50.0
million will not recur, therefore, the pro forma results have been prepared
excluding this charge.

     Goodwill is being amortized on a straight-line basis over a 15 to 20 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.
 
NOTE 5.  DEBT
 
     The Company has a $10.0 million revolving line of credit with a large
European bank. As of March 31, 1998, the Company had borrowings of $1.8 million
outstanding under this facility. These borrowing were repaid to the bank in
April 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 are being 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

     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 March
31, 1998, approximately $1.8 million of accrued special charges is included in
Other current liabilities on the Company's March 31, 1998 balance sheet. 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 921,166
were included in computing diluted earnings per share for the first quarter of
1997. A total of 1,204,000 and 1,246,000 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 March 31, 1998 and
1997, respectively, because the conditions for release of shares from escrow had
not been satisfied.

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"). The initial complaint further alleged defamation and unfair
competition as a result of a communication disseminated by NACT to its customers
and tortious interference with prospective business relations, alleging that
NACT induced third parties to abandon licensing negotiations with Aerotel.
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.
 
     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 with respect to the settlement of this
action, and 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 March 31, 1998.
 
     Management expects a final Aerotel settlement agreement to be executed in
the near future. If a settlement does not occur, NACT's patent counsel believes
that NACT has valid defenses to the Aerotel claims (which, if upheld, would be
valid for all defendants), and the defendants intend to vigorously defend.
However, no assurances can be given as to the outcome of this action. An
unfavorable decision in this action, however, could have a material adverse
effect on the Company's business, financial condition and results of operations.
 
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

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
Bankruptcy Court. The transactions, which will be accounted for under the
purchase method of accounting, are currently expected to close in August 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. Upon completion
of the Resurgens acquisition, WorldCom is expected to own approximately 15% of
Company on a fully diluted basis.
 
NOTE 10.  COMPREHENSIVE INCOME.
 
     The Company adopted Statement of Financial Accounting Standards No. 130
("SFAS 130"), "Reporting Comprehensive Income", effective January 1, 1998. For
the three months ended March 31, 1998 and 1997, respectively, comprehensive and
net income were the same for the Company.

ITEM 2 -- MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS
 
  Disclosure Regarding Forward-Looking Statements
 
     Under the Private Securities Litigation Reform Act of 1995, companies are
provided a "safe harbor" for making forward-looking statements about the
potential risks and rewards of their strategies. The Company believes that it is
in the best interest of its stockholders to use these provisions in discussing
future events in this Form 10-Q and other communications. These forward-looking
statements include the Company's plans for growth, the potential for
development, acceptance of the Company's products and other factors that could
affect the Company's future operations or financial position.
 
     The Company's ability to achieve its goals depends on many known and
unknown risks and uncertainties, as well as changes in general economic and
business conditions. These factors could cause the anticipated performance and
results of the Company to differ materially from those described or implied in
such forward-looking statements.
 
     Factors that could cause or contribute to such differences include the
risks and uncertainties described in the Company's SEC reports, including the
Company's Annual Report on Form 10-K, as amended, for the year ended December
31, 1997 and the Company's Registration Statement on Form S-3 (No. 333-43497).
 
  Overview
 
     The Company develops, manufactures and markets wireline and wireless
switching, transport and access products for the global telecommunications
markets. The products offered by the Company include those manufactured by the
Company as well as those manufactured by other telecommunications equipment
manufacturers. 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.
 
     During 1995 and 1996, the Company completed strategic and financial
restructuring programs to strengthen its management team, reposition the Company
as a provider of telecommunications products, improve its financial condition,
reduce its operating costs and position the Company for future growth. These
programs were undertaken following the significant losses incurred by the
Company in the early 1990s, primarily due to a discontinued smart pay telephone
business, and to take advantage of the significant growth opportunities within
the Company's existing customer base and related markets. In November 1994, the
Company began to rebuild its management team and change its strategic focus. The
Company 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 the Company, have brought significant
experience in manufacturing and marketing telecommunications equipment to the
Company.
 
     The Company 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, the Company acquired AIT, Inc. ("AIT"), a full service provider of
Northern Telecom switching systems, add-on frames and related circuit boards;
effective October 1995, the Company acquired Westec Communications, Inc.
("Westec"), a provider of wireless products and services primarily to the cable
television industry; effective January 1996, the Company acquired Sunrise
Sierra, Inc. ("Sunrise"), a developer and manufacturer of intelligent transport
and access products; effective January 1997, the Company acquired Cellular
Infrastructure Supply, Inc. ("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, the Company
acquired Galaxy Personal Communication Services ("Galaxy"), a RF engineering
firm that provide 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 the Company's
traditional telephone service provider and private network operator markets.
 
     In the first quarter of 1998, the Company 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
 
                                      I-11
<PAGE>   527
 
advanced telecommunications switching platforms with integrated applications
software. In May 1998, the Company signed definitive agreements to acquire
Resurgens, a facilities-based provider of international network access, commonly
referred to in the industry as carriers' carrier. These acquisitions have
positioned the Company to offer its customers a complete telecommunications
network solution, including proprietary equipment, planning and engineering
services and access to international long distance.
 
     The Company realized significant improvements in its sales and operating
results since 1994 as a result of the acquisitions and internal growth
initiatives. The Company's total sales increased by 82.3% in 1997, 69.2% in 1996
and 97.2% in 1995. Total sales for the first quarter of 1998 increased by 68.0%
over the fourth quarter of 1997. As the Company increased its product sales from
18.2% of total sales in 1994 to 79.0% of total sales in the first quarter 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 41.7% in the first
quarter of 1998. As a percentage of total sales, the Company's 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 27.9% in the first quarter of 1998. The Company
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 the Company has aggressively pursued acquisitions in recent years,
over 60 percent of the Company's total sales growth since 1994 has come from
internal growth initiatives. The Company has had considerable success in growing
businesses post acquisition, most notably AIT and CIS, as a result of its
ability to provide working capital, an extensive base of telecommunications
customers and a broad range of support services.
 
     Since January 1, 1995, the Company 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, proceeds from stock warrant and option exercises, and a five-year
$10.0 million credit facility. The Company has used this capital for
acquisitions and to support the working capital requirements associated with the
Company's growth. The Company's working capital and stockholders' equity have
increased from $2.3 million and $1.2 million, respectively, at December 31, 1994
to $118.2 million and $89.1 million, respectively, at March 31, 1998.
 
  Fluctuations in Quarterly Operating Results
 
     The Company's operating results have fluctuated significantly in the past.
As the Company increases its number of telecommunications product offerings, its
future operating results may vary significantly depending on factors such as the
timing and shipment of significant orders, new product offerings by the Company
and its competitors, market acceptance of new and enhanced versions of the
Company's products, changes in pricing policies by the Company and its
competitors, the availability of new technologies, the mix of distribution
channels through which the Company's products are sold, the inability to obtain
sufficient supplies of sole or limited source components for the Company's
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.
 
     The Company's sales during the first three months of 1998 included
approximately $13.5 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 the Company to the risk of
revenue fluctuations in the event that customers adjust the timing of their
orders.

  Three Months Ended March 31, 1998 Compared to Three Months Ended March 31,
1997
 
     Sales.  Total sales increased $15.5 million, or 76.4%, to $35.7 million in
the first quarter of 1998 from $20.3 million in the first quarter of 1997.
Product sales increased to 79.0% of total sales in the first quarter of 1998
from 76.4% in the first quarter of 1997.
 
     Product sales increased $12.8 million, or 82.5%, to $28.2 million in the
first quarter of 1998 from $15.5 million in the first quarter of 1997. The
increase related to sales generated by NACT and ATI, which were acquired
effective March 1, 1998 and February 1, 1998, respectively, and an increase of
mobile network equipment sold by CIS.
 
     Service revenues increased $2.7 million, or 56.9%, to $7.5 million in the
first quarter of 1998 from $4.8 million in the first quarter of 1997. The
increase related to engineering services performed by Galaxy, which was acquired
effective July 1, 1997, and additional pay telephone refurbishment revenues.
 
     Gross Profit.  Gross profit increased $5.3 million, or 86.0%, to $11.5
million in the first quarter of 1998 from $6.2 million in the first quarter of
1997. Gross profit margin increased to 32.3% in the first quarter of 1998 from
30.6% in the first quarter of 1997. Gross profit margin excluding the special
charge of approximately $3.4 million (see Note 6 to "Financial Statements") was
41.7% in the first quarter of 1998. The improved
 
                                      I-13
<PAGE>   529
 
performance resulted from economies of scale associated with the 76.4% 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 40.6% in the first
quarter of 1998 from 35.6% in the first quarter of 1997. Gross profit margin
excluding the special charge was 45.3% in the first quarter of 1998. The
improved margins related to the NACT and ATI sales of proprietary equipment and
systems and the increase in sales of CIS mobile network equipment, all of which
generally carry margins in excess of 40.0%. The Company's switching products
experienced declines in gross margin during the first 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 was 1.0% in the first quarter of
1998 as compared to 14.6% in the first quarter of 1997. Gross profit margin
excluding the special charge was 28.1% in the first quarter of 1998. The
improvement was due to the addition of consulting revenues from Galaxy, which
was acquired effective July 1, 1997, and improved margins on pay telephone
refurbishment revenues.
 
     Engineering and Development.  Engineering and development expenses
increased $472,000, or 149.1%, to $788,000 in the first quarter of 1998 from
$316,000 in the first quarter of 1997. The increase in expenses was attributable
to the acquisitions of NACT and ATI and the continued expansion of the Company's
development group. Engineering and development expenses increased to 2.2% of
total sales in the first quarter of 1998 from 1.6% of total sales in the first
quarter of 1997.
 
     Selling, General and Administrative Expenses.  Selling, general and
administrative expenses increased $1.3 million, or 69.8%, to $3.3 million in the
first quarter of 1998 from $1.9 million in the first quarter of 1997. The
increase related primarily to expenses associated with the operations of NACT,
ATI and Galaxy, which were acquired subsequent to the first quarter of 1997. As
a percentage of total sales, selling, general and administrative expenses
decreased to 9.1% in the first quarter of 1998 from 9.5% in the first quarter of
1997.
 
     Amortization of Goodwill.  Amortization of goodwill increased $580,000 to
$864,000 in the first quarter of 1998 from $284,000 in the first quarter of
1997, primarily as a result of goodwill recorded in 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 $6.3 million, or 171.3%, to $10.0 million in the first quarter
of 1998 from $3.7 million in the first quarter of 1997. Operating income margin
increased to 27.9% in the first quarter of 1998 from 18.2% in the first quarter
of 1997.
 
     Interest and Other Income.  Interest and other income increased $902,000 to
$1.3 million in the first quarter of 1998 from $367,000 in the first quarter of
1997 due to a significant increase in invested cash balances of the Company,
resulting primarily from the sale of $115.0 million convertible subordinated
notes in October 1997.
 
     Interest and Other Expense.  Interest expense increased to $1.5 million in
the first quarter of 1998 from $29,000 in the first quarter of 1997. The
increase is primarily due to the interest recorded on the $115.0 million
convertible subordinated notes sold in October 1997, which bear interest at 4.5%
and the related debt issuance cost amortization.
 
     Income Taxes.  The Company's effective income tax rate increased to 40.0%
in the first quarter of 1998 from 35.0% in the first quarter of 1997. The
Company's 1998 effective rate is unfavorably impacted by the significant
increase in non-deductible goodwill amortization resulting from acquisitions.
 
  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 ATI and a 67.3% interest in NACT (see Note 2 to the "Financial
Statements"). 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. The Company expects to record an
                                      I-14
<PAGE>   530
 
additional in-process research and development charge of approximately $22.0
million in the third 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 include
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 other 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. Product is 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
Compact:                                      95.0% of units in development
QAM:                                         100.0% of units in development
</TABLE>
 
     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.
 
                                      I-15
<PAGE>   531
 
     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, the Company's senior management decided that the following
actions were necessary to streamline operations and position the Company 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 the 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 Westee 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 the Company, e.g., relocation of existing employees,
recruiting and training of new employees and facility start-up costs. The
special charge consisted of:

Obsolete and redundant inventories..........................  $3,360,000

                                                              $6,600,000
                                                              ==========
</TABLE>
 
     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 the
Company's 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 the Company 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 Report, the Company 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 the Company 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 March
31, 1998, approximately

$1.8 million of accrued special charges is included in Other current liabilities
on the Company's March 31, 1998 balance sheet.
 
  Liquidity and Capital Resources
 
     Overview.  Cash management is a key element of the Company's 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 March 31, 1998, the Company had $63.3
million of cash and equivalents and $8.2 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 $2.0
million in the first quarter of 1998 as compared to cash used by operations of
$1.3 million in the first quarter of 1997.
 
     Accounts receivable increased $19.4 million, or 95.8%, to $39.7 million at
March 31, 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 the Company
(first quarter 1998 sales were $35.7 million as compared to fourth quarter 1997
sales of $21.3 million). Average days sales outstanding at March 31, 1998 were
approximately 90 days as compared to 81 days at December 31, 1997.
 
     Inventories increased $5.9 million, or 26.4%, to $28.3 million at March 31,
1998 from $22.4 million at December 31, 1997. This increase was due to the
acquisitions of NACT and ATI and the planned build-up of CDX switching and
WX-5501 inventories related to the closure of the Company's Orlando
manufacturing facility. 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 Note 6 to "Financial
Statements").
 
     Investing Activities.  Cash used by investing activities, primarily for the
acquisitions of businesses, was $59.3 million and $4.2 million for the first
quarters of 1998 and 1997, respectively.
 
     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 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 the Company's common stock. These shares had an
initial fair value of approximately $26.9 million. This transaction increased
the Company's ownership of NACT to 67.3%.
 
     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 then 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. This merger is expected to be consummated in July 1998.
 
     On December 24, 1997, the Company 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 the Company's 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 the Company's common stock. These shares
were immediately placed into escrow and will be
 
                                      I-17
<PAGE>   533
 
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. 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 the Company's December 31, 1997 balance sheet.
During the first quarter of 1998, the note receivable was included in the
Company's purchase price of ATI.
 
     During the first quarter of 1998 and 1997, the Company invested $1.9
million and $726,000, respectively, in capital expenditures. These expenditures
were primarily for new manufacturing and test equipment, computer network and
related communications equipment designed to upgrade the Company's management
information systems and facilitate the integration of acquisitions, and facility
improvements required in connection with the Company's growth.
 
     Financing Activities.  Cash provided from financing activities was $2.5
million and $4.5 million for the first quarter of 1998 and 1997, respectively.
 
     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 initial purchasers' discount fees of $3.0
million.
 
     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 $14.6 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 $3.2 million, net of amortization, are included in Other
assets on the Company's March 31, 1998 balance sheet.
 
     As of March 31, 1998 and 1997, the Company had borrowings of $1.8 million
and $4.5 million, respectively, outstanding under its $10.0 revolving line of
credit. Borrowings under the Company's line of credit 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. As of the date of this
Report, there were no amounts outstanding under the Company's line of credit.
 
     During the first quarter of 1998, the Company received approximately $4.4
million in cash, including related federal income tax benefits, from the
exercises of incentive and non-qualified stock options and warrants by the
Company's directors and employees.
 
     Income Taxes.  As a result of the exercises of non-qualified stock options
and warrants by the Company's directors and employees, the Company has realized
a federal income tax benefit of approximately $2.7 million for the first quarter
of 1998. Although this tax benefit does not have any effect on the Company's
provision for income tax expense for 1998, it represents a significant cash
benefit to the Company. 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.  The Company's 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. As of the date of this Report,
the Company has approximately $60.0 million of cash and a $10.0 million
revolving line of credit available. The Company believes that existing cash
balances, available borrowings under the Company's
                                      I-18
<PAGE>   534
 
line of credit and cash projected to be generated from operations will provide
the Company 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 the Company's computer
systems that have date sensitive software may recognize a date using "00" as the
year 1900 rather than the year 2000 (the so-called "Year 2000 Issue"). This
could result in a system failure or miscalculations causing disruptions,
including, among other things, a temporary inability to process transactions,
send invoices or engage in normal business activities.
 
     The Company 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 the
Company's computer systems have been put into service within the last several
years, the Company does not expect any such modifications to have a material
adverse effect on the Company's consolidated results of operations, liquidity
and capital resources.
 
     In addition, the Company is in the process of developing a plan whereby it
will review the year 2000 readiness of its customers and suppliers. In doing so,
the Company will undertake appropriate internal reviews and will contact certain
of its significant customers to assess, to the extent possible, Year 2000 Issues
related to the Company's products. In that regard, the Company has identified
that certain of its products, including NACT's NTS 1000 billing System, are not
year 2000 compliant. The Company is in the process of releasing new versions of
such products and making necessary modifications to existing products to address
the Year 2000 Issue. These new and revised products are expected to be available
commencing in the first quarter of 1999. The Company expects that many of its
customers will upgrade to the new products. However, there can be no assurance
that the Company's customers will upgrade to the new year 2000 compliant
products or that the modifications planned to certain of the existing products
will be successful or completed in a timely manner. Although, the Company
believes that it can address year 2000 readiness issues related to products,
there may still be disruptions and or product failures that are unforeseen.
 
     The Company 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 the Company will function properly or be available without
interruption in the year 2000. Nevertheless, it will be impossible for the
Company 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, the Company
also intends to develop a business continuity plan to minimize the impact of
such external events.
 
     While the Company's efforts to address year 2000 issues will involve
additional costs and the time and effort of a number of Company employees, the
Company believes, based on currently available information, that it will be able
to manage its total year 2000 exposure.
 
     There can be no assurance, however, that the Company 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 the Company's
systems, would not have a material adverse effect on the Company's consolidated
results of operations, liquidity and capital resources.

ITEM 2.  CHANGES IN SECURITIES
 
     On January 29, 1998, the Company completed the acquisition of Advanced
TechCom, Inc., a Delaware corporation ("ATI"), pursuant to that certain
Agreement and Plan of Merger dated as of December 24, 1998 by and among the
Company, ATI, Cellular Infrastructure Supply, Inc., a Delaware corporation and a
wholly-owned subsidiary of the Company, and Ernest H. Lin (the "Merger
Agreement"). Pursuant to the Merger Agreement, (i) the issued and outstanding
shares of ATI's Series A Preferred Convertible Preferred Stock, $.10 par value
per share (the "ATI Preferred Stock"), were converted into the right to receive
(the "Merger Stock Consideration") an aggregate of 424,932 shares of the
Company's common stock, $.01 par value (the "Common Stock"); (ii) holders of the
issued and outstanding shares of ATI's common stock, $.10 par value, were given
a choice to convert their ATI common stock into ATI Preferred Stock on a
one-for-one basis and thereupon receive the Merger Stock Consideration to the
same extent as holders of ATI Preferred Stock or (b) receive $.01 in cash for
each share of ATI common stock not so converted; and (iii) except for Dr. Lin,
who received cash and shares of Common Stock, each holder of an option to
acquire ATI common stock that was vested as of December 31, 1997 was paid cash
in the amount equal to the difference (if any) between $1.00 and the exercise
price of such ATI option multiplied by the number shares of ATI common stock
underlying such option.
 
     In addition, the persons entitled to receive the Merger Stock Consideration
are also entitled to receive up to an aggregate of 209,050 shares of Common
Stock payable upon the achievement of certain earnings targets during 1998 and
1999 (the "Contingent Merger Stock"). The Contingent Merger Stock has been
issued and placed into escrow pending its release to the persons entitled to
receive the Merger Stock Consideration.
 
     The sale of the shares of Common Stock issued in connection with the Merger
Agreement was not registered under the Securities Act of 1933, as amended (the
"Securities Act"), in reliance on the exemption provided by Section 4(2) of the
Securities Act.
 
     On February 27, 1998, the Company completed the acquisition (the "NACT
Stock Acquisition") of 5,113,712 shares of the common stock of NACT
Telecommunications, Inc. from GST Telecommunications, Inc., a federally
chartered Canadian corporation ("GST"), and GST USA, Inc., a Delaware
corporation and a wholly-owned subsidiary of GST ("GST USA"), pursuant to that
certain Stock Purchase Agreement by and between the Company, GST and GST USA
dated as of December 31, 1997. In connection with the NACT Stock Acquisition,
the Company issued to GST USA 1,429,907 shares of Common Stock. The sale of the
shares of Common Stock issued in connection with the NACT Stock Acquisition was
not registered under the Securities Act in reliance on the exemption provided by
Section 4(2) of the Securities Act.

ITEM 5.  OTHER EVENTS.
 
     On May 12, 1998, World Access, Inc. (the "Company") announced that it had
entered into (i) a definitive Agreement and Plan of Merger and Reorganization
(the "Merger Agreement") with Cherry Communications Incorporated (d/b/a
Resurgens Communications Group) ("RCG") pursuant to which the Company will
acquire RCG in a merger transaction (the "Merger"), and (ii) a Share Exchange
Agreement and Plan of Reorganization (the "Exchange Agreement") with the sole
shareholder (the "Shareholder") of Cherry Communications U.K. Limited ("Cherry
U.K.") pursuant to which the Company will acquire Cherry U.K. in a share
exchange transaction (the "Exchange").
 
     In connection with the Merger, the creditors of RCG will receive an
aggregate of 9,375,000 shares of common stock of WAXS INC. ("New World Access").
New World Access is a wholly-owned subsidiary of the Company that will become
the parent of the Company upon the completion of the previously reported
acquisition of the shares of NACT Telecommunications, Inc. not already owned by
the Company and the holding company reorganization to be effective in connection
therewith (the "Holding Company Reorganization"). Of the shares of New World
Access common stock to be issued to the RCG creditors, two-thirds will be held
in escrow and will be released to the RCG creditors over the two and one-half
years following the consummation of the Merger subject to the attainment of
certain earnings levels for the combined business of RCG and Cherry U.K.
 
     In connection with the Exchange, the Shareholder will receive an aggregate
of 1,875,000 shares of New World Access common stock, of which one-third will be
issued to the Shareholder at closing and the remaining two-thirds will be issued
and held in escrow and will be released to the Shareholder over the two and
one-half year period following the consummation of the Exchange subject to the
attainment of certain earnings levels for the combined business of RCG and
Cherry U.K. The Exchange Agreement provides, however, that the number of shares
of New World Access common stock to be received by the Shareholder will be
reduced to the extent that New 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 New World Access, into options to acquire New World
Access common stock.
 
     Each of the Merger and the Exchange is subject to the satisfaction of
certain conditions customary in similar transactions, including the approval of
the Company's stockholders and the consummation of the Holding Company
Reorganization. The consummation of the Merger is also subject to the Bankruptcy
Court's approval and confirmation of RCG's Plan of Reorganization which is
expected to be filed by June 5, 1998. In addition, the Merger Agreement is
subject to the approval of the Bankruptcy Court. Finally, the consummation of
the Merger is a condition to the consummation of the Exchange, and the Exchange
is a condition to the consummation of the Merger.
 
     The foregoing description of the Merger and the Exchange is qualified in
its entirety by reference to the Merger Agreement and the Exchange Agreement
which are filed as exhibits herewith.

</TABLE>
 
     Notwithstanding the foregoing, if the Closing Date is (a) on or after July
15, 1998 but prior to August 16, 1998, then the First Performance Period shall

1998 and the Target EBITDA with respect thereto shall be reduced to $7,100,000,
(b) on or after August 16, 1998 but prior to September 30, 1998, then the First

Corporation and Cherry U.K. is less than the Target EBITDA required for the
release of Contingent Payment Stock in either of the First or Second Performance

zero), then, notwithstanding the table above, the Contingent Payment Stock shall

Cherry U.K. for such Performance Period and any subsequent Performance Periods
equals or exceeds the cumulative Target EBITDA for such Performance Periods.
 
     SECTION 6.3.  Accelerated Release.  Notwithstanding anything to the
contrary, (a) if during any calendar quarter of the Second Performance Period,
the closing price per share of the New World Access 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 Contingent Payment Stock
shall be released on February 15, 2000, provided that if no shares of Contingent
Payment Stock are eligible for release during any such calendar quarter, then
such shares of Contingent Payment Stock shall become eligible for release in a
subsequent calendar quarter of the Second Performance Period if the closing
price per share of the New World Access 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

beginning with the calendar quarter for which such shares of Contingent Payment
Stock were not eligible for release; (b) if the combined EBITDA for the
Surviving Corporation and Cherry U.K. for the Second Performance Period equals

Change of Control (except to the extent that the ability to earn such shares has
been lost under this Article 6) and the restrictions set forth in Section 6.4
shall not apply.
 
     Section 6.4 Transfer Restrictions. Notwithstanding anything to the contrary
contained herein, (a) no holder of Disbursed Stock may, until the 365th day

                       REPRESENTATIONS AND WARRANTIES OF
                 WORLD ACCESS, NEW WORLD ACCESS AND MERGER SUB
 
     In order to induce RCG to enter into this Agreement, World Access, New
World Access and Merger Sub, jointly and severally, represent and warrant to RCG
that, except as set forth in the World Access SEC Documents or the Disclosure
Schedule to be delivered by World Access to RCG within ten (10) Business Days of
the date hereof (the "World Access Disclosure Schedule"), which World Access
Disclosure Schedule shall identify exceptions by specific Section references:
 
     SECTION 7.1.  Organization, Qualification, and Corporate Power.  Each of
World Access and its Subsidiaries is a corporation duly organized, validly
existing, and in good standing under the laws of the jurisdiction of its
incorporation. Each of World Access and its Subsidiaries is duly authorized and
qualified to conduct business and is in good standing under the laws of each
jurisdiction where such qualification is required, except where the lack of such
qualification would not have a World Access Material Adverse Effect. Each of
World Access and its Subsidiaries has full corporate power and authority to
carry on the businesses in which it is engaged and to own, lease, use and
operate the properties owned, leased used and operated by it. The copies of the
Certificate of Incorporation and the Bylaws of World Access and the equivalent
organizational documents of each of its Subsidiaries, which have previously been
made available to RCG, are true, complete and correct copies of such documents
as in effect as of the date of this Agreement.
 
     SECTION 7.2.  Capitalization.  The entire authorized common capital stock
of World Access consists of 40,000,000 shares of World Access Stock, of which
21,848,701 shares were issued and outstanding as of May 8, 1998. The entire
authorized common capital stock of New World Access consists of 40,000,000

have been duly authorized and are validly issued, fully paid, and nonassessable.
Except as disclosed in the World Access SEC Documents, there are no outstanding
or authorized options, warrants, purchase rights, subscription rights,
conversion rights, exchange rights, or other contracts or commitments that could
require World Access or any of its Subsidiaries to issue, sell, or otherwise
cause to become outstanding any of its capital stock. There are no outstanding
or authorized stock appreciation, phantom stock, profit participation, or
similar rights with respect to World Access and its Subsidiaries. World Access
and its Subsidiaries have no outstanding bonds, debentures, notes or similar
obligations the holders of which have the right to vote generally with holders
of World Access Stock or New World Access Stock.
 
     SECTION 7.3.  Non-contravention.  Neither the execution and the delivery of
this Agreement, nor the consummation of the transactions contemplated hereby,
will (a) violate any constitution, statute, regulation, rule, injunction,
judgment, order, decree, ruling, charge, or other restriction of any government,
governmental agency, or court to which World Access or any of its Subsidiaries
is subject or any provision of the charter or bylaws of any of World Access or
any of its Subsidiaries; or (b) except with respect to those
 
                                      J-21

agreements for which Consent shall be obtained prior to Closing, conflict with,
result in a breach of, constitute a default under, result in the acceleration
of, create in any party the right to accelerate, terminate, modify, or cancel,
or require any notice under any agreement, contract, lease, license, instrument,
or other arrangement to which World Access or any of its Subsidiaries is a party
or by which it is bound or to which any of its assets is subject (or result in
the imposition of any Security Interest upon any of its assets), except where
the violation, conflict, breach, default, acceleration, termination,
modification, cancellation, failure to give notice, or Security Interest would
not have a World Access Material Adverse Effect. Except for Consents required
under or in relation to the (a) HSR Act, (b) the Communications Act and any
rates, regulations, practices and policies of the FCC, (b) state securities or
"blue sky" laws, (d) the Securities Act, (e) the Exchange Act, (f) the IBCA with
respect to the filing of the Articles of Merger, (g) laws, rules, regulations,
practices and orders of any PUC, foreign telecommunications regulatory agencies
or similar state or foreign regulatory bodies, (h) rules and regulations of
NASDAQ, and (i) such Consents and filings the failure of which to make or obtain
would not have a World Access Material Adverse Effect, neither World Access nor
any of its Subsidiaries is required to give any notice to, make any filing with,
or obtain any Consent of any Regulatory Authority in order for the Parties to
consummate the transactions contemplated by this Agreement. All consents,
approvals, orders, authorizations, registrations, declarations and filings
required under or in relation to any of the foregoing clauses (a) through (h)
are hereinafter referred to collectively as the "Required Consents."
 
     SECTION 7.4.  Brokers' Fees.  None of World Access or any of its

Robinson-Humphrey Company, Inc., whose fees and expenses will be paid by World
Access in accordance with its agreement with such firm based upon arrangements
made by or on behalf of World Access and previously disclosed to RCG.
 
     SECTION 7.5.  World Access SEC Documents.  Each of World Access and its
Subsidiaries has timely filed with the SEC all forms, reports, schedules,
statements, exhibits and other documents required to be filed by it since
December 31, 1995 with the SEC (such documents, as supplemented and amended
since the time of filing, collectively, the "World Access SEC Documents"). The
World Access SEC Documents, including any financial statements or schedules
included therein, at the time filed (and, in the case of registration statements
and proxy statements, on the dates of effectiveness and the dates of mailing,
respectively) (a) did not contain any untrue statement of a material fact or
omit to state a material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which
they were made, not misleading, and (b) complied in all material respects with
the applicable requirements of the Exchange Act and the Securities Act, as the
case may be. The consolidated financial statements (including the related notes)
of World Access included in the World Access SEC Documents comply as to form in
all material respects with applicable accounting requirements and the published
rules and regulations of the SEC with respect thereto, were prepared in
accordance with GAAP (except, in the case of unaudited statements, as permitted
by Form 10-Q of the SEC) applied on a consistent basis during the periods
involved (except as may be indicated in the notes thereto), and fairly present
(subject in the case of unaudited statements to the absence of footnotes and to
normal, recurring and year-end audit adjustments which will not be material
individually or in the aggregate) the consolidated financial position of World
Access as of the dates thereof and the consolidated results of its operations
and cash flows for the periods then ended.

World Access Material Adverse Effect. Without limiting the generality of the
foregoing, since that date:

     borrowed money and capitalized lease obligations;
 
          (h) other than is normal and customary with respect to their

          (k) none of World Access or any of its Subsidiaries has declared, set

     employees outside the Ordinary Course of Business;
 
          (p) none of World Access or any of its Subsidiaries has adopted,
     amended, modified, or terminated any bonus, profit-sharing, incentive,

view, to World Access.
 
     SECTION 7.9.  Litigation.  Neither World Access nor any of its Subsidiaries
(a) is subject to any outstanding injunction, judgment, order, decree, ruling,
or charge or (b) is a party or, to the Knowledge of World Access, is threatened

     In order to induce World Access to enter into this Agreement, RCG
represents and warrants to World Access and New World Access that, except as set
forth in the Disclosure Schedule to be delivered by RCG to World Access within
ten (10) Business Days of the date hereof (the "RCG Disclosure Schedule"), which
shall identify exceptions by specific Section references:
 
     SECTION 8.1.  Organization, Qualification, and Corporate Power.  Each of
RCG and its Subsidiaries is a corporation duly organized, validly existing, and
in good standing under the laws of the jurisdiction of its incorporation. Each
of RCG and its Subsidiaries is duly authorized and qualified to conduct business
and is in good standing under the laws of each jurisdiction where such
qualification is required, except where the lack of such qualification would not
have an RCG Material Adverse Effect. Each of RCG and its Subsidiaries has full
corporate power and authority to carry on the businesses in which it is engaged
and to own, lease, use, and operate the properties owned, leased, used, and
operated by it. The copies of the articles of incorporation and the bylaws of
RCG and the equivalent organizational documents of each of its Subsidiaries,
which have previously been made available to World Access, are true, complete
and correct copies of such documents as in effect as of the date of this
Agreement.
 
     SECTION 8.2.  Capitalization.  The entire authorized common capital stock
of RCG consists of 10,000 shares of RCG Stock, of which 1,249 shares of RCG
Stock are issued and outstanding. No shares of RCG Stock are held in treasury.
All of the issued and outstanding shares of RCG Stock have been duly authorized
and are validly issued, fully paid, and nonassessable. There are no outstanding
or authorized options, warrants, purchase rights, subscription rights,
conversion rights, exchange rights, or other contracts or commitments that could
require RCG or any of its Subsidiaries to issue, sell, or otherwise cause to
become outstanding any of its capital stock. There are no outstanding or
authorized stock appreciation, phantom stock, profit participation, or similar
rights with respect to RCG and its Subsidiaries. RCG and its Subsidiaries have
no outstanding bonds, debentures, notes or other similar obligations the holders
of which have the right to vote generally with holders of RCG Stock.
 
     SECTION 8.3.  Non-contravention.  Subject to Applicable Bankruptcy Law and
to the entry of the Order by the Bankruptcy Court, neither the execution and the
delivery of this Agreement, nor the consummation of the transactions
contemplated hereby, will (a) violate any constitution, statute, regulation,
rule, injunction, judgment, order, decree, ruling, charge, or other restriction
of any government, governmental agency, or court to which any of RCG is subject
or any provision of the charter or bylaws of RCG or any of its Subsidiaries; or
(b) except with respect to those agreements for which Consent shall be obtained
prior to
                                      J-24

Closing, conflict with, result in a breach of, constitute a default under,
result in the acceleration of, create in any party the right to accelerate,
terminate, modify, or cancel, or require any notice under any agreement,
contract, lease, license, instrument, or other arrangement to which RCG or any
of its Subsidiaries is a party or by which it is bound or to which any of its
assets is subject (or result in the imposition of any Security Interest upon any
of its assets), except where the violation, conflict, breach, default,
acceleration, termination, modification, cancellation, failure to give notice,
or Security Interest would not have an RCG Material Adverse Effect. Except as
required by Applicable Bankruptcy Law and except for the Required Consents and
such Consents and filings the failure of which to make or obtain would have an
RCG Material Adverse Effect, neither RCG nor any of its Subsidiaries is required
to give any notice to, make any filing with, or obtain any Consent of any
Regulatory Authority in order for the Parties to consummate the transactions
contemplated by this Agreement.
 
     SECTION 8.4.  Brokers' Fees.  RCG has no liability or obligation,
contingent or otherwise, to pay any fees or commissions or similar payments to
any broker, finder, or agent with respect to the transactions contemplated by
this Agreement.
 
     SECTION 8.5.  Title to Assets.  Each of RCG and its Subsidiaries has good
and marketable title to all of its material properties and assets, real and
personal, tangible and intangible, used by it, located on its premises, or shown
on the RCG Most Recent Balance Sheet or acquired after the date thereof, free
and clear of all Security Interests, except for properties and assets disposed
of in the Ordinary Course of Business since the date of the RCG Most Recent
Balance Sheet. All leases pursuant to which RCG or any of its Subsidiaries
leases from other Persons material amounts of real or personal property are in
good standing, valid and effective in accordance with their respective terms,
and there is not, to the Knowledge of RCG, under any of such leases, any
existing material default or event of default (or event which, with notice or
lapse of time, or both, would constitute a material default) except where lack
of such good standing, validity and effectiveness or the existence of such
default or event of default would not reasonably be expected to have an RCG
Material Adverse Effect.
 
     SECTION 8.6.  Subsidiaries.  The RCG Disclosure Schedule sets forth for
each Subsidiary of RCG (a) its name and jurisdiction of incorporation, (b) the
number of shares of authorized capital stock of each class of its capital stock,
(c) the number of issued and outstanding shares of each class of its capital
stock, the names of the holders thereof, and the number of shares held by each
such holder, and (d) the number of shares of its capital stock held in treasury.
All of the issued and outstanding shares of capital stock of each Subsidiary of
RCG have been duly authorized and are validly issued, fully paid, and
nonassessable and were issued in accordance with applicable federal and state
securities laws. RCG holds of record and owns beneficially all of the
outstanding shares of each Subsidiary of RCG, free and clear of any restrictions
on transfer (other than restrictions under the Securities Act and state
securities laws), taxes, Security Interests, options, warrants, purchase rights,
contracts, commitments, equities, claims, and demands. There are no outstanding
or authorized options, warrants, purchase rights, subscription rights,
conversion rights, exchange rights, or other contracts or commitments that could
require RCG to sell, transfer, or otherwise dispose of any capital stock of any
of its Subsidiaries or that could require any such Subsidiary to issue, sell, or
otherwise cause to become outstanding any of its own capital stock. There are no
outstanding stock appreciation, phantom stock, profit participation, or similar
rights with respect to any Subsidiary of RCG. There are no voting trusts,
proxies, or other agreements or understandings with respect to the voting of any
capital stock of any Subsidiary of RCG. None of RCG and its Subsidiaries
controls directly or indirectly, or has any direct or indirect equity
participation in, any corporation, partnership, trust, or other business
association which is not a Subsidiary of RCG.
 
     SECTION 8.7.  Financial Statements.  The RCG Disclosure Schedule includes
the following financial statements of RCG (collectively, the "RCG Financial
Statements"): (a) audited consolidated balance sheets and statements of income,
changes in stockholders' equity, and cash flows as of and for the fiscal year
ended December 31, 1996; (b) audited consolidated balance sheets and statements
of income, changes in stockholders' equity, and cash flows as of and for the
fiscal year ended December 31, 1997 (the "RCG Most Recent Fiscal Year End"); and
(c) unaudited consolidated balance sheets and statements of income and cash
flows (the "RCG Most Recent Financial Statements") as of and for the three
months and year to date period
                                      J-25
<PAGE>   565
 
ended March 31, 1998 (the "RCG Most Recent Fiscal Month End"). The RCG Financial
Statements (including the notes thereto) have been prepared in accordance with
GAAP applied on a consistent basis throughout the periods covered thereby and
present fairly the consolidated financial condition of RCG as of such dates and
the consolidated results of operations of RCG for such periods; provided,
however, that the RCG Most Recent Financial Statements are subject to normal
recurring adjustments (which will not be material individually or in the
aggregate) and lack footnotes and other presentation items. Without limiting the
generality of the foregoing, the RCG Most Recent Financial Statements accurately
reflect anticipated material costs to complete all contracts or services

     plan or "poison pill";
 
          (c) reclassify, combine, split, subdivide or redeem, purchase or

          (e) authorize or enter into any formal or informal agreement or

     Access from performing or cause World Access not to perform its covenants
     hereunder or result in any of the conditions to the Merger set forth herein
     not being satisfied.

<PAGE>   573
 
reasonable access at all reasonable times, and in a manner so as not to
interfere with the normal business operations, to all premises, properties,
personnel, books, records (including tax records), contracts, and documents of
or pertaining to each of the Parties and their Subsidiaries in accordance with
reasonable procedures required by the Parties that are designed to minimize the
impact on each Party's business. Each of the Parties will treat and hold as such
any Confidential Information it receives from any of the Parties and their
Subsidiaries in the course of the reviews contemplated by this Section, will not
use any of the Confidential Information except in connection with this
Agreement, and, if this Agreement is terminated for any reason whatsoever,
agrees to return all tangible embodiments (and all copies thereof), to whichever
of the Parties that originally disclosed such embodiments, which are in its
possession.
 
     SECTION 9.4.  Approval of Stockholders of New World Access.  Promptly
following the consummation of the Holding Company Reorganization, New World
Access will take all steps necessary under applicable law and its certificate of
incorporation and bylaws to call, give notice of, convene and hold a meeting of
its stockholders for the purpose of approving this Agreement and the Merger and
for such other purposes consistent with the complete performance of this
Agreement as may be necessary or desirable. Unless the Board of Directors of New
World Access determines in good faith, based upon advice of its outside counsel,
that such recommendation would violate its fiduciary duties to its stockholders,
the Board of Directors of New World Access will recommend to its stockholders
the approval of this Agreement, the Merger and the transactions contemplated
hereby and will use its best efforts to obtain the necessary approvals by its
stockholders of this Agreement, the Merger and the transactions contemplated
hereby.
 
     SECTION 9.5.  Preparation of Proxy Statement.  In connection with the
meeting of its stockholders to be held pursuant to Section 9.4 hereof, New World
Access shall promptly prepare a proxy statement for submission to its
stockholders (the "Proxy Statement"). RCG shall promptly furnish New World
Access with all information concerning its business and financial statements and
affairs which, in the reasonable judgment of New World Access or its counsel,
may be required or appropriate for inclusion in the Proxy Statement and shall
take such other action as they may reasonably request in connection with the
Proxy Statement. New World Access shall provide, and is responsible for, all
such information related to New World Access and Merger Sub, and RCG shall
provide, and is responsible for, all such information related to RCG. Once the
Proxy Statement has been authorized for mailing either by notice from the SEC or
by the lapse of time for review and comment by the SEC, New World Access shall
thereafter promptly mail to its stockholders the Proxy Statement in definitive
form (as amended or supplemented). Each of New World Access and RCG shall also
take such other reasonable actions as may be required to be taken under any
applicable state securities laws in connection with the issuance of shares of
New World Access Stock and the transactions contemplated by this Agreement.
 
     SECTION 9.6.  Affiliates.  Prior to the Closing Date, RCG shall deliver to
New World Access a letter identifying all Persons who are, at the time this
Agreement is submitted for approval to the stockholders of New World Access,
"affiliates" of RCG for purposes of Rule 145 under the Securities Act. RCG shall
use its best efforts to cause each such "affiliate" to deliver to New World
Access on or prior to the Closing Date a written agreement substantially in the
form attached as Exhibit "A."

done, all things necessary, proper or advisable under applicable laws and
regulations, or otherwise, including attempting to obtain all necessary
Consents, to consummate and make effective, as soon as practicable, the
transactions contemplated by this Agreement. Nothing in this Section 10.1 or
elsewhere in this Agreement shall be construed to require RCG, its shareholders
or agents to act in any manner inconsistent with Applicable Bankruptcy Law or
any of their respective duties thereunder.

     10.2.1. Following the execution and delivery of this Agreement, World
Access and RCG shall cause to be prepared and filed all required applications
and filings with the Regulatory Authorities which are necessary or contemplated
for the obtaining of the Consents of the Regulatory Authorities and the
consummation of the Merger, including any Consents required to be obtained under
the HSR Act or the Communications Act or from any state public service
commission ("PUC"). Such applications and filings shall be in such form as may
be prescribed by the respective government agencies and shall contain such
information as they may require. The Parties hereto will cooperate with each
other and use reasonable efforts to prepare and execute all necessary
documentation, to effect all necessary or contemplated filings and to obtain all
necessary or contemplated Consents of the Regulatory Authorities and third
parties which are necessary or contemplated to consummate the transactions
contemplated by this Agreement, including the stockholders of New World Access.
Each of the Parties shall have the right to review and approve in advance, which
approval shall not be unreasonably withheld, any filing made with, or written
material submitted to, any Regulatory Authority in connection with the
transactions contemplated by this Agreement.
 
     10.2.2. Each Party will furnish the other Parties with all information
concerning itself, its Subsidiaries, directors, officers and stockholders, as
applicable, and such other matters as may be necessary or advisable in
connection with any statement or application made by or on behalf of any such
Party to any governmental body in connection with the transactions, applications
or filings contemplated by this Agreement. Upon request, the Parties hereto will
promptly furnish each other with copies of written communications received by
them or their respective Subsidiaries from, or delivered by any of the foregoing
to, any governmental body in respect of the transactions contemplated hereby.
 
     SECTION 10.3.  Indemnification Regarding the Proxy Statement.  New World
Access, with respect to RCG, and RCG, with respect to New World Access, agree to
indemnify, defend and hold harmless the other, their respective Subsidiaries,
and each of their respective present and former officers, directors, employees
and agents, from and against all losses, expenses, claims, damages or
liabilities to which any of them may become subject under applicable laws
(including the Exchange Act), and will reimburse each of them for any legal,
accounting or other expenses reasonably incurred in connection with
investigating or defending any such actions, whether or not resulting in
liability, insofar as such losses, expenses, claims, damages or liabilities
arise out of or are based upon any untrue statement or alleged untrue statement
of material fact provided by the indemnifying Party and contained in the Proxy
Statement or arise out of or are based upon the omission or alleged omission by
the indemnifying Party to state therein a material fact necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading.
 
     SECTION 10.4.  Notice of Developments.  Each of the Parties will give
prompt written notice to other Parties of any material adverse development that
causes or is likely to cause a material breach of any of its representations and
warranties contained in this Agreement. Such disclosure by any Party pursuant to
this Section shall be deemed to amend or supplement any disclosure contained in
the Schedules attached hereto to prevent or cure any misrepresentation, breach
of warranty, or breach of covenant.
 
     SECTION 10.5.  Notices and Consents.  Each of the Parties will give any
notices (and will cause each of the Parties within their control to give any
notices) to third parties, and will use their reasonable efforts to obtain (and
will cause each of the Parties within their control to use their reasonable
efforts to obtain) any third-party consents that may be required to consummate
the transactions contemplated hereby.
 
SECTION 10.6.  Indemnity
 
     10.6.1. New World Access shall cause the Surviving Corporation to keep in
effect provisions of its articles of incorporation and bylaws providing for
exculpation of director and officer liability and its indemnification of each
Person who is now an officer or director of RCG to the fullest extent permitted
under the IBCA which provisions shall not be amended except as required by
applicable law or except to make changes permitted by law that would enlarge
such Persons' right of indemnification. The provisions of this
 
                                      J-35
<PAGE>   575
 
Section shall survive the consummation of the Merger and expressly are intended
to benefit each Person who is now an officer or director of RCG.
 
     SECTION 10.7.  Offers of Employment.  At the Closing, New World Access
shall execute and deliver to each of Steven A. Odom, John D. Phillips, Hensley
E. West, Mark A. Gergel and W. Tod Chmar an executive employment agreement in
substantially the form attached hereto as Exhibit "B".
 
SECTION 10.8.  Exclusive Dealing
 
     10.8.1. RCG shall not, nor shall it authorize or permit any officer,
director of employee of, or any attorney or other advisor or representative of,
RCG to, (i) solicit or initiate, or encourage the submission of, any Acquisition
Proposal or (ii) participate in any discussions or negotiations regarding, or
furnish to any Person any information with respect to, or take any other action
to facilitate any inquiries or the making of any proposal that constitutes, or
may reasonably be expected to lead to, any Acquisition Proposal.
 
     10.8.2. The Board of Directors of RCG shall not (i) approve or recommend,
or propose to approve or recommend, any Acquisition Proposal or (ii) enter into
any type of agreement or letter of intent with respect to any Acquisition
Proposal.
 
     10.8.3. If an Acquisition Proposal shall have been made prior to the
termination of this Agreement and RCG at any time thereafter consummates a
transaction contemplated by or resulting from such Acquisition Proposal, then
RCG shall pay, or cause to be paid, in same day funds, to World Access, upon
demand, all of the costs and expenses incurred by World Access in connection
with this Agreement, including fees and expenses of its financial advisors,
accountants and counsel (the "Expenses"), plus the sum of $5,000,000 (the
"Termination Fee"). The Parties acknowledge that damages in the event of a
breach of this Section 10.8 will be difficult to ascertain and that the Expenses
and the Termination Fee are intended to be full liquidated damages and such
damages represent the Parties' best estimate of such damages. RCG will recommend
that the Bankruptcy Court approve the payment of the Expenses and the
Termination Fee. The parties expressly acknowledge that the foregoing liquidated
damages are intended not as a penalty but as full liquidated damages in the
event of a breach of this Section 10.8, and World Access acknowledges the
Expenses and the Termination Fee are its sole and exclusive remedy for a breach
of this Section 10.8.
 
     10.8.4. In addition to the obligations of RCG set forth in Sections 10.8.1,
10.8.2 and 10.8.3 above, RCG shall immediately advise World Access orally and in
writing of any request for information or of any Acquisition Proposal, or any
inquiry with respect to or which could lead to any Acquisition Proposal, the
material terms and conditions of such request, Acquisition Proposal or inquiry,
and the identity of the Person making any Acquisition Proposal or inquiry. RCG
shall keep World Access fully informed of the status and details (including
amendments or proposed amendments) of any such request, Acquisition Proposal or
inquiry.
 
     10.8.5. Notwithstanding anything in Sections 10.8.1 and 10.8.2 to the
contrary, nothing contained in this Section 10.8 shall prohibit the Board of
Directors of RCG from furnishing information to, or entering into discussions or
negotiations or an agreement with, any Person or entity who has made an
unsolicited Acquisition Proposal if the Board of Directors of RCG determines in
its good faith judgment, based upon a written opinion of its independent
counsel, that such action is required for it to comply with its fiduciary duties
to RCG shareholders under applicable law or to otherwise comply with Applicable
Bankruptcy Law or any order of the Bankruptcy Court.
 
     SECTION 10.9.  Bankruptcy Court Approval.  Subject to Applicable Bankruptcy
Law, RCG shall use its best efforts to obtain Bankruptcy Court approval of the
Plan. Notwithstanding the foregoing, neither RCG nor any of its directors,
officers, attorneys or agents shall have any liability to World Access or New
World Access if the Plan is not confirmed other than as provided in Section
10.8.3 above.

     warranties of RCG in Article 8 hereof, provided that World Access or New

     its determination; or
 
          (c) by RCG at any time prior to the Effective Time, if (i) there has
     been a breach of a representation, warranty, covenant, or agreement of
     World Access or New World Access, and such breach has not been cured or is
     incapable of being cured within 15 days of notice of such breach; or (ii)
     RCG determines, in its sole good faith judgment, within thirty (30) days of
     the delivery of the World Access Disclosure Schedule, that the exceptions
     set forth therein are materially adversely different from the
     representations and warranties of World Access, New World Access and Merger
     Sub in Article 7 hereof, provided that RCG shall inform World Access and
     New World Access upon such termination as to the reasons for its
     determination; or

     November 1, 1998, unless extended by mutual written consent duly authorized
     by the boards of directors of New World Access and RCG (provided that the
     right to terminate this Agreement under this Section shall not be available
     to any Party whose failure to perform any material covenant or obligation
     or whose breach of a representation or warranty under this Agreement has
     been the cause of or resulted in the failure of the Closing to occur on or
     before such date); or
 
          (e) by New World Access or RCG if at the meeting of New World Access
     stockholders held for such purpose (including any adjournment or
     postponement thereof) the requisite vote of the New World Access
     stockholders to approve the Merger shall not have been obtained; or
 
          (f) by New World Access or RCG if the Plan is not confirmed by

     SECTION 14.2.  Effect of Termination and Breach.  In the event of
termination of this Agreement as provided in Section 14.1, this Agreement shall
forthwith become void and have no effect, without any liability or obligation on
the part of any Party, other than any liability or obligation arising under the
provisions of this Section 14.2 and Sections 10.8.3, 15.3 and 15.13; provided,
however, that in no event shall such termination relieve any Party of liability
for any breach by such Party of any of its covenants and agreements set forth
herein; and further provided, that no Party shall have any liability hereunder
for any breach of a representation or warranty of such Party except to the
extent that such breach shall have been the result of common law fraud,
intentional omission, deliberate concealment or gross negligence.
 
     SECTION 14.3.  Confidentiality Upon Termination.  In the event of any
termination of this Agreement for any reason, including any breach by any of the
Parties, each Party shall treat as confidential and shall not disclose, or use

their control to disclose, or to use, Confidential Information concerning the
other Parties obtained pursuant to or in connection with the Merger which is not

by a court of competent jurisdiction, including, without limitation, the
Bankruptcy Court.
 
     SECTION 14.4.  Specific Performance.  The Parties hereto agree that money
damages or other remedy at law would not be a sufficient or adequate remedy for
any breach or violation of, or a default under, this Agreement by them and that
in addition to all other remedies available to them, each of them shall be
entitled to the fullest extent permitted by law to an injunction restraining
such breach, violation or default or threatened breach, violation or default and
to any other equitable relief, including specific performance, without bond or
other security being required.

representations and warranties in this Agreement shall survive the Effective
Time, except for Section 8.9 hereof to the extent it applies to the period

Effective Time which shall survive for a one year period following the Effective
Time. Notwithstanding anything contained herein to the contrary, New World
Access shall be entitled, if it so elects, to set-off any Losses incurred as a
result of the breach of the representations and warranties set forth in Section

Consideration contemplated by this Agreement and certain additional agreements
are intended for the benefit of the stockholders of New World Access and the
creditors of RCG.
 
     SECTION 15.4.  Entire Agreement.  This Agreement (including the documents

subject matter hereof.

for an amount equal to the Share Consideration. Shareholder covenants that (a)
it has full power and the right to transfer the legal and beneficial title to
the Shares; (b) the Shares shall at Closing be free from any Liens or Security
Interests of any kind and from all other rights exercisable by third parties;
and (c) it will execute at its own cost and expense such documents as New World

rights attaching thereto.
 
     SECTION 2.2.  Consideration for Shares.  The consideration payable for the
Shares (the "Share Consideration") shall be equal to an aggregate of (a)
1,875,000 shares of New World Access Stock less (b) any shares of New World

Cherry U.K. Stock granted after the date hereof and converted by New World
Access in accordance with Section 2.3 below prior to the Closing plus (c) any
Escrowed Option Shares delivered to Shareholder pursuant to Section 2.5 below.
The number of shares of New World Access Stock to be issued to Shareholder at
Closing (the "Closing Shares") shall be equal to (a) one-third of the Share
Consideration (excluding the Escrowed Option Shares) plus (b) the number of
Option Shares (the "Extra Shares") underlying New World Access Options to the
extent that less than one-third of such shares may be acquired upon exercise
without regard to the conditions set forth in Article 4 hereof relating to the
release of Escrowed Shares. The remaining number of shares of New World Access
Stock (excluding the Escrowed Option Shares) comprising the Share Consideration
shall be issued and held in escrow pursuant to Section 2.4 below.
Notwithstanding anything to the contrary contained herein, no holder of the
Closing Shares may, until the 365th day following the Closing Date, without the
prior written consent of New World Access, offer, sell, contract to sell or
otherwise dispose of, directly or indirectly, any such shares or any security
convertible into or exchangeable or exercisable therefor, either publicly or
privately.
 
     SECTION  2.3.  Cherry U.K. Options.  From and after the date hereof, Cherry
U.K. may grant and award options or warrants to acquire Cherry U.K. Stock (each
a "Cherry U.K. Option") on the terms and conditions set forth in a Cherry U.K.
Option Agreement in a form to be mutually acceptable to Cherry U.K. and New
World Access, provided that the grantee of any such option or warrant (each a
"Cherry U.K. Optionholder") shall execute a counterpart of this Agreement and
thereupon become a Party hereto, and further provided, that the number of shares
of New World Access Stock issuable upon the exercise of such Cherry U.K. Options
(determined in accordance with this Section 2.3) does not exceed 937,500. Each
Cherry U.K. Option granted in accordance with the foregoing shall be assumed by
New World Access at the Effective Time and shall be converted into an option to
acquire New World Access Stock (each New World Access option or warrant granted
hereunder, a "New World Access Option") 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 provided
herein:
 
          (a) the number of shares of New World Access Stock to be subject to
     each New World Access Option (the "Option Shares") shall be equal to (i)
     the number of shares of Cherry U.K. Stock subject to such Cherry U.K Option
     so converted multiplied by (ii) the Equivalent Exchange Ratio;
 
          (b) the exercise price per share of New World Access Stock for each
     New World Access Stock Option issued pursuant hereto shall be equal to (i)
     the product obtained by multiplying the number of shares of Cherry U.K.
     Stock subject to the Cherry U.K. Option converted pursuant to this
     Agreement by the exercise price per share thereunder, divided by (ii) the
     number of shares of New World Access Stock issuable upon the exercise of
     such New World Access Option determined pursuant to clause (a) above;

<PAGE>   599
 
          (c) upon each exercise of the New World Access Options by a holder
     thereof, the aggregate number of shares of New World Access Stock
     deliverable upon such exercise shall be rounded up or down, if necessary,
     to the nearest whole share and the aggregate exercise price shall be
     rounded up or down, if necessary, to the nearest cent; and
 
          (d) notwithstanding anything herein to the contrary, a Cherry U.K.
     Optionholder may only exercise the New World Access Option to the extent of
     one-third of the Option Shares unless the Escrowed Shares are eligible for
     release pursuant to Article 4 hereof, in which event the New World Access
     Option may be exercised to the same extent as Escrowed Shares may be
     released and shall be subject to the same restrictions as provided in
     Section 4.4 hereof.
 
     Notwithstanding anything herein to the contrary, no Shares or Cherry U.K.
Options may be distributed or granted, without the prior written consent of New
World Access, if New World Access determines in its good faith judgment that
such actions would have a material adverse effect on the financial condition or
results of operations of New World Access and its Subsidiaries, taken as a
whole, for financial reporting purposes.
 
     SECTION 2.4.  Escrowed Shares.  Immediately following the Effective Time,
the Escrowed Shares shall be issued by New World Access and deposited with an
escrow agent mutually acceptable to New World Access and Shareholder (the
"Escrow Agent") pursuant to the terms of an Escrow Agreement substantially in
the form attached hereto as Exhibit "A" (the "Escrow Agreement"). The Escrow
Agent will release the Escrowed Shares to the Shareholder as set forth in
Article 4 hereof.
 
     SECTION 2.5.  Escrowed Option Shares.  Immediately following the Effective
Time, New World Access shall issue and deposit with an escrow agent mutually
acceptable to New World Access and Shareholder (the "Option Escrow Agent") an
aggregate number of shares of New World Access Stock equal to the aggregate
number of Option Shares (the "Escrowed Option Shares") pursuant to the terms of
an Escrow Agreement substantially in the form attached hereto as Exhibit "B"
(the "Option Escrow Agreement"). The Escrowed Option Shares shall be released
and delivered to New World Access for cancellation to the extent that the New
World Access Options (or any portion thereof) vest and become exercisable in
accordance with their terms. The Escrowed Option Shares shall be released and
delivered to Shareholder upon the forfeiture of any of the New World Access
Options (or any portion thereof) in accordance with the terms thereof as
follows: (a) an amount equal to (i) one-third of such shares less (ii) the
number of Extra Shares shall be released and delivered to Shareholder upon such
forfeiture, and (b) the balance of such shares (the "Contingent Escrowed Option
Shares") shall be released as set forth in Article 4 hereof.
 
     SECTION 2.6.  Adjustments.  In the event of any change in the New World
Access Stock after the date hereof by reason of any stock dividend, stock split,
subdivision, reclassification, recapitalization, combination, exchange of shares
or the like, then the New World Access Stock to be issued pursuant to this
Agreement (including pursuant to any New World Access Option) shall be adjusted
appropriately on the Closing Date.

comply with the provisions of Section 9.2, and New World Access shall issue to
Shareholder a certificate or certificates representing the Closing Shares and
shall issue to the Escrow Agent the Escrowed Shares, in each case rounded to the
nearest whole share. All certificates, documents and instruments representing
the Shares so surrendered shall be properly forwarded or otherwise in proper
form for transfer. At the Closing, New World Access shall deliver to each Cherry
U.K. Optionholder an option agreement representing the New World Access Option
into which such Cherry U.K. Optionholder's Cherry U.K. Option was converted.

</TABLE>
 
     Notwithstanding the foregoing, if the Closing Date is (a) on or after July
15, 1998 but prior to August 16, 1998, then the First Performance Period shall
commence on August 1, 1998 and shall terminate on (and including) December 31,
1998 and the Target EBITDA with respect thereto shall be reduced to $7,100,000,
(b) on or after August 16, 1998 but prior to September 30, 1998, then the First
Performance Period shall commence on September 1, 1998 and shall terminate on
(and including) December 31, 1998 and the Target EBITDA with respect thereto
shall be reduced to $6,700,000, or (c) on or after September 30, 1998, then the

combined EBITDA of Cherry U.K. and the surviving corporation of the U.S. Merger
is less than the Target EBITDA required for the release of Escrowed Shares in

to the contrary in Section 4.1, the Escrowed Shares shall be released if the
actual cumulative combined EBITDA for Cherry U.K. and the surviving corporation
of the U.S. Merger for such Performance Period and any subsequent Performance
Periods equals or exceeds the cumulative Target EBITDA for such Performance
Periods.
 
     SECTION 4.3.  Accelerated Release.  Notwithstanding anything to the
contrary, (a) if during any calendar quarter of the Second Performance Period,
the closing price per share of the New World Access 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 New World Access 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

restrictions set forth in Sections 2.2 and 4.4 shall not apply.
 
     SECTION 4.4.  Transfer Restrictions.  Notwithstanding anything to the
contrary contained herein, no holder of the Escrowed Shares upon their release
may, until the 180th day following the release date thereof, without the prior

                       WORLD ACCESS AND NEW WORLD ACCESS
 
     In order to induce Shareholder to enter into this Agreement, World Access
and New World Access, jointly and severally, represent and warrant to
Shareholder that, except as set forth in the World Access SEC Documents or the
Disclosure Schedule to be delivered by World Access to Shareholder within ten
(10) Business Days of the date hereof (the "World Access Disclosure Schedule"),
which World Access Disclosure Schedule shall identify exceptions by specific
Section references:
 
     SECTION 5.1.  Authority.  Each of World Access and New World Access has all
requisite corporate power and authority to execute, deliver and perform this
Agreement and the Ancillary Documents to be executed by them and to consummate
the transactions contemplated hereby and thereby. The execution and delivery of
this Agreement by World Access and New World Access and the consummation of the
transactions contemplated on their part hereby have been duly authorized by all
necessary corporate action, and, other than the approval of New World Access's
stockholders contemplated by Section 7.4 hereof, no other corporate proceedings
on the part of either World Access or New World Access are necessary to
authorize the consummation of the transactions contemplated on their part. This
Agreement has been duly executed and delivered by World Access and New World
Access and constitutes, and each of the Ancillary Documents to be signed at
Closing, when executed and delivered by World Access or New World Access (as the
case may be) will constitute, a valid and binding obligation of World Access and
New World Access (as the case may be), enforceable against them in accordance
with their respective terms, except to the extent that such enforceability may
be limited by applicable bankruptcy, insolvency, reorganization or other law
affecting the enforcement of creditors' rights generally or by general equity
principles.
 
     SECTION 5.2.  Organization, Qualification, and Corporate Power.  Each of
World Access and its Subsidiaries is a corporation duly organized, validly
existing, and in good standing under the laws of the jurisdiction of its
incorporation. Each of World Access and its Subsidiaries is duly authorized and
qualified to conduct business and is in good standing under the laws of each
jurisdiction where such qualification is required, except where the lack of such
qualification would not have a World Access Material Adverse Effect. Each of
World Access and its Subsidiaries has full corporate power and authority to
carry on the businesses in which it is engaged and to own, lease, use and
operate the properties owned, leased, used and operated by it. The copies of the
Certificate of Incorporation and the Bylaws of World Access and the equivalent
organizational documents of each of its Subsidiaries, which have previously been
made available to Shareholder, are true, complete and correct copies of such
documents as in effect as of the date of this Agreement.
 
     SECTION 5.3.  Capitalization.  The entire authorized common capital stock
of World Access consists of 40,000,000 shares of World Access Stock, of which
21,848,701 shares were issued and outstanding as of May 8, 1998. The entire
authorized common capital stock of New World Access consists of 40,000,000
shares of New World Access Stock, of which 1,000 were issued and outstanding as

                                      J-62
<PAGE>   602
 
shares of World Access Stock have been duly authorized and are validly issued,
fully paid, and nonassessable. Except as disclosed in the World Access SEC
Documents, there are no outstanding or authorized options, warrants, purchase
rights, subscription rights, conversion rights, exchange rights, or other
contracts or commitments that could require World Access or any of its
Subsidiaries to issue, sell, or otherwise cause to become outstanding any of its
capital stock. There are no outstanding or authorized stock appreciation,
phantom stock, profit participation, or similar rights with respect to World
Access and its Subsidiaries. World Access and its Subsidiaries have no
outstanding bonds, debentures, notes or similar obligations the holders of which
have the right to vote generally with holders of World Access Stock or New World
Access Stock.
 
     SECTION 5.4.  Non-contravention.  Neither the execution and the delivery of
this Agreement or the Ancillary Documents, nor the consummation of the
transactions contemplated hereby or thereby, will (a) violate any constitution,
statute, regulation, rule, injunction, judgment, order, decree, ruling, charge,
or other restriction of any government, governmental agency, or court to which
World Access or any of its Subsidiaries is subject or any provision of the
charter or bylaws of any of World Access or any of its Subsidiaries; or (b)
except with respect to those agreements for which Consent shall be obtained
prior to Closing, conflict with, result in a breach of, constitute a default
under, result in the acceleration of, create in any party the right to
accelerate, terminate, modify, or cancel, or require any notice under any
agreement, contract, lease, license, instrument, or other arrangement to which
World Access or any of its Subsidiaries is a party or by which it is bound or to
which any of its assets is subject (or result in the imposition of any Security
Interest upon any of its assets), except where the violation, conflict, breach,
default, acceleration, termination, modification, cancellation, failure to give
notice, or Security Interest would not have a World Access Material Adverse
Effect. Except for Consents required under or in relation to the (a) HSR Act,
(b) the Communications Act and any rates, regulations, practices and policies of
the FCC, (b) state securities or "blue sky" laws, (d) the Securities Act, (e)
the Exchange Act, (f) the DGCL, (g) laws, rules, regulations, practices and
orders of any PUC, foreign telecommunications regulatory agencies or similar
state or foreign regulatory bodies, (h) rules and regulations of NASDAQ, and (i)
such Consents and filings the failure of which to make or obtain would not have
a World Access Material Adverse Effect, neither World Access nor any of its
Subsidiaries is required to give any notice to, make any filing with, or obtain
any Consent of any Regulatory Authority in order for the Parties to consummate
the transactions contemplated by this Agreement and the Ancillary Documents. All

     SECTION 5.5.  Brokers' Fees.  None of World Access or any of its
Subsidiaries has any liability or obligation, contingent or otherwise, to pay
any fees or commissions or similar payments to any broker, finder, or agent with
respect to the transactions contemplated by this Agreement and the Ancillary
Documents, except to The Robinson-Humphrey Company, Inc., whose fees and
expenses will be paid by World Access in accordance with its agreement with such
firm based upon arrangements made by or on behalf of World Access and previously
disclosed to Cherry U.K.
 
     SECTION 5.6.  World Access SEC Documents.  Each of World Access and its
Subsidiaries has timely filed with the SEC all forms, reports, schedules,
statements, exhibits and other documents required to be filed by it since
December 31, 1995 with the SEC (such documents, as supplemented and amended
since the time of filing, collectively, the "World Access SEC Documents"). The
World Access SEC Documents, including any financial statements or schedules
included therein, at the time filed (and, in the case of registration statements
and proxy statements, on the dates of effectiveness and the dates of mailing,
respectively) (a) did not contain any untrue statement of a material fact or
omit to state a material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which
they were made, not misleading, and (b) complied in all material respects with
the applicable requirements of the Exchange Act and the Securities Act, as the
case may be. The consolidated financial statements (including the related notes)
of World Access included in the World Access SEC Documents (the "World Access
Financial Statements") comply as to form in all material respects with
applicable accounting requirements and the published rules and regulations of
the SEC with respect thereto, were prepared in accordance with GAAP (except, in
the case of unaudited statements, as permitted by Form 10-Q of the SEC) applied
on a

consistent basis during the periods involved (except as may be indicated in the
notes thereto), and fairly present (subject in the case of unaudited statements
to the absence of footnotes and to normal, recurring and year-end audit
adjustments which will not be material individually or in the aggregate) the
consolidated financial position of World Access as of the dates thereof and the
consolidated results of its operations and cash flows for the periods then
ended.

U.K. Material Adverse Effect. Each of Cherry U.K. and its Subsidiaries has full
corporate power and authority to carry on the businesses in which it is engaged
and to own, lease, use and operate the properties owned, leased, used and

subject (or result in the imposition of any Security Interest upon any of its
assets), except where the violation, conflict, breach, default, acceleration,
termination, modification, cancellation, failure to give notice, or Security
Interest would not have a Cherry U.K. Material Adverse Effect. Except for the
Required Consents and such Consents and filings the failure of which to make or
obtain would have a Cherry U.K. Material Adverse Effect, neither Shareholder,
Cherry U.K., nor any Subsidiary of Cherry U.K. is required to give any notice
to, make any filing with, or obtain any Consent of any Regulatory Authority in
order for the Parties to consummate the transactions contemplated by this

their respective terms, and there is not, to the Knowledge of Shareholder, under
any of such leases, any existing material default or event of default (or event
which, with notice or lapse of time, or both, would constitute a material
default) except where lack of such good standing, validity and effectiveness or
the existence of such default or event of default would not reasonably be
expected to have a Cherry U.K. Material Adverse Effect. All title deeds relating
to the assets of Cherry U.K. and its Subsidiaries and an executed copy of all

purchase rights, contracts, commitments, equities and demands. Other than the

connection with, any distribution thereof; (ii) understands and acknowledges
that such New World Access Stock or the New World Access Option (as the case may

intent as expressed herein; (iii) is able to bear the economic risk of an
investment in such New World Access Stock or the New World Access Option (as the
case may be) and has such knowledge and experience in financial and business
matters that he is capable of evaluating the risks and merits of such New World
Access Stock or the New World Access Option (as the case may be); (iv) has been
provided with all information or been given access to all information with
respect to New World Access which he believes might affect its decision whether

such New World Access Stock or New World Access Options issued pursuant to this
Agreement (as the case may be) will be "restricted securities" (as that term is
defined in Rule 144 under the Securities Act) and that the certificate
representing such New World Access Stock or the New World Access Option (as the
case may be) will bear a legend restricting transfer unless (A) the transfer is
exempt from the registration requirements under the Securities Act and any
applicable state securities law and an opinion of counsel reasonably
satisfactory to New World Access that such transfer is exempt therefrom is
delivered to New World Access or (B) the transfer is made pursuant to an

Access and New World Access and the shares of New World Access Stock or the New
World Access Option (as the case may be), upon the representations and
statements of World Access and New World Access set forth herein and upon the
World Access SEC Reports. Shareholder and each Cherry U.K. Optionholder

New World Access set forth herein and by World Access in the World Access SEC
Reports constitute the sole and exclusive representations, warranties, covenants
and statements of World Access and New World Access or any of its officers,

FOR IMMEDIATE RELEASE
 
     ATLANTA, GEORGIA -- May 12, 1998 -- WORLD ACCESS, INC.  (NASDAQ: WAXS),
announced today that it has signed definitive agreements 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"). The agreement to acquire RCG is subject to the approval of the
Bankruptcy Court.
 
     Pursuant to the terms of the agreements, the creditors of RCG and the
shareholders of Cherry U.K. will receive approximately 3.7 million shares of
World Access common stock in the aggregate, currently valued at approximately
$140 million. In addition, the RCG creditors and Cherry U.K. shareholders have
the right to receive additional consideration of up to 7.5 million shares of
World Access 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 World Access shareholders.
 
     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 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. Upon completion of the
Resurgens acquisition, WorldCom is expected to own approximately 15% of World
Access on a fully diluted basis.
 
     Steven A. Odom, Chairman and Chief Executive Officer of World Access, said,
"The acquisition of Resurgens is expected to close in the third quarter and
positively impact World Access earnings and cash flow beginning in the fourth
quarter of 1998. The acquisition uniquely positions the Company to offer its
customers a complete telecommunications network solution, including proprietary
equipment, planning and engineering services and access to international long
distance. The international network access offered by Resurgens is a critical
element of new and expanded networks currently being planned or implemented by
many World Access customers."
 
     "We believe the ability to offer both equipment and network access will
provide World Access with a comprehensive and cost-competitive product offering,
especially for international competitive local exchange providers ("CLECs") and
other providers of phone service in emerging growth markets. We have identified
numerous synergistic opportunities for World Access as a direct result of
Resurgens, including equipment sales to Resurgens customers, joint ventures with
international PTTs and CLECs, carrier service revenues from World Access
equipment customers and significant cost savings for the internal network of
Resurgens."

the combined company upon consummation of the transaction. He is one of the
pioneers of the U.S alternative long distance business, having built up Advanced

that WorldCom, a recognized leader in today's telecommunications industry, will
become the largest shareholder of the combined company."

Operations Center is now operational, and competitive, dedicated bandwidth and
transit agreements are in place. We currently expect Resurgens to generate
greater than $25 million in monthly revenues by July."
 
     "Steve Odom and his management team have done a tremendous job over the
past three years of building World Access into a highly respected, fast growing
telecommunications equipment company. Steve will continue to serve as the Chief
Executive Officer of the combined company and I look forward to working with him
as we continue to work towards achieving significant long-term value for World

ITEM 5.  OTHER EVENTS.
 
     On June 4, 1998, World Access, Inc. ("World Access") announced that it had
entered into a definitive Agreement and Plan of Merger and Reorganization (the
"Merger Agreement") with WAXS INC., a wholly-owned subsidiary of World Access
("New World Access"), Tail Acquisition Corporation, a wholly-owned subsidiary of
New World Access ("Merger Sub"), and Telco Systems, Inc. ("Telco") pursuant to
which, among other things, Merger Sub will merge with and into Telco and Telco
shall thereupon become a wholly-owned subsidiary of New World Access (the
"Merger").
 
     As a result of the Merger, each outstanding share of Telco common stock,
$.01 par value per share ("Telco Common Stock"), shall be converted into the
right to receive that number of shares of (i) World Access common stock, $.01
par value per share ("World Access Common Stock"), or (ii) if the previously
announced holding company reorganization shall have been consummated on or
before the time of the Merger, New World Access common stock, $.01 par value per
share ("New World Access Common Stock") (in either case, the "Merger Common
Stock") equal to the quotient of $17.00 divided by the average daily closing
price of World Access 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 Merger 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 Merger Common Stock.
 
     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 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 World Access (or New World Access, as the case may
be) and Telco, (iii) the approval by the stockholders of World Access or New
World Access (as the case may be) of an increase in the authorized shares of
common stock of such corporation, and (iv) the satisfaction or waiver of
customary conditions.
 
     In connection with the Merger Agreement, Kopp Investment Advisors, Inc. and
the directors and certain executive officers of Telco entered into a
Stockholders Proxy Agreement with New World Access pursuant to which, among
other things, they agreed to vote an aggregate of approximately 8.0% of the
outstanding shares of Telco Common Stock in favor of the Merger.
 
     The foregoing description of the Merger, the Merger Agreement and the
Stockholders Proxy Agreement is qualified in its entirety by reference to the
Merger Agreement and the Stockholders Proxy Agreement, each of which is filed as
an exhibit herewith and incorporated herein by reference. In addition, the Press
Release issued by World Access and Telco announcing the Merger is filed as an
exhibit herewith and incorporated herein by reference.

     "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 all rights in respect thereof shall forthwith cease to
     exist and shall be converted into and become exchangeable for that number

     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

     to exist and shall be converted into and become exchangeable for one newly
     and validly issued, fully paid and nonassessable share of common stock 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

certificates representing WAG Common Stock 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,

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 into which the shares of Company Common Stock theretofore represented by
the certificate or certificates so surrendered shall have been 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 any such
shares of WAG Common Stock 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 into which the shares
of Company Common Stock theretofore represented thereby shall have been
converted at the Effective Time. 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
 
                                      K-14

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 part
y hereto shall be liable to a holder of shares of Company Capital Stock for any
WAG Common Stock 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 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 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
 
                                      K-15
<PAGE>   648
 
(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;
 
          (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; 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, 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.
 
                                   ARTICLE IV
 
                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY
 
     The Company hereby represents and warrants to Parent and Merger Sub that:
 
     SECTION 4.01.  Organization and Qualification; Subsidiaries.  (a) The
Company and each directly and indirectly owned subsidiary of the Company (the
"COMPANY SUBSIDIARIES") has been duly organized and is validly existing and in
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

<PAGE>   649
 
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
capital stock or other equity interests owned by the Company or another Company
Subsidiary and (ii) an indication of whether each Company Subsidiary is a
"Significant Subsidiary" as defined in Regulation S-X under the Exchange Act.
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
year ended August 31, 1997 (the "COMPANY 1997 10-K") are true, complete and

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
have been designated as Company Junior Common Stock, and 5,000,000 shares of
preferred stock, 200,000 of which have been designated as Company Preferred

(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
Schedule sets forth a complete and correct list as of the date hereof of (w) the
number of options to purchase Company Common Stock outstanding and the number of
shares of Company Common Stock issuable thereunder, (x) the exercise price of

<PAGE>   650
 
validly issued, fully paid and nonassessable and each such share owned by the
Company or another Company Subsidiary is free and 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 "RIGHTS AGREEMENT"), relating

<PAGE>   651
 
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,

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,

31, 1997, neither the Company nor any Company Subsidiary has received from any

any of the senior executive officers of the Company or any of its Subsidiaries,

required to be reflected on a balance sheet or in notes thereto prepared in
accordance with U.S. GAAP, except for liabilities or obligations incurred in the
ordinary course of business consistent with past practice since August 31, 1997
that have not had and would not reasonably be expected to have, individually or

     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,

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

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

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

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.
Neither Parent nor Merger Sub is in violation of any of the provisions of its
certificate or bylaws.

all of which are validly issued, fully paid and nonassessable, (ii) no shares of
WAG Common Stock are held in the treasury of WAG, (iii) no shares of WAG Common

Parent Stock Plans, (v) 617,340 shares of WAG Common Stock are reserved for
issuance pursuant to outstanding warrants to purchase shares of WAG Common
Stock, and (vi) 3,105,485 shares of WAG Common Stock are reserved for issuance
upon conversion of WAG's 4.5% Convertible Subordinated Notes due 2002. As of the
date hereof, there are no shares of preferred stock of WAG issued and
outstanding. Upon consummation of the Holding Company Reorganization, the Parent

Stock issuable pursuant to the Parent Stock Plans, the Holding Company
Reorganization or the Resurgens Transaction or pursuant to agreements or
arrangements described in Section 5.03 of the Parent Disclosure Schedule, there
are no options, warrants or other rights, agreements, arrangements or

stock of WAG, Parent, Merger Sub or any other Parent Subsidiary or obligating
Parent, Merger Sub or any other Parent Subsidiary to issue or sell any shares of
capital stock of, or other equity interests in, WAG, Parent, Merger Sub or any
other Parent Subsidiary. All shares of WAG Common Stock subject to issuance (and

Parent Subsidiary to repurchase, redeem or otherwise acquire any shares of WAG
Common Stock, Parent Common Stock or any capital stock of any Parent Subsidiary.
Each outstanding share of capital stock of each Parent Subsidiary is duly
authorized, validly issued, fully paid and nonassessable and each such share
owned by WAG, Parent or another Parent Subsidiary is free and clear of all
security interests, liens, claims, pledges, options, rights of first refusal,
agreements, limitations on WAG's, Parent's or such other Parent 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 Parent Material Adverse
Effect. Except as set forth in Section 5.03 of the Parent Disclosure Schedule,
there are no outstanding contractual obligations of WAG, Parent, Merger Sub or
any other Parent Subsidiary to provide funds to, or make any material investment
(in the form of a loan, capital contribution or otherwise) in, any Parent
Subsidiary or any other person.
 
     SECTION 5.04.  Authority Relative to this Agreement.  WAG, Parent and
Merger Sub have all necessary corporate power and authority to execute and
deliver this Agreement, to perform their respective obligations hereunder and to
consummate the transactions contemplated hereby. The execution and delivery of
this Agreement by WAG, Parent and Merger Sub and the consummation by WAG, Parent
and Merger Sub 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 WAG, Parent or Merger Sub are necessary to authorize
this Agreement or to consummate such transactions (other than the approval of
the issuance of the WAG Common Stock or the Parent Common Stock, as the case may
be, pursuant to the Merger and the increase in the authorized WAG Common Stock
or Parent Common Stock (after the Holding Company Reorganization) to 100,000,000

authorization, execution and delivery by the Company, constitutes the legal,
valid and binding obligation of WAG, Parent and Merger Sub, enforceable against
WAG, Parent and Merger Sub in accordance with its terms.

materially delay the performance by WAG, Parent or Merger Sub of its obligations
pursuant to this Agreement or the consummation of the Merger.
 
     (b) The execution and delivery of this Agreement by WAG, Parent and Merger

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

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
WAG, Parent, Merger Sub or any other Parent Subsidiary is bound or affected or

     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 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 Company or the Company Subsidiaries, as applicable, immediately
following the Effective Time (each such employee, "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
 
                                      K-41
<PAGE>   674
 
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.
 
     (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.

     stockholders of WAG or Parent, as the case may be, in any such case in
     accordance with the Delaware General Corporation Law;
 
          (c) no court of competent jurisdiction shall have issued or entered
     any order, writ, injunction or decree, and no other Governmental Entity
     shall have issued any order (collectively, "Restraints"), which is then in
     effect and has the effect of making the Merger illegal or otherwise
     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
     terminated;
 
          (e) except with respect to the HSR Act (which is addressed in Section
     8.01(d)), all consents, approvals and authorizations legally required to be
     obtained to consummate the Merger shall have been obtained from all
     Governmental Entities, except where the failure to obtain any such consent,

     (contingent or otherwise), condition (financial or otherwise) or results of
     operations of WAG, Parent and the Parent Subsidiaries, taken as a whole;
     and
 
          (f) 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, issuable upon the exercise of Company Stock
     Options pursuant to Section 3.05 shall have been authorized for inclusion
     in Nasdaq, subject to official notice of issuance.

consummation of the Merger, are subject to the satisfaction or, if permitted by
applicable Law, waiver of the following further conditions:

     respects as of such certain date), in each case except as contemplated or
     permitted by this Agreement, and the Company shall have received a
     certificate of the Chairman or President and Chief Financial Officer of WAG
     and of Parent to such effect;
 
          (b) WAG and Parent shall each have performed or complied in all
     material respects with all material agreements and covenants required by
     this Agreement to be performed or complied with by it on or prior to the
     Effective Time and the Company shall have received a certificate of the
     Chairman or President and Chief Financial Officer of WAG and of Parent to
     that effect; and
 
          (c) Skadden, Arps, Slate, Meagher & Flom LLP, special counsel to the

     of the Code and that each of the Company, Merger Sub and Parent will be a
     party to the reorganization within the meaning of Section 368(b) of the

                       TERMINATION, AMENDMENT AND WAIVER
 
     SECTION 9.01.  Termination.  This Agreement may be terminated and the
Merger may be abandoned at any time prior to the Effective Time, notwithstanding
any requisite adoption and approval of this Agreement, as follows:
 
          (a) by mutual written consent duly authorized by the boards of
     directors of each of Parent and the Company;
 
          (b) by either Parent or the Company, if the Effective Time shall not
     have occurred on or before November 30, 1998; provided, however, that in
     the event that the Effective Time has not occurred by such time solely due
     to the failure to satisfy the condition specified in Section 8.01(d) or
     8.01(e), then such date may be extended, at the option of Parent or the
     Company, until December 31, 1998; provided further, that the right to
     terminate this Agreement under this Section 9.01(b) shall not be available
     to any party whose failure to fulfill any obligation under this Agreement
     shall have caused, or resulted in, the failure of the Effective Time to
     occur on or before such date;
 
          (c) by either Parent or the Company, if any Restraint shall have been
     entered and shall have become final and nonappealable, provided that the
     party seeking to terminate this Agreement pursuant to this Section 9.01(c)
     shall have used best efforts to prevent the entry of and to remove such
     Restraint;
 
          (d) by the Company, if prior to the Parent Stockholders' Meeting, the
     board of directors of WAG or Parent, as the case may be, withdraws,
     modifies or changes its recommendation of the issuance of the WAG Common
     Stock or the Parent Common Stock, as applicable, in the Merger or the
     Capital Increase in a manner adverse to the Company or its stockholders or
     shall have resolved to do so;
 
          (e) by Parent, if prior to the Company Stockholders' Meeting, (i) the
     board of directors of the Company withdraws, modifies or changes its
     recommendation of this Agreement or the Merger in a manner adverse to
     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
     stockholders of the Company a Competing Transaction or shall have resolved
     to do so, or (iii) a tender offer or exchange offer for 15 percent or more
     of the outstanding shares of capital stock of the Company shall have been
     commenced and the board of directors of the Company shall have failed to
     recommend against acceptance of such tender offer or exchange offer by its
     stockholders (including by taking no position with respect to the
     acceptance of such tender offer or exchange offer by its stockholders);
 
          (f) by Parent or the Company, (i) if this Agreement and the Merger
     shall fail to receive the requisite votes for approval at the Company
     Stockholders' Meeting or any adjournment or postponement thereof or (ii) if
     the issuance of shares of WAG Common Stock or Parent Common Stock, as the
     case may be, in the Merger or the Capital Increase shall fail to receive
     the requisite votes for approval at the Parent Stockholders' Meeting or any
     adjournment or postponement thereof;
 
          (g) by Parent, upon a breach of any representation, warranty, covenant
     or agreement on the part of the Company set forth in this Agreement, or if
     any representation or warranty of the Company shall have
 
                                      K-44
<PAGE>   677
 
     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 preceding proviso shall not
     in any event be deemed to extend any date set forth in paragraph (b) of
     this Section 9.01;
 
          (h) by the Company, upon breach of any representation, warranty,
     covenant or agreement on the part of Parent, WAG and Merger Sub set forth
     in this Agreement, or if any representation or warranty of Parent shall
     have become untrue, incomplete or incorrect, in either case such that the
     conditions set forth in Section 8.02 would not be satisfied (a "TERMINATING
     PARENT BREACH"); provided, however, that if such 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
 
                                      K-45
<PAGE>   678
 
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

Company'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 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.
 
     (e) Any payment required to be made pursuant to Section 9.05(b) shall be
made to Parent not later than the date of the entry into an agreement referred
to therein and two business days after delivery to the Company of notice of
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.

                               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

     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 mutually acceptable manner to the fullest

                          STOCKHOLDERS PROXY AGREEMENT
 
     STOCKHOLDERS PROXY AGREEMENT (this "Agreement"), dated as of June 4, 1998,
among WAXS INC., a Delaware corporation ("Parent"), and each other person and
entity listed on the signature pages hereof (each, a "Stockholder").
 
                              W I T N E S S E T H:
 
     WHEREAS, as of the date hereof each Stockholder owns (either beneficially
or of record) the number of shares of common stock, par value $0.01 per share
("Company Common Stock"), of Telco Systems, Inc., a Delaware corporation (the
"Company"), set forth opposite such Stockholder's name on Exhibit A hereto (all
such shares of Company Capital Stock owned by the Stockholders and any shares of
Company Capital Stock hereafter acquired by the Stockholders prior to the
termination of this Agreement being referred to herein as the "Shares");
 
     WHEREAS, (i) Kopp Investment Advisors, Inc. ("Kopp") has "investment power"
(as defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended
("Rule 13d-3")) with respect to 3,614,569 Shares owned by clients who have the
right to terminate their advisory agreements with Kopp ("Client Shares"), and
(ii) Kopp has "voting power" (as defined in Rule 13d-3) with respect to 415,600
Client Shares ("Client Voting Shares") (the Client Shares that are not Client
Voting Shares are referred to herein as "Client Advisory Shares");
 
     WHEREAS, Parent and the Company, among others, propose to enter into an
Agreement and Plan of Merger and Reorganization, dated as of the date hereof (as
the same may be amended from time to time, the "Merger Agreement"; capitalized
terms herein not otherwise defined herein shall have the meanings ascribed
thereto in the Merger Agreement), which provides, upon the terms and subject to
the conditions thereof, for the merger of a subsidiary of Parent with and into
the Company (the "Merger"); and
 
     WHEREAS, as a condition to the willingness of Parent to enter into the
Merger Agreement, Parent has requested that each Stockholder agree, and, in
order to induce Parent to enter into the Merger Agreement, each Stockholder has
agreed, to grant Parent proxies to vote such Stockholder's Shares;
 
     NOW, THEREFORE, in consideration of the premises and of the mutual
agreements and covenants set forth herein and in the Merger Agreement, the
parties hereto agree as follows:
 
                                   ARTICLE I
 
                         TRANSFER AND VOTING OF SHARES
 
     SECTION 1.01.  Transfer of Shares.  During the term of this Agreement, and
except as otherwise provided herein, each Stockholder (other than Kopp with
respect to the Client Shares) shall not (a) sell, pledge or otherwise dispose of
any of its Shares if such transaction would result in the Stockholder no longer
having the power to vote or cause to be voted the Shares, (b) deposit its Shares
into a voting trust or enter into a voting agreement or arrangement with respect
to such Shares or grant any proxy with respect thereto or (c) enter into any
contract, option or other arrangement or undertaking with respect to the direct
or indirect acquisition or sale, assignment, transfer or other disposition of
any of the Company Capital Stock if such transaction would result in the
Stockholder no longer having the power to vote or cause to be voted the Shares.
 
     SECTION 1.02.  Voting of Shares; Further Assurances.  (a) Each Stockholder,
by this Agreement, with respect to those Shares that it owns of record, does
hereby constitute and appoint Parent, or any nominee of Parent, with full power
of substitution, during and for the term of this Agreement, as its true and
lawful attorney and proxy, for and in its name, place and stead, to vote each of
such Shares as its proxy, at every annual, special or adjourned meeting of the
stockholders of the Company (including the right to sign its name (as
stockholder) to any consent, certificate or other document relating to the
Company that the law of the State of Delaware may permit or require) (i) in
favor of the adoption of the Merger Agreement and approval
 
                                      K-51
<PAGE>   684
 
of the Merger and the other transactions contemplated by the Merger Agreement,
(ii) against any proposal for any recapitalization, merger, sale of assets or
other business combination between the Company and any person or entity (other
than the Merger) or any other action or agreement that would result in a breach
of any covenant, representation or warranty or any other obligation or agreement
of the Company under the Merger Agreement or which could result in any of the
conditions to the Company's obligations under the Merger Agreement not being
fulfilled, and (iii) in favor of any other matter relating to consummation of
the transactions contemplated by the Merger Agreement. Each Stockholder further
agrees to cause the Shares owned by it beneficially to be voted in accordance
with the foregoing. Each Stockholder acknowledges receipt and review of a copy
of the Merger Agreement. Notwithstanding anything in this Section 1.02(a) to the
contrary, the Client Advisory Shares shall not be subject to this Section
1.02(a) and the Client Voting Shares shall cease to be subject to this Section
1.02(a) if and when the owner of such Client Voting Shares terminates its
advisory agreement with Kopp.
 
     (b) Each Stockholder shall perform such further acts and execute such
further documents and instruments as may reasonably be required to vest in
Parent the power to carry out the provisions of this Agreement.
 
     (c) Nothing contained in this Agreement shall be deemed to restrict a
Stockholder who is also a director of the Company from taking actions in his
capacity as a director as may be permitted under the Merger Agreement.
 
     SECTION 1.03.  Term of Agreement.  This Agreement shall be effective as of
the date hereof and shall expire on the earlier of (a) the Effective Time and
(b) the date of the termination of the Merger Agreement pursuant to its terms.
 
                                   ARTICLE II
 
                       REPRESENTATIONS AND WARRANTIES OF
                                  STOCKHOLDERS
 
     Each Stockholder, severally and not jointly, hereby represents and warrants
to Parent as follows:
 
     SECTION 2.01.  Due Organization, Etc.  Such Stockholder (if it is a
corporation, partnership or other legal entity) is duly organized and validly
existing under the laws of the jurisdiction of its organization. Such
Stockholder has full power and authority (corporate or otherwise) to execute and
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
effect of general principles of equity (regardless of whether such
enforceability is considered in a proceeding in equity or at law).
 
     SECTION 2.02.  No Conflicts; Required Filings and Consents.  (a) The
execution and delivery of this Agreement by such Stockholder do not, and the
performance of this Agreement by such Stockholder will not, (i) conflict with or
violate the Certificate of Incorporation or ByLaws or similar organizational
documents of such Stockholder (in the case of a Stockholder that is a
corporation, partnership or other legal entity), (ii) conflict with or violate
any law, rule, regulation, order, judgment or decree applicable to such
Stockholder or by which it 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
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>   685
 
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
extent described in its Schedule 13D dated May 13, 1998 and in Exhibit A hereto,
such Stockholder is the record or beneficial owner of its Shares free and clear
of any proxy or voting restriction other than pursuant to this Agreement.

and delivery of this Agreement and the consummation of the transactions
contemplated hereby by Parent have been duly authorized by all necessary

delivery by the Stockholders, constitutes a legal, valid and binding obligation
of Parent, enforceable against Parent in accordance with its terms.

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

[LOGO] WORLD ACCESS, INC.                                           NEWS RELEASE
 
          SUMMARY: WORLD ACCESS, INC. AND TELCO SYSTEMS, INC. TO MERGE
 
                             FOR IMMEDIATE RELEASE
 
     ATLANTA, GEORGIA -- June 4, 1998 -- WORLD ACCESS, INC. (Nasdaq: WAXS) and
Telco Systems, Inc. (Nasdaq: TELC) announced today that they have entered into a
definitive agreement to merge the two companies. The closing of the merger is
subject to the satisfaction of customary conditions, including the receipt of
stockholder and regulatory approvals. The transaction is expected to be
accounted for as a purchase and to qualify as a tax-free reorganization. The
combined company will retain the World Access name.
 
     Telco Systems, based in Norwood, Massachusetts, has supplied products and
related services to the telecommunications industry since 1972. The company is
well known for its asynchronous fiber optic systems and intelligent channel
banks, with an installed base of over $1 billion. Today, the company
concentrates on the integrated access, high capacity multiplexer and Frame
Relay/ATM access markets. Telco Systems has established supply contracts with
leading telecommunications service providers, including NYNEX/Bell Atlantic,
GTE, British Telecom and Concert Communications, and has recently introduced
several new products, including its Access45(TM) and EdgeLink100(TM). During its
latest fiscal year, Telco Systems generated approximately $120 million in
revenues.
 
     The merger agreement provides that each of the approximately 11 million
shares of Telco Systems common stock will be converted into shares of World
Access common stock having a value of $17.00 per share, 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 Telco Systems 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 Telco Systems common stock will be converted into 0.5862 shares of
World Access common stock.
 
     The merger agreement has been unanimously approved by the Boards of
Directors of both companies. The Robinson-Humphrey Company, LLC is acting as
financial advisor to World Access on this transaction and Broadview Associates
LLC is representing Telco Systems.
 
     The companies will be sponsoring a teleconference to review the planned
merger on Friday, June 5, 1998, at 8:30 a.m., EDT. To participate in this
teleconference, interested parties should call 212-346-6404. A taped replay will
be available on Friday from 12:00 p.m. to 8:00 p.m. and on Monday from 8:00 a.m.
to 5:00 p.m. To listen to the taped replay, call 1-800-633-8284 and enter
reservation #4374730 (international callers must dial 303-248-1201 and then the
reservation number).
 
     Steven A. Odom, Chairman and Chief Executive Officer of World Access, said,
"The combination of World Access and Telco Systems will strengthen our
competitive positioning in the global telecommunications market. The proprietary
technology, advanced product offerings and strong customer relationships
contributed by Telco Systems will significantly enhance our ability to support
and service our collective customers as they build new and/or upgrade existing
telecommunications networks. The merger is expected to be consummated in the
third quarter and positively impact World Access earnings per share for calendar
year 1999."
 
     Hensley E. West, President and Chief Operating Officer of World Access,
added, "We are pleased that Telco's team of experienced industry professionals
will continue to manage Telco Systems as a key division of World Access. Telco
Systems will become the cornerstone of our transport and access product areas,
encompassing several other existing World Access divisions. The integration of
these divisions will provide a technology and product focus geared towards
meeting the increasing demands for value-added network access
 
                                      K-59

systems. As a result of the merger, we will provide our customers greater
network solutions capabilities, in addition to the network access services that
will be available as a result of the pending Resurgens acquisition."
 
     Dr. William B. Smith, President and Chief Executive Officer of Telco
Systems, said, "The strong management team we've assembled at Telco Systems over
the past few years is excited to join forces with World Access. We have
concentrated on developing competitive high-speed multiplexer and integrated
access systems employed at the edge of the network and have recently released
several new products that are receiving excellent market acceptance. We look
forward to combining talents with World Access to offer our broad customer base
a more complete network solution."
 
     While much of Telco Systems' revenue is generated through the sale of
equipment directly to approximately two dozen large service providers around the
world, the company brings to World Access a solid set of distribution partners,
including Walker and Associates, Sprint North Supply, GTE Supply, Alltel Supply
and TelSource. In addition, Telco Systems has relationships with over 40
distributors in international markets. The combined portfolio of World Access
and Telco Systems will give all of the combined company's sales channels a more
complete line of product solutions.
 
     Each company brings to this alliance distinct competencies that will offer
immediate operational efficiencies, especially in the areas of manufacturing and
customer service. For example, World Access' manufacturing infrastructure
includes "rack 'n stack" configuration capabilities that will be available for
Telco Systems' products and customers. With this capability, many different
product configurations can be pre-assembled and tested for immediate shipment,
offering a competitive advantage in the sales process. Both companies are ISO
certified, and have well established and documented operating procedures to
assure high quality products and services are provided to their customers.
 
     World Access, Inc. develops, manufactures and markets wireline and wireless
switching, transport and access products for the global 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. 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. 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.

ACCESS AND TELCO SYSTEMS, AND THE SUCCESS OF THE PROPOSED MERGER MAY DIFFER FROM

                   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.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     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

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
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.

     Goodwill is being amortized on a straight-line basis over a 15 to 20 year
period. In accordance with Statement of Financial Accounting Standards No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
Be Disposed Of", the Company regularly reviews the projected future cash flows
from operations of each of the acquired businesses to assess the recoverability
of goodwill. In the 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 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

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
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.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
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.
 
NOTE 10.  COMPREHENSIVE INCOME
 
     The Company adopted Statement of Financial Accounting Standards No. 130
("SFAS 130"), "Reporting Comprehensive Income", effective January 1, 1998. For
the six months ended June 30, 1998 and 1997, respectively, comprehensive and net
income were the same for the Company.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS
 
DISCLOSURE REGARDING FORWARD-LOOKING STATEMENTS
 
     Under the Private Securities Litigation Reform Act of 1995, companies are
provided a "safe harbor" for making forward-looking statements about the
potential risks and rewards of their strategies. The Company believes that it is
in the best interest of its stockholders to use these provisions in discussing
future events in this Form 10-Q and other communications. These forward-looking
statements include the Company's plans for growth, the potential for
development, acceptance of the Company's products and other factors that could
affect the Company's future operations or financial position.
 
     The Company's ability to achieve its goals depends on many known and
unknown risks and uncertainties, as well as changes in general economic and
business conditions. These factors could cause the anticipated performance and
results of the Company to differ materially from those described or implied in
such forward-looking statements.
 
     Factors that could cause or contribute to such differences include the
risks and uncertainties described in the Company's SEC reports, including the
Company's Annual Report on Form 10-K, as amended, for the year ended December
31, 1997 and the Company's Registration Statement on Form S-3 (No. 333-43497).
 
OVERVIEW
 
     The Company develops, manufactures and markets wireline and wireless
switching, transport and access products for the global telecommunications
markets. The products offered by the Company include those manufactured by the
Company as well as those manufactured by other telecommunications equipment
manufacturers. 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.
 
     During 1995 and 1996, the Company completed strategic and financial
restructuring programs to strengthen its management team, reposition the Company
as a provider of telecommunications products, improve its financial condition,
reduce its operating costs and position the Company for future growth. These
programs were undertaken following the significant losses incurred by the
Company in the early 1990s, primarily due to a discontinued smart pay telephone
business, and to take advantage of the significant growth opportunities within
the Company's existing customer base and related markets. In November 1994, the
Company began to rebuild its management team and change its strategic focus. The
Company 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 the Company, have brought significant
experience in manufacturing and marketing telecommunications equipment to the
Company.
 
     The Company 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, the Company acquired AIT, Inc. ("AIT"), a full service provider of
Northern Telecom switching systems, add-on frames and related circuit boards;
effective October 1995, the Company acquired Westec Communications, Inc.
("Westec"), a provider of wireless products and services primarily to the cable
television industry; effective January 1996, the Company acquired Sunrise
Sierra, Inc. ("Sunrise"), a developer and manufacturer of intelligent transport
and access products; effective January 1997, the Company acquired Cellular
Infrastructure Supply, Inc. ("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, the Company
acquired Galaxy Personal Communication Services ("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 the Company's
traditional telephone service provider and private network operator markets.
 
     In the first quarter of 1998, the Company 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
 
                                      L-12
<PAGE>   708
 
advanced telecommunications switching platforms with integrated applications
software. In May 1998, the Company 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, the Company
signed a definitive agreement to acquire Telco, 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 the Company to offer its customers a complete telecommunications
network solution, including proprietary equipment, planning and engineering
services and access to international long distance.
 
     The Company realized significant improvements in its sales and operating
results since 1994 as a result of the acquisitions and internal growth
initiatives. The Company's 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 the Company 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, the Company's
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. The Company 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 the Company has aggressively pursued acquisitions in recent years,
approximately 50% of the Company's total sales growth since 1994 has come from
internal growth initiatives. The Company has had considerable success in growing
businesses subsequent to their acquisition, due in part to the Company's ability
to provide working capital, an extensive base of telecommunications customers
and a broad range of support services.
 
     Since January 1, 1995, the Company 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. The Company has used this capital for acquisitions and to
support the working capital requirements associated with the Company's growth.
The Company's 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.
 
FLUCTUATIONS IN QUARTERLY OPERATING RESULTS
 
     The Company's operating results have fluctuated significantly in the past.
As the Company increases its number of telecommunications product offerings, its
future operating results may vary significantly depending on factors such as the
timing and shipment of significant orders, new product offerings by the Company
and its competitors, market acceptance of new and enhanced versions of the
Company's products, changes in pricing policies by the Company and its
competitors, the availability of new technologies, the mix of distribution
channels through which the Company's product are sold, the inability to obtain
sufficient supplies of sole or limited source components for the Company's
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.
 
     The Company's 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 the Company 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 were acquired
effective February 1, 1998 and March 1, 1998, respectively, and increases in
sales of the Company's international switching product, the Compact Digital
Exchange switch ("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 the Company's manufacturing capacity for new World Access
products rather than service outside contract manufacturing customers.

<PAGE>   710
 
     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%. The Company's 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
the Company's 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 the Company) 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 the Company,
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 the Company's international switching product, the Compact Digital
Exchange switch ("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 the Company's
manufacturing capacity for new World Access products rather than service outside
contract manufacturing customers and in the Company's 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%. The Company's 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 the Company's 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 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.
                                      L-16
<PAGE>   712
 
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 the Company, 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 (see Note 2 to the "Financial
Statements"). 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. The Company expects to record an
additional in-process research and development charge of approximately $22.0
million in the third 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
                                      L-17
<PAGE>   713

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
Compact:                                          95.0% of units in development
QAM:                                             100.0% of units in development
</TABLE>
 
     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, the Company's senior management decided that the following
actions were necessary to streamline operations and position the Company 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 Westee'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 Westee 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 the Company, e.g., relocation of existing employees,
recruiting and training of new employees and facility start-up costs. The
special charge consisted of:

  Obsolete and redundant inventories........................  $3,360,000
  Severance and termination benefits........................     550,000

                                                              $6,600,000
                                                              ==========
</TABLE>
 
     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 the
Company's 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
 
                                      L-18
<PAGE>   714
 
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 the Company 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 Report, the Company 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 the Company 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 the Company's 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, the Company 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 the Company
(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. The Company's transition into equipment sales has caused an
increase in days sales outstanding. The Company's equipment sales tend to
include longer payment terms than the historical repair and refurbishment
businesses. In addition, the Company's sales to international customers have
increased during the last twelve months. International sales generally have
payment terms of 90 to 120 days. The Company also has recently begun to enter
into long-term notes receivable with selected customers. To maximize cash flow,
the Company 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 the Company's 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).
 
     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, 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 common
stock (the "NACT Stock Acquisition"). On February 27, 1998 the
                                      L-19
<PAGE>   715
 
NACT Stock 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 $26.9 million. This transaction
increased the Company's ownership of NACT to 67.3%.
 
     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 then 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. This merger is expected to be consummated in September
1998.
 
     On December 24, 1997, the Company 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 the Company's 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 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. 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 the Company's December 31, 1997 balance sheet.
During the first quarter of 1998, the note receivable was included in the
Company's purchase price of ATI.
 
     During the first six months of 1998 and 1997, the Company invested $5.9
million and $1.1 million, respectively, in capital expenditures. The Company 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 the Company's management
information systems and facilitate the integration of acquisitions, and facility
improvements required in connection with the Company's growth.
 
     The Company 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, the Company 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, 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 initial purchasers' discount fees of $3.0
million.
 
     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 $14.6 million, after the application of the initial purchasers'
discount fees.
 
                                      L-20
<PAGE>   716
 
     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 the Company's June 30, 1998 balance sheet.
 
     As of June 30, 1998, the Company had borrowings of $4.3 million outstanding
under its $10.0 million revolving line of credit. Borrowings under the Company's
line of credit 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. As of the date of this Report, there were no amounts outstanding
under the Company's line of credit.
 
     During the first six months of 1998 and 1997, the Company 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 the Company's directors and
employees.
 
     Income Taxes.  As a result of the exercises of non-qualified stock options
and warrants by the Company's directors and employees, the Company 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 the
Company's provision for income tax expense, it represents a significant cash
benefit to the Company. 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.  The Company's 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. As of the date of this Report,
the Company has approximately $60.0 million of cash and a $10.0 million
revolving line of credit available. The Company believes that existing cash
balances, available borrowings under the Company's line of credit and cash
projected to be generated from operations will provide the Company 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 the Company's computer
systems that have date sensitive software may recognize a date using "00" as the
year 1900 rather than the year 2000 (the so-called "Year 2000 Issue"). This
could result in a system failure or miscalculations causing disruptions,
including, among other things, a temporary inability to process transactions,
send invoices or engage in normal business activities.
 
     The Company 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 the
Company's computer systems have been put into service within the last several
years, the Company does not expect any such modifications to have a material
adverse effect on the Company's consolidated results of operations, liquidity
and capital resources.
 
     In addition, the Company is in the process of developing a plan whereby it
will review the year 2000 readiness of its customers and suppliers. In doing so,
the Company will undertake appropriate internal reviews and will contact certain
of its significant customers to assess, to the extent possible, Year 2000 Issues
related to the Company's products. In that regard, the Company has identified
that certain of its products, including the NTS 1000 billing System available
from one of the Company's subsidiary, are not year 2000 compliant. The Company
is in the process of releasing new versions of such products and making
necessary modifications to existing products to address the Year 2000 Issue.
These new and revised products are expected to be available commencing in the
first quarter of 1999. The Company expects that many of its customers will
upgrade to the new products. However, there can be no assurance that the
Company's customers will upgrade to the new year 2000 compliant products or that
the modifications planned to the certain of the Company's existing products
 
                                      L-21
<PAGE>   717
 
will be successful or completed in a timely manner. The Company will continue to
evaluate its other products to determine their year 2000 compliance.
 
     The Company intends to take all reasonable efforts to make information on
the year 2000 readiness of its products available to its customers, although
this information may not reach all customers, particularly indirect purchasers
of the Company's products. Although the Company 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.
 
     The Company 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 the Company will function properly or be available without
interruption in the year 2000. Nevertheless, it will be impossible for the
Company 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, the Company
also intends to develop a business continuity plan to minimize the impact of
such external events.
 
     While the Company's efforts to address year 2000 issues will involve
additional costs and the time and effort of a number of Company employees, the
Company believes, based on currently available information, that it will be able
to manage its total year 2000 transition without any material adverse effect on
the Company's consolidated results of operations, liquidity and capital
resources.

ITEM 5.  OTHER EVENTS
 
     As previously reported, on May 12, 1998, World Access, Inc. (the "Company")
announced that it had entered into (i) a definitive Agreement and Plan of Merger
and Reorganization, as subsequently amended (as so amended, the "Merger
Agreement"), with Cherry Communications Incorporated (d/b/a Resurgens
Communications Group) ("RCG") pursuant to which the Company will acquire RCG in
a merger transaction (the "Merger"), and (ii) a Share Exchange Agreement and
Plan of Reorganization (the "Exchange Agreement") with the sole shareholder (the
"Shareholder") of Cherry Communications U.K. Limited ("Cherry U.K.") pursuant to
which the Company will acquire Cherry U.K. in a share exchange transaction (the
"Exchange").
 
     In connection with the Merger, the former creditors of RCG will receive an
aggregate of 9,375,000 shares of common stock of WAXS INC. ("New World Access").
New World Access is a wholly-owned subsidiary of the Company that will become
the parent of the Company upon the completion of the previously reported
acquisition of the shares of NACT Telecommunications, Inc. ("NACT") not already
owned by the Company and the holding company reorganization to be effective in
connection therewith (the "Holding Company Reorganization"). Of the shares of
New World Access common stock to be issued to the RCG creditors, two-thirds will
be held in escrow and will be released to the RCG creditors over the two and
one-half years following the consummation of the Merger subject to the
attainment of certain earnings levels for the combined business of RCG and
Cherry U.K.
 
     In connection with the Exchange, the Shareholder will receive an aggregate
of 1,875,000 shares of New World Access common stock, of which one-third will be
issued to the Shareholder at closing and the remaining two-thirds will be issued
and held in escrow and will be released to the Shareholder over the two and
one-half year period following the consummation of the Exchange subject to the
attainment of certain earnings levels for the combined business of RCG and
Cherry U.K. The Exchange Agreement pursuant to which provides, however, that the
number of shares of New World Access common stock to be received by the
Shareholder will be reduced to the extent that New 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 New World Access, into options to
acquire New World Access common stock. It is currently expected that no such
options will be granted.
 
     Each of the Merger and the Exchange is subject to the satisfaction of
certain conditions customary in similar transactions, including the approval of
the Company's stockholders and the consummation of the Holding Company
Reorganization. The consummation of the Merger is also subject to the Bankruptcy
Court's approval and confirmation of RCG's Plan of Reorganization pursuant to an
order dated September 3, 1998. Finally, the consummation of the Merger is a
condition to the consummation of the Exchange, and the Exchange is a condition
to the consummation of the Merger.
 
     The foregoing description of the Merger and the Exchange is qualified in
its entirety by reference to the Merger Agreement and the Exchange Agreement
which have been filed as exhibits to the Company's Form 8-K filed with the
Commission on May 18, 1998; however, the First and Second Amendments to the
Merger Agreements are filed as exhibits herewith.
 
ITEM 7.  FINANCIAL STATEMENTS, PRO FORMA FINANCIAL INFORMATION AND EXHIBITS
 
     (a) Financial Statement of Business Acquired. Included in this report are
the following financial statements:
 
          (i) The combined unaudited financial statements of Cherry
     Communications Incorporated (d/b/a Resurgens Communications Group) ("RCG")
     and Cherry Communications U.K. Limited ("Cherry U.K.") for the six months
     ended June 30, 1998 and 1997;
 
          (ii) The combined financial statements of RCG and Cherry U.K. for the
     year ended December 31, 1997, which have been audited by the independent
     accounting firm of Ernst & Young LLP, whose opinion thereon is included
     herein; and
 
                                       M-1
<PAGE>   722
 
          (iii) The combined financial statements of RCG and Cherry U.K. for the
     year ended December 31, 1996, which have been audited by the independent
     accounting firm of Grant Thornton LLP, whose opinion thereon is included
     herein.
 
     (b) Pro Forma Financial Information. The Unaudited Pro Forma Combined
Financial Statements of New World Access give effect to the consummation of 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 acquisition of Advanced TechCom, Inc.; (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 acquisition of RCG and
Cherry U.K. (the "Resurgens Transaction"); and (5) the acquisition of Telco
Systems, Inc. ("Telco 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, Resurgens Transaction and the Telco Merger as if it had
been completed on June 30, 1998.
 
     As the fiscal year end of Telco Systems, Inc. ("Telco"), August 31, differs
from the Company's fiscal year-end by more than 93 days, Telco's 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's results of operations for the six
months from December 1, 1997 through May 31, 1998 were used in preparing the
Unaudited Pro Forma Combined Statement of Operations for the six months ended
June 30, 1998. Telco's May 31, 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 Company's management 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 Company's
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 acquisition
transactions, the Company expects New World Access to record charges
representing the estimated portion of the purchase price allocated to in-
process research and development of $21.9 million and $73.9 million for the NACT
Transaction and Telco Merger, respectively. In addition, in the three month
period ended March 31, 1998, the Company 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. 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 the Company, ATI, NACT, Resurgens and
Telco, and the related notes thereto.

                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.

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
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.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED)
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.
 
     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.

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.

2. PETITION FOR RELIEF UNDER CHAPTER 11 BANKRUPTCY -- (CONTINUED)
     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.
 
     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.

     Under the two WorldCom installment notes, which are secured by
substantially all of the Companies' assets and stock of the Corporations, any
defaults allow WorldCom to charge interest at 18% annually on all outstanding
balances, and to request the entire indebtedness to become due. The Companies
have defaulted on the $50,000 note payable due December 30, 1997, and subsequent
to year end, defaulted on the March 31, 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.

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.
 
     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

     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.
 
     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 Companies incurred substantial losses in 1995 and 1996
and have disputed significant net accounts payable balances due their 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.

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED)
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.
 
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
their Companies' ability to meet their obligations as they come due and to
obtain financing or an equity infusion. The Companies' actions to address their
current liquidity constraints and their financial performance include
negotiations with potential lenders or equity participants. However, there can
be no assurances that the Companies' actions will improve their financial
performance or liquidity position or that they can avoid default on the December
31, 1997 payment of the $50,000,000 note obligation.

     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,

NOTE 5. 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 and accrued expenses approximate carrying
value, principally because of the short maturity of these items.
 
     The carrying amounts of the long-term debt payable approximates fair value
due to the interest rates on these agreements approximating Cherry's incremental
borrowing rates.
 
     The fair values of capitalized lease obligations approximate carrying value
based on their effective interest rates compared to current market rates.

     The Companies lease telecommunications and other equipment through various

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, 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.

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 New 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, 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
July 9, 1998, World Access, GST and Aerotel entered into a Memorandum of
Understanding to settle the Aerotel litigation. Including legal fees, World
Access now estimates its Aerotel settlement costs will be approximately $3.3
million. The settlement costs expected to be incurred by World Access 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 New 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
 
                                      M-57

   NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
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.
 
     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 included significant
redevelopment of some existing products and the creation of new products. 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.
 
     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

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.  Telco develops and manufactures products focused on providing
integrated access for network services. Telco's products can be separated into
three categories: (1) broadband transmission products, (2) network access
products, and (3) bandwidth optimization products. Telco's 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 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's 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's in process research
and development are expected to include interface support not in Telco's current
product line, including E1, DS3 and OC3.
 
     None of the in-process projects at Telco considered in the write-off are
expected to achieve technological feasibility before the consummation of World
Access' acquisition of Telco. 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's 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's old products by these new products as well as the
expected growth in the overall market in which Telco's 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 (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 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.

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. New
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.

     (i) Represents an estimate of $1.0 million to be paid to the creditors of
Resurgens under a cash settlement plan proposed by New World Access and
approximately $2.0 million to be paid to governmental creditors.
 
     (ii) The value assigned to the 3,750,000 restricted New 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 New 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. New 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 New
World Access common stock [the closing price on the announcement date was $37.06
and the closing price on August 28, 1998 was $23.13, a 37.6% reduction].
Management of New 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 New 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

     Notwithstanding the foregoing, if the Exchange Closing Date is (a) on or
after August 16, 1998 but prior to September 30, 1998, then the First
Performance Period shall commence on September 1, 1998 and shall terminate on
(and including) December 31, 1998 and the Target EBITDA with respect thereto
shall be reduced to $6,700,000, or (b) 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

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 Holdco 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

     (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 is
expected to be confirmed by the bankruptcy court in early September 1998. Upon
the confirmation of the Plan of Reorganization and the closing of the Resurgens
Transaction, the creditors will receive shares of RCG common stock in exchange
for the surrender 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 New 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 New 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

TELCO PRO FORMA ADJUSTMENTS
 
     (E) The Telco 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 will be expensed at the consummation
of the acquisition. The amount of the one-time non-recurring charge is expected
to approximate $73.9 million. Since this charge is directly related to the
acquisition and will not recur, the Unaudited Pro Forma Statements of Earnings
have been prepared excluding this charge. New 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.

     (i) Based on the terms of the Telco Merger Agreement and the value of World
Access Common Stock as of August 28, 1998, Telco stockholders are currently
expected to receive approximately 6.5 million freely tradeable shares of New
World Access common stock at the time of the Telco Merger. The value assigned to
these shares will be $29.26 per share, the seven trading days average closing
price of World Access Common Stock which include the three trading days prior
and the three trading days subsequent to June 4, 1998, the date economic terms
of the Telco Merger were announced.
 
     (ii) The net deferred tax asset of $16 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
and New World Access. It is the opinion of management that these tax assets are
likely to be utilized by Telco or New World Access.
 
     (iii) The value of the acquired technology of $56.4 million is based on a
preliminary valuation report prepared by an independent appraiser and represents
the value of Telco's current technology calculated using the income approach.
 
     (iv) The amount of in-process research and development costs of $73.9
million is based on 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. New World Access will obtain an
updated valuation of the in-process research and development as of the closing
of the Telco Merger for use in determining the final purchase accounting for the
Telco Merger.

                             FIRST AMENDMENT TO THE
                AGREEMENT AND PLAN OF MERGER AND REORGANIZATION
 
     THIS FIRST AMENDMENT (the "Amendment") to the Agreement and Plan of Merger
and Reorganization (the "Merger Agreement;" capitalized terms used but not
defined herein shall have the meanings ascribed to them therein), dated as of
the 12th day of May, 1998, by and among WAXS INC., a Delaware corporation and a
direct wholly-owned subsidiary of World Access, Inc. ("New World Access"), WORLD
ACCESS, INC., a Delaware corporation ("World Access"), WA MERGER CORP., a
Delaware corporation and a direct wholly-owned subsidiary of New World Access
("Merger Sub"), and CHERRY COMMUNICATIONS INCORPORATED d/b/a RESURGENS
COMMUNICATIONS GROUP, an Illinois corporation ("RCG"), is made as of the 20th
day of July, 1998 by and among New World Access, World Access, Merger Sub and
RCG.
 
                                  WITNESSETH:
 
     WHEREAS, the Parties desire to amend the Merger Agreement as provided
herein,
 
     NOW, THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements herein, the parties hereto do hereby agree as follows:
 
     SECTION 1. Amendments to Merger Agreement.  The Merger Agreement is hereby
amended as follows:
 
          (a) Section 5.3 of the Merger Agreement is hereby amended and restated
     in its entirety as follows:
 
     "Section 5.3. Payment of Claims.  In accordance with the terms and
     provisions of the Plan and unless otherwise provided therein, the
     Disbursing Agent under the Disbursement Agreement shall issue to each
     holder of an Allowed Claim and an Administrative Expense Claim (including
     the Administrative Expense Claim of WNSI arising in connection with the DIP
     Financing), its pro-rata share of Disbursed Stock based upon the amount of
     such claim. The Disbursing Agent will return to New World Access shares of
     Disbursed Stock having a value that equals the dollar amount of Cash (as
     defined in the Plan) that the Reorganized Debtor (as defined in the Plan)
     or the Surviving Corporation must pay to holders of Allowed Priority Claims
     (including the principal amount of Priority Tax Claims) pursuant to the
     terms of the Plan where the value of such shares is based on $32.00 per
     share."
 
          (b) Article 5 of the Merger Agreement is hereby amended by adding the
     following additional Section 5.6 thereto which reads in its entirety as
     follows:
 
     "Section 5.6 Fractional Shares.  For purposes of distributions under the
     Plan, the number of shares of Disbursed Stock and Contingent Payment Stock
     shall, if necessary, be rounded to the next greater or lower whole number
     of shares as follows: (1) fractions of 1/2 or greater shall be rounded to
     the next greater whole number, and (2) fractions of less than 1/2 shall be
     rounded to the next lower whole number; provided, however, that to the
     extent that there are interim distributions, the numbers of shares of
     Disbursed Stock or Contingent Payment Stock shall be rounded to the next
     lower whole number for purposes of such distribution, and in the final
     distribution shall be rounded in accordance with the preceding clause based
     on the applicable aggregate number of shares of Disbursed Stock or
     Continent Payment stock distributed to each holder in all distributions.
     The total number of shares of Disbursed Stock or Contingent Payment stock
     shall be adjusted as necessary to account for the rounding provided hereby.
     No consideration shall be payment in lieu of the fractions shares that are
     rounded down."
 
          (c) Section 6.4 of the Merger Agreement is hereby amended and restated
     in its entirety as follows:
 
     "Section 6.4. Transfer Restrictions.  Notwithstanding anything to the
     contrary contained herein, (a) no holder of Disbursed Stock may, until the
     365th day following the Closing Date, without the prior written consent of
     New World Access, offer, sell, contract to sell or otherwise dispose of,
     directly or indirectly, any shares of Disbursed Stock or security
     convertible into or exchangeable or exercisable therefor, either publicly
     or privately, (b) no holder of Contingent Payment Stock upon its release
     pursuant to Section 6.1
                                      M-69
<PAGE>   790
 
     above may, until the 180th day following the release date thereof, without
     the prior written consent of New World Access, offer, sell, contract to
     sell or otherwise dispose of, directly or indirectly, any shares of the
     Contingent Payment Stock so released or any security convertible into or
     exchangeable or exercisable therefor, either publicly or privately, and (c)
     until the third anniversary of the Closing Date, no holder of Disbursed
     Stock or Contingent Payment Stock may engage in any short-sale or similar
     type of transaction with respect to any shares of World Access Stock,
     including any shares of Disbursed Stock or Contingent Payment Stock,
     without the prior written consent of New World Access; provided, however,
     that holders of Claims (as defined in the Plan) may buy and sell to each
     other their respective shares of Disbursed Stock or Contingent Payment
     Stock, subject to applicable securities laws."
 
          (d) The Merger Agreement is hereby amended by adding a new Section 6.5
     thereto which shall read in its entirety as follows:
 
     "Section 6.5. Waiver of Restrictions.  New World Access agrees that if it
     waives any of the transfer restrictions set forth in Section 6.4 with
     respect to any holder of Disbursed Stock or Contingent Payment Stock,
     including WNSI, or in Section 4.4 of the U.K. Acquisition Agreement with
     respect to the Shareholder (as defined in the U.K. Acquisition Agreement),
     then New World Access will give notice of such waiver within five (5) days
     to all other holders of Disbursed Stock or Contingent Payment Stock (and
     such other persons as the Plan may specify) and transfer restrictions with
     respect to all such holders shall be deemed immediately waived (without any
     further action) as to such other holders in the same pro rata amount as
     such waiver affirmatively granted by New World Access in respect of the
     holder or the Shareholder (as the case may be); provided, however, the
     provisions of this Section 6.5 shall not apply with respect to any
     transfers by the Shareholder or its partners to charitable institutions or
     for estate planning purposes, provided that the transferee agrees to be
     bound by the transfer restrictions set forth in Section 4.4 of the U.K.
     Acquisition Agreement. New World Access agrees to promptly instruct its
     transfer agent to reissue certificates for, or remove any stop transfer
     instructions with respect to, any shares of Disbursed Stock or Contingent
     Payment Stock as to which the transfer restrictions have been deemed waived
     in accordance with this Section 6.5."
 
     SECTION 2. Effect on Merger Agreement.  Except as otherwise specifically
provided herein, the Merger Agreement shall not be amended but shall remain in
full force and effect.
 
     SECTION 3. Headings.  The Section headings contained in this Amendment are
for reference purposes only and will not affect in any way the meaning or
interpretation of this Amendment.
 
     SECTION 4. Counterparts.  This Amendment may be executed simultaneously in
counterparts, each of which will be deemed an original, but all of which
together will constitute one and the same instrument.

     IN WITNESS WHEREOF, each of the Parties has caused this Amendment to be
executed and delivered by their respective officers thereunto duly authorized,
all as of the day and year above written.

        RCG. World Access and its Affiliates shall cooperate in connection with
        preparing, filing and obtaining the approval of the Plan and the Plan
        Disclosure Statement. The Plan shall provide, inter alia, for (a) the
        cancellation of all outstanding shares of RCG Stock other than Creditor
        Shares without the payment of any consideration therefor; (b) the
        issuance of 3,125,000 shares of RCG Stock (collectively, the "Creditor

        Administrative Expense Claims (including the Administrative Expense
        Claim of WNSI arising in connection with the DIP Financing); (c) the
        approval of this Agreement; (d) except as otherwise provided in the
        Plan, the discharge of all other indebtedness of and claims against RCG

        Merger and the resulting pro-rata distribution of Disbursed Stock and
        the right to receive (if released pursuant to Article 6 hereof) the
        Contingent Payment Stock in exchange for all outstanding Creditor
        Shares; and (f) certain transfer restrictions on the shares of New World
        Access Stock to be issued pursuant to this Agreement as set forth in
        Section 6.4 hereof. RCG estimates that the aggregate amount of Allowed
        Claims will be approximately $300,000,000 to $350,000,000.
 
             Section 5.2 Deposit of New World Access Stock.  At the Closing, New
        World Access and the Person appointed by the Bankruptcy Court pursuant
        to the Plan and the Order to act as "Disbursing Agent" under the Plan
        (the "Disbursing Agent") shall each execute a Disbursement Agreement
        reasonably acceptable to the Parties hereto and, in accordance
        therewith, New World Access shall deposit with the Disbursing Agent,
        immediately following the Effective Time, an aggregate of 9,375,000

        provisions of the Plan and unless otherwise provided therein, (a) RCG
        shall be deemed to have issued to each holder of an Allowed Claim and an
        Administrative Expense Claim (including the Administrative Expense Claim
        of WNSI arising in connection with the DIP Financing) its pro-rata share
        of the Creditor Shares based upon the amount of each such claim in
        exchange for the surrender of such claims, and (b) immediately after the
        cancellation of all other outstanding RCG Stock and the issuance of the
        Creditor Shares, the Disbursing Agent under the Disbursement Agreement
        shall issue to each holder of Creditor Shares its pro-rata share of
        Disbursed Stock based upon the number of Creditor Shares held by each
        such holder. The Disbursing Agent will return to New World Access shares
        of Disbursed Stock equal to (x) the dollar amount of all Cash (as
        defined in the Plan) that the Reorganized Debtor (as defined in the
        Plan) or the Surviving Corporation must pay to holders of Allowed
        Priority Claims (including the principal amount of Priority Tax Claims)
        pursuant to the terms of the Plan, divided by (y) $32.00.

        shall release to holders of Creditor Shares their pro-rata share of
        Contingent Payment Stock, if, as, when and to the extent that the
        Contingent Payment Stock (or any portion thereof) is released pursuant
        to the terms of Article 6 hereof in accordance with the terms and
        provisions of the Plan.
 
             Section 5.5 Fractional Shares.  For purposes of distributions under
        the Plan, the number of shares of Disbursed Stock and Contingent Payment
        Stock shall, if necessary, be rounded to the next greater or lower whole
        number of shares as follows: (a) fractions of 1/2 or greater shall be
        rounded to the next greater whole number; and (b) fractions of less than
        1/2 shall be rounded to the next lower whole number; provided, however,
        that to the extent that there are interim distributions, the number of
        shares of Disbursed Stock or Contingent Payment Stock shall be rounded
        to the next lower whole number for purposes of such distribution and in
        the final distribution shall be rounded in accordance with the
        immediately preceding clause based on the applicable aggregate number of
        shares of Disbursed Stock or Contingent Payment Stock distributed to
        each holder in all distributions. The total number of shares of
        Disbursed Stock or Contingent Payment Stock shall be adjusted as
                                      M-73

        necessary to account for the rounding provided hereby. No consideration
        shall be paid in lieu of fractional shares that are rounded down."
 
          (d) Section 9.4 of the Merger Agreement is hereby amended and restated
     in its entirety as follows:
 
             "Section 9.4 Approval of Stockholders of World Access.  World
        Access will take all steps necessary under applicable law and its
        certificate of incorporation and bylaws to call, give notice of, convene
        and hold a meeting of its stockholders for the purpose of approving this
        Agreement and the Merger and for such other purposes consistent with the
        complete performance of this Agreement as may be necessary or desirable.
        Unless the Board of Directors of World Access determines in good faith,
        based upon advice of its outside counsel, that such recommendation would
        violate its fiduciary duties to its stockholders, the Board of Directors
        of World Access will recommend to its stockholders the approval of this
        Agreement, the Merger and the transactions contemplated hereby and will
        use its best efforts to obtain the necessary approvals by its
        stockholders of this Agreement, the Merger and the transactions
        contemplated hereby. Notwithstanding anything herein to the contrary, it
        is understood that the approval of this Agreement, the Merger and the
        transactions contemplated hereby by the World Access stockholders is
        intended to constitute the requisite approval of the New World Access
        stockholders."
 
     SECTION 2. Effect on Merger Agreement.  Except as otherwise specifically
provided herein, the Merger Agreement shall not be amended but shall remain in
full force and effect.
 
     SECTION 3. Headings.  The Section headings contained in this Second
Amendment are for reference purposes only and will not affect in any way the
meaning or interpretation of this Second Amendment.
 
     SECTION 4. Counterparts.  This Second Amendment may be executed
simultaneously in counterparts, each of which will be deemed an original, but
all of which together will constitute one and the same instrument.

be executed and delivered by its respective officer thereunto duly authorized,
all as of the day and year above written.

SUMMARY: U.S. BANKRUPTCY COURT CONFIRMS RESURGENS REORGANIZATION PLAN
 
FOR IMMEDIATE RELEASE
 
Atlanta, Georgia -- September 3, 1998 -- WORLD ACCESS, INC. (NASDAQ: WAXS)
announced today that the United States Bankruptcy Court of the Northern District
of Illinois, Eastern Division, has confirmed the Plan of Reorganization (the
"Plan") of Cherry Communications Incorporated, d/b/a Resurgens Communications
Group ("Resurgens"). The Plan incorporates the terms of the definitive agreement
entered into earlier this year by World Access to acquire Resurgens, a
facilities-based provider of international network access.
 
Steven A. Odom, Chairman and Chief Executive Officer, said "The confirmation of
the Plan satisfies a significant condition to the consummation of the Resurgens
acquisition, which is expected to occur in the near future. This acquisition
will uniquely position World Access to offer telecommunications service
providers a complete network solution, including proprietary equipment, planning
and engineering services and access to international long distance. The
international network access offered by Resurgens is a critical element of new
and expanded networks currently being planned or implemented by many of our
customers. World Access is beginning to realize significant synergies as a
result of the Resurgens acquisition, including equipment sales to Resurgens
customers, potential joint ventures with international PTTs and CLECs, and
carrier service revenues form World Access equipment customers."
 
John D. Phillips, Chairman and Chief Executive Officer of Resurgens, commented
"We are extremely pleased that Resurgens' creditors have embraced our plan of
reorganization, an integral part of which is the merger with World Access. We
have rebuilt Resurgens' operating network and implemented new, reliable billing
systems and a 24 hour-7 day Network Operations Center. Competitive, dedicated
bandwidth and transit agreements are now in place to carry traffic to all key
regions of the world and Resurgens is now carrying extensive international
traffic for WorldCom and numerous other long-distance companies."
 
World Access, Inc. develops, manufactures and markets wireline and wireless
switching, transport and access products for the global 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, 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. 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.
 
     EXCEPT FOR ANY HISTORICAL INFORMATION CONTAINED HEREIN, THE MATTERS
     DISCUSSED IN THIS PRESS RELEASE CONTAIN FORWARD-LOOKING STATEMENTS

announced holding company reorganization shall have been consummated on or
before the time of the Merger, New World Access common stock, $.01 par value per
share ("New World Access Common Stock") (in either case, the "Merger Common
Stock"), equal to the quotient of $17.00 divided by the average daily closing
price of World Access 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 Merger 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 Merger Common Stock.
 
     The Merger is intended to constitute a tax-free reorganization under
Section 368(a) of the Internal Revenue Code of 1986, as amended, and will be
accounted for as a purchase. The consummation of the Merger is subject to (i)
clearance under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
amended, (ii) the approval by the respective stockholders of World Access (or
New World Access, as the case may be) and Telco, (iii) the approval by the
stockholders of World Access (or New World Access, as the case may be) of an
increase in the authorized shares of common stock of such corporation, and (iv)
the satisfaction or waiver of customary conditions.
 
     In connection with the Merger Agreement, Kopp Investment Advisors, Inc. and
the directors and certain executive officers of Telco entered into a
Stockholders Proxy Agreement with New World Access pursuant to which, among
other things, they agreed to vote an aggregate of approximately 8.0% of the
outstanding shares of Telco Common Stock in favor of the Merger.
 
     The foregoing description of the Merger, the Merger Agreement and the
Stockholders Proxy Agreement is qualified in its entirety by reference to the
Merger Agreement and the Stockholders Proxy Agreement, which have been filed as
exhibits to World Access' Form 8-K filed with the Securities and Exchange
Commission on June 8, 1998.
 
ITEM 7.  FINANCIAL STATEMENTS, PRO FORMA FINANCIAL INFORMATION AND EXHIBITS
 
     (a) Financial Statements of Business Acquired.  Included in this report are
the following financial statements:
 
          (i) The unaudited consolidated financial statements of Telco Systems,
     Inc ("Telco") for the three months and nine months in each of the periods
     ended May 31, 1998 and 1997; and
 
          (ii) The audited consolidated financial statements of Telco for the
     year ended August 31, 1997, which have been audited by the independent
     accounting firm of Ernst & Young LLP, whose opinion thereon is included
     herein.
 
     (b) Pro Forma Financial Information.  The Unaudited Pro Forma Combined
Financial Statements of New World Access give effect to the consummation of the
several transactions that World Access has completed or that are currently
contemplated. The Unaudited Pro Forma Combined Statements of Operations give
effect to: (1) the acquisition of Advanced TechCom, Inc. ("ATI"), which was
consummated on January 29, 1998; (2) the acquisition of a 67.3% majority
interest in NACT Telecommunications, Inc. ("NACT") (the "NACT Stock Purchase"),
which was consummated on February 27, 1998; (3) the
 
                                       N-1
<PAGE>   802
 
acquisition of the remainder of NACT (the "NACT Merger"); (4) the acquisition of
Cherry Communications Incorporated (d/b/a Resurgens Communications Group) and
Cherry Communications U.K. Limited (collectively 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
Merger, the Resurgens Transaction and the Merger as if they had been completed
on June 30, 1998.
 
     As Telco's fiscal year end, August 31, differs from World Access' fiscal
year-end by more than 93 days, Telco's 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's results of operations for the six months from December 1, 1997 through
May 31, 1998 were used in preparing the Unaudited Pro Forma Combined Statement
of Operations for the six months ended June 30, 1998. Telco's 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 acquisition
transactions, New World Access expects to record charges representing the
estimated portion of the purchase price allocated to in-process research and
development of $21.9 million and $73.9 million for the NACT Merger and the
Merger, respectively. In addition, in the three month period ended March 31,
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.
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 World Access, ATI, NACT, and Telco, the
historical combined financial statements of Resurgens and the related notes
thereto.

                         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 31, 1997 and August 25, 1996, and the related
consolidated statements of operations, shareholders' equity, and cash flows for
each of the three years in the period ended August 31, 1997. 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 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 31, 1997, and August 25, 1996, and the
consolidated results of its operations and its cash flows for each of the three
years in the period ended August 31, 1997, in conformity with generally accepted
accounting principles.

                   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 53 weeks in fiscal 1997 and 52 weeks in both fiscal 1996 and
fiscal 1995. 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 7).
 
  New Accounting Standards
 
     In February 1997, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards 128 (SFAS 128), "Earnings Per Share"
which will require adoption in the Company's second quarter of fiscal 1998. This
statement specifies the computation, presentation and disclosure requirements of
earnings per share. The Company believes that adoption of this statement will
have no material impact on its consolidated financial statements and related
disclosures.
 
     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 is in the
process of determining the effect of adoption of this statement on its
consolidated financial statements and related disclosures. 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.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
  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 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.
 
     Inventories at fiscal year end were as follows:

  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
$7,122,000 and $7,791,000 at August 31, 1997 and August 25, 1996, respectively.
They are amortized over lives ranging from seven to twenty-five years using the
straight-line method, with an average remaining life of 10.7 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.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
  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
 
     Earnings (loss) per share is based on the weighted average number of common
shares outstanding and common stock equivalents, if dilutive. Fully diluted
earnings per share did not differ significantly from primary earnings per share
in any year. Net loss per share in fiscal years 1997 and 1996 did not consider
common stock equivalents as the effect would be antidilutive.
 
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 39% of sales
in fiscal 1997, 37% of sales in fiscal 1996, and 29% of sales in fiscal 1995.
RBOC sales include sales to one RBOC of 33% in fiscal 1997, 31% in fiscal 1996,
and 17% in fiscal 1995. 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. In fiscal 1995, one additional customer
represented 18% of sales.

     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. The valuation reserve increased by $1,946,000 in fiscal
1997. This change is due primarily to an increase in the current year of
inventory and other reserves. These items have been fully reserved.
 
     At August 31, 1997, the Company had net operating loss carryforwards to
reduce future taxable income of $5,000,000. To the extent not utilized, the U.S.
Federal net operating loss will expire in 2011. The Company also had unused

NOTE 7  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. All of equipment included in the
transaction was purchased by the Company within the last eighteen months.
 
     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 31, 1997 are set forth in the following
table. Amounts relating to excess facilities included herein have been accrued
as discussed in Note 8:

     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 plan was accomplished within
original cost estimates. At August 31, 1997, the remaining reserve balance of
$1,657,000 was specifically designated for excess facility costs at the Fremont,
California location.
 
     At August 31, 1997, the remaining fiscal 1993 restructuring reserve for

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 31, 1997,
1,479,786 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 15, 1996, 92,000 restricted shares of the Company's common
stock were granted and 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 certain restrictions and forfeiture provisions. At
August 31, 1997, 7,500 shares carried restrictions. Restrictions on the shares
expire ratably on the anniversary date of the award over the next three years.

     At August 31, 1997, August 25, 1996, and August 27, 1995, there were
464,589 shares, 464,767 shares, and 413,495 shares exercisable, respectively.
 
     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.
There were 38,947 shares issuable under the Plan for fiscal 1997 of which 22,112
were outstanding at August 31, 1997. For fiscal 1996 and 1995, 56,010 shares and

     In October 1995, the Financial Accounting Standards Board issues 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 $468,000 in fiscal 1997, $547,000 in
fiscal 1996, and $525,000 in fiscal 1995.
 
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.

NOTE 1 -- BASIS OF PRESENTATION
 
     The consolidated financial statements of Telco Systems, Inc. (the
"Company") included in this report reflect all adjustments (consisting of only
normally recurring accruals) which, in the opinion of management, are necessary
for a fair presentation of the consolidated financial position at May 31, 1998
and the consolidated statements of operations and cash flows for the nine months
ended May 31, 1998 and May 25, 1997. The unaudited results of operations for the
interim periods reported are not necessarily indicative of results to be
expected for the year.
 
     Certain notes and other information have been condensed or omitted from
these interim financial statements. The statements, therefore, should be read in
conjunction with the consolidated financial statements and related notes
included in the Telco Systems, Inc. Annual Report on Form 10-K for the year
ended August 31, 1997.

NOTE 4 -- ACQUISITION
 
     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 the third quarter of fiscal 1998. In addition, the purchase price
included $1.1 million of goodwill, which will be amortized over five years.

NOTE 5 -- (LOSS) EARNINGS PER SHARE
 
     In February 1997, the Financial Accounting Standards Board issued Statement
No. 128, "Earnings per Share", 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 common 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. The following table reconciles the number of shares
utilized in the earnings per share calculations for the periods ended May 31,
1998 and May 25, 1997.

NOTE 6 -- SUBSEQUENT EVENT
 
     On June 4, 1998, the Company entered into a definitive agreement to merge
with World Access, Inc. The transaction will be subject to stockholder and
regulatory approval and is expected to be accounted for as a purchase. The
merger agreement provides that all shares of the Company's common stock will be
converted into shares of World Access common stock having a value of $17.00 per
share, 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.

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 New 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, 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
July 9, 1998, World Access, GST and Aerotel entered into a Memorandum of
Understanding to settle the Aerotel litigation. Including legal fees, World
Access now estimates its Aerotel settlement costs will be approximately $3.3
million. The settlement costs expected to be incurred by World Access 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 New 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

   NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
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.
 
     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 included significant
redevelopment of some existing products and the creation of new products. 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.
 
     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.  Telco develops and manufactures products focused on providing
integrated access for network services. Telco's products can be separated into
three categories: (1) broadband transmission products, (2) network access
products, and (3) bandwidth optimization products. Telco's 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 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's 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's in process research
and development are expected to include interface support not in Telco's current
product line, including E1, DS3 and OC3.
 
     None of the in-process projects at Telco considered in the write-off are
expected to achieve technological feasibility before the consummation of World
Access' acquisition of Telco. 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's 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's old products by these new products as well as the
expected growth in the overall market in which Telco's 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 (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 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. New
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 net assets acquired is
determined as follows (in thousands):

based on the valuation performed in connection with the NACT Stock Purchase. The
valuation report assigned a value of $66.5 million to the in-process research
and development projects as of the date of the NACT Stock Purchase, of which
67.3% or $44.6 million was expensed at the consummation of the NACT Stock
Purchase. Management estimates that an additional $21.9 million of in-process
research and development projects will be written-off in conjunction with the

     (i) Represents an estimate of $1.0 million to be paid to the creditors of
Resurgens under a cash settlement plan proposed by New World Access and
approximately $2.0 million to be paid to governmental creditors.
 
     (ii) The value assigned to the 3,750,000 restricted New 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 New 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. New 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 New
World Access common stock [the closing price on the announcement date was $37.06
and the closing price on August 28, 1998 was $23.13, a 37.6% reduction].
Management of New 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 New 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

     Notwithstanding the foregoing, if the Exchange Closing Date is (a) on or
after August 16, 1998 but prior to September 30, 1998, then the First
Performance Period shall commence on September 1, 1998 and shall terminate on
(and including) December 31, 1998 and the Target EBITDA with respect thereto
shall be reduced to $6,700,000, or (b) 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 Holdco 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 is
expected to be confirmed by the bankruptcy court in early September 1998. Upon
the confirmation of the Plan of Reorganization and the closing of the Resurgens
Transaction, the creditors will receive shares of RCG common stock in exchange
for the surrender 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 New 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 New 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 PRO FORMA ADJUSTMENTS
 
     (E) The Telco 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 will be expensed at the consummation
of the acquisition. The amount of the one-time non-recurring charge is expected
to approximate $73.9 million. Since this charge is directly related to the
acquisition and will not recur, the Unaudited Pro Forma Statements of Earnings
have been prepared excluding this charge. New 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.

     (i) Based on the terms of the Telco Merger Agreement and the value of World
Access Common Stock as of August 28, 1998, Telco stockholders are currently
expected to receive approximately 6.5 million freely tradeable shares of New
World Access common stock at the time of the Telco Merger. The value assigned to
these shares will be $29.26 per share, the seven trading days average closing
price of World Access Common Stock which include the three trading days prior
and the three trading days subsequent to June 4, 1998, the date economic terms
of the Telco Merger were announced.
 
     (ii) The net deferred tax asset of $16 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
and New World Access. It is the opinion of management that these tax assets are
likely to be utilized by Telco or New World Access.
 
     (iii) The value of the acquired technology of $56.4 million is based on a
preliminary valuation report prepared by an independent appraiser and represents
the value of Telco's current technology calculated using the income approach.
 
     (iv) The amount of in-process research and development costs of $73.9
million is based on 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. New World Access will obtain an
updated valuation of the in-process research and development as of the closing
of the Telco Merger for use in determining the final purchase accounting for the
Telco Merger.

ITEM 1.  DESCRIPTION OF REGISTRANT'S SECURITIES TO BE REGISTERED
 
     A. Units
 
     Each Unit consists of one share of Common Stock, $.01 par value and one
Warrant.
 
     B. Common Stock
 
The holders of Common Stock are entitled to one vote for each share held of
record on all matters to be voted on by stockholders. There is no cumulative
voting with respect to the election of directors, with the result that the
holders of more than 50% of the shares voted for the election of directors can
elect all of the directors. The holders of Common Stock are entitled to receive
dividends when, as and if declared by the board of directors out of funds
legally available therefor. The Company is currently precluded from paying
dividends by an agreement with its principal lender and, if this provision were
eliminated, has no intent to pay dividends in the foreseeable future. In the
event of liquidation, dissolution or winding up of the Company, the holders of
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 Common Stock.
Holders of shares of Common Stock, as such have no conversion, preemptive or
other subscription rights, and there are no redemption provisions applicable to
the Common Stock. All of the outstanding shares of Common Stock are validly
issued, fully paid and nonassessable.
 
     C. Warrants
 
     Commencing August 12, 1992 and for a two-year period thereafter, each two
Warrants will entitle the registered holder to purchase one share of the
Company's Common Stock at an exercise price of $9.50 per share. No fractional
shares of Common Stock will be issued in connection with the exercise of
Warrants. Upon exercise the Company will pay the holder the value of any such
fractional shares based upon the market value of the Common Stock at such time.
 
     The Company may redeem the Warrants at a price of $.01 per Warrant at any
time prior to their expiration by giving 30 to 60 days' written notice mailed to
the record holders at any time after one year from the Effective Date if the
average of the closing bid and asked prices of the Common Stock as quoted by
NASDAQ (or the last sale price if listed on a national securities exchange)
exceeds $11.00 per share for a period of each of 20 consecutive trading days
during a period ending within 10 trading days prior to the date of mailing of
notice of redemption.
 
     Unless extended by the Company at its discretion, the Warrants will expire
at 4:00 p.m. New York time on August 12, 1994.
 
     The holder of Warrants will not have any rights, privileges or liabilities
of a stockholder of the Company prior to exercise of such Warrants. The Company
shall keep available a sufficient number of unauthorized shares of Common Stock
to permit exercise of the Warrants.

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.

     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.

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

     (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.

or may be without voting powers; (b) may be subject to redemption at such time
or times and at such prices; (c) may be entitled to receive dividends (which may

all as shall be stated in said resolution or resolutions providing for the issue
of such shares of Preferred Stock. Shares of Preferred Stock of any series that
have been redeemed (whether through the operation of a sinking fund or
otherwise) or that, if convertible or exchangeable, have been converted into or
exchanged for shares of any other class or classes shall have the status of
authorized and unissued shares of Preferred Stock of the same series and may be
reissued as a part of the series of which they were originally a part or may be
reclassified and reissued as part of a new series of shares of Preferred Stock
to be created by resolution or resolutions of the Board of Directors or as part
of any other series of shares of Preferred Stock, all subject to the conditions
or restrictions on issuance set forth in the resolution or resolutions adopted
by the Board of Directors providing for the issue of any series of shares of
Preferred Stock.

         Subject to the provisions of any applicable law or of the Bylaws of the
corporation, as from time to time amended, with respect to the closing of the
transfer books or the fixing of a record date for the determination of
stockholders entitled to vote and except as otherwise provided by law or by the
resolution or resolutions providing for the issue of any series of shares of
Preferred Stock or any shares of a series of Common Stock as to which the voting
powers have been expressly limited by the resolution or resolutions providing
for the issuance of such series of Common Stock, the holders of outstanding
shares of Common Stock shall exclusively possess voting power for the election
of directors and for all other purposes, each holder of record of shares of
Common Stock being entitled to one vote for each share of Common Stock standing
in his or her name on the books of the corporation. Except as otherwise provided
by the resolution or resolutions providing for the issue of any series of shares
of Preferred Stock, the holders of shares of Common Stock shall be entitled, to
the exclusion of the holders of

shares of Preferred Stock of any and all series, to receive such dividends as
from time to time may be declared by the Board of Directors. In the event of any
liquidation, dissolution or winding up of the corporation, whether voluntary or
involuntary, after payment shall have been made to the holders of shares of
Preferred Stock of the full amount to which they shall be entitled pursuant to
the resolution or resolutions providing for the issue of any series of shares of
Preferred Stock, the holders of shares of Common Stock shall be entitled, to the
exclusion of the holders of shares of Preferred Stock of any and all series, to
share, ratably according to the number of shares of Common Stock held by them,
in all remaining assets of the corporation available for distributions to its
stockholders.

         Subject to the provisions of this Certificate of Incorporation and
except as otherwise provided by law, the stock of the corporation, regardless of
class, may be issued for such consideration and for such corporate purposes as
the Board of Directors may from time to time determine.

                                   ARTICLE VII

                                    Duration

         The corporation is to have perpetual existence.


                                  ARTICLE VIII

                             Action by Stockholders

         No action required or permitted to be taken by the stockholders of the
corporation at any annual or special meeting of the stockholders of the
corporation may be taken without a meeting, and the power to consent in writing,
without a meeting, to the taking of any action is specifically denied.

                                   ARTICLE IX

                                   Management

         1.       The business and affairs of the corporation shall be managed
by or under the direction of a Board of Directors.

                  (a)      The Board of Directors shall consist of not fewer
         than three (3) members and not more than twelve (12) members, the exact
         number of authorized directors within such range to be fixed from time
         to time by a resolution of the Board of Directors



                                       4
<PAGE>   5


         adopted by the affirmative vote of at least a majority of the total
         number authorized directors most recently fixed by the Board of
         Directors.

                  (b)      The directors of the corporation shall be divided
         into three classes for the purpose of determining their terms of
         office. Each such class shall consist, as nearly as possible, of
         one-third of the total number of directors fixed by the Board of
         Directors. At the annual meeting of stockholders of the corporation
         held in 1998, one class of directors (designated as Class I) shall be
         elected for a term expiring at the annual meeting of stockholders of
         the corporation held in 1999, one class of directors (designated as
         Class II) shall be elected for a term expiring at the annual meeting of
         stockholders of the corporation held in 2000, and one class of
         directors (designated as Class III) shall be elected for a term
         expiring at the annual meeting of stockholders of the corporation held
         in 2001. At each succeeding annual meeting of stockholders of the
         corporation, beginning in 1999, successors to the class of directors
         whose term expires at that annual meeting shall be elected for a term
         expiring at the annual meeting of stockholders of the corporation held
         in the third year of their election.

                  (c)      If the number of directors is changed, then any
         increase or decrease in such number shall be apportioned by the Board
         of Directors among the classes of directors so as to maintain as nearly
         as possible an equal number of directors in each class. No reduction in
         the authorized number of members of the Board of Directors shall have
         the effect of removing any director from office before the director's
         term of office expires.

                  (d)      Vacancies on the Board of Directors and newly created
         directorships resulting from an increase in the authorized number of
         members of the Board of Directors may be filled only by a majority of
         the directors then in office, although less than a quorum, or by a sole
         remaining director.

                  (e)      Each director, including a director elected to fill a
         vacancy or a newly created directorship, shall hold office until the
         next election of the class of directors to which such director belongs
         and until his or her successor is elected and qualified or until his or
         her earlier death, resignation, or removal from office for cause.

                  (f)      Any director or the entire Board of Directors may be
         removed from office at any time but 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 of the corporation
         then entitled to vote in an election of directors of the corporation,
         voting as a single class.

                  (g)      A majority of total directors shall constitute a
         quorum for the transaction of business.

                  (h)      Notwithstanding the foregoing, whenever the holders
         of any one or more classes or series of stock issued by the corporation
         shall have the right, voting separately by class or series, to elect
         directors at an annual or special meeting of stockholders, the
         election, term of office, filling of vacancies and other features of
         such directorships shall



                                       5
<PAGE>   6


         be governed by the terms of this Certificate of Incorporation
         applicable thereto, such directors so elected shall not be divided into
         classes pursuant to this Article IX, and the number of such directors
         shall not be counted in determining the maximum number of directors
         permitted under the foregoing provisions of this Article IX, in each
         unless expressly provided by such terms.

         2.       Nominations of persons for election to the Board of Directors
may be made at a meeting of stockholders of the corporation either by or at the
direction of the Board of Directors or by any stockholder of record entitled to
vote in the election of directors at such meeting who has complied with the
notice procedures set forth in this Paragraph 2. A stockholder who desires to
nominate a person for election to the Board of Directors at a meeting of
stockholders of the corporation and who is eligible to make such nomination must
give timely written notice of the proposed nomination to the secretary of the
corporation. To be timely, a stockholder's notice given pursuant to this
Paragraph 2 must be received at the principal executive office of the
corporation not less than one hundred twenty (120) calendar days in advance of
the date which is one year later than the date of the proxy statement of the
corporation released to stockholders in connection with the previous year's
annual meeting of stockholders of the corporation; provided, however, that if no
annual meeting of stockholders of the corporation was held in the previous year
or if the date of the forthcoming annual meeting of stockholders has been
changed by more than thirty (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 of the corporation, 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 the corporation or (b) the day on which public disclosure of the date of the
forthcoming meeting was made by or on behalf of the corporation. Such
stockholder's notice to the secretary of the corporation shall set forth (a) as
to each person whom the stockholder proposes to nominate for election or
re-election as a director (i) the name, age, business address and residence
address of such person, (ii) the principal occupation or employment of such
person, (iii) the class and number of shares of capital stock of the corporation
which then are beneficially owned by such person, (iv) any other information
relating to such person that is required by law or regulation to be disclosed in
solicitations of proxies for the election of directors of the corporation, and
(v) such person's written consent to being named as a nominee for election as a
director and to serve as a director if elected and (b) as to the stockholder
giving the notice (i) the name and address, as they appear in the stock records
of the corporation, of such stockholder, (ii) the class and number of shares of
capital stock of the corporation which then are beneficially owned by such
stockholder, (iii) a description of all arrangements or understandings between
such stockholder and each nominee for election as a director and any other
person or persons (naming such person or persons) relating to the nomination
proposed to be made by such stockholder, and (iv) any other information required
by law or regulation to be provided by a stockholder intending to nominate a
person for election as a director of the corporation. At the request of the
Board of Directors, any person nominated by or at the direction of the Board of
Directors for election as a director of the corporation shall furnish to the
secretary of the corporation the information concerning such nominee which is
required to be set forth in a stockholder's notice of a proposed nomination. No
person shall be eligible for election as a director of the corporation unless
nominated in compliance with the procedures set forth in this Paragraph 2. The
chairman of a meeting of stockholders of the corporation shall



                                       6
<PAGE>   7


refuse to accept the nomination of any person not made in compliance with the
procedures set forth in this Paragraph 2, and such defective nomination shall be
disregarded.

         3.       The power to adopt, amend or repeal the Bylaws of the
corporation may be exercised by the Board of Directors of the corporation.

         4.       Notwithstanding any provision of this Certificate of
Incorporation or the Bylaws of the corporation to the contrary, the affirmative
vote of the holders of at least seventy-five percent (75%) of the voting power
of all outstanding shares of capital stock of the corporation then entitled to
vote in an election of directors of the corporation, voting as a single class,
shall be required to alter, amend or repeal this Article IX or to adopt any
provision of this Certificate of Incorporation or the Bylaws of the corporation
which is inconsistent with this Article IX.

                                    ARTICLE X

                             Limitation of Liability

         The personal liability of the directors of the corporation is hereby
eliminated to the fullest extent permitted by paragraph (7) of subsection (b) of
ss. 102 of the General Corporation Law of the State of Delaware, as the same may
be amended and supplemented.

                                   ARTICLE XI

                                 Indemnification

         The corporation shall, to the fullest extent permitted by ss. 145 of
the General Corporation Law of the State of Delaware, as the same may be amended
and supplemented, indemnify any and all persons whom it shall have power to
indemnify under said section from and against any and all of the expenses,
liabilities, or other matters referred to in or covered by said section, and the
indemnification provided for herein shall not be deemed exclusive of any other
rights to which those indemnified may be entitled under any Bylaw, agreement,
vote of stockholders or disinterested directors or otherwise, both as to action
in his official capacity and as to action in another capacity while holding such
office, and shall continue as to a person who has ceased to be a director,
officer, employee, or agent and shall inure to the benefit of the heirs,
executors, and administrators of such a person.

                                   ARTICLE XII

                                    Amendment

         From time to time any of the provisions of this Certificate of
Incorporation may be amended, altered, or repealed, and other provisions
authorized by the laws of the State of Delaware at the time in force may be

rights at any time conferred upon the stockholders of the corporation by this
Certificate of Incorporation are granted subject to the provisions of this
Article XII.

                                    WAXS INC.

                            (a Delaware corporation)

                         Adopted as of February 23, 1998


                                    ARTICLE I

                                  STOCKHOLDERS

                  1.       CERTIFICATES REPRESENTING STOCK. Certificates
representing stock in the Corporation shall be signed by, or in the name of, the
Corporation by the Chairman or Vice-Chairman of the Board of Directors, if any,
or by the President or a Vice-President and by the Treasurer or an Assistant
Treasurer or the Secretary or an Assistant Secretary of the Corporation. Any or
all the signatures on any such certificate may be a facsimile. in case any
officer, transfer agent, or registrar who has signed or whose facsimile
signature has been placed upon a certificate shall have ceased to be such
officer, transfer agent, or registrar before such certificate is issued, it may
be issued by the Corporation with the same effect as if he were such officer,
transfer agent, or registrar at the date of issue.

                  Whenever the Corporation shall be authorized to issue more
than one class of stock or more than one series of any class of stock, and
whenever the Corporation shall issue any shares of its stock as partly paid
stock, the certificates representing shares of any such class or series or of
any such partly paid stock shall set forth thereon the statements prescribed by
the General Corporation Law. Any restrictions on the transfer or registration of
transfer of any shares of stock of any class or series shall be noted
conspicuously on the certificate representing such shares.

                  The Corporation may issue a new certificate of stock or
uncertificated shares in place of any certificate theretofore issued by it,
alleged to have been lost, stolen, or destroyed, and the Board of Directors may
require the owner of the lost, stolen, or destroyed certificate, or his legal
representative, to give the Corporation a bond sufficient to indemnify the
Corporation against any claim that may be made against it on account of the
alleged loss, theft, or destruction of any such certificate or the issuance of
any such new certificate or uncertificated shares.

                  2.       UNCERTIFICATED SHARES. Subject to any conditions
imposed by the General Corporation Law, the Board of Directors of the
Corporation may provide by resolution or resolutions that some or all of any or
all classes or series of the stock of the Corporation shall be uncertificated
shares. Within a reasonable time after the issuance or transfer of any


<PAGE>   2



uncertificated shares, the Corporation shall send to the registered owner
thereof any written notice prescribed by the General Corporation Law.

                  3.       FRACTIONAL SHARE INTERESTS. The Corporation may, but
shall not be required to, issue fractions of a share. If the Corporation does
not issue fractions of a share, it shall (1) arrange for the disposition of
fractional interests by those entitled thereto, (2) pay in cash the fair value
of fractions of a share as of the time when those entitled to receive such
fractions are determined, or (3) issue scrip or warrants in registered form
(either represented by a certificate or uncertificated) or bearer form
(represented by a certificate) which shall entitle the holder to receive a full
share upon the surrender of such scrip or warrants aggregating a full share. A
certificate for a fractional share or an uncertificated fractional share shall,
but scrip or warrants shall not unless otherwise provided therein, entitle the
holder to exercise voting rights, to receive dividends thereon, and to
participate in any of the assets of the Corporation in the event of liquidation.
The Board of Directors may cause scrip or warrants to be issued subject to the
conditions that they shall become void if not exchanged for certificates
representing the full shares or uncertificated full shares before a specified
date, or subject to the conditions that the shares for which scrip or warrants
are exchangeable way be sold by the Corporation and the proceeds thereof
distributed to the holders of scrip or warrants, or subject to any other
conditions which the Board of Directors may impose.

                  4.       STOCK TRANSFERS. Upon compliance with provisions
restricting the transfer or registration of transfer of shares of stock, if any,
transfers or registration of transfers of shares of stock of the Corporation
shall be made only on the stock ledger of the Corporation by the registered
holder thereof, or by his attorney thereunto authorized by power of attorney
duly executed and filed with the secretary of the Corporation or with a transfer
agent or a registrar, if any, and, in the case of shares represented by
certificates, on surrender of the certificate or certificates for such shares of
stock properly endorsed and the payment of all taxes due thereon.

                  5.       RECORD DATE FOR STOCKHOLDERS. In order that the
Corporation may determine the stockholders entitled to notice of or to vote at
any meeting of stockholders or any adjournment thereof, the Board of Directors
may fix a record date, which record date shall not precede the date upon which
the resolution fixing the record date is adopted by the Board of Directors, and
which record date shall not be more than sixty nor less than ten days before the
date of such meeting. If no record date is fixed by the Board of Directors, the
record date for determining stockholders entitled to notice of or to vote at a
meeting of stockholders shall be at the close of business on the day next
preceding the day on which notice is given, or, if notice is waived, at the
close of business on the day next preceding the day on which the meeting is
held. A determination of stockholders of record entitled to notice of or to vote
at a meeting of stockholders shall apply to any adjournment of the meeting;
provided, however, that the Board of Directors may fix a new record date for the
adjourned meeting. In order that the Corporation may determine the stockholders
entitled to receive payment of any dividend or other distribution or allotment
of any rights or the stockholders entitled to exercise any rights in respect of
any change, conversion, or exchange of stock, or for the purpose of any

                                        2

<PAGE>   3



other lawful action, the Board of Directors may fix a record date, which record
date shall not precede the date upon which the resolution fixing the record date
is adopted, and which record date shall be not more than sixty days prior to
such action. If no record date is fixed, the record date for determining
stockholders for any such purpose shall be at the close of business on the day
on which the Board of Directors adopts the resolution relating thereto.

                  6.       MEANING OF CERTAIN TERMS. As used herein in respect
of the right to notice of a meeting of stockholders or a waiver thereof or to
participate or vote thereat or to consent or dissent in writing in lieu of a
meeting, as the case may be, the term "share" or "shares" or "shares of stock"
or "shares of stock" or "stockholder" or "stockholders" refers to an outstanding
share or shares of stock and to a holder or holders of record of outstanding
shares of stock when the Corporation is authorized to issue only one class of
shares of stock, and said reference is also intended to include any outstanding
share or shares of stock and any holder or holders of record of outstanding
shares of stock of any class upon which or upon whom the certificate of
incorporation confers such rights where there are two or more classes or series
of shares of stock or upon which or upon whom a General corporation Law confers
such rights notwithstanding that the certificate of incorporation may provide
for more than one class or series of shares of stock, one or more of which are
limited or denied such rights thereunder; provided, however, that no such right
shall vest in the event of an increase or a decrease in the authorized number of
shares of stock of any class or series which is otherwise denied voting rights
under the provisions of the certificate of incorporation, except as any
provision of law may otherwise require.

                  7.       STOCKHOLDER MEETINGS.

                  --TIME. The annual meeting shall be held on the date and at
the time fixed, from time to time, by the directors, provided, that the first
annual meeting shall be held on a date within thirteen months after the
organization of the Corporation, and each successive annual meeting shall be
held an a date within thirteen months after the date of the preceding annual
meeting. A special meeting shall be hold on the date and at the time fixed by
the directors.

                  --PLACE. Annual meetings and special meetings shall be held at
such place, within or without the State of Delaware, as the directors may, from
time to time, fix. Whenever the directors shall fail to fix such place, the
meeting shall be held at the registered office of the Corporation in the State
of Delaware.

                  --CALL. Annual meetings and special meetings may be called by
the directors or by any officer instructed by the directors to call the meeting.

                  --NOTICE OR WAIVER OF NOTICE. Written notice of all meetings
shall be given, stating the place, date, and hour of the meeting and stating the
place within the city or other municipality or community at which the list of
stockholders of the Corporation may be examined. The notice of an annual meeting
shall state that the meeting is called for the election of directors and for the
transaction of other business which may properly come before the

                                        3

<PAGE>   4



meeting, and shall (if any other action which Could be taken at a special
meeting is to be taken at such annual meeting) state the purpose or purposes.
The notice of a special meeting shall in all instances state the purpose or
purposes for which the meeting is called. The notice of any meeting shall also
include, or be accompanied by any additional statements, information, or
documents prescribed by the General Corporation Law. Except as otherwise
provided by the General Corporation Law, a copy of the notice of any meeting
shall be given, personally or by mail, not less than ten days nor more than
sixty days before the date of the meeting, unless the lapse of the prescribed
period of time shall have been waived, and directed to each stockholder at his
record address or at such other address which he may have furnished by request
in writing to the Secretary of the Corporation. Notice by mail shall be deemed
to be given when deposited, with postage thereon prepaid, in the United States
Mail. If a meeting is adjourned to another time, not more than thirty days
hence, and/or to another place, and if an announcement of the adjourned time
and/or place is made at the meeting, it shall not be necessary to give notice of
the adjourned meeting unless the directors, after adjournment, fix a new record
date for the adjourned meeting. Notice need not be given to any stockholder who
submits a written waiver of notice signed by him before or after the time stated
therein. Attendance of a stockholder at a meeting of stockholders shall
constitute a waiver of notice of such meeting, except when the stockholder
attends the meeting for the express purpose of objecting, at the beginning of
the meeting, to the transaction of any business because the meeting is not
lawfully called or convened. Neither the business to be transacted at, nor the

despite the absence of a quorum.

majority of the votes cast except where the General Corporation Law prescribes a
different percentage of votes and/or a different exercise of voting power, and
except as may be otherwise prescribed by the provision of the Certificate of
Incorporation and the Bylaws, as amended. In the election of directors, and for
any other action, voting need not be by ballot.

                                   ARTICLE II

                                    DIRECTORS

                  1.       FUNCTIONS AND DEFINITION. The business and affairs of
the Corporation shall be managed by or under the direction of the Board of
Directors of the Corporation. The Board of Directors shall have the authority to
fix the compensation of the members thereof. The use of the phrase "whole board"
herein refers to the total number of directors which the Corporation would have
if there were no vacancies.

                  2.       QUALIFICATIONS AND NUMBER. A director need not be a
stockholder, a citizen of the United States, or a resident of the State of
Delaware. The Board of Directors shall consist of not fewer than three (3)
members and not more than twelve (12) members, the exact number of authorized
directors within such range to be fixed from time to time by a resolution of the
Board of Directors adopted by the affirmative vote of at least a majority of the
total number of authorized directors most recently fixed by the Board of
Directors.

                  3.       ELECTION AND TERM.

                  (a) The directors of the Corporation shall be divided into
         three classes for the purpose of determining their terms of office.
         Each such class shall consist, as nearly as possible, of one-third of
         the total number of directors fixed by the Board of Directors. At the
         annual meeting of stockholders of the Corporation held in 1998, one
         class of directors (designated as Class I) shall be elected for a term
         expiring at the annual meeting of stockholders of the Corporation held
         in 1999, one class of directors (designated as Class II) shall be
         elected for a term expiring at the annual meeting of stockholders of
         the Corporation held in 2000, and one class of directors (designated as
         Class III) shall be elected for a term expiring at the annual meeting
         of stockholders of the Corporation held in 2001. At each succeeding
         annual meeting of stockholders of the Corporation, beginning in 1999,
         successors to the class of directors whose term expires at that annual
         meeting shall be elected for a term expiring at the annual meeting of
         stockholders of the Corporation held in the third year following the
         year of their election.

                  (b) If the number of directors is changed, then any increase
         or decrease in such number shall be apportioned by the Board of
         Directors among the classes of directors so as to maintain as nearly as
         possible an equal number of directors in each class. No

                                        6

<PAGE>   7



         reduction in the authorized number of members of the Board of directors
         shall have the effect of removing any director from office before that
         director's term of office expires.

                  (c) Vacancies on the Board of Directors and newly created
         directorships resulting from an increase in the authorized number of
         members of the Board of Directors may be filled only by a majority of
         the directors, then in office, although less than a quorum, or by a
         sole remaining director.

                  (d) Each director, including a director elected to fill a
         vacancy or a newly created directorship, shall hold office until the
         next election of the class of directors to which such director belongs
         and until his or her successor is elected and qualified or until his or
         her earlier death, resignation, or removal from office for cause.

                  (e) Any director may resign at any time upon written notice to
         the Corporation

                  (f) Any director or the entire Board of Directors may be
         removed from any office at any time but 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 of the Corporation
         then entitled to vote in an election of directors of the Corporation,
         voting as a single class.

                  (g) A majority of total directors shall constitute a quorum
         for the transaction of business.

                  (h) Notwithstanding the foregoing, whenever the holders of any
         one or more classes or series of stock issued by the Corporation shall
         have the right, voting separately by class or series, to elect
         directors at an annual or special meeting of stockholders, the
         election, term of office, filing of vacancies and other features of
         such directorships shall be governed by the terms of the Certificate of
         Incorporation of the Corporation applicable thereto, such directors so
         elected shall not be divided into classes pursuant to Article VII of
         the Certificate of Incorporation, and the number of such directors
         shall not be counted in determining the maximum number of directors
         permitted under the foregoing provision of Article VII of the Restated
         Certificate of Incorporation, in each case unless expressly provided by
         such terms.

                  (i) Nominations of persons for election to the Board of
         Directors may be made at a meeting of stockholders of the Corporation
         either by or at the direction of the Board of Directors or by any
         stockholder or record entitled to vote in the election of directors at
         such meeting who has complied with the notice procedures set forth in
         this paragraph. A stockholder who desires to nominate a person for
         election to the Board of Directors at a meeting of stockholders of the
         Corporation and who is eligible to make such nomination must give
         timely written notice of the proposed nomination to the secretary of
         the Corporation. To be timely, a stockholder's notice given pursuant to
         this paragraph must be received at the principal executive office of
         the Corporation not less

         than one hundred twenty (120) calendar days in advance of the date
         which is one year later than the date of the proxy statement of the
         Corporation released to stockholders in connection with the previous
         year's annual meeting of stockholders of the Corporation; provided,
         however, that if no annual meeting of stockholders of the Corporation
         was held in the previous year or if the date of the forthcoming annual
         meeting of stockholders has been changed by more than thirty (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 of the Corporation, 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 the Corporation or (b) the day on which
         public disclosure of the date of the forthcoming meeting was made by or
         on behalf of the Corporation. Such stockholder's notice to the
         secretary of the Corporation shall set forth (a) as to each person whom
         the stockholder proposes to nominate for election or re-election as a
         director (i) the name, age, business address and residence address of
         such person, (ii) the principal occupation or employment of such

         Corporation which then are beneficially owned by such person, (iv) any
         other information relating to such person that is required by law or
         regulation to be disclosed in solicitations of proxies for the election
         of directors of the Corporation, and (v) such person's written consent
         to being named as a nominee for election as a director and to serve as
         a director if elected and (b) as to the stockholder giving notice (i)
         the name and address, as they appear in the stock records of the
         Corporation, of such stockholder, (ii) the class and number of shares
         of capital stock of the Corporation which then are beneficially owned
         by such stockholder, (iii) a description of all arrangements or
         understandings between such stockholder and each nominee for election
         as director and any other person or persons (naming such person or
         persons) relating to the nomination proposed to be made by such
         stockholder, and (iv) any other information required by law or
         regulation to be provided by a stockholder intending to nominate a
         person for election as a director of the Corporation. At the request of
         the Board of Directors, any person nominated by or at the direction of
         the Board of Directors for election as director of the Corporation
         shall furnish to the secretary of the Corporation the information
         concerning such nominee which is required to be set forth in a
         stockholder's notice of a proposed nomination. No person shall be
         eligible for election as a director of the Corporation unless nominated
         in compliance with the procedures set forth in this paragraph. The
         chairman of a meeting of stockholders of the Corporation shall refuse
         to accept the nomination of any person not made in compliance with the
         procedures set forth in this paragraph, and such defective nomination
         shall be disregarded.

                  4.       MEETINGS.

one or more of the directors of the Corporation. The Board may designate one or
more directors as alternate members of any committee, who may replace any absent

or members thereof present at any meeting and not disqualified from voting,

absent or disqualified member. Any such committee, to the extent provided in the
resolution or the Board, shall have and may exercise the powers and authority of
the Board of Directors in the management of the business and affairs of the
Corporation with the exception of any authority the delegation of which is
prohibited by Section 141 of the General Corporation Law, and may authorize the
seal of the Corporation to be affixed to all papers which may require it.

                  6. WRITTEN ACTION. Any action required or permitted to be
taken at any meeting of the Board of Directors or any committee thereof may be
taken without a Meeting if all members of the Board or committee, as the case
may be, consent thereto in writing, and the writing or writings are filed with
the minutes of proceedings of the Board or committee.

Gentlemen:
 
     We have acted as counsel to 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, of an aggregate of up to 27,000,000 shares
of common stock, $.01 par value per share, of the Company (the "Shares").
 
     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.
 
     We are members of the Bar of, and are admitted to practice only in, the
State of Georgia. Accordingly, except as to the General Corporation Law of the
State of Delaware ("DGCL"), we express no opinion herein as to the laws of any
jurisdiction other than the United States and the State of Georgia. Except as to
the DGCL, to the extent that any of the opinions contained herein requires
consideration of the laws of a state other than the State of Georgia, we have
assumed, with your permission, that the laws of such states are the same as the
laws of the State of Georgia.
 
     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 DGCL and its Certificate
of Incorporation and By-Laws to issue the Shares, and the Shares, when issued
against payment therefor, 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 Prospectus which is a part of the Registration Statement.
 
                                          Very truly yours,

wholly-owned subsidiary of WAXS with and into the Company (the "NACT Merger"),
and issuable to holders of the capital stock of World Access, Inc. ("World
Access") in the merger of a wholly-owned subsidiary of WAXS with and into World
Access ("World Access Merger") as described in the Registration Statement and in
the Plan and Agreement of Merger dated February 24, 1998, as amended, among the
parties (the "Merger Agreement").
 
     In our opinion, the discussion with respect to Federal tax matters
contained under the caption "The Transaction -- Federal Income Tax
Consequences -- NACT Merger" in the Prospectus/Information Statement that is
part of the Registration Statement sets forth the material Federal income tax
consequences of the NACT Merger. The discussion does not address all aspects of
Federal income taxation that may be important to particular taxpayers in light
of their personal investment circumstances or to taxpayers who are subject to
special treatment under the Federal income tax laws (such as a life insurance
company, foreign person, tax-exempt entity, a holder who acquired his NACT
common stock pursuant to the exercise of employee stock options or otherwise as
compensation and a person who holds, directly or indirectly, 10% or more of the
common stock of NACT).
 
     In rendering this opinion, we have relied upon the factual representations
of the parties contained in the Registration Statement and certain
representation letters. We have not independently investigated or verified any
such facts, and, we do not herein opine as to or confirm the accuracy or
completeness thereof. Furthermore, in rendering this opinion we have assumed
that the common stock of NACT will be held as a capital asset at the time of the
consummation of the NACT Merger. This opinion is based upon current law and
assumes that both the NACT Merger and the World Access Merger will be
consummated as described in the Prospectus/Information Statement that is part of
the Registration Statement and in accordance with the Merger Agreement and
related agreements in their current form.
 
     This opinion is being provided solely for the benefit of NACT and holders
of NACT Common Stock. No other person or party shall be entitled to rely on this
opinion.
 
     We consent to the use of this opinion as an exhibit to the Registration
Statement and to the reference to our firm under the caption "The
Transaction -- Federal Income Tax Consequences -- NACT Merger" in the
Prospectus/Information Statement that is part of the Registration Statement. In
giving this consent, we do not thereby admit that we come within the category of
persons whose consent is required under Section 7 of the Securities Act of 1933,
as amended.
 
                                      Very truly yours,

Ladies and Gentlemen:
 
     We have acted as your counsel in connection with the transactions
contemplated by the Amended and Restated Agreement and Plan of Merger (the
"Merger Agreement") dated as of February 24, 1998, as amended as of June 30,
1998 and as of September 18, 1998 among World Access, Inc., a Delaware
corporation ("World Access"), WAXS INC., a Delaware corporation and a direct
wholly owned subsidiary of World Access ("Holdco"), WAXS Acquisition Corp., a
Delaware corporation and a direct wholly owned subsidiary of Holdco ("WAXS
Merger Sub"), NACT Telecommunications, Inc., a Delaware Corporation ("NACT"),
and NACT Acquisition Corp., a Delaware corporation and a direct wholly owned
subsidiary of Holdco ("NACT Merger Sub"). Pursuant to the Merger Agreement, WAXS
Merger Sub will be merged with and into World Access and NACT Merger Sub will be
merged with and into NACT. In that connection we have participated in the
preparation of a registration statement under the Securities Act of 1993, as
amended, on Form S-4 (the "Registration Statement"), including an Information
Statement/Prospectus (the "Information Statement"). (Capitalized terms not
otherwise defined herein shall have the meanings specified in the Information
Statement.)
 
     We have examined the Merger Agreement, the Information Statement, the
representation letters of World Access and NACT (the "Representation Letters")
delivered to us for purposes of this opinion, and such other documents and
corporate records as we have deemed necessary or appropriate for purposes of
this opinion. In addition, we have assumed that (i) the NACT Transaction will be
consummated in the manner contemplated in the Information Statement and in
accordance with the provisions of the Merger Agreement, (ii) the statements
concerning the NACT Transaction set forth in the Information Statement are
accurate and complete, and (iii) the representations made to us in the
Representation Letters are accurate and complete.
 
     Based upon and subject to the foregoing, the description of the Federal
income tax consequences to certain holders of outstanding shares of World Access
Common Stock contained in the Information Statement under the heading (and the
subheadings thereof) "THE NACT TRANSACTION -- Federal Income Tax
Consequences -- World Access Merger" (including the discussion contained in the
second paragraph thereof), represents our opinion, subject to the qualifications
set forth therein.
 
     Our opinion is limited to the tax matters specifically covered hereby.
 
     This opinion is being provided solely for the benefit of World Access and
holders of World Access Common Stock. No other person or party shall be entitled
to rely on this opinion.
 
     We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the references to this Firm in the section
captioned "THE NACT TRANSACTION -- Federal Income Tax Consequences" in the
Information Statement constituting a part of the Registration Statement. In
giving this

thereunder.
